How Chemosensitive Is This Tumor Right Now?
For How Long?
When Should We Stop?

Our mission: Reduce unnecessary chemo by answering these critical questions before treatment starts.

One Simple Score Answers Everything

CSI (ChemoSensitivity Index) is a score from 0-100 that predicts how well chemo will work for this specific patient, right now.

72
High Score
Continue Treatment
Chemo will likely work. Proceed with confidence, monitor for optimal duration.
6+ months benefit
Expected response duration
50
Medium Score
Re-Evaluate
Consider combination therapies or re-evaluation. Benefit is uncertain.
3-6 months
Expected response duration
28
Low Score
Avoid Unnecessary Treatment
Avoid unnecessary treatment. Explore alternative strategies or trials.
<3 months
Expected response duration
Real Example

Sarah, 58, ovarian cancer. Ovarian cancer patient, 2nd-line, evaluating PARP inhibitor after platinum

CSI Score
72/100
Recommendation
RECOMMEND PARPi
High probability of 6-month PFS

Validated on 2,200+ patients. This specific scenario validated in TOPACIO trial (AUROC 0.714, p=0.023).

Three Questions. One Score. Clear Answers.

Will this chemo work?

CSI ≥70 = Yes, likely to work. CSI <40 = No, probably won't work.

For how long?

CSI predicts 6-month benefit probability. Higher score = longer expected benefit.

When should we stop?

If CSI drops below 40, chemo is unlikely to help. Save patient from unnecessary side effects.
