Pure primary choriocarcinoma of the urinary bladder with long-term survival.

Choriocarcinoma was diagnosed in a 77-year-old woman with an acute massive, painless hematuria. One year after anterior pelvic exenteration and ileal conduit, the beta-human chorionic gonadotropin level increased to 934 mIU/mL without any sign of tumor progression. After six courses of chemotherapy (vincristine, actinomycin, and cyclophosphamide), the beta-human chorionic gonadotropin levels returned to normal. To our knowledge, this is the fourth case of pure choriocarcinoma in the bladder, with the longest survival time of 33 months so far.

Large solitary fibrous tumor of the seminal vesicle.

Solitary fibrous tumors show a classic morphologic pattern ("patternless pattern") consisting mainly of a proliferation of bland spindle cells with varying amounts of thick, often hyalinized or keloid-like, intercellular collagen bundles. Immunohistochemistry shows a strong reactivity for CD34 antigen, vimentin, and, in a variable percentage, bcl-2 antigen. We report the case of a 50-year-old man with a large solitary fibrous tumor located in the pelvic cavity with a rare nonspecific histologic pattern of pseudovascular formations. The patient underwent pelvic exenteration with orthotopic continent urinary diversion and sigmoid-J-pouch bowel reconstruction. No signs of tumor recurrence were noted within 24 months of surgery.

Prognostic significance of retrieved lymph nodes per specimen in resected rectal adenocarcinoma after preoperative chemoradiation therapy.

BACKGROUND: Histologic examination of a regional lymphadenectomy specimen ordinarily should include 12 or more lymph nodes. However, in specimens from patients who received preoperative chemoradiotherapy this number has not yet been established. METHODS: From January 1990 to December 2000, 210 patients with rectal adenocarcinoma located between 0 and 10 cm from anal verge with invasion into perirectal fat, tethered or fixed to the pelvis, diagnosed by computed tomography (CT) scan and/or rectal ultrasound were included. All patients received 45 Gy+bolus infusion of 5-FU (450 mg/m2/days 1-5, 28-33 of RT) 4-8 weeks after surgery was performed. Specimens were mapped and sliced. Lymph nodes were studied under clearing or manual techniques. Five-year survival was calculated by Kaplan-Meier method and comparison of groups with log-rank test. Multivariate Cox regression analysis was performed to find risk factors affecting local control and survival. RESULTS: There were 126 males and 84 females; mean age was 55.2 years. Low anterior resection was performed in 112 patients, abdominoperineal resection in 85, and pelvic exenteration in 13. Total retrieved lymph nodes numbered 2,554, of which 252 contained metastasis. The group was divided into patients with 1-10 retrieved lymph nodes (n=119) and patients with > or = 11 retrieved lymph nodes (n=91). Median follow-up was 49 months. Local recurrence was as follows: 15% in patients with specimens containing 1-10 lymph nodes and conversely 7.4% in those with > or = 11 (p=0.01). Five-year survival of patients with 1-10 lymph nodes was 48%, whereas for those with > or = 11 lymph nodes it was 69% (p=0.02). CONCLUSIONS: Retrieval of at least 11 lymph nodes in the surgical specimen is not only a powerful tool to properly stage patients with rectal adenocarcinoma treated with preoperative chemoradiotherapy and surgery, but it is also of prognostic relevance in that 5-year survival and local recurrence were better in this group of patients.

[Preservation of the bladder in rectal cancer with prostatic invasion].

Colorectal cancer in the 2nd commonest cancer in Europe. In 5-10% of cases there is infiltration of urological organs. When infiltration affects the bladder or the prostate, anterior pelvic exenteration is the treatment that achieves the largest percentage of tumor free margins and the best 5-year survival. In very select cases of prostatic infiltration, the bladder can be preserved and prostatectomy and abdominoperineal block resection are carried out fulfilling oncological surgical requirements and producing an important improvement in the patient's quality of life. Owing to the very scarce published literature (two articles with three cases) we contribute our experience of 2 patients who received cytoreducing preoperative radiochemotherapy, prostatectomy and block abdominoperineal amputation and intraoperative radiotherapy. We describe the surgical technique used, which is substantially different from standard prostatectomy and requires good coordination between surgeons and urologists.

Percutaneous endovascular repair of a ureteroarterial fistula with a stent graft.

Ureteroarterial fistula is a rare but life-threatening cause of hematuria. The predisposing factors of a ureteroarterial fistula includes pelvic exenteration, radiation therapy, infection, primary vascular disease, vascular reconstructive surgery, and indwelling ureteral catheters or stents. We report a case of ureteroarterial fistula between the right ureter and a pseudoaneurysm originating from the right proximal external iliac artery in a female patient presenting with intermittent massive hematuria. She had previously undergone an operation for cervical cancer, radiation therapy, and ureteral stent placement. She was treated successfully by percutaneous endovascular stent graft placement to exclude the pseudoaneurysm. Percutaneous stent graft placement appears to be an effective and safe therapeutic alternative in the treatment of ureteroarterial fistula.

Postradiation therapy adenosquamous cell carcinoma of the prostate.

The objective of this study was to present two cases of adenosquamous cell carcinoma of the prostate following radiation therapy. Two patients with history of prostate cancer treated with radiation therapy presented with rectal bleeding and a large ulcerated rectal mass. The rectal biopsy revealed on both cases squamous cell carcinoma. The initial diagnosis was invasive squamous cell carcinoma from anal origin. Both patients underwent pelvic exenteration with continent urinary diversion. After extensive histological sampling and immuno-histochemisty, they were correctly diagnosed of adenosquamous cell carcinoma of the prostate with invasion of the rectum. The patients died 6 and 16 months after surgery with widespread metastases. A review of the literature is presented. Adenosquamous cell carcinoma of the prostate is an unusual histological variant of prostate cancer. To our knowledge, only three cases of adenosquamous cell carcinoma of the prostate following radiation therapy have been reported. The unusual clinical and histopathological features of the two cases reported here led to an initial mistaken diagnosis. Adenosquamous cell carcinoma of the prostate should be considered in the differential diagnosis when a patient with prostate cancer develops a rectal mass or rectal bleeding following radiation therapy and the rectal biopsy reveals squamous cell carcinoma.

Significance of local recurrence of rectal cancer as a local or disseminated disease.

BACKGROUND: The nature of 'local recurrence' of rectal cancer remains unclear. METHODS: Fifty-nine patients with locally recurrent rectal cancer who underwent extended repeat resections including total pelvic exenteration (39) and sacrectomy (43) were reviewed. Twelve patients had distant metastases before or at the time of repeat resection. RESULTS: The 5-year survival rate was 25 per cent. A second recurrence occurred in 45 patients including five of the eight 5-year survivors. Thirty-six of these recurrences had locoregional manifestations and 29 had distant metastases. Of 18 prognostic factors examined, the most significant determinant was the postoperative carcinoembryonic antigen doubling time (CEADT), followed by the preoperative CEADT, carcinoembryonic antigen (CEA) level and occurrence of distant metastases, in decreasing order. Late onset of first recurrence was also a favourable indicator. Thus, the growth rate of the tumour had a more profound impact on survival than the current extent of tumour progression. After operation the CEADT was reduced in patients with second recurrence (P = 0.05). CONCLUSION: Locally recurrent rectal cancer is a manifestation of disseminated disease spreading locoregionally and often to distant organs with a low probability of long-term cure. However, survival varies widely depending on the tumour growth rate, which is biologically predetermined and is also influenced by surgery.

Ureteroarterial fistula controlled by intraluminal ureteral occlusion.

A 73-year-old woman underwent a pelvic exenteration for transitional cell carcinoma of the bladder and radiation-induced rectovaginal fistula. The patient had undergone radical hysterectomy and radiotherapy for cervical cancer 30 years earlier. Fifteen months after the operation, she suffered from ureteroaortic fistula, which was controlled by intraluminal ureteral occlusion using Gianturco coils. During 53 months of follow up, she has been free of hemorrhagic episodes.

Involvement of internal genitalia in female patients undergoing radical cystectomy for bladder cancer: a clinicopathologic study of 37 cases.

Radical cystectomy for invasive bladder cancer in female patients implies anterior pelvic exenteration. The necessity for routine removal of all internal female genitalia has not, as yet, been investigated. The present study was conducted to investigate the involvement of internal genitalia in these patients. Cystectomy specimens from 37 consecutive female patients with bladder cancer were examined for internal genitalia and urethral involvement. Clinical data were retrospectively collected from hospital charts. Thirty-four patients were available for postoperative follow-up. Of the 37 cases, 30 were transitional cell carcinoma (TCC), 4 squamous cell carcinoma, 1 adenocarcinoma, and 2 undifferentiated carcinoma. Uterine involvement was observed in only 1 case: TCC, stage D1, grade IV. All patients had normal ovaries and a normal vagina regardless of tumor site or stage; however, late ovarian and vaginal recurrences developed in one patient, in whom one ovary had been preserved. Sixteen percent of the patients had urethral involvement. We conclude that synchronous or metachronous involvement of female internal genitalia in bladder cancer is uncommon. Preservation of ovaries and vagina in young patients undergoing radical cystectomy may be considered under strict criteria.

Adenoid cystic carcinoma of Bartholin's gland: what is the optimal approach?

AIMS AND METHODS: We report the case of a locally advanced adenoid cystic carcinoma of Bartholin's gland which required posterior pelvic exenteration, radical vulvectomy and ablation of the ischiorectal fossa in order to obtain tumour clearance with negative margins. Including this case, only three pelvectomies have been performed for this disease. This is the first reported case in which a controlateral unsuspected intravulvar metastasis was found on histology. RESULTS AND CONCLUSIONS: No consensus exists on the adequate surgical management of this particular disease. Nevertheless, a review of the literature and this reported case suggest that radical vulvectomy with negative margins should be preferred to wide local excision as the primary surgical procedure. It also suggests that inguinofemoral lymph-node dissection should only be performed when suspect lymph nodes are found at clinical examination.

Quality of life in patients with urinary diversion after operation for locally advanced rectal cancer.

AIMS: When locally advanced or recurrent rectal cancer involves the bladder or prostate, curative treatment often requires pelvic exenteration. The aim was to assess the quality of life (QoL) in disease-free patients with urinary diversion after extensive surgery for advanced rectal cancer. METHODS: Twelve patients with urinary diversion (cases) were compared with 25 randomly selected patients given the same treatment, but without urinary diversion (controls). An age- and gender-adjusted general population was identified (reference). QoL was assessed with the EORTC questionnaires QLQ-C30, QLQ-CR38, and parts of the QLQ-BLM30. RESULTS: The cases did not report significantly worse overall QoL than the controls or the reference population. Both cases and controls had low mean scores of sexual function, and high mean scores of male sexual problems. In the nine cases that had two stomas, overall QoL was not worse than in the control or reference groups. CONCLUSIONS: Tumour-free patients did not report worse QoL scores than the controls or the general population, despite most having two stomas and low sexual function. Fear of reducing the patient's QoL should not be a major contraindication when surgery with urinary diversion is warranted to obtain curative resection.

The partial gluteus maximus musculocutaneous turnover flap. An alternative concept for simultaneous reconstruction of combined defects of the posterior perineum/sacrum and the posterior vaginal wall.

Three cases with posterior perineo-sacral defects are presented. One is a 57-year-old white female following amputation of her rectum for carcinoma, radiation and chemotherapy with a significant residual sacral/perineal defect and loss of the posterior vaginal wall. The two other patients had radical pelvic exenteration after recurrent rectum carcinoma. A new myocutaneous turnover flap as a modification of the conventional gluteus maximus flap was designed to solve the particular reconstructive problems. The flap is based on branches of the inferior gluteal artery. The posterior cutaneous femoral nerve and the motor branches of the inferior gluteal nerve not leading into the muscle portion of the flap are left intact. The skin island can be used for vaginal reconstruction or can be de-epithelialised to fill perineal cavities. This new flap eventually enabled the successful reconstruction of the posterior vaginal wall and appropriate sacral/perineal soft tissue coverage in the first case. In the other patients the flap was used to achieve closure of the deep through-and-through defect acutely in one case, and after a 3-week interval in the other.

Videoendoscopically assisted transvaginal radical cystectomy.

We describe our experience of anterior pelvic exenteration for bladder cancer in women using a combined transvaginal and laparoscopic approach. The feasibility of videoendoscopically assisted transvaginal cystectomy was demonstrated several years ago, but the indications have been greatly reduced by the spreading use of orthotopic neobladders in women. Moreover, nulliparous patients or patients with vaginal atresia are not suitable for this technique, even if the specimen can also be retrieved through the minilaparotomy used for performing urinary diversion. In the last 3 years, we have performed only four additional cases. Nevetheless, the results are satisfactory. We did not have any major intraoperative complication. Patients were discharged after 7 to 11 days (average 8.6 days) without any postoperative complications. The minimum survival was 13 months, and four patients are still alive. The operation itself is not easy and therefore can be offered only by centers where videoendosurgery has already entered common clinical practice.

Treatment strategy for locally recurrent rectal cancer.

Despite radical surgery, up to 33% of patients with rectal cancer will develop locoregional relapse. The management of these patients is particularly challenging. Surgery is the mainstay of treatment for those with a mobile recurrence. However, the majority of patients develop recurrence involving the pelvic wall. In these patients, multimodality therapy including radical surgery and intraoperative radiotherapy have been reported with 5-year survival of up to 31% and local control rates of 50-71%. The most important factor for obtaining long-term local control and survival is R0 resection. Extended surgery such as abdomino-sacral resection has not been popular because of 5-year survival rates of 16-31%, and significant postoperative morbidity. Re-recurrence following surgery occurs locally and in the lung, and remains a significant problem. In surgical treatment for local recurrence, surgeon-related factors are crucial. A staging system using degree of fixation and other prognostic factors should be developed so that appropriate treatment modalities are applied to each case.

The closure of large pelvic defects by extended compound tensor fascia lata and inferior gluteal myocutaneous flaps.

This report describes the use of myocutaneous flaps in two unique situations with extensive pelvic and perineal defects. In the first patient, bilateral tensor fascia lata myocutaneous flaps 10 x 40 cm were rotated posteriorly to cover a perineal defect measuring 15 x 30 cm. In the second patient, bilateral inferior gluteus maximus myocutaneous flaps 10 x 32 cm were rotated to fill a pelvic defect 10 x 15 x 8 cm that remained after a pelvic exenteration and sacral resection. Both flaps were delayed 2 weeks prior to surgery to insure 100% viability.

Intraoperative orthovoltage radiation therapy in the treatment of recurrent gynecologic malignancies.

A Phase I/II study was initiated to evaluate complications of orthovoltage intraoperative radiation therapy utilized in the treatment of patients with incompletely resected recurrent gynecologic malignancies. There were no osseous, vascular, neurologic, or ureteral complications. Of the 23 treated patients, 2 patients (8.7%) had complications outside the treated area. Survival of patients treated with intraoperative radiation therapy was highest among patients treated to a field of < or = 3 cm in greatest diameter and a tumor thickness of < or = 1 mm. A subgroup of patients (5) with microscopically positive margins following total pelvic exenteration demonstrated an absence of recurrence in the treated field. The role of intraoperative radiation therapy (IORT) in the treatment of recurrent and incompletely resectable gynecologic malignancies remains investigational.

Smooth muscle neoplasms of the urinary bladder: a clinicopathologic comparison of leiomyoma and leiomyosarcoma.

We report the clinicopathologic, immunohistochemical, and DNA ploidy findings of 18 leiomyosarcomas of the urinary bladder. In addition, we compare these malignant smooth muscle tumors with 10 cases of urinary bladder leiomyoma. The 14 male and four female patients with leiomyosarcoma ranged in age from 25 to 88 years (mean 64 years). The tumors ranged from 3.0 to 15.0 cm (mean 7.1 cm) in greatest dimension and were moderately to highly cellular, consisting of interlacing fascicles of spindled cells with mild to marked nuclear atypia. Coagulative tumor necrosis was identified in 14 cases (78%), and mitotic activity ranged from 1 to 42 mitotic figures (MF) per 10 high power fields (HPF) (mean 12 MF/10 HPF). Tumors were classified as either high-grade (12 cases) or low-grade (six cases) based on nuclear atypia, mitotic activity, and tumor necrosis. Actin positivity was present in 15 tumors (83%), and desmin immunoreactivity was present in seven tumors (39%). All cases were negative for epithelial markers and S-100. Proliferative activity, as assessed by MIB-1 staining, ranged from 0.1% to 51.4% (median 9.1%). Seven (39%) of the leiomyosarcomas were DNA aneuploid, eight (44%) were tetraploid, and three (17%) were diploid. Five patients underwent radical cystoprostatectomy, one radical cystectomy, seven had partial cystectomy, two underwent pelvic exenteration, and three patients had transurethral resection only. Follow-up information was available on all 18 cases and ranged from 2 to 68 months (mean 22 months). Of the 12 patients with high-grade tumors, six (50%) died of disease from 2 to 20 months (mean 7 months) after diagnosis and three patients (25%) are alive with metastatic tumor. Two of the six patients with low-grade leiomyosarcoma died of tumor, 61 and 68 months after diagnosis. There were five male and five female patients with leiomyoma ranging in age from 22 to 78 years (mean 61 years). The tumors ranged from 0.5 to 4.5 cm (mean 1.6 cm) in greatest dimension, were well circumscribed, and had low cellularity. Mitotic activity, necrosis, and cellular atypia were absent, and the tumors were strongly positive for both actin and desmin. MIB-1 staining ranged from 0% to 3.8% (median 0.8%). Seven (87.5%) of the leiomyomas were DNA diploid or near-diploid and one (12.5%) was DNA aneuploid. Six patients were treated with transurethral resection and four with partial cystectomy. All 10 patients were alive at the last follow-up (mean follow-up 75 months), and no tumor recurred or metastasized. Our study shows that low-grade leiomyosarcomas are capable of malignant behavior, and high-grade leiomyosarcomas appear to behave more aggressively than low-grade tumors. In addition, the diagnosis of urinary bladder leiomyoma should be reserved for noninfiltrative smooth muscle tumors lacking mitotic activity, cytologic atypia, and necrosis.

Adenoid cystic/basal cell carcinoma of the prostate: clinicopathologic findings in 19 cases.

Adenoid cystic/basal cell carcinoma (ACBCC) of the prostate has been considered to have indolent biologic potential. However, outcome data are scant, with only one documented metastasis and death. We describe clinicopathologic features of ACBCC in 19 patients and document outcome in 15. Patients ranged in age from 43 to 83 years. All but one presented with urinary obstruction. ACBCC was diagnosed by transurethral resection in 15 cases, by needle biopsy in 3 cases, and unexpected in 1 case. Four patients had concurrent acinar adenocarcinoma. Histologically, cribriform or adenoid cystic patterns predominated in 12 cases and basal cell carcinoma pattern in 7. Five cases had prominent perineural invasion. ACBCC was immunoreactive for p63 and cytokeratins 7 and 34 beta E12 but not cytokeratin 20. After diagnosis, 5 patients underwent radical prostatectomy, 2 underwent pelvic exenteration, and the rest had no treatment. ACBCC showed extraprostatic extension in 5 cases and involved the bladder margin in 3. Metastases developed in 4 (21%) patients: liver (2), lung (2), bowel (1), and corpus cavernosum (1). In 15 cases with follow-up (0.3-11.8 years), two patients died of cancer (at 1.5 and 3 years after diagnosis), 3 remain alive with cancer, and 10 have no evidence of cancer. Thus, ACBCC of the prostate is a potentially aggressive neoplasm requiring ablative therapy.
