Marketing direction still lacking. Don't believe they have ever advertised in CAP (College of American Pathology) journal. Leading Company in this space, bioTheranostics, places an advertisement every month.
bioTheranostics has a test, CTID - Cancer Type ID, that distinguishes specifically between squamous and non-squamous carcinoma of the Lung. If you check the literature, I believe you will find the Rosetta test only distinguishes Squamous Cell Carcinoma of the Lung from Squamous Cell H&N from Squamous Cell of the Esophagus and that all three of these require different systemic chemotherapy.
