Hey @sweepea32
I’m sorry your sister missed a month of chemo, I know that was a hard choice to make. As Price said, the number one priority with LEMS patients with SCLC is to treat the underlying cancer. Symptoms may worsen if the cancer is not treated.
I personally do not take firdapse but most of the LEMS patients I know do. I was unable to stick to taking it four times a day with my work schedule (I’m an operating room nurse also). There are also a few other treatment options. I receive IVIG (IV Immunoglobulin G) treatments every month that keep my LEMS symptoms at bay for the most part.
Here is a really informative article on some of the other treatment options for LEMS. I also want to share an article on LEMS and cancer with you. If you’re looking for something more detailed about medication/treatment options, the Muscle Dystrophy Association has a ton of LEMS info as well and you can find the article here.
LEMS is normally not usually considered progressive, but patients with cancer seem to have a more progressive course according to the Muscular Dystrophy Association.
I hope this will give you some of the answers you are looking for!
