Pathways of Metastases from Primary Organs to the Ovaries

Table 3

The pathways of metastases to the ovary and the differences in prognosis between time and space.

Site of original cancer	Ovarian lymphangio invasion	𝑃 value	Ovarian vascular invasion	𝑃 value	Liver metastasis	𝑃 value
Gastric cancer	57% (4/7)	𝑃<0.05	0% (0/7)	𝑃<0.05	0% (0/7)	NS
Colorectal cancer	0% (0/6)		67% (4/6)		17% (1/6)
Site of original cancer	Pathological direct invasion	𝑃 value	Bilateral ovarian metastasis	𝑃 value
Near the ovaries	57% (4/7)	𝑃<0.05	57% (4/7)	NS
Distant from the ovaries	0% (0/11)		45% (5/11)
Site of original cancer	Time of treatment for metastatic ovarian tumor	Number (without alive one)	Ovary-specific survival (years) (without alive one)	𝑃 value
Near the ovaries	At the same time	3	2.67 ± 2.08
Distant from the ovaries		7	1.60 ± 0.84*	* 𝑃<0.05
Near the ovaries	Later	1	4
Distant from the ovaries		6	3.17 ± 2.11*

Near the ovaries: sigmoid colon, rectum, appendix, small intestine, and uterine corpus, distant from the ovaries: stomach, ascending colon, transverse colon, and gall duct, ovary-specific survival: date of ovarian metastasis diagnosis to death.
