遺傳性癌症基因檢測可評估PARP抑制劑治療的可行性
針對下列癌別能顯著延長疾病無惡化存活期及死亡率
轉移性乳癌
卵巢癌
胰臟癌
HER2- 轉移性乳癌且具有 germline BRCA突變患者 46%有效控制疾病進展及死亡率1
卵巢癌且具有 germline BRCA突變患者 70%有效控制疾病進展及死亡率2
胰臟癌且具有 germline BRCA突變患者 47%有效控制疾病進展及死亡率3
(germline testing)
NCCN Guidelines建議上述患者皆應接受遺傳性癌症基因檢測作為輔助性診斷檢查4-6
(tumor testing)
(germline testing)
-
腫瘤型基因檢測與遺傳性癌症基因檢測分析不同的生物標記
-
每一項腫瘤型基因檢測的定序覆蓋深度、變異分類方式、大片段重組分析的偵測率都有所不同
-
SOLO-1臨床試驗的結果顯示: 5%已知的germline BRCA突變,是腫瘤型基因檢測找不到的2 這差異足以影響患者的治療決策!
患者若帶有遺傳性的變異基因有很高的機率發展第二種癌症7-9
遺傳性乳癌及卵巢癌症候群之相關基因突變患者
10年內罹患乳癌
70歲後罹患乳癌
乳癌患者10年後罹患卵巢癌
遺傳性非瘜肉大腸直腸癌綜合症相關基因突變患者
10年內發展第二種癌症
15年內發展第二種癌症
(包含:卵巢癌、大腸癌、子宮癌、胰臟癌)
其家屬若也帶有相同變異基因,罹癌風險將高於一般族群7,10-15
乳癌
卵巢癌
大腸直腸癌
子宮癌
黑色素瘤
胰臟癌
胃癌
攝護腺癌
