BMC Cancer 2024; 24:593. [PMID: 38750417 PMCID: PMC11095034 DOI: 10.1186/s12885-024-12377-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Accepted: 05/13/2024] [Indexed: 05/19/2024] Open
Abstract
BACKGROUND Total pelvic exenteration (TPE), an en bloc resection is an ultraradical operation for malignancies, and refers to the removal of organs inside the pelvis, including female reproductive organs, lower urological organs and involved parts of the digestive system. The aim of this meta-analysis is to estimate the intra-operative mortality, in-hospital mortality, 30- and 90-day mortality rate and overall mortality rate (MR) following TPE in colorectal, gynecological, urological, and miscellaneous cancers. METHODS This is a systematic review and meta-analysis in which three international databases including Medline through PubMed, Scopus and Web of Science on November 2023 were searched. To screen and select relevant studies, retrieved articles were entered into Endnote software. The required information was extracted from the full text of the retrieved articles by the authors. Effect measures in this study was the intra-operative, in-hospital, and 90-day and overall MR following TPE. All analyzes are performed using Stata software version 16 (Stata Corp, College Station, TX). RESULTS In this systematic review, 1751 primary studies retrieved, of which 98 articles (5343 cases) entered into this systematic review. The overall mortality rate was 30.57% in colorectal cancers, 25.5% in gynecological cancers and 12.42% in Miscellaneous. The highest rate of mortality is related to the overall mortality rate of colorectal cancers. The MR in open surgeries was higher than in minimally invasive surgeries, and also in primary advanced cancers, it was higher than in recurrent cancers. CONCLUSION In conclusion, it can be said that performing TPE in a specialized surgical center with careful patient eligibility evaluation is a viable option for advanced malignancies of the pelvic organs.

Abstract
Simple Summary Worldwide there is still unwarranted variation in peri-operative management and subsequently oncological outcome following pelvic exenteration for locally advanced and recurrent rectal cancer. The major contributing factor seems to be a difference in treatment strategy with many centres aiming for more neoadjuvant treatment and less radical surgery. However, a radical resection with clear operative margins remains the single most important prognostic factor for survival and therefore an aggressive, radical approach is justified for an optimal oncological outcome and remains the gold standard of care. Abstract Pelvic exenteration surgery has become a widely accepted procedure for treatment of locally advanced (LARC) and locally recurrent rectal cancer (LRRC). However, there is still unwarranted variation in peri-operative management and subsequently oncological outcome after this procedure. In this article we will elaborate on the various reasons for the observed differences based on benchmarking results of our own data to the data from the PelvEx collaborative as well as findings from 2 other benchmarking studies. Our main observation was a significant difference in extent of resection between exenteration units, with our unit performing more complete soft tissue exenterations, sacrectomies and extended lateral compartment resections than most other units, resulting in a higher R0 rate and longer overall survival. Secondly, current literature shows there is a tendency to use more neoadjuvant treatment such as re-irradiation and total neoadjuvant treatment and perform less radical surgery. However, peri-operative chemotherapy or radiotherapy should not be a substitute for adequate radical surgery and an R0 resection remains the gold standard. Finally, we describe our experiences with standardizing our surgical approaches to the various compartments and the achieved oncological and functional outcomes.

Abstract
BACKGROUND This study aims to identify prognostic factors and define the best extent of surgery for optimizing treatment of local recurrence (LR) following colorectal cancer (CRC). METHODS An institutional database of consecutive patients who underwent radical resection (R0/R1) of LR following CRC was analyzed prospectively from 2010 to 2021 at one tertiary cancer center. RESULTS In this study, 75 patients were included with LR following CRC and analyzed. Patients were categorized as compartmental resections (CompRe) (n = 47) if all adjacent organs were systematically removed, with or without tumor involvement, or noncompartmental resections (NoCompRe) (n = 28) if only contiguously involved organs were resected. NoCompRe were mainly related to contact between major vessels or bone and the tumor, with only 8/19 (42.1%) resections. Five-year overall survival and locoregional-free survival were 37.5% and 38.8% respectively. Local control was better in the CompRe than the NocompRe group (61.4% vs. 11%; p < 0.01). CompRe (hazard ratio: 2.34 [1.16-4.68]; p = 0.017) and absence of peritoneal metastasis (3.05 [1.03-9.02]; p = 0.044) were the two factors associated with decreased abdominal recurrences in multivariate analysis. CONCLUSION Complete compartmental surgery is safe and improves local control. Optimal LR resection needs to remove all contiguous organs, with or without tumor involvement.

Abstract
PURPOSE To assess pain management in patients post-sacrectomy, focusing on opioid use, and to identify the factors associated with postoperative pain. METHODS Patients who underwent resection of locally recurrent rectal cancer (LRRC) with concomitant sacrectomy at one of two hospitals between 2007 and 2020 were reviewed retrospectively. We examined the use of opioids preoperatively and postoperatively. Patients were classified into high and low sacrectomy groups based on the sacral bone resection level passing through the S3 vertebra. RESULTS Sixty-four patients were enrolled. Opioid use was significantly higher in the high sacrectomy group than in the low sacrectomy group at all times assessed: on postoperative days 7, 14, 30, 90, 180, and 365. Opioid use 3 months after locally recurrent rectal cancer surgery was significantly higher in patients with local re-recurrence of the tumor than in those without re-recurrence (p < 0.05), and the median morphine-equivalent opioid use 3 months postoperatively was significantly higher in the high sacrectomy group (30 vs. 0 mg/day; p < 0.05). CONCLUSIONS Opioid use after concomitant sacrectomy for LRRC was higher in the high sacrectomy group. Prolonged postoperative pain or increasing pain was associated with local recurrence.

Abstract
Context: Chordomas are rare primary tumors of bone characterized by local aggressiveness and poor prognosis. The surgical exeresis plays a critical role for their management. Objective: The aim was to provide an overview of the surgical management of chordomas of the mobile spine and sacrum, describing the most common surgical approaches, the role of surgical margins, the difficulties of en block resection, the outcomes of surgery, the recurrence rate and the use of associated therapies. Methods: We performed a systematic search using the keywords "chordoma" in combination with "surgery", "spine", "sacrum" and "radiotherapy". Results: Fifty-eight studies, describing 1359 patients with diagnosis of chordoma were retrieved. 17 studies were performed on subjects with cervical chordomas and 49 focused on patients with sacrococcygeal chordomas. The remaining studies included patients with chordomas in cranial region and/or mobile spine and/or sacroccygeal region. The recurrence rate ranged from 25% to 60% for cervical chordomas, and from 18% to 89% for sacrococcygeal chordomas. Conclusion: Despite the remarkable advances in the local management of chordoma performed in the last decades, the current results of surgery alone are still unsatisfactory. The radical en bloc excision of tumour is technically demanding, particularly in the cervical spine. Although radical surgery must still be considered the gold standard for the management of chordomas, a multidisciplinary approach is required to improve the local control of the disease in patients who undergo both radical and non-radical surgery. Adjuvant radiation therapy increases the continuous disease-free survival and the local recurrence-free survival. Level of evidence: Systematic review; level III.

Abstract
A randomized phase III trial was initiated in Japan in August 2019 to confirm the superiority of preoperative chemoradiotherapy followed by surgery plus adjuvant chemotherapy compared to the standard treatment, i.e. surgery plus adjuvant chemotherapy, for locally recurrent rectal cancer in local relapse-free survival. In all, 110 patients from 43 Japanese institutions will be recruited over a period of 6 years. Eligible patients would be registered and randomly assigned to each group with an allocation ratio of 1:1. The primary endpoint is local relapse-free survival. The secondary endpoints are overall survival, relapse-free survival, proportion of local relapse, proportion of distant relapse, proportion of patients with pathological R0 resection, response rate of preoperative chemoradiotherapy (preoperative chemoradiotherapy arm), pathological complete response rate (preoperative chemoradiotherapy arm), proportion of patients who completed the protocol treatment, incidence of adverse events (adverse reactions) and quality of life after surgery. This trial has been registered at the Japan Registry of Clinical Trial: jRCTs031190076 [https://jrct.niph.go.jp/latest-detail/jRCTs031190076] and ClinicalTrials.gov: NCT04288999 [https://clinicaltrials.gov/ct2/show/NCT04288999].

Abstract
Abstract
Local recurrence of rectal cancer is defined as any evidence of relapse within the small pelvis after surgical resection of the primary tumor. After removal of a rectal tumor, necrotic cellular debris and viable exfoliated cancer cells are present in the rectal lumen; using saline or povidone-iodine solution, many surgeons perform rectal washout beyond an occlusive clamp to remove these exfoliated malignant cells, which may lead to local recurrence. A meta-analysis showed that intraoperative rectal washout at the surgical anastomosis site can reduce the risk of local recurrence after rectal cancer resection. Therefore, intraluminal lavage is useful to prevent local recurrence. Although intraoperative rectal washing is considered to be important, there is probably room for improvement on this method. We described the idea of a new transanal irrigation and aspiration system for small rectal contents. The aim of this research was to investigate the effect of a new rectal washout system using a chemiluminescent imaging system. We attempted to evaluate and compare the washout efficiency between this new system and the conventional irrigation system using a cylindrical rectum model. Our results implied that, at the same volume of solution, the irrigation–aspiration rectal washout system was more effective than the irrigation washout system. This new rectal washout system was easy to use and allowed a good washout. To the best of our knowledge, this was the first report that evaluated the efficacy of a rectal washout system using quantitative data.

Abstract
BACKGROUND Locally recurrent rectal cancer (LRRC) is a complex problem requiring multidisciplinary consultation and specialized surgical care. Given the paucity of published longer-term survival data, skepticism persists regarding the benefit of major extirpative surgery. We investigated ultra-long-term (~15 years) outcomes following radical resection of LRRC and sought relevant clinicopathologic prognostic variables. METHODS A cohort of 52 consecutive patients who underwent resection of LRRC at our institution between 1997 and 2005 were followed with serial exams and imaging up to the point of death, or 30/06/2019. RESULTS Median follow-up time was 16.5 years (9.9-18.3) for patients who were alive at last follow-up; only one patient was lost to follow-up, at 9.9 years. For the entire cohort of 52 patients, disease-specific survival (DSS) at 5, 10, and 15 years following salvage surgery was 41%, 33%, and 31%, respectively. All patients who had distant metastatic disease at the time of LRRC resection (n = 6) subsequently died of cancer, at a median of 21 months (4-46). In those without distant metastases at time of salvage surgery (n = 46), DSS at 5, 10, and 15 years was 47%, 38%, and 35%, respectively, median 60 months. Negative resection margin (R0) was independently predictive of superior outcomes. In patients with M0 disease who had R0 resection (n = 37), DSS at 5, 10 and 15 years was 58%, 47%, and 44%, respectively, median 73 months. No patient developed re-recurrence after 5.5 years. CONCLUSIONS This study demonstrates exceptionally durable long-term cancer-free survival following salvage surgery for LRRC, indicating that cure is possible.

Abstract
PURPOSE Pelvic exenteration (PE) for locally advanced or recurrent colorectal cancer is often used to secure negative resection margins. The aim of this study was to evaluate the feasibility of laparoscopic PE. MATERIALS AND METHODS The clinical records of 24 patients (9, open; 15, laparoscopic) who underwent total or posterior PE for locally advanced or recurrent colorectal cancer between July 2012 and April 2016 at Osaka National Hospital were retrospectively reviewed. Operative factors were compared between the 2 groups. RESULTS The R0 resection rate was 100% in the laparoscopic group and 89% in the open group. The operative time and the incidence of postoperative complications were not significantly different between the 2 groups. The laparoscopic group showed less intraoperative blood loss (P=0.019), a lower C-reactive protein elevation on postoperative day 7 (P=0.025), and a shorter postoperative hospital stay (P=0.0009). CONCLUSIONS Laparoscopic PE is a safe and feasible procedure to reduce postoperative stress.

[PMID: 32207572 PMCID: PMC7093787 DOI: 10.1002/bjs5.50234] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2019] [Revised: 09/22/2019] [Accepted: 09/30/2019] [Indexed: 12/13/2022] Open
Abstract
Background This study investigated the results of transanal total mesorectal excision (TaTME) combined with laparoscopy for locally advanced mid–low rectal cancer. Methods Patients with mid–low locally advanced rectal cancer (T3 category or above and/or N+) who underwent rectal resection with TaTME technique were enrolled prospectively. Patients who had distant metastasis, multiple malignancies, intestinal obstruction or perforation, or a clinical complete response to chemoradiotherapy were excluded. Postoperative results, including morbidity, circumferential resection margin (CRM) assessment, short‐term survival and functional outcomes, were analysed. Results Thirty‐eight patients, with 25 mid and 13 low rectal tumours, who had elective resection by TaTME from March 2015 to September 2018 were included. There were 25 men and 13 women. Mean(s.d.) age was 58·2(16·4) years and mean(s.d.) BMI was 24·2(2·5) kg/m2. Tumours were 3–9 cm from the anal verge. Mean(s.d.) duration of surgery was 210(42) min. All patients had hand‐sewn anastomoses and protective ileostomies. There were no conversions, abdominal perineal resections or postoperative deaths. Four patients had a complication, including three presacral abscesses, all managed by transanastomotic drainage. At 3 months after ileostomy closure, all patients had perfect continence. Apart from a greater tumour diameter in patients with low rectal cancers (6·0 cm versus 4·6 cm in those with mid rectal tumours; P = 0·035), clinical features were similar in the two groups. CRM positivity was greater for low than for mid rectal tumours (3 of 13 versus 0 of 25 respectively; P = 0·034), and more patients with a low tumour had TME grade 2 (4 of 13 versus 1 of 25; P = 0·038). There was no difference in oncological outcomes at 17 months. Conclusion Although this study cohort was small, special attention should be paid to bulky low rectal tumours to reduce the rate of CRM positivity.

Abstract
BACKGROUND There are few data on lymphatic spread concomitant to local recurrence (LR) of colorectal cancer (CRC). The objectives of this study were to determine variables associated with lymphatic spread, to analyze the distribution of LN+, and understand the underlying mechanisms. METHODS A total of 76 patients underwent resection of LR of CRC between January 2007 and December 2018 at Institut cancérologique de l'Ouest and were retrospectively reviewed. RESULTS Twenty-five (32.9%) patients had lymph node (LN) involvement with LR. Lymphatics from the mesocolon-rectum and aorto-iliac compartments were involved in 21%, 20.3% and 18.1%, 20.3% for pelvic and retroperitoneal LRs, respectively. In multivariate analysis, the only predictive factor for LN invasion (LN+) was a primary positive LN status (odds ratio, 5.3; P = .007). Despite a trend toward a worse median overall survival in the LN+ group, the difference was not significant in comparison with the LN- group (46 vs. 57 months; P = 0.31) or with the LN- plus LN not assessed groups (46 months vs not reached; P = .07). CONCLUSIONS LN invasion with LR from CRC is a frequent occurrence without significant impact on survival. The only predictive factor is a primary positive nodal status.

Abstract
OBJECTIVE To evaluate outcomes and toxicity profiles after re-irradiation in patients with pelvic recurrence of anorectal cancer. METHODS 25 anorectal cancer patients who received re-irradiation for pelvic recurrence between 2005 and 2015 were included. For initial treatment, all patients underwent surgical resection and preoperative or postoperative radiotherapy. RESULTS The median follow-up duration was 21.5 months (range, 2.9-84.4). After a median of 43.3 months (range, 11.7-218.5), patients received re-irradiation with a median dose of 45 Gy (range, 36-60). The equivalent dose in 2 Gy fractions (EQD2) of re-irradiation-calculated using α/β = 10 Gy-ranged from 34.5 to 84.0 Gy (median, 46.4). Surgical resection was performed for 11 patients, and 14 patients received concurrent chemotherapy with re-irradiation. The 3-year local progression-free survival was 29.7%. The 3-year overall survival was 49.7%. Concurrent chemotherapy with re-irradiation and re-irradiation doses >50 Gy EQD2α/β=10 were significant prognostic factors for local progression free survival and overall survival according to multivariate analysis. 90% (9 of 10) of patients with symptoms had improvement after re-irradiation. Among 23 patients available for evaluation of late toxicity, 12 developed late toxicities. There were no Grade 4 late toxicities, and 6 patients had Grade 3 late toxicities (small bowel obstruction, bowel perforation and fistula). CONCLUSION Re-irradiation for pelvic recurrence of anorectal cancer improved symptoms of patients but the rate of late toxicity was high. Further investigation for patient selection is required. ADVANCES IN KNOWLEDGE Re-irradiation could be considered as a possible option for pelvic recurrence of anorectal cancer in selected patients.

Abstract
INTRODUCTION R0 resection is achieved by high sacrectomy for local recurrence of colorectal cancer, but significant rates of perioperative complications and long-term patient morbidity are associated with this procedure. In this report, we outline our unique experience of using an expandable cage for vertebral body reconstruction following S1 sacrectomy in a 66-year-old patient with re-recurrent rectal cancer. We aim to highlight several key steps, with a view to improving postoperative outcomes. TECHNIQUE A midline laparotomy was performed with the patient in supine Lloyd-Davies position, demonstrating recurrence of tumor at the S1 vertebral body. Subtotal vertebral body excision of S1 with sparing of the posterior wall and ventral foramina was completed by using an ultrasonic bone aspirator. Reconstruction was performed using an expandable corpectomy spacer system. The system was assembled and expanded in situ to optimally bridge the corpectomy. The device was secured into the L5 and S2 vertebrae by means of angled end plate screws superiorly and inferiorly. Bone grafts were positioned adjacent to the implant after this. RESULTS Total operating time was 266 minutes with 350 mL of intraoperative blood loss. There were no immediate postoperative complications. The patient did not report any back pain at the time of discharge, and no neurological deficit was reported or identified. Postoperative CT scan showed excellent vertebral alignment and preservation of S1 height. CONCLUSION We conclude that high sacrectomy with an expandable metal cage is feasible in the context of re-recurrent rectal cancer when consideration is given to the method of osteotomy and vertebral body replacement.

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.

Extended pelvic resections for the treatment of locally advanced and recurrent anal canal and colorectal cancer: technical aspects and morbimortality predictors aftet 24 consecutive cases. Rev Col Bras Cir 2017; 43:93-101. [PMID: 27275590 DOI: 10.1590/0100-69912016002005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2015] [Accepted: 03/07/2016] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE to evaluate the profile of morbidity and mortality and its predictors related to extensive pelvic resections, including pelvic exenteration, to optimize the selection of patients and achieve better surgical results. METHODS we performed 24 major resections for anorectal pelvic malignancy from 2008 to 2015 in the Instituto do Câncer do Ceará. The factors analyzed included age, weight loss, resected organs, total versus posterior exenteration, angiolymphatic and perineural invasion, lymph node metastasis and overall and disease-free survival. RESULTS the median age was 57 years and the mean follow-up was ten months. Overall morbidity was 45.8%, with five (20.8%) serious complications. There were no deaths in the first 30 postoperative days. The median overall survival was 39.5 months, and disease-free survival, 30.7 months. Concomitant resection of the bladder was an isolated prognostic factor for higher risk of complications (87.5% vs. 26.7%, p = 0.009). Angiolymphatic invasion and lymph node metastasis did not reach significance with respect to disease-free survival. CONCLUSION treatment of advanced anorectal tumors is challenging, often requiring combined resections, such as cystectomy and sacrectomy, and complex reconstructions. The magnitude of the operation still carries a high morbidity rate, but is a procedure considered safe and feasible, with a low mortality and adequate locoregional tumor control when performed in referral centers. OBJETIVOS avaliar o perfil de morbimortalidade e seus fatores preditivos relacionados às ressecções pélvicas extensas, incluindo a exenteração pélvica, com o intuito de otimizar a seleção dos pacientes e obtenção de melhores resultados cirúrgicos. MÉTODOS foram realizadas 24 grandes ressecções pélvicas por neoplasia maligna anorretal de 2008 a 2015 no Instituto do Câncer do Ceará. Os fatores analisados incluíram idade, perda de peso, órgão ressecados, exenteração total versus posterior, invasão angiolinfática e perineural, metástase linfonodal e sobrevida global e livre de doença. RESULTADOS a mediana de idade foi 57 anos e o tempo médio de seguimento foi dez meses. A morbidade global foi 45,8%, com cinco (20,8%) complicações graves. Não houve óbito nos primeiros 30 dias de pós-operatório. A sobrevida global média foi 39,5 meses e a sobrevida livre de doença foi 30,7 meses. A ressecção concomitante da bexiga foi fator prognóstico isolado com maior risco para complicações (87,5% vs. 26,7%, p=0.009). Invasão angiolinfática e metástase linfonodal não alcançaram significância com relação à sobrevida livre de doença. CONCLUSÃO o tratamento dos tumores anorretais avançados é desafiador, necessitando frequentemente de ressecções combinadas, como a cistectomia e sacrectomia, além de reconstruções complexas. A magnitude da cirurgia ainda carrega uma elevada taxa de morbidade, porém é um procedimento considerado seguro e factível, com uma baixa mortalidade e adequado controle locorregional tumoral quando realizado em centros de referência.

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
AIM To critically appraise short-term outcomes in patients treated in a new Pelvic Exenteration (PE) Unit.
METHODS This retrospective observational study was conducted by analysing prospectively collected data for the first 25 patients (16 males, 9 females) who underwent PE for advanced pelvic tumours in our PE Unit between January 2012 and October 2016. Data evaluated included age, co-morbidities, American Society of Anesthesiologists (ASA) score, Eastern Cooperative Oncology Group (ECOG) status, preoperative adjuvant treatment, intra-operative blood loss, procedural duration, perioperative adverse event, lengths of intensive care unit (ICU) stay and hospital stay, and oncological outcome. Quantitative data were summarized as percentage or median and range, and statistically assessed by the χ2 test or Fisher’s exact test, as applicable.
RESULTS All 25 patients received comprehensive preoperative assessment via our dedicated multidisciplinary team approach. Long-course neoadjuvant chemoradiotherapy was provided, if indicated. The median age of the patients was 61.9-year-old. The median ASA and ECOG scores were 2 and 0, respectively. The indications for PE were locally invasive rectal adenocarcinoma (n = 13), advanced colonic adenocarcinoma (n = 5), recurrent cervical carcinoma (n = 3) and malignant sacral chordoma (n = 3). The procedures comprised 10 total PEs, 4 anterior PEs, 7 posterior PEs and 4 isolated lateral PEs. The median follow-up period was 17.6 mo. The median operative time was 11.5 h. The median volume of blood loss was 3306 mL, and the median volume of red cell transfusion was 1475 mL. The median lengths of ICU stay and of hospital stay were 1 d and 21 d, respectively. There was no case of mortality related to surgery. There were a total of 20 surgical morbidities, which occurred in 12 patients. The majority of the complications were grade 2 Clavien-Dindo. Only 2 patients experienced grade 3 Clavien-Dindo complications, and both required procedural interventions. One patient experienced grade 4a Clavien-Dindo complication, requiring temporary renal dialysis without long-term disability. The R0 resection rate was 64%. There were 7 post-exenteration recurrences during the follow-up period. No statistically significant relationship was found among histological origin of tumour, microscopic resection margin status and postoperative recurrence (P = 0.67). Four patients died from sequelae of recurrent disease during follow-up.
CONCLUSION By utilizing modern assessment and surgical techniques, our PE Unit can manage complex pelvic cancers with acceptable morbidities, zero-rate mortality and equivalent oncologic outcomes.

Abstract
Purpose of review Three-dimensional conformal radiation therapy (3DCRT) has been the standard technique in the treatment of rectal cancer. The use of new radiation treatment technologies such as intensity-modulated radiation therapy (IMRT), proton therapy (PT), stereotactic body radiation therapy (SBRT) and brachytherapy (BT) has been increasing over the past 10 years. This review will highlight the advantages and drawbacks of these techniques. Recent findings IMRT, PT, SBRT and BT achieve a higher target coverage conformity, a higher organ at risk sparing and enable dose escalation compared to 3DCRT. Some studies suggested a reduction in gastrointestinal and hematologic toxicities and an increase in the complete pathologic response rate; however, the clinical benefit of these techniques remains controversial. Summary The results of these new techniques seem encouraging despite conclusive data. Further trials are required to establish their role in rectal cancer.

Abstract
BACKGROUND The management of recurrent rectal cancer is challenging. At the present time, pelvic exenteration with en bloc sacrectomy offers the only hope of a lasting cure. OBJECTIVE The purpose of this study was to evaluate clinical outcome measures and complication rates following sacrectomy for recurrent rectal cancer. DATA SOURCES A search was conducted on Pub Med for English language articles relevant to sacrectomy for recurrent rectal cancer with no time limitations. STUDY SELECTION Studies reported sacrectomy with survival data for recurrent rectal adenocarcinoma. MAIN OUTCOME MEASURE Disease-free survival following sacrectomy for recurrent rectal cancer was the main outcome measured. RESULTS A total of 220 patients with recurrent rectal cancer were included from 7 studies, of which 160 were men and 60 were women. Overall median operative time was 717 (570-992) minutes and blood loss was 3.7 (1.7-6.2) L. An R0 (>1-mm resection margin) resection was achieved in 78% of patients. Disease-free survival associated with R0 resection was 55% at a median follow-up period of 33 (17-60) months; however, none of the patients with R1 (<1-mm resection margin) survived this period. Postoperative complication rates and median length of stay were found to decrease with more distal sacral transection levels. In contrast, R1 resection rates increased with more distal transection. LIMITATION The studies assessed by this review were retrospective case series and thus are subject to significant bias. CONCLUSION Sacrectomy performed for patients with recurrent rectal cancer is associated with significant postoperative morbidity. Morbidity and postoperative length of stay increase with the level of sacral transection. Nevertheless, approximately half of patients eligible for rectal excision with en bloc sacrectomy may benefit from disease-free survival for up to 33 months, with R0 resection predicting disease-free survival in the medium term.

Abstract
AIM To investigate feasibility and outcome of abdominal-sacral resection for treatment of locally recurrent rectal adenocarcinoma.
METHODS A population of patients who underwent an abdominal-sacral resection for posterior recurrent adenocarcinoma of the rectum at the National Cancer Institute of Milano, between 2005 and 2013, is considered. Retrospectively collected data includes patient characteristics, treatment and pathology details regarding the primary and the recurrent rectal tumor surgical resection. A clinical and instrumental follow-up was performed. Surgical and oncological outcome were investigated. Furthermore an analytical review of literature was conducted in order to compare our case series with other reported experiences.
RESULTS At the time of abdomino-sacral resection, the mean age of patients was 55 (range, 38-64). The median operating time was 380 min (range, 270-480). Sacral resection was performed at S2/S3 level in 3 patients, S3/S4 in 3 patients and S4/S5 in 4 patients. The median operating time was 380 ± 58 min. Mean intraoperative blood loss was 1750 mL (range, 200-680). The median hospital stay was 22 d. Overall morbidity was 80%, mainly type II complication according to the Clavien-Dindo classification. Microscopically negative margins (R0) is obtained in all patients. Overall 5-year survival after first surgical procedure is 60%, with a median survival from the first surgery of 88 ± 56 mo. The most common site of re-recurrence was intrapelvic.
CONCLUSION Sacral resection represents a feasible approach to posterior rectal cancer recurrence without evidence of distant spreading. An accurate staging is essential for planning the best therapy.

Abstract
Local recurrence of rectal cancer is difficult to treat, may cause severe and disabling symptoms, and usually has a fatal outcome. The aim of this study was to document the clinical nature of locally recurrent rectal cancer and to determine the effect of surgical resection on long-term survival.A retrospective review was conducted of the prospectively collected medical records of 2485 patients with primary rectal adenocarcinoma who underwent radical resection between September 1994 and December 2008.In total, 147 (5.9%) patients exhibited local recurrence. The most common type of local recurrence was lateral recurrence, whereas anastomotic recurrence was the most common type in patients without preoperative concurrent chemoradiotherapy (CCRT). Tumor location with respect to the anal verge significantly affected the local recurrence rate (P < 0.001), whereas preoperative CCRT did not affect the local recurrence rate (P = 0.433). Predictive factors for surgical resection of recurrent rectal cancer included less advanced tumor stage (P = 0.017, RR = 3.840, 95% CI = 1.271-11.597), axial recurrence (P < 0.001, RR = 5.772, 95% CI = 2.281-14.609), and isolated local recurrence (P = 0.006, RR = 8.679, 95% CI = 1.846-40.815). Overall survival after diagnosis of local recurrence was negatively influenced by advanced pathologic tumor stage (P = 0.040, RR = 1.867, 95% CI = 1.028-3.389), positive CRM (P = 0.001, RR = 12.939, 95% CI = 2.906-57.604), combined distant metastases (P = 0.001, RR = 2.086, 95% CI = 1.352-3.218), and nonsurgical resection of recurrent tumor (P < 0.001, RR = 4.865, 95% CI = 2.586-9.153).In conclusion, the clinical outcomes of local recurrence after curative resection of rectal cancer are diverse. Surgical resection of locally recurrent rectal cancer should be considered as an initial treatment, especially in patients with less advanced tumors and axial recurrence.

Abstract
BACKGROUND Advanced pelvic cancers involving the lateral pelvic compartment, and particularly the iliac vasculature, are difficult to manage. Common or external iliac vessel involvement has traditionally been considered a contraindication for curative surgery. OBJECTIVE The purpose of this study was to investigate pathological and surgical outcomes, particularly postoperative morbidity of pelvic exenteration with en bloc major iliac vascular excision and reconstruction. DESIGN This study was a case series. SETTINGS The study was conducted at a quaternary referral center for pelvic exenteration in Sydney. PATIENTS Patients included those undergoing en bloc iliac vessel excision as part of their pelvic exenteration for a locally advanced pelvic malignancy. MAIN OUTCOME MEASURES Over the study period, 336 patients underwent pelvic exenteration. Twenty-one patients (6.3%) underwent en bloc vascular excision of 29 vessels for tumor involvement. Twenty-four vessels required reconstruction. The primary outcomes were postoperative complications and pathologic outcomes. Survival rates were estimated using the Kaplan-Meier technique. RESULTS Operating time for patients who underwent vascular excision and reconstruction was longer, but this did not reach significance (631 vs 531 minutes; p = 0.052). Mean blood loss was significantly higher in the vascular excision and reconstruction group (6.8 vs 3.4 L; p < 0.001). Patients who required en bloc vascular excision were less likely to have R0 margins compared with patients who did not (38% vs 78%; p < 0.001). There was no intraoperative or 30-day mortality. Overall graft patency and limb loss at 1 year were 96% and 0%. A total of 52% of patients had at least 1 vascular related complication. Median overall and disease-free survival times were 34 and 26 months. LIMITATIONS This study is limited by a relatively small number of heterogeneous patients. CONCLUSIONS En bloc vascular resection and reconstruction for contiguous tumor involvement is feasible and safe in selected patients. Advanced pelvic tumors involving iliac vessels should not be precluded from curative surgery in specialized institutions.

Abstract
BACKGROUND This Sawbones and cadaver study was performed to assess the accuracy and reproducibility of pelvic bone cuts made with use of a novel navigation system with a navigated osteotome and oscillating saw. METHODS Using a novel navigation system and a three-dimensional planning tool, we navigated pelvic bone cuts that were representative of typical cuts made in pelvic tumor resections. The system includes a prototype mobile C-arm for intraoperative cone-beam computed tomography, real-time optical tracking (Polaris), and three-dimensional visualization software. Three-dimensional virtual radiographs were utilized in addition to triplanar (axial, sagittal, and coronal) navigation. In part one of the study, we navigated twenty-four sacral bone cuts in Sawbones models and validated our results in sixteen similar cuts in cadavers. In part two, we developed three Sawbones models of pelvic tumors based on actual patient scenarios and compared three navigated resections with three non-navigated resections for each tumor model. Part three assessed the accuracy of the system with multiple users. RESULTS There were ninety navigated cuts in Sawbones that were compared with fifty-four non-navigated cuts. In the navigated Sawbones cuts, the mean entry and exit cuts were 1.4 ± 1 mm and 1.9 ± 1.2 mm from the planned cuts, respectively. In comparison, the entry and exit cuts in Sawbones that were not navigated were 2.8 ± 4.9 mm and 3.5 ± 4.6 mm away from the planned osteotomy site. The navigated cuts were significantly more accurate (p ≤ 0.01). In the cadaver study, navigated entry and exit cuts were 1.5 ± 0.9 mm and 2.1 ± 1.5 mm from the planned cuts. The variation among three different users was 1 mm on both the entry and exit cuts. CONCLUSIONS Navigation to guide pelvic bone cuts is accurate and feasible. Three-dimensional radiographs should be used for improved accuracy. Navigated cuts were significantly more accurate than non-navigated cuts were. A margin of 5 mm between the target tumor volume and the planned cut plane would result in a negative margin resection in more than 95% of the cuts. CLINICAL RELEVANCE The accuracy of pelvic bone tumor resections and pelvic osteotomies can be improved with navigation to within 5 mm of the planned cut.

Abstract
BACKGROUND In the current era of total mesorectal excision, local relapse remains a main cause of recurrence. Although standard treatment for locally recurrent rectal cancer (LRRC) has not been established, R0 resection represents the only potentially curative treatment. However, extended surgery accompanying bony pelvic resection is technically demanding and is still challenging. METHODS Studied were 35 patients with LRRC who underwent combined resection of bony pelvis between August 2006 and October 2013. Safety and prognostic factors for survival were analyzed. Median follow-up was 33 months. RESULTS Sacrectomy was performed in 32 patients and 3 patients underwent combined resection of the pubis and ischium. The dominant operative procedure was total pelvic exenteration in 30 (86%) patients. R0 resection was achieved in 27 (77%) patients. No patients died. Pelvic sepsis was the most frequent complication (40%). Recurrence developed in 20 (57%), with the lung the most frequent site (10 patients). Three-year local relapse-free survival (LRFS) and disease-free survival (DFS) were 72.1% and 32.7%, respectively. On multivariate analysis, R1 resection was the only independent risk factor for local recurrence (p = 0.010), and concomitant liver metastasis and initial non sphincter-preserving surgery were independent predictors of worse DFS (p = 0.008 and p = 0.042, respectively). CONCLUSIONS Aggressive surgical treatment combined with bony resection for carefully selected patients with LRRC was safe with a high rate of R0 resection and favorable LRFS. However, DFS was not satisfactory even after R0 resection and the main cause was lung metastasis. Preventing distant recurrence might be a key to improve survival.

Abstract
BACKGROUND Surgery is the only curative treatment in patients with locally recurrent rectal cancer (LRRC). The aim of this study was to evaluate the outcome and the prognostic factors of tumour-free resection margin (R0) and overall survival (OS) in LRRC. METHODS Consecutive LRRC patients observed between 1987 and 2005 in three Italian university hospitals were evaluated. Survival curves were estimated using the Kaplan-Meier method and compared with the log-rank test. In order to identify factors associated with both R0 resection and OS, a logistic regression analysis was performed in patients who underwent surgery with curative intent. RESULTS Out of 150 patients with LRRC, 107 underwent surgery, but since 7 were found to have unresectable disease only 100 underwent surgical resection. Of them, 51 underwent radical and 49 extended resection. Sixty of the 107 patients underwent multimodality treatment. In 61 patients, R0 resection was achieved. Median OS after surgery was 43.4 months. In patients, who had surgery with curative intent, independent variables associated with R0 resection were: surgery for the primary tumour performed in other hospitals (p = 0.042) extended resection (p = 0.025) and use of positron emission tomography (PET) as a staging modality (p = 0.03). Independent variables associated with OS were: post-operative radiotherapy (p = 0.004), stage of the primary tumour (p = 0.004), R0 resection (p = 0.00001), and use of PET (0.02). CONCLUSIONS Resection for LRRC results in improved survival. Other than the well-known prognostic factors R0 resection and OS, PET scan has an independent impact both on OS and R0 resection. It should therefore be included in routine clinical practice when staging LRRC.

Abstract
BACKGROUND Recurrent and advanced primary pelvic cancers present a complex clinical issue requiring multidisciplinary care and radical extended surgery. Sacral resection is necessary for tumors that invade posteriorly but is associated with increased morbidity and mortality. OBJECTIVE This study aimed to analyze the morbidity and survival associated with pelvic exenteration involving sacrectomy for advanced pelvic cancers at a single institution. DESIGN This study used patient demographics, operative and pathologic reports, and prospective survival data to determine factors affecting patient outcomes. SETTINGS Data were collected for patients who had operations between July 1998 and April 2012 at Royal Prince Alfred Hospital. PATIENTS One hundred patients underwent pelvic exenteration with a sacrectomy for advanced pelvic cancers. Sacrectomy was performed for 18 primary and 61 recurrent rectal cancers, 17 anal cancers, and 4 other cancers. MAIN OUTCOME MEASURES This study looked at postoperative major and minor morbidity rates, as well as disease-free and overall survival rates after sacral resection. It compared the outcomes of high sacrectomy (at or above S2) versus low sacrectomy. RESULTS Clear margins were achieved in 72 of 100 patients. The overall complication rate was 74% (43% major and 67% minor) with no 30-day or in-hospital mortality. Estimated overall and disease-free survival rates after curative resection were 38% and 30% at 5 years. Involved margins (p = 0.006), lymph node involvement (p = 0.008), and anterior organ invasion (p = 0.008) had a negative impact on patient survival. High sacrectomy increased the incidence of neurologic deficit postoperatively (p = 0.04) but did not alter the rate of R0 resection or patient survival. LIMITATIONS Retrospective data were required to analyze patient morbidity, as well as operative and pathologic factors. CONCLUSIONS This series supports sacral resection for curative surgery in advanced pelvic cancers, achieving excellent R0 and long-term survival rates. Cortical bone invasion and high sacrectomy were not contraindications to surgery and had acceptable outcomes.

Abstract
BACKGROUND Intraoperative radiotherapy (IORT) has been given for primary and locally recurrent rectal cancer for 30 years. Still, its effect is not clear. MATERIAL AND METHODS PubMed and EMBASE search for papers after 1989 on surgical treatment and external beam radiotherapy (EBRT) for primary advanced and locally recurrent rectal cancer, with and without IORT. From each center the most recent paper was generally selected. Survival and local recurrence at five years was tabulated for the total groups and separate R-stages. Also, the technique for IORT, use of EBRT and chemotherapy as well as surgical approach was registered. RESULTS In primary cancer 18 papers from 14 centers were tabulated, including one randomized and five internally comparing studies, as well as seven studies without IORT. In locally recurrent cancer 18 papers from 13 centers were tabulated, including four internally comparing studies and also five without IORT. Overall survival (OS) and local recurrence rate (LRR) were higher for primary cancer compared to recurrent cancer. Patients with R0 resections had better outcome than patients with R1 or R2 resections. For primary cancer OS and LR rate of the total groups and R0 stages was not influenced by IORT. An effect on R1/R2 stages cannot be excluded. The only randomized study (primary cancer) did not show any effect of IORT. CONCLUSION IORT does not convincingly improve OS and LR rate for primary and locally recurrent rectal cancer. If there is an effect of IORT, it is small and cannot be shown outside randomized studies analyzing the separate R stages.

Abstract
PURPOSE To analyze prognostic factors and long-term outcomes in patients with locally recurrent pelvic cancer (LRPC) treated with a multidisciplinary approach. METHODS AND MATERIALS From January 1995 to December 2011, 81 patients [rectal (47 %); gynecologic (39 %); retroperitoneal sarcoma (14 %)] underwent extended surgery [multiorgan (58 %), bone (35 %), vascular (9 %), soft tissue (63 %)] and intraoperative electron beam radiation therapy (IOERT) to treat recurrent tumors in the pelvic region. Thirty-five patients (43 %) received external beam radiotherapy (EBRT). Survival was estimated using the Kaplan-Meier method, and risk factors were identified using univariate and multivariate analysis. RESULTS Median follow-up was 39 months (6-189 months); the 1- 3- and 5-year rates of locoregional control (LRC) were 83, 53, and 41 %, respectively. Univariate Cox proportional hazard analysis revealed worse LRC in patients who did not receive integrated EBRT as rescue treatment of pelvic recurrence (p = 0.003) or underwent non-radical resection (p = 0.01). In the multivariate analysis EBRT, non-radical resection, and tumor fragmentation retained significance (p = 0.002, p = 0.004, and p = 0.05, respectively). CONCLUSIONS Radical resection, absence of tumor fragmentation and addition of EBRT for rescue are associated with improved LRC in patients with LRPC. Our results suggest that this group can benefit from EBRT combined with extended surgical resection and IOERT.

Abstract
STUDY DESIGN A review of prospectively collected data on a consecutive series of patients undergoing single-stage anterior high sacrectomy for locally recurrent rectal carcinoma (LRRC). OBJECTIVE To determine the clinical outcome of patients who underwent anterior high sacrectomy for LRRC. SUMMARY OF BACKGROUND DATA High sacrectomy for oncological resection remains technically challenging. Surgery has the potential to achieve cure in carefully selected patients. Complete (R0) tumor excision in LRRC may require sacrectomy. High sacral resections (S3 and above) typically require a combined anterior/supine and posterior/prone procedure. We investigated our experience performing single-stage anterior high sacrectomy for LRRC. METHODS A consecutive series of patients with LRRC without systemic metastases who underwent resection with curative intent requiring high sacrectomy were identified. A review of a prospectively maintained colorectal and spine cancer database data was performed. An oblique dome high sacral osteotomy was performed during a single-stage anterior procedure. Outcome measures included surgical resection margin status, hospital length of stay, postoperative complications, physical functioning status, and overall survival. RESULTS Nineteen consecutive patients were treated between 2002 and 2011. High sacrectomy was performed at sacral level S1-S2 in 4 patients, S2-S3 in 9 patients, and through S3 in 6 patients. An R0 resection margin was achieved histologically in all 19 cases. There was 1 early (<30 d) postoperative death (1/19, 5%). At median follow-up of 38 months, 13 patients had no evidence of residual disease, 1 was alive with disease, and 4 had died of disease. Morbidities occurred in 15 of the 19 patients (79%). CONCLUSION Although high sacrectomy may require a combined anterior and posterior surgical approach, our series demonstrates the feasibility of performing single-stage anterior high sacrectomy in LRRC, with acceptable risks and outcomes compared with the literature. The procedure described by us for LRRC lessens the need for a simultaneous or staged prone posterior resection, with favorable R0 tumor resections, patient survival, and clinical outcomes.

Abstract
OBJECTIVES To describe the experience of sacrectomy with extended radical resection in the treatment of locally recurrent rectal cancer. BACKGROUND Resections of the bony pelvis, especially the sacrum, are becoming more common as part of extended radical exenterations for patients with recurrent rectal cancer. However, sacrectomy has been shown to carry a significant decrease in survival. Morbidity rates have been associated with the level of the sacrectomy (ie, >S3 junction). METHODS An analysis was conducted using prospective data from patients with recurrent rectal cancer who underwent pelvic exenteration involving sacrectomy from July 1998 until June 2011. The impact of the proximal level of sacrectomy [low (≤S3) vs high (≥S2-S3 disc)] was compared. RESULTS Of 240 exenteration patients, 79 underwent sacrectomy, with 49 for recurrent rectal cancer. An R0 margin was achieved in 36 (74%) patients. Achievement of clear operative margins (R0) conferred a large and significant benefit for disease-free survival compared with R1 and R2 resections (median 45 months vs 19 and 8 months, respectively; P = 0.045). Complications were reported in 40 (82%) patients, with major and minor complications in 19 (39%) and 38 (78%) patients, respectively. The proximal level of the sacrectomy (high vs low) did not significantly impair the ability to achieve a clear margin and was not associated with an increase in major or minor complications. CONCLUSIONS This large, single-center series has demonstrated that extended pelvic exenteration involving sacrectomy has excellent R0 margins and survival rates for recurrent rectal cancer. A high sacrectomy has comparable results with a more distal abdominosacral resection.

Abstract
BACKGROUND Pelvic exenteration is highly radical surgery offering the only potential cure for locally advanced pelvic cancer. This study compared quality of life and other relevant patient-reported outcomes over 12 months for patients who did and those who did not undergo pelvic exenteration. METHODS Consecutive patients referred for consideration of pelvic exenteration completed clinical and patient-reported outcome assessments at baseline, hospital discharge (exenteration patients only), and 1, 3, 6, 9 and 12 months. Outcomes included cancer-specific quality of life (Functional Assessment of Cancer Therapy - Colorectal; FACT-C), physical and mental health status (Short Form 36 version 2), psychological distress (Distress Thermometer), and pain (study-specific composite) scores. Linear mixed modelling compared trajectories between exenteration and no-exenteration groups. RESULTS Among 182 patients, 148 (81.3 per cent) proceeded to exenteration. There were no baseline differences between the two groups. Among patients who had exenteration, the mean FACT-C score at baseline of 93.0 had reduced by 14·4 points at hospital discharge, but increased to 86·7 at 1 month after surgery and continued to improve, returning to baseline by 9 months. For patients in the no-exenteration group, FACT-C scores decreased between baseline and 1 month, increased slowly to 6 months and then began to decline at 9 months. There were few statistically or clinically significant differences in any patient-reported outcomes between the groups. CONCLUSION Quality of life and related patient-reported outcomes improve rapidly after pelvic exenteration surgery. For 9 months after surgery, these outcomes are comparable with those of similar do patients who do not have surgery; thereafter, there is a decline in patients who do not have exenteration. Pelvic exenteration can be performed with acceptable quality of life and patient-reported outcomes.

Systematic review and meta-analysis of published trials comparing the effectiveness of transanal endoscopic microsurgery and radical resection in the management of early rectal cancer. Colorectal Dis 2014; 16:2-14. [PMID: 24330432 DOI: 10.1111/codi.12474] [Citation(s) in RCA: 57] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2013] [Accepted: 07/16/2013] [Indexed: 12/12/2022]
Abstract
AIM A systematic analysis was conducted of trials comparing the effectiveness of transanal endoscopic microsurgery (TEMS) with radical resection (RR) for T1 and T2 rectal cancer. METHOD An electronic search was carried out of trials reporting the effectiveness of TEMS and RR in the treatment of T1 and T2 rectal cancers. RESULTS Ten trials including 942 patients were retrieved. There was a trend toward a higher risk of local recurrence (odds ratio 2.78; 95% confidence interval 1.42, 5.44; z = 2.97; P < 0.003) and overall recurrence (P < 0.01) following TEMS compared with RR. The risk of distant recurrence, overall survival (odds ratio 0.90; 95% confidence interval 0.49, 1.66; z = 0.33; P = 0.74) and mortality was similar. TEMS was associated with a shorter operation time and hospital stay and a reduced risk of postoperative complications (P < 0.0001). The included studies, however, were significantly diverse in stage and grade of rectal cancer and the use of neoadjuvant chemoradiotherapy. CONCLUSION Transanal endoscopic microsurgery appears to have clinically measurable advantages in patients with early rectal cancer. The studies included in this review do not allow firm conclusions as to whether TEMS is superior to RR in the management of early rectal cancer. Larger, better designed and executed prospective studies are needed to answer this question.

Abstract
BACKGROUND The widespread use of neoadjuvant radiotherapy (nRTx) followed by total mesorectal excision (TME) introduced the problem of treating locally recurrent rectal cancer (LRRC) after nRTx and TME. Few data exist on the outcome of the surgical treatment of this type of LRRC and the influence of nRTx for the primary tumor on the outcome is unclear. METHODS All patients receiving multimodality treatment (including intraoperative radiotherapy) for LRRC in our center between 1996 and 2012 were analyzed retrospectively. The outcome of patients with nonmetastasized resectable LRRC who received nRTx and TME for the primary tumor was compared to the outcome of patients who did not receive nRTx for the primary tumor. RESULTS During this period, 139 patients underwent surgery for LRRC; 93 of these patients underwent curative surgery for LRRC after TME for the primary tumor. Sixty-five patients did not receive nRTx for the primary tumor, whereas 28 patients received nRTx for the primary tumor. There were no significant differences in the number of incomplete resections or perioperative morbidities. There was no significant difference in 5-year overall survival (28 vs. 43%, p = 0.81), recurrence-free survival (55 vs. 48%, p = 0.5), and disease-free survival (27 vs. 40%, p = 0.59). CONCLUSIONS Surgical treatment of carefully selected patients with nonmetastasized resectable LRRC after nRTx and TME for the primary tumor is feasible and can result in sustained local control and overall survival. Patients with resectable LRRC who received nRTx for the primary tumor do not have a poorer outcome than patients who did not.

Abstract
PURPOSE To analyze prognostic factors associated with survival in patients after intraoperative electrons containing resective surgical rescue of locally recurrent rectal cancer (LRRC). METHODS AND MATERIALS From January 1995 to December 2011, 60 patients with LRRC underwent extended surgery (n=38: multiorgan [43%], bone [28%], soft tissue [38%]) or nonextended (n=22) surgical resection, including a component of intraoperative electron-beam radiation therapy (IOERT) to the pelvic recurrence tumor bed. Twenty-eight (47%) of these patients also received external beam radiation therapy (EBRT) (range, 30.6-50.4 Gy). Survival outcomes were estimated by the Kaplan-Meier method, and risk factors were identified by univariate and multivariate analyses. RESULTS The median follow-up time was 36 months (range, 2-189 months), and the 1-year, 3-year, and 5-year rates for locoregional control (LRC) and overall survival (OS) were 86%, 52%, and 44%; and 78%, 53%, 43%, respectively. On multivariate analysis, R1 resection, EBRT at the time of pelvic rerecurrence, no tumor fragmentation, and non-lymph node metastasis retained significance with regard to LRR. R1 resection and no tumor fragmentation showed a significant association with OS after adjustment for other covariates. CONCLUSIONS EBRT treatment integrated for rescue, resection radicality, and not involved fragmented resection specimens are associated with improved LRC in patients with locally recurrent rectal cancer. Additionally, tumor fragmentation could be compensated by EBRT. Present results suggest that a significant group of patients with LRRC may benefit from EBRT treatment integrated with extended surgery and IOERT.

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
BACKGROUND There is a lack of outcome data beyond local recurrence rates after primary treatment in rectal cancer, despite more information being necessary for clinical decision-making. We sought to determine patient selection, therapeutic modalities and outcomes of locally recurrent rectal cancer treated with curative intent. METHODS We searched MEDLINE (1990-2010) using the medical subject headings "rectal neoplasms" and "neoplasm recurrence, local." Selection of cohort studies was based on the primary intention of treatment and availability of at least 1 outcome variable. RESULTS We included 55 cohort studies comprising 3767 patients; 8 studies provided data on the rate of intentionally curative treatment from an unselected consecutive cohort of patients (481 of 1188 patients; 40%). Patients were symptomatic with pain in 50% (796 of 1607) of cases. Overall, 3088 of 3767 patients underwent resection. The R0 resection rate was 56% (1484 of 2637 patients). The rate of external beam radiotherapy was 100% in 9 studies, 0% in 5 studies, and ranged from 12% to 97% in 37 studies. Overall postoperative mortality was 2.2% (57 of 2515 patients). Five-year survival was at least 25%, with an upper limit of 41% in 11 of 18 studies including at least 50 resections. We found a significant increase in reported survival rates over time (r2 = 0.214, p = 0.007). CONCLUSION More uniformity in treatment protocols and reporting on outcomes for locally recurrent rectal cancer is warranted. The observed improvement of reported survival rates in time is probably related to better patient selection and optimized multimodality treatment in specialized centres.

Abstract
BACKGROUND Pelvic exenteration is a potentially curative treatment for locally advanced primary or recurrent rectal cancer. OBJECTIVE This systematic review examines the current evidence regarding clinical and oncological outcomes in patients with locally advanced primary and recurrent rectal cancer who undergo pelvic exenteration. DATA SOURCES A literature search of PubMed, Medline, and the Cochrane library was undertaken, and studies published in the English language from January 2000 to August 2012 were identified. STUDY SELECTION Prospective and retrospective studies that report outcomes of pelvic exenteration for primary advanced and locally recurrent rectal cancer with or without subgroup evaluation were included for examination. MAIN OUTCOME MEASURES Oncological outcomes included 5-year survival, median survival, and local recurrence rates. Clinical outcomes included complication rates and perioperative mortality rates. RESULTS A total of 23 studies with 1049 patients were reviewed. The complication rates ranged from 37% to 100% (median, 57%) and the perioperative mortality rate ranged from 0% to 25% (median, 2.2%). The rate of local recurrence ranged from 4.8% to 61% (median, 22%). The median survival for primary advanced rectal cancers was 14 to 93 months (median, 35.5 months) and 8 to 38 months (median, 24 months) for locally recurrent rectal cancer. LIMITATIONS Our review was limited by the small sample sizes from single-institutional studies reporting outcomes over long periods of time with heterogeneity in both the disease and treatments reported. CONCLUSIONS Although the human costs and risks are significant, the potentially favorable survival outcomes make this acceptable in the absence of other effective treatment modalities that would otherwise result in debilitating symptoms that afflict patients who have advanced pelvic malignancy.

Abstract
AIM To determine the presence and duration of survival advantages was investigated for resection margin status (R0, R1 or R2) following surgery for locally recurrent rectal cancer (LRRC). METHOD A systematic review of the literature was performed for studies comparing resection margin status for LRRC. Weighted mean differences and meta-analysis of hazard ratios were used as a measure of median and overall cumulative survival. RESULTS Twenty-two studies were included, providing outcome for 1460 patients undergoing surgery for LRRC. 57% underwent an R0 resection, 25% an R1 resection and 11% an R2 resection. The most commonly performed operations were abdominoperineal excision (35%), exenteration (23%) and anterior resection (21%). The range of median survival per resection margin was R0 28-92 months, R1 12-50 months, R2 6-17 months. Patients undergoing an R0 resection survived on average for 37.6 (95% confidence interval: 23.5-51.7) months longer than those undergoing R1 resection and 53.0 (31.2-74.8) months longer than those undergoing R2 resection. This correlated to a hazard ratio of 2.03 (1.73-2.38) for R0 vs R1 and 3.41 (2.21-5.25) for R0 vs R2. Patients undergoing R1 resection survived on average 13.3 (7.23-19.4) months longer than those undergoing R2 resection [hazard ratio of 1.68 (1.33-2.12)]. CONCLUSION Patients undergoing R0 resection have the greatest survival advantage following surgery for recurrent rectal cancer. There is a survival advantage for R1 over R2 resection, but there may be no benefit of R2 resection over palliative treatment.

Abstract
BACKGROUND Approximately 10% of patients with colorectal cancer have locally advanced disease with peritoneal involvement (T4a) or invasion of adjacent organs (T4b) at the time of diagnosis. Of patients who undergo resection with curative intent, between 7 and 33% develop isolated locoregional recurrences. R0 surgical excision is potentially curative. METHODS We reviewed the literature relating to multivisceral resection for T4 or recurrent colorectal cancer. RESULTS Comprehensive staging to identify the local and systemic extent of disease is essential to determine resectability and patient suitability for a curative approach. PET scans and pelvic MRI (rectal) staging and a coordinated multispecialty input to neoadjuvant treatment, multivisceral surgical resection, reconstruction and adjuvant chemotherapy are essential. Intraoperative radiotherapy and hyperthermic intraperitoneal chemotherapy may have a role in selected patients. R0 resection can achieve 5-year local control rates for primary locally advanced and recurrent colorectal cancer of up to 89 and 38%, respectively, and overall 5-year survival up to 66 and 25%, respectively. CONCLUSION An aggressive surgical strategy as part of a multimodal strategy in the treatment of locally advanced or recurrent colorectal cancer in the absence of incurable metastatic disease affords the best prospect for long-term survival in selected patients.

Abstract
Evidence of the clinical benefit of surgery or metastasectomy for metastatic colorectal cancer to disease sites including the liver, lung, peritoneum, and pelvis as a potentially curative option is now available in the literature. The oncologic outcome of this treatment strategy achieves 5-year survival ranging between 20% and 50%. These survival gains have not been previously observed in the management of metastatic colorectal cancer. Treatment of potential surgical candidates requires a combined modality approach with systemic therapies to achieve macroscopic tumor removal and microscopic targeting of tumor deposits to achieve disease control. In nonsurgical candidates, systemic therapy, radiation therapy, and interventional oncology procedures may potentially facilitate sufficient disease downstaging for surgery. The purpose of this article is to provide a comprehensive review of the therapeutic advances in the surgical management of metastatic colorectal cancer.

Abstract
AIM Eight highly selected patients are reported, undergoing external hemipelvectomy (EHP) for malignant infiltration of the lumbosacral neural plexus. METHOD All patients were evaluated by positron emission tomography-computed tomography (PET-CT), CT and magnetic resonance imaging. No evidence of disseminated disease was found. With agreement by the multidisciplinary team, surgery was performed by a colorectal surgeon and an orthopaedic sarcoma surgeon and, if needed, by an urologist and vascular surgeon. Patients were reconstructed with either a femoral or a gluteal musculocutaneous flap. RESULTS Of the eight women [median age 54.5 (40-68) years], two had primary carcinoma and six local recurrence of a previously treated carcinoma. R0 was possible in six patients and R1 resection in two. The median duration of hospital stay was 29.5 (17-102) days. The median follow up was 8.3 (4.7-52.8) months. Three patients have died, one from postoperative complications at 5 months and two from recurrence at 5 and 52.8 months. Phantom-limb was experienced in six patients. Four patients received a prosthesis, one is considering this and one does not want a prosthesis. CONCLUSION Hemipelvectomy may be considered for a highly selected group of patients with locally advanced carcinoma or recurrence involving the lumbosacral neural plexus.

Abstract
BACKGROUND To perform complete resection of locally advanced and recurrent rectal carcinoma, total pelvic exenteration (TPE) may be attempted. We identified disease-related outcomes and prognostic factors. METHODS We conducted a single-centre review of patients who underwent TPE for rectal carcinoma over a 10-year period. RESULTS We included 28 patients in our study. After a median follow-up of 35 months, 53.6% of patients were alive with no evidence of disease. The 3-year actuarial disease-free and overall survival rates were 52.2% and 75.1%, respectively. On univariate analysis, recurrent disease, preoperative body mass index greater than 30 and lymphatic invasion were poor prognostic factors for disease-free survival, and only lymphatic invasion predicted overall survival. Additionally, multivariate analysis identified lymphatic invasion as an independent poor prognostic factor for disease-free survival in this patient population with locally advanced and recurrent rectal carcinoma. CONCLUSION Despite the significant morbidity, TPE can provide long-term survival in patients with rectal carcinoma. Additionally, lymphatic invasion on final pathology was an independent prognostic factor for disease-free survival.
