TL;DR: Increased frequency of MDSCs, Th17 cells and decreased expression of CD3-ζ chain portray T cell tolerance and chronic inflammatory state facilitating tumor growth in oral squamous cell carcinoma patients.
Abstract: Oral tumor microenvironment is characterized by chronic inflammation signified with infiltrating leukocytes and soluble mediators which cause immune suppression. However, how immunosuppressive cells like myeloid-derived suppressor cells (MDSCs) maintain the immunosuppressive tumor microenvironment and influence T cell function in oral squamous cell carcinoma (OSCC) patients remains poorly understood. In the present study, we found that percentages of MDSCs were higher in oral cancer patients compared to healthy individuals and correlated with cancer stage. Monocytic MDSCs (M-MDSCs) were prevalent in the periphery, while granulocytic/polymorphonuclear subset dominated the tumor compartment. M-MDSCs suppressed the lymphocyte proliferation and decreased the CD3-ζ (zeta) chain expression and interferon gamma production. The percentage of M-MDSCs in peripheral blood correlated inversely with CD3-ζ chain expression in T cells of these patients. Interleukin 6 (IL-6)-induced phosphorylated STAT3-regulated programmed cell death ligand 1, CCAAT/enhancer-binding proteins alpha and beta and Interleukin 10 expression in MDSCs. MDSCs inhibited TGF-β-driven generation of induced regulatory T cells in vitro. M-MDSCs secreted interleukins IL-6, IL-1β, IL-23 and PGE2 and facilitated T-helper 17 (Th17) cell differentiation which utilizes nitric oxide synthase and cyclooxygenase 2 enzyme activity. Interestingly, OSCC patients showed increased levels of Th17 cells in peripheral blood and tumor tissue. Thus, increased frequency of MDSCs, Th17 cells and decreased expression of CD3-ζ chain portray T cell tolerance and chronic inflammatory state facilitating tumor growth.

TL;DR: The case of large-cell neuroendocrine carcinoma (LCNEC) of the endometrium in a 70-year-old female is described for its rarity and shows that a high index of suspicion can help the pathologist to use immunohistochemistry and in turn help in selection of appropriate chemotherapy.
Abstract: Neuroendocrine carcinomas (NEC) of the female genital tract are aggressive and uncommon tumors. They usually involve the cervix and ovary, and are seen very rarely in the endometrium. The overwhelming majority of endometrial NECs are of conventional small cell type (up to 60 cases). Only seven cases of large cell type NEC of the endometrium have been reported. We report a case of large-cell neuroendocrine carcinoma (LCNEC) of the endometrium in a 70-year-old female. The case is described for its rarity and shows that a high index of suspicion can help the pathologist to use immunohistochemistry and in turn help in selection of appropriate chemotherapy.

Journal ArticleDOI
TL;DR: This article is a retrospective analysis of patients who received weekly paclitaxel 50 mg/m2 and carboplatin AUC 2 with radical definitive RT for locally advanced esophageal/GEJ cancer, finding weekly pac litaxel–carboplatin concurrently with definitive RT is efficacious with manageable toxicity.
Abstract: There are little data on the efficacy and safety of taxane/platinum with definitive radiotherapy (RT) for esophageal/GEJ cancer. This article is a retrospective analysis of patients who received weekly paclitaxel 50 mg/m(2) and carboplatin AUC 2 with radical definitive RT for locally advanced esophageal/GEJ cancer. Between February 2011 and July 2014, 179 patients were included. The median age was 54 years. Ninety-two percent of patients had squamous histology. Mean RT dose was 58.7 Gy in 32 fractions over 53 days, with mean of six chemotherapy cycles. Fifty-six percent of patients developed ≥grade 3 acute toxicities, commonly febrile neutropenia (12%) and infection (11%); ≥grade 3 laboratory abnormalities included hyponatremia (38%), leukopenia (49%), neutropenia (27%), and anemia (16%). Twelve percent of patients developed ≥grade 3 chronic toxicity. Fatal toxicities included six during CRT, eight within 30 days of completing CRT, and three chronic. Radiologic response was 49% (CR 5.6%, PR 43%). Follow-up endoscopy showed remission in 53% and residual disease in 14%. At a median follow-up of 28 months, median PFS was 11 months (95% CI: 8-13.9), median OS was 19 months (95% CI: 15.4-22.6), and estimated 1-year, 2-year, and 3-year survivals were 70%, 47%, and 39%, respectively. Weekly paclitaxel-carboplatin concurrently with definitive RT is efficacious with manageable toxicity. [The trial was registered with the Clinical Trials Registry-India (CTRI), registration number: CTRI/2014/07/004776.].
