Explanation

The primary lymphatic drainage of carcinoma of the ovary typically goes into the para-aortic lymph nodes

Due to the anatomical location and lymphatic pathways of the ovaries.

The para-aortic lymph nodes, also known as the lumbar lymph nodes

They are located near the aorta in the abdomen.

The lymphatic vessels from the ovaries converge and drain into the para-aortic lymph nodes, along with lymphatic vessels from other pelvic organs such as:

• the uterus
• fallopian tubes
• part of the vagina

Carcinoma of the ovary often spreads initially to nearby structures within the pelvis and abdomen.

Due to the close proximity of the ovaries to the para-aortic lymph nodes

And the pattern of lymphatic drainage in the pelvic region, metastatic cancer cells from the ovaries are likely to travel

Through the lymphatic vessels and reach the para-aortic lymph nodes.
