Oral estramustine and cyclophosphamide in patients with metastatic hormone refractory prostate carcinoma: a phase II study.

BACKGROUND: Nearly all cases of metastatic prostate carcinoma progress, after hormonal ablation, to a hormone refractory status. To the authors' knowledge no standard chemotherapy for patients with hormone refractory prostate carcinoma (HRPC) exists. In a prospective study, the efficacy and toxicity of an oral combination of estramustine and cyclophosphamide were evaluated. METHODS: Between March 1996 and April 1998, 32 consecutive patients (median age 74 years; range, 53-84 years) with metastatic HRPC were treated with oral estramustine (10 mg/kg/day) and oral cyclophosphamide (2 mg/kg/day) for 14 days every 28 days. Inclusion criteria were previous complete androgen blockade, antiandrogen withdrawal evaluation, and clinical or biochemical disease progression. Response assessment was based on a decrease > or =50% in the prostate specific antigen (PSA) level associated with improvement (or no worsening) in Eastern Cooperative Oncology Group (ECOG) performance status (PS) and relief of bone pain (if present). RESULTS: All patients were evaluable for efficacy and toxicity. PSA levels decreased by at least 50% in 14 patients (43.7%) (95% confidence interval, 26.5-60.9), remained stable in 12 patients (37.5%), and rose in 6 patients (18.8%). ECOG PS was 0 in 5 of 14 patients, improved from 1 to 0 in 7 patients, and remained unchanged in 2 patients. Bone pain, present in 8 of 14 patients, disappeared in 7 and was partially relieved in 1. The median duration of response was 30 weeks (range, 8-88+ weeks). An objective partial response was obtained in two cases. Toxicity was mild and mainly gastrointestinal (World Health Organization [WHO] Grade 1). No cases of WHO Grade 3-4 hematologic toxicity occurred. CONCLUSIONS: The oral combination of estramustine and cyclophosphamide appears to be safe and effective in patients with HRPC. In responding patients its use shows a clinical benefit in terms of improvement of ECOG PS and pain control.

Prostate cancer: correlation between local and systemic disease.

BACKGROUND: Prostate cancer is in Italian men the second neoplasm for incidence. Transrectal ultrasonography (TRUS) is still today a cheap test, not very invasive, well accepted by the motivated patient and sufficiently accurate for the valuation of the local status disease. We proposed our data to verify if a careful local ultrasonographic study of prostatic carcinoma could or not predict its systemic course. METHODS: We have valued 136 out patients affected by prostate cancer and treated with either palliative medical therapy or radiotherapy. The follow-up varies from 12 to 132 months. The local, evaluation of the disease done through TRUS in longitudinal and/or axial scan (the dimension of the gland, the volume and ultrasonographic characteristics of the lesion, capsular involvement and estimation of the surrounding structures: seminal vesicles, vesica, rectum). RESULTS: In the long run, considering the local and systemic course of the disease, we have noticed accordance globally in 116 patients (85.3%); 13 patients showed only systematic progression (9.5%) while in 7 patients, we have noticed a local but not a systemic variation. CONCLUSIONS: We can deduce that periodical carrying-out of the TRUS (twice a year) constitute a reliable index not only of local procedure of the pt. but also predicting the systemic course of the disease, making the routine carrying out of the other check-up unnecessary, that could be reserved for cases with precise clinical indication.

[Urethral diverticuli in women: role of diagnostic methods in the preoperative assessment]. / Diverticoli uretrali nella donna: ruolo delle metodiche diagnostiche nell'inquadramento preoperatorio.

From 1985 to 1993 we observed 9 female patients with urethral diverticula. All patients underwent first clinical examination and then US (suprapubic and transrectal or transvaginal scans) and X-ray cystography which demonstrated the communication between the diverticula and the urethra, MRI was also performed, in order to explain the rapports between the diverticulum and the sphyncter. All patients underwent surgery and 8 were cured. No cases of incontinence were observed.

[Locally advanced prostatic cancer and systemic involvement]. / Cancro prostatico localmente avanzato ed interessamento sistemico.

In a group of 115 patients with prostatic cancer, the correlation between the local and systemic evolution of the neoplasm has been evaluated. In 80 patients non local and systemic up-staging of the tumor was observed. In further 18 patients both local and systemic staging uppers and in the remaining 17 patients no correlation between local and systemic evolution was observed. In conclusion, in this series, the prostatic cancer demonstrated an high concordance in both local and systemic evolution and then the modifications of local staging can be used as a predictive parameter of systemic evolution of the prostatic cancer.

[Echographic features of testicular neoplasms. Our experience]. / Caratteri ecografici delle neoplasie testicolari. Nostra esperienza.

14 patients with primitive testicular cancer underwent US and afterwards surgery. A comparison between echo-pattern and hysto-pathology was done with the following results: sharp limits and ipoechoic homogeneous pattern in leydigioma and low-staging seminoma. Presence of anechoic areas and irregular limits: teratoma and embrionary carcinoma with no correlation with the staging. Inclusively no correlation between echo-pattern and staging of neoplasm or presence of neoplastic lymphnodes was observed.

[Role of ultrasonography in the follow-up of surgically treated patients. Upper urinary tract. Complications after conservative surgery]. / Ruolo dell'ecografia nel follow-up del paziente operato. Alto apparato urinario. Complicanze dopo chirurgia conservativa.

The Authors describe the purposes of ultrasonographic follow-up after both conservative surgery and endoscopic or endourological operations of the upper urinary tract. In these cases ultrasonography evaluates the results of normal surgery, the presence of early or late complications, and of iatrogenic lesions. The echo-patterns of deformations in the outline of the kidneys, of hematic, urinary or lymphatic collections (both retroperitoneal and intraperitoneal), of fistulas, of sclero-lipomatosis and of post-cicatrization hydronephrosis are described. The importance of evaluating the degree of obstruction by a dynamic ultrasonographic study with furosemide-test is emphasized. The ultrasonographic monitoring of urethral and pyelostomy setting of catheters is also described. The echo-patterns of retroperitoneal and intraperitoneal fluid collections and renal hematomas, in relation also the kind of fluid contained are widely discussed.
