Dr. Pitney studies how various factors affect children's health during treatment for acute lymphoblastic leukemia (ALL), a common type of leukemia in children. His work examines how obesity impacts survival rates, changes in body size during chemotherapy, and specific side effects of cancer drugs. Additionally, he investigates how certain medications can be safely used in children with complex health conditions, like neurofibromatosis type 1.
Key findings
In a study of 307 children undergoing ALL treatment, their BMI increased during the first two years but decreased slightly by the end, indicating a need for tailored support for young cancer patients.
Research on 322 Hispanic children showed that obesity at diagnosis did not significantly affect survival rates or cancer-free outcomes, suggesting obesity may be less concerning in this context.
In a Phase I trial with the drug tipifarnib for children with tough solid tumors, the highest safe dose was determined to be 200 mg/m2, showing it can be well tolerated with manageable side effects.
A study found that 11% of 155 Hispanic children with ALL experienced hyperglycemia, highlighting the need for careful monitoring of blood sugar levels during chemotherapy.
141 Hispanic children with ALL experienced steady BMI increases during the first year of treatment, particularly those who were normal weight at diagnosis, suggesting a risk of long-term weight gain.
Frequently asked questions
Does Dr. Pitney study complications related to obesity in children?
Yes, Dr. Pitney researches how obesity affects treatment outcomes in children with acute lymphoblastic leukemia.
What treatments has Dr. Pitney researched?
He has studied drug therapies like tipifarnib, evaluating their safety and effectiveness in children with difficult cancer cases.
Is Dr. Pitney's work relevant to Hispanic children with leukemia?
Yes, many of his studies specifically focus on Hispanic children, addressing health issues prevalent in this population during leukemia treatment.
What should we know about body size changes during leukemia treatment?
Dr. Pitney's studies show that children undergoing treatment for leukemia often experience significant changes in body size, which could impact their health and treatment.
How does chemotherapy affect blood sugar in children?
His research indicates that some children may develop high blood sugar during chemotherapy, particularly if they are older or heavier, which necessitates careful monitoring.

Demographic correlates of body size changes in children undergoing treatment for acute lymphoblastic leukemia.
2007
Pediatric blood & cancer
Baillargeon J, Langevin AM, Lewis M, Estrada J, Grady JJ +3 more
Plain English This study looked at how body size changes in children being treated for acute lymphoblastic leukemia (ALL) over time. Researchers followed 307 children and found that while their body mass index (BMI) increased during the first two years of chemotherapy, it slightly decreased at the end of treatment. Specifically, children aged 2-9 started with a lower BMI than older kids (ages 10-18) and stayed lower throughout their treatment. Understanding these patterns is important for developing tailored support for young cancer patients.
Who this helps: This benefits patients and their doctors by providing insights into weight management during cancer treatment.
Phase I trial and pharmacokinetic study of the farnesyltransferase inhibitor tipifarnib in children with refractory solid tumors or neurofibromatosis type I and plexiform neurofibromas.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology
Widemann BC, Salzer WL, Arceci RJ, Blaney SM, Fox E +8 more
Plain English This study tested a drug called tipifarnib in children with tough-to-treat solid tumors and a genetic condition known as neurofibromatosis type 1. Researchers found that the highest safe dose for these kids was 200 mg/m2, and the drug was well tolerated, with children experiencing side effects like nausea and rash but no long-term toxicity even after multiple treatment cycles. This matters because it shows that tipifarnib can be safely given to children, potentially providing a new treatment option for difficult cases.
Who this helps: This helps children with refractory solid tumors and neurofibromatosis type 1.
Obesity and survival in a cohort of predominantly Hispanic children with acute lymphoblastic leukemia.
2006
Journal of pediatric hematology/oncology
Baillargeon J, Langevin AM, Lewis M, Estrada J, Mullins J +4 more
Plain English Researchers studied how obesity at the time of diagnosis affects the survival of 322 predominantly Hispanic children with acute lymphoblastic leukemia (ALL). They found that being obese did not lower overall survival rates or the chances of staying cancer-free after treatment. Specifically, the risk of decreased survival related to obesity was not significant in any age group, indicating that obesity may not be as concerning in this context as previously thought.
Who this helps: This information benefits pediatric cancer patients and their doctors by providing clarity on the impact of obesity in treatment outcomes for ALL.
Transient hyperglycemia in Hispanic children with acute lymphoblastic leukemia.
2005
Pediatric blood & cancer
Baillargeon J, Langevin AM, Mullins J, Ferry RJ, DeAngulo G +4 more
Plain English This study focused on 155 Hispanic children with acute lymphoblastic leukemia (ALL) to find out how many experienced high blood sugar (hyperglycemia) during the start of their chemotherapy. It found that 11% of these children developed hyperglycemia, with older age and higher body weight increasing the risk. This research highlights the importance of monitoring blood sugar in these patients, especially since obesity is common in this group.
Who this helps: This helps doctors and healthcare providers better manage and support Hispanic children undergoing chemotherapy for leukemia.
Therapy-related changes in body size in Hispanic children with acute lymphoblastic leukemia.

Plain English This study looked at how the body size of Hispanic children with a type of leukemia called acute lymphoblastic leukemia (ALL) changed during their treatment. Researchers followed 141 children and found that their body mass index (BMI) increased steadily during the first year of chemotherapy and remained higher throughout treatment, especially for those who were normal weight at diagnosis. This is important because it shows that these patients are at risk for gaining weight due to their treatment, which can affect their long-term health.
Who this helps: This information is useful for doctors treating young patients with leukemia.
