Overview
Neuroblastoma is a malignant tumor that arises from neural crest cells, which are normally involved in the development of the sympathetic nervous system and adrenal glands.[1][2][3][4] In 1910, the term neuroblastoma was first used to describe the tumor by Dr. James Homer Wright, an American patholgist at Massachusetts General Hospital. Based on the degree of the cellular maturity and composition, neuroblastoma may be further classified into three subtypes according to the International Neuroblastoma Pathology Classification which include undifferentiated neruoblastoma, poorly differentiated neuroblastoma, and differentiating neuroblastoma.[5][6] Genes involved in the pathogenesis of neuroblastoma include NBPF10 gene, KIF1B gene, and ALK gene. Neuroblastoma is the most common extracranial solid cancer in childhood and the most common cancer in infancy. The staging of neuroblastoma is based on the International Neuroblastoma Staging System (INSS).[7][8] Symptoms of neuroblastoma include fever, abdominal distension, constipation, cough and weakness. A positive finding of a palpable abdominal mass, fever and purple skin patches is suggestive of neuroblastoma. On labrotary studies an elevated levels of blood and urinary catecholamines, vanillylmandelic acid (VMA), and homovanillic acid (HVA) are suggestive of neuroblastoma. CT scan is the investigation of choice for the diagnosis of neuroblastoma.[8] On CT scan, neuroblastoma is characterized by a heterogeneous, calcified, and necrotic mass, that may encase the surrounding vessels or invade the surrounding tissues. The definitive diagnosis of nueroblastoma is confirmed by a biopsy. Children Oncology Group (COG) risk stratification system determines the protocol of management used for neuroblastoma patients. Low risk neuroblastoma patients are usually managed with either observation or surgical resection of the tumor. Intermidiate risk neuroblastoma patients are usually managed with neoadjuvant chemotherapy in advance of a definitive surgical resection. Whereas high risk neuroblastoma patients are usually managed with a combination of surgery, chemotherapy, radiation therapy, hematopoietic stem cell transplantation, differentiation therapy, and immunotherapy. Surgical intervention alone may be curative as a single therapeutic modality for the management of low risk neuroblastoma patients.[1][2][3][4]
Historical Perspective
In 1910, the term neuroblastoma was first used to describe the tumor by Dr. James Homer Wright, an American patholgist at Massachusetts General Hospital.[1]
Classification
Neuroblastic tumors may be grouped according to International Neuroblastoma Pathology Classification (Shimada classification) into two groups which include a schwannian stroma rich group and a schwannian stroma poor group. Based on the degree of the cellular maturity and composition, neuroblastoma may be further classified into three subtypes according to the International Neuroblastoma Pathology Classification which include undifferentiated neruoblastoma, poorly differentiated neuroblastoma, and differentiating neuroblastoma.[2][5][6]
Pathophysiology
Neuroblastoma arises from neural crest cells, which are normally involved in the development of the sympathetic nervous system and adrenal glands. Neuroblastoma is frequently located along the sympathetic nervous system structures. Genes involved in the pathogenesis of neuroblastoma include NBPF10 gene, KIF1B gene, and ALK gene. Neuroblastoma is associated with a number of syndromes that include neurofibromatosis type 1, Beckwith-Wiedemann syndrome, and DiGeorge syndrome. On gross pathology, a well defined, bulky, and tan colored mass is a characteristic finding of neuroblastoma. On microscopic histopathological analysis the presence of round blue cells separated by thin fibrous septa are characteristic findings of neuroblastoma.[3][1][4]
Causes
There are no known direct causes for neuroblastoma.[1]
Differentiating Multiple Myeloma from other Diseases
Intra-abdominal neuroblastoma must be differentiated from other diseases that cause abdominal distention and constipation such as Wilms tumor and ganglioneuroma. Whereas intra-thoracic neuroblastoma must be differentiated from other diseases that cause shortness of breath and chronic cough such as intrathoracic lymphoma and extra lobar pulmonary sequestration.[3][1]
Epidemiology and Demographics
Neuroblastoma is the most common extracranial solid cancer in childhood and the most common cancer in infancy.[1] The overall incidence rate of neuroblastoma is approximately 4.9 per 1,000,000 individuals in the United States. The incidence of neuroblastoma decreases with age; the highest incidence is in the first year of life. Males are slightly more commonly affected with neuroblastoma than females. The male to female ratio is approximately 1.12 to 1. Neuroblastoma usually affects individuals of the Caucasian race. African American, Native Indian and Asian individuals are less likely to develop neuroblastoma.[9]
Risk Factors
There are no established risk factors for neuroblastoma.[1]
Screening
According to the the U.S. Preventive Service Task Force (USPSTF), there is insufficient evidence to recommend routine screening for neuroblastoma.[10]
Natural History, Complications and Prognosis
Neuroblastoma patients may initially present with vague symptoms making the diagnosis of such patients difficult. If left untreated, patients with neuroblastoma may progress to develop fatigue, loss of appetite, joint pain, and fever. Complications of neuroblastoma may include treatment-resistant diarrhea, Horner's syndrome, and transverse myelopathy. Depending on the extent of the tumor at the time of diagnosis, the prognosis may vary. However, the prognosis of neuroblastoma is generally regarded as poor.[3][1][4][2]
Diagnosis
Staging
The staging of neuroblastoma is based on the International Neuroblastoma Staging System (INSS). According to a newly proposed International Neuroblastoma Risk Group Staging System (INRGSS), there are four stages of neuroblastoma based on the extent of dissemination and image findings. According to the Children Oncology Group (COG) risk stratification system neuroblastoma patients are risk stratified into a low risk group, an intermediate risk group, and a high risk group based on the tumor INSS stage, the patient's age, tumor grade, and the amplification of MYCN gene.[1][7][8][4]
History and Symptoms
Symptoms of neuroblastoma include fever, abdominal distension, constipation, cough and weakness.[1][11][8]
Physical Examination
A positive finding of a palpable abdominal mass, fever and purple skin patches is suggestive of neuroblastoma.[1][11][4][8]
Laboratory Findings
An elevated levels of blood and urinary catecholamines, vanillylmandelic acid (VMA), and homovanillic acid (HVA) are suggestive of neuroblastoma.[4][1][8]
X Ray
On plain radiography neuroblastoma is characterized by an intraabdominal or intrathoracic soft tissue mass. Other findings of neuroblastoma on plain radiography include calcification and remodelling of surrounding bony structures.[3]
CT
CT scan is the investigation of choice for the diagnosis of neuroblastoma.[8] On CT scan, neuroblastoma is characterized by a heterogeneous, calcified, and necrotic mass, that may encase the surrounding vessels or invade the surrounding tissues.[3]
MRI
On a T1 weighted brain MRI image, neurblastoma is characterized by a hyperintense, heterogeneous, and necrotic mass.[3]
Echocardiography or Ultrasound
On ultrasound, neuroblastoma is characterized by a heterogeneous , vascular, and necrotic mass with localized areas of calcification.[3]
Other Imaging Findings
Other imaging studies for neuroblastoma include nuclear medicine studies such as fludeoxyglucose-18F positron emission tomography scan (18F-FDG PET) and metaiodobenzylguanidine (123I-MIBG) scintigraphy.[12]
Other Diagnostic Studies
The definitive diagnosis of nueroblastoma is confirmed by a biopsy. Charecterstic findings for neuroblastoma on microscopic histopathological analysis can be found here.[2]
Treatment
Medical Therapy
Children Oncology Group (COG) risk stratification system determines the protocol of management used for neuroblastoma patients. Low risk neuroblastoma patients are usually managed with either observation or surgical resection of the tumor. Intermidiate risk neuroblastoma patients are usually managed with neoadjuvant chemotherapy in advance of a definitive surgical resection. Whereas high risk neuroblastoma patients are usually managed with a combination of surgery, chemotherapy, radiation therapy, hematopoietic stem cell transplantation, differentiation therapy, and immunotherapy.[4]
Surgery
Surgical intervention alone may be curative as a single therapeutic modality for the management of low risk neuroblastoma patients.[4]
