Oral mucositis remains a debilitating side effect for cancer patients undergoing intensive chemotherapy or radiation. Finding effective pain management strategies is crucial for maintaining quality of life and nutritional intake. A recent clinical study investigated the efficacy of Methylene Blue for oral mucositis pain compared to traditional supportive care mouthwashes. Researchers focused on providing a practical and affordable alternative for hospitalized patients suffering from this condition.
The open-label, non-randomized trial evaluated 43 patients who used either 0.05% Methylene Blue (MB) or a standard medication mouthwash. Patients performed the oral rinse every eight hours for three consecutive days. Both groups showed statistically significant reductions in pain scores. However, the MB group demonstrated a notable decrease in the pain numeric rating scale. Furthermore, this treatment offers a cost-effective option for many oncology departments in resource-limited settings. Consequently, clinicians are looking closer at this dye for its analgesic properties.
Beyond simple pain relief, the trial examined secondary outcomes like daily oral intake volume and opioid requirements. Patients using the Methylene Blue rinse reported better tolerance and management of their symptoms. Additionally, the linear mixed model analysis confirmed that the pain reduction was consistent across the treatment period. Moreover, the study suggests that MB may work through multiple mechanisms, including peripheral neurolysis and inhibition of nitric oxide. Ultimately, healthcare providers should consider these findings when selecting supportive care options for oral complications in cancer therapy.
The study utilized a 0.05% concentration of Methylene Blue mouthwash for the participants to ensure safety and efficacy.
In this clinical trial, patients performed the oral rinse every 8 hours for a duration of three days to achieve optimal pain reduction.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
