BACKGROUND: Data and statistics are presented on cancer death certification for 1993 in Italy, updating previous publications covering the period 1955-1992. METHODS: Data for 1993 subdivided into 30 cancer sites are presented in 8 tables, including age- and sex-specific absolute and percentage frequencies of cancer deaths, and crude, age-specific and age-standardized rates, at all ages and truncated for the 35-64 year age group. RESULTS: Age-adjusted death certification rates (on the world standard population) for all neoplasms declined from 189.8 in 1992 (and a peak of 199.2 in 1986) to 187.8/100,000 males in 1993, and remained stable around 100,000 females. The favorable trends were even larger in middle and younger age males, but not in children below age 15, whose overall age-standardized cancer mortality rates increased for the fourth subsequent year. Lung cancer was the leading site of cancer mortality, with over 30,900 deaths. For the fifth subsequent year, its rates in males declined, to reach 56.0/100,000. The decline in lung cancer rates is now established in Italian males and is substantial in middle age, whereas the rise in female lung cancer rates seems to have leveled off over the last few years. Rates for other major cancer sites (intestines, stomach, female breast, prostate, pancreas, leukemias and lymphomas) were stable, but some decrease was apparent also in 1993 for Hodgkin's disease. CONCLUSIONS: Italian cancer mortality rates in 1993 were moderately favorable in males, due to the leveling of the tobacco-related epidemic, whereas no appreciable change was registered in females. The persisting unfavorable trends in childhood cancer mortality should be investigated.  相似文献

While numbers of papers on oral cancer in South Africa have been published, there have been very few studies on standardized morbidity rates. This paper has developed data collected by the National Cancer Registry from the entire country for the four year period 1988-1991 to present frequency, age standardized incidence rates (ASIRs) and life-time risk (LR) for histologically-diagnosed intra-oral cancers in female and male Asian, black, coloured and white South Africans. During this period 5396 cases of oral cancer were diagnosed in a total number of 157,307 cancer cases (3.4 per cent) excluding squamous cell carcinoma (SCC) and basal cell carcinoma (BSC) of the skin. Intra-oral cancer in all South African females and males accounted, respectively, for 1.8 per cent and 5.0 per cent of all cancers. There was a male preponderance in black, coloured and white groups but females were affected more frequently than men among Asians. The incidence in Asian women (6.66) was higher than those of the women in any of the other population groups, whereas the lowest incidence was found in black women (1.75). The incidence rate in coloured men was particularly high (13.13) whereas the incidence in white males (8.06) was not substantially lower than among black males (9.05). Differences between the eight groups were not significant (X2 = 6.24, df = 3, p > 0.1). The Cumulative Life Time Risk (LR) of developing intra-oral cancer for males and females in the four population groups ranged from 1:65 in coloured males to 1:455 for black females. Gender differences in LR in both black and coloured groups, signals substantial differences in exposure to known carcinogens for this disease. It is disturbing to note that the incidence in the period 1988-1991 was higher in Indian women that it was in 1964-1966, and that educative preventive measures have failed. Similarly, the incidence of intra-oral cancer in coloured men of 13.13 is substantially higher than the figure of 8.8 reported in 1979. If this is an accurately reflected trend, then a major educative programme needs to be pursued in this direction if the relative risk of one in 65 is to be reduced.  相似文献

BACKGROUND: Data and statistics are presented on cancer death certification in Italy, updating previous publications covering the period 1955-1993. METHODS: Data for 1994 and the quinquennium 1990-94 subdivided into 30 cancer sites are presented in 8 tables, including age- and sex-specific absolute and percentage frequencies of cancer deaths, and crude, age-specific and age-standardized rates, at all ages and truncated for the 35-64 year age group. Trends in age-standardized rates for major cancer sites are plotted from 1955 to 1994. RESULTS: The age-standardized (world standard) death certification rates from all neoplasms steadily declined from the peak of 199.2/100,000 males in 1988 to 186.3 in 1994, and in females from 102.5 in 1989 to 98.6 in 1994. Ever larger was the decline in truncated rates, for males from the peak of 275.1/100,000 in 1983 to 223.2 (-19%) in 1994, and for females from 151.6/100,000 in 1987 to 136.4 (-10%). A major component of the favourable cancer mortality trends in males was lung cancer (accounting for 31,000 deaths in both sexes combined in 1994), whose overall age-standardized rates declined from 60.3 in 1987-89 to 54.6/100,000 males in 1994 (-9%), and from the peak of 96.7 in 1983 at ages 35 to 64 to 72.7 in 1994 (-25%). In contrast, female lung cancer rates have remained stable from 1992 onwards, but have increased from 7.2 to 7.7 at all ages and from 10.6 to 11.0 at age 35-64 between 1985-89 and 1990-94. These different trends in the two sexes reflect the patterns and trends in smoking among Italian males and females. CONCLUSIONS: Cancer mortality trends in Italy over the period 1990-94 were relatively favourable, mainly reflecting the decline in lung cancer rates in males, together with the persistent declines in gastric cancer in both sexes and in cervix uteri for women. Continuous advancements were registered for neoplasms amenable to treatment, essentially testicular cancer, Hodgkin's disease and childhood leukaemias. The major unfavourable trends were observed for non Hodgkin's lymphomas, and require therefore further monitoring, besides a clearer understanding of their determinants. Italy maintains an intermediate level of cancer mortality on a European scale, suggesting that further progress is possible, mostly for tobacco-related neoplasms in males.  相似文献

The first results are presented of the newly established Netherlands Cancer Registry, which covers the whole Dutch population (approximately 15 million people). The registry receives data on incident cancer cases from nine autonomous regional cancer registries. Notification occurs primarily through the national registry of all pathology and haematology departments, with additional reporting by medical records' departments of all hospitals. Data on cancer patients are abstracted directly from the medical records by trained registration clerks. In the years 1989-1990, the most common cancer sites among males were cancers of the lung, prostate and colon. For females, breast cancer ranked first, followed by cancer of the colon and lung. A comparison with age-adjusted (world standard population) incidence rates reported by other western cancer registries showed a relatively high incidence of lung cancer among males (72.9 per 100,000) and breast cancer among females (76.2 per 100,000). Through its near completeness and the high quality of the registered data, the Netherlands Cancer Registry offers excellent opportunities for epidemiological and clinical research.  相似文献

BACKGROUND: Native Americans have been reported to have lower cancer incidence and mortality than other racial groups in the U.S., although some have questioned whether this was due to racial misclassification. This study provides improved estimates of cancer mortality, determined from a sampling of people who live on Indian reservations. METHODS: The authors reviewed death certificates from U.S. counties that contain Indian lands, excluding certain areas with known problems of racial misclassification. Age-adjusted mortality rates for specific types of cancer were calculated using U.S. Census population figures, and these rates were compared with rates for all races in the U.S. RESULTS: This sample included 38% of the American Indian and Alaska Native populations. The age-adjusted annual mortality rate for all cancers combined was 148.2 per 100,000 for both genders, 133.1 for females, and 167.2 for males. The rates for males and for both genders combined, but not for females, were significantly lower than the U.S. rates for all races (P < 0.05). Females had significantly lower rates of death from carcinoma of the lung and breast and significantly higher rates of death from carcinoma of the cervix and gallbladder (P < 0.05). Males had significantly lower rates of death from carcinoma of the lung, colon, and prostate, and significantly higher rates of liver carcinoma. Both genders combined had significantly lower rates of death from lung and colon carcinoma and significantly higher rates of death from stomach, liver, kidney, and gallbladder carcinoma. Geographic differences were substantial, with the Northern and Plains regions experiencing much higher mortality from lung, colon, and breast carcinoma than the Southwest region. CONCLUSIONS: Compared with the general U.S. population, Native Americans experience quite different patterns of cancer mortality. Cancer prevention and control programs should be designed specifically for this minority population.  相似文献

Our aim was to draw up a first general view of cancer pathology among the EDF-GDF women thanks to the cancer register among active employees created by the social security department of the French national electric and gas company EDF-GDF. Between 1978 and 1992, 764 cases of cancer were diagnosed. Breast cancer was the most common (52.4%), followed by gynaecological cancers: uterus (8.6%) and ovary (6.2%), and colon and rectum cancers (5.4%). The age-standardized breast cancer incidence using the 1978-1982 period as a basis increased over time. A higher incidence for breast cancer and a lower incidence for uterus cancer were observed among the EDF-GDF women during the 1978-1982 and 1983-1987 periods, compared to French women of same age. The study of the relationship between breast cancer risk and socioeconomic status, by means of indirect standardization, showed that the breast cancer risk increased with increasing socioeconomic status. Thus manual workers had a lower breast cancer risk than the EDF-GDF woman cohort (SIR = 0.72), foremen had the same risk (SIR = 1.05) and managers had a significantly higher risk (SIR = 1.64). Moreover a case-control study showed that the change in socioeconomic status between the beginning (20 years old) and the middle of a career (35 years old) was important but it was essentially the socioeconomic status at the beginning which determined the breast cancer risk. The results support the hypothesis of a "social class" effect through risk factors during the first part of the life.  相似文献

A comparative analysis is given of the gastric cancer incidence in the Tjumen Province for a period of 1959--1973. There was noted a direct dependence between the rate and number of risk factors (the complexes of unfavourable factors) in males and females. A conclusion is made that a higher incidence rate (1.7 times more) of gastric cancer among males may be attributed to the complexes of infavourable factors to which they are subject to a greater extent, 1.7 times as often as females, (mainly to bad habits) but not to biological features of the organism. Elimination of these harmful effects on the body would lessen the risk of this affection.  相似文献

The trends and current incidence of Creutzfeldt-Jakob disease (CJD) was examined by using a unique and potentially high sensitive source for case ascertainment. We analyzed death certificate information for 1979-1990 from US multiple-cause-of-death mortality data, compiled by the National Center for Health Statistics, Centers for Disease Control and Prevention. We evaluated death certificate data for US residents for whom CJD was listed as one of the multiple causes of death on the death certificate (046.1) from the International Statistical Classification of Diseases, Injuries, and Causes of Death (9th revision). Age-adjusted and age-specific CJD death rates by gender, race, and region were calculated to measure the disease incidence because of the rapidly fatal course of the disease for most patients with CJD. We identified 2,614 deaths with CJD listed on the death certificates. The average annual age-adjusted mortality rate was 0.9 deaths per million persons (range 0.8-1.1). The mean age at death was 67 years. CJD-related deaths were uncommon among persons younger than 50 years of age (4.3% of all deaths). The highest average annual mortality rate was for those persons aged 70-74 years (5.9 deaths per million persons). A slight majority (53.0%) of the deaths was in females, but the age-adjusted mortality rate was 1.2 times higher for males. Most deaths (94.8%) were in whites; the mortality rate for blacks was only 40% of that for whites. The age-adjusted CJD mortality rate in the United States is similar to published estimates of the crude incidence of CJD worldwide.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

The aims of the European Network of Cancer Registries (ENCR) are to improve the quality, comparability and availability of cancer registry data in Europe. This paper on cancer incidence and mortality in France presents the most recent available data, with short-term projections to 1995, and a commentary based, where possible, on epidemiological research carried out in France. Cancer incidence in men in France increased throughout the study period 1975 to 1995, from 92,000 new cases in 1975 to about 135,000 in 1995. This increase was partly due to the ageing of the French population, but incidence rates have also increased, particularly from 1975 to 1985. The trend appears to be levelling off in the 1990s, with an incidence rate in 1995 of about 482 per 100,000 (this and subsequent rates quoted are standardized to the European Standard Population). Among women, the all-cancer incidence rates also increased during the 1970s and 1980s. Although the rate of increase was less pronounced than in men, the trend is continuing in the 1990s. The estimated age standardized rate in 1995 was 309 per 100,000, representing 104,000 new cases. The main components of these changes in the last decade were, for men, increases in large bowel and prostate cancer, which have been partly compensated for by decreases in oral cavity, larynx and stomach cancer. For women the trend was dominated by the continuing increase in breast cancer with increases also in large bowel and lung cancers. Of the numerically important cancers in women, only stomach cancer has shown a clear decline. The situation in 1995 was that breast cancer remained the predominant cancer affecting women in France, accounting for almost one third of all new cases of cancer diagnosed and one fifth of cancer deaths. The next most frequent cancers in women were those of the large bowel. Regrettably, incidence rates of both breast and bowel cancer are increasing in women. For men in France the most frequent cancers in 1995 were those of the prostate, large bowel and lung, all of which increased in incidence since 1975. Although it is estimated that there will be more newly diagnosed cases of prostate cancer than lung cancer in 1995, the latter will cause many more deaths, particularly of young men.  相似文献

The role of indole in 2-acetylaminofluorene (AAF) bladder tumorigenesis was critically evaluated in hamsters. To avoid the influence of a nutritional factor on the tumor incidence, the animals were pair-fed for 8, 10, and 12 months. Addition of indole to the AAF diet resulted in a higher incidence of bladder tumors in both males and females (P less than 0.05, P less than 0.05). Indole definitely increased the bladder tumor incidence at 8 months (P less than 0.05). Also significantly different was the tumor incidence between males and females irrespective of the diet administered (P less than 0.05). Indole did not alter the urinary output of N-hydroxy-2-acetylaminofluorene (N-OH-AAF) in males.  相似文献

To measure the accuracy of incidence rates for invasive cervical cancer derived from cancer registration data, a review of histopathology records was undertaken for all cases of invasive cervical cancer, a 20 per cent random sample of CIN 3 registrations and all cases of cancer of the uterus not otherwise specified (NOS) from Greater Manchester, which were registered by the North Western Regional Cancer Registry between 1988 and 1989. The subjects were 386 cases of invasive cervical cancer, 313 CIN 3 registrations and 69 cases of cancer of the uterus NOS. The main outcome measure was the incidence rate of invasive cervical cancer in Greater Manchester after adjusting for errors in cancer registration. It was found that 375 (97 per cent) of the 386 cases of invasive cervical cancer were verified against the original pathology report but 11 cases (3 per cent) had been registered as invasive cervical cancer in error. Nine cases of invasive cervical cancer were found to have been misclassified as CIN 3, and 10 cases as cancer of the uterus NOS. As the CIN 3 cases were a 20 per cent random sample of all CIN 3 registrations, the best estimate of the number of cases of invasive cervical cancer misclassified as CIN 3 is 45, which makes a total under-registration of 55 cases over the two-year period. After adjusting for under-and over-registration, the incidence rate of invasive cancer of the cervix in Greater Manchester for 1988-1989 increased from 16.5 to 18.1 per 100,000 population.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

PURPOSE: We investigated the changing patterns of urogenital cancer deaths during the past 22 years in Japan. METHODS: We analyzed patients that died from cancer of the prostate, bladder and kidney between 1973-1994. Age-adjusted death rates (adjusted to the world population), standardized mortality ratios (SMR) according to each prefectures and age-specific death rates for each types of cancer were calculated and changes in these patterns were analyzed. RESULTS: Age-adjusted death rates for cancer of the prostate increased from 2.29 in 1973 to 4.36 in 1994, a 1.9-fold increase. Death rates for cancer of the bladder were stable in males and declined in females. Death rates for cancer of the kidney (15 years or older) increased from 1.45 in 1973 to 2.72 in 1994, a 1.9-fold increase in males, and tended to increase in females as well. In the SMR analysis by prefecture, distribution in 1973-84 (former period) and that in 1985-94 (later period) were similar, and characteristic features were observed for each type of cancer. Age-specific death rates for cancer of the prostate and bladder rose by an index power of age, but that for cancer of the kidney reached a plateau or decreased after an index power increase to a certain age. The rate of increase in age-specific death rates (later period/former period) rose according to age, especially 70 years or older, in cancer of the prostate and kidney in both males and females. However, age-specific death rates in the later period from cancer of the bladder was higher only in patients 85 years or older, but was lower in other age groups. CONCLUSIONS: Death rates for cancer of the prostate and kidney (15 years or older) tended to increase, while that of the bladder remained stable or decreased. It is expected that detection and treatment of these disease can be improved by utilizing these epidemiologic information.  相似文献

Blacks have the highest cancer incidences and mortality rates in the United States. Higher mortality rates appear due to higher incidence in some sites and to later-stage diagnoses in others. To address these problems, expanded cancer screening in an inner-city public hospital and a patient navigator intervention were proposed. Patient navigators acted as patient advocates for patients with abnormal screening findings. One thousand thirty-four females and 102 males were screened from July 1990 through November 1992; seven breast cancers and one cervical cancer were found. Patient navigators were significantly more likely to have seen patients with suspicious findings than patients with non-suspicious findings. However, even among those with suspicious findings, almost 70% were not seen by a patient navigator. Of those navigated, 87.5% completed recommended breast biopsies, compared with 56.6% of the non-navigated patients. Among those with a biopsy, navigated patients did so in significantly less time than those not navigated. Navigation is one of three phases proposed to reduce cancer mortality among medically underserved populations.  相似文献

PURPOSE: To assess the risk of subsequent malignant neoplasms among Hodgkin's disease patients diagnosed before 20 years of age in the five Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden). PATIENTS AND METHODS: There were 1,641 Hodgkin's disease patients identified through the national cancer registries since the 1940s or 1950s. The patients were monitored for 17,000 person-years until the end of 1991. Expected figures were derived from the age-specific incidence rates in each country and standardized incidence ratios (SIR) were calculated. RESULTS: A total of 62 subsequent neoplasms were diagnosed (SIR, 7.7; 95% confidence interval [CI], 5.9 to 9.9). The overall cumulative risk of subsequent neoplasms was 1.9% at the 10-year follow-up point, 6.9% at 20 years, and 18% at 30 years. There were 26 subsequent neoplasms among males (SIR, 6.5; 95% CI, 4.3 to 9.6) and 36 among females (SIR, 8.9; 95% CI, 6.2 to 12), of which 16 were breast cancers (SIR, 17; 95% CI, 9.9 to 28). High risks were seen for thyroid cancer (SIR, 33; 95% CI, 15 to 62), for secondary leukemia (SIR, 17; 95% CI, 6.9 to 35), and for non-Hodgkin's lymphoma (SIR, 15; 95% CI, 4.9 to 35). The relative risk increased from 3.3 (95% CI, 1.2 to 7.1) for Hodgkin's disease patients diagnosed in the 1940s and 1950s to 15 (95% CI, 7.4 to 27) in the 1980s. The highest risk of secondary leukemia (SIR, 68; 95% CI, 18 to 174) was seen among those diagnosed with Hodgkin's disease in the 1980s. CONCLUSION: Patients who survive Hodgkin's disease at a young age are at very high relative risk of subsequent malignant neoplasms throughout their lives. In particular, the high relative risk of breast cancer following Hodgkin's disease in the teenage years calls for enhanced activity for early diagnosis.  相似文献

Poisoning was reported as the underlying cause of death for 18,549 people in the United States in 1995 and was ranked as the third leading cause of injury mortality, following deaths from motor vehicle traffic injuries and firearm injuries. Poisoning was the leading cause of injury death for people ages 35 to 44 years. Poisoning death rates were higher in 1995 than in any previous year since at least 1979. From 1990 to 1995, the age-adjusted rate of death from poisoning increased 25%; all of the increase was associated with drugs. About three-fourths of poisoning deaths (77%) in 1995 were caused by drugs. The age-adjusted rate of drug-related poisoning deaths for males (7.2 per 100,000) in 1995 was more than twice that for females (3.0 per 100,000). From 1985 to 1995, poisoning death rates for males ages 35-54 years nearly doubled to 20.4 per 100,000, and the drug-related poisoning death rate for males ages 35-54 years nearly tripled, reaching 16.1 per 100,000. From 1990 to 1995, death rates associated with opiates and cocaine more than doubled among males ages 35-54 years. The numbers of opiate and cocaine poisoning deaths for 1995 more than doubled when all multiple cause of death codes were examined instead of only the underlying cause of death codes.  相似文献

A high-throughput phenotype screening protocol was used to measure the acoustic startle response (ASR) and prepulse inhibition (PPI) in mice. ASRs were evoked by noise bursts; prepulses for PPI were 70 dB sound pressure level tones of 4, 12, and 20 kHz. Forty inbred strains of mice were tested (in most cases using 10 males and 10 females of each strain). The data on both the ASR and PPI had high internal and test-retest reliability and showed large differences among inbred strains, indicative of strong genetic influences. Previously obtained measures of hearing sensitivity in the same inbred strains were not significantly correlated with ASR or PPI measures.

PURPOSE: Prostate cancer is the most frequently diagnosed cancer as well as the leading cause of cancer death among American Indian men. MATERIALS AND METHODS: To describe further the occurrence of prostate cancer among American Indian men, we examined population based incidence, treatment, survival and mortality data for American Indians in New Mexico during the 25-year period 1969 to 1994. RESULTS: Although American Indian men have a lower risk of prostate cancer than nonHispanic white men, the incidence and mortality rates are rising for American Indians, and mortality rates are now equal to those for nonHispanic white men. During the 25-year period age adjusted incidence rates for American Indians increased from 42.2/100,000 (95% confidence interval 27.1 to 57.3) to 64.6/100,000 (95% confidence interval 46.2 to 83.0). The burden of prostate cancer among American Indian men compared with nonHispanic white men was reflected in disproportionately high mortality rates in relation to incidence rates. The mortality rates were high because American Indian cases were more advanced at diagnosis, 23.3% of prostate cancers were diagnosed after distant spread had occurred compared with 11.6% for nonHispanic white men and the 5-year relative survival rate was poorer (57.1% compared with 77.6% for nonHispanic white men). CONCLUSIONS: Effective and culturally sensitive cancer control efforts for prostate cancer in American Indian communities are urgently needed.  相似文献
