Feedback microwave thermotherapy with the ProstaLund Compact Device for obstructive benign prostatic hyperplasia: 12-month response rates and complications.

PURPOSE: To evaluate the effectiveness of the ProstaLund Compact Device in the treatment of benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: A series of 38 consecutive patients with a mean age of 72.6+/-8.2 years, 19 with an indwelling catheter, underwent transurethral microwave thermotherapy (TUMT) with the ProstaLund Compact Device. Pretreatment evaluation included transrectal ultrasonography (TRUS), urodynamics, and cystoscopy for all patients and flow rate (Qmax), postvoiding residual urine volume (PVR), International Prostate Symptom Score (IPSS), and quality-of-life (QoL) assessment for those without a catheter. The mean prostate volume was 63.5+/-30 cc. The Qmax, IPSS, and QoL studies were repeated at 3, 6, and 12 months, while urodynamics, cystoscopy, and TRUS were repeated at 6 and 12 months. RESULTS: The treatment lasted a mean of 43.1+/-17.1 minutes, achieved a maximal intraprostatic temperature of 58.7+/-7.2 degrees C, and destroyed 18.4+/-14.3 g of prostatic tissue. Twelve months post-treatment, for the patients without a catheter preoperatively, the IPSS was improved from 21.5+/-6.3 to 6.5+/-3.1 (P<0.001), Qmax from 7.2+/-3.1 mL/sec to 18.1+/-7.4 mL/sec (P<0.001), detrusor pressure at Qmax from 87.5+/-15 cm H2O to 48.4+/-16.4 cm H2O (P<0.001), and PVR from 113.2+/-78.2 mL to 34.6+/-36.7 mL (P<0.01). The good-response rates for IPSS (or=50% improvement), Qmax (>or=15 mL/sec or >or=50% improvement), PVR (<50 mL or >or=50% decrease), and QoL (

Oral estramustine and oral etoposide for hormone-refractory prostate cancer.

OBJECTIVES: Estramustine and etoposide have been shown to inhibit the growth of prostate cancer cells in experimental models. An in vivo synergism of the two agents, when administered to patients with metastatic prostate cancer refractory to hormone therapy, has been reported. To confirm these results, we administered this combination to a large number of patients with hormone-refractory prostate cancer (HRPC). METHODS: Fifty-six patients with metastatic HRPC were treated with oral estramustine 140 mg three times a day and oral etoposide 50 mg/m2/day for 21 days. Therapy was discontinued for 7 days and the cycle was then repeated. Therapy was continued until evidence of disease progression or unacceptable toxicity occurred. To control for the possible interference of an antiandrogen withdrawal effect, all patients discontinued antiandrogen therapy and were not enrolled in the study unless there was evidence of disease progression. RESULTS: Forty-five percent of 33 patients with measurable soft tissue disease demonstrated an objective response, which included five complete and ten partial responses. Among 52 patients with osseous disease 17% showed improvement and 50% showed stability of bone scan. Thirty patients (58%) demonstrated a decrease of more than 50% in pretreatment prostate-specific antigen (PSA) levels. The median survival of all patients was 13 months. Good pretreatment performance status, measurable disease response, improvement or stability of bone scan, and PSA response were important predictors of longer survival. CONCLUSIONS: We conclude that the combination of estramustine and etoposide is an active and well-tolerated oral regimen in HRPC.

Chemotherapy with methotrexate, vinblastine, epirubicin and carboplatin (Carbo-MVE) in transitional cell urothelial cancer. A Hellenic Co-Operative Oncology Group study.

OBJECTIVES: We conducted a phase II study in order to assess the efficacy and toxicity of Carbo-MVE (carboplatin 250 mg/m2 i.v. day 1, methotrexate 25 mg/m2 i.v. days 1, 15 and 22, vinblastine 2.5 mg/m2 i.v. days 1, 15 and 22 and epirubicin 25 mg/m2 day 1). The regimen ws to be repeated every 28 days. METHODS: Forty-six patients with transitional cell carcinoma of the bladder entered the study. Patients with metastatic disease were treated for 6 cycles, while patients with locally advanced or locoregional disease had 4 cycles of induction chemotherapy followed by cystectomy or radiotherapy. RESULTS: Toxicity was generally mild and treatment well tolerated. The overall response rate was 54.4%, with 26% complete and 28.3% partial response rates. The median survival was 17.5 months with the complete responders to live significantly longer (64.82 months) than those who had a partial response (20.5 months), stable disease (15 months) or progressive disease (8.5 months). Survival was also significantly longer in patients with good performance status as well as in patients with locally advanced or locoregional disease. Finally, patients who had cystectomy as definitive treatment survived significantly longer (32 months) than those who had been irradiated (16 months). CONCLUSIONS: The Carbo-MVE regimen appears to be an effective and well-tolerated treatment in patients with transitional cell carcinoma of the bladder.

Carcinosarcoma of the bladder.

We present a case of carcinosarcoma of the bladder, the first in our experience. This tumour is generally considered to be a rare one, has uncertain aetiology and poor prognosis. At present, radical cystectomy is the treatment of choice.
