[Chemotherapy of urothelial cancer with vincristine, mitomycin C, bleomycin, tegafur and OK-432].

A total of 24 patients with urothelial cancer were treated with a combination chemotherapy consisting of vincristine (1 mg, i.v., day 1), bleomycin (15 mg, or peplomycin, 10 mg, i.m. day 2), mitomycin-C (4 mg, i.v. day 3), tegafur (600-750 mg, p.o., every day) and OK-432 (2-4 KE, i.m., day 1, 3, 5). This one-week course was repeated for an average of 4.6 courses. Of these cases, 13 patients with early stage treated as adjuvant chemotherapy after radical operation showed strong suppressive effects against tumor recurrence or metastasis except 3 cases. However, in advanced cancer this regimen was less effective. Therefore, we modified this regimen: VCR 2mg and PEP, 10 mg on days 2, 4 and 6. This modified regimen was given to two patients and one showed partial response and I-A according to Karnofsky's criteria. Mild side effects such as slight leukopenia, fever up, gastrointestinal symptoms or alopecia were observed. These results suggest that this regimen could be used as an adjuvant chemotherapy after radical operation of urothelial malignancy for the purpose of protecting tumor recurrence or metastasis.

Immunologic markers and the diagnosis of prostatic cancer.

The authors review recent developments in the immunodiagnosis of prostatic cancer. Monoclonal antibodies to prostatic acid phosphatase, prostate-specific antigen, and several human prostate and prostate-cancer-related components are available. Prostatic acid phosphatase and prostatic antigen assays are still the only immunologic tools with clinical applications.

[A case of perirenal encysted hematoma secondary to renal cell adenocarcinoma].

Herein we report a case of perirenal encysted hematoma secondary to renal cell adenocarcinoma. A 57-year-old woman was hospitalized because of a palpable mass in the left flank. She had had an episode of left flank pain. X-ray studies demonstrated a tumor in the left kidney and a large cystic mass beneath the left kidney. The cyst was excised by nephrectomy. Histological examination of the large cyst revealed perirenal encysted hematoma secondary to renal cell adenocarcinoma. Six months postoperatively, she is now free from left lumbar pain, and alive with lung and liver metastasis.

[A case of giant prostate cancer].

A 67-year-old patient with stage C giant prostate cancer was treated with a combination of endocrine administration and chemotherapy. After administration of diethylstilbestrol diphosphate (250 mg/D, 16 days), bilateral orchiectomy and subsequent CDDP administration (30 mg/D X 5 days, e. 3 weeks, 4 courses), the primary tumor was reduced by about 90%. Clinical response was evaluated as partial response. Serum acid phosphatase activity, prostatic acid phosphatase, prostate antigen and nuclear DNA histogram served as useful tumor markers and changed in parallel to clinical course.

[Detection of circulating immune complexes by polyethyleneglycol precipitations complement consumption test in urological malignant diseases].

Circulating immune complexes (CIC) were detected and quantitated in 49 patients with urological malignant diseases (9 cases of renal cell cancer, 3 cases of renal pelvic and ureter cancer, 21 cases of bladder cancer and 16 cases of prostatic cancer), 9 patients with urological benign diseases and in normal subjects by the polyethylene-glycol precipitation complement consumption test (PEG-CC test). The average CIC level was 2.7 +/- 3.0% in 18 normal subjects and the normal range was less than 10% of the CIC level. CIC level of patients with renal cell cancer was 14.3 +/- 20.1%, being elevated in 3 of the 9 patients, that of patients with renal pelvic and ureter cancer was 4.7 +/- 4.6%, being within the normal range in 3 cases, that of patients with bladder cancer was 4.7 +/- 4.4%, being elevated in 1 of 21 patients, and that of patients with prostatic cancer was 8.9 +/- 15.4%, being elevated in 3 of 16 patients. In urological malignant diseases such as renal cell cancer and prostatic cancer the CIC values were relatively high.

A case report of renal pelvic squamous cell carcinoma.

We describe a case of a 75-year-old woman with squamous cell carcinoma in the right renal pelvis accompanied by multiple dysplasia in the upper urinary tract. Though it is difficult to make a preoperative diagnosis of squamous cell carcinoma, lavage cytology is particularly valuable. Renal arteriography and cross-sectional imaging are also useful to assess an accurate stage. We postulate that severe dysplasia could be a precursor of squamous cell carcinoma as well as transitional cell carcinoma.

Anterior pituitary, thyroid, parathyroid and adrenal responses to subtotal thyroidectomy in patients with Graves' disease.

Changes in the serum levels of anterior pituitary, thyroid, parathyroid, and adrenal hormones following subtotal thyroidectomy in 31 patients with Graves' disease were investigated. In 14 patients, rapid ACTH tests were performed on the preoperative and the first, third, and seventh post-operative days. Remarkable differences were not seen with regard to the changes in anterior pituitary hormones or cortisol, compared to those seen during general surgery. As to the thyroid hormones, the serum level of triiodothyronine (T3) decreased markedly after surgery and fell to half that of the preoperative value on the first postoperative day. Thereafter, a low value of T3 was maintained during the early postoperative period. Unlike T3, the serum level of thyroxine (T4) decreased gradually until the 7th post-operative day. The levels of both epinephrine and norepinephrine increased transiently during surgery, but the serum level of norepinephrine increased again on the third postoperative day. In the postoperative period, almost half the number of patients showed an inadequate cortisol response to rapid ACTH tests. It is suggested that the unique responses, such as the rise in serum norepinephrine or an inadequate response of cortisol to ACTH, or hypocalcemia, after subtotal thyroidectomy in patients with Graves' disease is largely due to the rapid decrease of T3 in the hypothyroid state, as was noted during the postoperative period.
