How would you manage a female in her 40s with stage III cervical cancer with hydronephrosis and Crohn's disease?

I would treat with definitive chemo RT minimizing bowel exposure as much as I can with IMRT (adaptive if possible so can treat with tighter margin and IGBT) and inform the patient about the risk of complications.

Here is where adaptive RT comes into play to minimize the small bowel dose, in addition to this, I would consider limiting the dose to the lower abdomen if node negative.

Use proton for the external beam component.
