Abstract
PURPOSE This study aimed to determine the best treatment for acute left-sided malignant colonic obstruction (ALMCO) among emergency surgery (ES), self-expanding metallic stent (SEMS), transanal drainage tube (TD), and decompressive stoma (DS). METHOD Articles that compared two or more treatments of ALMCO were searched from PubMed, Cochrane Library, and Embase. Network meta-analyses were performed to calculate the outcomes of primary anastomosis, stoma creation, morbidity, mortality, and 5-year survival. RESULTS Fifty-one articles met inclusion criteria. TD was the optimal treatment in performing primary anastomosis [probability of ranking first (Pro-1) 0.96], while ES was the worst [probability of ranking fourth (Pro-4) 0.99]. More permanent stoma was formed in ES and TD groups than in SEMS and DS groups [OR (95%CI): TD vs SEMS: 4.12 (1.89, 9.45); TD vs DS: 3.39 (1.46, 8.75); ES vs DS: 2.55 (1.73, 4.17); SEMS vs ES: 0.33 (0.24, 0.42)]. More morbidity occurred in ES group than in SEMS group [OR (95%CI): ES vs SEMS: 1.44 (1.14, 1.82)]. Besides, SEMS was ranked first in avoiding infection (Pro-4 0.95). For in-hospital mortality, ES was ranked first (Pro-1 0.93). TD was ranked first in recurrence (Pro-1 0.97) and metastasis (Pro-1 0.98). There was no discrepancy in 5-year overall and disease-free survival among all strategies. CONCLUSION SEMS as a bridge to surgery reduces stoma formation, and morbidity especially the infection rate with relatively great oncological outcomes. Therefore, SEMS should be recommended first for ALMCO in the medical center with experience and conditions.

Abstract
BACKGROUND Self-expanding metallic stent (SEMS) and trans-anal colorectal tube (TCT) are alternative treatments to conventional emergency surgery for non-right-sided obstructive colon cancer (NROCC). However, the one with better short- and long-term outcomes remains controversial. Thus, this multicenter case-control study aimed to analyze and compare SEMS and TCT for NROCC. METHODS Patients with stage II/III NROCC who underwent surgery between January 2010 and December 2019 at either of the eight selected Japanese affiliate hospitals were, retrospectively, reviewed. Baseline characteristics between the SEMS and TCT groups were adjusted by propensity score (PS) matching. RESULTS Among 239 reviewed patients (SEMS: 76, TCT: 163), 180 were finally included in two well-balanced cohorts through PS: SEMS group (65 patients) and TCT group (115 patients). Technical success, clinical success, morbidity, and short-term mortality were not significantly different between the two groups. SEMS placement achieved significantly higher rates for primary resection/anastomosis without stoma (SEMS: 90.8% vs. TCT: 77.4%, p < 0.001) and laparoscopic surgery (SEMS: 64.6% vs. TCT: 43.5%, p < 0.001) than TCT placement. However, 5-year overall survival (SEMS: 83.7% vs. TCT: 86.4%; p = 0.822) and 5-year relapse-free survival (SEMS: 64.7% vs. TCT: 66.4%; p = 0.854) showed no significant differences between these groups. CONCLUSIONS Both SEMS and TCT revealed similar long-term outcomes, but SEMS placement was better in achieving primary resection/anastomosis and laparoscopic surgery in patients with stage II/III NROCC.

Long-term and short-term outcomes of laparoscopic versus open resection following tube decompression for obstructive colorectal cancer: a single-center retrospective study. Surg Today 2022; 52:1284-1291. [PMID: 35107649 DOI: 10.1007/s00595-022-02458-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Accepted: 11/29/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE The benefits of laparoscopic surgery over open surgery are well documented; however, the suitability of laparoscopic surgery for obstructive colorectal cancer is still controversial. The aim of this retrospective study was to compare the clinical benefits of laparoscopic surgery vs. open surgery for obstructive colorectal cancer after tube decompression. METHODS We analyzed the outcomes of patients who underwent laparoscopic surgery vs. open surgery for curative resection after tube decompression for obstructive colorectal cancer at our hospital between January, 2007 and March, 2018. RESULTS This study comprised 67 patients: 29 patients who underwent open surgery and 38 patients who underwent laparoscopic surgery. The morbidity within 30 days after surgery was comparable between the groups. The 3-year overall survival rates of the open and laparoscopic groups were 83.3 and 79.4%, respectively (p = 0.6244), and the 3-year disease-free survival rates were 59.3 and 71.2%, respectively (p = 0.3200). Multivariate analysis showed that nodal stage (p = 0.021) was an independent prognostic factor for OS and sex (p = 0.010) and side-ness (p = 0.048) were independent prognostic factors for DFS. CONCLUSION If adequate decompression is achieved, laparoscopic resection following tube decompression for obstructive colorectal cancer can be a safe alternative to open surgery.

Abstract
Background The prognosis of obstructive colorectal cancer (oCRC) is worse than that of nonobstructive colorectal cancer. However, no previous study has established an individualized prediction model for the prognosis of patients with oCRC. We aimed to screen the factors that affect the prognosis of oCRC and to use these findings to establish a nomogram model that predicts the individual prognosis of patients with oCRC. Methods This retrospective study collected data of 181 patients with oCRC from three medical hospitals between February 2012 and December 2017. Among them, 129 patients from one hospital were used as the training cohort. Univariate and multivariate analyses were used in this training cohort to select independent risk factors that affect the prognosis of oCRC, and a nomogram model was established. The other 52 patients from two additional hospitals were used as the validation cohort to verify the model. Results Multivariate analysis showed that carcinoembryonic antigen level (p = 0.037, hazard ratio [HR] = 2.872 [1.065–7.740]), N stage (N1 vs. N0, p = 0.028, HR = 3.187 [1.137–8.938]; N2 vs. N0, p = 0.010, HR = 4.098 [1.393–12.051]), and surgical procedures (p = 0.002, HR = 0.299 [0.139–0.643]) were independent prognostic factors of overall survival in patients with oCRC. These factors were used to construct the nomogram model, which showed good concordance and accuracy. Conclusion Carcinoembryonic antigen, N stage, and surgical method are independent prognostic factors for overall survival in patients with oCRC, and the nomogram model can visually display these results.

Comparison of the prognosis of four different treatment strategies for acute left malignant colonic obstruction: a systematic review and network meta-analysis. World J Emerg Surg 2021; 16:11. [PMID: 33736680 PMCID: PMC7977175 DOI: 10.1186/s13017-021-00355-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 02/23/2021] [Indexed: 02/07/2023] Open
Abstract
Background There is controversy regarding the efficacy of different treatment strategies for acute left malignant colonic obstruction. This study investigated the 5-year overall survival (OS) and disease-free survival (DFS) of several treatment strategies for acute left malignant colonic obstruction. Methods We searched for articles published in PubMed, Embase (Ovid), MEDLINE (Ovid), Web of Science, and Cochrane Library between January 1, 2000, and July 1, 2020. We screened out the literature comparing different treatment strategies. Evaluate the primary and secondary outcomes of different treatment strategies. The network meta-analysis summarizes the hazard ratio, odds ratio, mean difference, and its 95% confidence interval. Results The network meta-analysis involved 48 articles, including 8 (randomized controlled trials) RCTs and 40 non-RCTs. Primary outcomes: the 5-year overall survival (OS) and disease-free survival (DFS) of the CS-BTS strategy and the DS-BTS strategy were significantly better than those of the ES strategy, and the 5-year OS of the DS-BTS strategy was significantly better than that of CS-BTS. The long-term survival of TCT-BTS was not significantly different from those of CS-BTS and ES. Secondary outcomes: compared with emergency resection (ER) strategies, colonic stent-bridge to surgery (CS-BTS) and transanal colorectal tube-bridge to surgery (TCT-BTS) strategies can significantly increase the primary anastomosis rate, CS-BTS and decompressing stoma-bridge to surgery (DS-BTS) strategies can significantly reduce mortality, and CS-BTS strategies can significantly reduce the permanent stoma rate. The hospital stay of DS-BTS is significantly longer than that of other strategies. There was no significant difference in the anastomotic leakage levels of several treatment strategies. Conclusion Comprehensive literature research, we find that CS-BTS and DS-BTS strategies can bring better 5-year OS and DFS than ER. DS-BTS strategies have a better 5-year OS than CS-BTS strategies. Without considering the hospital stays, DS-BTS strategy is the best choice. Supplementary Information The online version contains supplementary material available at 10.1186/s13017-021-00355-2.

Abstract
Aberrant expression of microRNA-876-5p (miR-876-5p) is implicated in the progression of multiple human cancers. However, the potential role of miR-876-5p in colorectal cancer remains poorly understood. The purpose of the current study was to investigate the potential role of miR-876-5p in colorectal cancer. miR-876-5p expression was significantly downregulated in colorectal cancer tissues and cell lines compared with normal controls. Gain-of-function assays revealed that miR-876-5p overexpression effectively repressed the malignant behaviours of colorectal cancer cells, including cell proliferation, colony formation, and invasion. Bioinformatics analysis predicted that RAS protein activator like 2 (RASAL2), a potential oncogene for colorectal cancer, is a putative miR-876-5p target gene. A luciferase reporter assay confirmed that miR-876-5p directly binds to the 3'-untranslated region (UTR) of RASAL2. Furthermore, both RASAL2 messenger RNA (mRNA) and protein expression were negatively modulated by miR-876-5p in colorectal cancer cells. Notably, there was an inverse correlation between miR-876-5p and RASAL2 expression in colorectal cancer tissue specimens. Moreover, miR-876-5p was involved in regulating the activation of Yes-associated protein (YAP) signalling through inhibiting RASAL2. However, the miR-876-5p-mediated antitumour effect on colorectal cancer cells was partially reversed by restoring RASAL2 expression. Notably, miR-876-5p upregulation impeded the tumour growth of colorectal cancer cells in vivo in nude mice. Overall, these results demonstrated that miR-876-5p exerts an antitumour function in colorectal cancer by targeting RASAL2 to suppress YAP signalling activation. These findings highlight the importance of the miR-876-5p/RASAL2/YAP axis in colorectal cancer progression and suggest that miR-876-5p is a potential therapeutic target for treating colorectal cancer.

Abstract
Long non-coding RNAs (lncRNAs) have recently emerged as key regulators of the occurrence and progression of various human cancers, including colorectal cancer. However, the regulatory mechanism of lncRNAs in the tumorigenesis of colorectal cancer remains poorly understood. In this study, we aimed to elucidate the potential role of lncRNA HCG18 in colorectal cancer. Herein, we found that HCG18 expression was significantly upregulated in colorectal cancer tissues and cell lines. Knockdown of HCG18 significantly inhibited the growth and invasion of colorectal cancer cells, while its overexpression had the opposite effect. Moreover, HCG18 was identified as a sponge of miR-1271. Our results showed that knockdown of HCG18 markedly upregulated miR-1271 expression in colorectal cancer cells. Notably, HCG18 expression was inversely correlated with miR-1271 expression in colorectal cancer specimens. Further investigation revealed that HCG18 contributed to the enhancement of MTDH/Wnt/β-catenin signalling in colorectal cancer cells. The antitumour effect of HCG18 inhibition was significantly reversed by miR-1271 inhibition or MTDH overexpression. Overall, the results of our study demonstrate that HCG18 exerts a potential oncogenic function in colorectal cancer by enhancing MTDH/Wnt/β-catenin signalling via sponging of miR-1271, highlighting the importance of HCG18/miR-1271/ MTDH/Wnt/β-catenin signalling in the progression of colorectal cancer.

Pathological impact of transanal colorectal tube for obstructive colorectal cancer. Surg Endosc 2019; 34:4011-4018. [PMID: 31624940 DOI: 10.1007/s00464-019-07188-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Accepted: 10/01/2019] [Indexed: 01/10/2023]
Abstract
BACKGROUND Colorectal cancer (CRC) with acute colorectal obstruction (ACO) is an emergency. Transanal colorectal tube (TCT) use can be a safe single-stage surgery with laparoscopy-assisted colectomy; it offers long-term outcomes equivalent to emergency surgery for stage-II/III CRC with ACO. Self-expanding metallic stent use, another alternative, may have detrimental pathological and molecular effects, whereas the pathological impact of TCT placement remains unclear. We hypothesized that TCT placement might exert little damage on primary tumor. Hence, the current study analyzed the pathological impact of TCT placement for CRC with ACO compared to emergency surgery. METHODS Data from consecutive patients with stage-II/III distal CRC with ACO who underwent surgery between January 2007 and December 2015 were retrospectively reviewed at two Japanese affiliate hospitals. Inflammatory and malignant potential-related parameters were analyzed by a single blinded pathologist. We extracted mRNA from tumor tissues to analyze inflammatory cytokines. RESULTS Sixty-eight patients with stage-II/III distal CRC with ACO were identified (surgery: 25 patients; TCT: 43 patients). Baseline characteristics were well balanced between the two groups. TCT showed a significantly lower frequency of abscess (surgery vs TCT, 36.0% vs 11.6%; P = 0.017) and a lower tendency of pathological perforation (surgery vs TCT, 20.0% vs 4.7%, respectively; P = 0.091), compared to the surgery group. There were no significant intergroup differences in oncological factors, including perineural invasion (surgery vs TCT, 52.0% vs 62.8%; P = 0.383), microlymphatic involvement (surgery vs TCT, 52.0% vs 58.1%; P = 0.623), and microvascular involvement (surgery vs TCT, 32.0% vs 25.6%; P = 0.570). No significant intergroup differences were found in interleukin (IL)-6, IL-8, or IL-1β gene expression levels (P = 0.580, 0.250, 0.941). CONCLUSIONS TCT placement had no pathologically detrimental effects on the tumor or surrounding tissues and might be an attractive non-invasive strategy for cases of curative distal CRC with ACO.

Abstract
Background Colorectal cancer is one of the highly malignant cancers with a poor prognosis. The exact mechanism of colorectal cancer progression is not completely known. Recently, microRNAs (miRNAs, miRs) were suggested to participate in the regulation of multiple cancer development, including colorectal cancer. Methods MiR-4319 expression in colorectal cancer patient samples was detected by real-time polymerase chain reaction. MiR-4319 was knocked down in the colorectal cancer cells by siRNA transfection to study the role of miR-4319 in the cell cycle and proliferation of colorectal cancer cells. Results MiR-4319 expression was found to be inverse correlated with survival in colorectal cancer patients. Overexpression of miR-4319 markedly reduced the proliferation of colorectal cancer cells and altered cell cycle distribution. A further experiment showed that ABTB1 is the target gene of miR-4319. MiR-4319 was regulated by PLZF. Conclusion Our studies indicated that reduced expression of miR-4319 was correlated with poor prognosis in colorectal cancer patients; miR-4319 also suppressed colorectal cancer cell proliferation by targeting ABTB1. ABTB1 might become an excellent therapeutic target for colorectal cancer treatment.
