Observational Model: Cohort, Time Perspective: Prospective
Overall Status
The purpose of the study is to evaluate the association between the number of circulating tumor cells and response to treatment in non small-cell lung cancer patients
Detailed Description
In spite of technological advantages in diagnosis and treatment, lung cancer remains one of the most deadly malignant neoplasias. Moreover, there are no markers for monitoring response to treatment. The objective of the study is to associate the number of circulating tumor cells (CTC) before and after treatment and correlate it with tumor response rate, progression-free survival and overall survival.
