Use of Myeloma Patient Outcome Scale (MyPOS) to gauge the effectiveness of palliative management in patients with multiple myeloma: Experience from a large tertiary academic center in India

e24137 Background: A diagnosis of Multiple Myeloma (MM) can carry significant physical, social, functional and emotional repercussions. There is a lack of data on Baseline Quality of Life (QOL) in patients with MM and effectiveness of palliative management in the Indian context, especially after the advent of newer chemo-immunotherapeutic agents and autologous stem cell transplant (ASCT). Myeloma Patient Outcome Scale (MyPOS) is the first questionnaire developed specific for MM patients. Objectives and Methods: To evaluate symptom burden and quality of life in MM patients admitted to the medical oncology ward. To assess change in quality of life and symptoms as well as analgesic requirements on telephonic follow up after one and three months from index admission. After institutional ethical clearance, MM inpatients were prospectively enrolled. Clinical and treatment related details were recorded. MyPOS questionnaire was administered as well as a detailed pain assessment using Brief Pain Inventory (BPI) was carried out at baseline, 1 and 3 months. Results: 82 out of 100 MM patients consented for recruitment (Mean age- 52 +/- 9yrs; Male- 55%). Mean duration of the disease since diagnosis was less than 1 year (0.86 years), with a mean International staging system (ISS) score of 2. Up to half (37/82, 45%) of the patients received ASCT in addition to chemotherapy. The baseline Global MyPOS Score was 58 +/- 8.8 while the mean Pain severity (MPS) and interference (MPI) scores were 25+/-8 and 43+/-10 respectively. The most painful region was the back. Only Tramadol was sufficient for a small minority (6/82, 7.4%), most required oral morphine. Most patents had significant interval improvement in their pain and QOL scores with a p less than 0.01 on follow-up (MyPOS at 1 month and 3 month were 81+/-6 and 78+/-5, MPS were 21+/-13 and 17+/-1.1, MPI were 38+/-2.2 and 37+/-2.1 respectively). Conclusions: Adequate pain management can significantly improve quality of life in MM patients. Use of standardized questionnaires such as MyPOS is a quintessential tool for the palliative specialist in order to gauge therapeutic efficacy.
