Are ovarian cancer stages? Divided into several phases

Among women, breast cancer and cervical cancer have the highest incidence rates. Secondly, women are also very likely to develop ovarian cancer. The onset of ovarian cancer is generally divided into four stages. Early ovarian cancer is easy to detect because there are no symptoms of tumors and ascites in the ovaries in the first stage. Ovarian cancer can also metastasize cancer cells very quickly, so women need to have their ovaries checked in a timely manner. Do you understand the staging of ovarian cancer in detail?

1. The first stage of ovarian cancer staging: The lesion is limited to the ovary. According to clinical reports, for patients with advanced ovarian cancer with extensive metastasis, ideal results can still be achieved by performing tumor cell reduction surgery or massive resection combined with chemotherapy based on accurate ovarian cancer staging. Stage a: The lesion is limited to one ovary, the capsule is intact, there is no tumor on the surface, and there is no ascites; Stage b: The lesion is limited to both ovaries, the capsule is intact, there is no tumor on the surface, and there is no ascites; Stage c: Stage Ia or Ib lesions have penetrated the surface of the ovary, or the capsule has ruptured, or malignant cells are found in the ascites or peritoneal washings.

2. The second stage of ovarian cancer staging: the lesion involves one or both ovaries, with pelvic metastasis. The accuracy of clinical surgical staging of ovarian cancer is easily affected by subjective factors, while abdominal and pelvic CT scanning can make up for the shortcomings of surgical staging. The accuracy of preoperative staging can reach 70%~90%. Stage A: The lesion extends or metastasizes to the uterus or fallopian tubes; Stage B: The lesion extends to other pelvic tissues; Stage C: Stage IIa or IIb lesions, the tumor penetrates the surface of the ovary; or the capsule ruptures; or malignant cells are found in the ascites or peritoneal washings.

3. The third stage of ovarian cancer staging involves one or both ovaries, with implantation outside the pelvis or retroperitoneal lymph node metastasis: Stage A: The lesion is grossly confined to the pelvis, with negative lymph nodes, but microscopically there are implants on the peritoneal surface of the abdomen; Stage B: The diameter of the peritoneal implant is <2cm, with negative lymph nodes; Stage C: The diameter of the peritoneal implant is ≥2cm, or there is retroperitoneal or inguinal lymph node metastasis.

4. Stage 4 of ovarian cancer staging: Malignant cells must be found when distant metastasis ascites is present; Liver metastasis (involving the liver parenchyma). Ovarian cancer staging is of great significance for the treatment of ovarian cancer. It can help patients understand their own condition and better guide treatment plans. At the same time, combined with various examinations such as CT, ultrasound, and X-ray angiography, appropriate adjustments to the diagnosis and treatment plan can fundamentally reduce the number of laparotomies for patients and improve treatment outcomes. The treatment and prognosis of ovarian cancer are closely related to the stage and tissue grade of ovarian cancer.
