How would you plan adjuvant radiation for an incidental gallbladder carcinoma after cholecystectomy, pT2 with negative margins, now s/p partial hepatectomy and lymphadenectomy with positive nodal disease in a patient who could not tolerate systemic therapy?

Lymphadenectomy demonstrated carcinoma in stations 8, 12A and 12P. What dose/ fractionation would you use, and what volumes would you include?
