Abstract
BACKGROUND This retrospective study aimed to demonstrate surgical operative approach of total pelvic exenteration combined with sacral resection with rectal cancer and elucidate the relationships between the level of sacral resection and short-term outcomes. METHODS Twenty cases were selected. Data regarding sex, age, body mass index, neoadjuvant therapy, location of sacral resection ("Upper" or "Lower" relative to the level between the 3rd and 4th sacral segment), operative time, bleeding, and curability (R0/R1) were collected and compared to determine their association with complications exhibiting a Clavien-Dindo grade III. RESULTS The complication rate was significantly higher for recurrent cancers (n = 10, 76.9%) than for primary cancers (n = 1, 14.3%) (P = .007), and for "Upper" resection (n = 8, 72.7%) than for "Lower" resection (n = 3, 33.3%) (P = .078). Significant differences were observed when complication rates for "Lower" and primary cancer resection (n = 3, .0%) were compared between "Upper" and recurrent cancers (n = 8, 100.0%) (P = .007). CONCLUSION In patients with recurrent rectal cancer, "Upper" sacral resection during total pelvic exenteration is associated with a high complication rate, highlighting the need for careful monitoring.

Abstract
OBJECTIVE Magnetic resonance imaging-based subdivision of the pelvis into 7 compartments has been proposed for pelvic exenteration. The aim of the present anatomical study was to describe the topographic anatomy of these compartments and define relevant landmarks and surgical dissection planes. BACKGROUND Pelvic anatomy as it relates to exenterative surgery is complex. Demonstration of the topographic peculiarities of the pelvis based on the operative situs is hindered by the inaccessibility of the small pelvis and the tumor bulk itself. MATERIALS AND METHODS Thirteen formalin-fixed pelvic specimens were meticulously dissected according to predefined pelvic compartments. Pelvic exenteration was simulated and illustrated in a stepwise manner. Different access routes were used for optimal demonstration of the regions of interest. RESULTS All the 7 compartments (peritoneal reflection, anterior above peritoneal reflection, anterior below peritoneal reflection, central, posterior, lateral, inferior) were investigated systematically. The topography of the pelvic fasciae and ligaments; vessels and nerves of the bladder, prostate, uterus, and vagina; the internal iliac artery and vein; the course of the ureter, somatic (obturator nerve, sacral plexus), and autonomic pelvic nerves (inferior hypogastric plexus); pelvic sidewall and floor, ischioanal fossa; and relevant structures for sacrectomy were demonstrated. CONCLUSIONS A systematic approach to pelvic anatomy according to the 7 magnetic resonance imaging-defined compartments clearly revealed crucial anatomical landmarks and key structures facilitating pelvic exenterative surgery. Compartment-based pelvic anatomy proved to be a sound concept for beyond TME surgery and provides a basis for tailored resection procedures.

Abstract
Gastrointestinal cancers are bordered by radiosensitive visceral organs, resulting in a narrow therapeutic window. The search for more efficacious and tolerable therapies raises the possibility that proton beam therapy's (PBT) physical and dosimetric differences from conventional therapy may be better suited to treat both primary and recurrent disease, which carries its own unique challenges. Currently, the maximal efficacy of radiation plans for primary and recurrent anorectal cancer is constrained by delivery techniques and modalities which must consider feasibility challenges and toxicity secondary to exposure of organs at risk (OARs). Studies using volumetric modulated arc therapy (VMAT) and intensity modulated radiation therapy (IMRT) demonstrate that more precise dose delivery to target volumes improves local control rates and reduces complications. By reducing the low-to-moderate radiation dose-bath to bone marrow, small and large bowel, and skin, PBT may offer an improved side-effect profile. The potential to reduce toxicity, increase patient compliance, minimize treatment breaks, and enable dose escalation or hypofractionation is appealing. In cases where prognosis is favorable, PBT may mitigate long-term morbidity such as secondary malignancies, femoral fractures, and small bowel obstruction.

Sphincter-preserving surgery for recurrent pelvic malignancy using a hybrid procedure of open laparotomy and transanal endoscopic approach. Surg Case Rep 2018; 4:33.

Abstract
Background Surgery for the treatment of recurrent pelvic malignancy is challenging. Sphincter-preserving surgery (SPS) has been applied in limited cases. Transanal endoscopic approach (TEA) has been used for primary rectal cancer, predominantly for hybrid transabdominal-transanal total mesorectal excision. Here, we describe the use of TEA as a hybrid approach in a case of recurrent ovarian cancer. Case presentation A 59-year-old woman had recurrence of serous ovarian adenocarcinoma in the vaginal stump, near the site of anastomosis from a rectal resection 18 months previously. We used a hybrid approach comprising conventional open laparotomy and TEA to accomplish sphincter preservation. In addition to sphincter preservation, TEA allowed for the creation of a “terminal” space, which was made by anterior dissection between the rectum and the vagina. We employed TEA to create an opening in the scar tissue along the sacrum, which was used as a “guide” for pelvic dissection to prevent nerve injury. After exteriorization of the tumor, bowel continuity was achieved by hand-sewn coloanal anastomosis with a protective diverting ileostomy. Pathological examination revealed no involvement of the surgical margins. The diverting ileostomy was taken down 8 months postoperatively. Conclusion A hybrid approach comprising conventional open laparotomy and TEA allowed for safe and secure SPS and complete excision of a recurrent pelvic malignancy. This hybrid surgical approach expands the use of SPS in highly selected cases.

Abstract
AIM To assess safety of rectum removal with distal sacral resection. MATERIAL AND METHODS The short-term results of surgical treatment of primary and recurrent locally advanced rectal and anal cancer with sacral fixation have been analyzed. 32 patients underwent combined operations with sacral resection at the level of S2-S5. In 12 patients only one point of tumor fixation (F1) was revealed, 10 patients had two points of fixation (F2), three patients had three fixation points (F3) and in 7 cases the tumor was fixed to four points (F4) of fixation to different pelvic structures. RESULTS AND DISCUSSION Mean intraoperative blood loss and surgery time was 551±81 ml and 320±20 min in cases of sacral fixation only that was significantly lower compared with F2 cases - 1278±551 ml and 433±45 min, F3 cases - 2200±600 ml and 620±88 min, F4 cases - 2157±512.5 ml and 519±52,3 min, respectively (р<0.05). Complications requiring surgical intervention occurred in 9% patients (n=3). Among 23 patients with intact bladder and ureters urinary disorders occurred in 42% (n=10). Resection margin was negative along posterior surface of the specimen in all cases. CONCLUSION Advanced surgery with distal sacral resection is advisable for radical removal of locally advanced and recurrent rectal and anal canal cancer fixed to the sacrum with negative resection margin. These operations are feasible in specialized centers and should be performed by specially trained oncological or colorectal surgeon.

Abstract
Locally advanced T4 rectal cancer represents a complex clinical condition that requires a well thought-out treatment plan and expertise from multiple specialists. Paramount in the management of patients with locally advanced rectal cancer are accurate preoperative staging, appropriate application of neoadjuvant and adjuvant treatments, and, above all, the provision of high-quality, complete surgical resection in potentially curable cases. Despite the advanced nature of this disease, extended and multivisceral resections with clear margins have been shown to result in good oncological outcomes and offer patients a real chance of cure. In this article, we describe the assessment, classification, and multimodality treatment of primary locally advanced T4 rectal cancer, with a focus on surgical planning, approaches, and outcomes.

Abstract
STUDY DESIGN Case report of a patient with primary osteosarcoma of the sacrum who underwent en bloc sacrectomy. OBJECTIVE To describe a novel approach using robotic guidance for sacral tumor resection. SUMMARY OF BACKGROUND DATA En bloc sacrectomy for aggressive primary malignancies or metastatic tumors of the sacrum can be technically challenging. Although imaging can delineate appropriately planned resection margins, the complex anatomy of the spinopelvic junction poses a challenge for the exact intraoperative execution of the preoperative plan. METHODS The patient was a 22-year-old male who was diagnosed with a primary sacral osteosarcoma. The mass extended to the left sacroiliac joint requiring a transiliac osteotomy. Preoperative robotic-guidance software was used allowing for virtual planning of the transiliac osteotomy. RESULTS During surgery, the robot was attached and synchronized with the preoperative imaging. Pilot holes were drilled along the planned iliac resection margin. With rigid tubes placed in the left iliac pilot holes, we passed a series of osteotomes parallel to the tubes to the same depth as our drillings and completed our left iliac osteotomy. Negative tumor margins were achieved and the postoperative course was uneventful. CONCLUSION We report the first case of robotic-guided en bloc transiliac resection of a primary sacral osteosarcoma with extension to the sacroiliac joint. Robotic guidance for tumor resection can be a useful tool in such challenging surgical procedures to fully resect the tumor, while minimizing disruption of the surrounding healthy anatomy.

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

Abstract
BACKGROUND This study aimed to prospectively quantify the frequency of serious bleeding during pelvic surgery for locally advanced or recurrent rectal cancer and review the surgical methods used to control this. METHODS Consecutive cases of pelvic surgery for curative resection of locally advanced or recurrent rectal cancer were prospectively evaluated over a nine-month period. The procedures undertaken included multivisceral resections, sacrectomies or ultra-low anterior resections. Multivisceral resections were defined as pelvic exenterations, extra-levator abdominoperineal resections (ELAPER) and recurrent anterior resections. The primary endpoint was the proportion of patients sustaining major blood loss, defined as ≥1,000 ml. The secondary endpoint was the blood transfusion rate. Haemostatic adjunct use was recorded. RESULTS Twenty-six patients underwent surgery, comprising 11 pelvic exenterations, 3 ELAPERs, 1 recurrent anterior resection, 5 abdominosacral resections and 6 ultra-low anterior resections. The median intraoperative blood loss was 1,250 ml with 53.8 % of the patients sustaining a loss ≥1,000 ml. Fifty per cent of patients required a blood transfusion within 24 h, and one or more haemostatic adjuncts were necessary in 50 % of the cases. Adjuncts used included a fibrinogen/thrombin haemostatic agent in 38.5 % of patients, temporary intraoperative pelvic packing in 11.5 % of patients and preoperative internal iliac artery embolization in 7.7 % of patients. CONCLUSIONS This patient group is at a high risk of intraoperative haemorrhage, and such patients are high consumers of blood products. Haemostatic adjunct use is often necessary to minimize blood loss. We describe our local algorithm to assist in the assessment and intraoperative management of these challenging cases.

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

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

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

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

Abstract
AIM The study was conducted in a dedicated centre treating the majority of Danish patients with intended curative total pelvic exenteration for primary advanced (PARC) or locally recurrent (LRRC) rectal cancer. We compared PARC and LRRC and analysed postoperative morbidity and mortality, and long-term outcome. METHOD There were 90 consecutive patients (PARC/LRRC 50/40) treated between January 2001 and October 2010, recorded on a prospectively maintained database. RESULTS The median age was 63 (32-75) years with a gender ratio of 7 women to 83 men. All patients were American Society of Anesthesiologists level I or II. Sacral resection was performed in five patients with PARC and 15 with LRRC (P=0.002). R0 resection was achieved in 33 (66%) patients with PARC and in 15 (38%) with LRRC, R1 resection in 17 (34%) with PARC and 20 (50%) with LRRC and R2 resection in five (13%) with LRRC. R0 resection was more frequent in PARC (P=0.007). Forty-four (49%) patients had no postoperative complications. Fifty-five major complications were registered. Two (2.2%) patients died within 30 days, and the total in-hospital mortality was 5.6%. The median follow-up was 12 (0.4-91) months. The 5-year survival was 46% for PARC and 17% for LRRC (P=0.16). CONCLUSION Pelvic exenteration is associated with considerable morbidity but low mortality in an experienced centre. Pelvic exenteration can improve long-term survival, especially for patients with PARC. However, pelvic exenteration is also justified for patients with LRRC.

Abstract
Treatment for patients with locally advanced and recurrent rectal cancer differs significantly from patients with rectal cancer restricted to the mesorectum. Adequate preoperative imaging of the pelvis is therefore important to identify those patients who are candidates for multimodality treatment, including preoperative chemoradiation protocols, intraoperative radiotherapy, and extended surgical resections. Much effort should be made to select patients with these advanced tumors for treatment in specialized referral centers. This has been shown to reduce morbidity and mortality and improve long-term survival rates. In this article, we review the best treatment options for patients with locally advanced and recurrent rectal cancer. We also emphasize the necessity of a multidisciplinary team, including a radiologist, radiation oncologist, urologist, surgical oncologist, plastic surgeon, and gynecologist in the diagnosis and treatment of patients with these pelvic tumors.

Abstract
In the last years a wide range of new technique offers the possibility to have R0 resection in colorectal cancer. We report our experience about Single Port Laparoscopic Surgery (SPL) for not advanced right colon cancer and about pelvectomy with cilindric Abdominal Perineal Resection (APR) for advanced rectal cancer. SPL offer mainly cosmetic advantages but also quicker recovery. No touch technique with adequate surgical margin and lymphectomy were respected. Operative time of SPL was 85- 115 minutes, the incision was 5 cm long. There were no complications. Length of hospital stay was 4-6 days. With advanced pelvic cancer, pelvic exenteration with en-bloc resection is indicated. Then we propose a case of a 55 years old woman with a pelvic recurrence from a metastatic rectal cancer involving the right obturator fossa, the vaginal stump, the right ureter. Modern surgical technique give us the chance to offer the most appropriate oncologic surgical treatment.

Abstract
BACKGROUND The results of resection of locally advanced and recurrent rectal cancers, including sacral resection, were analysed critically. METHODS Between 1987 and 2007, 353 patients with locally advanced or recurrent rectal cancer, all treated in a tertiary referral centre, were identified from a prospective database. Twenty-five patients (eight primary and 17 recurrent tumours) underwent en bloc sacral resection. RESULTS A mid-sacral resection was carried out in 12 patients (level S3) and a low sacral resection in 13 (level S4/S5). Nineteen patients had an R0, four an R1 and two an R2 resection. There was no postoperative mortality. Median follow-up was 32 months. Incomplete resection had an independent negative influence on local control (5-year local recurrence rate 42 versus 0 per cent in those with and without incomplete resection; P < 0.001). The 5-year overall survival rate was 30 per cent. Five patients with recurrent tumour had pathological invasion into the sacral bone and none survived beyond 1 year. CONCLUSION Abdominosacral resection can be performed in patients with locally advanced and recurrent rectal cancer. Patients who cannot undergo a complete resection or have clear evidence of cortical invasion have a poor prognosis.

Abstract
BACKGROUND Patients with stage T4 rectal cancer are known to have poor survival and often require pelvic exenteration (PE). We describe the oncologic outcome of PE for patients with clinical T4 rectal cancer over a 30-year period. METHODS Data for 93 patients with primary rectal cancer who underwent PE between 1975 and 2005 were reviewed retrospectively. RESULTS Curative resection was performed in 91 patients (97.9%). Estimated 5-year overall survival (OS) and 5-year recurrence-free survival (RFS) rates were 52% and 46%, respectively. Irradiation was administered in 18 patients (19.4%). Local recurrence was observed in 7 patients, of whom 6 had lymph node (LN) involvement. Estimated local recurrence rate at 2 years was 8.6% (2.0% in node-negative and 16.4% in node-positive patients). Multivariate analysis demonstrated that lateral pelvic LN involvement (P = .03), a carcinoembryonic antigen level of >10 ng/dL (P = .04), and lymphovascular invasion (P = .04) were significantly associated with decreased OS. Only lateral pelvic LN involvement was significantly associated with decreased RFS (P = .01). CONCLUSION For patients with clinical T4 rectal cancer, PE can provide an opportunity for long-term survival and good local control. Patients with lateral pelvic LN involvement should be offered adjuvant treatment pre- or postoperatively to improve prognosis after PE.

Abstract
AIM: To explore the risk factors for local recurrence of middle and lower rectal carcinoma after curative resection.
METHODS: Specimens of middle and lower rectal carcinoma from 56 patients who received curative resection at the Department of General Surgery of Guangdong Provincial People’s Hospital were studied. A large slice technique was used to detect mesorectal metastasis and evaluate circumferential resection margin status. The relations between clinicopathologic characteristics, mesorectal metastasis and circumferential resection margin status were identified in patients with local recurrence of middle and lower rectal carcinoma.
RESULTS: Local recurrence of middle and lower rectal carcinoma after curative resection occurred in 7 of the 56 patients (12.5%), and was significantly associated with family history (χ2 = 3.929, P = 0.047), high CEA level (χ2 = 4.964, P = 0.026), cancerous perforation (χ2 = 8.503, P = 0.004), tumor differentiation (χ2 = 9.315, P = 0.009) and vessel cancerous emboli (χ2 = 11.879, P = 0.001). In contrast, no significant correlation was found between local recurrence of rectal carcinoma and other variables such as age (χ2 = 0.506, P = 0.477), gender (χ2 = 0.102, χ2 = 0.749), tumor diameter (χ2 = 0.421, P = 0.516), tumor infiltration (χ2 = 5.052, P = 0.168), depth of tumor invasion (χ2 = 4.588, P = 0.101), lymph node metastases (χ2 = 3.688, P = 0.055) and TNM staging system (χ2 = 3.765, P = 0.152). The local recurrence rate of middle and lower rectal carcinoma was 33.3% (4/12) in patients with positive circumferential resection margin and 6.8% (3/44) in those with negative circumferential resection margin. There was a significant difference between the two groups (χ2 = 6.061, P = 0.014). Local recurrence of rectal carcinoma occurred in 6 of 36 patients (16.7%) with mesorectal metastasis, and in 1 of 20 patients (5.0%) without mesorectal metastasis. However, there was no significant difference between the two groups (χ2 = 1.600, P = 0.206).
CONCLUSION: Family history, high CEA level, cancerous perforation, tumor differentiation, vessel cancerous emboli and circumferential resection margin status are the significant risk factors for local recurrence of middle and lower rectal carcinoma after curative resection. Local recurrence may be more frequent in patients with mesorectal metastasis than in patients without mesorectal metastasis.

Abstract
AIM To evaluate the risk factors for lateral lymph node metastasis in patients with advanced low rectal cancer, in order to make the effective selection of patients who could benefit from lateral lymph node dissection, as well as the relationship of lateral lymph node metastasis with local recurrence and survival of patients with advanced low rectal cancer. METHODS A total of 96 consecutive patients who underwent curative surgery with lateral pelvic lymphadenectomy for advanced lower rectal cancer were retrospectively analyzed. The relation of lateral lymph node metastasis with clinicopathologic characteristics, local recurrence and survival of patients was identified. RESULTS Lateral lymph node metastasis was observed in 14.6% (14/96) of patients with advanced low rectal cancer. Lateral lymph node metastasis was detected in 10 (25.0%) of 40 patients with tumor diameter >or= 5 cm and in 4 (7.1%) of 56 patients with tumor diameter < 5 cm. The difference between the two groups was statistically significant (c2 = 5.973, P = 0.015). Lateral lymph node metastasis was more frequent in patients with 4/4 diameter of tumor infiltration (7 of 10 cases, 70.0%), compared with patients with 3/4, 2/4 and 1/4 diameter of tumor infiltration (3 of 25 cases, 12.0%; 3 of 45 cases, 6.7%; 1 of 16 cases, 6.3%) (c2 = 27.944, P = 0.0001). The lateral lymph node metastasis rate was 30.0% (9 of 30 cases), 9.1% (4 of 44 cases) and 4.5% (1 of 22 cases) for poorly, moderately and well-differentiated carcinoma, respectively. The difference between the three groups was statistically significant (c2 = 8.569, P = 0.014). Local recurrence was 18.8% (18 of 96 cases), 64.3% (9 of 14 cases), and 11.0% (9 of 82 cases) in patients with advanced low rectal cancer, in those with and without lateral lymph node metastasis, respectively. The difference between the two groups was statistically significant (c2 = 22.308, P = 0.0001). Kaplan-Meier survival analysis showed significant improvements in median survival (80.9 +/- 2.1 m, 95% CI: 76.7-85.1 m vs 38 +/- 6.7 m, 95% CI: 24.8-51.2 m) of patients without lateral lymph node metastasis compared with those with lateral lymph node metastasis (log-rank, P = 0.0001). CONCLUSION Tumor diameter, infiltration and differentiation are significant risk factors for lateral lymph node metastasis. Lateral pelvic lymphadenectomy should be performed following surgery for patients with tumor diameter >or= 5 cm. Lateral lymph node metastasis is an important predictor for local recurrence and survival in patients with advanced low rectal cancer.

Abstract
Abstract
Background
Fibrous tissue around a locally recurrent rectal tumour is an interesting histological feature, but its clinicopathological significance has not been investigated.
Methods
This retrospective study examined clinicopathological findings in 48 patients who underwent curative total pelvic exenteration with distal sacrectomy (TPES) between 1992 and 2004. Data were analysed with respect to fibrosis around the recurrent tumour, categorized into one of three groups: no fibrosis (f0), partial fibrosis (f1) or circumferential fibrosis (f2).
Results
Ten, 17 and 21 patients had f0, f1 and f2 fibrosis respectively, with 5-year survival of none, four and eight patients respectively. The overall survival of patients with circumferential fibrosis was significantly better than that in patients with no fibrosis (P = 0·003). Univariable analysis showed that a high level of sacrectomy (P = 0·036), absence of lymphatic invasion (P = 0·031) and circumferential fibrosis (P = 0·039) were significantly associated with better overall survival. In multivariable analysis, circumferential fibrosis (P = 0·031) and low serum carcinoembryonic antigen levels (P = 0·044) were independent factors for a favourable outcome.
Conclusion
The outcome of patients with locally recurrent rectal cancer after curative TPES appears to be better when circumferential fibrosis is present around the tumour.

Abstract
AIMS To report the role of total pelvic exenteration in a series of locally advanced and recurrent rectal cancers. METHODS In the period 1994-2004, TPE was performed in 35 of 296 patients with primary locally advanced and recurrent rectal cancer treated in the Daniel den Hoed Cancer Center; 23 of 176 with primary locally advanced and 12 of 120 with recurrent rectal cancer. All but one patient received pre-operative External Beam Radiation Therapy (EBRT). After 1997, Intra Operative Radiotherapy (IORT) was performed in case of a resection margin less than 2 mm. RESULTS Overall major complication rates were not significantly different between patients with primary and recurrent rectal cancer (26% vs. 50%, p=0.94). The hospital mortality rate was 3%. The 5-year local control and overall survival of patients with primary locally advanced rectal cancer were 88% and 52%, respectively. In patients with recurrent rectal cancer 3-year local control and survival rates were 60% and 32%, respectively. An incomplete resection, preoperative pain and advanced Wanebo stage for recurrent cancer were negative prognostic factors for both local control and overall survival. CONCLUSION TPE in primary locally advanced rectal cancer enables good local control and acceptable overall survival, thereby justifying the use of the procedure. Patients with recurrent rectal cancer showed a high rate of major complications, a high distant metastasis rate, and a poor overall survival.
