Total pelvic exenteration with preoperative irradiation for advanced primary and recurrent rectal cancer.

OBJECTIVE: To study the complication rate, local recurrence rate, and survival after total pelvic exenteration for primary advanced and recurrent rectal cancer. DESIGN: Prospective study. SETTING: Tertiary referral university hospital, Norway. SUBJECTS: 25 patients who were operated on for primary advanced and 22 for recurrent rectal cancer since 1991; 42 men and 5 women, mean age 64 years (range 44-78). All had preoperative irradiation of 46-50 Gy. MAIN OUTCOME MEASURES: Incidence of major complications, and actuarial 5-year survival and local recurrence rate. RESULTS: Twenty patients had RO resection in the primary group versus seven in the recurrent group. No R2 resections were done in the primary group compared with four in the recurrent group. Half the primary cases (n = 13) had abdominoperineal resections. Hartmann's procedures were common in both groups (n = 8 in each). Postoperative mortality at 30 days was 4% (n = 2) and in-hospital 13% (n = 6). 18 patients had major complications and 12 were reoperated on. Overall 5-year actuarial survival for 43 patients without distant metastases was 28%-those with primary tumours 36%, and those with recurrent tumours 18%-similar to the figures for RO and R1 resections. Actuarial local recurrence at 5 years for primary cancers was 18% compared with 68% for recurrent cancers, again nearly identical to the figures for R0/R1 operations (p = 0.008 and p = 0.03). CONCLUSION: Some patients with advanced rectal cancer either primary or recurrent may benefit from simultaneous en-bloc cystectomy. The higher postoperative morbidity and mortality indicate the need for well-defined indications for this procedure and the necessity for thorough preoperative staging.

Long-term follow-up of continent urinary diversion after pelvic exenteration for gynecologic malignancies.

OBJECTIVE: The objective of this retrospective study was to analyze the long-term outcome of patients undergoing a continent urinary diversion (UD) at the time of pelvic exenteration (PE). PATIENTS AND METHODS: Between February 1993 and January 2001, 60 PE for gynecologic malignancies and requiring a UD were performed. Patient's preference, type of UD planned, type of UD performed, and late urinary morbidity (after day 90) were analyzed. RESULTS: Eighty-two percent of the entire group (49/60) matched preoperatively criteria to have a continent UD and 41 continent UD were eventually performed (87%). Postoperative mortality in patients with a continent UD was 4.9% (2/41) and wasn't related to urinary complications. After a 20-month median follow-up, 18 patients (46%) with a continent UD developed late complications directly UD-related. These complications were: (a) major in 28% (5/18) requiring re-operation in 3 cases or endoscopic treatment in 2 cases; (b) minor in 72% (13/18) constantly medically treated. Chronic diarrhea was more frequent in patient who had small bowel or left colon resection (P < 0.05) and urine leakage was more frequent in patient with higher BMI (P < 0.05). At last follow-up, no patient had stopped self-catheterizations or asked for undiversion. CONCLUSIONS: In our experience, continent UD at the time of PE despite high acceptability and feasibility rate, appeared to be strongly related to specific late complications, uncommon with ileal conduit. However, these complications remained more frequently minor and could be treated safely and conservatively.

Multivariate analysis of factors affecting survival in pelvic exenteration.

Of 153 patients with primary or recurrent pelvic malignancy referred for consideration of exenteration, only 40.6% (62 patients) were found to be suitable for exenteration after full assessment. Thirty percent (46 patients) were found to be inoperable on examination under anesthesia. Of the remaining 107 patients, 33% (35 patients) were found to be inoperable at laparotomy, 9% (10 patients) underwent radical hysterectomy and 58% (62 patients) had an exenterative procedure. One patient had no active disease found on final histologic review of the exenteration surgical specimen and was excluded, as the aim of this study was to look at the prognostic factors affecting survival. There remained 61 patients in the exenteration group who were analyzed. The 2-year survival rate was less than 2% for patients with inoperable disease, 48% for patients who underwent radical hysterectomy and 54.1% for patients who underwent exenteration. The 5-year survival rate for all patients undergoing exenteration for pelvic malignancies was 44% and that for cervical cancer only was 52%. Multivariate analysis of patients who had undergone exenteration showed four significantly poor prognostic factors influencing survival. They were: (a) aged older than 69 years, (b) recurrence of the tumor within 3 years, (c) persistent recurrence, and (d) positive resection margins.

[Anterior pelvic exenteration with ileocystoplasty in advanced cancer of the uterine cervix].

A female patient with the IV grade cervical carcinoma without distant metastases is presented. The patient underwent a radical surgical intervention. An anterior pelvic exenteration with ileocystoplasties was successfully performed. The patient is alive 14 months after the initial treatment. No greater complications were observed during the operation and after it, but in spite of a satisfactory general status, the patient has had nocturnal incontinence all the time. It is believed that this complication is the sequel of the newly formed urinary bladder, as the convolution of the ileum is only 30 cm long which has proved insufficient.

The role of pelvic exenteration in the management of recurrent rectal cancer.

BACKGROUND: Use of extirpative surgery in the setting of recurrent rectal cancer is controversial given the poor overall outcome of such patients and the morbidity associated with exenteration. METHODS: A retrospective review of patients treated for recurrent rectal cancer from 1990 to 2002 was performed. RESULTS: Twenty-two patients underwent pelvic exenteration. Seventeen underwent potentially curative resection, 5 were for palliation only. There was 1 operative death. Fifteen suffered at least 1 complication; 9 suffered multiple complications. Ten patients required readmission to the hospital. The overall disease-free interval was 11 months. Potentially curative and palliative resections resulted in median survivals of 20.4 and 8.4 months, respectively (P = 0.049). CONCLUSIONS: While patients may derive oncologic and palliative benefits from exenteration, the price in terms of operative morbidity remains high. Newer measures of operative morbidity are necessary to better appraise the value of this radical approach to recurrent rectal cancer.

Seven cases of pelvic exenteration combined with sacral resection for locally recurrent rectal cancer.

Local recurrence of rectal cancer following abdominoperineal resection is rarely amenable to limited resection. Carcinoembryonic antigen assay is valuable for diagnosing most recurrent rectal cancers, but it is inadequate for early detection. Pelvic computed tomography examination is very valuable for the early detection and localization of recurrence in relation to pelvic structures and can also serve as a guide in percutaneous needle biopsy of the tumor. Seven patients with deeply invading recurrent lesions underwent pelvic exenteration combined with sacral resection. The ileal segment conduit was used for ureteral urinary diversion. The mean operation time and blood loss were 8.8 hours and 6,200 ml, respectively. No operative deaths were encountered. One patient is alive 22 months postoperatively with no evidence of disease, and another patient is alive 32 months postoperatively with pelvic wall recurrence. This procedure seems a reasonable treatment for palliation and full recovery in certain patients.

[Posterior pelvic exenteration in the treatment of extraperitoneal rectal cancer in females].

Postoperative recurrence is common in the, posterior vaginal wall and intrapelvic genital organs after conventional Mile's operation for extraperitoneal rectal cancer in female patients. We have performed posterior pelvic exenteration (PPE) since 1954 in an attempt to reduce such recurrences. The results of 208 patients treated by PPE were compared with those of 77 patients treated by conventional Mile's operation during 1954-1986. The 5-year survival rate of PPE was 53.15 +/- 1.87% and that of Mile's operation was 51.84 +/- 1.68%; the increase was not significant as more cases of poorer prognosis were selected for PPE. However, the local recurrence rate was lower after PPE than after conventional Mile's operation (4.33%:20.78%), (P less than 0.01). We believe that PPE is indicated in anterior rectal lesions of Dukes A, B or C stage, ulcerative or infiltrative type, or when the recto-uterine pouch is involved. PPE will not increase the operative risk if close attention is paid to hemostasis, facilitated by clamping cutting and suture ligating the lateral vaginal wall in segments.

Results of high dose rate brachytherapy, anterior pelvic exenteration and external beam radiotherapy for carcinoma of the female urethra.

PURPOSE: We evaluated a multimodality approach to locally advanced urethral carcinoma in women. MATERIALS AND METHODS: Between August 1996 and July 1999, 6 women were treated for locally advanced carcinoma of the urethra with anterior pelvic exenteration followed by high dose 192iridium intraoperative radiation therapy. Four of the 6 patients were also treated with neoadjuvant or concomitant platinum based chemotherapy. RESULTS: Two patients had no evidence of disease, 3 had distant metastasis and 2 had local recurrence at a mean followup of 21 months (range 12 to 47). Radiation was relatively well tolerated with no major adverse events. CONCLUSIONS: High dose intraoperative brachytherapy followed by external beam radiation is relatively well tolerated. Local control seems to have improved. We must evaluate a larger cohort of patients to determine this impact of the combined modality on local control and patient survival.

An alternative procedure for the creation of an ileal conduit in patients undergoing pelvic exenteration: dextrotransmesenteric location.

Ileal conduits have long been accepted as a standard method for urinary diversion, but conventional ileal conduits are not always suitable for patients whose ureters are for the greater part compromised by neoplasm or preoperative irradiation, resulting in a shortening of the ureters. Bowel migration into the large cavity, which develops after pelvic organ removal, appears to cause tension on the ureteroileal anastomotic site. Dextrotransmesenteric placement of an ileal conduit may provide easy access to the shortened ureters without exerting pressure on the anastomosis. We employed this procedure in seven patients undergoing pelvic exenteration with relatively minimal morbidity.

Supralevator pelvic exenteration with colonic J-pouch-anal anastomosis and Mainz pouch operation with anastomosis to the urethra. Report of a case.

This is the first documented case report in which construction of double pouches, a colonic J-pouch and a Mainz pouch with anastomosis to the urethra, was performed in a patient who underwent supralevator pelvic exenteration. We have shown that the operation is feasible; the patient was continent, except for nightly urinary leakage, and was able to defecate and urinate spontaneously without any catheterization. Based on the experience of this case, we believe that this combined operation results in a better quality of life for the patient because of the avoidance of both urinary and fecal stomas. If justified pathologically, this operation may represent an improvement for those patients with extensive cancer of the rectum, which invades the adjacent anterior viscera, or that of the bladder, which invades the posterior viscera.

Pelvic exenteration for carcinoma of the colon and rectum.

Carcinoma of the colon and rectum is one of the most common causes of cancer deaths in the United States. The mortality of patients treated by surgery alone is 55% within 5 years of surgery. Despite efforts to decrease local recurrence and their concomitant problems of pain and disability, a significant number of patients will still have pelvic recurrences that carry a significant morbidity. In selected cases, pelvic exenteration may cure or provide palliation of the symptoms of colorectal carcinoma. Pre-operative evaluation is performed to detect signs of unresectability. During surgery, exploration is performed for evidence of metastases to the liver, omentum, and peritoneum, followed by an assessment of the local extent of the tumor. The margins of resection must be clear even if resection of contiguous organs or bony structures is necessary. The urinary tract is resected with an ileal loop, sigmoid or transverse colon conduits, or continent urinary diversion. Depending upon the involvement of neighboring structures, exenterative pelvic surgery can be modified for organ preservation.

Urinary diversion after total pelvic exenteration for rectal cancer.

BACKGROUND: Total cystectomy is indicated for the treatment of bulky primary rectal cancers as well as previously treated, locally recurrent tumors that invade the bladder, prostate, seminal vesicle, or urethra. We review a 10-year Memorial Sloan-Kettering Cancer Center experience with urinary diversion in this setting. METHODS: Between April 1988 and June 1998, 47 patients underwent urinary diversion during a total pelvic exenteration for rectal cancer. Charts and operative records were reviewed to determine pathological findings, short-term and long-term urological complications, and survival. RESULTS: Forty-seven patients (25 males and 22 females; median age, 62 years; age range, 27-79 years) were included. Sixteen (34%) patients underwent cystectomy for a primary rectal tumor (including 1 for rectal sarcoma and 1 for synchronous invasive bladder cancer), and 31 (66%) patients underwent surgery for a locally recurrent rectal cancer. Thirty (64%) patients underwent preoperative, 18 (38%) underwent intraoperative, and 11 (23%) underwent postoperative radiotherapy. Twenty-six (55%) patients received preoperative and 16 (34%) underwent postoperative chemotherapy. Two patients had continent ileal cecal reservoirs, 1 a colonic conduit, and the remaining 45 had ileal conduits. The tumor invaded the bladder in 24 (51%) patients, the prostate in 5 (11%) patients, and the seminal vesicle in 5 (11%) patients. Complete resection was achieved in 42 (89%) patients. There were a total of eight complications in eight (17%) patients. There were three early complications, two of which were ileoureteral anastomotic leaks, one managed by reoperation, the second by percutaneous drainage, and one moderate hydronephrosis managed expectantly. There were five late complications; three patients had ureteral stricture/stenosis, leading to nephrectomy in one patient and percutaneous stenting in two patients. Two patients developed late hydronephrosis, so far managed expectantly. There was one perioperative death. After a median follow-up of 16.83 months, 20 patients were dead of the disease, 6 were alive with disease recurrence, 2 were dead of other causes, and 19 had no evidence of disease. Three-year actuarial disease-specific survival was 34%. CONCLUSIONS: Complete resection of bulky primary or locally recurrent rectal cancer can be performed with acceptable urological morbidity. Complete resection was obtained in 89% of patients, with 72% having urological organ invasion. Overall urological complications of 17% are acceptably low despite intensive perioperative radiation and chemotherapy. Disease-specific survival in these patients remains limited.
