Trends in lung cancer incidence in Sweden with special reference to period and birth cohorts

Objective: Sweden has one of the largest population-based cancer registers in the world that provides an opportunity to examine the trend of lung cancer incidence during a 35-year period. The primary aim of the present study was to estimate the effects of birth cohort, year of diagnosis (period), and age on the time trends of lung cancer incidence rates, and to analyze the gender-specific incidence of different histopathological types of lung cancer. Results: Among men the age-standardized incidence rate increased steadily up to 1982, when a peak of 49 cases per 100,000 person-years was reached. Among women the incidence rate was lower and showed a monotonic increase throughout the observation period. The fastest rate of increase was noted among the youngest women. In women, but not in men, there was a steady increase in risk with each successive birth cohort. For both sexes there were large changes in the histopathological distributions of cases. The most notable was a major increase in adenocarcinomas. Conclusions: The overall age-adjusted incidence rate of lung cancer in Sweden has stabilized in men during the past two decades while rates are still increasing in women. In view of the continued high prevalence of smoking among young women, a future definite increase in the overall number of lung cancer cases in women can be expected.     

Global Patterns and Trends in Lung Cancer Incidence: A Population-Based Study

IntroductionLung cancer (LC) has been the most common cancer worldwide for several decades. This study comprehensively examines recent geographic patterns and temporal trends in LC incidence from 1978 to 2012 in 43 countries and evaluates the effects of birth cohort and period on temporal trends.MethodsData were retrieved from the Cancer Incidence in Five Continents database. Joinpoint regression and age-period-cohort models were applied.ResultsThe age-standardized rate was highest in Turkey (69.3 per 100,000 person-years) for men and in Denmark (36.7) for women in the period 2008 to 2012. Sex disparities were noted in most countries. From 1978 to 2012, a total of 19 countries had significantly declining trends among men, whereas 26 countries had significantly increasing trends among women (all p < 0.05). Quasi-reversed V-shaped and U-shaped incidence rate ratio trends indicating birth cohort effects were detected in 26 countries for men, with the highest risks mainly occurring in the 1930 to 1950 birth cohorts. However, the risks among recent generations have moderately increased in the People’s Republic of China and Japan for men and sharply increased in Lithuania, Belarus, and Republic of Korea for women. Incidence rate ratio increases were steep among earlier birth cohorts and gradual among the post-1930s cohorts in 15 countries for women. Period effects were more evident than birth cohort effects in five countries for both sexes.ConclusionsDisparities in LC incidence and carcinogenic risk persist worldwide. Our findings identified high-risk target populations for primary prevention to reduce the LC incidence and highlighted the urgent need for etiologic studies to identify the reasons for pronounced cohort-specific risk increases in certain countries.     

Screening for Gastric Cancer in Miyagi,Japan: Evaluation with a Population-Based Cancer Registry

Mass screening for gastric cancer originated in Miyagi Prefecture, Japan, in 1960. This review summarizes ‍studies assessing the efficacy of screening using data from a population-based cancer registry in the prefecture ‍that was started in 1959. Sensitivity and specificity of screening photofluorography (indirect radiography) is ‍81.1% and 88.8%, respectively. Ten-year survival rates are 30-40% better in screen-detected cases than in ‍symptom-diagnosed cases. No randomized controlled trials have reported the efficacy of the screening in the ‍country. In a 18-year follow-up study of 7,008 residents in the prefecture, incidence from gastric cancer did not ‍differ between screened and unscreened subjects, but mortality decreased significantly in screened subjects ‍compared with unscreened subjects for men (61.9 vs. 137.2 per 100,000 person-years, P<0.005) and women (28.1 ‍vs. 53.8 per 100,00 person-years, P<0.01). In a population-based case-control study with 198 cases and 577 ‍controls, odds ratio (95% confidence interval) of gastric cancer mortality was 0.41 (0.28-0.61) for ever vs. never ‍screened within 5 years. Studies conducted in other regions have provided similar findings. Substantial evidence ‍indicates that the Japanese screening program is effective in reducing the mortality from gastric cancer. ‍Population-based cancer registries play a crucial role in assessing the efficacy of cancer screening programs.     

Cancer incidence in Martinique: a model of epidemiological transition.

In this paper, we present data from the Martinique Cancer Registry for the period 1981-2000 and interpret cancer incidence trends in the light of risk factor patterns. In Martinique, cancer data are available from 1981. The sources of information are represented by insurance records, medical evacuations, hospitals and laboratory files. We performed a Mantel-Haenszel chi test stratified on age in order to assess time trends and to compare incidence rates between men and women over the whole period. A total of 8992 incidents of cancer cases were recorded during the last 20 years among men and 6832 in women. (The overall age-standardized incidence rate is 222 per 10 person-years for men and 145 per 10 person-years for women.) The most common cancers are prostate cancer in men (104 per 10 person-years) and breast cancer in women (42 per 10 person-years). Except for thyroid and salivary gland cancer, men experienced higher incidence rates for all other cancers. Incidence of prostate cancer in men, breast cancer in women and colorectal cancer in both sexes strongly increased between 1981-1990 and 1991-2000, whereas no significant variation was observed for that of all digestive cancers together. Among women, cervical cancer incidence strongly decreased. These results demonstrate that Martinique tends to have the same cancer risk profile as France Mainland with, however, higher incidence rates for cervical, stomach and prostate cancer. Changes in lifestyle and greater accessibility to diagnostic and therapeutic procedures, in particular screening, have strongly contributed to the 'epidemiological transition' observed.     

Cancer incidence and mortality patterns in women with breast symptoms in the mammography screening programme: A matched cohort analysis

Efforts to reduce mortality through early detection and diagnosis has intensified in the recent decade. An important risk factor, ‘breast symptoms’ reported by women during screening visit, remains overlooked. In this population based matched cohort study using Finnish National Breast Cancer Screening Program (FNBCSP), we assessed the association between breast symptoms reported at screening visit and the risk of cancer incidence and breast cancer mortality and all-cause mortality followed-up over a period of 24 years. For each visit with symptoms, non-symptomatic controls were matched (1:1 for lump and retraction; 1:2 for nipple discharge) based on age at screening visit, year of invitation, number of invited visits, and municipality of invitation. Women who reported lump or retraction had about two-fold risk of breast cancer incidence, three-fold risk of breast cancer mortality and all-cause mortality respectively as compared to women without respective symptoms (p-value<0.05). We found a substantial difference (p-value<0.05) in mortality rates throughout the follow-up period between symptomatic and asymptomatic group. In absolute terms, after the follow-up period for women who reported lump, 180 died from breast cancer as compared to 70 deaths in those without lump, per 10,000 person-years of follow-up, and 315 versus 160 all-cause deaths per 10,000 person-years in women with and without lump respectively. our study provides comprehensive evidence that women with breast symptoms remain in a higher risk of dying over a very long period. The findings indicate needs to develop improvements in the guidelines for screening and clinical services for women presenting with symptoms.     

Descriptive epidemiology of early and advanced gastric cancer in Ticino, Switzerland, with special emphasis on time trends

BACKGROUND: The main purpose of the study was to describe early gastriccancer (EGC) epidemiology in the population of Ticino, Switzerland(about 280,000 inhabitants) over the period 1981-1990, as comparedwith the epidemiology of overall gastric cancer (GC). PATIENTS AND METHODS: Incidence data were derived from the diagnosis data-file ofthe Cantonal Institute of Pathology. Numbers of certified deathswere abstracted from the registries of the Swiss Federal Officeof Statistics. RESULTS: The age-standardized (world population) incidence was 1.6/100,000males and 0.7/100,000 females for EGC (sex ratio: 2.3) and 19.8/100,000males and 9.1/100,000 females for GC (sex ratio: 2.2). Age-and sex-specific incidence rates for GC and for EGC showed similardistribution patterns. Mortality rates from GC declined overthe period considered by about 20% in both sexes, while incidencerates decreased by only about 7%, suggesting diminished lethality.There was a slight increase in EGC incidence, which was restrictedto men younger than 65 years and women older than 64 years. CONCLUSIONS: EGC incidence rates were less than 10% of advanced gastric cancerincidence rates for both sexes and most age groups. Early andadvanced gastric cancer had similar age and sex distributions.The downward trend in GC lethality over 1981–1990 wasnot entirely explained by the increase in the incidence of EGC. early gastric cancer, epidemiology, gastric cancer, incidence, mortality, time trends     

Lung cancer mortality trends in Canada from 1931 to 1982

Lung cancer is the leading cancer that causes premature death in Canadian men, and it is the second leading cancer that causes death in Canadian women. To assess the long-term mortality of this disease, we collected and analyzed data from 1931 to 1982. A 3-year base period was used to obtain person-years exposure using the Newton-Cotes method. All rates were standardized to the 1956 Canadian population for age and sex using the direct method. Standard errors of age-standardized death rates (ASDR) were computed using Chiang's method. The ASDRs have increased both for men and women. The increases in older age groups are due to a large, absolute increase in lung cancer-caused mortality in both sexes. Although the absolute increase in lung cancer is greater in men, the percentage of increase is greater in women, especially in the younger age groups. The mortality trends for lung cancer in both men and women appear to be consistent with the tobacco consumption in the population. Given the relatively low survival rates for lung cancer, preventive strategies are urgently required.     

Disparities in Epidemiological Profile of Gastric Adenocarcinoma in Selected Cities of Brazil

Background: Despite decreasing global incidence trends, gastric cancer is still among the five most incident cancersin the world and the third cancer-related cause of death. In Brazil, differences in incidence and mortality exist dependingon the geographic region studied. Objective: To describe the incidence, mortality, trends and age-period-cohort ofgastric cancer in three cities of Brazil (Sao Paulo, Belem and Fortaleza), in the period 1990-2012. Mortality for gastriccancer in Brazil overall and by region was described. Methods: 33,462 incident cases of gastric cancer were identifiedfrom the population-based cancer registries and 23,424 deaths from mortality information system in residents ofthe three cities and in Brazil were included in the study. Data for incident cases were extracted from the PopulationBased Cancer Registries from the National Cancer Institute (INCA). Mortality data on gastric cancer were extractedfrom Information Technology Department of Brazilian Public Health Care System/Health Ministry (DATASUS/MS).Mortality and incidence age standardized rates were calculated. For trends analysis the Joinpoint Regression andage-period-cohort model were applied. Results: Belem presented the highest incidence rates for gastric adenocarcinoma.Decreasing incidence trends were identified in Sao Paulo (-7.8% in men; -6.3% in women) and in Fortaleza (-1.2%in men). Increasing incidence trends were observed for women in Belem (1.8%) and Fortaleza (1.1%). In Belem(Amazon area), there was an increased risk for gastric cancer in women born after the 1960s. Overall in Brazil mortalityfor gastric cancer is decreasing. Mortality trends showed significant reduction, for both sexes, in the three Braziliancities. Conclusion: Incidence of gastric cancer is increasing in women born in the sixties in Belem (Amazon region)and Fortaleza (Northeast region). In Brazil there was increase in mortality in Northeast region and decrease in othersregions. More update data on incidence for Amazon and Northeast region is needed.     

Cancer mortality in Europe, 2005–2009, and an overview of trends since 1980

BackgroundAfter a peak in the late 1980s, cancer mortality in Europe has declined by ∼10% in both sexes up to the early 2000s. We provide an up-to-date picture of patterns and trends in mortality from major cancers in Europe.MethodsWe analyzed cancer mortality data from the World Health Organization for 25 cancer sites and 34 European countries (plus the European Union, EU) in 2005–2009. We computed age-standardized rates (per 100 000 person-years) using the world standard population and provided an overview of trends since 1980 for major European countries, using joinpoint regression.ResultsCancer mortality in the EU steadily declined since the late 1980s, with reductions by 1.6% per year in 2002–2009 in men and 1% per year in 1993–2009 in women. In western Europe, rates steadily declined over the last two decades for stomach and colorectal cancer, Hodgkin lymphoma, and leukemias in both sexes, breast and (cervix) uterine cancer in women, and testicular cancer in men. In central/eastern Europe, mortality from major cancer sites has been increasing up to the late 1990s/early 2000s. In most Europe, rates have been increasing for lung cancer in women and for pancreatic cancer and soft tissue sarcomas in both sexes, while they have started to decline over recent years for multiple myeloma. In 2005–2009, there was still an over twofold difference between the highest male cancer mortality in Hungary (235.2/100 000) and the lowest one in Sweden (112.9/100 000), and a 1.7-fold one in women (from 124.4 in Denmark to 71.0/100 000 in Spain).ConclusionsWith the major exceptions of female lung cancer and pancreatic cancer in both sexes, in the last quinquennium, cancer mortality has moderately but steadily declined across Europe. However, substantial differences across countries persist, requiring targeted interventions on risk factor control, early diagnosis, and improved management and pharmacological treatment for selected cancer sites.     

Trends in incidence of digestive cancers in France.

The objective of this study was to analyse trends in the incidence of digestive cancers in France. Observed incidence and mortality data in the population covered by cancer registries were modelled using age-cohort models. An estimation of the incidence/mortality ratio was obtained from these models and was applied to the mortality rates predicted from an age-cohort model for the entire French population. Site-specific standardized-incidence rates by 1-year intervals and cumulative rate 0-74 years by birth cohort were estimated. On average, age-standardized incidence rates of large bowel cancers increased by 1.0% per year in men and 0.8% in women from 1980 to 2000. The estimated cumulative rate increased from 4.0% for men born in 1913 to 4.8% for those born in 1953. The corresponding values in women were 2.5 and 2.9%. The most striking increase in incidence was seen for primary liver cancer with an increase from 2000 incident cases in 1980 to nearly 6000 in 2000. The estimated cumulative rate was 0.5% for men born in 1913 and 2.9% for those born in 1953. The increase in incidence was lower for pancreas cancer. A decrease in the incidence of stomach cancer was observed for both sexes and of oesophageal cancer in men by slightly more than 2%. The study showed large changes in the cancer burden in France between 1980 and 2000.     

Cancer incidence in Japan

Based on the estimates by the Research Group for Population-based Cancer Registration in Japan, time-trend of cancer incidence in Japan was described and analyzed. During the period of 1975-1998, the annual total cancer incidence increased 111,000-290,000 in males, and 96,000-208,000 among females. The higher incidence was prominent for cancers of the colorectum, lung, liver, gallbladder and extrahepatic bill duct (both sexes), prostate, and breast (female), whereas it was low or negligible for cancers of the stomach (both sexes) and uterus. The increased cancer incidence was globally attributed to the rapid growth of the Japanese aged population. However, a remarkable increase in the age-standardized incidence rate was also observed for cancers of the colorectum (both sexes), prostate, and breast (female). A decline in the age-standardized incidence rate was continuously observed for cancer of the stomach and uterus. A birth cohort analysis has revealed that the cancer incidence in Japan has been highly affected by the generation. Based on the Cancer Incidence in Five Continents Vol. VIII, the cumulative risk of cancer incidence (0-79 years old) was calculated and compared among the Japanese population (6 registries' data), US-Japanese and US-white. Several characteristics were suggested and discussed for Japanese cancer risk.     

Cancer risk in aluminum reduction plant workers (Canada)

A 14-year update to a previously published historical cohort study of aluminum reduction plant workers was conducted [1]. All men with three or more years at an aluminum reduction plant in British Columbia (BC), Canada between the years 1954 and 1997 were included; a total of 6,423 workers. A total of 662 men were diagnosed with cancer, representing a 400% increase from the original study. Standardized mortality and incidence ratios were used to compare the cancer mortality and incidence of the cohort to that of the BC population. Poisson regression was used to examine risk by cumulative exposure to coal tar pitch volatiles (CTPV) measured as benzene soluble materials (BSM) and benzo(a)pyrene (BaP). The risk for bladder cancer was related to cumulative exposure to CTPV measured as BSM and BaP (p trends <0.001), and the risk for stomach cancer was related to exposure measured by BaP (p trend BaP <0.05). The risks for lung cancer (p trend <0.001), non-Hodgkin lymphoma (p trend <0.001), and kidney cancer (p trend <0.01) also increased with increasing exposure, although the overall rates were similar to that of the general population. Analysis of the joint effect of smoking and CTPV exposure on cancer showed the observed dose–response relationships to be independent of smoking.

Thyroid cancer in Denmark 1943-2008, before and after iodine supplementation

Thyroid cancer incidence has increased worldwide during the previous decades. In this nationwide study, we aimed to identify the overall incidence of thyroid cancer in Denmark during 66 years (1943-2008) and incidences of the four main histological types of thyroid cancer from 1978 to 2008. Data were obtained from the nationwide Danish Cancer Registry, and we focused especially on the period after implementation of compulsory iodine supplementation, which was established on a national level in 2000. We calculated age-standardized incidence rates per 100,000 person-years, and age-period-cohort models were fitted to describe trends in incidence. To quantify trends in incidence over time, log-linear Poisson models were used to estimate annual percentage change. From 1943 to 2008, 1,947 men (29%) and 4,682 women (71%) were diagnosed with thyroid cancer. The age-standardized incidence increased in both sexes; in men from 0.41 to 1.57 per 100,000 and from 0.90 to 4.11 per 100,000 in women, corresponding to a significant average annual percentage change of 1.7 and 1.8%, respectively. The incidence increased with younger birth cohorts. The rise was almost exclusively caused by papillary carcinomas, and it was particularly present during the last decades of the study period. It cannot be ruled out that iodine supplementation may play a role for the risk of thyroid cancer, but as the strongest increase in incidence began in the years before the implementation, it is likely that improvement in diagnostic modalities increased diagnostic activity, and/or new unknown risk factors are also important contributors to the increase.     

Trends in incidence and overdiagnosis of thyroid cancer in China,Japan, and South Korea

We used data from 13 cancer registries in China, Japan, and South Korea to analyze time trends in overdiagnosis of thyroid cancer between 1998 and 2012. Age-standardized and age-specific incidence and annual percentage changes were calculated. The number of thyroid cancers diagnosed and the proportion attributable to overdiagnosis were estimated, with calculations stratified by sex and age group. The Spearman method was used to analyze the correlation between thyroid cancer incidence and overdiagnosis. From 1998 to 2012, both the incidence and proportions of overdiagnoses of thyroid cancer in China, Japan, and South Korea showed an increasing trend, with higher rates in women than men. South Korea had both the highest incidence for men (10.1/10⁵) and women (46.7/10⁵) and the highest proportions of overdiagnosis (men, 90.3%; women, 94.9%). The fastest growth in overdiagnosis was in Chinese men and women (annual percentage changes 6.1 and 4.6, respectively). We found significant positive correlations between age-standardized incidence and proportions of overdiagnosis for both men (Spearman r = 0.98, p < 0.05) and women (Spearman r = 0.99, p < 0.05) in the three countries. Age-specific incidence curves in Chinese and South Korean individuals were of an inverted U-shape. Overdiagnosis of thyroid cancer in Japan was mainly concentrated in middle-aged and older patients, whereas in China and South Korea, it occurred primarily in the middle-aged. The incidence and overdiagnosis of thyroid cancer in China, Japan, and South Korea are increasing, necessitating the implementation of comprehensive measures to reduce these overdiagnoses.     

Mortality from respiratory and digestive cancers among asbestos cement workers in Italy.

A cohort study is presented on the mortality of blue-collar workers in an asbestos-cement production plant that has been operating since 1907. Use of both crocidolite and chrysotile is reported. The cohort includes 2608 men and 759 women who were employed in the plant on Jan. 1, 1950 and those who started to work between 1950 and 1980. Follow-up was terminated on April 15, 1986 with 97.9% traced. Expected deaths were estimated from the age- and sex-specific regional mortality rates for the years 1969 to 1981. The data have been analyzed for the period 1964 to 1986 based on person-years at risk: 43,000 for men and 14,494 for women. A statistically significant increase was found in both sexes for mortality from all causes. From 1964 to 1986, 728 men died from all causes (608 expected), 275 with cancer at any site (158 expected) 110 with lung cancer (41 expected), 28 with pleural tumors (1 expected) and 85 with asbestosis (less than 1 expected). Corresponding figures for women were--all causes: 136 deaths versus 102 expected; all cancers: 79 verses 32 expected; lung cancer: 7 versus 2 expected; pleural tumor: 15 versus 0 expected and asbestosis: 4 versus 0 expected. Deaths from digestive tract cancer were in excess only among women (18 observed versus 10 expected, p less than 0.01). No excess was found for deaths from laryngeal cancer. Standardized mortality rates (SMR) for lung cancer among males showed a clear increase in direct relationship with length of follow-up. SMR according to length of employment were 234 for length 10 to 19 years, 363 for 20 to 29 years, and 256 for 30 years or longer (p less than 0.05 and lower).     

Trends in the incidence of gastric cancer in Japan and their associations with Helicobacter pylori infection and gastric mucosal atrophy

Background Although age-adjusted mortality from gastric cancer has been decreasing in Japan, the crude incidence of gastric cancer shows a slight increase.Methods We have observed trends in the incidence of gastric cancer by sex and 20-year age groups over the past two decades (1976–1996). Source data were obtained from the cancer statistics materials provided by the Research Group for Population-Based Cancer Registration in Japan. Simultaneously, we observed changes in the prevalence of Helicobacter pylori infection and in serological atrophy of the gastric mucosa, and compared the results with those involving changes in the incidence of gastric cancer.Results A slight decline was observed in all age groups over 40 years old, in both men and women, between 1986 and 1996. However, a marked decline in incidence was observed for those aged 20–39 years. The prevalence of H. pylori infection declined in both sexes between 1989 and 1998. The frequency of serological atrophy of the gastric mucosa significantly declined in all age groups between 1989 and 1996, with young age groups experiencing a more marked decrease.Conclusion The marked decline in gastric cancer incidence observed in the young population will also begin to occur in the elderly population in the future.     

Magnesium intake and primary liver cancer incidence and mortality in the Prostate,Lung, Colorectal and Ovarian Cancer Screening Trial

Epidemiological studies on magnesium intake and primary liver cancer (PLC) are scarce, and no prospective studies have examined the associations of magnesium intake with PLC incidence and mortality. We sought to clarify whether higher magnesium intake from diet and supplements was associated with lower risks of PLC incidence and mortality in the US population. Magnesium intake from diet and supplements was evaluated through a food frequency questionnaire in a cohort of 104,025 participants. Cox regression was employed to calculate hazard ratios for PLC incidence and competing risk regression was employed to calculate subdistribution hazard ratios for PLC mortality. Restricted cubic spline regression was employed to test nonlinearity. We documented 116 PLC cases during 1,193,513.5 person-years of follow-up and 100 PLC deaths during 1,198,021.3 person-years of follow-up. Total (diet + supplements) magnesium intake was found to be inversely associated with risks of PLC incidence (hazard ratio_{tertile 3 vs. 1}: 0.44; 95% confidence interval: 0.24, 0.80; p_trend = 0.0065) and mortality (subdistribution hazard ratio_{tertile 3 vs. 1}: 0.37; 95% confidence interval: 0.19, 0.71; p_trend = 0.0008). Similar results were obtained for dietary magnesium intake. Nonlinear inverse dose–response associations with PLC incidence and mortality were observed for both total and dietary magnesium intakes (all p_nonlinearity < 0.05). In summary, in the US population, a high magnesium intake is associated with decreased risks of PLC incidence and mortality in a nonlinear dose–response manner. These findings support that increasing the consumption of foods rich in magnesium may be beneficial in reducing PLC incidence and mortality.     

Cancer mortality in Europe in 2015 and an overview of trends since 1990

BackgroundCancer mortality in Europe has been decreasing since the late 1980s or 1990s in some countries with different patterns in many areas. In this study, we updated trends in cancer mortality in Europe.Materials and methodsWe extracted data from the World Health Organization mortality database for 24 cancer sites, 36 European countries and the European Union (EU) as a whole over the 1990–2017 period. We computed age-standardized death rates per 100 000 person-years, and we carried out a joinpoint regression analysis of mortality trends from all cancers and selected major neoplasms. The estimated annual percent change (APC) for each identified linear segment, and the weighted average APC (AAPC) over the entire study period were provided as summary measures of the changes in rates over the time period.ResultsIn 2015, the age-standardized mortality rates from all cancers in the EU were 137.5 deaths per 100 000 in men and 85.7 in women. Eastern European countries showed the highest rates with values over 150 deaths per 100 000 in men and over 100 deaths per 100 000 in women. Mortality from all cancers in the EU declined annually by 1.5% in men since 2006 and by 0.8% in women since 2007. Most cancer sites showed decreasing trends, with steady declines over the whole period for cancers of stomach, intestines, lung in men, breast and prostate. Unfavourable mortality trends persisted for cancers of liver, lung in women, pancreas, besides skin and kidney in men.ConclusionsThe downward trends in total cancer mortality in Europe still continue over the last decade. However, the trends were less favourable in most eastern European countries. Tobacco control in men (but not in women), improvements in diagnosis and therapy were the main underlying factors of these trends.     

The recent mortality and incidence rate of cancer of the nose, nasal cavities, middle ear and accessory sinuses

A case-control study was performed on cancer of the nose, nasal cavities, middle ear and accessory sinuses from 1982 through 1984 in Hokkaido. Maxillary sinus cancer accounted for 84% of this cancer in men and 87% in women. Histologically, squamous cell cancer was observed in 91% of the men and 83% of the women. The age-standardized incidence rates of this cancer were 1.3 per 100,000 for men and 0.4 for women. These figures were compared with the age-standardized mortality rates of this cancer for 1975 and 1980 by sex.
