Matthew P. Greenwood is a Hematologist-Oncologist who works with blood cancers and blood-related conditions. Based in Sydney, he is affiliated with St Vincent's Hospital Sydney and UNSW Sydney. He also works alongside teams at the St Vincent's Centre For Applied Medical Research, where care and research sit close together.
He helps look after people with illnesses that affect the blood, bone marrow, and lymph system. This can include leukaemia and lymphoma, both slow-growing and faster forms. He also treats conditions where the immune system and blood cells don’t work in the usual way, such as thrombocytopenia (low platelets) and other related problems.
A big part of his work is caring for patients who need bone marrow transplant treatment. After a transplant, some people can develop graft versus host disease (GvHD). In those cases, his role is to help manage symptoms and support recovery, which can include mouth ulcers and skin or gut issues. At times, there are also added infection risks, including cytomegalovirus (CMV) and other viral problems, so careful follow-up matters.
He also supports people who have ongoing chest and breathing issues that can happen after serious illness, including bronchitis and bronchiolitis obliterans. Some patients may deal with dry mouth, dry eyes, or inflammation linked to autoimmune conditions like Sjogren syndrome and rheumatoid arthritis. Others may be managing complications from cancer treatment, or symptoms that come up alongside illnesses such as COVID-19, pneumonia, or mononucleosis.
Over time, specialist care in this area means working as part of a wider team. People often need help with both the main condition and the day-to-day side effects. That might include managing pain, adjusting treatment plans, and checking lab results often, especially when things are moving quickly.
Matthew also stays connected to current medical research through the research-focused setting at St Vincent's. In some cases, patients may be considered for clinical trial options if they are suitable. That can be helpful when standard treatments are not enough, or when there are new approaches under study.
Overall, his focus is practical and patient-centred: clear plans, close monitoring, and steady support for people dealing with complex blood and immune conditions.
