Brief summary

Comparative study on surgery versus definitive radiation therapy in primary localized sacral chordoma

Detailed description

International, multicenter, comparative, open-label, parallel-group, mixed Observational-Randomized Controlled Trial. All the patients, who are candidate for the study will receive full information on the characteristics, potential effectiveness and side effects of the two alternatives treatments: radiotherapy (RT) and surgical treatment Eligible patients will be asked to be randomized in order to receive treatment A (surgery, with or without RT) or treatment B (definitive RT) Who will refuse randomization will be included in the Prospective Cohort Study (PCS) and will be treated accordingly to their choice (treatment option A or treatment option B). The same radiotherapy and surgical regimen will be administered in the PCS and in the Randomized Clinical Trial (RCT) cohort

Interventions

OTHERRandomized Cohort

Surgical treatment with different approach, based on the characteristics of the tumor or definitive high dose radiotherapy (carbon ion radiotherapy, proton-therapy, mixed photons-proton therapy) will be assigned by randomization

Surgical treatment or definitive high dose radiotherapy will be selected by the patients and will be prospectively evaluated

Inclusion criteria

* Histologically confirmed diagnosis (brachyury expression) of primary sacral chordoma,of any diameter and arising at any site from S1 to coccyx. * Age≥18years * ECOG-performance status (PS) 0-2 * No previous antineoplastic therapy * Macroscopic tumor detectable at MRI/CT scan * Patient amenable for surgery * Patient amenable for RT * Written informed consent given before the enrolment, according to International Conference on Harmonisation/good clinical practice (ICH/GCP).

Exclusion criteria

* Distant metastasis * Inability to maintain treatment position * Prior radiotherapy to the pelvic region * Prior therapy for sacral chordoma (including surgery, cryoablation, hyperthermia, etc) * Local conditions that increase the risk of RT toxicity (tumor ulcerated skin infiltration, non-healing soft tissue infection, fistula in treatment field) * Rectal wall infiltration * General conditions that increase the risk of RT toxicity (active sclerodermia, xeroderma pigmentosum, cutaneous porphyria) * Presence of a second active cancer (with the exception of non-melanoma skin cancer in-situ cervix neoplasia and other in-situ neoplasia) * Severe comorbidities resulting in a prognosis of less than 6 months * Inability to give informed consent * Other malignancy within the last 5 years * Performance status ≥ 2 (ECOG). * Significant cardiovascular disease (for example, dyspnea \> 2 NYHA) * Significant systemic diseases grade \>3 on the NCI-CTCAE v4.03 scale, that limit patient availability, or according to investigator judgment may contribute significantly to treatment toxicity * Women who are pregnant or breast-feeding * Psychological, familial, social or geographic circumstances that limit the patient's ability to comply with the protocol or informed consent
