Factors associated with functional outcome in patients having limb salvage surgery for primary malignant bone sarcoma using TESS.
Abstract
INTRODUCTION\nAchieving maximum functional outcome in primary malignant bone sarcoma surgery (PMBS) patients, is challenging for both patients and clinicians. This study, aimed to evaluate different factors that affect postoperative functional outcome of the primary malignant bone sarcoma patients following upper limb (UL) and lower limb (LL) salvage surgery using Toronto Extremity Salvage Score (TESS).\n\n\nMETHODS\n136 PMBS adult patients were identified and were grouped as lower limb (LL) and upper limb (UL). Each group then sub-grouped to major and minor surgeries. Their functional outcome was compared using TESS by demographic variables(gender and age), neoadjuvant/adjuvant therapy and tumour variables (anatomical sites). In the UL groups, TESS was also compared for major and minor surgery subgroups based on their dominant or non-dominant limb.\n\n\nRESULTS\nThe result of TESS has revealed that chemotherapy, radiotherapy, and gender have no effect on the functional outcome in PMBS patients. Functional outcome however was significantly affected by age in both LL and UL groups. The TESS was significantly different between major and minor subgroups in UL group with p= 0.0001. In patients with upper LSS on their dominant limb, no significant difference between major/ minor surgery subgroups was observed with p=0.077.\n\n\nCONCLUSION\nOur findings using TESS revealed that factors such as patient s age, and type of surgery (major or minor) in PMBS patients will affect the patients functional outcome after LSS especially in those PMBS patients with upper LSS.
