Abstract Background Colorectal cancer is common in elderly patients. Laparoscopy is widely used to approach this kind of disease. This study was to examine short-term outcomes and long-term survival for laparoscopic and open surgery in elderly patients with colorectal cancer. Methods From January 2007 to December 2018, patients with colorectal cancer older than 80 operated at China National Cancer Center were included in the study. Propensity score matching (PSM) was used to minimize the adverse effects. The clinical data between open and laparoscopic surgery was compared, and the effect of factors on overall survival (OS) and disease-free survival (DFS) was analyzed by Cox proportional hazard model. Results Ninety-three pairs were selected after PSM. Patients in laparoscopic group had less intraoperative blood loss, postoperative complications, time to first flatus, time to oral feeding, postoperative hospital stay, and higher retrieved lymph node (P < 0.05). The OS and DFS rates were similar (P > 0.05), besides the CEA level, III/IV stage, and perineural invasion were independent predictors of survival (P < 0.05). Conclusion In elderly patients with colorectal cancer, laparoscopic surgery had better short-term outcomes than open surgery. CEA level, III/IV stage, and perineural invasion were reliable predictors for OS and DFS.

Abstract OBJECTIVES Minimally invasive thoracic surgery has evolved with the introduction of robotic platforms. This study aimed to compare the long-term and short-term outcomes of the robot-assisted thoracic surgery (RATS) and video-assisted thoracic surgery (VATS) for anatomic lung resection. METHODS We searched published studies that investigated RATS and VATS in anatomic lung resection. Long-term outcomes (disease-free survival and overall survival) and short-term outcomes (30-day mortality, postoperative complications, conversion rate to open surgery and lymph node upstaging) were extracted. The features were compared and tested as hazard ratios (HRs) and odds ratios (ORs) at a 95% confidence interval (CI). RESULTS Twenty-five studies with 50 404 patients (7135 for RATS and 43 269 for VATS) were included. The RATS group had a longer disease-free survival than the VATS group (HR: 0.76; 95% CI: 0.59–0.97; P = 0.03), and the overall survival showed a similar trend but was not statistically significant (HR: 0.77; 95% CI: 0.57–1.05; P = 0.10). The RATS group showed a significantly lower 30-day mortality (OR: 0.55; 95% CI: 0.38–0.81; P = 0.002). No significant difference was found in postoperative complications (OR: 1.01; 95% CI: 0.87–1.16; P = 0.94), the conversion rate to open surgery (OR: 0.92; 95% CI: 0.56–1.52; P = 0.75) and lymph node upstaging (OR: 0.89; 95% CI: 0.52–1.54; P = 0.68). CONCLUSIONS RATS has comparable short-term outcomes and potential long-term survival benefits for anatomic lung resection compared with VATS.

3518 Background: Laparoscopic surgery for rectal cancer has been used widely. However, recent two randomized trials raised concerns about short-term oncologic safety of laparoscopic surgery for rectal cancer. The aim of this study was to evaluate the long-term oncologic safety of laparoscopic surgery for rectal cancer based on 7-year data from the Comparison of Open versus laparoscopic surgery for mid or low REctal cancer After Neoadjuvant chemoradiotherapy (COREAN) trial. Methods: COREAN trial was a non-inferiority, randomized controlled trial. Between April, 2006, and Aug, 2009, eligible participants with mid or low rectal cancer treated with preoperative chemoradiotherapy were randomly assigned (1:1) to laparoscopic (n = 170) or open surgery (n = 170). Seven-year outcomes included overall and disease-free survival, and local recurrence. Log-rank test and stratified Cox regression analysis were used for survival analysis. Analysis was by intention to treat. Results: The median follow-up times were 84 months (IQR: 61.5-97.0). No differences were found between laparoscopic and open surgery group in terms of overall and disease-free survival, and local recurrence (7-year overall survival: 83.2% [laparoscopic] vs 77.3% [open], p = 0.48; 7-year disease-free survival: 71.6% [laparoscopic] vs 64.3% [open], p = 0.20; 7-year local recurrence: 3.3% [laparoscopic] vs 7.9% [open], p = 0.08). Stratified Cox regression analysis adjusted for ypT, ypN and tumor regression grade showed no significant difference between groups in terms of overall and disease-free survival, and local recurrence. The hazard ratios for overall survival, disease-free survival and local recurrence (open vs laparoscopic surgery) were 0.96 (95% CI = 0.58-1.57), 1.03 (95% CI = 0.70-1.53), and 2.28 (95% CI = 0.82-7.16), respectively. Conclusions: The 7-year analysis confirm the long-term oncological safety of laparoscopic surgery for rectal cancer treated with preoperative chemoradiotherapy. The use of laparoscopic surgery does not compromise the long-term survival outcomes in rectal cancer. Clinical trial information: NCT00470951.

This study evaluated the correlation between tumor-associated macrophages (TAMs) and long-term oncologic outcomes in colorectal cancer (CRC). We evaluated TAMs based on the expression of CD68, CD11c, and CD163 as optimal markers via immunohistochemistry in 148 patients with CRC who underwent surgical resection between September 1999 and August 2004. A high proportion of CD68-positive macrophages were associated with the occurrence of distant metastasis. A low proportion of CD11c-positive macrophages were associated with unfavorable overall survival (OS) and disease-free survival. CD11c-positive macrophages were found to act as independent prognostic factors for OS. An analysis of our long-term data indicated that TAMs are significantly associated with OS and prognosis in CRC.

Background. Surgery performed by a high-volume surgeon improves short-term outcomes. However, not much is known about long-term effects. Therefore we performed the current study to evaluate the impact of high-volume colorectal surgeons on survival.Methods. We conducted a retrospective analysis of our prospectively collected colorectal cancer database between 2004 and 2011. Patients were divided into two groups: operated on by a high-volume surgeon (>25 cases/year) or by a low-volume surgeon (<25 cases/year). Perioperative data were collected as well as follow-up, recurrence rates, and survival data.Results. 774 patients underwent resection for colorectal malignancies. Thirteen low-volume surgeons operated on 453 patients and 4 high-volume surgeons operated on 321 patients. Groups showed an equal distribution for preoperative characteristics, except a higher ASA-classification in the low-volume group. A high-volume surgeon proved to be an independent prognostic factor for disease-free survival in the multivariate analysisP=0.04. Although overall survival did show a significant difference in the univariate analysisP<0.001it failed to reach statistical significance in the multivariate analysisP=0.09.Conclusions. In our study, a higher number of colorectal cases performed per surgeon were associated with longer disease-free survival. Implementing high-volume surgery results in improved long-term outcome following colorectal cancer.

Abstract Background Laparoscopic surgery for T4 colon cancer may be safe in selected patients. We hypothesized that small tumor size might preoperatively predict a good laparoscopic surgery outcome. Herein, we compared the clinicopathologic and oncologic outcomes of laparoscopic and open surgery in small T4 colon cancer. Methods In a retrospective multicenter study, we reviewed the data of 449 patients, including 117 patients with tumors ≤ 4.0 cm who underwent surgery for T4 colon cancer between January 2014 and December 2017. We compared the clinicopathologic and 3-year oncologic outcomes between the laparoscopic and open groups. Survival curves were estimated using the Kaplan–Meier method and compared using the log-rank test. Univariate and multivariate analyses were performed using the Cox proportional hazards model. A p < 0.05 was considered statistically significant. Results Blood loss, length of hospital stay, and postoperative morbidity were lower in the laparoscopic group than in the open group (median [range], 50 [0–700] vs. 100 [0–4000] mL, p < 0.001; 8 vs. 10 days, p < 0.001; and 18.0 vs. 29.5%, p = 0.005, respectively). There were no intergroup differences in 3-year overall survival or disease-free survival (86.6 vs. 83.2%, p = 0.180, and 71.7 vs. 75.1%, p = 0.720, respectively). Among patients with tumor size ≤ 4.0 cm, blood loss was significantly lower in the laparoscopic group than in the open group (median [range], 50 [0–530] vs. 50 [0–1000] mL, p = 0.003). Despite no statistical difference observed in the 3-year overall survival rate (83.3 vs. 78.7%, p = 0.538), the laparoscopic group had a significantly higher 3-year disease-free survival rate (79.2 vs. 53.2%, p = 0.012). Conclusions Laparoscopic surgery showed similar outcomes to open surgery in T4 colon cancer patients and may have favorable short-term oncologic outcomes in patients with tumors ≤ 4.0 cm.
