Prehabilitation is a possible means of enhancing the physical condition of patients preoperatively. The quality of studies in older patients undergoing colorectal surgery is poor, despite the increase in elderly people with colorectal cancer. Defining specific patient groups at risk and standardizing the outcome are essential for improving the results of treatment.

Background Although self‐expandable metal stent (SEMS) placement as bridge to surgery (BTS) in patients with left‐sided obstructing colonic cancer has shown promising short‐term results, it is used infrequently owing to uncertainty about its oncological safety. This population study compared long‐term oncological outcomes between emergency resection and SEMS placement as BTS. Methods Through a national collaborative research project, long‐term outcome data were collected for all patients who underwent resection for left‐sided obstructing colonic cancer between 2009 and 2016 in 75 Dutch hospitals. Patients were identified from the Dutch Colorectal Audit database. SEMS as BTS was compared with emergency resection in the curative setting after 1 : 2 propensity score matching. Results Some 222 patients who had a stent placed were matched to 444 who underwent emergency resection. The overall SEMS‐related perforation rate was 7·7 per cent (17 of 222). Three‐year locoregional recurrence rates after SEMS insertion and emergency resection were 11·4 and 13·6 per cent (P = 0·457), disease‐free survival rates were 58·8 and 52·6 per cent (P = 0·175), and overall survival rates were 74·0 and 68·3 per cent (P = 0·231), respectively. SEMS placement resulted in significantly fewer permanent stomas (23·9 versus 45·3 per cent; P < 0·001), especially in elderly patients (29·0 versus 57·9 per cent; P < 0·001). For patients in the SEMS group with or without perforation, 3‐year locoregional recurrence rates were 18 and 11·0 per cent (P = 0·432), disease‐free survival rates were 49 and 59·6 per cent (P = 0·717), and overall survival rates 61 and 75·1 per cent (P = 0·529), respectively. Conclusion Overall, SEMS as BTS seems an oncologically safe alternative to emergency resection with fewer permanent stomas. Nevertheless, the risk of SEMS‐related perforation, as well as permanent stoma, might influence shared decision‐making for individual patients.

Objective The preoperative phase is a potential window of opportunity. Although frail elderly patients are known to be more prone to postoperative complications, they are often not considered capable of accomplishing a full prehabilitation program. The aim of this study was to assess the feasibility of Fit4SurgeryTV, an athome prehabilitation program specifically designed for frail elderly with colorectal cancer (CRC). Design The Fit4SurgeryTV program consisted of a daily elderly-adapted computer-supported strength training workout and two protein-rich meals. Frail patients 70 years with CRC were included. The program was considered feasible if 80% of the patients would be able to complete 70% of the program. Results Fourteen patients (median age 79, 5 males) participated. At baseline, 86% patients were physically impaired and 64% were at risk for malnourishment. Median duration of the program was 26 days. The program was feasible as patients followed the exercises for 6/7 (86%) days and prepared the recipes 5/7 (71%) days per week. Patients specifically appreciated at-home exercises. Conclusion This study showed that at-home prehabilitation in frail elderly with CRC is feasible. As a result, patients might be fitter for surgery and might recover faster. The perioperative period could serve as a pivotal time point in reverting complications of immobility.

Implementation of IV iron therapy in anemic colorectal cancer patients leads to a distinct increase of preoperative Hb level. IV iron therapy is most effective in patients presenting with more severe anemia, and with higher transferrin and lower ferritin levels, markers for an absolute iron deficiency (ID), compared to functional ID.

Current studies are too heterogeneous to conclude that pre-operative oral nutritional support could enhance the condition of patients undergoing colorectal surgery. Patients at risk have a relatively lean body mass deficit (sarcopenia) rather than an absolute malnourished status. Compliance is an important element of prehabilitation. Targeting patients at risk, combining protein supplements with strength training, and defining standardized patient-related outcomes will be essential to obtain satisfactory results.

BACKGROUND:There is still controversy about the relationship between preoperative anemia and outcomes after rectal cancer surgery. OBJECTIVE:The aim of this study was to analyze the association between preoperative anemia and postoperative complications and the survival of patients undergoing surgery for rectal cancer in the era of laparoscopic surgery and modern perioperative care. DESIGN:This was a cohort study. SETTINGS: Data were gathered from 71 hospitals in The Netherlands.PATIENTS: Patients who underwent resection for rectal cancer in 2011, for whom preoperative hemoglobin level was registered, were included. INTERVENTIONS(S): There were no interventions.MAIN OUTCOME MEASURES: Short-term outcome parameters were any postoperative complication or mortality within 30 days postoperatively, and pelvic infectious complications defined as anastomotic leakage and presacral abscess. Long-term outcomes were chronic sinus diagnosed at any time during 3-year follow-up, 3-year local and distant recurrence rates, and 3-year overall survival. RESULTS:Of 2095 patients, 1857 had a registered preoperative hemoglobin level; 576 (31%) of these patients anemic and 1281 (69%) were nonanemic. Preoperative anemia was not independently associated with postoperative complications (HR, 1.1; 95% CI, 0.9-1.4; p = 0•24) or 30-day mortality (HR, 1.4, 95% CI, 0.7-2.8; p = 0•29). Preoperative anemia was associated with 3-year overall survival (HR, 2.1; 95% CI, 1.7-2.5; p < 0.0001), after multivariable analysis (HR, 1.4; 95% CI, 1.1-1.8; p = 0•008), and with local recurrence rate (HR, 1.6; 95% CI, 1.1-2.4; p = 0.026), but not with distant recurrence rate (HR, 1.2; 95% CI, 1.0-1.5; p = 0.054). LIMITATIONS:Preoperative anemia appeared to have only limited association with postoperative and disease-specific outcome after rectal cancer surgery in contrast to published meta-analysis of small historical series.CONCLUSIONS: Anemia is associated with overall survival. It might be considered as one of the warning signs in identifying high-risk patients. See Video Abstract at http://links.lww.com/DCR/A913.
