RESUMEN
Introduction: The Thoracic Centers International coronavirus disease 2019 (COVID-19) Collaboration (TERAVOLT) registry found approximately 30% mortality in patients with thoracic malignancies during the initial COVID-19 surges. Data from South Africa suggested a decrease in severity and mortality with the Omicron wave. Our objective was to assess mortality of patients with thoracic malignancies with the Omicron-predominant wave and evaluate efficacy of vaccination. Methods: A prospective, multicenter observational study was conducted. A total of 28 institutions contributed data from January 14, 2022, to February 4, 2022. Inclusion criteria were any thoracic cancer and a COVID-19 diagnosis on or after November 1, 2021. End points included mortality, hospitalization, symptomatic COVID-19 infection, asymptomatic COVID-19 infection, and delay in cancer therapy. Analysis was done through contingency tables and a multivariable logistic model. Results: We enrolled a total of 346 patients. Median age was 65 years, 52.3% were female, 74.2% were current or former smokers, 86% had NSCLC, 72% had stage IV at time of COVID-19 diagnosis, and 66% were receiving cancer therapy. Variant was unknown for 70%; for those known, Omicron represented 82%. Overall mortality was 3.2%. Using multivariate analysis, COVID-19 vaccination with booster compared with no vaccination had a protective effect on hospitalization or death (OR = 0.30, confidence interval: 0.15-0.57, p = 0.0003), whereas vaccination without booster did not (OR = 0.64, confidence interval: 0.33-1.24, p = 0.1864). Cancer care was delayed in 56.4% of the patients. Conclusions: TERAVOLT found reduced patient mortality with the most recent COVID-19 surge. COVID-19 vaccination with booster improved outcomes of hospitalization or death. Delays in cancer therapy remain an issue, which has the potential to worsen cancer-related mortality.
RESUMEN
INTRODUCTION: Patients with thoracic malignancies are at increased risk for mortality from coronavirus disease 2019 (COVID-19), and a large number of intertwined prognostic variables have been identified so far. METHODS: Capitalizing data from the Thoracic Cancers International COVID-19 Collaboration (TERAVOLT) registry, a global study created with the aim of describing the impact of COVID-19 in patients with thoracic malignancies, we used a clustering approach, a fast-backward step-down selection procedure, and a tree-based model to screen and optimize a broad panel of demographics and clinical COVID-19 and cancer characteristics. RESULTS: As of April 15, 2021, a total of 1491 consecutive eligible patients from 18 countries were included in the analysis. With a mean observation period of 42 days, 361 events were reported with an all-cause case fatality rate of 24.2%. The clustering procedure screened 73 covariates in 13 clusters. A further multivariable logistic regression for the association between clusters and death was performed, resulting in five clusters significantly associated with the outcome. The fast-backward step-down selection procedure then identified the following seven major determinants of death: Eastern Cooperative Oncology Group-performance status (ECOG-PS) (OR = 2.47, 1.87-3.26), neutrophil count (OR = 2.46, 1.76-3.44), serum procalcitonin (OR = 2.37, 1.64-3.43), development of pneumonia (OR = 1.95, 1.48-2.58), C-reactive protein (OR = 1.90, 1.43-2.51), tumor stage at COVID-19 diagnosis (OR = 1.97, 1.46-2.66), and age (OR = 1.71, 1.29-2.26). The receiver operating characteristic analysis for death of the selected model confirmed its diagnostic ability (area under the receiver operating curve = 0.78, 95% confidence interval: 0.75-0.81). The nomogram was able to classify the COVID-19 mortality in an interval ranging from 8% to 90%, and the tree-based model recognized ECOG-PS, neutrophil count, and c-reactive protein as the major determinants of prognosis. CONCLUSIONS: From 73 variables analyzed, seven major determinants of death have been identified. Poor ECOG-PS was found to have the strongest association with poor outcome from COVID-19. With our analysis, we provide clinicians with a definitive prognostication system to help determine the risk of mortality for patients with thoracic malignancies and COVID-19.

Dabrafenib plus trametinib combination is approved in Europe for BRAF 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 BRAF 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 BRAF V600E metastatic NSCLC are comparable in a real-world setting and in clinical trials for both previously untreated and treated patients.
RESUMEN
INTRODUCTION: About 2-3% of non-small-cell lung cancers (NSCLCs) harbor MET exon-14-skipping (METex14) mutations. Efficacy of the MET-inhibitor crizotinib has been reported, but progression-free survival (PFS) was very short. Immune-checkpoint inhibitors (ICIs) have become a cornerstone of NSCLC treatment but appear to be less effective in non-smokers and against tumors exhibiting oncogenic addiction. We describe 6 remarkable (PFS exceeding 18 months) and durable responses to ICIs of NSCLCs harboring a METex14 mutation. METHODS: Each patient's clinical and biological characteristics, and tumor responses after ICIs were examined. Complete tumor-DNA sequencing was available after starting second-line ICIs, which followed first-line chemotherapy. Tumor-cell programmed cell-death protein-1 ligand-1 (PD-L1) expression on tumor cells was evaluated using antibody clone E1L3N (Cell Signaling Technology). RESULTS: Among 25 patients with METex14-mutated NSCLCs, 13 of whom were ICI-treated, 6 had prolonged responses: 5 women, 1 man; 57-80 years old; 3 never-smokers, 1 ex-smoker and 2 smokers; 5 adenocarcinomas, 1 sarcomatoid carcinoma; 5 received nivolumab, 1 pembrolizumab. No EGFR, BRAF or KRAS mutations (only 1 minority KRAS mutation), or ALK or ROS translocations were detected. No concurrent MET amplification was observed. Tumor-mutation burden was low (<10 mutations/Mb) in 3 tested tumors. Four partial and 2 complete responses were obtained during the first 3 months for 5 patients, while pseudoprogression was initially observed in 1. Tolerance was excellent, with only 1 grade-3 immune-related adverse event. Response was maintained for 18-49 months. CONCLUSION: ICIs could be considered to treat patients whose NSCLCs harbor a METex14 mutation. More biological marker data are needed to identify which patients are most likely to benefit from ICIs.

BACKGROUND: Respiratory infections are a major threat for lung recipients. We aimed to compare with a monocentric study the impact of late viral and bacterial respiratory infections on the graft function. METHODS: Patients, who survived 6 months or more following lung transplantation that took place between 2009 and 2014, were classified into three groups: a viral infection group (VIG) (without any respiratory bacteria), a bacterial infection group (BIG) (with or without any respiratory viruses), and a control group (CG) (no documented infection). Chronic lung allograft dysfunction (CLAD) and acute rejection were analysed 6 months after the inclusion in the study. RESULTS: Among 99 included lung recipients, 57 (58%) had at least one positive virological respiratory sample during the study period. Patients were classified as follows: 38 in the VIG, 25 in the BIG (among which 19 co-infections with a virus) and 36 in the CG. The BIG presented a higher initial deterioration in lung function (p = 0.05) than the VIG. But 6 months after the infection, only the VIG presented a median decrease of forced expiratory volume in 1 s; - 35 mL (IQR; - 340; + 80) in the VIG, + 140 mL (+ 60;+ 330) in the BIG and + 10 (- 84;+ 160) in the CG, p < 0.01. Acute rejection was more frequent in the VIG (n = 12 (32%)), than the BIG (n = 6 (24%)) and CG (n = 3 (8%)), p < 0.05, despite presenting no more CLAD (p = 0.21). CONCLUSIONS: Despite a less severe initial presentation, single viral respiratory infections seem to lead to a greater deterioration in lung function, and to more acute rejection, than bacterial infections.

Immunotherapy is becoming a standard of care for many cancers. Immune-checkpoint inhibitors (ICI) can generate immune-related adverse events. Interstitial lung disease (ILD) has been identified as a rare but potentially severe event.Between December 2015 and April 2016, we conducted a retrospective study in centres experienced in ICI use. We report the main features of ICI-ILD with a focus on clinical presentation, radiological patterns and therapeutic strategies.We identified 64 (3.5%) out of 1826 cancer patients with ICI-ILD. Patients mainly received programmed cell death-1 inhibitors. ILD usually occurred in males, and former or current smokers, with a median age of 59â years. We observed 65.6% grade 2/3 severity, 9.4% grade 4 severity and 9.4% fatal ILD. The median (range) time from initiation of immunotherapy to ILD was 2.3 (0.2-27.4) months. Onset tended to occur earlier in lung cancer versus melanoma: median 2.1 and 5.2â months, respectively (p=0.02). Ground-glass opacities (81.3%) were the predominant lesions, followed by consolidations (53.1%). Organising pneumonia (23.4%) and hypersensitivity pneumonitis (15.6%) were the most common patterns. Overall survival at 6â months was 58.1% (95% CI 37.7-73.8%).ICI-ILD often occurs early and displays suggestive radiological features. As there is no clearly identified risk factor, oncologists need to diagnose and adequately treat this adverse event.

RATIONALE: Cystic lung light chain deposition disease (LCDD) is a severe and rare form of nonamyloid kappa light chain deposits localized in the lung, potentially leading to end-stage respiratory insufficiency. OBJECTIVES: To assess the outcome after lung transplantation (LT) in this setting with particular attention to disease recurrence. METHODS: We conducted a retrospective multicenter study of seven patients who underwent LT for cystic lung LCDD in France between September 1992 and June 2012 in five centers. MEASUREMENTS AND MAIN RESULTS: In total, five females and two males (mean age, 39.1 ± 5.3 yr) underwent one single LT or seven double LT (one retransplantation). Before LT, the patients showed a constant obstructive ventilatory pattern with low carbon monoxide diffusing capacity and resting hypoxemia. Lung computed tomography revealed widespread cysts with occasional micronodulations. No extrapulmonary disease or plasma cell neoplasm was detected. The serum-free kappa/lambda light chain ratio was increased in three cases. The median follow-up after LT was 56 months (range, 1-110 mo). Kaplan-Meier survival was 85.7, 85.7, and 64.3% at 1, 3, and 5 years, respectively. Three patients died from multiorgan failure (n = 1), chronic rejection (n = 1), and breast cancer (n = 1) at 23 days, 56 months, and 96 months, respectively. At the end of follow-up, no patients showed recurrence on imaging or histopathology. CONCLUSIONS: This small case series confirms that cystic lung LCDD is a severe disease limited to the lung, affecting mostly young females. LT appears to be a good therapeutic option allowing for satisfactory long-term survival. We found no evidence of recurrence of the disease after LT.

BACKGROUND: New methods of solid-phase assays, such as Luminex assay, with high sensitivity in detecting anti-human leukocyte antigen (HLA) antibodies (Abs), have increased the proportion of sensitized candidates waiting for lung transplantation (LTx). However, how to apply these results clinically during graft allocation is debated: strict exclusion of candidates with Luminex-positive results can lead to lost opportunities for Tx. We retrospectively analyzed the clinical impact of pre-LTx Luminex-detected Abs on post-LTx outcomes for patients who underwent LTx before the availability of Luminex assay. METHODS: We analyzed data for 56 successive patients who underwent LTx before 2008 and were considered to not have anti-HLA Abs by then-available methods of detection at the date of their LTx. Pre-LTx sera from these patients were retested by Luminex assay. Using log-rank test, freedom from bronchiolitis obliterans syndrome (BOS) and graft survival were compared between patients with and without pre-LTx Luminex-detected anti-HLA Abs classes I and II and donor-specific Abs (DSA) classes I and II. RESULTS: Freedom from bronchiolitis obliterans syndrome was lower, and mortality was higher for patients with than those without pre-LTx Luminex-detected DSA class II (P=0.004 and P=0.007, respectively) but did not differ for patients with and without DSA class I or anti-HLA Abs class I or II. CONCLUSIONS: It suggests to avoid attributing graft with forbidden antigens to sensitized candidates with Luminex-detected DSA class II and to evaluate the role of specific posttransplantation protocols for LTx candidates who require emergency LTx.

OBJECTIVES: It was previously shown that dehydroepiandrosterone (DHEA) reverses chronic hypoxia-induced pulmonary hypertension (PH) in rats, but whether DHEA can improve the clinical and hemodynamic status of patients with PH associated to chronic obstructive pulmonary disease (PH-COPD) has not been studied whereas it is a very severe poorly treated disease. PATIENTS AND METHODS: Eight patients with PH-COPD were treated with DHEA (200mg daily orally) for 3 months. The primary end-point was the change in the 6-minute walk test (6-MWT) distance. Secondary end-points included pulmonary hemodynamics, lung function tests and tolerance of treatment. RESULTS: The 6-MWT increased in all cases, from 333m (median [IQR]) (257; 378) to 390m (362; 440) (P<0.05). Mean pulmonary artery pressure decreased from 26mmHg (25; 27) to 21.5mmHg (20; 25) (P<0.05) and pulmonary vascular resistance from 4.2UI (3.5; 4.4) to 2.6UI (2.5; 3.8) (P<0.05). The carbon monoxide diffusing capacity of the lung (DLCO % predicted) increased significantly from 27.4% (20.1; 29.3) to 36.4% (14.6; 39.6) (P<0.05). DHEA treatment did not change respiratory parameters of gas exchange and the 200mg per day of DHEA used was perfectly tolerated with no side effect reported. CONCLUSION: DHEA treatment significantly improves 6-MWT distance, pulmonary hemodynamics and DLCO of patients with PH-COPD, without worsening gas exchange, as do other pharmacological treatments of PH (trial registration NCT00581087).

We report the case of a man who underwent a left-lung transplantation for pulmonary fibrosis and who developed deterioration of his respiratory condition at Day 16 post-operatively, with marked hypoxemia not explained by the usual early respiratory complications of lung transplantation. Contrast-enhanced transthoracic echocardiography identified a patent foramen ovale with massive spontaneous right-to-left shunting. As for the pathogenesis of this right-to-left shunting, we found no evidence supporting an elevation of right-side pressures, with the redirection of the inferior vena cava flow toward the patent foramen ovale being the suspected mechanism. We conclude that delayed reopening of the patent foramen ovale leading to massive right-to-left shunting is a possible complication after lung transplantation.

Angiosarcoma represents 1 to 2% of soft tissue tumors. It originates from endothelial cells of small blood vessels and may affect a variety of organs, including the retroperitoneum, skeletal muscle, subcutis, liver, heart and breast. The outcome of angiosarcoma is poor for those patients in whom aggressive surgery cannot be considered. Chemotherapy, generally consisting of the combination of anthracyclines and ifosfamide, has little, but consistent effect. We report three cases of angiosarcoma in which first-line chemotherapy with adriamycin 40 mg/m2 day 1, ifosfamide 3 g/m2 day 1-2, cisplatin 35 mg/m2 day 1-2 and paclitaxel 175 mg/m2 day 3 led to clinically meaningful responses. The clinical relevance of incorporating paclitaxel in conventional soft tissue chemotherapy schedules in the light of both literature data and our experience is discussed. We emphasize the need for designing trials specifically dedicated to angiosarcomas, as this rare and severe condition may be a target for new antiangiogenic drugs.

BACKGROUND: Pulmonary Langerhans cell histiocytosis (PLCH) is an uncommon interstitial lung disease which can lead to serious respiratory failure. The correlation between high-resolution computed tomography (HRCT) findings and lung function have not been studied in depth. OBJECTIVES: To assess the relationship between HRCT findings and lung function in PLCH. METHODS: Since HRCT abnormalities in PLCH consist mainly of nodular opacities and cystic abnormalities, we determined semiquantitative scores of nodular profusion and cystic extent. We therefore assessed the relationship between HRCT abnormalities on one hand and lung function and gas exchange parameters on the other, in patients with PLCH. RESULTS: In our series of 26 consecutive patients, we found no significant correlation between the score of nodular profusion and lung function or gas exchange parameters. The score of cystic extent showed a quite strong and significant correlation with FEV(1)/FVC (r = -0.62; p = 0.01), but also with PaO(2) (r = -0.69; p = 0.001) and carbon monoxide diffusing capacity (r = -0.60; p < 0.01). Furthermore, the patients with a predominant cystic pattern (n = 7) had the highest grade of dyspnea on exertion (p = 0.004), the lowest FEV(1)/FVC ratio (p = 0.02) and the lowest PaO(2) (p = 0.02) compared to patients with a predominant nodular (n = 12) or a mixed pattern (n = 7). CONCLUSIONS: We conclude that in PLCH, the cystic extent on HRCT, but not the nodular profusion, correlates significantly with lung function abnormalities and impairment of gas exchange.
