2. For the 86 countries of the world (mainly in the developing regions) for which no vital statistics were available (Table 3), we estimated cancer mortality using the estimated incidence and age-, sex- and site-specific survival probabilities. In the previous set of estimates9,10 we used region-specific survival data, so that the cancer mortality for almost all the countries in developing regions were computed using the same set of survival probabilities. For GLOBOCAN 2008, survival was modeled based on GDP per capita. However, as described earlier in the results section, the most frequent cancers in the regions concerned (liver, lung, stomach oesophagus) have a poor prognosis, so that the differences in survival are rather small, particularly in men, although they are larger in women, in whom breast and cervical cancers predominate.
