How would you approach a referral for concern for hemochromatosis with ferritin elevation but otherwise normal iron studies?
Interesting questions, but lack of specifics about the degree of elevation and what constitutes normal iron studies makes it difficult to directly answer this question. However, there are well-recognized causes of elevated ferritin due to non-iron overloaded conditions, including increased apoferrit...
How would you approach the management of a patient with elevated iron saturation (60%) and ferritin (500s) with negative genetic testing for hemochromatosis?
I would approach this clinical scenario in the following manner: Always starting with good medical and family history first. Is there any history compatible with secondary hemochromatosis (i.e., history of blood or multiple iron transfusions)? Could the patient be tested for other non-282Y genetic ...
How do you plan to integrate exercise programs after adjuvant chemotherapy in patients with colon cancer, given the results of the CHALLENGE trial?
The CHALLENGE study demonstrated that structured exercise following adjuvant chemotherapy significantly benefits patients with resected high-risk stage II or stage III colon cancer. The study's success hinged on its mandatory behavioral-support sessions. Unlike the control arm, which received only h...
What are some alternatives to dexamethasone for brain edema in patients who are allergic, have an intolerance, or refuse the medication?
Dexamethasone is one of the most frequently prescribed medications in neuro-oncology clinics. Dexamethasone is often favored over other corticosteroids owing to its lower mineralocorticoid effects and high potency as well as essentially 1:1 oral to IV ratio meaning that we use similar IV and oral do...
What is your treatment approach for MAG antibody associated polyneuropathy?
When patients have a classic Distal acquired demyelinating sensory (DADS) Neuropathy phenotype (by clinical +/- EDX criteria), typically an SPEP/IFE is checked first, and if an IgM monoclonal gammopathy is observed, then I typically check MAG antibodies at that point (if clinical and EDX features ar...
When treating a patient with classic early stage diffuse large B-cell lymphoma (Stage I/II), when is it appropriate for patients to receive 3 versus 6 cycles of R-CHOP chemotherapy when the treatment is followed by ISRT?
The SWOG 8736 study included patients with stage I (bulky or non-bulky) and nonbulky stage II aggressive non-Hodgkin lymphomas (mostly DLBCL). Bulky was defined as a mediastinal mass >1/3 maximal chest diameter or any mass > 10 cm. Patients were randomized to 8 cycles of CHOP or 3 cycles of CHOP + R...
How do you approach imetelstat therapy in MDS patients with baseline neutropenia or thrombocytopenia?
Given the fact that the major treatment-emergent adverse events noted on the phase III IMERGE study in the imetelstat-treated arm were neutropenia (68% Grade 3+ tox) and thrombocytopenia (62% Grade 3+ tox), it makes it somewhat difficult to utilize imetelstat (Platzbecker et al., PMID 38048786) in p...

Given the results of LU002 presented at ASCO 2024, are there situations and/or patient subgroups who still derive benefit from local consolidative therapy for oligometastatic NSCLC?
This is a tricky trial to interpret. They allowed a mixture of "stage I" primaries with oligomets and "stage III" locoregional disease with oligomets. The former got SBRT to the primary and the latter got 45 Gy/15 fx to primary and involved LN. There is a huge difference in the "ablativeness" of tho...
In a patient with prior RT to the prostate and SVs and newly diagnosed, locally advanced rectal cancer at 10-15 cm, would you offer preoperative chemoradiation?
"Locally advanced" rectal cancer was traditionally described as T3/4N0M0 or TxN+M0 cancer, but we have advanced much farther on the characterization of this now.We also know that the local control of patients undergoing resection for high rectal cancer (10-15 cm from the anal verge) is much better t...
