Perioperative chemotherapy with FOLFOX4 and surgery versus surgery alone for resectable liver metastases from colorectal cancer (EORTC Intergroup trial 40983): a randomised controlled trial

B. Nordlinger, H. Sørbye, B. Glimelius et al.

Summary Background Surgical resection alone is regarded as the standard of care for patients with liver metastases from colorectal cancer, but relapse is common. We assessed the combination of perioperative chemotherapy and surgery compared with surgery alone for patients with initially resectable liver metastases from colorectal cancer. Methods This parallel-group study reports the trial's final data for progression-free survival for a protocol unspecified interim time-point, while overall survival is still being monitored. 364 patients with histologically proven colorectal cancer and up to four liver metastases were randomly assigned to either six cycles of FOLFOX4 before and six cycles after surgery or to surgery alone (182 in perioperative chemotherapy group vs 182 in surgery group). Patients were centrally randomised by minimisation, adjusting for centre and risk score. The primary objective was to detect a hazard ratio (HR) of 0·71 or less for progression-free survival. Primary analysis was by intention to treat. Analyses were repeated for all eligible (171 vs 171) and resected patients (151 vs 152). This trial is registered with ClinicalTrials.gov, number NCT00006479. Findings In the perioperative chemotherapy group, 151 (83%) patients were resected after a median of six (range 1–6) preoperative cycles and 115 (63%) patients received a median six (1–8) postoperative cycles. 152 (84%) patients were resected in the surgery group. The absolute increase in rate of progression-free survival at 3 years was 7·3% (from 28·1% [95·66% CI 21·3–35·5] to 35·4% [28·1–42·7]; HR 0·79 [0·62–1·02]; p=0·058) in randomised patients; 8·1% (from 28·1% [21·2–36·6] to 36·2% [28·7–43·8]; HR 0·77 [0·60–1·00]; p=0·041) in eligible patients; and 9·2% (from 33·2% [25·3–41·2] to 42·4% [34·0–50·5]; HR 0·73 [0·55–0·97]; p=0·025) in patients undergoing resection. 139 patients died (64 in perioperative chemotherapy group vs 75 in surgery group). Reversible postoperative complications occurred more often after chemotherapy than after surgery (40/159 [25%] vs 27/170 [16%]; p=0·04). After surgery we recorded two deaths in the surgery alone group and one in the perioperative chemotherapy group. Interpretation Perioperative chemotherapy with FOLFOX4 is compatible with major liver surgery and reduces the risk of events of progression-free survival in eligible and resected patients.

Effect of Exercise and Nutrition Prehabilitation on Functional Capacity in Esophagogastric Cancer Surgery: A Randomized Clinical Trial

E. Minnella, Rashami Awasthi, S. Loiselle et al.

Importance Preserving functional capacity is a key element in the care continuum for patients with esophagogastric cancer. Prehabilitation, a preoperative conditioning intervention aiming to optimize physical status, has not been tested in upper gastrointestinal surgery to date. Objective To investigate whether prehabilitation is effective in improving functional status in patients undergoing esophagogastric cancer resection. Design, Setting, and Participants A randomized clinical trial (available-case analysis based on completed assessments) was conducted at McGill University Health Centre (Montreal, Quebec, Canada) comparing prehabilitation with a control group. Intervention consisted of preoperative exercise and nutrition optimization. Participants were adults awaiting elective esophagogastric resection for cancer. The study dates were February 13, 2013, to February 10, 2017. Main Outcomes and Measures The primary outcome was change in functional capacity, measured with absolute change in 6-minute walk distance (6MWD). Preoperative (end of the prehabilitation period) and postoperative (from 4 to 8 weeks after surgery) data were compared between groups. Results Sixty-eight patients were randomized, and 51 were included in the primary analysis. The control group were a mean (SD) age, 68.0 (11.6) years and 20 (80%) men. Patients in the prehabilitation group were a mean (SD) age, 67.3 (7.4) years and 18 (69%) men. Compared with the control group, the prehabilitation group had improved functional capacity both before surgery (mean [SD] 6MWD change, 36.9 [51.4] vs −22.8 [52.5] m; P < .001) and after surgery (mean [SD] 6MWD change, 15.4 [65.6] vs −81.8 [87.0] m; P < .001). Conclusions and Relevance Prehabilitation improves perioperative functional capacity in esophagogastric surgery. Keeping patients from physical and nutritional status decline could have a significant effect on the cancer care continuum. Trial Registration ClinicalTrials.gov Identifier: NCT01666158

Association Between Use of Enhanced Recovery After Surgery Protocol and Postoperative Complications in Colorectal Surgery: The Postoperative Outcomes Within Enhanced Recovery After Surgery Protocol (POWER) Study.

J. Ripollés-Melchor, J. Ramírez-Rodríguez, R. Casans-Francés et al.

Importance Enhanced Recovery After Surgery (ERAS) care has been reported to be associated with improvements in outcomes after colorectal surgery compared with traditional care. Objective To determine the association between ERAS protocols and outcomes in patients undergoing elective colorectal surgery. Design, Setting, and Participants The Postoperative Outcomes Within Enhanced Recovery After Surgery Protocol (POWER) Study is a multicenter, prospective cohort study of 2084 consecutive adults scheduled for elective colorectal surgery who received or did not receive care in a self-declared ERAS center. Patients were recruited from 80 Spanish centers between September 15 and December 15, 2017. All patients included in this analysis had 1 month of follow-up. Exposures Colorectal surgery and perioperative management were the exposures. Twenty-two individual ERAS items were assessed in all patients, regardless of whether they were included in an established ERAS protocol. Main Outcomes and Measures The primary study outcome was moderate to severe postoperative complications within 30 days after surgery. Secondary outcomes included ERAS adherence, mortality, readmissions, reoperation rates, and hospital length of stay. Results Between September 15 and December 15, 2017, 2084 patients were included in the study. Of these, 1286 individuals (61.7%) were men; mean age was 68 years (interquartile range [IQR], 59-77). A total of 879 patients (42.2%) presented with postoperative complications and 566 patients (27.2%) developed moderate to severe complications. The number of patients with moderate or severe complications was lower in the ERAS group (25.2% vs 30.3%; odds ratio [OR], 0.77; 95% CI, 0.63-0.94; P = .01). The overall rate of adherence to the ERAS protocol was 63.6% (IQR, 54.5%-77.3%), and the rate for patients from hospitals self-declared as ERAS was 72.7% (IQR, 59.1%-81.8%) vs non-ERAS institutions, which was 59.1% (IQR, 50.0%-63.6%; P < .001). Adherence quartiles among patients receiving the highest and lowest ERAS components showed that the patients with the highest adherence rates had fewer moderate to severe complications (OR, 0.34; 95% CI, 0.25-0.46; P < .001), overall complications (OR, 0.33; 95% CI, 0.26-0.43; P < .001), and mortality (OR, 0.27; 95% CI, 0.07-0.97; P = .06) compared with those who had the lowest adherence rates. Conclusions and Relevance An increase in ERAS adherence appears to be associated with a decrease in postoperative complications.

Consensus Guidelines for the Use of Fluorescence Imaging in Hepatobiliary Surgery.

Xiaoying Wang, C. Teh, T. Ishizawa et al.

OBJECTIVE To establish consensus recommendations for the use of fluorescence imaging with indocyanine green (ICG) in hepatobiliary surgery. BACKGROUND ICG fluorescence imaging has gained popularity in hepatobiliary surgery in recent years. However, there is varied evidence on the use, dosage, and timing of administration of ICG in clinical practice. To standardize the use of this imaging modality in hepatobiliary surgery, a panel of pioneering experts from the Asia-Pacific region sought to establish a set of consensus recommendations by consolidating the available evidence and clinical experiences. METHODS A total of 13 surgeons experienced in hepatobiliary surgery and/or minimally invasive surgery formed an expert consensus panel in Shanghai, China in October 2018. By the modified Delphi method, they presented the relevant evidence, discussed clinical experiences, and derived consensus statements on the use of ICG in hepatobiliary surgery. Each statement was discussed and modified until a unanimous consensus was achieved. RESULTS A total of 7 recommendations for the clinical applications of ICG in hepatobiliary surgery were formulated. CONCLUSIONS The Shanghai consensus recommendations offer practical tips and techniques to augment the safety and technical feasibility of ICG fluorescence-guided hepatobiliary surgery, including laparoscopic cholecystectomy, liver segmentectomy, and liver transplantation.

Clinical Outcomes of Robotic Surgery Compared to Conventional Surgical Approaches (Laparoscopic or Open)

H. Muaddi, Mélanie El Hafid, W. Choi et al.

Supplemental Digital Content is available in the text Objective: Describe clinical outcomes (eg, postoperative complications, survival) after robotic surgery compared to open or laparoscopic surgery. Background: Robotic surgery utilization has increased over the years across a wide range of surgical procedures. However, evidence supporting improved clinical outcomes after robotic surgery is limited. Methods: We systematically searched MEDLINE, EMBASE, and the Cochrane Central Register of systematic reviews from inception to January 2019 for systematic reviews describing postoperative outcomes after robotic surgery. We qualitatively described patient outcomes of commonly performed robotic procedures: radical prostatectomy, hysterectomy, lobectomy, thymectomy, rectal resection, partial nephrectomy, distal gastrectomy, Roux-en-Y gastric bypass, hepatectomy, distal pancreatectomy, and cholecystectomy. Results: One hundred fifty-four systematic reviews included 336 studies and 18 randomized controlled trials reporting on patient outcomes after robotic compared to laparoscopic or open procedures. Data from the randomized controlled trials demonstrate that robotic-assisted radical prostatectomy offered fewer biochemical recurrence and improvement in quality of recovery and pain scores only up to 6 weeks postoperatively compared to open radical prostatectomy. When compared to laparoscopic prostatectomy, robotic surgery offered improved urinary and sexual functions. Robotic surgery for endometrial cancer had fewer conversion to open compared to laparoscopic. Otherwise, robotic surgery outcomes were similar to conventional surgical approaches for other procedures except for radical hysterectomy where minimally invasive approaches may result in patient harm compared to open approach. Conclusion: Robotic surgery has been widely incorporated into practise despite limited supporting evidence. More rigorous research focused on patient-important benefits is needed before further expansion of robotic surgery.
