Abstract Background and study aims Endoscopic treatment is indicated for superficial Barrett’s adenocarcinoma (BA) with a negligible risk of lymph node metastasis (LNM). However, risk factors associated with LNM in superficial BA are still not well characterized. The aim of the current study was to clarify risk factors for LNM of superficial BA. Patients and methods A retrospective study was conducted in 87 consecutive patients with BA that was resected at National Cancer Center Hospital, Tokyo, Japan between 1990 and 2013. We assessed tumor size, macroscopic type, histological type, tumor depth of invasion, lymphovascular invasion and tumor location to analyze factors associated with LNM. Tumor location was classified into following 2 groups according to Siewert classification: 1) BA of the esophagogastric junction (EGJ-BA) as those having their center within 1 cm proximal from the EGJ; and 2) Esophageal-BA as those having their center at 1 cm or more proximal to the EGJ. EGJ was defined as distal end of the palisade vessels. Results LNM was detected in 10 (11 %) patients. Univariable analysis revealed that tumor size, tumor depth of invasion, histological type of mixed differentiated and undifferentiated-type adenocarcinoma, lymphovascular invasion and tumor location of esophageal-BA were significantly associated with LNM. Multivariable analysis revealed that tumor location of esophageal-BA [odds ratio 7.8 (95 %CI: 1.3 – 48.1)] was a potential risk factor for LNM. Conclusions The current study demonstrated that tumor location is a potential risk factor for LNM in BA. Therefore, indications for endoscopic treatment of esophageal-BA and EGJ-BA could be different.

Abstract Background Estimating the risk of lymph node metastasis (LNM) is crucial for determining subsequent treatments following curative resection of early colorectal cancer (ECC). This multicenter study analyzed the risk factors of LNM and the effectiveness of postoperative chemotherapy in patients with ECC. Methods We retrospectively analyzed the data of 473 patients with ECC who underwent general surgery in five hospitals between January 2007 and October 2018. The correlations between LNM and sex, age, tumor size, tumor location, endoscopic morphology, pathology, depth of invasion and tumor budding (TB) were directly estimated based on postoperative pathological analysis. We also observed the overall survival (OS) and recurrence in ECC patients with and without LNM after matching according to baseline measures. Results In total, 473 ECC patients were observed, 288 patients were enrolled, and 17 patients had LNM (5.90%). The univariate analysis revealed that tumor size, pathology, and lymphovascular invasion were associated with LNM in ECC (P = 0.026, 0.000, and 0.000, respectively), and the multivariate logistic regression confirmed that tumor size, pathology, and lymphovascular invasion were risk factors for LNM (P = 0.021, 0.023, and 0.001, respectively). There were no significant differences in OS and recurrence between the ECC patients with and without LNM after matching based on baseline measures (P = 0.158 and 0.346, respectively), and no significant difference was observed between chemotherapy and no chemotherapy in ECC patients without LNM after surgery (P = 0.729 and 0.052). Conclusion Tumor size, pathology, and lymphovascular invasion are risk factors for predicting LNM in ECC patients. Adjuvant chemotherapy could improve OS and recurrence in patients with LNM but not always in ECC patients without LNM.

Abstract Background Esophagectomy and lymph node dissection is still the main treatment for esophageal cancer. Endoscopic mucosal resection and submucosal dissection are increasingly becoming a treatment of choice to preserve the integrity of the esophagus and decrease the surgical trauma in early esophageal cancer. However, lymph node metastasos (LNM) risk is still a debate focus for the decision of treatment selection. Our objective was to evaluate the prevalence, pattern and risk factors of LNM in early stage esophageal cancer to improve surgical treatment allocation. Methods We identified patients with pathological T1 stage esophageal cancer who underwent esophagectomy and lymph node dissection. The pattern of LNM was analyzed and the risk factors related to LNM were assessed by univariate and multivariable logistic regression analysis.The nomogram model was used to estimate the individual risk of lymph node metastasis. Results In 143 patients, LNM rates were: all patients 17.5%, T1a 8.0%, and T1b 22.5% for T1b. Depth of tumor infiltration (P < 0.05), tumor size (P < 0.01), tumor location (P < 0.05), and tumor differentiation (P < 0.01) were independent risk factors related to LNM. These four parameters allowed the compilation of a nomogram to estimate the individual risk of LNM. Fig. Nomogram to estimate the individual risk of LNM. Each characteristic of the included parameters scores a specific number of points (points per parameter). The summarized total points score indicates the probability of LNM. For a middle esophageal cancer with middle differentiated (G2), 3 cm tumor (> 2.5cm) that invades the submucosa (pT1b), the calculated total scores is 129.5 = 87.5 + 21 + 0 + 21, hence the corresponding LNM risk is 20%. Conclusion T1 esophageal cancer has a relatively high LNM rate, and the depth of tumor infiltration, tumor size, tumor location and tumor differentiation are correlated with LNM. Nomograms that include factors can be used to predict individual LNM risk. The LNM risk and extent must be considered comprehensively in decision-making of a better surgical treatment and lymph node dissection strategy.

Abstract   Recurrent laryngeal nerve lymph node metastasis (RLN LNM) is not rare in patients with esophageal cancer. We aimed to explore the risk factors for RLN LNM and to develop a nomogram predicting the likelihood of RLN LNM in esophageal squamous cell carcinoma (ESCC) patients. Methods We retrospectively reviewed patients with ESCC who underwent esophagectomy as well as recurrent laryngeal nerve lymph node dissection between May 2015 and February 2019 at two different institutions. The patients were divided into negative and positive groups according to the presence of RLN LNM. Risk factors for RLN LNM were evaluated by univariate and multivariate analyses. A nomogram was constructed for presentation of the final model. Results A total of 390 patients with ESCC were included in this study. The differences in tumor location, tumor differentiation, T stage, tumor size and carcinoembryonic antigen (CEA) between the negative (N = 270) and positive groups (N = 120) RLN LNM were significant (P &lt; 0.05). Multivariate analysis indicated that the tumor location (OR = 0.520, 95% CI: 0.361–0.749, P &lt; 0.001), tumor differentiation (OR = 2.279, 95% CI: 1.586–3.276, P &lt; 0.001), T stage (OR = 1.436, 95% CI: 1.029–2.003, P = 0.033), tumor size (OR = 1.781, 95% CI: 1.021–3.106, P = 0.042) and CEA (OR = 1.206, 95% CI: 1.003–1.450, P = 0.046) were independent risk factors for RLN LNM. A nomogram with these variables had good predictive accuracy (c-index: 0.716). Conclusion Tumor location, tumor differentiation, T stage, tumor size and CEA may predict the risk of RLN LNM. We created a nomogram predicting the likelihood of RLN LNM in patients with ESCC.

19 Background: Peritoneal recurrence is often observed in gastric cancer patients without serosal invasion. It is difficult for pathologists to evaluate whether tumor cells penetrate serosa or not, because the subserosa layer is very thin. We evaluated the incidence and risk factors of peritoneal recurrence in serosa -negative gastric cancer patients to clarify the mechanism of peritoneal recurrence in these patients. Methods: A total of 1,745 gastric cancer patients underwent R0 resection from 2002 to 2009 were enrolled. The incidence of peritoneal recurrence according to tumor depth was analyzed. In serosa-nagative patients, the univariate and multivariate analysis were performed to identify the risk factors for peritoneal recurrence. Results: Peritoneal recurrence was observed in 64 (3.7 %) out of 1,745 patients. The incidence of peritoneal recurrence according to depth of tumor invasion was in 0 / 466 in T1a, 5 / 567 (0.88 %) in T1b, 4 / 187 (2.1 %) in T2, 31 / 360 (7.9 %) in T3, 20 / 108 (15.9 %) in T4a, and 4 / 12 (25 %) in T4b, respectively (p<0.001). As for the risk factor for peritoneal recurrence in T3 patients, histologically undifferentiated type, negative lymphatic invasion, scirrhous type, invasive infiltrating growth pattern were the significant factors identified by univariate analysis. Only the invasive infiltrating growth pattern (OR3.44 p0.038) was selected as significant independent risk factor for peritoneal recurrence by multivariate analysis. In T1b / T2 patients, massive lymph node metastasis (N3a, 3b), scirrhous type were the significant factor for peritoneal recurrence by univariate analysis. Only massive lymph node metastasis (OR25.1 p<0.001) was selected as the significant independent risk factor by multivariate analysis. Conclusions: The incidence of peritoneal recurrence increases in proportion to the tumor depth. Invasive infiltrating growth pattern was selected as an independent risk factor for peritoneal recurrence in T3 patients, while it was massive lymph node metastasis in T1b / T2 patients. The results suggest the possibility that microscopic serosal invasion in T3 tumor and lymphatic progression in T1b / T2 tumor may contribute to peritoneal recurrence in gastric cancer.

e17012 Background: To explore whether pathologically verified uterine corpus invasion (UCI) is a risk factor for patients with early-stage (IB1-IIA2) cervical carcinoma receiving radical surgery. Methods: A mathed-case comparison of early-stage cervical carcinoma patients with pathologically verified UCI to patients without UCI on a 1:1 ratio was conducted. High risk factors (lymph node metastasis, paremetrial invasion, vaginal margin invasion) and intermediate risk factors (lymphovascular space invasion (LVSI) and deep stromal invasion) were completely matched between UCI and non-UCI groups. Kaplan-Meier and Log-rank test were applied for univariate analysis, and COX proportional hazard regression models were used for multivariate analysis. Results: 1320 consecutive patients with cervical carcinoma received surgery in our centerfrom Jan. 1st2009 to Dec 31st2014. 79 (5.98%) cases with UCI were identified. Median follow-up time was 43 months. There were 22 cases with recurrence. In UCI group, the recurrence rate was 20.3% (16/79), and in non-UCI group the recurrence rate was 7.6% (6/79). On univariate analysis, SCC, neoadjuvant chemotherapy (NACT), lymph node metastasis, parametrial invasion, LVSI, deep stromal invasion, vaginal invasion and UCI were significantly associated with disease free survival (DFS). After multivariate analysis, UCI ( p= 0.02, RR3.832, 95% CI1.235-11.893)and lymph node metastasis ( p= 0.042, RR 2.890, 95% CI1.038-8.045) were still independent risk factors for deceased DFS. Conclusions: Pathologically verified uterine corpus invasion might be an independent risk factor for decreased DFS in patients with early-stage cervical carcinoma receiving radical surgery.

BackgroundLymph node metastasis (LNM) has a significant impact on the prognosis of patients with early gastric cancer (EGC). Our aim was to identify the independent risk factors for LNM and construct nomograms for male and female EGC patients, respectively.MethodsClinicopathological data of 1,742 EGC patients who underwent radical gastrectomy and lymphadenectomy in the First Affiliated Hospital, Second Affiliated Hospital, and Fourth Affiliated Hospital of Anhui Medical University between November 2011 and April 2021 were collected and analyzed retrospectively. Male and female patients from the First Affiliated Hospital of Anhui Medical University were assigned to training sets and then from the Second and Fourth Affiliated Hospitals of Anhui Medical University were enrolled in validation sets. Based on independent risk factors for LNM in male and female EGC patients from the training sets, the nomograms were established respectively, which was also verified by internal validation from the training sets and external validation from the validation sets.ResultsTumor size (odd ratio (OR): 1.386, p = 0.030), depth of invasion (OR: 0.306, p = 0.001), Lauren type (OR: 2.816, p = 0.000), lymphovascular invasion (LVI) (OR: 0.160, p = 0.000), and menopause (OR: 0.296, p = 0.009) were independent risk factors for female EGC patients. For male EGC patients, tumor size (OR: 1.298, p = 0.007), depth of invasion (OR: 0.257, p = 0.000), tumor location (OR: 0.659, p = 0.002), WHO type (OR: 1.419, p = 0.001), Lauren type (OR: 3.099, p = 0.000), and LVI (OR: 0.131, p = 0.000) were independent risk factors. Moreover, nomograms were established to predict the risk of LNM for female and male EGC patients, respectively. The area under the ROC curve of nomograms for female and male training sets were 87.7% (95% confidence interval (CI): 0.8397–0.914) and 94.8% (95% CI: 0.9273–0.9695), respectively. For the validation set, they were 92.4% (95% CI: 0.7979–1) and 93.4% (95% CI: 0.8928–0.9755), respectively. Additionally, the calibration curves showed good agreements between the bias-corrected prediction and the ideal reference line for both training sets and validation sets in female and male EGC patients.ConclusionsNomograms based on risk factors for LNM in male and female EGC patients may provide new insights into the selection of appropriate treatment methods.

Abstract Aim It is still controversial whether the addition of lateral pelvic lymph node (LPN) dissection (LPND) to total mesorectal excision (TME) can provide a survival benefit after neoadjuvant chemoradiotherapy (nCRT) in rectal cancer patients with pathological lateral lymph node metastasis (LPNM). Methods Patients with clinically suspected LPNM who underwent nCRT followed by TME + LPND were systematically reviewed and divided into the positive LPN group (n = 15) and the negative LPN group (n = 58). Baseline characteristics, clinicopathological data and survival outcomes were collected and analysed. Results Of the 73 patients undergoing TME + LPND after nCRT, the pathological LPNM rate was 20.5% (15/73). Multivariate analysis showed that a post-nCRT LPN short diameter ≥ 7 mm (OR 49.65; 95% CI 3.98–619.1; P = 0.002) and lymphatic invasion (OR 9.23; 95% CI 1.28–66.35; P = 0.027) were independent risk factors for pathological LPNM. The overall recurrence rate of patients with LPNM was significantly higher than that of patients without LPNM (60.0% vs 27.6%, P = 0.018). Multivariate regression analysis identified that LPNM was an independent risk factor not only for overall survival (OS) (HR 3.82; 95% CI 1.19–12.25; P = 0.024) but also for disease-free survival (DFS) (HR 2.33; 95% CI 1.02–5.14; P = 0.044). Moreover, N1-N2 stage was another independent risk factor for OS (HR 7.41; 95% CI 1.63–33.75; P = 0.010). Conclusions Post-nCRT LPN short diameter ≥ 7 mm and lymphatic invasion were risk factors for pathological LPNM after nCRT. Furthermore, patients with pathological LPNM still show an elevated overall recurrence rate and poor prognosis after TME + LPND. Strict patient selection and intensive perioperative chemotherapy are crucial factors to ensure the efficacy of LPND.
