What is the patient acceptance when only scapulectomy is possible in case of malignant tumor? A case series

BACKGROUND: Scapulectomy is one of the surgical options in the case of malignant lesions in the scapula with an indication of surgical removal. Very few series in the literature have looked at postoperative quality of life and emotional acceptance, particularly in the case of scapulectomy without reconstruction. The objective is to assess the midterm results of scapulectomies in terms of function, quality of life, and acceptance for the patient. METHODS: With a mean follow-up of 85 months (range 42 months-180 months), 11 scapulectomies for malignant tumors were performed with a mean age of 50 years: 5 partial scapulectomies, 4 total scapulectomies, and 2 subtotal scapulectomies. There were 6 chondrosarcomas, 2 high-grade osteosarcomas, 1 malignant peripheral nerve sheath tumor, and 1 low-grade atypical epithelioid sarcoma. The radio-clinical analysis was focused on functional results and mental health evaluation. RESULTS: The mean Musculoskeletal Tumor Society score of 11 scapulectomies was 20 ± 5 at 66% of normal, with the Disabilities of the Arm, Shoulder and Hand (DASH) score of 35 ± 26, and the Toronto Extremity Salvage Score of 76%. Patients had controlled pain (mean visual analog scale 1/10). Mobilities of the 11 scapulectomies were correct: average active anterior elevation of 89.5 ± 43 degrees, average abduction of 81 ± 42 degrees, average external rotation of 30 ± 25 degrees, and average internal rotation was at L5. Scapulectomy results in impaired physical and mental health compared with the general population (PCS-12 = -9; MCS-12 = -7). Partial scapulectomy, compared to total scapulectomy, gave better results: Musculoskeletal Tumor Society score (14 ± 1 vs. 24 ± 1 P = .0175), acceptance (45 ± 9 vs. 92 ± 16, P = .0184), mental health (MCS-12: 29 ± 1 vs. 55 ± 4, P = .0175), and Toronto Extremity Salvage Score (84 ± 5 vs. 68 ± 7, P = .0195). Partial and subtotal scapulectomies were better accepted (45 ± 9 vs. 86 ± 23, P = .0323) and tolerated (MCS-12: 29 ± 1 vs. 52 ± 6, P = .0099) by the patient compared to total scapulectomy. CONCLUSION: Total or partial scapulectomies without scapula reconstruction remain a disabling procedure performed with consequences on the physical and mental health of the patients. Partial or subtotal scapulectomy should be performed whenever possible because it seems to be associated with a better functional prognosis as well as less poor mental health and emotional acceptance of the patients, even though total scapulectomy may be necessary to obtain a complete curative tumor resection, which is the main goal.
