Iressa for Lung Cancer: Understanding Its Role in Targeted Therapy

What are Iressa 250mg Tablets?

Iressa 250mg tablet is a prescription drug that has Gefitinib as its active ingredient and is approved by the US Food and Drug Administration. This drug offers a targeted therapy to treat metastatic, non-small cell cancer by inhibiting a protein that helps cancer cells to grow, known as epidermal growth factor receptor(EGFR). It belongs to a class of drugs called antineoplastics that shrinks the tumors frequently and slows down the growth of cancer cells, which makes it a more effective method of treatment as compared to traditional chemotherapy, enhancing survival rate and quality of life.

Understanding the Role of Iressa in Targeted Therapy

Iressa is a targeted therapy designed to treat advanced and metastatic non-small cell lung cancer in patients with EGFR gene mutations. Iressa works at the molecular level. It focuses on the Epidermal Growth Factor Receptor (EGFR). In patients with specific EGFR mutations, this receptor is overactive, compelling tumor cells to grow and divide. In targeted therapy, Iressa blocks the tyrosine kinase enzyme within EGFR. With this mechanism, the chemical signals that tell cancer cells to grow, survive, and spread to other parts of the body are stopped.

What Other Treatments are Used for Lung Cancer?

Surgery: Lung cancer can generally spread from the original tumor to multiple spots within the lung. Surgery is an option in such cases. It is basically the best way to treat non-small-cell lung cancer. Your healthcare expert will remove the part of the lung that has a tumor and the tissue around it.

Chemotherapy: In chemotherapy, medications are administered to destroy cancer cells. Chemotherapy may be administered before or after surgery, combined with radiation therapy, or used as the primary treatment if surgery is not possible. A single drug or a combination of drugs may be selected based on the cancer type and its proliferation rate.

Immunotherapy: Immunotherapy uses drugs to enhance your immune system to recognize and eliminate cancer cells. It is typically recommended for patients with high PD-L1 expression and may be combined with chemotherapy.

Targeted Therapy: Targeted therapy is designed to inhibit the slow growth or spread of the cancer. Cancer cells require molecules to survive and spread; these molecules are made by the genes that cause cancer. Targeted therapies interfere with or target those molecules or the cancer-causing genes that create them. Targeted therapy can also be used with surgery or radiation therapy as part of a treatment plan to cure lung cancer.

Radiation Therapy: This therapy treats cancer by using high-energy beams to kill cancer cells. It works for both non-small-cell and small-cell-lung cancers. You receive radiation treatments for a few days at a time over several weeks. It may be administered before surgery to shrink a tumor and facilitate removal, or after surgery to eliminate any remaining cancer cells. Some people have it along with chemotherapy.
