Some info first:
Duration of complaint: 14 days since surgery
Location (Geographic and on body): Poland, GBM
Any existing relevant medical issues (if any): diabetes type 2, atherosclerosis; deep vein thrombosis two years ago
My grandpa (68) has undergone a GBM (or at least what looks like GBM cause we're still waiting for histopathology results of the sample they took during surgery) surgery 14 days ago. The docs told us the results of this biopsy will probably arrive around April 20th so in another 10 days and that the next steps will almost certainly be the usual RT + chemotherapy. The "almost" part is problematic cause healthcare here works in such a way that we need their official statement before progressing with the treatment and for that they need to do a joint consultation, for which they need the histopathology results.
Totalling it all up, it looks like we'll be able to have an appointment with the oncologist (which is a mandatory step before starting RT around here) not sooner than in the last week of April. And the time between this consultation and start of actual RT is usually around _a month_, and I'm talking non-covid times here. All this regretfully makes it look like grandpa will be able to start the actual RT 7-8 weeks after the surgery (~5 weeks after the biopsy report is in).
Is it a reason for concern? Should I try to get a bunch of appointment dates blindly, hoping that we get the histopathology results before they're due so that we can shorten it all by at least a week or is there no reason to panic? Judging by the info online, time is key here and a month after surgery is considered a regular duration before starting RT - but here, we're talking almost twice that worst case scenario and I'm growing a little paranoid cause I wouldn't want grandpa's surgery - which went very good from the surgeon told me - to go in vain just because all the intermittent stuff went so slow that the RT isn't as effective as it could have been.
