Standard fractionation has long been considered a standard approach to reduce long-term toxicity.5 A meta-analysis of patients with SCC and BCC showed that hypofractionation has favourable cosmesis and recommended the use of regimens with BED3 of ~100 Gy, such as 50 Gy in 15 fractions, 36.75 Gy in 7 fractions or 35 Gy in 5 fractions, as they...
Skin cancer. Squamous cell carcinoma and basal cell carcinoma. Background. Surgery and radiotherapy are both highly efective curative treatment modalities for squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). The choice of treatment modality is determined by factors including age, tumour size and functional/cosmetic outcomes.
This guideline provides recommendations on the use of radiation therapy (RT) to treat patients diagnosed with the most common types of skin cancers. It details when radiation treatments are appropriate as stand-alone therapy or following surgery for basal and cutaneous squamous cell carcinomas (BCC, cSCC), and it suggests dosing and ...
This guideline reviews the evidence for the use of definitive and postoperative radiation therapy (RT) in patients with basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC).
Use of pre-treatment ultrasound and ongoing imaging to adjust radiation energy and dose, combined with a fractionation treatment schedule of 20 or more treatment fractions, has the potential to be associated with improved local tumor control in NMSC lesions compared to SRT without ultrasound imaging.
When radiation is used as the main treatment for a skin tumor (or after surgery), it’s often given 5 days a week for several weeks. Another option might be to give higher doses of radiation over fewer treatments (known as hypofractionation ).
11 Ιαν 2023 · Radiation oncologists classically utilize high-energy megavoltage photons in the range of 6–25 mV through the use of a linear accelerator (LINAC) to manage internal malignancy. The LINAC uses microwave technology to accelerate electrons to collide with a heavy metal and produce high-energy X-rays.
