[The role and status of standardized cancer pain management in comprehensive cancer care].

Standardized cancer pain management is an essential component of comprehensive cancer care. Pain is one of the most common and distressing symptoms in palliative care for patients with advanced cancer. Persistent pain severely impairs daily function and quality of life. The implementation of standardized cancer pain management, including standardized assessment, analgesic treatment, adverse effect management, follow-up, and end-of-life care, has significantly improved pain control and quality of life, with the goal of achieving optimal pain relief and preserving dignity throughout the disease course. However, several challenges remain, including inadequate attention, non-standardized assessment, uneven access to analgesics, and limited application of minimally invasive interventions. This review summarizes the current status, role, and key strategies of standardized cancer pain management, aiming to provide evidence for establishing standardized pain management systems and improving comprehensive cancer care.
