How would you approach the treatment of a low grade adnexal carcinoma of the scalp in a patient with prior history of WBRT as a child?
Post-op RT and RT alone for the second one, if surgery is not an option. No hypofractionation.
How would you manage the cavity of a resected anaplastic meningioma with pulmonary metastases?
Metastatic meningioma outside the CNS is rare, and its incidence has been estimated to be 0.1% with the lung being the most common site for distant metastases (Surov et al., PMID 23404622). There is no clear standard therapy for the management of metastatic meningioma. Suppose this was an anaplastic...
How do you approach treatment of vulvar cancer with bulky lymph node metastasis?
PET CT. Plan definitive chemo (weekly cisplatinum) with IMRT, with a dose of about equivalent dose of 66 Gy to GTVs. Reassess after 6-8 weeks for excision or bx of any residual disease. Dose-Escalated Intensity Modulated Radiation Therapy in Patients with Locally Advanced Vulvar Cancer- Does It Incr...
What would be the recommended management for patients with rectal adenocarcinoma with rectovaginal fistula at presentation?
Diverting colostomy, preop RT chemo, and surgery.
How would you approach therapy in a young adult with synovial sarcoma of the head and neck who is not amenable to surgery due to location on the face?
I do not think primary synovial sarcoma is curable without surgery. I have never seen a durable response in a tumor treated with radiation alone. Synovial sarcoma responds to ifosfamide based chemotherapy generally, but in my experience, the response rates for primary tumors are lower than response ...
Would the diagnosis of skin-only morphea (localized scleroderma) alter treatment recommendations for localized anal cancer?
There is enough data about the acute and late toxicity from radiation in these patients to be concerned. However, none of it rises to the level of the toxicity of APR. Therefore, my approach would be to involve the patient in the decision, document, and reduce the dose by 10%.
How would you approach palliation of a symptomatic cervical cancer involving the supraclavicular lymph nodes?
Bx- to confirm. I would favor chemo first and if responds to chemo, plan for more definitive dose of RT and if no response, then palliative RT.
What is the role of RT for a patient with double-hit DLBCL and a single site of relapse who can no longer tolerate chemotherapy?
Double-hit DLBCL, now referred to by the WHO as "High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements" is an aggressive non-Hodgkin lymphoma. The MYC rearrangement results in accelerated growth of the lymphoma while a BCL2 rearrangement (more common than BCL6) results in an anti-a...
Would you offer preoperative radiation therapy when treating retroperitoneal sarcomas?
STRASS is a landmark trial and the authors deserve warm congratulations for completing a study of this scale in a rare disease. Its results are very important, but they also must be analyzed thoughtfully and taken in context.Several initial points: The primary endpoint was abdominal recurrence-free ...
In the setting of adjuvant treatment for locally advanced oral cavity cancer, would you offer altered/hypofractionated courses for elderly patients with lower functional status?
At our institution, elderly patients with locally advanced oral cavity cancers who are treated with curative intent oncological resection are typically also treated with curative intent conventionally fractionated adjuvant radiation based on pathological risk factors. For elderly patients with lower...
