Breast metastases of prostatic carcinoma: immunohistochemical case study.

A breast mass developed in a patient receiving estrogen therapy for prostatic cancer. The prostate tumor was adenocarcinoma of small acinar type, whereas that of the breast was infiltrating medullary adenocarcinoma. Histological features of the two tumors differed and double cancer was suspected by conventional pathological study. However, immunohistochemical staining with prostatic specific antigen and prostatic acid phosphatase was positive in each tumor. These results indicate the breast tumor to be a metastasis from the prostatic cancer.

Immunohistological study of two malignant lymphomas found as testicular tumors.

Immunohistological studies of two testicular lymphomas are reported. In the first case, lymphoma cells bear T-cell markers such as Leu-4 and Leu-3a, while they do not react with antibodies against B-cell markers such as anti-Leu-14. In the second case, lymphoma cells do not react with anti-T or anti-B cell antibodies, but react with antibodies against B-4, OKT9, and C 13 (anti-HLA-DR). Thus, it is shown that the first case is a lymphoma of helper/inducer T-cell origin and the second case is a pre-B-cell or pre-pre-B-cell lymphoma.

[Antiemetic effects of MS-5080 associated with cisplatin chemotherapy--an attempt in assessment based on the sample score system using multivariate analysis].

Effect of a new antiemetic drug, MS-5080 was evaluated against nausea and vomiting induced by chemotherapy including cisplatin. Fifty patients with various urological malignancies were registered into this study, which were distributed to the aliquot number with a respective dose schedule of 2, 3, 4 and 5 mg/kg body weight of MS-5080. Forty-seven patients with a total of 73 chemotherapeutic courses were eligible for evaluation of antiemetic efficacy, whereas the side effect of MS-5080 were evaluated in 48 patients with a total of 74 courses. Antiemetic efficacy was evaluated in terms of duration of nausea, duration of vomiting, duration of food intolerance, and the number of vomiting episodes. No statistically significant difference was observed in relation to the dose dependency of MS-5080. In assessment of the side effects, a relatively high incidence of diarrhea was observed compared to the other known antiemetic drugs. In the present study, we attempted an evaluation based on the sample score system using multivariate analysis. The results were correlated well with results of a grading system of efficacy that were determined by each physician who treated the patients.

Inverted papillary carcinoma of the urinary bladder.

A 47-year-old man presented with an inverted papillary carcinoma of the urinary bladder. Cystoscopy revealed an approximately 2 cm mass, with a small stalk and smooth surface, which was situated just medial to the right ureteral orifice. Transurethral resection of the tumor was performed on July 25, 1983. Malignant changes were recognized in the epithelial cords in the resected specimen. This is in contrast to the general view that inverted papilloma of the urinary bladder is benign in nature. The authors believe that careful pathologic examination should be done when an inverted type tumor of the urinary tracts is found. No recurrence has been recognized as of September 11, 1987.

[Effects of etretinate on spermatogenesis and endocrine parameter function in man].

Nine adult men with psoriasis were treated orally with 50-75 mg/day aromatic retinoid, etretinate for more than 3 months. Semen analyses as well as measurement of serum levels of LH, FSH, prolactin, testosterone and estradiol were performed before and every month during the therapy for 3 months or more in order to study the effects of the drug on male reproductive function. Average sperm concentration at 2 months after the treatment by the drug was higher than the untreated value, although this was statistically not significant due to greater variations. Decrease in sperm count during the therapy was observed only in one patient. Sperm concentration of this case, however, was recovered and increased to higher levels after 6 months on the drug. No change was found in other semen parameters including sperm morphology. All hormone levels remained unchanged except for prolactin which increased. We conclude that etretinate did not cause suppression of spermatogenesis nor impairment of sperm motility or morphology as far as shown by the present observation periods.

[Multiple imaging procedures including MRI in bladder cancer].

Endoscopic photography, double contrast cystography, transurethral echography, X-ray CT scan, and MRI (magnetic resonance imaging) were utilized for the staging diagnosis of the four patients with carcinoma of the bladder. In the first case, a 70-year-old man, since all of the five imaging procedures suggested a superficial and pedunculated tumor, his bladder cancer was considered T1. The classification of stage T3 carcinoma was made for the second 86-year-old male. Because all of his imaging examinations showed a tumor infiltrating deep muscle and penetrating the bladder wall. The third case was a 36-year-old male. His clinical stage was diagnosed as T2 or T3a by cystophotography, double contrast cystogram, ultrasonography, and X-ray CT scan. However, MRI showed only thickened bladder wall and the infiltrating tumor could not be distinguished from the hypertrophic wall. The last patient, a 85-year-old female, had a smaller Ta cancer. Her double contrast cystography revealed the small tumor at the lateral bladder wall. But, the tumor could not be detected by transaxial, sagittal and coronal scans. Multiple imaging procedures combining MRI and staging diagnosis of the bladder carcinoma were discussed.

[Synchronously diagnosed and treated triple cancer (rectum-ureter-prostate)].

A 63-year-old man was admitted for examination of a rectal tumor. A stony hard nodule was palpated in his swollen prostate by rectal examination. The biopsies proved rectal and prostate carcinoma. Transabdominal echogram and DIP showed left hydronephrosis. Left ureteral cancer was suggested by the typical "goblet sign" with retrograde ureterography. Rectal lower anterior resection, left total nephroureterectomy with partial cystectomy, castration and pelvic lymphadenectomy were undertaken synchronously. The pathohistological diagnosis was triple cancer consisting of rectal mucotubular adenocarcinoma, prostatic carcinoma and ureteral transitional cell carcinoma. The diagnosis and treatment of the triple cancer were discussed.

[Changes in renal function on response to rapid administration of cisplatinum].

Seven patients with urologic carcinomas were examined for changes in renal function as a result of administration of Cisplatinum (CDDP) at a high rate of 50 or 100 mg/m2 within 5 hours, superimposing 2 liters of fluid before and after the CDDP dose, and the results were compared with the pretreatment values. Renal function tests revealed that BUN was elevated to 20 mg/dl or more in 5 but not beyond 30 mg/dl in any of the patients, that serum creatinine was elevated to 1.4 mg/dl or more in 3 cases with a maximum of 1.5 mg/dl, and that Ccr was decreased to less than 70% of the pretreatment value in 3 patients. These manifestations of imparied renal function were all transient and reversible, being mostly restored to the pretreatment values during or within 1 month after the end of CDDP treatment, and did not necessitate the discontinuation of the treatment in any patients. The above findings proved the rapid infusion of CDDP to be as safe in terms of renal function as prolonged, continued i.v. infusion of the drug, which would these fore make CDDP treatment of outpatients possible.

Childbirth in true hermaphrodite.

14-year-old Japanese girl with a 46,XX karyotype underwent an exploratory laparotomy for signs of virilization. The left ovary and other pelvic organs were of female type. The right gonad was found to be an ovotestis which was removed. At age of 25, the patient gave birth to a normal male infant by full-term, vaginal delivery. In the literature, this is the third case of normal delivery in 7 true hermaphrodites with pregnancy and childbirth.

Effect of different passage histories of infectious bronchitis virus on the sensitivity to inhibitors in chick serum and their removal by trypsin.

Sensitivity of the Beaudette strain of infectious bronchitis virus (IBV) to non-antibody inhibitors in neutralization tests depended on the passage history of the virus. The chick embryo kidney cell-adapted (E71 CEK11) virus was the most sensitive, but after one chick embryo (CE) passage (E71 CEK11 E1), this virus showed reversion to the sensitivity of the parent virus (E71). IBV inhibitors in chicken serum could be removed by treatment with trypsin but not with phospholipase C.

Human chorionic gonadotropin detected in urinary concentrates from patients with malignant tumors of the testis, prostate, bladder, ureter and kidney.

Human chorionic gonadotropin levels in concentrated 24-hour urine and serum were determined by a specific radioimmunoassay of beta-human chorionic gonadotropin in 47 patients with genitourinary carcinoma. Elevated human chorionic gonadotropin levels in urine were observed in 6 of 8 patients with active testicular tumor, 3 of 14 with prostatic cancer, 2 of 10 with bladder cancer, 1 of 2 with ureteral or renal pelvic tumors and 2 of 6 with renal cancer. Of the 14 patients with positive urinary human chorionic gonadotropin 4 had undetectable human chorionic gonadotropin levels in the serum. The tumors of all 8 patients with nontesticular cancer who had increased urinary human chorionic gonadotropin levels were in an advanced clinical stage or of poor histological differentiation. Our results suggest that some nontrophoblastic carcinomas of the genitourinary system are capable of ectopic production of human chorionic gonadotropin, particularly if the malignancy is advanced or poorly differentiated. The radioimmunoassay of beta-human chorionic gonadotropin in concentrated 24-hour urine specimens enhances the sensitivity of detection of ectopic human chorionic gonadotropin production.

Responses of serum testosterone levels to human chorionic gonadotrophin stimulation in patients with Klinefelter's syndrome after long-term androgen replacement therapy.

Responses of serum testosterone levels to repeated daily injections of 5000 IU hCG for 4 days were studied in 24 patients with Klinefelter's syndrome. Eighteen patients were untreated, and 8 had been given previous treatment with depot testosterone 100 mg intramuscularly every 2-3 weeks for an average duration of 4.7 years. Among them, 4 patients were examined both before and after the therapy. The hCG test was performed at least 2 weeks (0.5-12 months) after the last injection of depot testosterone in the treated patients. Mean basal testosterone level of the treated patients, 139 +/- 98 ng/dl (Mean +/- SD), was not significantly different from that of the untreated patients, 172 +/- 110 ng/dl. Maximum stimulated testosterone level in the treated patients, 170 +/- 107 ng/dl (P less than 0.05). These results suggest that long-term androgen administration may decrease the functional reserve of Leydig cells in patients with Klinefelter's syndrome.

Stricture of the anterior urethra following estrogen therapy in patients with prostatic cancer.

A high incidence of urethral strictures was noted in patients with prostatic cancer who were treated by antiandrogen therapy. Retrograde urethrograms showed urethral stricture in 24 of 42 patients (57%) after or during the therapy, despite the fact that no stricture was found before initiation of therapy. The stricture was long and the entire penile urethra was narrowed, associated with more severely constricted portions. All of the patients with urethral stricture had received estrogens, while none of the patients who had undergone castration alone or had not received any therapy showed a stricture. The strictures disappeared after the cessation of estrogen administration. These results indicate that estrogen administration induces stricture in the male anterior urethra. It is suggested that large amounts of estrogen cause atrophy and fibrosis of the spongy and cavernous bodies of the penis, depriving the urethra of its normal elasticity, which results in urethral stricture. The stricture is one of the complications of estrogen therapy for cancer of the prostate.
