Peripheral T Cell Lymphoma

If his age or overall health is a reason, I could understand this. CHOP by itself is rarely used against any T-Cell Lymphoma (excepting ALCL/ALK+) since T-Cell Lymphomas do not respond well to it. Some do not respond at all. Normally, Etoposide is added to improve effectiveness, making the combination into CHOEP, or EPOCH. I would hope that they will scan very early for response. If response is not as expected, there are far less toxic single agent drugs to try - but FDA regulations require that he must fail primary therapy first. Romidepsin (Istodax), Pralatrexate (Folotyn), Belinostat (Beleodaq) and perhaps even Nivolumab (Opdivo) can be tried. As well, there are two new drug regimens (TREC and BGV) that might be considered. 

Have a look at the T-Cell Leukemia/Lymphoma Foundation's website, as there is a gold mine of information there, including facilities and hematologists who specialize in T-Cell Lymphomas. These lymphomas are unlike any other cancer and unlike any other lymphoma and requier precise expertise.

As well, here is a YouTube playlist of Dr. Andrei Shustov presenting patient education infomation regarding T-Cell Lymphomas.

My 64-year-old husband is currently being treated for PTCL Stage 4 at Dana Farber in Boston.  He is in a drug trial using Duvelisib (trial drug) in conjunction with Romidepsin.  They originally gave him 3 treatments of E-CHOP, but it was not particularly effective, so they stopped it.  He was on Duvelisib alone for 6 weeks as a pill to see if it would put him into remission on its own, which it did not, but it was partially effective.  Weekly Romidepsin infusions were added in January.  Last week he had a petscan which showed further shrinkage in the lymph nodes, so progresss is being made with the drug combo.  The goal is to get him to full remission so that he can have an autologous bone marrow transplant.

There have been some side effects.  In January, it was revealed that he had developed heart block, and he had to have a pacemaker implanted.  In February, he started to have issues with the QT Interval on his EKG, which if it continues to get higher, they will have to discontinue the romidepsin.  I don't know what the next step will be in that case.

This month, he is starting to develop high blood pressure.  We don't know why that is happening, and are going to have to have that problem addressed.

Fortunately, there are all sorts of new combos being tried, and combining Romidepsin with Duvelisib, with CHOP, with Pralatrexate and others shows much hope. Dana Farber is one of the best, and it is clear that they know what they are doing, since they stopped CHOEP. That is not an easy regimen in any case. As to the high blood pressure, that is likely a result of the prednisone - which produces all sorts of bad side effects, but makes the environment less hospitable to tumor cells. Over time, prednisone will produce cataracts, thinning of the skin, osteoporosis as well as the hypertension and others. WooHoo!

Back in 2009, Romidepsin placed me in full response and kept me there for 4 1/2 years.

When I began developing cataracts about three years ago, my eye doc, knowing my  medical history, asked if I had received Prednisone, which I did not, since Prednisone is not a regular part of the R-ABVD combination (but I have read patients here mentioning that their doctor added it to R-ABVD for some reason).

He said that he sees a good number of cataract patients who used either Prednisone or some other steroid in the past.  Since probably half of all the patients here have used Prednisone, it is well worth mentionng.

Prednisone

Yes, we have already had bucketloads of Fun Times With Prednisone, so I guess I'm not one bit surprised to hear that it could be the cause of the high blood pressure.  I shall keep out a watch for cataracts as well.  

As an aside, does anyone know what "tracer activity" means in a petscan report?  I can't seem to find any precise definition on the internet.  

Tracer would be the material that they inject for visualization of tumor activity on the PET.  For most of us, the tracer is an analog of the sugar, glucose, called fluorodeoxyglucose or FDG for short.  It is labeled with a very short-lived radioactive molecule so that it can be "seen" by the imager.  Since rapidly dividing cells take up FDG more quickly than normal cells, tumors light up more brightly than surrounding tissue.  The reason that we are told to restrict sugar intake for the 24 - 48 hrs prior to our PET is so that cells are hungrier for sugar and gobble it more quickly.  We are not supposed to indulge in strenous exercise because recovering muscle will also take up the FDG and give a higher background signal.  In general, tissue with tracer activity would imply the presence of tumor, but there can be uptake for other reasons (inflammation), so you need the radiologist's interpretation.
