Gefitinib in Non Small Cell Lung Cancer

Gefitinib is an oral, reversible, tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR) that plays a key role in the biology of non small cell lung cancer (NSCLC). Phase I studies indicated that the recommended dose of gefitinib was 250 mg/day. Rash, diarrhea, and nausea were the most common adverse events. The positive results obtained in early phase 2 clinical trials with gefitinib were not confirmed in large phase 3 trials in unselected patients with advanced NSCLC. The subsequent discovery that the presence of somatic mutations in the kinase domain of EGFR strongly correlates with increased responsiveness to EGFR tyrosine kinase inhibitors prompted phase 2 and 3 trials with gefitinib in the first line-treatment of EGFR-mutated NSCLC. The results of these trials have demonstrated the efficacy of gefitinib that can be now considered as the standard first-line treatment of patients with advanced NSCLC harbouring activating EGFR mutations

Intratumor Heterogeneity of ALK-Rearrangements and Homogeneity of EGFR-Mutations in Mixed Lung Adenocarcinoma

BACKGROUND: Non Small Cell Lung Cancer is a highly heterogeneous tumor. Histologic intratumor heterogeneity could be 'major', characterized by a single tumor showing two different histologic types, and 'minor', due to at least 2 different growth patterns in the same tumor. Therefore, a morphological heterogeneity could reflect an intratumor molecular heterogeneity. To date, few data are reported in literature about molecular features of the mixed adenocarcinoma. The aim of our study was to assess EGFR-mutations and ALK-rearrangements in different intratumor subtypes and/or growth patterns in a series of mixed adenocarcinomas and adenosquamous carcinomas. METHODS: 590 Non Small Cell Lung Carcinomas tumor samples were revised in order to select mixed adenocarcinomas with available tumor components. Finally, only 105 mixed adenocarcinomas and 17 adenosquamous carcinomas were included in the study for further analyses. Two TMAs were built selecting the different intratumor histotypes. ALK-rearrangements were detected through FISH and IHC, and EGFR-mutations were detected through IHC and confirmed by RT-PCR. RESULTS: 10/122 cases were ALK-rearranged and 7 from those 10 showing an intratumor heterogeneity of the rearrangements. 12/122 cases were EGFR-mutated, uniformly expressing the EGFR-mutated protein in all histologic components. CONCLUSION: Our data suggests that EGFR-mutations is generally homogeneously expressed. On the contrary, ALK-rearrangement showed an intratumor heterogeneity in both mixed adenocarcinomas and adenosquamous carcinomas. The intratumor heterogeneity of ALK-rearrangements could lead to a possible impact on the therapeutic responses and the disease outcomes

Elotuzumab plus pomalidomide and dexamethasone in relapsed/refractory multiple myeloma: a multicenter, retrospective real-world experience with 200 cases outside of controlled clinical trials

In the ELOQUENT-3 trial, the combination of elotuzumab, pomalidomide and dexamethasone (EloPd) proved a superior clinical benefit over Pd with a manageable toxicity profile, leading to its approval in relapsed/refractory multiple myeloma (RRMM), who had received at least two prior therapies, including lenalidomide and a proteasome inhibitor (PI). We report here a real-world experience of 200 RRMMs treated with EloPd in 35 Italian centers outside of clinical trials. In our dataset, the median number of prior lines of therapy was 2, with 51% of cases undergoing autologous stem cell transplant (ASCT) and 73% exposed to daratumumab. After a median follow-up of 9 months, 126 patients stopped EloPd, most of them (88.9%) because of disease progression. The overall response rate (ORR) was 55.4%, in line with the pivotal trial results. Regarding adverse events, our cohort experienced a toxicity profile similar to the ELOQUENT-3 trial, with no significant differences between younger (<70 years) and older patients. The median progression-free survival (PFS) was 7 months, shorter than that observed in the ELOQUENT-3, probably due to the different clinical characteristics of the two cohorts. Interestingly, the ISS stage III (HR:2.55) was associated with worse PFS. Finally, our series's median overall survival (OS) was shorter than that observed in the ELOQUENT-3 trial (17.5 versus 29.8 months). In conclusion, our real-world study confirms EloPd as a safe and possible therapeutic choice for RRMM who received at least two prior therapies, including lenalidomide and a PI

A Case of Critical Calcified Innominate Artery Stenosis Successfully Treated With the Shockwave Lithoplasty

Purpose: The Shockwave Lithoplasty System represents a novel technology combining a balloon angioplasty catheter with the use of sound waves. Evidences suggest that it is a reliable tool to overcome calcified stenosis in both peripheral and coronary arteries. Here, we describe the case of a patient with calcified innominate artery stenosis successfully treated with the Shockwave Lithoplasty System. Case Report: A 78-year-old woman with hypertension, and dyslipidemia, came to our observation for dizziness. Instrumental examinations showed critical calcified stenosis of the innominate artery. The lesion was successfully treated with the Shockwave Lithoplasty System and subsequent stent apposition. Final angiography demonstrated excellent position of the stent, good wall apposition, and confirmed patency of the right common and right vertebral artery origins. Conclusion: Our clinical experience demonstrates that Lithoplasty is safe and effective also for the treatment of supra-aortic vessels

Focus on Nintedanib in NSCLC and Other Tumors

Nintedanib is a new triple angiokinase inhibitor that potently blocks the proangiogenic pathways mediated by vascular endothelial growth factor (VEGF) receptors, platelet-derived growth factor (PDGF) receptors and fibroblast growth factor (FGF) receptors. Evidence about its efficacy in addition to second-line chemotherapy in non-small-cell-lung-cancer (NSCLC) has been produced by two large randomized phase III clinical trials (LUME-Lung-1 and LUME-Lung-2), conducted in patients with pretreated NSCLC, without major risk factors for bleeding. In the LUME-Lung-1, the addition of nintedanib to docetaxel significantly improved progression-free survival (PFS), that was the primary endpoint of the trial (3.4 vs 2.7 months, HR 0.79; p=0.0019). Furthermore, a significant improvement in median overall survival (OS) (from 10.3 to 12.6 months) was observed in patients with adenocarcinoma histology, with a greater advantage in patients with adenocarcinoma who progressed within 9 months after start of first line treatment (from 7.9 to 10.9 months), and in patients with adenocarcinoma most refractory to first line chemotherapy (from 6.3 to 9.8 months). Adverse events were more common in the docetaxel plus nintedanib group and they included diarrhea and increased liver enzymes, while no statistically significant increase in the incidence of bleeding and hypertension events by the addition of nintedanib was observed. On these bases, the combination of docetaxel and nintedanib can be considered a new option for the second-line treatment for patients with advanced NSCLC with adenocarcinoma histology. Future challenges are the identification of predictive factors to help the decision of using nintedanib in eligible patients

Validation of the new IASLC/ATS/ERS lung adenocarcinoma classification: a surgeon's perspective

The conclusions from the new IASLC/ATS/ERS lung adenocarcinoma classification portend important clinical consequences. The interpretation of the histological, biomolecular and radiological correlates of this classification not only allows for the definitive abandonment of the bronchoalveolar carcinoma definition but provides surgeons with significant clues to better understand the adenocarcinoma subsets and their surgical management. Indeed, the information will benefit surgeons who are fully involved in the lung cancer CT screening programs as well as in the diagnostic and therapeutic pathways of both early and locally advanced lung cancer. Moreover, intriguing perspectives are disclosing on the inclusion of the surgical modality among the ones used in the oligometastatic disease status. On the other hand, the new adenocarcinoma classification also emphasizes the need for surgeons working in a multidisciplinary environment to be thoroughly cognizant of the ever evolving lung cancer biomolecular knowledge and, in particular, of the potentially druggable somatic mutations in line with the modern professional profile of the so-called "surgeon scientist"
