The effects of chemotherapy for lung metastasis in 284 cancer patients using various anti-tumor drugs, including classic ones and modern active agents for the past 18 years, were presented. Lung metastasis for lung cancer was excluded. The response was achieved in cervical carcinoma of the uterus (17/62, 27%), endometrial carcinoma of the uterus (1/7, 14%), colorectal cancer (6/39, 15%), breast cancer (5/28, 18%) and stomach cancer (4/28, 14%). A high response was achieved in myosarcoma (5/12, 42%), testicular cancer (5/11, 45%) and also in ovarian cancer (3/10, 30%). Though there were few cases, a high response was achieved in malignant melanoma (2/3), choriocarcinoma (2/4) and esophageal cancer (1/3). In total patients the response rate was 20%. In these cases a complete response was achieved in 4 cervical cancers; one testicular cancer, ovarian cancer, esophageal cancer and renal cancer, respectively. However, the effect was temporary and no longterm survivor was observed except for one case of renal cancer treated continuously with interferon (3 X 10(6) units daily) and showing complete remission after 7 months of therapy. The effect of chemotherapy for lung metastasis was compared between nodular metastasis (NM) and lymphagiosis carcinomatosa (LC). In cervical carcinoma of the uterus, the response rate in NM (39%) was higher than in LC (11%). However, no difference was observed in breast cancer (NM 15%, LC 13%) nor in stomach cancer (NM 13%, LC 18%).

Antitumor activity of cis-dichlorodiammineplatinum(II) (cisplatin) on various mouse transplantable tumors was investigated. Cisplatin was active against a wide variety of the following tumor systems: L1210 leukemia, P388 leukemia, B16 melanoma, colon tumor 38, Ehrlich ascites and solid carcinoma, WHT squamous cell carcinoma, and human stomach cancer G/S heterotransplanted in nude mice. From the comparison of growth inhibitory effect by cisplatin with various other antitumor agents in cultured Ehrlich ascites carcinoma cells, cisplatin was found to be mainly a concentration depending drug, but also time depending, so that it was identified as a type Ib class drug proposed by Shimoyama. Effect of cisplatin on the cell cycle progression of Ehrlich ascites carcinoma cells in mice was studied by flow cytometry of DNA. At an early stage after administration of cisplatin, cell cycle progression was delayed in S phase and blocked in G2 phase. With the elapse of time block in G1 phase or G1-S boundary was observed and the cell population, partially synchronized in G1 phase or G1-S boundary, progressed slowly through S phase to be blocked in G2 phase finally.

Human fibroblast interferon(HFIF) was used in 26 patients with various malignant diseases, most of whom had previous chemotherapy. The dosages used were 3 X 10(6) IU or 6 X 10(6) IU of HFIF i. v. daily. Out of 24 evaluable patients, there were 2 partial remissions (CLL 1 and multiple myeloma 1), and 7 stable diseases (multiple myeloma 2, stomach cancer 2, non-Hodgkin's lymphoma 1, CLL 1 and malignant melanoma 1). The majority of the patients experienced fever exceeding 38 degrees C and chills, which became uncommon within several days of treatment. Other side effects included myelosuppression, general malaise, anorexia, hepatic dysfunction and renal dysfunction, which were mild and tolerable.

We have utilized a recently developed human tumor cloning system to screen for antitumor effects in vitro of a new anthracenedione derivative, Mitoxantrone. The object was to determine if the system is useful for pinpointing the types of tumors in patients which should be studied in early Phase II clinical trials. Tumors from 267 patients were placed in culture (20 different histological tumor types). One hundred seventy tumors both grew and formed enough colonies for drug sensitivity assays. Excellent in vitro antitumor activity was noted for Mitoxantrone against human adenocarcinoma of the lung, small cell lung cancer, melanoma, and biliary tree cancer. Good antitumor activity was noted against breast cancer, ovarian cancer, non-Hodgkin's lymphoma, head and neck cancer, squamous cell lung cancer, soft tissue sarcoma, gastric cancer, and hepatomas. The drug showed no in vitro activity against colon cancer. These data indicate that Mitoxantrone has a wide spectrum of in vitro antitumor activity. A comparison of these in vitro results with the results of Phase II clinical trials with the drug should allow an evaluation of the utility of the human tumor cloning system for predicting clinical antitumor activity of a new compound.

Studies of cancer mortality in migrants, in Australia and elsewhere, gave rise to aetiological hypotheses about various environmental factors. The advent of population-based cancer registration in Australia allows comparison of cancer incidence by country of birth, thereby eliminating any biases that might occur in mortality comparisons due to differences in cancer survival rates between population subgroups. Examination of cancer incidence in British, Irish and southern-European migrants in South Australia during 1977-1978, relative to the non-migrant population, shows a high risk of stomach cancer in all these migrants and a low risk of colon cancer in southern-European migrants. Variations in malignant melanoma and in cancers of the oesophagus, lung, pancreas, breast and endometrium are also discussed, in relation to eating, drinking and smoking habits, and host characteristics. The potential uses of cancer registration data for population monitoring, and for research, are noted.

We have utilized a recently developed human tumor cloning system to screen for antitumor effects in vitro of a new anthracene derivative, CL216,942. The object was to determine whether the system is useful for pinpointing the types of tumors in patients which should be studied in early phase II clinical trials. Tumors from 684 patients were placed in culture (27 different histologic tumor types). Two hundred seventy-three tumors both grew and formed enough colonies for drug sensitivity assays. In vitro antitumor activity was noted for CL216,942 against human breast cancer, ovarian cancer, renal cancer, squamous cell, small cell and large cell lung cancer, lymphoma, acute myelogenous leukemia, melanoma, adenocarcinoma of unknown origin, adrenal cancer, gastric cancer, pancreatic cancer, and head and neck cancer. The drug definitely showed no in vitro activity against colon cancer. These data indicate that CL216,942 has a wide spectrum of in vitro antitumor activity. A comparison of these in vitro results with the results of phase II clinical trials with the drug should allow an evaluation of the utility of the human cloning system for predicting clinical activity of a new compound.

Sequential evaluation of lymphocyte blastogenic response (LBR) to PHA was performed in 10 melanoma patients and in 10 gastric cancer patients undergoing radical operations. Preoperative determinations showed a significant depression of LBR in both patient groups as compared to healthy controls. In patients operated for melanoma the average duration of anesthesia was 101 minutes and in patients who underwent gastric resection it was 192 minutes. In both patient groups a further significant depression of LBR was observed in the early postoperative period; however the LBR returned to preoperative levels more promptly in patients who underwent melanoma excision than in those who underwent gastric resection.

Construction, one of the larger industries in the United States, employs 7.6 million workers, many in skilled trades occupations. Previously published data about potential worksite exposures and mortality of construction site workers are limited. We analyzed occupation and industry codes on death certificates from 19 U.S. states to evaluate mortality risks among men and women usually employed in construction occupations. Proportionate mortality ratios (PMRs) for cancer and several other chronic diseases were significantly elevated among 61,682 white male construction workers who died between 1984 and 1986. Men younger than age 65, who were probably still employed immediately prior to death, had significantly elevated PMRs for cancer, asbestos-related diseases, mental disorders, alcohol-related disease, digestive diseases, falls, poisonings, traumatic fatalities that are usually work-related, and homicides. Elevated PMRs for many of the same causes were observed to a lesser degree for black men and white women whose usual industry was construction. In addition, women experienced excess cancer of the connective tissue and suicide mortality. Various skilled construction trades had elevated PMRs for specific sites, such as bone cancer and melanoma in brickmasons, stomach cancer in roofers and brickmasons, kidney and bone cancer in concrete/terrazzo finishers, nasal cancer in plumbers, pulmonary tuberculosis in laborers, scrotal cancer and aplastic anemia in electricians, acute myeloid leukemia in boilermakers, rectal cancer and multiple sclerosis in electrical power installers, and lung cancer in structural metal workers. Using a standard population of blue collar workers did not result in fewer elevated PMRs for construction workers. Despite lifestyle differences and other limitations of the study, the large numbers of excess deaths observed in this study indicate the need for preventive action for construction workers.

Docetaxel has been evaluated in six tumour types in a total of 189 patients entered into phase II studies. Treatment consisted of a 1 h intravenous infusion of docetaxel 100 mg/m2 repeated every 3 weeks. No premedication was administered for possible hypersensitivity reactions. Docetaxel was found to be effective as first-line chemotherapy for head and neck cancer (response rate 44%) gastric cancer (23%) and melanoma (14%) and as second-line chemotherapy for soft tissue sarcomas (21%; 95% confidence interval: 7.5%-43.7%). The results in colorectal and renal cancer were disappointing, with response rates of less than 10%. The most frequent adverse effects were alopecia (81%), grade III-IV leukocytopenia of short duration (66%) and skin reactions (52%). Hypersensitivity reactions were mild and occurred in 26% of patients. Docetaxel is an important new drug in the treatment of solid tumours.

Risk of cancer mortality from 1973 to 1985 in persons born in the Indian subcontinent who migrated to England and Wales was analysed by ethnicity, and compared with cancer mortality in the England and Wales native population, using data from England and Wales death certificates. There were substantial highly significant raised risks in Indian ethnic migrants for cancers of the mouth and pharynx, gall bladder, and liver in each sex, larynx and thyroid in males, and oesophagus in females. There were also substantial raised risks in these migrants of each sex for non-Hodgkin's lymphoma and myeloma. For the mouth and pharynx, and liver in each sex, and gall bladder in females, there were also raised risks of lesser magnitude in British ethnic migrants. For colon and rectal cancer and cutaneous melanoma in each sex, ovarian cancer in women and bladder cancer in men, there were appreciable significantly reduced risks in the Indian ethnic migrants not shared by those of British ethnicity. Appreciable raised risks in British ethnic migrants not shared by those of Indian ethnicity occurred for nasopharyngeal cancer in males, soft tissue malignancy in both sexes and non-melanoma skin cancer in males. In migrants of both ethnicities there were appreciable significantly raised risks in each sex for leukaemia and decreased risks in each sex for gastric cancer, for lung cancer except in females of British ethnicity and in males for testicular cancer. The results suggest the need for public health measures to combat the high risks of oral and pharyngeal cancers and liver cancer in the Indian ethnic immigrant population of England and Wales, by prevention of betel quid chewing and hepatitis transmission respectively. The data also imply that early exposures or early acquired behaviours in India, or exposures during migration, may increase the risk of leukaemia and reduce the risks of gastric and testicular cancers in the migrants irrespective of their ethnicity. Aetiological studies would be worthwhile to investigate the reasons for the sizeable decreased risk of colon and rectal cancer and increased risk of gall bladder cancer in each sex and the increased risk of thyroid and laryngeal cancer in males and oesophageal cancer in females of Indian ethnicity but not of British ethnicity who have migrated from the Indian subcontinent.
