Cancer is one of the diseases that seriously threaten human health and life in today’s society, and palliative care for cancer pain has become a very important element in clinical medicine. The incidence of pain in primary cancer patients is about 25%, and the incidence in advanced patients is as high as 70%-90%. About 78% of the causes of pain are related to the tumor itself, and the invasion and metastasis of tumor pressing on bones, nerves and other organs are the most common causes of cancer pain. It is worth noting that some factors of psychological condition change, such as fear, anxiety, anger and loneliness, can also cause or aggravate cancer pain. Cancer pain is a kind of torture for both patients and family members. Only when pain is treated satisfactorily, patients’ quality of life and physical and mental status can be improved, and more effective treatment can be provided for the disease itself. In recent years, with the application of new generation of effective drugs to the clinic and the continuous improvement of pain relief technology, more and more patients with advanced cancer pain in China have been able to relieve their pain. Effective cancer pain treatment can improve patients’ quality of life, prolong their life expectancy, and reduce the psychological and economic burden of patients and their families. However, we are still far from the WHO goal of “making all cancer pain patients pain-free”, and cancer pain treatment in China still faces serious challenges at this stage. In order to truly and effectively reduce the personal pain of cancer pain patients, it is necessary to have a correct understanding of it. First, change the traditional thinking of cancer pain awareness and avoid avoiding the taboo of treatment. Many patients with cancer pain are unwilling to accept the fact of cancer, or even their families deliberately hide it with good intentions, coupled with some traditional thinking, such as “there is no tumor that does not hurt, especially advanced patients, pain is inevitable”, “cancer pain treatment is to take medicine and injections, to deal with it, there is no good solution”. There is no good way to deal with it” and other misconceptions. Some patients are unwilling or unable to express their pain, thinking that pain is a sign of cancer deterioration; discussing pain too much with doctors will reduce doctors’ time and energy for anti-tumor treatment; thinking that doctors do not like to hear patients complain about pain and want to be a “good patient”; not wanting to increase the worries of relatives, etc., so they tolerate pain as long as they can. As a result, about 70% of cancer pain patients do not receive standardized pain treatment, and suffer from great pain in silence with “coping treatment” or no treatment at all. Properly understand the side effects in treatment and avoid choking on them. One of the commonly used drugs in cancer pain treatment is opioid, and its representative drug is morphine. When morphine is mentioned, many of us may immediately think of its addictive side effects, and even draw a direct parallel with drugs and talk about it. In fact, modern medicine has been purifying and improving morphine-type drugs, for example, it is now possible to release morphine-type drugs slowly and orderly in the human body, which rarely produces euphoria and can overcome psychological addiction, and the possibility of addiction to morphine-type drugs is minimal as long as the drugs are administered in strict accordance with doctors’ instructions. As for the possible side effects of nausea, vomiting, drowsiness, constipation, urinary retention, etc., these drugs can be treated symptomatically and will not cause any major damage to the human body. Thirdly, choose the right treatment plan to achieve disease-specific treatment. The ideal cancer pain control goals are: good sleep at night, elimination of pain during quiet time and elimination of pain during physical activity, with the ultimate goal of improving patients’ life/survival quality. Therefore, the best treatment plan should be selected according to the pain level, pain location, disease progress and physical condition of cancer pain patients. The WHO three-step treatment plan is preferred for mild to moderate pain, and different combinations of drugs are used for different patients. The use of neurointerventional treatment for moderate to severe pain at an early stage is more effective in improving the overall level of pain resistance, which is of great significance in improving the quality of life of cancer patients. At present, the commonly used neurointerventional treatments include spinal nerve, sympathetic nerve and cranial nerve interventions, spinal cord electrical stimulation and central target-controlled analgesic system (intrathecal pump) implantation. The intrathecal pump implantation is a special catheter placed in the subarachnoid cavity, and the catheter is connected to the pump by subcutaneous tunneling, through the infusion system of the pump, morphine and other drugs can be continuously, slowly and uniformly injected into the cerebrospinal fluid of the subarachnoid cavity through the catheter. The dosage is equivalent to 1/300 of the oral dosage, which reduces the side effects caused by the systemic use of morphine. Fourth, maintain a healthy lifestyle and improve the quality of survival. After pain relief, patients should maintain a healthy lifestyle as much as possible, such as healthy diet, improved nutrition, moderate exercise, avoiding exposure to tobacco, alcohol and other harmful substances, and maintaining a good attitude towards life. After systematic and effective treatment, it is not a dream for cancer pain patients to enjoy better survival and quality of life.
