Low grade appendiceal mucinous neoplasm: A single center experience in southern Taiwan

Advances in Digestive Medicine, Volume 13, Issue 2, June 2026.
Abstract Low grade appendiceal mucinous neoplasms (LAMN) were characterized by a villous or flat circumferential proliferation of mucinous epithelium with low grade atypia and lack of overtly malignant features and abundant mucin production. However, if left untreated and ruptured, LAMN can lead to intraperitoneal accumulation of gelatinous ascites and

Safety and Tolerability of Different Total Neoadjuvant Therapies in Patients With Locally Advanced Rectal Cancer

Cancer Medicine, Volume 15, Issue 6, June 2026.
ABSTRACT Background Total neoadjuvant therapy (TNT) is the standard treatment for locally advanced rectal cancer (LARC). Few studies have focused on the toxicity of TNT. Moreover, the differences in safety and tolerability between radiotherapy‐first and chemotherapy‐first strategies remain unclear.

Frequent GNAS mutations in low-grade appendiceal mucinous neoplasms [PDF]

British Journal of Cancer, 2013
The molecular basis for the development of appendiceal mucinous tumours, which can be a cause of pseudomyxoma peritonei, remains largely unknown.Thirty-five appendiceal mucinous neoplasms were analysed for GNAS and KRAS mutations. A functional analysis of mutant GNAS was performed using a colorectal cancer cell line.A mutational analysis identified ...
