Hematocrit to Hemoglobin Ratio and Red Blood Cell Distribution Width in Polycythemia Vera and Secondary Erythrocytosis.
Egypt100 participantsStarted 2022-12-15
Plain-language summary
Polycythemia vera (PV), a hematological neoplasm characterized by excessive erythropoiesis due to Janus kinase 2 (JAK2)- activating mutations. On the other hand, patients with secondary polycythemia (SP), a disorder mostly caused by an increased red cell mass due to chronic hypoxia (i.e, pulmonary disorders and smoking) and erythropoietin-producing tumors (such as leiomyoma, hemangiomas, renal cysts and various carcinomas), are phenotypically slightly different and are usually considered to have significantly better outcomes.
Red blood cell distribution width (RDW) reflects the heterogeneity of red blood cell sizes (anisocytosis) and is routinely reported as a part of complete blood count by automated instruments in hematology laboratories.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* All patients aged 18 years and older who were newly diagnosed to have polycythemia vera between September 2014 and November 2022 at Sohag university hospital, department of internal medicine, hematology unit and hematology outpatient clinic.
Exclusion Criteria:
* Patients were excluded if: (1) their disease was not newly diagnosed, (2) their disease met WHO criteria for chronic, acute myeloid leukemia or other myeloid neoplasms.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
