Summary
After a screening, which consists of biopsy, physical examination, initial diffusion-weighted magnetic resonance imaging (DWI-MRI) or body computed tomography (CT) scan, blood tests and case analysis on Multidisciplinary Team (MDT) meeting, a patient with radiation-induced or in-field recurrent sarcoma will receive the hypofractionated radiotherapy with deep hyperthermia (twice a week) within three weeks. The response analysis in CT or DWI-MRI and toxicity assessment will be performed after 6 weeks. In resectable tumors, a patient will be referred to surgery. In the case of unresectability, the patient will followed-up.
Description
Due to the rarity of radiation-induced (RIS) or previously irradiated recurrent (PIRS) sarcomas, no guidelines nor randomized prospective clinical trials on this topic exist. Thus the management of RIS and PIR is challenging. The only curable modality in non-metastatic RIS/PIRS is radical resection with wide negative margins. The role of secondary radiotherapy in locally advanced RIS/PIRS is unclear, mostly due to the concerns about possible severe side effects after re-irradiation.
The addition of deep hyperthermia to irradiation and in the prolonged gap between the end of moderately hypofractionated radiotherapy (with or without integrated boost) and surgery may allow obtaining the long-term local control with the maintenance of a good treatment tolerance Hyperthermia is a method of increasing the temperature in the tumor to damage cancer cells with minimum injury to the normal cells. It should be combined with another treatment modality (radio- or chemotherapy) rather than used alone. Its efficacy was proven in clinical trials. Treatment tolerance is usually very good.
