Skin Cancer and Hyperthermia and Radiotherapy

Summary

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).

Eligibility

Inclusion Criteria:

* Personally signed and dated written informed consent
* Histologically confirmed invasive non-melanoma skin cancer (NMSC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of any differentiation
* ≥ T2 (TNM Classification 8th Edition)
* Tumor thickness up to 2cm (Maximum Depth invasion and/or exophytic growth, measured on pathology report or imaging)
* Local recurrence allowed, if primary treatment longer ago than 6 months (after primary treatment other than radiotherapy (RT))
* Age ≥ 65 years
* Eastern Cooperative Oncology Group (ECOG) performance status 0-2, with a life expectancy of more than 6 months
* Presentation at the Swiss Hyperthermia Network (SHN) tumor conference mandatory

Exclusion Criteria:

* Other histology than BCC or SCC
* T1 tumor and/or N+ (according to TNM classification 8th edition)
* Tumors after resection (R1 or R2 as well as adjuvant indication)
* Tumor invasion into critical areas
* Several lesions exceeding the capacity of one treatment/radiation field (multiple lesions within one treatment field are acceptable)
* Previous (one month) or concurrent Chemo- or Immunotherapy
* Patients with connective tissue disorders (e.g. Sclerodermia, Lupus erythematodes)
* Lesions inside or in proximity (within 3cm) previously irradiated area
* Medical immunosuppression
* wIRA-specific exclusion criteria

  * Tattoos in irradiated area
  * Increased photosensitivity (either due to simultaneous treatment with photosensitivity-enhancing medications or conditions such as porphyria)
