Six female beagle dogs were given a daily dose of 100 mg MOCA, by capsule, 3 days per week for the first 6 weeks and then 5 days per week continuously for periods up to 9.0 years. The dose varied from 8 to 15 mg/kg body weight/day among the dogs. Six female beagle dogs were kept as untreated controls. The test was terminated after 9.0 years of treatment. The average plasma glutamic-pyruvic transaminase activity of the dogs fed MOCA was higher than that of the controls during the first and last two years on test. During the eighth and ninth years the urine sediment from MOCA dogs contained excessive numbers of erythrocytes, leukocytes, and epithelial cells. Some epithelial cells contained abnormalities that suggested neoplasia in the genitourinary tract. One MOCA dog, sacrificed after 8.3 years on test was found to have a papillary transitional cell carcinoma of the urinary bladder. Of four MOCA dogs sacrificed after 9.0 years on test, three were found to have papillary transitional cell carcinomas of the urinary bladder and one had a combined transitional cell carcinoma and adenocarcinoma of the urethra. The urethral tumor had metastasized to the liver, but the papillary transitional cell carcinomas found in the other four dogs did not invade the muscle layers of the bladder wall and did not metastasize. Since no urinary bladder tumors were found in the six control dogs, MOCA was considered to be carcinogenic for the urinary bladder of dogs under the conditions employed (p less than 0.025, Fisher's Exact Test, one tail). Three of five MOCA dogs contained hyperplastic nodules in the liver with no such nodules in six control dogs (p greater than 0.05, Fisher's Exact Test, one tail). This was considered to be suggestive of an effect of MOCA treatment.

The effect of selenite coadministration on the toxicity and antitumor activity of repeated treatment with high doses of cis-diamminedichloroplatinum (cis-DDP) was examined in mice. Sodium selenite was injected s.c. into separate abdominal sites of mice together with cis-DDP at a molar ratio of 1:3.5 (selenite to cis-DDP) on day 0. The same amount of selenite was given daily for 4 subsequent days (days 1-4). This fixed administration schedule was repeated weekly for a total of 7 weeks. Under the experimental conditions used, the lethal toxicity, renal toxicity [indicated by an increase in blood urea nitrogen (BUN) and plasma creatinine levels], hepatic toxicity (indicated by an increase in plasma GPT and GOT activity), and myelotoxicity (indicated by a decrease in the numbers of leukocytes and platelets) observed in mice given repeated doses of cis-DDP alone (15 or 25 mumol/kg, s.c.) were significantly depressed by the coadministration of sodium selenite. Treatment with cis-DDP alone (15, 20, or 25 mumol/kg, s.c.) resulted in some dose-dependent prolongation of the life span of mice transplanted either s.c. with colon adenocarcinoma 38 (colon 38) or i.p. with P388 leukemia (P388) but did not completely depress the tumor growth, and the animals died of either progressive disease or cis-DDP-induced toxicity. However, following the coadministration of 7.1 mumol/kg selenite with 25 mumol/kg cis-DDP, all of the mice transplanted either s.c. with colon 38 or i.p. with P388 survived for as long as 4 months after the end of the treatment and showed no evidence of malignancy. These results indicate that selenite coadministration enables the use of increasing doses of cis-DDP and, consequently, enhances the antitumor effect of cis-DDP by depressing its side effects.

Carcinoma of the hepatic duct bifurcation was diagnosed in a 67-year-old women with obstructive jaundice. As metastatic spread could not be demonstrated the carcinoma was removed with a view of achieving a cure (hemihepatectomy, resection of the hepatic duct and the bifurcation, cholecystectomy and hepatojejunostomy). Histological examination indicated adenocarcinoma of the biliary tract. Seven months postoperatively the patient was found to be cachectic and cough up greenish liquid sputum. Bilirubin concentration in sputum was 500 mumol/l. There was no jaundice and total bilirubin concentration was 33 mumol/l. Alkaline phosphatase was 508 U/l, but GOT and GPT were normal (23 U/l and 21 U/l). Computed tomography confirmed the clinical diagnosis of a biliobronchial fistula. The patient died 9 days after renewed hospitalization of tumour cachexia. The biliobronchial fistula was found at necropsy.

The poor survival rate of patients with extrahepatic bile duct tumors is well documented. Over the course of 4 years, we treated a white woman with diabetes diagnosed with histologically proven adenocarcinoma of the common bile duct with six injections of dihematoporphyrin ether followed by seven photodynamic therapy treatments to the biliary duct. As of July 1989, the patient was still alive, was not jaundiced, and had a Karnofsky performance status of 70. No changes occurred in any blood chemistry value from the time of injection to the time of photodynamic therapy. Of the transient elevations of some blood chemistry values and the white blood cell count, which occurred within 24 to 48 hours after photodynamic therapy, only those of alanine aminotransferase, aspartate aminotransferase, and amylase were significant.

The aim of this study was to produce large liver tumors reliably, and to diagnose the tumors during development. Therefore, New Zealand white rabbits were treated with N-nitrosodiethylamine orally three times per week by gavage and were examined by clinical-chemical assay at regular intervals during the average treatment period of 14 months. The total cumulative dose was 1200 mg N-nitrosodiethylamine over 14 months. After a short treatment period the initial dose of 3 mg/kg had to be reduced to 1.5 mg/kg. In all 11 treated animals (100%) liver tumors were seen at the end of the study. Four control animals did not show any neoplastic changes. Clinical parameters investigated were for an assessment of liver function, total protein, urea, creatinine, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, albumin and neuraminic acid as well as some serum electrolytes. The in vivo diagnosis of liver tumors based on changes in these parameters proved to be relatively unreliable. The liver enzyme tests and urea concentration only yielded significant changes when the liver tumors were very large. Changes in neuraminic acid levels were the most reliable indicator for the presence of a liver tumor in this animal model. In the 11 treated animals, serum values of this marker increased towards the end of the study by an average of 300 mg/dl. The induced tumors were mainly hepatocellular carcinomas. Only in 1 animal was a hepatocellular adenoma found. Further primary tumors diagnosed were six adenomas in the kidneys and two uterus adenomas, as well as nasal cavity tumors (two papillomas, one carcinoma, one adenoma and one adenocarcinoma). In 70% of the treated rabbits the hepatocellular carcinomas had metastasized to the lungs.

A phase II study of bronchial artery infusion of mitomycin C (MMC) was performed in 14 patients with non-small cell lung cancer (6 patients with adenocarcinoma, 6 patients with squamous cell carcinoma and 2 patients with large cell carcinoma). MMC at a dose of 20 mg was infused into the bronchial artery (total dose 20-60 mg, mean 27 mg). Among the 14 patients, one with adenocarcinoma of the lung showed partial response. The response rate for bronchial artery infusion of MMC was thus 7.1%. The toxic effects included anemia (35.7%), leukopenia (28.6%), thrombopenia (14.3%), elevation of GPT (14.3%), anorexia (14.3%), nausea (7.1%) and eruption (7.1%).

Two IgG1 type monoclonal antibodies ALT-01 and ALT-04 were prepared by two different immunization schedules. ALT-01 was generated by fusing murine myeloma NS-1 cells with splenocytes from a BALB/c mouse immunized by human lung squamous carcinoma cells, which were coated by antisera to mixed human lymphocytes. For preparation of ALT-04, human lung squamous carcinoma xenograft-bearing nude mice were injected I. P. with the spleen cells of normal BALB/c mice in order to acquire immunofunction. The spleen cells from these tumor-bearing nude mice were fused with NS-1 cells. Then, these hybridomas were screened and cloned for 3 times. Two antibodies were shown to recognize the surface antigen on human lung carcinoma cells and several kinds of tumor cell lines but not those on normal cell lines. ALT-01 reacted to neither human lung carcinoma tissue nor its xenograft. ALT-04 reacted to human lung carcinoma tissue, of which, reaction to adenocarcinoma was the strongest but not to various normal tissues. Immunoprecipitation followed by SDS-polyacrylamide gel electrophoresis and autoradiography was used to detect the associated antigen in 35S-labeled human lung carcinoma cells. Antigens, reacting to ALT-01, show one band of Mr 38,000 but those to ALT-04 reveal two bands of Mr 48,000 and 36,000.

During the past three years we have entered 54 patients with gastric adenocarcinoma into a clinical trial of oral administration of injectable 5-fluorouracil (5-Fu). Of the 20 unresectable advanced cases, the median survival was 6.2 months, and for 34 resectable ones, median survival was 22 months. These results were comparable to those reported in the literature. It is also safe, easy to administer, well tolerated, and does not have any apparent side effects. The author discovered for the first time that oral administration of 5-Fu could improve the liver function as manifested by a marked decrease of serum GPT level in advanced gastric cancer.

Seventy one patients with renal tumors treated at our clinic during the 11 years from 1970 to 1980 were clinically examined. The results are summarized as follows. The frequency of patients with renal tumors was 0.22% of the outpatients and 1.72% of the inpatients. Of the 71 renal tumors, 41 were renal adenocarcinoma, and 26 were renal pelvic tumors of which 23 were transitional cell tumors, 2 were squamous cell tumors, and 1 was adenocarcinoma. The other tumors were 1 adenoma, 1 hemangioma, 1 hematoma, and 1 foreign body granuloma. The right and left kidneys were affected at equal frequencies. Male patients were more commonly affected, the sex ratio being 39 to 32. The youngest case was a 29-year-old female, and the eldest was a 84-year-old male. As the initial symptoms and chief complaints, gross hematuria was most frequent (52 cases, 73.2%), followed abdominal tumor mass (32 cases, 45.1%), and fever (26 cases, 36.6%). Only 2 cases showed the classic triad, while 1 case had none of them. The period between onset of symptoms and admission, was within 1 year for all patients except for 2 cases. Metastasis was found in 52 cases. The lung was the most frequent site of metastasis (12 cases, 23.1%), followed by lymphnodes, bones, and liver. The clinical examinations performed and diagnostic techniques used were, renal function (BUN, Serum Cr), Hb, WBC, liver function (T. Bil, GOT, GPT), serum protein fraction, serum LDH, serum Ca, ESR, tumor marker (AFP, CEA), urine cytological examination, blood pressure, IVP (or RP), angiography. As the therapeutic method, nephrectomy was performed in 25 cases (35.2%), combined nephrectomy and irradiation therapy in 12 cases (16.9%), combined nephrectomy and chemotherapy in 11 cases (15.5%), combined nephrectomy and other therapy in 15 cases (21.1%), and conservative therapy in 8 cases (11.3%). For the entire traced series of renal tumors, the 1-, 3-and 5-year survival rates were 72.3, 49.8, and 49.8% respectively. For renal parenchymal tumors (renal adenocarcinoma), the 1-, 3-and 5-year survival rates were 77.8, 53.0, and 53.0%. The most important factor of prognosis was the stage of tumor. Patients with elevated erythrocyte sedimentation rate, and dysproteinemia also had distinctly unfavorable prognosis. In this study of therapy, the highest survival rate was seen for the patients treated by combined nephrectomy and irradiation therapy of both renal parenchymal and pelvic tumors.

A 54-yr-old man was admitted to Hokkaido University Hospital, complaining of fever, multiple arthralgia, edematous erythema and face and muscular weakness of extremities during the last 2 months. He was diagnosed as dermatomyositis by acceleration of ESR, elevation of GOT, GPT, CPK, aldolase, moderate increases of collagen fibers in biopsy specimen of skin and his clinical signs. Although stools were positive for occult blood, the routine radiographic examination failed to detect the bleeding site in the upper GI. tract. However, in the double contrast picture of the stomach, a very fine abnormal linear shadow was observed at the upper corpus of the lesser curvature. This linear shadow was a margin of the tumor, retrospectively. About 4 months later, abnormal pain occurred and a mass was palpable in the left lumbar region, suggesting a pancreatic tumor. He was operated on excising the tumor, but was performed only exploratory laparotomy because of the presence of intra-abdominal metastases. Death occurred 40 days after the operation and necropsy was done. The gross anatomical findings of the abdomen showed a stomach tumor as large as an infant's head and its metastases to pancreas, lymph nodes, and greater and lesser omentum. Esophageal mucosa including esophagocardiac junction was intact. Histological examination of the intragastric tumor revealed a typical squamous cell carcinoma with keratinization. According to the absence of the components of adenocarcinoma and squamous metaplastic gastric mucosa of non-cancerous areas in the stomach, it seemed likely to be a heterotopic squamous cell carcinoma. It was unknown about the precedence between the stomach cancer and dermatomyositis. There have been 11 cases of primary pure squamous cell carcinoma in the world literature since 1968, but this is the first case report of coexistence of these two diseases.
