Abstract Background: It is difficult to predict lymph node metastasis in patients with early lung cancer. Pure ground glass opacity (GGO) on computed tomography indicates an early-stage adenocarcinoma that can be removed by limited resection or lobectomy without the need for mediastinal lymph node dissection or sampling, and lung adenocarcinoma with GGO therefore has a good prognosis. We examined the incidence and risk factors of lymph node metastasis in patients with clinical stage IA lung adenocarcinoma. Methods: We retrospectively analyzed clinical data for 327 patients with stage IA peripheral lung cancer treated in our hospital from March 2014 to December 2018. The patients were divided into four groups according to computed tomography signs. Lobectomy and systematic lymph node dissection were performed in all patients. Correlations between lymph node metastasis and clinical pathological factors were analyzed by logistic regression.Results: Among the 327 patients, 26 (7.95%) had lymph node metastasis. No patients with pure GGO or GGO-dominant types had lymph node metastasis. Logistic regression identified tumor diameter, solid content, plasma carcinoembryonic antigen (CEA) level, pathological type, lymphovascular invasion, and pleural invasion as factors related to the presence of lymph node metastasis. Conclusions: Tumor diameter, solid component ratio, plasma CEA level, pathological type, vascular tumor thrombus, and pleural invasion are possible independent risk factors for lymph node metastasis in patients with stage IA lung adenocarcinoma. In contrast, lymph node metastasis is rare in patients with pure GGO or GGO-dominant lung adenocarcinoma.

Background: Previous researches had not proposed any prediction models for occult lymph node metastasis (OLNM). Considering the occurrence of OLNM and the importance of OLNM management, we aimed to develop a nomogram to predict OLNM of patients with lung adenocarcinoma ≤2 cm. Methods: Characteristics of patients with lung adenocarcinoma of ≤2 cm diameter at the Peking Union Medical College Hospital were retrospectively reviewed. Univariate and multivariate logistic regressions were performed. A nomogram model was developed. The concordance index (C-index) and calibration and decision curves were used to evaluate the predictive ability. Results: A total of 473 patients were enrolled, with an OLNM incidence of 7.4%. Four factors were selected as risk factors. The model had a C-index of 0.932. Calibration and decision curves were determined. Conclusion: Patients with pure ground-glass opacity (pGGO) or noninvasive adenocarcinoma have significantly lower risk of OLNM. SUVmax, CEA, micropapillary and solid component were identified as independent risk factors. The nomogram model was effective in predicting OLNM preoperatively.

Background: Lobectomy plus lymph node dissection is the standard treatment of early-stage lung cancer, but the low lymph node metastasis rate with ground-glass opacity (GGO) makes surgeons not perform lymphadenectomy. This study aimed to re-evaluate the lymph node metastasis rate of GGO to help make a clinical judgment. Methods: We performed this retrospective study to enroll patients who received lung cancer surgery from 2011 to 2016. Patient characteristics collected included tumor size, solid part size and lymph node metastasis rate. These patients were categorized into pure GGO and part solid GGO groups to undergo analysis. Results: Lymph node metastasis rates were 0%, 3.8% and 6.9% in order of the pure GGO group, the GGO predominant group and the solid predominant group. In the lobectomy patients, the solid predominant group still showed to have the highest lymph node metastasis rate and recurrence rate (8.3% and 10.1%). Conclusion: It is unnecessary to perform lymphadenectomy for patients with pure GGO in view of the 0% lymph node metastasis rate. The higher lymph node metastasis rate in the patients with the solid predominant group, 6.9%, suggested that surgeons should choose a rational lymphadenectomy method according to their GGO property and clinical judgment.

Abstract Background A nomogram was developed to predict lymph node metastasis (LNM) for patients with early-stage esophageal squamous cell carcinoma (ESCC). Methods We used the clinical data of ESCC patients with pathological T1 stage disease who underwent surgery from January 2011 to June 2018 to develop a nomogram model. Multivariable logistic regression was used to confirm the risk factors for variable selection. The risk of LNM was stratified based on the nomogram model. The nomogram was validated by an independent cohort which included early ESCC patients underwent esophagectomy between July 2018 and December 2019. Results Of the 223 patients, 36 (16.1%) patients had LNM. The following three variables were confirmed as LNM risk factors and were included in the nomogram model: tumor differentiation (odds ratio [OR] = 3.776, 95% confidence interval [CI] 1.515–9.360, p = 0.004), depth of tumor invasion (OR = 3.124, 95% CI 1.146–8.511, p = 0.026), and tumor size (OR = 2.420, 95% CI 1.070–5.473, p = 0.034). The C-index was 0.810 (95% CI 0.742–0.895) in the derivation cohort (223 patients) and 0.830 (95% CI 0.763–0.902) in the validation cohort (80 patients). Conclusions A validated nomogram can predict the risk of LNM via risk stratification. It could be used to assist in the decision-making process to determine which patients should undergo esophagectomy and for which patients with a low risk of LNM, curative endoscopic resection would be sufficient.

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.

e21084 Background: This study aimed to investigate the efficacy of the Deauville criteria, a 5-point visual scale criteria to assess the maximum standardized uptake value (SUVmax) of [18F]-fluoro-2-deoxy-D-glucose (FDG) on positron emission tomography (PET)/computed tomography (CT), in predicting lymph node metastasis and other pathological invasive characteristics of early-stage lung adenocarcinoma. Methods: In this retrospective study including 453 patients undergoing lobectomy or segmentectomy with lymph node dissection for clinical N0 lung adenocarcinoma with a whole size ≤ 3 cm between April 2011 and March 2019, the FDG-PET/CT scans were evaluated using the Deauville criteria to analyze the relationship of Deauville score with the clinicopathological characteristics and prognosis.The scoring method was as follows: Deauville score of 1, no FDG uptake by the primary tumor (same as background); Deauville score of 2, tumor FDG uptake that is the same as or weaker than that of mediastinum; Deauville score of 3, tumor FDG uptake that is stronger than that of mediastinum but same as or weaker than that of liver; Deauville score of 4, tumor FDG uptake that is moderately higher than that of liver; Deauville score of 5, tumor FDG uptake that is markedly stronger than that of liver. Results: The lymph node metastases were present in 0 (0%), 2 (1.1%), 6 (9.5%), 6 (15.8%), and 13 (15.7%) patients with Deauville scores of 1, 2, 3, 4 and 5, respectively. The pathological invasive characteristics (lymphatic, vascular, or visceral pleural invasion) were detected in 2 (2.4%), 17 (9.9%), 18 (28.6%), 23 (60.5%), and 54 (65.1%) patients, respectively. Similar results were found when the study cohort was analyzed according to the institutions where the FDG-PET/CT scans were performed. The 3-year recurrence-free survival was longer in the patients with a Deauville score of 1–2 (97.2%) than those with a Deauville score of 3 (86.2%, p < 0.001) or 4–5 (80.7%, p < 0.001). Conclusions: The 5-point-scale evaluation of the SUVmax on FDG-PET/CT using the Deauville score was useful in predicting not only lymph node metastasis but also other malignancy characteristics of early-stage lung adenocarcinoma.
