Postoperative Limb Function and QOL in Elderly Patients With Malignant Bone Tumor/Soft Tissue Sarcoma.

BACKGROUND/AIM:Malignant bone tumors (MBT) and soft tissue sarcomas (STS) require wide excision. Although the number of elderly patients is increasing, wide excision may decrease limb function and quality of life (QOL) for elderly patients. However, no detailed evaluation of the functional prognosis or QOL of elderly patients with sarcoma has been reported. This study evaluated postoperative limb function and QOL in elderly patients with MBT and STS. PATIENTS AND METHODS:This retrospective study included 67 patients aged >70 years with MBT or STS who underwent surgery at a single institution. The Toronto Extremity Salvage Score (TESS), EuroQoL 5-dimension 5-level (EQ-5D-5L) questionnaire, Musculoskeletal Tumor Society (MSTS) score, and psoas muscle index (PMI) were evaluated. We also assessed factors associated with the postoperative TESS and EQ-5D-5L index. RESULTS:Detailed examination of the MSTS items perioperatively revealed significant decline in manual dexterity/walking ability and support but significant improvement in pain and emotional acceptance. The mean PMI decreased significantly from 4.7 to 4.23 perioperatively. The postoperative mean TESS and EQ-5D-5L index was 76.9 and 0.74, respectively. Patients with good performance status and clinical frailty scale scores preoperatively had better postoperative TESS and EQ-5D-5L scores. CONCLUSION:The current study strongly suggests the possibility of maintaining postoperative limb function, satisfaction, and QOL in patients with MBT and STS by choosing patients in good condition and the appropriate procedure that the patient desires. However, perioperative progression of sarcopenia should be noted.
