Oncologic outcomes of postoperative adjuvant versus salvage radiotherapy in prostate cancer.

Introduction: The aim of this study was to compare the long-term oncological results of patients with the diagnosis of prostate cancer who underwent open radical retropubic prostatectomy (RRP) and subsequent adjuvant (ART) or salvage radiotherapy (SRT).

Material And Methods: A total of 145 patients underwent open RRP for prostate cancer and subsequent ART or SRT postoperatively between 2010 and 2019. ART (n = 56) is defined as the group of patients with prostate-specific antigen (PSA) <0.

A retrospective comparison of concurrent bolus 5-fluorouracil or raltitrexed in preoperative chemoradiation for locally advanced rectal cancer.

Background: 5-fluorouracil (FU) is commonly used in preoperative chemoradiation in locally advanced rectal cancer, but not all patients cooperate in taking the 5-day continuous infusion regimen. Raltitrexed (RA), a thymidylate synthase inhibitor, is one of the agents used in place of FU in such cases. We retrospectively compared the toxicity, tumor downstaging, pathologic response and relapse rate with bolus FU or RA during concurrent radiotherapy (RT) to assess the role of RA in place of FU.
