Nb rat prostatic adenocarcinomas, previously induced by the administration of testosterone and estrogen, have been serially studied as heterotransplants into congenitally athymic (nude) mice and into groups of Nb rats. This animal system has been used to evaluate the chemotherapeutic efficacy of 5-fluorouracil and Ftorafur. The use of both species was to determine if there would be any significant difference in relative tumor growth in nude mice which lack functional T cells as opposed to intact Nb rats. The autonomous tumor, 102 Pr, is the subject of the thesis presented herein. One donor Nb rat bearing 102 Pr prostatic adenocarcinoma served as the donor for this experiment. The nude mice and Nb rats received the transplant on the same date and were subjected to the chemotherapies outlined above and were treated after there was sufficient increase in tumor volume from the 2 mm3 wedge to assure growth and neovascularity (greater than 60 mm3). Statistically significant data was presented revealing 5-fluorouracil to be efficacious in the treatment of these tumors. Also presented is data revealing differences in growth versus time in the respective recipient animal hosts. It is suggested herein that this combination animal model system could be used for screening potential cytotoxic chemotherapeutic agents.

A 58-year-old male complaining of pollakisuria, miction pain and back pain visited us Dec. 26, 1979. Rectal examination revealed the prostate enlarged by 5 digital width, stony hard and irregular. Transrectal needle biopsy revealed moderately differentiated adenocarcinoma of the prostate. Bladder neck invasion, pelvic and mediastinal lymph node metastases and multiple bone metastases were found. The case was diagnosed with prostatic adenocarcinoma T3N2M1 (OSS, LYM) stage D2. Three courses of chemotherapy using ifosfamide applied from Feb. 2, 1980 showed no marked effect except for partial pain relief. Hormonal treatment with diethylstilbestrol diphosphate was started from May 28 and arterial infusion chemotherapy using CDDP and 5-FU was performed 2 months later, resulting in size reduction of the prostate and pelvic lymph node metastases and disappearance of mediastinal lymph node metastases. Needle biopsy of the prostate was negative for cancer cells. After 8 months, Tegafur was started, and 12 months later radiotherapy was added to the prostate and pelvic lymph nodes. The abnormal accumulation in bone scan began to decrease after 14 months and achieved complete remission 28 months after the initial therapy. We discontinued the hormonal therapy 31 months later because of his complaint of chest discomfort and palpitation. At the present time, 14 years after the initial therapy, the prostate was 35 x 29 x 19 mm in size on transrectal ultrasonography with undetectable serum PSA level and no tumor cells but only mass fibrosis has been seen by pathological examinations. We considered this patient to be with no evidence of disease.
