Abstract
PURPOSE The present study aimed to investigate the clinical implications of apical lymph node metastasis (ALNM) after curative resection of stage III colorectal cancer. METHODS A retrospective study was conducted of 1403 consecutive colorectal cancer patients who underwent surgical resection at a single institution between April 2008 and January 2020. The characteristics of ALNM, the recurrence status and the relapse-free survival (RFS) were examined. RESULTS The numbers of patients with stage ≤ I, II, III, and IV disease were 350, 437, 476, and 140 patients, respectively. Among these patients with stage III disease, ALNM was seen in 21 patients (4.4% of stage III patients). Among them, curative resection was performed in 19 patients. Recurrence was observed in 68% (13/19) of the patients with ALNM who received curative resection. The first sites of recurrence included the lymph nodes 53.8% (7/13), liver 30.8% (4/13), lung 15.4% (2/13), brain 7.7% (1/13), bone 7.7% (1/13), and peritoneum 7.7% (1/13). There was no significant difference in the RFS of patients with ALNM who were managed with or without adjuvant chemotherapy (P = 0.207). Furthermore, the RFS of the group managed without adjuvant chemotherapy and the group that received adjuvant chemotherapy with/without oxaliplatin did not differ to a statistically significant extent (P = 0.318). In stage III colorectal cancer patients with ALNM, recurrence was observed significantly more frequently in comparison to stage III colorectal cancer patients without ALNM (P = 0.007). The first site of recurrence in patients with ALNM was most frequently seen in the distant lymph nodes (P = 0.004). CONCLUSION Our findings suggest that ALNM is strongly associated with recurrence in the distant lymph nodes and that it may lead to the development of systemic disease. The current regimen for stage III colorectal cancer may therefore not be sufficient for patients with stage III ALNM.

Abstract
AIM The aim of this work is to describe a protocol and assess the feasibility of harvesting and analysing the mesocolic apical fragment (MAF) for the presence of central lymph node (LN) metastasis and extra lymphatic free tumour cells in a random subgroup extracted from a cohort of complete mesocolic excision colectomies with central vascular ligation. METHOD Forty-seven patients diagnosed with colorectal cancer were included. A 2/2 cm pyramid of tissue was cut around the central tie and sent for pathological examination. The MAF was sectioned into 16 slices. High-definition images were taken from the slices which were merged into a panoramic three-dimensional image of the MAF. The distribution of LNs in the MAF was quantified. Immunohistochemistry staining for cytokeratin 14 was used to identify isolated tumour cells and micrometastases in the extranodal tissue. RESULTS No tumoural cells migrating through the apical zone, outside of the LNs, were identified. Margins of resection, mesocolic tissue and LNs were all negative in the subgroup of ultrastaged MAFs. The number of examined central LNs varied between 0 and 24, with positive MAF LNs being identified only in pN2 stages. The rate of positive apical LNs in our cohort was 4.2% (n = 2). CONCLUSIONS The MAF can be easily extracted from standard specimens, allowing for accurate analysis of lymphatic and extra-nodal tumour cells on the central resection margins, in central LNs and in the apical mesocolic tissue. Future research on larger cohorts is required to establish if analysing the MAF has an impact on patient staging, prognosis and management.

Abstract
OBJECTIVE The purpose of this study was to perform a meta-analysis comparing the oncological, intraoperative and safety outcomes in laparoscopic rectal cancer surgery with and without preservation of the left colic artery (LCA). METHOD We searched several databases including PubMed, Web of Science, Cochrane Library, and Embase databases. This meta-analysis included randomized clinical trials, prospective, and retrospective comparative studies regarding high- or modified low-tie ligation of the inferior mesenteric artery in laparoscopic rectal cancer surgery. RESULTS Of 641 potentially eligible articles, 16 studies with 3050 participants met the eligibility criteria and were included in the meta-analysis. There was no significant difference in estimated blood loss (WMD -2.63, 95% CI -5.69 to 0.43; P = .09), the number of harvested lymph nodes (WMD -0.35, 95% CI -1.60 to 0.20; P = .50), the number of apical lymph node yield (WMD -0.19, 95% CI -0.52 to 0.13; P = .24), the number of apical lymph node metastasis (OR 0.76, 95% CI 0.40 to 1.45; P = .40), rate of conversion to open surgery (OR 0.74, 95% CI 0.50 to 1.09; P = .513), rate of urinary dysfunction (OR 1.39, 95% CI 0.71 to 2.74; P = .34), rate of recurrence and metastasis (OR 1.10, 95% CI 0.75 to 1.61; P = .64), 5-year survival rate (OR 0.89, 95% CI 0.67 to 1.18; P = .42). However, this meta-analysis demonstrated a statistically significant difference in operating time (WMD -9.92, 95% CI -15.49 to -5.84; P = .0005), rate of diverting stom (OR 1.42, 95% CI 1.06 to 1.92; P = .02), rate of anastomotic leakage (OR 2.673, 95% CI 1.91 to 3.62; P < .00001), time to first flatus (WMD 0.29, 95% CI 0.11 to 0.48; P = .002), time of hospitalization (WMD 0.64, 95% CI 0.14 to 1.15; P = .01) between the 2 surgical techniques. COCLUSION The available evidence suggests that preserving the left colic artery is a safe, effective technique for patients with laparoscopic rectal cancer. nique for patients with laparoscopic rectal cancer.

Abstract
OBJECTIVE To examine the independent prognostic value of ALN status in patients with stage III CRC. SUMMARY OF BACKGROUND DATA Early CRC staging classified nodal involvement by level of involved nodes in the operative specimen, including both locoregional and apical node status, in contrast to the American Joint Committee on Cancer/tumor nodes metastasis (TNM) system where tumors are classified by the number of nodes involved. Whether ALN status has independent prognostic value remains controversial. METHODS Consecutive patients who underwent curative resection for Stage III CRC from 1995 to 2012 at Concord Hospital, Sydney, Australia were studied. ALN status was classified as: (i) ALN absent, (ii) ALN present but not histologically involved, (iii) ALN present and involved. Outcomes were the competing risks incidence of CRC recurrence and CRC-specific death. Associations between these outcomes and ALN status were compared with TNM N status results. RESULTS In 706 patients, 69 (9.8%) had an involved ALN, 398 (56.4%) had an uninvolved ALN and 239 (33.9%) had no ALN identified. ALN status was not associated with tumor recurrence [adjusted hazard ratio (HR) 1.02, 95% confidence interval (CI) 0.84-1.26] or CRC-specific death (HR 1.14, CI 0.91-1.43). However, associations persisted between TNM N-status and both recurrence (HR 1.58, CI 1.21-2.06) and CRC-specific death (HR 1.59, CI 1.19-2.12). CONCLUSIONS No further prognostic information was conferred by ALN status in patients with stage III CRC beyond that provided by TNM N status. ALN status is not considered to be a useful additional component in routine TNM staging of CRC.

No.253 Lymph Nodes Metastasis in Left-Sided Colorectal Cancer Liver Metastasis (CRLM) Patients: Incidence and Prognosis. Clin Med Insights Oncol 2022; 16:11795549221084841. [PMID: 35342322 PMCID: PMC8943451 DOI: 10.1177/11795549221084841] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Accepted: 02/09/2022] [Indexed: 12/02/2022] Open
Abstract
Background: No.253 lymph node is the gateway to systemic metastasis for left-sided
colorectal cancer. However, the value of D3 resection is still
controversial. This study aimed to identify the incidence rate and
prognostic value of 253LN metastasis in patients with left-sided colorectal
cancer liver metastasis (CRLM) mainly through blood vessels and thus to
provide theoretical basis for 253LN resection. Methods: From February 2012 to February 2019, a total of 281 patients who underwent
curative resection for both primary and metastatic tumors were collected
retrospectively. The clinicopathological and genetic characteristics were
compared between 58 patients with positive 253LN and 223 patients with
negative. Relapse-free survival (RFS) and overall survival (OS) were
compared with Kaplan–Meier method. Cox regression analysis and a forest plot
were conducted for RFS. Results: The incidence of 253LN metastasis in left-sided CRLM was 20.64% (58/281).
Those with 253LN positive were T4 stage, N2 stage, and D1/D2 lymph nodes
metastatic. About 10.3% (8/78) 253LN positive patients were D1/D2 negative.
The 253LN metastasis was an independent risk factor for relapse after
curative surgery, but not for OS. Patients with 253LN metastasis had worse
RFS, especially in female, adenocarcinoma, poorly differentiated, pT3,
preoperative serum CA199 < 37 U/mL, bilobar liver metastasis, without
preoperative chemotherapy, KRAS, NRAS, or
BRAF wild type. Conclusion: The incidence of 253LN metastasis in left-sided CRLM is 20.64%, and skip
metastasis rate is 10.3%. The 253LN status is an independent prognostic risk
factor for RFS but not for OS after curative surgery. Routine resection of
253LN should be applied in curative surgery of left-sided CRLM.

Current Perspectives on the Importance of Pathological Features in Prognostication and Guidance of Adjuvant Chemotherapy in Colon Cancer. Curr Oncol 2022; 29:1370-1389. [PMID: 35323316 PMCID: PMC8947287 DOI: 10.3390/curroncol29030116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 02/17/2022] [Accepted: 02/22/2022] [Indexed: 12/15/2022] Open
Abstract
There is not a clear consensus on which pathological features and biomarkers are important in guiding prognosis and adjuvant therapy in colon cancer. The Pathology in Colon Cancer, Prognosis and Uptake of Adjuvant Therapy (PiCC UP) Australia and New Zealand questionnaire was distributed to colorectal surgeons, medical oncologists and pathologists after institutional board approval. The aim of this study was to understand current specialist attitudes towards pathological features in the prognostication of colon cancer and adjuvant therapy in stage II disease. A 5-scale Likert score was used to assess attitudes towards 23 pathological features for prognosis and 18 features for adjuvant therapy. Data were analysed using a rating scale and graded response model in item response theory (IRT) on STATA (Stata MP, version 15; StataCorp LP). One hundred and sixty-four specialists (45 oncologists, 86 surgeons and 33 pathologists) participated. Based on IRT modelling, the most important pathological features for prognosis in colon cancer were distant metastases, lymph node metastases and liver metastases. Other features seen as important were tumour rupture, involved margin, radial margin, CRM, lymphovascular invasion and grade of differentiation. Size of tumour, location, lymph node ratio and EGFR status were considered less important. The most important features in decision making for adjuvant therapy in stage II colon cancer were tumour rupture, lymphovascular invasion and microsatellite instability. BRAF status, size of tumour, location, tumour budding and tumour infiltrating lymphocytes were factored as lesser importance. Biomarkers such as CDX2, EGFR, KRAS and BRAF status present areas for further research to improve precision oncology. This study provides the most current status on the importance of pathological features in prognostication and recommendations for adjuvant therapy in Australia and New Zealand. Results of this nationwide study may be useful to help in guiding prognosis and adjuvant treatment in colon cancer.

The prognostic significance of apical lymph node metastasis in patients with high-risk stage III colon cancer. Sci Rep 2022; 12:2059.

Abstract
The effect of apical lymph node (APN) metastasis on the prognosis of colon cancer is unknown. The present study investigated the impact of APN metastasis on the prognosis of the patients with high-risk stage III colon cancer. This retrospective multi-institutional study included patients with pathological high-risk stage III colon cancer who underwent surgery between April 2009 and December 2014. Clinicopathological factors were examined by univariate and multivariate analyses to clarify independent risk factors for overall survival (OS) and relapse-free survival (RFS). A total of 185 patients were collected. The 5-year OS rates of patients with and without APN metastasis were 35.0% and 72.1%, respectively (p = 0.0014). The 5-year RFS rates of patients with and without APN metastasis was 16.2% and 57.2%, respectively (p = 0.0002). The rate of distant metastasis in patients with APN metastasis was significantly higher than that in patients without APN metastasis (68.8% vs. 36.7%, p = 0.012). The univariate analysis revealed that the differentiation, lymph node ratio, and APN metastasis were significantly associated with 5-year OS, and the preoperative CEA and CA19-9 levels and APN metastasis were significantly associated with 5-year RFS. The multivariate analysis showed that APN metastasis was an independent risk factor for 5-year OS and RFS. APN metastasis may be independently associated with the prognosis of patients with high-risk Stage III colon cancer.

Exploring Central Vascular Anatomy With Axial Computed Tomography During Surgery for Sigmoid Colon and Rectal Cancer: New Insights Into the Anatomical Relationship Between the Inferior Mesenteric Artery and the Duodenum. Front Surg 2021; 8:785313. [PMID: 34966777 PMCID: PMC8710449 DOI: 10.3389/fsurg.2021.785313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 11/23/2021] [Indexed: 11/13/2022] Open
Abstract
Background: In some individuals, the inferior mesenteric artery (IMA) originates from the aorta above the lower edge of the duodenum. This anatomical feature has rarely been reported but may be important in guiding central vascular ligation and lymph node dissection in colorectal surgery. This retrospective study aimed to explore the anatomical relationship between the IMA and the duodenum and evaluate its potential impact on the efficacy of D3 lymph node dissection. Methods: A total of 439 patients undergoing laparoscopic colorectal surgery at the Department of General Surgery, Qilu Hospital of Shandong University, were retrospectively enrolled. Clinical data from axial computed tomography (CT) scans were collected and analysed. Results: In 27.69% of patients, the IMA originated at or above the lower edge of the duodenum (median distance: −8 mm). These patients were characterised by a shorter superior mesenteric artery to aortic bifurcation distance, a superiorly located IMA origin, and a greater distance between the IMA and both the left colic artery and the inferior mesenteric vein. The number of harvested lymph nodes was not significantly associated with the distance between the IMA and the duodenum (P = 0.858). Conclusions: Preoperative axial CT scans can provide a great deal of information regarding central vascular anatomy in the context of sigmoid colon and rectal cancer surgery. Nearly one-third of patients have the IMA originating at or above the duodenum. Whether this anatomical feature affects D3 lymph node dissection warrants further investigation.

Abstract
The prognostication of colorectal cancer (CRC) has traditionally relied on staging as defined by the Union for International Cancer Control (UICC) and American Joint Committee on Cancer (AJCC) TNM staging classifications. However, clinically, there appears to be differences in survival patterns independent of stage, suggesting a complex interaction of stage, pathological features, and biomarkers playing a role in guiding prognosis, risk stratification, and guiding neoadjuvant and adjuvant therapies. Histological features such as tumour budding, perineural invasion, apical lymph node involvement, lymph node yield, lymph node ratio, and molecular features such as MSI, KRAS, BRAF, and CDX2 may assist in prognostication and optimising adjuvant treatment. This study provides a comprehensive review of the pathological features and biomarkers that are important in the prognostication and treatment of CRC. We review the importance of pathological features and biomarkers that may be important in colorectal cancer based on the current evidence in the literature.

Early surgery after bridge-to-surgery stenting for malignant bowel obstruction is associated with better oncological outcomes. Surg Endosc 2021; 35:7120-7130. [PMID: 33433675 DOI: 10.1007/s00464-020-08232-w] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Accepted: 12/03/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND Placement of self-expanding metal stents has been increasingly adopted as a bridge to surgery in patients presenting with obstructed left-sided colorectal cancers. The optimal bridging time has yet to be widely established, hence this retrospective study aims to determine the optimal bridging time to elective surgery post endoluminal stenting. PATIENTS AND METHODS All patients who underwent colorectal stenting for large bowel obstruction in a single, tertiary hospital in Singapore between January 2003 and December 2017 were retrospectively identified. Patients' baseline demographics, tumour characteristics, stent-related complications, intra-operative details, post-operative complications and oncological outcomes were analysed. RESULTS Of the 53 patients who successfully underwent colonic stenting for malignant left sided obstruction, 33.96% of patients underwent surgery within two weeks of stent placement while 66.04% of patients underwent surgery after 2 weeks of stent placement. Univariate analysis between both groups did not demonstrate significant differences in postoperative complications and stoma formation. Significant differences were observed between both groups for stent complications (38.89% vs 8.57%, p = 0.022), on-table decompression (38.89% vs 2.86%, p = 0.001) and systemic recurrence (11.11% vs 40.00%, p = 0.030). Increased bridging interval to surgery (OR 13.16, CI 1.37-126.96, p = 0.026) was a significant risk factor for systemic recurrence on multivariate analysis. CONCLUSIONS Patients undergoing definitive surgery within 2 weeks of colonic stenting may have better oncological outcomes without compromising on postoperative outcomes. Further prospective studies are required to compare outcomes between emergency surgery and different bridging intervals.

[PMID: 34531032 DOI: 10.1016/j.surg.2021.08.023] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 08/13/2021] [Accepted: 08/16/2021] [Indexed: 12/26/2022]
Abstract
BACKGROUND Inferior mesenteric artery lymph node (station 253 node) metastasis occurs in approximately 0.3% to 13.9% of rectal cancer patients. This study examined whether carbon nanoparticles could aid in harvesting more station 253 nodes and evaluated the relationship between the number of station 253 nodes retrieved and station 253 node metastasis. METHOD A total of 480 consecutive rectal cancer patients were enrolled in this prospective cohort study between August 2014 and October 2018. Ninety-one patients (18.96%) received a preoperative submucosal injection of carbon nanoparticles (CN+ group), and 389 patients did not receive an injection (CN- group). The number of lymph node retrievals was analyzed, and the relevant risk factors for station 253 node metastasis were identified using univariate and multivariate analyses. RESULTS The mean number of station 251, 252, and 253 lymph nodes and total lymph nodes retrieved in the CN+ group were higher than that retrieved in the CN- group. The percentage of patients with ≥4 station 253 nodes retrieved (54.0% vs 28.3%, P = .004) were higher in the CN+ group than in the CN- group. Retrieval of ≥4 station 253 nodes was an independent risk factor for station 253 node metastasis (OR: 2.40, 95% CI: 1.22-4.74, P = .012). CONCLUSION The preoperative submucosal injection of carbon nanoparticles was helpful for increasing the number of station 253 nodes harvested, and a minimum of 4 examined station 253 nodes was necessary for standard D3 lymph node dissection in rectal cancer.

Abstract
BACKGROUND Unlike the tumor nodes metastasis (TNM) lymph node classification, based solely on counts of nodal metastases, the Japanese system of classifying colorectal carcinoma (CRC) focuses on regional lymph node spread. In this study, we explored the prognostic utility of inferior mesenteric artery (IMA) apical lymph node (APN) metastasis. PATIENTS AND METHODS This was a retrospective study of patients with stage III left-sided CRC. All enrollees were subjected to D3 resection between April 2007 and December 2016 at the International Medical Center of Saitama Medical University and then stratified by histologic presence (APN+ group) or absence (APN- group) of tumor in APNs examined postoperatively. Ultimately, propensity score matching was invoked (1:2) and COX regression analysis was conducted, determining group rates of relapse-free survival (RFS) and cancer-specific survival (CSS). RESULTS A total of 498 patients were studied, grouped as APN+ (19/498, 3.8%) or APN- (479/498, 96.2%). Prior to matching, the APN+ (vs. APN-) group showed significantly more lymphatic involvement (73.7% vs. 47.8%; p=0.023), deep (T3/T4) tumor infiltration (100% vs. 78.9%; p=0.024), and nodal metastasis (N2: 84.2% vs. 27.6%; p<0.001). In addition, para-aortic nodal recurrences were significantly increased (15.7% vs. 2.0%; p<0.001), conferring worse RFS (p<0.001) and CSS (p=0.014) rates. Once baseline factors were matched, the two groups appeared similar in RFS (p=0.415) and CSS (p=0.649). Multivariate regression analysis indicated that elevated carcinoembryonic antigen (CEA) level and deep tumor infiltration were independent risk factors for RFS, whereas postoperative complications and tumor-positive node counts were independent risk factors for CSS. APN+ status was not a significant risk factor for RFS or CSS. CONCLUSION APN positivity may thus constitute a regional rather than systemic manifestation. The TNM staging based on the number of metastatic lymph nodes seems to be more reasonable than the regional lymph node classification method.

Abstract
Background This study aimed to explore potential risk factors for 253 lymph node metastasis, and to identify the prognostic impact of 253 lymph node metastasis in colorectal cancer patients. Methods A retrospective study was conducted of 391 colorectal cancer patients who underwent surgical treatments that included 253 lymph node dissection. Clinicopathological features, molecular indexes and 1-year overall survival rates were analyzed. Results Univariate analyses revealed the following risk factors for 253 lymph node metastasis: high preoperative levels of CEA, large tumour max diameters, and numbers of harvested lymph nodes, presence of vessel carcinoma emboli, low level of MSH6 and MLH1 immunohistochemical staining intensity. Multivariate analysis showed that elevated MLH1 immunohistochemical staining intensity was an independent protective factor for 253 lymph node metastasis (OR: 0.969, 95% CI 0.945, 0.994, P = 0.015). A significant difference was found in 1-year overall survival rate between 253 lymph node-positive and lymph node-negative colorectal cancer patients (88.9% vs.75.0%, P < 0.001). Conclusions 253 lymph node-positive colorectal cancer patients had a worse prognosis than the 253 lymph node-negative patients. 253 lymph node dissection may improve the prognosis of colorectal cancer patients with high risk factors for 253 lymph node metastasis.

Abstract
AIM Main lymph node (LN) metastasis dissected with a high vascular tie at the root of the feeding artery is a poor prognostic factor in colorectal cancer (CRC). However, the effects of horizontal spread on recurrence after curative resection remain unclear. The purpose of this study is to evaluate the relationship between the horizontal spread of LN metastasis and recurrence in CRC. METHOD In this retrospective study, 189 CRC patients (98 men, 91 women) who underwent curative resection at our hospital from 2003 to 2018 and had only pericolic LN metastasis were divided into two groups: patients with LN metastasis beside the tumour only (T group, n = 121) and those with LN metastasis with horizontal spread (S group, n = 68) (mean follow-up period 50.9 ± 34.1 months). The primary outcome was recurrence-free survival (RFS). We investigated the correlation between clinicopathological background factors and recurrence using Cox regression analysis. RESULTS Fewer than three LN metastases (N1) were found in 157 patients (107 T group, 50 S group), and four or more metastases (N2a) were found in 32 patients (14 T group, 18 S group). Univariate analyses revealed significantly shorter RFS in the S group [hazard ratio (HR) 1.95, 95% CI 1.07-3.55; p = 0.03). Multivariate analyses revealed that horizontal spread is an independent risk factor for recurrence (HR 1.95, 95% CI 1.05-3.68; p = 0.03). CONCLUSION Although further investigation is needed, horizontal spread of LN metastasis is a prognostic factor for recurrence in Stage III CRC.

Abstract
AIM Surgeons have concerns whether high ligation (HL) of the inferior mesenteric artery (IMA) increases the incidence of anastomotic leakage (AL). This meta-analysis aimed to evaluate the influence of HL of the IMA on AL compared with low ligation (LL). METHODS PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov databases were searched. Randomized controlled trial studies that compared HL with LL of the IMA in anterior resection for rectal cancer and reported AL outcomes were eligible for inclusion. The odds ratios and mean differences were analysed by a random-effects model. Trial sequential analysis was performed to minimize the risk of random errors. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence for outcomes. RESULTS Of the 531 records screened, five randomized controlled trials with 779 patients were selected for analysis. The pooled incidence of AL was 12.1% (95% Cl 7.77-18.26) in the HL group and 9.7% (95% Cl 5.79-15.82) in the LL group (OR 1.20, 95% CI 0.77-1.87, P = 0.42). In trial sequential analysis, the cumulative Z-score curve exceeded the futility boundary, although the required information size of 1060 had not been reached. The quality of evidence was judged to be high according to the GRADE approach. CONCLUSIONS This meta-analysis shows that HL of the IMA does not increase the incidence of AL in anterior resection for rectal cancer.

Abstract
OBJECTIVE The prognostic factors for patients with T1-2 colorectal cancer (CRC) after radical resection and the predictive value of lymph node distribution (LND) system compared with TNM system for these patients have not been well studied. METHODS From September 2009 and June 2016, a total of 541 consecutive patients with T1-2 CRC who accepted radical resection in two centers were included in this study. Their clinicopathological characteristics and prognosis were analyzed using univariate and multivariate Cox regression analyses. The predictive value of LND system for these patients were compared with the TNM system. RESULTS Univariate analysis revealed that patients' gender, tumor size, LNM and lymphovascular or nerve invasion were prognostic factors for the disease-free survival (DFS) (p < 0.05). Multivariate regression analysis confirmed the gender, LNM and lymphovascular or nerve invasion were independent prognostic factors for the DFS (p < 0.05). The LND system had a better predictive value than the TNM system in lymph node-positive T1-2 CRC patients (P = 0.026 vs p = 0.148). CONCLUSIONS The gender, LNM and lymphovascular or nerve invasion were independent prognostic factors for the patients with T1-2 CRC after radical resection. The LND system had a better predictive value than the TNM system in T1-2 CRC patients.

Abstract
BACKGROUND An oxaliplatin-based chemotherapy regimen improves the survival outcomes of patients with stage III colon cancer. However, its complications are well-known. OBJECTIVE The purpose of this study was to distinguish between the survival outcomes of patients who underwent curative resection for stage III colon cancer with oxaliplatin chemotherapy and those who underwent such resection without oxaliplatin chemotherapy. DESIGN This was a retrospective analytical study based on prospectively collected data. SETTINGS This study used data on patients who underwent surgery at our hospital between January 2010 and December 2014. PATIENTS A cohort of 254 consecutive patients who underwent curative resection for stage III colon cancer was included in this study. The patients were divided into 2 groups: patients with isolated pericolic lymph node metastasis (n = 175) and those with extrapericolic lymph node metastasis (n = 79). MAIN OUTCOME MEASURES Clinicopathologic features and 3-year survival outcomes were analyzed with and without oxaliplatin therapy in the pericolic lymph node group. RESULTS The pericolic lymph node group showed significantly improved overall survival compared with the extrapericolic lymph node group at a median follow-up of 48.5 months (95.8% vs 77.8%; p < 0.001). In contrast, there was no significant difference in overall survival (99.0% vs 92.0%; p = 0.137) and disease-free survival (89.1% vs 88.2%; p = 0.460) between the oxaliplatin and nonoxaliplatin subgroups of the pericolic lymph node group. Multivariate analysis showed that the administration of oxaliplatin chemotherapy to the pericolic lymph node group did not lead to a significant difference in the overall survival (p = 0.594). LIMITATIONS The study was limited by its retrospective design and single institutional data analysis. CONCLUSIONS This study suggests that the anatomic extent of metastatic lymph nodes could affect patient prognosis, and the effect of oxaliplatin-based adjuvant chemotherapy may not be prominent in stage III colon cancer with isolated pericolic lymph node metastasis.

Abstract
BACKGROUND The role of apical lymph node (APN) metastasis in colorectal cancer remains controversial. The main purpose of this study is to explore the prognostic value of APN metastasis in patients with right colon cancer. METHODS This is a retrospective study of patients with stage III right colon cancer between April 2007 and December 2016. Patients who underwent resection of right colon cancers with D3 lymph node dissection were divided into APN-positive (APN+) and APN-negative (APN-) groups according to the postoperative pathological presence or absence of APN metastasis. Relapse-free survival (RFS) and overall survival (OS) between groups were compared after Cox regression analysis and 1:1 propensity score matching (PSM). RESULTS A total of 254 patients were included in this study: 28 (11.0%) were APN+ and 226 (89.0%) were APN-. Before matching, the rates of elevated carcinoembryonic antigen (CEA), T3-4 tumor invasion, and N2 lymph node metastasis were significantly higher in the APN+ group (CEA ≥ 5 ng/mL, 53.6% vs. 37.6%, p < 0.001; T3-4, 92.9% vs. 85.4%, p < 0.001; N2 metastasis, 57.1% vs. 20.4%, p < 0.001), and APN+ tumors were associated with significantly higher postoperative relapse rates (39.3% vs. 21.2%; p = 0.03), especially with lung metastases (14.3% vs. 4.0%; p = 0.019), which conferred worse RFS (p = 0.013), although OS was similar (p = 0.078). However, after PSM, there were no apparent between-group differences in RFS (p = 0.29) or overall survival rate (p = 0.637). The Cox regression analysis indicated that lymphatic vessel infiltration and depth of invasion were independent risk factors for OS, while APN+ status was not a significant predictor for RFS or OS. CONCLUSIONS APN metastasis was not a prognostic indicator for RFS or OS in right colon cancer. However, APN+ patients with elevated CEA levels and deeper tumor invasion should be closely monitored for lung metastasis during postoperative follow-up.

Apical Lymph Nodes in the Distant Metastases and Prognosis of Patients with Stage III Colorectal Cancer with Adequate Lymph Node Retrieval Following FOLFOX Adjuvant Chemotherapy. Pathol Oncol Res 2019; 25:905-913. [PMID: 29299827 DOI: 10.1007/s12253-017-0381-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2017] [Accepted: 12/21/2017] [Indexed: 01/10/2023]
Abstract
The aim of the study was to assess apical lymph nodes (APNs) for predicting distant metastases in patients with stage III colorectal cancer (CRC) curatively treated with FOLFOX adjuvant chemotherapy and adequate lymph node retrieval. We investigated the correlation between APN metastasis and clinical outcomes. This retrospective study examined 97 patients. All patients were followed until death, loss to follow-up, or May 2017. Clinicopathological variables, including the APN status, were assessed. Multivariate logistic regression model was used to identify the independent risk factors for APN and distant metastases, and Cox proportional regression model was used to evaluate the association between APN metastasis and oncologic outcomes. Multivariate analyses revealed the N2 stage as an independent predictor of APN metastasis [P = 0.036; odds ratio (OR): 3.016; 95% confidence interval (CI): 1.076-8.499], while APN metastasis was an independent risk factor for distant metastases (P < 0.001; OR: 13.876; 95% CI: 3.815-50.475). Furthermore, APN metastasis was an independent risk factor for poorer disease-free survival (DFS) and overall survival (OS) (P < 0.001 and P = 0.005, respectively). The liver (31.6%) was the most common site of distant metastases in patients with APN metastases. APN metastasis is an important prognostic factor for node-positive CRC; it enhanced the distant metastases in patients with stage III CRC curatively treated with adequate lymph node retrieval following FOLFOX adjuvant chemotherapy. Therefore, for patients with stage III CRC involving APN metastasis, prospectively randomized trials are mandatory to investigate different therapeutic strategies in addition to conventional FOLFOX adjuvant chemotherapy.

Abstract
BACKGROUND The aim of this study was to investigate the prognostic value of D3 lymph node (TSLN) for the survival of patients with colorectal cancer. METHODS A total of 156 patients with R0 resected colorectal cancer were selected from 2011 to 2015 to carry out a retrospective study. The survival rate according to the groups of positive lymph node number (N: 1-3, N2: 4-6, N3: ≥7) and TSLN (TSLN [-], TSLN [+]) was analyzed. The influences of covariates on the 5-year overall survival (OS) and 5-year disease-free survival (DFS) were determined by the Cox proportional risk model of backward stepwise analysis. Kaplan-Meier survival analysis was used to draw survival curves between and within groups. RESULTS During the median follow-up period (44.0 months), the 5-year DFS rate and OS rate were 45.0% and 46.0%, respectively. Survival analysis of the TSLN group showed that the 5-year OS rate and 5-year DFS rate in the TSLN (+) group (20.0 and 16.2%, respectively) were significantly lower than those in the TSLN (-) group (68.3 and 51.6%, respectively) (P < 0.001). The 5-year OS rate and DFS rate of the TSLN (+) and TSLN (-) subgroups in the N1 group were 16.7%, 33.3%, 56.7%, and 55.7%, respectively (P < 0.001). Multivariate analysis showed that positive lymph node, TSLN, and Pathological T stage were independent prognostic factors of DFS and OS for 5 years. Patients in the TSLN (+) group had a poorer prognosis. CONCLUSIONS TSLN metastasis is an independent factor influencing the prognosis of patients, and patients with TSLN (+) have a poor prognosis. As an independent prognostic factor, this factor should be considered when evaluating the prognosis of patients.

Abstract
The definition of complete mesocolic excision (CME) for colon carcinomas revolutionized the way of colon surgery. This technique conquered the world starting from Erlangen. Nevertheless, currently new developments especially in minimally invasive surgery challenge CME to become settled as a standard of care. To understand the evolution of CME, anatomical details occurring during embryogenesis and their variations have to be considered. This knowledge is indispensable to transfer CME from an open to a minimally invasive setting. Conventional surgery for colon cancer (non-CME) has a morbidity of 12.1–28.5% and a 3.7% mortality risk vs. 12–36.4% morbidity and 2.1–3% mortality for open CME. The morbidity of laparoscopic CME is between 4 and 31% with a mortality of 0.5–0.9%. In robotic assisted surgery, morbidity between 10 and 25% with a mortality of 1% was published. The cancer-related survival after 3 and 5 years for open CME is respectively 91.3–95% and 90% vs. 87% and 74% for non-CME. For laparoscopic CME the 3- and 5-year cancer-related survival is 87.8–97% and 79.5–80.2%. In stage UICC III the 3- and 5-year cancer-related survival is 83.9% and 80.8% in the Erlangen data of open technique vs. 75.4% and 65.5–71.7% for laparoscopic surgery. For stage UICC III the 3- and 5-year local tumor recurrence is 3.8%. The published data and the results from Erlangen demonstrate that CME is safe in experienced hands with no increased morbidity. It offers an obvious survival benefit for the patients which can be achieved solely by surgery. Teaching programs are needed for minimally invasive CME to facilitate this technique in the same quality compared to open surgery. Passing these challenges CME will become the standard of care for patients with colon carcinomas offering all benefits of minimally invasive surgery and oncological outcome.

Abstract
BACKGROUND The decision of ligation at the origin of the inferior mesenteric artery (IMA) or below the origin of the left colic artery (LCA) has remained a dilemma for surgeons in colorectal cancer surgery. The available studies are controversial. The objective of this meta-analysis is to compare the predictive significance of high versus low ligation in colorectal cancer surgery. METHODS A literature search done using Medline, EMBASE, GoogleScholar, and references. A meta-analysis was performed to analyze the 5-year overall survival (OS) of the high and low ligation using hazard ratio (HR) and 95% confidence interval (CI). We further analyzed 2 subgroups considering the level of lymph nodes (LNs) extension. That is IMA positive (+ve) and negative (-ve) LNs. Survival differences were analyzed. RESULTS A total of 3119 patients in 5 cohorts were included in this meta-analysis. The pooled HR results showed significant OS benefit of high ligation than low ligation (HR; 0.77, 95% CI: 0.66-0.89) in the "IMA +ve" group with 33% decreased risk, while there is no statistical significance in the "IMA -ve" (HR 0.66, 95% CI: 0.30-1.46) and the "all cases" group (HR 0.69, 95% CI: 0.41-1.15). CONCLUSION The pooled data showed high ligation of IMA has a better survival benefit for the patients with IMA positive LNs. It signifies high ligation should be recommended for the advanced cases or with the suspected high risk of IMA lymphatic metastasis. The limited number of articles demands future high-powered, well-designed randomized controlled trials (RCTs) for the further reliable conclusion.

Inferior mesenteric artery lymph node metastasis in rectal cancer treated with neoadjuvant chemoradiotherapy: Incidence, prediction and prognostic impact. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2017; 43:85-91.

Abstract
AIM To assess the effect of neoadjuvant chemoradiotherapy (nCRT) on inferior mesenteric artery (IMA) nodal metastasis and identify predictors for IMA nodal metastasis in locally advanced rectal cancer (LARC) after nCRT. METHOD Propensity score matching of 1167 patients with LARC was performed. Clinicopathological predictors and survival rates were analyzed using univariate and multivariate analyses. RESULTS Compared to surgery alone, nCRT reduced the incidence of IMA nodal metastasis (before matching, 4.8% vs 9.1%, p = 0.004; after matching, 4.3% vs 10.1%, p = 0.002). Logistic regression analysis revealed that poorly differentiated (OR = 5.955, p < 0.001), tumors located above the peritoneal reflection (OR = 3.513, p = 0.005), and preoperative CEA levels ≧10 ng/ml (OR = 4.774, p = 0.005) were associated with IMA nodal metastasis. Time intervals to surgery ≧6 weeks were associated with fewer IMA nodal metastasis (OR = 0.274, p = 0.009).Over a median 40-month follow-up, the 3-year overall survival and disease-free survival rates were 63.0% and 43.1% in IMA-positive patients, respectively, which were significantly lower than the corresponding 89.0% and 82.4% rates in IMA-negative patients. Cox regression analysis revealed that IMA nodal metastasis was independently associated with unfavorable 3-year DFS. CONCLUSION nCRT reduced the incidence of IMA node metastasis. Tumors located above the peritoneal reflection, poorly differentiated, and higher preoperative CEA levels were associated with IMA nodal metastasis after nCRT. IMA lymph node dissection is beneficial to certain patients with IMA nodal metastases, and the oncologic benefit may be improved if IMA nodal metastasis can be predicted.

Abstract
In an effort to optimize further the surgical management of colon cancer, many groups have advocated extended lymphadenectomy as a strategy to improve completeness of resection and lymph node harvest. This review evaluates lymphadenectomy according to the definitions for extent of lymph node dissection based on the guidelines provided by the Japanese Society of Cancer of the Colon and Rectum and the contemporary concepts of complete mesocolic excision and central vascular ligation. The proposed benefits of a D3 or central nodal dissection along root vessels in colon cancer is improving accuracy of lymph node evaluation and ensuring complete removal of lymph nodes that may harbor undetected tumor cells or other undefined immunologic processes important for metastases. Metastasis to central lymph nodes occurs in 1 to 8% of patients with colon cancer and is most commonly seen in T3 and T4 tumors. Although central lymph node metastasis is associated with decreased survival after resection, resection of the nodes, when present, may confer a survival benefit analogous to resection of metastasis at distant sites. Current data support a standardized anatomic approach to colonic resection with complete resection of the mesocolic envelope and ligation at least to the D2 level.

Abstract
BACKGROUND There is currently no consensus on the significance of Japanese D3 lymph node dissection in low rectal cancer with inferior mesenteric lymph node (IMLN) metastasis. This is partly because, despite a number of studies on the subject, cases of IMLN metastasis are relatively rare, and there are few cases of curative resection because of metastasis to other organs. A retrospective study involving a large number of patients was conducted. METHODS The subjects were 2,743 patients registered in the national registry of the Japanese Society for Cancer of the Colon and Rectum. The data were analyzed for (1) prognostic factors for IMLN metastasis, and (2) outcomes in R0 cases with IMLN metastasis. RESULTS In the control group, 67 patients (2.7 %) were considered positive for IMLN metastasis. The outcomes in the 35 R0 cases with IMLN metastasis were 50.8 % for 5-year relapse-free survival (RFS) and 61.9 % for 5-year overall survival (OS), which were each better than for R1+R2 cases (5-year RFS 16.1 %, p = 0.0001; 5-year OS 26.7 %, p = 0.0002). The outcomes for R0 cases (total metastatic lymph nodes ≥7) with IMLN metastasis (5-year RFS 53.9 %, 5-year OS 68.8 %) did not differ significantly from those for IMLN(-) cases (5-year RFS 54.6 %, 5-year OS 57.1 %) (RFS: p = 0.9515, OS: p = 0.4621). CONCLUSIONS It was confirmed that cases of IMLN metastasis in low rectal cancer tend to have a large total number of metastatic lymph nodes, but if curative resection can be performed, a good prognosis can be expected. These results demonstrate the value of radical Japanese D3 lymph node dissection in low rectal cancer with IMLN metastasis.

Abstract
Purpose Lymph node metastasis is an important factor for predicting the prognosis of colorectal cancer patients. However, approximately 60% of patients do not receive adequate lymph node evaluation (less than 12 lymph nodes). In this study, we identified a more effective tool for predicting the prognosis of patients who received inadequate lymph node evaluation. Materials and Methods The number of metastatic lymph nodes, total number of lymph nodes examined, number of negative metastatic lymph nodes (NL), lymph node ratio (LR), and the number of apical lymph nodes (APL) were examined, and the prognostic impact of these parameters was examined in patients with colorectal cancer who underwent surgery from January 2004 to December 2011. In total, 806 people were analyzed retrospectively. Results In comparison of different lymph node analysis methods for rectal cancer patients who did not receive adequate lymph node dissection, the LR showed a significant difference in overall survival (OS) and the APL predicted a significant difference in disease-free survival (DFS). In the case of colon cancer patients who did not receive adequate lymph node dissection, LR predicted a significant difference in DFS and OS, and the APL predicted a significant difference in DFS. Conclusion If patients did not receive adequate lymph node evaluation, the LR and NL were useful parameters to complement N stage for predicting OS in colon cancer, whereas LR was complementary for rectal cancer. The APL could be used for prediction of DFS in all patients.

Abstract
PURPOSE The aim of this study is to establish a prediction scoring system for inferior mesenteric artery (IMA) lymph node metastasis and to assess the prognostic impact of dissection of positive IMA node on patients with stage III rectal cancer. METHODS A retrospective study was performed in 264 patients with stage III rectal cancer undergoing curative surgery. Clinicopathological, survival, and recurrence data were compared between 29 patients with positive IMA nodes and 235 patients with negative IMA nodes. Clinicopathological data which were found to be significantly associated with IMA nodal status were incorporated into a scoring system. RESULTS In the training samples, tumor differentiation and preoperative serum CEA were significant predictors of IMA node metastasis in multivariate analysis, which were incorporated into a scoring system. Using receiver operating characteristic curve analysis, we determined a cutoff value of 46.5 for scores, at which the system's sensitivity was 86 % and specificity 61 %. When applied to testing sample, the sensitivity was 80 % and specificity 60 %. Survival analysis showed that 5-year disease-free survival rate (5-DFS) and 5-year overall survival (5-OS) in the positive IMA node group (24.4 and 27.6 %, respectively) were significantly lower than in the negative IMA node group (61.8 and 71.3 %, respectively) (P < 0.001). Furthermore, multivariate analysis indicated that IMA lymph node metastasis was an unfavorable independent prognostic factor for 5-DFS and 5-OS. CONCLUSIONS IMA lymph node metastasis is an independent poor prognostic factor for stage III rectal cancer. The prediction scoring system for IMA node metastasis would be beneficial in determining the appropriate level of IMA ligation.
