Background Pathological complete response (pCR) to neoadjuvant chemotherapy has emerged as a reliable surrogate marker for improved survival in breast cancer (BC), but its role as a surrogate end point is still controversial. Aims and Objectives The aim of the study is to investigate the clinical course of BC patients with pCR and to evaluate the relevance of pCR as a surrogate end point for survival. selleck chemical Materials and Methods This was a single-institution retrospective analysis done at Amrita Institute of Medical Sciences. Records of BC patients from 2004 to 2014 were analyzed. Disease-free survival (DFS) and overall survival (OS) were compared using the Kaplan-Meier method and log-rank test, respectively. pCR and survival association were evaluated using regression analysis ( R 2 ). Results Of 224 patients included in the study pCR rate was 15.2%. The median duration of follow-up was 61 months (range 3-151 months). DFS (73.4 vs. 46.1%, p = 0.032) and OS (82.5 vs. 56.4%, p = 0.022) of pCR cohort was significantly higher than non-pCR cohort. Recurrence rate was significantly lower in the pCR cohort at All distant sites ( p = 0.01 3), visceral sites ( p = 0.007), both bone and visceral sites ( p = 0.007), and nodal sites ( p = 0.007). There was no difference in the bone-only recurrence ( p = 0.3 15). Death rate was significantly lower in pCR cohort ( p = 0.007). The R2 value for pCR as a surrogate for DFS and OS was 0.006 and 0.004, respectively. Conclusion pCR is a favorable prognostic factor associated with improved survival. However, there is no association between pCR and survival.Purpose Development of cancer chemotherapy treatment-induced hyperglycemia/ diabetes (secondary diabetes) is a major problem and has never been reported from India. The present study was planned to ascertain this in women undergoing curative chemotherapy for their breast cancer. Materials and Methods This was a retrospective chart-based study and was conducted in a cancer specialty hospital. The information on women who were nondiabetic at the start of the treatment was collected from the files. Details on cancer diagnosis, domicile, body mass index (BMI), type of diet, marital status, number of children, and previous history of diabetes if any were considered. The blood glucose levels before surgery and after the completion of radiotherapy were considered. World Health Organization (WHO) guidelines for diabetes were considered. The data were subjected to frequency and percentage and analyzed using Chi-square test. Association between the demographic details and development of Hyperglycemia or secondary diabetes or prediabetes was done using the Pearson's correlation analysis. p less then 0.05 was considered as statistically significant. Results A total of 474 cases were included in accordance with the inclusion criteria. The results indicated that by the end of the radiation treatment, 24.89% were prediabetic, 10.97% were diabetic after being in prediabetic stage, 8.22% became diabetic without going through a prediabetic stage, and that 55.91% did not develop either prediabetic or diabetic condition. Analysis of development of secondary diabetes and prediabetes with BMI ( p less then 0.0001) and age ( p less then 0.024) showed a strong correlation and was significant. Conclusion To the best of the authors' knowledge, this is the first study from India, and the results indicate that the development of secondary diabetes in women undergoing curative chemotherapy is high. Attempts are underway to ascertain the cause for the development and how it can be mitigated.Background Glioblastoma multiforme (GBM) is a disease with poor outcome. Alterations or mutations in epidermal growth factor receptors (EGFRs) are found in GBM and may be targeted to improve outcomes. Aims We analyzed the frequency of EGFR variant III (vIII) mutations in patients with GBM and their outcomes after standard treatment. Materials and Methods This is a retrospective study conducted in a single tertiary cancer center in south India. Forty patients with GBM who had their entire treatment done at this center were identified, and their primary tumor tissue blocks were retrieved. Genomic DNA was extracted, and molecular analysis was performed and analyzed. The results of mutational analysis were correlated with treatment outcome of the patients. Statistical Analysis Survival outcome was analyzed using the Kaplan-Meier method. The log-rank test was used to assess the association between the groups and various parameters. Results Our study showed a similar incidence of EGFR vIII alterations as published in world literature, but we did not find any difference in overall survival (OS) and progression-free survival (PFS) in patients with EGFR vIII mutation compared with nonmutant cohort. Conclusions Contrary to the existing literature which indicated EGFR vIII alterations to be a negative prognostic indicator, our study did not find it to be an independent predictor of prognosis among Indian GBM patients treated with present standard of care.Purpose The purpose of the study was to evaluate the short-term response and acute toxicities in muscle-invasive carcinoma urinary bladder treated with neoadjuvant chemotherapy followed by concurrent chemoradiation. Materials and Methods Thirty patients with muscle-invasive bladder cancer were treated with three cycles of neoadjuvant chemotherapy every 3 weeks. Response assessment was done after 4 weeks with repeat cystoscopy and imaging. Responders were treated with concurrent chemoradiation 60 Gy/30# at 2 Gy/# along with weekly injection cisplatin 35 mg/m 2 . Response assessment was done by new response evaluation criteria in solid tumors (version 1.1). Treatment-related acute toxicities were scored using common terminology criteria for adverse events version 4.0. Results Of the 30 patients, 25 patients responded to neoadjuvant chemotherapy with complete response in 17 patients (56.67%) and partial response in eight patients (26.66%). Five patients (16.66%) showed poor response and were advised radical cystectomy, of which four underwent radical cystectomy and one patient opted for concurrent chemoradiation.
