1139PSensitizing HRAS overexpressing head and neck squamous cell carcinoma (HNSCC) to chemotherapy
ConclusionsERCC1 expression is a well-established biomarker for cisplatin resistance. Our study demonstrates that wtHRASov tumours represent a distinctive entity that strongly express ERCC1 and can be resensitized to cisplatin by tipifarnib.Legal entity responsible for the studyThe authors.FundingKura Oncology.DisclosureT.

248PPAM50 HER2-enriched subtype and pathological complete response in HER2-positive early breast cancer: A meta-analysis
ConclusionsHER2-E subtype identifies patients with a higher likelihood of achieving a pCR following anti-HER2-based NAT, with or without CT. In the latter case, albeit limited by small casuistry, the association seems stronger in HR+ tumors. This suggests that strategies to escalate or de-escalate systemic therapy in HER2+ tumors would benefit from incorporating intrinsic subtypes.Legal entity responsible for the studyThe authors.FundingHas not received any funding.DisclosureF.

1587TiPCANOPY phase III program: Three studies evaluating canakinumab in patients with non-small cell lung cancer (NSCLC)
AbstractBackgroundThe presence of inflammatory mediators in the tumor microenvironment may have pro or antitumorigenic effects. The cytokine interleukin-1 β (IL-1β) affects multiple aspects of the tumor microenvironment promoting carcinogenesis, tumor invasiveness, and immunosuppression. Canakinumab is a human monoclonal antibody with high affinity and specificity for IL-1β. Results of the phase III Canakinumab Anti-Inflammatory Thrombosis Outcomes Study (CANTOS) have shown that IL-1β inhibition with canakinumab was associated with reduced lung cancer incidence and mortality, providing a rationale to investigate the po...

12PEGFR-mediated PD-L1 upregulation in HER2+ breast cancer (BC) cell line models
ConclusionsThe results indicate PD-L1 expression can be altered by manipulation of EGFR activity in HER2+ breast cancer cell line models. The development of targeted therapy resistance can interfere with the ability of EGFR to impact PD-L1 levels. Further examination of EGFR and PD-L1 is warranted in HER2+ breast cancer models.Legal entity responsible for the studyThe authors.FundingCancer Clinical Research Trust.DisclosureA.

1588TiPThe elderly patient individualized chemotherapy (EPIC) trial, a study for an aged population of non-small cell lung cancer
AbstractBackgroundNon-small cell lung cancer (NSCLC) is one of the commonest disease worldwide and the leading cause of cancer-related death. Incidence increases with age and reaches a peak in senility, when patients ’ (pts) comorbidities may limit the efficacy of treatments. At this time, no homogeneous indications are available for elderly NSCLC pts and the optimization of treatment, with the lowest side effects, is still an unmet need, also after the introduction of innovative drugs. The ribonucleotide redu ctase catalytic subunit M1(RRM1), the DNA-excision repair protein ERCC1 and the thymidylate synthetase (TS) are ...
