日本語
To investigate the effect of (neo-)adjuvant chemotherapy for localized DLOS, we performed a systematic review of studies comparing mortality and event rates, including local recurrence and distant metastasis, among patients who underwent wide resection or wide resection and (neo-)adjuvant chemotherapy for localized DLOS without distant metastasis at diagnosis.

選択基準/Key inclusion criteria

日本語
We included only studies that reported mortality and event rates, such as local recurrence and distant metastasis, after surgery alone or surgery and (neo-)adjuvant chemotherapy for localized DLOS without distant metastasis at diagnosis.

除外基準/Key exclusion criteria

日本語
(1) Patients with distant metastasis at the time of DLOS diagnosis were excluded. Studies that did not specify mortality or event rates such as local recurrence or distant metastasis, or did not have a comparison group were also excluded. (2) Patients who underwent surgery alone for primary DLOS and received palliative chemotherapy for distant metastases that developed during the course of the disease were classified into the surgery-only group without adjuvant chemotherapy. (3) Only English- and Japanese-language literature was included, with no restriction on year of publication. Only human subjects were included and animals were excluded.

Data collection and presentation
Two authors (ST and TM) independently selected studies and extracted data. In case of any disagreement, agreement was reached between the two or the third author was consulted. The following data were collected using the data collection sheet. (1) Basic data: author, year of publication, journal name, type of study, follow-up period since diagnosis of DLOS, number of patients with localized DLOS (2) Number of patients who underwent surgery and (neo-)adjuvant chemotherapy for localized DLOS and the number of patients who had tumor death, local recurrence or distant metastasis. Number of patients who underwent surgery only for localized DLOS and the number of patients who had tumor death, local recurrence or distant metastasis. (3) Ratio of men to women, age, tumor site, tumor size, and subtype (parosteal or low-grade central osteosarcoma) of the original low-grade osteosarcoma, timing of dedifferentiation (synchronous or metachronous), surgical margins, adjuvant radiotherapy, and percentage of dedifferentiated areas, in the surgery plus (neo-)adjuvant chemotherapy group and the surgery alone group, respectively. (4) chemotherapy regimen, histological evidence of necrosis following preoperative chemotherapy (percentage of necrosis in the entire specimen, including low-grade component).
