Purpose
Hospital-based clinical studies have limitations in holistic assessment of cancer treatment and prognosis, as they omit out-of-hospital patients including elderly individuals. This study aimed to investigate trends in initial treatment and corresponding prognosis of patients with exocrine pancreatic cancer (EPC) in Korea.
Materials and Methods
The Korea Central Cancer Registry data of patients with EPC from 2006 to 2017 were retrospectively reviewed. We defined the first course of treatment (FT) as the cancer-directed treatment administered within four months after cancer diagnosis according to Surveillance, Epidemiology, and End Results (SEER) program.
Results
Among 62,209 patients with EPC, localized and regional (LR) SEER stage; patients over 70 years old; and ductal adenocarcinoma excluding cystic or mucinous (DAC) accounted for 40.6%, 50.1%, and 95.9%, respectively. “No active treatment” (NT, 46.5%) was the most frequent, followed by non-surgical FT (28.7%) and surgical FT (22.0%). Among 25,198 patients with LR EPC, surgical FT increased (35.9% to 46.3%) and NT decreased (45.0% to 29.5%) from 2006 to 2017. The rate of surgical FT was inversely related to age (55.1% [< 70 years], 37.3% [70-79 years], 10.9% [≥ 80 years]). Five-year relative survival rates of LR DAC were higher after surgical FT than after NT in localized (46.1% vs. 12.9%) and regional stage (23.6% vs. 4.9%) from 2012 to 2017.
Conclusion
Less than half of overall patients with LR EPC underwent surgical FT, and this proportion decreased significantly in elderly individuals. Clinicians should focus attention on elderly patients with EPC to provide appropriate medical advice.

Purpose Primary central nervous system lymphoma (PCNSL) is an uncommon brain tumor accounting for 2%-5% of all primary brain tumors. Few population-based analyses of survival for patients with PCNSL have been conducted, particularly in Asian countries. Materials and Methods Using the Korea National Cancer Incidence Database, 1,062 cases of PCNSL newly diagnosed from 1999 to 2009 were analyzed. The crude rate, age-standardized rate (ASR), and annual percent change were calculated. To estimate the observed survival, we restricted the data to between 1999 and 2007 and followed the cases until December 2010. The overall survival was estimated using the Kaplan-Meier method, and piecewise Poisson regression model.
Results The ASR for PCNSL between 1999 and 2009 was 0.17 per 100,000, and the annual percent change from 1999 to 2009 was 8.8% (p < 0.001). The ASR of males was higher than that of females, and the older groups (60s or over) showed the largest increase in incidence rates. For all ages, the five-year survival from PCNSL was 29.9% between 1999 and 2007. Survival from PCNSL is known to show strong association with age at diagnosis. Conclusion These results are similar to those of previous studies. Our findings may be helpful to clinicians and patients in determining long-term prognoses for PCNSL.

Purpose We conducted a nationwide study to assess the incidence and treatment patterns of extremity soft tissue sarcoma (STS) in South Korea.
Materials and Methods The nationwide incidence and treatment patterns of extremity STS were assessed using two nationwide databases, the Korea National Cancer Incidence (KNCI) database and the Health Insurance Review and Assessment Service (HIRA) database.
Results A total of 1,236 patients were newly diagnosed with extremity STS during the 3-year study period, from 2009 to 2011. The annual incidence of extremity STS in the Korean population was approximately 0.9 per 100,000 people with a male bias that increased with age and was especially pronounced amongst individuals aged > 80 years. Approximately 7% of patients did not receive any treatment, and surgical excision was performed for 85% of those who were treated.
Conclusion This is the first nationwide study of the incidence and treatment patterns of extremity STS in Korea using two national databases (KNCI and HIRA), which include the entire Korean population. The results of this study may be useful for future planning and management of STS, at the national level.

PURPOSE The Korea Central Cancer Registry (KCCR) program completed a nationwide hospital-based cancer registry to provide basic statistical data on cancer incidence. MATERIALS AND METHODS In 2000, 131 hospitals participated in the KCCR program. All cancer registry data, which were submitted by the participating hospitals during the year, were reviewed and analyzed by the committee members. RESULTS Of the 94,474 cases that were registered, 7,735 (8.2%) duplication cases were excluded. Of the remaining 86,739 cases, 2,893 cases (3.3%) of carcinoma in situ (morphology code/2) were excluded, leaving a final total of 83,846 cases for analysis, 48,005 (57.3%) male and 35,841 (42.7%) female. The leading age group was 60-64years (15.1%). The six leading primary cancer sites in the order of their relative frequency were the stomach (20.8%), lung (12.2%), liver (12.2%), colorectum (10.3%), breast (6.5%), and uterine cervix (4.5%). In males, the three leading primary cancer sites were the stomach (24.5%), liver (16.3%), and lung (16.3%). In females, the stomach (15.8%), breast (15.1%), and uterine cervix (10.6%). Among the 1,126 cases of childhood malignancies, leukemia (32.7%) was the most common cancer type. CONCLUSION We report our analysis of the KCCR data from 131 nationwide hospitals during 2000.
