Outcome of Multiple Myeloma Patients With Hepatitis B Surface Antigen: Korean Multiple Myeloma Working Party 2103 Study.

BACKGROUND: Hepatitis B virus reactivation (HBVr) is a well-known complication of systemic chemotherapy for particularly hematologic malignancies in HBV carriers. We performed a multicenter retrospective study to investigate the incidence and risk factors of HBVr in patients with hepatitis B surface antigen (HBsAg)-positive multiple myeloma (MM). METHODS: We included 123 patients with HBsAg-positive MM who had received systemic therapy. The primary objective of the study was to evaluate the incidence of HBVr in patients with HBsAg-positive MM. RESULTS: The median age was 59 years, and 72 patients were male. With a median follow-up duration of 41.4 months, there were 43 instances of HBVr in 35 patients (28.5%): 29 treatment-related HBVr occurred during 424 treatments. Treatments containing antiviral prophylaxis were associated with a significantly lower incidence of HBVr compared to those without (14.4% vs. 1.9%, P < 0.001). Moreover, treatment with cyclophosphamide (P = 0.002) and doxorubicin (P = 0.053) were risk factors for HBVr; stem cell transplantation was not associated with HBVr. There was no significant difference in overall survival between patients with and without HBVr (P = 0.753) and myeloma progression was the major cause of death. CONCLUSION: Considering the low incidence of HBVr in patients who had received antiviral prophylaxis, HBsAg-positivity should not impede patients from receiving optimal antimyeloma treatment or participating in clinical trials.

Knowledge, attitudes, and perceptions associated with HPV vaccination among female Korean and Chinese university students.

BACKGROUND: Human papillomavirus (HPV) vaccination is a form of primary prevention for cervical cancer. The HPV vaccination rate of female university students is not high in Korea and China. Therefore, the purpose of this study was to identify and compare the factors associated with intention to receive HPV vaccination between Korean and Chinese female university students. METHODS: The participants were 273 Korean and 317 Chinese female university students who had not been vaccinated for HPV, and data were collected using a self-reported questionnaire about attitudes toward HPV vaccination, HPV knowledge, perceptions of HPV infection, and intention to receive HPV vaccine. RESULTS: There were no significant differences between the Korean and Chinese female university students in HPV knowledge, attitudes, perceptions, and vaccination intention. The factors influencing the intention of HPV vaccination in Korean students were a positive attitude toward the HPV vaccine and a high HPV knowledge score. For Chinese students, sexual experience, awareness of genital warts, a positive attitude toward the HPV vaccine, a high HPV knowledge scores, a perception of the seriousness of HPV infection, and negative emotions regarding HPV infection were significant factors. CONCLUSIONS: It is important to improve attitudes and knowledge about HPV and the HPV vaccine in order to enhance HPV vaccination both in Korea and China. Perceived seriousness and negative emotions regarding HPV infection should be used as a framework to develop subject-tailored interventions in China.

Gender Differences in Sexual Information Needs and Relating Factors in Cancer Patients: A Cross-Sectional Survey.

This study aimed to identify the sexual information requirements and related factors according to gender to improve sexual health in cancer patients. In this cross-sectional study, a total of 687 cancer patients from a single cancer center in Korea completed a self-reported questionnaire. Multiple logistic regression analysis was used to compare the sexual information requirements and related factors among cancer patients. The results showed that male cancer patients had higher demands for sexual information than female cancer patients (t = 27.11, p < 0.001). Men appeared to have a greater need than women in the need for sexual information (t = 30.41, p < 0.001) and professional sexual intervention (t = 21.97, p < 0.001). Regarding sexual information needs, income (OR: 0.43, 95% CI: 0.25 to 0.73) was a significant factor in men. In women, age (OR: 0.51, 95% CI: 0.31 to 0.86), alcohol consumption (OR: 1.88, 95% CI: 1.12-3.16), and chemotherapy (OR: 1.87, 95% CI: 1.12-3.12) were significant factors. Significant differences in the overall sexual information needs and related factors were observed between male and female cancer patients. Therefore, a strategy needs to be established to improve the sexual health of cancer patients considering gender differences.

The Attitudes of Physicians and the General Public toward Prognostic Disclosure of Different Serious Illnesses: a Korean Nationwide Study.

BACKGROUND: Although international guidelines recommend palliative care approaches for many serious illnesses, the palliative needs of patients with serious illnesses other than cancer are often unmet, mainly due to insufficient prognosis-related discussion. We investigated physicians' and the general public's respective attitudes toward prognostic disclosure for several serious illnesses. METHODS: We conducted a cross-sectional survey of 928 physicians, sourced from 12 hospitals and the Korean Medical Association, and 1,005 members of the general public, sourced from all 17 administrative divisions in Korea. RESULTS: For most illnesses, most physicians (adjusted proportions - end-organ failure, 99.0%; incurable genetic or neurologic disease, 98.5%; acquired immune deficiency syndrome [AIDS], 98.4%; stroke or Parkinson's disease, 96.0%; and dementia, 89.6%) and members of the general public (end-organ failure, 92.0%; incurable genetic or neurologic disease, 92.5%; AIDS, 91.5%; stroke or Parkinson's disease, 92.1%; and dementia, 86.9%) wanted to be informed if they had a terminal prognosis. For physicians and the general public, the primary factor to consider when disclosing terminal status was "the patient's right to know his/her condition" (31.0%). Yet, the general public was less likely to prefer prognostic disclosure than physicians. Particularly, when their family members were patients, more than 10% of the general public did not want patients to be informed of their terminal prognosis. For the general public, the main reason for not disclosing prognosis was "psychological burden such as anxiety and depression" (35.8%), while for the physicians it was "disclosure would have no beneficial effect" (42.4%). CONCLUSION: Most Physicians and the general public agreed that disclosure of a terminal prognosis respects patient autonomy for several serious illnesses. The low response rate of physicians might limit the generalizability of the results.

The Impacts of Prognostic Awareness on Mood and Quality of Life Among Patients With Advanced Cancer.

BACKGROUND: Accurate awareness of the prognosis is an important factor in the treatment decision of patients with advanced cancer; however, prognostic disclosure is still subject to debate because it can reduce patient's satisfaction and increase depression. AIM: The purpose of this study is to assess whether patients' prognostic awareness is associated with decreased quality of life (QoL) or increased depressive mood in patients with advanced cancer. DESIGN AND PARTICIPANTS: In this cohort study, 386 patients with advanced cancer were recruited across 3 periods from December 2016 to August 2018. The outcome of this study was a change in QoL and depression according to the patients' prognostic awareness at baseline, 3 months, and 6 months. RESULTS: This study found significant differences in changes of QoL based on patients' prognostic awareness. From baseline to 3 months, emotional functioning (P = .039), pain (P = .042), existential well-being (P = .025), and social support (P = .038) subscale scores improved significantly more in those with lack of prognostic awareness. Over 6 months, the group without prognostic awareness improved significantly in terms of physical functioning (P = .037), emotional functioning (P = .002), nausea/vomiting (P = .048), and constipation (P = .039) subscale scores and existential well-being scores (P = .025). No significant difference between the groups was found in terms of depression. CONCLUSION: Accurate prognostic awareness may pose harm and may provide no additional benefits in terms of QoL and mood among patients with advanced cancer for a short period of time.

Comparison of three risk stratification models for non-clear cell renal cell carcinoma patients treated with temsirolimus as first-line therapy.

BACKGROUND/AIMS: For metastatic renal cell carcinoma (RCC), various prognostic scoring systems have been developed. However, owing to the low prevalence of nonclear cell RCC, the three most commonly used tools were mainly developed based on patients with clear cell histology. Accordingly, this study applied three prognostic models to Korean non-clear cell RCC patients treated with first-line temsirolimus. METHODS: This study analyzed data for 74 patients with non-clear cell RCC who were treated with temsirolimus as the first-line therapy at eight medical centers between 2011 and 2016. The receiver-operating characteristic (ROC) curves for the different prognostic models were analyzed. RESULTS: Twenty-seven (36.5%), 24 (32.4%), and 44 patients (59.5%) were assigned to the poor prognosis groups of the Memorial Sloan-Kettering Cancer Center (MSKCC), International Metastatic RCC Database Consortium (IMDC), and Advanced Renal Cell Carcinoma (ARCC) risk stratification models, respectively. All three prognostic models reliably discriminated the risk groups to predict progression-free survival and overall survival (p < 0.001). The area under the ROC curve (AUC) for progression and survival was highest for the ARCC model (0.777; 0.734), followed by the IMDC (0.756; 0.724) and the MSKCC (0.742; 0.712) models. Furthermore, the sensitivity and specificity for predicting progression were highest with the ARCC model (sensitivity 63.6%, specificity 85.7%), followed by the MSKCC (sensitivity 58.2%, specificity 86.5%) and the IMDC models (sensitivity 56.4%, specificity 85.7%). CONCLUSION: All three prognostic models accurately predicted the survival of the non-clear cell RCC patients treated with temsirolimus as the first-line therapy. Furthermore, the ARCC risk model performed better than the other risk models in predicting survival.

Clinical Characteristics of Clear Cell Ovarian Cancer: A Retrospective Multicenter Experience of 308 Patients in South Korea.

PURPOSE: The purpose of this study was to evaluate clinical characteristics and treatment pattern of ovarian clear cell carcinoma (OCCC) in Korea and the role of adjuvant chemotherapy in early stage. MATERIALS AND METHODS: Medical records of 308 cases of from 21 institutions were reviewed and data including age, performance status, endometriosis, thromboembolism, stage, cancer antigen 125, treatment, recurrence, and death were collected. RESULTS: Regarding stage of OCCC, it was stage I in 194 (63.6%), stage II in 34 (11.1%), stage III in 66 (21.6%), and stage IV in 11 (3.6%) patients. All patients underwent surgery. Optimal surgery (residual disease ≤ 1 cm) was achieved in 89.3%. Majority of patients (80.5%) received postoperative chemotherapy. The most common regimen was taxane-platinum combination (96%). Median relapse-free survival (RFS) was 138.5 months for stage I, 33.4 for stage II, 19.3 for stage III, and 9.7 for stage IV. Median overall survival (OS) were not reached, 112.4, 48.7, and 18.3 months for stage I, II, III, and IV, respectively. Early-stage (stage I), endometriosis, and optimal debulking were identified as favorable prognostic factors for RFS. Early-stage and optimal debulking were also favorable prognostic factors for OS. Majority of patients with early-stage received adjuvant chemotherapy. However, additional survival benefit was not found in terms of recurrence. CONCLUSION: Majority of patients had early-stage and received postoperative chemotherapy regardless of stage. Early-stage and optimal debulking were identified as favorable prognostic factors. In stage IA or IB, adding adjuvant chemotherapy did not show difference in survival. Further study focusing on OCCC is required.

Correction to: Priorities of a "good death" according to cancer patients, their family caregivers, physicians, and the general population: a nationwide survey.

While recently extending that research, however, we discovered that 236 members of the general population were mistakenly duplicated by the investigating agency (Word Research) and 1241 were reported rather than 1005. Here, we present corrections and discuss the relevant data.

Comparison and correlation among in vitro and in vivo assays to assess cord blood quality according to delivery temperature and time after collection.

Cord blood (CB) has been used as an alternative source for unrelated allogeneic hematopoietic stem cell transplantation. To determine which assay was useful for predicting the successful outcome of CB transplantation, CBs were grouped according to the temperature (4 °C, 24 °C, and 37 °C) and time (24, 48, and 72 h) after collection. The viability, early apoptosis, and colony forming units (CFUs) were ascertained for the total nucleated cells (TNCs) and CD34+ cells; in addition, the engraftment of infused CD34+ cells in NSG mice was determined. The viability of the TNCs and CD34+ cells and total CFUs were significantly decreased whereas the early apoptosis was significantly increased in the 72 h group at 37 °C compared to that of the 24 h group at 24 °C. The viability and early apoptosis of the TNCs correlated with those of CD34+ cells. In addition, the viability and early apoptosis correlated with the number of granulocyte/monocyte progenitor CFUs. In transplanted NSG mice, the frequency of human CD45+ cells decreased in the 72 h group at 24 °C compared to that of the 24 h group at 24 °C and was negatively correlated with early apoptosis of TNCs and CD34+ cells. This study demonstrated that the early apoptosis of TNCs and CD34+ cells constitutes a useful marker for predicting the engraftment of HSCs and may provide helpful data for standard assessment regarding CB quality by analyzing the correlation between in vitro and in vivo assays using NSG mice.

Attitudes of the General Public, Cancer Patients, Family Caregivers, and Physicians Toward Advance Care Planning: A Nationwide Survey Before the Enforcement of the Life-Sustaining Treatment Decision-Making Act.

CONTEXT: To respect a patient's wish for end-of-life care, "the Act on Decisions on Life-Sustaining Treatment for Patients at the End-of-Life" was enacted in South Korea in 2016. Current understanding of people who would be involved in advance care planning (ACP) is crucial to disseminate it systematically. OBJECTIVES: The objective of this study was to investigate awareness and attitudes toward ACP in South Korea. METHODS: A multicenter, nationwide cross-sectional study was conducted, a survey regarding ACP among four groups that would have different positions and experiences: 1001 cancer patients, 1006 family caregivers, 928 physicians, and 1241 members of the general public. RESULTS: A total of 15% of the general population, 33% of the patients and caregivers, and 61% of the physicians had knowledge of advance directives. More than 64% of the general population, above 72% of the patients and caregivers, and 97% of the physicians were willing to do so when the disease status was aggravated or terminal. The possibility for changing the plan, uncertainty as to whether directives would actually be followed, and psychological discomfort were common reasons for not wanting to engage in ACP. Routine recommendations for a specific medical condition, heightened accessibility, and health insurance support were common factors that could help facilitate ACP. CONCLUSION: Our findings suggest that strategies for promoting ACP should reflect different perspectives among the general public, patients, family caregivers, and physicians. Public advocacy, resources for approaching and integrating ACP into routine health care, as well as systematic support provisions are needed.

Quality of Life in Patients With Non-Small Cell Lung Cancer: Structural Equation Modeling.

BACKGROUND: Quality of life (QOL) is important for cancer patients, even for survival. However, factors affecting QOL of non-small cell lung cancer (NSCLC) patients have not been studied sufficiently. OBJECTIVE: The aims of this study were to understand the relationships among social support, resilience, distress, and symptom and to identify predictors of QOL for NSCLC patients. METHODS: Participants were 212 adult patients who visited an outpatient department at a tertiary hospital located in Seoul, Korea. Data were collected using self-reported questionnaires and clinical records. RESULTS: Social support, resilience, distress, symptom burden, and QOL explained 99.9% of the variance in QOL. Social support was not a significant predictor of distress and QOL, but a significant predictor of resilience. Resilience was a significant predictor of both distress and QOL. Distress was not a significant predictor of QOL, but a significant predictor of symptom burden. Symptom burden was a significant predictor of QOL and had the largest direct effect on QOL. Resilience also had an important impact on QOL because resilience influenced QOL in various paths. CONCLUSION: This study suggests that social support, resilience, distress, and symptom burden are predictors of QOL in an NSCLC population. These predictors had direct and indirect effects on each other and on QOL. IMPLICATIONS FOR PRACTICE: Developing an interventional program to increase resilience and social support as well as to decrease symptom burden and distress may be necessary to improve QOL of NSCLC patients.

Comparison of attitudes towards five end-of-life care interventions (active pain control, withdrawal of futile life-sustaining treatment, passive euthanasia, active euthanasia and physician-assisted suicide): a multicentred cross-sectional survey of Korean patients with cancer, their family caregivers, physicians and the general Korean population.

OBJECTIVES: This study determined attitudes of four groups-Korean patients with cancer, their family caregivers, physicians and the general Korean population-towards five critical end-of-life (EOL) interventions-active pain control, withdrawal of futile life-sustaining treatment (LST), passive euthanasia, active euthanasia and physician-assisted suicide. DESIGN AND SETTING: We enrolled 1001 patients with cancer and 1006 caregivers from 12 large hospitals in Korea, 1241 members of the general population and 928 physicians from each of the 12 hospitals and the Korean Medical Association. We analysed the associations of demographic factors, attitudes towards death and the important components of a 'good death' with critical interventions at EoL care. RESULTS: All participant groups strongly favoured active pain control and withdrawal of futile LST but differed in attitudes towards the other four EoL interventions. Physicians (98.9%) favoured passive euthanasia more than the other three groups. Lower proportions of the four groups favoured active euthanasia or PAS. Multiple logistic regression showed that education (adjusted OR (aOR) 1.77, 95% CI 1.33 to 2.36), caregiver role (aOR 1.67, 95% CI 1.34 to 2.08) and considering death as the ending of life (aOR 1.66, 95% CI 1.05 to 1.61) were associated with preference for active pain control. Attitudes towards death, including belief in being remembered (aOR 2.03, 95% CI 1.48 to 2.79) and feeling 'life was meaningful' (aOR 2.56, 95% CI 1.58 to 4.15) were both strong correlates of withdrawal of LST with the level of monthly income (aOR 2.56, 95% CI 1.58 to 4.15). Believing 'freedom from pain' negatively predicted preference for passive euthanasia (aOR 0.69, 95% CI 0.55 to 0.85). In addition, 'not being a burden to the family' was positively related to preferences for active euthanasia (aOR 1.62, 95% CI 1.39 to 1.90) and PAS (aOR 1.61, 95% CI 1.37 to 1.89). CONCLUSION: Groups differed in their attitudes towards the five EoL interventions, and those attitudes were significantly associated with various attitudes towards death.

Priorities of a "good death" according to cancer patients, their family caregivers, physicians, and the general population: a nationwide survey.

PURPOSE: Understanding the concept of a "good death" is crucial to end-of-life care, but our current understanding of what constitutes a good death is insufficient. Here, we investigated the components of a good death that are important to the general population, cancer patients, their families, and physicians. METHODS: We conducted a stratified nationwide cross-sectional survey of cancer patients and their families from 12 hospitals, physicians from 12 hospitals and the Korean Medical Association, and the general population, investigating their attitudes toward 10 good-death components. FINDINGS: Three components-"not be a burden to the family," "presence of family," and "resolve unfinished business"-were considered the most important components by more than 2/3 of each of the three groups, and an additional three components-"freedom from pain," "feel that life was meaningful," and "at peace with God"-were considered important by all but the physicians group. Physicians considered "feel life was meaningful," "presence of family," and "not be a burden to family" as the core components of a good death, with "freedom from pain" as an additional component. "Treatment choices' followed, "finances in order," "mentally aware," and "die at home" were found to be the least important components among all four groups. CONCLUSION: While families strongly agreed that "presence of family" and "not be a burden to family" were important to a good death, the importance of other factors differed between the groups. Health care providers should attempt to discern each patient's view of a good death.

Attitudes toward early palliative care in cancer patients and caregivers: a Korean nationwide survey.

Integrated early palliative care (EPC) improves quality of life and reduces psychological distress in adult patients with cancer and caregivers, but attitudes toward EPC have been poorly studied. We aimed to investigate attitudes toward EPC in a nationwide survey of patients with cancer and caregivers. From July to October 2016, we administered nationwide questionnaires examining attitudes toward EPC in patients with cancer (n = 1001) and their families (n = 1006) from 12 Korean hospitals. When an individual considered EPC unnecessary, the reasons were collected and analyzed. Factors associated with perception of EPC were examined. A majority of patients (84.5%) and caregivers (89.5%) had positive attitudes toward EPC. The most common reasons for deeming EPC unnecessary were that EPC may be an obstacle to cancer treatment (patients: 37%; caregivers: 23%; respectively) or that they were not sure if EPC is beneficial (patients: 21%; caregivers: 24%; respectively). Financial burden as a reason was more evident in caregivers (23%) than in patients (17%). Male gender, age <50, early stage, intensive care unit admission, and not believing that dying people should prepare to practice charity were associated with patients' negative attitudes. In caregivers, opposition to EPC was associated with not thinking death should be feared, not thinking people should be remembered, and lower educational level. Our findings showed that significant numbers of patients with advanced cancer and family caregivers showed positive attitudes toward EPC. However, more than 10% of participants did not consider EPC necessary. Physicians' communication with patients and caregivers and financial support could help overcome the barriers of EPC.

The impact of caregiver's role preference on decisional conflicts and psychiatric distresses in decision making to help caregiver's disclosure of terminal disease status.

PURPOSE: The objective of this study was to investigate the impact of caregivers' role preference in decision making on conflicts and psychiatric distresses. METHODS: The responses of 406 caregivers of terminal cancer patients enrolled in a trial determining the efficacy of a decision aid focused on the disclosure of terminal disease status were included in this secondary analysis. The outcomes include the change scores of the Decision Conflict Scale (DCS) and depression and anxiety subscales of the Hospital Anxiety and Depression Scale (HADS) at the 1 and 3 months from baseline. The linear mixed model was employed to discover the impact of caregivers' decisional role preference on the outcomes. FINDINGS: Of the 406, 137 (33.7%) showed an active role preference and 269 (66.3%) showed a passive role preference. In the post hoc analysis of the adjusted differences of change scores between passive caregivers who received decision aid (passive-decision aid) and active caregivers with decision aid (active-decision aid), non-significant differences were observed in the DCS. However, at the 3-month, the change scores of the HADS depression subscale increased by 4.43 (effect size, 0.71) and those of the HADS anxiety subscale increased by 4.14 (effect size, 0.61) in the passive-decision aid group than in active-decision aid group, showing moderate to large difference. CONCLUSIONS: These findings suggest that information might be ethically recommended in a format that is interactive and tailored to how much an individual wishes to be involved in the decision-making process.

Multicenter, cross-sectional observational study of the impact of neuropathic pain on quality of life in cancer patients.

PURPOSE: Neuropathic cancer pain (NCP) is a common and potentially debilitating symptom in cancer patients. We investigated the prevalence of NCP, as well as its management and association with QOL. METHODS: Cancer patients with pain ≥1 on the visual analogue scale (VAS) were surveyed with the Douleur Neuropathique (DN4) questionnaire, the Brief Pain Inventory-Short Form (BPI-SF), and the EuroQOL five dimensions (EQ-5D) questionnaire. The associations between NCP and pain severity or NCP and QOL, while controlling for variables relevant to QOL, were then analyzed. RESULTS: A total of 2003 patients were enrolled in this survey; the prevalence of NCP was 36.0% (n = 722, 95% CI, 32.5-39.5). We found that NCP in cancer patients was closely correlated to a higher pain severity (BPI-SF; 4.96 ± 1.94 versus 4.24 ± 2.02, p < 0.001), and in patients with NCP, pain more severely interfered with daily living, as compared to those without NCP (BPI-SF; 4.86 ± 2.71 versus 4.41 ± 2.87, p < 0.001). Patients with NCP also had worse QOL than those without NCP, as measured by EQ-5D index score (0.47 ± 0.30 vs. 0.51 ± 0.30, p = 0.005), and this was confirmed using multivariate analysis (p < 0.001), even after controlling for other variables such as age, sex, disease stage, cancer duration, radiotherapy, chemotherapy, and comorbidities. Importantly, adjuvant analgesics were used in less than half of patients with NCP (n = 358, 46.4%). CONCLUSIONS: We found that NCP in cancer patients was significantly associated with a worsened QOL, and current management is inadequate. Therefore, future research aimed at developing improved strategies for management of NCP is required.

Clinical significance of systemic chemotherapy after curative resection of metachronous pulmonary metastases from colorectal cancer.

PURPOSE: The use of systemic chemotherapy after resection remains controversial in patients with resectable metachronous pulmonary metastases from colorectal cancer (CRC). This retrospective study compared systemic chemotherapy with observation alone after resection of pulmonary metastases from CRC. METHODS: Between 2001 and 2015, 91 patients with metachronous pulmonary metastases underwent curative surgical resection at five centers. Patients with stage IV at diagnosis were excluded. Overall survival (OS) was defined as the time from pulmonary resection until death. The disease-free interval (DFI) was defined as the time from pulmonary resection until recurrence or death. RESULTS: Among the 91 patients, 63 were in the chemotherapy group, while 28 were in the observation alone group. The characteristics were similar between the two groups, except for the carcinoembryonic antigen level after pulmonary metastases and the use of adjuvant treatment after resection of the primary tumor. With a median follow-up duration of 46 months (11-126), the estimated 5-year DFI and OS rates were 32.8 and 61.4%, respectively. The chemotherapy following pulmonary resection was not significantly associated with the DFI (p = 0.416) and OS (p = 0.119). CONCLUSION: Systemic chemotherapy after pulmonary resection was not found to have a significant effect on survival.

Biweekly dose-dense gemcitabine-oxaliplatin and dexamethasone for relapsed/refractory aggressive non-Hodgkin lymphoma: A multicenter, single-arm, phase II trial.

AIM: We performed a phase II study to evaluate the efficacy of combination chemotherapy consisting of gemcitabine, dexamethasone and oxaliplatin (GemDOx) as a biweekly regimen and salvage therapy in patients with relapsed or refractory aggressive non-Hodgkin lymphoma (NHL). METHODS: Gemcitabine (1000 mg/m(2) ) and oxaliplatin (85 mg/m(2) ) were administered intravenously on days 1 and 15, and dexamethasone (40 mg) was administered orally on days 1-4. RESULTS: Twenty-nine patients were enrolled, and most patients had diffuse large B-cell lymphoma (n = 18). The median age of the patients and median prior number of chemotherapy cycles were 53 (range, 26-74) years and 1 (range, 1-4) cycle, respectively. Only 17 (58.6%) and 9 (31.0%) patients completed two or more and four or more cycles, respectively, and the median number of received cycles was two (range, 1-8). Overall response rates were 27.6% (complete response in 13.8%) among intent-to-treat patients and 47.1% (complete response in 23.5%) among patients who had received at least two GemDOx cycles. Median progression-free survival and median overall survival were 3.9 and 20.5 months, respectively. The most-frequent grade 3 or 4 toxicity was neutropenia (22.9%), and no grade 3 or 4 peripheral neurotoxicity was noted. CONCLUSION: GemDOx chemotherapy, therefore, showed modest activity against relapsed or refractory aggressive NHL, although toxicities were acceptable.

Current status of cord blood banking during first two years of 'National Government-Assigned Public Cord Blood Banks Operation' in Korea.

Cord blood (CB) has become a viable stem cell source for hematopoietic stem cell transplantation (HSCT), and public cord blood banks (CBBs) have been established to manage donated cord blood units (CBUs) for unrelated HSCT. As the potential uses for CB continue to grow, there is a global tendency to encourage public CBBs. The aim of this study was to investigate the current status of public CBBs that were designated and supported by the Korean national government. We analyzed 6,168 CBUs preserved at the 3 Government-Assigned Public CBBs during their first two years of operation (2012-2013) and the standard operating procedures for CB processing at each CBB. CBU inventories at ALLCORD, Catholic HSC Bank and Fatima Public CBB were 4,022, 1,207 and 939 units, respectively. Total nucleated cell (TNC) counts per unit were 11.0 × 10(8) at ALLCORD, 10.7 × 10(8) at Fatima and 9.8 × 10(8) at Catholic, and all far exceeded the requirement for cryopreservation under the law (7.0 × 10(8)). CD34(+) cell counts and % were as follows: 3.5 × 10(6) (0.31 %) in ALLCORD, 2.2 × 10(6) (0.20 %) in Fatima and 2.2 × 10(6) (0.22 %) in Catholic. All the three banks observed the 'CB Act' in dealing with CBUs, including collection, processing, laboratory tests and cryopreservation. Government supported and strictly law-abiding public CBBs in Korea have considerable CBU inventories of high quality in terms of efficacy and safety. Legislation and accompanying government-support will be helpful for establishing CB standardization, vitalizing CBT and improving clinical outcomes.

The Understanding of Terminal Cancer and Its Relationship with Attitudes toward End-of-Life Care Issues.

BACKGROUND: Although terminal cancer is a widely used term, its meaning varies, which may lead to different attitudes toward end-of-life issues. The study was conducted to investigate differences in the understanding of terminal cancer and determine the relationship between this understanding and attitudes toward end-of-life issues. METHODS: A questionnaire survey was performed between 2008 and 2009. A total of 1242 cancer patients, 1289 family caregivers, 303 oncologists from 17 hospitals, and 1006 participants from the general population responded. RESULTS: A "6-month life expectancy" was the most common understanding of terminal cancer (45.6%), followed by "treatment refractoriness" (21.1%), "metastatic/recurrent disease" (19.4%), "survival of a few days/weeks" (11.4%), and "locally advanced disease" (2.5%). The combined proportion of "treatment refractoriness" and "6-month life expectancy" differed significantly between oncologists and the other groups combined (76.0% v. 65.9%, P = 0.0003). Multivariate analyses showed that patients and caregivers who understood terminal cancer as "survival of a few days/weeks" showed more negative attitudes toward disclosure of terminal status compared with participants who chose "treatment refractoriness" (adjusted odds ratio [aOR] 0.42, 95% confidence interval [CI] 0.22-0.79 for patients; aOR 0.34, 95% CI 0.18-0.63 for caregivers). Caregivers who understood terminal cancer as "locally advanced" or "metastatic/recurrent disease" showed a significantly lower percentage of agreement with withdrawal of futile life-sustaining treatment compared with those who chose "treatment refractoriness" (aOR 0.19, 95% CI 0.07-0.54 for locally advanced; aOR 0.39, 95% CI 0.21-0.72 for metastatic/recurrent). CONCLUSIONS: The understanding of terminal cancer varied among the 4 participant groups. It was associated with different preferences regarding end-of-life issues. Standardization of these terms is needed to better understand end-of-life care.
