Li X, Fu R, Ni H, Du N, Wei M, Zhang M, Shi Y, He Y, Du L. Effect of Neoadjuvant Therapy on the Functional Outcome of Patients With Rectal Cancer: A Systematic Review and Meta-Analysis. Clin Oncol (R Coll Radiol) 2023; 35:e121-e134. [PMID: 35940977 DOI: 10.1016/j.clon.2022.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 06/12/2022] [Accepted: 07/04/2022] [Indexed: 01/18/2023]
Abstract
AIMS The impact of neoadjuvant therapy on the functional outcome of patients with resectable rectal cancer is still controversial. The aim of the present study was to explore the effects of neoadjuvant therapy on anorectal function (ARF), urinary function and sexual function in relevant patients. MATERIALS AND METHODS PubMed, Embase, Web of Science and the Cochrane Library were searched systematically. All English-language studies, published from January 2000 to July 2021, that explored the (postoperative) effects of neoadjuvant therapy versus upfront surgery on ARF, urinary function and sexual function of patients were included (PROSPERO 2021: CRD42021281617). RESULTS The data in this study were derived from 37 articles based on 33 studies; in total, 17 917 patients were enrolled. The meta-analysis revealed that the incidence of anorectal dysfunction in the neoadjuvant therapy group was significantly higher than that in the group of upfront surgery, which was manifested by a higher incidence of major low anterior resection syndrome (odds ratio = 3.09, 95% confidence interval = 2.48, 3.84; P < 0.001), reduction of mean squeeze pressure and mean resting pressure, and other manifestations, including clustering of stools, incontinence, urgency and use of pads. With the extension of follow-up time, the adverse effects of neoadjuvant therapy on major low anterior resection syndrome existed. Compared with patients undergoing upfront surgery, neoadjuvant therapy increased the risk of urinary incontinence (odds ratio = 1.31, 95% confidence interval = 1.00, 1.72; P = 0.05) and erectile dysfunction (odds ratio = 1.77, 95% confidence interval = 1.27, 2.45; P < 0.001). CONCLUSION Compared with upfront surgery, neoadjuvant therapy is not only associated with impairment of ARF, but also with increased incidence of urinary incontinence and male erectile dysfunction. However, the influence of confounding factors (e.g. surgical method, tumour stage) needs to be considered.

Short- and long-term outcomes in ypT2 rectal cancer patients after neoadjuvant therapy and local excision: a multicentre observational study. Tech Coloproctol 2023; 27:53-61. [PMID: 36239872 PMCID: PMC9807481 DOI: 10.1007/s10151-022-02712-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Accepted: 10/04/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND Although local excision (LE) after neoadjuvant treatment (NT) has achieved encouraging oncological outcomes in selected patients, radical surgery still remains the rule when unfavorable pathology occurs. However, there is a risk of undertreating patients not eligible for radical surgery. The aim of this study was to evaluate the outcomes of patients with pathological incomplete response (ypT2) in a multicentre cohort of patients undergoing LE after NT and to compare them with ypT0-is-1 rectal cancers. METHODS From 2010 to 2019, all patients who underwent LE after NT for rectal cancer were identified from five institutional retrospective databases. After excluding 12 patients with ypT3 tumors, patients with ypT2 tumors were compared to patients with ypT0-is-1 tumors). The endpoints of the study were early postoperative and long-term oncological outcomes. RESULTS A total of 177 patients (132 males, 45 females, median age 70 [IQR 16] years) underwent LE following NT. There were 46 ypT2 patients (39 males, 7 females, median age 72 [IQR 18.25] years) and 119 ypT0-is-1 patients (83 males, 36 females, median age 69 [IQR 15] years). Patients with pathological incomplete response (ypT2) were frailer than the ypT0-is-1 patients (mean Charlson Comorbidity Index 6.15 ± 2.43 vs. 5.29 ± 1.99; p = 0.02) and there was a significant difference in the type of NT used for the two groups (long- course radiotherapy: 100 (84%) vs. 23 (63%), p = 0.006; short-course radiotherapy: 19 (16%) vs. 17 (37%), p = 0.006). The postoperative rectal bleeding rate (13% vs. 1.7%; p = 0.008), readmission rate (10.9% vs. 0.8%; p = 0.008) and R1 resection rate (8.7% vs. 0; p = 0.008) was significantly higher in the ypT2 group. Recurrence rates were comparable between groups (5% vs. 13%; p = 0.15). Five-year overall survival was 91.3% and 94.9% in the ypT2 and ypT0-is-1 groups, respectively (p = 0.39), while 5-year cancer specific survival was 93.4% in the ypT2 group and 94.9% in the ypT0-is-1 group (p = 0.70). No difference was found in terms of 5-year local recurrence free-survival (p = 0.18) and 5-year distant recurrence free-survival (p = 0.37). CONCLUSIONS Patients with ypT2 tumors after NT and LE have a higher risk of late-onset rectal bleeding and positive resection margins than patients with complete or near complete response. However, long-term recurrence rates and survival seem comparable.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy followed by radical surgery is the standard curative treatment for mid- to low-rectal cancer. However, the combination of these treatments may affect patients' GI and genitourinary functions and their quality of life. In the cases of good clinical response to neoadjuvant treatment, local excision is a rectal sparing strategy that would limit these side effects. OBJECTIVE The aim of this study is to compare the effects of local excision or conventional laparoscopic total mesorectal excision after chemoradiotherapy in patients with rectal cancer. DESIGN The design is a retrospective study. SETTING The setting used is a single tertiary center. PATIENTS Patients with mid- to low-rectal cancer treated with chemoradiotherapy and accessible via conservative surgery at our hospital between January 2010 and December 2018 were included. Patients undergoing local excision were matched 1 to 1 with the patients undergoing total mesorectal excision by age, sex, body mass index, tumor height, and year of surgery. MAIN OUTCOME MEASURES Quality of life and digestive and genitourinary functions were measured using validated questionnaires. The socioeconomic impact was also assessed. RESULTS Forty-four patients undergoing local excision agreed to participate and were matched with 44 patients undergoing total mesorectal excision. Patients who underwent local excision reported a more favorable global health status ( p < 0.01), emotional function ( p = 0.035), social function ( p = 0.04), and body image ( p = 0.04). The low anterior resection syndrome score (rate of major syndrome, 23.8% vs 54.5%; p < 0.01) and the specific fecal incontinence subscale score ( p < 0.01) were more favorable in the local excision group. Sexual and urinary outcomes were comparable between the 2 groups. Local excision had a lower impact on the professional status (35.7% vs 76.5%; p = 0.03). LIMITATIONS The study limitations include its retrospective design and small sample size. CONCLUSIONS When indicated, local excision improves the bowel function and quality of life of patients undergoing surgery for rectal cancer after chemoradiotherapy compared with total mesorectal excision.

Abstract
BACKGROUND The treatment of distal rectal cancer may be accompanied by evacuation disorders of multifactorial etiology. Neoadjuvant chemoradiotherapy (NCRT) is part of the standard treatment for patients with locally advanced extraperitoneal rectal cancer. The assessment of anorectal function after long-term NCRT in patients with cancer of the extraperitoneal rectum has been poorly evaluated. OBJECTIVE The aim of the present study was to evaluate the effects of NCRT on anorectal function and continence in patients with extraperitoneal rectal cancer. METHODS Rectal adenocarcinoma patients undergoing neoadjuvant therapy were submitted to functional evaluation by anorectal manometry and the degree of fecal incontinence using the Jorge-Wexner score, before and eight weeks after NCRT. The manometric parameters evaluated were mean resting anal pressure (ARp), maximum voluntary contraction anal pressure (MaxSp) and average voluntary contraction anal pressure (ASp). All patients underwent the same NCRT protocol based on the application of fluoropyrimidine (5-FU) at a dosage of 350 mg/m2 associated with folic acid at a dosage of 20 mg/m2, intravenously, in the first and last week of treatment, concomitantly with conformational radiotherapy with a total dose of 50.4Gy, divided into 28 daily fractions of 1.8Gy. For statistical analysis of the quantitative variables with normal distribution, the mean, standard deviation, median and interquartile range were calculated. For comparison of two related samples (before and eight weeks after NCRT), Wilcoxon's non-parametric test was used. RESULTS Forty-eight patients with rectal cancer were included in the study, with a mean age of 62.8 (39-81) years, 36 (75%) of whom were male. The use of NCRT was associated with a decrease in the values of ARp (55.0 mmHg vs 39.1 mmHg, P<0.05) and ASp (161.9 mmHg vs 141.9 mmHg, P<0.05) without changing MaxSp values (185,5 mmHg vs 173 mmHg, P=0.05). There was no worsening of the incontinence score eight weeks after the use of NCRT (3.0 vs 3.3; P>0.05). CONCLUSION NCRT was associated with a reduction in the values of ARp and the ASp. There was no change in MaxSp, as well as in the degree of fecal continence by the Jorge-Wexner score.

Role of Local Excision for Suspected Regrowth in a Watch and Wait Strategy for Rectal Cancer. Cancers (Basel) 2022; 14:cancers14133071. [PMID: 35804843 PMCID: PMC9265129 DOI: 10.3390/cancers14133071] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 06/21/2022] [Indexed: 02/01/2023] Open
Abstract
Rectal cancer patients with a clinical complete response to neoadjuvant (chemo)radiation are eligible for Watch and Wait (W&W). For local regrowth, total mesorectal excision (TME) is considered the standard of care. This study evaluated local excision (LE) for suspected local regrowth. From 591 patients prospectively entered into a national W&W registry, 77 patients with LE for regrowth were included. Outcomes analyzed included histopathologic findings, locoregional recurrence, long-term organ preservation, and colostomy-free and overall survival. In total, 27/77 patients underwent early LE (<6 months after neoadjuvant radiotherapy) and 50/77 underwent late LE (≥6 months). Median follow-up was 53 (39−69) months. In 28/77 patients the LE specimen was histopathologically classified as ypT0 (including 9 adenomas); 11/77 were ypT1, and 38/77 were ypT2−3. After LE, 13/77 patients with ypT2−3 and/or irradical resection underwent completion TME. Subsequently, 14/64 patients without completion TME developed locoregional recurrence, and were successfully treated with salvage TME. Another 8/77 patients developed distant metastases. At 5 years, overall organ preservation was 63%, colostomy-free survival was 68%, and overall survival was 96%. There were no differences in outcomes between early or late LE. In W&W for rectal cancer, LE can be considered as an alternative to TME for suspected regrowth in selected patients who wish to preserve their rectum or avoid colostomy in distal rectal cancer.

Abstract
Abstract
Introduction Over the last decades, treatment for rectal cancer has substantially improved with development of new surgical options and treatment modalities. With the improvement of survival, functional outcome and quality of life are getting more attention.
Study objective To provide an overview of current modalities in rectal cancer treatment, with particular emphasis on functional outcomes and quality of life.
Results Functional outcomes after rectal cancer treatment are influenced by patient and tumor characteristics, surgical technique, the use of preoperative radiotherapy and the method and level of anastomosis. Sphincter preserving surgery for low rectal cancer often results in poor functional outcomes that impair quality of life, referred to as low anterior resection syndrome. Abdominoperineal resection imposes the need for a permanent stoma but avoids the risk of this syndrome. Contrary to general belief, long-term quality of life in patients with a permanent stoma is similar to those after sphincter preserving surgery for low rectal cancer.
Conclusion All patients should be informed about the risks of treatment modalities. Decision on rectal cancer treatment should be individualized since not all patients may benefit from a sphincter preserving surgery “at any price”. Non-resection treatment should be the future focus to avoid the need of a permanent stoma and bowel dysfunction.

Abstract
AIM The aim of this work was to determine the knowledge gap in the field of erectile function (EF) after colorectal cancer surgery and investigate and compare long-term male EF in colon and rectal cancer survivors in a national population. METHOD Danish male patients alive without evidence of recurrence who were treated for colon or rectal cancer between May 2001 and December 2014 were invited to participate. Using the International Index of Erectile Function (IIEF) score the derived dichotomized erectile dysfunction (ED) was defined as moderate/severe or no/mild. Patients were grouped based on type of surgery [colon resection, rectal resection (RR) or local resection] and stratified for stoma, preoperative radiotherapy (RT), age and American Society of Anesthesiologists (ASA) score. RESULTS Of 10 037 eligible patients, 4334 responded (43.18%). The EF score was significantly lower for RR (mean 12.14) compared with both colon resection (mean 15.82) and local resection (mean 14.81) (p < 0.0001). No significant difference between colon resection and local resection was found (p = 0.29). Both a stoma and the use of RT were independent risk factors for ED. After excluding patients with stoma and RT and adjusting for age and ASA score, RR still had a higher risk of ED (OR 1.42, CI 1.20-1.67) compared with colon resection. CONCLUSION RR has a negative affect on EF. No difference between patients who underwent colon resection and local resection was found. RT and stoma were independent risk factors for ED.

Abstract
The aim was to examine the current trend in rectal cancer, which is to extend ’watch-and-wait’ to earlier-stage tumors, not normally treated with chemoradiotherapy, to define the up-side and down-side regarding quality of life (QOL) and anorectal/sexual/urinary function from this approach. We reviewed the literature regarding a ‘watch-and-wait’ strategy after neoadjuvant chemoradiotherapy. The primary outcome measure was complete clinical response. Secondary measures included colostomy rate, functional outcomes and QOL. There is a trend to use chemoradiotherapy in earlier tumors using dose-escalation of radiation and/or additional chemotherapy, resulting in high rates of complete clinical response, which may impact adversely on QOL if radical surgery is subsequently required. Focusing on organ-preservation as the primary goal of treatment rather than overall functional outcomes and QOL for the whole population, may not provide patients with sufficient information for optimal decision-making.

Abstract
Purpose of Review With advances in radiation therapy (RT) techniques for rectal and anal cancers allowing for the modulation of critical normal tissues, there has been an increased emphasis on improving the quality of life (QOL) of cancer survivors. Herein, we review the literature to examine the impact of RT on QOL and patient reported outcomes (PROs) to better inform providers about the challenges of survivorship. Recent Findings Large systematic reviews, recent studies and long-term follow-up of pivotal clinical trials have shown that RT impacts QOL, particularly fecal continence and sexual function. Modern preoperative RT techniques allow for decreased dose to organs-at-risk will likely improve QOL. Summary RT, though critical in the treatment of rectal and anal cancer, has a profound impact on QOL for some patients. Recent studies have included PROs and validated QOL metrics to better inform providers and patients.

Abstract
Local excision following chemoradiotherapy in rectal cancer is an organ-preserving procedure which aims at reducing morbidity and functional disorders associated with total mesorectal excision (TME) in selected patients. Although TME after chemoradiotherapy remains the gold standard for locally advanced mid and low rectal cancer, in the last years multicenter research trials have offered encouraging oncologic results which have allowed to preserve the rectum in patients with a pathologic complete response after chemoradiotherapy. A review of the available literature on this topic was conducted to define the state of the art of this conservative approach and to focus on the most controversial aspects concerning local excision performed after chemoradiotherapy, in particular tumor scatter and lymph node status, completion and salvage surgery, morbidity and quality of life. The analysis of these topics should be considered, in trial setting or in current practice, for their clinical implications. Oncologic outcomes of recent trials are encouraging for part of the patients presenting T2 rectal cancer; however, TME still remains the standard treatment in clinical practice. In such cases, local excision should include a surgical safety margin of at least 1 cm from the resection margin to achieve a true negative margin from residual tumor cells. The selection of the patients should be carefully performed and their consensus extremely detailed because TME is necessary in about 30% of cases. Failing that, morbidity and quality of life are negatively affected. However, about half of these patients refuse radical surgery (45%), thus undergoing only palliative care.

Abstract
The management of rectal cancer has evolved substantially over recent decades, becoming increasingly complex. This was once a disease associated with high mortality and limited treatment options that typically necessitated a permanent colostomy, has now become a model for multidisciplinary evaluation, treatment and surgical advancement. Despite advances in the rates of total mesorectal excision, decreased local recurrence and increased 5-year survival rates, the multimodal treatment of rectal cancer is associated with a significant impact on long-term functional and quality of life outcomes including risks of bowel, bladder and sexual dysfunction, and potential need for a permanent stoma. There is great interest in strategies to decrease the toxicity of treatment, including selective use of radiation, chemotherapy or even surgery. The modern concept of selective use of surgery for patients with rectal cancer are based on the observed pathological complete response in approximately 10-20% of patients following long-course chemoradiation therapy. While definitive surgical resection remains the standard of care for all patients with non-metastatic rectal cancer, a growing number of studies are providing supportive evidence for a watch-and-wait, organ preserving approach in highly selected patients with rectal cancer. However, questions regarding the heterogeneity of patient selection, optimal method for inducing pathological complete response, methods and intervals for assessing treatment response and adequacy of follow-up remain unanswered. The aim of this review is to provide an up-to-date summary of the current evidence for the watch-and-wait management of rectal cancer following a complete clinical response after neoadjuvant chemoradiation.

A systematic review and meta-analysis of pT2 rectal cancer spread and recurrence pattern: Implications for target design in radiation therapy for organ preservation. Radiother Oncol 2019; 133:20-27. [PMID: 30935577 DOI: 10.1016/j.radonc.2018.12.024] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2018] [Revised: 12/20/2018] [Accepted: 12/21/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND There are no guidelines on clinical target volume (CTV) delineation for cT2 rectal cancer treated with organ preservation. MATERIALS AND METHODS A systematic review and meta-analysis were performed to determine the extent of distal mesorectal (DMS) and distal intramural spread (DIS), the risk of lateral lymph node (LLN) metastases in pT2 tumours, and regional recurrence pattern after organ preservation. RESULTS The rate of DMS > 1 cm was 1.9% (95% CI: 0.4-5.4%), maximum extent: 1.3 cm. The rate of DIS > 0.5 cm was 4.7% (95% CI: 1.3-11.5%), maximum extent: 0.8 cm. The rate of LLN metastases was 8.2% (95% CI: 6.7-9.9%) for tumours below or at peritoneal reflexion and 0% for higher tumours. Regional nodal recurrences alone were recorded in 1.0% (95% CI: 0.5-1.7%) of patients after watch-and-wait and in 2.1% (95% CI: 1.2-3.4%) after preoperative radiotherapy and local excision. Thus, the following rules for CTV delineation are proposed: caudal border 1.5 cm from the tumour to account for DMS or 1 cm to account for DIS, whichever is more caudal; cranial border at S2/S3 interspace; inclusion of LLN for tumours at or below peritoneal reflexion. A planning study was performed in eight patients to compare dose-volume parameters obtained using these rules to that obtained using current guidelines for advanced cancers. The proposed rules led to a mean 18% relative reduction of planning target volume, which resulted in better sparing of organs-at-risk. CONCLUSION This meta-analysis suggests a smaller CTV for cT2 tumours than the current guidelines designed for advanced cancers.

Abstract
Current practice of neoadjuvant therapy and total mesorectal excision (TME) in rectal cancer bears the weakness in systemic disease control and long-term functional outcomes. With increasing concerns of the balance between cure and quality of life, new strategies are developed to better oncological outcomes at least cost of function damage. Attractive options to adjust neoadjuvant modality include escalation of radiotherapy, intensification of chemotherapy, and chemoradiotherapy with consolidation or full-course chemotherapy. Subsequently, organ-preserving strategies have gained the popularity. Surgical or nonsurgical approaches that spare the rectum are used as possible alternatives for radical surgery, though high-quality TME remains the last resort to offer reliable local disease control. This review discusses new strategies of neoadjuvant therapy and subsequent management, with a specific focus on the balance between oncological and functional outcomes.

Abstract
BACKGROUND AND PURPOSE It is uncertain whether local control is acceptable after preoperative radiotherapy and local excision (LE). An optimal preoperative dose/fractionation schedule has not yet been established. MATERIAL AND METHODS In a phase III study, patients with cT1-2N0M0 or borderline cT2/T3N0M0 < 4 cm rectal adenocarcinomas were randomised to receive either 5 × 5 Gy plus 1 × 4 Gy boost or chemoradiation: 50.4 Gy in 28 fractions plus 3 × 1.8 Gy boost and 5-fluorouracil with leucovorin bolus. LE was performed 6-8 weeks later. Patients with ypT0-1R0 disease were observed. Completion total mesorectal excision (CTME) was recommended for poor responders, i.e. ypT1R1/ypT2-3. RESULTS Of 61 randomised patients, 10 were excluded leaving 51 for analysis; 29 in the short-course group and 22 in the chemoradiation group. YpT0-1R0 was observed in 66% of patients in the short-course group and in 86% in the chemoradiation group, p = 0.11. CTME was performed only in 46% of patients with ypT1R1/ypT2-3. The median follow-up was 8.7 years. Local recurrence incidences and overall survival at 10 years were respectively for the short-course group vs. the chemoradiation group 35% vs. 5%, p = 0.036 and 47% vs. 86%, p = 0.009. In total, local recurrence at 10 years was 79% for ypT1R1/T2-3 without CTME. CONCLUSIONS This trial suggests that in the LE setting, both local recurrence and survival are worse after short-course radiotherapy than after chemoradiation. Because of the risk of bias, a confirmatory study is desirable. Lack of CTME is associated with an unacceptably high local recurrence rate.

Abstract
Transanal excision (TAE) with conventional retractors and transanal endoscopic microsurgery (TEM) are two well established minimally invasive surgical options for the treatment of selected rectal cancers. TEM is nowadays considered the standard of care for the transanal excision of rectal tumors, since it is associated with significantly better quality of excision and lower rates of recurrence than TAE. When compared with rectal resection and total mesorectal excision, TEM has lower postoperative morbidity and better functional outcomes, with similar long-term survival rates in selected early rectal cancers. More recently, transanal minimally invasive surgery (TAMIS) has been developed as an alternative to TEM. Possible benefits of TAMIS are under evaluation.

Abstract
BACKGROUND Local excision (LE) alone is associated with worse survival compared to radical surgery (RS) for T2 rectal cancer, but LE with additional chemoradiation (CRT) may improve outcomes. The objective of this study was to compare combined CRT and LE versus RS for T2 rectal cancer. METHODS The 2004-2014 National Cancer Database was queried for patients with T2N0M0 rectal cancer undergoing LE with neoadjuvant(NA-CRT + LE) or adjuvant(LE + Adj-CRT) CRT, or RS. The main outcome was 5-year overall survival (OS). Cox proportional hazards was used to determine the independent effect of treatment on OS. RESULTS A total of 4822 patients were included (4367 RS, 242 CRT + LE, 213 LE + Adj-CRT). Mean follow-up was 48.6 (SD28.5) months. There were no differences in patient characteristics, but more high-risk features in the LE + Adj-CRT group. There were no differences in 90-day mortality. Five-year OS was similar (RS 77.4% vs. CRT + LE 76.1% vs. LE + Adj-CRT 79.7%, p = 0.786). Older age, male gender, and higher Charlson score were independently associated with worse OS, whereas treatment type was not. If 90-day mortality was excluded, LE + Adj-CRT was independently associated with worse OS compared to RS. CONCLUSIONS CRT with LE for T2N0M0 rectal cancer was not associated with worse OS compared to RS, and may be a viable treatment modality.

Abstract
BACKGROUND Little is known about anorectal function and quality of life after chemoradiation followed by local excision, which is an alternative to total mesorectal excision for selected patients with early rectal cancer. OBJECTIVE The purpose of this study was to prospectively assess anorectal function and health-related quality of life of patients with T2N0 rectal cancer who were treated with an alternative approach. DESIGN This was a prospective, phase II trial. SETTINGS The study was multicentric (American College of Surgeons Oncology Group trial Z6041). INTERVENTIONS Patients with stage cT2N0 rectal adenocarcinomas were treated with an oxaliplatin/capecitabine-based chemoradiation regimen followed by local excision. MAIN OUTCOME MEASURES Anorectal function and quality of life were assessed at enrollment and 1 year postoperatively with the Fecal Incontinence Severity Index, Fecal Incontinence Quality of Life scale, and Functional Assessment of Cancer Therapy-Colorectal Questionnaire. Results were compared, and multivariable analysis was performed to identify predictors of outcome. RESULTS Seventy-one patients (98%) were evaluated at enrollment and 66 (92%) at 1 year. Compared with baseline, no significant differences were found on Fecal Incontinence Severity Index scores at 1 year. Fecal Incontinence Quality of Life results were significantly worse in the lifestyle (p < 0.001), coping/behavior (p < 0.001), and embarrassment (p = 0.002) domains. There were no differences in the Functional Assessment of Cancer Therapy overall score, but the physical well-being subscale was significantly worse and emotional well-being was improved after surgery. Treatment with the original chemoradiation regimen predicted worse depression/self-perception and embarrassment scores in the Fecal Incontinence Quality of Life, and male sex was predictive of worse scores in the Functional Assessment of Cancer Therapy overall score and trial outcome index. LIMITATIONS Small sample size, relatively short follow-up, and absence of information before cancer diagnosis were study limitations. CONCLUSIONS Chemoradiation followed by local excision had minimal impact on anorectal function 1 year after surgery. Overall quality of life remained stable, with mixed effects on different subscales. This information should be used to counsel patients about expected outcomes.

Abstract
BACKGROUND Local excision for rectal cancer is expected to offer a better functional outcome than conventional surgery. The aim of the present study was to compare quality of life and bowel function in patients with rectal cancer who underwent either local excision or conventional surgery after chemoradiotherapy. METHODS This was a retrospective multicentre study. Patients who underwent local excision were compared with those who had mesorectal excision. Quality of life and bowel function were investigated using validated questionnaires (European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, EORTC QLQ-CR29 and Memorial Sloan-Kettering Cancer Center Bowel Function Instrument) at a median follow-up of 49 (range 13-95) months. Further analysis was undertaken of data from patients who underwent local excision alone compared with those requiring subsequent radical surgery. Statistical significance was set at P < 0·010. RESULTS The mean constipation score was significantly better in the local excision group than in the mesorectal excision group (3·8 (95 per cent c.i. 0·3 to 7·2) versus 19·8 (12·1 to 27·4); P < 0·001). Compared with patients who underwent mesorectal excision, those who had local excision had less sensation of incomplete emptying (mean score 3·7 (3·4 to 4·0) versus 2·8 (2·5 to 3·1); P < 0·001) and second bowel movements within 15 min (mean score 3·6 (3·3 to 3·9) versus 3·0 (2·7 to 3·3); P = 0·006). Patients who underwent local excision alone scored better than those who had mesorectal excision, particularly for bowel function, who, in turn, scored better than patients requiring subsequent radical surgery following local excision. CONCLUSION Patients who underwent local excision had a better quality of life and bowel function than those who underwent mesorectal excision.

Abstract
AIM Local excision (LE) is emerging as a treatment option for rectal cancer responding well to chemoradiation. However, it does not address the mesorectal nodal burden. We aimed to identify the factors influencing nodal positivity and subsequently defined a low-risk group by including only patients at low risk. METHOD A single-centre, retrospective database analysis was carried out of patients with radically resected rectal cancer after neoadjuvant chemoradiation. RESULTS This study included 524 patients with predominantly low rectal tumours. Nodal positivity among ypT0, T1 and T2 groups was 14.7%, 28% and 30%, respectively. Multivariate analysis with stepwise logistic regression identified the following low-risk features: age ≥ 40 years, nonsignet ring cell carcinoma (SRCC) histology and pathological complete response (pCR). Sixty-nine patients fulfilling all three criteria were analysed and the nodal positivity was found to be 10.1%, which implies that, if these patients had been selected for LE, one in 10 would have had positive mesorectal nodes. CONCLUSION Even in patients with low-risk criteria (pCR, non-SRCC histology and age ≥ 40 years), the residual positive nodal disease burden is 10%. Whether this high incidence of residual nodal disease translates into a similar risk of locoregional recurrence if an organ-preservation strategy is adopted is unclear.

Abstract
BACKGROUND Organ-preserving strategies have been considered for patients with distal rectal cancer and complete or near-complete response to neoadjuvant chemoradiation to avoid the functional consequences of radical surgery. Transanal endoscopic microsurgery and no immediate surgery (watch and wait) have been considered in selected patients. OBJECTIVE The aim of this study is to compare anorectal function following these 2 organ-preserving strategies (transanal endoscopic microsurgery and watch and wait) for rectal cancer with complete or near-complete response to neoadjuvant chemoradiation. DESIGN This study is based on the comparison of prospectively collected data. SETTINGS This study was conducted at a single center. PATIENTS Consecutive patients with distal rectal cancer undergoing neoadjuvant chemoradiation (50.4-54 Gy and 5-fluorouracil-based chemotherapy) were prospectively studied. Patients with complete clinical response were managed by watch and wait. Patients with near-complete response (≤3 cm, ycT1-2N0) were managed by transanal endoscopic microsurgery. MAIN OUTCOME MEASURES Functional outcomes were determined by anorectal manometry and Fecal Incontinence Index and Quality of Life assessment. RESULTS Two groups of patients were included in the study. Twenty-nine patients with near-complete response undergoing transanal endoscopic microsurgery and 53 with complete response after watch and wait were assessed. Baseline features were similar between groups. Patients undergoing transanal endoscopic microsurgery had worse resting/squeeze pressures (p = 0.004) and rectal capacity (p = 0.002). In addition, their incontinence scores (2.3 vs. 6.5; p < 0.001) and quality-of-life questionnaire responses (in all domains; p ≤ 0.01) were significantly worse in comparison with patients undergoing watch and wait. LIMITATIONS This study was limited by the small sample size and the absence of baseline anorectal function information. CONCLUSIONS Nonoperative management of patients with complete clinical response following chemoradiation results in better anorectal function in comparison with patients with near-complete response managed by transanal endoscopic microsurgery. In the absence of clinically detectable residual cancer, this latter approach may result in significant worsening of anorectal function.

Abstract
A significant part of rectal cancer survivors will experience urogenital dysfunction induced by the treatment. Significant progress has been made in order to improve the total mesorectal technique through different approaches (open, laparoscopic, robotic, transanal). Rectal cancer surgery is technically difficult notably deep in the pelvis, and therefore the most frequent cause of the postoperative dysfunction is the surgical nerve damage of the autonomic nerves at this level. The main objectives of these efforts were to obtain maximal oncological results and to achieve better functional outcomes including less postoperative urogenital dysfunctions. Our purpose was to build a comprehensive review of the existing literature data regarding this issue from past to present.

Abstract
For rectal cancers, the current standard of care consists of chemoradiation followed by radical surgery with total mesorectal excision. Oncologic results are good, especially regarding local recurrence rates, but at the cost of high morbidity rates and poor anorectal, urinary and sexual function results. Since chemoradiation yields 15 to 25% pathological complete response, the role of radical surgery is questioned for patients presenting with good response after chemoradiation and two organ preservation strategies have been offered: watch and wait strategy and local excision strategy. The aim of this review is to give the results of organ preservation after chemoradiotherapy series and to highlight different questions regarding initial patient's selection, complete clinical response definition, risk of mesorectal nodal involvement, follow-up modalities as well as oncologic and functional results.

Abstract
With the introduction of population screening initiatives, more patients may be amenable to local, transanal excision (LE) of early-stage rectal cancer. The most important drawback of LE is the risk of understaging node-positive disease. The most powerful predictors of node-positive disease are lymphatic invasion, submucosal invasion depth and width, tumor budding and poor differentiation. Therefore, LE should be reserved for low-risk T1 tumors in those reluctant or unable to undergo major surgery. Neoadjuvant chemoradiation followed by LE for T2 tumors allows adequate local control, and is currently being compared with anterior resection alone in randomized trials. A mere watchful waiting approach has been proposed in clinical complete responders to chemoradiation. However, given the very poor accuracy of current imaging modalities to predict a true pathological complete response, this strategy should not be offered outside of well-controlled trials.

Abstract
Improved treatment strategies have eliminated local control as the major problem in rectal cancer. With increasing awareness of long-term toxic effects in survivors of rectal cancer, organ-preservation strategies are becoming more popular. After chemoradiotherapy, both watchful waiting and local excision are used as possible alternatives for radical surgery. Although these seem attractive strategies, many issues about the safety of organ preservation remain. Additionally, radiotherapy strategies are mainly aimed at intermediate and high-risk rectal tumours, and adaptation of this standard practice for a completely new treatment indication has yet to start. This Review will discuss the options and problems of organ preservation, and address the research questions that need to be answered in the coming years, with a specific focus on radiotherapy.
