valutazione di un approccio
di revisione chirurgica sistematica,
associata a chemio-ipertermia

Most of the serious complications seem to be related to the extent of surgery, and
may be related to the extent of peritoneal involvement

Morbidity: 31%
Mortality: 3%
1. The earlier the better
2. Not optimal sensitivity of
clinical, tumor markers and
imaging in detecting early
PC
Second-look surgery
Systematic use of planned reoperation in asymptomatic
patients with malignant disease who are theoretically at
risk for developing recurrent or metastatic disease
despite initial curative surgery
Largerly employed in Epithelial Ovarian Cancer during
the 90s
Which candidates?

1. Singapore general hospital
2. 3019 colorectal cancer
3. 349 (13%) developed PC
- 214 synchronous
- 135 metachronous
Logistic regression analysis for development of metachronous PC
Population-based cohort study
