After surgery for gallbladder or bile duct cancer, some people are advised to undergo a further course of chemotherapy to lower the chance of the cancer coming back. This is called adjuvant chemotherapy. While many imagine chemotherapy only as an intravenous drip, certain treatments for biliary cancers come as tablets taken by mouth at home on a set schedule. One of the most common is capecitabine, widely known by the brand name Xeloda.
Capecitabine is converted inside the body into its active cancer-fighting form. It is usually taken twice a day, within about 30 minutes after breakfast and dinner, swallowed whole with water, and given in repeating cycles of several days on followed by several days off. The exact dose and schedule are set by the care team based on body surface area, kidney function, and overall condition, so it is important not to split, skip, or double up on tablets on your own.
Common effects during treatment include hand-foot syndrome (redness, burning, and cracking of the palms and soles), diarrhea, mouth sores, nausea, and fatigue. Hand and foot symptoms often ease with frequent use of moisturizer and by avoiding friction and heat, such as very hot water, long walking, and tight shoes. If diarrhea becomes frequent, replacing fluids helps, but if it is heavy or persistent it is safer to tell the care team first rather than simply adding more anti-diarrheal medicine on your own.
This can be especially tricky for older adults or for anyone having another operation or procedure (for example, cataract surgery) around the same time, when overlapping schedules and changing energy levels make pills easy to miss. It helps to mark start and stop dates on a calendar and to agree in advance on when to call the hospital rather than wait for the next appointment — for instance, fever of 38°C or higher, severe diarrhea, mouth inflammation that makes it hard to open the mouth, or hand and foot pain that disrupts daily life.
The goal of adjuvant chemotherapy is not to shrink a visible tumor but to reduce the risk of recurrence from microscopic cancer cells that may remain after surgery. For that reason, completing the planned course steadily matters even if you do not feel a dramatic effect day to day, and it is worth remembering that when side effects are hard to bear, dose adjustment is often an option before stopping altogether.
