All of the following are treatment modalities in malignant mesothelioma except
**Malignant Mesothelioma Treatment Modalities**
**Core Concept**
Malignant mesothelioma is a rare and aggressive cancer primarily affecting the pleura or peritoneum, often associated with asbestos exposure. Treatment modalities aim to control symptoms, prolong survival, and improve quality of life.
**Why the Correct Answer is Right**
Treatment options for malignant mesothelioma include surgery, chemotherapy, and radiotherapy. Surgical interventions, such as pleurectomy or extrapleural pneumonectomy, aim to remove tumors and affected tissues. Chemotherapy, using agents like pemetrexed and cisplatin, targets rapidly dividing cancer cells. Radiotherapy involves delivering high-energy radiation to destroy cancer cells.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because **gene therapy** is not a standard treatment modality for malignant mesothelioma. Gene therapy involves using genes to prevent or treat diseases, which is not a widely accepted approach for this cancer type.
**Option B:** This option is incorrect because **immunotherapy** is being explored as a potential treatment option for malignant mesothelioma, but it is not a widely established modality. Immunotherapy involves stimulating the immune system to attack cancer cells.
**Option C:** This option is incorrect because **targeted therapy** is not a standard treatment modality for malignant mesothelioma. Targeted therapy involves using drugs or other substances to specifically target cancer cells.
**Clinical Pearl / High-Yield Fact**
Malignant mesothelioma is often associated with asbestos exposure, and a thorough occupational history is essential in diagnosing this cancer.
**Correct Answer:** A. Gene therapy is not a standard treatment modality for malignant mesothelioma.
