Is it unusual to have isolated LDH elevation and normal HCG and AFP in non-seminomatous germ cell tumor (embryonal carcinoma)?
It's hard to generalize: the details of the case matter. It is not very unusual to have an isolated LDH elevation. LDH is extremely non-specific. 101 different things can make LDH go up and this limits its usefulness as a tumor marker. Elevation of LDH on day 1 of cycle one of first-line chemotherap...
What is your strategy for treating headaches in patients with history of brain tumor?
Not all headaches in patients with brain tumors arise in the context of elevated ICP, but there are other mechanisms (dural irritation, traction on blood vessels, post-craniotomy pain, for example) by which they can be related. If the headache otherwise seems migrainous, I would treat it as migraine...
Should all pediatric CNS cases be referred to a proton center?
I hope there will be a substantial amount of debate on this question, and so I have invited several pediatric radiation oncologists treating patients at institutions where protons are and are not utilized. The weight of the building data on this topic in the literature is mounting such that more and...
How do you manage incidentally identified pituitary lesions on brain imaging?
Pituitary lesions are among the most common incidentalomas seen on brain MRIs. Various studies cite numbers as high as 10- >30% for pituitary lesions found incidentally on brain imaging, with the higher incidence rates emerging in the era of high-resolution MRIs. In pediatric neurology/neuro-oncolog...
What is your strategy for optimizing hydroxyurea dosage in patients with symptomatic sickle cell disease, particularly for genotypes HbSS and HbS/Beta thal?
I am far, far more worried about underdosing than overdosing. Although HgF is the traditional lab parameter, it may not go up in all patients. I also look for a decrease in reticulocytes, LDH, indirect bili (less hemolysis), less inflammation (WBC and platelets), and a lowering of MCHC (i.e., fewer ...
How would you approach an adolescent patient with stage IIIC serous borderline tumor, s/p fertility sparing surgical staging with unilateral salpingo-oophorectromy, who presents with an enlarging contralateral ovarian mass and additional pelvic disease on imaging?
I would attempt cystectomy and debulking of pelvic disease. If ovarian salvage is not possible, then I would prioritize saving the uterus. If final pathology continued to show borderline tumor, then I would observe. If low-grade serous or high grade serous on final pathology, then I would treat with...
Would you offer adjuvant radiation therapy in a young adult with NF1 who has a craniopharyngioma s/p STR?
In NF1 patients, radiation therapy for craniopharyngioma has been associated with vascular damage and Moya Moya syndrome. On the other hand, subtotally resected craniopharyngiomas have a high chance of recurrence. It has been shown that, dosimetrically, intensity-modulated proton therapy (IMPT) coul...
How do you approach patients with neonatal intrapericardial germ cell tumor, as compared to other patients with mediastinal germ cell tumors?
I need help too!! I have a patient in their teens with recurrent mediastinal GCT. Failed standard therapy radiation HD therapy/stem cell... but never tried immunotherapy, anti-angiogenesis, or TKI. Does anyone have experience with CPI in combination with Lenvatinib??
How do you manage insomnia in cancer patients that is refractory to traditional sleep aides?
Insomnia and other sleep disturbances are very common in individuals diagnosed with cancer, and it is often helpful for patients to hear this. A good history of other contributors to sleep disturbance can be helpful as well. Often, depression, anxiety, and pain, as well as other stimulant medication...
How do you incorporate blinatumomab into therapy for a pediatric or AYA patient with isolated CNS relapse of B-ALL, if at all?
I try to prioritize CAR-T in this setting. Getting there depends on logistics such as financial clearance/collection though. If late relapse or if there is a delay in getting CAR-T, would treat with AALL1331 Arm D (with XRT in mtn), substituting block 3 of blina for block 3 on Arm C (to get more CNS...
