Pre-Surgical Nutrition Support Reduces the Incidence of Surgical Wound Complications in Oncological Patients.

Patients who suffer from cancer are at a higher risk of complications when they experience malnutrition. Evidence shows that oral nutritional supplements favor the healing process. The main objective of this study was to evaluate the efficacy of preoperative oral nutritional intervention in oncological patients undergoing surgery. This study assessed retrospectively 55 cancer patients who previously had undergone abdominal surgery and did not have receive pre-surgical nutritional support (control group), and prospectively 30 oncological patients undergoing gastrointestinal surgery and received pre-surgical high-protein nutritional support (experimental group). All patients had to have a NRS 2002 score ≥ 3. Analytical and clinical parameters were analyzed and the NRS 2002 screening test was performed. Post-operative assessments of surgical wound complications were also carried out to determine the impact of nutrition support. Pre-surgical nutritional interventions reduced the incidence and severity of wound complications as well as the length of hospital stays. Only 26.7% of patients in the experimental group had complications compared to 60% of the control group (P = 0.003). We conclude that pre-surgical nutritional interventions of patients undergoing surgery can improve post-surgical patient outcomes of malnourished patients.

Watch and wait approach in rectal cancer: Current controversies and future directions.

According to the main international clinical guidelines, the recommended treatment for locally-advanced rectal cancer is neoadjuvant chemoradiotherapy followed by surgery. However, doubts have been raised about the appropriate definition of clinical complete response (cCR) after neoadjuvant therapy and the role of surgery in patients who achieve a cCR. Surgical resection is associated with significant morbidity and decreased quality of life (QoL), which is especially relevant given the favourable prognosis in this patient subset. Accordingly, there has been a growing interest in alternative approaches with less morbidity, including the organ-preserving watch and wait strategy, in which surgery is omitted in patients who have achieved a cCR. These patients are managed with a specific follow-up protocol to ensure adequate cancer control, including the early identification of recurrent disease. However, there are several open questions about this strategy, including patient selection, the clinical and radiological criteria to accurately determine cCR, the duration of neoadjuvant treatment, the role of dose intensification (chemotherapy and/or radiotherapy), optimal follow-up protocols, and the future perspectives of this approach. In the present review, we summarize the available evidence on the watch and wait strategy in this clinical scenario, including ongoing clinical trials, QoL in these patients, and the controversies surrounding this treatment approach.
