What would you recommend for a stage I diffuse large B cell lymphoma (IPI 0-1) involving a single lymph node that is completely removed with an excisional biopsy?
Some more info woud be helpful such as age of pt, size and location of node, margins of resection. In general 6 cycles of RCHOP is prefered with RT in almost all instances. 3 cycles is reserved for the most favorable patients. I would add ISRT adhering to recent guidelines from Intl Lymphoma Radiati...
Is it appropriate to re-consider bladder preservation in patients with bladder muscle-invasive cancer (T2) who were initially poor candidates for BP (multifocal disease, etc.) but had complete response after neoadjuvant chemotherapy?
It is perfectly appropriate. There are many ways to achieve a complete response to T2 bladder cancer. It can be reached with radiation, an aggressive local resection, or chemotherapy. The issue is whether or not it is durable. None of these therapies alone have a great track record, although chemoth...
What is your surveillance approach for outpatient monitoring of ICI myocarditis?
At Memorial Sloan Kettering, we do not use surveillance approach for standard ICI therapy. Troponins may be drawn as part of protocols/clinical trials. We do advocate for baseline troponin, especially if high sensitivity troponin is the assay being used. This helps when patients come in with symptom...
For patients with large, partially or nearly obstructing rectal cancers, how do you sequence TNT in order to avoid complete obstruction and surgical diversion?
I personally favor starting with RT/chemo, but starting with chemo can work well. The more important issue is the side questions. First, there is a huge difference between a lesion that is large and one that is nearly completely obstructing. Unfortunately, many endoscopists use the term "obstructing...
Would you consider proton therapy as part of TNT for rectal cancer?
Show me the data. Our results with conventional 3D XRT are excellent with a low rate of chronic toxicities and even lower rates of pelvic recurrences.
Would you offer inguinal nodal RT to a patient with anal SCC (pT1N1a, + inguinal node) following APR in the setting of prior prostate + pelvic nodal radiation?
Inguinal lymph node dissection is not typically part of APR procedures. Even when surgical dissection of the inguinal lymph nodes is performed, the recurrence or failure rates in this region can still be significant, with some studies reporting failure rates of around 10-15% despite extensive surger...
Do you still offer adjuvant chemotherapy and chemoradiation for NSCLC after neoadjuvant chemoimmunotherapy?
In the pre-neoadjuvant era, the options for patients who had R1 (positive margin) or R2 (gross residual disease) were: re-resection followed by adjuvant chemo; sequential adjuvant chemo followed by radiation; or concurrent chemoradiation. There is retrospective data suggesting a survival benefit fro...
How do you treat MAS in patients with systemic JIA or AOSD with HLA-DRB1*15 alleles given risk for DRESS hypersensitivity to IL1 or IL6 inhibitor therapy?
Tough question. HLA-DRB1*15 is pretty common, and it may be a risk allele for lung disease. I, and many others, are not convinced, however, the lung disease represents DRESS, nor that a range of biologics are the etiology of the lung disease. One of my most recent sJIA patients presented with high e...
For a patient with a metastatic solid tumor in remission on a checkpoint inhibitor who also has R/R multiple myeloma, would you feel comfortable with a bispecific T-cell engager antibody?
The short history of checkpoint inhibitors in myeloma has raised some issues with their use. Of course, in this scenario, they are being employed for other cancers, but they may be instructive nonetheless, especially as it pertains to combination strategies. IMiDs and checkpoint inhibitors don't se...
Is post-mastectomy chest wall radiotherapy indicated for DCIS with very close (<1 mm) or positive margins?
As with most clinical situations with limited data, individualized decision-making is key. Based on small series, I do not generally offer RT post mastectomy for DCIS if it is close. If it is clearly involved after reviewing with the pathologist, I would discuss with the surgeon and patient taking i...
