Abstract

This application provides assays and methods for diagnosis and prognosis of lung cancer using expression analysis of one or more genes from a biological sample comprising nasal epithelial cells. The assays and methods are non-invasive and accurately detect the presence or absence of lung cancer relative to, for example, more invasive techniques, such as bronchoscopy. Similarly, the assays and methods described provide non-invasive ways of accurately identifying the smoking history of a subject.

Claims (30)

1 . A method, comprising:

(a) performing a diagnostic procedure on a subject to determine a risk of malignancy for a subject for having or developing lung cancer, wherein said diagnostic procedure comprises a computer-aided tomography, a chest X-ray, or a bronchoscopy, and wherein said diagnostic procedure provides an indeterminate result for lung cancer;

(b) responsive to said indeterminate result for lung cancer, obtaining a nasal epithelial sample of said subject;

(c) generating a data set comprising (i) one or more genomic features in said nasal epithelial sample of said subject and (ii) one or more clinical features of said subject,

wherein generating said data set comprises sequencing ribonucleic acid (RNA) molecules derived from said nasal epithelial sample to determine said one or more genomic features,

wherein said one or more genomic features comprise genomic markers that are differentially expressed in nasal epithelium of subjects with lung cancer as compared to subjects without lung cancer;

(d) in a programmed computer, using a classifier to process said data set comprising said one or more genomic features and said one or more clinical features, to determine whether said subject has an increased risk of having or developing said lung cancer; and

(e) responsive to said determining in (d), administering to said subject a therapeutic intervention for lung cancer, wherein said therapeutic intervention comprises chemotherapy, radiation therapy, immunotherapy, surgical resection, or a combination thereof.

2 . The method of claim 1 , wherein said one or more genomic features comprise a genomic marker indicative of smoking status.

3 . The method of claim 2 , wherein said genomic marker indicative of smoking status is determined based at least in part on expression products of genes differentially expressed in current smokers and former smokers.

4 . The method of claim 1 , wherein said one or more genomic features comprise a genomic marker indicative of time since quitting smoking.

5 . The method of claim 1 , wherein said subject has lung nodules that are inconclusive for lung cancer as determined by computer aided tomography scan or bronchoscopy.

6 . The method of claim 1 , wherein said nasal epithelial sample comprises nasal epithelial cells.

7 . The method of claim 1 , further comprising obtaining said nasal epithelial sample from said subject by brushing.

8 . The method of claim 1 , wherein said subject has a lung nodule or lesion greater than 3 centimeters.

9 . The method of claim 1 , wherein said subject has a lung nodule or lesion less than 3 centimeters.

10 . The method of claim 1 , wherein said one or more clinical features are selected from the group consisting of: age, nodule or lesion size, nodule or lesion location, and any combination thereof.

11 . The method of claim 1 , wherein said one or more genomic features comprise gene expression products of said nasal epithelial sample obtained from said subject.

12 . The method of claim 1 , wherein said classifier uses a trained algorithm.

13 . The method of claim 12 , wherein said trained algorithm has been trained with a training data set comprising sequence information derived from transcripts of bronchial epithelial cells.

14 . The method of claim 12 , wherein said trained algorithm has been trained with a training data set comprising sequence information derived from transcripts of nasal epithelial cells.

15 . The method of claim 1 , wherein said data set further comprises a ribonucleic acid (RNA) integrity number.

16 . The method of claim 1 , wherein said lung cancer is selected from the group consisting of adenocarcinoma, squamous cell carcinoma, small cell cancer, and non-small cell cancer.

17 . The method of claim 1 , wherein said diagnostic procedure comprises said computer-aided tomography.

18 . The method of claim 1 , wherein said diagnostic procedure comprises said chest X-ray.

19 . The method of claim 1 , wherein said diagnostic procedure comprises said bronchoscopy.

20 . The method of claim 1 , wherein said therapeutic intervention comprises said chemotherapy.

21 . The method of claim 1 , wherein said therapeutic intervention comprises said radiation therapy.

22 . The method of claim 1 , wherein said therapeutic intervention comprises said immunotherapy.

23 . The method of claim 1 , wherein said therapeutic intervention comprises said surgical resection.
