However, mice with orthotopically inoculated PDAC cells developed liver metastasis upon TRAIL treatment much more frequently (n=13/17) than mice with subcutaneously inoculated PDAC cells (n=1/11) (P < 0.01). Sunitinib clinical trial As a likely driving force for this increased metastasis, a higher TNF-α staining intensity in the o.t. tumors was observed by immunohistochemistry.

These data from a direct side-by-side comparison underline the importance of the proper inoculation site of the PDAC cells. Local invasion and liver metastases are a hallmark of PDAC in the clinic; the o.t. model is clearly superior in reflecting this setting. Moreover, a serious side-effect of a possible new therapeutic compound became obvious only in the o.t.

Burkitt lymphoma (BL) is an aggressive hematologic cancer. This study synthetized the evidence about the efficacy and safety of chemotherapy treatments used in patients with BL using the World Health Organization classification.

A systematic review of interventional studies was performed. A search was carried out in PubMed, Scopus, and Web of Science, with additional manual and gray literature searches. The methodological quality of articles was assessed with the Newcastle-Ottawa scale.

We identified 1358 studies; 9 nonrandomized studies satisfied the eligibility criteria (n=544 patients). The BL epidemiologic variants were sporadic BL (44.5%), endemic BL (47.2%), and immunodeficiency-associated BL (8.3%). Regarding chemotherapy protocols, 4 groups were identified based on CODOX-M/IVAC (n=4), EPOCH (n=1), BFM (n=1), and simplified treatment schemes used in African countries (n=3). Most studies had moderate quality. Empirically and qualitatively, the best options for adults with sporadic BL were 'DA-EPOCH-R' (7-year overall survival [OS], 100%; 95% confidence interval [CI], 82-100), 'HDR+LD into CODOX-M/IVAC' (2-year OS, 84%), and 'RD-CODOX-M/IVAC' (4-year progression-free survival, 92%; 95% CI, 77-100); in pediatric patients, the 'BFM-NHL-90-like' showed promising results (3-year OS, 90%). For immunodeficiency-associated BL, the 'SC-EPOCH-RR' demonstrated a good therapeutic profile (6-year OS, 90%; 95% CI, 60-98). The 'Malawi 2012-2014' (1-year OS, 73%; 95% CI, 61-85) could be the treatment choice in endemic BL (African countries). The main adverse events were hematologic.

Selecting chemotherapy protocols for BL should be grounded in its epidemiologic variants. Further studies with greater methodological quality are needed to strengthen the evidence.

Eligible studies reporting diagnostic accuracy of pretreatment FDG-PET(CT) scan in immunocompetent adults with PCNSL were identified through systematic literature search. Data on diagnostic performance from individual studies was summarized in a 2 × 2 table classifying patients as true positives, true negatives, false positives, and false negatives using histopathologic diagnosis as reference standard. Random-effects model was used to calculate weighted-mean pooled sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic odds ratio with 95% confidence intervals (95% CI). Twenty-nine primary studies involving 967 patients were included. Weighted-mean pooled sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic odds ratio was 87% (95% CI, 83%-90%), 85% (95% CI, 81%-88%), 84% (95% CI, 81%-88%), 87% (95% CI, 84%-90%), and 29.78 (95% CI, 18.34-48.35), respectively, demonstrating acceptably high diagnostic accuracy of pretreatment FDG-PET(CT) scan in immunocompetent patients with PCNSL.
Non-small cell lung cancer elevates serum carcinoembryonic antigen (CEA). CEA determinations are not recommended currently. This study aims to identify the correlation between reducing serum CEA levels with progression-free survival (PFS) and overall survival.

This study assessed at baseline and in every scheduled visit serum CEA levels throughout first-line therapy. A sensitivity and specificity analysis identified the best cut-off point and correlated it with progression-free survival and overall survival. Multivariate Cox proportional hazard models were conducted.

We assessed 748 patients with elevated serum CEA levels at diagnosis. A ≥20% decrease from baseline was associated with a 2-fold median survival compared with patients with lower decreases (20.5 months vs 9.1 months; hazard ratio, 0.53; 95% confidence interval, 0.44 to -0.64; P < .001). CEA sensitivity and specificity to predict survival was 79.8% and 59.8%, respectively. A ≥10% decrease in CEA concentrations was associated with longer pognosis.With the increasing popularity of robotic surgery, arise a unique set of challenges. In-order to minimise the risk and optimise patient safety, teams need to anticipate these, plan and train to improve familiarity with the nuances of robotic surgery. Human factors and simulation training (ST) are now an integral part of surgery and we have extended these principles to our robotic practice. From our experience with emergencies and a thorough debrief, we have realised the importance of an emergency safety protocol (ESP) for the undocking of the robot, and how training with the correct systems in place optimises our non-technical skills and improves our efficiency. This protocol is used across all robotic specialties allowing for clear communication, situational awareness and role clarity, thereby reducing errors in a high-pressured environment. We aim to share our protocol, highlight the importance of ST and show that coupling of the ESP with ST, including addressing a disrupted power supply and how to avoid the resulting loss of image capture, is where our paper contributes to the current literature. There is a paucity in the literature regarding emergency undocking, and also techniques for avoiding power interruptions, for which we utilise the Uninterruptible Power Supply (UPS) system. By sharing experiences and systems used, we create an opportunity that will result in a culture of shared learning in the robotic community, thereby encouraging other robotic teams to review their protocols and training practices and adapt as necessary.
