    Notes: Basic fibroblast growth factor (FGF-2) is not only a potent mitogen for various cells but also a multifunctional factor with angiogenic and chemotactic activity, and the capacity to induce the synthesis of various proteinases and to modulate endocrine function. To clarify the role played by FGF-2 in the progression of pituitary tumor, we fused rat FGF-2 cDNA to the promoter SRα, consisting of the early promoter of SV40 and HTLV(I)-LTR, and we cotransfected GH3 cells with pSV2-neo by an electroporation method. After selection by G418, we obtained 7 neomycin-resistant clones. Southern blot analysis of genomic DNA revealed the presence of transfected rat FGF-2 cDNA in 4 of the 7 clones. To measure FGF-2 molecules, we established a new immuno-fluorometric assay system, using 3 monoclonal antibodies against different portions of human FGF-2. This assay had a minimum sensitivity of 10 pg/ml and cross-reacted neither with acidic fibroblast growth factor (FGF-1) nor insulin-like growth factor 1 (IGF-1), even at a concentration of 100 ng/ml. Although FGF-2 was undetectable in the culture medium of any of the clones, the cell homogenate contained a significant amount of FGF-2 (7.2 ng/mg protein) in 1 of the 4 FGF-2-transfected clones (GH3FGF(+)), whereas FGF-2 was not detected (〈5.2 pg/mg protein) in the cell homogenates of either the parent GH3 cells or the control cells transfected with pSV2-neo alone (GH3FGF(−)). GH3FGF(+) grew as adherent cells and formed epithelial sheets with a growth rate similar to that of control cells. The amount of prolactin(PRL) released by TRH was greater in GH3FGF(+) than that in GH3 or GH3FGF(−). On the other hand, the sensitivity to SRIF was increased in GH3FGF(+) compared with that in other clones. The findings of these in vitro studies indicate that FGF-2, if it is expressed in pituitary tumor cells, plays little if any role in cell growth but may modulate certain cell functions such as responsiveness to hormones.

    Notes: Background The advent of cisplatin rendered disseminated testicular germ cell tumor an often curable malignant disease. Patients with a heavy metastatic burden, however, remain poor risks; furthermore, many patients experience nausea or other adverse events. This paper reports a trial of a cisplatin-based (COMPE) combination chemotherapy regimen based on synchronization theory. Methods Twenty patients with disseminated germ cell testicular tumors were treated with COMPE; any residual tumor mass was surgically resected. Results Seventeen patients (85%) achieved complete remission by chemotherapy. The actuarial overall and cause-specific 3-year survival rates were 89% and 94%, respectively. In the subset of 16 “good-risk” patients, all remain alive after a median follow-up of 43 months. Complications were quite tolerable, with nephrotoxicity in particular being extremely mild. Conclusion COMPE is an effective chemotherapy regimen in patients with disseminated germ cell testicular tumors. Complications arising from this therapy are mild.

    Notes: Background: Intravesical bacillus Calmette-Guérin (BCC) therapy for superficial bladder cancer induces obvious local immunological responses. The purpose of this study was to examine the systemic immunological influences induced by intravesical BCG therapy. Methods: We measured peripheral blood lymphocyte subsets (PBLS) and monocyte counts in 30 patients with superficial bladder carcinoma by two-colored flow cytometry before, during, and after intravesical BCG treatment. Comparisons were made between 24 good treatment responders and 6 poor responders. Results: From 3 to 12 months after the beginning of treatment, PBLS and monocyte counts changed, as evidenced by an increase of suppressor T cells and a decrease of helper T cells. The good responders had higher cell counts than the poor responders, with differences in cell counts between good and poor responders more marked 1 month after beginning treatment, particularly of natural killer cells, cytotoxic T cells, and inducer T cells. These differences disappeared 3 months after the onset of treatment. Conclusion: Intravesical BCG therapy caused a marked and persistent alteration of the systemic immunological status.

    Notes: Introduction : We report a case of recurrence of sigmoid colon cancer in the residual urethra after cysto-prostato-sigmoidectomy. Methods/Results : The patient successfully underwent urethrectomy and is currently tumor-free. To our knowledge, this is the first case of recurrence of a non-urothelial malignant tumor in the residual urethra.

    Long-term Results of Definitive Treatment in Elderly Patients with Localized Prostate Cancer (1998)

    Notes: Background: The indication and effectiveness of definitive local treatment for prostate cancer in patients with a limited life expectancy remains to be established. This study is a retrospective analysis of the long-term clinical outcome of elderly patients with localized prostate cancer treated by radiotherapy or a radical prostatectomy. Methods: From 1982 to 1992, 37 patients with localized prostate cancer, aged 70 years or older, were treated initially by a pelvic lymphadenectomy and then with either external radiotherapy (n = 1 7) or a radical retropubic prostatectomy (n = 20). Lymph node metastasis was negative in all the cases, and no patients received hormonal treatment after the lymphadenectomy. The outcome of all patients was evaluated in June 1997. Results: The 10-year overall and relative survival rates for the radiotherapy group were 27% and 85%, which were not significantly different from the rates of patients in the prostatectomy group (38% and 74%, respectively). The 5-year progression free rates for the radiotherapy group and the prostatectomy group were 63% and 95%, respectively (P= 0.06). Conclusion: In elderly patients with localized prostate cancer, the superiority of a radical prostatectomy over radiotherapy was not demonstrated in terms of either overall or relative survival rates, although the progression rate tended to be higher in patients in the radiotherapy group. The indication of definitive treatment in elderly patients should be further studied incorporating a quality of life assessment.

    Notes: Background: Pelvic lymph node dissection (PLND) is an important staging method for men with clinically localized prostate cancer. We report our experience with staging PLND and the impact of lymph node metastasis on long-term prognosis.Methods: One hundred forty-eight consecutive patients who underwent staging PLND for clinically localized prostate cancer were retrospectively studied. Patients were evaluated for the presence and number of lymph node metastases, treatment (prostatectomy vs. radiotherapy), and endocrine therapy, and analyzed with respect to disease progression and survival. The mean follow-up period was 52.9 months (range, 2.3 to 165.8 months).Results: Thirty-two patients (21.6%) had pelvic lymph node metastases, the incidence of which markedly decreased from 32.3% in 1982 to 1987 to 6.7% in 1994 to 1997. The intervals to disease progression and cancer death were significantly shorter in patients with positive lymph nodes (P 〈 0.001). In stage D1 disease, patients who underwent a radical prostatectomy tended to be free of progression longer than those receiving radiotherapy or conservative therapy (P= 0.0546). Other factors, such as early endocrine therapy, the extent of lymph node involvement and the Gleason score of the primary tumor did not predict disease progression or survival.Conclusion: These data suggest a decreasing trend in the incidence of lymph node metastasis in the PSA era. Although longer disease-free intervals were observed in radical prostatectomy-treated patients, the impact of an aggressive approach to stage D1 disease awaits further studies.

    Notes: It is generally believed that signet-ring cell carcinoma (SRCC) of the prostate is a high-grade neoplasm with a poor prognosis. We report a case of a long-term survivor diagnosed with localized prostatic SRCC (T3N0M0), who has been alive without any clinical evidence of disease for 100 months after combination therapy which consisted of local irradiation and hormone administration. A posttreatment needle biopsy confirmed the pathological complete response.

    Notes: A case of pure bilateral renal tell carcinoma (RCC) in a 21-year-old female diagnosed as having tuberous selerosis is reported. She underwent a left nephrectomv because of her loss of appetite possibly caused by the tumor compressing her intestines. The preoperalive CI scan showed the presence of adipose tissue in bilateral renal tumors, which is highly suggestive of angiomvolipoma (AML). Histological examination, however, revealed no area or component ot the tumor with features characteristic of AML.
