SUMMARY
During the 25 year period of 1955 to 1979, 29 cases
of malignant melanoma of the choroid andciliary
body and 4 cases of melanoma of the iris were
diagnosed in Iceland. 78,6 % of all eye cancers and
0.29 % of all malignant neoplasms recorded in the
country were uveal melanomas. Excluding the iris
melanomas, the mean annual incidence rate per
100000, adjusted to standardized »Icelandic« popu-
lation, was 0.7 in males and 0.5 in females. No
change in the incidence rate was noted in five five
year periods, 1955-1979. There was no significant
difference in incidence rates between urban and
rural regions.
In 31. of December 1982 19 patients with melano-
ma of the choroid and ciliary body were dead and in
9 cases the cause of death was melanoma meatasta-
sis. All deaths in metastasis occurred within five
years from enucleation. In no case was metastasis
found before enucleation. Life table analysis was
used in computing surviva! rates but no account
could be taken of age distribution. Five year survival
rates for all patients was 51 %, 64 % in males and
30 % females. The difference of survival in relation
to length of history was not significant.
