1.  The Positive Effects of One-Hour Intravenous Administration of Bortezomib on Peripheral Neuropathy in Multiple Myeloma Patients 
BioMed Research International  2014;2014:237698.
Bortezomib-induced peripheral neuropathy (BiPN) in multiple myeloma (MM) patients is a common and serious side effect. Currently, it has been reported that subcutaneous (SC) administration of bortezomib decreases the incidence of BiPN as compared to standard intravenous (IV) bolus injection without any differences in efficacy. However, there are reports of severe injection site reaction following SC administration of bortezomib. The aim of this study was to evaluate the response rate and incidence of BiPN following one-hour IV infusion of bortezomib. The data was retrospectively collected from MM patients who had been treated with IV administration of bortezomib for one hour. Twenty-three patients were evaluated (median age 72 years, 13 males). The median number of treatment cycles was 5 (range 2–10). The cumulative bortezomib dose was 26.0 mg/m2 (14.3–66.3) and percent of actual per expected cumulative dose was 90% (50–100). The overall response (complete response plus partial response) rate was 65%. The incidence of BiPN was 57% (n = 13) and incidence of severe neuropathy was 4% (n = 1). One-hour IV infusion of bortezomib was an effective regimen for MM with reduced incidence of severe BiPN. This route of administration of bortezomib could be an alternative mode of delivery for patients with severe injection site reactions following SC administration.

2.  Modifiers of TGF-β1 effector function as novel therapeutic targets of pulmonary fibrosis 
Pulmonary fibrosis is a fatal progressive disease with no effective therapy. Transforming growth factor (TGF)-β1 has long been regarded as a central mediator of tissue fibrosis that involves multiple organs including skin, liver, kidney, and lung. Thus, TGF-β1 and its signaling pathways have been attractive therapeutic targets for the development of antifibrotic drugs. However, the essential biological functions of TGF-β1 in maintaining normal immune and cellular homeostasis significantly limit the effectiveness of TGF-β1-directed therapeutic approaches. Thus, targeting downstream mediators or signaling molecules of TGF-β1 could be an alternative approach that selectively inhibits TGF-β1-stimulated fibrotic tissue response while preserving major physiological function of TGF-β1. Recent studies from our laboratory revealed that TGF-β1 crosstalk with epidermal growth factor receptor (EGFR) signaling by induction of amphiregulin, a ligand of EGFR, plays a critical role in the development or progression of pulmonary fibrosis. In addition, chitotriosidase, a true chitinase in humans, has been identified to have modulating capacity of TGF-β1 signaling as a new biomarker and therapeutic target of scleroderma-associated pulmonary fibrosis. These newly identified modifiers of TGF-β1 effector function significantly enhance the effectiveness and flexibility in targeting pulmonary fibrosis in which TGF-β1 plays a significant role.

3.  A Phase II Study to Evaluate the Efficacy of Ramosetron, Aprepitant, and Dexamethasone in Preventing Cisplatin-Induced Nausea and Vomiting in Chemotherapy-Naïve Cancer Patients 
Combination therapy with aprepitant, serotonin receptor antagonist, and steroids improves the complete response rate of both acute and delayed chemotherapy-induced nausea and vomiting (CINV). However, it is not known whether ramosetron is suitable for administration in combination with aprepitant. Therefore, we conducted a multicenter, open-label, prospective, phase II study in order to assess the efficacy and tolerability of combination therapy with ramosetron, aprepitant, and dexamethasone (RAD) for prevention of cisplatin-based CINV in chemotherapy-naïve patients with solid cancers.
Materials and Methods
Forty-one patients with various solid cancers (31 male and 10 female; median age, 59 years) who received treatment with highly emetogenic chemotherapy (median cisplatin dose, 70 mg/m2; range 50 to 75 mg/m2) were enrolled in this study. Oral aprepitant (125 mg on day 1; 80 mg on days 2 and 3), intravenous ramosetron (0.6 mg on day 1), and oral dexamethasone (12 mg on day 1; 8 mg on days 2-4) were administered for prevention of CINV.
The complete response (no emesisand retching and no rescue medication) rate was 94.9% in the acute period (24 hours post-chemotherapy), 92.3% in the delayed period (24-120 hours post-chemotherapy), and 92.3% in the overall period (0-120 hours). The absolute complete response (complete response plus no nausea) rate was 74.4% in the acute period, 51.3% in the delayed period, and 46.2% in the overall period. There were no grade 3 or 4 toxicities related to these antiemetic combinations.
RAD regimen is a safe and effective antiemetic treatment for prevention of CINV in patients receiving highly emetogenic chemotherapy.

4.  Phase I trial of capecitabine plus everolimus (RAD001) in patients with previously treated metastatic gastric cancer 
Everolimus is a novel inhibitor of the mammalian target of rapamycin pathway, which is aberrantly activated in cancer cell. We conducted a phase I study of capecitabine plus everolimus (RAD001) in refractory gastric cancer patients.
Patients with metastatic gastric cancer and progression after prior chemotherapy were eligible. Four dose levels were planned as follows: Level 1, 5 mg bid/day of everolimus (D1-D21) and 500 mg/m2 bid/day of capecitabine (D1-14); Level 2, 5 mg bid/day of everolimus (D1-D21) and 750 mg/m2 bid/day of capecitabine (D1-14); Level 3, 5 mg bid/day of everolimus (D1-D21) and 1000 mg/m2 bid/day of capecitabine (D1-14); and Level 4, 10 mg bid/day of everolimus (D1-D21) and 1000 mg/m2 bid/day of capecitabine (D1-14). Treatment was repeated every 3 weeks until disease progression, patient refusal, or any serious adverse event.
Fifteen patients were enrolled in this study between November 2009 and April 2010. Fifteen patients were enrolled (median age, 50 years; men, 9). Six patients had received two previous chemotherapy regimens; six patients had three previous chemotherapy regimens before the study treatment. Thus, the majority of patients were heavily pretreated. The dose-limiting toxicities were grade 3 infection, grade 3 mucositis, and grade 3 hyperglycemia and hyponatremia. After a median follow-up duration of 5.6 months (range, 2.3–8.1 months), median PFS was 1.8 months (95% CI, 0.8–2.8 months). The maximum best change observed was a 28.7% decrease in sum of longest diameters when compared with baseline.
The combination of capecitabine and everolimus showed satisfactory toxicity profile and modest clinical benefit in patients with refractory gastric cancer. The recommended dose of capecitabine and everolimus was 650 mg/m2 twice daily and 5 mg twice daily, respectively.

5.  Primary CNS lymphoma other than DLBCL: a descriptive analysis of clinical features and treatment outcomes 
Annals of Hematology  2011;90(12):1391-1398.
Diffuse large B-cell lymphoma (DLBCL) constitutes most primary central nervous system (CNS) lymphoma (PCNSL), whereas T-cell, low-grade and Burkitt’s lymphomas (BL) are rarely encountered. Due to the paucity of cases, little is known about the clinical features and treatment outcomes of PCNSL other than DLBCL. The objective of this study was to describe the clinical characteristics and outcomes for patients with PCNSL other than DLBCL. Fifteen patients, newly diagnosed with PCNSLs other than DLBCL between 2000 and 2010, were included. The male to female ratio was 0.67:1 with a median age of diagnosis of 31 years (range 18–59). Pathologic distributions were as follows: peripheral T-cell lymphoma (PTCL; n = 7), marginal zone B-cell lymphoma (MZBCL; n = 1), lymphoplasmacytic lymphoma (LPL; n = 2), Burkitt’s lymphoma (n = 1), other unspecified (T-cell lineage, n = 2; B-cell lineage, n = 2). Thirteen patients (87%) showed Eastern Cooperative Oncology Group performance score (ECOG PS) 1–2. The remaining two were one PTCL patient and one Burkitt’s lymphoma patient. Of the nine patients with T-cell lymphoma, five (56%) had multifocal lesions, and one (20%) with LPL of the five patients with B-cell lymphoma showed a single lesion. Leptomeningeal lymphomatosis was identified in two patients (one with Burkitt’s lymphoma and one with unspecified B-cell lymphoma). Two patients (22%) with T-cell lymphoma died 7.7 and 23.3 months later, respectively, due to disease progression, despite HD-MTX-based therapy. Six patients with T-cell lymphoma (6/9, 66.7%) and four patients with low-grade B-cell lymphoma (4/5, 80%) achieved complete response and have survived without relapse (Table 3). One patient with Burkitt’s lymphoma showed poor clinical features with ECOG PS 3, deep structure, multifocal, and leptomeningeal lymphomatosis, and died 7.6 months after the initiation of treatment. In comparison with previously reported DLBCLs (median OS 6.4 years, 95% CI 3.7–9.1 years), T-cell lymphoma showed equivocal or favorable clinical outcomes and low-grade B-cell lymphomas, such as MZBCL and LPL, had a good prognosis. However, primary CNS Burkitt’s lymphoma presented poor clinical outcomes and showed a comparatively aggressive clinical course. In conclusion, primary CNS lymphoma other than DLBCL occurred more in younger patients and showed a generally good prognosis, except for Burkitt’s lymphoma. Further research on treatment strategies for Burkitt’s lymphoma is needed.
