Abstract
Locally advanced extraperitoneal rectal cancer represents a significant clinical challenge, and currently, the standard treatment is based on neoadjuvant chemoradiation therapy (CRT) followed by radical surgical resection with total mesorectal excision (TME). In the last 30 years, its management has undergone significant changes due to the improvement of complementary radio- and chemotherapy treatments, the improvement of minimally invasive surgical approaches and the diffusion of organ-sparing approaches, such as nonoperative management, commonly called "watch and wait" (NOM) and local excision (LE), in highly selected patients who achieve a major or complete response to neoadjuvant CRT. This review aimed to critically examine the efficacy and oncological safety of NOM and LE compared to those of standard TME in rectal cancer patients after neoadjuvant CRT. Both the pros and cons of these approaches were strictly analyzed, providing a comprehensive and critical overview of these novel management strategies for rectal cancer.

[PMID: 38720742 PMCID: PMC11076819 DOI: 10.1016/j.heliyon.2024.e30027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 04/17/2024] [Accepted: 04/18/2024] [Indexed: 05/12/2024] Open
Abstract
To report the first and largest systematic review and meta-analysis of radomised controlled trials (RCTs) to compare the efficacy and safety of transanal endoscopic microsurgery (TEM) and total mesorectal excision (TME) for rectal cancer for perioperative and oncological outcomes. Methods: We conducted a systematic literature retrieval via PubMed, Embase, Web of Science, and Cochrane until December 2022 for RCTs which evaluated the efficacy and/or safety between TEM and TME for rectal cancer. Outcomes included operative time, blood loss, transfusion rates, hospital stay, complication rates, recurrence rates, and mortality. Results: A total of 5 RCTs involving 545 patients (272 TEM versus 273 TME) were included for the meta-analysis. There were no significant differences between the two groups for age, gender, and distance from lower border of tumor to anal verge. Meta-analysis found that the TEM group was significantly favorable than the TME group for blood loss (WMD: 172.01; 95 % CI: 212.78, -131.24; P < 0.00001), hospital stay (WMD: 2.58; 95 % CI: 3.01, -2.16; P < 0.00001), operative time (WMD: 81.86; 95 % CI: 87.51, -76.21; P < 0.00001) and transfusion rates (RR: 0.05; 95 % CI: 0.01, 0.38; P = 0.004). The complication rates (RR: 0.60; 95 % CI: 0.32, 1.11; P = 0.10), recurrence rates (RR: 1.10; 95 % CI: 0.66, 1.83; P = 0.72), and mortality (RR: 1.23; 95 % CI: 0.67, 2.26; P = 0.51) were similar in the two groups. Conclusions: TEM was an effective and safe approach with advantages in perioperative outcomes compared with TME approach. Caution should be exercised in interpreting the differences in surgical complications between TEM and TME group due to significant heterogeneity and instability.

Abstract
A rise in the incidence of early rectal cancer consequent to bowel-screening programs around the world and an increase in the incidence in young adults has led to a growing interest in organ-sparing treatment options. The rectum, being the most distal portion of the large intestine, is a fertile ground for local excision techniques performed with endoscopic or surgical techniques. Moreover, the advancement in endoscopic optical evaluation and the better definition of imaging techniques allow for a more precise local staging of early rectal cancer. Although the local treatment of early rectal cancer seems promising, in clinical practice, a significant number of patients who could benefit from local excision techniques undergo total mesorectal excision (TME) as the first approach. All relevant prospective clinical trials were identified through a computer-assisted search of the PubMed, EMBASE, and Medline databases until January 2024. This review is dedicated to endoscopic and surgical local excision in the treatment of early rectal cancer and highlights its possible role in current and future clinical practice, taking into account surgical completion techniques and chemoradiotherapy.

Completion total mesorectal excision after neoadjuvant radiochemotherapy and local excision for rectal cancer. Colorectal Dis 2024; 26:281-289. [PMID: 38131642 DOI: 10.1111/codi.16834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 09/10/2023] [Accepted: 11/18/2023] [Indexed: 12/23/2023]
Abstract
AIM Local excision (LE) in selected cases after neoadjuvant radiochemotherapy (RCT) for locally advanced rectal cancer in clinically complete or major responders has been recently reported as an alternative to standard radical resection. Completion total mesorectal excision (cTME) is generally performed when high-risk pathological features are found in LE surgical specimens. The aim of this study was to evaluate the incidence of residual tumour and lymph node metastases after cTME in patients previously treated by RCT + LE. The secondary aims were to quantify the rate of postoperative morbidity and mortality and to evaluate the long-term oncological outcome of this group of patients. METHODS All patients treated from 2007 to 2020 by LE for locally advanced rectal cancer with a clinically complete or major response to RCT who had a subsequent cTME for high-risk pathological factors (ypT >1 and/or TRG >2 and/or positive margins) were included in this multicentre retrospective study. Pathological data, postoperative short-term morbidity (classified according to Clavien-Dindo) and mortality and oncological long-term outcome after cTME were recorded in a database. Statistical analysis was performed using Wizard for iOS version 1.9.31. RESULTS A total of 47 patients were included in the study. The rate of R0 resection was 95.7%, and a sphincter-saving procedure was performed in 37 patients (78.7%), with a protective stoma rate of 78.4%. In 28 cases (59.6%), it was possible to perform a minimally invasive approach. A residual tumour (pT and/or pN) on cTME specimens was found in 21 cases (44.7%). The rate of lymph node metastases was 12.8%. The overall short-term (within 30 days) postoperative morbidity was 34%, but grade >2 postoperative complications occurred in only nine patients (19.1%), with a reoperation rate of 6.4%. No short-term postoperative deaths occurred. At a median follow-up of 57 months (range: 21-174), the long-term stoma-free rate was 70.2%, and the actuarial 5-year overall survival (OS), disease-free survival (DFS) and local control (LC) were 86.7%, 88.9% and 95.7%, respectively. CONCLUSION When patients exhibit high-risk pathological factors after RCT + LE, cTME should be suggested due to the high risk of residual tumour or lymph node involvement (44.7%). The results after cTME in terms of the rate of R0 resection, sphincter-saving procedure, postoperative morbidity and mortality and long-term oncological outcome seem to be acceptable and do not represent a contraindication to use LE as a first-step treatment in patients with major or complete clinical response after RCT.

Abstract
OBJECTIVES This study aimed to compare the efficacy of local excision (LE) and intersphincteric resection (ISR) in patients with locally advanced rectal cancer who achieved a significant or complete pathological response following neoadjuvant chemoradiotherapy. METHODS We performed a retrospective analysis of data from patients with stage ypT0-1ycN0 low rectal cancer after neoadjuvant chemoradiotherapy who underwent LE or ISR between June 2016 and June 2021. Baseline characteristics, short-term outcomes, long-term oncological outcomes, and functional outcomes, were compared between the two groups. To reduce the selection bias, inverse probability of treatment weighting (IPTW) was performed. RESULTS This study included 106 patients (LE group: n = 51, ISR group: n = 55). There were significant differences in baseline characteristics between the two groups (P < 0.05). After IPTW, there were almost no significant differences in baseline data between the two groups. The LE group showed less postoperative complications and better function outcomes compared to the ISR group. The LE group had significantly lower rates of complications (13.7% vs. 36.4%, P = 0.014). There were no significant differences between the two groups in terms of long-term oncological outcomes. CONCLUSIONS For patients with locally advanced low rectal cancer achieving significant or complete pathological response after neoadjuvant therapy, both LE and ISR present comparable oncological outcomes. Yet, LE seems to show more advantages in terms of postoperative complications and functional outcomes. These findings offer important insights for surgical decision-making, emphasizing the necessity to consider both oncological and functional outcomes in selecting the optimal surgical approach.

Abstract
AIM The purpose of this meta-analysis is to compare the long-term efficacy of transanal local excision (TLE) versus total mesorectal excision (TME) following neoadjuvant therapy for rectal cancer. METHOD The Web of Science, Pubmed, Medline, Embase, and the Cochrane Library were systematically searched for correlational research. The Newcastle-Ottawa Scale and the Cochrane risk of bias tool were used to assess the quality of cohort studies (CSs) and randomized controlled trials (RCTs), respectively. Statistically analyzed using RevMan5.4. RESULT A total of 13 studies, including 3 randomized controlled trials (RCTs) and 10 cohort studies (CSs), involving 1402 patients, were included in the analysis. Of these, 570 patients (40.66%) underwent TLE, while 832 patients (59.34%) underwent TME. In the meta-analysis of CSs, no significant difference was observed between the TLE group and TME group regarding 5-year overall survival (OS) and 5-year disease-free survival (DFS) (P > 0.05). However, the TLE group had a higher rates of local recurrence (LR) [risk ratio (RR) = 1.93, 95%CI (1.18, 3.14), P = 0.008] and a lower rates of 5-years local recurrence-free survival (LRFS) [hazard ratio (HR) = 2.79, 95%CI (1.04, 7.50), P = 0.04] compared to the TME group. In the meta-analysis of RCTs, there was no significant difference observed between the TLE group and TME group in terms of LR, 5-year OS, 5-year DFS, and 5-year disease-specific survival (P > 0.05). CONCLUSION After undergoing neoadjuvant therapy, TLE may provide comparable 5-year OS and DFS to TME for rectal cancer. However, neoadjuvant therapy followed by TLE may has a higher LR and lower 5-year LRFS compared to neoadjuvant therapy followed by TME, so patients should be carefully selected. Neoadjuvant therapy followed by TLE may be a suitable option for patients who prioritize postoperative quality of life. However, the effectiveness of this approach requires further research to draw a definitive conclusion.

Abstract
BACKGROUND Radical resection is typically the standard treatment for early- and mid-stage rectal cancer as local resection may result in a high rate of recurrence and risk of distant metastasis. A growing number of studies have shown that local excision after neoadjuvant chemotherapy or chemoradiotherapy can significantly reduce recurrence rates and is a feasible strategy to preserve the rectum as an alternative to conventional radical resection. OBJECTIVE This study aims to compare the efficacy of local resection after neoadjuvant chemotherapy or chemoradiotherapy with radical surgery for early- and mid-stage rectal cancer and to report the evidence-based clinical advantages of both techniques. METHODS Clinical trials comparing oncologic and perioperative outcomes of local and radical resection after neoadjuvant chemotherapy or chemoradiotherapy in patients with early- to mid-stage rectal cancer were searched in PubMed, Embase, Web Of Science, and Cochrane databases, and a total of 5 randomized controlled trials and 11 cohort study trials were included. RESULTS In terms of oncology and perioperative outcomes, there were no statistically significant differences between the radical resection group and the local resection group in terms of OS [HR = 0.99, 95%CI (0.85, 1.15), p = 0.858], DFS [HR = 1.01, 95%CI (0.64, 1.58), p = 0.967], distant metastasis rate [RR = 0.76, 95%CI (0.36,1.59), p = 0.464], and local recurrence rate [RR = 1.30, 95%CI (0.69, 2.47), p = 0.420]. However, there were significant differences in the outcomes of complications [RR = 0.49, 95% CI (0.33, 0.72), p < 0.001], length of hospital stays [WMD = - 5.13, 95%CI (- 6.22, - 4.05), p < 0.001], enterostomy [RR = 0.13, 95%CI (0.05, 0.37), p < 0.001], operative time [- 94.31, 95%CI (- 117.26, - 71.35), p < 0.001], and emotional functioning score [WMD = 2.34, 95% CI (0.94, 3.74), p < 0.001]. CONCLUSION Local resection after neoadjuvant chemotherapy or chemoradiotherapy may be an effective alternative to radical surgery in patients with early and middle rectal cancer.
