Peritoneal Cancer Index (Sugarbaker PCI)
Peritoneal Cancer Index (Jacquet-Sugarbaker): 13 abdominopelvic regions each scored 0-3 by lesion size (0 none, 1 <=0.5 cm, 2 <=5 cm, 3 >5 cm or confluence), summed 0-39.

What the result means
- Regions
- 13 regions (0-8 nine abdominopelvic + 9-12 four small-bowel), each scored 0-3 by lesion size (0 none, 1 <=0.5 cm, 2 <=5 cm, 3 >5 cm or confluence); total 0-39.
- Use
- higher = greater tumor burden. Selection cutoffs (e.g. colorectal ~20, lower for gastric, none strict for pseudomyxoma) are tumor-specific and advisory, not a verdict.
What you enter

- Left upper region lesion size (0 none, 1 <=0.5 cm, 2 <=5 cm, 3 >5 cm/confluence)
- Left flank region lesion size (0 none, 1 <=0.5 cm, 2 <=5 cm, 3 >5 cm/confluence)
- Left lower region lesion size (0 none, 1 <=0.5 cm, 2 <=5 cm, 3 >5 cm/confluence)
- Pelvis region lesion size (0 none, 1 <=0.5 cm, 2 <=5 cm, 3 >5 cm/confluence)
