1
Evaluation of Current Data suggests current screening does not work -high mortality rate -x-rays, sputum ineffective
2
Physical exam Physical exam is useful for determining risk but is ineffective for screening in early stages due to lack in symptoms
3
CT scans For majority of patients, ct scan haven’t been proven effective
4
Bronchoscopy and biopsy Methods are very invasive and are used primarily for detection
5
PET & MRI
6
Screening procedures Basically no screening done Patients walks in and are assessed for risk Smoker (10 packs a year), occupation, family history If patient is high risk, some will do x-rays, other will wait for symptoms CT scans are followed by x-rays, if anything found --> biopsy/treatment
7
Some do sputum Doctors are very negative about the process
8
Suggestions for current -Regular CT for high risk 55+ in age with 30/ packs a year (NLST) mathematical modeling available soon Eliminate x-rays -Adding a PET to a CT when available -Cell block and smear when using sputum cytology -Low-dose spiral ct scan
9
For other high risk, biannual ct scan For all high risk eliminate x-rays completely Look up AFB/WBI*
10
Grading scale for the future (high risk) Sensitivity (1-2) Specificity (1-2) Invasiveness (1) Risk (1) Practicality (1) Implementation (1)
11
Biomarkers Breath – Sensitivity: 67-100% : 3 – Specificity: 83-100% : 4 – Invasiveness: 5 – Risk: 5 – Practicality: 3 26/30
12
Biomarkers continued….. Protein blood (aptamer) – Sensitivity 91% : 5 – Specificity 84%: 4 – Invasiveness: 4 – Risk: 5 – Practicality: 5 – Implementation: 5 28/30
13
…continued…. miRNA (serum based) main/validated – Sensitivity 82/92.5: – Specififcty 77/08: – Invasiveness : 4/ – Risk: 5/ – Practicality: 5/ – Implementation: 4/
