Applications of PD-1 Inhibitor Drugs

1. Cancer Immunotherapy

   • PD-1 inhibitors are primarily used in cancer immunotherapy, helping the immune system recognize and attack cancer cells. They are effective for treating various cancers, including lung, melanoma, and head and neck cancers.

2. Non-Small Cell Lung Cancer (NSCLC)

   • PD-1 inhibitors, such as pembrolizumab and nivolumab, are applied in treating advanced or metastatic non-small cell lung cancer, improving survival and reducing tumor growth.

3. Melanoma Treatment

   • These drugs are widely used for treating advanced melanoma, particularly in cases where surgery and chemotherapy are ineffective, by boosting the immune response against the tumor.

4. Hodgkin Lymphoma

   • PD-1 inhibitors are applied in the treatment of classical Hodgkin lymphoma, particularly for patients with relapsed or refractory disease, significantly improving patient outcomes.

5. Head and Neck Squamous Cell Carcinoma (HNSCC)

   • They are used to treat recurrent or metastatic head and neck cancers, offering an alternative to traditional chemotherapy and increasing survival rates.

6. Bladder Cancer

   • PD-1 inhibitors are effective in treating advanced bladder cancer, particularly in patients who have failed chemotherapy, by stimulating the immune system to target cancer cells.

7. Gastric and Esophageal Cancer

   • These inhibitors are applied in treating advanced gastric and esophageal cancers, improving the immune response and offering hope for patients with limited treatment options.

8. Renal Cell Carcinoma (Kidney Cancer)

   • PD-1 inhibitors are used in treating advanced kidney cancer, either alone or in combination with other therapies, to enhance immune system activity against tumor cells.

9. Colorectal Cancer

   • PD-1 inhibitors are applied in cases of colorectal cancer that are microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR), offering a more personalized treatment option.

10. Triple-Negative Breast Cancer (TNBC)

• In combination with chemotherapy, PD-1 inhibitors are applied to treat advanced triple-negative breast cancer, particularly in patients with limited therapeutic options.

11. Hepatocellular Carcinoma (Liver Cancer)

• PD-1 inhibitors are increasingly being used to treat advanced liver cancer, particularly in patients who have not responded to traditional treatments, improving the prognosis for these patients.

12. Combination with Other Cancer Treatments

• PD-1 inhibitors are often used in combination with other therapies, such as chemotherapy, targeted therapy, or other immunotherapies, to enhance treatment efficacy and offer better outcomes for patients with advanced cancers.
