Male breast cancer (MBC) is an uncommon malignancy. The scarcity of cases has reduced the focus of research in this area as compared with female breast cancer. The incidence of breast cancer in males is slowly rising and it becomes important to study the biology of this uncommon illness. Aim of the present work was to study the clinico-pathological behaviour of male breast cancer at a cancer research institute in India. 18 cases of MBC were identified out of 1752 cases of breast cancer registered during a 10 year period. Clinical parameters and histopathological data were analysed. MBC comprised of 1.03 % of total breast cancer cases. Median age of presentation was 60 years. Most of the patients presented to us in advanced stage. Aggressive pattern of disease was recognised with high node positivity, more perineural spread and lymphovascular invasion. Most of the cases were positive for hormone receptors. Breast cancer is seen at a relatively early age in Indian males. Disease is aggressive in nature with high hormone receptor positivity.

Cutaneous metastasis (CM) from internal malignancies is commonly seen. Sometimes, skin metastases can be the first sign of advanced cancer or an indicator of cancer recurrence. Cases of breast cancer with cutaneous progression after or during trastuzumab therapy have been described in the past, frequently associated with systemic disease progression. However, CM during adjuvant trastuzumab therapy is very rare. It has been hypothesized that cancer cells located in the skin survive and take proliferative advantage by virtue of an immune-tolerance mechanism that hampers trastuzumab-mediated antibody-dependent cell-mediated cytotoxicity. We describe a case of human epidermal growth factor receptor-2-overexpressing breast cancer presenting with diffuse CM during adjuvant trastuzumab therapy.

SYNOPSISSimple stress-strain characteristics of silk do not give sufficient information on the influence of the rate of testing in silk. A methodology is described to quantify individual components of viscoelasticity which clearly brings out the influence of the strain rate on the viscous component of the system.

Background: First line (1L) TP-Ex-like regimen followed by 2nd-line (2L) immunotherapy represents one of the standards of care in platinum-sensitive recurrent and/or metastatic squamous cell carcinoma of head and neck (R/M SCCHN). We report our experience from 2 tertiary care institutions of India.  Methods: This is a retrospective analysis of consecutive patients of platinum-sensitive R/M SCCHN treated with 1L weekly paclitaxel, carboplatin, and cetuximab (PCC) regimen followed by cetuximab maintenance (if non-progressive) or 2L nivolumab or oral metronomic chemotherapy (OMCT) on progression. Overall response rates (ORR), progression-free survival after 1L and 2L (PFS-1 & PFS-2), overall survival (OS), and safety were evaluated.  Results: The study included 54 patients; median age 56.5 years; 89% men; 11% had cardiac dysfunction; 13% had renal dysfunction. After 1L PCC, ORR was 59.3%; median PFS-1 was 7.031 months; 61% had progression; 35% were treated with nivolumab and 18% with OMCT. The ORR was 26.3% (nivolumab) and 10% (OMCT). Median PFS-2 was 6.5 months (nivolumab) and 2 months (OMCT). The median OS was 15.01 months (entire cohort), 20.6 months (nivolumab), and 7 months (OMCT). Grade III/IV adverse events on PCC included neutropenia (31.4%), anaemia (35.1%), thrombocytopenia (7.4%), febrile neutropenia (11.1%), and skin reaction (16.6%); no Grade-III/IV treatment-related toxicities on 2L.  Conclusions: 1L weekly PCC is an effective regimen for palliative therapy of platinum- sensitive R/MSCCHN with an acceptable toxicity profile. The addition of 2L nivolumab on progression further improves the outcomes.
