What is the prognosis of Adeno Carcinoma of Lung?
The prognosis depends on the histological type of cancer, the stage of spread and the patient’s performance. The possible treatment includes the chemo therapy, surgery and radio therapy. The 5 year survival rate is only 14 percent and it depends on the stage and treatment. In the case of non small cell lung carcinoma the prognosis depends on the symptoms of lungs , size of tumor, type of cells and the degree of spread with a lymph node involvement or not. It may or may not include the vascular invasion. The patients which cannot be operated their prognosis is badly affected by the poor performance status and a loss of weight which is more than one tenth of total weight. The prognostic factors of small cell lung cancer include the gender, performance status, stage of disease, involvement of the central nervous system at the diagnostic time.
In the case of non small cell lung carcinoma the prognosis is poor. After complete surgical removal of stage 1 A the 5 year survival improves and in the case of stage 1 B the 5 year survival becomes 57 percent. In the case of stage 4 the 5 year survival becomes 1 percent. In the case of small cell lung carcinoma the prognosis is poor. The survival rate is 5 percent and in the later stages of this disease the survival rate is less than 1 percent. In the limited stage disease the survival rate is less than two years and the 5 year survival rate is 20 percent. As per the data given by the national cancer institute the median age of incidence of lung cancer is 70 and the median age of incidence of lung cancer is 71.
