Outcome of patients with localized prostate cancer treated by radiotherapy after confirming the absence of lymph node invasion.

Objective: Management of lymph nodes in radiotherapy for prostate cancer is an issue for curative intent. To find the influence of lymph nodes, patients with T1-T3 prostate cancer and surgically confirmed negative nodes were treated with radiotherapy.

Methods: After lymphadenectomy, 118 patients received photon beam radiotherapy with 66 Gy to the prostate.

PSA doubling time as a predictive factor on repeat biopsy for detection of prostate cancer.

Objective: Detection of prostate cancer needs a biopsy of the prostate. Suspecting cancer from an increase in prostate-specific antigen (PSA) has a high negative rate at an initial prostate biopsy. Cases with negative initial biopsy may be the candidates of subsequent biopsy.

[Primary carcinoid tumor of the testis metastatic to the para-aortic lymph nodes in six years after the first operation: a case report].

This is an additional report of a case which Kinsui, et al. reported in 2000. A primary testicular tumor metastasized to the para-aortic lymph node in 6 years after the first high orichietectomy.

Outcome of patients with hormone-refractory prostate cancer: prognostic significance of prostate-specific antigen-doubling time and nadir prostate-specific antigen.

Objective: Most patients with advanced prostate cancer after prostate-specific antigen (PSA) relapse following maximum androgen blockade rapidly progress to death. The present study was aimed to predict the survival of these serious patients after PSA relapse.

Methods: Sixty-eight patients with M1b and 20 patients with T3b, who relapsed and died of cancer within a short period, were studied.

Significance of prostate-specific antigen-doubling time on survival of patients with hormone refractory prostate cancer and bone metastasis: analysis on 56 cases of cancer-specific death.

Objective: Most of the metastatic diseases initially respond to maximum androgen blockade, but then relapse and lose response, and finally die. After relapse, the disease progresses in various courses. The present study was aimed to establish the predicting factors influencing the survival period of patients at prostate-specific antigen (PSA) relapse (entering the hormone refractory state).

Comparison of Gleason grade and score between preoperative biopsy and prostatectomy specimens in prostate cancer.

Aim: Although the histopathological findings obtained from biopsy specimens are important for choosing the appropriate management of prostate cancer, there have been some discrepancies in Gleason grade and consequently, score between biopsy and surgical specimens. A comparison of findings between these two kinds of specimens was performed.

Methods: Radical prostatectomy was performed at Asahi General Hospital on 223 cases of T1b-T3 without previous cancer treatment, and the Gleason grade and score of the biopsy and surgical specimens were compared.

Kidney stone disease and risk factors for coronary heart disease.

Background: We conducted a case-control study to examine the impact of coronal heart disease (CHD) risk factors on calcium oxalate (CaOX) stone formation.

Methods: Variables included body mass index (BMI), current alcohol use, smoking habit, hypertension, hypercholesterolemia, diabetes mellitus, and hyperuricemia. Data suf fi cient for analysis were obtained for 181 CaOX stone formers and 187 controls.
