Intensive pediatric chemotherapy regimen (PNET HR+5) in adult high-risk medulloblastoma and pineoblastoma patients.

Background: High-risk medulloblastoma (HRMB) is rare in adults. The 5-year overall survival rate is less than 60%. We present here a retrospective analysis of adults treated with an intensive pediatric chemo-radiotherapy regimen PNET HR + 5: NCT00936156.

Local relapse patterns after preoperative radiotherapy of limb and trunk wall soft tissue sarcomas: Prognostic role of imaging and pathologic response factors.

Purpose: To retrospectively identify clinical, pathologic, or imaging factors predictive of local relapse (LR) after preoperative radiotherapy (RT) for soft tissue sarcomas (STS).

Methods And Materials: This is a retrospective multicenter study of patients who underwent preoperative RT and surgery for limb or trunk wall STS between 2007 and 2018 in French Sarcoma Group centers and were enrolled in the "Conticabase". Patterns of LR were investigated taking into account the multimodal response after preoperative RT.

Management of oligometastatic/metastatic sarcomas and place of local treatments with focus on modern radiotherapy approaches.

Soft tissue sarcomas are a rare and heterogeneous disease. For localized disease, treatment is based on surgery and radiotherapy with or without chemotherapy depending on risk factors. Upfront metastases are present in 7 to 20% of cases, and are localized to the lungs in most of cases.

Randomized phase III trial of metabolic imaging-guided dose escalation of radio-chemotherapy in patients with newly diagnosed glioblastoma (SPECTRO GLIO trial).

Background: Glioblastoma (GBM) systematically recurs after a standard 60 Gy radio-chemotherapy regimen. Since magnetic resonance spectroscopic imaging (MRSI) has been shown to predict the site of relapse, we analyzed the effect of MRSI-guided dose escalation on overall survival (OS) of patients with newly diagnosed GBM.

Methods: In this multicentric prospective phase III trial, patients who had undergone biopsy or surgery for a GBM were randomly assigned to a standard dose (SD) of 60 Gy or a high dose (HD) of 60 Gy with an additional simultaneous integrated boost totaling 72 Gy to MRSI metabolic abnormalities, the tumor bed and residual contrast enhancements.

Treatment of radiation-associated angiosarcoma.

Purpose Of Review: Radiation-associated angiosarcoma is a cutaneous aggressive tumor that is very rare and it represents a specific entity poorly studied in literature. It requires new therapeutic opportunity.

Recent Findings: The complete surgical resection with negative margins is the mainstay treatment of localized treatment, even though it is difficult to reach in case of diffuse cutaneous infiltration.
