Upfront Surgical Resection for Osteosarcoma

Recruiting
Conditions
Osteosarcoma
Interventions
Other: Questionnaire
Registration Number
NCT06384404
Lead Sponsor
Montefiore Medical Center
Brief Summary

The goal of this pilot study is to learn about patients with newly diagnosed osteosarcoma of an extremity, and whether surgically removing the tumor prior to the administration of any chemotherapy will improve functional outcomes. In order to learn about the patient's experience, the study team will administer questionnaires to the patient and surgeon at various timepoints to assess recovery and the function of the extremity.

Detailed Description

This prospective, non-randomized pilot study will assess patient-reported functional outcomes of upfront surgical resection in patients with newly diagnosed, biopsy-proven, localized osteosarcoma of the extremity or the pelvis. Following biopsy, all patients will undergo wide excision of the tumor followed by systemic multi-agent cytotoxic chemotherapy consisting of a regimen at least equivalent to the standard of care of high dose Methotrexate, Doxorubicin, and Cisplatin (MAP). Patients and/or their parent/guardian will be administered PROMIS (Patient-Reported Outcomes Measurement Information System) questionnaires, while surgeons will be administered the Musculoskeletal Tumor Society (MSTS) questionnaire at various timepoints through the first year post-surgery.

Inclusion Criteria

  • Patients must have a performance status corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1, or 2 (Karnofsky will be used for patients >16 years of age and Lansky score for patients <= 16 years of age)
Exclusion Criteria
  • Patients with metastatic disease at diagnosis

Primary Outcome Measures
NameTimeMethod
Change in Health-Related Quality of Life (HRQoL) score from Historical Controlsapproximately 1 year

Modified age-based PROMIS measures will be used to assess HRQoL changes (PROMIS 25 Parent Proxy will be used for ages 5-7; PROMIS 25 for 8-17; PROMIS 29+2 for 18+)

PROMIS 25 (and PROMIS 25 Parent Proxy) contain six, 4-item short forms for domains: physical function mobility, anxiety, depressive symptoms, fatigue, peer relationships, pain interference; along with a pain intensity item. Scores for each domain range from 1-5 (pain intensity 0-10). Responses to individual items are coded to values and summed to generate a total raw score. Total raw scores are converted/rescaled into a standardized T-score for each participant with a mean of 50 and a standard deviation (SD) of 10. Higher PROMIS T-scores represent more of the concept being measured

PROMIS 29+2 is similar to PROMIS 25 with the exception of a social roles/activities domain in place of peer relationships, and also includes sleep disturbance and cognitive function domains. Scores are determined as described for PROMIS 25

Secondary Outcome Measures
NameTimeMethod
Event Free SurvivalUp to 2 years

The number of participants with event-free survival (EFS) will be determined. Event-free survival will be defined as the time from diagnosis until disease progression, recurrence at any site, secondary malignancy, death, or last follow-up, whichever is observed first
