In that series, postoperative radiation therapy did not improve survival in either resected or palliated patients.
Postoperative radiotherapy does not improve survival. Complete resection of the tumor, especially in early-stage klatzkin, offers hope of long-term survival. With the advances in the sensitivity and specificity of non-invasive imaging tests over recent years, staging laparoscopy is falling into disuse.
