ABSTRACT
INTRODUCTION: Despite advancements in colorectal cancer care, one-year post-operative mortality rates remain high for elderly patients who have undergone curative surgery for primary clinical T4 rectal cancer (cT4RC) or locally recurrent rectal cancer (LRRC). This study aimed to identify factors associated with one-year mortality and to evaluate the causes of death. MATERIALS & METHODS: This retrospective cohort study included patients aged ≥70 years who underwent surgery with curative intent for cT4RC or LRRC between January 2013 and December 2020. Clinical and follow-up data were collected and analyzed to determine survival rates and investigate factors associated with mortality within one year after surgery. RESULTS: A total of 183 patients (94 cT4RC, 89 LRRC) were included. One-year mortality rates were 16.0% for cT4RC and 28.1% for LRRC (P = 0.064). In cT4RC patients, factors associated with one-year mortality were preoperative anemia (OR 3.83, P = 0.032), total pelvic exenteration (TPE) (OR 7.18, P = 0.018), multivisceral resections (OR 5.73, P = 0.028), pulmonary complications (OR 13.31, P < 0.001) and Clavien-Dindo grade ≥ III complications (OR 5.19, P = 0.025). In LRRC patients, factors associated with one-year mortality were TPE (OR 27.00, P = 0.008), the need for supported care after discharge (OR 3.93, P = 0.041) and Clavien-Dindo grade ≥ III complications (OR 3.95, P = 0.006). The main causes of death in cT4RC and LRRC patients were failure to recover (cT4RC 26.6%, LRRC 28.0%) and disease recurrence (cT4RC 26.6%, LRRC 60.0%). CONCLUSION: In order to tailor treatment in elderly with cT4RC and LRRC, factors associated with increased one-year mortality (e.g. pre-operative anemia, TPE) should be incorporated in the decision-making process.

INTRODUCTION: The implementation of an Enhanced Recovery After Surgery (ERAS) protocol in patients with locally advanced rectal cancer (LARC) and locally recurrent rectal cancer (LRRC) has been deemed unfeasible until now because of the heterogeneity of this disease and low caseloads. Since evidence and experience with ERAS principles in colorectal cancer care are increasing, a modified ERAS protocol for this specific group has been developed. The aim of this study is to evaluate the implementation of a tailored ERAS protocol for patients with LARC or LRRC, requiring beyond total mesorectal excision (bTME) surgery. METHODS: Patients who underwent a bTME for LARC or LRRC between October 2021 and December 2022 were prospectively studied. All patients were treated in accordance with the ERAS LARRC protocol, which consisted of 39 ERAS care elements specifically developed for patients with LARC and LRRC. One of the most important adaptations of this protocol was the anaesthesia procedure, which involved the use of total intravenous anaesthesia with intravenous (iv) lidocaine, iv methadone, and iv ketamine instead of epidural anaesthesia. The outcomes showed compliance with ERAS care elements, complications, length of stay, and functional recovery. A follow-up was performed at 30 and 90 days post-surgery. RESULTS: Seventy-two patients were selected, all of whom underwent bTME for either LARC (54.2%) or LRRC (45.8%). Total compliance with the adjusted ERAS protocol was 73.6%. Major complications were present in 12 patients (16.7%), and the median length of hospital stay was 9 days (IQR 6.0-14.0). Patients who received multimodal anaesthesia (75.0%) stayed in the hospital for a median of 7.0 days (IQR 6.8-15.5). These patients received fewer opioids on the first three postoperative days than patients who received epidural analgesia (p < 0.001). CONCLUSIONS: The implementation of the ERAS LARRC protocol seemed successful according to its compliance rate of >70%. Its complication rate was substantially reduced in comparison with the literature. Multimodal anaesthesia is feasible in beyond TME surgery with promising effects on recovery after surgery.
