How would you manage a patient with essential thrombocythemia and persistent pruritus despite adequate control of CBC with hydroxyurea and aspirin?
First, I'd make sure to exonerate any other causes of itching. Second, would make sure that supportive treatments like good skin care, anti-histamines, anti-depressants have been tried. I'd then consider if this patient truly has ET, as itching is more common in PV. Ruxolitinib is approved for patie...
Which cisplatin regimen is preferred for concurrent chemoradiation for definitive treatment of muscle invasive bladder cancer?
I tend to use 35 - 40 mg/m2 once weekly, ideally on Mondays (I think that SN1806 is using 35 mg/m2 weekly).
Do you consider EBUS TBNA in the diagnostic evaluation of patients with mediastinal lymphadenopathy with concern for lymphoma?
Yes, very commonly. The traditional thought is that histological architecture is needed to diagnose lymphoma. However, with flow-cytometry, we can diagnose all types of NHL. We always try to get a lot of aspirations (more than 7-10 passes) from the lymph nodes or mediastinal masses to prepare a good...
Do you stop PPI when starting patients on immunotherapy?
Proton pump inhibitors (PPI) are commonly used in cancer patients and may affect the gut microbiome by altering gut pH. The gut microbiome plays a critical role in modulating the therapeutic effects of immune checkpoint inhibitors. PPI use in patients treated with immunotherapy has been associated w...
In a patient with stage 1 mixed germ cell tumor who cleared tumor markers post-orchiectomy but with subsequent rise to borderline abnormal within 6 weeks, would you treat with 3 cycles BEP as for S1 disease?
Several points to begin with. My strong preference is to recommend active surveillance for all well documented clinical stage 1 nonseminoma whether or not there is embryonal predominance or lymphovascular invasion present. Second, I do not make treatment decisions based on borderline abnormal normal...
What systemic therapy, if any, would you offer a patient after WBRT for an isolated CNS relapse of initially limited stage SCLC that received chemoRT without PCI?
Since the patient has not progressed outside the CNS, I would hold off on any further therapy till there is evidence of extracranial progression.
How do you manage patients with small, asymptomatic well differentiated PNETs?
Based on available data, nonfunctional low grade PNETs < 1 cm can be monitored with imaging (preferably MRI or triple phase CT). Tumors 1-2 cm are a gray area and consideration of surgery depends on the patient's age, comorbidities, and location of tumor. Tumors > 2 cm should have surgery if possibl...
For a patient with concurrent diagnoses of Hodgkin Lymphoma and Light Chain Myeloma complicated by Myeloma Kidney, how would you approach treatment?
I have seen this once, just once. Two separate but newly diagnosed hematologic malignancies that require treatment simultaneously are rare. More common is a passenger MBL in a myeloma older than 70 y.o., MGUS in the setting of another lymphoid malignancy is not unheard of, and a T-cell gene rearrang...
Would you recommend adjuvant chemotherapy for a patient who achieved a CR after TNT for stage III rectal adenocarcinoma but underwent no initial surgery, and now has a local recurrence >12 months later with plans to undergo low-anterior resection?
I wavered in my response to the poll, which tells me there is no clear "right" answer. The patient has had exposure to FOLFOX already, and assuming margins are negative, it is unclear if there is benefit to more chemo in this resection setting. I think you could apply the data we have for the lack o...
How does urinary obstruction impact your choice of therapy for metastatic or locally advanced prostate cancer?
Bladder outlet obstruction due to locally advanced prostate cancer is typically due to bladder wall and ureteral orifice invasion and T4 disease. These patients can suffer from pain and urinary obstructive symptoms for long periods of time despite the use of ADT, ADT plus AR inhibition, or ADT plus ...
