    Early response to chemotherapy has a major prognostic impact in acute myeloid leukemia patients treated with a double induction strategy. Less is known about patients treated with standard-dose cytarabine and anthracycline. We designed a risk-adapted remission induction regimen in which a second course of intermediate-dose cytarabine was delivered after standard "7+3" only if patients had 5% or more bone marrow blasts 15 days after chemotherapy initiation (d15-blasts). Of 823 included patients, 795 (96.6%) were evaluable. Five hundred and forty-five patients (68.6%) had less than 5% d15-blasts. Predictive factors for high d15-blasts were white blood cell count (P<0.0001) and cytogenetic risk (P<0.0001). Patients with fewer than 5% d15-blasts had a higher complete response rate (91.7% vs. 69.2%; P<0.0001) and a lower induction death rate (1.8% vs. 6.8%; P=0.001). Five-year event-free (48.4% vs. 25%; P<0.0001), relapse-free (52.7% vs. 36.9%; P=0.0016) and overall survival (55.3% vs. 36.5%; P<0.0001) were significantly higher in patients with d15-blasts lower than 5%. Multivariate analyses identified d15-blasts and cytogenetic risk as independent prognostic factors for the three end points. Failure to achieve early blast clearance remains a poor prognostic factor even after early salvage. By contrast, early responding patients have a favorable outcome without any additional induction course. (ClinicalTrials.gov identifier NCT01015196). PMID:23975179

    Germ cell tumors present contrasting biological and molecular features compared to many solid tumors, which may partially explain their unusual sensitivity to chemotherapy. Reduced DNA repair capacity and enhanced induction of apoptosis appear to be key factors in the sensitivity of germ cell tumors to cisplatin. Despite substantial cure rates, some patients relapse and subsequently die of their disease. Intensive doses of chemotherapy are used to counter mechanisms of drug resistance. So far, high-dose chemotherapy with hematopoietic stem cell support for solid tumors is used only in the setting of testicular germ cell tumors. In that indication, high-dose chemotherapy is given as the first or late salvage treatment for patients with either relapsed or progressive tumors after initial conventional salvage chemotherapy. High-dose chemotherapy is usually given as two or three sequential cycles using carboplatin and etoposide with or without ifosfamide. The administration of intensive therapy carries significant side effects and can only be efficiently and safely conducted in specialized referral centers to assure optimum patient care outcomes. In breast and ovarian cancer, most studies have demonstrated improvement in progression-free survival (PFS), but overall survival remained unchanged. Therefore, most of these approaches have been dropped. In germ cell tumors, clinical trials are currently investigating novel therapeutic combinations and active treatments. In particular, the integration of targeted therapies constitutes an important area of research for patients with a poor prognosis. PMID:25493378

    Background: Chemotherapy-induced nausea and vomiting are the most important complications for cancer patients as its prevalence has been reported to be about 54-96 percent. ginger has been used for medicinal purposes including nausea and vomiting in traditional Persian, Chinese and Indian pharmacopoeia. Objectives: The objective of this study was to evaluate the efficacy of complimentary ginger among cancer patients experiencing nausea and vomiting. Material and Methods: A randomized cross-over clinical trial was carried out on patients under chemotherapy treatment for at least 2 episodes of chemotherapy and at least 2 episodes of previous experience of nausea and vomiting. Subjects of this study received 2 different complementary regimes with 250mg ginger capsule in regime A and placebo capsule in regime B. subjects of the study were crossed over to receive the other regime during the two cycles of chemotherapy. Results: Findings of the study indicated that subjects receiving ginger showed significant reduction in frequency and intensity of nausea and vomiting compared to placebo receiving subjects. Conclusions: According to finding of this study, in accordance to most of other researches, ginger is an effective agent to reduce chemotherapy-induced nausea and vomiting. However, there are some researches supporting ginger as a moderate antiemetic agent among cancerous patients under chemotherapy. PMID:24693415

    Adults with newly diagnosed or relapsed acute myeloid leukemia (AML) commonly receive intensive chemotherapy to achieve disease remission. In the United States and many other countries, it is standard practice that these patients remain hospitalized "preemptively" until blood count recovery, owing to the risk for overwhelming infections and bleeding during pancytopenia. This care policy requires hospitalization for an average of 3 to 4 weeks after completion of chemotherapy. However, highly effective oral prophylactic antimicrobials are now available, and transfusion support of outpatients has become routine in recent years. As a result, the care of patients with hematologic malignancies treated with intensive modalities is increasingly shifting from inpatient to outpatient settings. Benefits of this shift could include the reduced need for medical resources (eg, transfusions or intravenous antimicrobial therapy), improved quality of life (QOL), decreased rates of nosocomial infections, and lower costs. Increasing evidence indicates that select AML patients undergoing intensive remission induction or salvage chemotherapy can be discharged early after completion of chemotherapy and followed closely in a well-equipped outpatient facility in a safe and costeffective manner. Further demonstration that the current approach of preemptive hospitalization is medically unjustified, economically more burdensome, and adversely affects health-related QOL would very likely change the management of these patients throughout this country and elsewhere, resulting in the establishment of a new standard practice that improves cancer care.

    We assessed the influence of obesity on the characteristics and prognosis of acute myeloid leukemia (AML). Indeed, safety of intensive chemotherapy and outcome of obese AML patients in a real-life setting are poorly described, and chemotherapy dosing remains challenging. We included 619 consecutive genetically-defined cases of AML treated with intensive chemotherapy between 2004 and 2012. In this cohort, 93 patients (15%) were classified in the obese category according to WHO classification; 59% of them received capped doses of chemotherapy because of a body surface area above 2 m(2) . Obese patients were older and presented more often with cardiovascular comorbidities. Although obese patients had more frequently de novo AML, main characteristics of AML including white blood cell count, karyotype and mutations were well-balanced between obese and non-obese patients. After induction chemotherapy, early death and complete remission rates were similar. Overall (OS), event-free (EFS) and disease-free (DFS) survival were not significantly different compared to non-obese patients. However, in the European LeukemiaNet (ELN) favorable subgroup, obese patients had lower median OS, EFS and DFS than non-obese patients (18.4, 16.8 and 17.2 vs. 43.6, 31.8 and 29.7 months, respectively) and obesity showed a significant impact on OS (OR 2.54; P = 0.02) in multivariate models. Although we did not find any significant impact of obesity on outcome in the whole series, this study suggests that special efforts for chemotherapy dose optimization are needed in the ELN favorable subgroup since dose capping may be deleterious.

    Although enteral nutrition is generally advocated in the care of children with cancer, those patients receiving intensive chemotherapy alone or in combination with bone marrow transplantation often require total parenteral nutrition (TPN). Two patients are presented illustrating some differences between enteral and parenteral feedings in children receiving intensive chemotherapy. Nasogastric glutamine-supplemented tube feedings were well tolerated both in the hospital and at home. The cost of care for the enterally supported child was less than one third of the TPN-supported child. Although TPN appears to be beneficial in some patients with cancer, it is expensive and is associated with several significant disadvantages. Among these are an increased incidence of both gram-positive and gram-negative infections and an increased incidence of gastrointestinal symptoms. Enteral nutrition is less costly than TPN and maintains the structural and functional integrity of the intestinal mucosa. The addition of certain substrates such as glutamine, arginine and omega-3 fatty acids may improve the body's immune response as well. We hypothesize that early glutamine supplemented tube feedings in children receiving intensive chemotherapy alone or in combination with bone marrow transplantation will result in improved nutrition with fewer infections and lower cost than TPN-supplemented patients. In addition, a shorter hospital stay and improved quality of life are anticipated. PMID:9144976

    Purpose: The goal of this study was to evaluate dosimetric parameters, acute toxicity, pathologic response, and local control in patients treated with preoperative intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy for localized gastric adenocarcinoma. Methods: Between November 2007 and April 2010, 25 patients with localized gastric adenocarcinoma were treated with induction chemotherapy, followed by preoperative IMRT and concurrent chemotherapy and, finally, surgical resection. The median radiation therapy dose was 45 Gy. Concurrent chemotherapy was 5-fluorouracil and oxaliplatin in 18 patients, capecitabine in 3, and other regimens in 4. Subsequently, resection was performed with total gastrectomy in 13 patients, subtotal gastrectomy in 7, and other surgeries in 5. Results: Target coverage, expressed as the ratio of the minimum dose received by 99% of the planning target volume to the prescribed dose, was a median of 0.97 (range, 0.92-1.01). The median V{sub 30} (percentage of volume receiving at least 30 Gy) for the liver was 26%; the median V{sub 20} (percentage of volume receiving at least 20 Gy) for the right and left kidneys was 14% and 24%, respectively; and the median V{sub 40} (percentage of volume receiving at least 40 Gy) for the heart was 18%. Grade 3 acute toxicity developed in 14 patients (56%), including dehydration in 10, nausea in 8, and anorexia in 5. Grade 4 acute toxicity did not develop in any patient. There were no significant differences in the rates of acute toxicity, hospitalization, or feeding tube use in comparison to those in a group of 50 patients treated with preoperative three-dimensional conformal radiation therapy with concurrent chemotherapy. R0 resection was obtained in 20 patients (80%), and pathologic complete response occurred in 5 (20%). Conclusions: Preoperative IMRT for gastric adenocarcinoma was well tolerated, accomplished excellent target coverage and normal structure sparing, and led to appropriate

    Purpose Fatigue is an important problem in children receiving intensive chemotherapy and hematopoietic stem cell transplantation (HSCT). Exercise may be an effective intervention for fatigue. Individualized yoga represents an ideal intervention because it can be tailored according to an individual child's needs. Little is known about how to structure a standardized yoga program for intensivelytreated children. Therefore, this study describes the development of a yoga program and an approach to monitoring sessions suitable for hospitalized children receiving intensive chemotherapy or HSCT. Methods The yoga program was designed to increase mobility in hospitalized children and to provide children with relaxation techniques that could be used independently in a variety of environments. The program was founded on 4 key tenets: safety, adaptability, environmental flexibility, and appeal to children. We also developed quality and consistency assurance procedures. Results A menu format with a fixed structure was selected for the yoga program. Each yoga session contained up to 6 sections: breathing exercises, warmup exercises, yoga poses, balancing poses, cool-down poses, and final relaxation. Yoga instructors selected specific yoga poses for each session from a predetermined list organized by intensity level (low, moderate, or high). Monitoring procedures were developed using videotaping and multirater adjudication. Conclusion We created a standardized yoga program and an approach to monitoring that are now ready for incorporation in clinical trials. Future work should include the adaptation of the program to different pediatric populations and clinical settings. PMID:27146130

    Malignant rhabdoid tumors (MRT) of soft tissues are aggressive tumors, which can be detected in almost any part of the body. MRT are rare, and very few cases have been reported in the literature. Prognosis of these tumors is extremely poor despite intensive therapy. Some risk factors such as young age or disseminated disease are associated with an aggressive and almost always lethal clinical course. Some clinicians even recommend initial palliative care due to this outcome. We report a case of metastatic MRT in a 6-month-old child with excellent initial response to chemotherapy. PMID:24852450

    Prognosis of Philadelphia-positive (Ph(+)) acute lymphoblastic leukemia (ALL) in the elderly has improved during the imatinib era. We investigated dasatinib, another potent tyrosine kinase inhibitor, in combination with low-intensity chemotherapy. Patients older than age 55 years were included in the European Working Group on Adult ALL (EWALL) study number 01 for Ph(+) ALL (EWALL-PH-01 international study) and were treated with dasatinib 140 mg/day (100 mg/day over 70 years) with intrathecal chemotherapy, vincristine, and dexamethasone during induction. Patients in complete remission continued consolidation with dasatinib, sequentially with cytarabine, asparaginase, and methotrexate for 6 months. Maintenance therapy was dasatinib and vincristine/dexamethasone reinductions for 18 months followed by dasatinib until relapse or death. Seventy-one patients with a median age of 69 years were enrolled; 77% had a high comorbidity score. Complete remission rate was 96% and 65% of patients achieved a 3-log reduction in BCR-ABL1 transcript levels during consolidation. Only 7 patients underwent allogeneic hematopoietic stem cell transplantation. At 5 years, overall survival was 36% and up to 45% taking into account deaths unrelated to disease or treatment as competitors. Thirty-six patients relapsed, 24 were tested for mutation by Sanger sequencing, and 75% were T315I-positive. BCR-ABL1(T315I) was tested by allele-specific oligonucleotide reverse transcription-quantitative polymerase chain reaction in 43 patients and detection was associated with short-term relapses. Ten patients (23%) were positive before any therapy and 8 relapsed, all with this mutation. In conclusion, dasatinib combined with low-intensity chemotherapy was well-tolerated and gave long-term survival in 36% of elderly patients with Ph(+) ALL. Monitoring of BCR-ABL1(T315I) from diagnosis identified patients with at high risk of early relapse and may help to personalize therapy. PMID:27121472

    Purpose: The purpose of this study was to investigate the dose-effect relation between acute esophageal toxicity (AET) and the dose-volume parameters of the esophagus after intensity modulated radiation therapy (IMRT) and concurrent chemotherapy for patients with non-small cell lung cancer (NSCLC). Patients and Methods: One hundred thirty-nine patients with inoperable NSCLC treated with IMRT and concurrent chemotherapy were prospectively analyzed. The fractionation scheme was 66 Gy in 24 fractions. All patients received concurrently a daily dose of cisplatin (6 mg/m Superscript-Two ). Maximum AET was scored according to Common Toxicity Criteria 3.0. Dose-volume parameters V5 to V70, D{sub mean} and D{sub max} of the esophagus were calculated. A logistic regression analysis was performed to analyze the dose-effect relation between these parameters and grade {>=}2 and grade {>=}3 AET. The outcome was compared with the clinically used esophagus V35 prediction model for grade {>=}2 after radical 3-dimensional conformal radiation therapy (3DCRT) treatment. Results: In our patient group, 9% did not experience AET, and 31% experienced grade 1 AET, 38% grade 2 AET, and 22% grade 3 AET. The incidence of grade 2 and grade 3 AET was not different from that in patients treated with CCRT using 3DCRT. The V50 turned out to be the most significant dosimetric predictor for grade {>=}3 AET (P=.012). The derived V50 model was shown to predict grade {>=}2 AET significantly better than the clinical V35 model (P<.001). Conclusions: For NSCLC patients treated with IMRT and concurrent chemotherapy, the V50 was identified as most accurate predictor of grade {>=}3 AET. There was no difference in the incidence of grade {>=}2 AET between 3DCRT and IMRT in patients treated with concurrent chemoradiation therapy.

    Introduction. Cytoreductive surgery (CS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is a new approach for peritoneal carcinomatosis. However, high rates of complications are associated with CS and HIPEC due to treatment complexity; that is why some patients need stabilization and surveillance for complications in the intensive care unit. Objective. This study analyzed that ICU stay is necessary after HIPEC. Methods. 39 patients with peritoneal carcinomatosis were treated according to strict selection criteria with CS and HIPEC, with closed technique, and the chemotherapy administered were cisplatin 25 mg/m2/L and mitomycin C 3.3 mg/m2/L for 90-minutes at 40.5°C. Results. 26 (67%) of the 39 patients were transferred to the ICU. Major postoperative complications were seen in 14/26 patients (53%). The mean time on surgical procedures was 7.06 hours (range 5−9 hours). The mean blood loss was 939 ml (range 100–3700 ml). The mean time stay in the ICU was 2.7 days. Conclusion. CS with HIPEC for the treatment of PC results in low mortality and high morbidity. Therefore, ICU stay directly following HIPEC should not be standardized, but should preferably be based on the extent or resections performed and individual patient characteristics and risk factors. Late complications were comparable to those reported after large abdominal surgery without HIPEC. PMID:24864143

    Despite progress in the understanding of leukemia pathophysiology, the treatment of acute myeloid leukemia (AML) remains challenging. In patients with refractory or relapsed (R/R) AML, the prognosis is still poor and this group is targeted for new drug development. We reviewed the outcome of 47 patients, with R/R AML after at least one course of intensive chemotherapy, treated with 5-azacytidine in three different French institutions. The overall response rate was 38% including complete remission in 21%, partial remission in 11%, and hematological improvement in 6% of cases. Median time to relapse was 6 (range, 1-39) months. Median overall survival was 9 months (not reached by responders vs. 4.5 months for nonresponders patients, P = 0.0001). Univariate analysis identified the absence of peripheral blood blasts and <20% bone marrow blasts as prognostic factors for both overall response and survival, but not age, ECOG/PS, type of AML, cytogenetic, status of the disease, number of previous lines of therapy, previous hematological stem cell transplantation, or white blood cells count. Bone marrow blasts percentage <20% was the only independent prognostic factor identified by multivariate analysis for overall response (P = 0.0013) and survival (P = 0.0324). Six patients in remission could proceed to an allogenic hematological stem cell transplantation. The drug-related grade 3/4 adverse events were hematopoietic toxicities (38%) and infection (32%). In conclusion, this study suggests that a salvage therapy with 5-azacytidine is an interesting option for patients with R/R AML after intensive chemotherapy. Prospective randomized studies are needed to demonstrate a superiority of this approach over others strategies. PMID:23619977

    Hemophagocytic lymphohistiocytosis is a condition of immune dysregulation characterized by severe organ damage induced by a hyperinflammatory response and uncontrolled T-cell and macrophage activation. Secondary hemophagocytic lymphohistiocytosis typically occurs in association with severe infections or malignancies. Patients with acute myeloid leukemia may be prone to develop hemophagocytic lymphohistiocytosis because of an impaired immune response and a high susceptibility to severe infections. In a series of 343 patients treated by intensive chemotherapy over a 5-year period in our center, we identified 32 patients (9.3%) with fever, very high ferritin levels, and marrow hemophagocytosis (i.e. patients with hemophagocytic lymphohistiocytosis). Compared to patients without hemophagocytic lymphohistiocytosis, these 32 patients had hepatomegaly, pulmonary or neurological symptoms, liver abnormalities, lower platelet count and higher levels of C-reactive protein as well as prolonged pancytopenia. A microbial etiology for the hemophagocytosis was documented in 24 patients: 14 bacterial infections, 9 Herpesviridae infections and 11 fungal infections. The treatment of hemophagocytic lymphohistiocytosis consisted of corticosteroids and/or intravenous immunoglobulins along with adapted antimicrobial therapy. Patients with hemophagocytic lymphohistiocytosis had a median overall survival of 14.9 months, which was significantly shorter than that of patients without hemophagocytic lymphohistiocytosis (22.1 months) (P=0.0016). Hemophagocytic lymphohistiocytosis was significantly associated with a higher rate of induction failure, mainly due to deaths in aplasia. Hemophagocytic lymphohistiocytosis can be diagnosed in up to 10% of patients with acute myeloid leukemia undergoing intensive chemotherapy and is associated with early mortality. Fever, very high ferritin levels and marrow hemophagocytosis represent the cornerstone of the diagnosis. Further biological studies are

    Purpose: To evaluate the feasibility of dose-painting intensity-modulated radiation therapy (DP-IMRT) with a hypofractionated regimen to treat nasopharyngeal carcinoma (NPC) with concomitant toxicity reduction. Methods and Materials: From October 2002 through April 2007, 25 newly diagnosed NPC patients were enrolled in a prospective trial. DP-IMRT was prescribed to deliver 70.2 Gy using 2.34-Gy fractions to the gross tumor volume for the primary and nodal sites while simultaneously delivering 54 Gy in 1.8-Gy fractions to regions at risk of microscopic disease. Patients received concurrent and adjuvant platin-based chemotherapy similar to the Intergroup 0099 trial. Results: Patient and disease characteristics are as follows: median age, 46; 44% Asian; 68% male; 76% World Health Organization III; 20% T1, 52% T2, 16% T3, 12% T4; 20% N0, 36% N1, 36% N2, 8% N3. With median follow-up of 33 months, 3-year local control was 91%, regional control was 91%, freedom from distant metastases was 91%, and overall survival was 89%. The average mean dose to each cochlea was 43 Gy. With median audiogram follow-up of 14 months, only one patient had clinically significant (Grade 3) hearing loss. Twelve percent of patients developed temporal lobe necrosis; one patient required surgical resection. Conclusions: Preliminary findings using a hypofractionated DP-IMRT regimen demonstrated that local control, freedom from distant metastases, and overall survival compared favorably with other series of IMRT and chemotherapy. The highly conformal boost to the tumor bed resulted low rates of severe ototoxicity (Grade 3-4). However, the incidence of in-field brain radiation necrosis indicates that 2.34 Gy per fraction is not safe in this setting.

    Purpose: To perform a retrospective review of laryngeal/hypopharyngeal carcinomas treated with concurrent chemotherapy and intensity-modulated radiotherapy (IMRT). Methods and Materials: Between January 2002 and June 2005, 20 laryngeal and 11 hypopharyngeal carcinoma patients underwent IMRT with concurrent platinum-based chemotherapy; most patients had Stage IV disease. The prescription of the planning target volume for gross, high-risk, and low-risk subclinical disease was 70, 59.4, and 54 Gy, respectively. Acute/late toxicities were retrospectively scored using the Common Toxicity Criteria scale. The 2-year local progression-free, regional progression-free, laryngectomy-free, distant metastasis-free, and overall survival rates were calculated using the Kaplan-Meier method. Results: The median follow-up of the living patients was 26 months (range, 17-58 months). The 2-year local progression-free, regional progression-free, laryngectomy-free, distant metastasis-free, and overall survival rate was 86%, 94%, 89%, 92%, and 63%, respectively. Grade 2 mucositis or higher occurred in 48% of patients, and all experienced Grade 2 or higher pharyngitis during treatment. Xerostomia continued to decrease over time from the end of RT, with none complaining of Grade 2 toxicity at this analysis. The 2-year post-treatment percutaneous endoscopic gastrostomy-dependency rate for those with hypopharyngeal and laryngeal tumors was 31% and 15%, respectively. The most severe late complications were laryngeal necrosis, necrotizing fascitis, and a carotid rupture resulting in death 3 weeks after salvage laryngectomy. Conclusion: These preliminary results have shown that IMRT achieved encouraging locoregional control of locoregionally advanced laryngeal and hypopharyngeal carcinomas. Xerostomia improved over time. Pharyngoesophageal stricture with percutaneous endoscopic gastrostomy dependency remains a problem, particularly for patients with hypopharyngeal carcinoma and, to a lesser

    Purpose: To report the incidence of Pediatric Oncology Group (POG) Grade 3 or 4 ototoxicity in a cohort of patients treated with craniospinal irradiation (CSI) followed by posterior fossa (PF) and/or tumor bed (TB) boost using intensity-modulated radiation therapy (IMRT). Methods and Materials: From 1998 to 2006, 44 patients with medulloblastoma were treated with CSI followed by IMRT to the PF and/or TB and cisplatin-based chemotherapy. Patients with standard-risk disease were treated with 18 to 23.4 Gy CSI followed by either a (1) PF boost to 36 Gy and TB boost to 54 to 55.8 Gy or (2) TB boost to 55.8 Gy. Patients with high-risk disease received 36 to 39.6 Gy CSI followed by a (1) PF boost to 54 to 55.8 Gy, (2) PF boost to 45 Gy and TB boost to 55.8 Gy, or (3) TB boost to 55.8 Gy. Median audiogram follow-up was 41 months (range, 11-92.4 months). Results: POG Grade Ototoxicity 0, 1, 2, 3. and 4 was found in 29, 32, 11, 13. and 3 ears. respectively, with POG Grade 3 or 4 accounting for 18.2% of cases. There was a statistically significant difference in mean radiation dose (D{sub mean}) cochlea according to degree of ototoxicity, with D{sub mean} cochlea increasing with severity of hearing loss (p = 0.027). Conclusions: Severe ototoxicity was seen in 18.2% of ears in children treated with IMRT boost and cisplatin-based chemotherapy. Increasing dose to the cochlea was associated with increasing severity of hearing loss.

    Purpose Concerns regarding neurocognitive toxicity of whole-brain radiotherapy (WBRT) have motivated development of alternative, dose-intensive chemotherapeutic strategies as consolidation in primary CNS lymphoma (PCNSL). We performed a multicenter study of high-dose consolidation, without WBRT, in PCNSL. Objectives were to determine: one, rate of complete response (CR) after remission induction therapy with methotrexate, temozolomide, and rituximab (MT-R); two, feasibility of a two-step approach using high-dose consolidation with etoposide plus cytarabine (EA); three, progression-free survival (PFS); and four, correlation between clinical and molecular prognostic factors and outcome. Patients and Methods Forty-four patients with newly diagnosed PCNSL were treated with induction MT-R, and patients who achieved CR received EA consolidation. We performed a prospective analysis of molecular prognostic biomarkers in PCNSL in the setting of a clinical trial. Results The rate of CR to MT-R was 66%. The overall 2-year PFS was 0.57, with median follow-up of 4.9 years. The 2-year time to progression was 0.59, and for patients who completed consolidation, it was 0.77. Patients age > 60 years did as well as younger patients, and the most significant clinical prognostic variable was treatment delay. High BCL6 expression correlated with shorter survival. Conclusion CALGB 50202 demonstrates for the first time to our knowledge that dose-intensive consolidation for PCNSL is feasible in the multicenter setting and yields rates of PFS and OS at least comparable to those of regimens involving WBRT. On the basis of these encouraging results, an intergroup study has been activated comparing EA consolidation with myeloablative chemotherapy in this randomized trial in PCNSL, in which neither arm involves WBRT.

    Purpose: To analyze the recent single-institution experience of patients with salivary gland tumors who had undergone adjuvant intensity-modulated radiotherapy (IMRT), with or without concurrent chemotherapy. Patients and Methods: We performed a retrospective analysis of 35 salivary gland carcinoma patients treated primarily at the Dana-Farber Cancer Institute between 2005 and 2010 with surgery and adjuvant IMRT. The primary endpoints were local control, progression-free survival, and overall survival. The secondary endpoints were acute and chronic toxicity. The median follow-up was 2.3 years (interquartile range, 1.2-2.8) among the surviving patients. Results: The histologic types included adenoid cystic carcinoma in 15 (43%), mucoepidermoid carcinoma in 6 (17%), adenocarcinoma in 3 (9%), acinic cell carcinoma in 3 (9%), and other in 8 (23%). The primary sites were the parotid gland in 17 (49%), submandibular glands in 6 (17%), tongue in 4 (11%), palate in 4 (11%), and other in 4 (11%). The median radiation dose was 66 Gy, and 22 patients (63%) received CRT. The most common chemotherapy regimen was carboplatin and paclitaxel (n = 14, 64%). A trend was seen for patients undergoing CRT to have more adverse prognostic factors, including Stage T3-T4 disease (CRT, n = 12, 55% vs. n = 4, 31%, p = .29), nodal positivity (CRT, n = 8, 36% vs. n = 1, 8%, p = .10), and positive margins (n = 13, 59% vs. n = 5, 38%, p = .30). One patient who had undergone CRT developed an in-field recurrence, resulting in an overall actuarial 3-year local control rate of 92%. Five patients (14%) developed distant metastases (1 who had undergone IMRT only and 4 who had undergone CRT). Acute Grade 3 mucositis, esophagitis, and dermatitis occurred in 8%, 8%, and 8% (1 each) of IMRT patients and in 18%, 5%, and 14% (4, 1, and 3 patients) of the CRT group, respectively. No acute Grade 4 toxicity occurred. The most common late toxicity was Grade 1 xerostomia (n = 8, 23%). Conclusions: Treatment of

    We assessed in a French regional healthcare network the distribution of treatments, prognostic factors, and outcome of 334 newly diagnosed acute myeloid leukemia patients aged 60 years or older over a 4-year period of time (2007-2010). Patients were selected in daily practice for intensive chemotherapy (n = 115), azacitidine (n = 95), or best supportive care (n = 124). In these three groups, median overall survival was 18.9, 11.3, and 1.8 months, respectively. In the azacitidine group, multivariate analysis showed that overall survival was negatively impacted by higher age (P = 0.010 for one unit increase), unfavorable cytogenetics (P = 0.001), lymphocyte count <0.5 G/L (P = 0.015), and higher lactate dehydrogenase level (P = 0.005 for one unit increase). We compared the survival of patients treated by azacitidine versus intensive chemotherapy and best supportive care using time-dependent analysis and propensity score matching. Patients treated by intensive chemotherapy had a better overall survival compared with those treated by azacitidine from 6 months after diagnosis, whereas patients treated by azacitidine had a better overall survival compared with those treated by best supportive care from 1 day after diagnosis. This study of "real life" practice shows that there is a room for low intensive therapies such as azacitidine in selected elderly acute myeloid leukemia patients. PMID:25195872

    BACKGROUND The clinical benefit of routine placement of prophylactic percutaneous endoscopic gastrostomy (pPEG) tubes was assessed in patients with oropharyngeal cancer (OPC) who are undergoing intensity-modulated radiotherapy (IMRT) with concurrent chemotherapy. METHODS From 1998 through 2009, 400 consecutive patients with OPC who underwent chemoradiation were included. Of these, 325 had a pPEG and 75 did not (nPEG). Weight and albumin change from baseline to mid-IMRT, end of IMRT, 1 month post-IMRT, and 3 months post-IMRT were evaluated. The treating physicians prospectively recorded acute and late toxicities. RESULTS Significantly lower absolute weight loss at end of IMRT (6.80 kg vs 8.38 kg, P = .007), 1 month post-IMRT (9.06 kg vs 11.33 kg, P = .006), and 3 months post-IMRT (11.10 kg vs 13.09 kg, P = .044) was noted in the pPEG versus nPEG groups. This benefit in reduction of percent weight loss was consistently significant only among patients with BMI < 25. Significant differences were noted in hospital admission rate (15.1% vs 26.7%, P = .026) and volume of nonchemotherapy hydration (8.9 liters vs 17.2 liters, P = .004). There were no differences in percent albumin change, acute dysphagia, acute mucositis, acute xerostomia, chronic dysphagia, radiation treatment duration, and overall survival. Multivariate analysis noted age >55 years (P < .001), female sex (P < .001), and T3/4 category disease (P < .001) were significantly associated with prolonged PEG use. CONCLUSIONS Although pPEG reduced absolute and percent weight loss and need for hospitalizations in our cohort of patients with OPC undergoing chemoradiation, no differences were noted in radiation treatment duration, toxicity, and overall survival. Prolonged PEG use correlated with age >55 years, female sex, and T3/T4 tumors. PMID:22707358

    Purpose: To assess the feasibility and toxicity of consolidative intensity-modulated whole abdominal radiotherapy (WAR) after surgery and chemotherapy in high-risk patients with advanced ovarian cancer. Methods and Materials: Ten patients with optimally debulked ovarian cancer International Federation of Gynecology and Obstetrics Stage IIIc were treated in a Phase I study with intensity-modulated WAR up to a total dose of 30 Gy in 1.5-Gy fractions as consolidation therapy after adjuvant carboplatin/taxane chemotherapy. Treatment was delivered using intensity-modulated radiotherapy in a step-and-shoot technique (n = 3) or a helical tomotherapy technique (n = 7). The planning target volume included the entire peritoneal cavity and the pelvic and para-aortal node regions. Organs at risk were kidneys, liver, heart, vertebral bodies, and pelvic bones. Results: Intensity-modulated WAR resulted in an excellent coverage of the planning target volume and an effective sparing of the organs at risk. The treatment was well tolerated, and no severe Grade 4 acute side effects occurred. Common Toxicity Criteria Grade III toxicities were as follows: diarrhea (n = 1), thrombocytopenia (n = 1), and leukopenia (n = 3). Radiotherapy could be completed by all the patients without any toxicity-related interruption. Median follow-up was 23 months, and 4 patients had tumor recurrence (intraperitoneal progression, n = 3; hepatic metastasis, n = 1). Small bowel obstruction caused by adhesions occurred in 3 patients. Conclusions: The results of this Phase I study showed for the first time, to our knowledge, the clinical feasibility of intensity-modulated whole abdominal radiotherapy, which could offer a new therapeutic option for consolidation treatment of advanced ovarian carcinoma after adjuvant chemotherapy in selected subgroups of patients. We initiated a Phase II study to further evaluate the toxicity of this intensive multimodal treatment.

    Background: Nausea and vomiting are the worst and the most prevalent complications experienced by 70–80% of patients. Complementary treatments including therapeutic touch are cost-effective and low-risk, independent nursing interventions. Present research aims at investigating the effect of therapeutic touch on the intensity of acute chemotherapy-induced vomiting in these patients. Materials and Methods: As a single-blind, randomized clinical trial, the present research was carried out on women with breast cancer undergoing chemotherapy in Isfahan, Iran. The subjects were divided into three groups of control, placebo, and intervention. The intervention was applied to each patient once for 20 min on the aura (human energy field) focusing on solar chakra. Data gathering instruments included demographic questionnaire and acute vomiting intensity scale. Results: There was a significant difference among the three groups (and also after the intervention) (P < 0.0001). Paired comparisons among the groups using Mann–Whitney test showed that there was a statistically significant difference between the control group and the intervention group and between the control group and the placebo group (P < 0.0001). However, there was no significant difference between the placebo and intervention groups (P = 0.07). Conclusions: Therapeutic touch was effective in reducing vomiting in the intervention group. However, the patients experienced lower-intensity vomiting which may be because of presence of a therapist and probably the reduced anxiety related to an additional intervention. So, further research is recommended considering the placebo group and employing another person in addition to the therapist, who is not skilled for this technique. PMID:27186202

    Few published studies characterize early lymphocyte recovery after intensive chemotherapy for acute myelogenous leukemia (AML). To test the hypothesis that lymphocyte recovery mirrors ontogeny, we characterized early lymphocyte recovery in 20 consecutive patients undergoing induction timed sequential chemotherapy for newly diagnosed AML. Recovering T lymphocytes were predominantly CD4+ and included a greatly expanded population of CD3+CD4+CD25+Foxp3+ T cells. Recovering CD3+CD4+CD25+Foxp3+ T cells were phenotypically activated regulatory T cells and showed suppressive activity on cytokine production in a mixed lymphocyte reaction. Despite an initial burst of thymopoiesis, most recovering regulatory T cells were peripherally derived. Furthermore, regulatory T cells showed marked oligoclonal skewing, suggesting that their peripheral expansion was antigen-driven. Overall, lymphocyte recovery after chemotherapy differs from ontogeny, specifically identifying a peripherally expanded oligoclonal population of activated regulatory T lymphocytes. These differences suggest a stereotyped immunologic recovery shared by patients with newly diagnosed AML after induction timed sequential chemotherapy. Further insight into this oligoclonal regulatory T-cell population will be fundamental toward developing effective immunomodulatory techniques to improve survival for patients with AML.

    The purpose of this study was to create a prognostic model for distant metastasis in patients with locally advanced NPC who accept concurrent chemotherapy combined with intensity-modulated radiotherapy (CCRT) to identify high-risk patients who may benefit from neoadjuvant chemotherapy (NACT). A total of 881 patients with newly-diagnosed, non-disseminated, biopsy-proven locoregionally advanced NPC were retrospectively reviewed; 411 (46.7%) accepted CCRT and 470 (53.3%) accepted NACT followed by CCRT. Multivariate analysis demonstrated N2–3 disease, plasma Epstein–Barr virus (EBV) DNA > 4000 copies/mL, serum albumin ≤46 g/L and platelet count >300 k/cc were independent prognostic factors for distant metastasis in the CCRT group. Using these four factors, a prognostic model was developed, as follows: 1) low-risk group: 0–1 risk factors; and 2) high-risk group: 2–4 risk factors. In the high-risk group, patients who accepted NACT + CCRT had significantly higher distant metastasis-free survival and progression-free survival rates than the CCRT group (P = 0.001; P = 0.011). This simple prognostic model for distant metastasis in locoregionally advanced NPC may facilitate with the selection of high-risk patients who may benefit from NACT prior to CCRT. PMID:26564805

    Purpose: Limiting the neurocognitive sequelae of radiotherapy (RT) has been an objective in the treatment of medulloblastoma. Conformal RT to less than the entire posterior fossa (PF) after craniospinal irradiation might reduce neurocognitive sequelae and requires evaluation. Methods and Materials: Between October 1996 and August 2003, 86 patients, 3-21 years of age, with newly diagnosed, average-risk medulloblastoma were treated in a prospective, institutional review board-approved, multi-institution trial of risk-adapted RT and dose-intensive chemotherapy. RT began within 28 days of definitive surgery and consisted of craniospinal irradiation (23.4 Gy), conformal PF RT (36.0 Gy), and primary site RT (55.8 Gy). The planning target volume for the primary site included the postoperative tumor bed surrounded by an anatomically confined margin of 2 cm that was then expanded with a geometric margin of 0.3-0.5 cm. Chemotherapy was initiated 6 weeks after RT and included four cycles of high-dose cyclophosphamide, cisplatin, and vincristine. Results: At a median follow-up of 61.2 months (range, 5.2-115.0 months), the estimated 5-year event-free survival and cumulative incidence of PF failure rate was 83.0% {+-} 5.3% and 4.9% {+-} 2.4% ({+-} standard error), respectively. The targeting guidelines used in this study resulted in a mean reduction of 13% in the volume of the PF receiving doses >55 Gy compared with conventionally planned RT. The reductions in the dose to the temporal lobes, cochleae, and hypothalamus were statistically significant. Conclusion: This prospective trial has demonstrated that irradiation of less than the entire PF after 23.4 Gy craniospinal irradiation for average-risk medulloblastoma results in disease control comparable to that after treatment of the entire PF.

    Purpose: To examine clinical outcomes and relapse patterns in locally advanced vulvar carcinoma treated using preoperative chemotherapy and intensity modulated radiation therapy (IMRT). Methods and Materials: Forty-two patients with stage I-IV{sub A} (stage I, n=3; stage II, n=13; stage III, n=23; stage IV{sub A}, n=3) vulvar cancer were treated with chemotherapy and IMRT via a modified Gynecological Oncology Group schema using 5-fluorouracil and cisplatin with twice-daily IMRT during the first and last weeks of treatment or weekly cisplatin with daily radiation therapy. Median dose of radiation was 46.4 Gy. Results: Thirty-three patients (78.6%) had surgery for resection of vulva; 13 of these patients also had inguinal lymph node dissection. Complete pathologic response was seen in 48.5% (n=16) of these patients. Of these, 15 had no recurrence at a median time of 26.5 months. Of the 17 patients with partial pathological response, 8 (47.1%) developed recurrence in the vulvar surgical site within a median of 8 (range, 5-34) months. No patient had grade ≥3 chronic gastrointestinal/genitourinary toxicity. Of those having surgery, 8 (24.2%) developed wound infections requiring debridement. Conclusions: Preoperative chemotherapy/IMRT was well tolerated, with good pathologic response and clinical outcome. The most common pattern of recurrence was local in patients with partial response, and strategies to increase pathologic response rate with increasing dose or adding different chemotherapy need to be explored to help further improve outcomes.

    Adrenocortical carcinoma (ACC) in childhood is a rare tumor with high fatality rate. Available reports provide event free survival rates ranging between 10 to 50%. Optimal treatment has not yet been established; surgery plays a major role, and the value of adjuvant chemotherapy needs to be evaluated further, especially in children who develop recurrent disease and those with metastases at diagnosis. Optimal therapy of ACC has not been established. Surgery has been curative after complete tumor resection. Children with inoperable, recurrent and metastatic ACC have been treated with O,P'DDD, with response rates ranging from 10 to 60% in different series [7,11-20]. Radiotherapy [21] and other anti-cancer drugs have been used [4-22] but their efficacy has not been established. Combination chemotherapy containing oncovin, cisPlatinum, epipodophyllotoxin and cyclophosphamide (OPEC) produced regression of metastatic ACC in a 5-year-old male [23]. We report one girl with relapsed disseminated ACC who showed good, even if temporary, control of the disease, with disappearance of lung, liver and spleen metastases, and marked reduction of the adrenal mass, following combined chemotherapy according to the "eight-drugs-in-one-day" protocol.

    Objective To investigate whether high-intensity focused ultrasound (HIFU) combined with microbubbles enhances the therapeutic effects of chemotherapy. Materials and Methods A pancreatic cancer xenograft model was established using BALB/c nude mice and luciferase-expressing human pancreatic cancer cells. Mice were randomly assigned to five groups according to treatment: control (n = 10), gemcitabine alone (GEM; n = 12), HIFU with microbubbles (HIFU + MB, n = 11), combined HIFU and gemcitabine (HIGEM; n = 12), and HIGEM + MB (n = 13). After three weekly treatments, apoptosis rates were evaluated using the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling assay in two mice per group. Tumor volume and bioluminescence were monitored using high-resolution 3D ultrasound imaging and in vivo bioluminescence imaging for eight weeks in the remaining mice. Results The HIGEM + MB group showed significantly higher apoptosis rates than the other groups (p < 0.05) and exhibited the slowest tumor growth. From week 5, the tumor-volume-ratio relative to the baseline tumor volume was significantly lower in the HIGEM + MB group than in the control, GEM, and HIFU + MB groups (p < 0.05). Despite visible distinction, the HIGEM and HIGEM + MB groups showed no significant differences. Conclusion High-intensity focused ultrasound combined with microbubbles enhances the therapeutic effects of gemcitabine chemotherapy in a pancreatic cancer xenograft model. PMID:27587968

    Purpose To establish accurate prognostic score models to predict survival for patients with nasopharyngeal carcinoma (NPC), treated with intensity-modulated radiotherapy (IMRT) and chemotherapy. Materials and methods Six hundred and seventy-five patients with newly diagnosed, nonmetastatic and histologically proven NPC who were treated with IMRT and chemotherapy were analyzed retrospectively. Samples were split randomly into a training set (n = 338) and a test set (n = 337) to analyze. All data from the training set were used to perform an extensive survival analysis and to develop multivariate nomograms based on Cox regression. Data from the test set was used as an external validation set. Risk group stratification was proposed for the nomograms. Results The nomograms are able to predict survival with a C-index for external validation of local recurrence-free survival (LRFS; 0.66, 95% CI: 0.58-0.74), distant metastasis-free survival (DMFS; 0.73, 95% CI: 0.66-0.79), and disease-specific survival (DSS; 0.73, 95% CI: 0.67-0.79). The calibration curve for probability of survival showed good agreement between prediction by nomogram and actual observation. The C-index of the nomogram for LRFS, DMFS and DSS were statistically higher than the C-index values of the AJCC seventh edition (P < 0.001). In the test set, the nomogram discrimination was also superior to the AJCC Staging systems (P < 0.001). The stratification in risk groups allows significant distinction between Kaplan-Meier curves for outcome. Conclusions Prognostic score models were successfully established and validated to predict LRFS, DMFS, and DSS over a 5-year period after IMRT and chemotherapy, which will be useful for individual treatment.

    In order to investigate the clinical value of different chemotherapies, the efficacy of intensity-modulated radiation therapy with concurrent chemotherapy following D2 radical surgery for gastric carcinoma was evaluated in this study. A total of 102 patients who underwent D2 radical surgery for gastric carcinoma followed by concurrent chemoradiotherapy (CRT) between January, 2008 and March, 2012, were selected. The 5/7 field intensity-modulated radiation therapy was used, with a planning target volume dose of 45 Gy in 25 fractions over 5 weeks. Among these patients, 45 were administered 400 mg/m2/day fluorouracil and 20 mg/m2/day tetrahydrofurfuryl alcohol through intravenous infusion 4 days before and 3 days after the radiotherapy (F-CRT group), while 57 patients received 825 mg/m2 capecitabine orally twice a day (C-CRT group). The 3-year overall and the disease-free survival rates were 75.5 and 70.5%, respectively. The overall 3-year survival rates of the F-CRT and C-CRT groups were 72.2 and 78.5% (P>0.05), respectively, and the 3-year disease-free survival rates were 67.7 and 72.8% (P>0.05), respectively. No significant differences were observed between the two groups. However, during the concurrent CRT, significant differences were found in the incidence of grade 1–2 haematological toxicity between the F-CRT and C-CRT groups (73.3 vs. 50.9%, respectively; χ2 =5.320, P=0.021). Significant differences were also found in the incidence of grade 1–2 gastrointestinal reactions between the two groups (77.8 vs. 57.9%, respectively; χ2=4.474, P=0.034). Therefore, intensity-modulated radiation therapy combined with concurrent chemotherapy following D2 radical surgery for gastric cancer was found to be safe and effective. In addition, radiotherapy was better tolerated and more likely to be completed using C-CRT rather than F-CRT. PMID:27123273

    Purpose: The optimal therapy for primary mediastinal large B-cell lymphoma (PMLBCL) remains undefined. The superiority of intensive chemotherapy regimens (Methotrexate, Doxorubicin, Cyclophosphamide, Vincristine, Prednisone, Bleomycin [MACOP-B]/Etoposide, Doxorubicin, Cyclophosphamide, Vincristine, Prednisone, Bleomycin [VACOP-B]) over Cyclophosphamide, Doxorubicin, Vincristine, Prednisone (CHOP)-like chemotherapy is upheld by some authors. The role of radiotherapy is still debated. In the absence of randomized trials, we report clinical findings and treatment response in 53 consecutive patients treated with intensive chemotherapy and mediastinal involved-field radiation therapy (IFRT). Methods and Material: Fifty-three consecutive patients with PMLBCL were retrospectively analyzed. Planned treatment consisted of induction chemotherapy (I-CT; Prednisone, Methotrexate, Doxorubicin, Cyclophosphamide, Etoposide-Mechloroethamine, Vincristine, Procarbazine, Prednisone [ProMACE-MOPP] in the first 2 patients, MACOP-B in the next 11, and VACOP-B in the last 40) followed by IFRT. Planned treatment was concluded in 43 of 53 patients; in 10 patients, I-CT was not immediately followed by IFRT. Among these 10 patients, 6 received high-dose chemotherapy (HD-CT) followed by IFRT, 2 received HD-CT, and 2 received no further treatment. Results: After a median follow-up of 93.9 months (range, 6-195 months), 45 of 53 patients (84.9%) were alive without disease. Eight patients died: 7 of PMLBCL and 1 of toxicity during HD-CT. The 5-year disease-free survival (DFS) and overall survival rates were 93.42% and 86.6%, respectively. The response rates after I-CT were complete response (CR) in 20 (37.73%) and partial response (PR) in 30 (56.60%); 3 patients (5.66%) were considered nonresponders. Among patients in PR after chemotherapy, 92% obtained a CR after IFRT. Conclusions: Our report confirms the efficacy of intensive chemotherapy plus mediastinal IFRT. IFRT plays a pivotal role in

    Forty-four infants with acute lymphoblastic leukemia (ALL) characterized by MLL gene rearrangements were treated on a protocol of intensive chemotherapy followed by hematopoietic stem cell transplantation (HSCT) between November 1998 and June 2002. The remission induction rate was 91.0%, and the 3-year overall survival and event-free survival (EFS) rates, with 95% confidence intervals, were 58.2% (43.5%-72.9%) and 43.6% (28.5%-58.7%), respectively. Univariate analysis of EFS by presenting features indicated a poorer outcome in patients younger than 6 months of age with high white blood cell counts (>/= 100 x 10(9)/L; EFS rate, 9.4% versus 55.1% for all others, P = .0036) and in those with central nervous system invasion (EFS rate, 10.0% versus 56.9% for all others, P = .0073). The 3-year posttransplantation EFS rate for the 29 patients who underwent HSCT in first remission was 64.4% (46.4%-82.4%). In this subgroup, only the timing of HSCT (first remission versus others) was a significant risk factor by multivariate analysis (P < .0001). These results suggest that early introduction of HSCT, possibly with a less toxic conditioning regimen, may improve the prognosis for infants with MLL(+) ALL. Identification of subgroups or patients who respond well to intensified chemotherapy alone should have a high priority in future investigations. PMID:15297313

  17. Azacitidine might be beneficial in a subgroup of older AML patients compared to intensive chemotherapy: a single centre retrospective study of 227 consecutive patients

    2013-01-01

    Background Treatment options in older acute myeloid leukaemia (AML) patients include intensive chemotherapy, best supportive care (BSC), and hypomethylating agents. Currently, limited data is available on hypomethylating agents in older AML patients in unselected patient populations. Methods To compare the effectiveness of azacitidine with conventional therapy, we collected data of 227 consecutive AML patients (≥60 years) who were treated with azacitidine (N = 26), intensive chemotherapy (N = 90), or BSC (N = 97). Results Azacitidine-treated patients were older and had more comorbidities, but lower white blood cell- and bone marrow blast counts compared with intensive chemotherapy patients. Complete or partial response was achieved in 42% of azacitidine-treated patients and in 73% of intensive chemotherapy patients (P = 0.005). However, the overall survival (OS) was similar (1-year-OS 57% versus 56%, P = 0.93; 2-year-OS 35% versus 35%, P = 0.92), and remained similar after correction for risk factors in a multivariate analysis. Patients treated with BSC had an inferior OS (1-year- and 2-year-OS 16% and 2%, P < 0.001). Compared to intensive chemotherapy, azacitidine-treated patients spent less days in the hospital (median in first three months 0.5 versus 56, P < 0.001), and needed less red blood cell and platelet transfusions (median per month 2.7 versus 7, P < 0.001 and 0.3 versus 5, P < 0.001) in the first three months. Conclusions Azacitidine treatment is associated with a comparable OS but higher tolerability in a subgroup of older AML patients compared with intensive chemotherapy. Patients receiving BSC had a poor prognosis. PMID:23587459

    Purpose: To define the roles of radiotherapy and chemotherapy on the risk of Grade 3+ mucositis during intensity-modulated radiation therapy (IMRT) for oropharyngeal cancer. Methods and Materials: 164 consecutive patients treated with IMRT at two institutions in nonoverlapping treatment eras were selected. All patients were treated with a dose painting approach, three dose levels, and comprehensive bilateral neck treatment under the supervision of the same radiation oncologist. Ninety-three patients received concomitant chemotherapy (cCHT) and 14 received induction chemotherapy (iCHT). Individual information of the dose received by the oral mucosa (OM) was extracted as absolute cumulative dose-volume histogram (DVH), corrected for the elapsed treatment days and reported as weekly (w) DVH. Patients were seen weekly during treatment, and peak acute toxicity equal to or greater than confluent mucositis at any point during the course of IMRT was considered the endpoint. Results: Overall, 129 patients (78.7%) reached the endpoint. The regions that best discriminated between patients with/without Grade 3+ mucositis were found at 10.1 Gy/w (V10.1) and 21 cc (D21), along the x-axis and y-axis of the OM-wDVH, respectively. On multivariate analysis, D21 (odds ratio [OR] = 1.016, 95% confidence interval [CI], 1.009-1.023, p < 0.001) and cCHT (OR = 4.118, 95% CI, 1.659-10.217, p = 0.002) were the only independent predictors. However, V10.1 and D21 were highly correlated (rho = 0.954, p < 0.001) and mutually interchangeable. cCHT would correspond to 88.4 cGy/w to at least 21 cc of OM. Conclusions: Radiotherapy and chemotherapy act independently in determining acute mucosal toxicity; cCHT increases the risk of mucosal Grade 3 toxicity Almost-Equal-To 4 times over radiation therapy alone, and it is equivalent to an extra Almost-Equal-To 6.2 Gy to 21 cc of OM over a 7-week course.

    In this study, we randomly compared high doses of the tyrosine kinase inhibitor imatinib combined with reduced-intensity chemotherapy (arm A) to standard imatinib/hyperCVAD (cyclophosphamide/vincristine/doxorubicin/dexamethasone) therapy (arm B) in 268 adults (median age, 47 years) with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). The primary objective was the major molecular response (MMolR) rate after cycle 2, patients being then eligible for allogeneic stem cell transplantation (SCT) if they had a donor, or autologous SCT if in MMolR and no donor. With fewer induction deaths, the complete remission (CR) rate was higher in arm A than in arm B (98% vs 91%; P = .006), whereas the MMolR rate was similar in both arms (66% vs 64%). With a median follow-up of 4.8 years, 5-year event-free survival and overall survival (OS) rates were estimated at 37.1% and 45.6%, respectively, without difference between the arms. Allogeneic transplantation was associated with a significant benefit in relapse-free survival (hazard ratio [HR], 0.69; P = .036) and OS (HR, 0.64; P = .02), with initial white blood cell count being the only factor significantly interacting with this SCT effect. In patients achieving MMolR, outcome was similar after autologous and allogeneic transplantation. This study validates an induction regimen combining reduced-intensity chemotherapy and imatinib in Ph+ ALL adult patients and suggests that SCT in first CR is still a good option for Ph+ ALL adult patients. This trial was registered at www.clinicaltrials.gov as #NCT00327678. PMID:25878120

    The widespread use of multiplex molecular diagnostics has led to a significant increase in the detection of respiratory viruses in patients undergoing cytotoxic chemotherapy and hematopoietic cell transplantation (HCT). Respiratory viruses initially infect the upper respiratory tract and then progress to lower respiratory tract disease in a subset of patients. Lower respiratory tract disease can manifest itself as airflow obstruction or viral pneumonia, which can be fatal. Infection in HCT candidates may require delay of transplantation. The risk of progression differs between viruses and immunosuppressive regimens. Risk factors for progression and severity scores have been described, which may allow targeting treatment to high-risk patients. Ribavirin is the only antiviral treatment option for noninfluenza respiratory viruses; however, high-quality data demonstrating its efficacy and relative advantages of the aerosolized versus oral form are lacking. There are significant unmet needs, including data defining the virologic characteristics and clinical significance of human rhinoviruses, human coronaviruses, human metapneumovirus, and human bocavirus, as well as the need for new treatment and preventative options.

    DNA methylation changes are a constant feature of acute myeloid leukemia. Hypomethylating drugs such as azacitidine are active in acute myeloid leukemia (AML) as monotherapy. Azacitidine monotherapy is not curative. The AML-AZA trial tested the hypothesis that DNA methyltransferase inhibitors such as azacitidine can improve chemotherapy outcome in AML. This randomized, controlled trial compared the efficacy of azacitidine applied before each cycle of intensive chemotherapy with chemotherapy alone in older patients with untreated AML. Event-free survival (EFS) was the primary end point. In total, 214 patients with a median age of 70 years were randomized to azacitidine/chemotherapy (arm-A) or chemotherapy (arm-B). More arm-A patients (39/105; 37%) than arm-B (25/109; 23%) showed adverse cytogenetics (P=0.057). Adverse events were more frequent in arm-A (15.44) versus 13.52 in arm-B, (P=0.26), but early death rates did not differ significantly (30-day mortality: 6% versus 5%, P=0.76). Median EFS was 6 months in both arms (P=0.96). Median overall survival was 15 months for patients in arm-A compared with 21 months in arm-B (P=0.35). Azacitidine added to standard chemotherapy increases toxicity in older patients with AML, but provides no additional benefit for unselected patients. PMID:26522083

    In our previous in vitro trials, decitabine and all-trans retinoic acid (ATRA) demonstrated synergistic effects on growth inhibition, differentiation, and apoptosis in SHI-1 cells; in K562 cells, ATRA enhanced the effect of decitabine on p16 demethylation, and the combination of the two drugs was found to activate RAR-β expression (p16 and RAR-β are two tumor suppressor genes). On the rationale of our in vitro trials, we used low-dose decitabine and ATRA to treat 31 myeloid neoplasms deemed ineligible for intensive chemotherapy. The regimen consisted of decitabine at the dose of 15 mg/m(2) intravenously over 1 h daily for consecutive 5 days and ATRA at the dose of 20 mg/m(2) orally from day 1 to 28 except day 4 to 28 in the first cycle, and the regimen was repeated every 28 days. After 6 cycles, decitabine treatment was stopped, and ATRA treatment was continued for maintenance treatment. Treated with a median of 2 cycles (range 1-6), 7 patients (22.6 %) achieved complete remission (CR), 7 (22.6 %) marrow CR (mCR), and 4 (12.9 %) partial remission (PR). The overall remission (CR, mCR, and PR) rate was 58.1 %, and the best response (CR and mCR) rate was 45.2 %. The median overall survival (OS) was 11.0 months, the 1-year OS rate was 41.9 %, and the 2-year OS rate was 26.6 %. In univariate analyses, age, performance status, comorbidities, white blood cell counts and platelets at diagnosis, percentage of bone marrow blasts, karyotype, and treatment efficacy demonstrated no impacts on OS (P > 0.05, each). Main side effects were tolerable hematologic toxicities. In conclusion, low-dose decitabine plus ATRA is a promising treatment for patients with myeloid neoplasms judged ineligible for intensive chemotherapy. PMID:27116384

    Purpose: To model the possible interaction between cytotoxic chemotherapy and the radiation dose distribution with respect to the risk of radiation pneumonitis. Methods and Materials: A total of 18 non-small-cell lung cancer patients previously treated with helical tomotherapy at the University of Wisconsin were selected for the present modeling study. Three treatment plans were considered: the delivered tomotherapy plans; a three-dimensional conformal radiotherapy (3D-CRT) plan; and a fixed-field intensity-modulated radiotherapy (IMRT) plan. The IMRT and 3D-CRT plans were generated specifically for the present study. The plans were optimized without adjusting for the chemotherapy effect. The effect of chemotherapy was modeled as an independent cell killing process by considering a uniform chemotherapy equivalent radiation dose added to all voxels of the organ at risk. The risk of radiation pneumonitis was estimated for all plans using the Lyman and the critical volume models. Results: For radiotherapy alone, the critical volume model predicts that the two IMRT plans are associated with a lower risk of radiation pneumonitis than the 3D-CRT plan. However, when the chemotherapy equivalent radiation dose exceeds a certain threshold, the radiation pneumonitis risk after IMRT is greater than after 3D-CRT. This threshold dose is in the range estimated from clinical chemoradiotherapy data sets. Conclusions: Cytotoxic chemotherapy might affect the relative merit of competing radiotherapy plans. More work is needed to improve our understanding of the interaction between chemotherapy and the radiation dose distribution in clinical settings.

    Purpose: To assess the early clinical outcomes with concurrent cisplatin and extended-field intensity-modulated radiotherapy (EF-IMRT) for carcinoma of the cervix. Methods and Materials: Thirty-six patients with Stage IB2-IVA cervical cancer treated with EF-IMRT were evaluated. The pelvic lymph nodes were involved in 19 patients, and of these 19 patients, 10 also had para-aortic nodal disease. The treatment volume included the cervix, uterus, parametria, presacral space, upper vagina, and pelvic, common iliac, and para-aortic nodes to the superior border of L1. Patients were assessed for acute toxicities according to the National Cancer Institute Common Toxicity Criteria for Adverse Events, version 3.0. All late toxicities were scored with the Radiation Therapy Oncology Group late toxicity score. Results: All patients completed the prescribed course of EF-IMRT. All but 2 patients received brachytherapy. Median length of treatment was 53 days. The median follow-up was 18 months. Acute Grade {>=}3 gastrointestinal, genitourinary, and myelotoxicity were seen in 1, 1, and 10 patients, respectively. Thirty-four patients had complete response to treatment. Of these 34 patients, 11 developed recurrences. The first site of recurrence was in-field in 2 patients (pelvis in 1, pelvis and para-aortic in 1) and distant in 9 patients. The 2-year actuarial locoregional control, disease-free survival, overall survival, and Grade {>=}3 toxicity rates for the entire cohort were 80%, 51%, 65%, and 10%, respectively. Conclusion: Extended-field IMRT with concurrent chemotherapy was tolerated well, with acceptable acute and early late toxicities. The locoregional control rate was good, with distant metastases being the predominant mode of failure. We are continuing to accrue a larger number of patients and longer follow-up data to further extend our initial observations with this approach.

    Purpose: Supratentorial primitive neuroectodermal tumors (S-PNET) are rare and have a grim prognosis, frequently taking an aggressive course with local relapse and metastatic spread. We report the results of a mono-institutional therapeutic trial. Methods and Materials: We enrolled 15 consecutive patients to preradiation chemotherapy (CT) consisting of high-dose methotrexate, high-dose etoposide, high-dose cyclophosphamide, and high-dose carboplatin, craniospinal irradiation (CSI) with hyperfractionated accelerated radiotherapy (HART) plus focal boost, maintenance with vincristine/lomustine or consolidation with high-dose thiotepa followed by autologous stem-cell rescue. Results: Median age was 9 years; 7 were male, 8 female. Site of disease was pineal in 3, elsewhere in 12. Six patients were had no evidence of disease after surgery (NED). Of those with evidence of disease after surgery (ED), 2 had central nervous system spread. Of the 9 ED patients, 2 had complete response (CR) and 2 partial response (PR) after CT, 4 stable disease, and 1 progressive disease. Of the 7 ED patients before radiotherapy, 1 had CR, 4 PR, and 2 minor response, thus obtaining a 44% CR + PR after CT and 71% after HART. Because of rapid progression in 2 of the first 5 patients, high-dose thiotepa was systematically adopted after HART in the subsequent 10 patients. Six of 15 patients relapsed (4 locally, 1 locally with dissemination, 1 with dissemination) a mean of 6 months after starting CT, 2 developed second tumors; 5 of 6 relapsers died at a median of 13 months. Three-year progression-free survival, event-free survival, and overall survival were 54%, 34%, and 61%, respectively. Conclusion: Hyperfractionated accelerated RT was the main tool in obtaining responses in S-PNET; introducing the myeloablative phase improved the prognosis (3/10 vs. 3/5 relapses), though the outcome remained unsatisfactory despite the adoption of this intensive treatment.

    Recently, it has been reported that the relative dose intensity (RDI) of adjuvant chemotherapy (AC) influences survival in various cancers, but there are very few reports about RDI in pancreatic ductal adenocarcinoma (PDAC). The optimal timing for initiation of AC for PDAC also remains unknown. The aim of this study was to identify the significance of RDI and the time interval between surgery and initiation of AC on survival of patients with PDAC. Clinicopathological factors that affect RDI were also investigated.A total of 311 consecutive PDAC patients who underwent curative resection between May 2005 and January 2015 were enrolled. Patients who underwent neoadjuvant chemoradiation, had UICC stage IV disease, or had early recurrences within 6 months were excluded, and the remaining 168 cases were analyzed.Patients with RDIs ≥80% (n = 79) showed significantly better overall survival (OS) compared to patients with RDIs <80% (n = 55) (median survival time (MST): 45.6 months, 26.0 months, P < 0.001). Patients with no AC (n = 34) showed the worst OS (MST: 20.8 months). Whether the AC was initiated earlier or later than 8 weeks after surgery did not influence survival, either in patients with RDIs ≥80% (P = 0.79) or in those with <80% (P = 0.73). Patients in the S-1 monotherapy group (n = 49) showed significantly better OS than patients in the gemcitabine monotherapy group (n = 51) (MST: 95.0 months, 26.0 months, respectively; P = 0.001). Univariate analysis conducted after adjusting for the chemotherapeutic drug used identified several prognostic factors; male gender (P = 0.01), intraoperative blood transfusion (P = 0.005), lymph node metastasis (P = 0.03), and postoperative WBC count (P = 0.03). Multivariate analysis identified intra-plus postoperative blood transfusion (P = 0.002) and high postoperative platelet-to-lymphocyte ratios (PLR) (P = 0.04) as independent predictors of poor RDI.Efforts to

    Purpose: To determine the maximal tolerated biologic dose intensification of radiotherapy using fractional dose escalation with temozolomide (TMZ) chemotherapy in patients with newly diagnosed glioblastoma multiforme. Methods and Materials: Patients with newly diagnosed glioblastoma multiforme after biopsy or resection and with adequate performance status, bone marrow, and organ function were eligible. The patients underwent postoperative intensity-modulated radiotherapy (IMRT) with concurrent and adjuvant TMZ. All patients received a total dose of 60 Gy to the surgical cavity and residual tumor, with a 5-mm margin. IMRT biologic dose intensification was achieved by escalating from 3 Gy/fraction (Level 1) to 6 Gy/fraction (Level 4) in 1-Gy increments. Concurrent TMZ was given at 75 mg/m{sup 2}/d for 28 consecutive days. Adjuvant TMZ was given at 150-200 mg/m{sup 2}/d for 5 days every 28 days. Dose-limiting toxicity was defined as any Common Terminology Criteria for Adverse Events, version 3, Grade 3-4 nonhematologic toxicity, excluding Grade 3 fatigue, nausea, and vomiting. A standard 3+3 Phase I design was used. Results: A total of 16 patients were accrued (12 men and 4 women, median age, 69 years; range, 34-84. The median Karnofsky performance status was 80 (range, 60-90). Of the 16 patients, 3 each were treated at Levels 1 and 2, 4 at Level 3, and 6 at Level 4. All patients received IMRT and concurrent TMZ according to the protocol, except for 1 patient, who received 14 days of concurrent TMZ. The median number of adjuvant TMZ cycles was 7.5 (range, 0-12). The median survival was 16.2 months (range, 3-33). One patient experienced vision loss in the left eye 7 months after IMRT. Four patients underwent repeat surgery for suspected tumor recurrence 6-12 months after IMRT; 3 had radionecrosis. Conclusions: The maximal tolerated IMRT fraction size was not reached in our study. Our results have shown that 60 Gy IMRT delivered in 6-Gy fractions within 2 weeks with

    Background Relapsing primary central nervous system lymphoma carries a poor prognosis when treated with conventional chemotherapy with a one-year overall survival of 25-40%. Encouraging results have been shown with intensive chemotherapy followed by autologous hematopoietic stem cell rescue. We report the results of a large multicenter retrospective analysis of intensive chemotherapy followed by hematopoietic stem cell rescue in immunocompetent adult patients with primary central nervous system lymphoma or intraocular lymphoma after the failure of high-dose methotrexate-based treatment. Design and Methods Patients were included if they received intensive chemotherapy with a combination of thiotepa, busulfan and cyclophosphamide. Seventy-nine patients (median age 52.4 years, range 23-67 years) were identified. All of the patients except 5 received a salvage treatment after the failure of high-dose methotrexate. After salvage treatment and just before intensive chemotherapy followed by hematopoietic stem cell rescue, 32 patients were in complete response, 26 patients were in partial response, 2 patients had stable disease and 19 patients had progressive disease. Results With a median follow up of 56 months, the 5-year overall survival probability was 51% in the whole population and 62% among patients who were chemosensitive to the salvage treatment. The 5-year event-free survival probability was 37.8% in the whole population and 43.7% in the chemosensitive subpopulation. Neurocognitive assessments in a subset of patients suggest no evidence of intensive chemotherapy-induced neurocognitive decline. Conclusions Thiotepa, busulfan and cyclophosphamide-based intensive chemotherapy is an effective treatment for refractory and recurrent primary central nervous system lymphoma in chemosensitive patients up to 65 years of age. The role of intensive chemotherapy followed by hematopoietic stem cell rescue in chemorefractory patients needs to be more accurately defined. PMID

    This study was designed to assess the results of protracted courses of ESHAP (etoposide, cytarabine, cisplatin, methylprednisolone) therapy followed by intensive chemotherapy and hematopoietic cell transplantation (IC+HCT) for relapsed or refractory non-Hodgkin's lymphoma (NHL). Treatment consisted of 3 cycles of ESHAP; responsive patients (pts) then received 3 more cycles, and IC+HCT was used for pts in maintained partial (PR) or complete (CR) remission after the sixth ESHAP. Sixty-five pts entered the study. At enrollment, 27 pts had bone marrow (BM) and/or central nervous system (CNS) lymphomatous infiltration. Disease status was primary refractory lymphoma in 41 pts (63 %), and relapse in 24 pts (37 %). Results showed that two pts were not evaluable for the therapeutic response because of early treatment-related death. Thirty-nine (62 %) pts entered PR or CR after 3 cycles of ESHAP. Eleven pts subsequently had disease progression. Twenty-eight pts were in persistent CR or PR after 6 cycles of ESHAP. Refractory pts did not show a different response rate to relapsing pts (chi2= 1.73). Five pts were excluded from IC+HCT because of an inadequate graft or treatment-related toxicity. Twenty-three (35 %) pts completed the procedure. Five pts (22 %) relapsed after IC+HCT. The overall survival rate of the 39 responsive pts is 45 % at 60 months, with a median survival time of 30 months. Median survival among the 35 pts in whom second-line chemotherapy failed is 7.1 months, with a 4-year survival rate of 3 %. Despite the poor prognostic features of this group, 45% of pts responding to the first 3 cycles of chemotherapy are in prolonged remission, suggesting that rather than to transplant after just 2 cycles of salvage therapy, pursuing second-line chemotherapy may better discriminate between patients more likely to benefit from a subsequent transplant.

    Purpose: The value of intensity-modulated radiation therapy (IMRT) after doxorubicin-based chemotherapy in primary mediastinal large B-cell lymphoma (PMBCL) is unknown. We assessed the dosimetric parameters, treatment outcomes, and toxicity of IMRT in PMBCL. Methods and Materials: Forty-one PMBCL patients underwent mediastinal IMRT after doxorubicin-based chemotherapy. Thirty-eight patients had stage I-II disease, and 3 patients had stage III-IV disease. Most patients presented with bulky mediastinal disease (65.9%) and local invasion (82.9%). The dose-volume histograms of the target volume and critical normal structures were evaluated. Results: The average planning target volume (PTV) mean dose was 39 Gy. Only 0.5% and 1.4% of the PTV received <90% and <95% of the prescribed dose, respectively, indicating excellent target coverage. The median mean lung dose and percentage lung volume receiving 20 Gy (V20) were 16.3 Gy and 30.6%. The 5-year overall survival (OS) and local control (LC) were 95.1% and 89.8%. After chemotherapy, consolidation radiation therapy in patients with complete/partial response resulted in significantly better survival than salvage radiation therapy in patients with stable/progressive disease (3-year OS 100% vs 75%; 3-year LC 96.6% vs 62.5%). No grade 4 or 5 acute or late toxicities occurred. Conclusions: Mediastinal IMRT after doxorubicin-based chemotherapy can be safely and efficiently delivered, and it provides favorable outcomes in PMBCL patients with a large target volume and high-risk features.

    Purpose: To evaluate the feasibility and efficacy of moderately accelerated intensity-modulated radiation therapy (IMRT) along with weekly cisplatin, after induction chemotherapy, in patients with locally advanced unresectable head and neck cancer (HNC). Methods and Materials: Patients with Stage III or IV locally advanced HNC, without progressive disease after three courses of induction chemotherapy, received concurrent chemo-IMRT (weekly cisplatin 30 mg/m{sup 2} plus simultaneous integrated boost IMRT). A total of 67.5 Gy in 30 fractions were delivered to primary tumor and involved nodes, 60 Gy in 30 fractions to high-risk nodal areas, and 55.5 Gy in 30 fractions to low-risk nodal areas. Results: In all, 36 patients (median age, 56 years) with International Union Against Cancer (UICC) Stage III (n = 5) and IV (n = 31) were included. Of the 36 patients, 17 had received CF (cisplatin and 5-fluorouracil (CF) and 19 had received docetaxel cisplatin and 5-fluorouracil (DCF). During concurrent chemoradiation, 11 of 36 patients (30.5%) experienced Grade III mucositis (CF, 47%; DCF, 15%; p < 0.04). Grade III pharyngeal-esophageal toxicity was observed in 5 of 19 patients (26.3%; CF, 0.0%; DCF, 26.3%; p = 0.02). Two patients died of complications (5.5%). After chemoradiation, the complete response rate was 63.8%. Two-year local control was 88.7%. Two-year progression free survival and overall survival were 74.5% and 60.9%, respectively. Conclusions: In our experience, a moderately accelerated chemo-IMRT was feasible after induction chemotherapy. However, a noteworthy early death rate of 5.5% was observed. Intensive supportive care strategies should be defined to better manage radiation-induced toxic effects. Longer follow-up is required to determine the incidence of late radiation toxicities and tumor control rates.

    Abstract Mediastinal nonseminomatous germ cell tumor (MNSGCT)-associated histiocytic proliferations are rare and rapidly fatal disorders. Standard treatment modalities have yet to be established. We report a case of MNSGCT-associated hemophagocytic syndrome that evolved into malignant histiocytosis/disseminated histiocytic sarcoma (MH/HS), which was initially treated with intravenous immunoglobulin, corticosteroids, and cyclosporine. Then, thalidomide plus cyclophosphamide, adriamycin, oncovin, prednisolone chemotherapy followed by alemtuzumab-containing reduced-intensity allogeneic peripheral blood stem cell transplantation (PBSCT) was used as salvage therapy. The severe constitutional symptoms and pancytopenia resolved shortly after thalidomide with cyclophosphamide, adriamycin, oncovin, prednisolone. After PBSCT, the patient developed steroid-dependent skin graft-versus-host disease, but maintained a functional life for 1.5 years. Rapid resolution of chronic graft-versus-host disease preceded the fulminant recurrence of hemophagocytic syndrome and MH/HS. Thalidomide plus chemotherapy followed by alemtuzumab-containing reduced intensity allogeneic PBSCT is effective in allaying MNSGCT-associated histiocytic disorders, but does not prevent eventual relapse. However, further posttransplant immune modulation should be developed to completely eradicate the residual MH/HS cells. PMID:26765473

    Background The randomized controlled Pediatric Oncology Group study 9233 tested the hypothesis that dose-intensive (DI) chemotherapy would improve event-free survival (EFS) for children <3 years of age with newly diagnosed malignant brain tumors. Methods Of 328 enrolled eligible patients, diagnoses were medulloblastoma (n = 112), ependymoma (n = 82), supratentorial primitive neuroectodermal tumor (sPNET, n = 38) and other malignant brain tumors (n = 96), and were randomized to 72 weeks of standard dose chemotherapy (Regimen A, n = 162) or DI chemotherapy (Regimen B, n = 166). Radiation therapy (RT) was recommended for patients with evidence of disease at completion of chemotherapy or who relapsed within 6 months of chemotherapy completion. Results Distributions of EFS for Regimens A and B were not significantly different (P = 0.32) with 2- and 10-year rates of 22.8% ± 3.3% and 15.4% ± 3.7%, and 27.1% ± 3.4% and 20.8% ± 3.8%, respectively. Thus, the study hypothesis was rejected. While distributions of EFS and OS were not significantly different between Regimens A and B for patients with medulloblastoma and sPNET, DI chemotherapy resulted in significantly improved EFS distribution (P = .0011) (2-year EFS rates of 42.1% vs. 19.6% with SD chemotherapy), but not OS distribution, for patients with centrally confirmed ependymoma. The degree of surgical resection affected EFS, OS or both for most tumor groups. Approximately 20%, 40% and 20% of patients with medulloblastoma, ependymoma treated with DI chemotherapy, and sPNET, respectively appear to have been cured without RT. Of 11 toxic deaths on study, 10 occurred on the DI chemotherapy arm. Conclusions Prolonged dose-intensive chemotherapy given to infants with malignant brain tumors resulted in increased EFS only for patients with ependymoma. PMID:24335695

    Purpose: To retrospectively review our experience with whole abdominopelvic radiotherapy (WAPRT) using intensity-modulated arc therapy in the palliative treatment of chemotherapy-resistant ovarian cancer with bulky peritoneal disease. Methods and Materials: Between April 2002 and April 2008, 13 patients were treated with WAPRT using intensity-modulated arc therapy. We prescribed a dose of 33 Gy to be delivered in 22 fractions of 1.5 Gy to the abdomen and pelvis. All patients had International Federation of Gynecology and Obstetrics Stage III or IV ovarian cancer at the initial diagnosis. At referral, the median age was 61 years, and the patients had been heavily pretreated with surgery and chemotherapy. All patients had symptoms from their disease, including gastrointestinal obstruction or subobstruction in 6, minor gastrointestinal symptoms in 2, pain in 4, ascites in 1, and vaginal bleeding in 2. A complete symptom or biochemical response required complete resolution of the patient's symptoms or cancer antigen-125 level. A partial response required {>=}50% resolution of these parameters. The actuarial survival was calculated from the start of radiotherapy. Results: The median overall survival was 21 weeks, with a 6-month overall survival rate of 45%. The 9 patients who completed treatment obtained a complete symptom response, except for ascites (partial response). The median and mean response duration (all symptoms grouped) was 24 and 37 weeks, respectively. Of the 6 patients presenting with obstruction or subobstruction, 4 obtained a complete symptom response (median duration, 16 weeks). Conclusion: WAPRT delivered using intensity-modulated arc therapy offers important palliation in the case of peritoneal metastatic ovarian cancer. WAPRT resolved intestinal obstruction for a substantial period.

    Purpose: To determine how chemotherapy agents affect radiation dose parameters that correlate with acute hematologic toxicity (HT) in patients treated with pelvic intensity modulated radiation therapy (P-IMRT) and concurrent chemotherapy. Methods and Materials: We assessed HT in 141 patients who received P-IMRT for anal, gynecologic, rectal, or prostate cancers, 95 of whom received concurrent chemotherapy. Patients were separated into 4 groups: mitomycin (MMC) + 5-fluorouracil (5FU, 37 of 141), platinum ± 5FU (Cis, 32 of 141), 5FU (26 of 141), and P-IMRT alone (46 of 141). The pelvic bone was contoured as a surrogate for pelvic bone marrow (PBM) and divided into subsites: ilium, lower pelvis, and lumbosacral spine (LSS). The volumes of each region receiving 5-40 Gy were calculated. The endpoint for HT was grade ≥3 (HT3+) leukopenia, neutropenia or thrombocytopenia. Normal tissue complication probability was calculated using the Lyman-Kutcher-Burman model. Logistic regression was used to analyze association between HT3+ and dosimetric parameters. Results: Twenty-six patients experienced HT3+: 10 of 37 (27%) MMC, 14 of 32 (44%) Cis, 2 of 26 (8%) 5FU, and 0 of 46 P-IMRT. PBM dosimetric parameters were correlated with HT3+ in the MMC group but not in the Cis group. LSS dosimetric parameters were well correlated with HT3+ in both the MMC and Cis groups. Constrained optimization (0chemotherapy received. Patients receiving P-IMRT ± 5FU have better bone marrow tolerance than those receiving irradiation concurrent with either Cis or MMC.

    The increasing number of unfit patients calls for better risk assessment prior to initiating anti-tumor treatment. This is a major concern in the prevention and reduction of treatment-related complications. The aim of our study was to evaluate the nutritional status for the risk assessment of patients qualifying to receive the gemcitabine and oxaliplatin (GEMOX) regimen. This single-center, retrospective study examined baseline clinical and biological characteristics in a cohort of 165 unselected, consecutive cancer patients receiving GEMOX. Malnutrition was defined as either body mass index (BMI) <18.5 kg/m(2), body weight loss >10% over 3 mo, or albuminemia <35 g/L. A total of 165 patients (median age 61 yr, PS 0-1: 71%) were studied. Malnutrition was seen in 43% of PS 0-1 patients, vs. 60% of PS 2 and 66% of PS 3 patients (P > 0.05). Median relative dose-intensity was 0.90 (0.17-1.04). GEMOX dose-intensity correlated negatively with loss of baseline weight (r = -0.24, P < 0.02). In patients who did not complete more than 2 cycles of chemotherapy, median PS (P < 0.01), mean C-reactive protein (CRP; P < 0.01), and mean albuminemia (P < 0.05) were, respectively, significantly higher, higher, and lower. Malnutrition is associated with a high risk of early discontinuance of treatment. Systematic basal evaluation of the nutritional status, including albuminemia and BMI, is recommended. PMID:24099412

    We evaluate the long-term results of a prospective clinical study enrolling more than 100 adult patients with Burkitt lymphoma/leukemia. Depending on extent of disease, treatment consisted of six to eight rituximab infusions and four to six courses of intensive chemotherapy (attenuated in patients aged >55 years) with high-dose methotrexate, fractionated ifosfamide/cyclophosphamide, other drugs in rotation, and intrathecal chemoprophylaxis. One-hundred five patients were treated (median age 47 years, range 17–78 years); 48% had Burkitt leukemia, 25% were older than 60 years, 37% had an Eastern Cooperative Oncology Group performance score >1, and 14% were positive for human immunodeficiency virus. The complete response rate and 3-year overall and disease-free survival rates were 79%, 67% and 75%, respectively, ranging from 100% to 45% for survival (P=0.000) and from 100% to 60% for disease-free survival (P=0.01) in patients with low, intermediate and high adapted International Prognostic Index scores. In multivariate analysis, only age (≤ versus >60 years) and performance status (0–1 versus >1) retained prognostic significance, identifying three risk groups with overall and disease-free survival probabilities of 88% and 87.5%, 57% and 70.5%, 20% and 28.5% (P=0.0000 and P=0.0001), respectively. The relapse rate was only 7% in patients treated with an intercycle interval ≤25 days. This regimen achieved 100% curability in patients with low adapted International Prognostic Index scores (21% of total), and very close to 90% in patients aged ≤60 years with performance score 0–1 (48% of total). Rapid diagnosis of Burkitt lymphoma/leukemia with prompt referral of patients to prevent clinical deterioration, and careful supervision of treatment without chemotherapy delay can achieve outstanding therapeutic results.

    The prognostic value of the tumour response to induction chemotherapy (IC) for long-term survival outcomes after intensity-modulated radiation therapy in nasopharyngeal carcinoma (NPC) remains unknown. We retrospectively reviewed 1811 consecutive patients with newly diagnosed NPC treated using IMRT, and 399 eligible patients with pre- and post-induction chemotherapy magnetic resonance images were recruited. The clinicopathological features of patients with different tumour responses were compared using the Chi-square test or Fisher’s exact test. Prognostic value was assessed using a multivariate Cox proportional hazards model. After IC, 101/399 (25.3%) patients had a complete tumour response overall (CR), 262 (65.7%) had a partial response (PR) and 36 (9.0%) had stable disease (SD). The 4-year disease-free survival (DFS), overall survival (OS), distant metastasis-free survival (DMFS) and locoregional relapse-free survival (LRRFS) rates for CR vs. PR vs. SD were 90.0% vs. 79.0% vs. 58.2% (CR vs. PR: P1 = 0.007; CR vs. SD: P2 < 0.001; PR vs. SD: P3 = 0.004), 95.7% vs. 88.7% vs. 70.2% (P1 = 0.017, P2 < 0.001, P3 = 0.005), 92.0% vs. 87.4% vs. 74.3% (P1 = 0.162, P2 = 0.005, P3 = 0.029) and 95.9% vs. 88.8% vs. 81.8% (P1 = 0.024, P2 = 0.006, P3 = 0.268), respectively. Multivariate analysis identified that the tumour response to IC was an independent prognostic factor for DFS, OS and LRRFS. PMID:27099096

    Purpose: To investigate the rate of high-grade treatment-related pneumonitis (TRP) in patients with advanced non-small-cell lung cancer (NSCLC) treated with concurrent chemotherapy and intensity-modulated radiotherapy (IMRT). Methods and Materials: From August 2002 to August 2005, 151 NSCLC patients were treated with IMRT. We excluded patients who did not receive concurrent chemotherapy or who had early-stage cancers, a history of major lung surgery, prior chest RT, a dose <50 Gy, or IMRT combined with three-dimensional conformal RT (3D-CRT). Toxicities were graded by Common Terminology Criteria for Adverse Events version 3.0. Grade {>=}3 TRP for 68 eligible IMRT patients was compared with TRP among 222 similar patients treated with 3D-CRT. Results: The median follow-up durations for the IMRT and 3D-CRT patients were 8 months (range, 0-27 months) and 9 months (range, 0-56 months), respectively. The median IMRT and 3D-CRT doses were 63 Gy. The median gross tumor volume was 194 mL (range, 21-911 mL) for IMRT, compared with 142 mL (range, 1.5-1,186 mL) for 3D-CRT (p = 0.002). Despite the IMRT group's larger gross tumor volume, the rate of Grade {>=}3 TRP at 12 months was 8% (95% confidence interval 4%-19%), compared with 32% (95% confidence interval 26%-40%) for 3D-CRT (p = 0.002). Conclusions: In advanced NSCLC patients treated with chemoradiation, IMRT resulted in significantly lower levels of Grade {>=}3 TRP compared with 3D-CRT. Clinical, dosimetric, and patient selection factors that may have influenced rates of TRP require continuing investigation. A randomized trial comparing IMRT with 3D-CRT has been initiated.

    Intensive chemotherapy followed by allogeneic stem cell transplantation (alloSCT) can cure AML. Most studies on alloSCT in elderly AML report results of highly selected patient cohorts. Hardly any data exist on the effectiveness of prospective strategies intended to bring as many patients as possible to transplant. Between 2006 and 2011 we implemented a treatment algorithm for all newly diagnosed AML patients aged 61-75 years, consisting of intensive chemotherapy cycles to induce complete remission, followed by alloSCT. 44 of 60 (73%) newly diagnosed elderly AML patients started with chemotherapy. By meticulously following our algorithm in almost all patients, we could induce complete remission (CR) in 66% of patients starting with chemotherapy, and transplant 32% of these patients in continuous CR. Main reasons for failure were early relapse (16%), early death (14%), primary refractory disease (9%), and patient or physician decision to stop treatment (16%). Patients in continuous CR after first induction benefit most with 36% long-term survival. Patients not in CR after first induction benefit less; although additional chemotherapy induces CR in 45% of these patients, only 23% are transplanted and no long-term survival is observed, mainly due to relapse. Long-term survival in the group of 44 patients is 9% (median 4.5 years after alloSCT). Considering that 27% of patients do not start with chemotherapy and 64% of patients starting with chemotherapy do not reach alloSCT, the reasons for failure presented here should be used as a guide to develop new treatment algorithms to improve long-term survival in elderly AML patients.

    Purpose: To test the hypothesis that intensity modulated radiation therapy (IMRT) can reduce radiation dose to functional bone marrow (BM) in patients with pelvic malignancies (phase IA) and estimate the clinical feasibility and acute toxicity associated with this technique (phase IB). Methods and Materials: We enrolled 31 subjects (19 with gynecologic cancer and 12 with anal cancer) in an institutional review board-approved prospective trial (6 in the pilot study, 10 in phase IA, and 15 in phase IB). The mean age was 52 years; 8 of 31 patients (26%) were men. Twenty-one subjects completed {sup 18}F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) simulation and magnetic resonance imaging by use of quantitative IDEAL (IDEAL IQ; GE Healthcare, Waukesha, WI). The PET/CT and IDEAL IQ were registered, and BM subvolumes were segmented above the mean standardized uptake value and below the mean fat fraction within the pelvis and lumbar spine; their intersection was designated as functional BM for IMRT planning. Functional BM-sparing vs total BM-sparing IMRT plans were compared in 12 subjects; 10 were treated with functional BM-sparing pelvic IMRT per protocol. Results: In gynecologic cancer patients, the mean functional BM V{sub 10} (volume receiving {>=}10 Gy) and V{sub 20} (volume receiving {>=}20 Gy) were 85% vs 94% (P<.0001) and 70% vs 82% (P<.0001), respectively, for functional BM-sparing IMRT vs total BM-sparing IMRT. In anal cancer patients, the corresponding values were 75% vs 77% (P=.06) and 62% vs 67% (P=.002), respectively. Of 10 subjects treated with functional BM-sparing pelvic IMRT, 3 (30%) had acute grade 3 hematologic toxicity or greater. Conclusions: IMRT can reduce dose to BM subregions identified by {sup 18}F-fluorodeoxyglucose-PET/CT and IDEAL IQ. The efficacy of BM-sparing IMRT is being tested in a phase II trial.

    Purpose: To conduct a retrospective review of 168 consecutively treated locally advanced head-and-neck cancer (LAHNC) patients treated with intensity-modulated radiotherapy (IMRT)/chemotherapy, to determine the rate and risk factors for developing hypothyroidism. Methods and Materials: Intensity-modulated radiotherapy was delivered in 33 daily fractions to 69.3 Gy to gross disease and 56.1 Gy to clinically normal cervical nodes. Dose-volume histograms (DVHs) of IMRT plans were used to determine radiation dose to thyroid and were compared with DVHs using conventional three-dimensional radiotherapy (3D-RT) in 10 of these same patients randomly selected for replanning and with DVHs of 16 patients in whom the thyroid was intentionally avoided during IMRT. Weekly paclitaxel (30 mg/m{sup 2}) and carboplatin area under the curve-1 were given concurrently with IMRT. Results: Sixty-one of 128 evaluable patients (47.7%) developed hypothyroidism after a median of 1.08 years after IMRT (range, 2.4 months to 3.9 years). Age and volume of irradiated thyroid were associated with hypothyroidism development after IMRT. Compared with 3D-RT, IMRT with no thyroid dose constraints resulted in significantly higher minimum, maximum, and median dose (p < 0.0001) and percentage thyroid volume receiving 10, 20, and 60 Gy (p < 0.05). Compared with 3D-RT, IMRT with thyroid dose constraints resulted in lower median dose and percentage thyroid volume receiving 30, 40, and 50 Gy (p < 0.005) but higher minimum and maximum dose (p < 0.005). Conclusions: If not protected, IMRT for LAHNC can result in higher radiation to the thyroid than with conventional 3D-RT. Techniques to reduce dose and volume of radiation to thyroid tissue with IMRT are achievable and recommended.

    Myeloablative conditioning regimens for hematopoietic stem cell transplant (HSCT) are known to affect endocrine function, but little is known regarding reduced intensity conditioning (RIC) regimens. We retrospectively reviewed 114 children and young adults after single RIC HSCT. The analysis was grouped by age (<2 and ⩾2 years) and diagnosis (hemophagocytic lymphohistiocystosis/X-linked lymphoproliferative syndrome (HLH/XLP), other immune disorders, metabolic/genetic disorders). All groups displayed short stature by mean height-adjusted Z-score (HAZ) before (-1.29) and after HSCT (HAZ -1.38, P=0.47). After HSCT, younger children with HLH/XLP grew better (HAZ -3.41 vs -1.65, P=0.006), whereas older subjects had decline in growth (HAZ -0.8 vs -1.01, P=0.06). Those with steroid therapy beyond standard GVHD prophylaxis were shorter than those without (P 0.04). After HSCT, older subjects with HLH/XLP became thinner with a mean body mass index (BMI) Z-score of 1.20 vs 0.64, P=0.02, and similar to metabolic/genetic disorders (BMI-Z= 0.59 vs -0.99, P<0.001). BMI increased among younger children in these same groups. Thyroid function was abnormal in 24% (18/76). 25-OH vitamin D levels were insufficient in 73% (49/65), with low bone mineral density in 8 of 19 evaluable subjects. Despite RIC, children and young adults still have significant late endocrine effects. Further research is required to compare post-transplant endocrine effects after RIC to those after standard chemotherapy protocols. PMID:26974276

    The introduction of Rituximab has improved the outcome and survival rates of Burkitt lymphoma (BL). However, early relapse and refractoriness are current limitations of BL treatment and new biological factors affecting the outcome of these patients have not been explored. This study aimed to identify the presence of genomic changes that could predict the response to new therapies in BL. Forty adolescent and adult BL patients treated with the Dose-Intensive Chemotherapy Including Rituximab (Burkimab) protocol (Spanish Programme for the Study and Treatment of Haematological Malignancies; PETHEMA) were analysed using array-based comparative genomic hybridization (CGH). In addition, the presence of TP53, TCF3 (E2A), ID3 and GNA13 mutations was assessed by next-generation sequencing (NGS). Ninety-seven per cent of the patients harboured genomic imbalances. Losses on 11q, 13q, 15q or 17p were associated with a poor response to Burkimab therapy (P = 0·038), shorter progression-free survival (PFS; P = 0·007) and overall survival (OS; P = 0·009). The integrative analysis of array-CGH and NGS showed that 26·3% (5/19) and 36·8% (7/19) of patients carried alterations in the TP53 and TCF3 genes, respectively. TP53 alterations were associated with shorter PFS (P = 0·011) while TCF3 alterations were associated with shorter OS (P = 0·032). Genetic studies could be used for risk stratification of BL patients treated with the Burkimab protocol. PMID:26567765

    Purpose: To test the hypothesis that the volume of pelvic bone marrow (PBM) receiving 10 and 20 Gy or more (PBM-V{sub 10} and PBM-V{sub 20}) is associated with acute hematologic toxicity (HT) in anal cancer patients treated with concurrent chemoradiotherapy. Methods and Materials: We analyzed 48 consecutive anal cancer patients treated with concurrent chemotherapy and intensity-modulated radiation therapy. The median radiation dose to gross tumor and regional lymph nodes was 50.4 and 45 Gy, respectively. Pelvic bone marrow was defined as the region extending from the iliac crests to the ischial tuberosities, including the os coxae, lumbosacral spine, and proximal femora. Endpoints included the white blood cell count (WBC), absolute neutrophil count (ANC), hemoglobin, and platelet count nadirs. Regression models with multiple independent predictors were used to test associations between dosimetric parameters and HT. Results: Twenty patients (42%) had Stage T3-4 disease; 15 patients (31%) were node positive. Overall, 27 (56%), 24 (50%), 4 (8%), and 13 (27%) experienced acute Grade 3-4 leukopenia, neutropenia, anemia, and thrombocytopenia, respectively. On multiple regression analysis, increased PBM-V{sub 5}, V{sub 10}, V{sub 15}, and V{sub 20} were significantly associated with decreased WBC and ANC nadirs, as were female gender, decreased body mass index, and increased lumbosacral bone marrow V{sub 10}, V{sub 15}, and V{sub 20} (p < 0.05 for each association). Lymph node positivity was significantly associated with a decreased WBC nadir on multiple regression analysis (p < 0.05). Conclusion: This analysis supports the hypothesis that increased low-dose radiation to PBM is associated with acute HT during chemoradiotherapy for anal cancer. Techniques to limit bone marrow irradiation may reduce HT in anal cancer patients.

    Purpose: To evaluate the dosimetric and clinical outcomes of involved-field intensity-modulated radiotherapy (IF-IMRT) for patients with early-stage Hodgkin's lymphoma (HL) with mediastinal involvement. Methods and Materials: Fifty-two patients with early-stage HL that involved the mediastinum were reviewed. Eight patients had Stage I disease, and 44 patients had Stage II disease. Twenty-three patients (44%) presented with a bulky mediastinum, whereas 42 patients (81%) had involvement of both the mediastinum and either cervical or axillary nodes. All patients received combination chemotherapy followed by IF-IMRT. The prescribed radiation dose was 30-40 Gy. The dose-volume histograms of the target volume and critical normal structures were evaluated. Results: The median mean dose to the primary involved regions (planning target volume, PTV1) and boost area (PTV2) was 37.5 Gy and 42.1 Gy, respectively. Only 0.4% and 1.3% of the PTV1 and 0.1% and 0.5% of the PTV2 received less than 90% and 95% of the prescribed dose, indicating excellent PTV coverage. The median mean lung dose and V20 to the lungs were 13.8 Gy and 25.9%, respectively. The 3-year overall survival, local control, and progression-free survival rates were 100%, 97.9%, and 96%, respectively. No Grade 4 or 5 acute or late toxicities were reported. Conclusions: Despite the large target volume, IF-IMRT gave excellent dose coverage and a favorable prognosis, with mild toxicity in patients with early-stage mediastinal HL.

    An increasing number of older patients are suffering from aggressive lymphoma. Effective and more tolerable treatment regimens are urgently needed for this growing patient population. Patients with aggressive lymphoma not eligible for anthracycline-based first-line therapy or intensive salvage regimens were treated with the rituximab-bendamustine-lenalidomide (R-BL) regimen (rituximab 375 mg/m(2)  day 1, bendamustine 70 mg/m(2)  d 1, 2, lenalidomide 10 mg d 1-21) for six cycles every 4 weeks. Forty-one patients with a median age of 75 (range 40-94) years were enrolled: 33 patients had substantial co-morbidities. 13 patients were not eligible for anthracycline-based first-line chemotherapy, 28 patients had relapsed/refractory disease. The primary endpoint, overall response, was achieved by 25 (61%) patients (95% confidence interval 45-76%). Grade ≥ 3 toxicity comprised haematological (59%), skin (15%), constitutional (15%) and neurological (12%) events. 9 patients died during trial treatment: 5 from lymphoma progression, 2 from toxicity, 2 with sudden death. After a median follow-up of 25·9 (interquartile range 20·4-31·6) months, 13 patients were still alive. Median overall survival was 14·5 months. In conclusion, R-BL can be considered a treatment option for elderly patients with treatment naïve or relapsed/refractory aggressive lymphoma not eligible for standard aggressive regimens.

    Pegfilgrastim (Neulasta) has proven efficacy as supportive therapy in a variety of 21-day chemotherapy regimens, but has not been studied in dose intensive, rapidly cycling regimens utilising cell-cycle active drugs (e.g. anti-metabolites) such as hyper-CVAD. This study examined whether pegfilgrastim was safe and lead to similar kinetics of neutrophil recovery as daily granulocyte colony stimulating factor (G-CSF). Using retrospective analysis, patients receiving pegfilgrastim (6 mg) were matched with controls (G-CSF 5 microg kg-1 per day) for a cycle of chemotherapy, prior chemotherapy, dose of cytarabine received, age (<60 or >60 years), diagnosis and bone marrow involvement. The primary endpoint was duration of grade IV neutropenia (absolute neutrophil count, ANC < 500 microl-1). Secondary endpoints included time to neutrophil recovery, incidence of febrile neutropenia, positive blood cultures and delay in subsequent chemotherapy. This study identified 124 pegfilgrastim supported cycles in 43 patients and successfully matched them to 124 G-CSF supported cycles from 38 patients treated between January 1999 and July 2005. There were no significant differences between pegfilgrastim and G-CSF groups in baseline or treatment-related variables. The median duration of grade IV neutropenia was 4 days in both groups (P = 0.55). Time to neutrophil recovery, incidence of febrile neutropenia, positive blood cultures and delay in subsequent chemotherapy were similar in both groups. Once per cycle dosing of pegfilgrastim appears safe and as effective as daily G-CSF for supporting the hyper-CVAD chemotherapy regimen. PMID:17064993

    This paper evaluates a recent study whereby a four-drug combination regimen adding bevacizumab to triplet fluorouracil, oxaliplatin and irinotecan chemotherapy is described for the first-line treatment of metastatic colorectal cancer. It extends the use of intensive medical treatments combining chemotherapy and the VEGF inhibitor bevacizumab, opening new perspectives for the design of four-drug intensive regimen-associating chemotherapy and targeted agents. In the future, these four-drug intensive regimens should be further improved for efficacy:toxicity ratio and verification in randomized trials. PMID:21545334

    The objective was to determine the role of dose intensive induction chemotherapy in patients with soft tissue sarcomas (STS) that were considered unresectable. Treatment consisted of 2-3 cycles of doxorubicin (Dox) and ifosfamide (Ifo) followed by high dose chemotherapy with ifosfamide, carboplatin, etoposide (HD-ICE) plus peripheral blood stem cell transplantation (PBSCT). 30 out of 631 consecutive patients, median age 46 years (21-62), with high grade STS were included. 29 patients completed at least 2 cycles of Dox/Ifo. HD-ICE was withheld because of progressive disease (PD) in 5 patients, neurotoxicity in 6 cases, insufficient peripheral blood stem cell (PBSC) mobilization, complete remission (CR) and refusal in 1 patient each. HD-ICE was associated with non-haematological grade III toxicity including emesis, mucositis, fever, neurotoxicity, and transaminase level elevation. Two additional patients attained a partial response after HD-ICE. Overall, 24 of 30 (80%) patients underwent surgery, with complete tumor resections in 19 patients (63% of all patients, 79% of the operated subgroup); however, 2 of these required amputation. After a median follow up period of 50 months in surviving patients (range, 26-120), 5-year PFS and OS rates were 39% and 48%, respectively. Induction chemotherapy plus consolidation HD-ICE is generally feasible, but is associated with significant neurotoxicity. The advantage of HD-ICE over conventional dose chemotherapy plus external beam radiation therapy (EBRT) in non-resectable disease remains unproven. PMID:24091981

    Background and purpose To retrospectively evaluate locoregional control (LRC), survival and toxicity in anal cancer patients treated with simultaneous integrated boost - intensity modulated radiation therapy (SIB-IMRT) ± concurrent chemotherapy. Methods and materials Patients with squamous cell anal carcinoma stage T1(≥1 cm)-4, N0-3, M0-1 were included. All patients were treated with SIB-IMRT to a total dose of 59.4 Gy delivered to the primary tumor and macroscopically involved lymph nodes and 49.5 Gy to elective lymph node areas. If macroscopic residual tumor was still present in the fifth week of irradiation, a sequential boost of 5.4 Gy was given. Concurrent chemotherapy was administered in locally advanced cases. Acute and late toxicity were scored. Results One hundred and six patients treated consecutively between April 2006 and December 2012 were included. Eighty-seven (82.1%) patients received concurrent chemotherapy. The median follow-up was 47 months (range 2-104 months). Ninety-eight patients reached a clinical complete response (92.5%). Four-year actuarial LRC rate, overall survival and colostomy-free survival were 79%, 77% and 77%, respectively. Acute grade ≥3 toxicity occurred in 67.9% of the patients. Late grade 3 toxicity was seen in 16 patients (15.1%). Conclusions SIB-IMRT ± concurrent chemotherapy for anal cancer was effective with acceptable toxicity. PMID:26878244

  16. Anticancer chemotherapy

    Weller, R.E.

    1988-10-01

    Despite troubled beginnings, anticancer chemotherapy has made significant contribution to the control of cancer in man, particularly within the last two decades. Early conceptual observations awakened the scientific community to the potentials of cancer chemotherapy. There are now more than 50 agents that are active in causing regression of clinical cancer. Chemotherapy's major conceptual contributions are two-fold. First, there is now proof that patients with overt metastatic disease can be cured, and second, to provide a strategy for control of occult metastases. In man, chemotherapy has resulted in normal life expectancy for some patients who have several types of metastatic cancers, including choriocarcinoma, Burkitt's lymphomas, Wilm's tumor, acute lymphocytic leukemia, Hodgkins disease, diffuse histiocytic lymphoma and others. Anticancer chemotherapy in Veterinary medicine has evolved from the use of single agents, which produce only limited remissions, to the concept of combination chemotherapy. Three basic principles underline the design of combination chemotherapy protocols; the fraction of tumor cell killed by one drug is independent of the fraction killed by another drug; drugs with different mechanisms of action should be chosen so that the antitumor effects will be additive; and since different classes of drugs have different toxicities the toxic effects will not be additive.

    Acute myeloid leukemia with high white blood cell count (WBC) is a medical emergency. A reduction of tumor burden with hydroxyurea may prevent life-threatening complications induced by straight chemotherapy. To evaluate this strategy, we reviewed medical charts of adult patients admitted to our institution from 1997 to 2011 with non-promyelocytic AML and WBC over 50 G/L. One hundred and sixty patients were included with a median WBC of 120 G/L (range 50-450), 107 patients received hydroxyurea prior to chemotherapy, and 53 received emergency induction chemotherapy (CT). Hospital mortality was lower for patients treated with hydroxyurea (34% versus 19%, p = 0.047) even after adjusting for age (p < 0.01) and initial WBC count (p = 0.02). No evidence of any difference between treatment groups in terms of WBC decline kinetics and disease free survival (p = 0.87) was found. Oral hydroxyurea prior to chemotherapy seems a safe and efficient strategy to reduce early death of hyperleukocytic AML patients. PMID:26849624

    Purpose Children's Oncology Group study AALL00P2 was designed to assess the feasibility and safety of adding nelarabine to a BFM 86–based chemotherapy regimen in children with newly diagnosed T-cell acute lymphoblastic leukemia (T-ALL). Patients and Methods In stage one of the study, eight patients with a slow early response (SER) by prednisone poor response (PPR; ≥ 1,000 peripheral blood blasts on day 8 of prednisone prephase) received chemotherapy plus six courses of nelarabine 400 mg/m2 once per day; four patients with SER by high minimal residual disease (MRD; ≥ 1% at day 36 of induction) received chemotherapy plus five courses of nelarabine; 16 patients with a rapid early response (RER) received chemotherapy without nelarabine. In stage two, all patients received six 5-day courses of nelarabine at 650 mg/m2 once per day (10 SER patients [one by MRD, nine by PPR]) or 400 mg/m2 once per day (38 RER patients; 12 SER patients [three by MRD, nine by PPR]). Results The only significant difference in toxicities was decreased neutropenic infections in patients treated with nelarabine (42% with v 81% without nelarabine). Five-year event-free survival (EFS) rates were 73% for 11 stage one SER patients and 67% for 22 stage two SER patients treated with nelarabine versus 69% for 16 stage one RER patients treated without nelarabine and 74% for 38 stage two RER patients treated with nelarabine. Five-year EFS for all patients receiving nelarabine (n = 70) was 73% versus 69% for those treated without nelarabine (n = 16). Conclusion Addition of nelarabine to a BFM 86–based chemotherapy regimen was well tolerated and produced encouraging results in pediatric patients with T-ALL, particularly those with a SER, who have historically fared poorly.

    New chemotherapy regimens are continuously explored in patients with high-risk malignant germ cell tumours (MGCTs). This multicentre phase II trial assessed the efficacy and toxicity of C-BOP/BEP chemotherapy in intermediate and poor prognosis MGCT (IGCCCG criteria). C-BOP/BEP treatment consisted of cycles of cisplatin, vincristine, bleomycin and carboplatin, followed by one cycle of vincristine and bleomycin and three cycles of BEP (bleomycon, etoposide, cisplatin). The trial was designed to demonstrate a 1-year progression-free survival rate of 80%, that is, to exclude a 1-year rate of 70% or less, with a one-sided significance level of 5%. Secondary end points included toxicity, overall survival and the postchemotherapy complete response rate. In total, 16 European hospitals entered 66 eligible patients (intermediate prognosis group: 37; poor prognosis group: 29). A total of 45 patients (68.2%, 95% confidence interval (95% CI): 56.9–79.4%) achieved a complete response (intermediate prognosis: 30; poor prognosis: 15). After a median observation time of 40.4 months (range: 13.7–66.3), the 1-year progression-free survival rate was 81.8% 95% CI: 72.5–91.1%). The 2-year overall survival was 84.5% (95% CI: 75.6–93.3%). In all, 51 patients experienced at least one episode of WHO grade 3/4 leucopenia, and at least one event of grade 3/4 thrombocytopenia occurred in 30 patients. There was no toxic death. With an 82% 1-year progression-free survival and a lower limit of the 95% CI above 70%, the efficacy of C-BOP/BEP is comparable to that of published alternative chemotherapy schedules in high-risk MGCT patients. The treatment's toxicity is manageable in a multicentre setting. In poor prognosis patients, C-BOP/BEP should be compared to standard chemotherapy of four cycles of BEP. PMID:16251877

    Background Patients <60 years old with high-risk diffuse large B-cell lymphoma (DLBCL) receiving standard RCHOP(E) treatment display high relapse rates. Here, we compared this standard regimen to a high-intensity regimen in terms of recurrence and long-term survival. Material/Methods Newly diagnosed DLBCL patients <60 years old who were treated at the Second Hospital Affiliated with Xi’an Jiaotong University between January 2004 and December 2013 (n=198, 18–60 years) were included in the study. The high-intensity group included 107 patients (54.0%) who received >8 courses of chemotherapy (high-dose CHOP, CHOP-E, EPOCH, MAED, MMED, and HyperCVAD). The control group included 91 patients (46.0%) who received 6–8 courses of CHOP-based treatment. Response rate (RR), survival, relapse, and adverse effects were compared. Results Baseline characteristics of the patients were similar between the 2 groups. Median follow-up was 64.5 months. RR in the high-intensity and control groups was 88.8% and 84.6% (P=0.387), respectively; 5-year overall survival was 66.4% and 36.3% (P<0.001), respectively; 5-year progression-free survival was 56.1% and 28.6% (P<0.001), respectively; 5-year disease-free survival was 54.2% and 24.2% (P<0.001), respectively; and relapse rate during follow-up was 29.5% and 67.5% (P<0.001), respectively. There were no significant differences in adverse effects between the 2 groups. Conclusions High-intensity chemotherapy is associated with better prognosis of patients <60 years old with newly diagnosed high-risk DLBCL. PMID:27232105

    Purpose The five point Deauville (D) scale is widely used to assess interim PET metabolic response to chemotherapy in Hodgkin lymphoma (HL) patients. An International Validation Study reported good concordance among reviewers in ABVD treated advanced stage HL patients for the binary discrimination between score D1,2,3 and score D4,5. Inter-reader reliability of the whole scale is not well characterised. Methods Five international expert readers scored 100 interim PET/CT scans from paediatric HL patients. Scans were acquired in 51 European hospitals after two courses of OEPA chemotherapy (according to the EuroNet-PHL-C1 study). Images were interpreted in direct comparison with staging PET/CTs. Results The probability that two random readers concord on the five point D score of a random case is only 42% (global kappa = 0.24). Aggregating to a three point scale D1,2 vs. D3 vs. D4,5 improves concordance to 60% (kappa = 0.34). Concordance if one of two readers assigns a given score is 70% for score D1,2 only 36% for score D3 and 64% for D4,5. Concordance for the binary decisions D1,2 vs. D3,4,5 is 67% and 86% for D1,2,3 vs D4,5 (kappa = 0.36 resp. 0.56). If one reader assigns D1,2,3 concordance probability is 92%, but only 64% if D4,5 is called. Discrepancies occur mainly in mediastinum, neck and skeleton. Conclusion Inter-reader reliability of the five point D-scale is poor in this interobserver analysis of paediatric patients who underwent OEPA. Inter-reader variability is maximal in cases assigned to D2 or D3. The binary distinction D1,2,3 versus D4,5 is the most reliable criterion for clinical decision making. PMID:26963909

    Docetaxel is an antineoplastic drug from the taxane family that inhibits tubulin polymerization. Its brand name is Taxotere. In mid-2010, the formulation of Taxotere changed from a two-vial preparation needing a predilution (T2V) to a one-vial ready-to-use preparation (T1V). The aim of this study was to compare the toxicity profile of these two formulations. This retrospective observational and monocentric study included all patients who received Taxotere-based chemotherapy (100 mg/m) as an adjuvant or a neoadjuvant treatment for localized breast cancer, following initial treatment with anthracycline-based chemotherapy. Patients received either T2V or T1V Taxotere depending on the period of treatment. The main endpoint was the ratio of the dose of Taxotere received to that scheduled (R=docetaxel dose received/docetaxel dose scheduled). The secondary endpoint was tolerance. A total of 97 patients were included: 39 in the T2V group and 58 in the T1V group. The ratio of docetaxel received/docetaxel scheduled was significantly lower in the T1V than in the T2V group (0.83 vs. 0.95, respectively; P=0.028). A higher proportion of patients did not receive the totality of the scheduled dose in the T1V than in the T2V group (28 vs. 8%, respectively; P=0.03). Furthermore, the proportion of patients experiencing cutaneous toxicity was significantly higher in the T1V than in the T2V group (50 vs. 15%, respectively; P<0.001) as well as for neurological toxicity (31 vs. 15%, respectively; P=0.03). The frequency of grade 3 toxicities was higher in the T1V than in the T2V group (50 vs. 8%, P=0.016). The frequency of idiosyncratic toxicities was not affected by the change of formulation (4.7 vs. 5.4%, P=0.98). This study shows that patients treated with the T1V formulation received a significantly smaller dose of Taxotere than patients treated with T2V. In this small retrospective study, no conclusions can be drawn as to why a change in formulation would be associated with

    (131)I-Metaiodobenzylguanidine ((131)I-MIBG) has been used as a single agent or in combination with chemotherapy for the treatment of high-risk neuroblastoma. The activity and toxicity of (131)I-MIBG when combined with carboplatin, etoposide, and melphalan (CEM) and autologous stem cell transplantation (SCT) are now investigated in a phase II multicenter study. Fifty patients with MIBG-avid disease were enrolled into 2 cohorts, stratified by response to induction therapy. The primary study endpoint was response of patients with refractory (n = 27) or progressive disease (n = 15). A second cohort of patients (n = 8) with a partial response (PR) to induction therapy was included to obtain preliminary response data. (131)I-MIBG was administered on day -21 to all patients, with CEM given days -7 to -4, and SCT given on day 0. (131)I-MIBG dosing was determined by pre-therapy glomerular filtration rate (GFR), with 8 mCi/kg given if GFR was 60 to 99 mL/minute/1.73 m(2) (n = 13) and 12 mCi/kg if GFR ≥ 100 mL/minute/1.73 m(2) (n = 37). External beam radiotherapy was delivered to the primary and metastatic sites, beginning approximately 6 weeks after SCT. Responses (complete response + PR) were seen in 4 of 41 (10%) evaluable patients with primary refractory or progressive disease. At 3 years after SCT, the event-free survival (EFS) was 20% ± 7%, with overall survival (OS) 62% ± 8% for this cohort of patients. Responses were noted in 3 of 8 (38%) of patients with a PR to induction, with 3-year EFS 38% ± 17% and OS 75% ± 15%. No statistically significant difference was found comparing EFS or OS based upon pre-therapy GFR or disease cohort. Six of 50 patients had nonhematologic dose-limiting toxicity (DLT); 1 of 13 in the low GFR and 5 of 37 in the normal GFR cohorts. Hepatic sinusoidal obstructive syndrome (SOS) was seen in 6 patients (12%), with 5 events defined as dose-limiting SOS. The median times to neutrophil and platelet engraftment were 10 and 15 days

    Background Schistosomiasis has decreased significantly in prevalence and intensity of infection in China, thus more accurate and sensitive methods are desperately needed for the further control of schistosomiasis. The present work aimed to assess the utility of the loop-mediated isothermal amplification (LAMP) for detection of light intensity infection or false-negative patients and patients post-treatment, targeting the highly repetitive retrotransposon SjR2 of Schistosoma japonicum. Methodology/ Principal Findings LAMP was first assessed in rabbits with low intensity infection (EPG<10). Then 110 patient sera from Hunan Province, China, and 47 sera after treatment by praziquantel were used to evaluate the diagnostic validity of LAMP. Meanwhile, 42 sera from healthy individuals in a non-endemic area, and 60 sera from "healthy” residents who were identified as being negative for feces examination and immuno-methods in an endemic area were also examined. The results showed that LAMP could detect S. japonicum DNA in sera from rabbits at 3rd day post-infection. Following administration of praziquantel, the S. japonicum DNA in rabbit sera became negative at 10 weeks post-treatment. Of 110 sera from patients, LAMP showed 95.5% sensitivity, and even for 41 patients with less than 10 EPG, the sensitivity of LAMP still reached to 95.1%. For 47 patients after treatment, the negative conversion rate of S. japonicum DNA in patient sera increased from 23.4%, 61.7% to 83.0% at 3 months, 6 months and 9 months post-treatment, respectively. No false-positive result was obtained for 42 human sera from non-endemic area, while for the 60 “healthy” individuals from endemic area, 10 (16.7%) individuals were positive by LAMP, which suggested that these individuals might be false-negative patients. Conclusions/ Significance The present study demonstrated that the LAMP assay is sensitive, specific, and affordable, which would help reduce schistosomiasis transmission through targeted

    Purpose: To describe voice and speech quality changes and their predictors in patients with locally advanced oropharyngeal cancer treated on prospective clinical studies of organ-preserving chemotherapy–intensity modulated radiation therapy (chemo-IMRT). Methods and Materials: Ninety-one patients with stage III/IV oropharyngeal cancer were treated on 2 consecutive prospective studies of definitive chemoradiation using whole-field IMRT from 2003 to 2011. Patient-reported voice and speech quality were longitudinally assessed from before treatment through 24 months using the Communication Domain of the Head and Neck Quality of Life (HNQOL-C) instrument and the Speech question of the University of Washington Quality of Life (UWQOL-S) instrument, respectively. Factors associated with patient-reported voice quality worsening from baseline and speech impairment were assessed. Results: Voice quality decreased maximally at 1 month, with 68% and 41% of patients reporting worse HNQOL-C and UWQOL-S scores compared with before treatment, and improved thereafter, recovering to baseline by 12-18 months on average. In contrast, observer-rated larynx toxicity was rare (7% at 3 months; 5% at 6 months). Among patients with mean glottic larynx (GL) dose ≤20 Gy, >20-30 Gy, >30-40 Gy, >40-50 Gy, and >50 Gy, 10%, 32%, 25%, 30%, and 63%, respectively, reported worse voice quality at 12 months compared with before treatment (P=.011). Results for speech impairment were similar. Glottic larynx dose, N stage, neck dissection, oral cavity dose, and time since chemo-IMRT were univariately associated with either voice worsening or speech impairment. On multivariate analysis, mean GL dose remained independently predictive for both voice quality worsening (8.1%/Gy) and speech impairment (4.3%/Gy). Conclusions: Voice quality worsening and speech impairment after chemo-IMRT for locally advanced oropharyngeal cancer were frequently reported by patients, underrecognized by clinicians, and

    We previously reported that the local control of pulmonary metastases from colorectal cancer (CRC) following stereotactic body radiotherapy (SBRT) with moderate prescription dose was relatively worse. We investigated the treatment outcomes and toxicities of patients with oligometastases from CRC treated by SBRT using risk-adapted, very high- and convergent-dose regimens. Among patients referred for SBRT from August 2011 to January 2015, those patients were extracted who had liver or pulmonary metastases from CRC, and they were treated with a total dose of 50–60 Gy in five fractions prescribed to the 60% isodose line of the maximum dose covering the surface of the planning target volume. Concurrent administration of chemotherapy was not admitted during SBRT, while neoadjuvant or adjuvant chemotherapy was allowed. A total of 21 patients (12 liver, 9 lung) with 28 oligometastases were evaluated. The median follow-up duration was 27.5 months (range: 6.5–43.3 months). Four patients were treated with SBRT as a series of initial treatments, and 17 patients were treated after recurrent oligometastases. The local control rates at 1 and 2 years from the start of SBRT were 100%. The disease-free and actuarial overall survival rates were 62% and 55%, and 79% and 79%, respectively. No severe toxicities (≥grade 3) occurred during follow-up. The outcomes following high-dose SBRT were excellent. This treatment can provide an alternative to the surgical resection of oligometastases from CRC. Prospective studies are needed to validate the effectiveness of SBRT. PMID:26983981

    The European Society for Blood and Marrow Transplant Research data set was used to retrospectively analyze the outcomes of hypomethylating therapy (HMA) compared with those of conventional chemotherapy (CC) before hematopoietic stem cell transplantation (HSCT) in 209 patients with advanced myelodysplastic syndromes. Median follow-up was 22.1 months and the median age of the group was 57.6 years with 37% of the population older than > 60 years. The majority of patients (59%) received reduced-intensity conditioning and 34% and 27% had intermediate-2 and high international prognostic scoring system (IPSS) scores. At time of HSCT, 32% of patients did not achieve complete remission (CR) and 13% had primary refractory disease. On univariate analysis, outcomes at 3 years were not significantly different between HMA and CC for overall survival (OS), relapse-free survival (RFS), cumulative incidence of relapse (CIR), and nonrelapse mortality (NRM): OS (42% versus 35%), RFS (29% versus 31%), CIR (45% versus 40%), and NRM (26% versus 28%). Comparing characteristics of the groups, there were more patients < 55 years old, more patients in CR (68% versus 32%), and fewer patients with primary refractory disease in the CC group than in the HMA group (10% versus 19%, P < .001). Patients with primary refractory disease had worse outcomes than those in CR with regard to OS (hazard ratio [HR], 2.42; 95% confidence interval [CI], 1.41 to 4.13; P = .001), RFS (HR, 2.27; 95% CI, 1.37 to 3.76; P = .001), and NRM (HR, 2.49; 95% CI, 1.18 to 5.26; P = .016). In addition, an adverse effect of IPSS-R cytogenetic risk group was evident for RFS. In summary, outcomes after HSCT are similar for patients receiving HMA compared with those receiving CC, despite the higher proportion of patients with primary refractory disease in the HMA group.

    The surgical morbidity associated with aggressive preoperative chemotherapy in 106 patients with advanced primary breast cancer who had chemotherapy followed by mastectomy was examined. These patients were compared with a group of 91 consecutive patients who had mastectomy without preoperative chemotherapy. Strict operative criteria were used to determine the timing of mastectomy following chemotherapy. Wound infection rates were no different in the preoperative chemotherapy group compared to the mastectomy-alone groups (7% versus 4%; p = 0.62). The incidence of wound necrosis was similar (11% versus 6%; p = 0.29). Seroma formation was decreased significantly in the preoperative chemotherapy group compared to the mastectomy-alone group (15% versus 28%; p = 0.04). Intensive preoperative chemotherapy did not delay the reinstitution of postoperative treatment (30% versus 20%; p = 0.27). However, when delay in instituting postoperative chemotherapy was more than 30 days, there was a significant decrease in overall survival rate (p = 0.04). This study provides evidence that intensive preoperative chemotherapy and mastectomy can be performed without increased morbidity. Furthermore it is important to institute systemic chemotherapy within 30 days of mastectomy to achieve maximum survival. PMID:1992938

    The project RiskAdapt, funded by the Climate and Energy Fund Austria, applies a novel dynamic flood risk assessment approach. It analyses both aspects of risk - hazard and vulnerability - and considers their potential spatial and temporal developments under climate change scenarios on a macro scale (federal territory of Austria) and a micro scale (regional/local case studies). The conceptual framework of RiskAdapt integrates analytical perspectives of hazard and vulnerability, the latter comprising the analysis of exposure, sensitivity and adaptive capacities. In the framework of the macro scale risk assessment, a nationwide GIS based analysis of current hazard exposure is conducted based on the indicators "affected persons" and "traffic infrastructure" (roads and railroads) in calculated flooding areas. Provided by the Environment Agency Austria (UBA) for 500m river stretches, these indicators are evaluated for each municipality in Austria. To assess their future exposure to flood hazards, demographic and land-use change scenarios (timeframe: 2030) are established based on existing projections and available data suitable for extrapolation. Regarding population change, extrapolations of local demographic developments are correlated with regional forecasts provided by the Austrian Conference on Spatial Planning (ÖROK). Land-use change scenarios are established by extrapolating trends in the development of highly vulnerable land uses (including building land for housing, commercial and industrial purposes as well as land used for traffic infrastructure). Data on highly vulnerable land uses is available for the years 2001, 2003, 2005 and 2012 for each municipality of Austria (provided by UBA). Based on this analysis, municipalities will be clustered according to the present and expected degree of exposure. This simplified approach in exposure assessment contains uncertainties, in particular with regard to demographic and land-use change scenarios: -) While population

    For approximately a decade, chemotherapy has been shown to prolong life in patients with metastatic castration-resistant prostate cancer (mCRPC). Since that time, however, only two agents have proven to prolong life (docetaxel and cabazitaxel). However, in the last year, the addition of chemotherapy to primary hormonal therapy became a standard of care for high-volume castration-sensitive metastatic disease. Here I will review current prostate cancer chemotherapies, mechanisms of resistance to those therapies, and ongoing clinical studies of chemotherapy combinations and novel chemotherapeutics.

    Chemotherapy may have detrimental effects on either the central or peripheral nervous system. Central nervous system neurotoxicity resulting from chemotherapy manifests as a wide range of clinical syndromes including acute, subacute, and chronic encephalopathies, posterior reversible encephalopathy, acute cerebellar dysfunction, chronic cognitive impairment, myelopathy, meningitis, and neurovascular syndromes. These clinical entities vary by causative agent, degree of severity, evolution, and timing of occurrence. In the peripheral nervous system, chemotherapy-induced peripheral neuropathy (CIPN) and myopathy are the two main complications of chemotherapy. CIPN is the most common complication, and the majority manifest as a dose-dependent length-dependent sensory axonopathy. In severe cases of CIPN, the dose of chemotherapy is reduced, the administration delayed, or the treatment discontinued. Few treatments are available for CIPN and based on meta-analysis, duloxetine is the preferred symptomatic treatment. Myopathy due to corticosteroid use is the most frequent cause of muscle disorders in patients with cancer. PMID:27443648

    The two combination chemotherapy regimens FOLFIRINOX and gemcitabine plus nab-paclitaxel represent major breakthroughs in the management of metastatic pancreatic cancer. Both regimens showed unprecedented survival advantage in the setting of front-line therapy. However, their application for treatment of patients in the community is challenging because of significant toxicities, thus limiting potential benefits to a narrow population of patients. Modifications to the dose intensity or schedule of those regimens improve their tolerability, while likely retaining survival advantage over single-agent chemotherapy. Newer strategies to optimize these two active regimens in advanced pancreatic cancer are being explored that can help personalize treatment to individual patients. PMID:26939741

    Eleven children with metastatic retinoblastoma diagnosed during the period 1970-1984 were treated with chemotherapy. Short-term complete responses were observed in three children treated with a four-drug combination which included cisplatinum, and in one child treated with vincristine and cyclophosphamide. The median duration of survival of the 11 children receiving chemotherapy was nine months, whilst the median survival of 13 children with metastatic retinoblastoma who were not given chemotherapy was only 2.3 months (p = 0.06). This suggests that retinoblastoma is a chemosensitive tumour and therefore adjuvant chemotherapy may have a role in children with retinoblastoma who at diagnosis are thought to be at high risk of developing metastatic disease.

    Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) combined have been recognized as standard of care for treatment of a subset of patients with peritoneal carcinomatosis (PC). The aim of CRS is to eliminate all macroscopic disease through a series of visceral resections followed by targeting any residual microscopic disease with intraperitoneal chemotherapy, exposing the peritoneal surfaces to a high concentration of chemotherapy with a lower systemic toxicity. Different regimes of intraperitoneal chemotherapy include HIPEC, early postoperative intraperitoneal chemotherapy (EPIC) and bidirectional chemotherapy. The efficacy and modality of treatment with intraperitoneal chemotherapy is dependent on multiple factors including the chosen cytotoxic agent and its pharmacokinetics and pharmacodynamics. There is no standardized methodology for intraperitoneal chemotherapy administration. This review will discuss the pharmacological principles of the various intraperitoneal chemotherapy techniques.

    Purpose: The role of radiotherapy (RT) after intensive chemotherapy in patients with advanced stage Hodgkin's lymphoma (HL) is still unclear. The German Hodgkin Study Group (GHSG) randomized HD12 trial was designed to test whether consolidative RT in the region of initial bulky disease and of residual disease is necessary after effective chemotherapy. A quality control program based on a multidisciplinary panel of radiation oncologists, radiologists, and medical oncologists who reviewed all patients' staging and restaging imaging was initiated. Methods and Materials: A total of 1661 patients aged 16 to 65 years with HL in Stage IIB (large mediastinal mass and/or E-lesions) or Stage III to IV were randomized from January 1999 to January 2003 according to a factorial design between: 8 esc.BEACOPP + RT (arm A), 8 esc.BEACOPP non-RT (arm B), 4+4BEACOPP + RT (arm C), 4+4BEACOPP non-RT (arm D). Results: In the fifth interim analysis, 1449 patients were eligible for the arm comparison with regard to RT. After a median observation time of 48 months the FFTF rate was 86% and the OS 92%. The FFTF was 95% in the RT arms A+C and 88% in the non-RT arms B+D: no sequential significant difference. One thousand and eighty four patients were evaluated by the panel. The panel defined initial bulky disease in 800 patients and residual disease in 600 patients. The panel recommended continuation of therapy according to the randomization for 934 of 1084 patients and additive RT independently from the randomization arm for 145 of 1084 patients. Conclusions: The study showed that RT can be reduced substantially after effective chemotherapy. However, because of the irradiation of 10% of patients in the non-RT arms, equivalent effectiveness of a non-RT strategy cannot be proved. A substantial limitation of consolidative RT according to expert panel recommendations appears to be possible without reducing effectiveness.

    Background About one half of adults with acute lymphoblastic leukemia are not cured of the disease and ultimately die. The objective of this study was to explore the factors influencing the outcome of adult patients with relapsed acute lymphoblastic leukemia. Design and Methods We analyzed the characteristics, the outcome and the prognostic factors for survival after first relapse in a series of 263 adult patients with acute lymphoblastic leukemia (excluding those with mature B-cell acute lymphoblastic leukemia) prospectively enrolled in four consecutive risk-adapted PETHEMA trials. Results The median overall survival after relapse was 4.5 months (95% CI, 4–5 months) with a 5-year overall survival of 10% (95% CI, 8%–12%); 45% of patients receiving intensive second-line treatment achieved a second complete remission and 22% (95% CI, 14%–30%) of them remained disease free at 5 years. Factors predicting a good outcome after rescue therapy were age less than 30 years (2-year overall survival of 21% versus 10% for those over 30 years old; P<0.022) and a first remission lasting more than 2 years (2-year overall survival of 36% versus 17% among those with a shorter first remission; P<0.001). Patients under 30 years old whose first complete remission lasted longer than 2 years had a 5-year overall survival of 38% (95% CI, 23%–53%) and a 5-year disease-free survival of 53% (95% CI, 34%–72%). Conclusions The prognosis of adult patients with acute lymphoblastic leukemia who relapse is poor. Those aged less than 30 years with a first complete remission lasting longer than 2 years have reasonable possibilities of becoming long-term survivors while patients over this age or those who relapse early cannot be successfully rescued using the therapies currently available.

    Purpose: High local control rates can be achieved using stereotactic radiotherapy in Stage I non-small-cell lung cancer (NSCLC), but reports have suggested that toxicity may be of concern. We evaluated early clinical outcomes of 'risk-adapted' fractionation schemes in patients treated in a single institution. Methods and Materials: Of 206 patients with Stage I NSCLC, 81% were unfit to undergo surgery and the rest refused surgery. Pathologic confirmation of malignancy was obtained in 31% of patients. All other patients had new or growing 18F-fluorodeoxyglucose positron emission tomography positive lesions with radiologic characteristics of malignancy. Planning four-dimensional computed tomography scans were performed and fractionation schemes used (3 x 20 Gy, 5 x 12 Gy, and 8 x 7.5 Gy) were determined by T stage and risk of normal tissue toxicity. Results: Median overall survival was 34 months, with 1- and 2-year survivals of 81% and 64%, respectively. Disease-free survival (DFS) at 1 and 2 years was 83% and 68%, respectively, and DFS correlated with T stage (p = 0.002). Local failure was observed in 7 patients (3%). The crude regional failure rate was 9%; isolated regional recurrence was observed in 4%. The distant progression-free survival at 1 and 2 years was 85% and 77%, respectively. SRT was well tolerated and severe late toxicity was observed in less than 3% of patients. Conclusions: SRT is well tolerated in patients with extensive comorbidity with high local control rates and minimal toxicity. Early outcomes are not inferior to those reported for conventional radiotherapy. In view of patient convenience, such risk-adapted SRT schedules should be considered treatment of choice in patients presenting with medically inoperable Stage I NSCLC.

  6. Design of the EXercise Intervention after Stem cell Transplantation (EXIST) study: a randomized controlled trial to evaluate the effectiveness and cost-effectiveness of an individualized high intensity physical exercise program on fitness and fatigue in patients with multiple myeloma or (non-) Hodgkin's lymphoma treated with high dose chemotherapy and autologous stem cell transplantation

    PubMed Central

    2010-01-01

    Background The use of high-dose chemotherapy combined with autologous stem cell transplantation has improved the outcome of hematologic malignancies. Nevertheless, this treatment can cause persistent fatigue and a reduced global quality of life, role and physical function. Physical exercise interventions may be beneficial for physical fitness, fatigue and quality of life. However, the trials conducted so far to test the effects of physical exercise interventions in this group of patients were of poor to moderate methodological quality and economic evaluations are lacking. Hence there is need for a rigorous, appropriately controlled assessment of the effectiveness of exercise programs in these patients. The aims of the present study are (1) to determine the effectiveness of an individualized high intensity strength and interval training program with respect to physiological and psychological health status in patients with multiple myeloma or (non-)Hodgkin's lymphoma who have recently undergone high dose chemotherapy followed by autologous stem cell transplantation; and (2) to evaluate the cost-effectiveness of this program. Methods A multicenter, prospective, single blind randomized controlled trial will be performed. We aim to recruit 120 patients within an inclusion period of 2 years at 7 hospitals in the Netherlands. The patients will be randomly assigned to one of two groups: (1) intervention plus usual care; or (2) usual care. The intervention consists of an 18-week individualized supervised high-intensity exercise program and counselling. The primary outcomes (cardiorespiratory fitness, muscle strength and fatigue) and secondary outcomes are assessed at baseline, at completion of the intervention and at 12 months follow-up. Discussion The strengths of this study include the solid trial design with clearly defined research groups and standardized outcome measures, the inclusion of an economic evaluation and the inclusion of both resistance and endurance

    The overall increase in cancer prevalence and the significant increase in long-term survival have generated worldwide interest in preserving fertility in young women exposed to gonadotoxic chemo- and radiotherapy. Infertility represents one of the main long-term consequences of combination chemotherapy given for lymphoma, leukaemia and other malignancies in young women. The gonadotoxic effect of various chemotherapeutic agents is diverse, may involve a variety of pathophysiologic mechanisms, and is not unequivocally understood. Proliferating cells, such as in tissues with high turnover (i.e. bone marrow, gastrointestinal tract and growing ovarian follicles) are more vulnerable to the toxic effect of alkylating agents. These agents may also be cytotoxic to cells at rest, as they are not cell-cycle specific. Alkylating agents, the most gonadotoxic chemotherapeutic medications, cause dose-dependent, direct destruction of oocytes and follicular depletion, and may bring about cortical fibrosis and ovarian blood-vessel damage. The reported rate of premature ovarian failure after various diseases and chemotherapeutic protocols differ enormously, and depend mainly on the chemotherapeutic protocol used and age range of the woman. Several options have been proposed for preserving female fertility, despite gonadotoxic chemotherapy: ovarian transposition, cryopreservation of embryos, unfertilised metaphase-II oocytes and ovarian tissue, and administration of gonadotropin-releasing hormone agonistic analogs in an attempt to decrease the gonadotoxic effects of chemotherapy by simulating a prepubertal hormonal milieu. None of these methods is ideal and none guarantees future fertility in all survivors; therefore, a combination of methods is recommended for maximising women's chances of future fertility.

    Androgen deprivation in patients with metastatic prostate cancer produces palliation of symptoms, PSA decrease and tumoral regression in most patients. After a brief period of disease regression lasting 18 to 24 months nearly all pts will progress to androgen independence disease (HRPC) with progressive clinical deterioration and ultimately death. Chemotherapy with mitoxantrone has been shown to palliate symptoms but did not extend survival. Two large randomized trials showed a survival benefit for pts with HRPC treated with docetaxel with a reduction risk of death by 21-24%, and significant improvement in palliation of symptoms and quality of life. New agents targeting angiogenesis, apoptosis, signal transduction pathway, used alone or in combination with docetaxel currently are under trial in an attempt to provide much needed improvements in outcome. Questions remains in suspend when and who need to be treated, earlier, in high risk as in adjuvant setting? Current data have demonstrated that neoadjuvant or adjuvant chemotherapy is relatively safe and feasible. Further investigation through prospective randomize trials is critical to define the precise role of this modality in high risk populations. PMID:17845990

    The improvements in cancer detection and therapy have created a new cohort of patients who will experience sufficient survival to develop the cardiac complications of the cancer therapy. Three-dimensional echocardiography has been validated as the ultrasound modality with the best accuracy for the calculation of ejection fraction when compared to magnetic resonance imaging, the current gold standard, making it the tool of choice, when available, for the initial evaluation and follow up of the patient receiving chemotherapy. If three-dimensional echocardiography is not available, or if the quality of the images is inadequate, the use of ultrasound contrast can be useful for the definition of the endocardial border and identification of the true apex of the heart, enhancing the ability of the interpreter to accurately calculate volumes and ejection fraction. Two-dimensional strain appears promising as a tool to identify abnormalities in myocardial mechanics very early on during cardiotoxicity, allowing the prediction of later overt systolic dysfunction. This parameter may be useful in the detection of chemotherapy treated patients who could benefit from alternate therapies, thereby decreasing the incidence of cardiotoxicity and its associated morbidity and mortality.

    The risk and mechanism of chemotherapy-induced cardiotoxicity (CTX) vary depending on the type and intensity of the anticancer regimen. Myriad chemotherapeutic drugs produce adverse cardiovascular effects such as arterial hypertension, heart failure, and thromboembolic events. Among the numerous classes of these drugs, anthracyclines have been studied most extensively because of their overt cardiovascular effects and the high associated incidence of heart failure. However, CTX might also be caused by other types of chemotherapeutic agents, including alkylating agents (cyclophosphamide, ifosfamide), platinum agents, antimetabolites (5-fluorouracil, capecitabine), antibiotics (mitoxantrone, mitomycin, bleomycin), and antimicrotubule agents (taxanes). Here, we review the incidence, clinical impact, and potential mechanisms of CTX associated with nonanthracycline chemotherapy used for cancer patients. The published data support a marked increase in CTX risk, particularly with certain drugs such as 5-fluorouracil and cisplatin. Each anticancer regimen is associated with distinct modes of heart damage, both symptomatic and asymptomatic. However, the underlying mechanisms of CTX have been established only in a few cases, and only few nonanthracycline chemotherapeutics (mitoxantrone, mitomycin, ifosfamide) act through a recognizable mechanism and show a predictable dose dependence. Lastly, nonanthracycline chemotherapy can induce both chronic lesions, such as systolic dysfunction, and acute lesions, such as the ischemia that occurs within hours or days after treatment. An increased understanding of the incidence, mechanisms, and potential therapeutic targets of CTX induced by various nonanthracycline chemotherapeutic agents is clearly required. PMID:27183520

    While radiotherapy and antineoplastic chemotherapy often control malignancies they may, paradoxically, cause new cancers to develop as long-term complications. Although almost any type of neoplasm can occur, radiation-induced malignancies are most likely to affect the myelopoietic tissues and the thyroid gland. The former tissues are also most frequently involved by chemotherapy. The combination of intensive radiotherapy and intensive chemotherapy is particularly leukemogenic. Acute myeloid leukemia has occurred with increased frequency following treatment of Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, ovarian cancer, polycythemia vera, carcinoma of the thyroid gland, and carcinoma of the breast. Radiation-induced malignancies usually occur in the field of irradiation. Tumors developing in an irradiated field include a substantial number of soft tissue sarcomas or osteosarcomas. There is a 20-fold increase of second cancers following treatment of childhood malignancies, mostly sarcomas of bone and soft tissues, but including leukemia, and carcinomas of the thyroid gland, skin, and breast. The latent period between radiotherapy and the appearance of a second cancer ranges from 2 years to several decades, often being 10-15 years. With chemotherapy the mean latent period is shorter, approximately 4 years. The mechanism of oncogenesis by radiotherapy or chemotherapy is poorly understood and probably involves a complex interplay of somatic mutation, co-oncogenic effects, depression of host immunity, stimulation of cellular proliferation, and genetic susceptibility.

    Conventional chemotherapy is the main treatment for cancer and benefits patients in the form of decreased relapse and metastasis and longer overall survival. However, as the target therapy drugs and delivery systems are not wholly precise, it also results in quite a few side effects, and is less efficient in many cancers due to the spared cancer stem cells, which are considered the reason for chemotherapy resistance, relapse, and metastasis. Conventional chemotherapy limitations and the cancer stem cell hypothesis inspired our search for a novel chemotherapy targeting cancer stem cells. In this review, we summarize cancer stem cell enrichment methods, the search for new efficient drugs, and the delivery of drugs targeting cancer stem cells. We also discuss cancer stem cell hierarchy complexity and the corresponding combination therapy for both cancer stem and non-stem cells. Learning from cancer stem cells may reveal novel strategies for chemotherapy in the future. PMID:26045975

    "If we are not careful, we soon will be in the post-antibiotic era, and for some patients and some microbes we are already there"- Tom Friedan Antibiotics revolutionized medicine in the 20th century. The era of antibacterial chemotherapy began in 1907 with the discovery of arsphenamine, first synthesized by Alferd Bertheim and Paul Ehrlich in 1907, used to treat syphilis. The first systemically active antibiotic, Prontosil was discovered in 1933 by Gerhard Domagk, for which he was awarded the 1939 Nobel Prize. Fleming's accidental discovery and isolation of penicillin in September 1928 marked the start of modern antibiotics. It was a discovery that changed the course of history and saved millions of lives.

    Objective To describe the effects of obesity on the pharmacokinetics and dosing of chemotherapies and provide recommendations for chemotherapy management in obese women with gynecologic malignancies. Methods PubMEd and MEDLINE databases were searched for articles published before June 2014. Only English-language articles were considered. 84 manuscripts were reviewed and 66 were included. Search terms included: obesity, overweight, body mass index, body surface area, glomerular filtration rate, chemotherapy, ovarian cancer, endometrial cancer, inflammation, and pharmacokinetics, Results Obese cancer patients have worse clinical outcomes, compared with non-obese patients. This may be because of differences in pharmacokinetics, metabolic dysregulation, or physicians' decisions to reduce chemotherapy dose-intensity during treatment to minimize toxicities. A 2012 American Society of Clinical Oncology Clinical Practice Guideline recommends using actual body weight for chemotherapy dosing in all patients treated with curative intent, irrespective of obesity, to avoid compromising clinical outcomes, including progression free survival (PFS) and overall survival (OS). In women with gynecologic cancers most studies demonstrate no difference in PFS or OS when obese patients receive the same chemotherapy dose intensity as non-obese patients, except perhaps with bevacizumab. Conclusions Chemotherapy dose-intensity is a critical determinant of cancer outcomes and should be maintained in all patients, irrespective of obesity. Future studies should prospectively examine the impact of obesity on clinical outcomes (adverse events, survival) to improve the care of this growing population of patients who are at risk for inferior clinical outcomes.

    2012-01-01

    Treatment of cancer is associated with short- and long-term side-effects. Cancer produces a state of glutamine deficiency, which is further aggravated by toxic effects of chemotherapeutic agents leading to increased tolerance of tumor to chemotherapy as well as reduced tolerance of normal tissues to the side-effects of chemotherapy. This article reviews the possible role of glutamine supplementation in reducing the serious adverse events in patients treated with anticancer drugs. The literature related to the possible role of glutamine in humans with cancer and the supportive evidence from animal studies was reviewed. Searches were made and the literature was retrieved using PUBMED, MEDLINE, COCHRANE LIBRARY, CENAHL and EMBASE, with a greater emphasis on the recent advances and clinical trials. Glutamine supplementation was found to protect against radiation-induced mucositis, anthracycline-induced cardiotoxicity and paclitaxel-related myalgias/arthralgias. Glutamine may prevent neurotoxicity of paclitaxel, cisplatin, oxaplatin bortezomib and lenolidamide, and is beneficial in the reduction of the dose-limiting gastrointestinal toxic effects of irinotecan and 5-FU-induced mucositis and stomatitis. Dietary glutamine reduces the severity of the immunosuppressive effect induced by methotrexate and improves the immune status of rats recovering from chemotherapy. In patients with acute myeloid leukemia requiring parenteral nutrition, glycyl-glutamine supplementation could hasten neutrophil recovery after intensive myelosuppressive chemotherapy. Current data supports the usefulness of glutamine supplementation in reducing complications of chemotherapy; however, paucity of clinical trials weakens the clear interpretation of these findings.

    Patients with bony and soft tissue sarcomas may require intensive treatment with chemotherapy and radiotherapy, which often leads to a fall in haemoglobin levels, requiring blood transfusion. There may be advantages in predicting which patients will require transfusion, partly because anaemia and hypoxia may worsen the response of tumours to chemotherapy and radiotherapy. Between 1997 and 2003, a total of 26 patients who received intensive treatment with curative intent were identified. Transfusions were given to maintain the haemoglobin at 10g/dl or above during chemotherapy, and at 12 g/dl or above during radiotherapy. Eighteen (69%) required a transfusion, the majority as a result of both the chemotherapy and RT criteria. There were 78 transfusion episodes, and 181 units of blood given. In the 18 patients who required transfusion, the average number of units was 10.1, but seven patients required more blood than this. The most significant factor influencing blood transfusion was choice of intensive chemotherapy. Intensive chemotherapy and presenting Hb less than 11.6 g/dl identified 13 out of 18 patients who needed transfusion. Adding a drop in haemoglobin of greater than 1.7 g/dl after one cycle of chemotherapy identified 16 out of 18 patients who required transfusion. The seven patients who had heavy transfusion requirements were identified by age 32 or less, intensive chemotherapy and a presenting Hb of 12 g/dl or less. Erythropoietin might be a useful alternative to transfusion in selected patient groups, especially those with heavy transfusion requirements. PMID:18521418

    During the past 3 decades, chemotherapeutic agents have been extensively evaluated for the treatment of pediatric brain tumors in a myriad of schedules, doses, and combinations. Remarkable advances in outcome have been achieved for certain groups of children, notably those with medulloblastoma, and chemotherapy has played a key role. However, improvements in survival are obtained at a high cost to quality of life. In addition, the success achieved for medulloblastoma is offset by a lack of progress for high-grade glioma. Despite decades of intensive investigation, no single chemotherapeutic regimen stands out as particularly beneficial for children with high-grade glioma, with the vast majority of these patients succumbing to their disease. A plateau in efficacy has been reached. Further treatment intensification using conventional nonspecific chemotherapy is more likely to result in additional toxicity without major advances in survival. Genomewide analysis using microarray technology has contributed significantly to our understanding of tumor biology. This knowledge has shifted the focus onto novel agents that target molecular changes crucial for tumor proliferation or survival. These selective agents are likely to be less toxic to normal cells and it is anticipated they will be more effective than the nonspecific chemotherapeutic agents currently used. PMID:18952581

    Modern cancer therapy prolongs patients life but commonly increases incidence of treatment-related complications. One of such adverse effect is a neurotoxicity, which usually manifestates as peripheral neuropathies (CIPN), characterised by various sensory (tingling, numbness, pain), motor (foot and hands drop, fastening buttons difficulties) and autonomic (constipation, arythmia) abnormalities as well as pain. Despite of intensive epidemiological and clinical studies, standardized diagnostic criteria and methods of the neuropathy prevention and treatment have not been fully established. The most commonly used form of treatment is symptomatic therapy, including anticonvulsant and antidepressant drugs. Proper education of patients and their families of symptoms and neuropathy consequences is desirable to reduce anxiety and stress. PMID:24575651

    High-dose melphalan (MEL) with autologous stem cell transplant (SCT) is an effective therapy for systemic AL amyloidosis (AL), but treatment-related mortality (TRM) has historically been high. We performed a phase II trial of risk-adapted SCT followed by adjuvant dexamethasone (dex) and thalidomide (thal) in an attempt to reduce TRM and improve response rates. Patients (n = 45) with newly diagnosed AL involving < or =2 organ systems were assigned to MEL 100, 140, or 200 mg/m(2) with SCT, based on age, renal function and cardiac involvement. Patients with persistent clonal plasma cell disease 3 months post-SCT received 9 months of adjuvant thal/dex (or dex if there was a history of deep vein thrombosis or neuropathy). Organ involvement was kidney (67%), heart (24%), liver/GI (22%) and peripheral nervous system (18%), with 31% having two organs involved. TRM was 4.4%. Thirty-one patients began adjuvant therapy, with 16 (52%) completing 9 months of treatment and 13 (42%) achieving an improvement in haematological response. By intention-to-treat, overall haematological response rate was 71% (36% complete response), with 44% having organ responses. With a median follow-up of 31 months, 2-year survival was 84% (95% confidence interval: 73%, 94%). Risk-adapted SCT with adjuvant thal/dex is feasible and results in low TRM and high haematological and organ response rates in AL patients. PMID:17897298

    Multiple myeloma is a malignant plasma cell neoplasm that affects more than 20,000 people each year and is the second most common hematologic malignancy. It is part of a spectrum of monoclonal plasma cell disorders, many of which do not require active therapy. During the past decade, considerable progress has been made in our understanding of the disease process and factors that influence outcome, along with development of new drugs that are highly effective in controlling the disease and prolonging survival without compromising quality of life. Identification of well-defined and reproducible prognostic factors and introduction of new therapies with unique modes of action and impact on disease outcome have for the first time opened up the opportunity to develop risk-adapted strategies for managing this disease. Although these risk-adapted strategies have not been prospectively validated, enough evidence can be gathered from existing randomized trials, subgroup analyses, and retrospective studies to develop a working framework. This set of recommendations represents such an effort—the development of a set of consensus guidelines by a group of experts to manage patients with newly diagnosed disease based on an interpretation of the best available evidence.

    Unresectable cholangiocarcinoma is poorly responded to chemotherapy, especially for the case refractory to gemcitabine and cisplatin. Here, we tested whether high expression of thymidine phosphorylase (TP) can be a predictive biomarker for the indicator for gemcitabine and doxifluridine combination chemotherapy in the cholangiocarcinoma refractory to gemcitabine and cisplatin. Immunohistochemical staining for TP was performed with a biopsy specimen. We accepted the result as positive when more than 10% of cancer cells were stained with moderate intensity. Here, we report 2 cases of TP-positive cholangiocarcinoma well controlled with gemcitabine and doxifluridine combination chemotherapy, which had been refractory to the first line treatment with gemcitabine and cisplatin combination chemotherapy.

    Since there is no 100% satisfactory treatment for localized prostate cancer in patients presenting symptoms representing a poor prognosis (stage T3, high Gleason score, PSA level greater than 15 ng/ml, etc.), this study aimed to evaluate the therapeutic and synergistic inhibition effects of using High Intensity Focused Ultrasound (HIFU) in combination with chemotherapy (Taxane + Estramustine). Forty-one Dunning AT2 tumour-bearing Copenhagen rats receiving HIFU and/or chemotherapy were divided into four groups: control group; chemotherapy group; HIFU group; and HIFU-chemotherapy combined group. Increase in the tumour volume was observed over 3 weeks and the tumour volume doubling time was evaluated. Growth curves for each group were then plotted and statistically evaluated. HIFU treatment combined with Taxane + Estramusine was found to have a significant synergistic effect; on day 30, the distribution of tumour volume relative to the treatment group was significantly different (p = 0.0007). The control group volumes were significantly greater than those of the chemotherapy-only (p = 0.006) or HIFU-only group (p = 0.006). The greatest difference was observed between the chemotherapy plus HIFU combined group and the control group. Additionally, tumour-doubling times were 7.7 days for the control group, 13.2 days for the HIFU-only group, and 31.2 days for the chemotherapy plus HIFU group. The differences in tumour growth rates between the chemotherapy plus HIFU combined group and a chemotherapy-only + HIFU-only grouping was 3.8% (p = 0.0020). Thus, the combined chemotherapy plus HIFU treatment was clearly more effective in reducing the tumour size than HIFU only or chemotherapy only, which indicates a synergy between the two types of treatment. Our results suggest that this combined therapy could be useful for the treatment of high-risk prostate cancer.

  7. Lumbar reservoir for intrathecal chemotherapy.

    The Ommaya ventricular reservoir has been the standby of intrathecal chemotherapy for more than a decade, in spite of some specific drawbacks. A general anaesthetic is often required. The scalp must be shaven. Ventricular puncture may not always be easy and keeping the ventricular catheter patent is sometimes difficult. Hence the author has adapted a commercially available lumbar peritoneal shunt system to function as a lumbar intrathecal reservoir. The procedure is simple and can be performed expeditiously under local anaesthesia. To date, eight cases have received intrathecal chemotherapy by this means. PMID:3838918

    Few data are available to help predict which older cancer patient is at risk of developing chemotherapy-related toxicity. This study was a pilot for a project designing a predictive risk score. Chemotherapy patients aged 70 years and older were prospectively enrolled. Chemotherapies were adjusted for their published toxicity. 60 patients were enrolled, 59 were evaluable. Mean dose-intensity was 90.3%, range 33.3-129.0%. 47% of the patients experienced grade 4 haematological and/or grade 3-4 non-haematological toxicity. Published toxicity (MAX2), diastolic blood pressure, marrow invasion and lactate dehydrogenase (LDH) were all associated with toxicity (P<0.1); Body Mass Index, previous chemotherapy, red blood cells, platelets, polymedication with dose-intensity; and polymedication with FACT-G change. After adjustment for the published toxicity, the variables retained their significance, except for LDH and polymedication (for dose-intensity). Although the size of this pilot study imposes a cautious interpretation, patient-related and chemotherapy-related variables correlated independently with toxicity. Designing a composite predictive score to use in assessing the toxicity of multiple chemotherapy regimens therefore appears to be a valid undertaking. PMID:12110492

    Purpose The value of adding induction chemotherapy to chemoradiotherapy in locoregionally advanced nasopharyngeal carcinoma (LA-NPC) remains controversial, yet high-risk patients with LA-NPC have poor outcomes after chemoradiotherapy. We aimed to assess the survival benefits of induction chemotherapy in stage IVa-b NPC. Patients and Methods A total of 602 patients with stage IVa-b NPC treated with intensity-modulated radiation therapy (IMRT) and concurrent chemotherapy with or without induction chemotherapy were retrospectively analyzed. Overall survival (OS), locoregional relapse-free survival (LRFS), distant metastasis-free survival (DMFS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method, log-rank test and Cox regression analysis. Results In univariate analysis, 5-year OS was 83.2% for induction chemotherapy plus concurrent chemotherapy and 74.8% for concurrent chemotherapy alone, corresponding to an absolute risk reduction of 8.4% (P = 0.022). Compared to concurrent chemotherapy alone, addition of induction chemotherapy improved 5-year DMFS (83.2% vs. 74.4%, P = 0.018) but not 5-year LRFS (83.7% vs. 83.0%, P = 0.848) or PFS (71.9% vs. 66.0%, P = 0.12). Age, T category, N category, chemotherapy strategy and clinical stage were associated with 5-year OS (P = 0.017, P = 0.031, P = 0.007, P = 0.022, P = 0.001, respectively). In multivariate analysis, induction chemotherapy plus concurrent chemotherapy was an independent favorable prognostic factor for OS (HR, 0.62; 95% CI, 0.43–0.90, P = 0.012) and DMFS (HR, 0.57; 95% CI, 0.38–0.83, P = 0.004). In subgroup analysis, induction chemotherapy significantly improved 5-year DMFS in stage IVa (86.8% vs. 77.3%, P = 0.008), but provided no significant benefit in stage IVb. Conclusions In patients with stage IVa-b NPC treated with IMRT, addition of induction chemotherapy to concurrent chemotherapy significantly improved 5-year OS and 5-year DMFS. This study provides a basis for selection of

    Introduction There is no well-defined follow-up scheme available to reliably detect persistent or recurrent vesicoureteric reflux (VUR) after endoscopic therapy (ET), but also to reduce postoperative invasive diagnostics in these children. Our aim was the evaluation of possible predictors of persistence and recurrence of VUR, in order to elaborate and test a risk-adapted follow-up regimen. Material and methods 92 patients (85/92%f, 7/8%m, age 2.99y) underwent direct isotope cystography (DIC) three months after ET. Persistent or recurrent VUR, scarring on dimercaptosuccinic acid (DMSA) scans and further fUTIs after therapy (follow-up 24.6 m) were documented and analysed. Results VUR persistence 3 months after ET was found in 11 (11.9%) patients; recurrent VUR in 4 (4.3%) patients. Scarring on preoperative DMSA and dilating VUR (°III and °IV) were significantly associated with recurrent VUR. If only children with preoperative positive DMSA scan or dilating VUR would have undergone DIC, only 58/92 DICs (64%) would have been necessary. Only 45.5% of otherwise detected VURs would have been identified using this risk-adapted strategy. Conclusions Limiting invasive follow-up diagnostics (VCUG) and, therewith, the radiation burden in a predefined group of patients at risk for persistence or recurrence of VUR is not recommended, due to the significant chance of missing persistent or new onset contralateral VUR. Therefore, we recommend a routine follow-up VCUG after ET. Further prospective scientific efforts to evaluate new, alternative factors influencing persistence and recurrence of VUR, in order to establish an effective follow-up strategy, are warranted.

    Nausea and vomiting are two of the most troubling side effects patients experience during chemotherapy. While newly available treatments have improved our ability to manage nausea and vomiting, anticipatory and delayed nausea and vomiting are still a major problem for patients receiving chemotherapy. Many cancer patients will delay or refuse future chemotherapy treatments and contemplate stopping chemotherapy altogether because of their fear of experiencing further nausea and vomiting. The purpose of this article is to provide an overview of the patho-psychophysiology of chemotherapy-induced nausea and vomiting and the recommended guidelines for treatment. PMID:24466408

    Background Tumor resistance to chemotherapy may be present at the beginning of treatment, develop during treatment, or become apparent on re-treatment of the patient. The mechanisms involved are usually inferred from experiments with cell lines, as studies in tumor-derived cells are difficult. Studies of human tumors show that cells adapt to chemotherapy, but it has been largely assumed that clonal selection leads to the resistance of recurrent tumors. Methods Cells derived from 47 tumors of breast, ovarian, esophageal, and colorectal origin and 16 paired esophageal biopsies were exposed to anticancer agents (cisplatin; 5-fluorouracil; epirubicin; doxorubicin; paclitaxel; irinotecan and topotecan) in short-term cell culture (6 days). Real-time quantitative PCR was used to measure up- or down-regulation of 16 different resistance/target genes, and when tissue was available, immunohistochemistry was used to assess the protein levels. Results In 8/16 paired esophageal biopsies, there was an increase in the expression of multi-drug resistance gene 1 (MDR1) following epirubicin + cisplatin + 5-fluorouracil (ECF) chemotherapy and this was accompanied by increased expression of the MDR-1 encoded protein, P-gp. Following exposure to doxorubicin in vitro, 13/14 breast carcinomas and 9/12 ovarian carcinomas showed >2-fold down-regulation of topoisomerase IIα (TOPOIIα). Exposure to topotecan in vitro, resulted in >4-fold down-regulation of TOPOIIα in 6/7 colorectal tumors and 8/10 ovarian tumors. Conclusion This study suggests that up-regulation of resistance genes or down-regulation in target genes may occur rapidly in human solid tumors, within days of the start of treatment, and that similar changes are present in pre- and post-chemotherapy biopsy material. The molecular processes used by each tumor appear to be linked to the drug used, but there is also heterogeneity between individual tumors, even those with the same histological type, in the pattern and magnitude of

    Under a warming climate, frequent drought and water scarcity in northern China have severely disrupted agricultural production and posed a substantial threat to farmers' livelihoods. Based on first-hand data collected through in-depth interviews with local managers and farmer households, this study evaluated the effectiveness of rural land use management in mitigating drought risk, ensuring food security and improving farmers' livelihoods. Our findings indicate that a) reforestation on low-yield cropland not only can improve the eco-environment but can also prominently mitigate the production risk to local farmers; b) replacing the traditional border irrigation with sprinkler irrigation has substantially curbed agricultural water usage and increased the per unit of output; and c) in recent years, instead of planting water-intensive grain crops, local farmers cultivated more forage crops to raise animals, which greatly diversified their income sources and reduced the drought risk of agricultural production. By performing an empirical case study in drought-prone Inner Mongolia, this study provides decision-makers with insights into how to strategically adapt to drought risk and reduce rural poverty within the broader context of climate change.

    2002-01-01

    Small cell lung cancer (SCLC) is highly sensitive both to radiotherapy and chemotherapy. Given its high chemo sensitivity, even two decades ago, SCLC was one of the first malignancies deemed suitable for maximising the dose and dose intensity with the support of autologous bone marrow (ABMT). On the whole, results were disappointing and the procedure was practically abandoned. Nowadays some interest is again emerging due to improvements in supportive care, such as the availability of hematopoietic growth factors and the peripheral blood progenitor cells (PBPC). Data of 505 patients included in 26 studies were reviewed. About two thirds of these patients had LD (limited disease). Late intensification protocols were used in 311 patients who, however, represented only the 30% of the population initially given conventional chemotherapy. Of the patients not achieving complete remission (CR) after induction, high-dose induced a CR in 39% of the cases. The use of early intensification was reported in 8 studies including 194 patients. The CR rate was 51.5%. Overall, the probability of achieving the CR was 2-3 times higher in LD than in ED (extensive disease). Relapses occurred at the site of the primary in more than half of the cases, showing that the course of the disease was not modified by the use of high-dose chemotherapy. Toxic deaths occurred in 7% of the treated patients, without difference in the two treatment methods. Though the schedules were too variable to draw firm conclusions, the ICE (ifosfamide, carboplatin, etoposide) and the CBP (cyclophosphamide, cisplatin, carmustine) regimens apparently provided better results, with a 2-year survival rate of 30-50% in the LD subset. An european multicenter randomized trial is ongoing. At the present time high-dose chemotherapy is still to be considered experimental treatment, since major problems such as the selection of the patients, doses and timing of chemotherapy and radiotherapy remain unsolved.

    ABSTRACT Objective: To assess adherence of the prescribing physicians in a private cancer care center to the American Society of Clinical Oncology guideline for antiemetic prophylaxis, in the first cycle of antineoplastic chemotherapy. Methods: A total of 139 chemotherapy regimens, of 105 patients, were evaluated retrospectively from 2011 to 2013. Results: We observed 78% of non-adherence to the guideline rate. The main disagreements with the directive were the prescription of higher doses of dexamethasone and excessive use of 5-HT3 antagonist for low risk emetogenic chemotherapy regimens. On univariate analysis, hematological malignancies (p=0.005), the use of two or more chemotherapy (p=0.05) and high emetogenic risk regimes (p=0.012) were factors statistically associated with greater adherence to guidelines. Treatment based on paclitaxel was the only significant risk factor for non-adherence (p=0.02). By multivariate analysis, the chemotherapy of high emetogenic risk most correlated with adherence to guideline (p=0.05). Conclusion: We concluded that the adherence to guidelines is greater if the chemotherapy regime has high emetogenic risk. Educational efforts should focus more intensely on the management of chemotherapy regimens with low and moderate emetogenic potential. Perhaps the development of a computer generated reminder may improve the adherence to guidelines. PMID:26154543

    Background To evaluate outcome in patients with glottic cancer treated with intensity-modulated radiotherapy (IMRT) and to show effectiveness of partial laryngeal- and/or carotid artery sparing in low to intermediate risk tumors. Study design Retrospective analysis. Material and methods From 01/2004 to 03/2013 77 consecutive patients presenting with glottic cancer were treated in our department with IMRT as definitive treatment. T-stages distributed as follows: T1: n = 17, T2: n = 24, T3: n = 15, T4: n = 13 and recurrences: 8 patients. Concomitant systemic therapy was applied in 39 patients consisting of either cisplatin or cetuximab. Results Mean/median follow-up (FU) time was 32.2/28 months (range: 4–98.7). Three year local control (LC), ultimate LRC and laryngectomy free survival rate was 77%, 92% and 80%, respectively. Three year overall survival of the entire cohort was 81%. Three year local control for T1/T2, T3/T4, and recurred tumors was 95%, 65%, and 38%, respectively. Three year overall survival was 86% for T1-4 stages, 55% for recurred disease, respectively. Partial laryngeal/carotid artery sparing was performed in all T1 patients (n = 17) and 17/22 T2N0 patients. Rate of late sequels was low. Conclusion IMRT for glottic cancer shows high control rates. In low to intermediate risk tumors an individualized treatment volume with partial larynx +/- carotid artery sparing is effective and holds the potential to reduce long term toxicity. The therapeutic outcome was not compromised. PMID:24923417

    Cannabinoids (the active constituents of Cannabis sativa) and their derivatives have got intense attention during recent years because of their extensive pharmacological properties. Cannabinoids first developed as successful agents for alleviating chemotherapy associated nausea and vomiting. Recent investigations revealed that cannabinoids have a wide range of therapeutic effects such as appetite stimulation, inhibition of nausea and emesis, suppression of chemotherapy or radiotherapy-associated bone loss, chemotherapy-induced nephrotoxicity and cardiotoxicity, pain relief, mood amelioration, and last but not the least relief from insomnia. In this exploratory review, we scrutinize the potential of cannabinoids to counteract chemotherapy-induced side effects. Moreover, some novel and yet important pharmacological aspects of cannabinoids such as antitumoral effects will be discussed. PMID:25504799

    We investigated the benefit of adding all-trans retinoic acid (ATRA) to chemotherapy for younger patients with nonacute promyelocytic acute myeloid leukemia and high-risk myelodysplastic syndrome, and considered interactions between treatment and molecular markers. Overall, 1075 patients less than 60 years of age were randomized to receive or not receive ATRA in addition to daunorubicin/Ara-C/thioguanine chemotherapy with Ara-C at standard or double standard dose. There were data on FLT3 internal tandem duplications and NPM1 mutations (n = 592), CEBPA mutations (n = 423), and MN1 expression (n = 195). The complete remission rate was 68% with complete remission with incomplete count recovery in an additional 16%; 8-year overall survival was 32%. There was no significant treatment effect for any outcome, with no significant interactions between treatment and demographics, or cytarabine randomization. Importantly, there were no interactions by FLT3/internal tandem duplications, NPM1, or CEBPA mutation. There was a suggestion that ATRA reduced relapse in patients with lower MN1 levels, but no significant effect on overall survival. Results were consistent when restricted to patients with normal karyotype. ATRA has no overall effect on treatment outcomes in this group of patients. The study did not identify any subgroup of patients likely to derive a significant survival benefit from the addition of ATRA to chemotherapy. PMID:19965647

    Purpose: To evaluate the tolerability and toxicity of administering vaginal brachytherapy (VB) concurrently during chemotherapy compared with the sequential approach for patients with endometrial cancer. Methods and Materials: A retrospective analysis of 372 surgically staged patients with endometrial cancer American Joint Committee on Cancer 2009 stages I to IV treated with adjuvant postoperative radiation therapy (RT) at our institution from 2001 to 2012 was conducted. All patients received VB + external beam RT (EBRT) + 6 cycles of adjuvant carboplatin- and paclitaxel-based chemotherapy. The VB mean dose was 15.08 Gy (range, 15-20 Gy), with 3 to 4 weekly applications, and the EBRT mean dose was 45 Gy delivered with 3-dimensional or intensity modulated RT techniques. Hematologic, gastrointestinal (GI), and genitourinary (GU) toxicities were assessed by Common Toxicity Criteria (CTC) and compared between sequential and concurrent chemotherapy and VB schedules. Results: Among patients who received RT and adjuvant chemotherapy, 180 of 372 patients (48%) received RT sandwiched between cycles 3 and 4 of chemotherapy. A separate group of 192 patients (52%) were treated with VB during the first 3 cycles of chemotherapy, with a weekly application on nonchemotherapy days, and received the EBRT portion in a sandwiched fashion. Patients treated with VB during chemotherapy had a decreased overall treatment time by 4 weeks (P<.001; 95% confidence interval: 3.99-4.02) and sustained no difference in CTC-graded acute hematologic, GI, or GU toxicities in comparison with the patients treated with VB and chemotherapy in a sequential manner (P>.05). CTC grade 3 or 4 hematologic, GI, and GU toxicities were zero. Conclusions: VB during chemotherapy is well tolerated, decreases overall treatment time, and does not render more toxicity than the sequential regimen.

    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

    Waldenström macroglobulinemia is a B-cell malignancy with lymphoplasmacytic infiltration in the bone marrow or lymphatic tissue and a monoclonal immunoglobulin M protein (IgM) in the serum. It is incurable with current therapy, and the decision to treat patients as well as the choice of treatment can be complex. Using a risk-adapted approach, we provide recommendations on timing and choice of therapy. Patients with smoldering or asymptomatic Waldenström macroglobulinemia and preserved hematologic function should be observed without therapy. Symptomatic patients with modest hematologic compromise, IgM-related neuropathy that requires therapy, or hemolytic anemia unresponsive to corticosteroids should receive standard doses of rituximab alone without maintenance therapy. Patients who have severe constitutional symptoms, profound hematologic compromise, symptomatic bulky disease, or hyperviscosity should be treated with the DRC (dexamethasone, rituximab, cyclophosphamide) regimen. Any patient with symptoms of hyperviscosity should first be treated with plasmapheresis. For patients who experience relapse after a response to initial therapy of more than 2 years' duration, the original therapy should be repeated. For patients who had an inadequate response to initial therapy or a response of less than 2 years' duration, an alternative agent or combination should be used. Autologous stem cell transplant should be considered in all eligible patients with relapsed disease. PMID:20702770

  10. Chemotherapy and Dietary Phytochemical Agents

    PubMed Central

    Sak, Katrin

    2012-01-01

    Chemotherapy has been used for cancer treatment already for almost 70 years by targeting the proliferation potential and metastasising ability of tumour cells. Despite the progress made in the development of potent chemotherapy drugs, their toxicity to normal tissues and adverse side effects in multiple organ systems as well as drug resistance have remained the major obstacles for the successful clinical use. Cytotoxic agents decrease considerably the quality of life of cancer patients manifesting as acute complaints and impacting the life of survivors also for years after the treatment. Toxicity often limits the usefulness of anticancer agents being also the reason why many patients discontinue the treatment. The nutritional approach may be the means of helping to raise cancer therapy to a new level of success as supplementing or supporting the body with natural phytochemicals cannot only reduce adverse side effects but improve also the effectiveness of chemotherapeutics. Various plant-derived compounds improve the efficiency of cytotoxic agents, decrease their resistance, lower and alleviate toxic side effects, reduce the risk of tumour lysis syndrome, and detoxify the body of chemotherapeutics. The personalised approach using various phytochemicals provides thus a new dimension to the standard cancer therapy for improving its outcome in a complex and complementary way. PMID:23320169

    Development of new anticancer drugs has resulted in improved mortality rates and 5-year survival rates in patients with cancer. However, many of the modern chemotherapies are associated with cardiovascular toxicities that increase cardiovascular risk in cancer patients, including hypertension, thrombosis, heart failure, cardiomyopathy, and arrhythmias. These limitations restrict treatment options and might negatively affect the management of cancer. The cardiotoxic effects of older chemotherapeutic drugs such as alkylating agents, antimetabolites, and anticancer antibiotics have been known for a while. The newer agents, such as the antiangiogenic drugs that inhibit vascular endothelial growth factor signalling are also associated with cardiovascular pathology, especially hypertension, thromboembolism, myocardial infarction, and proteinuria. Exact mechanisms by which vascular endothelial growth factor inhibitors cause these complications are unclear but impaired endothelial function, vascular and renal damage, oxidative stress, and thrombosis might be important. With increasing use of modern chemotherapies and prolonged survival of cancer patients, the incidence of cardiovascular disease in this patient population will continue to increase. Accordingly, careful assessment and management of cardiovascular risk factors in cancer patients by oncologists and cardiologists working together is essential for optimal care so that prolonged cancer survival is not at the expense of increased cardiovascular events.

    The annual costs of chemotherapeutic agents from 1975 to 1980 were determined, and the impact on a hospital's budget of new chemotherapeutic agents marketed during this period was evaluated. Pharmacy purchasing records for the antineoplastics were reviewed retrospectively to determine fiscal year (FY) costs. Statistics from the Consumer Price Index report and hospital patient load were used to project an adjusted annual cost for cancer chemotherapy. The annual expenditures for seven agents marketed in the past five years were expressed as a percentage of the pharmacy's budget. In addition, the oncology clinic records for the past four years were reviewed to assess trends in the number of visits and quantity of drugs prescribed. Analysis indicated that the costs of antineoplastic drugs have risen from $10,156 for FY 1973-1974 to $296,914 for FY 1979-1980. Antineoplastic drug costs have risen from 5.74 to 16.74% of the total drug budget during the same period. Only a portion of the increase in costs could be attributed to increased patient load and inflation. The percentage of patients receiving chemotherapy has reached a plateau, and the quantity of agents being prescribed was not found to be increasing. It was concluded that the rise in cost tends to follow the recent commercial availability of several new antineoplastics, especially doxorubicin. Cancer drug costs will continue to represent a large portion of the total hospital budget in the future and budgets must be planned accordingly. PMID:7270558

  13. Chemotherapy-induced peripheral neuropathy.

    2015-01-01

    Chemotherapy-induced peripheral neuropathy (CIPN) is common in patients receiving anticancer treatment and can affect survivability and long-term quality of life of the patient following treatment. The symptoms of CIPN primarily include abnormal sensory discrimination of touch, vibration, thermal information, and pain. There is currently a paucity of pharmacological agents to prevent or treat CIPN. The lack of efficacious therapeutics is due, at least in part, to an incomplete understanding of the mechanisms by which chemotherapies alter the sensitivity of sensory neurons. Although the clinical presentation of CIPN can be similar with the various classes of chemotherapeutic agents, there are subtle differences, suggesting that each class of drugs might induce neuropathy via different mechanisms. Multiple mechanisms have been proposed to underlie the development and maintenance of neuropathy; however, most pharmacological agents generated from preclinical experiments have failed to alleviate the symptoms of CIPN in the clinic. Further research is necessary to identify the specific mechanisms by which each class of chemotherapeutics induces neuropathy. PMID:25744683

    Background This study aimed to explore the subjective experience of nausea and vomiting during chemotherapy treatment among breast cancer patients and the impacts on their daily lives. Methods A qualitative descriptive study was conducted in breast cancer patients who received chemotherapy and had experienced nausea and/or vomiting. Semi-structured interviews were conducted and analyzed using content analysis based on Giorgi’s method. Results Of 15 patients who participated, 13 were included in the final analysis (median age =46 years, interquartile range [IQR] =6.0; all were Malays). Vomiting was readily expressed as the “act of throwing up”, but nausea was a symptom that was difficult to describe. Further exploration found great individual variation in patterns, intensity, and impact of these chemotherapy-induced nausea and vomiting (CINV) symptoms. While not all patients expressed CINV as bothersome, most patients described the symptom as quite distressing. CINV was reported to affect many aspects of patients’ lives particularly eating, physical, emotional, and social functioning, but the degree of impacts was unique to each patient. One of the important themes that emerged was the increase in worship practices and “faith in God” among Malay Muslim patients when dealing with these adverse effects. Conclusion CINV continues to be a problem that adversely affects the daily lives of patients, hence requiring better understandings from the health care professionals on patients’ needs and concerns when experiencing this symptom.

    2015-01-01

    We report the case of a previously well 58-year-old man who presented with headache and confusion 4 days postadministration of intrathecal methotrexate. He was undergoing intensive chemotherapy (CODOX-M/IVAC, cyclophosphamide, doxorubicin, vincristine, methotrexate, etoposide, ifosfamide, cytarabine) for the treatment of leukaemic phase CD20 negative diffuse large B-cell lymphoma. A CT of the head demonstrated the presence of bilateral subdural hygromas complicated by haemorrhage resulting from coexisting chemotherapy induced thrombocytopenia. Surgical drainage of the hygroma was undertaken but the patient died of overwhelming sepsis. In patients with high-risk lymphoma, directed central nervous system (CNS) therapy is administered either systemically or intrathecally. It is thought that subdural hygromas result from cerebrospinal fluid (CSF) accumulation in the inner dural layers of the cerebral convexities from CSF leak and reduction in CSF pressure post-lumbar puncture. We describe a rare but potentially fatal complication of intrathecal chemotherapy that haemato-oncologists need to be mindful of. PMID:26002663

    Cardiac involvement as an initial presentation of malignant lymphoma is a rare occurrence. We describe the case of a 26 year old man who had initially been diagnosed with myocardial infiltration on an echocardiogram, presenting with a testicular mass and unilateral peripheral facial paralysis. On admission, electrocardiograms (ECG) revealed negative T-waves in all leads and ST-segment elevation in the inferior leads. On two-dimensional echocardiography, there was infiltration of the pericardium with mild effusion, infiltrative thickening of the aortic walls, both atria and the interatrial septum and a mildly depressed systolic function of both ventricles. An axillary biopsy was performed and reported as a T-cell lymphoblastic lymphoma (T-LBL). Following the diagnosis and staging, chemotherapy was started. Twenty-two days after finishing the first cycle of chemotherapy, the ECG showed regression of T-wave changes in all leads and normalization of the ST-segment elevation in the inferior leads. A follow-up Two-dimensional echocardiography confirmed regression of the myocardial infiltration. This case report illustrates a lymphoma presenting with testicular mass, unilateral peripheral facial paralysis and myocardial involvement, and demonstrates that regression of infiltration can be achieved by intensive chemotherapy treatment. To our knowledge, there are no reported cases of T-LBL presenting as a testicular mass and unilateral peripheral facial paralysis, with complete regression of myocardial involvement. PMID:24109501

    Peritoneal spread of tumors is a major problem in cancer management. Patients develop a marked deterioration in quality of life and shortened survival. This is in part due to bowel obstructions, marked ascites, and overall increase debilitation. Standard medical management has shown to be inadequate for the treatment of these problems. Surgery can palliate symptoms, however, it is unable to be complete at the microscopic level by a significant spillage of tumor cells throughout the abdomen. Chemotherapy can have some improvement in symptoms however it is short lived due to poor penetration into the peritoneal cavity. The role of intraperitoneal chemotherapy is to maximize tumor penetration and optimize cell death while minimizing systemic toxicity. Hyperthermic intraperitoneal chemotherapy (HIPEC) and early post-operative intraperitoneal chemotherapy (EPIC) are two treatment methods that serve this role and have been shown to improve survival. This review will discuss different chemotherapies used for both of these treatment options. PMID:26941983

    Objectives To review the evidence for the use of various biomarkers in the detection of chemotherapy associated cardiac damage. Design and methods Pubmed.gov was queried using the search words chemotherapy and cardiac biomarkers with the filters of past 10 years, humans, and English language. An emphasis was placed on obtaining primary research articles looking at the utility of biomarkers for the detection of chemotherapy-mediated cardiac injury. Results Biomarkers may help identify patients undergoing treatment who are at high risk for cardiotoxicity and may assist in identification of a low risk cohort that does not necessitate continued intensive screening. cTn assays are the best studied biomarkers in this context and may represent a promising and potentially valuable modality for detecting cardiac toxicity in patients undergoing chemotherapy. Monitoring cTnI levels may provide information regarding the development of cardiac toxicity before left ventricular dysfunction becomes apparent on echocardiography or via clinical symptoms. A host of other biomarkers have been evaluated for their utility in the field of chemotherapy related cardiac toxicity with intermittent success; further trials are necessary to determine what role they may end up playing for prediction and prognostication in this setting. Conclusions Biomarkers represent an exciting potential complement or replacement for echocardiographic monitoring of chemotherapy related cardiac toxicity which may allow for earlier realization of the degree of cardiac damage occurring during treatment, creating the opportunity for more timely modulation of therapy.

    The clinical outcome and efficacy of postoperative chemotherapy in patients with Stage Ⅳ colorectal cancer with perforation were investigated. We compared the clinical outcomes between 11 patients with Stage Ⅳ colorectal cancer (perforation group), who underwent emergency surgery for colonic perforation between September 2005 and March 2012, and 22 matched patients (matching group) who underwent elective colorectal surgery during the same period. The colostomy rate in the perforation group was significantly higher than that of the matching group: patients with perforation received stoma construction surgery more frequently (p<0.01). Seven patients (64%) in the perforation group received postoperative chemotherapy, while 20 patients (91%) in the matching group received chemotherapy (p=0.15). Oxaliplatin-based chemotherapy was administered to all patients in both groups. There was no difference in the median relative dose intensity of oxaliplatin between these groups (p=0.37). No significant difference was observed between the cumulative 3-year overall survival rate in the perforation group and that of the matching group (35% and 54%, respectively; p=0.35). Moreover, the 3-year overall survival rates of patients who received oxaliplatin-based chemotherapy were 51%in the perforation group and 57% in the matching group (p=0.74). Our results suggest that postoperative oxaliplatin-based chemotherapy may improve the prognosis of patients with Stage Ⅳ colorectal cancer with perforation. PMID:26805324

    Although cytoreductive surgery (CRS) and hyperthermic perioperative chemotherapy (HIPEC) have not been shown to be effective by themselves, as a combined treatment they are now standard of care for peritoneal metastases from appendiceal cancer and from colorectal cancer as well as peritoneal mesothelioma. The timing of the HIPEC in relation to the CRS is crucial in that the HIPEC is to destroy minimal residual disease that remains following the CRS and prevent microscopic tumor emboli within the abdomen and pelvis from implanting within the resection site, within fibrinous clot, or within blood clot. Proper selection of chemotherapy agents is crucial to the long-term benefit of CRS and HIPEC. One must consider the response expected with the cancer chemotherapy agent, its area under the curve (AUC) ratio indicating the amount of dose intensity within the peritoneal space, and the drug retention within the peritoneal space for a prolonged exposure. Hyperthermia will augment the cytotoxicity of the cancer chemotherapy agents and improve drug penetration. Irrigation techniques should not be overlooked as an important means of reducing the cancer cell burden within the abdomen and pelvis. Multiple technologies for HIPEC exist and these have advantages and disadvantages. The techniques vary from a totally open technique with a vapor barrier over the open abdominal space to a totally closed technique whereby the HIPEC is administered at the completion of the surgical procedure. The open techniques depend on a table-mounted retractor for suspension of the skin edges allowing a reservoir to occur within the abdomen and pelvis. There are nearly a dozen commercially available hyperthermia pumps, all of which seem to perform adequately for HIPEC although there is a variable degree of convenience and documentation of the HIPEC procedure. As the management of peritoneal metastases has progressed over three decades, early cases are now seen in which a laparoscopic CRS and HIPEC

    Objective The objective of this pilot study was to describe the effects of a 16-week home-based rehabilitative exercise program on cancer-related fatigue (CRF), other symptoms, functional status, and quality of life (QOL) for patients with non-small cell lung cancer (NSCLC) after thoracotomy starting within days after hospital discharge and continuing through the initiation and completion of chemotherapy. Materials and methods Five patients with NSCLC completed the Brief Fatigue Inventory (measuring CRF severity) and the MD Anderson Symptom Inventory (measuring symptom severity) before and after thoractomy, and at the end of each week of the 16-week exercise program. Additionally, the Medical Outcomes Study Short Form-36 (measuring physical and mental functional status) and the Quality of Life Index (measuring QOL) were completed before and after thoracotomy, after weeks 3, 6, 12, and 16 (the end of the exercise program). Further, the 6-minute walk test (measuring functional capacity) was administered before thoracotomy, prior to the initiation of chemotherapy and/or radiation therapy, and at the end of the 16-week exercise program, after completion of chemotherapy. Results Participants had a mean age of 63 years and a mean of five comorbid conditions; the exercise program was initiated within 4 days after hospital discharge. Participants’ CRF severity scores were reduced to mild levels, while the mean number of symptoms decreased from 9 postthoracotomy to 6 after the exercise program, with mean levels of severity and interference decreasing to below prethoracotomy levels. Likewise, participants’ functional status and QOL after completing the exercise program improved to near or above prethoracotomy levels. Conclusion The home-based, light-intensity exercise program for NSCLC patients receiving and completing adjuvant chemotherapy postthoracotomy showed promising trends in improving CRF severity, other symptom severity, functional status, and QOL.

    Systemic chemotherapy is integral to the management of muscle-invasive and metastatic bladder cancer (BCa). Neoadjuvant chemotherapy has been increasingly utilized for muscle-invasive BCa over the past several years, and several options for cisplatin-based regimens have emerged. Adjuvant chemotherapy may be considered for select patients who did not receive neoadjuvant therapy. Systemic chemotherapy added to radiotherapy is a critical component of a bladder-preserving approach and superior to radiotherapy alone. Cisplatin-based chemotherapy has been the mainstay for metastatic BCa for more than three decades. Novel targeted agents are in development fueled by the recent molecular characterization of BCa. Recent trials of immunotherapy have demonstrated the possibility of a less toxic and potentially more effective treatment for metastatic disease. It is an extremely exciting time for BCa research, and much needed improvements in systemic treatment are most certainly on the horizon. PMID:26984414

    The best treatment of follicular lymphoma remains to be determined because the long natural history of follicular lymphoma requires mature data for accurate analysis. Although the goal of primary treatment remains durable remission, the sequential application of effective treatments may also result in a prolongation of median survival time. The use of interferon (IFN) with doxorubicin-based chemotherapy has demonstrated an increase of event-free survival but not in overall survival; however, its acute and late cardiac toxicity limits its use. For this reason, we began a controlled clinical trial to assess the efficacy and toxicity of chemotherapy: COPP (cyclophosphamide, vincristine, prednisone, and procarbazine) + IFN alternating every month for six cycles compared to six cycles of chemotherapy. In an intent-to treat analysis, 55 patients were enrolled (median age 61 years). Most cases (91%) with advanced disease were randomly assigned to chemotherapy + IFN (28 cases) or chemotherapy (27 cases). Complete remission was observed in 16 patients: 59% (95% CI, 53-70%) in the chemotherapy arm compared to 20 patients 71% (95% CI, 58-79%) in the chemotherapy + IFN arm; total responses were 74% and 86%, respectively. At a median follow-up of 60 months, event-free survival was 100% for patients treated with chemotherapy + IFN, which was statistically different from patients treated with chemotherapy 70%. At 7 years, median survival has not yet been reached; 72% of patients chemotherapy + IFN remain alive without disease (95% CI, 59-81%), which is not statistically different from 72% (95%CI, 50-73%) in the chemotherapy arm. Non-hematological toxicity was most frequent and severe in the chemotherapy arm; hematological toxicity was similar in both groups. Thus, it appears that chemotherapy + IFN, as described herein, improves event-free survival but the overall survival rates remain unchanged. The use of COPP appears to be better that anthracycline-based chemotherapy because

    The potentiation of chemotherapeutic agents by radiation sensitizers has been extensively studied for several years. There is little doubt that the effectiveness of certain anti-cancer drugs, primarily alkylating agents, can readily be enhanced both in vitro and in vivo through the addition of a sensitizer. While enhanced effects have been observed in certain critical normal tissues, in general most animal model studies have demonstrated a therapeutic gain at large sensitizer doses. This approach to combination therapies therefore appears promising. Yet many questions concerning the interaction between chemotherapeutic agents and radiosensitizers, particularly in the aspects of modification of chemotherapy by nitroimidazoles are reviewed and discussed. These address the importance in chemopotentiation of (i) hypoxia, (ii) alterations in DNA damage and/or repair, (iii) depletion of intracellular sulfhydryls and (iv) modification of drug pharmacokinetics.

    Trace elements might be associated with the development of hepatocellular carcinoma (HCC) and the efficacy of chemotherapy against HCC. Therefore, this study aimed to explore the association between trace elements and efficacy of chemotherapy in patients with HCC. Cancer, cancer-adjacent, and cancer-free tissues were collected intraoperatively from 55 patients with HCC between January 2001 and April 2004 at the Affiliated Tumor Hospital of Guangxi Medical University in Guangxi (China), a high HCC incidence area in the world. Trace element levels were analyzed by atomic absorption spectrophotometry. In vitro sensitivity of cancer cells to five chemotherapeutic drugs (5-fluorouracil, doxorubicin, cisplatin, carboplatin, and mitomycin) was tested using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay in cancer cells from 32 patients. Zinc, copper, manganese, and selenium levels had the same gradient distribution in different liver tissues: cancer < cancer-adjacent < cancer-free tissues. Copper levels of cancer tissues were negatively correlated with body weight (r = -0.278, P = 0.027), while manganese and selenium levels were negatively correlated with age (r = -0.297, P = 0.015; r = -0.285, P = 0.018, respectively). Simple correlation analyses revealed that the carboplatin sensitivity was negatively correlated with selenium levels of cancer tissues, while doxorubicin sensitivity was negatively correlated with manganese levels (r = -0.497, P = 0.004). Partial correlation analyses showed that doxorubicin sensitivity only was negatively correlated with manganese levels (r = -0.450, P = 0.014). These results suggest that the selenium and manganese content in primary HCC tissues could influence the response of the HCC cells to carboplatin and doxorubicin. These preliminary results provide a basis for future studies. PMID:26961293

    Background Fractures of the long bones and femur fractures in particular are common in multiple trauma patients, but the optimal management of femur fractures in these patients is not yet resolved. Although there is a trend towards the concept of "Damage Control Orthopedics" (DCO) in the management of multiple trauma patients with long bone fractures as reflected by a significant increase in primary external fixation of femur fractures, current literature is insufficient. Thus, in the era of "evidence-based medicine", there is the need for a more specific, clarifying trial. Methods/Design The trial is designed as a randomized controlled open-label multicenter study. Multiple trauma patients with femur shaft fractures and a calculated probability of death between 20 and 60% will be randomized to either temporary fracture fixation with fixateur externe and defined secondary definitive treatment (DCO) or primary reamed nailing (early total care). The primary objective is to reduce the extent of organ failure as measured by the maximum sepsis-related organ failure assessment (SOFA) score. Discussion The Damage Control Study is the first to evaluate the risk adapted damage control orthopedic surgery concept of femur shaft fractures in multiple trauma patients in a randomized controlled design. The trial investigates the differences in clinical outcome of two currently accepted different ways of treating multiple trauma patients with femoral shaft fractures. This study will help to answer the question whether the "early total care" or the „damage control” concept is associated with better outcome.

    Background: There are no well-established normal tissue sparing dose–volume histogram (DVH) criteria that limit the risk of urinary toxicity from prostate radiation therapy (RT). The aim of this study was to determine which criteria predict late toxicity among various DVH parameters when contouring the entire solid bladder and its contents versus the bladder wall. The area under the histogram curve (AUHC) was also analyzed. Methods and Materials: From 1993 to 2000, 503 men with prostate cancer received 3-dimensional conformal RT (median follow-up time, 71 months). The whole bladder and the bladder wall were contoured in all patients. The primary endpoint was grade ≥2 genitourinary (GU) toxicity occurring ≥3 months after completion of RT. Cox regressions of time to grade ≥2 toxicity were estimated separately for the entire bladder and bladder wall. Concordance probability estimates (CPE) assessed model discriminative ability. Before training the models, an external random test group of 100 men was set aside for testing. Separate analyses were performed based on the mean age (≤ 68 vs >68 years). Results: Age, pretreatment urinary symptoms, mean dose (entire bladder and bladder wall), and AUHC (entire bladder and bladder wall) were significant (P<.05) in multivariable analysis. Overall, bladder wall CPE values were higher than solid bladder values. The AUHC for bladder wall provided the greatest discrimination for late bladder toxicity when compared with alternative DVH points, with CPE values of 0.68 for age ≤68 years and 0.81 for age >68 years. Conclusion: The AUHC method based on bladder wall volumes was superior for predicting late GU toxicity. Age >68 years was associated with late grade ≥2 GU toxicity, which suggests that risk-adapted dose constraints based on age should be explored.

Of these, 2 relapsed within 3 months after BMT (2 allogeneic BMT) and 6 (2 allogeneic and 4 autologous BMT) after more than 9 months after BMT. The 2 patients relapsing early showed no response to treatment and died. Five out of 6 patients relapsing late achieved complete remission (4 of them with intensive chemotherapy). Four patients are currently alive. Aggressive combination chemotherapy can produce long-term survival in selected patients relapsed after BMT. PMID:1519431

    The standard of care for advanced epithelial ovarian carcinoma has been primary surgery aspiring for optimal debulking followed by adjuvant chemotherapy. A significant survival advantage has been demonstrated in women having optimal debulking at primary surgery compared to women having less than optimal debulking at primary surgery. With the advent of efficient chemotherapy for ovarian carcinoma (combination of platinum and taxan), the administration of several courses of chemotherapy before surgery (neoadjuvant chemotherapy) has been established as a method for reducing the intra-abdominal tumor burden and, thereby, increasing the probability of optimal debulking at surgery which is usually performed in the interval between course no. 3 and no. 4 of chemotherapy (interval surgery).

    The standard of care for advanced epithelial ovarian carcinoma has been primary surgery aspiring for optimal debulking followed by adjuvant chemotherapy. A significant survival advantage has been demonstrated in women having optimal debulking at primary surgery compared to women having less than optimal debulking at primary surgery. With the advent of efficient chemotherapy for ovarian carcinoma (combination of platinum and taxan), the administration of several courses of chemotherapy before surgery (neoadjuvant chemotherapy) has been established as a method for reducing the intra-abdominal tumor burden and, thereby, increasing the probability of optimal debulking at surgery which is usually performed in the interval between course no. 3 and no. 4 of chemotherapy (interval surgery). Higher rates of optimal debulking, Lower rates of surgical complications, but no differences in survival, have been demonstrated in women having chemotherapy before surgery compared to women having surgery before chemotherapy. Obviously, the method of neoadjuvant chemotherapy is the treatment of choice for women in whom the clinical evaluation indicates that there is no high probability of optimal debulking at primary surgery. Nevertheless, there has been a debate on whether or not the method of neoadjuvant chemotherapy should also be applied for women in whom the clinical evaluation indicates that they are fit for optimal debulking at primary surgery. There is a need for more prospective studies to evaluate the role of neoadjuvant chemotherapy in the treatment of ovarian carcinoma. PMID:25507216

    Bevacizumab plus chemotherapy was approved by the US Food and Drug Administration (FDA) as a first-line treatment for advanced nonsquamous, non-small-cell lung cancer (NSCLC) in 2006. This study retrospectively compared the efficacy of bevacizumab plus chemotherapy with chemotherapy alone as the first-line and second-line treatment as well as the maintenance treatment for advanced NSCLC patients. A total of 1,352 patients were included and we analyzed the efficacy evaluation according to the criteria of the Response Evaluation Criteria In Solid Tumors (RECIST), survival, and adverse reactions. The data showed that for bevacizumab plus chemotherapy as the first-line treatment, the median progression-free survival (mPFS) and median overall survival (mOS) were 11.5 and 17.0 months, respectively, compared to 7.0 and 14 months, respectively, in patients who received chemotherapy alone (P<0.01). With bevacizumab plus chemotherapy as maintenance treatment, the mPFS and mOS were 6.0 and 17.4 months, respectively, compared to 3.0 and 15.0 months, respectively, with chemotherapy alone (P<0.01). With bevacizumab plus chemotherapy as the second-line treatment, the mPFS was 3.0 months compared to only 2.0 months with chemotherapy alone (P<0.01). The overall responses to the different regimens showed that the remission rate with bevacizumab plus chemotherapy was higher than that with chemotherapy alone (31.8% vs 25.5%, P<0.05), although there was no statistical difference in the disease control rate with either first- or second-line treatment. In conclusion, chemotherapy plus bevacizumab as the first-line and maintenance treatment, led to better curative rates and tolerable adverse reactions compared with chemotherapy alone in advanced NSCLC patients. Bevacizumab combined with cytotoxic drugs was suitable as the second-line treatment for such patients. PMID:27536131

  16. Myelosuppression grading of chemotherapies for hematologic malignancies to facilitate communication between medical and dental staff: lessons from two cases experienced odontogenic septicemia

    PubMed Central

    2013-01-01

    Background Odontogenic diseases can be a risk factor for life-threatening infection in patients with hematologic malignancies during chemotherapy that induces myelosuppression of variable severity. Previous studies noted the necessity of the elimination of all odontogenic foci before hematopoietic stem cell transplantation. To enable planning for the adequate dental intervention, the oral medicine team must understand the general status of patient and the intensity of the chemotherapy, which is sometimes difficult to be fully appreciated by dental staff. Therefore, a simplified grading would facilitate the sharing of information between hematologists, dentists and oral hygienists. This study aimed to introduce our myelosuppression grading of chemotherapies for hematologic malignancies and analyze the timing of occurrence of severe odontogenic infection. Methods 37 patients having received various chemotherapies for hematologic malignancies were enrolled. The chemotherapy regimens were classified into four grades based on the persistency of myelosuppression induced by chemotherapy. Mild myelosuppressive chemotherapies were classified as grade A, moderate ones as grade B, severe ones as grade C, and chemotherapies that caused severe myelosuppression and persistent immunodeficiency (known as conditioning regimens for transplant) as grade D. The timing of occurrence of severe odontogenic infection was retrospectively investigated. Results Two patients (5.4%) had severe odontogenic infections after grade B or C chemotherapy. One occurred after extraction of non-salvageable teeth; the other resulted from advanced periodontitis in a tooth that could not be extracted because of thrombocytopenia. Both were de novo hematologic malignancy patients. During grade D chemotherapy, no patients had severe odontogenic infections. Conclusions The simplified grading introduced in this study is considered a useful tool for understanding the myelosuppressive state caused by chemotherapy

    Purpose/Objectives To explore virtual reality (VR) as a distraction intervention to relieve symptom distress in adults receiving chemotherapy treatments for breast, colon, and lung cancer. Design Crossover design in which participants served as their own control. Setting Outpatient clinic at a comprehensive cancer center in the southeastern United States. Sample 123 adults receiving initial chemotherapy treatments. Methods Participants were randomly assigned to receive the VR distraction intervention during one chemotherapy treatment and then received no intervention (control) during an alternate matched chemotherapy treatment. The Adapted Symptom Distress Scale–2, Revised Piper Fatigue Scale, and State Anxiety Inventory were used to measure symptom distress. The Presence Questionnaire and an open-ended questionnaire were used to evaluate the subjects’ VR experience. The influence of type of cancer, age, and gender on symptom outcomes was explored. Mixed models were used to test for differences in levels of symptom distress. Main Research Variables Virtual reality and symptom distress. Findings Patients had an altered perception of time (p < 0.001) when using VR, which validates the distracting capacity of the intervention. Evaluation of the intervention indicated that patients believed the head-mounted device was easy to use, they experienced no cybersickness, and 82% would use VR again. However, analysis demonstrated no significant differences in symptom distress immediately or two days following chemotherapy treatments. Conclusions Patients stated that using VR made the treatment seem shorter and that chemotherapy treatments with VR were better than treatments without the distraction intervention. However, positive experiences did not result in a decrease in symptom distress. The findings support the idea that using VR can help to make chemotherapy treatments more tolerable, but clinicians should not assume that use of VR will improve chemotherapy

    The combination of complete cytoreductive surgery and perioperative intraperitoneal chemotherapy provides the only chance for long-term survival for selected patients diagnosed with a variety of peritoneal neoplasms, either primary or secondary to digestive or gynecologic malignancy. Hyperthermic intraperitoneal chemotherapy (HIPEC) delivered in the operating room once the cytoreductive surgical procedure is finalized, constitutes the most common form of administration of perioperative intraperitoneal chemotherapy. This may be complemented in some instances with early postoperative intraperitoneal chemotherapy (EPIC). HIPEC combines the pharmacokinetic advantage inherent to the intracavitary delivery of certain cytotoxic drugs, which results in regional dose intensification, with the direct cytotoxic effect of hyperthermia. Hyperthermia exhibits a selective cell-killing effect in malignant cells by itself, potentiates the cytotoxic effect of certain chemotherapy agents and enhances the tissue penetration of the administered drug. The chemotherapeutic agents employed in HIPEC need to have a cell cycle nonspecific mechanism of action and should ideally show a heat-synergistic cytotoxic effect. Delivery of HIPEC requires an apparatus that heats and circulates the chemotherapeutic solution so that a stable temperature is maintained in the peritoneal cavity during the procedure. An open abdomen (Coliseum) or closed abdomen technique may be used, with no significant differences in efficacy proven to date. Specific technical training and a solid knowledge of regional chemotherapy management are required. Concerns about safety of the procedure for operating room personnel are expected but are manageable if universal precautions and standard chemotherapy handling procedures are used. Different HIPEC drug regimens and dosages are currently in use. A tendency for concurrent intravenous chemotherapy administration (bidirectional chemotherapy, so-called “HIPEC plus”) has

    Recent advances in our understanding of the mechanisms underlying the impact of cytotoxic drugs on the ovary have opened up new directions for the protection of the ovary from chemotherapy-induced damage. These advances have spurred the investigation of pharmacological agents to prevent ovarian damage at the time of treatment. Prevention of ovarian damage and follicle loss would provide significant advantages over existing fertility preservation techniques. This manuscript reviews new methods for the prevention of chemotherapy-induced ovarian damage, including agents that act on the PI3K/PTEN/Akt follicle activation pathway, apoptotic pathways, the vascular system, and other potential methods of reducing chemotherapy-induced ovotoxicity.

    The combined modality treatment of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has gained worldwide acceptance for management of selected patients with peritoneal metastases from various cancers. Cytoreductive surgery is performed with the goal of removing all macroscopic disease and is coupled with perioperative chemotherapy (POC) in the form of HIPEC with or without EPIC (early postoperative intraperitoneal chemotherapy) to deal with the microscopic residual disease. These treatments entail the use of cytotoxic drugs in the operation theatre or in the intensive care unit where they are not commonly used and put the healthcare workers participating in the treatment at risk of exposure. CRS is performed with high voltage electrocautery generating a large amount of surgical smoke which is inhaled by the involved personnel and has potential health hazards. This article outlines the safety measures to be taken while performing CRS and POC. PMID:27065717

    Summary For over 40 years, natural products have served us well in combating cancer. The main sources of these successful compounds are microbes and plants from the terrestrial and marine environments. The microbes serve as a major source of natural products with anti‐tumour activity. A number of these products were first discovered as antibiotics. Another major contribution comes from plant alkaloids, taxoids and podophyllotoxins. A vast array of biological metabolites can be obtained from the marine world, which can be used for effective cancer treatment. The search for novel drugs is still a priority goal for cancer therapy, due to the rapid development of resistance to chemotherapeutic drugs. In addition, the high toxicity usually associated with some cancer chemotherapy drugs and their undesirable side‐effects increase the demand for novel anti‐tumour drugs active against untreatable tumours, with fewer side‐effects and/or with greater therapeutic efficiency. This review points out those technologies needed to produce the anti‐tumour compounds of the future. PMID:21375717

    For over 50 years, amphotericin B deoxycholate (AmBD) has been the 'gold standard' in antifungal chemotherapy, despite its frequent toxicities. However, improved treatment options for invasive fungal infections (IFIs) have been developed during the last 15 years. Newer antifungal agents, including less toxic lipid preparations of AmBD, triazoles and the echinocandins, have been added to our armamentarium against IFIs. Some of these newer drugs can now replace AmBD as primary therapy (e.g. caspofungin for candidiasis, voriconazole for aspergillosis), whilst others offer new therapeutic options for difficult-to-treat IFIs (e.g. posaconazole for zygomycosis, fusariosis and chromoblastomycosis). It is interesting that extended use of newer antifungals such as fluconazole, despite decreasing the mortality attributed to candidiasis, resulted in selection of species resistant to several antifungals (Candida krusei, Candida glabrata); whilst several publications suggest that prolonged use of voriconazole may expose severely immunocompromised patients to the risk of zygomycosis (breakthrough). On the other hand, the differences in the mode of action of newer antifungals such as echinocandins raise the question whether combination antifungal therapy is more effective than monotherapy. Finally, the availability of an oral formulation with excellent biosafety of several newer antifungals (e.g. posaconazole) makes them candidates for prophylactic or prolonged maintenance therapy.

    Present epidemic influenza is uncontrolled by immuno- or chemoprophylaxis. Mutants of varying antigenic composition arise with relatively high frequency in nature and are able to circumvent herd, or induced, immunity. Also, drug-resistant viruses can be selected in vitro and this resistance can be exchanged to other viruses by gene reassortment. Combined immuno- and chemoprophylaxis may provide a more effective approach to the ultimate control of the disease. Most antiviral compounds have been selected by random screening in the laboratory. Application of more specific enzyme assays such as the virion-associated RNA transcriptase assays may produce other compounds with a defined mode of action - semi-rational chemotherapy. RNA and polypeptide sequence studies are in progress elsewhere to define transcription and translation initiation sites or virus adsorption sites. Such knowledge could lead to a new generation of antiviral compounds. Specific delivery of virus inhibitory compounds is an interesting problem. Liposomes are lipid spheres, and these have been used for the delivery of antiviral compounds. Images Fig. 3a. Fig. 3b. Fig. 4 Fig. 5 PMID:461275

    Despite significant improvements in diagnostic methods and innovations in therapies for specific cancers, effective treatments for neoplastic diseases still represent major challenges. Nanotechnology as an emerging technology has been widely used in many fields and also provides a new opportunity for the targeted delivery of cancer drugs. Nanoscale delivery of chemotherapy drugs to the tumor site is highly desirable. Recent studies have shown that nanoscale drug delivery systems not only have the ability to destroy cancer cells but may also be carriers for chemotherapy drugs. Some studies have demonstrated that delivery of chemotherapy via nanoscale carriers has greater therapeutic benefit than either treatment modality alone. In this review, novel approaches to nanoscale delivery of chemotherapy are described and recent progress in this field is discussed. PMID:27235607

    Eight patients with nine histologically proven BCC or SCC involving the eyelids and periorbital tissues were treated with systemic and/or local (iontophoresis) chemotherapy using cisplatin and doxorubicin. All patients had either refused surgery, would have required extensive procedures, or had medical problems contraindicating surgery. Systemic chemotherapy induced a CR or PR in eight of nine lesions. No patient has required maintenance chemotherapy and no significant toxic side effects were encountered. The length of follow-up ranges from 2 to 50 months. Iontophoretic therapy with cisplatin was used to treat five small foci of new, recurrent or persistent tumor(s) in three of these patients, and resulted in a partial response in all five lesions. Systemic or local chemotherapy offers an alternative to current standard forms of treatment for BCC and SCC in selected cases.

    2015-01-01

    Introduction of cisplatin based chemotherapy has revolutionized the treatment of germ cell tumors. A common side effect of multiday cisplatin chemotherapy is severe nausea and vomiting. Considerable progress has been made in the control of these side effects since the introduction of cisplatin based chemotherapy in the 1970s. Germ cell tumor which is a model for a curable neoplasm has also turned into an excellent testing ground to develop effective strategies to prevent chemotherapy induced nausea and vomiting (CINV) in multiday cisplatin based regimens. The use of combination of a 5-hydroxytryptamine (HT)3 receptor antagonist, a neurokinin-1 (NK1) antagonist, and dexamethasone has greatly improved our ability to prevent and control acute and delayed CINV. Mechanism and pattern of CINV with multiday chemotherapy may differ from those in single day chemotherapy and therefore efficacy of antiemetic drugs as observed in single day chemotherapy may not be applicable. There are only few randomized clinical trials with special emphasis on multiday chemotherapy. Further studies are essential to determine the efficacy, optimal dose, and duration of the newer agents and combinations in multiday cisplatin based chemotherapy. PMID:26425563

    Experimental chemotherapy and radiotherapy were tried in transplanted tumors derived from a paratesticular embryonal rhabdomyosarcoma. There was no significant difference on the therapeutic effect between a combination chemotherapy composed of vincristine, actinomycin D and cyclophosphamide, so-called VAC regimen, and a single therapy of radiation. However, morphologic analyses suggest that VAC is effective in embryonal rhabdomyosarcomas in which undifferentiated rhabdomyoblasts predominate, while radiotherapy is preferable for those containing variously differentiated rhabdomyoblasts.

    We present 2 patients who developed spontaneous pneumothorax (SP) following rapid regression of lymphoma and rhabdomyosarcoma with lung metastases. Case 1, a 43-year old man was admitted to our hospital with dyspnea 10 days before admission. He denied any recent trauma or previous treatment for lung tuberculosis. Three weeks prior to admission, he received first cycle of CHOP for non-Hodgkin's lymphoma stage II BE. Chest X-ray consistent with right pneumothorax. After treatment with chest tube drainage for about 1 month, the patient recovered and chemotherapy could be continued without further complications. Case 2, a 35- year old man was admitted to other hospital with dyspnea and chest pain on day 4 after second cycle of systemic combined chemotherapy for rhabdomyosarcoma stage IV (lung metastases) with doxorubicin, ifosfamide, mesna, and dacarbazine. Chest X-ray showed hydropneumothorax on right and left lung. After treatment with chest tube drainage about 2 weeks, the patient recovered and chemotherapy could be continued without further complications. The mechanism of pneumothorax following chemotherapy is not clearly understood yet, however, several hypotheses have been considered: 1) the rupture of a subpleural bulla after chemotherapy; 2) the rupture of an emphysematous bulla in an over expanded portion of the lung which is partially obstructed by a neoplasm; 3) tumor lyses or necrosis due to cytotoxic chemotherapy directly induces the formation of fistula. Dyspnea and chest pain suddenly appear during successful chemotherapy for metastatic chemosensitive tumors should alert the physician to the possibility of SP. The treatment is directed toward lung re-expansion. Chemotherapy induced pneumothorax should be considered as oncologic emergency. PMID:27550883

    While chemotherapeutic agents have yielded relative success in the treatment of cancer, patients are often plagued with unwanted and even debilitating side-effects from the treatment which can lead to dose reduction or even cessation of treatment. Common side effects (symptoms) of chemotherapy include (i) cognitive deficiencies such as problems with attention, memory and executive functioning; (ii) fatigue and motivational deficit; and (iii) neuropathy. These symptoms often develop during treatment but can remain even after cessation of chemotherapy, severely impacting long-term quality of life. Little is known about the underlying mechanisms responsible for the development of these behavioral toxicities, however, neuroinflammation is widely considered to be one of the major mechanisms responsible for chemotherapy-induced symptoms. Here, we critically assess what is known in regards to the role of neuroinflammation in chemotherapy-induced symptoms. We also argue that, based on the available evidence, neuroinflammation is unlikely the only mechanism involved in the pathogenesis of chemotherapy-induced behavioral toxicities. We evaluate two other putative candidate mechanisms. To this end we discuss the mediating role of damage-associated molecular patterns (DAMPs) activated in response to chemotherapy-induced cellular damage. We also review the literature with respect to possible alternative mechanisms such as a chemotherapy-induced change in the bioenergetic status of the tissue involving changes in mitochondrial function in relation to chemotherapy-induced behavioral toxicities. Understanding the mechanisms that underlie the emergence of fatigue, neuropathy, and cognitive difficulties is vital to better treatment and long-term survival of cancer patients. PMID:25954147

    Treatment with (neo)adjuvant chemotherapy for breast cancer, as currently given, causes cell damage by induction of double-strand DNA breaks. Because BRCA1 and BRCA2 proteins play a role in the repair of DNA damage, the efficacy of (neo)adjuvant chemotherapy may be increased in BRCA1/2-associated breast cancer patients. As a downside, acute chemotherapy-related toxicity may also be increased. We selected all female patients who were treated at the Erasmus MC Cancer Institute, with (neo)adjuvant chemotherapy for primary or locoregional recurrence of breast cancer (PBC/LR) between January 1, 2004 and December 31, 2014. The primary outcome was the relative total dose intensity (RTDI), calculated for anthracyclines and taxanes separately. Secondary outcomes were the occurrence of febrile neutropenia, delay in chemotherapy administration, and switch to another chemotherapy regimen due to toxicity. In total, 701 patients treated for PBC/LR were eligible for data analyses, among which 85 BRCA1/2 mutation carriers (n = 67 BRCA1 and n = 18 BRCA2). The mean RTDI for anthracyclines was not significantly different between both groups (98.7 % in the BRCA1/2, 96.6 % in the sporadic group, p = 0.27). Also the mean RTDI for taxanes was not significantly different between the groups (93.6 % in the BRCA1/2-associated, 90.0 % in the sporadic group, p = 0.12). Linear regression analysis revealed no significant effect of BRCA1/2 mutation carriership on the RTDIs. No significant differences were found in the percentages of patients presenting with febrile neutropenia, having a delay in chemotherapy administration or switching to an altered chemotherapy regimen. Additionally, the odds ratios showed no significant effect of BRCA1/2 mutation carriership on the secondary outcome variables. (Neo)adjuvant chemotherapy-related toxicity was not different between BRCA1/2-associated and sporadic breast cancer patients suggesting that the DNA damage repair mechanism of non-cancer cells

    The adjuvant treatment of patients with stage II colon cancer is an area of controversy in medical oncology. Adjuvant chemotherapy aims to eradicate micrometastatic disease present at the time of surgery, preventing the development of distant metastatic disease and thereby curing those patients of their cancer. National and international guidelines for the adjuvant treatment of stage II colon cancer recommend a range of treatment options from observation to chemotherapy with single-agent or combination regimens, depending on the presence or absence of high-risk features (poorly differentiated histology, presence of lymphovascular invasion, presence of perineural invasion, report of < 12 lymph nodes, bowel obstruction, localized perforation, or positive margins). In the one prospective study designed to address the role of adjuvant chemotherapy in stage II colon cancer, a small but statistically significant benefit in overall survival was seen for those patients who received adjuvant chemotherapy; however, multiple meta-analyses and retrospective subgroup analyses have called these findings into question. Though there may be a role for adjuvant chemotherapy in the treatment of patients with stage II colon cancer, its incremental benefit is small, at best, and comes with the risks of real and rarely fatal complications of chemotherapy.

    Background: Metronomic chemotherapy consisting of methotrexate and celecoxib recently has shown promising results in multiple studies in head and neck cancers. However, these studies have not included patients with maxillary sinus primaries. Hence, the role of palliative metronomic chemotherapy in patients with maxillary sinus carcinoma that is not amenable to radical therapy is unknown. Methods: This was a retrospective analysis of carcinoma maxillary sinus patients who received palliative metronomic chemotherapy between August 2011 and August 2014. The demographic details, symptomatology, previous treatment details, indication for palliative chemotherapy, response to therapy, and overall survival (OS) details were extracted. SPSS version 16 was used for analysis. Descriptive statistics have been performed. Survival analysis was done by Kaplan–Meier method. Results: Five patients had received metronomic chemotherapy. The median age was 60 years (range 37–64 years). The proportion of patients surviving at 6 months, 12 months, and 18 months were 40%, 40%, and 20%, respectively. The estimated median OS was 126 days (95% confidence interval 0–299.9 days). The estimated median survival in patients with an event-free period after the last therapy of <6 months was 45 days, whereas it was 409 days in patients with an event-free period postlast therapy above 6 months (P = 0.063). Conclusion: Metronomic chemotherapy in carcinoma maxillary sinus holds promise. It has activity similar to that seen in head and neck cancers and needs to be evaluated further in a larger cohort of patients.

    Everyday more and more people are diagnosed with some form of cancer. Some are treatable with chemotherapy alone, while others need radiotherapy and occasionally surgery. Recently, concurrent administration of chemotherapy and radiotherapy has been increasingly used in cancer treatment, leading to improvements in survival as well as quality of life. Accordingly, interaction of chemotherapy drugs with radiation will be meaningful to examine. In the present study, gamma ray energy absorption and exposure of buildup factors were computed using the five-parameter geometric progression (G-P) fitting formula for some chemotherapy drugs in the energy range 0.015-15 MeV, and for penetration depths up to 40 mean free path (mfp). The generated energy absorption (EABF) and exposure buildup factors (EBF) of chemotherapy drugs have been studied as a function of penetration depth and incident photon energy. The significant variations in EABF and EBF for chemotherapy drugs have been observed at the moderate energy region. It has been concluded that the buildup of photons is less in azathioprine and is more in vinblastine compared with other drugs. Buildup factors investigated in the present work could be useful in radiation dosimetry and therapy. PMID:25661335

    The present study reports the case of a 28-year-old male who was diagnosed with sigmoid colon carcinoma and exhibited local recurrence following radical surgery and 6 cycles of adjuvant chemotherapy. The primary surgery consisted of a partial sigmoidectomy and bladder repair. At 8 months post-chemotherapy, the patient was referred to Nanjing Drum Tower Hospital (Nanjing, China) due to local recurrence at the anastomotic site, which was confirmed by colonoscopy and total abdominal computed tomography. Synchronous intensity modulation radiation therapy and intraperitoneal (IP) perfusion chemotherapy with irinotecan (100 mg/m2) was administered. Following treatment, the object efficacy evaluation revealed a complete response and a second resection of the remaining sigmoid colon was performed. The post-operative results showed a pathological complete response. This case indicated that a combination of therapies, including radiotherapy, IP perfusion chemotherapy and surgery, may be beneficial and effective in patients with recurrent colon cancer.

    Acute lymphoblastic leukemia (ALL) is an aggressive hematological tumor resulting from the malignant transformation of lymphoid progenitors. Despite intensive chemotherapy, 20% of pediatric and over 50% of adult ALL patients fail to achieve a complete remission or relapse after intensified chemotherapy, making disease relapse and resistance to therapy the most significant challenge in the treatment of this disease1,2. Using whole exome sequencing, here we identify mutations in the cytosolic 5'-nucleotidase II gene (NT5C2), which encodes a 5'-nucleotidase enzyme responsible for inactivation of nucleoside analog chemotherapy drugs, in 20/103 (19%) relapse T-ALLs and in 1/35 (3%) relapse B-precursor ALLs analyzed. NT5C2 mutant proteins show increased nucleotidase activity in vitro and conferred resistance to chemotherapy with 6-mercaptopurine and 6-thioguanine when expressed in ALL lymphoblasts. These results support a prominent role for activating mutations in NT5C2 and increased nucleoside analog metabolism in disease progression and chemotherapy resistance in ALL. PMID:23377281

    Canine appendicular osteosarcoma is an important clinical problem in veterinary medicine. Current standard therapy includes amputation followed by chemotherapy, which improves outcomes; however the percentage of long-term survival is still relatively low at 15-20%. Established prognostic factors include serum alkaline phosphatase level, histologic grade, and lymphocyte and monocyte counts. We used a protocol with shorter inter-treatment intervals than standard, but which we expected to still be well-tolerated, based on drugs known to be active agents, with the aim of improving outcomes by increasing dose intensity. Thirty-eight dogs with confirmed appendicular osteosarcoma and no pulmonary metastases that underwent amputation followed by this chemotherapy protocol were retrospectively evaluated. The median survival time was 317 days and 1- and 2-yr survival percentages were 43.2% and 13.9%, respectively. Toxicity was comparable to that seen with other standard dose protocols, with 5.2% of dogs hospitalized for complications that resolved with supportive care and no chemotherapy-related mortality. Serum alkaline phosphatase level (normal or high) (p = 0.004) and whether or not chemotherapy was completed (p = 0.001) were found to significantly impact survival time on multivariate analysis. Outcomes were similar to those reported with most other published chemotherapy protocols for dogs with this disease. PMID:27008320

    Neoadjuvant chemotherapy has more and more become clinical routine during the past years. Results from large randomized trials like NSABP-B18 show that survival parameters are not affected if sequence of therapy is changed. Survival parameters have been intensively studied, but surgical standards after primary chemotherapy are much less well defined. Results from the early trials comparing lumpectomy or quadrantectomy with mastectomy are generally transposed to the neoadjuvant situation. In this context the "result of downstaging" is surgically treated like otherwise the primary tumor would have been treated. Though local recurrence rates reported after primary chemotherapy are not increased within the whole population this may not be correct for subgroups. E.g. within the NSABP-B18 trial significantly higher local recurrence rates are reported for those patients who initially were proposed to have mastectomy and who actually received lumpectomy after effective primary chemotherapy. Another unresolved problem is surgery after complete remission, which as histopathology demonstrates corresponds often not to pathological complete remission. Therefore in most cases the initially involved area is resected, which may result in a more radical surgical approach to complete remission than to partial remission. Further standardisation of surgical approach to patients after neoadjuvant chemotherapy should be evaluated within phase III trials. PMID:10857211

    Summary The current clinical application of combination chemotherapy is guided by a historically successful set of practices that were developed by basic and clinical researchers 50-60 years ago. Thus, in order to understand how emerging approaches to drug development might aid the creation of new therapeutic combinations, it is critical to understand the defining principles underlying classic combination therapy and the original experimental rationales behind them. One such principle is that the use of combination therapies with independent mechanisms of action can minimize the evolution of drug resistance. Another is that in order to kill sufficient cancer cells to cure a patient, multiple drugs must be delivered at their maximum tolerated dose – a condition that allows for enhanced cancer cell killing with manageable toxicity. In light of these models, we aim to explore recent genomic evidence underlying the mechanisms of resistance to the combination regimens constructed on these principles. Interestingly, we find that emerging genomic evidence contradicts some of the rationales of early practitioners in developing commonly used drug regimens. However, we also find that the addition of recent targeted therapies has yet to change the current principles underlying the construction of anti-cancer combinatorial regimens, nor have they made substantial inroads into the treatment of most cancers. We suggest that emerging systems/network biology approaches have an immense opportunity to impact the rational development of successful drug regimens. Specifically, by examining drug combinations in multivariate ways, next generation combination therapies can be constructed with a clear understanding of how mechanisms of resistance to multi-drug regimens differ from single agent resistance.

    Chemotherapy and radiation therapy are commonly used alone or in combination in the curative management of many malignancies in adolescent and adult males. Over the last 15-20 years, the striking success in the treatment of some common cancers in reproductive males has led to increasing concern for damage to normal tissues, such as the testes, resulting from curative cancer treatment. Indeed, a major future goal for cancer treatment will be to improve on the complication-free cure rate. Inherent in achieving this goal is to understand the pathophysiology and clinical expression of testicular injury. Both chemotherapy and radiation therapy result in germ cell depletion with the development of oligo- to azoospermia and testicular atrophy. The type of drug (particularly the alkylating agents), duration of treatment, intensity of treatment, and drug combination are major variables in determining the extent and duration of testicular injury. Testicular injury with chemotherapy also appears to vary with the age of the patient at the time of treatment. Newer drug combinations are now being used which appear to have curative potential in tumors such as Hodgkin's disease and germ cell testicular cancer with less potential for testicular injury. The most accurate and complete information on radiation injury to the testes is derived from two studies of normal volunteers who received graded single doses directly to the testes. A clear dose-response relationship of clinical and histological testicular damage was found with gradual recovery occurring following doses of up to 600 cGy. While these two studies provide an important clinical data base, radiation therapy used in treating cancers involves multiple daily treatments, usually 25-35 delivered over several weeks. Additionally, direct testicular irradiation is seldom used clinically. 37 references.

    Cancer therapies can be associated with significant central nervous system (CNS) toxicity. While radiation-induced brain damage has been long recognized both in pediatric and adult cancer patients, CNS toxicity from chemotherapy has only recently been acknowledged. Clinical studies suggest that the most frequent neurotoxic adverse effects associated with chemotherapy include memory and learning deficits, alterations of attention, concentration, processing speed and executive function. Preclinical studies have started to shed light on how chemotherapy targets the CNS both on cellular and molecular levels to disrupt neural function and brain plasticity. Potential mechanisms include direct cellular toxicity, alterations in cellular metabolism, oxidative stress, and induction of pro-inflammatory processes with subsequent disruption of normal cellular and neurological function. Damage to neural progenitor cell populations within germinal zones of the adult CNS has been identified as one of the key mechanisms by which chemotherapy might exert long-lasting and progressive neurotoxic effects. Based on the important role of the hippocampus for maintenance of brain plasticity throughout life, several experimental studies have focused on the study of chemotherapy effects on hippocampal neurogenesis and associated learning and memory. An increasing body of literature from both animal studies and neuroimaging studies in cancer patients suggests a possible relationship between chemotherapy induced hippocampal damage and the spectrum of neurocognitive deficits and mood alterations observed in cancer patients. This review aims to briefly summarize current preclinical and neuroimaging studies that are providing a potential link between the neurotoxic effects of chemotherapy and hippocampal dysfunction, highlighting challenges and future directions in this field of investigation.

    1994-09-01

    Intensive therapy and autologous marrow or peripheral blood stem cell transplantation is often utilized in Hodgkin's disease patients whose disease has progressed after primary conventional chemotherapy. A number of studies have described long-term disease-free survival in up to 50% of transplanted patients. High-dose chemotherapy conditioning regimens such as "CBV" or "BEAM" have been used more often than regimens containing total body irradiation. Usually unpurged autologous bone marrow has been utilized as the source of hematopoietic stem cell reconstitution, although recently the use of "primed" peripheral blood stem cells has increased markedly. The challenges of transplant-related toxicity and recurrence of disease post-transplant are discussed, as well as possible strategies to reduce these problems. The use of autologous transplantation is discussed in three clinical settings: patients who have failed to enter a complete remission (CR) after primary chemotherapy, those who have relapsed within 12 months of attaining a CR and those who have relapsed after a longer (i.e., > or = 12 months) first CR. When compared with conventional salvage chemotherapy, transplantation appears to produce a higher long-term disease-free survival rate in all of these patient groups. However, assessment of an advantage for autotransplantation, particularly in patients with long first remissions, is difficult without a Phase III trial. On the other hand, recently updated results from our center indicate that 72% of patients relapsing after long initial remissions benefit from autotransplantation at this point in their disease course, and that transplant-related mortality is low in this setting. Other issues addressed include the potential role of autologous transplantation as consolidation therapy in selected high-risk patients in an initial CR, as well as the utility of conventional chemotherapy and involved-field radiotherapy in conjunction with autotransplantation.

    Oncological treatment decision-making is a highly complex enterprise integrating multiple patient, tumor, treatment, and professional factors with the available medical evidence. This management complexity can be exacerbated by the interplay of patient age and comorbid non-cancer conditions that can affect patient quality of life, treatment tolerance, and survival outcomes. Given the expected increase in median age (and associated comorbidity burden) of Western populations over the next few decades, the use of evidence-based therapies that appropriately balance treatment intensity and tolerability to achieve the desired goal of treatment (radical, adjuvant, salvage, or palliative) will be increasingly important to health care systems, providers, and patients. In this review, we highlight the evidence related to age and comorbidity, as it relates to radiotherapy and chemotherapy decision making. We will address evidence as it relates to age and comorbidity considerations separately and also the interplay between the factors. Clinical considerations to adapt radiation and/or chemotherapy treatment to deal with comorbidity challenges will be discussed. Knowledge gaps, future research, and clinical recommendation in this increasingly important field are highlighted as well. PMID:22985810

    Bone marrow transplantation procedure has emerged as an effective treatment for hematological malignancies. However, recurrence of leukemia is still the major cause of treatment failure. Subsequent treatment in this category of patients, generally considered incurable, has not been yet standardized. At our institution, 13 patients, 7 with acute non lymphoid leukemia (ANLL) and 6 with acute lymphoid leukemia (ALL), were treated at relapse after bone marrow transplantation either autologous or allogeneic (AuBMT 8, ABMT 4) performed in complete remission (CR). The interval between BMT and relapse was less than 9 months in 6 patients (2 ABMT and 4 AuBMT) and more than 9 months in 7 patients. Early relapsed patients showed no response to treatment and died at a median of 5.5 months (range 1-13) after relapse. Late relapse after BMT was characterized by a high percentage of response (5 CR and 1 PR), particularly after intensive chemotherapy and by a longer survival (median 14 months; range 2-36). Chemotherapy after transplantation should be carefully evaluated in patients relapsed after BMT in order to select a population that can achieve long term disease free survival. PMID:7858490

    The optimal chemotherapy for thymic carcinoma has yet to be determined based on clinical evidence because of the rarity of this pathological entity. We report the case of a patient with locally advanced thymic carcinoma in whom radical excision was achieved with intensive preoperative chemotherapy followed by curative-intent surgery. A 59-year-old woman was diagnosed with Masaoka-Koga stage III thymic cancer showing squamous cell carcinoma histology. Invasion to the ascending aorta and left brachiocephalic vein was suspected from imaging, so preoperative chemotherapy with three cycles of cisplatin and irinotecan was administered. Partial response to chemotherapy was achieved and the residual tumor was completely resected with subsequent surgery. Histopathological examination of the resected specimen demonstrated stage II thymic carcinoma. The patient has shown no evidence of recurrence or surgical complications as of 46 months after completing preoperative chemotherapy. PMID:22760255

    Background Endometrial adenocarcinoma (womb cancer) is a malignant growth of the lining (endometrium) of the womb (uterus). It is distinct from sarcomas (tumours of the uterine muscle). Survival depends the risk of microscopic metastases after surgery. Adjuvant (postoperative) chemotherapy improves survival from some other adenocarcinomas, and there is evidence that endometrial cancer is sensitive to cytotoxic therapy. This systematic review examines the effect of chemotherapy on survival after hysterectomy for endometrial cancer. Objectives To assess efficacy of adjuvant (postoperative) chemotherapy for endometrial cancer. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2010, Issue 3), MEDLINE and EMBASE up to August 2010, registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials (RCTs) comparing adjuvant chemotherapy with any other adjuvant treatment or no other treatment. Data collection and analysis We used a random-effects meta-analysis to assess hazard ratios (HR) for overall and progression-free survival and risk ratios (RR) to compare death rates and site of initial relapse. Main results Five RCTs compared no additional treatment with additional chemotherapy after hysterectomy and radiotherapy. Four trials compared platinum based combination chemotherapy directly with radiotherapy. Indiscriminate pooling of survival data from 2197 women shows a significant overall survival advantage from adjuvant chemotherapy (RR (95% CI) = 0.88 (0.79 to 0.99)). Sensitivity analysis focused on trials of modern platinum based chemotherapy regimens and found the relative risk of death to be 0.85 ((0.76 to 0.96); number needed to treat for an additional beneficial outcome (NNT) = 25; absolute risk reduction = 4% (1% to 8%)). The HR for overall survival is 0.74 (0.64 to 0.89), significantly

    Abstract This study aimed to assess the efficacy and safety of bevacizumab plus preoperative chemotherapy as first-line treatment for liver-only metastatic colorectal cancer in Chinese patients compared with those of preoperative chemotherapy alone. Patients with histologically confirmed liver-only metastatic colorectal cancer were sequentially reviewed, and received either preoperative chemotherapy plus bevacizumab (bevacizumab group, n = 32) or preoperative chemotherapy alone (chemotherapy group, n = 57). Progression-free survival, response rate, liver resection rate, conversion rate, and safety were analyzed. With median follow-up of 28.7 months, progression-free survival was 10.9 months (95% confidence interval: 8.7–13.1 months) in bevacizumab group and 9.9 months (95% confidence interval: 6.8–13.1 months) in chemotherapy group (P = 0.472). Response rates were 59.4% in bevacizumab group and 38.6% in chemotherapy group (P = 0.059). Overall liver resection (R0, R1, and R2) rate was 68.8% in bevacizumab group and 54.4% in chemotherapy group (P = 0.185). Conversion rate was 51.9% in bevacizumab group and 40.4% in chemotherapy group (P = 0.341). No postoperative complication was observed in all patients. Bevacizumab plus preoperative chemotherapy as first-line treatment for liver-only metastatic colorectal cancer tends to achieve better clinical benefit with controllable safety in Chinese patients.

    Adenocarcinoma of the rectum represents about a third of cases of colorectal cancer, with an annual incidence of 12,000 cases in France. On the contrary of colon cancer, the benefice of adjuvant chemotherapy in rectal cancer has not been definitively proved, more because this question was assessed in few recent studies than because negative results. Preoperative radiochemotherapy is now the reference treatment for mid and lower rectal cancers, and allow to increase the local control without improvement of progression free survival and overall survival. The data of the "historical studies" of adjuvant treatment in rectal cancer published before 1990, of the meta-analysis of adjuvant trials in rectal cancer and of the QUASAR study suggest that adjuvant chemotherapy with fluoropyrimidines (intravenous or oral), in absence of pre-operative treatment, decrease the risk of metastatic relapse after curative surgery for a rectal cancer of stage II or III. This benefice seems similar to the one observed in colon cancer. In the EORTC radiotherapy group trial 22921, an adjuvant chemotherapy with 5-fluorouracil and low dose of leucovorin was not associated with a significantly improvement of overall survival but, despite the fact that only 42.9% of patients received all planed cycles, the progression free survival was increased (not significantly) in groups receiving adjuvant chemotherapy. The French recommendations are to discuss the indication of adjuvant chemotherapy by fluoropyrimidines in cases of stage III rectal cancer on histopathologic reports and no chemotherapy in case of stade II. Despite the fact that none study have assessed a combination of fluoropyrimidines and oxaliplatin in adjuvant setting in rectal cancer, like in colon cancer, the Folfox4, modified Folfox6 or Xelox regimens are valid options in stage III (experts opinion). In cases of pathologic complete remission or in absence of involved nodes, the benefice of adjuvant chemotherapy is not assessed. In

    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

    From December 1986 to April 1990, 40 consecutive ovarian cancer patients who relapsed after response to cisplatin-based chemotherapy regimens were treated with seven courses of weekly cisplatin, in combination with epirubicin or etoposide. The overall response rate obtained with the intensive schedule was 60% and the complete response rate was 25%; median duration of response was 7 months and median survival time, 13.5 months. Responsive cases seem to have longer survival; a prognostic factor for response to salvage treatment and longer survival is the disease-free interval after the first-line chemotherapy. Weekly cisplatin as intensive treatment was very well tolerated and showed acceptable toxicity in both the combination protocols with epirubicin or etoposide. PMID:1959783

    Psychological distress is a common problem among patients with cancer, yet it mostly goes unreported and untreated. This study examined the association of a psycho-educational intervention with the psychological distress levels of breast cancer and cervical cancer patients undergoing chemotherapy. The design of the study was quasi-experimental, pretest-posttest design with a comparison group. One hundred patients at a cancer hospital in Jakarta, Indonesia, completed Distress Thermometer screening before and after chemotherapy. Fifty patients in the intervention group were given a psycho-educational video with positive reappraisal, education and relaxation contents, while receiving chemotherapy. Patients who received the psycho-educational intervention had significantly lower distress levels compared with those in the control group. Routine distress screening, followed by distress management and outcome assessment, is needed to improve the wellbeing of cancer patients. PMID:26911178

    Chemotherapy, one of the mainstays of cancer treatment today, was pioneered at Yale during World War II. Last year, two Yale surgeons, Drs. John Fenn and Robert Udelsman, sought to unearth the mystery surrounding the discovery of chemotherapy and its first use at Yale. The first chemotherapy patient is known only as JD in the literature, and without a name, date of birth, or medical record number, a search for his record seemed futile. However, persistence coupled with sheer fortune led them to JD’s chart, where they found information that differed from previous accounts. The riveting personal story of JD, an immigrant patient with lymphosarcoma, was revealed for the first time by Drs. Fenn and Udelsman on January 19, 2011, at a special Surgical Grand Rounds celebrating the bicentennial of Yale School of Medicine. PMID:21698052

    Advances in the diagnosis and treatment of pediatric malignancies have substantially increased the number of childhood cancer survivors. However, reports suggest that some of the chemotherapy agents used for treatment can cross the blood brain barrier which may lead to a host of neurological symptoms including oculomotor dysfunction. Whether chemotherapy at young age causes oculomotor dysfunction later in life is unknown. Oculomotor performance was assessed with traditional and novel methods in 23 adults (mean age 25.3 years, treatment age 10.2 years) treated with chemotherapy for a solid malignant tumor not affecting the central nervous system. Their results were compared to those from 25 healthy, age-matched controls (mean age 25.1 years). Correlation analysis was performed between the subjective symptoms reported by the chemotherapy treated subjects (CTS) and oculomotor performance. In CTS, the temporal control of the smooth pursuit velocity (velocity accuracy) was markedly poorer (p<0.001) and the saccades had disproportionally shorter amplitude than normal for the associated saccade peak velocity (main sequence) (p = 0.004), whereas smooth pursuit and saccade onset times were shorter (p = 0.004) in CTS compared with controls. The CTS treated before 12 years of age manifested more severe oculomotor deficits. CTS frequently reported subjective symptoms of visual disturbances (70%), unsteadiness, light-headedness and that things around them were spinning or moving (87%). Several subjective symptoms were significantly related to deficits in oculomotor performance. To conclude, chemotherapy in childhood or adolescence can result in severe oculomotor dysfunctions in adulthood. The revealed oculomotor dysfunctions were significantly related to the subjects' self-perception of visual disturbances, dizziness, light-headedness and sensing unsteadiness. Assessments of oculomotor function may, thus, offer an objective method to track and rate the level of neurological

The revealed oculomotor dysfunctions were significantly related to the subjects’ self-perception of visual disturbances, dizziness, light-headedness and sensing unsteadiness. Assessments of oculomotor function may, thus, offer an objective method to track and rate the level of neurological

    We demonstrate that IR spectroscopic analysis can be used in diagnosis and chemotherapy monitoring for cancers of various organs at the molecular level. We used Fourier transform IR spectroscopy to study human breast and thyroid tumor tissues which were removed during surgery. The characteristic frequencies of C = O stretching vibrations in the IR spectra of tissues of pathological foci were compared with data from histological examination. In the IR spectra of healthy tissues or for benign tumors, the most intense absorption bands ν(C = O) are located in the interval 1675-1650 cm-1. When malignant neoplasms are present in the organs, the intensity of the bands in this range of the spectrum is reduced, while the intensities of the absorption bands in the 1710-1680 cm-1 interval increase. We also studied lung tissue for mice of the C57B1/6 line for healthy tissue and after implantation of B-16 melanoma tumor. The IR spectra of healthy mouse lung tissue and mouse lung tissue with B-16 melanoma metastases in the region of the C = O stretching vibrations display the same differences. We found that when lung malignancy was treated with the optimal dose of a synthesized drug based on palladium complexes of methylenediphosphonic acid, the spectroscopic signs of the presence of metastases in the lungs disappear, and the IR spectrum of the lung tissue after treatment practically coincides with the spectrum of healthy lung tissue.

    The main progress in the management of soft tissue sarcomas have been obtained in the field of local control. Although the main evolutive, vital, risk of these diseases is metastatic dissemination, efficacy of adjuvant chemotherapy remains a controversial issue. Thus, adjuvant chemotherapy cannot be considered as a standard for any situation. The last results of clinical trials, meta-analysis and population studies are presented and discussed in this article. New therapeutic strategies are to be developed to prevent metastases in soft tissue sarcomas. This needs a better understanding of the biology of those tumors, of metastases risk factors and of the determinants of systemic therapies efficacy in these tumors. PMID:20547481

    The main methods of treatment for cervical cancer are surgery, radiotherapy or their combination. During past two decades chemotherapy are increasingly being used not only in patients with disseminated forms of this disease but also in patients undergoing chemoradiotherapy or as induction therapy. Possibilities of adjuvant chemotherapy for cervical cancer are being studied. According to A.D.Kaprin and V.V. Starinskiy in 2013 in Russia, 32% of patients with newly diagnosed cervical cancer underwent only radiation therapy, 32%--combined or complex treatment, 27.3%--only surgery, and just 8.7%--chemoradiotherapy.

    Thymic malignancies are rare epithelial tumors that may be aggressive and difficult to treat. Thymomas are usually localized to the anterior mediastinum and are frequently eligible for upfront surgical resection. However, nearly 30% of patients present with locally advanced tumors at time of diagnosis, and chemotherapy is then used to reduce the tumor burden, possibly allowing subsequent surgery and/or radiotherapy. Metastatic and recurrent thymic malignancies may similarly be treated with chemotherapy. More recently, the molecular characterization of thymoma and thymic carcinoma led to the identification of potentially druggable targets, laying the foundations to implement personalized medicine for patients.

    Ninety-eight patients with locally advanced breast cancer (Stage IIIA-IIIB) were entered into a pilot study combining intensive induction (neoadjuvant) chemotherapy (VTMFAP) with or without hormonochemotherapy, external and interstitial radiotherapy, and consolidation chemotherapy with or without hormonochemotherapy. Tumor regression over 50% was observed in 91% patients after chemotherapy, and complete clinical remission occurred in 100% patients after irradiation. The rate of local relapse is 13%. The 3-year disease-free survival is 62% and 3-year global survival is 77%. Initial chemotherapeutic tumor regression greater than 75% is the main predictive factor for disease-free survival.

  8. Effects of virtual reality on symptom distress in children receiving chemotherapy.

    1999-01-01

    This study tested the premise that virtual reality (VR) as a distraction intervention could mitigate chemotherapy-related symptom distress in children with cancer aged 10-17 years. Cancer treatments are intensive and difficult to endure. Distraction interventions are effective because the individual concentrates on pleasant or interesting stimuli instead of focusing on unpleasant symptoms. VR as a distraction intervention is both immersive and interactive. For this study the individual wore a Virtual IO(R) headset during a single intravenous chemotherapy treatment. Participants chose one of three commercially available, CD ROM-based scenarios: Magic Carpet, Sherlock Holmes Mystery, and Seventh Guest(R). An interrupted time series design with removed treatment was used to answer these research questions: (1) Is VR an effective distraction intervention for reducing chemotherapy-related symptom distress in children? and (2) Does VR have a lasting effect? The convenience sample consisted of 11 children receiving outpatient chemotherapy. The Symptom Distress Scale (SDS) and the State-Trait Anxiety Inventory for Children (STAIC-1) were used to measure the dependent variable of symptom distress. Repeated-measures ANOVA were used for data analysis. Data analysis of the SDS suggested that the VR intervention was effective at reducing the level of symptom distress immediately following the chemotherapy treatment (p <.10), but did not have a lasting effect. Analysis of the STAIC-1 demonstrated high levels of anxiety during the initial chemotherapy treatment that decreased during subsequent treatments. State anxiety levels were not influenced by the VR intervention. This study supports the application of VR as a distraction intervention. PMID:19178248

    The management of retinoblastoma (RB) has dramatically changed over the past two decades from previous radiotherapy methods to current chemotherapy strategies. RB is a remarkably chemotherapy-sensitive tumor. Chemotherapy is currently used as a first-line approach for children with this malignancy and can be delivered by intravenous, intra-arterial, periocular, and intravitreal routes. The choice of route for chemotherapy administration depends upon the tumor laterality and tumor staging. Intravenous chemotherapy (IVC) is used most often in bilateral cases, orbital RB, and as an adjuvant treatment in high-risk RB. Intra-arterial chemotherapy (IAC) is used in cases with group C or D RB and selected cases of group E tumor. Periocular chemotherapy is used as an adjunct treatment in eyes with group D and E RB and those with persistent/recurrent vitreous seeds. Intravitreal chemotherapy is reserved for eyes with persistent/recurrent vitreous seeds. In this review, we describe the various forms of chemotherapy used in the management of RB. A database search was performed on PubMed, using the terms "RB," and "treatment," "chemotherapy," "systemic chemotherapy," "IVC," "IAC," "periocular chemotherapy," or "intravitreal chemotherapy." Relevant English language articles were extracted, reviewed, and referenced appropriately. PMID:25827539

    Although acute myeloid leukemia (AML) is primarily a disease of older adults (age ≥60 years), the optimal treatment for older adults remains largely undefined. Intensive chemotherapy is rarely beneficial for frail older adults or those with poor-risk disease, but criteria that define fitness and/or appropriateness for intensive chemotherapy remain to be standardized. Evaluation of disease-related and patient-specific factors in the context of clinical decision making has therefore been largely subjective. A uniform approach to identify those patients most likely to benefit from intensive therapies is needed. Here, we review currently available objective measures to define older adults with AML who are ineligible for intensive chemotherapy, and discuss promising investigational approaches. PMID:26697412

  13. Neoadjuvant and Adjuvant Chemotherapy of Cervical Cancer.

    PubMed

    Mallmann, Peter; Mallmann, Christoph

    2016-01-01

    Neoadjuvant chemotherapy is indicated in patients who can tolerate the side effects of a chemotherapy and with preoperative presentation of one of the following clinical risk situations: bulky disease with a maximal tumor diameter of > 4 cm, suspicious lymph nodes in magnetic resonance imaging (MRI), computed tomography (CT) scan or endosonography, histopathologically confirmed lymph node metastasis, or histopathologically documented risk factors such as G3 and L1V1. A neoadjuvant chemotherapy followed by surgery should be performed with cisplatin at a dosage of > 25 mg/m2 per week and an application interval of < 14 days. The previously published data suggests an improved rate of complete resection and reduced incidences of positive lymph nodes and parametric infiltration. Accordingly, the percentage of patients in need for adjuvant radiochemotherapy after operation can be significantly reduced. Some studies demonstrated a prolongation of progression-free and overall survival. Following the previously published studies, adjuvant chemotherapy after operation or after radiochemotherapy has no significant effect on the overall survival and, following the current guidelines, should be avoided.

  14. New therapies for antiemetic prophylaxis for chemotherapy.

    PubMed

    2016-01-01

    A number of new advances have occurred over the past 2 years in the management of chemotherapy-related nausea and vomiting (CINV). A new neurokinin-1 receptor antagonist (NK1RA), netupitant, has been combined with palonosetron in a single oral tablet for treating the effects of moderately emetogenic chemotherapy (MEC) and highly emetogenic chemotherapy (HEC). Rolapitant, another NK1RA, unlike aprepitant, has a long half-life and does not block CYP-3A4 and therefore has fewer drug interactions. Olanzapine reduces nausea more effectively than aprepitant in patients who are receiving HEC and is a better rescue antiemetic than is metoclopramide. Ginger lacks efficacy as an antiemetic agent for CINV. Although there was some evidence in a pilot study of gabapentin as an antiemetic, it was no better in reducing CINV than was placebo. Compliance to guidelines in multiple settings ranges from 50%-60% but is improved by computerized order entry of antiemetics and recommendations displayed with chemotherapy. PMID:26870838

  15. TGFβ restores hematopoietic homeostasis after myelosuppressive chemotherapy

    PubMed Central

    Brenet, Fabienne; Kermani, Pouneh; Spektor, Roman; Rafii, Shahin

    2013-01-01

    Myelosuppression is a life-threatening complication of antineoplastic therapy, but treatment is restricted to a few cytokines with unilineage hematopoietic activity. Although hematopoietic stem cells (HSCs) are predominantly quiescent during homeostasis, they are rapidly recruited into cell cycle by stresses, including myelosuppressive chemotherapy. Factors that induce HSCs to proliferate during stress have been characterized, but it is not known how HSC quiescence is then reestablished. In this study, we show that TGFβ signaling is transiently activated in hematopoietic stem and progenitor cells (HSPCs) during hematopoietic regeneration. Blockade of TGFβ signaling after chemotherapy accelerates hematopoietic reconstitution and delays the return of cycling HSCs to quiescence. In contrast, TGFβ blockade during homeostasis fails to induce cycling of HSPCs. We identified the cyclin-dependent kinase inhibitor Cdkn1c (p57) as a key downstream mediator of TGFβ during regeneration because the recovery of chimeric mice, incapable of expressing p57 in HSPCs, phenocopies blockade of TGFβ signaling after chemotherapy. This study demonstrates that context-dependent activation of TGFβ signaling is central to an unrecognized counterregulatory mechanism that promotes homeostasis once hematopoiesis has sufficiently recovered from myelosuppressive chemotherapy. These results open the door to new, potentially superior, approaches to promote multilineage hematopoietic recovery by blocking the TGFβ signaling that dampens regeneration. PMID:23440043

    2010-01-01

    Background and Purpose The impact of cancer and its treatments on balance and functional mobility in older adults remains unknown but is increasingly important, given the evolution of cancer treatments. Subacute and more persistent side effects such as chemotherapy-induced peripheral neuropathy are on the rise, and the effects on mobility and balance, as well as the prognosis for resolution of any functional deficits, must be established before interventions can be trialed. The purpose of this case report is to describe the severity and long-term persistence of mobility decline in an older adult who received neurotoxic chemotherapy. To our knowledge, this is the first case report to describe an older adult with chemotherapy-induced peripheral neuropathy using results of standardized balance and mobility tests and to focus on prognosis by repeating these measures more than 2 years after chemotherapy. Case Description An 81-year-old woman received a neurotoxic agent (paclitaxel) after curative mastectomy for breast cancer. Baseline testing prior to taxane therapy revealed a socially active woman with no reported functional deficits or neuropathic symptoms, 1.2-m/s gait speed, and performance at the ceiling on balance and gait portions of a standardized mobility measure. Outcomes After 3 cycles, paclitaxel therapy was stopped by the oncologist because of neurotoxicity. Declines as large as 50% were seen in performance-based measures at 12 weeks and persisted at 2.5 years, and the patient reported recurrent falls, cane use, and mobility-related disability. Discussion This case highlights the extent to which function can decline in an older individual receiving neurotoxic chemotherapy, the potential for these deficits to persist years after treatment is stopped, and the need for physical therapy intervention and further research in this population.

    PubMed

    1998-12-01

    Treatment with cytotoxic chemotherapy and radiotherapy is associated with significant gonadal damage in men and women. Alkylating agents such as cyclophosphamide and procarbazine are the most common agents implicated. The vast majority of men receiving procarbazine-containing regimens for the treatment of lymphomas become permanently infertile. Cisplatin-based chemotherapy for testicular cancer results in temporary azoospermia in most men, with a recovery of spermatogenesis in about 50% after 2 years and in 80% after 5 years. There is also evidence of Leydig cell impairment in a proportion of these men, although the clinical significance of this is not clear. The germinal epithelium is very sensitive to radiation-induced damage, with changes to spermatogonia occurring following as little as 0.1 Gy and permanent infertility after fractionated doses of 2 Gy and above. Cytotoxic-induced premature ovarian failure is age- and drug-dependent and ensues in approximately half of women treated with procarbazine-containing chemotherapy for lymphomas. High-dose chemotherapy, total body irradiation, and irradiation at an ovarian dose above 6 Gy usually result in permanent ovarian failure. The course of ovarian function after chemotherapy is variable, and late recovery occurs in some patients. Several methods of preserving gonadal function during potentially sterilizing treatment have been considered. Currently, sperm banking remains the only proven method in men, although hormonal manipulation to enhance the recovery of spermatogenesis and cryopreservation of testicular germ cells are possibilities for the future. Transposition of the ovaries to allow better shielding during radiotherapy is of use in some women, and the prospect of cryopreservation and reimplantation of ovarian tissue is promising.

    The aim of this study is to evaluate the effects of preoperative chemotherapy with fluorouracili polyphase liposome composita pro orale (FPLC) on the tumour cells and the survival rate of the patients with gastric cardia cancer. Sixty patients with gastric cardia cancer were randomly divided into two groups. Thirty patients were treated with FPLC prior to surgical resection, the other 30, as controls, did not receive the preoperative chemotherapy. Pathological responses of the tumours to the FPLC chemotherapy were determined by gross and microscopic assessments of tumour size, tumour emboli, cell degeneration and necrosis. Expressions of nm23 and CD44 were detected by flow cytometry. All patients were followed up to 5 years. In the FPLC-treated patients, the tumour size (p<0. 01), the number of tumour emboli (p=0.04) and the intensity of CD44 expression (p<0.001), were significantly reduced, while cell degeneration (p<0.001), necrosis (p<0.01) and the expression of nm23 (p<0.001) were increased, when compared with those observations seen in the controls. The postoperative 5-year survival rate was 40% in the FPLC-treated group and 23% in the controls (p=0.17). Preoperative FPLC chemotherapy might improve the survival rate of patients with gastric cardia cancer by inhibiting tumour proliferative, invasive and metastatic activities, and stimulating the patient's immune system.

    New cases of invasive cancer in the United States occur among nearly 1.5 million people annually. In 2007, more than 1,500 people died per day with this diagnosis. Cancer is responsible for nearly one in every four deaths reported in the country. Enormous amounts of money and research have been, and are being spent, in an attempt to improve these numbers. While prevention and early detection remain the key to long-term success, treatment in the neo-adjuvant, adjuvant and metastatic settings still centre around two main treatment modalities – radiation therapy and chemotherapy. This article will review the advances that have been made in both areas that are making these treatments more precise and convenient, as well as less toxic, for the patient. In the field of radiation therapy this involves the development of new therapy planning and delivery systems, such as intensity-modulated radiation therapy (IMRT), and positron emission and computed tomography, PET-CT. Chemotherapy has also evolved with the development of targeted chemotherapy for the treatment of specific malignancies as well as improved supportive care agents which allow for the administration of dose-dense chemotherapy when appropriate.

    The prognosis of advanced gastric cancer (AGC) remains poor despite therapeutic advances in recent decades. Several recent positive phase III trials established the efficacy of second-line chemotherapy for metastatic gastric cancer in prolonging overall survival. However, malnutrition and poor performance of AGC in late stages usually preclude such patients from intensive treatment. Many targeted-therapies failed to show a significant survival benefit in AGC, but have regained attention after the positive result of ramucirumab was announced last year. Among all targeted agents, only trastuzumab, a monoclonal antibody against Human epidermal growth factor receptor-2 (HER2) protein, has been proven as having survival benefit by addition to first-line chemotherapy. Herein we reported a patient who benefited from adding trastuzumab to the same second-line combination chemotherapy (paclitaxel, 5-fluorouracil, and leucovorin) upon progression of bulky liver metastases. At least five months of progression-free survival were achieved without any additional toxicity. We also reviewed literature of molecularly-targeted therapy for chemotherapy-refractory gastric cancer, including several large phase III trials (REGARD, GRANITE-1, EXPAND, and REAL-3) published in 2013-2014.

    2016-06-01

    Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy has emerged as one of the primary modalities of treatment of diffuse peritoneal malignancies. It is a complex surgical procedure with the patients facing major and potentially life threatening alterations of haemodynamic, respiratory, metabolic and thermal balance with significant fluid losses and the perioperative management is challenging for anaesthesiologists and intensive care physicians. Though the alterations are short lived, these patients require advanced organ function monitoring and support perioperatively. The anaesthesiologist is involved in the management of haemodynamics, respiratory function, coagulation, haematologic parameters, fluid balance, thermal variations, and metabolic and nutritional support perioperatively. The chemotherapy instillate used are known to cause nephrotoxicity, cardiotoxicity, dyselectrolytemia and lactic acidosis. The preoperative polypharmacy for pain control, previous surgery and/or chemotherapy, malnourished status secondary to feeding problems and tumour wasting syndrome make the task all the more challenging. The anaesthesiologist also needs to consider the perioperative care from a quality of life perspective and proper preoperative counselling is important. The present overview summarizes the challenges faced by the anaesthesiologist regarding the pathophysiological alterations during the Cytoreductive surgery and Hyperthermic intraperitoneal chemotherapy in the preoperative, intraoperative and postoperative periods.

    The management of locally advanced unresectable head and neck squamous cell cancer (HNSCC) continues to improve. One of the major advances in the treatment of HNSCC was the addition of chemotherapy to radiation in the treatment of non-surgical patients. The majority of the data regarding chemotherapy in HNSCC involve cisplatin chemotherapy with concurrent radiation. However, several new approaches have included targeted therapy against epidermal growth factor receptor and several recent studies have explored the role of induction chemotherapy in the treatment of HNSCC. The purpose of this article is to provide an overview of the role of chemotherapy in the treatment of locally advanced HNSCC. PMID:25493232

    Since preoperative chemotherapy has been clearly shown to improve outcomes for patients with Ewing sarcoma, rhabdomyosarcoma, and osteosarcoma, practitioners have attempted to extend the use of adjuvant/neoadjuvant chemotherapy to other types of adult soft tissue sarcoma. Given the high risk of distant recurrence and disease-specific death for patients with soft tissue sarcoma tumors larger than 10 cm, these patients should be considered candidates for neoadjuvant chemotherapy as well as investigational therapies. Yet, potential toxicity from cytotoxic chemotherapy is substantial, and there remains little consensus and wide variation regarding the indications for use of chemotherapy in the adjuvant/neoadjuvant setting.

    Rivkees, S.A.; Crawford, J.D.

    1988-04-08

    The authors tested the hypothesis that chemotherapy-induced gonadal damage is proportional to the degree of gonadal activity during treatment. Thirty studies that evaluated gonadal function after cyclophosphamide therapy for renal disease or combination chemotherapy for Hodgkin's disease or acute lymphocytic leukemia provided data for analysis. Data were stratified according to sex, illness, chemotherapeutic regimen and dose, and pubertal stage at the time of treatment. Chemotherapy-induced damage was more likely to occur in patients who were treated when sexually mature compared with those who were treated when prepubertal. Males were significantly more frequently affected than females when treated for renal disease of Hodgkin's disease. Chemotherapy-induced damage was also more likely to occur when patients were treated with large doses of alkylating agents. These data suggest that chemotherapy-induced damage is proportional to gonadal activity. Further efforts are needed to test whether induced gonadal quiescence during chemotherapy will reduce the strikingly high incidence of gonadal failure following chemotherapy.

    Mortality in breast cancer has declined in the past decade, owing to advances in diagnosis, surgery, radiotherapy, and systemic treatments. Adjuvant chemotherapy has had a major effect on increasing survival in women with locoregional breast cancer. Like all treatments, adjuvant chemotherapy is a work in progress, and it has evolved from single oral agents to complex multidrug regimens. The choice of regimens is not without controversy, however, and several have been shown to be more effective than others, especially in patients who are at high risk for recurrence. The taxanes paclitaxel and docetaxel (Taxotere) have been shown to be effective in the adjuvant setting, and they have also been shown to improve the outcomes in node-positive disease. Both disease-free and overall survival are greater with doxorubicin, paclitaxel, and cyclophosphamide given in a dose-dense, every-2-week schedule with growth factor support than with the same agents given in an every-3-week schedule. Disease-free and overall survival in patients with node-positive disease are greater with docetaxel, doxorubicin (Adriamycin), and cyclophosphamide (TAC) than with fluorouracil, doxorubicin, and cyclophosphamide (FAC). Febrile neutropenia is common with the TAC regimen, but it can be minimized with growth factor support. Based on these findings, dose-dense therapy and TAC are the current adjuvant treatments of choice in patients with node-positive disease; other, less-intense regimens may be appropriate in patients with lower-risk disease. Ongoing trials are investigating the efficacy of commonly used regimens, new chemotherapeutic and biologic agents, and novel doses and schedules of currently available agents. PMID:16506631

    Background Most women with advanced epithelial ovarian cancer will ultimately develop recurrent disease after completion of initial treatment with primary surgery and adjuvant chemotherapy. Secondary cytoreductive surgery may have survival benefits in selected patients. However, a number of chemotherapeutic agents are active in recurrent ovarian cancer and the standard treatment of patients with recurrent ovarian cancer remains poorly defined. Objectives To evaluate the effectiveness and safety of secondary surgical cytoreduction and chemotherapy compared to chemotherapy alone for women with recurrent epithelial ovarian cancer. Search methods We searched the Cochrane Gynaecological Cancer Group Trials Register, The Cochrane Register of Controlled Trials, (CENTRAL) Issue 1 2009, MEDLINE and EMBASE up to February 2009. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of review articles and contacted experts in the field. Selection criteria We searched for RCTs, quasi-randomised trials and non-randomised studies that compared secondary cytoreductive surgery and chemotherapy to chemotherapy alone in women with recurrent epithelial ovarian cancer. Data collection and analysis Three reviewers independently assessed whether potentially relevant studies met the inclusion criteria. No trials were found and therefore no data were analysed. Main results The search strategy identified 1431 unique references of which all were excluded on the basis of title and abstract. Authors’ conclusions We found no evidence from RCTs to inform decisions about secondary surgical cytoreduction and chemotherapy compared to chemotherapy alone for women with recurrent epithelial ovarian cancer. Ideally, a large randomised controlled trial or, at the very least, well designed non-randomised studies that use multivariate analysis to adjust for baseline imbalances are needed to compare these treatment modalities.

    Because of the heterogeneity in the definition of chemotherapy-induced amenorrhea (CIA) there are distinct differences in the literature with regard to its incidence as well as its dependence on various influencing factors. The occurrence of CIA varies greatly depending on the applied chemotherapy. The pathogenesis of CIA is especially based on a reduction of ovarian reserves. Various sonographic and biochemical factors can be used to exclude or confirm CIA. This is particularly important when an endocrine therapy with tamoxifen is not possible and the use of aromatase inhibitors is under consideration. CIA and especially the frequently thereby resulting early menopause can lead to pronounced restrictions in the quality of life of the affected patients, not least due to the resulting infertility. On the other hand, various studies have shown that CIA may have a positive prognostic significance. Thus, the identification of measures to prevent CIA (for example, through the use of GnRH analogues) is of particular importance. PMID:26640289

    Chemotherapy-induced peripheral neuropathy (CIPN) is a toxic neuropathy, a syndrome consisting of highly distressing symptoms of various degrees of severity. It includes numbness of distal extremities, long-term touch, heat, and cold dysaesthesia and, in more severe cases, motor impairment affecting daily functioning. Each form of the syndrome may be accompanied by symptoms of neuropathic stinging, burning, and tingling pain. In the case of most chemotherapeutic agents, the incidence and severity of CIPN are dependent on the cumulative dose of the drug. The syndrome described is caused by damage to the axons and/or cells of the peripheral nervous system. Chemotherapeutic agents have distinct mechanisms of action in both neoplastic tissue and the peripheral nervous system; therefore, CIPN should not be regarded as a homogeneous disease entity. The present article is an attempt to systematize the knowledge about the toxic effects of chemotherapy on the peripheral nervous system. PMID:23788859
