Adult- and pediatric-type GIST have different causes and respond differently to treatments.
Additionally, the convergence of these findings suggest that extra diligence be taken with "young adults" as pediatric-type GIST may present well beyond adolescence, particularly as these distinct sub-types have different causes, and consequently respond differently to treatments.
Additionally, these findings suggest that extra diligence be taken with "young adults" (aged 18-35 at diagnosis) as pediatric-type GIST may present well beyond adolescence, particularly as these distinct sub-types have different causes, and consequently respond differently to treatments.
Though both can be serious, the two forms of the disease differ somewhat in the symptoms they present (see Part 1) and have different causes.
Researchers disagree about whether it is one disease or a collection of symptoms that may have different causes in different patients.
Several Web sites assemble air safety data, mostly by airplane type and by airline, although the statistics should be read with a skeptical eye since events that seem close in location or timing may have different causes.
Although the diseases have different causes (like worms, flukes or parasites) and are spread by different vectors (like sandflies, tsetse flies or drinking water), some drugs that work against one will work against others.
The reason drugs work in some people but not in others is often because the same set of symptoms can have different causes.Sometimes, as in the case of AML and ALL, genuinely different diseases are involved.
