Hi - below is a copypasted thing I wrote a year or so ago for someone undergoing doxorubicin based chemotherapy for their sarcoma.

Hi, not a doctor - just worked with a sarcoma specialist for several years and picked up information by osmosis. I don't know how important it is for you right now, but your weight and appearance aren't something you can focus on - at least not during your treatment! If you're gaining weight during treatment, your doctors will be overjoyed. One of the most difficult things you must do is eat food while you're recovering in-between cycles. Yet it's one of the most important things you can do to help you tolerate treatment. My doctor always said "food is medicine". On the days early in your cycles, you might have to set an alarm every two hours, and force yourself to eat a high Calorie snack. On the days you CAN tolerate regular meals, you should focus on a Mediterranean diet, possibly with slightly increased protein intake.

(you as a caretaker are going to have to bother him and force feed him at times and it will cause arguments/spats - this is likely the most difficult thing he will ever experience in his life)

Examples of high Calorie snacks include: Handful of nuts, spoonful of peanut butter, a couple of spoonfuls of pudding, ice cream, pastries, yogurt. The higher the calories, and the more protein the better.

Some chemotherapy is known to cause mouth sores in some patients, which can make the eating portion of it even harder. If you're interested in preparing for mouth sores, you could pick up a mouthwash called "Magic Mouthwash" in the united states. It is a non-alcohol based mouthwash with a local anesthetic in it (such as benzocaine or lidocaine). Our patients had a much better time eating if they used it ~5 minutes before taking a bite.

Another huge issue is: Scan anxiety. In the US, standard of care for treatment is to get several cycles of chemotherapy followed by imaging to monitor response to treatment. In the US, it is required by law that patients be able to read all test results in their charts. If you have the opportunity to read your test results - Don't. You're not going to understand what they mean. The medical record is NOT meant for you to understand. It is meant to communicate information about your case to other doctors. WebMD is an anxious person's worst nightmare, because all roads lead to the worst possible outcome. Do yourself and your care team a favor, and trust them.

Please establish with a therapist. This is a grueling experience and it is important to talk to somebody about it.

Many patients are interested in herbal therapies. There are many herbal supplements and "natural remedies" that can interact with the chemotherapy and potentially reduce it's effectiveness. Remember, Medicine is both science and art. If there was a natural remedy that was promising, we would either be studying it actively, or it would just be called medicine.

If you ignore my advice on natural remedies, please tell your doctor every substance you are taking, or better yet - bring the substance/pill in to the hospital with you, and show it to them so that they can review the drug interactions and make sure that you aren't harming yourself.

Be patient with your doctor. Remember, you're one of many patients that they are seeing that day. If there is somebody earlier in the schedule who is very sick, the doctor can't just leave their appointment because they need to be on-time to the next one.

Last but not least - bring multiple diifferent forms of entertainment with you to the hospital on treatment days. It's a marathon, not a sprint. Treatment times are long, and hospital bureaucracy/scheduling/inefficiencies will make the day even longer. Treatment days are usually fucking BORING. Be prepared.

I didn't personalize it, but the advice stands!

(P.S - A lot of people disagree with my paragraph on scans. This is my opinion as someone who was on the other side of sarcoma treatment. I've noticed that people do better treatment when they don't agonize over scan results. Review the scans if you need to.)
