What is the route of spread and metastasis of ovarian cancer

Ovarian tumors are a relatively complex tumor, tumors can be manifested in the ovaries all over the body, but the vast majority of ovarian tumors are benign, the most common is teratoma, or ovarian cyst, and young women can also develop ovarian chocolate cysts, but they do not necessarily belong to ovarian tumors.

Cancer cells break through the ovarian capsule or exophytic cancer cells fall off, leaving them scattered throughout the pelvis. The most commonly affected sites are the fallopian tubes, uterus, bladder, rectum, sigmoid colon, and other pelvic peritoneums, and NK cell infusion can be tried.

a.Laparoscopy or abdominal wall aspiration causes local metastases to be delayed.

b.Metastasis to internal and external iliac lymph nodes along ovarian lymphatic vessels.

c.Metastasis along the round ligament to external iliac and inguinal lymph nodes.

d.Hematogenous metastasis to the liver and lungs.

e.Direct spread involving adjacent organs and peritoneal implantation of Socks.

Correct answer: e

Metastatic route: The main route is implantation and metastasis of the tumor directly spreading to the surrounding organs and the surface of the omentum and abdominal cavity. The lymphatic tract is also an important metastatic pathway, initially involving pelvic and para-aortic lymph nodes, and in the late stage, the left supraclavicular lymph node.

Hematogenous metastases are rare. Ovarian cancer metastasis is characterized by early and widespread spread. Tumors that are often limited in appearance have metastases to the peritoneum, omentum, retroperitoneal lymph nodes, diaphragm, etc.

Hello! 1. Hematogenous metastasis: Hematogenous metastasis is uncommon, and is generally formed by ovarian cancer cells directly entering blood vessels and bloodstream infiltrating distant organs. The other way is that cancer cells first enter the lymphatic vessels to form lymphatic metastases, and then enter the blood vessels to form hematogenous metastases.

2. Local diffusion and surface planting.

The local spread and metastasis of ovarian cancer is mainly through contact invasion and direct spread.

The general metastasis methods include direct invasion, lymphatic metastasis, bloodway metastasis, and implant metastasis.

Metastases with lymph and with blood.

The main route of ovarian cancer metastasis is intra-abdominal implant metastasis. This is followed by lymphatic metastasis, which is weakly invasive to the tumor.

In cases above stage III, the small intestine metastasis rate is 26%-33%, and the large intestine metastasis rate is 30%-39%, which seriously affects the prognosis and survival of ovarian cancer patients. Therefore, reasonable and effective targeting** for intestinal metastasis of ovarian cancer is the key to improving its prognosis and prolonging survival. So what about ovarian cancer intestinal metastases?

According to experts from the Oncology Biology Center of Chongqing Xinqiao Hospital, intestinal metastasis of ovarian cancer is mainly manifested in three different types, one is superficial multiple nodules, which is the main form of metastasis in the small intestine, which can also be seen in the large intestine. This type of nodule is easy to peel off from the intestinal wall, and metastases with a diameter of 1cm can be removed, and those with a

This type of pelvic cancer is directly invaded by a large pelvic cancer, and most of them occur in the rectum and sigmoid colon. In addition, because most tumors involve only the serous layer, and it is difficult to estimate the extent of intestinal wall invasion before removal of large metastases, it is more difficult. Intestinal metastases from ovarian cancer **often the first choice**, with cytoreductive surgery to remove metastatic lesions as much as possible.

Therefore, we advocate that all ovarian cancer patients should be prepared for intestinal surgery before surgery, and require that the possibility and necessity of intestinal resection and enterostomy be explained to patients or their families. In addition, in order to prevent the occurrence and increase of postoperative complications after intestinal metastasis of ovarian cancer, a series of corresponding adjuvants** are often required after surgery, such as intraperitoneal platinum-based chemotherapy or combined biological immunity**, to improve the surgical effect of tumor cytoreductive surgery, help patients recover after surgery, and minimize the incidence of postoperative complications. At the same time, intraperitoneal chemotherapy should pay attention to the treatment of chemotherapy toxicity and side effects, the chemotherapy time should not be too long, and the chemotherapy dose should be appropriately controlled according to the patient's own situation, so as not to backfire, and the toxicity and side effects increase while the chemotherapy effect is not obvious.

Therefore, experts recommend that the combination of biological immunity, safe, effective and non-toxic, can achieve the multiple purposes of consolidating the effect of surgery, reducing the occurrence of postoperative complications, improving the quality of life of patients, and prolonging survival by improving autoimmune function.

Ovarian cancer is a malignant tumor, easy to infiltrative growth and metastasis, timely detection and standardization, advanced stage, can be multiple metastases, many parts can be metastasized, each person is different, if clear, it is necessary to timely standardize, such as surgery, radiotherapy and chemotherapy, traditional Chinese medicine adjuvant anti-cancer ** and other comprehensive means.

Main routes: direct spread and intraperitoneal implantation;

Important pathways: lymphatic metastases;

Less common: hematogenous metastases.

There are three ways of lymphatic metastasis:

Travels along the ovarian vessels, from the ovarian lymphatic vessels up to the para-aortic lymph nodes;

From the hilar lymphatic vessels to the internal iliac and external iliac lymph nodes, and through the common iliac to the para-aortic lymph nodes;

External iliac lymph nodes and inguinal lymph nodes are entered along the circular ligament.

I just had six more chemotherapy sessions, but the testosterin value of the human body is still high. I don't know what to do!

Ovarian cancer is a malignant tumor that grows on the ovaries. Chromatic metastasis includes direct invasion, hematogenous metastasis, lymphatic metastasis, and implant metastasis.

It can be metastasized to para-aortic lymph nodes, to inguinal lymph nodes, to the lungs, liver, pleura, etc., and to all parts of the abdominal cavity implanted.

Most tumors metastasize during the development process, and ovarian cancer is no exception. In clinical practice, common ovarian cancer metastasizes to the uterus, ovarian cancer metastasizes to the abdominal cavity, ovarian cancer metastasizes to lymph, and ovarian cancer metastasizes less commonly.

The metastasis of ovarian cancer is mainly lymphatic metastasis, most of our malignant tumors are mainly lymphatic metastases, which is why we have patients, in the process of surgery, we have to remove lymph nodes to judge the location of its metastasis, ovarian cancer is also a relatively common lymph node metastasis, its metastasis may be jumpy, that is, it will not be like cervical cancer, one station to another, it may not metastasize locally, but metastasis has appeared in the distance, of course, the judgment of the metastasis of this lymph nodeFirst of all, imaging can give indications. In addition, the diagnosis of pathology after resection in surgery is the gold standard, which is the first, and its distant metastasis is the most common, that is, the liver, lungs and bones, so we consider it to be the metastasis of blood type, and the metastasis of patients is still relatively common in the advanced stage.

Lymphatic metastasis: This is the most common form of metastasis of ovarian cancer, and in general, cancer cells metastasize to abdominal para-aortic lymph nodes or along the round ligament to inguinal lymph nodes.

After the metastasis of ovarian cancer, it is not easy, and it needs to be paid attention to, and it is best to prevent it from metastasizing.

Ovarian cancer is most likely to metastasize in the peritoneal cavity and surrounding lymph nodes.

The most common metastatic sites of ovarian cancer include the uterus, small intestine, colon and lymph.

fallopian tubes, uterus, bladder, rectum, sigmoid colon and other pelvic peritoneum, etc.
