Journal ArticleDOI
TL;DR: A population-based cancer registry, covering the province of Izmir (population 2.7 million, 1993-1994) in Western Turkey, provides much of the information required for planning strategies to control cancer.

TL;DR: The data indicate that cancers of the liver and cervix are the most prevalent cancers, and are likely to be due to infectious agents in The Gambia.
Abstract: We describe the incidence of cancer in The Gambia over a 10-year period using data collected through the Gambian National Cancer Registry. Major problems involved with cancer registration in a developing country, specifically in Africa are discussed. The data accumulated show a low overall rate of cancer incidence compared to more developed parts of the world. The overall age standardized incidence rates (ASR) were 61.0 and 55.7 per 100 000 for males and females, respectively. In males, liver cancer was most frequent, comprising 58% of cases (ASR 35.7) followed by non-Hodgkin lymphoma, 5.4% (ASR 2.4), lung 4.0%, (ASR 2.8) and prostate 3.3% (ASR 2.5) cancers. The most frequent cancers in females were cervix uteri 34.0% (ASR 18.9), liver 19.4% (ASR 11.2), breast 9.2% (ASR 5.5) and ovary 3.2% (ASR 1.6). The data indicate that cancers of the liver and cervix are the most prevalent cancers, and are likely to be due to infectious agents. It is hoped that immunization of children under 1 year against hepatitis B will drastically reduce the incidence of liver cancer in The Gambia.

TL;DR: The first results from the population‐based cancer registry for Blantyre district, Malawi, for the period 1994–1998 are reported, indicating that case‐finding outside the laboratory had been quite successful; nevertheless the rather low rates suggest possible underdiagnosis of cancer, as well as cases missed.
Abstract: In this paper, we report the first results from the population-based cancer registry for Blantyre district, Malawi, for the period 1994–1998. In this 5-year period, 1245 cases were recorded in males (an estimated age-standardized incidence of 92.0 per 100,000) and 1003 in females (an age standardised rate (ASR) of 88.8 per 105). The overall percentage of cases with histological verification was just 41.8%, indicating that case-finding outside the laboratory had been quite successful; nevertheless the rather low rates suggest possible underdiagnosis of cancer, as well as cases missed. As in other reports from the region, the contemporary pattern is dominated by Kaposi’s sarcoma (KS) (55.2% cancers in men, 28% in women), the effect of the evolving epidemic of AIDS. The incidence of cervix cancer in women is high (ASR 26.2 per 105), and there are moderately high rates of oesophageal cancer (ASR 15.4 per 105 in men, 9.3 per 105 in women). In childhood, the cancer profile is dominated by Burkitt’s lymphoma, which accounts for 42.4% of cancers; KS is now the second most frequent cancer of childhood.

TL;DR: The prognosis from colorectal cancer in Mumbai and developing countries, may be further improved through early detection linked with treatment, which seem to be related to differences in detection and treatment.
