Spatially Preserved Multi-Region Transcriptomic Subtyping and Biomarkers of Chemoimmunotherapy Outcome in Extensive-Stage Small Cell Lung Cancer.

Purpose: Transcriptomic subtyping holds promise for personalized therapy in extensive-stage small cell lung cancer (ES-SCLC). In this study, we aimed to assess intratumoral transcriptomic subtype diversity and to identify biomarkers of long-term chemoimmunotherapy benefit in human ES-SCLC.

Experimental Design: We analyzed tumor samples from 58 patients with ES-SCLC enrolled in two multicenter single-arm phase IIIb studies evaluating frontline chemoimmunotherapy in Spain: n = 32 from the IMfirst trial and n = 26 from the CANTABRICO trial.

The S-REAL study: Spanish real-world data on unresectable stage III NSCLC patients treated with durvalumab after chemoradiotherapy.

Objectives: The S-REAL study aimed to assess the effectiveness of durvalumab as consolidation therapy after definitive chemoradiotherapy (CRT) in a real-world cohort of patients with locally advanced, unresectable stage III non-small cell lung cancer (LA-NSCLC) included in a Spanish early access program (EAP).

Methods: In this multicentre, observational, retrospective study we analysed data from patients treated in 39 Spanish hospitals, who started intravenous durvalumab (10 mg/kg every 2 weeks) between September 2017 and December 2018. The primary endpoint was progression-free survival (PFS).

Neoadjuvant chemotherapy with dose-dense MVAC in muscle-invasive bladder cancer: a tertiary center experience.

Purpose: Neoadjuvant chemotherapy in muscle-invasive bladder cancer (MIBC) patients has proven beneficial in overall survival. However, the optimal regimen is still a matter of debate.

Materials And Methods: In this retrospective analysis, we evaluate the results obtained in 42 patients treated in our center with 4 cycles of neoadjuvant dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin (dd-MVAC) followed by radical cystectomy from August 2015 to October 2020.

Cost-effectiveness of atezolizumab versus pembrolizumab as first-line treatment in PD-L1-positive advanced non-small-cell lung cancer in Spain.

Background: Atezolizumab has recently been approved for first-line treatment of high PD-L1 expression metastatic Non-Small-Cell Lung Cancer (NSCLC) patients with no EGFR or ALK mutations, on the basis of the IMpower110 trial. This study aims to estimate the cost-effectiveness of atezolizumab compared with pembrolizumab among these patients in Spanish settings, based on the results of the two cut-offs of the IMpower110 study.

Methods: A three-state partitioned-survival model was adapted to Spanish settings to calculate health outcomes and costs over a lifetime horizon.

Alectinib after failure to crizotinib in patients with ALK-positive non-small cell lung cancer: results from the Spanish early access program.

This retrospective observational study analyzed the clinical characteristics, treatment patterns and outcomes of 120 patients with advanced ALK-positive non-small-cell lung cancer (ALK+ NSCLC) according to data collected between November 2019 and October 2020 in 38 Spanish hospitals. Patients had progressed after 1-5 prior treatment lines (which included crizotinib in any prior line) and received subsequent therapy with alectinib in a local expanded access program. Median age was 58.
