Cancer

Biography

I am committed to providing my patients complete medical care that takes into account their physical and emotional wellbeing. When I approach my patients, I think of them as a whole, a person behind the story. I enjoy and cherish this special relationship and I always strive to give my patients the best care.

I believe that knowledge is power; I want my patients to be informed when they make decisions that involve their care and their lives. I achieve that by discussing the patient's case with the patient's referring oncologist and by consulting with my colleagues at Wilmot Cancer Center or at other institutions.

I am a firm believer that physician-patient trust is important to deliver effective and complete medical care. This trust develops based on the patient's own experience dealing with their medical team. My goal is to work closely with our medical team to help our patients deal with their illnesses.

My goal in choosing a career in treating cancer patients is to "make a difference" in their lives. I do that not only by doing my best to take care of my patients, but also by researching new ways to help our patients. Our current treatments are not optimal and certainly can be improved to help our patients have better outcomes, which is my ultimate goal in my research career.

Research

Dr. Aljitawi's laboratory is primarily focused on studying the human hematopoietic stem cells and their interaction with their microenvironment. He utilizes this knowledge in studying translational research concepts that apply to patient care. Dr. Aljitawi's work has involved umbilical cord blood stem cells, Wharton's jelly mesenchymal stromal cells, Wharton's jelly matrix, and bone marrow mesenchymal stem cells. Dr. Aljitawi's main projects are:

1.Studying umbilical cord blood (UCB) CD34+ cell interaction with erythropoietin (EPO) as a soluble factor in UCB CD34+ microenvironment. Dr. Aljitawi has been investigating EPO signaling through EPO receptor (EPOR) effects on UCB CD34+ cell homing and engraftment. Dr. Aljitawi and his research team discovered that exposure to erythropoietin impairs UCB CD34+ cell homing to the bone marrow. To translate this finding to patient care, Dr. Aljitawi and his research team investigated the use of hyperbaric oxygen (HBO) as a modality to lower systemic EPO with the aim of improving UCB CD34+ cell homing and engraftment. This work in its entirety was recently published in Blood.

2. Developing in vitro 3D leukemia and myeloma models for chemotherapy drug testing: Dr. Aljitawi's lab has developed a 3D stromal-based co-culture model to grow leukemia and myeloma cells with stromal cells and used it to test the sensitivity of these cancer cells to chemotherapy. More recently, his lab has focused on studying decellularized Wharton's jelly matrix to create an extracellular matrix-based model to test leukemia cell responses to chemotherapy.

3. Studying the interactions between Wharton's jelly mesenchymal stromal cells and Wharton's jelly decellularized matrix for tissue regenerative medicine applications. Dr. Aljitawi's has been studying decellularized Wharton's jelly matrix as a scaffolding material for tissue regenerative applications, including wound and bone healing.

Clinical Trials

Multicenter safety study of unlicensed, investigational cryopreserved cord blood units (CBUs) manufactured by National Cord Blood Program (NCBP) and provided for unrelated hematopoietic stem cell transplantation of pediatric and adult patients

Lead Researcher: Omar S Aljitawi

The purpose of this study is to document and evaluate all problems that may occur with the use of investigational cord blood units. This study will evaluate the safety of administration of the investigational cord blood units by carefully documenting all infusion-related problems. The cord blood units in this study have been collected, processed, tested and stored by the National Cord Blood Program and meet the criteria for transplantation as approved by NetCord-FACT (Foundation for the Accreditation of Cellular Therapy).

Phase II Hyperbaric Oxygen in Improving Engraftment in Umbilical Cord Blood Stem Cell Transplantation

Lead Researcher: Omar S Aljitawi

The UCB transplant is a type of stem cell transplant used to treat cancer of the blood or lymph glands. The UCB transplant has advantages over other types of transplants such as ease of obtaining the umbilical cord blood, absence of donor risks, reduced risks of contagious infections, and the availability for immediate use. The UCB transplant is also associated with a lower incidence of graft versus host disease, or GvHD (in GvHD, the transplanted graft attacks the recipient organs).

A Randomized Phase II Study Evaluating the Efficacy of Hyperbaric Oxygen in Improving Blood Count Recovery in Autologous Hematopoietic Stem/Progenitor Cell Transplantation for Multiple Myeloma

Lead Researcher: Omar S Aljitawi

Patients with Multiple Myeloma who are considered for high-dose therapy and autologous transplantation at the bone marrow transplant clinic at the Wilmot Cancer Institute (WCI) will be be approached to participate in this trial. Eligible patients who choose to participate will be randomized so that half receive one hyperbaric oxygen therapy session prior to hematopoetic stem cell infusion and half will not. All subjects will have their blood counts monitored closely and time to count recovery will be compared between the two groups.
