A review of the literature on the pain experience of Chinese patients with cancer

Over 2 million new cases of cancer are diagnosed annually in China. In addition, cancer is the leading cause of death in China. Because cancer is often diagnosed in more advanced stages in China, a higher percentage of patients will experience pain related to their disease or treatment. This article presents a review and critique of the studies that examined the experience of pain in Chinese cancer patients. Because pain is a subjective experience with multiple dimensions, this review used the multiple dimensions of cancer pain to describe the pain experience in adult Chinese patients with cancer. The results from 24 studies of cancer pain in Chinese patients are summarized. Most of these descriptive correlational studies evaluated the physiologic and sensory dimensions of the pain experience. Most of the patients reported moderate to severe pain and that pain interfered with their normal activities and mood. In contrast, little information is available about the impact of cancer pain on the cognitive and sociocultural dimensions of the pain experience for Chinese patients.
