PURPOSE: Endobronchial metastasis (EBM) originating from primary cancers outside the lung is rare. External beam radiotherapy is often attempted for control of symptoms with variable effectiveness and retreatment is challenging if symptoms recur. There is limited documentation of high-dose-rate brachytherapy for EBM in the literature. METHODS AND MATERIALS: A prospective database was created from 2006 to 2015. Patients with EBM who received high-dose-rate brachytherapy were included...

174 Background: Local progression after external beam radiation therapy (RT) for lung cancer may result in clinical compromise from bleeding and/or airway obstruction, and additional RT may be precluded by radiation tolerance. High-dose-rate (HDR) endobronchial brachytherapy (EBT) is an effective salvage treatment for airway obstruction and/or bleeding, but requires significant time and resources; planning and treatment are performed bronchoscopically under anesthesia. We sought to reduce procedure and anesthesia time for EBT through template-based planning...

PURPOSE: Small organ subvolume irradiated by a high-dose has been emphasized to be associated with late complication after radiotherapy. Here, we demonstrate a potential use of surface-based, non-rigid registration to investigate how high-dose volume topographically correlates with the location of late radiation morbidity in a case of tracheobronchial radiation stenosis. MATERIAL AND METHODS: An algorithm of point set registration was implemented to handle non-rigid registration between contour points on the organ surfaces...

PURPOSE: The endobronchial brachytherapy (EBBT) is an established treatment method for tumors of the tracheobronchial system, however, little is known about the tolerance dose for organ at risk (OAR) in EBBT. The purpose of this study is to analyze patients with superficial bronchial carcinoma treated with definitive EBBT, and to investigate a relationship between late complications and dose for OAR. MATERIAL AND METHODS: Endobronchial brachytherapy was performed 6 Gy per fraction for three to four fractions with or without external beam radiation therapy (EBRT)...

The majority of patients with lung cancer are diagnosed with clinically advanced disease. Many of these patients have a short life expectancy and are treated with palliative aim. Because of uncontrolled local or recurrent disease, patients may have significant symptoms such as: cough, dyspnea, hemoptysis, obstructive pneumonia, or atelectasis. Brachytherapy is one of the most efficient methods in overcoming difficulties in breathing that is caused by endobronchial obstruction in palliative treatment of bronchus cancer...

PURPOSE: Obstructive symptoms that affect quality of life (QOL) are commonly caused by endobronchial disease in many patients with locally advanced, inoperable lung cancer. High-dose-rate endobronchial brachytherapy (HDREBBT) has been used to palliate these symptoms, yet its role is not well defined in the literature. METHODS AND MATERIALS: Ninety-eight patients with locally advanced, inoperable lung cancer received HDREBBT. They were prospectively followed for survival, QOL, and toxicity endpoints...

Central airway obstruction (CAO) is seen in malignant and nonmalignant airway disorders and can lead to significant morbidity and mortality. Endobronchial ablative therapies are used in conjunction with mechanical debridement to achieve hemostasis and restore airway patency. These therapies can be classified into modalities with immediate or delayed effect. Therapies with immediate effect include heat therapies (such as electrocautery, argon plasma coagulation, and laser) and cryorecanalization using a cryoprobe for tissue extraction...

Radiotherapy is used for inoperable lung cancers, sometimes in association with chemotherapy. Outcomes of conventional radiotherapy are disappointing. New techniques improve adaptation to tumour volume, decrease normal tissue irradiation and lead to increasing tumour dose with the opportunity for improved survival. With intensity-modulated radiation therapy, isodoses can conform to complex volumes. It is widely used and seems to be indicated in locally advanced stages. Its dosimetric improvements have been demonstrated but outcomes are still heterogeneous...

The co-incidence of synchronous intraepithelial neoplasia and early stage invasive lung cancer is not a rare phenomenon. The need for curative treatment and the invasive potential of squamous cell pulmonary carcinoma in situ have been a topic of controversy. Surgical resection still remains the treatment of choice. Varieties of endoscopic techniques such as brachytherapy were developed as an alternative to surgery in selected patients. External beam radiation therapy has been used traditionally in combination with endobronchial brachytherapy in the treatment of roentgenographically occult lung cancer, and can be offered for all patients, but is handicapped, because these tumors are radiographically invisible...

Endobronchial ultrasound (EBUS) in recent years has become a routine diagnostic procedure in bronchology. Linear EBUS shows high diagnostic yield in evaluation of mediastinal lymph nodes. It is mainly used for nodal evaluation in lung cancer, but has also proven to be efficient in diagnostic evaluation of mediastinal masses. This technique has been shown to be complementary to mediastinoscopy. In combination with PET and rapid on site cytology (ROSE), the diagnostic yield of EBUS is significantly higher. Radial EBUS is used for diagnosis of peripheral lung lesions...
