China News Service, June 2. According to Hong Kong Sing, lymphoma is one of the ten most common cancers in Hong Kong. It can be mainly divided into "Hodgkin's lymphoma" and "non-Hodgkin's lymphoma". crowd is more common.

The Chinese University of Hong Kong School of Medicine and the Association of Pacific Rim Universities cooperated to investigate the global distribution, risk factors and epidemiological trends of Hodgkin's lymphoma. The results show that the incidence of Hodgkin's lymphoma is generally higher in high-income countries or regions. Among them, the increase in the incidence rate of males in Hong Kong is the highest in the world.

  Symptoms of Hodgkin's lymphoma include painless swelling of the lymph nodes in the neck, weight loss, fever and night sweats.

Although rare, it is one of the most common cancers in the younger population.

According to the Hong Kong Hospital Authority, more than 60% of new Hodgkin lymphoma patients in 2019 were 44 years old or younger.

  The Faculty of Medicine of the Chinese University of Hong Kong, in collaboration with the Association of Pacific Rim Universities, collected data from international databases such as the Global Cancer Observatory, the World Health Organization Mortality Database, and the World Health Organization Global Health Observatory. The disease burden caused by lymphoma varies from place to place, with the highest incidence in Southern Europe and the highest mortality in Western Asia.

In addition, the Hodgkin lymphoma disease burden is directly proportional to per capita GDP, smoking rates, obesity rates, and prevalence of hypertension, implying that countries with higher levels of these associated risk factors generally have higher incidence and mortality rate.

  The study shows that the incidence of Hodgkin's lymphoma in the world has been on the rise in the past 10 years, and the upward trend in Asia is more significant. The incidence of males has the largest increase in Hong Kong (6.23), followed by the mainland (5.99) and Japan (4.54). ; The incidence of females has a more significant upward trend, with the largest increase in Ecuador (18.7), followed by Kuwait (17.8) and South Korea (8.08).

  There are regional differences in the incidence and mortality of Hodgkin's lymphoma, the researchers said, and may be related to the ability of detection and diagnosis, environmental factors, lifestyle and the prevalence of metabolic diseases.

The researchers also pointed out that the overall incidence of Hodgkin's lymphoma has shown an upward trend in recent years, but it is encouraging that its mortality rate has declined as treatment has become more popular and advanced.
