World J Surg Oncol 2021; 19:116. [PMID: 33849564 PMCID: PMC8045195 DOI: 10.1186/s12957-021-02223-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Accepted: 04/01/2021] [Indexed: 01/04/2023] Open
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.

Comparative short- and long-term outcomes of three techniques of natural orifice specimen extraction surgery for rectal cancer. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2020; 46:e55-e61. [PMID: 32782201 DOI: 10.1016/j.ejso.2020.06.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Revised: 06/08/2020] [Accepted: 06/12/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND The aim of this study was to evaluate the safety of natural orifice specimen extraction surgery (NOSES) and to compare the short- and long-term outcomes of three techniques of NOSES for rectal cancer (RC). MATERIALS AND METHODS A consecutive series of RC patients in stage I-III who underwent laparoscopic NOSES were enrolled. Three main techniques of NOSES included specimen eversion and extra-abdominal resection (EVER), specimen extraction and extra-abdominal resection (EXER) and intra-abdominal resection and specimen extraction (IREX). The postoperative complications, 5-year disease free survival (DFS), 5-year local recurrence rate (LRR) and 5-year distant metastasis rate (DMR) were compared in three techniques. RESULTS 268 RC patients met inclusion criteria, including 83 patients treated with EVER, 75 patients treated with EXER and 110 patients treated with IREX. Tumor location was the most critical factor associated with technique selection, with P < 0.001. Postoperative complication rate was 12.3% for all patients, and it was 18.1% for EVER, 13.3% for EXER and 7.3% for IREX. There were no significant differences for anastomotic leakage, anastomotic bleeding and intraabdominal abscess among three technique groups, with P > 0.05. For long-term outcomes, the 5-year DFS, 5-year LRR and 5-year DMR were 85.03%, 4.22% and 11.00% for all patients. Patients in advanced tumor stage have worse long-term survival compared with patients in early stage, but no significant survival differences were observed among three technique groups. CONCLUSION Three techniques of NOSES for RC had acceptable short- and long-term outcomes, and tumor location was a determinant of technique selection.
