PURPOSE: Although adjuvant chemotherapy after resection of gastric cancer is a popular practice in Korea, there are still controversies about the effectiveness of the treatment. The fact that the relatively less effective drugs have been used and the rarity of large-scaled controlled studies may be partially responsible for the controversies. FP(5-FU, Cisplatin) combination is one of the most active regimen against advanced gastric cancer, consistently showing a response rate of 50~60%. We tried the FP chemotherapy as an adjuvant treatment for high-risk patients after curative resection of gastric cancer. MATERIALS AND METHODS: Between February 1992 and June 1996, 35 patients with completely resected high-risk gastric cancer(postoperative stage III or IV except thase with M1) received six courses of FP chemotherapy. Endpoints were toxicities of treatment, relapse free survival, and overall survival. RESULTS: With a median follow-up time of 17.1 months, Kaplan-Meier estimates of 2-year overall survival was 63.3% and relapse free survival estimates was 49%. There were no differences between stage III and IV patients in terms of overall survival or relapse free survival. Hematologic and non-hematologic toxicities were tolerable for most of the patients. CONCLUSION: Postoperative FP combination chemotherapy was tolerable for patients with high-risk(stage III and IV) gastric cancer. It is too early to determine the long term survival rates for this patients, but 2-year overall and relapse free survival were comparable to that of historical non-cisplatin containing regimens. Randomized phase III studies are warranted.

The roentgenograms following arthroscopic ACL reconstruction show the enlargement of bone tunnels. Many authors hypothesized the cause of the tunnel enlargement, either mechanical or biological causes. The purpose of this study was to find the factors which affected the enlargement of the tibial tunnel following arthroscopic ACL reconstruction with bone-patellar tendon-bone or hamstring tendon. Sixty patients were reviewed retrospectively for radiographic measurement of tibial tunnel at post-operative one year (27 patients received bone-patellar tendon-bone autograft, 12 patients received bone-patellar tendon-bone autograft and Kennedy LAD-ligament augmentation device, 21 patients received Semitendinosus and Gracilis tendons with Endobutton). Roentgenographic anteroposterior and lateral films were checked and the tunnel was measured by two independent observers using a digital caliper. Statistical analysis was performed using a one-way analysis of variance (ANOVA) and t-test. The tibial tunnel enlargement was only related to the position of the fixation of the tibial tunnel. We concluded that tibial tunnel enlargement following arthroscopic ACL reconstruction is attributed to the mechanical effect rather than the properties of grafts and the clinical results.

In anterior cruciate ligament (ACL) deficient knee, several treatment methods were recommended. Recently, arthroscopic reconstruction is widely used as the best treatment method. As the graft materials, bone-patellar tendon-bone (BPB) unit is a gold standard material. Whereas, it has many problems. The purpose of this study was to introduce the new arthroscopic ACL reconstruction technique with quadrupled semitendinosus tendon and Endobutton and to evaluate its results. Twenty one patients were prospectively reviewed after ACL reconstruction with quadrupled semitendinosus tendon and Endobutton at one year post-operation. The surgery was performed in the series of graft tendon harvest, graft preparation, tunnel drilling and Endobutton fixation. The outcomes showed improved knee functions. Endobutton technique with quadrupled semitendinosus tendon is useful method for the arthroscopic ACL reconstruction. Stability and functional outcomes were similar to those with patellar tendon but it showed less donor site morbidity, less pitfall of fixation and simple procedure.

Authors investigated the possible role of intravascular hypercoagulable states on the etiology of Kegg-Clave-Perthes diesease. Forty-five patients with Legg-Clave-Perthes disease(31 avascular stages and 14 reossification stages) and twenty-two normal control patients were subjected to study for evaluation of coagulation and fibrinolysis system by means of the tests which included antiphospholipid antibody(APA), Protein C, Protein S and antithrombin- III (AT- III) for evaluation of coagulation system, and tissue type PIasminogen activator(tPA), Plasminogen activator inhibitor(PAI), D-dimer for fibrinolytic system. APA increased significantly in Legg-Clave-Perthes patients(p=0.016) as compared with control group, while Protein C(p=0.040) and Protein S(P=0.0001) decreased significantly in Legg-Clave- Perthes disease. AT- III increased in Legg-Clave-Perthes disease(p=0.0000). In contrast, there were no statistically significant differences in PAI, tPA, D-dimer between the Legg-Clave-Perthes disease and control group. There were no differences in all parameters between the avascular stage and reossification stage in patients with Legg-Clave-Perthes disease, Suggestive of possible inherent effect in coagulation system(hypercoagulable states) which does not change with time. Based on the above findings authors presumed that hypercoagulable state may contribute to the development of Legg-Calve-Perthes disease. However, to elucidate the etiology of Legg-Calve-Perthes disease, further extensive investigation should be followed, which include the familial tendency of hypercoagulable state, relationship with other multifactorial causes such as alcohol and steroids, and confirmation of intravascular thrombosis or decreased blood perfusion in the femoral head. Also, the significance of abnormally elevated AT-III on the disease should be answered.

Purpose: The risk of suicide is approximately two times higher in patients with breast cancer compared to the general population. Suicide risk factors are widely investigated but research on the protective factors is lacking. We investigated whether each subscale of grit, consistency of interest, and perseverance of effort, could serve as a protective factor against suicidality. Materials and Methods: Participants were recruited at the Stress Clinic for Cancer Patients, a psycho-oncology clinic at Asan Medical Center from May 2019 to March 2021. A total of 140 female patients with breast cancer completed self-administered questionnaires including Grit scale, Distress thermometer, and Mini International Neuropsychiatric Interview (MINI) suicidality module. We used PROCESS macro for analyzing the mediation model to identify the protective factors for suicidality. Results: Our findings showed that perseverance of effort showed statistically non-significant associations with psychological distress (p=0.403) and suicidality (p=0.945), however, consistency of interest decreased suicidality through psychological distress (β=–0.015; 95% confidence interval, –0.035 to –0.002). Conclusion The result shows that consistency of interest can be a protective factor against suicidality by reducing psychological distress.
