Malignant eyelid tumours in Taiwan.

Area of Science:

• Ophthalmology
• Oncology
• Dermatology

Background:

• Eyelid cancers represent a significant clinical challenge.
• Understanding the epidemiology and characteristics of eyelid malignancies is crucial for effective patient management.

Purpose of the Study:

• To delineate the clinical features of eyelid cancers in the Taiwanese population.
• To compare the prognoses of different types of eyelid malignancies.

Main Methods:

• Retrospective analysis of 127 histologically confirmed eyelid cancer cases from 1980-2000.
• Review of clinical data, including tumor location, type, treatment, and follow-up outcomes.
• Statistical comparison of recurrence, metastasis, and mortality rates between basal cell carcinoma and sebaceous gland carcinoma.

Main Results:

• Basal cell carcinoma (62.2%) was the most prevalent eyelid cancer, followed by sebaceous gland carcinoma (23.6%).
• Tumors occurred more frequently on the lower eyelid (37.0%) than the upper eyelid (33.9%).
• Five-year rates for recurrence, metastasis, and mortality were 15.2%, 11.7%, and 7.3%, respectively, with significantly higher rates for sebaceous gland carcinoma compared to basal cell carcinoma.

Conclusions:

• Basal cell carcinoma is the most common eyelid cancer in Taiwan, but sebaceous gland carcinoma also warrants attention due to its aggressive nature.
• Sebaceous gland carcinoma presents a poorer prognosis and higher mortality risk than basal cell carcinoma, demanding more aggressive therapeutic strategies.
• Long-term monitoring is essential for patients treated for malignant eyelid tumors to detect and manage recurrences or metastases effectively.
