e18005 Background: Evaluation the distribution of nodal metastases in the stage IB1 cervical cancer and the risk factors associated with pelvic lymph node metastasis (LNM) at each anatomic location. Methods: 728 patients with stage IB1 cervical cancer who underwent radical hysterectomies and systemic pelvic lymphadenectomies from January 2008 to December 2017 were retrospectively studied. All removed pelvic lymph nodes were pathologically examined, and the risk factors for LNM at the obturator, internal iliac, external iliac, and common iliac regions were evaluated by univariate and multivariate logistic regression analyses. Results: 20,134 lymph nodes were analysed with the average number of 27.80 (± SD 9.43) lymph nodes per patient. Nodal metastases were present in 266 (14.6%) patients. The obturator was the most common site for nodal metastasis (42.5%) followed by the internal iliac nodes (20.3%) and the external iliac nodes (19.9%), while the common iliac (9.8%) and parametrial (7.5%) nodes were the least likely to be involved. Tumor size more than 2 cm, histologically proven lymphovascular space involvement (LVSI) and parametrial invasion correlated independently significantly with the higher risk of the lymphatic metastasis. Obesity (BMI≥25) was independently significantly negatively correlated with the risk of lymphatic metastases. All the positive common iliac nodes were found in patients with tumors greater than 2 cm. The multivariate analysis showed that tumor size greater than 3 cm was associated with a 16.6-fold increase in the risk for common iliac LNM. Interestingly, tumor size was not an independent risk factor for pelvic LNM in the lower regions, i.e., the obturator, internal iliac and external iliac areas, where LVSI was the most significant predictor for LNM. In addition, parametrial invasion was related to external and internal iliac LNM; deep stromal invasion and age less than 50 years were associated with obturator LNM. Conclusions: The incidence of lymph node metastasis in patients with stage IB1 cervical cancer is low but prognostically relevant. The data offer the opportunity for tailored individual treatment in selected patients with small tumors and obesity.

ObjectivesThe aims of this study were to predict pelvic lymph node metastasis in uterine cervical cancer before surgery and to evaluate the potential efficacy of omitting pelvic lymphadenectomy.Materials and MethodsA total of 163 patients with invasive uterine cervical cancer in FIGO stage IA2 to IIB, all of whom underwent primary radical hysterectomy with pelvic lymphadenectomy, participated in this study.ResultsThe incidences of pelvic lymph node metastasis in stage IA2, stage IB1, stage IB2, stage IIA, and stage IIB cervical cancer were 0% (0/12), 17% (13/76), 22% (6/27), 33% (8/24), and 63% (15/24), respectively. A significant difference was observed in overall survival with nodal metastasis status (P< 0.0001). Univariate analysis revealed that parametrial invasion (P< 0.0001), tumor markers (P= 0.0006), tumor size greater than 2 cm (P< 0.0001), tumor size less than 3 cm (P= 0.0009), and tumor size greater than 4 cm (P= 0.0024) were correlated with pelvic lymph node metastasis. However, multivariate analysis revealed that parametrial invasion (P= 0.01; odds ratio, 3.37; 95% confidence interval, 1.31–9.0) and tumor size greater than 2 cm (P= 0.005; odds ratio, 4.93; 95% confidence interval, 1.54–22.01) were independently associated with nodal metastasis.ConclusionsPelvic lymphadenectomy may be avoided in patients with negative parametrial invasion and a tumor size less than 2 cm, thereby minimizing postoperative complications.

Abstract Objective To summarize the lymph node metastasis (LNM) rate of patients with stage ⅠA-ⅡA cervical cancer, and further analyze its distribution characteristics and related risk factors. Methods According to FIGO 2009, the clinical data of 975 patients with stage ⅠA-ⅡA cervical cancer treated in our hospital from January 2010 to December 2018 were retrospectively analyzed. The incidence and distribution of LNM were analyzed, and the influencing factors of cervical cancer LNM were analyzed by univariate and multivariate Logistic regression. Results In this study, the LNM rate was 14.8%(144/975), and a total of 20288 lymph nodes were removed, among which 359 lymph nodes had metastasis. According to the statistics of the number and frequency of metastatic lymph nodes in different regions, the metastatic rate was the highest in the parauterine/obturator regions. Univariate analysis showed that pregnancy > 3 times, tumor size > 4cm, gross type, FIGO stage, pathological type, positive lymphovascular space invasion (LVSI), deep cervical stromal invasion (outer 1/2 invasion), parametrial involvement and uterine corpus invasion (UCI) were all correlated with LNM (P <0.05). Multivariate analysis showed tumor lesion >4cm (OR=2.253,95%CI:1.486-3.416,P<0.001), positive LVSI (OR=5.353,95%CI: 3.303-8.676, P <0.001), deep cervical stromal invasion (OR=3.461, 95%CI: 2.106-5.688, P<0.001)and deep UCI (myometrial invasion≥50%) (OR=3.529, 95%CI: 1.321-9.427, P=0.012)were independent risk factors for LNM. Conclusion C ervical cancer patients are more likely to have LNM if the tumor size > 4cm, positive LVSI, deep cervical stromal invasion and deep UCI. In clinical treatment, attention should be paid to the evaluation of LNM.

Abstract Background It remains controversial whether splenic hilum lymph nodes (SHLNs) should be excised in radical gastrectomy with D2 lymph node dissection. In this study, we evaluated the role of clinicopathological features in patients with gastric cancer in predicting splenic hilum lymph nodes metastasis.Methods We searched the Medline, Embase, PubMed and Web of Science databases from inception to May 2020 and consulted related references. 15 articles with a total of 4377 patients were included finally. The odds ratios (ORs) of each risk factor and the corresponding 95% confidence interval (CI) were determined using Revman 5.3 software. Results Meta-analysis showed that tumor size greater than 5 cm (p < 0.01), tumor localization in the greater curvature (p < 0.01), diffuse type (Lauren’s type) (p < 0.01), Borrman type 3–4 (p < 0.01), poor differentiation and undifferentiation (p < 0.01), depth of invasion T3–T4 (p < 0.01), number of lymph node metastases N2–N3 (p < 0.01), distance metastasis M1 (p < 0.01), TNM stage 3–4 (p < 0.01), vascular invasion (p = 0.01), and lymphatic invasion (p < 0.01) were risk factors of SHLNs metastasis. Moreover, No. 1-, 2-, 3-, 4sa-, 4sb-, 4d-, 6-, 7-, 9-, 11-, and 16-positive lymph node metastasis are strongly associated with splenic hilum lymph nodes metastasis.Conclusions Tumor size, tumor location, Lauren’s type, Borrman type, degree of differentiation, T stage, N stage, M stage, TNM stage, vascular invasion, lymphatic infiltration, and other positive lymph nodes metastasis were risk factors for SHLNs.

Abstract Background Systematic pelvic lymphadenectomy or whole pelvic irradiation is recommended for the patients with stage IB1 cervical cancer. However, the precise pattern of lymphatic tumor spread in cervical cancer is unknown. In the present study we evaluated the distribution of nodal metastases in stage IB1 cervical cancer to explore the possibilities for tailoring cancer treatment. Methods A total of 289 patients with cervical cancer of stage IB1, according to FIGO 2009, were retrospectively analyzed. All patients underwent laparoscopic radical hysterectomy (Querleu and Morrow type C2) and systematic pelvic lymphadenectomy with or without para-aortic lymphadenectomy (level 2 or level 3 according to Querleu and Morrow) from October 2014 to December 2017. Lymph nodes removed from 7 well-defined anatomical locations as well as other tissues were examined histopathologically, and typed, graded, and staged according to the WHO/IARC classification. Results Totally 8314 lymph nodes were analyzed with the average number of 31.88 ± 10.34 (Mean ± SD) lymph nodes per patient. Nodal metastases were present in 44 patients (15.22%). The incidence of lymphatic spread to different anatomic sites ranged from 0% (presacral) to 30.92% (obturator nodes). Tumor size above 2 cm, histologically proven lymphovascular space involvement (LVSI) and parametrial invasion were shown to be significantly correlated with the higher risk of lymphatic metastasis, while obesity (BMI ≥ 25) was independently negatively associated with lymphatic metastases. Conclusions The incidence of lymph node metastasis in patients with stage IB1 cervical cancer is low but prognostically relevant. Individual treatment could be considered for the selected low-risk patients who have smaller tumors and obesity and lack of the parametrial invasion or LVSI.
