What's the Difference Between Pediatric and Adult ALL?
View next
Published on January 20, 2020
Key Takeaways
- ALL is more often diagnosed in young children.
- Patients between the ages of 15 or 18 through 39 can be treated with pediatric treatment regimens.
- A subset of ALL is Ph-like ALL. The genes found in this subset are more resistant to chemotherapy and are more prevalent in the adolescent and young adult population.
Acute lymphoblastic leukemia expert Dr. Shira Dinner, from Northwestern University, talks to Esther Schorr about the recommended treatment regimens for pediatric and adult patients, and what new therapies are in development. Watch to learn more about how different patient subsets of ALL respond better to certain treatments.

Esther Schorr:
Hi there. This is Esther Schorr from Patient Power. I'm here at ASH 2019, and as you can see in the background there are like 25,000 hematologists, oncologists, researchers here talking about the latest in treatment for various hematological conditions.
I'm here today with Dr. Shira Dinner, who has lots of expertise related to ALL. She is from Northwestern University.
Dr. Dinner:
Yes, that's correct.
Esther Schorr:
So, Dr. Dinner, maybe we could start by talking a little bit about ALL and some of the things that you've been working on that have to do with the evolving treatments for ALL, and I know that our audience would be interested in differences between pediatric treatment and perhaps adults who are diagnosed with acute lymphocytic leukemia.
Dr. Dinner:
Of course. So more commonly acute lymphoblastic leukemia is diagnosed in children, and often they will receive more intensive chemotherapy regimens and tend to have more favorable survival outcomes. However, we are learning, especially looking at adolescents and some young adults with ALL, so patients between the ages of approximately 15 and 39 or 18 and 39 depending on how you're defining it, they can be treated with pediatric‑inspired intensive chemotherapy regimens, and this is improving their survival outcomes.
So this is where we're going in terms of the recommended standards for treating patients. Recently, within the last year, Wendy Stock published in Blood the results of the CLGB 10403 trial which specifically looked at a pediatric‑inspired chemo regimen in an adolescent and young adult population, and those patients did have improve survival outcomes.
Esther Schorr:
So what's the implication there? So you have this middle group that are not young children, they're adolescents, young adults, how will that change their experience of treatment?
Dr. Dinner:
Well, it's a difficult group to deal with in general. It's a very difficult time of life to have to be faced with such as adverse event. They are just on the cusp of becoming very independent from their families, perhaps financial independence, social independence, and then to have that taken all away from them by having such a horrible diagnosis is very difficult.
There also seems to be something biologically different about their disease. They don't tend to do as well as young children will. And we are learning about certain subsets of ALL called Ph‑like ALL that has certain gene mutations that seem to indicate that they do have a greater resistance to chemotherapy, and it seems more prevalent in this adolescent and young adult population than in children, so we are trying to use the intensified chemotherapy regimens for them. However, I think we still need to improve upon that.
