Introduction: Accurate assessment of lymph node (LN) involvement with malignancy is critical to staging and management of non-smallcell lung cancer. The goal of this retrospective study was to determine the tumor and imaging characteristics independently associated with malignant involvement of LNs visualized on positron emission tomography/computed tomography (PET/CT). Methods: From 2002 to 2011, 172 patients with newly diagnosed non- small-cell lung cancer underwent PET/CT within 31 days before LN biopsy. Among these patients, 504 anatomically defined, pathologyconfirmed LNs were visualized on PET/CT. Logistic regression analysis was used to determine the associations between nodal involvement with malignancy and several clinical and imaging variables, including tumor histology, tumor grade, LN risk category in relation to the primary tumor location, pathologic findings from additional biopsied LNs, interval between PET/CT and biopsy, primary tumor largest dimension, primary tumor standardized uptake value (SUVmax), LN short-Axis dimension, and LN SUVmax. Results: On univariate analysis, adenocarcinoma histology (p = 0.010), high LN risk category (p < 0.001), larger LN short-Axis dimension (p < 0.001), and higher LN SUVmax (p < 0.001) all correlated with nodal involvement. On multivariate analysis, adenocarcinoma histology (p = 0.003), high LN risk category (p = 0.005), and higher LN SUVmax (p < 0.001) correlated with nodal involvement, whereas LN short-Axis dimension was no longer statistically significant (p = 0.180). A nomogram developed for clinical application based on this analysis had excellent concordance between predicted and observed results (concordance index, 0.95). Conclusion: Adenocarcinoma histology, higher LN SUVmax, and higher LN risk category independently correlate with nodal involvement with malignancy and may be used in a model to accurately predict the risk of a node's involvement with malignancy.

Cell-based therapies, such as adoptive immunotherapy and stem-cell therapy, have received considerable attention as novel therapeutics in oncological research and clinical practice. The development of effective therapeutic strategies using tumor-targeted cells requires the ability to determine in vivo the location, distribution, and long-term viability of the therapeutic cell populations as well as their biological fate with respect to cell activation and differentiation. In conjunction with various noninvasive imaging modalities, cell-labeling methods, such as exogenous labeling or transfection with a reporter gene, allow visualization of labeled cells in vivo in real time, as well as monitoring and quantifying cell accumulation and function. Such cell-tracking methods also have an important role in basic cancer research, where they serve to elucidate novel biological mechanisms. In this Review, we describe the basic principles of cell-tracking methods, explain various approaches to cell tracking, and highlight recent examples for the application of such methods in animals and humans. © 2011 Macmillan Publishers Limited.

BACKGROUND:: The potential benefit of adjuvant hepatic arterial infusional floxuridine (HAI-FUDR) in addition to modern systemic chemotherapy using oxaliplatin or irinotecan remains unknown for patients with resected liver-confined colorectal metastases (CRLM). The principle aim of this study was to compare outcomes in patients receiving modern systemic chemotherapy with or without HAI-FUDR. METHODS:: Between 2000 and 2005, 125 patients underwent resection of CRLM followed by adjuvant HAI-FUDR plus dexamethasone (Dex) and concurrent systemic chemotherapy including oxaliplatin or irinotecan. These patients were compared retrospectively to 125 consecutive patients who received modern systemic chemotherapy alone after liver resection. RESULTS:: The median follow-up for all patients was 43 months. There were no differences in clinical risk score, disease-free interval, size of largest CRLM, number of CRLM, or prehepatectomy CEA level between the 2 groups. Adjuvant HAI-FUDR was associated with an improved overall and liver recurrence-free survival (liver RFS) and disease-specific survival (DSS). For the adjuvant HAI-FUDR group, the 5-year liver RFS, overall RFS, and DSS were 75%, 48%, and 79%, respectively, compared to 55%, 25%, and 55% for the systemic alone group (P < 0.01). On multivariate analysis, adjuvant treatment including HAI-FUDR was independently associated with improved liver RFS (HR = 0.34), overall RFS (HR = 0.65), and DSS (HR = 0.39), P < 0.01. CONCLUSIONS:: Adjuvant HAI-FUDR combined with modern systemic chemotherapy is independently associated with improved survival compared to adjuvant systemic chemotherapy alone. A randomized clinical trial between these 2 regimens is justified. Copyright C © 2011 by Lippincott Williams & Wilkins.

Background Intrahepatic pedicle ligation (IPL) is an alternative to extrahepatic portal dissection (EPD). Although IPL has been well described, concern has arisen over a possible association with increased complication rates. Methods Patients who underwent hemi-hepatectomy during January 1995 to December 2010 were reviewed and the inflow control technique (IPL versus EPD) documented. Patient, tumour, treatment and outcome variables were compared. Results A total of 798 patients underwent hemi-hepatectomy, 568 (71.2%) of the right and 230 (28.8%) of the left liver. In univariate analysis, factors associated with the choice of IPL included surgeon, right hepatectomy, preoperative portal vein embolization, diagnosis of colorectal cancer liver metastasis, and smaller tumour size (P < 0.011). In multivariate analysis, right hepatectomy [versus left: hazard ratio (HR) 3.878, 95% confidence interval (CI) 1.15-13.14; P = 0.029] and smaller tumour size (median of 4.5 cm versus 5.5 cm: HR 0.72, 95% CI 0.59-0.88; P = 0.002) were associated with IPL. Pringle manoeuvre time was longer in IPL procedures (40 min versus 29 min; P < 0.001). Complication rates (49.8% in IPL versus 48.4% in EPD; P = 0.706) were similar in both groups, as was the severity of complications; 17.6% of EPD and 22.3% of IPL patients experienced complications of grade ≥3 (P = 0.225). Conclusions Patients with small tumours undergoing right hepatectomy were more likely to undergo IPL. In selected patients, IPL was not associated with an increased complication rate and thus it should be considered a safe approach. © 2012 International Hepato-Pancreato-Biliary Association.

Purpose To evaluate the safety and efficacy of percutaneous peritoneovenous shunt (PPVS) placement in treating intractable chylous ascites (CA) in patients with cancer. Materials and Methods Data from 28 patients with refractory CA treated with PPVS from April 2001 to June 2015 were reviewed. Demographic characteristics, technical success, efficacy, laboratory values, and complications were recorded. Univariate and multivariate logistic regression analysis was performed. Results Technical success was 100%, and ascites resolved or symptoms were relieved in 92.3% (26 of 28) of patients. In 13 (46%) patients with urologic malignancies, whose ascites had resulted from retroperitoneal lymph node dissection, the ascites resolved, resulting in shunt removal within 128 days ± 84. The shunt provided palliation of symptoms in 13 of the remaining 15 patients (87%) for a mean duration of 198 days ± 214. Serum albumin levels increased significantly (21.4%) after PPVS placement from a mean of 2.98 g/dL ± 0.64 before the procedure to 3.62 g/dL ± 0.83 (P <.001). The complication rate was 37%, including shunt malfunction/occlusion (22%), venous thrombosis (7%), and subclinical disseminated intravascular coagulopathy (DIC) (7%). Smaller venous limb size (11.5 F) and the presence of peritoneal tumor were associated with a higher rate of shunt malfunction (P <.05). No patient developed overt DIC. Conclusions PPVS can safely and effectively treat CA in patients with cancer, resulting in significant improvement in serum albumin in addition to palliation of symptoms. © 2016 SIR.
