Published: April 2008

Colorectal cancer (CRC) cells (HT29) were injected into the intraperitoneal (i.p.) cavity of immunosuppressed male Sprague Dawley rats. Immunosuppression was achieved via a daily i.p. injection of cyclosporine 35 mg/kg/day. Three groups of rats (n = 6 per group) were injected with 20, 50 or 100 million HT29 cells. All animals developed tumours indicating that this animal model may prove useful for future research in human colorectal carcinomatosis.

Histologic grade is a key predictor for pseudomyxoma peritonei (PMP) of appendiceal origin that is used to guide clinical management. However, some tumors demonstrate disease behavior that deviates from their histologic grade. A recent study suggested that TP53, GNAS, and RAS mutation analysis could stratify tumors into distinct molecular groups with different prognosis.

Peritoneal carcinomatosis (PC) in gastric adenocarcinoma (GAC) is the most common metastatic site and leads to a short median survival. Exosomes have been shown to remodel the microenvironment, facilitating tumor metastases. However, the functional component in GAC cell-derived exosomes that remodel the landscape in the peritoneal cavity remains unclear.

Purpose: To compare clinicopathologic features and clinical outcomes of metastatic colorectal cancer (mCRC) based on EGFR amplification status.

Materials And Methods: Patients with mCRC who underwent next-generation sequencing using a targeted 244-gene panel from 2016 to 2021 were identified and screened for EGFR copy numbers. Cases with at least 5 copies were reviewed for tumor purity adjustment, and those with an adjusted copy number of ≥6 were defined as EGFR-amplified (EGFR amp+).

Background: Advanced gastric cancer (GC) exhibits a high recurrence rate and a dismal prognosis. Myocyte enhancer factor 2c (MEF2C) was found to contribute to the development of various types of cancer. Therefore, our aim is to develop a prognostic model that predicts the prognosis of GC patients and initially explore the role of MEF2C in immunotherapy for GC.

The necessity of prophylactic cytoreductive surgery (PCRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for low-grade appendiceal mucinous neoplasms (LAMN) after complete removal is still controversial. This study aims to determine the role of PCRS + HIPEC and identify optimal strategies for managing these patients. One hundred fifty-nine patients who sought medical advice at Aerospace Center Hospital were retrospectively analyzed from January 2011 to December 2021.
