About this study

Official title: Neutrophil Extracellular Traps (NETs) Formation Following Chemotherapy for Pediatric Hematological and Solid Tumors, and Its Relation to Other Neutrophil Functions and the Role of NETs in Antitumor Activity

Examine neutrophil extracellular traps (NETs) formation, in relation to other neutrophil functions like chemotaxis, superoxide production, hydrogen peroxide production, and the presence of myeloperoxidase, in pediatric patients undergoing chemotherpy for solid and hematological malignancies. This data could shed new light on the mechanism responsible for the increased susceptibility to infection among these patients and aid in improving their prophylactic antimicrobial treatment.

NETs formation against tumor cell lines and their ability to kill tumor cells will also be examined. The finding of NETs activity against tumor cells could have a major contribution to the investigators understanding of the function of the immune system against cancer.

Read the detailed description

Neutrophil function, including NETs formation, chemotaxis, superoxide production, hydrogen peroxide production, and the presence of myeloperoxidase, will be examined in 50 pediatric patientsundergoing chemotherapy for solid and hematological malignancies. Children with the following malignancies will be examined: acute lymphoblastic leukemia,acute myelogenous leukemia,Hodgkin's lymphoma,non-Hodgkin's lymphoma, primary bone sarcoma,rhabdomyosarcoma,non-rhabdomyosarcoma,neuroblastoma,Wilms' tumor,hepatoblastoma or hepatocellular carcinoma,germ cell tumors, and hystiocytosis. Also those with brain tumors such as medulloblastom,low grade glioma,high grade glioma,ependymoma,and embryonal and pineal region tumors. Data gathered on the patients will include background data (age, gender, ethnicity) and background diseases, data on current illness (histologic type, grade, stage, response treatment,infectious episodes), and on the use of ranulocyte-colony stimulating factor (G-CSF).

The following time points will be examined:

  1. At diagnosis, before initiation of chemotherapy.
  2. immediately before the 2nd course.
  3. After the middle course.
  4. A month after the last course.
  5. Three months after the last course.
  6. In acute myelogenous leukemia and acute lymphoblastic leukemia,time points also include the middle of the maintenance course and 3 months after the end of maintenance.

An additional blood examination will be used to examine NETs formation against tumor cell lines and their ability to kill tumor cells.

Questions about this trial

What is this clinical trial studying?

An observational study of Pediatric Solid Malignancies and Pediatric Hematological Malignancies, run by Tel-Aviv Sourasky Medical Center at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 15 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Sivan Achituv, MD (972-527360718, sivanbrg@netvision.net.il), or a site near the patient. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2012.
