Stage 4 is the most advanced and last stage of ovarian cancer. It means cancer has spread to distant areas or organs (outside the abdomen and pelvis) in your body. Cancerous cells may be found in the spleen, liver, lungs or other organs of the body. Stage 4 ovarian cancer is further divided into two sub-stages which are:
In stage 4A of ovarian cancer, the cancer cells are found in the fluid around the lungs (also known as malignant pleural effusion) with no other areas affected.
Stage 4B of ovarian cancer indicates that the cancer has spread to the inside of the spleen or liver, to lymph nodes (besides the retroperitoneal lymph nodes), or other organs or tissues outside the peritoneal cavity (includes the lungs, the brain, and the skin).
Stage 4 ovarian cancer is not curable. Ovarian cancer is considered as one of the dangerous cancers because it is asymptomatic and is often diagnosed in its advanced stages (reason being the similarity in symptoms with other common diseases). The rates of diagnosis of ovarian cancer have remained relatively stable (a decrease of less than 1 percent annually) from the year 2000 to 2010. The mortality rate and life expectancies have also remained stable.
Most women diagnosed with Stage IV ovarian cancer have a five-year survival rate of approximately 17%. But it is different for different women. There are many things which can affect the prognosis of ovarian cancer. Other factors may also impact a woman's prognosis, including her general health, the grade of cancer, and how well the cancer responds to treatment.
The prognosis of ovarian cancer fairly depends on both the stage and the type of ovarian cancer of a patient.
There are three types of ovarian cancer:
These tumors develop in the layer of tissue on the outside of the ovaries. About 90 percent of ovarian cancers are epithelial tumors.
These tumors grow in hormone-producing cells. About 7 percent of ovarian cancers involve Stromal Tumors.
These tumors develop in egg-producing cells. Germ cell tumors are significantly rarer.
The life expectancy of ovarian cancer also depends on the time since the diagnosis of ovarian cancer is made. For example, at the time of diagnosis, the survival rate is 100 percent. But as the time increases, there is a drop in the number of stage 4 ovarian cancer survivors.
