At present, Sanger sequencing is still the gold standard in clinical practice to detect mutation, and amplification refractory mutation system PCR (ARMS-PCR) has become widely used due to its higher sensitivity and less limitation compared with Sanger sequencing. Mutation-selected amplification specific system PCR (MASS-PCR) is a novel gene detection technique with high specificity and sensitivity. This study aimed to compare the accuracy and sensitivity of ARMS-PCR and MASS-PCR and purposed to make an alternative choice in gene mutation detection in lung cancer. Method: A total of 293 formalin-fixed paraffin-embedded (FFPE) tissues were collected from 293 patients with lung cancer from 2017 to 2018. The sample mutation statuses were evaluated by ARMS-PCR and MASS-PCR. Sanger sequencing was also conducted to confirm the results further. The consistency of ARMS-PCR and MASS-PCR were analyzed, and receiver operating characteristic (ROC) curve was drawn to assess the sensitivity and specificity of MASS-PCR. Results: The consistency rate between the MASS-PCR and Sanger sequencing (kappa value =0.929) was higher than that between the MASS-PCR and ARMS-PCR (kappa value =0.821). There were 20 samples had inconsistent results among the three assays. For these samples, 11 positive samples were verified by the MASS-PCR and Sanger sequencing. Besides, 3 negative samples in Sanger sequencing were detected to be positive in MASS-PCR and ARMS-PCR. The ROC area under the curve (AUC) of assay panels was 0.930 referring to ARMS-PCR, and 0.967 as Sanger sequencing was referred to. Conclusions: Our study demonstrated a higher accuracy and sensitivity of MASS-PCR than ARMS-PCR. Therefore, MASS-PCR could be used in clinical practice to detect gene mutations in lung cancer patients. UR - https://tcr.amegroups.org/article/view/33006
