Melanoma case survival rates in South Australia by histological type, thickness and level of tumour at diagnosis.

Data from the South Australian Cancer Registry on malignant melanoma of the skin showed that case survival rates were higher for lentigo maligna melanomas and superficial spreading lesions than for nodular and other histological classifications. Lower case survival rates applied to the thicker melanomas and those at a more invasive level at diagnosis. After adjusting for differences in thickness and level in this study, no statistically significant differences were apparent between case survival rates for the nodular lesions and the lentigo maligna and superficial spreading melanomas.
