Pancreatic surgery is associated with severe postoperative morbidity. Identification of patients at high risk may provide a way to allocate resources objectively and focus care on those patients in greater need. The Authors evaluate the prevalence of malnutrition and its effect on the postoperative morbidity of patients undergoing pancreatic surgery for malignant tumors. ⋯ Malnutrition is a relevant predictor of post-operative morbidity and mortality after pancreatic surgery. Patients underwent pancreatic resection for malignant tumors are usually malnourished. Preoperative malnutrition screening is mandatory in order to assess the risk and to treat the malnutrition.

Surgery in carcinoid patients can provoke a carcinoid crisis, which can have serious sequelae, including death. Octreotide prophylaxis is recommended to prevent carcinoid crisis, however there are few reports of outcomes and no large series examining its efficacy. We hypothesized that a 500 µg prophylactic octreotide dose is sufficient to prevent carcinoid crisis. ⋯ Significant intraoperative complications occur frequently in patients with hepatic metastases regardless of presence of carcinoid syndrome and despite octreotide LAR or single dose prophylactic octreotide. Occurrence of such events correlates strongly with postoperative complications. Randomized controlled trials are needed to determine whether the administration of prophylactic octreotide is beneficial.

CD44 and CD133 have been reported as putative stem cell markers. However, the clinicopathologic significance of CD44 and CD133 expression in patients with gastric carcinoma (GC) has not been clearly elucidated. ⋯ Our study introduces high expression of CD44 and CD133 as adverse independent prognostic factors in GC patients. The combined CD44 and CD133 expression may become a useful tool for identifying patients with different clinical outcomes.

Combined pancreatic and liver resection for hepato-pancreatico-biliary disease is generally considered contraindicated since it is thought to provide little if any survival benefit with high risk of morbidity. Our goal was to review our experience with combined pancreatic and liver resections to better define characteristics that increase risk for perioperative complications after combined resections. ⋯ Combined pancreas and liver resection for metastatic disease should only be considered in highly selected patients. Tumor histology as well as BMI > 25 (overweight and obese patients) should be considered in the decision making process in an effort to minimize surgical morbidity while potentially improving survival.

Adjuvant chemotherapy has been known as a standard treatment for patients with resected colon cancer. However, in elderly colon cancer patients, the characteristics of patients are heterogeneous with regard to life expectancy and comorbidities. Thus, with regard to the effectiveness of adjuvant chemotherapy for colon cancer, it is difficult to extrapolate data of clinical trials from the younger into the older general population. ⋯ Adjuvant chemotherapy for elderly patients with Stage II colon cancer is not effective, whereas elderly patients with Stage III with adjuvant chemotherapy appear to have a better survival rate in the general population.
