@mmiles04, I wanted to check in and see how you and your husband are doing. I noticed that you mentioned palliative care. Palliative care is offered for symptom management. Being offered palliative care doesn't equate death sentence or giving up. Stage 4 by definition may not be curable, but people can live well for many years with advanced incurable cancer. By the same token, I also understand when a patient may decide that the treatment is too much and negatively affects quality of life. It can also help at that point to look into hospice care.

Getting back on topic: Great tip from @lionsfan to consider physical therapy. Was he able to get a consult with a physical therapist? How is your husband's back pain?
