Stomach cancer Brain metastases, where stomach cancer tends to metastasize

Here's a method that I hope will help you.

The anatomical basis of API-specific biological immunity** is the functional system of the human immune system. It is based on the in-depth study of the interaction mechanism between tumor and the immune system, a comprehensive understanding of the biological characteristics of tumors, and a new theoretical basis provided by modern tumor biology. The immune system is an organizational system in which humans and higher animals recognize self and non-self, trigger immune responses, perform immune effects, and ultimately maintain autoimmune stability.

The immune system is divided into two related functional systems: innate, heritable, and non-specific recognition of innate immunity (non-specific immunity, passive immunity) and acquired, targeted, immuno-memory, non-hereditary, and individual-specific acquired immunity (specific immunity, active immunity), which can monitor tumor immunity, that is, active and passive immune mechanisms. The surveillance effect of the immune system on tumors inhibits the development, growth, and metastasis of tumors, and may lead to the natural regression of some malignancies. The First Affiliated Hospital of the General Hospital of the People's Liberation Army (304 Hospital).

Depending on the general condition of the patient, if the general condition is acceptable, it is not recommended to give up the opportunity, but only accept simple maintenance. At present, there are more advanced methods for brain metastasis, and whole-brain radiotherapy is the most accurate means for the efficacy. In addition, see if you are new brain metastases, or have gone through multiple processes**, have you checked the amplification of HER-2 in the past, and see if there are ** indications for molecularly targeted drugs.

Nowadays, there are many ways to treat tumors, and it is recommended to go to a regular hospital for acceptance.

Stomach cancer brain metastasis is recommended to be conservative in traditional Chinese medicine** You can take name protectors, which can enhance immunity and prolong life.

It is recommended that Chinese medicine **, Chinese medicine is relatively peaceful, no ***, patients are generally acceptable, and most cancer patients can reduce pain and prolong life by taking Chinese medicine.

Adjusting the mentality and actively cooperating** can reduce symptoms, improve the quality of life, and prolong survival.

Lymphatic metastases are common in stomach cancer.

Answer]: A abdominal tumor is prone to metastasis to the left supraclavicular lymph node, and thoracic tumor to the right supraclavicular lymph node.

"What are the routes of spread and metastasis of gastric cancer? "Children's shoes preparing for the gastroenterology title exam come and check it out! Here's a summary of the Medical Education Network:

The spread and metastasis of gastric cancer can be done in the following ways:

1.Direct infiltration.

Cardia fundus cancer tends to invade the lower end of the esophagus, and antral cancer can invade the duodenum. Poorly differentiated and infiltrative gastric cancer breaks through the serous membrane and tends to spread to adjacent organs such as the omentum, colon, liver, and pancreas.

2.Hematogenous metastases.

In advanced stages, cancer cells enter the portal vein or systemic circulation and spread to other parts of the body, forming metastases. Common metastases include liver, lungs, pancreas, bones, etc., and liver metastases are the majority.

3.Peritoneal implant transfer.

When gastric cancer tissue infiltrates outside the serosa, tumor cells are detached and implanted on the peritoneum and organ serosa, forming metastatic nodules. Peritoneal implantation is most likely to occur in the upper abdomen, mesentery. Implantation of the rectum and bladder is a sign of advanced gastric cancer.

Metastatic cancer in the anterior fovea of the rectum can be detected on digital rectal examination. Female patients with gastric cancer can develop ovarian metastatic tumors.

4.Lymphatic metastases.

It is the main metastatic route of gastric cancer, and the lymphatic metastasis rate of advanced gastric cancer is as high as about 70%, and early gastric cancer can also have lymphatic metastasis. There was a positive correlation between the rate of lymph node metastasis and the depth of invasion of gastric cancer. Lymph node metastasis in gastric cancer is usually gradual and gradual, but skipping lymphatic metastasis can also occur, that is, there is no metastasis at the first station and metastasis at the second station.

End-stage gastric cancer can metastasize to the left supraclavicular lymph node through the thoracic duct or to the umbilical cord through the round hepatic ligament.

There are 4 ways of metastasis of gastric cancer, usually lymphatic metastasis and direct spread, and hematogenous metastasis can also occur in advanced stages. In addition, cancer cells can be planted directly in the abdominal cavity.

1) Direct spread: After the cancer grows and invades the stomach wall, it develops in the direction of depth, breaks through the serous layer, and can directly invade adjacent organs and tissues, with omentum, liver, pancreas, and transverse colon being common, followed by jejunum, diaphragm and abdominal wall. Direct spread is related to the surgical method and whether it can be resected first-class, generally spread to adjacent organs, such as the liver, which can be surgically removed when the scope is small and limited, and it is difficult to remove all the surgery when the scope is large.

According to the order of transfer, they are divided into 3 stations or 3 groups. The first group (station) is the closest to the tumor, which is a superficial group of lymph nodes attached to the stomach wall, which generally occurs when gastric cancer is confined to the submucosa. The second group (station) is the deep group of lymph nodes that drain superficial lymph nodes, and the second group of lymph node metastasis can occur when gastric cancer invades the muscles.

The third group (station) included paraceliac artery, abdominal aorta, hepatic hila, mesenteric root, and pericolonic lymph nodes; Distant lymph node metastases, such as the left supraclavicular lymph node, can also occur. Metastases in this group mostly occur when the cancer invades the serosa. In general, the opportunity for metastasis to occur in the third group of lymph nodes has been lost.

3) Hematogenous metastasis: Some patients may develop gastric cancer cells or cancer thrombis circulating to other organs in the body through the bloodstream. It can metastasize to the liver, lungs, bones, kidneys, spleen, brain, meninges,**, and can also metastasize to the ovaries to form Krukenberg's carcinoma of the ovaries or mucinous cell carcinoma of the ovary.

Hematogenous metastasis mostly occurs in the advanced stage of gastric cancer, and metastases are also required in addition to the primary lesion.

4) Intraperitoneal implantation and metastasis of gastric cancer cells: In a few cases, the cancer breaks through the serosa of the gastric wall, and the cancer tissue dies and falls off, falling off to other organs and peritoneum, and implant growth can occur; In advanced stages, carcinomatous peritonitis can develop with bloody ascites, and sometimes cancer cells can be found in the ascites that is withdrawn. Patients with implant metastases are all in the advanced stage, which is more difficult, and is often given intraperitoneal injection of chemotherapy drugs, but due to extensive metastasis, it can often only prolong life, but not **.

Gastric cancer is most likely to metastasize to the lungs, liver, and kidneys, because they are very close, it is recommended that if you have stomach cancer, you must have surgery as soon as possible to remove it in the early stage, so as not to delay the condition, so as not to have more serious consequences

Gastric cancer metastasis pathwayGastric cancer metastasis pathwayThe early gastric cancer symptoms are atypical, the younger the age of gastric cancer patients, the shorter the course of the disease, the shortest course of the disease is only half a year, a considerable number of patients have metastasis and are more extensive at the time of diagnosis, and cachexia appears quickly. The liver and abdominal cavity are common metastasis sites for gastric cancer, and ascites can occur when the abdominal cavity metastasizes extensively, and the left supraclavicular lymph node is also a common metastasis site for gastric cancer. So what are the pathways of gastric cancer metastasis?

One of the ways of gastric cancer metastasis - planting and metastasizing cancer cells that fall off on their own or due to surgical operations can be planted like seeds in the chest, abdominal cavity, surgical incision, etc., to form new organisms, that is, cancer metastases. After the cancer cells are shed, there are certain conditions for the formation of implantation metastasis, that is, ** or there are breaks on the mucosal surface. Cancer cells are most likely to be planted on the surface of the pleura and peritoneum, and cancer cells of gastric cancer are often implanted in the abdominal cavity and pelvic organs, such as the intestines, ovaries, diaphragm, gall bladder, rectal surface, etc., often forming tumors locally, producing serous or plasma ascites.

It has been reported that the autopsy implantation transfer rate is . Lymph node metastasis accounts for 70% of gastric cancer metastasis, and lower gastric cancer often metastasizes to subpyloric, subgastric and paraceliac lymph nodes, while upper cancers often metastasize to parapancreas, paracardia and gastric lymph nodes. Advanced cancer may metastasize to peri-aorta and supraphrenic lymph nodes.

Because of direct communication between the abdominal lymph node and the thoracic duct, it can metastasize to the left supraclavicular lymph node. Gastric cancer metastasis pathwayThe third metastatic gastric cancer metastasis - direct metastasis invasive gastric cancer can develop directly into the stomach wall, esophagus or duodenum along the mucosa or serous membrane. Once the cancer invades the serosa, it is easy to infiltrate into the surrounding organs or tissues such as the liver, pancreas, spleen, transverse colon, jejunum, diaphragmatic omentum and abdominal wall.

When cancer cells are shed, they can also be planted in the abdomen, pelvis, ovaries, rectum, bladder sockets, etc. Gastric cancer metastasis pathway 4 - hematogenous metastasisSome patients can find cancer cells in the peripheral blood, which can metastasize to the liver through the portal vein, and can reach the lungs, bones, kidneys, brain, meninges, spleen, **, etc.

Hello, after the malignant tumor cells are shed from the "mother", they follow various pathways to reach new organs or lymph nodes, where they take root and grow a tumor of the same type as the original tumor, which is called metastasis. The main metastases are lymphatic at present. Learn more (adhere to the sunny life, Tang Junhua) change,

Gastric cancer is prone to distant metastasis, metastasis to the liver, lungs, kidneys, etc., and one of the special cases is that gastric cancer metastasizes to the ovaries, which is often referred to as Krukenberg tumor (i.e., Keukenberg tumor). Gastric cancer metastasis to the ovaries is not only metastasis in a way that is relatively rare implant metastasis, but also.

Gastric cancer is a relatively high incidence of malignant tumors in China, and the elderly are the main group affected by gastric cancer, and some patients will metastasize to gastric cancer after **. Gastric cancer patients must lose no time in undergoing various examinations and long-term health**, so that they can truly and effectively control the disease. The harm of advanced gastric cancer is relatively large, and many people are worried about the metastasis of advanced gastric cancer, because gastric cancer is very common after surgery** and metastasis.

Many people also wonder why advanced gastric cancer is prone to metastasis or **?

Before surgery, many stomach cancer patients have very low immunity, resulting in a decrease in the body's defense function, that is, the ability of immune cells in the body to recognize and kill cancer cells is reduced; In addition, surgical trauma and anesthesia more invade the body's immune system, resulting in lower immunity. Elderly gastric cancer patients tend to have a lower degree of malignancy, while younger gastric cancer patients have a relatively high degree of malignancy and a poor prognosis. Generally speaking, cancers with a high degree of malignancy and strong resistance to chemotherapy are more likely than cancers with a low degree of malignancy and sensitivity to chemotherapy.

Patients with advanced gastric cancer have penetrated the stomach wall and invaded the abdominal cavity and adjacent organs and tissues before undergoing surgery**; or metastases through lymphoid tissue to distant sites. Moreover, there are certain risks associated with any surgery, and gastric cancer patients may have some accidents when undergoing surgery, resulting in incomplete surgery. Immunity is also a great factor in the metastasis of advanced gastric cancer.

If gastric cancer is not treated in time, or metastasis is a concurrent phenomenon, in fact, there are many such patients, because the symptoms of early gastric cancer are not very obvious, delaying the early time, and then the patient has been ignoring their own health, resulting in the phenomenon of gastric cancer metastasis, there are many kinds of gastric cancer metastasis, how to decide according to the specific situation of the disease.

Tumor spread includes the process of tumor invasion and metastasis, which refers to the direct spread of tumor cells, that is, from the primary site through the tissue space, lymphatic vessels, blood vessels, body cavity or cerebrospinal cavity to nearby or distant organs and tissues, involving the corresponding organs, which is often an inevitable stage in the growth process of malignant tumors. Metastasis refers to one or more tumors that grow out of malignant tumor cells separated from the main body of the primary tumor and secondary to tissues and organs that are not connected to the primary tumor or are far away, and the pathological tissue type of this new tumor is basically the same as that of the primary tumor, and the pathways of metastasis include lymph, blood vessels, implantation, etc.

Gastric cancer is a serious disease that may be more common in the current society, which not only endangers the physical and mental health of patients, but also affects our normal life, and may even threaten life, so we have to prevent it. After surgery, we must pay attention to strict prevention**, so we should try to improve our own immunity and enhance our physical fitness to resist the occurrence of diseases.

Patients with metastasis of gastric cancer should not be overly nervous, a good attitude and appropriate Chinese medicine** can effectively improve the patient's condition. Gastric cancer patients usually pay attention to dietary conditioning and nursing, and pay attention to nutritional health care to avoid metastasis and deterioration of gastric cancer in the advanced stage. Once gastric cancer patients show the above signs of metastasis, they should go to the hospital in time and adopt the corresponding methods, and most patients can still achieve good results.

Don't worry too much, stomach cancer chemotherapy patients are very weak, so you should improve your body's immunity through diet. In the diet, you should eat more foods with high selenium content, and you can choose high-activity selenium supplementation preparations to improve the patient's immunity, reduce the duration of chemotherapy, and increase the effect of chemotherapy. If the diet can be appetizing, you can eat diced hawthorn pork, astragalus yam soup, and cordyceps roast beef, which is clinically verified.
