For example, if mass is ulcerated and cannot be excised with polypectomy? Would you ever consider radiation and chemotherapy?

Current NCCN guidelines do not include adjuvant chemotherapy for patients treated in this fashion; however, in the PROSPECT trial itself, an additiona...

Do you find that starting with chemoradiation increases the risk of complete obstruction secondary to transient tumor inflammation, or do you favor st...

Intravesical therapy was delivered two years prior, and last cystoscopy was negative. One-third of the bladder would otherwise be included in the plan...

Especially as the study was done before the adoption of total neoadjuvant therapy

Consider a patient who prioritizes fertility preservation, for whom one of three suspicious nodes approaches the CRM, and is <1 mm from the mesorec...

Would you treat both at the same time? Does one need to be prioritized over the other? Does Xeloda have any efficacy against Merkel cell cancer? How...

With trials like PROSPECT and FOWARC showing no statistically significant improvement in locoregional control and survival outcomes when comparing rad...

Especially consider a situation where surgical excision alone is not appropriate. What if the radiation was LDR or HDR brachytherapy?

How are you approaching patients with rectal cancer who meet PROSPECT criteria but have other higher risk features, such as >4 lymph nodes with sus...

Do you have a preference in ordering MRI, endoscopy, CT scan (chest, abdomen, pelvis), EUS, or other testing before starting any treatment, for re-sta...

Since there is no overlap between chemo regimens for these cancers, how would you sequence treatment? 

What systemic therapy is most appropriate, how would you sequence, and what RT dose fractionation would you use?

Would the location of the tumor (i.e. ultralow), symptoms (bleeding), or patient resistance to surgery play into this decision?

How would you sequence therapy, and what dose and volumes would you use for radiation? Prostate cancer is localized, Gleason 4+3, PSA 65.

Is concurrent chemoradiation reasonable or excessive in a patient with life expectancy <5 yrs? Should the standard be 5 Gy x 5, and will this provi...

Given the published results of the PRODIGE 23 trial where FOLFORINOX was used neoadjuvantly with FOLFOX post-op

Dose-escalation RT trials have had mixed results in the past for advanced rectal cancer, while in the early rectal stage there is a tendency towards a...

How do you weigh definitive chemoRT vs minimally invasive surgical approach with neoadjuvant chemo followed by transanal excision, in light of results...

If records have been destroyed, how do you factor prior pelvic radiation for prostate cancer into your decision?

How does your counseling about side-effects change when offering short vs long course radiation?

If the patient is amenable to adjuvant chemotherapy alone, but is worried about chronic diarrhea/urgency after radiation, how would you counsel them?

I.E., can a patient with a questionable 5 mm node (MRI T2N1) which is negative on pathology after short course radiation be staged T2N0 and receive no...

The patient has disease in the S2/S3 region with an anterior soft tissue mass. The patient previously received 50.4 Gy with treatment for rectal canc...

Are there clinical scenarios in which you have found chemotherapy first has been beneficial?  (i.e., advanced T stage, extra-mesorectal LN, anat...

Do you worry about fluoropyrimidine resistance with concurrent chemoRT? Is there any role for neoadjuvant immunotherapy?

Colleagues in surgery have raised concerns about post radiation effects in the pelvis with the ordering of short course RT->chemo ->surgery.

When using short course RT, the NCCN guidelines currently recommend short course RT followed by chemotherapy, followed by surgery. Many surgeons are h...

Would you consider treating 3-5mm lesions with SBRT or wait until they are a certain size? I am concerned I will not be able to see them adequately on...

Does it ever differ from a standard rectal field? For example, do you always treat the entire rectum, mesorectum, and entire length of internal iliac ...

Is MRI being considered the primary mode of imaging in multidisciplinary tumor boards, especially in light of the results of the MERCURY trial (JCO 20...

Would taking the drug at a specific time point prior to their radiation appointment time to maximize blood levels of the drug be clinically beneficial...
