In clinical practice, although calcification is a relatively favorable phenomenon, the overall condition of neuroblastoma does not change significantly because of it. Therefore, it is still not a good sign. For neuroblastoma, whether calcification occurs or not, it remains a form of tumor. Only through early surgical treatment can the problem be fundamentally resolved, otherwise, there is a tendency for recurrence and metastasis to occur later on. Moreover, it is important to note that regardless of whether the tumor calcifies, its nature does not change. Only fundamental treatment can bring better hope, so calcification does not lead to very good outcomes.

How is neuroblastoma diagnosed?

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.

Symptoms of neuroblastoma recurrence

For neuroblastoma, when the tumor recurs, the patient's original symptoms such as headaches, dizziness, nausea, and vomiting will reappear, occurring intermittently and worsening persistently. Most patients will experience significant increased intracranial pressure, and even frequent nausea and vomiting. Additionally, some neuroblastoma patients experience severe vertigo, especially when changing body positions, where the vertigo is particularly pronounced. For such patients, when the above symptoms and signs occur, they should go to a local hospital as soon as possible for a reassessment using cranial MRI to monitor changes in their condition.

Is neuroblastoma serious?

Neuroblastoma is relatively serious and is classified as a highly malignant tumor, one of the epithelial cell tumors. The disease often leads to severe intracranial pressure increases, manifesting as intense headaches, dizziness, nausea, vomiting, and even possible optic disc edema, vision loss, and visual field defects. The occurrence of neuroblastoma often indicates a poor prognosis for patients, with a short disease duration and reduced survival time. The five-year survival rate is decreased. Treatment primarily involves surgical intervention to completely remove the neuroblastoma, followed by postoperative radiotherapy, chemotherapy, and other related treatments.

How do you get neuroblastoma?

Currently, there is no consensus on the specific causes of neuroblastoma. In most cases, it is believed to be caused by the failure of primitive myeloid epithelial cells to continue differentiating, which is somewhat linked to congenital genetic factors. Additionally, poor lifestyle choices and exposure to certain chemical carcinogens, including long-term exposure to radiation, can potentially lead to neuroblastoma. Neuroblastoma is a highly malignant tumor that generally grows and develops rapidly. It often adheres to surrounding tissues in the early stages of the disease, making complete surgical removal quite difficult, and typically has a poor prognosis.

Neuroblastoma examination items

For neuroblastoma, the examination items mainly include the patient's vital signs and physical examination, including detailed examinations to observe if there are any obvious pathological signs. Additionally, it is necessary to inquire about the patient’s medical history, especially past medical history and family history. Main examination items include laboratory tests, routine blood and urine tests, biochemistry, and tumor-related tests. Furthermore, examinations also involve using a cranial CT scan, MRI of the head, and if necessary, an enhanced MRI scan of the head, to further determine the presence of neuroblastoma, as well as its location, quantity, and the relationship between the surrounding tissues, blood vessels, and nerves.
