Do you routinely add eight extra rituximab doses to six cycles of R-CHOP in elderly patients with DLBCL treated with miniR-CHOP as done in SMARTE-R-CHOP-14 trial ?
I rarely give R-mini-CHOP and even when starting with that regimen I will attempt to escalate as tolerated to standard dosing in elderly patients and as such don’t see much benefit in extra rituximab.
Is concurrent intrathecal therapy necessary with HD-MTX for CNS lymphoma?
Generally, high dose methotrexate has high penetration into the CSF so you do not need to give concurrent intrathecal therapy. The only time you might consider it is if they still have persistent disease in the CSF despite the high dose methotrexate. The approach does not change for primary vs secon...
What is your preferred treatment to ameliorate bone pain from G-CSF?
Loratadine (or cetirizine) used prophylactically before each dose is very effective. There are published cases : https://www.ncbi.nlm.nih.gov/m/pubmed/24664474/ and my experience is this is effective in a vast majority of cases.
What is your approach to the decision to use CPX-351 or standard 7+3 for de novo AML?
CPX-351 is a dual-drug liposomal encapsulation of cytarabine and daunorubicin that delivers a synergistic 5:1 drug ratio into leukemia cells to a greater extent than normal bone marrow cells. It was approved by the FDA in 2017 for the treatment of adults with newly-diagnosed therapy-related acute my...
For a patient with diffuse large B-cell lymphoma of the testicle, do you irradiate the contralateral testicle alone or do you recommend radiation to the lymphatics and remaining testicle?
The most common clinical scenario for primary testicular lymphoma is an older man presenting with a painless testicular mass who undergoes orchiectomy and is found to have DLBCL. Many patients will have stage I disease with post-orchiectomy PET-CT showing no other sites of involvement. Occasionally,...
What is the role for maintenance lenalidomide in elderly patients with DLBCL?
The REMARC study was a phase III trial of maintenance with lenalidomide versus placebo in patients aged 60-80 years old who were in a PR or CR after RCHOP for newly diagnosed DLBCL (Thieblemont et al. JCO 35:2471-2481, 2017.). The results of this large study (650pts) with a median follow up of over ...
Does isolated del(5q) have the same prognostic implications for post-PV secondary myelofibrosis as it does in MDS?
Karyotypic abnormalities are rare in PV and ET. Abnormalities in myelofibrosis (MF) that are associated with an inferior prognosis are: 20q-, 13q-, +9, chromosome 1 translocation/duplication, -Y or sex chromosome abnormality other than –Y. There are few reports of del5q in MPN in general and not eno...
Would you offer scrotal radiation to a patient with a stage IIE bilateral testicular DLBCL treated with a bilateral orchiectomy and chemotherapy?
Bilateral orchiectomy is considered an alternative for those who refuse ISRT to the testicles, so I agree with you that there does not appear to have strong indication for RT in this case. However, there may be a lot of other nuances to this case. I would talk to the surgeon to make sure there was n...
Do you perform biomarker-based screening for AL amyloidosis in patients with newly diagnosed MGUS?
No, unless the patient has signs and symptoms or imaging studies that suggest systemic Amyloidosis.
What is your alternative first line approach to follicular lymphoma that requires treatment if initial treatment with BR leads to significant neutropenia despite G-CSF?
My approach depends on the number of cycles the patient has received and the response to those cycles, along with reason for neutropenia (all treatment based vs disease related). If a patient has significant neutropenia from treatment/therapy, my initial approach would be to add GCSF for the next cy...
