Background: Surgical treatment of pelvic tumors is extremely complex; because of the conformation of the bone and the proximity to vital anatomical structures it is difficult to obtain adequate oncological margins while preserving limb function. Furthermore, pelvic sarcomas generally have a worse prognosis compared to sarcomas of the appendicular skeleton with the same histology. Limb-sparing surgery should be performed only when clear margins can be achieved. Multidisciplinary approach and treatment in high volume centers are key to obtaining the best results. Methods: We retrospectively examined patients treated surgically for pelvic tumors, both primary and metastatic, at the “Clinica Ortopedica di Padova”. between 2015 and 2024. 78 cases were included. Patients were divided into three groups based on the type of surgery performed: amputation, resection and reconstruction, resection without reconstruction. Purpose of the study: Purpose of the study is to analyze and compare functional results, oncological results and major complications between the three groups. Results: Analysis of Kaplan-Meier curves did not reveal significantly different survival rates between the three groups. Functional outcomes, evaluated with the MSTS score, were higher after limb-sparing procedures. No statistically relevant differences were found between reconstructed and non-reconstructed patients. Major complications were frequent in all groups, especially wound healing problems. There was a higher incidence of complications in reconstructed patients, particularly infections and mechanical complications. Late complications were seen almost exclusively in this group. Furthermore, in reconstructed patients complications seem to have a higher impact on survival. Conclusions: surgical resection with adequate margins is the main treatment of pelvic tumors. In selected patients, internal hemipelvectomy has the same oncological results as amputation. Surgical approach and reconstruction type need to be individualized and chosen based on tumor and patient characteristics.
Background: Il trattamento dei tumori pelvici è estremamente complesso poiché, data la particolare anatomia ossea e lo stretto rapporto con strutture nobili, è difficile ottenere margini oncologici adeguati preservando la funzionalità dell’arto. Inoltre, i sarcomi del bacino sono generalmente associati a prognosi peggiore rispetto ai sarcomi degli arti dello stesso istotipo. La chirurgia “limb-sparing” dovrebbe essere eseguita esclusivamente nel rispetto della radicalità oncologica. Per ottimizzare i risultati è fondamentale un approccio multidisciplinare in centri di riferimento. Materiali e metodi: sono stati analizzati retrospettivamente i pazienti trattati chirurgicamente per tumori del bacino, sia primitivi che metastatici, presso la Clinica Ortopedica dell’Azienda Ospedale Università di Padova dal 2015 al 2024. Sono stati inclusi 78 casi. I pazienti sono stati suddivisi in tre gruppi in base al tipo di trattamento chirurgico eseguito: amputazione interileoaddominale, resezione senza ricostruzione e resezione con ricostruzione. Scopo dello studio: Lo scopo dello studio è analizzare e confrontare i risultati oncologici, funzionali e le complicanze maggiori tra i tre gruppi presi in esame. Risultati: Lo studio mediante analisi di Kaplan-Meier non ha rivelato differenze significative in termini di sopravvivenza tra i tre gruppi. I pazienti amputati hanno riscontrato MSTS score inferiori rispetto ai pazienti resecati; non sono state riscontrate differenze statisticamente significative nei due gruppi di pazienti resecati. In tutti e tre i gruppi è stato registrato un alto tasso di complicanze maggiori. Le più frequenti sono state le deiscenze di ferita. I pazienti ricostruiti hanno avuto un tasso di complicanze maggiore rispetto agli altri gruppi, in particolare sono andati incontro a complicanze tardive, oltre che a postoperatorie e precoci, e hanno sviluppato anche complicanze meccaniche, oltre a infezioni e deiscenze. Inoltre, in tale gruppo, il verificarsi di complicanze maggiori sembra avere una maggior incidenza sulla sopravvivenza. Conclusione: La resezione chirurgica con margini adeguati rimane il cardine del trattamento dei tumori pelvici. Le emipelvectomie interne consentono, in pazienti accuratamente selezionati, di ottenere risultati oncologici comparabili alle procedure demolitive. La scelta dell’approccio chirurgico e della strategia ricostruttiva deve essere individualizzata e basata su caratteristiche tumorali e condizioni del paziente.
