What would the life expectancy of a stage 4 lung cancer patient be?

Limited. Personal, risk factors and cancer stage. If stage 4 with distant metastasis, then with best care 2-5 years is possible.
Stage 4 lung ca. Unfortunately many patients with lung cancer are diagnosed with "late stage" disease - either 3 or 4 - meaning it has spread outside the lungs. Fewer than 2% of stage 4 patients live 5 yrs. In fact, most with stage 4 will survive less than a year. At this stage, some patients elect to have chemo +/- radiation, but a lot of patients also elect palliative (comfort only) therapies.

What is the average life expectancy for patients diagnosed with non small cell lung cancer stage 4?

Very low-5% 5 yr. . Stage IV non-small cell lung cancer is metastasis to any site other than lung, like brain. This has a very low 5 year survival of 5% or less. Very few (about 20%) have localized dissease at diagnosis. Read more...

Lung cancer. There are many factors involved, such as the stage of cancer, wether it is treatable with surgery or chemotherapy, the condition of the patient, age of the patient. Read more...
Can be high. Small size, peripheral, squamous cell can be cured. 70-90% at five years depends on cell type- small cell cancer is still a bad actor. Many variables better to answer with cell type- biopsy and imaging= staging to look for any distant mets. Read more...

What can we expect from a stage 4 lung cancer patient with bone metastases- what can be done in case all treatments are ruled out?

Biomarkers in lungCA. For stage 4 non-small cell lung cancer -- specifically adenocarincoma -- i would check the biomarkers alk and egfr. The response rate with oral drugs for those targets is ~80% vs. 20% with chemo. Bone mets can be treated with bisphosphonate (zometa) or Denosumab (xgeva). Palliative care provided early has a survival benefit. Ref: temel et al. Nejm http://www.Nejm.Org/doi/pdf/10.1056/nejmoa1000678. Read more...

If a stage four lung cancer patient is spread to the bones, would having a bone marrow transplant increase the likelihood of survival?

No. Unfortunately, metastatic lung cancer is incurable. Neither chemotherapy, nor radiation, nor bone bone marrow transplants can ofter a cure. Chemotherapy may prolong survival in some patients and radiation is used to treat pain resulting from bone involvement. Bone marrow transplants are never used to treat this condition. Read more...
No. Bone marrow transplant would not treat the primary tumor and would be ineffective. A bone marrow transplant would introduce such high risks that it would most likely hasten the patient's demise. Read more...
