The present prospective study evaluated sun exposure and sun protection behaviours in patients diagnosed with a precancerous or cancerous skin lesion. Following signed informed consent, patients were given a questionnaire regarding sun protection and sun exposure behaviour. There were 50 patients (27 men, 23 women) with a mean age of 59 years. Following diagnosis of a cancerous or precancerous lesion, there was a significant increase (P<0.001) in sunscreen use, use of sun protection factor greater than 30, wearing a hat and avoidance of sun between 10:00 and 14:00. There were significantly more women who used sunscreen (P=0.04) and limited daily activities (P=0.03). There were significantly more patients with nonmelanoma lesions who wore hats (P<0.04) and more patients with melanoma who limited daily activities (P<0.04). While many patients in the present study did alter their sun protection and exposure behaviour, there were many patients who continued in risk-taking sun behaviour. Therefore, patients with precancerous or cancerous skin lesions who are not compliant with sun protective behaviour may benefit from more comprehensive patient education to encourage better sun protection behaviour.
本前瞻性研究评估了被诊断患有癌前或癌性皮肤病变的患者的日晒情况和防晒行为。在签署知情同意书后,向患者发放了一份关于防晒和日晒行为的问卷。共有50名患者(27名男性,23名女性),平均年龄为59岁。在被诊断患有癌性或癌前病变后,使用防晒霜、使用防晒系数大于30的产品、戴帽子以及避免在10:00至14:00之间晒太阳的情况显著增加(P<0.001)。使用防晒霜的女性显著更多(P=0.04),且限制日常活动的女性也显著更多(P=0.03)。患有非黑色素瘤病变的患者戴帽子的显著更多(P<0.04),患有黑色素瘤的患者限制日常活动的显著更多(P<0.04)。虽然本研究中的许多患者确实改变了他们的防晒和日晒行为,但仍有许多患者继续采取有风险的日晒行为。因此,不符合防晒行为的癌前或癌性皮肤病变患者可能会从更全面的患者教育中受益,以鼓励更好的防晒行为。
