In spite of the improvement of surgical techniques used alone or in combination with preoperative radiation therapy, more than 50% of the patients with infiltrating transitional cell carcinoma (TCC) of the bladder die of distant metastases. Systemic antiblastic polychemotherapy has been reported to achieve a complete remission rate of approximately 30% in patients with infiltrating bladder TCC, although there are still doubts relative to the duration of such complete remissions. This study investigated the efficacy and tolerability of a preoperative chemo- and radiotherapeutic treatment modality and the possibility of performing preservative surgery. Thirty-seven patients with bladder TCC stage T2-T4, N0, M0, have been subjected to neoadjuvant chemotherapy according to the "Rescue M-VEC" scheme of methotrexate 30 mg/m2 +folinic acid 15 mg. after 24 hours on days 1, 15, 22; vinblastine 3 mg/m2 on days 1, 15, 22; epidoxorubicin 30 mg/m2 on day 1 and cisplatin 70 mg/m2 on day 1. The course was repeated from day 29. After 2 "Rescue M-VEC" courses, the patients received pelvic cobalt tele-therapy (CTT) combined with cisplatin 24 mg/m2/week. The patients were then restaged. Those with complete remission (CR) received consolidation radiotherapeutic boost combined with cisplatin 24 mg/m2/week, avoiding radical cystectomy. Such treatment was also given to patients with significant partial remission (PR) who had undergone TUR or partial cystectomy. In all the remaining cases we carried out radical cystectomy. We obtained 45.7% CR, 31.4% PR and 22.8% were non-responders (NR), of 35 patients who were evaluable at restaging. Only 9 radical cystectomies were performed in this series. The overall survival rate was 80.6% at a mean follow-up of 18.1 months.(ABSTRACT TRUNCATED AT 250 WORDS)

Perineal implantation of urinary bladder cancer in a 57-year-old male is reported. The patient had been suffering from incomplete paraplegia and neurogenic bladder for these 29 years because of accidental injury of lumbar spinal cord with episodes of bladder stones two times and right epididymitis three times, and presented urinary leakage from a perineal fistula. The fistula orifice was surrounded by a hard mass lesion. Bilateral swelling of inguinal lymph nodes was present. Fistulogram and voiding cysto-urethrography revealed reflux from posterior urethra to the fistula through right vas and epididymis. Histological diagnosis of resected perineal mass and biopsied left inguinal lymph node was transitional cell carcinoma with predominant metaplasia of squamous cell carcinoma. Tissues obtained by TUR-biopsy of a mass lesion at bladder wall was also histologically diagnosed transitional cell carcinoma with metaplasia of squamous cell carcinoma. The present case indicates implantation of a bladder tumor to perineum by urethero-vasal reflux and metastases to inguinal lymphnodes from the perineal lesion.

A case of malignant fibrous histiocytoma (MFH) of the urinary bladder was presented. A 59-year-old man visited our hospital with a chief complaint of gross hematuria with clots. Intravenous urography revealed a filling defect on the left side of the bladder. CT scan demonstrated that the tumor invaded the bladder wall deeply. The histology of the biopsy specimens obtained by TUR was suspected to be transitional cell carcinoma. Bleeding from the bladder was so severe that a lot of units of blood transfusion were required in order to compensate for anemia before total cystectomy was performed. The tumor was hemispheric, moderately demarcated, measuring 5.5 cm x 4.0 cm x 5.5 cm, and located at the posterior wall. The histological diagnosis was malignant fibrous histiocytoma, inflammatory type, with venous invasion of tumor cells. Postoperatively, the patient received 5 courses of combination chemotherapy of adriamycin (100 mg/body, day 1) and dacarbazine (400 mg/body, day 1-5). He is alive with no evidence of local and metastatic disease 24 months after operation, in spite of the poor prognosis predicted from the histological findings. MFH of the urinary bladder is very rare. We also made a brief review of prior reports on this disease.

A retrospective study was conducted in patients with bladder tumors equal to or higher than stage T1 to determine the influence on survival of tumor cell invasion of the microscopic lymphatic vessels of the bladder wall. Sixty-two patients were studied (34 recurrent and 28 primary tumors). Evidence of microscopic lymphatic invasion was disclosed following TUR (48 cases) and cystectomy (14 cases). Overall and with a mean follow up of 27 months, 25% of the patients are alive and tumor free, 51.6% had died from the tumor (90% less than 3 years following diagnosis). Forty-five percent had lymph node metastasis and 56.6% node and organ metastases. For a time interval of over 6 months between the diagnosis of L + and definitive treatment, there was an 80% mortality versus 43% when treatment was concurrent with diagnosis. Finally, survival was much better in patients submitted to radical surgery. We can conclude from the present study that evidence of tumor invasion of the lymphatic vessels must be routinely sought by the pathologist in order to identify those patients with a high probability of tumor dissemination.

Since 1981 a curative radiation treatment was performed in 84 patients with prostatic carcinoma. Previously, in 37 cases a transurethral resection of bladder outlet obstruction was done and in 18 patients a pelvic lymph node dissection was performed, whereas 29 patients were without operative therapy. Mild side effects of radiation could observed in all 3 groups in nearly the same portion (59/56/65%). However, in the group with transurethral resection after follow-up of 4,4 years severe late complications were found (cystitis, incontinence, urethral fistula). Therefore, radiation treatment of prostatic carcinoma after transurethral resection was abandoned. The cumulative 5-year-survival rate was 63% and in the TUR group only 41%. 9 out of 10 patients with histological verified lymph node metastases and radiation treatment are alive after mean follow-up time of 3.1 years without evidence of recurrent disease.

A case of male urethral melanoma is reported. A 85-year-old male with a 2-month history of progressive, severe obstructive urinary symptoms and bloody urethral discharge was referred to us after an unsuccessful management at a local doctor. Physical examination revealed an ill looking old man with no evidence of nevi or other cutaneous pigmentation looking like malignant melanoma. Neither palpable periurethral mass nor inguinal lymphadenopathy was noted. RUG showed an irregular shadow defect in bulbous urethral regions. In cystourethroscopy, a raised nodular reddish black lesion in the urethra without adjacent satellite lesions was found. Histologic examination revealed that the tumor was made up of closely spaced, anaplastic, spheroidal or polyhedal cells. Intracellular brown pigment was richly present, gave a negative reaction for iron, but stained black with Masson-Fontana's method. Further examination for evaluating metastases including bone scintigraphy, computer tomographic scan, chest X-ray film were negative. Due to his poor risk, radical operation such as cystourethrectomy might be undesirable. We performed TUR to relieve urethral obstruction, because the patient refused cystostomy. He died of wide spread metastases at 6 months after the operation. This case seems to be the second report in the Japanese literature.

In October 1984, a prospective pilot study aiming to evaluate the feasibility and to preliminarily test the efficacy of the chemotherapy--surgery sequence in locally advanced bladder carcinoma was started at our institutions. Chemotherapy consisted of adriamycin 50 mg mq-2 and cisplatin 50 mg mq-2 on day 1 and fluorouracil 500 mg mq-2 and teniposide 100 mg mq-2 on days 1 and 8; chemotherapy was repeated every 3 weeks for three cycles and followed by surgery (radical cystectomy; TUR if radical surgery medically contraindicated). The characteristics of the 28 patients so far treated include: T3b in 26 patients, local relapse after surgery in two, nodal metastases in seven. Twenty-five patients were male and three female, median age was 61 yr (range 42-75). Clinical response following chemotherapy was: complete remission (CR) in five patients, partial remission (PR) in 15, stable disease (SD) in three, progression (PRO) in two. Three patients are not evaluable. Treatment was moderately well tolerated. Thirteen patients underwent radical surgery, three exploratory surgery, three TUR; refusal in three patients, early death in two, too early in one. No evidence of disease was found in the surgical specimen of five patients (three CR, two PR), microscopic residual disease in four PR patients, gross residual disease in 11 patients (one CR, six PR, two SD, two PRO). Actuarial median survival (all 28 patients) is 45% at 36 months. These preliminary results suggest that the combination of chemotherapy and surgery is feasible and may be effective in these poor prognosis patients.

Over the last 11 years we have treated 47 patients with infiltrating bladder carcinomas with the neodymium:YAG laser alone or in combination with TUR. After a mean observation period of 3 1/2 years (19-133 months) 39 patients (83%) were still alive. Only two of them showed tumor dissemination. Thirteen patients (27.7%) had no recurrent disease after laser therapy. Mostly heterotopic recurrences with no tumor progression were found in 23 patients (48.9%). Six patients (12.8%) developed recurrences with progression, including two cases with pelvic lymph node metastases. Five patients (10.6%) died of their tumor disease and three of myocardial infarction, having shown no signs of tumor recurrence at the last follow-up examination.

The authors present a patient who had prostatic carcinoma metastatic to the epididymis. The patient was asymptomatic except for painless swelling in the right epididymis. The laboratory radiographic and physical examination of the patient were normal. The prostate was clearly demarcated, homogeneous and solid. Surgery was performed in two stages. In the first stage semi-castration was performed. Histopathological analysis of the biopsy material showed prostatic carcinoma metastatic to the epididymis. There were no metastases in the testis. In the second stage, TUR of the prostate was performed. To our knowledge prostatic carcinoma metastatic to the epididymis has not been described previously.

A 77-year-old male was admitted to our department with the chief complaint of positive occult blood in urine on July 30, 1984. Endoscopically, we found a dark red tumor on the left posterior wall of the urinary bladder, which seemed to have coagula covering it. On August 31, transurethral resection of the bladder tumor (TUR-Bt) was performed, and the pathological interpretation was malignant melanoma. Dermatologically and ophthalmologically, we could not found the primary foci. A month later, cystoscopy demonstrated multiple blue black spots consistent with diffuse melanoma of the bladder. On May 7, 1985, he was admitted to our clinic with right hypochondralgia. On physical examination, the liver was palpable with an irregular surface, and the echogram showed multiple metastasis in the liver. TUR-Bt was carried out again, on May 17, 1985. Ultrastructually resected specimens demonstrated a lot of mature melanosomes in the tumor cells. The course of the patient progressively worsened, and he died on May 30, 1985. At autopsy, we found metastases in the central nervous system, bone, genitourinary tract, gastrointestinal tract and other organs. The left eye ball, which had been diagnosed as ophthalmomalacia by glaucoma six years earlier, was filled by a melanoma mass, and it seemed to be the primary foci.
