    During the last 20 years, numerous studies have highlighted the need to consider Quality of Life (QoL) issues in the treatment of brain cancer. However, gaps in scientific knowledge are still present as we have poor data surrounding the whole experience in patients and regarding their needs. The present study was aimed at evaluating QoL in brain cancer patients and correlated aspects. In particular, we aimed to assess QoL, mood state, and emotional issues in order to describe the patients’ experience to find out the critical aspects involved. Methods We obtained data from 85 patients during chemotherapy treatment at the National Neurological Institute ‘C. Besta’ of Milan, Italy. We used standardised questionnaires to assess different aspects of patients’ QoL. In particular, the functional assessment of cancer therapy-brain (FACT-Br) and the Hamilton scale were used. We also performed a semi-structured ad hoc interview in order to collect ­narrative data about patients’ experience. Results Our data depict a difficult adjustment process to the illness, even though positive elements emerged. Indeed, patients reported a satisfying self-perceived QoL, although specific concerns are still present. Further, even if many patients report depressive symptoms, only a minority have a severe condition. Conclusion Brain cancer may heavily affect patients’ QoL and well being. However, some element of the context may improve the ­adjustment to the disease. In particular, we found that most patients found psychosocial resources to cope with cancer and that spiritual well being also seems to play a key role. These issues deserve further studies in order to obtain significant clinical recommendations. PMID:26635895

    Brain metastases in breast cancer develop for 24-32 months after the detection of the primary tumor. The study included patients with brain metastases who were divided into three groups: the first group--with early chemoradiotherapy (CRT) without induction chemotherapy (IC) by capecitabine; the second group--with delayed CRT with 4 or 8 courses of IC by capecitabine; the third group (a historical control) who received only whole brain radiation therapy. The median time to progression of intracranial metastases was 15.3, 12 and 5 months, respectively. The median time to the intracranial progression significantly less in the third group (5 months) compared with the first (15.3 months) (p = 0.0007) and the second (12 months) (p = 0.027) groups. The overall survival rate was 22.1, 15.1 and 6.8 months in three groups, respectively. PMID:26995988

    Preclinical data have demonstrated that ionizing radiation acts synergistically with capecitabine. This report retrospectively assessed the use of capecitabine concurrently with whole-brain radiotherapy (WBRT) in patients with brain metastases from breast cancer. From January 2003 to March 2005, five breast cancer patients with brain metastases were referred for WBRT with concurrent capecitabine. Median age was 44 years (range: 38-53). The median dose of capecitabine was 1,000 mg/m(2) twice daily for 14 days (day1-14). Treatment cycles were repeated every 21 days, concurrently with WBRT (30 Gy, 3 Gy per fraction, 5 days per week). Median survival after starting WBRT plus capecitabine was 6.5 months (range 1-34 months). One patient achieved a complete response. Two patients achieved partial response, including one with local control lasting until most recent follow-up. One patient had stable disease. The remaining patient was not assessable for response because of early death. Most commonly reported adverse events were nausea (n = 2) and headache (n = 2), always grade 1. Other toxicities were grade 3 hand/foot syndrome (n = 1), moderate anemia requiring transfusion and dose reduction of capecitabine (n = 1), and grade 1 mucositis (n = 1). Although promising, these preliminary data warrant further assessment of capecitabine-based chemoradiation in brain metastases from breast cancer and need to be further validated in the setting of a clinical trial.

    Breast cancer is the second most common cause of brain metastases and deserves particular attention in relation to current prolonged survival of patients with metastatic disease. Advances in both systemic therapies and brain local treatments (surgery and stereotactic radiosurgery) have led to a reappraisal of brain metastases management. With respect to this, the literature review presented here was conducted in an attempt to collect medical evidence-based data on the use of whole-brain radiotherapy for the treatment of brain metastases from breast cancer. In addition, this study discusses here the potential differences in outcomes between patients with brain metastases from breast cancer and those with brain metastases from other primary malignancies and the potential implications within a treatment strategy.

    Purpose: The aim of the study was to present a new breast cancer recursive partitioning analysis (RPA) prognostic index for patients with newly diagnosed brain metastases as a guide in clinical decision making. Methods and Materials: A prospectively collected group of 441 consecutive patients with breast cancer and brain metastases treated between the years 2003 and 2009 was assessed. Prognostic factors significant for univariate analysis were included into RPA. Results: Three prognostic classes of a new breast cancer RPA prognostic index were selected. The median survival of patients within prognostic Classes I, II, and III was 29, 9, and 2.4 months, respectively (p < 0.0001). Class I included patients with one or two brain metastases, without extracranial disease or with controlled extracranial disease, and with Karnofsky performance status (KPS) of 100. Class III included patients with multiple brain metastases with KPS of {<=}60. Class II included all other cases. Conclusions: The breast cancer RPA prognostic index is an easy and valuable tool for use in clinical practice. It can select patients who require aggressive treatment and those in whom whole-brain radiotherapy or symptomatic therapy is the most reasonable option. An individual approach is required for patients from prognostic Class II.

    Purpose: To assess the use of trastuzumab concurrently with whole brain radiotherapy (WBRT) for patients with brain metastases from human epidermal growth factor receptor-2-positive breast cancer. Methods and Materials: Between April 2001 and April 2007, 31 patients with brain metastases from human epidermal growth factor receptor-2-positive breast cancer were referred for WBRT with concurrent trastuzumab. At brain progression, the median age was 55 years (range, 38-73), and all patients had a performance status of 0-2. The patients received trastuzumab 2 mg/kg weekly (n = 17) or 6 mg/kg repeated every 21 days (n = 14). In 26 patients, concurrent WBRT delivered 30 Gy in 10 daily fractions. In 6 patients, other fractionations were chosen because of either poor performance status or patient convenience. Results: After WBRT, radiologic responses were observed in 23 patients (74.2%), including 6 (19.4%) with a complete radiologic response and 17 (54.8%) with a partial radiologic response. Clinical responses were observed in 27 patients (87.1%). The median survival time from the start of WBRT was 18 months (range, 2-65). The median interval to brain progression was 10.5 months (range, 2-27). No Grade 2 or greater acute toxicity was observed. Conclusion: The low toxicity of trastuzumab concurrently with WBRT should probably not justify delays. Although promising, these preliminary data warrant additional validation of trastuzumab as a potential radiosensitizer for WBRT in brain metastases from breast cancer in the setting of a clinical trial.

    Glioblastoma multiforme is a heterogeneous and infiltrative cancer with dismal prognosis. Studying the migratory behavior of tumor-derived cell populations can be informative, but it places a high premium on the precision of in vitro methods and the relevance of in vivo conditions. In particular, the analysis of 2D cell migration may not reflect invasion into 3D extracellular matrices in vivo. Here, we describe a method that allows time-resolved studies of primary cell migration with single-cell resolution on a fibrillar surface that closely mimics in vivo 3D migration. We used this platform to screen 14 patient-derived glioblastoma samples. We observed that the migratory phenotype of a subset of cells in response to platelet-derived growth factor was highly predictive of tumor location and recurrence in the clinic. Therefore, migratory phenotypic classifiers analyzed at the single-cell level in a patient-specific way can provide high diagnostic and prognostic value for invasive cancers. PMID:27292647

    The incidence of brain metastases from breast cancer is increasing with diagnosis and therapeutics progress, especially with systemic therapies. The occurrence of multiple brain metastases remains a delicate situation when surgery and stereotactic radiosurgery are not indicated, nor available. Treatment strategy is based on the patient's general condition and extracranial disease status. Whole brain radiation therapy remains the gold standard local treatment but its efficacy is limited with a median overall survival of 6 months. New strategies are needed for increasing survival and patients' quality of life. Combining radiation therapy and chemotherapy has been a subject of interest. This article sums up the different radiotherapy plus concomitant systemic therapies combinations for the treatment of brain metastases from breast cancer. PMID:24731405

    Cancer patients without evidence of brain metastases often exhibit constitutional symptoms, cognitive dysfunction and mood changes at the time of clinical diagnosis, i.e. prior to surgical and/or chemotherapy treatment. At present however, there is limited information on brain metabolic and functional status in patients with systemic cancers such as lung cancer prior to initiation of treatment. Therefore, a prospective, observational study was conducted on patients with a clinical diagnosis of lung cancer to assess the cerebral metabolic status before treatment using proton magnetic resonance spectroscopy (1HMRS). Together with neurocognitive testing, 1HMRS was performed in the parietal and occipital cortices of patients diagnosed with a lung mass (N=17) and an age-matched control group (N=15). Glutamate concentrations in the occipital cortex were found to be lower in the patients compared to controls and the concentrations of creatine and phosphocreatine were significantly lower in the parietal cortex of the patients. The lung cancer patients were also characterized by greater fatigue scores (but not depression) prior to treatment when compared to controls. In addition, the serum concentration of interleukin-6 (proinflammatory cytokine) was higher in patients compared to controls; and the concentration of tumor-necrosis factor alpha ([TNF-α]) was positively correlated to the metabolic activity of the lung tumor as defined by the 2-deoxy-2-(18F)fluoro-D-glucose (18FDG) positron emission tomography (PET) derived maximal standardized uptake values (SUVmax). Finally, multivariate statistical modeling revealed that the concentration of N-acetyl-aspartate [NAA] in the occipital cortex was negatively associated with [TNF-α]. In conclusion, our data demonstrate that the cerebral metabolic status of patients with lung cancer is changed even prior to treatment. In addition, the association between inflammatory cytokines, SUVmax and [NAA] points towards interactions

    The prediction of substantially short survivability in patients is extremely risky. In this study, we proposed a probabilistic model using Bayesian network (BN) to predict the short survivability of patients with brain metastasis from lung cancer. A nationwide cancer patient database from 1996 to 2010 in Taiwan was used. The cohort consisted of 438 patients with brain metastasis from lung cancer. We utilized synthetic minority over-sampling technique (SMOTE) to solve the imbalanced property embedded in the problem. The proposed BN was compared with three competitive models, namely, naive Bayes (NB), logistic regression (LR), and support vector machine (SVM). Statistical analysis showed that performances of BN, LR, NB, and SVM were statistically the same in terms of all indices with low sensitivity when these models were applied on an imbalanced data set. Results also showed that SMOTE can improve the performance of the four models in terms of sensitivity, while keeping high accuracy and specificity. Further, the proposed BN is more effective as compared with NB, LR, and SVM from two perspectives: the transparency and ability to show the relation of factors affecting brain metastasis from lung cancer; it allows decision makers to find the probability despite incomplete evidence and information; and the sensitivity of the proposed BN is the highest among all standard machine learning methods.

    Purpose: To elucidate survival times and identify potential prognostic factors in patients with triple-negative (TN) phenotype who harbored brain metastases arising from breast cancer and who underwent stereotactic radiosurgery (SRS). Methods and Materials: A total of 103 breast cancer patients with brain metastases were treated with SRS and then studied retrospectively. Twenty-four patients (23.3%) were TN. Survival times were estimated using the Kaplan-Meier method, with a log-rank test computing the survival time difference between groups. Univariate and multivariate analyses to predict potential prognostic factors were performed using a Cox proportional hazard regression model. Results: The presence of TN phenotype was associated with worse survival times, including overall survival after the diagnosis of primary breast cancer (43 months vs. 82 months), neurologic survival after the diagnosis of intracranial metastases, and radiosurgical survival after SRS, with median survival times being 13 months vs. 25 months and 6 months vs. 16 months, respectively (p < 0.002 in all three comparisons). On multivariate analysis, radiosurgical survival benefit was associated with non-TN status and lower recursive partitioning analysis class at the initial SRS. Conclusion: The TN phenotype represents a significant adverse prognostic factor with respect to overall survival, neurologic survival, and radiosurgical survival in breast cancer patients with intracranial metastasis. Recursive partitioning analysis class also served as an important and independent prognostic factor.

    Background: Patients with small-cell lung cancer have a high likelihood of developing brain metastases. Many of these patients will have prophylactic cranial irradiation (PCI) or eventually undergo whole brain radiation therapy (WBRT). Despite these treatments, a large number of these patients will have progression of their intracranial disease and require additional local therapy. Stereotactic radiosurgery (SRS) is an important treatment option for such patients. Methods: We retrospectively reviewed the charts of 44 patients with brain metastases from small-cell lung cancer treated with gamma knife SRS. Multivariate analysis was used to determine significant prognostic factors influencing survival. Results: The median follow-up from SRS in this patient population was 9 months (1-49 months). The median overall survival (OS) was 9 months after SRS. Karnofsky performance status (KPS) and combined treatment involving WBRT and SRS within 4 weeks were the two factors identified as being significant predictors of increased OS (p = 0.033 and 0.040, respectively). When comparing all patients, patients treated with a combined approach had a median OS of 14 months compared to 6 months if SRS was delivered alone. We also compared the OS times from the first definitive radiation: WBRT, WBRT and SRS if combined therapy was used, and SRS if the patient never received WBRT. The median survival for those groups was 12, 14, and 13 months, respectively, p = 0.19. Seventy percent of patients had follow-up magnetic resonance imaging available for review. Actuarial local control at 6 months and 12 months was 90% and 86%, respectively. Only 1 patient (2.2%) had symptomatic intracranial swelling related to treatment, which responded to a short course of steroids. New brain metastases outside of the treated area developed in 61% of patients at a median time of 7 months; 81% of these patients had received previous WBRT. Conclusions: Stereotactic radiosurgery for small-cell lung carcinoma

    Objective The primary purpose of this study was to clarify the influence of the early response to surgery on brain structure and cognitive function in patients with breast cancer. It was hypothesized that the structure of the thalamus would change during the early response after surgery due to the effects of anesthesia and would represent one aspect of an intermediate phenotype of postoperative cognitive dysfunction (POCD). Methods We examined 32 postmenopausal females with breast cancer and 20 age-matched controls. We assessed their cognitive function (attention, memory, and executive function), and performed brain structural MRI 1.5 ± 0.5 days before and 5.6 ± 1.2 days after surgery. Results We found a significant interaction between regional grey matter volume (rGMV) in the thalamus (P < 0.05, familywise error (FWE), small volume correction (SVC)) and one attention domain subtest (P = 0.001, Bonferroni correction) after surgery in the patient group compared with the control group. Furthermore, the changes in attention were significantly associated with sevoflurane anesthetic dose (r2 = 0.247, β = ‒0.471, P = 0.032) and marginally associated with rGMV changes in the thalamus (P = 0.07, FWE, SVC) in the Pt group. Conclusion Our findings suggest that alterations in brain structure, particularly in the thalamus, may occur shortly after surgery and may be associated with attentional dysfunction. This early postoperative response to anesthesia may represent an intermediate phenotype of POCD. It was assumed that patients experiencing other risk factors of POCD, such as the severity of surgery, the occurrence of complications, and pre-existing cognitive impairments, would develop clinical POCD with broad and multiple types of cognitive dysfunction.

    Thromboembolism that occurs in association with a malignant tumor is known as Trousseau syndrome. We herein present a case of Trousseau syndrome during systemic chemotherapy for metastatic colon cancer. A 65-year-old man with multiple liver metastases underwent primary tumor resection and systemic chemotherapy. Multiple brain infarctions were detected by magnetic resonance imaging immediately after first-line chemotherapy, which was deemed ineffective. There was no evidence of cardioembolic stroke or carotid atherosclerosis. Although the patient was initially asymptomatic, he subsequently developed paralysis. Despite anticoagulant treatment, he developed repeated recurrences of the infarction, and the area of the infarction spread as the liver metastases progressed. The patient's condition showed no response to an alternative treatment regimen for advanced colon carcinoma. He died approximately 11 months after tumor discovery. PMID:27595586

    This article describes the experience of the author in providing nursing care to a lung cancer patient with brain metastasis who was unable to care for herself. The period of care ran from July 26th to August 7th, 2012. The focus of the article is on the problems of disease adaptation and the coping strategies of the patient and her primary caregivers. The author used the Family Resiliency Model to collect information via physical examination, observation, and interviews. Five major nursing problems were identified in this case: risk of aspiration, self-care deficits, adjustment disorder, caregiver role strain, and family coping ineffectiveness. Based on these problems, the author constructed an individualized care plan to: 1) improve the self-care ability of the patient, 2) enhance the skills of the primary caregiver, 3) recruit the timely assistance of other family members, 4) and reduce the burden of the primary caregiver. The primary goal of this care plan was to promote the quality of life of the patient and her family. PMID:25464963

    A substantial burden is placed on family caregivers of patients diagnosed with brain cancers. Despite this, the support needs of the caregivers are often under-recognised and not addressed adequately in current routine and patient centred clinical care. The Care Support Needs Assessment Tool (CSNAT) is a validated instrument designed to systematically identify and address caregiver needs. It has been trialled in an Australian palliative care community setting using a stepped wedge cluster design involving 322 family carers of terminally ill patients. The current article reports on a subset from this trial, 29 caregivers of patients with primary brain cancer, and compares their profile and outcomes to those of other cancer groups. Caregiver strain was assessed using the Family Appraisal of Caregiving Questionnaire, caregiver physical and mental wellbeing using SF12 and caregiver workload using a questionnaire on support with activities of daily living (ADL). In comparison to caregivers of patients with all other cancers, the primary brain cancer group had significantly higher levels of caregiver strain, lower levels of mental wellbeing and a higher level of ADL workload. Their physical wellness also deteriorated significantly over time. An action plan approach led to practical solutions for addressing highlighted concerns. Four themes evolved from the family caregivers’ feedback interviews: The extremely challenging caregiver experience with brain cancer; the systematic and practical approach of the CSNAT during rapid changes; connection with health professionals, feeling acknowledged and empowered; and timely advice and assurance of support during the caregiving journey. This preliminary study has demonstrated that the CSNAT provides a practical and useful tool for assessing the support needs of family caregivers of patients with brain cancer and has provided the basis for a larger scale, longitudinal study that allows a more detailed characterisation of the

    Cancers of the breast, kidney, lungs, prostate and thyroid metastasize to the musculoskeletal system in the majority of patients with malignancy. This report chronicles the case of a 65-year-old female with a known history of breast cancer who presented to a chiropractic clinic. Once metastasis was ruled out as the cause of her complaint, the patient was treated with manual therapies and exercises. As the patient’s treatments progressed and her pain improved, she presented with a new complaint of ‘pressure’ in her head. Advanced imaging revealed metastasis to the brain and subsequently to the spine. The aim of this case is to heighten awareness of the presentation of metastasis to the brain and the spine in a chiropractic patient, and to demonstrate the benefit of chiropractic care in the management of such patients.

    Purpose: To examine prospectively patient self-rated symptoms and quality of life (QOL) indicators in patients with brain metastases following whole brain radiotherapy (WBRT). Methods and Materials: Consecutive patients with brain metastases referred for WBRT were approached for this study. Patients were asked to rate their symptoms and QOL using the Spitzer Quality of Life Index questionnaire. Follow-up was at 1, 2, and 3 months following WBRT. Linear regression analysis was used to determine the change in symptom severity over time. Results: Between August 2005 to October 2007, 129 patients with brain metastases were enrolled. The majority of patients (88%) received 20 Gy in five fractions. Median age was 64 years, and median Karnofsky Performance Status at baseline was 70. The most commonly experienced symptoms at baseline were headaches, weakness, balance problems, and fatigue. Thirty-five percent of patients rated neurological functional (NF) status as 1, indicating moderate neurological symptoms and need for assistance. Forty-three percent of patients had stable or decreased fatigue, and 47% had a stable or improved NF status over time (p = 0.0040). Although certain QOL domains improved over time, all other QOL domains and symptom items did not change significantly following WBRT. Conclusion: WBRT may have contributed to symptom stabilization in our study. An alternative goal of WBRT may be the prevention of symptom progression and QOL deterioration. Further research is required to select the most appropriate group of patients with brain metastases who would benefit most from WBRT.

    Background Lung cancer is the most common type of cancer to spread to the brain (brain metastasis [BM]). This study assessed the effect of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in combination with whole-brain radiotherapy (WBRT) on EGFR-mutant non-small-cell lung cancer (NSCLC) patients with BM. Patients and methods Thirty-nine patients, who had receieved different EGFR TKIs plus 30 Gy WBRT until disease progression, were retrospectively analyzed between 2010 and 2014. Treatment response was evaluated and survival data were collected and analyzed. Results Among the 39 patients, 18 had an EGFR exon 19 deletion and 21 had an EGFR exon 21 point mutation. After therapy, 19 (48.7%) patients had complete remission, 12 (30.8%) had partial remission, and eight (20.5%) had stable disease in the intracranial lesions. Besides, there was no single case of complete remission, 21 (53.8%) had partial remission, and 18 (46.2%) had stable disease of the extracranial lesions. The median progression-free survival (PFS) of intracranial lesions and extracranial lesions was 18 and 12 months, respectively. The median overall survival (OS) was 26 months. The univariate analysis showed that graded prognostic assessment (P=0.006) and Karnofsky Performance Scale (P=0.045) were associated with intracranial progression-free survival (iPFS), while recursive partitioning analysis (P=0.049) was associated with OS of patients. Conclusion EGFR TKIs plus concomitant WBRT controlled intracranial lesions of lung cancer metastasis and significantly improved OS of patients. Further studies will be needed to confirm whether this combination treatment could be used as a standard therapy for EGFR-mutated NSCLC patients with BM. PMID:27022274

    Purpose: In this retrospective study, we report on outcomes and prognostic factors for patients treated with stereotactic radiosurgery (SRS) for breast cancer brain metastases. Methods and Materials: We identified 132 consecutive patients with breast cancer who were treated with SRS for brain metastases from January 2000 through June 2010. We retrospectively reviewed records of the 51 patients with adequate follow-up data who received SRS as part of the initial management of their brain metastases. Overall survival (OS) and time to central nervous system (CNS) progression from the date of SRS were calculated using the Kaplan-Meier method. Prognostic factors were evaluated using the Cox proportional hazards model. Results: Triple negative subtype was associated with CNS progression on univariate analysis (hazard ratio [HR] = 5.0, p = 0.008). On multivariate analysis, triple negative subtype (HR = 8.6, p = 0.001), Luminal B subtype (HR = 4.3, p = 0.03), and omission of whole-brain radiation therapy (HR = 3.7, p = 0.02) were associated with CNS progression. With respect to OS, Karnofsky Performance Status (KPS) {<=} 80% (HR = 2.0, p = 0.04) and progressive extracranial disease (HR = 3.1, p = 0.002) were significant on univariate analysis; KPS {<=} 80% (HR = 4.1, p = 0.0004), progressive extracranial disease (HR = 6.4, p < 0.0001), and triple negative subtype (HR = 2.9, p = 0.04) were significant on multivariate analysis. Although median survival times were consistent with those predicted by the breast cancer-specific Graded Prognostic Assessment (Breast-GPA) score, the addition of extracranial disease status further separated patient outcomes. Conclusions: Tumor subtype is associated with risk of CNS progression after SRS for breast cancer brain metastases. In addition to tumor subtype and KPS, which are incorporated into the Breast-GPA, progressive extracranial disease may be an important prognostic factor for OS.

    Breast cancer patients who achieve a pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) usually have a favourable prognosis. We report on a patient with early metastases to the brain after achieving pCR. The primary tumour was 7.0 cm in diameter with axillary lymph node metastases, hormone receptor-negative, human epidermal growth factor receptor-2-positive (3+), and histological grade 2 with 60% of cells positive for Ki-67. The patient underwent NAC followed by surgery, and achieved pCR. Five months after surgery, during adjuvant treatment with trastuzumab, she developed headache and dizziness. Brain imaging revealed multiple metastatic brain tumours. She received whole-brain radiotherapy followed by lapatinib and capecitabine therapy. At 7 months after surgery, she remains alive with a persistent mild headache. Physicians should be aware of the possibility of early brain metastases, and consider new treatment strategies to prevent brain metastases in high-risk patients who achieve pCR. PMID:24222158

    Objective To assess the use of palliative whole-brain radiotherapy (WBRT) in the treatment of brain metastases (BMs) and to evaluate the health-related quality of life (HRQOL) of these patients. Materials and methods We conducted a retrospective study of 46 patients with BMs who were treated with WBRT at the First Affiliated Hospital of Xi’an Jiaotong University between January 2013 and January 2015. External beam radiotherapy techniques were used to deliver 40 Gy in 20 fractions or 30 Gy in ten fractions with a 10 MV photon beam from a linear accelerator to the whole brain. Data were stored and analyzed using SPSS version 17.0. Results Of the 46 patients, the survival time of patients in our study was 10.8±0.55 months: 11.8±0.46 months in patients with WBRT, 11.75±1.00 in patients with WBRT + chemotherapy, and 3±0.79 months in patients with supportive care, respectively (P<0.01). The HRQOL scores of all the patients were 70±1.16 (before therapy) and 76.83±1.04 (after therapy) (P<0.01). The HRQOL scores of the patients with WBRT were 72.23±0.88 (before therapy) and 78.49±0.87 (after therapy) (P<0.01). There was no central nervous system toxicity; only two (4.3%) patients were found to have BM hemorrhage. Radiation necrosis happened in one patient (2.2%). Conclusion Effective treatment options for patients with BMs are important. WBRT was evaluated to ensure survival outcomes and QOL were enhanced after therapy for patients with BMs. PMID:26346192

    Sequencing of the epidermal growth factor receptor (EGFR) gene to identify mutations in lung adenocarcinomas is routine in clinical practice. The use of tyrosine kinase inhibitors (TKIs) has transformed the management of patients with brain metastases harboring EGFR mutations, with improved response rates (RR) and survival. We evaluate the role of concurrent TKI therapy and radiotherapy in this group of patients, considering this data in the context of emerging concepts in this advancing field. PMID:27186518

    We report two patients having recurrent breast cancer with brain metastases that was controlled well with a gamma knife radio-surgery. The patient is a 50-year-old woman. She underwent radical mastectomy for right breast cancer in September 1993. She suffered from multiple liver metastases in June 2000, so CEF therapy contained hepatic arterial infusion chemotherapy, and extended right lobectomy of the liver were performed in December 2001. Afterward, pleurodesis was carried out to the carcinomatous pleurisy. Then she underwent simple total hysterectomy and bilateral oophorectomy for torsion of the metastatic ovarian tumor. MRI study revealed brain metastases with a diameter of 1 cm in her right midbrain in April 2005, so a gamma knife radio-surgery was performed. After the radio-surgery, a weekly paclitaxel therapy followed by peroral chemotherapy with capecitabine was started, and she took the regimen continuously. Another patient is a 56-year-old woman. She underwent skin sparing mastectomy with axillary lymph node dissection for right breast cancer in November 2002. Metastases to the base of her skull were found in October 2004, so a gamma knife radio-surgery was carried out. After the radio-surgery, a weekly paclitaxel therapy with anastrozole was started. In both of the two patients, the metastatic brain tumors have not shown growth so far and are under good control as of March 2006. PMID:17212144

    Cancer of the brain and central nervous system (CNS) is the second most common of all pediatric cancers. Treatment of many of these cancers includes radiation therapy of which radiation induced cerebral necrosis (RICN) can be a severe and potentially devastating side effect. Risk factors for RICN include brain volume irradiated, the dose given per fraction and total dose. Thirteen pediatric patients were selected for this study to determine the difference in predicted risk of RICN when treating with volumetric modulated arc therapy (VMAT) compared to passively scattered proton therapy (PSPT) and intensity modulated proton therapy (IMPT). Plans were compared on the basis of dosimetric endpoints in the planned treatment volume (PTV) and brain and a radiobiological endpoint of RICN calculated using the Lyman-Kutcher-Burman probit model. Uncertainty tests were performed to determine if the predicted risk of necrosis was sensitive to positional errors, proton range errors and selection of risk models. Both PSPT and IMPT plans resulted in a significant increase in the maximum dose to the brain, a significant reduction in the total brain volume irradiated to low doses, and a significant lower predicted risk of necrosis compared with the VMAT plans. The findings of this study were upheld by the uncertainty analysis. PMID:25866999

    Brain metastases are a common complication of non-small cell lung cancer (NSCLC). Prognosis is poor and the effectiveness of whole brain radiotherapy (WBRT) is uncertain for patients with moderate performance status. Studies on WBRT effectiveness have thus far used outcome measures, such as survival, performance status and cognitive function. The aim of this study was to study what patients with recently diagnosed brain metastases from NSCLC want from their treatment. We carried out semistructured interviews with nine patients with brain metastases from NSCLC, for whom the benefit of WBRT is uncertain. Interpretative phenomenological analysis was used. Themes identified included quality versus quantity of life, factors contributing to quality of life (including family, mobility and normality), 'Go for it!' - the desire to try anything, the desire for a cure or 'magic wand', fear and other factors (including family in decision making, information or lack of information, relationship with professionals, experience of steroids and radiotherapy including adverse effects). Quality of life is important to patients, but many are keen to try any treatment which might prolong their life. Understanding patients' values regarding treatment and goals of treatment can help clinicians discuss these issues with patients and provide appropriate information and can aid selection of appropriate outcome measures.

    Breast cancer brain metastases (BCBM) are detected with increasing incidence. In order to detect potential genes involved in BCBM, we first screened for genes down-regulated by methylation in cell lines with site-specific metastatic ability. The expression of five genes, CADM1, SPARC, RECK, TNFAIP3 and CXCL14, which were also found down-regulated in gene expression profiling analyses of BCBM tissue samples, was verified by qRT-PCR in a larger patient cohort. CADM1 was chosen for further down-stream analyses. A higher incidence of CADM1 methylation, correlating with lower expression levels, was found in BCBM as compared to primary BC. Loss of CADM1 protein expression was detected most commonly among BCBM samples as well as among primary tumors with subsequent brain relapse. The prognostic role of CADM1 expression was finally verified in four large independent breast cancer cohorts (n=2136). Loss of CADM1 protein expression was associated with disease stage, lymph node status, and tumor size in primary BC. Furthermore, all analyses revealed a significant association between loss of CADM1 and shorter survival. In multivariate analyses, survival was significantly shorter among patients with CADM1-negative tumors. Loss of CADM1 expression is an independent prognostic factor especially associated with the development of brain metastases in breast cancer patients. PMID:24833255

    Background: In Asia, large-scale studies on anti-HER2 treatment in HER2-positive breast cancer patients with brain metastases are limited. We studied the treatment patterns of these patients in Asia to evaluate the impact of anti-HER2 treatment on the time to occurrence of brain metastases (TTBM) and survival after brain metastasis (BM). Methods: A retrospective study of HER2-positive breast cancer patients diagnosed with BM between January 2006 and December 2008 in six Asian countries was conducted. Demographics, tumour characteristics, treatment details, and events dates were collected from medical records. Results: Data from 280 patients were analysed. Before BM, 63% received anti-HER2 treatment. These patients had significantly longer TTBM than those without anti-HER2 treatment (median 33 vs 19 months; P<0.002). After BM, 93% received radiotherapy, 57% received chemotherapy, and 41% received anti-HER2 treatment (trastuzumab and/or lapatinib). Use of both anti-HER2 agents, primarily sequentially, after BM demonstrated the longest survival after BM and was associated with a significant survival benefit over no anti-HER2 treatment (median 26 vs 6 months; hazard ratio 0.37; 95% CI 0.19–0.72). Conclusion: Anti-HER2 treatment before BM was associated with longer TTBM. Anti-HER2 treatment after BM was associated with a survival benefit, especially when both trastuzumab and lapatinib were utilised. PMID:22918394

    Purpose: We tested the validity of 3 recently proposed prognostic indexes for breast cancer patients with brain metastases (METs) treated radiosurgically. The 3 indexes are Diagnosis-Specific Graded Prognostic Assessment (DS-GPA), New Breast Cancer (NBC)-Recursive Partitioning Analysis (RPA), and our index, sub-classification of RPA class II patients into 3 sub-classes (RPA class II-a, II-b and II-c) based on Karnofsky performance status, tumor number, original tumor status, and non-brain METs. Methods and Materials: This was an institutional review board-approved, retrospective cohort study using our database of 269 consecutive female breast cancer patients (mean age, 55 years; range, 26-86 years) who underwent Gamma Knife radiosurgery (GKRS) alone, without whole-brain radiation therapy, for brain METs during the 15-year period between 1996 and 2011. The Kaplan-Meier method was used to estimate the absolute risk of each event. Results: Kaplan-Meier plots of our patient series showed statistically significant survival differences among patients stratified into 3, 4, or 5 groups based on the 3 systems (P<.001). However, the mean survival time (MST) differences between some pairs of groups failed to reach statistical significance with all 3 systems. Thus, we attempted to regrade our 269 breast cancer patients into 3 groups by modifying our aforementioned index along with the original RPA class I and III, (ie, RPA I+II-a, II-b, and II-c+III). There were statistically significant MST differences among these 3 groups without overlap of 95% confidence intervals (CIs) between any 2 pairs of groups: 18.4 (95% CI = 14.0-29.5) months in I+II-a, 9.2 in II-b (95% CI = 6.8-12.9, P<.001 vs I+II-a) and 5.0 in II-c+III (95% CI = 4.2-6.8, P<.001 vs II-b). Conclusions: As none of the new grading systems, DS-GPS, BC-RPA and our system, was applicable to our set of radiosurgically treated patients for comparing survivals after GKRS, we slightly modified our system for breast cancer

    Patients with HER2-positive breast cancer and brain metastases have limited treatment options, and, as a result of their poor performance status and worse prognosis, they are underrepresented in clinical trials. Not surprisingly, these patients may not be fit enough to receive any active treatment and are offered supportive therapy. BRCA2 mutations are reported to be rarely associated with HER2-overexpressing advanced breast cancer and even more rarely with brain metastases at diagnosis. We report on a BRCA2-positive breast cancer patient with metastatic disease in multiple sites, including the brain, and poor performance status who exhibited an extraordinary clinical and imaging response to the novel anti-HER2 therapy pertuzumab after multiple lines of therapy including anti-HER2 targeting. To our knowledge, the clinicopathologic and therapeutic characteristics of this patient point to a unique case and an urgent need for further investigation of pertuzumab in patients with brain metastases.

    Central nervous system or brain metastases traditionally occur in 10-16% of metastatic breast cancer patients and are associated with a dismal prognosis. The development of brain metastases has been associated with young age, and tumors that are estrogen receptor negative, Her-2+ or of the basal phenotype. Treatment typically includes whole brain irradiation, or either stereotactic radiosurgery or surgery with whole brain radiation, resulting in an approximately 20% one year survival. The blood-brain barrier is a formidable obstacle to the delivery of chemotherapeutics to the brain. Mouse experimental metastasis model systems have been developed for brain metastasis using selected sublines of human MDA-MB-231 breast carcinoma cells. Using micron sized iron particles and MRI imaging, the fate of MDA-MB-231BR cells has been mapped: Approximately 2% of injected cells form larger macroscopic metastases, while 5% of cells remain as dormant cells in the brain. New therapies with permeability for the blood-brain barrier are needed to counteract both types of tumor cells. PMID:17473372

    Purpose: The aim of the study is to evaluate disease-free survival, survival from the detection of brain metastases, overall survival, and cause of death in patients with occult brain metastases (Group I) vs. patients with symptomatic brain metastases (Group II). Methods and Materials: In 80 HER2-positive breast cancer patients, treated with trastuzumab and cytostatic agents for metastatic disease, magnetic resonance imaging screening of the brain was performed, and in 29 patients (36%) occult brain metastasis was detected (Group I). Whole-brain radiotherapy was delivered to Group I. This first group was compared with 52 patients who had symptomatic brain metastases (Group II) and was treated the same way, at the same clinic, during the same time period. Results: Median disease-free survival was 17 months in Group I and 19.9 months in Group II (p = 0.58). The median time interval between the dissemination of the disease and the detection of occult or symptomatic brain metastases was 9 and 15 months, respectively (p = 0.11). When the brain metastases were detected, the median survival was 9 and 8.78 months, respectively (p = 0.80). The median overall survival was 53 and 51 months, respectively (p = 0.94). In the group with occult brain metastases (Group I) 16% of patients died because of progression within the brain. In the group with symptomatic brain metastases (Group II) the rate of cerebral death was 48% (p = 0.009). Conclusions: Whole-brain radiotherapy of occult brain metastases in HER2-positive breast cancer patients with visceral dissemination produces a three-fold decrease in cerebral deaths but does not prolong survival.

    Purpose: The diagnosis-specific Graded Prognostic Assessment (GPA) was published to clarify prognosis for patients with brain metastases. This study refines the existing Breast-GPA by analyzing a larger cohort and tumor subtype. Methods and Materials: A multi-institutional retrospective database of 400 breast cancer patients treated for newly diagnosed brain metastases was generated. Prognostic factors significant for survival were analyzed by multivariate Cox regression and recursive partitioning analysis (RPA). Factors were weighted by the magnitude of their regression coefficients to define the GPA index. Results: Significant prognostic factors by multivariate Cox regression and RPA were Karnofsky performance status (KPS), HER2, ER/PR status, and the interaction between ER/PR and HER2. RPA showed age was significant for patients with KPS 60 to 80. The median survival time (MST) overall was 13.8 months, and for GPA scores of 0 to 1.0, 1.5 to 2.0, 2.5 to 3.0, and 3.5 to 4.0 were 3.4 (n = 23), 7.7 (n = 104), 15.1 (n = 140), and 25.3 (n = 133) months, respectively (p < 0.0001). Among HER2-negative patients, being ER/PR positive improved MST from 6.4 to 9.7 months, whereas in HER2-positive patients, being ER/PR positive improved MST from 17.9 to 20.7 months. The log-rank statistic (predictive power) was 110 for the Breast-GPA vs. 55 for tumor subtype. Conclusions: The Breast-GPA documents wide variation in prognosis and shows clear separation between subgroups of patients with breast cancer and brain metastases. This tool will aid clinical decision making and stratification in clinical trials. These data confirm the effect of tumor subtype on survival and show the Breast-GPA offers significantly more predictive power than the tumor subtype alone.

    Purpose: Traditional radiation therapy of cancer is heavily dependent on CT. CT provides excellent depiction of the bones but lacks good soft tissue contrast, which makes contouring difficult. Often, MRIs are fused with CT to take advantage of its superior soft tissue contrast. Such an approach has drawbacks. It is desirable to perform treatment simulation entirely based on MRI. To achieve MR-based simulation for radiation therapy, bone imaging is an important challenge because of the low MR signal intensity from bone due to its ultra-short T2 and T1, which presents difficulty for both dose calculation and patient setup in terms of digitally reconstructed radiograph (DRR) generation. Current solutions will either require manual bone contouring or multiple MR scans. We present a technique to generate DRR using MRI with an Ultra Short Echo Time (UTE) sequence which is applicable to both OBI and ExacTrac 2D patient setup. Methods: Seven brain cancer patients were scanned at 1.5 Tesla using a radial UTE sequence. The sequence acquires two images at two different echo times. The two images were processed using in-house software. The resultant bone images were subsequently loaded into commercial systems to generate DRRs. Simulation and patient clinical on-board images were used to evaluate 2D patient setup with MRI-DRRs. Results: The majority bones are well visualized in all patients. The fused image of patient CT with the MR bone image demonstrates the accuracy of automatic bone identification using our technique. The generated DRR is of good quality. Accuracy of 2D patient setup by using MRI-DRR is comparable to CT-based 2D patient setup. Conclusion: This study shows the potential of DRR generation with single MR sequence. Further work will be needed on MR sequence development and post-processing procedure to achieve robust MR bone imaging for other human sites in addition to brain.

    Objective: This pilot study was designed to describe changes in spiritual well-being (SWB), spiritual coping, and quality of life (QOL) in patients with brain cancer or other neurodegenerative diseases participating in a chaplain-led spiritual life review interview and development of a spiritual legacy document (SLD). Methods: Eligible participants were enrolled and completed baseline questionnaires. They were interviewed by a board-certified chaplain about spiritual influences, beliefs, practices, values, and spiritual struggles. An SLD was prepared for each participant, and one month follow-up questionnaires were completed. Two cases are summarized, and spiritual development themes are illustrated within a spiritual development framework. Results: A total of 27 patients completed baseline questionnaires and the interview; 24 completed the SLD, and 15 completed the follow-up questionnaire. Increases in SWB, religious coping, and QOL were detected. The majority maintained the highest (best) scores of negative religious coping, demonstrating minimal spiritual struggle. Conclusions: Despite the challenges of brain cancers and other neurodegenerative diseases, participants demonstrated improvements in SWB, positive religious coping, and QOL. Patient comments indicate that benefit is related to the opportunity to reflect on and integrate spiritual experiences and to preserve them for others. Research with a larger, more diverse sample is needed, as well as clinical applications for those too vulnerable to participate in longitudinal follow-up. PMID:25973267

    2013-01-01

    Malignant brain cancer treatment is limited by a number of barriers, including the blood–brain barrier, transport within the brain interstitium, difficulties in delivering therapeutics specifically to tumor cells, the highly invasive quality of gliomas and drug resistance. As a result, the prognosis for patients with high-grade gliomas is poor and has improved little in recent years. Nanomedicine approaches have been developed in the laboratory, with some technologies being translated to the clinic, in order to address these needs. This review discusses the obstacles to effective treatment that are currently faced in the field, as well as various nanomedicine techniques that have been used or are being explored to overcome them, with a focus on liposomal and polymeric nanoparticles.

    The brain has long been considered an immune-privileged site precluding potent immune responses. Nevertheless, because of the failure of conventional anti-cancer treatments to achieve sustained control of intracranial neoplasms, immunotherapy has been considered as a promising strategy for decades. However, several efforts aimed at exploiting the immune system as a therapeutic weapon were largely unsuccessful. The situation only changed with the introduction of the checkpoint inhibitors, which target immune cell receptors that interfere with the activation of immune effector cells. Following the observation of striking effects of drugs that target CTLA-4 or PD-1 against melanoma and other tumor entities, it was recognized that these drugs may also be active against metastatic tumor lesions in the brain. Their therapeutic activity against primary brain tumors is currently being investigated within clinical trials. In parallel, other immunotherapeutics such as peptide vaccines are at an advanced stage of clinical development. Further immunotherapeutic strategies currently under investigation comprise adoptive immune cell transfer as well as inhibitors of metabolic pathways involved in the local immunosuppression frequently found in brain tumors. Thus, the ongoing implementation of immunotherapeutic concepts into clinical routine may represent a powerful addition to the therapeutic arsenal against various brain tumors. PMID:27260656

    Objective The tumor-to-brain communication has been emphasized by recent converging evidences. This study aimed to compare the difference of brain glucose metabolism between patients with non-small cell lung cancer (NSCLC) and control subjects. Methods NSCLC patients prior to oncotherapy and control subjects without malignancy confirmed by 6 months follow-up were collected and underwent the resting state 18F-fluoro-D-glucose (FDG) PET/CT. Normalized FDG metabolism was calculated by a signal intensity ratio of each brain region to whole brain. Brain glucose metabolism was compared between NSCLC patients and control group using two samples t-test and multivariate test by statistical parametric maps (SPM) software. Results Compared with the control subjects (n = 76), both brain glucose hyper- and hypometabolism regions with significant statistical differences (P<0.01) were found in the NSCLC patients (n = 83). The hypermetabolism regions (bilateral insula, putamen, pallidum, thalamus, hippocampus and amygdala, the right side of cerebellum, orbital part of right inferior frontal gyrus and vermis) were component parts of visceral to brain signal transduction pathways, and the hypometabolism regions (the left superior parietal lobule, bilateral inferior parietal lobule and left fusiform gyrus) lied in dorsal attention network and visuospatial function areas. Conclusions The changes of brain glucose metabolism exist in NSCLC patients prior to oncotherapy, which might be attributed to lung-cancer related visceral sympathetic activation and decrease of dorsal attention network function.

    Brain metastases are not only the most common intracranial neoplasm in adults but also very prevalent in patients with lung cancer. Patients have been grouped into different classes based on the presence of prognostic factors such as control of the primary tumor, functional performance status, age, and number of brain metastases. Patients with good prognosis may benefit from more aggressive treatment because of the potential for prolonged survival for some of them. In this review, we will comprehensively discuss the therapeutic options for treating brain metastases, which arise mostly from a lung cancer primary. In particular, we will focus on the patient selection for combined modality treatment of brain metastases, such as surgical resection or stereotactic radiosurgery (SRS) combined with whole brain irradiation; the use of radiosensitizers; and the neurocognitive deficits after whole brain irradiation with or without SRS. The benefit of prophylactic cranial irradiation (PCI) and its potentially associated neuro-toxicity for both small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) are also discussed, along with the combined treatment of intrathoracic primary disease and solitary brain metastasis. The roles of SRS to the surgical bed, fractionated stereotactic radiotherapy, WBRT with an integrated boost to the gross brain metastases, as well as combining WBRT with epidermal growth factor receptor (EGFR) inhibitors, are explored as well.

    We present the case of a 55-year-old-woman who was diagnosed with left breast cancer, and underwent a left mastectomy and left axillary lymph node resection. The histopathological examination indicated scirrhous carcinoma and lesser papillotubular carcinoma[estrogen receptor-negative (ER-), progesterone receptor-negative(PgR-), and human epidermal growth factor receptor 2-positive, grade 3 (HER2, 3+)] with lymph node metastases. Adjuvant chemotherapy consisting of epirubicin and cyclophosphamide (EC) followed by paclitaxel was administered. During the therapy, the patient noticed a mass on her left chest wall. It was diagnosed as a locally recurrent tumor. A computed tomography (CT) scan indicated supraclavicular lymph node metastasis. The patient underwent radiotherapy and was administered chemotherapy with TS-1 and trastuzumab. Brain metastases were found 24 months postoperatively, and the patient underwent surgery and wholebrain radiotherapy. After these, systemic capecitabine and trastuzumab chemotherapy was administered. The therapy was subsequently changed to capecitabine and lapatinib. There have been no subsequent metastatic tumors, and good control has been achieved for a long time after the detection of brain metastases. PMID:25731368

    Purpose To analyze the clinical features and prognostic factors associated with the survival of patients with a very rare occurrence of brain metastasis (BM) from differentiated thyroid cancer (DTC). Methods and Materials A total of 37 patients with DTC who were diagnosed with BM between 1995 and 2014 were included. We reviewed the clinical characteristics, treatment modalities, and image findings of BM. Factors associated with survival were evaluated, and the patients were divided into three prognostic groups (Groups A, B, and C) for comparative analysis. Results The median age at BM was 63 years, and the median time from initial thyroid cancer diagnosis to BM was 3.8 years. The median survival and the 1-year actuarial survival rate after BM were 8.8 months and 47%, respectively. According to univariate and multivariate analyses, four good prognostic factors (GPFs) were identified including age ≤ 60 years, PS ≤ ECOG 2, ≤ 3 BM sites, and without extracranial metastasis prior to BM. Three prognostic groups were designed based on age and number of remaining GPFs: patients ≤ 60 years of age with at least 2 GPFs (Group A) had the most favorable prognosis with a median survival of 32.8 months; patients ≤ 60 years of age with fewer than 2 GPFs and those > 60 years of age with at least 2 GPFs (Group B) had an intermediate prognosis with a median survival of 9.4 months; and patients > 60 years of age with fewer than 2 GPFs (Group C) had the least favorable prognosis with a median survival of 1.5 months. Conclusions The survival of patients with BM form DTC differed among the prognostic groups based on the total number of good prognostic factors. PMID:27128487

    Background Lung cancers account for the majority of brain metastases which pose major therapeutic challenges. Biomarkers prognosticating for the development of brain metastases in patients with non-small cell lung cancers (NSCLC) may improve personalized care. Six serum proteomic biomarkers were previously investigated at Memorial Sloan Kettering but their associations with brain metastases were unknown. Methods Serum NSE, CYFRA 21–1, ProGRP, SCC-Ag, TIMP1, and HE4 by ELISA-based proteomic assays were prospectively collected from consecutive patients with stage IV NSCLC. Pre-treatment serum biomarker levels as well as age, histology, and epidermal growth factor receptor (EGFR) mutation status were evaluated for association with the baseline presence of brain metastases using logistic regression and multivariable analysis. For patients without brain metastases at baseline, the cumulative incidence of subsequent brain metastases were compared according to baseline biomarkers and clinical factors using Gray’s test. Results A total of 118 patients were enrolled, 31 (26%; 95% CI 0.19–0.35) had brain metastases at baseline and a further 26 (22%; 95% CI 0.15–0.30) developed brain metastases subsequently. Pre-treatment serum biomarker levels were available in 104 patients. There was no significant association between the six serum biomarkers and the baseline presence or subsequent development of brain metastases. Age younger than 65 years was the only clinical factor significantly associated with brain metastasis at baseline (OR 3.00; 95% CI 1.22–7.34, P = 0.02) by multivariable analysis. A trend toward increased cumulative incidence of subsequent brain metastases was observed in patients with EGFR mutation (p = 0.2), but this was not statistically significant possibly due to small sample size. Conclusions Serum NSE, CYFRA 21–1, Pro-GRP, SCC-Ag, TIMP1, and HE4 are not significantly associated with brain metastases. Our methods taking into account follow-up time

    Background Neuro-oncologists are familiar with primary brain tumors, intracerebral metastases meningeal carcinomatosis and extracerebral intracranial tumors as meningeoma. For these conditions, and also some other rare tumor entities several treatment options exist. Cancer can also involve structures around the brain as the dura, the base of the skull, the cavities of the skull and tissue around the bony skull, the skin, the tissue of the neck. and either compress, invade or spread in the central or peripheral nervous system. Methods A systematic literature research was conducted determining symptoms and signs, tumor sites of nerve invasion, tumor types, diagnostic techniques, mechanisms of nerve invasion, and important differential diagnosis. Additional cases from own experience were added for illustration. Results The mechanisms of tumor invasion of cranial nerves is heterogenous and not only involves several types of invasion, but also spread along the cranial nerves in antero- and retrograde fashion and even spread into different nerve territories via anastomosis. In addition the concept of angiosomas may have an influence on the spread of metastases. Conclusion In addition to the well described tumor spread in meningeal carcinomatosis and base of the skull metastases, dural spread, lesions of the bony skull, the cavities of the skull and skin of the face and tissue of the neck region need to be considered, and have an impact on therapeutic decisions.

    Quality of life (QoL) is an increasingly important outcome measure in medicine. Health, in fact, is not only based on functional status but also on psychological and social well being. Since QoL is related to the patient's perception of their position in life in relation to their goals, expectations, standards and concerns, the way in which the medical context is experienced may be critical. We then hypothesised that self-perceived QoL may be linked to unmet needs in information management and decision involvement. To analyse this hypothesis, we conducted a quantitative study on 84 consecutive patients with a diagnosis of primary high-grade glioma. The functional assessment of cancer therapy-Brain (FACT-Br) scales, the hospital anxiety and depression (HAD) scale and the need evaluation questionnaire (NEQ) questionnaire were used, in order to measure quality-of-life dimension, mood and unmet needs. Patients were classified as having no need (cluster 1), a moderate need (cluster 2) or a high need (cluster 3) to be more involved in the clinical process.Our data confirmed previous studies in other clinical areas, showing that shared decision might contribute to a better adaptation process to the illness [1]. In fact, patients in cluster 1 showed a significant better self-perceived QoL, despite the lack of clinical differences between clusters. The study showed that patients satisfied with respect to decisional involvement seem to be able to better cope with their disease. Finally, the study suggests the need for a more attuned decision-making process in approaching clinical decisions. Physicians need to better understand patient preferences related to information and decision sharing. PMID:22276038

    Brain metastasis from colorectal cancer is infrequent and carries a poor prognosis. Herein, we present a patient alive 10 years after the identification of a first brain metastasis from sigmoid colon cancer. A 39-year-old woman underwent sigmoidectomy for sigmoid colon cancer during an emergency operation for pelvic peritonitis. The pathological finding was moderately differentiated adenocarcinoma. Eleven months after the sigmoidectomy, a metastatic lesion was identified in the left ovary. Despite local radiotherapy followed by chemotherapy, the left ovarian lesion grew, so resection of the uterus and bilateral ovaries was performed. Adjuvant chemotherapy with tegafur-uracil (UFT)/calcium folinate (leucovorin, LV) was initiated. Seven months after resection of the ovarian lesion, brain metastases appeared in the bilateral frontal lobes and were treated with stereotactic Gamma Knife radiosurgery. Cervical and mediastinal lymph node metastases were also diagnosed, and irradiation of these lesions was performed. After radiotherapy, 10 courses of oxaliplatin and infused fluorouracil plus leucovorin (FOLFOX) were administered. During FOLFOX administration, recurrent left frontal lobe brain metastasis was diagnosed and treated with stereotactic Gamma Knife radiosurgery. In this case, the brain metastases were well treated with stereotactic Gamma Knife radiosurgery, and the systemic disease arising from sigmoid colon cancer has been kept under control with chemotherapies, surgical resection, and radiotherapy.

    Purpose: To explore whether gender and race influence survival in non-small-cell lung cancer (NSCLC) in patients with brain metastases, using our large single-institution brain tumor database and the Radiation Therapy Oncology Group recursive partitioning analysis (RPA) brain metastases classification. Methods and materials: A retrospective review of a single-institution brain metastasis database for the interval January 1982 to September 2004 yielded 835 NSCLC patients with brain metastases for analysis. Patient subsets based on combinations of gender, race, and RPA class were then analyzed for survival differences. Results: Median follow-up was 5.4 months (range, 0-122.9 months). There were 485 male patients (M) (58.4%) and 346 female patients (F) (41.6%). Of the 828 evaluable patients (99%), 143 (17%) were black/African American (B) and 685 (83%) were white/Caucasian (W). Median survival time (MST) from time of brain metastasis diagnosis for all patients was 5.8 months. Median survival time by gender (F vs. M) and race (W vs. B) was 6.3 months vs. 5.5 months (p = 0.013) and 6.0 months vs. 5.2 months (p = 0.08), respectively. For patients stratified by RPA class, gender, and race, MST significantly favored BFs over BMs in Class II: 11.2 months vs. 4.6 months (p = 0.021). On multivariable analysis, significant variables were gender (p = 0.041, relative risk [RR] 0.83) and RPA class (p < 0.0001, RR 0.28 for I vs. III; p < 0.0001, RR 0.51 for II vs. III) but not race. Conclusions: Gender significantly influences NSCLC brain metastasis survival. Race trended to significance in overall survival but was not significant on multivariable analysis. Multivariable analysis identified gender and RPA classification as significant variables with respect to survival.

    Purpose: To report the outcome of patients with synchronous, solitary brain metastasis from non-small-cell lung cancer (NSCLC) treated with gamma knife stereotactic radiosurgery (GKSRS). Patients and Methods: Forty-two patients diagnosed with synchronous, solitary brain metastasis from NSCLC were treated with GKSRS between 1993 and 2006. The median Karnofsky performance status (KPS) was 90. Patients had thoracic Stage I-III disease (American Joint Committee on Cancer 2002 guidelines). Definitive thoracic therapy was delivered to 26/42 (62%) patients; 9 patients underwent chemotherapy and radiation, 12 patients had surgical resection, and 5 patients underwent preoperative chemoradiation and surgical resection. Results: The median overall survival (OS) was 18 months. The 1-, 2-, and 5-year actuarial OS rates were 71.3%, 34.1%, and 21%, respectively. For patients who underwent definitive thoracic therapy, the median OS was 26.4 months compared with 13.1 months for those who had nondefinitive therapy, and the 5-year actuarial OS was 34.6% vs. 0% (p < 0.0001). Median OS was significantly longer for patients with a KPS {>=}90 vs. KPS < 90 (27.8 months vs. 13.1 months, p < 0.0001). The prognostic factors significant on multivariate analysis were definitive thoracic therapy (p = 0.020) and KPS (p = 0.001). Conclusions: This is one of the largest series of patients diagnosed with synchronous, solitary brain metastasis from NSCLC treated with GKSRS. Definitive thoracic therapy and KPS significantly impacted OS. The 5-year OS of 21% demonstrates the potential for long-term survival in patients treated with GKSRS; therefore, patients with good KPS should be considered for definitive thoracic therapy.

    Purpose: To determine the efficacy of motexafin gadolinium (MGd) in combination with whole brain radiotherapy (WBRT) for the treatment of brain metastases from non-small-cell lung cancer. Methods and Materials: In an international, randomized, Phase III study, patients with brain metastases from non-small-cell lung cancer were randomized to WBRT with or without MGd. The primary endpoint was the interval to neurologic progression, determined by a centralized Events Review Committee who was unaware of the treatment the patients had received. Results: Of 554 patients, 275 were randomized to WBRT and 279 to WBRT+MGd. Treatment with MGd was well tolerated, and 92% of the intended doses were administered. The most common MGd-related Grade 3+ adverse events included liver function abnormalities (5.5%), asthenia (4.0%), and hypertension (4%). MGd improved the interval to neurologic progression compared with WBRT alone (15 vs. 10 months; p = 0.12, hazard ratio [HR] = 0.78) and the interval to neurocognitive progression (p = 0.057, HR = 0.78). The WBRT patients required more salvage brain surgery or radiosurgery than did the WBRT+MGd patients (54 vs. 25 salvage procedures, p < 0.001). A statistically significant interaction between the geographic region and MGd treatment effect (which was in the prespecified analysis plan) and between treatment delay and MGd treatment effect was found. In North American patients, where treatment was more prompt, a statistically significant prolongation of the interval to neurologic progression, from 8.8 months for WBRT to 24.2 months for WBRT+MGd (p = 0.004, HR = 0.53), and the interval to neurocognitive progression (p = 0.06, HR = 0.73) were observed. Conclusion: In the intent-to-treat analysis, MGd exhibited a favorable trend in neurologic outcomes. MGd significantly prolonged the interval to neurologic progression in non-small-cell lung cancer patients with brain metastases receiving prompt WBRT. The toxicity was acceptable.

    Brain metastasis (BM) is the common complication of non-small cell lung cancer (NSCLC) with a poor prognosis and dismal survival rate. This update meta-analysis aimed to derive a more precise estimation of radiotherapy plus epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in NSCLC patients with BM. PubMed, EMBASE, Web of Science, Google Scholar, and Cochrane Library were searched to identify any relevant publications. After screening the literature and undertaking quality assessment and data extraction, the meta-analysis was performed using STATA Version 12.0. In total, 15 studies involving 1552 participants were included. The results indicated that radiotherapy plus EGFR TKIs was more effective at improving response rate and disease control rate (DCR) (risk ratio (RR) = 1.48, 95% confidence interval [CI]: 1.12-1.96, P = 0.005; RR = 1.29, 95% CI: 1.02-1.60, P = 0.035; respectively) than radiotherapy alone or plus chemotherapy. Moreover, radiotherapy plus EGFR TKIs significantly prolonged the time to central nervous system progression (CNS-TTP) (HR = 0.56, 95% CI [0.33, 0.80]; P = 0.000) and median overall survival (OS) (HR = 0.58, 95% CI [0.42, 0.74]; P = 0.000) but significantly increased adverse events (any grade) (RR = 1.25, 95% CI [1.01, 1.57]; P = 0.009), especially rash and dry skin. These results suggested that radiotherapy plus EGFR TKIs produced superior response rate and DCR and markedly prolonged the CNS-TTP and OS of NSCLC patients with BM. However, combined groups had the higher rate of incidence of overall adverse effects, especially rash and dry skin. PMID:26990668

    Purpose: To investigate whether prophylactic cranial irradiation (PCI) has a role in the management of patients with non-small-cell lung cancer (NSCLC) treated with curative intent. Methods and Materials: A search strategy was designed to identify randomized controlled trials (RCTs) comparing PCI with no PCI in NSCLC patients treated with curative intent. The electronic databases MEDLINE, EMBASE, LILACS, and Cancerlit were searched, along with relevant journals, books, and review articles to identify potentially eligible trials. Four RCTs were identified and reviewed. A total of 951 patients were randomized in these RCTs, of whom 833 were evaluable and reported. Forty-two patients with small-cell lung cancer were excluded, leaving 791 patients in total. Because of the small patient numbers and trial heterogeneity, no meta-analysis was attempted. Results: Prophylactic cranial irradiation did significantly reduce the incidence of brain metastases in three trials. No trial reported a survival advantage with PCI over observation. Toxicity data were poorly collected and no quality of life assessments were carried out in any trial. Conclusion: Prophylactic cranial irradiation may reduce the incidence of brain metastases, but there is no evidence of a survival benefit. It was not possible to evaluate whether any radiotherapy regimen is superior, and the effect of PCI on quality of life is not known. There is insufficient evidence to support the use of PCI in clinical practice. Where possible, patients should be offered entry into a clinical trial.

    Approximately one-third of patients with advanced, HER2-positive breast cancer develop brain metastases. A significant proportion of women experience central nervous system (CNS) progression after standard radiation therapy. The optimal treatment in the refractory setting is undefined. This study evaluated the toxicity and efficacy of lapatinib in combination with chemotherapy among patients with HER2-positive, progressive brain metastases. Patients with HER2-positive breast cancer with progressive brain metastases after trastuzumab and cranial radiotherapy were included. The primary endpoint was CNS objective response, defined as a ≥ 50% volumetric reduction of CNS lesion(s) in the absence of new or progressive CNS or non-CNS lesions, or increasing steroid requirements. The study was closed early after 22 of a planned 110 patients were enrolled due to excess toxicity and lack of efficacy in the lapatinib plus topotecan arm. The objective response rate (ORR) in the lapatinib plus capecitabine arm was 38% (exact 95% confidence interval [CI] 13.9-68.4). No responses were observed in the lapatinib plus topotecan arm. Although the study was stopped prior to full enrollment, some promising indications of CNS activity were noted for lapatinib plus capecitabine. The combination of lapatinib plus topotecan was not active and was associated with excess toxicity. PMID:21706359

    Large-scale genomic characterization of squamous cell lung cancers (SQCLC) has revealed several putative oncogenic drivers. There are, however, little data to suggest that these alterations have clinical relevance. We performed comprehensive genomic profiling of 79 stage IV SQCLCs (including next-generation sequencing) and analyzed differences in the clinical characteristics of two major SQCLC subtypes: FGFR1 amplified and PI3K aberrant. Patients with PI3K aberrant tumors had aggressive disease marked by worse survival (median OS 8.6 vs. 19.1 mo, p<0.001), higher metastatic burden (>3 organs 18% vs. 3%, p=0.025), and greater incidence of brain metastases (27% vs. 0% in others, p<0.001). We performed whole-exome and RNA sequencing on paired brain metastases and primary lung cancers to elucidate the metastatic process to brain. SQCLC primaries that gave rise to brain metastases exhibited truncal PTEN loss. SQCLC brain metastases exhibited a high degree of genetic heterogeneity and evidence of clonal differences between their primary sites. PMID:25929848

    This systematic review aims to improve understanding of the burden of disease associated with brain metastases from non-small-cell lung cancer (NSCLC) in terms of survival, quality of life (QoL) and economic impact. PubMed/MEDLINE, Cochrane collaboration and EMBASE databases were searched for articles published in English from 2000 to 2014. Of 3288 abstracts retrieved, 3156 were eliminated without a full-text review. Of the 132 articles that received a full-text review, a final set of 93 articles was included in an initial literature analysis. In order to homogenize the patient populations evaluated, we included entries that were either entirely composed of NSCLC patients or that had >50% of NSCLC patients in the total study population. From the studies identified in this systematic review, median OS and PFS varied based on the type of treatment received, although whole-brain radiotherapy (WBRT) was associated with the shortest OS and PFS durations. Regimens incorporating targeted therapy in molecularly selected patients were associated with the longest OS and PFS durations. QoL findings varied among studies, generally WBRT resulted in stable or worsening QoL scores rather than improvements. Healthcare costs were increased following diagnosis of brain metastases regardless of treatment. The findings from this review highlight the need for more effective treatments of brain metastases from NSCLC that improve survival function, QoL and potentially decrease costs. PMID:27019457

    This report describes a case of ab initio metastatic HER2-positive breast cancer in a very young patient. The onset of breast cancer at such a young age is uncommon and could delay the diagnosis with unquestionable impact on the prognosis. Unfortunately, the patient experienced cerebral progression during first-line treatment. Indeed, brain metastases occur in about one-third of HER2-positive metastatic breast cancer patients during trastuzumab-based treatment. The small molecule lapatinib is active in established cerebral disease, and we report a complete brain response longer than expected, thanks to a well-tolerated, orally administered combination of lapatinib and capecitabine.

    Objective Several papers have reported elevated plasma levels of natriuretic peptides in patients with a previous diagnosis of cancer. We have explored whether N-terminal pro-brain natriuretic peptide (NT-proBNP) plasma levels predict a future diagnosis of cancer in patients with coronary artery disease (CAD). Methods We studied 699 patients with CAD free of cancer. At baseline, NT-proBNP, galectin-3, monocyte chemoattractant protein-1, soluble tumor necrosis factor-like weak inducer of apoptosis, high-sensitivity C-reactive protein, and high-sensitivity cardiac troponin I plasma levels were assessed. The primary outcome was new cancer diagnosis. The secondary outcome was cancer diagnosis, heart failure requiring hospitalization, or death. Results After 2.15±0.98 years of follow-up, 24 patients developed cancer. They were older (68.5 [61.5, 75.8] vs 60.0 [52.0, 72.0] years; p=0.011), had higher NT-proBNP (302.0 [134.8, 919.8] vs 165.5 [87.4, 407.5] pg/ml; p=0.040) and high-sensitivity C-reactive protein (3.27 [1.33, 5.94] vs 1.92 [0.83, 4.00] mg/L; p=0.030), and lower triglyceride (92.5 [70.5, 132.8] vs 112.0 [82.0, 157.0] mg/dl; p=0.044) plasma levels than those without cancer. NT-proBNP (Hazard Ratio [HR]=1.030; 95% Confidence Interval [CI]=1.008-1.053; p=0.007) and triglyceride levels (HR=0.987; 95%CI=0.975-0.998; p=0.024) were independent predictors of a new cancer diagnosis (multivariate Cox regression analysis). When patients in whom the suspicion of cancer appeared in the first one-hundred days after blood extraction were excluded, NT-proBNP was the only predictor of cancer (HR=1.061; 95%CI=1.034-1.088; p<0.001). NT-proBNP was an independent predictor of cancer, heart failure, or death (HR=1.038; 95%CI=1.023-1.052; p<0.001) along with age, and use of insulin and acenocumarol. Conclusions NT-proBNP is an independent predictor of malignancies in patients with CAD. New studies in large populations are needed to confirm these findings. PMID:26046344

    Few data are currently available regarding the efficacy and safety of T-DM1 in breast cancer (BC) patients with unselected brain metastases (BM), since most clinical trials have excluded BM patients or have only included highly selected patients. HER2 + BC patients with BM treated with T-DM1 in 5 French centers were included in this retrospective study. Clinical management was performed according to the product guidelines. Efficacy was evaluated recording tumor response rates, progression-free (PFS) and overall survival, treatment compliance, and safety. Thirty nine patients received T-DM1, among whom 82 % presented with concomitant extra-cerebral disease. Median number of previous metastatic chemotherapy and HER2-directed targeted therapy regimens was 2 (range 0-8) and 1 (0-7), respectively. Thirty six patients had received BM loco-regional treatment (72 % whole-brain radiation therapy). After a median follow-up of 8.1 months (1.4-39.6), 24 patients had progressed (first site of progression: brain 14; meningeal 2; outside of the central nervous system 5; both intra- and extra-cerebral 3), 12 patients had died (disease progression), and 27 patients were still alive. Median number of T-DM1 cycles was 8 (1-43). There were 17 partial responses (44 %) and 6 patients achieved disease stabilization (59 % clinical benefit rate). Median PFS was 6.1 months (95 %CI 5.2-18.3), with one- and two-year PFS rates of 33 and 17 %, respectively. Treatment was well tolerated, without unexpected toxicities, treatment delay, or dose reduction. In this retrospective study, T-DM1 appeared to be an effective and well-tolerated therapeutic option in unselected HER2 + BC patients with BM. These findings require a prospective validation.

    We describe the delayed development of intracranial abscesses following emergent treatment with a covered stent-graft for carotid blowout syndrome (CBS) in a patient with head and neck cancer. The patient presented with hemoptysis and frank arterial bleeding through the tracheostomy site. A self-expandable stent-graft was deployed across a small pseudoaneurysm arising from the right common carotid artery (RCCA) and resulted in immediate hemostasis. Three months later, the patient suffered a recurrent hemorrhage. CT of the neck demonstrated periluminal fluid around the caudal aspect of the stent-graft with intraluminal thrombus and a small pseudoaneurysm. Subsequently, the patient underwent a balloon test occlusion study and endovascular sacrifice of the RCCA and right internal carotid artery. MRI of the brain demonstrated at least four ring-enhancing lesions within the right cerebral hemisphere consistent with intracranial abscesses that resolved with broad-spectrum antibiotic coverage.

    Systemic metastases from ovarian carcinoma are frequent, but they seldom affect the central nervous system. We present here the case of a patient treated for an ovarian cancer by surgery and chemotherapy. Three months after the end of chemotherapy, the patient developed cerebral metastases from ovarian carcinoma (CMOC) treated by iterative surgery and and whole brain irradiation. As the frequency of solitary cerebral metastasis of ovarian cancer is higher than with other cancers, it is likely that they behave slightly differently. Literature analysis reveals an increase in the incidence of CMOC since the middle of the nineties. CMOC can occur during or after adjuvant chemotherapy and the best management strategies to better define determinants of survival for patients are not well known. It appears that a better outcome of CMOC may be obtained by an aggressive treatment, if possible, including surgery, radiotherapy, and chemotherapy. Taking into account the increase in the incidence of the CMOC and their early occurrence, some authors have proposed a prophylactic brain radiotherapy in patients who receive adjuvant chemotherapy.

    Background Tumor cell fusion with motile bone marrow-derived cells (BMDCs) has long been posited as a mechanism for cancer metastasis. While there is much support for this from cell culture and animal studies, it has yet to be confirmed in human cancer, as tumor and marrow-derived cells from the same patient cannot be easily distinguished genetically. Methods We carried out genotyping of a metastatic melanoma to the brain that arose following allogeneic bone-marrow transplantation (BMT), using forensic short tandem repeat (STR) length-polymorphisms to distinguish donor and patient genomes. Tumor cells were isolated free of leucocytes by laser microdissection, and tumor and pre-transplant blood lymphocyte DNAs were analyzed for donor and patient alleles at 14 autosomal STR loci and the sex chromosomes. Results All alleles in the donor and patient pre-BMT lymphocytes were found in tumor cells. The alleles showed disproportionate relative abundances in similar patterns throughout the tumor, indicating the tumor was initiated by a clonal fusion event. Conclusions Our results strongly support fusion between a BMDC and a tumor cell playing a role in the origin of this metastasis. Depending on the frequency of such events, the findings could have important implications for understanding the generation of metastases, including the origins of tumor initiating cells and the cancer epigenome.

    Delineation of organs at risk (OARs) is a crucial step in surgical and treatment planning in brain cancer, where precise OARs volume delineation is required. However, this task is still often manually performed, which is time-consuming and prone to observer variability. To tackle these issues a deep learning approach based on stacking denoising auto-encoders has been proposed to segment the brainstem on magnetic resonance images in brain cancer context. Additionally to classical features used in machine learning to segment brain structures, two new features are suggested. Four experts participated in this study by segmenting the brainstem on 9 patients who underwent radiosurgery. Analysis of variance on shape and volume similarity metrics indicated that there were significant differences (p<0.05) between the groups of manual annotations and automatic segmentations. Experimental evaluation also showed an overlapping higher than 90% with respect to the ground truth. These results are comparable, and often higher, to those of the state of the art segmentation methods but with a considerably reduction of the segmentation time. PMID:27236370

    Administration of ineffective anticancer therapy is associated with unnecessary toxicity and development of resistant clones. Cancer stem-like cells (CSLCs) resist chemotherapy, thereby causing relapse of the disease. Thus, development of a test that identifies the most effective chemotherapy management offers great promise for individualized anticancer treatments. We have developed an ex vivo chemotherapy sensitivity assay (ChemoID), which measures the sensitivity of CSLCs as well as the bulk of tumor cells to a variety of chemotherapy agents. Two patients, a 21-year old male (patient 1) and a 5-month female (patient 2), affected by anaplastic WHO grade-III ependymoma were screened using the ChemoID assay. Patient 1 was found sensitive to the combination of irinotecan and bevacizumab, which resulted in a prolonged disease progression free period of 18 months. Following recurrence, the combination of various chemotherapy drugs was tested again with the ChemoID assay. We found that benzyl isothiocyanate (BITC) greatly increased the chemosensitivity of the ependymoma cells to the combination of irinotecan and bevacizumab. After patient 1 was treated for two months with irinotecan, bevacizumab and supplements of cruciferous vegetable extracts containing BITC, we observed over 50% tumoral regression in comparison with pre-ChemoID scan as evidenced by MRI. Patient 2 was found resistant to all treatments tested and following 6 cycles of vincristine, carboplatin, cyclophosphamide, etoposide, and cisplatin in various combinations, the tumor of this patient rapidly progressed and proton beam therapy was recommended. As expected animal studies conducted with patient derived xenografts treated with ChemoID screened drugs recapitulated the clinical observation. This assay demonstrates that patients with the same histological stage and grade of cancer may vary considerably in their clinical response, suggesting that ChemoID testing which measures the sensitivity of CSLCs as

    Background Brain tumor patients are quite different from other populations of cancer patients due to the complexity of supportive care needs, the trajectory of disease, the very short life expectancy, and resulting need for a specific palliative approach. Methods A pilot program of comprehensive palliative care for brain tumor patients was started in the Regina Elena National Cancer Institute of Rome in October 2000, supported by the Lazio Regional Health System. The aim of this model of assistance was to meet patient's needs for care in all stages of disease, support the families, and reduce the rehospitalization rate. The efficacy of the model of care was evaluated analyzing the place of death, caregiver satisfaction, rehospitalization rate, and the impact on costs to the health system. Results From October 2000 to December 2012, 848 patients affected by brain tumor were enrolled in a comprehensive program of neuro-oncological home care. Out of 529 patients who died, 323 (61%) were assisted at home until death, 117 (22.2%) died in hospital, and 89 (16.8%) died in hospice. A cost-effectiveness analysis demonstrated a significant reduction in hospital readmission rates in the last 2 months of life compared with the control group (16.7% vs 38%; P < .001). Conclusions Our findings concerning death at home, rehospitalization rate, quality of life, and satisfaction of patients and their relatives with the care received suggest that a neuro-oncologic palliative home-care program has a positive impact on the quality of care for brain tumor patients, particularly at the end of life.

    Background Health related quality of life (HRQOL) has increasingly emphasized on cancer patients. The psychometric properties of the standard Chinese version of the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 (EORTC QLQ-C30, version 3.0) in brain tumor patients wasn't proven, and there was no baseline HRQOL in brain tumor patients prior to surgery. Methods The questionnaire EORTC QLQ-C30 (version 3.0) was administered at three time points: T1, the first or the second day that patients were hospitalized after the brain tumor suspected or diagnosed by MRI or CT; T2, 1 to 2 days after T1, (T1 and T2 were both before surgery); T3, the day before discharge. Clinical variables included disease histologic types, cognitive function, and Karnofsky Performance Status. Results Cronbach's alpha coefficients for multi-item scales were greater than .70 and multitrait scaling analysis showed that most of the item-scale correlation coefficients met the standards of convergent and discriminant validity, except for the cognitive functioning scale. All scales and items exhibited construct validity. Score changes over peri-operation were observed in physical and role functioning scales. Compared with mixed cancer patients assessed after surgery but before adjuvant treatment, brain tumor patients assessed pre-surgery presented better function and fewer symptoms. Conclusions The standard Chinese version of the EORTC QLQ-C30 was overall a valid instrument to assess HRQOL in brain tumor patients in China. The baseline HRQOL in brain tumor patients pre-surgery was better than that in mixed cancer patients post-surgery. Future study should modify cognitive functioning scale and examine test-retest reliability and response validity. PMID:21513533

    Purpose/Objectives: The aim of this study was to evaluate the impact of definitive thoracic chemoradiation therapy following surgery or stereotactic radiosurgery (SRS) and whole-brain radiation therapy (WBRT) on the outcomes of patients with non-small cell lung cancer (NSCLC) with synchronous solitary brain metastasis (SSBM). Methods and Materials: A total of 63 NSCLC patients with SSBM were retrospectively evaluated. Patients were staged using positron emission tomography-computed tomography in addition to conventional staging tools. Thoracic radiation therapy (TRT) with a total dose of 66 Gy in 2 Gy fractions was delivered along with 2 cycles of cisplatin-based chemotherapy following either surgery plus 30 Gy of WBRT (n=33) or SRS plus 30 Gy of WBRT (n=30) for BM. Results: Overall, the treatment was well tolerated. All patients received planned TRT, and 57 patients (90.5%) were also able to receive 2 cycles of chemotherapy. At a median follow-up of 25.3 months (7.1-52.1 months), the median months of overall, locoregional progression-free, neurological progression-free, and progression-free survival were 28.6, 17.7, 26.4, and 14.6, respectively. Both univariate and multivariate analyses revealed that patients with a T1-T2 thoracic disease burden (P=.001), a nodal stage of N0-N1 (P=.003), and no weight loss (P=.008) exhibited superior survival. Conclusions: In the present series, surgical and radiosurgical treatments directed toward SSBM in NSCLC patients were equally effective. The similarities between the present survival outcomes and those reported in other studies for locally advanced NSCLC patients indicate the potentially curative role of definitive chemoradiation therapy for highly selected patients with SSBM.

    Small-cell lung cancer is a highly aggressive carcinoma, with poorer prognosis in patients with brain metastases. We present the case of a 49-year-old woman diagnosed with a cerebellar tumour which, following surgery, was revealed to be a metastatic small-cell lung carcinoma. Subsequent CT and PET scanning showed a small, isolated 8 mm nodule in the upper lobe of the right lung. The patient was suffering from schizophrenia and has been treated with clozapine for 17 years. Because of the unusual presentation, there was no therapy given for the primary tumour at the time, and systemic therapy or surgery was discussed. However, 18 months later, the nodule was slightly larger (14 mm), and surgery was performed. On pathology examination, the tumour was presented as a typical small-cell carcinoma. Standard chest irradiation with systemic chemotherapy was given. At the time of writing, 39 months after diagnosis of metastatic small-cell carcinoma, the patient is disease free. However, this case is unusual in that a long-term observation of a small stable primary tumour in the lung took place without any therapy being given. This case strongly supports the thesis that small-cell lung cancer may comprise a heterogeneous group of tumours with different biological properties. The proapoptotic effect of clozapine may be also taken into account. PMID:20537425

    Background Brain metastases from esophageal carcinoma have historically been rare and associated with poor prognosis. With improvements in systemic disease control, the incidence of brain metastases is expected to rise. To better inform management decisions, we sought to identify factors associated with survival in patients with brain metastasis from esophageal cancer. Methods We retrospectively identified 49 patients with brain metastasis from stage I–IV primary esophageal cancer treated with surgery, radiation, or a combination of modalities at our tertiary referral center between 1998 and 2015. Medical records were reviewed to collect demographic and clinical information. Results Median age at diagnosis of the primary esophageal cancer was 60 years. Forty-one (84%) patients were male and forty patients (82%) had adenocarcinoma. Median overall survival (MS) following esophageal cancer diagnosis was 24 months (range, 3–71 months), and median survival after the identification of brain metastases was 5 months (range, 1–52 months). On univariate analysis, only patients with poor Karnofsky performance status (KPS <70), recursive partitioning analysis (RPA) classification (III), or 3 or more brain metastases were found to have worsened survival after the diagnosis of brain metastases (all P<0.01). Factors not associated with survival were age, gender, histology (adenocarcinoma vs. other), palliative-intent treatment of the primary tumor, time to diagnosis of brain metastases from initial diagnosis, uncontrolled primary tumor at time of brain metastasis diagnosis, or extracranial metastases. On multivariate analysis (MVA, KPS excluded), patients with RPA class I (MS, 14.6 months) or II (MS, 5.0 months) disease had significantly improved overall survival compared to class III disease (MS, 1.6 months, P<0.01). Also on MVA, patients with 1 (MS, 10.7 months) or 2 (MS, 4.7 months) brain metastases had significantly improved overall survival compared to patients with 3

    The purpose of this study was to compare the radiation-induced second cancer risks for in-field and out-of-field organs and tissues for pencil beam scanning (PBS) and passive scattering proton therapy (PPT) and assess the impact of adding patient-specific apertures to sharpen the penumbra in pencil beam scanning for pediatric brain tumor patients. Five proton therapy plans were created for each of three pediatric patients using PPT as well as PBS with two spot sizes (average sigma of ~17 mm and ~8 mm at isocenter) and choice of patient-specific apertures. The lifetime attributable second malignancy risks for both in-field and out-of-field tissues and organs were compared among five delivery techniques. The risk for in-field tissues was calculated using the organ equivalent dose, which is determined by the dose volume histogram. For out-of-field organs, the organ-specific dose equivalent from secondary neutrons was calculated using Monte Carlo and anthropomorphic pediatric phantoms. We find that either for small spot size PBS or for large spot size PBS, a patient-specific aperture reduces the in-field cancer risk to values lower than that for PPT. The reduction for large spot sizes (on average 43%) is larger than for small spot sizes (on average 21%). For out-of-field organs, the risk varies only marginally by employing a patient-specific aperture (on average from  -2% to 16% with increasing distance from the tumor), but is still one to two orders of magnitude lower than that for PPT. In conclusion, when pencil beam spot sizes are large, the addition of apertures to sharpen the penumbra decreases the in-field radiation-induced secondary cancer risk. There is a slight increase in out-of-field cancer risk as a result of neutron scatter from the aperture, but this risk is by far outweighed by the in-field risk benefit from using an aperture with a large PBS spot size. In general, the risk for developing a second malignancy in out-of-field organs for PBS remains

We find that either for small spot size PBS or for large spot size PBS, a patient-specific aperture reduces the in-field cancer risk to values lower than that for PPT. The reduction for large spot sizes (on average 43%) is larger than for small spot sizes (on average 21%). For out-of-field organs, the risk varies only marginally by employing a patient-specific aperture (on average from  -2% to 16% with increasing distance from the tumor), but is still one to two orders of magnitude lower than that for PPT. In conclusion, when pencil beam spot sizes are large, the addition of apertures to sharpen the penumbra decreases the in-field radiation-induced secondary cancer risk. There is a slight increase in out-of-field cancer risk as a result of neutron scatter from the aperture, but this risk is by far outweighed by the in-field risk benefit from using an aperture with a large PBS spot size. In general, the risk for developing a second malignancy in out-of-field organs for PBS remains

    Metastasis is the relenteless pursuit of cancer to escape its primary site and colonize distant organs. This malignant evolutionary process is biologically heterogeneous, yet one unifying element is the critical role of the microenvironment for arriving metastatic cells. Historically brain metastases were rarely investigated since patients with advanced cancer were considered terminal. Fortunately, advances in molecular therapies have led to patients living longer with metastatic cancer. However, one site remains recalcitrant to our treatment efforts – the brain. The central nervous system is the most complex biological system, which poses unique obstacles but also harbors opportunities for discovery. Much of what we know about the brain microenvironment comes from neuroscience. We suggest that the interrelated cellular responses in traumatic brain injury may guide us towards new perspectives in understanding brain metastases. In this view, brain metastases may be conceptualized as progressive oncologic injury to the nervous system. This review discusses our evolving understanding of the bidirectional interactions between the brain milieu and metastatic cancer. PMID:25035392

    Although cranial radiotherapy is considered the standard treatment for brain metastasis (BM), EGFR tyrosine kinase inhibitors (TKIs) have shown promising activity in EGFR mutant non-small cell lung cancer (NSCLC) patients with BM. However, the efficacy of sequential cranial radiotherapy in patients with EGFR mutant NSCLC who are treated with EGFR TKIs remains to be determined. Patients with NSCLC who harbored an EGFR mutation and whose BM had been treated with EGFR TKIs were retrospectively reviewed. The clinical outcomes of patients treated with EGFR TKIs alone and those treated with cranial radiotherapy followed by EGFR TKIs (additive therapy) were compared. Of the 573 patients with NSCLC with BM who harbored an EGFR mutation and had received EGFR TKIs, 121 (21.1 %) had BM at the time of initial diagnosis. Fifty-nine (49 %) patients were treated with additive therapy, whereas 62 (51 %) patients were treated only with EGFR TKIs. No significant differences were observed between the additive therapy group and the EGFR TKI alone group regarding intracranial progression-free survival (PFS) (16.6 vs 21.0 months, p = 0.492) or extracranial PFS (12.9 vs 15.0 months, p = 0.770). The 3-year survival rates were similar in both groups (71.9 vs 68.2 %, p = 0.675). Additive therapy consisting of cranial radiotherapy followed by EGFR TKI treatment did not improve OS or intracranial PFS compared with EGFR TKI treatment alone in EGFR mutant NSCLC patients with BM. Further prospective studies are needed to determine the precise benefits of sequential cranial radiotherapy in EGFR mutant NSCLC treated with EGFR TKIs. PMID:27447711

    Brain cancer tumors cause disruption of the selective properties of vascular endothelia, even causing disruptions in the very selective blood–brain barrier, which are collectively referred to as the blood–brain–tumor barrier. Nanoparticles (NPs) have previously shown great promise in taking advantage of this increased vascular permeability in other cancers, which results in increased accumulation in these cancers over time due to the accompanying loss of an effective lymph system. NPs have therefore attracted increased attention for treating brain cancer. While this research is just beginning, there have been many successes demonstrated thus far in both the laboratory and clinical setting. This review serves to present the reader with an overview of NPs for treating brain cancer and to provide an outlook on what may come in the future. For NPs, just like the blood–brain–tumor barrier, the future is wide open. PMID:23256496

    Background Brain-derived neurotrophic factor (BDNF), a neurotrophin that regulates neuronal function and development, is implicated in several neurodegenerative conditions. Preliminary data suggest that a reduction of BDNF concentrations may lead to postchemotherapy cognitive impairment. We hypothesized that a single nucleotide polymorphism (rs6265) of the BDNF gene may predispose patients to cognitive impairment. This study aimed to evaluate the effect of BDNF gene polymorphism on chemotherapy-associated cognitive impairment. Methods Overall, 145 patients receiving chemotherapy for early-stage breast cancer (mean age: 50.8 ± 8.8 y; 82.1% Chinese) were recruited. Patients' cognitive functions were assessed longitudinally using the validated Functional Assessment of Cancer Therapy–Cognitive Function (v.3) and an objective computerized tool, Headminder. Genotyping was performed using Sanger sequencing. Logistic regression was used to evaluate the association between BDNF Val66Met polymorphism and cognition after adjusting for ethnicity and clinically important covariates. Results Of the 145 patients, 54 (37%) reported cognitive impairment postchemotherapy. The Met/Met genotype was associated with statistically significant lower odds of developing cognitive impairment (odds ratio [OR] = 0.26; 95% CI: 0.08–0.92; P = .036). The Met carriers were less likely to experience impairment in the domains of verbal fluency (OR = 0.34; 95% CI: 0.12–0.90; P = .031) and multitasking ability (OR = 0.37; 95% CI: 0.15–0.91; P = .030) compared with the Val/Val homozygote. No associations were observed between Headminder and the BDNF Val66Met polymorphism. Conclusions This is the first study to provide evidence that carriers of the BDNF Met allele are protected against chemotherapy-associated cognitive impairment. Further studies are required to validate the findings. PMID:26289590

    An increase in the incidence of breast cancer patients with brain metastases has been observed over the last years, mainly because the recent development of new drugs including therapies targeting HER2 (human epidermal growth factor receptor 2) resulted in an increased survival of these patients. With HER2+ patients living longer and the well-known neurotropism of HER2+ tumour cells, the resulting high incidence of brain metastases is not really surprising. Moreover, brain metastases more often occur within a context of existing extracranial metastases. These need to be treated at the same time in order to favourably impact patients' survival. Consequently, the management of breast cancer patients with brain metastases clearly relies on a multidisciplinary approach, including systemic treatment. A working group including neuro-oncologists, neurosurgeons, radiation oncologists and oncologists was created in order to provide French national guidelines for the management of brain metastases within the "Association des neuro-oncologues d'expression française" (ANOCEF). The recommendations regarding the systemic treatment in breast cancer patients are reported here including key features of their management. PMID:25662600

    Brain metastases are frequently encountered in patients with non-small cell lung cancer (NSCLC) and are a significant cause of morbidity and mortality. Antiangiogenesis therapy plays a major role in the management of brain metastases in lung cancer. Bevacizumab have become the novel method for the treatment of lung cancer with brain metastases beyond the whole brain radiation therapy, stereotactic radiosurgery and chemotherapy. Recently, more and more studies and trials laid emphasis on the bevacizumab for NSCLC with brain metastases treatment. The key point is the efficacy and safety. In this review, bevacizumab therapy of NSCLC with brain metastases were summarized. PMID:27561800

    Introduction: Adrenocortical carcinoma (ACC) is a heterogeneous and rare disease. At presentation or at the time of a recurrence, the disease commonly spreads to the liver, lungs, lymph nodes, and bones. The brain has only rarely been reported as a site of metastases. Objective: The aims of this report were to describe the clinical characteristics of patients with ACC who developed brain metastasis and were evaluated at the National Cancer Institute. Methods: We describe the history and clinical presentation of six patients with ACC and metastatic disease in the brain. Images of the six patients and pathology slides were reviewed when available. Results: The median age at the time of the diagnosis of ACC was 42 years. The median time from the initial diagnosis until the presentation of brain metastasis was 43 months. As a group the patients had previously received multiples lines of chemotherapy (median of three), and they presented with one to three metastatic brain lesions. Four patients underwent metastasectomy, one had radiosurgery, and one had both modalities. Two patients are still alive, three died, between 2 and 14 months after the diagnosis of brain metastases, and one was lost to follow-up. Conclusion: Patients with advanced ACC can rarely present with metastasis to the brain, most often long after the initial diagnosis. Timely diagnosis of brain metastasis with appropriate intervention after discussion in a multidisciplinary meeting can improve the prognosis in this particular scenario. PMID:25412413

    More complete brain cancer resection can prolong survival and delay recurrence. However, it is challenging to distinguish cancer from non-cancer tissues intraoperatively, especially at the transitional, infiltrative zones. This is especially critical in eloquent regions (e.g. speech and motor areas). This study tested the feasibility of label-free, quantitative optical coherence tomography (OCT) for differentiating cancer from non-cancer in human brain tissues. Fresh ex vivo human brain tissues were obtained from 32 patients with grades II-IV brain cancer and 5 patients with non-cancer brain pathologies. Based on volumetric OCT imaging data, pathologically confirmed brain cancer tissues (both high-grade and low-grade) had significantly lower optical attenuation values at both cancer core and infiltrated zones when compared with non-cancer white matter, and OCT achieved high sensitivity and specificity at an attenuation threshold of 5.5 mm-1 for brain cancer patients. We also used this attenuation threshold to confirm the intraoperative feasibility of performing in vivo OCT-guided surgery using a murine model harboring human brain cancer. Our OCT system was capable of processing and displaying a color-coded optical property map in real time at a rate of 110-215 frames per second, or 1.2-2.4 seconds for an 8-16 mm3 tissue volume, thus providing direct visual cues for cancer versus non-cancer areas. Our study demonstrates the translational and practical potential of OCT in differentiating cancer from non-cancer tissue. Its intraoperative use may facilitate safe and extensive resection of infiltrative brain cancers and consequently lead to improved outcomes when compared with current clinical standards.

    Breast cancer brain metastases (BCBMs) are the second most frequent secondary central nervous system metastases following those associated with non-small-cell lung cancer. It is increasingly evident that BCBM arises as a function of the biology of the primary tumor and the metastatic niche, which combine to create a unique microenvironment in the brain impacting both metastatic colonization and therapeutic response. Clinical outcomes are improving for BCBM patients as a result of modern combinatorial therapies, challenging the traditionally nihilistic approach to this patient subgroup. This review will focus on the breast cancer subtypes with the highest incidence of BCBM-human epidermal growth factor receptor 2 (HER2)-positive breast cancer, and triple-negative (estrogen receptor [ER]-negative, progesterone receptor [PR]-negative, and HER2-negative) breast cancer (TNBC)-and will characterize differences in the clinical behavior of brain metastases that arise from these different subtypes. We will also highlight some of the recent preclinical studies that may shed light on the biological mechanisms and mediators underlying brain metastases. Finally, we will review published and current prospective trials of systemic therapies specifically for BCBM, including novel pathway-specific therapies. PMID:22888567

    Brain metastases are frequent in patients with advanced breast cancer and are associated with poor prognosis. However, unique molecular biomarkers have not yet been established. We hypothesized that microRNA-20b (miR-20b) plays a role in breast cancer brain metastasis. Our study cohort comprised of eleven breast cancer patients with brain metastasis and nine control patients (age, stage, and follow-up matched) with breast cancer without brain metastasis. Cases were reviewed microscopically to select tumor blocks with >50% tumor cells, RNA was extracted from formalin-fixed paraffin-embedded (FFPE) tumor tissue blocks and expression of miR-20b analyzed using qRT-PCR. We further tested the effect of miR-20b overexpression on colony formation and invasion in vitro using MCF-7 and MDA-MB-231 cells. In the patient-derived samples, miR-20b expression was significantly higher in brain metastases of breast cancer patients, compared to primary breast tumors as well as the patients without brain metastasis. miR-20b also significantly induced the colony formation and invasiveness of breast cancer cells. Further, miR-20b levels were observed to be high in brain-metastasizing cells, compared to bone-metastasizing cells. Together, our findings suggest a novel role of miR-20b in breast cancer brain metastasis that warrants further investigation for its potential to be developed as prognostic and/or therapeutic target.

    About 10% of all cancer patients will develop brain metastases during advanced disease progression. Interestingly, the vast majority of brain metastases occur in only three types of cancer: Melanoma, lung and breast cancer. In this review, we focus on summarizing the prognosis and impact of surgical resection of brain metastases originating from gastrointestinal cancers such as esophageal, gastric, pancreatic and colorectal cancer. The incidence of brain metastases is <1% in pancreatic and gastric cancer and <4% in esophageal and colorectal cancer. Overall, prognosis of these patients is very poor with a median survival in the range of only months. Interestingly, a substantial number of patients who had received surgical resection of brain metastases showed prolonged survival. However, it should be taken into account that all these studies were not randomized and it is likely that patients selected for surgical treatment presented with other important prognostic factors such as solitary brain metastases and exclusion of extra-cranial disease. Nevertheless, other reports have demonstrated long-term survival of patients upon resection of brain metastases originating from gastrointestinal cancers. Thus, it appears to be justified to consider aggressive surgical approaches for these patients. PMID:25247579

    Physiotherapy of cancer patients is one of the most controversial issues in our country. Malignant diseases are firstly mentioned as a contraindication of physiotherapy. Until now, physiotherapy was not suggested (or only in limited accessibility) for those patients who had malignant disease in medical history. International medical practice was less restrictive in managing this topic. The development of imaging techniques put this question in a new light. On the basis of evidence, the majority of articles have reported beneficial effects of physiotherapy in cancer patients, and only few articles mentioned it as harmful. Of course, each patient requires an individual assessment, however, if we exclude the possibility of tumor recurrence and metastasis, most of physiotherapy procedures can be used safely. One of the aims of this review is to support the physicians' decisions when to prescribe treatments, in such a way, that more patients could receive physiotherapy. Orv.

    Insomnia affects up to 50% of patients with cancer, but has received little attention from the oncology community compared with other symptoms such as pain and fatigue. Insomnia and subsequent sleep disturbances can lead to fatigue, mood disturbances, and contribute to immunosuppression, which can have a profound impact on quality of life and perhaps affect the course of disease. Insomnia in cancer patients must be distinguished from cancer-related fatigue. Although they are 2 distinct conditions, insomnia and fatigue are interrelated. Insomnia often leads to daytime fatigue that interferes with normal functioning. Conversely, daytime fatigue can lead to behaviors such as napping, which result in insomnia. The primary goal of insomnia treatment should first be to relieve any underlying disorder (eg, cancer pain, depression, anxiety) that may be causing the sleep disturbance. Because insomnia in this patient population may be due to a variety of causes, treatment must be multimodal and include both pharmacologic and nonpharmacologic therapies. A plan that combines attention to sleep hygiene and cognitive-behavioral therapy with prescription of hypnotic medications can help relieve the symptoms of insomnia in cancer patients and improve their quality of life.

    Purpose: To prospectively compare the effect of prophylactic and therapeutic whole brain radiotherapy (WBRT) on memory function in patients with and without brain metastases. Methods and Materials: Adult patients with and without brain metastases (n = 44) were prospectively evaluated with serial cognitive testing, before RT (T0), after starting RT (T1), at the end of RT (T2), and 6-8 weeks (T3) after RT completion. Data were obtained from small-cell lung cancer patients treated with prophylactic cranial irradiation, patients with brain metastases treated with therapeutic cranial irradiation (TCI), and breast cancer patients treated with RT to the breast. Results: Before therapy, prophylactic cranial irradiation patients performed worse than TCI patients or than controls on most test scores. During and after WBRT, verbal memory function was influenced by pretreatment cognitive status (p < 0.001) and to a lesser extent by WBRT. Acute (T1) radiation effects on verbal memory function were only observed in TCI patients (p = 0.031). Subacute (T3) radiation effects on verbal memory function were observed in both TCI and prophylactic cranial irradiation patients (p = 0.006). These effects were more pronounced in patients with above-average performance at baseline. Visual memory and attention were not influenced by WBRT. Conclusions: The results of our study have shown that WBRT causes cognitive dysfunction immediately after the beginning of RT in patients with brain metastases only. At 6-8 weeks after the end of WBRT, cognitive dysfunction was seen in patients with and without brain metastases. Because cognitive dysfunction after WBRT is restricted to verbal memory, patients should not avoid WBRT because of a fear of neurocognitive side effects.

    The brain is a common site of metastatic disease in patients with breast cancer, which has few therapeutic options and dismal outcomes. The purpose of our study was to identify common and rare events that underlie breast cancer brain metastasis. We performed deep genomic profiling, which integrated gene copy number, gene expression and DNA methylation datasets on a collection of breast brain metastases. We identified frequent large chromosomal gains in 1q, 5p, 8q, 11q, and 20q and frequent broad-level deletions involving 8p, 17p, 21p and Xq. Frequently amplified and overexpressed genes included ATAD2, BRAF, DERL1, DNMTRB and NEK2A. The ATM, CRYAB and HSPB2 genes were commonly deleted and underexpressed. Knowledge mining revealed enrichment in cell cycle and G2/M transition pathways, which contained AURKA, AURKB and FOXM1. Using the PAM50 breast cancer intrinsic classifier, Luminal B, Her2+/ER negative, and basal-like tumors were identified as the most commonly represented breast cancer subtypes in our brain metastasis cohort. While overall methylation levels were increased in breast cancer brain metastasis, basal-like brain metastases were associated with significantly lower levels of methylation. Integrating DNA methylation data with gene expression revealed defects in cell migration and adhesion due to hypermethylation and downregulation of PENK, EDN3, and ITGAM. Hypomethylation and upregulation of KRT8 likely affects adhesion and permeability. Genomic and epigenomic profiling of breast brain metastasis has provided insight into the somatic events underlying this disease, which have potential in forming the basis of future therapeutic strategies.

    This comprehensive review provides information on epidemiology, size, grade, cerebral localization, clinical symptoms, treatments, and factors associated with longer survival in 14,599 patients with brain metastasis from breast cancer; the molecular features of breast cancers most likely to develop brain metastases and the potential use of these predictive molecular alterations for patient management and future therapeutic targets are also addressed. The review covers the data from 106 articles representing this subject in the era of modern neuroimaging (past 35 years). The incidence of brain metastasis from breast cancer (24 % in this review) is increasing due to advances in both imaging technologies leading to earlier detection of the brain metastases and introduction of novel therapies resulting in longer survival from the primary breast cancer. The mean age at the time of breast cancer and brain metastasis diagnoses was 50.3 and 48.8 years respectively. Axillary node metastasis was noted in 32.8 % of the patients who developed brain metastasis. The median time intervals between the diagnosis of breast cancer to identification of brain metastasis and from identification of brain metastasis to death were 34 and 15 months, respectively. The most common symptoms experienced in patients with brain metastasis consisted of headache (35 %), vomiting (26 %), nausea (23 %), hemiparesis (22 %), visual changes (13 %) and seizures (12 %). A majority of the patients had multiple metastases (54.2 %). Cerebellum and frontal lobes were the most common sites of metastasis (33 and 16 %, respectively). Of the primary tumors for which biomarkers were recorded, 37 % were estrogen receptor (ER)+, 41 % ER-, 36 % progesterone receptor (PR)+, 34 % PR-, 35 % human epithelial growth factor receptor 2 (HER2)+, 41 % HER2-, 27 % triple negative and 18 % triple positive (TP).

    Breast cancer occurs in approximately 1 in 8 women and 1 in 37 women with breast cancer succumbed to the disease. Over the past decades, new diagnostic tools and treatments have substantially improved the prognosis of women with local diseases. However, women with metastatic disease still have a dismal prognosis without effective treatments. Among different molecular subtypes of breast cancer, the HER2-enriched and basal-like subtypes typically have higher rates of metastasis to the brain. Basal-like metastatic breast tumors frequently express EGFR. Consequently, HER2- and EGFR-targeted therapies are being used in the clinic and/or evaluated in clinical trials for treating breast cancer patients with brain metastases. In this review, we will first provide an overview of the HER2 and EGFR signaling pathways. The roles that EGFR and HER2 play in breast cancer metastasis to the brain will then be discussed. Finally, we will summarize the preclinical and clinical effects of EGFR- and HER2-targeted therapies on breast cancer metastasis. PMID:26709660

    Lung cancer represents the leading cause of cancer-related mortality throughout the world. Patients die of local progression, disseminated disease, or both. At least one third of the people with lung cancer develop brain metastases at some point during their disease, even often before the diagnosis of lung cancer is made. The high rate of brain metastasis makes lung cancer the most common type of tumor to spread to the brain. It is critical to understand the biologic basis of brain metastases to develop novel diagnostic and therapeutic approaches. This review will focus on the emerging data supporting the involvement of the chemokine CXCL12 and its receptor CXCR4 in the brain metastatic evolution of non-small-cell lung cancer (NSCLC) and the pharmacological tools that may be used to interfere with this signaling axis.

    Prevalence of brain metastases is increasing in breast cancer. Brain metastases represent a poor-prognosis disease for which local treatments continue to play a major role. In spite of the presence of a physiological blood-brain barrier limiting their activity, some systemic treatments may display a significant antitumor activity at the central nervous system level. In HER2-positive metastatic breast cancer with brain metastases not previously treated with whole brain radiotherapy, capecitabine and lapatinib combination obtains a volumetric reponse in two thirds of patients (LANDSCAPE study). If confirmed, these results could modify in selected patients the layout of therapeutic strategies. Promoting novel targeted approaches and innovative therapeutic combinations is a critical need to improve survival of breast cancer patients with brain metastases. PMID:23305997

    Present literature states that people with acquired organic brain dysfunctions face problems with attention, executive functions and social interaction. During the past years an increasing number of patients with organic brain disorders have been committed into our forensic psychiatry. In current literature studies on this group of patients are underrepresented. This study wanted to verify the impairment of cognitive functions of this specific group of patients. Included were all patients of the forensic psychiatry in Rostock (Mecklenburg-Western-Pomerania) with a primary or secondary organic brain dysfunction who have been committed into the clinic since 2009. These patients went through an extensive neuropsychological test battery. It was found that patients affected by organic brain dysfunction achieve lower results in the neuropsychological testing than non impaired patients, but their results are not as below average than it would have been expected. Further studies should show, if these patients are able to improve their performance while successfully undergoing psychotherapy. PMID:21905991

    Breast cancers that overexpress the human epidermal growth factor receptor 2 (HER-2) have a predilection to metastasize to the brain. Therapeutic options for brain metastases with systemic therapy remain a challenge in those patients since targeted and chemotherapeutic agents have limited penetration through the blood-brain barrier. Here we report the case of a patient with brain metastases from breast cancer overexpressing HER-2 who achieved a complete radiologic response after treatment by radiation and concurrent Lapatinib and Capecitabine.

    Abstract The aim of this study was to investigate whether statin utilization is associated with brain cancer risk. A population-based case–control study was conducted using nationally representative claims data from the National Health Insurance Bureau in Taiwan. Cases included all patients 50 years and older who received an index diagnosis of brain cancer between 2004 and 2011. Our controls were matched by age, sex, and index date. We estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) using multiple logistic regression. We examined 213 brain cancer cases and 852 controls. The unadjusted ORs for any statin prescription was 0.77 (95% CI = 0.50–1.18) and the adjusted OR was 0.59 (95% CI = 0.37–0.96). Compared with no use of statins, the adjusted ORs were 0.68 (95% CI = 0.38–1.24) for the group having been prescribed with statins with cumulative defined daily dose (DDD) below 144.67 DDDs and 0.50 (95% CI = 0.28–0.97) for the group with the cumulative statin use of 144.67 DDDs or more. The results of this study suggest that statins may reduce the risk of brain cancer. PMID:27124024

    Although conventional chemotherapies are used to treat patients with malignancies, damage to normal cells is problematic. Blood-forming bone marrow cells are the most adversely affected. It is therefore necessary to find alternative agents that can kill cancer cells but have minimal effects on normal cells. We investigated the brain cancer cell-killing activity of a homeopathic medicine, Ruta, isolated from a plant, Ruta graveolens. We treated human brain cancer and HL-60 leukemia cells, normal B-lymphoid cells, and murine melanoma cells in vitro with different concentrations of Ruta in combination with Ca3(PO4)2. Fifteen patients diagnosed with intracranial tumors were treated with Ruta 6 and Ca3(PO4)2. Of these 15 patients, 6 of the 7 glioma patients showed complete regression of tumors. Normal human blood lymphocytes, B-lymphoid cells, and brain cancer cells treated with Ruta in vitro were examined for telomere dynamics, mitotic catastrophe, and apoptosis to understand the possible mechanism of cell-killing, using conventional and molecular cytogenetic techniques. Both in vivo and in vitro results showed induction of survival-signaling pathways in normal lymphocytes and induction of death-signaling pathways in brain cancer cells. Cancer cell death was initiated by telomere erosion and completed through mitotic catastrophe events. We propose that Ruta in combination with Ca3(PO4)2 could be used for effective treatment of brain cancers, particularly glioma. PMID:12963976

    Brain metastases occur in about 10–30% of breast cancer patients, which culminates in a poor prognosis. It is therefore critical to understand the molecular mechanisms underlying brain metastatic processes to identify relevant targets. We hypothesized that breast cancer cells must express brain-associated markers that would enable their invasion and survival in the brain microenvironment. We assessed a panel of brain-predominant markers and found an elevation of several neuronal markers (βIII tubulin, Nestin and AchE) in brain metastatic breast cancer cells. Among these neuronal predominant markers, in silico analysis revealed overexpression of βIII tubulin (TUBB3) in breast cancer brain metastases (BCBM) and its expression was significantly associated with distant metastases. TUBB3 knockdown studies were conducted in breast cancer models (MDA-Br, GLIM2 and MDA-MB-468) which revealed significant reduction in their invasive capabilities. MDA-Br cells with suppressed TUBB3 also demonstrated loss of key signaling molecules such as β3 integrin, pFAK, and pSrc in vitro. Furthermore, TUBB3 knockdown in a brain metastatic breast cancer cell line compromised its metastatic ability in vivo, and significantly improved survival in a brain metastasis model. These results implicate a critical role of TUBB3 in conferring brain metastatic potential to breast cancer cells. PMID:25724666

    We present a young woman with ROS1 gene rearranged non-small cell lung cancer (NSCLC) with brain metastases. ROS is a proto-oncogene tyrosine protein kinase. The patient received a partial course of whole brain radiation therapy and experienced a sustained partial response in the brain. We hypothesize that ROS1 rearranged NSCLC brain metastases may be particularly sensitive to radiation therapy. PMID:26159887

  10. Compromised quality of life in adult patients who have received a radiation dose towards the basal part of the brain. A case-control study in long-term survivors from cancer in the head and neck region

    2012-01-01

    Background Adult patients with hypothalamic-pituitary disorders have compromised quality of life (QoL). Whether this is due to their endocrine consequences (hypopituitarism), their underlying hypothalamic-pituitary disorder or both is still under debate. The aim of this trial was to measure quality of life (QoL) in long-term cancer survivors who have received a radiation dose to the basal part of the brain and the pituitary. Methods Consecutive patients (n=101) treated for oropharyngeal or epipharyngeal cancer with radiotherapy followed free of cancer for a period of 4 to10 years were identified. Fifteen patients (median age 56 years) with no concomitant illness and no hypopituitarism after careful endocrine evaluation were included in a case-control study with matched healthy controls. Doses to the hypothalamic-pituitary region were calculated. QoL was assessed using the Symptom check list (SCL)-90, Nottingham Health Profile (NHP), and Psychological Well Being (PGWB) questionnaires. Level of physical activity was assessed using the Baecke questionnaire. Results The median accumulated dose was 1.9 Gy (1.5–2.2 Gy) to the hypothalamus and 2.4 Gy (1.8–3.3 Gy) to the pituitary gland in patients with oropharyngeal cancer and 6.0–9.3 Gy and 33.5–46.1 Gy, respectively in patients with epipharyngeal cancer (n=2). The patients showed significantly more anxiety and depressiveness, and lower vitality, than their matched controls. Conclusion In a group of long time survivors of head and neck cancer who hade received a low radiation dose to the hypothalamic-pituitary region and who had no endocrine consequences of disease or its treatment QoL was compromised as compared with well matched healthy controls.

    More complete brain cancer resection can prolong survival and delay recurrence. However, it is challenging to distinguish cancer from noncancer tissues intraoperatively, especially at the transitional, infiltrative zones. This is especially critical in eloquent regions (for example, speech and motor areas). This study tested the feasibility of label-free, quantitative optical coherence tomography (OCT) for differentiating cancer from noncancer in human brain tissues. Fresh ex vivo human brain tissues were obtained from 32 patients with grade II to IV brain cancer and 5 patients with noncancer brain pathologies. On the basis of volumetric OCT imaging data, pathologically confirmed brain cancer tissues (both high- and low-grade) had significantly lower optical attenuation values at both cancer core and infiltrated zones when compared with noncancer white matter, and OCT achieved high sensitivity and specificity at an attenuation threshold of 5.5 mm(-1) for brain cancer patients. We also used this attenuation threshold to confirm the intraoperative feasibility of performing in vivo OCT-guided surgery using a murine model harboring human brain cancer. Our OCT system was capable of processing and displaying a color-coded optical property map in real time at a rate of 110 to 215 frames per second, or 1.2 to 2.4 s for an 8- to 16-mm(3) tissue volume, thus providing direct visual cues for cancer versus noncancer areas. Our study demonstrates the translational and practical potential of OCT in differentiating cancer from noncancer tissue. Its intraoperative use may facilitate safe and extensive resection of infiltrative brain cancers and consequently lead to improved outcomes when compared with current clinical standards.

    Small cell lung cancer is the most aggressive histologic subtype of lung cancer, with a strong predilection for metastasizing to brain early. However, the cellular and molecular basis is poorly known. Here, we provided evidence to reveal the role of annexin A1 in small cell lung cancer metastasis to brain. Firstly, the elevated annexin A1 serum levels in small cell lung cancer patients were associated with brain metastasis. The levels of annexin A1 were also upregulated in NCI-H446 cells, a small cell lung cancer cell line, upon migration into the mice brain. More interestingly, annexin A1 was secreted by NCI-H446 cells in a time-dependent manner when co-culturing with human brain microvascular endothelial cells, which was identified with the detections of annexin A1 in the co-cultured cellular supernatants by ELISA and western blot. Further results showed that blockage of annexin A1 in the co-cultured cellular supernatants using a neutralized antibody significantly inhibited NCI-H446 cells adhesion to brain endothelium and its transendothelial migration. Conversely, the addition of Ac2-26, an annexin A1 mimic peptide, enhanced these effects. Furthermore, knockdown of annexin A1 in NCI-H446 cells prevented its transendothelial migration in vitro and metastasis to mice brain in vivo. Our data showed that small cell lung cancer cell in brain microvasculature microenvironment could express much more annexin A1 and release it outside, which facilitated small cell lung cancer cell to gain malignant properties of entry into brain. These findings provided a potential target for the management of SCLC brain metastasis. PMID:26135980

    Introduction: Afatinib is an effective first-line treatment in patients with epidermal growth factor receptor (EGFR)-mutated non–small-cell lung cancer (NSCLC) and has shown activity in patients progressing on EGFR-tyrosine kinase inhibitors (TKIs). First-line afatinib is also effective in patients with central nervous system (CNS) metastasis. Here we report on outcomes of pretreated NSCLC patients with CNS metastasis who received afatinib within a compassionate use program. Methods: Patients with NSCLC progressing after at least one line of chemotherapy and one line of EGFR-TKI treatment received afatinib. Medical history, patient demographics, EGFR mutational status, and adverse events including tumor progression were documented. Results: From 2010 to 2013, 573 patients were enrolled and 541 treated with afatinib. One hundred patients (66% female; median age, 60 years) had brain metastases and/or leptomeningeal disease with 74% having documented EGFR mutation. Median time to treatment failure for patients with CNS metastasis was 3.6 months, and did not differ from a matched group of 100 patients without CNS metastasis. Thirty-five percent (11 of 31) of evaluable patients had a cerebral response, five (16%) responded exclusively in brain. Response duration (range) was 120 (21–395) days. Sixty-six percent (21 of 32) of patients had cerebral disease control on afatinib. Data from one patient with an impressive response showed an afatinib concentration in the cerebrospinal fluid of nearly 1 nMol. Conclusion: Afatinib appears to penetrate into the CNS with concentrations high enough to have clinical effect on CNS metastases. Afatinib may therefore be an effective treatment for heavily pretreated patients with EGFR-mutated or EGFR–TKI-sensitive NSCLC and CNS metastasis. PMID:25247337

    Background Antacid treatments decrease the serum concentrations of first-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs), although it is unknown whether antacids affect clinical outcomes. As cerebrospinal fluid concentrations of TKIs are much lower than serum concentrations, we hypothesized that this drug-drug interaction might affect the prognosis of patients with de novo brain metastases. Materials and Methods This retrospective study evaluated 269 patients with EGFR-mutant non-small cell lung cancer (NSCLC) who had been diagnosed between December 2010 and December 2013, and had been treated using first-line first-generation EGFR-TKIs. Among these patients, we identified patients who concurrently used H2 receptor antagonists (H2RAs) and proton pump inhibitors (PPIs) as antacids. Patients who exhibited >30% overlap between the use of TKIs and antacids were considered antacid users. Results Fifty-seven patients (57/269, 21.2%) were antacid users, and antacid use did not significantly affect progression-free survival (PFS; no antacids: 11.2 months, H2RAs: 9.4 months, PPIs: 6.7 months; p = 0.234). However, antacid use significantly reduced overall survival (OS; no antacids: 25.0 months, H2RAs: 15.5 months, PPIs: 11.3 months; p = 0.002). Antacid use did not affect PFS for various metastasis sites, although antacid users with de novo brain metastases exhibited significantly shorter OS, compared to non-users (11.8 vs. 16.3 months, respectively; p = 0.041). Antacid use did not significantly affect OS in patients with bone, liver, or pleural metastases. Conclusion Antacid use reduced OS among patients with EGFR-mutant NSCLC who were treated using first-line first-generation EGFR-TKIs, and especially among patients with de novo brain metastases.

    The biology of breast cancer brain metastasis (BCBM) is poorly understood. We aimed to explore genes that are implicated in the process of brain metastasis of primary breast cancer (BC). NanoString nCounter Analysis covering 252 target genes was used for comparison of gene expression levels between 20 primary BCs that relapsed to brain and 41 BCBM samples. PAM50-based intrinsic subtypes such as HER2-enriched and basal-like were clearly over-represented in BCBM. A panel of 22 genes was found to be significantly differentially expressed between primary BC and BCBM. Five of these genes, CXCL12, MMP2, MMP11, VCAM1, and MME, which have previously been associated with tumor progression, angiogenesis, and metastasis, clearly discriminated between primary BC and BCBM. Notably, the five genes were significantly upregulated in primary BC compared to BCBM. Conversely, SOX2 and OLIG2 genes were upregulated in BCBM. These genes may participate in metastatic colonization but not in primary tumor development. Among patient-matched paired samples (n = 17), a PAM50 molecular subtype conversion was observed in eight cases (47.1%), with a trend toward unfavorable subtypes in patients with the distinct gene expression. Our findings, although not conclusive, reveal differentially expressed genes that might mediate the brain metastasis process. PMID:27340107

    The Unfolded Protein Response (UPR) is an adaptive cellular program used by eukaryotic cells to cope with protein misfolding stress in the Endoplasmic Reticulum (ER). During tumor development, cancer cells are facing intrinsic (oncogene activation) and extrinsic (limiting nutrient or oxygen supply; exposure to chemotherapies) challenges, with which they must cope to survive. Primary brain tumors are relatively rare but deadly and present a significant challenge in the determination of risk factors in the population. These tumors are inherently difficult to cure because of their protected location in the brain. As such surgery, radiation and chemotherapy options carry potentially lasting patient morbidity and incomplete tumor cure. Some of these tumors, such as glioblastoma, were reported to present features of ER stress and to depend on UPR activation to sustain growth, but to date there is no clear general representation of the ER stress status in primary brain tumors. In this review, we describe the key molecular mechanisms controlling the UPR and their implication in cancers. Then we extensively review the literature reporting the status of ER stress in various primary brain tumors and discuss the potential impact of such observation on patient stratification and on the possibility of developing appropriate targeted therapies using the UPR as therapeutic target.

    Brain metastasis, a common complication of non-small cell lung cancer (NSCLC) with an incidence rate of 30%-50%, significantly affects the patients' quality of life. The prognosis of patients of NSCLC with brain metastasis is extremely poor, the average median survival is only 1 m-2 m without treatment. The targeted therapy based on lung cancer driven gene is a new treatment. Besides, the immunotherapy which can enhance the effect of anti-cancer by simulating the immune system is a new approach. The combination of targeted therapy and immunotherapy can greatly benefit patients in clinical work. PMID:27561803

    It is often difficult to identify cancer tissue during brain cancer (glioma) surgery. Gliomas invade into areas of normal brain, and this cancer invasion is frequently not detected using standard preoperative magnetic resonance imaging (MRI). This results in enduring invasive cancer following surgery and leads to recurrence. A hand-held Raman spectroscopy is able to rapidly detect cancer invasion in patients with grade 2-4 gliomas. However, ambient light sources can produce spectral artifacts which inhibit the ability to distinguish between cancer and normal tissue using the spectral information available. To address this issue, we have demonstrated that artificial neural networks (ANN) can accurately classify invasive cancer versus normal brain tissue, even when including measurements with significant spectral artifacts from external light sources. The non-parametric and adaptive model used by ANN makes it suitable for detecting complex non-linear spectral characteristics associated with different tissues and the confounding presence of light artifacts. The use of ANN for brain cancer detection with Raman spectroscopy, in the presence of light artifacts, improves the robustness and clinical translation potential for intraoperative use. Integration with the neurosurgical workflow is facilitated by accounting for the effect of light artifacts which may occur, due to operating room lights, neuronavigation systems, windows, or other light sources. The ability to rapidly detect invasive brain cancer under these conditions may reduce residual cancer remaining after surgery, and thereby improve patient survival.

    Purpose: Many patients with brain metastases receive whole-brain radiotherapy (WBRT) alone. Using 10 Multiplication-Sign 3 Gy in 2 weeks is the standard regimen in most centers. Regarding the extraordinarily poor survival prognosis of elderly patients with multiple brain metastases, a shorter WBRT regimen would be preferable. This study compared 10 Multiplication-Sign 3 Gy with 5 Multiplication-Sign 4 Gy in elderly patients ({>=}65 years). Methods and Materials: Data from 455 elderly patients who received WBRT alone for brain metastases were retrospectively analyzed. Survival and local (= intracerebral) control of 293 patients receiving 10 Multiplication-Sign 3 Gy were compared with 162 patients receiving 5 Multiplication-Sign 4 Gy. Eight additional potential prognostic factors were investigated including age, gender, Karnofsky performance score (KPS), primary tumor, number of brain metastases, interval from tumor diagnosis to WBRT, extracerebral metastases, and recursive partitioning analysis (RPA) class. Results: The 6-month overall survival rates were 29% after 5 Multiplication-Sign 4 Gy and 21% after 10 Multiplication-Sign 3 Gy (p = 0.020). The 6-month local control rates were 12% and 10%, respectively (p = 0.32). On multivariate analysis, improved overall survival was associated with KPS {>=} 70 (p < 0.001), only one to three brain metastases (p = 0.029), no extracerebral metastasis (p = 0.012), and lower RPA class (p < 0.001). Improved local control was associated with KPS {>=} 70 (p < 0.001), breast cancer (p = 0.029), and lower RPA class (p < 0.001). Conclusions: Shorter-course WBRT with 5 Multiplication-Sign 4 Gy was not inferior to 10 Multiplication-Sign 3 Gy with respect to overall survival or local control in elderly patients. 5 Multiplication-Sign 4 Gy appears preferable for the majority of these patients.

The skeleton is the most common metastatic site but, following an improvement in survival, metastases in uncommon sites are being found more frequently in clinical practice, especially brain metastases. Despite the new drugs now available for metastatic castration resistant prostate cancer, no clinical evidence exists about their effectiveness on brain metastases. We describe the clinical history of 3 patients treated with cabazitaxel plus whole brain radiotherapy. These case reports demonstrate that cabazitaxel is highly active and well tolerated in brain metastases. PMID:24945013

    The CLEOPATRA trial reported the survival benefit of pertuzumab with trastuzumab plus docetaxel in HER2-positive metastatic breast cancer patients. However, there are a few case reports concerning the effects of a pertuzumab-containing regimen on brain metastases. A 55-year-old woman, who underwent curative surgery for breast cancer after neoadjuvant chemotherapy 5 years previously, developed repeated solitary brain metastasis in her right occipital lobe. Whole brain radiation therapy, stereotactic radiosurgery and 3 times of surgical resection were performed. Lapatinib and capecitabine plus tamoxifen were administered. The metastasis recurred in the stump of the previous surgery. Pertuzumab with trastuzumab plus docetaxel was initiated as second-line chemotherapy. A complete response of the brain metastasis was achieved, which persisted for 5 months. Pertuzumab with trastuzumab plus docetaxel was effective in reducing the brain metastases from breast cancer. Further studies are warranted to confirm the effect of this regimen on brain metastases. PMID:26116144

Methods and Materials: Twenty-nine patients who had solitary or multiple brain metastases without a detectable primary site underwent stereotactic radiosurgery between January 1990 and March 2007 at the University of Pittsburgh. The median patient age was 61.7 years (range, 37.9-78.7 years). The median target volume was 1.0 cc (range, 0.02-23.6 cc), and the median margin radiosurgical dose was 16 Gy (range, 20-70 Gy). Results: After radiosurgery, the local tumor control rate was 88.5%. Twenty four patients died and 5 patients were living at the time of this analysis. The overall median survival was 12 months. Actuarial survival rates from stereotactic radiosurgery at 1 and 2 years were 57.2% and 36.8%, respectively. Factors associated with poor progression-free survival included large tumor volume (3 cc or more) and brainstem tumor location. Conclusions: Radiosurgery is an effective and safe minimally invasive option for patients with brain metastases from an unknown primary site.

    Little progress has been made in the long-term management of glioblastoma multiforme (GBM), considered among the most lethal of brain cancers. Cytotoxic chemotherapy, steroids, and high-dose radiation are generally used as the standard of care for GBM. These procedures can create a tumor microenvironment rich in glucose and glutamine. Glucose and glutamine are suggested to facilitate tumor progression. Recent evidence suggests that many GBMs are infected with cytomegalovirus, which could further enhance glucose and glutamine metabolism in the tumor cells. Emerging evidence also suggests that neoplastic macrophages/microglia, arising through possible fusion hybridization, can comprise an invasive cell subpopulation within GBM. Glucose and glutamine are major fuels for myeloid cells, as well as for the more rapidly proliferating cancer stem cells. Therapies that increase inflammation and energy metabolites in the GBM microenvironment can enhance tumor progression. In contrast to current GBM therapies, metabolic therapy is designed to target the metabolic malady common to all tumor cells (aerobic fermentation), while enhancing the health and vitality of normal brain cells and the entire body. The calorie restricted ketogenic diet (KD-R) is an anti-angiogenic, anti-inflammatory and pro-apoptotic metabolic therapy that also reduces fermentable fuels in the tumor microenvironment. Metabolic therapy, as an alternative to the standard of care, has the potential to improve outcome for patients with GBM and other malignant brain cancers. PMID:25069036

    Major depression has a high incidence in patients with cancer, but treatment guidelines for this vulnerable population are missing and antidepressants seem to be less effective than in patients not affected by cancer. We report the case of a patient with bronchial cancer with a single temporo-occipital brain metastasis that had been treated by radiotherapy (whole-brain radiation, 40 Gy, followed by a stereotactic radiotherapy, 15 Gy). The patient developed a major depressive episode and was successfully treated with electroconvulsive therapy without relevant adverse events. This case further underscores the safety and effectiveness of electroconvulsive therapy after radiotherapy of the brain and demonstrates a viable alternative for severely depressed patients with cancer who do not adequately respond to psychotherapy or pharmacotherapy alone.

    Purpose: Patients with advanced cancer are referred to our Rapid Response Radiotherapy Program for quick access to palliative radiotherapy. The primary objective of this prospective study was to determine the physician expectations of the treatment outcomes for patients with brain metastases referred for whole brain radiotherapy (WBRT). The secondary objectives were to determine the factors influencing the expectations and to examine the accuracy of the physician-estimated patient survival. Methods and Materials: Patients were identified during a 17-month period. The referring physicians were sent a survey by facsimile to be completed and returned before the patient consultation. Information was sought on the patient's disease status, the physician's expectations of WBRT, the estimated patient survival and performance status, and physician demographic data. Results: A total of 137 surveys were sent out, and the overall response rate was 57.7%. The median patient age was 66 years (range, 35-87), 78.5% had multiple brain metastases, 42.3% had a controlled primary tumor, and 62.3% had extracranial disease. WBRT was thought to stabilize neurologic symptoms, improve quality of life, and allow for a Decadron (dexamethasone) taper by >=94.9% of the referring physicians; 87.0% thought WBRT would improve performance status; 77.9% thought it would improve neurologic symptoms; and 40.8% thought it would improve survival. The referring physicians estimated patient survival as a median of 6.0 months; however, the actual survival was a median of 2.5 months, for a median individual difference of 1.9 months (p < .0001). Conclusion: Physicians referring patients with brain metastases for consideration of WBRT are often overly optimistic when estimating the clinical benefit of the treatment and overestimate patient survival. These findings highlight the need for education and additional research in this field.

    Background Health care spending is known to be highly skewed, with a small subset of the population consuming a disproportionate amount of health care resources. Patients with cancer are high-cost users because of high incremental health care costs for treatment and the growing prevalence of cancer. The objectives of the present study included characterizing cancer-patient trajectories by cost, and identifying the patient and health system characteristics associated with high health system costs after cancer treatment. Methods This retrospective cohort study identified Ontario adults newly diagnosed with cancer between 1 April 2009 and 30 September 2010. Costs of health care use before, during, and after cancer episodes were used to develop trajectories of care. Descriptive analyses examined differences between the trajectories in terms of clinical and health system characteristics, and a logistic regression approach identified predictors of being a high-cost user after a cancer episode. Results Ten trajectories were developed based on whether patients were high- or low-cost users before and after their cancer episode. The most common trajectory represented patients who were low-cost in the year before cancer, survived treatment, and continued to be low-cost in the year after cancer (31.4%); stage ii cancer of the male genital system was the most common diagnosis within that trajectory. Regression analyses identified increases in age and in multimorbidity and low continuity of care as the strongest predictors of high-cost status after cancer. Conclusions Findings highlight an opportunity to proactively identify patients who might transition to high-cost status after cancer treatment and to remediate that transition. PMID:26985150

    Breast cancer is the most commonly diagnosed cancer among women, resulting in an estimated 40,000 deaths in 2014.1 Metastasis, a complex, multi-step process, remains the primary cause of death for these patients. Although the mechanisms involved in metastasis have not been fully elucidated, considerable evidence suggests that metastatic spread is mediated by rare cells within the heterogeneous primary tumor that acquire the ability to invade into the bloodstream. In the bloodstream, they can travel to distant sites, sometimes remaining undetected and in a quiescent state for an extended period of time before they establish distant metastases in the bone, lung, liver, or brain. These occult micrometastatic cells (circulating tumor cells, CTCs) are rare, yet their prognostic significance has been demonstrated in both metastatic and non-metastatic breast cancer patients. Because repeated tumor tissue collection is typically not feasible and peripheral blood draws are minimally invasive, serial CTC enumeration might provide "real-time liquid biopsy" snapshots that could be used to identify early-stage breast cancer patients with micrometastatic disease who are at risk for disease progression and monitor treatment response in patients with advanced disease. In addition, characterizing CTCs might aid in the development of novel, personalized therapies aimed at eliminating micrometastases. This review describes current CTC isolation, detection, and characterization strategies in operable breast cancer. PMID:27481009

    Breast cancer brain metastases remain a significant clinical problem. Chemotherapy is ineffective and a lack of treatment options result in poor patient outcomes. Targeted therapeutics have proven to be highly effective in primary breast cancer, but lack of molecular genomic characterization of metastatic brain tumors is hindering the development of new treatment regimens. Here we contribute to fill this void by reporting on gene copy number variation (CNV) in 10 breast cancer metastatic brain tumors, assayed by array comparative genomic hybridization (aCGH). Results were compared to a list of cancer genes verified by others to influence cancer. Cancer gene aberrations were identified in all specimens and pathway-level analysis was applied to aggregate data, which identified stem cell pluripotency pathway enrichment and highlighted recurring, significant amplification of SOX2, PIK3CA, NTRK1, GNAS, CTNNB1, and FGFR1. For a subset of the metastatic brain tumor samples (n=4) we compared patient-matched primary breast cancer specimens. The results of our CGH analysis and validation by alternative methods indicate that oncogenic signals driving growth of metastatic tumors exist in the original cancer. This report contributes support for more rapid development of new treatments of metastatic brain tumors, the use of genomic-based diagnostic tools and repurposed drug treatments. PMID:25970776

    When a patient with cancer develops a brain metastasis, death is usually imminent, but aggressive treatment in some patients with limited or no systemic disease yields long-term survival. In such patients, delayed deleterious effects of therapy are particularly tragic. We report 12 patients who developed delayed complications of whole brain radiotherapy (WBRT) given as sole treatment (4 patients) or in combination with surgical resection (8 patients). Within 5 to 36 months (median, 14) all patients developed progressive dementia, ataxia, and urinary incontinence causing severe disability in all and leading to death in 7. No patient had tumor recurrence when neurologic symptoms began. Cortical atrophy and hypodense white matter were identified by CT in all. Contrast-enhancing lesions were seen in 3 patients; 2 of the lesions yielded radionecrosis on biopsy. Autopsies on 2 patients revealed diffuse chronic edema of the hemispheric white matter in the absence of tumor recurrence. Corticosteroids and ventriculoperitoneal shunt offered significant but incomplete improvement in some patients. The total dose of WBRT was only 2,500 to 3,900 cGy, but daily fractions of 300 to 600 cGy were employed. We believe that these fractionation schedules, several of which are used commonly, predispose to delayed neurologic toxicity, and that more protracted schedules should be employed for the safe and efficacious treatment of good-risk patients with brain metastases. The incidence of WBRT-induced dementia was only 1.9 to 5.1% in the 2 populations reviewed here; however, this underestimates the incidence because only severely affected patients could be identified from chart review.

    Objectives The incidence of cancer among the indigenous Sami people of Northern Finland is lower than among the Finnish general population. The survival of Sami cancer patients is not known, and therefore it is the object of this study. Study design The cohort consisted of 2,091 Sami and 4,161 non-Sami who lived on 31 December 1978 in the two Sami municipalities of Inari and Utsjoki, which are located in Northern Finland and are 300–500 km away from the nearest central hospital. The survival experience of Sami and non-Sami cancer patients diagnosed in this cohort during 1979–2009 was compared with that of the Finnish patients outside the cohort. Methods The Sami and non-Sami cancer patients were matched to other Finnish cancer patients for gender, age and year of diagnosis and for the site of cancer. An additional matching was done for the stage at diagnosis. Cancer-specific survival analyses were made using the Kaplan–Meier method and Cox regression modelling. Results There were 204 Sami and 391 non-Sami cancer cases in the cohort, 20,181 matched controls without matching with stage, and 7,874 stage-matched controls. In the cancer-specific analysis without stage variable, the hazard ratio for Sami was 1.05 (95% confidence interval 0.85–1.30) and for non-Sami 1.02 (0.86–1.20), indicating no difference between the survival of those groups and other patients in Finland. Likewise, when the same was done by also matching the stage, there was no difference in cancer survival. Conclusion Long distances to medical care or Sami ethnicity have no influence on the cancer patient survival in Northern Finland. PMID:22765936

    We perform a clinical and numerical study of the progression of brain cancer tumor growth dynamics coupled with the effects of radiotherapy. We obtained clinical data from a sample of brain cancer patients undergoing radiotherapy and compare it to our numerical simulations to a mathematical model of brain tumor cell population growth influenced by radiation treatment. We model how the body biologically receives a physically delivered dose of radiation to the affected tumorous area in the form of a generalized LQ model, modified to account for the conversion process of sublethal lesions into lethal lesions at high radiation doses. We obtain good agreement between our clinical data and our numerical simulations of brain cancer progression given by the mathematical model, which couples tumor growth dynamics and the effect of irradiation. The correlation, spanning a wide dataset, demonstrates the potential of the mathematical model to describe the dynamics of brain tumor growth influenced by radiotherapy.

    Purpose: The aim of this study was to evaluate the efficacy, toxicity, and survival of whole-brain radiotherapy-treated (WBRT) and high-dose methylprednisolone (HDMP)-treated in elderly patients with primary central nervous system lymphoma (PCNSL). Methods and Materials: Patients with PCNSL who were 70 years and older received 1 g of methylprednisolone daily for 5 days, 30 days after WBRT. Patients then received 1 g of methylprednisolone every 28 days until progression. The primary endpoint was overall survival (OS) at 6 months. Results were compared with those in patients on the previous North Central Cancer Treatment Group (NCCTG) trial who received pre-WBRT cytoxan, adriamycin, vincristine, prednisone (CHOP) and high-dose cytarabine (CHOP-WBRT). A planned interim analysis was performed. The current regimen would be considered inactive if survival was not improved from patients treated with CHOP-WBRT. Results: Nineteen patients were accrued between 1998 and 2003. Median age was 76 years. Interim analysis revealed a 6-month survival of 33%, resulting in closure of the trial. Toxicity, OS, and event-free survival (EFS) were similar to those in patients more than 70 years of age who received CHOP-WBRT. The subgroup of patients who received HDMP had longer OS (12.1 vs. 7.0 months, p = 0.76) and EFS (11.7 vs. 4.0 months, p = 0.04) compared with the CHOP-WBRT patients alive 60 days after the start of treatment. Conclusions: Patients on-study long enough to receive HDMP had prolongation of OS and EFS compared to patients receiving CHOP-WBRT. Although the numbers of patients are too small for statistical conclusions, the HDMP regimen deserves further study.

    Purpose: Patients with brain metastases are often treated with whole brain radiation therapy (WBRT) for purposes of palliation. The treatment of those who experience subsequent intracranial disease progression can include a second course of WBRT, although there is controversy surrounding its safety and efficacy. This study examines the outcomes in patients at Massachusetts General Hospital who underwent reirradiation. Patients and Methods: We examined the medical records of 17 patients at Massachusetts General Hospital with brain metastases who were initially treated with WBRT between 2002 and 2008 and were subsequently retreated with a second course of WBRT. The median dose for the first course of WBRT was 35 Gy (range, 28-40 Gy), with a fraction size of 2 to 3 Gy (median, 2.5 Gy). The median dose at reirradiation was 21.6 Gy (range, 14-30 Gy), with a fraction size of 1.5 to 2 Gy (median, 1.8 Gy). Results: The second course of WBRT was administered upon radiographic disease progression in all patients. Of 10 patients with complete follow-up data, 8 patients experienced complete or partial symptom resolution, and 2 did not show clinical improvement. The time to radiographic progression was 5.2 months. The median overall survival for all patients after diagnosis of metastases was 24.7 months. The median survival time after initiation of reirradiation was 5.2 months (95% CI, 1.3-8.7). In 6 patients with stable extracranial disease, the median survival time after retreatment was 19.8 months (95% CI, 2.7-{infinity}), compared with 2.5 months (95% CI, 0.8-5.5) for those with extracranial disease progression (p = 0.05). Acute adverse reactions occurred in 70.5% of patients but were mild to moderate in severity. Conclusion: In select patients and especially those with stable extracranial disease, reirradiation may be an appropriate and effective intervention to provide symptomatic relief and slow intracranial disease progression. Side effects were minimal and did not

    Sexuality is a basic need for every human being as long as he or she is alive, irrespective of age or health status. Approximately 23,500 individuals are diagnosed with cancer each year in Israel and join the 120,000 cancer patients currently living in Israel. The results of cancer treatments are traditionally assessed and based on the outcome regarding mortality versus survival. An equally important aspect to be addressed in this assessment must relate to quality of life. One of the more painful insults to the quality of life of cancer patients relates to the deleterious effects on sexuality. This article aims to present physicians with the spectrum of sexuality-related issues which are encountered by cancer patients and their partners, starting from the moment of diagnosis, throughout the various stages of treatment and to provide basic knowledge. Many individuals contracting cancer have difficulty dealing with the issue of sexuality. They are typically embarrassed and feel uneasy when asking health care providers about such a non-life threatening issue. Partners similarly feel both shame and guilt. In many cases sexuality, intimacy and emotional attachment are important aspects and may be essential for survival. Addressing these issues during treatment can provide patients with a sense of security, avoiding embarrassment and further exacerbation of such problems. Unfortunately, little has been done to develop an optimal interventional program, although standard sexual treatments have often been applied. Prospective clinical research and outcomes are missing. The physician can use the well-known PLISSIT model (1978): to provide sexuality involvement on different levels. The very new BETTER model (2004) can help emphasize that cancer treatment and the disease have an influence on intimacy and sexuality. PMID:20070056

    Background Brain metastases (BM) are the most common form of intracranial cancer. The incidence of BM seems to have increased over the past decade. Recursive partitioning analysis (RPA) of data from three Radiation Therapy Oncology Group (RTOG) trials (1200 patients) has allowed three prognostic groups to be identified. More recently a simplified stratification system that uses the evaluation of three main prognostics factors for radiosurgery in BM was developed. Methods To analyze the overall survival rate (OS), prognostic factors affecting outcomes and to estimate the potential improvement in OS for patients with BM from breast cancer, stratified by RPA class and brain metastases score (BS-BM). From January 1996 to December 2004, 174 medical records of patients with diagnosis of BM from breast cancer, who received WBRT were analyzed. The surgery followed by WBRT was used in 15.5% of patients and 84.5% of others patients were submitted at WBRT alone; 108 patients (62.1%) received the fractionation schedule of 30 Gy in 10 fractions. Solitary BM was present in 37.9 % of patients. The prognostic factors evaluated for OS were: age, Karnofsky Performance Status (KPS), number of lesions, localization of lesions, neurosurgery, chemotherapy, absence extracranial disease, RPA class, BS-BM and radiation doses and fractionation. Results The OS in 1, 2 and 3 years was 33.4 %, 16.7%, and 8.8 %, respectively. The RPA class analysis showed strong relation with OS (p < 0.0001). The median survival time by RPA class in months was: class I 11.7, class II 6.2 and class III 3.0. The significant prognostic factors associated with better OS were: higher KPS (p < 0.0001), neurosurgery (P < 0.0001), single metastases (p = 0.003), BS-BM (p < 0.0001), control primary tumor (p = 0.002) and absence of extracranial metastases (p = 0.001). In multivariate analysis, the factors associated positively with OS were: neurosurgery (p < 0.0001), absence of extracranial metastases (p <0.0001) and RPA

    Long-term toxic effects of prophylactic cranial irradiation (PCI) on cognition in small cell lung cancer (SCLC) patients have not yet been well-established. The aim of our study was to examine the cognitive toxic effects together with brain structural changes in a group of long-term SCLC survivors treated with PCI. Eleven SCLC patients, who underwent PCI ≥ 2 years before, were compared with an age and education matched healthy control group. Both groups were evaluated using a neuropsychological battery and multimodal structural magnetic resonance imaging. Voxel-based morphometry and Tract-based Spatial Statistics were used to study gray matter density (GMD) and white matter (WM) microstructural changes. Cognitive deterioration was correlated with GMD and Fractional Anisotropy (FA). Finally, we carried out a single-subject analysis in order to evaluate individual structural brain changes. Nearly half of the SCLC met criteria for cognitive impairment, all exhibiting a global worsening of cognitive functioning. Patients showed significant decreases of GMD in basal ganglia bilaterally (putamen and caudate), bilateral thalamus and right insula, together with WM microstructural changes of the entire corpus callosum. Cognitive deterioration scores correlated positively with mean FA values in the corpus callosum. Single-subject analysis revealed that GMD and WM changes were consistently observed in nearly all patients. This study showed neuropsychological deficits together with brain-specific structural differences in long-term SCLC survivors. Our results suggest that PCI therapy, possibly together with platinum-based chemotherapy, was associated to permanent long-term cognitive and structural brain effects in a SCLC population.

    Endogenous lipoid pneumonia (EnLP) is an uncommon non-life-threatening inflammatory lung disease that usually occurs in patients with conditions such as lung cancers, primary sclerosing cholangitis, and undifferentiated connective tissue disease. Here we report a case of EnLP in a paralytic and cachectic patient with bronchopneumonia after brain injury. A 40-year-old man experienced a severe brain injury in an automobile accident. He was treated for 1 month and his status plateaued. However, he became paralyzed and developed cachexia and ultimately died 145 days after the accident. Macroscopically, multifocal yellowish firm nodules were visible on scattered gross lesions throughout the lungs. Histologically, many foam cells had accumulated within the alveoli and alveolar walls accompanied by a surrounding interstitial infiltration of lymphocytes. The findings were in accordance with a diagnosis of EnLP. Bronchopneumonia was also noted. To our knowledge, there have been few reports of EnLP associated with bronchopneumonia and cachexia after brain injury. This uncommon pathogenesis should be well recognized by clinicians and forensic pathologists. The case reported here should prompt medical staff to increase the nutritional status and fight pulmonary infections in patients with brain injury to prevent the development of EnLP. PMID:26097618

The aim of this study was to describe clinicopathologic features of patients with breast cancer brain metastasis (BCBM); to evaluate survival after diagnosis of BCBM; and to compare estrogen receptor (ER), progesterone receptor (PR), and HER2 expression in the paired primary and brain tumors. Materials and Methods. We identified 140 consecutive patients who underwent craniotomy for BCBM (either for diagnostic purpose or with therapeutic intent) at the University of Texas MD Anderson Cancer Center between 2002 and 2009. Results. Most patients had invasive ductal histology (91%), grade 3 tumors (67%), and positive axillary lymph node (64%). Of the tumors, 56% were ER-negative, 62% were PR-negative, 44% were HER2-positive, and 28% were triple negative (TN). Brain metastasis (BM) was solitary in 51% of patients. Median interval from breast cancer diagnosis to BM was 46 months; median survival after BM was 14.1 months. In the univariate analysis, younger age, solitary brain metastasis, and ER or PR positivity in the breast tumors were associated with longer survival. There was a statistical trend toward increased survival in HER2-positive patients compared with HER2-negative patients (18 vs. 11 months). In the multivariate analysis, predictors for longer survival included younger age, solitary brain lesion, and HER2 positivity in the breast cancer. Biomarkers were evaluated in paired primary and brain tumors in 35 patients for ER status, 34 for PR status, and 36 for HER2 status. Discordant rates were 28% for ER, 20% for PR, and 3% for HER2. Conclusion. Compared with unselected breast cancer patients at the same institution, patients with breast cancer who had brain metastases had a higher proportion of hormone receptor-negative, HER2-positive, and TN tumors. Younger age, solitary brain lesion, and HER2 expression were independent predictors of better survival in patients with BCBM. HER2 status was highly concordant between the paired primary and brain tumors

    Language cortex in the human brain shows high variability among normal individuals and may exhibit a considerable shift from its original position due to tumor growth. Mapping the precise location of language areas is important before surgery to avoid postoperative language deficits. In this paper, the Magnetoencephalography (MEG) recording and the MRI scanning of six brain tumorous subjects are used to localize the language specific areas. MEG recordings were performed during two silent reading tasks; silent word reading and silent picture naming. MEG source imaging is performed using distributed source modeling technique called CLARA ("Classical LORETA Analysis Recursively Applied"). Estimated MEG sources are overlaid on individual MRI of each patient to improve interpretation of MEG source imaging results. The results show successful identification of the essential language areas and clear definition of the time course of neural activation connecting them. PMID:26736340

    Up to 40% non-small cell lung cancer patients developed brain metastasis during progression. Multiple brain metastases are common in non-small cell lung cancer. The prognosis of brain metastasis is poor with median survival of less than 1 year. Radio therapy for brain metastases has gradually developed from whole brain radiotherapy (WBRT) to various radiation strategies. WBRT, surgery+WBRT, stereotactic radiotherapy+WBRT or WBRT with simultaneous integrated boost (SIB), etc. have better overall survival than those untreated patients. The damage of the cognitive function from WBRT has been realized recently, however, options of radiation strategies for long expected survival patients remain controversial. This paper will discuss different WBRT strategies and treatment side effects of non-small cell lung cancer with brain metastases. PMID:27118651

    The incidence of second malignant tumors is a clinically observed adverse late effect of radiation therapy, especially in organs close to the treatment site, receiving medium to high doses (>2.5 Gy). For pediatric patients, choosing the least toxic radiation modality is of utmost importance, due to their high radiosensitivity and small size. This study aims to evaluate the risk of second cancer incidence in the vicinity of the primary radiation field, for pediatric patients with brain/head and neck tumors and compare four treatment modalities: passive scattering and pencil beam scanning proton therapy (PPT and PBS), intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT). For a cohort of six pediatric patients originally treated with PPT, additional PBS, IMRT and VMAT plans were created. Dose distributions from these plans were used to calculate the excess absolute risk (EAR) and lifetime attributable risk (LAR) for developing a second tumor in soft tissue and skull. A widely used risk assessment formalism was employed and compared with a linear model based on recent clinical findings. In general, LAR was found to range between 0.01%-2.8% for PPT/PBS and 0.04%-4.9% for IMRT/VMAT. PBS was associated with the lowest risk for most patients using carcinoma and sarcoma models, whereas IMRT and VMAT risks were comparable and the highest among all modalities. The LAR for IMRT/VMAT relative to PPT ranged from 1.3-4.6 for soft tissue and from 3.5-9.5 for skull. Larger absolute LAR was observed for younger patients and using linear risk models. The number of fields used in proton therapy and IMRT had minimal effect on the risk. When planning treatments and deciding on the treatment modality, the probability of second cancer incidence should be carefully examined and weighed against the possibility of developing acute side effects for each patient individually.

    Psychodynamic psychotherapy is effective as an approach to understanding the psychological conflicts and the psychiatric symptoms of cancer patients as well as to planning useful psychological interventions. The author recommends that the psychotherapist who treats cancer patients be familiar with the following: 1) the natural course and treatment of the illness, 2) a flexible approach in accord with the medical status of the patient, 3) a common sense approach to defenses, 4) a concern with quality-of-life issues, and 5) counter- transference issues as they relate to the treatment of very sick patients. Case reports illustrate the unique problems facing psychotherapists who are treating cancer patients. Further, these cases show the effective use of psychodynamic principles to inform the therapist of successful psychotherapeutic interventions. PMID:9407471

    Background Surveys of the experience of cancer patients are increasingly being introduced in different countries and used in cancer epidemiology research. Sampling processes, post-sampling mortality and survey non-response can influence the representativeness of cancer patient surveys. Methods We examined predictors of post-sampling mortality and non-response among patients initially included in the sampling frame of the English Cancer Patient Experience Survey. We also compared the respondents’ diagnostic case-mix to other relevant populations of cancer patients, including incident and prevalent cases. Results Of 109,477 initially sampled cancer patients, 6273 (5.7%) died between sampling and survey mail-out. Older age and diagnosis of brain, lung and pancreatic cancer were associated with higher risk of post-sampling mortality. The overall response rate was 67% (67,713 respondents), being >70% for the most affluent patients and those diagnosed with colon or breast cancer and <50% for Asian or Black patients, those under 35 and those diagnosed with brain cancer. The diagnostic case-mix of respondents varied substantially from incident or prevalent cancer cases. Conclusions Respondents to the English Cancer Patient Experience Survey represent a population of recently treated cancer survivors. Although patient survey data can provide unique insights for improving cancer care quality, features of survey populations need to be acknowledged when analysing and interpreting findings from studies using such data.

    Schizophrenia has been the focus of intense neuroimaging research. Although its fundamental pathobiology remains elusive, neuroimaging studies provide evidence of abnormalities of cerebral structure and function in patients with schizophrenia. We used morphometry as a quantitative method for estimation of volume of brain structures. Seventy eight right-handed subjects aged 18-45 years were exposed to MRI-examination. Patients were divided into 3 groups: patients with schizophrenia, their relatives and healthy controls. The volumes of interested structures (caudate nucleus, putamen, ventricles, frontal and temporal lobe) were measured using T2-weighted MR-images. Correlations between structural differences and functional deficit were evaluated.

    Summary Brain metastasis is an end stage in breast cancer progression. Traditional treatment options have minimal efficacy, and overall survival is on the order of months. The incidence of brain metastatic disease is increasing with the improved management of systemic disease and prolongation of survival. Unfortunately, the targeted therapies that control systemic disease have diminished efficacy against brain lesions. There are reasons to be optimistic, however, as emerging therapies have shown promise in preclinical and early clinical settings. This review discusses recent advances in breast cancer brain metastasis therapy and potential approaches for successful treatment. PMID:25670078

    Purpose Basal-like breast tumors are typically (ER/PR/HER2) triple-negative and are associated with a high incidence of brain metastases and poor clinical outcomes. The molecular chaperone αB-crystallin is predominantly expressed in triple-negative breast cancer (TNBC) and contributes to an aggressive tumor phenotype in preclinical models. We investigated the potential role of αB-crystallin in brain metastasis in TNBC. Experimental Design αB-crystallin expression in primary breast carcinomas and brain metastases was analyzed by immunohistochemistry among breast cancer patients with brain metastases. αB-crystallin was overexpressed or silenced in two different TNBC cell lines. The effects on cell adhesion to human brain microvascular endothelial cells (HBMECs) or extracellular matrix proteins, transendothelial migration, and transmigration across a HBMEC/astrocyte co-culture blood-brain barrier (BBB) model were examined. Additionally, the effects of overexpressing or silencing αB-crystallin on brain metastasis in vivo were investigated using orthotopic TNBC models. Results In a cohort of women with breast cancer brain metastasis, αB-crystallin expression in primary breast carcinomas was associated with poor overall survival and poor survival after brain metastasis, even among TNBC patients. Stable overexpression of αB-crystallin in TNBC cells enhanced adhesion to HBMECs, transendothelial migration, and BBB transmigration in vitro, while silencing αB-crystallin inhibited these events. αB-crystallin promoted adhesion of TNBC cells to HBMECs at least in part through an α3β1 integrin-dependent mechanism. αB-crystallin overexpression promoted brain metastasis, while silencing αB-crystallin inhibited brain metastasis in orthotopic TNBC models. Conclusion αB-crystallin is a novel regulator of brain metastasis in TNBC and represents a potential biomarker and drug target for this aggressive disease. PMID:24132917

    Retrospective studies of breast cancer patients suggest that primary tumor Her-2 overexpression or trastuzumab therapy is associated with a devastating complication: the development of central nervous system (brain) metastases. Herein, we present Her-2 expression trends from resected human brain metastases and data from an experimental brain metastasis assay, both indicative of a functional contribution of Her-2 to brain metastatic colonization. Of 124 archival resected brain metastases from breast cancer patients, 36.2% overexpressed Her-2, indicating an enrichment in the frequency of tumor Her-2 overexpression at this metastatic site. Using quantitative real-time PCR of laser capture microdissected epithelial cells, Her-2 and epidermal growth factor receptor (EGFR) mRNA levels in a cohort of 12 frozen brain metastases were increased up to 5- and 9-fold, respectively, over those of Her-2-amplified primary tumors. Co-overexpression of Her-2 and EGFR was also observed in a subset of brain metastases. We then tested the hypothesis that overexpression of Her-2 increases the colonization of breast cancer cells in the brain in vivo. A subclone of MDA-MB-231 human breast carcinoma cells that selectively metastasizes to brain (231-BR) overexpressed EGFR; 231-BR cells were transfected with low (4- to 8-fold) or high (22- to 28-fold) levels of Her-2. In vivo, in a model of brain metastasis, low or high Her-2-overexpressing 231-BR clones produced comparable numbers of micrometastases in the brain as control transfectants; however, the Her-2 transfectants yielded 3-fold greater large metastases (>50 microm(2); P < 0.001). Our data indicate that Her-2 overexpression increases the outgrowth of metastatic tumor cells in the brain in this model system. PMID:17483330

    Fewer than 2% of patients with metastatic prostate cancer (pca) develop brain metastases. Autopsy series have confirmed the rarity of brain metastases. When present, brain metastases occur in end stage, once the pca is castrate-resistant and spread to other sites is extensive. Here, we present a rare case of a patient with pca who developed a solitary parenchymal brain metastasis as first site of relapse 9 years after radical therapy. The patient underwent craniotomy and excision of the tumour. A second recurrence was also isolated to the brain. In the literature, pca patients with brain metastases have a poor mean survival of 1–7.6 months. The patient in our case report experienced a relatively favourable outcome, surviving 19 months after his initial brain relapse. PMID:26715888

    There is an estimated 3 million women in the US living as breast cancer survivors and persistent cancer related fatigue (PCRF) disrupts the lives of an estimated 30% of these women. PCRF is associated with decreased quality of life, decreased sleep quality, impaired cognition and depression. The mechanisms of cancer related fatigue are not well understood; however, preliminary findings indicate dysfunctional activity in the brain as a potential factor. Here we investigate the relationship between PCRF on intrinsic resting state connectivity in this population. Twenty-three age matched breast cancer survivors (15 fatigued and 8 non-fatigued) who completed all cancer-related treatments at least 12 weeks prior to the study, were recruited to undergo functional connectivity magnetic resonance imaging (fcMRI). Intrinsic resting state networks were examined with both seed based and independent component analysis methods. Comparisons of brain connectivity patterns between groups as well as correlations with self-reported fatigue symptoms were performed. Fatigued patients displayed greater left inferior parietal lobule to superior frontal gyrus connectivity as compared to non-fatigued patients (P < 0.05 FDR corrected). This enhanced connectivity was associated with increased physical fatigue (P = 0.04, r = 0.52) and poor sleep quality (P = 0.04, r = 0.52) in the fatigued group. In contrast greater connectivity in the non-fatigued group was found between the right precuneus to the periaqueductal gray as well as the left IPL to subgenual cortex (P < 0.05 FDR corrected). Mental fatigue scores were associated with greater default mode network (DMN) connectivity to the superior frontal gyrus (P = 0.05 FDR corrected) among fatigued subjects (r = 0.82) and less connectivity in the non-fatigued group (r = -0.88). These findings indicate that there is enhanced intrinsic DMN connectivity to the frontal gyrus in breast cancer survivors with persistent fatigue. As

    More than 90% of cancer death is attributed to metastatic disease, and the brain is one of the major metastatic sites of melanoma, colon, renal, lung and breast cancers. Despite the recent advancement of targeted therapy for cancer, the incidence of brain metastasis is increasing. One reason is that most therapeutic drugs can't penetrate blood-brain-barrier and tumor cells find the brain as sanctuary site. In this review, we describe the pathophysiology of brain metastases to introduce the latest understandings of metastatic brain malignancies. This review also particularly focuses on non-coding RNAs and their roles in cancer brain metastasis. Furthermore, we discuss the roles of the extracellular vesicles as they are known to transport information between cells to initiate cancer cell-microenvironment communication. The potential clinical translation of non-coding RNAs as a tool for diagnosis and for treatment is also discussed in this review. At the end, the computational aspects of non-coding RNA detection, the sequence and structure calculation and epigenetic regulation of non-coding RNA in brain metastasis are discussed. PMID:26709907

    This is a report of brain cancer survival patterns in certain Area Development Districts (ADDs) in Kentucky, the state, and the nation. Brain cancer is of national and regional concern as it is a disease of high case fatality rates and relatively short survival. Comparisons for survival were made between the U.S.A. and the state. Kentucky has higher brain cancer mortality rates than the U.S.A., but significantly better cause-specific survival (p < 0.05). In order to examine within state variations for brain cancer survival, data organized for the fifteen ADDs from the state's central cancer registry were used. The analytic focus of this analysis were three regions expressly: the Purchase ADD (location of the Paducah Gaseous Diffusion Plant), the Green River ADD (the location of elevated brain cancer mortality rates), and the Kentucky River ADD (comprising counties that each have significantly more than the state average of persons living below the national poverty level). We found no evidence of lower survival for brain cancer among the poorer region of the state. The western districts were found to have lower cause-specific survival than the state (p < 0.05) and the U.S.A. Such a regional variation alerts population-based researchers to consider varying survival trends within the state's population. PMID:18979721

    Lung cancer is a clinically difficult disease with rising disease burden around the world. Unfortunately, most lung cancers present at a clinically advanced stage. Of these cancers, many also present with brain metastasis which complicates the clinical picture. This review summarizes current knowledge on the molecular basis of lung cancer brain metastases. We start from the clinical perspective, aiming to provide a clinical context for a significant problem that requires much deeper scientific investigation. We review new research governing the metastatic process, including tumor cell signaling, establishment of a receptive tumor niches in the brain and evaluate potential new therapeutic options that take advantage of these new scientific advances. Lung cancer remains the largest single cause of cancer mortality in the United States (Siegel et al., 2015). This continues to be the clinical picture despite significant advances in therapy, including the advent of targeted molecular therapies and newly adopted immunotherapies for certain subtypes of lung cancer. In the vast majority of cases, lung cancer presents as advanced disease; in many instances, this advanced disease state is intimately associated with micro and macrometastatic disease (Goldberg et al., 2015). For both non-small cell lung cancer and small cell lung cancer patients, the predominant metastatic site is the brain, with up to 68% of patients with mediastinal lymph node metastasis eventually demonstrating brain metastasis (Wang et al., 2009).The frequency (incidence) of brain metastasis is highest in lung cancers, relative to other common epithelial malignancies (Schouten et al., 2002). Other studies have attempted to predict the risk of brain metastasis in the setting of previously non-metastatic disease. One of the largest studies to do this, analyzing historical data from 1973 to 2011 using the SEER database revealed a 9% risk of patients with previously non-metastatic NSCLC developing brain

    The purpose of this study is to determine the characteristic clinical features, radiologic findings, and precipitating and prognostic factors in the patients with breast cancer and with 5-Fluorouracil (5-FU)-induced leukoencephalopathy. We reviewed the medical records of six breast cancer patients who developed leukoencephalopathy after chemotherapy which included 5-FU and also evaluated thorough neurological examinations including mini-mental status examination, cerebrospinal fluid studies, brain images and brain biopsies. Six patients exhibited slowly progressing neurologic symptoms characterized by the impairment of cognitive function, abulia, ataxic gait, and/or akinetic mutism. None of the patients had any specific causes or etiologic factors for leukoencephalopathy. Brain MRI in all patients showed diffuse periventricular white matter changes in the T2-weighted MR image. Brain biopsy in Patient 1 showed fragmented axonal fiber and minimally deprived myelination with many scattered macrophages. Five patients who treated with steroids at the onset of neurological symptoms showed clinical improvement, regardless of their age, sex, the pathology and stage of breast cancer, or the total dosage of chemotherapeutic agents. We conclude that leukoencephalopathy in these cases could be attributable to 5-FU neurotoxicity and suggest that the administration of steroids might be the treatment of choice. PMID:11410695

    Whole brain radiation is the standard treatment for patients with brain metastasis but unfortunately tumors can recover from radiation-induced damage with the help of the immune system. The hypothesis that differences in immunokines in the cerebrospinal fluid (CSF) pre- and post-irradiation could reveal tumor biology and correlate with outcome of patients with metastatic breast cancer to the brain is tested. Collected CSF samples were analyzed using Luminex's multiplexing assays to survey global immunokine levels while Enzyme-Linked Immunosorbent Assays were used to quantify each individual immunokines. Cluster analysis was performed to segregate patients based on their common immunokine profile and each cluster was correlated with survival and other clinical parameters. Breast cancer brain metastasis was found to have altered immunokine profiles in the CSF, and that Interleukin-1α expression was elevated after irradiation. Therefore, immunokine profiling in the CSF could enable cancer physicians to monitor the status of brain metastases.

    The incidence of brain metastases in patients with lung cancer has increased as a result of improved local and systemic control and better diagnosis from advances in brain imaging. Because brain metastases are responsible for life-threatening symptoms and serious impairment of quality of life, resulting in shortened survival, prophylactic cranial irradiation has been proposed in both small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC) to try to improve incidence of brain metastasis, survival, and eventually quality of life. Findings from randomised controlled trials and a meta-analysis have shown that prophylactic cranial irradiation not only reduces the incidence of brain metastases in patients with SCLC and with non-metastatic NSCLC, but also improves overall survival in patients with SCLC who respond to first-line treatment. Although prophylactic cranial irradiation is potentially associated with neurocognitive decline, this risk needs to be balanced against the potential benefit in terms of brain metastases incidence and survival. Several strategies to reduce neurotoxicity are being investigated. PMID:27396646

    Testicular cancer(TC)is the most common and curable cancer affecting men of reproductive age. Successful treatment approaches have resulted in longer life expectancy in TC survivors. The most frequently used treatment for TC is a combination of inguinal orchiectomy, and either radiotherapy or cisplatin-based chemotherapy. In many TC patients, sperm quality is already abnormal and there may even be a lack of viable spermatozoa at the time of diagnosis. Therefore, the effect of cancer treatment on fertility is a potentially significant issue. Fertility preservation in these men has become essential and needs to be discussed prior to the start of cancer treatment. The only currently established fertility preservation method is the cryopreservation of sperm before therapy. For most patients seeking cryopreservation, the semen sample is collected via masturbation. If the patient is unable to ejaculate for any reason, other techniques such as vibratory stimulation and electroejaculation can be performed. In azoospermic or severely oligozoospermic patients, testicular sperm extraction at the time of the inguinal orchiectomy is a useful technique for obtaining spermatozoa before cytotoxic therapy. We herein present an overview of the current topics on fertility in TC patients, including the effects of surgery, chemotherapy, and radiation therapy. We also describe the strategy for fertility preservation in these patients. PMID:25812494

    Allogeneic blood transfusion (ABT) therapy plays a major role in the case of patients with cancer. Packed red blood cells (PRBC) are given for increased oxygen-carrying capacity, platelets concentrates (PC) and fresh frozen plasma (FFP) for the cessation and prevention of bleeding due to thrombocytopenia and other defects of hemostasis associated with neoplasia. All these blood components can induce complications and/or adverse reactions in cancer patients including transfusion-associated graft versus host disease (TA-GVHD), transfusion transmitted diseases, alloimmunization to blood cell antigens, pulmonary decompensation, immunomodulation. Therefore, specific modifications such as leukocyte-reduction and irradiation of the blood components to be transfused in cancer patients should be introduced to reduce the risk of these complications. Patients undergoing hematopoietic progenitor cell (HPC) transplantation are a unique group and present complex concerns related to transfusion, including major and minor ABO incompatibility and chimeric blood cells. Therefore, transfusion for patients undergoing treatment with cellular therapies requires careful blood component selection. The process of HPC infusion itself carries many risks including DMSO toxicity and hemolytic reactions. In all areas of transfusion therapy, new advances such as pathogen inactivation and synthetic alternatives to blood components should help to increase the safety and tolerance of transfusion in cancer patients.

    Abstract Mycobacterium arupense is a slow-growing, nonchromogenic, acid-fast bacillus. Its clinical spectrum, epidemiology, and frequency of colonization versus true infection remain unknown. We evaluated the clinical significance of M arupense and positive cultures from cancer patients. We retrospectively reviewed records of all cancer patients treated at our institution between 2007 and 2014 to identify those who had positive cultures for M arupense. Mycobacterium arupense was identified by sequencing the 16S rRNA and hsp65 genes. A total of 53patients had positive cultures, 100% of which were isolated from respiratory specimens. Of these, 7 patients met the American Thoracic Society/Infectious Diseases Society of America criteria for a definitive diagnosis of M arupense infection, 14 cases were considered to be probable infections, and 29 cases were considered to be possible infections. Of the included patients, 13 received therapy for M arupense infection and 40 did not. The outcomes of treated and untreated patients did not differ significantly. No relapses of M arupense infection. In addition, there were no M arupense-related deaths in either group. In cancer patients, M arupense appears to be mostly a commensal organism rather than a pathogen. Patients who did or did not receive treatment had similar outcomes. Validation of these findings in a larger prospective trial is warranted. PMID:27057825

    There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high coprevalence of hypertension and cancer, since both diseases share the same risk factors, such as sedentary lifestyle, obesity, smoking, unhealthy diet and alcohol abuse. The use of chemotherapy and adjuvant drugs effective in the treatment of cancer increased the survival rate of these patients and, consequently, increased the incidence of hypertension. We described the association between the use of angiogenesis inhibitors (bevacizumab, sorafenib and sunitinib), corticosteroids, erythropoietin and non-steroidal anti-inflammatory drugs with the development of hypertension. We also described the relationship between hypertension and carotid baroreceptor injury secondary to cervical radiotherapy. Morbidity and mortality increased in patients with cancer and hypertension without proper antihypertensive treatment. We concluded that there is need for early diagnosis, effective monitoring and treatment strategies for hypertension in cancer patients in order to reduce cardiovascular morbidity and mortality.

    Gliomas, primary brain cancers, are characterized by remarkable invasiveness and fast growth. While they share many qualities with other solid tumors, gliomas have developed special mechanisms to convert the cramped brain space and other limitations afforded by the privileged central nervous system into pathophysiological advantages. In this review we discuss gliomas and other primary brain cancers in the context of acid-base regulation and interstitial acidification; namely, how the altered proton (H+) content surrounding these brain tumors influences tumor development in both autocrine and paracrine manners. As proton movement is directly coupled to movement of other ions, pH serves as both a regulator of cell activity as well as an indirect readout of other cellular functions. In the case of brain tumors, these processes result in pathophysiology unique to the central nervous system. We will highlight what is known about pH-sensitive processes in brain tumors in addition to gleaning insight from other solid tumors. PMID:24198789

    Cancer patients are regularly affected by malnutrition which often leads to a worsened quality of life and activity in daily living, more side effects and complications during anticancer treatment and shorter survival times. The early diagnosis and treatment of malnutrition are therefore relevant components of oncological treatment. The assessment of the nutritional status and determination of the body-mass-index should be done in every patient with cancer. The clinical examination delivers important findings and indications for malnutrition. Bioimpedance analysis can deliver additional objective information. The treatment of malnutrition should start early and follows a step-wise escalation reaching from nutritional counseling to enteral nutritional support to parenteral nutrition. PMID:26886037

    Pituitary metastases are uncommon complications of systemic cancer and account for only 1% of pituitary lesions. Breast cancer is one of the most common tumors to metastasize to the pituitary gland. A multidisciplinary approach that calls for close collaboration among oncologists, neurosurgeons, radiologists, and endocrinologists is mandatory for diagnosis and treatment of pituitary metastasis. From 2002 through 2013, 6 patients with pituitary metastases were treated at Shizuoka Cancer Center Hospital. The patients' age at presentation ranged from 45 to 75 years(average 59 years). Five of 6 patients had symptoms: anterior pituitary insufficiency in 4, diabetes insipidus in 3, and visual deficits in 2 patients. Five patients had other metastases at the time of presentation. Local irradiation to the metastatic lesion was adopted in 4, and whole brain irradiation was in 2 patients. In all cases, local control was achieved after irradiation, however, the pituitary insufficiency did not recover. Two of 4 patients treated with local irradiation suffered from meningeal dissemination within 5 months after treatment, and died at 8 and 11 months after diagnosis of pituitary metastasis, respectively. The patients treated with whole brain irradiation had longer survival periods. Early diagnosis, endocrinological management, and radiation therapy improve the quality of life in patients suffering from pituitary metastasis. Whole brain irradiation may be favorable in order to prevent meningeal dissemination. PMID:27166841

    2012-09-01

    Prevalence of hypogonadism in men with cancer has been reported between 40% and 90%, which is significantly higher than in the general population. Hypogonadism is likely to affect the quality of life in these patients by contributing to non-specific symptoms, including decreased energy, anorexia, sarcopenia, weight loss, depression, insomnia, fatigue, weakness, and sexual dysfunction. Pathogenesis of hypogonadism in cancer patients is thought to be multi-factorial. Inflammation may play an important role, but leptin, opioids, ghrelin, and high-dose chemotherapy through different mechanisms have all been implicated as the cause. Hypogonadism is also associated with poor survival in cancer patients. Data looking into the treatment of hypogonadal male cancer patients with testosterone are limited. However, improvements in body weight, muscle strength, lean body mass, and quality of life have been shown in hypogonadal men with other chronic diseases on testosterone replacement therapy. Prospective and interventional trials are needed to test the efficacy and safety of testosterone treatment in improving quality of life of these patients. PMID:22528986

    Purpose: Patients with brain metastases may experience treatment-related cognitive deficits. In this study, we prospectively assessed the self-reported cognitive abilities of patients with brain metastases from any solid primary cancer before and after irradiation of the brain. Methods and Materials: The treatment group (TG) consisted of adult patients (n=50) with brain metastases who received whole or partial irradiation of the brain without having received prior radiation therapy (RT). The control group (CG) consisted of breast cancer patients (n=27) without cranial involvement who were treated with adjuvant RT. Patients were recruited between May 2008 and December 2010. Self-reported cognitive abilities were acquired before RT and 6 weeks, 3 months, and 6 months after irradiation. The information regarding the neurocognitive status was collected by use of the German questionnaires for self-perceived deficits in attention (FEDA) and subjectively experienced everyday memory performance (FEAG). Results: The baseline data showed a high proportion of self-perceived neurocognitive deficits in both groups. A comparison between the TG and the CG regarding the course of self-reported outcomes after RT showed significant between-group differences for the FEDA scales 2 and 3: fatigue and retardation of daily living activities (P=.002) and decrease in motivation (P=.032) with an increase of attention deficits in the TG, but not in the CG. There was a trend towards significance in FEDA scale 1: distractibility and retardation of mental processes (P=.059) between the TG and the CG. The FEAG assessment presented no significant differences. An additional subgroup analysis within the TG was carried out. FEDA scale 3 showed significant differences in the time-related progress between patients with whole-brain RT and those receiving hypofractionated stereotactic RT (P=.025), with less decrease in motivation in the latter group. Conclusion: Self-reported attention declined in

    Aim. The aim of this study was to see the clinical, pathological, and demographic profile of young patients with stomach carcinoma besides association with p53. Patients and Methods. Prospective study of young patients with stomach carcinoma from January 2005 to December 2009. A total of 50 patients with age less than 40 years were studied. Results. Male female ratio was 1 : 1.08 in young patients and 2.5 : 1 in older patients. A positive family history of stomach cancer in the first degree relatives was present in 10% of young patients. Resection was possible only in 50% young patients. 26% young patients underwent only palliative gastrojejunostomy. The most common operation was lower partial gastrectomy in 68%. Amongst the intraoperative findings peritoneal metastasis was seen in 17.4% in young patients. 50% young patients presented in stage IV as per AJCC classification (P value .004; sig.). None of the patients presented as stage 1 disease in young group. Conclusion. Early detection of stomach carcinoma is very important in all patients but in young patients it is of paramount importance. PMID:24381753

    Brain metastases develop in one-third of patients with non-small-cell lung cancer and are associated with a dismal prognosis, irrespective of surgery or chemo-radiotherapy. Pathological markers for predicting outcomes after surgical resection and radiotherapy responsiveness are still lacking. Caveolin 1 has been associated with chemo- and radioresistance in various tumors, including non-small-cell lung cancer. Here, caveolin 1 expression was assessed in a series of 69 brain metastases from non-small-cell lung cancer and matched primary tumors to determine its role in predicting survival and radiotherapy responsiveness. Only caveolin 1 expression in brain metastasis was associated with poor prognosis and an increased risk of death (log rank test, p = 0.015). Moreover, in the younger patients (median age of <54 years), caveolin 1 expression neutralized the favorable effect of young age on survival compared with the older patients. Among the radiotherapy-treated patients, an increased risk of death was detected in the group with caveolin 1-positive brain metastasis (14 out of 22 patients, HR=6.839, 95% CI 1.849 to 25.301, Wald test p = 0.004). Overall, caveolin 1 expression in brain metastasis from non-small-cell lung cancer is independently predictive of worse outcome and radioresistance and could become an additional tool for personalized therapy in the critical subset of brain-metastatic non-small-cell lung cancer patients.

    Introduction: The utilization of the post-traumatic stress disorder (PTSD) diagnostic spectrum is currently being debated to categorize psychological adjustment in cancer patients. The aims of this study were to: (1) evaluate the presence of cancer-related traumatic dissociative symptomatology in a sample of cancer patients; (2) examine the correlation of cancer-related dissociation and sociodemographic and medical variables, anxiety, depression, and post-traumatic stress symptomatology; (3) investigate the predictors of cancer-related dissociation. Methods: Ninety-two mixed cancer patients (mean age: 58.94, ds = 10.13) recruited from two hospitals in northern Italy were administered a questionnaire on sociodemographic and medical characteristics, the Karnofsky Scale to measure the level of patient activity and medical care requirements, the Hospital Anxiety and Depression Scale (HADS) to evaluate the presence of anxiety and depression, the Impact of Event Scale Revised (IES-R) to assess the severity of intrusion, avoidance, and hypervigilance, and the Peritraumatic Dissociative Experiences Questionnaire (PDEQ) to quantify the traumatic dissociative symptomatology. Results: 31.5% of participants report a PDEQ score above the cutoff. The results indicated that dissociative symptomatology was positively correlated with HADS scores (HADS-Anxiety: r = 0.476, p < 0.001; HADS-Depression: r = 0.364, p < 0.001) and with IES-R scores (IES-R-Intrusion: r = 0.698, p < 0.001; IES-R-Avoidance: r = 0.619, p < 0.001; IES-R- Hypervigilance: r = 0.681, p < 0.001). A stepwise regression analysis was performed in order to find the predictors of cancer-related traumatic dissociative symptomatology. The results converged on a three predictor model revealing that IES-R-Intrusion, IES-R-Avoidance, and IES-R-Hyperarousal accounted for 53.9% of the explained variance. Conclusion: These findings allow us to hypothesize a specific psychological reaction which may be ascribed to the traumatic

    Treatment of brain cancers, especially high grade gliomas (WHO stage III and IV) is slowly making progress, but not as fast as medical researchers and the patients would like. Immunotherapy offers the opportunity to allow the patient's own immune system a chance to help eliminate the cancer. Immunotherapy's strength is that it efficiently treats relatively small tumors in experimental animal models. For some patients, immunotherapy has worked for them while not showing long-term toxicity. In this paper, we will trace the history of immunotherapy for brain cancers. We will also highlight some of the possible directions that this field may be taking in the immediate future for improving this therapeutic option. PMID:21437175

Treatment strategy in HIV-infected patients does not differ from general population. HIV-infected patients treated by chemo-radiotherapy are exposed to high-grade toxicities and should be closely monitored to deliver the optimal treatment. Close collaboration between oncologist and infectiologist is highly recommended to adjust antiretroviral therapy if necessary. PMID:25418596

    Leukemia and brain cancer patients under age 15 years, along with controls with respiratory illnesses who were matched to cases on age, sex, and year of diagnosis (1993-1999), were selected from 14 South Korean hospitals using the South Korean Medical Insurance Data System. Diagnoses were confirmed through the South Korean National Cancer Registry. Residential addresses were obtained from medical records. A newly developed prediction program incorporating a geographic information system that was modified by the results of actual measurements was used to estimate radio-frequency radiation (RFR) exposure from 31 amplitude modulation (AM) radio transmitters with a power of 20 kW or more. A total of 1,928 leukemia patients, 956 brain cancer patients, and 3,082 controls were analyzed. Cancer risks were estimated using conditional logistic regression adjusted for residential area, socioeconomic status, and community population density. The odds ratio for all types of leukemia was 2.15 (95% confidence interval (CI): 1.00, 4.67) among children who resided within 2 km of the nearest AM radio transmitter as compared with those resided more than 20 km from it. For total RFR exposure from all transmitters, odds ratios for lymphocytic leukemia were 1.39 (95% CI: 1.04, 1.86) and 1.59 (95% CI: 1.19, 2.11) for children in the second and third quartiles, respectively, versus the lowest quartile. Brain cancer and infantile cancer were not associated with AM RFR. PMID:17556764

    The aim of this review is to discuss the basic forms of neuropsychological rehabilitation for patients with traumatic brain injury (TBI). More broadly, we discussed cognitive rehabilitation therapy (CRT) which constitutes a fundamental component in therapeutic interaction at many centres worldwide. Equally presented is a comprehensive model of rehabilitation, the fundamental component of which is CRT. It should be noted that the principles of this approach first arose in Poland in the 1970s, in other words, several decades before their appearance in other programmemes. Taken into consideration are four factors conditioning the effectiveness of such a process: comprehensiveness, earlier interaction, universality and its individualized character. A comprehensive programmeme of rehabilitation covers: cognitive rehabilitation, individual and group rehabilitation with the application of a therapeutic environment, specialist vocational rehabilitation, as well as family psychotherapy. These training programmemes are conducted within the scope of the 'Academy of Life,' which provides support for the patients in their efforts and shows them the means by which they can overcome existing difficulties. Equally emphasized is the close cooperation of the whole team of specialists, as well as the active participation of the family as an essential condition for the effectiveness of rehabilitation and, in effect, a return of the patient to a relatively normal life. Also presented are newly developing neurothechnologies and the neuromarkers of brain injuries. This enables a correct diagnosis to be made and, as a result, the selection of appropriate methods for neuropsychological rehabilitation, including neurotherapy. PMID:26094541

    In addition to radial glial cells of neurohistogenesis, immature astrocytes with stem-cell-like properties cordon off emerging functional patterns in the developing brain. Astrocytes also can be stem cells during adult neurogenesis, and a proposed potency of injury-associated reactive astrocytes has recently been substantiated. Astrocytic cells might additionally be involved in cancer stem cell-associated gliomagenesis. Thus, there are distinguishing roles for stem-cell-like astrocytes during brain development, in neurogenic niches in the adult, during attempted reactive neurogenesis after brain injury or disease and during brain tumorigenesis.

    Chemotherapy has become a third major treatment option for patients with brain tumors, in addition to surgery and radiotherapy. The role of chemotherapy in the treatment of gliomas is no longer limited to recurrent disease. Temozolomide has become the standard of care in newly diagnosed glioblastoma. Several ongoing trials seek to define the role of chemotherapy in the primary care of other gliomas. Some of these studies are no longer only based on histological diagnoses, but take into consideration molecular markers such as MGMT promoter methylation and loss of genetic material on chromosomal arms 1p and 19q. Outside such clinical trials chemotherapy is used in addition to radiotherapy, e.g., in anaplastic astrocytoma, medulloblastoma or germ cell tumors, or as an alternative to radiotherapy, e.g., in anaplastic oligodendroglial tumors or low-grade gliomas. In contrast, there is no established role for chemotherapy in other tumors such as ependymomas, meningiomas or neurinomas. Primary cerebral lymphomas are probably the only brain tumors which can be cured by chemotherapy alone and only by chemotherapy. The chemotherapy of brain metastases follows the recommendations for the respective primary tumors. Further, strategies of combined radiochemotherapy using mainly temozolomide or topotecan are currently explored. Leptomeningeal metastases are treated by radiotherapy or systemic or intrathecal chemotherapy depending on their pattern of growth. PMID:18253773

    We report a case of pneumatosis cystoides intestinalis (PCI) in a patient with lung cancer. A 60-year-old woman was admitted with multiple lung tumors and multiple brain tumors. She was given steroid hormones to reduce her brain edema. Total resection of a brain tumor yielded a pathological diagnosis of metastatic squamous cell carcinoma. During treatment, X-ray and CT images revealed intestinal pneumatosis and free air in the abdominal cavity, but a physical examination revealed no abnormal findings. She was given a diagnosis of PCI, and received conservative treatment. Her intestinal gas cysts and intra-abdominal free air disappeared spontaneously. PCI is an uncommon but important condition in which gas is found in a linear or cystic form in the submucosa or subserosa of the bowel wall. It is important to consider PCI as a possible complication in lung cancer patients who are given steroid hormones and systemic chemotherapy in the long-term. PMID:21226307

    Brain metastasis is a significant cause of morbidity and mortality and a critical complication of non-central nervous system primary carcinoma. The present study describes the clinical case of a 46-year-old male with lung cancer and life-threatening brain metastases. The patient was diagnosed with lung cancer with a clinical stage of T2N0M1 (stage IV). Six months after the initial diagnosis and administration of conformal radiotherapy combined with three cycles of chemotherapy, an enhanced computed tomography (CT) scan of the brain revealed abnormalities with double-dosing of intravenous contrast. The CT scan identified >24 lesions scattered in the whole brain. The patient was treated with three-fraction Cyberknife radiotherapy at 22 Gy, delivered to the brain metastases at the Center for Tumor Treatment of People’s Liberation Army 107th Hospital. Following CyberKnife therapy, a CT scan of the brain revealed that most of the tumors had disappeared with almost no residual traces. The stereotactic radiosurgery (SRS) conducted using CyberKnife, an image-guided frameless robotic technology for whole-body radiosurgery, had produced a marked response. The present case report demonstrates that CyberKnife therapy plays a significant role in the management of multiple meta-static brain tumors. PMID:24137362

    Brain metastasis from uterine cervical cancer is rare, with an incidence of 0.5%, and usually occurs late in the course of the disease. We report a case of uterine cervical cancer with brain metastasis as the initial site of presentation. A 50-year-old woman with headache, vertigo, amnesia and loss of appetite was admitted for persistent vomiting. Contrast enhanced computed tomography showed a solitary right frontal cerebral lesion with ring enhancement and uterine cervical tumor. She was diagnosed with uterine cervical squamous cell carcinoma with parametrium invasion and no other distant affected organs were detected. The cerebral lesion was surgically removed and pathologically proved to be metastasis of uterine cervical squamous cell carcinoma. The patient underwent concurrent chemoradiotherapy, followed by cerebral radiation therapy, but multiple metastases to the liver and lung developed and the patient died 7 months after diagnosis of brain metastasis.

    There are many elements to the science that drives the clinical care of patients with brain metastases. Although part of an understanding that continues to evolve, a number of key historical misconceptions remain that commonly drive physicians' and researchers' attitudes and approaches. By understanding how these relate to current practice, we can better comprehend our available science to provide both better research and care. These past misconceptions include: Misconception 1: Once a primary cancer spreads to the brain, the histology of that primary tumor does not have much impact on response to chemotherapy, sensitivity to radiation, risk of further brain relapse, development of additional metastatic lesions, or survival. All tumor primary histologies are the same once they spread to the brain. They are the same in terms of the number of tumors, radiosensitivity, chemoresponsiveness, risk of further brain relapse, and survival. Misconception 2: The number of brain metastases matters. This number matters in terms of subsequent brain relapse, survival, and cognitive dysfunction; the precise number of metastases can also be used as a limit in determining which patients might be eligible for a particular treatment option. Misconception 3: Cancer in the brain is always a diffuse problem due to the presence of micrometastases. Misconception 4: Whole-brain radiation therapy invariably causes disabling cognitive dysfunction if a patient lives long enough. Misconception 5: Most brain metastases are symptomatic. Thus, it is not worth screening patients for brain metastases, especially because the impact on survival is minimal. The conduct and findings of past clinical research have led to conceptions that affect clinical care yet appear limiting. PMID:24662510

    Maitake mushroom (Grifola frondosa) MD-fraction containing beta-1,6 glucan with beta-1,3 branched chains has previously exhibited strong anticancer activity by increasing immune-competent cell activity.1,2 In this non-random case series, a combination of MD-fraction and whole maitake powder was investigated to determine its effectiveness for 22- to 57-year-old cancer patients in stages II-IV. Cancer regression or significant symptom improvement was observed in 58.3 percent of liver cancer patients, 68.8 percent of breast cancer patients, and 62.5 percent of lung cancer patients. The trial found a less than 10-20 percent improvement for leukemia, stomach cancer, and brain cancer patients. Furthermore, when maitake was taken in addition to chemotherapy, immune-competent cell activities were enhanced 1.2-1.4 times, compared with chemotherapy alone. Animal studies have supported the use of maitake MD-fraction for cancer. PMID:12126464

    Brain metastasis is a common cause of mortality in cancer patients, yet potential therapeutic targets remain largely unknown. The type I insulin-like growth factor receptor (IGF-IR) is known to play a role in the progression of breast cancer and is currently being investigated in the clinical setting for various types of cancer. The present study demonstrates that IGF-IR is constitutively autophosphorylated in brain-seeking breast cancer sublines. Knockdown of IGF-IR results in a decrease of phospho-AKT and phospho-p70s6k, as well as decreased migration and invasion of MDA-MB-231Br brain-seeking cells. In addition, transient ablation of IGFBP3, which is overexpressed in brain-seeking cells, blocks IGF-IR activation. Using an in vivo experimental brain metastasis model, we show that IGF-IR knockdown brain-seeking cells have reduced potential to establish brain metastases. Finally, we demonstrate that the malignancy of brain-seeking cells is attenuated by pharmacological inhibition with picropodophyllin, an IGF-IR-specific tyrosine kinase inhibitor. Together, our data suggest that the IGF-IR is an important mediator of brain metastasis and its ablation delays the onset of brain metastases in our model system. PMID:24039934

    Bone and brain metastases are a very common secondary localization of disease in patients with lung cancer. The prognosis of these patients is still poor with a median survival of less than 1 year. Current therapeutic approaches include palliative radiotherapy and systemic therapy with chemotherapy and targeted agents. For bone metastasis, zoledronic acid is the most commonly used bisphosphonate to prevent, reduce the incidence and delay the onset of skeletal-related events (SREs). Recently, denosumab, a fully human monoclonal antibody directed against the receptor activator of nuclear factor κB (RANK) ligand inhibiting the maturation of pre-osteoclasts into osteoclasts, showed increased time to SREs and overall survival compared with zoledronic acid. The treatment of brain metastasis is still controversial. Available standard therapeutic options, such as whole brain radiation therapy and systemic chemotherapy, provide a slight improvement in local control, overall survival and symptom relief. More recently, novel target agents such as the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) erlotinib, gefitinib and afatinib have shown activity in patients with brain metastasis. Inter alia, in patients harboring EGFR mutations, the administration of EGFR TKIs is followed by a response rate of 70–80%, and a longer progression-free and overall survival than those obtained with standard chemotherapeutic regimens. This review is focused on the evidence for therapeutic strategies in bone and brain metastases due to lung cancer. PMID:24790650

    Ionizing radiation used in treating the head and neck area produces oral side effects such as mucositis, salivary changes, trismus and radiation caries. Sequelae of cancer chemotherapy often include oral stomatitis, myelosuppression and immunosuppression. Infections of dental origin in compromised patients are potentially lethal. Specific programs to eliminate dental pathology before radiation and chemotherapy, and to maintain oral hygiene during and after therapy, will minimize these complications.

    Breast cancer, after lung cancer, is the second major cause of brain metastases. In breast cancer, the prognosis is closely linked to the molecular subtype of the primary tumor. Targeted therapies, with or without cytotoxic treatment, have significantly modified overall survival in these patients. We report, the case of a patient suffering from breast cancer with brain metastasis in whom the biological documentation of the metastatic disease permitted to tailor the systemic treatment. Analysis of the surgical specimen revealed an immunohistochemical HER2 positive staining, which was not found in the primary tumor and therefore warranted trastuzumab administration. Another interesting insight based on this case report was to underline the phenotypic heterogeneity of the metastatic disease and its potential dynamic course as illustrated by the dissociated response to trastuzumab on body TEP-TDM in this particular patient. This case report also highlights the new place of the neurosurgeon in brain metastases management, not only as a participant in local treatment but also as a physician who is in fact involved in the delineation of the global oncological strategy in these patients as well as medical oncologists and radiation oncologists.

    The patients referred for fertility preservation owing to a malignant disease do not represent the typical population of subfertile patients treated in IVF units. Cancer may affect multiple tissues throughout the body and can result in a variety of complications during controlled ovarian stimulation. Determination of the controlled ovarian stimulation protocol and gonadotropin dose for oocyte/embryo cryopreservation requires an individualized assessment. This review highlights the new protocols that are emerging to reduce time constraints and emphasizes management considerations to decrease complications. PMID:23635348

    Tyrosine kinase inhibitors (TKIs) of epidermal growth factor receptor (EGFR) were previously the standard first-line treatments for lung cancers with activating EGFR mutations. The first-generation reversible EGFR TKIs, gefitinib and erlotinib, demonstrated substantial efficacy in the treatment of brain metastases from EGFR-mutated lung adenocarcinoma. However, the efficacy of afatinib, the second-generation irreversible EGFR TKI, as the first-line treatment in lung adenocarcinoma patients with brain metastasis has yet to be evaluated.Here, we report cases of 3 patients who received afatinib alone as the first-line treatment in combination with whole-brain radiotherapy or following surgical resection of brain metastases. All 3 patients had EGFR L858R mutation. The first patient had lung adenocarcinoma with brain metastasis and no neurologic symptoms. After consultation, she received afatinib as a first-line treatment. Chest computed tomography and brain magnetic resonance imaging (MRI) showed partial response. The second patient had lung adenocarcinoma accompanied with a metastatic brain lesion associated with seizures. This patient received whole-brain radiotherapy and afatinib treatment following brain MRI and subsequently showed significant regression of the brain metastasis. The third patient had strabismus of the right eye, and brain MRI showed a single tumor at the cerebellar pontine angle. This patient underwent surgical resection of the tumor followed by afatinib treatment. He refused adjuvant radiotherapy after surgery for brain metastasis. The brain MRI showed no recurrent brain metastasis, and the patient had relatively less neurologic deficiency.This series of 3 cases indicate that afatinib may be an appropriate first-line treatment alternative in patients having lung adenocarcinoma with EGFR mutations. Further retrospective analyses and prospective clinical trials are required to substantiate the efficacy of afatinib in the treatment of brain

    Adjuvant chemotherapy is associated with improvements in long-term cancer survival. However, reports of cognitive impairment following treatment emphasize the importance of understanding the long-term effects of chemotherapy on brain functioning. Cognitive deficits found in chemotherapy patients suggest a change in brain functioning that affects specific cognitive domains such as attentional processing and executive functioning. This study examined the processes potentially underlying these changes in cognition by examining brain functional connectivity pre- and post-chemotherapy in women with breast cancer. Functional connectivity examines the temporal correlation between spatially remote brain regions in an effort to understand how brain networks support specific cognitive functions. Nine women diagnosed with breast cancer completed a functional magnetic resonance imaging (fMRI) session before chemotherapy, one month after, and one year after the completion of chemotherapy. Seed-based functional connectivity analyses were completed using seeds in the intraparietal sulcus (IPS) to examine connectivity in the dorsal anterior attention network and in the posterior cingulate cortex (PCC) to examine connectivity in the default mode network. Results showed decreased functional connectivity one month after chemotherapy that partially returned to baseline at one year in the dorsal attention network. Decreased connectivity was seen in the default mode network at one month and one year following chemotherapy. In addition, increased subjective memory complaints were noted at one month and one year post-chemotherapy. These findings suggest a detrimental effect of chemotherapy on brain functional connectivity that is potentially related to subjective cognitive assessment. PMID:23852814

    Overexpression of human epidermal growth factor receptor 2 (HER2) is found in about 20% of breast cancer patients. With treatment using trastuzumab, an anti-HER2 monoclonal antibody, systemic control is improved. Nonetheless, the incidence of brain metastasis does not be improved, rather seems to be increased in HER2-positive breast cancer. The mainstay treatment for brain metastases is radiotherapy. According to the number of metastatic lesions and performance status of patients, radiosurgery or whole brain radiotherapy can be performed. The concurrent use of a radiosensitizer further improves intracranial control. Due to its large molecular weight, trastuzumab has a limited ability to cross the blood-brain barrier. However, small tyrosine kinase inhibitors such as lapatinib, has been noted to be a promising agent that can be used as a radiosensitizer to affect HER2-positive breast cancer. This review will outline general management of brain metastases and will focus on preclinical findings regarding the radiosensitizing effect of small molecule HER2 targeting agents. PMID:27104161

    Background Malignant brain tumors are unpredictable and incurable, with 5-year survival rates less than 30%. The poor prognosis combined with intensive treatment necessitates the inclusion of complementary and supportive therapies that optimize quality of life and reduce treatment-related declines in health. Exercise therapy has been shown to be beneficial in other cancer populations, but no evidence is available for brain cancer survivors. Therefore, we report results from 2 preliminary cases. Methods Two female patients diagnosed with glioblastoma multiforme and oligodendroglioma participated in a structured and supervised 12-week exercise program. The program consisted of two 1-hour resistance and aerobic exercise sessions per week and additional self-managed aerobic sessions. Outcome measures of strength, cardiovascular fitness, and several psychological indicators (depression, anxiety, and quality of life) were recorded at baseline, after 6 weeks and at the conclusion of the intervention. Results Exercise was well tolerated; both participants completed all 24 sessions and the home-based component with no adverse effects. Objective outcome measures displayed positive responses relating to reduced morbidity. Similar positive responses were found for psychological outcomes. Scores on the Hospital Anxiety and Depression Scale showed clinically meaningful improvements in depression and total distress. Conclusion These findings provide initial evidence that, despite the difficulties associated with brain cancer treatment and survivorship, exercise may be safe and beneficial and should be considered in the overall management of patients with brain cancer.

    The prognosis associated with brain metastasis arising from breast cancer is very poor. Eribulin is a microtubule dynamic inhibitor synthesized from halichondrin B, a natural marine product. In a phase III study (EMBRACE), eribulin improved overall survival in patients with heavily pretreated metastatic breast cancers. However, these studies included few patients with brain metastases. Metastatic brain tumors (MBT) were detected during first-line palliative chemotherapy in a 43-year-old woman with breast cancer metastasis to the lung and mediastinal nodes; the genetic subtype was luminal B-like human epidermal growth factor receptor 2 (HER2)-negative. Whole brain radiotherapy (WBRT) followed by eribulin treatment continuously decreased the size, and induced regression, of the MBT with systemic disease stability for 12 months. Another 48-year-old woman with metastatic breast cancer (HER2+ subtype) presented with MBT. Following surgical resection of the tumor, eribulin with concurrent WBRT showed regression of the MBT without systemic progression for 18 months. PMID:27382400

    2011-01-01

    Introduction Activation status of the phosphatidylinositol 3-kinase (PI3K) pathway in breast cancer brain metastases (BCBMs) is largely unknown. We examined expression of phospho(p)-AKT, p-S6, and phosphatase and tensin homologue (PTEN) in BCBMs and their implications for overall survival (OS) and survival after BCBMs. Secondary analyses included PI3K pathway activation status and associations with time to distant recurrence (TTDR) and time to BCBMs. Similar analyses were also conducted among the subset of patients with triple-negative BCBMs. Methods p-AKT, p-S6, and PTEN expression was assessed with immunohistochemistry in 52 BCBMs and 12 matched primary BCs. Subtypes were defined as hormone receptor (HR)+/HER2-, HER2+, and triple-negative (TNBC). Survival analyses were performed by using a Cox model, and survival curves were estimated with the Kaplan-Meier method. Results Expression of p-AKT and p-S6 and lack of PTEN (PTEN-) was observed in 75%, 69%, and 25% of BCBMs. Concordance between primary BCs and matched BCBMs was 67% for p-AKT, 58% for p-S6, and 83% for PTEN. PTEN- was more common in TNBC compared with HR+/HER2- and HER2+. Expression of p-AKT, p-S6, and PTEN- was not associated with OS or survival after BCBMs (all, P > 0.06). Interestingly, among all patients, PTEN- correlated with shorter time to distant and brain recurrence. Among patients with TNBC, PTEN- in BCBMs was associated with poorer overall survival. Conclusions The PI3K pathway is active in most BCBMs regardless of subtype. Inhibition of this pathway represents a promising therapeutic strategy for patients with BCBMs, a group of patients with poor prognosis and limited systemic therapeutic options. Although expression of the PI3K pathway did not correlate with OS and survival after BCBM, PTEN- association with time to recurrence and OS (among patients with TNBC) is worthy of further study.

    The relation of brain cancer and mortality from leukaemia to electrical occupations was investigated in a case-control study based on all deaths in 1985 and 1986 in the 16 states in the United States that report occupational data from death certificates to the national vital statistics registry. The case series comprised all 2173 men who died of primary brain cancer (International Classification of Diseases-9 ((ICD-9) code 191) and all 3400 who died of leukaemia (ICD-9 codes 204-208). Each was matched with 10 controls who died of other causes in the same year. Men employed in any electrical occupation had age race adjusted odds ratios (ORs) of 1.4 (95% confidence interval (CI) 1.1-1.7) for brain cancer and 1.0 (95% CI 0.8-1.2) for leukaemia, compared with men in all other occupations. Brain cancer odds ratios were larger for electrical engineers and technicians (OR 2.7, 95% CI 2.1-3.4), telephone workers (OR 1.6, 95% CI 1.1-2.4), electric power workers (OR 1.7, 95% CI 1.1-2.7), and electrical workers in manufacturing industries (OR 2.1, 95% CI 1.3-3.4). There was some evidence of excess leukaemia among the same groups (ORs of 1.1-1.5) despite absence of an association for all electrical workers. The excess of deaths from brain cancer was concentrated among men aged 65 or older, whereas leukaemia was associated with electrical work only among younger decedents and those with acute lymphocytic leukaemia. These results from a large and geographically diverse population corroborate reports of increased mortality from brain cancer among electrical workers, but gives only limited support to suggestions of excess deaths from leukaemia.

    Background Bevacizumab is effective for the treatment of non-small cell lung cancer (NSCLC). Ongoing trials are exploring the safety of bevacizumab in patients with inactive, previously treated brain metastases. However, bevacizumab safety and efficacy in the treatment of active brain metastases is unknown. Bevacizumab received accelerated FDA approval for progressive glioblastoma, a primary brain tumor, because of high response rates and low incidence of intracranial hemorrhage. Methods We retrospectively identified patients treated with bevacizumab for active (treatment naïve or progressive) central nervous system (CNS) metastases from NSCLC. MRI scans performed at least 6 weeks after initiating bevacizumab were assessed for response. Results There were six patients, four women and two men with a median age of 60 years (range 59–77) at initiation of bevacizumab. Five patients had progressive CNS metastases despite prior treatment including surgery, radiotherapy, and/or chemotherapy; one patient had treatment-naïve brain metastases. Two patients had leptomeningeal metastases, isolated or coexistent with parenchymal brain metastases in one patient each. Bevacizumab was administered alone to one patient and in combination with various cytotoxic chemotherapies in the others. Toxicity included an asymptomatic (Grade 1) intra-tumoral hemorrhage which occurred in one of three patients receiving concurrent anticoagulation with bevacizumab. There was no recurrent CNS bleeding in two patients with a prior history of such hemorrhage. Best response (RECIST) was partial in two, stable disease in three, and progression in one. Median progression-free survival (PFS) was 4.7 months and median overall survival (OS) was 14.1 months following initiation of bevacizumab. Clinical benefit was also observed in the form of improved symptoms and reduced corticosteroid requirements. Conclusions Bevacizumab should be used with caution in patients with active CNS metastases pending

    Purpose The blood–brain barrier (BBB) essentially restricts therapeutic drugs from entering into the brain. This study tests the hypothesis that brain endothelial cell derived exosomes can deliver anticancer drug across the BBB for the treatment of brain cancer in a zebrafish (Danio rerio) model. Materials and Methods Four types of exosomes were isolated from brain cell culture media and characterized by particle size, morphology, total protein, and transmembrane protein markers. Transport mechanism, cell uptake, and cytotoxicity of optimized exosome delivery system were tested. Brain distribution of exosome delivered anticancer drugs was evaluated using transgenic zebrafish TG (fli1: GFP) embryos and efficacies of optimized formations were examined in a xenotransplanted zebrafish model of brain cancer model. Results Four exosomes in 30–100 diameters showed different morphologies and exosomes derived from brain endothelial cells expressed more CD63 tetraspanins transmembrane proteins. Optimized exosomes increased the uptake of fluorescent marker via receptor mediated endocytosis and cytotoxicity of anticancer drugs in cancer cells. Images of the zebrafish showed exosome delivered anticancer drugs crossed the BBB and entered into the brain. In the brain cancer model, exosome delivered anticancer drugs significantly decreased fluorescent intensity of xenotransplanted cancer cells and tumor growth marker. Conclusions Brain endothelial cell derived exosomes could be potentially used as a carrier for brain delivery of anticancer drug for the treatment of brain cancer. PMID:25609010

    Breast cancer is the second most common source of brain metastases (BM). The incidence of BM in breast cancer patients has increased over the past decade, especially among patients with HER-2-positive breast cancer. This is probably due to how aggressive the HER-2-positive disease is but also to the prolongation of survival obtained with current treatments, which allow good control of extracranial disease but are unable to cross the blood-brain barrier. At present, whole-brain radiotherapy, surgery and radiosurgery/stereotactic radiotherapy represent the cornerstone of treatment for BM, while the role of pharmacological therapy remains uncertain. Lapatinib demonstrated activity against BM from HER-2-positive breast cancer in small Phase II and retrospective studies, mainly in combination with capecitabine, and cases of dramatic responses to such treatment are present in literature. In this review we focus on the available clinical data regarding the treatment of BM from HER-2-positive breast cancer and on new concepts about the treatment and evaluation of the CNS response.

    Breast cancer is the third most common illness in the world and the most frequent malignant disease with women. Cytotoxic therapy is connected to significant psychiatric adverse effects, and the appearance of depressive symptoms is the most common. The main goal is determining the degree of depression with breast cancer patients in the oncology ward of the University Clinical Hospital in Niš and its connection to their marital status, age, level of education, economic status and the number of therapy cycles. This research is a prospective study. The statistical data analysis included measures of descriptive and analytical statistics. The presence of depressive symptoms of different intensity was showed in 76.00% of the interviewees in group I, and the second included 77.4%. The frequency distributions show that 27.084% interviewees from the first group showed signs of depressive symptoms, while the second included 25%. The intensity of these symptoms categorizes them into the group of moderate to significantly expressed depressive states, so they require therapeutic treatment. Depression is significantly more often recorded with cancer patients receiving cytotoxic therapy; mild depression is the most common, followed by moderate and severe depression. PMID:27138829

    Purpose: To investigate the feasibility of utilizing Dynamic Arc (DA) and IMRT with 5mm MLC leaf of VERO treatment unit for SRS/FSRT brain cancer patients with non-invasive stereotactic treatments. The DA and IMRT plans using the VERO unit (BrainLab Inc, USA) are compared with cone-based planning and proton plans to evaluate their dosimetric advantages. Methods: The Vero treatment has unique features like no rotational or translational movements of the table during treatments, Dynamic Arc/IMRT, tracking of IR markers, limitation of Ring rotation. Accuracies of the image fusions using CBCT, orthogonal x-rays, and CT are evaluated less than ∼ 0.7mm with a custom-made target phantom with 18 hidden targets. 1mm margin is given to GTV to determine PTV for planning constraints considering all the uncertainties of planning computer and mechanical uncertainties of the treatment unit. Also, double-scattering proton plans with 6F to 9F beams and typical clinical parameters, multiple isocenter plans with 6 to 21 isocenters, and DA/IMRT plans are evaluated to investigate the dosimetric advantages of the DA/IMRT for complex shape of targets. Results: 3 Groups of the patients are divided: (1) Group A (complex target shape), CI's are same for IMRT, and DGI of the proton plan are better by 9.5% than that of the IMRT, (2) Group B, CI of the DA plans (1.91+/−0.4) are better than cone-based plan, while DGI of the DA plan is 4.60+/−1.1 is better than cone-based plan (5.32+/−1.4), (3) Group C (small spherical targets), CI of the DA and cone-based plans are almost the same. Conclusion: For small spherical targets, cone-based plans are superior to other 2 plans: DS proton and DA plans. For complex or irregular plans, dynamic and IMRT plans are comparable to cone-based and proton plans for complex targets.

    Brain metastases (BM) are diagnosed in up to 40% of HER2-positive breast cancer patients. Standard treatment includes local approaches such as whole-brain radiotherapy (WBRT), radiosurgery, and neurosurgery. The landscape trial established primary systemic therapy as an effective and safe alternative to WBRT in selected patients with Her2-positive BM. We aim to further focus on the role of systemic therapy in oligosymptomatic patients by presenting this case report. We report on a 50-year-old patient diagnosed with multiple BM 5 years after early breast cancer diagnosis. As the patient was asymptomatic and had a favorable diagnosis-specific GPA score, she received primary systemic treatment with T-DM1. She achieved partial remission within the brain for eight treatment cycles and then progressed despite stable extracranial disease. As the patient remained asymptomatic and refused WBRT, we decided upon trastuzumab, lapatinib plus capecitabine as second-line therapy. Another partial remission of BM was observed; to date, she has received 11 treatment cycles without any sign of disease progression. In this case, WBRT was delayed by at least 14 months, again indicating the activity of systemic treatment in BM. Apparently, in selected patients, BM can be controlled with multiple lines of systemic therapy similar to extracranial disease. Further investigation of systemic treatment approaches is therefore warranted. PMID:25714248

    Background Breast cancer (BC) is the second most common cause of brain metastases (BM). Optimal management of BM from BC is still debated. In an attempt to provide appropriate treatment and to assist with optimal patient selection, several specific prognostic classifications for BM from BC have been established. We evaluated the prognostic value and validity of the 6 proposed scoring systems in an independent population of BC patients with BM. Methods We retrospectively reviewed all consecutive BC patients referred to our institution for newly diagnosed BM between October 1995 and July 2011 (n = 149). Each of the 6 scores proposed for BM from BC (Sperduto, Niwinska, Park, Nieder, Le Scodan, and Claude) was applied to this population. The discriminative ability of each score was assessed using the Brier score and the C-index. Individual prognostic values of clinical and histological factors were analyzed using uni- and multivariate analyses. Results Median overall survival was 15.1 months (95% CI,11.5–18.7). Sperduto-GPA (P < .001), Nieder (P < .001), Park (P < .001), Claude (P < .001), Niwinska (P < .001), and Le Scodan (P = .034) scores all showed significant prognostic value. The Nieder score showed the best discriminative ability (C-index, 0.672; Brier score error reduction, 16.1%). Conclusion The majority of prognostic scores were relevant for patients with BM from BC in our independent population, and the Nieder score seems to present the best predictive value but showed a relatively low positive predictive value. Thus, these results remain insufficient and challenge the routine use of these scoring systems. PMID:24311640

    Renal cell cancer patients with brain metastatic disease generally have poor prognosis. Treatment options include surgery, radiotherapy, targeted therapy or best supportive care with respect to disease burden, patient preference and performance status. In the present case report the radiotherapy technique combining whole brain radiotherapy with hippocampal sparing (hippocampal avoidance whole brain radiotherapy HA-WBRT) and hypofractionated stereotactic radiotherapy (SRT) of the brain metastases is performed in a patient with metastatic renal cell carcinoma. HA-WBRT was administered to 30 Gy in 10 fractions with sparing of the hippocampal structures and SRT of 21 Gy in 3 fractions to brain metastases which has preceded the HA-WBRT. Two single arc volumetric modulated arc radiotherapy (VMAT) plans were prepared using Monaco planning software. The HA-WBRT treatment plan achieved the following results: D2=33.91 Gy, D98=25.20 Gy, D100=14.18 Gy, D50=31.26 Gy. The homogeneity index was calculated as a deduction of the minimum dose in 2% and 98% of the planning target volume (PTV), divided by the minimum dose in 50% of the PTV. The maximum dose to the hippocampus was 17.50 Gy and mean dose was 11.59 Gy. The following doses to organs at risk (OAR) were achieved: Right opticus Dmax, 31.96 Gy; left opticus Dmax, 30.96 Gy; chiasma D max, 32,76 Gy. The volume of PTV for stereotactic radiotherapy was 3,736 cm3, with coverage D100=20.95 Gy and with only 0.11% of the PTV being irradiated to dose below the prescribed dose. HA-WBRT with SRT represents a feasible technique for radiotherapy of brain metastatic disease, however this technique is considerably demanding on departmental equipment and staff time/experience.

    In the last years there were many authors that suggest the existence of an association between different components of metabolic syndrome and various cancers. Two important components of metabolic syndrome are hyperglycemia and hyperinsulinemia. Both of them had already been linked with the increased risk of pancreatic, breast, endometrial or prostate cancer. However the correlation of the level of the glucose and insulin with various types and grades of brain tumors remains unclear. In this article we have analysed the values of plasma glucose and insulin in 267 patients, consecutively diagnosed with various types of brain tumors. Our results showed no correlation between the glycemia and brain tumor types or grades. High plasma levels of insulin were found in brain metastasis and astrocytomas while the other types of brain tumors (meningiomas and glioblastomas) had lower levels of the peptide. The levels of insulin were also higher in brain metastasis and grade 3 brain tumors when compared with grade 1, grade 2 and grade 4 brain tumors. PMID:24791202

    Although placebos have long been considered a nuisance in clinical research, today they represent an active and productive field of research and, because of the involvement of many mechanisms, the study of the placebo effect can actually be viewed as a melting pot of concepts and ideas for neuroscience. Indeed, there exists not a single but many placebo effects, with different mechanisms and in different systems, medical conditions, and therapeutic interventions. For example, brain mechanisms of expectation, anxiety, and reward are all involved, as well as a variety of learning phenomena, such as Pavlovian conditioning, cognitive, and social learning. There is also some experimental evidence of different genetic variants in placebo responsiveness. The most productive models to better understand the neurobiology of the placebo effect are pain and Parkinson's disease. In these medical conditions, the neural networks that are involved have been identified: that is, the opioidergic-cholecystokinergic-dopaminergic modulatory network in pain and part of the basal ganglia circuitry in Parkinson's disease. Important clinical implications emerge from these recent advances in placebo research. First, as the placebo effect is basically a psychosocial context effect, these data indicate that different social stimuli, such as words and rituals of the therapeutic act, may change the chemistry and circuitry of the patient's brain. Second, the mechanisms that are activated by placebos are the same as those activated by drugs, which suggests a cognitive/affective interference with drug action. Third, if prefrontal functioning is impaired, placebo responses are reduced or totally lacking, as occurs in dementia of the Alzheimer's type. PMID:20592717

    We investigated the diagnostic usefulness of brain magnetic resonance imaging (MRI) screening in HIV-1-infected patients without neurological symptoms in detecting intracranial diseases at early stages. In this retrospective analysis, the study patients were HIV-1-infected patients who underwent brain MRI scan in clinical practice between 2001 and 2013. We excluded patients with MRI for (1) follow-up examination for prediagnosed intracranial diseases, (2) cancer staging, (3) screening mycobacterium/bacteria/fungi disease proliferation in the brain, and (4) evaluation for meningitis/encephalitis. The study patients (n=485) were classified into two groups: those who underwent brain MRI scan without any neurological symptoms/signs (asymptomatic patients, n=158) and those who underwent MRI due to such symptoms (symptomatic patients, n=327). Asymptomatic patients had lower CD4 counts than symptomatic patients (median 78 versus 241/μl). Intracranial diseases were detected in three (2%) of the asymptomatic patients [two toxoplasmosis and one progressive multifocal leukoencephalopathy (PML)] compared to 58 (19%) of the symptomatic patients (the χ(2) test, p<0.01). The latter included toxoplasmosis (n=10), PML (n=7), cytomegalovirus encephalitis (n=3), primary central nervous system lymphoma (n=3), cryptococcoma/meningitis (n=3), and HIV-associated dementia (n=17). Among symptomatic patients, intracranial diseases were common in those with slurred speech (3/6, 50%), seizure (4/10, 40%), eyesight/vision abnormality (5/16, 31%), altered mental status (8/31, 26%), and hemiplegia/numbness (13/50, 26%). For patients with CD4 count <200/μl, intracranial diseases were detected in only 3 (3%) of 144 asymptomatic patients, compared with 46 (32%) of 113 symptomatic patients (p<0.01). Brain MRI screening for HIV-1-infected patients without neurological symptoms is of little value. PMID:25084148

    Major pulmonary disorders may occur after brain injuries as ventilator-associated pneumonia, acute respiratory distress syndrome or neurogenic pulmonary edema. They are key points for the management of brain-injured patients because respiratory failure and mechanical ventilation seem to be a risk factor for increased mortality, poor neurological outcome and longer intensive care unit or hospital length of stay. Brain and lung strongly interact via complex pathways from the brain to the lung but also from the lung to the brain. Several hypotheses have been proposed with a particular interest for the recently described “double hit” model. Ventilator setting in brain-injured patients with lung injuries has been poorly studied and intensivists are often fearful to use some parts of protective ventilation in patients with brain injury. This review aims to describe the epidemiology and pathophysiology of lung injuries in brain-injured patients, but also the impact of different modalities of mechanical ventilation on the brain in the context of acute brain injury.

    Brain metastases are common in patients with advanced breast cancer (BC), causing considerable morbidity and mortality. Eribulin is a microtubule dynamics inhibitor approved for treating certain patients with metastatic BC, previously treated with an anthracycline and a taxane. In the 301 phase 3 study in 1102 women with advanced BC, eribulin and capecitabine treatments did not differ for co-primary endpoints (overall survival [OS]: 15.9 vs 14.5 months, P = 0.056; progression-free survival [PFS]: 4.1 vs 4.2 months, P = 0.30). Here, we report outcomes for six patients (eribulin, n = 3; capecitabine, n = 3) who had received treatment for brain metastases from BC (BCBM) at baseline. All eribulin-treated patients experienced brain lesion shrinkage at some point during treatment, compared with one capecitabine-treated patient. Fewer patients in study 301 developed new BCBM with eribulin (13/544, 2.4%) compared with capecitabine (25/546, 4.6%). Eribulin does not cross the healthy blood-brain barrier (BBB), but could have the potential to do so after cranial radiation therapy. Capecitabine may cross the BBB and has demonstrated activity in BCBM. Data from these patients and previous cases suggest that further investigation of eribulin for BCBM may be warranted.

    The purpose of the study was to assess a large representative sample of cancer patients on distress levels, common psychosocial problems, and awareness and use of psychosocial support services. A total of 3095 patients were assessed over a 4-week period with the Brief Symptom Inventory-18 (BSI-18), a common problems checklist, and on awareness and use of psychosocial resources. Full data was available on 2776 patients. On average, patients were 60 years old, Caucasian (78.3%), and middle class. Approximately, half were attending for follow-up care. Types of cancer varied, with the largest groups being breast (23.5%), prostate (16.9%), colorectal (7.5%), and lung (5.8%) cancer patients. Overall, 37.8% of all patients met criteria for general distress in the clinical range. A higher proportion of men met case criteria for somatisation, and more women for depression. There were no gender differences in anxiety or overall distress severity. Minority patients were more likely to be distressed, as were those with lower income, cancers other than prostate, and those currently on active treatment. Lung, pancreatic, head and neck, Hodgkin's disease, and brain cancer patients were the most distressed. Almost half of all patients who met distress criteria had not sought professional psychosocial support nor did they intend to in the future. In conclusion, distress is very common in cancer patients across diagnoses and across the disease trajectory. Many patients who report high levels of distress are not taking advantage of available supportive resources. Barriers to such use, and factors predicting distress and use of psychosocial care, require further exploration. PMID:15162149

    The brain is one of the most common sites for non-small cell lung cancer (NSCLC) metastasis; however, late isolated brain metastasis as a recurrence of NSCLC is rare. The present study describes a case of isolated solitary brain metastasis as a late recurrence of NSCLC, which occurred >2 years following the successful resection of the primary tumor, and was identified by magnetic resonance imaging. To the best of our knowledge, this is the first report of isolated brain metastasis as a postoperative recurrence of NSCLC. The aim of the present study was to highlight that, despite its rarity, such recurrence should be considered possible, and particular attention to the treatment of such patients should be paid.

    Purpose To investigate the second primary cancers (SPCs) in patients with urothelial cancer (UC). Materials and Methods The records of 2,339 patients whose UC was diagnosed between January 1974 and December 2012 were reviewed. All data about characteristics of patients, of UC and, of SPC was, recorded digitally. We investigated the prevalence and the type of second or higher order cancers, and the factors associated with SPC. Results Total 260 patients (11.1%) had SPC, 14 had a third primary cancer and one had a fourth primary cancer. The most common SPC with UC was lung cancer (29.6%). Of all 260 with SPC, 64 (24.6%) had synchronous (within the 6 months) SPC, 120 (46.2%) had subsequent SPC and, 76 (29.2%) had antecedent SPC. The mean duration of SPC was 56 months in patients with subsequent SPC and 75.8 months in patients with antecedent SPC. The mean age at the time of diagnosis of UC was higher in patients with SPC. The ratio of male gender, body mass index, blood type, status of smoking and, occupational risk was similar in both groups. Total amount of smoking and the mean follow-up were higher in patients with SPC. Conclusions The majority of the patients with UC have long life expectancy. In patients with UC, the risk of having another cancer is quite higher than normal population. The physicians managing patients with UC should look for SPC.

  9. Targeting energy metabolism in brain cancer: review and hypothesis

    2005-01-01

    Malignant brain tumors are a significant health problem in children and adults and are often unmanageable. As a metabolic disorder involving the dysregulation of glycolysis and respiration, malignant brain cancer is potentially manageable through changes in metabolic environment. A radically different approach to brain cancer management is proposed that combines metabolic control analysis with the evolutionarily conserved capacity of normal cells to survive extreme shifts in physiological environment. In contrast to malignant brain tumors that are largely dependent on glycolysis for energy, normal neurons and glia readily transition to ketone bodies (β-hydroxybutyrate) for energy in vivo when glucose levels are reduced. The bioenergetic transition from glucose to ketone bodies metabolically targets brain tumors through integrated anti-inflammatory, anti-angiogenic, and pro-apoptotic mechanisms. The approach focuses more on the genomic flexibility of normal cells than on the genomic defects of tumor cells and is supported from recent studies in orthotopic mouse brain tumor models and in human pediatric astrocytoma treated with dietary energy restriction and the ketogenic diet.

    The median survival time of breast cancer patients with brain metastasis is less than 6 months, and even a small metastatic lesion often causes severe neurological disabilities. Because of the location of metastatic lesions, a surgical approach is limited and most chemotherapeutic drugs are ineffective due to the blood brain barrier (BBB). Despite this clinical importance, the molecular basis of the brain metastasis is poorly understood. In this study, we have isolated RNA from samples obtained from primary breast tumors and also from brain metastatic lesions followed by microRNA profiling analysis. Our results revealed that the miR-509 is highly expressed in the primary tumors, while the expression of this microRNA is significantly decreased in the brain metastatic lesions. MicroRNA target prediction and the analysis of cytokine array for the cells ectopically expressed with miR-509 demonstrated that this microRNA was capable of modulating two genes essential for brain invasion, RhoC and TNFα that affect the invasion of cancer cells and permeability of BBB, respectively. Importantly, high levels of TNFα and RhoC-induced MMP9 were significantly correlated with brain metastasis-free survival of breast cancer patients. Furthermore, the results of our in vivo experiments indicate that miR-509 significantly suppressed the ability of cancer cells to metastasize to the brain. These findings suggest that miR-509 plays a critical role in brain metastasis of breast cancer by modulating the RhoC-TNFα network and that this miR-509 axis may represent a potential therapeutic target or serve as a prognostic tool for brain metastasis.

    2013-01-01

    Background To develop a Consumer Quality Index (CQI) Cancer Care questionnaire for measuring experiences with hospital care of patients with different types of cancer. Methods We derived quality aspects from focus group discussions, existing questionnaires and literature. We developed an experience questionnaire and sent it to 1,498 Dutch cancer patients. Another questionnaire measuring the importance of the quality aspects was sent to 600 cancer patients. Data were psychometrically analysed. Results The response to the experience questionnaire was 50 percent. Psychometric analysis revealed 12 reliable scales. Patients rated rapid and adequate referral, rapid start of the treatment after diagnosis, enough information and confidence in the healthcare professionals as most important themes. Hospitals received high scores for skills and cooperation of healthcare professionals and a patient-centered approach by doctors; and low scores for psychosocial guidance and information at completion of the treatment. Conclusions The CQI Cancer Care questionnaire is a valuable tool for the evaluation of the quality of cancer care from the patient’s perspective. Large scale implementation is necessary to determine the discriminatory powers of the questionnaire and may enable healthcare providers to improve the quality of cancer care. Preliminary results indicate that hospitals could improve their psychosocial guidance and information provision. PMID:23617741

    A complete understanding of the biological mechanisms regulating devastating disease such as cancer remains elusive. Pancreatic and brain cancers are primary among the cancer types with poor prognosis. Molecular biomarkers have emerged as group of proteins that are preferentially overexpressed in cancers and with a key role in driving disease progression and resistance to chemotherapy. The epidermal growth factor receptor (EGFR), a cell proliferative biomarker is particularly highly expressed in most cancers including brain and pancreatic cancers. The ability of EGFR to sustain prolong cell proliferation is augmented by biomarkers such as Bax, Bcl-XL and Bcl-2, proteins regulating the apoptotic process. To better understand the role and effect of the microenvironment on these biomarkers in pancreatic cancer (PaCa); we analysed two pancreatic tumor lines (AsPc-1 and MiaPaCa-2) in 2D, 3D in-vitro cultures and in orthotopic tumors at different growth stages. We also investigated in patient derived glioblastoma (GBM) tumor cultures, the ability to utilize the EGFR expression to specifically deliver photosensitizer to the cells for photodynamic therapy. Overall, our results suggest that (1) microenvironment changes affect biomarker expression; thereby it is critical to understand these effects prior to designing combination therapies and (2) EGFR expression in tumor cells indeed could serve as a reliable and a robust biomarker that could be used to design targeted and image-guided photodynamic therapy.

    Brain abscesses caused by Nocardia are rare but have a very high mortality and specific requirements of antibiotic treatment. Nocardial brain abscesses are mainly found in patients with predisposing conditions such as pulmonary alveolar proteinosis (PAP), a disease associated with chronic exposure to silica dust. We present a case of multiple nocardial brain abscesses in a man with PAP probably due to long-term occupational exposure to silica dust. Conclusively, in patients presenting brain abscesses and a history of chronic exposure to silica dust, PAP and opportunistic nocardial infection should always be considered as possible diagnoses.

    At various stage of progression, most brain tumors are not homogenous. In this presentation, we retrospectively studied the distribution of ADC values inside tumor volume during the course of tumor treatment and progression for a selective group of patients who underwent an anti-VEGF trial. Complete MRI studies were obtained for this selected group of patients including pre- and multiple follow-up, post-treatment imaging studies. In each MRI imaging study, multiple scan series were obtained as a standard protocol which includes T1, T2, T1-post contrast, FLAIR and DTI derived images (ADC, FA etc.) for each visit. All scan series (T1, T2, FLAIR, post-contrast T1) were registered to the corresponding DTI scan at patient's first visit. Conventionally, hyper-intensity regions on T1-post contrast images are believed to represent the core tumor region while regions highlighted by FLAIR may overestimate tumor size. Thus we annotated tumor regions on the T1-post contrast scans and ADC intensity values for pixels were extracted inside tumor regions as defined on T1-post scans. We fit a mixture Gaussian (MG) model for the extracted pixels using the Expectation-Maximization (EM) algorithm, which produced a set of parameters (mean, various and mixture coefficients) for the MG model. This procedure was performed for each visits resulting in a series of GM parameters. We studied the parameters fitted for ADC and see if they can be used as indicators for tumor progression. Additionally, we studied the ADC characteristics in the peri-tumoral region as identified by hyper-intensity on FLAIR scans. The results show that ADC histogram analysis of the tumor region supports the two compartment model that suggests the low ADC value subregion corresponding to densely packed cancer cell while the higher ADC value region corresponding to a mixture of viable and necrotic cells with superimposed edema. Careful studies of the composition and relative volume of the two compartments in tumor

    Purpose Brain metastases of breast cancer cause neurocognitive damage and are incurable. We evaluated a role for temozolomide in the prevention of brain metastases of breast cancer in experimental brain metastasis models. Experimental Design Temozolomide was administered in mice following earlier injection of brain-tropic human epidermal growth factor receptor 2 (HER2)-positive Jimt1-BR3 and triple negative 231-BR-EGFP sublines, the latter with and without expression of 06-methylguanine-DNA methyltransferase (MGMT). Additionally, the percentage of MGMT-positive tumor cells in 62 patient-matched sets of breast cancer primary tumors and resected brain metastases was determined immunohistochemically. Results Temozolomide, when dosed at 50, 25, 10 or 5 mg/kg, 5 days/week, beginning 3 days after inoculation, completely prevented the formation of experimental brain metastases from MGMT-negative 231-BR-EGFP cells. At a 1 mg/kg dose, temozolomide prevented 68% of large brain metastases, and was ineffective at a dose of 0.5 mg/kg. When the 50 mg/kg dose was administered beginning on days 18 or 24, temozolomide efficacy was reduced or absent. Temozolomide was ineffective at preventing brain metastases in MGMT-transduced 231-BR-EGFP and MGMT-expressing Jimt-1-BR3 sublines. In 62 patient-matched sets of primary breast tumors and resected brain metastases, 43.5% of the specimens had concordant low MGMT expression, while in another 14.5% of sets high MGMT staining in the primary tumor corresponded with low staining in the brain metastasis. Conclusions Temozolomide profoundly prevented the outgrowth of experimental brain metastases of breast cancer in an MGMT-dependent manner. These data provide compelling rationale for investigating the preventive efficacy of temozolomide in a clinical setting. PMID:24634373

    Brain metastases are commonly found in patients that are diagnosed with primary malignancy on their lung. Lung cancer patients with brain metastasis tend to have a poor survivability, which is less than 6 months in median. Therefore, an early and effective detection system for such disease is needed to help prolong the patients' survivability and improved their quality of life. A modified electromagnetism-like mechanism (EM) algorithm, MEM-SVM, is proposed by combining EM algorithm with support vector machine (SVM) as the classifier and opposite sign test (OST) as the local search technique. The proposed method is applied to 44 UCI and IDA datasets, and 5 cancers microarray datasets as preliminary experiment. In addition, this method is tested on 4 lung cancer microarray public dataset. Further, we tested our method on a nationwide dataset of brain metastasis from lung cancer (BMLC) in Taiwan. Since the nature of real medical dataset to be highly imbalanced, the synthetic minority over-sampling technique (SMOTE) is utilized to handle this problem. The proposed method is compared against another 8 popular benchmark classifiers and feature selection methods. The performance evaluation is based on the accuracy and Kappa index. For the 44 UCI and IDA datasets and 5 cancer microarray datasets, a non-parametric statistical test confirmed that MEM-SVM outperformed the other methods. For the 4 lung cancer public microarray datasets, MEM-SVM still achieved the highest mean value for accuracy and Kappa index. Due to the imbalanced property on the real case of BMLC dataset, all methods achieve good accuracy without significance difference among the methods. However, on the balanced BMLC dataset, MEM-SVM appears to be the best method with higher accuracy and Kappa index. We successfully developed MEM-SVM to predict the occurrence of brain metastasis from lung cancer with the combination of SMOTE technique to handle the class imbalance properties. The results confirmed that MEM

    We report a case of a 52-year-old Caucasian man with invasive ductal carcinoma of the breast. One year after initial diagnosis, he developed a generalised epileptic seizure and neuroimaging showed multiple, calcified intracerebral lesions. Owing to these atypical cerebral imaging findings, comprehensive serological and cerebrospinal fluid analysis was conducted and a latent toxoplasmosis was suspected. In order to distinguish between metastases and an infectious disease, a cerebral biopsy was performed, which verified brain metastases. The patient received whole-brain radiotherapy. The last cerebral CT scan, 18 months later showed stable disease. Calcification of brain metastases in patients with breast cancer is very rare. Owing to their non-characteristic radiological appearance with a lack of contrast enhancement, diagnosis of metastases can be difficult. Infectious diseases should be considered within the diagnostic work up. Owing to possible pitfalls, we recommend a widespread differential diagnostic work up in similar cases, and even in cases with a confirmed primary tumour. PMID:26472289

    Treatment of glioblastoma multiforme (GBM) and brain metastasis remains a challenge because of the poor survival and the potential for brain damage following radiation. Despite concurrent chemotherapy and radiation dose escalation, local recurrence remains the predominant pattern of failure in GBM most likely secondary to repopulation of cancer stem cells. Even though radiotherapy is highly effective for local control of radio-resistant tumors such as melanoma and renal cell cancer, systemic disease progression is the cause of death in most patients with brain metastasis. Preservation of quality of life (QOL) of cancer survivors is the main issue for patients with brain metastasis. Image-guided radiotherapy (IGRT) by virtue of precise radiation dose delivery may reduce treatment time of patients with GBM without excessive toxicity and potentially improve neurocognitive function with preservation of local control in patients with brain metastasis. Future prospective trials for primary brain tumors or brain metastasis should include IGRT to assess its efficacy to improve patient QOL. PMID:24312897

    Formation of metastases from various tumor entities in the brain is a major problem for the treatment of advanced cancer. We describe target molecules and tools for the delivery of small molecules or proteins across the blood-brain barrier (BBB), and the treatment of brain tumors and metastases with antibody-related moieties. In addition, drugs preventing formation of metastases or interfering with the growth of established metastases are described, as well as pre-clinical metastasis models and corresponding clinical data. Furthermore, we discuss the delivery of effector proteins and antibody-based moieties fused with an antibody-based scaffold across the BBB in several model systems which might be applicable for the treatment of brain metastases.

    Brain metastases are associated with high morbidity as well as with poor prognosis and survival in breast cancer patients. Despite its clinical importance, metastasis of breast cancer cells through the blood-brain barrier (BBB) is poorly understood. The objective of our study was to investigate whether cancer-associated fibroblasts (CAFs) play crucial roles in breast cancer brain metastasis. Using a cell adhesion assays, in vitro BBB permeability and transmigration assays and soft agar colony formation assays, we investigated the physical roles of CAFs in breast cancer brain metastasis. We also performed immunofluorescence, flow cytometric analysis, Droplet Digital PCR and Simon™ Simple Western System to confirm changes in expression levels. We established two novel three-dimensional (3D) culture systems using a perpendicular slide chamber and applying 3D embedded culture method to reflect brain metastasis conditions. With a newly developed device, CAFs was proven to promote cell adhesion to human brain microvascular endothelial cells, in vitro BBB permeability and transmigration and colony formation of breast cancer cells. Furthermore, CAFs enhanced the invasive migration of breast cancer cells in two kinds of 3D cultures. These 3D models also reliably recapitulate the initial steps of BBB transmigration, micro-metastasis and colonization. Expression of integrin α5β1 and αvβ3, c-MET and α2,6-siayltransferase was increased in breast cancer cells that migrated through the BBB. In conclusion, based on our in vitro BBB and co-culture models, our data suggest that CAFs may play a role in breast cancer brain metastasis. PMID:24643985

    Neurospecific proteins S-100 and GFAP were measured in the serum of 145 patients with neural tumors and 69 healthy individuals. In patients with glyoblastomas, the concentrations of S-100 and GFAP were significantly higher than in patients with anaplastic astrocytomas, benign meningiomas, and brain metastases and in healthy individuals. Serum S-100 concentrations in patients with anaplastic astrocytomas, benign meningiomas, and brain metastases were similar; significant difference from the control was found only for patients with cerebral metastases. A specific feature of GFAP was high incidence of its detection in patients with glioblastomas (83%) compared to other groups of patients with neural tumors and healthy volunteers who demonstrated practically zero level of this protein. These findings attest to the possibility of using S-100 as an additional biochemical criterion of brain involvement in tumor patients and GFAP as a glioblastoma marker. PMID:22235430

    A monoclonal antibody was prepared against pooled homogenates of brain tissue from patients with Alzheimer's disease. This antibody recognizes an antigen present in much higher concentration in certain brain regions of Alzheimer patients than in normal brain. The antigen appears to be a protein present in neurons involved in the formation of neuritic plaques and neurofibrillary tangles, and in some morphologically normal neurons in sections from Alzheimer brains. Partial purification and Western blot analysis revealed the antigen from Alzheimer brain to be a single protein with a molecular weight of 68,000. Application of the same purification procedure to normal brain tissue results in the detection of small amounts of a protein of lower molecular weight. PMID:3083509

    Neurocognitive impairment is being increasingly recognized as an important issue in patients with cancer who develop cognitive difficulties either as part of direct or indirect involvement of the nervous system or as a consequence of either chemotherapy-related or radiotherapy-related complications. Brain radiotherapy in particular can lead to significant cognitive defects. Neurocognitive decline adversely affects quality of life, meaningful employment, and even simple daily activities. Neuroprotection may be a viable and realistic goal in preventing neurocognitive sequelae in these patients, especially in the setting of cranial irradiation. Lithium is an agent that has been in use for psychiatric disorders for decades, but recently there has been emerging evidence that it can have a neuroprotective effect.This review discusses neurocognitive impairment in patients with cancer and the potential for investigating the use of lithium as a neuroprotectant in such patients.

    Purpose: Erlotinib has shown activity in patients with brain metastases from non-small-cell lung cancer. The present dose-escalation Phase I trial evaluated the toxicity of whole brain radiotherapy (WBRT) with concurrent and maintenance erlotinib in this patient group. Methods and Materials: Erlotinib (Cohort 1, 100 mg/d; Cohort 2, 150 mg/d) was started 1 week before, and continued during, WBRT (30 Gy in 10 fractions). Maintenance erlotinib (150 mg/d) was continued until unacceptable toxicity or disease progression. Results: A total of 11 patients completed WBRT, 4 in Cohort 1 and 7 in Cohort 2. The median duration of erlotinib treatment was 83 days. No treatment-related neurotoxicity was observed. No treatment-related Grade 3 or greater toxicity occurred in Cohort 1. In Cohort 2, 1 patient developed a Grade 3 acneiform rash and 1 patient had Grade 3 fatigue. Two patients in Cohort 2 developed erlotinib-related interstitial lung disease, contributing to death during maintenance therapy. The median overall survival and interval to progression was 133 and 141 days, respectively. Six patients developed extracranial progression; only 1 patient had intracranial progression. In 7 patients with follow-up neuroimaging at 3 months, 5 had a partial response and 2 had stable disease. Conclusion: WBRT with concurrent erlotinib is well tolerated in patients with brain metastases from non-small-cell lung cancer. The suggestion of a high intracranial disease control rate warrants additional study.

    Purpose: To evaluate prognostic factors for survival after stereotactic radiosurgery (SRS) for new, progressive, or recurrent brain metastases (BM) after prior whole brain radiotherapy (WBRT). Methods and Materials: Patients treated between 1991 and 2007 with Gamma Knife SRS for BM after prior WBRT were retrospectively reviewed. Potential prognostic factors were analyzed overall and by primary site using univariate and stepwise multivariate analyses and recursive partitioning analysis, including age, Karnofsky performance status (KPS), primary tumor control, extracranial metastases, number of BM treated, total SRS target volume, and interval from WBRT to SRS. Results: A total of 310 patients were analyzed, including 90 breast, 113 non-small-cell lung, 31 small-cell lung, 42 melanoma, and 34 miscellaneous patients. The median age was 56, KPS 80, number of BM treated 3, and interval from WBRT to SRS 8.1 months; 76% had controlled primary tumor and 60% had extracranial metastases. The median survival was 8.4 months overall and 12.0 vs. 7.9 months for single vs. multiple BM treated (p = 0.001). There was no relationship between number of BM and survival after excluding single-BM patients. On multivariate analysis, favorable prognostic factors included age <50, smaller total target volume, and longer interval from WBRT to SRS in breast cancer patients; smaller number of BM, KPS >60, and controlled primary in non-small-cell lung cancer patients; and smaller total target volume in melanoma patients. Conclusions: Among patients treated with salvage SRS for BM after prior WBRT, prognostic factors appeared to vary by primary site. Although survival time was significantly longer for patients with a single BM, the median survival time of 7.9 months for patients with multiple BM seems sufficiently long for salvage SRS to appear to be worthwhile, and no evidence was found to support the use of a cutoff for number of BM appropriate for salvage SRS.

    Toxic epidermal necrolysis (TEN) is a severe drug induced type IV hypersensitivity syndrome that can be caused by anticonvulsant drugs, especially the aromatic anticonvulsants such as phenytoin. Most patients with brain metastasis receive whole brain radiotherapy along with anti-edema measures and anticonvulsants either as prophylactic or for symptom control; phenytoin being the most commonly used drug. In a subset of patients, cranial irradiation may act as a precipitating factor along with anticonvulsants for the development of TEN. We report a 54-year-old patient with metastatic non-small cell lung cancer treated with palliative whole brain and mediastinal radiotherapy with concurrent phenytoin-developing TEN, which started within the radiation portals with subsequent generalization. Though a rare, but serious complication, avoidance of the use of phenytoin concurrent with radiotherapy, replacing phenytoin with newer anticonvulsants, early recognition, aggressive management and awareness of this possible complication has been implied upon in this report.

    Change in cell stiffness is a new characteristic of cancer cells that affects the way they spread. Despite several studies on architectural changes in cultured cell lines, no ex vivo mechanical analyses of cancer cells obtained from patients have been reported. Using atomic force microscopy, we report the stiffness of live metastatic cancer cells taken from the body (pleural) fluids of patients with suspected lung, breast and pancreas cancer. Within the same sample, we find that the cell stiffness of metastatic cancer cells is more than 70% softer, with a standard deviation over five times narrower, than the benign cells that line the body cavity. Different cancer types were found to display a common stiffness. Our work shows that mechanical analysis can distinguish cancerous cells from normal ones even when they show similar shapes. These results show that nanomechanical analysis correlates well with immunohistochemical testing currently used for detecting cancer.

    Volume measurements were carried out on 19 brains from leucotomised schizophrenic patients and 20 age- and sex-matched controls using a stereological method. The volume of the total fixed brain, hemispheres, cortex, white matter, and central grey matter were all significantly reduced compared with controls. White matter and central grey structures were significantly reduced compared with a group of non-leucotomised schizophrenic brains. No difference was found in the size of the lesions in patients who improved compared with the patients who remained unchanged and the outcome was unrelated to lesional asymmetry. Morphometric measurements were correlated to a number of clinical parameters. PMID:2703834

    Special consideration is required when prescribing antipsychotic drugs for patients with an existing diagnosis of breast cancer. The package inserts of all approved antipsychotics contain precautions regarding their administration in this patient group. These drugs are well known to elevate serum prolactin levels to varying degrees. Overexpression of the prolactin receptor is seen in more than 95% of human breast cancers. Many genes that are activated by the prolactin receptor are associated with tumorigenesis and cancer cell proliferation. The authors discuss the pathophysiology, clinical implications, and pertinent preclinical data and make specific recommendations regarding the use of antipsychotics in patients with breast cancer.

    Gliomas are some of the most aggressive types of cancers but the blood-brain barrier acts as an obstacle to therapeutic intervention in brain-related diseases. The blood-brain barrier blocks the permeation of potentially toxic compounds into neural tissue through the interactions of brain endothelial cells with glial cells (astrocytes and pericytes) which induce the formation of tight junctions in endothelial cells lining the blood capillaries. In the present study, we characterize a glutathione-coated docetaxel-loaded PEG-PLGA nanoparticle, show its in vitro drug release data along with cytotoxicity data in C6 and RG2 cells, and investigate its trans-blood-brain barrier permeation through the establishment of a Transwell cellular co-culture. We show that the docetaxel-loaded nanoparticle's size enables its trans-blood-brain barrier permeation; the nanoparticle exhibits a steady, sustained release of docetaxel; the drug is able to induce cell death in glioma models; and the glutathione-coated nanoparticle is able to permeate through the Transwell in vitro blood-brain barrier model.

    Cerebral metastases are the most common brain neoplasms seen clinically in the adults and comprise more than half of all brain tumours. Actual treatment options for brain metastases that include surgical resection, radiotherapy and chemotherapy are rarely curative, although palliative treatment improves survival and life quality of patients carrying brain-metastatic tumours. Chemotherapy in particular has also shown limited or no activity in brain metastasis of most tumour types. Many chemotherapeutic agents used systemically do not cross the blood-brain barrier (BBB), whereas others may transiently weaken the BBB and allow extravasation of tumour cells from the circulation into the brain parenchyma. Increasing evidence points out that the interaction between the BBB and tumour cells plays a key role for implantation and growth of brain metastases in the central nervous system. The BBB, as the tightest endothelial barrier, prevents both early detection and treatment by creating a privileged microenvironment. Therefore, as observed in several in vivo studies, precise targetting the BBB by a specific transient opening of the structure making it permeable for therapeutic compounds, might potentially help to overcome this difficult clinical problem. Moreover, a better understanding of the molecular features of the BBB, its interrelation with metastatic tumour cells and the elucidation of cellular mechanisms responsible for establishing cerebral metastasis must be clearly outlined in order to promote treatment modalities that particularly involve chemotherapy. This in turn would substantially expand the survival and quality of life of patients with brain metastasis, and potentially increase the remission rate. Therefore, the focus of this review is to summarise the current knowledge on the role and function of the BBB in cancer metastasis. PMID:26032862

    Brain metastases (BM) from breast cancer are associated with high morbidity and a poor prognosis. The aim of this study was to analyse the role of radiotherapy in treatment of BM from breast cancer in the context of modern local therapy modalities, current systemic treatment options and prognostic factors. A retrospective analysis of 86 consecutive female patients treated with radiotherapy for BM from breast cancer between 2000 and 2010 was conducted. Patient and treatment characteristics were registered and survival data calculated. All patients received whole-brain radiotherapy (WBRT) with a median dose of 36 Gy, and 19 patients were treated with an additional boost; this included fractionated schemes (median dose, 18 Gy) and radiosurgery (5 and 17 Gy). The median overall survival time from the start of WBRT was 4.1 months in the present cohort. Patients receiving a boost survived 19.7 months in comparison to 3.1 months for patients treated with WBRT alone (P<0.001). Other factors that improved overall survival, based on a univariate analysis, were dose of WBRT and number of BM. There was no statistical evidence for the influence of the human epidermal growth factor receptor 2 status on survival in the current study. The administration of boost treatment following WBRT was also identified as a significant factor influencing survival on multivariate analysis (P=0.030). In conclusion, radiotherapy affects the survival time of patients with BM from breast cancer. In particular, the implementation of boost treatment following WBRT in selected patients seems to extend survival time. PMID:27123095

    Medical imaging systems often produce images that require enhancement, such as improving the image contrast as they are poor in contrast. Therefore, they must be enhanced before they are examined by medical professionals. This is necessary for proper diagnosis and subsequent treatment. We do have various enhancement algorithms which enhance the medical images to different extents. We also have various quantitative metrics or measures which evaluate the quality of an image. This paper suggests the most appropriate measures for two of the medical images, namely, brain cancer images and breast cancer images. PMID:27127497

    The knowledge of human brain temperature is still very limited. In this report we investigated the relationship between brain and trunk temperature in neurosurgical patients during normothermia and fever. Another problem addressed was that of possible gradients of temperature within the brain. We carried out direct recordings of temperature in 63 operated, neurosurgical patients with a variety of intracranial pathologies. Flexible, teflon-coated thermocouples were placed intracranially during neurosurgical procedures. Oesophageal, rectal and tympanic temperatures were also monitored. An error of up to 1.3 degrees C is to be expected in single cases if brain temperature is deduced from the rectal or oesophageal temperature. Mean differences between brain temperature and core body temperature measured in the rectum or in the oesophagus, were between 0 to 0.3 degree C. Tympanic temperature (Tty) improved the approximation of brain temperature (Tbr) to within the mean difference between Tbr-Tty close to 0 degree C. Nevertheless Tty also differed from Tbr by as much as 1 degree C in single cases. Brain temperature was the highest body temperature measured, either in normothermia or in fever. Temperature gradients were proved to exist between the warmer brain interior and cooler surface, with maximal differences in temperature reaching 0.6 degree C. This temperature gradient tended to increase along with the rise in intracranial pressure and deterioration of the level of consciousness. Our results suggest that conclusions regarding brain temperature drawn on the basis of other core temperatures, may lead to significant errors, and intracranial temperature measurement is desirable in neurosurgical intensive care. Temperature gradients within the brain may exacerbate its biochemical injury during ischaemia and fever--a combination seen frequently in neurosurgical patients. This may be particularly so, since brain temperature in fever is the highest body temperature in a

    Venous thromboembolism occurs frequently in patients with cancer who have brain metastases, but there is limited evidence supporting the safety of therapeutic anticoagulation. To assess the risk for intracranial hemorrhage associated with the administration of therapeutic doses of low-molecular-weight heparin, we performed a matched, retrospective cohort study of 293 patients with cancer with brain metastases (104 with therapeutic enoxaparin and 189 controls). A blinded review of radiographic imaging was performed, and intracranial hemorrhages were categorized as trace, measurable, and significant. There were no differences observed in the cumulative incidence of intracranial hemorrhage at 1 year in the enoxaparin and control cohorts for measurable (19% vs 21%; Gray test, P = .97; hazard ratio, 1.02; 90% confidence interval [CI], 0.66-1.59), significant (21% vs 22%; P = .87), and total (44% vs 37%; P = .13) intracranial hemorrhages. The risk for intracranial hemorrhage was fourfold higher (adjusted hazard ratio, 3.98; 90% CI, 2.41-6.57; P < .001) in patients with melanoma or renal cell carcinoma (N = 60) than lung cancer (N = 153), but the risk was not influenced by the administration of enoxaparin. Overall survival was similar for the enoxaparin and control cohorts (8.4 vs 9.7 months; Log-rank, P = .65). We conclude that intracranial hemorrhage is frequently observed in patients with brain metastases, but that therapeutic anticoagulation does not increase the risk for intracranial hemorrhage.

    Brain tumor heterogeneity remains a challenge for probing brain cancer evolutionary dynamics. In light of evolution, it is a priority to inspect the cancer system from a time-domain perspective since it explicitly tracks the dynamics of cancer variations. In this paper, we study the problem of exploring brain tumor heterogeneity from temporal clinical magnetic resonance imaging (MRI) data. Our goal is to discover evidence-based knowledge from such temporal imaging data, where multiple clinical MRI scans from Glioblastoma multiforme (GBM) patients are generated during therapy. In particular, we propose a quantitative histogram-based approach that builds a prediction model to measure the difference in histograms obtained from pre- and post-treatment. The study could significantly assist radiologists by providing a metric to identify distinctive patterns within each tumor, which is crucial for the goal of providing patient-specific treatments. We examine the proposed approach for a practical application - clinical survival group prediction. Experimental results show that our approach achieved 90.91% accuracy.

    Alexandra Dane Dor-Ner ("Ali" to friends) was a photographer, writer, and a producer of programs on child development. In February 1989, at the age of 41, she was diagnosed with malignant brain cancer. During the following months she underwent brain surgery, radiation, and implant radiation. Throughout her treatment, she continued to work on a novel and write stores and literary criticism. A volunteer in hospitals before her illness, she now became very active in a support group of brain tumor patients and often served as a first resource and contact for others diagnosed with brain cancer. All was very accomplished; her award-winning photographs have been exhibited in the Smithsonian Institution in Washington, and her articles and pictures were published in books, periodicals, and newspapers around the world. A native of Boston, Ali lived for 17 years in Israel, where she joined a group of photographers documenting disappearing neighborhoods in Jerusalem. She was awarded first prize in the "Israel Through the Camera's Eye" competition in 1977. She also taught English and photography in Israeli high schools. Ali traveled extensively on photographic assignments. Early in their 22-year marriage, she and her husband circumnavigated the globe on a freighter, producing a documentary film of the voyage. "Memoirs of an Amnesiac" was written while Ali was a student at the Warren Wilson College Writers' Program in North Carolina; she intended to explore the compensatory aspects of her disease. In February 1991, within days of completing the piece, Ali had a third brain operation to remove a regrowth of cancerous tumor cells, as well as necrotic tissue. Two days later, she was again operated on to remove blood clots resulting from the previous surgery. For the next 12 weeks she fought to regain her ability to walk, talk, and write. In May, she underwent a fifth operation to relieve pressure in the brain. She was still in the hospital when she learned, to her great pleasure

    The current concepts, recommendations, and principles of sperm banking as it pertains to the comprehensive care of young men of reproductive age with cancer are reviewed. Obstacles to sperm banking are addressed as well as future directions for fertility-preserving technologies. All cancer therapies—chemotherapy, radiation, and surgery—are potential threats to a man’s reproductive potential. In addition, cancer itself can impair spermatogenesis. Thus, sperm cryopreservation prior to initiating life-saving cancer treatment offers men and their families the best chance to father biologically related children and should be offered to all men with cancer before treatment. Better patient and provider education, as well as deliberate, coordinated strategies at comprehensive cancer care centers are necessary to make fertility preservation for male cancer patients a priority during pretreatment planning.

Following were more depressed in CR patients: mean corpuscular hemoglobin-MCH & lymphocytes-LYM, hematocrit, mean corpuscular hemoglobin concentration-MCHC, hemoglobin-HB and red blood cells-RBC. In RT patients, following were more depressed: LYM, MCH and MCHC. Overall, in all cancer patients, the lymphocytes were depressed 52%. There existed a significant difference between white blood cells and RBC in both CR and RT patients. A significant moderate negative correlation is found in HB with the dose range 30-78 (Gray) given to the CR cancer patients. More number of CBC parameters affected in patients treated with CR and RT; but in less percentage as compared to patients who treated with RT alone. The cancer patients suffered from anemia along with immune modulations from the treatments. PMID:27423975

    This letter to the editor describes the case of a 42 year old man with mild traumatic brain injury and multiple neuropsychiatric symptoms which persisted for a few years after the injury. Initial CT scans and MRI scans of the brain showed no signs of atrophy. Brain volume was measured using NeuroQuant®, an FDA-approved, commercially available software method. Volumetric cross-sectional (one point in time) analysis also showed no atrophy. However, volumetric longitudinal (two points in time) analysis showed progressive atrophy in several brain regions. This case illustrated in a single patient the principle discovered in multiple previous group studies, namely that the longitudinal design is more powerful than the cross-sectional design for finding atrophy in patients with traumatic brain injury.

    Islamic healing is frequently referred to as the treatment of choice by many Muslim cancer patients in Malaysia. Despite its widespread use, there is limited information relating to patients' healing preferences. With rising cancer rates in the country, this issue has become a concern to public health policy makers. The purpose of this study was to understand why cancer patients seek Islamic healing. This qualitative study utilized in-depth interviews with 18 cancer patients. The findings indicate three main reasons: (1) recommendations from family, friends and doctors; (2) belief in Islamic healing and (3) the perceived ineffectiveness and dissatisfaction with conventional treatments. Islamic healing will likely continue to be popular complementary cancer treatment in Malaysia as it is grounded in strong cultural and religious beliefs. PMID:26391242

    The goal of this review is to discuss the psychiatric aspects of pain in cancer patients from a biopsychosocial approach. Pain in cancer patients is considered as a complex reaction causing severe suffering and involves many psychological aspects. It has many dimensions such as personality, affect, cognition and social relations. The pain experience may also be influenced by some psychological factors such as anxiety, depression and the meaning of pain. Therefore, a successful management of cancer pain requires a multidisciplinary approach. Since cancer pain is generally treated medically, the psychological impact of pain is often underestimated. However, cancer pain is usually related to high levels of psychological distress. Culture, as an important factor affecting cancer pain, will also be discussed during this review. It is crucial to understand cultural diversity in the treatment of cancer patients with pain. Research shows that a minority patients of various ethnicities have less control of their pain because of the miscommunication problem within the medical setting. By paying attention to patients' cultural diversities, problems such as miscommunication causing inadequate control of pain can be eliminated. In order to manage pain in cancer patients, cognitive-behavioral interventions may be integrated with pharmacotherapy. The main goal of these strategies is to provide a sense of control and better coping skills to deal with cancer. Patients' maladaptive thoughts or behaviors may cause physical and emotional stress. Main behavioral strategies include biofeedback, relaxation training, and hypnosis. Cognitive strategies include guided imagery, distraction, thought monitoring and problem solving. By discussing all of these aspects of cancer pain, the multidimensional characteristic of pain and the relation between cancer pain and psychiatric factors will be clarified. PMID:20590361

    Brain injury is frequently observed after sepsis and may be primarily related to the direct effects of the septic insult on the brain (e.g., brain edema, ischemia, seizures) or to secondary/indirect injuries (e.g., hypotension, hypoxemia, hypocapnia, hyperglycemia). Management of brain injury in septic patients is first focused to exclude structural intracranial complications (e.g., ischemic/hemorrhagic stroke) and possible confounders (e.g., electrolyte alterations or metabolic disorders, such as dysglycemia). Sepsis-associated brain dysfunction is frequently a heterogeneous syndrome. Despite increasing understanding of main pathophysiologic determinants, therapy is essentially limited to protect the brain against further cerebral damage, by way of "simple" therapeutic manipulations of cerebral perfusion and oxygenation and by avoiding over-sedation. Non-invasive monitoring of cerebral perfusion and oxygenation with transcranial Doppler (TCD) and near-infrared spectroscopy (NIRS) is feasible in septic patients. Electroencephalography (EEG) allows detection of sepsis-related seizures and holds promise also as sedation monitoring. Brain CT-scan detects intra-cerebral structural lesions, while magnetic resonance imaging (MRI) provides important insights into primary mechanisms of sepsis-related direct brain injury, (e.g., cytotoxic vs. vasogenic edema) and the development of posterior reversible encephalopathy. Together with EEG and evoked potentials (EP), MRI is also important for coma prognostication. Emerging clinical evidence suggests monitoring of the brain in septic patients can be implemented in the ICU. The objective of this review was to summarize recent clinical data about the role of brain monitoring - including TCD, NIRS, EEG, EP, CT, and MRI - in patients with sepsis and to illustrate its potential utility for the diagnosis, management and prognostication.

    Endogenous opioid peptides have been shown to be involved in the regulation of tumour growth. At present, however, no data are available about the secretion of opioid peptides in cancer patients. To draw some preliminary conclusions on opioid brain function in human neoplasms, we evaluated hypophyseal hormone responses to the administration of a met-enkephalin analogue, FK 33-824. The study included 14 patients affected by early or advanced neoplastic disease, 12 healthy subjects and 7 patients with a chronic medical illness other than cancer. FK 33-824 was given intravenously at a dose of 0.3 mg. Venous blood samples were collected at zero time, and 30, 60 and 120 min after drug administration. In each sample, PRL, GH, LH, cortisol and beta-endorphin levels were measured by RIA. In all normal subjects and in patients with non-neoplastic chronic illness, FK 33-824 induced a rise in PRL and GH levels, and a decrease in LH, cortisol and beta-endorphin. A normal endocrine response to FK 33-824 was seen in our cancer patient only, while in the other cases with tumour no hormonal changes or a paradoxical response were seen after FK 33-824. Based on the fact that an abnormal endocrine response to FK 33-824 has been described in hypothalamic-pituitary disorders, in which anomalous brain opioid activity has been demonstrated, these results suggest the existence of an altered function of the opioid system in cancer patients, the clinical importance of which remains to be determined.

    The discovery of brain tumor-derived cells (BTSC) with the properties of stem cells has led to the formulation of the hypothesis that neural stem cells could be the cell of origin of primary brain tumors (PBT). In this review we present the most common molecular changes in PBT, define the criteria of identification of BTSC and discuss the similarities between the characteristics of these cells and those of the endogenous population of neural stem cells (NPCs) residing in germinal areas of the adult brain. Finally, we propose possible mechanisms of cancer initiation and progression and suggest a model of tumor initiation that includes intrinsic changes of resident NSC and potential changes in the microenvironment defining the niche where the NSC reside.

    Treatment of patients with clinically isolated syndrome (CIS) with disease modifying drugs including interferon β delays conversion to clinically definite multiple sclerosis (MS). However, CIS patients do not necessarily develop MS even after 20 years. Brain MRI lesions were required for CIS patients to include in clinical trials such as CHAMPS study and BENEFIT study. CIS patients with brain MRI lesions compatible to MS were considered as high risk to convert to MS in western countries. Previously we reported that asymptomatic enhancing brain lesions (AEBLs) were found in 9/23 (39.1%) of MS patients who had suffered at least one relapse in the preceding year or two relapses in the preceding 2 years, and the number of AEBLs per scan was 0.37, suggesting low disease activity of Japanese MS patients. We examined brain MRI findings in Japanese CIS patients and compared with those of Japanese MS patients at the first presentation. We reviewed brain MRI of 23 CIS visited our clinic from December 2007 to October 2010 who fulfilled the criteria proposed by Kappos et al. (2006) and Dalton et al (2002). Thirty two clinically definite MS (CDMS) patients fulfilled the first McDonald criteria (two or more attacks and objective clinical evidence of two or more lesions) proposed by Polman et al. (2005). Patients with neuromyelitis optica (NMO) and patients with NMO spectrum proposed by Wingerchuk et al. (2006) and Wingerchuk et al. (2007), respectively, were excluded. Patients with anti-aquaporin4 antibodies or with contiguous spinal cord lesion extending over three vertebral segments on MRI were also excluded. We could not obtain MRI of 11 patients with CDMS because of very long disease course, and 2 CIS and 13 CDMS patients had not been examined with MRI. So we examined 21 CIS and 8 CDMS patients at the first presentation using Paty criteria and Barkhof criteria. Eleven CIS patients did not meet any of the Barkhof criteria.

    Brain cancer and neurological injuries, such as stroke, are life-threatening conditions for which further research is needed to overcome the many challenges associated with providing optimal patient care. Multivariate analysis (MVA) is a class of pattern recognition technique involving the processing of data that contains multiple measurements per sample. MVA can be used to address a wide variety of neuroimaging challenges, including identifying variables associated with patient outcomes; understanding an injury’s etiology, development, and progression; creating diagnostic tests; assisting in treatment monitoring; and more. Compared to adults, imaging of the developing brain has attracted less attention from MVA researchers, however, remarkable MVA growth has occurred in recent years. This paper presents the results of a systematic review of the literature focusing on MVA technologies applied to brain injury and cancer in neurological fetal, neonatal, and pediatric magnetic resonance imaging (MRI). With a wide variety of MRI modalities providing physiologically meaningful biomarkers and new biomarker measurements constantly under development, MVA techniques hold enormous potential toward combining available measurements toward improving basic research and the creation of technologies that contribute to improving patient care.

    Background and objective Airflow limitation in chronic obstructive pulmonary disease (COPD) results in a decrease in oxygen transport to the brain. The aim of the present study was to explore the alteration of spontaneous brain activity induced by hypoxia in patients with COPD. Patients and methods Twenty-five stable patients with COPD and 25 matching healthy volunteers were investigated. Amplitude of low-frequency fluctuation (ALFF) of blood oxygenation level-dependent signal at resting state in the brain was analyzed using functional magnetic resonance imaging. Results Whole-brain analysis using functional magnetic resonance imaging revealed significant decreases in ALFF in the bilateral posterior cingulate gyri and right lingual gyrus and an increase in ALFF in the left postcentral gyrus of patients with COPD. After controlling for SaO2, patients with COPD only showed an increase in ALFF in the left postcentral gyrus. Region of interest analysis showed a decrease in ALFF in the left precentral gyrus and an increase in ALFF in the left caudate nucleus of patients with COPD. In all subjects, ALFF in the bilateral posterior cingulate gyri and right lingual gyrus showed positive correlations with visual reproduction. Conclusion We demonstrated abnormal spontaneous brain activity of patients with COPD, which may have a pathophysiologic meaning. PMID:27555761

    BACKGROUND: The incidence of central nervous system metastasis from primary breast cancer has steadily increased with introduction of more effective molecular-targeted therapies resulting in improved long-term survival. Current standard-of-care treatment modalities for CNS metastases include microsurgical resection, whole-brain radiation therapy, and stereotactic radiosurgery, either alone or in combination. There are currently no FDA-approved drugs with an indication for breast cancer brain metastases. Clearly, there is a dire need to identify biomarkers permitting earlier and accurate diagnosis of CNS metastases, development of prevention strategies in high-risk individuals, and establishing more effective treatment options such as targeted systemic and intrathecal therapies. METHODS: Extracted DNA from metastatic brain tumors (MBTs) and matched tissues from primary breast tumors was quantified and array comparative genomic hybridizations (aCGH) were performed with Agilent SurePrint arrays (G3 ISCA CGH + SNP 180K) using a commercially-available, genetically-normal female DNA standard. Bioinformatics analysis was performed using Agilent CytoGenomics Edition 2.5.8.1. Data were filtered against the Cancer Gene Census (Wellcome Trust Sanger Institute) to identify genes with well-characterized roles in cancer. RESULTS: From genomic copy number data analysis tailored to uncover the most frequent gene aberrations in breast cancer MBTs, we identified that MYC oncogene amplification was among the most common. Pathway analysis of the analyzed gene set of recurring gene aberrations identified the Human Embryonic Stem Cell Pluripotency pathway as being over-represented. The genes in this pathway showing copy number gain include NTRK1, PIK3CA and SOX2. Direct comparisons of MBTs with their matched primary tumor (n = 4) revealed a range of examples for highly similar and divergent patterns of gene aberrations. In one case ERBB2 was confirmed to be in the MBT, and not in the

    The Brain-Expressed X-linked (BEX) family proteins are comprised of five human proteins including BEX1, BEX2, BEX3, BEX4 and BEX5. BEX family proteins are expressed in a wide range of tissues and are known to play a role in neuronal development. Recent studies suggest a role of BEX family proteins in cancers. BEX1 expression is lost in a subgroup of patients with acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). Expression of BEX1 controls cell surface receptor signaling and restores imatinib response in resistant cells. BEX2 is overexpressed in a group of breast cancer patients and also in gliomas. Increased BEX2 expression led to enhanced NF-κB signaling as well as cell proliferation. Although BEX2 acts as tumor promoter in a subset of breast cancer, BEX3 expression displayed an opposite role. Overexpression of BEX3 resulted in inhibition of tumor formation in breast cancer mouse xenograft models. The role of BEX4 and BEX5 in cancer has not yet been defined. Collectively this suggests that BEX family members have distinct roles in cancers. While BEX1 and BEX3 act as tumor suppressors, BEX2 seems to act as an oncogene. PMID:26408910

    Toxoplasma gondii is an intracellular protozoan that can modulate the environment of the infected host. An unfavorable environment modulated by T. gondii in the brain includes tumor microenvironment. Literature has suggested that T. gondii infection is associated with development of brain tumors. However, in Korea, epidemiological data regarding this correlation have been scarce. In this study, in order to investigate the relationship between T. gondii infection and brain tumor development, we investigated the seroprevalence of T. gondii among 93 confirmed brain tumor patients (various histological types, including meningioma and astrocytoma) in Korea using ELISA. The results revealed that T. gondii seropositivity among brain tumor patients (18.3%) was significantly (P<0.05) higher compared with that of healthy controls (8.6%). The seropositivity of brain tumor patients showed a significant age-tendency, i.e., higher in younger age group, compared with age-matched healthy controls (P<0.05). In conclusion, this study supports the close relationship between T. gondii infection and incidence of brain tumors. PMID:27180580

    Purpose: To analyze factors affecting outcomes in breast cancer patients with brain metastases (BM) and characterize the role of HER2 status. Methods and Materials: We identified 264 breast cancer patients treated between 1999 and 2008 for BM. HER2 status was known definitively for 172 patients and was used to define cohorts in which survival and risk factors were analyzed. Results: Kaplan-Meier survival analysis demonstrated improved mean overall survival (105.7 vs. 74.3 months, p < 0.02), survival after diagnosis of BM (neurologic survival, NS) (32.2 vs. 18.9 months, p < 0.01), and survival after treatment with stereotactic radiosurgery (RS) (31.3 vs. 14.1, p < 0.01) in HER2+ patients relative to those with HER2- breast cancer. HER2+ status was an independent, positive prognostic factor for survival on univariate and multivariate hazard analysis (hazard ratio: overall survival = 0.66, 0.18; NS = 0.50, 0.34). Additionally, subgroup analysis suggests that stereotactic radiosurgery may be of particular benefit in patients with HER2+ tumors. Conclusions: Overall survival, NS, and RS are improved in patients with HER2+ tumors, relative to those with HER2- lesions, and HER2 amplification is independently associated with increased survival in patients with BM from breast cancer. Our findings suggest that the prognosis of HER2+ patients may be better than that of otherwise similar patients who are HER2- and that stereotactic radiosurgery may be beneficial for some patients with HER2+ lesions.

    Age-specific analyses of mortality rates in Japan show that cancer was the leading cause of death for the age group 40-89 years in the year 2013. Although the crude mortality rate from cancer has recently increased, the age-adjusted cancer mortality rate has shown a decreasing trend. This suggests that the increases in the crude mortality rate may have been caused by the aging of the population. Cancer patients who are old present many comorbidities and newly diagnosed geriatric problems. Several tools provide determinants of survival in cancer patients who are old (including the comprehensive geriatric assessment [CGA]) in order to improve the quality of cancer care in this population.

    Brain tumors represent the most common solid tumors in childhood, accounting for almost 25% of all childhood cancer, second only to leukemia. Pediatric central nervous system tumors encompass a wide variety of diagnoses, from benign to malignant. Any brain tumor can be associated with significant morbidity, even when low grade, and mortality from pediatric central nervous system tumors is disproportionately high compared to other childhood malignancies. Management of children with central nervous system tumors requires knowledge of the unique aspects of care associated with this particular patient population, beyond general oncology care. Pediatric brain tumor patients have unique needs during treatment, as cancer survivors, and at end of life. A multidisciplinary team approach, including advanced practice nurses with a specialty in neuro-oncology, allows for better supportive care. Knowledge of the unique aspects of care for children with brain tumors, and the appropriate interventions required, allows for improved quality of life. PMID:26245798

    This study was performed to measure regional glucose metabolism in nonaffected brain regions of patients with primary or metastatic brain tumors. Seven female and four male patients (mean age 51.5{plus_minus}14.0 years old) were compared with eleven age and sex matched normal subjects. None of the patients had hydrocephalus and/or increased intracranial pressure. Brain glucose metabolism was measured using FDG-PET scan. Five of the patients were reevaluated one week after receiving radiation treatment (RT) to the brain. Patients were on Decadron and/or Dilantin at the time of both scan. PET images were analyzed with a template of 115 nonoverlapping regions of interest and then grouped into eight gray matter regions on each hemisphere. Brain regions with tumors and edema shown in MR imaging were excluded. Z scores were used to compare individual patients` regional values with those of normal subjects. The number of regional values with Z scores of less than - 3.0 were considered abnormal and were quantified. The mean global glucose metabolic rate (mean of all regions) in nonaffected brain regions of patients was significantly lower than that of normal controls (32.1{plus_minus}9.0 versus 44.8{plus_minus}6.3 {mu}mol/100g/min, p<0.001). Analyses of individual subjects revealed that none of the controls and 8 of the 11 patients had at least one abnormal region. In these 8 patients the regions which were abnormal were most frequently localized in right (n=5) and left occipital (n=6) and right orbital frontal cortex (n=7) whereas the basal ganglia was not affected. Five of the patients who had repeated scans following RT showed decrements in tumor metabolism (41{plus_minus}20.5%) and a significant increase in whole brain metabolism (8.6{plus_minus}5.3%, p<0.001). The improvement in whole brain metabolism after RT suggests that the brain metabolic decrements in the patients were related to the presence of tumoral tissue and not just a medication effect.

    In recent years there has been an increase in the interest of cancer patients in receiving complementary medicine therapies as supportive measures to cure the disease. In response, medical units that combine conventional and complementary medicine (integrative medicine) have been established in leading cancer centers worldwide. In Israel, a special integrative medicine unit that combines mind-body, Chinese medicine, nutrition, herbs, supplements, and manual therapies (such as shiatsu) before, during and after conventional anti-cancer therapies has been established as an integral part of the Davidoff Comprehensive Cancer Center in 2006. Shiatsu represents a group of manual therapeutic techniques, including acupressure. Shiatsu offers cancer patients a non-pharmacologic method to relieve symptoms and improve quality of life throughout the course of illness. Research indicates that acupressure is relatively effective and safe for common cancer-related symptoms such as nausea, vomiting and insomnia. In our experience, shiatsu is also relatively effective and safe for other common symptoms such as fatigue, muscular pain and body image dissatisfaction. Yet, insufficient evidence exists to delineate the best means by which shiatsu and other manual therapies could or should be integrated into routine cancer care. The purpose of the present paper is to describe what is currently known about this topic in order to support decision-making that is based on facts, rather than on myths and misconceptions. We call for more research that examines the effectiveness and safety of shiatsu and other manual therapies in the care of cancer patients. PMID:18935760

    Objective: Based on our previous work in Huntington disease (HD) showing improved energy metabolism in muscle by providing substrates to the Krebs cycle, we wished to obtain a proof-of-concept of the therapeutic benefit of triheptanoin using a functional biomarker of brain energy metabolism validated in HD. Methods: We performed an open-label study using 31P brain magnetic resonance spectroscopy (MRS) to measure the levels of phosphocreatine (PCr) and inorganic phosphate (Pi) before (rest), during (activation), and after (recovery) a visual stimulus. We performed 31P brain MRS in 10 patients at an early stage of HD and 13 controls. Patients with HD were then treated for 1 month with triheptanoin after which they returned for follow-up including 31P brain MRS scan. Results: At baseline, we confirmed an increase in Pi/PCr ratio during brain activation in controls—reflecting increased adenosine triphosphate synthesis—followed by a return to baseline levels during recovery (p = 0.013). In patients with HD, we validated the existence of an abnormal brain energy profile as previously reported. After 1 month, this profile remained abnormal in patients with HD who did not receive treatment. Conversely, the MRS profile was improved in patients with HD treated with triheptanoin for 1 month with the restoration of an increased Pi/PCr ratio during visual stimulation (p = 0.005). Conclusion: This study suggests that triheptanoin is able to correct the bioenergetic profile in the brain of patients with HD at an early stage of the disease. Classification of evidence: This study provides Class III evidence that, for patients with HD, treatment with triheptanoin for 1 month restores an increased MRS Pi/PCr ratio during visual stimulation.

    The scope of supportive care and cancer rehabilitation is very wide and heterogeneous. In this review we focus on nutritional aspects, sexual and gonadal function, psychological rehabilitation, treatment of cancer pain, and rehabilitation of patients with bone metastases. The anorexia-cachexia syndrome is a particularly frequent manifestation of cancer that profoundly affects body image and significantly impairs quality of life of cancer patients. However, enteral feeding through nasogastric tubes, gastrostomies, or jejunostomies is an efficient method for providing long-term enteral nutrition at home and for contributing to complete rehabilitation after cancer therapy. Recent effort has focused on nutritional pharmacology and on the optimalization of the use of appetite-stimulating drugs, such as progestational agents. The psychological components of cancer, anticancer therapy, and quality of life have now been widely recognized and studied. Effective pharmacological and psychotherapeutic interventions help patients and their family to better adjust to the chronic stress of cancer, but more specific determinants of psychological morbidity should be developed. In particular, the safe and efficient use of the most recent classes of antidepressants and anxiolytics should be urgently studied. More than 90% of cancer patients present one or more pain syndromes during their illness. The adequate use of drugs is the cornerstone of treatment. The development on new molecules and new routes of administration opens interesting perspectives for cancer pain control. Bone metastases are the source of considerable morbidity. Intravenous bisphosphonates have been successfully used for the treatment of the symptoms of metastatic bone disease, especially bone pain. Moreover, monthly pamidronate infusions in addition to chemotherapy reduce the mean skeletal morbidity rate by more than one third and contribute to the rehabilitation of cancer patients with bone metastases from breast

    Abstract This study aimed to evaluate cancer risk and possible risk factors in patients diagnosed with empyema. A total of 31,636 patients with newly diagnosed empyema between January 1, 1999 and December 31, 2010 were included in this study. Standardized incidence ratios (SIRs) were calculated to compare the cancer incidence in these empyema patients to that in the general population. Adjusted hazard ratios were also calculated to investigate whether characteristics increased cancer risk. During the 12-year study period, 2,654 cancers occurred in 31,636 patients with empyema, yielding an SIR of 2.67 (95% confidence interval [CI] 2.57–2.78). We excluded cancer that occurred within 1 year to avoid surveillance bias. The cancer risk remained significantly increased (SIR 1.50, 95% CI 1.41–1.58). Specifically, patients with empyema had higher SIR of cancers of the head and neck (1.50, 95% CI 1.41–1.58), esophagus (2.56, 95% CI 1.92–3.33), stomach (1.49, 95% CI 1.16–1.89), liver and biliary tract (2.18, 95% CI 1.93–2.45), and lung and mediastinum (1.62, 95% CI 1.39–1.86). Age ≥ 60, male sex, diabetes mellitus, and liver cirrhosis were independent risk factors for cancer development. Our study demonstrates an increased incidence of cancer development in patients with empyema, and patients’ age ≥ 60, men, and those with diabetes mellitus and liver cirrhosis showed a higher incidence of developing cancer compared to the general population. The association between such kind of infection and secondary malignancy may be elucidated by further study. PMID:26945399

    This study was conducted for the purpose of describing cancer patients' satisfaction with their care when they had to travel unexpectedly away from home for treatment. Ontario initiated a rereferral program for cancer patients who needed radiation therapy when the waiting lists in southern Ontario became lengthy. Patients travelled to the United States or northern Ontario for their care. A standardized survey containing 25 items with five-point Likert scale responses was mailed to all patients who participated in the rereferral program, following completion of their treatment. Items covered patient experiences before leaving home, in preparing for travel, and staying at the cancer facilities away from home. A total of 466 (55.8%) patients returned the survey. Overall, patients were satisfied with their care. However, there were a number of areas identified by patients where improvements could be made. These areas included access to support prior to leaving home, access to information about supportive care services while away from home, and sensitivity to personal needs in making arrangements for travel. Provision of information and support are important to cancer patients having to travel for cancer treatment. PMID:15969333

    Psychiatric management of patients with breast cancer, as well as women's emotional reactions to all phases of breast cancer, were reviewed. These patients face two major losses; one is the physical loss of part of the body and a threat to life, and the other is the loss of femininity. The patients are also likely to suffer from various psychiatric problems including anxiety and depression. Oncologists should be alert to each patient's emotional reactions and potential psychiatric problems, and if necessary, should refer them to a psychiatrist. A combination of psychotherapeutic, behavioural, and pharmacologic techniques is available for the care of patients with breast cancer. Psychotherapeutic modalities include individual therapy, family therapy, group therapy, and self-help treatment. The author divided individual therapy into general and specific treatment. General treatment deals with a crisis-intervention and cognitive-behavioral approach, whereas specific treatment deals with issues relevant to patients with breast cancer. Some of the therapeutic processes were illustrated in a case report. These guidelines will contribute to the relief and prevention of emotional suffering stemming from an encounter with the most common form of cancer in women. Also, proper and effective care for patients with breast cancer requires combined use of a variety of therapeutic modalities as well as a multi-disciplinary approach including psychiatric care.

    Background. Posterior reversible encephalopathy syndrome (PRES) is characterized by neurologic symptoms with typical lesions on neuroimaging and may be associated with chemotherapy and immunosuppressive agents used in patients with cancer. We described the spectrum of PRES at a major cancer center. Methods. We reviewed charts of adults with PRES between 2005 and 2011 at Memorial Sloan Kettering Cancer Center for clinical information and outcome. Results. We identified 21 women (68%) and 10 men (median cohort age: 58 years). Solid tumors (n = 22, 71%) were more common than hematologic (n = 8) or primary brain malignancies (n = 1). Prior brain irradiation (16%) and central nervous system metastases (10%) were uncommon. There were 55% who received chemotherapy or targeted therapy within the month preceding PRES, including 6 patients who received bevacizumab; PRES followed allogeneic stem cell transplantation in 5 (16%). Presenting symptoms included confusion (71%), seizure (58%), and headache (48%). Maximum systolic and diastolic blood pressures were similar among patients grouped by cancer type, chemotherapy or bevacizumab use, and atypical imaging. Moreover, 37% of patients with both magnetic resonance imaging (MRI) and computed tomography (CT) had normal CT concurrent with PRES on MRI, and 84% returned to neurologic baseline at a median of 7.5 days (range: 1–167 days) from onset. Successful anticonvulsant taper was achieved in 51%. Chemotherapy rechallenge was attempted in 41% without recurrent PRES. Autopsy revealed nonspecific changes isolated to radiographically affected areas in one of two patients. Conclusion. Recent chemotherapy, particularly bevacizumab, is common in cancer patients with PRES. Clinical and radiographic presentations may vary; MRI appears more sensitive than CT. Anticonvulsant taper and chemotherapy rechallenge is often possible. Implications for Practice: Posterior reversible encephalopathy syndrome is characterized by neurologic symptoms

    The Bayesian network (BN) is a promising method for modeling cancer metastasis under uncertainty. BN is graphically represented using bioinformatics variables and can be used to support an informative medical decision/observation by using probabilistic reasoning. In this study, we propose such a BN to describe and predict the occurrence of brain metastasis from lung cancer. A nationwide database containing more than 50,000 cases of cancer patients from 1996 to 2010 in Taiwan was used in this study. The BN topology for studying brain metastasis from lung cancer was rigorously examined by domain experts/doctors. We used three statistical measures, namely, the accuracy, sensitivity, and specificity, to evaluate the performances of the proposed BN model and to compare it with three competitive approaches, namely, naive Bayes (NB), logistic regression (LR) and support vector machine (SVM). Experimental results show that no significant differences are observed in accuracy or specificity among the four models, while the proposed BN outperforms the others in terms of sampled average sensitivity. Moreover the proposed BN has advantages compared with the other approaches in interpreting how brain metastasis develops from lung cancer. It is shown to be easily understood by physicians, to be efficient in modeling non-linear situations, capable of solving stochastic medical problems, and handling situations wherein information are missing in the context of the occurrence of brain metastasis from lung cancer.

    The aim was to describe male cancer survivors' barriers towards participation in cancer rehabilitation as a means to guiding future targeted men's cancer rehabilitation. Symbolic Interactionism along with the interpretive descriptive methodology guided the study of 35 male cancer survivors representing seven cancer types. Data were generated through a 5-month fieldwork study comprising participant observations, semi-structured individual interviews and informal conversations. The analyses revealed two overarching findings shedding light on male cancer survivors' barriers to rehabilitation: 'Fear of losing control' and 'Striving for normality'. While 'Fear of losing control' signified what the men believed rehabilitation would invoke: 'Reduced manliness', 'Sympathy and dependency' and 'Confrontation with death', 'Striving for normality' was based on what the men believed rehabilitation would hinder: 'Autonomy and purpose', 'Solidarity and fellowship' and 'Forget and move on'. This study of male cancer survivors' and cancer rehabilitation documents how masculine ideals may constitute barriers for participation in rehabilitation and provides insights about why men are underrepresented in rehabilitation. The findings can guide practice to develop research-based rehabilitation approaches focused on preserving control and normality. Further empirical evidence is needed to: (1) explore the conduct of health professionals' towards male cancer patients and (2) address gender inequalities in cancer rehabilitation. PMID:26223855

    Purpose: To assess the incidence of early delayed or late morbidity of Brain after particle therapy for skull base tumors and head-and-neck cancers. Methods and Materials: Between May 2001 and December 2005, 59 patients with cancerous invasion of the skull base were treated with proton or carbon ion therapy at the Hyogo Ion Beam Medical Center. Adverse events were assessed according to the magnetic resonance imaging findings (late effects of normal tissue-subjective, objective, management, analytic [LENT-SOMA]) and symptoms (Common Terminology Criteria for Adverse Events [CTCAE], version 3.0). Dose-volume histograms were used to analyze the relationship between the dose and volume of the irradiated brain and the occurrence of brain injury. The median follow-up time was 33 months. Results: Of the 48 patients treated with proton therapy and 11 patients treated with carbon ion radiotherapy, 8 (17%) and 7 (64%), respectively, developed radiation-induced brain changes (RIBCs) on magnetic resonance imaging (LENT-SOMA Grade 1-3). Four patients (7%) had some clinical symptoms, such as vertigo and headache (CTCAE Grade 2) or epilepsy (CTCAE Grade 3). The actuarial occurrence rate of RIBCs at 2 and 3 years was 20% and 39%, respectively, with a significant difference in the incidence between the proton and carbon ion radiotherapy groups. The dose-volume histogram analyses revealed significant differences between Brain lobes with and without RIBCs in the actuarial volume of brain lobes receiving high doses. Conclusion: Particle therapies produced minimal symptomatic brain toxicities, but sequential evaluation with magnetic resonance imaging detected a greater incidence of RIBCs. Significant differences were observed in the irradiated brain volume between Brain lobes with and without RIBCs.

    Brain metastases are a frequent finding in patients with non-small cell lung cancer (NSCLC). The present case reports the clinical course of a patient who was treated with gefitinib alone for progressive brain metastases after whole-brain irradiation treatment (WBRT). A 50-year-old women with primary stage IV NSCLC (bone metastases) developed brain metastases after 3 cycles of chemotherapy consisting of paclitaxel and carboplatin (CBDA). After completion of the WBRT, magnetic resonance imaging (MRI) indicated further progression. Two cycles of temozolomide and topotecan were applied; this was ineffective in preventing central nervous system progression. For symptomatic brain metastatic disease the patient received gefitinib as single-agent treatment. Within a few weeks of treatment there was an obvious clinical improvement. Follow-up of the brain 2 months after the start of treatment showed a decrease in both the size and number of brain metastases. Additional manifestations in the lungs and the skeletal system were re-assessed as stable disease during the treatment with gefitinib. Within 4 months of treatment there were no side-effects such as skin rash or any other systemic toxicity. Gefitinib may therefore have a role in the treatment of brain metastases from NSCLC.

    Monocarboxylate transporters (MCTs) constitute a family of 14 members among which MCT1-4 facilitate the passive transport of monocarboxylates such as lactate, pyruvate and ketone bodies together with protons across cell membranes. Their anchorage and activity at the plasma membrane requires interaction with chaperon protein such as basigin/CD147 and embigin/gp70. MCT1-4 are expressed in different tissues where they play important roles in physiological and pathological processes. This review focuses on the brain and on cancer. In the brain, MCTs control the delivery of lactate, produced by astrocytes, to neurons, where it is used as an oxidative fuel. Consequently, MCT dysfunctions are associated with pathologies of the central nervous system encompassing neurodegeneration and cognitive defects, epilepsy and metabolic disorders. In tumors, MCTs control the exchange of lactate and other monocarboxylates between glycolytic and oxidative cancer cells, between stromal and cancer cells and between glycolytic cells and endothelial cells. Lactate is not only a metabolic waste for glycolytic cells and a metabolic fuel for oxidative cells, but it also behaves as a signaling agent that promotes angiogenesis and as an immunosuppressive metabolite. Because MCTs gate the activities of lactate, drugs targeting these transporters have been developed that could constitute new anticancer treatments.

    Objective: The treatment of patients with cancer has advanced into a complex, multimodal approach incorporating surgery, radiation, and chemotherapy. Managing wounds in this population is complicated by tumor biology, the patient's disease state, and additional comorbidities, some of which may be iatrogenic. Radiation therapy, frequently employed for local-regional control of disease following surgical resection, has quantifiable negative healing effects due to local tissue fibrosis and vascular effects. Chemotherapeutic agents, either administered alone or as combination therapy with surgery and radiation, may have detrimental effects on the rapidly dividing tissues of healing wounds. Overall nutritional status, often diminished in patients with cancer, is an important aspect to the ability of patients to heal after surgical procedures and/or treatment regimens. Methods: An extensive literature search was performed to gather pertinent information on the topic of wound healing in patients with cancer. The effects that surgical procedures, radiation therapy, chemotherapy, and nutritional deficits play in wound healing in these patients were reviewed and collated. Results: The current knowledge and treatment of these aspects of wound healing in cancer patients are discussed, and observations and recommendations for optimal wound healing results are considered. Conclusion: Although wound healing may proceed in a relatively unimpeded manner for many patients with cancer, there is a potential for wound failure due to the nature and effects of the oncologic disease process and its treatments.

    Breast cancer is the most prevalent malignancy among women under 50. Improvements in diagnosis and treatment have yielded an important decrease in mortality in the last 20 years. In many cases, chemotherapy and radiotherapy develop side effects on the reproductive function. Therefore, before the anti-cancer treatment impairs fertility, clinicians should offer some techniques for fertility preservation for women planning motherhood in the future. In order to obtain more available oocytes for IVF, the ovary must be stimulated. New protocols which prevent exposure to increased estrogen during gonadotropin stimulation, measurements to avoid the delay in starting anti-cancer treatment or the outcome of ovarian stimulation have been addressed in this review. There is no evidence of association between ovarian stimulation and breast cancer. It seems that there are more relevant other confluent factors than ovarian stimulation. Factors that can modify the risk of breast cancer include: parity, age at full-term birth, age of menarche, and family history. There is an association between breast cancer and exogenous estrogen. Therefore, specific protocols to stimulate patients with breast cancer include anti-estrogen agents such as letrozole. By using letrozole plus recombinant follicular stimulating hormone, patients develop a multifollicular growth with only a mild increase in estradiol serum levels. Controlled ovarian stimulation (COS) takes around 10 days, and we discuss new strategies to start COS as soon as possible. Protocols starting during the luteal phase or after inducing the menses currently prevent a delay in starting ovarian stimulation. Patients with breast cancer have a poorer response to COS compared with patients without cancer who are stimulated with conventional protocols of gonadotropins. Although many centres offer fertility preservation and many patients undergo ovarian stimulation, there are not enough studies to evaluate the recurrence, breast cancer

    Background The etiology of childhood brain cancer remains largely unknown. However, previous studies have yielded suggestive associations with parental pesticide use. Objectives We aimed to evaluate parental exposure to pesticides at home and on the job in relation to the occurrence of brain cancer in children. Methods We included 526 one-to-one–matched case–control pairs. Brain cancer cases were diagnosed at < 10 years of age, and were identified from statewide cancer registries of four U.S. Atlantic Coast states. We selected controls by random digit dialing. We conducted computer-assisted telephone interviews with mothers. Using information on residential pesticide use and jobs held by fathers during the 2-year period before the child’s birth, we assessed potential exposure to insecticides, herbicides, and fungicides. For each job, two raters independently classified the probability and intensity of exposure; 421 pairs were available for final analysis. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using conditional logistic regression, after adjustment for maternal education. Results A significant risk of astrocytoma was associated with exposures to herbicides from residential use (OR = 1.9; 95% CI, 1.2–3.0). Combining parental exposures to herbicides from both residential and occupational sources, the elevated risk remained significant (OR = 1.8; 95% CI, 1.1–3.1). We observed little association with primitive neuroectodermal tumors (PNET) for any of the pesticide classes or exposure sources considered. Conclusions Our observation is consistent with a previous literature reporting suggestive associations between parental exposure to pesticides and risk of astrocytoma in offspring but not PNET. However, these findings should be viewed in light of limitations in exposure assessment and effective sample size. PMID:19590697

    We report the case of a 48-year-old female patient with HER2-positive and hormone receptor-negative breast cancer with multiple liver metastases. She underwent 6 cycles of FEC followed by docetaxel plus trastuzumab (TZB), resulting in a clinical complete response. After 15 cycles of a TZB-containing regimen, she complained of dizziness and nausea, and imaging examinations revealed multiple brain metastases. Whole-brain irradiation(33.6 Gy) was performed, and the chemotherapy regimen was changed to lapatinib (LAP: orally at 1,250 mg/day, every day) and capecitabine (CAP: orally at 2,000 mg/m2, every day for 2 weeks, followed by a 1-week rest interval, as 1 cycle). After 6 weeks of the new treatment, magnetic resonance imaging revealed marked shrinkage of brain metastases. A clinical complete response was maintained for 19 months. While brain metastasis is an important problem with treatment with TZB, LAP is drawing attention because of its ability to pass the blood-brain barrier because of its small molecular weight. LAP/CAP combination therapy may be an effective treatment option for brain metastases of HER2-positive breast cancer in which TZB essentially has no effect. PMID:26199252

    We propose that stem cell therapy may be a potent treatment for metastatic melanoma in the brain. Here we discuss the key role of a leaky blood-brain barrier (BBB) that accompanies the development of brain metastases. We review the need to characterize the immunological and inflammatory responses associated with tumor-derived BBB damage in order to reveal the contribution of this brain pathological alteration to the formation and growth of brain metastatic cancers. Next, we discuss the potential repair of the BBB and attenuation of brain metastasis through transplantation of bone marrow-derived mesenchymal stem cells with the endothelial progenitor cell phenotype. In particular, we review the need for evaluation of the efficacy of stem cell therapy in repairing a disrupted BBB in an effort to reduce neuroinflammation, eventually attenuating brain metastatic cancers. The demonstration of BBB repair through augmented angiogenesis and vasculogenesis will be critical to establishing the potential of stem cell therapy for the treatment/prevention of metastatic brain tumors. The overarching hypothesis we advanced here is that BBB breakdown is closely associated with brain metastatic cancers of melanoma, exacerbating the inflammatory response of the brain during metastasis, and ultimately worsening the outcome of metastatic brain cancers. Abrogating this leaky BBB-mediated inflammation via stem cell therapy represents a paradigm-shifting approach to treating brain cancer. This review article discusses the pros and cons of cell therapy for melanoma brain metastases. PMID:25310691

    The purpose of the study was to assay monoamines in cerebrospinal fluid (CSF) obtained from the trigeminal cistern of 64 patients with intractable facial pain. The CSF was analyzed for homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA), and 3-methoxy-4-hydroxyphenylglycol (MHPG), end-product markers of activity for the dopamine, serotonin, and norepinephrine systems, respectively. HVA averaged 121 ng/mL in these facial pain patients, compared to 150 to 550 ng/mL in 10 studies of ventricular brain CSF in assorted psychiatric and pain patients. 5-HIAA averaged 29 to ng/mL in our facial pain patients compared to 60 to 120 ng/mL in nine studies of ventricular brain CSF in assorted psychiatric and neurological patients. Trigeminal cistern CSF MHPG averaged 9 ng/mL, similar to the range of 13 studies of lumbar CSF of assorted psychiatric and pain diagnoses. These results indicate that (1) the electrochemical detection method provides a unique way of accurately measuring nanogram concentrations of multiple monoamines in a little as 0.25 mL of CSF; (2) trigeminal cistern and posterior fossa brain CSF monoamine metabolites reflect a different profile of dopaminergic and serotonergic functioning in these facial pain patients from that previously reported with lumbar CSF measurements of other patients; and (3) trigeminal sensory ganglion or brain dopamine and serotonin systems may be concomitantly dysfunctional in intractable facial pain.

    Since cancer incidence tends to increase with age, health professionals will encounter ever-greater numbers of older people with cancer. Elderly cancer patients present complex problems that need comprehensive physical and psychosocial support. In order to give specialised care to this segment of the population, a multidisciplinary approach must be used; only in this way can an individualised treatment program be provided. Oncology nurses are an important component of this team and can contribute significantly to the panorama of needs of this segment of the population, which include the prevention and early detection of cancer, the use of state-of-the-art treatments, patient education, care during and after hospitalisation and quality of life (QOL) issues. In this way, the older person with cancer can be treated in an optimal manner and survival can hopefully be improved in a meaningful way. PMID:11500265

    The sequential application of whole brain radiotherapy (WBRT) and more targeted stereotactic radiosurgery (SRS) is frequently used to treat metastatic brain tumors. However, SRS has side effects related to necrosis and edema, and requires separate and relatively invasive localization procedures. Helical tomotherapy (HT) allows for a SRS-type simultaneous infield boost (SIB) of multiple brain metastases, synchronously with WBRT and without separate stereotactic procedures. However, some patients' tumors may not respond to HT+SIB, and would be more appropriately treated with radiosurgery or conventional surgery despite the additional risks and side effects. As a first step toward a broader objective of developing a means for response prediction to HT+SIB, the goal of this study was to investigate whether quantitative measurements of tumor size and appearance (including first- and second-order texture features) on a magnetic resonance imaging (MRI) scan acquired prior to treatment could be used to differentiate responder and nonresponder patient groups after HT+SIB treatment of metastatic disease of the brain. Our results demonstrated that smaller lesions may respond better to this form of therapy; measures of appearance provided limited added value over measures of size for response prediction. With further validation on a larger data set, this approach may lead to a means for prediction of individual patient response based on pre-treatment MRI, supporting appropriate therapy selection for patients with metastatic brain cancer.

    Although many schizencephaly patients suffer from epilepsy, the relationship between schizencephalic lesions and epileptic foci remains unclear. Previous studies have shown that schizencephalic lesions may be associated with, rather than contain, epileptogenic zones. Thus, the purpose of this study was to investigate the current source distribution (CSD) of epileptiform discharges in schizencephalic patients and to correlate this activity with existing structural lesions. A consecutive series of 30 schizencephalic patients who were diagnosed using brain magnetic resonance imaging (MRI) were selected retrospectively and prospectively. Of the original 30 subjects selected, 13 had epilepsy, and 6 of these patients exhibited schizencephaly, epilepsy, and interictal spikes on electroencephalograms (EEG) and were enrolled in the present study investigating the current source analysis of interictal spikes. The CSDs of the initial rising phases and the peak points of the interictal spikes were obtained using standardized low-resolution brain electromagnetic tomography (LORETA). Five patients exhibited a single focus of interictal spikes, while 1 patient showed 2 foci. Relative to the structural brain lesions, 5 patients displayed extrinsically localized CSDs, while 1 patient showed a partially intrinsically localized CSD. The present findings demonstrate that the CSDs of interictal spikes in schizencephalic patients are in general anatomically distinct from the cerebral schizencephalic lesions and that these lesions may display an extrinsic epileptogenicity.

    With improved survival rates among cancer patients, fertility preservation is now being recognized as an issue of great importance. There are currently several methods of fertility preservation available in female cancer patients and the options and techniques via assisted reproduction and cryopreservation are increasing, but some are still experimental and continues to be evaluated. The established means of preserving fertility include embryo cryopreservation, gonadal shielding during radiation therapy, ovarian transposition, conservative gynecologic surgery such as radical trachelectomy, donor embryos/oocytes, gestational surrogacy, and adoption. The experimental methods include oocyte cryopreservation, ovarian cryopreservation and transplantation, in vitro maturation, and ovarian suppression. With advances in methods for the preservation of fertility, providing information about risk of infertility and possible options of fertility preservation to all young patients with cancer, and discussing future fertility with them should be also considered as one of the important parts of consultation at the time of cancer diagnosis.

    Maintenance of adequate oxygenation is a mainstay of intensive care, however, recommendations on the safety, accuracy, and the potential clinical utility of invasive and non-invasive tools to monitor brain and systemic oxygenation in neurocritical care are lacking. A literature search was conducted for English language articles describing bedside brain and systemic oxygen monitoring in neurocritical care patients from 1980 to August 2013. Imaging techniques e.g., PET are not considered. A total of 281 studies were included, the majority described patients with traumatic brain injury (TBI). All tools for oxygen monitoring are safe. Parenchymal brain oxygen (PbtO2) monitoring is accurate to detect brain hypoxia, and it is recommended to titrate individual targets of cerebral perfusion pressure (CPP), ventilator parameters (PaCO2, PaO2), and transfusion, and to manage intracranial hypertension, in combination with ICP monitoring. SjvO2 is less accurate than PbtO2. Given limited data, NIRS is not recommended at present for adult patients who require neurocritical care. Systemic monitoring of oxygen (PaO2, SaO2, SpO2) and CO2 (PaCO2, end-tidal CO2) is recommended in patients who require neurocritical care. PMID:25208670

    The disorders of consciousness refer to clinical conditions that follow a severe head injury. Patients diagnosed as in a vegetative state lack awareness, while patients diagnosed as in a minimally conscious state retain fluctuating awareness. However, it is a challenge to accurately diagnose these disorders with clinical assessments of behavior. To improve diagnostic accuracy, neuroimaging-based approaches have been developed to detect the presence or absence of awareness in patients who lack overt responsiveness. For the small subset of patients who retain awareness, brain-computer interfaces could serve as tools for communication and environmental control. Here we review the existing literature concerning the sensory and cognitive abilities of patients with disorders of consciousness with respect to existing brain-computer interface designs. We highlight the challenges of device development for this special population and address some of the most promising approaches for future investigations. PMID:27590972

    Using MRI survey, 163 patients with various brain pathology of vascular genesis were studied. Vascular dementia according to NINDS-AIREN classification was diagnosed in 15% of patients. Cognitive disturbances in other patients did not reach a level of dementia. A control group comprised 61 subjects without rough structural changes on MRI and cognitive dysfunction. Motor disorders were estimated according to classification of J. Nutt et al. (1993), quantitative static changes were registered using computer stabilography. The results of the study showed that postural instability occurs in 100% of patients with vascular brain pathology. A degree of its expression elevated in direct proportion to the expression of cognitive disturbances, reaching a maximum in patients with dementia. PMID:15581031

    The resonance Raman (RR) spectra of six types of human brain tissues are examined using a confocal micro-Raman system with 532-nm excitation in vitro. Forty-three RR spectra from seven subjects are investigated. The spectral peaks from malignant meningioma, stage III (cancer), benign meningioma (benign), normal meningeal tissues (normal), glioblastoma multiforme grade IV (cancer), acoustic neuroma (benign), and pituitary adenoma (benign) are analyzed. Using a 532-nm excitation, the resonance-enhanced peak at 1548 cm-1 (amide II) is observed in all of the tissue specimens, but is not observed in the spectra collected using the nonresonance Raman system. An increase in the intensity ratio of 1587 to 1605 cm-1 is observed in the RR spectra collected from meningeal cancer tissue as compared with the spectra collected from the benign and normal meningeal tissue. The peak around 1732 cm-1 attributed to fatty acids (lipids) are diminished in the spectra collected from the meningeal cancer tumors as compared with the spectra from normal and benign tissues. The characteristic band of spectral peaks observed between 2800 and 3100 cm-1 are attributed to the vibrations of methyl (-CH3) and methylene (-CH2-) groups. The ratio of the intensities of the spectral peaks of 2935 to 2880 cm-1 from the meningeal cancer tissues is found to be lower in comparison with that of the spectral peaks from normal, and benign tissues, which may be used as a distinct marker for distinguishing cancerous tissues from normal meningeal tissues. The statistical methods of principal component analysis and the support vector machine are used to analyze the RR spectral data collected from meningeal tissues, yielding a diagnostic sensitivity of 90.9% and specificity of 100% when two principal components are used.

    Pain in patients with cancer can be refractory to pharmacological treatment or intolerable side effects of pharmacological treatment may seriously disturb patients' quality of life. Specific interventional pain management techniques can be an effective alternative for those patients. The appropriate application of these interventional techniques provides better pain control, allows the reduction of analgesics and hence improves quality of life. Until recently, the majority of these techniques are considered to be a fourth consecutive step following the World Health Organization's pain treatment ladder. However, in cancer patients, earlier application of interventional pain management techniques can be recommended even before considering the use of strong opioids. Epidural and intrathecal medication administration allow the reduction of the daily oral or transdermal opioid dose, while maintaining or even improving the pain relief and reducing the side effects. Cervical cordotomy may be considered for patients suffering with unilateral pain at the level below the dermatome C5. This technique should only be applied in patients with a life expectancy of less than 1 year. Plexus coeliacus block or nervus splanchnicus block are recommended for the management of upper abdominal pain due to cancer. Pelvic pain due to cancer can be managed with plexus hypogastricus block and the saddle or lower end block may be a last resort for patients suffering with perineal pain. Back pain due to vertebral compression fractures with or without pathological tumor invasion may be managed with percutaneous vertebroplasty or kyphoplasty. All these interventional techniques should be a part of multidisciplinary patient program. PMID:21679293

    As therapies continue to increase the lifespan of patients with breast cancer, the incidence of brain metastases has steadily increased, affecting a significant number of patients with metastatic disease. However, a major barrier toward treating these lesions is the inability of therapeutics to penetrate into the central nervous system and accumulate within intracranial tumor sites. In this study, we designed a cell-penetrating gold nanoparticle platform to increase drug delivery to brain metastatic breast cancer cells. TAT peptide-modified gold nanoparticles carrying doxorubicin led to improved cytotoxicity toward two brain metastatic breast cancer cell lines with a decrease in the IC50 of at least 80% compared to free drug. Intravenous administration of these particles led to extensive accumulation of particles throughout diffuse intracranial metastatic microsatellites with cleaved caspase-3 activity corresponding to tumor foci. Furthermore, intratumoral administration of these particles improved survival in an intracranial MDA-MB-231-Br xenograft mouse model. Our results demonstrate the promising application of gold nanoparticles for improving drug delivery in the context of brain metastatic breast cancer. PMID:27169484

    Three "split brain" subjects with normal peripheral hearing were tested on identifying monaurally presented auditory intensity and frequency patterns. One subject was tested before commissurotomy, ten days later, and one year after surgery. Results indicated that sectioning the corpus callosum dramatically affects the ability to verbally report both intensity and frequency patterns. However, the ability of the subjects to correctly "hum" frequency patterns was not impaired. Thus, it appears for a correct verbal report of an auditory pattern, interhemispheric transfer of acoustic information is required, while "humming" the pattern does not. Further application of this finding implicates auditory pattern tasks as as a potentially valuable test for detecting problems of higher auditory processing, particularly those affecting interhemispheric interaction.

    Breast cancer is the most common neoplasm in women and accounts for 26% (182,460) of all new cancer cases among women. With the use of screening mammography and advancement in other diagnostic modalities, many cases of breast cancer now can be diagnosed and treated at early stages of the disease. Unfortunately, adjuvant chemotherapy regimens commonly used in the treatment of breast cancer may cause premature ovarian failure due to their cytotoxic effects on the germ cells in the ovary. Therefore preservation of fertility in breast cancer survivors at reproductive age has become an important quality of life issue. Fertility preservation is a recently emerged field of reproductive medicine that may help protect the reproductive capability of the cancer survivors and allow them to have children in the future. Embryo freezing is the most established fertility preservation strategy. But conventional ovarian stimulation protocols are contraindicated in breast cancer patients because of the rise of estrogen and its metabolites to supraphysiological levels. Recently developed ovarian stimulation protocols with aromatase inhibitor letrozole and tamoxifen appear to provide a safe stimulation with endogenous estrogen levels comparable with those achieved in the natural cycle. Oocyte freezing can be considered in single women and in those who do not wish donor sperm. Ovarian tissue freezing could also be an option in breast cancer patients who do not wish or have a time for an in vitro fertilization cycle, which requires 10 to 14 days of ovarian stimulation.

    OBJECTIVE: A significant number of breast cancer patients, during their life with the diagnosis, experience emotional distress in the form of depression and anxiety. Psychological resilience is the ability of a person to protect his/her mental health when faced with adverse circumstances such as the cancer diagnosis. This study aims to assess the resilience in breast cancer patients and to explore whether depression affects the resilience. MATERIAL AND METHODS: Two hundred eighteen (218) women, treated for early breast cancer responded to Connor - Davidson Resilience Scale and Hospital Depression and Anxiety Scale, in order to assess the level of psychological resilience and the level of depression. RESULTS: There is a significant negative correlation between depression and resilience in our sample (r = - 0.562, p < 0.001). Individuals with higher levels of depression have lower levels of psychological resilience. There is no statistically significant correlation between the ages of the participants; time passed since diagnosis, cancer stage and resilience levels. CONCLUSION: This study shows that patients who are less depressed have higher levels of resilience and that psychological resilience may independently contribute to lower levels of depression among breast cancer patients. The level of psychological resilience may be a protective factor for depression and psychological distress.

    Patients not older than 40 years are referred to as young patients. These women benefit from chemo-, endocrine and anti-HER2 therapy to a similar degree as older women. Surgery and radiation therapy also follow the same recommendations. This manuscript deals with the following topics that need special consideration in young women: endocrine therapy and ovarian suppression; fertility protection and family planning; and genetic counselling. There is an on-going debate on whether tamoxifen is sufficient as an endocrine treatment in young patients with endocrine-responsive tumours or whether suppression of ovarian function in combination with tamoxifen or aromatase inhibitor should be preferred. Recent data suggest a benefit from ovarian suppression plus exemestane in women of 35 years or younger with high-risk breast cancer. However, increased side effects bear the risk of lesser compliance, which eventually results in higher mortality. Child bearing is nowadays frequently postponed to the 4th decade of life, thereby increasing the number of women who have not yet finished their reproductive desires when diagnosed with breast cancer. These patients are in urgent need of counselling for fertility protection. Breast cancer diagnosis at young age is an indication for a possible mutation in breast cancer susceptibility genes. This has an impact on the cancer risk of the whole family, especially the offspring. Drugs that are specifically targeted to cancer cells with genetic alterations that impair DNA repair are already entering the arsenal of oncologists. PMID:27031253

    Myofascial pain syndrome is started to be recognized as one of important factors of pain in cancer patients. However, no reports on features of myofascial trigger points were found in terminally-ill cancer populations. This time, we encountered 5 patients with myofascial pain syndrome and terminal cancer in whom delirium developed due to increased doses of opioid without a diagnosis of myofascial pain syndrome on initial presentation. The delirium subsided with dose reductions of opioid and treatment of myofascial pain syndrome. The common reason for a delayed diagnosis among the patients included an incomplete palpation of the painful sites, which led to unsuccessful myofascial trigger points identification. The features of myofascial trigger points included single onset in the cancer pain management site with opioid and the contralateral abdominal side muscles of the non-common sites. Withdrawal reflexes associated with cancer pain in the supine position, which are increasingly seen in the terminal cancer patients, were considered to have contributed to this siuation. We consider that careful palpation of the painful site is important, in order to obtain greater knowledge and understanding of the features of myofascial trigger points. PMID:26962285

    Guidelines for psychosocial care of cancer patients. The Italian Association of Medical Oncologists published in 2013 the update of the first edition of the Psychosocial Guidelines for the care of cancer patients. The guidelines, produced by a multidisciplinary group (medical doctors, nurses, oncologists, psychologists and patients) aim at recognizing the importance of psychosocial care in helping the patients and their relatives to overcome the effects of the diagnosis and the treatments on mental health and emotional wellbeing. In some cases the evidences available are not as hard as those supporting drug treatments: many outcomes such as the effectiveness of educational interventions, the patients' wellbeing, thrust, perception of support, for their nature and complexity require both quantitative and qualitative measurements. Lack of robust evidences such as those obtained from clinical trials, does not necessarily correspond to lack of effectiveness of the intervention nor should make us forget that patients' rights (to good care, information and support) should be guaranteed.

    More than half of all cancer patients now use some form of complementary/alternative medicine, yet the majority of these patients do not disclose this use to their physicians. Health care practitioners need to educate themselves about the complementary/alternative medicine products their patients are using. Eight herbal products (astragalus, essiac, Asian ginseng, Siberian ginseng, green tea, garlic, Hoxsey formula and iscador) commonly used by cancer patients are reviewed here and a list of recommended reference texts is provided. In addition, health care providers are encouraged to initiate discussions about complementary/alternative products and therapies with their patients so that they may help them make safe and informed decisions about these products. Not knowing what patients are taking is definitely a less desirable option. PMID:14528703

    Importance of the field: Many promising targeted agents and combination therapies are being investigated for brain cancer. However, the results from recent clinical trials have been disappointing. A better understanding of the disposition of drug in the brain early in drug development would facilitate appropriate channeling of new drugs into brain cancer clinical trials. Areas covered in this review: Barriers to successful drug activity against brain cancer and issues affecting intratumoral drug concentrations are reviewed. The use of the microdialysis technique for extracellular fluid (ECF) sampling and its application to drug distribution studies in brain are reviewed using published literature from 1995 to the present. The benefits and limitations of microdialysis for performing neuorpharmacokinetic (nPK) and neuropharmacodynamic (nPD) studies are discussed. What the reader will gain: The reader will gain an appreciation of the challenges involved in identifying agents likely to have efficacy in brain cancer, an understanding of the general principles of microdialysis, and the power and limitations of using this technique in early drug development for brain cancer therapies. Take home message: A major factor preventing efficacy of anti-brain cancer drugs is limited access to tumor. Intracerebral microdialysis allows sampling of drug in the brain ECF. The resulting nPK/nPD data can aid in the rational selection of drugs for investigation in brain tumor clinical trials. PMID:20969450

    Although palliative care has been developed and implemented as care for cancer pain, it is holistic care for suffering that includes physical, psychosocial and spiritual pain of life-threatening illness. It turned out that non-cancer patients in the end-stage are also suffering from various pain that should be treated as cancer patients. Trajectories of illness in non-cancer patients are with more gradual decline than those of cancer patients with steady progression and it is often difficult to make decision about end-of-life. The purpose of advance care planning was originally to help describe legal documents. This process is proved to contribute to improving QOL of patients and their families to discuss preference, hope, economic problems, spiritual question as well as medical treatment In Japan guideline of decision making process in end-of-life stage has been established. A program of communication training in end-of-life discussion has been made. Under current situation some comments on the role of anesthesiologists are also mentioned. PMID:27097506

    One of the hallmark features of glioblastoma multiforme (GBM), the most common adult primary brain tumor with a very dismal prognosis, is the accumulation of CD4+CD25+Foxp3+ regulatory T cells (Tregs). Regulatory T cells (Tregs) segregate into two primary categories: thymus-derived natural Tregs (nTregs) that develop from the interaction between immature T cells and thymic epithelial stromal cells, and inducible Tregs (iTregs) that arise from the conversion of CD4+FoxP3− T cells into FoxP3 expressing cells. Normally, these Treg subsets complement one another’s actions by maintaining tolerance of self-antigens, thereby suppressing autoimmunity, while also enabling effective immune responses toward non-self-antigens, thus promoting infectious protection. However, Tregs have also been shown to be associated with the promotion of pathological outcomes, including cancer. In the setting of GBM, nTregs appear to be primary players that contribute to immunotherapeutic failure, ultimately leading to tumor progression. Several attempts have been made to therapeutically target these cells with variable levels of success. The blood brain barrier-crossing chemotherapeutics, temozolomide, and cyclophosphamide (CTX), vaccination against the Treg transcriptional regulator, FoxP3, as well as mAbs against Treg-associated cell surface molecules CD25, CTLA-4, and GITR are all different therapeutic approaches under investigation. Contributing to the poor success of past approaches is the expression of indoleamine 2,3-dioxygenase 1 (IDO), a tryptophan catabolizing enzyme overexpressed in GBM, and critically involved in regulating tumor-infiltrating Treg levels. Herein, we review the current literature on Tregs in brain cancer, providing a detailed phenotype, causative mechanisms involved in their pathogenesis, and strategies that have been used to target this population, therapeutically.

    Common and deadly complications of non-small cell lung cancer (NSCLC) are brain metastases (BM). BM portends a poorer prognosis with limited effective treatment options and current management strategies present several challenges from iatrogenic complications of supportive medications, optimal delivery of drug across the blood-brain barrier, and preservation of neurocognitive function. Long term side effects and survivorship issues have become more evident in the era of targeted therapy where a systemic disease is much better controlled. Targeted therapies and immunotherapy are beginning to provide improvements in responses and survival rates. With further advancements and experience, our knowledge in this era of precision medicine will likely lead to strides in improving the quality of life and overall survival of patients with BM from NSCLC. In this review, we present the most recent updates in treatment of BM in NSCLC in regards to targeted and immunotherapy. PMID:26709658

    Classification of pediatric brain tumors with unusual histologic and clinical features may be a diagnostic challenge to the pathologist. We present a case of a 12-year-old girl with a primary intracranial tumor. The tumor classification was not certain initially, and the site of origin and clinical behavior were unusual. Genomic characterization of the tumor using a Clinical Laboratory Improvement Amendment (CLIA)-certified next-generation sequencing assay assisted in the diagnosis and translated into patient benefit, albeit transient. Our case argues that next generation sequencing may play a role in the pathological classification of pediatric brain cancers and guiding targeted therapy, supporting additional studies of genetically targeted therapeutics.

    Listeria monocytogenes is an uncommon cause of illness in the general population. Meningoencephalitis is the most common central nervous system (CNS) manifestation of listeriosis. However, brain abscess represents 1-10% of all CNS listeriosis. To our knowledge, L. monocytogenes brain abscess in multiple myeloma patients has not been previously reported. Thus we report a 58-year-old male patient with multiple myeloma who developed a brain abscess due to L. monocytogenes. Due to a history of penicillin allergy, he was treated with intravenous trimethoprim/sulfamoxazole (TMP-SMX) for a total of 12 weeks, and gentamicin for the first two weeks, followed by oral therapy of TMP-SMX for a total of nine months. He is alive six and a half years after the diagnosis of myeloma with occasional brief seizures despite being on two anticonvulsants. PMID:21252468

    Aim Polysubstance users represent the largest group of patients seeking treatment at addiction and rehabilitation clinics in Turkey. There is little knowledge about the structural brain abnormalities seen in polysubstance users. This study was conducted to examine the structural brain differences between polysubstance use disorder patients and healthy control subjects using voxel-based morphometry. Methods Forty-six male polysubstance use disorder patients in the early abstinence period and 30 healthy male controls underwent structural magnetic resonance imaging scans. Voxel-based morphometry analysis was performed to examine gray matter (GM) abnormality differences. Results Polysubstance use disorder patients displayed significantly smaller GM volume in the thalamus, temporal pole, superior frontal gyrus, cerebellum, gyrus rectus, occipital lobe, anterior cingulate cortex, superior temporal gyrus, and postcentral gyrus. Conclusion A widespread and smaller GM volume has been found at different regions of the frontal, temporal, occipital, and parietal lobes, cerebellum, and anterior cingulate cortex in polysubstance users.

    Patients with acute lung injury or acute respiratory distress syndrome (ARDS) admitted to the ICU present neuropsychological alterations, which in most cases extend beyond the acute phase and have an important adverse effect upon quality of life. The aim of this review is to deepen in the analysis of the complex interaction between lung and brain in critically ill patients subjected to mechanical ventilation. This update first describes the neuropsychological alterations occurring both during the acute phase of ICU stay and at discharge, followed by an analysis of lung-brain interactions during mechanical ventilation, and finally explores the etiology and mechanisms leading to the neurological disorders observed in these patients. The management of critical patients requires an integral approach focused on minimizing the deleterious effects over the short, middle or long term. PMID:23260265

    Purpose We evaluated the uptake of angiopep-2 paclitaxel conjugate, ANG1005, into brain and brain metastases of breast cancer in rodents. Most anticancer drugs show poor delivery to brain tumors due to limited transport across the blood-brain barrier (BBB). To overcome this, a 19-amino acid peptide (angiopep-2) was developed that binds to low density lipoprotein receptor-related protein (LRP) receptors at the BBB and has the potential to deliver drugs to brain by receptor-mediated transport. Methods The transfer coefficient (Kin) for brain influx was measured by in situ rat brain perfusion. Drug distribution was determined at 30 min after i.v. injection in mice bearing intracerebral MDA-MB-231BR metastases of breast cancer. Results The BBB Kin for 125I-ANG1005 uptake (7.3 ± 0.2 × 10−3 mL/s/g) exceeded that for 3H-paclitaxel (8.5 ± 0.5 × 10−5) by 86 fold. Over 70% of 125I-ANG1005 tracer stayed in brain after capillary depletion or vascular washout. Brain 125I-ANG1005 uptake was reduced by unlabeled angiopep-2 vector and by LRP ligands, consistent with receptor transport. In vivo uptake of 125I-ANG1005 into vascularly corrected brain and brain metastases exceeded that of 14C-paclitaxel by 4–54 fold. Conclusions The results demonstrate that ANG1005 shows significantly improved delivery to brain and brain metastases of breast cancer compared to free paclitaxel. PMID:19774344

    Brain metastasis from esophageal carcinoma (BMEC) is very rare, but its incidence has increased in the United States, Japan, China and other counties. Reports on BMEC have largely been focused on examining whether adjuvant therapy for esophageal cancer influences the survival duration of BMEC patients and on the imaging characteristics of BMEC determined using new medical equipment. The difference between different pathological types of esophageal cancer, especially adenocarcinoma and squamous cell carcinoma, is one important factor used to assess the influence of BMEC. Adjuvant therapy, including radiotherapy and chemotherapy, for esophageal cancer with different characteristics in different countries may affect BMEC treatment outcomes. The degree of popularization of advanced medical equipment is a major concern related to the prevalence of BMEC. Furthermore, targeted BMEC treatment is under development in developed countries. In this article, we reviewed the debate surrounding BMEC and analyzed BMEC studies from different perspectives. PMID:26019444

    Crizotinib achieves excellent systemic control in anaplastic lymphoma kinase-rearranged (ALK+) non-small cell lung cancer (NSCLC); however, central nervous system (CNS) metastases frequently occur as an early event. Whole brain irradiation, the standard treatment, results in neurocognitive impairment. We present a case series of three ALK+ NSCLC patients with progressing CNS metastases who were treated with pulse-dose crizotinib followed by ceritinib. Three ALK+ NSCLC patients treated between 2011 and 2014 (two males, two never smokers, age range 20-54years, all echinoderm microtubule-associated protein-like 4/ALK rearrangement), were diagnosed with progressing cerebral disease while receiving crizotinib. Clinico-pathological characteristics, treatments, and outcomes were analyzed. In two patients the progression was limited to the CNS, and radiological evidence of leptomeningeal spread was present in one patient. Sequential use of crizotinib 500mg administered once daily (pulse-dose) followed by ceritinib on progression achieved control of the disease in the CNS for over 18 months and over 7 months in Patient 1 and Patient 2, respectively. This strategy provided durable CNS control after whole-brain radiotherapy failure in Patient 1, and allowed the whole-brain radiotherapy to be deferred in Patient 2. Limited CNS progression was documented in Patient 3 while he was on standard-dose/pulse-dose crizotinib for 15months; durable (over 7 months) complete remission was achieved with stereotactic radiotherapy and ceritinib. Manipulating the crizotinib schedule in ALK+ NSCLC patients with CNS metastases and using a novel ALK-inhibitor at the time of further progression may provide durable CNS control and allow brain radiotherapy to be deferred.

    OBJECTIVE: To assess family physicians' and specialists' involvement in cancer follow-up care and how this involvement is perceived by cancer patients. DESIGN: Self-administered survey. SETTING: A health region in New Brunswick. PARTICIPANTS: A nonprobability cluster sample of 183 participants. MAIN OUTCOME MEASURES: Patients' perceptions of cancer follow-up care. RESULTS: More than a third of participants (36%) were not sure which physician was in charge of their cancer follow-up care. As part of follow-up care, 80% of participants wanted counseling from their family physicians, but only 20% received it. About a third of participants (32%) were not satisfied with the follow-up care provided by their family physicians. In contrast, only 18% of participants were dissatisfied with the follow-up care provided by specialists. Older participants were more satisfied with cancer follow-up care than younger participants. CONCLUSION: Cancer follow-up care is increasingly becoming part of family physicians' practices. Family physicians need to develop an approach that addresses patients' needs, particularly in the area of emotional support. PMID:12901486

    integration of these services into national cancer control plans; the need for public education to reduce the fear and stigma associated with cancer so that patients are better able to make informed decisions regarding follow-up care and treatment; and the need to recognize the challenges and needs of survivors, their increasing number, the necessity to integrate survivorship into cancer control plans and the economic and societal value of functional survival after cancer. Discussions highlighted that coordinated care and treatment for cancer patients is both a ' systems'challenge and solution, requiring the consideration of patient and family circumstances, societal values and priorities, the functioning of the health system (access, capacity, resources, etc.) and the importance assigned to health and illness management within public policy.

    Cancer presents itself in numerous ways, adding to the complexity of any pain syndrome with which it is associated. Neuropathic pain, unlike many other pain syndromes, is difficult to treat even in the absence of cancer. The combination results in a heterogeneous group of patients with a complex set of symptoms. This makes the assessment of pain, classification of syndromes, and clinical study a challenge. If the disease is nonprogressive, general principles of care are essentially the same as in those without cancer. In patients with progressive disease and more refractory painful conditions, spinal anesthetic and neurosurgical therapies must often be considered. Under such circumstances, caregivers are forced to carefully balance uncertain benefits and risks, often without the luxury of time. More careful observation and controlled trials in these patients help facilitate this challenging process. PMID:9767067

    Patients with implanted neuromodulation devices present potential challenges for radiation therapy treatment planning and delivery. Although guidelines exist regarding the irradiation of cardiac pacemakers and defibrillators, fewer data and less clinical experience exist regarding the effects of radiation therapy on less frequently used devices, such as deep brain stimulators. A 79-year-old woman with a history of coarse tremors effectively managed with deep brain stimulation presented with multiple intracranial metastases from a newly diagnosed lung cancer and was referred for whole-brain radiation therapy. She was treated with a German helmet technique to a total dose of 30 Gy in 10 fractions using 6 MV photons via opposed lateral fields with the neurostimulator turned off prior to delivery of each fraction. The patient tolerated the treatment well with no acute complications and no apparent change in the functionality of her neurostimulator device or effect on her underlying neuromuscular disorder. This represents the first reported case of the safe delivery of whole-brain radiation therapy in a patient with an implanted neurostimulator device. In cases such as this, neurosurgeons and radiation oncologists should have discussions with patients about the risks of brain injury, device malfunction or failure of the device, and plans for rigorous testing of the device before and after radiation therapy.

    Abstract Patients with head and neck cancer are treated through surgery, radiotherapy (RT), and chemotherapy (CT). Carotid artery damage and neurotoxicity were previously observed in these patients. This study estimated the dementia risk associated with different treatment modalities in a head and neck cancer population with long-term follow-up. Taiwan's National Health Insurance claims database and a cancer registry database from the Collaboration Center of Health Information Application were linked for the present analysis. Patients with head and neck cancer, treated from January 1, 2002 to December 31, 2010, were included in the study. The follow-up duration was the period from the index date to December 31, 2012. Inclusion criteria were head and neck cancer; an age >20 years; and having undergone surgery, CT, concurrent CT, or surgery with adjuvant treatment. Exclusion criteria were another cancer diagnosed before the head and neck cancer, death or being diagnosed with dementia within 2 years after the treatment of the head and neck cancer, stroke before the index date, distant metastasis, in situ carcinoma, sarcoma, head and neck cancer recurrence, an unknown sex, and an age <20 years. In total, 20,135 patients were included. In patient groups that underwent surgery alone, surgery and adjuvant chemoradiotherapy, and chemoradiotherapy alone, the dementia incidence per 1000 person-years was 1.44, 1.04, and 1.98, respectively. The crude hazard ratio (HR) of dementia was 1.84 (95% confidence interval [CI] 1.21–2.81) in the RT with or without CT group. After adjustment for age, sex, clinical stage, and comorbidity, the HR was 1.92 (95% CI 1.14–3.24). Examining the dementia risk in patients who received different treatment modalities according to the Cox proportional-hazard model revealed that an age >65 years and having undergone RT with or without CT were risk factors (P < 0.001 and P = 0.015; and HRs of 16.5 and 1.92, respectively).

    Purpose of review Pneumonia is the leading cause of death among neutropenic cancer patients, particularly those with acute leukemia. Even with empiric therapy, case fatality rates of neutropenic pneumonias remain unacceptably high. However, recent advances in the management of neutropenic pneumonia offer hope for improved outcomes in the cancer setting. This review summarizes recent literature regarding the clinical presentation, microbiologic trends, diagnostic advances and therapeutic recommendations for cancer-related neutropenic pneumonia. Recent findings While neutropenic patients acquire pathogens both in community or nosocomial settings, patients’ obligate healthcare exposures result in the frequent identification of multidrug resistant bacterial organisms on conventional culture-based assessment of respiratory secretions. Modern molecular techniques, including expanded use of galactomannan testing, have further facilitated identification of fungal pathogens, allowing for aggressive interventions that appear to improve patient outcomes. Multiple interested societies have issued updated guidelines for antibiotic therapy of suspected neutropenic pneumonia. The benefit of antibiotic medications may be further enhanced by agents that promote host responses to infection. Summary Neutropenic cancer patients have numerous potential causes for pulmonary infiltrates and clinical deterioration, with lower respiratory tract infections among the most deadly. Early clinical suspicion, diagnosis and intervention for neutropenic pneumonia provide cancer patients’ best hope for survival. PMID:25784246

    We present the first X-PEEM spectromicroscopy semi-quantitative data, acquired on Gd in glioblastoma cell cultures from human brain cancer. The cells were treated with a Gd compound for the optimization of GdNCT (Gadolinium Neutron Capture Therapy). We analyzed the kinetics of Gd uptake as a function of exposure time, and verified that a quantitative analytical technique gives the same results as our MEPHISTO X-PEEM, demonstrating the feasibility of semi-quantitative spectromicroscopy.

    Stereotactic radiosurgery (SRS) has been increasingly employed as an alternative to whole brain radiation therapy in patients with brain metastases, with the aim to reduce its potential toxicity. We have evaluated clinical outcomes of SRS as initial treatment for brain metastases in patients 70 years and older. Between November 2007 and October 2011, 102 patients of 70 years and older with 1-4 metastases were treated with SRS. The primary end point of the study was overall survival. Secondary end points were local control and distant failure rates, cause of death, performance measurements, and toxicity of treatment. At a median follow-up of 11.0 months (range 1-48 months), median survival and median time to distant failure were 13.2 and 10 months, respectively. The 1- and 2-year survival rates were 63 and 28 %, and respective distant failure rates were 54 and 78 %. Forty-five patients succumbed to their extracranial disease and 14 patients died of progressive intracranial disease. Nine patients recurred locally after SRS. The 1- and 2-year local control rates were 90 and 84 %, respectively. Evaluation of neurocognitive function using the Mini-Mental State Examination (MMSE) showed no significant neurocognitive decline after SRS. MMSE score improved in 15 % of patients, worsened in 12 % of patients, and remained stable in the others. Severe neurological complications were reported in 7 (7 %) patients, requiring surgery or medical treatment. Initial treatment with SRS with close monitoring may represent a relatively safe treatment strategy associated with survival benefit, with outcomes similar to those reported in historical series of SRS for younger patients.

    2016-02-01

    Cancer patients have a 2-7 fold increased risk of venous thromboembolism compared with the general population and, since 1990, this is associated with significant morbidity and mortality. This review summarizes the current knowledge on venous thromboembolism and cancer. Notably, the risk of venous thromboembolism varies depending on the type and stage of cancer. For instance, pancreatic and brain cancer patients have a higher risk of venous thromboembolism than breast and prostate cancer patients. Moreover, patients with metastatic disease have a higher risk than those with localized tumors. Tumor-derived procoagulant factors, cytokines and growth factors may directly and indirectly enhance venous thromboembolism. Chemotherapy produces ~6,5 fold increase in venous thromboembolism incidence in cancer patients compared to the general population. Prevention of this complication is challenging. The authors review the development of guidelines concerning venous thromboembolism prevention in hospitalized and also in ambulatory cancer patients treated with chemotherapy. Current guidelines recommend the use of low-molecular-weight heparin. Understanding the underlying mechanisms may allow the development of new therapies to safely prevent venous thromboembolism in cancer patients. PMID:27120721

    Approximately 6% of women with breast cancer are diagnosed before the age of 40. Young age is an independent predictor of adverse outcome and most young breast cancer patients receive systemic treatment with chemotherapy, hormonal therapy or both. The loss or impairment of fertility is a potential side effect of antineoplastic treatments. Due to the rising trend to delaying pregnancy in life, an increasing proportion of young cancer patients who are yet to have a pregnancy will face the problem of iatrogenic menopause in the future. The incidence of anticancer-treatment-related ovarian failure depends on the type of chemotherapy regimen administered, the use of tamoxifen and the age of patients. It rises with increasing age, in the range of 22-61% and 61-97% in women aged <40 years and >40 years respectively. Although there is a clear trend to increasing incidence of ovarian failure with the rise in aging, there may be a small proportion of patients who became amenorrhoeic despite the very young age, thus indicating that also individual factors still unknown may affect the probability of treatment-related ovarian failure. A prompt referral of patients to reproductive counseling and a multidisciplinary team including Oncology and Reproductive Units are essential to face the management of fertility issues in cancer patients. Fertility counseling should include a detailed description of all the available techniques to preserve fertility. The main available fertility preservation techniques, standard and experimental, for young breast cancer patients include: temporary ovarian suppression during chemotherapy with gonadotropin-releasing hormone analogues, embryo cryopreservation, cryopreservation of oocytes and cryopreservation of ovarian tissue. Research efforts are still necessary to improve the efficacy and safety of the available fertility preservation strategies as well as an efficient collaboration between oncologists and gynecologists is necessary to improve

    Renal cancer occurs more frequently in renal transplanted patients than in the general population, affecting native kidneys in 90% of cases and the graft in 10 %. In addition to general risk factors, malignancy susceptibility may be influenced by immunosuppressive therapy, the use of calcineurin inhibitors (CNI) as compared with mammalian target of rapamycin inhibitors, and the length of dialysis treatment. Acquired cystic kidney disease may increase the risk for renal cancer after transplantation, while autosomal dominant polycystic kidney disease does not seem to predispose to cancer development. Annual ultrasound evaluation seems appropriate in patients with congenital or acquired cystic disease or even a single cyst in native kidneys, and every 2 years in patients older than 60 years if they were on dialysis for more than 5 years before transplantation. Immunosuppression should be lowered in patients who develop renal cancer, by reduction or withdrawal of CNI. Although more evidence is still needed, it seems reasonable to shift patients from CNI to everolimus or sirolimus if not already treated with one of these drugs, with due caution in subjects with chronic allograft nephropathy.

    Anandavadivelan, Poorna; Lagergren, Pernilla

    2016-03-01

    Oesophageal cancer is a debilitating disease with a poor prognosis, and weight loss owing to malnutrition prevails in the majority of patients. Cachexia, a multifactorial syndrome characterized by the loss of fat and skeletal muscle mass and systemic inflammation arising from complex host-tumour interactions is a major contributor to malnutrition, which is a determinant of tolerance to treatment and survival. In patients with oesophageal cancer, cachexia is further compounded by eating difficulties owing to the stage and location of the tumour, and the effects of neoadjuvant therapy. Treatment with curative intent involves exceptionally extensive and invasive surgery, and the subsequent anatomical changes often lead to eating difficulties and severe postoperative malnutrition. Thus, screening for cachexia by means of percentage weight loss and BMI during the cancer trajectory and survivorship periods is imperative. Additionally, markers of inflammation (such as C-reactive protein), dysphagia and appetite loss should be assessed at diagnosis. Routine assessments of body composition are also necessary in patients with oesophageal cancer to enable assessment of skeletal muscle loss, which might be masked by sarcopenic obesity in these patients. A need exists for clinical trials examining the effectiveness of therapeutic and physical-activity-based interventions in mitigating muscle loss and counteracting cachexia in these patients.

    In recent years there have been major advances in the treatment of breast cancer. However, taking the prescribed medication for a sufficient period of time is crucial to the success of any therapy. Thus far, no database-based studies have been published in German-speaking countries empirically examining the influence of the physician on the compliance of patients. The aim of this study is to investigate, quantify, and critically discuss the effect treating physicians have on the compliance of their breast cancer patients. Patients with a confirmed breast cancer diagnosis who started therapy (tamoxifen or aromatase inhibitors) between January 2001 and December 2011 were selected from the representative IMS Disease Analyzer database and analyzed with regard to their compliance. Practices were grouped into two categories concerning the compliance of all treated patients. A regression model showed that a breast cancer patient who is treated in a practice with a trend toward poor compliance has a nearly 60% higher risk for treatment discontinuation than would be the case in a practice with good compliance. It shows how important it is to motivate physicians to strive toward good compliance rates. PMID:24454275

    A second course of whole brain radiation therapy (WBRT) has been employed in selected patients with progressive brain metastases providing favorable symptomatic palliation with acceptable toxicity, although its efficacy and safety remain matter of debate. In the present study we have evaluated the outcomes in patients with progressive intracranial disease treated with WBRT reirradiation and concurrent temozolomide between October 2010 and May 2013. Data were obtained from a prospectively maintained database including patients with brain tumors treated with radiotherapy at Sant'Andrea Hospital. We identified 27 patients (10 males and 17 females) with a median age of 54 years who received WBRT reirradiation at a dose of 25 Gy in ten fractions plus concomitant daily temozolomide administered orally at a dose of 75 mg/m(2). At the time of repeat WBRT all patients had a KPS ≥ 60. The primary disease sites were lung (n = 18) and breast (n = 9). The median overall survival after the second course of WBRT was 6.2 months and the median time to progression was 5.5 months. Eight patients experienced complete resolution of symptoms, 9 patients had a significant improvement, and 6 patients had no change in their neurologic function. Four patients had further deterioration after reirradiation. Overall, 85 % of patients improved or maintained their neurologic status. No severe acute toxicity during or after the second course of WBRT reirradiation was observed. On multivariate analysis with the Cox proportional hazards model, stable or absent extracranial metastases (p = 0.005) and response to treatment (p = 0.01) were independent favorable prognostic factors for survival. The median and 12-month survival rates were 12 months and 50 % in patients with stable or absent extracranial disease and 4.6 months and 7 % in those with progressive extracranial disease (p = 0.001). In conclusion, in the respect to the small number of treated patients, repeat WBRT plus concomitant

    Conflicting data exist on the prognosis of hereditary colorectal cancer. HNPCC patients, in particular, are often reported to have a better survival. We examined 2,340 colorectal-cancer patients treated in our Institution: 144 HNPCC patients (Amsterdam Criteria), 161 FAP patients and 2,035 patients with sporadic cancer. Data on hereditary-cancer patients treated between 1980 and 1995 was collected in a registry. The 2,035 sporadic colorectal-cancer patients (controls) included all new cases treated in the Department of Gastrointestinal-Tract Surgery during the same period. Observed survival was estimated using the Kaplan-Meier method. Cumulative survival probability was estimated at 5 years within each group and stratified by various clinical and pathological variables. The age distribution at diagnosis of sporadic patients was significantly higher than that of FAP and HNPCC patients (median 60 years vs. 43 and 49 years; p < 0.0001). In the HNPCC group, 40% had a right cancer location, vs. 14% in the FAP group and 13% in the sporadic-cancer group. In the sporadic group, 51% were early-stage cancers (Dukes A or B) vs. 48.4% and 52.1% in the FAP and HNPCC groups respectively. In the HNPCC, FAP and sporadic-cancer groups, the 5-year cumulative survival rate was 56.9%, 54.4% and 50.6% respectively. Survival analysis by the Cox proportional-hazards method revealed no substantial survival advantage for HNPCC and FAP patients compared with the sporadic group, after adjustment for age, gender, stage and tumor location. The hazard ratio for HNPCC was 1.01 (95% CI 0.72-1.39) and 1.27 (95% CI 0.95-1.7) for FAP patients compared with the sporadic-colorectal-cancer group. PMID:9935197

    Glioblastoma multiforme (GBM) is the most common primary brain cancer in adults. Despite significant advances in treatment and intensive research, the prognosis for patients with GBM remains poor. Therapeutic challenges for GBM include its invasive nature, the proximity of the tumor to vital brain structures often preventing total resection, and the resistance of recurrent GBM to conventional radiotherapy and chemotherapy. Gene therapy has been proposed as a useful adjuvant for GBM, to be used in conjunction with current treatment. Work from our laboratory has shown that combination of conditional cytotoxic with immunotherapeutic approaches for the treatment of GBM elicits regression of large intracranial tumor masses and anti-tumor immunological memory in syngeneic rodent models of GBM. In this review we examined the currently available animal models for GBM, including rodent transplantable models, endogenous rodent tumor models and spontaneous GBM in dogs. We discuss non-invasive surrogate end points to assess tumor progression and therapeutic efficacy, such as behavioral tests and circulating biomarkers. Growing preclinical and clinical data contradict the old dogma that cytotoxic anti-cancer therapy would lead to an immune-suppression that would impair the ability of the immune system to mount an anti-tumor response. The implications of the findings reviewed indicate that combination of cytotoxic therapy with immunotherapy will lead to synergistic antitumor efficacy with reduced neurotoxicity and supports the clinical implementation of combined cytotoxic-immunotherapeutic strategies for the treatment of patients with GBM.

    Purpose: To review the impact of anemia/tumor hypoxemia on the quality of life and survival in cancer patients, and to assess the problems associated with the correction of this difficulty. Methods: MEDLINE searches were performed to find relevant literature regarding anemia and/or tumor hypoxia in cancer patients. Articles were evaluated in order to assess the epidemiology, adverse patient effects, anemia correction guidelines, and mechanisms of hypoxia-induced cancer cell growth and/or therapeutic resistance. Past and current clinical studies of radiosensitization via tumor oxygenation/hypoxic cell sensitization were reviewed. All clinical studies using multi-variate analysis were analyzed to show whether or not anemia and/or tumor hypoxemia affected tumor control and patient survival. Articles dealing with the correction of anemia via transfusion and/or erythropoietin were reviewed in order to show the impact of the rectification on the quality of life and survival of cancer patients. Results: Approximately 40-64% of patients presenting for cancer therapy are anemic. The rate of anemia rises with the use of chemotherapy, radiotherapy, and hormonal therapy for prostate cancer. Anemia is associated with reductions both in quality of life and survival. Tumor hypoxemia has been hypothesized to lead to tumor growth and resistance to therapy because it leads to angiogenesis, genetic mutations, resistance to apoptosis, and a resistance to free radicals from chemotherapy and radiotherapy. Nineteen clinical studies of anemia and eight clinical studies of tumor hypoxemia were found that used multi-variate analysis to determine the effect of these conditions on the local control and/or survival of cancer patients. Despite differing definitions of anemia and hypoxemia, all studies have shown a correlation between low hemoglobin levels and/or higher amounts of tumor hypoxia with poorer prognosis.

    The purpose of this study is to identify the needs of brain tumor patients and their caregivers to provide improved health services to these populations. Two different questionnaires were designed for patients and caregivers. Both questionnaires contained questions pertaining to three realms: disease symptoms/treatment, health care provider, daily living/finances. The caregivers' questionnaires contained an additional domain on emotional needs. Each question was evaluated for the degree of importance and satisfaction. Exploratory analyses determined whether baseline characteristics affect responder importance or satisfaction. Also, areas of high agreement/disagreement in satisfaction between the participating patient-caregiver pairs were identified. Questions for which >50% of the patients and caregivers thought were "very important" but >30% were dissatisfied include: understanding the cause of brain tumors, dealing with patients' lower energy, identifying healthful foods and activities for patients, telephone access to health care providers, information on medical insurance coverage, and support from their employer. In the emotional realm, caregivers identified 9 out of 10 items as important but need further improvement. Areas of high disagreement in satisfaction between participating patient-caregiver pairs include: getting help with household chores (P value = 0.006) and finding time for personal needs (P value < 0.001). This study provides insights into areas to improve services for brain tumor patients and their caregivers. The caregivers' highest amount of burden is placed on their emotional needs, emphasizing the importance of providing appropriate medical and psychosocial support for caregivers to cope with emotional difficulties they face during the patients' treatment process.

    The use of complementary and alternative medicine (CAM) is increasing. CAM includes mind-body interventions, biologically based therapies, energy therapies, and body-based methods. Primary brain tumors arise within the brain and have a poor prognosis when malignant. Even patients with benign tumors suffer neurologic and systemic symptoms as a result of the tumor or its treatment. CAM is used by 30% of brain tumor patients, who often do not report its use to their physician. Herbal medicines may affect the metabolism of prescribed medications or produce adverse effects that may be attributed to other causes. In patients with systemic cancer, mind-body modalities such as meditation and relaxation therapy have been shown to be helpful in reducing anxiety and pain; acupuncture and hypnotherapy may also reduce both pain and nausea. Recent preclinical studies have reported that ginseng, Scutellaria baicalensis, and Angelica sinensis may promote apoptosis of tumor cells or exercise antiangiogenic effects. Further studies are needed to evaluate the impact of CAM on symptom control or tumor growth in this vulnerable patient population. PMID:18541122

    The aim of this study was to investigate whether statin utilization is associated with brain cancer risk.A population-based case-control study was conducted using nationally representative claims data from the National Health Insurance Bureau in Taiwan. Cases included all patients 50 years and older who received an index diagnosis of brain cancer between 2004 and 2011. Our controls were matched by age, sex, and index date. We estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) using multiple logistic regression.We examined 213 brain cancer cases and 852 controls. The unadjusted ORs for any statin prescription was 0.77 (95% CI = 0.50-1.18) and the adjusted OR was 0.59 (95% CI = 0.37-0.96). Compared with no use of statins, the adjusted ORs were 0.68 (95% CI = 0.38-1.24) for the group having been prescribed with statins with cumulative defined daily dose (DDD) below 144.67 DDDs and 0.50 (95% CI = 0.28-0.97) for the group with the cumulative statin use of 144.67 DDDs or more.The results of this study suggest that statins may reduce the risk of brain cancer.

    Radiation treatment for cancer requires patients to receive frequent administrations and attend the treatment facility on a daily basis for several weeks. Travelling for radiation treatment has the potential to add to the distress an individual may be feeling. This study utilized in-depth interviews to capture 118 patients' perspectives about travelling for cancer treatment. Four themes emerged during the analysis of the data: (1) waiting was the most difficult part of the experience; (2) the idea of travelling for treatment was distressing; (3) travelling for treatment was tiring and posed difficulties for patients; and (4) being away from home had both benefits and drawbacks. Given the inevitability of travelling for radiation treatment, and the issues that arises for patients, supportive strategies need to be designed and implemented. PMID:14502591

    Infertility can arise as a consequence of treatment of oncological conditions. The parallel and continued improvement in both the management of oncology and fertility cases in recent times has brought to the forefront the potential for fertility preservation in patients being treated for cancer. Many survivors will maintain their reproductive potential after the successful completion of treatment for cancer. However total body irradiation, radiation to the gonads, and certain high dose chemotherapy regimens can place women at risk for acute ovarian failure or premature menopause and men at risk for temporary or permanent azoospermia. Providing information about risk of infertility and possible interventions to maintain reproductive potential are critical for the adolescent and young adult population at the time of diagnosis. There are established means of preserving fertility before cancer treatment; specifically, sperm cryopreservation for men and in vitro fertilization and embryo cryopreservation for women. Several innovative techniques are being actively investigated, including oocyte and ovarian follicle cryopreservation, ovarian tissue transplantation, and in vitro follicle maturation, which may expand the number of fertility preservation choices for young cancer patients. Fertility preservation may also require some modification of cancer therapy; thus, patients' wishes regarding future fertility and available fertility preservation alternatives should be discussed before initiation of therapy.

    Vitamin D is a hormone that is synthesised in the skin in the presence of sunlight. Sufficient vitamin D levels are important-not only for a healthy skeleton-but also for a healthy immune system. Many patients with cancer have insufficient vitamin D levels, and low vitamin D levels are associated with increased 'all-cause mortality' and especially mortality due to cancer. Low vitamin D levels have also been associated with increased risk of infections, increased pain, depressive disorders and impaired quality of life. We review the role of vitamin D in the immune system, in relation to cancer disease, pain and depression. We have recently performed an observational study in 100 patients with palliative cancer in Sweden. The main result was that low vitamin D levels were associated with higher opioid dose, that is, more pain. We also describe a case report where vitamin D supplementation resulted in radically decreased opioid dose, less pain and better well-being. Vitamin D supplementation is not connected with any adverse side effects and is easy to administrate. Thus, we hypothesise that vitamin D-supplementation to patients with palliative cancer might be beneficial and could improve their well-being, decrease pain and reduce susceptibility to infections. However, more clinical studies in this field are needed before firm conclusions can be drawn. PMID:27084421

    Evidence shows that continued smoking by cancer patients leads to adverse treatment outcomes and affects survival. Smoking diminishes treatment effectiveness, exacerbates side effects, and increases the risk of developing additional complications. Patients who continue to smoke also have a higher risk of developing a second primary cancer or experiencing a cancer recurrence, both of which ultimately contribute to poorer quality of life and poorer survival. Here, we present a snapshot of smoking behaviours of current cancer patients compared with the non-cancer patient population in Canada. Minimal differences in smoking behaviours were noted between current cancer patients and the rest of the population. Based on 2011-2014 data from the Canadian Community Health Survey, 1 in 5 current cancer patients (20.1%) reported daily or occasional smoking. That estimate is comparable to findings in the surveyed non-cancer patient population, of whom 19.3% reported smoking daily or occasionally. Slightly more male cancer patients than female cancer patients identified as current smokers. A similar distribution was observed in the non-cancer patient population. There is an urgent need across Canada to better support cancer patients in quitting smoking. As a result, the quality of patient care will improve, as will cancer treatment and survival outcomes, and quality of life for these patients. PMID:27330349

    Brain metastases (BM) are frequently diagnosed in metastatic Her2-positive breast cancer. Local treatment remains the standard of care but lapatinib plus capecitabine was recently established as systemic therapy option. Due to a disruption of the blood-brain/tumour-barrier at metastatic sites, even large molecules may penetrate into the central nervous system (CNS). Here, we report on the activity of T-DM1 in Her2-positive breast cancer BM. T-DM1 was administered at a dose of 3.6 mg once every 3 weeks as primary systemic therapy for BM or upon documented CNS progression after initial local treatment. Thus, this study allowed for the appraisal of T-DM1 activity in BM. Restaging was conducted every 12 weeks with MRI or whenever symptoms of disease progression occurred. Ten patients were included; in two asymptomatic subjects, T-DM1 was administered as primary therapy, while eight had progressive BM. All patients had received prior treatment with trastuzumab, six had already received lapatinib, and three pertuzumab as well. Three patients had partial remission of BM, and two patient had stable disease lasting for ≥6 months; two further patients had stable disease for <6 months while three progressed despite treatment. At 8.5 months median follow-up, intracranial PFS was 5 months, and median OS from initiation of T-DM1 was not reached. Local treatment of BM remains the standard of care; lapatinib plus capecitabine is currently the best established systemic therapy option. Still, T-DM1 apparently offers relevant clinical activity in BM and further investigation is warranted. PMID:26303828

    Breast cancer is a disease associated with aging, with almost one-half of all new breast cancer cases diagnosed annually in the United States occurring in women age 65 and older. Recent data suggest that although breast cancer outcomes in younger women have shown substantial improvement as a result of advances in treatment and screening, the benefits in older women have been less pronounced. Although older adults have been under-represented on cancer clinical trials there is an emerging body of literature to help guide treatment decisions. For early stage breast cancer, the discussion regarding treatment options involves balancing the reduction in risk of recurrence gained by specific therapies with the potential for increased treatment-related toxicity potentially exacerbated by physiological decline or comorbidities that often co-exist in the older population. A key component of care of the older adult is the recognition that chronologic age alone cannot guide the management of an older individual with breast cancer; rather, treatment decisions must also take into account an individual’s functional status, estimated life expectancy, the risks and benefits of the therapy, potential barriers to treatment, and patient preference. This article reviews the available evidence for therapeutic management of early-stage breast cancer in older adults, and highlights data from geriatric oncology literature that provides a basis on which to facilitate evidence-based treatment.

    A 63-year-old woman was suffering from HER2-positive and hormone receptor-negative breast cancer with bone metastasis. She received 16 cycles of paclitaxel(PTX 80mg/m2)plus trastuzumab(TRA 2mg/kg)on a 7-day cycle, and zoledronic acid(ZOL 4mg/body every 28 days), resulting in a near clinical complete response(cCR). Two years later, the patient complained of dizziness and nausea, and magnetic resonance imaging revealed multiple brain metastases. The prior treatments with PTX and TRA were changed to lapatinib(LAP)(orally at 1, 250mg/day every day)and capecitabine(CAP)(orally at 2, 000mg/m2 every day for 2 weeks, followed by a 1-week rest interval as 1 cycle)because of the multiple brain metastases. After 4 cycles of treatment, the number of brain lesions and the tumor sizes were significantly reduced. After 7 cycles, however, magnetic resonance imaging revealed the deterioration of some brain lesions. After whole-brain irradiation(30 Gy in 10 fractions)was added to the treatment, the outcome was near cCR. In conclusion, combination therapy of Lap and Cap may be an effective treatment option for brain metastasis of HER2-positive breast cancer. PMID:23152022

    Background | In Germany, place of death is recorded on death certificates, but is not analyzed further. In consequence, only little is known about the place of death among cancer patients at the population level. The aim of the study was to describe the changes of places of death in cancer patients over a time period of 10 years. Material and methods | This study examined death certificates from 2001 and 2011 of selected regions of Westphalia-Lippe (Germany). Cancer patients were identified on the basis of cause of death. Description of frequencies of place of death and subgroup analyses by tumor entity (ICD-10, C00-C96) were performed. Results | A total of 24 009 death certificates were analyzed (2001: 11,585; 2011: 12,424). Cancer was the underlying or contributory cause of death in 34.0%. For the years 2001 and 2011, respectively, the following distributions of place of death were observed: home, 24.1% vs. 24.7% (p=0.553); hospital, 62.8% vs. 51.4% (p=0.001); palliative care unit, 0.0% vs. 2.2%; hospice, 5.5% vs. 12.5% (p=0.001); nursing home, 7.4% vs. 10.9% (p=0.001); other, 0.1% vs. 0.3% (p=0.063); no data, 0.1% vs. 0.3% (p=0.015). Patients with brain tumours had a higher probability of dying in a hospice (2011: female 23.5%; male 27.7%). A higher risk of death in hospital was observed among cancer patients with an underlying hematological malignancy (2011: female 63.7%; male 68.4%). Conclusion | Cancer patients mainly die in institutions, with hospitals being the most frequent location. Only one in four deaths occurs in the home setting. The trend over time shows a shift in place of death away from hospitals towards hospices, palliative care units, and nursing homes. PMID:27557075

    Chronic severe cancer pain is often not well controlled because both patient and physician have a poor understanding of the nature of the pain and of the actions of various potent analgesics. Physicians often fail to tailor analgesic dosages to the needs of the individual and unnecessarily limit the dosage because they have an ill founded fear that the patient will become addicted. The basis of rational management of cancer pain with drugs is an appropriate analgesic given regularly in doses adequate to suppress pain continuously. This review compares the potent analgesics and identifies and discusses those that have a role in treating chronic cancer pain. It emphasizes the value of morphine sulfate and gives information on starting and individualizing dosages and managing side effects. PMID:2856896

    Background One of the most commonly diagnosed cancers is breast cancer that leads to mortality and morbidity among Iranian women. Behavioural risk factors, such as common lifestyle patterns are often associated with risk of breast cancer incidence. Aim This study aimed to investigate lifestyle of breast cancer patients admitted to Cancer Research Center of Mazandaran University of Medical Sciences. Materials and Methods This descriptive cross-sectional study was conducted using convenient sampling method. Sample size consisted of 150 cancer patients, and data collection tool included a researcher-made questionnaire on dimensions of lifestyle containing four dimensions of self-care, exercise and physical activity, diet and coping with stress. Maximum score in different dimensions, based on 100% of marks earned, was evaluated in three categories of undesirable, relatively desirable and desirable. Data were analysed with SPSS-19 software using descriptive statistics (relative and absolute frequencies, mean and standard deviation). Results In total of 150 women, the mean age of patients was 51.9 ± 1.04 (27-78). The majority of participants were married, housewives, with high school education. Among the four parts of healthy lifestyle, desirable level of physical activity and exercise had the least participants, and in the dimensions of physical activity and exercise, the lowest level related to walking, followed by daily exercise. Most of the participants had undesirable level of self-care and lowest frequency related to mammography after 40-year-old, followed by annual check-up and Pap-smear. With regard to nutrition, most of them were at desirable level. Conclusion The results indicated undesirable levels in two lifestyle dimensions (self-care and physical activity and exercise) in the majority of participants for a year before contracting breast cancer. Primary prevention programs should be implemented with a comprehensive approach, thus, effective strategies are

    The incidence of adult brain cancer was previously shown to be higher in countries where the parasite Toxoplasma gondii is common, suggesting that this brain protozoan could potentially increase the risk of tumor formation. Using countries as replicates has, however, several potential confounding factors, particularly because detection rates vary with country wealth. Using an independent dataset entirely within France, we further establish the significance of the association between T. gondii and brain cancer and find additional demographic resolution. In adult age classes 55 years and older, regional mortality rates due to brain cancer correlated positively with the local seroprevalence of T. gondii. This effect was particularly strong for men. While this novel evidence of a significant statistical association between T. gondii infection and brain cancer does not demonstrate causation, these results suggest that investigations at the scale of the individual are merited.

    The disability of visuospatial attention can lead to poor volitional movement and functional recovery in patients with brain lesions. However, the accurate clinical method to assess visuospatial attention is limited. The frontoparietal network including the posterior parietal cortex and the frontal eye fields has been shown to involve in visuospatial attention. The Attention Network Test provided measures for three different components of visuospatial attention: alerting, orienting and executive control. This study was to probe the deficit and relationship of visuospatial attention using Attention Network Test paradigm in patients with frontoparietal network lesions. During this task, patients responded significantly slower on each cue condition and target type than controls, and showed deficits in the alerting and orienting networks. The efficiency of resolving conflict was decreased in patients with frontal lesions whereas this was increased in patients with parietal lesions. These findings suggest that the frontoparietal network is involved in the alerting and orienting attentional function and the executive function is possibly selectively associated with the frontal lobe. The Attention Network Test paradigm produces sensitive, valid and reliable subject estimates of visuospatial attention function in patients with brain lesions, and may be useful for clinical rehabilitation strategy selection for patients with the frontoparietal network lesions.

    Lung cancer accounts for 12% of all cancers and has the highest annual rate of mortality in men and women. The overall aim is cure or prolongation of life without evidence of disease. Almost 60% of patients at the moment of diagnosis are not eligible for radical treatment. Therefore soothing and supportive treatment is the only treatment of choice. Patients with lung cancer who have symptoms of dyspnea, chronic cough, severe pain, exhaustion and cachexia syndrome, fear and depression and significantly reduced physical and intellectual activities are qualified for inpatient or home palliative care. Knowledge about various methods used in palliative treatment allows one to alleviate symptoms that occur in an advanced stage of disease with an expected short survival period. Methods of oncological treatment that are often used in patients with advanced lung cancer include radiotherapy and chemotherapy. Drawing attention to the earlier implementation of palliative care is an objective of research carried out during recent years. Advances in surgical and conservative treatment of these patients have contributed to better outcomes and longer survival time. PMID:24596508

    Diabetes mellitus is a common disease and its prevalence is increasing worldwide. In various studies up to 30%-70% of patients present dysfunction and complications related to the gut. To date several clinical studies have demonstrated that autonomic nervous system neuropathy and generalized neuropathy of the central nervous system (CNS) may play a major role. This systematic review provides an overview of the neurodegenerative changes that occur as a consequence of diabetes with a focus on the CNS changes and gastrointestinal (GI) dysfunction. Animal models where diabetes was induced experimentally support that the disease induces changes in CNS. Recent investigations with electroencephalography and functional brain imaging in patients with diabetes confirm these structural and functional brain changes. Encephalographic studies demonstrated that altered insular processing of sensory stimuli seems to be a key player in symptom generation. In fact one study indicated that the more GI symptoms the patients experienced, the deeper the insular electrical source was located. The electroencephalography was often used in combination with quantitative sensory testing mainly showing hyposensitivity to stimulation of GI organs. Imaging studies on patients with diabetes and GI symptoms mainly showed microstructural changes, especially in brain areas involved in visceral sensory processing. As the electrophysiological and imaging changes were associated with GI and autonomic symptoms they may represent a future therapeutic target for treating diabetics either pharmacologically or with neuromodulation.

    Rehabilitation following acquired brain injury improves health outcomes, reduces disability, and improves quality of life. We assessed the cost effectiveness of inpatient rehabilitation after brain injury in individuals with brain injury admitted to the Irish national tertiary specialist rehabilitation centre in 2011. Patients' score on the Disability Rating Scale (DRS) was recorded on admission and at discharge after intensive inpatient rehabilitation. Cost savings attributed to the rehabilitation programme were calculated as the difference between direct care costs on admission and discharge. Direct costs of care were calculated as the weekly cost of the care-assistant hours required to care for patients on the basis of their level of disability or daily nursing-home bed cost when this was required. Of 63 patients, complete DRS information for admission and discharge was available for 41. DRS scores, and therefore average levels of functioning, differed significantly at admission (2.3, between mildly and moderately dependent) and discharge (1.1, independent in special environments, p<0.01). Average weekly care costs fell from €629 to €242, with costs recouped within 30 months. Thus, substantial savings result from inpatient rehabilitation, and these savings could have been greater had we considered also the economic benefit of enabling patients to return to employment.

As the electrophysiological and imaging changes were associated with GI and autonomic symptoms they may represent a future therapeutic target for treating diabetics either pharmacologically or with neuromodulation.

    Purpose: Resting-state functional magnetic resonance imaging (fMRI) studies have demonstrated the disruptions of multiple brain networks in tinnitus patients. Nonetheless, several studies found no differences in network processing between tinnitus patients and healthy controls (HCs). Its neural bases are poorly understood. To identify aberrant brain network architecture involved in chronic tinnitus, we compared the resting-state fMRI (rs-fMRI) patterns of tinnitus patients and HCs. Materials and Methods: Chronic tinnitus patients (n = 24) with normal hearing thresholds and age-, sex-, education- and hearing threshold-matched HCs (n = 22) participated in the current study and underwent the rs-fMRI scanning. We used degree centrality (DC) to investigate functional connectivity (FC) strength of the whole-brain network and Granger causality to analyze effective connectivity in order to explore directional aspects involved in tinnitus. Results: Compared to HCs, we found significantly increased network centrality in bilateral superior frontal gyrus (SFG). Unidirectionally, the left SFG revealed increased effective connectivity to the left middle orbitofrontal cortex (OFC), left posterior lobe of cerebellum (PLC), left postcentral gyrus, and right middle occipital gyrus (MOG) while the right SFG exhibited enhanced effective connectivity to the right supplementary motor area (SMA). In addition, the effective connectivity from the bilateral SFG to the OFC and SMA showed positive correlations with tinnitus distress. Conclusions: Rs-fMRI provides a new and novel method for identifying aberrant brain network architecture. Chronic tinnitus patients have disrupted FC strength and causal connectivity mostly in non-auditory regions, especially the prefrontal cortex (PFC). The current findings will provide a new perspective for understanding the neuropathophysiological mechanisms in chronic tinnitus. PMID:27458377

    We report a case of brain metastasis from rectal cancer a long time after the initial resection. A 62-year-old woman, diagnosed with lower rectal cancer with multiple synchronous liver and lung metastases, underwent abdominoperineal resection after preoperative radiochemotherapy (40 Gy at the pelvis, using the de Gramont regimen FL therapy: 1 kur). The histological diagnosis was a moderately differentiated adenocarcinoma. Various regimens of chemotherapy for unresectable and metastatic colorectal cancer were administered, and a partial response was obtained; thereby, the metastatic lesions became resectable. The patient underwent partial resection of the liver and lung metastases. Pathological findings confirmed that both the liver and lung lesions were metastases from the rectal cancer. A disease-free period occurred for several months; however, there were recurrences of the lung metastases, so we started another round of chemotherapy. After 8 months, she complained of vertigo and dizziness. A left cerebellar tumor about 3 cm in diameter was revealed by MRI and neurosurgical excision was performed. Pathological findings confirmed a cerebellar metastasis from the rectal cancer. Twenty months after resection of the brain tumor, the patient complained of a severe headache. A brain MRI showed hydrocephalia, and carcinomatous meningitis from rectal cancer was diagnosed by a spinal fluid cytology test. A ventriculo-peritoneal shunt was inserted, but the cerebrospinal pressure did not decreased and she died 20 months after the first surgery. Although brain metastasis from colorectal cancer is rare, the number of patients with brain metastasis is thought to increase in the near future. Chemotherapy for colorectal cancer is effective enough to prolong the survival period even if multiple metastases have occurred. However, after a long survival period with lung metastases such as in our case, there is a high probability of developing brain metastases. PMID:26805112

    A factor structure underlying DSM-IV diagnoses has been previously reported in neurologically intact patients. The authors determined the brain regions associated with factors underlying DSM-IV diagnoses and compared the ability of DSM-IV diagnoses, factor scores, and self-report measures to account for the neuroanatomical findings in patients with penetrating brain injuries. This prospective cohort study included 254 Vietnam War veterans: 199 with penetrating brain injuries and 55 matched control participants. Measures include DSM-IV diagnoses (from a Structured Clinical Interview for DSM), self-report measures of depression and anxiety, and CT scans. Factors underlying DSM-IV diagnoses were determined using an exploratory factor analysis and correlated with percent of brain regions affected. The ability of the factor scores, DSM-IV diagnoses, and the self-report psychiatric measures to account for the anatomical variance was compared with multiple regressions. Internalizing and externalizing factors were identified in these brain-injured patients. Damage to the left amygdala and bilateral basal ganglia was associated with lower internalizing factor scores, and damage to the left medial orbitofrontal cortex (OFC) with higher, and bilateral hippocampi with lower, externalizing factor scores. Factor scores best predicted left amygdala and bilateral hippocampal involvement, whereas DSM-IV diagnoses best predicted bilateral basal ganglia and left OFC involvement. Damage to the limbic areas involved in the processing of emotional and reward information, including structures involved in the National Institute of Mental Health's Research Domain Criteria Negative Valence Domain, influences the development of internalizing and externalizing psychiatric symptoms. Self-report measures underperformed DSM-IV and factor scores in predicting neuroanatomical findings. PMID:26715034

    Ninety-four patients with limited stage small cell lung cancer treated between 1981 and 1985 with a regimen including prophylactic brain irradiation (PBI) after combination chemotherapy were assessed for compliance with PBI, brain relapse, and neurologic morbidity. Seventy-seven percent of patients had PBI and of these, 22% developed brain metastases after a median time of 11 months post treatment. The brain was the apparent unique initial site of relapse in 10% of PBI cases but more commonly brain relapse was preceded or accompanied by failure at other sites, especially the chest. Brain metastases were the greatest cause of morbidity in 50% of PBI failures. Twelve of 14 PBI patients alive 2 years after treatment had oncologic, neurologic, and neuropsychological evaluation, and brain CT. All long-term survivors were capable of self care and none fulfilled diagnostic criteria for dementia, with three borderline cases. One third had pretreatment neurologic dysfunction and two thirds post treatment neurologic symptoms, most commonly recent memory loss. Fifty percent had subtle motor findings. Intellectual functioning was at the 38th percentile with most patients having an unskilled occupational history. Neuropsychologic impairment ratings were borderline in three cases and definitely impaired in seven cases. CT scans showed brain atrophy in all cases with mild progression in those having a pre-treatment baseline. Periventricular and subcortical low density lesions identical to the CT appearance of subcortical arteriosclerotic encephalopathy were seen in 82% of posttreatment CT studies, and lacunar infarcts in 54%. Neuropsychologic impairment scores and the extent of CT periventricular low density lesions were strongly associated.

    Cirrhosis is associated with brain dysfunction known as hepatic encephalopathy (HE). The mechanisms behind HE are unclear although hyperammonemia and systemic inflammation through gut dysbiosis have been proposed. We aimed to define the individual contribution of specific gut bacterial taxa towards astrocytic and neuronal changes in brain function using multi-modal MRI in patients with cirrhosis. 187 subjects (40 controls, 147 cirrhotic; 87 with HE) underwent systemic inflammatory assessment, cognitive testing, stool microbiota analysis and brain MRI analysis. MR spectroscopy (MRS) changes of increased Glutamate/glutamine, reduced myo-inositol and choline are hyperammonemia-associated astrocytic changes, while diffusion tensor imaging (DTI) demonstrates changes in neuronal integrity and edema. Linkages between cognition, MRI parameters and gut microbiota were compared between groups. We found that HE patients had a significantly worse cognitive performance, systemic inflammation, dysbiosis and hyperammonemia compared to controls and cirrhotics without HE. Specific microbial families (autochthonous taxa negatively and Enterobacteriaceae positively) correlated with MR spectroscopy and hyperammonemia-associated astrocytic changes. On the other hand Porphyromonadaceae, were only correlated with neuronal changes on DTI without linkages with ammonia. We conclude that specific gut microbial taxa are related to neuronal and astrocytic consequences of cirrhosis-associated brain dysfunction. PMID:27225869

    Numerous studies have been carried out among patients admitted in intensive care unit (ICU) having primary endocrine pathology, endocrine manifestations of systemic diseases or post-endocrine tissue surgery. However, minimal literary evidence is available highlighting the endocrine changes occurring during brain death in critically ill patients. A precise and timely diagnosis of brain death is required to convey the relatives about the prognosis and also to possibly plan for organ retrieval for transplantation purposes. The diagnosis of this condition as of today remains largely a clinical one. Brain death is associated with a multitude of endocrinological alterations which are yet to be completely unraveled and understood. Evaluating these endocrinological modifications lends us an added vista to add to the existing clinical parameters which might help us to confirm the diagnosis of brain death with a higher degree of precision. Moreover, since the efficacy of hormone replacement therapy to benefit in organ retrieval remains yet unproven, newer diagnostic modalities and research studies are definitely called for to strategize the optimal dosage and duration of such therapies.

    In response to recent studies, we investigated an association between perioperative β-blockade and breast cancer metastases. First, a retrospective study examining perioperative β-blocker use and cancer recurrence and metastases was conducted on 1,029 patients who underwent breast cancer surgery at the City of Hope Cancer Center between 2000 and 2010. We followed the clinical study and examined proliferation, migration, and invasion in vitro of primary and brain-metastatic breast cancer cells in response to β2-activation and inhibition. We also investigated in vivo the metastatic potential of propranolol-treated metastatic cells. For stage II breast cancer patients, perioperative β-blockade was associated with decreased cancer recurrence using Cox regression analysis (hazard's ratio =0.51; 95% CI: 0.23–0.97; p=0.041). Triple-negative (TN) brain-metastatic cells were found to have increased β2-adrenergic receptor mRNA and protein expression relative to TN primary cells. In response to β2-adrenergic receptor activation, TN brain-metastatic cells also exhibited increased cell proliferation and migration relative to the control. These effects were abrogated by propranolol. Propranolol decreased β2-adrenergic receptor-activated invasion. In vivo, propranolol treatment of TN brain-metastatic cells decreased establishment of brain metastases. Our results suggest that stress and corresponding β2-activation may promote the establishment of brain metastases of TN breast cancer cells. In addition, our data suggest a benefit to perioperative β-blockade during surgery-induced stress with respect to breast cancer recurrence and metastases. PMID:27035124

    Proper nutrition is critical for recovery from traumatic brain injury (TBI). Prompt enteral feeding of moderate to severe TBI patients has been associated with significantly lower mortality and rates of infection. Probiotic supplementation has been associated with significantly lower rates of infection in TBI and other trauma patients. Human studies have suggested that supplementation with omega 3 fats, vitamin D, N-Acetylcysteine, branched chain amino acids, and zinc may be helpful for recovery from TBI. Animal TBI models have suggested that alpha-lipoic acid, magnesium, taurine, coenzyme Q10, and many phytonutrients (such as resveratrol) are also helpful. Unfortunately, recent human clinical trials with citicoline in TBI and stroke patients have produced disappointing results. Much more research is needed on multifaceted nutritional strategies to treat TBI patients in both the immediate post-injury phase and throughout the patients lifespan. PMID:24844176

    Clinical features of high risk brain arteriovenous malformations (BAVMs) are well characterized. However, pathological evidences about the differences that are possessed by high risk patients are still lacking. We reviewed archived routine hematoxylin-eosin specimens from a total of 54 surgical treated BAVMs. The histopathological features in nidus were semi-quantitatively analyzed. We obtained the pathological differences of BAVMs nidus between several clinical features. Among the analyzed pathological features, the significant differences were observed in degree of venous enlargement and intimal hyperplasia. Juvenile, female, diffuse nidus, high Spetzler-Martin grade, and low flow patients had a lesser degree of those parameters compared to adult, male, compact nidus, low Spetzler-Martin grade and high flow patients. High risk profiles of BAVMs patients were well-reflected in the nidus pathology. Therefore, juvenile, female, diffuse nidus, and low flow in Japanese BAVMs patients might have different vascular remodeling process that predispose to higher tendency of hemorrhage. PMID:27053330

    Prospective series showing the importance of computerized stereotactic brain biopsy in the management of AIDS patients neurologically symptomatic and confirmed by images. Patients undergone an algorithm step by step done by their own doctors and referred to us for stereotactic biopsy. Our protocol was opened in August 1995 and closed in December 1996. Twenty patients were biopsied. This protocol is similar to the Levy's one (Chicago IL, USA). We have got diagnosis in all cases. Lymphoma was predominant and followed by toxoplasmosis, progressive multifocal leukoencephalopathy and HIV encephalopathy. We included one patient with diploic giant cells lymphoma. Our mortality and morbidity was zero. By these results we conclude that stereotactic biopsy in AIDS patients is safe and effective. PMID:9698730

    Objective Brain metastases occur in one-third of all non-small-cell lung cancer patients. Due to restrictive transport at the blood–brain barrier, many drugs provide poor control of metastases in the brain. The aim of this study was to compare erlotinib with pemetrexed as second-/third-line treatment in patients with lung adenocarcinoma with asymptomatic brain metastases. Methods From January 2012 to June 2014, all lung adenocarcinoma patients with asymptomatic brain metastases who received treatment with erlotinib or pemetrexed as second-/third-line treatment were retrospectively reviewed. Chi-square and log-rank tests were used to perform statistical analysis. Results The study enrolled 99 patients, of which 44 were positive for EGFR mutation. Median progression-free survival (PFS) in months was not significantly different between the erlotinib- and pemetrexed-treated groups (4.2 vs 3.4 months; 95% confidence interval [CI]: 2.01–6.40 vs 2.80–5.00, respectively; P=0.635). Median PFS was found to be significantly longer in EGFR mutation–positive patients in the erlotinib-treated group (8.0 months; 95% CI 5.85–10.15) compared to the pemetrexed group (3.9 months; 95% CI: 1.25–6.55; P=0.032). The most common treatment-related side effect was mild-to-moderate rash and the most common drug-related side effects in the pemetrexed-group were vomiting and nausea. Conclusion Erlotinib and pemetrexed may be used as second-/third-line treatment in lung adenocarcinoma patients with asymptomatic brain metastases, and detection of EGFR mutation status is very important in these patients. EGFR mutation–positive lung adenocarcinoma patients with asymptomatic brain metastases showed longer PFS when treated with erlotinib as opposed to pemetrexed. PMID:27143936

    Infertility can arise as a consequence of treatment of oncological conditions. The parallel and continued improvement in both the management of oncology and fertility cases in recent times has brought to the forefront the potential for fertility preservation in patients being treated for cancer. Many survivors will maintain their reproductive potential after the successful completion of treatment for cancer. However total body irradiation, radiation to the gonads, and certain high dose chemotherapy regimens can place women at risk for acute ovarian failure or premature menopause and men at risk for temporary or permanent azoospermia. Providing information about risk of infertility and possible interventions to maintain reproductive potential are critical for the adolescent and young adult population at the time of diagnosis. There are established means of preserving fertility before cancer treatment; specifically, sperm cryopreservation for men and in vitro fertilization and embryo cryopreservation for women. Several innovative techniques are being actively investigated, including oocyte and ovarian follicle cryopreservation, ovarian tissue transplantation, and in vitro follicle maturation, which may expand the number of fertility preservation choices for young cancer patients. Fertility preservation may also require some modification of cancer therapy; thus, patients’ wishes regarding future fertility and available fertility preservation alternatives should be discussed before initiation of therapy.

    Purpose We reviewed the survival time for patients with primary brain tumors undergoing treatment with stereotactic radiation methods at the Masaryk Memorial Cancer Institute Brno. We also identified risk factors and characteristics, and described their influence on survival time. Methods In summarizing survival data, there are two functions of principal interest, namely, the survival function and the hazard function. In practice, both of them can depend on some characteristics. We focused on nonparametric methods, propose a method based on kernel smoothing, and compared our estimates with the results of the Cox regression model. The hazard function is conditional to age and gross tumor volume and visualized as a color-coded surface. A multivariate Cox model was also designed. Results There were 88 patients with primary brain cancer, treated with stereotactic radiation. The median survival of our patient cohort was 47.8 months. The estimate of the hazard function has two peaks (about 10 months and about 40 months). The survival time of patients was significantly different for various diagnoses (p≪0.001), KI (p = 0.047) and stereotactic methods (p = 0.033). Patients with a greater GTV had higher risk of death. The suitable threshold for GTV is 20 cm3. Younger patients with a survival time of about 50 months had a higher risk of death. In the multivariate Cox regression model, the selected variables were age, GTV, sex, diagnosis, KI, location, and some of their interactions. Conclusion Kernel methods give us the possibility to evaluate continuous risk variables and based on the results offer risk-prone patients a different treatment, and can be useful for verifying assumptions of the Cox model or for finding thresholds of continuous variables.

  13. Breakthrough pain in cancer patients.

    PubMed

    Zeppetella, G

    2011-08-01

    Breakthrough pain is a transient exacerbation of pain that occurs either spontaneously or in relation to a specific predictable or unpredictable trigger, despite relatively stable and adequately controlled background pain. A typical episode of breakthrough pain has a fast onset and short duration, yet despite the self-limiting nature of each breakthrough pain, the repeated episodes can have a significant effect on patients' quality of life. Normal-release oral opioids have been the mainstay pharmacological approach for patients who are receiving an around the clock opioid regimen, but the onset and duration of action of oral opioids such as morphine may not be suitable for treating many breakthrough pains. Efforts to provide non-parenteral opioid formulations that could provide more rapid, and more effective, relief of breakthrough pain have led to the development of transmucosal opioid formulations.

    Purpose To determine the predictors of distress in older patients with cancer. Patients and Methods Patients age ≥ 65 years with a solid tumor or lymphoma completed a questionnaire that addressed these geriatric assessment domains: functional status, comorbidity, psychological state, nutritional status, and social support. Patients self-rated their level of distress on a scale of zero to 10 using a validated screening tool called the Distress Thermometer. The relationship between distress and geriatric assessment scores was examined. Results The geriatric assessment questionnaire was completed by 245 patients (mean age, 76 years; standard deviation [SD], 7 years; range, 65 to 95 years) with cancer (36% stage IV; 71% female). Of these, 87% also completed the Distress Thermometer, with 41% (n = 87) reporting a distress score of ≥ 4 on a scale of zero to 10 (mean score, 3; SD, 3; range, zero to 10). Bivariate analyses demonstrated an association between higher distress (≥ 4) and poorer physical function, increased comorbid medical conditions, poor eyesight, inability to complete the questionnaire alone, and requiring more time to complete the questionnaire. In a multivariate regression model based on the significant bivariate findings, poorer physical function (increased need for assistance with instrumental activities of daily living [P = .015] and lower physical function score on the Medical Outcomes Survey [P = .018]) correlated significantly with a higher distress score. Conclusion Significant distress was identified in 41% of older patients with cancer. Poorer physical function was the best predictor of distress. Further studies are needed to determine whether interventions that improve or assist with physical functioning can help to decrease distress in older adults with cancer. PMID:19652074

    Purpose: To estimate the risk of a second malignancy after treatment of a primary brain cancer using passive scattered proton beam therapy. The focus was on the cancer risk caused by neutrons outside the treatment volume and the dependency on the patient's age. Methods and Materials: Organ-specific neutron-equivalent doses previously calculated for eight different proton therapy brain fields were considered. Organ-specific models were applied to assess the risk of developing solid cancers and leukemia. Results: The main contributors (>80%) to the neutron-induced risk are neutrons generated in the treatment head. Treatment volume can influence the risk by up to a factor of {approx}2. Young patients are subject to significantly greater risks than are adult patients because of the geometric differences and age dependency of the risk models. Breast cancer should be the main concern for females. For males, the risks of lung cancer, leukemia, and thyroid cancer were significant for pediatric patients. In contrast, leukemia was the leading risk for an adult. Most lifetime risks were <1% (70-Gy treatment). The only exceptions were breast, thyroid, and lung cancer for females. For female thyroid cancer, the treatment risk can exceed the baseline risk. Conclusion: The risk of developing a second malignancy from neutrons from proton beam therapy of a brain lesion is small (i.e., presumably outweighed by the therapeutic benefit) but not negligible (i.e., potentially greater than the baseline risk). The patient's age at treatment plays a major role.

    Background Neuropathic characteristics are highly involved in the development of chronic pain both physically and psychologically. However, little is known about the relationship between neuropathic characteristics and brain morphological alteration. Objectives The aim of this study is to investigate the mechanisms of chronic pain development by examining the above-mentioned relationships by voxel-based morphometry in patients with chronic pain. Methods First, we assessed neuropathic characteristics using the painDETECT Questionnaire in 12 chronic pain patients. Second, to assess the gray matter volume changes by voxel-based morphometry, we conducted magnetic resonance imaging of the brain. We applied multiregression analysis of these two assessment methods. Results There were significant positive correlations between painDETECT Questionnaire scores and the gray matter volume in the bilateral anterior cingulate cortex and right posterior cingulate cortex. Conclusions Our findings suggest that neuropathic characteristics strongly affect the brain regions related to modulation of pain in patients with chronic pain and, therefore, contribute to the severity of chronic pain.

  17. Restoring the DHA levels in the brains of Zellweger patients.

    Patients with the Zellweger syndrome and its variants have very low levels of docosahexaenoic acid (DHA) in the brain, retina, and other tissues. Such a marked DHA deficiency could be related to the pathogenesis of peroxisomal disorders. Therefore, restoring the DHA levels in these patients can probably improve the clinical course of the disease. With this rationale, 20 patients with generalized peroxisomal disorders have been treated to date with DHA ethyl ester, at daily doses of 100-500 mg, for variable periods of time. Treatment has been always accompanied by a nutritious diet, normal for the age, in order to provide all the necessary nutrients and avoid a polyunsaturated fatty acid (PUFA) imbalance. The most constant improvement has been normalization of the DHA levels and liver function. Vision has improved in about half the patients and muscle tone has generally increased. Magnetic resonance imaging (MRI) examination revealed improvement of myelination in 9 patients. Significantly, the clinical improvement has been most marked in those patients who started the treatment before 6 mo of age. Biochemically, the plasma very long-chain fatty acids (VLCFA) 26:0 and 26:1n-9 decreased markedly despite the complete diet provided. In erythrocytes, the plasmalogen ratio 18: ODMA/18:0 increased in most cases, and sometimes even normalized. All these beneficial effects suggest that DHA deficiency plays a fundamental role in the pathogenesis of peroxisomal disease. Because DHA accretion is maximal during early brain development, it is essential to initiate the treatment as soon as possible. Otherwise, restoration of brain DHA levels and prevention of further damage will not be possible. PMID:11478386

    Breast cancer is a major health problem worldwide. The median survival duration for patients with metastatic breast cancer is two to three years. Approximately 1% of populations worldwide have schizophrenia. The manner in which schizophrenic patients fare when diagnosed with metastatic breast carcinoma (MBC) was evaluated. We queried the National Department of Veterans Affairs (DVA) datasets using computer codes for a pre-existing diagnosis of schizophrenia and a later diagnosis of breast carcinoma. Chart-based data concerning the identified subjects were then requested. Previously determined inclusion and exclusion criteria were applied to select evaluable patients from the medical records, prior to extracting demographic details and data concerning the treatment course in each subject. Ten patients had distant metastases at initial diagnosis, while seven developed MBC following prior curative-intent treatment. Two patients refused therapy. Ten did not comply with recommended management. Five harmed or threatened physicians, other caregivers or themselves. Schizophrenic patients with MBC often fail to understand the nature of their illnesses. Often they do not accept palliative treatment, while a number of them do not comply with therapy, once initiated. They often exhibit behaviors that are detrimental to themselves or others. Formal psychiatric consultation is therefore necessary in patients. Several detrimental behaviors may be predicted reliably by history alone. PMID:24649175

    Gastric cancer (GC) is one of the most frequent malignant diseases in the elderly. Systemic chemotherapy showed an improvement of quality of life and survival benefit compared to supportive care alone in patients with advanced GC. Because comorbidities or age-related changes in pharmacokinetics and pharmacodynamics may lead to higher toxicity, however, many oncologists hesitate to recommend elderly patients to receive chemotherapy. Available data suggest that elderly patients with GC are able to tolerate and benefit from systemic chemotherapy to the same extent as younger patients. The age alone should not be the only criteria to preclude effective chemotherapy. However, proper patient selection is extremely important to deliver effective treatment safely. A comprehensive geriatric assessment (CGA) is a useful method to assess life expectancy and risk of morbidity in older patients and to guide providing optimal treatment. Treatment should be personalized based on the nature of the disease, the life expectancy, the risk of complication, and the patient's preference. Combination chemotherapy can be considered for older patients with metastatic GC who are classified as non-frail patients by CGA. For frail or vulnerable patients, however, monotherapy or only symptomatic treatment may be desirable. Targeted agents seem to be promising treatment options for elderly patients with GC considering their better efficacy and less toxicity. PMID:26722364

    Abstract Stroke is a dramatic complication of pancreatic cancer with mechanisms related to oncological disease. A better description of the characteristics of cerebrovascular events would help better understand the pathogeny and protect vulnerable patients. We thus conducted a descriptive analysis of clinical, biological, and radiological features of patients from our centers and literature. We reviewed consecutive cases of patients who presented cerebrovascular events and pancreatic cancer in 4 stroke units in Lorrain (France) between January 1, 2009 and March 31, 2015, and all reported cases of literature. We identified 17 cases in our centers and 18 reported cases. Fifty-seven per cent of patients were male. Median age was 63 ± 14 years and ranged from 23 to 81 years. All cerebral events were ischemic. At the onset of stroke, pancreatic cancer had already been diagnosed in 59% of the patients in our centers for a mean time of 5.4 months. Five of them (29%) were being treated with gemcitabine and 2 (12%) with folfirinox. Adenocarcinoma at metastatic stage was reported in 82% of cases overall. Brain imaging revealed disseminated infarctions in 64%. High median levels of D-dimer (7600 ± 5 × 107 μg/L), C-reactive protein (63 ± 43 mg/L), and elevated prothrombin time (19 ± 6 seconds) were found. Thirty-six per cent of patients explored with echocardiography were diagnosed with nonbacterial thrombotic endocarditis. Ten of our patients received anticoagulant therapy as secondary stroke prevention without any documented recurrence. Nevertheless, outcome was poor with a median survival time of 28 ± 14 days after stroke onset. Cerebral ischemic events occur at advanced stages of pancreatic cancer, most likely by a thromboembolic mechanism. Disseminated infarctions and high D-dimer, C-reactive protein levels, and a high prothrombin time are the most constant characteristics found in this context. All patients should be screened for

    Metastasis to the skeletal muscle from gastric cancer is relatively rare. We report cases of 3 patients undergoing chemotherapy for gastric cancer with metastasis to the skeletal muscle. Case 1: A man in his 70s was diagnosed with advanced gastric cancer (cT4N3M1P0, stage IV), with metastasis to the lung, brain, lymph node, and iliopsoas muscle. Case 2: A man in his 60s was diagnosed with advanced gastric cancer (cT3N3M1P0, stage IV), with metastasis to the brain, lung, lymph node, and iliopsoas muscle. Case 3: A man in his 50s was diagnosed with advanced gastric cancer (cT4N3M1P0, stage IV), with metastasis to the urinary duct, lymph node, back muscle, and iliopsoas muscle. All 3 patients died within 7-8 months after the diagnosis due to progressive disease despite chemotherapy. The prognosis of these 3 patients was significantly poorer than that of patients in our hospital with metastasis not involving the skeletal muscle (p<0.01). Accordingly, metastasis to the skeletal muscle may be an adverse prognostic factor in gastric cancer. PMID:26602403

    Purpose: We sought to determine the risk of leptomeningeal disease (LMD) in patients treated with stereotactic radiosurgery (SRS) targeting the postsurgical resection cavity of a brain metastasis, deferring whole-brain radiation therapy (WBRT) in all patients. Methods and Materials: We retrospectively reviewed 175 brain metastasis resection cavities in 165 patients treated from 1998 to 2011 with postoperative SRS. The cumulative incidence rates, with death as a competing risk, of LMD, local failure (LF), and distant brain parenchymal failure (DF) were estimated. Variables associated with LMD were evaluated, including LF, DF, posterior fossa location, resection type (en-bloc vs piecemeal or unknown), and histology (lung, colon, breast, melanoma, gynecologic, other). Results: With a median follow-up of 12 months (range, 1-157 months), median overall survival was 17 months. Twenty-one of 165 patients (13%) developed LMD at a median of 5 months (range, 2-33 months) following SRS. The 1-year cumulative incidence rates, with death as a competing risk, were 10% (95% confidence interval [CI], 6%-15%) for developing LF, 54% (95% CI, 46%-61%) for DF, and 11% (95% CI, 7%-17%) for LMD. On univariate analysis, only breast cancer histology (hazard ratio, 2.96) was associated with an increased risk of LMD. The 1-year cumulative incidence of LMD was 24% (95% CI, 9%-41%) for breast cancer compared to 9% (95% CI, 5%-14%) for non-breast histology (P=.004). Conclusions: In patients treated with SRS targeting the postoperative cavity following resection, those with breast cancer histology were at higher risk of LMD. It is unknown whether the inclusion of whole-brain irradiation or novel strategies such as preresection SRS would improve this risk or if the rate of LMD is inherently higher with breast histology.

    The net survival of a patient diagnosed with a given disease is a quantity often interpreted as the hypothetical survival probability in the absence of causes of death other than the disease. In a relative survival framework, net survival summarises the excess mortality that patients experience compared with their relevant reference population. Based on follow-up data from the Finnish Cancer Registry, we derived simulation scenarios that describe survival of patients in eight cancer sites reflecting different excess mortality patterns in order to compare the performance of the classical Ederer II estimator and the new estimator proposed by Pohar Perme et al. At 5 years, the age-standardised Ederer II estimator performed equally well as the Pohar Perme estimator with the exception of melanoma in which the Pohar Perme estimator had a smaller mean squared error (MSE). At 10 and 15 years, the age-standardised Ederer II performed most often better than the Pohar Perme estimator. The unstandardised Ederer II estimator had the largest MSE at 5 years. However, its MSE was often superior to those of the other estimators at 10 and 15 years, especially in sparse data. Both the Pohar Perme and the age-standardised Ederer II estimator are valid for 5-year net survival of cancer patients. For longer-term net survival, our simulation results support the use of the age-standardised Ederer II estimator. Copyright © 2015 John Wiley & Sons, Ltd. PMID:26707551

    Treatment for prostate cancer (PCa) has evolved significantly over the last decade. PCa is the most prevalent non-skin cancer and the second leading cause of cancer death in men, and it has an increased incidence and prevalence in older men. As a result, physicians and patients are faced with the challenge of identifying optimal treatment strategies for localized, biochemical recurrent, and advanced PCa in the older population. When older patients are appropriately selected, treatment for PCa results in survival benefits and toxicity profiles similar to those experienced in younger patients. However, underlying health status and age-related changes can have an impact on tolerance of hormonal therapy and chemotherapy in men with advanced disease. Therefore, the heterogeneity of the elderly population necessitates a multidimensional assessment to maximize the benefit of medical and/or surgical options. Providing clinicians with the requisite health status data on which to base treatment decisions would help ensure that older patients with PCa receive optimal therapy if it will benefit them and/or active surveillance or best supportive care if it will not. We provide a review of the existing evidence to date on the management of PCa in the older population. PMID:25071137

    Infertility can arise as a consequence of treatment of oncological conditions. The parallel and continued improvement in both the management of oncology and fertility cases in recent times has brought to the fore-front the potential for fertility preservation in patients being treated for cancer. Oncologists must be aware of situations where their treatment will affect fertility in patients who are being treated for cancer and they must also be aware of the pathways available for procedures such as cryopreservation of gametes and/or embryos. Improved cancer care associated with increased cure rates and long term survival, coupled with advances in fertility treatment means that it is now imperative that fertility preservation is considered as part of the care offered to these patients. This can only be approached within a multidisciplinary setting. There are obvious challenges that still remain to be resolved, especially in the area of fertility preservation in prepubertal patients. These include ethical issues, such as valid consent and research in the area of tissue retrieval, cryopreservation, and transplantation. PMID:20379357

    Purpose: Estimating the cost-effectiveness of whole-brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS), including Gamma Knife radiosurgery (GKRS), requires the quantitative measurement of patients’ health states after treatment. We sought to quantify individuals’ preferences for the relevant health states after WBRT or GKRS for brain metastases on a 0 to 1 scale, where 1 is perfect health and 0 is death. Methods: We prospectively measured utilities in patients with brain metastases evaluated at Yale for consideration of WBRT and/or GKRS, as well as oncology nurses who had cared for patients with brain metastases before and after WBRT or GKRS, using the Standard Gamble (SG) technique. Demographic information was also collected. Nonparametric tests were used to compare potential differences in utility values and for subgroups based on demographic characteristics. Results: There were 24 patients and 31 nurses who completed the study between December 2013 and May 2015. Median utilities ranged from 0.85 for the status-post (S/P) GKRS state to 0.25 (for neurologic dying). The median utility of being S/P WBRT was 0.70 compared to 0.85 S/P GKRS (p < 0.001). The cognitive decline from WBRT was associated with a notably low utility score of 0.30. There were no statistically significant differences between patients’ and nurses’ median utility scores. Conclusions: These SG utilities provide unique insights into brain metastases-related health states from the patient and provider perspective. As perceived by individuals with direct knowledge of the health states in question, WBRT has a significantly lower utility compared to GKRS. Cognitive decline following WBRT is associated with significant perceived reduction in quality of life. Differences in the relative importance of overall survival and quality of life with treatment existed between patients with different stages of disease. These utilities can be used to calculate quality-adjusted life

    Daily interruption of sedative therapy and limitation of deep sedation have been shown in several randomized trials to reduce the duration of mechanical ventilation and hospital length of stay, and to improve the outcome of critically ill patients. However, patients with severe acute brain injury (ABI; including subjects with coma after traumatic brain injury, ischaemic/haemorrhagic stroke, cardiac arrest, status epilepticus) were excluded from these studies. Therefore, whether the new paradigm of minimal sedation can be translated to the neuro-ICU (NICU) is unclear. In patients with ABI, sedation has 'general' indications (control of anxiety, pain, discomfort, agitation, facilitation of mechanical ventilation) and 'neuro-specific' indications (reduction of cerebral metabolic demand, improved brain tolerance to ischaemia). Sedation also is an essential therapeutic component of intracranial pressure therapy, targeted temperature management and seizure control. Given the lack of large trials which have evaluated clinically relevant endpoints, sedative selection depends on the effect of each agent on cerebral and systemic haemodynamics. Titration and withdrawal of sedation in the NICU setting has to be balanced between the risk that interrupting sedation might exacerbate brain injury (e.g. intracranial pressure elevation) and the potential benefits of enhanced neurological function and reduced complications. In this review, we provide a concise summary of cerebral physiologic effects of sedatives and analgesics, the advantages/disadvantages of each agent, the comparative effects of standard sedatives (propofol and midazolam) and the emerging role of alternative drugs (ketamine). We suggest a pragmatic approach for the use of sedation-analgesia in the NICU, focusing on some practical aspects, including optimal titration and management of sedation withdrawal according to ABI severity.

    Abstract Over the past 20 years, cancer patient advocacy groups have demonstrated that patient engagement in cancer care is essential to improving patient quality of life and outcomes. Bladder cancer patient advocacy only began 10 years ago in the United States, but is now expanding around the globe with non-profit organizations established in Canada, the United Kingdom and Italy, and efforts underway in Australia. These organizations, at different levels of maturity, are raising awareness of bladder cancer and providing essential information and resources to bladder cancer patients and their families. The patient advocacy organizations are also helping to advance research efforts by funding research proposals and facilitating research collaborations. Strong partnerships between these patient advocates and the bladder cancer medical community are essential to ensuringsustainability for these advocacy organizations, increasing funding to support advances in bladder cancer treatment, and improving patient outcomes.

    Although substantial evidence has established that microglia and astrocytes play a key role in the establishment and maintenance of persistent pain in animal models, the role of glial cells in human pain disorders remains unknown. Here, using the novel technology of integrated positron emission tomography-magnetic resonance imaging and the recently developed radioligand (11)C-PBR28, we show increased brain levels of the translocator protein (TSPO), a marker of glial activation, in patients with chronic low back pain. As the Ala147Thr polymorphism in the TSPO gene affects binding affinity for (11)C-PBR28, nine patient-control pairs were identified from a larger sample of subjects screened and genotyped, and compared in a matched-pairs design, in which each patient was matched to a TSPO polymorphism-, age- and sex-matched control subject (seven Ala/Ala and two Ala/Thr, five males and four females in each group; median age difference: 1 year; age range: 29-63 for patients and 28-65 for controls). Standardized uptake values normalized to whole brain were significantly higher in patients than controls in multiple brain regions, including thalamus and the putative somatosensory representations of the lumbar spine and leg. The thalamic levels of TSPO were negatively correlated with clinical pain and circulating levels of the proinflammatory citokine interleukin-6, suggesting that TSPO expression exerts pain-protective/anti-inflammatory effects in humans, as predicted by animal studies. Given the putative role of activated glia in the establishment and or maintenance of persistent pain, the present findings offer clinical implications that may serve to guide future studies of the pathophysiology and management of a variety of persistent pain conditions.

    Purpose: The use of prophylactic cranial irradiation (PCI) in small cell lung cancer (SCLC) with surgical resection has not been fully identified. This study undertook to assess the factors affecting the risk of brain metastases in patients with stage I-III SCLC after surgical resection. The implications of PCI treatment for these patients are discussed. Methods and Materials: One hundred twenty-six patients treated with surgical resection for stage I-III SCLC from January 1998-December 2009 were retrospectively analyzed to elucidate the risk factors of brain metastases. Log-rank test and Cox regression model were used to determine the risk factors of brain metastases. Results: The median survival time for this patient population was 34 months, and the 5-year overall survival rate was 34.9%. For the whole group, 23.0% (29/126) of the patients had evidence of metastases to brain. Pathologic stage not only correlated with overall survival but also significantly affected the risk of brain metastases. The 5-year survival rates for patients with pathologic stages I, II, and III were 54.8%, 35.6%, and 14.1%, respectively (P=.001). The frequency of brain metastases in patients with pathologic stages I, II, and III were 6.25% (2/32), 28.2% (11/39), and 29.1% (16/55) (P=.026), respectively. A significant difference in brain metastases between patients with complete resection and incomplete resection was also observed (20.5% vs 42.9%, P=.028). The frequency of brain metastases was not found to be correlated with age, sex, pathologic type, induction chemotherapy, adjuvant chemotherapy, or adjuvant radiation therapy. Conclusions: Stage I SCLC patients with complete resection had a low incidence of brain metastases and a favorable survival rate. Stage II-III disease had a higher incidence of brain metastases. Thus, PCI might have a role for stage II-III disease but not for stage I disease.

    Breast cancer brain metastasis, occurring in 30% of breast cancer patients at stage IV, is associated with high mortality. The median survival is only 6 months. It is critical to have suitable animal models to mimic the hemodynamic spread of the metastatic cells in the clinical scenario. Here, we are introducing the use of small animal ultrasound imaging to guide an accurate injection of brain tropical breast cancer cells into the left ventricle of athymic nude mice. Longitudinal MRI is used to assessing intracranial initiation and growth of brain metastases. Ultrasound-guided intracardiac injection ensures not only an accurate injection and hereby a higher successful rate but also significantly decreased mortality rate, as compared to our previous manual procedure. In vivo high resolution MRI allows the visualization of hyperintense multifocal lesions, as small as 310 µm in diameter on T2-weighted images at 3 weeks post injection. Follow-up MRI reveals intracranial tumor growth and increased number of metastases that distribute throughout the whole brain. PMID:24637963

    Bone and soft tissue malignancies account for a small portion of brain metastases. In this review, we characterize their incidence, treatments, and prognosis. Most of the data in the literature is based on case reports and small case series. Less than 5% of brain metastases are from bone and soft tissue sarcomas, occurring most commonly in Ewing's sarcoma, malignant fibrous tumors, and osteosarcoma. Mean interval from initial cancer diagnosis to brain metastasis is in the range of 20–30 months, with most being detected before 24 months (osteosarcoma, Ewing sarcoma, chordoma, angiosarcoma, and rhabdomyosarcoma), some at 24–36 months (malignant fibrous tumors, malignant peripheral nerve sheath tumors, and alveolar soft part sarcoma), and a few after 36 months (chondrosarcoma and liposarcoma). Overall mean survival ranges between 7 and 16 months, with the majority surviving < 12 months (Ewing's sarcoma, liposarcoma, malignant fibrous tumors, malignant peripheral nerve sheath tumors, angiosarcoma and chordomas). Management is heterogeneous involving surgery, radiosurgery, radiotherapy, and chemotherapy. While a survival advantage may exist for those given aggressive treatment involving surgical resection, such patients tended to have a favorable preoperative performance status and minimal systemic disease.

    The most frequent intracranial brain tumours are brain metastases. All types of cancer can develop brain metastases but two thirds of brain metastases occurring in adult patients are secondary to one of these three cancers: lung cancer, breast cancer and melanoma. In accordance with these data, this review is focusing on the epidemiology of these three types of cancer. We report here the incidence, risk factors, median time of brain metastases occurrence after diagnosis of the primary cancer, prognosis and median survival for these three types of cancer. We also discuss the clinical implications of these data. The second part of this review is focusing on the Graded Prognostic Assessment scores in all types of primary cancer with brain metastases, how they can be applied in clinical research for a better stratification of patients, and to some extent in clinical practice to guide decisions for personalized treatments. These scores provide a better understanding of the different profiles of clinical evolution that can be observed amongst patients suffering from brain metastases according to the type of primary cancer. We highlighted the most remarkable and useful clinical implications of these data. PMID:25636729

    Functional neuroimaging is an innovative but at this stage underutilized method to assess the efficacy of psychotherapy for depression. Functional magnetic resonance imaging (fMRI) was used in this case study to examine changes in brain activity in a depressed breast cancer patient receiving an 8-session Behavioral Activation Treatment for Depression (BATD), based on the work of Hopko and Lejuez (2007). A music listening paradigm was used during fMRI brain scans to assess reward responsiveness at pre- and posttreatment. Following treatment, the patient exhibited attenuated depression and changes in blood oxygenation level dependence (BOLD) response in regions of the prefrontal cortex and the subgenual cingulate cortex. These preliminary findings outline a novel means to assess psychotherapy efficacy and suggest that BATD elicits functional brain changes in areas implicated in the pathophysiology of depression. Further research is necessary to explore neurobiological mechanisms of change in BATD, particularly the potential mediating effects of reward responsiveness and associated brain functioning.

    Background The brain is a metastatic organ that is most prone to lung adenocarcinoma (LAC). However, the prognosis of patients with brain metastasis remains very poor. In this study, we evaluated the efficacy of icotinib plus whole brain radiation therapy (WBRT) for treating patients with brain metastasis from epidermal growth factor receptor (EGFR)-mutated LAC. Methods All patients received standard WBRT administered to the whole brain in 30 Gy in 10 daily fractions. Each patient was also instructed to take 125 mg icotinib thrice per day beginning from the first day of the WBRT. After completing the WBRT, maintenance icotinib was administered until the disease progressed or intolerable adverse effects were observed. Cranial progression-free survival (CPFS) and overall survival (OS) times were the primary endpoints. Results A total of 43 patients were enrolled in this study. Two patients (4.7%) presented a complete response (CR), whereas 20 patients (46.5%) presented a partial response (PR). The median CPFS and OS times were 11.0 and 15.0 months, respectively. The one-year CPFS rate was 40.0% for the patients harboring EGFR exon 19 deletion and 16.7% for the patients with EGFR exon 21 L858R (P=0.027). Conclusions The concurrent administration of icotinib and WBRT exhibited favorable effects on the patients with brain metastasis. EGFR exon 19 deletion was predictive of a long CPFS following icotinib plus WBRT. PMID:27499937

    Chemotherapy-related cognitive impairment (CRCI) can occur during or after chemotherapy and represents a concern for many patients with cancer. Among older patients with cancer, in whom there is little clinical trial evidence examining side effects like CRCI, many unanswered questions remain regarding risk for and resulting adverse outcomes from CRCI. Given the rising incidence of cancer with age, CRCI is of particular concern for older patients with cancer who receive treatment. Therefore, research related to CRCI in older patients with cancers is a high priority. In this manuscript, we discuss current gaps in research highlighting the lack of clinical studies of CRCI in older adults, the complex mechanisms of CRCI, and the challenges in measuring cognitive impairment in older patients with cancer. Although we focus on CRCI, we also discuss cognitive impairment related to cancer itself and other treatment modalities. We highlight several research priorities to improve the study of CRCI in older patients with cancer. PMID:27197918

    Thrombosis and thromboembolic events contribute to significant morbidity in cancer patients. Venous thrombosis embolism (which includes deep vein thrombosis and pulmonary embolism) accounts for a large percentage of thromboembolic events. Appropriate identification of cancer patients at high risk for venous thromboembolism and management of thromboembolic event is crucial in improving the quality of care for cancer patients. However, thromboembolism in cancer patients is a complex problem and the management has to be tailored to each individual. The focus of this review is to understand the complex pathology, physiology and risk factors that drive the process of venous thrombosis and embolism in cancer patients and the current guidelines in management.

    Introduction The frequency of tracheostomy in patients with traumatic brain injury (TBI) contrasts with the lack of objective criteria for its management. The study arose from the need for a protocol in the decision to remove the tracheal tube. Objective To evaluate the applicability of a protocol for tracheal decannulation. Methods A prospective study with 20 patients, ranging between 21 and 85 years of age (average 33.55), 4 of whom were women (20%) and 16 were men (80%). All patients had been diagnosed by a neurologist as having TBI, and the anatomical region of the lesion was known. Patients were evaluated following criteria for tracheal decannulation through a clinical evaluation protocol developed by the authors. Results Decannulation was performed in 12 (60%) patients. Fourteen (70%) had a score greater than 8 on the Glasgow Coma Scale and only 2 (14%) of these were not able to undergo decannulation. Twelve (60%) patients maintained the breathing pattern with occlusion of the tube and were successfully decannulated. Of the 20 patients evaluated, 11 (55%) showed no signs suggestive of tracheal aspiration, and of these, 9 (82%) began training on occlusion of the cannula. The protocol was relevant to establish the beginning of the decannulation process. The clinical assessment should focus on the patient's condition to achieve early tracheal decannulation. Conclusion This study allowed, with the protocol, to establish six criteria for tracheal decannulation: level of consciousness, respiration, tracheal secretion, phonation, swallowing, and coughing.

    The increasing popularity and availability of electronic cigarettes (i.e., e-cigarettes) in many countries have promoted debate among health professionals as to what to recommend to their patients who might be struggling to stop smoking or asking about e-cigarettes. In the absence of evidence-based guidelines for using e-cigarettes for smoking cessation, some health professionals have urged caution about recommending them due to the limited evidence of their safety and efficacy, while others have argued that e-cigarettes are obviously a better alternative to continued cigarette smoking and should be encouraged. The leadership of the International Association for the Study of Lung Cancer asked the Tobacco Control and Smoking Cessation Committee to formulate a statement on the use of e-cigarettes by cancer patients to help guide clinical practice. Below is this statement, which we will update periodically as new evidence becomes available. PMID:24736063

    Traditional healing is a common practice in low and middle income countries such as Malaysia. Eighty percent of Malaysians consult traditional healers or “bomoh” at some time in their life for health-related issues. The purpose of our study was to explore why breast cancer patients visit traditional healers. This is a qualitative study utilizing in-depth interviews with 11 cancer survivors who sought both traditional and Western medicine. The findings revealed the following reasons for which patients seek traditional healers: (1) recommendation from family and friends, (2) sanction from family, (3) perceived benefit and compatibility, (4) healer credibility, and (5) reservation with Western medicine and system delay. These factors work together and are strongly influenced by the Malaysian cultural context. The issue with the Western health system is common in a developing country with limited health facilities.

    Preservation of fertility is an important issue in the management of young cancer patients. Though embryo cryostorage is a well-established procedure, it can only be availed by couples. Recent studies have indicated increasing success rates with mature and immature oocyte cryopreservation. Cryostorage induces injuries on the human oocytes which can be minimized by slow freezing and vitrification. Selection of candiidates is crucial so that the most suitable technique can be offered without any delay in initiation of cancer therapy. Factors affecting suitability are age of patient, assessment of ovarian reserve, hormonal status and type and stage of neoplastic disease. Encouraging results have been obtained with oocyte in vitro maturation (IVM) followed by vitrification for cryostorage. Data on the use of vitrified eggs in routine in vitro fertilization (IVF) show that pregnancy rates can be comparable to those achieved with fresh oocytes. PMID:25540565

    Patients with primary brain tumors (PBT) face uncertainty related to prognosis, symptoms and treatment response and toxicity. Uncertainty is correlated to negative mood states and symptom severity and interference. This study identified predictors of uncertainty during different treatment stages (newly-diagnosed, on treatment, followed-up without active treatment). One hundred eighty six patients with PBT were accrued at various points in the illness trajectory. Data collection tools included: a clinical checklist/a demographic data sheet/the Mishel Uncertainty in Illness Scale-Brain Tumor Form. The structured additive regression model was used to identify significant demographic and clinical predictors of illness-related uncertainty. Participants were primarily white (80 %) males (53 %). They ranged in age from 19-80 (mean = 44.2 ± 12.6). Thirty-two of the 186 patients were newly-diagnosed, 64 were on treatment at the time of clinical visit with MRI evaluation, 21 were without MRI, and 69 were not on active treatment. Three subscales (ambiguity/inconsistency; unpredictability-disease prognoses; unpredictability-symptoms and other triggers) were different amongst the treatment groups (P < .01). However, patients' uncertainty during active treatment was as high as in newly-diagnosed period. Other than treatment stages, change of employment status due to the illness was the most significant predictor of illness-related uncertainty. The illness trajectory of PBT remains ambiguous, complex, and unpredictable, leading to a high incidence of uncertainty. There was variation in the subscales of uncertainty depending on treatment status. Although patients who are newly diagnosed reported the highest scores on most of the subscales, patients on treatment felt more uncertain about unpredictability of symptoms than other groups. Due to the complexity and impact of the disease, associated symptoms, and interference with functional status, comprehensive assessment of patients

    Although substantial evidence has established that microglia and astrocytes play a key role in the establishment and maintenance of persistent pain in animal models, the role of glial cells in human pain disorders remains unknown. Here, using the novel technology of integrated positron emission tomography-magnetic resonance imaging and the recently developed radioligand 11C-PBR28, we show increased brain levels of the translocator protein (TSPO), a marker of glial activation, in patients with chronic low back pain. As the Ala147Thr polymorphism in the TSPO gene affects binding affinity for 11C-PBR28, nine patient–control pairs were identified from a larger sample of subjects screened and genotyped, and compared in a matched-pairs design, in which each patient was matched to a TSPO polymorphism-, age- and sex-matched control subject (seven Ala/Ala and two Ala/Thr, five males and four females in each group; median age difference: 1 year; age range: 29–63 for patients and 28–65 for controls). Standardized uptake values normalized to whole brain were significantly higher in patients than controls in multiple brain regions, including thalamus and the putative somatosensory representations of the lumbar spine and leg. The thalamic levels of TSPO were negatively correlated with clinical pain and circulating levels of the proinflammatory citokine interleukin-6, suggesting that TSPO expression exerts pain-protective/anti-inflammatory effects in humans, as predicted by animal studies. Given the putative role of activated glia in the establishment and or maintenance of persistent pain, the present findings offer clinical implications that may serve to guide future studies of the pathophysiology and management of a variety of persistent pain conditions.

    The effective treatment of brain cancer is hindered by the poor transport across the blood-brain barrier (BBB) and the low penetration across the blood-tumor barrier (BTB). The objective of this work was to formulate transferrin-conjugated docetaxel (DTX)-loaded d-alpha-tocopheryl polyethylene glycol 1000 succinate (vitamin E TPGS or TPGS) micelles for targeted brain cancer therapy. The micelles with and without transferrin conjugation were prepared by the solvent casting method and characterized for their particle size, polydispersity, drug encapsulation efficiency, drug loading, in vitro release study and brain distribution study. Particle sizes of prepared micelles were determined at 25 °C by dynamic light scattering technique. The external surface morphology was determined by transmission electron microscopy analysis and atomic force microscopy. The encapsulation efficiency was determined by spectrophotometery. In vitro release studies of micelles and control formulations were carried out by dialysis bag diffusion method. The particle sizes of the non-targeted and targeted micelles were <20 nm. About 85% of drug encapsulation efficiency was achieved with micelles. The drug release from transferrin-conjugated micelles was sustained for >24 h with 50% of drug release. The in vivo results indicated that transferrin-targeted TPGS micelles could be a promising carrier for brain targeting due to nano-sized drug delivery, solubility enhancement and permeability which provided an improved and prolonged brain targeting of DTX in comparison to the non-targeted micelles and marketed formulation.

    Background: Gliomas and neuroblastomas pose a great health burden worldwide with a poor and moderate prognosis, respectively. Many studies have tried to find effective treatments for these primary malignant brain tumors. Of interest, the AMP-activated protein kinase (AMPK) pathway was found to be associated with tumorigenesis and tumor survival, leading to many studies on AMPK drugs, especially Metformin, and their potential role as anti-cancer treatments. Cancer stem cells (CSCs) are a small population of slowly-dividing, treatment-resistant, undifferentiated cancer cells that are being discovered in a multitude of cancers. They are thought to be responsible for replenishing the tumor with highly proliferative cells and increasing the risk of recurrence. Methods: Metformin and 9-β-d-Arabinofuranosyl Adenine (Ara-a) were used to study the role of the AMPK pathway in vitro on U251 (glioblastoma) and SH-SY5Y (neuroblastoma) cell lines. Results: We found that both drugs are able to decrease the survival of U251 and SH-SY5Y cell lines in a 2D as well as a 3D culture model. Metformin and Ara-a significantly decreased the invasive ability of these cancer cell lines. Treatment with these drugs decreased the sphere-forming units (SFU) of U251 cells, with Ara-a being more efficient, signifying the extinction of the CSC population. However, if treatment is withdrawn before all SFUs are extinguished, the CSCs regain some of their sphere-forming capabilities in the case of Metformin but not Ara-a treatment. Conclusion: Metformin and Ara-a have proved to be effective in the treatment of glioblastomas and neuroblastomas, in vitro, by targeting their cancer stem/progenitor cell population, which prevents recurrence.

    Background  Stereotactic irradiation is widely used in brain oligo-metastases treatment. The aim of this study is to evaluate the prognostic value of magnetic resonance imaging (MRI) texture analysis (TA) of brain metastases (BM) of non-small cell lung cancer (NSCLC). Materials and methods  This study included thirty-eight consecutive patients undergoing stereotactic irradiation, that is, stereotactic fractionated radiotherapy (SRT) or radiosurgery (SRS), from January 2011 to December 2014 for 1-2 brain BM from NSCLC. Whole-brain radiotherapy (WBRT) was not delivered. The diagnostic MRI DICOM (Digital Imaging and Communications in Medicine) images were collected and analyzed with a homemade ImageJ macro, and typical TA parameters (mean, standard deviation, skewness, kurtosis, entropy, and uniformity) were evaluated for: brain progression-free survival; modality of brain metastatic progression (local progression or/and new metastases); and overall survival, after SRT/SRS. Results After SRT/SRS 14 patients (36.8%) experienced recurrence in the brain, with a recurrence in the irradiated site (five patients, 13.2%), new metastases (11 patients, 28.9%), local recurrence and new metastases (two patients, 5.25%). Nineteen patients (50%) died of tumor progression or other causes. Entropy and uniformity were significantly associated with local progression, whereas kurtosis was significantly associated with both local progression and new brain metastases. Conclusions  These results appear promising, since the knowledge of factors correlated with the modality of brain progression after stereotactic irradiation of brain oligo-metastatic foci of NSCLC might help in driving the best treatment in these patients (association of SRT/SRS with WBRT? Increase of SRT/SRS dose?). Our preliminary data needs confirmation in large patient series. PMID:27226944

    Purpose Radical radiotherapy for head and neck cancer (HNC) may deliver significant doses to brain structures. There is evidence that this may cause a decline in neurocognitive function (NCF). Radiation dose to the medial temporal lobes, and particularly to the hippocampi, seems to be critical in determining NCF outcomes. We evaluated the feasibility of two alternative intensity-modulated radiotherapy (IMRT) techniques to generate hippocampus- and brain-sparing HNC treatment plans to preserve NCF. Methods and Materials A planning study was undertaken for ten patients with HNC whose planning target volume (PTV) included the nasopharynx. Patients had been previously treated using standard (chemo)-IMRT techniques. Bilateral hippocampi were delineated according to the RTOG atlas, on T1w MRI co-registered to the RT planning CT. Hippocampus-sparing plans (HSRT), and whole-brain/hippocampus-sparing fixed-field non-coplanar IMRT (BSRT) plans, were generated. DVHs and dose difference maps were used to compare plans. NTCP calculations for NCF impairment, based on hippocampal dosimetry, were performed for all plans. Results Significant reductions in hippocampal doses relative to standard plans were achieved in eight of ten cases for both HSRT and BSRT. EQD2 D40% to bilateral hippocampi was significantly reduced from a mean of 23.5 Gy (range 14.5–35.0) in the standard plans to a mean of 8.6 Gy (4.2–24.7) for HSRT (p = 0.001) and a mean of 9.0 Gy (4.3–17.3) for BSRT (p < 0.001). Both HSRT and BSRT resulted in a significant reduction in doses to the whole brain, brain stem, and cerebellum. Conclusion We demonstrate that IMRT plans for HNC involving the nasopharynx can be successfully optimised to significantly reduce dose to the bilateral hippocampi and whole brain. The magnitude of the achievable dose reductions results in significant reductions in the probability of radiation-induced NCF decline. These results could readily be translated into a future clinical trial

    The development of a recommendation was intended for the follow-up of breast cancer patients treated with curative intent in Hungary. Follow-up includes the permanent contact with and health education of the patient, the surveillance and control of the adverse effects of oncological therapies or radiotherapy, the screening of metachron cancers, and the comprehensive (physical, psychological and social) rehabilitation of the patient. The early detection of local/regional tumor relapse is essential with careful follow-up, but there is no need for screening of distant metastases by means of imaging studies or tumor marker tests. If adjuvant endocrine therapy is needed, optimal adherence should be ensured with supportive therapy. In rare cases, special issues such as breast cancer risk/genetic mutation, pregnancy are raised, which should be thoughtfully discussed in view of recent advances in oncology. Follow-up is generally practised by the oncologist, however, in some cases the social worker, the physiotherapist, the psychooncologist, or in special cases, the lymphoedema expert is to be involved. The follow-up approach should be comprehensive and holistic. PMID:27579724

    In any disease, the knowledge of the natural history of untreated cases provides a real background against which the real advantages of a new treatment itself are judged. Fortunately, in the present days, there are scant data on outcomes in patients with untreated breast cancer. In an attempt to provide this background against which the virtues of current curative and palliative treatments can be more accurately assessed, we have reviewed the literature regarding published untreated breast cancer series. Taking into consideration all the difficulties of analyzing reports written on the last half of the nineteenth century or on the first half of the twentieth century, in most reports, patients survived almost 3-4 years without any type of treatment. Worth mentioning, approximately 5-10 % of untreated patients lived longer than 10 years. Thus, the spectrum of clinical aggressiveness of untreated breast cancer varies between virulence and chronic disease. These facts should be taken into account when considering the value of current treatments for early-stage disease. PMID:25588926

    We conducted an exploratory study to investigate which exposures (including poultry oncogenic viruses) are associated with brain cancer in poultry workers. A total of 46,819 workers in poultry and nonpoultry plants from the same union were initially followed for mortality. Brain cancer was observed to be in excess among poultry workers. Here we report on a pilot case-cohort study with cases consisting of 26 (55%) of the 47 brain cancer deaths recorded in the cohort, and controls consisting of a random sample of the cohort (n = 124). Exposure information was obtained from telephone interviews, and brain cancer mortality risk estimated by odds ratios. Increased risk of brain cancer was associated with killing chickens, odds ratio (OR) = 5.8 (95% confidence interval, 1.2-28.3); working in a shell-fish farm, OR = 13.0 (95% CI, 1.9-84.2); and eating uncooked fish, OR = 8.2 (95% CI, 1.8-37.0). Decreased risks were observed for chicken pox illness, OR = 0.2 (95% CI, 0.1-0.6), and measles vaccination, OR = 0.2 (95% CI, 0.1-0.6). Killing chickens, an activity associated with the highest occupational exposure to poultry oncogenic viruses, was associated with brain cancer mortality, as were occupational and dietary shellfish exposures. These findings are novel. PMID:24564367

    Being diagnosed with a metastatic brain tumour can be devastating as it is characterized by very low cure rates, as well as significant morbidity and mortality. Given the poor life expectancy and progressive disability that ensues, patients and family members experience much turmoil, which includes losses that bring about changes to family roles, routines and relationships. Crisis and conflict are common during such major disruptions to a family system, as individual members attempt to make sense of the illness experience based on cultural and spiritual beliefs, past experiences and personal philosophies. It is imperative health care providers strive towards increased awareness and knowledge of how culture affects the overall experience of illness and death in order to help create a mutually satisfactory care plan. Providing culturally-competent care entails the use of proper communication skills to facilitate the exploration of patient and family perspectives and allows for mutual decision making. A case study will illustrate the challenges encountered in providing culturally-competent care to a woman with brain cancer and her family. As the patient's health declined, the family entered into a state of crisis where communication between family members and health care professionals was strained; leading to conflict and sub-optimal outcomes. This paper will address the ethical dilemma of providing culturally-competent care when a patient's safety is at risk, and the nursing implications of upholding best practices in the context of differing beliefs and priorities.

    Background To evaluate risk factors that predict brain metastasis in epithelial ovarian, fallopian tube, and peritoneal cancer. Methods All patients with FIGO stage I to IV who underwent initial cytoreductive surgery between January 1995 and January 2009 were evaluated. The tumor samples were evaluated for 7 markers including multi-drug resistance gene (MDR-1), DNA aneuploidity and S-phase fraction, human epidermal growth factor receptor 2, estrogen receptor, progesterone receptor, p53 mutation, epidermal growth factor receptor, and CD31. Biomarker expression was evaluated as a predictor of hematogenous metastasis to the following locations: (i) liver and spleen, (ii) lung, and (iii) brain. Results There were 309 cases identified during the period. Of those, five (1.6%, 95%CI 0.2-3.0%) women developed brain metastasis. Time to onset of brain metastasis was significantly longer than for other recurrent sites (median time to recurrence after initial cytoreduction, brain vs lung vs liver, 21.4 vs 12.6 vs 11.0 months, p<0.05). Significantly increased expression of MDR-1 was seen in tumors from women who developed brain metastasis (brain vs non-brain sites, 80% vs 4.2-24.3%, p=0.004). In multivariate analysis, MDR-1 was the only significant variable associated with the risk of brain metastasis. MDR-1 expression predicted brain metastasis (Receiver-operator-characteristic curve analysis, AUC 0.808, p=0.018), and with a 10% positive expression of MDR-1 as the cutoff value, sensitivity, specificity, positive predictive value, negative predictive value, accuracy of prediction of brain metastasis were 80%, 86.1%, 15.4%, 99.3%, and 85.9%, respectively (odds ratio 24.7, 95%CI 2.64-232, p=0.002). Conclusions Increased expression of MDR-1 in the tumor tissue obtained at initial cytoreduction is associated with increased risk of developing brain metastases in women with epithelial ovarian, fallopian tube, or peritoneal cancer.

    The aim of the paper is to develop a procedure for an estimate of an analytical form of a hazard function for cancer patients. Although a deterministic approach based on cancer cell population dynamics yields the analytical expression, it depends on several parameters which should be estimated. On the other hand, a kernel estimate is an effective nonparametric method for estimating hazard functions. This method provides the pointwise estimate of the hazard function. Our procedure consists of two steps: in the first step we find the kernel estimate of the hazard function and in the second step the parameters in the deterministic model are obtained by the least squares method. A simulation study with different types of censorship is carried out and the developed procedure is applied to real data. PMID:18634801

    2011-01-01

    Irreversible electroporation (IRE) is a new minimally invasive technique to kill tumors and other undesirable tissue in a non-thermal manner. During an IRE treatment, a series of short and intense electric pulses are delivered to the region of interest to destabilize the cell membranes in the tissue and achieve spontaneous cell death. The alteration of the cellular membrane results in a dramatic increase in electrical conductivity during IRE as in other electroporation-based-therapies. In this study, we performed the planning and execution of an IRE brain cancer treatment using MRI reconstructions of the tumor and a multichannel array that served as a stereotactic fiducial and electrode guide. Using the tumor reconstructions within our numerical simulations, we developed equations relating the increase in tumor conductivity to calculated currents and volumes of tumor treated with IRE. We also correlated the experimental current measured during the procedure to an increase in tumor conductivity ranging between 3.42-3.67 times the baseline conductivity, confirming the physical phenomenon that has been detected in other tissues undergoing similar electroporation-based treatments.

    We aimed to identify the incidence, duration and causes of delayed emergence from anesthesia in patients with dystonia undergoing surgery for deep brain stimulation (DBS) placement. A retrospective review of patients with dystonia who underwent DBS placement was conducted and the following characteristics were noted: age, gender, comorbid conditions, American Society of Anesthesiologists classification, anesthetic agents used, amount of initial dose, amount of infusion dose, duration of the infusion and the time needed for emergence. Twenty-four patients underwent 33 DBS procedures for dystonia. Propofol was administered to 21 patients, in 29 of the 33 procedures. Dexmedetomidine was administered to three patients, in four procedures. The average propofol loading dose was 0.7mg/kg, and the infusion rate was 80microg/kg per minute (min), for an average duration of 89min. The average time of emergence was 36min. Only 31% of patients emerged from propofol anesthesia during the expected time frame, 69% of patients had some degree of delayed emergence, and 24% had a significant delay in emergence. Delayed emergence was more common in younger patients due to the higher loading doses these patients received. This study shows a 69% incidence of delayed emergence in dystonia patients undergoing DBS surgery. It also suggests an association between delayed emergence and younger patients who receive higher loading doses. A possible cause of delayed emergence is excessive anesthetic potentiation of the low output pallidal state in dystonia which may depress the pallido-thalamo-cortical circuitry. Delayed emergence could also result from depression of the previously affected ventral pallidal inputs to the septo-hippocampal system that mediates general anesthesia and awareness. Complex neurotransmitter disturbances may also be involved. PMID:20466547

    Proper selection of patients who will reliably benefit from deep brain stimulation (DBS) is critical to its success. This requires careful evaluation that should be delivered by an expert multidisciplinary team involving a movement disorder neurologist, a neurosurgeon, a neuropsychologist, and a psychiatrist. The most suitable candidates for DBS suffer from Parkinson's disease with motor fluctuations and/or dyskinesias that are not adequately controlled with optimized medical therapy, or with medication-refractory tremor. During the best on-motor periods, gait difficulties, instability, and speech problems should be minimal, reflecting an excellent response to levodopa in the ideal candidate. The cognitive, psychiatric, and behavioral status must be normal or minimally affected, with the exception of dopamine agonist drug-induced impulse control disorders, which are usually improved after successful surgery and drug withdrawal. Moreover, the patients have no serious comorbidities. Most patients corresponding to this profile suffer from a relatively young onset of Parkinson's disease, and are aged less than 70 years at the time of surgery. Indeed, most patients fall outside this ideal description, and the medical art is to appreciate for each patient the extent to which the alterations of these features can be accepted. Eventually, patients make their own decision from detailed information of their individualized risks and benefits of DBS. Patient expectations, cooperation, and familial support are also important considerations. PMID:24112888

    Purpose: Data comparing the clinical outcomes of local brain radiotherapy (LBRT) and whole brain RT (WBRT) in patients with a single brain metastasis after tumor removal are limited. Patients and Methods: A retrospective analysis was performed to compare the patterns of treatment failure, cause of death, progression-free survival, median survival time, and Karnofsky performance status for long-term survivors among patients who underwent surgery followed by either LBRT or WBRT between 1990 and 2008 at the National Cancer Center Hospital. Results: A total of 130 consecutive patients were identified. The median progression-free survival period among the patients who received postoperative LBRT (n = 64) and WBRT (n = 66) was 9.7 and 11.5 months, respectively (p = .75). The local recurrence rates (LBRT, 9.4% vs. WBRT, 12.1%) and intracranial new metastasis rate (LBRT, 42.2% vs. WBRT, 33.3%) were similar in each arm. The incidence of leptomeningeal metastasis was also equivalent (LBRT, 9.4% vs. WBRT, 10.6%). The median survival time for the LBRT and WBRT patients was 13.9 and 16.7 months, respectively (p = .88). A neurologic cause of death was noted in 35.6% of the patients in the LBRT group and 36.7% of the WBRT group (p = .99). The Karnofsky performance status at 2 years was comparable between the two groups. Conclusions: The clinical outcomes of LBRT and WBRT were similar. A prospective evaluation is warranted.

    Life expectancy for patients with breast carcinoma has changed in Europe over the last two decades. In Italy, the overall survival rate is about 77% at 5 years. When considering the situation in Sicily, the EUROCARE 2 study examined survival data from the Ragusa Cancer Registry, showing that the curves are worse than in other regions of Italy. Starting from these considerations we decide to evaluate whether these data from the Ragusa Cancer Registry corresponded to Palermo data. So we analysed data from 575 consecutive patients with breast cancer, treated in our Breast Unit from 1990 to 2003 according to the St. Gallen Recommendations and followed for a median period of 5 years. The prognostic role of age, tumour size, nodal status, TNM, stage, grading and hormonal receptors (OR, PR) were analysed and survival curves at 5 and 10 years were produced using the actuarial survival methods. All causes of death were considered. The median follow-up was 33 months. The Log rank test and univariate cox proportional model were used to demonstrate the association between prognostic factors and outcome. When considering T and N status, the curves showed an inverse correlation between survival and increases in these parameters. Overall survival was 92.9% at 5 years and 81.4% at 10 years for T1, 78.4% at 5 years and 61.4% at 10 years for T2 and 40.8% for T3-T4 at 5 and 10 years. Overall survival for NO was 92.1% and 78.2%, respectively, at 5 and 10 years, but decreased to 72.0% and 59.9% at 5 and 10 years for N1. In N2 patients we found that only about 50% of patients were still alive at 5 and 10 years, while for N3 patients the figures were 57.2% and 40%, respectively. PMID:17663369
