The Scottish Ocular Oncology Service (SOOS) manages all patients with uveal melanoma (UM) in Scotland. Our aim was to determine the long-term all-cause and cause-specific survival of patients with UM, irrespective of treatment modality.
A retrospective single-centre cohort study including all patients diagnosed with UM by the SOOS between 1/1/1998 and 31/12/2002. Data from the SOOS database were correlated with death records held by National Records of Scotland, which provided date, and all listed causes, of death for all deceased patients.
Two hundred and eighteen patients were newly diagnosed with UM between 1/1/1998 and 31/12/2002. One hundred and fifteen (52.8%) were female. The mean (median) age at diagnosis was 63(65) years (range: 16–89). Of 179 choroidal melanomas, melanoma-specific survival was 92.3%, 87.4% and 83.8% at 5, 10 and 15 years, respectively. Cancer-specific survival was 85.8%, 71.8% and 62.3%. All-cause survival was 81.6% (146/179), 62.0% (111/179) and 46.7% (computed, fraction inexpressible). Of 26 ciliary body melanomas, melanoma-specific survival was 87.2%, 81.3% and 81.3% at 5, 10 and 15 years. Cancer-specific survival was 62.9%, 40.6% and 40.6%. All-cause survival was 61.5% (16/26), 38.5% (10/26) and 26.9% (7/26). Of 13 iris melanomas, at all three timepoints (5/10/15 years), melanoma-specific survival was 100%, cancer-specific survival was 92.3%, and all-cause survival was 76.9% (10/13).
Correlation of SOOS and national records survival data confirms 15-year melanoma-specific survival of 83.8%, 81.3% and 100% for choroidal, ciliary body and iris melanomas, respectively. We can now provide accurate survival data to our patients in Scotland.
