Abstract This study assessed the impact of postoperative complications on colorectal cancer survival and recurrence after curative surgery using pooled individual patients’ data from three large phase III randomized trials. In total, 5530 patients were included in this study. The classified as those with (C group) without ( NC group). risk factors for overall OS ) disease‐free DFS analyzed. Postoperative found 861 (15.6%) patients. rates at 5 years 68.9% 74.8%, respectively, C group 75.8%...

Objectives. To characterize body composition phenotypes using a dual-energy X-ray absorptiometry (DXA) method and to explore factors potentially contributing alterations in Vietnamese women with early RA. Methods. A total of 105 RA (disease duration ≤3 years) age-matched healthy underwent physical examination, regional lean mass (LM) fat (FM) DXA. The 28-joint DAS (DAS-28) disability HAQ score, nutrition, activity medications were recorded. Results. Means weight BMI similar patients...

The phase III ACHIEVE trial conducted in Japan was one of six prospective studies included the International Duration Evaluation Adjuvant Therapy collaboration, which explored whether 3 months adjuvant fluorouracil, leucovorin, and oxaliplatin (FOLFOX) or capecitabine (CAPOX) therapy would be noninferior to 6 treatment patients with curatively resected stage colon cancer. We report final analyses survival long-term safety.Eligible were randomly assigned (1:1) either chemotherapy (modified...

Differences in oncological outcomes between conservative and surgical treatments for anastomotic leakage (AL) patients undergoing colorectal cancer surgery remain unclear. From July 2011 to June 2020, 385 underwent curative resection with double-stapling anastomosis left-sided colon rectal cancers. Among them, 33 who experienced AL were retrospectively evaluated categorized into two groups: (n = 20) 13). In the group, abdominal lavage using a sufficient amount of normal saline was performed...

Monoclonal antibody mAbA33 recognizes a unique cell surface protein of colorectal cancer, the A33 antigen. Phase I/II studies have shown highly selective targeting radio-labeled in patients with metastatic opening up possibility A33-directed therapy. To better understand basis patients, present study was designed to define distribution normal organs and examine expression broad range tumor types. Immunohistochemical analysis tissues identified large small intestinal mucosa as principal sites...

A panel of 7 mouse monoclonal antibodies and the lectin from Ulex europeus, detecting blood-group-related antigens ABH Lewis systems, have been used to define distribution these antigenic structures within human gastrointestinal tract, characterize their expression modulation in colorectal carcinomas. The reagents employed detect following blood-group specificities: (all variants), B, H (type 2), Lewisa, Lewisb, X (Lewisx), Y (Lewisy) type 1 precursor chain. Immunohistochemical studies...

Preoperative serum levels of carcinoembryonic antigen (CEA) and/or carbohydrate 19.9 (CA19.9) were measured in 90 patients with advanced pancreatic cancer. CEA was above the cutoff 5.0 ng/ml 51% and CA19.9 limit 37 U/ml 87% patients. High preoperative related to a poor prognosis In multivariate analysis, hazard rate significantly higher high-CEA group (>2.5 ng/ml) compared low-CEA (<2.4 mg/ml). An increase within 1 month after operation also rate. This study reconfirms prognostic importance...
