Specific predictors and reported 5 years OS survival according to different histological type.

Histology	Specific predictors	5 years OS
Sarcoma (36–38)	- High-risk histology	From 15 to 50.9%
	- Grade 3 (G3) sarcoma
	- Bilaterality of lung metastases
Colorectal cancer (43–46)	- Preoperative CEA level	Up to 68%
	- Patient >70 years old,
	- Extra-thoracic metastatic lesions treated curatively before PM resection
	- Rectal location
Renal cell carcinoma (47)	- None	75%
Head and neck carcinomas (48–51)	- Histology	From 20.9 to 59.4%
	- Old age
	- Occurrence local recurrence before PM
Gynecological cancer (52)	- Cervix primary lesion predictive of poor survival	40.9%
