[UV-ray sensitivity of patients with malignant melanoma].

In 77 patients with malignant melanoma and 74 control subjects without skin tumors caused by sunlight, the minimal erythema dosage (MED) in the UV-C and UV-B areas, immediate pigment darkening (IPD), and minimal tanning dose (MTD) were determined according to skin type. Direct (MED-UV-B, MED-UV-C) and inverse (IPD, MTD) correlations were established according to skin type. These parameters showed no differences between patients with malignant melanoma and the control group.
