RET (Ret Proto-Oncogene)

The Bethesda system provides high diagnostic accuracy for definitive cytological categories in pediatric thyroid nodules. Even indeterminate categories carry elevated malignancy risk, supporting careful surgical consideration and the value of BRAF V600E testing for preoperative risk stratification.

This article reviews genotype-phenotype correlations, clinical manifestations, and current therapeutic strategies, including the use of selective tyrosine kinase inhibitors. In addition, we propose an algorithm for the treatment of advanced medullary thyroid carcinoma and metastatic pheochromocytoma.

This nationwide analysis benchmarks how RET-positive findings are surfaced to clinicians across heterogeneous routine CGP implementations in Japan. The data support platform-aware interpretation of RET results in practice, but should not be construed as biologic prevalence estimates or comparative assay performance.

Depending on the Bethesda category, the positive predictive value for malignancy of the seven-gene panel ranged between 18.18% (Bethesda III) and 91.07% (Bethesda V), while the negative predictive value ranged between 93.92% (Bethesda III) and 24.14% (Bethesda V). In conclusion, molecular testing with the seven-gene panel can improve ROM estimation in cytopathologically indeterminate thyroid nodules, but its clinical utility depends on the detected gene alteration.

RET fusions and genetic alteration combination are independent prognostic markers for tumor recurrence of PTC, integrating tumors' genetic status into the 2025 ATA RSS system improves the accuracy of risk stratification for PTC.

Systematic genetic screening and counselling are essential for the early diagnosis and appropriate management of MEN2A, particularly in sporadic cases. Broader implementation of molecular testing and genetic counselling in Algeria is recommended to improve patient outcomes and prevent transmission to future generations.

Resistance to RET inhibitors can be acquired through RET copy-number gain and secondary mutations as well as NF1 loss-mediated MAPK pathway activation. This mechanism of resistance can be overcome with dual inhibition of RET and downstream RAS/MAPK signaling, demonstrating clinical potential in RET-mutant MTC.
