Pancreatic cancer is the 4th most common cause of cancer-related deaths
5-year survival is only 10-24%
PDA arises from ductal cells of the pancreas
Method of detection
Laser capture microscopy
use a laser to accurately cut out only the part of the tissue
sample that is to be analysed. e.g. te ductal cells and discard
the remaining tissue around it
Analyse the different spots observed between diseased samples
and healthy controls using tissue array. e.g. Western blot
Identify the spots found only in disease tissues using mass spectroscopy
Validate the process
tissue arrays
linkeage analysis
S100A6 (Calcylin) identified as being associated with poor survival in PDA
PROSTATE CANCER
intro
Most common male cancer in the Western world
3rd leading cause of cancer deaths among men
currently the diagnosis involves
PSA measurements
digital rectal exams
transrectal ultrasound guided sonography
over-diagnosis and over-treatment
treatment based on whether disease is organ confined
Detection
literature review
sample collection and preparation
protein separation by 2-DE DIGE
gel image analysis to look for any spots in diseased gel not in healthy control gel
