Colorectal cancer (CRC) is a significant public health problem. There is increasing evidence that the host’s immune response and nutritional status play a role in the development and progression of cancer. The aim of our study was to examine the prognostic value of clinical markers/indexes of inflammation, nutritional and pathohistological status in relation to overall survival and disease free-survival in CRC. The total number of CRC patients included in the study was 111 and they underwent laboratory analyses within a week before surgery. Detailed pathohistological analysis and laboratory parameters were part of the standard hospital pre-operative procedure. Medical data were collected from archived hospital data. Data on the exact date of death were obtained by inspecting the death registers for the territory of the Republic of Serbia. All parameters were analyzed in relation to the overall survival and survival period without disease relapse. The follow-up median was 42 (24−48) months. The patients with the III, IV and V degrees of the Clavien–Dindo classification had 2.609 (HR: 2.609; 95% CI: 1.437−4.737; p = 0.002) times higher risk of death. The modified Glasgow prognostic score (mGPS) 2 and higher lymph node ratio carried a 2.188 (HR: 2.188; 95% CI: 1.413−3.387; p < 0.001) and 6.862 (HR: 6.862; 95% CI: 1.635−28.808; p = 0.009) times higher risk of death in the postoperative period, respectively; the risk was 3.089 times higher (HR: 3.089; 95% CI: 1.447−6.593; p = 0.004) in patients with verified tumor deposits. The patients with tumor deposits had 1.888 (HR: 1.888; 95% CI: 1024−3481; p = 0.042) and 3.049 (HR: 3.049; 95% CI: 1.206−7.706; p = 0.018) times higher risk of disease recurrence, respectively. The emphasized peritumoral lymphocyte response reduced the risk of recurrence by 61% (HR: 0.391; 95% CI: 0.196−0.780; p = 0.005). Standard perioperative laboratory and pathohistological parameters, which do not present any additional cost for the health system, may provide information on the CRC patient outcome and lay the groundwork for a larger prospective examination. © 2023 by the authors.

Introduction/Objective Nutritional status is related to the prognosis of colorectal cancer (CRC) patients. The CONUT (The Controlling Nutritional Status) score is a recent nutritional marker. This study aimed to examine the association of preoperative CONUT score with overall survival (OS) and disease-free survival (DFS), while the secondary aim was to assess the importance of preoperative nutritional status for the development of postoperative complications. The total number of CRC patients included in the study was 111. All patients underwent laboratory analyses within a week before surgery. Medical data were collected from archived data at the Zvezdara University Medical Centre. The CONUT score was analyzed in relation to the OS and DFS. Using the Kaplan-Meier survival curve and Log-rank test, a statistically significant difference in OS and DFS between groups of patients with different CONUT scores was observed. Patients with higher CONUT scores have a longer duration of hospitalization after surgery, a longer total length of stay, and a more severe degree of postoperative complications. The CONUT score is related to short-term treatment outcomes, such as the length of intrahospital treatment and frequency and severity of postoperative complications, but also to long-term prognostic parameters. Early nutritional screening may be of prognostic significance. © 2023 Editura Celsius. All rights reserved.

Pancreatectomies with arterial resections were initially characterized by high postoperative mortality and poor long-term survival as reported by Fortner et al. and then abandoned. The introduction of new efficacious chemotherapy regimens (FOLFIRINOX) along with the extensive experience in venous resection for borderline pancreatic tumors has brought renewed interest in extended pancreatic resection for locally advanced malignancy. The experience needed for performing such complex resections goes beyond pancreatic surgery alone and entails skills in vascular surgery. Reconstructing arterial vessels might need autologous and/or heterologous vascular substitutes which should be available immediately and accurate preoperative planning and simulation on the basis of cross-sectional imaging should be the rule. Resection of the superior mesenteric artery could be seen as one of the most challenging arterial resection at the time of pancreatectomy because of: (1) the frequent presence of an associated venous invasion; (2) the variable degree of tumoral infiltration downward through the mesentery; (3) the necessity of a mesenteric approach and complete mesenteric dissection; (4) the need for reconstructing several jejunal and ileal branches; (5) the high mortality rates (20%) reported so far. In this chapter we will describe step-by-step the surgical technique of our standardized approach for superior mesenteric artery resection during pancreaticoduodenectomy. © International Association of Surgeons, Gastroenterologists and Oncologists 2022.
