The Impact of Blood Transfusion on Recurrence and Mortality Following Colorectal Cancer Resection: A Propensity Score Analysis of 4,030 Patients.

ABSTRACT: Whether blood transfusion exacerbates cancer outcomes after surgery in humans remains inconclusive. We utilized a large cohort to investigate the effect of perioperative blood transfusion on cancer prognosis following colorectal cancer (CRC) resection. Patients with stage I through III CRC undergoing tumour resection at a tertiary medical center between 2005 and 2014 were identified and evaluated through August 2016. Propensity score matching was used to cancel out imbalances in patient characteristics. Postoperative disease-free survival (DFS) and overall survival (OS) were analysed using Cox regression model. A total of 4,030 and 972 patients were analysed before and after propensity score matching. Cox regression analyses demonstrated blood transfusion associated with shorter DFS and OS before and after matching (hazard ratio: 1.41, 95% CI: 1.2-1.66 for DFS; 1.97, 95% CI: 1.6-2.43 for OS). Larger transfusion volume was linked to higher overall mortality (?4 units vs. nil, HR?=?1.58; >4 units vs. nil, HR?=?2.32) but not more cancer recurrence. Preoperative anemia was not associated with decreased survival after adjusting covariates. Perioperative blood transfusion was associated with worse cancer prognosis after curative colorectal resection, independently of anemia status. Strategies aimed at minimizing transfusion requirements should be further developed.

Project description:PurposeThe aim of this study is to investigate the value of total laparoscopic simultaneous colorectal and hepatic resection in patients with synchronous colorectal cancer liver metastases (sCRLMs).MethodssCRLM patients who underwent simultaneous resection from December 2014 to December 2018 in Shanghai Cancer Center, Fudan University were recruited and analyzed retrospectively. The patients were divided into laparoscopic, open, and hybrid surgery groups. The intraoperative information, postoperative short-term outcome, and long-term survival were compared among the three groups. Propensity score matching (PSM) was performed to balance baselines.ResultsA total of 281 patients were recruited. After PSM, 34 patients were selected from both the laparoscopic and the open surgery group. Forty-seven patients were also selected from both the laparoscopic and the hybrid surgery group. The clinicopathologic baselines between the laparoscopic surgery group and the other two groups were well matched. All the operation-related indicators between laparoscopic surgery and hybrid surgery were similar. However, compared with open surgery, laparoscopic surgery showed significantly longer operation time (229.09 ± 10.94 min vs. 192.24 ± 9.49 min, p = 0.013) and less intraoperative blood loss [100.00 (50.00-300.00) ml vs. 200.00 (150.00-400.00) ml, p = 0.021]. For postoperative morbidity, there was no significant difference between the laparoscopic surgery group and the hybrid or the open surgery group (23.40% vs. 31.91% and 17.65% vs. 26.47%, p = 0.356 and p = 0.380). Long-term survival analysis showed that there were no significant differences in all 1-, 3-, and 5-year overall survival, liver recurrence-free survival (RFS), and whole RFS between laparoscopic surgery and hybrid surgery (p = 0.334, p = 0.286, and p = 0.558) or open surgery (p = 0.230, p = 0.348, and p = 0.450).ConclusionsLaparoscopic simultaneous resection for sCRLM shows slight advantages in surgical safety and short-term outcome, and does not compromise long-term survival.

Project description:ImportanceDistant recurrence following preoperative chemoradiotherapy and resection in patients with gastroesophageal adenocarcinoma is common. Adjuvant chemotherapy may improve survival.ObjectiveTo compare adjuvant chemotherapy with postoperative observation following preoperative chemoradiotherapy and resection in patients with gastroesophageal adenocarcinoma.Design, setting, and participantsPropensity score-matched analysis using the National Cancer Database. We included adult patients who received a diagnosis between 2006 and 2013 of clinical stage T1N1-3M0 or T2-4N0-3M0 adenocarcinoma of the distal esophagus or gastric cardia who were treated with preoperative chemoradiotherapy and curative-intent resection. Patients receiving adjuvant chemotherapy were matched by propensity score to patients undergoing postoperative observation.ExposuresAdjuvant chemotherapy and postoperative observation.Main outcomes and measuresOverall survival.ResultsWe identified 10?086 patients (8840 [88%] male; mean [SD] age, 61 [9.5] years), 9272 in the postoperative observation group and 814 in the adjuvant chemotherapy group. Patients receiving adjuvant chemotherapy were younger (18-54 years: 252 [31%] vs 1989 [21%]; P?<?.001) and were more likely to have advanced disease (ypT3/4: 458 [62%] vs 3531 [46%]; P?<?.001; ypN+: 572 [72%] vs 3428 [39%]; P?<?.001), as well as shorter postoperative inpatient stays (>2 weeks: 94 [13%] vs 1589 [20%]; P?<?.001). A total of 732 patients in the adjuvant chemotherapy group were matched by propensity score to 3660 patients in the postoperative observation group. Adjuvant chemotherapy was associated with improved overall survival compared with postoperative observation (median survival: 40 months; 95% CI, 36-46 months vs 34 months; 95% CI, 32-35 months; stratified log-rank P?<?.001; hazard ratio, 0.79; 95% CI, 0.72-0.88). Overall survival at 1, 3, and 5 years was 88%, 47%, and 34% in the observation group, and 94%, 54%, and 38% in the adjuvant chemotherapy group, respectively. Adjuvant chemotherapy was associated with a survival benefit compared with postoperative observation in most patient subgroups.Conclusions and relevanceFor patients with locally advanced gastroesophageal adenocarcinoma treated with preoperative chemoradiotherapy and resection, adjuvant chemotherapy was associated with improved overall survival. Our findings have important implications for the postoperative treatment of this patient group for which few data are available.
