Changing patterns of multidisciplinary team treatment, early mortality, and survival in colorectal cancer.

BACKGROUND: This study reports early mortality and survival from colorectal cancer in relation to the pattern of treatments delivered by the multidisciplinary team (MDT) meeting at a high-volume institution in England over 14 years. METHODS: All patients diagnosed with colorectal cancer and discussed during MDT meetings from 2003 to 2016 at a single institution were reviewed. Three time intervals (2003-2007, 2008-2012, and 2013-2016) were compared regarding initial surgical management (resection, local excision, non-resection surgery, and no surgery), initial oncological therapy, 90-day mortality, and crude 2-year survival for the whole cohort. Sub-analyses were performed according to age greater or less than 80 years. RESULTS: The MDT managed 4617 patients over 14 years (1496 in the first interval and 1389 in the last). Over this time, there was a reduction in emergency resections from 15.5 per cent to 9.0 per cent (P < 0.0001); use of oncological therapies increased from 34.6 per cent to 41.6 per cent (P < 0.0001). The 90-day mortality after diagnosis of colorectal cancer dropped from 14.8 per cent to 10.7 per cent (P < 0.001) and 2-year survival improved from 58.6 per cent to 65 per cent (P < 0.001). Among patients aged 80 years or older (425 and 446, in the first and last intervals respectively) there was, in addition, a progressive increase in 'no surgery' rate from 33.6 per cent to 50.2 per cent (P < 0.0001) and a reduction in elective resections from 42.4 per cent to 33.9 per cent (P = 0.010). The 90-day mortality after elective resection fell from 10.0 per cent (18 of 180) to 3.3 per cent (5 of 151; P = 0.013). CONCLUSIONS: Survival from colorectal cancer improved significantly over 14 years. Among patients aged ≥80 years, major changes in the type of treatment delivered were associated with a decrease in postoperative mortality.

Modular training in laparoscopic colorectal surgery maximizes training opportunities without clinical compromise.

BACKGROUND: Laparoscopic surgery is increasingly proposed as the gold standard technique for colorectal resections and is offered to greater numbers of patients. To meet the rising service demands, more trainees and established consultants need to learn the technique. We sought to establish whether it is feasible and safe to train on a large proportion of patients without adversely affecting clinical outcome or smooth running of clinical service. METHODS: Between September 2006 and July 2008, four senior trainees of the Wessex Specialist Registrar training rotation were involved in training in laparoscopic colorectal surgery. Major colorectal resections were separated into clearly defined modules for training purposes. Right and left hemicolectomies each comprised two modules, and low anterior resection comprised three modules. Prospective data on consecutive patients undergoing laparoscopic colorectal surgery were collected. Data included type of surgery, module of procedure performed by trainee or trainer, body mass index (BMI), conversion rates, median operative time, complications, length of hospital stay, and mortality. RESULTS: During the study period 227 colorectal resections were attempted laparoscopically. Of these, 216 (96%) proved suitable for training and 97% were completed laparoscopically. Some 23% of patients were American Society of Anesthesiologists score (ASA)≥3; 35% had a BMI≥28; 38% had a history of previous laparotomy. Trainees performed 96% (142/148) of right hemicolectomy modules, 99% (154/156) of left hemicolectomy modules, and 67% (128/192) of rectal resection modules. Each trainee was competent to do right and left hemicolectomy at the end of the training period. Four patients (2%) required further surgery for postoperative complications. Of the procedures completed by the trainees, 155/171 (91%) cancer resections were potentially surgically curative, and R0 resections were achieved in 99%. The readmission rate was 10% (22/216) and median length of hospital stay was 4 days. Postoperative mortality was zero. CONCLUSIONS: Using a modular approach it is possible to provide effective training during almost all laparoscopic colorectal resections while achieving good clinical outcomes for the patients.

Laparoscopic colorectal surgery produces better outcomes for high risk cancer patients compared to open surgery.

BACKGROUND AND OBJECTIVES: The excellent outcomes reported for laparoscopic colorectal surgery in selected patients could also be potentially advantageous for high risk patients. This prospective study was designed to examine the feasibility and safety of laparoscopic resection in high risk patients with colorectal cancer. METHODS: Between 2006 and 2008 consecutive patients undergoing elective surgery for colorectal cancer were stratified into high and low risk groups. High risk was defined as >or=80 years, American Society of Anesthesiologists >or=3, preoperative radiotherapy, T4 tumor and BMI >or=30. Outcomes included median length of stay, lymph node yield, resection margins, 30-day hospital readmission, postoperative mortality and major postoperative complications requiring reoperation within 30 days of surgery. RESULTS: A total of 424 patients underwent elective laparoscopic (224) and open (200) resections. Overall mortality rate for laparoscopic resection was 1 of 224 (0.4%) versus 4 of 200 (2%) for open resection. Median length of stay was 4 (2-33) versus 10 (1-69) days (P < 0.0001), and rate of complications requiring reoperation was 2 of 224 (0.8%) compared with 10 of 200 (5%) (P = 0.02).Among the 280 (66%) "high risk" patients, 146 had laparoscopic resection (8 conversions; 5%) and 134 had open resections. Median hospital stay was 4 (2-33) days in the laparoscopic group versus 11 (1-69) days in the open group (P < 0.0001). Complications requiring reoperation were 2 of 146 (1.4%) after laparoscopic resection versus 7 of 134 (5.2%) after open resection (P < 0.09). Readmission rate after laparoscopic resection was 12.3% versus 5.2% after open resection (P = 0.06). CONCLUSION: Laparoscopic resection of colorectal cancer can achieve excellent results even in "high risk" patients and is associated with significant reductions in length of stay compared with open resection.
