may be a source of marine natural products (MNPs) due to the antioxidant and antitumor activity of its crude homogenates shown in vitro in colon cancer cells. A bioguided chromatographic fractionation assay of crude homogenates with and without its symbiont was performed to characterize their bioactive composition and further determine their biological potential for the management of colorectal cancer (CRC). The 20% fractions retained the in vitro antioxidant activity previously reported for homogenates. As such, activation of antioxidant and detoxifying enzymes was also evaluated. The 40% fractions showed the greatest antiproliferative activity in T84 cells, synergistic effects with 5-fluoruracil and oxaliplatin, overexpression of apoptosis-related proteins, cytotoxicity on tumorspheres, and antiangiogenic activity. The predominantly polar lipids and toxins tentatively identified in the 20% and 40% fractions could be related to their biological activity in colon cancer cells although further characterizations of the active fractions are necessary to isolate and purify the bioactive compounds.

Objective: Splenectomy is regularly performed in total and distal pancreatectomy due to technical reasons, lymph node dissection and radicality of the operation. However, the spleen serves as an important organ for competent immune function, and its removal is associated with an increased incidence of cancer and a worse outcome in some cancer entities (Haematologica 99:392-398, 2014; Dis Colon Rectum 51:213-217, 2008; Dis Esophagus 21:334-339, 2008). The impact of splenectomy in pancreatic cancer is not fully resolved (J Am Coll Surg 188:516-521, 1999; J Surg Oncol 119:784-793, 2019).

Considering the high degree of malignancy, recurrence rate and poor prognosis, exploring promising targets is an imperious strategy for colorectal carcinoma therapy. Recent studies have indicated that GABPα plays a role in cancer aggressiveness, but its exact function and regulatory mechanisms in colorectal cancer progression remain unclear. This study aims to explore the biological role of GABPα and its upstream regulator, miR-378a-5p, in modulating cancer progression.

Background And Objective: Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Despite advances in treatment, metastatic colorectal cancer (mCRC) remains a significant challenge due to its heterogeneity and resistance to therapy. Regorafenib, a multikinase inhibitor, can inhibit tumor progression through multiple mechanisms, thereby improving patient prognosis.

Purpose: Endoscopic resection is appropriate for selected colorectal polyp cancers, but significant variation exists in treatment. This study aims to investigate variation in management of screen-detected polyp cancers (T1), factors predicting primary endoscopic polypectomy and threshold for subsequent surgical resection.

Method: Patients with polyp cancers (T1) diagnosed by the bowel cancer screening programme (BCSP) were investigated at two screening centres (5 individual sites and 4 MDTs, 2012-2022).
