Background: Cytoreductive surgery and heated intraperitoneal chemotherapy (CRS/HIPEC) are commonly used in the treatment of peritoneal carcinomatosis (PC) originating from colorectal, appendiceal and ovarian cancers. It is unclear what benefit CRS/HIPEC might have for PC from uncommon etiologies, therefore we sought to describe local practice patterns and evaluate overall survival (OS).

Background: Endoscopic resection (ER) has come to be recognized as a standard treatment for early gastric cancer (EGC). While its adoption is expanding, ER remains restricted to cases of EGC without lymph node metastasis for the treatment of local resection. On the other hand, histopathological analyses of surgically resected specimens of EGC have revealed the presence of lymph node (LN) metastasis in some cases of mucosal gastric cancer (MGC) and undifferentiated MGC (UD-MGC) is considered to have higher risk of nodal metastases than differentiated MGC (D-MGC).

Background: Inactivation of DNA mismatch repair (MMR) and the resulting microsatellite instability (MSI) are frequently observed in endometrial, stomach and colorectal cancers as well as more rarely in other solid tumor types. The prevalence of MSI in thyroid cancer has not been explored in-depth, although recent studies utilizing data from large cancer sequencing efforts such as The Cancer Genome Atlas indicate MSI is absent or at least very rare in the most common and most well-studied histologic subtype, papillary carcinoma. In this study, we aim to determine the prevalence of MSI in thyroid cancer by using a large series comprising all major histological subtypes. Read More

The elevated methionine (MET) requirement for the growth of tumors, first observed by Sugimura in 1959, termed MET dependence, is a potentially highly effective therapeutic target. Proof of this principle is that when MET restriction (MR) was initially established in co-cultures of cancer and normal cells, MET dependence could be exploited to selectively kill cancer cells without killing co-cultured normal cells. MET-dependent cells become reversibly blocked in the late S/G phase of the cell cycle under MR enabling selective and effective S-phase chemotherapy against these blocked cancer cells. Read More
