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). 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) sca
