Background: Complete mesocolic excision (CME) and a high (apical) vascular tie may improve oncologic outcome after surgery for colon cancer. Our primary aim was to emulate a previous national result of 73.8% overall survival (OS) with both the open and laparoscopic techniques.
Methods: A prospective study of radical colon cancer was initiated in a Norwegian community teaching hospital in 2007 and comprised a consecutive group of 251 patients with TNM stages I-III that had surgery according to the CME principle. Oncological outcome was assessed as OS, disease-free survival (DFS) and cancer-specific survival (CSS), as well as time to recurrence (TTR), using Cox regression analysis.
Results: In-hospital mortality was 3.6%, 2.3% for laparoscopic surgery and 4.9% for open management. Significantly more patients in the open CME group developed complications in the short term (p < 0.001). Twelve or more lymph nodes were retrieved from 82.9% (208/251) of the specimens. Overall 3-year OS was 84.5%, DFS 77.4%, CSS 91.5% and TTR 86.8%. The surgical approach was not a significant predictor for any of the survival parameters.
Conclusions: There was no survival difference between open and laparoscopic CME colonic resections, and the present OS improved from a previous OS from 2000.

Background: Studies have reported clinical heterogeneity between right-sided colon cancer (RCC) and left-sided colon cancer (LCC). However, none of these studies used multi-omics analysis combining genetic regulation, microbiota, and metabolites to explain the site-specific difference.
Methods: Here, 494 participants from a 16S rRNA gene sequencing cohort (50 RCC, 114 LCC, and 100 healthy controls) and a multi-omics cohort (63 RCC, 79 LCC, and 88 healthy controls) were analyzed.

Background: Sepsis represents the most prevalent infectious complication and the primary cause of mortality in myeloproliferative neoplasms (MPN). The risk of sepsis and the difficulty of treatment are significantly increased in MPN patients due to the need for immunomodulators and antibiotics.

Background: The Peritoneal Cancer Index (PCI), calculated intraoperatively, has previously yielded mixed results when correlated with computed tomography. This study aimed to quantify variation in this scoring method comparing radiologists' and surgeons' radiologic PCI (rPCI) assessment.
Methods: The rPCI of 104 patients treated at a single institution for peritoneal carcinomatosis was calculated by an abdominal radiologist and a surgeon.

The development of prophylactic cancer vaccines typically involves the selection of combinations of tumour-associated antigens, tumour-specific antigens and neoantigens. Here we show that membranes from induced pluripotent stem cells can serve as a tumour-antigen pool, and that a nanoparticle vaccine consisting of self-assembled commercial adjuvants wrapped by such membranes robustly stimulated innate immunity, evaded antigen-specific tolerance and activated B-cell and T-cell responses, which were mediated by epitopes from the abundant number of antigens shared between the membranes of tumour cells and pluripotent stem cells. In mice, the vaccine elicited systemic antitumour memory T-cell and B-cell responses as well as tumour-specific immune responses after a tumour challenge, and inhibited the progression of melanoma, colon cancer, breast cancer and post-operative lung metastases.
