Choroid Plexus Carcinoma: A Rare and Aggressive Brain Cancer

Choroid plexus carcinoma (CPC) is a rare and highly aggressive malignant type of brain cancer that primarily affects children under the age of 2 [1, 14]. It is considered one of the most severe forms of choroid plexus tumors, with a much poorer prognosis compared to other grades of choroid plexus tumors [2].

Characteristics

CPCs are fast-growing tumors that originate in the choroid plexus of the brain, which produces cerebrospinal fluid (CSF

Common Signs and Symptoms of Choroid Plexus Carcinoma

Choroid plexus carcinoma, a rare type of brain cancer that primarily affects children, can exhibit various symptoms depending on the tumor's size, location, and grade. Here are some common signs and symptoms associated with choroid plexus carcinoma:

• Headaches: Pressure headaches, particularly in the morning or evening, may be one of the first symptoms of choroid plexus carcinoma [3][4].
• Hydrocephalus: Increased pressure within the skull due to the production of too much cerebrospinal fluid (CSF) or blockage of its normal flow can lead to hydrocephalus. Signs and symptoms of hydrocephalus may include:
  • Nausea
  • Vomiting
  • Irritability
  • Confusion
  • Enlarged fontanelles in infants [5][6]
• Increased intracranial pressure: Symptoms related to increased intracranial pressure, such as headache, nausea, vomiting, and irritability, are common in choroid plexus tumors [7][8].
• Vision problems: Double vision or blurred vision may occur due to the tumor's impact on the brain's visual centers [9].
• Seizures: Seizures can be a symptom of choroid plexus carcinoma, particularly if the tumor is located in an area that affects seizure control [10][11].

It's essential to note that these symptoms can vary depending on the individual child and the specific characteristics of their tumor. If you suspect your child may have choroid plexus carcinoma, consult a qualified healthcare professional for proper diagnosis and treatment.

Diagnostic Tests for Choroid Plexus Carcinoma

Choroid plexus carcinoma diagnosis involves a combination of physical and neurological exams, imaging studies, lumbar puncture, and biopsy to confirm the presence of the tumor. Here are some of the diagnostic tests used:

• Physical Exam: A thorough physical examination is conducted to assess overall health and identify any potential symptoms related to the tumor.
• Neurological Function Test: This test evaluates reflexes, muscle strength, eye and mouth movement, coordination, and alertness to determine which part of the brain may be affected by the tumor. [2][5][12][13]
• Imaging Studies: Imaging tests such as MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans are used to visualize the tumor's location, size, and extent. An MRI scan can reveal irregular borders and a cauliflower-like appearance of the tumor. [8]
• Lumbar Puncture: A lumbar puncture may be performed to collect cerebrospinal fluid for analysis.
• Biopsy: A biopsy is performed to diagnose CPT (Choroid Plexus Tumor). In a biopsy, a small sample of the tumor is removed during surgery using a needle. A pathologist looks at the tissue sample under a microscope to identify the specific type of tumor. [10]

These diagnostic tests help doctors confirm the presence of choroid plexus carcinoma and determine its grade and type, which is essential for developing an effective treatment plan.

Treatment Options for Choroid Plexus Carcinoma

Choroid plexus carcinoma (CPC) is a rare and aggressive brain tumor that primarily affects children. While surgery is the most common form of treatment, drug therapy plays a crucial role in managing this condition.

Chemotherapy

Chemotherapy uses medications to kill cancer cells. It may be used in addition to surgery and radiation therapy to help control the growth of CPC (2). The ifosfamide, carboplatin, and etoposide (ICE) regimen has been successfully used for CPC in young children, including those with recurrent or metastatic disease (6).

Targeted Therapy

Targeted therapy drugs target genetic changes that cause cancer cells to grow. While not specifically approved for CPC, targeted therapies may be explored as potential treatment options.

Immunotherapy

Immunotherapy involves using medications to help the immune system find and destroy cancer cells. This approach is still being researched for CPC but holds promise for future treatment strategies.

Clinical Trials

Clinical trials test new treatments, such as chemotherapy, targeted therapy, or immunotherapy drugs (4). These studies can provide valuable information on the effectiveness of various drug therapies in treating CPC.

Key Findings

• Etoposide was associated with a high response rate among patients treated for CPC (5).
• The ICE regimen has shown promise in treating young children with CPC (6).

In summary, while surgery is the primary treatment for choroid plexus carcinoma, chemotherapy and other drug therapies play important roles in managing this condition. Further research into targeted therapy and immunotherapy may lead to new treatment options.

The differential diagnosis of choroid plexus carcinoma (CPC) involves distinguishing it from other types of brain tumors. According to various medical sources, the following conditions are considered in the differential diagnosis of CPC:

• Ependymoma: A type of brain tumor that arises from the ependymal cells lining the ventricles and central canal of the spinal cord. Ependymomas can be differentiated from CPC based on their location, histological features, and immunohistochemical markers such as e-cadherin positivity in CPC [4].
• Primitive neuroectodermal tumor (PNET): A type of brain tumor that arises from primitive neural cells. PNETs can be aggressive and may resemble CPC in radiology, but they can be differentiated based on their histological features and immunohistochemical markers [11].
• High-grade glioma: A type of brain tumor that arises from glial cells. High-grade gliomas can be aggressive and may resemble CPC in radiology, but they can be differentiated based on their histological features and immunohistochemical markers.
• Metastatic carcinoma: A type of cancer that has spread to the brain from another part of the body. Metastatic carcinomas can be differentiated from CPC based on their location, histological features, and immunohistochemical markers [13].

It's worth noting that the differential diagnosis of CPC can be challenging, and a thorough evaluation by a neuropathologist is often necessary to confirm the diagnosis.
