Understanding Cancer Pain and Controlling Pain: Focusing on Patients With Metastatic Urologic Cancer

ABSTRACT

Urinary tumors include cancers that commonly occur throughout the population, such as bladder cancer, kidney cancer, ureter cancer, and prostate cancer. The incidence of urological tumors in Korea is increasing. As the treatments of patients with cancer, such as operation, target therapy, immunotherapy, and gene therapy, are being developed, the life expectancy has been increasing. However, significant number of patients experience disease progression despite of existing treatments. Therefore, symptom direct treatment is crucial in oncologic era. Symptoms of patients with cancer vary but pain is one of the most common symptoms. Therefore, proper pain management is essential for the patients to improve the quality of life. Pain in cancer has as many complex pathological and physical characteristics as various tumor types. Both pharmacological and nonpharmacological interventions are important to address the full spectrum of cancer pain in patients. Many approaches to pain control, including opioid analgesics, radiation, and interventional care, are included in pain control therapy. Clinicians working with urinary tumors should be familiar with these pain control options. This review is intended to provide practical help to clinicians in treating patients with urological tumors. Updates to current knowledge and concepts of cancer pain management are included.
