SEER is an authoritative source of information on cancer incidence and survival in the United States. SEER currently collects and publishes cancer incidence and survival data from population-based cancer registries covering approximately 28 percent of the U.S. population.
(This code is effective for cases diagnosed 2010 and later. For cases diagnosed prior to 2010 see codes: 9728/3 [lymphoma] or 9836/3 [leukemia].)
The presenting features are generally similar to those of other patients with ALL. Cases of T-ALL should not be included in this code even though those patients have near tetraploid karyotypes.
Immunophenotyping will confirm that the patient has a B-lymphoblastic B-ALL; the genetic testing provides the information needed to classify this neoplasm as a B lymphoblasticleukemia/lymphoma with hyperdiploidy.
