Study population: We retrospectively reviewed medical records of 190 patients with high-grade sarcomas (mainly osteosarcomas and Ewing's sarcomas) that originated in bone, who received neoadjuvant chemotherapy from June 1, 2014, to March 1, 2017, at Peking University People's Hospital and Peking University Shougang Hospital.
Who may be able to join

- (3) patients who had primary tumor resection with assessment of histological response according to literatures;
- (4) patients who had intact pre- and post-neoadjuvant chemotherapy imaging, which included X-ray, contrasted computed tomography (CT), and magnetic resonance imaging (MRI) of the primary lesions as well as chest CT (with each layer ≤5 mm), bone scan, or [18F]2-fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET);

About this study
Official title: Clinical Evaluation of Neoadjuvant Chemotherapy for Primary Malignant Sarcomas That Originate in Bone: a Multi-center Retrospective Study for Standardization and Modification of Response Evaluation Criteria
For bone lesions treated with chemotherapy or targeted therapy, particularly for sarcomas that originate in bones, Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 is spurious because bone lesions are typically located in irregularly shaped bones, are difficult to measure accurately, and usually respond more slowly to treatment than soft tissue lesions. Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) allows for response to be measured in the absence of anatomic changes through assessment of metabolic activity. It does not, however, account for morphologic changes. This study evaluated whether clinical imaging findings of sarcomas after preoperative chemotherapy correlate with tumor responses by pathological evaluation using the rate of necrosis to develop reliable and quantitative clinical response criteria.
Read the detailed description
We reviewed a total of 190 primary lesions by clinical imaging, including X-ray, computed tomography (CT), magnetic resonance imaging, and bone scan or PET/CT in patients who received neoadjuvant chemotherapy. All patients had curative surgery of those lesions at Peking University People's Hospital or Peking University Shougang Hospital. Pathological evaluation was completed by determination of the tumor necrosis rate following Huvos' description. We also performed statistical diversity analysis for different pathological groups and generated receiver operating characteristic curves (ROC) to define the thresholds to distinguish different pathological groups.

What is being measured
The primary outcome is the main question the study is designed to answer.
Tumor necrosis rate
We evaluated all surgical resection specimens and were blinded to the clinical status. Upon histopathological examination, the tumor response was assessed on the basis of the presence and extent of necrosis, which was assessed by a combination of gross and microscopic observations. Tumor necrosis was graded as per Picci et al. tumor histopathological response grading (Huvos classification), where grade I is 0% to 49%, grade II is 50% to 89%, grade III is 90% to 99%, and grade IV is 100% necrosis.
Measured: 2-3 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
For bone lesions treated with chemotherapy or targeted therapy, particularly for sarcomas that originate in bones, Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 is spurious because bone lesions are typically located in irregularly shaped bones, are difficult to measure accurately, and usually respond more slowly to treatment than soft tissue lesions. Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) allows for response to be measured in the absence of anatomic changes through assessment of metabolic activity. It does not, however, account for morphologic changes. This study evaluated whether clinical imaging findings of sarcomas after preoperative chemotherapy correlate with tumor responses by pathological evaluation using the rate of necrosis to develop reliable and quantitative clinical response criteria.

Questions about this trial
What is this clinical trial studying?
An observational study of Clinical Response and Histopathological Response, run by Peking University People's Hospital at 2 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tumor necrosis rate (time frame: 2-3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03742063, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Apr 2019.
