High-Resolution Melting Analysis for accurate detection of BRAF mutations: a systematic review and meta-analysis
نویسندگان
چکیده
The high-resolution melting curve analysis (HRMA) might be a good alternative method for rapid detection of BRAF mutations. However, the accuracy of HRMA in detection of BRAF mutations has not been systematically evaluated. We performed a systematic review and meta-analysis involving 1324 samples from 14 separate studies. The overall sensitivity of HRMA was 0.99 (95% confidence interval (CI) = 0.75-0.82), and the overall specificity was very high at 0.99 (95% CI = 0.94-0.98). The values for the pooled positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 68.01 (95% CI = 25.33-182.64), 0.06 (95% CI = 0.03-0.11), and 1263.76 (95% CI = 393.91-4064.39), respectively. The summary receiver operating characteristic curve for the same data shows an area of 1.00 and a Q* value of 0.97. The high sensitivity and specificity, simplicity, low cost, less labor or time and rapid turnaround make HRMA a good alternative method for rapid detection of BRAF mutations in the clinical practice.

KRAS and BRAF mutations in Iranian colorectal cancer patients: A systematic review and meta-analysis
Background: Mutations in the EGFR signaling pathway play an important role in the development of colorectal cancer (CRC). Mutations in these genes, like KRAS and BRAF, affect the treatment strategies and associated with poor prognosis and relative resistance to anti-EGFR therapies. Our aim was to conduct a systematic and meta-analysis on all studies that have been conducted on the prevalence of...

Beta-thalassemia is one of the most common autosomal recessive disorders in the world population resulting from over 200 different mutations of HBB gene. Beta-thalassemias are caused by point mutations or, more rarely, deletions in the HBB gene leading to reduced (beta+) or absent (beta0) synthesis of the beta chains of hemoglobin (Hb). High-resolution melting of polymerase chain reaction (PCR)...
متن کاملA multisite blinded study for the detection of BRAF mutations in formalin-fixed, paraffin-embedded malignant melanoma
Melanoma patients with BRAF mutations respond to treatment with vemurafenib, thus creating a need for accurate testing of BRAF mutation status. We carried out a blinded study to evaluate various BRAF mutation testing methodologies in the clinical setting. Formalin-fixed, paraffin-embedded melanoma samples were macrodissected before screening for mutations using Sanger sequencing, single-strand ...

Background: Colorectal cancer (CRC) is the third most common cancer worldwide. microsatellite instability (MSI) is a molecular marker of a deficient mismatch repair system and happens in almost 15% of CRCs. Because of a wide frequency of MSI+ CRC in Iran compared to other parts of the world, the importance of screening for this type of cancer is highlighted. Methods: The most common MSI detecti...
