NIR-Responsive injectable hydrogel cross-linked by homobifunctional PEG for photo-hyperthermia of melanoma, antibacterial wound healing, and preventing post-operative adhesion. Mater Today Bio 2024; 26:101062. [PMID: 38706729 PMCID: PMC11066557 DOI: 10.1016/j.mtbio.2024.101062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 03/29/2024] [Accepted: 04/14/2024] [Indexed: 05/07/2024] Open
Abstract
Current therapeutic approaches for skin cancer face significant challenges, including wound infection, delayed skin regeneration, and tumor recurrence. To overcome these challenges, an injectable adhesive near-infrared (NIR)-responsive hydrogel with time-dependent enhancement in viscosity is developed for combined melanoma therapy and antibacterial wound healing acceleration. The multifunctional hydrogel is prepared through the chemical crosslinking between poly(methyl vinyl ether-alt-maleic acid) and gelatin, followed by the incorporation of CuO nanosheets and allantoin. The synergistic inherent antibacterial potential of CuO nanosheets, the regenerative and smoothing effect of allantoin, the extracellular matrix-mimicking effect of gelatin, and the desirable swelling behavior of the hydrogel results in fast wound recovery after photothermal ablation of the tumor. Additionally, the hydrogel can serve as an alternative to sutures owing to its tissue adhesiveness ability, which can further render it the merits for accelerated repair of abdominal lesions while acting as a biocompatible barrier to prevent peritoneal adhesion.

Adjuvant therapy provides no additional recurrence-free benefit for esophageal squamous cell carcinoma patients after neoadjuvant chemoimmunotherapy and surgery: a multi-center propensity score match study. Front Immunol 2024; 15:1332492. [PMID: 38375480 PMCID: PMC10875462 DOI: 10.3389/fimmu.2024.1332492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 01/17/2024] [Indexed: 02/21/2024] Open
Abstract
Purpose The need for adjuvant therapy (AT) following neoadjuvant chemoimmunotherapy (nICT) and surgery in esophageal squamous cell cancer (ESCC) remains uncertain. This study aims to investigate whether AT offers additional benefits in terms of recurrence-free survival (RFS) for ESCC patients after nICT and surgery. Methods Retrospective analysis was conducted between January 2019 and December 2022 from three centers. Eligible patients were divided into two groups: the AT group and the non-AT group. Survival analyses comparing different modalities of AT (including adjuvant chemotherapy and adjuvant chemoimmunotherapy) with non-AT were performed. The primary endpoint was RFS. Propensity score matching(PSM) was used to mitigate inter-group patient heterogeneity. Kaplan-Meier survival curves and Cox regression analysis were employed for recurrence-free survival analysis. Results A total of 155 nICT patients were included, with 26 patients experiencing recurrence. According to Cox analysis, receipt of adjuvant therapy emerged as an independent risk factor(HR:2.621, 95%CI:[1.089,6.310], P=0.032), and there was statistically significant difference in the Kaplan-Meier survival curves between non-AT and receipt of AT in matched pairs (p=0.026). Stratified analysis revealed AT bring no survival benefit to patients with pathological complete response(p= 0.149) and residual tumor cell(p=0.062). Subgroup analysis showed no significant difference in recurrence-free survival between non-AT and adjuvant chemoimmunotherapy patients(P=0.108). However, patients receiving adjuvant chemotherapy exhibited poorer recurrence survival compared to non-AT patients (p= 0.016). Conclusion In terms of recurrence-free survival for ESCC patients after nICT and surgery, the necessity of adjuvant therapy especially the adjuvant chemotherapy, can be mitigated.

Front Med (Lausanne) 2023; 10:1225179. [PMID: 37575989 PMCID: PMC10414536 DOI: 10.3389/fmed.2023.1225179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 07/10/2023] [Indexed: 08/15/2023] Open
Abstract
Introduction Patients with sepsis often require sedation and/or anesthesia. Although the immunomodulatory effects of anesthetics have been increasingly recognized, the molecular mechanisms require better elucidation. We compared the effects of sevoflurane with propofol on the expression of pro- and anti-inflammatory biomarkers released by monocytes/macrophages and blood/bronchoalveolar lavage fluid (BALF) neutrophils, the phagocytic capacity of monocytes/ macrophages, and neutrophil migration, as well as mediators associated with alveolar epithelial and endothelial cells obtained from rats with sepsis. Methods Polymicrobial sepsis was induced by cecal ligation and puncture in nine male Wistar rats. After 48 h, animals were euthanized and their monocytes/alveolar macrophages, blood and BALF neutrophils, as well as alveolar epithelial and endothelial cells were extracted, and then exposed to (1) sevoflurane (1 minimal alveolar concentration), (2) propofol (50 μM), or (3) saline, control (CTRL) for 1 h. Results Sevoflurane reduced interleukin (IL)-6 mRNA expression in monocytes and alveolar macrophages (p = 0.007, p = 0.029), whereas propofol decreased IL-6 mRNA only in alveolar macrophages (p = 0.027) compared with CTRL. Sevoflurane increased IL-10 expression (p = 0.0002) in monocytes compared with propofol and increased IL-10 mRNA and transforming growth factor (TGF)-β mRNA (p = 0.037, p = 0.045) compared with CTRL. Both sevoflurane and propofol did not affect mRNA expression of IL-10 and TGF-β in alveolar macrophages. The phagocytic capacity of monocytes (p = 0.0006) and alveolar macrophages (p = 0.0004) was higher with sevoflurane compared with propofol. Sevoflurane, compared with CTRL, reduced IL-1β mRNA (p = 0.003, p = 0.009) and C-X-C chemokine receptor 2 mRNA (CXCR2, p = 0.032 and p = 0.042) in blood and BALF neutrophils, and increased CXCR4 mRNA only in BALF neutrophils (p = 0.004). Sevoflurane increased blood neutrophil migration (p = 0.015) compared with propofol. Both sevoflurane and propofol increased zonula occludens-1 mRNA (p = 0.046, p = 0.003) in alveolar epithelial cells and reduced Toll-like receptor 4 mRNA (p = 0.043, p = 0.006) in alveolar endothelial cells compared with CTRL. Only propofol reduced surfactant protein B mRNA (p = 0.028) in alveolar epithelial cells. Discussion Sevoflurane, compared with propofol, increased anti-inflammatory biomarkers in monocytes, but not in alveolar macrophages, enhanced monocyte/alveolar macrophage phagocytic capacity and increased neutrophil migration in in vitro experimental sepsis. Both propofol and sevoflurane protected lung epithelial and endothelial cells.

The effect of anastomotic leakage on the incidence of recurrence after tri-modality therapy for esophageal adenocarcinomas. J Surg Oncol 2023. [PMID: 37133757 DOI: 10.1002/jso.27293] [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: 03/06/2023] [Accepted: 04/13/2023] [Indexed: 05/04/2023]
Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (nCRTx) reduces the incidence of recurrence, while anastomotic leakage has shown increase the risk of recurrence. The primary objective of this retrospective study was to investigate the incidence and pattern of recurrence and secondary median recurrence-free interval and post-recurrence survival in patients with and without anastomotic leakage after multimodal therapy for esophageal adenocarcinoma. METHODS Patients with recurrence after multimodal therapy between 2010 and 2018 were included. RESULTS Six hundred and eighteen patients were included, 91 (14.7%) had leakage and 278 (45.0%) recurrence. Patients with leakage did not develop recurrence more often (48.4%) than those without (44.4%, [p = 0.484]). Recurrence-free interval for patients with (n = 44) and without leakage (n = 234) was 39 and 52 weeks, respectively (p = 0.049). Post-recurrence survival was 11 and 16 weeks, respectively (p = 0.702). Specified by recurrence site, post-recurrence survival for loco-regional recurrences was 27 versus 33 weeks (p = 0.387) for patients with and without leakage, for distant 9 versus 13 (p = 0.999), and for combined 11 versus 18 weeks (p = 0.492). CONCLUSION AND DISCUSSION No higher incidence of recurrent disease was observed in patients with anastomotic leakage, however it is associated with a shorter recurrence-free interval. This could have implications for surveillance, as early detection of recurrent disease could influence therapeutic options.

Early postoperative weight loss is associated with poor prognosis in patients with esophageal cancer. Esophagus 2022; 19:596-603. [PMID: 35857177 DOI: 10.1007/s10388-022-00937-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 06/19/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Surgery for esophageal cancer (EC) causes morphological and functional changes in the upper gastrointestinal tract, resulting in postoperative weight loss (PWL). PWL has been shown to lead to poor nutritional status and immunocompetence, which may worsen the prognosis for several types of cancer. However, few reports have examined the relationship between weight loss (WL) in the early postoperative period and cancer prognosis. METHODS A total of 421 esophageal cancer patients underwent curative esophagectomy at Osaka University Hospital from 2010 to 2016. Based on the patients' body weight 1.5 months after surgery, they were classified into severe WL (n = 50) and slight-moderate WL (n = 371) groups. RESULTS The 5-year overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) were significantly lower in the severe WL group than the slight-moderate WL group (p = 0.0002, p < 0.0001, and p = 0.0004, respectively). In the multivariate analysis, tumor invasion depth (pT3, 4), lymph node metastasis (pN2, 3), preoperative Prognostic Nutrition Index (< 45), postoperative complications (≥ G3), and severe WL were independent prognostic factors for CSS (hazard ratio [HR] 2.5, 95% confidence interval [CI] 1.7-3.7; HR 1.6, 95% CI 1.1-2.4; HR 1.9, 95% CI 1.3-2.8; HR 1.6, 95% CI 1.1-2.4; and HR 2.7, 95% CI 1.7-4.2, respectively). In a multivariate analysis of risk factors leading to severe WL, thoracotomy (VATS) and postoperative MAX CRP (high) were independent risk factors (odds ratio [OR 0.48, 95% CI 0.24-0.97; OR 1.9, 95% CI 1.0-3.5). CONCLUSION Early PWL would be a useful marker of poor cancer prognosis in EC patients. Highly inflammatory conditions due to surgical invasion and postoperative complications may contribute to early PWL.

Abstract
BACKGROUND Nodal disease in esophageal and gastric cancer is associated with poor survival. OBJECTIVES To determine the critical level of lymph node involvement where survival becomes significantly compromised. METHODS Survival analyses using multivariable Cox regression and receiver operator characteristics (ROC) were undertaken to determine what number of positive lymph nodes were most sensitive and specific in predicting survival. RESULTS A total of 317 patients underwent esophagectomy (n = 190, 59.9%) and gastrectomy (n = 127, 40.1%) for adenocarcinoma. At multivariable analyses, four nodes positivity (irrespective of T-category) was associated with nearly a fivefold increased risk of mortality when compared to node-negative patients (hazard ratio [HR], 4.9; interquartile range 2.0-11.5; P < .001). A positive ratio of up to 50.0% was not associated with worse survival than having four nodes positive (HR, 4.6; 95% confidence interval, 2.6-8.1; P < .001). ROC analysis demonstrated four lymph nodes positive to have a sensitivity of 80.5%, a specificity of 60.1%, and an accuracy of 77.8 (P < .001). CONCLUSION The absolute number of nodes positive for cancer is more important than the proportion of positive nodes in predicting survival in esophageal/gastric cancer. Four positive lymph nodes are associated with a fivefold increase in mortality. Beyond this, increasing numbers of positive lymph nodes make no appreciable difference to survival.

Preoperative TruCulture® whole blood cytokine response predicts post-operative inflammation in pancreaticoduodenectomy patients-A pilot cohort study. Scand J Immunol 2020; 92:e12930.

Abstract
Major surgery is associated with substantial morbidity and mortality with early post-operative adverse events (POAE) occurring in 30% of patients within the first 30 days. The underlying pathogenesis is multifactorial, including immune dysfunction and increased inflammatory response to surgery. We investigated preoperative immune function by the TruCulture® whole blood technique in a cohort of patients undergoing pancreaticoduodenectomy (PD), hypothesizing that patients developing inflammatory POAE defined as leucocytosis, fever or high (above median) area under the curve (AUC) C-reactive protein (CRP) the first post-operative week would display perturbed preoperative immune function. Sixty-two adult patients were screened, 30 included and 11 excluded post-inclusion due to other surgical procedures than PD and post-operative complications directly attributed to surgery, leaving 19 patients for analysis of preoperative immune function. Patients developing leucocytosis (n = 5, 26%) had lower Toll-like receptor (TLR)-3-stimulated IL-12p40 and higher Candida Albicans (TLR1/2/4/6, Dectin-1)-stimulated TNF-α, compared to patients without leucocytosis (all P < .05). Patients developing fever (n = 7, 37%) had lower TLR7/8-stimulated IFN-γ and patients with high AUC CRP (n = 9, 47%) had lower TLR3-stimulated IFN-γ and IL-6 and lower TLR7/8-stimulated IL-10 (all P < .05), compared to patients without fever or low CRP, respectively. In conclusion, patients with inflammatory POAE displayed lower preoperative stimulated IL-12p40, IFN-γ, IL-6 and IL-10 and higher TNF-α response, compared to patients without inflammatory POAE. This finding suggests that TruCulture is a feasible immunologic screening tool in surgical patients, with a potential for preoperative identification of patients at increased risk for inflammatory POAE, allowing for risk-based intervention trials.

[PMID: 30668599 PMCID: PMC6342325 DOI: 10.1371/journal.pone.0211125] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Accepted: 01/08/2019] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Esophagectomy for esophageal cancer carries high morbidity and mortality, particularly in older patients. Transthoracic esophagectomy allows formal lymphadenectomy, but leads to greater perioperative morbidity and pain than transhiatal esophagectomy. Epidural analgesia may attenuate the stress response and be less immunosuppressive than opioids, potentially affecting long-term outcomes. These potential benefits may be more pronounced for transthoracic esophagectomy due to its greater physiologic impact. We evaluated the impact of epidural analgesia on survival and recurrence after transthoracic versus transhiatal esophagectomy. METHODS A retrospective cohort study was performed using the linked Surveillance, Epidemiology and End Results (SEER)-Medicare database. Patients aged ≥66 years with locoregional esophageal cancer diagnosed 1994-2009 who underwent esophagectomy were identified, with follow-up through December 31, 2013. Epidural receipt and surgical approach were identified from Medicare claims. Survival analyses adjusting for hospital esophagectomy volume, surgical approach, and epidural use were performed. A subgroup analysis restricted to esophageal adenocarcinoma patients was performed. RESULTS Among 1,921 patients, 38% underwent transhiatal esophagectomy (n = 730) and 62% underwent transthoracic esophagectomy (n = 1,191). 61% (n = 1,169) received epidurals and 39% (n = 752) did not. Epidural analgesia was associated with transthoracic approach and higher volume hospitals. Patients with epidural analgesia had better 90-day survival. Five-year survival was higher with transhiatal esophagectomy (37.2%) than transthoracic esophagectomy (31.0%, p = 0.006). Among transthoracic esophagectomy patients, epidural analgesia was associated with improved 5-year survival (33.5% epidural versus 26.5% non-epidural, p = 0.012; hazard ratio 0.81, 95% confidence interval [0.70, 0.93]). Among the subgroup of esophageal adenocarcinoma patients undergoing transthoracic esophagectomy, epidural analgesia remained associated with improved 5-year survival (hazard ratio 0.81, 95% confidence interval [0.67, 0.96]); this survival benefit persisted in sensitivity analyses adjusting for propensity to receive an epidural. CONCLUSION Among patients undergoing transthoracic esophagectomy, including a subgroup restricted to esophageal adenocarcinoma, epidural analgesia was associated with improved survival even after adjusting for other factors.

Perioperative enteral supplementation with glutamine, fiber, and oligosaccharide reduces early postoperative surgical stress following esophagectomy for esophageal cancer. Esophagus 2019; 16:63-70. [PMID: 30030739 DOI: 10.1007/s10388-018-0630-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Accepted: 07/16/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND We clarified the effects of perioperative enteral supplementation with glutamine, fiber, and oligosaccharide (GFO) after an esophagectomy on preventing surgical stress. METHODS Of 326 patients with esophageal cancer, 189 received GFO administration (GFO group) and 137 did not (control group). The propensity score matching method was used to identify 89 well-balanced pairs of patients to compare postoperative laboratory parameters and clinical and postoperative outcomes. RESULTS The duration of the systemic inflammatory response syndrome (SIRS) was significantly shorter in the GFO group compared to the control group (p = 0.002). Moreover, the lymphocyte/neutrophil ratio (L/N ratio) had significantly recovered in the GFO group on postoperative day-3, and the CRP value was significantly lower in the GFO group than that in the control group on postoperative day-2. CONCLUSIONS Perioperative use of enteral supplementation with glutamine, fiber, and oligosaccharide likely contributes to a reduction in early surgical stress after an esophagectomy. These beneficial effects can bring about early recovery from postoperative immunosuppressive conditions after radical esophagectomy.

Abstract
Background Little is understood regarding the inter-relation between economic, marital, and racial/ethnic differences in presentation and survival of surgically resected lung cancer patients. Our investigation will assess these differences in addition to known therapeutic, patient, and histopathologic factors. Methods A retrospective review of the Surveillance Epidemiology and End Reporting database was conducted through the years 2007–2012. The population was split into nine different ethnic groups. Population differences were assessed via chi-square testing. Multivariable analysis (MVA) were used to detect overall survival (OS) differences in the total surgical population (TS, N = 35,689) in an ear (T1–T2 < 4 cm N0) surgical population [early-stage resectable (ESR), N = 17,931]. Lung cancer-specific survival (LCSS) was assessed in the ESR. Results In the TS population, as compared to Whites, Blacks, and Hispanics presented with younger age, more adenocarcinomas, lower rates of marriage, lower rates of insurance, less stage I tumors, and had less nodes examined, but their type of surgical procedures and OS/LCSS were the same. MVA demonstrated that lower OS and LCSS were associated with males, single/divorced/widowed partnership, lower income (TS only), and Medicaid insurance. MVA also found that Blacks and Hispanics had a similar OS/LCSS to Whites and that all ethnic groups were associated with a similar or better outcomes. The 90-day mortality and positive nodes were correlated with not having insurance and not being married, but they were not associated with ethnicity. Conclusion In TS and ESR groups, OS was not different in the two largest ethnic groups (Black and Hispanic) as compared to Whites, but was related to single/widowed/divorced status, Medicaid insurance, and income (TS group only). Nodal positivity was associated with patients who did not have a married partner or insurance suggesting that these factors may impact disease biology. Economic and psychosocial variables may play a role in survival of ear lung cancer in addition to standard histopathologic and treatment variables.

Effect of perioperative blood transfusion on the long-term survival of patients undergoing esophagectomy for esophageal cancer: a systematic review and meta-analysis. Dis Esophagus 2018; 31:4757112.

Abstract
Perioperative blood transfusion has been linked to poorer long-term survival in patients undergoing esophagectomy, presumably due to its potential immunomodulatory effects. This review aims to summarize existing evidence relating to the influence of blood transfusion on long-term survival following esophagectomy for esophageal cancer. A systematic literature search (up to February 2017) was conducted for studies reporting the effects of perioperative blood transfusion on survival following esophagectomy for esophageal cancer. Meta-analysis was used to summate survival outcomes. Twenty observational studies met the criteria for inclusion. Eighteen of these studies compared the outcomes of patients who received allogenic blood transfusion to patients who did not receive this intervention. Meta-analysis of outcomes revealed that allogenic blood transfusion significantly reduced long-term survival (HR = 1.49; 95% CI 1.26 to 1.76; P < 0.001). There appeared to be a dose-related response with patients who received ≥3 units of blood having lower long-term survival compared to patient who received between 0 and 2 units (HR = 1.59; 95% CI 1.31 to 1.93; P < 0.001). Two studies comparing patients who received allogenic versus autologous blood transfusion showed superior survival in the latter group. Factors associated with the requirement for perioperative blood transfusion included: intraoperative blood loss; preoperative hemoglobin; operative approach; operative time, and; presences of advanced disease. These findings indicate that perioperative blood transfusion is associated with significantly worse long-term survival in patients undergoing esophagectomy for esophageal cancer. Autologous donation of blood, meticulous intraoperative hemostasis, and avoidance of unnecessary transfusions may prevent additional deaths attributed to this intervention.

Abstract
Obesity has been variously associated with reduced or similar rates of postoperative complications compared to normal weight patients undergoing esophagectomy for cancer. In contrast, little is known about esophagectomy risks in the underweight population. The relationship between the extremes of body mass index (BMI) and postoperative complications after esophagectomy was evaluated. Consecutive esophagectomy patients (2000-2013) were reviewed. The patients were stratified based on BMI at the time of diagnosis: underweight (<18.5), normal (18.5-24.9), overweight (25-29.9), obese I (30-34.9), and obese II or III (≥35). Hospital length of stay as well as postoperative complications and their accordion severity grading were evaluated according to the BMI category. Of 388 patients, 78.6% were male with a median age of 62 years at the time of operation. Pathologic cancer stage was 0 to I in 53%. BMI distribution was as follows: 5.6% underweight, 28.7% normal, 31.4% overweight, 22.8% obese I, and 11.5% obese II or III. Performance status was 0 or 1 in 99.2%. Compared to normal BMI patients, underweight patients had increased pulmonary complications (odds ratio (OR) 3.32, P = 0.014) and increased other postoperative complications (OR 3.00, P = 0.043). Patients who were overweight did not have increased complications compared to normal BMI patients. BMI groups did not differ in mortality rates or complication accordion severity grading. Hospital length of stay trended toward a longer duration in the underweight population (P = 0.06). Underweight patients are at increased risk for postoperative pulmonary and other complications. Underweight patients may benefit from preoperative nutritional repletion and mitigation for sarcopenia. Aggressive postoperative pulmonary care may help reduce complications in these patients. In contrast, the operative risk in overweight and obese patients is similar to normal BMI patients.

Abstract
BACKGROUND The purpose of this study was to provide more insight in the course of cytokine concentrations related to pathologic response (pR) and complications after neoadjuvant chemoradiotherapy (NCRT) and esophagectomy in esophageal cancer patients. METHODS Patients treated with NCRT followed by transthoracic esophagectomy (n = 35) or transthoracic esophagectomy alone (n = 8) were included. Eight different cytokine concentrations were determined during NCRT, esophagectomy, and the first postoperative week. RESULTS Platelet-activating factor before NCRT was associated with pR (P = .011) and remained elevated in patients with a better response. Concentrations of intestinal fatty acid-binding protein and angiopoietin 1 (Ang-1) were different between patients with and without NCRT. Decreased concentrations of Ang-1 on the third postoperative day were associated with postoperative complications (P = .046). CONCLUSIONS In this observational study, elevated platelet-activating factor concentrations before NCRT were associated with pR. NCRT is associated with decreased Ang-1 concentrations, whereas reduced Ang-1 concentrations were associated with postoperative complications.

Abstract
OBJECTIVE Laparoscopic surgery may offer advantages compared to open surgery, such as earlier mobilization, less pain and lower post-surgical morbidity. Surgical stress is thought to be associated with the postoperative immunological changes in the body as an impaired immune function, which may lead to an increased susceptibility to complications and morbidity. The aim of this review was to investigate if laparoscopic surgery reduces the immunological response compared to open surgery in gastric cancer. METHODS We conducted a literature search identifying relevant studies comparing laparoscopy or laparoscopic-assisted surgery with open gastric surgery. The main outcome was postoperative immunological status defined as surgical stress parameters, including inflammatory cytokines and blood parameters. RESULTS We identified seven studies that addressed the immunological status in patients undergoing laparoscopic or laparoscopy-assisted surgery compared to open surgery. IL-6 in circulation was found to be significantly reduced in laparoscopic patients. Furthermore, the plasma concentration of C-reactive protein was significantly lower in laparoscopic patients compared to patients undergoing laparotomy. Finally, most studies reported lower levels of white blood cell count in laparoscopic patients, although this result did not reach statistical significance in a small number of studies. CONCLUSIONS Laparoscopy-assisted gastric surgery seems to attenuate the immune response compared to open surgery. Larger and prospective studies are needed to further evaluate if the immunological status is relatively preserved in minimal invasive surgery and if this may reduce the postoperative complications compared to open surgery.

Abstract
BACKGROUND Cardiac complications are an important cause of morbidity and mortality observed after esophageal resections. We examined whether an high intrathoracic vagotomy during abdominothoracic esophagectomy would have an effect on intraoperative and early postoperative cardiac function in the setting of a minimally invasive resection. Two hypotheses were generated for this study: (1) Vagotomy would cause cardiac changes, and (2) vagus-preserving esophagectomy would prevent cardiac problems during resection and in the early postoperative phase. METHODS AND RESULTS Thirty male pigs were operated on while cardiac parameters (heart rate [HR], cardiac index [CI], preload recruitable stroke work [PRSW], contractility speed [dp/dtmax], relaxation speed [dp/dtmin], and relaxation time [tau]) were monitored using a conductance catheter and the thermodilution method. Animals were randomized into 4 groups (each n = 7): (1) control, thoracoscopy only, (2) thoracoscopy with vagotomy, (3) esophageal resection with vagotomy, and (4) esophageal resection with vagus nerve preservation. To evaluate the first hypothesis, we compared groups 1 and 2; to evaluate the second hypothesis, we compared groups 3 and 4. HR, CI, PRSW, dp/dtmax, and tau were different in the 2 groups without resection (area under the curve; each P < .05). Vagotomy with esophagectomy resulted in nonsignificant differences between groups 3 and 4. The requirement for metoprolol administration to avoid severe tachycardia was greater in the groups that underwent vagotomy (P < .05; Fisher's exact test). CONCLUSION An high intrathoracic vagotomy results in loss of vagal tone and a greater rate of tachycardia during thoracoscopy and esophagectomy. There were no differences, however, in cardiac dynamics between the esophagectomy groups. Thus, vagal injury is not the sole reason for cardiac dysfunction after esophagectomy.

Abstract
OBJECTIVE To investigate the incidence of BT in the mesenteric lymph node and bacteremia after an esophagectomy using a bacterium-specific ribosomal RNA-targeted reverse-transcriptase quantitative polymerase chain reaction (RT-qPCR). BACKGROUND There is little evidence regarding the occurrence of bacterial translocation (BT) and its correlation to postoperative infectious complications after an esophagectomy. METHODS Eighteen patients with esophageal cancer were studied. Mesenteric lymph nodes were harvested from the jejunal mesentery before surgical mobilization (MLN-1) and after the restoration of bowel continuity (MLN-2). Blood and sputum were also sampled before surgery (Blood-1 and Sputum-1) and on postoperative day 1 (Blood-2 and Sputum-2). RESULTS The detection rates of bacteria in the MLN-2 (56%) and Blood-2 (56%) were significantly higher than those in the MLN-1 (17%) and Blood-1 (22%), indicating that surgical stress induces BT. The detection rate was not different between Sputum-1 (80%) and Sputum-2 (78%). There was an 80% sequence homology between the RT-qPCR products in the MLN-2 and Blood-2, whereas the homology was only 20% between Blood-2 and Sputum-2. In the patients with positive bacteria in the MLN-2 sample, there was a greater incidence of postoperative infectious complications than in patients without bacteria in the MLN-2 sample (P = 0.04). The postoperative hospital stay was also longer (P = 0.037) for patients with positive bacteria in the MLN-2 sample. CONCLUSIONS BT frequently occurs during esophagectomies, and postoperative bacteremia is likely to be gut-derived. Patients with positive bacteria in the MLN-2 sample should be carefully managed because these patients are more susceptible to postoperative infectious complications.

Abstract
Esophageal cancer (EC) is one of the most aggressive gastrointestinal malignancies, possessing an insidious onset and a poor prognosis. Numerous transcription factors and inflammatory mediators have been reported to play a pivotal role in the initiation and progression of this cancer. However, the specifics of the signaling network responsible for said factors, especially which elements are the critical regulators, are still being elucidated. Glycogen synthesis kinases 3 (GSK3)β was originally regarded as a kinase regulating glucose metabolism. Accumulating evidence demonstrated that it also played an essential role in a variety of cellular processes including proliferation, differentiation, inflammation, motility, and survival by regulating various transcription factors such as c-Jun, AP-1, β-catenin, CREB, and NF-κB. Aberrant regulation of GSK3β has been shown to promote cell growth in some cancers, while suppressing it in others, and thus may play an important role in the development of EC. This review will discuss our current understanding of GSK3β signaling, and its control of the expression and activation of various transcription factors that mediate the inflammatory response. We will also explore some of the known mediators of EC progression, and based on current literature, elucidate the potential roles and implications of GSK3 in this disease.

Abstract
BACKGROUND Major surgery suppresses the cell-mediated immune response in children and adults. Data on preoperative and postoperative T-cell counts in pediatric surgical patients and their relationship to health-care-associated infection (HAI) are not yet known. METHODS A prospective observational study was carried out in a level III multidisciplinary neonatal and pediatric intensive care unit. Before and after, and in the first 3 days after surgery, lymphocyte subsets in peripheral blood were measured in 28 neonates and infants on flow cytometry. HAI were classified according to CDC/NHSN criteria. RESULTS Six out of 28 neonates and infants (21.4%) developed HAI (group I-HAI), while 22 out of 28 (78.6%) remained infection free (group II-non-HAI). In group I with HAI, the preoperative median cytotoxic T-lymphocyte (CD8-T-cell) level was found to be below normal, and remained very low throughout the study period. In addition, the median and interquartile CD8 T-cell range (358 cells/μL; 304-424 cells/μL) were twice as low compared to group II without HAI (822 cells/μL; 522-933 cells/μL; P = 0.013). No differences were found between the two groups with regard to patient demographics and clinical data. CONCLUSION Neonates and infants who underwent a major surgical procedure and who had a very low preoperative CD8 T-cell level, developed HAI postoperatively.

Assessment of morbidity and mortality after esophagectomy using a modified frailty index. Ann Thorac Surg 2013; 96:1240-1245. [PMID: 23915593 DOI: 10.1016/j.athoracsur.2013.05.051] [Citation(s) in RCA: 77] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2013] [Revised: 05/09/2013] [Accepted: 05/14/2013] [Indexed: 12/11/2022]
Abstract
BACKGROUND Esophagectomy is associated with significant morbidity and mortality. This retrospective study examined use of a modified frailty index as a potential predictor of morbidity and mortality in esophagectomy patients. METHODS National Surgical Quality Improvement Program Participant Use Files were reviewed for 2005 through 2010. Patients undergoing esophagectomy were selected based on CPT codes. A modified frailty index with 11 variables was used to determine correlation between frailty and postesophagectomy morbidity and mortality. Data were analyzed using χ(2) test and logistic regression. RESULTS A total of 2,095 patients were included in the analysis. Higher frailty scores were associated with a statistically significant increase in morbidity and mortality. A frailty score of 0, 1, 2, 3, 4, and 5 had associated morbidity rates of 17.9% (142 of 795 patients), 25.1% (178 of 710 patients), 31.4% (126 of 401 patients), 34.4% (48 of 140 patients), 44.4% (16 of 36 patients), and 61.5% (8 of 13 patients), respectively. A frailty score of 0, 1, 2, 3, 4, and 5 had associated mortality rates of 1.8% (14 of 795 patients), 3.8% (27 of 710 patients), 4% (16 of 401 patients), 7.1% (10 of 140 patients), 8.3% (3 of 36 patients), and 23.1% (3 of 13 patients), respectively. When using multivariate logistic regression for mortality comparing age, functional status, prealbumin, emergency surgery, wound class, American Society of Anesthesiologists score, and sex, only age and frailty were statistically significant. The odds ratio was 31.84 for frailty (p = 0.015) and 1.05 (p = 0.001) for age. CONCLUSIONS Using a large national database, a modified frailty index was shown to correlate with postesophagectomy morbidity and mortality. Such an index may be used to aid in improving risk assessment and patient selection for esophagectomy.

Abstract
Aim: Esophagectomy is the primary surgical treatment for localized malignant neoplasms of the esophagus, and while outcomes have shown that substantial improvement has been made, the ceiling for improvement is still high. Methods: A total of 2506 publications published from January 2002 to March 2012 were identified from PubMed, MEDLINE and the Cochrane Library using the keywords: ‘esophagectomy’, ‘esophagus’, ‘neoplasm’ and ‘cancer’ to identify quality key surgical articles in esophagectomy that were broken down into three groups: preoperative, intraoperative and postoperative care. Discussion: There have been limited preoperative surgical trials, mostly in preoperative antibiotic use, which have led to changes in surgical management. Key and substantial changes have occurred in the intraoperative management for esophageal malignancies around surgical anastomosis technique and anesthesia. Nutritional outcomes still remain a key challenge, and currently there is no established standard of care in the postoperative management of esophagectomy patients. Conclusion: We established quality parameters for leak rates, overall morbidity and mortality, and these form the foundation from which all esophageal surgeons should rank their results. We then utilized the techniques described above to maintain those rates or, better yet, to significantly improve those rates in each surgeons’ practice.

Abstract
PURPOSE The aim of this study was to investigate the effect of high-intensity focused ultrasound (HIFU) on immune function in patients with uterine fibroids, in a randomised comparison to conventional myomectomy. METHODS The patients were assigned (1:1) to the HIFU group or the myomectomy (MY) group. Venous blood samples were collected 24 h before and 24 h and 72 h after operation. The percentages of CD4(+) and CD8(+) T cells and natural killer (NK) cells were quantified by flow cytometry (FCM). Serum levels of interleukin-2 (IL-2), IL-6 and IL-10 were determined using enzyme-linked immunosorbent assay. RESULTS HIFU was associated with early ambulation, fewer post-operative complications, and shorter hospital stay (p < 0.001). The percentages of CD4(+) and CD8(+) T cells and NK cells in the HIFU group were not significantly altered after treatment compared with before treatment. In contrast, the numbers of these cells in the MY group decreased significantly 24 h after conventional myomectomy (p < 0.001). The CD4(+)/CD8(+) T cell ratios were also decreased significantly 24 h and 72 h after conventional myomectomy (p < 0.001). Serum levels of IL-6 and IL-10 increased after treatment in both groups. Peak IL-6 and IL-10 levels were significantly lower in the HIFU group than in the MY group (p < 0.001). In contrast, IL-2 level decreased significantly in the MY group compared to the HIFU group at 24 h post-operation (p < 0.001). CONCLUSIONS Short-term post-operative immune function is better preserved after HIFU treatment. Better preserved immune function may reflect a reduction in tissue trauma after HIFU treatment and contribute to reduced post-operative complications.

Abstract
Background Surgery plays a key role in HIV palliative care, specifically in the diagnosis and treatment of HIV related and non-related conditions. Yet major surgery depresses the immune system. Whereas the surgical consequences of HIV infection are well described, there is a paucity of published data, in resource-limited settings, on the effects of major surgery on the immune system. The purpose of this study was to determine the effect of major abdominal surgery on CD4 count in HIV positive and HIV negative patients after emergency major surgery. Methods A prospective cohort study was done for patients who underwent emergency major abdominal surgery. Their peri-operative CD4 counts were done for both HIV- and HIV + patients. Median CD4s were used in analysis. Mann Whitney test of significance was used for continuous data and Fisher’ exact test used for categorical data. IRB approval was obtained. Results A total of 101 patients were recruited, 25 HIV positive and 76 HIV negative. The median CD4 cell reduction was higher in the HIV negative group (−68 cells) than HIV positive group (−29 cells) (p = 0.480). There was a general increase in the median CD4 change by 72 cells for the HIV positives and 95 cells for the HIV negatives (p = 0.44). CD4 change rose in both the HIV positive and negative groups by 27 cells for the HIV positives and 28 cells for the HIV negatives (p = 0.94). Relative Risk was 0.96, {CI 0.60 – 1.53}. Conclusion Major emergency abdominal surgery had no significant effect on CD4 cell count among HIV positive patients.

Abstract
Malnutrition is common 1 year after esophageal cancer surgery. However, the prognostic impact of this malnutrition on long-term outcome has been poorly reported. This study aims at determining the potential effect on disease-free survival (DFS) of weight loss observed at 1 year in disease-free survivors after curative esophageal resection. From a prospective single-institution database, 304 patients having undergone a transthoracic esophagectomy with two-field lymphadenectomy and gastric reconstruction between 1996 to 2008 were identified. Patients who died during the postoperative course (n= 24), patients who died within the first postoperative year (n= 12), patients who presented with an early recurrence within the first postoperative year (n= 20), and those who were lost to follow-up (n= 22) were excluded from the study, as well as those for whom the follow-up was shorter than 1 year (n= 21). The remaining 205 patients constituted a homogeneous group of 1-year disease-free survivors after full postoperative work-up and formed the material of the present study. Body weight (BW) values were collected before any treatment at the onset of symptoms (initial BW) and 1 year after esophagectomy. A 1-year weight loss (1-YWL) exceeding 10% of the initial BW defined an important malnutrition. Impact of the 1-YWL ≥ or <10% of the initial BW on DFS was investigated. Logistic regression was performed to identify factors affecting DFS. The mean initial BW was 69.1 ± 12 kg, corresponding to a mean body mass index (BMI) of 23.8 ± 3 kg/m(2) . Preoperatively, 32 (15%) patients were in the underweight category (BMI < 20 kg/m2), 110 (54%) were in normal (BMI = 20-24 kg/m2), and 63 (31%) were in the overweight category (BMI ≥ 25 kg/m2). Mean 1-year BW was 63.5 ± 12 kg. 1-YWL was <10% of the initial BW in 92 patients (45%) and ≥ 10% in 113 patients (55%). Accordingly, 5-year DFS rates were 66% (median: 80 months) and 48% (median: 51 months), respectively (P= 0.005). On multivariate analysis, only three independent variables affected the DFS significantly: clinical N stage (cN) status (P= 0.007; odds ratio: 1.99, 1.2-3.3), incomplete resection (P= 0.008, OR: 3.6, 1.3-9.3), and 1-YWL ≥ 10% (P= 0.004, OR: 2.1: 1.2-3.4). 1-YWL of or exceeding 10% of the initial BW in 1-year disease-free survivors has a negative prognostic impact on DFS after esophagectomy for cancer. This information offers another view on the objectives of the perioperative nutritional care of these patients. Special vigilance program on the nutritional status in post-esophagectomy patients should be the rule.

Abstract
The development of surgical and postoperative management techniques has improved the treatment outcomes of esophageal cancer resection. However, respiratory morbidity is still the most frequent complication after esophagectomy. The objective of the present study was to identify risk factors for respiratory complications following resection for esophageal cancer. This study included 96 patients with esophageal cancer who had undergone esophagectomy with lymph node dissection. The patients were divided into 2 groups according to the presence (20 patients, 17 had pneumonia and 3 had acute respiratory distress syndrome) or absence (76 patients) of postoperative respiratory complications (PRC). The two groups were compared with respect to their preoperative clinical variables, such as age, body mass index, smoking history, serum albumin, serum C-reactive protein (CRP), number of lymphocytes, %VC, FEV1.0% and FEV1.0. Furthermore, multiple logistic regression analyses were used to estimate relative risk factors for respiratory complications. Results of the univariate analysis showed that smoking history (+/-, patients with PRC, 19/1 and without PRC, 53/23), serum CRP (≥1.0 mg/dl/<1.0 mg/dl, patients with PRC, 6/14 and without PRC, 6/70) and FEV1.0% (≥60%/<60%, patients with PRC, 16/4 and without PRC, 73/3) were significantly different between the two groups. Multiple logistic regression analysis showed that FEV1.0% was the strongest predictor of PRC. FEV1.0%, serum CRP and smoking history are reliable predictors of the risk of respiratory complications following esophageal cancer resection. For patients with these factors, perioperative management for the prevention of postoperative respiratory complications should be considered.

Abstract
Background Thoracic surgery mandates usually a one-lung ventilation (OLV) strategy with the collapse of the operated lung and ventilation of the non-operated lung. These procedures trigger a substantial inflammatory response. The aim of this study was to analyze the cytokine and chemokine reaction in both lungs, pleural space and blood in patients undergoing lung resection with OLV with special interest in the chemokine growth-regulated peptide alpha (GROα) which is the human equivalent to the rat cytokine-induced neutrophil chemoattractant-1 (CINC-1). Methods Broncho-alveolar lavage (BAL) fluid of both the collapsed, operated and the ventilated, non-operated lung, respectively, pleural space drainage fluid and blood was collected and the concentrations of interleukin (IL)-6, IL-1RA and GROα were determined with enzyme-linked immunosorbent assays in 15 patients. Results Substantial inter-individual differences in the BAL fluid between patients in cytokine and chemokine levels occurred. In the pleural fluid and the blood these inter-individual differences were less pronounced. Both sides of the lung were affected and showed a significant increase in IL-6 and IL-1RA concentrations over time but not in GROα concentrations. Except for IL-6, which increased more in the collapsed, operated lung, no difference between the collapsed, operated and the ventilated, non-operated lung occurred. In the blood, IL-6 and IL-1RA increased early, already at the end of surgery. GROα was not detectable. In the pleural fluid, both cytokine and chemokine concentrations increased by day one. The increase was significantly higher in the pleural fluid compared to the blood. Conclusion The inflammatory response of cytokines affects both the collapsed, operated and the ventilated, non-operated lungs. The difference in extent of response underlines the complexity of the inflammatory processes during OLV. In contrast to the cytokines, the chemokine GROα concentrations did not react in the BAL fluid or in the blood. This indicates that GROα might not be useful as marker for the inflammatory reaction in complex surgical procedures.

Abstract
Persons with rheumatoid arthritis (RA) suffer a high burden of infections, but currently no biomarkers are available to identify individuals at greatest risk. A prospective longitudinal study was therefore conducted to determine the association between the responsiveness of ex vivo cytokine production and 6-month risk of infections. Infections were identified by billing codes and validated by medical record review. At baseline, the release of 17 cytokines by peripheral blood mononuclear cells in response to stimulation, or media alone, was measured using multiplexed cytokine analysis. Production of IL-2, IL-8, IL-10, IL-17, TNF-α, IFN-γ, and GM-CSF, induced by various conditions, was significantly associated with the occurrence of infections. A multivariable prediction model based on these data provided new information on the risk of infection beyond standard assessments of disease activity, severity, and treatment. Future studies could utilize this information to devise new biomarkers for the prediction of infection in patients with RA.

Abstract
In this review the preoperative risk assessment and prevention of complications in patients undergoing esophagectomy for cancer is discussed. Age, pulmonary and cardiovascular condition, nutritional status, and neoadjuvant chemo(radio)therapy are known predictive factors. None of these factors is a valid exclusion criterion for esophagectomy, but may help in careful patient selection. Both anesthetists and surgeons play an important role in intraoperative risk reduction by means of appropriate fluid management and application of optimal surgical techniques.

Abstract
AIMS The morbidity rate of hepatic resection for hepatocellular carcinoma (HCC) remains high. To clarify predictors and the prognostic significance of operative complications in patients with HCC, we conducted a comparative retrospective analysis of 291 patients with HCC who underwent hepatic resection. METHODS Operative complications included hyperbilirubinemia, ascites, hemorrhage, respiratory and cardiovascular diseases, bile leakage and abscess formation, renal failure, wound infection, and pleural effusion. Predictors of operative complications and their prognostic value for long-term survival were studied by univariate and multivariate analyses. RESULTS Mortality and morbidity rates were 7.2% and 42.6%. The main operative complications were ascites (n = 30), intraabdominal abscess (n = 25), hyperbilirubinemia (n = 19), wound infection (n = 16), pleural effusion (n = 10) and intraabdominal hemorrhage (n=9). By a multivariate logistic regression model, Child-Pugh class B and increased operative blood loss (> or = 1200ml) were independent predictors of postoperative complications. Among 243 patients without operative death, the 5-year overall survival rate was significantly lower in patients with operative complications (34.3%) than in those without these complications (48.7%). By the multivariate Cox proportional hazards model, the presence of operative complications was an independent predictor of poor overall survival as well as presence of portal invasion. CONCLUSIONS Child-Pugh class B and operative blood loss > or = 1200ml were independent predictors of complications after hepatic resection for HCC. Long-term survival is poorer in patients with postoperative complications. Decreasing operative blood loss may result in fewer postoperative complications and better long-term survival of HCC patients.

Abstract
Background Th1/Th2 cell balance is thought to be shifted toward a Th2-type immune response not only by malignancy but also by surgical stress. The aim of this study was to estimate perioperative immune responses with respect to the Th1/Th2 balance in patients with gastrointestinal cancer. Methods Ninety-four patients who underwent abdominal surgeries were divided into three groups: gastric resection (n = 40), colorectal resection (n = 34) and hepatic resection (n = 20). Twelve patients undergoing laparoscopic cholecystectomy and 20 healthy subjects were served as control groups. Intracellular cytokine staining in CD4+ T lymphocytes was identified to characterize Th1/Th2 balance. Th1/Th2 balance was evaluated before operation and until postoperative days (POD) 14. Results The preoperative Th1/Th2 ratio was significantly lower in patients with malignancy compared with control. The Th1/Th2 ratio of patients in all groups decreased significantly postoperatively. Th1/Th2 balance on POD 2 in patients with malignancy was significantly decreased compared to patients with laparoscopic cholecystectomy, but there were no significant differences among the four groups on POD 14. Conclusion Patients with malignancy showed an abnormal perioperative Th1/Th2 balance suggesting predominance of a type-2 immune response. Major abdominal surgeries induce a marked shift in Th1/Th2 balance toward Th2 in the early postoperative stage.

Differential responses of cellular immunity in patients undergoing neoadjuvant therapy followed by surgery for carcinoma of the oesophagus. Cancer Immunol Immunother 2008; 57:1837-47.

Abstract
BACKGROUND To compare immune responses following neoadjuvant chemoradiation therapy in combination with hyperthermia plus surgery to those induced by surgery alone in patients with oesophageal cancer. METHODS Thirty-two patients with histopathologically proven oesophageal cancer, scheduled for potentially curative transhiatal or transthoracic oesophagectomy with (neo, n = 20) or without (control, n = 12) neoadjuvant thermochemoradiation therapy (ThCR) were included. Peripheral blood samples were obtained before ThCR, after 2 weeks of ThCR, 1 day before surgery, on postoperative days 1, 3, 7, and 6 weeks after surgery, for white blood cell counts, lymphocyte subsets and T helper type 1 (Th1) and type 2 (Th2) lymphocyte responses. RESULTS Neo patients showed a significant decrease in granulocytes and lymphocyte subsets, and T cell cytokines after 2 weeks of ThCR. Only CD8+ (cytotoxic) T cells recovered after ThCR to reach normal levels prior to surgery. In contrast, CD4+ T (helper) cells, and NK- and B cells in neo patients did not recover prior to surgery (all P < 0.05). Oesophagectomy induced a significant increase in granulocytes and a decrease in lymphocytes (and subsets). Only those subsets that had not recovered after ThCR (CD4+ T cells, NK and B cells but not CD8+ T cells), were significantly lower (all P < 0.05) during the entire postoperative study period. Postoperatively, the stimulated cytokine production capacity of Th1 and Th2 cells, corrected for number of T cells, was not significantly different between the groups. CONCLUSION Neoadjuvant thermochemoradiation for oesophageal cancer caused significant disturbances of host cellular immunity with reduced T, NK and B cell counts, and differential recovery of cytotoxic and helper T cells leading to prolonged T cell imbalance that extends beyond the time of surgery. The functional and anti-tumour consequences of this immunodisturbance need further investigation, as recovery of T helper cytokine production towards surgery was less impaired than T helper cell counts.

The number of metastatic lymph nodes and the ratio between metastatic and examined lymph nodes are independent prognostic factors in esophageal cancer regardless of neoadjuvant chemoradiation or lymphadenectomy extent.

Abstract
OBJECTIVE To investigate whether the number of lymph nodes metastasis (LNMs) and the ratio between metastatic and examined lymph nodes (LNs) are better prognostic factors when compared with traditional staging systems in patients with esophageal carcinoma. SUMMARY BACKGROUND DATA The accuracy of the 6th UICC/TNM classification is suboptimal, especially when not taking into account neoadjuvant therapy and lymphadenectomy extent. METHODS For 536 patients who underwent curative en bloc esophagectomy, in whom 51.5% (n = 276) received neoadjuvant chemoradiation, LNMs were classified according to the 6th UICC/TNM classification and systems based on the number (< or =4 and >4) or the ratio (< or =0.2 and >0.2) of LNMs. Survival of the respective stages, predictors of survival, and influence of both chemoradiation and number of examined LNs were studied. RESULTS After a median follow-up of 50 months, the 5-year survival rates were 47% for the entire population, significantly poorer for patients with >4 LNMs (8% vs. 53%, P < 0.001) or a ratio of LNMs >0.2 (22% vs. 54%, P < 0.001). After adjustment for confounding variables, a number of LNMs >4 and a ratio of LNMs >0.2 were the only predictors of poor prognosis. The prognostic role of both the number and the ratio of LNMs was maintained whether patients received neoadjuvant chemoradiation or not. Moreover, LN ratio is shown to be more accurate for inadequately staged patients (<15 examined LNs), whereas the number of LNMs is pertinent for adequately staged patients (> or =15 examined LNs). CONCLUSION Staging systems for esophageal cancer that use the number (< or =4 or >4) and the ratio (< or =0.2 or >0.2) of LNMs have greater prognostic importance than the current staging systems because of the good stratification of the groups and their clinical utility, taking into account neoadjuvant therapy and lymphadenectomy extent.

Abstract
Immunosuppression in a patient with malignant tumor is a major obstacle in cancer treatment. In this study, we investigated changes in the circulating level of all measured immunosuppressive cytokines in patients with malignancy before and after high intensity focused ultrasound (HIFU) treatment. Fifteen patients with solid malignancy were enrolled in this study and an enzyme-linked immunoabsorbent assay (ELISA) method was used to measure serum level of vascular endothelial growth factor (VEGF), transforming growth factor-beta1 (TGF-beta1), transforming growth factor-beta2 (TGF-beta2), interleukin 6 (IL-6) and interleukin 10 (IL-10), respectively before and 1 wk after HIFU treatment. Among them, seven patients had distant metastasis and the remaining eight had no metastasis. All patients received one-session HIFU treatment for primary cancer, including complete ablation in eight patients without metastasis, and partial ablation in seven patients with metastases. The results showed that serum immunosuppressive cytokine levels decreased after HIFU treatment, and there were significant decreases of VEGF, TGF-beta1, and TGF-beta2 before and after HIFU treatment. Compared with the values in the metastatic patients, serum levels of immunosuppressive cytokines were significantly lower in the nonmetastatic patients after HIFU treatment. It is concluded that HIFU can decrease tumor-secreted immunosuppressive cytokine production in addition to its direct tumor destruction. This change may lessen tumor-induced immunosuppression and renew antitumor immunity after HIFU in cancer patients.

Abstract
Mannose-binding lectin (MBL) deficiency due to variations in the MBL gene is associated with increased susceptibility to infections. In this study, the association between MBL deficiency and the occurrence of abdominal yeast infection (AYI) in peritonitis patients was examined. Eighty-eight patients with secondary peritonitis requiring emergency laparotomy were included. MBL genotype (wild type [WT] versus patients with variant genotypes), MBL plasma concentrations, and Candida risk factors were examined in patients with and those without AYI (positive abdominal yeast cultures during [re]laparotomy). A variant MBL genotype was found in 53% of patients with AYI and 38% of those without AYI (P = 0.18). A significantly higher proportion of variant patients had an AYI during early peritonitis (during first laparotomy) than WT patients (39% versus 16%, respectively; P = 0.012). Patients with AYI had lower MBL levels than did patients without AYI (0.16 microg/ml [0.0 to 0.65 microg/ml] versus 0.65 microg/ml (0.19 to 1.95 microg/ml); P = 0.007). Intensity of colonization (odds ratio [OR], 1.1; 95% confidence interval [CI], 1.0 to 1.1), MBL plasma concentrations of <0.5 microg/ml (OR, 4.5; 95% CI, 1.2 to 16.3), and numbers of relaparotomies (OR, 1.7; 95% CI, 1.0 to 2.8) were independently associated with AYI. In summary, deficient MBL plasma levels were independently associated with the development of AYI in patients with secondary peritonitis and seemed to facilitate early infection.

Abstract
Object
The aims of this study were to present the rationale for and the evolution of a staged, two-procedure paradigm for spinal surgery requiring pedicle screw instrumentation, and to evaluate the feasibility, safety, and efficacy of the technique.
Methods
The rationale for the new algorithm is presented for consideration in the form of unproven hypotheses subject to verification by subsequent studies. The first stage of the two-staged algorithm, performed in an interventional radiology (IR) setting, involves percutaneous placement of either headless pedicle screws or K-wire fragment placeholders of the trajectory for pedicle screws. The second stage, performed days or weeks later, involves open surgical completion of instrumentation placement and other surgical objectives. The techniques for IR percutaneous K-wire fragment and percutaneous screw placement evolved over the duration of the study.
Instrumentation was placed in 126 pedicles in 25 patients. Efficacy was equated to the accuracy of screw placement, which was evaluated using computed tomography (CT). Algorithms incorporating correction for metal artifact were developed to determine deviation of the screws and K-wire fragments from proper position. Over 1500 measurements were made to evaluate K-wire fragment and screw position in the 116 instrumented pedicles for which CT data were available.
Results
Accuracy of placement (relative to both cortical and pedicle breaches or to only pedicle breaches) was 98 to 100% for K-wire fragments, 96 to 98% for screws following K-wire fragments, and 100% for percutaneous screws. The only adverse consequence of pedicle screw placement by this method was one infection that occurred 8 months postoperatively.
Conclusions
The staged, two-procedure paradigm for pedicle screw placement proved, within the limits of this study, to be feasible, safe, and effective; therefore, the unproven rationale behind the new paradigm merits further evaluation in a larger cohort of patients with randomized, matched controls.

Abstract
The ideal cancer therapy not only induces the death of all localized tumour cells without damage to surrounding normal tissue, but also activates a systemic antitumour immunity. High-intensity focused ultrasound (HIFU) has the potential to be such a treatment, as it can non-invasively ablate a targeted tumour below the skin surface, and may subsequently augment host antitumour immunity. In addition to thermal and cavitation effects, which act directly and locally on the tumour, there is increasing evidence linking systemic anti-tumour immune response to HIFU ablation. This may provide micro-metastatic control and long-term tumour resistance for cancer patients. The goal of this article is to review the emerging pre-clinical and clinical results suggesting that HIFU ablation may enhance host anti-tumour immunity, and to discuss its potential mechanisms. It is concluded that the systemic immune response induced by thermal ablation may play an important role in local recurrence and metastasis control after HIFU treatment.

Abstract
Surgery may render patients susceptible to life-threatening complications, including infections and later metastases. Suppression of cell mediated immunity (CMI) and perturbations in the cytokine network were implicated in these outcomes. The current study assessed the effects of various surgeries on a wide array of immune indices, and compared patients' pre-operative immune status to that of control subjects. A total of 81 subjects (controls, moderate and major surgeries) provided up to five daily blood samples. Whole blood procedures were conducted within hours of blood withdrawal, assessing NK cell number and cytotoxicity, and plasma cytokine levels and induced production (IFNgamma, IL-6, IL-10, and IL-12). Our findings indicate that surgery reduced NK cell numbers/ml blood, and independently suppressed NK activity per NK cell and per ml blood. Among other perturbations in the cytokine network, pro-CMI cytokine production (IL-12 and IFNgamma) was reduced by surgery. Surprisingly, plasma levels of IFNgamma and IL-6 increased following surgery, while their in vitro induced production showed opposite effects. Patients awaiting surgery exhibited impaired IL-12 induced production and NK activity/ml, and reduced IFNgamma plasma levels. No significant associations were found between NK cytotoxicity and Th1 cytokines, although these indices showed high correlations with other variables. Overall, our findings indicate that patients exhibit impaired immune functions even before operation, which seem to contribute to the evident post-operative immune suppression. In the peri-operative context, induced cytokine production and plasma cytokines levels reflect different processes. Last, we suggest that peri-operative suppression of NK activity is mediated by neuroendocrine responses rather than Th1 cytokines.

Abstract
BACKGROUND Recent studies have shown that the Th1/Th2 balance shifts toward Th2 dominance in cancer-bearing state or under surgical stress. This study was designed to investigate whether perioperative impaired Th1/Th2 balance is associated with the occurrence of postoperative infection following colorectal cancer surgery. METHODS From 53 patients with colorectal cancer, peripheral blood samples were collected, before surgery, and on the 3rd, 7th, and 14th postoperative days. The proportions of CD4(+) T-helper cells producing intracellular cytokines including interferon-gamma (Th1 cells) and interleukin-4 (Th2 cells) were measured by flow cytometry. The patients were divided into two groups according to the presence (infected group) and absence (noninfected group) of postoperative infection. RESULTS The infected group showed serum hypoalbuminemia and higher frequency of blood transfusion compared with the noninfected group. No significant difference in the proportion of Th1 cells was observed between the two groups. In contrast, the infected group showed significantly higher proportions of Th2 cells than the noninfected group (1.9 +/- 0.9% for noninfected group and 2.8 +/- 1.3% for infected group; P<0.05). Regarding Th1/Th2 ratio, the infected group showed a lower ratio than the noninfected group (14.7 +/- 8.8 for noninfected group and 9.0 +/- 3.2 for infected group; P<0.05). Throughout the postoperative period, the Th1/Th2 ratio in the infected group was significantly lower than that in the noninfected group. CONCLUSIONS This study demonstrated that perioperative Th2 dominance in addition to hypoalbuminemia and blood transfusion is associated with the occurrence of infection following colorectal cancer surgery. These results provide further information that may direct future treatments based on the Th1/Th2 concept focusing on decreasing the risk of postoperative infection.

Abstract
BACKGROUND Perioperative steroid therapy is often used in oesophageal cancer surgery and we evaluate the effect of this therapy on the secretory leukocyte protease inhibitor levels in the lungs (a major antiprotease in the conducting airways) and postoperative course in oesophageal cancer patients. METHODS Twenty-one patients operated on for oesophageal cancer in 2003-2004 were treated with perioperative steroid therapy (250 mg of methylprednisolone intravenously 1 h before the operation). Fifteen consecutive patients operated on in 2002 served as a control group. Secretory leukocyte protease inhibitor in bronchoalveolar lavage fluid and the postoperative course in the two groups were compared. RESULTS The mortality rate was 0% and there was no significant difference in the morbidity rate between the two groups. Days of intubation and systemic inflammatory response syndrome were significantly shorter for the steroid group. The bronchoalveolar lavage fluid secretory leukocyte protease inhibitor level was significantly higher in the steroid group than in the control group on postoperative days 2 and 3. The secretory leukocyte protease inhibitor level on postoperative day 3 was remarkably lower for the patients intubated for > or = 5 days and for those with pulmonary complications. CONCLUSION Perioperative steroid therapy increased the bronchoalveolar lavage fluid secretory leukocyte protease inhibitor level and reduced the days of intubation and systemic inflammatory response syndrome in patients with oesophagectomy.

Abstract
STUDY OBJECTIVE To investigate the effect of tramadol on the production of serum interleukin (IL) 6, IL-10, and IL-2 and soluble (s) IL-2 receptor (R), thereby evaluating its effects on the proinflammatory and anti-inflammatory responses and immune function in cancer patients undergoing conventional pulmonary lobectomy. DESIGN Randomized, double-blinded, placebo-controlled study. SETTING University hospital. PATIENTS Forty ASA physical status I and II adult patients scheduled for conventional pulmonary lobectomy. INTERVENTIONS Patients were randomly divided into 2 groups (n = 20 in each group). Both groups received general anesthesia with enflurane combined with epidural blockade. At 5 minutes before skin incision, patients were given either tramadol 1.5 mg/kg intravenously (IV), followed by a continuous infusion of 0.5 mg/kg per hour until the end of surgery (group I), or IV normal saline (group II). MEASUREMENTS AND MAIN RESULTS Venous blood samples for the measurement of serum cytokine concentrations were taken before anesthesia and at set intervals until 24 hours after operation. Serum levels of IL-6 and IL-10 in both groups were increased significantly during and after operation compared with baseline levels (P < .05). No statistical differences between groups in terms of IL-6 and IL-10 were observed. Levels of IL-2 were elevated significantly at 4 hours after operation in group I as compared with baseline levels (P < .001), whereas they remained low at 4 and 24 hours after operation in group II (P < .01). There were significant increases in levels of sIL-2R at 4 and 24 hours after operation in group II as compared with baseline levels (P < .05) and at 24 hours after operation in group I (P < .01). Levels of IL-2 were higher at 4 and 24 hours after operation in group I than in group II (P < .01). Levels of sIL-2R were lower at 4 hours after operation in group I than in group II (P < .01). CONCLUSIONS IV infusion of tramadol does not seem to alter IL-6/IL-10 cytokine response to pulmonary lobectomy. As tramadol was associated with increased IL-2 and delayed enhancement of sIL-2R in our study, it may attenuate to some extent an impaired immune response in pulmonary lobectomy.

Abstract
BACKGROUND We investigated whether secretory leukocyte protease inhibitor (SLPI) is associated with pulmonary complications after esophagectomy. METHODS We measured serial changes in the SLPI concentration in the bronchoalveolar lavage fluid (BALF) of 34 patients who underwent and examined the relationship between SLPI and postoperative morbidity. RESULTS Fifteen (44%) of 34 patients (high group) had a BALF SLPI concentration >90,000 pg/mL at the end of the surgery (postoperative day [POD] 0). There was no significant difference between the high group and other 19 patients (low group) with respect to age, sex, preoperative comorbid conditions, tumor stage, surgical technique, operating time, or blood loss volume. Days of intubation and pulmonary complication rate were significantly increased in the high group compared with the low group. Logistic regression analysis revealed that the BALF SLPI level on POD 0 was significant for pulmonary complications. CONCLUSIONS Our results indicate that assaying SLPI levels in BALF can be useful for the prediction of pulmonary complications after esophagectomy.

Abstract
BACKGROUND Pulmonary complications remain the major cause of postoperative mortality in patients with esophageal cancer undergoing esophagectomy. It was unclear whether this dismal complication has a genetic predisposition. We therefore investigated the role of an angiotensin-converting enzyme (ACE) insertion/deletion polymorphism in developing these complications. METHODS We conducted a prospective study including 152 patients with esophageal cancer who underwent esophagectomy in National Taiwan University Hospital between 1996 and 2002. The ACE genotype was determined by polymerase chain reaction amplification of leukocyte DNA obtained before surgery. The serum ACE concentration was determined by enzyme-linked immunosorbent assay. RESULTS Thirty-five patients (23%) developed pulmonary complications following esophagectomy. As compared with patients with the I/I and I/D genotypes, those with the D/D genotype had a higher risk for pulmonary complications (adjusted odds ratio [OR], 3.12; 95% confidence interval [CI], 1.01-9.65). The risk was additively enhanced by combination of the ACE D/D genotype with other clinical risk factors (old age, hypoalbuminemia, and poor pulmonary function). The circulating ACE level was also dose-dependently with the presence of ACE D allele. As compared with the patients with circulating ACE less than 200 ng/mL, the patients with circulating ACE of 200 to 400 ng/mL and over 400 ng/mL had ORs (95% CI) of 2.75 (1.12-6.67) and 15.00 (4.3-52.34) to present with ACE D allele, respectively. CONCLUSIONS An ACE insertion/deletion polymorphism might modulate the function of ACE gene and play a role in affecting individual susceptibility to pulmonary injury following esophagectomy in patients of esophageal cancer.
