‘Thou shalt not throw away a living thing’: A single-centre 10-year experience using the spare parts principle for complex sarcoma reconstruction

For aggressive limb sarcomas beyond reconstructive reach, an amputation may be the only alternative to achieve a complete tumour resection. However, very proximal amputations result in greater loss of function and quality-of-life impact. The spare parts principle advocates utilising tissues distal to the amputation site, for reconstructing complex defects and preserving the function. We aim to present our 10-year experience utilising this principle in complex sarcoma surgery. A retrospective review of our prospective sarcoma database was conducted for sarcoma patients treated with an amputation between 2012 and 2022. Cases in which distal segments were used for the reconstruction were identified. Demographic data, tumour characteristics, and surgical and non-surgical treatment, along with oncological outcomes and complications, were recorded and analysed. Fourteen patients were eligible for inclusion. The median age was 54 years at presentation (8-80 years) with 43% being females. Nine had a primary sarcoma resection, two were treated for recurrent tumours, two presented intractable osteomyelitis following sarcoma treatment and one had an amputation as a palliative procedure. The latter was the only oncological case in which tumour clearance was not achieved. Three patients developed metastasis and subsequently died during follow-up. Careful balancing of oncological goals and preservation of function is required for proximal limb-threatening sarcomas. When an amputation is required, tissues distal to the cancer site provide a safe reconstructive alternative, optimising patient recovery and preserving function. Our experience is limited by the small number of cases presenting with these rare and aggressive tumours.

Surgery for Pulmonary Metastases in Patients with Advanced Soft Tissue and Osteosarcomas

Background Advanced soft tissue or osteosarcoma is often associated with lung metastases. Curative pulmonary metastasectomy is appropriate for patients with successfully resected primary cancer who show no evidence of extrapulmonary metastases, with proven functional operability and completely resectable metastases. Material and Methods Systematic literature research and qualitative analysis of studies on patients undergoing lung metastasectomy after resection of primary sarcoma published since 01.01.2010. We assessed operative findings, survival data and prognostic factors. Results Pulmonary metastasectomy results in a median postmetastasectomy survival of 8.76 to 69.9 months. Five year survival rates after metastasectomy vary between 21.7 and 56.8%. The patients' prognosis depends particularly on complete resection of all suspected metastases. Intrapulmonary recurrence could be treated by repeated resection, but this procedure requires careful decision for indication. Re-metastasectomy might result in a favourable outcome in selected cases. Conclusion Pulmonary metastasectomy should be considered as treatment of choice in selected patients with isolated lung metastases from osteosarcoma. Optimal indication might lead to an advantage in patients with metastasectomy of isolated lung metastases from soft tissue.
