We sought to determine the validity of cancer antigen CA and the risk of malignancy index RMI in the diagnosis of ovarian cancer in women presenting with adnexal lesions of various histopathology types. This retrospective cross- sectional study included all women with adnexal lesions who were evaluated at the Royal Hospital, Oman, between January and December The inclusion criteria included women who underwent surgical intervention and who had preoperative CA testing and pelvic ultrasound in the work-up plan of their management. The surgical intervention was usually followed by a histopathological diagnosis of the nature of the lesion, which was used as the gold standard for the evaluation of both CA and RMI. The cohort included women who had serum CA and pelvic ultrasound prior to the surgical intervention of the adnexal lesion. Both tests were more sensitive in detecting epithelial ovarian cancer compared to other ovarian cancers. CA has higher sensitivity; however, RMI has higher specificity.

A CA test may be used to monitor certain cancers during and after treatment. In some cases, a CA test may be used to look for early signs of ovarian cancer in people with a very high risk of the disease. A CA test isn't accurate enough to use for ovarian cancer screening in general because many noncancerous conditions can increase the CA level. Many different conditions can cause an increase in CA , including normal conditions, such as menstruation, and noncancerous conditions, such as uterine fibroids. Certain cancers may also cause an increased level of CA , including ovarian, endometrial, peritoneal and fallopian tube cancers. To monitor cancer treatment.

CA cancer antigen , carcinoma antigen , or carbohydrate antigen also known as mucin 16 or MUC16 is a protein that in humans is encoded by the MUC16 gene. Mucin 16 is a membrane associated mucin that possesses a single transmembrane domain. MUC16 is composed of three different domains: [9]. The N-terminal and tandem repeat domains are both entirely extracellular and highly O-glycosylated. All mucins contain a tandem repeat domain that has repeating amino acid sequences high in serine , threonine and proline. MUC16 is a component of the ocular surface including the cornea and conjunctiva , the respiratory tract and the female reproductive tract epithelia.

Is there a method of early detection, or a way to screen for ovarian cancer? At this time, no. No studies have shown that currently available tools or approaches are effective at preventing women from dying from ovarian cancer. What is CA? A test that determines how much CA is in the blood is among the blood tests that may be ordered by a doctor if ovarian cancer is suspected. How is the CA test used?



Serum CA-125 measurements > 65 U/mL. Clinical value.

This test measures the amount of a protein called CA cancer antigen in the blood. CA levels are high in many women with ovarian cancer.
