Carcinoid Lung Tumor (cont.)


The outlook of carcinoid lung tumors depends on the size of the tumor, the type of tumor (typical or atypical), and whether the tumor has spread to the lymph nodes at the time of diagnosis.

Because carcinoid lung tumors grow and spread slowly, they often are discovered at an early stage. The outlook for people with early-stage typical carcinoid lung tumors is usually very good. Atypical carcinoid lung tumor is more likely to have spread to nearby tissues or lymph nodes at the time of diagnosis.

Survival rates are lower for people with atypical carcinoid tumors and carcinoid tumors that have spread to other parts of the body.

Carcinoid lung tumors generally have a better outlook than other forms of lung cancer. Persons with carcinoid lung tumors have an overall 5-year survival rate of 78%-95% and a 10-year survival rate of 77%-90%.

Persons with typical carcinoid tumors have been found to have a much better outlook than those with the atypical variety. Atypical carcinoid tumors have been associated with a 5-year survival rate of 40%-60% and a 10-year survival rate of 31%-60%.

Regardless of the type of carcinoid lung tumor, the presence of lymph node metastases at the time of resection has a significant effect on outlook.

The presence of carcinoid syndrome in the absence of spread to the lymph node or other tissues does not seem to affect the outlook adversely.
