发展中国家基于人口的癌症存活率报告并不常见。在拉丁美洲，只有波多黎各癌症登记处公布了基于人群的生存数据。古巴国家癌症登记处对1976年、1982年和1988-1989年发生的病例进行了三次生存研究。本文涉及全球观察到的相对生存率估计在后者的研究。分析生存时间趋势。在1988-1989年期间，从最常见的癌症部位纳入了12 985例原发性癌症病例，不包括原位癌病例和8 900例“仅死亡证明”报告的病例（35.8%）。使用混合随访系统检查了截至1994年12月31日病例的生命状态，排除了2900例失访病例（11.2%）。各主要地盘的土地管制处所占的比例亦已列明，并与一九八二年的比例作比较。使用SPSS统计软件通过Kaplan-Meier方法估计观察到的存活率。Hakulinen的癌症生存研究计算机程序包（1988年）使用古巴人口的生命表估计了相对比率。通过使用对数秩和皮尔逊统计检验实现了按诊断年份的生存曲线的统计比较。全球结果按随访年份显示，并及时与国际值进行比较分析。1982/1988-1989年期间，结肠癌、前列腺癌和肺癌的存活率下降。与美国相比，前列腺癌显示出较低的5年相对存活率，但其观察到的比率与波多黎各相当。口腔癌和肺癌的数字与美国和欧洲的相应数字相若。乳腺癌和宫颈癌的发病率与欧洲平均水平和美国黑人的发病率相当。
Reports of population-based survival rates of cancer from developing countries are infrequent. In Latin America, only the Cancer Registry of Puerto Rico has published population-based survival data. The National Cancer Registry of Cuba has achieved three survival studies with cases incident in 1976, 1982 and 1988-1989. This article deals with the global observed and relative survival rates estimated in the latter study. Survival time trends are analysed. In the period 1988-1989, 12,985 primary cancer cases were included from the most common cancer sites, with the exclusion of cancer in situ cases and 8900 cases reported by `death certificate only' (DCO) (35.8%). The vital status of cases was checked up to 31 December 1994 using a mixed follow-up system with the exclusion of 2900 cases lost to follow-up (11.2%). DCO proportions are shown for the major sites and compared to those of 1982. Observed survival rates were estimated by Kaplan-Meier method using the SPSS Statistical Software. The relative rates were estimated by the Hakulinen's Computer Program Package for Cancer Survival Studies (1988) using life tables from Cuban population. Statistical comparisons of survival curves by year of diagnosis were achieved by using the Log-Rank and Pearson statistic tests. Global results are shown by year of follow-up and a comparative analysis is done in time and with internationals values. Survival rates decreased in the period 1982/1988-1989 for colon, prostate and lung cancer. Prostate cancer shows a low five years relative survival rate when compared with the USA, but its observed rate is comparable with Puerto Rico's. Figures for mouth and lung cancer were comparable with the corresponding figures of the USA and Europe. Breast and cervix cancers rates are comparable with the European mean and the blacks in USA.
