After the pre-intervention evaluations are complete, patients will be randomized into one of two arms: treatment with cognitive behavioral therapy and narcotics as needed or treatment with conventional narcotic analgesics alone. Patients undergoing CBT intervention will participate in eight weekly therapy sessions. Follow-up assessments will be conducted six months and nine months after the last therapy session is completed. The patients will be evaluated based on pain score, narcotic dosage and frequency, anti-emetic usage, quality of life assessment, and pain related hospitalizations.
