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.

Abstract
BACKGROUND The coronavirus disease-19 (COVID-19) pandemic has changed the course of diseases that require emergency surgery. OBJECTIVE To evaluate the effect of the COVID-19 pandemic on colorectal cancer disease stage. DESIGN AND SETTING Retrospective analysis in the city of Rize, Turkey. METHODS This was a comparative analysis on two groups of patients with various symptoms who underwent surgical colorectal cancer treatment. Group 1 comprised patients operated between March 11, 2019, and December 31, 2019; while group 2 comprised patients at the same time of the year during the COVID-19 pandemic. RESULTS Groups 1 and 2 included 56 and 48 patients, respectively. The rate of presentation to the emergency service was higher in Group 2 (P < 0.02). The stage of the pathological lymph nodes and the rate of liver metastasis was higher in Group 2 (P < 0.004 and P < 0.041, respectively). The disease stage was found to be more advanced in Group 2 (P < 0.005). The rate of postoperative complications was higher in Group 2 (P < 0.014). CONCLUSION The presentation of patients with suspicious findings to the hospital was delayed, due both to the fear of catching COVID-19 and to the pandemic precautions that were proposed and implemented by healthcare authorities worldwide. Among the patients who presented to the hospital with emergency complaints and in whom colorectal cancer was detected, their disease was at a more advanced stage and thus a higher number of emergency oncological surgical procedures were performed on those patients.

Colorectal Dis 2021; 23:2859-2869. [PMID: 34310840 DOI: 10.1111/codi.15836] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 06/28/2021] [Accepted: 07/19/2021] [Indexed: 12/30/2022]
Abstract
AIM To investigate the conflicting consequences of faecal diversion on stoma outcomes and anastomotic leakage in anterior resection for rectal cancer, including interaction effects determined by the extent of mesorectal excision. METHOD Anterior resections between 2007 and 2016 were identified using the Swedish Colorectal Cancer Registry. National Patient Registry data were added to determine stoma outcome 2 years after surgery. Tumour distance from the anal verge constituted a proxy for extent of mesorectal excision [total mesorectal excision (TME): ≤10 cm; partial mesorectal excision (PME): 13-15 cm]. With confounder-adjusted probit regression, the total effect of defunctioning stoma on permanent stoma, and the interaction effect of extent of mesorectal excision, were estimated together with the indirect effect through anastomotic leakage. Baseline risks, risk differences (RDs) and relative risks (RRs) were reported. RESULTS The main study cohort included 4529 patients. Defunctioning stomas influenced the absolute permanent stoma risk (TME: RD 0.11 [95% CI 0.09-0.13]; PME: RD 0.15 [95% CI 0.13-0.16]). The baseline risk was higher in TME, with a resulting greater RR in PME (2.23 [95% CI 1.43-3.02] vs 4.36 [95% CI 3.05-5.68]). The indirect reduction in permanent stoma rates, due to the alleviating effect of faecal diversion on anastomotic leakage, was small (TME: 0.89 [95% CI 0.81-0.96]; PME: 0.96 [95% CI 0.91-1.00]). CONCLUSION In anterior resection for rectal cancer, defunctioning stomas may reduce chances of a stoma-free outcome. Considering leakage reduction benefits, consequences of routine diversion in TME might be fairly balanced, while this seems questionable in PME.

Abstract
BACKGROUND A more extensive resection is often required in locally advanced rectal cancer, depending on preoperative neoadjuvant treatment response. OBJECTIVE Circumferential margin involvement and postoperative outcomes after total mesorectal excision and multivisceral resection were assessed in patients with clinical locally advanced (cT4) rectal cancer at a national level. DESIGN This is a population-based study. SETTINGS Data were retrieved from the Dutch Colorectal Audit. PATIENTS A total of 2242 of 2881 patients with cT4 rectal cancer between January 2009 and December 2017 were selected. MAIN OUTCOME MEASURES Main outcomes were resection margins, postoperative complications, and mortality. RESULTS Multivisceral resection was performed in 936 of 2242 patients, of whom 629 underwent extended multivisceral resection. Positive circumferential margin rate was higher after multivisceral resection than after total mesorectal excision: 21.2% vs 13.9% (p < 0.001). More postoperative complications occurred after limited and extended multivisceral resections than after total mesorectal excision (44.1% and 53.8% vs 37.6%, p < 0.001). Incidence of 30-day mortality was similarly low in both groups (1.5% vs 2.2%, p = 0.20). Independent predictors of postoperative complications were age ≥70 years (OR, 1.28 [95% CI, 1.04-1.56]; p = 0.02), male sex (OR, 1.68 [95% CI, 1.38-2.04]; p< 0.001), mucinous tumors (OR, 1.55 [95% CI, 1.06-2.27]; p = 0.02), extended multivisceral resection (OR, 1.98 [95% CI, 1.56-2.52]; p< 0.001), Hartmann procedure (OR, 1.42 [95% CI, 1.07-1.90]; p = 0.02), and abdominoperineal resection (OR, 1.56 [95% CI, 1.25-1.96]; p < 0.001). LIMITATIONS Data specifying the extent of multivisceral resections and Clavien Dindo I to II complications were not available. CONCLUSIONS This population-based study revealed relatively high circumferential margin positivity and postoperative complication rates in patients with cT4 rectal cancer, especially after multivisceral resections, but low mortality rates.

Abstract
INTRODUCTION Outcomes of rectal cancer treatment depend on preoperative staging and the effectiveness of treatments. According to disease staging, different variants of combined therapy (surgery, chemo- and radiotherapy) are used. Available parameters such as overall survival rates and disease- free survival rates as well as the presence of recurrence are inaccurate and should be jointly considered. MATERIAL AND METHODS Data from 138 patients with rectal cancer (I-III WHO), who were radically operated on in the period 2001-2004 in Bydgoszcz Oncology Centre were analysed. Among this group 84 patients were radically operated on one week after preoperative radiotherapy 5 × 5 Gy (sRT). We established a new parameter, the overall treatment outcome (OTO), based on the finding that there was no recurrence (local recurrence, distant metastases) of the disease within 5 years, which is generally considered a good result for the treatment of rectal cancer. RESULTS Among all patients (n = 138) and patients following sRT (n = 84) 7.4%...5.9% local recurrence and 24%...29% distant metastases were observed in 5-year follow-up. Recurrence was found in 30% and 31% of patients, respectively. Analysis of results on the basis of the OTO parameter demonstrated that among all groups of patients a worse treatment outcome is related to the number of lymph nodes involved, pN, pT, cancer stage (WHO) and to pN and patient age in the sRT group (p < 0.005). CONCLUSIONS In using a combined therapy, it is possible to optimise rectal cancer treatment outcomes. The OTO parameter is a useful tool for defining these results of cancer combination treatment.

Abstract
Purpose/aim: Preoperative chemoradiotherapy (pre-CRT) and total mesorectal excision (TME) have become the standard of care for patients with locally advanced rectal cancer (LARC). Nevertheless, it is a controversial issue whether pre-CRT in cT3N0M0 patients would result in potential overtreatment. Materials and methods: In total, 183 clinical stage IIA rectal cancer patients treated with and without pre-CRT between 2011 and 2014 were retrospectively analyzed. Capecitabine/FOLFOX/CAPOX chemotherapy was co-administered with preoperative radiotherapy. Surgical resection with laparoscopic or open TME was conducted 8-12 weeks after completion of the pre-CRT. Postoperative radiotherapy was routinely given to patients with pT4 lesion or circumferential margin (CRM) and/or distal resection margin (DRM) involvement. Results: In total, 108 (59%) patients received pre-CRT and 75 (41%) underwent surgery first. The pre-CRT patients presented with less-advanced pathological T stage tumors compared with the surgery-first patients (p < 0.001). However, the pathological N stage was not significantly different between the two groups (p = 0.065). The 3-year overall survival (OS), disease-free survival (DFS), and 2-year local recurrence (LR) rate were similar in the pre-CRT and surgery-first patients (88.4 versus 88.7%, p = 0.552; 79.6 versus 83.3%, p = 0.797; 2.8 versus 2.7%, p = 0.960, respectively). Cox regression analysis showed that pN stage and CRM/DRM involvement were independently correlated with an unfavorable DFS. Conclusions: In this study, the omission of pre-CRT in cT3N0M0 patients did not translate into a worse oncological outcome. Postoperative radiotherapy should remain a standard option for patients with CRM/DRM involvement and pathological T4 tumors. A generalized indication for pre-CRT in cT3N0 patients is likely to result in overtreatment.

Abstract
Introduction In the surgical treatment of rectal cancer, a clear circumferential resection margin and distal resection margin should be obtained. The aim of this study was to determine the morbidity, mortality, survival outcome, and local failure after total mesorectal excision (TME) in the surgical treatment of rectal cancer. Methods This retrospective study was conducted on 101 patients treated for rectal cancer using low anterior resection (LAR), abdominoperinial resection (APR), or Hartmaan’s technique. In all operative procedures, total mesorectal excisions (TMEs) were done. The patients were treated from November 2000 to April 2011 in the South Egypt Cancer Institute (SECI) of Assuit University (Egypt). Neo-adjuvant therapy was given to those patients with serosalin filtration, lymph node involvement, and sexual and urinary function impairment. Data were analyzed using IBM-SPSS version 21, and survival rates were estimated using the Kaplan-Meier method. Results One hundred one patients were evaluable (61 males, 40 females). Regarding the operative procedure used, it was: (APR), LAR, Hartmaan’s technique in 15.8%, 71.3%, and 12.9% of patients, respectively. Operation-related mortality during the 30 days after surgery was 3%. The operations resulted in morbidity in 25% of the patients, anastomotic site leak in 5.9% of the patients, urinary dysfynction in 9.9% of the patients, and erectile dysfunction in 15.8% of the male patients. Regarding safety margin, the median distances were distal/radial margin, 23/12 mm, distal limit 7 cm. Median lymph nodes harvest 19 nodes. Primary tumor locations were anteriorly 23.8%, laterally 13.9%, posteriorly 38.6%, and circumferential 23.8%. Protective stoma 16.8%. Primary Tumor TNM classification (T1, T2, T3, and T4; 3, 28.7, 55.4, and 12.9%, respectively). Nodes Metastases (N0, N1, and N2; 57.4, 31.7, and 10.9%, respectively). TNM staging (I, II, III, and IV; 15.8, 29.7, 46.5, and 7.9%, respectively). Chemotherapy was administered to 67.3% of the patients. Radiotherapy (short course neoadjuvant, long course neoadjuvant, and adjuvant postoperative used in 33.7, 20.8, and 19.8% of patients, respectively). Survival 5-years CSS was 73% and 5-years RFS 71%. Mean operative time was 213 minutes. The average amount of intraoperative blood loss was 344 mL. Conclusion Total mesorectal excision (TME) represents the gold-standard technique in rectal cancer surgery. It is safe with neoadjuvent chemoradiotherapy and provides both maximal oncological efficiency (local control and long-term survival and maintenance of a good quality of life).

Abstract
Colorectal cancer is the second most common cancer in women and the third most common in men worldwide. In this study, we used MEDLINE to conduct a systematic review of existing literature published in English between 2000 and 2010 on patterns of colorectal cancer care. Specifically, this review examined 66 studies conducted in Europe, Australia, and New Zealand to assess patterns of initial care, post-diagnostic surveillance, and end-of-life care for colorectal cancer. The majority of studies in this review reported rates of initial care, and limited research examined either post-diagnostic surveillance or end-of-life care for colorectal cancer. Older colorectal cancer patients and individuals with comorbidities generally received less surgery, chemotherapy, or radiotherapy. Patients with lower socioeconomic status were less likely to receive treatment, and variations in patterns of care were observed by patient demographic and clinical characteristics, geographical location, and hospital setting. However, there was wide variability in data collection and measures, health-care systems, patient populations, and population representativeness, making direct comparisons challenging. Future research and policy efforts should emphasize increased comparability of data systems, promote data standardization, and encourage collaboration between and within European cancer registries and administrative databases.

Abstract
BACKGROUND Mesorectal grading was reported to be a valuable prognostic factor in rectal cancer surgery. Previous studies were retrospective, and had short follow-up. OBJECTIVE To assess the long-term influence of total mesorectal excision quality on disease recurrence in mid and low rectal cancer patients who received preoperative neoadjuvant chemoradiotherapy (CRT) and postoperative chemotherapy. METHODS One hundred twenty-one patients with rectal cancer had either low anterior resection or abdominoperineal resection. All patients received neoadjuvant CRT and postoperative chemotherapy. Main outcome measures included TNM staging, involvement of the circumferential resection margin (ICRM), mesorectal grading, local and systemic recurrences were recorded. RESULTS Follow-up was done for at least 5 years or up to disease recurrence whatever comes first. Mean follow-up time was 59.4 months. Twenty-nine patients had abdominoperineal resection and 92 had low anterior resection. About 7.5% had positive CRM which was significantly correlated with mesorectal grading. Grade 3 mesorectal specimens were obtained in approximately 60% of patients, 27% had grade 2, and only 13% had grade 1 (poor) mesorectal specimens. Poorer mesorectal grading increased with APR and lower rectal tumors. Recurrences occurred in 20% of patients (40% in the first 2 years, 32% in the 3rd year, and 28% in the 4th and 5th years); factors affecting recurrence included lymphovascular invasion, ICRM, and N stage. Mesorectal grading was not a valuable prognostic factor for recurrence unless it resulted in ICRM. Recurrences occurred earlier with poorer mesorectal grade, yet this was not statistically significant. CONCLUSIONS Mesorectal grading is a pathologic description that reflects the quality of surgery. However, in patients who received neoadjuvant CRT and postoperative chemotherapy, grading had no long-term prognostic value regarding recurrences unless it resulted in ICRM.

Systematic review of anastomotic leakage rate according to an international grading system following anterior resection for rectal cancer. PLoS One 2013; 8:e75519. [PMID: 24086552 PMCID: PMC3783382 DOI: 10.1371/journal.pone.0075519] [Citation(s) in RCA: 52] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2013] [Accepted: 08/13/2013] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND A generally acceptable definition and a severity grading system for anastomotic leakages (ALs) following rectal resection were not available until 2010, when the International Study Group of Rectal Cancer (ISGRC) proposed a definition and a grading system for AL. METHODS A search for published data was performed using the MEDLINE database (2000 to December 5, 2012) to perform a systematic review of the studies that described AL, grade AL according to the grading system, pool data, and determine the average rate of AL for each grade after anterior resection (AR) for rectal cancer. RESULTS A total of 930 abstracts were retrieved; 40 articles on AR, 25 articles on low AR (LAR), and 5 articles on ultralow AR (ULAR) were included in the review and analysis. The pooled overall AL rate of AR was 8.58% (2,085/24,288); the rate of the asymptomatic leakage (Grade A) was 2.57%, that of AL that required active intervention without relaparotomy (Grade B) was 2.37%, and that of AL that required relaparotomy (Grade C) was 5.40%. The pooled rate of AL that required relaparotomy was higher in AR (5.40%) than in LAR (4.70%) and in ULAR (1.81%), which could be attributed to the higher rate of protective defunctioning stoma in LAR (40.72%) and ULAR (63.44%) compared with that in AR (30.11%). CONCLUSIONS The new grading system is simple that the ALs of each grade can be easily extracted from past publications, therefore likely to be accepted and applied in future studies.

Abstract
The aim of this study was to evaluate the feasibility and the effectiveness of preoperative radiochemotherapy followed by total mesorectal excision (TME) and sphincter-preserving procedures for T3 low rectal cancer. Patients with rectal cancer and T3 tumors located within 1-6 cm of the dentate line received preoperative radiochemotherapy. Concurrent 5-fluorouracil-based radiochemotherapy was used. Radical resection with TME and sphincter-preserving procedures were performed during the six to eight weeks following radiotherapy. Survival was analyzed using the Kaplan-Meier method. The anal function was evaluated using the Wexner score. The clinical response rate was 83.5%, overall downstaging of T classification was 75.3% and pathological complete response was 15.3%. The anastomotic fistula rate was 4.7%. A median follow-up of 30 months showed the local recurrence rate to be 4.7% and the distant metastasis rate to be 5.9%. The three-year overall survival rate was 87%. The degree of anal incontinence as measured using the Wexner score decreased over time, and the anal sphincter function in the majority of patients gradually improved. Preoperative radiochemotherapy was found to improve tumor downstaging, reduces local recurrence, increase the sphincter preservation rate, and is therefore of benefit to patients with T3 low rectal cancer.

Complications as indicators of quality assurance after 401 consecutive colorectal cancer resections: the importance of surgeon volume in developing colorectal cancer units in India. World J Surg Oncol 2012; 10:15. [PMID: 22257531 PMCID: PMC3269979 DOI: 10.1186/1477-7819-10-15] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2011] [Accepted: 01/18/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The low incidence of colorectal cancer in India, coupled with absence of specialized units, contribute to lack of relevant data arising from the subcontinent. We evaluated the data of the senior author to better define the requirements that would enable development of specialized units in a country where colorectal cancer burden is increasing. METHODS We retrospectively analyzed data of 401 consecutive colorectal resections from a prospective database of the senior author. In addition to patient demographics and types of resections, perioperative data like intraoperative blood loss, duration of surgery, complications, re-operation rates and hospital stay were recorded and analyzed. RESULTS The median age was 52 years (10-86 years). 279 were males and 122 were females. The average duration of surgery was 220.32 minutes (range 50-480 min). The overall complication rate was 12.2% (49/401) with a 1.2% (5/401) mortality rate. The patients having complications had an increase in their median hospital stay (from 10.5 days to 23.4 days) and the re-operation rate in them was 51%. The major complications were anastomotic leaks (2.5%) and stoma related complications (2.7%). CONCLUSIONS This largest ever series from India compares favorably with global standards. In a nation where colorectal cancer is on the rise, it is imperative that high volume centers develop specialized units to train future specialist colorectal surgeons. This would ensure improved quality assurance and delivery of health care even to outreach, low volume centers.

The role of lateral lymph node dissection in the management of lower rectal cancer. Langenbecks Arch Surg 2011; 397:353-61.

Abstract
INTRODUCTION Lateral lymph node involvement is a problem encountered in patients with low rectal cancers. This has been documented in both anatomical and pathological studies. Currently, the vast majority of centers have concentrated on the use of chemoradiation to obtain better local control and manage these nodes indirectly. In Japan, extended nodal dissection for the control of pelvic nodal disease has seen further advancement. This paper discusses the key issues involved in the management of pelvic lateral nodes in low rectal cancers. METHODS A review of available literature and critical appraisal of the entity of lateral nodes in low rectal cancers, the treatment options, and oncological and functional results were performed. RESULTS There are good data showing that the entity of pelvic lateral nodes in low rectal cancers should not be ignored. Recent data have emerged showing that radiotherapy is associated with significant long-term functional side effects. Refinement of the technique, lateral node dissection, has led to good local control as well as good functional outcomes. CONCLUSION In this context, there needs to be a reevaluation of the role of chemoradiation as the sole treatment for lateral nodal disease in centers outside of Japan. Individualization of the treatment of rectal cancer may require all centers to be able to offer both modalities.

Extended abdominoperineal excision vs. standard abdominoperineal excision in rectal cancer--a systematic overview. Int J Colorectal Dis 2011; 26:1227-40. [PMID: 21603901 DOI: 10.1007/s00384-011-1235-3] [Citation(s) in RCA: 99] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 05/03/2011] [Indexed: 02/04/2023]
Abstract
BACKGROUND After introduction of total mesorectal excision (TME) as the gold standard for rectal cancer surgery, oncologic results appeared to be inferior for abdominoperineal excision (APE) as compared to anterior resection. This has been attributed to the technique of standard APE creating a waist at the level of the tumor-bearing segment. This systematic review investigates outcome of both standard and extended techniques of APE regarding inadvertent bowel perforation, circumferential margin (CRM) involvement, and local recurrence. METHODS A literature search was performed to identify all articles reporting on APE after the introduction of TME using Medline, Ovid, and Embase. Extended APE was defined as operations that resected the levator ani muscle close to its origin. All other techniques were taken to be standard. Studies so identified were evaluated using a validated instrument for assessing nonrandomized studies. Rates for perforation, CRM involvement, and local recurrence were compared using chi-square statistics. RESULTS In the extended group, 1,097 patients, and in the standard group, 4,147 patients could be pooled for statistical analysis. The rate of inadvertent bowel perforation and the rate of CRM involvement for extended vs. standard APE was 4.1% vs. 10.4% (relative risk reduction 60.6%, p = 0.004) and 9.6% vs. 15.4% (relative risk reduction 37.7%, p = 0.022), respectively. The local recurrence rate was 6.6% vs. 11.9% (relative risk reduction 44.5%, p < 0.001) for the two groups. CONCLUSION This systematic review suggests that extended techniques of APE result in superior oncologic outcome as compared to standard techniques.
