Recurrent Platinum Sensitive Primary Peritoneal Cancer

Recurrent platinum sensitive primary peritoneal cancer is a rare form of cancer that affects the peritoneum or abdomen. It is a rare form of ovarian cancer that forms on organs in the abdomen. The condition is considered recurrent if it returns after being treated and characterized as platinum sensitive if the tumor has responded to platinum-based chemotherapy.

Approximately 2-5% of women diagnosed with ovarian cancer originally have primary peritoneal cancer. Women with this type of cancer tend to have a better prognosis than those with primary ovarian cancer.

The most common method of treating this cancer is chemotherapy using drugs such as cisplatin or carboplatin with other drugs. Surgery may be done to remove tumors in the abdomen. Radiation or other treatments may also be used.


In order to diagnose recurrent platinum sensitive primary peritoneal cancer, a pelvic and abdominal exam is conducted. Blood tests may be done to determine CA-125 levels or to look for signs of ovarian cancer. Imaging tests may also be used, such as an ultrasound, CT scan or MRI. A biopsy may also be performed to confirm a diagnosis.

Recurrent platinum sensitive primary peritoneal cancer is a rare form of cancer that can be successfully treated. With proper diagnosis and treatment, many people with this cancer may have a good prognosis.
