Resource Center

The key to battling any serious illness is education. If you are a patient or a loved one searching for answers after a diagnosis of mucinous ovarian cancer (MOC), you might be feeling frustrated by how difficult information is to come by.

We get it. We’ve been there.

To help families learn more about the disease, we created this Resource Center. Our goal is to help families learn more about MOC, including what it is and why it’s so different. We also share links to research you might find insightful.

What Is Mucinous Ovarian Cancer (MOC)?

Mucinous ovarian cancer is a rare and distinct type of epithelial ovarian carcinoma (EOC). Tumors tend to be large, with a median diameter of 18 to 20 cm, or 7.087 to 7.874 inches.

In the past, MOC was often misdiagnosed as various types of gastrointestinal cancer, such as colon or pancreas. That’s because at an advanced stage, MOC can be difficult to distinguish from cancers that started elsewhere (colon, appendix, pancreas, stomach) and spread to the ovary.

This led researchers to believe 10%–15% of ovarian cancer diagnoses were MOC. In the last few years, however, the scientific community has gotten better at diagnosing MOC. Clearer criteria have resulted in a refinement in the number of cases. We now know that the number is actually 3% of all ovarian cancer diagnoses in the US, and 4%–5% worldwide.

Treatment typically involves both surgery to debulk the tumor and chemotherapy. Instead of standard ovarian cancer chemotherapy, gastrointestinal chemotherapy may be used. While there is no definitive evidence yet to prove how effective it is, researchers believe this treatment may be more suitable because the pathology of MOC aligns with gastrointestinal cancers.

Targeted therapy based on a patient’s personal tumor profile is also increasingly being explored for women with MOC.


As is true of any type of rare cancer, you may wish to seek a second opinion. Learn more about second opinions for mucinous ovarian cancer, including physicians to consider, here

Learn More About Mucinous Ovarian Cancer

We recognize much of the information found online is technical and tough to understand for patients who aren’t clinicians. One goal of the Coalition is to develop easy-to-read, downloadable resources. Look for our Resource Center to expand as the Coalition grows.

In the short-term, we encourage you to visit and review:

• Ovarian Cancer: Epithelial Ovarian Cancer: Created by the National Comprehensive Cancer Network (NCCN), an alliance of 28 cancer centers across the country, this step-by-step guide helps patients better understand their disease, from diagnosis to staging and treatment options. Written not just for MOC but for all types of epithelial ovarian cancer, it is a helpful tool that’s easy to read.

• NCCN Downloable Guidelines

Research & Treatment

• Effects of Gastrointestinal-Type Chemotherapy in Women With Ovarian Mucinous Carcinoma: A retrospective study that reviews the outcomes for 52 women who received gastrointestinal-type chemotherapy versus a standard ovarian cancer regimen.

• More accurate diagnosis for rare ovarian cancer type on the cards, new research reveals: A great article on research that helped identify treatment markers for MOC, with hopes that further research can improve treatment options and patient outcomes.

• Does the primary site really matter? Profiling mucinous ovarian cancers of uncertain primary origin (MO-CUP) to personalise treatment and inform the design of clinical trials: This study looks at the genetic profiles of MOC and discusses the role targeted therapies may play in improving outcomes.

•HIPEC seen as cutting-edge treatment for some cancer patients

Tools, Podcasts and Videos 

•A Guide to CA-125 Levels: If you need help understanding what the CA-125 blood test is, and what the results mean, this is a great tool to download.

Online Peer Communities 

The support of others who are walking a similar path offers numerous benefits. An online peer community may be the answer.
