Abstract
Multimodal treatment approaches with neoadjuvant radiotherapy and chemotherapy followed by oncological and total mesorectal excision (TME) have significantly reduced the recurrence rate even in locally advanced rectal cancer. Nevertheless, up to 10% of patients develop a local relapse. Surgical R0 resection is the only chance of a cure in the treatment of locally recurrent rectal cancer (LRRC). Due to the altered anatomy and physiology of the true pelvis as a result of the pretreatment and operations as well as the localization and extent of the recurrence, the treatment decision is individualized and remains a challenge for the interdisciplinary team. Even locally advanced tumors with involvement of adjacent structures can be treated in designated centers using multimodal treatment concepts with potentially curative intent.

Abstract
Pelvic exenteration (PE) is a technically challenging surgical procedure. More recently, quality of life and survivorship following PEs are being increasingly acknowledged as important patient outcomes. This includes evaluating major long-term complications such as hernias, defined as the protrusion of internal organs through a facial defect (The PelvEx Collaborative in Br J Surg 109:1251-1263, 2022), for which there is currently limited literature. The aim of this paper is to ascertain the incidence and risk factors for postoperative hernia formation among our PE cohort managed at a quaternary centre. METHOD A retrospective cohort study examining hernia formation following PE for locally advanced rectal carcinoma and locally recurrent rectal carcinoma between June 2010 and August 2022 at a quaternary cancer centre was performed. Baseline data evaluating patient characteristics, surgical techniques and outcomes was collated among a PE cohort of 243 patients. Postoperative hernia incidence was evaluated via independent radiological screening and clinical examination. RESULTS A total of 79 patients (32.5%) were identified as having developed a hernia. Expectantly, those undergoing flap reconstruction had a lower incidence of postoperative hernias. Of the 79 patients who developed postoperative hernias, 16.5% reported symptoms with the most common symptom reported being pain. Reintervention was required in 18 patients (23%), all of which were operative. CONCLUSION This study found over one-third of PE patients developed a hernia postoperatively. This paper highlights the importance of careful perioperative planning and optimization of patients to minimize morbidity.

Abstract
ABSTRACT Intravascular invasion of tumor cells can be associated with metastasis in many cancers. Basal cell carcinomas (BCCs), however, rarely metastasize; therefore, the clinical impact of intravascularly invasive BCC (IVBCC) is currently unclear. Because of these facts and the rarity of IVBCC, questions have arisen on whether IVBCC truly exists. We present 4 cases of IVBCC: one case with obvious tumor islands within immunolabeled blood vessels in the context of advanced disease and 3 cases found incidentally during Mohs micrographic surgery. We discuss the difficulty in studying IVBCC, the idea that it could be due to artifact, and the lack of direct clinical-pathological correlation. Given these challenges, we propose diagnostic criteria for IVBCC to decrease ambiguity for pathological diagnosis. Such criteria may facilitate further studies on the clinical significance of IVBCC.

Abstract
Guanylyl cyclase C (GCC) is a transmembrane surface receptor restricted to intestinal epithelial cells, from the duodenum to the rectum. We compared GCC expression in tumors and normal rectal tissues, and investigated the relation between GCC expression and metastasis and long-term survival of rectal cancer patients. Based on the UICC classification, 42 rectal cancer patients in this study were classified as stage I, 48 patients as stage II, and 90 patients as stage III. Overexpression of GCC was observed in 80 rectal tumors as compared to matched normal tissues, where no strong staining of GCC was observed. An association between GCC mRNA in the circulation and tumor emboli in vessels, CK20 mRNA, distant organ metastasis, and survival status was observed in 100 rectal cancer patients. Univariate Cox regression analysis indicated that tumor emboli in vessels, lymph node metastasis, mesenteric root lymph node metastasis and GCC mRNA correlated with 5-year disease-free survival (DFS); while lymph node metastasis, GCC mRNA, and CK20 mRNA strongly correlated with 5-year overall survival (OS). In a multivariate Cox regression model, GCC mRNA level and mesenteric root lymph node metastasis associated with DFS, while GCC mRNA levels associated with OS. Quantification of GCC expression in circulation is a valuable biomarker for assessing tumor burden and predicting outcome in rectal cancer patients.

Abstract
BACKGROUND Pelvic exenteration for locally recurrent rectal cancer (LRRC) is associated with variable outcomes, with the majority of data from single-centre series. This study analysed data from an international collaboration to determine robust parameters that could inform clinical decision-making. METHODS Anonymized data on patients who had pelvic exenteration for LRRC between 2004 and 2014 were accrued from 27 specialist centres. The primary endpoint was survival. The impact of resection margin, bone resection, node status and use of neoadjuvant therapy (before exenteration) was assessed. RESULTS Of 1184 patients, 614 (51·9 per cent) had neoadjuvant therapy. A clear resection margin (R0 resection) was achieved in 55·4 per cent of operations. Twenty-one patients (1·8 per cent) died within 30 days and 380 (32·1 per cent) experienced a major complication. Median overall survival was 36 months following R0 resection, 27 months after R1 resection and 16 months following R2 resection (P < 0·001). Patients who received neoadjuvant therapy had more postoperative complications (unadjusted odds ratio (OR) 1·53), readmissions (unadjusted OR 2·33) and radiological reinterventions (unadjusted OR 2·12). Three-year survival rates were 48·1 per cent, 33·9 per cent and 15 per cent respectively. Bone resection (when required) was associated with a longer median survival (36 versus 29 months; P < 0·001). Node-positive patients had a shorter median overall survival than those with node-negative disease (22 versus 29 months respectively). Multivariable analysis identified margin status and bone resection as significant determinants of long-term survival. CONCLUSION Negative margins and bone resection (where needed) were identified as the most important factors influencing overall survival. Neoadjuvant therapy before pelvic exenteration did not affect survival, but was associated with higher rates of readmission, complications and radiological reintervention.

Abstract
OBJECTIVE This study aimed to visually and quantitatively compare (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) imaging in determining postoperative pelvic recurrence in colorectal cancer (CRC). MATERIALS AND METHODS This retrospective analysis focused on 96 patients (age: mean 62.6 ± 10.5) with surgically resected CRC (time interval after surgery: 19.2 ± 20.4 months). The standard of reference was histopathologic confirmation (n = 27) or imaging follow-up (n = 69). For visual analysis, three independent nuclear physicians interpreted the PET/CT findings. For the quantitative analysis, the normalized standardized uptake values (nSUVs: nSUVmax, nSUVpeak, nSUVmean) were calculated by applying the mean SUV of a normal liver. We evaluated the areas under the receiver operating characteristic curves (AUCs) for all the quantitative parameters. RESULTS Of the 96 patients, 49 showed pelvic recurrence and 47 revealed no tumor recurrence. Sensitivity and specificity were 85.7 and 80.9 %, respectively, for visual analysis, and 65.3 and 83.0 %, respectively, for quantitative analysis. The AUC (0.766, CI: 0.668-0.846) of nSUVmax was largest comparing nSUVpeak and nSUVmean values, without significant difference (p value >0.316). Sensitivity of lesion detection was superior in visual analysis (p value = 0.02), but specificity was not significantly different (p = 0.80). After inclusive and exclusive combinations, sensitivity and specificity were slightly increased to 89.8 % (p = 0.54) and 91.5 % (p = 0.14), respectively. CONCLUSIONS Visual interpretation was superior to quantitative analysis in pelvic tumor recurrence in CRC. Though it was possible to improve diagnostic performance through combinatory analysis, the effect was not statistically significant.

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

Abstract
BACKGROUND Complete pathological resection of locally advanced or recurrent rectal and anal cancer is regarded as one of the most important determinants of oncological outcome. Disease in the lateral pelvic sidewall has been considered a contraindication for pelvic exenteration surgery owing to the significant likelihood of incomplete resection. METHODS We describe a novel technique (ELSiE) to resect disease involving the lateral pelvic sidewall. Patient demographics, post-operative histology, length of hospital stay and complications were collected from prospectively maintained electronic patient database. RESULTS During 2011-2013, six patients underwent pelvic exenteration surgery with the ELSiE approach. All patients had R0 resection. Three patients required sciatic nerve excision. Four patients developed post-operative complications although no major complications occurred. CONCLUSIONS Patients with locally advanced and recurrent cancer involving the lateral pelvic sidewall may be rendered suitable for potentially curative radical resection with a modification in the approach to the lateral pelvic sidewall. Our pilot series seems to indicate that our novel technique (ELSiE) is feasible, safe and yields high rates of complete pathological resection.

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

Abstract
Although the incidence of local recurrence after curative resection of rectal cancer has decreased due to the understanding of the anatomy of pelvic structures and the adoption of total mesorectal excision, local recurrence in the pelvis still remains a significant and troublesome complication. While surgery for recurrent rectal cancer may offer a chance for a cure, conservative management, including radiation and chemotherapy, remain widely accepted courses of treatment. Recent improvement in imaging modalities, perioperative care, and surgical techniques, including bone resection and wound coverage, have allowed for reductions in operative mortality, though postoperative morbidity still remains high. In this review, the techniques, including surgical approaches, employed for management of locally recurrent rectal cancer are highlighted.

Abstract
AIMS Intraoperative radiotherapy (IORT) for locally advanced rectal cancer as an integral part of multimodal treatment, may lead to reduced local recurrence but it is not routinely used. The aim of this paper is to describe our experience with IORT in the treatment of patients with locally advanced adenocarcinoma of the lower third of the rectum. MATERIAL AND METHODS Laparoscopic abdominoperineal amputation of the rectum with intraoperative radiotherapy was performed on 17 patients, 13 men and 4 women, median age 64 years (49-75 years) between 2010-2011. All patients underwent complete therapy according to the treatment protocol. RESULTS In one patient, the laparoscopic procedure had to be converted to an open resection. The duration of the surgical procedure with IORT was 185 to 345 min (median 285 min). In 14 cases, the intraoperative dose was 10 Gy and in two patients a dose of 12 Gy was used. There were no severe intraoperative complications. Blood loss ranged from 30 to 500 mL (median 100 mL). There were postoperative complications in 4 patients (23.5%); 2 necessitated surgical reintervention (11.8%). The duration of postoperative hospitalization was 6 to 35 days (median 7 days). In the follow-up of 2 to 16 months (median 12 months), no local recurrence or disease generalization have been found to date. CONCLUSIONS The results show the technical feasibility of laparoscopically assisted abdominoperineal amputation of the rectum in combination with IORT in the treatment of locally advanced rectal carcinoma with an acceptable risk of postperative complications.

Abstract
OBJECTIVE Management options for colorectal cancer have expanded in recent years. We estimated average lifetime cost of care for colorectal cancer in Ireland in 2008, from the health care payer perspective. METHOD A decision tree model was developed in Microsoft EXCEL. Site and stage-specific treatment pathways were constructed from guidelines and validated by expert clinical opinion. Health care resource use associated with diagnosis, treatment and follow-up were obtained from the National Cancer Registry Ireland (n=1,498 cancers diagnosed during 2004-2005) and three local hospital databases (n=155, 142 and 46 cases diagnosed in 2007). Unit costs for hospitalisation, procedures, laboratory tests and radiotherapy were derived from DRG costs, hospital finance departments, clinical opinion and literature review. Chemotherapy costs were estimated from local hospital protocols, pharmacy departments and clinical opinion. Uncertainty was explored using one-way and probabilistic sensitivity analysis. RESULTS In 2008, the average (stage weighted) lifetime cost of managing a case of colorectal cancer was €39,607. Average costs were 16% higher for rectal (€43,502) than colon cancer (€37,417). Stage I disease was the least costly (€23,688) and stage III most costly (€48,835). Diagnostic work-up and follow-up investigations accounted for 4 and 5% of total costs, respectively. Cost estimates were most sensitive to recurrence rates and prescribing of biological agents. CONCLUSION This study demonstrates the value of using existing data from national and local databases in contributing to estimating the cost of managing cancer. The findings illustrate the impact of biological agents on costs of cancer care and the potential of strategies promoting earlier diagnosis to reduce health care resource utilisation and care costs.

Abstract
AIM Abdominoperineal resection for rectal cancer is associated with higher rates of local recurrence and poorer survival than anterior resection. The aim of this study was to evaluate the outcome of conventional abdominoperineal resection in a large national series. METHOD The study was based on the Danish National Colorectal Cancer Database and included patients treated with abdominoperineal resection between 1 May 2001 and 31 December 2006. Follow up in the departments was supplemented with vital status in the Civil Registration System. The analysis included actuarial local and distant recurrence, and overall and cancer-specific survival. Risk factors for local recurrence, distant metastases, overall survival and cancer-specific survival were identified using multivariate analyses. RESULTS A total of 1125 patients were followed up for a median of 57 (25-93) months. Intra-operative perforation was reported in 108 (10%) patients. The cumulative 5-year local recurrence rate was 11% [95% confidence interval (CI), 7-13)], overall survival was 56% (95% CI, 53-60) and cancer-specific survival was 68% (95% CI, 65-71). Multivariate analysis showed that perforation, tumour stage and nonradical surgery were independent risk factors for local recurrence; tumour fixation to other organs, perforation and tumour stage were independent risk factors for distant metastases; and risk factors for impaired overall survival and cancer-specific survival were age, tumour perforation, tumour stage, lymph node metastases and nonradical surgery. CONCLUSION Intra-operative perforation is a major risk factor for local and distant recurrence and survival and therefore should be avoided.

Abstract
Radical resection is the only potential cure for patients with locally advanced primary and recurrent rectal cancer and is considered curative only when the histologic margins are clear of tumour. Early diagnosis of the disease is essential as it increases the likelihood of a potentially curative resection and prevention of dissemination. Clinical examination, tumour markers and radiologic modalities such as ultrasonography, computed tomography, magnetic resonance imaging and positron emission tomography are routinely used in an effort to accurately stage these patients and provide useful information for the selection of patients for further treatment/management. This review describes the methods of staging patients with locally advanced primary and recurrent rectal cancer prior to surgery emphasizing the role that radiologists have in this process.

Abstract
Colorectal cancer (CRC) is a major cause of cancer-related morbidity and mortality. Molecular imaging using positron emission tomography (PET) is now an integral part of multidisciplinary cancer care. In this review, we discuss the role of PET in CRC including well established indications in the assessment of recurrent disease and emerging applications such as initial staging, monitoring therapy efficacy and using PET for radiotherapy planning. With rapid advancement in imaging technology, we also discuss the future potential of combining PET and magnetic resonance imaging and the use of novel radiotracers.

Abstract
AIM A systematic review of the literature with meta-analysis was performed to evaluate the time to locoregional recurrence after curative resection of rectal carcinoma, assuming that this time is prolonged after neoadjuvant radiochemotherapy and/or present day surgery. METHOD English and German language peer-reviewed articles published between 1980 and 2007 were selected. Twenty-five of 118 studies fulfilled the defined inclusion and exclusion criteria. For some special questions, data of the Erlangen Registry of Colorectal Carcinoma (ERCRC) from 1985 to 1997 are reported. RESULTS After conventional surgery of rectal carcinoma, 75% (range 66-84%) of locoregional recurrence presented during the first 2 years after resection. Following the introduction of total mesorectal excision surgery and the use of neoadjuvant treatment, a general reduction of the frequency of local recurrence combined with a prolongation of the time to local recurrence was observed. In the practice of today, in particular after neoadjuvant long-course radiochemo-or radiotherapy, 24% (range 8-40%) of all local recurrences present later than 5 years after primary therapy. In contrast, such late local recurrences are observed in only 8% (range 5-9%) following primary surgery alone. CONCLUSION For a definite assessment of the therapeutic results regarding local control, a minimal follow up of 7-8 years either after neoadjuvant long-course radiochemo- or radiotherapy and a minimum of 5 years after surgery alone is necessary. For patients with primary surgery followed by adjuvant therapy, it is not possible to make a clear statement.

Abstract
BACKGROUND The influence of surgical principles and neoadjuvant therapy on the frequency of local tumor cell dissemination (LTCD) in rectal carcinoma surgery and its consequences for local recurrence and survival rates were analyzed. PATIENTS AND METHODS Data from the Erlangen registry for colorectal carcinomas (ERCRC) from 1969-2008 were compared with data from the literature published in 1980-2008. RESULTS LTCD was observed in 6.7% in the ERCRC (n=2764) and a frequency of 6.9% was reported in in the literature (n=13,395). In the course of time and especially since the introduction of total mesorectal excision (TME) surgery, the incidence of LTCD has significantly decreased. Neoadjuvant treatment did not influence the frequency of LTCD. Following LTCD the rate of local recurrence significantly increased and the 5 year survival rate significantly decreased. This also applied to patients with neoadjuvant therapy. CONCLUSIONS Even in the era of TME surgery attention must to be paid to avoidance of LTCD. It is obligatory to document the occurrence of LTCD and it must be taken into consideration in routine quality assurance. In cases of LTCD postoperative chemoradiation is indicated for patients without neoadjuvant irradiation.

Abstract
Abdominoperineal resection (APR) remains the standard procedure for rectal cancer located within 0.5 cm from dentate line (DL). In this study, we present a new type of restorative surgery: intersphincteric resection with partial removal of external anal sphincter (EAS) and anorectal reconstruction for-ultra low rectal cancer. Between March 2003 and May 2008 fifty patients (28 males, aged between 39 and 71) were operated on for ultra low rectal cancer uT2-3N0M0 with partial preservation of EAS and total anorectal reconstruction (smooth-muscle neosphincter and colonic pouch). A protective stoma was performed in all cases. Functional outcome and quality of life were recorded at 3, 6, 12, 18, 24 months after stoma closure using Wexner score and FIQL respectively. Anal manometry, vectrum volumetry and myography data were taken as well. Results. Postoperative complications developed in 2 patients, but no secondary surgery was required. Carcinomas were staged as pT2 (n = 14) and pT3 (n = 36). The distal clearance was 2.00.4 (range 1.5-2.8) cm, lateral clearance was 0.80.3 (range 0.2-1.4) cm. After a median follow-up of 24 (range 2-61) months, 2 local recurrences were occurred and salvaged by APR. Contractive activity of saved elements of EAS improved with a course of time and squeezing anal pressure increased as well. Perfect functional outcome was achieved in 25 of 34 patients at 12 months after stoma closure, and all the patients were satisfied with procedure. Good functional results of suggested surgery seems to be an acceptable alternative to APR with permanent stoma in selected patients.

Abstract
PURPOSE 18-Fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) has a role in recurrent colorectal cancer. This study was designed to assess the impact of PET-CT on management of primary rectal cancer. METHODS Eighty-three patients with rectal cancer underwent PET-CT scan between 2002 and 2005. Referring physicians prospectively recorded stage and management plan after conventional imaging before PET-CT scan, which were compared to subsequent stage and management after PET-CT. RESULTS Staging PET-CT caused a change in stage from conventional imaging in 26 patients (31 percent). Twelve (14 percent) were upstaged (7 change in N stage; 4 change in M stage; 1 change in N and M stage), and 14 (17 percent) were downstaged (10 change in N stage; 3 change in M stage; 1 change in N and M stage). PET-CT scan altered management intent in seven patients (8 percent) (curative to palliative 6 patients; palliative to curative 1 patient). Management was altered in ten patients (12 percent). There was no difference in impact with respect to tumor height. CONCLUSIONS PET-CT scan impacts the management of patients with primary rectal cancer and influences staging/therapy in a third of patients and should be a component of rectal cancer workup.

Abstract
PURPOSE Surgery for recurrent rectal cancer is the only therapy with curative potential. This study was designed to assess factors that affect survival after surgery for locally recurrent rectal cancer. METHODS Prospective databases of patients undergoing surgical resection for recurrent rectal cancer at three tertiary centers between 1990 and 2006 were combined and analyzed. Cox regression and Kaplan-Meier survival analysis were used to assess factors associated with survival. RESULTS A total of 160 patients (96 males) underwent surgery (median age, 63 (range, 27-93) years). Ninety-five patients (59 percent) received neoadjuvant radiotherapy. Sixty-three patients (39 percent) underwent radical resection and 90 (56 percent) underwent extended radical resection. Seven patients (5 percent) were irresectable. There was one death and 27 percent had major postoperative complications, independent of extent of resection. Negative resection margins were obtained in 98 patients (R0 61 percent). Median cancer-specific and overall survival was 48 months (41.5 percent 5-year survival) and 43 months (36.6 percent 5-year survival), respectively. Margin involvement was a significant predictor of cancer-specific (P<0.001) and overall survival (P<0.02). CONCLUSIONS Resection for recurrent rectal cancer results in good survival with acceptable morbidity, unaffected by the extent of resection. Extended radical resection to obtain clear resection margins is the appropriate management of locally recurrent rectal cancer.

Abstract
BACKGROUND AND OBJECTIVES Facts buried in the mesorectum remain to be unveiled. This study investigated the number, size, and detailed distribution of lymph nodes metastases and micrometastases within the mesorectum of rectal cancer. METHODS Thirty-one patients who underwent total mesorectal excision (TME) were treated with lymph node revealing solution to retrieve lymph nodes, which were submitted to hematoxylin and eosin (HE) examination and immunohistochemical (IHC) staining. RESULTS The mean number of mesorectal nodes per case was 17.7. The mean size of metastatic, micrometastatic, and isolated tumor cells (ITC) harbored nodes was 5.2 mm, 4.5 mm, and 3.3 mm, respectively. Most of the metastatic (92.1%), micrometastatic and ITC-involved nodes (69.2%) were located along the superior rectal artery (SRA). Posterior-wall located tumor might spread along both sides of the mesorectum simultaneously (P = 0.34), while lateral-wall located tumor spread preferably to ipsolateral side versus contralateral side (P = 0.012). CONCLUSION Most of the metastases and micrometastases positive lymph nodes were smaller than 5 mm and distributed along the SRA. The patterns of lymph nodes spread were related to the circumferential situation of tumor in the rectal wall. Surgical excision of the rectal cancer should completely remove the whole mesorectum, especially to avoid any damage of the mesorectum on tumor side.

Abstract
PURPOSE For many years, poor vascularization of the short rectal stump has been considered the main cause of leakage. The purpose of this study was to evaluate the vascularization of the rectal stump after total mesorectal excision. METHODS We studied the iliac vascularization on 28 volunteers with healthy rectum to have an anatomic basis. Then, we studied the vascularization of the rectal stumps after total mesorectal excision by using angio computed tomography at seven and three months after operating on 22 patients; we validated this technique by studying the vascularization using angio computed tomography in 18 rectal specimens from cadavers. RESULTS Both in healthy rectums and in rectal stumps after total mesorectal excision, there is good vascularization sustained by middle and inferior rectal arteries. The former is more important and frequent as described in previous literature. CONCLUSIONS The vascularization of the short rectal stump is generally well represented even after total mesorectal excision.

Abstract
OBJECTIVE Despite improvement in management of primary rectal cancer, 2.6-32% of patients develop local recurrence. A proportion of these patients can be amenable to salvage surgery. The present article reviews the evidence for and against the surgical management for local recurrence of rectal cancer, the role of adjuvant and intraoperative radiotherapy (IORT), and evaluates short and long-term outcomes. METHOD A literature search was performed using Medline, Embase, Ovid and Cochrane database for studies between 1980 and 2005 assessing surgical management of local recurrence of rectal cancer and the evidence was critically evaluated. RESULTS Nearly 50% of rectal cancer recurrences are local and are therefore potentially amenable to curative resection. Preoperative imaging is important for appropriate selection of patients for surgery and preoperative adjuvant therapy is essential. Five-year survival following resection ranges from 18% to 58% with 5-year survival following complete resection of over 35% though morbidity ranges from 21% to 82%. Neoadjuvant radiotherapy is beneficial and IORT may have a contributory role in treatment. Aggressive surgical treatment favourably affects quality of life and is cost effective. Surgery for local recurrence can result in significant long-term survival with acceptable morbidity and improved quality of life in appropriately selected patients. Assessment in a specialist centre familiar with these techniques is essential.

Abstract
The goal of this review is to outline some of the important surgical issues surrounding the management of patients with early (T1/T2 and N0), as well as locally advanced (T3/T4 and/or N1) rectal cancer. Surgery for rectal cancer continues to develop towards the ultimate goals of improved local control and overall survival, maintaining quality of life, and preserving sphincter, genitourinary, and sexual function. Information concerning the depth of tumor penetration through the rectal wall, lymph node involvement, and presence of distant metastatic disease is of crucial importance when planning a curative rectal cancer resection. Preoperative staging is used to determine the indication for neoadjuvant therapy as well as the indication for local excision versus radical cancer resection. Local excision is likely to be curative in most patients with a primary tumor which is limited to the submucosa (T1N0M0), without high-risk features and in the absence of metastatic disease. In appropriate patients, minimally invasive procedures, such as local excision, TEM, and laparoscopic resection allow for improved patient comfort, shorter hospital stays, and earlier return to preoperative activity level. Once the tumor invades the muscularis propria (T2), radical rectal resection in acceptable operative candidates is recommended. In patients with transmural and/or node positive disease (T3/T4 and/or N1) with no distant metastases, preoperative chemoradiation followed by radical resection according to the principles of TME has become widely accepted. During the planning and conduct of a radical operation for a locally advanced rectal cancer, a number of surgical management issues are considered, including: (1) total mesorectal excision (TME); (2) autonomic nerve preservation (ANP); (3) circumferential resection margin (CRM); (4) distal resection margin; (5) sphincter preservation and options for restoration of bowel continuity; (6) laparoscopic approaches; and (7) postoperative quality of life.

Abstract
Rectal cancer is a major health concern in the United States, with an estimated 40,570 new cases diagnosed in 2004. There are 4 major goals in the treatment of a patient with rectal cancer: local control; long-term survival; preservation of anal sphincter, bladder, and sexual function; and maintenance or improvement in quality of life. Recent advances have been made in preoperative staging, local and radical surgical therapy, the importance of distal and circumferential resection margins, postoperative preservation of the anal sphincter mechanism and genitourinary function, and the role of laparoscopy in the treatment of these patients. Our aim is to outline some of the important surgical issues surrounding the management of patients with early-stage (T1/T2 N0) or locally advanced (T3/T4 and/or N1) rectal cancer.

Abstract
BACKGROUND Mesorectal excision for rectal cancer has resulted in local recurrence rates of 3-11 per cent compared with up to 38 per cent after conventional methods. The results of a prospective Danish study with a historical control group are presented. METHODS Three hundred and eleven patients with a mobile rectal cancer had mesorectal excision with curative intent performed by certified surgeons and were followed for 3 years. Demographic, perioperative and follow-up data were recorded prospectively. A series of patients who had conventional operations for rectal cancer served as a control group. RESULTS The cumulative 3-year local recurrence rate was 11 per cent after mesorectal excision compared with 30 per cent after conventional surgery (hazard ratio (HR) 0.33 (95 per cent confidence interval (c.i.) 0.21 to 0.52); P < 0.001). Multivariate regression analysis showed that only advanced age (HR 0.97 (95 per cent c.i. 0.94 to 1.00); P = 0.048) and tumour in the lower third of the rectum (HR 0.21 (95 per cent c.i. 0.04 to 1.97); P = 0.075) were marginal independent predictors of local recurrence after mesorectal excision. The cumulative crude 3-year survival rate was 77 per cent after mesorectal excision and 62 per cent after conventional surgery (HR 0.58 (95 per cent c.i. 0.43 to 0.77); P < 0.001). Age was the only independent predictor of death after mesorectal excision (HR 1.04 (95 per cent c.i. 1.02 to 1.07); P = 0.001). CONCLUSION Mesorectal excision is associated with a considerably lower risk of local recurrence and a better survival rate than conventional surgery, and is the optimum method for rectal cancer resection.
