[PMID: 30360998 DOI: 10.1016/j.radonc.2018.10.007] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Revised: 09/18/2018] [Accepted: 10/08/2018] [Indexed: 11/28/2022]
Abstract
PURPOSE We investigated the efficacy and safety of carbon-ion radiotherapy (C-ion RT) for locally recurrent rectal cancer (LRRC). PATIENTS AND METHODS Data from patients with LRRC treated with C-ion RT from November 2003 to December 2014 at three institutions were retrospectively analyzed. The endpoints of this clinical trial were overall survival (OS), local control (LC), and acute/late toxicity. RESULTS A total of 224 patients' data were collected. The prescribed dose was 70.4 Gy (relative biological effectiveness [RBE]-weighted absorbed dose) or 73.6 Gy (RBE) in 16 fractions. The median follow-up period from the initiation of C-ion RT was 62 months (range 6-169 months). The OS rates were 73% (95% confidence interval [CI], 67%-79%) at 3 years and 51% (95%CI 44%-58%) at 5 years. The LC rates were 93% (95%CI 88%-96%) at 3 years, and 88% (95%CI 82%-93%) at 5 years. Grade 3 acute toxicity was observed in three patients: gastrointestinal toxicity (n = 1) and pelvic infection (n = 2). Grade 3 late toxicity was observed in 12 patients: skin reaction (n = 2), gastrointestinal toxicity (n = 2), neuropathy (n = 1), and pelvic infection (n = 7). There was no grade 4 or 5 acute or late toxicity. CONCLUSIONS This first multi-institutional analysis of C-ion RT for LRRC indicated relatively favorable outcomes with limited toxicities.

Transperineal retropubic approach in total pelvic exenteration for advanced and recurrent colorectal and anal cancer involving the penile base: technique and outcomes. Tech Coloproctol 2018; 22:663-671. [PMID: 30306276 DOI: 10.1007/s10151-018-1852-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Accepted: 09/08/2018] [Indexed: 01/21/2023]
Abstract
BACKGROUND Complete pathological resection of locally advanced and recurrent anorectal cancer is considered the most important determinant of survival outcome. Involvement of the retropubic space with cancer threatening or involving the penile base poses specific challenges due to the potential for margin involvement and blood loss from the dorsal venous plexus. In the present study we evaluate a new transperineal surgical approach to excision of anterior compartment organs involved or threatened by cancer which facilitates exposure and visualisation of the bulbar urethra and the deep vein of the penis caudal to the retropubic space and penile base. METHODS A retrospective study was performed on male patients with tumour extension into the penile base treated at our institution using the transperineal surgical approach. Descriptive data for patient demographics, radiology, operative details, postoperative histology, complications and outcomes were collated. RESULTS Ten male patients with tumour extension into the penile base were identified. Two patients had recurrent anal cancer, 6 had locally advanced primary rectal cancer and 2 had recurrent rectal cancer. All patients had exenterative surgery with excision of the penile base utilising the transperineal approach. All patients had R0 resection. No local recurrence developed after a median follow up period of 15 months. CONCLUSIONS The transperineal approach to the penile base and retropubic space allows for high rates of R0 resection margin status with direct visualisation of the dorsal venous plexus, thereby minimising blood loss. In our experience, this technique is the preferred approach to excision of cancers threatening and involving the penile base and also for most male patients requiring total pelvic exenteration.

Abstract
PURPOSE Radical management of locally recurrent rectal cancer (LRRC) can lead to prolonged survival. This study aims to assess outcomes and identify prognostic factors for patients with LRRC treated using a multimodality treatment protocol. METHODS An analysis of a prospectively maintained institutional database of consecutive patients who underwent radical surgical resection for LRRC was performed. Potential prognostic factors were investigated using a Cox proportional hazards model. RESULTS Ninety-eight patients were included in this study. A multimodality approach was taken in the majority, including preoperative chemoradiation (78%), intraoperative radiation therapy (47%) and adjuvant chemotherapy (41%). Extended resection was performed where required: bone resection (34%) and lateral pelvic sidewall dissection (31%). The rate of R0 resection was 66%. Estimated rates of 5-year overall survival (OS) and progression-free survival (PFS) were 41.8% (95% CI 32.5-53.7) and 22.5% (95% CI 15.3-33.1). On multivariate analysis, stage III disease at initial primary surgery, a positive margin at initial primary surgery, synchronous or previously resected oligometastases, a lateral or sacral invasive-type pelvic recurrence and the requirement for IORT all predicted for inferior PFS (p < 0.05). Eleven percent of patients subsequently underwent further pelvic surgery for pelvic re-recurrence and had an estimated 5-year OS rate of 54.5% (95% CI 29.0-100.0) from repeat surgery. CONCLUSIONS Radical multimodality management of LRRC leads to prolonged survival in approximately 40% of patients. Those with sacral or lateral invasive-type recurrence or oligometastatic disease have inferior outcomes and further research is needed to optimise treatment for these groups.

Abstract
BACKGROUND Over one-third of primary rectal cancers are locally advanced at diagnosis, and local recurrence of rectal cancer occurs at a rate of 3-10% following primary curative resection. Extended resectional surgery, including pelvic exenteration, is the only proven therapy with curative potential in the treatment of these cancers along with many other pelvic malignancies. A microscopically clear resection margin (R0 resection) is the predominant prognostic factor affecting overall and disease-free survival. The extent and complexity of surgery required to achieve an R0 resection is associated with significant risk of morbidity and mortality. The aim of this paper is to show that pelvic exenterations can be performed with acceptable oncological and safe perioperative results in an appropriately resourced specialist centre. METHODS Data was collected retrospectively for 61 consecutive patients treated between June 2012 and February 2017. This included patient demographics, tumour characteristics, operative, clinical and histological data, length of hospital stay, morbidity and mortality data. RESULTS A total of 61 patients underwent surgery. Median age was 57 years (range 27-78 years). Median length of stay was 41 days (range 6-288 days). Median operative time was 624 min (range 239-1035 min); 30-day mortality was 3.3% (n = 2). Resection rates were 91.5% - R0, 6.8% - R1 and 1.7% - R2 resections. Histologically, 86.9% - adenocarcinomas, 3.3% - squamous cell carcinomas and 9.8% - represented by leiomyosarcoma, melanoma, myxoid chondrosarcoma, non-neoplastic processes and undifferentiated carcinoma. CONCLUSION Our experience confirms that radical resectional pelvic surgery can be safely performed with acceptable results during the establishment phase of a dedicated tertiary service.

Abstract
INTRODUCTION Pelvic exenteration (PE) offers the best chance of cure for locally advanced primary or recurrent pelvic organ malignancies invading adjacent organs. The aims of this study were to analyse results for any pelvic exenteration that includes rectal resection and the analysis of results of fecal and urinary reconstruction. METHOD From January 2000 to April 2014, 111 PE with rectal resection for any pelvic cancer were analysed retrospectively at two national tertiary referral centers. RESULTS Thirty-six colorectal anastomosis were performed. Urologic reconstructions performed were 30 double barrelled wet colostomy (DBWC), 14 Bricker ileal conduit (BIC), and 2 ureterocutaneostomies. Postoperative complications occurred in 71 patients (64%). Six deaths (5.4%) occurred within 30 postoperative days. Five-year overall survival following R0 resection was 62.6%; R1: 42.7%; R2: 24.2% (P=.018). The resection margin status was associated with overall survival, local recurrence and distant recurrence. CONCLUSION Pelvic exenterations for any cause need to be performed in referral centers and by specialized surgeons. Anastomosis after modified supralevator pelvic exenteration for ovarian cancer, is safe. DBWC can be considered a valid option for urologic reconstruction. The most important prognostic factor after pelvic exenteration for malignant pelvic tumors is the status of surgical margins.

Abstract
Advanced primary and recurrent colorectal cancer can be successfully treated by experienced, dedicated centers delivering good outcomes with low mortality and morbidity. Development and implementation of a comprehensive referral pathway is to be encouraged. Multidisciplinary team management is essential in the management of this complex group of patients and is associated with significantly more complete preoperative evaluation and more accurate provision of patient information, as well as improved access to the most appropriate individualized management plan. A structured selection process can improve outcomes through standardized approaches to service delivery to provide the highest quality of care.

Abstract
BACKGROUND The influence of postoperative infectious complications, such as anastomotic leakage, on survival has been reported for various cancers, including colorectal cancer. However, it remains unclear whether intra-abdominal/pelvic inflammation after radical surgery for locally recurrent rectal cancer is relevant to its prognosis. OBJECTIVE The purpose of this study was to evaluate factors associated with survival after radical surgery for locally recurrent rectal cancer. DESIGN The prospectively collected data of patients were retrospectively evaluated. SETTINGS This study was conducted at a single-institution tertiary care cancer center. PATIENTS Between 1983 and 2012, patients who underwent radical surgery for locally recurrent rectal cancer with curative intent at the National Cancer Center Hospital were reviewed. MAIN OUTCOME MEASURES Factors associated with overall and relapse-free survival were evaluated. RESULTS During the study period, a total of 180 patients were eligible for analyses. Median blood loss and operation time for locally recurrent rectal cancer were 2022 mL and 634 minutes. Five-year overall and 3-year relapse-free survival rates were 38.6% and 26.7%. Age (p = 0.002), initial tumor stage (p = 0.03), pain associated with locally recurrent rectal cancer (p = 0.03), CEA level (p = 0.004), resection margin (p < 0.001), intra-abdominal/pelvic inflammation (p < 0.001), and surgery period (p = 0.045) were independent prognostic factors associated with overall survival, whereas CEA level (p = 0.01), resection margin (p = 0.002), and intra-abdominal/pelvic inflammation (p = 0.001) were associated with relapse-free survival. Intra-abdominal/pelvic inflammation was observed in 45 patients (25.0%). A large amount of perioperative blood loss was the only factor associated with the occurrence of intra-abdominal/pelvic inflammation (p = 0.007). LIMITATIONS This study was limited by its retrospective nature and heterogeneous population. CONCLUSIONS Intra-abdominal/pelvic inflammation after radical surgery for locally recurrent rectal cancer is associated with poor prognosis.

Abstract
Pelvic exenteration was first described by Alexander Brunschwig in 1948 in New York as a palliative procedure for recurrent carcinoma of the cervix. Because of initially high rates of morbidity and mortality, the practice of this ultraradical operation was largely confined to a small number of American centers for most of the 20 century. The post-World War II era saw advances in anaesthesia, blood transfusion, and intensive care medicine that would facilitate the evolution of more radical and heroic abdominal and pelvic surgery. In the last 3 decades, pelvic exenteration has continued to evolve into one of the most important treatments for locally advanced and recurrent rectal cancer. This review aimed to explore the evolution of pelvic exenteration surgery and to identify the pioneering surgeons, seminal articles, and novel techniques that have led to its current status as the procedure of choice for locally advanced and recurrent rectal cancer.

Abstract
OBJECTIVE The aim of this study was to assess resection margin status and its impact on survival after abdominoperineal excision and pelvic exenteration for primary or recurrent rectal cancer. SUMMARY OF BACKGROUND DATA Resection margin is important to guide therapy and to evaluate patient prognosis. METHODS A meta-analysis was performed to assess the impact of resection margin status on survival, and a regression analysis to analyze positive resection margin rates reported in the literature. RESULTS The analysis included 111 studies reporting on 19,607 participants after abdominoperineal excision, and 30 studies reporting on 1326 participants after pelvic exenteration. The positive resection margin rates for abdominoperineal excision were 14.7% and 24.0% for pelvic exenteration. The overall survival and disease-free survival rates were significantly worse for patients with positive compared with negative resection margins after abdominoperineal excision [hazard ratio (HR) 2.64, P < 0.01; HR 3.70, P < 0.01, respectively] and after pelvic exenteration (HR 2.23, P < 0.01; HR 2.93, P < 0.01, respectively). For patients undergoing abdominoperineal excision with positive resection margins, the reported tumor sites were 57% anterior, 15% posterior, 10% left or right lateral, 8% circumferential, 10% unspecified. A significant decrease in positive resection margin rates was identified over time for abdominoperineal excision. Although positive resection margin rates did not significantly change with the size of the study, some small size studies reported higher than expected positive resection margin rates. CONCLUSIONS Resection margin status influences survival and a multidisciplinary approach in experienced centers may result in reduced positive resection margins. For advanced anterior rectal cancer, posterior pelvic exenteration instead of abdominoperineal excision may improve resection margins.

Abstract
Considerable progress has been made in the management of patients with locally advanced or recurrent cancers of the pelvis over the past 60 years since the inception of pelvic exenteration. Early progress in pelvic exenteration was marred by the high surgical mortality and morbidity, which drew scepticism from the broader surgical community. Subsequent evolution in the procedure hinged on establishing surgical safety and a better understanding of outcome predictors. Surgical mortality from pelvic exenteration is now comparable to that of elective resection for primary colorectal cancers. The importance of a clear resection margin is also now well established in providing durable local control and predicting long-term survival that, in turn, has driven the development of novel surgical techniques for pelvic side wall resection, en bloc sacrectomy, and pubic bone resection. A tailored surgical approach depending on the location of the tumor with resection of contiguously involved organs, yet preserving uninvolved organs to minimize unnecessary surgical morbidity, is paramount. Despite improved surgical and oncological outcomes, surgical morbidity following pelvic exenteration remains high with reported complication rates ranging between 20% and 80%. Extended antibiotic prophylaxis and preemptive parenteral nutrition in the immediate postoperative period may reduce septic and nutritional complications. A high index of suspicion is needed in the early diagnosis and management of complications that may avoid prolonged duration of hospitalization. An acceptable quality of life has been reported among patients after pelvic exenteration. Further research into novel chemotherapy, immunotherapy, and reconstructive options are currently underway and are needed to further improve outcomes.

Abstract
AIM There is wide disparity in the care of patients with multivisceral involvement of rectal cancer. The results are presented of treatment of advanced and recurrent colorectal cancer from a centre where a dedicated multidisciplinary team (MDT) is central to the management. METHOD All consecutive MDT referrals between 2010 and 2014 were examined. Analysis was undertaken of the referral pathway, site, selection process, management decision, R0 resection rate, mortality/morbidity/Clavien-Dindo (CD) classification of morbidity, length of stay (LOS) and improvement of quality of life. RESULTS There were 954 referrals. These included locally advanced primary rectal cancer (LAPRC b-TME) (39.0%), rectal recurrence (RR) (22.0%), locally advanced primary colon cancer (LAPCC T3c/d-T4) (21.1%), colon cancer recurrence (CR) (12.4%), locally advanced primary anal cancer (LAPAC-failure of CRT/T3c/d-T4) (3.0%) and anal cancer recurrence (AR) (2.2%). Among these patients 271 operations were performed, 212 primary and 59 for recurrence. These included 16 sacrectomies, 134 total pelvic exenterations and 121 other multi-visceral exenterative procedures. An R0 resection (no microscopic margin involvement) was achieved in 94.4% and R1 (microscopic margin involvement) in 5.1%. In LAPRC b-TME the R0 rate was 96.1% and for RR it was 79%. The LOS varied from 13.3 to 19.9 days. RR operations had the highest morbidity (CD 1-2, 33.3%) and LAPRC operations had the highest rate of CD 3-4 complications (18.4%). Most (39.6%) of the referred patients were from other UK hospitals. CONCLUSION Advanced colorectal cancer can be successfully treated in a dedicated referral centre, achieving R0 resection in over 90% with low morbidity and mortality. Implementation of a standardized referral pathway is encouraged.

Abstract
BACKGROUND AND AIMS Evidence has shown that a positive resection margin (R1) is a key determinant of subsequent local recurrence and a poor prognostic factor in rectal cancer. The aim of this study was to evaluate the outcomes and prognosticators in patients with R1 resection of rectal cancer. MATERIAL AND METHODS Retrospective study of all patients operatively managed within our institution between April 2008 and April 2013 for rectal cancer. Baseline demographics and multiple outcome measures recorded. Overall survival (OS), disease-free survival (DFS) and recurrence were the primary outcome measures. RESULTS Overall, there were 306 primary rectal cancers. Seventy-six percent were grade T3/4 tumours. OS was 30 months. R1 rate was 16 % (48 patients). Thirty-one patients underwent APR and 17 AR. In patients who responded to neoadjuvant chemotherapy (NAC), overall survival was 55 months, with no extramural venous invasion (EMV) seen in this cohort. In non-responders OS was 29 months, with EMV in 48 %. In patients who did not receive NAC, OS was 23 months, with EMV in 74 %. EMV is a strong predictor for poor survival following R1 (p = 0.001). We also found a correlation between number of positive nodes and OS/DFS (p = 0.004). CONCLUSIONS In this small cohort of patients with R1 positive rectal cancers, response to NAC is the strongest predictor of poor overall and disease-free survival. In patients who respond to NAC, OS and DFS has been shown to be positive, with a reduced rate of EMV.

Abstract
Between 5% and 10% of patients with rectal cancer present with locally advanced rectal cancer (LARC), and 10% of rectal cancers recur after surgery, of which half are limited to locoregional disease only (locally recurrent rectal cancer). Exenterative surgery offers the best long-term outcomes for patients with LARC and locally recurrent rectal cancer so long as a complete (R0) resection is achieved. Accurate preoperative multimodal staging is crucial in assessing the potential operability of advanced rectal tumors, and resectability may be enhanced with neoadjuvant therapies. Unfortunately, surgical options are limited when the tumor involves the lateral pelvic sidewall or high sacrum due to the technical challenges of achieving histological clearance, and must be balanced against the high morbidity associated with resection of the bony pelvis and significant lymphovascular structures. This group of patients is usually treated palliatively and subsequently survival is poor, which has led surgeons to seek innovative new solutions, as well as revisit previously discarded radical approaches. A small number of centers are pioneering new techniques for resection of beyond-total mesorectal excision tumors, including en bloc resections of the sciatic notch and composite resections of the first two sacral vertebrae. Despite limited experience, these new techniques offer the potential for radical treatment of previously inoperable tumors. This narrative review sets out the challenges facing the management of LARCs and discusses evolving management options.

Abstract
Abstract
Background
The rising cost of healthcare is well documented. The purpose of this study was to determine the cost-effectiveness of pelvic exenteration (PE).
Methods
Consecutive patients referred for consideration of PE between 2008 and 2011 were recruited into a prospective non-randomized study that compared quality of life (QoL) between patients who did or did not undergo PE. Information on QoL and cost (in Australian dollars, AUD) was collected at baseline, during admission and up to 24 months after discharge. QoL data were converted into a utility-based measure. Quality-adjusted life-years (QALYs) were calculated. Bottom-up costing was performed. The incremental cost-effectiveness ratio (ICER) was calculated per life-year saved and per QALY.
Results
There were 174 patients with sufficient data for analysis. Of these, 139 underwent PE. R0 was achieved in 78·4 per cent of patients. The survival rate at 24 months after PE was 74·8 per cent compared with 43 per cent in those without exenteration (P = 0·001). Treatment costs were significantly higher for patients who had PE compared with those who did not (mean AUD 137 407 versus 79 174; P < 0·001). The ICER was AUD 124 147 (95 per cent c.i. 71 585 to 261 876) per life-year saved and AUD 227 330 (109 974 to 1 100 449) per QALY. Curative PE (R0) was found to be more cost-effective than non-curative PE (R1/R2), with an ICER of AUD 101 518 (60 105 to 200 428) versus 390 712 (74 368 to 82 256 739) per life-year saved.
Conclusion
Treatment of advanced pelvic cancers is expensive regardless of the treatment intent. For a cost difference of only AUD 58 000 (€38 264), PE offers a chance of cure, and improves survival and QoL.

Intraoperative radiotherapy with low energy photons in recurrent colorectal cancer: a single centre retrospective study. Contemp Oncol (Pozn) 2016; 20:52-7.

Abstract
AIM OF THE STUDY Intraoperative radiotherapy (IORT) may improve outcome of surgical treatment of recurrent colorectal cancer (CRC). The aim of this study is to determine the feasibility, safety and long-term results of surgical treatment of recurrent CRC with orthovolt IORT. MATERIAL AND METHODS Fifty-nine consecutive CRC patients with local recurrence (LR), undergoing surgery, were included in the retrospective analysis of prospectively collected data. The modified Wanebo classification was used to stage LR (Tr). Twenty-five (43%) patients received IORT using INTRABEAM(®) PRS 500. The complications were classified according to the Clavien-Dindo classification. RESULTS There were 32 males and 27 females, with a median age of 63 years. Multi-visceral resections were performed in 37 (63%) patients. Median hospitalization time after surgery with IORT was 7 days. One (1.7%) in-hospital postoperative death was reported. Grade 3/4 postoperative complications were found in 11 (19%) patients. Intraoperative radiotherapy had no effect on the postoperative hospitalization time, morbidity and mortality. Median survival after R0 resection was 32 months. Complete resection (R0), no synchronous liver metastases (M0), and no lateral and posterior pelvic wall involvement, were significant predictors of improved survival. Stage of LR was found to be an independent prognostic factor in the multivariate analysis (p = 0.03); Cox regression model). In patients with LR stage < Tr5, a 3-year overall survival (OS) rate was 52%. CONCLUSIONS Combination of surgical resection and orthovolt IORT is a safe and feasible procedure that does not increase the risk of postoperative complications or prolongs the hospital stay. Despite aggressive surgery supported by IORT, the advanced stage of LR is a limiting factor of long-term survival.

Abstract
In rectal cancer management, accurate staging by magnetic resonance imaging, neo-adjuvant treatment with the use of radiotherapy, and total mesorectal excision have resulted in remarkable improvement in the oncological outcomes. However, there is substantial discrepancy in the therapeutic approach and failure to adhere to international guidelines among different Greek-Cypriot hospitals. The present guidelines aim to aid the multidisciplinary management of rectal cancer, considering both the local special characteristics of our healthcare system and the international relevant agreements (ESMO, EURECCA). Following background discussion and online communication sessions for feedback among the members of an executive team, a consensus rectal cancer management was obtained. Statements were subjected to the Delphi methodology voting system on two rounds to achieve further consensus by invited multidisciplinary international experts on colorectal cancer. Statements were considered of high, moderate or low consensus if they were voted by ≥80%, 60-80%, or <60%, respectively; those obtaining a low consensus level after both voting rounds were rejected. One hundred and two statements were developed and voted by 100 experts. The mean rate of abstention per statement was 12.5% (range: 2-45%). In the end of the process, all statements achieved a high consensus. Guidelines and algorithms of diagnosis and treatment were proposed. The importance of centralization, care by a multidisciplinary team, adherence to guidelines, and personalization is emphasized.

Abstract
PURPOSE The location of locally recurrent rectal cancer (LRRC) may influence survival. This study examines factors affecting the location of LRRC, the effect of LRRC location on survival, and predictive factors for survival in patients with LRRC. METHODS Patients undergoing initial proctectomy and subsequent management of LRRC at the Cleveland Clinic (1980-2011) were included. Data regarding index surgery, LRRC, and survival were obtained from a prospectively maintained database. RESULTS One hundred and fifty-seven patients were identified with a mean follow-up 59.8 ± 50.1 months and time to LRRC of 31.7 ± 30.1 months. Sixty patients underwent surgery with curative intent. Anastomotic leak and retrieving less than 12 lymph nodes at index proctectomy were associated with posterior (P = 0.019) and lateral (P = 0.036) recurrences, respectively. Having an axial relative to an anterior, posterior, or lateral recurrence was associated with improved overall survival (P = 0.001). On multivariable analysis, undergoing primarily palliative treatment (OR, 5.2; 95 % confidence interval (CI), 3.2-8.4; P < 0.001), age at LRRC >60 years (OR, 1.9; 95 % CI, 1.3-2.7, P < 0.001), advanced primary tumour stage (OR, 1.5; 95 % CI, 1.1-2.1; P = 0.021), and anastomotic leak at index surgery (OR, 1.8; 95 % CI, 1.2-2.7; P = 0.008) were associated with reduced LRRC 5-year survival. CONCLUSIONS The current study suggests that features of the primary tumour and technical factors at the time of index proctectomy influence both the location of LRRC and survival.

Abstract
Since the advent of radiation therapy for rectal cancer, there has been continual investigation of advancing technologies and techniques that allow for improved dose conformality to target structures while limiting irradiation of surrounding normal tissue. For locally advanced disease, intensity modulated and proton beam radiation therapy both provide more highly conformal treatment volumes that reduce dose to organs at risk, though the clinical benefit in terms of toxicity reduction is unclear. For early stage disease, endorectal contact therapy and high-dose rate brachytherapy may be a definitive treatment option for patients who are poor operative candidates or those with low-lying tumors that desire sphincter-preservation. Finally, there has been growing evidence that supports stereotactic body radiotherapy as a safe and effective salvage treatment for the minority of patients that locally recur following trimodality therapy for locally advanced disease. This review addresses these topics that remain areas of active clinical investigation.

Abstract
AIM The surgical management of locally recurrent rectal cancer (LRRC) has become widely accepted to afford cure and improve quality of life in this subset of patients. Thus far, traditional surgical and oncological markers have been used to highlight the success of surgical intervention. The use of patient-reported outcomes, specifically health-related quality of life (HRQoL), is sparse in these patients. This may be in part due to the lack of well-designed, validated instruments. This study identifies HRQoL issues relevant to patients undergoing surgery for LRRC, with the aim of developing a conceptual framework of HRQoL specific to LRRC to enable measurement of patient-reported outcomes in this cohort of patients. METHOD Qualitative focus groups were undertaken at two institutions to identify relevant HRQoL themes. The principles of thematic content analysis were used to analysis data. NViVo10 was used to analyse data. RESULTS Twenty-one patients participated in six consecutive focus groups. Two patterns of themes emerged related to HRQoL and healthcare service delivery and utilization. Identified themes related to HRQoL included symptoms, sexual function, psychological impact, role and social functioning and future perspective. Under healthcare service and delivery and utilization the subdomain of disease management, treatment expectations and healthcare professionals were identified. CONCLUSION This is the first qualitative study undertaken exclusively in patients with LRRC to ascertain relevant HRQoL outcomes. The impact of LRRC on patients is wide-ranging and extends beyond traditional HRQoL outcomes. The study operationalizes the identified outcomes into a conceptual framework, which will provide the basis for the development of a LRRC-specific patient-reported outcome measure.

Abstract
BACKGROUND Involvement of the lateral compartment remains a relative or absolute contraindication to pelvic exenteration in most units. Initial experience with exenteration in the authors' unit produced a 21 per cent clear margin rate (R0), which improved to 53 per cent by adopting a novel technique for en bloc resection of the iliac vessels and other side-wall structures. The objective of this study was to report morbidity and oncological outcomes in consecutive exenterations involving the lateral compartment. METHODS Patients undergoing pelvic exenteration between 1994 and 2014 were eligible for review. RESULTS Two hundred consecutive patients who had en bloc resection of the lateral compartment were included. R0 resection was achieved in 66·5 per cent of 197 patients undergoing surgery for cancer and 68·9 per cent of planned curative resections. For patients with colorectal cancer, a clear resection margin was associated with a significant overall survival benefit (P = 0·030). Median overall and disease-free survival in this group was 41 and 27 months respectively. Overall 1-, 3- and 5-year survival rates were 86, 46 and 35 per cent respectively. No predictors of survival were identified on univariable analysis other than margin status and operative intent. Excision of the common or external iliac vessels or sciatic nerve did not confer a survival disadvantage. CONCLUSION The continuing evolution of radical pelvic exenteration techniques has seen an improvement in R0 margin status from 21 to 66·5 per cent over a 20-year interval by routine adoption of a more lateral anatomical plane. Five-year overall survival rates are comparable with those for more centrally based tumours.

Abstract
The growth of residual tumor cells may cause postoperative colorectal anastomotic recurrence, which mainly exists in the intestine; however, rectal washout can significantly reduce the number of free tumor cells in the intestinal cavity and decrease the local recurrence rate. Clinical application of rectal washout has been tried in operation, but the effect remains controversial. This paper mainly introduces the method of rectal washout, washout fluid type, amount of washout fluid, relation of rectal washout with local recurrence, with emphasis on the influence of reasonable application of rectal washout on prognosis and recurrence of rectal cancer after surgery.

Abstract
Surgical resection is the most effective therapy for locally recurrent rectal cancer (LRRC); however, it often necessitates invasive procedures that may lead to major complications. Particle beam radiotherapy (RT), including carbon ion RT (C-ion RT) and proton beam RT, is a promising new modality that exhibits considerable efficacy against various types of human cancer. C-ion RT reportedly offers a therapeutic alternative for LRRC. In the present study, we describe three cases of LRRC treated by particle beam RT. In all the cases, LRRC was diagnosed by computed tomography, magnetic resonance imaging and positron emission tomography imaging. No serious adverse effects were observed during RT. One patient experienced re-recurrence of LRRC, but survived for 6 years following particle beam RT; the second patient remains recurrence-free after a 2-year follow-up; and the third patient has developed recurrence at different sites in the pelvis but, to date, has survived for 4 years following particle beam RT. Therefore, LRRC was controlled by particle beam RT in two of the three cases, suggesting that particle beam RT is a safe alternative treatment for patients with LRRC.

Abstract
BACKGROUND Pelvic exenteration is a potentially curative treatment for locally advanced primary rectal cancer. Previous studies have been limited by small sample sizes and heterogeneous data. A consecutive series of patients was studied to identify the clinicopathological determinants of survival. METHODS All patients undergoing pelvic exenterative surgery for primary rectal cancer (1992-2014) at this hospital were analysed. The primary outcome measure was 5-year overall survival. Secondary endpoints included length of hospital stay, complication rate, 30-day mortality and disease recurrence rate. Statistical analysis was performed using Kaplan-Meier and Cox regression analysis. RESULTS A total of 174 patients with a median age of 65 (range 31-90) years were included. Ninety-six patients underwent posterior pelvic exenteration and 78 had total pelvic exenteration. Median follow-up was 48 (range 1-229) months. Two patients (1.1 per cent) died within 30 days of surgery and 16.1 per cent returned to the operating theatre. The 5-year survival rate following complete resection (R0) was 59.3 per cent. In univariable analysis, adverse survival was associated with advanced age (P = 0.003), metastatic disease (P = 0.001), pathological node status (P = 0.001), circumferential resection margin (P = 0.001), local recurrence (P = 0.015) and the need for neoadjuvant therapy (P = 0.039). CONCLUSION Pelvic exenteration is an aggressive treatment option with a high morbidity rate that provides favourable long-term outcomes in patients with locally advanced primary rectal cancer.

CAPIRI-IMRT: a phase II study of concurrent capecitabine and irinotecan with intensity-modulated radiation therapy for the treatment of recurrent rectal cancer. Radiat Oncol 2015; 10:57. [PMID: 25889149 PMCID: PMC4353448 DOI: 10.1186/s13014-015-0360-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2014] [Accepted: 02/16/2015] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND This study investigated the local effect and acute toxicity of irinotecan and capecitabine with concurrent intensity-modulated radiation therapy (IMRT) for the treatment of recurrent rectal cancer without prior pelvic irradiation. METHODS Seventy-one patients diagnosed with recurrent rectal cancer who did not previously receive pelvic irradiation were treated in our hospital from October 2009 to July 2012. Radiotherapy was delivered to the pelvis, and IMRT of 45 Gy (1.8 Gy per fraction), followed by a boost of 10 Gy to 16 Gy (2 Gy per fraction), was delivered to the recurrent sites. The concurrent chemotherapy regimen was 50 mg/m(2) irinotecan weekly and 625 mg/m(2) capecitabine twice daily (Mon-Fri). Radical surgery was recommended for medically fit patients without extra-pelvic metastases. The patients were followed up every 3 months. Tumor response was evaluated using CT/MRIs according to the RECIST criteria or postoperative pathological findings. NCI-CTC 3.0 was used to score the toxicities. RESULTS Forty-eight patients (67.6%) had confirmed recurrent rectal cancer without extra pelvic metastases, and 23 patients (32.4%) had extra pelvic metastases. Fourteen patients (19.7%) underwent radical resections (R0) post-chemoradiation. A pathologic complete response was observed in 7 of 14 patients. A clinical complete response was observed in 4 patients (5.6%), and a partial response was observed in 22 patients (31.0%). Only 5 patients (7.0%) showed progressive disease during or shortly after treatment. Of 53 symptomatic patients, clinical complete and partial symptom relief with chemoradiation was achieved in 56.6% and 32.1% of patients, respectively. Only 2 patients (2.8%) experienced grade 4 leukopenia. The most common grade 3 toxicity was diarrhea (16 [22.5%] patients). The median follow-up was 31 months. The cumulative local progression-free survival rate was 74.2% and 33.9% at 1 and 3 years after chemoradiation, respectively. The cumulative total survival rate was 80.1% and 36.5% at 1 and 3 years after chemoradiation, respectively. CONCLUSIONS This study revealed that concurrent irinotecan and capecitabine with IMRT significantly relieves local symptoms and exhibits promising efficacy with manageable toxicities in recurrent rectal cancer without prior pelvic irradiation. Improving the rate of R0 resections will be investigated in a future study.

Abstract
BACKGROUND AND OBJECTIVES When surgery is not adequate or feasible, stereotactic body radiotherapy (SBRT) reirradiation has been used for recurrent cancers. We report the outcomes of a series of patients with pelvic recurrences from colorectal cancer reirradiated with SBRT. METHODS The Cyberknife(TM) Robotic Stereotactic Radiosurgery system with fiducial based real time tracking was used. Patients were followed with imaging of the pelvis. RESULTS Four women and 14 men with 22 lesions were included. The mean dose was 25 Gy in median of five fractions. The mean prescription isodose was 77%, with a median maximum dose of 32.87 Gy. There were two local failures, with a crude local control rate of 89%. The median overall survival was 43 months. One patient had small bowel perforation and required surgery (Grade IV), two patients had symptomatic neuropathy (1 Grade III) and one patient developed hydronephrosis from ureteric fibrosis requiring a stent (Grade III). CONCLUSIONS Local recurrence in the pelvis after modern combined modality treatment for colorectal cancer is rare. However it presents a therapeutic dilemma when it occurs; often symptomatic and eventually life threatening. SBRT can be a useful non-surgical modality to control pelvic recurrences after prior radiation for colorectal cancer.

Abstract
BACKGROUND Radiotherapy reduces local recurrence rates but is also capable of short- and long-term toxicity. It may also render treatment of local recurrence more challenging if it develops despite previous radiotherapy. OBJECTIVE This study examined the impact of radiotherapy for the primary rectal cancer on outcomes after pelvic exenteration for local recurrence. DESIGN We conducted a retrospective review of exenteration databases. SETTING The study took place at a quaternary referral center that specializes in pelvic exenteration. PATIENTS Patients referred for pelvic exenteration from October 1994 to November 2012 were reviewed. Patients who did and did not receive radiotherapy as part of their primary rectal cancer treatment were compared. MAIN OUTCOME MEASURES The main outcomes of interest were resection margins, overall survival, disease-free survival, and surgical morbidities. RESULTS There were 108 patients, of which 87 were eligible for analysis. Patients who received radiotherapy for their primary rectal cancer (n = 41) required more radical exenterations (68% vs 44%; p = 0.020), had lower rates of clear resection margins (63% vs 87%; p = 0.010), had increased rates of surgical complications per patient (p = 0.014), and had a lower disease-free survival (p = 0.022). Overall survival and disease-free survival in patients with clear margins were also lower in the primary irradiated patients (p = 0.049 and p < 0.0001). This difference in survival persisted in multivariate analysis that corrected for T and N stages of the primary tumor. LIMITATIONS This study is limited by its retrospective nature and heterogeneous radiotherapy regimes among radiotherapy patients. CONCLUSIONS Patients who previously received radiotherapy for primary rectal cancer treatment have worse oncologic outcomes than those who had not received radiotherapy after pelvic exenteration for locally recurrent rectal cancer.

Abstract
BACKGROUND Tumor lesions in previously irradiated area may have a less favorable response to chemotherapy compared to tumor sites outside the radiation field. The aim of the present study was to evaluate the response to chemotherapy of locally recurrent rectal cancer (LRRC) within the previous radiation field compared to the response of distant metastases outside the radiation field. PATIENTS AND METHODS All patients with LRRC referred between 2000 and 2012 to our tertiary university hospital were reviewed. The response to chemotherapy of LRRC within previously irradiated area was compared to the response of synchronous distant metastases outside the radiation field according to the Response Evaluation Criteria in Solid Tumors (RECIST). RESULTS Out of 363 cases with LRRC, 29 previously irradiated patients with distant metastases were treated with chemotherapy and eligible for analysis. Twenty-six patients (89 %) suffered a first recurrence and three patients (11 %) a second recurrence. These patients were followed with a median of 22 months (IQR, 9-40 months) and had a median survival of 33 months (IQR, 14-42). In 23 patients (79 %), the local recurrence showed stable disease, but the overall response rate of the local recurrences in the previously irradiated area was significantly lower than the response rate of distant metastases outside the radiation field (10 vs. 41 %,p = 0.034). CONCLUSIONS Previously irradiated patients with LRRC have a lower response rate to chemotherapy of the local recurrence within the radiation field compared to the response rate of distant metastases outside the radiation field. This suggests that chemotherapy for local palliation may not have the desired effect.

Abstract
The standardization of surgical techniques supplemented with appropriate neoadjuvant chemoradiation has led to the decline in local recurrence rates of rectal cancer (LRRC) from 25-50% to 5-10%. The outcomes reported for surgical intervention in LRRC is encouraging, however, a number of controversies exist especially in the ultra-advanced and palliative setting. Incorporating health-related quality of life (HRQoL) outcomes in this field could supplement traditional clinical endpoints in assessing the effectiveness of surgical intervention in this cohort. This review aimed to identify the HRQOL themes that might be relevant to patients with LRRC. A systematic review was undertaken to identify all studies reporting HRQoL in LRRC. Each study was evaluated with regards to its design and statistical methodology. A meta-synthesis of qualitative and quantitative studies was undertaken to identify relevant HRQoL themes. A total of 14 studies were identified, with 501 patients, with 80% of patients undergoing surgery. HRQoL was the primary endpoint in eight studies. Eight themes were identified: physical, psychological and social impact, symptoms, financial and occupational impact, relationships with others, communication with healthcare professionals and sexual function. The impact on HRQoL is multifactorial and wide ranging, with a number of issues identified that are not included in current measures. These issues must be incorporated into the assessment of HRQoL in LRRC through the development of a validated, disease-specific tool.

Abstract
AIM The influence of the height of rectal cancer from the anal verge on the oncological outcome is controversial. This study aimed to determine the influence of the height of the tumour on the survival of patients treated in a specialized rectal cancer unit. METHOD Patients undergoing surgery for primary rectal cancer from 2006 to 2013 were identified from a prospectively maintained rectal cancer database. Those requiring total or multicompartmental pelvic exenteration were excluded. Low cancer was defined as tumour < 5 cm from the anal verge, as assessed by endoscopy and/or digital rectal examination. The primary outcome was 3-year disease-free survival (DFS). RESULTS Of 340 patients, 203 (59.7%) had low cancer. There were 302 (89%) restorative and 38 (11%) nonrestorative procedures. The rate of positive circumferential resection margin was similar for low compared with high cancer (3.4% vs 2.9%, P = 1.0) and for restorative compared with nonrestorative procedures in low cancer only (3.0% and 5.3%, P = 0.619). Low compared with high anterior resection was associated with increased anastomotic leakage (8.5% vs 2.2%, P = 0.023). Three-year DFS was similar for low and high resection (82% vs 86%, P = 0.305) and between restorative vs nonrestorative procedures in low cancer only (88% vs 77%, P = 0.215). In an adjusted model, low height did not lead to worse survival outcome (3-year DFS hazard ratio 0.54, 95% CI 0.24-1.24, P = 0.147). CONCLUSION With careful planning and a multidisciplinary approach, equivalent oncological outcome can be achieved for patients with rectal cancer who undergo curative surgery regardless of differences in tumour characteristics, location and operation performed.

Abstract
BACKGROUND Many patients with locally recurrent rectal cancer receive radiotherapy for the treatment of the primary tumour. It is unclear whether reirradiation is safe and effective when a local recurrence develops. The aim of this study was to evaluate the toxicity and oncological outcome of reirradiation in patients with locally recurrent rectal carcinoma. METHODS From March 1994 until December 2013, data on patients with locally recurrent rectal cancer (without distant metastasis) were entered into a database. Patients were reirradiated with a reduced dose of 30 Gy and received an intraoperative electron radiotherapy boost during surgery. Morbidity associated with radiotherapy, postoperative complications and oncological outcome were evaluated. RESULTS Clear margins (R0) were obtained in 75 (55·6 per cent) of the 135 patients who were reirradiated. Forty-six patients developed serious postoperative complications and the 30-day mortality rate was 4·6 per cent. Multivariable analysis showed that margin status was the main factor influencing oncological outcome (hazard ratio for overall survival 2·51 for R1 and 3·19 for R2 versus R0 resection; both P < 0·001). There was no significant difference in survival between the reirradiated group and a group of 113 patients who had full-course irradiation (5-year overall survival rate 34·1 and 39·1 per cent respectively; P = 0·278). Both reirradiation and full-course irradiation were associated with better survival than no irradiation in a historical control group of 24 patients (5-year overall survival rate 23 per cent; P = 0·225 and P = 0·062). CONCLUSION Reirradiation (with concomitant chemotherapy) has few side-effects and complements radical resection of recurrent rectal cancer.

Abstract
OBJECTIVE The outcome of pelvic exenteration was compared in patients with locally advanced primary (LAP) cancer and recurrent rectal cancer (RRC). BACKGROUND There are few reports comparing the results of pelvic exenteration for primary advanced rectal cancer and RRC. METHODS Consecutive patients undergoing pelvic exenteration between 2006 and 2011 were identified from a prospectively maintained database. The main endpoints were 3-year disease-free survival (DFS) and local recurrence-free survival (LRFS). RESULTS Of 100 exenterative operations, 55 were for LAP cancer and 45 for RRC. Exenteration of 1 pelvic compartment was required in 30 cases, 2 compartments in 49 cases, and 3 of 4 compartments in 21 cases. R0, R1, and R2 resections were achieved in 78, 15, and 7 cases, respectively. R0 rates were significantly higher in LAP cancer than in RRC (91% vs 62%, P = 0.001). Three-year DFS for R0, R1, and R2 resections was 67%, 49%, and 0%, respectively (P < 0.001). For R0 resections only, DFS in LAP cancer was 76% and 57% in RRC (P = 0.212). On multivariate analysis, a positive resection margin (hazard ratio, 4.04; P < 0.001) and positive lymph node staging (hazard ratio, 2.43; P = 0.022) were significant predictors of reduced DFS. Three-year LRFS for R0 resection was 86% for LAP cancer and 84% for RRC (P = 0.817). On multivariate analysis, only a positive resection margin was a significant predictor of reduced LRFS (hazard ratio, 5.48; P = 0.002). CONCLUSIONS Resection margin status is more important than primary or recurrent cancer in predicting long-term outcome.

Abstract
AIM Extramural vascular invasion (EMVI) has been proposed as an adverse prognostic indicator in colorectal cancer, although its use remains both variable and controversial. This study aimed to determine the survival effect of EMVI in T4 rectal cancer. METHOD Patients undergoing surgery with curative intent for primary T4 rectal cancer between 1971 and 2011 were included from two prospectively collected rectal cancer databases. The main end-point was 3-year survival. RESULTS From 1142 patients undergoing resection of rectal cancer during the study period, 126 (11.0%) had T4 rectal cancer and were included in the study group. Sphincter preservation was performed in 61 (48%) and a pathologically negative resection margin (R0) was achieved in 104 patients (82.5%). EMVI was present in 51 patients (40.5%) and was an independent predictor of positive lymph node status (adjusted odds ratio 2.66, P = 0.013). Considering all patients, EMVI was associated with reduced overall survival (P = 0.007) and disease-free survival (P = 0.002), but not local recurrence-free survival (P = 0.198). In only those undergoing R0 resection, EMVI predicted reduced disease-free survival with positive nodal status (P = 0.021); it did not predict survival with negative nodal status. CONCLUSION Overall, EMVI was a strong prognostic marker of survival. However, after complete surgical resection in patients with node-negative disease, EMVI did not predict local recurrence.

Prognostic significance of partial tumor regression after preoperative chemoradiotherapy for rectal cancer: a meta-analysis. Dis Colon Rectum 2013; 56:1093-101. [PMID: 23929020 DOI: 10.1097/dcr.0b013e318298e36b] [Citation(s) in RCA: 64] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/13/2022]
Abstract
BACKGROUND Complete tumor regression after preoperative chemoradiotherapy for rectal cancer has been associated with better disease-free and overall survival. The survival experience for patients with partial tumor regression is less clear. OBJECTIVE The aim of this meta-analysis was to evaluate the prognostic significance of partial response after preoperative chemotherapy on disease-free survival in rectal cancer patients. DATA SOURCES Relevant studies were identified by a search of MEDLINE and EMBASE databases with no restrictions to October 31, 2012. STUDY SELECTION We included long-course radiotherapy that reported the association between degree of tumor regression and disease-free survival of rectal cancer. INTERVENTIONS Direct, indirect, and graph methods were used to extract HRs. MAIN OUTCOME MEASURES Study-specific HRs on the disease-free survival were pooled using a random-effects model. Eleven articles in total were selected. Analysis was performed first among the 6 studies that separated partial response from the complete response and later among all 11 of the studies. RESULTS Pooled HR was 0.49 (95% CI, 0.28-0.85) for the 6 studies that compared partial response with poor response. It was 0.41 (95% CI, 0.25-0.67) when all 11 of the studies were analyzed together. LIMITATIONS The studies were limited by not being prospective, randomized trials, and the tumor regression grades were not uniform. CONCLUSIONS Partial tumor response is associated with a 50% improvement in disease-free survival and should be considered as a favorable prognostic factor.

Consensus statement on the multidisciplinary management of patients with recurrent and primary rectal cancer beyond total mesorectal excision planes. Br J Surg 2013; 100:1009-14.

Abstract
BACKGROUND The management of primary rectal cancer beyond total mesorectal excision planes (PRC-bTME) and recurrent rectal cancer (RRC) is challenging. There is global variation in standards and no guidelines exist. To achieve cure most patients require extended, multivisceral, exenterative surgery, beyond conventional total mesorectal excision planes. The aim of the Beyond TME Group was to achieve consensus on the definitions and principles of management, and to identify areas of research priority. METHODS Delphi methodology was used to achieve consensus. The Group consisted of invited experts from surgery, radiology, oncology and pathology. The process included two international dedicated discussion conferences, formal feedback, three rounds of editing and two rounds of anonymized web-based voting. Consensus was achieved with more than 80 per cent agreement; less than 80 per cent agreement indicated low consensus. During conferences held in September 2011 and March 2012, open discussion took place on areas in which there is a low level of consensus. RESULTS The final consensus document included 51 voted statements, making recommendations on ten key areas of PRC-bTME and RRC. Consensus agreement was achieved on the recommendations of 49 statements, with 34 achieving consensus in over 95 per cent. The lowest level of consensus obtained was 76 per cent. There was clear identification of the need for referral to a specialist multidisciplinary team for diagnosis, assessment and further management. CONCLUSION The consensus process has provided guidance for the management of patients with PRC-bTME or RRC, taking into account global variations in surgical techniques and technology. It has further identified areas of research priority.

Abstract
Abstract
Background
The aim was to assess the indications for and outcomes of abdominosacral resection for patients with locally advanced primary and recurrent rectal cancer.
Methods
Consecutive patients undergoing abdominosacral resection between January 2006 and December 2011 were identified from a prospectively maintained database. The main endpoints were 3-year local recurrence-free (LRFS) and disease-free (DFS) survival.
Results
Thirty patients underwent abdominosacral resection, 22 for recurrent rectal cancer and eight for locally advanced primary cancer. Sacrectomy was performed at S1/2 in five, S3 in 11 and S4/5 in 14 patients. R0 resection was achieved in 23 patients; all seven positive margins (R1) were in patients with recurrent disease. There were no deaths in hospital or within 30 days. S1/2 sacrectomy was associated with the highest rate of major complications (60 per cent versus 27 and 29 per cent for S3 and S4/5 respectively) and long-term complications (60, 36 and 14 per cent). Overall 3-year LRFS was 66 per cent and 3-year DFS was 55 per cent. Both were significantly better in patients with negative compared with positive margins (LRFS: 87 versus 0 per cent, P < 0·001; DFS: 71 versus 0 per cent, P = 0·033).
Conclusion
Abdominosacral resection was associated with long-term survival in carefully selected patients with advanced rectal cancer. Postoperative complications were common and often multiple. Sacrectomy for locally advanced primary rectal cancer was associated with a low margin-positive rate and should be considered as an acceptable treatment. Margin-positive resection was associated with poor survival outcomes and should be avoided.
