Trend Analysis for the Choice and Cost of Lung Cancer Treatment in South Korea, 2003-2013: Dohun Kim, So Young Kim, Beomseok Suh, Jong Hyock Park; Cancer Res Treat. 2018;50(3):757-767. Published online September 4, 2017; DOI: https://doi.org/10.4143/crt.2017.050

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
We investigated changing patterns of primary treatment in Korean men with prostate cancer (PC) and impact of sociodemographic factors on treatment choice from a nationwide cohort over 10 years. Materials and Methods We conducted a cohort study of a 2% nationwide random sample of Korean National Health Insurance. A total of 1,382 patients who had undergone active treatments for newly diagnosed PC between 2003 and 2013 were included. Time trends in primary treatment of PC, including radical surgery, radiation therapy (RT), and androgen deprivation therapy (ADT) were analyzed.
Results
Total number of patients undergoing active treatments increased significantly (162%). Surgery cases showed the most significant increase, from 22.4% in 2003 to 45.4% in 2013, while the relative proportion of ADT showed a tendency to decrease from 60.3% in 2003 to 45.4% in 2013, and the relative proportion of RT was variable over 10 years (from 7.2% to 18.4%). While treatment patterns differed significantly according to age (p < 0.001) and income classes (p=0.014), there were differences in primary treatment according to residential area. In multinomial logistic regression analysis, older patients showed significant association with ADT or RT compared to surgery, while patients with higher income showed significant association with surgery. Conclusion Treatment pattern in Korean PC patients has changed remarkably over the last 10 years. Sociodemographic factors do affect the primary treatment choice. Our results will be valuable in overviewing changing patterns of primary treatment in Korean PC patients and planning future health policy for PC.

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.
