Sex differentials in Swiss cancer mortality
No full textSwiss national cancer mortality statistics from 1951 to 1984 and survival rates from the Vaud Cancer Registry datafile over the period 1974-1980 were considered in terms of sex ratios. Overall age-standardized cancer mortality for population aged 35-64 showed only a moderate decline in males (from 230 to 221/100,000), but a substantial one in females (from 191 to 152/100,000). Mortality from most cancer sites (except gallbladder and thyroid) was persistently higher in males, the male/female ratio ranging between 1.2 for intestines, skin, brain and lympho-reticular neoplasms to about 2 for stomach or pancreas, up to 7-10 for lung and cancers related to tobacco and alcohol (mouth or pharynx, oesophagus). The sex ratio for lung cancer increased between the early 1950's and the mid 1960's, but noticeably declined thereafter, probably reflecting trends in smoking prevalence among subsequent generations of Swiss males and females. Less obvious is the substantial increase in the sex ratio for liver cancer (from 1.6 to 5.7), which was evident in younger middle age, too. Population-based cancer survival statistics indicated that for most common sites rates were appreciably higher in females than in males. Thus, better survival explains part of the advantage in cancer mortality for women. This can be related to earlier diagnosis, better compliance or responsiveness to treatment, although there is no obvious single interpretation for this generalized more favourable pattern in females
Childhood cancer in Switzerland: mortality from 1951 to 1984
No full textCancer mortality among children in Switzerland was analysed using (1) age-specific and age-standardized (0-14) rates from 1951 to 1984 and (2) comparison of observed numbers of deaths over the period 1960-1984 with expected one obtained by application of age-specific rates for the period 1951-1959 to the population structure of subsequent 5-year calendar periods. Certified mortality fell about 60% for leukaemias, 21% for lymphomas, 66% for Wilms' tumours, 40% for bone sarcomas and 30% for other and unspecified sites. Thus, the overall decline in childhood cancer mortality in Switzerland was around 45%, slightly more marked in females (-48%) than in males (-42%), and more pronounced in younger children (over 50% before age 5). This corresponds to an absolute number of about 50 deaths from childhood cancer per year avoided in the early 1980s as compared with expected numbers computed on the basis of rates registered in the 1950s (30 deaths per year for leukaemias alone). The estimated total number of deaths avoided during the whole period 1960-1980 was 820 (430 leukaemias alone). Trends in childhood cancer mortality persisted steadily downwards in the early 1980s, suggesting that further progress is being achieved in the treatment of these neoplasms
