  • As previously reported, an immunoglobulin M (IgM) monoclonal antibody (MAb) B6.1, specific for a cell wall B-l,2-mannotriose, was protective against vaginal infection due to Candida albicans when mice were treated with the antibody. In this study, the role of neutrophil was examined in the protective effect of MAb B6.1 against vaginal infection. To deplete neutrophils, mice were given intravenously rat anti-mouse neutrophile MAb RB6-8C5 prior to intraperitoneal administration of MAb B6.1 to these mice. The mice were examined for antibody in their reproductive tract. By an ELISA, MAb B6.1 was found in the vaginal homogenates, but no antibody was detected in vaginal lavage materials. The neutropenia was induced by a single dose of the anti-neutrophil antibody, but lymphocytes were also partially depleted. The protective effect of MAb B6.1 was decreased when mice pretreated with MAb RB6-8C5 were given the anti-Candida antibody before challenge with C. albicans yeast cells intravaginally. These results show that neutrophils are involved in the MAb B6.1 protection against Candida vaginal infection.

  • Background: Multiple primary malignancies (MPM) have become increasingly prevalent worldwide. This investigation was aimed at establishing the clinicopathological characteristics of MPM patients and evaluating the impact of the living environment on MPM in the Taiwanese population. Materials and Methods: From January 2009 to December 2013, a total of 8,268 cancer patients were identified in our institutional center. Of these, 125 were diagnosed as MPM and thus enrolled. Data for clinicopathological features and treatment approaches for these MPM patients living in urban or suburb zone were obtained. Findings for the air pollution status in Taiwan were also collected. Results: The most common cancer match of MPM was esophageal cancer with hypopharyngeal cancer (12.8%), followed by colorectal cancer with gastric cancer (6.4%) and colorectal cancer with breast cancer (5.6%). The air quality was significantly worse in the urban than in the suburban zone and there was a remarkably higher portion of MPM patients in the urban zone suffering from grade III and IV post-chemotherapeutic neutropenia (30.8% vs 15.1%, P=0.036). Conclusions: The tumor frequency and site distribution should be taken into the clinical evaluation because there is a relatively high risk of developing MPM. This study also highlighted the potential influence of environmental factors on post-chemotherapeutic neutropenia for patients with MPM.

  • Backgrounds : Head and neck cancer is one of the most prevalent cancers in the world. It tends to remain localized at the primary site and regional lymph nodes, but if distant metastasis occurs, it has a poor prognosis. This study was performed to evaluate the prevalence of distant metastasis and to determine the risk factor in locally advanced head and neck cancer after induction chemotherapy followed locoregional control therapy. Methods : A retrospective review was performed in 420 patients with locally advanced head and neck cancer who treated with induction chemotherapy followed locoregional control therapy from January 2001 to December 2010. Among them, 31 patients who had distant metastasis as first relapse within 2 years after termination of therapy were analyzed for clinical features and the risk factors of distant metastasis. Results : The overall incidence of distant metastasis was 7.3%. The bone, lung, and liver were the most frequent metastatic organs. In univariate analysis, nodal stage, nasopharyngeal cancer, laryngeal cancer, G3/G4 neutropenia during induction chemotherapy, and concurrent chemoradiotherapy were the influencing factors for distant metastasis. In multivariate analysis, advanced N stage and nasopharynx were the risk factors of distant metastasis, and grade 3/4 neutropenia during induction chemotherapy was considered to decrease distant metastasis. Conclusion : This study suggests that the advanced N stage is the risk factor of distant metastasis and Grade 3/4 neutropenia during induction chemotherapy can be beneficial against distant metastasis in locally advanced head and neck cancer patients treated with induction chemotherapy followed locoregional control therapy.

  • Background: Our aim was to conduct a meta-analysis to compare the efficacy and safety of pemetrexed and docetaxel for non-small cell lung cancer (NSCLC). Materials and Methods: We systematically searched the Cochrane Library, PubMed, Embase, China Biology Medicine Database for randomized controlled trials (RCTs) comparing the efficacy and toxicities of pemetrexed versus docetaxel as a treatment for advanced NSCLC. We limited the languages to English and Chinese. Two reviewers independently screened articles to identify eligible trials according to the inclusion and exclusion criteria and assessed the methodological quality of included trials, and then extracted data. The meta-analysis was performed using STATA12.0. Results: Six RCTs involving 1,414 patients were identified. We found that there was no statistically significant differences in overall response rate, survival time, progression-free survival, disease control rate, and 1-2yr survival rate (p>0.050) but it is worthy of mention that patients in the pemetrexed arms had significantly higher 3-yr survival rate (P=0.002). With regard to the grade 3 or 4 hematological toxicity, compared with docetaxel, pemetrexed led to lower rate of grade 3-4 febrile neutropenia, neutropenia, and leukocyts toxicity (p<0.001). There was no significant difference in anemia between the two arms (p=0.08). In addition, pemetrexed led to higher rate of grade 3-4 thrombocytopenia toxicity (p=0.03). As for the non-hematological toxicities, compared with docetaxel, pemetrexed group had lower rate of grade 3-4 diarrhea and alopecia. Conclusions: Pemetrexed was almost as effective as docetaxel in patients with advanced NSCLC. At the same time, pemetrexed might increase the 3-yr survival rate. As for safety, pemetrexed led to lower rate of grade 3-4 febrile neutropenia, neutropenia, leukocytes, diarrhea and alopecia toxicity. However, it was associated with a higher rate of grade 3-4 thrombocytopenia.

  • Inherited bone marrow failure syndrome (IBMFS) encompasses a heterogeneous and complex group of genetic disorders characterized by physical malformations, insufficient blood cell production, and increased risk of malignancies. They often have substantial phenotype overlap, and therefore, genotyping is often a critical means of establishing a diagnosis. Current advances in the field of IBMFSs have identified multiple genes associated with IBMFSs and their pathways: genes involved in ribosome biogenesis, such as those associated with Diamond-Blackfan anemia and Shwachman-Diamond syndrome; genes involved in telomere maintenance, such as dyskeratosis congenita genes; genes encoding neutrophil elastase or neutrophil adhesion and mobility associated with severe congenital neutropenia; and genes involved in DNA recombination repair, such as those associated with Fanconi anemia. Early and adequate genetic diagnosis is required for proper management and follow-up in clinical practice. Recent advances using new molecular technologies, including next generation sequencing (NGS), have helped identify new candidate genes associated with the development of bone marrow failure. Targeted NGS using panels of large numbers of genes is rapidly gaining potential for use as a cost-effective diagnostic tool for the identification of mutations in newly diagnosed patients. In this review, we have described recent insights into IBMFS and how they are advancing our understanding of the disease's pathophysiology; we have also discussed the possible implications they will have in clinical practice for Korean patients.

  • Objectives : Contradictions for Oncology acupuncture were searched and reviewed to establish fundamentals for the appropriate contraindication guideline. Methods : In order to search contraindications for oncology acupuncture, domestic journals, books and online database of Pubmed were searched using the terms, cancer, tumor, acupuncture, safety, contraindications and guideline were below. Results : We found 7 papers and 1 book by the above methods. We reviewed and suggested the contraindications. Contraindications for oncology acupuncture are neutropenia (absolute neutrophil count : ANC less than $500/mm^3$), thrombocytopenia (platelets less than $50,000/mm^3$), anticoagulant use, spinal instability, tumour nodule, lymphedema, prosthesis, intracranial deficits, confused patients, significant arrhythmia, patient refusal to treatment, severe neurotic patients and intracardiac defribillator. Contraindications for using semi-permanent needles are neutropenia (ANC less than $500/mm^3$), splenectomy, valvular heart disease, B, C hepatitis and keloids. Conclusions : Acupuncture for cancer patients pose significant risks but these guidelines are proposed in the hopes of providing certain boundaries in practicing oncology acupuncture. A more systematic and rigorous research is needed to establish a more reliable oncology acupuncture guidelines.
