Prognostic and predictive value of tumoral DNA damage repair protein expression in patients with resected pancreatic cancer.

Objective: DNA damage repair (DDR) gene mutations gained interest in the treatment of metastatic pancreatic cancer (PC) patients, but their relevance in adjuvant setting is not well characterized. We assessed the prognostic and predictive potential of tumoral expression of DDR proteins along with clinical and tumor characteristics in patients with resected PC.

Patients And Methods: Patients with PC who underwent pancreatic resection in our institution between 2005 and 2017 were retrospectively retrieved.

Effects of 5-fluorouracil released from different prosthetic meshes on post-operative adhesion formation in rats.

Objective: Post-operative adhesion is a common problem in abdominal surgery. Especially, foreign materials are strong stimulus for the development of adhesions. The aim of this study was to investigate whether drug release material coated prosthetic mesh decreases intra-abdominal adhesion formation or not.

Human splenic polymorphonuclear myeloid-derived suppressor cells (PMN-MDSC) are strategically located immune regulatory cells in cancer.

In contrast to the mouse, functional assets of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSC) in the human spleen remain to be better elucidated. Here, we report that the spleen in gastric and pancreatic cancer adopts an immune regulatory character, harbors excessive amount of PMN-MDSC, and anatomically enables their interaction with T cells. Compared to the peripheral blood, the spleen from cancer patients contained significantly higher levels of low-density PMN-MDSC, but not early-stage MDSC (e-MDSC) and monocytic-MDSC (M-MDSC).

CD66b monocytes represent a proinflammatory myeloid subpopulation in cancer.

Myeloid-derived suppressor cells (MDSC) populate the peripheral blood and contribute to immune regulation in cancer. However, there is limited knowledge on the myeloid cell types with proinflammatory capacities that may serve as opponents of MDSC. In the circulation of cancer patients, a monocyte subpopulation was identified with a specific immunophenotype and transcriptomic signature.

Cyst of the canal of nuck: A rare cause of inguinal swelling in women.

Among various reasons of swellings in the female inguinal region nuck canal cysts are rare entities. Abnormal persistence of procesus vaginalis opening cause this formation. Presentation at adults can lead misdiagnosis.
