Cancer/Oncology Services

A Team Approach to Cancer Treatment

Anyone who has heard the words “you have cancer”, knows that your world changes at that point. Things can get confusing – patients and family members alike – sometimes don’t know what to do. That’s why CRMC provides individualized assistance to patients, families, and caregivers to navigate them through appropriate cancer care. We help you make educated decisions about your care – and our navigators help you through every step of the way.

Cancer Treatment Services is a point of pride here at CRMC. We are the only healthcare system in this region to offer both radiation oncology and medical oncology under one roof. We have an expert team of physicians – from oncologists and primary care, to general surgeons and gynecologists – who work together to understand your unique diagnosis and needs. We use nationally recognized cancer treatment protocols that are used in larger institutions – right here at home. And that means you can focus your time and energy on getting well. Our multi-disciplinary team is here for you – working together every day to provide you the best possible cancer care.


Nathan Uy, MD | Radiation Oncologist

Dr. Uy (U-ee),grew up in Coffeyville. His father, Dr. Wilson O. Uy, served as the Pathologist at CRMC for 25 years. Since 2012, Dr. Uy travels from Tulsa to see patients on a weekly basis in the Jerry Marquette Radiation Oncology Center.

“I wanted my hometown to have the highest level of cancer care available,” said Uy. “My roots in the community and at the hospital made it easy for me to commit to CRMC wholeheartedly.”

Akin Ogundipe, MD | Medical Oncologist Hematology

Dr. Ogundipe (O-gun-di-pay) or simply Dr. O, as many of his patients call him, has been coming to CRMC since 2005 from Ponca City, Oklahoma where his practice is based. He sees patients in the Tatman Cancer Center on a weekly basis.

“It was during my medical training that I became fascinated with blood disorders and cancer. I chose CRMC as a satellite clinic for my practice because I was impressed by the dedication of the staff to the community.”

Vicky Portwood, MSN | Director of Cancer Treatment Services & Outpatient Services

Vicky has worked at CRMC for over 30 years with most of her career spent in oncology. She currently oversees the operations of the Cancer Program that includes the Tatman Cancer Center (medical oncology – for patients who receive chemotherapy), the Jerry Marquette Radiation Oncology Center, and the outpatient clinics including the Pacemaker Clinic.

“Lots of people think oncology would not be a good place to work as the outcomes are not always rosy,” said Vicky. “However, the work is very rewarding. I enjoy the opportunity to help people when they need it most, and my patients are very appreciative of my assistance. I help those that are unable to afford medications to get patient assistance, and I try to improve the life they have to live.”
