Abstract
BACKGROUND Stage III non-small cell lung cancer is a heterogeneous disease. Several international guidelines recommend neoadjuvant treatment before surgery; however, upfront surgery is the preferred approach for technically resectable non-small cell lung cancer in East Asia. The aim of this retrospective study was to evaluate the long-term outcomes of curative-intent upfront surgery in stage IIIA/B non-small cell lung cancer. METHODS Patients who underwent curative-intent upfront surgery with stage cIIIA/B non-small cell lung cancer were identified. The clinical and pathological variables and survival outcomes were evaluated. RESULTS Overall, 664 patients were identified, of whom 320 (48.8%) had N2 disease, 66.7% were males, 49.4% had a smoking history, and 61.2% had lung adenocarcinoma. Lobectomy was the most performed surgical procedure (84.9%). A total of 40 patients (6.02%) had positive margins (R1/R2). The grade III adverse event rate was 2.0% (13 of 664). The median follow-up was 30.6 (range 1.9-97.7) months. At follow-up, the mortality rate was 13.3% (88 of 664) and 37.2% of patients (247 of 664) had recurrence. Lung (101 of 247 (40.9%)) and brain (53 of 247 (21.5%)) were the most common sites of recurrence. The median overall survival was 60.0 (95% c.i. 51.5 to 67.6) months, with overall survival probability at 1, 2, 3, and 5 years being 89.6%, 77.8%, 67.2%, and 49.0% respectively. The R0 cohort showed an improved median overall survival compared with the R1/R2 cohort (67.4 versus 26.5 months respectively; P = greater than 0.001). The multivariable analysis revealed that age greater than or equal to 65 years (HR 1.51, 95% c.i. 1.08 to 2.12; reference = age less than 65 years), tumour size (greater than or equal to 5 cm (HR 2.13, 95% c.i. 1.41 to 3.21) and greater than or equal to 3 cm but less than 5 cm (HR 1.15, 95% c.i. 0.78 to 1.71); reference = less than 3 cm), and adjuvant treatment (chemotherapy (HR 0.69, 95% c.i. 0.49 to 0.96) and targeted therapy (HR 0.30, 95% c.i. 0.12 to 0.76); reference = none) significantly predicted overall survival. CONCLUSION Upfront surgery is an option for the management of stage IIIA/B non-small cell lung cancer.

Abstract
BACKGROUND Neoadjuvant chemotherapy (NACT) becomes the first-line option for advanced tumors, while patients who are not sensitive to it may not benefit. Therefore, it is important to screen patients suitable for NACT. METHODS Single-cell data of lung adenocarcinoma (LUAD) and esophageal squamous carcinoma (ESCC) before and after cisplatin-containing (CDDP) NACT and cisplatin IC50 data of tumor cell lines were analyzed to establish a CDDP neoadjuvant chemotherapy score (NCS). Differential analysis, GO, KEGG, GSVA and logistic regression models were performed by R. Survival analysis were applied to public databases. siRNA knockdown in A549, PC9, TE1 cell lines, qRT-PCR, western-blot, cck8 and EdU experiments were used for further verification in vitro. RESULTS 485 genes were expressed differentially in tumor cells before and after neoadjuvant treatment for LUAD and ESCC. After combining the CDDP-associated genes, 12 genes, CAV2, PHLDA1, DUSP23, VDAC3, DSG2, SPINT2, SPATS2L, IGFBP3, CD9, ALCAM, PRSS23, PERP, were obtained and formed the NCS score. The higher the score, the more sensitive the patients were to CDDP-NACT. The NCS divided LUAD and ESCC into two groups. Based on differentially expressed genes, a model was constructed to predict the high and low NCS. CAV2, PHLDA1, ALCAM, CD9, IGBP3 and VDAC3 were significantly associated with prognosis. Finally, we demonstrated that the knockdown of CAV2, PHLDA1 and VDAC3 in A549, PC9 and TE1 significantly increased the sensitivity to cisplatin. CONCLUSIONS NCS scores and related predictive models for CDDP-NACT were developed and validated to assist in selecting patients who might benefit from it.

Abstract
OBJECTIVES Optimal treatment of stage IIIA (N2) non-small-cell lung cancer (NSCLC) is controversial. Guidelines advise induction therapy before surgical resection. A proportion of patients with cN0 NSCLC are postoperatively upstaged due to unsuspected N2 disease. Survival of unsuspected N2 NSCLC treated with surgery varies and technical feasibility of video-assisted thoracic surgery (VATS) is unknown. The purpose of this study was to assess prevalence and survival of unsuspected N2 NSCLC treated with thoracotomy or VATS. METHODS A systematic review and meta-analysis was performed of all available literatures through Pubmed, Cochrane, EMBASE, Web of Science, Trials registries and System for Information on Grey Literature (SIGLE) from 2000 to 2019. Outcomes of interest were prevalence, overall survival (OS) and disease-free survival of unsuspected N2 NSCLC. Secondary outcomes were number of harvested lymph nodes, postoperative complications and survival of unsuspected N2 NSCLC treated with VATS. RESULTS Seventeen studies with patients with clinical stage N0-1 and unsuspected pN2 NSCLC were included. Prevalence of unsuspected pN2 was 8.6%. Three- and 5-year OS was 58% [95% confidence interval (CI) 37-78%) (N = 4337] and 35% (95% CI 28-43%) (N = 4337). Three- and 5-y ear disease-free survival was 48% (95% CI 30-66%) (N = 109) and 35% (95% CI 24-46%) (N = 517). VATS resulted in a low complication rate with similar 5-year OS as thoracotomy. CONCLUSIONS In patients with cN0-1 NSCLC, a minority has unsuspected pN2 NSCLC. Even for these patients, 5-year OS and disease-free survival are reasonable. VATS with adequate lymph node dissection is the treatment of choice when in experienced hands. Adjuvant therapy should be provided in absence of relevant comorbidity.

Abstract
OBJECTIVES Pathological N2 (pN2) involvement has a negative impact on prognosis in patients operated on due to non-small-cell lung cancer (NSCLC). pN2 disease may cause skip (pN0N2) or non-skip (pN1N2) metastases with pathological N1 (pN1) involvement. The effect of pN2 subgroups on prognosis is still controversial. We analysed the effect of pN1 disease and single-station pN2 disease subgroups on survival outcomes. METHODS The medical records of patients who underwent anatomical lung resection due to NSCLC at a single centre between January 2007 and January 2017 were prospectively collected and retrospectively analysed. Operative mortality, sublobar resection, Stage IV disease, incomplete resection and carcinoid tumour were considered exclusion criteria. After histopathological examination, the prognosis of patients with pN1, pN0N2 and pN1N2 was compared statistically. Univariable and multivariable analyses were made to define independent risk factors for overall survival rates. RESULTS The mean follow-up time for 358 patients with 228 pN1 disease (63.7%), 59 pN0N2 disease (16.5%) and 71 pN1N2 disease (19.8%) was 40.4 ± 30.4 months. Median and 5-year overall survival rates for pN1, pN0N2 and pN1N2 diseases were 73.6 months [95% confidence interval (CI) 55.5-91.7] and 54.1%, 60.3 months (95% CI 26.8-93.8) and 51.2%, 20.8 months (95% CI 16.1-25.5) and 21.5%, respectively. The survival CIs of pN1 and pN0N2 diseases were similar, and the survival rates of these 2 groups were significantly better than those with pN1N2 (P < 0.001, P = 0.001, respectively). In multivariable analysis, patients over the age of 60 [hazard ratio (HR) 2.13, P < 0.001], patients not receiving adjuvant therapy (HR 1.52, P = 0.01) and patients with pN1N2 disease (HR 2.91, P < 0.001) had a poor prognosis. CONCLUSIONS Advanced age, not receiving adjuvant therapy and having pN1N2 disease are negative prognostic factors in patients with nodal involvement who underwent curative resection due to NSCLC. The overall survival and recurrence-free survival rates of pN1 disease and single-station pN0N2 disease are similar, and they have significantly better survival rates than pN1N2 disease. Based on these results, surgical treatment may be considered an appropriate choice in patients with histopathologically diagnosed single-station skip-N2 disease.

Abstract
Background Thymic neuroendocrine tumors (TNT), in the anterior mediastinum, are extremely rare diseases which have significantly poor prognoses. Studies have rarely provided conclusive evidence of the prognostic factors of TNT. Standard therapies have been controversial. Methods TNT patients (n=173) were enrolled from Surveillance, Epidemiology and End Results database (SEER). Univariate and multivariate analyses were utilized to evaluate predictive factors of prognoses. Logistic regression analysis was used to assess the plausible correlation between histological grade, and cancer invasion. Stratification analysis was used to evaluate the effectiveness of adjuvant therapies. Results According to our analysis, local Masaoka stage, surgery, radiotherapy, and non-chemotherapy predicted better overall survival (OS) (P<0.05, for all) in 173 TNT patients. We found that the higher the histological grade of the tumor, the greater the rate of metastasis (P<0.05). The focus was on 125 surgically treated patients, who were females with poor prognostic factors of OS, upgraded histological grade, and advanced Masaoka stage (P<0.01, for all). The effectiveness of radiotherapy treatments had discrepancies at different clinical stages. In the local stage, radiotherapy caused significantly worse OS (P=0.011), while in the advanced stage, patients demonstrated significantly better OS with this treatment (P=0.028). Chemotherapy caused worse OS, primarily, in females (P=0.028). Conclusions Surgery, Masaoka stage, and adjuvant treatments were prognostic factors. With surgically treated TNT, gender, histological grade, and Masaoka stage predicted significantly worse OS. Chemotherapy decreased female patients' OS. Radiotherapy significantly promoted advanced and local advanced patients' OS; however, it decreased local stage patients' OS. Predicted TNT invasiveness significantly correlated with histological grade.
