Detaillierte Beschreibung
This study is a prospective, randomized, double-blind, placebo-controlled clinical trial evaluating spirulina as an adjunctive intervention for radiation-induced oral mucositis in patients receiving radiotherapy for head and neck cancer.
Radiation-induced oral mucositis is a common and clinically significant adverse effect of radiotherapy. It may cause oral pain, difficulty eating and swallowing, nutritional deterioration, reduced quality of life, and interruption of anticancer treatment. Current management is mainly supportive, and additional safe and effective interventions are needed.
Eligible participants will be randomized to receive either spirulina tablets or matching placebo in addition to standard oral care during radiotherapy. The study will compare the effects of spirulina and placebo on the severity, incidence, and duration of oral mucositis. Oral pain, nutritional status, quality of life, treatment compliance, radiotherapy interruption, and adverse events will also be evaluated.
The purpose of this trial is to determine whether spirulina supplementation can reduce the burden of radiation-induced oral mucositis and improve supportive care for patients undergoing radiotherapy. The safety of spirulina will be monitored throughout the study.

Incidence and Clinical Characteristics of Oral Mucosal Ulcers
Zeitfenster: From Day 0 (before intervention) through Day 14, assessed daily.
|
The incidence and clinical characteristics of oral mucosal ulcers were assessed by standardized oral examinations.
The number, location, maximum diameter, estimated ulcer area, erythema, pseudomembrane or exudate, and clinical severity of ulcers were recorded throughout the study.
|
From Day 0 (before intervention) through Day 14, assessed daily.
|
|
Oral Pain Intensity (Visual Analog Scale, VAS)
Zeitfenster: Day 0 (before intervention), Day 7, and Day 14.
|
Oral pain intensity was assessed using a 10-cm Visual Analog Scale (VAS), with scores ranging from 0 (no pain) to 10 (worst imaginable pain).
Higher scores indicate greater pain severity.
|
Day 0 (before intervention), Day 7, and Day 14.
|
|
Oral Microbiota Composition
Zeitfenster: Day 0 (before intervention), Day 7, and Day 14.
|
Oral microbiota samples were collected for metagenomic sequencing to evaluate changes in microbial composition, microbial diversity, and relative abundance following the intervention.
|
Day 0 (before intervention), Day 7, and Day 14.
|
|
Salivary Biomarkers
Zeitfenster: Day 0 (before intervention), Day 7, and Day 14.
|
Unstimulated saliva samples were collected to measure inflammatory and oxidative stress biomarkers, including IL-6, TNF-α, MDA, and SOD, to evaluate the biological effects of the intervention.
|
Day 0 (before intervention), Day 7, and Day 14.
