AIM: to evaluate late results for patients that had open and laparoscopic total mesorectumectomy (TME) surgery for rectal cancer. PATIENTS AND METHODS: prospective cohort study included 103 patients aged from 20 to 70 years with rectal cancer. Patients were divided into 2 groups: the 1st group included 47 patients after laparoscopic TME (LTME) and the 2nd group included 56 patients after open one (OTME). All tumors were adenocarcinomas. Late results were assessed by actual and disease-free 3- and 5-year survival in 97 (94.2%) patients. RESULTS: local recurrence rate after OTME and LTME was 11,5% (6 patients) and 11,1% (5 patients) (p>0.05). Distant metastases occurred in 4 (7,7%) and 3 (6,7%) cases, respectively (p>0.05). The actual survival after LTME was 80.0% (81.8% after OTME, p>0.05), the disease-free 3-year survival rate was 56,7% (60.6% after OTME, p>0.05), 5-year survival was 31.6% (31.8% after OTME, p>0.05). CONCLUSION: no significant differences were found between laparoscopic and open approach for rectal cancer in local recurrence rate and survival.

Abstract Background Radical resection is associated with good prognosis among patients with cT1/T2Nx rectal cancer. However, still some of the patients experienced cancer recurrence following radical resection. This study tried to identify the postoperative risk factors of local recurrence and distant metastasis separately. Methods This retrospective, single-center study comprised of 279 consecutive patients from Linkou branch of Chang Gung Memorial Hospital in 2005–2016 with rectal adenocarcinoma, pT1/T2N0M0 at distance from anal verge ≤ 8cm, who received curative radical resection. Results The study included 279 patients with pT1/pT2N0 mid-low rectal cancer with median follow-up of 73.5 months. Nineteen (6.8%) patients had disease recurrence in total. Nine (3.2%) of them had local recurrence, and fourteen (5.0%) of them had distant metastasis. Distal resection margin < 0.9 (cm) (hazard ratio = 4.9, p = 0.050) was the risk factor of local recurrence. Preoperative carcinoembryonic antigen (CEA) ≥ 5 ng/mL (hazard ratio = 9.3, p = 0.0003), lymph node yield (LNY) < 14 (hazard ratio = 5.0, p = 0.006), and distal resection margin < 1.4cm (hazard ratio = 4.0, p = 0.035) were the risk factors of distant metastasis. Conclusion For patients with pT1/pT2N0 mid-low rectal cancer, current multidisciplinary treatment brings acceptable survival outcome. Insufficient distal resection margin attracted the awareness of risk factors for local recurrence and distant metastasis as a foundation for future research.

Anal Preservation

AbstractThe evolution over the past 20 years of anal preservation in rectal cancer surgery has been truly remarkable. Intersphincteric resection (ISR) reported by Schiessel in 1994 in Australia has been shown to enable anal preservation even for cancers quite close to the anus. In Japan, ISR via the detachment of the anal canal between the internal and external sphincters and excision of the internal sphincter first began to be practiced in the latter half of 1990. A multicenter Phase II trial of ISR in Japan suggested that 70% of the cases had relatively good function with less than 10 points of Wexner score but around 10% had severe incontinence that would not be improved for long term. The primary end point of the clinical study, 3-year local recurrence rate, was 13.2% across the overall cohort (T1, 0%; T2, 6.9%; and T3, 21.6%). When ISR is performed on T1/T2 rectal cancers, sufficient circumferential resection margin can be obtained even without preoperative chemoradiotherapy, and local recurrence rate was acceptably low. Based on these evidences, ISR is a currently important, standard treatment option among anal-preserving surgeries for T1/T2 low-lying rectal cancers. In Japan, a feasibility study (LapRC trial) of laparoscopic ISR on Stage 0 and Stage 1 low rectal cancer showed excellent outcomes. A prospective Phase II clinical trial targeting low rectal cancers within 5 cm from the anal verge (ultimate trial) is being performed and awaiting the results in near future.
