Do you try to incorporate mFOLFIRINOX in total neoadjuvant therapy for rectal cancer?
PRODIGE 23 study is an open-label, randomized phase 3 study (Conroy et al., PMID 33862000). Locally advanced rectal cancer patients (cT3 or cT4 M0) were randomized to either the study arm (mFOLFIRINOX X 3 months, chemoradiation, TME, FOLFOX X 3 months) or the standard arm (chemoradiation followed by...
For multiple myeloma, is 8 Gy in 1 fraction an appropriate palliative dose, although this histology was excluded from trials examining a single fraction?
There was a randomized trial comparing 8 Gy/1 fx vs 30 Gy/10 fx for patients with multiple myeloma. There was no difference in analgesic response or recalcification, however patients with the protracted regimen seemed to have a benefit in terms of QOL. However, the the control arm (30 Gy in 10), th...
Would you recommend stent placement upfront in a patient with cervical esophageal cancer and a TE fistula?
Malignant TE fistula is a complex problem which is often associated with a poor prognosis. Palliation with stenting can be problematic as the stent can erode and make the fistula larger. This is especially problematic with "kissing" stents in both the esophagus and the airway and/or in the setting o...
Would you start anticoagulation in a patient with a history of CVA 1 year ago and high risk APL profile who was never started on anticoagulation, but is now presenting for follow up and without recurrent thrombotic events?
This is a difficult question. The details here are important. Therapeutically, you can go either way in my opinion. Were the positive antiphospholipid antibodies checked again later? Did the patient have an infection when the APS labs were first done? Does the patient have diabetes or other CV risk ...
In what scenario would you prefer weekly vs every 3 week carboplatin/paclitaxel for high grade serous ovarian cancer?
This is a great question without a simple answer. Let’s briefly review the pertinent data, followed by a discussion on how to use the information to consider weekly chemotherapy vs. a standard q 3-week (wk) chemotherapy regimen for primary advanced ovarian cancer.There has been increasing interest i...
What additional testing besides LAC/APLS, factor V Leiden, prothrombin gene mutation, JAK 2 do you draw for unprovoked cerebral venous sinus thrombosis?
Cerebral venous sinus thromboses (CVST) are often put into the category of "thromboses of unusual sites,"--as opposed to the more common lower extremity thromboses or pulmonary emboli.Provoked causes of CVST include pregnancy or exogenous estrogen use, infection of the head/neck or CNS, head trauma,...
How do you approach a patient with recurrent chest wall BRAF(+) mutated melanoma who developed multiple metastatic axillary nodes while on immunotherapy, now post axillary dissection for adjuvant radiation?
This is a patient with recurrent BRAF+ metastatic melanoma who has undergone definitive resection for metastatic lymph nodes. I think it's important to clarify whether this patient progressed after single-agent immune checkpoint therapy (i.e., pembrolizumab or nivolumab) vs dual-immune checkpoint th...
How should a contralateral breast cancer be treated when found during a prophylactic mastectomy?
Whenever a contralateral prophylactic mastectomy is planned, diagnostic imaging of that breast and nodal basin is recommended pre-operatively if not done within the last month or so. Any abnormality should be resolved diagnostically and treated accordingly. Even with this process, incidental cancers...
How do you approach autologous stem cell transplant in T-cell lymphomas/PTCL after induction chemotherapy with achievement of CR1?
Autologous SCT can be considered in PTCL in CR1 especially if the patient is MRD negative by PET and molecular testing (by checking for the persistence of clonal T cells, for example). Schmitz et al., PMID 33512419 If MRD positive CR or PR/SD, would consider allogeneic SCT instead. The main concern ...
