Correct answer: D — NACT is preferred when complete cytoreduction at PDS is unlikely (large-volume upper abdominal disease
The EORTC 55971 and CHORUS trials showed that NACT + IDS is non-inferior to PDS for advanced ovarian cancer. However, patients who achieve optimal cytoreduction (no visible residual disease) at PDS have the best outcomes. The decision is guided by: predicted completeness of cytoreduction (assessed by CT/laparoscopy), patient fitness (PS, nutritional status, comorbidities), and surgical expertise. The Fagotti laparoscopic scoring system helps predict completeness of PDS. TRUST/SUNNY trials provide further data.
