Comprehensive genomic profiling of penile squamous cell carcinoma and the impact of human papillomavirus status on immune-checkpoint inhibitor-related biomarkers. (PubMed, Cancer)

Penile squamous cell carcinoma (pSCC) is a rare and aggressive malignancy in the advanced setting, with poor prognosis and little success with immune-checkpoint inhibitors (ICIs) in an unselected patient approach. Human papillomavirus (HPV) infection is a known risk factor for pSCC; its impact on genomic tumor profiling is less defined. Using next-generation sequencing, we explored the genetic landscape and ICI-related biomarkers of pSCC and HPV-driven oncogenic molecular signatures. Our results indicate that HPV-positive and HPV-negative pSCCs are molecularly distinct tumors. Increased tumor mutational burden is associated with HPV-positive tumors, and could serve as a biomarker for predicting therapeutic response to ICI-based therapies. Our results support the growing literature indicating that HPV status in pSCC can be used to guide patient stratification in ICI-based clinical trials.

Clinical Application of Liquid Biopsy across Pan- Cancer: 4baseCare's Experience Using TarGT Indiegene- Liquid Biopsy NGS Panel (AMP Europe 2023)

The MRD estimation was evident in a breast cancer patient with ERBB2 amplification detected while the patient was on maintenance trastuzumab... This pan- cancer pilot study using the TarGT Indiegene Liquid Biopsy Panel supports the hypothesis that molecular information obtained from liquid biopsy can play a significant role in clinical decision-making, in addition to tissue mutation profiling. The results of this study demonstrate the potential clinical utility of this liquid biopsy panel in identifying actionable genomic alterations in patients with advanced stage cancer. These findings suggest that liquid biopsy has the potential to complement tissue biopsy and provide important molecular information to inform personalized treatment decisions for patients with cancer.

LY2874455 and Abemaciclib Reverse FGF3/4/19/CCND1 Amplification Mediated Gefitinib Resistance in NSCLC. (PubMed, Front Pharmacol)

Mechanistically, FGFs/CCND1 activated the MAPK pathway, which was abolished by the combination drugs. Our study provides a rationale for clinical testing of dual targeting FGFR and CCND1 with LY2874455 and abemaciclib in NSCLC patients who harbored FGF3/4/19/CCND1 amplification.

Clinical implication of plasma ctDNA features in HER2-positive gastric cancer treated with combinations of trastuzumab & anti-PD-1 agents (AACR 2022)

The ctDNA display a high consistency with tumor tissue for HER2 status. Compared to chemo-free regimens, chemo-containing regimens trend to demonstrate improved PFS and ORR in HER2-postive GC/GEJ, though no statistically significant. The HER2 amplification and immune-related negative gene alterations in ctDNA might be used as alternative biomarkers for predicting the efficacy of combining therapeutics containing trastuzumab and anti-PD-1 agents.

Comprehensive genomic proﬁling of penile squamous cell carcinoma and impact of HPV status on immune-checkpoint inhibition-related biomarkers. (ASCO-GU 2022)

"To our knowledge, our comprehensive NGS study of penile SCC somatic alterations is the largest to date. HPV16/18+ vs HPV16/18- penile SCC were molecularly distinct tumors, consistent with previous reports. Our finding that TMB-high was exclusive to patients with HPV16/18+ tumors requires confirmation in larger datasets and could be used for better patient stratification in ICI clinical trials."

[VIRTUAL] A Dramatic Change in Histopathologic Features of Melanoma After PD1 Blockade: Development of Bizarre-looking Cells (ASDP 2020)

She received one cycle of adjuvant therapy with pembrolizumab, but developed rapid progression of her melanoma both subjectively and on PET scan...Six months later she initiated trametinib but discontinued this due to intolerance...Updated genomic sequencing is pending, but tumor samples in patients with HPD typically demonstrate an increased mutation load compared to before ICI therapy. The histopathologic changes associated with HPD have not been well documented; this case suggests that dramatic alterations in cell cytology may also be a feature of hyperprogressive disease.
