Clinical intervention studies support the efficacy and safety of exercise programs as a treatment modality for non-small-cell lung cancer (NSCLC) during adjuvant/palliative treatment, but the effectiveness of real-world oncogeriatric services is yet to be established. We aimed to examine the effects of a 10-week structured and individualized multicomponent exercise program on physical/cognitive functioning and mental wellness in elderly patients with NSCLC under adjuvant therapy or palliative treatment. A non-randomized, opportunistic control, longitudinal-design trial was conducted on 26 patients with NSCLC stage I-IV. Of 34 eligible participants, 21 were allocated into two groups: (i) control group (n = 7) received usual medical care; and (ii) intervention group (n =19) received multicomponent program sessions, including endurance, strength, balance, coordination and stretching exercises. Tests included the Short Physical Performance Battery (SPPB), 5-m habitual Gait Velocity Test (GVT), Timed Up & Go Test (TUG), 6-Min Walk Test (6MWT), independence of activities in daily living (IADL), muscular performance, cognitive function, and quality of life, which were measured at baseline and after 10weeks of the program. Results revealed a significant groupxtime interaction for SPPB (p = 0.004), 5-m GVT (p = 0.036), TUG (p = 0.007), and muscular performance (chest and leg power; p < 0.001). Similarly, significant changes were observed between groups for cognitive functioning (p = 0.021) and quality of life for EUROQoL 5D (p = 0.006). Our findings confirm that a multicomponent exercise program improves measures of physical/cognitive functioning and quality of life in the elderly with NSCLC under adjuvant therapy or palliative treatment. This is an interesting and important study that adds to our current body of knowledge on the safety of exercise interventions, especially in the elderly with solid tumors.

Preoperative physical exercise protocols prior to cancer surgery increased in popularity over recent years; however, the beneficial effect of such protocols is not well established, with conflicting results reported. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effects of different modalities or combinations of preoperative exercise interventions and/or prehabilitation multicomponent training in patients with non-small-cell lung cancer (NSCLC) after surgery on the outcomes related to functional capacity, mental wellness and medical care. We searched in OVID Embase, Pubmed, Cochrane Library, CINAHL, Scopus, and Web of Science. Characteristics of studies and program results and outcome data were extracted. Changes between the intervention and control groups, from baseline to follow-up (standardized mean difference (SMD) or relative risk (RR) with 95% confidence interval (CI) for each intervention was pooled using weighted random-effects models). A total of 676 participants from 10 RCTs were included in the final analysis (aerobic training + inspiratory muscle training, n = 5; aerobic training + strength training + inspiratory muscle training, n = 2; aerobic training + strength training, n = 1; multicomponent training, n = 1; aerobic training alone, n = 1). The results showed intervention-induced improvement in walking endurance (SMD = 0.27; 95% CI, 0.11 to 0.44; I2= 0.0%), peak exercise capacity (SMD = 0.78; 95% CI, 0.35 to 1.21; I2= 76.7%), dyspnoea (SMD = −0.30; 95% CI, −0.51 to −0.10; I2 = 0.0%), risk of hospitalization (SMD = −0.58; 95% CI, −0.97 to −0.20; I2= 70.7%), and postoperative pulmonary complications (relative risk (RR) = 0.50; 95% CI, 0.39 to 0.66; I2= 0.0%). For the functional capacity and medical care parameters, preoperative combined aerobic, resistance, and inspiratory muscle training was shown to be effective if comprising one to four weeks, performing 1–3 sessions per week, with moderate intensity (50% for endurance capacity). Further studies with larger samples and higher methodological quality are needed to clarify the potential benefits of preoperative exercise training for patients with NSCLC.

PD-L1 expression in systemic immune cell populations as a potential predictive biomarker of responses to PD-L1/PD-1 blockade therapy in lung cancer
(MDPI, 2019) Bocanegra Gondán, Ana Isabel; Fernández Hinojal, Gonzalo; Zuazo Ibarra, Miren; Arasanz Esteban, Hugo; García Granda, María Jesús; Hernández, Carlos; Ibañez Vea, María; Hernandez Marin, Berta; Martínez Aguillo, Maite; Lecumberri, María José; Fernández de Lascoiti, Ángela; Teijeira, Lucía; Morilla Ruiz, Idoia; Vera García, Ruth; Escors Murugarren, David; Kochan, Grazyna; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
PD-L1 tumor expression is a widely used biomarker for patient stratification in PD-L1/PD-1 blockade anticancer therapies, particularly for lung cancer. However, the reliability of this marker is still under debate. Moreover, PD-L1 is widely expressed by many immune cell types, and little is known on the relevance of systemic PD-L1+ cells for responses to immune checkpoint blockade. We present two clinical cases of patients with non-small cell lung cancer (NSCLC) and PD-L1-negative tumors treated with atezolizumab that showed either objective responses or progression. These patients showed major differences in the distribution of PD-L1 expression within systemic immune cells. Based on these results, an exploratory study was carried out with 32 cases of NSCLC patients undergoing PD-L1/PD-1 blockade therapies, to compare PD-L1 expression profiles and their relationships with clinical outcomes. Significant differences in the percentage of PD-L1+ CD11b+ myeloid cell populations were found between objective responders and non-responders. Patients with percentages of PD-L1+ CD11b+ cells above 30% before the start of immunotherapy showed response rates of 50%, and 70% when combined with memory CD4 T cell profiling. These findings indicate that quantification of systemic PD-L1+ myeloid cell subsets could provide a simple biomarker for patient stratification, even if biopsies are scored as PD-L1 null
