Background: Mantle cell lymphoma (MCL) is a B cell malignancy that can be aggressive and with a poor prognosis; the clinical course is heterogeneous. The epidemiology of MCL in Asia is not well documented but appears to comprise 2-6% of all lymphoma cases based on available data, with variation observed between countries. Although international guidelines are available for the treatment of MCL, there is a lack of published data or guidance on the clinical characteristics and management of MCL in patient populations from Asia. This paper aims to review the available treatment and, where clinical gaps exist, provide expert consensus from the Asian Lymphoma Study Group (ALSG) on appropriate MCL management in Asia. Body: Management strategies for MCL are patient-and disease stage-specific and aim to achieve balance between efficacy outcomes and toxicity. For asymptomatic patients with clearly indolent disease, observation may be an appropriate strategy. For stage I/II disease, following international guidelines is appropriate, which include either a short course of conventional chemotherapy followed by consolidated radiotherapy, less aggressive chemotherapy regimens, or a combination of these approaches. For advanced disease, the approach is based on the age and fitness of the patient. For young, fit patients, the current practice for induction therapy differs across Asia, with cytarabine having an important role in this setting. Hematopoietic stem cell transplantation (HSCT) may be justified in selected patients because of the high relapse risk. In elderly patients, specific chemoimmunotherapy regimens available in each country/region are a treatment option. For maintenance therapy after first-line treatment, the choice of approach should be individualized, with cost being an important consideration within Asia. For relapsed/ refractory disease, ibrutinib should be considered as well as other follow-on compounds, if available. Conclusion: Asian patient-specific data for the treatment of MCL are lacking, and the availability of treatment options differs between country/region within Asia. Therefore, there is no clear one-size-fits-all approach and further investigation on the most appropriate sequence of treatment that should be considered for this heterogeneous disease.

Gram-negative bacilli, especially the glucose-non-fermenting pathogens, tend to be the major microorganisms that account for port-related infections, and the infections run a benign course, even those developed in septicemia.

In order to analyze the incidence of thrombophilia in southern Taiwan, we studied the prevalence of antithrombin (AT), protein C (PC), and protein S (PS) deficiencies, the prevalence of factor V Leiden mutation, and the presence of acquired lupus anticoagulant (LA) and anticardiolipin antibody (ACA) in 56 patients < or =65 years old with deep venous thrombosis (DVT). Of 56 patients, 30 were male, 26 female, and the mean age of the patients was 43 years (18-65 years). None had factor V mutation or activated PC resistance; 21 patients (37.5%) showed abnormal results: 4 (7.1%) had AT deficiencies, 6 (10.7%) PC deficiencies, 6 (10.7%) PS deficiencies, 2 (3.6%) a combined PC and PS deficiency, and 3 (5.4%) LA and ACA. Only PC and PS deficiencies were significantly associated with increased risk for the development of thrombosis with an odds ratio of 4.2 (95% confidence interval: 1.2-15.0, P=0.018) and 8.1 (95% confidence interval: 1.6-40.6, P=0.003), respectively. We concluded that the prevalence of heritable thrombophilia (34.0%) in Taiwan is higher than that in Western countries, but that it is lower than previously reported in Hong Kong and Taiwan. We attribute this to selection bias.

Objectives: Patients with non-small-cell lung cancer (NSCLC) and malignant pleural effusion (MPE) are difficult to manage clinically and have a short life expectancy. In this pilot study, we designed a protocol of combined intrapleural (i.p.) and intravenous (i.v.) chemotherapy and pulmonary irradiation to enhance local as well as systemic control of the disease. Methods: From April 1998 to April 2000, 27 patients with NSCLC and symptomatic MPE were eligible for the study. Patients received pre-radiation chemotherapy (cisplatin 60 mg/m² i.p. on day 1; gemcitabine 1,000 mg/m² i.v. on days 1, 8, and 15, q4week × 3) after surgical implantation of i.p. and i.v. port-A, followed by radiotherapy (7,020 cGy/39fr), and, finally, post-radiation chemotherapy (docetaxel 60 mg/m² q3week × 3–6 i.v.). Results: Grade 1/2 nausea/vomiting and impaired renal function were more common from pre-radiation than post-radiation chemotherapy; however, grade 3/4 toxicities from pre-radiation chemotherapy were minimal. Conversely, grade 3/4 leukopenia and grade 1/2 alopecia, diarrhea, elevation of SGOT/SGPT, and sensory impairment were more common following post-radiation chemotherapy. Only two patients experienced recurrence of pleural effusion. The overall response rate was 55% with 7% complete remission, 48% partial remission, 22% stable disease, and 22% progressive disease. The median failure-free and overall survival was 8 and 16 months, respectively. The one-year survival rate was 63% (95% confidence interval, 45–80%). Conclusions: We conclude that the combination of i.p. and i.v. chemotherapy and pulmonary irradiation is feasible and should be tested in a larger clinical trial to determine whether survival can be improved for this cohort of patients.
