Cancer of asians in kenya

Cancer risks in Nairobi (2000-2014) by ethnic group

We investigated the ethnic differences in the risk of several cancers in the population of Nairobi, Kenya, using data from the Nairobi Cancer Registry. The registry records the variable "Tribe" for each case, a categorisation that includes, as well as 22 tribal groups, categories for Kenyans of European and of Asian origin, and non-Kenyan Africans. Tribes included in the final analysis were Kikuyu, Kamba, Kisii, Kalenjin, Luo, Luhya, Somalis, Asians, non-Kenyans, Caucasians, Other tribes and unknown. The largest group was taken as the reference category for the calculation of odds ratios; this was African Kenyans (for comparisons by race), and Kikuyus (the tribe with the largest numbers of cancer registrations (38% of the total)) for comparisons between the Kenyan tribes. P-values are obtained from the Wald test. Cancers that were more common among the white population than in black Kenyans were skin cancers and cancers of the bladder, while cancers that are more common in Kenyan Asians include colorectal, lung, breast, ovary, corpus uteri and non-Hodgkin lymphoma. Cancers that were less common among Asians and Caucasians were oesophagus, stomach and cervix cancer. Within the African population, there were marked differences in cancer risk by tribe. Among the tribes of Bantu ethnicity, the Kamba had higher risks of melanoma, Kaposi sarcoma, liver and cervix cancer, and lower risks of oesophagus, stomach, corpus uteri and nervous system cancers. Luo and Luhya had much higher odds of Kaposi sarcoma and Burkitt lymphoma.

A bibliography of the leukaemias in Africa, 1904-1985

A bibliography of leukaemias in Africa is presented from 1904 to 1985. The literature is listed chronologically and is classified geographically (north, south, east and west Africa) and by leukaemia type. The epidemiology of leukaemias in Africa is discussed briefly, especially as to the rarity of acute lymphoblastic leukaemia under the age of four years, the frequency of chloroma, the young age of presentation of chronic granulocytic leukaemia, the frequency of chronic lymphatic leukaemia in adults, especially women, under 45 years in tropical Africa, and the frequency of infection by the human T-cell leukaemia-lymphoma (or lymphotropic) virus type I and of adult T-cell leukaemia-lymphoma.

Patterns of gastro-intestinal cancer in European migrants to Australia: the role of dietary change

Cancers of the stomach, pancreas, colon and rectum are increasingly regarded as being diet-influenced. Migrants to Australia from England, Scotland, Ireland, Poland, Yugoslavia, Greece, and Italy have come from countries with varied dietary backgrounds and gastrointestinal cancer risks. Age-standardized cancer death rates in migrrants, by country of origin, sex, age, and duration of residence in Australia (less than or equal to 16 years and greater than 16 years), have been calculated for 1962-76, and compared with those of the Australian-born population. All seven migrant source countries, in 1970, had higher rates of stomach cancer than Australia, and the corresponding migrants groups, which initially reflected those higher rates, experienced an approximately 25% risk reduction with increased duration of residence. For cancer of the pancreas, migrants initially had rates well above their "native" rates; with longer stay, the risks generally converged upon that of the Australian-born population. The four "continental" (European) migrant groups, whose native risk of colon cancer is about half that of the Australian population, showed an increased risk with increasing duration of stay. The increase was greater in men than in women, perhaps reflecting their greater dietary acculturation. By contrast, Scottish migrants, with an initially high risk of cigrants showed even larger increases than colon cancer, while in British migrants there was a marked decline towards the "Australian-borne" risk. These various changes in cancer risk are discussed with reference to inter-country dietary differences.

Introductory statement on the progress of The National Large Bowel Cancer Project: its goals, objectives, and programs

The introductory lecture updates the state of the art bearing on cancer of the large bowel. Topics discussed include etiological factors, the pathology of the disease, the role of animal models, the early diagnosis of the disease, including biochemical markers, with emphasis on immunology, and finally therapy, including surgery, radiotherapy, chemotherapy, and the immunological approaches to therapy as identified in the ongoing activities of the National Large Bowel Cancer Project. Interesting aspects of complementing the traditional ways of treating colorectal disease are noted in the discussion of new approaches to chemotherapeutic treatment based on rational developments obtained throught the study of cell kinetics and cell turnover. It is pointed out that this and other interrelationships considered in the multidisciplinary experimental and clinical approaches provide important leads toward the understanding of the mechanisms of disease, discovery of causes and means of prevention, methods of earlier diagnosis, improved rational modalities of treatment, and, one hopes, more successful management.
