The molecular pathways which promote lung cancer cell features have been broadly explored, leading to significant improvement in prognostic and diagnostic strategies. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have dramatically altered the treatment approach for patients with metastatic non-small cell lung cancer (NSCLC). Latest investigations by using next-generation sequencing (NGS) have shown that other oncogenic driver mutations, believed mutually exclusive for decades, could coexist in EGFR-mutated NSCLC patients. However, the exact clinical and pathological role of concomitant genomic aberrations needs to be investigated. In this systematic review, we aimed to summarize the recent data on the oncogenic role of concurrent genomic alterations, by specifically evaluating the characteristics, the pathological significance, and their potential impact on the treatment approach.

Safety and effectiveness of gemcitabine for the treatment of classic Kaposi’s sarcoma without visceral involvement

Therapeutic Advances in Medical Oncology (2022)

Giuseppe Badalamenti Lorena Incorvaia Laura Algeri Annalisa Bonasera Alessandra Dimino

Classic Kaposi's sarcoma (CKS) is a rare, multifocal, endothelial cell neoplasm that typically occurs in elderly people with previous infection by human herpes virus-8. Prospective trials are rare, and the choice of drugs relies on prospective trials performed on HIV-associated Kaposi's sarcoma (KS). Pegylated liposomal anthracyclines and taxanes are considered the standard first- and second-line chemotherapy, respectively. Despite the indolent biologic behavior, the natural history is characterized by recurrent disease. This condition of chronic administration of cytotoxic drugs is often associated with immediate/long-term adverse events.This was an observational, retrospective study to evaluate the effectiveness and safety of gemcitabine in patients with CKS. From January 2016 to September 2021, the patients were treated with gemcitabine 1000 mg/m2 on days 1 and 8, with cycles repeated every 21 days. The treatment was administered as first or second line.Twenty-seven (27) patients were included in the study. Twenty-one (21) out 27 patients (77.8%) achieved a partial response (PR), including 8 patients with major response (MR) (29.6%) and 13 patients with minor response (mR) (48.2%); 2 (7.4%) showed a complete response (CR), 3 (11.1%) a stable disease (SD), and 1 (3.7%) a progressive disease (PD). Tumor responses were generally rapid, with a median time to first response of 4 weeks (range, 3-12 weeks). Patients who responded had disease improvement with flattening of the skin lesions, decrease in the number of lesions, and substantial reduction in tumor-associated complications. Median duration of response was 19.2 months. Common adverse events were grades 1/2 thrombocytopenia, and grade 1 noninfectious fever. No patient discontinued treatment as a result of adverse events.Our study showed that gemcitabine is effective and well tolerated, acts rapidly on cutaneous lesions, and allows substantial symptom palliation, without dose-limiting toxicity. Gemcitabine represents a safe and effective option for the treatment of CKS.

Real life use of biomarkers of homologous recombination deficiency (HRD) status beyond BRCA to predict the effectiveness of PARP inhibitors in ovarian cancer patients.

Journal of Clinical Oncology (2023)

Lorena Incorvaia Chiara Brando Alessandro Perez Marco Bono D. Cancelliere

10592 Background: Testing for BRCA mutations (BRCAm) and genomic instability can identify epithelial ovarian cancer (OC) patients most likely to benefit from PARP-inhibitors (PARPi). However, current biomarkers of non- BRCA Homologous Recombination Repair (HRR) mutations are insufficient for guiding use of PARPi in the clinic. Despite non- BRCA HRR pathway gene mutations are rare, these patients may benefit from PARPi. Furthermore, recent preclinical findings showed that sensitivity to PARPi could be associated also with mutations in mismatch repair (MMR) genes, although sensitivity in the clinic is not proven. Methods: We report our real-life experience to assess the HRD status beyond BRCAm in newly-diagnosed OC patients, with the use of HRR gene panel and HRD genomic instability tests. After primary diagnosis, tumor and germline BRCA (g BRCA) status were assessed and, if BRCA WT, tumor HRR deficiency status were centrally determined by myChoiceCDx (Myriad) assay. NGS panel evaluating 20 MMR and HRR-genes beyond BRCA1/2 was proposed to patients with significant personal and/or family history of cancer, resulted negative to g BRCA testing. Results: From January 2017 to January 2023, 540 unselected epithelial OC patients, aging 27 to 81, were tested for tumor and g BRCA status; 109 were carriers of germline pathogenic or likely pathogenic variants (PVs) in BRCA1/2 genes (20.2%): 72 in BRCA1 (66.1%) and 37 in BRCA2 gene (33.9%). Additional 19 patients showed somatic PVs confined to tumor samples (3.5%).In the population of 70 BRCA WT patients tested by multigene panel testing, 14 germline PVs in HRR-associated (7.1%) or MMR-associated genes (12.8%) were found, including 5 in MUTYH (35.7%), 2 in ATM (14.3%), 2 in MLH1 (14.3%), 2 in PMS2 (14.3%), 1 in RAD51C (7.14%), 1 in RAD51D (7.14%), and 1 in CHEK2 gene (7.14%).Out of 72 samples analyzed by HRD genomic instability test, 23 cases were identified as HRD positive (31.9%), with a median GIS score of 65.5 (44-83). Median GIS were 35 (1-72) in the 6 cases of non- BRCA mutated tumors (8.3%), 40 (4-82) in the 17 tumor with non- BRCA variant of uncertain significance (VUS) (23.6%), and 27 (2-83) in the WT samples. Median GIS were significantly higher in tumors with PVs/VUS of RAD51 than BRIP1 (55.5 vs 35). Conclusions: HRRm gene panel and HRD genomic instability tests are not interchangeable to study HRR deficiency beyond BRCAm. HRD genomic instability test is effective to identify patients most likely to gain benefit from PARPi, but not for predicting familial risk of cancer. In our population, NGS panel evaluating HRR genes, beyond BRCA1/2, improved the detection rate of HRRm by 7%, with additional finding of MMR germline mutations, and important clinical implications for family members. Prospective data are expected to evaluate the effectiveness of PARPi in these population.
