Dr. Zhu from the Department of Oncology introduced that about 5.5 million people around the world suffer from cancer pain every day, 50% of mid-stage cancer patients are accompanied by pain, 70%-90% of advanced stage patients will experience pain, and 80% of cancer patients with suicidal tendency are related to severe pain. Cancer pain brings patients not only physical pain, but also loss of human dignity. In clinical practice, we often see patients rolling around on the floor when in pain, and some even committing suicide. In 1982, the World Health Organization proposed the “Three Steps of Cancer Pain Management Principles” and hoped to achieve the goal of eliminating cancer pain in 2000. However, more than half of the cancer pain patients in China still do not receive standardized pain relief treatment. The main reason is that many cancer patients, their families and health care workers have misconceptions, some of them think that cancer pain is natural and can only be endured; some of them have more concerns about the application of narcotic drugs and worry about addiction, which affects the use of drugs for cancer patients. The International Association for the Study of Cancer Pain has recently announced a worldwide campaign for the “World Year Against Cancer Pain” from October 20 this year to October 20, 2009. The Cancer Pain Clinic was established in accordance with this spirit and the urgent needs of cancer patients. The main tasks of the Cancer Pain Clinic are, firstly, to help patients build up their confidence in life through popularization of science, and to clarify that cancer pain is not natural, but treatable and should be treated; secondly, to provide professional guidance to cancer pain patients for reasonable and standardized treatment according to the World Health Organization’s three-step treatment plan for cancer pain; thirdly, to formulate individualized treatment plans according to the specific conditions of different patients, so as to achieve the best treatment effect with the smallest amount of medicine. . She said that as long as the WHO three-step treatment plan for cancer pain is strictly followed and standardized individualized treatment is provided according to different patients’ conditions, the pain of 85% of cancer pain patients can be effectively relieved, and the pain of more than 75% of advanced stage patients can be relieved. Patients with intermediate and advanced cancer can be completely free from pain and live with dignity and quality like normal people.
