Our analysis indicates substantial excess mortality among adults aged 20-64 in 2020 and in 2021 in Europe but does not support a sustained postpandemic increase in all-cause mortality. The estimates were sensitive to the choice of the baseline period and modelling approach, underscoring the importance of presenting results under multiple analytical assumptions.
In our integrated series of case-control studies conducted in Italy and Switzerland (324 oral, 397 pharyngeal, 271 oesophageal, 506 laryngeal cancers and 3,263 controls), individuals who also drank alcoholic beverages outside meals showed an increased risk compared to those who drank at meals only. At any alcohol intake level, subjects also drinking between meals showed a more elevated risk of developing an upper aero-digestive tract cancer than subjects drinking only at meals. After adjustment for potential covariates, and, after allowance for the number of daily drinks to adjust for different alcohol-intake levels, the odds ratios for subjects reporting drinking outside meals were 1.5 (95% confidence interval [CI]: 1.0-2.2) for oral, 1.8 (95% CI: 1.3-2.5) for pharyngeal, 1.7 (95% CI: 1.2-2.5) for oesophageal and 1.2 (95% CI: 0.9-1.7) for laryngeal cancers. Our findings show that drinking pattern with respect to food consumption may influence alcohol carcinogenesis in the upper digestive and respiratory tract. An "alcohol washing effect" by chewing and swallowing is suggested.

Abstract An association between adenomatous polyps of the large bowel and colorectal cancer has been reported, in the absence, however, of population‐based estimates of risk. Subjects with histologically confirmed first diagnosis of large‐bowel polyps notified to the population‐based Cancer Registry of the Swiss Canton of Vaud (about 600,000 inhabitants) during the calendar period 1979‐1990 were actively followed up to the end of 1990 for the subsequent occurrence of malignant neoplasms. Among 2,496 individuals with intestinal polyps, followed for a total of 10,310 person‐years at risk (6,201 among males and 4,109 among females), 150 malignant neoplasms were registered versus 152 expected. Thus, the standardized incidence ratio (SIR) for all cancers combined was 0.99. A significant excess was observed for colorectal cancer, with 35 cases observed (19 males, 16 females) versus 17.0 expected (SIR = 2.1; 95% CI: 1.5–3.0). There was also an excess, although not significant, for small‐bowel cancer (2 cases observed vs. 0.4 expected; SIR = 5.4). In none of the other cancer sites was SIR significantly or appreciably elevated: in subjects with colorectal polyps the SIR was 1.6 for stomach, 1.0 for lung, 0.9 for breast and 1.2 for prostate. The SIR of colorectal cancer was 3.1 in the first year since polyp registration, and declined thereafter to 1.8, in the absence, however, of any further trend with time since diagnosis. The cumulative risk of colorectal cancer in subjects with colorectal polyps was 2% at 5 years and 3% at 10 years. The quantitative estimates of this study are of interest for their population‐based nature, and are potentially useful for defining and targeting screening colonoscopy programmes.
