Аннотация:Aim/BackgroundTo evaluate distribution of cancer patients at Sen Sok International University Hospital, Phnom Penh, Cambodia, according their place of residence, sex, age, cancer stage and types of malignant tumours.MethodsThe study performed at Sen Sok International University Hospital (SSIUH), a private teaching hospital, in Phnom Penh, Cambodia. Focus group: cancer patients visited SSIUH from 1.09.2010 until 31.07.2015.ResultsThere were 287 patients with cancer: 254 Cambodians (88.5%) and 33 foreigners (11.5%); the most of Cambodians live in Phnom Penh – 167 (65.7%), the most of foreigners are from Russian Federation - 8 (24.2%). Amount of males with cancer was more than amount of females -145 (50.5%) and 142 (49.5%); male / female (M / F) ratio was 1.02 / 1.0. Amount of Cambodian male cancer patients was less than amount of Cambodian female cancer patients - 124 (48.8%) and 130 (51.2%); M / F ratio was 1.0 / 1.05. Most of oncology patients had the III stage of cancer (40.42%). Percentage of cancer patients with advanced stages of cancer in Cambodians was 72.83%, in foreigners – 39.39%. 131 cancer patients (45.6%) are alive, 156 cancer patients (54.4%) died. Percentage of died patients was bigger among Cambodians (59.8%) than in foreigners (12.1%). Dominated cancers were: - in all oncology patients and in all male cancer patients – liver cancer (17.77% and 25.52%); - in all female cancer patients - breast cancer (16.20%); - in all Cambodian cancer patients and in Cambodian male cancer patients - liver cancer (18.90% and 27.42%); - in Cambodian female cancer patients – breast cancer (14.62%); - in all foreign cancer patients - breast cancer (12.13%); - in foreign male cancer patients - colorectal cancer and liver cancer (14.30% each); - in foreign female cancer patients - breast cancer (33.34%).ConclusionsThose Cambodian hospitals which organize diagnosis and therapy for cancer patients must have hospital cancer registries to collect an information about oncology patients include detailed data about cancer diagnosis and therapy. Detailed statistical analysis of information about cancer patients will help to improve cancer prevention, diagnosis and therapy in Cambodia. Reliable epidemiology data will be useful for worldwide cancer statistic.DisclosureAll authors have declared no conflicts of interest.
