The current issue of the Korean Journal of Hematology includes a very impressive, surprising report describing, for the first time, the statistics of hematologic malignancies in Korea [1]. In fact, until now, no reliable nationwide cancer statistics describing hematologic malignancies have been published in Korea. While the report presented in this current issue may be somewhat incomplete, it represents an excellent database that can be used both domestically and worldwide as an important source of cancer statistics from Korea. Because the database contains all aspects of population-based, disease-specific statistics, along with survival- and death-related data from 1993 to 2008, we can analyze and compare our own data with that of other countries, allowing high-ranked public officials to shape national policies and health strategies in the field of hematologic malignancy in the future. \u0000 \u0000On the other hand, this statistics presented in the current issue could be representative of the estimated incidence and prevalence since we still do not have a reporting system that enables accurate data collection and creation of a nationwide database for specific regions or specific periods of time. The data from 1993 and prior should differ quite dramatically from data for 2008. However, we recognize that the publication of this statistical report provides us with a beginning from which we can establish a reliable health reporting system in Korea. Undoubtedly, this is the first step toward developing more complementary and up-to-date health statistics in this country. \u0000 \u0000Based on an annually increasing trend, we can say for certain that greater than 8,000 new cases of blood cancer patients were diagnosed in 2008 according to data from the Korea National Cancer Incidence Database (KNCIDB) [1, 2]. In addition, survival and mortality data from 1993 to 2008 were obtained from the Korea National Statistics Office (KNSO) [1, 2]. These data were combined, and the current report calculated, for the first time in Korea, the incidence, mortality, prevalence, limited-duration prevalence, and changes in the annual age-standardized cancer incidence rates. Now, Korean medical students can be taught oncology using Korea's own statistics, rather than the statistics of other countries. Therefore, although it is somewhat shameful to admit that this is the first publication of national data on hematologic malignancies, we should consider this a memorable and historical achievement. \u0000 \u0000To establish further reliable statistics on hematologic malignancies, we anticipate that more aggressive efforts will be made to collect data from every regional database in Korea. Based on a recent report published in the Journal Cancer Research and Treatment in 2011 [2], we found that 2,561 new cases of leukemia were diagnosed in Korea in 2008. In contrast to this report, the most recent report published in our journal showed that 2,262 new cases of lymphoid and myeloid leukemia occurred","PeriodicalId":23001,"journal":{"name":"The Korean Journal of Hematology","volume":"47 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5045/kjh.2012.47.1.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30554571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even so, relapse occurs in a substantial number of patients with an apparently complete clinical response. It is therefore possible that a subset of lymphoma cells that remain viable during treatment causes the relapse. The cancer stem cell hypothesis postulates the presence of this specific cell population in cancers. It suggests that cancers are derived from cancer stem cells, which are a particular subset of cancer cells with stem-like properties, including self-renewal [1]. Since the existence of cancer stem cells was demonstrated in acute myeloid leukemia [2], various surface markers have been identified to isolate cancer stem cells from such solid cancers as breast, brain, and colon. Although a recent publication suggested the probability of lymphoma stem cells in non-Hodgkin lymphoma [3], it did not offer sufficient data to support the presence of cancer stem cells as an origin of lymphoma. However, given the potential role of cancer stem cells in the pathogenesis of cancers, the possibility of lymphoma stem cells deserves attention, for it could improve our understanding of lymphoma biology and lead to the development of a new therapeutic target for lymphomas.","PeriodicalId":23001,"journal":{"name":"The Korean Journal of Hematology","volume":"46 4","pages":"211-3"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5045/kjh.2011.46.4.211","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30398083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
