Summary
This summary is machine-generated.Observation is a safe approach for small choroidal melanocytic tumors (SCMTs), with a low melanoma transformation rate. Close monitoring allows timely intervention if tumors grow, ensuring good patient survival outcomes.
Area Of Science
- Ophthalmology
- Oncology
- Medical Imaging
Background
- Small choroidal melanocytic tumors (SCMTs) require careful management due to potential melanoma transformation.
- Long-term outcomes for SCMTs managed conservatively are not fully elucidated.
Purpose Of The Study
- To analyze the long-term evolution of SCMTs under observation.
- To determine the rate of transformation into melanoma.
- To assess patient survival rates.
Main Methods
- Retrospective single-cohort study of 243 patients with SCMTs (1-3 mm height, 5-10 mm base).
- Initial treatment was observation.
- Melanoma transformation defined by >1 mm growth in height/base within 1-3 months on imaging.
Main Results
- Mean follow-up was 7.9 years.
- Tumor growth observed in 27 patients; 5, 10, and 15-year growth probabilities were 10%, 14%, and 17%.
- Survival rates at 5 and 10 years were 99% and 97%, with only 3 melanoma metastasis deaths.
Conclusions
- Observation is a viable treatment for SCMTs, minimizing treatment side effects.
- Most SCMTs do not progress to melanoma.
- Prompt treatment upon detected transformation is crucial; metastatic risk is low.
