Sublobectomy

BACKGROUND: Controversy surrounds the efficacy of adjuvant chemotherapy (ACT) in the treatment of stage I lung adenocarcinoma (LUAD). The objective of this study was to examine the impact of the maximum standardized uptake value (SUVmax) as measured by 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) on the efficacy of ACT in patients diagnosed with stage I LUAD. METHODS: We scrutinized the medical records of 928 consecutive patients who underwent complete surgical resection for pathological stage I LUAD at our institution...

BACKGROUND: Due to the widespread use of imaging techniques, the detection rate of early-stage lung cancer has increased. Video-assisted thoracoscopic surgery (VATS) sublobectomy has emerged as a prominent alternative to lobectomy, offering advantages like reduced resection range, better preservation of lung function, and enhanced postoperative quality of life. However, sublobectomy is more intricate than lobectomy, necessitating a higher level of surgical proficiency and anatomical understanding...

BACKGROUND: The prognosis of limited-stage small cell lung cancer (LS-SCLC) after surgery usually is estimated at diagnosis, but how the prognosis actually evolves over time for patients who survived for a predefined time is unknown. METHODS: Data on patients with a diagnosis of LS-SCLC after surgery between 2004 and 2015 were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. The 5-year conditional cancer-specific survival (CCSS) and conditional overall survival (COS) were calculated...

BACKGROUND: Sublobar resection is gradually becoming a standard treatment for small-sized (≤2 cm) peripheral non-small cell lung cancer (NSCLC), with lung adenocarcinoma (LADC) being the most frequent histologic subtype. However, the prognostic predictors for preoperatively determining whether sublobectomy is feasible for patients with early LADC have not yet been well identified. Therefore, this study aimed to investigate the clinicopathological and computed tomography (CT) features associated with the recurrence-free survival (RFS) of patients with small-sized invasive LADC (SILADC) after sublobar resection...

PURPOSE: The NCCN guidelines do not recommend surgery for T3-4N0M0/T1-4N1-2M0 small cell lung cancer (SCLC) due to a lack of evidence. METHODS: Data of patients with T3-4N0M0/T1-4N1-2M0 SCLC were extracted from the Surveillance, Epidemiology, and End Results (SEER) database to determine the impact of surgery on this population. The Kaplan-Meier method, univariable and multivariable Cox proportional hazard regression, and propensity score matching (PSM) were used to compare the overall survival (OS) between the surgery and non-surgery groups...

PURPOSE: The new grading system for invasive nonmucinous lung adenocarcinoma (LUAD) in the 2021 World Health Organization Classification of Thoracic Tumors was based on a combination of histologically predominant subtypes and high-grade components. In this study, a model for the pretreatment prediction of grade 3 tumors was established according to new grading standards. METHODS: We retrospectively collected 399 cases of clinical stage I (cStage-I) LUAD surgically treated in Tianjin Chest Hospital from 2015 to 2018 as the training cohort...

PURPOSE: Functional preserving sublobectomy (FPSL), a novel balancing strategy for segmentectomy and wedge resection, allows rapid and accurate removal of invisible nodules without the use of any preoperative localization markers. This study aimed to share single-center experience of lateral dorsal basal lung resection based on FPSL, so as to provide new surgical options for thoracic surgeons. METHODS: A retrospective analysis was performed on 13 patients who underwent thoracoscopic basal lung resection after FPSL at XX hospital from January 2021 to August 2022...

PURPOSE: No consensus on a grading system for invasive lung adenocarcinoma had been built over a long period of time. Until October 2020, a novel grading system was proposed to quantify the whole landscape of histologic subtypes and proportions of pulmonary adenocarcinomas. This study aims to develop a deep learning grading signature (DLGS) based on positron emission tomography/computed tomography (PET/CT) to personalize surgical treatments for clinical stage I invasive lung adenocarcinoma and explore the biologic basis under its prediction...

More and more patients with small cell lung cancer (SCLC) have received surgical treatment in the last 20 years. This meta-analysis compared whether surgical treatment can bring greater survival benefits to patients with stage I-III SCLC compared with chemotherapy, radiotherapy and chemoradiotherapy. Pubmed, Embase, Web of Science, Cochrane library database, and ClinicalTrials were searched for relevant articles. The main outcomes were overall survival (OS), reported as hazard ratios (HRs), and 95% confidence intervals (CIs)...

BACKGROUND: Simultaneous bilateral thoracoscopic lung resection (SBTLR) has been shown to be a feasible and efficacious approach for a wide range of pulmonary conditions. Our aim was to evaluate the impact of different procedures on surgical outcomes in patients receiving SBTLR. METHODS: Between 2012 and 2021, 207 patients with bilateral lung neoplasms who underwent SBTLR were retrospectively reviewed. Fifty-one patients received ipsilateral plus contralateral lobectomy or sublobectomy (lobar group), whilst 156 patients received bilateral sublobectomy (sublobar group)...

PURPOSE: Surgical resection is cornerstone treatment for early-stage non-small cell lung cancer (NSCLC) and offers a chance for cure. This study was conducted to determine current surgical treatment patterns and outcomes of Chinese patients with NSCLC. METHODS: Data of patients with histologically confirmed NSCLC of stages IA-IIIA and who underwent surgery between July 2014 and July 2020 were retrospectively collected from 9 tertiary hospitals in China. Cox model was used for multivariate analyses...

INTRODUCTION: Studies investigating surgery for second primary non-small cell lung cancer (SP) patients are rare. The aim of this study was to explore the effects of surgical methods and regional lymph node (LN) dissection on lung cancer-specific mortality (LCSM) in stage I SP patients following surgery for stage I first primary non-small cell lung cancer (FP). METHODS: Data on patients diagnosed with stage I SP after surgery for stage I FP were extracted from the Surveillance, Epidemiology, and End Results (SEER) database...

BACKGROUND: The standard surgical procedure for ≤ 2 cm non-small cell lung cancer (NSCLC), including the number of lymph nodes sampled (nLN) and surgical modality, remains controversial. This study was designed to determine the optimal cohort in which sublobectomy could be an alternative to lobectomy. MATERIALS (OR PATIENTS) AND METHODS: Patients from 1998 to 2017 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. The optimal cutoff value of nLN was identified using a restrictive cubic spline graph (RCS)...

BACKGROUND: According to the JCOG0802 study, there were many non-cancer-related deaths in the lobectomy group. Meanwhile, the median age of the enrolled patients in the JCOG0802 study was 67 years old. Whether this difference in perioperative outcomes and survival outcomes is related to age remains unknown. We aim to investigate whether the sublobectomy was comparable to lobectomy in elderly (≥ 75 years old) patients with peripheral solid-dominant [50% ≤ consolidation tumor ratio (CTR) ≤ 1] and diameter ≤ 2 cm non-small cell lung cancer (NSCLC)...

BACKGROUND: Ground glass opacity (GGO) is associated with favorable survival in lung cancer. However, the relevant evidence of the difference in prognostic factors between GGO and pure-solid nodules for pathological stage I invasive adenocarcinoma (IAC) is limited. We aimed to identify the impact of GGO on survival and find prognostic factor for part-GGO and pure-solid patients. METHODS: Between December 2007 and August 2018, patients with pathological stage I IAC were retrospectively reviewed and categorized into the pure-GGO, part-GGO, and pure-solid groups...

OBJECTIVE: Microwave ablation (MWA) is a safe and effective local therapy, however, its efficacy in stage I subpleural nonsmall cell lung cancer (NSCLC) compared to that of sublobar resection (SLR) is unclear. This study aimed to compare the efficacy of the two treatments for stage I NSCLC ≤1 cm from the pleura. METHODS: After propensity score matching (PSM), 70 patients with stage I subpleural NSCLC who underwent either SLR or MWA (35 patients each) from 2014 to 2018 were included...

Consolidation tumor ratio (CTR) is a hot issue in lung cancer imaging studies in recent years. It is defined as the proportion of the maximum consolidation diameter divided by the maximum tumor diameter in the lung window scanned by high resolution computed tomography (HRCT). Many studies have also confirmed that it can be used as an indicator to identify whether a lung tumor is benign or malignant at the early stage, the main basis on which to decide whether sublobectomy can be performed, and is an independent factor for the recurrence and prognosis of early-stage lung cancer...
