Abstract
INTRODUCTION There has been an increasing interest in the risk of lung cancer related to rheumatoid arthritis (RA). We investigated the association between RA and the risk of lung cancer with consideration of key confounding factors, including RA serostatus and smoking status. METHODS Using a nationwide database, we identified 51,899 patients with newly diagnosed RA between 2010 and 2017, which were matched by sex and age at a 1:5 ratio with 259,495 non-RA population. The association of lung cancer and RA was investigated using Cox regression analyses. Stratified analyses by smoking status, sex, age, and comorbidity of interstitial lung disease were conducted using the same Cox modeling. RESULTS During 4.5 years of follow-up, the adjusted hazard ratio of lung cancer in the patients with RA was 1.49 (95% confidence interval: 1.34-1.66). Compared with the patients with seronegative RA, an increased risk of lung cancer was not considerable in the patients with seropositive RA. In the stratified analyses, the increased risk of lung cancer was more prominent in current or previous heavy smokers with RA (interaction p value of 0.046) and male patients (interaction p < 0.001), whereas there was no substantial effect associated with age or interstitial lung disease status. CONCLUSIONS Patients with RA had an increased risk of lung cancer compared with the non-RA group, and the risk did not differ by RA serostatus. There is a need for increased awareness of smoking cessation and potentially for regular lung cancer screening with proper risk stratification in patients with RA.

Abstract
OBJECTIVE To propose a new ypTNM grouping system to address these limitations and improve prognostic relevance. SUMMARY BACKGROUND DATA The current 8th edition of the American Joint Committee on Cancer (AJCC) ypStage system shows unsatisfactory prognostic relevance in patients with esophageal squamous cell carcinoma (ESCC) treated with neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy. METHODS The study cohort included 501 ESCC patients who received nCRT followed by esophagectomy at the Samsung Medical Center in Korea between 1994 and 2018 (development cohort) and 422 patients treated at Asan Medical Center (validation cohort). Recursive partitioning with a tree-structured regression model was used to develop and validate a new ypStage grouping system. RESULTS In the new ypStage grouping system, ypStage I includes ypT0N0 only; ypStage II includes ypTis-T2N0 or ypT0-T2N1; ypStage III includes ypT3N0-N1; and ypStage IV includes ypT4N0-N1 or ypTanyN2-3. This system adequately addressed the limitations of the existing AJCC classification system, including overlapping and reversal of survival rates. Moreover, the discrimination ability of the new system was higher than that of the existing system [concordance-index (C-index): 61.9%] in the development (C-index: 66.6%) and validation (C-index: 66.0%) cohorts. NRIe was 0.17 [95% confidence interval (CI): 0.09-0.26, P-<0.001) and 0.18 (95% CI: 0.10-0.27, P-<0.001)] in the development and validation cohorts, respectively. CONCLUSIONS The current study proposes a clear revised version of the 8th edition of the AJCC ypStage grouping system that exhibits superior prognostic stratification in patients with ESCC treated with nCRT followed by esophagectomy.

Abstract
Background Cervical esophageal cancer is a rare malignancy that requires specialized care. While definitive chemoradiation is the standard treatment approach, surgery remains a valuable option for certain patients. This study examined the surgical outcomes of patients with cervical esophageal cancer. Methods The study involved a retrospective review and analysis of 24 patients with cervical esophageal cancer. These patients underwent surgical resection between September 1994 and December 2018. Results The mean age of the patients was 61.0±10.2 years, and 22 (91.7%) of them were male. Furthermore, 21 patients (87.5%) had T3 or T4 tumors, and 11 (45.8%) exhibited lymph node metastasis. Gastric pull-up with esophagectomy was performed for 19 patients (79.2%), while 5 (20.8%) underwent free jejunal graft with cervical esophagectomy. The 30-day operative mortality rate was 8.3%. During the follow-up period, complications included leakage at the anastomotic site in 9 cases (37.5%) and graft necrosis of the gastric conduit in 1 case. Progression to oral feeding was achieved in 20 patients (83.3%). Fifteen patients (62.5%) displayed tumor recurrence. The median time from surgery to recurrence was 10.5 months, and the 1-year recurrence rate was 73.3%. The 1-year and 3-year survival rates were 75% and 33.3%, respectively, with a median survival period of 17 months. Conclusion Patients with cervical esophageal cancer who underwent surgical resection faced unfavorable outcomes and relatively poor survival. The selection of cases and decision to proceed with surgery should be made cautiously, considering the risk of severe complications.

Abstract
BACKGROUND This retrospective study was performed to investigate the survival differences according to the pathologic status after neoadjuvant chemotherapy followed by surgery in esophageal squamous cell carcinoma (ESCC), and to investigate whether current AJCC 8th ypStage can predict survival accurately. METHODS Data of 563 patients who received neoadjuvant therapy and esophagectomy for ESCC between 1994 and 2018 were retrospectively reviewed. RESULTS The mean age was 62.00 ± 8.01 years, of which 524 (93.1%) were males. The median follow-up period was 29.12 months. A total of 153 (27.1%) patients showed pathologic complete response (pCR) and 92 (16.3%) patients showed pCR of the primary lesion with residual metastatic lymph nodes (ypT0N +). A total of 196 (35%) and 122 (21.6%) patients showed ypT + N + and ypT + N, respectively. The 5-year overall survival (OS) of each group was 75.1% (CR), 42.4% (ypT + N0), 54.9% (ypT0N +), and 26.1% (ypT + N +); CR patients showed better survival than the other groups, and no survival differences were found in the 5-year OS between ypT + N0 and ypT0N + patients (p = 0.811). In ypStage I, there were survival differences between ypT0N0 and ypTis-2N0 patients, and ypT1N0 (ypStage I) and ypT0N1 (ypStageIIIA) showed similar OS (5-year OS in 49.3% vs. 67.1%, p = 0.623). CONCLUSIONS pCR offers long-term survival in patients; however, survival significantly declines with the presence of residual primary lesion and nodal metastases.

Abstract
BACKGROUND Invasive mucinous adenocarcinoma (IMA) is distinct from non-mucinous adenocarcinoma, but studies on recurrent IMA are scarce. Thus, this study aimed to evaluate the recurrence patterns of IMA and the role of pulmonary local therapy (LT) in resectable pulmonary recurrence of IMA. METHODS The study reviewed 403 patients with surgically resected IMA between 1998 and 2018. The recurrence patterns were categorized as solitary pulmonary recurrence (SPR), multiple pulmonary recurrence (MPR), and extra-pulmonary recurrence (EPR). The clinicopathologic characteristics, overall survival (OS), and post-recurrence survival (PRS) were analyzed according to the recurrence pattern and LT administration. RESULTS Recurrences were found in 91 (22.6%) patients, including 18 patients with SPR, 37 patients with MPR, and 36 patients with EPR. Compared with the MPR and EPR groups, the SPR group had a longer disease-free interval (32.5 vs. 9.6 vs. 10.1 months, respectively; p < 0.01) and a better OS (5-year OS: 88.5%, 41.5%, and 22.9%, respectively; p < 0.01). In case of resectable pulmonary recurrence, pulmonary LT was administered to 15 patients with SPR and 3 patients with MPR. These patients showed a better 5-year PRS than the other patients with pulmonary recurrence (86.3% vs. 30.4%; p < 0.01). Notably, long-term survival was observed for one patient with MPR undergoing LT and two patients with SPR undergoing a second LT for a second pulmonary recurrence. CONCLUSIONS In this series, the patients with recurrent IMA showed different prognoses according to the recurrence pattern. The patients with pulmonary recurrence of IMA undergoing LT showed a favorable prognosis, suggesting the potential role of LT for resectable pulmonary recurrence of IMA.

Abstract
OBJECTIVES We examined the associations of socioeconomic factors, health behaviors, and comorbidities with early-onset lung cancer. METHODS The study included 6,794,287 individuals aged 20-39 years who participated in a Korean national health check-up program from 2009 to 2012. During the follow-up period, 4,684 participants developed lung cancer. Multivariable Cox regression analysis was used to estimate the independent associations of potential risk factors with incident lung cancer. RESULTS Older age (multivariable hazard ratio [mHR], 1.13; 95% confidence interval [CI], 1.12 to 1.14) and female sex (mHR, 1.62; 95% CI, 1.49 to 1.75) were associated with increased lung cancer risk. Current smoking was also associated with elevated risk (<10 pack-years: mHR, 1.12; 95% CI, 1.01 to 1.24; ≥10 pack-years: mHR, 1.30; 95% CI, 1.18 to 1.45), but past smoking was not. Although mild alcohol consumption (<10 g/day) was associated with lower lung cancer risk (mHR, 0.92; 95% CI, 0.86 to 0.99), heavier alcohol consumption (≥10 g/day) was not. Higher income (highest vs. lowest quartile: mHR, 0.86; 95% CI, 0.78 to 0.94), physical activity for at least 1,500 metabolic equivalent of task-min/wk (vs. non-exercisers: mHR, 0.83; 95% CI, 0.69 to 0.99) and obesity (vs. normal weight: mHR, 0.89; 95% CI, 0.83 to 0.96) were associated with lower lung cancer risk, whereas metabolic syndrome was associated with increased risk (mHR, 1.13; 95% CI, 1.03 to 1.24). CONCLUSIONS In young adults, age, female sex, smoking, and metabolic syndrome were risk factors for early-onset lung cancer, while high income, physical activity, and obesity displayed protective effects.

Abstract
BACKGROUND AND OBJECTIVE This study aimed to evaluate the longitudinal changes in cardiopulmonary function (CPF) and identify predictors of cardiopulmonary recovery failure after lung cancer surgery. METHODS Data was obtained from a prospective CATCH-LUNG cohort study, where patients were divided into two groups based on 6-min walk distance (6MWD) at baseline and 6 months after surgery. CPF recovery failure was defined as a participant whose 6MWD dropped over 50 m from baseline to 6 months after surgery. Patients with a baseline 6MWD less than 400 m were excluded. The analysis was investigated using mixed effects models, and the relative estimates for the predictors were expressed relative risk (RR) and 95% CI using a Poisson regression. RESULTS Among 419 patients, 24.1% and 17.7% showed failure of CPF recovery at 6 months and 1 year after surgery, respectively. In the multivariable analysis, baseline step count [RR per 1000 steps lower = 1.05 (95% CI, 1.01-1.09)], baseline dyspnoea [RR per 10 points higher = 1.15(1.07-1.23)], decreased FEV1 % predicted from baseline to 2 weeks after surgery [RR per 10% lower = 1.30(1.10-1.53)] and decreased moderate-to-vigorous physical activity (MVPA) from baseline to 2 weeks [RR = 1.95(1.22, 3.11)] or persistent low MVPA at baseline and 2 weeks after surgery [RR = 1.63(1.04, 2.54)] were significant factors for loss of CPF. CONCLUSION The inability to recover CPF at 6 months after surgery was linked to reduction of lung function and MVPA from baseline to 2 weeks as well as baseline physical activity (PA) and dyspnoea. These results imply that engagement of perioperative PA is necessary to facilitate recovery of CPF after lung cancer surgery.

Abstract
PURPOSE/OBJECTIVE(S) The local ablative therapy for oligometastatic disease (OMD) has the potential to delay further metastases and improve survival. However, it has not been fully elucidated how prostate primary radiotherapy (PPR) and metastasis-directed radiotherapy (MDR) affect prognosis in each different OMD scenario. Herein, we tried to provide efficacy and future perspectives for MDR in oligometastatic prostate cancer. MATERIALS/METHODS Patients diagnosed with prostate cancer between 2010 and 2019 and treated for OMD (≤5 active lesions), which occurred synchronously or metachronously, were included. All patients received MDR at all detected lesions (OMDRT). OMDRT which was performed as soon as OMD was detected was classified as early, and OMDRT for progressions after hormone therapy was classified as late. The primary endpoint was survival after OMDRT, and timing of progression after RT was also analyzed. RESULTS A total of 82 patients with oligometastatic prostate cancer received OMDRT. Among 36 patients with synchronous OMD, 58% received PPR at diagnosis, and 64% received early OMDRT. Among 46 patients with metachronous OMD, 80% received early OMDRT, and 28 received sequential OMDRT for repetitive OMD events. With a median follow-up of 32 months after OMDRT, 54 patients experienced progression and 5-year survival was 78%. Survival was highest in patients with synchronous OMD and early RT (5-year 86%), and 5-year survival of patients with metachronous OMD and early RT was significantly higher than those with late RT (78% vs. 44%, p = 0.003). Survival of patients with synchronous OMD and PPR was significantly higher than those without PPR or with metachronous OMD (5-year 90% vs. 66%, p = 0.030), by delaying progressions (17.9 vs. 7.0 months, p = 0.005). CONCLUSION Survival gain could be achieved through OMDRT in oligometastatic prostate cancer, especially in synchronous OMD status. Also, it was possible to improve the prognosis further when OMDRT was performed early and with PPR.

Abstract
PURPOSE/OBJECTIVE(S) The pattern of locoregional recurrence specifically after robotic-assisted laparoscopic prostatectomy (RALP) for prostate adenocarcinoma is still unknown. In this study, we reviewed pelvic magnetic resonance images (MRI) after postoperative biochemical recurrence (BCR) and drew a map of locoregional recurrence to support evidence of determining the optimal target volume of salvage radiotherapy in a post-RALP BCR scenario. MATERIALS/METHODS We have retrospectively searched 7,583 prostate adenocarcinoma patients who have received RALP in our institution between January 2010 and December 2021, and found a pool of highly selected patients with gross tumor recurrence confirmed by post-BCR pelvic MRIs and did not have other histories of malignancy. BCR was defined as the serum PSA more or equal to 0.2 ng/mL, or three consecutive increases. Patients with serum PSA nadir more or equal to 0.2 ng/mL on the 90th postoperative day (POD 90) were excluded to guarantee successful tumor removal. We have reviewed serum PSA levels using R codes, MRI and pathological reports using Excel, and descriptive statistics using SPSS 25. The gross lesions were contoured on the correlating MRIs using MIM Maestro 7.1. The RT structure DICOM files were merged into a map using MATLAB 2022b. In addition, we have conducted Fisher exacted test, Mann-Whitney U test, and logistic regression to identify risk factors for regional recurrence. RESULTS A total of 173 patients were identified with locoregional recurrence from post-BCR pelvic MRIs, and 139 (80.3%) patients were in the high-risk group or very-high-risk group according to the NCCN guidelines: 57 (32.9%) patients with histological grade group 5, 50 (28.9%) patients with initial PSA over 20 ng/mL, 114 (65.9%) patients with extracapsular extension, 55 (31.8%) patients with seminal vesicle invasion, and 15 (9%) patients with pN1. The median follow-up was 4.7 (IQR 2.8-6.9) years for pelvic MRIs and 5.8 (IQR 4.0-8.6) years for serum PSA. The BCF survival was median of 10.7 (IQR 4.6-19.1) months, and the locoregional recurrence-free survival was median of 24.6 (IQR 9.7-49.4) months for this subgroup of patients. At first locoregional recurrence, 148 (85.5%) patients were local only, 20 (11.6%) patients were regional only, and 5 (2.9%) patients were both local and regional. Out of the 25 patients with regional recurrence, the incidence of gross tumor recurrence differed by nodal sites: 3 (12%) in perirectal space, 5 (20%) in internal iliac, 7 (28%) in obturator, 13 (52%) in external iliac, and 6 (24%) in common iliac lymph nodes. CONCLUSION We have found 173 patients and were able to map reliable gross tumor recurrence sites after RALP and confirmed by pelvic MRIs following BCR. The map supports evidence of using the existing consensus pelvic clinical target volume of salvage radiotherapy, in a post-RALP BCR scenario.

Abstract
PURPOSE Stereotactic body radiotherapy (SBRT) had been increasingly recognized as a favorable alternative to surgical resection in patients with high risk for surgery. This study compared survival outcomes between sublobar resection (SLR) and SBRT for clinical stage I non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Data were obtained from the Korean Association of Lung Cancer Registry, a sampled nationwide database. This study retrospectively reviewed 382 patients with clinical stage I NSCLC who underwent curative SLR or SBRT from 2014 to 2016. RESULTS Of the patients, 43 and 339 underwent SBRT and SLR, respectively. Patients in the SBRT group were older and had worse pulmonary function. The 3-year overall survival (OS) rate was significantly better in the SLR group compared with the SBRT group (86.6% vs. 57%, log-rank p < 0.001). However, after adjusting for age, sex, tumor size, pulmonary function, histology, smoking history, and adjuvant therapy, treatment modality was not an independent prognostic factor for survival (hazard ratio, 0.99; 95% confidence interval, 0.43 to 2.77; p=0.974). We performed subgroup analysis in the following high-risk populations: patients who were older than 75 years; patients who were older than 70 years and had diffusing capacity of lung for carbon monoxide ≤ 80%. In each subgroup, there were no differences in OS and recurrence-free survival between patients who underwent SLR and those who received SBRT. CONCLUSION In our study, there were no significant differences in terms of survival or recurrence between SBRT and SLR in medically compromised stage I NSCLC patients. Our findings suggest that SBRT could be considered as a potential treatment option for selected patients.

Abstract
PURPOSE This study aimed to investigate the efficacy of adjuvant chemotherapy after neoadjuvant chemoradiotherapy (CCRTx) followed by surgery in patients with esophageal squamous cell carcinoma (ESCC). MATERIALS AND METHODS We retrospectively analyzed the data from 382 patients who received neoadjuvant CCRTx and esophagectomy for ESCC between 2003 and 2018. RESULTS This study included 357 (93.4%) men, and the years median patient age was 63 (range, 40 to 84 years). Overall, 69 patients (18.1%) received adjuvant chemotherapy, whereas 313 patients (81.9%) did not. The median follow-up period was 28.07 months (interquartile range, 15.50 to 62.59). The 5-year overall survival (OS) and disease-free survival were 47.1% and 42.6%, respectively. Adjuvant chemotherapy did not improve OS in all patients, but subgroup analysis revealed that adjuvant chemotherapy improved the 5-year OS in patients with ypT+N+ (24.8% vs. 29.9%, p=0.048), whereas the survival benefit of adjuvant chemotherapy was not observed in patients with ypT0N0, ypT+N0, or ypT0N+. Multivariable analysis revealed that ypStage and adjuvant chemotherapy (hazard ratio, 0.601; p=0.046) were associated with OS in patients with ypT+N+. Freedom from distant metastasis was marginally different according to the adjuvant chemotherapy (48.3% vs. 41.3%, p=0.141). CONCLUSION Adjuvant chemotherapy after neoadjuvant therapy followed by surgery reduces the distant metastasis in ypT+N+ ESCC patients, thereby improving the OS. The consideration could be given to administration of adjuvant chemotherapy to ypT+N+ ESCC patients with tolerable conditions.

Abstract
PURPOSE/OBJECTIVE(S) This study aimed to develop a graded prognostic assessment (GPA) model integrating genomic characteristics in patients with elderly glioblastoma (eGBM), and compare the efficacy between conventionally fractionated radiotherapy (CFRT) vs. hypofractionated radiotherapy (HFRT) in each risk group. MATERIALS/METHODS Patients aged ≥65 years who underwent surgical resection followed by radiotherapy (RT) with or without temozolomide (TMZ) for newly diagnosed IDH-wildtype eGBM between 2006 and 2021 were included in this multicenter cohort study. Patients who were planned for a ≥6-week or ≤4-week radiotherapy were regarded as being treated with CFRT or HFRT, respectively. Based on the prognostic factors significantly identified through multivariate analysis for overall survival (OS), we developed the molecular GPA for eGBM (eGBM-molGPA) and assigned 0.0, 0.5, and 1.0 points in proportion to the corresponding hazard ratio (HR) of each factor. Then, the survival outcomes by treatment groups were evaluated according to the eGBM-molGPA scores. RESULTS A total of 334 and 239 patients who underwent CFRT and HFRT were included, respectively, and 86% of patients were treated with TMZ-based chemoradiation. With a median follow-up of 17.4 months for survivors, the median OS was 18.7 months for CFRT plus TMZ group, 15.1 months for HFRT plus TMZ group, and 10.4 months for RT alone group, respectively (all p<0.001). In the multivariate analysis, Karnofsky performance scale, surgical extent, TMZ, and the methylation status of the MGMT promoter were identified as strong prognostic factors for OS, with an estimated HR of greater than 1.5 (all p<0.001). Additionally, subventricular zone involvement, temporalis muscle thickness, RT regimen, and the mutation status of TERT promoter and TP53 gene were found to be significant prognostic factors for OS, with an estimated HR of less than 1.5. The eGBM-molGPA was established based on these prognostic factors (Table 1) and patients were allocated to three risk groups, which included high risk (total score of 3.0-4.5), intermediate risk (1.5-2.5), and low risk (0.0-1.0). Patients treated with CFRT plus TMZ had significantly improved OS compared to those treated with HFRT plus TMZ or RT alone in the low and intermediate risk groups (p<0.001). However, in the high-risk group, there was no significant difference in OS between treatment options (p = 0.770). CONCLUSION CFRT plus TMZ can be a more effective strategy for selected eGBM patients compared to HFRT. For high-risk patients, a protracted treatment schedule might not be beneficial. The novel eGBM-molGPA can be used as a clinical tool for choosing wisely among treatment options. Further prospective studies are warranted to establish optimal RT guidelines for eGBM patients.

Longitudinal Monitoring of Circulating Tumor DNA From Plasma in Patients With Curative Resected Stages I to IIIA EGFR-Mutant Non-Small Cell Lung Cancer. J Thorac Oncol 2023; 18:1199-1208. [PMID: 37308037 DOI: 10.1016/j.jtho.2023.05.027] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 05/17/2023] [Accepted: 05/17/2023] [Indexed: 06/14/2023]
Abstract
INTRODUCTION For patients with early stage EGFR-mutant-positive (EGFR-M+) NSCLC, curative surgery followed by adjuvant chemotherapy is considered the standard of care. This study evaluated the feasibility and efficacy of longitudinal monitoring of circulating tumor DNA (ctDNA) as a valuable biomarker for early detection of minimal residual disease (MRD) and provides identification of the group at high risk for recurrence in resected stages I to IIIA EGFR-M+ NSCLC. METHODS Between August 2015 and October 2017, a total of 278 patients with curative resected, stages I to IIIA (American Joint Committee on Cancer seventh version) common EGFR-M+ NSCLC were analyzed. Radiological follow-up was accompanied with longitudinal monitoring of ctDNA using a droplet-digital polymerase chain reaction from baseline (preoperative), 4 weeks after curative surgery, and follow-up per protocol until 5 years. The primary outcomes were disease-free survival (DFS) according to the status of ctDNA positivity at landmark points and the sensitivity of longitudinal monitoring of ctDNA. RESULTS Among 278 patients, preoperative baseline ctDNA was detected in 67 (24%) patients: 23% (stage IA), 18% (IB), 18% (IIA), 50% (IIB), and 42% (IIIA) (p = 0.06). Of patients with baseline ctDNA, 76% (51 of 67) had clearance at 4 weeks after surgery (postoperative). Patients were classified into the following three groups; group A, baseline ctDNA negative (n = 211) versus group B, baseline ctDNA positive but postoperative MRD negative (n = 51) versus group C, baseline ctDNA positive and postoperative MRD positive (n = 16). The 3-year DFS rate was significantly different among the three groups (84% for group A, 78% for group B, and 50% for group C, p = 0.02). After adjusting for clinicopathologic variables, ctDNA still remains an independent risk factor for DFS along with stage (p < 0.001) and micropapillary subtype (p = 0.02). With longitudinal monitoring of ctDNA, MRD was detected before radiological recurrence in 69% of patients with exon 19 deletion and in 20% with L858R mutation. CONCLUSIONS These results suggest that patients with baseline ctDNA-positive or MRD-positive status were associated with poor DFS in curative resected stages I to IIIA EGFR-M+ NSCLC and that longitudinal monitoring of ctDNA, a noninvasive method, might be useful to detect early recurrence before radiological recurrence.

Abstract
PURPOSE Fear of cancer recurrence (FCR) is a multidimensional phenomenon among cancer survivors. This cross-sectional study aimed to identify the prevalence of FCR and its predictors among survivors of non-small cell lung cancer (NSCLC) in Korea. METHODS Participants who finished NSCLC treatment one or more months prior completed the Korean version of Fear of Cancer Recurrence Inventory-Short Form (K-FCRI-SF) and the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30) at single tertiary hospital in Korea. Multivariate-adjusted logistic regression and stepwise backward selection were used to determine the potential predictors of FCR. RESULTS Of the total 949 participants (mean age 63.4 ± 8.8 years, 44.3% women), 55.8% had high FCR. Female (adjusted odds ratio [aOR] 1.44, 95% confidence interval [CI] 1.06-1.95), pathologic stage III (aOR 1.97, 95% CI 1.18-3.30), poor overall quality of life (aOR 1.42, 95% CI 1.03-1.95), poor emotional functioning (aOR 3.91, 95% CI 2.64-5.81), poor social functioning (aOR 1.87, 95% CI 1.31-2.68), and severe dyspnea (aOR 2.91, 95% CI 1.03-8.21) were independent predictors of high FCR. Old age (≥ 70 years) was included in the final model (aOR 0.74, 95% CI 0.51-1.06) but did not show clinical significance. CONCLUSIONS Our study demonstrated that high FCR was prevalent in NSCLC patients in Korea. To prevent this, we suggest screening and early detection of FCR based on sex, pathologic stage, quality of life, emotional and social functioning, and dyspnea. IMPLICATIONS FOR CANCER SURVIVORS Screening and early detection of FCR based on sex, pathologic stage, quality of life, emotional and social functioning, and dyspnea is suggested.

Abstract
OBJECTIVE The aim of this study was to validate the International Association for the Study of Lung Cancer (IASLC) residual tumor classification in patients with stage III-N2 non-small cell lung cancer (NSCLC) undergoing neoadjuvant concurrent chemoradiotherapy (nCCRT) followed by surgery. BACKGROUND As adequate nodal assessment is crucial for determining prognosis in patients with clinical N2 NSCLC undergoing nCCRT followed by surgery, the new classification may have better prognostic implications. METHODS Using a registry for thoracic cancer surgery at a tertiary hospital in Seoul, Korea, between 2003 and 2019, we analyzed 910 patients with stage III-N2 NSCLC who underwent nCCRT followed by surgery. We classified resections using IASLC criteria: complete (R0), uncertain (R[un]), and incomplete resection (R1/R2). Recurrence and mortality were compared using adjusted subdistribution hazard model and Cox-proportional hazards model, respectively. RESULTS Of the 96.3% (n = 876) patients who were R0 by Union for International Cancer Control (UICC) criteria, 34.5% (n = 3O2) remained R0 by IASLC criteria and 37.6% (n = 329) and 28% (n = 245) migrated to R(un) and R1, respectively. Most of the migration from UICC-R0 to lASLC-R(un) and IASLC-R1/R2 occurred due to inadequate nodal assessment (85.5%) and extracapsular nodal extension (77.6%), respectively. Compared to R0, the adjusted hazard ratios in R(un) and R1/R2 were 1.20 (95% confidence interval, 0.94-1.52), 1.50 (1.17-1.52) ( P fortrend = .001) for recurrence and 1.18 (0.93-1.51) and 1.51 (1.17-1.96) for death ( P for trend = .002). CONCLUSIONS The IASLC R classification has prognostic relevance in patients with stage III-N2 NSCLC undergoing nCCRT followed by surgery. The IASLC classification will improve the thoroughness of intraoperative nodal assessment and the completeness of resection.

Eur J Cardiothorac Surg 2023; 63:7143383. [PMID: 37099712 DOI: 10.1093/ejcts/ezad152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 03/26/2023] [Accepted: 04/05/2023] [Indexed: 04/28/2023] Open
Abstract
OBJECTIVES The aim of the study was to evaluate the clinical outcomes of patients with lung cancer in whom left ventricular ejection fraction (LVEF) was reduced. METHODS 9814 patients with lung cancer who underwent pulmonary resection from 2010 to 2018 were included for the study. Fifty-six (0.57%) patients had LVEFs equal or less than 45% and we performed propensity-score matching (1:3) to compare postoperative clinical outcomes and survival in 56 patients (reduced LVEF group) with those in 168 patients with normal LVEFs (nonreduced LVEF group). RESULTS The data of the reduced LVEF group and nonreduced group were matched and compared. The 30- (1.8%) and 90-day (7.1%) mortality rates were higher in the reduced LVEF group than those (0% for both 30- and 90-day mortality rates) in the nonreduced LVEF group (p < 0.001). The estimated rates of overall survival at 5-year point were similar in the non-reduced LVEF group (66.0%) and in the reduced LVEF group (60.1%). The estimated rates of overall survival at 5-year point were almost the same between in the nonreduced and reduced LVEF groups for clinical stage 1 lung cancer (76.8% vs 76.4%, respectively), but for stages 2 and 3, they were significantly better in the nonreduced LVEF group than in the reduced LVEF group (53.8% vs.39.8%, respectively). CONCLUSIONS Lung cancer surgery for selected patients with reduced LVEFs can yield favorable long-term outcomes despite the relatively high early mortality rate. A careful patient selection and meticulous postoperative care could further improve clinical outcome with reduced LVEF.

Abstract
BACKGROUND Pulmonary resection surgery causes severe postoperative pain and usually requires opioid-based analgesia, particularly in the early postoperative period. However, the administration of large amounts of opioids is associated with various adverse events. We hypothesized that patients who underwent pulmonary resection under an enhanced recovery after surgery (ERAS) program consumed fewer opioids than patients who received conventional treatment. METHODS A total of 2147 patients underwent pulmonary resection surgery between August 2019 and December 2020. Two surgeons (25%) at our institution implemented the ERAS program for their patients. After screening, the patients were divided into the ERAS and conventional groups based on the treatment they received. The 2 groups were then compared after the stabilized inverse probability of treatment weighting. The primary end point was the total amount of opioid consumption from surgery to discharge. The secondary end points included daily average and highest pain intensity scores during exertion, opioid-related adverse events, and clinical outcomes, such as length of intensive care unit (ICU) stay, hospital stay, and postoperative complication grade defined by the Clavien-Dindo classification. Additionally, the number of patients discharged without opioids prescription was assessed. RESULTS Finally, 2120 patients were included in the analysis. The total amount of opioid consumption (median [interquartile range]) after surgery until discharge was lower in the ERAS group (n = 260) than that in the conventional group (n = 1860; morphine milligram equivalents, 44 [16-122] mg vs 208 [146-294] mg; median difference, -143 mg; 95% CI, -154 to -132; P < .001). The number of patients discharged without opioids prescription was higher in the ERAS group (156/260 [60%] vs 329/1860 [18%]; odds ratio, 7.0; 95% CI, 5.3-9.3; P < .001). On operation day, both average pain intensity score during exertion (3.0 ± 1.7 vs 3.5 ± 1.8; mean difference, -0.5; 95% CI, -0.8 to -0.3; P < .001) and the highest pain intensity score during exertion (5.5 ± 2.1 vs 6.4 ± 1.7; mean difference, -0.8; 95% CI, -1.0 to -0.5; P < .001) were lower in the ERAS group than in the conventional group. There were no significant differences in the length of ICU stay, hospital stay, or Clavien-Dindo classification grade. CONCLUSIONS Patients who underwent pulmonary resection under the ERAS program consumed fewer opioids than those who received conventional management while maintaining no significant differences in clinical outcomes.

Diagnostic Performance of Endosonography to Detect Mediastinal Lymph Node Metastasis in Patients with Radiological N1 Non-Small Cell Lung Cancer. Cancer Res Treat 2023:crt.2022.1428. [PMID: 36915249 PMCID: PMC10372604 DOI: 10.4143/crt.2022.1428] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 02/28/2023] [Indexed: 03/06/2023] Open
Abstract
Purpose Guidelines recommend that non-small cell lung cancer (NSCLC) patients with suspected hilar lymph node (LN) metastases should undergo invasive mediastinal LN staging prior to surgical treatment via endosonography. We evaluated the diagnostic performance of endosonography for detecting occult mediastinal metastases (OMM) and determined the factors associated with OMM in NSCLC patients with radiological N1. Materials and Methods Patients with confirmed primary NSCLC with radiological N1 who underwent endosonography for nodal staging assessment from January 2013 to December 2019 were retrospectively analyzed. Results The prevalence of OMM was found to be 83/279 (29.7%) and only 38.6% (32/83) were diagnosed via endosonography. However, five of them were confirmed as N3 by endosonography. The overall diagnostic sensitivity, negative predictive value, accuracy, and area under the curve of endosonography were 38.6%, 79.4%, 81.7%, and 0.69, respectively. In multivariable analysis, central tumor (adjusted odds ratio [aOR], 2.05; 95% confidence interval [CI], 1.15-3.68; p=0.016), solid tumor (aOR, 10.24; 95% CI, 1.32-79.49; p=0.026), and adenocarcinoma (aOR, 3.01; 95% CI, 1.63-5.55; p<0.001) were related to OMM in radiological N1 NSCLC patients. Conclusion Although the sensitivity of endosonography for detecting OMM was only 40%, the prevalence of OMM was not low (30%) and some cases even turned out to be N3 diseases. Clinicians should be aware that OMM may be more likely in patients with central, solid, and adenocarcinomatous tumor when performing nodal staging in radiological N1 NSCLC via endosonography.

Abstract
BACKGROUND Interstitial lung abnormalities (ILAs) are associated with the risk of lung cancer and its mortality. However, the impact of ILA on treatment-related complications and survival in patients who underwent curative surgery is still unknown. RESEARCH QUESTION This study aimed to evaluate the significance of the presence of computed tomography-diagnosed ILA and histopathologically matched interstitial abnormalities on postoperative pulmonary complications (PPCs) and the long-term survival of patients who underwent surgical treatment for lung cancer. STUDY DESIGN AND METHODS A matched case-control study was designed to compare PPCs and mortality among 50 patients with ILA, 50 patients with idiopathic pulmonary fibrosis (IPF) and 200 controls. Cases and controls were matched by sex, age, smoking history, tumour location, the extent of surgery, tumour histology and pathological TNM stage. RESULTS Compared with the control group, the OR of the prevalence of PPCs increased to 9.56 (95% CI 2.85 to 32.1, p<0.001) in the ILA group and 56.50 (95% CI 17.92 to 178.1, p<0.001) in the IPF group. The 5-year overall survival (OS) rates of the control, ILA and IPF groups were 76% (95% CI 71% to 83%), 52% (95% CI 37% to 74%) and 32% (95% CI 19% to 53%), respectively (log-rank p<0.001). Patients with ILA had better 5-year OS than those with IPF (log-rank p=0.046) but had worse 5-year OS than those in the control group (log-rank p=0.002). CONCLUSIONS The presence of radiological and pathological features of ILA in patients with lung cancer undergoing curative surgery was associated with frequent complications and decreased survival.

Abstract
Background This study analyzed and described the clinical characteristics and surgical outcomes of diaphragmatic hernia (DH) repair according to the operative approach. Methods After excluding cases with a combined approach and hiatal hernias, we analyzed 26 patients who underwent DH repair between 1994 and 2018. The baseline and perioperative characteristics of the thoracic approach group and the abdominal approach group were described and analyzed. Results Fifteen of the 26 patients were treated through the thoracic approach, including 5 patients who underwent video-assisted thoracic surgery (VATS). Eleven patients underwent the abdominal approach. The thoracic approach was associated with a longer duration of DH than the abdominal approach (2 vs. 0.1 months), herniation of the right-sided abdominal organs, and herniation of the retroperitoneal organs. During the median follow-up of 23 months, there was no recurrence of DH. Conclusion The surgical approach should be chosen considering the duration of DH and the location of herniated organs. VATS might be a safe and feasible option for repairing DH.

Abstract
BACKGROUND The role of adjuvant chemotherapy in esophageal squamous cell carcinoma (ESCC) remains controversial. This study aimed to evaluate the impact of adjuvant chemotherapy on survival in patients with positive nodes after surgery for ESCC. METHODS We retrospectively reviewed the survival outcomes of node-positive patients with ESCC who underwent curative resection with or without adjuvant chemotherapy between January 1994 and December 2015. RESULTS We analyzed 460 patients (333 adjuvant chemotherapy, 127 surgery alone). The surgery-alone group was older (64 vs. 60 years, p < 0.001) and had more comorbidities (p = 0.004) than the adjuvant chemotherapy group. After propensity score matching, overall survival (OS) and recurrence-free survival (RFS) of the adjuvant chemotherapy group were better than those of the surgery-alone group: 5-year OS rate 62.7% (95% confidence interval [CI] 54.4-72.3%) vs. 46.8% (95% CI 38.5-57%, p = 0.001) and 5-year RFS rate 53.9% (95% CI 45.4-63.9%) vs. 36.2% (95% CI 28.3-46.3%, p < 0.001). Notably, in patients with pT3-4 stage, the adjuvant chemotherapy group had significantly better 5-year OS rate (41.3% [95% CI 29.3-58.3%] vs. 18% [95% CI 10-32.5%], p = 0.01) and 5-year RFS rate (37% [95% CI 25.3-53.9%] vs. 12% [95% CI 5.7-25.4%], p < 0.001) than in the surgery-alone group. In multivariable analysis, adjuvant chemotherapy had a favorable effect on both OS (hazard ratio [HR] 0.562, 95% CI 0.426-0.741, p < 0.001) and RFS (HR 0.702, 95% CI 0.514-0.959; p = 0.026). CONCLUSION Adjuvant chemotherapy may improve survival in node-positive patients with ESCC, especially in those with pT3-4 stage.

Abstract
OBJECTIVE Acute low back pain (LBP) is a common condition that can be chronic if not properly treated. Aceclofenac and eperisone hydrochloride are commonly prescribed drugs for acute LBP and muscle spasms. Therefore, NVP-1203, a fixed-dose combination of 100 mg aceclofenac and 75 mg eperisone hydrochloride, is being developed. This study aimed to evaluate the efficacy and safety of NVP-1203 compared to those of a single administration of 100 mg aceclofenac in patients with acute LBP and muscle spasms. PATIENTS AND METHODS Overall, 455 patients with acute LBP and muscle spasms were enrolled. The patients were assigned to NVP-1203 or Airtal group (aceclofenac 100 mg). The primary efficacy endpoint was the mean change in the 100 mm pain movement and resting visual analog scale (VAS) scores on treatment day 7. RESULTS The mean change in the 100 mm pain movement/resting VAS scores from baseline to day 7 was -49.7 ± 21.5/-41.0 ± 19.4 mm and -38.8 ± 18.9/-33.8 ± 18.0 mm for the NVP-1203 and Airtal groups, respectively. The differences between the two groups were statistically significant (movement, p < 0.0001; resting, p = 0.0002). Differences in least-square (LS) mean change of the 100 mm pain movement/resting VAS score between the two groups using the analysis of covariance (ANCOVA) model was -10.2/-7.4 mm, and the upper limit of the 95% confidence interval was -6.44/-4.16 mm. CONCLUSIONS NVP-1203 is more effective in reducing pain than the 100 mg aceclofenac alone. However, the two drugs have similar safety profiles in patients with acute LBP and muscle spasms.

Abstract
PURPOSE This multi-center, retrospective study was conducted to evaluate the long-term survival in patients who underwent surgical resection for small cell lung cancer (SCLC) and to identify the benefit of adjuvant therapy following surgery. MATERIALS AND METHODS The data of 213 patients who underwent surgical resection for SCLC at four institutions were retrospectively reviewed. Patients who received neoadjuvant therapy or an incomplete resection were excluded. RESULTS The mean patient age was 65.29±8.93 years, and 184 patients (86.4%) were male. Lobectomies and pneumonectomies were performed in 173 patients (81.2%), and 198 (93%) underwent systematic mediastinal lymph node dissections. Overall, 170 patients (79.8%) underwent adjuvant chemotherapy, 42 (19.7%) underwent radiotherapy to the mediastinum, and 23 (10.8%) underwent prophylactic cranial irradiation. The median follow-up period was 31.08 months (interquartile range, 13.79 to 64.52 months). The 5-year overall survival (OS) and disease-free survival were 53.4% and 46.9%, respectively. The 5-year OS significantly improved after adjuvant chemotherapy in all patients (57.4% vs. 40.3%, p=0.007), and the survival benefit of adjuvant chemotherapy was significant in patients with negative node pathology (70.8% vs. 39.7%, p=0.004). Adjuvant radiotherapy did not affect the 5-year OS (54.6% vs. 48.5%, p=0.458). Age (hazard ratio [HR], 1.032; p=0.017), node metastasis (HR, 2.190; p < 0.001), and adjuvant chemotherapy (HR, 0.558; p=0.019) were associated with OS. CONCLUSION Adjuvant chemotherapy after surgical resection in patients with SCLC improved the OS, though adjuvant radiotherapy to the mediastinum did not improve the survival or decrease the locoregional recurrence rate.

Mortality and lung function decline in patients who develop chronic pulmonary aspergillosis after lung cancer surgery. BMC Pulm Med 2022; 22:436. [PMID: 36418999 PMCID: PMC9682797 DOI: 10.1186/s12890-022-02253-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 11/18/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Lung cancer surgery is reported as a risk factor for chronic pulmonary aspergillosis (CPA). However, limited data are available on its clinical impact. We aimed to determine the effect of developed CPA after lung cancer surgery on mortality and lung function decline. METHODS We retrospectively identified the development of CPA after lung cancer surgery between 2010 and 2016. The effect of CPA on mortality was evaluated using multivariable Cox proportional hazard analyses. The effect of CPA on lung function decline was evaluated using multiple linear regression analyses. RESULTS During a median follow-up duration of 5.01 (IQR, 3.41-6.70) years in 6777 patients, 93 developed CPA at a median of 3.01 (IQR, 1.60-4.64) years. The development of CPA did not affect mortality in multivariable analysis. However, the decline in forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were greater in patients with CPA than in those without (FVC, - 71.0 [- 272.9 to - 19.4] vs. - 10.9 [- 82.6 to 57.9] mL/year, p < 0.001; FEV1, - 52.9 [- 192.2 to 3.9] vs. - 20.0 [- 72.6 to 28.6] mL/year, p = 0.010). After adjusting for confounding factors, patients with CPA had greater FVC decline (β coefficient, - 103.6; 95% CI - 179.2 to - 27.9; p = 0.007) than those without CPA. However, the FEV1 decline (β coefficient, - 14.4; 95% CI - 72.1 to 43.4; p = 0.626) was not significantly different. CONCLUSION Although the development of CPA after lung cancer surgery did not increase mortality, the impact on restrictive lung function deterioration was profound.
