Abstract
INTRODUCTION Anastomotic leakage (AL) is one of the most feared postoperative complications in colon cancer surgery due to an association with increased morbidity and mortality, although its impact on long-term survival is not consensual. The aim of this study was to investigate the influence of AL on long-term survival of patients undergoing curative colon cancer resection. METHODS A single-centre retrospective cohort study was designed. Clinical records of all consecutive patients undergoing surgery at our institution between 01/01/2010 and 12/31/2019 were reviewed. Survival analysis was performed by Kaplan-Meier method to estimate overall and conditional survival and Cox regression to search for risk factors impacting survival. RESULTS A total of 2351 patients submitted to colorectal surgery were screened for eligibility, of which 686 with colon cancer were included. AL occurred in 57 patients (8,3%) and was associated with higher postoperative morbidity and mortality, length of stay and early readmissions (P < 0,05). Overall survival was inferior in the leakage group (Hazard Ratio 2,08 [1,02-4,24]). Conditional overall survival at 30, 90 days and 6 months was also inferior in the leakage group (P < 0,05), but not at 1 year. Risk factors independently associated with reduced overall survival included AL occurrence, higher ASA classification and delayed/missed adjuvant chemotherapy. AL did not impact local and distant recurrence (P > 0,05). CONCLUSION AL has a negative impact on survival. Its effect is more pronounced on short-term mortality. AL does not appear to be associated with disease progression.

The effect of reinforcing sutures and trans-anal drainage tube on the outcome of laparoscopic resection for rectal cancer: propensity score‑matched analysis. Langenbecks Arch Surg 2023; 408:289.

Abstract
OBJECTIVES Laparoscopic resection for rectal cancer is currently the predominant treatment modality for rectal tumors, with an ongoing focus on reducing the incidence of postoperative complications. In an effort to decrease the occurrence of anastomotic leakage, two additional steps worth considering are reinforcing the anastomosis with a barbed suture and retaining an anal drain as part of the procedure. The results of the operation were analyzed by comparing them to cases where the anastomosis was performed with a stapler alone. METHODS This study retrospectively analyzed patients who underwent laparoscopic radical rectal cancer surgery between July 2020 and March 2023. The patients were categorized into three cohorts based on the postoperative management following instrumented anastomosis: cohort A, the instrumented anastomosis alone group; cohort B, the reinforced suture group; and cohort C, the reinforced suture and indwelling transanal drainage tube group. Propensity score matching was performed twice in a 1:1 ratio, comparing cohort B to cohort A and cohort C to cohort B. The objective was to compare the benefits and drawbacks among the different groups in terms of operative time, postoperative outcomes and operative costs. RESULTS 529 patients with laparoscopic resection for rectal cancer were eligible for inclusion. the instrumented anastomosis alone group, reinforced suture group and the reinforced suture and indwelling transanal drainage tube group were performed in 205 patients, 198 patients and 126 patients, respectively. Cohort A and Cohort B differed in three variables after PSM: total operative time (p = 0.018), postoperative hospital stay (p < 0.001) and incidence of anastomotic leakage (p = 0.038). Cohort B had a longer total operative time, shorter postoperative hospital stay and a lower incidence of anastomotic leakage. Similarly, cohort C had less postoperative drainage (P = 0.01) and a longer postoperative hospital stay (P = 0.003) when cohort B and cohort C were matched for propensity scores. There was no significant difference in the cost of surgery between the three cohorts. CONCLUSIONS The incorporation of barbed suture reinforcement significantly reduces the occurrence of postoperative anastomotic leakage in rectal cancer surgeries. On the other hand, although trans-anal drainage was used as an additional measure to the reinforcement suture of the anastomosis, the utilization of trans-anal drainage tubes does not demonstrate a significant improvement in surgical outcomes.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies in the world. Despite significant improvements in surgical technique, postoperative complications still occur in a fair percentage of patients undergoing colorectal surgery. The most feared complication is anastomotic leakage. It negatively affects short-term prognosis, with increased post-operative morbidity and mortality, higher hospitalization time and costs. Moreover, it may require further surgery with the creation of a permanent or temporary stoma. While there is no doubt about the negative impact of anastomotic dehiscence on the short-term prognosis of patients operated on for CRC, still under discussion is its impact on the long-term prognosis. Some authors have described an association between leakage and reduced overall survival, disease-free survival, and increased recurrence, while other Authors have found no real impact of dehiscence on long term prognosis. The purpose of this paper is to review all the literature about the impact of anastomotic dehiscence on long-term prognosis after CRC surgery. The main risk factors of leakage and early detection markers are also summarized.

Abstract
BACKGROUND Defunctioning stoma (DS) can decrease the rate of symptomatic anastomotic leakage (AL). Since 2010, we have used tailored, highly selective DS management for low colorectal anastomosis (LCRA). METHODS In total, 433 rectal cancer patients underwent the same standardized procedure. Non-stoma (NS) management was used in patients with no surgical difficulties as well as good colonic preparation and quality of anastomoses. In all other cases, DS was used. C-reactive protein was measured during postoperative follow-up. Imbalance in the initial population was adjusted using propensity-score matching according to sex, age, body mass index, tumor location, and American Society of Anesthesiologists score. Rate of AL within 30 days, 5-year overall survival, local relapse-free survival, and disease-free survival were recorded. RESULTS Anastomosis was mostly ultra-low and was performed equally by laparoscopy or robotic surgery. The overall rate of AL was 13.4%, with no significant differences between groups (DS, 12.2%; NS, 14.6%; p = 0.575). Operative time, blood loss, and hospital stay were significantly lower for NS patients. The rate of secondary stoma was 11.4% overall. Pathological results were similar, with a 98% R0 resection rate. With a median follow-up of 5.5 years for the NS and DS groups, the overall survival was 84.9% and 73.4%, respectively (p = 0.064), disease-free survival was 67.0% and 55.8%, respectively (p = 0.095), and local relapse-free survival was 95.2% and 88.7%, respectively (p = 0.084). The long-term, stoma-free rate was 89.1% overall. CONCLUSIONS Tailoring DS for LCRA seems safe and could provide potential benefits in postoperative morbidity with the same long-term oncological results in NS patients. Prospective, multicentric studies should validate this approach.

Abstract
BACKGROUND Recent studies have clarified that near-infrared observation using indocyanine green has the advantage of evaluating perfusion of the anastomotic site, especially in rectal cancer surgery, resulting in a reduction in anastomotic leak. OBJECTIVE The aim of this study was to evaluate the efficacy of near-infrared observation for reducing the anastomotic leak after stapled side-to-side anastomosis in colon cancer surgery. DESIGN This was a retrospective propensity score case-matched study. SETTINGS The study was conducted at 3 institutions in the Yokohama Clinical Oncology Group. PATIENTS From January 2011 to December 2019, patients who underwent colon cancer surgery with stapled side-to-side anastomosis were included. MAIN OUTCOME MEASURES The main outcome was the percentage of anastomotic leak within 30 days after surgery. RESULTS A total of 1034 patients were collected. There were 532 patients who underwent near-infrared observation and 502 who did not. A total of 370 patients were matched to the near-infrared and non-near-infrared groups. In the near-infrared group, 12 patients (3.2%) were judged to have poor perfusion (4 patients) and no perfusion (8 patients), so the planned transection point was changed. There were no cases of anastomotic leak among these 12 patients. The anastomotic leak rates were 3.5% (13/370) in the non-near-infrared group and 0.8% (3/370) in the near-infrared group. The anastomotic leak and reoperation rates were significantly lower in the near-infrared group than in the non-near-infrared group (OR, 0.224; 95% CI, 0.063-0.794, p = 0.001; OR, 0.348; 95% CI, 0.124-0.977, p = 0.036). LIMITATIONS Although we reduced selection bias by performing propensity score matching, this was a retrospective study and was not randomized. CONCLUSION This large-scale case-matched study showed that assessing perfusion by near-infrared observation significantly reduced the anastomotic leak and reoperation rates after stapled side-to-side anastomosis in colon cancer surgery and may be better suited to colo-colonic anastomosis.

Hubo 532 pacientes que se sometieron a observación con infrarrojo cercano y 502 que no. Un total de 370 pacientes fueron emparejados con los grupos de infrarrojo cercano y no infrarrojo cercano. En el grupo de infrarrojo cercano, se consideró que 12 casos (3,2%) tenían mala perfusión (4 casos) y ninguna perfusión (8 casos), por lo que se cambió el punto de transección planificado. No hubo casos de fuga anastomótica entre estos 12 casos. Las tasas de fuga anastomótica fueron del 3,5% (13/370) en el grupo sin infrarrojo cercano y del 0,8% (3/370) en el grupo con infrarrojo cercano. Las tasas de fuga anastomótica y de reintervención fueron significativamente menores en el grupo con infrarrojo cercano que en el grupo sin infrarrojo cercano (razón de posibilidades 0,224, intervalo de confianza del 95% 0,063-0,794, p = 0,001; razón de posibilidades 0,348, intervalo de confianza del 95% 0,124 -0,977, p = 0,036, respectivamente).LIMITACIONES:Aunque se redujo el sesgo de selección al realizar el emparejamiento por puntaje de propensión, este fue un estudio retrospectivo y no fue aleatorio.CONCLUSIÓN:Este estudio de casos emparejados a gran escala demostró que la evaluación de la perfusión mediante la observación con infrarrojo cercano redujo significativamente la fuga anastomótica y las tasas de reintervención después de la anastomosis latero-lateral con engrapadora en la cirugía de cáncer de colon y puede ser más adecuada para la anastomosis colo-colónica.

Abstract
Background Protective ileostomy is always applied to avoid clinically significant anastomotic leakage and other postoperative complications for patients receiving laparoscopic rectal cancer surgery. However, whether it is necessary to perform the ileostomy is still controversial. This meta-analysis aims to analyze the efficacy of ileostomy on laparoscopic rectal cancer surgery. Methods Cochrane Library, EMBASE, Web of Science, and PubMed were applied for systematic search of all relevant literature, updated to May 07, 2021. Studies compared patients with and without ileostomy for laparoscopic rectal cancer surgery. We applied Review Manager software to perform this meta-analysis. The quality of the non-randomized controlled trials was assessed using the Newcastle-Ottawa scale (NOS), and the randomized studies were assessed using the Jadad scale. Results We collected a total of 1203 references, and seven studies were included using the research methods. The clinically significant anastomotic leakage rate was significantly lower in ileostomy group (27/567, 4.76%) than that in non-ileostomy group (54/525, 10.29%) (RR = 0.47, 95% CI 0.30–0.73, P for overall effect = 0.0009, P for heterogeneity = 0.18, I2 = 32%). However, the postoperative hospital stay, reoperation, wound infection, and operation time showed no significant difference between the ileostomy and non-ileostomy groups. Conclusion The results demonstrated that protective ileostomy could decrease the clinically significant anastomotic leakage rate for patients undergoing laparoscopic rectal cancer surgery. However, ileostomy has no effect on postoperative hospital stay, reoperation, wound infection, and operation time. The efficacy of ileostomy after laparoscopic rectal cancer surgery: a meta-analysis.

Abstract
Importance Pharyngocutaneous fistula (PCF) results in an inflammatory reaction, but its association with the rate of locoregional and distant control, disease-free survival, and overall survival in laryngeal cancer remains uncertain. Objective To determine if pharyngocutaneous fistula after salvage laryngectomy is associated with locoregional and distant control, disease-free survival, and/or overall survival. Design, Setting, and Participants A multicenter collaborative retrospective cohort study conducted at 5 centers in Canada and the US of 550 patients who underwent salvage laryngectomy for recurrent laryngeal cancer from January 1, 2000, to December 31, 2014. The median follow-up time was 5.7 years (range, 0-18 years). Main Outcomes and Measures Outcomes examined included locoregional and distant control, disease-free survival, and overall survival. Fine and Gray competing risk regression and Cox-proportional hazard regression models were used for outcomes. Competing risks and the Kaplan-Meier methods were used to estimate outcomes at 3 years and 5 years. Results In all, 550 patients (mean [SD] age, 64 [10.4] years; men, 465 [85%]) met inclusion criteria. Pharyngocutaneous fistula occurred in 127 patients (23%). The difference in locoregional control between the group of patients with PCF (75%) and the non-PCF (72%) group was 3% (95% CI, -6% to 12%). The difference in overall survival between the group with PCF (44%) and the non-PCF group (52%) was 8% (95% CI, -2% to 20%). The difference in disease-free survival between PCF and non-PCF groups was 6% (95% CI, -4% to 16%). In the multivariable model, patients with PCF were at a 2-fold higher rate of distant metastases (hazard ratio, 2.00; 95% CI, 1.22 to 3.27). Distant control was reduced in those with PCF, a 13% (95% CI, 3% to 21%) difference in 5-year distant control. Conclusions and Relevance This multicenter retrospective cohort study found that development of PCF after salvage laryngectomy is associated with an increased risk for the development of distant metastases.

Lipopolysaccharides increase the risk of colorectal cancer recurrence and metastasis due to the induction of neutrophil extracellular traps after curative resection. J Cancer Res Clin Oncol 2021; 147:2609-2619. [PMID: 34115241 DOI: 10.1007/s00432-021-03682-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 06/02/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Intra-abdominal infection after curative surgery for colorectal cancer is a serious complication associated with an increased risk of recurrence. Lipopolysaccharides (LPS)-an essential component of the cell wall of Gram-negative bacteria-were found to exert a protumorigenic effect by stimulating the inflammatory pathology and formation of neutrophil extracellular traps (NETs). This study was conducted to test whether LPS-induced formation of NETs promotes the development of cancer and metastasis. METHODS The clinical characteristics, incidence of relapse, and serum myeloperoxidase-DNA complexes of 40 patients with infection and 40 patients without infection after curative surgery were analyzed. The effects of LPS on the induction of NETs were evaluated in a mouse model of colorectal cancer and liver metastasis. The toll-like receptor 9 (TLR9)-a DNA receptor-was knocked down to assess its effect on the mitogen-activated protein kinase pathway and activities implicated in the formation of NETs. RESULTS Analysis of the clinical data obtained from these patients showed the significant relation of the formation of NETs and incidence of metastasis and survival rates. Subsequent in vitro experiments revealed an increased level of citrullinated-histone H3 and myeloperoxidase-DNA in LPS-injected mice with colorectal cancer. In the mimic metastatic model, injection of LPS enhanced the metastatic capacity, which was then attenuated by DNase I. This suggested that the formation of NETs was activated by LPS. Injection of TLR9-knockdown HCT116 cells in mice, followed by induction through LPS, mitigated the level of citrullinated-histone H3 and myeloperoxidase-DNA. This finding implied that the formation of NETs was suppressed. CONCLUSION These findings shed light on the mechanism underlying the relationship between the elevated rate of colorectal cancer recurrence in patients who underwent surgery and the incidence of infection. This mechanism involves the protumorigenic activities of LPS-induced formation of NETs. The NETs which could be mediated by the TLR9 and the mitogen-activated protein kinase signaling pathway.

Clinical impact of creatine phosphokinase and c-reactive protein as predictors of postgastrectomy complications in patients with gastric cancer. BMC Cancer 2021; 21:95. [PMID: 33485312 PMCID: PMC7825180 DOI: 10.1186/s12885-021-07801-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Accepted: 01/11/2021] [Indexed: 11/10/2022] Open
Abstract
Background Postoperative complications have been linked to the morbidity and mortality of several cancers. However, predicting whether complications will occur in the early period after surgery or not is challenging. Hence, this study aimed to examine the diagnostic accuracy of serum creatine phosphokinase (CPK) and c-reactive protein (CRP) in predicting the development of postgastrectomy complications. Methods We retrospectively analyzed 188 patients with gastric cancer (GC) who underwent gastrectomy. The diagnostic accuracy of serum CPK and CRP was investigated using the areas under the curves (AUC). The CPK ratio was defined as the CPK on postoperative day (POD) 1 to the CPK on a preoperative day. Results Out of 188 patients, 48 (25.5%) developed postoperative complications. The complications group had a greater operative time (p = 0.037), higher CPK ratio on POD1 (p < 0.0001), and a higher serum CRP level on POD3 (p = 0.001). The AUC for the CPK ratio was 0.772, with an optimal cutoff value of 7.05, whereas that for CRP was 0.659, with an optimal cutoff value of 11.4 mg/L. The CPK ratio on POD1 (p < 0.0001) and the CRP on POD3 (p = 0.007) were independent factors for predicting the development of postgastrectomy complications. The CPK ratio on POD1 and the CRP on POD3 predicted postgastrectomy complications in 41 patients (85.4%). According to combined value of both CPK ratio and CRP level, the positive predictive value and the negative predictive value was 0.70 and 0.829. And sensitivity and specificity were 0.438 and 0.936. Conclusion The CPK ratio on POD1 and the CRP on POD3 after gastrectomy for GC were predictive factors for complication development and may be employed to prevent the development of such complications and improve the prognosis of patients with GC.

Red blood cell transfusions and the survival in patients with cancer undergoing curative surgery: a systematic review and meta-analysis. Surg Today 2021; 51:1535-1557. [PMID: 33389174 DOI: 10.1007/s00595-020-02192-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Accepted: 10/26/2020] [Indexed: 02/08/2023]
Abstract
Allogenic red blood cell transfusions exert a potential detrimental effect on the survival when delivered to cancer patients undergoing surgery with curative intent. We performed a systematic review and meta-analysis to assess the association between perioperative allogenic red blood cell transfusions and risk of death as well as relapse after surgery for localized solid tumors. PubMed, the Cochrane Library, and EMBASE were searched from inception to March 2019 for studies reporting the outcome of patients receiving transfusions during radical surgery for non-metastatic cancer. Risk of death and relapse were pooled to provide an adjusted hazard ratio with a 95% confidence interval [hazard ratio (HR) (95% confidence interval {CI})]. Mortality and relapse associated with perioperative transfusion due to cancer surgery were evaluated among participants (n = 123 studies). Overall, RBC transfusions were associated with an increased risk of death [HR = 1.50 (95% CI 1.42-1.57), p < 0.01] and relapse [HR = 1.36 (95% CI 1.26-1.46), p < 0.01]. The survival was reduced even in cancer at early stages [HR = 1.45 (1.36-1.55), p < 0.01]. In cancer patients undergoing surgery, red blood cell transfusions reduced the survival and increased the risk of relapse. Transfusions based on patients' blood management policy should be performed by applying a more restrictive policy, and the planned preoperative administration of iron, if necessary, should be pursued.

Abstract
BACKGROUND Postoperative complications (POCs) are associated with worse oncologic outcomes in several cancer types. The implications of complications after rectal cancer surgery are not well studied. METHODS The United States Rectal Cancer Consortium (2007-2017) was reviewed for primary rectal adenocarcinoma patients who underwent R0/R1 resection. Ninety-day POCs were categorized as major or minor and were grouped into infectious, cardiopulmonary, thromboembolic, renal, or intestinal dysmotility. Primary outcomes were overall survival (OS) and recurrence-free survival (RFS). RESULTS Among 1136 patients, the POC rate was 46% (n = 527), with 63% classified as minor and 32% classified as major. Of all POCs, infectious complications comprised 20%, cardiopulmonary 3%, thromboembolic 5%, renal 9%, and intestinal dysmotility 19%. Compared with minor or no POCs, major POCs were associated with both worse RFS and worse OS (both p < 0.01). Compared with no POCs, a single POC was associated with worse RFS (p < 0.01), while multiple POCs were associated with worse OS (p = 0.02). Regardless of complication grade, infectious POCs were associated with worse RFS (p < 0.01), while cardiopulmonary and thromboembolic POCs were associated with worse OS (both p < 0.01). Renal POCs were associated with both worse RFS (p < 0.001) and worse OS (p = 0.01). After accounting for pathologic stage, neoadjuvant therapy, and final margin status, Multivariable analysis (MVA) demonstrated worse outcomes with cardiopulmonary, thromboembolic, and renal POCs for OS (cardiopulmonary: hazard ratio [HR] 3.6, p = 0.01; thromboembolic: HR 19.4, p < 0.01; renal: HR 2.4, p = 0.01), and renal and infectious POCs for RFS (infectious: HR 2.1, p < 0.01; renal: HR 3.2, p < 0.01). CONCLUSIONS Major complications after proctectomy for cancer are associated with decreased RFS and OS. Given the association of infectious complications and postoperative renal dysfunction with earlier recurrence of disease, efforts must be directed towards defining best practices and standardizing care.

Abstract
BACKGROUND Anastomotic leakage (AL) is a serious clinical complication after anterior resection for rectal cancer and will lead to an increase in postoperative mortality. However, the effect on long-term oncology outcomes remains controversial. METHODS We searched the PubMed, Embase, and Cochrane library databases for related articles. The included studies assessed local recurrence, distant recurrence, overall survival, cancer-specific survival and disease-free survival. The systematic reviews and meta-analyses was conducted in accordance with the PRISMA guidelines. The combined RRs with 95% CI were then calculated using a fixed effects model or a randomized effect model. RESULTS A total of 18 cohort studies included 34,487 patients who met the inclusion criteria. The meta-analysis demonstrated that AL was associated with increased local recurrence (RR 1.47, 95% CI 1.14-1.90, I = 57.8%). Anastomotic leakage decreased overall survival (RR 0.92, 95% CI 0.88-0.96, I = 58.1%), cancer-specific survival (RR 0.96, 95% CI 0.92-1.00, I = 30.4%), and disease-free survival (RR 0.85, 95% CI 0.77-0.94, I = 80.4%). Distant recurrence may had no significant effects of AL (RR 1.16, 95% CI 0.91-1.46, I = 58.4%). CONCLUSION AL has a negative effect on local recurrence and long-term survival (including overall survival, cancer-specific survival, and disease-free survival) after anterior resection for rectal cancer, but not related to distant recurrence.

Abstract
PURPOSE Evidence on risk factors for postoperative recurrence in patients with colorectal cancer (CRC) confined to pathological stage I is limited. Therefore, this study aimed to identify the risk factors for recurrence in patients with stage I CRC. METHODS Data on clinicopathological factors and blood tests of patients diagnosed with pathological stage I CRC at Hiroshima University Hospital between April 1, 2010, and December 31, 2018, were retrospectively obtained. The statistical significance between the clinical factors and postoperative recurrence was also investigated. RESULTS A total of 244 patients were included. The median observation period was 45 months. There were 17 patients (6.6%) with a postoperative recurrence (8 local and 9 distant recurrences). In the log-lank test, rectal cancer (p = 0.004), pT2 (p = 0.020) and organ/space surgical site infection (SSI) (p = 0.008) were significantly associated with postoperative recurrence. In a multivariate analysis, rectal cancer (hazard ratio [HR] 3.678, 95% confidence interval [CI] 1.184-11.425, p = 0.024) and organ/space SSI (HR 3.137, 95% CI 1.013-9.713, p = 0.047) were independently associated with a higher recurrence rate. Among 18 patients with organ/space SSI, 4 recurrences occurred, all of which were distant metastases. CONCLUSION Organ/space SSI significantly affects the postoperative recurrence in patients with stage I CRC.

Abstract
BACKGROUND Cancer outcomes are complex, involving prevention, early detection and optimal multidisciplinary care. Postoperative infection and surgical site-infection (SSI) are not only uncomfortable for patients and costly, but may also be associated with poor oncological outcomes. A meta-analysis was undertaken to assess the oncological effects of SSI in patients with colorectal cancer. METHODS An ethically approved PROSPERO-registered meta-analysis was conducted following PRISMA guidelines. PubMed and Scopus databases were searched for studies published between 2007 and 2017 reporting the effects of postoperative infective complications on oncological survival in colorectal cancer. Results were separated into those for SSI and those concerning anastomotic leakage. Articles with a Methodological Index for Non-Randomized Studies score of at least 18 were included. Hazard ratios (HRs) with 95 per cent confidence intervals were computed for risk factors using an observed to expected and variance fixed-effect model. RESULTS Of 5027 articles were reviewed, 43 met the inclusion criteria, with a total of 154 981 patients. Infective complications had significant negative effects on overall survival (HR 1·37, 95 per cent c.i. 1·28 to 1·46) and cancer-specific survival (HR 2·58, 2·15 to 3·10). Anastomotic leakage occurred in 7·4 per cent and had a significant negative impact on disease-free survival (HR 1·14, 1·09 to 1·20), overall survival (HR 1·34, 1·28 to 1·39), cancer-specific survival (HR 1·43, 1·31 to 1·55), local recurrence (HR 1·18, 1·06 to 1·32) and overall recurrence (HR 1·46, 1·27 to 1·68). CONCLUSION This meta-analysis identified a significant negative impact of postoperative infective complications on overall and cancer-specific survival in patients undergoing colorectal surgery.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy of indocyanine green (ICG) fluorescence angiography with respect to the anastomotic leakage rate for patients undergoing colorectal operations. METHODS This prospective cohort involved patients who underwent colorectal surgery between August 2018 and September 2019. ICG was injected after colonic transection. Vascular perfusion was observed by ICG fluorescence system before completing anastomosis. Data was compared with those by subjective visual evaluation. The primary outcome was anastomotic leakage rate within 30 days from surgery. RESULTS A total of 131 patients were enrolled, of which ICG was injected in 63 of them. Demographic data were similar between the two groups. There were two (3.23%) and three (4.35%) anastomotic leaks in the ICG and non-ICG group respectively (p = 1.000). Change of resection plane occurred in one patient in the ICG group. There was no ICG related toxicity or adverse events. CONCLUSION ICG fluorescent imaging is a feasible and safe tool to assess colonic vascularisation for patients undergoing colorectal surgery. However, it did not significantly lower the anastomotic leakage rate. ICG should not be routinely used in colorectal surgery before an available large scale randomised controlled trial to prove any clinical benefits.

Abstract
BACKGROUND AND OBJECTIVE Anastomotic leakage is a serious complication after arterial resection of rectal cancer. It has been found that anastomotic leakage is related to the oncological outcome. The purpose of the study is to evaluate the long-term outcome of the rectal tumor after anastomotic leakage. METHODS The effect of anastomotic leakage on the oncological outcome of rectal cancer was studied by electronic literature retrieval. Using the DerSimonian Laird random effect model to calculate the odds ratio and 95% confidence interval. Research heterogeneity was evaluated by Q statistics and I2 , and bias was evaluated by funnel plot and Begg's test. RESULTS A total of 35 studies and 44 698 patients were included in the study. The studies have shown that anastomotic leakage is associated with local recurrence (OR = 1.93; 95% CI, 1.57-2.38; P < .0001), overall survival (OR = 1.64; 95% CI, 1.37-1.95; P < .00001), disease-free survival (OR = 2.07; 95% CI, 1.50-2.87; P < .00001) and cancer-specific survival (OR = 1.32; 95% CI, 1.02-1.70; P = .012), while it was not related to distant recurrence (OR = 1.25; 95% CI, 0.95-1.65; P = .12). CONCLUSIONS The results showed that anastomotic leakage after anterior resection increased the risk of local recurrence, decreased the overall survival, cancer-specific survival and disease-free survival.

In Vivo 2020; 33:2125-2131. [PMID: 31662547 DOI: 10.21873/invivo.11713] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 08/20/2019] [Accepted: 08/28/2019] [Indexed: 01/04/2023]
Abstract
BACKGROUND/AIM The purpose of this retrospective study was to describe the benefits and risks of a diverting stoma (DS) in laparoscopic low anterior resection (LAR) for rectal cancer. MATERIALS AND METHODS A total of 140 and 167 patients without and with DS, respectively, were included in this study in a high-volume cancer center of Japan within an 8-year period. RESULTS Small bowel obstruction occurred more frequently in patients with DS (2.86% vs. 16.17%, p<0.001). The difference in anastomotic leakage rate was not statistically significant (11.43% vs. 10.18%, p=0.72). In multivariate analysis, the operating time was associated with a higher rate of leakage in LAR [odds ratio (OR) 8.772, 95% confidence interval (CI)=1.002-1.012, p=0.027]. CONCLUSION Operating time was associated with a higher rate of leakage in LAR for low rectal cancer. A DS did not reduce anastomotic leakage but increased the risk of postoperative intestinal obstruction in laparoscopic LAR.

Abstract
PURPOSE Several authors have reported an association between anastomotic leak and/or intra-abdominal abscess and oncological survival and recurrence. However, no reports have investigated whether combining anastomotic leak/intra-abdominal abscess and positive drainage culture influences long-term oncological outcomes. Therefore, we defined these complications as postoperative intra-abdominal infections. The present study aimed to evaluate the prognostic impact of postoperative intra-abdominal infections on long-term oncological outcomes after curative stage I-III colorectal cancer surgery. METHODS We performed a retrospective analysis of 755 consecutive patients with stage I-III colorectal cancer undergoing curative surgery between 2010 and 2015 by performing a propensity score-matched analysis to reduce selection bias. RESULTS Of the 755 patients, 62 were matched for postoperative intra-abdominal infections analyses. The median follow-up was 48 months. Compared with the non-infections group, the postoperative intra-abdominal infections group had a significantly shorter local recurrence-free survival (P = 0.01 prior to matching, and P = 0.05 after matching). No significant difference was found between the groups in terms of overall, cancer-specific free, recurrence-free, or distant recurrence-free survival. However, multivariate analyses identified postoperative intra-abdominal infections as an independent prognostic factor for local recurrence-free survival (P = 0.04 prior to matching, and P = 0.03 after matching). CONCLUSIONS In this matched-pair analysis comparing stage I-III colorectal cancer patients with and without postoperative intra-abdominal infections, postoperative intra-abdominal infections were associated with poor local recurrence-free survival, but not overall, cancer-specific free, recurrence-free, or distant recurrence-free survival.

Abstract
Anastomotic leak (AL) remains a potentially life-threatening sequela of colorectal surgery impacting on mortality, short- and long-term morbidity, quality of life, local recurrence (LR) and disease-free survival. Despite technical improvements and the identification of several surgery- and patient-related factors associated to the risk of AL, its incidence has not significantly changed over time. In this context, the clarification of the mechanisms underlying anastomotic healing remains an important unmet need, crucial for improving patients' outcomes. This review concentrates on novel key findings in the etiopathogenesis of AL, how they can contribute in determining LR, and measures which may contribute to reducing its incidence. AL results from a complex, dynamic interplay of several factors and biological processes, including host genetics, gut microbiome, inflammation and the immune system. Many of these factors seem to act in concert to drive both AL and LR, even if the exact mechanisms remain to be elucidated. The next generation sequencing technology, including the microbial metagenomics, could lead to tailored bowel preparations targeting only those pathogens that can cause AL. Significant progress is being made in each of the reviewed areas, moving toward translational and targeted therapeutic strategies to prevent the difficult complication of AL.

Abstract
The breakdown of intestinal anastomosis is a serious postsurgical complication. The worst complication is anastomotic leakage, resulting in contaminated peritoneal cavity, sepsis, multi-organ failure and even death. In problematic locations like the rectum, the leakage rate has not yet fallen below 10 %. Such a life-threatening condition is the result of impaired healing in the anastomotic wound. It is still vital to find innovative strategies and techniques in order to support regeneration of the anastomotic wound. This paper reviews the surgical techniques and biomaterials used, tested or published. Electrospun nanofibers are introduced as a novel and potential material in gastrointestinal surgery. Nanofibers possess several, unique, physical and chemical properties, that may effectively stimulate cell proliferation and collagen production; a key requirement for the healed intestinal wound.

Abstract
BACKGROUND/OBJECTIVE Anastomotic leakage (AL) is one of the most severe complications following colorectal cancer surgery and is associated with increased short and long term mortality. The literature is conflicting regarding increased risk of recurrence after AL. The aim of this study was to systematically review the impact of anastomotic leakage on the risk of local or distant recurrence and overall survival, cancer specific survival, and disease-free survival. METHODS A systematic review and meta-analysis was conducted in accordance with the PRISMA guidelines. A systematic search in PubMed, EMBASE, CINHAL, and The Cochrane Library was performed and meta-analyses were performed on all outcomes including analysis based on time-to-event data. RESULTS A total of eighteen cohort studies, including 69,047 patients whereof 2,555 patients had anastomotic leakage, were included. Meta-analysis demonstrated no significant effects of anastomotic leakage on local recurrence (RR 1.16, 95% CI 0.84-1.59) or distant recurrence (RR 1.44, 95% CI 0.52-3.96). Anastomotic leakage decreased overall survival (RR 0.85, 95% CI 0.77-0.94), disease free survival (RR 0.80, 95% CI 0.72-0.89), and cancer specific survival (RR 0.90, 95% CI 0.83-0.97). A time-to-event analysis was conducted on available data and the results were congruent with the frequency analyses. CONCLUSION Anastomotic leakage following colonic resections is significantly associated with impaired overall survival, disease free survival and cancer specific survival. The study did not show any statistically significant association between anastomotic leakage and recurrence.

Abstract
AIM Surgery for colorectal cancer is associated with a high incidence of postoperative complications. The aim of this study was to analyse whether postoperative complications following radical resection for colorectal cancer are associated with increased recurrence rate and impaired survival. METHOD Patients operated for colon cancer between 2007 and 2009 with curative intent were identified through the Swedish Colorectal Cancer Registry. The cohort was divided into three subgroups: patients who developed severe postoperative complications, patients who developed non-severe complications and patients who did not develop any complication (controls). RESULTS Of 6779 patients included in the study, 640 (9%) developed severe complications, 994 (15%) non-severe complications and 5145 (76%) had no complications. The 5-year overall survival rate was 60.3% in the severe complication group, 64.2% in the non-severe complication group and 72.8% in the control group (P < 0.01). The 3-year disease-free survival rate was 66.8%, 70.9% and 77.8% respectively (P < 0.01). The recurrence rate did not differ between the three groups. In multivariate analysis, both severe and non-severe complications were found to be risk factors for decreased overall survival at 5 years [hazard ratio (HR) 1.38, 95% CI 1.47-1.92, and HR 1.18, 95% CI 1.27-1.60 respectively; P < 0.05) as well as for decreased 3-year disease-free survival (HR 1.37, 95% CI 1.14-1.65, and HR 1.26, 95% CI 1.08-1.48 respectively; P < 0.05). CONCLUSION Complications after colonic resection for cancer are associated with impaired 5-year overall survival and 3-year disease-free survival and exhibit more severe postoperative complications, mainly via mechanisms other than cancer recurrence.

Indocyanine green fluorescence imaging to reduce the risk of anastomotic leakage in laparoscopic low anterior resection for rectal cancer: a propensity score-matched cohort study. Surg Endosc 2019; 34:202-208.

Abstract
BACKGROUND Recent studies have shown the potential benefit of indocyanine green fluorescence imaging (ICG-FI) in lowering the anastomotic leakage (AL) rates by changing the surgical plan. The aim of this study was to evaluate the effect of ICG-FI on the AL rates in laparoscopic low anterior resection (LAR) for rectal cancer. METHODS From September 2014 to December 2017, data from patients who underwent laparoscopic LAR for rectal cancer were collected and analyzed. The primary endpoint was the AL rate within 30 days after surgery. The incidence of AL in patients who underwent ICG (ICG-FI group) was compared with that in patients who did not undergo ICG (non-ICG-FI group) using propensity score matching. RESULTS Data from 550 patients were collected from 3 institutions. A total of 211 patients were matched in both groups by the propensity score. ICG-FI shifted the point of the proximal colon transection line toward the oral side in 12 patients (5.7%). The AL rates of Clavien-Dindo (CD) grade ≥ II and ≥ III were 10.4% (22/211) and 9.5% (20/211) in the non-ICG-FI group and 4.7% (10/211) and 2.8% (6/211) in the ICG-FI group, respectively. ICG-FI significantly reduced the AL rate of CD grade ≥ II and ≥ III (odds ratio (OR) 0.427; 95% confidence interval (CI) 0.197-0.926; p = 0.042 and OR 0.280; CI 0.110-0.711; p = 0.007, respectively). The rate of reoperation was significantly lower (OR 0.192; CI 0.042-0.889; p = 0.036) and the postoperative hospital stay significantly shorter (mean difference 2.62 days; CI 0.96-4.28; p = 0.002) in the ICG-FI group than in the non-ICG-FI group. CONCLUSIONS ICG-FI was associated with significantly lower odds of AL in laparoscopic LAR for rectal cancer. CLINICAL TRIAL The study was registered with the Japanese Clinical Trials Registry as UMIN000032654.

Abstract
The PRL-3 gene is involved in the liver metastasis of colorectal cancer (CRC) and oncogene addiction to anticancer therapy. In the present study genomic gains in PRL-3 and its pathway genes, c-myc and EGFR, were investigated in order to determine their clinical relevance during metastatic formation in primary CRC and corresponding liver metastases. The genomic gain statuses of PRL-3, EGFR, and c-myc were investigated using quantitative polymerase chain reaction (qPCR) analysis in 35 samples of CRC and corresponding liver metastases. In the primary CRC specimens, genomic gains in PRL-3, c-myc, and EGFR were observed in 4, 4, and 13 cases, respectively. A genomic gain in one gene was observed in 18 cases, and these genomic gains were mutually exclusive. In the liver metastasis specimens, genomic gains were observed in 14, 8, and 13 cases, respectively. The copy numbers of PRL-3 and c-myc were significantly higher in the liver metastases than in the primary CRC specimens (P=0.03, P=0.009, respectively). A genomic gain in PRL-3 was the most frequent gain in the liver metastases (P=0.004) and was partially redundant with a c-myc genomic gain. EGFR genomic gains were consistent between the primary CRC and the liver metastases (P=0.0000008). In addition, a genomic gain in any of the 3 genes was observed in 23 cases (66%). Among the clinicopathological factors that were assessed, an EGFR genomic gain was significantly associated with tumour size in the primary CRC and the liver metastases (P=0.04). A c-myc genomic gain was also significantly associated with the v factor of the primary tumours in the liver metastases (P<0.01). In conclusion, the genomic copy numbers of PRL-3, c-myc and EGFR were frequently characterised by aberrations in genomic gain in liver metastases from CRC; thus, these gene statuses exhibit potential for the identification of patients who are likely to respond positively to anticancer therapies.

Abstract
BACKGROUND Whether high body mass index (BMI) was associated with increased postoperative complications and unfavorable prognosis of gastric cancer (GC) patients remain controversial. In the present study, we performed a systematic review and meta-analysis to evaluate the impact of high BMI on surgical outcome, postoperative complications and long-term survival of GC patients. METHODS The related studies were identified by searching PubMed and Embase databases. According to the BMI, all GC patients were classified into BMI ≥25 kg/m2 group and BMI <25 kg/m2 group. The relevant data was extracted and pooled effect size was assessed using a fixed effect model or random effect model. RESULTS A total of 36 relevant studies involving 30,642 GC patients were included in this meta-analysis. The results indicated that high BMI patients had longer operation time, fewer number of retrieved lymph nodes and larger amount of intraoperative blood loss than other patients, regardless of open gastrectomy or laparoscopic gastrectomy. In addition, the risk of postoperative complications was significantly higher in the patients with BMI ≥25 kg/m2 than in those with BMI <25 kg/m2, especially for infectious complications. However, high BMI had no negative impact on postoperative mortality and long-term survival of GC patients. CONCLUSION Despite the increased surgical difficulty and postoperative complications, high BMI was not associated with the prognosis of GC patients. To reduce the risk of postoperative complications, more meticulous operation technique and improved perioperative management should be necessary for high BMI patients.

Spillage of bacterial products during colon surgery increases the risk of liver metastases development in a rat colon carcinoma model. Oncoimmunology 2018; 7:e1461302. [PMID: 30228930 PMCID: PMC6140552 DOI: 10.1080/2162402x.2018.1461302] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Revised: 03/28/2018] [Accepted: 03/30/2018] [Indexed: 01/03/2023] Open
Abstract
Surgical resection of the primary tumor provides the best chance of cure for patients with colorectal carcinoma (CRC). However, bacterial translocation during intestinal surgery has been correlated with poor long-term oncological outcome. Therefore, we investigated the influence of bacterial contamination during colon surgery on CRC liver metastases development. Blood and liver samples of patients undergoing resection of primary CRC or liver metastases were collected. Cell numbers, activation markers and inflammatory mediators were determined. Tumor cell adhesion and outgrowth after sham- or colectomy operations were determined in a rat model, in which tumor cells had been injected into the portal vein. White blood cells and granulocytes were increased in per- and post-operative patient blood samples. IL-6 was also increased post-operatively compared to the preoperative level. Expression of NOX-2, NOX-4 and polymorphonuclear cells (PMNs) numbers were elevated in post-operative human liver samples. In vitro stimulation of macrophages with plasma of rats after colectomy resulted in production of reactive oxygen species (ROS). Colectomy in rats increased D-lactate levels in plasma, supporting bacterial translocation. Decreased expression of tight junction molecules and increased tumor cell adhesion and outgrowth was observed. Treatment with a selective decontamination of the digestive tract (SDD) cocktail decreased tumor cell adherence after colectomy. In conclusion, postoperative bacterial translocation may activate liver macrophages and PMNs, resulting in ROS production. As we previously showed that ROS release led to liver vasculature damage, circulating tumor cells may adhere to exposed extracellular matrix and grow out into liver metastases. This knowledge is pivotal for development of therapeutic strategies to prevent surgery-induced liver metastases development.

Defunctioning ileostomy reduces leakage rate in rectal cancer surgery - systematic review and meta-analysis. Oncotarget 2018; 9:20816-20825. [PMID: 29755692 PMCID: PMC5945534 DOI: 10.18632/oncotarget.25015] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2017] [Accepted: 03/08/2018] [Indexed: 12/11/2022] Open
Abstract
Objectives The role of a defunctioning ileostomy in every anterior rectal resection with total mesorectal excision (TME) is still controversial. In this study, we aimed to review the current literature to determine the impact of ileostomy creation on postoperative outcomes in patients undergoing anterior rectal resection with TME. Methods MEDLINE, Embase and Cochrane Library were searched for eligible studies. We analyzed data up to October 2017. Eligible studies had to compare patients with vs. without a defunctioning ileostomy in rectal cancer surgery and comprise data on anastomotic leakage in both groups. The primary outcome was anastomotic leakage. Secondary outcomes included the complication rate, mortality, reoperation rate, length of hospital stay and 30-day readmission. Results Initial search yielded 1,966 articles. Thorough evaluation resulted in 13 eligible articles which were analyzed. Leakage rate (RR = 0.43, 95% CI 0.28-0.67) and the number of reoperations (RR = 0.62, 95% CI 0.40-0.94) were significantly lower in the defunctioning stoma group. Morbidity was significantly higher in the stoma group (RR = 1.32, 95% CI 1.05–1.65). Analysis of mortality, length of hospital stay and readmission rate did not show any significant differences. Conclusion A defunctioning ileostomy may decrease the anastomotic leakage rate, additionally significantly reducing the risk of reoperations but it may also increase the overall complication rate. The presence of the protective stoma has no effect on mortality, length of hospital stay and readmission rate.

Postoperative intra-abdominal infection is an independent prognostic factor of disease-free survival and disease-specific survival in patients with stage II colon cancer. Clin Transl Oncol 2018; 20:1321-1328. [PMID: 29623587 DOI: 10.1007/s12094-018-1866-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2017] [Accepted: 03/22/2018] [Indexed: 02/08/2023]
Abstract
BACKGROUND Recurrence occurs in up to 20% of patients with stage II colon cancer operated on for cure. Although postoperative intra-abdominal infection has been linked with an increased risk of recurrence, the association is controversial. The aim was to investigate the impact of postoperative intra-abdominal infection on disease-free survival and disease-specific survival in patients with stage II colon cancer. METHODS Patients undergoing elective surgery for colon cancer stage II, between 2003 and 2014, were included. Patients with anastomotic leak or intra-abdominal abscess were included in the infection group. We used the Kaplan-Meier method to represent the distribution of survival and the Cox proportional hazards model to estimate the contribution of relevant clinicopathological factors with prognosis. RESULTS Postoperative intra-abdominal infection was diagnosed in 37 of 363 (10.2%) patients. Perioperative blood transfusion was more frequent in patients with infection (p = 0.008). Overall 5-year disease-free survival rate was 85.1%. Disease-free survival at 5 years was lower in patients with postoperative intra-abdominal infection (52.8 vs 88.7%; p < 0.001), perineural invasion (p = 0.001), lymphovascular invasion (p = 0.001), pT4 (p = 0.013), and in patients with adjuvant chemotherapy (p = 0.013). Multivariate analysis showed that postoperative intra-abdominal infection (HR 4.275; p < 0.001), perineural invasion (HR 2.230; p = 0.007), and lymphovascular invasion (HR 2.052; p = 0.016) were all significant independent predictors of reduced disease-free survival. Regarding specific survival, independent significant prognostic factors were the number of lymph nodes, lymphovascular invasion, and postoperative intra-abdominal infection. CONCLUSION In this series of patients with stage II colon cancer, postoperative intra-abdominal infection has an independent negative impact on disease-free survival and disease-specific survival.

Abstract
Colorectal cancer (CRC) is the key leading cause of high morbidity and mortality worldwide. Surgical excision is the most effective treatment for CRC. However, stress caused by surgery response can destroy the body's immunity and increase the likelihood of cancer dissemination and metastasis. Anesthesia is an effective way to control the stress response, and recent basic and clinical research has shown that anesthesia and related drugs can directly or indirectly affect the immune system of colorectal cancer patients during the perioperative period. Thus, these drugs may affect the prognosis of CRC surgery patients. This review is intended to summarize currently available data regarding the effects of anesthetics and related drugs on perioperative immune function and postoperative recurrence and metastasis in CRC patients. Determining the most suitable anesthesia for patients with CRC is of utmost importance.

Abstract
Peritoneal infection after colorectal cancer surgery is associated with a higher rate of tumor relapse. We have recently proposed that soluble inflammatory factors released in response to a postoperative infection enhance tumor progression features in residual tumor cells. In an effort to set up models to study the mechanisms of residual tumor cell activation during surgery-associated inflammation, we have analyzed the phenotypic response of colon cancer cell lines to the paracrine effects of THP-1 and U937 differentiated human macrophages, which release an inflammatory medium characteristic of an innate immune response. The exposure of the colon cancer cell lines HT-29 and SW620 to conditioned media isolated from differentiated THP-1 and U937 macrophages induced a mesenchymal-like phenotypic shift, involving the activation of in vitro invasiveness. The inflammatory media activated the β-catenin/TCF4 transcriptional pathway and induced the expression of several mesenchymal (e.g., FN1 and VIM) and TCF4 target genes (e.g., MMP7, PTGS2, MET, and CCD1). Similarly, differential expression of some transcription factors involved in epithelial-to-mesenchymal transitions (i.e. ZEB1, SNAI1, and SNAI2) was variably observed in the colon cancer cell lines when exposed to the inflammatory media. THP-1 and U937 macrophages, which displayed characteristics of M1 differentiation, overexpressed some cytokines previously shown to be induced in colorectal cancer patients with increased rates of tumor recurrence associated with postoperative peritoneal infections, thus suggesting their pro-tumoral character. Therefore, the environment created by inflammatory M1 macrophages enhances features of epithelial-to-mesenchymal transition, and may be useful as a model to characterize pro-inflammatory cytokines as putative biomarkers of tumor recurrence risk.

Abstract
Background Few studies have evaluated the long-term impact of postoperative infectious complications in patients with non-small cell lung cancer (NSCLC). We aimed to determine the impact of infectious complications on long-term outcomes after surgical resection for NSCLC. Methods We performed a retrospective study of 1,380 eligible patients who underwent pulmonary resection for NSCLC from 2003 to 2012. Complications were divided into infectious complications and non-infectious complications. Kaplan-Meier survival analysis was used to compare unadjusted 5-year cancer-specific survival (CSS) rates and recurrence-free survival (RFS) rates. Cox regression was used to determine the impact of infectious complications on 5-year CSS and RFS. Results The rate of total complications and infectious complications was 24.3% and 4.3%, respectively. In the node-negative subgroup, the 5-year CSS and RFS rates were 75.9% and 57.1% in patients who had infectious complications, compared to 87.9% and 78.4% in patients who had no complications. Infectious complications were a negative prognostic factor for 5-year RFS (hazard ratio, 1.92; 95% confidence interval, 1.00–3.69; p=0.049). In the node-positive subgroup, the 5-year CSS rate and RFS were 44.6% and 48.4% in patients who had infectious complications, compared to 70.5% and 48.4% for patients who had no complications. Conclusion Postoperative infectious complications had a negative impact on CSS and RFS in node-negative NSCLC. Our findings may help improve risk assessment for tumor recurrence after pulmonary resection for node-negative NSCLC.

Abstract
BACKGROUND Indocyanine green (ICG) fluorescence imaging has been proven to be an effective tool to assess anastomotic perfusion. The aim of this systematic review and meta-analysis was to evaluate its efficacy in reducing the anastomotic leakage (AL) rate after colorectal surgery. METHODS PubMed, Scopus, WOS, Google Scholar and Cochrane Library were searched up to January 2017 for studies comparing fluorescence imaging with standard care. ClinicalTrials.gov register was searched for ongoing trials. The primary outcome measure was AL rate with at least 1 month of follow-up. ROBINS-I tool was used for quality assessment. A meta-analysis with random-effects model was performed to calculate odds ratios (ORs) from the original data. RESULTS One thousand three hundred and two patients from 5 non-randomized studies were included. Fluorescence imaging significantly reduced the AL rate in patients undergoing surgery for colorectal cancer (OR 0.34; CI 0.16-0.74; p = 0.006). Low AL rates were shown in rectal cancer surgery (ICG 1.1% vs non-ICG 6.1%; p = 0.02). There was no significant decrease in the AL rate when colorectal procedures for benign and malignant disease were combined. To date, there are no published randomized control trials (RCTs) on this subject, though 3 ongoing RCTs were identified. CONCLUSIONS ICG fluorescence imaging seems to reduce AL rates following colorectal surgery for cancer. However, the inherent bias of the non-randomized studies included, and their differences in AL definition and diagnosis could have influenced results. Large well-designed RCTs are needed to provide evidence for its routine use in colorectal surgery.

Abstract
High-risk patient selection is required in N0 colon cancer. Although a number of studies have suggested high-risk clinicopathological predictors, most of these are based on analyses in heterogeous patients in terms of surgical procedures. Laparoscopic surgery for colon cancer is becoming a standard procedure worldwide because of its less invasiveness. Accordingly, we aimed to identify bona fide high-risk factors of recurrence in homogeneous N0 patients who underwent laparoscopic surgery. Two hundred and twenty-five patients who underwent laparoscopic curative resection for N0 colon cancer were analyzed. Clinicopathological parameters were tested for their relation to survival. The 5-year recurrence-free survival rate (RFS) was 96.1 per cent. Lymphatic involvement (P < 0.001), vascular involvement (P = 0.007), and size of tumor (P = 0.023) were significantly associated with worse prognosis in the univariate analyses. Lymphatic involvement was the independent prognostic factor associated with RFS in the multivariate analysis (P = 0.013). Importantly, lymphatic involvement predicts detrimental prognosis only when vascular involvement is present. The RFS of the patients with both lymphatic and vascular involvement was 88.9 per cent, whereas it was 100 per cent in the counterpart. Differentiation, vascular involvement preoperative carcinoembryonic antigen, and CA 19-9 levels were significantly associated with lymphatic involvement in a multivariate logistic regression analyses. The present study concludes that lymphatic involvement in the presence of vascular involvement may be a high risk for systemic recurrence in the laparoscopically resected N0 colon cancer.

Abstract
BACKGROUND In rectal cancer, the significance of abdominopelvic sepsis (APS) on metastatic tumor growth remains uncertain. We aimed to analyze the effect of abdominopelvic sepsis on long-term survival in patients undergoing restorative rectal cancer surgery. METHODS Data were used from the Belgian PROCARE rectal cancer registry. The effect of abdominopelvic infection on survival was assessed in uni- and multivariable Cox regression models. The effect of clinical and pathological covariates was controlled by propensity score-based matching of cases with controls. The effect of abdominopelvic sepsis on the rate of local and metastatic recurrence was evaluated using crosstabulation and the Pearson χ2 test. RESULTS In univariable analysis, the presence of APS was associated with significantly worse overall survival (HR 1.3, P = 0.025). After propensity score matching including age, BMI, tumor level, pTstage, pN stage, CRM, tumor grade, number of lymph nodes, and presence of lymphovascular invasion, the association of APS with OS was no longer significant (HR 1.26, 95%CI 0.92-1.74, P = 0.15). No differences were observed in the risk of local or metastatic recurrence (3.6% vs 2.9% and 13% vs 16.5%). CONCLUSIONS In this analysis APS after rectal cancer resection was not significantly associated with OS, metastatic, or local recurrence.

Abstract
AIM Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leucocytes (PBL) after surgery for colorectal cancer. METHOD Prospective matched cohort study. Patients undergoing surgery for colorectal cancer were included. Patients who had anastomotic leak or intra-abdominal abscess were included in the infection group (n = 23) and matched with patients without complications for the control group (n = 23). PBL were isolated from postoperative blood samples. Total RNA was extracted and hybridized to the Affymetrix Human Gene 1.0 ST microarray. RESULTS Patients in the infection group displayed 162 upregulated genes and 146 downregulated genes with respect to the control group. Upregulated genes included examples coding for secreted cytokines involved in tumour growth and invasion (S100P, HGF, MMP8, MMP9, PDGFC, IL1R2). Infection also upregulated some proangiogenic genes (CEP55, TRPS1) and downregulated some inhibitors of angiogenesis (MME, ALOX15, CXCL10). Finally, some inhibitors (HP, ORM1, OLFM4, IRAK3) and activators (GNLY, PRF1, FGFBP2) of antitumour immunity were upregulated and downregulated, respectively, suggesting that the inflammatory environment caused by a postoperative infection favours immune evasion mechanisms of the tumour. CONCLUSION Analysis of PBL shows differential expression of certain tumour progression-related genes in colorectal cancer patients who have a postoperative intra-abdominal infection, which in turn may promote the growth of residual cancer cells to become recurrent tumours.

Peritoneal expression of Matrilysin helps identify early post-operative recurrence of colorectal cancer. Oncotarget 2016; 6:13402-15. [PMID: 25596746 PMCID: PMC4537023 DOI: 10.18632/oncotarget.2830] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2014] [Accepted: 11/27/2014] [Indexed: 12/20/2022] Open
Abstract
Recurrence of colorectal cancer (CRC) following a potentially curative resection is a challenging clinical problem. Matrix metalloproteinase-7 (MMP-7) is over-expressed by CRC cells and supposed to play a major role in CRC cell diffusion and metastasis. MMP-7 RNA expression was assessed by real-time PCR using specific primers in peritoneal washing fluid obtained during surgical procedure. After surgery, patients underwent a regular follow up for assessing recurrence. transcripts for MMP-7 were detected in 31/57 samples (54%). Patients were followed-up (range 20-48 months) for recurrence prevention. Recurrence was diagnosed in 6 out of 55 patients (11%) and two patients eventually died because of this. Notably, all the six patients who had relapsed were positive for MMP-7. Sensitivity and specificity of the test were 100% and 49% respectively. Data from patients have also been corroborated by computational approaches. Public available coloncarcinoma datasets have been employed to confirm MMP7 clinical impact on the disease. Interestingly, MMP-7 expression appeared correlated to Tgfb-1, and correlation of the two factors represented a poor prognostic factor. This study proposes positivity of MMP-7 in peritoneal cavity as a novel biomarker for predicting disease recurrence in patients with CRC.

Abstract
BACKGROUND Anastomotic leaks after restorative resections for rectal cancer may lead to worse long-term outcomes. OBJECTIVE The purpose of this study was to evaluate the best current evidence assessing anastomotic leaks in rectal cancer resections with curative intent and their impact on survival and cancer recurrence. DATA SOURCES A meta-analysis was performed using MEDLINE, EMBASE, and Cochrane search engines for relevant studies published between January 1982 and January 2015. STUDY SELECTION Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology was used to screen and select relevant studies for the review using key words "colorectal surgery; colorectal neoplasm; rectal neoplasm" and "anastomotic leak." INTERVENTION Anastomotic leak groups were compared with nonanastomotic leak groups. MAIN OUTCOME MEASURES ORs were calculated from binary data for local recurrence, distant recurrence, and cancer-specific mortality. A random-effects model was then used to calculate pooled ORs with 95% CIs. RESULTS Eleven studies with 13,655 patients met the inclusion criteria. This included 5 prospective cohort and 6 retrospective cohort studies. Median follow-up was 60 months. Higher cancer-specific mortality was noted in the leak group with an OR of 1.30 (95% CI, 1.04-1.62; p < 0.05). Local recurrences were more likely in rectal cancer resections complicated by anastomotic leaks (OR = 1.61 (95% CI, 1.25-2.09); p < 0.001). Distant recurrence was not more likely in the anastomotic leak group (OR = 1.07 (95% CI, 0.87-1.33); p = 0.52). LIMITATIONS All 11 studies are level 3 evidence cohort studies. Additional sensitivity analyses were performed to minimize cross-study heterogeneity. CONCLUSIONS Anastomotic leaks after restorative resections for rectal cancer adversely impact cancer-specific mortality and local recurrence.

Abstract
PRL-3 genomic copy number is increased in colorectal cancer (CRC), and PRL-3 expression is closely associated with lymph node and liver metastasis of CRC. However, the clinical significance of PRL-3 genomic gain for CRC remains obscure. Here, PRL-3 genomic status in 109 primary CRC tumors and in 44 CRC tumors that had metastasized to the liver, was quantified using real time PCR. Association of PRL-3 genomic status with clinicopathological factors and prognosis was assessed in detail. PRL-3 genomic gain was identified in 31 primary CRC (27.4 %) and was more frequently seen in stage III than in stage II (p = 0.025). Among the clinicopathological factors assessed, PRL-3 genomic gain was significantly associated with poorly differentiated histology (p = 0.0039). Moreover, CRC patients with PRL-3 genomic gain exhibited poorer prognosis than those with no gain in stage II-IV CRC (p = 0.017). PRL-3 genomic gain was identified in 18 (41 %) of the liver metastasis tumors, and this frequency of gain was significantly increased as compared to that of the corresponding primary CRCs (11 %) (p = 0.001). Our findings suggested that PRL-3 genomic gain may represent an aggressive phenotype of primary CRC, and may associate with liver metastasis.

Abstract
BACKGROUND AND OBJECTIVES The impact of postoperative complications on long-term outcome has been reported in several types of malignancies. However, it is unclear why postoperative complications affect long-term outcome. The aim of this study is evaluating whether postoperative complication occurrence or C-reactive protein (CRP) elevation better reflects long-term outcome in gastric cancer patients. METHODS This study included 305 patients who underwent curative surgery for pT2-T4b gastric cancer. Patients were divided into two groups based on the peak CRP value (CRPmax): low (<12 mg/dl) and high CRPmax (≥ 12 mg/dl). A multivariate analysis was conducted to identify independent prognostic factors for recurrence-free survival (RFS). RESULTS Postoperative complications (≥ Grade II) occurred in 86 of 305 patients (28.2%). Although CRP elevation (P = 0.001) and postoperative complication occurrence (P = 0.045) was each significantly associated with RFS in the univariate analysis, multivariate analysis identified CRP elevation (P = 0.017) but not complication occurrence (P = 0.682) as an independent prognostic factor. Among patients without complications, those in the high CRPmax group had significantly worse RFS than those in the low CRPmax group (P = 0.004). CONCLUSIONS CRP elevation is a more reliable indicator of survival after gastric cancer surgery than postoperative complication occurrence. Surgeons should minimize the postoperative inflammatory response to improve prognosis.

Abstract
BACKGROUND We assessed the impact of complications on recurrence and survival after curative gastric cancer resection. METHODS Patients undergoing R0 resections between 1990 and 2009 were identified in a prospectively maintained database and were categorized by presence of any complication Clavien-Dindo (CD) ≥ II, sepsis or intra-abdominal sepsis. Cox regression analyses to relate complications and clinico-pathological variables to time to recurrence (TTR) and overall survival (OS) were performed. RESULTS A total of 271 patients were included with a median follow-up of 149.9 months (range 140.1-159.9). Complications CD ≥ II occurred in 162 (59.8%) patients, sepsis in 66 (22.5%), and intra-abdominal sepsis in 37 (13.6%). Recurrence developed in 88 (32.4%) patients. Independent predictors of short TTR were pTNM stage (IIIB-IIIC vs. IA-IIA) (hazard ratio [HR] = 37.55, 95% confidence interval [CI] 17.57-80.24; p < 0.001), D1 lymphadenectomy (HR = 3.14, 95% CI 1.94-5.07; p < 0.001), and male gender (HR = 1.65, 95% CI 1.06-2.57; p = 0.026). pTNM stage (IIIB-IIIC vs. IA-IIA, HR = 10.28, 95% CI 6.51-16.23; p < 0.001), male gender (HR = 1.64, 95% CI 1.17-2.31; p = 0.005), age (HR = 1.03, 95% CI 1.02-1.05; p < 0.001), and adjuvant therapy (HR = 0.55, 95% CI 0.37-0.83; p = 0.004) were identified as independent predictors of OS.. CONCLUSIONS Evidence provided by this study does not support a negative impact of postoperative complications CD ≥ II, sepsis, and intra-abdominal sepsis on the oncologic outcome after curative gastric cancer resection.

Abstract
OBJECTIVE The aim of this study was to investigate the effect of postoperative peritoneal infection on proliferation, migration, and invasion capacities of cancer cells lines in vitro after surgery for colorectal cancer. BACKGROUND Anastomotic leakage is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may enhance tumor progression features of residual cancer cells. METHODS Prospective matched cohort study. Patients undergoing surgery for colorectal cancer with curative intent (January 2008-March 2012) were included. Patients who had an anastomotic leak or intra-abdominal abscess were included in the infection group (n=47). For each case patient, another patient with an uncomplicated postoperative course was selected for the control group (n=47).In vitro treatments on cancer cell lines (MDA-MB-231 and SW620) were performed using baseline and postoperative serum and peritoneal fluid samples to determine cell proliferation and cell migration/invasion activities. RESULTS Postoperative peritoneal fluid from infected patients enhanced both cell migration (infection: 140±85 vs control: 94±30; P=0.016) and cell invasion (infection: 117±31 vs control: 103±16; P=0.024) capacities of cancer cell lines. With serum samples, these effects were only observed in cell migration assays (infection: 98±28 vs control: 87±17; P=0.005). Some minor activation of cell proliferation was observed by treatment with serum from infection group. Two-year cumulative disease-free survival was significantly lower in patients with postoperative peritoneal infection (infection: 77.6% vs control: 90.6%; P=0.032). CONCLUSIONS Our results suggest that postoperative peritoneal infection enhances the invasive capacity of residual tumor cells after surgery, thus facilitating their growth to recurrent tumors.

Diverting ileostomy in colorectal surgery: when is it necessary? Langenbecks Arch Surg 2015; 400:145-52.

Abstract
PURPOSE The role of fecal diversion using a loop ileostomy in patients undergoing rectal resection and anastomosis is controversial. There has been conflicting evidence on the perceived benefit vs. the morbidity of a defunctioning stoma. This is a review of the relevant surgical literature evaluating the risks, benefits, and costs of constructing a diverting ileostomy in current colorectal surgical practice. METHODS Retrospective and prospective articles spanning the past 50 years were reviewed to identify the definition of an anastomotic leak (AL), evaluate risk factors for AL, and assess methods of evaluation of the anastomosis. We then pooled the evidence for and against fecal diversion, the incidence and consequences of stomal complications, and the evidence comparing loop ileostomy vs. loop colostomy as the optimal method of fecal diversion. RESULTS Evidence shows that despite the fact that fecal diversion does not decrease postoperative mortality, it does significantly decrease the risk of anastomotic leak and the need for urgent reoperation when a leak does occur. Diverting stomas are a low-risk surgical procedure from a technical standpoint but carry substantial postoperative morbidity that can greatly hamper patients' quality of life and recovery. High-risk patients such as those with low colorectal anastomoses (<10 cm from anal verge), colo-anal anastomoses, technically difficult resections, malnutrition, and male patients seem to reap the greatest benefit from fecal diversion. CONCLUSIONS Fecal diversion is recommended as a selective tool to protect or ameliorate an anastomotic leak after a colorectal anastomosis. It is most beneficial when used selectively in high-risk patients with low pelvic anastomoses that are at an increased risk for AL. New tools are needed to identify patients at high risk for anastomotic failure after anterior resection.

Abstract
BACKGROUND The influence of anastomotic leak on local recurrence and survival remains debated in rectal cancer. METHODS This was a multicentre observational study using data from the Spanish Rectal Cancer Project database. Demographics, American Society of Anesthesiologists classification, tumour location, stage, use of defunctioning stoma, administration of neoadjuvant and adjuvant treatment, invasion of circumferential resection margin, quality of mesorectal excision and anastomotic leakage were recorded. Anastomotic leak was defined as an anastomotic event requiring surgical intervention or interventional radiology, including pelvic abscesses without radiological evidence of leakage and early rectovaginal fistulas. Variables associated with oncological outcome were assessed by multivariable Cox regression analysis. RESULTS A total of 1181 consecutive patients were included. Rates of anastomotic leak and 30-day postoperative mortality were 9·4 and 2·4 per cent respectively. Data from 1153 patients were analysed after a median follow-up of 5 years. Cumulative rates of local recurrence, overall recurrence, overall survival and cancer-specific survival were 4·9, 19·4, 77·5 and 84·7 per cent respectively. In the multivariable regression analysis, anastomotic leakage was not associated with local recurrence (hazard ratio (HR) 0·80, 95 per cent c.i. 0·28 to 2·26; P = 0·669), overall recurrence (HR 1·14, 0·70 to 1·85; P = 0·606), overall survival (HR 1·10, 0·73 to 1·65; P = 0·648) or cancer-specific survival (HR 1·23, 0·75 to 2·02; P = 0·421). CONCLUSION Anastomotic leak after low anterior resection did not affect oncological outcomes in these patients.

Abstract
BACKGROUND The prognosis of patients with peritoneally metastasized colorectal cancer has improved significantly with the introduction of cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (CRS + HIPEC). Although a macroscopically complete resection is achieved in nearly every patient, recurrence rates are high. This study aims to identify risk factors for early recurrence, thereby offering ways to reduce its occurrence. METHODS All patients with colorectal peritoneal carcinomatosis treated with CRS + HIPEC and a minimum follow-up of 12 months, in April 2014, were analyzed. Patient data were compared between patients with or without recurrence within 12 months after CRS + HIPEC. Risk factors were determined using logistic regression analysis. Postoperative complications were graded according to the serious adverse events (SAEs) score, with grade 3 or higher indicating complications requiring intervention. RESULTS A complete macroscopic cytoreduction was achieved in 96 % of all patients treated with CRS + HIPEC. Forty-six of 133 patients (35 %) developed recurrence within 12 months. An SAE ≥3 after CRS + HIPEC was the only significant risk factor found for early recurrence (odds ratio 2.3; p = 0.046). Median survival in the early recurrence group was 19.3 months compared with 43.2 months in the group without early recurrence (p < 0.001). Patients with an SAE ≥3 showed a reduced survival compared with patients without such complications (22.1 vs. 31.0 months, respectively; p = 0.02). CONCLUSIONS Early recurrence after CRS + HIPEC is associated with a significant reduction in overall survival. This study identifies postoperative complications requiring intervention as the only significant risk factor for early recurrence, independent of the extent of peritoneal disease, highlighting the importance of minimizing the risk of postoperative complications.

Abstract
BACKGROUND Anastomotic leakage is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. The aim was to investigate the inflammatory and angiogenic responses in patients undergoing surgery for colorectal cancer who had postoperative intra-abdominal infection, and to compare the results with patients without complications. METHODS Consecutive patients undergoing surgery for colorectal cancer with curative intent were included. Patients who had an anastomotic leak or intra-abdominal abscess were included in the infection group and matched with patients who had an uncomplicated postoperative course. IL-6 and VEGF were measured in serum and peritoneal fluid. RESULTS Serum concentration of IL-6 was higher in the infection group (n = 30) compared with the control group (n = 30) on day 4 (infection: 42.3 [27.6-1473.2] versus control: 0.6 [0.6-17.1] pg/ml; p = 0.008). IL-6 in peritoneal fluid was higher in the infection group at 48 h and day 4 (infection: 1000.2 [995.4-1574.0] versus control: 90.3 [35.2.6-106.1] pg/ml; p = 0.001). Serum VEGF was higher in the infection group on day 4 (infection: 1128.6 [427.3-10000.0] versus control: 438.3 [214.1-677.6] pg/ml; p = 0.001). Peritoneal VEGF concentration was higher in the infection group at 48 h and day 4 (infection: 10000.0 [2563.0-10000.0] versus control: 477.8 [313.5-814.4] pg/ml; p = 0.001). Two-year recurrence rate was higher in patients with infection (infection: 30% versus control: 4%; p = 0.001). CONCLUSIONS Intra-abdominal infection increases IL-6 and VEGF after surgery for colorectal cancer. Amplification of inflammation and angiogenesis might be one of the mechanisms responsible for the higher recurrence rate observed in patients with anastomotic leakage or intra-abdominal abscess.

Neoadjuvant chemoradiation therapy using concurrent S-1 and irinotecan in rectal cancer: impact on long-term clinical outcomes and prognostic factors. Int J Radiat Oncol Biol Phys 2014; 89:547-55. [PMID: 24929164 DOI: 10.1016/j.ijrobp.2014.03.007] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2013] [Revised: 02/27/2014] [Accepted: 03/06/2014] [Indexed: 01/08/2023]
Abstract
PURPOSE To assess the long-term outcomes of patients with rectal cancer who received neoadjuvant chemoradiation therapy (NCRT) with concurrent S-1 and irinotecan (S-1/irinotecan) therapy. METHODS AND MATERIALS The study group consisted of 115 patients with clinical stage T3 or T4 rectal cancer. Patients received pelvic radiation therapy (45 Gy) plus concurrent oral S-1/irinotecan. The median follow-up was 60 months. RESULTS Grade 3 adverse effects occurred in 7 patients (6%), and the completion rate of NCRT was 87%. All 115 patients (100%) were able to undergo R0 surgical resection. Twenty-eight patients (24%) had a pathological complete response (ypCR). At 60 months, the local recurrence-free survival was 93%, disease-free survival (DFS) was 79%, and overall survival (OS) was 80%. On multivariate analysis with a proportional hazards model, ypN2 was the only independent prognostic factor for DFS (P=.0019) and OS (P=.0064) in the study group as a whole. Multivariate analysis was additionally performed for the subgroup of 106 patients with ypN0/1 disease, who had a DFS rate of 85.3%. Both ypT (P=.0065) and tumor location (P=.003) were independent predictors of DFS. A combination of these factors was very strongly related to high risk of recurrence (P<.0001), which occurred most commonly in the lung. CONCLUSIONS NCRT with concurrent S-1/irinotecan produced high response rates and excellent long-term survival, with acceptable adverse effects in patients with rectal cancer. ypN2 is a strong predictor of dismal outcomes, and a combination of ypT and tumor location can identify high-risk patients among those with ypN0/1 disease.
