Summary
Electron beam radiation therapy offers a potential solution for recalcitrant conjunctival and corneal squamous cell carcinoma. This approach achieved local tumor control in 75% of patients who had failed prior treatments.
Area of Science:
- Ophthalmology
- Radiation Oncology
Background:
- Squamous cell carcinoma (SCC) of the conjunctiva and cornea can be challenging to treat, especially when resistant to standard therapies.
- Recalcitrant cases often require alternative treatment modalities to achieve local control and prevent metastasis.
Purpose of the Study:
- To evaluate the efficacy and safety of electron beam radiation therapy (EBRT) as a salvage treatment for refractory conjunctival and corneal SCC.
- To report preliminary outcomes, including local control rates and adverse effects, of EBRT in this patient cohort.
Main Methods:
- A retrospective case series involving eight patients with pathologically confirmed conjunctival/corneal SCC who had failed previous treatments.
- Patients received EBRT, and outcomes such as local control, recurrence, complications, and mortality were assessed.
- Kaplan-Meier method was used to calculate survival probability for local control and mortality.
Main Results:
- EBRT was administered to eight patients (6 male, 2 female; mean age 50 years) with advanced SCC (T2-T4N0M0).
- Local tumor control and regression were achieved in 6 patients (75%), with recurrence in 2 patients.
- Common side effects included eyelid erythema, edema, and transient eyelash loss; no metastatic spread or tumor-related deaths were observed.
Conclusions:
- Electron beam radiation therapy demonstrates potential as a viable salvage option for patients with recalcitrant conjunctival and corneal squamous cell carcinoma.
- This therapeutic approach may be considered for individuals who have not responded to conventional treatment modalities.
