RESUMO
BACKGROUND: Because of limitations in previous randomised controlled trials and observational studies, the effectiveness of immediate video-assisted thoracoscopic surgery (VATS) for patients with empyema in real-world settings remains unclear. OBJECTIVE: This study aimed to evaluate whether immediate VATS improves clinical outcomes in patients with empyema. METHODS: This multicentre retrospective cohort study included 744 patients with physician-diagnosed empyema from six hospitals between 2006 and 2021. The exposure was VATS performed within 3 days of empyema diagnosis, the primary outcome was 30-day mortality, and secondary outcomes were 90-day mortality, length of hospital stay, and time from diagnosis to discharge. We used propensity score weighting to account for potential confounders. For outcome analyses, we used logistic regression for mortality outcomes and gamma regression for the number of days. RESULTS: Among the 744 patients, 53 (7.1%) underwent VATS within 3 days, and 691 (92.9%) initially received conservative treatment. After propensity score weighting, the differences in 30- and 90-day mortalities between the immediate VATS and initial conservative treatment groups were 1.18% (95% confidence interval [CI], -10.7 to 13.0%) and -0.08% (95% CI, -10.3 to 10.2%), respectively. The differences in length of hospital stay and time from diagnosis to discharge were -3.22 (95% CI, -6.19 to -0.25 days) and -5.04 days (95% CI, -8.19 to -1.90 days), respectively. CONCLUSIONS: Our real-world study showed that immediate VATS reduced the length of hospital stay and the time from diagnosis to discharge. Considering the small sample and differences in protocols between countries, further large-scale studies are warranted.

Background: Video-assisted thoracoscopic surgery is a widely recommended treatment for empyema in advanced stages. However, only a few studies have evaluated prognostic factors among patients with empyema who underwent video-assisted thoracoscopic surgery. Furthermore, no studies have evaluated predictors of direct discharge home. Patients and Methods: This multicenter retrospective cohort study included 161 patients with empyema who underwent video-assisted thoracoscopic surgery in five acute-care hospitals. The primary outcome was the probability of direct discharge home. The secondary outcome was the length of hospital stay after surgery. We broadly assessed pre-operative factors and performed univariable logistic regression for the direct discharge home and univariable gamma regression for the length of hospital stay after surgery. Results: Of the 161 included patients, 74.5% were directly discharged home. Age (>70 years; -24.3%); altered mental status (-33.4%); blood urea nitrogen (>22.4 mg/dL; -19.4%); and pleural pH (<7.2; -17.6%) were associated with high probabilities of not being directly discharged home. Fever (15.2%) and albumin (> 2.7 g/dL; 20.2%) were associated with high probabilities of being directly discharged home. The median length of stay after surgery was 19 days. Age (>70 years; 6.2 days); altered mental status (5.6 days); purulence (2.7 days); pleural thickness (>2 cm; 5.1 days); bronchial fistula (14.6 days); albumin (>2.7 g/dL; 3.1 days); and C-reactive protein (>20 mg/dL; 3.6 days) were associated with a longer post-operation hospital stay. Conclusions: Physicians should consider using these prognostic factors to predict non-direct discharge to the home for patients with empyema.

Rationale: Chest computed tomography is performed in patients with empyema for various reasons. However, its predictive ability for patient outcomes in empyema has not been evaluated. Objectives: To evaluate the predictive ability of computed tomography findings (pleural thickness, loculation, interlobar pleural effusion, lung abscess, and bronchopleural fistula) for 90-day mortality in empyema. Methods: This multicenter retrospective cohort study was conducted across six acute care hospitals in Japan. We included patients with confirmed empyema diagnoses who underwent chest computed tomography within 7 days of diagnosis. Imaging findings were defined as pleural thickness, loculation, interlobar pleural effusion, lung abscess, or bronchopleural fistula. One radiologist interpreted the computed tomography scans without patient information. The primary outcome was 90-day mortality. We calculated the differences in 90-day mortality between the presence and absence of each computed tomography finding using logistic regression with or without adjustment for early thoracic surgery. Results: A total of 711 patients were included in our study. Thoracic surgery was performed in 27% of patients, and the 90-day mortality rate was 10%. The differences (95% confidence intervals) in 90-day mortality without and with adjustment for early thoracic surgery were as follows: pleural thickness, 3.09% (-1.35% to 7.54%) and 2.70% (-1.80% to 7.20%); loculation, -4.01% (-8.61% to 0.60%) and -3.80% (-8.41% to 0.81%); interlobar pleural effusion, -9.15% (-14.58% to -3.72%) and -8.96% (-14.39% to -3.53%); lung abscess, 7.04% (-1.16% to 15.2%) and 6.86% (-1.34% to 15.05%); and bronchopleural fistula, 13.80% (7.66% to 19.94%) and 13.63% (7.50% to 19.77%), respectively. Conclusions: Although interlobar pleural effusion predicted lower 90-day mortality regardless of early thoracic surgery, the presence of bronchopleural fistula predicted higher 90-day mortality with empyema. Our results warrant further validation.

OBJECTIVES: Afatinib is an effective treatment in patients who have epidermal growth factor receptor (EGFR) mutation-positive non-small-cell lung cancer (NSCLC), but its toxicities often require dose adjustment. Exploratory analyses of previous trials have suggested that reducing the dose of afatinib can decrease treatment-related adverse events without negatively affecting effectiveness. The aim of this study was to assess the efficacy and safety of low starting dose of afatinib with dose modification according to its toxicity in patients with EGFR mutation-positive NSCLC. MATERIALS AND METHODS: This study was a multicenter, single-arm, open-label phase II trial. Treatment-naïve patients with advanced NSCLC positive for common EGFR mutations received afatinib starting in a dose of 20 mg/day. If tolerated, the dose was increased in 10-mg increments up to 50 mg/day. The primary endpoint was progression-free survival (PFS). RESULTS: From February 2015 through March 2016, 46 patients were enrolled. The median age was 73 years (range, 43-86), and 35 patients (72%) were women.EGFR mutation subtypes included exon 19 deletion (54%) and Leu858Arg point mutation (46%). Most patients had a performance status of 0 or 1 (91%) and a histological diagnosis of adenocarcinoma (98%). As of the data cut-off date of June 2017, the median follow-up was 18.9 months. The median PFS was 15.2 months (95% CI: 13.2-not estimable). The 1-year overall survival rate was 95.6% (95% CI: 89.7%-100%). The objective response rate was 81.8% (95% CI, 81.3%-98.6%). Adverse events of grade 3 or higher occurred in 14 patients (30.4%) and included rash/acne in 4 patients (8.7%), paronychia in 4 patients (8.7%), diarrhea in 2 patients (4.3%). There was no treatment-related death. CONCLUSIONS: Low starting dose of afatinib therapy showed promising clinical efficacy and good tolerability. Further investigations are warranted.

BACKGROUND: Nanoparticle albumin-bound paclitaxel (nab-PTX), which avoids toxicities associated with a vehicle used in solvent-based PTX, has already shown safety and efficacy in patients with non-small cell lung cancer (NSCLC). METHODS: A phase II study was performed to assess the safety and efficacy of nab-PTX monotherapy as second-line chemotherapy after cytotoxic anticancer drugs for previously treated advanced NSCLC. Thirty-two patients with advanced NSCLC who had previously undergone 1 regimen of cytotoxic anticancer drugs were enrolled. Nab-PTX was administered intravenously at a dose of 100âmg/m on days 1, 8, and 15 of a 28-day cycle. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and toxicity profile were evaluated. RESULTS: The ORR was 28.1%, the DCR was 71.9%, median PFS was 3.9 months (95% confidence interval [CI] 2.7-5.1 months), and median OS was 10.9 months (95% CI 9.5-12.3 months). The mean relative dose intensity of nab-PTX was 77%. Grade 3 or 4 neutropenia, and grade 3 febrile neutropenia were observed in 11 and 1 of 32 patients, respectively. As nonhematologic toxicities, grade 3 peripheral sensory neuropathy and pneumonitis were each observed in 2 of 32 patients. CONCLUSION: Nab-PTX is an active and well-tolerated regimen in patients with previously treated NSCLC.
