Stereotactic irradiation (SBRT) is a standard of care for inoperable stage I lung cancer and brain oligometastases from lung cancer but is controversial for extracranial oligometastases. We assessed ...outcomes of lung cancer patients with extracranial metastases in oligometastatic, oligorecurrent, oligopersistent and oligoprogressive settings ("oligometastatic spectrum") under strategies using SBRT +/- systemic treatments.
A retrospective multicentric study of consecutive lung cancer adult patients with 1-5 extracranial metastases treated with SBRT was conducted.
Of 91 patients (99 metastases, median age 63, 64.8% adenocarcinomas, 19.8% molecular alterations), 11% had oligometastases, 49.5% oligorecurrence, 19.8% oligopersistence and 19.8% oligoprogression. Of 36% of patients under systemic treatments at initiation of SBRT, systemic treatment interruption was performed in 58% of them. With median follow up of 15.3 months, crude local control at irradiated metastases was 91%, while median distant progression-free survival (dPFS) and overall survival were 6.3 and 28.4 months (2-year survival 54%). Initial nodal stage and oligometastatic spectrum were prognostic factors for dPFS; age, initial primary stage and oligometastatic spectrum were prognostic factors for survival on multivariate analysis. Patients with oncogene-addicted tumors more frequently had oligoprogressive disease. Repeat ablative irradiations were preformed in 80% of patients who had oligorelapses. Worst acute toxicities consisted of 5.5% and one late toxic death occurred.
The oligometastatic spectrum is a strong prognosticator in patients undergoing SBRT for extracranial metastases. Median survival was over two years but dPFS was about 6 months. Continuation of systemic therapy in oligoprogressive patients should be investigated.

Most patients with lung cancer are smokers and are of advanced age. They are therefore at high risk of having age- and lifestyle-related comorbidities. These comorbidities are subject to treatment or ...even polypharmacy. There is growing evidence of a link between lung cancer, comorbidities and medications. The relationships between these entities are complex. The presence of comorbidities and their treatments influence the time of cancer diagnosis, as well as the diagnostic and treatment strategy. On the other hand, cancer treatment may have an impact on the patient's comorbidities such as renal failure, pneumonitis or endocrinopathies. This review highlights how some comorbidities may have an impact on lung cancer presentation and may require treatment adjustments. Reciprocal influences between the treatment of comorbidities and anticancer therapy will also be discussed.
Background: We aimed to assess the clinical utility of a previously published score combining the total metabolic tumor volume (TMTV) on baseline FDG-PET/CT and pretreatment derived from the ...neutrophils to lymphocytes ratio (dNLR) for prognostication in NSCLC patients undergoing first-line immunotherapy (IT). Methods: In this multicenter retrospective study, 63 advanced NSCLC patients with a PD-L1 tumor proportion score (TPS) ≥50%, who underwent FDG-PET/CT before first-line IT, treated from January 2017 to September 2019, were enrolled. Associations between this score and the progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and overall response rate (ORR) were evaluated. Results: The median (m) PFS and mOS were 7.7 (95% CI 4.9–10.6) and 12.1 (8.6–15.6) months, respectively, and DCR and ORR were 65% and 58%, respectively. mOS was 17.9 months (14.6 not reached) for the good group versus 13.8 (95%CI 8.4–18.9) and 6.6 (CI 2.0–11.2) months for the intermediate and poor groups, respectively. mPFS was 15.1 (95%CI 12.1–20.0) months for the good group versus 5.2 (1.9–8.5) and 1.9 (95%CI 1.3–2.5) months for the intermediate and poor groups, respectively. The poor prognosis group was associated with DCR and ORR (p < 0.05). Conclusions: The metabolic score combining TMTV on the baseline FDG-PET/CT scan and pretreatment dNLR was associated with the survival and response in a cohort of advanced NSCLC patients with ≥50% PD-L1 receiving frontline IT.

Background
The KEYNOTE‐024 trial demonstrated that pembrolizumab, a PD‐1 inhibitor, significantly improves progression‐free survival (PFS) and overall survival (OS) in selected patients with ...previously untreated advanced non–small cell lung cancer (NSCLC) with a PD‐L1 tumor proportion score (TPS) ≥50% and without EGFR/ALK aberrations. The main aim of this study was to report the efficacy and safety profile of pembrolizumab in real‐life conditions.
Method
This was a French retrospective multicenter longitudinal study of 108 consecutive patients with advanced NSCLC, a PD‐L1 TPS ≥50% and without EGFR/ALK aberrations who were treated by pembrolizumab, in first line. Patient data were obtained from medical files.
Results
The main characteristics of the cohort were: median age range 66.7 37‐87 years, 64.8% male, 23.1% with a performance status (PS) of 2, and 88.9% current or former smokers. Eighty‐seven percent had stage IV NSCLC at diagnosis, 9.2% untreated brain metastases at inclusion,. With a median follow‐up of 8.2 months, the median PFS was 10.1 months (95% CI, 8.8‐11.4). The objective response rate was 57.3% (complete response 2.7%, partial response 54.6%). Disease control rate was 71.1%. At 6 months, the OS rate estimated was 86.2%. Treatment‐related adverse events (AE) of grade 3 occurred in 8% of patients. There were no grade 4 or 5 AEs.
Conclusion
In a real‐life cohort of advanced NSCLC patients (including PS 2 and untreated brain metastases), with PD‐L1 TPS ≥50%, pembrolizumab demonstrates similar PFS to the pivotal clinical trial.
This retrospective multicenter longitudinal study was intended to report the efficacy and safety profile of pembrolizumab in real‐life conditions for the first‐line treatment of advanced squamous none small‐cell lung cancer. The median progression free survival was 10.1 months (95% CI, 8.8‐11.4) and the treatment‐related adverse events of grade 3 occurred in 8% of patients. This study demonstrates similar progression‐free survival to KEYNOTE‐024.

This two-step study evaluated the cost-effectiveness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for presurgery staging of non-small cell lung cancer (NSCLC) in ...France (EVIEPEB; ClinicalTrial.gov identifier NCT00960271). Step 1 consisted of a high-benchmark EBUS-TBNA-training program in participating hospital centers. Step 2 was a prospective, national, multicenter study on patients with confirmed or suspected NSCLC and an indication for mediastinal staging with at least one lymph node > 1 cm in diameter. Patients with negative or uninformative EBUS-TBNA and positron-emission tomography-positive or -negative nodes, respectively, underwent either mediastinoscopy or surgery. Direct costs related to final diagnosis of node status were prospectively recorded. Sixteen of 22 participating centers were certified by the EBUS-TBNA-training program and enrolled 163 patients in Step 2. EBUS-TBNA was informative for 149 (91%) patients (75 malignant, 74 non-malignant) and uninformative for 14 (9%). Mediastinoscopy was avoided for 80% of the patients. With a 52% malignant-node rate, EBUS-TBNA positive- and negative-predictive values, respectively, were 100% and 90%. EBUS-TBNA was cost-effective, with expected savings of €1,450 per patient, and would have remained cost-effective even if all EBUS-TBNAs had been performed under general anesthesia or the cost of the procedure had been 30% higher (expected cost-saving of €994 and €1,427 per patient, respectively). After EBUS-TBNA training and certification of participating centers, the results of this prospective multicenter study confirmed EBUS-TBNA cost-effectiveness for NSCLC staging.

Background
In Europe, few data regarding the characteristics of
EGFR
exon 20 insertion (20ins) mutations in non-small cell lung cancer (NSCLC) are available.
Objective
Using a large real-world ...cohort, we assessed the incidence, characteristics, and outcomes of patients with non-squamous (nsq) NSCLC harboring
EGFR
exon 20ins.
Patients and Methods
The Epidemio-Strategy and Medical Economics advanced and metastatic lung cancer data platform including advanced/metastatic nsqNSCLC patients from January 2015 was analyzed (cut-off date: June 30, 2020). Characteristics, epidermal growth factor receptor (
EGFR
) mutation and other mutations, treatment patterns, and clinical outcomes were assessed for patients harboring
EGFR
exon 20ins, common
EGFR
mutations, other
EGFR
mutations, and wild-type
EGFR
. Survival parameters were estimated by the Kaplan-Meier method in these four groups.
Results
Out of 9435 nsqNSCLC patients tested for
EGFR
, 1549 (16.4%) had a mutation, including 61 with
EGFR
exon 20ins (3.9% of all mutated
EGFR
). These 61 patients had a mean age of 63.6 years, were mostly female (68.9%) and non-smokers (55.7%), with de novo stage IV disease (73.8%) and performance status 0–1 (76.9%). Almost all patients (95.1%) with exon 20ins received systemic therapy (median, three lines). First-line systemic treatments consisted mainly of combination chemotherapy (70.7%), single-agent EGFR tyrosine kinase inhibitors (10.3%), and single-agent immunotherapy (5.2%). After a median follow-up of 25.0 (95% confidence interval CI 22.3–32.4) months, the median real-world overall survival was 24.3 (19.1–32.6) months in patients with exon 20ins compared to 35.4 (95% CI 32.6–37.5) in patients with common
EGFR
mutation (
n
= 1049) (
p
= 0.049) and 19.6 (95% CI 18.6–20.5) in patients with wild-type
EGFR
(
n
= 7866) (
p
= 0.2).
Conclusions
This large national study in nsqNSCLC patients confirms that
EGFR
exon 20ins is a rare condition (0.6%). The prognosis associated with exon 20ins appears to be in line with that of wild-type
EGFR
, but worse than common
EGFR
mutations, highlighting the need for advancements for this rare population.

Genomic and immunologic tumor biomarker testing has dramatically changed the prognosis of patients, particularly those treated for advanced/metastatic non-squamous non-small-cell lung cancer (aNSCLC) ...when access to targeted agents is available. It remains unclear whether older patients have access to therapy-predictive biomarker testing techniques in the same proportion as younger patients. This study aims to compare the proportion of biomarker testing performed in non-squamous aNSCLC at diagnosis between patients aged ≥70 years old and their younger counterparts.
We conducted a retrospective analysis using the Epidemio-Strategy and Medical Economics (ESME) Advanced or Metastatic Lung Cancer Data Platform, a French multicenter real-life database. All patients with non-squamous aNSCLC diagnosed between 2015 and 2018 were selected. Biomarker testing corresponded to at least one molecular alteration and/or PD-L1 testing performed within 1 month before or 3 months after the aNSCLC diagnosis.
In total, 2848 patients aged ≥70 years and 6900 patients aged <70 years were included. Most patients were male. The proportion of current smokers at diagnosis was higher in the <70 years group (42% vs. 17%,
< 0.0001). There was no significant difference in the proportion of biomarker testing performed between the two groups (63% vs. 65%,
= 0.15).
mutations were significantly more common in the older group (22% vs. 12%,
< 0.0001) and
mutations significantly more frequent in the younger group (39% vs. 31%
< 0.0001). The distribution of other driver mutations (
V600E,
and
) was similar across age. In the multivariable analysis, factors independently associated with biomarker testing were gender, smoking status, history of COPD, stage at primary diagnosis, and histological type.
Age is not a barrier to biomarker testing in patients with aNSCLC.

Concomitant radiochemotherapy (RTCT) is the standard treatment for unresectable stage III non-small cell lung cancer (NSCLC). However, in patients with a peripheral primary tumor, the irradiated ...volume may include a large portion of normal lung and RT-CT is not possible. This multicenter phase II trial in unresectable stage III NSCLC with peripheral primary tumor evaluated the feasibility of stereotactic body radiation therapy (SBRT) in peripheral tumor after concomitant radio-chemotherapy (RT-CT). Nineteen patients were included and analyzed (median age, 60.9 years; male, 78%; adenocarcinoma, 74%; median size of peripheral primary tumor, 19 mm). At 6 months, the disease control rate was 79% (15/19). SBRT toxicity was generally mild with one (5%) patient having grade 3 lung toxicity. Recruitment for this study was stopped prior to completion, firstly due to the approval of adjuvant durvalumab after RT-CT, which was not anticipated in the design, and secondly due to the small number of stage III NSCLC patients with a peripheral tumor that was accessible to SBRT. Nevertheless, the combination of RT-CT and SBRT appeared to be feasible and safe.

An association between HIV infection and chronic obstructive pulmonary disease (COPD) has been observed in several studies.
we conducted a review of the literature linking HIV infection to COPD, ...focusing on clinical and epidemiological data published before and during widespread highly active antiretroviral therapy (HAART).
Interactions between HIV infection and COPD appear to be influenced by multiple factors. In particular, the bronchopulmonary tract can be damaged by HIV infection, the immunodeficiency it induces, and the resulting increase in the risk of pulmonary infections. In addition, the prevalence of smoking and intravenous drug use is higher in HIV-infected populations, also increasing the risk of COPD. Before the advent of HAART, respiratory tract infections probably played a major role. Since the late 1990s and the widespread use of HAART, the frequency of opportunistic infections has fallen but new complications have emerged as life expectancy has increased.
given the high prevalence of smoking among HIV-infected patients, COPD may contribute significantly to morbidity and mortality in this setting.

Dabrafenib plus trametinib combination is approved in Europe for
V600E-mutant metastatic non-small-cell lung cancer (NSCLC). The objective of this study was to assess efficacy and safety of this ...combination in a real-world setting. This retrospective multicentric study included 40 patients with advanced NSCLC harboring
V600E mutation and receiving dabrafenib plus trametinib. The median progression-free survival (PFS) and overall survival (OS) were 17.5 (95% CI 7.1-23.0) months and 25.5 (95% CI 16.6-not reached) months in the entire cohort, respectively. For the 9 patients with first-line treatment, median PFS was 16.8 (95% CI 6.1-23.2) months and median OS was 21.8 (95% CI 1.0-not reached) months; for the 31 patients with second-line or more treatments, median PFS and OS were 16.8 (95% CI 6.1-23.2) months and 25.5 (95% CI 16.6-not reached) months, respectively. Adverse events led to permanent discontinuation in 7 (18%) patients, treatment interruption in 8 (20%) and dose reduction in 12 (30%). In conclusion, these results suggest that efficacy and safety of dabrafenib plus trametinib combination in patients with
V600E metastatic NSCLC are comparable in a real-world setting and in clinical trials for both previously untreated and treated patients.
