Real-World Analysis of the Correlation between Overall Survival and Progression-Free Survival in Advanced Pancreatic Cancer: Results of NAPOLEON-1 and 2 Studies.

Introduction: Fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) improve overall survival (OS) and progression-free survival (PFS) in patients with pancreatic cancer, compared with gemcitabine (GEM). However, whether PFS is a surrogate marker of OS in pancreatic cancer chemotherapy focusing on FOLFIRINOX or GEM plus nab-paclitaxel remains unknown. We aimed to verify whether PFS can be a surrogate marker of OS in prognosis prediction.

A multicenter retrospective observational NAPOLEON2 study of nanoliposomal irinotecan with fluorouracil and folinic acid in patients with unresectable pancreatic cancer.

Nanoliposomal irinotecan with fluorouracil and folinic acid (NFF) is a standard regimen after gemcitabine-based therapy for patients with unresectable or recurrent pancreatic cancer. However, there are limited clinical data on its efficacy and safety in the real-world. We therefore initiated a retrospective and prospective observational study (NAPOLEON-2).

Feasibility of an intensified myeloablative conditioning regimen consisting of busulfan, fludarabine, cytarabine, and total body irradiation before single cord blood transplantation in elderly patients.

The optimal conditioning regimen for stem cell transplantation in elderly patients remains to be established. We developed a novel preparative regimen using fludarabine 180 mg/m, intravenous busulfan 12.8 mg/m, cytarabine 8 g/m, and 4-Gy total body irradiation before cord blood transplantation (CBT) in patients older than 55 years with various hematological malignancies.

Intravenous itraconazole compared with liposomal amphotericin B as empirical antifungal therapy in patients with neutropaenia and persistent fever.

Background: Fungal infections are a major complication of neutropaenia following chemotherapy. Their early diagnosis is difficult, and empirical antifungal treatment is widely used, and uses of less toxic drugs that reduce breakthrough infection are required.

Objective: We conducted a multicentre, open-label, randomised, non-inferiority trial to compare the safety and efficacy of intravenous itraconazole (ivITCZ) and liposomal amphotericin B (LAmB) as empirical antifungal therapy in patients with haematological malignancies with neutropaenia and persistent fever.

A phase II study of bortezomib in patients with relapsed or refractory aggressive adult T-cell leukemia/lymphoma.

Adult T-cell leukemia/lymphoma (ATL) is a malignancy of peripheral T-lymphocytes with a poor prognosis. This multicenter, two-stage, single-arm, phase II study assessed the efficacy and safety of bortezomib in patients with relapsed/refractory ATL who received at least one regimen of chemotherapy. The primary endpoint was the best overall response rate (ORR), and secondary endpoints included safety, the best response by lesions, and progression-free survival (PFS).

Revisiting human IL-12Rβ1 deficiency: a survey of 141 patients from 30 countries.

Interleukin-12 receptor β1 (IL-12Rβ1) deficiency is the most common form of Mendelian susceptibility to mycobacterial disease (MSMD). We undertook an international survey of 141 patients from 102 kindreds in 30 countries. Among 102 probands, the first infection occurred at a mean age of 2.

[Serum sickness induced by rituximab infusion; report of two cases with hematological malignancies].

We report 2 cases of serum sickness after rituximab infusion. Case 1 is a patient with Waldenström's macroglobulinemia, and case 2 is a patient with marginal-zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) type and Sjögren's syndrome. Both patients had polyclonal hypergammaglobulinemia, were treated with rituximab monotherapy, developed serum sickness between 9 and 17 days after the first rituximab infusion, developed fever and arthralgia, and improved soon after corticosteroid treatment.

A potential link between alternative splicing of the NBS1 gene and DNA damage/environmental stress.

NBS1 forms a multimetric complex with MRE11/RAD50, which acts as the sensor of DNA double-strand breaks (DSBs). The mechanisms controlling the expression of NBS1 remain largely unknown. Here we show that NBS1 is transcribed as both a wild-type and an alternatively spliced form exhibiting a premature stop codon in an alternative 50-bp exon in intron 2.

Identification of aberrantly methylated genes in association with adult T-cell leukemia.

In this study, we identified 53 aberrantly hypermethylated DNA sequences in adult T-cell leukemia (ATL) cells using methylated CpG island amplification/representational difference analysis method. We also observed a proportionate increase in the methylation density of these regions with disease progression. Seven genes, which were expressed in normal T cells, but suppressed in ATL cells, were identified near the hypermethylated regions.

Mechanism of hypercalcemia in adult T-cell leukemia: overexpression of receptor activator of nuclear factor kappaB ligand on adult T-cell leukemia cells.

Hypercalcemia is one of the most frequent and serious complications in patients with adult T-cell leukemia (ATL) and is due to marked bone resorption by accumulation of osteoclasts (OCLs). Although several cytokines such as interleukin 1 and parathyroid hormone-related protein are thought to be involved in the development of high serum Ca(++) levels, its precise underlying mechanism remains unknown. This study analyzed the expression of various genes that are thought to regulate serum Ca(++) levels in ATL and showed that the overexpression of the receptor activator of nuclear factor kappaB (RANK) ligand gene correlated with hypercalcemia.
