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%).

The present level of understanding of the known risks of oral contraceptive (OC) use are summarized. The findings of many investigations in the late 1960s and early 1970s may no longer be totally appropriate because OCs available then had higher dosages than today. Also, early studies enrolled predominantly women in their 20s, who are now almost all more than 35 years old. Thus, the risks observed in these studies may not be applicable to younger women using OCs today. Another consideration has been underscored by the results of the Walnut Creek Study. Behavioral characteristics such as smoking, drinking, and sexual activity are factors which can strongly confound risks of OC use and must be considered when assessing current and future investigations. Many studies have clearly shown that the most serious life threatening danger associated with OC use is that of cardiovascular complications arising from the interaction of OC use and smoking. The increased risks attributable to smoking while using OCs account for a substantial number of the deaths recorded. The Walnut Creek Study showed a somewhat different outcome. Its data suggest no significant risk of myocardial infarction (MI), ischemic heart disease, cerebral thrombosis, or ischemic cerebrovascular disease associated with OC use, but there were nonsignificant increases noted in some cardiovascular diseases which appeared to be explained by a synergism between current use and heavy smoking. Age also has a strong influence on risk for cardiovascular disease. The results of earlier studies seem to indicate that OC use is associated with a risk of subarachnoid hemorrhage. The Walnut Creek Study also noted an increased risk of subarachnoid hemorrhage associated with OC use and found that risk increased with use. Several studies have shown that the incidence of venous thrombosis seems dependent on the dosage of the OC used. An overwhelming majority of studies on the carcinogenicity of OCs have found no increased incidence of cancer of the ovaries, uterus, or breast among users. In regard to both ovaries and endometrium, there is some evidence that OCs may be protective. Several studies have concluded that OC users have a slightly increased risk of developing malignant melanoma. The results of the Oxford/Family Planning Study show that although previous use of OC by nulliparous women may delay future childbearing by several months, it does not impair longterm potential for pregnancy. No increase in risk of clinically apparent diabetes mellitus has been reported in users. In addition to their possible protection against ovarian and endometrial cancer, OCs may reduce the risk of at least 5 other diseases: benign breast disease; deficiency anemia; arthritis, pelvic inflammatory disease; and ovarian cysts.

This paper reviews both minor and major adverse reactions caused by estrogenic substances (natural and synthetic, steroidal and nonsteroidal) of which diethylstilbestrol is the prototype of nonsteroidal synthetic estrogen. Minor side effects include nausea, breast tenderness, and excessive cervical secretions (most common), headache, and water and salt retention (less common and often eradicated by lowering estrogen dosage). Vertigo, yeast infections, depression, and photosensitivity are other minor effects. Major side effects are discussed in some detail. Major effects include those on the endocrine system (e.g., feminization in boys and men and precocious puberty in girls); breast tumors; endometrial carcinoma; ovarian tumors; hypertension; thromboembolism; blood clotting excesses; various metabolic effects (including lipid metabolism and carbohydrate metabolism alterations); liver changes (bile alterations and neoplasms); porphyria; melanoma; and effects on a fetus in situ during maternal estrogen administration. In general, lowering doses of estrogen should help eradicate or alleviate most of these effects.

The clinical characteristics of patients with second primary tumors in the ovary and endometrium were compared to those with single primary tumors treated at our Center during the same period of time. Despite the fact that the patients were under medical surveillance for the first primary tumor, most second tumors were diagnosed following patient symptoms and complaints, and not at a routine follow-up appointment. Patients with a second primary endometrial cancer had a more advanced stage of disease at diagnosis as compared to those with single endometrial cancer. This was not found to be true for patients with second ovarian cancer. Patients with primary breast cancer and colon cancer, lymphoma or melanoma were found to be at higher risk for developing a second primary tumor in the endometrium or ovary as compared to those with a primary tumor at other sites. Although there are no proven means for the early detection of these gynecologic malignancies, it seems prudent to draw the attention of medical practitioners to the need for a better gynecologic evaluation for women with cancer at other sites during their follow-up visits. Studies on the efficacy of currently available diagnostic techniques should be carried out to evaluate their yield in this high risk group.

Some animal data have raised the possibility that benzodiazepines influence the risk of selected cancers. With data collected in 1977-1991 in a US hospital-based study, the authors assessed the relation of benzodiazepine use to the risk of 11 cancers: breast (6,056 patients), large bowel (2,203), malignant melanoma (1,457), lung (1,365), endometrium (812), ovary (767), non-Hodgkin's lymphoma (382), testis (314), Hodgkin's disease (299), thyroid (111), and liver (37). Cases were compared with cancer controls (3,777 patients with other cancers) and noncancer controls (1,919 patients admitted for acute nonmalignant disorders). Relative risks were estimated for benzodiazepine use at least 4 days a week for at least 1 month, initiated at least 2 years before admission (sustained use) by multiple logistic regression with control for confounding factors. Results derived with noncancer controls were similar to those derived with cancer controls. For sustained benzodiazepine use relative to no use, relative risk estimates for all 11 cancers were compatible with 1.0 at the 0.05 level of significance. Relative risk estimates for durations of at least 5 years were also compatible with 1.0, with the exceptions of an increased estimate, of borderline statistical significance, for endometrial cancer, and a decreased estimate for ovarian cancer. Relative risk estimates both for sustained use that continued into the 2-year period before admission and for sustained use that ended up to > or = 10 years previously were compatible with 1.0, suggesting a lack of tumor promotion and no increase in the risk after a latent interval. Results were also null for diazepam, chlordiazepoxide, and other benzodiazepines considered separately. The results suggest absence of association between benzodiazepine use and the cancers considered, with the evidence stronger for the cancers with larger numbers of subjects. The similarity of results derived with cancer and noncancer controls suggests that benzodiazepines do not influence the risk of cancer as a whole.

The evidence of the effects of combined oral contraceptives (COCs) on mortality and morbidity is reviewed. All the 11 case-control studies published since 1980 reported and approximate halving of endometrial cancer risk among COC users. The CASH study showed that the protective effect was apparent after 12 months' use, and users had 40% of the risk of non-users after 2 years' use. A study showed that 5 patterns of self-perceived prolonged, heavy, frequent, irregular, or painful bleeding during menstruation were reported less frequently in COC users than in users of other methods. Benign breast disease is rarer, and functional ovarian cysts are less frequent in COC users. Lower-dose preparations may carry a lower risk of myocardial infarction. Smoking possibly potentiates the risk associated with oral contraceptive (OC) use, and it is a major risk factor for myocardial infarction. The Oxford/FPA study found a 2-3-fold increase in incidence of non-haemorrhagic stroke among current OC users. The epidemiologic data on the current risk of venous thromboembolism in relation to OC use are equivocal. New lower dose COCs have a smaller adverse effect on the lipid profile: they cause a smaller increase in low density lipoprotein cholesterol (LDL) and a variable but smaller decrease in high density lipoprotein cholesterol (HDL). The large CASH study, based on 2088 cases, found a significantly elevated relative risk (2.7) of breast cancer, but only in women who had used the OC for at least 11 years. Of 6 case-control studies of hepatocellular carcinoma and OC use published since 1983, all but one showed a large elevated relative risk of around 4-fold. Delayed return of fertility has been observed in nulliparous women 30 who had 2 years; continuous exposure to COCs, although this may not be associated with low-dose, modern OCs. Malignant melanoma, pituitary adenoma, gallbladder disease, and chronic inflammatory bowel disease have been possibly associated with adverse side effects, but results are so far inconclusive.

To quantify the risk of second primary cancers among patients with cutaneous malignant melanoma, we studied 20,354 patients in the Swedish Cancer Register during 1958-88. A second primary cancer was reported in 1605 patients, compared with an expected number of 1109.5 [standardised incidence ratio (SIR) = 1.45, 95% confidence interval (CI) = 1.38-1.52]. The highest risk was found among patients younger than 60 years. The greatest risk was seen during the first year after diagnosis (SIR = 1.91, CI = 1.69-2.14), but even after long-term follow-up--15 years or more--the risk was still significantly elevated (SIR = 1.56, CI = 1.35-1.79). The strongest association was found for a second primary malignant melanoma (men, SIR = 10.0, CI = 8.26-12.00; women, SIR = 8.66, CI = 7.22-10.30) and non-melanoma skin cancer (men, SIR = 3.58, CI = 2.85-4.44; women, SIR = 2.41, CI = 1.71-3.29). The risk of second cancers associated with tissues of neuroectodermal origin was increased, especially tumours of the nervous system (men, SIR = 1.73, CI = 1.10-2.60; women, SIR = 2.03, CI = 1.45-2.78). The SIR of second cancers involving the immune system was also increased. An excess risk of endometrial cancer was seen (SIR = 1.41, CI = 1.03-1.88), but no significant associations existed for cancers of the breast, ovary, testis or other endocrine glands. Among tumours of the digestive tract, only colon cancer in men had a significantly increased SIR (1.33, CI = 1.00-1.74).

Endobronchial metastasis (EM) from nonpulmonary tumors is uncommon. A 9-year retrospective study at the University Hospital Vall d'Hebron (Barcelona, Spain) identified 32 patients with EM. All but four cases were diagnosed by fiberoptic bronchoscopy with bronchial biopsy. Primary tumors included the following types: breast cancer (20), colorectal cancer (3), melanoma (2), gastric cancer (1), neuroblastoma of the olfactory nerve (1), abdominal leiomyosarcoma (1), hypernephroma (1), endometrial carcinoma (1), papillary thyroid cancer (1), and hepatocarcinoma (1). Median age at diagnosis of EM was 58.7 years and median interval from the diagnosis of the primary tumor to the diagnosis of EM was 50.4 months. Seventeen patients (53%) had evidence of other metastatic sites at endobronchial relapse. The more common clinical manifestations included cough (37.5%), haemoptysis (28%), dyspnea (18.7%), and recurrent pulmonary infections (6.2%). Eight patients (25%) had no symptoms. There appears to be a predilection for metastatic involvement of the right and left upper lobe bronchus. Treatment was instituted in 20 patients, and their median survival was 11 months, in comparison with the 3 months found in 12 patients who received only palliative therapy because of advanced disseminated disease. Breast cancer is the most common tumor causing EM. The prognosis of patients with EM depends on the type of the primary tumor and the presence of other metastatic sites. Treatment must be individualized.

We analyzed cancer incidence and mortality in a cohort of 22,597 Swedish women who were prescribed replacement hormones. After 13 years of follow-up in national registries, 2,330 incident cancer cases and 848 cancer deaths were observed. Overall, our results were reassuring since incidence rate ratios (SIRs) for 16 cancer sites and mortality ratios (SMRs) for all 10 examined sites were at, or lower than, unity. However, we found that exposure to an estrogen-progestin combined brand was associated with an increasing relative risk of breast cancer with follow-up time, the SIR reaching 1.4 (95% CI 1.1-1.8) after 10 years of follow-up. The relative risk of endometrial cancer was substantially increased, with the highest SIR of 5.0 (95% CI 1.6-5.9) in women prescribed estrogens alone, whereas those given an estrogen-progestin combination showed no elevation in risk. The risk estimates for liver and biliary tract cancers and for colon cancer were reduced by about 40%, notably in women prescribed the estradiol-progestin compound. Further detailed analyses revealed no evidence of adverse or protective effects on the risk of ovarian, uterine cervical, vulvar/vaginal, rectal, pancreatic, renal, lung, thyroid and other endocrine cancers, brain tumors, malignant melanoma or other skin cancers. Hormone replacement therapy was not associated with an increase in mortality for any cancer site, at this time of follow-up. For breast and endometrial cancers, SMRs were below baseline but tended to increase with follow-up time. We conclude that hormone replacement increases the endometrial-cancer risk after unopposed estrogens and the breast-cancer risk-notably after estrogen-progestin combined therapy-and tentatively suggest that it exerts a protective effect against colon and liver cancer risks.

The expression of nm23 has been shown to correlate in some solid tumours with their metastatic potential and to be associated with a favourable prognosis in human breast cancer and melanoma. In breast and ovarian cancer nm23 expression is also correlated with lymph node involvement. We analysed the expression of nm23-H1 and -H2 in normal endometrium and in endometrial and cervical cancer by both Northern and Western blotting. Cellular localisation of Nm23-H1 was visualised by immunohistochemistry mostly in the cytoplasm. Both isoforms of Nm23 were present in all the samples analysed, and a clear direct correlation between Nm23-H1 and -H2 levels was evident. Median nm23-H2 levels were higher than than -H1 levels in both tissues. Cervical cancer patients with lymph node involvement were shown to have significantly lower protein levels of Nm23 (P < 0.007 for H1 and P < 0.009 for H2), and a similar trend was also evident in endometrial cancer. Furthermore, the degree of myometrial invasion in endometrial cancer patients was also inversely correlated with Nm23-H1 levels of expression (P < 0.003). Nm23 level may therefore be taken into consideration as a new marker in the prognostic characterisation and in the treatment planning of uterine tumour patients.
