Predictive factors of lymph node metastasis in intramucosal poorly differentiated early gastric cancer and their impact on the laparoscopic surgery

Objective

The aim of this study was to identify clinicopathological factors predictive of lymph node metastasis (LNM) in intramucosal poorly differentiated early gastric cancer (EGC), and further to expand the possibility of using laparoscopic surgery for the treatment of intramucosal poorly differentiated EGC.

Methods

Data from 65 patients with intramucosal poorly differentiated EGC and surgically treated were collected, and the association between the clinicopathological factors and the presence of LNM was retrospectively analyzed by univariate and multivariate logistic regression analyses.

Results

Univariate analysis showed that number of tumors, tumor size and lymphatic vessel involvement (LVI) were the significant and independent risk factors for LNM (all P < 0.05). The LNM rates were 5.0%, 18.2% and 66.7%, respectively. There was no LNM in 31 patients without the three risk clinicopathological factors

Conclusion

The number of tumors, tumor size, and LVI are independently associated with the presence of LNM in intramucosal poorly differentiated EGC. Thus, these three risk factors may be used to set as a simple criterion to expand the possibility of using laparoscopic surgery for the treatment of intramucosal poorly differentiated EGC.

A case of small undifferentiated intramucosal gastric cancer with lymph node metastasis

Early gastric cancer (EGC) has a favorable prognosis after surgical gastrectomy. For intramucosal EGC with little risk of lymph node metastasis, endoscopic mucosal resection (EMR) is an accepted treatment method. Herein we document a noteworthy case of small undifferentiated gastric cancer with nodal metastasis. A 60-year-old Japanese woman underwent gastrectomy with D2 lymph node dissection for the treatment of EGC in the lower gastric body. Histological examination revealed that signet-ring cell carcinoma was located in approximately one-third of the superficial portion of the mucosal layer, with a tumor size of 13 mm. No lymphatic invasion, venous invasion, or fibrosis was observed in the submucosal layer. This case had nodal metastasis and was finally diagnosed as stage IB (T1N1M0) according to the Japanese Classification of Gastric Carcinoma (JCGC). The patient is alive without recurrence 6 years after treatment.     

Risk factors for paraaortic lymph node metastasis in endometrial cancer

Objective

The purpose of this study was to determine the risk factors for paraaortic lymph node (LN) metastasis in endometrial cancer (EC) patients who underwent comprehensive surgical staging.

Methods

A total of 641 women with EC (endometrioid, non-endometrioid, or mixed histology) who underwent comprehensive surgical staging including pelvic and paraaortic LN dissection between 2008 and 2016 were included in this retrospective study. Patient data were analyzed with respect to paraaortic LN involvement, and predictive factors for paraaortic LN metastasis were investigated.

Results

Lymph node metastasis was detected in 90 (14%) patients, isolated pelvic LN metastasis in 28 (4.3%), isolated paraaortic LN metastasis in 15 (2.3%), and both pelvic and paraaortic LN metastasis in 47 (7.3%) women, respectively. Univariate analysis showed that the risk of paraaortic LN metastasis significantly increased in patients with non-endometrioid histology, age greater than 60 years, grade 3 tumor, deep myometrial invasion, lymphovascular space invasion (LVSI), primary tumor diameter (≥2 cm), cervical stromal invasion, adnexal involvement, serosal invasion, pelvic LN involvement, two or more positive pelvic LNs, and positive peritoneal cytology (p < 0.05). At the end of multivariate analysis, the presence of LVSI [odds ratio (OR), 4.8; 95% confidence interval (CI), 1.25–18.2; p = 0.022] and pelvic LN metastasis (OR, 18.8; 95% CI, 5.7–61.6; p < 0.001) remained as independent risk factors for paraaortic LN involvement in women with EC.

Conclusion

The presence of LVSI and pelvic LN involvement appear to be independent risk factors for paraaortic LN metastasis in patients with EC. LVSI may be considered as a routine pathological parameter during frozen section analysis in women with EC undergoing surgery.

Risk factors for lymph node metastasis in early gastric cancer without lymphatic invasion after endoscopic submucosal dissection

BackgroundLymphatic invasion (LI) is a potent risk factor for lymph node metastasis (LNM) in early gastric cancer (EGC) after endoscopic submucosal dissection (ESD). However, there are also other risk factors for LNM. Hence, to identify the need for additional surgery in some case of EGC without LI, the present study aimed to identify the risk factors for LNM in patients with EGC without LI.MethodsData from 2284 patients diagnosed with EGC who underwent curative surgery at National Cancer Center in Korea from January 2012 to May 2019 were collected. The clinicopathological characteristics of patients with EGC without LI were compared on the basis of LNM status.ResultsThere were 339 (17.1%) and 1648 (82.9%) patients with and without LI respectively. Among these patients with and without LI, 118 (34.8%) and 91 (5.5%) patients presented with LNM, respectively. In patients with EGC without LI, tumor size larger than 3 cm (OR = 2.12, 95% CI = 1.22–3.68; p = 0.007), submucosal invasion (OR = 4.14, 95% CI = 2.57–6.65; p < 0.001), and undifferentiated histologic type (OR = 2.33, 95% CI = 1.45–3.76; p < 0.001) were significant risk factors for LNM. Rates of LNM in patients meeting absolute, expanded, and beyond expanded criteria without LI were 0%, 1.5% (OR = 3.27, 95% CI = 0.18–59.41; p = 0.423), and 7.3% respectively. When the expanded criteria were divided into four subtypes patients with EGC, without LI within each subtype did not show significant risk of incidence of LNM compared to the absolute criteria.ConclusionsThe current expanded criteria for endoscopic resection (ER) are tolerable in cases without LI, even though minimal risk LNM exists. Therefore, additional surgery may not be needed for patients meeting expanded criteria for ER.
