Control-Arm phase III high-risk CINSARC:

Patients will be treated by doxorubicin (60 or 75mg/m² day or 20- or 25 mg/m² per day from day1 to day 3) + ifosfamide (7,5-9 g/m² over 3 days with mesna and G-CSF) or dacarbazine (100 mg/m² 1 day or 450 mg/m² 2 days) as per local practices of a 21-days cycle for up to 3 cycles in neoadjuvant setting Neoadjuvant chemotherapy will be followed by surgery. If indicated, radiotherapy could be prescribed at the discretion of the investigator (in neoadjuvant or adjuvant setting).

Experimental-Arm phase III high-risk CINSARC:

Patients will be treated by doxorubicin (60 or 75mg/m² day or 20 or 25 mg/m² per day from day1 to day 3) + ifosfamide (7,5-9 g/m² over 3 days with mesna and G-CSF) or dacarbazine (100 mg/m² 1 day or 450 mg/m² 2 days) as per local practices of a 21-days cycle for up to 6 cycles in neoadjuvant setting Neoadjuvant chemotherapy will be followed by surgery. If indicated, radiotherapy could be prescribed at the discretion of the investigator (in neoadjuvant or adjuvant setting).

Patients will be treated at the discretion of the investigator

A treatment cycle consists of 3 weeks. Doxorubicin will be administered from day 1 to day 3 (60 or 75mg/m² day or 20 or 25 mg/m² per day), repeated every 3 weeks, up to 3 cycles.

A treatment cycle consists of 3 weeks. Treatment may continue up to 3 cycles. Ifosfamide will be administered from day 1 to day 3 (7,5-9 g/m² over 3 days with mesna and G-CSF) or dacarbazine (100 mg/m² 1 day or 450 mg/m² 2 days) as per local practices, repeated every 3 weeks, up to 3 cycles.

The primary objective of this trial is to investigate whether the addition of 3 additional neo-adjuvant cycles of chemotherapy (doxorubicin based chemotherapy) to standard management according to the ISG-STS 10-01 study (3 cycles of neoadjuvant doxorubicin based chemotherapy + surgery +/- radiotherapy) improves the outcome of high-risk CINSARC patients with resectable soft-tissue sarcoma (STS). Primary endpoint is metastatic progression-free survival (M-PFS, after 3 years of follow-up).

For high-risk CINSARC patients, this is a multicenter randomized two-arm phase III trial, with a ratio 1:1:

* Arm A: standard management (3 cycles of neoadjuvant doxorubicin based chemotherapy + surgery +/- radiotherapy)
* Arm B: experimental arm (6 cycles of neoadjuvant doxorubicin based chemotherapy + surgery +/- radiotherapy)

For low-risk CINSARC patients, this a multicenter prospective cohort with treatment at the discretion of the investigator.

This is a multicenter trial with:

* An open randomized two-arm phase III trial for high-risk CINSARC patients assessing whether the addition of 3 additional neo-adjuvant cycles of chemotherapy (doxorubicin based chemotherapy) to standard management (3 cycles of neoadjuvant anthracycline based chemotherapy + surgery +/- radiotherapy) improves the outcome of patients
* a prospective cohort for low-risk CINSARC patients.

Benefit of Intensified Peri-operative Chemotherapy Within High-risk CINSARC Patients With Resectable Soft-tissue Sarcomas

Phase III Trial Investigating the Potential Benefit of Intensified Peri-operative Chemotherapy With in High-risk CINSARC Patients With Resectable Soft-tissue SARComas

Metastasis progression-free survival (M-PFS) defined as the time interval between the date of randomization and the date of death or distant progression.

Loco-regional relapse-free survival (LR-RFS) defined as the time interval between the randomization date and the date of death or loco-regional progression.

Progression-free survival (PFS) defined as the time interval between the randomization date and the date of death or progression (as per RECIST v1.1).

Overall survival (OS) defined as the time interval between the randomization date and the date of death.

Best overall response under treatment as per RECIST v1.1.

Histological response defined as the proportion of recognizable cells on the tumor sample.

Toxicity graded using the common toxicity criteria from the NCI v5.

Progression-free survival defined as the time interval between the randomization date and the date of death or progression (as per RECIST v1.1).

Metastasis progression-free survival defined as the time interval between the inclusion date and the date of death or distant progression.
