Clinical Scorecard: Analysis of Radiotherapy and Chemotherapy's Impact on Cerebral Volume in Oncology Patients: A Study on Brain Tumors

At a Glance

CategoryDetail
ConditionPrimary and metastatic brain tumors including gliomas, meningiomas, and metastatic lesions
Key MechanismsUncontrolled proliferation of abnormal brain cells; tumor growth causing cerebral edema and neurological deficits; treatment effects from radiotherapy and chemotherapy on brain volume
Target PopulationAdult patients aged 18–90 years diagnosed with intracranial masses undergoing radiotherapy and/or chemotherapy
Care SettingMedical oncology departments with multidisciplinary management including surgical, radiotherapy, and chemotherapy interventions

Key Highlights

  • Brain tumors cause neurological and cognitive symptoms depending on tumor type, size, and location.
  • Radiotherapy and chemotherapy are critical adjuvant treatments, especially for aggressive tumors like glioblastoma multiforme.
  • Volumetric MRI assessments using tools like VolBrain and MRICloud enable objective measurement of brain and tumor volumes pre- and post-treatment.

Guideline-Based Recommendations

Diagnosis

  • Use conventional MRI sequences for anatomical tumor evaluation and diagnosis.
  • Perform volumetric measurements of brain structures and tumor volumes using validated software tools.
  • Histological classification per WHO criteria is essential for treatment planning and prognosis.

Management

  • Surgical resection is attempted when feasible to remove tumors.
  • Adjuvant radiotherapy with median doses around 60 Gy in 30–33 fractions is standard.
  • Chemotherapy is combined with radiotherapy for aggressive tumors to enhance treatment efficacy.
  • Follow-up MRI every 3 to 6 months for the first five years, then annually.

Monitoring & Follow-up

  • Regular MRI imaging to assess tumor response and cerebral volume changes.
  • Use of volumetric tools to objectively track brain structure changes during and after treatment.

Risks

  • Exposure to ionizing radiation is a known environmental risk factor for brain tumors.
  • Radiotherapy and chemotherapy may impact cerebral volume and brain structures, necessitating careful dose planning.

Patient & Prescribing Data

47 patients (11 females, 36 males) with primary or metastatic brain tumors treated with radiotherapy and/or chemotherapy

Median radiotherapy dose was 60 Gy over 30–33 fractions; 19 patients received whole brain irradiation at 40 Gy; treatment planning involved 3D dose distribution calculations.

Clinical Best Practices

  • Adopt a multidisciplinary approach integrating surgery, radiotherapy, and chemotherapy for brain tumor management.
  • Utilize advanced imaging and volumetric analysis tools for individualized treatment planning and monitoring.
  • Ensure ethical approval and retrospective data review for clinical studies involving imaging and treatment outcomes.
  • Tailor follow-up imaging schedules to tumor type and treatment response to optimize patient care.
