Total Skin Treatment with Helical Arc Radiotherapy

Area of Science:

• Radiation Oncology
• Dermatology
• Hematology

Background:

• Widespread cutaneous lymphomas (e.g., mycosis fungoides, leukemia cutis) and chronic myeloproliferative diseases require effective treatment.
• Total skin irradiation (TSI) is an established modality for controlling these skin-predominant conditions.
• Achieving homogeneous skin irradiation is challenging due to the body's natural shape and skin folds.

Purpose of the Study:

• To review the evolution of total skin irradiation techniques.
• To specifically examine helical tomotherapy for TSI and its advantages.
• To compare different TSI methods, discuss adverse effects, and suggest future clinical care and dosimetry.

Main Methods:

• Literature review focusing on total skin irradiation techniques.
• Specific review of helical tomotherapy for total skin irradiation.
• Comparison of various treatment modalities, their benefits, and drawbacks.

Main Results:

• Total skin irradiation is efficient for disease control in specific hematologic malignancies affecting the skin.
• Helical tomotherapy presents an advanced method for achieving homogeneous skin irradiation.
• Comparison highlights differences in techniques, advantages, and potential adverse effects.

Conclusions:

• Total skin irradiation, particularly with advancements like helical tomotherapy, remains a crucial treatment for widespread cutaneous malignancies.
• Understanding technique evolution and comparative advantages is vital for optimal patient care.
• Further research into dose regimens and clinical management can enhance future TSI outcomes.
