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

Further study details as provided by National Institute of Cancerología:

Primary Outcome Measures:
  • Response rate, progression-free survival and over-all survival [ Time Frame: 4 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Quantification of CTCs [ Time Frame: 4 years ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA
Peripheral blood samples are collected were the cell pellet are collected from centrifugation, lysed by TRIzol method to get RNA. The RNA is retrotranscribed to cDNA in order to quantify cytokeratin (CK) 19, 18 and carcinoembrionic antigen which are markers of epithelial cells presumambly coming form the tumor.

Estimated Enrollment: 200
Study Start Date: July 2007
Estimated Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Stage IV non small-cell lung cancer patients will be recruited for this protocol

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.

Ages Eligible for Study:   18 Years and older
