Most humans in the United States have been infected with BK virus (BKV), a human papovavirus. Because BKV has oncogenic properties, we have investigated whether it may be a cause of human cancer. Basic principles of tumor virology imply that BKV-induced tumors should contain BKV DNA sequences. Therefore, we assayed (by molecular hybridization) DNA from human tumors and malignant cell lines for BKV DNA, using BKV [(32)P]DNA as probe. The BKV [(32)P]DNA was labeled in vitro (nick translation) to specific activities of 1 to 2 x 10(8) cpm/mug. The BKV DNA used to prepare our probes had the properties expected of authentic BKV genomes, including density of superhelical DNA, sedimentation velocity in alkaline and neutral sucrose gradients, production of one fragment by endonuclease EcoRI cleavage and four fragments by endonuclease Hin II + III cleavage and reassociation properties. From these studies we conclude that our BKV probes hybridized well, and represented bona fide BKV DNA. Using three different BKV [(32)P]DNA probes, i.e., from three distinct plaque isolates, we have analyzed DNA from BKV-transformed cells, normal human tissues, and a large number of human tumors. All human DNAs (cell lines, normal tissues, tumors) hybridized 5% with BKV DNA. Hybridization analysis of BKV-transformed hamster cell DNA indicated 5-6 copies of at least 88% of the BKV genome per cell. No BKV DNA sequences were detected (above the normal 5% hybridization to all human DNAs) in the following normal human tissues: 10 kidney (BKV is usually isolated from urine), 3 spleen, 13 lung, 23 colon, 2 rectum, 1 ileum, and 1 skin. No BKV-specific DNA was found in 166 tumors, including 5 carcinomas (Ca) of stomach, 3 Ca small intestine, 26 Ca colon, 9 Ca rectum, 31 Ca lung, 9 adenocarcinomas and 5 oat cell carcinomas of lung, 17 melanomas, 5 Ca prostate, 4 Ca bladder, 6 Wilms tumors, 4 hypernephromas, 15 Ca kidney, 7 brain tumors, 5 Hodgkin lymphomas, 10 lymphomas (immunosuppressed patients have a high incidence of lymphomas), 2 reticulum cell sarcomas (spleen), and 3 skin tumors. We have also analyzed 7 human malignant cell lines (melanoma, lung, rhabdomyosarcoma, and glioblastomas), including several clones of a lung melanoma line; no BKV DNA sequences were detected. Because our probes could detect one copy of BKV DNA if only 10% of the cells were tumor cells, our results are very strong evidence that the tumors we analyzed did not have a BKV etiology. The tumors we tested represent about 50% of all cancers in the United States; there is no evidence that BKV is involved in the etiology of these types of tumors.

The Authors describe the various anomalies of the metabolism of tryptophan that are observed in various diseases. The oxidative pathway is most important of the metabolic pathway of the amino acid; the degredation of tryptophan is particularly influenced by steroid hormones and vitamins' want. The metabolic anomalies are demonstrable both in malignant tumors (mostly in bladder cancer and Hodgkin's disease), both during psychiatric diseases (such as depression and schizophrenia) and in the diseases of connective tissue in addition to congenital errors of the degradation of tryptophan (such as Hartnup's disease, tryptophanuria and 3-hydroxychinureninuria). The metabolic pictures are manifest after amino acid's in the diseases of connective tissue but are independent for clinical seriousness and, in any case, less significant than those observed in other pathological pictures, mostly in Hodgkin's disease. The existence of anomalies of tryptophan's metabolism is certainly shown in many diseases, however the true physiopathogenetic meaning of these metabolic alterations is not yet specified. Particularly it is not definite if these alterations are the cause of diseases, which they appear in, or if they are secondary alterations.

Urinary bladder cancers following prolonged cyclophosphamide therapy are being increasingly reported. We report a case of transitional cell carcinoma of the urinary bladder occurring 12 years after pulse intravenous therapy with cyclophosphamide for Hodgkin's disease. The mechanism of bladder carcinogenesis and the possible role of the uroprotector MESNA in preventing cyclophosphamide induced bladder cancer are discussed.

The scheduling of chemotherapeutic agents may be important in optimising their antitumour actions. This has been explored in non-Hodgkin lymphoma, osteogenic sarcoma and bladder cancer with improved results using intensive, weekly dosing schemas. We began a phase II study of cisplatin, 5-fluorouracil and vinblastine in non-small cell lung cancer (NSCLC) on a weekly schedule. 38 patients with advanced or metastatic NSCLC were entered; 32 are evaluable for response. 11 patients were treated with 5-fluorouracil 1.5 g/m2 and vinblastine 4 mg/m2 by 24-h continuous infusion, and cisplatin 30 mg/m2 over 30 min, 6-8 h after the start of the infusion. Because of prohibitive myelotoxicity, the next 27 patients received 5-fluorouracil 1.2 g/m2 and vinblastine 3 mg/m2. None had had prior chemotherapy while 6 had had previous radiation therapy. Myelosuppression was the predominant toxic effect. Other side-effects included neuropathy, diarrhoea, mucositis, nausea and vomiting. 32 patients are evaluable for response: there have been 14 partial remissions (44%). Responses have occurred chiefly in lung and lymph nodes. The median survival on this study is 7 months, and responders did not live longer than non-responders. While this regimen is well tolerated by the majority of patients and has a response rate comparable to other active regimens identified in single institution studies, survival does not appear to be enhanced. We conclude that the schedule manipulation described here does not enhance the therapeutic index of these drugs in NSCLC.

We have carried out cytogenetic studies, using the G-banding technique, in peripheral blood lymphocytes of 10 patients affected by breast carcinoma. The frequency of aberrant metaphases (7.36%) is significantly different from that of our laboratory controls (3.76% of aberrant metaphases) but not from that detected in patients suffering from bladder cancer (10.64%) and Hodgkin's disease (11.03%), two conditions that have previously been described as chromosomally unstable. Our results suggest that breast carcinoma patients show a degree of chromosomal instability that could be related to a predisposition to neoplastic disease.

The risk of second malignancies following non-Hodgkin's lymphoma (NHL) was estimated in 29,153 patients diagnosed with NHL between 1973 and 1987 in one of nine areas participating in the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. Compared with the general population, NHL patients were at a significantly increased risk of developing second cancers (observed/expected [O/E] = 1.18; O = 1231). The O/E ratio increased significantly with time to reach 1.77 in 10-year survivors. Significant excesses were noted for acute nonlymphocytic leukemia (O/E = 2.88), cancers of the bladder (O/E = 1.30), kidney (O/E = 1.47), and lung (O/E = 1.57), malignant melanoma (O/E = 2.44), and Hodgkin's disease (O/E = 4.16). Chemotherapy appeared related to subsequent acute nonlymphocytic leukemia (ANLL) and bladder cancer. Radiation therapy was associated with ANLL and possibly cancers of the lung, bladder, and bone. Malignant melanoma was not clearly related to initial NHL treatment.

In a study of 6,389 male cancer patients diagnosed and treated at the Cancer Control Agency of British Columbia from 1950-1975, several associations were detected between occupation and specific cancers. Elevated risks for lung cancer were seen in miners, metal processors and machinists, while a reduced risk was seen in farmers. Lip cancer excesses were detected in individuals involved in several outdoor occupations, and melanoma excesses were seen for three groups of predominantly indoor workers. These results confirm previous findings in the literature, whereas the following associations have not been previously reported. Fishermen were found to have an excess of Hodgkin's Disease (RR = 3.0, 95% C.I. = 1.4,6.5), engineers are at an elevated risk of cancer of the pancreas (RR = 4.2, C.I. = 1.8,9.9), and forestry workers have an elevated risk of bladder cancer (RR = 1.7, C.I. = 1.1,2.6). Further studies will be needed to replicate the new associations detected here.

In 1979-1987, 570 patients with non-Hodgkin's lymphomas (226 female and 344 male patients) were treated at the Department of Hematology of the Pomeranian Medical Academy and hematological outpatient clinic. The second malignant tumors were diagnosed in 25 (4.4%) patients. Two patients suffered from three malignant tumors. The most frequent combination of 2 tumors were: non-Hodgkin lymphoma and cancer of the lungs in 8 patients, non-Hodgkin lymphoma and cancer of the skin in 6 patients, non-Hodgkin lymphoma and cancer of the larynx in 4 patients, non-Hodgkin lymphoma combined with cancer of the stomach in 2 patients, and non-Hodgkin lymphoma together with cancer of the bladder in 2 patients. Moreover, non-Hodgkin lymphoma coexisted with cancer of the colon, cervix and prostate (one case of each). The authors stress the possibility of other malignant tumors in patients with non-Hodgkin lymphomas and occurrence of the subsequent neoplasms without preceding chemo- or radiotherapy.

Alkylating agents have caused acute nonlymphocytic leukemia (ANLL), probably bladder cancer, and possibly other solid tumors. Phenacetin also has enhanced risk of bladder cancer, and probably also carcinoma of the renal pelvis. Topical nitrogen mustard, potassium arsenite, tar ointments, and methoxsalene have been related to development of nonmelanotic skin cancers. Immunosuppression by azathioprine, usually with prednisone, has enhanced risks of non-Hodgkin's lymphomas, hepatobiliary cancers, and various mesenchymal tumors. Liver cancers have been reported in users of androgenic anabolic steroids, and both hepatic cell adenomas and carcinomas have been associated with use of combined oral contraceptives. These contraceptives reduce risks of endometrial and ovarian carcinomas. Estrogens increase risk of endometrial cancer. Exposure to diethylstilbestrol in utero can result in clear cell carcinomas of the vagina and cervix, and possibly testicular carcinomas.

The relationship between an index of dietary vitamin A and cancer risk at 25 sites was assessed in retrospective case-control studies. Common control groups for males and females were used in all analyses. Relative risk estimates were derived from multiple logistic regression analyses that controlled for age, alcohol consumption, and smoking exposure. We found that among males, dietary vitamin A is associated with lower risk for cancers of the tongue, floor and other mouth, pharynx, larynx, esophagus, and lung but higher risk for Hodgkin's disease and leukemia. Among females, we found that dietary vitamin A had less effect on risk generally but was associated with lower risk for bladder cancer. These findings are consistent with previous research that showed dietary vitamin A to be associated with decreased risk of squamous epithelial cancers. The association of dietary vitamin A and increased risk of Hodgkin's disease and leukemia among males in addition to the disparity in effect of dietary vitamin A on risk between males and females are areas worthy of further research.
