We assessed the frequency of bone metastases, their association with serum alkaline phosphatase (AP), and prognostic capabilities of AP in patients with renal cell carcinoma (RCC), using bone scan as the reference standard for diagnosis.We conducted a retrospective review of patients with metastatic RCC treated with either autologous ex vivo activated T-lymphocytes and cimetidine (ALT) or cimetidine alone.Twenty-eight of 90 patients (31%) had evidence of bone metastases by bone scan. With 100 mg/ dL as the upper limit of normal, 11 of 28 (39%) patients with bone metastases had normal AP levels. Of these 11 patients, 8 had bone pain. Of the 3 asymptomatic patients with bone metastasis and normal AP levels, only 1 had bone as the only site of metastasis and would have been incorrectly staged without the scan. Patients with bone metastases had a significantly shorter median survival than those without bone metastases (13.8 versus 25.3 months; P0.05). Among patients without bone metastases who had elevated AP levels, those treated with ALT had significantly longer median survivals than those treated with cimetidine alone (27.6 versus 14.5 months; P0.05). Overall, patients treated with ALT had a significantly longer median survival than the ones treated only with cimetidine (21 versus 8.5 months; P0.05). Overall, the median survival for patients with elevated AP levels (10 months) was not significantly different from that of those with normal AP levels (13 months).In a high-risk group of patients with metastatic RCC, 31% had bone metastases. Elevated AP levels, the presence of bone pain, or the presence of other metastases correctly predicted bone metastasis in all but 1 patient. A bone scan may safely be omitted in patients with RCC, normal AP levels, and no bone pain. However, AP elevation itself had little prognostic capability in these patients.

Objective . To examine the efficacy of prostate-specific antigen (PSA) density (PSAD; serum PSA/prostate volume) as a predictor of clinical outcome of patients undergoing radical retropubic prostatectomy for clinically confined prostate cancer, and its ability to determine the presence of micrometastatic disease. Methods. A retrospective analysis of patient outcome as reflected by surgical stage and postoperative PSA was performed with respect to PSAD as determined by preoperative PSA and pathologic prostate gland volume. The findings for 107 consecutive patients who underwent radical prostatectomy are reported. Results. PSAD at low values was found to be 90 percent accurate in predicting operative success or absence of micrometastatic disease. PSAD at high values was shown to be 70 percent accurate in predicting failure. Conclusions. PSAD appears to be useful in selecting patients for radical prostatectomy and may be capable of identifying patients with micrometastatic disease.

Objectives Incontinence after radical retropubic prostatectomy remains a common problem. This study determines the efficacy of a tubularized bladder neck reconstruction for improving the time to continence and also the total rate of continence following radical retropubic prostatectomy. Methods Tubularized bladder neck reconstruction was performed in 29 patients by creating a trapezoidalshaped anterior bladder flap and performing tubularization over a 30 F red rubber catheter prior to urethrovesical anastomosis. This flap measured approximately 5 cm at its base and 3 cm at its apex. Continence rates of these patients were compared to results of 30 randomly selected patients in whom a bladder flap was not used. Results Seven of 29 (24%) patients with tubularized bladder neck reconstruction were fully continent within 24 hours of catheter removal and 27 of 29 (93%) were fully continent by 3 months follow-up. An additional patient was continent at 6 months for a total continence rate of 28 of 29 (97%). These continence rates were significantly higher at all follow-up times than for patients in whom an anterior bladder flap was not used. One patient developed a bladder neck contracture and was successfully managed with visual urethrotomy. He is fully continent. Conclusions Tubularized bladder neck reconstruction following radical prostatectomy may both increase the successful achievement of postoperative continence and decrease the time needed to achieve full continence without increasing morbidity.

A testicular tumor presenting as torsion is reported in a fifty-two-year-old man. This is the first reported case in a patient more than twenty-eight years old.
