Risk factors and treatment strategies for local recurrence of locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy followed by total mesorectal excision. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108641. [PMID: 39213693 DOI: 10.1016/j.ejso.2024.108641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 07/04/2024] [Accepted: 08/23/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND Despite advancements in total mesorectal excision (TME) and neoadjuvant radiotherapy, locally advanced rectal cancer remains challenging, impacting patient quality of life and mortality. This study aimed to identify the risk factors for local recurrence in locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy (CRT) and assess treatment strategies for recurrence. METHODS This retrospective analysis included 682 patients diagnosed with locally advanced rectal cancer who were treated with neoadjuvant CRT and TME at Samsung Medical Center from 2008 to 2017. The exclusion criteria ensured a homogenous cohort. Clinical staging involved colonoscopies, computed tomography, magnetic resonance imaging, and digital rectal exam. Risk factors, treatment modalities, and oncological outcomes for local recurrence were evaluated. RESULT During a median 62-month follow-up, 47 patients (6.9 %) experienced local recurrence. The risk factors for local recurrence included a positive circumferential resection margin (CRM), venous invasion, and perineural invasion. Of the 47 patients with local recurrence, 25 (53.2 %) were considered resectable. Out of these, 23 patients underwent curative resections, and 15 (65.2 %) achieved R0 resection. Patients with R0 resections exhibited superior 5-year survival rates compared to R1-2 resection or non-surgical treatment, and there was no survival difference between R1-2 resection and non-surgical treatment. CONCLUSION In locally advanced rectal cancer, positive CRM, venous invasion, and perineural invasion were associated with local recurrence. R0 resection showed favorable outcomes, emphasizing the importance of surveillance in high-risk patients. Treatment decisions should consider these factors for improved oncologic outcomes and quality of life.

Abstract
INTRODUCTION Pelvic recurrences from rectal cancer present a challenging clinical scenario. Hyperthermia represents an innovative treatment option in combination with concurrent chemoradiation to enhance therapeutic effect. We provide the initial results of a prospective single center feasibility study (NCT02528175) for patients undergoing rectal cancer retreatment using concurrent chemoradiation and mild hyperthermia with MR-guided high intensity focused ultrasound (MR-HIFU). METHODS All patients were deemed ineligible for salvage surgery and were evaluated in a multidisciplinary fashion with a surgical oncologist, radiation oncologist and medical oncologist. Radiation was delivered to a dose of 30.6 Gy in 1.8 Gy per fraction with concurrent capecitabine. MR-HIFU was delivered on days 1, 8 and 15 of concurrent chemoradiation. Our primary objective was feasibility and toxicity. RESULTS Six patients (total 11 screened) were treated with concurrent chemoradiation and mild hyperthermia with MR-HIFU. Tumor size varied between 3.1-16.6 cm. Patients spent an average of 228 min in the MRI suite and sonication with the external transducer lasted an average of 35 min. There were no complications on the day of the MR-HIFU procedure and all acute toxicities (no grade >/=3 toxicities) resolved after completion of treatment. There were no late grade >/=3 toxicities. CONCLUSION Mild hyperthermia with MR-HIFU, in combination with concurrent chemoradiation for appropriately selected patients, is safe for localized pelvic recurrences from rectal cancer. The potential for MR-HIFU to be applied in the recurrent setting in rectal cancer treatment requires further technical development and prospective evaluation.

Abstract
OBJECTIVE To analyze risk and patterns of locoregional failure (LRF) in patients of the RAPIDO trial at 5 years. BACKGROUND Multimodality treatment improves local control in rectal cancer. Total neoadjuvant treatment (TNT) aims to improve systemic control while local control is maintained. At 3 years, LRF rate was comparable between TNT and chemoradiotherapy in the RAPIDO trial. METHODS A total of 920 patients were randomized between an experimental (EXP, short-course radiotherapy, chemotherapy, and surgery) and a standard-care group (STD, chemoradiotherapy, surgery, and optional postoperative chemotherapy). LRFs, including early LRF (no resection except for organ preservation/R2 resection) and locoregional recurrence (LRR) after an R0/R1 resection, were analyzed. RESULTS Totally, 460 EXP and 446 STD patients were eligible. At 5.6 years (median follow-up), LRF was detected in 54/460 (12%) and 36/446 (8%) patients in the EXP and STD groups, respectively ( P =0.07), in which EXP patients were more often treated with 3-dimensional-conformed radiotherapy ( P =0.029). In the EXP group, LRR was detected more often [44/431 (10%) vs. 26/428 (6%); P =0.027], with more often a breached mesorectum (9/44 (21%) vs. 1/26 (4); P =0.048). The EXP treatment, enlarged lateral lymph nodes, positive circumferential resection margin, tumor deposits, and node positivity at pathology were the significant predictors for developing LRR. Location of the LRRs was similar between groups. Overall survival after LRF was comparable [hazard ratio: 0.76 (95% CI, 0.46-1.26); P =0.29]. CONCLUSIONS The EXP treatment was associated with an increased risk of LRR, whereas the reduction in disease-related treatment failure and distant metastases remained after 5 years. Further refinement of the TNT in rectal cancer is mandated.

Abstract
Introduction and Importance Lateral lymph node dissection (LLND) for recurrent lateral pelvic lymph node metastasis could be the only surgical treatment to improve its prognosis, but is difficult and challenging technically. Case Presentation A 75-year-old Japanese man who underwent a radical laparoscopic intersphincteric resection to treat double lower rectal cancer. Computed tomography and MRI showed lower rectal wall thickening and bilateral lateral lymph node swelling. The authors scheduled and performed the LLND for recurrent lateral pelvic lymph nodes after ISR by the totally extraperitoneal (TEP) approach. The bottom of the obturators lymph node (#263D) were positive for metastasis histologically. Clinical Discussion The TEP approach is an especially effective option for the treatment of bilateral LLND. Conclusion Herein, the authors introduce our surgical technique: successful challenging treatment of the LLND by the TEP approach after intersphincteric resection of the lower rectum.

Abstract
INTRODUCTION Most lymphatic vessels in the upper rectum run parallel to the superior rectal artery and up to the inferior mesenteric artery. Here, we report a rare case of upper rectal cancer with atypical lymphatic spread. PRESENTATION OF CASE A 39-year-old woman was diagnosed with upper rectal cancer and isolated lymph node (LN) metastases to the mesorectal and right common iliac LNs. The patient underwent laparoscopic low anterior resection with targeted dissection of the right common iliac LNs. The pathological diagnosis was T3N2M0, and the patient received postoperative adjuvant chemotherapy. One year later, local recurrence was found at the sacral promontory level, where the targeted lymphadenectomy had been performed previously. The recurrent tumor was surgically resected together with the attached presacral fascia. The patient subsequently received postoperative adjuvant chemotherapy, and there was no recurrence one year after the last surgery. DISCUSSION Isolated metastases were observed in the right common iliac and mesorectal LNs. The locally recurrent tumor included lymphatic vessels running along the median sacral artery. No metastatic tumor was found in the internal iliac area at the time of the initial diagnosis nor during recurrence. Thus, this case suggests the presence of a rare metastatic route from the mesorectal LN to the common iliac LN via the median sacral lymphatics. CONCLUSION Lymphatic spread of rectal cancer may be predictable; however, rare patterns of LN metastasis can exist. The assessment of lymphatic flow is crucial for improving the oncological outcomes of rectal cancer surgery.

Abstract
BACKGROUND Transanal local excision and the use of specialized platforms has become increasingly popular for early-stage rectal cancer. Predictors and outcomes of positive resection margins following transanal local excision for early-stage rectal cancer have yet to be explored. METHODS This was a retrospective analysis of the National Cancer Database of all patients with clinical nonmetastatic node negative T1 rectal adenocarcinoma who underwent transanal local excision from 2004 to 2017. Patients with positive surgical margins were compared to those with negative resection margins to determine factors associated with predictors and outcomes of positive surgical margins after transanal local excision. The main outcome measure was overall survival. RESULTS Of 318,548 patients with rectal adenocarcinoma in the National Cancer Database, 9,078 (2.8%) met the inclusion criteria. The positive surgical margins rate was 7.4%. Predictors of positive surgical margins were older age (odds ratio, 1.03; P < .001), higher Charlson comorbidity index (odds ratio, 1.24; P = .004), poorly differentiated carcinomas (odds ratio, 1.89; P < .001), mucinous (odds ratio, 2.36; P = .003) and signet-ring cell carcinomas (odds ratio, 4.7; P = .048). Independent predictors of reduced survival were older age (hazard ratio, 1.062; P < .001), male sex (hazard ratio, 1.214; P = .011), Charlson comorbidity index 3 (hazard ratio, 1.94; P < .001), pathologic T2 (hazard ratio, 1.27; P = .036) and T3 stages (hazard ratio, 1.77; P = .006), poorly differentiated carcinomas (hazard ratio, 1.47; P = .008), and positive surgical margins (hazard ratio, 1.374; P = .018). The positive surgical margins group's median overall survival was significantly shorter (88 vs 159.3 months, P < .001). CONCLUSION Positive surgical margins after transanal local excision for early-stage node-negative rectal cancer adversely affects prognosis. Older male patients with higher Charlson comorbidity index scores and poorly differentiated mucinous or signet cell histology tumors are at risk for positive surgical margins. Patient selection according to these suggested criteria may help avoid positive surgical margins.

Abstract
Ovarian cancer represents one of the most aggressive female cancers in the world, remaining a tumor with high lethality. This study aims to present how a multidisciplinary team (MDT) approach can improve the prognosis in terms of recurrence and death of patients. In total, 448 ovarian cancer cases registered in an Italian Cancer Registry between 2012 and 2020 were included. Information on age, morphology, stage, and treatment was collected. Recurrence and death rates were reported 1 and 2 years after diagnosis, comparing MDT vs. non-MDT approaches. Ninety-three percent had microscopic confirmation, and most showed cystic-mucinous morphology. In total, 50% were older than 65 years old. The distribution by stage was 17.6%, 4%, 44.9%, and 32.6% for stages I, II, III, and IV, respectively. The women followed by the MDT were 24.1%. Disease-free survival 1-year post-diagnosis, recurrences, recurrences-deaths, and deaths were 67.5%, 14.5%, 8.4%, and 9.6%, respectively, better than the non-MDT group (46.2%, 13.2%, 20.8 %, and 19.8%, respectively) (p < 0.01). The same positive results were confirmed two years after diagnosis, particularly for stages III and IV. Albeit small numbers, the study confirms a better prognosis for women managed by MDT with fewer recurrences and deaths, especially within the first 24 months of diagnosis.

Abstract
BACKGROUND AND PURPOSE Neoadjuvant chemoradiotherapy (nCRT) is used in locally recurrent rectal cancer (LRRC) to increase chances of a radical surgical resection. Delineation in LRRC is hampered by complex disease presentation and limited clinical exposure. Within the PelvEx II trial, evaluating the benefit of chemotherapy preceding nCRT for LRRC, a delineation guideline was developed by an expert LRRC team. MATERIALS AND METHODS Eight radiation oncologists, from Dutch and Swedish expert centres, participated in two meetings, delineating GTV and CTV in six cases. Regions at-risk for re-recurrence or irradical resection were identified by eleven expert surgeons and one expert radiologist. Target volumes were evaluated multidisciplinary. Inter-observer variation was analysed. RESULTS Inter-observer variation in delineation of LRRC appeared large. Multidisciplinary evaluation per case is beneficial in determining target volumes. The following consensus regarding target volumes was reached. GTV should encompass all tumour, including extension into OAR if applicable. If the tumour is in fibrosis, GTV should encompass the entire fibrotic area. Only if tumour can clearly be distinguished from fibrosis, GTV may be reduced, as long as the entire fibrotic area is covered by the CTV. CTV is GTV with a 1 cm margin and should encompass all at-risk regions for irradical resection or re-recurrence. CTV should not be adjusted towards other organs. Multifocal recurrences should be encompassed in one CTV. Elective nodal delineation is only advised in radiotherapy-naïve patients. CONCLUSION This study provides a first consensus-based delineation guideline for LRRC. Analyses of re-recurrences is needed to understand disease behaviour and to optimize delineation guidelines accordingly.

[PMID: 35743581 PMCID: PMC9224654 DOI: 10.3390/jcm11123511] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 06/11/2022] [Accepted: 06/16/2022] [Indexed: 12/15/2022] Open
Abstract
(1) Background: The classification of locally recurrent rectal cancer (LRRC) is not currently standardized. The aim of this review was to evaluate pelvic LRRC according to the Beyond TME (BTME) classification system and to consider commonly associated primary tumour characteristics. (2) Methods: A systematic review of the literature prior to April 2020 was performed through electronic searches of the Science Citation Index Expanded, EMBASE, MEDLINE, and CENTRAL databases. The primary outcome was to assess the location and frequency of previously classified pelvic LRRC and translate this information into the BTME system. Secondary outcomes were assessing primary tumour characteristics. (3) Results: A total of 58 eligible studies classified 4558 sites of LRRC, most commonly found in the central compartment (18%), following anterior resection (44%), in patients with an 'advanced' primary tumour (63%) and following neoadjuvant radiotherapy (29%). Most patients also classified had a low rectal primary tumour. The lymph node status of the primary tumour leading to LRRC was comparable, with 52% node positive versus 48% node negative tumours. (4) Conclusions: This review evaluates the largest number of LRRCs to date using a single classification system. It has also highlighted the need for standardized reporting in order to optimise perioperative treatment planning.

Abstract
AIM Failure to achieve a radical resection as well as intraoperative rectal perforation are important risk factors for local recurrence after rectal cancer surgery, but the importance of other intraoperative adverse events for the prognosis is unknown. The aim of this study was to assess the occurrence of intraoperative adverse events during rectal cancer surgery, and to determine whether these were associated with an increased risk of local recurrence. METHODS A retrospective population-based cohort study was undertaken, including all patients in Region Västra Götaland, Sweden, who had undergone primary resection surgery for rectal cancer diagnosed between 2010 and 2014, registered in the Swedish Colorectal Cancer Registry. Data were retrieved from the registry and through review of the medical records. RESULTS In total, 1208 patients were included in the study of whom 78 (6%) developed local recurrence during the follow-up period of at least 5 years. Intraoperative adverse events were common and occurred in 62/78 (79%) of patients with local recurrence compared to 604/1130 (53%) of patients without local recurrence. In multivariate analysis intraoperative adverse events were found to be an independent risk factor for local recurrence of rectal cancer, as were nonradical resection, a high pathological T stage, the presence of lymph node metastases, type of surgery and refraining from rectal washout during anterior resection and Hartmann's procedure. CONCLUSIONS Intraoperative adverse events were found to be an independent risk factor for local recurrence of rectal cancer and could possibly be used together with other known risk factors to select patients for intensified postoperative surveillance.

Abstract
PURPOSE The standard treatment of stage II-III rectal cancer is preoperative chemoradiotherapy (CRT), followed by total mesorectal excision (TME). However, the rate of metastasis is still high following this treatment. Therefore, several adjuvant chemotherapy studies have been conducted on reducing subsequent metastases and increasing survival, although there are still no definite conclusions. METHODS We searched for published prospective randomized controlled trials comparing adjuvant chemotherapy regimens following standard preoperative CRT and curative surgery in stage II-III rectal cancer. We systematically searched Medline, Embase, and the Cochrane Library for relevant trials done from January 2004 to January 2021. Review Manager (RevMan, version 5.3) was used to analyze the data. RESULTS We initially searched 1955 studies. We screened and carefully selected four randomized controlled trials with 2897 patients. Compared to the 5-FU-based regimen group, the oxaliplatin-added regimen group attained a higher 3-year locoregional control rate (relative risk [RR] of 0.64, 95% confidence interval [CI], 0.48-0.86; p = 0.003) and 3-year distant metastasis control rate (RR of 0.82, 95% CI, 0.71-0.95; p = 0.007). The oxaliplatin-added regimen group had significantly increased 3-year disease-free survival with a hazard ratio (HR) of 0.85 (95% CI: 0.74-0.97, p = 0.020), but not overall survival (p = 0.740). Grade 3 or higher acute toxicity rates did not differ between the two groups (p = 0.190). CONCLUSION The addition of oxaliplatin to adjuvant therapy for stage II-III rectal cancer following preoperative CRT and TME may increase disease-free survival without significant increases in toxicity, but not overall survival.

Abstract
BACKGROUND Identifying preoperative risk factors of local recurrence and patterns of treatment failure resulting after rectal cancer management is important for planning treatment strategies and improving the results of multidisciplinary care. OBJECTIVE The purpose of this study was to analyze the associations between the preoperative factors and local recurrence and to investigate the local recurrence areas in patients with locally advanced lower rectal cancer who underwent lateral pelvic lymph node dissection. DESIGN The study used a retrospective cohort design. SETTINGS It was conducted at a single institution. PATIENTS Overall 469 patients with locally advanced lower rectal adenocarcinoma located below the peritoneal reflex who received curative resection with lateral pelvic lymph node dissection during 2010 to 2018 were included. MAIN OUTCOME MEASURES Independent risk factors for local recurrence were assessed using multivariate Cox regression. Local recurrence was classified into 3 areas using follow-up images. RESULTS A total of 286 patients underwent upfront surgery, 132 patients received neoadjuvant chemotherapy followed by surgery, and 51 patients received preoperative chemoradiotherapy followed by surgery. Eighty-six patients (18.3%) were extramural venous invasion positive, and 113 patients (24.1%) were circumferential resection margin positive. The median follow-up period was 46 months. Local recurrence showed significant association with extramural venous invasion positive (HR = 2.596 (95% CI, 1.321-5.102); p = 0.006) or circumferential resection margin positive (HR = 2.298 (95% CI, 1.158-4.560); p = 0.017). The incidence of local recurrence was observed in 51 patients (10.8%), with the pelvic plexus and internal iliac area being the most frequent (6.6%), followed by the central pelvis area (3.8%), and was markedly low in the obturator area (0.4%). LIMITATIONS This was a retrospective, single-institution design. CONCLUSIONS Extramural venous invasion status and circumferential resection margin status were associated with a high local recurrence rate in patients who underwent lateral pelvic lymph node dissection. In addition, local recurrence in the obturator area was low compared with that in other areas. See Video Abstract at http://links.lww.com/DCR/B683.

Abstract
PURPOSE To compare the characteristics and outcomes of rectal cancer patients with local recurrence at a perianastomotic site (PA), a surgical field (SF) site, or in lateral lymph nodes (LLN). METHODS A total of 114 consecutive patients who underwent surgery for recurrent, non-metastatic rectal cancer at a single comprehensive cancer center between 1997 and 2012 were grouped on the basis of radiographic assessment of type of recurrence: PA, 76 (67%) patients; SF, 25 (22%) patients; LLN, 13 (11%) patients. Demographic, clinical, and pathological features were compared between the three groups, as were disease-free survival (DFS) and overall survival (OS). RESULTS Recurrence type was associated with positive circumferential margin in the primary resection (PA, 4 [6%]; SF, 4 [19%]; LLN, 3 [25%]; P = 0.027), prior neoadjuvant therapy for the primary tumor (PA, 57 [75%]; SF, 18 [72%]; LLN, 4 [31%]; P = 0.007), and location of the primary tumor in the upper rectum (PA, 33 [45%]; SF, 5 [23%]; LLN, 1 [8%]; P < 0.001). Patients with PA had longer median DFS (PA, 5.1 years; SF, 1.5 years; LLN, 1.2 years; P = 0.036). There was a non-significant trend toward longer OS and higher rates of R0 resection for PA. CONCLUSION Type of recurrence after salvage surgery for locally recurrent rectal cancer is associated with longer DFS in patients with PA recurrence.

Abstract
We aimed to evaluate whether a short distal resection margin (< 1 cm) was associated with local recurrence in patients with locally advanced rectal cancer who underwent preoperative chemoradiotherapy. Patients with rectal cancer who underwent preoperative chemoradiotherapy followed by curative surgery were divided into two groups based on the distal resection margin (≥ 1 cm and < 1 cm). In total, 507 patients were analyzed. The median follow-up duration was 48.9 months. The 3-year local recurrence rates were 2% and 8% in the ≥ 1 cm and < 1 cm groups, respectively (P < 0.001). Multivariable analysis revealed that a distal resection margin of < 1 cm was a significant risk factor for local recurrence (P = 0.008). Subgroup analysis revealed that a distal resection margin of < 1 cm was not an independent risk factor for local recurrence in the ypT0-1 group. However, among patients with tumor stages ypT2-4, the cumulative 3-year incidences of local recurrence were 2.3% and 9.8% in the ≥ 1 cm and < 1 cm groups, respectively (P = 0.01). A distal resection margin of < 1 cm might influence local recurrence rates in patients with locally advanced rectal cancer undergoing preoperative chemoradiotherapy, especially in patients with tumor stages ypT2-4.

Abstract
Colorectal cancer is one of the most prevalent tumours, but with improved treatment and early detection, its prognosis has greatly improved in recent years. However, when the tumour is locally advanced at diagnosis or if there is local recurrence, it is more difficult to perform a complete tumour resection, and there may be a residual macroscopic tumour. In this paper, we review the literature on residual macroscopic tumour resections, concerning both locally advanced primary tumours and recurrences, evaluating the main problems encountered, the treatments applied, the prognosis and future perspectives in this field.

Abstract
PURPOSE The aim of this study is to correlate locoregional relapse with radiation therapy volumes in patients with rectal cancer treated with neoadjuvant chemoradiation in the ACCORD 12/0405-PRODIGE 02 trial. PATIENTS AND METHODS We identified patients who had a locoregional relapse included in ACCORD 12's database. We studied their clinical, radiological, and dosimetric data to analyze the dose received by the area of relapse. RESULTS 39 patients (6.5%) presented 54 locoregional relapses. Most of the relapses were in-field (n = 21, 39%) or marginal (n = 13, 24%) with only six out-of-field (11%), 14 could not be evaluated. Most of them happened in the anastomosis, the perirectal space, and the usual lymphatic drainage areas (presacral and posterior lateral lymph nodes). Only patients treated for a lower rectum adenocarcinoma had a relapse outside of the treated volume. 2 patients with T4 tumors extending into anterior pelvic organs had relapses in anterior lateral and external iliac lymph nodes. CONCLUSIONS Lowering the upper limit of the treatment field for low rectal tumors increased the risk of out of the field recurrence. For very low tumors, including the inguinal lymph nodes in the treated volume should be considered. Recording locoregional involvement, treated volumes, and relapse areas in future prospective trials would be of paramount interest to refine delineation guidelines.

Transanal total mesorectal excision for stage II or III rectal cancer: pattern of local recurrence in a tertiary referral center. Surg Endosc 2021; 35:7191-7199. [PMID: 33398553 DOI: 10.1007/s00464-020-08200-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Accepted: 11/19/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND For mid and low rectal cancer, transanal total mesorectal excision (TaTME) has been established as an alternative approach to laparoscopic surgery. However, there are concerns about an unexpected pattern of local recurrence. This study aimed to analyze the pattern of local recurrence for patients treated with TaTME in a tertiary referral center. METHODS A retrospective single-center analysis was performed. Since 2011, all patients with rectal cancer undergoing TaTME with curative intent were prospectively included in a standardized database. Patients with tumors within 12 cm, clinical stage II or III were included. The primary endpoint of the study was the overall local recurrence rate, together with a critical analysis of the patterns of local failures. RESULTS Two hundred and five patients were included in this analysis. At the time of surgery, patients had a mean age of 67.1 years (SD 12.3), and 66.8% were male. Neoadjuvant therapy was administered in 73.7%. Mesorectal specimen quality was complete or near-complete in 98.5%, while circumferential resection margin was ≤ 1 mm (including T4 tumors) in 11.8%. After a median follow-up of 34.3 months (95% CI 30.1-38.5), 3.4% (n = 7) presented with local recurrent disease. Six out of the seven patients were also diagnosed with hematogenous metastases. Of the seven patients, three presented with at least one of the following risk factors: T4 tumor, N2 disease, incomplete mesorectal specimen, or positive CRM. Local failure was noted posteriorly (n = 3), laterally (n = 2), anteriorly (n = 1), and in the axial compartment (n = 1). Median time to relapse was 31.5 months (10.3-40.9). The median follow-up after local recurrence was 7.9 (95% CI 6.7-9.1) months, with an overall survival of 85.7%. CONCLUSIONS TaTME provided satisfactory local recurrence outcomes, and the most common patterns of failure were in the central pelvis.

Abstract
BACKGROUND AND AIMS The aim of this study was to analyse the landscape of publications on rectal cancer (RC) over the past 25 years by machine learning and semantic analysis. METHODS Publications indexed in PubMed under the Medical Subject Headings (MeSH) term 'Rectal Neoplasms' from 1994 to 2018 were downloaded in September 2019. R and Python were used to extract publication date, MeSH terms and abstract from the metadata of each publication for bibliometric assessment. Latent Dirichlet allocation was applied to analyse the text from the articles' abstracts to identify more specific research topics. Louvain algorithm was used to establish a topic network resulting in identifying the relationship between the topics. RESULTS A total of 23,492 papers published were identified and analysed in this study. The changes of research focus were analysed by the changing of MeSH terms. Studied contents extracted from the publications were divided into five areas, including surgical intervention, radiotherapy and chemotherapy intervention, clinical case management, epidemiology and cancer risk as well as prognosis studies. CONCLUSIONS The number of publications indexed on RC has expanded rapidly over the past 25 years. Studies on RC have mainly focused on five areas. However, studies on basic research, postoperative quality of life and cost-effective research were relatively lacking. It is predicted that basic research, inflammation and some other research fields might become the potential hotspots in the future.

Abstract
Presacral anastomotic sinus is recognized as a complication of anastomotic leakage in patients with rectal cancer. Active inflammation in the anastomotic sinus can masquerade as pelvic recurrence of rectal cancer. We present a case of progressive inflammation in anastomotic sinus demonstrated by serial FDG PET/CT scans. Despite its benign nature, increased FDG uptake in this nonnegligible condition, which could lead to further detrimental complications including secondary cancer, may have clinical implications.

Abstract
Background: There is no clear consensus on the use of re-irradiation (reRT) in the management of locally recurrent rectal cancer (LRRC). The aim of the present study was to investigate all reRT administered for rectal cancer at a large referral institution and to evaluate patient outcomes and toxicity.Material and methods: All patients with rectal cancer were identified who had received previous pelvic radiotherapy (RT) and underwent reRT during 2006-2016. Medical records and RT details of the primary tumor treatments and rectal cancer recurrence treatments were registered, including details on reRT, chemotherapy, surgery, adverse events, and long-term outcomes.Results: Of 77 patients who received ReRT, 67 had previously received pelvic RT for rectal cancer and were administered reRT for LRRC. Re-irradiation doses were 30.0-45.0 Gy, most often given as hyperfractionated RT in 1.2-1.5 Gy fractions twice daily with concomitant capecitabine. The median time since initial RT was 29 months (range, 13-174 months). Of 36 patients considered as potentially resectable, 20 underwent surgery for LRRC within 3 months after reRT. Operated patients had better 3-year overall survival (OS) (62%) compared to those who were not operated (16%; HR 0.32, p = .001). The median gross tumor volume (GTV) was 107 cm3, and 3-year OS was significantly better in patients with GTV <107 cm3 (44%) compared to patients with GTV ≥107 cm3 (21%; HR 0.52, p = .03).Conclusion: Three-year survival was significantly better for patients who underwent surgery after reRT or who had small tumor volume. Prospective clinical trials are recommended for further improvements in patient selection, outcomes, and toxicity assessment.

Abstract
In the era of neoadjuvant chemoradiotherapy/radiotherapy and total mesorectal excision, overall oncological outcomes after curative resection of rectal cancer are excellent, with local recurrence rates as low as 5–10%. However, lateral nodal disease is a major cause of local recurrence after neoadjuvant chemoradiotherapy/radiotherapy and total mesorectal excision. Patients with lateral nodal disease have a local recurrence rate of up to 30%. The oncological benefits of lateral pelvic lymph node dissection (LPLND) in reducing local recurrence, particularly in the lateral compartment, have been demonstrated. Although LPLND is not standard in Western countries, technical improvements in minimally invasive surgery have resulted in rapid technical standardization of this complicated procedure. The feasibility and short- and long-term outcomes of laparoscopic and robotic LPLND have been reported widely. A minimally invasive approach has the advantages of less bleeding and providing a better surgical view of the deep pelvic anatomy than an open approach. With precise autonomic nerve preservation, postoperative genitourinary dysfunction has been reported to be minimal. We review recent evidence on the management of lateral nodal disease in rectal cancer and technical improvements of LPLND, focusing on laparoscopic and robotic LPLND.

Abstract
Despite advances in surgical techniques and chemoradiation therapy, recurrent rectal cancer remains a cause of morbidity and mortality. After successful treatment of rectal cancer, patients are typically enrolled in a surveillance strategy that includes imaging as studies have shown improved prognosis when recurrent rectal cancer is detected during imaging surveillance versus based on development of symptoms. Additionally, patients who experience a complete clinical response with chemoradiation therapy may elect to enroll in a "watch-and-wait" strategy that includes imaging surveillance rather than surgical resection. Factors that increase the likelihood of recurrence, patterns of recurrence, and the imaging appearances of recurrent rectal cancer are reviewed with a focus on CT, PET CT, and MR imaging.

Abstract
Lateral lymph node dissection (LLND) for recurrence of lateral pelvic lymph node metastasis after rectal cancer surgery is technically demanding because of the need for re-do surgery. We herein report a novel technique of laparoscopic LLND via a totally extraperitoneal (TEP) approach. Since October 2018, we have performed LLND based on a TEP approach, called "M TEP LLND", with two cases treated. By peeling in the caudal direction in the dorsal layer of the rectus abdominis muscle, a working space is created once the extraperitoneal space is reached, and LLND is performed. All lateral pelvic lymph node dissection procedures have been successfully completed, and there have been no intraoperative or postoperative complications. This procedure allows TEP-experienced colorectal surgeons to perform safe and complete LLND without any influence of intraperitoneal adhesion or intestinal obstruction. M TEP LLND is less invasive than the conventional intraperitoneal approach and appears to be useful, particularly for recurrence of lateral pelvic lymph node metastasis.

Abstract
BACKGROUND Population-based studies of treatment of locally recurrent rectal cancer (LRRC) are lacking. The aim was to investigate the surgical treatment of patients with LRRC at a national population-based level. METHODS All patients undergoing abdominal resection for primary rectal cancer between 1995 and 2002 in Sweden with LRRC as a first event were included. Detailed information about treatment, complications and outcomes was collected from the medical records. The patients were analysed in three groups: patients who had resection of the LRRC, those treated without tumour resection and patients who received best supportive care only. RESULTS In all, 426 patients were included in the study. Of these, 149 (35·0 per cent) underwent tumour resection, 193 (45·3 per cent) had treatment without tumour resection and 84 (19·7 per cent) received best supportive care. Abdominoperineal resection was the most frequent surgical procedure, performed in 65 patients (43·6 per cent of those who had tumour resection). Thirteen patients had total pelvic exenteration. In total, 63·8 per cent of those whose tumour was resected had potentially curative surgery. After tumour resection, 62 patients (41·6 per cent) had a complication within 30 days. Patients who received surgical treatment without tumour resection had a lower complication rate but a significantly higher 30-day mortality rate than those who underwent tumour resection (10 versus 1·3 per cent respectively; P = 0·002). Of all patients included in the study, 22·3 per cent had potentially curative treatment and the 3-year survival rate for these patients was 56 per cent. CONCLUSION LRRC is a serious condition with overall poor outcome. Patients undergoing curative surgery have an acceptable survival rate but substantial morbidity. There is room for improvement in the management of patients with LRRC.

Abstract
BACKGROUND For rectal cancer, multimodality therapeutic approach is necessary to prevent local recurrence and distant metastasis. However, the efficacy of additional treatments, such as neoadjuvant chemoradiotherapy (nCRT), neoadjuvant chemotherapy (NAC), and lateral pelvic lymph node dissection (LPLND), has not been scrutinized. METHODS Recurrence patterns were categorized into local recurrence and distant metastasis. Local recurrence was classified into two types: (1) pelvic cavity recurrence and (2) LPLN recurrence. First, we analyzed the risk factors for each recurrence pattern. Second, based on the status of clinically suspected involvement of circumferential resection margin (cCRM), the efficacy of additional treatments was investigated. RESULTS A total of 240 patients was enrolled. nCRT was performed for 25 (10%), NAC was for 46 (19%), and LPLND was for 35 patients (15%). As the recurrence patterns, pelvic cavity recurrence occurred in 15 (6%), LPLN recurrence in 8 (3%), and distant metastasis in 42 patients (18%). Five-year overall survival and relapse-free survival were 87% and 70%, respectively. Multivariate analysis indicated that pelvic cavity recurrence was associated with cCRM status and tumor histology, that LPLN recurrence was with serum carcinoembryonic antigen level and LPLN swelling, and that distant metastasis was with clinical N category. In the cCRM-positive subgroup (n = 66), cumulative rate of pelvic cavity recurrence was lower in the nCRT group than in the NAC or non-NAC/nCRT group (P = 0.02 and 0.09, respectively). CONCLUSION cCRM status was associated with pelvic cavity recurrence, and LPLN swelling was with LPLN recurrence. nCRT could reduce pelvic cavity recurrence in cCRM-positive subgroup.

Impact of VMAT-IMRT compared to 3D conformal radiotherapy on anal sphincter dose distribution in neoadjuvant chemoradiation of rectal cancer. Radiat Oncol 2018; 13:237.

Abstract
Background Neoadjuvant radio- or chemoradiation (nIRT) therapy is the standard treatment for loco-regional advanced rectal cancer patients of the lower or middle third. Currently, intensity modulated radiation therapy (IMRT) is not the recommended radiation technique even though IMRT has advantages compared to 3D-radiation regarding dose sparing to organs at risk like small bowel and urinary bladder. So far, the benefit of IMRT concerning the anal sphincter complex is not examined. With this study we intended to evaluate the dose distribution on the anal sphincters of rectal cancer patients treated with IMRT in comparison with 3D-techniques. Methods We selected 16 patients for the IMRT-group and 16 patients for the 3D-group with rectal cancer of the middle third who were treated in our institute. All patients received 45 Gy in a chemoradiation protocol. Patients in both groups were matched regarding stage, primary tumor distance to the anal verge and size of the tumor. We delineated the internal and external anal sphincters, the addition of both sphincters and the levator ani muscle in all patients. Subsequently, we evaluated and compared dose parameters of the different sphincters in both groups and analysed the configuration of the isodoses in the area of the caudal radiation field, respectively. Results Most of the relevant dose parameters of the caudal sphincters (Dmean, Dmedian, V10–V40) were significantly reduced in the IMRT-group compared to the 3D-group. Accordingly, the isodoses at the caudal edge of the target volume in the IMRT group demonstrated a steep dose fall. The levator ani muscle always was included into the planned target volumes and received the full dose in both groups. Conclusions The modern VMAT-IMRT can significantly reduce the dose to the anal sphincters for rectal cancer patients of the middle third who were treated with conventional chemoradiation therapy.

Abstract
OBJECTIVE Colorectal surgeons report difficulty in positioning surgical devices in males, particularly those with a narrower pelvis. The objectives of this study were to (1) characterize the anatomy of the pelvis and surrounding soft tissue from magnetic resonance and computed tomography scans from 10 average males (175 cm, 78 kg) and (2) develop a model representing the mean configuration to assess variability. METHODS The anatomy was characterized from existing scans using segmentation and registration techniques. Size and shape variation in the pelvis and soft tissue morphology was characterized using the Generalized Procrustes Analysis to compute the mean configuration. RESULTS There was considerable variability in volume of the psoas, connective tissue, and pelvis and in surface area of the mesorectum, pelvis, and connective tissue. Subject height was positively correlated with mesorectum surface area (P = .028, R2 = 0.47) and pelvis volume ( P = .041, R2 = 0.43). The anterior-posterior distance between the inferior pelvic floor muscle and pubic symphysis was positively correlated with subject height ( P = .043, r = 0.65). The angle between the superior mesorectum and sacral promontory was negatively correlated with subject height ( P = .042, r = -0.65). The pelvic inlet was positively correlated with subject weight ( P = .001, r = 0.89). CONCLUSIONS There was considerable variability in organ volume and surface area among average males with some correlations to subject height and weight. A physical trainer model created from these data helped surgeons trial and assess device prototypes in a controllable environment.

Abstract
Background The cranial border of the target volume (TV) in rectal cancer patients treated with neoadjuvant chemoradiation (nCRT) is mostly defined at the level of L5/S1. However, current studies have shown that relapse cranially of the target volume after neoadjuvant nCRT and surgery is very rare. A reduction of cranial TV margins could be reasonable to reduce toxicity to the organs at risk (OAR). In this study we compared the dose distribution to the OAR for different cranial longitudinal margins using a dose-volume histogram (DVH) analysis. Methods Ten patients with loco regional advanced rectal cancer were analysed retrospectively. All patients were planned for Volumetric Arc Therapy Radiation Therapy (VMAT). Next to the original PTV (PTV0), three new planning target volumes (PTV) were defined for each patient: The PTV0 reduced by 1 cm, 2 cm and 3 cm on cranial extension. For each PTV a treatment plan with a total dose of 50.4 Gy with daily doses of 1.8 Gy was calculated. Dose to the OAR were evaluated and compared. Results For the bone marrow, the small bowel and the peritoneal space all clinically relevant relative dose parameters (V10-V50) as well as the Dmedian could be significantly reduced with every cranial target volume reduction of 1 cm. For V10 of the peritoneal space the dose could be nearly halved with a 3 cm shortened TV. After TV reduction of 3 cm also for the urinary bladder a significant dose reduction of the Dmedian could be achieved. Conclusions Considering the very low recurrence rates in the TME and IMRT era, the distribution patterns of these relapses as well as the relevant side effects of nCRT, we would agree with existing recommendations of reduction of the cranial target volume in nCRT treated rectal cancer patients.

Abstract
Background Local recurrence of colorectal cancer is a major cause of morbidity and mortality that usually implies a worse prognosis. Its etiopathogenesis is still a subject of debate. Recurrence on the perineal wound caused by anal retractor device is rarely reported. Case presentation We present the case of a 75-year-old woman with perineal skin recurrence on the site of Lone Star Retractor™ from rectal adenocarcinoma. The patient underwent a curative proctectomy followed by a hand-sewn coloanal anastomosis using Lone Star Retractor™ 2 years ago for a tumor of the lower rectum. The recurrence was most likely caused by the seeding of exfoliated tumor cells into the perianal skin which was abraded by the retractor. Conclusion This case is the fourth case reported in the literature and highlights the importance of the use of less traumatic endoanal retractors to prevent such perianal recurrence. Recurrence on the perineal wound caused by anal retractor device is rare but possible. Further studies are needed to define preventive measures able to reduce cutaneous implants.

Abstract
BACKGROUND To analyze the local distribution of pelvic recurrence after total mesorectal excision, with a view to simplifying the formulation of optimal individualized radiotherapy plans. METHODS We retrospectively investigated the data of 168 patients diagnosed with recurrent pelvic cancer treated at Fudan University Shanghai Cancer Center between January 2008 and December 2012. The following were collected depending on availability: operative report, histological report, specimen photographs, initial preoperative images, images confirming local recurrence, and clinical history. RESULTS A total of 203 lesions of local recurrence were identified. The most common sites of pelvic recurrence were the mesorectum, including the anastomotic stoma in 53.0% of cases; presacral space in 27.4%, and pelvic floor and perineum in 21.4% the cases. Recurrence was most common in the lower pelvic region (i.e., below the upper border of the acetabulum), accounting for approximately 76.2% (128 cases) of cases. In patients with mid-rectal and distal rectal carcinoma. CONCLUSIONS Patients with pelvic cancer may benefit by individualized treatment plans aimed at achieving a balance between tumor control and minimal risk of irradiation-induced toxicity.

Abstract
Local excision (LE) of early-stage rectal cancer avoids the morbidity associated with radical surgery but has historically been associated with inferior oncologic outcomes. Newer techniques, including transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS), have been developed to improve the quality of LE and extend the benefits of LE to tumors in the more proximal rectum. This article provides an overview of conventional LE, TEM, and TAMIS techniques, including indications for their use and pertinent literature on their associated outcomes for rectal cancer.

Abstract
Localized rectal adenocarcinoma is a heterogeneous disease and current treatment recommendations are based on a preoperative multidisciplinary evaluation. High-resolution magnetic resonance imaging and endoscopic ultrasound are complementary to do a locoregional accurate staging. Surgery remains the mainstay of treatment and preoperative therapies with chemoradiation (CRT) or short-course radiation (SCRT) must be considered in more locally advanced cases. Novel strategies with induction chemotherapy alone or preceding or after CRT (SCRT) and surgery are in development.

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 Natural orifice translumenal endoscopic surgery (NOTES) has always made more sense in the colorectal field where the target organ for entry houses the pathology. To address the question whether an adequate total mesorectal excision (TME) for rectal cancer can be performed from a transanal bottoms-up approach, we performed a case-matched study. METHODS Starting in 2009, transanal TME (taTME) surgery was selectively used for rectal cancer after neoadjuvant therapy and prospectively entered into a database. Between March 2012 and February 2014, 17 consecutive taTME rectal cancer patients were identified and case-matched to multiport laparoscopic TME (MP TME) based on age, body mass index, uT stage, radiation dose, level in the rectum, and procedure. Perioperative outcomes, morbidity, mortality, local recurrence, completeness of TME, and radial and distal margins were analyzed. Statistically significant differences were identified using Student's t test. RESULTS There were 12 transanal abdominal transanal (TATA)/5 abdominoperineal resection procedures in each group. Data regarding overall/taTME/MP TME are as follows: % positive-circumferential margin: 2.9/0/5.9 % (p = 0.32). Distal margin: 0/0/0 %. Complete or near-complete TME: 97.1/100/94.1 % (p = 0.32). Incomplete TME 2.9/0/5.9 % (p = 0.32). Local recurrence: 2.9/5.9/0 % (p = 0.32). There were no perioperative mortalities. Morbidity in each group: 26.4/23.5/29.4 % (p = 0.79). There were no differences in perioperative or postoperative outcomes except days to clear liquids (1/2 days, p = 0.03) and largest incision length (1.3/2.6 cm, p = 0.05). CONCLUSIONS We demonstrated no differences in perioperative/postoperative outcomes or pathologic TME outcomes of transanal or bottoms-up TME compared to standard laparoscopic TME. TaTME is a promising progressive approach to NOTES and deserves additional evaluation.

Abstract
Background Angiogenesis plays a pivotal role in malignant tumor progression. The count of blood microvessels of the tumor has been recognized as an indicator of malignant potential of the tumors and provides the ability to predict tumors recurrence. The role endoglin in the Dukes B rectal cancer is still unexplored. The aims of this study were to examine immunohistochemical expression of endoglin in resected rectal cancer and investigate the relationship of tumor recurrence and other clinicopathological variables to the endoglin-assessed microvessel density of the tumor tissue and distal resection margins. Methods The study included 95 primary rectal adenocarcinomas, corresponding to 95 distal and 95 proximal resection margin specimens from surgical resection samples. Tumor specimens were paraffin embedded, and immunohistochemical staining for the CD105 endothelial antigen was performed to count CD105-MVD. For exact measurement of the CD105-MVD used, a computer-integrated system Alphelys Spot Browser 2 was used. Results The MVD was significantly higher in the tumor samples compared with the distal resection margins (p < 0.0001) and the proximal resection margins (p < 0.0001). There was no significant difference in the MVD between distal and proximal resection margins (p = 0.147). The type of surgical resection was a significant factor for determining the recurrence of tumors (p = 0.0104). There was no significant effect of patients’ age, gender, tumor location, grade of differentiation, histological tumor type, and the size and depth of tumor invasion on the recurrence of the tumor. The recurrence rate was significantly higher in the low CD105-MVD group of patients than in the high CD105-MVD group of patients (log rank test, p = 0.0406). Result of the multivariate analysis showed that the type of surgery (p = 0.0086), MVD tumors (p = 0.0385), and MVD of proximal resection margin (p = 0.0218) were the independent prognostic factors for the recurrent tumors. Conclusions CD105-assessed MVD could help to identify patients with more aggressive disease and increased risk of developing tumor recurrence after surgical treatment in stage II rectal cancer (RC).

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
BACKGROUND Pelvic oligo-recurrence is common in rectal cancer patients, and some could not achieve radical resection. OBJECTIVE The study was to analyze long-term outcomes and prognostic factors associated with survival in patients treated with intensity-modulated radiation therapy (IMRT). METHODS Study participants were identified from rectal patients with pelvic oligo-recurrence without distant metastases, who were not suitable for surgery (n=135). Patients were recommended to receive concurrent chemotherapy in the course of IMRT (median dose 64.5 Gy, range: 45-70 Gy). Additionally, 24.4% (33/135) of patients received radical surgery after preoperative radiotherapy. Median time to pelvic failure was 25.4 months (range: 1-144 months). With a median follow-up period of 45.5 months (range: 3-104 months), 5-year overall survival (OS) and disease-free survival (DFS) were 55.6% and 45.5%, respectively. RESULTS In univariate survival analysis, OS stratified by subsites indicated that 5-year OS for anastomotic recurrence (80.5%) was better than for anterior recurrence (57.7%) and other pelvic oligo-recurrences (44.5%) (P=0.005). Five-year DFS in the three groups was 60.3%, 49% and 36.6%, respectively (P=0.037). In multivariate survival analysis, pelvic oligo-recurrence and symptomatic recurrence patterns were independently associated with OS in recurrent rectal cancer after pelvic radiotherapy (RT). CONCLUSIONS These results indicate that RT for rectal cancer patients with pelvic oligo-recurrence had favorable prognosis, especially for patients with anastomotic recurrence.

Abstract
AIM The lateral pelvic lymph nodes are one of the major sites and sources of local recurrence (LR) after surgery for rectal cancer. Salvage lateral pelvic lymph node dissection (LPLD) is potentially curative, but the value of laparoscopic surgery in such cases is unknown. Our aim was to report the technical details of laparoscopic salvage LPLD for LR at these nodes after rectal cancer surgery. METHOD The study was based on nine patients who underwent laparoscopic salvage LPLD for LR at the lateral pelvic lymph nodes after surgery for rectal cancer. The safety and feasibility of this procedure were determined. RESULTS The median operation time was 381 min and the median estimated blood loss was 130 ml. There were no conversions. Adjacent structures removed en bloc were the pelvic plexus in four patients, the internal iliac artery in seven patients and the seminal vesicle in one patient. The median number of metastatic lymph nodes was 1 (range 1-11). CONCLUSION Our novel technique of laparoscopic salvage LPLD for LR at the lateral pelvic lymph nodes is safe and feasible.

Abstract
BACKGROUND We assessed the magnetic resonance imaging (MRI) findings of lateral pelvic lymph node (LPLN) metastasis in patients with advanced low-rectal cancer treated with preoperative chemoradiotherapy (CRT) and LPLN dissection (LPLD) for clinically suspected LPLN metastasis. Our aim was to identify the optimal indications for LPLD. METHODS The study population consisted of 77 patients with advanced low-rectal cancer who underwent LPLD for clinically suspicious LPLN metastasis after preoperative CRT. MRI findings before/after CRT, clinical factors, and LPLN metastasis were evaluated. RESULTS LPLN metastasis was confirmed in 31 patients (40.3 %). Metastasis was significantly higher in patients with LPLNs with a short-axis diameter ≥8 mm than in patients with LPLNs with a short-axis diameter <8 mm before CRT (75 vs. 20 %, P < 0.0001). LPLN metastasis was also significantly higher in patients with LPLNs with a short-axis diameter >5 mm than in patients with LPLNs with a short-axis diameter ≤5 mm after CRT (75 vs. 20 %, P < 0.0001). Multivariate analysis showed the independent association of female sex [P = 0.0192; odds ratio (OR) 5.616; 95 % confidence interval (CI) 1.315-28.942], pre-CRT short-axis diameter of the LPLN ≥8 mm (P = 0.0047; OR 9.188; 95 % CI 1.948-54.366), and CRT without induction systemic chemotherapy (P = 0.0285; OR 9.235; 95 % CI 1.241-106.947) with LPLN metastasis. CONCLUSIONS MRI before CRT is useful to predict LPLN metastasis and to determine the indications for LPLD.
