[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.

Multivisceral resection of advanced colon and rectal cancer: a prospective multicenter observational study with propensity score analysis of the morbidity, mortality, and survival. Innov Surg Sci 2023; 8:61-72. [PMID: 38058778 PMCID: PMC10696939 DOI: 10.1515/iss-2023-0027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 07/14/2023] [Indexed: 12/08/2023] Open
Abstract
Objectives In the surgical treatment of colorectal carcinoma (CRC), 1 in 10 patients has a peritumorous adhesion or tumor infiltration in the adjacent tissue or organs. Accordingly, multivisceral resection (MVR) must be performed in these patients. This prospective multicenter observational study aimed to analyze the possible differences between non-multivisceral resection (nMVR) and MVR in terms of early postoperative and long-term oncological treatment outcomes. We also aimed to determine the factors influencing overall survival. Methods The data of 25,321 patients from 364 hospitals who had undergone surgery for CRC (the Union for International Cancer Control stages I-III) during a defined period were evaluated. MVR was defined as (partial) resection of the tumor-bearing organ along with resection of the adherent and adjacent organs or tissues. In addition to the patients' personal, diagnosis (tumor findings), and therapy data, demographic data were also recorded and the early postoperative outcome was determined. Furthermore, the long-term survival of each patient was investigated, and a "matched-pair" analysis was performed. Results From 2008 to 2015, the MVR rates were 9.9 % (n=1,551) for colon cancer (colon CA) and 10.6 % (n=1,027) for rectal cancer (rectal CA). CRC was more common in men (colon CA: 53.4 %; rectal CA: 62.0 %) than in women; all MVR groups had high proportions of women (53.6 % vs. 55.2 %; pairs of values in previously mentioned order). Resection of another organ frequently occurred (75.6 % vs. 63.7 %). The MVR group had a high prevalence of intraoperative (5.8 %; 12.1 %) and postoperative surgical complications (30.8 % vs. 36.4 %; each p<0.001). Wound infections (colon CA: 7.1 %) and anastomotic insufficiencies (rectal CA: 8.3 %) frequently occurred after MVR. The morbidity rates of the MVR groups were also determined (43.7 % vs. 47.2 %). The hospital mortality rates were 4.9 % in the colon CA-related MVR group and 3.8 % in the rectal CA-related MVR group and were significantly increased compared with those of the nMVR group (both p<0.001). Results of the matched-pair analysis showed that the morbidity rates in both MVR groups (colon CA: 42.9 % vs. 34.3 %; rectal CA: 46.3 % vs. 37.2 %; each p<0.001) were significantly increased. The hospital lethality rate tended to increase in the colon CA-related MVR group (4.8 % vs. 3.7 %; p=0.084), while it significantly increased in the rectal CA-related MVR group (3.4 % vs. 3.0 %; p=0.005). Moreover, the 5-year (yr) overall survival rates were 53.9 % (nMVR: 69.5 %; p<0.001) in the colon CA group and 56.8 % (nMVR: 69.4 %; p<0.001) in the rectal CA group. Comparison of individual T stages (MVR vs. nMVR) showed no significant differences in the survival outcomes (p<0.05); however, according to the matched-pair analysis, a significant difference was observed in the survival outcomes of those with pT4 colon CA (40.6 % vs. 50.2 %; p=0.017). By contrast, the local recurrence rates after MVR were not significantly different (7.0 % vs. 5.8 %; both p>0.05). The risk factors common to both tumor types were advanced age (>79 yr), pT stage, sex, and morbidity (each hazard ratio: >1; p<0.05). Conclusions MVR allows curation by R0 resection with adequate long-term survival. For colon or rectal CA, MVR tended to be associated with reduced 5-year overall survival rates (significant only for pT4 colon CA based on the MPA results), as well as, with a significant increase in morbidity rates in both tumor entities. In the overall data, MVR was associated with significant increases in hospital lethality rates, as indicated by the matched-pair analysis (significant only for rectal CA).

Oncologic outcomes after laparoscopic versus open multivisceral resection for local advanced colorectal cancer: A meta-analysis. Asian J Surg 2023; 46:6-12. [PMID: 35568616 DOI: 10.1016/j.asjsur.2022.02.047] [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: 10/22/2021] [Revised: 02/21/2022] [Accepted: 02/25/2022] [Indexed: 12/16/2022] Open
Abstract
Laparoscopic (lap) colectomies for advanced colorectal cancer (CRC) often require resection of other organs. We systematically reviewed currently available literature on lap multi-visceral resection for CRC, with regard to short- and long-term oncological outcomes, and compared them with open procedures. We performed a systematic literature search in MEDLINE, EMBASE, Google Scholar and PubMed from inception to November 30, 2020. The aim of this study was to synthesize short-term and oncological outcomes associated with laparoscopic versus open surgery. Pooled proportions and risk ratios (RRs) were calculated using an inverse variance method. We included six observational cohort studies published between 2012 and 2020 (lap procedures: n = 262; open procedures: n = 273). Collectively, they indicated that postoperative complications were significantly more common after open surgeries than lap surgeries (RR: 0.53; 95% confidence interval [CI]: 0.39-0.72; P < 0.00001), but the two approaches did not significantly differ in positive resection margins (RR: 0.75; 95% CI: 0.38-1.50; P = 0.42), local recurrence (RR: 0.66; 95% CI: 0.28-1.62; P = 0.37), or (based on two evaluable studies) 5-year OS (RR: 0.70; 95% CI: 0.46-1.04; P = 0.08) or 5-year DFS (RR: 0.86; 95% CI: 0.67-1.11) for T4b disease. In conclusion, laparoscopic and open multi-visceral resections for advanced CRC have comparable oncologic outcomes. Although a randomized study would be ideal for further research, no such studies are currently available.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2022; 48:2284-2291. [PMID: 35031157 DOI: 10.1016/j.ejso.2021.12.471] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 11/23/2021] [Accepted: 12/29/2021] [Indexed: 12/13/2022]
Abstract
OBJECTIVES To review the evidence regarding surgical advances in the management of primary locally advanced rectal cancer. BACKGROUND The management of rectal cancer has evolved significantly in recent decades, with improved (neo)adjuvant treatment strategies and enhanced perioperative protocols. Centralization of care for complex, advanced cases has enabled surgeons in these units to undertake more ambitious surgical procedures. METHODS A Pubmed, Ovid, Embase and Cochrane database search was conducted according to the predetermined search strategy. The review protocol was prospectively registered with PROSPERO (CRD42021245582). RESULTS 14 studies were identified which reported on the outcomes of 3,188 patients who underwent pelvic exenteration (PE) for primary rectal cancer. 50% of patients had neoadjuvant radiotherapy. 24.2% underwent flap reconstruction, 9.4% required a bony resection and 34 patients underwent a major vascular excision. 73.9% achieved R0 resection, with 33.1% experiencing a major complication. Median length of hospital stay ranged from 13 to 19 days. 1.6% of patients died within 30 days of their operation. Five-year overall survival (OS) rates ranged 29%-78%. LIMITATIONS The studies included in our review were mostly single-centre observational studies published prior to the introduction of modern neoadjuvant treatment regimens. It was not possible to perform a meta-analysis on the basis that most were non-randomized, non-comparative studies. CONCLUSIONS Pelvic exenteration offers patients with locally advanced rectal cancer the chance of long-term survival with acceptable levels of morbidity. Increased experience facilitates more radical procedures, with the introduction of new platforms and/or reconstructive options.

Abstract
Liposarcoma includes tumors with a wide range of malignancies, from mostly benign to malignant. We report a case of a 73 year-old man who was admitted for urination and defecation disorder. Contract computed tomography (CT) revealed a mass of approximately 21 cm occupying the pelvis, bladder, ureter, prostate, and rectum being compressed by the tumor. Since intraoperative mass bleeding was predicted, we embolized the tumor nutrition artery and performed a total pelvic exenteration. Regarding the course of the operation, SSI and pelvic infection were developed after the operation. The patient was discharged 21 days after surgery. Moreover, there is no evidence of local recurrence and distant metastasis at 18 months after surgery. Furthermore, in giant pelvic liposarcoma, it is useful to identify a nutritional artery of a giant tumor by angiography before surgery, and surgical resection can be safely done by performing preoperative transcatheter arterial embolization.

Abstract
BACKGROUND There are several strategies in the management of locally recurrent rectal cancer (LRRC) with the optimum treatment yet to be established. This systematic review aims to compare oncological outcomes in patients undergoing surgery for LRRC who underwent neoadjuvant radiotherapy or chemoradiotherapy (CRT), adjuvant CRT, surgery only or surgery and intraoperative radiotherapy (IORT). METHODS A literature search of MEDLINE, EMBASE and CINAHL was performed for studies that reported data on oncological outcomes for the different treatment modalities in patients with LRRC from January 1990 to January 2022. Weighted means were calculated for the following outcomes: postoperative resection status, local control, and overall survival at 3 and 5 years. RESULTS Fifteen studies of 974 patients were included and they received the following treatment: 346 neoadjuvant radiotherapy, 279 neoadjuvant CRT, 136 adjuvant CRT, 189 surgery only, and 24 surgery and IORT. The highest proportion of R0 resection was found in the neoadjuvant CRT group followed by neoadjuvant radiotherapy and adjuvant CRT groups (64.07% vs 52.46% vs 47.0% respectively). The neoadjuvant CRT group had the highest mean 5-year local control rate (49.50%) followed by neoadjuvant radiotherapy (22.0%). Regarding the 5-year overall survival rate, the neoadjuvant CRT group had the highest mean of 34.92%, followed by surgery only (29.74%), neoadjuvant radiotherapy (28.94%) and adjuvant CRT (20.67%). CONCLUSIONS The findings of this systematic review suggest that neoadjuvant CRT followed by surgery can lead to improved resection status, long-term disease control and survival in the management of LRRC. However, treatment strategies in LRRC are complex and further comparisons, particularly taking into account previous treatments for the primary rectal cancer, are required.

Image-guided navigation for locally advanced primary and locally recurrent rectal cancer: evaluation of its early cost-effectiveness. BMC Cancer 2022; 22:504. [PMID: 35524234 PMCID: PMC9074374 DOI: 10.1186/s12885-022-09561-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 04/17/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND A first pilot study showed that an image-guided navigation system could improve resection margin rates in locally advanced (LARC) and locally recurrent rectal cancer (LRRC) patients. Incremental surgical innovation is often implemented without reimbursement consequences, health economic aspects should however also be taken into account. This study evaluates the early cost-effectiveness of navigated surgery compared to standard surgery in LARC and LRRC. METHODS A Markov decision model was constructed to estimate the expected costs and outcomes for navigated and standard surgery. The input parameters were based on pilot data from a prospective (navigation cohort n = 33) and retrospective (control group n = 142) data. Utility values were measured in a comparable group (n = 63) through the EQ5D-5L. Additionally, sensitivity and value of information analyses were performed. RESULTS Based on this early evaluation, navigated surgery showed incremental costs of €3141 and €2896 in LARC and LRRC. In LARC, navigated surgery resulted in 2.05 Quality-Adjusted Life Years (QALYs) vs 2.02 QALYs for standard surgery. For LRRC, we found 1.73 vs 1.67 QALYs respectively. This showed an Incremental Cost-Effectiveness Ratio (ICER) of €136.604 for LARC and €52.510 for LRRC per QALY gained. In scenario analyses, optimal utilization rates of the navigation technology lowered the ICER to €61.817 and €21.334 for LARC and LRRC. The ICERs of both indications were most sensitive to uncertainty surrounding the risk of progression in the first year after surgery, the risk of having a positive surgical margin, and the costs of the navigation system. CONCLUSION Adding navigation system use is expected to be cost-effective in LRRC and has the potential to become cost-effective in LARC. To increase the probability of being cost-effective, it is crucial to optimize efficient use of both the hybrid OR and the navigation system and identify subgroups where navigation is expected to show higher effectiveness.

Abstract
PURPOSE The application of augmented reality technology to the partial hepatectomy procedure has high practical significance, but the existing augmented reality navigation system has major drawbacks in the display and registration methods, which result in low precision. The augmented reality surgical navigation system proposed in this study has been improved in the above two aspects, which can significantly improve the surgical accuracy. METHODS The use of optical see-through head-mounted displays for imaging displays can prevent doctors from reconstructing the patient's two-dimensional image information in their minds and reduce the psychological burden of doctors. In the registration process, the biomechanical properties of the liver are introduced, and a non-rigid registration method based on biomechanics is proposed and realized by a meshless algorithm. In addition, this study uses the moving grid algorithm to carry out clinical experiments on ex-vivo pig liver for experimental verification. RESULTS The mark-based interactive registration error is 4.21 ± 1.6 mm, and the registration error is reduced after taking the biomechanical properties of the liver into account, which is - 0.153 ± 0.398 mm. The cutting error of the liver model is 0.159 ± 0.292 mm. In addition, with the aid of the navigation system proposed in this paper, the experiment of ex-vivo pig liver cutting was completed with an error of - 1.164 ± 0.576 mm. CONCLUSIONS As a proof-of-concept study, the augmented reality navigation system proposed in this study improves the traditional image-guided surgery in terms of display and registration methods, and the feasibility of the system is verified by ex-vivo pig liver experiments. Therefore, the navigation system has a certain guiding significance for clinical surgery.

Abstract
Background Pelvic exenteration for locally advanced rectal cancer (LARC) and locally recurrent (LRRC) rectal cancer provides radical resection and local control, but is associated with considerable morbidity. The aim of this study was to determine risk factors, including nutritional status and body composition, for postoperative morbidity and survival after pelvic exenteration in patients with LARC or LRRC. Methods Patients with LARC or LRRC who underwent total or posterior pelvic exenteration in a tertiary referral centre from 2003 to 2018 were analysed retrospectively. Nutritional status was assessed using the Malnutrition Universal Screening Tool (MUST). Body composition was estimated using standard-of-care preoperative CT of the abdomen. Logistic regression analyses were performed to identify risk factors for complications with a Clavien–Dindo grade of III or higher. Risk factors for impaired overall survival were calculated using Cox proportional hazards analysis. Results In total, 227 patients who underwent total (111) or posterior (116) pelvic exenteration were analysed. Major complications (Clavien–Dindo grade at least III) occurred in 82 patients (36.1 per cent). High risk of malnutrition (MUST score 2 or higher) was the only risk factor for major complications (odds ratio 3.99, 95 per cent c.i. 1.76 to 9.02) in multivariable analysis. Mean follow-up was 44.6 months. LRRC (hazard ratio (HR) 1.61, 95 per cent c.i. 1.04 to 2.48) and lymphovascular invasion (HR 2.20, 1.38 to 3.51) were independent risk factors for impaired overall survival. Conclusion A high risk of malnutrition according to the MUST is a strong risk factor for major complications in patients with LARC or LRRC undergoing exenteration surgery.

Abstract
OBJECTIVE To describe quality of life (QOL) and survival outcomes following pelvic exenteration (PE) in old and young patients. BACKGROUND PE is a management option for complete resection in locally advanced pelvic cancers. Few studies have examined the impact of age on the outcome in elderly patients following PE. PATIENTS AND METHODS Prospective cohort of consecutive patients undergoing partial and complete PE between 1994 and 2019. Patients were divided into a younger (< 65 years) or older cohort (≥ 65 years) based on their age. QoL was assessed using the SF-36 and FACT-C questionnaires and survival estimated using the Kaplan-Meier method. RESULTS For 710 patients who underwent PE during the study period, FACT-C total score was significantly better in the elderly during the whole follow-up period of 5 years. Mental component score (SF-36) was significantly better at baseline (p = 0.008) and at 24 months postoperatively (p = 0.042), in the elderly group. Median overall survival was 75 months in the younger cohort and 53 months in the older cohort (p = 0.004). In subgroup analysis, older patients with recurrent or primary rectal cancer had a median survival of 37 and 70 months, respectively. Postoperative cardiovascular complications were greater in the elderly cohort (p < 0.001). CONCLUSIONS Elderly patients had better overall QoL but lower survival that is probably related to cardiovascular complications rather than to cancer as both groups had similar R0 resection rate. Hence, the elderly population should be considered equally for PE.

Abstract
BACKGROUND Locoregional recurrence (LR) remains a problem for patients with lower rectal cancer despite standardized surgery and improved neoadjuvant treatment regimens. Lateral pelvic lymph node dissection (LPLND) has been routine practice for some time in the Orient/East, but other regions have concerns about morbidity. As perioperative care and surgical approaches are refined, this has been revisited for selected patients. The question as to whether LPLND improves oncological outcomes was explored here. METHODS A systematic review of patients who underwent TME with or without LPLND from 2000 to 2020 was performed. The primary endpoint was the rate of LR between the two groups. RESULTS Seven papers met the predefined search criteria in which 2000 patients underwent TME alone, while 1563 patients had TME and LPLND. The rate of LR was marginally higher with TME alone when compared with TME plus LPLND, but this result was not statistically significant (9.8 vs 9.4%, odds ratio 0.75, 95% CI 0.41-1.38, *p = 0.35). In addition, four studies reported on distant recurrence rates, with TME and LPLND showing a slight reduction in overall rates (27.3 vs 29.9%, respectively, OR 0.65, 95% CI 0.45-0.92, *p = 0.02). CONCLUSION The addition of LPLND to TME is not associated with a significantly lower risk of LR in patients who undergo surgery for lower rectal cancer.

Abstract
IMPORTANCE The percentage of tumor-positive surgical resection margin rates in patients treated for locally advanced primary or recurrent rectal cancer is high. Image-guided navigation may improve complete resection rates. OBJECTIVE To ascertain whether image-guided navigation during rectal cancer resection improves complete resection rates compared with surgical procedures without navigation. DESIGN, SETTING, AND PARTICIPANTS This prospective single-center nonrandomized controlled trial was conducted at the Netherlands Cancer Institute-Antoni van Leeuwenhoek in Amsterdam, the Netherlands. The prospective or navigation cohort included adult patients with locally advanced primary or recurrent rectal cancer who underwent resection with image-guided navigation between February 1, 2016, and September 30, 2019, at the tertiary referral hospital. Clinical results of this cohort were compared with results of the historical cohort, which was composed of adult patients who received rectal cancer resection without image-guided navigation between January 1, 2009, and December 31, 2015. INTERVENTION Rectal cancer resection with image-guided navigation. MAIN OUTCOMES AND MEASURES The primary end point was the complete resection rate, measured by the amount of tumor-negative resection margin rates. Secondary outcomes were safety and usability of the system. Safety was evaluated by the number of navigation system-associated surgical adverse events. Usability was assessed from responses to a questionnaire completed by the participating surgeons after each procedure. RESULTS In total, 33 patients with locally advanced or recurrent rectal cancer were included (23 men [69.7%]; median [interquartile range] age at start of treatment, 61 [55.0-69.0] years). With image-guided navigation, a radical resection (R0) was achieved in 13 of 14 patients (92.9%; 95% CI, 66.1%-99.8%) after primary resection of locally advanced tumors and in 15 of 19 patients (78.9%; 95% CI, 54.4%-94.0%) after resection of recurrent rectal cancer. No navigation system-associated complications occurred before or during surgical procedures. In the historical cohort, 142 patients who underwent resection without image-guided navigation were included (95 men [66.9%]; median [interquartile range] age at start of treatment, 64 [55.0-70.0] years). In these patients, an R0 resection was accomplished in 85 of 101 patients (84.2%) with locally advanced rectal cancer and in 20 of 41 patients (48.8%) with recurrent rectal cancer. A significant difference was found between the navigation and historical cohorts after recurrent rectal cancer resection (21.1% vs 51.2%; P = .047). For locally advanced primary tumor resection, the difference was not significant (7.1% vs 15.8%; P = .69). Surgeons stated in completed questionnaires that the navigation system improved decisiveness and helped with tumor localization. CONCLUSIONS AND RELEVANCE Findings of this study suggest that image-guided navigation used during rectal cancer resection is safe and intuitive and may improve tumor-free resection margin rates in recurrent rectal cancer.

Abstract
Objective The objective of the study was to evaluate computed tomography (CT)-guided 125I implantation for the treatment of recurrent and malignant pelvic tumors. Materials and Methods Fifteen cases of pelvic malignant tumors were studied. Tumor length/diameter was 4-10 cm (average: 6.8 ± 2.3 cm). In patients with pelvic recurrence or metastasis of malignant tumors, comprehensive treatment, including surgery, chemotherapy, or radiotherapy, was performed alongside CT-guided 125I implantation. The follow-up clinical benefit rate, rate of pain relief, quality of life score, and status of any complications were analyzed. Results The patients were followed up for 6 months after the operation, and evaluation of lesions revealed complete response (CR) in 3/15 cases, partial response (PR) in 8/15 cases, stable disease in 3/15 cases, and progressive disease in 1/15 cases. The total effective rate (CR + PR) was 73.3% (11/15), and the pain relief rate was 86.6% (13/15). No bleeding, pelvic abscesses, intestinal fistulas, intestinal perforations, or other complications were reported. Conclusions When using CT-guided 125I implantation, patients with malignant abdominal tumors undergo a convenient operation, sustain little trauma, and have an improved quality of life.

Abstract
BACKGROUND AND OBJECTIVES The primary treatment for locally advanced cases of cervical cancer is chemoradiation followed by high-dose brachytherapy. When this treatment fails, pelvic exenteration (PE) is an option in some cases. This study aimed to develop recommendations for the best management of patients with cervical cancer undergoing salvage PE. METHODS A questionnaire was administered to all members of the Brazilian Society of Surgical Oncology. Of them, 68 surgeons participated in the study and were divided into 10 working groups. A literature review of studies retrieved from the National Library of Medicine database was carried out on topics chosen by the participants. These topics were indications for curative and palliative PE, preoperative and intraoperative evaluation of tumor resectability, access routes and surgical techniques, PE classification, urinary, vaginal, intestinal, and pelvic floor reconstructions, and postoperative follow-up. To define the level of evidence and strength of each recommendation, an adapted version of the Infectious Diseases Society of America Health Service rating system was used. RESULTS Most conducts and management strategies reviewed were strongly recommended by the participants. CONCLUSIONS Guidelines outlining strategies for PE in the treatment of persistent or relapsed cervical cancer were developed and are based on the best evidence available in the literature.

Abstract
Negative circumferential resection margins (CRM) are the cornerstone for the curative treatment of locally advanced rectal cancer (LARC). However, in up to 18.6% of patients, tumor-positive resection margins are detected on histopathology. In this proof-of-concept study, we investigated the feasibility of optical molecular imaging as a tool for evaluating the CRM directly after surgical resection to improve tumor-negative CRM rates. Methods: LARC patients treated with neoadjuvant chemoradiotherapy received an intravenous bolus injection of 4.5 mg of bevacizumab-800CW, a fluorescent tracer targeting vascular endothelial growth factor A, 2-3 d before surgery (ClinicalTrials.gov identifier: NCT01972373). First, for evaluation of the CRM status, back-table fluorescence-guided imaging (FGI) of the fresh surgical resection specimens (n = 8) was performed. These results were correlated with histopathology results. Second, for determination of the sensitivity and specificity of bevacizumab-800CW for tumor detection, a mean fluorescence intensity cutoff value was determined from the formalin-fixed tissue slices (n = 42; 17 patients). Local bevacizumab-800CW accumulation was evaluated by fluorescence microscopy. Results: Back-table FGI correctly identified a tumor-positive CRM by high fluorescence intensities in 1 of 2 patients (50%) with a tumor-positive CRM. For the other patient, low fluorescence intensities were shown, although (sub)millimeter tumor deposits were present less than 1 mm from the CRM. FGI correctly identified 5 of 6 tumor-negative CRM (83%). The 1 patient with false-positive findings had a marginal negative CRM of only 1.4 mm. Receiver operating characteristic curve analysis of the fluorescence intensities of formalin-fixed tissue slices yielded an optimal mean fluorescence intensity cutoff value for tumor detection of 5,775 (sensitivity of 96.19% and specificity of 80.39%). Bevacizumab-800CW enabled a clear differentiation between tumor and normal tissue up to a microscopic level, with a tumor-to-background ratio of 4.7 ± 2.5 (mean ± SD). Conclusion: In this proof-of-concept study, we showed the potential of back-table FGI for evaluating the CRM status in LARC patients. Optimization of this technique with adaptation of standard operating procedures could change perioperative decision making with regard to extending resections or applying intraoperative radiation therapy in the case of positive CRM.

Abstract
Background The free flap transfer of a latissimus dorsi flap (LDF) for the closure of sacral wound defects after pelvic exenteration and radiation therapy offers a successful tool of the plastic surgeon. This case report shows the successful coverage using an upstream arterio-venous (AV) loop in combination with an LDF. Case presentation We describe the case of a patient who underwent a pelvic exenteration and radiation therapy due to a local recurrence of rectal cancer. The initially used VRAM flap could not ensure a satisfactorily wound closure. An interdisciplinary approach first yielded an AV loop using both greater saphenous veins and was connected to the arteria and vena femoris followed by a free LDF transfer, which was performed 11 days later. The result was an excellent reconstructive and plastic coverage of the sacral wound defect with a well-perfused LDF. The long-term result showed a perfectly integrated flap in the sacral region. Conclusion We recommend the free LDF for the coverage of large wound defects in irradiated areas after the failure of VRAM flap. If an AV loop is necessary within the flap transfer, we recommend conducting two procedures to guarantee the perfusion of the AV loop.

Shiba S, Okamoto M, Kiyohara H, Ohno T, Kaminuma T, Asao T, Ojima H, Shirabe K, Kuwano H, Nakano T. Prospective Observational Study of High-Dose Carbon-Ion Radiotherapy for Pelvic Recurrence of Rectal Cancer (GUNMA 0801). Front Oncol 2019; 9:702. [PMID: 31417874 PMCID: PMC6684773 DOI: 10.3389/fonc.2019.00702] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2019] [Accepted: 07/15/2019] [Indexed: 11/13/2022] Open
Abstract
Background and purpose: Favorable clinical outcomes of carbon-ion radiotherapy for pelvic recurrence of rectal cancer have been described by previous prospective phase I/II and II studies; however, these studies were performed at a single institution. Therefore, we conducted a prospective observational study aimed at exploring whether carbon-ion radiotherapy for post-operative pelvic recurrence of rectal cancer provides a less invasive local treatment strategy with higher cure rates than other anticancer treatments. Materials and methods: Patients (1) with pelvic recurrence of rectal cancer, as confirmed by histology or diagnostic imaging; (2) without distant metastasis; (3) who had undergone curative resection of their primary disease and regional lymph nodes, without gross or microscopic residual disease; and (4) with radiographically measurable tumors were included in this study. The total carbon-ion radiotherapy dose for all patients was 73.6 Gy [relative biological effectiveness (RBE)] administered in 16 fractions once daily for 4 days a week (Tuesday to Friday). Results: A total of 28 patients were enrolled between October 2011 and July 2017. The median follow-up duration was 38.9 months. The 3-year overall survival, local control, and progression-free survival rates were 92, 86, and 31%, respectively. At the time of the analysis, 4 patients had local recurrence, and 7 had died of rectal cancer. None of the patients developed grade 3 or higher acute toxicities. Late toxicities occurred in 2 and 7 patients who developed grade 3 pelvic infection and grade 2 peripheral neuropathy, respectively. Conclusion: Carbon-ion radiotherapy for pelvic recurrence of rectal cancer showed favorable clinical outcomes and is a highly curative and less invasive local treatment.

[DOI: 10.13105/wjma.v7.i6.269] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Revised: 06/07/2019] [Accepted: 06/17/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Multivisceral resections (MVR) are often necessary to reach clear resections margins but are associated with relevant morbidity and mortality. Factors associated with favorable oncologic outcomes and elevated morbidity rates are not clearly defined.
AIM To systematically review the literature on oncologic long-term outcomes and morbidity and mortality in cancer surgery a systematic review of the literature was performed.
METHODS PubMed was searched for relevant articles (published from 2000 to 2018). Retrieved abstracts were independently screened for relevance and data were extracted from selected studies by two researchers.
RESULTS Included were 37 studies with 3112 patients receiving MVR for colorectal cancer (1095 for colon cancer, 1357 for rectal cancer, and in 660 patients origin was not specified). The most common resected organs were the small intestine, bladder and reproductive organs. Median postoperative morbidity rate was 37.9% (range: 7% to 76.6%) and median postoperative mortality rate was 1.3% (range: 0% to 10%). The median conversion rate for laparoscopic MVR was 7.9% (range: 4.5% to 33%). The median blood loss was lower after laparoscopic MVR compared to the open approach (60 mL vs 638 mL). Lymph-node harvest after laparoscopic MVR was comparable. Report on survival rates was heterogeneous, but the 5-year overall-survival rate ranged from 36.7% to 90%, being worst in recurrent rectal cancer patients with a median 5-year overall survival of 23%. R0 -resection, primary disease setting and no lymph-node or lymphovascular involvement were the strongest predictors for long-term survival. The presence of true malignant adhesions was not exclusively associated with poorer prognosis.
Included were 16 studies with 1.600 patients receiving MVR for gastric cancer. The rate of morbidity ranged from 11.8% to 59.8%, and the main postoperative complications were pancreatic fistulas and pancreatitis, anastomotic leakage, cardiopulmonary events and post-operative bleedings. Total mortality was between 0% and 13.6% with an R0 -resection achieved in 38.4% to 100% of patients. Patients after R0 resection had 5-year overall survival rates of 24.1% to 37.8%.
CONCLUSION MVR provides, in a selected subset of patients, the possibility for good long-term results with acceptable morbidity rates. Unlikelihood of achieving R0 -status, lymphovascular- and lymph -node involvement, recurrent disease setting and the presence of metastatic disease should be regarded as relative contraindications for MVR.

The effect of preoperative nutritional status on postoperative complications and overall survival in patients undergoing pelvic exenteration: A multi-disciplinary, multi-institutional cohort study. Am J Surg 2019; 218:275-280. [PMID: 30982571 DOI: 10.1016/j.amjsurg.2019.03.021] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2018] [Revised: 03/23/2019] [Accepted: 03/28/2019] [Indexed: 01/21/2023]
Abstract
INTRODUCTION Optimization of preoperative nutritional status has been recommended and associated with improved outcomes for other oncologic procedures, but has not been studied in patients undergoing pelvic exenteration. METHODS A retrospective chart review of 199 patients was conducted. Overall survival (OS) was calculated using the Kaplan-Meier method and multivariate analysis was performed with Cox proportional hazards. RESULTS 199 patients underwent PE with 61 (31%), 78 (40%) and 58 (29%) patients having colorectal, gynecologic and urologic histological diagnoses, respectively. Median OS following PE was 25 months. Preoperative serum albumin <3.5 g/dL was associated with worsened OS (HR 1.661; 95% CI 1.052-2.624) as well as increased incidence of any postoperative complication (85.9% vs 72.3%, p = 0.034), but was not associated with 90-day mortality (11.3% vs 7.9%, p = 0.457). CONCLUSION Poor preoperative nutritional status is associated with increased complications and decreased OS. Surgeons should maximize preoperative nutritional status to improve perioperative outcomes and long-term survival.

Abstract
BACKGROUND Pelvic exenteration (PE) is a complex and challenging surgical procedure. The reported results of this procedure for primary and recurrent disease are limited and conflicting. METHODS This study analyzed patient outcomes after all PEs performed in the authors' department between October 2001 and December 2016. Relevant patient data were obtained from a prospective database. Morbidity and mortality were reported for all patients. For patients with malignant disease, differences in perioperative outcomes, prognostic indicators for overall survival, and local and systemic disease recurrence were analyzed using uni- and multivariate analyses. RESULTS The study enrolled 187 patients. Of the 183 patients with malignant disease, 63 (38.2%) had primary locally advanced tumors and 115 (62.5%) had recurrent tumors. The 10-year overall survival rate was 63.5% for the patients with primary tumors that were curatively resected and 20.9% for the patients with recurrent disease (p = 0.02). The 10-year survival rate for the patients with extrapelvic disease who underwent curative resection was 37%. Multivariable analysis identified margin positivity (p < 0.01), surgery lasting longer than 7 h (p = 0.02), and recurrent disease (p < 0.01) as predictors of poor survival. Multivariate analysis of local and systemic disease recurrence showed recurrent disease (p < 0.01) as the only significant prognostic factor. CONCLUSIONS Pelvic exenteration has good long-term results, even for patients with extrapelvic disease. The oncologic outcome for patients with recurrent disease is worse than for patients with primary disease. However, even for these patients, long-time survival is possible.

Abstract
BACKGROUND Pelvic exenteration represents the best treatment option for cure of locally advanced or recurrent rectal cancer. This systematic review sought to evaluate current literature regarding short and long term treatment outcomes and long term survival following pelvic exenteration. METHODS A systematic search of the MEDLINE, PubMed and Ovid databases was conducted to identify suitable articles published between 2001 and 2016. The article search was performed in line with Cochrane methodology and reported according to the Preferred Reporting Items for Systematic reviews and Meta-analyses statement. RESULTS Sixteen studies were included in the final analysis, incorporating 1016 patients. Sixty-three percent of patients were male and median patient age was 59 years. Median operating time was 7.2 h with median blood loss of 1.9 l. Median postoperative stay was 17 days with a median 30-day mortality of 0. Complication rates were 31.6-86% with a return to theatre rate of 14.6%. Median R0 resection rate was 74% and was higher for primary cancer (82.6% versus 58% for recurrent cancer). Mean overall survival was 31 months and median 5-year survival was 32%. Recurrently identified indicators of adverse outcome included R1/2 resection, preoperative pelvic pain and previous abdominoperineal resection of the rectum. CONCLUSIONS Pelvic exenteration remains a major operation associated with significant morbidity and mortality. Despite advances in preoperative assessment and staging, R1 resection rates remain high. There is also a high degree of variability of reporting outcomes and standardisation of this process would aid comparison of results between centres and drive forward research in this area.

Abstract
BACKGROUND Pelvic exenteration carries significant risks of morbidity and mortality. Preoperative management is therefore crucial, and the exenteration procedure is usually performed in an elective setting. In cases of rectal cancer, however, tumor-related complications may cause a patient's condition to deteriorate rapidly, despite optimal management. Urgent pelvic exenteration then may be an option for these patients. OBJECTIVE This study aims to compare the outcomes of pelvic exenteration between the urgent and elective settings. DESIGN This is a retrospective study. SETTING This study was conducted at King Chulalongkorn Memorial Hospital between February 2006 and June 2012. PATIENTS Fifty-three patients with locally advanced rectal cancer were included. INTERVENTION All patients underwent pelvic exenteration for locally advanced rectal cancer. They were assigned to urgent and elective setting groups according to their preoperative conditions. The urgent setting group included patients who required urgent pelvic exenteration because of intestinal obstruction, bowel perforation, bleeding, or uncontrolled sepsis, despite optimal management preoperatively. MAIN OUTCOME MEASURES Twenty-six patients were classified in the urgent setting group, and 27 were classified in the elective setting group. Three-year overall and disease-free survivals were compared between the 2 groups. Thirty-day postoperative morbidity and mortality were also studied. RESULTS Three-year overall survival was 62.2% and 54.4% in the elective and urgent groups (p = 0.7), whereas three-year disease-free survival was 43% and 63.8% (p = 0.33). The median follow-up time was 33 months. Thirty-day morbidity did not differ between the 2 groups (p = 0.49). A low serum albumin level was a significant risk factor for complications. There was no postoperative mortality in this study. LIMITATIONS This was a retrospective study performed at 1 institution, and it lacked quality-of-life scores. CONCLUSION Pelvic exenteration in an urgent setting is feasible and could offer acceptable outcomes. See Video Abstract at http://links.lww.com/DCR/A591.

Abstract
BACKGROUND Pelvic exenteration is the only radical treatment for locally advanced (ARC) or recurrent (RRC) rectal cancers. The long-term results of the procedure are variably reported in the literature, with recent series suggesting similar survival between ARC and RRC. The study aimed to analyze and compare the long-term survival and perioperative outcomes of patients undergoing pelvic exenteration for ARC and RRC in a tertiary center. MATERIALS AND METHODS This was a retrospective analysis of prospectively collected data. Comparison of variables was performed using Chi-square, Fisher's exact or Wilcoxon rank sum test as appropriate. The Kaplan Meier method was used to analyze the disease-free survival (DFS) and the log-rank test to compare the two groups. RESULTS Since 2002, 46 patients underwent pelvic exenteration for ARC (28, 60.9%) and RRC (18, 39.1%). The groups had comparable characteristics, perioperative results, including postoperative complications, and rate of adjuvant chemotherapy. A R0 resection was obtained in 71.4% and 55.6% (p 0.41) and a T4 stage was diagnosed in 75% and 94.4% (p 0.22) of ARC and RRC patients, respectively. After a median follow-up time of 32.5 and 56.6 months (p 0.01), the 5-year DFS was significantly lower in the RRC group (23.6 vs 46.2%, p 0.006), even after exclusion of R1 cases (30 vs 54.5%, p 0.044). CONCLUSION The long-term disease free survival of patients undergoing pelvic exenteration is significantly worse when the procedure is performed for RRC, regardless of the tumor involvement of the resection margins.

Abstract
Background The aim of the study was to present an update concerning several imaging modalities in diagnosis, staging and pre-surgery treatment response assessment in locally advanced rectal cancer (LARC). Modalities include: traditional morphological magnetic resonance imaging (MRI), functional MRI such as dynamic contrast enhanced MRI (DCE-MRI) and diffusion weighted imaging (DWI). A systematic review about the diagnostic accuracy in neoadjuvant therapy response assessment of MRI, DCE-MRI, DWI and Positron Emission Tomography/Computed Tomography (PET/CT) has been also reported. Methods Several electronic databases were searched including PubMed, Scopus, Web of Science, and Google Scholar. All the studies included in this review reported findings about therapy response assessment in LARC by means of MRI, DCE-MRI, DWI and PET/CT with details about diagnostic accuracy, true and false negatives, true and false positives. Forest plot and receiver operating characteristic (ROC) curves analysis were performed. Risk of bias and the applicability at study level were calculated. Results Twenty-five papers were identified. ROC curves analysis demonstrated that multimodal imaging integrating morphological and functional MRI features had the best accuracy both in term of sensitivity and specificity to evaluate preoperative therapy response in LARC. DCE-MRI following to PET/CT showed high diagnostic accuracy and their results are also more reliable than conventional MRI and DWI alone. Conclusions Morphological MRI is the modality of choice for rectal cancer staging permitting a correct assessment of the disease extent, of the lymph node involvement, of the mesorectal fascia and of the sphincter complex for surgical planning. Multimodal imaging and functional DCE-MRI may also help in the assessment of treatment response allowing to guide the surgeon versus conservative strategies and/or tailored approach such as “wait and see” policy.

Short- and long-term outcomes following pelvic exenteration for gynae-oncological and colorectal cancers: A 9 year consecutive single-centre cohort study. Int J Surg 2017; 43:38-45.

Abstract
OBJECTIVES Radical pelvic exenteration can be undertaken for locally invasive or recurrent disease in both colorectal and gynaecological malignancies. In the UK this procedure is usually undertaken by the respective surgical specialties who have undergone divergent surgical training. This study describes and compares outcomes between colorectal and gynae-oncological teams following pelvic exenteration for primary and recurrent gynaecological and colorectal cancers in a single-centre multi-disciplinary team. METHOD A retrospective review of consecutive pelvic exenteration patients undertaken over a nine-year period in a tertiary referral centre. Analyses comparing short- and long-term morbidity and mortality outcomes were undertaken by chi-square test for categorical variables and Mann-Whitney U for continuous variables. Cumulative survival rates were calculated according to the Kaplan-Meier method and factors associated with recurrence and survival determined using a Cox regression model. RESULTS Thirty-four exenterations were undertaken; fourteen colorectal and twenty gynae-oncological. Morbidity was seen in 50% of colorectal and 75% of gynae-oncological patients. Recurrence was seen earlier and with greater frequency in the gynaeoncology group (44.4% and median time 11 months) than the colorectal group (21.4%, median time 41 months; p > 0.05). Survival in the gynae-oncology group was also lower than the colorectal group at 1-year (69.6% vs. 92.9%) and 5-years (58.0% vs. 92.9%; p = 0.115). The majority of gynae-oncological mortality occurred within 3-years of surgery, whilst the majority of mortality in the colorectal group was after 5-years. CONCLUSION Long-term patient outcome measures, including disease recurrence and 5-year survival, for colorectal exenteration appear better than for gynaeoncology patients, however, no statistical significant difference exists between short-term outcome measures between specialties. This is likely to be caused by different baseline pathologies and disease pattern influencing longer term prognosis but may also be a function of differing surgical thresholds and patient selection bias between specialties. Peri-operative and short-term morbidity appear equivalent despite divergent surgical backgrounds and training.

Abstract
AIM Pelvic exenteration is a complex surgical procedure associated with considerable morbidity. Quality of life (QoL) is a crucial metric of surgical outcome. The aim of this review was to assess the QoL following pelvic exenteration for locally advanced rectal cancer (LARC) and local recurrent rectal cancer (LRRC). METHOD A comprehensive search of studies published between 2000 and 2016 that examined QoL outcome following pelvic exenteration was performed. Functional Assessment of Cancer Therapy - Colorectal (FACT-C), SF-36 version 2, European Organization for Research and Treatment of Cancer QLQ-C30, and Brief Pain Inventory assessments from these studies were reviewed. RESULTS Seven studies reporting on 382 patients were included. Baseline QoL was the strongest predictor of postoperative QoL. Female gender, total pelvic exenteration with or without bone resection, and positive surgical margins were associated with a reduced QoL. In the majority of patients, QoL gradually improved between 2 and 9 months post-operation. CONCLUSION QoL is an important patient-reported outcome. This review highlights factors associated with reduced postoperative QoL that should be borne in mind when surgical resection is being considered.

Abstract
Purpose Sphincter-preserving operations performed with bladder-preserving surgery and a cystourethral anastomosis (CUA) do not require a urinary stoma, but leakage from the CUA may develop. The aim of this study was to evaluate the efficacy of performing an additional flap operation. Methods The subjects were 39 patients who underwent bladder-preserving surgery for advanced rectal cancer involving the prostate, between 2001 and 2015.32 of whom had a CUA and one of whom had a neobladder. Five of these 32 patients underwent an ileal flap operation, 2 underwent an omental flap operation, and 3 underwent an operation using both flaps. Results Leakage developed in 3 (30%) of the 10 patients who underwent additional flap operations, but in 14 (60.9%) of the 23 patients who did not undergo a flap operation. The mean periods of catheterization for the patients who suffered leakage were 31 weeks (8–108 weeks) in those without a flap and 16 weeks (8–20 weeks) in those with a flap. Four (33.3%) of the 12 patients with leakage after surgery without a flap had a period of urinary catheterization >30 weeks, and 2 (16.7%) had leakage of CTCAE grade 3. There were no cases of leakage after flap surgery. Conclusion An additional flap operation may decrease the risk of leakage from a CUA.

Abstract
BACKGROUND Locally advanced pelvic malignancy can be associated with disabling symptoms and reduced quality of life. If resectable with clear margins, a pelvic exenteration can offer long-term survival and improved quality of life. Its role in the palliation of symptoms has been described; however, the clinical outcomes and surgical indication are poorly defined. OBJECTIVE This study describes the clinical and quality-of-life outcomes after palliative pelvic exenteration for advanced pelvic malignancy. DESIGN Clinical data and patient-reported outcomes were collected for patients undergoing pelvic exenteration for symptom palliation. SETTINGS This study was conducted at a tertiary referral center for pelvic exenteration. PATIENTS All of the patients undergoing palliative pelvic exenteration for advanced primary rectal or recurrent cancer were included in our analysis. MAIN OUTCOME MEASURES Patient-reported quality of life and physical and mental health status were measured. Quality-of-life trajectories were modeled over the 12 months from the date of surgery using linear mixed models. RESULTS A total of 39 patients underwent pelvic exenteration for symptom palliation. Although there were no in-hospital deaths, 34% experienced significant morbidity. Patient-reported quality of life reduced postoperatively and gradually declined thereafter. Overall median survival was 24 months, with a 1-year mortality rate of 31%. There was a significant survival difference for the 39 patients undergoing pelvic exenteration compared with those patients who only had a debulking/bypass procedure or were closed without definitive treatment (overall median survival = 24 versus 9 months; p = <0.02). LIMITATIONS Disease and patient heterogeneity limit the interpretation of these results. CONCLUSIONS Palliative pelvic exenteration is a technically demanding operation that can be performed safely in a dedicated exenteration center. However, no durable palliation of symptoms with associated improved or sustained quality of life was observed, and the role of palliation therefore remains highly controversial in this complex group of patients.

Abstract
BACKGROUND Locally advanced rectal cancers (LARCs) involve one or more of the adjacent organs in upto 10-20% patients. The cause of the adhesions may be inflammatory or neoplastic, and the exact causes cannot be determined pre- or intra-operatively. To achieve complete resection, partial or total mesorectal excision (TME) en bloc with the involved organs is essential. The primary objective of this study is to determine short-term oncological and clinical outcomes in these patients undergoing multivisceral resections (MVRs). METHODS This is a retrospective review of a prospectively maintained database. Between 1 July 2013 and 31 May 2015, all patients undergoing MVRs for adenocarcinoma of the rectum were identified from this database. All patients who had en bloc resection of an adjacent organ or part of an adjacent organ were included. Those with unresectable metastatic disease after neoadjuvant therapy were excluded. RESULTS Fifty-four patients were included in the study. Median age of the patients was 43 years. Mucinous histology was detected in 29.6% patients, and signet ring cell adenocarcinoma was found in 24.1% patients. Neoadjuvant therapy was given in 83.4% patients. R0 resection was achieved in 87% patients. Five-year overall survival (OS) was 70% for the entire cohort of population. CONCLUSIONS In Indian subcontinent, MVRs in young patients with high proportion of signet ring cell adenocarcinomas based on magnetic resonance imaging (MRI) of response assessment (MRI 2) is associated with similar circumferential resection margin (CRM) involvement and similar adjacent organ involvement as the western patients who are older and surgery is being planned on MRI 1 (baseline pelvis). However, longer follow-up is needed to confirm noninferiority of oncological outcomes.

Abstract
The liver-first approach was proposed for the first time in 2006 to obtain resectability of stage IV colorectal cancer patients and complete the therapeutic plan. From then some groups have used this new revolutionary approach reporting promising results. Other alternative strategies have been proposed for metastatic patients. The authors reviewed the literature weighing the pros and cons of each strategy proposed to manage these advanced tumor stages. The therapeutic options are analyzed in the light of oncologic problems and evidence. Also problems, questions and perspectives are given. Even if the 'liver-first' approach seems to be a promising strategy, the ideal diagnostic-therapeutic flowchart for metastatic colorectal cancer is still difficult to standardize. The great heterogeneity of this population of patients is one of the main problems. A 'tailored approach' philosophy is necessary to calibrate, in a multidisciplinary setting, a case-by-case choice of therapeutic options.

Abstract
PURPOSE The clinical outcomes of patients who have undergone total pelvic exenteration (TPE) for locally advanced primary colorectal cancer have not been satisfactory. For the last 13 years, we have performed layer-oriented, en bloc resection of tumor for which TPE is indicated, in the hope of improving postoperative outcomes. The clinical outcomes of these cases were retrospectively analyzed. METHODS A total of 54 patients who underwent TPE from 1986 to 2013 were retrospectively analyzed. Since 2002, a layer-oriented removal for clinical T4 colorectal cancer, as in T3 or less invasive tumors removed by total mesorectal excision, was applied to 23 cases for which TPE was indicated. Postoperative mortality, morbidity, overall survival (OS), and disease-free survival (DFS) were evaluated. RESULTS On univariate analysis, good postoperative OS and DFS were associated with the layer-oriented operative maneuver, blood loss less than 2000 mL, negative nodal metastasis, and no preoperative radiation therapy. Male sex was the marginal determinant correlated with good OS and DFS. Depth of invasion to T3 was the marginal determinant correlated with good DFS. On multivariate analysis using the 4 factors identified on univariate analyses, the layer-oriented operative procedure was a significant determinant for both good OS and DFS, together with negative nodal metastases. Postoperative mortality and morbidity in the layer-oriented excision were acceptable. CONCLUSION For primary colorectal cancers for which TPE is indicated, layer-oriented excision was a safe and effective procedure, and it may be recommended as one of the standard surgical approaches in TPE.

Abstract
PURPOSE The present study aimed to assess the safety and feasibility of laparoscopic extended pelvic surgery for primary or recurrent rectal cancer. METHODS The data on 77 patients, who underwent extended pelvic surgery between February 2008 and June 2014, were retrospectively analyzed. The patients were divided, based on their treatment history, into an open surgery (OS) group (n = 41) and a laparoscopic surgery (LS) group (n = 36). RESULTS The operative time in the LS group was significantly longer than that in the OS group (766 vs. 561 min; p < 0.001). In contrast, the LS group was associated with a significantly lower volume of intraoperative blood loss (195 vs. 923 ml; p < 0.001), fluid balance (5.38 vs. 8.23 ml/kg/h; p < 0.001) and rate of complications (40.0 vs. 68.3 %; p = 0.035), and a significantly shorter postoperative hospital stay. The postoperative levels of colloid osmotic pressure and albumin were significantly higher in the LS group. CONCLUSION The operative time of the LS group was longer than that of the OS group; however, the LS group experienced less blood loss and fewer complications. Moreover, LS was associated with a reduction in intraoperative infusions and a reduced fluid balance, which maintained homeostasis.

Abstract
BACKGROUND Previous reports about laparoscopic total pelvic exenteration (LTPE) are still limited. In the present study, we described our single-center experience of the initial 11 cases. METHODS Between April 2011 and September 2015, eight males and three females diagnosed as pelvic malignancies underwent LTPE by the same operation team. We retrospectively collected all cases' parameters about surgical technique. Thirty-seven patients who received open surgery were also retrospectively collected. A comparison between LTPE and open surgery was performed to evaluate the feasibility and safety of LTPE. RESULTS Eleven cases successfully underwent the LTPE without any intraoperative complication. No open conversion was required. Eight patients underwent Bricker's procedure. Three patients were performed with the cutaneous ureterostomy. Anus preservation operation was performed in three patients. Compared with open surgery, LTPE had longer mean operative time (565.2 vs 468.2 min, p = 0.004) but less mean blood loss (547.3 vs 1033.0 ml, p < 0.001) and shorter postoperative hospitalization time (15.3 vs 22.4 days, p = 0.004). One patient died of pulmonary embolism in the 7th month of follow-up time. One patient died of recurrence in the 12th month of follow-up time. Nine patients are still alive without recurrence and metastasis. The mean follow-up time was 11.1 months. CONCLUSIONS The technique of LTPE seems to be feasible and safe in the treatment of carefully selected patients of pelvic malignancies. LTPE can also decrease the blood loss, the recovery time, and the hospital stay. But the oncological safety and long-term outcome of LTPE still need to be explored.

Abstract
PURPOSE The objective of this study was to assess the clinical outcomes of pelvic exenteration for patients with primary locally advanced colorectal cancer (LACRC) or locally recurrent colorectal cancer (LRCRC), and to identify clinically relevant prognostic factors. METHODS Between January 2001 and December 2010, 40 consecutive patients with primary LACRC or LRCRC underwent pelvic exenteration at the National Cancer Center, Republic of Korea. We retrospectively reviewed their medical records. RESULTS The median age was 59 years and the median follow-up time was 26 months (range, 1-117 months). The overall complication and in-hospital mortality rates were 70% (28/40) and 7.5% (3/40), respectively. The complication rates were similar between patients with primary LACRC (69.6%) and those with LRCRC (70.6%). The overall recurrence rate was 50% (17/34), and was lower in patients with primary LACRC than in patients with LRCRC (33.3% vs. 76.9%, P = 0.032). The 5-year overall survival was significantly different between primary LACRC and patients with LRCRC (58.7% vs. 11.8%, P = 0.022). Multivariate analysis revealed that radicality (R0 vs. R1/R2) was an independent prognostic factor for overall survival (P = 0.020). CONCLUSION The complication and operative mortality rates of pelvic exenteration remained high, but pelvic exenteration might provide an opportunity for long-term survival and good local control. Complete (R0) resection was the only independent prognostic factor for overall survival.

Abstract
BACKGROUND Determining predictors of surgical site infection (SSI) in a large cohort is important for the design of accurate SSI surveillance programs. We hypothesized that additional organ resection and pelvic exenterative procedures are associated independently with a higher risk of SSI. METHODS Patients in the American College of Surgeons National Surgical Quality Improvement Program® (ACS NSQIP®; American College of Surgeons, Chicago, IL) database (2005-2012) were identified (n=112,282). Surgical site infection (superficial or deep SSI) at 30 d was the primary outcome. Using primary and secondary CPT® codes (American Medical Association, Chicago, IL) pelvic exenteration was defined and additional organ resection was defined as: bladder resection/repair, hysterectomy, partial vaginectomy, additional segmental colectomy, small bowel, gastric, or diaphragm resection. Univariable analysis of patient and procedure factors identified significant (p<0.05) predictors, which were modeled using stepwise logistic regression. RESULTS The rate of SSI was 9.2%. After adjusting for operative duration, predictors of SSI were body mass index (BMI) 25-29.9 (odds ratio [OR]: 1.3), BMI 30-34.9 (OR: 1.59), BMI 35-39.9 (OR: 2.11), BMI>40 (OR: 2.51), pulmonary comorbidities (OR: 1.22), smoking (OR: 1.24), bowel obstruction (OR: 1.40), wound classification 3 or 4 (OR: 1.18), and abdominoperineal resection (OR: 1.58). Laparoscopic or laparoscopically assisted procedures offered a protective effect against incision infection (OR: 0.55). Additional organ resection (OR: 1.08) was also associated independently with SSI, but the magnitude of the effect was decreased after accounting for operative duration. In the analysis that excludes operative duration, pelvic exenteration is associated with SSI (OR: 1.38), but incorporating operative duration into the model results in this variable becoming non-significant. CONCLUSIONS In addition to other factors, obesity, surgery for bowel obstruction, abdominoperineal resection, and additional organ resection are independently associated with a higher risk of SSI. Surgical site infection risk in pelvic exenteration and multiple organ resection cases appears to be mediated by prolonged operative duration. In these established high-risk sub-groups of patients, aggressive interventions to prevent SSI should be implemented.

Abstract
BACKGROUND The importance of the circumferential resection margin has been demonstrated in primary rectal cancer, but the role of the minimal tumor-free resection margin in locally recurrent rectal cancer is unknown. OBJECTIVE The purpose of this work was to evaluate the prognostic importance of a minimal tumor-free resection margin in locally recurrent rectal cancer. DESIGN This was a single-institution, retrospective study. SETTINGS This study was conducted in a tertiary referral hospital. PATIENTS Based on the final pathology report, surgically treated patients with locally recurrent rectal cancer between 1990 and 2013 were divided into 4 groups: 1) tumor-free margins of >2 mm, 2) tumor-free margins of >0 to 2 mm, 3) microscopically involved margins, and 4) macroscopically involved margins. MAIN OUTCOME MEASURES Local control and overall survival were the main outcome measures. RESULTS A total of 174 patients with a median follow-up of 27 months (range, 0-144 months) were eligible for analysis. There was a significant difference in 5-year local re-recurrence-free survival in favor of 41 patients with tumor-free margins of >2 mm compared with 34 patients with tumor-free margins of >0 to 2 mm (80% vs 62%; p = 0.03) and a significant difference in 5-year overall survival (60% vs 37%; p = 0.01). The 5-year local re-recurrence-free and overall survival rates for 55 patients with microscopically involved margins were 28% and 16%, and for 20 patients with macroscopically involved margins the rates were 0% and 5%. On multivariable analysis, tumor-free margins of >0 to 2 mm were independently associated with higher re-recurrence rates (HR, 2.76 (95% CI, 1.06-7.16)) and poorer overall survival (HR, 2.57 (95% CI, 1.27-5.21)) compared with tumor-free margins of >2 mm. LIMITATIONS This study was limited by its retrospective nature. CONCLUSIONS Resection margin status is an independent prognostic factor for re-recurrence rate and overall survival in surgically treated, locally recurrent rectal cancer. In complete resections, patients with tumor-free resection margins of >0 to 2 mm have a higher re-recurrence rate and a poorer overall survival than patients with tumor-free resection margins of >2 mm.

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

Abstract
BACKGROUND Generalization of laparoscopic pelvic surgery has brought about profound knowledge of the pelvic anatomy and has encouraged expansion of indications for laparoscopic surgery to extended pelvic surgery. Pelvic exenteration (PE) is still a demanding surgical procedure and remains an essential technique for pelvic surgery although minimally invasive and function-preserving surgery is in the mainstream of surgical treatment. However, the techniques of laparoscopic PE (LPE) have been rarely explained nor has its feasibility been fully evaluated. The aim of this study was to describe important technical points and to assess the feasibility of LPE for pelvic malignancies. METHODS Data on 67 patients with pelvic malignancies, who underwent PE between June 2006 and August 2014, were analyzed retrospectively. LPE has been indicated since 2013. Patients were divided into the LPE group (n = 9) and the conventional open PE (OPE) group (n = 58). RESULTS Operative time in the LPE and OPE groups was similar (935 vs. 883 min, p = 0.398). Intraoperative blood loss in the LPE group was significantly less than that in the OPE group (830 vs. 2769 ml, p = 0.003). Pathological R0 resection rate was similar in both groups (77.8 vs. 75.9%). Overall incidence of any complication and major complications were much lower in the LPE group (66.7 and 0%) compared to the OPE group (89.7 and 32.8%), although not statistically significant (p = 0.094 and 0.053, respectively). Postoperative hospital stay was significantly shorter in the LPE group than in the OPE group (27 vs. 43 days, p = 0.003). CONCLUSIONS We confirmed that LPE for pelvic malignancies resulted in less blood loss, a lower complication rate, and shorter postoperative hospital stay compared to OPE. LPE performed by an experienced pelvic surgeon was safe and efficient, and might be a promising option for carefully selected patients.

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

Abstract
Study Design Case report. Objective The usual procedure for partial sacrectomies in locally advanced rectal cancer combines a transabdominal and a posterior sacral route. The posterior approach is flawed with a high rate of complications, especially infections and wound-healing problems. Anterior-only approaches have indirectly been mentioned within long series of rectal cancer surgery. We describe a case of partial sacrectomy for en bloc resection of a locally advanced rectal cancer with invasion of the low sacrum through a combined transabdominal and perineal approach without any posterior incision. Methods Through a midline laparotomy, the tumor was dissected and the sacral osteotomy was performed. Once the sacrum was mobile, the muscular attachments to its posterior wall were cut through the perineal approach. This latter route was also used to remove the whole specimen. Results The postoperative period was uneventful in terms of infection and wound healing, but the patient developed right foot dorsiflexion paresis that completely disappeared in 1 month. Resection margins were negative. After a follow-up of 18 months, the patient has no local recurrence but presented lung and liver metastases. Conclusion In cases of rectal cancer involving the low sacrum, the combination of a transabdominal and a perineal route to carry out the partial sacrectomy is a feasible approach that avoids changes of surgical positioning and the morbidity related to posterior incisions. This strategy should be considered when deciding on undertaking partial sacrectomy in locally advanced rectal cancer.

Abstract
BACKGROUND There is minimal published data evaluating the oncological outcome of rectal resection with prostatectomy alone versus rectal resection with cystoprostatectomy in patients undergoing pelvic exenteration for locally advanced or recurrent pelvic cancer. This study aims to evaluate the oncological and functional outcomes of performing rectal resection with prostatectomy alone compared with rectal resection with cystoprostatectomy in patients undergoing pelvic exenteration. METHODS Consecutive patients undergoing pelvic exenteration for locally advanced or recurrent pelvic cancer between 1998 and 2012 were identified from a prospectively maintained database. Patients undergoing rectal resection with prostatectomy alone were compared with a control group who underwent rectal resection with cystoprostatectomy and urostomy formation. The primary outcome was overall survival. Secondary outcomes analysed in the prostatectomy group included completeness of resection, continence and erectile function. RESULTS Eleven rectal resections with prostatectomy were compared with 20 rectal resections with cystoprostatectomy. R0 resection was achieved in 73 and 65% respectively. There was no difference in overall survival (P = 0.40). Urinary continence was achieved in 36% of prostatectomy alone patients, while 27% experienced mild incontinence. Erectile function was poor, with only one patient able to maintain normal erections. CONCLUSION In appropriately selected patients with invasive pelvic tumours, rectal resection with prostatectomy alone provides adequate oncological outcomes. The ability to achieve an R0 resection was not compromised and overall survival is comparable with cystoprostatectomy. Urinary function is reasonable in most patients, although sexual function is compromised in almost all.
