Our study suggests that the Nursing Activities Score measures the consumption of nursing time in the intensive care unit. These results should be validated in independent databases.

BACKGROUND Cutaneous melanomas are aggressive tumors with an unpredictable biologic behavior. It has been suggested that women who present with melanoma during pregnancy have a worse prognosis due to more aggressive behavior of the melanoma. The objective of the current study was to evaluate the long‐term effect of pregnancy on disease progression in women with Stage I–II melanoma. METHODS From 1965 to 2001, 46 pregnant women were treated for a Stage I–II melanoma at the University Medical Center Groningen. These patients were compared with an age‐matched and gender‐matched control group (nonpregnant) of 368 women with Stage I–II melanoma. The patients were staged according to the 2002 American Joint Committee on Cancer TNM classification system for melanoma. The 10‐year disease‐free survival (DFS) and 10‐year overall survival (OS) rates were calculated using logistic regression analysis. RESULTS The median age of patients in the pregnant group was 30 years (range, 18–46 years), and the median age of patients in the nonpregnant group was 36 years (range, 17–45 years). The median follow‐up was 109 months (range, 1–356 months). Pregnant patients presented more often with thicker melanomas (median, 2.0 mm vs. 1.7 mm; not statistically significant). No differences with regard to tumor location, histologic subtype, tumor ulceration, or vascular invasion were detected between the pregnant group and the nonpregnant group. There was no statistical difference in the 10‐year DFS and 10‐year OS rates between the two groups. The 10‐year DFS rates for patients in the pregnant and nonpregnant groups, respectively, were 88% versus 86% for patients with Stage I melanoma and 67% versus 73% for patients with Stage II melanoma. The 10‐year OS rates for patients in the pregnant and nonpregnant groups, respectively, were 94% versus 90% for patients with Stage I melanoma and 82% versus 81% for patients with Stage II melanoma. CONCLUSIONS Pregnancy does not appear to have an adverse, long‐term effect on survival in patients with clinically localized melanoma. Further studies should address whether pregnant patients present with thicker lesions and/or whether they have decreased DFS compared with nonpregnant women. The prognosis for women with melanoma during pregnancy, as it relates to survival, still is dependent on tumor thickness and ulceration. Cancer 2003;97:2248–53. © 2003 American Cancer Society.
