Ovarian symptoms of colon cancer metastasis?
summary
Colon cancer is a common malignant tumor, which occurs at the junction of rectum and sigmoid colon, and the incidence rate is third of gastrointestinal tumors. According to epidemiological data, the incidence rate of this disease is increasing. The age of onset can be seen at any age. The incidence rate is highest in the 40~50 year old group. The metastatic characteristics of ovarian malignancies are: the tumor with limited appearance is transferred to the peritoneum, greater omentum, diaphragm, liver surface and retroperitoneal lymph node. Ovarian symptoms of colon cancer metastasis? Let's talk about it.
Ovarian symptoms of colon cancer metastasis?
1) Direct implantation: exfoliated ovarian cancer cells can be implanted in various parts of the abdominal cavity and continue to grow. The most common sites of metastasis are peritoneum, which is the parietal peritoneum of abdominal cavity and the visceral peritoneum covering the surface of various abdominal organs. The latter includes diaphragm, omentum, mesentery of small intestine, rectum, hysterorectal fossa, colon and serosa of uterus of oviduct. Among the above metastatic sites, the space between the uterus and rectum, that is, the uterine rectal fossa, is the most common. The reason may be that this is the lowest part of the abdominal cavity. Due to gravity, early ovarian cancer can have exfoliated cells deposited here and grow here. Ovarian cancer is one of the bases of intraperitoneal chemotherapy.
2) Local spread growth: the primary ovarian cancer gradually grew and extended, involving the adjacent uterus, fallopian tube and vagina. However, studies have shown that the transfer of these organs is often superficial, and the transfer to the interior is rare.
3) With lymphatic drainage and diffusion: due to the clinical manifestation of ovarian cancer with intraperitoneal implantation and local invasion, lymphatic metastasis, an important metastasis pathway of ovarian cancer, has been ignored for a long time. Previously, it was thought that the lymphatic drainage of the ovary was upward to the lymph nodes located near the abdominal aorta, but now it has been found that the lymphatic fluid of the ovary can also be drained downward to the pelvic lymph nodes. After a long-term study, Peking Union Medical College Hospital has basically clarified the regularity of lymph node metastasis of ovarian cancer, and found that the chances of metastasis of ovarian cancer to the above two sites are almost equal. At the same time, it is found that lymph node metastasis of ovarian cancer is not rare, even for clinical stage I ovarian cancer, 10% of them may have lymph node metastasis. On this basis, persistent retroperitoneal lymphadenectomy has improved the prognosis of some patients.
matters needing attention
In the process of early colon cancer treatment, traditional Chinese medicine treatment is more auxiliary to other treatment methods. Preoperative treatment with traditional Chinese medicine can reduce tumor size, improve resection rate, reduce regional lymph node metastasis, intraoperative dissemination of cancer cells and local recurrence; Postoperative use of traditional Chinese medicine treatment, not only can remove the residual lesions, inhibit the probability of postoperative recurrence and metastasis, but also can reduce the surgical trauma, inhibit the postoperative complications. Through TCM treatment of patients with body conditioning, patients can get early rehabilitation. Moreover, TCM treatment can also assist radiotherapy, reduce the toxic and side effects of radiotherapy, and improve the therapeutic effect of radiotherapy.
