Peritoneal cytology endometrial cancer

  • Can endometrial cancer spread to the peritoneum?

    Endometrial cancer may disseminate through lymphatic channels to pelvic and retroperitoneal lymph nodes, through the bloodstream to the lungs, or through the peritoneal space to peritoneal surfaces.
    However, not all endometrial cancers involve all 3 sites for metastatic disease..

  • What is peritoneal cytology in endometrial cancer?

    Patients with positive peritoneal cytology for endometrial cancer have a high risk of recurrence, regardless of histopathologic type or FIGO stage.
    Peritoneal cytology has already been removed from the 2009 FIGO classification of endometrial cancer, but it may deserve reconsideration..

  • What is the gold standard for endometrial cancer?

    Whatever starts the process, it's important to keep in mind that an endometrial biopsy (when a tissue sample is removed from the inner lining of the uterus) is the gold standard test for diagnosing endometrial cancer..

  • Endometrial biopsy: When a small tissue sample is taken from the inner lining of the uterus.
    A thin tube is inserted through the cervix into the uterus, and a sample is gently scraped off for examination under a microscope.
    This is done to see if cancer or other abnormal cells are present.
  • Endometrial carcinoma is divided into numerous histologic categories based on cell type (Table 1).
    The most common cell type, endometrioid, accounts for 75% to 80% of cases.
    Due to its common occurrence, this variant is also known as typical endometrial adenocarcinoma.
  • Peritoneal cytology.
    The cytologic evaluation of peritoneal fluids, or washings, has been recognized as an important prognostic and staging factor in pelvic malignant neoplasms.

Patients with positive peritoneal cytology for endometrial cancer have a high risk of recurrence, regardless of histopathologic type or FIGO stage. Peritoneal cytology has already been removed from the 2009 FIGO classification of endometrial cancer, but it may deserve reconsideration.
Introduction: In endometrial cancer, malignant peritoneal cytology (MPC) refers to the presence of tumor cells in the peritoneal cytologic specimen obtained at hysterectomy.

Does ovarian cancer have positive peritoneal cytology at laparotomy?

OVARIAN NEOPLASMS 48 to 60% of women with ovarian cancer have positive peritoneal cytology at laparotomy. [2,4,5,15,16,48]Although often accompanied by sheets of polymorphic mesothelial cells, the morphology of the malignant cells in the PWs is often similar to that seen in spontaneous effusions.
However, problematic patterns do occur.

Does PPC influence the prognosis of early stage endometrial cancer?

Studies show that PPC does not influence the prognosis of stage III cancers unlike other factors like lymph node metastasis, and uterine serosal or adnexal metastasis, but it is unclear whether PPC influences the prognosis in patients with early stage endometrial cancer (EEC) 5, 6, 7.

  1. Positive peritoneal cytology was associated with decreased overall survival of women with Federation International de Gynecologie et Obstetrique stage I/II endometrial cancer
  2. including :
  3. low-grade endometrioid endometrial cancer

What causes positive Peritoneal washing in endometrial cancer?

[15,16]Occasionally, positive peritoneal washings in endometrial cancers can be seen with deep myometrial invasion, presumably through lymphatic permeation. [64,69]• Some cases may be associated with transit of the tumor cells through patent fallopian tubes.
