Résumé
Purpose@#Implementation of screening program may lead to increased health disparity within the population if participation differs by socioeconomic status. In Korea, colorectal cancer screening is provided at no or minimal cost to all people over 50 by National Cancer Screening Program. We investigated colorectal cancer screening participation rate and its trend over the last 10 years in relation to disabilities. @*Materials and Methods@#We linked national disability registration data with National Cancer Screening Program data. Age, sex-standardized participation rates were analyzed by type and severity of disability for each year, and factors associated with colorectal cancer screening participation were examined by multivariate logistic regression. @*Results@#Age, sex-standardized participation rate in people without disability increased from 16.2 to 33.9% (change, +17.7), but it increased from 12.7% to 27.2% (change, +14.5) among people with severe disability. People with severe disabilities showed a markedly lower colorectal cancer screening participation rate than people without disability (adjusted odds ratio [aOR], 0.714; 95% confidence interval, 0.713 to 0.720). People with autism (aOR, 0.468), renal failure (aOR, 0.498), brain injury (aOR, 0.581), ostomy (aOR, 0.602), and intellectual disability (aOR, 0.610) showed the lowest participation rates. @*Conclusion@#Despite the availability of a National Cancer Screening Program and overall increase of its usage in the Korean population, a significant disparity was found in colorectal cancer screening participation, especially in people with severe disabilities and or several specific types of disabilities. Greater effort is needed to identify the barriers faced by these particularly vulnerable groups and develop targeted interventions to reduce inequality.

Purpose@#This study aimed to determine whether the diagnosis, treatment approach, and prognosis of multiple myeloma (MM) vary according to the presence and type of disability. @*Materials and Methods@#Demographic, socioeconomic, and medical data were obtained from the National Disability Database, the Korean Central Cancer Registry, and the Korean National Health Insurance claims database. An age- and sex-matched cohort was established using a 1:3 ratio constituted with 2,776,450 people with disabilities and 8,329,350 people without disabilities. Adult patients diagnosed with MM were subsequently selected from this cohort. Disabilities were categorized as physical, communication, intellectual or psychological, and affecting the major internal organs. @*Results@#The cohort included 4,090 patients with MM, with a significantly lower rate per 100,000 persons among people with disabilities than among people without disabilities (29.1 vs. 39.4, p < 0.001). People with disabilities were more likely to undergo dialysis treatment at the time of diagnosis (16.3% vs. 10.0%, p < 0.001), but were less likely to undergo autologous stem cell transplantation (37.5% vs. 43.7%, p=0.072). This trend was more evident among patients with intellectual or psychological disabilities. The median overall survival among patients with disabilities was significantly shorter than that among patients without disabilities (36.8 months vs. 51.2 months, p < 0.001). @*Conclusion@#In Korea, people with disabilities generally have a lower rate of MM diagnosis, receive less intensive treatment, and have a lower survival rate than people without disabilities.
Résumé
PURPOSE: Health-related quality of life (HRQOL) information related to radical prostatectomy (RP) is valuable for prostate cancer (PC) patients needing to make treatment decisions. We aimed to investigate HRQOL change in PC patients who underwent three types of RP (open, laparoscopic, or robotic) and compared their HRQOL with that of general population. MATERIALS AND METHODS: Patients were prospectively recruited between October 2014 and December 2015. European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire (EORTC QLQ-C30) and PC-specific module (PR25) were administered before surgery (baseline) and at postoperative 3 and 12 months. At each time point, HRQOL was compared, and a difference of 10 out of 0-100 scale was considered clinically significant. RESULTS: Among 258 screened patients, 209 (41 open, 63 laparoscopic, and 105 robotic surgeries) were included. Compared to baseline, physical, emotional, and cognitive functioning improved at 12 months. Role functioning worsened at 3 months, but recovered to baseline at 12 months. Pain, insomnia, diarrhea, and financial difficulties also significantly improved at 12 months. Most PR25 scales excluding bowel symptoms deteriorated at 3 months. Urinary symptoms and incontinence aid recovered at 12 months, whereas sexual activity and sexual function remained poor at 12 months. Clinically meaningful differences in HRQOL were not observed according to RP modalities. Compared to the general population, physical and role functioning were significantly lower at 3 months, but recovered by 12 months. Social functioning did not recover. CONCLUSION: Most HRQOL domains showed recovery within 12 months after RP, excluding sexual functioning and social functioning. Our findings may guide patients considering surgical treatment for PC.

PURPOSE: When it comes to cancer care, the psychological well-being of family caregivers has gotten its deserved attention. However, the specific roles that the family caregivers take have not been examined as much. The current study aimed to investigate the distribution of family caregivers' roles, particularly in a family-oriented culture, Korea. MATERIALS AND METHODS: A sample of 439 participants was recruited from 11 national and regional cancer centers in Korea. The participants who were 60 years old or above went through treatments for their gastric, colorectal, or lung cancer. The individual survey included questions regarding the family type, living arrangement, and the sources of support when it comes to their physical, emotional, financial, and decision-making needs. RESULTS: The responses from the participants showed that cancer caregiving is shared by multiple family caregivers; the major source of support for elderly cancer patients on diverse domains was their spouse; patients' reliance on their daughter(s) increased for emotional support; and patients' reliance on their son(s) stood out for financial support and decision-making support. Also, the older the patients were, the heavier their reliance was on the adult children, including sons, daughters, and daughters-in-law. CONCLUSION: Future support programs for elderly cancer patients are suggested to involve multiple family caregivers to encourage effective and efficient intervention. Also, the limitations of the current study and the suggestions for future research are discussed.

PURPOSE: The purpose of this study was to compare health-related quality of life (HRQoL) of disease-free prostate (PC), kidney (KC), and bladder cancer (BC) survivors with that of the general population. MATERIALS AND METHODS: Our study included 331 urological cancer (UC) survivors (114 PC, 108 KC, and 109 BC) aged ≥ 50 years disease-free for at least 1 year after surgery. The control group included 1,177 subjects without a history of cancer. The HRQoL was assessed using the European Organization for Research and Treatment of Cancer QLQ-C30, the Duke-UNC Functional Social Support Questionnaire, and the Patient Health Questionnaire-9. RESULTS: There was no significant difference between the groups in terms of any of the functioning sub-scales and symptoms, except significantly lower social functioning observed in BC survivors than that observed in KC survivors. Although the three groups of UC survivors showed essentially similar functioning sub-scales and symptoms when compared to the general population, PC and BC survivors showed significantly lower social functioning and a lower appetite than that observed in controls. KC survivors showed lower physical functioning, as well as higher pain and dyspnea. Although all three groups of UC survivors reported higher financial difficulties, they also reported higher perceived social support than that reported by the non-cancer control group. No statistically significant difference was observed in terms of depressive symptoms between each group of UC survivors and the general population. CONCLUSION: Disease-free survivors of the three major types of UCs showed generally similar HRQoL compared to the general population, as well as compared to each other.

PURPOSE: This study aims to investigate the trend in medical travel by non-Seoul residents to Seoul for treatment of prostate cancer and also to investigate the possible factors affecting the trend. MATERIALS AND METHODS: This study represents a retrospective cohort study using data from theKoreanNationalHealth Insurance System from 2002 to 2015. Annual trends were produced for proportions of patients who traveled according to the age group, economic status and types of treatment. Multiple logistic analysiswas used to determine factors affecting surgeries at medical facilities in Seoul among the non-Seoul residents. RESULTS: A total of 68,543 patients were defined as newly diagnosed prostate cancer cohorts from 2005 to 2014. The proportion of patients who traveled to Seoul for treatment, estimated from cases with prostate cancer-related claims, decreased slightly over 9 years (28.0 at 2005 and 27.0 at 2014, p=0.02). The average proportion of medical travelers seeking radical prostatectomy increased slightly but the increase was not statistically significant (43.1 at 2005 and 45.4 at 2014, p=0.26). Income level and performance ofrobot-assisted radical prostatectomy were significant positive factors for medical travel to medical facilities in Seoul. Combined comorbidity diseases and year undergoing surgery were significant negative factors for medical travel to medical facilities in Seoul. CONCLUSION: The general trend of patients travelling from outside Seoul for prostate cancer treatment decreased from 2005 to 2014. However, a large proportion of traveling remained irrespective of direct distance from Seoul.

PURPOSE: Our study aimed to report the annual changes in lung cancer statistics and analyze trends in sociodemographic, medical, and financial factors from 2003 to 2013 in the national database from the Korean National Health Insurance (KNHI). MATERIALS AND METHODS: Among 7,489 patients with code C34 in KNHI database, only lung cancer patients newly diagnosed after 2003 were included in the study population, for a total of 4,582 patients. Descriptive statistics were used to characterize treatment patterns and medical costs according to sociodemographic factors. RESULTS: Approximately 70% of subjects were male, and the mean age was 67 years. Around 46% of patients were over 70 years old, and 12% were over 80 years old. The medical costs were highest for patients younger than 60 and lowest for those over 80 years old. Surgery was more common in younger patients, while “no treatment” increased greatly with age. In trend analysis, the proportions of aging (p for trend < 0.001), female (p for trend=0.003), metropolitan/urban (p for trend=0.041), and lowest or highest-income patients (p for trend=0.004) increased over time, along with the prevalence of surgery as the primary treatment (p for trend < 0.001). There was also a trend with regard to change in medical costs (p for trend < 0.001), in that those of surgery and radiotherapy increased. CONCLUSION: Surgery as a curative treatment has increased over the past decade. However, the elderly, suburban/rural residents, and low-income patients were more likely to be untreated. Therefore, active measures are required for these increasingly vulnerable groups.

PURPOSE: Older patient populations commonly have cognitive impairment, which might impact decisional capacity. We examined patients and family caregivers preferences for family involvement in treatment decision making assuming different level of cognitive impairment, and sought to explore the factors associated with the preferences and the degree to which patients and family members agree on preferences. MATERIALS AND METHODS: A total of 358 elderly cancer patient and caregiver dyads were recruited from the 11 cancer centers in Korea andwere asked to express their preferences forfamily involvement in treatment decision making using hypothetical scenarios with three different levels of cognitive status (intact, mild impairment, and severe impairment). RESULTS: Both patients and family caregivers preferred greater family dominance in treatment decision makingwith the increasing the level of cognitive impairment (39.7%, 60.9%, and 86.6% for patients and 45.0%, 66.2%, and 89.7% for caregivers in each scenarios). Patient and family caregiver concordance in decisional control preference was small for all three scenarios (weighted κ=0.32, κ=0.26, and κ=0.36, respectively). Higher patient education was associated with preference for patient dominance in treatment decision in conditions of both mild and severe cognitive impairment. The association of higher patient education and patient-caregiver preference concordance was positive with intact cognition, while it was negative with severe cognitive impairment. CONCLUSION: Decision control preferences were affected by hypothesized cognitive status of the patients. Findings from our study would be helpful to develop effective strategy for optimizing family involvement in cancer treatment decision in the context of deteriorating cognitive function of the patients.

PURPOSE: The aim of this study is to investigate the criteria of biochemical recurrence (BCR) and follow-up periods and methods with and without blood and imaging test of urologic oncology before established guidelines of prostate cancer in Korea. MATERIALS AND METHODS: In December 2015, we sent the questionnaire to urologic oncologist in academic hospital and received the answer from 108 urologic oncologist (50%). Also, we analyzed the data of 1,141 patients underwent radical prostatectomy in 2005 from Korean Medical Insurance. RESULTS: In follow-up, 72 physicians (66.7%) performed blood test every 3 months, 51 physicians (47.2%) performed imaging study in case of BCR. Bone scan was the most common imaging study in the follow-up (74 physicians, 68.5%). But, bone scan was only performed in case of BCR (43 physicians, 39.8%). The criteria of BCR was PSA 0.2 ng/mL (75 physician, 69.4%), 76 physicians (70.4%) was performed different follow-up according to risk of patients. In Korean Medical Insurance data analysis, PSA were performed average 2 times every year and magnetic resonance imaging, computed tomography, Bone scan were performed average 0.1, 0.2, 0.1 times every year, respectively. CONCLUSIONS: The criteria of BCR and the follow-up of prostate cancer patients in Korea were similar Korean prostate cancer guidelines. Blood and imaging test might be increased compared to 10 years ago, it is necessary to compare the Korean Medical Insurance data between 10 years ago and present.

OBJECTIVES: Understanding factors affecting advanced stage at diagnosis is vital to improve cancer outcomes and overall survival. We investigated the factors affecting later-stage cancer diagnosis. METHODS: Patients completed self-reported questionnaires. We collected cancer stage data from medical records review. Logistic regression analyses were performed to identify factors associated with later stage cancer at diagnosis by gender. RESULTS: In total, 1,870 cancer patients were included in the study; 55.8% were men, 31.1% had more than one comorbid condition, and 63.5% had disabilities. About half of the patients were smokers, and drank alcohol, and 58.0% were diagnosed at an advanced stage. By cancer type, lung and liver cancers (both genders), prostate (men), colorectal, cervical, and thyroid cancer (women) were more likely to be diagnosed at a later stage. After controlling for socioeconomic factors, comorbidity (odds ratio [OR], 1.48 in men) and disability (OR, 1.64 in men and 1.52 in women) remained significantly associated with late-stage diagnosis. CONCLUSION: In this nationwide study, using combined information from patients and medical records, we found that male patients with comorbidities or disabilities, and female patients with disabilities were more likely to have advanced stage cancer at diagnosis. Targeted approaches by cancer type and health conditions are recommended.

OBJECTIVES: To evaluate associations between hospital volume, costs, and length of stay (LOS), and clinical and demographic outcome factors for five types of cancer resection. The main dependent variables were cost and LOS; the primary independent variable was volume. METHODS: Data were obtained from claims submitted to the Korean National Health Insurance scheme. We identified patients who underwent the following surgical procedures: pneumonectomy, colectomy, mastectomy, cystectomy, and esophagectomy. Hospital volumes were divided into quartiles. RESULTS: Independent predictors of high costs and long LOS included old age, low health insurance contribution, non-metropolitan residents, emergency admission, Charlson score > 2, public hospital ownership, and teaching hospitals. After adjusting for relevant factors, there was an inverse relationship between volume and costs/LOS. The highest volume hospitals had the lowest procedure costs and LOS. However, this was not observed for cystectomy. CONCLUSION: Our findings suggest an association between patient and clinical factors and greater costs and LOS per surgical oncologic procedure, with the exception of cystectomy. Yet, there were no clear associations between hospitals’ cost of care and risk-adjusted mortality.

PURPOSE: This study aimed to examine the following questions: to what extent do patients and caregivers perceive their family members to be avoidant of communication regarding patient's cancer, and to what extent do these perceptions interrelate; and how do such perceptions influence their own and each other's communication behaviors, communication outcome, mental health, and quality of life. MATERIALS AND METHODS: A national survey was performed with 990 patient-caregiver dyads (participation rate, 76.2%). To examine the dyadic interaction, we developed linked patient and family member questionnaires, including the Family Avoidance of Communication about Cancer (FACC) scale. RESULTS: The mean scores (standard deviations) of patient- and caregiver-perceived FACC were low at 10.9 (15.5) and 15.5 (17.5), respectively (p < 0.001), and concordance was low, a well (Spearman's rho, 0.23). Patient-perceived FACC was associated with lower levels of disclosure and behaviors of holding back communication, as well as lower levels of mental health outcome and quality of life. The same was true for caregivers (all p < 0.05). Patient-perceived FACC was associated with caregiver holding back, caregiver's depression level, and caregiver quality of life (all p < 0.05). Both patient- and caregiver-perceived FACC were independently associated with communication difficulty within the family. CONCLUSION: Future research would benefit from the measurement of FACC from both patients and caregivers, and promote family intervention to enhance openness to communication, which would be helpful for improving mental health and quality of life for both patients and caregivers.

PURPOSE: The purpose of this study was to evaluate the cancer care cost during the last year of life of patients in Korea. MATERIALS AND METHODS: We studied the breakdown of spending on the components of cancer care. Cancer decedents in 2009 were identified from the Korean Central Cancer Registry and linked with the Korean National Health Insurance Claims Database. The final number of patients included in the study was 70,558. RESULTS: In 2009, the average cancer care cost during the last year of life was US $15,720. Patients under age 20 spent US $53,890 while those 70 or over spent US $11,801. Those with leukemia incurred the highest costs (US $43,219) while bladder cancer patients spent the least (US $13,155). General costs, drugs other than analgesics, and test fees were relatively high (29.7%, 23.8%, and 20.7% of total medical costs, respectively). Analgesic drugs, rehabilitation, and psychotherapy were still relatively low (4.3%, 0.7%, and 0.1%, respectively). Among the results of multiple regression analysis, few were notable. Age was found to be negatively related to cancer care costs while income level was positively associated. Those classified under distant Surveillance, Epidemiology, and End Results stages of cancer and higher comorbidity level also incurred higher cancer care costs. CONCLUSION: Average cancer care costs varied significantly by patient characteristics. However, the study results suggest an underutilization of support services likely due to lack of alternative accommodations for terminal cancer patients. Further examination of utilization patterns of healthcare resources will help provide tailored evidence for policymakers in efforts to reduce the burdens of cancer care.

PURPOSE: Early diagnosis and an improved survival rate have emerged as important issues for cancer survivors returning to work during the prime of their working life. This study investigated the attitudes of the general public towards cancer survivors returning to work in Korea and attempted to identify the factors influencing this negative attitude. MATERIALS AND METHODS: A general public perception survey regarding cancer survivors returning to work, targeting 2,000 individuals between 40-70 years of age, was conducted as face-to-face home visit. RESULTS: The public expressed a negative attitude towards cancer survivors returning to work, in terms of both perception and acceptance. Negative perception was higher among those in metropolitan areas compared with urban/rural areas (odds ratio [OR], 1.71), with monthly incomes $4,000 (OR, 1.54), and with patient care experience compared with those without (OR, 1.41). Negative acceptance was higher among those with monthly incomes $4,000 (OR, 1.71) and those with patient care experience compared with those without (OR, 1.54). The common factors between acceptance and perception that influenced negative attitude included area of residence, patient care experience, and monthly income. CONCLUSION: This study identified negative attitudes towards cancer survivors returning to work in South Korea and the factors influencing the reintegration of cancer survivors into society. It is necessary to promote community awareness and intervention activities to enable access to community, social, and individual units for the social reintegration of cancer survivors.

PURPOSE: The aim of this study was to investigate whether aspirin use can reduce the incidence of gastric cancer in patients with hypertension or type 2 diabetes. MATERIALS AND METHODS: A total of 200,000 patients with hypertension or type 2 diabetes were randomly selected from the Korean National Health Insurance claim database. Of these, 3,907 patients who used 100 mg of aspirin regularly (regular aspirin users) and 7,808 patients who did not use aspirin regularly (aspirin non-users) were selected at a frequency of 1:2, matched by age, sex, comorbid illnesses (type 2 diabetes and hypertension), and observation periods. The incidence of gastric cancer in this cohort was then assessed during the observation period of 2004 to 2010. RESULTS: In the matched cohort, the incidence rates of gastric cancer were 0.8% (31/3,907) for regular aspirin users and 1.1% (86/7,808) for aspirin non-users, but the cumulative incidence rates were not significantly different between groups (p=0.116, log-rank test). However, in multivariate analysis, regular aspirin users had a reduced risk of gastric cancer (adjusted hazard ratio [aHR], 0.71; 95% confidential interval [CI], 0.47 to 1.08; p=0.107). Duration of aspirin use showed significant association with reduction of gastric cancer risk (aHR for each year of aspirin use, 0.85; 95% CI, 0.73 to 0.99; p=0.044), particularly in patients who used aspirin for more than 3 years (aHR, 0.40; 95% CI, 0.16 to 0.98; p=0.045). CONCLUSION: Long-term low-dose aspirin use was associated with reduced gastric cancer risk in patients with hypertension or type 2 diabetes.

PURPOSE: The aim of this study was to compare the public perceptions of the incidence rates and survival rates for common cancers with the actual rates from epidemiologic data. MATERIALS AND METHODS: We conducted a survey of Korean adults without history of cancer (n=2,000). The survey consisted of questions about their perceptions regarding lifetime incidence rates and 5-year survival rates for total cancer, as well as those of eight site-specific cancers. To investigate associated factors, we included questions about cancer worry (Lerman's Cancer Worry Scale) or cared for a family member or friend with cancer as a caregiver. RESULTS: Only 19% of Korean adults had an accurate perception of incidence rates compared with the epidemiologic data on total cancer. For specific cancers, most of the respondents overestimated the incidence rates and 10%-30% of men and 6%-18% of women had an accurate perception. A high score in "cancer worry" was associated with higher estimates of incidence rates in total and specific cancers. In cancers with high actual 5-year survival rates (e.g., breast and thyroid), the majority of respondents underestimated survival rates. However, about 50% of respondents overestimated survival rates in cancers with low actual survival rates (e.g., lung and liver). There was no factor consistently associated with perceived survival rates. CONCLUSION: Widespread discrepancies were observed between perceived probability and actual epidemiological data. In order to reduce cancer worry and to increase health literacy, communication and patient education on appropriate risk is needed.

PURPOSE: Many end-of-life care studies are based on the assumption that there is a shared definition of language concerning the stage of cancer. However, studies suggest that patients and their families often misperceive patients' cancer stages and prognoses. Discrimination between advanced cancer and terminal cancer is important because the treatment goals are different. In this study, we evaluated the understanding of the definition of advanced versus terminal cancer of the general population and determined associated socio-demographic factors. MATERIALS AND METHODS: A total of 2,000 persons from the general population were systematically recruited. We used a clinical vignette of a hypothetical advanced breast cancer patient, but whose cancer was not considered terminal. After presenting the brief history of the case, we asked respondents to choose the correct cancer stage from a choice of early, advanced, terminal stage, and don't know. Multinomial logistic regression analysis was performed to determine sociodemographic factors associated with the correct response, as defined in terms of medical context. RESULTS: Only 411 respondents (20.6%) chose "advanced," while most respondents (74.5%) chose "terminal stage" as the stage of the hypothetical patient, and a small proportion of respondents chose "early stage" (0.7%) or "don't know" (4.4%). Multinomial logistic regression analysis found no consistent or strong predictor. CONCLUSION: A large proportion of the general population could not differentiate advanced cancer from terminal cancer. Continuous effort is required in order to establish common and shared definitions of the different cancer stages and to increase understanding of cancer staging for the general population.

PURPOSE: Screening for second primary cancer (SPC) is one of the key components to survivorship care. We aim to evaluate the oncologists' experience with SPCs and assess the current practice, perceived barriers, and recommendations related to SPC screening. MATERIALS AND METHODS: A nationwide survey was conducted with a representative sample of 496 Korean oncologists. A questionnaire based on the findings from our previous qualitative study was administered. RESULTS: More than three-fourths of oncologists (76.3%), who participated in the study, had experience with SPC patients. Over half of them (51.9%) stated that it was an embarrassing experience. While the current management practice for SPC varies, most oncologists (80.2%) agreed on the necessity in proactively providing information on SPC screening. A short consultation time (52.3%), lack of guidelines and evidence on SPC screening (47.7%), and patients' lack of knowledge about SPCs (45.1%) or SPC screening (41.4%) were most frequently reported as barriers to providing appropriate care for managing SPC. Oncologists recommended the development of specific screening programs or guidelines in accordance to the type of primary cancer (65.9%), the development of an internal system for SPC screening within the hospital (59.7%) or systematic connection with the national cancer screening program (44.3%), and education of oncologists (41.4%) as well as patients (48.9%) regarding SPC screening. CONCLUSION: Many oncologists reported the occurrence of SPC as an embarrassing experience. Given the variations in current practice and the lack of consensus, further studies are warranted to develop the optimal clinical strategy to provide SPC screening for cancer survivors.

PURPOSE: In response to the challenges and difficulties imposed by rare cancers, multi-stakeholder initiatives dedicated to improving rare cancer care was launched, and several recommendations were made by professional societies. However, these primarily reflect the view of the advocates and supporters, and may not represent the views of the "average" clinician or researcher. In this study, we sought to investigate perceived difficulties with regard to rare cancer care and potential solutions endorsed by oncologists. MATERIALS AND METHODS: A representative sample of 420 oncologists recruited in 13 cancer centers participated in a nationwide survey. RESULTS: Oncologists faced various difficulties in treatment of patients with rare cancers, including the lack of clinical practice guidelines (65.7%) and personal experience (65.2%), lack of approved treatment options (39.8%), and reimbursement issues (44.5%). They were generally supportive of recent recommendations by multi-stakeholder initiatives as well as professional societies for development of clear clinical practice guidelines (66.0%), flexible reimbursement guidelines (52.9%), and a national rare cancer registry (47.4%). However, there was only moderate endorsement for referrals to high-volume centers (35.5%) and encouragement of off-label treatments (21.0%). CONCLUSION: Insights into the general attitudes of oncologists gained through our nationwide survey of representative samples would be helpful in development of clinical practices and public health policies in rare cancer treatment and research.

The number of cancer survivors is increasing dramatically. Many cancer survivors face lifetime risks associated with their cancer therapy, with a significant proportion at risk for serious morbidity and premature mortality. Concerns regarding the long-term physical, psychosocial, and economic effects of cancer treatment on cancer survivors and their families are increasingly being recognized and addressed by public and private sector. This article summarizes economic burden of cancer survivors, main post-treatment health problems including secondary primary cancer and comorbidities, health behaviors such as smoking, exercise and physical activity, nutrition, and psychosocial problems. Faced with various health and psychosocial problems specific to this population, several healthcare and policy models are being suggested to address these issues, including 'shared care model' and 'integrative supportive care service delivery system for cancer survivors'. More effort is needed to make the cancer survivorship agenda a reality, attended by a wide variety of stakeholders including researchers, patients, providers, and policy makers.
