Research suggests that TLRs may also have a significant impact on the development and progression of cancers, including gastric cancer (GC). Understanding the role of individual TLRs in the immunopathogenesis of gastric cancer may provide new information necessary to develop more effective diagnostic and therapeutic methods.

Navigating through novelties concerning mCRC treatment-the role of immunotherapy, chemotherapy, and targeted therapy in mCRC.

Over the course of nearly six decades since the inception of initial trials involving 5-FU in the treatment of mCRC (metastatic colorectal cancer), our progressive comprehension of the pathophysiology, genetics, and surgical techniques related to mCRC has paved the way for the introduction of novel therapeutic modalities. These advancements not only have augmented the overall survival but have also positively impacted the quality of life (QoL) for affected individuals.

Sexual activity in patients after proctocolectomy with ileal pouch-anal anastomosis.

<b>Introduction:</b> Proctocolectomy with ileal pouch-anal anastomosis is the gold standard in the surgical treatment of patients with ulcerative colitis, familial adenomatous polyposis and other colorectal diseases requiring colectomy. The treatment consists in removing the large intestine and creating an intestinal reservoir from the last ileum loop and then anastomosing the intestinal reservoir with the anal canal. Like any surgical procedure, RPC-IPAA also carries the risk of complications, both early and late.
