Endobronchial Treatment for Bronchial Carcinoid: Patient Selection and Predictors of Outcome.

ABSTRACT: BACKGROUND:Traditionally, surgical resection is the preferred treatment for typical carcinoids and atypical carcinoids located in the lungs. Recently however, several studies have shown excellent long-term outcome after endobronchial treatment of carcinoid tumors located in the central airways. This study investigates clinical and radiological features as predictors of successful endobronchial treatment in patients with a bronchial carcinoid tumor. OBJECTIVES:To identify clinical and radiological features predictive of successful endobronchial treatment in patients with bronchial carcinoid. METHODS:This analysis was performed in a cohort of patients with typical and atypical bronchial carcinoid referred for endobronchial treatment. Several patient characteristics, radiological features, and histological grade (typical or atypical carcinoid) were tested as predictors of successful endobronchial treatment. RESULTS:One hundred and twenty-five patients with a diagnosis of bronchial carcinoid underwent endobronchial treatment. On multivariate analysis, a tumor diameter <15 mm (odds ratio 0.09; 95% confidence interval 0.02-0.5; p = <0.01) and purely intraluminal growth on computer tomography (CT scan) (odds ratio, 9.1; 95% confidence interval 1.8-45.8; p = <0.01) were predictive of radical endobronchial treatment. The success rate for intraluminal tumors with a diameter <20 mm was 72%. CONCLUSIONS:Purely intraluminal disease and tumor diameter on CT scan seem to be independent predictors for successful endobronchial treatment in patients with bronchial carcinoid. Based on these data, patients with purely intraluminal carcinoid tumors with a diameter <20 mm on CT scan are good candidates for endobronchial treatment, regardless of histological grade. In contrast, all patients with a tumor diameter ?20 mm should be directly referred for surgery.

Project description:BackgroundCuratively treated bronchial carcinoid tumors have a relatively low metastatic potential. Gradation into typical (TC) and atypical carcinoid (AC) is limited in terms of prognostic value, resulting in yearly follow-up of all patients. We examined the additional prognostic value of novel immunohistochemical (IHC) markers to current gradation of carcinoids.MethodsA retrospective single-institution cohort study was performed on 171 patients with pathologically diagnosed bronchial carcinoid (median follow-up: 66 months). The risk of developing distant metastases based on histopathological characteristics (Ki-67, p16, Rb, OTP, CD44, and tumor diameter) was evaluated using multivariate regression analysis and the Kaplan-Meier method.ResultsOf 171 patients, seven (4%) had disseminated disease at presentation, and 164 (96%) received curative-intent treatment with either endobronchial treatment (EBT) (n = 61, 36%) or surgery (n = 103, 60%). Among the 164 patients, 13 developed metastases at follow-up of 81 months (IQR 45-162). Univariate analysis showed that Ki-67, mitotic index, OTP, CD44, and tumor diameter were associated with development of distant metastases. Multivariate analysis showed that mitotic count, Ki-67, and OTP were independent risk factors for development of distant metastases. Using a 5% cutoff for Ki-67, Kaplan-Meier analysis showed that the risk of distant metastasis development was significantly associated with the number of risk predictors (AC, Ki-67 ≥ 5%, and loss of OTP or CD44) (p < 0.0001). Six out of seven patients (86%) with all three positive risk factors developed distant metastasis.ConclusionsMitotic count, proliferation index, and OTP IHC were independent predictors of dissemination at follow-up. In addition to the widely used carcinoid classification, a comprehensive analysis of histopathological variables including Ki-67, OTP, and CD44 could assist in the determination of distant metastasis risks of bronchial carcinoids.

Project description:Previous studies have shown that patients' anxiety and dissatisfaction are predictors for increased postoperative pain and reduced efficacy of pain treatment. However, it remains to be shown whether patient anxiety and concern are predictors for the perceived quality of treatment and patient reported outcome (PRO).The aim of this study is to investigate whether there is a correlation between preoperative anxiety and concern, and the perceived quality of postoperative treatment and outcome. The hypothesis is that anxious and concerned patients are less satisfied with treatment and have a poorer outcome.This study is designed as a prospective follow-up study and has the aim of investigating the correlation between patient anxiety and concern, patients' perceived quality of treatment and outcome. This correlation will be detected using five questionnaires: CMD-SQ (Common Mental Disorders Screening Questionnaire), EuroQol 5 Dimensions (EQ-5D), Short form 12 (SF-12), "What is your evaluation of the patient progress in the Department of Orthopaedic Surgery?" (HVOK), Questionnaire for patients who have had hip surgery (RCS) and Oxford Hip Score (OHS) or Oxford Shoulder Score (OSS). The patients will complete the above mentioned questionnaires preoperatively in the outpatient department, and postoperatively just before discharge from the inpatient department, and 12 and 52 weeks after the operation. The study includes a reliability test of CMD-SQ regarding this specific population and tested by means of a Kappa. A total of 500 hip- and shoulder-patients will be included from October 2010 till October 2011.If a correlation between patient anxiety and concern, patients' perceived quality of treatment and patient reported outcome is found, it will be recommended to screen all hip- and shoulder-patients for anxiety and concern preoperatively. Besides, it would be relevant to carry out investigations of possible interventions towards anxious and concerned patients.Current Controlled Trials: NCT01205295.
