I-II期黑色素瘤可能也需要进行辅助治疗

几十年来,皮肤黑色素瘤的发病率一直在稳步上升,从1950年代的1例/10万人增加到今天的30-50例/10万人,而且在初诊时肿瘤厚度达到1mm的薄黑色素瘤的概率也越来越高。这种增加主要是因为紫外线照射。

首个采用免疫检查点抑制剂辅助治疗II期黑色素瘤的随机试验的结果显示,肿瘤复发风险显著降低。该研究旨在评估两个独立的数据集,以进一步明确I-II期黑色素瘤患者的生存率。

德国的CMMR研究评估了2000年-2015年期间接受治疗的17544例I-II期原发性黑色素瘤患者。探索性队列纳入了6725位患者,验证队列纳入了10819位患者。主要终点是生存预后,与已报道的美国癌症联合委员会第8版(AJCCv8)I-II期患者的生存数据进行比较。


探索性队列(A)和验证性队列(B)的黑色素瘤特异性生存率

与AJCCv8队列相比,CMMR研究两个队列的IA期患者的10年黑色素瘤特异性生存率是:95.1%-95.6% vs 98%;CMMR研究队列和AJCCv8队列IB期患者的10年黑色素瘤特异性生存率为:89.7%-90.9% vs 94%;IIA期患者:80.7%-83.1% vs 88%;IIB期患者:72.0%-79.9% vs 82%;IIC期患者:57.6%-64.7% vs 75%。IA-IIA期患者的复发率大约是黑色素瘤特异性死亡率的两倍。


CMMR研究的黑色素瘤特异性死亡率和复发率

综上,在CMMR研究的两个队列中,I-II期黑色素瘤患者的黑色素瘤特异性生存率均逊色于已发表的AJCCv8队列结果。因此,这类患者或需要进行适当的辅助治疗。
