• Myelodysplastic Syndromes (MDS): A group of diverse bone marrow disorders in which the bone marrow does not produce enough healthy, mature blood cells.
• Acute Myeloid Leukemia (AML): A rapidly progressing cancer of the blood and bone marrow affecting myeloid cells.

Benign Hematologic (Non-Cancerous Blood) Disorders Managed

• Iron Deficiency Anemia: A common type of anemia caused by insufficient iron, leading to reduced red blood cell production and oxygen-carrying capacity.
• Hemolytic Anemia (e.g., Autoimmune Hemolytic Anemia - AIHA): A disorder in which red blood cells are destroyed faster than the bone marrow can produce them.
• Von Willebrand Disease & Other Inherited Bleeding Disorders: Genetic conditions that impair the blood's ability to clot effectively, causing prolonged or excessive bleeding.

This list provides examples of common conditions treated and is not exhaustive. Cancer and blood disorders are complex, and treatment is highly individualized. For personalized advice, please discuss your specific situation with Dr. Arthur Sullivan or your referring physician.

• Immune Thrombocytopenia (ITP) & Other Platelet Disorders Management: Investigating and managing low platelet counts due to immune or other causes.
• Peripheral Blood Smear Review & Advanced Cytomorphology: Expert microscopic examination of blood cells to identify abnormalities and aid in diagnosis.
• Autologous & Allogeneic Stem Cell Transplant Consultation, Coordination & Post-Transplant Care (as part of a transplant team or referral network): Evaluating eligibility for, coordinating referrals to, and providing follow-up care for patients undergoing stem cell transplantation for hematologic malignancies.
• Management of Myelodysplastic Syndromes (MDS): Diagnosis and treatment of bone marrow failure disorders, including supportive care, growth factors, and disease-modifying therapies.
• Neutropenia & Other White Blood Cell Disorders Evaluation: Investigating and managing low or abnormal white blood cell counts, increasing susceptibility to infections.

Medically necessary consultations, diagnostic tests (like biopsies, imaging reviews), chemotherapy, immunotherapy, targeted therapies, radiation therapy planning and delivery, and management of blood disorders by a licensed Hematologist such as Dr. Sullivan are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor or another specialist is in place. Specific drug coverage for newer therapies can vary by provincial formularies and may require special authorization. It's always recommended to discuss coverage specifics with Ontario Health Insurance Plan (OHIP), Dr. Sullivan's office, the hospital's patient financial services, or the cancer care navigation services at the treatment facility.

Do I need a referral to see Dr. Sullivan, an Hematologist?

Yes, a referral from your family physician or another specialist is almost always required to see an Hematologist like Dr. Sullivan for assessment or treatment of cancer or significant hematological conditions. This ensures that your primary care provider is involved in your care continuum and that you are directed to the most appropriate specialist for your specific situation. Cancer care programs often have centralized intake systems that manage referrals to ensure timely access.

How is cancer care typically coordinated when seeing Dr. Sullivan?

Cancer care and complex hematology care often involve a multidisciplinary team (MDT) of specialists working together. This team may include medical oncologists like Dr. Sullivan, surgeons, radiation oncologists, pathologists, radiologists, specialized oncology nurses, pharmacists, social workers, dietitians, genetic counselors, and palliative care specialists. Regular team meetings (often called tumor boards or MDT meetings) usually occur to discuss individual patient cases and develop comprehensive, coordinated treatment plans. Dr. Sullivan works collaboratively within this team to ensure you receive holistic and well-managed care.

How will treatment decisions be made for my condition by Dr. Sullivan?

Treatment decisions in oncology and hematology are highly personalized and made collaboratively. Dr. Sullivan will consider many factors, including the type and stage of your cancer or blood disorder, your overall health, genetic markers of the disease (if applicable), current treatment guidelines, and importantly, your personal preferences and values. Often, cases are discussed in multidisciplinary team meetings (tumor boards) with other specialists to ensure a comprehensive approach. You will be an active participant in this decision-making process.

Does a Hematologist only treat blood cancers?

No, Hematologists treat a wide range of blood disorders, not just cancers. This includes benign (non-cancerous) conditions such as various types of anemia (e.g., iron deficiency anemia, vitamin B12 deficiency, sickle cell anemia, thalassemia), bleeding disorders (like hemophilia or von Willebrand disease), clotting disorders (thrombophilia, deep vein thrombosis, pulmonary embolism), and issues with white blood cells (like neutropenia) or platelets (like ITP). Dr. Sullivan, if focused on hematology, can diagnose and manage these conditions.

What is immunotherapy and how does it work for cancer?

Immunotherapy is a type of cancer treatment that helps your own immune system fight cancer. It works by boosting or changing how the immune system works so it can find and attack cancer cells more effectively. There are different types of immunotherapy, including checkpoint inhibitors, CAR T-cell therapy, and cancer vaccines. Dr. Sullivan may recommend immunotherapy if it's an appropriate option for your type of cancer and will explain how it works and what to expect.

How does cancer or blood disorder treatment differ for children compared to adults?

[IF PROVIDER IS PEDIATRIC SPECIALIST:] As a Pediatric Hematologist/Oncologist, Dr. Sullivan specializes in these differences. Children's bodies react differently to treatments, and the types of cancers and blood disorders are often distinct from adult conditions. Treatment protocols are specifically designed for pediatric patients, considering their growth and development. Care is family-centered, involving parents and caregivers closely in decision-making and support. [ELSE:] Treatment for children with cancer or blood disorders is highly specialized and managed by Pediatric Hematologists/Oncologists. They use protocols tailored to children, considering long-term effects on growth and development.
