ABSTRACT
PURPOSE: First-line therapy options in advanced cholangiocarcinoma (CCA) are based on the ABC-02 trial regimen (gemcitabine/cisplatin [G/C]). The NIFE trial examined nanoliposomal irinotecan/fluorouracil/leucovorin (nal-IRI/FU/LV) as alternative first-line therapy in advanced CCA. METHODS: NIFE is a prospective, open-label, randomized, multicenter phase II study that aimed at detecting efficacy comparable with the standard treatment. Patients with advanced CCA were randomly assigned (1:1) to receive nal-IRI/FU/LV (arm A) or G/C (arm B). Stratification parameters were intrahepatic versus extrahepatic CCA, sex, and Eastern Cooperative Oncology Group (ECOG; 0/1). Arm A was designed as a Simon's optimal two-stage design and arm B served as a randomized control group. The primary goal was to exclude an inferior progression-free survival (PFS) at 4 months of only 40%, while assuming a rate of 60% on G/C population. RESULTS: Between 2018 and 2020, overall 91 patients were randomly assigned to receive nal-IRI/FU/LV (n = 49) or G/C (n = 42). The NIFE trial formally met its primary end point with a 4-month PFS rate of 51% in patients receiving nal-IRI/FU/LV. The median PFS was 6 months (2.4-9.6) in arm A and 6.9 months (2.5-7.9) in arm B. Median overall survival (OS) was 15.9 months (10.6-20.3) in arm A and 13.6 months (6.5-17.7) in arm B. The exploratory comparison of study arms suggested a numerical but statistically not significant advantage for nal-IRI/FU/LV (hazard ratio for PFS, 0.85 [95% CI, 0.53 to 1.38] and for OS, 0.94 [95% CI, 0.58 to 1.50]). Analysis for stratification parameters revealed no differences for sex and ECOG, but for tumor localization. The objective response rate was 24.5% with nal-IRI/FU/LV and 11.9% with G/C. No unexpected toxicities occurred. AEs related to nal-IRI/FU/LV were mainly GI and to G/C hematologic. CONCLUSION: Treatment of advanced CCA with nal-IRI/FU/LV demonstrated efficacy in first-line therapy without new safety findings and merits further validation.
ABSTRACT
A randomized inter-group trial comparing more intensive treatment strategies to a common standard arm 3 + 7 (CSA) was conducted in patients with non-M3 AML. Untreated patients ≥ 60 years were allocated to the CSA (n = 132) or to the study group arms (n = 1154) of the AMLCG (TAD/HAM versus HAM/HAM ± G-CSF followed by TAD and maintenance) and the OSHO (intermediate-dose ara-C/mitoxantrone followed by ara-C/mitoxantrone). Median age of the 1147 eligible patients was 69 (range 60-87) years. CR/CRi status at 90 days was not significantly different between the CSA (54% (95%CI: 45-64)) and the study group arms (53% (95%CI: 47-60) and 59% (95%CI: 58-63)). The five-year event-free survival (EFS) probability (primary endpoint) was 6.2% (95%CI: 2.7-14.0) in the CSA, 7.6% (95%CI: 4.5-12.8) in study group A and 11.1% (95%CI: 9.0-13.7) in B. The 5-year OS was 17.2% (95%CI: 11.0-26.9), 17.0% (95%CI: 2.0-23.9), and 19.5% (95%CI: 16.7-22.8) in CSA, study group A and B, respectively. Neither study group differed significantly from the CSA regarding EFS, OS, or relapse-free survival. In multivariate analyses, allocation to the treatment strategy was not significantly associated with the time-to-event endpoints. The evaluation of more intensive treatment strategies did not show clinically relevant outcome differences when compared to CSA.

PURPOSE: Advanced pancreatic cancer (APC), in addition to its high mortality, accounts for the highest rates of venous thromboembolic events (VTEs). Enoxaparin, a low-molecular weight heparin, is effective in prevention and treatment of VTEs. Some small studies have indicated that this benefit might extend to patients with cancer. PATIENTS AND METHODS: Patients with histologically proven APC were randomly assigned to ambulant first-line chemotherapy and prophylactic use of enoxaparin or chemotherapy alone to investigate the probable reduction in symptomatic VTEs and the impact on survival. RESULTS: A total of 312 patients were recruited as one of the protocol end points was reached. Within the first 3 months, the numbers of symptomatic VTEs were as follows: 15 of 152 patients in the observation group and two of 160 patients in the enoxaparin group (hazard ratio [HR], 0.12; 95% CI, 0.03 to 0.52; χ(2) P = .001). The numbers of major bleeding events were as follows: five of 152 patients in the observation arm and seven of 160 patients in the enoxaparin arm (HR, 1.4; 95% CI, 0.35 to 3.72; χ(2) P = 1.0). Overall cumulative incidence rates of symptomatic VTEs were 15.1% (observation) and 6.4% (enoxaparin; HR, 0.40; 95% CI, 0.19 to 0.83; P = .01). Progression-free (HR, 1.06; 95% CI, 0.84 to 1.32; P = .64) and overall survival (HR, 1.01; 95% CI, 0.87 to 1.38; P = .44) did not differ between groups. CONCLUSION: This study demonstrates the high efficacy and feasibility of primary pharmacologic prevention of symptomatic VTEs in outpatients with APC. Treatment efficacy was not affected by simultaneous treatment with enoxaparin in this trial setting.

BACKGROUND: Advanced pancreatic cancer, in addition to its high mortality, is characterized by one of the highest rates of venous thromboembolic events (VTE) as compared to other types of cancer. Enoxaparin, a low molecular weight heparin (LMWH), has proven to be effective for the prevention and treatment of VTE in surgical and general medical patients. Results of some small studies suggest that this benefit might extend to patients with cancer, however, enoxaparin is not currently indicated for this use. This phase IIb study was designed to analyze the efficacy of enoxaparin in patients with locally advanced or metastatic pancreatic cancer undergoing systemic chemotherapy. METHODS: The aim of this prospective multicenter trial is to compare concomitant treatment with enoxaparin to no anticoagulation in 540 patients. Primary endpoint is the incidence of clinically relevant VTE (symptomatic deep venous thrombosis (DVT) of the leg and/or pelvic and/or pulmonary embolism (PE)) within the first 3 months. Secondary endpoints include the incidence of symptomatic and asymptomatic VTE after 6, 9 and 12 months as well as remission at 3, 6, 9 and 12 months, overall survival and bleeding. TRIAL REGISTRATION: isrctn.org identifier CCT-NAPN-16752, controlled-trials.com identifier: ISRCTN02140505. RESULTS: An interim analysis for safety performed after inclusion of 152 patients revealed no increased risk of bleeding (5 pts vs. 6 pts, Chi2: 0.763). CONCLUSION: PROSPECT is a pivotal study in elucidating the role of low molecular weight heparins in advanced pancreatic cancer. Its results will lead to a new understanding of the role of heparins in the prevention of venous thromboembolism and of their effect on survival, remission rates and toxicity of chemotherapeutic regimens.

BACKGROUND: Visceral leishmaniasis is a rare imported infectious disease in Germany. Approximately ten to 30 cases are recorded annually. The classic symptoms are often misinterpreted as lymphoma of the spleen. CASE REPORT: A 46-year-old patient presented with fever, malaise, night sweats, pancytopenia, and splenomegaly 8 months after a 2-week trip to Majorca Island (Spain). Bone marrow biopsy showed no evidence of malignant lymphoma. Serology confirmed the suspected clinical diagnosis of visceral leishmaniasis. Cytology and polymerase chain reaction from bone marrow aspirate were positive for Leishmania infantum. Treatment with liposomal amphotericin B was initiated and led to complete recovery. CONCLUSION: Visceral leishmaniasis is an important differential diagnosis for the clinical triad of fever, pancytopenia, and splenomegaly. An accurate travel history is therefore of paramount importance. Without treatment, the case fatality rate is high. A complete recovery is usually achieved with adequate therapy (liposomal amphotericin B, miltefosine).
