For patients with neuroblastoma, diagnosis is primarily through the symptoms, signs, detailed physical examinations, medical history inquiries, and most importantly, radiological data, which includes CT scans or MRI of the head. Definitive diagnosis requires surgical removal of the tumor. A small amount of tumor tissue is retained after excision and used for pathological examination to confirm the diagnosis. Neuroblastoma is categorized as an epithelial-like malignant tumor, indicative of a high degree of malignancy. In most cases, early in the disease, the tumor adheres to surrounding tissues, which greatly complicates complete surgical removal, and most patients have a poor prognosis.

How to diagnose neuroblastoma?

For neuroblastoma, the final diagnosis requires the patient to undergo surgical treatment. During the surgery, the neuroblastoma is completely excised, and a small amount of tumor tissue is retained for pathological sectioning. The diagnosis is determined based on the results of the pathological examination, which assesses the specific cells of the neuroblastoma, whether it is benign or malignant, and its level of malignancy. This also determines how the patient will receive subsequent treatments like radiotherapy and chemotherapy. In addition to relying on pathological examinations, most neuroblastoma patients can also undergo more thorough examinations. In most cases, elevated levels of catecholamines and their metabolites can be found in the blood or urine of neuroblastoma patients, significantly higher than that of the normal population.

neuroblastoma cure rate

Neuroblastoma is relatively likely to be a malignant tumor, typically characterized by rapid growth of malignant tumors.In the early stages of the disease, it often adheres to surrounding tissues, making it difficult to completely remove through surgery. Even with surgical treatment, the outcomes are generally modest, and recurrence is likely to occur shortly after surgery. Once recurrence occurs, the malignancy of the tumor will continue to increase.For these patients, the prognosis is poor. It is generally recommended to undergo surgical treatment early, followed by radiotherapy and chemotherapy to potentially extend the patient's lifespan, but it is usually difficult to cure.

Symptoms of Neuroblastoma

Typical symptoms of neuroblastoma include anemia and fatigue, excitement, no weight gain or weight loss, or irregular fever. The initial symptoms in the course of a short disease are not typical. Early diagnosis is difficult. Nonspecific symptoms include fatigue, loss of appetite, fever, joint pain. Those occurring within the skull display a bit of central nervous system cursing symptoms and symptoms of intracranial hypertension. Main manifestation. Occurrence outside the skull depends on the location of the tumor and the metastatic sites. Involvement of the thoracic cavity can cause chest and back pain and difficulty breathing, involvement of the abdominal cavity is characterized by abdominal distension, constipation, dysentery, and involvement of the spinal canal manifests as reduced strength in the trunk and limbs, and motor and sensory disturbances.

Neuroblastoma treatment

Neuroblastoma is relatively considered a malignant tumor, and its growth rate is quite rapid. It often adheres to surrounding tissues in the early stages, which makes it very difficult to completely remove surgically. However, even so, it is still advisable to opt for surgical treatment once neuroblastoma is detected. The tumor should be completely removed surgically, and a small amount of tumor tissue should be retained for pathological examination after removal. Based on the results of the pathological examination, it will be determined whether additional treatments such as radiotherapy or chemotherapy are needed. Furthermore, since some neuroblastomas are sensitive to radiotherapy, it is recommended to promptly take the patient to a local hospital for treatment after surgery.

Early symptoms of neuroblastoma

For neuroblastoma, in the early stages of the disease, mild headaches, dizziness, nausea, and vomiting often occur, but the symptoms are relatively mild and most can be tolerated. As the disease gradually progresses and the tumor volume begins to increase, it compresses the surrounding brain tissue and cranial nerves, causing the patient to exhibit certain degrees of headache, dizziness, nausea, vomiting, and other clinical manifestations. As the tumor volume further increases and cerebral edema becomes apparent with elevated intracranial pressure, it may lead to cranial nerve dysfunction in patients. For instance, it might trigger epileptic seizures or cause patients to experience hemiplegia, aphasia, and other clinical manifestations. Once these symptoms occur, it is advisable to visit a local hospital early for treatment.
