To determine how results from a prognostic 40-gene expression profiling (40-GEP) test would impact clinician management decisions and how their choices would align with a National Comprehensive Cancer Network (NCCN) compliant, risk-directed management plan for high-risk cutaneous squamous cell carcinoma (cSCC). Clinicians attending a national dermatology conference were presented with 40-GEP test validation data. They were asked to rate clinicopathological features and molecular test results to assess their opinion of how concerning each is to cSCC prognosis. When presented with vignettes describing patients with NCCN-defined high-risk features, clinicians were asked to select a treatment plan using pre-test (no 40-GEP results), then, post-test (40-GEP Class 1, 2A, or 2B results) methodology along with corresponding metastasis rates for each test group. Risk factors deemed of highest concern for metastatic outcomes were a Class 2B 40-GEP result, perineural invasion, immunosuppression, invasion beyond subcutaneous fat, and tumor diameter >1 cm on the scalp. When presented with a 40-GEP result that indicated reduced risk of metastasis (Class 1), clinicians altered their treatment management plan accordingly. Specifically, there was significant reduction in the recommendations for sentinel lymph node biopsy, adjuvant radiation or chemotherapy, follow-up time, and nodal imaging. By comparison, when a 40-GEP result indicated an increased risk of metastasis (Class 2B), significant risk-appropriate increases in management intensity was observed for the aforementioned clinical decisions. Integration of 40-GEP results impacted management decisions in a significant and risk-appropriate manner for high-risk cSCC patient scenarios, while remaining aligned with national guidelines for patient management.
为了确定预后 40 基因表达谱(40-GEP)检测的结果将如何影响临床医生的管理决策,以及他们的选择将如何与国家综合癌症网络(NCCN)符合风险导向的高危皮肤鳞状细胞癌(cSCC)管理计划保持一致。邀请参加全国皮肤科会议的临床医生参加了 40-GEP 测试验证数据。要求他们对临床病理特征和分子测试结果进行评分,以评估他们对每种特征对 cSCC 预后的关注程度。当提供描述具有 NCCN 定义的高危特征的患者的病例时,临床医生被要求使用预测试(无 40-GEP 结果),然后使用后测试(40-GEP 类别 1、2A 或 2B 结果)以及每个测试组的相应转移率选择治疗计划。被认为对转移结果最关注的危险因素是 2B 类 40-GEP 结果、神经周围侵犯、免疫抑制、侵犯皮下脂肪以外和头皮上肿瘤直径>1cm。当出现提示转移风险降低(类别 1)的 40-GEP 结果时,临床医生会相应地改变其治疗管理计划。具体而言,建议进行前哨淋巴结活检、辅助放疗或化疗、随访时间和淋巴结成像的显著减少。相比之下,当 40-GEP 结果表明转移风险增加(类别 2B)时,上述临床决策的管理强度显著增加。40-GEP 结果的整合以显著且风险适当的方式影响了高危 cSCC 患者情况下的管理决策,同时仍然符合患者管理的国家指南。
