Effectiveness of 0.9% Normal Saline Soaking in Managing Acute Radiation Dermatitis

The goal of this clinical trial is to learn if normal saline soaks can reduce the severity of acute radiation dermatitis in patients with sarcomas or head and neck cancer receiving radiotherapy. It will also learn if saline soaks can improve wound healing and reduce treatment interruptions caused by skin toxicity. The main questions it aims to answer are:

1. Does the application of normal saline soaks reduce the severity of acute radiation dermatitis according to CTCAE Version 5.0? 2. Does the use of normal saline soaks improve wound healing time and reduce the frequency and duration of radiotherapy interruptions? Researchers will compare standard care plus saline soaks (intervention group) to standard care alone (control group) to see if saline soaks reduce skin reaction severity and improve clinical outcomes.

Participants will:

1. Be randomly assigned to receive either standard care alone or standard care with daily saline soaks 2. Apply saline-soaked gauze to the affected radiation area for 5-10 minutes once daily (intervention group only) 3. Attend weekly clinic visits for skin assessment during radiotherapy 4. Be assessed for skin reaction severity, wound healing, and treatment interruptions at baseline, after 4 weeks, and 2 weeks after completing treatment
