Uses of PD-1 Inhibitor Drugs

1. Treatment of Non-Small Cell Lung Cancer (NSCLC)

   • PD-1 inhibitors like pembrolizumab and nivolumab are widely used in treating NSCLC by enhancing the immune system’s ability to target and destroy cancer cells.

2. Management of Melanoma

   • These drugs help treat advanced melanoma by blocking the PD-1 pathway, allowing immune cells to attack melanoma tumors more effectively.

3. Therapy for Head and Neck Cancers

   • PD-1 inhibitors are approved for treating recurrent or metastatic head and neck squamous cell carcinoma, improving survival rates and reducing tumor progression.

4. Treatment of Hodgkin Lymphoma

   • PD-1 inhibitors are effective in treating relapsed or refractory classical Hodgkin lymphoma by boosting immune response against lymphoma cells.

5. Bladder Cancer Therapy

   • Patients with advanced or metastatic urothelial carcinoma benefit from PD-1 inhibitors when chemotherapy fails, offering an alternative treatment option.

6. Colorectal Cancer with MSI-H or dMMR

   • PD-1 inhibitors are used in treating metastatic colorectal cancer in patients with high microsatellite instability (MSI-H) or mismatch repair deficiency (dMMR).

7. Renal Cell Carcinoma (Kidney Cancer)

   • PD-1 inhibitors help slow the progression of advanced kidney cancer, often used alone or in combination with other targeted therapies.

8. Triple-Negative Breast Cancer (TNBC)

   • Certain PD-1 inhibitors are approved for treating advanced or metastatic TNBC in combination with chemotherapy, enhancing immune response against tumor cells.

9. Gastric and Esophageal Cancers

   • PD-1 inhibitors are used to treat advanced gastric and esophageal cancers, particularly in cases where standard treatments are ineffective.

10. Hepatocellular Carcinoma (Liver Cancer)

• These drugs provide an alternative treatment for patients with liver cancer who do not respond well to traditional therapies, improving survival rates.
