DMTX invaScan™, a novel and accurate tool for the diagnosis and prognosis of invasive tumors


DMTX invaScan is an immunohistochemistry assay, based on a monoclonal antibody that specifically detects collagen XI-α1 in tissue biopsy samples from patients with infiltrating carcinomas, optimized for being used in the most common automated staining platforms.

Technical benefits

Oncomatryx has developed a monoclonal antibody that is highly specific for human proCOL11A1. It does not cross-react with other similar collagens such as COL5A1 and it clearly marks peritumoral stromal cells.

DMTX invaScan specifically detects COL11A1 in different tissue samples, with high sensitivity, specificity and reproducibility. A very clear intense intracellular staining of peritumoral fibroblasts, allows an easy interpretation of results, with no need for quantitation of the stain, nor complicated analysis of the morphological features of the positive cells. DMTX invaScan is optimized for its use in the common immunohistochemistry automated platforms in Pathology labs, allowing an user-friendly introduction in clinical routine.

The expression of COL11A1 in peritumoral stromal fibroblasts instead of tumor cells, enables the diagnosis of different types of tumors. Multicenter clinical validations in Europe and USA have already proven its clinical usefulness for breast, ovary, pancreas, head and neck, bladder and colon cancer.

Clinical benefits

DMTX invaScan facilitates diagnosis and prognosis of tumor invasiveness in small biopsy samples, aiding the selection of the most suitable treatment for each patient.

Clinical indications

DMTX InvaScan facilitates diagnosis and prognosis of different invasive carcinomas:


PANCREATIC CANCER: COL11A1 was found in the desmoplastic stroma of pancreatic ductal adenocarcinomas, distinguishing them from chronic pancreatitis and ampullary carcinomas (García-Pravia et al. 2013. PloS ONE 8(10): 1-13).

COLON CANCER: COL11A1 was detected in the stroma of colonic polyps with malignant component, distinguishing them from benign polyps (Galván JA. et al. BMC Cancer 2014; 14:867).

BREAST CANCER: COL11A1 was found in the desmoplastic stroma of infiltrating carcinomas, distinguishing them from benign inflamatory and sclerosing complex lesions. DMTX invaScan facilitates diagnosis of infiltrating breast tumors in biopsy core samples with high sensitivity and specificity (Fuentes-Martínez N. et al. Histol Histopathol. 2015; 30(1):87-93).

DMTX invaScan has shown higher sensitivity than myoepithelial markers (p63 and calponin) in detecting tumor invasion in core needle biopsies, diagnosing 25/25 infiltrating tumors that were misdiagnosed by current biomarkers (Freire et al. 2014. Pathol Res Pract. 2014; 210(12): 879-884).

BREAST PAPILLOMAS: Prognosis of recurrence and malignant recurrence of breast non-malignant papillary lesions. It has been validated by means of IHC on core needle biopsies of breast intraductal papillomas that were excised and followed up for longer than 5 years (Freire J. et al. BioMed Research International 2015; In Press).

HEAD AND NECK CANCER: COL11A1 was found in the desmoplastic stroma of squamous carcinomas in any localization, distinguishing them from benign lesions such as fibrosis, inflammation, leucocheratosis, ulcer, hyperplasia, etc.

KIDNEY CANCER: Collagen XI-α-1 was detected in the desmoplastic stroma of kidney carcinomas, distinguishing them from oncocytomas.

LUNG CANCER: Collagen XI-α-1 was detected in the desmoplastic stroma of lepidic-pattern adenocarcinomas, which makes the differentiation of in situ adenocarcinomas from pulmonary fibrosis possible.

OVARIAN CANCER: COL11A1 was detected in malignant ovarian tumors, distinguishing them from benign tumors and non-malignant lesions. Collagen-XI-α1 is also useful for the assessment of the invasiveness of borderline tumor implants. Increasing COL11A1 expression has been correlated with tumor invasiveness, metastasis and recurrence (Cheon, DJ. et al. Clin Cancer Res. 2014; 20(3):711-723).

BLADDER CANCER: COL11A1 was detected in the stroma of invasive bladder carcinomas (pT2), distinguishing them from superficial tumors and benign lesions (Freire et al. 2014. Pathology Journal of the RCPA. 46:S135).

Other published studies

COL11A1 has also been described as a useful biomarker for the diagnosis, prognosis and drug resistance prediction of many different tumor types:

OVARIAN CANCER: COL11A1 expression has been associated to drug resistance (Navabi, S. et al; BMC Genomics, 2016; 17(1):638; Teng, P.N. et al; Br J Cancer, 2014; 110(1):123-132) and bad prognosis (Tothill, R. W. et al; Clin Can Res, 2008; 14:5198-5208).

LUNG CANCER: COL11A1 has been related to bad prognosis (Chong, I.W. et al; Oncol Rep, 2006; 16(5):981-988) and drug resistance (Shen, L. et al; Oncol Rep, 2016; 36(2):877-885).

BREAST CANCER: COL11A1 expression in breast cancer patients has been associated to drug resistance (Farmer, P. et al; Nat Med, 2009; 15(1)68-74).

HEAD AND NECK CANCER: COL11A1 was found to be specifically expressed in metastasic oral/pharynx squamous cell carcinomas, distinguishing them from non-metastasic ones (Schmalbach, C. E. et al; Arch Otolaryngol Head Neck Surg, 2004; 130(3): 295-302). COL11A1 was also associated to tumor proliferation and invasion (Sok, j. C. et al; Br J Cancer, 2013; 109(12):3049-3056).

KIDNEY CANCER: COL11A1 expression in renal tumors has been associated to poor survival (Boguslawska, J. et al; J Urol, 2016; 195(6)1892-1902).

STOMACH CANCER: COL11A1 has been described as a good biomarker for distinguishing premalignant lesions from malignant tumors in the stomach (Zhao, Y. et al; Anat Rec (Hoboken), 2009; 292(5):692-700).

GLIOMA: COL11A1 was overexpressed in glioma tissues (An, J. H. et al; J Proteome Res, 2009; 8(6): 2873-2881).
