    The surgical treatment of localized breast cancer has become progressively less aggressive over the years. The management of the axillary lymph nodes has been modified by the introduction of sentinel lymph node biopsy. Axillary dissection can be avoided in patients with sentinel lymph node negative biopsies. Based on randomized trials data, it has been proposed that no lymph node dissection should be carried out even in certain patients with sentinel lymph node positive biopsies. This commentary discusses the basis of such recommendations and cautions against a general omission of lymph node dissection in breast cancer patients with positive sentinel lymph node biopsies. Instead, an individualized approach based on axillary tumor burden and biology of the cancer should be considered. PMID:25667909

  3. Women with Breast Cancer Micrometastases in Their Sentinel Lymph Nodes May Not Need Axillary Dissection

    Sparganosis of the breast is an uncommon disease, but should be considered in the differential diagnosis of unusual and suspicious breast masses. A history of ingesting contaminated water and direct ingestion of snakes and frogs may help in differential diagnosis of the mass. Complete surgical removal is the treatment of choice and provides a definite diagnosis. We report a case of multiple axillary lymph node sparganosis. It was first considered as an axillary metastasis of breast cancer because a newly axillary mass appeared in follow-up radiologic study after neoadjuvant chemotherapy. We performed curative breast cancer surgery and sparganosis was confirmed by extracting the worm during axillary dissection. PMID:25485243

    In the sentinel lymph node era, axillary lymph node dissection (ALND) for uninvolved axillary lymph nodes should be considered unnecessary and inappropriate. Between January 2000 and August 2005, 3487 out of 10,031 invasive breast cancer patients consecutively operated at the European Institute of Oncology were considered not suitable for sentinel lymph node biopsy (SNB) and were directly submitted to ALND

    Background and Objective: The study was conducted to detect occult metastases in lymph node negative breast cancer patients using cytokeratin (CK) and epithelial membrane antigen (EMA) immunohistochemistry (IHC) and correlate this with primary tumor size and grade. Materials and Methods: A total of 32 cases including 12 prospective and 20 retrospective cases of axillary lymph node negative breast cancer were studied. CK and EMA IHC were performed to detect micrometastases. Results: Axillary lymph node metastases were detected in 18.75% of previously node negative cases using CK and EMA IHC. CK was found to be more sensitive for detection of metastases compared to EMA. A highly significant correlation was observed between tumor grade and axillary lymph node metastases detected by CK and EMA. However, no significant correlation was found between tumor size and axillary lymph node metastases detected by IHC. Conclusion: In the present study, there was an increase of 18.75% in the occult metastases detection rate using CK and EMA. To conclude, IHC detection of occult metastases should be done using CK in all axillary node negative cases, especially in T1 and T2 stage tumors.

    Axillary lymph node status is a major prognostic factor in mammary carcinoma. It is clinically desirable to predict the axillary lymph node status from data from the mammary cancer specimen. In the study, the axillary lymph node status, routine histological parameters and flow-cytometric data were retrospectively obtained from 1139 specimens of invasive mammary cancer. The ten variables: age, tumour type, tumour grade, tumour size, skin infiltration, lymphangiosis carcinomatosa, pT4 category, percentage of tumour cells in G2/M- and S-phases of the cell cycle, and ploidy index were considered as predictor variables, and the single variable lymph node metastasis pN (0 for pN0, or 1 for pN1 or pN2) was used as an output variable. A stepwise logistic regression analysis, with the axillary lymph node as a dependent variable, was used for feature selection. Only lymphangiosis carcinomatosa and tumour size proved to be significant as independent predictor variables; the other variables were non-contributory. Three paradigms with supervised learning rules (multilayer perceptron, learning vector quantisation and support vector machines) were used for the purpose of prediction. If any of these paradigms was used with the information from all ten input variables, 73% of cases could be correctly predicted, with specificity ranging from 82 to 84% and sensitivity ranging from 60 to 63%. If only the two significant input variables were used, lymphangiosis carcinomatosa and tumour diameter, the prediction accuracy was no worse. Nearly identical results were obtained by two different techniques of cross-validation (leave-one-out against ten-fold cross validation). It was concluded that: artificial neural networks can be used for risk stratification on the basis of routine data in individual cases of mammary cancer; and lymphangiosis carcinomatosa and tumour size are independent predictors of axillary lymph node metastasis in mammary cancer.

    This study aimed to provide additional anatomical information for axillary lymph node dissection (ALND) through in vivo anatomy studies of intercostobrachial nerve (ICBN) preservation in order to provide theoretical and practical experience for clinicians. A total of 156 patients with breast cancer underwent ALND at the Department of Gynecology of Baotou Tumor Hospital between June 2009 and March 2010. The origin, destination, main source, length, branch type, and direction of ICBN in axilla were observed, as well as its relationship with adjacent major blood vessels and nerves within the axilla. There were 120 cases of single trunk, 23 cases of double trunks, 9 cases of multiple trunks, and 4 cases without trunks in 156 patients with ICBN preservation. The transverse diameter at the origin of the ICBN was 1.89 ± 0.44 mm with a length of 94.45 ± 12.08 mm; the distances were 77.19 ± 21.04 mm, 29.34 ± 6.73 mm, 90.04 ± 13.13 mm, and 28.63 ± 13.01 mm from origin to the inferior margin at the midpoint of the clavicle, inferior margin of the axillary vein, the bottom of axilla, and branch point, respectively. The identification, dissection, and preservation of ICBN was simple and easy in a modified radical mastectomy for breast cancer and breast-conserving surgery, which only took 10-20 min, but effectively reduced the incidence of post-mastectomy pain syndrome and significantly improved the quality of life for patients after surgery.

    Spontaneous regression (SR) of cancer is a rare but well-documented biological phenomenon. However, the mechanism remains to be elucidated. We herein report a case of the SR of breast cancer at both the primary site and metastatic axillary lymph node with spontaneously-induced T cell-mediated immunological responses. A 52-year-old female with a lump in the left axilla was diagnosed to have a small breast carcinoma with a distinct axillary lymph node metastasis. During the preoperative systemic examination, she was diagnosed to have severe type 2 diabetes mellitus, was treated with insulin, and the hyperglycemia was normalized after one month. Surgery for left breast cancer was then performed. The postoperative histopathological examination revealed the SR of breast cancer at both the primary site and metastatic axillary lymph node. Immunohistochemical studies revealed that estrogen receptor positive, AE1/AE3-positive ductal carcinoma completely underwent necrosis associated with extensive infiltration of CD3-positive T cells in the tumor nodule in the lymph node. In addition, primary ductal carcinoma cells also underwent single cell necrosis with infiltration of T cells with lymph follicle-like organization of B cells in the mammary gland. The features were suggestive that the tumor eradication in the metastatic lymph node and regression of the primary ductal carcinoma could be due to host T cell response to the ductal carcinoma. As far as we know it is the first report that shows the spontaneous regression of breast cancer, probably due to the spontaneously-induced T cell response. PMID:25120822

  12. Morbidity after conventional dissection of axillary lymph nodes in breast cancer patients

    PubMed Central

    2014-01-01

    Background Conventional axillary lymph node dissection (ALND) has recently become less radical. The treatment morbidity effects of reduced ALND aggressiveness are unknown. This article investigates the prevalence of the main complications of ALND: lymphedema, range-of-motion restriction, and arm paresthesia and pain. Methods This cross-sectional study included 200 women with invasive breast cancer who underwent breast-conserving surgery (82.5%, n?=?165) or mastectomy (17.5%, n?=?35) with ALND from 2007 to 2011. Arm perimetry was used to assess lymphedema, defined as a difference >2 cm in the upper arm circumference between the nonsurgical and surgical arms. Range-of-motion restriction was assessed by evaluating the degree of arm abduction. Paresthesia was measured in the inner and proximal arm regions. Arm pain was assessed by directly questioning the patients and defined as either present or absent. Results The average (±SD) time between ALND and morbidity evaluation was 35?±?18 months (range, 7-60 months). The average dissected lymph node number per patient was 14?±?4 (range, 6-30 lymph nodes). Only 3.5% (n?=?7) of the patients presented with lymphedema. Single-incision approaches to breast tumor and ALND (P?=?0.04) and the presence of a postoperative seroma (P?=?0.02) were associated with lymphedema in univariate analysis. Paresthesia was the most frequent side effect observed (53% of patients, n?=?106). This complication was associated with increased age (P?lymph node number (P?=?0.01) in univariate and multivariate analysis. Additionally, 24% (n?=?48) of patients had noticeable limited arm abduction. Among the patients, 27.5% (n?=?55) experienced sporadic arm pain corresponding to the surgically treated armpit. In multivariate analysis, the pain risk was 1.9-fold higher in patients who underwent ALND corresponding to their dominant arm (95% CI, 1.0-3.7, P?=?0.04). Conclusion Conventional ALND in breast cancer patients can result in unwanted complications. However, the current lymphedema prevalence is lower than that of the other analyzed side effects.

    BACKGROUND The axillary pathologic complete response rate (pCR) and the effect of axillary pCR on disease-free survival (DFS) was determined in patients with HER2-positive breast cancer and biopsy-proven axillary lymph node metastases who were receiving concurrent trastuzumab and neoadjuvant chemotherapy. The use of neoadjuvant chemotherapy is reported to result in pCR in the breast and axilla in up to 25% of patients. Patients achieving a pCR have improved DFS and overall survival. To the authors’ knowledge, the rate of eradication of biopsy-proven axillary lymph node metastases with trastuzumab-containing neoadjuvant chemotherapy regimens has not been previously reported. METHODS Records were reviewed of 109 consecutive patients with HER2-positive breast cancer and axillary metastases confirmed by ultrasound-guided fine-needle aspiration biopsy who received trastuzumab-containing neoadjuvant chemotherapy followed by breast surgery with complete axillary lymph node dissection. Survival was evaluated by the Kaplan-Meier method. Clinicopathologic factors and DFS were compared between patients with and without axillary pCR. RESULTS Eighty-one patients (74%) achieved a pCR in the axilla. Axillary pCR was not associated with age, estrogen receptor status, grade, tumor size, initial N classification, or median number of lymph nodes removed. More patients with an axillary pCR also achieved a pCR in the breast (78% vs 25%; P < .001). At a median follow-up of 29.1 months, DFS was significantly greater in the axillary pCR group (P = .02). CONCLUSIONS Trastuzumab-containing neoadjuvant chemotherapy appears to be effective in eradicating axillary lymph node metastases in the majority of patients treated. Patients who achieve an axillary pCR are reported to have improved DFS. The success of pCR with concurrent trastuzumab and chemotherapy in eradicating lymph node metastases has impli cations for surgical management of the axilla in these patients. PMID:20564395

    Quantitative photoacoustics is emerging as a new hybrid modality to investigate diseases and cells in human pathology and cytology studies. Optical absorption of light is the predominant mechanism behind the photoacoustic effect. Therefore, a need exits to characterize the optical properties of specimens and to identify the relevant operating wavelengths for photoacoustic imaging. We have developed a custom low-cost spectrophotometer to measure the optical properties of human axillary lymph nodes dissected for breast-cancer staging. Optical extinction curves of positive and negative nodes were determined in the spectral range of 400 to 1000 nm. We have developed a model to estimate tissue optical properties, taking into account the role of fat and saline. Our results enabled us to select the optimal optical wavelengths for maximizing the imaging contrast between metastatic and noncancerous tissue in axillary lymph nodes.

    Sentinel lymph node (SLN) biopsy is now standard practice in the management of many breast cancer patients. Localization protocols vary in complexity and rates of success. The least complex involve only intraoperative gamma counting of radiotracer uptake or intraoperative visualization of blue-dye uptake; the most complex involve preoperative gamma imaging, intraoperative counting and intraoperative dye visualization. Intraoperative gamma imaging may improve some protocols. This study was conducted to obtain preliminary experience and information regarding intraoperative imaging. Sixteen patients were enrolled: 8 in a protocol that included intraoperative counting and dye visualization (probe/dye), 8 in a protocol that involved intraoperative imaging, counting and dye visualization (camera/probe/dye). Preoperative imaging of all 16 patients was performed using a GE 500 gamma camera with a LEAP collimator (300 cpm/muCi). The results of this imaging were not, however, given to the surgeon until the surgeon had completed the procedures required for the study. A Care Wise C-Trak probe was used for intraoperative counting. A Gamma Medica Inc. GammaCAM/OR (12.5 x 12.5 cm FOV) with a LEHR collimator (135 cpm/muCi) was used for intraoperative imaging. Times from start of surgery to external detection of a radioactive focus and to completion of excision of SLNs were recorded. Foci were detected preoperatively via imaging in 16/16 patients. Intraoperative external detection using the probe was accomplished in less than 4 min (mean = 1.5 min) in 15/16 patients, and via intraoperative imaging in 6/8 patients. The average time for completion of excision of nodes was 19 min for probe/dye and 28 min for camera/probe/dye. In one probe/dye case, review of the preoperative images prompted the surgeon to resume axillary dissection and remove one additional SLN. PMID:17646000

    Objective To assess the significance of axillary lymph node status and tumor size for predicting locoregional recurrence (LRR) and overall survival after mastectomy for breast cancer and to discuss the utility of postmastectomy radiation therapy. Summary Background Data Patients with locally advanced breast cancer require multimodality treatment combining chemotherapy (and/or hormonal therapy), surgery, and radiation. Randomized trials have demonstrated that postmastectomy radiation reduces LRR, but no overall survival benefit has been established. Methods Criteria for accrual to the Alabama Breast Cancer Project (1975–1978) were female gender and T2–3 breast cancer with M0 status. Patients underwent a radical or a modified radical mastectomy. Node-positive patients received adjuvant cyclophosphamide, methotrexate, and fluorouracil chemotherapy or adjuvant melphalan. Patients were evaluated for LRR and overall survival based on the number of positive axillary lymph nodes and (in N0 patients) pathologic tumor size. Significance was determined using chi-square analysis. Survival curves were generated using the Kaplan-Meier method and were compared by log-rank analysis. Results After median follow-up of 15 years, neither type of surgery nor chemotherapy was shown to affect locoregional disease-free or overall survival. LRR rates were higher and overall survival rates were lower in patients with nodal involvement, while tumor size was not shown to significantly affect these rates. Conclusions Patients with axillary lymph node metastases may benefit from postmastectomy radiation, but the use of postmastectomy radiation in N0 patients is not supported when it is based on tumor size alone.

    To determine the performance of intraoperative one-step nucleic acid amplification (OSNA) assay in detecting sentinel lymph node metastases compared to postoperative histology taking into account breast cancer molecular classification and to evaluate whether the level of cytokeratin 19 mRNA copy number may be useful in predicting the likelihood of a positive axillary lymph node dissection. OSNA assay was performed in a prospective series of 903 consecutive sentinel lymph nodes from 709 breast cancer patients using 2 alternate slices of each sentinel lymph node. The remaining 2 slices were investigated by histology. Cytokeratin 19 mRNA copy number, which distinguishes negative cases (<250 copies), micrometastases (+, ?250?5000 copies) and macrometastases (++, >5000 copies), was compared to axillary lymph node dissection status and to the biological tumor profile. Concordance between OSNA and histopathology was 95%, specificity 95% and sensitivity 93%. Multiple Corresponce Analysis and logistic regression evidenced that positive axillary lymph node dissection was significantly associated with a higher cytokeratin 19 mRNA copy number (>5000; p<0.0001), HER2 subtype (p?=?0.007) and lymphovascular invasion (p<0.0001). Conversely, breast cancer patients with cytokeratin 19 mRNA copy number <2000 mostly presented a luminal subtype and a negative axillary lymph node dissection. We confirmed that OSNA assay can provide standardized and reproducible results and that it represents a fast and quantitative tool for intraoperative evaluation of sentinel lymph node. Omission of axillary lymph node dissection could be proposed in patients presenting a sentinel lymph node with a cytokeratin 19 mRNA copy number <2000 and a Luminal tumor phenotype. PMID:23533593

    The aim of this study is construction of a pathologic nomogram that can predict axillary lymph node metastasis (LNM) for each intrinsic subtype of breast cancer with regard to histologic characteristics in breast core needle biopsy (CNB) for use in routine practice. A total of 534 CNBs with invasive ductal carcinoma classified into 5 intrinsic subtypes were enrolled. Eighteen clinicopathological characteristics and 8 molecular markers used in CNB were evaluated for construction of the best predictive model of LNM. In addition to conventional parameters including tumor multiplicity (P < .001), tumor size (P < .001), high histologic grade (P = .035), and lymphatic invasion (P = .017), micropapillary structure (P < .001), the presence of small cell-like crush artifact (P = .001), and overexpression of HER2 (P = .090) and p53 (P = .087) were proven to be independent predictive factors for LNM. A combination of 8 statistically independent parameters yielded the strongest predictive performance with an area under the curve of 0.760 for LNM. A combination of 6 independent variables, including tumor number, tumor size, histologic grade, lymphatic invasion, micropapillary structure, and small cell-like crush artifact produced the best predictive performance for LNM in luminal A intrinsic subtype (area under the curve, 0.791). Thus, adding these combinations of clinical and morphologic parameters in preoperative CNB is expected to enhance the accuracy of prediction of LNM in breast cancer, which might serve as another valuable tool in determining optimal surgical strategies for breast cancer patients.

    The aim of the present study is to look at the mitotic activity index (MAI) as a prognostic factor in a prospective population-based cohort of lymph node-negative invasive breast cancer patients. Analyses were based on 2,048 breast-conserving therapies in 1,971 patients, node-negative, and without any form of adjuvant systemic therapy with long-term follow-up. The 15-year distant metastases-free survival (DMFS) for women ?55 years was 88.3 % for low MAI values (?12) versus 73.4 % for high MAI values (>12); (HR 2.8; 95 % CI 1.8-4.4; p < 0.001). Multivariate analyses for DMFS showed significance for MAI. For MAI and Bloom-Richardson grading, by performing a likelihood ratio test, we showed the statistical significance for both. For women >55-years, the MAI was not an independent significant factor. We also confirmed the above findings for disease-specific survival. When multi-gene assays are not available, the MAI remains a robust prognostic marker in women younger than 55 years of age with early node-negative breast cancer. PMID:25526926

    The purpose of this study was to assess the usefulness of HER2 levels in ultrasonographically guided fine-needle aspiration biopsy (US-FNA) aspirates of axillary lymph nodes (ALNs) in the determination of lymph node metastasis or the characterization of primary breast cancer, and to correlate the HER2 levels in US-FNA aspirates (FNA-HER2s) of metastatic ALNs with the HER2 statuses of corresponding primary breast cancers. An institutional review board approved the study. Between January and October 2010, 164 patients with 167 ALNs examined by US-FNA were included. FNA-HER2s of ALNs were measured by chemiluminescence immunoassay, and they were correlated with cytologic/final diagnoses. Receiver operating characteristics (ROC) curve analysis was performed to evaluate the diagnostic ability to differentiate benign and metastatic ALNs. Additionally, FNA-HER2s of metastatic ALNs were correlated with HER2 status and other clinicopathologic variables of the primary breast cancers. Among the 167 ALNs, 138 were metastatic and 29 were benign. The mean FNA-HER2 (6.3 ng/ml) of metastatic ALNs was higher than that of benign ALNs. All 29 benign ALNs showed no measurable value of FNA-HER2 (0.0 ng/ml). The area under the ROC curves of FNA-HER2 of ALNs was 0.679 for the diagnosis of ALN metastasis. The FNA-HER2 statuses of 108 metastatic ALNs (79.4%) were concordant with the HER2 statuses of the corresponding primary breast cancers. In a subgroup analysis of HER2-positive cancers with ALN metastasis, distant metastasis was significantly associated with FNA-HER2-negativity of metastatic ALNs (P?=?0.04). Although FNA-HER2 of ALNs did not improve the diagnostic performance of FNA cytology in preoperative diagnosis of ALN metastasis of overall patients, FNA-HER2-positive metastatic ALNs were significantly associated with HER2-positivity of primary breast cancers. Additionally, FNA-HER2 analysis of ALN may help to develop more personalized treatment protocol for breast cancer patients by determining the concordance or discordance of HER2 status between primary cancers and metastatic ALNs.

    Background Breast cancer patients’ quality of life (QoL) after surgery has been reported to improve significantly over time. Little is known about QoL recovery after sentinel lymph node biopsy (SLNB) in comparison to axillary lymph node dissection (ALND). Methods 175 of 195 stage I/II breast cancer patients completed the EORTC QLQ-C30: one day before surgery (T0) and after 6 (T1), 26 (T2), 52 (T3) and 104 (T4) weeks. Of these, 54 patients underwent SLNB, 56 SLNB+ALND and 65 ALND. General linear models and paired T-tests between T0–T4 and T1–T4 were computed. Complications, radiotherapy and systemic therapy were added to the model. Results Significant time effects were found on physical, role and emotional functioning. Physical and role functioning decreased between T0 and T1. At T4, SLNB patients’ functioning had increased to their T0 level; ALND (+/– SLNB) patients’ functioning had increased, but had not improved to T0 level. Emotional functioning increased linearly between T0 and T4. At T4, emotional functioning was significantly higher in all groups as compared with T0. No significant group or interaction (time × group) effects were found. Complications and chemotherapy had a significant negative effect on role, emotional and cognitive functioning. Complications had a significant effect on social functioning also. Effect sizes varied between 0.00 and 0.06. Conclusion Two years post surgery, breast cancer patients’ QoL is comparable to that shortly before surgery. Women rated their emotional functioning as even better. SLNB is not associated with a better QoL than ALND. However, undergoing systemic therapy and/or experiencing complications affects QoL negatively. PMID:18597146

    Use of sentinel lymph node dissection in patients with ipsilateral breast cancer recurrence is still controversial. The objective of this study is to evaluate the feasibility of the sentinel lymph node in breast cancer recurrence (SLNBR) and whether the positivity had impact in the adjuvant treatment. Between 2008 and 2012 we performed SLNBR in patients with ipsilateral breast tumor recurrence. We included 53 patients in a prospective study. Forty-three patients (81%) had a previous axillary lymph node dissection (ALND) and ten (19%) had a previous sentinel lymph node biopsy (SLNB). Identification rate after SLNB was 50% and after ALND was 60.5% (p = 0.4). Nine patients (26%) had a positive SLNBR. Adjuvant systemic treatment was given to all the patients with a positive SLNBR and to 23 (85%) with a negative SLNBR (p = 0.29). Six patients (66%) with positive SLNBR and 4 patients (14%) with negative SLNBR underwent radiation therapy (p < 0.01). As conclusions of our study we conclude that sentinel lymph node biopsy in breast tumor recurrence is feasible and significant differences were found in the use of radiation therapy in patients with a positive SLNBR.

    Purpose This study compared the survival outcomes of different treatment methods for the ipsilateral breast of occult breast cancer (OBC) patients with axillary lymph node metastasis. Methods A retrospective study was conducted in which forty OBC patients with axillary lymph node metastasis were identified out of 15,029 patients who had been diagnosed with a primary breast cancer at between 1992 and 2010. The patients were categorized into three treatment groups based on ipsilateral breast management: breast-conserving surgery (BCS) (n=17), mastectomy (n=12), and nonsurgical intervention with or without radiation therapy (No surgery with or without radiation therapy [No Op±RT]) (n=11). All patients underwent axillary lymph node dissection. Cases were evaluated based on treatment and potential prognostic factors with respect to overall survival (OS) and disease-free survival (DFS). Results During the follow-up period (median follow-up of 71.5 months), the overall OS and DFS were 76.9% and 74.9%, respectively. The 5-year treatment-specific OS was 72.0% for the BCS group, 74.0% for the mastectomy group, and 87.5% for the No Op±RT group (log-rank p=0.49). The 5-year DFS was 70.6% for the BCS group, 66.7% for the mastectomy group, and 90.9% for the No Op±RT group (log-rank p=0.36). Recurrence rates for the BCS and No Op±RT groups were 5.9% and 18.2%, respectively. Histologic grade and lymph node status were inversely correlated with DFS (log-rank p=0.04 and p<0.01, respectively). Conclusion There was no difference in survival outcomes between the three treatment methods for the ipsilateral breast (mastectomy, BCS, and No Op±RT) of OBC patients with axillary lymph node metastasis. A large-scale multicenter study is needed to validate the results from this small retrospective study. PMID:24454463

    Purpose: To analyze tumor control and survival for breast cancer patients with 10 or more positive lymph nodes without systemic disease, treated by adjuvant radiation alone or combined-modality therapy. Methods and Materials: We reviewed the records of 309 consecutive patients with these characteristics who received locoregional radiotherapy (RT) at our institution. The majority of patients had clinical Stage II or IIIA-B disease (43% and 48%, respectively). The median number of positive axillary lymph nodes was 15 (range, 10-78). Adjuvant therapy consisted of RT alone, with or without chemotherapy, tamoxifen, and/or ovarian castration. Results: The overall 5-year and 10-year disease-free survival (DFS) rates were 20% and 7%, respectively. Median DFS was higher for patients with Stage I-II compared with those with Stage IIIABC (28 vs. 19 months; p = 0.006). Median DFS for patients aged {<=}35 years was lower than that of older patients (12 vs. 24 months; p < 0.0001). Patients treated with a combination therapy had a higher 5-year DFS rate compared with those treated by RT alone (26% vs. 11%; p 0.03). In multivariate analysis, clinical stage (III vs. I, II; relative risk = 1.8, p = 0.002) and age ({<=}35 vs. others; relative risk = 2.6, p <0.001) were found to be independent variables for DFS. Conclusion: This retrospective data analysis identified young age and advanced clinical stage as pertinent and independent clinical prognostic factors for breast cancer patients with advanced axillary disease (10 or more involved nodes). These factors can be used for further prognostic classification.

    In this proof-of-concept study we seek to demonstrate the delivery of fluorescent contrast agent to the tumor-draining lymph node basin following intraparenchymal breast injections and intradermal arm injection of micrograms of indocyanine green in 20 breast cancer patients undergoing complete axillary lymph node dissection. Individual lymph nodes were assessed ex vivo for presence of fluorescent signal. In all, 88% of tumor-negative lymph nodes and 81% of tumor-positive lymph nodes were fluorescent. These results indicate that future studies utilizing targeted fluorescent contrast agents may demonstrate improved surgical and therapeutic intervention.

    Usefulness of MUC1 mRNA and keratin 19 mRNA as a target of reverse-transcriptase polymerase chain reaction (RT-PCR) was compared in the detection of breast cancer micrometastases in axillary lymph nodes. RT-PCR amplification of MUC1 mRNA and keratin 19 mRNA was conducted using total RNA samples. RT-PCR products were stained with ethidium bromide and analyzed by agarose gel electrophoresis. Expression of both MUC1 mRNA and keratin 19 mRNA was detected by RT-PCR in a breast cancer cell line (MRK) and in all the 23 primary breast cancers but not in the control lymph nodes obtained from patients with benign diseases. A serial dilution study of MRK cells against normal lymph node cells has shown that detection sensitivity of MUC1 RT-PCR and keratin 19 RT-PCR were 1/10(5) and 1/10(6) (cancer/lymph node cells), respectively. Sixty-three axillary lymph nodes were obtained from 23 patients with primary breast cancer, and metastases in each lymph node were investigated by histological examination (hematoxylin and eosin sections) and RT-PCR method. In all 10 lymph nodes, which were histologically metastasis-positive, both MUC1 mRNA and keratin mRNA were detected by RT-PCR. Of the 53 histologically negative lymph nodes, 3 (6%) and 5 (9%) lymph nodes were found to express MUC1 mRNA and keratin 19 mRNA, respectively, indicating the presence of micrometastases which could be detected by RT-PCR but not by histological examination. These results demonstrate the usefulness of both MUC1 RT-PCR and keratin 19 RT-PCR in the detection of breast cancer micrometastases in lymph nodes, and also indicate the superiority of keratin 19 RT-PCR over MUC1 RT-PCR because of its higher detection sensitivity.

    Pathological aspects of axillary nodal staging of breast cancer and in particular sentinel lymph node (SLN) biopsy are reviewed. SLN biopsy seems an almost ideal staging procedure because it has both high accuracy and a low false negative rate. It may also allow a cost effective use of more sensitive methods of metastasis detection. However, the biological relevance of metastases detected only by modern tools remains to be elucidated. This review focuses on standard axillary staging and the histopathological investigation of SLNs, with emphasis on the intraoperative setting. Future trends including ancillary studies, quality control issues, prediction of non-SLN involvement, and suggestions concerning the minimum requirements for the histology of axillary SLNs are also discussed.

    Background: Our objective was to assess the global cost of the sentinel lymph node detection [axillary sentinel lymph node detection (ASLND)] compared with standard axillary lymphadenectomy [axillary lymph node dissection (ALND)] for early breast cancer patients. Patients and methods: We conducted a prospective, multi-institutional, observational, cost comparative analysis. Cost calculations were realized with the micro-costing method from the diagnosis until 1 month after the last surgery. Results: Eight hundred and thirty nine patients were included in the ASLND group and 146 in the ALND group. The cost generated for a patient with an ASLND, with one preoperative scintigraphy, a combined method for sentinel node detection, an intraoperative pathological analysis without lymphadenectomy, was lower than the cost generated for a patient with lymphadenectomy [€2947 (? = 580) versus €3331 (? = 902); P = 0.0001]. Conclusion: ASLND, involving expensive techniques, was finally less expensive than ALND. The length of hospital stay was the cost driver of these procedures. The current observational study points the heterogeneous practices for this validated and largely diffused technique. Several technical choices have an impact on the cost of ASLND, as intraoperative analysis allowing to reduce rehospitalization rate for secondary lymphadenectomy or preoperative scintigraphy, suggesting possible savings on hospital resources.

    Purpose To investigate the coverage of axillary lymph node with tangential breast irradiation fields by using virtual lymph node (LN) analysis. Materials and Methods Forty-eight women who were treated with whole breast irradiation after breast-conserving surgery were analyzed. The axillary and breast volumes were delineated according to the Radiation Therapy Oncology Group (RTOG) contouring atlas. To generate virtual LN contours, preoperative fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) scans with identifiable LN were fused with the CT scans, and the virtual LN contour were delineated on the CT. Results The median level I and II axillary volume coverage percentages at the VD95% line were 33.5% (range, 5.3% to 90.4%) and 0.6% (range, 0.0% to 14.6%), respectively. Thirty-one LNs in 18 patients were delineated (26 in level I and 5 in level II). In the level I axilla, 84.6% of virtual LNs were encompassed by the 95% isodose line. In the level II axilla, by contrast, none of the virtual LNs were encompassed by the 95% isodose volumes. There was a substantial discrepancy between the RTOG contouring atlas-based axillary volume analysis and the virtual LN analysis, especially for the level I axillary coverage. The axillary volume coverage was associated with the body mass index (BMI) and breast volume. Conclusion The tangential breast irradiation did not deliver adequate therapeutic doses to the axillary region, particularly those in the level II axilla. Patients with small breast volumes or lower BMI showed reduced axillary coverage from the tangential breast fields. For axillary LN irradiation, individualized anatomy-based radiation fields for patients would be necessary.

    The presence of axillary lymph node metastases is the most important prognostic factor in breast cancer and can influence the selection of adjuvant therapy, both chemotherapy and radiotherapy. In this work we present a set of kinetic statistics derived from DCE-MRI for predicting axillary node status. Breast DCE-MRI images from 69 women with known nodal status were analyzed retrospectively under HIPAA and IRB approval. Axillary lymph nodes were positive in 12 patients while 57 patients had no axillary lymph node involvement. Kinetic curves for each pixel were computed and a pixel-wise map of time-to-peak (TTP) was obtained. Pixels were first partitioned according to the similarity of their kinetic behavior, based on TTP values. For every kinetic curve, the following pixel-wise features were computed: peak enhancement (PE), wash-in-slope (WIS), wash-out-slope (WOS). Partition-wise statistics for every feature map were calculated, resulting in a total of 21 kinetic statistic features. ANOVA analysis was done to select features that differ significantly between node positive and node negative women. Using the computed kinetic statistic features a leave-one-out SVM classifier was learned that performs with AUC=0.77 under the ROC curve, outperforming the conventional kinetic measures, including maximum peak enhancement (MPE) and signal enhancement ratio (SER), (AUCs of 0.61 and 0.57 respectively). These findings suggest that our DCE-MRI kinetic statistic features can be used to improve the prediction of axillary node status in breast cancer patients. Such features could ultimately be used as imaging biomarkers to guide personalized treatment choices for women diagnosed with breast cancer.

    Differentiated thyroid cancer is, usually, associated with an excellent prognosis and indolent course. Distant metastases are rare events at the onset of thyroid cancer. Among these presentations, metastasis to the axillary lymph nodes is even more unusual. Only few cases of papillary carcinoma with axillary nodal metastasis were previously reported in the literature. We present a 38-year-old female who underwent Iodine-131 whole-body scintigraphy, after total thyroidectomy and bilateral neck lymph node dissection for papillary carcinoma of thyroid, showed intense uptake in the remnant thyroid, lung metastasis, left cervical and left axillary lymph nodes. Excision of left axillary lymph nodes confirmed metastatic papillary carcinoma.

    BACKGROUND Axillary reverse mapping (ARM) is a novel technique to preserve upper extremity lymphatics that may reduce the incidence of lymphedema after axillary lymph node dissection. Early reports have suggested that ARM lymph nodes do not contain metastatic disease from breast cancer; however, these studies were conducted in early stage patients with low likelihood of lymph node metastasis. This study reported a phase 1 trial conducted in patients with cytologically documented axillary metastasis undergoing axillary lymph node dissection to determine the feasibility and oncologic safety of ARM. METHODS Thirty patients, 23 (77%) of whom received preoperative therapy (chemotherapy in 22 patients and hormonal therapy in 1 patient), were enrolled. Blue dye was injected in the upper inner ipsilateral arm. The presence of blue lymphatics was noted, and blue lymph nodes were sent separately for pathologic evaluation. RESULTS The average time between blue dye injection and axillary exposure was 35 minutes (range, 15–60 minutes). Blue lymphatics were identified in 21 patients (70%) and blue lymph nodes in 15 patients (50%). The median number of ARM lymph nodes was 1 (range, 0–3 lymph nodes) and the median number of axillary lymph nodes was 26 (range, 6–47 lymph nodes). Axillary metastases were noted in 60% (18 of 30) of patients. Of 11 patients who had axillary metastasis and at least 1 ARM lymph node identified, 2 (18%) had metastasis to the ARM lymph node. CONCLUSIONS ARM appears to be a feasible technique with which to identify upper arm lymphatics during axillary surgery. However, the high prevalence of disease involving ARM lymph nodes in this small cohort suggested that preservation of these lymphatics is not oncologically safe in women with documented axillary lymph node metastasis from breast cancer.

    Background Prone breast positioning reduces skin reaction and heart and lung dose, but may also reduce radiation dose to axillary lymph nodes (ALNs). Methods Women with early stage breast cancer treated with whole breast irradiation (WBI) in the prone position were identified. Patients treated in the supine position were matched for treating physician, laterality, and fractionation. Ipsilateral breast, tumor bed, and Level I, II, and III ALNs were contoured according to the RTOG breast atlas. Clips marking surgically removed sentinel lymph nodes (SLN)s were contoured. Treatment plans developed for each patient were retrospectively analyzed. V90% and V95% was calculated for each axillary level. When present, dose to axillary surgical clips was calculated. Results Treatment plans for 46 women (23 prone and 23 supine) were reviewed. The mean V90% and V95% of ALN Level I was significantly lower for patients treated in the prone position (21% and 14%, respectively) than in the supine position (50% and 37%, respectively) (p?axillary Level I. The mean V95% of SLN clips was 47% for patients treated in the supine position and 0% for patients treated in the prone position (p?axillary coverage is indicated such as those with positive sentinel lymph node biopsy who do not undergo completion axillary dissection, treatment in the prone position may be inappropriate.

    To assess the advantages of an optimized posterior axillary (AX) boost technique for the irradiation of supraclavicular (SC) and AX lymph nodes. Five techniques for the treatment of SC and levels I, II, and III AX lymph nodes were evaluated for 10 patients selected at random: a direct anterior field (AP); an anterior to posterior parallel pair (AP-PA); an anterior field with a posterior axillary boost (PAB); an anterior field with an anterior axillary boost (AAB); and an optimized PAB technique (OptPAB). The target coverage, hot spots, irradiated volume, and dose to organs at risk were evaluated and a statistical analysis comparison was performed. The AP technique delivered insufficient dose to the deeper AX nodes. The AP-PA technique produced larger irradiated volumes and higher mean lung doses than the other techniques. The PAB and AAB techniques originated excessive hot spots in most of the cases. The OptPAB technique produced moderate hot spots while maintaining a similar planning target volume (PTV) coverage, irradiated volume, and dose to organs at risk. This optimized technique combines the advantages of the PAB and AP-PA techniques, with moderate hot spots, sufficient target coverage, and adequate sparing of normal tissues. The presented technique is simple, fast, and easy to implement in routine clinical practice and is superior to the techniques historically used for the treatment of SC and AX lymph nodes.

    BACKGROUND: The benefits of sentinel lymph node biopsy (SLNB) for breast cancer patients with histologically negative axillary nodes, in whom axillary lymph node dissection (ALND) is thereby avoided, are now established. Low false negative rate, certainly with blue dye technique, mostly reflects the established high inherent accuracy of SLNB and low axillary nodal metastatic load (subject to patient selection). SLN

    Kikuchi-Fujimoto disease (KFD) or histiocytic necrotising lymphadenitis is a rare entity, occurring most commonly in young Asian adults. KFD is characterised by fever with tender lymph node enlargement. The cervical group of lymph nodes is most commonly involved, and the diagnosis is conclusively made by lymph node biopsy and histopathology. KFD is a self-limiting condition, which usually resolves over 1-4?months. Symptomatic treatment with antipyretics and/or non-steroidal anti-inflammatory drugs is recommended. Here we describe an uncommon presentation of KFD in a young woman in which only the axillary lymph nodes were enlarged. PMID:25564582

    Purpose Neoadjuvant chemotherapy (NAC) has been recently used to downstage breast cancer. However, in patients with initial axillary lymph node (ALN) metastasis, ALN dissection regardless of the NAC response remains the standard treatment. The purpose of this study was to identify the feasibility and accuracy of sentinel lymph node biopsy (SLNB) after NAC in patients with ALN metastasis at diagnosis. Methods From January 2007 to August 2013, data of patients who were diagnosed with invasive breast cancer and ALN metastasis and treated with NAC followed by definitive surgery in two centers were collected retrospectively. A total of 386 patients were enrolled and classified into five groups according to surgical procedure for the ALNs and pathologic results. Results At SLNB after NAC, sentinel lymph nodes (SLNs) that stained blue or were hot, including suspicious nodes, were identified; the SLN identification and false-negative rates was 96% and 10%, respectively. There was no difference in the overall survival among the groups. For patients who revealed a pathologic complete node response, there was a significant difference in the disease-free survival rate between the SLNB only and complete ALN dissection groups (p=0.031). However, the rate of axillary recurrence demonstrated no significant differences among the groups (p>0.050). Conclusion SLNB after NAC in breast cancer patients with initial ALN metastasis may help identify downstaging to negative nodal status and thereby reduce the surgical morbidity by avoiding standard ALN dissection.

    Summary We have reviewed the available clinical data on the benefit of axillary treatment in patients with early breast cancer. The results of these studies suggest that perhaps 5–10% of patients are cured by effective axillary treatment. We conclude that effective axillary treatment should still be considered an essential aspect of primary treatment.

    We report 2 cases of bland, otherwise nondescript axillary lymph node inclusions that have the immunophenotype of endosalpingiosis in patients with concurrent invasive breast carcinomas. Neither inclusion demonstrated the classic morphology of endosalpingiosis with admixed ciliated and secretory cells. Rather, both cases were composed of nondescript cuboidal to columnar bland epithelial cells situated within the lymph node capsule. Whereas both inclusions labeled diffusely for estrogen receptor and lacked evidence of a myoepithelial component, both labeled diffusely for PAX8 and WT-1, which distinguished them from their corresponding concurrent primary mammary carcinomas. These findings suggest that a subset of otherwise nondescript axillary lymph node inclusions represent endosalpingiosis and highlight the utility of PAX8 and WT-1 immunohistochemistry in distinguishing these from metastatic well-differentiated ductal carcinoma.

    The primo vascular system (PVS) floating in lymph fluid has mostly been observed in large caliber ducts around the caudal vena cava and the thoracic duct of rabbits, rats, and mice. But the PVS has not been traced up to the lymph nodes. It has not been established whether the PVS leaves the lymph vessel through the lymph vessel wall or it enters the lymph nodes. Therefore, observing the PVS entering a lymph node, for example, the axillary node, is desirable. In the current work, we traced the PVS approaching up to the surface of axillary node of a rat. The method used for this study was based upon a method that was recently developed to detect the PVS in the lymph duct from the inguinal to the axillary nodes in the skin of a rat by injecting Alcian blue into the inguinal node. However, the Alcian blue blurred near the lymph nodes and tracing the PVS up to the lymph nodes has not been possible. The current method clearly showed the PVS approaching the axillary node.

    A routine measurement with two 200 mm-diameter phoswich detectors, placed one each side of the sternum, yielded an apparent lung content of 17 nCi 241Am for a subject. subject. Inspection of the data revealed that there were many more counts from the left side than from the right and that there was a greater number of Np L X rays observed, relative to the L gamma ray, than would be expected for a uniform lung distribution of 241Am. These observations suggested a shallow localised deposit in the left side of the chest. The subject's working history could not rule out an inhalation exposure, but he was known to have had a wound contaminated with Pu/Am in his left hand 16 yr previously. The wound had contained approx. 0.02-0.03 mu Ci 241Am initially, most of which was excised from the wound site after 50 days. Prompted by this knowledge we used a 50mm-diameter intrinsic Ge detector to examine the wound and relevant lymph node sites. The results demonstrated a localised deposit of 241Am in the axillary lymph nodes with approx. 1 nCi 241Am at the wound site. Subsequent measurements made with the phoswich detectors suggested that there was approx. 7 nCi 241Am in the lymph nodes with approx. 1 nCi 241Am in the liver, thereby accounting for most of the detectable 241Am contamination in the thorax.

    Introduction. Patients with a positive sentinel lymph node biopsy may undergo delayed completion axillary dissection. Where intraoperative analysis is available, immediate completion axillary dissection can be performed. Alternatively, patients may undergo primary axillary dissection for breast cancer, historically or when preoperative assessment suggests axillary metastases. This study aims to determine if there is a difference in the total number of lymph nodes or the number of metastatic nodes harvested between the 3 possible approaches. Methods. Three consecutive comparable groups of 50 consecutive patients who underwent axillary dissection in each of the above contexts were identified from the Portsmouth Breast Unit Database. Patient demographics, clinicopathological variables, and surgical treatment were recorded. The total pathological nodal count and the number of metastatic nodes were compared between the groups. Results. There were no differences in clinico-pathological features between the three groups for all features studied with the exception of breast surgical procedure (P < 0.001). There were no differences in total nodal harvest (P = 0.822) or in the number of positive nodes harvested (P = 0.157) between the three groups. Conclusion. The three approaches to axillary clearance yield equivalent nodal harvests, suggesting oncological equivalence and robustness of surgical technique. PMID:22693673

    Purpose: To determine whether volume-based parameters on pretreatment {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography in breast cancer patients treated with mastectomy without adjuvant radiation therapy are predictive of recurrence. Methods and Materials: We retrospectively analyzed 93 patients with 1 to 3 positive axillary nodes after surgery, who were studied with {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography for initial staging. We evaluated the relationship between positron emission tomography parameters, including the maximum standardized uptake value, metabolic tumor volume (MTV), and total lesion glycolysis (TLG), and clinical outcomes. Results: The median follow-up duration was 45 months. Recurrence was observed in 11 patients. Metabolic tumor volume and TLG were significantly related to tumor size, number of involved nodes, nodal ratio, nuclear grade, estrogen receptor (ER) status, and triple negativity (TN) (all P values were <.05). In receiver operating characteristic curve analysis, MTV and TLG showed better predictive performance than tumor size, ER status, or TN (area under the curve: 0.85, 0.86, 0.79, 0.74, and 0.74, respectively). On multivariate analysis, MTV was an independent prognostic factor of locoregional recurrence-free survival (hazard ratio 34.42, 95% confidence interval 3.94-882.71, P=.0008) and disease-free survival (DFS) (hazard ratio 13.92, 95% confidence interval 2.65-103.78, P=.0018). The 3-year DFS rate was 93.8% for the lower MTV group (<53.1; n=85) and 25.0% for the higher MTV group (?53.1; n=8; P<.0001, log–rank test). The 3-year DFS rate for patients with both ER-positive status and MTV <53.1 was 98.2%; and for those with ER-negative status and MTV ?53.1 it was 25.0% (P<.0001). Conclusions: Volume-based parameters improve recurrence prediction in postmastectomy breast cancer patients with 1 to 3 positive nodes. The addition of MTV to ER status or TN has potential benefits to identify a subgroup at higher risk for recurrence.

    Introduction. There has been recent interest in validity of completion axillary node dissection after a positive sentinel node. This systematic review aims to ascertain if sentinel lymph node dissection alone was noninferior to axillary lymph node dissection for breast cancer patients who have a positive sentinel node. Method. A systematic review of the electronic databases Embase, MEDLINE, and Cochrane Register of Controlled Trials was carried out. Only randomised trials that had patients with positive sentinel node as the study sample were included in the meta-analysis using the reported hazard ratios with a fixed effect model. Results. Three randomised controlled trials and five retrospective studies were identified. The pooled effect for overall survival was HR 0.94, 95% CI [0.79, 1.19], and for disease free survival was HR 0.83, 95% CI [0.60, 1.14]. The reported rates for locoregional recurrence were similar in both groups. The surgical morbidity was found to be significantly more in patients who had underwent axillary dissection. Conclusion. Amongst patients with micrometastasis in the sentinel node, no further axillary dissection is necessary. For patients with macrometastasis in the sentinel node, it is reasonable to consider omitting axillary dissection to avoid the morbidity of the procedure. PMID:25383226

    Nodal staging is important in prostate cancer treatment. While surgical lymph node dissection is the classic method of determining whether lymph nodes harbor malignancy, this is a very invasive technique. Current noninvasive approaches to identifying malignant lymph nodes are limited. Conventional imaging methods rely on size and morphology of lymph nodes and have notoriously low sensitivity for detecting malignant nodes. New imaging techniques such as targeted positron emission tomography (PET) imaging and magnetic resonance lymphography (MRL) with iron oxide particles are promising for nodal staging of prostate cancer. In this review, the strengths and limitations of imaging techniques for lymph node staging of prostate cancer are discussed. PMID:25773350

    A 65-year-old patient with prostate adenocarcinoma was explored by F-fluorocholine (FCH) PET/CT for pretreatment staging because of a high risk of prostate cancer. Images showed multiple foci with increased uptake of F-FCH within some pelvic and retroperitoneal lymph nodes, osseous foci (iliac bones and sacrum), and much more unusual, increased uptake foci within some left supraclavicular and left axillary lymph nodes. Owing to the rarity of spread to supraclavicular lymph nodes, surgical removal was performed and revealed prostate cancer metastases. PMID:25674860

    The presence of metastases in the regional lymph nodes is the major prognostic factor in breast cancer in the absence of overt distant metastases and is also an important indicator of the need for adjuvant therapy in ''early'' breast cancer. Currently, the accurate assessment of axillary lymph node status requires axillary dissection which has an associated morbidity. An alternative method of identifying patients who are ''node positive'' has been developed by means of immunolymphoscintigraphy with s.c. administered radioiodinated monoclonal antibody. The /sup 131/I-labeled anti-breast cancer antibody (RCC-1; 400 micrograms) and cold iodine-labeled blocking antibody (Ly-2.1; 2 mg which is nonreactive with breast cancer) were injected s.c. into both arms and scintigraphy images were obtained 16-18 h after the injection, using the axilla contralateral to the side of the breast cancer as the control. Studies were reported as positive if the amount of background-subtracted radioactive count in the axilla of interest exceeded the normal side by a radio equal to or greater than 1.5:1.0 as assessed by computer analysis. In 38 of 40 patients the findings on scintigraphy were correlated with operative and histopathological findings on the axillary dissection specimen or cytological findings of fine needle aspiration of axillary lymph nodes. In a prospective study of 26 patients, the method is more sensitive (86%) and specific (92%) than preoperative clinical assessment (57% sensitivity, 58% specificity) in the detection of axillary lymph node metastases; and by combining both modalities of assessment, there was an improvement in the sensitivity (100%) but a deterioration in the specificity (50%).

    Radio-guided sentinel lymph node biopsy in early-stage breast cancer is standard of care. Freehand SPECT is a system for intraoperative visualization of radioactivity in the body. It generates a 3-dimensional image of the radioactivity distribution complementing the acoustic information of the gamma probe by providing depth and radioactive uptake information. In the reported case, freehand SPECT was used in a breast cancer patient as a control method after conventional sentinel lymph node biopsy. Freehand SPECT identified an additional lymph node, changing the original stage from pN1(mic) (micrometastasis) to pN1a (nodal positive), resulting in an axillary lymph node dissection.

    The aim of this study was to develop a technique for axillary radiotherapy that minimizes the risk of radiation-induced damage to the surrounding normal tissue (i.e., arm, shoulder, lung, esophagus, and spinal cord) while keeping the risk of a nodal recurrence to a minimum. A planning study was performed in 20 breast cancer patients. The target volume of the axillary treatment encompassed the periclavicular and axillary lymph node areas. The 3-dimensional (3D) computed tomography (CT) information in this study was used to outline the lymph node areas and the organs at risk (i.e., the esophagus, spinal cord, brachial plexus, and lung). A conventional AP-PA technique (with a transmission plate placed in the AP beam) was evaluated. In addition, a new single-isocenter technique consisting of AP/PA fields using a gantry rotation of {+-}20 deg. and a medial AP segment was developed. Both techniques were compared by evaluation of the calculated dose distributions and the dose-volume histograms of the target volume and surrounding organs at risk. The field borders and humeral shielding were redefined based on the 3D anatomical references. Adapting the humeral shielding reduced the irradiated volume by 19% and might contribute to a reduction of the incidence of arm edema and impairment of shoulder function. The maximum radiation dose in the esophagus and spinal cord was reduced by more than 50% using the single-isocenter technique. The difference between both techniques with respect to the mean doses in the target volume and lung, and the maximum dose in brachial plexus, was not statistically significant. Moreover, the single-isocenter technique allowed a fast and easy treatment preparation and reduced the execution time considerably (with approximately 10 minutes per fraction)

    Sentinel lymph node biopsy (SLNB) emerged in the 1990s as a new technique in the surgical management of the axilla for patients with early breast cancer, resulting in lower complication rates and better quality of life than axillary lymph node dissection (ALND). Today SLNB is firmly established in the armamentarium of clinicians treating breast cancer, but several questions remain. The goal of this paper is to review recent work addressing 4 questions that have been the subject of debate in the use of SLNB in the past few years: (a) What is the implication of finding micrometastases in the sentinel nodes? (b) Is ALND necessary in all patients who have a positive SLNB? (c) How accurate is SLNB after neoadjuvant therapy? (d) Can SLNB be used to stage the axilla in locally recurrent breast cancer following breast surgery with or without prior axillary surgery?

    Sentinel lymph node (SLN) mapping is a technique for assessing whether early-stage invasive breast cancer has metastasized, thus determining prognosis and treatment options. SLN identification is achieved using the blue-dye and radioactive colloids techniques, which are sometimes combined with lymphoscintigraphy. Furthermore, intra-operative gamma acoustic probes, as well as gamma imaging probes are used during surgery. The purpose of this study is the construction of a gamma probe for sentinel lymph node imaging and its optimization in terms of sensitivity with respect to spatial resolution. The reference probe has small field of view (2.5 × 2.5 cm2) and is based on a position sensitive photomultiplier tube (PSPMT) coupled to a pixellated CsI(Tl) scintillator. Following experimental validation, we simulated the system using the GATE Monte Carlo toolkit (GATE v6.1) and modeled various collimator geometries, in order to evaluate their performance and propose the optimal configuration. The constraints of the proposed gamma imaging probe are i) sensitivity close to 2 cps/kBq and ii) spatial resolution equal to 6 mm at 2 cm source-to-collimator distance and ~ 10 mm at 5 cm. An integrated structure that achieves those requirements is a tungsten collimator with 2 × 2 mm2square holes, 16 mm thickness, 0.15 mm septa, where each CsI(Tl) 2 × 2 × 5 mm3 crystal pixel is placed inside the collimator.

    The detection efficiency and interference susceptibility of four different types of low energy photon detectors, each with a unique geometric arrangement, were compared for direct measurement of Am deposited in the axillary lymph nodes. Although the most efficient detector was a single large 23,226 mm square phoswich detector, it was also the most susceptible to confounding depositions from activity deposited in adjacent organs. The array of two 2,800 mm high purity germanium detectors exhibited the highest efficiency per unit detector area with some resistance to confounding from activity deposited in the lungs. The array of two 4,560 mm NaI(Tl) detectors was the least susceptible to confounding and nearly as efficient per square millimeter as the high purity germanium detector array. Thus, selection of a detector system for in vivo measurement of activity deposited in the axillary lymph nodes should consider whether there is a likelihood for activity deposited in other organs, such as the lungs, skeleton, or liver, to create an interference that will confound the measurement result.

    Aim: Breast cancer-related lymphoedema (BCRL) is a disabling complication developing after breast cancer treatment in a proportion of patients. Its impact on quality of life becomes more substantial as survival after breast cancer diagnosis increases. The incidence of BCRL following breast cancer treatment varies due to a lack of uniform definition and measurement criteria. This review aims to determine the prevalence of BCRL following axillary lymph node dissection (ALND) as a benchmark to be used in a risk-benefit medical decision whether to proceed with ALND or not. The risk of leaving unresected non-sentinel metastatic lymph nodes with a presumed inherent risk of local recurrence will be balanced against the risk of BCRL following a potentially unnecessary ALND. Methods: Pubmed and Embase databases were searched for all publications on BCRL in order to estimate its incidence and to decide on the most appropriate measurement method to use in clinical practice. Results: 51 articles were identified on BCRL incidence and measurement technique. Most studies measured BCRL based on differences in arm circumference (n?=?18) or by self-reported symptoms (n?=?18). The weighted average of BCRL incidence following ALND measured by self-report and circumference method was 28% and 16%, respectively. Conclusion: The importance of ALND and irradiation as part of the treatment of operable breast carcinoma is well established, but its morbidity is less well documented. We argue self-report as the most appropriate method to establish a diagnosis of BCRL. Therefore a 28% risk of finding non-sentinel lymph node metastases in a completion ALND will be regarded as the cut-off in a medical decision to proceed with ALND. PMID:24753936

    Sentinel lymph node biopsy (SLNB) in gastrointestinal-(GI)-tract cancer is not yet of clinical relevance. Nevertheless, the results in the upper GI-tract promise to be helpful to individualize the indication for surgical therapy. SLNB in colon cancer still fails to show high validity to predict the nodal status, but may be helpful to clarify the prognostic role of micrometastases/isolated tumor cells. In anal cancer SLNB is able to guide the indication for groin irradiation. PMID:17726666

    In order to identify regional lymph node drainage groups of primary malignant melanomas resp. suspicious pigmented tumors on truncal skin, lymphoscintigraphy using 99mTc-Sb2S3 colloid was performed in 50 patients of either sex prior to operative treatment. The lymphatic drainage pattern proved to be practically unpredictable by conventional anatomic guidelines based on the thesis of "lymphatic watersheds". In 96 per cent of the patients examined radiocolloid uptake was to be found in one or both of the axillary lymph node groups, either solely or combined with inguinal, supraclavicular, posterior cervical or parasternal node-bearing areas. In conclusion, axillary lymph node drainage groups are the center in lymphatic drainage from the truncal skin in man. PMID:7162208

    Mastectomy with axillary dissection is still the most commonly recommended procedure for male breast cancer. The aim of this study was to retrospectively evaluate our experience in 32 male patients with early breast cancer who underwent sentinel lymph node biopsy (SLNB) and axillary dissection only in cases of metastases in the sentinel lymph node (SLN). The median age was 58 years (range, 33-80). Lymphoscintigraphy was successful in all patients, with a mean number of visualized SLNs per patient of 1.3 (range, 1-2). At surgery, the identification rate of the SLN was 100%, with a mean number of removed SLNs per patient of 1.5 (range, 1-3). Twenty-six patients had negative SLNs, six patients had positive SLNs. Two patients with metastatic SLNs had additional positive nodes. After a median follow-up of 30 months (range, 1-63) no axillary reappearance of the disease occurred. As with women, we recommend SLNB in male patients with breast cancer and clinically negative axilla. PMID:17522237

    Purpose: In many centers, supraclavicular fossa radiotherapy (SCF RT) is not routinely offered to breast cancer patients with one to three positive lymph nodes. We aimed to identify a subgroup of these patients who are at high risk of supra or infraclavicular fossa relapse (SCFR) such that they can be offered SCFRT at the time of diagnosis to improve long term locoregional control. Methods and Materials: We performed a retrospective analysis of the pathological features of 1,065 cases of invasive breast cancer with one to three positive axillary lymph nodes. Patients underwent radical breast conserving surgery or mastectomy. A total of 45% of patients received adjuvant chest wall/breast RT. No patients received adjuvant SCFRT. The primary outcome was SCFR. Secondary outcomes were chest wall/breast recurrence, distant metastasis, all death, and breast-cancer specific death. Kaplan-Meier estimates were used to calculate actuarial event rates and survival functions compared using log-rank tests. Multivariate analyses (MVA) of factors associated with outcome were conducted using Cox proportional hazards models. Results: Median follow-up was 9.7 years. SCFR rate was 9.2%. Median time from primary diagnosis to SCFR was 3.4 years (range, 0.7-14.4 years). SCFR was associated with significantly lower 10-year survival (18% vs. 65%; p < 0.001). Higher grade and number of positive lymph nodes were the most significant predictors of SCFR on MVA (p < 0.001). 10 year SCFR rates were less than 1% in all patients with Grade 1 cancers compared with 30% in those having Grade 3 cancers with three positive lymph nodes. Additional factors associated with SCFR on univariate analysis but not on MVA included larger nodal deposits (p = 0.002) and proportion of positive nodes (p = 0.003). Conclusions: Breast cancer patients with one to three positive lymph nodes have a heterogenous risk of SCFR. Patients with two to three positive axillary nodes and/or high-grade disease may warrant consideration of SCFRT.

    Background The main purpose of the study reported here was to validate the clinical value of the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram that predicts non-sentinel lymph node (SLN) metastasis in SLN-positive patients with breast cancer. Methods Data on 1,576 patients who received sentinel lymph node biopsy (SLNB) at the Shandong Cancer Hospital from December 2001 to March 2014 were collected in this study, and data on 509 patients with positive SLN were analyzed to evaluate the risk factors for non-SLN metastasis. The MSKCC nomogram was used to estimate the probability of non-SLN metastasis and was compared with actual probability after grouping into deciles. A receiver-operating characteristic (ROC) curve was drawn and predictive accuracy was assessed by calculating the area under the ROC curve. Results Tumor size, histological grade, lymphovascular invasion, multifocality, number of positive SLNs, and number of negative SLNs were correlated with non-SLN metastasis (P<0.05) by univariate analysis. However, multivariate analysis showed that tumor size (P=0.039), histological grade (P=0.043), lymphovascular invasion (P=0.001), number of positive SLNs (P=0.001), and number of negative SLNs (P=0.000) were identified as independent predictors for non-SLN metastasis. The trend of actual probability in various decile groups was comparable to the predicted probability. The area under the ROC curve was 0.722. Patients with predictive values lower than 10% (97/492, 19.7%) had a frequency of non-SLN metastasis of 17.5% (17/97). Conclusion The MSKCC nomogram can provide an accurate prediction of the probability of non-SLN metastasis, and offers a reference basis about axillary lymph node dissection. Axillary lymph node dissection could be avoided in patients with predictive values lower than 10%.

    Axillary lymph nodes were separated from 492 radical or modified radical mastectomies for primary breast cancer and examined according to their anatomical level corresponding to their position along the theoretical pathway of lymph drainage from the breast. The patterns of metastasis and the relationship between metastatized levels and disease-free survival were investigated to see whether complete axillary dissection is necessary for the staging and the planning of adjuvant therapy in breast cancer. Progressive involvement from level I (proximal) to level III (distal) was found in 206 specimens (80.8% of tumors with axillary metastases), while discontinuous or "skip" metastases were present in 49 (19.2%), including 38 (14.9%) with positive nodes at level II or III but not at level I. "Skip" metastasis was more frequent when fewer than four nodes were positive, and not related to either the size of the primary tumor or its location. The effect of age, menopausal status, tumor size, node status, number of positive nodes, anatomic level of axillary node involvement, estrogen and progesterone receptors, and adjuvant therapies on disease-free survival was evaluated using a multivariate proportional hazard model and life table analysis. This showed that disease-free survival was strongly related to the number of positive nodes (P less than 0.001), tumor size (P = 0.001) and level of node involvement (P = 0.01) as independent prognostic factors. Moreover, the subset of patients with four or more positive nodes and involvements of level III had a higher risk of recurrence (25% recurrence-free patients 5 years after mastectomy). The high frequency of "skip" metastases and the prognostic value of both the level of involvement and the number of metastatic nodes suggest that a complete axillary dissection is needed in the surgical management of breast cancer to obtain all the data useful in the planning of adjuvant therapy.

    Lymph node status remains one of most crucial indicators of gastric cancer prognosis and treatment planning. Current imaging methods have limited accuracy in predicting lymph node metastasis. We sought to identify protein markers in primary gastric cancer and to define a risk model to predict lymph node metastasis. The Protein Pathway Array (PPA) (initial selection) and Western blot (confirmation) were used to assess the protein expression in a total of 190 freshly frozen gastric cancer samples. The protein expression levels were compared between samples with lymph node metastasis (n = 73) and those without lymph node metastasis (n = 57) using PPA. There were 27 proteins differentially expressed between lymph node positive samples and lymph node negative samples. Five proteins (Factor XIII B, TFIIH p89, ADAM8, COX-2 and CUL-1) were identified as independent predictors of lymph node metastasis. Together with vascular/lymphatic invasion status, a risk score model was established to determine the risk of lymph node metastasis for each individual gastric cancer patient. The ability of this model to predict lymph node metastasis was further confirmed in a second cohort of gastric cancer patients (33 with and 27 without lymph node metastasis) using Western blot. This study indicated that some proteins differentially expressed in gastric cancer can be selected as clinically useful biomarkers. The risk score model is useful for determining patients' risk of lymph node metastasis and prognosis. PMID:23011604

    An increasingly early diagnosis for discovering breast cancer, an improvement of surgical procedures with refining techniques for research and study of sentinel node, currently allow a more conservative surgical approach. Association with suitable chemo-radiotherapy allows a good control of breast disease. Our study, although modest, was carried out on 63 patients suffering from breast cancer, who underwent surgical treatment with assessment of sentinel lymph node. Aim of study was to establish the most correct strategy in the presence of isolated tumor cells (ITC) and/or micro-metastases of sentinel lymph node. Many studies have been carried out to find which was the most appropriate treatment, nevertheless, in the absence of univocal guidelines, we prefer to proceed to axillary dissection, though the topic is very debated and controversial. Following this strategy we obtained quite satisfactory results. PMID:25644726

    IMPORTANCE Sentinel lymph node biopsy (SLNB) is the standard of care for axillary staging in clinically node-negative breast cancer patients. It is not known whether SLNB rates differ by surgeon expertise. If surgeons with less breast cancer expertise are less likely to offer SLNB to clinically node-negative patients, this practice pattern could lead to unnecessary axillary lymph node dissections (ALND) and lymphedema. OBJECTIVE To explore potential measures of surgical expertise (including a novel objective specialization measure – percentage of a surgeon’s operations devoted to breast cancer determined from claims) on the use of SLNB for invasive breast cancer. DESIGN Population-based prospective cohort study. Patient, tumor, treatment and surgeon characteristics were examined. SETTING California, Florida, Illinois PARTICIPANTS Elderly (65+ years) women identified from Medicare claims as having had incident invasive breast cancer surgery in 2003. MAIN OUTCOME MEASURES Type of axillary surgery performed. RESULTS Of the 1,703 women treated by 863 different surgeons, 56% underwent an initial SLNB, 37% initial ALND and 6% no axillary surgery. The median annual surgeon Medicare volume of breast cancer cases was 6 (range: 1.5–57); the median surgeon percentage of breast cancer cases was 4.6% (range: 0.7%–100%). After multivariable adjustment of patient and surgeon factors, women operated on by surgeons with higher volumes and percentages of breast cancer cases had a higher likelihood of undergoing SLNB. Specifically, women were most likely to undergo SLNB if operated on by high volume surgeons (regardless of percentage) or by lower volume surgeons with a high percentage of cases devoted to breast cancer. In addition, membership in the American Society of Breast Surgeons (OR 1.98, CI 1.51–2.60) and Society of Surgical Oncology (OR 1.59, CI 1.09–2.30) were independent predictors of women undergoing an initial SLNB. CONCLUSIONS AND RELEVANCE Patients treated by surgeons with more experience and focus in breast cancer were significantly more likely to undergo SLNB, highlighting the importance of receiving initial treatment by specialized providers. Factors relating to specialization in a particular area, including our novel surgeon percentage measure, require further investigation as potential indicators of quality of care. PMID:24369337

    Purpose: To test the difference in treatment outcome between breast-conservation surgery with radiation and total mastectomy without radiation, to evaluate the benefits of adjuvant radiotherapy in patients with one to three positive axillary lymph nodes. Methods and Materials: Using the Severance Hospital Breast Cancer Registry, we divided the study population of T1, T2 and one to three axillary node-positive patients into two groups: breast-conservation surgery with radiation (BCS/RT) and total mastectomy without radiation (TM/no-RT). Data related to locoregional recurrence, distant recurrence, and death were collected, and survival rates were calculated. Results: The study population consisted of 125 patients treated with BCS/RT and 365 patients treated with TM/no-RT. With a median follow-up of 68.4 months, the 10-year locoregional recurrence-free survival rate with BCS/RT and TM/no-RT was 90.5% and 79.2%, respectively (p = 0.056). The 10-year distant recurrence-free survival rate was 78.8% for patients treated with BCS/RT vs. 68.0% for those treated with TM/no-RT (p = 0.012). The 10-years overall survival rate for patients treated with BCT/RT and TM/no-RT was 87.5% and 73.9%, respectively (p = 0.035). After multivariate analysis, patients treated with BCT/RT had better distant recurrence-free survival (hazard ratio [HR], 0.527; 95% confidence interval [CI], 0.297-0.934; p = 0.028), with improving locoregional recurrence-free survival (HR, 0.491; 95% CI, 0.231-1.041; p = 0.064) and overall survival trend (HR, 0.544; 95% CI, 0.277-1.067; p = 0.076). Conclusions: This study provides additional evidence that adjuvant radiation substantially reduces local recurrence, distant recurrence, and mortality for patients with one to three involved nodes.

    Lymph node micrometastases in gastric cancer are based on the definition in the 6th version of the TNM classification of malignant tumours edited by the International Union Against Cancer, which is also quoted in the 14th version of the Japanese Classification of Gastric Carcinoma. Histopathologic examination such as immunohistochemistry and molecular biological techniques including RT-PCR and one-step nucleic acid amplification are used for the detection of micrometastases. Because the time required for such detection is shortened to 30 to 40 min, intraoperative detection is feasible. Many papers have reported the correlation between micrometastases and prognosis in gastric cancer, although whether micrometastases are correlated with poor prognosis even when completely resected remains unknown. Intraoperative detection of micrometastases is important to decide the operative procedure in sentinel node navigation surgery. PMID:23457939

    Purpose: To determine the risk of regional-nodal recurrence in patients with early-stage, invasive breast cancer, with clinically negative axillary nodes, who were treated with breast-conserving surgery, 'high tangential' breast radiotherapy, and hormonal therapy, without axillary surgery or the use of a separate nodal radiation field. Methods and Materials: Between September 1998 and November 2003, 74 patients who were {>=}55 years of age with Stage I-II clinically node-negative, hormone-receptor-positive breast cancer underwent tumor excision to negative margins without axillary surgery as a part of a multi-institutional prospective study. Postoperatively, all underwent high-tangential, whole-breast radiotherapy with a boost to the tumor bed, followed by 5 years of hormonal therapy. Results: For the 74 patients enrolled, the median age was 74.5 years, and the median pathologic tumor size was 1.2 cm. Lymphatic vessel invasion was present in 5 patients (7%). At a median follow-up of 52 months, no regional-nodal failures or ipsilateral breast recurrences had been identified (95% confidence interval, 0-4%). Eight patients died, one of metastatic disease and seven of other causes. Conclusion: In this select group of mainly older patients with early-stage hormone-responsive breast cancer and clinically negative axillary nodes, treatment with high-tangential breast radiotherapy and hormonal therapy, without axillary surgery, yielded a low regional recurrence rate. Such patients might be spared more extensive axillary treatment (axillary surgery, including sentinel node biopsy, or a separate nodal radiation field), with its associated time, expense, and morbidity.

    Using a size criterion of 1 cm or greater as evidence for abnormality, the size of mediastinal lymph nodes identified by computed tomography (CT) was a poor predictor of mediastinal lymph node metastases in a series of 86 patients who had surgery for bronchogenic carcinoma. The surgery included full nodal sampling in all patients. Of the 86 patients, 36 had nodes greater than or equal to 1 cm identified by CT. Of the 21 patients with mediastinal metastases proven at surgery, 14 had nodes greater than or equal to 1 cm (sensitivity = 67%). Of the 65 patients without mediastinal metastases, 22 had nodes greater than or equal to 1 cm. Obstructive pneumonia and/or pulmonary collapse distal to the cancer was present in 39 patients (45%). Obstructive pneumonia and/or pulmonary collapse is a common occurrence in bronchogenic carcinoma, but mediastinal nodes greater than or equal to 1 cm in this circumstance cannot be presumed to represent metastatic disease. Metastatic mediastinal lymph node involvement was related to nodal size also in patients with evidence of prior granulomatous disease and in patients with no putative benign cause for nodes greater than or equal to 1 cm.

    Background Metastasis in the axillary lymph nodes is the most important known prognostic factor for breast cancer. We aimed to investigate the contribution of the radioisotope tracer method to the dye-only method by performing sentinel lymph node biopsy on the same patient group during a single surgical session. Methods Forty-two patients who underwent operations in our clinic from February 2010 to October 2011 and with masses of <5 cm and clinically and radiologicallly negative axilla (T1-2 N0) were prospectively included in this study. After paraffin examination results were obtained, the numbers and metastatic states of the lymph nodes that were unidentifiable during surgery (although they were stained) but were detected by a gamma probe, lymph nodes that were only stained, lymph nodes that were only radioactive (hot), and lymph nodes that were both stained and radioactive (stained-hot) were determined in all patients. In patients who underwent axillary lymph node dissection, the total numbers of lymph nodes removed and their metastatic states were determined separately. Results At least one blue-stained sentinel lymph node was identified in all patients during the blue-stained lymph node detection stage. The average number of sentinel nodes removed at this stage was 2.1?±?1.1. In the second surgical stage (the stage in which nodes with axillary counts were investigated with the gamma probe) in these 41 patients, at least one additional hot node was removed, or at least one of the nodes that was removed because it was blue was also hot. In addition to the lymph nodes removed in the dye stage, 34 hot lymph nodes were excised from 21 patients. Overall, the average number of hot lymph nodes removed was 2.9?±?1.5. In all patients, subsequent frozen sections and histopathological examinations were 100% concordant with the sentinel lymph nodes that were removed; the stained sentinel lymph nodes that were removed first did not affect the decision to perform axillary dissection. Conclusion The results of our study indicate that performing sentinel lymph node biopsy with dye only is sufficient and as effective as the combined method. PMID:23617459

    Breast cancer (BC) is currently a heterogeneous disease with variations in clinical behaviour. Classification according to subtypes has allowed progress in the individualisation of treatment. The objective of this study is to evaluate the risk of axillary node compromise in patients with BC, according to clinicopathologic subtypes. Materials and methods are a retrospective, descriptive-analytical study. All patients that had undergone surgery for invasive BC were included, with the study of sentinel lymph nodes (SLNs) at Hospital Clínico de la Pontificia Universidad Católica, between May 1999 and December 2012. The results showed 632 patients fulfilled the inclusion criteria, with the median age being 55 years (range: 28–95), and 559 (88.4%) patients presented with estrogen receptor and/or progesterone receptor positive tumours. Luminal A: 246 patients (38.9%), luminal B: 243 (38.4%), luminal not otherwise specified: 70 (11.1%) triple negative (TN): 60 (9.5%) and over expression of epidermal growth factor type 2 receptor (HER2 positive): 13 (2.1%). Luminal tumours displayed a greater risk of metastasis in the SLNs, but this difference was not statistically significant (p = 0.67). TN and HER2 positive tumours presented the greatest proportion of metastatic compromise in non-sentinel lymph nodes (non-SLNs) (57.1% and 50%, respectively). The presence of macrometastasis (MAM) in the SLN was associated with a greater risk of compromise of the non-SLN. Conclusions: Luminal tumours are the most frequent and present a greater proportion of axillary lymph node compromise, without being statistically significant. TN and HER2 positive tumours tend to have a higher axillary compromise; however, this was not statistically significant in either. Only the presence of MAM in SLNs displayed a statistically significantly association in the compromise of non-SLNs. PMID:25114720

    The aim of this study was to retrospectively determine the accuracy and feasibility of using 99mTc-dextran (DX) lymphoscintigraphy for the localization of sentinel lymph nodes (SLNs) in breast cancer patients. The relevant factors affecting lymphoscintigraphy were also investigated. In this study, 235 breast cancer patients underwent 99mTc-DX lymphoscintigraphic imaging and examination by a ?-probe method in combination with blue dye staining to detect SLNs. The detection results were considered in combination with rapid frozen pathology results to determine whether SLN metastasis was positive or negative. SLNs were identified in 191 patients by ?-probe detection among the 202 patients that tested positive by lymphoscintigraphic imaging, a coincidence rate of 94.6%. This suggested that lymph node metastasis had occurred and could be detected using lymphoscintigraphy. The axillary status of the breast cancer patients was also predicted using lymphoscintigraphy and the false-negative rate, sensitivity, specificity and positive predictive value were 13.3% (4/30), 90.7% (39/43), 23.4% (45/192) and 13.5% (21/155), respectively. The age of the patient, menstrual status, tumor location, tumor size, pathological type, preoperative biopsy and neoadjuvant chemotherapy were unrelated to the success of lymphoscintigraphy (P>0.05). 99mTc-DX lymphoscintigraphy is able to exactly determine the location of SLN in breast cancer patients, and can be used for guiding ?-probe methods and sentinel lymph node biopsy.

    To evaluate differences in use of sentinel lymph node biopsy (SLNB) by age and race in Medicare recipients with early-stage breast cancer, we examined Surveillance, Epidemiology and End Results—Medicare linked data for women undergoing breast conserving surgery for stage I or II breast cancer, including axillary staging, between January 2000 and December 2002. Multivariable generalized linear modeling with generalized estimating equations was used to identify predictors of receiving SLNB versus standard axillary lymph node dissection as the primary axillary staging modality. Women were significantly less likely to receive SLNB as their primary staging procedure if they were African American (OR 0.65), greater than 80 years of age (OR 0.71 vs. age <70), or dually eligible for Medicare and Medicaid (OR 0.61). Tumor characteristics, including well-differentiated histology and stage I disease, were associated with increased likelihood of SLNB, but estrogen receptor status was not a significant predictor. Women treated at an institution affiliated with an NCI cooperative research group had significantly greater likelihood of receiving SLNB (OR 2.31). Likelihood of receiving SLNB increased for women diagnosed in 2001 and 2002 compared with 2000. Significant disparities exist in receipt of SLNB in the Medicare population, with African Americans, the elderly, and economically disadvantaged patients being less likely to receive this innovative and morbidity-sparing procedure. These findings continue a previously observed pattern of reduced access to state of the art breast cancer care among underserved populations. PMID:21340480

    Pathologic axillary lymph node (ALN) status is an important prognostic factor for staging breast cancer. Currently, status is determined by histopathology following surgical excision of sentinel lymph node(s), which is an invasive, time consuming, costly and potentially morbid procedure. This work describes an imaging platform for the non-invasive assessment of ALN status, eliminating the need for operation in patients without nodal involvement. A targeted imaging probe (MamAb-680) was developed by conjugation of a mammaglobin-A specific monoclonal antibody to a near-infrared fluorescent dye. Using DNA and tissue microarray, mammaglobin-A was validated as a cell-surface target that is expressed in axillary lymph node positive patient samples but is not expressed in normal lymph nodes. In vivo selectivity was determined by intravenous injection of MamAb-680 into mice with mammaglobin-A positive and negative mammary fat pad (MFP) tumors; and by peritumoral MFP injection of the targeted imaging probe in mice with spontaneous ALN metastases. Fluorescence imaging showed that probe was only retained in positive tumors and metastases. As few as 1000 cells that endogenously express mammaglobin-A were detected in ALN indicating high sensitivity of this method. Hence, this approach has potential for translation into clinical use for the non-invasive staging of breast cancer. PMID:21169406

    The presence of lymph node metastasis is a key prognostic factor in colorectal cancer and lymph node yield is an important parameter in assessing the quality of histopathology reporting of colorectal cancer excision specimens. This study assesses the trend in lymph node evaluation over time in a single institution and the relationship with the identification of lymph node positive tumours. It compares the lymph node yield of a contemporary dataset compiled from the histopathology reports of 2178 patients who underwent surgery for primary colorectal cancer between 2005 and 2012 with that of a historic dataset compiled from the histopathology reports of 1038 patients who underwent surgery for colorectal cancer at 5 yearly intervals from 1975 to 2000. The mean lymph node yield was 14.91 in 2005 rising to 21.38 in 2012. In 2012 92.9% of all cases had at least 12 lymph nodes examined. Comparison of the mean lymph node yield and proportion of Dukes C cases shows a significant increase (Pearson correlation?=?0.927, p?=?0.001) in lymph node yield while there is no corresponding significant trend in the proportion of Dukes C cases (Pearson correlation?=??0.138, p?=?0.745). This study shows that there is increasing yield of lymph nodes from colorectal cancer excision specimens. However, this is not necessarily associated with an increase number of lymph node positive cancers. Further risk stratifying of colorectal cancer requires consideration of other pathological parameters especially the presence of extramural venous invasion and relevant biomarkers. PMID:25118594

    Prostate cancer is the most common cancer in men, often presenting with regional lymph node or bone metastasis and rarely with supradiaphragmatic lymph node involvement. Most metastatic cancers involving the cervical lymph nodes are from cancers of the upper aerodigestive tract. In this report, we describe two cases with cervical lymph node enlargement due to metastatic prostate cancer as the initial clinical presentation: a 43-year-old male, initially misdiagnosed with a tumor of the upper aerodigestive tract and an 87-year-old male with right lobe pneumonia and cervical lymph node enlargement, initially attributed to be an acute inflammatory lymph node reaction. To the best of our knowledge, there are less than 50 cases reported in the literature of adenocarcinoma of prostate metastatic to the cervical lymph nodes and only one case presenting in men younger than 45 years. The authors intend to highlight the importance of digital rectal exam and PSA test in case of persistent left cervical lymph node enlargement, including men younger than 45 years of age.

    The present study aimed to determine the toxicity and efficacy of 4 courses of anthracyclines-taxane (AT) chemotherapy followed by radiation therapy (XRT) concurrent with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) in surgically resected axillary node-positive (N+) breast cancer. A total of 200 women with N+ breast cancer were treated with adriamycin and docetaxel followed by XRT concurrent with six courses of CMF. Two courses of dose-dense chemotherapy with ifosfamide, carboplatin and etoposide, supported by pegfilgrastim, were administered to patients with >5 histologically confirmed axillary lymph node metastases and patients with triple-negative disease. Additional treatments included 1 year of trastuzumab in human epidermal growth factor receptor 2-positive patients, 5 years of a luteinizing hormone-releasing hormone analogue in premenopausal women and 5 years of an aromatase inhibitor (AI) in estrogen receptor-positive (ER+) patients. The mean number of positive axillary lymph nodes was 4.4 (range, 2-37), 52% of the patients were premenopausal, 74% were ER+ and 26% had triple-negative disease. After a median follow-up of 73 months, grade 2 and 3 hematological toxicity was observed in 20% of the patients. The 10-year disease-free survival (DFS) and overall survival (OS) rates were 73 and 77%, respectively. There was no significant difference in DFS between ER+ and estrogen receptor-negative (ER-) patients (P>0.05), whereas the OS was better in ER+ vs. ER- patients (P<0.05) and in premenopausal vs. postmenopausal patients (P<0.005). In conclusion, induction AT concurrent CMF and XRT and dose-dense chemotherapy followed by AI in N+ high-risk breast cancer was associated with a low level of systemic and late cardiac toxicity and excellent local control, DFS and OS.

    Background Intratumoral heterogeneity may help drive resistance to targeted therapies in cancer. In breast cancer, the presence of nodal metastases is a key indicator of poorer overall survival. The aim of this study was to identify somatic genetic alterations in early dissemination of breast cancer by whole genome next generation sequencing (NGS) of a primary breast tumor, a matched locally-involved axillary lymph node and healthy normal DNA from blood. Methods Whole genome NGS was performed on 12 µg (range 11.1–13.3 µg) of DNA isolated from fresh-frozen primary breast tumor, axillary lymph node and peripheral blood following the DNA nanoball sequencing protocol. Single nucleotide variants, insertions, deletions, and substitutions were identified through a bioinformatic pipeline and compared to CIN25, a key set of genes associated with tumor metastasis. Results Whole genome sequencing revealed overlapping variants between the tumor and node, but also variants that were unique to each. Novel mutations unique to the node included those found in two CIN25 targets, TGIF2 and CCNB2, which are related to transcription cyclin activity and chromosomal stability, respectively, and a unique frameshift in PDS5B, which is required for accurate sister chromatid segregation during cell division. We also identified dominant clonal variants that progressed from tumor to node, including SNVs in TP53 and ARAP3, which mediates rearrangements to the cytoskeleton and cell shape, and an insertion in TOP2A, the expression of which is significantly associated with tumor proliferation and can segregate breast cancers by outcome. Conclusion This case study provides preliminary evidence that primary tumor and early nodal metastasis have largely overlapping somatic genetic alterations. There were very few mutations unique to the involved node. However, significant conclusions regarding early dissemination needs analysis of a larger number of patient samples. PMID:25546409

    The number of lymph nodes removed is one of the important predictors for survival in breast cancer study. Our aim is to determine the optimal number of lymph nodes to be removed for maximizing the survival of breast cancer patients. The study population consists of 873 patients with at least one of axillary nodes involved among 1890 patients from the University of Malaya Medical Center (UMMC) breast cancer registry. For this study, the Chi-square test of independence is performed to determine the significant association between prognostic factors and survival status, while Wilcoxon test is used to compare the estimates of the hazard functions of the two or more groups at each observed event time. Logistic regression analysis is then conducted to identify important predictors of survival. In particular, Akaike's Information Criterion (AIC) are calculated from the logistic regression model for all thresholds of node involved, as an alternative measure for the Wald statistic (?2), in order to determine the optimal number of nodes that need to be removed to obtain the maximum differential in survival. The results from both measurements are compared. It is recommended that, for this particular group, the minimum of 10 nodes should be removed to maximize survival of breast cancer patients.

    Summary Background The aim of this study was to identify the axillopectoral muscle anomaly commonly known as Langer's axillary arch, and to understand its importance in surgical procedures of the axilla. Patients and Methods Between 2009 and 2011, 758 patients underwent sentinel lymph node biopsy, axillary dissection, or both. Patients with Langer's axillary arch were identified and assessed retrospectively. The decision to cut or preserve the axillary arch was made based on clinical judgment, and patients were followed-up accordingly to monitor for adverse outcomes. Results Of the 758 patients who underwent axillary procedures, 9 (1.2%) were found to have a Langer's axillary arch. In 2 patients the arch was cut, and in 7 patients it was preserved. No adverse outcomes were identified in any of the patients upon follow-up. Conclusion Langer's axillary arch is a unique anatomic anomaly of the axillary region that may be problematic due to the potential risks of lymphedema and vascular or nerve compression. It is important for surgeons and radiologists alike to be aware of this anatomic variation in order to properly identify it and respond appropriately based on clinical judgment, and to complete close follow-up of the patient due to the potentially increased risk of adverse outcomes.

    Large field of view gamma cameras are widely used to perform lymphoscintigraphy in the sentinel lymph nodes (SLN) procedure in case of breast cancer. However, they are not specified for this application and their sizes do not enable their use in the operative room to control the excision of the all SLN. We present the results obtained with a prototype of a new mini gamma camera developed especially for the operative lymphoscintigraphy of the axillary area in case of breast cancer. This prototype is composed of 10 mm thick parallel lead collimator, a 2 mm thick GSO:Ce inorganic scintillating crystal from Hitachi and a Hamamatsu H8500 flat panel multianode (64 channels) photomultiplier tube (MAPMT) equipped with a dedicated electronics. Its actual field of view is 50 × 50mm2. The gamma interaction position in the GSO scintillating plate is obtained by calculating the center of gravity of the fired MAPMT channels. The measurements performed with this prototype demonstrate the usefulness of this mini gamma camera for the pre, per and post-operative identification of SLN's and how its complementary role with an intraoperative handheld gamma probe enables to improve the efficiency of this practice. A 100 × 100mm2 field of view camera designated to cover the entire axillary area is under investigation.

  19. Reactivity of axillary lymph-nodes draining invasive breast carcinomas - immunohistochemical evidence of tumor-associated reactions of B-region and T-region.

    1994-03-01

    The B and T regions in 495 axillary lymph nodes (TU-LN) draining 104 invasive breast carcinomas and 34 non-tumor-draining axillary/cervical lymph nodes (R-LN) were investigated immunohistochernically in frozen sections. The extents of the B regions and T regions were evaluated by staining with TO15 (CD22) and Leu-1 (CD5), respectively. Staining with Ki-M4, which specifically recognizes follicular dendritic cells, enabled determination of the number of lymphatic follicles. The germinal-center index (GCI), the numerical ratio of primary to secondary follicles, was determined to quantify the reactivity of the B regions. The number of Ki-67+ proliferating lymphoid cells per 0.5 mm(2) T region (PCT) was assessed as an index of the reactivity of the T regions. (i) In the TU-LN, the median GCI and PCT (0.1 and 18, respectively) were significantly lower than in the R-LN (0.6 and 26, respectively; both p<0.01). (ii) Greater TU-LN volumes were found to be associated with predominance of the T regions, high GCIs, and high PCTs. (iii) Higher GCIs and PCTs were associated with predominance of the T regions in TU-LN in general, but TU-LN partially destroyed by tumor metastases exhibited higher GCIs and PCTs when there was predominance of the B regions. The findings of the study show that LN draining breast carcinomas and reactive LN with signs of chronic nonspecific lymphadenitis exhibit significant immunohistochemical differences but it remains open to speculation whether the malignant tumor exerts suppressive effects on the lymphoreticular tissue or whether its antigenicity is low, particularly when compared with common, mostly infectious stimuli leading to chronic lymphadenitis.

    BACKGROUND It remains unclear how many sentinel lymph nodes (SLNs) must be removed to accurately predict lymph node status during SLN dissection in breast cancer. The objective of this study was to determine how many SLNs need to be removed for accurate lymph node staging and which patient and tumor characteristics influence this number. METHODS The authors reviewed data for all patients in their prospective database with clinical tumor, lymph node, metastasis (TNM) T1 through T3, N0, M0 breast cancer who underwent lymphatic mapping at their institution during the years 1994 through 2006. There were 777 patients who had at least 1 SLN that was positive for cancer. Simple and multiple quantile regression analyses were used to determine which patient and tumor characteristics were associated with the number of positive SLNs. The baseline number of SLNs that needed to be dissected for detection of 99% of positive SLNs in the total group of patients also was determined. RESULTS The mean number of SLNs removed in the 777 lymph node-positive patients was 2.9 (range, 1-13 SLNs). Greater than 99% of positive SLNs were identified in the first 5 lymph nodes removed. On univariate analysis, tumor histology, patient race, tumor location, and tumor size significantly affected the number of SLNs that needed to be removed to identify 99% of all positive SLNs. On multivariate analysis, mixed ductal and lobular histology, Caucasian race, inner quadrant tumor location, and T1 tumor classification significantly increased the number of SLNs that needed to be removed to achieve 99% recovery of all positive SLNs. CONCLUSIONS In general, the removal of a maximum of 5 SLNs at surgery allowed for the recovery of >99% of positive SLNs in patients with breast cancer. The current findings indicated that tumor histology, patient race, and tumor size and location may influence this number. PMID:18457326

    Background: Extracapsular tumor spread (ECS) has been identified as a possible risk factor for breast cancer recurrence, but controversy exists regarding its role in decision making for regional radiotherapy. This study evaluates ECS as a predictor of local, axillary, and supraclavicular recurrence. Patients and methods: International Breast Cancer Study Group Trial VI accrued 1475 eligible pre- and perimenopausal women with node-positive breast cancer who were randomly assigned to receive three to nine courses of classical combination chemotherapy with cyclophosphamide, methotrexate, and fluorouracil. ECS status was determined retrospectively in 933 patients based on review of pathology reports. Cumulative incidence and hazard ratios (HRs) were estimated using methods for competing risks analysis. Adjustment factors included treatment group and baseline patient and tumor characteristics. The median follow-up was 14 years. Results: In univariable analysis, ECS was significantly associated with supraclavicular recurrence (HR?=?1.96; 95% confidence interval 1.23–3.13; P = 0.005). HRs for local and axillary recurrence were 1.38 (P = 0.06) and 1.81 (P = 0.11), respectively. Following adjustment for number of lymph node metastases and other baseline prognostic factors, ECS was not significantly associated with any of the three recurrence types studied. Conclusions: Our results indicate that the decision for additional regional radiotherapy should not be based solely on the presence of ECS. PMID:18385202

We examined the consistency of the OSNA assay with a classic hematoxylin-eosin (H&E)-based immunohistochemistry (IHC) study and evaluated how OSNA-based axillary staging might impact the therapeutic management of BC patients. SLN biopsy results were considered to be positive in 60 patients (40%) in the OSNA group (N = 148) and in 43 (28%) patients in the IHC cohort (N = 153, p = 0.023). There was no difference in the macrometastasis (22% for OSNA, 15% for H&E, p = 0.139) or micrometastasis (19% for OSNA, 13% for H&E, p = 0.166) rates, but we found statistically significant differences in the number of isolated tumor cells (1% for OSNA, 11% for H&E, p < 0.001). There were no differences in the administration rate of adjuvant systemic therapy between the OSNA (66% in the SLN+ patients) and the H&E (74% in the SLN+ patients) groups (p = 0.159). The OSNA assay allows for the detection of SLN metastases more precisely than conventional pathologic methods but does not alter the therapeutic management of SLN+ BC patients. PMID:25034150

    The question of what constitutes an adequate axillary dissection for breast cancer remains open for debate. Central to this controversy is whether axillary nodal metastasis occurs in a stepwise fashion or spreads sporadically, creating skip metastases. The therapeutic aim of axillary dissection also must be considered. To resolve this controversy, a prospective study involving 129 patients who underwent complete axillary dissection for breast carcinoma was performed. The tissue from the axillary dissections was divided intraoperatively and sent to the pathologist as two specimens. The first specimen contained all nodes lateral to the pectoralis minor muscle (Level I), whereas the second contained all nodes beneath and medial to the pectoralis minor (Levels II and III). The tissue was analyzed to determine the frequency of skip metastasis. Only two patients, 1.6 per cent of the total group or 3.2 per cent of the positive node group, were found to have a positive node in Level II-III with no metastasis in Level I. A thorough dissection of Level I alone is sufficient to detect more than 98 per cent of all axillary lymph node metastases from breast cancer. Thus, proper staging of the disease can be obtained. When Level I contained positive nodes, the probability of metastatic disease to higher levels was significant (45%), indicating further treatment is necessary in incomplete axillary dissections.

    Purpose: To assess the prognostic value of the number of negative lymph nodes (NLNs) in breast cancer patients with positive axillary lymph nodes after mastectomy and its predictive value for radiotherapy efficacy of different breast cancer subtypes (BCS). Methods: The records of 1,260 breast cancer patients with positive axillary lymph nodes who received mastectomy between January 1998 and December 2007 were reviewed. The prognostic impact and predictive value of the number of NLNs with respect to locoregional recurrence-free survival (LRFS), disease-free survival (DFS), and overall survival (OS) were analyzed. Results: The median follow-up time was 58 months, and 444 patients (35.2%) received postmastectomy radiotherapy (PMRT). Univariate and multivariate Cox survival analysis indicated the number of NLNs was an independent prognostic factor of LRFS, DFS, and OS. Patients with a higher number of NLNs had better survival. PMRT improved the LRFS of patients with ? 8 NLNs ( p < 0.001), while failing to improve the LRFS of patients with > 8 NLNs (p = 0.075). In patients with luminal A subtype, PMRT improved the LRFS, DFS, and OS of patients with ? 8 NLNs, but in patients with > 8 NLNs only the LRFS was improved. For patients with luminal B subtype, PMRT only improved the LRFS of patients with ? 8 NLNs. The number of NLNs had no predictive value for the efficacy with PMRT in Her2+ and triple-negative subtypes. Conclusions: The number of NLNs is a prognostic indicator in patients with node-positive breast cancer, and it can predict the efficacy of PMRT according to different BCS. PMID:25663944

    Purpose: To determine the long-term outcome of a consistent treatment approach with electron beam postmastectomy radiation therapy (PMRT) in breast cancer patients with {>=}10 positive nodes treated with combined-modality therapy. Methods and Materials: TSixty-three breast cancer patients with {>=}10 positive lymph nodes were treated with combined-modality therapy using an electron beam en face technique for PMRT at University of Florida. Patterns of recurrence were studied for correlation with radiation fields. Potential clinical and treatment variables were tested for possible association with local-regional control (LRC), disease-free survival (DFS), and overall survival (OS). Results: TAt 5, 10, and 15 years, OS rates were 57%, 36%, and 27%, respectively; DFS rates were 46%, 37%, and 34%; and LRC rates were 87%, 87%, and 87%. No clinical or treatment variables were associated with OS or DFS. The use of supplemental axillary radiation (SART) (p = 0.012) and pathologic N stage (p = 0.053) were associated with improved LRC. Patients who received SART had a higher rate of LRC than those who did not. Moderate to severe arm edema developed in 17% of patients receiving SART compared with 7% in patients not treated with SART (p = 0.28). Conclusions: TA substantial percentage of patients with {>=}10 positive lymph nodes survive breast cancer. The 10-year overall survival in these patients was 36%. The addition of SART was associated with better LRC.

    Sentinel lymph node (SN) biopsy in primary breast cancer seems to be an alternative to complete axillary lymph node dissection for evaluation of the axillary lymph node status in selected patients. Following evaluation of the technique of SN biopsy, we applied SN biopsy clinically to 23 selected patients. A lymphoscintigraphy was performed preoperatively to evaluate lymphatic drainage. The SN was identified in the operating room by use of a hand-held gamma camera and a blue vital dye. The SN was found in all 23 patients. In 17/23 the SN was tumor free and no axillary dissection was performed; 6/23 showed a positive SN and complete axillary dissection was done. Intraoperative lymphatic mapping and SN biopsy may be the treatment of choice for evaluation of axillary node status in selected patients, for it combines accurate nodal staging and low morbidity.

    Purpose This study aimed to identify the effect of breast cancer subtype on nonsentinel lymph node (NSLN) metastasis in patients with a positive sentinel lymph node (SLN). Methods The records of 104 early breast cancer patients with a positive SLN between April 2009 and September 2013 were retrospectively evaluated. All patients underwent axillary lymph node dissection. The effects of the tumor subtype (luminal A, luminal/HER2+, human epidermal growth factor receptor 2 [HER2] overexpression, and triple-negative) and other clinicopathological factors on NSLN metastasis were examined by univariate and multivariate statistical analyses. Results Fifty of 104 patients (48%) exhibited NSLN metastasis. Univariate and multivariate analyses revealed that tumor size and the ratio of positive SLNs were significant risk factors of NSLN metastasis in patients with a positive SLN. The rate of NSLN metastasis was higher in patients with luminal/HER2+ and HER2 overexpression subtypes than that in patients with other subtypes in the univariate analysis (p<0.001). In the multivariate analysis, both patients with luminal/HER2+ (p<0.006) and patients with HER2 overexpression (p<0.031) subtypes had a higher risk of NSLN metastasis than patients with the luminal A subtype. Conclusion Subtype classification should be considered as an independent factor when evaluating the risk of NSLN metastasis in patients with a positive SLN. This result supports the development of new nomograms including breast cancer subtype to increase predictive accuracy. PMID:25548586

    Purpose: The optimal number of axillary nodes to be resected is controversial. This large series investigated the effect of surgery with or without adjuvant radiotherapy among node-negative breast cancer patients in relation to the number of nodes examined. Methods and Materials: Node-negative patients from the Saskatchewan registry of 1981-1995 were studied. Because nodal status may be more reliable with more number of nodes examined, we analyzed T1-2 age < 90 patients with < 10 nodes examined treated with surgery alone (Group A{sub S}, n = 509) vs. surgery and adjuvant radiotherapy (Group A{sub S}+R, n = 342); and T1-2 age < 90 patients with {>=} 10 nodes examined treated with surgery alone (Group B{sub S}, n = 902) vs. surgery and adjuvant radiotherapy (Group B{sub S}+R, n = 596). Results: For the two radiotherapy groups, patients with < 10 nodes (Group A{sub S}+R) vs. {>=} 10 nodes (Group B{sub S}+R), there was no difference in overall survival (p = 0.14). In the two nonradiotherapy groups (A{sub S} and B{sub S}), there is a statistically significant decrease in overall survival for patients with < 10 nodes removed (p < 0.001, log-rank test). The optimal number of axillary nodes examined could be 8 nodes with adjuvant radiotherapy (p = 0.05, logrank test) and 12 nodes without adjuvant radiotherapy (p = 0.02, log-rank test). Conclusions: The poorer prognosis of a lesser number of nodes resected was overcome partly by the use of radiotherapy, raising the possibility of micrometastases in lymph nodes not removed. The optimal number of axillary nodes examined could be 8 nodes with adjuvant radiotherapy and 12 nodes without adjuvant radiotherapy.

    Intraoperative lymph scintigraphy during radical surgery for cervical cancer was developed in the course of a program covering three periods. During the last period technetium-99m antimony sulfide has been used to visualize pelvic lymph nodes. Surgery is done with a modified gamma camera serving as an operating table. This ensures intraoperative monitoring and greater thoroughness of lymphadenectomy. The introduction of the technique has improved the rate of total lymphadenectomies and has increased both the yields of involved nodes and the 3-yr survival rates.

    An 85 year male patient complaining epigastric discomfort was admitted. From the esophagogastroduodenoscopy, three early gastric cancer (EGCa) lesions had been identified and these were diagnosed as adenocarcinoma with poorly differentiated cell type. The patient underwent operation. From the post-operative mapping, however, additional 4 EGCa lesions were found, and the patient was diagnosed with 7 synchronous EGCa. Out of the 7 EGCa lesions, 6 had shown invasion only to the mucosal layer and one had shown invasion into the 1/3 layer of submucosa. In spite of such superficial invasions, 28 of 48 lymph nodes had been identified as metastases. The multiple lesions of EGCa do not increase the risk of lymph node metastasis, but if their differentiations are poor or if they have lympho-vascular invasion, multiple lymph node metastases could incur even if the depth of invasion is limited to the mucosal layer or the upper portion of the submucosal layer.

    The purpose of the present work was two-fold: 1) to evaluate the predictive value of the sentinel lymph node (sLN) versus the axillary-node status in patients with T1-T2 breast cancer, and 2) to form an experimental basis for a randomized trial in which one group of patients with non-metastatic sLN will not have axillary dissection. Of a group of 284 patients considered for this analysis, 264 had a T1 cancer (16 T1a, 37 T1b and 211 T1c), while 20 had a T2 cancer; 243 patients were in clinical stage N0 and 41 were N1. All patients underwent lymphoscintigraphy 18 hr before surgery: 10 MBq in 0.15 mL of 99mTc-human albumin nanocolloids (particle size between 50-80 nm) was injected subdermally at the cutaneous projection of the tumor. Static gamma-camera images were acquired every 10-15 minutes until scintigraphic identification of the sLN. At surgery, 1-2 mL of Patent-Blue Violet was injected subdermally, and the sLN was searched by gamma-probe and by the dye method. The surgically isolated sLN was processed for intraoperative Hematoxylin & Eosin (H&E) histology, then for delayed histological and immunohistochemical examinations. The sLN was successfully identified by the combined radioisotopic procedure and Patent-Blue dye technique in 278/284 cases (97.9%). The Patent-Blue dye technique alone identified fewer sLNs than the radioisotopic procedure alone (56.3% versus 97.2%). Analysis of the predictive value of the sLN as to the status of axillary lymph nodes was limited to 197 patients undergoing standard axillary dissection irrespective of the sLN status. Overall, 63/191 (33%) identified sLNs were metastatic, the sLN alone being involved in 37/63 (58.7%) patients; a positive axilla status with negative sLN was found in 10/73 patients with metastatic involvement (13.7% false-negative rate). In conclusion, subdermal lymphoscintigraphy was confirmed to be an effective technique for sLN mapping; the addition of Patent-Blue dye minimally improved intra-surgical identification of the sLN. There was a high, but not absolute, correlation between a negative sLN and a negative axilla. PMID:10941531

    The aim of Japanese Classification is to provide a common language for the clinical and pathological description of gastric cancer and thereby contribute to continued research and improvements in treatment and diagnosis. Lymph-node dissection has been regarded as an effective surgical treatment for gastric cancer in Japan. It reduces local recurrences and improves survival rate. Japanese-style systematic D2 lymphadenectomy is now being introduced in western countries for treatment of gastric cancer. This surgical procedure, however, is not simple and shoul be performed by experienced surgeons. And it is too early to apply sentinel node biopsy for reducing extent of lymphadenectomy because of so complicated lymphatic streams from the stomach and frequent skip- and micrometastases.

    Sentinel lymph nodes (SLN) are more likely to contain metastatic breast carcinoma than non-SLNs. The limited number of SLNs compared with an axillary dissection has prompted more comprehensive lymph node analysis increasing detection of micrometastases. National data show that many women previously classified node negative are now classified minimally node positive. As a result, our nodal classification and cancer staging have evolved to recognize the continuum of nodal tumor burden rather than a simplistic dichotomous stratification. It is quite clear that the more sections we evaluate from SLNs the more metastases we identify; however, it is impractical to expect the practicing pathologist to mount, stain, and microscopically examine every section through the SLN paraffin blocks. Despite recommendations from the College of American Pathologists and the American Society of Clinical Oncology, heterogeneity in the approach to SLN evaluation exists. What is needed is adherence to a standardized evaluation protocol. The most important aspect of the sentinel node examination is careful attention to slicing the SLN no thicker than 2.0 mm and correct embedding of the slices to assure we identify all macrometastases larger than 2.0 mm. A single section from blocks prepared in this manner will identify all macrometastases present but smaller metastases will be missed. The prognostic significance of these missed micrometastases is still being evaluated as we await SLN outcome studies. In the context of the new molecular classification of breast cancer, subgroups may be identified where detection of micrometastases has clinical significance. It is critical that both clinicians and pathologists understand there is a random component to micrometastasis distribution within the three-dimensional paraffin tissue blocks. If we ultimately adopt more comprehensive microscopic evaluation of SLNs, the candidate sampling strategies need to be carefully considered in the context of statistically valid sampling strategies.

    Axillary recurrence of breast cancer that involves the brachial neurovascular bundle is uncommon. However, for many patients with such recurrence, forequarter amputation can play a palliative role in relieving excruciating pain and paralysis of the upper limb. Further, for those patients who do not have distant metastasis or other local-regional recurrence, forequarter amputation provides a chance for a cure. Only a few case reports of curative amputations for recurrent breast cancer are present in the literature. Here, we report a case of forequarter amputation for curative treatment of axillary recurrent breast cancer, together with a literature review. To date, we have followed the patient for three years after amputation, during which there has been no evidence of recurrence or metastasis. Although radical resection is feasible, it can be accompanied by surgical wound complications and psychosocial stress. Therefore, an organized multidisciplinary approach is needed to ensure the success of radical resection. PMID:25407045

    Recently, the existence of lymph node micrometastasis (LNM), including isolated tumor cells, has been focused on during the development of molecular diagnostic tools for lymph node metastasis in various malignant neoplasms. In particular, immunohistochemistry and reverse transcription-polymerase chain reaction have been reported to be available for the detection of LNM in gastric cancer. However, at present, the clinical significance of LNM remains unclear in patients with gastric cancer. Therefore, we cannot strategically make light of this issue in clinical management. Currently, minimally invasive treatments, such as endoscopic submucosal dissection and laparoscopic surgery with personalized lymphadenectomy, are widely performed in consideration of postsurgical quality of life (QOL). However, it is important to maintain the balance between QOL and curability when selecting surgical treatments for patients with gastric cancer. If minimally invasive surgery based on LNM status was established for patients with early gastric cancer, it could be performed safely. We reviewed the clinical significance of LNM as an important strategic target in patients with gastric cancer. PMID:22546997

    We attempted to evaluate the history of sentinel node navigation surgery (SNNS), technical aspects, tracers, and clinical applications of SNNS using Infrared Ray Electronic Endoscopes (IREE) combined with Indocyanine Green (ICG). The sentinel lymph node (SLN) is defined as a first lymph node (LN) which receives cancer cells from a primary tumor. Reports on clinical application of SNNS for gastric cancers started to appear since early 2000s. Two prospective multicenter trials of SNNS for gastric cancer have also been accomplished in Japan. Kitagawa et al reported that the endoscopic dual (dye and radioisotope) tracer method for SN biopsy was confirmed acceptable and effective when applied to the early-stage gastric cancer (EGC). We have previously reported the usefulness of SNNS in gastrointestinal cancer using ICG as a tracer, combined with IREE (Olympus Optical, Tokyo, Japan) to detect SLN. LN metastasis rate of EGC is low. Hence, clinical application of SNNS for EGC might lead us to avoid unnecessary LN dissection, which could preserve the patient’s quality of life after operation. The most ideal method of SNNS should allow secure and accurate detection of SLN, and real time observation of lymphatic flow during operation. PMID:24914329

    To establish a series of objective parameters to predict the risk of relapse from axillary lymph node-negative (ANN) breast cancer, and evaluate the patterns of recurrence according to molecular subtypes, we collected information on 2126 consecutive breast cancer patients operated between 2002 and 2006. In this case-control study, 212 patients experiencing recurrence or breast cancer related death were defined as ‘poor group’. Another 212 patients were selected from the remaining cases with stratified sampling method to comprise the ‘good group’. Significant differences were found in vascular invasion, grade and molecular subtype between the two groups. Expression of ER and PR in the ‘poor group’ was lower (P < 0.05). However, positive rates of Ki67, p53 and VEGF in the ‘poor group’ were higher (P < 0.05). Multivariate analysis revealed that molecular subtype, expression of VEGF, tumor grade, and vascular invasion were closely correlated with bad outcome. Analysis of the ‘poor group’ demonstrated that ‘HER2 positive’ and ‘triple negative’ subtypes more commonly suffered from distant metastases and death. No metastasis was found in patients with pure invasive papillary carcinoma, invasive cribriform carcinoma or adenoid cystic carcinoma, whereas the diagnoses of invasive micropapillary carcinoma, invasive apocrine carcinoma, invasive papillary carcinoma mixed with invasive ductal carcinoma, or metaplastic carcinoma were correlated with distant metastasis and death. In conclusion, molecular subtype and expression of VEGF are useful markers for predicting prognosis of ANN breast cancer patients. ‘Luminal A-like’ subtype has better outcome than others. Moreover, molecular subtypes have different recurrence patterns. PMID:25031741

    Seroma formation is one of the most common complications following breast cancer surgery. It may lead to delay of adjuvant therapies and increasement of therapy costs. Bleomycin sulfate is a sclerosing antibiotic with antineoplastic efficacy. It is locally used in the treatment of pleural effusion. The present study aimed to investigate seroma-reducing effect of local bleomycin application after mastectomy. Sixteen female Wistar Albino rats were used in this study. The rats were divided into two equal groups. Under general anesthesia all rats underwent unilateral mastectomy as definition by Harada. Serum physiologic was applied to animals in Group 1 (control group) and bleomycin to Group 2. Mastectomized localization was explored on the 10th day postoperatively. Seroma and tissue samples were obtained from axilla and thoracic wall for histopathological examination. The amount of seroma was significantly lower in the bleomycin group as compared to the control group (P=0.002). Fibrosis, PNL infiltration and the number of fibroblasts were significantly higher in the bleomycin group. No difference was identified between the groups in terms of angiogenesis, edema, congestion, and monocyte, lymphocyte and macrophage infiltration. Local bleomycin sulfate application might be a therapeutic option in patients with seroma formation, as well as in the patients with malignant pleural effusion. Nonetheless, further studies that compare the efficacy and adverse effects (benefit-to-harm ratio) of bleomycin sulfate are needed. PMID:24231620

    Purpose: Katz suggested a nomogram for predicting having four or more positive nodes in sentinel lymph node (SLN)-positive breast cancer patients. The findings from this formula might influence adjuvant radiotherapy decisions. Our goal was to validate the accuracy of the Katz nomogram. Methods and Materials: We reviewed the records of 309 patients with breast cancer who had undergone completion axillary lymph node dissection. The factors associated with the likelihood of having four or more positive axillary nodes were evaluated in patients with one to three positive SLNs. The nomogram developed by Katz was applied to our data set. The area under the curve of the corresponding receiver operating characteristics curve was calculated for the nomogram. Results: Of the 309 patients, 80 (25.9%) had four or more positive axillary lymph nodes. On multivariate analysis, the number of positive SLNs (p < .0001), overall metastasis size (p = .019), primary tumor size (p = .0001), and extracapsular extension (p = .01) were significant factors predicting for four or more positive nodes. For patients with <5% probability, 90.3% had fewer than four positive nodes and 9.7% had four or more positive nodes. The negative predictive value was 91.7%, and sensitivity was 80%. The nomogram was accurate and discriminating (area under the curve, .801). Conclusion: The probability of four or more involved nodes is significantly greater in patients who have an increased number of positive SLNs, increased overall metastasis size, increased tumor size, and extracapsular extension. The Katz nomogram was validated in our patients. This nomogram will be helpful to clinicians making adjuvant treatment recommendations to their patients.

  4. Mayo Clinic study finds less invasive surgery detects residual breast cancer in lymph nodes after chemotherapy

    Cancer.gov

    Most patients whose breast cancer has spread to their lymph nodes have most of the lymph nodes in their armpit area removed after chemotherapy to see if any cancer remains. A study conducted through the American College of Surgeons Oncology Group and led by the Mayo Clinic shows that a less invasive procedure known as sentinel lymph node surgery successfully identified whether cancer remained in lymph nodes in 91 percent of patients with node-positive breast cancer who received chemotherapy before their surgery. In sentinel lymph node surgery, only a few lymph nodes, the ones most likely to contain cancer, are removed. The findings are being presented at the 2012 CTRC-AACR San Antonio Breast Cancer Symposium.

    The prognostic significance of identifying lymph node (LN) metastases following surgical resection for colon and rectal cancer is well recognized and is reflected in accurate staging of the disease. An established body of evidence exists, demonstrating an association between a higher total LN count and improved survival, particularly for node negative colon cancer. In node positive disease, however, the lymph node ratios may represent a better prognostic indicator, although the impact of this on clinical treatment has yet to be universally established. By extension, strategies to increase surgical node harvest and/or laboratory methods to increase LN yield seem logical and might improve cancer staging. However, debate prevails as to whether or not these extrapolations are clinically relevant, particularly when very high LN counts are sought. Current guidelines recommend a minimum of 12 nodes harvested as the standard of care, yet the evidence for such is questionable as it is unclear whether an increasing the LN count results in improved survival. Findings from modern treatments, including down-staging in rectal cancer using pre-operative chemoradiotherapy, paradoxically suggest that lower LN count, or indeed complete absence of LNs, are associated with improved survival; implying that using a specific number of LNs harvested as a measure of surgical quality is not always appropriate. The pursuit of a sufficient LN harvest represents good clinical practice; however, recent evidence shows that the exhaustive searching for very high LN yields may be unnecessary and has little influence on modern approaches to treatment.

    Background: Sentinel lymph node biopsy (SLNB) is standard care to evaluate axillary involvement in early breast cancer. It has fewer complications than complete lymph node dissection; however, using blue dye in SLNB is controversial. We have evaluated the detection rate and local complications associated with methylene blue dye (MBD) used in SLNB in early breast cancer patients and compared these results to patent blue dye (PBD). Materials and Methods: In a cohort prospective study, 312 patients with early breast cancer without axillary lymph node involvement were divided into two groups according to dye type. All of the patients received radiotracer and one type of blue dye. We filled out a checklist for the patients that contained demographic data, size of tumor, stage, detection of sentinel lymph node, and complications and then analyzed the data. Results: Demographic and histopathologic characteristics were not significantly different in both groups. Mean (standard deviation [SD]) tumor size in all patients was 2.4 (0.8) cm. Detection rate in the MBD group was 77.5% with dye alone and 94.2% with dye and radioisotope; and in the PBD group it was 80.1% and 92.9% respectively (P > 0.05). We had blue discoloration of the skin in 23.7% in the PBD and 14.1% in the MBD group (P < 0.05) local inflammation was detected in one patient in the PBD and five in the MBD group (P < 0.05). Skin necrosis and systemic complications were not observed. Conclusion: Methylene blue has an acceptable detection rate, which may be a good alternative in SLNB. Complication such as blue discoloration of the skin was also lower with MBD. PMID:25538772

    Recently, lymph node micrometastasis has been evaluated for its prognostic value in gastric cancer. Lymph node micrometastasis cannot be detected via a usual pathologic examination, but it can be detected by using some other techniques including immunohistochemistry and reverse transcription-polymerase chain reaction assay. With the development of such diagnostic techniques, the detection rate of lymph node micrometastasis is constantly increasing. Although the prognostic value of lymph node micrometastasis remains debatable, its clinical impact is apparently remarkable in both early and advanced gastric cancer. At present, studies on the prognostic value of lymph node micrometastasis are evolving to overcome its current limitations and extend the scope of its application. PMID:25861517

    Background. Lymphedema secondary to breast cancer treatment is a common and serious problem for disease survivors. The objective of the current study was to identify the risk factors of secondary lymphedema after breast carcinoma treatment. Materials & Methods. The breast cancer patients who were followed up in three centers in Tehran and Mashhad in 2010 were recruited in the study. The circumference measurement was used for defining lymphedema. Results. Among 410 breast cancer patients, 123 cases (30%) developed lymphedema. Variables such as low educational level, body mass index (BMI), higher stage of disease, number of involved lymph nodes, comorbid diseases, trauma, infection, and the time after surgery showed significant correlation with the development of lymphedema. In logistic regression analysis, increase of 1?kg/m2 in BMI (OR?=?1.09; 95%??CI 1.05–1.15), each number increase in lymph node involvement (OR?=?1.15; 95%??CI 1.08–1.21) and the increase of every 1 month after surgery (OR?=?1.01; 95%??CI 1.01–1.02) significantly increased the risk of lymphedema. Conclusion. The results of this study demonstrated that preserving a fitted BMI, emphasis on self-care, and educating preventive activities may have important roles in decreasing the lymphedema incidence and improving the patients' quality of life.

    This study aimed to characterize lymph node metastasis and determine its clinical significance in the surgical treatment of gastric cancer. The medical charts of 920 gastric cancer patients who underwent radical surgical resection between March, 2010 and March, 2013, were retrospectively reviewed and statistically analyzed. Lymphatic metastasis was observed in 69.6% of the patients (640/920). The frequency of lymph node metastasis in patients with early-stage gastric cancer was 21.4% (18/84). Lymph node metastasis was observed in all the patients with stage IIIC-IV gastric cancer. The incidence of lymph node metastasis was higher among patients with tumors >7 cm in size. The most frequently affected lymph nodes in patients with proximal, central and distal gastric cancer were station no. 1 (34.2%), no. 3 (33.8%) and no. 6 (34.3%) lymph nodes, respectively. The frequency of lymph node metastasis in patients with Borrmann type IV cancer was significantly higher compared to that in patients with other Borrmann type cancers. Our study further demonstrated that lymphatic metastasis is closely correlated with TNM stage, location, depth of invasion and size of gastric tumors. Therefore, we recommend that a sufficient number of lymph nodes be examined from each patient to determine the extent of lymph node dissection based on Borrmann type, location, size, depth of invasion and histology of the cancer.

    Background Lymph node invasion is one of the most powerful clinical factors in cancer prognosis. However, molecular level signatures of their correlation are remaining poorly understood. Here, we propose a new approach, monotonically expressed gene analysis (MEGA), to correlate transcriptional patterns of lymph node invasion related genes with clinical outcome of breast cancer patients. Results Using MEGA, we scored all genes with their transcriptional patterns over progression levels of lymph node invasion from 278 non-metastatic breast cancer samples. Applied on 65 independent test data, our gene sets of top 20 scores (positive and negative correlations) showed significant associations with prognostic measures such as cancer metastasis, relapse and survival. Our method showed better accuracy than conventional two class comparison methods. We could also find that expression patterns of some genes are strongly associated with stage transition of pathological T and N at specific time. Additionally, some pathways including T-cell immune response and wound healing serum response are expected to be related with cancer progression from pathway enrichment and common motif binding site analyses of the inferred gene sets. Conclusions By applying MEGA, we can find possible molecular links between lymph node invasion and cancer prognosis in human breast cancer, supported by evidences of feasible gene expression patterns and significant results of meta-analysis tests.

    Between January, 1967 and July, 1980, 176 women who were referred to the Joint Center for Radiation Therapy (JCRT) for definitive breast irradiation underwent low axillary dissection. A typical operative technique is described. The dissection stops short of the axillary vein although the vein is usually visualized. One hundred thirty-two axillae were thought to be N/sub 0/ or N/sub 1a/. Forty-six axillae were felt to be N/sub 1b/. Seventeen percent of the T/sub 1/ N/sub 0/ patients had pathologically positive nodes. Twenty-seven percent of the T/sub 2/ N/sub 0/ patients had positive nodes. When 5 or less nodes were removed at axillary sampling the incidence of nodal involvement was very low. There were no differences in nodal positivity when comparing under quadrant to lower or central lesions. Ninety-four percent of axillae with N/sub 1b/ lesions were pathologically confirmed. The complication rate for this procedure was low. There was 5 transient non-surgical complications and 1 cellulitis resulting in a frozen shoulder, which required corrective surgery. There were no cases of moderate or severe arm edema. Axillary sampling is compared to axillary dissection as a diagnostic procedure. Axillary sampling may underestimate the true pathologic positive rate, but diagnostic accuracy appears excellent if level 1 and 2 nodes are sampled.

    Between 1982 and 1990, 321 elderly patients (range 70-92 years, median age 77) with operable breast cancer (T1 in 219, T2 in 77, T3 in one and T4b in 24 patients) and clinically uninvolved axillary nodes underwent surgery without axillary dissection and received adjuvant tamoxifen. All patients had surgery performed under local anaesthesia. Tamoxifen was given after surgery at the dose of 20 mg daily, indefinitely. With a median follow-up of 67 months (range 42-141), 17 patients developed local relapse, 14 ipsilateral axillary recurrence, five ipsilateral breast cancer, five contralateral breast cancer, 13 second primary and 23 developed distant metastases. The cumulative probability of developing a local, axillary and distant recurrence at 72 months was estimated to be 5.4%, 4.3% and 6.2%, respectively. Out of 244 patients who did not develop any relapse, 83 (25.8%) died from intercurrent disease. The 72 month relapse-free survival rate was 76%. This experience suggests that elderly patients with small tumours without clinical axillary involvement may be satisfactorily treated with conservative surgery and tamoxifen. The importance of axillary dissection is controversial owing to a high response rate to hormonal therapy and an increased death rate due to concomitant diseases. PMID:7577477

    Mediastinal lymph node metastasis from colorectal cancer is rare, and barely any reports have described resection of this pathology. We report herein a successful thoracoscopic resection of mediastinal lymph node metastasis in a prone position. A 65-year-old man presented with posterior mediastinal lymph node metastasis after resection of the primary rectal cancer and metachronous hepatic metastasis. Metastatic lymph nodes were resected completely using thoracoscopic surgery in the prone position, which provided advantages of minimal invasiveness, good surgical field, and reduced ergonomic burden on the surgeon. Thoracoscopic resection in the prone position was thought to have the potential to become the standard procedure of posterior mediastinal tumors. PMID:25778039

    Outcome prediction based on tumor stage reflected by the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) tumor node metastasis (TNM) system is currently regarded as the strongest prognostic parameter for patients with colorectal cancer. For affected patients, the indication for adjuvant therapy is mainly guided by the presence of regional lymph node metastasis. In addition to the extent of surgical lymph node removal and the thoroughness of the pathologist in dissecting the resection specimen, several parameters that are related to the pathological work-up of the dissected nodes may affect the clinical significance of lymph node staging. These include changing definitions of lymph nodes, involved lymph nodes, and tumor deposits in different editions of the AJCC/UICC TNM system as well as the minimum number of nodes to be dissected. Methods to increase the lymph node yield in the fatty tissue include methylene blue injection and acetone compression. Outcome prediction based on the lymph node ratio, defined as the number of positive lymph nodes divided by the total number of retrieved nodes, may be superior to the absolute numbers of involved nodes. Extracapsular invasion has been identified as additional prognostic factor. Adding step sectioning and immunohistochemistry to the pathological work-up may result in higher accuracy of histological diagnosis. The clinical value of more recent technical advances, such as sentinel lymph node biopsy and molecular analysis of lymph nodes tissue still remains to be defined. PMID:24379568

    Importance Sentinel lymph node (SLN) surgery provides reliable nodal staging information with less morbidity than axillary lymph node dissection (ALND) for clinically node-negative (cN0) breast cancer patients. The application of SLN surgery for staging the axilla following chemotherapy for women who initially had node-positive breast cancer (cN1) is unclear because of high false negative results reported in previous studies. Objective To determine the false negative rate (FNR) for SLN surgery following chemotherapy in patients initially presenting with biopsy-proven node-positive breast cancer. Design, Setting, and Patients The ACOSOG Z1071 trial enrolled women with clinical T0–4 N1–2, M0 breast cancer who received neoadjuvant chemotherapy. Following chemotherapy, patients underwent both SLN surgery and ALND. SLN surgery using both blue dye and a radiolabeled colloid mapping agent was encouraged. Main Outcome Measure The primary endpoint was the FNR of SLN surgery after chemotherapy in women who presented with cN1 disease. We examined the likelihood that the FNR in those with 2 or more SLNs examined was greater than 10%, the rate expected for women undergoing SLN surgery who present with clinically node-negative disease. Results Seven hundred fifty-six patients were enrolled from 136 institutions. Of 663 evaluable patients with cN1 disease, 649 underwent chemotherapy followed by both SLN surgery and ALND. A SLN could not be identified in 46 patients (7.1%). Only one SLN was excised in 78 patients (12.0%). Of the remaining 525 patients with 2 or more SLNs removed, no cancer was identified in the axillary lymph nodes of 215 patients yielding a pathological complete nodal response of 41.0% (95% CI: 36.7%–45.3%). In 39 patients, cancer was not identified in the SLNs but was found in lymph nodes obtained with ALND resulting in a FNR of 12.6% (90% Bayesian Credible Interval, 9.85%–16.05%). Conclusions and Relevance Among women with cN1 breast cancer receiving neoadjuvant chemotherapy who had 2 or more SLNs examined, the FNR was not found to be 10% or less. Given this FNR threshold, changes in approach and patient selection that result in greater sensitivity would be necessary to support the use of SLN surgery as an alternative to ALND.

    Background Current practice is to perform a completion axillary lymph node dissection (ALND) for breast cancer patients with tumor-involved sentinel lymph nodes (SLNs), although fewer than half will have non-sentinel node (NSLN) metastasis. Our goal was to develop new models to quantify the risk of NSLN metastasis in SLN-positive patients and to compare predictive capabilities to another widely used model. Methods We constructed three models to predict NSLN status: recursive partitioning with receiver operating characteristic curves (RP-ROC), boosted Classification and Regression Trees (CART), and multivariate logistic regression (MLR) informed by CART. Data were compiled from a multicenter Northern California and Oregon database of 784 patients who prospectively underwent SLN biopsy and completion ALND. We compared the predictive abilities of our best model and the Memorial Sloan-Kettering Breast Cancer Nomogram (Nomogram) in our dataset and an independent dataset from Northwestern University. Results 285 patients had positive SLNs, of which 213 had known angiolymphatic invasion status and 171 had complete pathologic data including hormone receptor status. 264 (93%) patients had limited SLN disease (micrometastasis, 70%, or isolated tumor cells, 23%). 101 (35%) of all SLN-positive patients had tumor-involved NSLNs. Three variables (tumor size, angiolymphatic invasion, and SLN metastasis size) predicted risk in all our models. RP-ROC and boosted CART stratified patients into four risk levels. MLR informed by CART was most accurate. Using two composite predictors calculated from three variables, MLR informed by CART was more accurate than the Nomogram computed using eight predictors. In our dataset, area under ROC curve (AUC) was 0.83/0.85 for MLR (n = 213/n = 171) and 0.77 for Nomogram (n = 171). When applied to an independent dataset (n = 77), AUC was 0.74 for our model and 0.62 for Nomogram. The composite predictors in our model were the product of angiolymphatic invasion and size of SLN metastasis, and the product of tumor size and square of SLN metastasis size. Conclusion We present a new model developed from a community-based SLN database that uses only three rather than eight variables to achieve higher accuracy than the Nomogram for predicting NSLN status in two different datasets.

    Colorectal cancer guidelines recommend adjuvant chemotherapy in stage II disease when less than 12 lymph nodes are assessed. The recommendation bases on previous studies showing an association of a low lymph node count and adverse outcome. Compared to current standards, however, the quality of lymph node examination in the studies was low. We, therefore, investigated the prognostic role of <12 lymph nodes in cancers diagnosed adherent to current quality measures. Stage I-IV colorectal cancers from 1,899 patients enrolled into a population-based cohort study were investigated for the prognostic impact of a lymph node count <12. The stage specific share of patients diagnosed with ?12 nodes (stage I-IV: 62, 85, 85, 78%, respectively) was used to compare lymph node examination quality to other studies. We found no impact of a lymph node count <12 on overall, cancer-specific or recurrence-free survival for any tumour stage. Compared to studies reporting an adverse prognostic impact of a low lymph node count in stages II and III the stage-specific shares of patients with ?12 nodes were markedly higher in this study (85% vs. 24-58% in previous analyses) and this correlated with increased rates of stage III compared to stage II cancers. In conclusion our data indicate, that the previously reported effect of a low lymph node count on the patients' outcomes is eliminated by improved lymph node examination quality and thus question the general applicability of a 12 lymph node cut off for adjuvant chemotherapy decision making in stage II disease.

    Currently, early gastrointestinal cancers are treated endoscopically, as long as there are no lymph node metastases. However, once a gastrointestinal cancer invades the submucosal layer, the lymph node metastatic rate rises to higher than 10%. Therefore, surgery is still the gold standard to remove regional lymph nodes containing possible metastases. Here, to avoid prophylactic surgery, we propose a less-invasive biological ablation of lymph node metastasis in submucosally invaded gastrointestinal cancer patients. We have established an orthotopic early rectal cancer xenograft model with spontaneous lymph node metastasis by implantation of green fluorescent protein (GFP)-labeled human colon cancer cells into the submucosal layer of the murine rectum. A solution containing telomerase-specific oncolytic adenovirus was injected into the peritumoral submucosal space, followed by excision of the primary rectal tumors mimicking the endoscopic submucosal dissection (ESD) technique. Seven days after treatment, GFP signals had completely disappeared indicating that sentinel lymph node metastasis was selectively eradicated. Moreover, biologically treated mice were confirmed to be relapse-free even 4 weeks after treatment. These results indicate that virus-mediated biological ablation selectively targets lymph node metastasis and provides a potential alternative to surgery for submucosal invasive gastrointestinal cancer patients.

    Purpose: The development of breast cancer-related lymphedema (LE) is closely related to the number of dissected axillary lymph nodes (N-ALNs), chemotherapy, and radiation therapy. In this study, we attempted to estimate the risk of LE based on combinations of these treatment-related factors. Methods and Materials: A total of 772 patients with breast cancer, who underwent primary surgery with axillary lymph node dissection from 2004 to 2009, were retrospectively analyzed. Adjuvant chemotherapy (ACT) was performed in 677 patients (88%). Among patients who received radiation therapy (n=675), 274 (35%) received supraclavicular radiation therapy (SCRT). Results: At a median follow-up of 5.1 years (range, 3.0-8.3 years), 127 patients had developed LE. The overall 5-year cumulative incidence of LE was 17%. Among the 127 affected patients, LE occurred within 2 years after surgery in 97 (76%) and within 3 years in 115 (91%) patients. Multivariate analysis showed that N-ALN (hazard ratio [HR], 2.81; P<.001), ACT (HR, 4.14; P=.048), and SCRT (HR, 3.24; P<.001) were independent risk factors for LE. The total number of risk factors correlated well with the incidence of LE. Patients with no risk or 1 risk factor showed a significantly lower 5-year probability of LE (3%) than patients with 2 (19%) or 3 risk factors (38%) (P<.001). Conclusions: The risk factors associated with LE were N-ALN, ACT, and SCRT. A simple model using combinations of these factors may help clinicians predict the risk of LE.

    The axillary staging in newly diagnosed breast cancer is under major evolution. The aims of this study were to define the diagnostic performance of 3.0-T diffusion-weighted imaging (DWI) in the detection of axillary metastases in newly diagnosed breast cancer, to assess apparent diffusion coefficients (ADCs) for histopathologically confirmed metastatic lymph nodes in a clinical setting. Altogether 52 consecutive breast cancer patients underwent magnetic resonance imaging and DWI in addition to axillary ultrasound. ADCs of axillary lymph nodes were analysed by two breast radiologists and ultrasound-guided core biopsies were taken. In a separate reading by one radiologist two types of region of interests were used for a smaller group of patients. Altogether 56 axillae (121 lymph nodes) were included in the statistical analysis. Metastatic axillae (51.8%) had significantly lower ADCs (p<0.001). Mean ADCs were 0.663–0.676 x 10-3 mm2/s for the histologically confirmed metastatic LNs and 1.100–1.225 x 10-3 mm2/s for the benign. The sensitivity, specificity, and accuracy of DWI were 72.4%, 79.6%, and 75.9%, respectively with threshold ADC 0.812 x 10-3 mm2/s. Region of interest with information on the minimum value increased the diagnostic performance (area under the curve 0.794 vs. 0.619). Even though ADCs are significantly associated with histopathologically confirmed axillary metastases the diagnostic performance of axillary DWI remains moderate and ultrasound-guided core biopsies or sentinel lymph node biopsies cannot be omitted.

    Summary Background If treatment of the axilla is indicated in patients with breast cancer who have a positive sentinel node, axillary lymph node dissection is the present standard. Although axillary lymph node dissection provides excellent regional control, it is associated with harmful side-effects. We aimed to assess whether axillary radiotherapy provides comparable regional control with fewer side-effects. Methods Patients with T1–2 primary breast cancer and no palpable lymphadenopathy were enrolled in the randomised, multicentre, open-label, phase 3 non-inferiority EORTC 10981-22023 AMAROS trial. Patients were randomly assigned (1:1) by a computer-generated allocation schedule to receive either axillary lymph node dissection or axillary radiotherapy in case of a positive sentinel node, stratified by institution. The primary endpoint was non-inferiority of 5-year axillary recurrence, considered to be not more than 4% for the axillary radiotherapy group compared with an expected 2% in the axillary lymph node dissection group. Analyses were by intention to treat and per protocol. The AMAROS trial is registered with ClinicalTrials.gov, number NCT00014612. Findings Between Feb 19, 2001, and April 29, 2010, 4823 patients were enrolled at 34 centres from nine European countries, of whom 4806 were eligible for randomisation. 2402 patients were randomly assigned to receive axillary lymph node dissection and 2404 to receive axillary radiotherapy. Of the 1425 patients with a positive sentinel node, 744 had been randomly assigned to axillary lymph node dissection and 681 to axillary radiotherapy; these patients constituted the intention-to-treat population. Median follow-up was 6·1 years (IQR 4·1–8·0) for the patients with positive sentinel lymph nodes. In the axillary lymph node dissection group, 220 (33%) of 672 patients who underwent axillary lymph node dissection had additional positive nodes. Axillary recurrence occurred in four of 744 patients in the axillary lymph node dissection group and seven of 681 in the axillary radiotherapy group. 5-year axillary recurrence was 0·43% (95% CI 0·00–0·92) after axillary lymph node dissection versus 1·19% (0·31–2·08) after axillary radiotherapy. The planned non-inferiority test was underpowered because of the low number of events. The one-sided 95% CI for the underpowered non-inferiority test on the hazard ratio was 0·00–5·27, with a non-inferiority margin of 2. Lymphoedema in the ipsilateral arm was noted significantly more often after axillary lymph node dissection than after axillary radiotherapy at 1 year, 3 years, and 5 years. Interpretation Axillary lymph node dissection and axillary radiotherapy after a positive sentinel node provide excellent and comparable axillary control for patients with T1–2 primary breast cancer and no palpable lymphadenopathy. Axillary radiotherapy results in significantly less morbidity. Funding EORTC Charitable Trust. PMID:25439688

    Sentinel lymph node biopsy (SLNB) completely changed the impact of breast surgery on patients psycho-physical wellness, reducing morbidity associated with complete axillary lymph node dissection (CALND) while granting an adequate breast cancer staging. We reviewed our experience with the SLNB in a University Clinic. We collected data about all breast cancer patients submitted to SLNB from 2002 to 2010, and analyzed them with R (version 2.15.2), considering significant p<0.05. We performed 615 SLNBs on 607 patients, with a mean age of 59.86 (±10.76). Sentinel node detection rate resulted 99,7%, with a mean number of biopsied nodes of 1.64 (±0.67), axillary localization in 98% of cases, and negative intraoperative histological finding in the 86.2% of cases. Prevalence of ITCs, micrometastasis, macrometastasis and pericapsular metastasis resulted respectively 0.6%, 4.9%, 7.5% and 8.8%. Among women who received CALND, mean number of examined nodes was 16.36 (±6.19) and mean number of metastatic non-sentinel nodes was 0.97 in case of micrometastasis, 2.65 in case of macrometastasis, and up to 9.88 when pericapsular invasion was described. To conclude, our data confirm the role of nodal metastasis size in the prediction of non-sentinel node involvement, but further studies are required in order to better assess the role of ITCs and micrometastasis in the diagnostic and therapeutic management of breast cancer, with the final aim to reduce the surgical complications of axilla demolition when unnecessary.

    Introduction: The successful treatment of prostate cancer depends on the accurate estimation of the risk of regional lymph node (LN) involvement. The Roach formula (RF) has been criticized as overestimating LN risk. A modification of the RF has been attempted by other investigators using simplified adjustment ratios: the Nguyen formula (NF). Methods and Materials: The National Cancer Institute Surveillance, Epidemiology, and End Results database was investigated for patients treated in 2004 through 2006 for whom at least 10 LN were examined at radical prostatectomy, cT1c or cT2 disease, and prostate-specific antigen (PSA) <26 ng/ml (N = 2,930). The Yale formula (YF) was derived from half of the sample (n = 1,460), and validated in the other half (n = 1,470). Results: We identified 2,930 patients. Only 4.6% of patients had LN+, and 72.6% had cT1c disease. Gleason (GS) 8-10 histology was found in 14.4% of patients. The YF for prediction of %LN+ risk is [GS - 5]x [PSA/3 + 1.5 x T], where T = 0, 1, and 2 for cT1c, cT2a, and cT2b/cT2c. Within each strata of predicted %LN+ risk, the actual %LN+ was closest to the YF. Using a >15% risk as an indicator of high-risk disease, the YF had increased sensitivity (39.0% vs. 13.6%) compared with the NF, without a significant reduction in specificity (94.9% vs. 98.8%). The NF was overly restrictive of the high-risk group, with only 2% of patients having a >15% risk of LN+ by that formula. Conclusion: The YF performed better than the RF and NF and was best at differentiating patients at high risk for LN+ disease.

    Adding a taxane to anthracycline-based adjuvant chemotherapy prolongs survival in node-positive early breast cancer. However, which is the preferable taxane in a dose-dense regimen remains unknown. We conducted a randomized study to compare the efficacy of dose-dense paclitaxel versus docetaxel following 5-fluorouracil, epirubicin, and cyclophosphamide (FEC) as adjuvant chemotherapy in women with node-positive early breast cancer. Following surgery women with HER2-negative breast cancer and at least one infiltrated axillary lymph node were randomized to receive four cycles of FEC (700/75/700 mg/m(2)) followed by four cycles of either paclitaxel (175 mg/m(2)) or docetaxel (75 mg/m(2)). All cycles were administered every 14 days with G-CSF support. The primary endpoint was disease-free survival (DFS) at 3 years. Between 2004 and 2007, 481 women were randomized to paclitaxel (n = 241) and docetaxel (n = 240). After a median follow-up of 6 years, 51 (21%) and 48 (20%) women experienced disease relapse (p = 0.753) and there was no significant difference in DFS between the paclitaxel- and docetaxel-treated groups (3-year DFS 87.4 vs. 88.3%, respectively; median DFS not reached; p = 0.633). Toxicities were manageable, with grade 2-4 neutropenia in 21 versus 31% (p = 0.01), thrombocytopenia 0.8 versus 3.4% (p = 0.06), any grade neurotoxicity 17 versus 7.5% (p = 0.35) and onycholysis 4.9 versus 12.1% (p = 0.03) for patients receiving paclitaxel and docetaxel, respectively. There were no toxic deaths. Dose-dense paclitaxel versus docetaxel after FEC as adjuvant chemotherapy results in a similar 3-year DFS rate in women with axillary node-positive early breast cancer. Due to its more favorable toxicity profile, paclitaxel is the taxane of choice in this setting. PMID:25399229

    AIM: To assess the role of computed tomography (CT) and magnetic resonance imaging (MRI) and establish imaging criteria of lymph node metastasis in early colorectal cancer. METHODS: One hundred and sixty patients with early colorectal cancer were evaluated for tumor location, clinical history of polypectomy, depth of tumor invasion, and lymph node metastasis. Two radiologists assessed preoperative CT and/or MRI for the primary tumor site detectability, the presence or absence of regional lymph node, and the size of the largest lymph node. Demographic, imaging, and pathologic findings were compared between the two groups of patients based on pathologic lymph node metastasis and optimal size criterion was obtained. RESULTS: The locations of tumor were ascending, transverse, descending, sigmoid colon, and rectum. One hundred and sixty early colorectal cancers were classified into 3 groups based on the pathological depth of tumor invasion; mucosa, submucosa, and depth unavailable. A total of 20 (12.5%) cancers with submucosal invasion showed lymph node metastasis. Lymph nodes were detected on CT or MRI in 53 patients. The detection rate and size of lymph nodes were significantly higher (P = 0.000, P = 0.044, respectively) in patients with pathologic nodal metastasis than in patients without nodal metastasis. Receiver operating curve analysis showed that a cut-off value of 4.1 mm is optimal with a sensitivity of 78.6% and specificity of 75%. CONCLUSION: The short diameter size criterion of ? 4.1 mm for metastatic lymph nodes was optimal for nodal staging in early colorectal cancer. PMID:25593474

    Purpose Near-infrared fluorescence imaging with indocyanine green (ICG) has the potential to improve sentinel lymph node (SLN) mapping in breast cancer. In this clinical trial, we compared the potential value of ICG combined with blue dye with that of blue dye alone for detecting SLNs. Methods Patients undergoing SLN biopsy (SLNB) between November 2010 and November 2013 were included. Up to December 2011, SLNs were detected by using patent blue (PB) alone, and since January 2012, by using PB in combination with ICG. The patients were divided into the following two groups: group A (ICG-PB; n=96) and group B (PB; n=73), and SLN detection parameters were compared between the groups. All patients underwent level I and II axillary dissections after SLNB. Results In group A, the SLN detection rate was 96.9% (93/96), the accuracy of detection was 98.9% (92/93), and the false-negative rate (FNR) was 3.4% (1/29). In group B, the SLN detection rate was 84.9% (62/73), the accuracy of detection was 96.8% (60/62), and the FNR was 11.1% (2/18). The ICG-PB group showed significantly superior results compared to the PB group for SLN detection (p=0.005) and a greatly improved FNR. Conclusion The combined fluorescence and blue dye-based tracer technique was superior to the use of blue dye alone for identifying SLNs, and for predicting axillary lymph node status in patients with breast cancer; in addition, the combined technique had reduced false-negative results.

    Video-assisted thoracoscopic surgery (VATS) represents a new trend in the development of minimally invasive thoracic surgery. When applied in lung cancer surgeries, VATS can be used for both pulmonary lobectomy and regional lymph node dissection. Currently the main concerns are focused on the completeness of lymph node dissection for lung cancer and the safety of surgery. The lymph node dissection includes two parts: (I) dissection of interlobar and hilar lymph nodes; and (II) dissection of mediastinal lymph nodes. The demonstrated surgical procedures are featured by: (I) the interlobar and hilar lymph nodes are not removed separately; rathr, they are taken out en bloc with the pulmonary lobes during the surgery; and (II) systematic lymph node dissection, instead of systematic sampling, is applied for the removal of mediastinal lymph nodes. Also, during the fully anatomical resection, each blood vessel and bronchus underwent anatomical dissociation, indicating that this surgery is safe. PMID:24040542

    The necessity of pelvic lymph node dissection has been questioned in recent years as a result of improved pre-treatment staging based on clinical and pathologic factors. Accurate evaluation of nodal status allows rational selection of therapy and improved outcomes. Nevertheless, lymph node dissection may play a role even in patients with low stage disease (clinical T1c) despite an overall low risk for metastases. Herein we discuss recent advances in the evaluation of lymph nodes in stage T1c prostate cancer with respect to accurate prediction, radiologic imaging, molecular characterization, and operative considerations.

    Radical lymph node dissection provides survival benefit for patients with pT2 or more advanced gallbladder carcinoma tumors only if potentially curative resection is feasible; it must always be considered when planning a resection or re-resection for robust patients with pT2 or more advanced gallbladder carcinoma tumors. The degree of radical lymphadenectomy depends on clinically assessed nodal status: portal lymph node dissection is limited to cN0 disease; extended portal nodal dissection is indicated for cN0 and a modest degree of cN1 disease; peripancreatic lymph node dissection with pancreaticoduodenectomy is indicated for selected cases of evident peripancreatic nodal disease and/or direct organ involvement. Extended resection with extensive lymphadenectomy should be limited to expert surgeons because it may cause serious morbidity and mortality. PMID:17336245

    The synchronous occurrence of tuberculosis and carcinoma in breast is unusual. The simultaneous occurrence of both the diseases can complicate the neoplastic disease. The diagnosis and treatment of tuberculosis in a patient with cancer assumes importance as it can prevent high mortality in patients with co-existent disease and thereby create problems in treatment decision. Axillary lymph node enlargement in breast cancer patient is not always caused by metastatic tumour of the breast even in the ipsilateral axillary nodes. We present here six case reports as an example of tuberculous axillary lymphadenitis co-existing with invasive ductal carcinoma of the breast. Accurate diagnosis has helped in down-staging carcinoma of the breast and also in identifying curable disease. PMID:21114180

That has put the gastric cancer on 5th place in frequency, and on 3th placeas leading cause of death in both sexes in the world--723,000 fatalities or 8.8% of all. According to the data of the World Health Organization, in 2005 Bulgaria was on 23rd place in absolute number of gastric cancer deaths among the men and on 25th place among the women. In 2011, we were on 11th place in absolute number of gastric cancer deaths among the men and on 12th place among the women. According to NCCN (National Comprehensive Cancer Network) there are 2 basic types of surgical interventions that are used for radical gastric cancer treatment- total and subtotal gastrectomy. The scientific society however is still divided on the matter of the volume of lymph dissection. The gastrectomy with D2 lymph dissection is the standard treatment for resectable gastric carcinoma in Asia. In the Western countries, the D2 lymph dissection is considered an advisable, but not mandatory procedure. Despite that, there is a rule that the removal of more than 15 lymph nodes is in favor of the NCCN. Nowadays in Japan the comparative studies between D1 and D2 gastrectomy are considered unethical.

    Purpose: To prospectively determine the effect of deodorant use on acute skin toxicity and quality of life during breast radiotherapy (RT). Methods and Materials: Before breast RT, 84 patients were randomly assigned to the deodorant group (n = 40) or the no-deodorant group (n = 44). The patients were stratified by axillary RT and previous chemotherapy. Toxicity evaluations were always performed by the principal investigator, who was unaware of the group assignment, at the end of RT and 2 weeks after completion using the Radiation Therapy Oncology Group acute skin toxicity criteria. Symptoms of acute skin toxicity (i.e., discomfort, pain, pruritus, sweating) and quality of life were self-evaluated. For each criterion, the point estimate of rate difference with the 95% one-sided upper confidence limit was computed. To claim noninferiority owing to deodorant use, the 95% one-sided upper confidence limit had to be lower than the noninferiority margin, fixed to 12.8%. Results: In the deodorant vs. no-deodorant groups, Grade 2 axillary radiodermatitis occurred in 23% vs. 30%, respectively, satisfying the statistical criteria for noninferiority (p = .019). Grade 2 breast radiodermatitis occurred in 30% vs. 34% of the deodorant vs. no-deodorant groups, respectively, also satisfying the statistical criteria for noninferiority (p = .049). Similar results were observed for the self-reported evaluations. The deodorant group reported less sweating (18% vs. 39%, p = .032). No Grade 3 or 4 radiodermatitis was observed. Conclusion: According to our noninferiority margin definition, the occurrence of skin toxicity and its related symptoms were statistically equivalent in both groups. No evidence was found to prohibit deodorant use (notwithstanding the use of an antiperspirant with aluminum) during RT for breast cancer.

    Staging by sentinel node (SN) biopsy is the standard procedure for clinically node-negative breast cancer patients. Intra-operative analysis of the SN allows immediate axillary lymph node (ALN) dissection in SN positive patients, but a quick, reliable and reproducible method is lacking. We tested the suitability of a quantitative cytokeratin 19 (CK19) mRNA one step nucleic acid amplification (OSNA#) technique (OSNA-CK19) for intra-operative SN analysis. OSNA-CK19 involves a short manual sample preparation step and subsequent fully automated amplification of CK19 mRNA based on reverse transcription loop-mediated isothermal amplification, with results available within 30–40 min. OSNA-CK19 was compared to histological staining (Hematoxylin&Eosin and CAM5.2 and CK19 immunostaining) of 346 frozen ALNs from 32 breast cancer patients, using half of the lymph node for each method. 267 samples were negative and 61 positive by both methods. Three samples were histology positive and OSNA-CK19 negative. Fifteen samples were histology negative and OSNA-CK19 positive, 11 of which had copy numbers close to the cut-off level of OSNA-CK19. Seven of these 15 samples were RT-PCR positive for epithelial markers and/or showed CK19 protein expression by Western blot suggesting the presence of tumor deposits in the lymph node part investigated by OSNA-CK19. Concordance with histology was 94.8%, and 96.8% after exclusion of the latter 7 discordant cases. Sensitivity was 95.3% and specificity was 94.7% before and 97.1% after discordant case investigation. Our results indicate that OSNA-CK19 can potentially be useful in an intra-operative clinical setting to detect SN tumor involvement in breast cancer patients. PMID:18324628

    Purpose: To examine the relationship between lymphovascular invasion (LVI) and regional nodal failure (RNF) in breast cancer patients with zero to three positive nodes treated with breast-conservation therapy (BCT). Methods and Materials: The records of 1,257 breast cancer patients with zero to three positive lymph nodes were reviewed. All patients were treated with BCT at Massachusetts General Hospital from 1980 to December 2003. Lymphovascular invasion was diagnosed by hematoxylin and eosin-stained sections and in some cases supported by immunohistochemical stains. Regional nodal failure was defined as recurrence in the ipsilateral supraclavicular, axillary, or internal mammary lymph nodes. Regional nodal failure was diagnosed by clinical and/or radiologic examination. Results: The median follow-up was 8 years (range, 0.1-21 years). Lymphovascular invasion was present in 211 patients (17%). In univariate analysis, patients with LVI had a higher rate of RNF (3.32% vs. 1.15%; p = 0.02). In multivariate analysis, only tumor size, grade, and local failure were significant predictors of RNF (p = 0.049, 0.013, and 0.0001, respectively), whereas LVI did not show a significant relationship with RNF (hazard ratio = 2.07; 95% CI, 0.8-5.5; p = 0.143). The presence of LVI in the T2/3 population did not increase the risk of RNF over that for those with no LVI (p = 0.15). In addition, patients with Grade 3 tumors and positive LVI did not have a higher risk of RNF than those without LVI (p = 0.96). Conclusion: These results suggest that LVI can not be used as a sole indicator for regional nodal irradiation in breast cancer patients with zero to three positive lymph nodes treated with BCT.

    AIM: To analyze predictive factors for lymph node metastasis in early gastric cancer. METHODS: We analyzed 1104 patients with early gastric cancer (EGC) who underwent a gastrectomy with lymph-node dissection from May 2003 through July 2011. The clinicopathologic factors and molecular markers were assessed as predictors for lymph node metastasis. Molecular markers such as microsatellite instability, human mutL homolog 1, p53, epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) were included. The ?2 test and logistic regression analysis were used to determine clinicopathologic parameters. RESULTS: Lymph node metastasis was observed in 104 (9.4%) of 1104 patients. Among 104 cases of lymph node positive patients, 24 patients (3.8%) were mucosal cancers and 80 patients (16.7%) were submucosal. According to histologic evaluation, the number of lymph node metastasis found was 4 (1.7%) for well differentiated tubular adenocarcinoma, 45 (11.3%) for moderately differentiated tubular adenocarcinoma, 36 (14.8%) for poorly differentiated tubular adenocarcinoma, and 19 (8.4%) for signet ring cell carcinoma. Of 690 EGC cases, 77 cases (11.2%) showed EGFR overexpression. HER2 overexpression was present in 110 cases (27.1%) of 406 EGC patients. With multivariate analysis, female gender (OR = 2.281, P = 0.009), presence of lymphovascular invasion (OR = 10.950, P < 0.0001), diameter (? 20 mm, OR = 3.173, P = 0.01), and EGFR overexpression (OR = 2.185, P = 0.044) were independent risk factors for lymph node involvement. CONCLUSION: Female gender, tumor size, lymphovascular invasion and EGFR overexpression were predictive risk factors for lymph node metastasis in EGC. PMID:25593477

    Introduction Locoregional relapse in medullary thyroid cancer (MTC) may be caused by nodal micrometastases. Medullary thyroid cancer lymph nodes have not yet been evaluated by one-step nucleic acid amplification (OSNA). Therefore, the aim of this study was to detect MTC cells by OSNA in cervical lymph nodes and compare the obtained outcomes with conventional histopathology. Material and methods Twenty-one randomized, unenlarged lymph nodes from 5 patients with MTC were examined by histopathology and OSNA. Lymph nodes were divided into four representative blocks by a sterile, single use, special cutting device in the same way as in the clinical protocol study performed by Tsujimoto et al. Two blocks were used for histopathology and immunohistochemistry, 2 for OSNA. Results Positive results of histopathology and OSNA were revealed in 4 patients. The outcomes of OSNA and histopathology were corresponding in 3 patients. Positive histopathology results of 2 lymph nodes from 2 patients were confirmed by OSNA. In 1 patient there were only negative results of both examinations. One-step nucleic acid amplification failed to detect metastasis in 1 lymph node in 2 patients although it did not change the TNM status in these patients. There were no false positive results in the OSNA test. Conclusions One-step nucleic acid amplification may be an alternative method to histopathology in detecting nodal involvement in MTC. Further studies should evaluate the sensitivity and specificity of OSNA and the impact on staging in MTC. PMID:25861300

    Objective: This study sought to evaluate the clinical outcome after extended sentinel lymph node dissection (eSLND) and radical retropubic prostatectomy (RRP) in patients with clinically localized prostate cancer (PCa). Subjects and Methods: From August 2002 until February 2011, a total of 819 patients with clinically localized PCa, confirmed by biopsy, were treated with RRP plus eSLND. Biochemical recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) were assessed with Kaplan-Meier curves. Various histopathological parameters were analyzed by univariate and multivariate analysis. Results: The mean follow-up was 5.3 years. Lymph node (LN) metastases occurred in 140 patients. We removed an average of 10.9 LNs via eSLND from patients with pN1 PCa. Postoperatively, 121 pN1 patients temporarily received adjuvant androgen deprivation therapy. The mean survival periods for RFS, RFS after secondary treatment, CSS, and OS were 4.7, 7.0, 8.8, and 8.1 years, respectively. The cancer-specific death rate of the 140 pN1 patients was 13.6%. RFS, CSS, and OS were significantly correlated with pathological margin status, LN density, the total diameter of evident metastases, and membership in the subgroup 'micrometastases only'. Conclusion: Despite the presence of LN metastases, patients with a low nodal tumor burden demonstrate a remarkable clinical outcome after undergoing eSLND and RRP, thus suggesting a potential curative therapeutic approach. © 2014 S.

    Colon cancer is the second most common type of cancer in females and the third in males, worldwide. The most common sites of colon cancer metastasis are the regional lymph nodes, liver, lung, bone and brain. In this study, an extremely rare case of colon adenocarcinoma with extensive metastasis to the mediastinal lymph nodes without any other organ involvement is presented. A 44-year-old Caucasian male presented with abdominal pain, a change in bowel habits, melena and weight loss. Colonoscopy revealed a large friable, ulcerated, circumferential mass in the ascending colon. Biopsies were consistent with the diagnosis of invasive moderately differentiated adenocarcinoma. Subsequently, right colon resection was performed, and pathological analysis revealed moderately differentiated adenocarcinoma of the right colon with extensive regional lymph node involvement. Computed tomography (CT) scans of the chest, abdomen and pelvis were performed preoperatively as part of routine staging for colon cancer. No liver or lung pathology was identified; however, multiple pathologically enlarged mediastinal lymph nodes were observed. Endoscopic ultrasound with fine needle aspiration of the largest mediastinal lymph node, which measured 5.2×3.5 cm on CT scans, was performed. The pathology was again consistent with the diagnosis of metastatic colorectal primary adenocarcinoma. At present, no optimum treatment has been identified for metastatic colon cancer to the mediastinal lymph nodes. The patient in the current case received chemotherapy with folinic acid, fluorouracil and oxaliplatin (FOLFOX), as well as with bevacizumab. Initial follow-up CT scans of the chest revealed a positive response to treatment. Physicians, in particular, radiologists, must consider the mediastinum during the first evaluation and further follow-up of patients with colorectal carcinoma even in the absence of metastasis.

    We report two cases of solitary mediastinal lymph node recurrence after colon cancer resection. Both cases had para-aortic lymph node metastasis at the time of initial surgery and received adjuvant chemotherapy for 4 years in case 1 and 18 mo in case 2. The time to recurrence was more than 8 years in both cases. After resection of the recurrent tumor, the patient is doing well with no recurrence for 6 years in case 1 and 4 mo in case 2. Patients should be followed up after colon cancer surgery considering the possibility of solitary mediastinal lymph node recurrence if they had para-aortic node metastasis at the time of initial surgery.

    Lymph node metastasis is one of the most important factors in therapy and prognosis for patients with parotid gland cancer. Nevertheless, the extent of the primary tumor resection and the necessity of a neck dissection still is a common issue. Since little is known about lymph node metastasis in early-stage parotid gland cancer, the purpose of the present study was to evaluate the occurrence of lymph node metastases in T1 and T2 carcinomas and its impact on local control and survival. We retrospectively analyzed 70 patients with early-stage (T1 and T2) primary parotid gland cancer. All patients were treated with parotidectomy and an ipsilateral neck dissection from 1987 to 2009. Clinicopathological and survival parameters were calculated. The median follow-up time was 51.7 months. A positive pathological lymph node stage (pN+) was found in 21.4% of patients with a significant correlation to the clinical lymph node stage (cN) (p = 0.061). There were no differences in the clinical and histopathological data between pN- and pN+ patients. In 73.3% of pN+ patients, the metastases were located intraparotideal. The incidence of occult metastases (pN+/cN-) was 17.2%. Of all patients with occult metastases, 30.0% had extraparotideal lymphatic spread. A positive lymph node stage significantly indicated a poorer 5-year overall as well as 5-year disease-free survival rate compared to pN- patients (p = 0.048; p = 0.011). We propose total parotidectomy in combination with at least a level II-III selective neck dissection in any case of early-stage parotid gland cancer. PMID:21671057

    Background To date, pathological examination of specimens remains largely qualitative. Quantitative measures of tissue spatial features are generally not captured. To gain additional mechanistic and prognostic insights, a need for quantitative architectural analysis arises in studying immune cell-cancer interactions within the tumor microenvironment and tumor-draining lymph nodes (TDLNs). Methodology/Principal Findings We present a novel, quantitative image analysis approach incorporating 1) multi-color tissue staining, 2) high-resolution, automated whole-section imaging, 3) custom image analysis software that identifies cell types and locations, and 4) spatial statistical analysis. As a proof of concept, we applied this approach to study the architectural patterns of T and B cells within tumor-draining lymph nodes from breast cancer patients versus healthy lymph nodes. We found that the spatial grouping patterns of T and B cells differed between healthy and breast cancer lymph nodes, and this could be attributed to the lack of B cell localization in the extrafollicular region of the TDLNs. Conclusions/Significance Our integrative approach has made quantitative analysis of complex visual data possible. Our results highlight spatial alterations of immune cells within lymph nodes from breast cancer patients as an independent variable from numerical changes. This opens up new areas of investigations in research and medicine. Future application of this approach will lead to a better understanding of immune changes in the tumor microenvironment and TDLNs, and how they affect clinical outcomes. PMID:20811638

    SYNOPSIS Significant progress has been made in the surgical management of breast cancer. Historically, women with invasive breast cancer underwent a Halsted radical mastectomy; morbid procedure removing the breast, underlying muscle and regional lymph nodes. In contemporary practice, the majority of women diagnosed with early stage invasive breast cancer can now be managed with breast conserving therapy to include a segmental mastectomy followed by radiation. Axillary lymph nodes are routinely assessed by sentinel lymph node biopsy. Axillary lymph node dissection is reserved for patients with documented nodal metastasis, however, here too progress has been made as a population of low risk patients has been identified in whom a complete dissection is not required even in the setting of a positive sentinel lymph node. This chapter details the landmark clinical trials that have guided the surgical management of breast cancer. PMID:23464699

    How tumors access and spread via the lymphatics is not understood. Although it is clear that dissemination via the blood system involves hemangiogenesis, it is uncertain whether tumors also induce lymphangio- genesis or simply invade existing peritumoral vessels.

    Gastric cancer remains the second leading cause of cancer deaths worldwide. Patients usually present late with local invasion or metastatic diseases. The present study investigated the expression level of liver-intestine cadherin (LI-cadherin) by RT-PCR and its correlation with clinicopathological data in 71 pairs of tumor and non-cancerous gastric mucosa. Protein expression level of LI-cadherin was determined by Western blotting and immunohistochemistry. The mRNA of LI-cadherin was highly expressed in tumor as compared to non-cancerous mucosa. Lymph node metastasis was significantly associated with the expression of LI-cadherin (p=0.038). On multivariate analysis, T staging and LI-cadherin expression were found to be independent factors associated with lymph node metastasis. PMID:15178443

    Purpose. The purpose of this study was to analyze the expression of zinc-finger E-box-binding homeobox 1 (ZEB1) in endometrial biopsy and its correlation with preoperative characteristics, including lymph node metastases in patient with endometrial cancer. Methods. Using quantitative RT-PCR, ZEB1 expressions in endometrial biopsy from 452 patients were measured. The relationship between ZEB1 expression and preoperative characteristics was analyzed. Results. ZEB1 expressions were significantly associated with subtype, grade, myometrial invasion, and lymph node metastases. Lymph node metastases could be identified with a sensitivity of 57.8% at specificity of 74.1% by ZEB1 expression in endometrial biopsy. Based on combination of preoperative characteristics and ZEB1 expression, lymph node metastases could be identified with a sensitivity of 62.1% at specificity of 96.2% prior to hysterectomy. Conclusion. ZEB1 expression in endometrial biopsy could help physicians to better predict the lymph node metastasis in patients with endometrial cancer prior to hysterectomy. PMID:25544793

    BACKGROUND A wide range of false-negative rates has been reported for sentinel lymph node (SLN) biopsy after preoperative chemotherapy. The purpose of this study was to determine whether histologic findings in negative SLNs after preoperative chemotherapy are helpful in assessing the accuracy of SLN biopsy in patients with confirmed lymph node-positive disease before treatment. METHODS Eighty-six patients with confirmed lymph node-positive disease at presentation underwent successful SLN biopsy and axillary dissection after preoperative chemotherapy at a single institution between 1994 and 2007. Available hematoxylin and eosin-stained sections from patients with negative SLNs were reviewed, and associations between histologic findings in the negative SLNs and SLN status (true negative vs false negative) were evaluated. RESULTS Forty-seven (55%) patients had at least 1 positive SLN, and 39 (45%) patients had negative SLNs. The false-negative rate was 22%, and the negative predictive value was 67%. The negative SLNs from 17 of 34 patients with available slides had focal areas of fibrosis, some with associated foamy parenchymal histiocytes, fat necrosis, or calcification. These histologic findings occurred in 15 (65%) of 23 patients with true-negative SLNs and in only 2 (18%) of 11 patients with false-negative SLNs (P =.03, Fisher exact test, 2-tailed). The lack of these histologic changes had a sensitivity and specificity for identifying a false-negative SLN of 82% and 65%, respectively. CONCLUSIONS Absence of treatment effect in SLNs after chemotherapy in patients with lymph node-positive disease at initial presentation has good sensitivity but low specificity for identifying a false-negative SLN.

    Breast cancer is most often treatable when detected in the early stages, before the primary disease spreads to sentinel lymph nodes in the axilla and supraclavicular region. A sentinel lymph node is the closest adjacent lymph node to receive lymphatic drainage from a primary breast tumour. It is from these nodes that cancer cells metastasise throughout the lymphatic system, spreading the disease. This work details the optical Monte Carlo modelling of an ultra compact, nuclear medicine ? camera that will be used intra-operatively to detect malignant sentinel lymph nodes. This development will improve the identification and localisation of these sentinel nodes, thereby facilitating improved techniques for axillary lymph node dissection, and sentinel lymph node biopsy.

    The standard technique using lymphoscintigraphy, blue dye and a gamma probe has established a reliable method for sentinel node biopsy for skin cancer. However, the detection rate of cervical sentinel lymph nodes (SLN) is generally lower than that of inguinal or axillary SLN because of the complexity of lymphatic drainage in the head and neck region and the "shine-through" phenomenon. Recently, indocyanine green fluorescence imaging has been reported as a new method to detect SLN. We hypothesized that fluorescence navigation with indocyanine green in combination with the standard technique would improve the detection rate of cervical sentinel nodes. We performed cervical sentinel node biopsies using the standard technique in 20 basins of 18 patients (group A) and using fluorescence navigation in combination with the standard technique in 12 basins of 16 patients (group B). The mean number of sentinel nodes was two per basin (range, 1-4) in group A and three per basin (range, 1-5) in group B. The detection rate of sentinel nodes was 83% (29/35) in group A and 95% (36/38) in group B. The false-negative rate was 6% (1/18 patients) in group A and 0% in group B. Fluorescence navigation with indocyanine green may improve the cervical sentinel node detection rate. However, greater collection of data regarding the usefulness of cervical sentinel node biopsy using indocyanine green is necessary. PMID:23621899

    ABSTRACT Understanding the cytokine/chemokine networks in CD4+ and CD8+ T cells during the acute phase of infection is crucial to design therapies for the control of early human immunodeficiency virus (HIV)/simian immunodeficiency virus (SIV) replication. Here, we measured early changes in CD4+ and CD8+ T cells in the peripheral blood (PB), bone marrow (BM), and axillary lymph node (ALN) tissue of rhesus macaques infected with SIVMAC251. At 21 days after infection, all tissues showed a statistically significant loss of CD4+ T cells along with immune activation of CD8+ T cells in PB and ALN tissue. Twenty-eight different cytokines/chemokines were quantified in either anti-CD3/28 antibody- or staphylococcal enterotoxin B-stimulated single-positive CD4+ and CD8+ T cells. PB CD4+ T cells produced predominantly interleukin-2 (IL-2), whereas CD4+ and CD8+ T-cell subsets in tissues produced ?-chemokines both before and 21 days after SIV infection. Tissues generally exhibited massive upregulation of many cytokines/chemokines following infection, possibly in an attempt to mitigate the loss of CD4+ T cells. There was no evidence of a T-helper 1 (TH1)-to-TH2 shift in CD4+ T cells or a T-cytotoxic 1 (TC1)-to-TC2 cytokine shift in CD8+ T cells in PB, BM, and ALN T-cell subsets during the acute phase of SIV infection. Despite the upregulation of several important effector cytokines/chemokines (IL-2, IL-12, IL-17, gamma interferon, granulocyte-macrophage colony-stimulating factor) by CD4+ and CD8+ T cells, upregulation of ?-chemokines (CCL2 and CCL22), basic fibroblast growth factor (FGF-basic), hepatocyte growth factor (HGF), and migration inhibition factor (MIF) may provide a poor prognosis either by inducing increased virus replication or by other unknown mechanisms. Therefore, drugs targeting ?-chemokines (CCL2 and CCL22), FGF-basic, HGF, or MIF might be important for developing effective vaccines and therapeutics against HIV. IMPORTANCE Human immunodeficiency virus (HIV)/simian immunodeficiency virus (SIV) infection results in early depletion of CD4+ T cells and dysregulation of protective immune responses. Therefore, understanding the cytokine/chemokine networks in CD4+ and CD8+ T cells in different tissues during the acute phase of infection is crucial to the design of therapies for the control of early viral replication. Here, we measured early changes in CD4+ and CD8+ T cells in peripheral blood (PB), bone marrow (BM), and axillary lymph node (ALN) tissue of rhesus macaques infected with SIVMAC251. There was no evidence of a T-helper 1 (TH1)-to-TH2 shift in CD4+ T cells or a T-cytotoxic 1 (TC1)-to-TC2 cytokine shift in CD8+ T cells in PB, BM, and ALN T-cell subsets during the acute phase of SIV infection. Despite the upregulation of several important effector cytokines/chemokines by CD4+ and CD8+ T cells, upregulation of ?-chemokines, fibroblast growth factor-basic, hepatocyte growth factor, and migration inhibition factor may provide a poor prognosis.

    Accurate lymph nodal staging of lung cancer is critical for determining the treatment options. With the help of 18F-fluorodeoxyglucose positron emission tomography/computer tomography (18F-FDG-PET/CT), the clinician can rule out/in the regional lymph nodes positive for metastasis in the patients with lung cancer in a majority of cases. However, a small proportion of cases with false positivity of metastasis have been reported. Transbronchial needle aspirations and mediastinoscopic biopsies are still necessary to determine whether enlarged hypermetabolic mediastinal lymph nodes are positive for lung cancer metastasis. Here we report three intricate cases showing hypermetabolic activity in the mediastinal lymph nodes in the patients with pathologically diagnosed lung cancer on PET/CT. The first patient had squamous cell carcinoma in the left upper lobe of the lung with surrounding necrotizing granulomas and concurrent with silicosis and granulomatous inflammation in the lymph nodes; the second presented with symptoms of viral pneumonia, which was pathologically diagnosed as a lung adenocarcinoma, stage IA, concurrent with sarcoidosis involving the lymph nodes; the last case was diagnosed as squamous cell carcinoma in the right upper lobe of the lung, but lymph nodes showed reactive hyperplasia. These cases suggest that some cases are so complex that avid 18F-FDG uptake in the mediastinal lymph nodes in the patients with pathologically diagnosed lung cancer should be carefully analyzed based on individual patients’ clinical background.

    During the last decade, several analyses of prognostic factors for differentiated thyroid cancer (DTC) have been reported. Although these studies have established a framework for rational treatment planning, they have not fully answered questions regarding the prognostic significance of cervical lymph node metastases. An analysis of patients treated for DTC at our institution over a 34-year period has shown several factors to be significant by log-rank analysis, including the presence of cervical lymph node metastases, age greater than or equal to 50 years, a primary cancer size of greater than 3.0 cm, and distant metastases. Further analysis has shown the node-negative and node-positive patient groups to be similar in regard to age, size of primary cancer, and the presence of distant metastases. This report compares our data with those of other studies that have investigated the association of cervical lymph node metastases and a poorer prognosis in patients with DTC. When considered as a group, these studies support the finding of the prognostic significance of cervical lymph node metastases, particularly that of palpable lymphadenopathy in older patients.

    Abstract Background: Approximately 72% of endometrial cancers are FIGO stage I at diagnosis and about 10% have lymph node metastases. An ideal diagnostic test for nodal disease would be able to prevent both overtreatment (i.e. unnecessary lymphadenectomy) and undertreatment (i.e. withholding lymphadenectomy or adjuvant postoperative treatment to patients with lymph node metastases). Objectives: In this review we compare the accuracy of preoperative tests (computed tomography, magnetic resonance imaging, positron emission tomography-computed tomography, CA-125 serum levels, and ultrasonography) for the detection of lymph node metastases in endometrial cancers with the final histopathologic diagnosis after complete pelvic and para-aortic lymphadenectomy as the gold standard. Method: A systematic search in MEDLINE (using PubMed), Embase and The Cochrane Library was performed up to 23 July 2012. Results: We found one article that met our inclusion criteria for computed tomography, none for magnetic resonance imaging, 2 for positron emission tomography/computed tomography), 2 for CA-125 and none for ultrasonography. Conclusions: Due to the lack of high-quality articles on a preoperative test for lymph node status in endometrial cancer, no proper comparison between these modalities can be made. PMID:23876490

    The 7th TNM classification clearly states that micrometastases detected by morphological techniques (HE stain and immunohistochemistry) should always be reported and calculated in the staging of the disease (pN1mi or M1), while patients in whom micrometastases are detected by non-morphological techniques (e.g., flow cytometry, reverse-transcriptase polymerase chain reaction) should still be classified as N0 or M0. In gastric cancer patients, micrometastases have been detected in lymph nodes, the peritoneal cavity and bone marrow. However, the clinical implications and/or their prognostic significance are still a matter of debate. Current literature suggests that lymph node micrometastases should be encountered for the loco-regional staging of the disease, while skip lymph node micrometastases should also be encountered in the total number of infiltrated lymph nodes. Peritoneal fluid cytology examination should be obligatorily performed in pT3 or pT4 tumors. A positive cytology classifies gastric cancer patients as stage IV. Although a curative resection is not precluded, these patients face an overall dismal prognosis. Whether patients with a positive cytology should be treated similarly to patients with macroscopic peritoneal recurrence should be evaluated further. Gastric cancer cells are detected with high incidence in the bone marrow. However, the published results make comparison of data between groups almost impossible due to severe methodological problems. If these methodological problems are overcome in the future, specific target therapies may be designed for specific groups of patients. PMID:22403737

    Background The number of lymph nodes examined during colon cancer surgery falls below nationally recommended guidelines in the general population, with blacks and Hispanics less likely to have adequate nodal evaluation in comparison to whites. The Department of Defense’s (DoD’s) Military Health System (MHS) provides equal access to medical care for its beneficiaries, regardless of racial/ethnic background. This study aimed to investigate whether racial/ethnic treatment differences exist in the MHS, an equal access medical care system. Methods Linked data from the DoD cancer registry and administrative claims databases were used and included 2,155 colon cancer cases. Multivariate logistic regression assessed the association between race/ethnicity and the number of lymph nodes examined (<12 and ? 12) overall and for stratified analyses. Results No overall racial/ethnic difference in the number of lymph nodes examined was identified. Further stratified analyses yielded similar results, except potential racial/ethnic differences were found among persons with poorly differentiated tumors, where non-Hispanic blacks (NHBs) tended to be less likely to have ?12 lymph nodes dissected (OR: 0.34, 95% CI: 0.14-0.80, p-value: 0.01) compared to non-Hispanic whites. Conclusion Racial/ethnic disparities in the number of lymph nodes evaluated among patients with colon cancer were not apparent in an equal-access healthcare system. However, among poorly differentiated tumors, there might be racial/ethnic differences in nodal yield, suggesting the possible effects of factors other than access to healthcare. PMID:25059789

    The membrane glycoprotein podoplanin is expressed by several types of human cancers and might be associated with their malignant progression. Its exact biological function and molecular targets are unclear, however. Here, we assessed the relevance of tumor cell expression of podoplanin in cancer metastasis to lymph nodes, using a human MCF7 breast carcinoma xenograft model. We found that podoplanin expression promoted tumor cell motility in vitro and, unexpectedly, increased tumor lymphangiogenesis and metastasis to regional lymph nodes in vivo, without promoting primary tumor growth. Importantly, high cancer cell expression levels of podoplanin correlated with lymph node metastasis and reduced survival times in a large cohort of 252 oral squamous cell carcinoma patients. Based on comparative transcriptional profiling of tumor xenografts, we identified endothelin-1, villin-1, and tenascin-C as potential mediators of podoplanin-induced tumor lymphangiogenesis and metastasis. These unexpected findings identify a novel mechanism of tumor lymphangiogenesis and metastasis induced by cancer cell expression of podoplanin, suggesting that reagents designed to interfere with podoplanin function might be developed as therapeutics for patients with advanced cancer.

    Collagen I (Col1) fibers are a major structural component in the extracellular matrix of human breast cancers. In a preliminary pilot study, we explored the link between Col1 fiber density in primary human breast cancers and the occurrence of lymph node metastasis. Col1 fibers were detected by second harmonic generation (SHG) microscopy in primary human breast cancers from patients presenting with lymph node metastasis (LN+) versus those without lymph node metastasis (LN-). Col1 fiber density, which was quantified using our in-house SHG image analysis software, was significantly higher in the primary human breast cancers of LN+ (fiber volume=29.22%±4.72%, inter-fiber distance=2.25±0.45 ?m) versus LN- (fiber volume=20.33%±5.56%, inter-fiber distance=2.88±1.07 ?m) patients. Texture analysis by evaluating the co-occurrence matrix and the Fourier transform of the Col1 fibers proved to be significantly different for the parameters of co-relation and energy, as well as aspect ratio and eccentricity, for LN+ versus LN- cases. We also demonstrated that tissue fixation and paraffin embedding had negligible effect on SHG Col1 fiber detection and quantification. High Col1 fiber density in primary breast tumors is associated with breast cancer metastasis and may serve as an imaging biomarker of metastasis.

    Background Our goal is to validate the Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram and Stanford Online Calculator (SOC) for predicting non-sentinel lymph node (NSLN) metastasis in Chinese patients, and develop a new model for better prediction of NSLN metastasis. Methods The MSKCC nomogram and SOC were used to calculate the probability of NSLN metastasis in 120 breast cancer patients. Univariate and multivariate analyses were performed to evaluate the relationship between NSLN metastasis and clinicopathologic factors, using the medical records of the first 80 breast cancer patients. A new model predicting NSLN metastasis was developed from the 80 patients. Results The MSKCC and SOC predicted NSLN metastasis in a series of 120 patients with an area under the receiver operating characteristic curve (AUC) of 0.688 and 0.734, respectively. For predicted probability cut-off points of 10%, the false-negative (FN) rates of MSKCC and SOC were both 4.4%, and the negative predictive value (NPV) 75.0% and 90.0%, respectively. Tumor size, Kiss-1 expression in positive SLN and size of SLN metastasis were independently associated with NSLN metastasis (p<0.05). A new model (Peking University People's Hospital, PKUPH) was developed using these three variables. The MSKCC, SOC and PKUPH predicted NSLN metastasis in the second 40 patients from the 120 patients with an AUC of 0.624, 0.679 and 0.795, respectively. Conclusion MSKCC nomogram and SOC did not perform as well as their original researches in Chinese patients. As a new predictor, Kiss-1 expression in positive SLN correlated independently with NSLN metastasis strongly. PKUPH model achieved higher accuracy than MSKCC and SOC in predicting NSLN metastasis in Chinese patients. PMID:25111296

    In the recent years several studies have shown that about 30% of cases with axillary node-nagative breast cancer suffer relapse of the disease. Our attempt was made to evaluate the most significant prognostic factors to predict this high risk group which may be benefited from adjuvant treatment. For this purpose, we selected 9 patients out of 80 cases of node-negative breast cancer who had been followed up at least for 5 years and had the recurrence of the disease. For comparison, 16 patients from the same group who did not have relapse were selected on a random basis. Histology, receptor status, AgNOR, DNA flow cytometry and various immunohistochemical parameters were compared between the groups with recurrence and that without recurrence. On univariate analysis, tumor size, immunohistochemical expressions of PCNA, MIB-1, c-erbB-2 and S-phase fraction were significantly different between the above two groups. By multivariate analysis, immunohistochemical c-erbB-2 expression (more than 50% of cancer cells) was an independent parameter. As a summary from our studies, c-erbB-2 immunohistochemical staining on paraffin sections might be the best independent prognostic factor in axillary node-negative breast cancers. PMID:11091532

    Somatic mutations reported in large-scale breast cancer (BC) sequencing studies primarily consist of protein coding mutations. mRNA splicing mutation analyses have been limited in scope, despite their prevalence in Mendelian genetic disorders. We predicted splicing mutations in 442 BC tumour and matched normal exomes from The Cancer Genome Atlas Consortium (TCGA). These splicing defects were validated by abnormal expression changes in these tumours. Of the 5,206 putative mutations identified, exon skipping, leaky or cryptic splicing was confirmed for 988 variants. Pathway enrichment analysis of the mutated genes revealed mutations in 9 NCAM1-related pathways, which were significantly increased in samples with evidence of lymph node metastasis, but not in lymph node-negative tumours. We suggest that comprehensive reporting of DNA sequencing data should include non-trivial splicing analyses to avoid missing clinically-significant deleterious splicing mutations, which may reveal novel mutated pathways present in genetic disorders.

    Purpose: To analyze the cranial distribution of level II lymph nodes in patients with laryngeal cancer to optimize the elective radiation nodal target volume delineation. Methods and Materials: The most cranially located metastatic lymph node was delineated in 67 diagnostic CT data sets. The minimum distance from the base of the skull (BOS) to the lymph node was determined. Results: A total of 98 lymph nodes were delineated including 62 ipsilateral and 36 contralateral lymph nodes. The mean ipsilateral and contralateral distance from the top of the most cranial metastatic lymph node to the BOS was 36 mm (range, -9-120; standard deviation [SD], 17.9) and 35 mm (range, 14-78; SD 15.0), respectively. Only 5% and 12% of the ipsilateral and 3% and 9% of the contralateral metastatic lymph nodes were located within 15 mm and 20 mm below the BOS, respectively. No significant differences were found between patients with only ipsilateral metastatic lymph nodes and patients with bilateral metastatic lymph nodes. Between tumors that do cross the midline and those that do not, no significant difference was found in the distance of the most cranial lymph node to the BOS and the occurrence ipsilateral or contralateral. Conclusions: Setting the cranial border of the nodal target volume 1.5 cm below the base of the skull covers 95% of the lymph nodes and should be considered in elective nodal irradiation for laryngeal cancer. Bilateral neck irradiation is mandatory, including patients with unilateral laryngeal cancer, when elective irradiation is advised.

    AIM: To screen lymph nodes metastasis associated long noncoding RNAs (lncRNAs) in colorectal cancer through microarray analysis. METHODS: Metastatic lymph node (MLN), normal lymph node (NLN) and tumor tissues of 3 colorectal cancer (CRC) patients were collected during the operation and validated by pathological examinations. RNAs were extracted from MLN, NLN, and cancer tissues separately. RNA quantity and quality were measured with a NanoDrop ND-1000 spectrophotometer and RNA integrity was assessed by standard denaturing agarose electrophoresis. Agilent Feature Extraction Software (Version 11.0.1.1) was used to analyze acquired array images. Four differently expressed lncRNAs were confirmed by quantitative real-time polymerase chain reaction (qRT-PCR) in 26 subsets of MLN, NLN, and tumor tissues. RESULTS: Of 33045 lncRNAs, 1133 were differentially expressed in MLN compared with NLN, of which 260 were up-regulated and 873 down-regulated (? 2 fold-change). Five hundred and forty-five lncRNAs were differentially expressed in MLN compared with tumor tissues, of which 460 were up-regulated and 85 down-regulated (? 2 fold-change). Compared with NLN and cancer tissues, 14 lncRNAs were specifically up-regulated and 5 specifically down-regulated in MLN. AK307796, ENST00000425785, and AK021444 were confirmed to be specifically up-regulated in MLN and ENST00000465846 specifically down-regulated in MLN by qRT-PCR in 26 CRC patients. CONCLUSION: The specifically expressed lncRNAs in MLN may exert a partial or key role in the progress of lymph nodes metastasis of CRC. PMID:25009386

    Glutathione peroxidase 3 (GPX3) is a member of the glutathione peroxidase family of selenoproteins and is one of the key defensive enzymes against oxidative damages to host cells. Downregulation of GPX3 due to its promoter hypermethylation has been documented in several different types of cancer, indicating that GPX3 functions as a possible tumor suppressor. In the present study, we showed that GPX3 is also significantly downregulated in cervical cancer tissues compared to normal cervical tissues by qRT-PCR analyses and immunohistostainings. GPX3 expression was significantly related to lymph node metastasis and prognosis in cervical cancer patients. Treatment of cervical cancer cells with 5-aza-2'-deoxycytidine restored the expression of GPX3 and methylation-specific PCR (MSP) confirmed the CpG methylation of the GPX3 gene. Our results indicate that promoter methylation is one of the major causes of GPX3 downregulation in cervical cancer and GPX3 could serve as a predictive biomarker for lymph node metastasis and prognosis of cervical cancer.

    Silicone-gel-filled breast implants have been widely used for breast augmentation and reconstruction after mastectomy. However, silicone implants have some well-known complications, such as implant rupture, which requires surgical intervention. Dissemination of silicone particles out of the implant causes a granulomatous reaction, a phenomenon known as silicone granuloma, in breast parenchyma as well as axillary, breast and chest wall lymph nodes, which mimics breast cancer metastasis. However, lipogranuloma after silicone breast implant rupture has not been reported in the literature, although it is a common complication after mineral oil or liquid silicone injection. We present a case report of an axillary lymphadenopathy resulting from lipogranuloma after silicone-gel-filled implant rupture. Review of the literature suggests that this is the first report of a lipogranuloma resulting from implant rupture. PMID:23245917

    BACKGROUND A new diagnostic system, called one-step nucleic acid amplification (OSNA), has recently been designed to detect cytokeratin 19 mRNA as a surrogate for lymph node metastases. The objective of this prospective investigation was to compare the performance of OSNA with both standard hematoxylin and eosin (H&E) analysis and intensive histopathology in the detection of colon cancer lymph node metastases. METHODS In total, 313 lymph nodes from 22 consecutive patients with stage I, II, and III colon cancer were assessed. Half of each lymph node was analyzed initially by H&E followed by an intensive histologic workup (5 levels of H&E and immunohistochemistry analyses, the gold standard for the assessment of sensitivity/specificity of OSNA), and the other half was analyzed using OSNA. RESULTS OSNA was more sensitive in detecting small lymph node tumor infiltrates compared with H&E (11 results were OSNA positive/H&E negative). Compared with intensive histopathology, OSNA had 94.5% sensitivity, 97.6% specificity, and a concordance rate of 97.1%. OSNA resulted in an upstaging of 2 of 13 patients (15.3%) with lymph node-negative colon cancer after standard H&E examination. CONCLUSIONS OSNA appeared to be a powerful and promising molecular tool for the detection of lymph node metastases in patients with colon cancer. OSNA had similar performance in the detection of lymph node metastases compared with intensive histopathologic investigations and appeared to be superior to standard histology with H&E. Most important, the authors concluded that OSNA may lead to a potential upstaging of >15% of patients with colon cancer. Cancer 2012. © 2012 American Cancer Society. PMID:22684906

    STAT3 is constitutively activated in many human cancers including gastric cancer and plays crucial roles in modulating cancer cell proliferation, survival, metastasis as well as the microenvironment of pre-metastatic niches. Accumulating evidence has implicated STAT3 as a promising target for cancer therapy and it has been well established that tumor cell metastasized to lymph node is associated with poor prognosis. However, little is known about the relation between STAT3 activation in tumor cell-free lymph nodes and patient clinical outcomes. The objective of the current study was to investigate the role of STAT3 activity in tumor cell-free lymph nodes in tumor progression and prognosis for gastric cancer patients. Immunohistochemical analyses for p-STAT3, Ki-67, CD68 and Bcl-xL were performed in tumor cell-free lymph nodes from 60 gastric cancer patients. Survival analysis was conducted by using the Kaplan-Meier method. Immunohistochemical analyses showed that hyperactivity of STAT3 in tumor cell-free lymph nodes was significantly associated with tumor recurrence, and STAT3 activation pattern coincides with expression Ki-67, CD68, Bcl-xL. Survival analysis revealed that persistent STAT3 activation in uninvolved lymph nodes was positively associated with poor overall survival (P<0.05). These findings suggest that STAT3 activation in tumor-free lymph nodes is involved in the pathogenesis and metastasis of gastric cancer and that elevated STAT3 activity in lymph nodes prior to tumor cell arrival may indicate a poorer prognosis. These clinical studies support our findings in mouse tumor models showing that STAT3 activation is crucial for pre-metastatic niche formation and metastasis. PMID:24696730

    Objective. The role of single preoperative serum CA-125 levels in predicting pelvic or paraaortic lymph node metastasis in patients operated for epithelial ovarian cancer has been investigated. Methods. 176 patients diagnosed with epithelial ovarian carcinoma after staging laparotomy between January 2002 and May 2010 were evaluated retrospectively. Results. The mean, geometric mean, and median of preoperative serum CA-125 levels were 632,6, 200,29, and 191,5?U/mL, respectively. The cut-off value predicting lymph node metastases in the ROC curve was 71,92?U/mL, which is significant in logistic regression analysis (P = 0.005). The preoperative log CA-125 levels were also statistically significant in predicting lymph node metastasis in logistic regression analysis (P = 0.008). Conclusions. The tumor marker CA-125, which increases with grade independent of the effect of stage in EOC, is predictive of lymph node metastasis with a high rate of false positivity in Turkish population. The high false positive rate may obscure the predictive value of CA-125. PMID:24795494

    Purpose Differentiated thyroid cancer has a good prognosis and high incidence in young women. Since endoscopic techniques were first recorded in 1996, surgical indications of endoscopic thyroidectomy have broadened. Therefore, the aim of this study is to investigate the usefulness of endoscopic thyroidectomy in clinically lymph node negative (cN0) thyroid cancer patients, based on oncologic completeness and safety, considering cosmetic outcomes. Methods From July 2009 to June 2011, a total of 166 cases had undergone endoscopic thyroidectomy using the BABA (bilateral axillo-breast approach) method or conventional open thyroidectomy by one surgeon. Finally, excluding 72 patients, 94 patients with cN0 thyroid cancer were divided into two groups according to operative methods and analyzed to compare differences between the two methods retrospectively (endoscopic group, n = 49; conventional open group, n = 45). Results We practiced comparative analysis for clinicopathologic characteristics, surgical outcomes including postoperative complications, and recurred cases during follow-up periods of each group. The results showed there was a tendency for patients, young, women rather than men, and having small size of thyroid cancer, to prefer endoscopic surgery to open surgery. Meanwhile, in postoperative complications, there were no statistically significant differences. During short follow-up periods, no recurrence or mortality case was observed. Conclusion Endoscopic thyroidectomy is a feasible and safe method for the treatment of clinically lymph node negative (cN0) thyroid cancer. PMID:25692117

    Sentinel lymph node biopsy (SLNB) has been widely performed and become the standard procedure for axillary staging in breast cancer patients. In current SLNB, identification of SLNs is prerequisite, and blue dye and/or radioactive colloids are clinically used for mapping. However, these methods are still intraoperative, and especially radioactive colloids based method is ionizing. As a result, SLNB is generally associated with ill side effects. In this study, we have proposed near-infrared Au nanocages as a new tracer for noninvasive and nonionizing photoacoustic (PA) SLN mapping in a rat model as a step toward clinical applications. Au nanocages have great features: biocompatibility, easy surface modification for biomarker, a tunable surface plasmon resonance (SPR) which allows for peak absorption to be optimized for the laser being used, and capsule-type drug delivery. Au nanocage-enhanced photoacoustic imaging has the potential to be adjunctive to current invasive SLNB for preoperative axillary staging in breast cancer patients.

    The long-term mortality risk from prostate cancer increases in lymph node (LN) positive patients. This study was done to assess the effect of lymph node Gleason score (LNGS) on prognosis in patients with LN-positive prostate cancer. Among the 1,415 patients who received pelvic lymph node dissection (PLND), 117 (8.4%) patients had a positive LN. The PGS of the prostate specimens and the LNGS of the positive LNs were assessed by uropathologists. The median age of patients at surgery was 67 years (interquartile range [IQR], 62-71 years) and the median follow-up duration was 44.3 months (IQR, 27.0-78.5 months). Pathologic Gleason scores (PGS) of 6-9 included one (0.9%), 53 (49.5%), 22 (20.6%), and 31 (29.0%) patients. The median total number of retrieved LNs was 9.0 (IQR, 5.3-12.8). The median number of positive LNs was one (IQR, 1-2). Cancer architecture with a Gleason pattern and score were observed in LNs as in ordinary prostate specimens. LNGS 6-9 included nine (8.1%), 57 (51.4%), 31 (27.9%), and 14 (12.6%) patients. The speaman’s analysis showed the meaningful correlation between PGS and LNGS (P = 0.249, P = 0.011). The univariate analysis showed that the number of positive LNs and LNGS were significantly associated with prostate cancer-specific survival (P = 0.028; P = 0.005). The same architecture that is seen in the prostate was seen in positive LNs, and LNGS may be a significant prognostic factor in patients with LN-positive prostate cancer. PMID:25337262

    Objective To explore the accuracy of sentinel lymph node (SLN) dissection in predicting regional lymph node status by using either only Technetium-99m-labelled (Tc-99m) or in combination with a blue dye in patients with squamous cell cancer of vulva. Material and Methods Twenty-one patients who had T1 (?2 cm) or T2 (>2cm) tumors that did not encroach into the urethra, vagina or anus were included in the study. For the first twelve patients, Tc-99m was used for SLN identification, and the combined technique was used in subsequent patients. Preoperatively, Tc-99m and a blue dye was injected intradermally around the tumor. Following SLN dissection, complete inguinofemoral lymphadenectomy was performed. Results We could detect SLN in all 21 patients (100%) by either Tc-99m or the combined method. SLN was found to be histopathologically negative in 13 groins via Tc-99m and 10 groins via the combined method. Twenty-one of these 23 (91.3%) groin non-SLN were also negative, but in two groins, we detected metastatic non-SLN. Conclusion Although SLN dissection appears promising in vulvar cancer, false negative cases are reported in the literature. Sentinel lymph node dissection without complete lymphadenectomy does not seem appropriate for routine clinical use, since it is known that groin metastasis is fatal. PMID:24592094

    We have performed intraoperative fluorescence diagnostics of 60 patients for metastases of breast cancer to regional lymph nodes. All the patients were divided into two groups. The first group consisted of 50 patients, which were surgically treated at the first stage. The second group consisted of ten patients, which underwent combined treatment. At the first stage, they received from two to four courses of neoadjuvant chemotherapy, and, at the second stage, the surgical intervention was performed. The intraoperative fluorescence diagnostics was performed using the preparation alasens (precursor of protoporphyrin IX in the human organism). The occurrence of fluorescence of alasens-induced protoporphyrin IX was determined visually and using the local fluorescence spectroscopy method. Altogether, 498 lymph nodes were examined: 408 in the first group and 90 in the second one. For the first group, the sensitivity of the method was found to be 87.2%, and its specificity, 94.8%; in the second group, these parameters were determined to be 77 and 78%, respectively. The first experience of the application of the intraoperative fluorescence diagnostics of metastatic lesion of lymph nodes in patients with breast cancer has shown its high efficiency and application potential.

    The number of breast augmentation surgeries (BAS) has increased. Therefore, the number of breast cancer patients with history of BAS has also increased. In this paper, we present two cases of sentinel lymph node biopsy (SLNB) in patients with previous BAS who were diagnosed with breast cancer. The patients were augmented using different approach; the first case was augmented through transaxillary incision, whereas the second case was augmented through periareolar incision. Lymphoscintigraphy (LPG) was performed on the patients 1 day prior to operation, enabling confirmation of lymphatic flow and SLN in both patients. SLNB was successfully performed in both cases. In one patient, SLNB was performed using indocyanine green (ICG) fluorescence and the Photodynamic Eye (PDE) system. Regardless of history of BAS, ICG and PDE system showed lymphatic flow and SLN in real time. LPG and ICG fluorescence were useful methods for SLN detection in patients with previous BAS, being able to confirm lymph flow before operation. Biopsy methods using LPG and PDE system were considered useful for difficult confirmation of lymph flow after breast augmentation. This is the first report of SLNB using ICG and PDE system for patients with previous BAS. PMID:21671037

    Purpose Sentinel lymph node resection (SNR) may reduce morbidity while providing the same clinical utility as conventional axillary dissection (AD). National Surgical Adjuvant Breast and Bowel Project (NSABP) B-32 is a randomized phase III trial comparing SNR immediately followed by AD (SNAD) to SNR and subsequent AD if SN is positive. We report the definitive patient-reported outcomes (PRO) comparisons. Patients and Methods Eligible patients had clinically node-negative, operable invasive breast cancer. The PRO substudy included all SN-negative participants enrolled May 2001 to February 2004 at community institutions in the United States (n = 749; 78% age ? 50; 87% clinical tumor size ? 2.0 cm; 84% lumpectomy; 87% white). They completed questionnaires presurgery, 1 and 2 to 3 weeks postoperatively, and every 6 months through year 3. Arm symptoms, arm use avoidance, activity limitations, and quality of life (QOL) were compared with intent-to-treat two-sample t-tests and repeated measures analyses. Results Arm symptoms were significantly more bothersome for SNAD compared with SNR patients at 6 months (mean, 4.8 v 3.0; P < .001) and at 12 months (3.6 v 2.5; P = .006). Longitudinally, SNAD patients were more likely to experience ipsilateral arm and breast symptoms, restricted work and social activity, and impaired QOL (P ? .002 all items). From 12 to 36 months, fewer than 15% of either SNAD or SNR patients reported moderate or greater severity of any given symptom or activity limitation. Conclusion Arm morbidity was greater with SNAD than with SNR. Despite considerable fears about complications from AD for breast cancer, this study demonstrates that initial problems with either surgery resolve over time. PMID:20679600

    2014-01-01

    Advances in molecular diagnostic tools have allowed the identification of lymph node micrometastasis (LNM), including isolated tumor cells, in cancer patients. While immunohistochemistry and reverse transcription-polymerase chain reaction have been used to identify LNM in patients with gastric cancer, the clinical significance of this finding remains unclear. Recently, minimally invasive treatments, such as endoscopic submucosal dissection and laparoscopic surgery, are widely performed to help improve postsurgical quality of life (QOL). However, it is important to maintain the balance between QOL and curability when making treatments decision for patients with gastric cancer. If minimally invasive surgery based on accurate intraoperative LNM diagnosis was established, it could be performed safely. Therefore, we reviewed the clinical significance of LNM detected by molecular techniques as an important target for treatment decision making with gastric cancer patients. PMID:25320510

    Our objective was to elucidate phenotypic differences between prostate cancer (PCa) liver, lymph node, and bone metastases. PCa metastases were obtained through a rapid tissue acquisition necropsy protocol. We grossly dissected metastatic foci from frozen samples and performed expression analyses using cDNA microarrays. Immunohistochemical analyses using a tissue microarray from thirty individuals with PCa metastases to lymph nodes, liver, and bone was used to confirm the gene expression changes associated with each metastatic site. Transcript alterations statistically-associated with bone metastases included increased expression of IBSP (Bone sialoprotein), F13A1 (factor XIII), and decreased expression of EFNA1 (ephrin-A1) and ANGPT2 (angiopoietin-2) when compared to liver and lymph node metastases. The metastasis-associated changes in proteins involved in coagulation and angiogenesis prompted further analysis of additional factors known to participate in the clotting cascade and blood vessel formation (angiopoitein-1, PAI-1, uPA, PAI-RBP-1 and hepsin). We also assessed tumor-associated microvessel density and distribution in liver, lymph node, and bone metastasis. Intense fibrin(ogen) and fibulin-1 staining was localized to epithelial cells at the periphery of metastatic tumors possibly to facilitate angiogenesis. The expression of hepsin, uPA, PAI-RBP1, PAI-1, and factor XIII may influence fibrinolysis and are regulated by the tumor microenvironment. The expression of angiopoietin-2 and apparent silencing of angiopoietin-1 in PCa bone, liver, and lymph node metastases may be critical for angiogenesis in this tumor type. In addition, the resulting tumor-associated microvessel density and distribution was significantly different between liver and bone metastasis possibly in response to the protein expression changes detailed above.

    Silver-stained nucleolar organizer regions (AgNORs) in human breast carcinoma were studied using a computer-assisted system of image analysis. Standardized, automatic measurements of 7 morphometric parameters (area, perimeter, shape factor, bend energy, angle, and small and large diameters) performed on paraffin sections and cell imprint were compared and correlated with nuclear morphometry, histopathological grading, tumor growth fraction, (monoclonal Ki67-immunostaining), DNA nuclear content (stoechiometric Feulgen staining) and axillary lymph node invasion. The major findings were as follows: (i) variations in AgNORs and nuclear parameters were correlated, (ii) the ratio of AgNOR area/nuclear area was significantly different in low and high grade tumors, (iii) mean AgNOR parameter values increased significantly with the tumor growth fraction and tumor hyperploidy and were significantly higher in patients with axillary lymph node metastases and (iv) AgNOR evaluation was more accurate for cell preparations than for tissue sections.

  6. Determination of standard number, size and weight of mediastinal lymph nodes in postmortem examinations: reflection on lung cancer surgery

    2013-01-01

    Background Mediastinal lymph node dissection is an essential component of lung cancer surgery. Literature lacks established information regarding the number and size of the healthy lymph nodes. In this postmortem autopsy study, we aim to define the number, size and weight of the lymph nodes in each mediastinal lymph node station. To implement the data for the clinical practice, we analyzed the possible number of nodes to be dissected in a systematic mediastinal lymph node dissection from the right and left sides during lung cancer surgery. Methods Sixty-two samples obtained from cadavers who did not die from chest malignancies, extrathoracic malignancies, any kind of infections or previous hospitalization before the death were included to the study. The locations of the nodes were recorded according to the American Thoracic Society Mediastinal Lymph Node Map. The number, size and weight of the nodes were determined at each station. Results Median age of the cadavers was 39 years. Primary causes of death were asphyxia in 10 (16.1%) subjects, trauma in 29 (46.8%) subjects, cardiovascular problems in 10 (16.1%) subjects, and undetermined in 13 (21%) subjects. The median number of lymph nodes resected from each patient was 23 (range: 11–54). The right sided paratracheal lymph nodes (Station 2R and 4R) were more frequent, heavier and longer than left sided lymph nodes (Station 2L and 4L) at the paratrecheal region. Right sided inferior mediastinal lymph nodes were heavier and longer than the left ones; however, their availability was more often on the left. Conclusions The properties of mediastinal lymph nodes at particular stations are different for number, size and weight. Station 4R and 7 have the highest number of nodes followed by stations 5 and 6. We recommend removing the lymph nodes of these stations completely in lung cancer patients to rule out the possibility of micrometastatic disease. Diameter of normal lymph node may be 1 cm for the stations other than 4R and 7, but the definition of normal diameter of a lymph node at the stations 4R and 7 may be changed as 1,5 cm and 2,0 cm, respectively. Weight of the nodes may be a new subject to study and may be defined as a new modality to define a staging to be more accurate and the issue needs further investigations. PMID:23591054

    Here, we report the establishment of a stably transfected cell line which expresses high levels of green fluorescent protein (GFP), thus permitting the detection and visualization of developing tumors and lymph node metastases after injection into nude mice. Cells of the human oral squamous carcinoma cell line (SAS-L1) were transfected with an expression vector containing a cDNA encoding humanized GFP and the neomycin resistance gene. A clone with stable high-level expression of GFP was selected in vitro using G418. To study metastasis formation, GFP-expressing cells were injected orthotopically into the tongue of nude mice. The resultant tumor growth in the tongue and micrometastases in the lymph nodes could be visualized by GFP fluorescence. Therefore a useful model has been developed for the study of oral cancer, firstly to understand the metastatic process and secondly for the evaluation of potential treatments. PMID:12167418

    2013-01-01

    Current spontaneous metastasis models require a long period of observation after establishment of primary tumors to see significant metastatic progression. The degree of metastasis is not consistent among animals: this is problematic since it requires the use of a large number of animals to obtain reliable statistics. Here we report that pre-treatment of animals with tumor-conditioned media (TCM) consistently accelerates spontaneous metastasis in breast cancer. An inguinal breast tumor model facilitated by TCM showed robust anterior metastasis to the axillary and brachial lymph nodes (LN), and the lungs compared to the serum-free media (SFM) treated group. The LN in TCM-treated animals showed enhanced angiogenesis and lymphangiogenesis. Primary tumors and lungs in TCM-treated animals showed enhanced lymphangiogenesis with no significant change in angiogenesis. TCM-treated animals also showed metastatic dissemination to abdomen from the primary injection site: this would generally enhance metastasis to other organs. In sum, the addition of TCM pre-treatment to current metastasis models results in accelerated and robust metastasis which would enable more efficient evaluation of anti-metastatic agents.

    African American women with early stage, invasive breast cancer were 12 percent less likely than Caucasian women with the same diagnosis to receive a minimally invasive technique, axillary sentinel lymph node (SLN) biopsy, years after the procedure had become the standard of surgical practice, according to research from The University of Texas MD Anderson Cancer Center. The study, presented at the 2012 CTRC-AACR San Antonio Breast Cancer Symposium, also found that those African American women who underwent the older, more invasive procedure, axillary lymph node (ALN) dissection, had higher rates of lymphedema.

    Patients with late-stage cancer commonly have distant lymph node metastasis; however, poor health often contraindicates surgical treatment. Although the quality of life and overall survival for these patients are low, there is neither a consensus nor a guide for treatment. Ablation technique and surrounding tissue damage are two possible reasons for limited study of radiofrequency ablation in patients with superficial distant lymph node metastasis. Here, we report two patients treated successfully with ultrasound-guided radiofrequency ablation for superficial distant lymph node metastasis. In these patients, deionized water was injected to the surrounding tissues of the lymph node to decrease heat injury. Results from these patients suggest that radiofrequency ablation may play an important role in the treatment of patients with distant lymph node metastasis. PMID:23544449

    2014-01-01

    Two decades ago, lymphatic mapping of sentinel lymph nodes (SLN) was introduced into surgical cancer management and was termed sentinel node navigated surgery. Although this technique is now routinely performed in the management of breast cancer and malignant melanoma, it is still under investigation for use in other cancers. The radioisotope technetium (99mTc) and vital blue dyes are among the most widely used enhancers for SLN mapping, although near-infrared fluorescence imaging of indocyanine green is also becoming more commonly used. 99mTc-tilmanocept is a new synthetic radioisotope with a relatively small molecular size that was specifically developed for lymphatic mapping. Because of its small size, 99mTc-tilmanocept quickly migrates from its site of injection and rapidly accumulates in the SLN. The mannose moieties of 99mTc-tilmanosept facilitate its binding to mannose receptors (CD206) expressed in reticuloendothelial cells of the SLN. This binding prevents transit to second-echelon lymph nodes. In Phase III trials of breast cancer and malignant melanoma, and Phase II trials of other malignancies, 99mTc-tilmanocept had superior identification rates and sensitivity compared with blue dye. Trials comparing 99mTc-tilmanocept with other 99mTc-based agents are required before it can be routinely used in clinical settings. PMID:25028560

    A 62-year-old patient with prostate adenocarcinoma underwent PET with radiolabeled choline (F-Fcholine) for pretreatment staging of a high-risk prostate cancer. Images showed a significant mediastinal lymph node uptake of F-Fcholine. Owing to the rarity of spread to supradiaphragmatic lymph nodes, a surgical removal was performed, revealing anthracosis and no malignant cells. Even if its specificity seems better than F-FDG, false positives have been reported and other pathologies could mimic lymph node metastases. Consequently, histology should be performed so that the appropriate treatment can be initiated. PMID:25674859

    Accurate preoperative staging and restaging of mediastinal lymph nodes in patients with potentially resectable non-small-cell lung cancer (NSCLC) is of paramount importance. In 2007, the European Society of Thoracic Surgeons (ESTS) published an algorithm on preoperative mediastinal staging integrating imaging, endoscopic and surgical techniques. In 2009, the International Association for the Study of Lung Cancer (IASLC) introduced a new lymph node map. Some changes in this map have an important impact on mediastinal staging. Moreover, more evidence of the different mediastinal staging technique has become available. Therefore, a revision of the ESTS guidelines was needed. In case of computed tomography (CT)-enlarged or positron emission tomography (PET)-positive mediastinal lymph nodes, tissue confirmation is indicated. Endosonography [endobronchial ultrasonography (EBUS)/esophageal ultrasonography (EUS)] with fine-needle aspiration (FNA) is the first choice (when available), since it is minimally invasive and has a high sensitivity to rule in mediastinal nodal disease. If negative, surgical staging with nodal dissection or biopsy is indicated. Video-assisted mediastinoscopy is preferred to mediastinoscopy. The combined use of endoscopic staging and surgical staging results in the highest accuracy. When there are no enlarged lymph nodes on CT and when there is no uptake in lymph nodes on PET or PET-CT, direct surgical resection with systematic nodal dissection is indicated for tumours ? 3 cm located in the outer third of the lung. In central tumours or N1 nodes, preoperative mediastinal staging is indicated. The choice between endoscopic staging with EBUS/EUS and FNA or video-assisted mediastinoscopy depends on local expertise to adhere to minimal requirements for staging. For tumours >3 cm, preoperative mediastinal staging is advised, mainly in adenocarcinoma with high standardized uptake value. For restaging, invasive techniques providing histological information are advisable. Both endoscopic techniques and surgical procedures are available, but their negative predictive value is lower compared with the results obtained in baseline staging. An integrated strategy using endoscopic staging techniques to prove mediastinal nodal disease and mediastinoscopy to assess nodal response after induction therapy needs further study. PMID:24578407

  15. Role of FDG PET-CT in evaluation of locoregional nodal disease for initial staging of breast cancer

    2014-01-01

    Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) is not indicated or recommended in the initial staging of early breast cancer. Although it is valuable for detecting distant metastasis, providing prognostic information, identifying recurrence and evaluating response to chemotherapy, the role of FDG PET/CT in evaluating locoregional nodal status for initial staging of breast cancer has not yet been well-defined in clinical practice. FDG PET/CT has high specificity but compromised sensitivity for identifying axillary nodal disease in breast cancer. Positive axillary FDG PET/CT is a good predictor of axillary disease and correlates well with sentinel lymph node biopsy (SLNB). FDG PET/CT may help to identify patients with high axillary lymph node burden who could then move directly to axillary lymph node dissection (ALND) and would not require the additional step of SLNB. However, FDG PET/CT cannot replace SLNB or ALND due to unsatisfactory sensitivity. The spatial resolution of PET instruments precludes the detection of small nodal metastases. Although there is still disagreement regarding the management of internal mammary node (IMN) disease in breast cancer, it is known that IMN involvement is of prognostic significance, and IMN metastasis has been associated with higher rates of distant metastasis and lower overall survival rates. Limited clinical observations suggested that FDG PET/CT has advantages over conventional modalities in detecting and uncovering occult extra-axillary especially IMN lesions with upstaging the disease and an impact on the adjuvant management.

    Purpose: Large studies examining the clinical and pathological factors associated with nodal metastasis in minor salivary gland cancer are lacking in the literature. Methods and Materials: Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified 2,667 minor salivary gland cancers with known lymph node status from 1988 to 2004. Univariate and multivariate analyses were conducted to identify factors associated with the use of neck dissection, the use of external beam radiation therapy, and the presence of cervical lymph node metastases. Results: Four hundred twenty-six (16.0%) patients had neck nodal involvement. Factors associated with neck nodal involvement on univariate analysis included increasing age, male sex, increasing tumor size, high tumor grade, T3-T4 stage, adenocarcinoma or mucoepidermoid carcinomas, and pharyngeal site of primary malignancy. On multivariate analysis, four statistically significant factors were identified, including male sex, T3-T4 stage, pharyngeal site of primary malignancy, and high-grade adenocarcinoma or high-grade mucoepidermoid carcinomas. The proportions (and 95% confidence intervals) of patients with lymph node involvement for those with 0, 1, 2, 3, and 4 of these prognostic factors were 0.02 (0.01-0.03), 0.09 (0.07-0.11), 0.17 (0.14-0.21), 0.41 (0.33-0.49), and 0.70 (0.54-0.85), respectively. Grade was a significant predictor of metastasis for adenocarcinoma and mucoepidermoid carcinoma but not for adenoid cystic carcinoma. Conclusions: A prognostic index using the four clinicopathological factors listed here can effectively differentiate patients into risk groups of nodal metastasis. The precision of this index is subject to the limitations of SEER data and should be validated in further clinical studies.

    Treatment of cervical cancer, one of the three most commonly diagnosed cancers worldwide, often relies on delineations of the tumour and metastases based on PET imaging using the contrast agent 18F-Fluorodeoxyglucose (FDG). We present a robust automatic algorithm for segmenting the gross tumour volume (GTV) and metastatic lymph nodes in such images. As the cervix is located next to the bladder and FDG is washed out through the urine, the PET-positive GTV and the bladder cannot be easily separated. Our processing pipeline starts with a histogram-based region of interest detection followed by level set segmentation. After that, morphological image operations combined with clustering, region growing, and nearest neighbour labelling allow to remove the bladder and to identify the tumour and metastatic lymph nodes. The proposed method was applied to 125 patients and no failure could be detected by visual inspection. We compared our segmentations with results from manual delineations of corresponding MR and CT images, showing that the detected GTV lays at least 97.5% within the MR/CT delineations. We conclude that the algorithm has a very high potential for substituting the tedious manual delineation of PET positive areas.

    ABSTRACT When dealing with patients who have head and neck cancer - squamous cell carcinoma and have clinically N0 neck disease it is very difficult to assess the real extension of the malignant proccess. This is why several techniques are curently in use to determine the actual TNM clasiffication for each patient in order to apply best suited therapy management. Up until today the staging of the neck has been done by using a combination of the physical exam and conventional imaging studies. Recent studies and research have tried to determine weather the use of sentinel lymph node biopsy is a more reliable tool in predicting occult metastasis in cancer patients with clinically N0 neck disease. There are no guidelines in this matter and as such the use of the sentinel lymph node detection technique is yet to be used on a routine basis. The authors are trying to assess the benefits of different paraclinical investigation regarding the improvement of overall survival rates in patients with T1/T2 squamous cell carcinoma of the head and neck and N0 neck disease.

    We investigated whether gene expression profiling of primary cervical tumor tissue could be used to predict lymph node (LN) metastasis and compared this with conventional magnetic resonance imaging. We obtained 43 primary cervical cancer samples (16 with LN metastasis and 27 without LN metastasis) for microarray analysis. A prediction model for LN metastasis from the training set was developed by support vector machine methods using a 10-fold cross-validation. The 'LN prediction model' derived from the signature of 156 distinctive genes (P < 0.01) had a prediction accuracy of 77%. Correlation between mRNA expressions measured by microarray and semiquantitative reverse transcription-polymerase chain reaction was ascertained in four (RBM8A, SDHB, SERPINB13, and gamma-interferon) out of 10 genes. Magnetic resonance imaging showed accuracy (69%) for the prediction of LN metastasis. These results suggest that gene expression profiling allows reliable prediction of LN metastasis in cervical cancer. PMID:17986283

    Background The aim of this study was to explore a new method to identify and protect parathyroid glands in neck lymph node dissection for patients with thyroid cancer. Material/Methods One hundred patients with thyroid cancer underwent total thyroidectomy combined with central neck lymph node dissection. During the operation, 50 patients receiving nano-carbon suspension were included in the experiment group, and 50 patients without nano-carbon suspension were included in the control group. We compared changes in parathyroid hormone levels before surgery and at 48 h after surgery between the 2 groups and of serum Ca2+ level within 48 h after surgery, as well as postoperative parathyroid pathological and lymph node dissection results. Results Eight and 1 parathyroid glands were detected pathologically in the control and experimental group, respectively. Decrease in parathyroid hormone level at 48 h occurred in 7 patients in the control group and 1 patient in the experimental group. Hypocalcemia was found at 48 h after surgery in 10 patients in the control group and 2 patients in the experimental group. Conclusions Nano-carbon suspension can cause development of the thyroid gland and the central lymph node and a negative development of parathyroid glands. Careful identification and removal of black-stained lymphatic tissues in the process of total thyroidectomy with neck lymph node dissection can ensure a complete lymph node dissection and prevent parathyroid damage, thus effectively reducing the incidence of hypoparathyroidism.

    Background Sentinel lymph nodes (SLNs) have been used to predict regional lymph node metastasis in patients with melanoma and breast cancer. However, the validity of the SLN hypothesis is still controversial for oesophageal cancer. We performed this meta-analysis to evaluate the feasibility and accuracy of radio-guided SLN mapping for oesophageal cancer. Methods A systematic search was conducted using MEDLINE, PubMed, EMBASE, Current Contents Connect, Cochrane library, Google scholar, Science Direct, and Web of Science. Original data was abstracted from each study and used to calculate a pooled event rates and 95% confidence interval (95% CI). Results The search identified 23 relevant articles. The overall detection rate was 0.93 (95% CI: 0.894-0.950), sensitivity 0.87 (95% CI: 0.811-0.908), negative predictive value 0.77 (95% CI: 0.568-0.890) and the accuracy was 0.88 (95% CI: 0.817-0.921). In the adenocarcinoma cohort, detection rate was 0.98 (95% CI: 0.923-0.992), sensitivity 0.84 (95% CI: 0.743-0.911) and the accuracy was 0.87(95% CI: 0.796-0.913). In the squamous cell carcinoma group, detection rate was 0.89 (95% CI: 00.792-0.943), sensitivity 0.91 (95% CI: 0.754-0.972) and the accuracy was 0.84 (95% CI: 0.732-0.914). Conclusions It is possible to identify and obtain a SLN before neoadjuvant therapy in oesophageal cancer. However, further work is needed to optimize radiocolloid type, refine the technique and develop a quick and accurate way to determine SLN status intraoperatively. This technique has to be further evaluated before it can be applied widely. PMID:24772341

    We experienced a rare case of isolated lateral lymph node (LLN) recurrence after laparoscopic intersphincteric resection with total mesorectal excision for T1 lower rectal cancer that was successfully treated using LLN dissection with en bloc resection of the left superior vesical artery, the left ovary and the left obturator nerve, artery and vein. There are no guidelines for treating patients with isolated LLN recurrence because isolated LLN recurrence is rare, especially in patients with T1 rectal cancer. However, in patients with pT1N0 lower rectal cancer, follow-up examinations of the pelvis should be performed periodically. Patients with isolated LLN recurrence treated with surgery might have good long-term prognoses. Therefore, for such patients, surgical resection should be considered as a curative treatment only.

    Lymph node metastasis (LNM) in gastric cancer is associated with higher rate of cancer recurrence and poor prognosis. As a result, a reliable biomarker for the prediction of LNM is important and would be valuable in the clinical practice. MiRNA microarray revealed that ten miRNAs were expressed significantly different among patients with or without LNM. A total of 46 gastric cancer patients were enrolled and divided into two groups (23 in each group) according to the presence or absence of LNM. RT-PCR of these 10 miRNAs was investigated and compared between the two groups. MiR-1207-5p was significantly upregulated in gastric cancer patients without LNM compared with those with LNM. Patients with upregulated miR-1207-5p had less scirrhous stromal reaction, less lymphovascular invasion, and earlier pathological T category, N category, and TNM stage, compared with those with downregulated or unchanged miR-1207-5p. Multivariate analysis showed that stromal reaction type, lymphovascular invasion, pathological T category and TNM stage, and expression of miR-1207-5p were independent risk factors of LNM. MiR-1207-5p could serve as a useful biomarker in the prediction of LNM in gastric cancer. PMID:25688358

    Purpose: The Roach formula [2/3 Multiplication-Sign prostate-specific antigen + (Gleason score - 6) Multiplication-Sign 10], derived in 1993 during the early prostate specific antigen (PSA) screening era, has been used to predict the risk of pelvic lymph node involvement in patients with prostate cancer. In the current era of widespread PSA screening with a shift to earlier disease stages, there is evidence to suggest that the Roach score overestimates risk of nodal metastasis. This study retrospectively reviews the validity of this formula as a prediction tool. Methods and Materials: We conducted a retrospective institutional review including men with clinical T1c-T3 prostate cancer, with baseline PSA levels and biopsy-obtained Gleason scores who underwent radical prostatectomy with pelvic node dissection from 2001 through 2009 (N = 1,022). The predicted risk of nodal involvement was calculated for each patient using the Roach formula and then compared with actual rates following surgery. Results: The study included 1,022 patients; 99.6% had clinical T1c/T2 disease, with a mean of 10.3 lymph nodes surgically evaluated. Overall, 42 patients (4.1%) had nodal metastasis. For every range of scores, the Roach formula overestimates the risk of nodal involvement. Observed nodal positivity was 1%, 6.3%, 10%, 15.2%, and 16.7% for Roach scores {<=}10%, >10%-20%, >20%-30%, >30%-40%, and >40%, respectively. The Roach score overestimates the risk by approximately 4.5-fold in patients with scores {<=}10%, by 2.5-fold for all scores between 10% and 40%, and by 4-fold for scores >40%. Conclusion: The Roach formula overpredicts the risk of pelvic nodal involvement in current-era prostate cancer patients undergoing regular PSA screening and with mainly T1c/T2 disease. Contemporary patients are much less likely to have nodal involvement for a given PSA and Gleason score.

    Papillary thyroid cancer (PTC) is the most rapidly increasing endocrine malignancy worldwide. Although less aggressive than the majority malignancies, PTC exhibits extensive cervical lymph node metastasis in early stage of PTC. However, the underlying molecular mechanism of this early-metastasis remains unknown. Toll like receptors (TLRs) constitute a crucial component of the innate immune response to bacterial and viral pathogens. Emerging evidence suggests that TLRs play important roles in cancer progression, invasion and immune evasion, whereas whether TLRs have any role in PTC remains to be clarified. In this study, we found that TLR3 was present in both PTC specimen and various thyroid cancer cell lines. Further IHC analysis of 63 PTC patients revealed that TLR3 expression was associated with cervical metastasis, but not correlated with patients’ TNM staging, extrathyroidal invasion. In addition, TLR3 promoted migration of K1 cells in vitro. Activation of TLR3 increased cancer stem cell marker and migration promoting CD44 expression in vitro, indicating that TLR3 might promote metastasis of PTC via modulating CD44 expression. Taken together, our data revealed that TLR3 is correlated with cervical metastasis of PTC and might be an essential prognostic indicator and target for PTC metastasis. PMID:25664012

    Malignant tumors of ectodermal or endodermal origin may metastasize to the sentinel lymph node, the first lymph node encountered by tumor cells that enter lymphatics in the organ of origin. This pathway is enabled by the anatomy of the disease and the causes of metastasis are the result of complex interactions that include mechanical forces within the tumor and host tissues, and molecular factors initiated by tumor cell proliferation, elaboration of cytokines and changes in the tumor microenvironment. Mechanical stresses may influence complex biochemical, genetic and other molecular events and enhance the likelihood of metastasis. This paper summarizes our understanding of interacting molecular, anatomical and mechanical processes which facilitate metastasis to SLNs. Our understanding of these interacting events is based on a combination of clinical and basic science research, in vitro and in vivo, including studies in lymphatic embryology, anatomy, micro-anatomy, pathology, physiology, molecular biology and mechanobiology. The presence of metastatic tumor in the SLN is now more accurately identifiable and, based upon prospective clinical trials, paradigm-changing SLN biopsy has become the standard of clinical practice in breast cancer and melanoma.

    A technique for high dose (5600-6100 cGy) extended field irradiation to the para-aortic lymph nodes is described. Fourteen patients have been treated with this technique, of whom 10 have had histologic confirmation of para-aortic node metastases. With follow-up ranging from 11 to 78 months, 7 of 14 patients are alive and clinically cancer-free. Acute effects of extended field treatment on patient weight and circulating blood counts are analyzed, and late treatment morbidity assessed. The findings suggest that such treatment, executed with modern equipment and appropriate technique, is not significantly more hazardous than pelvic irradiation, and can result in a substantial probability of disease-free survival.

    Background: Women with node-positive vulvar cancer have a high risk for disease recurrence. Indication criteria for adjuvant radiotherapy are controversial. This study was designed to further understand the role of adjuvant therapy in node-positive disease. Methods: Patients with primary squamous-cell vulvar cancer treated at 29 gynecologic cancer centers in Germany from 1998 through 2008 were included in this retrospective exploratory multicenter cohort study. Of 1618 documented patients, 1249 had surgical groin staging and known lymph node status and were further analyzed. All statistical tests were two-sided. Results: Four hundred forty-seven of 1249 patients (35.8%) had lymph node metastases (N+). The majority of N+ patients had one (172 [38.5%]) or two (102 [22.8%]) positive nodes. The three-year progression-free survival (PFS) rate of N+ patients was 35.2%, and the overall survival (OS) rate 56.2% compared with 75.2% and 90.2% in node-negative patients (N-). Two hundred forty-four (54.6%) N+ patients had adjuvant therapy, of which 183 (40.9%) had radiotherapy directed at the groins (+/-other fields). Three-year PFS and OS rates in these patients were better compared with N+ patients without adjuvant treatment (PFS: 39.6% vs 25.9%, hazard ratio [HR] = 0.67, 95% confidence interval [CI[= 0.51 to 0.88, P = .004; OS: 57.7% vs 51.4%, HR = 0.79, 95% CI = 0.56 to 1.11, P = .17). This effect was statistically significant in multivariable analysis adjusted for age, Eastern Cooperative Oncology Group, Union internationale contre le cancer stage, grade, invasion depth, and number of positive nodes (PFS: HR = 0.58, 95% CI = 0.43 to 0.78, P < .001; OS: HR = 0.63, 95% CI = 0.43 to 0.91, P = .01). Conclusion: This large multicenter study in vulvar cancer observed that adjuvant radiotherapy was associated with improved prognosis in node-positive patients and will hopefully help to overcome concerns regarding adjuvant treatment. However, outcome after adjuvant radiotherapy remains poor compared with node-negative patients. Adjuvant chemoradiation could be a possible strategy to improve therapy because it is superior to radiotherapy alone in other squamous cell carcinomas. PMID:25618900

    Qualified radical gastrectomy with lymph node dissection is very important to the prognosis of patients with gastric cancer. Now D2 lymph node dissection is standard procedure for gastric cancer surgery, and spleen hilar lymph node dissection is mandatory for gastric cancer in upper body. Because the anatomy of vessels in this area is very complicated, D2 lymph node dissection is technical challenging not only for open gastrectomy but also for laparoscopic one. Adapting a new technique is important to all surgeons, but we surgeons should always consider a patient's safety as the most important factor during surgery and that efforts should be based on scientific rationale with oncologic principles. I hope that the recent report by Huang et al. about laparoscopic spleen preserving hilar lymph node dissection would be helpful to young surgeons who will perform laparoscpic total gastrectomy for gastric cancer.

    Purpose: To evaluate the outcome of robotic CyberKnife (Accuray, Sunnyvale, CA)-based stereotactic radiotherapy (CBK-SRT) for isolated recurrent primary, lymph node, or metastatic prostate cancer. Methods and Materials: Between May 2007 and December 2009, 34 consecutive patients/38 lesions were treated (15 patients reirradiated for local recurrence [P], 4 patients reirradiated for anastomosis recurrence [A], 16 patients treated for single lymph node recurrence [LN], and 3 patients treated for single metastasis [M]). In all but 4 patients, [{sup 11}C]choline positron emission tomography/computed tomography was performed. CBK-SRT consisted of reirradiation and first radiotherapy in 27 and 11 lesions, respectively. The median CBK-SRT dose was 30 Gy in 4.5 fractions (P, 30 Gy in 5 fractions; A, 30 Gy in 5 fractions; LN, 33 Gy in 3 fractions; and M, 36 Gy in 3 fractions). In 18 patients (21 lesions) androgen deprivation was added to CBK-SRT (median duration, 16.6 months). Results: The median follow-up was 16.9 months. Acute toxicity included urinary events (3 Grade 1, 2 Grade 2, and 2 Grade 3 events) and rectal events (1 Grade 1 event). Late toxicity included urinary events (3 Grade 1, 2 Grade 2, and 2 Grade 3 events) and rectal events (1 Grade 1 event and 1 Grade 2 event). Biochemical response was observed in 32 of 38 evaluable lesions. Prostate-specific antigen stabilization was seen for 4 lesions, and in 2 cases prostate-specific antigen progression was reported. The 30-month progression-free survival rate was 42.6%. Disease progression was observed for 14 lesions (5, 2, 5, and 2 in Groups P, A, LN, and M respectively). In only 3 cases, in-field progression was seen. At the time of analysis (May 2010), 19 patients are alive with no evidence of disease and 15 are alive with disease. Conclusions: CyberKnife-based stereotactic radiotherapy is a feasible approach for isolated recurrent primary, lymph node, or metastatic prostate cancer, offering excellent in-field tumor control and a low toxicity profile. Further investigation is warranted to identify the patients who benefit most from this treatment modality. The optimal combination with androgen deprivation should also be defined.

Cell-stroma interactions guide the development and generation of tumors. Here, we evaluate the contributions of normal fibroblasts to gastric cancer. Methodology/Principal Findings By coculturing normal fibroblasts in monolayers of BGC-823 gastric cancer cells, tumor cells sporadically developed short, spindle-like morphological characteristics and demonstrated enhanced proliferation and invasive potential. Furthermore, the transformed tumor cells demonstrated decreased tumor formation and increased lymphomatic and intestinal metastatic potential. Non-transformed BGC-823 cells, in contrast, demonstrated primary tumor formation and delayed intestinal and lymph node invasion. We also observed E-cadherin loss and the upregulation of vimentin expression in the transformed tumor cells, which suggested that the increase in metastasis was induced by epithelial-to-mesenchymal transition. Conclusion Collectively, our data indicated that normal fibroblasts sufficiently induce epithelial-to-mesenchymal transition in cancer cells, thereby leading to metastasis. PMID:24845259

    Surgical resection remains the essential part in the curative treatment of gastric cancer. However, with surgery only, long-term survival is poor (5-year survival <25 % in Europe). Randomized studies, which compared limited (D1) lymph node dissection with more extended (D2) resections in the Western world, failed to show a survival benefit for more extensive surgery. A substantial increase in survival was found with perioperative chemotherapy in the MAGIC study. In addition, the SWOG/Intergroup 0116 study showed that postoperative chemoradiotherapy (CRT) prolonged 5-year overall survival compared to surgery only. However, it has been argued that surgical undertreatment undermined survival in this trial. In a randomized Korean study, patients with advanced stage gastric cancer who received postoperative CRT had better outcome after a D2 dissection. At our institute phase I-II studies with adjuvant cisplatin and capecitabine-based CRT have been performed in over 120 patients with resected gastric cancer. Retrospective comparison of patients treated in these studies with those that had surgery only in the D1D2 study, demonstrated that postoperative CRT was associated with better outcome, especially after D1 or a R1 resection. For daily practice, it remains unclear whether patients after optimal (D2) gastric surgery will benefit from postoperative CRT. This is currently being tested in prospective randomized phase III trials (CRITICS; TOPGEAR). PMID:23129378

    Sentinel lymph node (SLN) mapping accurately diagnoses the status of nodal basin with >95% accuracy in melanoma and breast cancer. A multicenter trial for SLN mapping was performed on 203 patients with colorectal cancer to determine accuracy, upstaging, skip metastasis, and aberrant drainage. Lymphazurin 1% was injected subserosally around the tumor and 1-4 blue staining nodes were marked as SLNs for detailed histological analysis. SLN mapping was successful in 98% of patients with an average of 1.7 SLNs per patient. SLNs were negative in 63% of the patients and positive in 37% of the patients. Skip metastasis was seen in 8 of the patients. Occult micrometastasis was found in 14% of patients. In 5% of the patients, unusual lymphatic drainage lead to an alteration of the extent of lymphadenectomy. This multicenter trial proved that SLN mapping in patients with colorectal cancer is simple, cost effective, and upstages at least 14% of patients from AJCC stage I/II to stage III. These patients may then benefit from adjuvant chemotherapy. PMID:11599912

    Near-infrared (NIR) fluorescence imaging using indocyanine green (ICG) has the potential to improve the sentinel lymph node (SLN) procedure by facilitating percutaneous and intraoperative identification of lymphatic channels and SLNs. Previous studies suggested that a dose of 0.62 mg (1.6 mL of 0.5 mM) ICG is optimal for SLN mapping in breast cancer. The aim of this study was to evaluate the diagnostic accuracy of NIR fluorescence for SLN mapping in breast cancer patients when used in conjunction with conventional techniques. Study subjects were 95 breast cancer patients planning to undergo SLN procedure at either the Dana-Farber/Harvard Cancer Center (Boston, MA, USA) or the Leiden University Medical Center (Leiden, the Netherlands) between July 2010 and January 2013. Subjects underwent the standard-of-care SLN procedure at each institution using (99)Technetium-colloid in all subjects and patent blue in 27 (28 %) of the subjects. NIR fluorescence-guided SLN detection was performed using the Mini-FLARE imaging system. SLN identification was successful in 94 of 95 subjects (99 %) using NIR fluorescence imaging or a combination of both NIR fluorescence imaging and radioactive guidance. In 2 of 95 subjects, radioactive guidance was necessary for initial in vivo identification of SLNs. In 1 of 95 subjects, NIR fluorescence was necessary for initial in vivo identification of SLNs. A total of 177 SLNs (mean 1.9, range 1-5) were resected: 100 % NIR fluorescent, 88 % radioactive, and 78 % (of 40 nodes) blue. In 2 of 95 subjects (2.1 %), SLNs-containing macrometastases were found only by NIR fluorescence, and in one patient this led to upstaging to N1. This study demonstrates the safe and accurate application of NIR fluorescence imaging for the identification of SLNs in breast cancer patients, but calls into question what technique should be used as the gold standard in future studies.

    Background Lymph node metastasis is a key event in the progression of breast cancer. Therefore it is important to understand the underlying mechanisms which facilitate regional lymph node metastatic progression. Methodology/Principal Findings We performed gene expression profiling of purified tumor cells from human breast tumor and lymph node metastasis. By microarray network analysis, we found an increased expression of polycomb repression complex 2 (PRC2) core subunits EED and EZH2 in lymph node metastatic tumor cells over primary tumor cells which were validated through real-time PCR. Additionally, immunohistochemical (IHC) staining and quantitative image analysis of whole tissue sections showed a significant increase of EZH2 expressing tumor cells in lymph nodes over paired primary breast tumors, which strongly correlated with tumor cell proliferation in situ. We further explored the mechanisms of PRC2 gene up-regulation in metastatic tumor cells and found up-regulation of E2F genes, MYC targets and down-regulation of tumor suppressor gene E-cadherin targets in lymph node metastasis through GSEA analyses. Using IHC, the expression of potential EZH2 target, E-cadherin was examined in paired primary/lymph node samples and was found to be significantly decreased in lymph node metastases over paired primary tumors. Conclusions/Significance This study identified an over expression of the epigenetic silencing complex PRC2/EED-EZH2 in breast cancer lymph node metastasis as compared to primary tumor and its positive association with tumor cell proliferation in situ. Concurrently, PRC2 target protein E-cadherin was significant decreased in lymph node metastases, suggesting PRC2 promotes epithelial mesenchymal transition (EMT) in lymph node metastatic process through repression of E-cadherin. These results indicate that epigenetic regulation mediated by PRC2 proteins may provide additional advantage for the outgrowth of metastatic tumor cells in lymph nodes. This opens up epigenetic drug development possibilities for the treatment and prevention of lymph node metastasis in breast cancer. PMID:23251464

    Sleeve lobectomy for selected cases of central lung cancer has better functional outcomes comparing to pneumonectomy. With improved technology and increased experiences in complete video-assisted thoracic surgery (VATS) lobectomy, complete VATS sleeve lobectomy has been applied in major medical centers recently. A 64-year-old male patient with left lower central lung cancer underwent thoracoscopic sleeve lobectomy and systemic mediastinal lymph node dissection. The major incision, of four incisions in total, was a 4 cm mini-incision in the 4th intercostal space of anterior axillary line. The patient had recovered uneventfully after the surgery.

    In spite of recent advances in diagnostic tools such as computed tomography, endoscopic ultrasonography, and positron-emission tomography, preoperative diagnosis of lymph node metastases in patients with upper gastrointestinal (GI) cancer has been problematic because of the low sensitivity and accuracy in the detection of micrometastases. To overcome this issue, the sentinel node (SN) concept has attracted attention in recent years and is anticipated to become a novel diagnostic tool for the identification of clinically undetectable lymph node metastases in patients with early upper GI cancer. For early-stage gastric cancer, in which a better prognosis can generally be achieved using conventional surgical approaches, individualized, minimally invasive gastrectomy based on a combination of laparoscpic surgery with SN navigation surgery should be established as the next surgical milestone. Several issues remain to be resolved in laparoscopic gastrectomy with three-dimensional computed tomography navigation. PMID:18409586

    We describe the incorporation of a single-fiber reflectance spectroscopy probe into the endoscopic ultrasound fine-needle aspiration (EUS-FNA) procedure utilized for lung cancer staging. A mathematical model is developed to extract information about the physiological and morphological properties of lymph tissue from single-fiber reflectance spectra, e.g., microvascular saturation, blood volume fraction, bilirubin concentration, average vessel diameter, and Mie slope. Model analysis of data from a clinical pilot study shows that the single-fiber reflectance measurement is capable of detecting differences in the physiology between normal and metastatic lymph nodes. Moreover, the clinical data show that probe manipulation within the lymph node can perturb the in vivo environment, a concern that must be carefully considered when developing a sampling strategy. The data show the feasibility of this novel technique; however, the potential clinical utility has yet to be determined.

    Background Previous epidemiologic studies have reported that a history of allergy is associated with reduced risk of colorectal cancer and other malignancies. However, no information is available for the association between allergy and the risk of lymph node metastasis. Our study was designed to determine this association in rectal cancer. Methods Patients who were treated at our hospital in the period from January 2003 to June 2011, and with a pathologically hospital discharge diagnosis of rectal adencarcinoma, were included. The clinical, laboratory, and pathologic parameters were analyzed. A multivariate logistic regression model was used to determine the association. Moreover, for type of allergic drug, sub-group analysis was performed. Results 469 patients were included, including 231 with pathological lymph node metastasis (pLNM) (49.3%) and 238 without pLNM. Univariate analysis showed, compared with patients without pLNM, patients with pLNM had a younger age (60.6±12.8 yr vs. 63.6±12.2 yr, P?=?0.012), a lower percentage of drug allergy (8.7% vs. 16.0%, P?=?0.016), an increased CEA (median/interquartile-range 5.40/2.40–13.95 vs. 3.50/2.08–8.67, P?=?0.009), and a lower serum sodium (141±3.1 mmol/L vs. 142±2.9 mmol/L, P?=?0.028). Multivariate analysis showed that drug allergy was associated with a reduced risk of pLNM (OR?=?0.553; 95% CI, 0.308–0.994; P?=?0.048). In addition, our results showed that: (1) for tumor classification, patients with drug allergy had a higher percentage of group patients with pT1/pT2; and (2) for type of allergic drug, this inverse association was found for penicillins, not for other allergic drugs. Conclusion Drug allergy is associated with a reduced risk of pLNM in rectal cancer. PMID:25162236

    Purpose: To determine the planning results and acute toxicity after hypofractionated intensity-modulated arc radiotherapy and androgen deprivation for lymph node metastasized (Stage N1) prostate cancer. Methods and Materials: A total of 31 patients with Stage T1-T4N1M0 prostate cancer were treated with intensity-modulated arc radiotherapy and 3 years of androgen deprivation as primary treatment. The clinical target volume (CTV{sub p}) was the prostate and seminal vesicles. Elective lymph node areas ({sub e}) were delineated and expanded by 2 mm to create the CTV{sub e}. The planning target volumes (PTV{sub p} and PTV{sub e}) were created using a three-dimensional expansion of the CTV{sub p} and CTV{sub e}, respectively, of 7 mm. A median dose of 69.3 Gy and 50 Gy was prescribed to the PTV{sub p} and PTV{sub e} respectively, to be delivered in 25 fractions. Upper and lower gastrointestinal toxicity was scored using the Radiation Therapy Oncology Group toxicity and radiotherapy-induced lower intestinal toxicity scoring system. Genitourinary toxicity was scored using a combined Radiation Therapy Oncology Group, LENT-SOMA (late effects normal tissue-subjective, objective, management, analytic), and Common Toxicity Criteria toxicity scoring system. Results: The median follow-up time was 3 months. The mean prescription dose to the CTV{sub p} and PTV{sub p} was 70.4 Gy and 68.6 Gy, respectively. The minimal dose to the CTV{sub e} and PTV{sub e} was 49.0 Gy and 47.0 Gy, respectively. No acute Grade 2 or greater gastrointestinal toxicity occurred. Fourteen patients developed acute Grade 2 lower gastrointestinal toxicity. Acute Grade 3 and 2 genitourinary toxicity developed in 2 and 14 patients, respectively. Conclusion: The results of our study have shown that hypofractionated intensity-modulated arc radiotherapy as primary therapy for N1 prostate cancer is feasible with low toxicity.

    Sentinel lymph node biopsy (SLNB) has emerged as an accurate, less invasive alternative to axillary lymph node dissection, and it has rapidly become the standard of care for patients with clinically node-negative breast cancer. The sentinel lymph node (SLN) hypothesis states that the pathological status of the axilla can be accurately predicted by determining the status of the first (i.e., sentinel) lymph nodes that drain from the primary tumor. Physicians use radio-labeled sulfur colloid and/or methylene blue dye to identify the SLN, which is most likely to contain metastatic cancer cells. However, the surgical procedure causes morbidity and associated expenses. To overcome these limitations, we developed a dual-modality photoacoustic and ultrasound imaging system to noninvasively detect SLNs based on the accumulation of methylene blue dye. Ultimately, we aim to guide percutaneous needle biopsies and provide a minimally invasive method for axillary staging of breast cancer. The system consists of a tunable dye laser pumped by a Nd:YAG laser, a commercial ultrasound imaging system (Philips iU22), and a multichannel data acquisition system which displays co-registered photoacoustic and ultrasound images in real-time. Our clinical results demonstrate that real-time photoacoustic imaging can provide sensitive and specific detection of methylene blue dye in vivo. While preliminary studies have shown that in vivo detection of SLNs by using co-registered photoacoustic and ultrasound imaging is feasible, further investigation is needed to demonstrate robust SLN detection.

    The de facto standard treatment for early gastric stump cancer (GSC) has been total gastrectomy combined with radical lymph node dissection. However, some patients could benefit if partial resection of the gastric stump is feasible. We investigated the feasibility of subtotal gastrectomy for early GSC as less invasive surgery. Subtotal gastrectomy was defined as a segmental resection of the gastric remnant including the anastomosis with limited lymph node dissection. A total of 66 patients with early GSC were enrolled and 24 patients (36.4 %) underwent subtotal gastrectomy (SG group). Clinicopathological characteristics were analyzed along with those of the other 42 patients (63.6 %) who underwent total gastrectomy (TG group). There were no significant differences between the two groups in the number of lymph nodes harvested (p = 0.880). Lymph node involvement was detected in 2 patients (8.3 %) in SG group and 5 patients (11.9 %) in TG group (p = 1.000). The previous disease (benign or malignant) and surgery (Billroth I or II) did not affect the rate of nodal involvement. The 5-year overall survival rate of SG group (94.7 %) was acceptable. Subtotal gastrectomy of the gastric remnant could be a feasible treatment option for patients with early gastric stump cancer when indicated. PMID:24944156

    Echinococcosis (hydatid disease) is a zoonosis caused by the larval stage of Echinococcus granulosus (or Taenia echinococcus). The adult form of the parasite lives in the gut of the dog, while the intermediate hosts, where the tapeworm develops to larval stage are cats, cattle, pigs and humans(considered to be accidental intermediate hosts). The parasite has a worldwide distribution, but the endemic areas are Canada and Alaska, Australia, New Zealand, South America and the Mediterranean region. Hydatid cyst can grow many years before the symptoms and clinical signs appear. The liver and the lungs are the most affected organs, but primary location of the hydatid disease in the axilla is extremely rare. In our country we did not find any records of axillary hydatid disease, while the literature contains only 12 cases of axillary location. We present the case of a woman, 60 years old, with a primary axillary location of hydatid cyst, who underwent a total cystectomy. PMID:25149625

    AIM: To evaluate the predictive value of the lymph node (LN) ratio (LNR, number of metastatic LNs/ examined LNs) for recurrence in patients with rectal cancer and to compare its applicability according to preoperative chemoradiotherapy (PCRT). METHODS: From 2000 to 2009, 967 patients with metastatic LNs after curative resection for locally advanced rectal cancer were identified. Patients were categorized according to PCRT (PCRT vs No PCRT). The cut-off LNR was determined based on the pN1 vs pN2 when the recommended number of LNs was harvested. The 5-year recurrence-free survival (RFS) rates using the Kaplan-Meier method were compared according to p/yp N stage and the LNR in each group. RESULTS: Among patients with the same p/ypN stage, the 5-year RFS rate differed according to the LNR. In addition, the 5-year RFS rate was significantly different between pN and LNR groups in patients with No PCRT. In PCRT group, however, only LNR was associated with prognosis. On multivariate analysis, both pN and LNR were significant independent prognostic factors for 5-year RFS in the No PCRT group. In the PCRT group, only LNR category was found to be associated with RFS (HR = 2.36, 95%CI: 1.31-3.84, and P = 0.001). CONCLUSION: The LNR is an important prognostic predictor of RFS in rectal cancer patients especially treated with PCRT. Current pN categories could not discriminate between prognostic groups of RFS after PCRT. PMID:25805934

    Background: Diabetic patients with endometrial cancer had more lymph node metastasis than non-diabetic patients with endometrial cancer. L1 cell adhesion molecule (L1CAM) could be possibly associated with lymph node metastasis in diabetic patients with endometrial cancer via epithelial-mesenchymal transition. We aimed to investigate the association between L1CAM expression and lymph node metastasis in diabetic patients with endometrial cancer. Methods: We conducted a matched case control study of 68 endometrial cancer patients who comprise each 34 diabetic and non-diabetic patients. L1CAM expression was evaluated by immunohistochemistry using fresh formalin-fixed paraffin-embedded tissue block of the patients. The association between L1CAM expression and pelvic lymph node metastasis was assessed according to the presence of diabetes. Results: Of the 68 patients, 13 (19.1%) were positive for L1CAM immunostaining. Positive rate of L1CAM expression in diabetic endometrial cancer patients was similar to that in non-diabetic endometrial cancer patients (14.7% vs. 23.5%, P = 0.355). Tumor recurred more frequently in patients with positive L1CAM expression than those with negative L1CAM expression (33.3% vs. 1.6%, P = 0.019). However, we failed to find any significant association between L1CAM expression and lymph node metastasis. Only for the diabetic patients (n = 34), patients with pelvic lymph node metastasis had more L1CAM expression than those without lymph node metastasis (50.0% vs. 3.6%, P = 0.035). Advanced stage was the only risk factor for recurrence that showed a significant association with L1CAM expression for the diabetic endometrial cancer patients (P = 0.006), as well as all the enrolled patients (P = 0.014). Conclusion: L1CAM expression is associated with pelvic lymph node metastasis and advanced stage in diabetic patients with endometrial cancer. PMID:25337593

    Aims To assess the clinical significance and risk factors of solitary lymph node metastasis (SLM) in gastric carcinoma and establish a more accurate method to evaluate the possibility of lymph node metastasis (LM). Methods A total of 385 patients with gastric carcinoma who underwent D2 lymphadenectomy at the Cancer Center of Sun Yat-Sen University were included in this research. Then we used a group of data from Sun Yat-sen University Gastrointestinal Hospital (SYSUGIH) to validate the accuracy of our developed method. The ?2 test, Kaplan–Meier analysis, log-rank test, COX model, and discriminate analysis were used to analyze the data with SPSS13.0. Results We found that the LM number and pathological T staging were independent prognostic risk factors. CEA grading, LN status by CT, and T staging by CT were independent risk factors for LM in gastric carcinoma. In addition, we developed the equation Y = -5.0 + X1 + 1.8X3 + 0.7X4 (X1 = CEA grading, X3 = LN status by CT, X4 = T staging by CT) to evaluate the situation of LM. The data from SYSUGIH shows this equation has a better accuracy compared with CT. Conclusions SLM is an independent risk factor in gastric cancer. And there was no survival difference between the skip metastasis group and the other SLM group (P = 0.659). It is inappropriate for the patient with SLM doing a standard D2 lymphadenectomy, due to the fact that LM rarely occurs in the splenic artery, splenic hilum. The risk factors for LM include CEA grading, LN status by CT, and T staging by CT. And we can use Y = -5.0 + X1 + 1.8X3 + 0.7X4 (X1, CEA grading, X3 = LN status by CT, X4 = T staging by CT, the critical value is 0.3) to estimate the possibility of LM, which has a better accuracy compared with CT.

    Background Autophagy has paradoxical and complex functions in cancer development, and autophagy-related genes (ATG) are key regulators in autophagy. Until now, more than 30 different ATG proteins have been identified in yeast, and their mammalian counterparts also have been reported. Although the roles of a few ATG proteins in cancer have been characterized, the role of ATG10 is almost completely unknown. Methodology/Principal Findings To investigate the clinicopathological role of ATG10 in colorectal cancer, we analyzed ATG10 expression in colorectal cancer tissues and cell lines. Protein expression analysis showed that ATG10 is highly increased in colorectal cancer (tissue - 18/37 cases, 48%; cell line –8/12 cell lines, 66%). Immunohistochemical analysis with clinicopathological features indicated a strong association of the up-regulation of ATG10 with tumor lymph node metastasis (p?=?0.005) and invasion (p<0.001). Moreover, both 5-year disease free survival and overall survival rates of patients bearing tumors that did not express ATG10 were significantly higher than those of patients bearing ATG10-expressing tumors (p?=?0.012). Conclusion/Significance Increased expression of ATG10 in colorectal cancer is associated with lymphovascular invasion and lymph node metastasis indicating that ATG10 may be a potential prognostic maker in colorectal cancer.

    In the sentinel node era, axillary dissection (ALND) for breast cancer (BC) is required much less frequently than in the past. However, complications, such as prolonged drainage output and seroma formation, are still observed. Harmonic dissection devices (HDDs) are widely used in laparoscopic and minimally invasive surgery to reduce collateral damage during tissue dissection, but its usefulness in breast surgery is unclear. The aim of this study was to evaluate the efficacy of HDDs compared to that of conventional dissection in performing ALND. One hundred thirty-nine women (median age 61 years, range 34-71 years) with confirmed pT1-2 primary infiltrating ductal BC undergoing curative surgery were enrolled in the study. The population was prospectively randomized between two age- and stage-matched arms: group A (cases)-68 (48.9 %) patients (HDD technique), versus group B (controls)-71 (51.1 %) patients (conventional technique). In group B, skin flaps were obtained using a scalpel, scissors, and electrocautery which was never used for ALND. In group A, for each operation time, the HDDs were used exclusively. The mean operative time, intraoperative blood loss, and drainage output were (A vs. B) 95 ± 22 versus 109 ± 25 min, 56 ± 12 versus 86 ± 15 mL, and 412 ± 83 versus 456 ± 69 mL, respectively (p < 0.01). Twenty-nine (20.9 %) patients developed an axillary seroma: 9 (13.2 %) and 20 (28.2 %) for groups A and B, respectively (p = 0.030). Our study confirms that in patients with BC requiring ALND the use of HDDs is more time efficient than conventional surgery, and reduces intraoperative bleeding, the amount of drainage, and the risk of seroma formation. These results may lead to several short- and long-term advantages. Thus, a careful evaluation of the cost-benefits of nontraditional tools, such as HDDs, should be performed in all patients undergoing modified radical or partial mastectomy and ALND for BC.

    A staging programme for detection of lymph node involvement before radical cystectomy has been carried out in 22 patients. The programme includes: intravenous pyelography, chest X-ray, abdominal sonography, bone scan, CT and MRI. Also an immunoscintigraphic examination using monoclonal anti-CEA antibody (TUMAK BW 421/26) was done in every patient. Preoperative lymph node staging using CT, MRI and immunoscintigraphy was compared with post-operative histological staging: a total of 5 patients were found to have lymph node involvement. In none of them had lymph node involvement been predicted on the basis of CT, MRI or immunoscintigraphy. PMID:8447046

    AIM: To evaluate the biopathologic features and clinical significance of nodal micrometastasis (MI) in early gastric cancer (EGC). METHODS: Among 1022 EGC patients who underwent gastrectomy with lymphadenectomy of D1 + ? or more from March 2001 to December 2005 at the Korean National Cancer Center, available nodal metastasis was found in 90 pT1N1 patients. Nodal metastasis was confirmed by immunohistochemistry (IHC) with cytokeratin and patients were classified into MI and macrometastasis (MA) groups based on the main tumor burden according to the 6th International Union Against Cancer/American Joint Committee on Cancer staging system; the main tumor burden with a diameter of greater than 0.2 mm but no greater than 2 mm as MI, and greater than 2 mm as MA of the representative metastatic node. Proliferative and apoptotic activities of the primary tumor and the nodal metastasis were measured by IHC with Ki-67 and terminal deoxynucleotidyl transferase dUTP nick end labeling, respectively. Biopathologic and clinical features of the patients were analyzed and compared between MI and MA groups. Patients with recurrence were compared with those without recurrence to identify risk factors for recurrence. RESULTS: Thirty-seven patients showed MI and the other 53 patients revealed MA in the lymph node; the incidence of patients with MI and MA was 41.1% and 58.9%. The main tumor burden was 0.9 and 4.6 mm in the representative metastatic node, respectively. Japanese N2 stations were more frequently involved in MA group (20.9%) than in MI group (10.3%) but the difference was not statistically different (P = 0.338). Proliferative and apoptotic activities of MI were decreased than those of MA (26.7% vs 40.5%, P = 0.004 and 1.0% vs 3.0%, P < 0.001, respectively). However, nodal MI in the current study showed a relatively high proliferative activity and an equivalent apoptotic activity compared to other cancers in the previously published studies. Recurrence was observed in 6 patients during the mean follow up period of 87.6 ± 26.2 mo. The recurrence was significantly associated with the presence of MA (P = 0.041) and lymphovascular invasion of the primary tumor (P = 0.032). CONCLUSION: Lymphadenectomy of D1 + ? or more might be necessary in patients with MI in sentinel node to prevent recurrence by clearing MI involving Japanese N2 station. PMID:25593497

    The aim was to explore the utility for staging and prognostic impact of carcinoembryonic antigen (CEA), cytokeratin 20 (CK20), guanylyl cyclase C (GCC), CUB (complement protein subcomponents C1r/C1s, urchin embryonic growth factor, and bone morphogenic protein 1) containing domain protein 1 (CDCP1) and mucin 2 (MUC2) mRNA levels in mesenteric lymph nodes of colorectal cancer (CRC) patients. Lymph nodes were collected at surgery and bisected; one half was subjected to biomarker mRNA analysis using real-time quantitative RT-PCR and the other half to routine histopathology. Lymph nodes from 174 CRC patients and 24 controls were analyzed. The median follow-up time was 59 (range 17-131) months. Cut-off levels were defined by analyzing quintiles by Cox regression model. CEA mRNA showed the best discriminating power between patients with recurrence in CRC after surgery and patients who were apparently disease-free (p = 0.015). The risk of recurrence for the CEA(+) patients was 4.6 times greater than for the CEA(-) patients (p < 0.0001). The other biomarkers gave lower hazard ratios. Cumulative survival analysis demonstrated that the average survival time was 99 months for CEA(-) patients compared to 39 months for CEA(+) patients, a difference of 60 months (p < 0.0001). Six to nine percent of the Stage I and Stage II patients [H&E(-)] had CEA(+), CK20(+), GCC(+) and/or MUC2(+) lymph nodes. Two of these patients died from recurrent CRC. Low lymph node MUC2/CEA mRNA ratio identified patients with high risk for recurrence (p = 0.011). Thus, quantitative reverse transcriptase-polymerase chain reaction of CEA mRNA is a sensitive method to identify tumor cells in lymph nodes of CRC patients and, in combination with MUC2 mRNA, allows improved prediction of clinical outcome.

    Aim: The present study was conducted to detect the musculature variations during axillary dissection for breast cancer surgery. Methods: The anatomy of axilla regarding muscular variations was studied in 50 patients who had an axillary dissection for the staging and treatment of invasive primary breast cancer over one year. Results: In a period of one year, two patients (4%) with axillary arch and one patient (2%) with absent pectoralis major and minor muscles among fifty patients undergoing axillary surgery for breast cancer were identified. Conclusions: Axillary arch when present should always be identified and formally divided to allow adequate exposure of axillary contents, in order to achieve a complete lymphatic dissection. Complete absence of pectoralis major and minor muscles precludes the insertion of breast implants and worsens the prognosis of breast cancer.

    Purpose: To evaluate the efficacy and toxicity of concurrent chemoradiotherapy (CCRT) with curative intent in patients with stage IVB cervical cancer initially presenting with paraortic and left supraclavicular lymph node metastases. Methods and Materials: The medical records of 25 patients with both paraortic and left supraclavicular lymph nodal metastases (group I) were reviewed and compared with those of 101 women with paraortic lymph node metastases alone (group II). Group I received a mean 59.4 Gy to the paraortic and left supraclavicular areas and 50.4 Gy to the pelvis, followed by 30 Gy of high-dose-rate brachytherapy in 6 fractions. Group II received the same dose to the paraortic area and pelvis followed by intracavitary brachytherapy. All patients received platinum-based chemotherapy simultaneously. Results: Of the 25 patients in group I, 16 (64%) experienced acute grade 3-4 hematologic toxicities, and 1 had a late grade 3 genitourinary toxicity. Complete responses, including the primary mass and pelvic, paraortic, and left supraclavicular lymph nodes, were observed in 13 patients (52%). At a median follow-up of 32 months for surviving patients, 3 experienced in-field failure, 6 showed distant failure, and 9 showed both. The 3-year overall and disease-free survival rates were 49% and 33%, respectively. In comparison, of the 101 patients in group II, 16 showed in-field failure, 14 experienced distant failure, and 11 showed both. The 3-year overall and disease-free survival rates were 69% and 57%, respectively. Conclusions: Curative CCRT is feasible in patients with stage IVB cervical cancer presenting with paraortic and left supraclavicular lymph nodal metastases, with acceptable late toxicity and high response rates, despite high rates of acute hematologic toxicity.

    Highlights: Black-Right-Pointing-Pointer ActRIB signaling induces Snail and S100A4 expressions in prostate cancer cells. Black-Right-Pointing-Pointer The prostate cancer cell lines expressing an active form of ActRIB were established. Black-Right-Pointing-Pointer ActRIB signaling promotes EMT and lymph node metastasis in xenograft model. -- Abstract: Activin, a member of the transforming growth factor-{beta} family, has been known to be a growth and differentiating factor. Despite its pluripotent effects, the roles of activin signaling in prostate cancer pathogenesis are still unclear. In this study, we established several cell lines that express a constitutive active form of activin type IB receptor (ActRIBCA) in human prostate cancer cells, ALVA41 (ALVA-ActRIBCA). There was no apparent change in the proliferation of ALVA-ActRIBCA cells in vitro; however, their migratory ability was significantly enhanced. In a xenograft model, histological analysis revealed that the expression of Snail, a cell-adhesion-suppressing transcription factor, was dramatically increased in ALVA-ActRIBCA tumors, indicating epithelial mesenchymal transition (EMT). Finally, mice bearing ALVA-ActRIBCA cells developed multiple lymph node metastases. In this study, we demonstrated that ActRIBCA signaling can promote cell migration in prostate cancer cells via a network of signaling molecules that work together to trigger the process of EMT, and thereby aid in the aggressiveness and progression of prostate cancers.

    Cervical cancer is the third most common cancer in women worldwide. In the present study, global microRNA profiling for 79 cervical cancer patient samples led to the identification of miR-218 down-regulation in cervical cancer tissues compared to normal cervical tissues. Lower miR-218 expression was associated significantly with worse overall survival (OS), disease-free survival (DFS), and pelvic/aortic lymph node recurrence. In vitro, miR-218 over-expression decreased clonogenicity, migration, and invasion. Survivin (BIRC5) was subsequently identified as an important cervical cancer target of miR-218 using in silico prediction, mRNA profiling, and quantitative real-time PCR (qRT-PCR). Concordant with miR-218 over-expression, survivin knockdown by siRNA decreased clonogenicity, migration, and invasion. YM155, a small molecule survivin inhibitor, significantly suppressed tumor growth and lymph node metastasis in vivo. Our findings demonstrate that the miR-218~survivin axis inhibits cervical cancer progression by regulating clonogenicity, migration, and invasion, and suggest that the inhibition of survivin could be a potential therapeutic strategy to improve outcome in this disease.

    Methodology. Seventeen patients with prostate-specific antigen (PSA) rise following local treatment for prostate cancer with curative intent underwent open or minimally invasive salvage pelvic lymph node dissection (SLND) for oligometastatic disease (<4 synchronous metastases) or as staging prior to salvage radiotherapy. Biochemical recurrence after complete biochemical response (cBR) was defined as 2 consecutive PSA increases >0,2?ng/mL; and after incomplete biochemical response as 2 consecutive PSA rises. Newly found metastasis on imaging defined clinical progression (CP). Palliative androgen deprivation therapy (ADT) was initiated if >3 metastases were detected or if patients became symptomatic. Kaplan-Meier statistics were applied. Results. Clavien-Dindo grade 1, 2, 3a, and 3b complications were seen in 6, 1, 1, and 2 patients, respectively. Median follow-up time was 22 months. Among 13 patients treated for oligometastatic disease, 8 (67%) had a PSA decline, with 3 patients showing cBR. Median PSA progression-free survival (FS) was 4.1 months and median CP-FS 7 months. Three patients started ADT, resulting in a 2-year ADT-FS rate of 79.5%. Conclusion. SLND is feasible, but postoperative complication rate seems higher than that for primary LND. Biochemical and clinical response duration is limited, but as part of an oligometastatic treatment regime it can defer palliative ADT. PMID:25695051

    AIM: To investigate the influence of tumor grade on sentinel lymph node (SLN) status in patients with gastric cancer (GC). METHODS: We retrospectively studied 71 patients with GC who underwent SLN mapping during gastric surgery to evaluate the relationship between SLN status and tumor grade. RESULTS: Poorly differentiated tumors were detected in 50/71 patients, while the other 21 patients had moderately differentiated tumors. SLNs were identified in 58/71 patients (82%). In 41 of the 58 patients that were found to have stained nodes (70.7%), the tumor was of the poorly differentiated type (group?I), while in the remaining patients with stained nodes 17/58 (29.3%), the tumor was of the moderately differentiated type (group II). Positive SLNs were found in 22/41 patients in group I (53.7%) and in 7/17 patients in group II (41.2%) (P = 0.325). The rate of positivity for the SLNs in the two groups (53.7% vs 41.2%) was not statistically significant (P = 0.514). CONCLUSION: Most of our patients were found to have poorly differentiated adenocarcinoma of the stomach and there was no correlation between tumor grade and SLN involvement. PMID:24627734

    Purpose: To compare the nodal risk formula (NRF) as a predictor for lymph node (LN) metastasis in patients with prostate cancer with magnetic resonance lymphography (MRL) using Ultrasmall Super-Paramagnetic particles of Iron Oxide (USPIO) and with histology as gold standard. Methods and Materials: Logistic regression analysis was performed with the results of histopathological evaluation of the LN as dependent variable and the nodal risk according to the NRF and the result of MRL as independent input variables. Receiver operating characteristic (ROC) analysis was performed to assess the performance of the models. Results: The analysis included 375 patients. In the single-predictor regression models, the NRF and MRL results were both significantly (p <0.001) predictive of the presence of LN metastasis. In the models with both predictors included, NRF was nonsignificant (p = 0.126), but MRL remained significant (p <0.001). For NRF, sensitivity was 0.79 and specificity was 0.38; for MRL, sensitivity was 0.82 and specificity was 0.93. After a negative MRL result, the probability of LN metastasis is 4% regardless of the NRF result. After a positive MRL, the probability of having LN metastasis is 68%. Conclusions: MRL is a better predictor of the presence of LN metastasis than NRF. Using only the NRF can lead to a significant overtreatment on the pelvic LN by radiation therapy. When the MRL result is available, the NRF is no longer of added value.

    Background. Treatment of patients with a biochemical recurrence (BCR) of prostate cancer (PCa) is generally difficult and without valid treatment options. Since 2004 we have been developing therapeutic possibilities for these patients. Methods. We retrospectively analyzed a cohort of 41 patients with a BCR of PCa and a mean followup of 40.3 ± 20.8 months. Group 1 (n = 10): salvage radical prostatectomy (sRP) with SePLND (salvage extended pelvic lymph nodes dissection) (initial treatment: combined brachytherapy). Group 2 (n = 22): SePLND (initial treatment: radical prostatectomy (RP)). Group 3 (n = 9): SePLND (initial treatment: RP and adjuvant radiation therapy (RT)). We observed PSA, PSA-velocity, localization of LNs and LNs+, BCR-free period, and BR (biochemical response). Results. Group 1: 60% with BCR-freedom (mean 27.2 months). Group 2: 63.6% with BCR-freedom (mean 17.5 months). Group 3: 33.3% with BCR-freedom (mean 17.6 months). In total, BCR-freedom was observed in 23 of 41 patients (56.1%) after salvage surgery. 75.6% of all patients showed a BR. 765?LNs were removed and 14.8% of these were LN+. Conclusions. The BCR-free period and BR are comparable in all three groups. Sensibility to ADT can be reestablished and prolonged as a result of SePLND. Multicenter studies are needed for a reliable output.

    Objective The 7th edition of AJCC staging manual implicitly states that only T1 and T2 lesions that lack regional lymph node metastasis but have tumor deposit(s) will be classified in addition as N1c, though it is not consistent in that pN1c is also an option for pT3/T4a tumors in the staging table. Nevertheless, in this TNM classification, how to classify tumor deposits (TDs) in colorectal cancer patients with lymph node metastasis (LNM) and TDs simultaneously is still not clear. The aim of this study is to investigate the possibility of counting TDs as metastatic lymph nodes in TNM classification and to indentify its prognostic value for colorectal cancer patients. Methods and Results In this retrospective study, 513 cases of colorectal cancer with LNM were reviewed. We proposed a novel pN (npN) category in which TDs were counted as metastatic lymph nodes in the TNM classification. Cancer-specific survival according to the npN or pN category was analyzed using Kaplan-Meier survival curves. Univariate and multivariate analyses were performed to indentify significant prognostic factors. Harrell's C statistic was used to test the predictive capacity of the prognostic models. The results revealed that the TD was a significant prognostic factor in colorectal cancer. Univariate and multivariate analyses uniformly indicated that the npN category was significantly correlated with prognosis. The results of Harrell's C statistical analysis demonstrated that the npN category exhibited a superior predictive capacity compared to the pN category of the 7th edition TNM classification. Moreover, we also found no significant prognostic differences in patients with or without TD in the same npN categories. Conclusions The counting of TDs as metastatic lymph nodes in the TNM classification system is potentially superior to the classification in the 7th edition of the TNM staging system to assess prognosis and survival for colorectal cancer patients.

    The Royal College of Pathologists (RCPath) and College of American Pathologists recommend that at least 12 lymph nodes should be harvested for adequate staging of colorectal carcinoma. Just one nodal tumour deposit upstages the malignancy from pN0 to pN1. This is critically important as node-positive patients (pN1) are considered for adjuvant chemotherapy whereas node-negative patients (pN0) may not be. It is not always easy to harvest the required number, especially in patients with rectal carcinoma who may have received neoadjuvant therapy-an increasingly common treatment. The use of neoadjuvant therapy is known to further decrease the number and size of identifiable lymph nodes within specimens, meaning that the lymph node harvest often fails to reach RCPath guidelines. Lymph node revealing solutions consisting of either single chemicals such as alcohol or acetone or compounds have been investigated to help improve the lymph node harvest in difficult specimens, for example, those received following neoadjuvant therapy. Published research evidence reviewed here suggests that lymph node revealing solutions significantly improve lymph node harvesting, and that glacial acetic acid, ethanol, water and formalin is advantageous in comparison with other revealing solutions in that it is safe, cheap, easy to use and relatively quick. However, the quantity of good evidence is limited and the clinical implications of improving lymph node harvesting require further research. PMID:24493650

    Accurate preoperative staging and restaging of mediastinal lymph nodes in patients with potentially resectable non-small cell lung cancer (NSCLC) is of paramount importance. In 2007, the European Society of Thoracic Surgeons (ESTS) published an algorithm on preoperative mediastinal staging integrating imaging, endoscopic and surgical techniques. Over the last years more evidence of the different mediastinal staging technique has become available. Therefore, a revision of the ESTS guidelines was needed. In case of CT-enlarged or PET-positive mediastinal lymph nodes, tissue confirmation is indicated. Endosonography (EBUS/EUS) with fine needle aspiration is the first choice (when available) since it is minimally invasive and has a high sensitivity to rule in mediastinal nodal disease. If negative, surgical staging with nodal dissection or biopsy is indicated. Video-assisted mediastinoscopy is preferred over mediastinoscopy. The combined use of endoscopic staging and surgical staging results in the highest accuracy. When there are no enlarged lymph nodes on CT and when there is no uptake in lymph nodes on PET or PET-CT, direct surgical resection with systematic nodal dissection is indicated for tumors ?3 cm located in the outer third of the lung. In central tumors or N1 nodes, preoperative mediastinal staging is indicated. The choice between endoscopic staging with EBUS/EUS and fine needle aspiration or video-assisted mediastinoscopy depends on local expertise to adhere to minimal requirements for staging. For tumors larger than 3 cm, preoperative mediastinal staging is advised, mainly in adenocarcinoma with high SUV uptake.

    Stem cell marker nestin has been reported to be activated in various neoplasms, and its expression is correlated with poor prognosis. However, nestin expression in non-small cell lung cancer still remains unclear. The present study aimed to investigate nestin expression in 52 tissue samples of non-small cell lung cancer by immunohistochemical staining and explore its correlation with some clinicopathologic characteristics. The associations of nestin with lymphatic vessel density, microvessel density, vascular endothelial growth factor, vascular endothelial growth factor-C, and cyclooxygenase-2 (COX-2) were further observed to determine the linkage between nestin and lymphangiogenesis. The results showed that nestin expressed in tumor cells of 45 samples. High nestin expression correlated significantly with poor differentiation (P = .007), adenocarcinoma (P = .000), N2 lymph node metastasis (P = .006), high microvessel density (P = .033), and lymphatic vessel density (P = .020). Multivariate analysis of N1 and N2 lymph node metastasis revealed a 1.086-fold increase in hazard ratio of N2 lymph node involvement (P = .011) in patients with high nestin expression in primary tumor. More important, multivariate analysis showed a significant correlation of lymphatic vessel density with nestin and vascular endothelial growth factor-C expression (P = .039 and P = .045), independent of vascular endothelial growth factor, COX-2, and other clinicopathologic characteristics. The results demonstrated that nestin expressed in most tumor cells of non-small cell lung cancer tissue and had a direct linkage to lymph node metastasis and tumor-induced lymphangiogenesis, independent of COX-2 signal pathway.

    Colorectal cancer (CRC) is the fourth most common non-cutaneous malignancy in the United States and the second most frequent cause of cancer-related death. One of the most important determinants of CRC survival is lymph node metastasis. To determine whether molecular markers might be prognostic for lymph node metastases, we measured by quantitative real-time RT–PCR the expression levels of 15 cancer-associated genes in formalin-fixed paraffin-embedded primary tissues derived from stage I–IV CRC patients with (n=20) and without (n=18) nodal metastases. Using the mean of the 15 genes as an internal reference control, we observed that low expression of ?2microglobulin (B2M) was a strong prognostic indicator of lymph node metastases (area under the curve (AUC)=0.85; 95% confidence interval (CI)=0.69–0.94). We also observed that the expression ratio of B2M/Spint2 had the highest prognostic accuracy (AUC=0.87; 95% CI=0.71–0.96) of all potential two-gene combinations. Expression values of Spint2 correlated with the mean of the entire gene set at an R2 value of 0.97, providing evidence that Spint2 serves not as an independent prognostic gene, but rather as a reliable reference control gene. These studies are the first to demonstrate a prognostic role of B2M at the mRNA level and suggest that low B2M expression levels might be useful for identifying patients with lymph node metastasis and/or poor survival.

    A purpose of this study was to establish a novel molecular diagnostic model and provide new insight into the intraoperative evaluation of the sentinel lymph node (SLN) metastasis in breast cancer. A total of 124 breast cancer patients who met the criteria of sentinel lymph node biopsy (SLNB) and underwent intraoperative biopsy were consecutively enrolled in this study. After the SLNs obtained from each patient were labeled, MOC-31 monoclonal antibody-mediated immunomagnetic separation (IMS) and flow cytometry were used to determine the expressions of breast cancer metastasis-related markers, including Mucin 1 (MUC1), CD44v6, and HER2. Alternatively, conventional intraoperative hematoxylin and eosin (HE) staining and cytokeratin immunohistochemistry (CK-IHC) were performed to detect potential SLN metastasis. The sensitivity, specificity, and false-negative rate of the three intraoperative diagnostic methods were compared and analyzed. A total of 55 positive-SLNs were found in 38 breast cancer patients using IMS, yielding a sensitivity of 86.4% (38/44), specificity of 94.7% (36/38), accuracy of 93.5% (116/124), false-positive rate of 2.5% (2/80), false-negative rate of 13.6% (6/44), positive predictive value of 95.5% (42/44), and negative predictive value of 93.0% (80/86). Patients with high expressions of CD44v6, MUC1, and HER2 in SLNs tended to have higher number of positive lymph nodes, among which the MUC1 and HER2 showed significant differences (P<0.05). Therefore, compared with conventional HE staining and CK-IHC, IMS technology has remarkably higher sensitivity and specificity and relative lower false-negative rate, thus making it an effective and feasible intraoperative detection method of SLN for breast cancer diagnosis to some extent.

    Introduction The overall survival rate is good for lymph-node-negative breast cancer patients, but they still suffer from serious over- and some undertreatments. Prognostic and predictive gene signatures for node-negative breast cancer have a high number of genes related to proliferation. The prognostic value of gene sets from commercial gene-expression assays were compared with proliferation markers. Methods Illumina WG6 mRNA microarray analysis was used to examine 94 fresh-frozen tumour samples from node-negative breast cancer patients. The patients were divided into low- and high-risk groups for distant metastasis based on the MammaPrint-related genes, and into low-, intermediate- and high-risk groups based on the recurrence score algorithm with genes included in Oncotype DX. These data were then compared to proliferation status, as measured by the mitotic activity index, the expressions of phosphohistone H3 (PPH3), and Ki67. Results Kaplan-Meier survival analysis for distant-metastasis-free survival revealed that patients with weak and strong PPH3 expressions had 14-year survival rates of 87% (n?=?45), and 65% (n?=?49, p?=?0.014), respectively. Analysis of the MammaPrint classification resulted in 14-year survival rates of 80% (n?=?45) and 71% (n?=?49, p?=?0.287) for patients with low and high risks of recurrence, respectively. The Oncotype DX categorization yielded 14-year survival rates of 83% (n?=?18), 79% (n?=?42) and 68% (n?=?34) for those in the low-, intermediate- and high-risk groups, respectively (p?=?0.52). Supervised hierarchical cluster analysis for distant-metastasis-free survival in the subgroup of patients with strong PPH3 expression revealed that the genes involved in Notch signalling and cell adhesion were expressed at higher levels in those patients with distant metastasis. Conclusion This pilot study indicates that proliferation has greater prognostic value than the expressions of either MammaPrint- or Oncotype-DX-related genes. Furthermore, in the subgroup of patients with high proliferation, Notch signalling pathway genes appear to be expressed at higher levels in patients who develop distant metastasis. PMID:24599057

  19. Design and development of a dedicated mammary and axillary region positron emission tomography system

    NASA Astrophysics Data System (ADS)

    Breast cancer is the second leading cause of cancer death in women. Currently, mammography and physical breast examination, both non-invasive techniques, provide the two most effective methods available for screening potential breast cancer patients. During the management of patients, however, several invasive techniques such as axillary lymph node dissection, core biopsies and lumpectomies, are utilized to determine the stage or malignancy of the disease with significant cost and morbidity associated with them. Positron Emission Tomography (PET), using [F-18] fluorodeoxyglucose (FDG) tracer is a sensitive and non-invasive imaging modality that may be a cost-effective alternative to certain invasive procedures. In this project we have developed a low cost, high performance, dedicated PET camera (maxPET) for mammary and axillary region imaging. The system consists of two 15x15 cm2 planar scintillation detector arrays composed of modular detectors operating in coincidence. The modular detectors are comprised of a 9x9 array of 3x3x20 mm3 lutetiurn oxyorthosilicate (LSO) detector elements, read out by a 5x5 array of position- sensitive photomultiplier tubes. The average measured intrinsic spatial resolution of a detector module is 2.26 mm with a sensitivity of up to 40% for a central point source. The measured coincidence timing resolution for two modules is 2.4 ns. The average energy resolution measured across the entire two detector plates is 21.6%. The coincidence timing resolution for the entire system is 8.1 ns. A line bar phantom was imaged and images were reconstructed using the focal plane tomography algorithm. A 4 mm projection image resolution was measured based on profiles taken through the line bar phantom images. The goal of the maxPET system will be to aid in breast cancer patient management by assisting in imaging women with dense, fibro-glandular breasts, detecting axillary lymph node metastases without surgery, monitoring chemotherapy effectiveness and assisting in visualization of recurrence and tumoral boundaries.

    AIM: To study how lymph node metastasis (LNM) risk is stratified in undifferentiated-type early gastric cancer (undiff-EGC) dependent on combinations of risk factors. METHODS: Five hundred and sixty-seven cases with undiff-EGC undergoing gastrectomy with lymphadenectomy were examined retrospectively. Using clinicopathological factors of patient age, location, size, an endoscopic macroscopic tumor form, ulceration, depth, histology, lymphatic involvement (LI) and venous involvement (VI), LNM risk was examined and stratified by conventional statistical analysis and data-mining analysis. RESULTS: LNM was positive in 44 of 567 cases (7.8%). Univariate analysis revealed > 2 cm, protrusion, submucosal (sm), mixed type, LI and VI as significant prognostic factors and > 2 cm and LI-positive were independent factors by multivariate analysis. In preoperatively evaluable factors excluding LVI, sm and > 2 cm were independent factors. According to the depth and size, cases were categorized into the low-risk group [m and ? 2 cm, 0% (LNM incidence)], the moderate-risk group (m and > 2 cm, 5.6%; and sm and ? 2 cm, 6.0%), and the high-risk group (sm and > 2 cm, 19.3%). On the other hand, LNM occurred in 1.4% in all LI-negative cases, greatly lower than 28.2% in all LI-positive cases, and LNM incidence was low in LI-negative cases even in the moderate- and high-risk groups. CONCLUSION: LNM-related factors in undiff-EGC were depth and size preoperatively while those were LI and size postoperatively. Among these factors, LI was the most significantly correlated factor.

    Purpose: To evaluate if automatic atlas-based lymph node segmentation (LNS) improves efficiency and decreases inter-observer variability while maintaining accuracy. Methods and Materials: Five physicians with head-and-neck IMRT experience used computed tomography (CT) data from 5 patients to create bilateral neck clinical target volumes covering specified nodal levels. A second contour set was automatically generated using a commercially available atlas. Physicians modified the automatic contours to make them acceptable for treatment planning. To assess contour variability, the Simultaneous Truth and Performance Level Estimation (STAPLE) algorithm was used to take collections of contours and calculate a probabilistic estimate of the 'true' segmentation. Differences between the manual, automatic, and automatic-modified (AM) contours were analyzed using multiple metrics. Results: Compared with the 'true' segmentation created from manual contours, the automatic contours had a high degree of accuracy, with sensitivity, Dice similarity coefficient, and mean/max surface disagreement values comparable to the average manual contour (86%, 76%, 3.3/17.4 mm automatic vs. 73%, 79%, 2.8/17 mm manual). The AM group was more consistent than the manual group for multiple metrics, most notably reducing the range of contour volume (106-430 mL manual vs. 176-347 mL AM) and percent false positivity (1-37% manual vs. 1-7% AM). Average contouring time savings with the automatic segmentation was 11.5 min per patient, a 35% reduction. Conclusions: Using the STAPLE algorithm to generate 'true' contours from multiple physician contours, we demonstrated that, in comparison with manual segmentation, atlas-based automatic LNS for head-and-neck cancer is accurate, efficient, and reduces interobserver variability.

    Harvesting lymph nodes (LNs) after gastrectomy is essential for accurate staging. This trial evaluated the efficiency and quality of a conventional method and a methylene blue–assisted method in a randomized manner. The key eligibility criteria were as follows: (i) histologically proven adenocarcinoma of the stomach; (ii) clinical stage I-III; (iii) R0 resection planned by gastrectomy with D1+ or D2 lymphadenectomy. The primary endpoint was the ratio of the pathologic number of harvested LNs per time (minutes) as an efficacy measure. The secondary endpoint was the number of harvested LNs, as a quality measure. Between August 2012 and December 2012, 60 patients were assigned to undergo treatment using the conventional method (n=29) and the methylene blue dye method (n=31). The baseline demographics were mostly well balanced between the 2 groups. The number of harvested LNs (mean±SD) was 33.6±11.9 in the conventional arm and 43.4±13.9 in the methylene blue arm (P=0.005). The ratio of the number of the harvested LNs per time was 1.12±0.46 LNs/min in the conventional arm and 1.49±0.59 LNs/min in the methylene blue arm (P=0.010). In the subgroup analyses, the quality and efficacy were both superior for the methylene blue dye method compared with the conventional method. The methylene blue technique is recommended for harvesting LNs during gastric cancer surgery on the basis of both the quality and efficacy. PMID:25356528

    Purpose To prospectively demonstrate the feasibility of using indocyanine green, a near-infrared (NIR) fluorophore at the minimum dose needed for noninvasive optical imaging of lymph nodes (LNs) in breast cancer patients undergoing sentinel lymph node mapping (SLNM). Materials and Methods Informed consent was obtained from 24 women (age range, 30–85 years) who received intradermal subcutaneous injections of 0.31–100 ?g indocyanine green in the breast in this IRB-approved, HIPAA-compliant, dose escalation study to find the minimum microdose for imaging. The breast, axilla, and sternum were illuminated with NIR light and the fluorescence generated in the tissue was collected with an NIR-sensitive intensified charged-coupled device. Lymphoscintigraphy was also performed. Resected LNs were evaluated for the presence of radioactivity, blue dye accumulation, and fluorescence. The associations between the resected LNs that were fluorescent and (a) the time elapsed between NIR fluorophore administration and resection and (b) the dosage of NIR fluorophores were tested with the Spearman rank and Pearson product moment correlation tests, respectively. Results Lymph imaging consistently failed with indocyanine green microdosages between 0.31 and 0.77 ?g. When indocyanine green dosages were 10 ?g or higher, lymph drainage pathways from the injection site to LNs were imaged in eight of nine women; lymph propulsion was observed in seven of those eight. When propulsion in the breast and axilla regions was present, the mean apparent velocities ranged from 0.08 to 0.32 cm/sec, the time elapsed between “packets” of propelled fluid varied from 14 to 92 seconds. In patients who received 10 ?g of indocyanine green or more, a weak negative correlation between the fluorescence status of resected LNs and the time between NIR fluorophore administration and LN resection was found. No statistical association was found between the fluorescence status of resected LNs and the dose of NIR fluorophore. Conclusion NIR fluorescence imaging of lymph function and LNs is feasible in humans at microdoses that would be needed for future molecular imaging of cancer-positive LNs. PMID:18223125

    Cancer of the papilla or the ampulla of Vater appears, from a clinical point of view, to be an intraduodenal or ampullary cancer. An adenoma-dysplasia-carcinoma sequence has been established. In 20%-40% of the patients with an adenoma of the papilla, a cancerous lesion in the adenoma is additionally observed. Oncological resection using a Kausch-Whipple technique or a pylorus-preserving partial pancreatico-duodenectomy (PPPD) offers a 5-year survival probability of between 45% and 65%. The hospital mortality after oncological resection at experienced centers is below 5%. The most frequent treatment-related complication is pancreatic fistula, which occurs in around 20% of the patients. In about 10% of the patients with a pT1 cancer and in 25% to 67% with pT2 and pT3 cancer, lymph node involvement has been observed. Lymph nodes in front of and behind the head of the pancreas are the primary targets for cancer cell disseminations. In more than one-third of the patients, lymph nodes in the inter-aortocaval space and the lymph nodes around the superior mesenteric artery and the nodes in the pancreatic segment of the hepatoduodenal ligament are involved. Therefore, tissue dissection, including, selectively, the N2 lymph nodes, is an essential component of radical surgery for cancer of the papilla. A standard Kausch-Whipple resection or PPPD without a selective extended lymph node dissection, including the interaortocaval and superior mesenteric artery nodes, results in about 30% of the patients having an R2-resection, i.e., with cancer left behind. The long-term survival is determined by the tumor biological factors: (1) absence of lymph node involvement and (2) absence of infiltration into the pancreas. The surgeon's contribution to the cure of cancer of the papilla is to perform an R0-resection with low hospital mortality and low postoperative morbidity. Patients without lymph node involvement, and with absence of infiltration into the pancreas, no lymph vessel invasion, and tumor-negative margins have major benefits from oncological resection in regard to curability of the cancer.

    The recently developed method of ultrarapid immunohistochemistry (IHC) was applied to the intraoperative examination of sentinel lymph nodes (SLNs) in breast cancer patients. In a prospective study of 50 patients with invasive breast carcinomas, a total of 60 SLNs were studied. Among them, 33 SLNs from 30 patients were studied intraoperatively using a direct immunoperoxidase method with anticytokeratin antibody clone MNF116. This technique has a turnaround time of less than 20 minutes. Ultrarapid IHC revealed 15 positive SLNs compared to 14 positive SLNs using hematoxylin and eosin (H and E) frozen sections. The one SLN missed in H and E frozen sections presented with cytokeratin-positive isolated tumor cells in the lymph node sinus. After paraffin embedding, H and E-stained serial step sections of the SLN specimens detected another two patients with isolated tumor cells. We also examined the remaining axillary lymph nodes (ALNs) by H and E-stained serial step paraffin sections. From 17 of the 30 patients with positive SLNs, 6 patients also had metastatic involvement of the ALNs of level I or II. Thus ultrarapid IHC was a very sensitive and rapid technique for the intraoperative detection of metastatic involvement of SLNs in breast cancer patients. This technique may be a useful complementary tool for the intraoperative study of SLNs, particularly in tumors that are a diagnostic challenge, such as lobular carcinoma. PMID:12846860

    Purpose: To investigate the pattern of lymph node spread in prostate cancer patients with a biochemical recurrence after radical prostatectomy, eligible for salvage radiotherapy; and to determine whether the clinical target volume (CTV) for elective pelvic irradiation in the primary setting can be applied in the salvage setting for patients with (a high risk of) lymph node metastases. Methods and Materials: The charts of 47 prostate cancer patients with PSA recurrence after prostatectomy who had positive lymph nodes on magnetic resonance lymphography (MRL) were reviewed. Positive lymph nodes were assigned to a lymph node region according to the guidelines of the Radiation Therapy Oncology Group (RTOG) for delineation of the CTV for pelvic irradiation (RTOG-CTV). We defined four lymph node regions for positive nodes outside this RTOG-CTV: the para-aortal, proximal common iliac, pararectal, and paravesical regions. They were referred to as aberrant lymph node regions. For each patient, clinical and pathologic features were recorded, and their association with aberrant lymph drainage was investigated. The distribution of positive lymph nodes was analyzed separately for patients with a prostate-specific antigen (PSA) <1.0 ng/mL. Results: MRL detected positive aberrant lymph nodes in 37 patients (79%). In 20 patients (43%) a positive lymph node was found in the pararectal region. Higher PSA at the time of MRL was associated with the presence of positive lymph nodes in the para-aortic region (2.49 vs. 0.82 ng/mL; p = 0.007) and in the proximal common iliac region (1.95 vs. 0.59 ng/mL; p = 0.009). There were 18 patients with a PSA <1.0 ng/mL. Ten of these patients (61%) had at least one aberrant positive lymph node. Conclusion: Seventy-nine percent of the PSA-recurrent patients had at least one aberrant positive lymph node. Application of the standard RTOG-CTV for pelvic irradiation in the salvage setting therefore seems to be inappropriate.

    Lymph node metastasis from gallbladder cancer is often found in the pericholedochal area; however, these regional lymph nodes are not typically accompanied by arteries. We hypothesized that the artery accompanying pericholedochal lymph nodes was either the regressed embryonic right hepatic artery (eRHA) or an aberrant right hepatic artery (aRHA) remaining without regression. This study aimed to determine the artery supplying pericholedochal lymph nodes. We obtained serial tissue sections of resected specimens from 10 patients who underwent pancreaticoduodenectomy with combined resection of the superior mesenteric artery and vein and investigated the association between the distribution of enlarged lymph nodes and the course of blood vessels in each section. In 2 cases with aRHA, enlarged lymph nodes were distributed in the posterosuperior area, pancreaticoduodenal region and retroportal area along this artery. By contrast, no blood vessels accompanied enlarged lymph nodes in 8 patients exhibiting a normal hepatic artery branching pattern, although these nodes exhibited a distribution pattern similar to that of patients with the aRHA. Thus, the artery supplying pericholedochal lymph nodes appears to be either the regressed eRHA or an aRHA persisting without regression. PMID:25279182

    Purpose: Whole-pelvis (WP) concurrent chemoradiation (CCRT) is the standard bladder preserving option for patients with invasive bladder cancer. The standard practice is to treat elective pelvic lymph nodes, so our aim was to evaluate whether bladder-only (BO) CCRT leads to results similar to those obtained by standard WP-CCRT. Methods and Materials: Patient eligibility included histopathologically proven muscle-invasive bladder cancer, lymph nodes negative (T2-T4, N-) by radiology, and maximal transurethral resection of bladder tumor with normal hematologic, renal, and liver functions. Between March 2005 and May 2006, 230 patients were accrued. Patients were randomly assigned to WP-CCRT (120 patients) and BO-CCRT (110 patients). Data regarding the toxicity profile, compliance, initial complete response rates at 3 months, and occurrence of locoregional or distant failure were recorded. Results: With a median follow-up time of 5 years (range, 3-6), WP-CCRT was associated with a 5-year disease-free survival of 47.1% compared with 46.9% in patients treated with BO-CCRT (p = 0.5). The bladder preservation rates were 58.9% and 57.1% in WP-CCRT and BO-CCRT, respectively (p = 0.8), and the 5-year overall survival rates were 52.9% for WP-CCRT and 51% for BO-CCRT (p = 0.8). Conclusion: BO-CCRT showed similar rates of bladder preservation, disease-free survival, and overall survival rates as those of WP-CCRT. Smaller field sizes including bladder with 2-cm margins can be used as bladder preservation protocol for patients with muscle-invasive lymph node-negative bladder cancer to minimize the side effects of CCRT.

    Cancer-associated fibroblasts (CAF) influence tumor development at primary as well as in metastatic sites, but there have been no direct comparisons of the transcriptional profiles of stromal cells from different tumor sites. In this study, we used customized cDNA microarrays to compare the gene expression profile of stromal cells from primary tumor (CAF, n = 4), lymph node metastasis (N+, n = 3) and bone marrow (BM, n = 4) obtained from breast cancer patients. Biological validation was done in another 16 samples by RT-qPCR. Differences between CAF vs N+, CAF vs BM and N+ vs BM were represented by 20, 235 and 245 genes, respectively (SAM test, FDR < 0.01). Functional analysis revealed that genes related to development and morphogenesis were overrepresented. In a biological validation set, NOTCH2 was confirmed to be more expressed in N+ (vs CAF) and ADCY2, HECTD1, HNMT, LOX, MACF1, SLC1A3 and USP16 more expressed in BM (vs CAF). Only small differences were observed in the transcriptional profiles of fibroblasts from the primary tumor and lymph node of breast cancer patients, whereas greater differences were observed between bone marrow stromal cells and the other two sites. These differences may reflect the activities of distinct differentiation programs. PMID:25249769

    Purpose: To determine the impact of preoperative radiotherapy (RT) on the accuracy of lymph node staging (LNS). Preoperative RT is a well-established component of rectal cancer treatment but its impact on LNS is unknown. Methods and materials: The Surveillance, Epidemiology and End Results (SEER) registry, representing 14% of the U.S. population, was used to assess the impact of preoperative RT on LNS. Our study population consisted of adults with rectal cancer between 1998 and 2000 who underwent radical resection. Results: In our 3-year study period, 5647 patients met the selection criteria and 1034 (19.5%) underwent preoperative RT. The preoperative RT group was younger (average age, 61 years) than those who did not undergo preoperative RT (average age, 69 years) and more likely to be male (22% of men vs. 16% of women). On average, fewer nodes were examined in patients who underwent preoperative RT (7 nodes) vs. those who did not (10 nodes); this difference was statistically significant, controlling for potential confounders (p {<=} 0.0001). In 16% of the preoperative RT patients (vs. 7.5% without), no nodes were identified (p {<=} 0.0001). If one used a minimum of 12 nodes as the standard, only 20% of patients who underwent preoperative RT underwent adequate LNS. Conclusion: Lymph node staging in patients who undergo preoperative RT must be interpreted with caution. Studies are needed to evaluate the clinical relevance of node number and pathologic staging after preoperative RT for rectal cancer.

    Distant metastasis of head and neck squamous cell carcinoma (SCC) to the infraclavicular lymph nodes-with the exception of the upper mediastinal lymph nodes-is rare. We report the case of a 44-year-old man who was treated with surgery and radiotherapy for SCC of the floor of the mouth. During regular follow-up 6 months after the cessation of radiotherapy, F18-fluorodeoxyglucose positron-emission tomography/computed tomography (FDG-PET/CT) detected a hypermetabolic lesion in the left lobe of the liver that was diagnosed as a metastasis of the head and neck SCC; no locoregional recurrence was found. The metastasis was surgically removed and more radiotherapy was administered, but the SCC recurred at the same site and the patient died of disseminated disease 12 months after the appearance of the first metastasis. To the best of our knowledge, this is the first reported case of a solitary peritoneal lymph node metastasis from an SCC of the floor of the mouth. We believe that regular FDG-PET/CT follow-up scans are useful for the detection of unusual distant metastases of head and neck cancers. PMID:25531851

    Purpose To evaluate the use of dual-energy spectral computed tomographic (CT) quantitative parameters compared with the use of conventional CT imaging features for preoperative diagnosis of metastasis to the cervical lymph nodes in patients with papillary thyroid cancer. Materials and Methods This study was approved by the ethics committee and all patients provided written informed consent. Analyses of quantitative gemstone spectral imaging data and qualitative conventional CT imaging features were independently performed by different groups of radiologists. Excised lymph nodes were located and labeled during surgery according to location on preoperative CT images and were evaluated histopathologically. Single and combined parameters were fitted to simple and multiple logistic regression models, respectively, by means of the generalized estimating equations method. Sensitivity and specificity analyses were performed by using receiver operating characteristic curves and were compared with data from the qualitative analysis. Results The slope of the spectral Hounsfield unit curve ( ?HU slope of the spectral Hounsfield unit curve ), normalized iodine concentration, and normalized effective atomic number measured during both arterial and venous phases were significantly higher in metastatic than in benign lymph nodes. The best single parameter for detection of metastatic lymph nodes was venous phase ?HU, with sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of 62.0%, 91.1%, 80.6%, 79.7%, and 81.0%, respectively. The best combination of parameters was venous phase ?HU slope of the spectral Hounsfield unit curve and arterial phase normalized iodine concentration, with values of 73.0%, 88.4%, 82.9%, 78.0%, and 85.3%, respectively. Compared with qualitative analysis, the venous phase ?HU slope of the spectral Hounsfield unit curve showed higher specificity (91.1% vs 83.0%, P < .001) and similar sensitivity (62.0% vs 61.9%, P > .99), and the combined venous phase ?HU slope of the spectral Hounsfield unit curve and arterial phase normalized iodine concentration showed higher sensitivity (73.0% vs 61.9%, P < .001) and specificity (88.4% vs 83.0%, P < .001). Conclusion Quantitative assessment with gemstone spectral imaging quantitative parameters showed higher accuracy than qualitative assessment of conventional CT imaging features for preoperative diagnosis of metastatic cervical lymph nodes in patients with papillary thyroid cancer.

    Accurate preoperative staging and restaging of mediastinal lymph nodes in patients with potentially resectable non-small cell lung cancer (NSCLC) is of paramount importance. In 2007, the European Society of Thoracic Surgeons (ESTS) published an algorithm on preoperative mediastinal staging integrating imaging, endoscopic and surgical techniques. Over the last years more evidence of the different mediastinal staging technique has become available. Therefore, a revision of the ESTS guidelines was needed. In case of CT-enlarged or PET-positive mediastinal lymph nodes, tissue confirmation is indicated. Endosonography (EBUS/EUS) with fine needle aspiration is the first choice (when available) since it is minimally invasive and has a high sensitivity to rule in mediastinal nodal disease. If negative, surgical staging with nodal dissection or biopsy is indicated. Video-assisted mediastinoscopy is preferred over mediastinoscopy. The combined use of endoscopic staging and surgical staging results in the highest accuracy. When there are no enlarged lymph nodes on CT and when there is no uptake in lymph nodes on PET or PET-CT, direct surgical resection with systematic nodal dissection is indicated for tumors ?3 cm located in the outer third of the lung. In central tumors or N1 nodes, preoperative mediastinal staging is indicated. The choice between endoscopic staging with EBUS/EUS and fine needle aspiration or video-assisted mediastinoscopy depends on local expertise to adhere to minimal requirements for staging. For tumors larger than 3 cm, preoperative mediastinal staging is advised, mainly in adenocarcinoma with high SUV uptake. PMID:25806304

    Testicular germ cell tumors (TGCTs) commonly metastasize to the lymph node or lung. However, it remains unclear which genes are associated with TGCT metastasis. The aim of this study was to identify gene(s) that promoted human TGCT metastasis. We intraperitoneally administered conditioned medium (CM) from JKT-1, a cell-line from a human testicular seminoma, or JKT-HM, a JKT-1 cell sub-line with high metastatic potential, into mice with JKT-1 xenografts. Administration of CM from JKT-HM significantly promoted lymph node metastasis. A cDNA microarray analysis showed that JKT-HM cells highly expressed the Serpine peptidase inhibitor, clade E, member 2 (SERPINE2), which encodes a secreted protein. Administration of CM from SERPINE2-silenced JKT-HM cells inhibited lymph node metastasis in the xenograft model, compared with administration of CM from JKT-HM cells. There was no significant difference in xenograft volume. Moreover, administration of CM from SERPINE2-over-expressing JKT-1 was likely to promote lymph node metastasis in the xenograft model. There was no difference in the in vitro proliferation or migration of JKT-1 cells cultured with CM from JKT-HM cells, compared to that with CM from JKT-1. There was no promotion of proliferation or lymphangiogenesis in the xenografts, as measured by Ki-67 and LYVE-1 immunohistochemistry, respectively. Although we could not clarify how SERPINE2 promoted lymph node metastasis, it may be a promoter in the development of lymph node metastasis in the human seminoma cells in a mouse xenograft model.

    Context: Total thyroidectomy with central lymph node dissection is recommended in patients with medullary thyroid cancer (MTC). However, the relationship between disease severity and extent of resection on overall survival remains unknown. Objective: The aim of the study was to identify the effect of surgery on overall survival in MTC patients. Methods: Using data from 2968 patients with MTC diagnosed between 1998 and 2005 from the National Cancer Database, we determined the relationship between the number of cervical lymph node metastases, tumor size, distant metastases, and extent of surgery on overall survival in patients with MTC. Results: Older patient age (5.69 [95% CI, 3.34–9.72]), larger tumor size (2.89 [95% CI, 2.14–3.90]), presence of distant metastases (5.68 [95% CI, 4.61–6.99]), and number of positive regional lymph nodes (for ?16 lymph nodes, 3.40 [95% CI, 2.41–4.79]) were independently associated with decreased survival. Overall survival rate for patients with cervical lymph nodes resected and negative, cervical lymph nodes not resected, and 1–5, 6–10, 11–16, and ?16 cervical lymph node metastases was 90, 76, 74, 61, 69, and 55%, respectively. There was no difference in survival based on surgical intervention in patients with tumor size ? 2 cm without distant metastases. In patients with tumor size > 2.0 cm and no distant metastases, all surgical treatments resulted in a significant improvement in survival compared to no surgery (P < .001). In patients with distant metastases, only total thyroidectomy with regional lymph node resection resulted in a significant improvement in survival (P < .001). Conclusions: The number of lymph node metastases should be incorporated into MTC staging. The extent of surgery in patients with MTC should be tailored to tumor size and distant metastases.

    Purpose: To study the absolute number of involved nodes/the number of nodes examined or the nodal ratio (NR) in breast cancer. The primary study endpoint was to evaluate the role of supraclavicular and axillary radiotherapy (SART) according to the NR. Methods and Materials: From the Saskatchewan provincial registry of 1981-1995, the charts of 5,996 consecutive patients were retrieved to collect detailed prognostic factors. Among these patients, 1,985 were node positive. Because the NRs are more reliable the greater the number of nodes examined, we analyzed 1,255 patients with {>=}10 nodes examined. Of these 1,255 patients, 667, 389, and 199 were categorized into three NR groups-low ({<=}25%), medium (>25% to {<=}75%), and high (>75%) nodal involvement, respectively. Results: The NR correlated significantly with the primary tumor size ({<=}2 cm, >2 to {<=}5 cm, and >5 cm; p = 2.2 x 10{sup -16}), clinical stage group (p = 5.5 x 10{sup -16}), pathologic stage group (p < 2.2 x 10{sup -16}), and the risk of any first recurrence (p = 5.0 x 10{sup -15}) using chi-square tests. For a low NR, the 10-year overall survival rate with and without SART was 57% and 58% (p 0.18), and the cause-specific survival rate was 68% and 71% (p = 0.32), respectively. For a medium NR, the 10-year overall survival rate with and without SART was 48% and 34% (p = 0.007), and the cause-specific survival rate was 57% and 43% (p = 0.002), respectively. For a high NR, the 10-year overall survival rate with and without SART was 19% and 10% (p = 0.005), and the cause-specific survival rate was 26% and 14% (p = 0.005), respectively. Conclusion: This is the first study demonstrating that for patients with {>=}10 nodes examined, SART significantly improved the survival for the median and high NR groups but not for the low NR group.

    Patients with chronic lymphocytic leukemia (CLL) have an increased frequency of axillary lymphadenopathy. Pretreatment CT scans can be used to upstage patients at the time of presentation and post-treatment CT scans can reduce the number of complete responses. In the current clinical workflow, the detection and diagnosis of lymph nodes is usually performed manually by examining all slices of CT images, which can be time consuming and highly dependent on the observer's experience. A system for automatic lymph node detection and measurement is desired. We propose a computer aided detection (CAD) system for axillary lymph nodes on CT scans in CLL patients. The lung is first automatically segmented and the patient's body in lung region is extracted to set the search region for lymph nodes. Multi-scale Hessian based blob detection is then applied to detect potential lymph nodes within the search region. Next, the detected potential candidates are segmented by fast level set method. Finally, features are calculated from the segmented candidates and support vector machine (SVM) classification is utilized for false positive reduction. Two blobness features, Frangi's and Li's, are tested and their free-response receiver operating characteristic (FROC) curves are generated to assess system performance. We applied our detection system to 12 patients with 168 axillary lymph nodes measuring greater than 10 mm. All lymph nodes are manually labeled as ground truth. The system achieved sensitivities of 81% and 85% at 2 false positives per patient for Frangi's and Li's blobness, respectively.

    To address the value of qRT-PCR and IHC in accurately detecting lymph node micrometastasis in gynecological cancer, we performed a systematic approach, using a set of dual molecular tumor-specific markers such as cytokeratin 19 (CK19) and carbonic anhydrase 9 (CA9), in a series of 46 patients (19 with cervical cancer, 18 with endometrial cancer, and 9 with vulvar cancer). A total of 1281 lymph nodes were analyzed and 28 were found positive by histopathology. Following this documentation, 82 lymph nodes, 11 positive and 71 negative, were randomly selected and further analyzed both by IHC and qRT-PCR for CK19 and CA9 expression. All 11 (100%) expressed CK19 by IHC, while only 6 (54.5%) expressed CA9. On the contrary, all the histologically negative for micrometastases lymph nodes were also negative by IHC analysis for both markers. The comparative diagnostic efficacy of the two markers using qRT-PCR, however, disclosed that the analysis of the same aliquots of the 82 lymph nodes led to 100% specificity for the CK19 biomarker, while, in contrast, CA9 failed to recapitulate a similar pattern. These data suggest that qRT-PCR exhibits a better diagnostic accuracy compared to IHC, while CK19 displays a consistent pattern of detection compared to CA9. PMID:24527437

    Objective To study explores the effect of HLEC on the secreted proteins of epithelial ovarian cancer (EOC) cells (SKOV3-PM4) with directional highly lymphatic metastasis. Methods Supernatants of four groups of cultured cells, namely, SKOV3 (A), SKOV3+HLEC (B), SKOV3-PM4 (C), SKOV3-PM4+HLEC (D), were collected, and their proteins were detected by antibody arrays and iTRAQ-2D-LC-MALDI-TOF/TOF/MS. Significantly differential proteins were further analyzed via bioinformatics and validated in human serums and cell media via ELISA. Results Results of antibody arrays and mass spectrometry demonstrated that GRN and VEGFA were upregulated in group C (compared with group A), whereas IGFBP7 and SPARC were downregulated in group D (compared with group C). Comprehensive bioinformatics analysis results showed that IGFBP7 and VEGFA were closely linked to each other. Further validation with serums showed statistical significance in VEGFA and IGFBP7 levels among groups of patients with ovarian cancers, benign tumors, and control groups. Two proteins were upegulated in the first group. VEGFA in the control group was downregulated. For IGFBP, upregulation in the control group and down-regulation in the first group were also observed. Conclusion The HLEC microenvironment is closely associated with directional metastasis to lymph nodes and with differential proteins including cell stromal proteins and adhesion factors. The upregulation of VEGFA and GRN and the downregulation of SPARC and IGFBP7 are closely associated with directional metastasis to lymph nodes in EOC cells. PMID:24349832

    Inflammation plays key roles at various stages of tumor development, including invasion and metastasis. In mice, the angiopoietin-like protein (ANGPTL2) gene has been implicated in inflammatory carcinogenesis. ANGPTL2 mRNA expression was investigated by real-time polymerase chain reaction (RT-PCR) assay using LightCycler in surgically treated non-small cell lung cancer (NSCLC) cases. In total, 110 surgically resected NSCLC cases were used for mRNA level analyses. The ANGPTL2/?-actin mRNA levels were not significantly different between lung cancer (1598.481±6465.781) and adjacent normal lung tissues (2116.639±8337.331, P=0.5453). The tumor/normal (T/N) ratio of ANGPTL2/?-actin mRNA levels was not different between gender, age, smoking status and pathological stages. The T/N ratio of ANGPTL2/?-actin mRNA levels was significantly higher in lymph node metastasis-positive cases (2.173±3.151) compared with lymph node metastasis-negative cases (1.212±1.778, P=0.0464). However, ANGPTL2 mRNA status was not correlated with tumor invasion status. Thus, ANGPTL2 may drive metastasis and provide a candidate for blockade of its function as a strategy to antagonize the metastatic process in NSCLC. PMID:23205131

    Tumor budding, a histological hallmark of epithelial-mesenchymal transition in colorectal cancer, is a parameter of tumor progression and according to the International Union Against Cancer/American Joint Committee on Cancer an 'additional' prognostic factor. The current definition of tumor budding is reserved for the invasive tumor front of colorectal cancer (so called peri-tumoral budding), but tumor buds can also be observed in small preoperative biopsy specimens. Whereas the prognostic value of peri-tumoral budding assessed in resection specimens has found wide acceptance, the value of budding in preoperative biopsies, which normally do not encompass the invasive tumor margin and hence can be called intra-tumoral budding, has not been systematically investigated yet. Therefore, the aim of this study is to assess the predictive value of intra-tumoral budding for lymph node and distant metastasis in preoperative biopsies. Preoperative biopsy samples and consecutive resection specimens from 72 patients with pathological information on TNM stage, vascular, lymphatic and perineural invasion, and tumor border configuration were used to evaluate intra-tumoral budding and peri-tumoral budding. Both parameters were scored semiquantitatively as 'high' (detectable at low power magnification × 2.5) and 'low' (occasional budding at intermediate magnification × 10, difficult to find or absent). In biopsy samples high intra-tumoral budding was observed in 12/72 patients (17%) and associated with high peri-tumoral budding in the corresponding resection specimens (P=0.008). Additionally, there was a correlation between high intra-tumoral budding and lymph node metastasis (P=0.034), distant metastasis (P=0.007) and higher tumor grade (P=0.025). Peri-tumoral budding was associated with higher N stage (P=0.004), vascular (P=0.046) and lymphatic invasion (P=0.019) as well as with an infiltrating tumor border (P<0.001), reflecting the predictive power of peri-tumoral budding for tumor progression. High intra-tumoral budding in preoperative biopsy samples of colorectal cancer patients predicts high peri-tumoral budding at the invasive margin and lymph node metastasis in the corresponding resection specimens as well as distant metastasis.

    The objectives of the study were to evaluate the performance of sentinel lymph node biopsy (SLNB) in detecting occult metastases in papillary thyroid carcinoma (PTC) and to correlate their presence to tumor and patient characteristics. Twenty-three clinically node-negative PTC patients (21 females, mean age 48.4 years) were prospectively enrolled. Patients were submitted to sentinel lymph node (SLN) lymphoscintigraphy prior to total thyroidectomy. Ultrasound-guided peritumoral injections of (99m)Tc-phytate (7.4 MBq) were performed. Cervical single-photon emission computed tomography and computed tomography (SPECT/CT) images were acquired 15 min after radiotracer injection and 2 h prior to surgery. Intra-operatively, SLNs were located with a gamma probe and removed along with non-SLNs located in the same neck compartment. Papillary thyroid carcinoma, SLNs and non-SLNs were submitted to histopathology analysis. Sentinel lymph nodes were located in levels: II in 34.7 % of patients; III in 26 %; IV in 30.4 %; V in 4.3 %; VI in 82.6 % and VII in 4.3 %. Metastases in the SLN were noted in seven patients (30.4 %), in non-SLN in three patients (13.1 %), and in the lateral compartments in 20 % of patients. There were significant associations between lymph node (LN) metastases and the presence of angio-lymphatic invasion (p = 0.04), extra-thyroid extension (p = 0.03) and tumor size (p = 0.003). No correlations were noted among LN metastases and patient age, gender, stimulated thyroglobulin levels, positive surgical margins, aggressive histology and multifocal lesions. Sentinel lymph node biopsy can detect occult metastases in PTC. The risk of a metastatic SLN was associated with extra-thyroid extension, larger tumors and angio-lymphatic invasion. This may help guide future neck dissection, patient surveillance and radioiodine therapy doses. PMID:24695942

    We are reporting a case of a 34-year-old woman with occult primary breast cancer discovered after initially presenting with neurological symptoms. She was successfully treated with neoadjuvant chemotherapy followed by definitive axillary lymph node dissection and ipsilateral whole breast radiotherapy. The case presented is unique due to the rarity of occult primary breast cancer, especially in light of her initial confounding neurological signs and symptoms, which highlights the importance of careful staging.

    Aims. A trend towards local excision of early rectal cancers has prompted us to investigate if immunoprofiling might help in predicting lymph node involvement in this subgroup. Methods. A tissue microarray of 126 biopsies of early rectal cancer (T1 and T2) was stained for several immunomarkers of the innate and the adaptive immune response. Patients' survival and nodal status were analyzed and correlated with infiltration of the different immune cells. Results. Of all tested markers, only CD8 (P = 0.005) and TIA-1 (P = 0.05) were significantly more frequently detectable in early rectal cancer biopsies of node negative as compared to node positive patients. Although these two immunomarkers did not display prognostic effect “per se,” CD8+ and, marginally, TIA-1 T cell infiltration could predict nodal involvement in univariate logistic regression analysis (OR 0.994; 95% CI 0.992–0.996; P = 0.009 and OR 0.988; 95% CI 0.984–0.994; P = 0.05, resp.). An algorithm significantly predicting the nodal status in early rectal cancer based on CD8 together with vascular invasion and tumor border configuration could be calculated (P < 0.00001). Conclusion. Our data indicate that in early rectal cancers absence of CD8+ T-cell infiltration helps in predicting patients' nodal involvement. PMID:25609852

    Purpose: To compare treatment-related outcomes and toxicity for patients with axillary lymph node metastases from malignant melanoma treated with postoperative radiation therapy (RT) to either the axilla only or both the axilla and supraclavicular fossa (extended field [EF]). Methods and Materials: The medical records of 200 consecutive patients treated with postoperative RT for axillary lymph node metastases from malignant melanoma were retrospectively reviewed. All patients received postoperative hypofractionated RT for high-risk features; 95 patients (48%) received RT to the axilla only and 105 patients (52%) to the EF. Results: At a median follow-up of 59 months, 111 patients (56%) had sustained relapse, and 99 patients (50%) had died. The 5-year overall survival, disease-free survival, and distant metastasis-free survival rates were 51%, 43%, and 46%, respectively. The 5-year axillary control rate was 88%. There was no difference in axillary control rates on the basis of the treated field (89% for axilla only vs. 86% for EF; p = 0.4). Forty-seven patients (24%) developed treatment-related complications. On both univariate and multivariate analyses, only treatment with EF irradiation was significantly associated with increased treatment-related complications. Conclusions: Adjuvant hypofractionated RT to the axilla only for metastatic malignant melanoma with high-risk features is an effective method to control axillary disease. Limiting the radiation field to the axilla only produced equivalent axillary control rates to EF and resulted in lower treatment-related complication rates.

    Background The aim was to evaluate whether extended-field concurrent chemoradiation (EF-CCRT) leads to results better than those obtained by standard whole-pelvis concurrent chemoradiation (WP-CCRT) in locally advanced cervical cancer with radiologic negative paraaortic lymph nodes (PALNs). Patients and methods A total of 102 patients with histopathologically proven squamous cell carcinoma, adenocarcinoma, or adenosquamous cell carcinoma, and radiologic negative PALN locally advanced cervical cancer, stage IIB-IVA, were accrued between July 2007 and April 2008 and were randomly assigned to WP-CCRT (50 patients) or EF-CCRT (52 patients), followed by high-dose rate brachytherapy. Data regarding the safety profile, response rates, and occurrence of local, PALN, or distant failure were recorded. Results During a median follow-up time of 60 months (18–66), 74/102 patients completed the treatment protocol and were analyzed. Overall PALN, distant-metastasis control, disease-free survival, and overall survival rates were 97.1%, 86.9%, 80.3%, and 72.4% in EF-CCRT respectively in comparison with WP-CCRT (82.1%,74.7%, 69.1%, and 60.4%), with P-values of 0.02, 0.03, 0.03 and 0.04 respectively. No difference in acute toxicity profile was seen between the groups, and late toxicities were mild and minimal. Conclusion Prophylactic EF-CCRT can be a reasonable option in patients with locally advanced cervical cancer with radiologic positive pelvic lymph nodes and radiologic negative PALN. PMID:25228820

    Purpose: To compare high dose rate (HDR) point B to pelvic lymph node dose using three-dimensional-planned brachytherapy for cervical cancer. Methods and Materials: Patients with FIGO Stage IB-IIIB cervical cancer received 70 tandem HDR applications using CT-based treatment planning. The obturator, external, and internal iliac lymph nodes (LN) were contoured. Per fraction (PF) and combined fraction (CF) right (R), left (L), and bilateral (Bil) nodal doses were analyzed. Point B dose was compared with LN dose-volume histogram (DVH) parameters by paired t test and Pearson correlation coefficients. Results: Mean PF and CF doses to point B were R 1.40 Gy +- 0.14 (CF: 7 Gy), L 1.43 +- 0.15 (CF: 7.15 Gy), and Bil 1.41 +- 0.15 (CF: 7.05 Gy). The correlation coefficients between point B and the D100, D90, D50, D2cc, D1cc, and D0.1cc LN were all less than 0.7. Only the D2cc to the obturator and the D0.1cc to the external iliac nodes were not significantly different from the point B dose. Significant differences between R and L nodal DVHs were seen, likely related to tandem deviation from irregular tumor anatomy. Conclusions: With HDR brachytherapy for cervical cancer, per fraction nodal dose approximates a dose equivalent to teletherapy. Point B is a poor surrogate for dose to specific nodal groups. Three-dimensional defined nodal contours during brachytherapy provide a more accurate reflection of delivered dose and should be part of comprehensive planning of the total dose to the pelvic nodes, particularly when there is evidence of pathologic involvement.

    The accurate detection of the presence of lymph node metastases (LNM) of gastric cancers (GCs) is useful for the implementation of necessary and sufficient treatment, but current methods of detection are unsatisfactory. In the present study, we focused on DNA methylation markers since they have several advantages, including biological and chemical stability and informativeness even in the presence of contaminating cells. Using three metastatic lymph nodes and three primary GCs without LNM, methylation bead array analyses were performed, which enabled the interrogation of 485,577 CpG sites. A total of 31 CpG sites that were hypermethylated in the metastatic lymph nodes, compared with the GCs without LNM, were isolated. Using primary GCs with and without LNM (28 GCs with LNM and 10 without), their methylation levels were measured using quantitative PCR following treatment with sodium bisulfite or a methylation-sensitive restriction enzyme. Of the genomic regions around the 31 CpG sites, 10 regions demonstrated higher methylation levels in the GCs with LNM compared with the GCs without LNM (P<0.05). Finally, the hypermethylation of the 10 regions was validated using another set of samples (129 GCs with LNM and 20 without). Hypermethylation of the region around the cg06436185 CpG site predicted the presence of LNM at a sensitivity of 43% and specificity of 85%. Additionally, the hypermethylation of the region was associated with a poor survival rate among GC patients with LNM. The results of the present study indicated that the methylation status of the region was a promising candidate marker to detect the presence of LNM of GCs and may reflect the malignant potential of GCs.

    Background: This study evaluates the relation of the early oestrogen-regulated gene gabarapl1 to cellular growth and its prognostic significance in breast adenocarcinoma. Methods: First, the relation between GABARAPL1 expression and MCF-7 growth rate was analysed. Thereafter, by performing macroarray and reverse transcriptase quantitative-polymerase chain reaction (RT–qPCR) experiments, gabarapl1 expression was quantified in several histological breast tumour types and in a retrospective cohort of 265 breast cancers. Results: GABARAPL1 overexpression inhibited MCF-7 growth rate and gabarapl1 expression was downregulated in breast tumours. Gabarapl1 mRNA levels were found to be significantly lower in tumours presenting a high histological grade, with a lymph node-positive (pN+) and oestrogen and/or progesterone receptor-negative status. In univariate analysis, high gabarapl1 levels were associated with a lower risk of metastasis in all patients (hazard ratio (HR) 4.96), as well as in pN+ patients (HR 14.96). In multivariate analysis, gabarapl1 expression remained significant in all patients (HR 3.63), as well as in pN+ patients (HR 5.65). In univariate or multivariate analysis, gabarapl1 expression did not disclose any difference in metastasis risk in lymph node-negative patients. Conclusions: Our data show for the first time that the level of gabarapl1 mRNA expression in breast tumours is a good indicator of the risk of recurrence, specifically in pN+ patients. PMID:20197771

    Purpose: Use of postmastectomy radiation therapy (PMRT) in breast cancer patients with 1-3 positive nodes is controversial. The objective of this study was to determine whether the size of nodal metastases in this subset could predict who would benefit from PMRT. Methods and Materials: We analyzed 250 breast cancer patients with 1-3 positive nodes after mastectomy treated with contemporary surgery and systemic therapy at our institution. Of these patients, 204 did not receive PMRT and 46 did receive PMRT. Local and regional recurrence risks were stratified by the size of the largest nodal metastasis measured as less than or equal to 5 mm or greater than 5 mm. Results: The median follow-up was 65.6 months. In the whole group, regional recurrences occurred in 2% of patients in whom the largest nodal metastasis measured 5 mm or less vs 6% for those with metastases measuring greater than 5 mm. For non-irradiated patients only, regional recurrence rates were 2% and 9%, respectively. Those with a maximal nodal size greater than 5 mm had a significantly higher cumulative incidence of regional recurrence (P=.013). The 5-year cumulative incidence of a regional recurrence in the non-irradiated group was 2.7% (95% confidence interval [CI], 0.7%-7.2%) for maximal metastasis size of 5 mm or less, 6.9% (95% CI, 1.7%-17.3%) for metastasis size greater than 5 mm, and 16% (95% CI, 3.4%-36.8%) for metastasis size greater than 10 mm. The impact of the maximal nodal size on regional recurrences became insignificant in the multivariable model. Conclusions: In patients with 1-3 positive lymph nodes undergoing mastectomy without radiation, nodal metastasis greater than 5 mm was associated with regional recurrence after mastectomy, but its effect was modified by other factors (such as tumor stage). The size of the largest nodal metastasis may be useful to identify high-risk patients who may benefit from radiation therapy after mastectomy.

    Metastatic lymph node density (ND) has been reproducibly proven to be a prognostic factor in gastric cancer. The molecular mechanisms that underlie this aggressiveness are underexplored. Here, we aimed to identify molecules associated with this unique phenotype. Tumor specimens from patients with stage III gastric cancer with high or low ND (n = 4 for both) were compared at the mRNA level using Affymetrix microarray (harboring 54,675 genes). The expression data were prioritized, and genes that correlated with ND were selected. Ultimately, the EGFR was validated as such a candidate molecule in patients with primary advanced gastric cancer who underwent standard treatment (n = 167). Expression data of the microarray were prioritized based on gene expression ratio and frequency of gene expression. The first priority genes to be selected were genes that are known to be amplified in cancer, which included NKX2.1, CHST9, CTNND2, SLC25A27, FGFR2, EGFR, and PTGER1. Of these genes, the EGFR gene was of particular interest. EGFR expression in primary gastric cancer was examined using immunohistochemistry (IHC). The Student's t-test elucidated a significant difference in EGFR expression between IHC 2+/3+ and IHC 1+ according to ND (P = 0.0035). The Chi-square test also indicated a significant difference between high and low levels of EGFR immunohistochemical staining (IHC2+/3+ and IHC1+, respectively) and ND status (P = 0.0023). According to the least squares method, as ND increased, the risk that EGFR staining levels changed from IHC 1+ to IHC 2+ also increased. In this study, we determined that high EGFR expression may underlie the aggressive mechanism of advanced gastric cancer with high ND. PMID:25154973

    Aim The aim of the study was to compare the number of nodes dissected during laparoscopic and open radical cystoprostatectomy in men or anterior exenteration in women due to muscle invasive bladder urothelial cancer (IBC). Material and methods Fifty-one patients treated with laparoscopic radical cystectomy (LRC) and 63 with open radical cystectomy (ORC) were compared. The LRC group consisted of 47 pT2 tumours and 4 pT3, while the ORC group was composed of 27 pT2 tumours and 36 pT3. During ORC external, internal, common iliac and obturator lymph nodes were removed separately, but were added and analysed together for each side. Nodes dissected from one side during ORC were compared to en bloc dissected nodes in the LRC group. Results There were no complications associated with extended pelvic lymph node dissection during LRC or ORC. There were significant differences in the mean number of resected lymph nodes between LRC and ORC for pT2 tumours. The laparoscopic approach allowed about 8-9 more lymph nodes to be removed than open surgery in the pT2 group. In 15% of patients with pT2 disease treated with open radical cystectomy node metastases were observed. Active disease was detected in 18% of nodes resected laparoscopically due to pT2 disease. Fourty-seven percentage of patients with pT3 disease treated with open surgery were diagnosed as harbouring metastatic lymph nodes. The laparoscopic group with pT3 disease was too small to analyse. Conclusions We have found that laparoscopic radical cystectomy can be performed without any compromise in lymph node dissection. The technique of lymph node dissection (LND) during laparoscopic cystectomy (LRC) resulted in sufficient resected lymphatic tissue, especially in patients with bladder-confined tumours with a low volume of lymph nodes.

    The performance of a lymph-node detection system used with a high- Tc superconducting quantum interference device was investigated. Ultra-small iron oxide particles containing 360 pg in weight of iron could be detected at a distance of 1 mm using Helmholtz coils. When a pair of angled field coils, which were of a more practical design, were used this value was increased to 2.8 ng. This value is still large enough to apply the technique for sentinel-node biopsy and lymphatic mapping.

    2012-01-01

    Background Different ethnicities have different distribution of Duffy blood group (DBG) phenotypes and different breast cancer morbidity. A study in our lab demonstrated that Duffy antigen/receptor for chemokines (DARC, also known as DBGP, the Duffy protein phenotype), led to the inhibition of tumorigenesis. Therefore, we tested the hypothesis that DBGP is correlated with breast cancer occurrence. Methods DBGP proteins were examined by indirect antiglobulin testing with anti-FYa and anti-FYb antibodies. The phenotypes were classified into four groups according to the agglutination reactions: FYa + FYb+, FYa + FYb-, FYa-FYb + and FYa-FYb-. The phenotypes and pathological diagnosis of consecutively hospitalized female patients (n = 5,022) suffering from breast cancer at the Shanghai Cancer Hospital and Henan Province Cancer Hospital were investigated. The relationships between DBGP expression with breast cancer occurrence, axillary lymph status, histological subtype, tumor size pathological grade and overall survival were analyzed. Results The incidence of breast cancer was significantly different between FYa + FYb + (29.8%), FYa + FYb- (33.2%), FYa-FYb + (45.6%) and FYa-FYb- (59.1%; P = 0.001). Significant different numbers of breast cancer patients had metastases to the axillary lymph nodes in the FYa + FYb + group (25.1%), FYa + FYb- (36.9%), FYa-FYb + (41.0%) and FYa-FYb- (50.0%, (P = 0.005). There was a statistical significance (p = 0.022) of the overall survival difference between patients with difference phenotypes. No significant difference was observed in cancer size (t-test, p > 0.05), histological cancer type (Fisher's exact test, p > 0.05) or histological grade (Fisher's exact test, p > 0.05) between every each DBGP group. Conclusions DBGP is correlated with breast cancer incidence and axillary lymph node metastasis and overall survival. Further investigations are required to determine the underlying mechanism of Duffy blood group phenotype on breast cancer risk. PMID:22928984

    Purpose The aim of this study is to describe our initial experience and assess the feasibility and safety of robotic and laparoscopic lateral pelvic node dissection (LPND) in advanced rectal cancer. Methods Between November 2007 and November 2012, extended minimally invasive surgery for LPND was performed in 21 selected patients with advanced rectal cancer, including 11 patients who underwent robotic LPND and 10 who underwent laparoscopic LPND. Extended lymphadenectomy was performed when LPN metastasis was suspected on preoperative magnetic resonance imaging even after chemoradiation. Results All 21 procedures were technically successful without the need for conversion to open surgery. The median operation time was 396 minutes (range, 170-581 minutes) and estimated blood loss was 200 mL (range, 50-700 mL). The median length of stay was 10 days (range, 5-24 days) and time to removal of the urinary catheter was 3 days (range, 1-21 days). The median total number of lymph nodes harvested was 24 (range, 8-43), and total number of lateral pelvic lymph nodes was 7 (range, 2-23). Six patients (28.6%) developed postoperative complications; three with an anastomotic leakages, two with ileus and one patient with chyle leakage. Two patients (9.5%) developed urinary incontinence. There was no mortality within 30 days. During a median follow-up of 14 months, two patients developed lung metastasis and there was no local recurrence. Conclusion Robotic and laparoscopic LPND is technically feasible and safe. Minimally invasive techniques for LPND in selected patients can be an acceptable alternative to an open LPND. PMID:24761412

    Assessment of the sentinel lymph node (SLN) in patients with early stage breast cancer is vital in selecting the appropriate surgical approach. However, the existing methods, including methylene blue and nuclides, possess low efficiency and effectiveness in mapping SLNs, and to a certain extent exert side effects during application. Indocyanine green (ICG), as a fluorescent dye, has been proved reliable usage in SLN detection by several other groups. In this paper, we introduce a novel surgical navigation system to detect SLN with ICG. This system contains two charge-coupled devices (CCD) to simultaneously capture real-time color and fluorescent video images through two different bands. During surgery, surgeons only need to follow the fluorescence display. In addition, the system saves data automatically during surgery enabling surgeons to find the registration point easily according to image recognition algorithms. To test our system, 5 mice and 10 rabbits were used for the preclinical setting and 22 breast cancer patients were utilized for the clinical evaluation in our experiments. The detection rate was 100% and an average of 2.7 SLNs was found in 22 patients. Our results show that the usage of our surgical navigation system with ICG to detect SLNs in breast cancer patients is technically feasible. PMID:24358319

    Background and Aims There is a discrepancy between the American Joint Committee on Cancer (AJCC) guidelines (7th edition) and the Japanese treatment guidelines (3rd edition) with regard to the extent of D2 lymphadenectomy for gastric cancer. In the AJCC, hepatic artery station (No.12a) lymph node (LN) metastasis is classified as distant metastasis, whereas in the Japanese guidelines, this classified is regional metastasis. This study aimed to evaluate whether it is appropriate to reclassify No.12a LN metastasis as distant metastasis in consideration of survival outcome. Methods In this retrospective analysis, data from patients with gastric cancer who underwent regular D2 or greater lymphadenectomy between 1996 and 2006 were evaluated to determine any association between the clinicopathological features of hepatic artery LNs and survival prognosis. Results Among the 247 patients with gastric cancer who underwent No.12 LN harvest, 45 (18.2%) were positive for No.12a LN metastasis. No.12a LN metastasis was significantly associated with poor clinicopathological features, advanced tumor stage, and poor overall survival. The 5-year survival rate of patients with No.12a LN metastasis was significantly better than that of patients with distant metastasis (P < 0.05), but was similar to that of patients with LN involvement in the D2 lymphadenectomy region (P > 0.05). No.12a LN metastasis was shown to significantly influence survival outcome in univariate analysis, but was not identified as a significant independent predictor in multivariate analysis. In logistic multivariate regression analysis, T stage, N stage, and station No.3, 5, and 6 LN metastasis were independent predictors of No.12a LN involvement. Conclusions It is inappropriate to reclassify No.12a LN metastasis as distant metastasis. We propose that this be considered as regional metastasis and be included in the extent of D2 lymphadenectomy to improve survival outcomes in patients with gastric cancer. PMID:25768441

    Lymph node (LN) harvest is influenced by several factors, including tumor genetics. Microsatellite instability (MSI) is associated with improved node harvest, but the association to other genetic factors is largely unknown. Research methods included a prospective series of stage I–III colon cancer patients undergoing ex vivo sentinel-node sampling. The presence of MSI, KRAS mutations in codons 12 and 13, and BRAF V600E mutations was analyzed. Uni- and multivariate regression models for node sampling were adjusted for clinical, pathological and molecular features. Of 204 patients, 67% had an adequate harvest (?12 nodes). Adequate harvest was highest in patients whose tumors exhibited MSI (79%; odds ratio [OR] 2.5, 95% confidence interval [CI] 1.2–4.9; P = 0.007) or were located in the proximal colon (73%; 2.8, 1.5–5.3; P = 0.002). In multiple linear regression, MSI was a significant predictor of the total LN count (P = 0.02). Total node count was highest for cancers with MSI and no KRAS/BRAF mutations. The independent association between MSI and a high LN count persisted for stage I and II cancers (P = 0.04). Tumor location in the proximal colon was the only significant predictor of an adequate LN harvest (adjusted OR 2.4, 95% CI 1.2–4.9; P = 0.01). An increase in the total number of nodes harvested was not associated with an increase in nodal metastasis. In conclusion, number of nodes harvested is highest for cancers of the proximal colon and with MSI. The nodal harvest associated with MSI is influenced by BRAF and KRAS genotypes, even for cancers of proximal location. Mechanisms behind the molecular diversity and node yield should be further explored. PMID:23979710

    A 74-year-old man was diagnosed with advanced gastric cancer(cStage III B). Laparotomy showed N2 lymph node metastasis and pancreatic invasion. Radical resection appeared impossible and was thus not performed. Chemotherapy consisting of a combination of S-1(80mg/m 2, 2-week administration and 1-week rest), and docetaxel(40mg/m2day 1)was administered with the expectation of tumor downstaging. A partial response(PR)was obtained after five courses of this regimen in which the primary lesion and lymph node swelling remarkably improved. Total gastrectomy, splenectomy, partial colectomy, and D2 lymph node dissection were then performed. Pathological analysis revealed very few cancer cells in the primary lesion and that the lymph nodes had become scarred and fibrotic. The histological appearance was judged to be grade 2 and the final diagnosis was T1N0H0P0CY0M0, fStage I A, curability A. Currently, more than 6 years and 4 months after the operation, the patient is alive without any evidence of recurrence. Thus, docetaxel/S-1 combination therapy was an effective neoadjuvant chemotherapy for this case of advanced gastric cancer. PMID:25132034

    Purpose: To determine whether the use of intensity-modulated radiotherapy (IMRT) would lead to improved dosimetry for the breast and regional nodes. Methods and Materials: Ten patients with left-sided breast cancer were selected. The clinical target volume included left breast and internal mammillary (IM), supraclavicular (SC), and axillary (AX) nodes. The critical structures included heart, right and left lungs, contralateral breast, esophagus, thyroid, and humeral head. Conventional and a series of IMRT plans were generated for comparison. Results: The average heart D{sub 3} was reduced from 31.4 {+-} 18.9 with three-dimensional conformal radiotherapy (3D-CRT) to 15 {+-} 7.2 Gy with 9-field (9-FLD IMRT). The average left lung D{sub 30} was also decreased from 27.9 {+-} 11.5 Gy (3D-CRT) to 12.6 {+-} 8.2 Gy (9-FLD IMRT). The average contralateral breast D{sub 2} was reduced from 4.4 {+-} 5.3 Gy (3D-CRT) to 1.8 {+-} 1.2 Gy (4-FLD IMRT). Esophagus D{sub 2} was increased from 9.3 {+-} 8.1 Gy (3D-CRT) to 29.4 {+-} 5.4 (9-FLD IMRT); thyroid D{sub 50} was increased from 0.9 {+-} 0.6 Gy (3D-CRT) to 11.9 {+-} 6.6 (9-FLD IMRT); humeral head D{sub 2} was increased from 36.1 {+-} 13.1 Gy (3D-CRT) to 39.9 {+-} 6.5 (9-FLD IMRT). Conclusions: The use of IMRT improves breast and regional node coverage while decreasing doses to the lungs, heart, and contralateral breast when compared with 3D-CRT. Doses to esophagus, thyroid, and humeral head, however, were increased with IMRT.

    Sentinel lymph node biopsy (SLNB), a less invasive alternative to axillary lymph node dissection (ALND), has become the standard of care for patients with clinically node-negative breast cancer. In SLNB, lymphatic mapping with radio-labeled sulfur colloid and/or blue dye helps identify the sentinel lymph node (SLN), which is most likely to contain metastatic breast cancer. Even though SLNB, using both methylene blue and radioactive tracers, has a high identification rate, it still relies on an invasive surgical procedure, with associated morbidity. In this study, we have demonstrated a non-invasive single-walled carbon nanotube (SWNT)-enhanced photoacoustic (PA) identification of SLN in a rat model. We have successfully imaged the SLN in vivo by PA imaging (793 nm laser source, 5 MHz ultrasonic detector) with high contrast-to-noise ratio (=89) and good resolution ( approximately 500 microm). The SWNTs also show a wideband optical absorption, generating PA signals over an excitation wavelength range of 740-820 nm. Thus, by varying the incident light wavelength to the near infrared region, where biological tissues (hemoglobin, tissue pigments, lipids and water) show low light absorption, the imaging depth is maximized. In the future, functionalization of the SWNTs with targeting groups should allow the molecular imaging of breast cancer. PMID:19430111

    Most diagnosed early stage breast cancer cases are treated by lumpectomy and adjuvant radiation therapy, which significantly decreases the locoregional recurrence but causes inevitable toxicity to normal tissue. By using a technique of preparing liposomes carrying technetium-99m (99mTc), rhenium-186 (186Re), or rhenium-188 (188Re) radionuclides, as well as chemotherapeutic agents, or their combination, for cancer therapy with real time image-monitoring of pharmacokinetics and prediction of therapy effect, this study investigated the potential of a novel targeted focal radiotherapy with low systemic toxicity using radioactive immunoliposomes to treat both the surgical cavity and draining lymph nodes in a rat breast cancer xenograft positive surgical margin model. Immunoliposomes modified with either panitumumab (anti-EGFR), or bevacizumab (anti-VEGF) were remote loaded with 99mTc diagnostic radionuclide, and injected into the surgical cavity of female nude rats with positive margins post lumpectomy. Locoregional retention and systemic distribution of 99mTc-immunoliposomes were investigated by nuclear imaging, stereofluorescent microscopic imaging and gamma counting. Histopathological examination of excised draining lymph nodes was performed. The locoregional retention of 99mTc-immunoliposomes in each animal was influenced by the physiological characteristics of surgical site of individual animals. Panitumumab- and bevacizumab-liposome groups had higher intracavitary retention compared with the control liposome groups. Draining lymph node uptake was influenced by both the intracavitary radioactivity retention level and metastasis status. Panitumumab-liposome group had higher accumulation on the residual tumor surface and in the metastatic lymph nodes. Radioactive liposomes that were cleared from the cavity were metabolized quickly and accumulated at low levels in vital organs. Therapeutic radionuclide-carrying specifically targeted panitumumab- and bevacizumab- liposomes have increased potential compared to non-antibody targeted liposomes for post-lumpectomy focal therapy to eradicate remaining breast cancer cells inside the cavity and draining lymph nodes with low systemic toxicity.

    Purpose: Extracapsular spread (ECS) in neck lymph nodes is a major adverse prognostic factor in patients with oral cavity squamous cell carcinoma (OSCC). We conducted a retrospective analysis of prognostic factors in this patient group and tried to identify a subset of patients with a worse prognosis suitable for more aggressive therapeutic interventions. Methods and Materials: Enrolled in the study were 255 OSCC patients with ECS in neck nodes and without evidence of distant metastasis. All participants were followed-up for at least 2 years or censored at last follow-up. The 5-year rates of control, distant metastasis, and survival were the main outcome measures. Results: Level IV/V lymph node metastases and tumor depth {>=}12 mm were independent predictors of 5-year survival and identified three prognostic groups. In the low-risk group (no level IV/V metastases and tumor depth <12 mm), the 5-year disease-free, disease-specific, and overall survival rates were 60%, 66%, and 50%, respectively. In the intermediate-risk group (no level IV/V metastases and tumor depth {>=}12 mm), the 5-year disease-free, disease-specific, and overall survival rates were 39%, 41%, and 28%, respectively. In the high-risk group (evidence of level IV/V metastases), the 5-year disease-free, disease-specific, and overall survival rates were 14%, 12%, and 10%, respectively. Conclusions: Among OSCC patients with ECS, those with level IV/V metastases appear to have the worst prognosis followed by without level IV/V metastases and tumor depth {>=}12 mm. An aggressive therapeutic approach may be suitable for intermediate- and high-risk patients.

    The diagnosis of cervical squamous cell carcinoma with concurrent T-cell rich B cell lymphoma in dissected lymph nodes has not been reported to our knowledge. In our case, the biopsy of an exophytic lesion at the uterine cervix showed squamous cell carcinoma in a 50-year-old woman presenting with postcoital bleeding. Type III hysterectomy, bilateral salpingo-oophorectemy, bilateral pelvic, para-aortic lymph node dissections were performed. Pathologic examination revealed a T-cell rich B cell lymphoma in some lymph nodes beside squamous cell carcinoma in several of others. ELISA for human immuno-deficiency virus (HIV) was negative. The cervical carcinoma was staged as FIGO clinical stage IB1 and the lymphoma as Ann Arbor IIA. Six cycles of CHOP (cyclophosphamide, adriamycin, vincristine, and prednisolon) chemotherapy for the lymphoma and concomitant pelvic chemoradiotherapy with cisplatin for cervical cancer were given. In this rare coincidence, the best available therapy for each of the diseases should be considered individually. We also suggest that HIV screennig test be carried out, because both diseases may be related to human immuno-deficiency virus, although our patient is HIV-negative. PMID:14675356

    MicroRNAs (miRNAs) play a critical role in gastric cancer progression and metastasis. This study investigated the role of miRNA-135a in early gastric cancer (EGC) including lymph node (LN) metastasis. We examined the correlation between miRNA-135a expression and clinical outcomes in 59 patients who underwent surgery for EGC. Using gastric cancer cell lines, we performed functional and target gene analyses. miRNA-135a expression was down-regulated in 33.9% of patients. These patients showed a significantly more advanced stage (TNM stage?IB, 35.0% vs. 12.8%, p?=?0.045) and higher rate of LN metastasis (30.0% vs. 5.1%, p?=?0.014) than those with up-regulation of miRNA-135a expression. In a multivariate analysis, down-regulation of miRNA-135a was an independent risk factor for LN metastasis (adjusted odds ratio, 8.04; 95% confidence interval, 1.08–59.81; p?=?0.042). Functional analyses using gastric cancer cell lines showed that miRNA-135a suppressed cell viability, epithelial-mesenchymal transition, cell invasion, and migration. ROCK1 was a target of miRNA-135a and its expression was inversely correlated to that of miRNA-135a. ROCK1 expression was significantly increased in EGC patients with LN metastasis than in those without LN metastasis. Our results confirm the tumor-suppressive role of miRNA-135a, and demonstrate its role in LN metastasis in EGC. miRNA-135a and its target gene ROCK1 may be novel therapeutic and prognostic targets for EGC.

    Sentinel Lymph Node (SLN) biopsy using a combination of radioisotopes and blue dyes have a good accuracy rate in predicting subclinical neck nodal metastases in head and neck cancers. However, the limited availability of lymphoscintigraphy facilities in India requires exploration of alternative methods of SLN detection. We evaluated the feasibility of using methylene blue dye alone in detecting SLN in cN0 early oral cancers. 32 patients with cN0 early (T1, T2) oral squamous cell cancers underwent SLN biopsy using peri tumoural methylene blue dye injection. Blue dye stained (SLN) nodes were sent for frozen section analyses. Patients who had microscopic metastases in SLN underwent modified radical neck dissections and the rest underwent selective neck dissections. Paraffin sections and IHC studies were done on all nodes. SLN was identified in 29 patients (Identification rate?=?90.6 %) of which SLN was positive for metastases on frozen section in 5 patients. The sensitivity, specificity and NPV of SLN with frozen section were 80 %, 95.8 % and 95.8 % respectively. IHC with cytokeratins increased the sensitivity (100 %) and NPV (100 %) at the loss of specificity (87.5 %). Methylene blue dye alone can be successfully used for SLN identification in early oral cancers with a good accuracy and sensitivity. This method will be of use especially in resource limited countries and centres where nuclear medicine facilities are not widely available. However, it has to be validated by larger randomised multi institutional trials for wider applicability. Immunohistochemistry increases the sensitivity and negative predictive value of SLN but its applicability in real time decision making is limited. PMID:25419060

    Esophageal cancer with post-operative lymph node metastasis (LNM) compressing and infiltrating the trachea causing dyspnea is considered a serious complication. However, chemotherapy or radiotherapy are often ineffective methods for such patients. Approaches employing metallic expandable stents to relieve airway obstruction are extremely effective in advanced-stage cancer patients. The present study reports the use of metallic expandable stents as a treatment for tracheal stenosis. A total of 11 patients with tracheal stenosis due to LNM compressing and infiltrating the trachea were selected between November 2009 and January 2013. All the patients were diagnosed by computed tomography and presented with varying degrees of dyspnea. A total of 13 stents were placed in 11 patients, without significant intraoperative complications. Post-operatively, all patients presented with significant improvement in respiratory function. The Borg score was determined 1 day after stent application. The mean score of dyspnea declined significantly from 7.0 to 0.9 (P<0.01), the mean heart rate decreased from 128 to 86 bpm (P<0.01), the mean respiratory rate decreased from 34 to 23 breaths/min (P<0.01) and the mean oxygen saturation increased from 85 to 97% (P<0.01). Complications included coughing, hemorrhage, chest pain, retention of secretions, halitosis and tumor regrowth. It may be concluded that metallic expandable stent placement is an effective strategy to palliate malignant tracheal stenosis. PMID:24179541

It may be concluded that metallic expandable stent placement is an effective strategy to palliate malignant tracheal stenosis. PMID:24179541

    Sentinel lymph node biopsy is the gold standard to detect metastatic invasion from primary breast cancer. This method can help patients avoid full axillary chain dissection, thereby decreasing the risk of morbidity. We propose an alternative to the traditional isotopic method, to detect and map the sentinel lymph nodes. Indeed, Patent Blue V is the most widely used dye in clinical routine for the visual detection of sentinel lymph nodes. A Recent study has shown the possibility of increasing the fluorescence quantum yield of Patent Blue V, when it is bound to human serum albumin. In this study we present a preclinical fluorescence imaging system to detect sentinel lymph nodes labeled with this fluorescent tracer. The setup is composed of a black and white CCD camera and two laser sources. One excitation source with a laser emitting at 635 nm and a second laser at 785 nm to illuminate the region of interest. The prototype is operated via a laptop. Preliminary experiments permitted to determine the device sensitivity in the ?mol.L-1 range as regards the detection of PBV fluorescence signals. We also present a preclinical evaluation performed on Lewis rats, during which the fluorescence imaging setup detected the accumulation and fixation of the fluorescent dye on different nodes through the skin.

    A complete R0 resection is the standard treatment in patients with gallbladder cancer and the only potentially definitive curative therapy. Major hepatectomy, including right or extended right hepatectomy with extrahepatic bile duct resection, would be an option in patients with locally advanced gallbladder cancer, while morbidity and mortality rate are still high. Herein, we report a case of a locally advanced gallbladder cancer invading the right hepatic artery (RHA), common hepatic duct, and transverse colon. This patient was successfully treated with parenchymal sparing surgery without major hepatectomy and achieved R0 resection by means of extended cholecystectomy combined with resection of the transverse colon, extrahepatic bile duct, and RHA. Intrahepatic arterial flow was preserved without reconstruction of the RHA, and the postoperative course was favorable. Liver parenchymal sparing surgery might be an alternative procedure in patients with gallbladder cancer, to minimize the risk of severe morbidity, if R0 resection is possible. PMID:24912578

    Purpose: To investigate the prognostic impact of lymph node ratio (LNR) on survival in the patients with Stage III rectal cancer. Methods and Materials: We retrospectively reviewed the data of 421 consecutive patients who underwent total mesorectal excision followed by chemoradiotherapy for rectal cancer from 1996 to 2006. The 232 patients with positive lymph nodes (LNs) were divided into four groups according to LNR quartiles: LNR {<=}0.1 (n = 69), {<=}0.2 (n = 49), {<=}0.4 (n = 54), and >0.4 (n = 60). The association between LNR and survival was evaluated by the Kaplan-Meier method and multivariate analysis with covariates of prognostic significance in univariate analysis. Results: The median numbers of examined and positive LNs were 17 and 3, respectively, and the median LNR was 0.20 (range, 0.03-1). There was a strong correlation between the number of positive LNs and LNR (r = 0.724, p < 0.001). After a median follow-up of 53 months (range, 9-138 months), the actuarial overall survival and disease-free survival rates at 5 years were 69% and 56%, respectively. The 5-year survival rate decreased as LNR increased ({<=}0.1, 89%; {<=}0.2, 67%; {<=}0.4, 64%; >0.4, 50%; p < 0.001). Lymph node ratio was also a significant prognostic factor on Cox regression analysis ({<=}0.1, hazard ratio [HR] = 1; {<=}0.2, HR = 1.3, p = 0.623; {<=}0.4, HR = 2.4, p = 0.047; >0.4, HR = 3.7, p = 0.005). Lymph node ratio had a prognostic effect on overall survival in subgroups of patients with N1 (p = 0.032) and N2 (p = 0.034) tumors. Conclusion: Lymph node ratio was the most significant predictor of survival in the patients with Stage III rectal cancer who had undergone postoperative chemoradiation.

    Background: Sentinel lymph node (SLN) biopsy is increasingly becoming an alternative method for assessing axillary status in breast carcinoma patients. Intraoperative SLN evaluation can potentially select patients for immediate axillary clearance and spare most of them a second surgical procedure. Nevertheless,no standard protocol for intraoperative SLN evaluation has been developed. The aims of this study were to establish the reliability

    Preoperative radiation significantly decreases the number of retrieved lymph nodes (LNs) in rectal cancer, but little is known with respect to the prognostic significance of negative LN (NLN) counts under these circumstances. In this study, Surveillance, Epidemiology, and End Results Program (SEER)-registered ypIII stage rectal cancer patients, and patients from Fudan University Shanghai Cancer Center (FDSCC) were combined and analyzed. The results showed that the survival rate of patients with n (cutoff) or more NLNs increased gradually when n ranged from two to nine. After n reached 10 or greater, survival rates were approximately equivalent. Furthermore, the optimal cutoff value of 10 was validated as an independent prognostic factor in stage ypIIIB and ypIIIC patients by both univariate and multivariate analysis (P < 0.001); the number of NLNs could also stratify the prognosis of ypN(+) patients in more detail. Patients in the FDSCC set validated these findings and confirmed that NLN count was not decreased in the good tumor regression group relative to the poor tumor regression group. These results suggest that NLN count is an independent prognostic factor for ypIIIB and ypIIIC rectal cancer patients, and, together with the number of positive LNs, this will provide better prognostic information than the number of positive LNs alone.

  7. Contribution of SPECT/CT imaging to radioguided sentinel lymph node biopsy in breast cancer, melanoma, and other solid cancers: from "open and see" to "see and open".

    A few years ago SPECT/CT was successfully incorporated into the sentinel node (SN) procedure for breast cancer and melanoma. Important contributions of SPECT/CT in these two malignancies were the anatomical localization of SNs already visualized on planar images, the detection of additional SNs in aberrant basins, and the depiction of SNs in cases with no visualization on planar images. Recently, in a large series of melanoma patients the use of SPECT/CT was associated with the detection of more metastatic SNs and a higher rate of disease-free survival. Following the experiences in breast cancer and melanoma, SPECT/CT has been applied in oral cavity cancer as well as in urological and gynaecological malignancies. In the areas of lymphatic drainage of these malignancies (head and neck, pelvis, and upper abdomen) SPECT/CT appears to be essential to localize SNs, providing surgeons with helpful anatomical landmarks to plan SN biopsies. In gastrointestinal and lung malignancies SPECT/CT has only incidentally been used. With the improvement of the CT component in the second generation of SPECT/CT gamma cameras, nuclear physicians today can identify lymph nodes corresponding with the radioactive SNs. This is possible using a display of SPECT/CT similar to that of conventional tomography. Multiplanar reconstruction enables to correlate radioactive sentinel nodes seen on fused SPECT/CT with lymph nodes seen on CT, and the use of cross-reference lines allows the navigation between axial, coronal and sagittal views. This visual information is helpful for the intraoperative procedure and for post-excision assessment using portable devices. Fused SPECT/CT images may also be three-dimensionally displayed, improving anatomical SN localisation and recognition. This recent imaging improvement is leading to a new paradigm of "see and open" in contraposition to the former "open and see" in the SN procedure. The new mixed reality protocols which are able to transfer SPECT/CT to the operating room for surgical navigation will reinforce this "see and open" concept. However, a comprehensive interpretation of SPECT/CT together with lymphoscintigraphy is necessary to identify radioactive lymph nodes as sentinel nodes and classify them into different categories that are important for the intraoperative procedure.

    SKP2, an F-box protein constituting the substrate recognition subunit of the SCFSKP2 ubiquitin ligase complex, is implicated in ubiquitin-mediated degradation of the cyclin-dependent kinase inhibitor p27KIP1. Our earlier studies revealed SKP2 as a target gene within the 5p13 amplicon that is often seen in small-cell lung cancers. In the present study we examined amplification status and expression levels of SKP2 in non-small-cell lung cancer (NSCLC) and investigated its clinicopathological significance in this type of tumor because amplification of DNA at 5p13 is observed frequently in NSCLCs as well as in small-cell lung cancers. SKP2 exhibited amplification in 5 (20%) of 25 cell lines derived from NSCLC, and the transcript was overexpressed in 11 (44%) of the 25 lines. Moreover, expression of SKP2 was up-regulated significantly in 60 primary NSCLC tumors as compared to nontumorous lung tissues (P < 0.0001). Elevated expression of SKP2 correlated significantly with positive lymph node metastasis (P = 0.007), with stage II or higher of the international TNM classification (P = 0.014), with poor or moderate differentiation (P < 0.001), and with the presence of squamous cell carcinoma (P = 0.037). Reduction of SKP2 expression by transfection of an anti-sense oligonucleotide inhibited invasion and migration of NSCLC cells in culture. Our results suggest that SKP2 may be involved in progression of NSCLC, and that targeting this molecule could represent a promising therapeutic option. PMID:15215173

    Purpose: Survival in oral cavity squamous cell carcinoma (OSCC) depends heavily on locoregional control. In this prospective study, we sought to investigate whether preoperative maximum standardized uptake value of the neck lymph nodes (SUVnodal-max) may predict prognosis in OSCC patients. Methods and Materials: A total of 120 OSCC patients with pathologically positive lymph nodes were investigated. All subjects underwent a [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) scan within 2 weeks before radical surgery and neck dissection. All patients were followed up for at least 24 months after surgery or until death. Postoperative adjuvant therapy was performed in the presence of pathologic risk factors. Optimal cutoff values of SUVnodal-max were chosen based on 5-year disease-free survival (DFS), disease-specific survival (DSS), and overall survival (OS). Independent prognosticators were identified by Cox regression analysis. Results: The median follow-up for surviving patients was 41 months. The optimal cutoff value for SUVnodal-max was 5.7. Multivariate analyses identified the following independent predictors of poor outcome: SUVnodal-max {>=}5.7 for the 5-year neck cancer control rate, distant metastatic rate, DFS, DSS, and extracapsular spread (ECS) for the 5-year DSS and OS. Among ECS patients, the presence of a SUVnodal-max {>=}5.7 identified patients with the worst prognosis. Conclusion: A SUVnodal-max of 5.7, either alone or in combination with ECS, is an independent prognosticator for 5-year neck cancer control and survival rates in OSCC patients with pathologically positive lymph nodes.

    A 64-year-old woman noticed a lump of the right breast and consulted our outpatient clinic. She had undergone multiple excisional biopsies of fibroadenomas in both breasts and mastectomy for invasive ductal carcinoma (IDC) of the left breast. After completing 5 years of treatment with adjuvant tamoxifen, she had undergone screening with annual physical examinations and occasional computed tomography. She was declared recurrence-free 13 years after breast cancer surgery, although lumps were detected in the right breast, probably due to fibroadenomas. Mammography, ultrasonography, and magnetic resonance imaging revealed that the lump was irregularly shaped, 2 cm in diameter, and adjacent to a fibroadenoma with macrocalcification. Two axillary lymph nodes were enlarged and suggestive of metastasis. A core needle biopsy revealed IDC of the right breast. She underwent a right partial mastectomy with axillary lymph node dissection. The IDC was 2 cm in diameter, of nuclear grade 2, and adjacent to a 0.7-cm fibroadenoma with a macrocalcification. The margins of the IDC close to the fibroadenoma were clearly demarcated by the fibrous capsule of the fibroadenoma. Four axillary lymph nodes were positive for metastasis. In the present case the presence of fibroadenoma might have interfered with the early detection of the contralateral IDC. The history of multiple excisions of fibroadenomas and mastectomy for breast cancer suggests an increased risk of contralateral breast cancer for the patient's entire life; therefore, regular annual follow-up, such as physical examinations and mammography, is recommended.

    Recently, iatrogenic foreign-body granuloma has been increasingly reported. The asymptomatic presentation and confusing appearance of granuloma can lead to misdiagnosis of a secondary malignancy, especially for a patient with a corresponding past medical history. Sometimes, surgical treatment is unavoidable, and the diagnosis relies upon the pathologic result. Herein, we report an unusual case of a 43-year-old man who underwent a nephrectomy for renal cell carcinoma (clear cell type) 5 years ago. A secondary granuloma was identified behind the inferior vena cava in the retroperitoneum 6 months after the surgery, but the radiologists had failed to identify it throughout the 4 years of routine examination. Later on, the lesion was identified by positron emission tomography, which classified it as a highly 18F-fluorodeoxyglucose-avid lesion. Considering no visible foreign-bodies identified on images, the lesion was arguably diagnosed as a lymph node metastasis of renal cancer. Finally, it was confirmed as a foreign-body granuloma encasing surgical suture and adipose tissue by the pathological analysis. PMID:25429231

    AIM: To develop lymph node metastasis (LNM)-associated biomarkers for colorectal cancer (CRC) using quantitative proteome analysis. METHODS: Differences in protein expression between primary CRC with LNM (LNM CRC) and without LNM (non-LNM CRC) were assessed using methyl esterification stable isotope labeling coupled with 2D liquid chromatography followed by tandem mass spectrometry (2D-LC-MS/MS). The relationship to clinicopathological parameters and prognosis of candidate biomarkers was examined using an independent sample set. RESULTS: Forty-three proteins were found to be differentially expressed by at least 2.5-fold in two types of CRC. S100A4 was significantly upregulated in LNM CRC compared with non-LNM CRC, which was confirmed by Western blotting, immunohistochemistry and real-time quantitative polymerase chain reaction. Further immunohistochemistry on another 112 CRC cases showed that overexpression of S100A4 frequently existed in LNM CRC compared with non-LNM CRC (P < 0.001). Overexpression of S100A4 was significantly associated with LNM (P < 0.001), advanced TNM stage (P < 0.001), increased 5-year recurrence rate (P < 0.001) and decreased 5-year overall survival rate (P < 0.001). Univariate and multivariate analyses indicated that S100A4 expression was an independent prognostic factor for recurrence and survival of CRC patients (P < 0.05). CONCLUSION: S100A4 might serve as a powerful biomarker for LNM and a prognostic factor in CRC. PMID:21218086

    The aim of the present study was to investigate the expression of a number of angiogenic factors such as VEGF, VEGF-C, TGF-alpha and apoptosis in an attempt to relate these biological markers to TNM staging, lymph-node status and prognosis. Angiogenic factors and apoptosis were studied immunohistochemically in 72 gastric cancer cases. The search for micrometastases was performed with an immunohistochemical technique in 20 NO cases. Apoptosis determination was assessed with the TUNEL assay. The chi2 test according to Pearson was used for statistical analysis. The apoptotic index was related to both stage and prognosis: high expression cases showed an earlier stage (p < 0.02) and a better prognosis (p < 0.05). The determination of high neovessel density was related to poorer 5-year survival (p < 0.05). Only the expression of VEGF-C correlated inversely with prognosis (p < 0.05). The presence of micrometastases was unrelated to any of the biological markers studied. Our results partly confirm those reported in the literature. The present study revealed a number of biological markers that may be helpful for identifying particular subgroups of patients. More investigation with similar techniques in large prospective series is needed as a support to clinical practice. PMID:17966762

    We assessed the impact of internal mammary chain radiotherapy (IMC RT) to the radiation dose received by the heart in terms of heart dose-volume histogram (DVH). Thirty-six consecutive breast cancer patients presenting with indications for IMC RT were enrolled in a prospective study. The IMC was treated by a standard conformal RT technique (50 Gy). For each patient, a cardiac DVH was generated by taking into account the sole contribution of IMC RT. Cardiac HDV were compared according to breast cancer laterality and the type of previous surgical procedure, simple mastectomy or breast conservative therapy (BCT). The contribution of IMC RT to the heart dose was significantly greater for patients with left-sided versus right-sided tumors (13.8% and 12.8% for left-sided tumors versus 3.9% and 4.2% for right-sided tumors in the BCT group and the mastectomy group, respectively; p < 0.0001). There was no statistically significant difference in IMC contribution depending on the initial surgical procedure. IMC RT contributes to cardiac dose for both left-sided and right-sided breast cancers, although the relative contribution is greater in patients with left-sided tumors.

    The aim of the study was to identify a set of discriminating genes that could be used for the prediction of Lymph node (LN) metastasis in human colorectal cancer (CRC), and for this, we compared the whole genome profiles of two CRC cell lines (the primary cell line SW480 and its LN metastatic variant, SW620) and identified eight genes [S100 calcium-binding protein P; aldo-keto reductase family 1(AKR1), member B1 (aldose reductase; AKR1B1); AKR1, member C3 (AKR1C3); calponin 3, acidic; metastasis associated in colon cancer 1; hemoglobin, epsilon 1; trefoil factor 3; and FGGY carbohydrate kinase domain containing]. These genes were examined by quantitative RT-PCR in tissues and LNs in 14 CRC patients and 11 control patients. The level of AKR1C3 mRNA expression was significantly different between the Dukes' stage A, B, and C groups and the control group (p < 0.05, p < 0.001, and p < 0.001) and was also significantly different between Dukes' stage C and A or B groups (p < 0.05 and p < 0.001, respectively). The expression of CNN3 was significantly different between the Dukes' stage C and B or control groups (p < 0.001 and p < 0.01, respectively). There were significant correlations between the expression levels of AKR1C3 and CNN3. AKR1C3 and CNN3 expressions are more accurate and suitable markers for the diagnosis of LN metastasis than the other six genes examined in this study. PMID:24934327

    Purpose: To evaluate the outcome of external beam radiotherapy for abdominal lymph node (LN) metastases in patients with recurrent gastric cancer. Methods and Materials: The clinical data of 79 patients with abdominal LN metastases developing after curative resection of gastric tumor were retrospectively analyzed. Of the 79 patients, 37 received radiation (40-60 Gy in fractions of 2.0 Gy daily, five times weekly; termed the radiation group), and 42 received chemotherapy or supportive care (the nonradiation group). The Kaplan-Meier method was used to evaluate survival, and a Cox regression model was used to identify predictors of prognosis. Results: After radiation, complete response and partial response were observed in 29.7% and 54.1% of patients, respectively. Clinical symptoms were relieved in 19 of 21 patients (90.5%) after completing radiation. Median survival time was 11.4 months in the radiation group and 4.8 months in the nonradiation group. Overall survival for patients with and without radiation was 43.2% and 19.0% at 1 year and 27.6% and 4.1% at 2 years, respectively (p = 0.002). Multivariate analysis showed that the relative risk of death in the radiation group from the time of diagnosis of LN metastases was 0.253 (p < 0.001). The most common adverse effect of radiation was gastrointestinal toxicity, but it was mild in most patients. Conclusions: Abdominal LN metastases from gastric cancer are sensitive to radiation. Delivery of 50 Gy is effective as palliative treatment and may prolong overall survival.

    Purpose: To evaluate the therapeutic results and histopathological effects of treatment with thermochemoradiation therapy using superselective intra-arterial infusion via the superficial temporal and occipital arteries for N3 cervical lymph node metastases of advanced oral cancer. Methods and Materials: Between April 2005 and September 2010, 9 patients with N3 cervical lymph node metastases of oral squamous cell carcinoma underwent thermochemoradiation therapy using superselective intra-arterial infusion with docetaxel (DOC) and cisplatin (CDDP). Treatment consisted of hyperthermia (2-8 sessions), superselective intra-arterial infusions (DOC, total 40-60 mg/m{sup 2}; CDDP, total 100-150 mg/m{sup 2}) and daily concurrent radiation therapy (total, 40-60 Gy) for 4-6 weeks. Results: Six of 9 patients underwent neck dissection 5-8 weeks after treatment. In four of these 6 patients, all metastatic lymph nodes, including those at N3, were grade 3 (non-viable tumor cells present) or grade 4 (no tumor cells present) tumors, as classified by the system by Shimosato et al (Shimosato et al Jpn J Clin Oncol 1971;1:19-35). In 2 of these 6 patients, the metastatic lymph nodes were grade 2b (destruction of tumor structures with a small amount of residual viable tumor cells). The other 3 patients did not undergo neck dissection due to distant metastasis after completion of thermochemoradiation therapy (n=2) and refusal (n=1). The patient who refused neck dissection underwent biopsy of the N3 lymph node and primary sites and showed grade 3 cancer. During follow-up, 5 patients were alive without disease, and 4 patients died due to pulmonary metastasis (n=3) and noncancer-related causes (n=1). Five-year survival and locoregional control rates were 51% and 88%, respectively. Conclusions: Thermochemoradiation therapy using intra-arterial infusion provided good histopathologic effects and locoregional control rates in patients with N3 metastatic lymph nodes. However, patients with N3 metastatic lymph nodes experienced a high rate of distant metastases.

    Purpose: To evaluate the effect of postmastectomy radiotherapy (PMRT) in Stage II-III breast cancer patients with negative lymph nodes (pN0) after neoadjuvant chemotherapy (NAC). Patients and Materials: Of 1,054 breast cancer patients treated with NAC at our institution between 1990 and 2004, 134 had pN0 status after NAC and mastectomy. The demographic data, tumor characteristics, metastatic sites, and treatments were prospectively recorded. The effect of PMRT on locoregional recurrence-free survival and overall survival (OS) was evaluated by multivariate analysis, including known prognostic factors. Results: Of the 134 eligible patients, 78 (58.2%) received PMRT and 56 (41.8%) did not. At a median follow-up time of 91.4 months, the 5-year locoregional recurrence-free survival and OS rate was 96.2% and 88.3% with PMRT and 92.5% and 94.3% without PMRT, respectively (p = NS). The corresponding values at 10 years were 96.2% and 77.2% with PMRT and 86.8% and 87.7% without PMRT (p = NS). On multivariate analysis, PMRT had no effect on either locoregional recurrence-free survival (hazard ratio, 0.37; 95% confidence interval, 0.09-1.61; p = .18) or OS (hazard ratio, 2.06; 95% confidence interval, 0.71-6; p = .18). This remained true in the subgroups of patients with clinical Stage II or Stage III disease at diagnosis. A trend was seen toward poorer OS among patients who had not had a pathologic complete in-breast tumor response after NAC (hazard ratio, 6.65; 95% confidence interval, 0.82-54.12; p = .076). Conclusions: The results from the present retrospective study showed no increase in the risk of distant metastasis, locoregional recurrence, or death when PMRT was omitted in breast cancer patients with pN0 status after NAC and mastectomy. Whether the omission of PMRT is acceptable for these patients should be addressed prospectively.

    Objective We propose a new staging system for stage I endometrial cancer and compare its performance to the 1988 and 2009 International Federation of Gynecology and Obstetrics (FIGO) systems. Methods We analyzed patients with 1988 FIGO stage I endometrial cancer from January 1993 to August 2011. Low-grade carcinoma consisted of endometrioid grade 1 to grade 2 lesions. High-grade carcinoma consisted of endometrioid grade 3 or nonendometrioid carcinomas (serous, clear cell, and carcinosarcoma). The proposed system is as follows: IA Low-grade carcinoma with less than half myometrial invasion IA1 Negative nodes IA2 No nodes removed IB High-grade carcinoma with no myometrial invasion IB1 Negative nodes IB2 No nodes removed IC Low-grade carcinoma with half or greater myometrial invasion IC1 Negative nodes IC2 No nodes removed ID High-grade carcinoma with any myometrial invasion ID1 Negative nodes ID2 No nodes removed Results Data from 1843 patients were analyzed. When patients were restaged with our proposed system, the 5-year overall survival significantly differed (P < 0.001): IA1, 96.7%; IA2, 92.2%; IB1, 92.2%; IB2, 76.4%; IC1, 83.9%; IC2, 78.6%; ID1, 81.1%; and ID2, 68.8%. The bootstrap-corrected concordance probability estimate for the proposed system was 0.627 (95% confidence interval, 0.590–0.664) and was superior to the concordance probability estimate of 0.530 (95% confidence interval, 0.516–0.544) for the 2009 FIGO system. Conclusions By incorporating histological subtype, grade, myometrial invasion, and whether lymph nodes were removed, our proposed system for stage I endometrial cancer has a superior predictive ability over the 2009 FIGO staging system and provides a novel binary grading system (low-grade including endometrioid grade 1–2 lesions; high-grade carcinoma consisting of endometrioid grade 3 carcinomas and nonendometrioid carcinomas).

  4. Combined targeting of TGF-?1 and integrin ?3 impairs lymph node metastasis in a mouse model of non-small-cell lung cancer

    PubMed Central

    2014-01-01

    Background Transforming Growth Factor beta (TGF-?) acts as a tumor suppressor early in carcinogenesis but turns into tumor promoter in later disease stages. In fact, TGF-? is a known inducer of integrin expression by tumor cells which contributes to cancer metastatic spread and TGF-? inhibition has been shown to attenuate metastasis in mouse models. However, carcinoma cells often become refractory to TGF-?-mediated growth inhibition. Therefore identifying patients that may benefit from anti-TGF-? therapy requires careful selection. Methods We performed in vitro analysis of the effects of exposure to TGF-? in NSCLC cell chemotaxis and adhesion to lymphatic endothelial cells. We also studied in an orthotopic model of NSCLC the incidence of metastases to the lymph nodes after inhibition of TGF-? signaling, ?3 integrin expression or both. Results We offer evidences of increased ?3-integrin dependent NSCLC adhesion to lymphatic endothelium after TGF-? exposure. In vivo experiments show that targeting of TGF-? and ?3 integrin significantly reduces the incidence of lymph node metastasis. Even more, blockade of ?3 integrin expression in tumors that did not respond to TGF-? inhibition severely impaired the ability of the tumor to metastasize towards the lymph nodes. Conclusion These findings suggest that lung cancer tumors refractory to TGF-? monotherapy can be effectively treated using dual therapy that combines the inhibition of tumor cell adhesion to lymphatic vessels with stromal TGF-? inhibition.

    A retrospective study was conducted from a review of the medical records of patients with early-stage, invasive breast cancer who underwent surgical treatment and sentinel node biopsy with a radiotracer from January 2008 to August 2012 at a single institution (221 patients included). The patients were grouped according to the time of 99mTc Dextran-500 injection, which was preoperatively (with lymphoscintigraphy) (81 patients) or intraoperatively (140 patients). The purpose of the report is to compare the results of sentinel node biopsy of early-stage breast cancer patients who were subjected to intraoperative 99mTc Dextran-500 injections with the patients who received preoperative injections. The following parameters were analyzed: clinical tumor staging, histological and pathological results, size and number of tumor foci, peritumoral vascular invasion, number of lymph nodes removed, size of lymph node metastasis and hormone receptor expression.There were no differences in sentinel lymph node localization whether 99mTc Dextran-500 was injected preoperatively or intraoperatively.

    A 50-year-old patient had an early biochemical recurrence after radical prostatectomy and androgen deprivation therapy and castration. An anti-1-amino-3-[¹?F] fluorocyclobutane-1-carboxylic acid positron emission tomography/computed tomography scan showed a single pelvic lymph node metastasis. The patient was given volume-modulated arc therapy with a cumulative dose of 50 Gy for the volume with pelvic lymph nodes and 78 Gy to the boost volume for the lymph node metastasis. He experienced only a transitory mild toxicity from the rectum and the urinary bladder and had a partial remission for 16 months. PMID:24158080

    The management of the lateral neck in metastatic differentiated thyroid cancer (DTC) varies widely. Most groups advocate dissection of nodal levels II-IV but many perform a more extensive dissection. We aimed to asses whether there was any evidence for a modified radical neck dissection over a selective neck dissection by looking at the extent to which DTC metastases to levels I and V. We performed a review of the current literature including adult and paediatric patients who underwent a lateral neck dissection for metastatic DTC. The primary endpoint was histological confirmation of metastases in nodal levels I and V. 650 abstracts were identified and reviewed. 23 papers were included in the study. The incidence of level V metastases during routine level V dissection in patients with DTC is 20 % and the incidence of level I metastases during routine level I dissection in patients with DTC is 8 %. Histologically proven metastases were found in 22.5 % of level V neck dissection of which 2.5 % were pre-operatively suspected of metastases. 20 % had histologically proven metastases to level I of which 12 % were pre-operatively suspected of metastases. Our study has shown a 20 % incidence of level V metastases in the N+ neck suggesting that level V should be part of a planned neck dissection. Evidence is lacking for routine dissection of level I. A future prospective study is required to asses the question of risk factors for lateral nodal metastases, recurrence and survival. PMID:23519682

    Objective To prospectively define the prevalence of lymph node metastasis (LNM) in at risk endometrial cancer (EC). Methods From 2004-2008, frozen section based Mayo Criteria prospectively identified patients “not at-risk” of LNM (30% EC population; grade I/II, <50% myometrial invasion and tumor diameter ?2cm) where lymphadenectomy was not recommended. The remaining 70% EC cohort was considered “at-risk” of LNM; where a systematic pelvic and infrarenal paraaortic lymphadenectomy was recommended. Patients were prospectively followed. The area between renal vein and inferior mesenteric artery (IMA) was labeled as high paraaortic area. For calculating the prevalence of LNM in high paraaortic area, the denominator was the population with known anatomic location of nodal tissue in relation to the IMA. Results Of the 742 patients, 514 were at risk; of which 89% underwent recommended lymphadenectomy. A mean (± standard deviation) of 36 (±14) pelvic and 18 (±9) paraaortic nodes were harvested. The prevalence of pelvic and paraaortic LNM was 17% and 12%, respectively. In presence of pelvic LNM, 51% had paraaortic LNM. In absence of pelvic LNM, 3% had paraaortic LNM; of which 67% were located exclusively in high paraaortic area. Among patients with paraaortic LNM, 88% had high paraaortic LNM; and 35% had only high paraaortic LNM. The cases of paraaortic LNM with negative pelvic nodes seemed to cluster in moderate to high grade endometrioid EC with ?50% myometrial invasion. Conclusion We present reference data for the prevalence of LNM in at-risk EC patients to guide lymphadenectomy decisions for clinical and research purposes. PMID:24120926

    Profiling studies have identified specific microRNA (miRNA) signatures in malignant tumors including breast cancer. Our aim was to assess intratumoral heterogeneity in miRNA expression levels within primary breast cancers and between axillary lymph node metastases from the same patient. Specimens of 16 primary breast cancers were sampled in 8-10 distinct locations including the peripheral, intermediate, and central tumor zones, as well as two to five axillary lymph node metastases (n = 9). Total RNA was extracted from 132 paraffin-embedded samples, and the expression of miR-10b, miR-210, miR-31, and miR-335 was assessed as well as the reproducibility of RNA extraction and miRNA analysis by quantitative RT-PCR. Considerable intratumoral heterogeneity existed for all four miRNAs within primary breast cancers (CV 40%). No significant differences within (CV 34%) or between different tumor zones (CV 33%) were found. A similar variation in miRNA expression was observed between corresponding lymph node metastases (mean CV 40%). In comparison, the variation among different patients showed a CV of 80% for primary tumors and 103% for lymph node metastases. Both miRNA extraction procedures and quantitative RT-PCR showed high reproducibility (CV ? 2%). Thus, the intratumoral heterogeneity of miRNA expression in breast cancers can lead to significant sampling bias. Assessment of breast cancer miRNA profiles may require sampling at several different tumor locations and of several tumor-involved lymph nodes when deriving miRNA expression profiles of metastases.

    With regard to laparoscopic and robotic abdominoperineal resection (APR) for primary rectal malignancies, limited data have been published in the literature. Single-incision laparoscopic surgery (SLS) has been successfully introduced for treating colorectal cancer. Here we describe our experience of APR with SLS plus one port (SLS + 1) for treating advanced rectal cancer. A 65-year-old man underwent the procedure, which involved a 35-mm incision in the left side of the umbilicus for the insertion of a single multichannel port as well as the insertion of a 5-mm port into the right lower quadrant. The sigmoid colon and rectum were mobilized from the pelvic floor using a medial and lateral approach. After the rectum with the mesorectum was completely mobilized according to the total mesorectal excision, the sigmoid colon was intracorporeally transected. The specimen was removed through the perineal wound. Terminal colostomy was fashioned at the left lower trocar site. Lateral pelvic lymph node dissection was bilaterally performed. There were no perioperative complications. The total operating time was 592 minutes, and the estimated blood loss was 180 mL. To our knowledge, this is the first reported case of SLS + 1 APR with lateral pelvic lymph node dissection for treating rectal cancer. We conclude that SLS + 1 APR is a technically promising alternative method for treating selected patients with advanced rectal cancer. PMID:25594635

    Introduction Lymph nodes are one of the main sites where an effective immune response develops. Normally, axillary nodes are the first place where breast cancer produces metastases. Several studies have demonstrated the importance of immune cells, especially dendritic cells, in the evolution of breast cancer. The goal of the project is to identify differences in the patterns of immune infiltrates, with particular emphasis on dendritic cells, in tumour and axillary node biopsies between patients with and without metastases in the axillary nodes at the time of diagnosis. It is expected that these differences will be able to explain differences in survival, relapse and clinicopathological variables between the two groups. Methods and analysis The study will involve 100 patients diagnosed with invasive breast cancer between 2000 and 2007, 50% of whom have metastases in the axillary lymph node at diagnosis. In selected patients, two cylinders from biopsies of representative areas of tumour and axillary nodes (with and without metastasis) will be selected and organised in tissue microarrays. Samples will be stained using immunohistochemical techniques for different markers of immune response and dendritic cells. Two images of each cylinder will be captured under standardised conditions for each marker. Each marker will be quantified automatically by digital image procedures using Image-Pro Plus and Image-J software. Associations of survival, relapse and other clinicopathological variables with the automatically quantified levels of immune infiltrates in patients with and without axillary node metastasis will be sought. Ethics and dissemination The present project has been approved by the Clinical Research Ethics Committee of the Hospital Universitari Joan XXIII (Ref: 22p/2011). Those patients whose biopsies and clinical data are to be used will give their signed informed consent. Results will be published in peer-reviewed journals. PMID:25091015

    Purpose: To investigate the potential effect of using {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in the initial assessment of patients with clinical Stage II or III breast cancer. Methods and Materials: During 14 consecutive months, 39 patients (40 tumors) who presented with Stage II or III breast cancer on the basis of a routine extension assessment were prospectively included in this study. PET/CT was performed in addition to the initial assessment. Results: In 3 cases, PET/CT showed extra-axillary lymph node involvement that had not been demonstrated with conventional techniques. Two of these patients had hypermetabolic lymph nodes in the subpectoral and infraclavicular regions, and the third had a hypermetabolic internal mammary node. PET/CT showed distant uptake in 4 women. Of these 4 women, 1 had pleural involvement and 3 had bone metastasis. Overall, of the 39 women, the PET/CT results modified the initial stage in 7 (18%). The modified staging altered the treatment plan for 5 patients (13%). It led to radiotherapy in 4 patients (bone metastasis, pleural lesion, subpectoral lymph nodes, and internal mammary nodes) and excision of, and radiotherapy to, the infraclavicular lymph nodes in 1 patient. Conclusions: PET/CT can provide information on extra-axillary lymph node involvement and can uncover occult distant metastases in a significant percentage of patients. Therefore, initial PET/CT could enable better treatment planning for patients with Stage II and III breast cancer.

    Background: Central compartment lymph node metastases in papillary thyroid carcinoma (PTC) are difficult to detect preoperatively, and the role of routine or prophylactic central compartment lymph node dissection (CLND) in managing PTC remains controversial. The aim of this project was to create a nomogram able to predict the occurrence of central compartment lymph node metastasis using readily available preoperative clinical characteristics. Methods: Records from patients undergoing total thyroidectomy and lymph node dissection for PTC in the period 1968–2012 were analyzed. Nodal status was based on results of serial hematoxylin and eosin (H&E) examination. Age, sex, tumor size, tumor site, and multifocality were included in a multivariable logistic regression model to predict lymph node metastasis. A coefficient-based nomogram was developed and validated using an external patient cohort. Results: The study population included 914 patients (80% females) with an average central compartment nodal yield of eight per patient. Central compartment lymph node metastases were present in 390 patients (42.7%). The variables with the strongest predictive value were age (p<0.001), male sex (p<0.001), increasing tumor size (p<0.001), and tumor multifocality (p<0.05). The nomogram had good discrimination with a concordance index of 76.4% [95% confidence interval 73.3–79.4], supported by an external validation point estimate of 61.5% [95% confidence interval 49.5–73.6]. An online calculator and smartphone application were developed for point of care use. Conclusions: A validated nomogram utilizing readily available preoperative variables has been developed to give a predicted probability of central lymph node metastases in patients presenting with PTC. This nomogram may help guide surgical decision making in PTC. PMID:24083952

    Sentinel lymph node (SLN) biopsy is a part of the staging procedure in breast cancer patients. Intraoperative molecular analysis for SLN metastases using the one-step nucleic acid amplification (OSNA) method based on reverse-transcription loop-mediated amplification (RT-LAMP) has already been validated in breast cancer. In this study, we compare the intraoperative OSNA method to our routine histological investigation. To evaluate the performance of OSNA in comparison to histology, analysis of 74 SLN from 60 breast cancer patients was conducted with both methods. Of the 22 histologically positive samples, 14 were attributed to macrometastases (++) in the OSNA-CK19 assay and 8 to micrometastases (+). Two samples negative in histopathology were positive in the OSNA method (micrometastases +). Our results show that OSNA is an excellent method for the detection of metastases in lymph nodes and can be applied as an intraoperative diagnostic approach. Intraoperative molecular analysis for SLN metastases using the OSNA method reduces the number of admission days and duration of surgery. To our knowledge this is the first study referring to Polish women. PMID:23900867

    In October 2008, a 66-year-old male patient underwent resection of the right half of the colon for ascending colon cancer. Histopathological examination revealed a tumor classification of tub2, pSE, ly1, v0, PM0, DM0, RM0, pN1(2/23), H0 , P0 , Stage III a. The patient was treated with uracil/tegafur plus Leucovorin(UFT/LV)chemotherapy after surgery. However, he developed Grade 2 liver dysfunction after completion of 1 course, so UFT/LV was discontinued. In June 2009, a rise in the carcinoembryonic antigen(CEA)level was observed, and computed tomography(CT)and positron emission tomography with 2-[fluorine-18]fluoro-2-deoxy-D-glucose(FDG-PET)showed a single enlarged lymph node, 2 cm in diameter, located around the aorta. We informed the patient of the therapeutic effect of anticancer drug treatment and surgery, risk of adverse events, and other management methods, and UFT/LV chemotherapy was selected as treatment. After 3 courses, the lymph node had completely disappeared, and UFT/LV was discontinued in April 2011, as there was no sign of recurrence. The patient remains alive and well. We report a case of para-aortic lymph node metastasis after surgery, treated with UFT/LV, which led to a complete response without major adverse events. PMID:24743211

    AIM: To investigate the early metastasis-associated proteins in sentinel lymph node micrometastasis (SLNMM) of colorectal cancer (CRC) through comparative proteome. METHODS: Hydrophobic protein samples were extracted from individual-matched normal lymph nodes (NLN) and SLNMM of CRC. Differentially expressed protein spots were detected by two-dimensional electrophoresis and image analysis, and subsequently identified by matrix assisted laser desorption/ionization-time of flight mass spectrometry-mass spectrometry and Western blotting, respectively. RESULTS: Forty proteins were differentially expressed in NLN and SLNMM, and 4 metastasis-concerned proteins highly expressed in SLNMM were identified to be hnRNP A1, Ezrin, tubulin ?-2C and Annexin A1. Further immunohistochemistry staining of these four proteins showed their clinicopathological characteristics in lymph node metastasis of CRC. CONCLUSION: Variations of hydrophobic protein expression in NLN and SLNMM of CRC and increased expression of hnRNP A1, Ezrin, tubulin ?-2C and Annexin A1 in SLNMM suggest a significantly elevated early CRC metastasis.

    Patients with invasive squamous cell carcinoma of the penis and tumor involvement of the inguinal nodes are at risk for pelvic lymph node metastases. When this spread occurs, the chance for patient survival is limited. Because the sensitivity of CT in detecting pelvic lymph node metastases is low, open surgical pelvic lymphadenectomy is frequently performed. We have utilized laparoscopic pelvic lymphadenectomy as a minimally invasive alternative to this open approach in three patients with Stage T3 (UICC staging system) squamous cell carcinoma of the penis who had persistent inguinal adenopathy after a standard course of postpenectomy antiobiotic therapy. There were no intraoperative or postoperative complications, and all patients were discharged within 24 hours after surgery. The mean number of nodes removed was eight, and all specimens were free of tumor. Laparoscopic pelvic lymphadenectomy should be considered in patients with persistent inguinal adenopathy after antibiotic therapy before proceeding with inguinal lymph node dissection. PMID:7858625

    Purpose: To determine the clinical value of two novel molecular imaging techniques: {sup 11}C-choline positron emission tomography (PET)/computed tomography (CT) and ferumoxtran-10 enhanced magnetic resonance imaging (magnetic resonance lymphography [MRL]) for lymph node (LN) treatment in prostate cancer (PCa) patients. Therefore, we evaluated the ability of PET/CT and MRL to assess the number, size, and location of LN metastases in patients with primary or recurrent PCa. Methods and Materials: A total of 29 patients underwent MRL and PET/CT for LN evaluation. The MRL and PET/CT data were analyzed independently. The number, size, and location of the LN metastases were determined. The location was described as within or outside the standard clinical target volume for elective pelvic irradiation as defined by the Radiation Therapy Oncology Group. Subsequently, the results from MRL and PET/CT were compared. Results: Of the 738 LNs visible on MRL, 151 were positive in 23 of 29 patients. Of the 132 LNs visible on PET/CT, 34 were positive in 13 of 29 patients. MRL detected significantly more positive LNs (p < 0.001) in more patients than PET/CT (p = 0.002). The mean diameter of the detected suspicious LNs on MRL was significantly smaller than those detected by PET/CT, 4.9 mm and 8.4 mm, respectively (p < 0.0001). In 14 (61%) of 23 patients, suspicious LNs were found outside the clinical target volume with MRL and in 4 (31%) of 13 patients with PET/CT. Conclusion: In patients with PCa, both molecular imaging techniques, MRL and {sup 11}C-choline PET/CT, can detect LNs suspicious for metastasis, irrespective of the existing size and shape criteria for CT and conventional magnetic resonance imaging. On MRL and PET/CT, 61% and 31% of the suspicious LNs were located outside the conventional clinical target volume. Therefore, these techniques could help to individualize treatment selection and enable image-guided radiotherapy for patients with PCa LN metastases.

    Carcinoma of the penis is rare, and the prognosis of penile cancer with inguinal metastases is extremely poor. Standard chemotherapy for advanced penile cancer has not been established because of its rarity. A case of penile cancer with inguinal metastases that responded well to neoadjuvant chemotherapy with paclitaxel, ifosfamide and cisplatin (TIP) is described. A 55-year-old Japanese male visited our hospital for a penile tumor and fixed, 4 cm, right inguinal lymph nodes. Computed tomography and 18F-FDG-PET imaging showed not only right but also left inguinal lymphadenopathy. Penile cancer (clinical stage T3N3M0, 7th edition TNM classification) was diagnosed, and partial penectomy and right inguinal biopsy were performed. The pathological examination revealed squamous cell carcinoma of the penis with right inguinal lymph node metastasis. The inguinal metastases were judged to be unsuitable for radical resection ; and, paclitaxel 60 mg/m2 (day 1), ifosfamide 1,200 mg/m2 (days 1-3), and cisplatin 60 mg/m2 (days 1-3) were given at 3-week intervals as neoadjuvant chemotherapy. After 4 courses of chemotherapy, the inguinal metastases were markedly reduced. He had neutropenia (grade 3) during each course and peripheral neuropathy after 2 courses, but there were no severe complications. The patient underwent bilateral inguinal and pelvic lymphadenectomy after neoadjuvant chemotherapy. Pathological examination revealed no viable cells in the resected specimens. The patient remains alive and well with no evidence of recurrence 8 months after this radical treatment. TIP chemotherapy appears to be effective for advanced penile cancer. PMID:25656018

    As part of a detailed study of prognostic factors in breast cancer, we have analyzed the ten year survival rates of 524 patients with primary invasive carcinomas 2.0 cm or less in diameter (T1). This report describes the subset of 142 patients (27%) who had metastases only in axillary lymph nodes (T1N1M0). All the patients were treated initially by at least a modified radical mastectomy. Factors associated with a significantly poorer prognosis were: axillary lymph node metastases suspected on clinical examination; perimenopausal menstrual status at diagnosis; tumor larger than 1.0 cm; prominent lymphoid reaction; infiltrating duct or lobular rather than medullary, colloid and tubular carcinoma; and blood vessel invasion. When compared with those patients with negative nodes (T1N0M0), the patients with one or more lymph node metastases had a significantly poorer prognosis. Generally, survival rates tended to diminish as the number of involved lymph nodes increased. In this respect, comparison of patients with one-three and four or more nodal metastases provided a significant discrimination of prognostic groups in the entire series. However, for patients with disease limited to Level I, the same discrimination was obtained comparing those with one-two and three or more positive nodes. In the subset with a single lymph node metastasis, the size of the metastasis (micro or less than or equal to 2 mm vs macro or greater than 2 mm) was not significantly related to prognosis. Lymph node metastases were significantly less frequent among tumors smaller than 1 cm and special tumor types (medullary, colloid, lobular and tubular). However, no factor proved to be a reliable predictor of the presence of axillary metastases for the single largest group consisting of patients with infiltrating duct carcinoma 1-2 cm in diameter.

    Purpose: Neoadjuvant chemotherapy (NAC) generally induces significant changes in the pathologic extent of disease. This potential down-staging challenges the standard indications of adjuvant radiation therapy. We assessed the utility of lymph node irradiation (LNI) in breast cancer (BC) patients with pathologic N0 status (pN0) after NAC and breast-conserving surgery (BCS). Methods and Materials: Among 1,054 BC patients treated with NAC in our institution between 1990 and 2004, 248 patients with clinical N0 or N1 to N2 lymph node status at diagnosis had pN0 status after NAC and BCS. Cox regression analysis was used to identify factors influencing locoregional recurrence-free survival (LRR-FS), disease-free survival (DFS), and overall survival (OS). Results: All 248 patients underwent breast irradiation, and 158 patients (63.7%) also received LNI. With a median follow-up of 88 months, the 5-year LRR-FS and OS rates were respectively 89.4% and 88.7% with LNI and 86.2% and 92% without LNI (no significant difference). Survival was poorer among patients who did not have a pathologic complete primary tumor response (hazard ratio, 3.05; 95% confidence interval, 1.17-7.99) and in patients with N1 to N2 clinical status at diagnosis (hazard ratio = 2.24; 95% confidence interval, 1.15-4.36). LNI did not significantly affect survival. Conclusions: Relative to combined breast and local lymph node irradiation, isolated breast irradiation does not appear to be associated with a higher risk of locoregional relapse or death among cN0 to cN2 breast cancer patients with pN0 status after NAC. These results need to be confirmed in a prospective study.

    A 48-year-old Japanese woman was found to have local recurrence of breast cancer in the chest wall following neoadjuvant chemotherapy, total mastectomy with axillary lymphadenectomy, postoperative radiation therapy to the chest wall, and adjuvant systemic therapy using trastuzumab. As a third line of treatment after recurrence, bevacizumab with paclitaxel was initiated for several metastatic lesions on the skin of the chest wall, left internal costal lymph nodes, and right axillary lymph nodes. The wound on the chest wall continued to expand in diameter and depth after the third course of bevacizumab with paclitaxel until the rib was exposed. After stopping the bevacizumab, granulation tissue expanded and by 3 months, had covered the bottom of the ulcer. The patient died soon thereafter, despite systemic chemotherapy with eribulin; however, there was no further bleeding from the ulcer on the chest wall or the exposed ribs. PMID:24831658

    Purpose: To compare chemotherapy alone with chemoradiation therapy in stage III-IV(M0) gastric cancer treated with R0 gastrectomy and D2 lymph node dissection. Methods and Materials: The chemotherapy arm received 5 cycles of fluorouracil and leucovorin (FL), and the chemoradiation therapy arm received 1 cycle of FL, then radiation therapy of 45 Gy concurrently with 2 cycles of FL, followed by 2 cycles of FL. Intent-to-treat analysis and per-protocol analyses were performed. Results: Between May 6, 2002 and June 29, 2006, a total of 90 patients were enrolled. Forty-four were randomly assigned to the chemotherapy arm and 46 to the chemoradiation therapy arm. Treatment was completed as planned by 93.2% of patients in the chemotherapy arm and 87.0% in the chemoradiation therapy arm. Overall intent-to-treat analysis showed that addition of radiation therapy to chemotherapy significantly improved locoregional recurrence-free survival (LRRFS) but not disease-free survival. In subgroup analysis for stage III, chemoradiation therapy significantly prolonged the 5-year LRRFS and disease-free survival rates compared with chemotherapy (93.2% vs 66.8%, P=.014; 73.5% vs 54.6%, P=.056, respectively). Conclusions: Addition of radiation therapy to chemotherapy could improve the LRRFS in stage III gastric cancer treated with R0 gastrectomy and D2 lymph node dissection.

    Forkhead box protein 3 (FOXP3) regulatory T cells (Tregs) are important in the maintenance of tumor immunity tolerance. Myeloid dendritic cells (mDCs) are antigen-presenting cells (APCs) specialized to initiate and regulate immunity. Tregs and mDCs are suspected of influencing the interaction between the tumor and immune system, and thus the course of tumors. However, the implication and interaction of their concurrent infitration in colorectal cancer (CRC) remain unknown. The aim of this study was to determine FOXP3+ Tregs and CD11c+ mDCs infiltration in CRC and tumor-draining lymph node (TDLN) and to explore the clinical and pathological implication of suppressor and effector immune cell subsets. Immunohistochemical assay was conducted to assess FOXP3+ Tregs and CD11c+ mDCs infiltration in tumor tissue and in metastasis-free TDLN (mfTDLN) and metastatic TDLN (mTDLN). The results showed that FOXP3+ Tregs and CD11c+ mDCs infiltration was higher in tumor tissue compared to adjacent normal mucosa (P<0.001). FOXP3+ Tregs infiltration was associated with advanced tumor-node-metastasis (TNM) stage and lymph node metastasis (P<0.001 and P<0.001, for TNM stage and lymph node metastasis, respectively), whereas less CD11c+ mDCs infiltration of tumor in situ was associated with deeper tumor invasion, advanced TNM stages and lymph node metastasis (P<0.05, P<0.001 and P<0.001, for tumor invasion depth, TNM stages and lymph node metastasis, respectively). Compared to mfTDLN, mTDLN was significantly enriched in FOXP3+ Tregs (P<0.001) and reduced in CD11c+ mDCs (P<0.001). The statistical analysis demonstrated no significant correlations in Tregs and mDCs infiltration. These results suggest that more FOXP3+ Tregs and less CD11c+ mDCs infiltration have stronger prognostic significance in CRC. The presence of tumor cells in mTDLN may contribute to a tolerogenic milieu and facilitate the survival of metastatic tumor cells. PMID:24648920

  7. Regulation of protumorigenic pathways by Insulin like growth factor binding protein2 and its association along with ?-catenin in breast cancer lymph node metastasis

    PubMed Central

    2013-01-01

    Background Insulin like growth factor binding proteins modulate the mitogenic and pro survival effects of IGF. Elevated expression of IGFBP2 is associated with progression of tumors that include prostate, ovarian, glioma among others. Though implicated in the progression of breast cancer, the molecular mechanisms involved in IGFBP2 actions are not well defined. This study investigates the molecular targets and biological pathways targeted by IGFBP2 in breast cancer. Methods Transcriptome analysis of breast tumor cells (BT474) with stable knockdown of IGFBP2 and breast tumors having differential expression of IGFBP2 by immunohistochemistry was performed using microarray. Differential gene expression was established using R-Bioconductor package. For validation, gene expression was determined by qPCR. Inhibitors of IGF1R and integrin pathway were utilized to study the mechanism of regulation of ?-catenin. Immunohistochemical and immunocytochemical staining was performed on breast tumors and experimental cells, respectively for ?-catenin and IGFBP2 expression. Results Knockdown of IGFBP2 resulted in differential expression of 2067 up regulated and 2002 down regulated genes in breast cancer cells. Down regulated genes principally belong to cell cycle, DNA replication, repair, p53 signaling, oxidative phosphorylation, Wnt signaling. Whole genome expression analysis of breast tumors with or without IGFBP2 expression indicated changes in genes belonging to Focal adhesion, Map kinase and Wnt signaling pathways. Interestingly, IGFBP2 knockdown clones showed reduced expression of ?- catenin compared to control cells which was restored upon IGFBP2 re-expression. The regulation of ?-catenin by IGFBP2 was found to be IGF1R and integrin pathway dependent. Furthermore, IGFBP2 and ?-catenin are co-ordinately overexpressed in breast tumors and correlate with lymph node metastasis. Conclusion This study highlights regulation of ?-catenin by IGFBP2 in breast cancer cells and most importantly, combined expression of IGFBP2 and ?-catenin is associated with lymph node metastasis of breast tumors.

    BACKGROUND: We studied potential risk factors for lymphedema in a contemporary population of older breast cancer patients. METHODS: Telephone surveys were conducted among women (65-89 years) identified from Medicare claims as having initial breast cancer surgery in 2003. Lymphedema was classified by self-report. Surgery and pathology information was obtained from Medicare claims and the state cancer registries. RESULTS: Of 1,338 patients treated by 707 surgeons, 24% underwent sentinel lymph node biopsy (SLNB) and 57% axillary lymph node dissection (ALND). At a median of 48 months postoperatively, 193 (14.4%) had lymphedema. Lymphedema developed in 7% of the 319 patients who underwent SLNB and 21% of the 759 patients who underwent ALND. When controlling for patient age, tumor size, type of breast cancer, type of breast and axillary surgery, receipt of radiation, chemotherapy, and hormonal therapy, and surgeon case volume, the independent predictors of lymphedema were the removal of more than five lymph nodes (OR 4.68-5.61, 95% CI: 1.36-19.74 for 6-15 nodes; OR 10.50, 95% CI 2.88-38.32 for > 15 nodes) and the presence of lymph node metastases (OR 1.98, 95% CI 1.21-3.24). CONCLUSIONS: Four years postoperatively, 14% of a contemporary, population-based cohort of elderly breast cancer survivors have self-reported lymphedema. In this group of predominately community-based surgeons, the number of lymph nodes removed is more predictive of lymphedema rather than whether SLNB or ALND was performed. As more women with breast cancer undergo only SLNB, it is essential that they still be counseled on their risk for lymphedema. PMID:19194754

    Purpose: To determine whether patients with 1, 2, or 3 positive lymph nodes (LNs) have similar survival outcomes. Methods and Materials: We analyzed the Surveillance, Epidemiology, and End Results registry of breast cancer patients diagnosed between 1990 and 2003. We identified 10,415 women with T1-2N1M0 breast cancer who were treated with mastectomy with no adjuvant radiation, with at least 10 LNs examined and 6 months of follow-up. The Kaplan-Meier method and log–rank test were used for survival analysis. Multivariate analysis was performed using the Cox proportional hazard model. Results: Median follow-up was 92 months. Ten-year overall survival (OS) and cause-specific survival (CSS) were progressively worse with increasing number of positive LNs. Survival rates were 70%, 64%, and 60% (OS), and 82%, 76%, and 72% (CSS) for 1, 2, and 3 positive LNs, respectively. Pairwise log–rank test P values were <.001 (1 vs 2 positive LNs), <.001 (1 vs 3 positive LNs), and .002 (2 vs 3 positive LNs). Multivariate analysis showed that number of positive LNs was a significant predictor of OS and CSS. Hazard ratios increased with the number of positive LNs. In addition, age, primary tumor size, grade, estrogen receptor and progesterone receptor status, race, and year of diagnosis were significant prognostic factors. Conclusions: Our study suggests that patients with 1, 2, and 3 positive LNs have distinct survival outcomes, with increasing number of positive LNs associated with worse OS and CSS. The conventional grouping of 1-3 positive LNs needs to be reconsidered.

    Rheumatoid arthritis (RA) is a chronic autoimmune disease with episodic flares in affected joints, whose etiology is largely unknown. Recent studies in mice demonstrated alterations in lymphatics from affected joints precede flares. Thus, we aimed to develop novel methods for measuring lymph node pressure and lymph viscosity in limbs of mice. Pressure measurements were performed by inserting a glass micropipette connected to a pressure transducer into popliteal lymph nodes (PLN) or axillary lymph nodes (ALN) of mice and determined that the lymphatic pressures were 9 and 12 cm of water, respectively. We are also developing methods for measuring lymph viscosity in lymphatic vessels afferent to PLN, which can be measured by multi-photon fluorescence recovery after photobleaching (MP-FRAP) of FITC-BSA injected into the hind footpad. These results demonstrate the potential of lymph node pressure and lymph viscosity measurements, and warrant future studies to test these outcomes as biomarkers of arthritic flare. PMID:22172039

    Purpose: To assess how neoadjuvant chemoradiation regimens modulate the immune system state in tumor-draining lymph nodes (TDLN), in the setting of advanced cervical cancer. Methods and Materials: Tumor-draining lymph nodes of patients undergoing chemotherapy only (nonirradiated, NI-TDLN) and chemoradiation with lower-dose (39.6 Gy, LD-TDLN) and higher-dose radiation (50 Gy, HD-TDLN) were analyzed by multicolor flow cytometry. Results: Enlarging our previous data, LD-TDLN showed features overall indicative of an enhanced antitumor response as compared with NI-TDLN, namely a significant Th1 and Tc1 polarization and a lower amount of the potent CD4{sup +}Foxp3{sup +}CD25{sup high} regulatory T cell (Treg) subset identified by neuropilin-1 expression. Conversely, compared with NI-TDLN, HD-TDLN showed features overall indicative of an impaired antitumor response, namely a significantly inverted CD4/CD8 cell ratio, a higher Nrp1{sup +}Treg frequency, and a higher frequency of CCR4{sup +}Treg, a Treg subset facilitated in migrating out from TDLN to suppress the immune response against distant cancer cells. Moreover, the Th1 and Tc1 polarization induced by LD radiation was lost, and there was an unfavorable tolerogenic/immunogenic dendritic cell ratio compared with LD-TDLN. Conclusions: Even minor differences in radiation dose in neoadjuvant regimens for locally advanced cervical cancer are crucial for determining the balance between a tolerogenic and an efficacious antitumor immune response in TDLN. Because most of the anticancer immune response takes place in TDLN, the present findings also emphasize the importance of chemoradiation protocols in the context of immunotherapeutic trials.

Methods and Materials: A total of 699 BC patients with pN0 status after MRM, treated between 2001 and 2008, were identified from a prospective database in a single institution. Tumors were classified by intrinsic molecular subtype as luminal A or B, HER2+, and triple-negative (TN) using estrogen, progesterone, and HER2 receptors. Multivariate Cox analysis was used to determine the risk of LRR associated with intrinsic subtypes and Ki67 expression, adjusting for known prognostic factors. Results: At a median follow-up of 56 months, 17 patients developed LRR. Five-year LRR-free survival and overall survival in the entire population were 97%, and 94.7%, respectively, with no difference between the PMRT (n=191) and no-PMRT (n=508) subgroups. No constructed subtype was associated with an increased risk of LRR. Ki67 >20% was the only independent prognostic factor associated with increased LRR (hazard ratio, 4.18; 95% CI, 1.11-15.77; P<.0215). However, PMRT was not associated with better locoregional control in patients with proliferative tumors. Conclusions: Ki67 expression but not molecular subtypes are predictors of locoregional recurrence in breast cancer patients with negative lymph nodes after MRM. The benefit of adjuvant RT in patients with proliferative tumors should be further investigated in prospective studies.

    Liposomes are recognized drug delivery systems with tumor-targeting capability. In addition, therapeutic or diagnostic radionuclides can be efficiently loaded into liposomes. This study investigated the feasibility of utilizing radiotherapeutic liposomes as a new post-lumpectomy radiotherapy for early-stage breast cancer by determining the locoregional retention and systemic distribution of liposomes radiolabeled with technetium-99m (99mTc) in an orthotopic MDA-MB-231 breast cancer xenograft nude rat model. To test this new brachytherapy approach, a positive surgical margin lumpectomy model was set up by surgically removing the xenograft and deliberately leaving a small tumor remnant in the surgical cavity. Neutral, anionic, and cationic surface-charged fluorescent liposomes of 100 and 400 nm diameter were manufactured and labeled with 99mTc-BMEDA. Locoregional retention and systemic distribution of 99mTc-liposomes injected into the post-lumpectomy cavity were determined using non-invasive nuclear imaging, ex vivo tissue gamma counting and fluorescent stereomicroscopic imaging. The results indicated that 99mTc-liposomes were effectively retained in the surgical cavity (average retention was 55.7 ± 24.2% of injected dose for all rats at 44 h post-injection) and also accumulated in the tumor remnant (66.9 ± 100.4%/g for all rats). The majority of cleared 99mTc was metabolized quickly and excreted into feces and urine, exerting low radiation burden on vital organs. In certain animals 99mTc-liposomes significantly accumulated in the peripheral lymph nodes, especially 100 nm liposomes with anionic surface charge. The results suggest that post-lumpectomy intracavitary administration of therapeutic radionuclides delivered by 100-nm anionic liposome carrier is a potential therapy for the simultaneous treatment of the surgical cavity and the draining lymph nodes of early-stage breast cancer.

    Purpose: To assess the adequacy of nodal coverage of 'conventional' pelvic radiation fields for carcinoma of the cervix, with contoured pelvic vessels on simulation computed tomography (CT) as surrogates for lymph node location. Methods and Materials: Pelvic arteries were contoured on non-contrast-enhanced CT simulation images of 43 patients with cervix cancer, FIGO Stages I-III. Vessel contours were hidden, and conventional pelvic fields were outlined: (1) anterior/posterior fields (AP): superior border, L5-S1 interspace; inferior border, obturator foramina; lateral border, 2 centimeters lateral to pelvic brim. (2) Lateral fields (LAT): Anterior border, symphysis pubis; posterior border, S2-S3 interspace. Distances were measured between the following: (1) bifurcation of the common iliac artery and superior border (2) external iliac artery and lateral border of the AP field, and (3) external iliac artery and anterior border of the LAT field. The distances were considered as 'inadequate' if <15 mm, 'adequate' if 15-20 mm, and 'generous' if >20 mm. Results: Superiorly, 34 patients (79.1%) had inadequate coverage. On the AP, margins were generous in 19 (44.2%), but inadequate in 9 (20.9%). On the LAT, margins were inadequate in 30 (69.8%) patients. Overall, 41 (95.4%, CI, 84.2%-99.4%) patients had at least 1 inadequate margin, the majority located superiorly. Twenty-four (55.8%; CI, 39.9%-70.9%) patients had at least 1 generous margin, the majority located laterally on the AP field. Conclusion: Conventional pelvic fields based on bony landmarks do not provide optimal lymph node coverage in a substantial proportion of patients and may include excess normal tissue in some. CT simulation with vessel contouring as a surrogate for lymph node localization provides more precise and individualized field delineation.

    The present study presents a novel near-infrared optical probe for the sentinel lymph node (SLN) detection in breast cancer patients, based on the recording of scattered photons. The aim of this study was to improve the detection of patent blue V (PBV), a dye routinely injected during clinical practice. A combined injection of the dye and radioactive colloid was used in the 24 patients enrolled in the study. The clinical results of the ex vivo detection of 70 dye-marked SLNs are reported, subsequent to the injection of various quantities of PBV (0.25-2 ml). The accuracy and success rate of an isotopic probe for the detection of radioactive colloid tracer, the eye visibility threshold of the surgeon and the use of a new optical probe were examined. The radio-labeled and dye-marked sentinel lymph nodes were all detected by the radio-isotopic probe, as opposed to the 75% detected by the eye visibility threshold of the surgeon. The optical probe detected all of the nodes, regardless of the volume of the dye injected. The relative PBV concentration computed by the probe facing SLNs with infravisible/visually undetectable dye-mark was relatively constant at 5.5±1.4 ?mol/l. The optical detection of the sentinel lymph nodes using PBV and the probe presented in this study have the potential to reduce the false negative detection rate. This instrument is likely to provide surgeons with a simple diagnostic tool, without significantly changing their surgical procedures. PMID:24649137

    Dosimetric differences were investigated among single and dual arc RapidArc and fixed-field intensity-modulated radiotherapy (f-IMRT) treatment plans for whole pelvic irradiation of lymph nodes. A total of 12 patients who had undergone radical surgery for cervical cancer and who had demonstrated multiple pelvic lymph node metastases were treated with radiotherapy. For all 12 cases, 7-field IMRT, single-arc RapidArc and dual-arc RapidArc were applied with 6 MV and 15 MV X-ray energies. The radiation dosimetric parameters for the different plans were compared with one another. All the plans met the clinical requirements. The homogeneity, conformity and external volume indices of f-IMRT and dual-arc RapidArc were better than for single-arc RapidArc (P < 0.05), while the differences between f-IMRT and dual-arc RapidArc were not significant. There were no significant differences in the radiation dose to organs at risk, except for the small bowel receiving >40 Gy (f-IMRT and dual-arc < single-arc, P < 0.05). The differences in dose distributions between the two applied X-ray energies for each of the modality plans were not significant. RapidArc plans resulted in fewer monitor units than the corresponding f-IMRT plans. Also, there were no differences between the two photon energies, except for a reduction in the number of MUs for 15 MV (P > 0.05). Compared to f-IMRT, no significant dosimetric benefits were found using RapidArc for whole pelvic lymph node irradiation. However, RapidArc has been associated with shorter treatment time and fewer monitor units, supporting the case for its safety and efficacy for pelvic irradiation. PMID:23283869

    A 17-year-old man was seen with an expanding false aneurysm of the right axillary artery. This was treated by an intraluminal covered-stent introduced through the brachial artery via an 11F sheath. The covered-stent was constructed from a segment of great saphenous vein anchored in the axillary artery by a 29 mm Palmaz stent. Postoperative arteriography and duplex scanning confirmed normal flow through the axillary artery with complete exclusion of the aneurysm. Postoperative recovery was uneventful. PMID:10412931

    SPECT/CT reinforces the role of lymphoscintigraphy in breast cancer by solving some cases with difficult reading on planar scintigraphy. An 80-year-old woman was referred to our institution for management of a screen-detected, nonpalpable, invasive lobular carcinoma of lower inner quadrant of the left breast. Lymphoscintigraphy was performed before surgery. Planar images showed an axillary sentinel node and 2 medially located hot spots. SPECT/CT allowed determining that one of the extra-axillary drainage sites was to the internal mammary basin, while the second corresponded to a mediastinal lymph node. Although this drainage was unexpected, mediastinum is a common site of breast cancer recurrence. PMID:23797233

    In breast cancer, single-photon emission computed tomography/computed tomography (SPECT/CT) shows the exact anatomical location of sentinel nodes (SN). SPECT/CT mainly exposes axilla and partly exposes atypical sites of extra-axillary lymphatic drainage. The mechanism of how the atypical hot nodes are involved in lymphatic metastasis was retrospectively investigated in the present study, particularly at the level II/III region. SPECT/CT was performed in 92 clinical stage 0-IIA breast cancer patients. Sentinel lymph nodes are depicted as hot nodes in SPECT/CT. Patients were divided into two groups: With or without hot node in level II/III on SPECT/CT. The existence of metastasis in level II/III was investigated and the risk factors were identified. A total of 12 patients were sentinel lymph node biopsy metastasis positive and axillary lymph node dissection (ALND) was performed. These patients were divided into two groups: With and without SN in level II/III, and nodes in level II/III were pathologically proven. In 11 of the 92 patients, hot nodes were detected in level II/III. There was a significant difference in node metastasis depending on whether there were hot nodes in level II/III (P=0.0319). Multivariate analysis indicated that the hot nodes in level II/III and lymphatic invasion were independent factors associated with node metastasis. There were 12 SN-positive patients followed by ALND. In four of the 12 patients, hot nodes were observed in level II/III. Two of the four patients with hot nodes depicted by SPECT/CT and metastatic nodes were pathologically evident in the same lesion. Therefore, the present study indicated that the hot node in level II/III as depicted by SPECT/CT may be a risk of SN metastasis, including deeper nodes. PMID:25289038

    Proteins are used as prognostic and predictive biomarkers in breast cancer. However, the variability of protein expression within the same tumor is not well studied. The aim of this study was to assess intratumoral heterogeneity in protein expression levels by reverse-phase-protein-arrays (RPPA) (i) within primary breast cancers and (ii) between axillary lymph node metastases from the same patient. Protein was extracted from 106 paraffin-embedded samples from 15 large (?3 cm) primary invasive breast cancers, including different zones within the primary tumor (peripheral, intermediate, central) as well as 2–5 axillary lymph node metastases in 8 cases. Expression of 35 proteins including 15 phosphorylated proteins representing the HER2, EGFR, and uPA/PAI-1 signaling pathways was assessed using reverse-phase-protein-arrays. All 35 proteins showed considerable intratumoral heterogeneity within primary breast cancers with a mean coefficient of variation (CV) of 31% (range 22–43%). There were no significant differences between phosphorylated (CV 32%) and non-phosphorylated proteins (CV 31%) and in the extent of intratumoral heterogeneity within a defined tumor zone (CV 28%, range18–38%) or between different tumor zones (CV 24%, range 17–38%). Lymph node metastases from the same patient showed a similar heterogeneity in protein expression (CV 27%, range 18–34%). In comparison, the variation amongst different patients was higher in primary tumors (CV 51%, range 29–98%) and lymph node metastases (CV 65%, range 40–146%). Several proteins showed significant differential expression between different tumor stages, grades, histological subtypes and hormone receptor status. Commonly used protein biomarkers of breast cancer, including proteins from HER2, uPA/PAI-1 and EGFR signaling pathways showed higher than previously reported intratumoral heterogeneity of expression levels both within primary breast cancers and between lymph node metastases from the same patient. Assessment of proteins as diagnostic or prognostic markers may require tumor sampling in several distinct locations to avoid sampling bias. PMID:22792263

    The present study aims to clarify whether hyaluronan binding protein 1 (HABP1/p32/C1QBP) is an indicator of peritoneal and lymph node metastasis in epithelial ovarian cancer (EOC), which to the authors' knowledge is not previously reported by others. Western blot analysis demonstrated that HABP1 was highly overexpressed in most metastatic lesions. Of 89 patients whose primary tumors showed high HABP1 expression on immunohistochemical staining, 85 (95.5%) presented peritoneal metastases and 43 (48.3%) had lymph node metastases. Univariate and multivariate logistic regression analyses revealed that HABP1 overexpression correlated with peritoneal dissemination and lymph node metastasis in EOC. The specificity and positive predictive value of HABP1 staining were shown to be better for peritoneal metastasis, while the negative and sensitivity predictive value of HABP1 staining were better for lymph node metastasis. The odds ratio of high versus low staining for peritoneal spread was 9.236 (95% confidence interval (CI), 2.705, 19.316), and that for lymph node metastasis was 8.614 (95% CI, 2.507, 21.039). Furthermore, HABP1 protein may potentially be used alone or in combination with other markers as a predictive marker of EOC patients with lymph node metastasis and/or peritoneal dissemination.

    A widespread application of integrin ?v?3 imaging has been emerging in both pre-clinical and clinical studies. But few studies reported its value as compared with 18F-FDG PET, especially for differentiated thyroid cancer (DTC). In this study, we compared the tracer uptake of 18F-AIF-NOTA-PRGD2 and 18F-FDG in lymph node metastasis of DTC to evaluate 18F-AIF-NOTA-PRGD2 as compared with 18F-FDG. Methods 20 DTC patients with presumptive lymph node metastasis were examined with 18F-AIF-NOTA-PRGD2 and 18F-FDG PET/CT. 16 patients undergoing fine needle aspiration biopsy (FNAB) were evaluated by cytology results. For lesions without FNAB, the findings of clinical staging procedures served as the standard of reference (including neck ultrasound and serum thyroglobulin). Results A total of 39 presumptive lymph node metastases were visualized on PET/CT images. 35 lesions were confirmed as malignant by FNAB and other clinical findings. The mean 18F-AIF-NOTA-PRGD2 in radioactive iodine-refractory (RAIR) lesions and benign lesions were 2.5±0.9 and 2.8±0.9 respectively. The mean SUV for 18F-FDG in all malignant lesions was 4.5±1.6 while in benign lesions it was 3.3±1.2. For all malignant lesions, the mean SUV for 18F-FDG was significantly higher than that for 18F-AIF-NOTA-PRGD2 (P<0.05). No significant correlation was found between the SUVs of 18F-AIF-NOTA-PRGD2 and 18F-FDG for 35 lesions (r?=?0.114, P?=?0.515). Moreover, 15 lesions of which the diameter larger than 1.5cm had higher 18F-AIF-NOTA-PRGD2 uptake as compared with the lesions smaller than 1.5cm. Conclusion Although most lymph node metastases of DTC showed abnormal uptake of 18F-AIF-NOTA-PRGD2, its diagnostic value was inferior to 18F-FDG. No correlation was found between the uptake of 18F-AIF-NOTA-PRGD2 and 18F-FDG, which may suggest the two tracers provide complementary information in DTC lesions. PMID:24956393

    Background Serum carcinoembryonic antigen (sCEA) level might be an indicator of disease. Indeed, an elevated sCEA level is a prognostic factor in colorectal cancer (CRC) patients. However, the genetic determinants of sCEA level in healthy and CRC population remains unclear. Thus we investigated the genetic markers associated with elevated serum sCEA level in these two populations and its clinical implications. Methods and Findings Genome-wide association study (GWAS) was conducted in a cohort study with 4,346 healthy male adults using the Illumina Omni 1 M chip. Candidate SNPs associated with elevated sCEA levels were validated in 194 CRC patients on ABI Taqman platform. Eight candidate SNPs were validated in CRC patients. The rs1047781 (chr19- FUT2) (A/T) was associated with elevated sCEA levels, and rs8176746 (chr9- ABO) was associated with the regional lymph metastasis in the CRC patients. The preoperative sCEA level was a risk factor for tumor recurrence in 5 years after operation (OR?=?1.427, 95% CI: 1.005?1.843, P?=?0.006). It was also one of the risk factors for regional lymph node metastasis (OR?=?2.266, 95% CI: 1.196?4.293, P?=?0.012). The sCEA level in rs1047781-T carriers was higher than that in the A carriers in CRC patients without lymph node metastasis (P?=?0.006). The regional lymph node metastasis in patients with homozygote AA of rs8176746 was more common than that in the heterozygote AG carriers (P?=?0.022). In addition, rs1047781-AT and TT CRC patients exhibited a worse disease-free survival than AA genotype carriers (P?=?0.023). Conclusions We found candidate SNPs associated with elevated sCEA levels in both healthy males and CRC population. Rs1047781 (chr19- FUT2) may be the susceptible locus for recurrence of CRC in a population from Southern China. PMID:24941225

    Preoperative (neoadjuvant) chemotherapy (NC) has become the standard of care for patients with locally advanced breast cancer and is being increasingly used in those with large operable disease. Its main clinical advantages from a surgical therapy standpoint include the potential for conversion of patients requiring mastectomy to breast-conservation candidates, the potential for improving the cosmetic outcome following lumpectomy by decreasing the size of the primary breast tumor even if the patient is a lumpectomy candidate at presentation, and the potential for converting patients who present with positive axillary nodes and who would initially require axillary lymph node dissection to candidates for sentinel lymph node biopsy alone. Important steps are required from the time of diagnosis until the time of surgical resection to ensure successful locoregional therapy outcomes in patients treated with NC. They include accurate assessment of the location and extent of the primary breast tumor and determination of axillary nodal status before and after NC. This information is critical for successful execution of the surgical plan and to optimize the use of adjuvant radiotherapy following NC. In the future, development of more active neoadjuvant chemotherapy regimens and novel molecular and imaging techniques will undoubtedly lead to further individualization of breast cancer surgical management following NC, including the possibility of avoiding surgical resection in cases with a high likelihood of achieving a pathological complete response.

    Toll-like receptor (TLR)4-mediated signaling has been implicated in tumor cell invasion, survival, and metastasis in a variety of cancers. This study investigated the expression and biological role of TLR4 in human breast cancer metastasis. MCF-7 and MDA-MB-231 are human breast cancer cell lines with low and high metastatic potential, respectively. Using lipopolysaccharide (LPS) to stimulate MCF-7 and MDA-MB-231 cells, expression of TLR4 mRNA and protein increased compared with that in control cells. TLR4 activation notably up-regulated expression of matrix metalloproteinase (MMP)-2, MMP-9 and vascular endothelial growth factor(VEGF) mRNA and their secretion in the supernatants of both cell lines. LPS enhanced invasion of MDA-MB-231 cells by transwell assay and MCF-7 cells by wound healing assay. LPS triggered increased expression of TLR4 downstream signaling pathway protein myeloid differentiation factor 88(MyD88) and resulted in interleukin (IL)-6 and IL-10 higher production by human breast cancer cells. Stimulation of TLR4 with LPS promoted tumorigenesis and formed metastatic lesions in liver of nude mice. Moreover, expression of TLR4 and MyD88 as well as invasiveness and migration of the cells could be blocked by TLR4 antagonist. Combined with clinicopathological parameters, TLR4 was overexpressed in human breast cancer tissue and correlated with lymph node metastasis. These findings indicated that TLR4 may participate in the progression and metastasis of human breast cancer and provide a new therapeutic target. PMID:25299052

    Purpose: To evaluate overall survival (OS), progression-free survival (PFS), loco-regional recurrence (LRR), and toxicities for early breast-cancer patients with one to three positive axillary lymph nodes, by the addition of radiotherapy to adjuvant chemotherapy. Patients and methods: Patients were eligible for enrollment into the study if they had pathologically proven stages II breast cancer, with one to three positive axillary lymph nodes. Patients were assigned to one of the two groups; Group 1; adjuvant chemotherapy then radiotherapy, and group 2; adjuvant chemotherapy only. Results: Between September 2008 and August 2014, 75 patients were enrolled. Forty patients group 1, and 35 group 2. The 4-year OS for group 1, and two were 77.5 and 71.4%, respectively. The 4-year PFS for group 1 and 2 were 72.5 and 60%, respectively. During the 54?months follow-up period, 11 patients from group 1 had recurrence (three locoregional, seven metastatic, and one both), and 14 patients from group 2 had recurrence (seven locoregional, three metastatic, and four both). The distant metastasis rate was the same in the two groups. However, the metastasis sites were different in the two groups. Conclusion: The addition of radiotherapy in stage II breast cancer with one to three positive lymph nodes improved the PFS, and LRR. Radiotherapy improved OS in patients with high-risk features.

    Background: Kynurenic acid (KYNA) is a side-stream product of the kynurenine metabolic pathway that plays a controversial role in malignancies either enabling escape of malignant cells from immune surveillance or exerting antiproliferative effect on cancer cells, and is associated with differences in invasiveness related to metastatic spread to lymph nodes in lung cancer. Nodal involvement is a significant negative prognostic factor usually considered a contraindication for primary surgical resection. Objective: To assess potential value of circulating KYNA for non-invasive identification of patients with metastatic lymph nodes (N+) in non-small cell lung cancer (NSCLC). Methods: KYNA level in venous blood serum was determined with use of high performance liquid chromatography (HPLC) in 312 subjects including 230 patients with NSCLC and 32 healthy controls. Results: Circulating KYNA level in NSCLC patients was higher than in controls (93.6±61.9pmol/ml vs. 31.4±16.6pmol/ml; p=2.2•10-15) and positively correlated with N (R=0.326; p=2•10-6) but not with T or M stage (p>0.05). In N+ patients it was higher than in N0 patients (137.7±51.8pmol/ml vs. 71.9±41.7pmol/ml; p=4.8•10-16). KYNA effectively discriminated N+ from N0 patients at a cut-off value 82.3 pmol/ml with sensitivity 94.7% (95%CI 87.1-98.5%), specificity 80.5% (95%CI 73.4-86.5%), negative predictive value NPV=96.8%, PPV=70.5% and area under the ROC curve AUC=0.900 (95%CI 0.854-0.935; p=0.0001). Discussion and Conclusion: Circulating KYNA level measurement offers reliable non-invasive discrimination between N0 and N+ patients in NSCLC. Robust discriminatory characteristics of KYNA assay predestines it for clinical use as an adjunct facilitating selection of candidates for primary surgical resection. PMID:25589891
