- Abstract
Aim Methods Results Conclusions To further elucidate the prognostic factors of non‐small‐cell lung cancer (NSCLC) patients with T2aN0M0 (stage IB) who underwent surgical treatment.We retrospectively analyzed the data of stage IB NSCLC patients who underwent surgical treatment at our center from October 2013 to September 2016. Eighty patients were enrolled. We analyzed their overall survival (OS) and disease‐free survival (DFS) using the Kaplan–Meier method.In univariable analysis, adenosquamous carcinoma (ASC) was significantly associated with inferior DFS (p = 0.036, p = 0.037) and OS (p = 0.001, p = 0.003) in all stage IB patients and those who only accepted surgery. Patients with a number of N2 lymph node dissections of ≥3 regions (N2‐LSNDr) exhibited better DFS (p = 0.020, p = 0.005) and OS (p = 0.003, p = 0.001) in all stage IB patients and those who only accepted surgery. In addition, advanced age (≥70 years old) is an adverse factor for DFS (p = 0.049) and OS (p = 0.018) among patients who did not receive adjuvant chemotherapy following surgery. In multivariable analyses, patients with N2‐LSNDr exhibited a longer OS (p = 0.045) in all enrolled patients; patients with N2‐LSNDr (p = 0.016) and younger age (p = 0.021) demonstrated a superior OS in patients who only received surgery.We found that N2‐LSNDr were independent influencing factors affecting the prognosis in all included stage IB patients and stage IB patients without adjuvant chemotherapy. ASC was associated with worse prognosis of T2aN0M0 NSCLC. Older age is an independent prognostic factor of the worst OS in stage IB patients without adjuvant chemotherapy. [ABSTRACT FROM AUTHOR]

Background: Lymph node (LN) metastasis status is the decision‐making basis for the surgical procedure and adjuvant therapy modalities. Fewer studies have previously focused on LN metastasis in N1 station, especially on peripheral lymph node (PLN) metastasis in N1 station. This study aimed to reveal the metastasis status of PLN of non‐small cell lung cancer (NSCLC), and investigate its effects on N staging. Methods: We retrospectively evaluated a consecutive series of patients who underwent curative resection for histologically confirmed N1 NSCLC. Propensity score matching (PSM) was used to analyze the effects of PLN on N staging. Results: A total of 105 patients with confirmed pathological N1 (pN1) stage NSCLC with solitary nodule and without neoadjuvant therapy were enrolled into the study: 55 patients had intraperipheral LN metastasis (IPLNM), and 50 patients had extra‐peripheral LN metastasis (EPLNM). Before PSM analysis, type of location (P = 0.002), surgical procedure (P = 0.008), number of positive LNs (P = 0.029), number of LNs removed (P = 0.010), lobe of lung cancer (P = 0.031), and vascular invasion (P = 0.049) showed significant differences between the two groups. After PSM analysis, statistically there were differences in type of location (P = 0.034), number of positive LNs (P = 0.008) and vascular invasion (P = 0.049) between them. Conclusion: PLN metastasis was a quite common pattern of LN metastasis in N1 station of NSCLC. IPLNM occurred more frequently in central NSCLC and NSCLC with vascular invasion, and thoracotomy was likely to secure more accurate PLN staging. Clinicians should pay great attention to PLN dissection. Follow‐up data will be needed in order to detect the prognosis of IPLNM patients. [ABSTRACT FROM AUTHOR]

Background: This study aimed to examine the treatment and prognosis of patients with type B2 + B3 thymoma and compare it with those patients with type B2 and B3 thymoma. Methods: We conducted a retrospective analysis of the results of 39 patients with type B2 + B3 thymoma, 133 patients with type B2 thymoma, and 64 patients with type B3 thymoma. The Kaplan–Meier technique was used to generate survival curves. For multivariate analysis, the Cox proportional hazard model was applied. Results: With a median follow‐up of 60 months (range: 1–128 months), the percentage of patients with tumor, node, metastasis (TNM) stage III and IV disease gradually increased from 19.5% to 25.6% to 35.9% among those with histological subtypes B2, B2 + B3, and B3, respectively, p = 0.045. Twenty‐three patients experienced recurrence or metastasis. The total 10‐year progression‐free survival (PFS) rates were 86.0% overall (85.0% in type B2, 87.2% in type B2 + B3, and 87.5% in type B3). Age, R0 resection, and Masaoka–Koga stage were found to have a significant on PFS in all patients. There was no statistically significant difference in PFS between different histotypes of thymoma, p = 0.650. PFS was predicted by R0 resection in all histotypes and by the Masaoka–Koga stage in the type B2 subgroup. Conclusion: Combining the two staging methods to guide the diagnosis and treatment of patients with B2 + B3 thymoma is recommended. R0 resection is recommended to reduce recurrence. Patients with B2 + B3 thymoma have a prognosis similar to those with a B2 thymoma or a B3 thymoma alone. [ABSTRACT FROM AUTHOR]

Background: Patients with small‐cell lung cancer (SCLC) have a high incidence of synchronous brain metastases (SBM) and a poor prognosis, which causes a heavy burden of morbidity and mortality. A better understanding of the demographic and tumor‐specific characteristics of these patients is critical to guiding clinical practice. The purpose of this study was to investigate the predictive and prognostic value of the clinical characteristics of SCLC patients with SBM at initial diagnosis. Methods: This is a retrospective study based on the data in the latest Surveillance, Epidemiology, and End Results (SEER) version which was released in 2021 for patients diagnosed with SCLC in the presence or absence of SBM from 2010 to 2018. Multivariable logistic regression was performed to identify predictors of the presence of SBM at the initial diagnosis. Kaplan–Meier curves and multivariable Cox regression models were built to compare the prognosis of patients with different clinical characteristics and treatments. Results: A total of 33,169 SCLC patients were enrolled in this study, including 5711 (17.2%) patients with SBM and 27,458 (82.8%) patients without SBM. Patients who are black(HR = 1.313, 95% CI = 1.167–1.478, p < 0.001), higher T stage (T2, HR = 1.193, 95%CI = 1.065–1.348, p = 0.005; T3, HR = 1.169, 95%CI = 1.029–1.327, p = 0.016; T4, HR = 1.259, 95%CI = 1.117–1.418, p < 0.001), lung metastases (HR = 1.434, 95%CI = 1.294–1.588, p < 0.001) and bone metastases (HR = 1.311, 95% CI = 1.205–1.426, p < 0.001) had greater odds of SBM at initial diagnosis. The median overall survival (OS) for SCLC patients with SBM was 5.0 months. Multivariable Cox regression revealed that age ≥ 65 (HR = 1.164, 95% CI = 1.086–1.247, p < 0.025), singled (HR = 1.095, 95% CI = 1.020–1.174, p = 0.012), higher T stage (T3, HR = 1.265, 95% CI = 1.123–1.425, p < 0.001; T4, HR = 1.192, 95% CI = 1.066–1.332, p = 0.002), higher N stage (N2, HR = 1.347, 95%CI = 1.214–1.494, p < 0.001; N3, HR = 1.452, 95%CI = 1.292–1.632, p < 0.001), liver metastases (HR = 1.415, 95%CI = 1.306–1.533, p < 0.001), and bone metastases (adjusted HR = 1.126, 95%CI = 1.039–1.221, p = 0.004). Analysis of treatment regimens showed that patients who received combinational treatment exhibited longer OS than chemotherapy or radiotherapy alone, and surgery combined with chemotherapy and radiotherapy exhibited the longest OS. Conclusions: In this study, we identified risk factors for SBM in SCLC patients and prognostic indicators among this patient population. We also found that patients who received different therapeutic strategies exhibited significant difference on OS, which will provide evidence‐based support for treatment options.

Background: Lung squamous cell carcinoma (LUSC), one of the main pathological types of lung cancer, has led to consequential socioeconomic burden. Ferroptosis is an iron‐dependent form of cell death process with potentials for therapeutic target in various kinds of tumors. However, whether ferroptosis‐related genes (FRGs) are associated with the prognosis of LUSC patients is still unclear. The aim of this study was to establish a FRGs‐based signature which could stratify patients with LUSC. Methods: The RNA sequencing profiles and corresponding clinical data of LUSC patients were retrieved from The Cancer Genome Atlas (TCGA) database and Gene Expression Omnibus (GEO) dataset. A FRG‐based signature was developed using the TCGA‐LUSC cohort and validated in the GEO cohort. Gene set enrichment analysis (GSEA) and analysis of immune cell characteristics were conducted to assess the relationship between FRGs and biological function or immune status. A nomogram based on selected clinical factors and the risk scores which were generated from the FRG‐based signature was developed using the TCGA cohort and validated in the GEO cohort. Results: A set of 16 FRGs, significantly associated with overall survival (OS) in the TCGA cohort, was identified and could classify LUSC patients into two risk groups. Kaplan–Meier analysis illustrated that the survival rate of the high‐risk group was significantly lower than the low‐risk group. Assessment and external validation of the signature showed that the survival predictive performance of this signature was adequate. Additionally, multiple pathways and functions were enriched through GSEA and the analysis of immune cell characteristics showed significantly different abundances of immune cells among the two risk groups. Finally, a nomogram integrating the FRG‐based signature and selected clinical factors was also developed and assessed in both the TCGA and GEO cohort. Conclusion: This study indicated the association between the FRGs and prognosis of patients with LUSC. Targeting ferroptosis may serve as a novel potential therapeutic alternative for LUSC.

Background and Objectives: Primary diaphragm tumors are rare. The aim of this study was to explore the clinicopathological features of primary diaphragm tumor patients who underwent surgical treatment in our center to improve the diagnosis and treatment of this disease. Methods: Clinical data of patients with primary diaphragm tumor who underwent surgery in our hospital from 2004 to 2019 were reviewed and analyzed. Results: A total of 18 patients were enrolled. The male:female ratio was 8:10, and the median age was 58 years old (35–74 years old). Most patients included in this study had no typical clinical symptoms. Nine tumor cases were distributed in the left and right diaphragms separately, whereas 11 cases were located at the diaphragm angle. The diaphragm of 12 patients was reconstructed by direct suture. All postoperative pathologies showed that the tumors were benign, and cysts were observed in most of the cases (5/18). Conclusions: There are no difference in distribution of gender and distribution on both sides of the diaphragm. In addition, primary diaphragm tumor is common in middle‐age patients. Most cases occur in the diaphragm angle and are characterized by cyst lesions. Surgical resection is an effective treatment option for primary diaphragm tumor. [ABSTRACT FROM AUTHOR]

Background: The management of ground‐glass opacities (GGOs) depends mainly on personal experience. In clinical practice, benign GGOs are not rare in resected specimens, for which operations may be avoided. We retrospectively compared the clinical features of resected GGOs to identify differential diagnostic characteristics. Methods: Among 1456 patients with suspected malignant GGOs who underwent surgical resection, 105 patients (35 with benign GGOs and 70 matched controls with malignant GGOs) were included. Clinical characteristics, including demographics and radiologic, surgical and pathologic characteristics, were collected. Results: The smoking index (P = 0.044), frequency of coughing (P = 0.026), GGO size (P = 0.003), size change during follow‐up (P = 0.011), location (P = 0.022), presence of air bronchogram sign (P = 0.004), distance to the pleura (P = 0.021) and positron emission tomography/computed tomography (PET/CT) appearance (P = 0.003) showed significant differences between the benign and malignant groups. Pathologically, the resected benign GGOs included focal fibrosis (17), inflammation or infection (seven), lymphoproliferative disorder (one), hamartoma (three), inflammatory myofibroblastic tumor (two), hemangioma or vascular malformation (two), endometriosis (two) and pulmonary cyst (one). Conclusions: A higher smoking index, coughing, larger size, similar or increased size during follow‐up, location in the upper and middle lobes, air bronchogram sign on CT, lesion margin to pleura distance over 1 cm, and malignant tendency on PET/CT reports were associated with malignant GGOs. Relatively active surgical interventions could be considered for GGOs highly suspected of malignancy. [ABSTRACT FROM AUTHOR]
