There are many validated tools to serve the clinician in these efforts, particularly for pain assessment. Multimechanistic pain syndromes are common in cancer patients. Cancer patients may experience nociceptive pain. They may also experience neuropathic pain due to chemotherapy-induced or cancer-related nerve damage. Analgesic choices must be guided by the pain mechanisms, nature, and severity of the pain, comorbid conditions, and patient characteristics. Long-acting opioid analgesics or fixed-clock dosing can eliminate end-of-dose analgesic gaps. The potential for opioid abuse is an important public health challenge but one that should not undermine the appropriate treatment of moderate to severe cancer pain. Abuse-deterrent opioid formulations can be useful. Care is needed for special populations of cancer patients dealing with pain, such as geriatric, pediatric, or obese patients. While morphine has long been the gold standard of oral opioid products, recent clinical trials suggest that oral hydrocodone and oral oxycodone may offer advantages over oral morphine. Patient adherence is crucial for adequate analgesia and patient education can promote adherence and manage expectations.</p>}, number={1}, journal={Journal of Cancer Research Updates}, author={Joseph V.
