How do you manage a patient with superficial venous thrombosis with close proximity (<3 cm) to deep veins and an inherited thrombophilia ?
I would treat the patient for 3 months with a DOAC and then repeat the scan. If the clot is resolved, I would order a d-dimer and Factor VIII level on anticoagulation. If the tests are negative, I would stop the DOAC and retest at 30, 90, and 180 days. If tests remain negative then stay off anticoag...
How do you approach decision making in terms to adjuvant chemotherapy after CSI in adult medulloblastoma?
Medulloblastoma is a chemotherapy sensitive disease. The NCCN guidelines have options for CSI alone or followed by chemotherapy for standard risk disease (M0, residual disease <1.5cm2, classic or desmoplastic histology) and recommend post-CSI chemotherapy for high risk disease. Unfortunately, 25% of...
How do you manage anaplastic thyroid cancer that is progressing through radiation therapy?
The algorithms for ATC, a rare disease, have gotten relatively complex including the incorporation and timing of XRT. It is unclear from the question what the presentation scenario is, i.e., localized disease or metastatic, and the mutational status, as ideally at a minimum BRAF status is known. Now...
Do you use breast cancer index (BCI) in patients with 1-3 node positive ER+/HER2- IDC?
The only clinical case where I would consider ordering a BCI in a female patient with 1-3 positive lymph nodes would be in a postmenopausal woman who is considering to take adjuvant tamoxifen for 10 years vs 5 years based on the aTTom trial (Bartlett et al., PMID 31504126).I do not order BCI in othe...
Would you give EP chemotherapy to a patient with Stage IIA nonseminoma with negative markers who underwent RPLND and had pN2 disease with predominant teratoma?
For CS IIA disease undergoing open RPLND by an experienced urologist, the long time practice of the groups that I have the fortune to work with closely has been to not given adjuvant therapy since there is a substantial chance of obtaining cure with surgery alone without any chemotherapy. The upstag...
How would you treat a patient with metastatic RCC and significant baseline proteinuria after progression on immunotherapy?
- Tough situation no doubt. I would look for actionable genomic aberrations on NGS though limited in ccRCC. - Consult with a nephrologist and depending on severity of proteinuria, closely monitor proteinuria (urine checks as well as serum protein/albumin levels) with use of VEGFRi (short-acting ones...
What is your typical workup for a patient with a spontaneous renal infarct?
Broadly speaking, in the setting of a renal infarct, consider a thromboembolic event (venous thrombosis with paradoxical embolism or an arterial source) or a local vascular event such as dissection. The latter can be easily missed because the appropriate imaging is generally not performed. Once a va...
How do you approach transplant eligible myeloma patients with a partial or minimal response to treatment with 3-4 cycles of RVD?
This is something that occurs more often than is reported. Put another way, what to do when a patient's response plateaus after achieving a partial response? Evidence suggests that achieving at least a PR during induction is associated with better post-autologous transplant outcomes. What about VGP...
Would you offer gemcitabine-based chemoradiation for a resected node positive cholangiocarcinoma with negative margins that has tolerated adjuvant capecitabine?
For resected cholangiocarcinoma, adjuvant capecitabine is considered standard of care based on the BILCAP trial (Primrose et al., PMID 30922733). This is typically administered up to 6 months following surgery. Based on intention to treat analysis median OS was 51.1 months vs 36.4 months (HR 0.81, P...
What is the optimal prophylaxis regimen to use prior to a selinexor based regimen in the treatment of multiple myeloma for nausea and electrolyte abnormalities?
The official Karyopharm guidelines for nausea are as follows: NK-1R antagonist OR a combination of 5-HT3 antagonist AND olanzapine. So the details are:a) All patients should receive ondansetron 8 mg or equivalent, unless contraindicated, orally 1 hour before each dose of selinexor and q 8 hours for ...
