Cancer mortality in Illinois Mexican and Puerto Rican immigrants, 1979-1984

The site-specific cancer mortality in Illinois immigrant Hispanics for 1979-1984 was compared to that of US-born, non-Hispanic whites (Anglos). Using indirect methods of standardization, 22 site-specific cancer SMRs (Standard Mortality Ratios) were calculated for Mexican and Puerto Rican immigrants, using standard rates for Illinois Anglos. SMRs were also calculated for Puerto Rican immigrants using 1979-1982 mortality rates from Puerto Rico. Cancer mortality for all sites was lower in both immigrant groups than in Anglos. Colon cancer mortality risk was lower in immigrants, but had increased from home country rates in Puerto Rican male immigrants. In addition, immigrants retained their lower home country risks for cancer of the lung, prostate and female breast. Significantly higher risks were found in immigrant females only, for cancer of the stomach, cervix and gall-bladder (Mexican females). The cancer rates for immigrant Puerto Rican males were closer to those of Anglos than the rates for females and Mexicans, suggesting differences in the rates of transition to the Anglo cancer experience.     

Cancer mortality among Chinese, Japanese, and Indians in British Columbia, 1964-73

We compared age-adjusted mortality rates for cancer of selected sites for Chinese, Japanese, and native Indian residents of British Columbia during the years 1964-73 to the corresponding rates for the white population. Mortality from all cancers of the Chinese did not differ significantly from that of whites. Elevated rates are seen for cancer of the nasopharynx in both sexes, of the liver and esophagus in males, and of the lung in females. Chinese males had a lower mortality than whites from stomach, prostate, and bladder cancer and brain tumors, whereas females had a lower mortality from tumors of the colon, breast, and ovary; both sexes had a lower mortality from leukemia. For Japanese males and females, the mortality rates for all cancers combined were similar to those of the white population. The rates for cancer of the stomach and gallbladder were higher in both sexes; males also showed a higher rate of liver cancer. Prostate and breast cancer mortality rates were lower. Native Indian males had a lower mortality rate from all cancers combined; the difference was significant for stomach, colon, lung, and prostate cancers, and for leukemia. Native Indian females showed a lower rate for ovarian cancer and a higher rate of tumors of the gallbladder and uterine cervix, but their overall cancer mortality was similar to that of whites.     

Cancer incidence and mortality trends among whites in the United States, 1947-84

Cancer incidence trends from the late 1940s to 1983-84 were assessed among white residents of five geographic areas (Atlanta, Connecticut, Detroit, Iowa, San Francisco-Oakland) by means of data derived from several National Cancer Institute surveys, the Connecticut Tumor Registry, and the Surveillance, Epidemiology, and End Results Program. Incidence trends were compared with mortality trends for the entire United States and for the same five study areas. This study documented rising incidence and mortality rates for four cancers: lung cancer, melanoma of the skin, multiple myeloma, and non-Hodgkin's lymphomas. Increases in lung cancer continued through the early 1980s, but the rate of increase has been moderating during recent years, particularly among males and at younger ages for whom recent declines are evident. Overall, lung cancer incidence rates increased more than 220 and 400% among males and females, respectively. Although much rarer than lung cancer, melanoma of the skin and multiple myeloma increased greatly until the early 1980s among both males and females. The overall rate of increase in melanoma incidence among males was greater than that for lung cancer, and the rate of increase in multiple myeloma mortality among females was exceeded only by that for lung cancer. Increases of 70-120% were observed for non-Hodgkin's lymphomas. Increases in incidence and mortality rates for pancreatic cancer were apparent during the early years but less conspicuous in recent years. Laryngeal and kidney cancer rates generally increased substantially, although the changes were not remarkable for laryngeal cancer mortality among males and kidney cancer mortality among females. The rates for cancers of the mouth and pharynx increased among females but not males. Prostate, colon, and bladder cancer incidence rates increased more than 65% among males, whereas mortality rates changed only moderately. The incidence of thyroid cancer increased more than 75% among both sexes until the late 1970s, but mortality rates have declined during the period of study. Breast cancer incidence increased 30%, whereas mortality rates remained remarkably constant. The incidence of corpus uteri cancer increased dramatically during the mid-1970s and decreased substantially thereafter; these changes were not reflected in the mortality rates, which continually declined during the entire time period. The incidence of testicular cancer increased more than 90% and that of Hodgkin's disease did not change greatly; however, mortality rates for both cancers declined more than 50% since the late 1960s and early 1970s.(ABSTRACT TRUNCATED AT 400 WORDS)     

Increased childhood liver cancer mortality and arsenic in drinking water in northern Chile.

Arsenic in drinking water is an established cause of lung, bladder, and skin cancers in adults and may also cause adult kidney and liver cancers. Some evidence for these effects originated from region II of Chile, which had a period of elevated arsenic levels in drinking water, in particular from 1958 to 1970. This unique exposure scenario provides a rare opportunity to investigate the effects of early-life arsenic exposure on childhood mortality; to our knowledge, this is the first study of childhood cancer mortality and high concentrations of arsenic in drinking water. In this article, we compare cancer mortality rates under the age of 20 in region II during 1950 to 2000 with those of unexposed region V, dividing subjects into those born before, during, or after the peak exposure period. Mortality from the most common childhood cancers, leukemia and brain cancer, was not increased in the exposed population. However, we found that childhood liver cancer mortality occurred at higher rates than expected. For those exposed as young children, liver cancer mortality between ages 0 and 19 was especially high: the relative risk (RR) for males born during this period was 8.9 [95% confidence interval (95% CI), 1.7-45.8; P = 0.009]; for females, the corresponding RR was 14.1 (95% CI, 1.6-126; P = 0.018); and for males and females pooled, the RR was 10.6 (95% CI, 2.9-39.2; P < 0.001). These findings suggest that exposure to arsenic in drinking water during early childhood may result in an increase in childhood liver cancer mortality.     

Cancer patterns among Koreans in Japan, Koreans in Korea and Japanese in Japan in relation to life style factors

Cancer incidences for major sites were compared among Koreans in Osaka, Japan, Koreans in Korea and Japanese in Osaka by calculating standardized proportional incidence ratios (SPIR's), in addition to updating the findings on cancer mortality experiences of Koreans and Japanese in Osaka reported before. Compared with Japanese, Koreans in Osaka had significantly higher mortality rates from cancers of the esophagus, liver and lung in males, and liver in females. Mortality rates among Koreans in Osaka were significantly lower for stomach cancer in both sexes and for breast cancer in females. Compared with Korean counterparts in the homeland, Koreans in Osaka had a reduced risk for cancers of the stomach in males and the uterus in females. On the other hand, an elevated risk was observed for cancers of the esophagus, colon, liver and lung among Korean males in Osaka and for cancers of the colon and liver among Korean females in Osaka. The risk for cancer of the breast in females was similar among Koreans in the host and home countries. These different cancer patterns among Koreans in the host and home countries and Japanese are discussed in relation to their life styles, such as smoking, drinking and dietary habits, which have been investigated by means of questionnaire surveys.     

Cancer mortality in the USSR, 1986-88

Mortality rates in the USSR for the major cancer sites have been computed for the period 1986-88 from official numbers of certified deaths and population estimates provided by the World Health Organization databank, and compared with rates for 26 other European countries. Among males, elevated mortality rates (age-adjusted, world standard) were observed for cancer of the oral cavity and pharynx (6.6/100,000), oesophagus (8.4/100,000) and larynx (6.8/100,000). Mortality from cancer of the stomach (38.4/100,000 males and 16.5/100,000 females, for a total of 87,000 deaths per year) was the highest in Europe. Likewise, overall lung cancer rates among males (61.0/100,000, for over 77,000 deaths per year) were among the highest in Europe, and showed substantial rises over the last 2 decades. Lung cancer mortality in females was comparatively low (6.9/100,000), and increased only moderately. Rates for cancers of the intestine (14.6/100,000 males and 10.6/100,000 females) and of the female breast (12.9/100,000) were comparatively low as compared to most other European countries, and those for prostatic cancer (5.9/100,000) were the lowest registered in Europe. In contrast, mortality for cancer of the uterus (9.7/100,000) was among the highest in Europe, probably due to high mortality from cervical cancer. Priorities for cancer control in the Soviet Union are thus reduction of consumption of tobacco and alcohol, which largely explain the high rates for lung and upper digestive and respiratory sites, improvements in diet composition and food storage to reduce the substantial excess of stomach cancer, and rational screening for cervical cancer.     

Cancer mortality following X-ray treatment for ankylosing spondylitis

Mortality has been studied in 15,577 ankylosing spondylitis (AS) patients diagnosed between 1935 and 1957 in the UK, of whom 14,556 received X-ray treatment. By January 1, 1992 over half of the cohort had died. Among the irradiated patients, cancer mortality was significantly greater than expected from the national rates for England and Wales, with a ratio of observed deaths to expected (relative risk, RR) of 1.30, and significant increases individually for leukaemia, non-Hodgkin's lymphoma, multiple myeloma and cancers of the oesophagus, colon, pancreas, lung, bones, connective and soft tissue, prostate, bladder and kidney. Among the unirradiated patients, cancer mortality was lower than expected from national rates (RR = 0.79). Among irradiated patients, the RRs for leukaemia, lung cancer, and all other neoplasms all decreased significantly with increasing time since first treatment following an initial increase. By 35 years after first treatment, the radiation-related excess for lung cancer had completely disappeared, while for other neoplasms the RR remained significantly raised, although at a lower level than in earlier periods. Most irradiated patients received several courses of treatment within a 5-year period. Based on a 1 in 15 random sample, the mean total body dose received in this period was 2.64 Gy, with the heaviest dose to the vertebrae. A linear dose-response model for all neoplasms except leukaemia gave an excess RR of 0.18 Gy^?1 in the period 5–24.9 years after first treatment, which decreased significantly to 0.11 Gy^?1 in the period more than 25 years after first treatment. There was no evidence that a linear-quadratic model fitted the data better than a linear model. There were significant dose-response relationships individually for cancers of the lung, oesophagus, colon, pancreas, prostate, bladder and kidney. © 1994 Wiley-Liss, Inc.     

Cancer incidence and mortality in the Caribbean

Background: Nearly 10% of immigrants to the United States come from the Caribbean region. In this paper, we analyzed incidence and mortality rates of the major cancers in the Bahamas, Barbados, Cuba, the Dominican Republic, Haiti, Jamaica, Puerto Rico, and Trinidad and Tobago, and compared them with US patterns. Methods: We obtained age-standardized, sex-specific cancer incidence and mortality rates for cancers of the bladder, breast, cervix, esophagus, large bowel, liver, lung, pancreas, prostate, and stomach for 8 Caribbean countries and the United States from the GLOBOCAN program of the International Agency for Research in Cancer (IARC) and for the U.S. population from the Surveillance, Epidemiology, and End Results (SEER) Program of the NCI. Results: GLOBOCAN incidence and mortality rates for the overall United States were lower than but correlated with overall SEER rates. Based on GLOBOCAN data, the incidence and mortality rates of cancers of the breast, prostate, large bowel, and lung, and, among males, bladder cancer were lower in the Caribbean countries than the United States. Caribbean countries had higher rates of cancers of the cervix, esophagus, liver, and stomach. Haiti had the highest incidence and mortality rates of cervix and liver cancers. Jamaica and Haiti had the highest rates of stomach cancer. Conclusions: Cancer incidence and mortality in the Caribbean generally follow known patterns of association with economic development, infectious agents, and racial/ethnic origin. Studying these patterns and how immigration changes them may yield clues to cancer etiology. A better understanding of cancer incidence and mortality rates may help health policymakers to implement state-of-the-art treatment and preventive services for people of Caribbean descent both in their native countries and in immigrant communities in the United States.     

Time trends in cancer incidence and mortality in central Italy.

Time trends in cancer incidence and mortality represent an essential tool for monitoring the changes in population lifestyle and in the environmental risks and the effectiveness of the health system on cancer control in a specific area. During 1985-1997 82 506 malignant tumours were diagnosed in the Tuscany Cancer Registry, central Italy (about 1 200 000 inhabitants) and 54 979 cancer deaths registered in the period 1985-1999 by the Regional Mortality Registry were analysed. A statistically significant decrease in incidence was evidenced for stomach and gallbladder in both sexes, and for oesophagus, larynx and lung among males. Significant increases were documented for melanomas of the skin, kidney and non-Hodgkin's lymphoma in both sexes for colon, prostate and Kaposi's sarcoma among males and for breast, thyroid and multiple myeloma among females. Mortality decreased significantly for stomach and thyroid in both sexes and for oral cavity and pharynx, oesophagus, rectum, larynx, lung, bone, prostate, testis and Hodgkin's disease among males and colon, gallbladder and breast among females. Mortality increased for soft tissue, brain and multiple myeloma. In conclusion, most of these data can be explained as the effect of the modifications that occurred in smoking habits between the sexes and as the consequence of the primary and secondary prevention activities that are ongoing in the area.

Cause‐specific mortality in a Chinese chrysotile textile worker cohort

Chrysotile asbestos has continued to be mined and used in China, but its health effects on exposed workers have not been well documented. This study was conducted to give a complete picture about cause‐specific mortality in Chinese asbestos workers. A cohort of 586 males and 279 females from a chrysotile textile factory were prospectively followed for 37 years. Their vital status was identified, and the date and underlying cause of death were verified from death registry. Cause‐specific standardized mortality ratios by gender were computed with nationwide gender‐ and cause‐specific mortality rates as reference. Male workers were 11 years older, and had 6 years longer exposure duration than females; 79% in males and 1% in females smoked. In males, the mortality rate of all cancers doubled; both larynx and lung cancer were four‐fold, and mesothelioma was 33‐fold. In females, there was slightly excess mortality from lung cancer and all cancers, and significant increase in mesothelioma and ovarian cancer. Other significantly increased mortality was seen from cancers of thymus, small intestine and penis in males, and cancers of bone and bladder in females. In addition to asbestosis, mortality from pulmonary heart disease was significantly elevated in both genders. The data confirmed significantly excess mortality from mesothelioma in either gender, lung and larynx cancers in males, and ovarian cancer in females. A gender difference in mortality from lung cancer and all cancers could be mainly due to the discrepancies in age, exposure duration and smoking between the male and female workers.     

Cancer mortality in relation to monitoring for radionuclide exposure in three UK nuclear industry workforces.

Cancer mortality in 40,761 employees of three UK nuclear industry facilities who had been monitored for external radiation exposure was examined according to whether they had also been monitored for possible internal exposure to tritium, plutonium or other radionuclides (uranium, polonium, actinium or other unspecified). Death rates from cancer were compared both with national rates and with rates in radiation workers not monitored for exposure to any radionuclides. Among workers monitored for tritium exposure, overall cancer mortality was significantly below national rates [standardized mortality ratio (SMR) = 83, 165 deaths; 2P = 0.02] and none of the cancer-specific death rates was significantly above either the national average or rates in non-monitored workers. Although the overall death rate from cancer in workers monitored for plutonium exposure was also significantly low relative to national rates (SMR = 89, 581 deaths; 2P = 0.005), mortality from pleural cancer was significantly raised (SMR = 357, nine deaths; 2P = 0.002); none of the rates differed significantly from those of non-monitored workers. Workers monitored for radionuclides other than tritium or plutonium also had a death rate from all cancers combined that was below the national average (SMR = 86, 418 deaths; 2P = 0.002) but prostatic cancer mortality was raised both in relation to death rates in the general population (SMR = 153, 37 deaths; 2P = 0.02) and to death rates in radiation workers who had not been monitored for exposure to any radionuclide [rate ratio (RR) = 1.65; 2P = 0.03]. Mortality from cancer of the lung was also significantly increased in workers monitored for other radionuclides compared with those of radiation workers not monitored for exposure to radionuclides (RR = 1.31, 164 deaths; 2P = 0.01). For cancers of the lung, prostate and all cancers combined, death rates in monitored workers were examined according to the timing and duration of monitoring for radionuclide exposure, with rates of radiation workers not monitored for any radionuclide forming the comparison group. In tritium-monitored workers, RRs for prostatic cancer varied significantly according to the number of years in which they were monitored (2P = 0.03). In workers monitored for plutonium exposure, RRs for all cancers combined increased with the number of years in which they were monitored (2P = 0.04) and with the number of years since first monitoring (2P = 0.0003). There was little suggestion of systematic variation in RRs for workers monitored for other radionuclides in relation to the timing or duration of monitoring, nor did it appear that their raised rates of cancer of the lung and prostate were explained by external radiation dose. These analyses of cancer mortality in relation to monitoring for radionuclide exposure reported in a large cohort of nuclear industry workers suggest that certain patterns of monitoring for some radionuclides may be associated with higher death rates from cancers of the lung, pleura, prostate and all cancers combined. Some of these findings may be due to chance. Moreover, because of the paucity of related data and lack of information about other possible exposures, such as whether plutonium workers are more likely to be exposed to asbestos, firm conclusions cannot be drawn at this stage. Further investigations of the relationship between radionuclide exposure and cancer in nuclear industry workers are needed.     

Cancer incidence and mortality in Ontario First Nations, 1968-1991 (Canada)

Objective: To determine cancer incidence and mortality rates in Ontario First Nations (FN) people (native Indians) during 1968–1991 and to compare these with rates in the Ontario population. Methods: A cohort of 141,290 Ontario FN was created from registration files maintained by the Canadian government. Cancers and deaths were ascertained by linkage to the provincial cancer registry and mortality file, which also provided general population comparison data. Results: Cancer incidence was significantly lower in FN compared to the general population for all cancer (rate ratio (RR) = 0.72 for females; 0.62 for males), breast cancer (RR = 0.54), lung cancer in men (RR = 0.68), prostate cancer (RR = 0.57) and colorectal cancer (RR = 0.58 and 0.57 in men and women, respectively). Rates were significantly higher in FN for cervical cancer (RR = 1.73) and gallbladder cancer (2.05 and 2.20 in men and women, respectively). Incidence rates increased significantly in FN people between 1968–1975 and 1984–1991 for all cancer and for the major cancers (breast, lung, prostate and colorectal). Colorectal cancer rate ratios were significantly higher in 1984–1991 than in 1968–1975, indicating converging incidence rates. Patterns of cancer mortality were similar. Conclusions: These trends are compatible with a population in epidemiologic transition to the Euro-American disease pattern which is dominated by chronic diseases.     

Cancer mortality rates among first and second generation migrants in the Netherlands: Convergence toward the rates of the native Dutch population

This study investigates the difference in cancer mortality rates between migrant groups and the native Dutch population, and determines the extent of convergence of cancer mortality rates according to migrants' generation, age at migration and duration of residence. Data were obtained from the national cause of death and population registries in the period 1995-2000. We used Poisson regression to compare the cancer mortality rates of migrants originating from Turkey, Morocco, Surinam, Netherlands Antilles and Aruba to the rates for the native Dutch. All-cancer mortality among all migrant groups combined was significantly lower when compared to that of the native Dutch population (RR = 0.55, CI: 0.52-0.58). For a large number of cancers, migrants had more than 50% lower risk of death, while elevated risks were found for stomach and liver cancers. Mortality rates for all cancers combined were higher among second generation migrants, among those with younger age at migration, and those with longer duration of residence. This effect was particularly pronounced in lung cancer and colorectal cancer. For most cancers, mortality among second generation migrants remained lower compared to the native Dutch population. Surinamese migrants showed the most consistent pattern of convergence of cancer mortality. The generally low cancer mortality rates among migrants showed some degree of convergence but did not yet reach the levels of the native Dutch population. This convergence implies that current levels of cancer mortality among migrants will gradually increase in future years if no specific preventive measurements are taken.     

Mortality from all cancers and lung, colorectal, breast and prostate cancer by country of birth in England and Wales, 2001-2003

Mortality from all cancers combined and major cancers among men and women aged 20 years and over was compared by country of birth with that of the whole of England and Wales as the reference group. Population data from the 2001 Census and mortality data for 2001-2003 were used to estimate standardised mortality ratios. Data on approximately 399 000 cancer deaths were available, with at least 400 cancer deaths in each of the smaller populations. Statistically significant differences from the reference group included: higher mortality from all cancers combined, lung and colorectal cancer among people born in Scotland and Ireland, lower mortality for all cancers combined, lung, breast and prostate cancer among people born in Bangladesh (except for lung cancer in men), India, Pakistan or China/Hong Kong, lower lung cancer mortality among people born in West Africa or the West Indies, higher breast cancer mortality among women born in West Africa and higher prostate cancer mortality among men born in West Africa or the West Indies. These data may be relevant to causal hypotheses and in relation to health care and cancer prevention.     

Cancer mortality among sub-Saharan African migrants in France

Not only are there few data on sub-Saharan migrant populations, but relatively little information is available on cancer patterns in Africa. This report presents cancer mortality patterns among the 290,000 sub-Saharan African migrants in France. Risks of mortality from different cancers in migrants born in West, Central, East, and Other parts of Africa have been compared with that observed in the local-born population, using mortality data from the period 1979–85 and population data from the 1982 French census. Relative risks were adjusted for important confounding factors such as social class and area of residence. Compared with natives, overall mortality from cancer is lower in sub-Saharan African migrants. Higher cancer mortality risks, however, are observed among males for several sites: liver in Central and West Africans; bladder in West Africans; and non-Hodgkin's lymphoma in Other African migrants. For females, risks were elevated for nasopharyngeal cancers in Other African and liver in West African migrants. The results are, for the most part, consistent with the few available data on cancer patterns in Africa, and with the patterns observed in African migrants to England and Wales (UK).This work was undertaken during the tenure of a Research Training Fellowship awarded to Dr Bouchardy by the International Agency for Research on Cancer, Lyon, France.

Cancer mortality in Indian and British ethnic immigrants from the Indian subcontinent to England and Wales.

Risk of cancer mortality from 1973 to 1985 in persons born in the Indian subcontinent who migrated to England and Wales was analysed by ethnicity, and compared with cancer mortality in the England and Wales native population, using data from England and Wales death certificates. There were substantial highly significant raised risks in Indian ethnic migrants for cancers of the mouth and pharynx, gall bladder, and liver in each sex, larynx and thyroid in males, and oesophagus in females. There were also substantial raised risks in these migrants of each sex for non-Hodgkin''s lymphoma and myeloma. For the mouth and pharynx, and liver in each sex, and gall bladder in females, there were also raised risks of lesser magnitude in British ethnic migrants. For colon and rectal cancer and cutaneous melanoma in each sex, ovarian cancer in women and bladder cancer in men, there were appreciable significantly reduced risks in the Indian ethnic migrants not shared by those of British ethnicity. Appreciable raised risks in British ethnic migrants not shared by those of Indian ethnicity occurred for nasopharyngeal cancer in males, soft tissue malignancy in both sexes and non-melanoma skin cancer in males. In migrants of both ethnicities there were appreciable significantly raised risks in each sex for leukaemia and decreased risks in each sex for gastric cancer, for lung cancer except in females of British ethnicity and in males for testicular cancer. The results suggest the need for public health measures to combat the high risks of oral and pharyngeal cancers and liver cancer in the Indian ethnic immigrant population of England and Wales, by prevention of betel quid chewing and hepatitis transmission respectively. The data also imply that early exposures or early acquired behaviours in India, or exposures during migration, may increase the risk of leukaemia and reduce the risks of gastric and testicular cancers in the migrants irrespective of their ethnicity. Aetiological studies would be worthwhile to investigate the reasons for the sizeable decreased risk of colon and rectal cancer and increased risk of gall bladder cancer in each sex and the increased risk of thyroid and laryngeal cancer in males and oesophageal cancer in females of Indian ethnicity but not of British ethnicity who have migrated from the Indian subcontinent.     

Time trends in cancer mortality in Estonia 1965–1989

Mortality rates for cancer of all sites combined and for 12 selected sites or site groups in Estonia from 1965 to 1989 were studied to assess overall progress in controlling cancer. Between 1965–1969 and 1985–1989, age-standardized mortality (world population) increased by 12.0% among males and decreased by 5.1% among females. The changes in mortality for the age-groups 20–44, 45–64, and 65 and over were ?0.3%, 23.5% and 5.8% among males and 0.9%, ?7.0% and ?4.4% among females, respectively. In males, the most marked rise in mortality occurred for cancers of the oral cavity and pharynx, intestine and larynx. In females, the most rapid increase was observed for cancers of the lung, oral cavity and pharynx and breast. The decline in stomach cancer and cervical cancer mortality reflects worldwide trends. However, the noticeable increase in mortality rates for most of the sites indicates a need for strong preventive measures, particularly anti-smoking campaigns. In general, the time trends in mortality from all cancers combined demonstrate that in Estonia, over the last 25 years, no progress against cancer has been achieved.     

Twenty-first century cancer patterns in small island nations: Grenada and the English-speaking Caribbean

Purpose

Grenada is a small island nation of 105,000 in the Caribbean with one single general hospital and pathology laboratory. This study assesses cancer incidence on the island based on existing pathology reports, and compares the cancer mortality burden between Grenada and other Caribbean nations.

Methods

Age-adjusted overall and site-specific cancer “incidence” rates (based on pathology reports) and mortality rates were calculated and compared for 2000–2009. Next, mortality rates for a more recent period, 2007–2013, were calculated for Grenada and a pool of English-speaking, majority African-ancestry Caribbean island nations. Lastly, for direct mortality comparisons by cancer site, mortality rate ratios were computed using negative binomial regression modeling.

Results

The pathology reports alone do not suffice to calculate national incidence rates but cancer mortality rates are rapidly increasing in Grenada. The leading causes of cancer mortality were prostate and lung cancers among men, and breast and cervical cancers among women. Overall cancer mortality is significantly higher for both male and female Grenadians than their Caribbean counterparts: RR 1.43 (95% CI 1.32–1.55) and RR 1.26 (95% CI 1.15–1.38), respectively. High prostate and non-Hodgkin’s lymphoma rates are concerning.

Conclusions

Given the small existing cancer infrastructure, excessive mortality in Grenada compared to its neighbors may be disproportionately more attributable to low survival than a high cancer risk. Global solutions will be required to meet the cancer control needs of geographically isolated small nations such as Grenada.
