ALK (Anaplastic lymphoma kinase)

Our study provides an example of implementation of molecular profiling in an academic pre-screening program. Further analysis will investigate treatment matching rates, drug access schemes, and their impact on treatment efficacy and survival.

4 pts received TT at recurrence, within clinical trials: one with grade 3 meningioma and ALK rearrangement treated with alectinib, one with PTCH1 mutant medulloblastoma treated with vismodegib, and two with high TMB treated with nivolumab/ipilumumab. The incidence of targettable molecular alterations in adult CNS tumor patients was lower than in GBM. Nevertheless, in a few selected cases TT have the potential to increase treatment options at recurrence and improve outcomes.

This case underscores the importance of early biopsy and molecular testing when standard treatments fail. Early recognition and routine examinations, including lymph node assessments and skin biopsies, are critical for improving patient outcomes, as timely diagnosis leads to more effective treatment options and potential remission.

We demonstrated that emetine exhibited effectiveness in inhibiting the growth of ALKi-resistant cells, and further interpreted its impact on the resistant signatures through drug-induced RNA-sequencing data. Our transcriptome-guided systematic approach paves the way for efficient drug discovery to overcome acquired resistance to cancer therapy.

Lorlatinib induced a complex dyslipidemia in our patient with elevations of both LDL-C and HDL-C. The underlying mechanism of lorlatinib-induced hyperlipidemia remains unknown and is unlikely to be secondary to nephrotic syndrome in many patients.

For ECOG PS 0-1 and PD-L1 <50% patients, median rwOS was 14.3 (95% CI: 10.1-NR) and 11.2 (95% CI: 9.1-21.3) months for PDC and PBC, respectively. Our real-world data support the benefit of single-agent PD-1 inhibitor monotherapy for patients with PD-L1 high expression or PD-1 inhibitor combination for all patients diagnosed with mNSCLC with no known EGFR/ALK/ROS1 aberrations, initiating 1L treatment.

Despite the rarity of NTRK fusions in pancreatic cancer, larotrectinib and entrectinib have exhibited effectiveness in NTRK fusion-positive pancreatic cancers. Additionally, repotrectinib, a next-generation NTRK inhibitor, has shown promising activity in NTRK positive pancreatic cancer patients who have developed acquired resistance to previous NTRK inhibitors. Immune checkpoint inhibitors, such as pembrolizumab and dostarlimab, have proven to be effective in dMMR/MSI-H pancreatic cancers...It is crucial to continue implementing comprehensive screening strategies that encompass the ability to detect all these tumor-agnostic biomarkers. This will be essential in identifying pancreatic cancer patients who may benefit from these therapies.

This real-world data confirms the efficacy of Lorlatinib in the second line and beyond with adverse effects matching that of registration studies.

This is the first report of multiple ALK-positive IMTs in both lungs, highlighting the need for definitive diagnosis and treatment of IMTs based on surgical resection. Although caution is required in patients with lymph node metastases or distant metastases, careful follow-up is acceptable unless there is a tendency for nodules to increase in size on imaging.

The combination of Panobinostat with Doxorubicin or Etoposide, both of which are used as standard of care in upfront treatment, leads to a synergistic effect in EWS cells. Overall, our data indicate that HDAC2 is overexpressed in many EWS tumor samples and HDAC inhibition is effective in targeting EWS cells, alone and in combination with standard-of-care chemotherapy agents. This work suggests that the addition of an HDAC inhibitor to upfront treatment may improve response.

FGF8 overexpression is an adverse independent prognostic factor in patients with upfront resected ESCC. Furthermore, FGF8 expression significantly correlates with ALK and EML4 amplification and may therefore qualify as a future therapeutic target.

IF-PTC from the isthmus is molecularly different compared with IF-PTC from the lobes. More data are needed to know if a change in surgical therapy is warranted in isthmic thyroid cancers relative to lobar cancers and if this molecular data should influence isthmic thyroid cancer management and monitoring.

In this case, lorlatinib effectively controlled the tumor and improved the patient's liver function and performance status. This case highlights the importance of adapting treatment strategies to manage adverse effects while ensuring the continued use of ALK inhibitors for optimal patient outcomes.

The predictive model composed of these features or combined with sex and smoking habits exhibited statistically significant differences for mutation status as a criterion (P<0.01). Collectively, the findings of the present study confirmed that, in addition to clinical characteristics, certain cytological and histological features of lung adenocarcinoma are associated with the mutational status of the tumor.

Finally, Shapley additive explanations (SHAP) was also used to explain the influence of modeling features on model prediction results. The SHAP results indicated that our models can well reflect the structural features of ALK inhibitors.

Clinical T1-2 N0 ALK-rearranged lung adenocarcinoma is an aggressive disease with a specific tropism for lymph nodes and the brain. High-grade tumors are predictive of nodal upstaging. Adjuvant treatment significantly improves DFS and OS in upstaged patients, highlighting the need for personalized preoperative staging and post-surgical management in this cohort.

In this particular case, treatment with crizotinib demonstrated some initial efficacy, which suggests that this might be a promising strategy for patients with advanced MPM with an ALK gene mutation. This required further research and evaluation in the future.

The detection of BRAF fusions and their many partners was enabled by the Afirma XA exome-enriched RNASeq panel. Although BRAF fusions occurred in only 0.2% of thyroid nodules, they were GSC-Suspicious and lacked typical BRAF/RAS mutations. Interestingly, expression signatures associated with malignancy varied by fusion partner.

It is feasible to yield actionable molecular testing results from cytology specimens within 2 to 3 hours of the patient's diagnostic procedure, and aspirate smears can be triaged for this use at the time of the rapid on-site evaluation. Targetable genetic alterations can be detected from destained cytology aspirate smear slides and unstained FFPE cell blocks with high accuracy, precision, and analytical sensitivity and specificity. The cost of each cartridge ranges from $127 to $462 and is covered by the average national reimbursement schemes.

Fusion detection using ctDNA CGP showed high concordance to tissue tests and high accuracy in predicting therapeutic response in NSCLC patients. The ctDNA CGP is expected to provide an important diagnostic option for fusion detection.

The routine use of RNA-based CGP analysis allows for the comprehensive detection of oncogenic fusions in patients with cancer. The diversity of tumor types in which actionable fusions were detected supports the broader utilization of CGP to potentially increase targeted therapy usage and improve outcomes across cancer subtypes.

Our standard operating procedure (SOP) was updated to perform orthogonal confirmation testing for stand-alone equivocal NTRK1/2 and equivocal NTRK3 (5' failure), but to ignore equivocal NTRK3 (5' intact) and report as NTRK2/3 indeterminate. Re-verification showed no change to ALK, ROS1, RET, MET ex14, and NTRK1 results. Sensitivity of NTRK2 detection was significantly increased (80% after orthogonal testing).

The AVENIO CGP assay is an end-to-end platform for tumor genomic profiling, with proven high analytical sensitivity and specificity. Its superb performance makes it well suited for translational research, providing deep genomic analyses to accelerate cancer research.

Screening for ALK rearrangements with IHC is both reliable and cost effective. In-house testing with IHC removes reliance on send-out testing for ALK detection, effectively cutting costs and decreasing TAT. Additionally, the creation of a reflex algorithm can improve lung cancer biomarker testing processes within hospitals.

This report offers a thorough characterization of expected prevalence and expression levels for CSFs and NDFs with an NGS study of a broad scope. We describe ESR1 fusions in a cohort of thousands of breast tumors and show lower median expression levels relative to NDFs such as ALK, ROS1, and RET fusions. Our findings suggest that some CSFs, like ESR1 fusions in breast cancer, may be the result of tandem duplication with upstream partners, and may be subclonal and acquired later in cancer progression.

Archer FusionPlex testing is a sensitive method of identifying recurrent and novel alterations in lung adenocarcinomas that are therapeutically actionable. Assessment of fusion/isoform-driven tumors demonstrates these alterations are acted upon. Public funding for all level 1 targeted therapies should be considered if the maximum benefit is to be derived from biomarker testing.

AFP, the targeted, breakpoint/fusion partner agnostic panel, outperformed 3 other established panels using real-world, fusion-driven thyroid cancers by an average detection frequency of 39%. Such findings demonstrate the importance in sequencing panel selection for fusion-driven thyroid cancer detection, and the potential downstream consequences for diagnostic utility and therapeutic intervention.

Genomic profiling yields clinically actionable information for approved therapies and evidence of resistance, and it may uncover rational therapeutic opportunities regardless of tumor type.

The AVENIO CGP Assay demonstrated high agreement with 2 established CGP tests, F1CDx and PGDx, in variant reporting, and closely aligned with F1CDx in HRDsig analysis across various tissue types. These results highlight the assay's reliability and demonstrate its utility in translational research.

Given the importance of timely, comprehensive molecular test results to inform appropriate treatment decisions in NSCLC and CRC, these results suggest that the rapid in-house GeneXus NGS system can reduce TAT with comparable failure rates and alteration detection rates compared to other testing methods. Further studies evaluating the impact of the rapid OPA compared to other methods on patient care, as well as the economics of different molecular tests, are ongoing.

In this real-world clinical dataset, WTS performed significantly worse than amplicon-based sequencing for detection of clinically meaningful fusions, predominantly due to a high QNS rate. It did not significantly increase the detection rate of novel fusions. Although amplicon-based methods may have limitations due to the inability to detect novel fusions, this can be overcome with design for additional targets, and is balanced by a superior ability to test a wide range of clinical samples without failure.
