Population-based cancer registries from Algeria, China, Costa Rica, Cu
ba, India, the Philippines, and Thailand are collaborating with the In
ternational Agency for Research on Cancer in a study of cancer surviva
l in developing countries. Comparisons with the SEER program results o
f the National Cancer Institute in the United States, and the EUROCARE
study of survival in European countries revealed considerable differe
nces in the survival of patients with certain tumors associated with i
ntensive chemotherapeutic treatment regimes (Hodgkin's disease and tes
ticular tumors), more modest differences in the survival of patients w
ith tumors for which early diagnosis and treatment confer an improved
prognosis (carcinomas of the large bowel, breast, and cenix), and only
slight differences for tumors associated with poor prognosis (carcino
mas of the stomach, pancreas, and lung). With limited resources to mee
t the challenge of the increasing incidence of cancer expected in the
next few decades, health authorities in developing countries should be
aware of the importance of investing in a range of cancer control act
ivities, including primary prevention and early detection programs as
well as treatment. (C) 1996 American Cancer Society.
