Clinicopathologic features of five cases of PPSS

Case	Age	Tumor size	LN	Subtype	Treatment	Outcome	Survival
1	28	3.5 × 2.2 cm2	N	monophasic	Excision + rad + chemo	ATPM	78 m
2	41	2.9 × 2.7 cm2	N	biphasic	Excision + rad	ANED	57 m
3	22	4.0 × 3.1 cm2	0/8	biphasic	Excision + rad	ANED	53 m
4	31	5.2 × 4.9 cm2	0/21	biphasic	Excision + rad + chemo	DOR	26 m
5	37	6.6 × 5.1 cm2	N	monophasic	Excision + rad	DOPM	37 m

ANED alive with no evidence of disease, ATPM alive with pulmonary metastasis, DOPM died of pulmonary metastasis, DOR died of tumorous recurrence, LN indicates lymph node metastases, m months, N no check.
