- OBJECTIVE: The effect of alcohol intake on risk of NHL is unclear. We therefore conducted a population-based case-control study to examine the association between alcohol and NHL risk. METHODS: 613 NHL cases and 480 population controls in Sweden reported their average consumption of beer, wine, and liquor 2 years before the study. Unconditional logistic regression was used to estimate the odds ratios (OR) and corresponding 95% confidence intervals (CI) for associations between alcohol intake and NHL risk. RESULTS: Intake of total alcohol, beer, wine, or liquor was not associated with risk of overall NHL. There was no difference in risk of NHL among those who habitually consumed above 19.1 g of ethanol per day, compared to those who consumed on average 0-2.2 g of ethanol per day (OR = 1.2 (95% CI: 0.8, 1.7); Ptrend = 0.29). However, the association was significantly positive among males (OR = 1.8 (95% CI: 1.1, 2.9); Ptrend = 0.06). Total alcohol, beer, wine, or liquor intake was not associated with any major histopathologic subtype of NHL examined, apart from an association between high wine consumption and increased risk of chronic lymphocytic leukemia. CONCLUSIONS: Alcohol does not appear to be a major etiologic factor for overall NHL, nor its common subtypes.

- BACKGROUND: Infection with certain types of human papillomavirus (HPV), which is common among young women, increases the risk of cervical cancer. However, less than 1% of young women positive for oncogenic types of HPV develop cervical cancer. We investigated whether the amount of HPV DNA is a useful predictor of progression to cervical carcinoma in situ. METHODS: We estimated the amount of HPV 16 DNA by a PCR that uses the 5'-exonuclease (Taqman) method, in 478 women with cervical carcinoma in situ and 608 individually matched controls. To adjust for differences in the amount of genomic DNA between samples, we estimated the amount of a nuclear gene (beta-actin). We studied multiple smears (total 3835 archived samples) from each woman, taken over periods of up to 26 years, that covered normal cytology to development of cervical cancer. FINDINGS: The risk of cervical carcinoma in situ increased with the amount of HPV 16 DNA. Analysis of the first smear from each woman, collected a mean of 7.8 years before cancer diagnosis, showed that women with the 20% highest amount of HPV 16 DNA were at a 60-fold higher risk of developing cervical carcinoma in situ than women negative for HPV 16. The first smear samples were classified as normal by squamous-cell cytology. INTERPRETATION: Analysis of the amount of HPV DNA can predict cancer risk at a stage when current screening methods are uninformative. Testing for the amount of HPV 16 DNA during gynaecological health checks might strikingly improve our ability to distinguish between infections that have a high or low risk of progressing into cervical cancer.
