Chest wall resection and reconstruction for primary chest wall sarcomas: Analysis of survival, predictors of outcome, and long-term functional status

Objectives: We aimed to analyze survival, predictors of outcome, and the long-term functional status of patients with a diagnosis of primary chest wall sarcoma who undergo chest wall resection and reconstruction. Methods: We analyzed a prospectively maintained database, including all patients operated on between 2008 and 2021. The primary outcome measures were overall and disease-free survival and analyses were employed to determine the risk factors for poor survival and recurrence. Results: One hundred thirty-nine patients were included, 55% were men. The majority (96%) had an R0 resection and 75.1% had no postoperative complications up to 30 days postprocedure; median length of hospital stay was 7 days (range, 6-10 days). Median overall and disease-free survival was 58.8 and 53.6 months, respectively. For those alive, at long-term follow-up, 80% had a Medical Research Council dyspnea score of 0 and Karnofsky index >80%. Survival and mortality rates were better in chondrosarcomas compared with nonchondromatous sarcomas (P < .05). Previous history of radiotherapy, previous history of cancer, the type of sarcoma (Ewing's or soft tissue), the need for adjuvant treatment and tumor grade were significant predictors of mortality and recurrence on univariate testing. Extended resection, a higher number of ribs removed, and the incidence of postoperative complications were significantly associated with a worse postoperative Medical Research Council dyspnea score. Conclusions: Careful patient selection and multidisciplinary decision making is crucial. This leads to clear resection margins, good overall, and disease-free survival and good functional outcomes.
