UNASSIGNED: Multi-site, cross-sectional study design incorporating a descriptive survey and total body skin cancer screening, including artificial intelligence by a skin cancer doctor.
UNASSIGNED: A total of 260 participants with suspect MM lesions were biopsied, with 83 (31.9%) found to be melanomas. Of the true positive MMs only a small percentage of participants (21.7% specificity) correctly had concerns about the suspect lesion being a MM. These MMs were located primarily on the back (44.4%), shoulder (11.1%) and upper leg (11.1%). There was no significant difference in the size between those participants aware of a MM versus those who were not (P = 0.824, 24.6 vs 23.4 mm2). Significantly more males identified lesions of concern that were MMs as compared to females (P = 0.008, 61.1% vs 38.9%, respectively). With regard to true negatives males and females were similar (52.1% vs 47.9%, respectively). With regard to false negatives (n = 65), a greater percentage of males than females did not recognize the MM as a lesion of concern (66.2% vs 33.8%, respectively). Participants were more likely to correctly identify an invasive MM as opposed to an in situ MM (27.3% versus 21.3%).
UNASSIGNED: Only a small percentage of participants in this study were able to self-identify either in situ or invasive MM as a lesion of concern with a tendency to identify the more advanced, thicker MMs. Given that MM is associated with a high mortality and cost of treatment, particularly when invasive, the inability of lay persons to identify these cancerous lesions will likely lead to delayed treatment and a possible adverse outcome. We believe the current melanoma screening practices in Australian general practice should be revisited to improve patient outcomes with regard to MM. Additionally, prevention campaigns should include images and primary risk factors for MM.
■多站点,横断面研究设计,包括描述性调查和全身皮肤癌筛查,包括皮肤癌医生的人工智能。
■共260名疑似MM病变的参与者进行了活检,83(31.9%)被发现是黑色素瘤。在真正的阳性MM中,只有一小部分参与者(21.7%的特异性)正确地担心可疑病变是MM。这些MMs主要位于背面(44.4%),肩膀(11.1%)和大腿(11.1%)。意识到MM的参与者与未意识到MM的参与者之间的大小没有显着差异(P=0.824,24.6vs23.4mm2)。与女性相比,男性明显更多的被关注病变(P=0.008,61.1%vs38.9%,分别)。关于真阴性,男性和女性相似(52.1%vs47.9%,分别)。关于假阴性(n=65),与女性相比,男性比例更高(66.2%vs33.8%,分别)。与原位MM相比,参与者更有可能正确识别侵入性MM(27.3%对21.3%)。
本研究中只有一小部分参与者能够自我识别原位或侵袭性MM为关注的病变,并倾向于识别更晚期的病变,考虑到MM与高死亡率和治疗成本相关,特别是在侵入性的时候,非专业人员无法识别这些癌性病变可能会导致治疗延迟和可能的不良结果。我们认为,应该重新审视澳大利亚全科医生目前的黑色素瘤筛查做法,以改善患者在MM方面的预后。此外,预防活动应包括MM的图像和主要危险因素。
