Background: Geriatric assessment (GA) is recommended to detect multiple problems in older patients with cancer. However, full GA is resource-consuming, necessitating screening tools to select appropriate patients who need full GA.
Methods: To design a novel screening tool, a development cohort was constructed from 1284 patients who received GA from May 2004 to April 2007. Items representing each domain were selected according to sensitivity (SS) and specifi city (SF). Of the selected items, the fi nal questions were chosen by panels of oncologists and geriatri- cians to encompass all domains and also by feasibility and use with cancer patients.
Screening questions were validated in a separate cohort of 98 cancer patients Results: The median age of patients in the development cohort was 77 y. Abnormal GA, defi ned as defi cits in at least 2 domains, was identifi ed in 71.4% of patients. The KG-7 consisted of 7 items representing each domain. KG-7 had a maximal area under the curve (AUC) of 0.93 (95% confi dence interval (CI) 0.92-0.95) in the prediction of abnormal GA. The cut-off value was decided at 5.5 points, with a SS of 95.0%, SF of 59.2%, positive predictive value (PPV) of 85.3%, and negative predictive value (NPV) of 82.6%. In the validation cohort, the AUC was 0.82 (95% CI 0.73-0.90), and the SS, SF, PPV, and NPV were 89.5%, 48.6%, 77.3%, and 75.0%, respectively. Furthermore, patients with higher KG-7 scores showed signifi cantly longer overall survival (OS) in the development and validation cohorts.
Conclusions: The KG-7 showed high SS and NPV to predict abnormal GA. The KG-7 also predicted OS. A prospective validation study is underway currently to evaluate the usefulness of the KG-7 as a screening tool in older patients with cancer.

Background: Terminally ill patients or those with terminal cancer are often excluded in the loop of end-of-life (EOL) discussion in Korea. Further, healthcare professionals have diffi culty engaging in such communication in a variety of healthcare contexts. A communication model for EOL care planning is demanding in Korea.
To solicit professional opinions on communication with terminal cancer patients and their family caregivers and to develop a communication model for EOL care planning compatible with clinical environment in Korea.
Methods: Using focus group interview, six doctors and fi ve nurses who provide EOL care for terminal cancer patients in acute hospital settings or hospice care facility from distinct provinces of Korea participated in this study.
Results: Five themes emerged regarding EOL care planning that included right time, a responsible professional, preparedness for breaking bad news, content of EOL care dis- cussion, and implementation of EOL care decisions. These themes were based for the development of a communication algorithm for EOL discussion among patients with terminal cancer (Figure 1), in which a structural communication steps for delivering a terminal prognosis was specifi ed at the phase of preparedness beginning with deter- mination of a patient decision-making capability, followed by a patient perception of his/her condition, a patient’s wish to know, family decision-making dynamics, and a patient’s and/or family’s readiness for EOL discussion.
Conclusions: It is suggested that the proposed context-oriented communication al- gorithm be communication supporting guidelines for EOL discussion and accordingly, facilitate meaningful improvements in EOL care in clinical practice.

Background: The ratio of involved to retrieved lymph nodes (LNR) is suggested as a prognostic factor in operable breast cancer. However, there are confl icting results re- garding its clinical signifi cance after neoadjuvant chemotherapy. We investigated the prognostic value of LNR with a thorough evaluation of potential prognostic factors in a large cohort constructed from Health Insurance Review and Assessment Service database of Korea.
Methods: This retrospective analysis is based on the data of 814 patients with clinical stage II/III breast cancer treated with four cycles of adriamycin/cyclophosphamide followed by four cycles of docetaxel before surgery. We evaluated the clinical signifi - cance of the LNR (3 categories: Low, 0-0.20 vs. Intermediate, 0.21-0.65 vs. High, 0.66 -1.00) using Kaplan-Meier method, log-rank test, and Cox proportional hazard regres- sion model.
Results: A total of 799 patients underwent breast surgery (Median age 45, range 16- 74; Mastectomy 369, Lumpectomy 380, and Others 50). Axillary lymph node dissec- tion was performed in 704 (88.1%) patients. Pathologic complete response (pCR) was achieved in 129 (16.1%) of 799 patients (HR+/HER2-, 34/373 [9.1%]; HER2+, 45/210 [21.4%]; TNBC 50/216 [23.1%]). The mean numbers of involved LN and retrieved LN were 2.70 (range 0-42) and 13.98 (range 1-64), respectively. The mean LNR was 0.17
