Role of geographic characteristics in the spatial cluster detection of cancer: Evidence in South Korea, 1999-2013.

Background: Identification of high-risk areas of cancer, referred to as spatial clusters, can inform targeted policies for cancer control. Although cancer cluster detection could be affected by various geographic characteristics including sociodemographic and environmental factors which impacts could also vary over time, studies accounting for such influence remain limited. This study aims to assess the role of geographic characteristics in the spatial cluster detection for lung and stomach cancer over an extended period.

Split genome-based retroviral replicating vectors achieve efficient gene delivery and therapeutic effect in a human glioblastoma xenograft model.

The murine leukemia virus-based semi-retroviral replicating vectors (MuLV-based sRRV) had been developed to improve safety and transgene capacity for cancer gene therapy. However, despite the apparent advantages of the sRRV, improvements in the in vivo transduction efficiency are still required to deliver therapeutic genes efficiently for clinical use. In this study, we established a gibbon ape leukemia virus (GaLV) envelopepseudotyped semi-replication-competent retrovirus vector system (spRRV) which is composed of two transcomplementing replication-defective retroviral vectors termed MuLV-Gag-Pol and GaLV-Env.

Zanubrutinib monotherapy in relapsed/refractory indolent non-Hodgkin lymphoma.

Outcomes for marginal zone lymphoma (MZL) and follicular lymphoma (FL) remain suboptimal, owing to the limited number of approved agents and the incurable nature of the diseases. BGB-3111-AU-003 was a phase 1/2, open-label, multicenter, single-agent study of the selective Bruton's tyrosine kinase inhibitor zanubrutinib in 385 patients with B-cell malignancies. Here, we present safety and efficacy outcomes for the 53 enrolled patients with relapsed/refractory MZL (n = 20) and relapsed/refractory FL (n = 33), all of whom were enrolled during the part 2 dose expansion, and therefore received zanubrutinib at the recommended phase 2 dose.

Diagnosis and management of malignant sublingual gland tumors: a narrative review.

Objective: In this article we review the literature on the malignant sublingual gland tumors from a surgical perspective.

Background: Sublingual gland tumors occur with a very low incidence and most are malignant tumors. The extent of treatment, clinical outcomes and prognosis of malignant sublingual gland tumors have not been well defined, due to the rarity of this disease.

MiR-30a and miR-200c differentiate cholangiocarcinomas from gastrointestinal cancer liver metastases.

Prior studies have demonstrated the utility of microRNA assays for predicting some cancer tissue origins, but these assays need to be further optimized for predicting the tissue origins of adenocarcinomas of the liver. We performed microRNA profiling on 195 frozen primary tumor samples using 14 types of tumors that were either adenocarcinomas or differentiated from adenocarcinomas. The 1-nearest neighbor method predicted tissue-of-origin in 33 samples of a test set, with an accuracy of 93.

Methods: The two entities organised a combined symposium and post-meeting interactions among representatives of major cancer centres from seventeen Asian countries to outlining major challenges and countermeasures.

Associations of coffee and tea consumption with lung cancer risk.

Associations of coffee and tea consumption with lung cancer risk have been inconsistent, and most lung cancer cases investigated were smokers. Included in this study were over 1.1 million participants from 17 prospective cohorts.

Clinical impact of frailty on treatment outcomes of elderly patients with relapsed and/or refractory multiple myeloma treated with lenalidomide plus dexamethasone.

We compared efficacy and safety, according to frailty, of elderly patients with relapsed and refractory multiple myeloma (RRMM) treated with lenalidomide and dexamethasone (Rd), for whom bortezomib treatment had failed. Patients, 164 (52.9%) and 146 (47.

An Asian Body to Tackle Cancers in Asia - The Asian National Cancer Centers Alliance.

The socioeconomic burden of cancer is growing rapidly in the Asian region, with a concentrated burden on low- and middle- income countries. The residents of this region, representing almost 60% of the global population, demonstrate an eclectic and complex nature, with huge disparities in ethnicity, sociocultural practices among others. The Asian National Cancer Centers Alliance (ANCCA) was established in 2005 by heads of several national cancer centers (NCCs) in the region to address common issues and concerns among Asian countries.

Pomalidomide, cyclophosphamide, and dexamethasone for elderly patients with relapsed and refractory multiple myeloma: A study of the Korean Multiple Myeloma Working Party (KMMWP-164 study).

Patients with transplant-ineligible relapsed and refractory multiple myeloma (RRMM) have a short life expectancy, especially when they have failed both the proteasome inhibitor and immunomodulator therapies. This study aimed to assess the efficacy and safety of pomalidomide, cyclophosphamide, and dexamethasone (PCd) in elderly patients with RRMM. This phase 2 clinical trial recruited 55 elderly patients with RRMM.

The effectiveness and safety of lenalidomide and dexamethasone in patients with relapsed/refractory multiple myeloma in real-world clinical practice: a study of the Korean Multiple Myeloma Working Party (KMMWP-151 study).

Although lenalidomide plus dexamethasone (RD) is a therapeutic option for relapsed/refractory multiple myeloma (RRMM), limited real-world clinical data exist. The purpose of this study was to estimate efficacy and safety of RD in RRMM patients of the clinical practice. Data from patients at 25 university hospitals in South Korea between October 2009 and December 2016 were collected retrospectively.

Clinical features and treatment outcomes of limited-stage mantle cell lymphoma: Consortium for Improving Survival of Lymphoma report.

Limited-stage (Ann Arbor stage I or II) mantle cell lymphoma (MCL) is an extremely rare disease. Thus, there is little data on the clinical features and treatment outcomes of patients with early-stage MCL. We examined consecutive stage I or II MCL 41 cases diagnosed between 2000 and 2016 in 16 institutions of the Consortium for Improving Survival of Lymphoma group.

Smoking, Serology, and Gastric Cancer Risk in Prospective Studies from China, Japan, and Korea.

Smoking is an established risk factor for gastric cancer development. In this study, we aimed to assess prospectively the association of smoking with gastric cancer risk in 1,446 non-cardia gastric cancer cases and 1,796 controls from China, Japan, and Korea with consideration of infection as a potential effect modifier. Applying logistic regression models stratified by study and adjusted for age and sex we found that current, but not former, smoking was significantly associated with gastric cancer risk [OR = 1.

A Phase I/II, Open-Label, Prospective, Multicenter Study to Evaluate the Efficacy and Safety of Lower Doses of Bortezomib Plus Busulfan and Melphalan as a Conditioning Regimen in Patients with Multiple Myeloma Undergoing Autologous Peripheral Blood Stem Cell Transplantation: The KMM103 Study.

A phase I/II trial was conducted to explore the safety and activity of the addition of bortezomib on days -6, -3, and +1 relative to the day of autologous stem cell transplantation (ASCT) to a conditioning regimen with busulfan and melphalan (BuMel; 3.2 mg/kg/day busulfan on days -5 to -3 and 140 mg/m/day melphalan on day -2) in patients with multiple myeloma (MM) following bortezomib-based induction chemotherapy. In phase I, doses of bortezomib (.

Brief report: Clinical experiences after emergency use of daratumumab monotherapy for relapsed or refractory multiple myeloma in real practice.

Despite the recently reported efficacy of daratumumab monotherapy for patients with relapsed or refractory multiple myeloma, outcomes in real practice following daratumumab monotherapy have yet to be investigated. A multi-center retrospective study of 16 Korean patients receiving daratumumab monotherapy for relapsed or refractory multiple myeloma was conducted. The overall response rate was 56.

Validation of a Blood Biomarker for Identification of Individuals at High Risk for Gastric Cancer.

Background: is the leading cause of gastric cancer, yet the majority of infected individuals will not develop neoplasia. Previously, we developed and replicated serologic biomarkers for gastric cancer risk among prospective cohorts in East Asia and now seek to validate the performance of these biomarkers in identifying individuals with premalignant lesions.

Methods: This cross-sectional study included 1,402 individuals from Linqu County screened by upper endoscopy.

CANcer-specific Evaluation System (CANES): a high-accuracy platform, for preclinical single/multi-biomarker discovery.

The recent creation of enormous, cancer-related "Big Data" public depositories represents a powerful means for understanding tumorigenesis. However, a consistently accurate system for clinically evaluating single/multi-biomarkers remains lacking, and it has been asserted that oft-failed clinical advancement of biomarkers occurs within the very early stages of biomarker assessment. To address these challenges, we developed a clinically testable, web-based tool, CANcer-specific single/multi-biomarker Evaluation System (CANES), to evaluate biomarker effectiveness, across 2,134 whole transcriptome datasets, from 94,147 biological samples (from 18 tumor types).

The clinical impact of thalidomide maintenance after autologous stem cell transplantation in patients with newly diagnosed multiple myeloma in real clinical practice of Korea.

In real clinical settings (not clinical trials), thalidomide has been accepted as maintenance therapy to patients with multiple myeloma (MM) because of the cost of drugs, the limitations of medical insurance, etc., in our country (South Korea). The purpose of this study was to evaluate the utility of thalidomide maintenance for improving survival in transplantation-eligible patients with MM in the real clinical field.

Improving gastric cancer preclinical studies using diverse in vitro and in vivo model systems.

Background: "Biomarker-driven targeted therapy," the practice of tailoring patients' treatment to the expression/activity levels of disease-specific genes/proteins, remains challenging. For example, while the anti-ERBB2 monoclonal antibody, trastuzumab, was first developed using well-characterized, diverse in vitro breast cancer models (and is now a standard adjuvant therapy for ERBB2-positive breast cancer patients), trastuzumab approval for ERBB2-positive gastric cancer was largely based on preclinical studies of a single cell line, NCI-N87. Ensuing clinical trials revealed only modest patient efficacy, and many ERBB2-positive gastric cancer (GC) patients failed to respond at all (i.
