RESULTS
The NSCLC samples were classified by an experienced
pathologist into 50.1% (n = 276) adenocarcinoma
and 49.9% (n = 275) other histological types. Distribution
by stage was as follow: 38 patients were diagnosed with
stage IIIB and 513 were stage IV. There were 338 smokers
(61.3%) and 213 were non smokers (38.7%). The risk of
having lung cancer for smokers increased with the number
of cigarettes smoked per day or duration of smoking [10].
The clinical characteristics of the patients are shown in
Table 1.
Mutational status was determined according to the
manufacturer’s protocol. All samples analyzed had an internal
control CT value in the reference range 23-30, 69.
Positive amplification for EGFR mutational assay was considered
in the case of CT value within the range of 15-40.
The ΔCT value for each mutation sample showing positive
amplification was calculated by the formula: ΔCT = mutation
CT-control CT and compared to the reference provided
by the manufacturer (Figure 1). The EGFR gene mutations were found in 10.0% of the NSCLC samples (n = 55) using
the therascreen EGFR assay (Qiagen Ltd.) (Table 2).
