Whether you’re familiar with LGSOC or looking for more information, there’s always more to learn.

What is LGSOC?

Low-grade serous ovarian cancer (LGSOC) is a rare ovarian cancer.

AT WHAT AGE

are women typically diagnosed with LGSOC?

While LGSOC can affect women of many different ages, it’s most often diagnosed between the ages of 20 to 30 and 50 to 60. Over 90% of patients with LGSOC are diagnosed at an advanced stage.

HOW


is LGSOC diagnosed?

Your healthcare provider will take a small sample of tissue from your tumor that another healthcare provider called a pathologist will then test to confirm an LGSOC diagnosis. They may also perform additional testing to detect changes and mutations in your body’s cells.

WHAT

is a KRAS mutation?

The KRAS gene mutation occurs in about 30% of LGSOC cases and is the most common type of mutation seen with LGSOC.

WHAT

is recurrent LGSOC?

After surgery and treatment, LGSOC may come back, which is known as a recurrence. In fact, over 80% of women with LGSOC experience a recurrence. Avmapki Fakzynja Co‑Pack is the first treatment specifically approved to treat women with KRAS-mutated recurrent LGSOC.
