Colorectal Adenocarcinoma

Brief summary

Compared to upper gastrointestinal (GI) malignancies, CRC patients generally present with satisfactory nutritional status at surgery and malnutrition is typically present in advanced stages of CRC. Therefore, in the latter surgery may not be offered with curative intent. Based on the current evidence, the role of OIN appears to be consolidated for malnourished patients undergoing surgery for gastrointestinal cancer. Regarding not malnourished patients, there is still no clear correlation between OIN and decrease in post-operative complications. Furthermore, whether OIN increases immune response within the tumour microenvironment is based on studies with poor number of patients.

Detailed description

Randomized, controlled, open-label, single-centre study in patients candidate for elective curative surgery for colon-rectal cancer. The study intervention consists of the oral nutritional supplementation enriched with immune-nutrients delivered before and after surgery in addition to standard dietary advice according to E.R.A.S. protocol. All patients will follow low-fiber diet according to ERAS protocol during the study period. Patients assigned to the experimental arm will assume also Impact Oral®, an oral nutritional supplement with immune-nutrients (hyper-proteic formula), manufactured and commercialized by Nestlé Health Science S.p.a. It is a liquid drink packaged in a brick of 237 ml. Patients will assume Impact Oral® for 5 days before surgery and 5 day after surgery.

Design outcomes

Primary

MeasureTime frameDescription
Primary Outcome Measure - Number of patients with grade 2 or higher post-operative complicationswithin 30 days post-surgical interventionNumber of patients with grade 2 or higher post-operative complications according to Clavien-Dindo classification occurred within 30 days post-surgical intervention.

Secondary

MeasureTime frameDescription
Secondary Outcome Measure - Hospital length of stayFrom the day of surgery until discharge, assessed up to 7 daysHospital length of stay defined as hospitalization from the day of surgery until discharge
Secondary Outcome Measure - Reoperation ratewithin 30 days following the index surgeryReoperation rate within 30 days from index surgery defined as any unplanned post-operative procedure including a return in the operating room or an imaging-guided intervention within 30 days following the index surgery
Secondary Outcome Measure - Unplanned readmissionswithin 30 days from dischargeUnplanned readmissions within 30 days from discharge
Secondary Outcome Measure - 30-day mortality for any cause30-day mortality for any cause30-day mortality for any cause
Secondary Outcome Measure - Safety assessed according to CTCAEFrom admission to discharge, assessed up to 42 daysSafety assessed according to criteria to NCI Common Toxicity Criteria Adverse Event (CTCAE), version 5
Secondary Outcome Measure - Nutritional status before and after surgerydifferences at day 1, 3, 5, 15 and 30 after surgery from T0 (7-10 days before surgery) will be calculated and compared between the two armsNutritional status before and after surgery will be assessed evaluating albumin, prealbumin and transferrin serum levels: differences at day 1, 3, 5, 15 and 30 after surgery from T0 (7-10 days before surgery) will be calculated and compared between the two arms
Secondary Outcome Measure - Inflammatory status before and after surgerydifferences at day 1, 3, 5, 15 and 30 after surgery from T0 (7-10 days before surgery) will be calculated and compared between the two armsInflammatory status before and after surgery will be assessed evaluating leukocytes (x10\^(9)/L), C-reactive protein (PCR) (mg/dL), procalcitonin (ug/L), neutrophil-lymphocyte (ratio), and lactate dehydrogenase (LDH) serum levels (U/L). The haematic quantification of this biomarkers provides information about the inflammatory status.
