Marion Liu, MD
We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

Get to Know Me
I am a surgeon who treats people for stomach (gastric) cancer and soft tissue sarcomas such as gastrointestinal stromal tumors (GIST). I see patients at Memorial Hospital and Rockefeller Outpatient Pavilion in New York City and Memorial Sloan Kettering Monmouth in New Jersey.
As a surgeon, I aim to not just surgically remove the cancer but to take care of my patients and their families to the best of my ability. I want my patients to understand their diagnosis and treatment options so we can make decisions together about the best plan of action. In addition to surgery, these treatments may include chemotherapy, radiation, or even new treatments offered through clinical trials. I work closely with a team of medical oncologists, radiation oncologists, and pathologists to design a comprehensive and personalized plan for each patient.
Surgery plays a key role in the treatment of stomach cancer. When possible, I offer minimally invasive robotic surgery to remove the tumor and the surrounding lymph nodes. This technology can enhance recovery, but my priority will always be to offer the best option to each patient. In some cases, stomach surgery can alter how you eat and digest food. Our team of specialty trained nurses and nutritionists can help you adjust to eating after stomach surgery. My goal is not just to cure cancer but to optimize the quality of life of my patients.
In addition to treating patients with stomach cancer, I also study stomach cancer in the lab. We use mouse models to understand how stomach cancer develops and find novel ways to treat it. As much as possible, we build these models using the genomic characteristics that we observe in our patients, so they can closely represent the cancers that we are treating. Our goal is to take what we discover in the lab and translate it to clinical practice through clinical trials.
As a surgeon-scientist, I like to ask questions that challenge our understanding of cancer. I hope my patients will also ask me questions and challenge me to improve our treatment of stomach cancer.
I'm a surgeon, which is a doctor with special training in many types of surgery.

Disclosures
Members of the MSK Community often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community. These activities outside of MSK further our mission, provide productive collaborations, and promote the practical application of scientific discoveries.
MSK requires doctors, faculty members, and leaders to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public. Not all disclosed interests and relationships present conflicts of interest. MSK reviews all disclosed interests and relationships to assess whether a conflict of interest exists and whether formal COI management is needed.
