ABSTRACT

AIM: To describe the clinical management and PD-L1 testing of patients with newly diagnosed stage IV non-small cell lung cancer (NSCLC) without driver mutations in Spain. METHODS: Multicenter, retrospective study. RESULTS: Among 297 evaluated patients, 89.2% received systemic treatment for stage IV disease, of whom 53.6% received platinum doublet therapy, 26.8% immunotherapy as monotherapy and 14.7% immunotherapy + chemotherapy, with 9.4% receiving treatment as part of a clinical trial. Treatment was initiated 1 month after histological diagnosis, with PD-L1 test results available in most cases (92.6%). PD-L1 testing was performed in 287 patients, 95.1% by in-house tests, mostly with the 22C3 pharmDx assay. The factor most strongly associated with treatment selection was, as expected, the expression of PD-L1. CONCLUSION: PD-L1 testing is implemented in clinical practice and seems to guide treatment decisions in patients with NSCLC in Spain.

ABSTRACT

BACKGROUND: AURA study reported 61% objective response rate and progression-free survival of 9.6 months with osimertinib in patients with EGFR/T790M+ non-small cell lung cancer. Due to lack of real-world data, we proposed this study to describe the experience with osimertinib in Spain. METHODS: Post-authorization, non-interventional Special Use Medication Program, multicenter, retrospective study in advanced EGFR/T790M+ non-small cell lung cancer. One hundred-fifty five patients were enrolled (August 2016-December 2018) from 30 sites. PRIMARY OBJECTIVE: progression-free survival. Secondary objectives: toxicity profile, objective response rate, and use of health service resources. RESULTS: 70% women, median age 66. 63.9% were non-smokers and 99% had adenocarcinoma. Most patients had received at least one prior treatment (97%), 91.7% had received previous EGFR-tyrosine kinase inhibitors and 2.8% osimertinib as first-line treatment. At data cutoff, median follow-up was 11.8 months. One hundred-fifty five patients were evaluable for response, 1.3% complete response, 40.6% partial response, 31% stable disease and 11.6% disease progression. Objective response rate was 42%. Median progression-free survival was 9.4 months. Of the 155 patients who received treatment, 76 (49%) did not reported any adverse event, 51% presented some adverse event, most of which were grade 1 or 2. The resource cost study indicates early use is warranted. CONCLUSION: This study to assess the real-world clinical impact of osimertinib showed high drug activity in pretreated advanced EGFR/T790M+ non-small cell lung cancer, with manageable adverse events. TRIAL REGISTRATION: Clinical trial registration number: NCT03790397 .

ABSTRACT

Renal cell carcinoma (RCC) with sarcomatoid features has an aggressive course. There is no standard treatment for this histological subtype. Some authors have previously reported the use of chemotherapy, but the activity of new agents against renal carcinoma with sarcomatoid differentiation has to be formally evaluated. Temsirolimus, an inhibitor of the mammalian target or rapamycin, is active in RCC, including those tumors with non-clear histologies. We have tested the activity of this agent in three consecutive patients. A first patient showed a rapid progression, dying 2 months after the diagnosis. The second patient showed clinical improvement and a partial response to lung metastasis that was maintained for 14 months. The third patient is still alive, evaluated as stable disease after 7 months on temsirolimus. Importantly, toxicity was not a main issue during the use of temsirolimus and only grade 2 hyperglycemia, asthenia, hyperlipidemia, and pleural effusion were detected. Temsirolimus is a valid therapy in this subset of patients, with some lasting stabilizations and with manageable toxicity.
