Summary
Brief summary (as posted)
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.

- label
- Huvos group I
- description
- 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%.

- 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 II is 50% to 89%.

- description
- 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 III is 90% to 99%.
