What is the life expectancy of a 78 year old, stage 4 colon cancer spread to liver and lungs? having chemotherapy (tablets) but losing weight.

Survival ?: Stage 4 colon Ca spread to liver and lungs have a poor prognosis unless the degree of liver involvement is small and only a few lung lesions present. The lung lesions can be removed with a thorascope leaving only the liver as the site of spread. Here microwave ablation, chemo embolization or radiolabelled microspheres can then be used. There are several immunotherapy protocols available.

Life expectancy: At 78, with stage IV colon cancer, the survival is about 4-6 months without treatment. With the new treatments combining chemo with biological drugs, survival times are in the range of 24-30 months. With a less aggressive treatment I estimate an AVERAGE survival of 9-12 months. Keep in mind these estimates are just a ball park figure, keep things one month at a time.
