Assessing nearly 14,000 women from a contemporary United States database, this is the largest known study examining the relationship between response to NC and molecular subtype. Women with luminal A disease are the least likely to undergo pCR, with the highest rates in Her2 disease. Degree of response is associated with OS, especially in luminal B, Her2, and TN patients. Despite the comparatively higher likelihood of achieving pCR in TN cases, this subgroup may still experience a survival detriment, which has implications for an ongoing national randomized trial.

BackgroundCancer cachexia negatively impacts cancer‐related treatment options, quality of life, morbidity, and mortality, yet no established therapies exist. We investigated the anabolic properties of testosterone to limit the loss of body mass in late stage cancer patients undergoing standard of care cancer treatment.MethodsA randomized, double‐blind, placebo‐controlled phase II clinical trial was undertaken to assess the potential therapeutic role of adjunct testosterone to limit loss of body mass in patients with squamous cell carcinoma of the cervix or head and neck undergoing standard of care treatment including chemotherapy and chemoradiation. Patients were randomly assigned in blocks to receive weekly injections of either 100 mg testosterone enanthate or placebo for 7 weeks. The primary outcome was per cent change in lean body mass, and secondary outcomes included assessment of quality of life, tests of physical performance, muscle strength, daily activity levels, resting energy expenditure, nutritional intake, and overall survival.ResultsA total of 28 patients were enrolled, 22 patients were studied to completion, and 21 patients were included in the final analysis (12 placebo, nine testosterone). Adjunct testosterone increased lean body mass by 3.2% (95% confidence interval [CI], 0–7%) whereas those receiving placebo lost 3.3% (95% CI, −7% to 1%, P = 0.015). Although testosterone patients maintained more favourable body condition, sustained daily activity levels, and showed meaningful improvements in quality of life and physical performance, overall survival was similar in both treatment groups.ConclusionsIn patients with advanced cancer undergoing the early phase of standard of care therapy, adjunct testosterone improved lean body mass and was also associated with increased quality of life, and physical activity compared with placebo.

With the development of the coronavirus disease 2019 (COVID-19) pandemic, health care practices and radiation oncology departments have begun to incorporate telemedicine services to practice social distancing and minimize the chances of disease spread. Given the severity of this pandemic, it will likely fundamentally affect the use of these services for years to come. Our institution and radiation oncology department have used telemedicine services for many years; we would like to report on our departmental experience to guide other radiation oncology practices on its long-term use for clinical evaluation and patient care. Methods and Materials: Our institution's telemedicine program provides clinical services for a number of remote locations and represents the largest telehealth network in the world, with over 300 sites and 60,000 patient encounters a year. Results: Specifically for our radiation oncology department, over 200 patient encounters occur via telemedicine a year. Patients report great appreciation and satisfaction with these encounters, as they eliminate the time and energy needed for travel from long distances. It has resulted in improved efficiency and cost-effectiveness as well. Conclusions: Based on our institutional experience, our long-term vision for telemedicine (after COVID-19 pandemic has hopefully subsided) is as an excellent and cost-efficient tool to provide long-term follow-up for patients, especially for those who live far away in rural or underserved areas.

Purpose Metaplastic breast cancer (MBC) is a rare, aggressive variant of breast cancer that has been associated with poor clinical outcomes, as has triple-negative breast (TNBC) cancer. Limited studies compare the clinical characteristics and prognosis of MBC to TNBC. This study uses a large, contemporary US cancer database to compare clinical characteristics and survival outcomes for patients with MBC to those with TNBC. Methods The National Cancer Database was queried for women with cT1-4N1-3M0 MBC or TNBC diagnosed between 2004 and 2013 and treated with definitive surgery. Chi-squared analysis was performed to determine differences between the cohorts. Kaplan-Meier curves compared overall survival (OS), and Cox regression determined patient factors associated with OS. Results Altogether, 55,847 patients met the inclusion criteria; 50,705 (90.8%) had TNBC and 5,142 (9.2%) had MBC. Most patients had no comorbid conditions (82%), N0 disease (71%), poorly differentiated histology (77%), received chemotherapy (87%), and received radiation therapy (60%). Amongst all patients, patients with TNBC disease were observed to have greater OS than those with MBC (5-year OS 72.0% vs 55.8%, p < 0.001). The greater observed OS for patients with TNBC persisted when controlling for stage and when comparing propensity score matched cohorts. On Cox regression, lower age, T1 status, N0 status, chemotherapy, TNBC disease, and radiation therapy (RT) were associated with improved OS. Conclusions MBC had an association with poorer OS compared to TNBC, while RT and chemotherapy receipt were associated with improved OS for patients regardless of stage. Further studies are needed to corroborate the conclusions herein.

BackgroundInvasive micropapillary carcinoma (IMPC) is an uncommon subtype of breast cancer. Previous studies of this subtype demonstrated a higher propensity for lymph node metastases as compared with invasive ductal carcinoma (IDC). The purpose of the present study was to determine the clinical characteristics, outcomes, and propensity for lymph node metastasis of patients with IMPC of the breast recorded in the National Cancer Database (NCDB).MethodsRecords of patients with IMPC diagnosed between 2004 and 2014 were retrieved from the NCDB. Log-rank test was performed to evaluate associations of clinical characteristics with overall survival (OS). Cox proportional hazards model was used to determine variables associated with OS.ResultsOverall, 2660 patients with IMPC met the selection criteria; the 5-year OS rate was 87.5% and 24.9% of patients had nodal involvement at presentation. Patients with ≥ 4 positive lymph nodes had shorter OS than node-negative patients, whereas patients with 1–3 positive nodes had similar OS to node-negative patients. Age < 65 years, receipt of radiotherapy, and estrogen receptor positivity were also associated with prolonged OS. The benefit of radiotherapy was limited to IMPC patients undergoing lumpectomy; there was no benefit for the patients undergoing mastectomy (regardless of nodal positivity/negativity).ConclusionsFavorable prognostic factors of IMPC patients included age < 65 years, < 4 positive lymph nodes, receipt of radiotherapy, and estrogen receptor positivity. The results presented herein suggest a survival benefit associated with radiotherapy in IMPC treatment, though this may be limited to the patients treated with lumpectomy.

Background Prognosis and treatment options differ for each molecular subtype of breast cancer, but risk of regional lymph node (LN) metastasis for each subtype has not been well-studied. Since LN status is the most important predictor for prognosis, the aim of this study is to investigate the propensity for LN metastasis in each of the five breast cancer molecular subtypes. Methods Under an IRB-approved protocol, we retrospectively reviewed the charts of all pathologically confirmed breast cancer cases from 1/2004 to 6/2012. Five subtypes were defined as luminal A (hormone receptor +, Ki67 low), luminal B (hormone receptor+, Ki67 high), luminal-human epidermal growth factor receptor 2 (HER-2), HER-2-enriched (hormone receptor negative), and triple negative (TN). Results A total of 375 patients with complete data were classified by subtype: 95 (25.3%) luminal A, 120 (32%) luminal B, 69 (18.4%) luminal-HER-2, 26 (6.9%) HER-2-enriched, and 65 (17.3%) TN. On univariate analysis, age (<50), higher tumor grade, HER-2 + status, tumor size, and molecular subtype were significant for LN positivity. Molecular subtype correlated strongly with tumors size (X2; p=0.0004); therefore, multivariable logistic regression did not identify molecular subtype as an independent variable to predict LN positivity. Conclusions Luminal A tumors have the lowest risk of LN metastasis, while luminal HER-2 subtype has the highest risk of LN metastasis. Immunohistochemical-based molecular classification can be readily performed and knowledge of the factors that affect LN status may help with treatment decisions.

BackgroundStandard-of-care (SOC) cancer treatments are primarily aimed at reducing size and progression of a tumor. There is a need for successful supplemental anabolic therapies to combat cancer cachexia in addition to these SOC treatment modalities. Anabolic interventions, including testosterone and amino acid supplements, may be beneficial in reducing and/or reversing muscle wasting in these patient populations.MethodsA 48-year-old Caucasian female with recurrent cervical cancer was scheduled to receive three 21-day cycles of cisplatin and topetecan chemotherapy. She qualified, consented, and enrolled into a blinded interventional pilot study where she received daily whey protein (10 g, three times per day with meals) and a weekly injection of testosterone enanthate (100 mg intramuscular) before and during the SOC chemotherapy treatment period. Body composition, serum inflammatory markers, mixed muscle protein synthesis and breakdown rates, physical function, fatigue, and quality of life were assessed before and after the intervention period.ResultsBody composition, as assessed by an increase in body weight and lean body mass and reduction in fat mass; physical function; fatigue; and quality of life each improved across the entire intervention period despite general increases in inflammatory markers and no improvements in muscle protein turnover towards the end of the intervention.ConclusionsConcomitant treatment of oral amino acids and testosterone may be a viable therapeutic option for fighting cachexia and improving body composition and quality of life during chemotherapeutic treatment of recurrent cervical cancer. These positive outcomes may be attainable over time despite overall poor inflammatory status.

Context.—Primary small cell neuroendocrine carcinoma of the vagina is extremely rare, and its clinical behavior is aggressive. To our knowledge, 22 patients with this tumor have been reported in the English literature to date. Objective.—To investigate 3 patients with this tumor clinically and pathologically. Design.—The pathology database at the University of Texas Medical Branch at Galveston was searched, and 3 cases of primary small cell neuroendocrine carcinoma of the vagina were found. The histologic, immunohistochemical, and ultrastructural profiles of the tumors were investigated. The medical charts of the patients were reviewed, and the patients were followed up. Patients.—Women with the diagnosis of primary small cell neuroendocrine carcinoma of vagina. Results.—All 3 patients presented with advanced disease, and 2 patients died within 4 months of the initial diagnosis. One 38-year-old patient was newly diagnosed, and her clinical outcome had not yet been determined. The histologic features of all 3 tumors were similar to those of their pulmonary counterpart. All cases were positive for cytokeratin, chromogranin A, and synaptophysin. The expression pattern of thyroid transcription factor 1 was examined in all 3 patients, of whom 2 were negative and 1 was positive with negative clinical and radiologic thyroid or pulmonary findings. Ultrastructural evaluation showed scattered intracytoplasmic electron-dense neurosecretory granules. Conclusion.—Primary small cell neuroendocrine carcinoma of the vagina has histologic, immunohistochemical, and ultrastructural features similar to those of its pulmonary counterpart. Because thyroid transcription factor 1 can be positive, it should not be used to differentiate primary from metastatic disease. The current therapies have usually resulted in poor outcomes, and new therapeutic modalities should be explored.
