Alveolar cell carcinoma of the lung represents that group of primary pulmonary tumors, which originate in the lining cells of the alveoli, as sug- gested by their distinctive microscopic picture, distinguishing them, morphologically, from the usual form of bronchogenic carcinoma.
Which type of bronchogenic carcinoma has worse prognosis?
In general, patients with squamous cell carcinoma have the best prognosis, those with adenocarcinoma and undifferentiated large cell carcinoma have an intermediate prognosis, and those with small cell carcinoma have the worst prognosis.
Which is worse adenocarcinoma or squamous cell carcinoma?
In subgroup analysis, patients with adenocarcinoma had significantly worse OS and DFS compared with patients with SCC, regardless of treatment with radiotherapy alone or CCRT.
What are alveolar cells?
The alveolar epithelium comprises two main cell types: the alveolar type I and alveolar type II cell. The type I cell is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and relatively devoid of organelles; these plates represent the gas exchange surface in the alveolus.
What is alveolar septa?
The alveolar septum is also called the interalveolar septum or the interradicular septum, and is one of the very thin plates of bone that separates the alveoli or tooth sockets in the teeth from one another in both the maxillary alveolar ridge and the lower alveolar ridge.
What is the survival rate of bronchogenic carcinoma?
Prognosis. The overall five-year survival rate for bronchogenic carcinoma is about 18.6%. 1 Prognosis varies based on the type and stage of lung cancer, with survival rates being much better when the disease is diagnosed in the earlier stages.
How long does it take for adenocarcinoma to spread?
It takes about three to six months for most lung cancers to double their size. Therefore, it could take several years for a typical lung cancer to reach a size at which it could be diagnosed on a chest X-ray.
What is the survival rate for bronchioloalveolar carcinoma?
Survival rates vary depending on the stage of cancer, but generally speaking, the survival rate for bronchioloalveolar carcinoma is much better than other forms of non-small cell lung cancer when caught early. The survival rate for later stages of the disease vary and are dependent on a number of varying factors.
What is the survival rate for BAC lung cancer?
In general, the survival rate is significantly better for BAC than for other forms of non-small cell lung cancer, especially when it is caught early and only one tumor is present. In one study, those who were diagnosed with BAC and had tumors less than 3 centimeters in diameter, had a 5-year survival rate of 100 percent with surgery.
What is the survival rate for non-small cell lung cancer?
In general, the survival rate is significantly better for BAC than for other forms of non-small cell lung cancer, especially when it is caught early and only one tumor is present. In one study, those who were diagnosed with BAC and had tumors less than 3 centimeters in diameter, had a 5-year survival rate of 100 percent with surgery. 5
What is bronchioloalveolar carcinoma of the lungs (BAC)?
Bronchioloalveolar carcinoma of the lungs (BAC), as noted above, has now been reclassified as a form of lung cancer.
