RESUMEN
PURPOSE: To describe the epidemiology, incidence, mortality and survival of ocular cancer in Cali between 1962 and 2019. METHODS: Ecological population-based study analyzing data of incidence, mortality, and 5-years survival of malignant ocular tumors from the Populational Cancer Registry of Cali between 1962 and 2019. RESULTS: Between 1962 and 2019, 586 ocular tumors were found, 50.5% occurred in females, the mean age at diagnosis was 45 years (standard deviation = 25), 70.3% of ocular malignancies occurred in >14 years. The average annual incidence rate was 7.8 per million for male and 6.9 per million for females. Retinoblastoma (21%), squamous cell carcinoma (20%), melanoma (16%) and lymphoma (8%) were the most common neoplasm. In those <15 years, the most frequent malignant tumors were retinoblastomas (85.7%), followed by non-specified malignant neoplasm (NOS, 7.9%), and rhabdomyosarcoma (3.6%). In those >14 years, there were NOS (30%), followed by squamous cell carcinomas (28%), melanomas (23%), and lymphomas (9.7%). Conjunctiva (38.2%), retina (21%) and orbit (10%) constituted the majority of anatomical sites of ocular tumors. The survival rate was about 83.2% and mortality did not show a decreasing trend over time (p > .05). CONCLUSIONS: The incidence of ocular cancer in Cali has a slightly increasing trend, with stable behavior in the last decades. Squamous cell carcinoma, retinoblastoma, melanoma and lymphoma are the most frequent ocular cancers, with being retinoblastoma more frequent than melanoma. In general, ocular cancer had good survival rates in Cali.
RESUMEN
Purpose: Intratumoral bacteria and their potential application to cancer immunotherapy have been a topic of interest in recent studies. To our knowledge, bacteria in uveal melanoma have not been previously reported. Observations: We describe a patient with a large choroidal melanoma, measuring 18 × 16 mm in basal dimension and 15 mm in ultrasonographic thickness, managed by plaque brachytherapy. At the time of plaque removal, a prophylactic scleral patch graft was placed to protect from anticipated scleral necrosis. Progressive ocular ischemia led to a blind and painful eye. The enucleated eye demonstrated an extensively necrotic and heavily pigmented mushroom-shaped regressed cilichoroidal mass deep to the scleral patch graft. Numerous Gram-positive cocci were noted within the regressed uveal melanoma and the adjacent sclera. Conclusions and Importance: This case highlights the fact that regressed uveal melanomas can contain intra-tumoral bacteria.
