NETs growing despite 3 months of capecitabine and temozolomide

Posted by djchambers @djchambers, Feb 4 10:37am

I've been on cap/temo for 3 months, with some very annoying side effects. Just got the results of CT scan. My two tumors have grown. My Louisville oncologist is suggesting standard chemo and having a port installed. He says without that I can expect 6 to 12 months before my tumors become terminal.
I have requested an appointment with Dr. Hobday at Mayo in Rochester whom I’ve seen before. I hope he will give me recommendation for best treatment. I have not heard back yet.

Interested in more discussions like this? Go to the Neuroendocrine Tumors (NETs) Support Group.

The tumor continued to grow despite the three rounds of oral cap/tem. That’s why they’ve gone to the folfox infusions.

I have yet to have a CT scan to see if the infusions have any impact on the tumors. Doctor says they want me on several months of infusions before they do a CT scan to see if it is working.

I was diagnosed two years ago. The primary was near my small intestine. The biopsy showed it a lower grade, but after surgery, it was determined to be a grade 3 well differentiated. This fall I was diagnosed with a reoccurrence. as a tumor near where the original site was as well as one in the liver. A liver biopsy confirmed again that it’s grade 3 well-differentiated.

I did three rounds of capicitaben and temlizide. I had a lot of G.I. symptoms, severe pain in my esophagus and colon spasms. Because of low blood counts, low platelets, first cycle low white blood count second cycle they reduced the democide in those cycles.

Now I’m on second cycle of fol fox. The neuropathy in my hands has been my primary complaint, although I have pain in my joints in particularly my jaw and thumbs.

I’ve just discovered from a bone scan that I have osteopenia. Previously, I had excellent bone health.

Do you know your dosage on CapTem? And what it was lowered to? The way my relative feels after 4 days off Capecitabine I doubt she will take again unless Dr can explain a lower dosage will decrease symptoms by x % or which ones. I hope these side effects are truly from the Capecitabine and not tumor growth ( PET scan mid Feb showed very low metabolic activity and feeling good up until end of last week toward end of cycle 1). Eating very little and still vomiting even with anti nausea meds.

I don’t know my dosage cap/tem. They did not reduce the Capucine Tata at all. It was the temo they reduced.

Dr. Hobday at Mayo said he kept was likely cause of GI problems. Not temo.

Chemo dosages are calculated based on weight and other factors they told me.

@tomrennie Can I ask you when you were diagnosed, what grade and where NET originated ( just re-read above and you stated pNET so started in Pancreas) and has it metastasized? You mentioned you were on CAPTEM for 13 rounds was this the first treatment? Also you state reduced dosage of capecitabine did you start at a higher level and Dr reduced due to side effects? What is your dosage? You are on 2.5 years what are side effects? My relative took 1 round of capecitabine 3000mg/day (after 12 rounds of Folfox) and side effects have been difficult — mouth sores, hand foot syndrome and rash on chest ( both of these have improved a little), abdominal cramps with nausea/vomiting and diarrhea, 8-9 lbs weight loss in 6 days, neuropathy in hands and feet (probably from Folfox although I don’t know if Capecitabine is making it worse since it keeps progressing vs getting better). Seeing Dr tomorrow, I doubt they will want to continue with this drug but maybe a lower dose would help or another regimen? What was the dosage when you were on CapTem (for both drugs)? I do not believe these are functional NETs so no real hormonal issues which a lot of the treatments work toward alleviating. Thank you

@briana311 I was diagnosed in 8/22, grade 2 pancreatic NET. It has spread primarily to my liver and bones. My first treatment was the 13 cycles of CAPTEM. I started with 3 500mg pills of capecitabine in the morning and 2 at night. I don't recall the mg dosage of the temozolomide. About halfway through the 13 cycles, the doctor reduced the morning dosage to 2 500mg pills to help with side effects. I am still on the 2 pills in the morning and 2 at night. I get some mouth sores, dry skin anywhere on my body including my hands and feet, fatigue, body aches and pains, and occasional diarrhea. They are all a lot less than they used to be. The bad stomach pains, nausea and vomiting mostly stopped about halfway through taking CAPTEM. I live with neuropathy in my lower legs, feet, and hands. I lost over 100 pounds prior to and during the first few months of CAPTEM. Did I miss anything that you asked?

I last saw my local before infusion last week. He said I looked healthy enough to have 2nd round.

I guess I’ll next see him before 3rd round which I’ve delayed by a week because I’m having family come for visit. And also hope to give me more time to recover.

The neuropathy was so bad by end of infusion I could barely walk. They kept me awhile to be sure I wasn’t having strike or allergic reaction. But it was just really painful and sudden neuropathy in hands and feet.
