Lymphomatoid Granulamatosis

I have recently been diagnosed with grade III lymphomatoid granulamatosis (LYG), it is in both lungs. Pathology report also indicated diffuse large B cell lymphoma. I am a rare case. I am starting 6 rounds of chemo (R-CHOP) tomorrow. I am reaching out as there is not a lot of information online regarding LYG and I see the most recent time this was discussed in this forum was years ago. If anyone has had this in the past or know someone with it and has any suggestions regarding what worked or didn't work as far as treatment please let me know. Thanks in advance.
