Do you routinely check serum phosphorus levels after IV iron therapy?
I do not routinely monitor serum phosphorus levels after intravenous iron therapy if ferric carboxymaltose (FCM) is not being administered. At our institution, the top two formulary choices for outpatient use for iron repletion are iron sucrose and ferumoxytol, neither of which is associated with a ...
Is your standard of care for newly diagnosed advanced classical Hodgkin now nivolumab-AVD based on SWOG 1826?
I think the new standard of care for newly diagnosed patients with advanced classical Hodgkins Lymphoma is now nivolumab-AVD based on the early data from SWOG 1826. While we often wait for more mature data, the early improvement in PFS and the more favorable toxicity profile of this regimen over BvA...

Should other treatment options be considered for MALT lymphoma if the lacrimal gland will be included in the radiation field in a patient with Sjögren's disease?
The orbit is the second most common site of origin for extranodal marginal zone lymphoma (MZL). Involved orbital structures include the bulbar and/or palpebral conjunctiva, lacrimal gland, and periorbital soft tissues. Patients with Sjögren’s syndrome (SS) are at increased risk for developing extran...
What criteria would you consider to select patients for 20 Gy consolidative RT in DLBCL/HGBL?
The primary endpoint of the study was 5-year local control. The study was powered to estimate this endpoint after the last patient had at least 2 years of potential follow-up (which will be reported at ASTRO). Local failures after 2 years are uncommon. The estimated 5-year freedom from local recurre...
Does the choice of radiation modality (3D, IMRT/VMAT, protons) impact the effectiveness of the reduced dose of 20 Gy in DLBCL?
I don’t think modality (IMRT vs 3D vs protons) has an impact on the effectiveness of the reduced dose of RT.
For biopsy proven extranodal marginal zone lymphoma involving two small bilateral lung nodules, would you consider definitive treatment to both nodules with radiation therapy?
It has been observed that many patients treated with radiation therapy for an extranodal MZL in a paired organ (orbital and parotid, in particular) will develop metachronous disease recurrence in the contralateral organ (Goda et al., PMID 20564130). In fact, it is relatively common for patients with...
For stage III-IV Hodgkin's lymphoma, would you consider consolidative radiation for bulky disease after a complete response was seen using N-AVD per the S1826 trial?
I would offer consolidative radiation only for PET-positive residual disease.
When (if ever) would you offer radiotherapy for renal cell carcinoma following nephrectomy?
There is no indication for any type of radiation after nephrectomy in resected RCC. Often a 'positive' renal vein margin is not a true positive, but rather an artifact of having a renal vein thrombus and this should be discuss with the Urologist and Pathologist and clarified in the report. Having sa...
How would you apply the results of CheckMate 204 in an asymptomatic patient with 10-20 metastatic brain lesions on dual immunotherapy for melanoma?
The results of CheckMate 204 showed that systemic therapy with both nivolumab and ipilimumab has clinically meaningful efficacy in patients with asymptomatic, untreated melanoma metastases to the brain. In this phase 2 study, however, only 22% of the patients had 3 or more lesions. Nevertheless, int...
