CT-guided biopsy of lung lesions: defining the best needle option for a specifi...

OBJECTIVES: To evaluate the performance of fine and cutting needles in computed tomography guided-biopsy of lung lesions suspicious for malignancy and to determine which technique is the best option for a specific diagnosis. METHODS: This retrospective study reviewed the data from 362 (71.6%) patients who underwent fine-needle aspiration biopsy and from 97 (19.7%) patients who underwent cutting-needle biopsy be...

Improving CT-guided transthoracic biopsy of mediastinal lesions by diffusion-we...

OBJECTIVES: To evaluate the preliminary results obtained using diffusion-weighted magnetic resonance imaging and the apparent diffusion coefficient for planning computed tomography-guided biopsies of selected mediastinal lesions. METHODS: Eight patients with mediastinal lesions suspicious for malignancy were referred for computed tomography-guided biopsy. Diffusion-weighted magnetic resonance imaging and appare...

Predictive complication factors for ct-guided fine needle aspiration biopsy of ...

OBJECTIVE: Distinct aspects can influence the complication rates of computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions. The purpose of the current study is to determine the influence of radiological techniques and clinical characteristics in predicting complications from this procedure. SUBJECTS AND METHODS: A retrospective study was developed involving 340 patients who were s...

Pulmonary metastasectomy from soft tissue sarcomas

INTRODUCTION: Isolated pulmonary metastases from soft tissue sarcomas occur in 20-50% of these(the issue is about metastases, not lung cancer )patients, and 70% of these patients will present disease limited only to the lungs. Surgical resection is well accepted as a standard approach to treat metastases from soft tissue sarcomas isolated in the lungs, and many studies investigating this technique have reported...

Metastatic non-small cell lung cancer in Brazil: treatment heterogeneity in rou...

ABSTRACT: Lung cancer is one of the main causes of cancer related deaths. Approximately three quarters of these tumors are non-small cell carcinomas. When diagnosed the majority of patients show the disease locally advanced or metastatic. The chemotherapy is the chosen therapy for patients with advanced lung cancer. The majority of published studies with chemotherapy are performed in academic centers under a st...
