Sequential multimodal treatments with chemotherapy and surgery for advanced soft tissue sarcoma may be associated with better survival than chemotherapy.

BACKGROUND: In patients with advanced soft tissue sarcoma (STS), surgery had been reported to be associated with superior overall survival (OS). Chemotherapy details for such patients were less reported, and whether multimodal treatment with surgery and chemotherapy provides extra survival benefit remains unclear. METHODS: We retrospectively reviewed patients with newly diagnosed advanced STS treated at National Taiwan University Hospital from January 1, 2011, to December 31, 2017. OS was calculated from the day of diagnosis of advanced STS to the day of death or last follow-up. Baseline patient characteristics and details regarding surgery and chemotherapy were recorded. RESULTS: A total of 545 patients were diagnosed with STS from 2011 to 2017, of which 226 patients had advanced STS. The median age was 54.7 years, and 54% of patients were women. Approximately 38% of patients with advanced STS underwent surgery and exhibited a trend of longer OS compared with who did not (median = 18.6 vs. 11.9 months, p = 0.083). In the chemotherapy subgroup, the benefit of surgery was more prominent (median = 21.9 vs. 16.5 months, p = 0.037). Patients who received chemotherapy prior to surgery exhibited numerically longer OS than those who underwent surgery first (median = 33.9 vs. 18.3 months, p = 0.155). After adjusting other clinical factors, chemotherapy remained an independent factor associated with favourable OS. CONCLUSION: Surgery may be more beneficial for the patients who receive chemotherapy. Our results support evaluation of sequential multimodal treatments strategy including surgery and chemotherapy in patients with advanced STS.

Stripping Massage and Literature Review in Post-Thoracoscopic Chest Pain Management.

The aim of this randomized study was to investigate whether stripping massage (SM) of myofascial trigger points in the lower rhomboid muscle could alleviate chest pain in patients following thoracoscopic surgery. In addition, a literature review was conducted to assess the effectiveness of various pain management techniques. Sixty adult patients who reported a visual analog scale (VAS) score of 4 or higher were randomly assigned to receive conventional analgesics alone (conventional group) or combined with SM twice daily for 2 weeks (SM group). VAS scores and the use of additional analgesics were evaluated on postoperative days 1, 3, 7, 14, and 30. Using the PubMed and Cochrane Library databases, a review of current pain management techniques was carried out up to January 31, 2022. A subgroup analysis was also performed to examine the treatment effect during different surgical periods and techniques. Results showed that the SM group had significantly lower VAS scores on postoperative days 3, 7, 14, and 30 (p < 0.001), as well as a shorter hospitalization duration and reduced need for additional analgesics (p < 0.001). The literature review included a total of 20 studies (2,342 cases of chest pain relief after thoracoscopic surgery), which indicated that serratus anterior plane (SAP) blocks were commonly used as a perioperative approach to reduce pain and opioid consumption. SM and SAP can both serve as adjuvant treatments for chest pain in patients following thoracoscopic surgery, with SM being a safe and noninvasive pain control option after hospital discharge.

The management of postoperative upper alimentary tract fistulas: A single-center experience of endoscopic tissue glue repair and recommendations of a systematic review.

BACKGROUND/PURPOSE: The appropriate management of postoperative upper alimentary tract fistula (UATF) remains uncertain. The efficacy of esophagogastroduodenoscopy (EGD) tissue glue repair in the treatment of patients with postoperative UATF was explored. We also conducted a systematic review of the literature regarding the inpatient management of UATF. METHODS: Totally 24 patients received EGD tissue glue repair for postoperative UATF at our institute from April 2014 to April 2020. Independent characteristics of size of fistula, location of the UATF, complications, and recurrences were analyzed. PubMed and Cochrane Library databases were reviewed. A pooled analysis was performed, and subgroup analysis was conducted separately for different anatomic locations and techniques. RESULTS: With a mean follow-up of 40 months, the fistula failed to close with EGD tissue glue repair in 2 of 24 patients (8.3%). Eight patients required repeated EGD tissue glue repair, which was more frequent in oral or thoracic UATF (p = 0.053), but all achieved a successful seal in the EGD tissue after glue repair alone (n = 22). The fistula size was correlated with the demand for repeated EGD tissue glue repair (p = 0.017). Besides, a total of 30 studies regarding 2356 cases of postoperative UATF between 2010 and 2021 were retrieved and analyzed. Several non-operative methods were generally accepted as the initial approach, with a non-inferior success rate compared to operative techniques. CONCLUSION: The results suggest that no single approach toward UATF is superior in terms of success rate and healing time. The potential advantages of EGD tissue glue repair after drainage were more suitable for patients with postoperative UATF and multiple comorbidities.

Comparison of perioperative outcomes between intubated and nonintubated thoracoscopic surgery in children.

BACKGROUND/PURPOSE: This study aimed to compare our experiences of nonintubated video-assisted thoracoscopic surgery (VATS) for pneumothorax and lung tumor resections with that of intubated VATS in pediatric patients. METHODS: In total, 17 nonintubated and 64 intubated pediatric VATS were performed between January 2012 and December 2018. Patient characteristics, operation period, comorbidities, precedent lung surgery, diagnosis, type of anesthesia, side and type of procedure, and perioperative outcomes were collected from medical records. Perioperative outcome data included induction time, operation time, postoperative chest tube drainage duration, and length of stay. Simple linear regression and multiple linear regression analyses were used to determine the influence of selected variables on perioperative outcomes. RESULTS: The mean age was 16.2 years in the intubated group and 15.2 years in the nonintubated group. Comorbidities including malignancy and asthma were noted in 9 intubated patients and 6 nonintubated patients. Nonintubated VATS was performed in 9 pneumothorax surgeries and 8 lung tumor resections. Five patients breathed oxygen through a face mask, 3 patients through a high-flow nasal cannula, and 9 patients through a laryngeal mask airway. No patient required tracheal intubation or thoracotomy. No major operative complications were noted in either group. After adjustments for statistically relevant confounders, the multiple regression analysis showed that the nonintubated technique influenced the length of stay, leading to a reduction of 0.75 days. CONCLUSION: Nonintubated VATS is feasible and safe in selected children undergoing bullectomy or wedge resections for lung tumors. The nonintubated approach might enhance postoperative recovery.

The Long-Term Clinical Impact of Thoracic Endovascular Aortic Repair (TEVAR) for Advanced Esophageal Cancer Invading Aorta.

BACKGROUND: Advanced esophageal cancer invading the aorta is considered unsuitable for surgery with definitive chemotherapy or chemoradiation as the treatments of choice. In the current study, we evaluated the long-term clinical impact of combining thoracic endovascular aortic repair (TEVAR) with multimodality treatment in caring for such patients. METHODS: We evaluated 48 patients who had advanced esophageal cancer with aortic invasion. The oncological outcome, including overall survival (OS) and progression-free survival (PFS), after multimodality treatment with or without TEVAR is evaluated for these patients. RESULTS: Overall, 25/48 patients (52.1%) received a TEVAR procedure. There was no significant difference in OS (p = 0.223) between patients who did or did not receive TEVAR; however, patients who received TEVAR had significantly less local tumor recurrence (p = 0.020) and longer PFS (p = 0.019). This impact was most evident in patients who received both TEVAR and esophagectomy, with an incremental increase in hazard ratio (HR) for disease progression of 2.89 (95% confidence interval [CI] 0.86-9.96) and 4.37 (95% CI 1.33-14.33) observed under multivariable analysis, respectively, in comparison with patients who underwent only one or neither of these procedures (p = 0.005 for trend test). CONCLUSION: TEVAR is a feasible procedure for esophageal cancers invading the aorta and can be used for curative-intent resection to improve local tumor control and PFS.

Augmented fluoroscopic bronchoscopy (AFB) versus percutaneous computed tomography-guided dye localization for thoracoscopic resection of small lung nodules: a propensity-matched study.

BACKGROUND: Dye localization is a useful method for the resection of unidentifiable small pulmonary lesions. This study compares the transbronchial route with augmented fluoroscopic bronchoscopy (AFB) and conventional transthoracic CT-guided methods for preoperative dye localization in thoracoscopic surgery. METHODS: Between April 2015 and March 2019, a total of 231 patients with small pulmonary lesions who received preoperative dye localization via AFB or percutaneous CT-guided technique were enrolled in the study. A propensity-matched analysis, incorporating preoperative variables, was used to compare localization and surgical outcomes between the two groups. RESULTS: After matching, a total of 90 patients in the AFB group (N = 30) and CT-guided group (N = 60) were selected for analysis. No significant difference was noted in the demographic data between both the groups. Dye localization was successfully performed in 29 patients (96.7%) and 57 patients (95%) with AFB and CT-guided method, respectively. The localization duration (24.1 ± 8.3 vs. 21.4 ± 12.5 min, p = 0.297) and equivalent dose of radiation exposure (3.1 ± 1.5 vs. 2.5 ± 2.0 mSv, p = 0.130) were comparable in both the groups. No major procedure-related complications occurred in either group; however, a higher rate of pneumothorax (0 vs. 16.7%, p = 0.029) and focal intrapulmonary hemorrhage (3.3 vs. 26.7%, p = 0.008) was noted in the CT-guided group. CONCLUSION: AFB dye marking is an effective alternative for the preoperative localization of small pulmonary lesions, with a lower risk of procedure-related complications than the conventional CT-guided method.

Recent advances and controversies in surgical intervention of nontuberculous mycobacterial lung disease: A literature review.

The prevalence of nontuberculous mycobacterial lung disease (NTM-LD) has increased in Western and Asian nations in recent decades. While surgery may improve the outcome of more complex cases, many inconsistencies exist in the current literature regarding the management, growing emergence, and challenges of drug-resistant forms of NTM-LD, the indications and timing of surgical treatment, and perioperative multimodal therapy of NTM-LD. Moreover, data regarding the comparative treatments, risk factors of pulmonary resection for NTM-LD, and the long-term outcomes of microbiological recurrence are limited. This review will focus on outlining the outcomes of recently optimized surgical approaches, as well as providing an overview of the roles of perioperative multimodalities therapies in the treatment of NTM-LD.

Phase II study of metabolic response to one-cycle chemotherapy in patients with locally advanced esophageal squamous cell carcinoma.

BACKGROUND: In the treatment of esophageal squamous cell carcinoma (ESCC), the optimal use of 18fluorodeoxyglucose positron emission tomography (PET) in measuring metabolic tumor response is undetermined. We launched a phase II trial to evaluate early metabolic response to one-cycle induction chemotherapy in patients with locally advanced ESCC. METHODS: ESCC patients in stage classification T3N0, N1M0, or M1a (American Joint Committee on Cancer, 6th edition) received one-cycle chemotherapy comprising paclitaxel, cisplatin, and 24-h infusional 5-fluorouracil and leucovorin on days 1 and 8, followed by neoadjuvant chemoradiotherapy, 40 Gy, with paclitaxel/cisplatin and then esophagectomy. PET was performed at baseline and day 14 of chemotherapy. The primary endpoint was pathologic complete response (pCR). We hypothesized early metabolic responders with >35% reduction in maximum standardized uptake value (SUVmax), would have better pCR Results. RESULTS: Sixty-six patients were enrolled. The median progression-free survival (PFS) and overall survival (OS) were 16 months (95% confidence interval [CI], 9-27) and 22 months (16-40), respectively. The early metabolic response rate was 55%; and the pCR rate was 34% in the esophagectomy population. The early metabolic response was not associated with pCR or survival. In an exploratory analysis, the postchemotherapy SUVmax was an independent prognostic factor for pCR, PFS, and OS. CONCLUSION: Our study failed to validate the predefined early metabolic response for pCR to neoadjuvant chemoradiotherapy in locally advanced ESCC patients. However, postchemotherapy SUVmax may be prognostic and predictive, and warrants further study.

Circulating Interleukin-6 is Associated with Prognosis and Genetic Polymorphisms of MIR608 in Patients with Esophageal Squamous Cell Carcinoma.

BACKGROUND: No effective targeted therapy exists for esophageal squamous cell carcinoma (ESCC), the major cell type of esophageal cancer. The pleiotropic cytokine interleukin (IL)-6 is associated with adverse prognosis of some cancers, and the open reading frame of IL-6 contains an miR-608 microRNA-targeted site. We investigated the correlation of circulating IL-6 levels with prognosis and with the mir608:rs4919510 genetic polymorphism in ESCC. METHODS: A total of 213 patients with primary ESCC were enrolled. Plasma IL-6 levels of ESCC patients were analyzed by enzyme-linked immunosorbent assay (ELISA). The patients' genotypes of mir608:rs4919510 were analyzed using the MassARRAY system, and functional assays were performed by transient overexpression in cells. The cytotoxicity of IL-6 signaling blockers in ESCC cells was analyzed by MTT assay. RESULTS: We found that plasma IL-6 levels significantly correlated with overall survival (p = 0.019), disease recurrence (p = 0.003), and postoperative complications (p =0.002). Patients with the GG genotype of mir608:rs4919510 had a 4.56-fold increased risk of high expression of IL-6 compared with patients with the CC genotype (odds ratio 4.56, 95% confidence interval 1.87-11.09; p =0.001). Transient overexpression of the miR-608 C (miR-608_C) and G variants (miR-608_G) in cancer cells revealed that the miR-608_G variant was less efficient in regulating the expression of IL-6 compared with miR-608_C. Finally, the IL-6 signaling blocker ruxolitinib exhibited effective cytotoxicity in ESCC cells. CONCLUSIONS: The results of this study provide a novel direction for a biomarker-based targeted therapy for ESCC.

Do We Need to Add Postoperative Radiotherapy in Patients Undergoing Trimodality Therapy for Esophageal Squamous Cell Carcinoma with Positive Lymph Nodes Disease?

BACKGROUND: The role of adjuvant radiotherapy for positive lymph nodes (LN) in patients with esophageal cancer who received neoadjuvant concurrent chemoradiotherapy (CCRT) is not well established. This study is aimed at determining the impact of positive LN and the survival benefit of postoperative radiotherapy (PORT) after CCRT plus surgery on esophageal cancer patients. METHODS: Seventy patients with positive LN after neoadjuvant CCRT followed by esophagectomy were enrolled in the study. Patients were grouped into surgery alone following neoadjuvant CCRT (n = 41) and surgery plus PORT following neoadjuvant CCRT (n = 29) groups. The preoperative radiation dose was 36-45 Gy (mean 40 Gy) and the postoperative radiation dose was 20 Gy in 10 fractions. RESULTS: The 5-year survival rate and mean survival was 40% and 58.6 ± 53.9 months for patients with a pathologic complete response (pCR) compared with 8.3% and 22.7 ± 35.5 months, respectively, for non-pCR patients (p = 0.026). Local and distant recurrent patterns were similar for patients who did and did not receive PORT (p = 0.876). The mean survival did not differ significantly between the 2 groups (p = 0.889). Pathological complete response to CCRT was the only significant factor influencing survival (p = 0.026). CONCLUSIONS: Postoperative RT did not improve survival in patients with positive LN after CCRT followed by curative surgery for esophageal cancer.

Early Postoperative Endoscopy for Evaluation of the Anastomosis after Esophageal Reconstruction.

BACKGROUND: Anastomotic leaks significantly affect hospital stay after esophageal surgery. Here, we investigated the efficacy of early endoscopy for predicting anastomotic healing and leaks after esophageal reconstruction. METHODS: A total of 65 consecutive esophageal cancer patients treated by cervical esophagogastrostomy underwent routine endoscopy between postoperative days 5 and 7. The anastomosis was scored for the degree of ischemia, stenosis, and torsion of the anastomotic axis. Independent associations between ischemia, stenosis, and torsion of the proximal esophagus and the risk of the anastomotic leak were examined using Spearman's rank correlation method. RESULTS: Assessment of the degree of mucosal ischemia in 65 patients shows well healing in 35, patch ischemia in 20, diffuse ischemia in 10, no necrosis in any patient. Stenosis was classified as 0 to 10% in 40 patients, 11 to 20% in 12, 21 to 80% in 11, and 81 to 100% in 2. The degree of torsion of the anastomotic axis was classified as 0 to 10 degrees in 52 patients, 11 to 90 degrees in 8, and 91 to 180 degrees in 5. With rising endoscopy scores, there was an increase in risk for leaks (score > 4.5, sensitivity 100%, and specificity 83.8%). CONCLUSIONS: Early postoperative endoscopy facilitates the management of esophagogastrostomy anastomosis to predict leaks.

Are single or dual luminal covered expandable metallic stents suitable for esophageal squamous cell carcinoma with esophago-airway fistula?

BACKGROUND: To analyze the outcomes of single or dual luminal self-expandable covered metallic stents (SECMS) for palliative treatment for esophageal cancer with esophago-airway fistula (EAF). METHODS: We retrospectively assessed 50 patients who underwent SECMS placement for malignant EAF at our institution between June 2005 and December 2014 to define clinical results of stenting. Treatment provided was classified into initial single airway, single esophageal, or double stent placement. Independent associations between size, location of the EAF, patient's condition, and the risk of migration or reopening with the different types of stenting were examined using logistic regression analysis. RESULTS: The final management of malignant EAF was esophageal stent in 21 patients, airway stent in 13, and dual stents in 16. No patients failed stenting. During a median follow-up of 178 days (range 1-893 days), the fistula reopened in 33 (66 %) of 50 patients. No factors, including fistula size, location, or initial selection of single or dual stenting, were correlated with reopening. Nineteen (57.6 %) of 33 patients needed restenting, and the reopened EAF was sealed off successfully in 52.6 % of new stent placements. The clinical failure of EAF closure was correlated only with proximal dilated esophagus (p = 0.013). Mean survival in patients with clinical success of EAF closure was also significantly longer than that in patients with clinical failure (242.0 vs. 80.1 days, p < 0.001). KPS (p = 0.026), cough ability (p = 0.004), successful closure of EAF (p = 0.001), and reopening (p = 0.007) all had significant effects on survival. CONCLUSIONS: We conclude that SECMS is safe and effective in the palliation of esophageal cancer with malignant EAF, especially in patients with an otherwise excellent general condition. Other modalities of management are recommended for malignant EAF with proximal dilation of the esophagus.

Comparison of single- and multi-incision minimally invasive esophagectomy (MIE) for treating esophageal cancer: a propensity-matched study.

OBJECTIVE: To compare the perioperative outcome of minimally invasive (MIE) esophagectomy performed with a single- or a multi-incision in treating esophageal cancer. METHOD: Patients with esophageal cancer who underwent MIE from 2006 to 2016 were evaluated. A 3-4-cm incision was created in both the thoracoscopic and the laparoscopic phases during the single-incision MIE procedures. A propensity-matched comparison was made between the two groups of patients. RESULTS: We analyzed a total of 48 pairs of patients with propensity-matched from the cohort of 360 patients undergoing MIE during 2006-2015. There is no statistical difference in terms of postoperative ICU and hospital stay, number of dissected lymph nodes and presence of major surgical complications (anastomotic leakage and pulmonary complications) between the two groups of patients. The pain score one week after surgery was significantly lower in the single-incision group (p < 0.05). There was no surgical mortality in the single-incision MIE group. CONCLUSION: Minimally invasive esophagectomy performed with a single-incision approach is feasible for treating patients with esophageal cancer, with a comparable perioperative outcome with that of multi-incision approaches. The postoperative pain one week after surgery was significantly reduced in patients undergoing single-incision MIE.

Laparoscopic percutaneous jejunostomy with intracorporeal V-Loc jejunopexy in esophageal cancer.

BACKGROUND: Barbed sutures are widely used in various laparoscopic digestive surgeries. The purpose of this paper is to present our initial experience of laparoscopic percutaneous jejunostomy with unidirectional barbed sutures in esophageal cancer patients and compare it with our early cases using traditional transabdominal sutures. METHODS: A total of 118 esophageal cancer patients who underwent laparoscopic percutaneous jejunostomy were identified in a single institution in Taiwan from June 2014 to May 2016. The authors' traditional technique consisted of using transabdominal sutures with bolsters to fix a jejunum loop onto the anterior abdominal wall. A novel technique was introduced using intracorporeal suturing with knotless unidirectional barbed monofilament absorbable sutures (V-Loc) to attain a seal around the feeding catheter. A comparison between these two techniques was performed. RESULTS: Twenty cases with barbed V-Loc sutures and 98 cases with transabdominal sutures were identified. The V-Loc sutures appeared to reduce peristomal skin ulcers (19.4 vs. 0 %, p = 0.040), postoperative pain scores during the first 24 h (1.8 ± 1.4 vs. 0.9 ± 1.1, p = 0.007) and on postoperative day 2 (1.7 ± 1.4 vs. 1.0 ± 0.8, p = 0.026) when compared to patients receiving transabdominal sutures. The mean suturing time using V-Loc sutures was 22 min (14-60 min). The mean onset to resumption of enteral feeding was 1.8 ± 0.8 days and the mean duration of postoperative hospital stay was 8 ± 5.1 days, both of which were comparable in the two groups. There was no surgical mortality in our series. CONCLUSIONS: In the study cohort, the use of knotless unidirectional barbed sutures instead of traditional transabdominal sutures had similar outcomes and appears to be a feasible option for intracorporeal jejunopexy when performing laparoscopic jejunostomy in patients with esophageal cancer.

Twenty-years of lung transplantation in Taiwan: Effects of cumulative institutional experience on early outcomes.

BACKGROUND/PURPOSE: Lung transplantation in Taiwan began in 1991, but the experience was limited and diverse in the early years. We examined the cumulative institutional experience of the largest lung transplant cohort in Taiwan. METHODS: A retrospective review of lung transplantations performed at a single institution from December 1995 through August 2016 was conducted. For comparative purposes, the cohort was divided into halves, with an early group (undergoing lung transplantation in the first decade) vs a late group (undergoing lung transplantation in the second decade). Standardized donor selection, organ procurement, and preservation protocols for brain-dead donors were applied. The outcomes measured were 30-day mortality and actuarial survival using the Kaplan-Meier method. RESULTS: The cohort included 50 recipients in the early group and 42 recipients in the late group. Compared with the early group, recipients in the late group were significantly older (38.8 ± 11.6 vs 44.8 ± 13.4 years, p = 0.024) and more of them required mechanical ventilation before transplant (26.0% vs 66.7%, p < 0.001). There were more female donors (12.0% vs 33.3%, p = 0.021) and gender-matched donors (34.0% vs 61.9%, p = 0.012) in the late group. A total of 87 recipients (94.6%) had cardiopulmonary bypass (CPB) or extracorporeal membrane oxygenation (ECMO) support during transplant, and CPB was used significantly less in the late group. Graft procedures (14.0% vs 47.6%, p < 0.001), delayed chest closure (0% vs 21.4%, p < 0.001), and early tracheostomy (24.0% vs 52.4%, p = 0.005) were performed more in the late group. The durations of hospital and ICU stays were comparable in both groups, but the 30-day mortality was significantly lower in the late group (30.0% vs 2.4%, p = 0.001). CONCLUSION: Although the results were undesirable in the first decade of the transplant program, the cumulative institutional experience led to significantly improved outcomes in the second decade of the transplant program.

Intrapleural Epinephrine Irrigation for Massive Malignant Hemothorax.

Massive malignant hemothorax (MMH) is a rare and serious complication encountered in the field of oncology and can be life threatening. It is often difficult and complex to manage. Herein, we present cases of four patients who had MMH and in whom a hemothorax was successfully stopped via continuous intrapleural irrigation with epinephrine (5-mg epinephrine/1,000-mL normal saline, infused at 100 mL/h) instead of a conventional surgical approach. Although no patient deaths were attributed to intractable bleeding, two deaths were related to multiple organ failure. Despite the limited number of cases, this method was a convenient, effective, and inexpensive alternative to open surgical or thoracoscopic drainage for MMH.

A Walk-and-Eat Intervention Improves Outcomes for Patients With Esophageal Cancer Undergoing Neoadjuvant Chemoradiotherapy.

BACKGROUND: Preserving functional walking capacity and nutritional status is important for patients with esophageal cancer, but no effective intervention is available, particularly during active treatment. METHODS: This pilot randomized controlled trial tested the effects of a walk-and-eat intervention for patients with esophageal cancer undergoing neoadjuvant chemoradiotherapy. Participants with locally advanced esophageal cancer stage IIB or higher (n = 59) were randomly assigned to receive the walk-and-eat intervention (n = 30; nurse-supervised walking three times per week and weekly nutritional advice) or usual care (n = 29; control group) during 4-5 weeks of chemoradiotherapy. Primary endpoints were changes in distance on the 6-minute walk test, hand-grip strength, lean muscle mass, and body weight between initiation and completion of intervention. RESULTS: Participants (mean age: 59.6 years) were mostly male (92.9%) with squamous cell carcinoma (96.4%). During chemoradiotherapy, participants who received the walk-and-eat intervention had 100-m less decline than controls in walk distance (adjusted p = .012), 3-kg less decrease in hand-grip strength (adjusted p = .002), and 2.7-kg less reduction in body weight (adjusted p < .001), regardless of age. The intervention group also had significantly lower rates of need for intravenous nutritional support and wheelchair use. CONCLUSION: The nurse-led walk-and-eat intervention is feasible and effective to preserve functional walking capacity and nutritional status for patients with esophageal cancer undergoing neoadjuvant chemoradiotherapy.

Long-term outcome after bilateral lung transplantation - a retrospective study from a low-volume center experience.

BACKGROUND: The aim of this study is to review the long-term outcomes of bilateral lung transplantation (BLTx) in our institution and examine the potential issues that may influence outcomes in a low-volume center. METHODS: A retrospective review of BLTx performed in our institution between July 2006 and December 2012 was conducted. Standardized donor selection, procurement, and preservation protocols for brain-dead donors were applied. Measured outcomes were in-hospital mortality and actuarial survival using the Kaplan-Meier method. RESULTS: Twenty-five consecutive patients (13 male, 12 female) underwent BLTx with a mean age of 41.8 ± 13.5 years. Before LTx, the mean body mass index was 18.3 ± 3.1 kg/m2. Seven of these patients (28%) required oxygen supplementation at rest before LTx, while the remaining patients (72%) required noninvasive mechanical ventilation (n = 6, 24%), invasive mechanical ventilation (n = 9, 36%) or extracorporeal membrane oxygenation (ECMO) (n = 3, 12%). The lung grafts were procured from brain-dead donors with the mean age of 26.8 ± 11.4 year and the best PaO2 / FiO2 ratio of 513 ± 77 before procurement. All cross match results between same-race donors and recipients were negative. The percentage of same-sex matching and CMV mismatching were 64% and 4%, respectively. The mean time listed on the transplant list was 308 ± 261 days. The mean ischemic time for the first and second grafts were 222 ± 62 and 361 ± 67 minutes. During transplantation, 22 (88%) patients depended on ECMO and one (4%) on cardiopulmonary bypass support. All but two patients (82%) were discharged home in good condition; two (8%) patients died within 3 months after BLTx. The cumulative survival rates at 1-, 2-, 3-, and 5-years were 88%, 83%, 72%, and 72%, respectively. CONCLUSIONS: Although the comparatively few annual LTx performed is consistent with the low donation rate, our single-center growing experience demonstrates that good post-lung transplant outcomes can be achieved at a low-volume LTx center.

Association of miRNA-related genetic polymorphisms and prognosis in patients with esophageal squamous cell carcinoma.

BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is a deadly disease with a poor prognosis. The single nucleotide polymorphisms (SNPs) involved in microRNA (miRNA) functions are potential biomarkers for prognosis of various human cancers. We investigated the association of the miRNA-related SNPs with the prognosis of ESCC. METHODS: A total of 504 patients with ESCC were enrolled. The genotypes of 18 miRNA-related SNPs were analyzed from the genomic DNA of peripheral leukocytes and were correlated with the prognosis of patients randomly assigned to a training set (n = 129) or an independent replication set (n = 375). RESULTS: In the training group, only the rs4919510 SNP of the mir-608 gene was significantly associated with clinical outcome (CG vs. GG, hazard ratio [HR] 0.47, 95 % confidence interval [CI] 0.27-0.82, P = 0.008 for death, HR 0.47, 95 % CI 0.29-0.77, P = 0.002 for recurrence). The association for overall survival was confirmed in an independent replication group (CG vs. GG, HR 0.74, 95 % CI 0.56-0.97, P = 0.031 for death). Two other SNPs, rs14035 of RAN and rs7813 of GEMIN4, showed a borderline significant association with the prognosis of ESCC. In a combined analysis, we demonstrated the cumulative effect of the mir-608, RAN, and GEMIN4 polymorphisms on the clinical outcome of ESCC (HR 1.40, 95 % CI 1.18-1.67, P trend < 0.001 for mortality, HR 1.30, 95 % CI 1.10-1.53, P trend = 0.002 for recurrence). The cumulative effect was more evident in patients receiving concurrent chemoradiotherapy. CONCLUSIONS: The hereditary genetic polymorphisms of mir-608, RAN, and GEMIN4 can serve as predictors for clinical outcome in ESCC patients treated with concurrent chemoradiotherapy.
