RET (Ret Proto-Oncogene)

Herein, we report the first documented case of phenotypic conversion to SCLC in a patient with advanced pulmonary sarcomatoid carcinoma (PSC) who received pemetrexed, carboplatin, and camrelizumab only, with no targeted agents administered. TP53 and RET mutations may be implicated in this phenotypic transition. This case provides new insights into the biological mechanism underlying the evolution of PSC to SCLC.

Among the tested compounds, entrectinib exhibited consistently strong binding affinities across all variants (-9.7 to -10.7 kcal/mol), whereas reduced binding affinities were observed for several inhibitors against E734K, A756D, and R897G variants...Clinical databases reported that p.Met918Thr (pathogenic) and p.Arg897Gln (risk factor) emerged as significant variants linked to MEN2-related cancers and Hirschsprung disease. As a conclusion, this integrative in silico study identifies deleterious RET nsSNPs with potential structural, functional, and therapeutic significance providing mechanisms for precision oncology and future clinical investigation.

These observed frequencies should be interpreted as case-level implementation signals surfaced through routine CGP rather than assay superiority evidence, biological prevalence estimates, or treatment-benefit data. This nationwide, platform-aware benchmark supports practical interpretation of tumor-agnostic eligibility signals in routine CGP practice in Japan.

Advanced RAI-R TC candidates for systemic therapy often harbor gene alterations. An adequate result was less frequently achieved in cases of RNA-based NGS than in DNA-based NGS, especially if the interval between tissue collection and molecular analysis was longer; nevertheless, the limited cohort size precludes definitive conclusions.

Rare actionable genomic alterations are recurrently identified in NGS-assessed NSCLC cohorts. These findings support the clinical value of broad genomic profiling, provide realistic expectations for diagnostic yield in routine practice, and may inform precision oncology implementation, molecular-testing pathways, and resource allocation.

RET fusion-positive PTC is associated with aggressive clinicopathological behavior and poor prognosis. This study highlights the importance of RET fusion testing in PTC for more accurate risk stratification and personalized therapeutic approaches, particularly for high-risk patients.

TSO500 demonstrates high concordance with G360 for detecting actionable alterations and robust fusion identification. Its ability to detect additional variants and resistance mutations not found in tissue highlights its potential value in guiding personalized treatment decisions for NSCLC patients.

We present the case of a 60-year-old non-smoking woman previously treated for luminal B human epidermal growth factor receptor 2 (HER2)-positive invasive breast carcinoma with surgery, AC60 chemotherapy, trastuzumab, breast radiotherapy, and hormone therapy at the Mohammed VI Oncology Center in Casablanca, Morocco. The patient received neoadjuvant vinorelbine-cisplatin chemotherapy followed by volumetric modulated arc therapy (VMAT) thoracic radiotherapy at 66 Gy, achieving clinical and radiological stabilization. This case highlights the occurrence of a second driver-negative primary lung adenocarcinoma in a non-smoker and underscores the importance of integrated histopathological, immunohisto chemical, and targeted molecular evaluation in distinguishing primary tumors from metastases, as well as the potential role of post-therapeutic carcinogenesis.

For cases lacking these specific markers, VEGFR-targeted multikinase inhibitors (e.g., lenvatinib) remains the standard of care for RAIR-DTC...The therapeutic paradigm in thyroid cancer is shifting from non-selective multikinase inhibition toward molecularly matched, combination-based, and adaptively sequenced strategies. Early and comprehensive genomic profiling-including fusion detection-is essential to optimize treatment selection, address resistance, and expand precision therapy options across disease subtypes.

The consistent cost-effectiveness results between pre-submission and post-submission phases support the potential of SEE to complement health technology assessment (HTA) and potentially inform earlier (conditional) reimbursement decisions for this single case study. However, future research should focus on refining SEE protocols for continued methodological development and validation to improve generalizability and applicability.
