In high-risk disease, chances of long-term survival, however, are less than 40%, despite aggressive treatment. [5] Neuroblastoma is the most common cancer in babies and the third-most common cancer in children after leukemia and brain cancer. [5] About one in every 7,000 children is affected at some time. [2]
Targeted molecular therapy for neuroblastoma involves treatment aimed at molecular targets that have a unique expression in this form of cancer. Neuroblastoma, the second most common pediatric malignant tumor, often involves treatment through intensive chemotherapy. A number of molecular targets have been identified for the treatment of high ...
The median age for the diagnosis of neuroblastoma is 22 months, being rare in adolescence and adulthood but showing poor prognosis when it does present in those age groups. The degree of differentiation of neuroblastoma is correlated to the prognosis, with a wide variety of outcomes (from tumor regression to recurrence and mortality).
The tumor will then need to be biopsied to confirm the diagnosis. After the diagnosis of a CNS PNET is confirmed, management includes neoadjuvant chemotherapy and radiation (to reduce tumor size burden), complete surgical resection with confirmed negative margins, and/or additional adjuvant post-surgical chemotherapy.

Genetic, [1] epigenetic, [2] proteomic, [3] glycomic, [4] and imaging biomarkers can be used for cancer diagnosis, prognosis, and epidemiology. Ideally, such biomarkers can be assayed in non-invasively collected biofluids like blood or serum. [5] Cancer is a disease that affects society at a world-wide level.
Because OMS is so rare and occurs at an average age of 19 months (6 to 36 months), a diagnosis can be slow. Some cases have been diagnosed as having been caused by a virus. After a diagnosis of OMS is made, an associated neuroblastoma is discovered in half of cases, with median delay of 3 months. [12] The interictal EEG pattern is usually ...
Reflect the stage of cancer; By determining the stage of cancer, it's possible to give a prognosis and treatment plan. [4] Screening for cancers; No screening test is wholly specific, and a high level of tumor marker can still be found in benign tumors. The only tumor marker currently used in screening is PSA (prostate-specific antigen ...
