Below is a detailed overview of the standard treatment modalities for this specific type of brain tumor.

Surgical Intervention

Resection

Surgical resection is often the first line of treatment for accessible tumors located in the cerebral ventricle. The goal is to remove as much of the tumor as possible while preserving surrounding brain tissue. This can help alleviate symptoms caused by increased intracranial pressure or obstruction of cerebrospinal fluid (CSF) flow. The extent of resection can significantly influence prognosis, with more extensive removal generally associated with better outcomes[1].

Biopsy

In cases where the tumor is in a location that is difficult to access or when the tumor's nature is uncertain, a biopsy may be performed. This procedure allows for histological examination to confirm the diagnosis and guide further treatment decisions[1].

Radiation Therapy

External Beam Radiation Therapy (EBRT)

Radiation therapy is commonly used post-surgery to target residual tumor cells and reduce the risk of recurrence. EBRT can be particularly effective in treating malignant tumors, as it helps to control local disease and manage symptoms[2].

Tumor Treating Fields (TTF)

An emerging treatment modality for glioblastoma, which can also be relevant for tumors in the cerebral ventricle, is Tumor Treating Fields therapy. This non-invasive treatment uses electric fields to disrupt cancer cell division, potentially improving survival rates when used in conjunction with other therapies[3].

Chemotherapy

Systemic Chemotherapy

Chemotherapy may be indicated, especially for high-grade tumors. Agents such as temozolomide are commonly used in conjunction with radiation therapy. The combination of chemotherapy and radiation has been shown to improve overall survival in patients with malignant brain tumors[4].

Targeted Therapy

In some cases, targeted therapies may be considered based on the tumor's molecular characteristics. These therapies aim to specifically target cancer cells while sparing normal cells, potentially leading to fewer side effects and improved efficacy[4].

Supportive Care

Symptom Management

Supportive care is crucial in managing symptoms associated with malignant neoplasms of the cerebral ventricle. This may include medications to control seizures, manage pain, and alleviate symptoms of increased intracranial pressure. Palliative care services can also be integrated to enhance the quality of life for patients facing advanced disease[5].

Conclusion

The treatment of malignant neoplasms of the cerebral ventricle (ICD-10 code C71.5) requires a comprehensive approach tailored to the individual patient's needs. Surgical resection, radiation therapy, and chemotherapy are the cornerstone treatments, often used in combination to optimize outcomes. Ongoing research into novel therapies, including targeted treatments and Tumor Treating Fields, continues to evolve the landscape of care for these challenging tumors. As always, treatment decisions should be made collaboratively by a multidisciplinary team, considering the patient's overall health, tumor characteristics, and personal preferences.
