Because ET/PV manifests with diverse symptoms, including non-specific symptoms and symptoms pertaining to other organ systems. Based on the findings, we consider that it is essential to disseminate information about the WHO diagnostic criteria/clinical symptoms and possibility of latent ET/PV to all departments of the hospital, and to establish cooperation between the department of hematology and other departments.

Risk factors for immune-related adverse events(irAEs)associated with immune checkpoint inhibitors(ICIs) remain to be obscure. Therefore, we evaluated the patient background and clinical findings to identify risk factors for the development of irAEs.

The subjects consisted of 86 patients treated with ICIs between August 2018 and March 2020. read more They were classified into 2 groups who developed irAEs(irAE group)and did not develop irAEs(non-irAE group).

The median age of the subjects was 70 years(39-84 years), and there were 65 males. The underlying disease was non-small cell lung cancer in 51 patients, gastric cancer in 14, renal cell cancer in 9, urothelial cancer in 11, and MSI-high small bowel cancer in 1. The irAE group, in whom treatment with ICIs was discontinued, included 16 patients(18.6%), and the non-irAE group included 70 patients(81.4%). The median number of treatment cycles was 8(1-91), and the median treatment period was 4 months(1-45 months). Evaluation in our hospital revealed no significant background factors, such as gender, age, or the treatment period, as risk factors for the development of eras. Lung disorders were frequently observed after the third-line treatment and in patients with non-small cell lung cancer.

At present, the prediction of the development of irAEs is difficult. Careful follow-up observation and early irAEs management are important. In addition, further studies are necessary to identify risk factors for the development of irAEs.

Here, we identified microRNAs(miRNAs) expressed after treatment with olaparib, which differed in the presence or absence of BRCA1 mutations in triple negative breast cancer(TNBC), and examined the changes in miRNAs after exposure to the combination of the PARP-1 inhibitor and a chemotherapeutic agent. After exposure to the PARP-1 inhibitor, the expression of miR-141, miR-155, miR-205, and miR-223 decreased in MDA-MB-231, HCC1143, and BT549 cells and increased more than 10 times in MDA-MB-436 cells. Moreover, the expression of miR-141 in MDA-MB-436 cells treated with the PARP-1 inhibitor together with gemcitabine increased more than 10 times; additionally, the expression of miR-205 increased more in the context of combination therapy versus single exposure to olaparib. The miR-200 family(including miR-141)and miR- 205 are known to function as ZEB1/2 targets and to act as epithelial-to-mesenchymal transition(EMT)-suppressors. Overall, these results suggest that it may be possible to recover the sensitivity of TNBC cells to chemotherapy via the suppressing EMT through the use of a PARP-1 inhibitor in the context of BRCA1 mutation.Genome information has been utilized for the determination of cancer therapy, where some of the hereditary cancer chance to be diagnosed by the analysis of germline variants. The more genomic technology has advanced, the more interpretation of genomic information has been complicated. It is required to enhance the medical network to provide strong support and to determine the appropriate medicine for patients. In this paper, we will discuss the essential roles of genomic counselors in the age of genomic medicine."Counseling on Cancer Genomic Medicine" was added to the list of roles of cancer consultation centers located in Designated Cancer Hospitals under on the Third Cancer Control Act established in 2018. Although cancer consultation centers do not make decisions on whether to conduct genetic testing, it has been revealed that a certain number of such consultations are taking place. Consultations on genetic panel testing are expected to further increase in the future. In order to accommodate this need, individual cancer consultation staff needs to provide services based on the principles of consultation and support. For example, they must have adequate knowledge on the characteristics and limitations of genetic panel testing, understand the true needs of patients and their families, enable such individuals to understand the relevant information, and collaborate with patients and their families to consider the course forward. Furthermore, in order to ensure the quality of individual support, physicians and genetic counselors are expected to contribute by participating in organization-building between genetic counselors, genomic medicine coordinators, and other experts in and outside of hospitals. It is also anticipated that networks will be formed with nearby external institutions and organization, such as Designated Core Hospitals for Cancer Genomic Medicine, Designated Core Hospitals, and Medical Cooperation Hospitals.Based on the results of comprehensive cancer genomic profiling(CGP), only about 10% of cancer patients can be candidates for anticancer drugs that match genetic abnormalities. In the current situation in Japan, clinical trial(BELIEVE trial)is on-going to provide patients with medical treatment opportunities based on the results of CGP test. In this study, patients can try an off-label drug under the Patient-Proposed Healthcare Services who are not eligible for clinical trials such as trials for drug approval, or Advanced Medical Treatment B. More than 40 patients have already participated in the BELIEVE trial. In this section, I will discuss the current status of the BELIEVE trial, challenges in multidisciplinary collaboration, and future prospects.In June 2019, 2 comprehensive cancer genome profiling(CGP)tests were approved with reimbursement, and are now available at designated hospitals stratified to 3 layers on the basis of their roles. The reimbursement-approved CGP tests were restricted to patients with solid tumors that have progressed on standard chemotherapy, rare tumors, or tumors of unknown primary, and perform primary structure analysis of cancer genome on several hundred genes at a time using next generation sequencer. In tumor molecular board, appropriate treatments were recommended based on the interpretation made for results of CGP. Because 2 CGP tests differ functionally in terms of the sample requirements, the target gene sets, and items to be reported, results need to be evaluated carefully. Although the detection rate of genomic alterations in CGP tests is high, the number of cases lead to treatments consistent with genomic alterations is limited. Improving this ratio will be the key for Japanese precision oncology to meet the full potential of the CGP tests.Recent progress in cancer therapy has decreased all-cancer mortality, but cardiovascular adverse events owing to chemotherapy and radiotherapy have greater impact on clinical outcome and quality of life in cancer patients and survivors. There are a wide variety of cardiovascular adverse events related to cancer therapy, and the opportunities requiring specialized care by cardiovascular experts are increasing in clinical practice. Under such circumstances, onco-cardiology is becoming very important as a new discipline and attracting much attention in Japan. The Japanese Onco-Cardiology Society was established in 2017, and continues integration of academic activities to solve challenging problems in this field. Interdisciplinary collaborations between cardiologists and oncologists will be further progressed in medical care, clinical and basic research, and education.Helicobacter pylori infection is one of the most common infectious diseases worldwide. Although the prevalence of H. pylori is gradually decreasing, approximately half of the world's population still becomes infected with this disease. H. pylori is responsible for substantial gastrointestinal morbidity worldwide, with a high disease burden. It is the most common cause of gastric and duodenal ulcers and gastric cancer. Since the revision of the H. pylori clinical practice guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin-based triple therapy for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance, especially from clarithromycin. The clinical practice guidelines for the treatment of H. pylori were updated according to evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after an expert consensus on three recommendations regarding the indication for treatment and eight recommendations for the treatment itself. These guidelines were designed to provide clinical evidence for the treatment (including primary care treatment) of H. pylori infection to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards and will be revised if more evidence emerges in the future.Among parent cyclodextrins (CDs), alpha-CD (a-CD) has been utilized in a number of nutraceutical products, and approved as a dietary fiber to affect glycemic response and reduce dietary fat absorption. To extend our current knowledge on the biology of this natural carbohydrate, here we investigated its potential effects on cellular water uptake and aging. Two independent in vivo biological test systems were used, a single cell Xenopus oocyte with expressed human aquaporin for cell hydration studies and the nematode Caenorhabditis elegans for testing life span in the treated animals. a-CD was found to enhance water uptake through aquaporins of oocytes. Furthermore, the compound promoted longevity in C. elegans. Together, these results raise a rational for assaying a-CD as a potent drug candidate in treating various age-related diseases.Fetal perturbations in DNA methylation during lung development may reveal insights into the enduring impacts on adult lung health and disease during aging that have not been explored altogether before. We studied the association between genome-wide DNA-methylation and post-conception age in fetal-lung (n=78, 42 exposed to in-utero-smoke (IUS)) tissue and chronological age in adult-lung tissue (n=160, 114 with Chronic Obstructive Pulmonary Disease) using multi-variate linear regression models with covariate adjustment and tested for effect modification by phenotypes. Overlapping age-associations were evaluated for functional and tissue-specific enrichment using the Genotype-Tissue-Expression (GTEx) project. We identified 244 age-associated differentially methylated positions and 878 regions overlapping between fetal and adult-lung tissues. Hyper-methylated CpGs (96%) were enriched in transcription factor activity (FDR adjusted P=2x10-33) and implicated in developmental processes including embryonic organ morphogenesis, neurogenesis and growth delay.
