Neuroblastoma is a highly malignant epithelial neurocyte tissue tumor, which is relatively aggressive. Often in the early stages of the disease, the tumor tissue adheres to surrounding brain tissue, nerves, and blood vessels, making it impossible to completely remove it surgically. The residual tumor cells quickly recur over time. As a result, most neuroblastoma patients have a poor prognosis and short survival time, even with effective surgical treatment, including postoperative radiotherapy and chemotherapy. Therefore, it is recommended that those diagnosed with neuroblastoma undergo early further examinations and treatments.

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.

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.

How to check for neuroblastoma?

For the examination of neuroblastoma, we generally recommend a neurological examination to help determine whether there are any clear positive signs, as well as to inquire about medical history and family history to judge if there are any cases of neuroblastoma among family members. Additionally, detailed laboratory tests, routine blood tests, routine urine tests, and biochemical tests, including tumor-related diagnostics, can help in making assessments. Of course, the most accurate and crucial examinations are CT or MRI scans of the head. If necessary, an enhanced MRI scan of the head can be conducted to further evaluate the location, nature, severity of the tumor, and its relationship with the surrounding neural and vascular tissues, which helps provide a basis for further surgical treatment.

Early symptoms of neuroblastoma

For patients with neuroblastoma, the early stages of the disease often manifest as mild headaches, dizziness, nausea, and vomiting. The symptoms are relatively mild and can be significantly alleviated by taking oral pain relief medications. Therefore, the condition often does not receive adequate attention, leading to missed diagnoses. As the tumor size increases, the original symptoms such as headaches and dizziness will significantly worsen. Some patients may even experience optic nerve atrophy, papilledema, reduced visual fields, and vision deficits. When such conditions occur, patients often undergo cranial CT or MRI scans to confirm the presence of neuroblastoma.

Neuroblastoma is divided into several types.

Neuroblastoma can be classified into several types, such as abdominal neuroblastoma, which often presents with obvious abdominal distention. Patients may experience difficulty defecating, dry stools, and stubborn constipation. Thoracic neuroblastoma mainly presents with obvious difficulty in breathing, accompanied by shortness of breath, frequent breathing, and low blood oxygen saturation. Spinal neuroblastoma primarily causes a noticeable decrease in trunk and limb strength, with most patients experiencing significant limb motor dysfunction and difficulty walking.
