RESUMEN
The role of surgery in oligometastatic esophageal squamous cell carcinoma (ESCC) remains controversial. This study evaluated the oncological outcomes after esophagectomy in patients with ESCC with distant lymph node (LN) metastasis. Patients with ESCC and nodal metastasis treated with chemoradiotherapy or chemotherapy followed by esophagectomy between 2010 and 2020 were included. Overall survival (OS) and recurrence-free survival (RFS) were compared between patients with distant LN metastasis (dLN+) and exclusively regional LN metastasis (dLN-). The cohort comprised 69 dLN+ and 111 dLN- patients. Survival was significantly better in the dLN- group than in the dLN+ group (5-year OS, 51.9% vs. 25.5%, P < 0.001; RFS, 47.2% vs. 18.1%, P < 0.001). Stratified by the yp stage, 49 (44.1%) dLN- and 30 (43.5%) dLN+ patients achieved a pathological complete response (pCR). In the dLN- and dLN+ groups, the OS rates were significantly higher in the pCR group than in the non-pCR group (dLN-: 76.7% vs. 32.4%, P < 0.001; dLN+: 39.6% vs. 14.2%; P = 0.002). The dLN-/pCR group had the best OS, significantly outperforming the dLN-/non-pCR and dLN+/pCR groups. OS did not differ between the dLN-/non-pCR and dLN+/pCR groups. The dLN+/non-pCR group had the worst OS. The RFS analysis paralleled the OS findings. Patients with dLN+ disease had worse outcomes than their dLN- counterparts, irrespective of the pCR status. The survival rates were poor but comparable between the dLN+/pCR and dLN-/non-pCR groups. Adjuvant therapy may be required for dLN+ patients following systemic treatment and surgery, even after achieving pCR.
RESUMEN
BACKGROUND: Multidisciplinary management strategies are standard in esophageal cancer. Based on a multidisciplinary tumor board (MTB) database in a high-volume center, we aimed to evaluate real-world treatment patterns and patient outcomes in patients with esophageal cancer. In addition, we determined the impact of MTB discussions on patient prognosis. METHODS: Patients diagnosed with esophageal cancer between 2010 and 2019 were retrospectively reviewed. The pattern of treatment modalities and overall survival (OS) of patients with limited, locally advanced, and advanced/metastatic disease were reported. RESULTS: Data from 1132 patients, including 247 patients with limited esophageal cancer, 606 patients with locally advanced esophageal cancer, and 279 patients with advanced/metastatic esophageal cancer were included. Upfront surgery was the most common (56.3%) treatment modality for patients with limited esophageal cancer, while treatment for locally advanced esophageal cancer included upfront surgery (19.1%), neoadjuvant chemoradiotherapy (44.9%), and definitive chemoradiotherapy (36.0%); however, 27.9% of patients undergoing neoadjuvant chemoradiotherapy did not receive planned esophagectomy. Definitive chemoradiotherapy was mainly used for patients with locally advanced and advanced/metastatic disease, but had an incompletion rate of 22.0% and 33.7%, respectively. Regarding survival, the 5-year OS rates were 56.4%, 26.3%, and 5.1% in patients with limited, locally advanced, and advanced/metastatic disease, respectively. Additionally, patients whose clinical management was discussed in the MTB had a significantly better 5-year OS rate than the other patients (27.3% vs. 20.5%, p < 0.001). CONCLUSIONS: We report the real-world data of treatment patterns and patient outcomes in patients with esophageal cancer with respect to multidisciplinary management, and demonstrate the positive impact of MTB discussions on patient prognosis.

BACKGROUND: Recurrent esophageal cancer is associated with dismal prognosis. There is no consensus about the role of surgical treatments in patients with limited recurrences. This study aimed to evaluate the role of surgical resection in patients with resectable recurrences after curative esophagectomy and to identify their prognostic factors. METHODS: We retrospectively reviewed patients with recurrent esophageal cancer after curative esophagectomy between 2004 and 2017 and included those with oligo-recurrence that was amenable for surgical intent. The prognostic factors of overall survival (OS) and post-recurrence survival (PRS), as well as the survival impact of surgical resection, were analyzed. RESULTS: Among 654 patients after curative esophagectomies reviewed, 284 (43.4%) had disease recurrences. The recurrences were found resectable in 63 (9.6%) patients, and 30 (4.6%) patients received surgery. The significant prognostic factors of PRS with poor outcome included mediastinum lymph node (LN) recurrence and pathologic T3 stage. In patients with and without surgical resection for recurrence cancer, the 3-year OS rates were 65.6 and 47.6% (p = 0.108), while the 3-year PRS rates were 42.9 and 23.5% (p = 0.100). In the subgroup analysis, surgery for resectable recurrence, compared with non-surgery, could achieve better PRS for patients without any comorbidities (hazard ratio 0.36, 95% CI: 0.14 to 0.94, p = 0.038). CONCLUSIONS: Mediastinum LN recurrence or pathologic T3 was associated with worse OS and PRS in patients with oligo-recurrences after curative esophagectomies. No definite survival benefit was noted in patients undergoing surgery for resectable recurrence, except in those without comorbidities.

OBJECTIVES: In this study, we examined predictors of exercise adherence, contamination and dropout in lung and oesophageal cancer patients who participated in two randomised controlled trials. METHODS: We used data on 188 lung and oesophageal cancer patients from two previous studies (intervention: moderate-intensity walking for 12 weeks). Baseline measurements included demographic variables, disease characteristics, Hospital Anxiety and Depression Scale and Bouchard 3-day physical activity (PA) record. We used multiple linear and logistic regressions to analyse predictors of exercise adherence in the walking group, contamination in the control group and dropout in both groups. RESULTS: Pre-intervention exercise habits and baseline depression scores predicted adherence, with an explanatory power of 16.7% (p < 0.0001). Pre-intervention exercise habits (odds ratio [OR] 19.65, 95% confidence interval [CI] 2.76-139.97), baseline moderate PA (min/day) (OR 1.03, 95% CI 1.01-1.05) and baseline vigorous PA (min/day) (OR 1.09, 95% CI 1.01-1.18) predicted contamination. Baseline mild PA (10 min/day) (OR 0.94, 95% CI 0.89-0.99) predicted dropout. CONCLUSIONS: Pre-intervention exercise habits and baseline depression levels predicted exercise adherence in the walking group. In the control group, pre-intervention exercise habits and baseline moderate and vigorous PA predicted contamination. Baseline mild PA predicted dropout rates in both groups.

BACKGROUND: Pathologic complete lymph node regression (LNR), where the lymph nodes show evidence of neoadjuvant treatment effect but have no viable residual tumor cells, is sometimes observed following neoadjuvant treatments and has been shown to be prognostic; conflicting results exist in the current literature. METHODS: Patients who received neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy for squamous carcinoma (ESCC) were retrospectively reviewed and classified according to their LNR score; 0: N(-) with no evidence of tumor involvement or regression; 1: N(-) with evidence of complete regression; 2: N(+) with < 50% viable tumor; and 3: N(+) with > 50% viable tumor. RESULTS: In total, 136 patients, comprising 73, 25, 16, and 22 patients with LNR scores of 0, 1, 2, or 3, respectively, were included. Pathologic complete LNR (LNR 1) was significantly associated with lower risks of lymphovascular invasion (0%, p < 0.001) and perineural invasion (4%, p = 0.038), and a higher rate of pathologic complete response in the primary tumor (76%, p < 0.001). The 5-year overall survival rates were 42.1%, 52.8%, and 8.0% in patients with an LNR score of 0, 1, and 2/3, respectively (p < 0.001). There was no significant difference between patients with LNR scores of 0 and 1 in overall survival (p = 0.454), disease-free survival (p = 0.501), and cumulative incidence of recurrences (hazard ratio 0.84, 95% confidence interval 0.432-1.623, p = 0.601). CONCLUSIONS: Pathologic complete LNR could be an indicator of nCRT sensitivity and can be regarded as a good prognostic factor in patients with ESCC. In the survival curve analysis that included patients with lymph node regression (LNR) scores of 0 (blue), 1 (red), and 2/3 (green), we found that patients with pathologic complete LNR (LNR 1), which suggests prior positive nodal involvement, had similar outcomes as those without evidence of prior tumor involvement in lymph node (LNR0).

INTRODUCTION: Few studies have investigated the impact of active surveillance on pathological outcome ground-glass nodules (GGNs). We focused on GGNs that needed preoperative localization before resection and compared the pathological results between GGNs that underwent early resection or active surveillance. METHODS: We retrospectively reviewed data of resected GGNs between January 2017 and December 2018. GGNs were classified by early resection (Group A) and active surveillance (Group B). Group B was subclassified as no (Group B1) and with (Group B2) growth, and intergroup comparison of pathological results was undertaken. RESULTS: In total, 509 GGNs (124, 275, and 110 in Groups A, B1, and B2, respectively) were included. Malignancy (primary lung cancer) ratios were 68% and 72% in Groups A and B (p = .312) and 65% and 92% in Groups B1 and B2, respectively (p < .001). The ratios of invasive carcinoma were 21.4%, 9.6%, and 35.6% in Groups A, B1, and B2, respectively. Predictors for invasive carcinoma included history of lung cancer, GGN size ≥ 10 mm, solid size ≥ 6 mm, and GGN growth. CONCLUSIONS: The pathological findings were similar for GGNs in the early resection and active surveillance groups. However, rates of malignancy and invasive carcinoma increased in the group that manifested growth during active surveillance.

BACKGROUND: The role of extracapsular lymph node involvement (ELNI) in esophageal cancer has not been fully investigated. We aim to assess its incidence and prognostic significance in patients with esophageal squamous cell carcinoma (ESCC) treated with and without neoadjuvant treatments. METHODS: Data of patients who underwent esophagectomy for ESCC in a single medical center was retrospectively reviewed. Patients with positive lymph node involvement were classified as either with ELNI or without ELNI (intracapsular lymph node involvement, ILNI). The impact of ELNI on overall survival (OS), disease-free survival (DFS), and disease recurrence was analyzed. RESULTS: A total of 336 patients, including 179 without (NCRT -) and 157 with (NCRT +) neoadjuvant chemoradiotherapy, were included. Seventy-two of 179 (40.2%) patients in NCRT - group were with positive lymph node, of whom 19 (26.4%) had ELNI, whereas 49 (31.2%) patients in NCRT + group had positive lymph node, of whom 25 (51.0%) had ELNI. In NCRT + group, patients with ELNI had worse outcome compared to those with ILNI in 5-year OS (10.4 vs. 13.8%, p = 0.008), and DFS (5.3 vs. 17.5%, p = 0.008). The presence of ELNI was also associated with more distant recurrence (p = 0.03). In contrast, there was no survival difference between patients with ELNI and ILNI in NCRT - group. CONCLUSIONS: Compared with ILNI, ELNI is a significant poor prognostic factor in patients with ESCC treated with neoadjuvant treatments, but not in those with primary surgery.

PURPOSE: To evaluate whether preoperative biopsy affects the outcomes of patients undergoing at least lobectomy for stage I lung adenocarcinoma. METHODS: We reviewed the medical records of patients who underwent surgery for stage I lung adenocarcinoma between 2006 and 2013. Tumor recurrence and survival were compared between patients who underwent preoperative biopsy, including computed tomographic-guided needle biopsy and transbronchial biopsy, and those who underwent intraoperative frozen section. RESULTS: Among 509 patients, 229 patients (44.9%) underwent preoperative biopsy and 280 patients had lung adenocarcinoma diagnosed by intraoperative frozen section (reference group). Recurrence developed in 65 (12.8%) patients within a median follow-up period of 54.4 months. Multivariate analysis demonstrated that preoperative biopsy (OR 1.97, p = 0.045), radiological solid appearance (OR 5.43, p < 0.001), and angiolymphatic invasion (OR 2.48, p = 0.010) were independent predictors of recurrence. In the overall cohort, preoperative biopsy appeared to worsen 5-year disease-free and overall survival significantly (76.6% vs. 93.0%, p < 0.001; and 83.8% vs. 94.5%, p = 0.002, respectively) compared with the reference group. After propensity matching, multivariable logistic regression still identified preoperative biopsy as an independent predictor of overall recurrence (OR 2.21, p = 0.048) after adjusting for tumor characteristics. CONCLUSION: Preoperative biopsy might be considered a prognosticator of recurrence of stage I adenocarcinoma of the lungs in patients who undergo at least anatomic lobectomy without postoperative adjuvant chemotherapy.

BACKGROUND: Pathological response is an important marker for tumor aggressiveness in patients with esophageal squamous cell carcinoma (ESCC) who receive preoperative chemoradiation followed by esophagectomy. We aim to evaluate the prognostic value of histological factors after trimodality treatments. METHODS: 91 patients who received preoperative chemoradiation followed by transthoracic esophagectomy between 2009 and 2014 were included. The pathological examination was reviewed. Overall survival and disease free survival were recorded. Survival analysis was performed using the Cox regression model, and the survival curves were compared by the log-rank test. RESULTS: Survival analysis showed lymphovascular invasion (LVI, hazard ratio [HR]: 2.009, p = 0.029), perineural invasion (PNI, HR: 2.226, p = 0.019), ypN stage (HR: 2.041, p = 0.019), extracapsular invasion (ECI, HR: 2.804, p = 0.003), and incomplete resection (HR: 1.897, p = 0.039) as unfavorable prognostic factors affecting overall survival (OS). Moreover, tumor regression grade (TRG, HR: 1.834, p = 0.038), LVI (HR: 1.975, p = 0.038), ECI (HR: 2.836, p = 0.003), and incomplete resection (HR: 2.254, p = 0.007) adversely affected disease-free survival (DFS). Prognostic classification based on poor primary tumor (TRG2/3, LVI(+), and PNI (+)), lymph node (ypN(+) and ECI(+)), and surgical (incomplete resection) factors significantly predicts OS (p = 0.013) and DFS (p = 0.017). However, the use of postoperative adjuvant therapy was not a significant prognostic factor even in medium- and high-risk ESCC patients who underwent trimodality treatments. CONCLUSIONS: Histological factors, including primary tumor, lymph node, and surgical factors has high prognostic value for predicting outcomes in ESCC patients receiving preoperative chemoradiation followed by surgery.

BACKGROUND: The role of adjuvant chemoradiation in esophageal cancer has been underestimated in the literature. This study was undertaken to determine whether adjuvant chemoradiation improves survival compared with surgery alone. METHODS: Data of 1095 esophageal squamous cell carcinoma (ESCC) patients, including 679 in surgery alone group (group 1) and 416 in surgery followed adjuvant chemoradaition group (group 2), were obtained from the Taiwan Cancer Registry database. Propensity score matching (PSM) analysis was used to identify 147 well-balanced patients in each group for overall survival comparison. RESULTS: After PSM, the 3-year survival rates and median survival were 44.9% and 27.2 (95% confidence interval [CI]: 17.6-40.3) months in group 2, which is significantly higher than that in group 1 (28.1% and 18.2 [95% CI: 14.3-24.5] months, Pâ=â0.0043). In the multivariate survival analysis, pT3/4 stage (Hazard Ratio [HR]: 2.03, 95% CI: 1.38-2.97, Pâ<â0.001), pN+ stage (HR: 1.83, 95% CI: 1.31-2.57, Pâ=â0.0004), tumor length more than 32âmm (HR: 1.93, 95% CI: 1.33-2.79, Pâ<â0.001), R1/2 resection (HR: 1.75, 95% CI: 1.15-2.66, Pâ=â0.009), and adjuvant chemoradiation (HR: 0.57, 95% CI: 0.42-0.78, Pâ<â0.0001) were independent prognostic factors. Subgroup analysis suggested patients with pT3/4 stage, pN+ stage tumors, larger tumor size, poorly differentiated tumors, and R1/2 resections were more likely to demonstrate survival benefit from adjuvant chemoradiation. CONCLUSIONS: Compared with surgery alone, adjuvant chemoradiation provides a survival benefit to ESCC patients, especially those with pT3/4 stage, N+ tumors, larger tumor size, poorly differentiated tumors, and R1/2 resections.

AIM: In cirrhosis, increased oxidative stress leads to systemic and splanchnic hyperdynamic circulation, splanchnic angiogenesis, portosystemic collateral formation, hepatic endothelial dysfunction, increased intrahepatic resistance and the subsequent portal hypertension. Like N-acetylcysteine, hydrogen-rich saline is a new documented antioxidant with the potential to treat the complications of liver diseases. METHODS: In this study, hemodynamics, splanchnic angiogenesis and hepatic endothelial dysfunction were measured in common bile duct ligation (BDL)-cirrhotic rats receiving 1-month treatment of vehicle, N-acetylcysteine and hydrogen-rich saline immediately after BDL. Additionally, acute effects of N-acetylcysteine and hydrogen-rich saline on vascular endothelial growth factor (VEGF)-induced tubule formation and migration of human umbilical vein endothelial cells (HUVEC) were also evaluated. RESULTS: The data indicate that 1-month treatment of N-acetylcysteine or hydrogen-rich saline significantly ameliorated systemic and splanchnic hyperdynamic circulation, corrected hepatic endothelial dysfunction, and decreased intrahepatic resistance and mesenteric angiogenesis by inhibiting inflammatory cytokines, nitric oxide, VEGF and reducing mesenteric oxidative stress in cirrhotic rats. In vivo studies revealed that acute co-incubation of N-acetylcysteine or hydrogen-rich saline with VEGF effectively suppressed VEGF-induced angiogenesis and migration of HUVEC accompanied by decreasing of oxidative stress and inflammatory cytokines. CONCLUSION: Both hydrogen-rich saline and N-acetylcysteine alleviate portal hypertension, the severity of portosystemic collaterals, mesenteric angiogenesis, hepatic endothelial dysfunction and intrahepatic resistance in cirrhotic rats. N-Acetylcysteine and the new antioxidant, hydrogen-rich saline are potential treatments for the complications of cirrhosis.
RESUMEN
BACKGROUND AND OBJECTIVES: In cirrhosis, hypersensitivity to benzodiazepines (BZD) and precipitating hepatic encephalopathy (HE) have been reported. The aim of this study was to evaluate the safety, economic impact and modifiable factors that are associated with the excess risk of BZD-associated HE in cirrhotic patients. METHODS: Between July 2005 and March 2012, 1,612 Chinese cirrhotic patients with and without using long-t 1/2-BZD or short-t 1/2-BZD were enrolled and followed up for 6 months. RESULTS: Among BZD users, the per-person HE-related healthcare utilization and medical costs were found to have progressively increased from 2005 to 2012. Cirrhotic BZD users had a higher percentage of smoking, alcohol drinking, simultaneous consumption of non-BZD drugs, and had a higher incidence of non-cirrhotic chronic illness than non-BZD users. Multivariate analysis indicated that hypoalbuminemia (<3 g/dL), long-acting (t 1/2 > 12-h), high-dosage (>1.5 defined daily dose equivalents) and long-duration (>2-months) BZD use, carrier of variant genotypes (AG + GG) of GABRA 1 (rs2290732) and having the wild genotype (TT) of GABRG 2 (rs211037) were significant predictors of the development of BZD-associated HE in cirrhotic patients. Additionally, synergistic effects of the above significant predictors on BZD-associated HE risk could be identified. CONCLUSIONS: Our study confirms the clinical and economic impact of BZD-associated HE in cirrhotic BZD-users. Accordingly, extra caution is needed when treating cirrhotic BZD users with the above risk factors in order to avoid the BZD-associated HE in cirrhotic patients.

BACKGROUND: The impact of minimally invasive esophagectomy on patient prognosis, particularly disease-free survival (DFS), has not been well addressed. We compared the clinical outcomes of open and thoracoscopic esophagectomy in patients with esophageal squamous cell carcinoma (ESCC). METHODS: Sixty-three and 66 patients, nonrandomized, underwent open and thoracoscopic esophagectomies for ESCC between 2008 and 2011 were included. The clinicopathological data were reviewed retrospectively. Perioperative outcome, overall survival (OS), DFS, and the recurrence sites after open and thoracoscopic esophagectomy were compared. RESULTS: The open and thoracoscopic groups were comparable with regard to the total number of harvested lymph nodes and the percentage patients undergoing R0 resection. Fewer patients in the thoracoscopic group had pneumonia and wound complications. Intensive care unit (ICU) stay also was shorter in the thoracoscopic group. The recurrence pattern was similar in the two groups. In the open and thoracoscopic groups, the 3-year OS rates were 47.6 and 70.9 % (p = 0.031), respectively, and the 3-year DFS rates were 35 and 62.4 % (p = 0.007), respectively. However, the trends in better OS and DFS in the thoracoscopic group were not significant after stratification according to pathologic stage. CONCLUSIONS: The perioperative benefit of thoracoscopic esophagectomy included fewer postoperative complications and shorter ICU stays. Mid-term OS and DFS associated with thoracoscopic techniques are at least equivalent to those associated with open procedures.

BACKGROUND: Chylothorax is an infrequent but well-known complication in lung cancer surgery. Previous published studies on this topic are limited, and thoracotomy has been the main surgical approach for treatment. However, chylothorax after lung cancer surgery performed solely by video-assisted thoracoscopic surgery (VATS) has rarely been investigated. The purpose of this study is to evaluate chylothorax after VATS for lung cancer. METHODS: The records of 776 patients with primary non-small-cell lung cancer (NSCLC) who underwent VATS for pulmonary resection and mediastinal lymph node dissection (MLND) at our hospital from January 2010 to August 2013 were retrospectively reviewed. Twenty patients with chylothorax (2.58 %) were included in the analysis. RESULTS: The 20 patients with chylothorax were all treated conservatively, but five patients (25 %) subsequently required reoperation for chylothorax. In patients with pleural drainage of less than 400 ml the first postoperative day, the chylothorax resolved with conservative treatment. Chylothorax also resolved in patients with pleural drainage of more than 400 ml the first or second postoperative day if drainage was less than 400 ml on postoperative day 4 and thereafter. Reoperations were required in cases with an increasing amount of pleural drainage on postoperative day 4 and thereafter. CONCLUSIONS: Most of the chylothorax following VATS for lung cancer can be treated conservatively. However, the timing of surgical intervention for chylothorax following VATS for lung cancer can be earlier if pleural drainage does not show a trend toward decreasing with conservative treatment.

PURPOSE: Percutaneous tracheostomy (PT) has gained worldwide acceptance as a bedside procedure by intensivists, but its popularity has declined based on reports of some relative contraindications. The aim of this study was to ascertain the perioperative comorbidities of PT when it is performed by surgeons with experience performing standard tracheostomy. METHODS: Prospective data were collected and analyzed for consecutive PTs performed in intensive care units. RESULTS: No procedure-related mortality occurred in the present study. No significant differences in perioperative comorbidities, such as transient hemodynamic instability and postoperative wound infection, were noted between the relative contraindication (RC) and normal condition (NC) groups. Otherwise, instrument failure (5 cases, p = 0.052) and procedure failure (2 cases, p = 0.222) occurred in the RC group, but not in the NC group. Two patients in the NC group and one patient in the RC group needed to undergo a reoperation to check for bleeding. In a subgroup analysis, more bleeding events were noted for the patients with coagulopathy (p = 0.057), and premature extubation of the endotracheal tube/instrument failure (p = 0.073) was more common in the patients with neck anatomical difficulty in the RC group. CONCLUSIONS: For patients with relative contraindications, the potential of using PT should be determined on an individual basis. Special attention should be paid to the possibility of instrument failure and bleeding events for the patients with relative contraindications for PT.

OBJECTIVES: To examine the moderating effect of daylight exposure on physical activity and objective sleep quality, using wearable actigraph devices. METHODS: We recruited 324 patients with either gastric or esophageal cancer. Actigraphs were used to measure all objective data including daylight exposure, physical activity, and sleep quality. Pearson's correlation coefficients were used to examine the relationships among demographic data, disease attributes, physical activity, daylight exposure, and sleep. The Hayes PROCESS macro with the regression bootstrapping method was employed to analyze the moderating effect of daylight exposure on the relationship between physical activity and sleep. RESULTS: Sleep efficiency correlated positively with physical activity, while "wake after sleep onset" correlated negatively with physical activity and mean lux. Mean lux and light >500 lux significantly moderated the association between physical activity and sleep efficiency (Pâ¯=â¯.002 in both cases). Similarly, mean lux and light >500 lux significantly moderated the association between physical activity and "wake after sleep onset" (Pâ¯=â¯.002 and .001, respectively). CONCLUSION: Both average daylight exposure and time of exposure to >500 lux act as moderators of physical activity and objective sleep quality in patients with gastric or esophageal cancer. Healthcare practitioners should encourage patients with cancer to engage in daily outdoor physical activity. Further intervention studies are needed to verify the combined effect of daytime light exposure and physical activity on improving sleep quality. IMPLICATIONS FOR NURSING PRACTICE: Healthcare practitioners should encourage patients with cancer to engage in daily outdoor physical activity. Further intervention studies are needed to verify the combined effect of daytime light exposure and physical activity on improving sleep quality.

BACKGROUND: Although rest-activity circadian rhythm (RACR) disruption is associated with mortality in patients with cancer, few studies have examined the effect of RACR on patients with esophageal and gastric cancer. OBJECTIVE: The aim of this study was to identify the predictors of RACR. METHODS: This cross-sectional, single-site study included 276 patients with esophageal and gastric cancer recruited from chest-surgery and general-surgery outpatient departments. Actigraphy was used to assess objective physical activity (PA), daylight exposure, and RACR, and 3-day PA was used to indicate the subjective amount of PA. The parameter of objective PA was the up activity mean; the parameter of daylight exposure was >500 lx, and the parameters of RACR were the 24-hour correlation coefficient, in-bed less than out-of-bed dichotomy index, midline estimating statistic of rhythm, and amplitude. The subjective amount of PA was calculated as the sum of mild, moderate, and vigorous PA. RESULTS: The up activity mean predicted 24-hour correlation coefficient. The PA amount and up activity mean predicted in-bed less than out-of-bed dichotomy index. The up activity mean and >500-lx daylight exposure predicted midline estimating statistic of rhythm. Finally, the PA amount and up activity mean predicted the amplitude. CONCLUSIONS: Increased PA and daylight exposure may improve RACR. IMPLICATIONS FOR PRACTICE: Patients with esophageal and gastric cancer should be encouraged to engage in outdoor PA during the daytime as part of their regular lifestyle to maintain a robust circadian rhythm.

BACKGROUND: The standard treatment for pathological N2 (pN2) non-small-cell lung cancer (NSCLC) patients is definitive chemoradiation. Surgery might be beneficial for resectable pN2 disease, so we investigated the recurrence-free interval of upfront surgery for selected patients with resectable pN2 disease. METHODS: The clinicopathologic characteristics of patients with pN2 NSCLC who underwent upfront anatomical resection at Taipei Veterans General Hospital from 2011 January to 2019 December were retrospectively reviewed. A Cox regression model was used to identify prognostic factors of recurrence-free survival (RFS). RESULTS: In total, 84 patients after curative lung anatomic resection were analyzed, with a 44-month median survival. The 1-, 3-, and 5-year RFS rates were 63.1%, 31.3%, and 19.9%, respectively, with a median RFS of 18.9 months. Multivariable cox regression analysis identified that the significant predictor for RFS was a tumor size of more than 3 cm (hazard ratio [HR] = 1.74, 95% CI, 1.07-2.83, p = 0.027). Visceral pleural invasion, LN harvest number, tumor stage, and N2 status including single zone (N2a) or multiple zones (N2b) were not prognostic factors in this study. CONCLUSION: Upfront surgery for resectable N2 disease achieved favorable outcomes in selected patients, especially better recurrence control with limited tumor size. Therapeutic advances might encourage surgeons to aggressive intervention.

BACKGROUD: The standard resection for early-stage thymoma is total thymectomy and complete tumour excision with or without myasthenia gravis but the optimal surgery mode for patients with early-stage non-myasthenic thymoma is debatable. This study analysed the oncological outcomes for non-myasthenic patients with early-stage thymoma treated by thymectomy or limited resection in the long term. METHODS: Patients who had resections of thymic neoplasms at Taipei Veteran General Hospital, Taiwan between December 1997 and March 2013 were recruited, exclusive of those combined clinical evidence of myasthenia gravis were reviewed. A total of 113 patients were retrospectively reviewed with pathologic early stage (Masaoka stage I and II) thymoma who underwent limited resection or extended thymectomy to compare their long-term oncologic and surgical outcomes. RESULTS: The median observation time was 134.1 months [interquartile range (IQR) 90.7-176.1 months]. In our cohort, 52 patients underwent extended thymectomy and 61 patients underwent limited resection. Shorter duration of surgery (p < 0.001) and length of stay (p = 0.006) were demonstrated in limited resection group. Six patients experienced thymoma recurrence, two of which had combined myasthenia gravis development after recurrence. There was no significant difference (p = 0.851) in freedom-from-recurrence, with similar 10-year freedom-from-recurrence rates between the limited resection group (96.2 %) and the thymectomy group (93.2 %). Tumour-related survival was also not significantly different between groups (p = 0.726).result CONCLUSION: Patients with early-stage non-myasthenic thymoma who underwent limited resection without complete excision of the thymus achieved similar oncologic outcomes during the long-term follow-up and better peri-operative results compared to those who underwent thymectomy.

OBJECTIVES: This study evaluates the prognostic impact of the new grading system for lung adenocarcinoma, stratified by lymphadenectomy extent. MATERIALS AND METHODS: We analyzed 1258 lung adenocarcinoma patients who underwent curative resections between 2006 and 2017. We analyzed overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) across tumor grades and lymphadenectomy extent, categorized as IASLC-R0 (complete resection) or R(un) (uncertain resection). RESULTS: The median age of cohort was 63 and 41.9 % were male. The majority had undergone lobectomy. The distribution of tumors was 274 grade 1, 558 grade 2, and 426 grade 3 cases. After a median follow-up time of 102 months, the 10-year OS/CSS/RFS rates worsened significantly across grade 1-3: 92.4/99.3/92.3 %, 77.8/87.5/71.7 %, and 63.6/70.2/52.0 %, respectively (p < 0.001). Multivariate Cox regression analysis identified grade 3, R(un) lymphadenectomy, higher Charlson Comorbidity Index, smoking history, thoracotomy, higher pathology stage, and angiolymphatic invasion as independent prognostic factors for lower OS, CSS, and RFS. Furthermore, grade 3 patients benefited significantly from IASLC-R0 lymphadenectomy, showing significantly better OS and RFS than those who underwent R(un) lymphadenectomy (p = 0.007 for OS, p = 0.001 for RFS, post-propensity score matching). Among grade 3 tumors underwent R0 or R(un) resections found the incidence rates of local, distant, and simultaneous local and distant recurrence were 8.5 % vs 13.7 %, 11.0 % vs 12.2 %, and 11.0 % vs 20.6 %, respectively. CONCLUSION: Surgical outcomes for lung adenocarcinoma have declined across grades 1-3. IASLC-R(un) treatment worsens OS and RFS in grade 3. Intensive monitoring and adjuvant therapy should be considered when patients with grade 3 lung adenocarcinoma undergo R(un) lymphadenectomy.
