1. Introduction
Cutaneous metastases occur in approximately 0.7–0.9% of all cancer
patients.1 Cutaneous metastasis can cause symptoms
such as exudates, bleeding, and pain, which remarkably reduce patient’s
quality of life. Radiation therapy is one of the effective treatment
methods for cutaneous metastasis.2,3 Recently, the
“Quad Shot” regimen, comprising 2 days of twice-daily fractionation
with a fraction size of 3.5–3.7 Gy (14.0–14.8 Gy per cycle) repeated
at 3–6-week intervals for a total of three cycles, has been
successfully adapted for palliative treatment of head and neck
cancer.4,5 However, to the best of our knowledge,
there is no reports of using the Quad Shot regimen for cutaneous
metastasis.
Herein, we report a case in which radiation therapy using the Quad Shot
regimen was effective in the treatment of cutaneous metastasis from
parotid gland cancer.
