Concept

 

Platelet Rich Plasma

Definition

 

Platelet rich plasma

 

Concept

 

2 main components

 

1.  Platelets

- contain PDGF, TGF, VEGF

 

2.  Growth factors

- ILGF

- FGF

Platelet concentration

Principles of Biopsy

Aims

 

1.  Provide representative sample

- to determine whether benign or malignant

- to determine cell line

- to grade lesion

 

2.  Not compromise definitive treatment

 

Timing

 

Last step in evaluation / after staging

 

Don't perform definitive procedure immediately after biopsy unless

- pre-operative & Xray information characteristic
