- The clinicopathological and immunocytochemical features of nine cases of salivary duct carcinoma are described. This relatively rare tumour, which only recently has been widely recognized as a separate entity, is highly malignant and caused the death in eight of the patients. The tumour cells are arranged in cribriform and solid growth patterns, where the solid tumour nests frequently have comedo necrosis, and a fibrous, often sclerotic, stroma is present. The infiltrating desmoplasmic component and the diffuse invasive growth into adjacent adipose parotid tissue have similarities to ductal breast carcinoma. Immunocytochemical investigation of salivary duct carcinoma showed constant overexpression of c-erbB-2 as detected by membrane accentuation, and high proliferative activity as detected by nuclear positivity for MIB 1 (Ki-67). Changes in the expression of p53 and retinoblastoma gene product do not constitute a constant event in salivary duct carcinoma. A few of the tumours showed scattered cells with distinct nuclear positivity for both progesterone and oestrogen receptors. We emphasize that this highly malignant salivary gland tumour has a characteristic morphology, may not be as rare as previously considered, and that prompt and aggressive therapy is needed.

- This report describes maternal and perinatal risk factors for Wilms' tumor analyzed in a case-control study nested in a nationwide cohort in Sweden. The Swedish National Cancer Registry ascertained 110 cases from among successive birth cohorts from 1973 through 1984, identified by the Swedish Medical Birth Registry, the latter based on medical records. From the Birth Registry, we matched 5 controls without cancer to each case by sex and date of birth. Wilms'-tumor children were more likely to have mothers who had been exposed to penthrane (methoxyflurane) anesthesia during delivery than mothers of controls (odds ratio (OR) = 2.4; 95% confidence interval (CI) 1.1 to 5.1); this excess risk was higher in females than males and increased with age at diagnosis. Wilms'-tumor cases were also more likely to have had physiologic jaundice (OR = 2.3; 95% CI 1.1 to 5.0). Higher parity of the mother decreased the risk of Wilms' tumor among females (OR = 0.7; 95% CI 0.5 to 1.0). We were unable to confirm the reported increased risks of Wilms' tumor for those with high birth weights or with a maternal history of hypertension or fluid retention during pregnancy, nor did we find any association with mother's age at delivery, previous stillbirth, previous live birth, gestational length or height of the child.

- The aim of this study was to determine the risk of kidney cancer in 2 cohorts defined on the basis of hospital discharge diagnoses associated with analgesic or diuretic use during the period 1965 to 1983. Patients were followed up through 1984 for cancer incidence. After excluding cancers in the first year of observation, 161 kidney cancers were observed vs. 138 expected among 54,662 patients in the analgesics cohort. The relative risk was higher for women than for men. When examined by sub-site within the kidney, risk for cancer of the renal pelvis was similar in magnitude to that for the renal parenchyma. Among 115,616 patients in the diuretics cohort, 278 kidney cancers occurred vs. 209 expected. The risk for women was higher than for men. This elevation in risk was confined to cancer of the renal parenchyma, with no significantly increased risk seen for cancer of the renal pelvis. Although we observed little excess risk among members of the analgesics cohort, the significantly elevated risk among patients using diuretics supports a number of recent studies, but inability to adjust for confounding factors such as obesity preclude drawing any conclusion regarding diuretics. Further research is warranted to assess in detail the relationship between diuretic use and cancer of the renal parenchyma.

- The causes of renal cell cancer (RCC) are poorly understood. Besides smoking, obesity remains the only risk factor that is fairly well established. The association between obesity and RCC appears stronger and more consistent in women than in men. We investigated the question of whether this apparent sex difference could be explained by repeated weight changes (weight cycling), less physical exercise, or pharmacological treatment of obesity in women. Structured face-to-face interviews were carried out with 379 (70% of all eligible) incident cases of RCC and 353 (72% of eligible) controls. The relationships between RCC and adult height, weight, and body mass index (BMI), defined as weight/height, were analyzed. Odds ratios (ORs) were estimated through logistic regression. No association was found between adult height and RCC. In men, weight and BMI appeared at most to be weakly related to risk of RCC. In women, higher adult weight and BMI (usual, highest, and lowest) and also high BMI at ages 30, 40, and 50 years were consistently associated with a significantly increased risk of RCC. Women with an usual adult BMI in the top 5% had a nearly 3-fold increased risk of RCC [OR, 2.67; 95% confidence interval (CI), 1.02-7.01]. Compared with individuals with no weight-loss periods, 2 or more such periods implied an OR of 0.96 (95% CI, 0.32-2.90) in men and 3.87 (95% CI, 1.20-12.45) in women. Physical activity at work reduced the risk of RCC in men but not women. Regular use of diet pills containing amphetamine was associated with an increased risk of RCC (OR, 4.06; 95% CI, 1.35-12.22).(ABSTRACT TRUNCATED AT 250 WORDS)
