Validating the Korean Geriatric Assessment Tool in Elderly Multiple Myeloma Patients: A Multicenter Study: Ji Yun Lee, Sang-A Kim, Youngil Koh, Ho-Young Yhim, Gyeong-Won Lee, Chang-Ki Min, Young Rok Do, Hyo Jung Kim, Sung Hwa Bae, Hyeon-Seok Eom, Sung-Hoon Jung, Hyunkyung Park, Seung-Hyun Nam, Ji Hyun Lee, Sung-Hyun Kim, Hyun Jung Lee, Young Seob Park, Soo-Mee Bang; Received January 15, 2025 Accepted February 20, 2025 Published online February 21, 2025; DOI: https://doi.org/10.4143/crt.2025.066 [Accepted]

Abstract PDF: Purpose
This study evaluates the Korean Cancer Study Group Geriatric Score-7 (KG-7) frailty screening tool's effectiveness in elderly multiple myeloma (MM) patients to prevent under and over-treatment.
Materials and Methods
This prospective pilot cohort study included 100 elderly patients aged 70 and older with newly diagnosed MM who had not undergone transplantation from August 2020 to January 2022.
Results
The median age was 77 years, and 73% of patients were classified at International Staging System (ISS) stages 2 or 3. Using a 5-point cutoff on the KG-7 index (non-frail, score ≥ 5; frail, score < 5), 31% were categorized as frail. After a median follow-up of 26.8 months, the 3-year overall survival rate was 73.0%. There was no statistically significant association between any frailty index and the risk of death. However, frail patients defined by the simplified frailty index (HR, 2.49; 95% CI, 1.09–5.95; p=0.030) and by KG-7 (HR, 2.43; 95% CI, 1.03–5.86; p=0.043) had a significantly higher risk of grade 3–4 non-hematologic toxicity, whereas the IMWG definition did not. Over a 24-month tracking period, vulnerability as measured by KG-7 either improved or deteriorated.
Conclusion
The pilot study, which had a limited number of participants, did not demonstrate KG-7’s effectiveness in predicting survival; however, it successfully predicted severe non-hematologic toxicities. We plan to conduct larger studies in elderly MM patients to determine whether KG-7 can help tailor their treatment regimens.

To Use or Not to Use: Temozolomide in Elderly Patients with IDH Wild-Type MGMT Promoter Unmethylated Glioblastoma Treated with Radiotherapy: Chan Woo Wee, Joo Ho Lee, Hye In Lee, Jina Kim, Jong Hee Chang, Seok-Gu Kang, Eui Hyun Kim, Ju Hyung Moon, Jaeho Cho, Chul-Kee Park, Chae-Yong Kim, Kihwan Hwang, Hong In Yoon, In Ah Kim; Received September 27, 2024 Accepted November 8, 2024 Published online November 11, 2024; DOI: https://doi.org/10.4143/crt.2024.945 [Epub ahead of print]

Abstract PDF PubReader ePub: Purpose
This study aimed to identify a specific subgroup of patients among elderly glioblastoma patients aged 70 years or older with unmethylated O6-methylguanine-DNA methyltransferase promoters (eGBM-unmethylated) who would significantly benefit from the addition of temozolomide (TMZ) to radiotherapy (RT).
Materials and Methods
Newly diagnosed patients with Isocitrate dehydrogenase wild-type eGBM-unmethylated treated with RT were included in this multicenter analysis (n=182). RT dose was 45 Gy in 15 fractions (62.3%), 60 Gy in 30 fractions, or 61.2 Gy in 34 fractions. For patients treated with RT plus TMZ (60.4%), TMZ was administered concurrently with RT, followed by six adjuvant cycles. The primary endpoint was overall survival.
Results
During a median follow-up of 11.3 months for survivors, the median survival was 12.2 months. The median survival duration significantly improved with the addition of TMZ to RT compared with that with RT alone (13.6 months vs. 10.5 months, p=0.028). In the multivariable analysis adjusted for clinical, radiological, and genetic biomarkers, the addition of TMZ significantly improved overall survival (hazard ratio, 0.459; p=0.006). In subgroup analysis, median survival was especially improved by 4-5 months in patients with residual disease (p < 0.001), Karnofsky performance status ≥ 60 (p=0.033), and age ≤ 75 years (p=0.090). A significant benefit of TMZ was noted only in patients with two or three of the above factors (median survival, 14.1 months vs. 10.5 months; p=0.014).
Conclusion
The addition of TMZ significantly improved the survival of patients with eGBM-unmethylated treated with RT. The suggested criteria for the specific subgroup in these patients warrant external validation for clinical application.

Choosing Wisely between Radiotherapy Dose-Fractionation Schedules: The Molecular Graded Prognostic Assessment for Elderly Glioblastoma Patients: Hye In Lee, Jina Kim, In Ah Kim, Joo Ho Lee, Jaeho Cho, Rifaquat Rahman, Geoffrey Fell, Chan Woo Wee, Hong In Yoon; Cancer Res Treat. 2025;57(2):378-386. Published online September 11, 2024; DOI: https://doi.org/10.4143/crt.2024.680

Abstract PDF Supplementary Material PubReader ePub: Purpose
This study aimed to develop a graded prognostic assessment (GPA) model integrating genomic characteristics for elderly patients with glioblastoma (eGBM), and to compare the efficacy of different radiotherapy schedules.
Materials and Methods
This multi-institutional retrospective study included patients aged ≥ 65 years who underwent surgical resection followed by radiotherapy with or without temozolomide (TMZ) for newly diagnosed eGBM. Based on the significant factors identified in the multivariate analysis for overall survival (OS), the molecular GPA for eGBM (eGBM-molGPA) was established.
Results
A total of 334 and 239 patients who underwent conventionally fractionated radiotherapy (CFRT) and hypofractionated radiotherapy (HFRT) were included, respectively, with 86% of patients receiving TMZ-based chemoradiation. With a median follow-up of 17.4 months (range, 3.3 to 149.9 months), the median OS was 18.7 months for CFRT+TMZ group, 15.1 months for HFRT+TMZ group, and 10.4 months for radiotherapy alone group (CFRT+TMZ vs. HFRT+TMZ: hazard ratio [HR], 1.52; p < 0.001 and CFRT+TMZ vs. radiotherapy alone: HR, 2.52; p < 0.001). In a combined analysis with the NOA-08 and Nordic trials, CFRT+TMZ group exhibited the highest survival rates among all treatment groups. The eGBM-molGPA, which integrated four clinical and three molecular parameters, stratified patients into low-, intermediate-, and high-risk groups. CFRT+TMZ significantly improved OS compared to HFRT+TMZ or radiotherapy alone in the low-risk (p=0.023) and intermediate-risk groups (p < 0.001). However, in the high-risk group, there was no significant difference in OS between treatment options (p=0.770).
Conclusion
CFRT+TMZ may be more effective than HFRT+TMZ or radiotherapy alone for selected eGBM patients. The novel eGBM-molGPA model can guide treatment selection for this patient population.

Active Treatment Improves Overall Survival in Extremely Older Non–Small Cell Lung Cancer Patients: A Multicenter Retrospective Cohort Study: Su Yeon Lee, Yoon-Ki Hong, Wonjun Ji, Jae Cheol Lee, Chang Min Choi, Korean Association for Lung Cancer, Korea Central Cancer Registry; Cancer Res Treat. 2021;53(1):104-111. Published online October 5, 2020; DOI: https://doi.org/10.4143/crt.2020.894

Abstract PDF Supplementary Material PubReader ePub

Purpose
As the aging of society progresses, the proportion of extremely older lung cancer patients has also increased; However, studies of these patients with non–small cell lung cancer are limited. Therefore, we investigated the initial treatment modalities and survival outcomes for patients aged 80 years or over.
Materials and Methods
We included a multicenter retrospective cohort from the Korean Association for Lung Cancer Registry, which surveys 10% of the newly diagnosed lung cancer patients across 52 hospitals in Korea. We analyzed and compared the 2014–2016 data of the non–small cell lung cancer patients aged ≥ 80 years and those aged < 80 years.
Results
Of the 6,576 patients reviewed, 780 patients were aged ≥ 80 years, and 5,796 patients were aged < 80 years. In the patients aged ≥ 80 years, surgery and radiation therapy resulted in longer patient survival among those with a resectable tumor (stage I–II) than the best supportive care (median survival, not reached [surgery] vs. 32.2 months [radiation therapy] vs. 11.43 months [best supportive care]). The duration of survival in patients with advanced-stage (IV) lung cancers was higher after chemotherapy than after the best supportive care (median survival, 8.63 months vs. 2.5 months). Patients with stage IV adenocarcinoma who received targeted therapy had better survival than those who did not (median survival, 9.0 months vs. 4.3 months).
Conclusion
Even in extremely older patients, active treatments, such as surgery, radiation therapy, and chemotherapy, can result in better survival outcomes than the best supportive care.

Omitting Adjuvant Radiotherapy for Hormone Receptor‒Positive Early-Stage Breast Cancer in Old Age: A Propensity Score Matched SEER Analysis: Yi-Jun Kim, Kyung Hwan Shin, Kyubo Kim; Cancer Res Treat. 2019;51(1):326-336. Published online May 10, 2018; DOI: https://doi.org/10.4143/crt.2018.163

Abstract PDF PubReader ePub

Purpose
The purpose of this study was to investigate the non-inferiority of omitting radiotherapy (RT) after breast-conserving surgery (BCS) for hormone receptor (HR)‒positive T1N0 breast cancer in elderly women.
Materials and Methods
From 2004 to 2014, HR-positive T1N0 breast cancer patients aged 50 years or older and receiving BCS were retrieved from the Surveillance, Epidemiology, and End Results 18 database. After propensity score matching between the no-RT and RT groups, univariate and multivariate analyses were performed. Identified prognostic factors were used to stratify the risk groups. In each risk group, 10-year cancer-specific survival (CSS) rates were compared between the no-RT and RT groups.
Results
After propensity score matching, the numbers of patients in the no-RT and RT groups were both 18,586. For patients who satisfied both a tumor size of 1-10 mm and a tumor grade of 1-2, omitting RT did not decrease the CSS rate at any age group, ranging from ≥ 50 to ≥ 85 years; for patients aged ≥ 50 years, the 10-year CSS rates in the no-RT and RT groups were 97.2% and 96.8%, respectively (adjusted hazard ratio, 0.862; p=0.312). However, for patients with a tumor size of 11-20 mm or tumor grade of 3-4, RT significantly increased the CSS rate irrespective of age.
Conclusion
RT after BCS for HR-positive T1N0 breast cancer in elderly women might be omitted without causing a decrease in the CSS rate, but only in patients who satisfy both a small tumor size (≤ 10 mm) and low tumor grade (1-2).

The Characteristics and Survival Outcomes in Patients Aged 70 Years and Older with Nasopharyngeal Carcinoma in the Intensity-Modulated Radiotherapy Era: Ya-Nan Jin, Wang-Jian Zhang, Xiu-Yu Cai, Mei-Su Li, Wayne R. Lawrence, Si-Yang Wang, Dong-Mei Mai, Yu-Yun Du, Dong-Hua Luo, Hao-Yuan Mo; Cancer Res Treat. 2019;51(1):34-42. Published online February 6, 2018; DOI: https://doi.org/10.4143/crt.2017.551

Abstract PDF PubReader ePub

Purpose
We aim to examine nasopharyngeal carcinoma (NPC) characteristics and survival outcomes in patients aged 70 years and older in the intensity-modulated radiotherapy (IMRT) era.
Methods
and Materials From 2006 to 2013, 126 non-metastatic NPC patients aged ≥ 70 years who were treated with IMRT +/‒ chemotherapy were included. Adult Comorbidity Evaluation 27 (ACE-27) was used to measure patient comorbidities. The overall survival (OS) and cancer-specific survival (CSS)were calculatedwith the Kaplan-Meier method, and differenceswere compared using the log-rank test. The Cox proportional hazards model was used to carry out multivariate analyses.
Results
For the entire group, only two patients (1.6%) presented stage I disease, and up to 84.1% patients had stage III-IVB disease. All patients had a comorbidity score of 0 in 24 (19.0%), 1 in 45 (35.7%), 2 in 42 (33.3%), and 3 in 15 (11.9%) patients. The main acute grade during radiotherapy was 3-4 adverse events consisting of mucositis (25.4%), bone marrow suppression (16.7%), and dermatitis (8.7%). After treatment, four patients (3.2%) developed temporal lobe injury. Five-year CSS and OS rates were 67.3% (95% confidence interval [CI], 58.6% to 77.4%) and 54.0% (95% CI, 45.6% to 63.9%), respectively. Five-year OS was significantly higher for ACE-27 score 0-1 than ACE-27 score 2-3 (72.9% and 39.9%, respectively; p < 0.001). Multivariate analyses showed ACE-27 score 0-1 was significantly associated with superior OS (hazard ratio [HR], 3.02; 95% CI, 1.64 to 5.55; p < 0.001). In addition, the rate of OS was higher for stage I-III than that of stage IV, with borderline significance (HR, 1.67; 95% CI, 0.99 to 2.82; p=0.053). But no significant advantage was observed in OS when chemotherapy was used (p > 0.05).
Conclusion
Our findings suggest IMRT +/– chemotherapy has a manageable toxicity and provides an acceptable survival in patients aged ≥ 70 years with NPC. ACE-27 score was significantly associated with survival outcomes in this group population.

Published online June 9, 2017; DOI: https://doi.org/10.4143/crt.2017.172

Abstract PDF PubReader ePub

Purpose
The treatment strategy for elderly patients older than 80 years with diffuse large B-cell lymphoma (DLBCL) has not been established because of poor treatment tolerability and lack of data.
Materials and Methods
This multicenter retrospective study was conducted to investigate clinical characteristics, treatment patterns and outcomes of patients older than 80 years who were diagnosed with DLBCL at 19 institutions in Korea between 2005 and 2016.
Results
A total of 194 patients were identified (median age, 83.3 years). Of these, 114 patients had an age-adjusted International Prognostic Index (aaIPI) score of 2-3 and 48 had a Charlson index score of 4 or more. R-CHOP was given in 124 cases, R-CVP in 13 cases, other chemotherapy in 17 cases, radiation alone in nine cases, and surgery alone in two cases. Twenty-nine patients did not undergo any treatment. The median number of chemotherapy cycles was three. Only 37 patients completed the planned treatment cycles. The overall response rate from 105 evaluable patientswas 90.5% (complete response, 41.9%). Twentynine patients died due to treatment-related toxicities (TRT). Thirteen patients died due to TRT after the first cycle. Median overall survival was 14.0 months. The main causes of death were disease progression (30.8%) and TRT (27.1%). In multivariate analysis, overall survival was affected by aaIPI, hypoalbuminemia, elevated creatinine, and treatment.
Conclusion
Age itself should not be a contraindication to treatment. However, since elderly patients show higher rates of TRT due to infection, careful monitoring and dose modification of chemotherapeutic agents is needed.

Meta-Analysis

Adjuvant Chemotherapy for Advanced Gastric Cancer in Elderly and Non-elderly Patients: Meta-Analysis of Randomized Controlled Trials: Seong-Hwan Chang, Soo-Nyung Kim, Hye Jung Choi, Misuk Park, Rock Bum Kim, Se-Il Go, Won Sup Lee; Cancer Res Treat. 2017;49(1):263-273. Published online July 5, 2016; DOI: https://doi.org/10.4143/crt.2016.054

Abstract PDF PubReader ePub

Purpose
This study evaluated the benefits of adjuvant chemotherapy on elderly patients with advanced gastric cancer (AGC) using meta-analysis of well-designed randomized controlled clinical studies.
Materials and Methods
PubMed, Embase, and Cochrane were searched to retrieve clinical studies evaluating the benefits of adjuvant chemotherapy in the elderly with AGC. Hazards ratios (HRs) with 95% confidence intervals (CIs) were pooled across studies using a fixed-effects model.
Results
Two studies were included in this meta-analysis to estimate HR for the overall survival (OS), and relapse-free survival (RFS) between adjuvant chemotherapy and surgery in elderly and non-elderly patients. HR for OS in the elderly and non-elderly was 0.745 (95% CI, 0.552 to 1.006, p=0.055) and 0.636 (95% CI, 0.522 to 0.776; p < 0.001), respectively, which showed no heterogeneity regarding HR between the two groups (p_interaction=0.389). HR for RFS in the elderly and non-elderly was 0.613 (95% CI, 0.466 to 0.806; p < 0.001) and 0.633 (95% CI, 0.533 to 0.753; p < 0.001), respectively (p_interaction=0.846).
Conclusion
Meta-analysis suggests that the benefit of adjuvant chemotherapy to the elderly is not big enough to reach statistical significance while the HR for OS is less than 1 (0.745) and no heterogeneity are observed regarding the HR between the elderly and non-elderly patients.

Purpose
Gastric cancer is the third-leading cause of cancer-related death in Korea. As the Korean population is ageing, the number of extremely old patients with this disease is increasing. This study examined the clinicopathological characteristics of gastric cancer in extremely old (over 85 years) patients who received treatment or conservative observations and compared the treatment outcomes according to the treatment modality.
Materials and Methods
A total of 170 patients over 85 years of age were diagnosed with gastric cancer. Of these, 81 underwent treatment for gastric cancer and 89 received conservative observations. The clinicopathological characteristics of the treatment and conservative groupswere compared.
Results
The mean age of the patients was 86.5 years. The conservative group included significantly more patients with older ages, macroscopically advanced cancer and upper-middle located cancer. The overall survival rate of the treatment group was significantly higher than that of the conservative group. The disease-specific mortality rate was significantly lower in the treatment group than in the conservative group. Multivariate analysis revealed the clinical course, alarm sign, and macroscopic classification to be independent prognosis factors.
Conclusion
By itself, the chronological age should not be used as a strategy to determine whether treatmentwill be administered for gastric cancer. Patientswho have early gastric cancer or lower-risk preexisting comorbidities should not be discouraged from treatment, even if they are older than 85 years.

Purpose
The purpose of this study was to assess the tumor characteristics and long-term clinical outcomes of adjuvant treatments after surgery with a curative aim for patients with breast cancer who are 65 years and older. Materials and Methods Patients with breast cancer who underwent curative surgery from 2000 to 2009 were analyzed (n=4,388). Tumor characteristics and survival outcome were compared by dividing the patients into two age groups (< 65 and ≥ 65 years old). The Kaplan-Meier method was used for comparison of survival rates by log-rank test, and a Cox regression model was used to examine the effect of variables.
Results
Among 4,388 patients with invasive breast cancer, 317 patients (7.2%) were 65 years or older and the median age of all patients was 47 years (range, 18 to 91 years). Tumor characteristics were similar between the two age groups, but the older patients were treated less often with adjuvant treatments. During a median follow-up period of 122 months, recurrence-free survival (RFS) was equivalent for patients 65 years and older compared to younger patients, but significantly worse in overall survival (OS) and breast cancer–specific survival (BCSS) (5-year OS, 94.3% vs. 90.5%; p < 0.001 and 5-year BCSS, 94.7% vs. 91.8%; p=0.031). In the multivariate model, age ≥ 65 years old was identified as an independent risk factor for OS and RFS. Conclusion Elderly breast cancer appeared to have worse outcomes with very low prevalence in Korea, despite similar tumor characteristics. More active adjuvant therapies would have a role for aggressive subtypes for fit, elderly patients.

Abstract PDF PubReader ePub

PURPOSE
As the number of elderly patients diagnosed with non-small cell lung carcinoma (NSCLC) increases, the number of these patients receiving chemotherapy also increases. However, limited data exists regarding the use of chemotherapy in advanced NSCLC patients who are 75 years of age or older.
MATERIALS AND METHODS
Between May 2002 and October 2008, data for 48 advanced NSCLC patients who were 75 years of age or older who had been treated with chemotherapy were retrospectively analyzed.
RESULTS
The median age of study participants at the time of first line chemotherapy was 76 years (range, 75 to 87 years) and their median Charlson comorbidity index was 2 (range, 1 to 4). Of the total 48 patients, 43 patients (90%) were treated by platinum-based doublet as a first line chemotherapy regimen. Median progression free survival for first line chemotherapy was 5.7 months (95% confidence interval [CI], 4.93 to 6.47 months) with an overall response rate of 33.3%. After first line chemotherapy, only 14 of the 48 patients (29.2%) received second line chemotherapy. The median overall survival (OS) for these patients was 8.2 months (95% CI, 4.44 to 11.96 months). Multivariate analysis results indicated that female gender and having received second-line or more chemotherapy were independent prognostic factors for increased OS for all 48 patients. Charlson Index was not a significant independent prognostic factor for survival. There were 9 treatment related deaths due to infectious causes (18.8%).
CONCLUSION
Patients 75 years of age or older with advanced NSCLC may obtain clinical benefit from the administration of platinum-based doublet or single agent chemotherapy. However, oncologists must consider the aspect of safety in relation to the clinical benefits when managing this patient group.

PURPOSE
This study aimed to analyze the efficacy and toxicity of gemcitabine plus platinum chemotherapy for patients aged 70 years or older with advanced non-small-cell lung cancer (NSCLC).
MATERIALS AND METHODS
We reviewed the records of stage IIIB, IV NSCLC patients or surgically inoperable stage II, IIIA NSCLC patients who were aged 70 years or older when treated with gemcitabine (1,250 mg/m2) plus cisplatin (75 mg/m2) or carboplatin (AUC5) chemotherapy from 2001 to 2010 at Seoul St. Mary's Hospital, Uijeongbu St. Mary's Hospital and St. Vincent's Hospital. Gemcitabine was administered on days 1 and 8, and cisplatin or carboplatin was administered on day 1. Treatments were repeated every 3 weeks for a maximum of 4 cycles.
RESULTS
The median age of the 62 patients was 73.5 years (range, 70 to 84 years). Forty-one (66%) patients exhibited comorbidity. The mean number of treatment cycles was 3.9. The compared average relative dose intensity of gemcitabine plus platinum chemotherapy was 84.8%. The median progression-free survival and overall survival (OS) were 5.0 months and 9.4 months, respectively. Reduced Eastern Cooperative Oncology Group (ECOG) performance status (none vs. > or =1) and weight loss (<5% vs. > or =5%) after treatment were found to have a significant effect on OS (p=0.01).
CONCLUSION
Gemcitabine plus platinum chemotherapy is an effective treatment option with an acceptable level of toxicity in patients aged 70 years or older with good performance status in advanced NSCLC.

Purpose

Although platinum based chemotherapy is known to improve the survival duration for the patients with non-small cell lung cancer, the role of platinum for elderly patient is not yet clear. We administered gemcitabine and carboplatin combination therapy to elderly patients with NSCLC. The aim of this study was to evaluate the efficacy and toxicities of this regimen for elderly patients.

Materials and Methods

The eligibility criteria were as follows: pathologically confirmed NSCLC, an age ≥65 years, advanced disease with stage IIIB or IV and the patients were chemotherapy-naive. The treatment regimen was as follows; gemcitabine 1,000 mg/m² was administered on days 1 and 8 and carboplatin AUC=5 was administered on day 1. This regimen was repeated every 3 weeks. The efficacy was evaluated in terms of the response rate, the time to progression and the overall survival duration.

Results

From Dec 2001 to Feb 2005, a total of 20 patients were entered into this study. The median patient age was 68 years (range: 65~75). 19 patients were evaluable for their treatment response. A partial response was obtained in 8 patients (response rate: 42.1%, 95% CI: 19.4~64.8%). The median time to progression and the survival duration were 136 days and 453 days, respectively. Among a total of 65 cycles of treatment, grade 3 or 4 leukopenia and thrombocytopenia were observed in 7.7% and 13.9% of the cycles, respectively. Grade 3 or 4 vomiting was observed in 7.7% of the cycles. Grade 3 skin rash developed in 1.5% of the cycles. 1 patient died of septic shock after chemotherapy.

Conclusions

Gemcitabine and carboplatin combination chemotherapy was relatively safe and effective for treating elderly patients with NSCLC.

Abstract PDF

PURPOSE
This study was conducted to estimate the incidence, mortality and survival rate of stomach cancer in elderly people in Korea. MATERIALS AND METHODS: The source population was a Korean Elderly Phamacoepidemiologic Cohort (KEPEC), who were 65 years of age or older and living in Busan metropolitan city and Gyeongsangnam province, Korea. A subcohort of 38, 443 persons without stomach cancer were identified before enrolling the KEPEC. The stomach cancer incidence cases were detected from three different sources, the medical claims database of the Korea Medical Insurance Corporation (KMIC), the Korea Central Cancer Registry (KCCR), and the Busan Cancer Registry (BCR). A hospital survey for abstracting the relevant information to confirm the final diagnosis of the potential cases from the medical claims database was conducted. A medical oncologist reviewed the data to confirm the final diagnoses and the date of onset. The mortality cases due to stomach cancer were detected from the mortality database at the National Statistical Office. The incidence rate, the survival rate and the mortality rate of stomach cancer and their 95% confidence intervals were estimated using SAS Windows ver. 8.1. RESULTS: There were 338 confirmed stomach cancer cases in the KEPEC between 1 January 1994 and 31 December 1998. The age-standardized incidence rate of stomach cancer in the Korean elderly population was estimated to be 351.4 per 100, 000 person-years in males and 122.6 per 100, 000 person-years in females. In addition, 272 stomach cancer death cases were detected in the KEPEC between 1 Jan. 1994 and 31 Dec. 1998. The age-standardized mortality rate of stomach cancer to the Korean elderly population was estimated to be 268.5 per 100, 000 person-years in males and 93.7 per 100, 000 person-years in females. The one-year survival rate was 62.1% in males and 63.0% in females, which was considered to be statistically similar. The three-year survival rate was 38.9% in males and 40.9% in females. The five-year survival rate was 34.8% in males and 34.7% in females. CONCLUSION: The age-standardized male stomach cancer incidence rate and mortality rate to the Korean population were approximately three times higher than in female. However, there was little significant difference between males and females in terms of the overall survival rates. These results may be useful for planning a health policy for preventing and managing stomach cancer in Korea.
