Results of Bronchial Artery Embolization for the Treatment of Hemoptysis Caused by Neoplasm

PURPOSEnTo describe experience with bronchial artery embolization (BAE) in a cohort of patients with cancer.nnnMATERIALS AND METHODSnAll consecutive patients with cancer and at least one episode of hemoptysis that required BAE during a 14-year period were included in this observational retrospective review. The endpoints of the study were immediate success, recurrence of hemoptysis, mortality resulting from hemoptysis, and all-cause mortality.nnnRESULTSnImmediate control of bleeding was achieved in 31 of 40 patients (77.5%). Recurrence requiring BAE occurred in eight patients (20%). Cumulative hemoptysis control rate was 0.90 (95% confidence interval [CI], 0.80-1.0) at 1 month and 0.65 (95% CI, 0.44-0.86) at 6 months. Probability of survival was 0.75 (95% CI, 0.62-0.88) at 1 month, 0.42 (95% CI, 0.27-0.57) at 6 months, 0.36 (95% CI, 0.21-0.51) at 12 months, and 0.08 (95% CI, 0.0-0.18) at 3 years.nnnCONCLUSIONSnBAE is an effective and safe technique in the treatment of hemoptysis in patients with cancer. Nevertheless, mortality resulting from hemoptysis and recurrence rate are high among these patients secondary to progression of the underlying disease.

Transbronchial and transesophageal fine-needle aspiration using a single ultrasound bronchoscope in the diagnosis of locoregional recurrence of surgically-treated lung cancer

BackgroundThe present study sought to evaluate the usefulness of EBUS-TBNA in the diagnosis of locoregional recurrence of lung cancer in a cohort of lung cancer patients who were previously treated surgically, and describe our initial experience of EUS-B-FNA in this clinical scenario.MethodsWe retrospectively studied the clinical records of all patients with a previous surgically-treated lung cancer who were referred to our bronchoscopy unit after suspicion of locoregional recurrence. The diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and overall accuracy of EBUS-TBNA for the diagnosis of locoregional recurrence were evaluated.ResultsSeventy-three patients were included. EBUS-TBNA confirmed malignancy in 40 patients: 34 confirmed to have locoregional recurrence, six had metachronous tumours. Of the 33 patients with non-malignant EBUS-TBNA; 2 had specific non-malignant diseases, 26 underwent radiological follow up and 5 patients underwent surgery. Of the 26 patients who had radiological follow up; 18 remained stable, three presented thoracic radiological progression and 5 presented extrathoracic progression. Of the 5 patients who underwent surgery; 3 had metachronous tumours, one confirmed to be a true negative and one presented nodal invasion. Seven patients underwent EUS-B-FNA, four of them confirmed to have recurrence. The sensitivity, specificity, NPV, PPV and overall accuracy of EBUS-TBNA for the diagnosis of locoregional recurrence were 80.9, 100, 69.2, 100 and 86.6% respectively.ConclusionsEBUS-TBNA is an accurate procedure for the diagnosis of locoregional recurrence of surgically-treated lung cancer. EUS-B-FNA combined with EBUS-TBNA broads the diagnostic yield of EBUS-TBNA alone.

Cáncer de pulmón en pacientes con combinación de fibrosis pulmonar y enfisema y fibrosis pulmonar idiopática. Estudio descriptivo en una serie española

INTRODUCTIONnInformation on the association of lung cancer (LC) and combined pulmonary fibrosis and emphysema (CPFE) is limited and derived almost exclusively from series in Asian populations. The main objective of the study was to assess the impact of LC on survival in CPFE patients and in patients with idiopathic pulmonary fibrosis (IPF).nnnMETHODSnA retrospective study was performed with data from patients with CFPE and IPF diagnosed in our hospital over a period of 5 years.nnnRESULTSnSixty-six patients were included, 29 with CPFE and 37 with IPF. Nine had a diagnosis of LC (6 with CPFE and 3 with IPF). Six patients (67%) received palliative treatment even though 3 of them were diagnosed atstage i-ii. Overall mortality did not differ significantly between groups; however, in patients with LC, survival was significantly lower compared to those without LC (P=.044). The most frequent cause of death was respiratory failure secondary to pulmonary fibrosis exacerbation (44%). In a multivariate analysis, the odds ratio of death among patients with LC compared to patients without LC was 6.20 (P=.037, 95% confidence interval: 1.11 to 34.48).nnnCONCLUSIONSnLung cancer reduces survival in both entities. The diagnostic and therapeutic management of LC is hampered by the increased risk of complications after any treatment modality, even after palliative treatment.

Factores predictores de recanalización arterial en pacientes con hemoptisis amenazante que requieren embolización arterial

INTRODUCTIONnArtery embolization (AE) is a safe and useful procedure in the management of massive hemoptysis. The objective of our study was to describe the experience of AE in a tertiary referral center, to characterize angiographic findings at the time of recurrence, and to analyze factors associated with these findings.nnnMATERIAL AND METHODSnObservational retrospective study of patients presenting with life-threatening hemoptysis. All consecutive patients with at least one episode of hemoptysis that required AE during a 13-year period were included. The effects of i)time to recurrence; ii)use of coils, and iii)number of arteries embolized on the likelihood that the recurrence was secondary to recanalization were assessed.nnnRESULTSnOne hundred seventy-six patients were included in the study. Twenty-two patients (12.5%) died due to hemoptysis. Probability of recurrence-free survival at one month was 0.91 (95%CI: 0.87 to 0.95), at 12months was 0.85 (95%CI: 0.79 to 0.91), and after 3 years was 0.75 (95%CI: 0.66 to 0.83). A longer time to recurrence was associated with a higher probability that the hemorrhage affected the same artery (estimate=0.0157, z-value=2.41, p-value=0.016).nnnCONCLUSIONnAE is a safe and useful technique in the management of massive and recurrent hemoptysis. Nevertheless, recurrence after embolization is not uncommon. Recurring hemoptysis due to recanalization is related to time to recurrence, but not to the use of coils or number of arteries embolized.

Systematic Compared With Targeted Staging With Endobronchial Ultrasound in Patients With Lung Cancer

BACKGROUNDnTo evaluate the accuracy of systematic mediastinal staging by endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) (sampling of all visible nodes measuring ≥5 mm from stations N3 to N1 regardless of their positron emission tomography/computed tomography [PET/CT] features) and compare this staging approach with targeted EBUS-TBNA staging (sampling only 18F-fluorodeoxyglucose [FDG]-avid nodes) in patients with N2 non-small cell lung cancer on PET/CT.nnnMETHODSnRetrospective study of 107 patients who underwent systematic EBUS-TBNA mediastinal staging. The results were compared with those of a hypothetical scenario where only FDG-avid nodes on PET/CT would be sampled.nnnRESULTSnSystematic EBUS-TBNA sampling demonstrated N3 disease in 3 patients, N2 disease in 60 (42xa0single-station or N2a, 18 multiple-station or N2b) and N0/N1 disease in 44. Of these 44, 7 underwent mediastinoscopy, which did not show mediastinal disease; 6 of the 7 proceeded to lung resection, which also showed no mediastinal disease. Thirty-four N0/N1 patients after EBUS-TBNA underwent lung resection directly: N0/N1 was found in 30 and N2 in 4 (1 N2b with a PET/CT showing N2a disease, 3 N2a). Sensitivity, specificity, negative predictive value, positive predictive value, and overall accuracy of systematic EBUS-TBNA were 94%, 100%, 90%, 100% and 96%, respectively. Compared with targeted EBUS-TBNA, systematic EBUS-TBNA sampling provided additional important clinical information in 14 cases (13%): 3 N3 cases would have passed unnoticed, and 11 N2b cases would have been staged as N2a.nnnCONCLUSIONSnIn clinical practice, systematic sampling of the mediastinum by EBUS-TBNA, regardless of PET/CT features, is to be recommended over targeted sampling.
