Ovarian Cancer is one of the most critical cancers in a woman’s body that arises in the ovaries. In most of the cases, it is believed to be present at the ovarian surface. However, in some cases, this cancer may even be noted to start in the fallopian tubes. The worst part about this type of cancer is that the symptoms at the early stages are not so popular and thus, cannot be easily detected.
Most of the cases are diagnosed at a later stage. The ovarian cancerprognosis is thus based on the stage at which this cancer is detected.
Factors That Affect the Prognosis of Ovarian Cancer
There are a number of factors that can affect the ovarian cancer prognosis. First of all, it is essential to find out the stage at which the cancer is detected. The earlier it is detected, the longer is the life expectancy of the individual. However, there are other factors that work collectively with the stage to determine an approximate time period of survival after detection of ovarian cancer. These include cytological analysis of the peritoneal fluid, the grade of cancer, the volume of tumor, certain serum levels and some analysis of the DNA.
Prognosis of Ovarian Cancer Based on Various Factors
Ovarian cancer prognosis is considered after the cancer has been detected. The survival rate as per some of the recent researches shows that around 3/4th of the women survive for a minimum period of 1 year after detection.
Slightly less than half of the women survive for 5 years. However, this depends to a great extent on the age of the lady as well. If the woman is young, she is likely to stay alive for longer as compared to an old lady at the same stage of cancer.
Survival Rate Percentage
The 5-year survival rate percentage as per the ovarian cancer prognosis is as states. Stage I- 89%, IA- 94%, IB- 91%, IC- 80%, II- 66%, IIA- 76%, IIB- 67%, IIC- 57%, III- 34%, IIIA- 45%, IIIB- 39%, IIIC- 35% and IV- 18%. The tumors with less risk exposure display the following 5-year rate of survival: Stage I- 99%, Stage II- 98%, Stage III-96% and Stage IV- 77%. There are two other types of cancer prognosis that include the tumor at the germ cells of ovary and that in the fallopian tube. For the former, the 5-year survival rate is:Stage I- 98%, Stage II- 80% (dependent on other factors as well), Stage III- 84%, Stage IV- 55%. For the latter, the chances are: Stage I- 93%, Stage II- 74% (dependent on other factors as well), Stage III- 66% and Stage IV- 40%.
Grading of the Stages
Ovarian cancer prognosis is also dependent on grades for some of the stages. Grading system is mainly essential to determine the survival rates of patients in Stage I of cancer. This is important to determine whether chemotherapy is likely to produce favorable results. For the fallopian tube ovarian cancer, grading is essential to determine whether to operate or not. It is thus classified into high grade and low grade. The ones with low grade Stage I can be treated with chemotherapy.
