Centralization of rectal cancer surgery improves long-term survival

COLORECTAL DISEASE, Issue 9 2010
M. Hosseinali Khani
Abstract Aim, In 1996, rectal cancer surgery in the Swedish county of Västmanland was centralized to a single colorectal unit. At the same time, total mesorectal excision and multidisciplinary team meetings were introduced. The aim of this audit was to determine the long-term results before and after centralization. Method, All consecutive rectal cancer patients who underwent curative or palliative surgery at one of the county's four hospitals between 1993 and 1996 (n = 133, group 1) were compared with patients operated at the new centralized colorectal unit between 1996 and 1999 (n = 144, group 2). Results, Preoperative radiotherapy was common in both groups, but in group 2, it was planned using MRI. Local recurrences were detected in 8% of all patients operated in group 1 vs 3.5% in group 2 (P = 0.043). The overall 5-year survival for all patients in group 1 was 38 vs 62% in group 2 (P = 0.003). According to multivariate analysis, the new colorectal unit was an independent predictor for improved long-term survival. Conclusion, This population-based audit shows reduced local recurrence rate and prolonged overall survival for rectal cancer patients after centralization to a single colorectal unit with multidisciplinary management and increased subspecialization.

A national cohort study of long-course preoperative radiotherapy in primary fixed rectal cancer in Denmark

COLORECTAL DISEASE, Issue 7Online 2010
S. Bülow
Abstract Objective, Preoperative radiotherapy has been shown to enable a fixed rectal cancer to become resectable which in turn may result in long-time survival. In this study, we analysed the outcome of long-course preoperative radiotherapy in fixed rectal cancer in a national cohort including all Danish patients registered with primary inoperable rectal cancer and treated in the period May 2001 to December 2005. Method, The study was based on surgical and demographic data from a continuously updated and validated national database. In addition, retrospective data were retrieved from all departments of radiotherapy concerning technique of radiotherapy, dose and fractionation and use of concomitant chemotherapy. Outcome was determined by actuarial analysis of local control, disease-free survival and overall survival. Results, A total of 258 patients with fixed rectal cancer received long-course radiotherapy (> 45 Gy). The median age at diagnosis was 66 years (range: 32,85) and 185 (72%) patients were male. The resectability rate was 80%, and a R0 resection was obtained in 148 patients (57% of all patients and 61% of those operated). The 5-year local recurrence rate for all patients was 5% (95% CI: 3,7%), and the actuarial distant recurrence rate was 41% (95% CI: 35,47%). The cumulative 5-year disease-free survival was 27% (95% CI: 22,32%) and overall 5-year survival was 34% (95% CI: 29,39%). Conclusions, This study is the first population-based report on outcome of preoperative long-course radiotherapy in a large unselected patient group with clinically fixed rectal cancer. Most patients could be resected with the intention of cure and one in three was alive after 5 years. [source]


Expression of p53, bcl-2, and bax as predictors of response to radiotherapy in esophageal cancer

DISEASES OF THE ESOPHAGUS, Issue 3 2000
H. Shimoji
The sensitivity of cancers to radiotherapy or chemotherapy may be influenced by susceptibility to apoptosis. We evaluated whether expression of three proteins regulating apoptosis, p53, bcl-2, and bax, could predict the effect of radiotherapy in esophageal cancers. We used immunohistochemical staining for these protein regulators of apoptosis to study biopsy specimens obtained from 25 patients with esophageal squamous cell carcinoma before they underwent preoperative radiotherapy. Effectiveness of radiotherapy was assessed by barium esophagography, esophagoscopy, and computed tomography. Radiotherapy was effective in 12 patients and ineffective in 13 patients. Biopsy specimens from the 25 patients showed expression of p53, bcl-2, and bax to be 48.0%, 32.0%, and 76.0% respectively. Effectiveness of radiotherapy was correlated with p53 expression (p = 0.047), but bcl-2 and bax expression showed no relationship to effectiveness of radiotherapy. Expression of p53 protein in biopsy specimens may predict effectiveness of preoperative radiotherapy in esophageal cancers. [source]


Preoperative chemoradiation versus radiation alone for stage II and III resectable rectal cancer: A systematic review and meta-analysis

INTERNATIONAL JOURNAL OF CANCER, Issue 12 2009
Wim Ceelen
Abstract Combining chemotherapy with preoperative radiotherapy (RT) has a sound radiobiological rationale. We performed a systematic review and meta-analysis of trials comparing preoperative RT with preoperative chemoradiation (CRT) in rectal cancer patients. The Cochrane Central Register of Controlled Trials, Web of Science, Embase and Medline (Pubmed) were searched from 1975 until June 2007. Dichotomous parameters were summarized using the odds ratio while time to event data were analyzed using the pooled hazard ratio for death. From the primary search result of 324 trials, 4 relevant randomized trials were identified. The addition of chemotherapy significantly increased grade III and IV acute toxicity (p = 0.002) while no differences were observed in postoperative morbidity or mortality. Preoperative CRT significantly increased the rate of pathological complete response (p < 0.001) although this did not translate into a higher sphincter preservation rate (p = 0.29). The local recurrence rate was significantly lower in the CRT group (p < 0.001). No statistically significant differences were observed in disease free survival (p = 0.89) or overall survival (p = 0.79). Compared to preoperative RT alone, preoperative CRT improves local control in rectal cancer but is associated with a more pronounced treatment related toxicity. The addition of chemotherapy does not benefit sphincter preservation rate or long-term survival. Future trials should address improvements in the rate of distant metastasis and overall survival by incorporating more active chemotherapy. © 2008 UICC [source]


Concentrated preoperative radiotherapy for resectable gastric cancer: 20-years follow-up of a randomized trial

JOURNAL OF SURGICAL ONCOLOGY, Issue 2 2002
Vitali Skoropad MD
Abstract Background and Objectives The role of radiation therapy in resectable gastric cancer is questionable. To study the value of concentrated preoperative radiotherapy, a randomized clinical trial had been carried out. Methods From 1974 to 1978, 152 patients were randomized and underwent exploratory laparotomy; in 50 patients curative surgery was not possible, while 102 patients satisfied protocol requirements and entered in the trial. Patients in the experimental group were treated with preoperative radiotherapy (20 Gy/5 days) and subtotal or total gastrectomy. Patients in the control group underwent surgery alone. Results Study showed acceptable tolerance of radiotherapy regime with no increase of postoperative mortality and morbidity. There was no significant difference in survival between the two treatment groups (,2,=,0.349, df,=,1, P,=,0.555). Subset analysis also failed to demonstrate significant survival advantages of the combined treatment; however, some positive trends were seen in patients with locally advanced gastric cancer. Conclusions Concentrated preoperative radiotherapy in the dose of 20 Gy is safe and feasible, but seems to be insufficient to improve survival in gastric cancer patients. However, the results are promising in selected subgroups of patients, which encourages future trials with adjuvant radiation therapy. J. Surg. Oncol. 2002;80:72,78. © 2002 Wiley-Liss, Inc. [source]


Psychophysiological Assessment of Sexual Function in Women After Radiotherapy and Total Mesorectal Excision for Rectal Cancer: A Pilot Study on Four Patients

THE JOURNAL OF SEXUAL MEDICINE, Issue 4 2009
Stephanie O. Breukink MD
ABSTRACT Introduction., The potential contribution of psychological and anatomical changes to sexual dysfunction in female patients following short-term preoperative radiotherapy (5 × 5 Gy) and total mesorectal excision (TME) is not clear. Aim., In this study we assessed female sexual dysfunction in patients who underwent radiotherapy and TME for rectal cancer. Main Outcome Measures., Genital arousal was assessed using vaginal videoplethysmography. Methods., Sexual functioning was examined in four patients who had rectal cancer and underwent radiotherapy and TME. All investigations were done at least 15 months after treatment. The results were compared with an age-matched group of 18 healthy women. Results., The patients and healthy controls showed comparable changes in vaginal vasocongestion during sexual arousal, though three out of four patients showed a lower mean spectral tension (MST) of the vaginal pulse compared with healthy controls. Subjective sexual arousal was equivalent between the two groups. Conclusions., In this study the changes of genital and subjective sexual arousal after erotic stimulus condition between patients and healthy controls were not different, though lower MST of the vaginal pulse was found in three out of four patients compared with healthy women. Additional work, however, must be performed to clarify the mechanisms of sexual dysfunction following treatment of rectal cancer.

Is palliative resection of the primary tumour, in the presence of advanced rectal cancer, a safe and useful technique for symptom control?

ANZ JOURNAL OF SURGERY, Issue 4 2004
Nasser Al-Sanea
Introduction: At some time, every general surgeon will be faced with the task of trying to decide what to do with a patient who presents with rectal cancer and unresectable distant metastases. How safe is resectional surgery? What sort of palliation may be expected following resection of the primary tumour? In an attempt to answer these questions, the management and outcomes of all patients with rectal cancer and distant metastases, who were primarily referred to the colorectal unit at King Faisal Specialist Hospital were examined. Methods: All patients who underwent primary surgery for rectal cancer in the presence of metastatic disease were identified. The charts of these patients were examined and their morbidity, mortality and survival were determined. Results: Over an 8-year period 22 patients (average age 54 years) underwent rectal resectional surgery in the presence of metastatic disease. There were 13 men and nine women. The commonest complaint was rectal bleeding. All patients had chest radiographs. Pulmonary metastases were identified in four patients. Nineteen abdominal and pelvic computed tomography scans were performed and eight showed evidence of metastases. Skeletal radiographs in two patients showed evidence of bone metastasis. At operation, intraperitoneal metastases were found in 18 patients. Nine of these were not identified preoperatively. Six patients underwent abdomino-perineal resection, nine anterior resection and seven a Hartmann's procedure. Eight patients developed a significant postoperative complication and one died 42 days after surgery. The mean length of hospital stay was 18.6 days. Nine patients received preoperative radiotherapy. Four patients had palliative radiotherapy, two for bony, one for liver and one for peritoneal metastases. Patients were followed up for a mean of 1.1 years. During follow up, 11 returned to the emergency room on 24 occasions. Two patients required readmission. No patient had further rectal bleeding. The mean survival was 1.3 years. Conclusion: Patients with rectal cancer and unresectable distant metastases can be successfully palliated by resection of the primary tumour with low morbidity and mortality. The early involvement of a palliative care team facilitates patient management and helps patients enjoy what remains of the rest of their lives at home, in comfort and with good symptom control.

Impact of radiotherapy on local recurrence of rectal cancer in Norway

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 1 2007
M. H. Hansen
Background: The purpose of this study was to analyse the impact of radiotherapy on local recurrence of rectal cancer in Norway after the national implementation of total mesorectal excision (TME). Methods: This was a prospective national cohort study of 4113 patients undergoing major resection of rectal carcinoma between November 1993 and December 2001. Results: The proportion of patients who had radiotherapy before or after operation increased from 4·6 per cent in 1994 to 23·0 per cent in 2001. The cumulative 5-year local recurrence rate decreased from 16·2 to 10·7 per cent. Multivariable analysis showed that preoperative radiotherapy significantly reduced local recurrence (hazard ratio 0·59 (95 per cent confidence interval 0·39 to 0·87)). The use of preoperative radiotherapy in patients from a local hospital offering radiotherapy was 50 per cent higher than that for patients from a hospital without such services (P = 0·003); cumulative 5-year local recurrence rates for these patients were 10·6 and 15·8 per cent respectively (P < 0·001). Conclusion: Following national implementation of TME for rectal cancer, increased use of preoperative radiotherapy appeared to reduce recurrence rates further.

Primary rectus abdominis myocutaneous flap for repair of perineal and vaginal defects after extended abdominoperineal resection

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2005
S. W. Bell
Background: Significant morbidity can result from perineal wounds, particularly after radiotherapy and extensive resection for cancer. Myocutaneous flaps have been used to improve healing. The purpose of this study was to evaluate the morbidity and results of primary rectus abdominis myocutaneous flap reconstruction of the vagina and perineum after extended abdominoperineal resection. Methods: Thirty-one consecutive patients undergoing one-stage rectus abdominis myocutaneous flap reconstruction of extensive perineal wounds were studied prospectively. Twenty-six patients had surgery for recurrent or persistent epidermoid anal cancer or low rectal cancer, and 21 had high-dose preoperative radiotherapy. Results: Three weeks after the operation, complete healing of the perineal wound was seen in 27 of the 31 patients. There were nine flap-related complications including three patients with partial flap necrosis, two with vaginal stenosis, one with vaginal scarring, one with small flap disunion and two with weakness of the anterior abdominal wall. There were no unhealed wounds at the completion of follow-up (median 9 months). Conclusion: The transpelvic rectus abdominis myocutaneous flap for the reconstruction of large perineal and vaginal wounds achieves wound healing with only moderate morbidity in the majority of patients after extensive abdominoperineal resection with or without radiotherapy.

Optimal preoperative assessment and surgery for rectal cancer may greatly limit the need for radiotherapy

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 8 2003
M. Simunovic
Background: Radiation is being used increasingly in the management of patients with rectal cancer. Over the past decade the Basingstoke Colorectal Research Unit has combined precision total mesorectal excision with the highly selective use of preoperative radiotherapy. Methods: One hundred and fifty consecutive patients who underwent major surgical excision for cancers of all stages comprised the study group. Preoperative clinical assessment was based largely on tumour size, fixation and distance from the anal verge. Only preoperative radiotherapy was considered and this only for tumours judged to be at high risk of mesorectal fascia involvement. Results: During a 5-year period 35 of 150 patients were selected for preoperative irradiation. In the non-irradiated patients the local recurrence rate after a median follow-up period of 870 (range 51,1903) days was 2·6 per cent (three of 115 patients), compared with 17·1 per cent (six of 35 patients) in those chosen for irradiation. Sixty patients (52·2 per cent) who were not irradiated were node positive. The local recurrence rate for the whole group was 6·0 per cent. Conclusion: The great majority of patients undergoing major excision for rectal cancer can be managed without radiation therapy if the preoperative assessment of the mesorectal fascia and surgery are performed optimally.

Laparoscopic intersphincteric resection with coloplasty and coloanal anastomosis for mid and low rectal cancer,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2003
E. Rullier
Background: The feasibility of laparoscopic rectal resection in patients with mid or low rectal cancer was studied prospectively with regard to quality of mesorectal excision, autonomic pelvic nerve preservation and anal sphincter preservation. Methods: Laparoscopic rectal excision was performed in 32 patients (21 men) with rectal carcinoma located 5 cm from the anal verge. Most patients had T3 disease and received preoperative radiotherapy. The surgical procedure was performed 6 weeks after radiotherapy and included total mesorectal excision, intersphincteric resection, transanal coloanal anastomosis with coloplasty and loop ileostomy. Results: Three patients needed conversion to a laparotomy. Postoperative morbidity occurred in ten patients, related mainly to coloplasty. Macroscopic evaluation showed an intact mesorectal excision in 29 of 32 excised specimens; microscopically, 30 of the 32 resections were R0. Sphincter preservation was achieved in 31 patients. The hypogastric nerves and pelvic plexuses were identified and preserved in 24 of the 32 patients. Sexual function was preserved in ten of 18 evaluable men. Conclusion: A laparoscopic approach can be considered in most patients with mid or low rectal cancer. Copyright © 2003 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

Preoperative staging of rectal cancer allows selection of patients for preoperative radiotherapy

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 5 2000
A. F. Horgan
Background: Variability in rates of local recurrence following resection of rectal cancer has led to the suggestion that all patients should undergo preoperative radiotherapy. This centre employs a selective policy of radiotherapy only in patients with evidence of advanced local disease determined by preoperative staging. Methods: A retrospective review was carried out of 114 consecutive patients with rectal cancer. Patients were divided before operation into palliative and curative groups based on preoperative staging. Only patients in the palliative group were offered preoperative radiotherapy. Total mesorectal excision (TME) was performed for all tumours of the middle or lower rectum. Results: The perioperative mortality rate was 0·9 per cent and anastomotic dehiscence occurred in 2·8 per cent. Local recurrence developed in 4 per cent of patients in the ,curative' group and in seven of 15 of those assigned to the palliative group before operation (P < 0·01). Positive lateral resection margins were significantly associated with a risk of subsequent recurrence (ten of 13 versus three (3 per cent) of 93; P < 0·001). Conclusion: Preoperative adjuvant radiotherapy can be omitted reasonably in patients in whom there is no evidence of locally advanced disease, provided that adequate surgery, incorporating TME for low tumours, is performed. © 2000 British Journal of Surgery Society Ltd [source]


The predictive value of apoptosis protease-activating factor 1 in rectal tumors treated with preoperative, high-dose-rate brachytherapy

CANCER, Issue 2 2006
Inti Zlobec M.Sc.
Abstract BACKGROUND The objective of this study was to assess the value of apoptosis protease-activating factor 1 (APAF-1) as a predictive marker of response in rectal tumors treated with preoperative, high-dose-rate endorectal brachytherapy. METHODS Immunohistochemistry for APAF-1 was performed on 94 rectal tumor biopsy specimens from patients who were treated on a preoperative, high-dose-rate brachytherapy protocol. Tumors were considered positive when > 10% of tumor cells were immunoreactive. The association between APAF-1 expression and tumor response was made using the chi-square test. RESULTS Forty-four tumors (43%) were positive for APAF-1. Thirty tumors had complete pathologic tumor regression after preoperative radiotherapy. Of these, 18 tumors were positive for APAF-1. A partial response occurred in 35 tumors. Eighteen tumors (51%) were positive for the protein. Only 8 of 29 nonresponsive tumors (28%) were immunoreactive for APAF-1. A significant association was found between complete tumor regression and positive APAF-1 status (P = 0.018). APAF-1 expression in partially responsive tumors was significantly greater than in nonresponsive tumors (P = 0.03). CONCLUSIONS APAF-1 expression in pretreatment rectal tumor biopsy specimens may be useful as a predictive marker of response to preoperative radiotherapy in patients with rectal carcinoma.

Results of multimodality therapy for squamous cell carcinoma of maxillary sinus

CANCER, Issue 5 2002
Ken-ichi Nibu M.D., Ph.D.
Abstract BACKGROUND A wide variety of modalities, including surgery, radiation therapy, and chemotherapy, alone or in combination, have been used for the treatment of squamous cell carcinoma (SCC) of the maxillary sinus to obtain better local control and maintain functions. However, there is still much controversy with regard to the optimum treatment. METHODS From 1987 to 1999, 33 patients with SCC of maxillary sinus were treated at the Department of Otolaryngology,Head and Neck Surgery, University of Tokyo Hospital. The treatment consisted of 30,40 grays (Gy) of preoperative radiotherapy with concomitant intraarterial infusion of 5-fluorouracil and cisplatin followed by surgery and 30,40 Gy of postoperative radiotherapy, for tumors without skull base invasion. For tumors invading the skull base, preoperative systemic chemotherapy with or without radiotherapy was performed, instead of intraarterial chemotherapy, then followed by skull base surgery. The surgical procedures varied according to the extent of tumor. Results were compared with those of the 108 patients treated in our hospital from 1976 to 1982. RESULTS Partial maxillectomy was performed in 2 T2 patients and 12 T3 patients. Total maxillectomy was performed in 1 T2 patient, 3 T2 patients, and 7 T4 patients. Skull base surgery was performed in eight T4 patients. Orbital content and hard palate were preserved in 22 patients and 18 patients, respectively. The overall 5-year survival rates were 86% in T 3 patients and 67 % in T4 patients, respectively. CONCLUSIONS Our multimodal treatment has provided favorable local control and survival outcome with good functional results. Cancer 2002;94:1476,82. © 2002 American Cancer Society.

A national cohort study of long-course preoperative radiotherapy in primary fixed rectal cancer in Denmark

COLORECTAL DISEASE, Issue 7Online 2010
S. Bülow
Abstract Objective, Preoperative radiotherapy has been shown to enable a fixed rectal cancer to become resectable which in turn may result in long-time survival. In this study, we analysed the outcome of long-course preoperative radiotherapy in fixed rectal cancer in a national cohort including all Danish patients registered with primary inoperable rectal cancer and treated in the period May 2001 to December 2005. Method, The study was based on surgical and demographic data from a continuously updated and validated national database. In addition, retrospective data were retrieved from all departments of radiotherapy concerning technique of radiotherapy, dose and fractionation and use of concomitant chemotherapy. Outcome was determined by actuarial analysis of local control, disease-free survival and overall survival. Results, A total of 258 patients with fixed rectal cancer received long-course radiotherapy (> 45 Gy). The median age at diagnosis was 66 years (range: 32,85) and 185 (72%) patients were male. The resectability rate was 80%, and a R0 resection was obtained in 148 patients (57% of all patients and 61% of those operated). The 5-year local recurrence rate for all patients was 5% (95% CI: 3,7%), and the actuarial distant recurrence rate was 41% (95% CI: 35,47%). The cumulative 5-year disease-free survival was 27% (95% CI: 22,32%) and overall 5-year survival was 34% (95% CI: 29,39%). Conclusions, This study is the first population-based report on outcome of preoperative long-course radiotherapy in a large unselected patient group with clinically fixed rectal cancer. Most patients could be resected with the intention of cure and one in three was alive after 5 years. [source]


Use of myocutaneous flaps for perineal closure following abdominoperineal excision of the rectum for adenocarcinoma

COLORECTAL DISEASE, Issue 6 2010
S. Chan
Abstract Introduction, Abdominoperineal excision (APE) following radiotherapy is associated with a high rate of perineal wound complications. The use of myocutaneous flaps may improve wound healing. We present our experience using myocutaneous flaps for immediate reconstruction. Method, Prospective data were collected on patients undergoing APE from October 2003 to December 2008. Patient demographics, operating time, wound complications and length of stay were recorded. Results, Fifty-one patients underwent APE for rectal adenocarcinoma, 21 had primary closure and 30 had myocutaneous flap closure (24 VRAM, 6 gracilis). The proportion of patients undergoing preoperative radiotherapy in each group were 62% and 93% respectively (P = 0.011). There were no major complications following primary closure of the unirradiated perineum. Major perineal wound complications requiring reoperation or debridement were seen in three (14%) patients following primary closure and five (17%) patients with flap closure. After radiotherapy, closure with a flap reduced the length of stay from 20 to 15 days, but this difference was not statistically significant (P = 0.36). Conclusion, The use of flap closure in irradiated patients is associated with fewer perineal complications and a shorter hospital stay. [source]


Rectal cancer: involved circumferential resection margin , a root cause analysis

COLORECTAL DISEASE, Issue 5 2009
H. Youssef
Abstract Introduction, An involved circumferential resection margin (CRM) following surgery for rectal cancer is the strongest predictor of local recurrence and may represent a failure of the multidisciplinary team (MDT) process. Aim of study, The study analyses the causes of positive CRM in patients undergoing elective surgery for rectal cancer with respect to the decision-making process of the MDT, preoperative rectal cancer staging and surgical technique. Method, From March 2002 to September 2005, data were collected prospectively on all patients undergoing elective rectal cancer surgery with curative intent. The data on all patients identified with positive CRM were analysed. Results, Of 158 patients (male:female = 2.2:1) who underwent potentially curative surgery, 16 (10%) patients had a positive CRM on postoperative histology. Four were due to failure of the pelvic magnetic resonance imaging (MRI) staging scans to predict an involved margin, two with an equivocal CRM on MRI did not have preoperative radiotherapy, one had an inaccurate assessment of the site of primary tumour and in one intra-operative difficulty was encountered. No failure of staging or surgery was identified in the remaining eight of the 16 patients. Abdominoperineal resection (APR) was associated with a 26% positive CRM, compared with 5% for anterior resection. Conclusion, No single consistent cause was found for a positive CRM. The current MDT process and/or surgical technique may be inadequate for low rectal tumours requiring APR. [source]


The impact of pre- or postoperative radiochemotherapy on complication following anterior resection with en bloc excision of female genitalia for T4 rectal cancer

COLORECTAL DISEASE, Issue 4 2009
B. Szynglarewicz
Abstract Objective, The aim of the study was to assess the mortality and morbidity following extended anterior resection with excision of internal female genitalia combined with pre- or postoperative chemoradiotherapy in women with extensive rectal cancer. Method, The study included a consecutive series of 21 women with T4 adenocarcinoma of the rectum infiltrating the reproductive organs treated with curative intent between 1997 and 2003. All patients had an extended anterior sphincter preserving resection of the rectum (total mesorectal excision) and hysterectomy with or without posterior vaginal wall excision. In all patients, surgery was combined with adjuvant radiochemotherapy. Ten patients received preoperative radiotherapy (50.4 Gy) concurrently with two courses of chemotherapy [fluorouracil with folinic acid (FA)] followed by surgery within 6,8 weeks and subsequently four courses of postoperative chemotherapy. Eleven received postoperative chemoradiotherapy (50.4 Gy plus fluorouracil with FA). Results, There was no postoperative mortality. Postoperative complications were observed in 57% patients (early in 14% and late in 52%). These included: anterior resection syndrome with anorectal dysfunction in 52% (requiring proximal diversion in 5%), urinary complications in 24% (complete incontinence requiring a permanent catheter in 5%). In addition, postoperative acute bleeding requiring relaparotomy, delayed wound healing caused by superficial infection, anastomotic leakage, prolonged bowel paralysis, benign rectovaginal fistula and anastomotic stricture occurred (5% each). The risk of postoperative morbidity (52%) was similar for patients with or without preoperative radiochemotherapy. Conclusion, Despite this aggressive therapeutic approach, most postoperative complications were transient or could be treated. Preoperative radiochemotherapy did not increase the risk of morbidity.
