简要总结
The SAHARA trial assesses wether combining ultrahypofractionated accelerated radiotherapy (RT) with hyperthermia is as effective as standard hypofractionated high-dose radiation in treating non-melanoma skin cancer (NMSC).
详细描述
The SAHARA Trial is investigating if adding hyperthermia to radiotherapy (RT) can enhance treatment outcomes by making cancer cells more sensitive to radiation, thus requiring lower doses and potentially reducing side effects. The trial compares high-dose RT alone with de-escalated RT plus hyperthermia. The aim is to demonstrate that the combination is non-inferior to standard RT in treating non-melanoma skin cancer (NMSC). The trial is designed for elderly people of 65 years or older.

结局指标
主要结局
Local control
时间窗: Within two years post-treatment initiation.
The primary outcome is local control, defined as the absence of of recurrence or need for subsequent intervention.
次要结局
- Analysis(Immediately (within 24 hours post-treatment), at six weeks post-treatment and at three months post-treatment.)
- Quality of life assessment(at three months, 6months, one year and two years post-treatment)
- Late toxicities(at 6months, one year and two years post-treatment)
