A lot: The updated long term results of rtog 9410 were published in 2011 in the journal of the national cancer institute. This study examined different regimens of radiation and chemotherapy in patients with stage iii lung cancer. They found that patients lived longer if they received chemotherapy and radiation at the same time as opposed to sequentially.

A lot: This stage is not resectable. If a patient has a good performance status chemo and radiation is use in hopes of curing the disease. Even if the cancer is not cured and progresses the idea is to slow it down. The patient may also have pain, bleeding or cough and these symptoms will improve because of treatment.

Goal is cure.: If complete staging (pet and MRI brain) show no metastases, then treatment depends on why iiib - either b/c tumor is T4 or nodes are n3. If no nodes, and t4, may consider lower dose chemort followed by surgery. If n3, then full dose chemort alone. Unfortunately while goal is cure, only achieved in 20%. Get evaluated at an academic center for clinical trials, as many improvements being made!

It can shrink: The tumor. But is inferior to chemoradiotherapy. Surgery in iii-b does have anecdotes from selected case, but the treatment is chemoradiotherapy with intent to cure. Cure may be as high as 30%. Best wishes.

Yes: High-energy x-rays are the most common. Usually generated by the linear accelerator. It can be given over 6- 7 weeks daily for a curitive intent, 2-3 weeks for palliation, 3-5 fraction using radiosurgery linear accelator base or cyberknife radiosurgery for cure. Other forms of radiation are protons, high dose rate brachytherapy. These are less often used.

Dr. Reza Shirazi

Yes: We often use radiation in this setting for palliation of symptoms, like palliation of pain from a bone metastesis or to open up an airway etc.. The mainstay of treatment for stage IV lung cancer is chemotherapy.

A 45-year-old member asked:

Is it unusual for the radiation therapy for lung cancer to make someone lose his voice?

2 doctor answers10 doctors weighed in
Dr. Bahman Daneshfar
Radiation Oncology 33 years experience
Yes: The vocal cords when treated directly could cause this so in lung cancer thats not likely. However the left vocal cord has a nerve that goes down in the chest then comes back up to the cord. There may be cancer in the mediastinum that is compressing this nerve leading to the hoarseness. Radiation by itself in the usual fractioned (6 week) course shouldn't. With cyberknife it may happen.
