Abstract Introduction: Laparoscopic surgery for rectal cancer has showed many advantages. Adjuvant chemotherapy can improve local recurrence, metastasis and survival. Materials and Methods: We reviewed rectal cancer patients who underwent laparoscopic rectal resection and adjuvant radio-chemotherapy at UMC from 11/ 2013 to 08/2016. Results: The local recurrence rate was 8,8%, the distant metastases was 19,3%. The 5 years overall survival (OS) and disease- free survival (DFS) were 82,7% and 74,6%, respectively. Conclusions: Laparoscopic resection and adjuvant radio-chemotherapy for rectal cancer was effective and safe on oncologic outcome, good results on survival. Keywords: Laparoscopic surgery, adjuvant therapy. Tóm tắt Đặt vấn đề: Phẫu thuật nội soi điều trị ung thư trực tràng có nhiều ưu điểm. Điều trị hỗ trợ sau mổ giúp cải thiện tỉ lệ tái phát tại chỗ, di căn xa và sống còn. Phương pháp nghiên cứu: Hồi cứu các người bệnh ung thư trực tràng được phẫu thuật nội soi cắt đoạn đại trực tràng và điều trị hoá - xạ trị sau mổ từ 11/2013 đến 08/2016 tại Bệnh viện Đại học Y dược TP. Hồ Chí Minh. Kết quả: Tỉ lệ tái phát tại chỗ 8.8%, di căn xa 19,3%. Tỉ lệ sống chung và sống không bệnh sau 5 năm lần lượt là 82,7% và 74,6%. Kết luận: Phẫu thuật nội soi cắt đoạn đại trực tràng và điều trị hỗ trợ trong ung thư trực tràng hiệu quả và an toàn về mặt ung thư học, kết quả tốt về mặt sống còn.

Meta Analyses

Abstract Background RCTs are considered the standard in surgical research, whereas case-matched studies and propensity score matching studies are conducted as an alternative option. Both study designs have been used to investigate the potential superiority of robotic surgery over laparoscopic surgery for rectal cancer. However, no conclusion has been reached regarding whether there are differences in findings according to study design. This study aimed to examine similarities and differences in findings relating to robotic surgery for rectal cancer by study design. Methods A comprehensive literature search was conducted using PubMed, Scopus, and Cochrane CENTRAL to identify RCTs, case-matched studies, and cohort studies that compared robotic versus laparoscopic surgery for rectal cancer. Primary outcomes were incidence of postoperative overall complications, incidence of anastomotic leakage, and postoperative mortality. Meta-analyses were performed for each study design using a random-effects model. Results Fifty-nine articles were identified and reviewed. No differences were observed in incidence of anastomotic leakage, mortality, rate of positive circumferential resection margins, conversion rate, and duration of operation by study design. With respect to the incidence of postoperative overall complications and duration of hospital stay, the superiority of robotic surgery was most evident in cohort studies (risk ratio (RR) 0.83, 95 per cent c.i. 0.74 to 0.92, P < 0.001; mean difference (MD) –1.11 (95 per cent c.i. –1.86 to –0.36) days, P = 0.004; respectively), and least evident in RCTs (RR 1.12, 0.91 to 1.38, P = 0.27; MD –0.28 (–1.44 to 0.88) days, P = 0.64; respectively). Conclusion Results of case-matched studies were often similar to those of RCTs in terms of outcomes of robotic surgery for rectal cancer. However, case-matched studies occasionally overestimated the effects of interventions compared with RCTs.
