1) Squamous cell carcinoma: Found in the lining of the bronchial tubes, it's the most common type of NSCLC and is the most common type of lung cancer in men.
2) Adenocarcinoma: The most common type of lung cancer in women and among nonsmokers. It affects the glands of the lungs that produce mucus.
3) Bronchioalveolar carcinoma: A rare type of adenocarcinoma. 4) Large-cell undifferentiated carcinoma: A rapid-growing cancer that forms near the outer edges of the lungs.
These four types are grouped together because they are treated the same way. Small cell lung cancer is different in that it grows rapidly and can spread quickly throughout the body. It is almost always caused by cigarette smoking and responds well to chemotherapy and radiation therapy.
VACCINE PROTECTION: A novel cancer vaccine called Lucanix is being tested in patients with non-small cell lung cancer who have completed several rounds of chemotherapy. The goal is to improve patient survival by programming the body to fight off any remaining cancer cells. It contains lung cancer cells that have been genetically modified so they don't produce the protein TGF-beta, which suppresses the immune system. "Every day, every person develops cancer cells in their body and it's a job of the immune system to find those cancer cells, catch them and kill them; but something happens to your immune system where it fails to do so," Lyudmila Bazhenova, M.D., a medical oncologist and hematologist at the University of California, San Diego Morse Cancer Center, explained to Ivanhoe. The modified cells are injected into a patient with the hope that their body's immune system starts killing them and then continues to kill the other cancer cells already in the body.
In a phase II clinical study, the one-year survival rate of patients was 61 percent and the two-year survival rate was 41 percent. Normally, only 30 percent of patients survive past the first year after chemotherapy. Experts say the drug has virtually no side effects. A phase III clinical trial is currently taking place and is involving 700 patients at about 90 centers across the world. Patients are given injections once a month for 18 months, followed by two quarterly injections.
