Hello Welcome to HCM
Sorry to hear about condition of your husband. He seems to have advanced disease which has spread to many organs. It is good thing that he has responded to first line chemotherapy
because his disease in lung and urethra
is clear. He was started in second line chemotherapy with taxol because liver lesion was not responding. The CAT scan will give you answer regarding what is response of taxol in liver.
Apart from that it is equally important for him to be free from pain.Patients like him who have advanced stage disease need good palliative care
.It is treatment of problems patient is facing like pain ,nausea
,vomitting etc. This treatment is more important to improve quality of life of patient. There are many different pain medicine available and doctor can presribe him appropriate medication in adequate dose so that he becomes pain free.
Please discuss with your oncologist
or palliative care specialist regarding this.
