BackgroundBreast cancer is a heterogeneous disease which is divided broadly into luminal, HER2 and basal type based on molecular profiling. Increased body mass index (BMI) has been associated with the risk of developing breast cancer but the association based on molecular subtype remains conflicting.MethodsThis was an observational study carried out over a period of 2 years. Nonmetastatic breast cancer patients were evaluated for the tumour subtype based on surrogate markers (ER, PR and HER2). The BMI of these patients was correlated with the tumour subtype and size.ResultsWe studied 476 patients with breast cancer with the median age of 46 years (range, 25–86) and 58% were premenopausal. The mean BMI of the cohort was 24.1, which was significantly higher in postmenopausal women (24.9 versus 23.6, p < 0.05). Overall, only 10% of patients were obese. The mean BMI in the luminal, HER2 and TNBC subtypes was 24.7, 22.4 and 23.9, respectively (p < 0.01). Also, the mean tumour size in luminal, HER2 and TNBC subtype was 4.02, 3.80 and 4.27 cm, respectively (p = 0.158).ConclusionThe average BMI was higher in patients with luminal subtype followed by TNBC and lowest for HER2 at the time of diagnosis. The mean tumour size was numerically higher for TNBC and lowest for HER2 subtype although the difference was not statistically significant. Larger studies may provide clarity of association between the BMI and tumour subtype.

IC had a manageable toxicity profile and achieved resectability in 19% of our patients with T4b OSCC. Patients underwent resection had a significantly better median OS than those who received nonsurgical local treatment.

Non-small cell lung cancer ranks among the most lethal cancers worldwide. The rate of epidermal growth factor receptor (EGFR) mutations and echinoderm microtubuleassociated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) gene fusion is the most common in younger age, non-smoking Asian adenocarcinoma lung cancer patients. EGFR mutations and ALK gene rearrangements are known to be mutually exclusive and as mutual causes of resistance to EGFR-tyrosine kinase inhibitors (TKIs) or ALK-TKIs. However, rarely such co-alterations do co-exist in some clinical cases. Here we report a 62 year old male, heavy smoker with cough, hemoptysis and fatigue. Histopathological examination of bronchoscopic guided biopsy showed adenocarcinoma histology. Staging evaluation, he was found to have stage IV disease on positron emission tomography-computed tomography scan. The biopsy blocks tested positive for both EGFR mutation and ALK fusion. Patient was initiated on tablet Gefitinib 250 mg once daily. To the best of our knowledge, there has been no report of dual EGFR mutation and ALK fusion positivity from India.
