Limited-stage disease is confined to an area that is tolerably treated by one radiotherapy area ("port"), but excludes cancers with pleural and pericardial effusions. All other small-cell lung cancers are extensive-stage in this scheme. There has been some drift over time in what this definition means. [citation needed]
Unlike extensive-stage small cell lung cancer, limited-stage small cell lung cancer is potentially curable. [4] In limited small cell lung cancer, the median overall survival time is approximately 12–16 months, with five year survival rate of approximately 26% and long-term survival rate of approximately 4–5%. [19]
In males, researchers suggest that the overall reduction in cancer death rates is due in large part to a reduction in tobacco use over the last half century, estimating that the reduction in lung cancer caused by tobacco smoking accounts for about 40% of the overall reduction in cancer death rates in men and is responsible for preventing at least 146,000 lung cancer deaths in men during the ...
In organic chemistry, a hemiacetal is a functional group the general formula R 1 R 2 C(OH)OR, where R 1, R 2 is a hydrogen atom or an organic substituent. They generally result from the nucleophilic addition of an alcohol (a compound with at least one hydroxy group ) to an aldehyde ( R−CH=O ) or a ketone ( R 2 C=O ) under acidic conditions.
Video-assisted thoracoscopic lung biopsy is the most definitive technique, but transbronchial biopsy has a yield of over 50% and can also be effective. [ 82 ] [ 83 ] The safety of the latter procedure in patients with diffuse cystic disease and the profusion of cystic change that predicts an informative biopsy are incompletely understood, however.
Pfizer’s lung cancer drug Lorbrena can extend life for patients with a rare form of the disease for years longer than other drugs, according to new research published Friday.
Non-small-cell lung cancer (NSCLC), or non-small-cell lung carcinoma, is any type of epithelial lung cancer other than small-cell lung cancer (SCLC). NSCLC accounts for about 85% of all lung cancers. [1] [2] [3] As a class, NSCLCs are relatively insensitive to chemotherapy, compared to small-cell carcinoma.
Pulmonary function: increased residual volume, increased total lung capacity, fixed obstruction, low diffusing capacity of the lung for carbon monoxide that corrects with alveolar volume High-resolution CT scan: diffuse pulmonary nodules 4–10 mm, greater than 20 nodules, mosaic attenuation or air trapping in greater than 50% of the lung
