          Abstract

          Herein we report a case of a squamous cell carcinoma of a well-healed suprapubic cystostomy tract scar involving the bladder mucosa in a 56-year-old man. He presented with a spontaneous suprapubic urinary leak from a suprapubic cystostomy tract scar. He had a history of urethral stricture and failed urethroplasty. Preoperative cystoscopy suggested a bladder mass. Transurethral biopsy of the bladder mass revealed a squamous cell carcinoma confined to the suprapubic cystostomy tract involving the bladder mucosa. The patient died 6 months after the start of radiation therapy after lung metastasis and pneumonia.

          Urinary system.

          Although site-specific cancer frequencies and incidence rates for the United States are regularly reported by the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) program, they have not been reported by histologic type within a specific site. This report presents data for 76,303 cancers of the urinary tract by histologic type. Cancer data were obtained from the SEER program. Urinary tract cancers were eligible if they were histologically confirmed, in situ or invasive, and diagnosed between 1973 and 1987. The urinary tract was divided into the following sites: kidney and renal pelvis, ureter, urinary bladder, urethra, and other urinary. Histologic types were evaluated by site, age, sex, race, incidence, and survival. Of the 76,303 cancers, 72.0% were transitional cell carcinomas and 22.0% were adenocarcinomas. Adenocarcinoma was the most common histologic type in the kidney and renal pelvis (also referred to as renal cell carcinoma), whereas transitional cell carcinoma was the most common histologic type in the remainder of the urinary tract. For the more common histologic types, age-adjusted incidence rates were always higher among males than females. Because adenocarcinomas represent most kidney and renal pelvis cancers and transitional cell carcinomas represent most urinary bladder cancers, these histologic types largely explain incidence and survival trends reported for these two common cancer sites. Future population-based cancer epidemiologic studies should try to focus more on specific histologic types within a cancer site to better clarify risk factors and incidence and survival trends for cancer.

            Epidemiological characteristics of squamous cell carcinoma and adenocarcinoma of the bladder.

            Recent incidence data from the United States indicate that transitional cell carcinoma accounts for the vast majority (95%) of bladder tumors in this country, with squamous cell carcinoma (less than 3%) and adenocarcinoma (less than 2%) comprising nearly all the remaining cases. Rates of squamous cell carcinoma and adenocarcinoma were higher in blacks compared to whites, while the reverse was true for transitional cell carcinoma. All three tumors predominated in males, especially transitional cell carcinoma. A population-based case-control study of bladder cancer conducted in 10 geographical areas of the United States identified 43 patients with squamous cell carcinoma and 32 with adenocarcinoma to permit an examination of risk factors. Cigarette smoking was significantly associated with risk of squamous cell carcinoma, with the relative risk rising to 6.1 among smokers of 40 or more cigarettes/day. Significantly elevated risks of squamous cell carcinoma were also associated with a history of 3 or more urinary tract infections (relative risk = 5.7) and with employment as welders and cooks. Risk factors were generally less conspicuous for adenocarcinoma, except for a significant trend with the amount of coffee drinking; however, this finding is based on small numbers and should be interpreted cautiously.

              Squamous cell carcinoma of the bladder.

              Clinical and morphological features of 90 cases of squamous cell carcinoma of the bladder have been reviewed. The lesions were solitary in 90 per cent of the patients, developed without a history of vesical malignant disease in 82 per cent and were invasive at the time of diagnosis in all cases. Ureteral obstruction was demonstrated in 42 per cent of the group. The over-all survival rate at 5 years was only 10.6 per cent. There were 17 patients who received no therapy, all of whom were dead before 2 years. Unassisted supervoltage radiation therapy for patients with stages B2 and C lesions yielded a 5-year survival rate only 17.7 per cent. However, preoperative radiotherapy followed by simple total cystectomy and urinary diversion in a small number of patients with stages B2 and C lesions resulted in a 5-year survival rate in excess of 34 per cent. We are encouraged by this finding and believe that combination therapy warrants further clinical trial.
