Background: To investigate the differences in survival between lobectomy and sub-lobar resection for elderly stage I non-small-cell lung cancer (NSCLC) patients using the Surveillance, Epidemiology, and End Results (SEER) registry.Method: The data of stage IA elderly NSCLC patients (≥ 70 years) with tumors less than or equal to 3 cm in diameter were extracted. Propensity-matched analysis was used. Lung cancer-specific survival (LCSS) was compared among the patients after lobectomy and sub-lobar resection. The proportional hazards model was applied to identify multiple prognostic factors.Results: A total of 3,504 patients met criteria after propensity score matching (PSM). Although the LCSS was better for lobectomy than for sub-lobar resection in patients with tumors ≤ 3 cm before PSM (p < 0.001), no significant difference in the LCSS was identified between the two treatment groups after PSM (p = 0.191). Multivariate Cox regression showed the elder age, male gender, squamous cell carcinoma (SQC) histology type, poor/undifferentiated grade and a large tumor size were associated with poor LCSS. The subgroup analysis of tumor sizes, histologic types and lymph nodes (LNs) dissection, there were also no significant difference for LCSS between lobectomy and sub-lobar resection. The sub-lobar resection was further divided into segmentectomy or wedge resection, and it demonstrated that no significant differences in LCSS were identified among the treatment subgroups either. Multivariate Cox regression analysis showed that the elder age, poor/undifferentiated grade and a large tumor size were a statistically significant independent factor associated with survival.Conclusion: In terms of LCSS, lobectomy has no significant advantage over sub-lobar resection in elderly patients with stage IA NSCLC if lymph node assessment is performed adequately. The present data may contribute to develop a more suitable surgical treatment strategy for the stage IA elderly NSCLC patients.

Background Superior vena cava syndrome (SVCS) is a common condition predominantly caused by lung cancer. The presence of symptoms of SVCS, such as elevated intracranial pressure and laryngeal edema, indicates an unfavorable prognosis for lung cancer patients. Superior vena cava (SVC) stenting is the first‐line treatment for SVCS. In this study, we retrospectively analyzed SVCS cases treated with stenting in our center to explore the safety and effectiveness of stenting in the treatment of SVCS. Methods We reviewed 16 patients with SVCS caused by lung cancer who were treated at our center with endovascular stenting between 2016 and 2018. Patient information such as age, sex, type of lung cancer, obstruction condition, complications, survival time, and postoperative treatments are summarized. Results There were no treatment‐related complications in the perioperative period in any of the patients. Examination at postoperative day 2 indicated that the accompanying SVCS symptoms had improved in all patients. The median survival of patients treated along with combined postoperative chemotherapy and antivascular targeted therapy reached seven months (1–18 months). Conclusions SVC stenting is effective as a first‐line treatment modality for patients with SVCS caused by lung cancer. In combination with other treatment modalities, it can significantly alleviate symptoms and reduce complications, and thus it plays an important role in the treatment of patients with SVCS caused by lung cancer.

Background: The aim of this study was to explore the factors associated with the occurrence of ISP after VATS to reduce the incidence of ISP and improve patients' quality of life.Methods: The data of patients were collected between June 2020 and August 2020 in the Department of Lung Cancer Surgery, Tianjin Medical University General Hospital. The angle of upper arm was measured intraoperatively. The patient's postoperative shoulder function was quantified using the Constant-Murley shoulder function rating score. The proportional hazards model was applied to identify multiple influence factors.Results: A total of 140 eligible patients met criteria. At postoperative day 3, only the age influenced patients' shoulder pain. At postoperative day 14, univariate and multivariate logistic regression analyses showed that age (odds ratio [OR]: 1.098 [1.046-1.152]; P < 0.001) and upper arm Angle A (OR: 1.064 [1.011-1.121]; P = 0.018) were independent risk factors for low shoulder function scores. However, height was its protective factor (OR: 0.923 [0.871-0.977]; P = 0.006). At postoperative day 42, univariate and multivariate logistic regression analyses showed that age (OR: 1.079 [1.036-1.124]; P < 0.001) was a risk factor for low shoulder function scores, and height (OR: 0.933 [0.886-0.983]; P = 0.009) was its protective factor. In contrast, upper arm Angle B was not statistically associated with low shoulder function scores (P>0.05). In addition, the reduction in ipsilateral Shoulder scores after surgery was higher in patients with more than 113° of angle A (P = 0.025).Conclusion: ISP was closely related to the angle of anterior flexion of the upper arm on the patient's operative side intraoperatively. The increase in the degree of postoperative shoulder injury is more pronounced for an anterior flexion angle of >113°. Therefore, we recommend that the angle of anterior flexion of the upper extremity should be <113° intraoperatively.

Background & Aims: Currently, there is a lack of effective tools for predicting the prognostic outcome of early‐stage lung cancer after surgery. We aim to create a nomogram model to help clinicians assess the risk of postoperative recurrence or metastasis.Materials and Methods: This work obtained 16,459 NSCLC patients based on SEER database from 2010 to 2015. In addition, we also enrolled 385 NSCLC patients (2017/01‐2019/06) into external validation cohort at Tianjin Medical University General Hospital. Univariable as well as multivariable Cox regression was carried out for identifying factors independently predicting OS. In addition, we built a nomogram by incorporating the above prognostic factors for the prediction of OS.Results: Tumor size was positively correlated with the risk of poor differentiation. Advanced age, male and adenocarcinoma patients were factors independently predicting poor prognosis. The risk of white race is higher, followed by Black race, Asians and Indians, which is consistent with previous study. Chemotherapy is negatively related to prognostic outcome in patients of Stage IA NSCLC and positively related to that in those of Stage IB NSCLC. Lymph node dissection can reduce the postoperative mortality of patients. AUCs of the nomograms for 1, 2, and 3‐year OS was 0.705, 0.712, and 0.714 for training cohort, while those were 0.684, 0.688, and 0.688 for validation cohort.Conclusions: The nomogram could be used as a tool to predict the postoperative prognosis of patients with Stage I non‐small cell lung cancer.

Background: Primary fallopian tube carcinoma (PFTC) is a malignant tumor of the female genital tract that mostly presents intraperitoneal dissemination in clinical practice. The incidence of upper anterior mediastinal metastasis in PFTCs is extremely rare. We herein report a rare case of PFTC mediastinal metastasis after radical resection. When anterior mediastinal metastasis of an unknown origin is encountered, the possibility of PFTC should be considered. Case presentation: A 68-year-old female who was previously diagnosed with PFTC after radical resection of a primary tumor in the fallopian tube was admitted to our department with a right anterior mediastinum mass. Radical resection of the mediastinal mass was performed, and poorly differentiated metastatic adenocarcinoma of the fallopian tube was confirmed. There was no recurrence in the 24 months after the curative operation. Conclusion: To our knowledge, no mediastinal metastasis of PFTC has been reported yet. Thus, we presented this rare case indicating the heterogeneity of this malignant disease and to draw attention to the occasional distant metastasis of PFTC in clinical practice.
