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 The therapeutic strategies for clinical stage T1-3N2 (cT1-3N2) lung cancer are controversial. For operable tumors, treatment can vary by center, region, and continent. This study aimed to identify the optimal therapeutic method and type of surgical strategy for cT1-3N2 lung cancer. METHODS This retrospective evaluation analyzed the records of 17,954 patients with cT1-3N2 lung cancer treated in 2010 through 2015 from the SEER database. The effects of different therapeutic methods and types of surgical strategies on overall survival (OS) were assessed. Univariate and multivariate analyses were performed using a Cox proportional hazards model. RESULTS The 5-year OS rates were 27.7% for patients with T1N2 disease, 21.8% for those with T2N2 disease, and 19.9% for T3N2 disease. Neoadjuvant therapy plus operation (OP) plus adjuvant therapy, and OP plus adjuvant therapy, provided better 5-year OS rates than OP alone or concurrent chemoradiotherapy (34.1%, 37.7%, 29.3%, and 16.1%, respectively). In the T1N2, T2N2, and T3N2 groups, lobectomy provided better 5-year OS than pneumonectomy, sublobectomy, and no surgery. Both univariate and multivariate analyses showed that young age, female sex, well-differentiated histologic grade, adenocarcinoma cell type, neoadjuvant and adjuvant therapy, lobectomy, and T1 stage were statistically associated with better 5-year OS rates. CONCLUSIONS In cT1-3N2 lung cancer, multimodal treatments tended to provide better 5-year OS than OP alone or concurrent chemoradiotherapy. In addition, lobectomy was associated with better survival than other operative methods.

Abstract
Background Skip metastasis is a common lymph node metastatic pattern in non-small cell lung cancer (NSCLC). The relationship between skip metastasis and specific clinicopathologic factors and the prognostic value of skip metastasis are controversial. Methods A systematic search and analysis of skip metastasis in NSCLC was conducted in the databases of PubMed, EMBASE, and Web of Science up to Dec 2019. Summarized hazard ratio (HR), mean difference (MD), and odds ratio (OR) with associated 95% confidence intervals (CI) were evaluated to investigating the relationship between skip metastasis and overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS) and clinicopathological features in NSCLC. Results 29 studies with a total of 1,806 skip and 4,670 non-skip N2 patients were included. The upper lobe tumor showed a higher rate of skip metastasis compared with lower lobe one (RR =1.16, 95% CI: 1.00–1.34, P=0.044, I2=39.8%). The presence of skip metastasis correlated with superior overall survival (HR =0.74, 95% CI: 0.66–0.83, P<0.001, I2=48.2%) and DFS or RFS (HR =0.71, 95% CI: 0.61–0.84, P<0.001, I2=18.2%). Further subgroup analyses indicated similar results in articles that reported intrapulmonary lymph node dissection (HR =0.67, 95% CI: 0.57–0.77, P<0.001, I2=0). Conclusions The results indicate that the presence of skip metastasis is associated with a marked increase in survival of NSCLC patients compared to patients with non-skip N2 metastasis. These results suggest that skip metastasis might be a distinct subgroup for purposes of N staging of NSCLC patients, and intrapulmonary lymph node assessment is needed.

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
This study was conducted to evaluate the safety and effectiveness of localized lung resection combined with neoadjuvant chemotherapy in the treatment of stage I-II non-small cell lung cancer (NSCLC). A total of 88 patients, who were admitted to our hospital for first diagnosis and treatment, were selected. The patients were divided into control group (n=40 cases) and observation group (n=48 cases) according to the last digit of the admission number. The control group was treated with minimally invasive localized lung resection by thoracoscope. The observation group underwent the same procedure combined with two cycles of systemic neoadjuvant chemotherapy before the surgery was adopted in the observation group. The effects of both treatments were compared. The operation time, intraoperative blood loss and postoperative drainage volume of observation group were significantly lower than those of the control group (P<0.05). The surgical resection rate and margin negative rate of observation group were higher than those of control group, while the occurrence rate of complications was lower than that of control group; results were statistically significant (P<0.05). The serum neutrophil gelatinase associated lipocalin (lipocalin-2/NGAL), matrix metalloproteinase-9 (MMP-9) and carcinoembryonic antigen (CEA) levels of two groups after the treatment were lower than those before; however, levels in the observation group exhibited a distinct decrease. The difference has statistical significance (P<0.05). The follow-up time of two groups was 3-38 months and the median time was 20.5 months. The tumor survival period of observation group was not prolonged, however, the survival rate and quality rate of life were enhanced; the difference has statistical significance (P<0.05). Localized lung resection combined with neoadjuvant chemotherapy can effectively improve the surgical effect of stage I-II NSCLC, prolong the survival period, enhance the survival rate, decrease the occurrence rate of complications and reduce the tumor related factors lipocalin-2, MMP-9 and CEA levels.
