The cooperation between professional societies contributes to the capacity building and system development for prevention and control of cancer in low- and middle-income countries: the practice of Cervical Cancer Prevention and Control Project in Cambodia.

Globally, an estimated 570,000 women are newly diagnosed with cervical cancer, and 311,000 women die every year, with approximately 90% of the cases occurring in low- and middle-income countries (LMICs). Cervical cancer is the most common cancer in women in Cambodia, with age-standard incidence rate of 13.5/100,000 and mortality rate of 10.1/100,000. This paper introduces the educational and managerial interventions of Cambodia Cervical Cancer Project 2015-2018 by two professional societies of Cambodia and Japan. It can be categorized into three phases: health education and screening; diagnosis and treatment of precancerous lesions; and pathology service. Human papillomavirus test-based cancer screening and treatment of precancerous lesions were successfully initiated. Key factors contributed to optimal outcomes are partnership between two professional societies with strong commitment, and a comprehensive and stepwise quality-focused approach. A complementary role and joint society initiatives is a novel approach and substantial in sustainability for developing a system of cervical cancer management. This effort might serve as a good example how professional societies can contribute to capacity building and system development for prevention and control of cancer in LMICs. 2020, National Center for Global Health and Medicine.
