Abstract

Methods are described for using exogenous extracellular matrix (ECM) to fill a space created after cancerous tumor excision. The extracellular matrix promotes healing at the tumor excision site. Forms of ECM that can be used include exogenous mammalian ECM in sheets, particulate and emulsion.

Claims

1. A method comprising:

identifying a cancerous tumor in a mammalian body,

excising the tumor leaving a tumor space,

filling the space left by the tumor excision with exogenous extracellular matrix, thereby promoting wound healing at the excision site.

2. The method of claim 1, wherein the cancerous tumor is carcinoma.

3. The method of claim 1, wherein the cancerous tumor is an epithelial tumor.

4. The method of claim 1, wherein the cancerous tumor selected from breast cancer, liver cancer, pancreatic cancer, lung cancer, colorectal cancer, ovarian cancer, prostate cancer, testicular cancer, bladder cancer, cervical cancer, uterine cancer, vulvar cancer, vaginal cancer, endometrial cancer, anal cancer, esophageal cancer, extrahepatic bile duct cancer, gallbladder cancer, gastric cancer, hypopharyngeal cancer, laryngeal cancer, nasopharyngeal cancer, non-small cell lung cancer, small cell lung cancer, neuroblastoma, adrenocortical cancer, lip cancer, oral cavity cancer, oropharynx cancer, mesothelioma, soft tissue sarcoma, glioma, gastrointestinal cancer, penile cancer, parathyroid cancer, pituitary cancer, salivary gland cancer, thyroid cancer, skin cancer, and renal cancer.

5. The method of claim 1, wherein the cancerous tumor is of one of approximately 100 known cancers.

6. The method of claim 1, wherein the extracellular matrix is mammalian.

7. The method of claim 1, wherein the extracellular matrix is selected from porcine, bovine, and human origins.

8. The method of claim 1, wherein the exogenous extracellular matrix is selected from small intestine submucosa, liver basement membrane, stomach submucosa, and urinary bladder submucosa.

9. The method of claim 1, wherein the exogenous extracellular matrix is in a form selected from a sheet, an emulsion, and a particulate.

11. The method of claim 9, wherein contacting comprises substantially filling the tumor space.

12. The method of claim 9, wherein after surgical closure the exogenous extracellular matrix generates healthy tissue at the excision site.

10. A method comprising:

excising an epithelial tumor from a mammal and at least some surrounding tissue forming a tumor excision site,

contacting the tumor excision site with exogenous mammalian extracellular matrix, and

surgically closing the site.
