GTV and CTV in lung cancer

Dosimetric Consequences of Uncertainties in High-Risk CTV (HR CTV) Delineation for Cervical Cancer Brachytherapy

Role of Adenosine receptor in lung cancer

Summary: Adenosine through adenosine receptor have a crucial role in biology of lung cancer. Recent study indicated adenosine receptors have a crucial role in various aspect of lung cancer from cell growth and metastasis to modulation of apoptosis and it could be considered as a potential candidate for treatment of the lung cancer.

Delineation in thoracic oncology: a prospective study of the effect of training on contour variability and dosimetric consequences

INTRODUCTION As part of French residents' radiotherapy training, delineation workstations were available at a national teaching course. We report a prospective comparative study of a non small cell lung cancer (NSCLC) case delineated by 120 residents before and after a radioanatomy/radiotherapy lecture. MATERIALS AND METHODS The case of a patient with right upper lobe non small cell lung canc...

Pulmonary Actinomycosis Mimicking Lung Cancer

Herein, we reported on a case of solid type of pulmonary actinomycosis in a 10-year-old boy. He had productive cough for 40 days. Bronchoscopy was normal. Cmputed tomography revealed a solid large mass in the upper lobe of his left lung with mimicking malignant leisions. He was referred for surgery and underwent left upper lobectomy. Macroscopically, the specimen measured 13×9×5 cm and was crea...

Recommendations from Gynaecological (GYN) GEC-ESTRO Working Group (I): concepts and terms in 3D image based 3D treatment planning in cervix cancer brachytherapy with emphasis on MRI assessment of GTV and CTV.

BACKGROUND AND PURPOSE Brachytherapy (BT) plays a crucial role in the management of invasive cervix cancer from stage I to IV. Intracavitary techniques are based on afterloading devices, with different types of applicators. CT and/or MRI compatible applicators allow a sectional image based approach with a better assessment of gross tumour volume (GTV) and definition and delineation of target vo...
