  • Purpose: Various postoperative adjuvant chemotherapy regimens have been proposed for the patients with advanced gastric cancer. The majority of clinical trials have shown no significant difference in the survival benefit. The aim of this study was to compare the survival rates of postoperative adjuvant chemotherapies used in stage III gastric cancer patients who received curative gastrectomy. Materials and Methods: Between 1990 and 1999, a survival analysis was performed in 260 patients who received curative gastric resection and postoperative adjuvant chemotherapy. The patients were divided into four groups according to the chemotherapeutic regimens received. The groups were: the F group: furtulon alone, FM group: furtulon and mitomycin, FAM group: 5-FU, adriamycin and mitomycin, FLEP group: 5-FU, leucovorin, etoposide and cisplatin. The survival rates were analyzed using the Kaplan-Meier method and the Cox proportional hazards model. Results: There were no differences among the groups of patients with regard to tumor characteristics except for lymph node metastasis and the ratio of metastasis to lymph nodes. In the FLEP group, the ratio of metastasis to lymph nodes was higher than in the other groups. The five and ten year survival rates of F, FM, FAM and FLEP were 51.9%, 28.9%, 59.5%, 49.8%, 66.1%, 57.4% and 30.0%, 27.5%, respectively. The univariate analysis showed that age, Borrmann type, lymph node metastasis, ratio of metastasis to lymph nodes, postoperative adjuvant chemotherapy and recurrence were significant factors for survival. For the multivariate analysis, recurrence, age, Borrmann type, ratio of lymph node metastasis and lymph node dissection were independent prognostic factors; however, the postoperative adjuvant chemotherapy was not an independent prognostic factor. Conclusion: The FAM regimen was the most beneficial postoperative adjuvant chemotherapy for improved survival rates; the FM regimen was the second and the FLEP regimen was the last. In order to determine the effectiveness of postoperative adjuvant chemotherapy in stage III gastric cancer, well designed prospective studies including a surgery only group will be needed.

  • Objectives: Many studies have examined histopathological factors and various prognostic scores related to inflammation to predict outcomes. Here, we examined the prognostic value of the C-reactive protein/albumin (CRP/alb) ratio in oral squamous cell carcinoma (OSCC). Materials and Methods: This retrospective study included 40 patients with OSCC. Using univariate and multivariate analyses, we focused on the correlation of the CRP/alb ratio with clinicopathological characteristics and with overall survival. We then compared five inflammation-based prognostic scores, CRP/alb ratio, modified Glasgow Prognostic Score (mGPS), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and prognostic nutritional index (PNI), based on receiver operating characteristic (ROC) curves. Results: The optimal cut-off value for the CRP/alb ratio was 0.085. The group with a high CRP/alb ratio had a high TNM clinical stage (P=0.002) and larger primary tumors (P=0.029), with statistically significant differences in lymph node metastasis and distant metastasis. In addition, when the CRP/alb ratio was high, multivariate analysis showed a lower survival rate (P=0.002; hazard ratio=6.078), and the ROC curve showed more outstanding discriminatory ability regarding overall survival compared to other inflammation-based prognostic scores. Conclusion: The CRP/alb ratio can be an independent prognostic factor when predicting prognosis in OSCC and has good prognostic ability.

  • Background: Breast cancer is the second leading cause of cancer death for women in the United States. Differences in survival of breast cancer have been noted among racial and ethnic groups, but the reasons for these disparities remain unclear. This study presents the characteristics and the survival curve of two racial and ethnic groups and evaluates the effects of race on survival times by measuring the lifetime data-based half-normal model. Materials and Methods: The distributions among racial and ethnic groups are compared using female breast cancer patients from nine states in the country all taken from the National Cancer Institute's Surveillance, Epidemiology, and End Results cancer registry. The main end points observed are: age at diagnosis, survival time in months, and marital status. The right skewed half-normal statistical probability model is used to show the differences in the survival times between black Hispanic (BH) and black non-Hispanic (BNH) female breast cancer patients. The Kaplan-Meier and Cox proportional hazard ratio are used to estimate and compare the relative risk of death in two minority groups, BH and BNH. Results: A probability random sample method was used to select representative samples from BNH and BH female breast cancer patients, who were diagnosed during the years of 1973-2009 in the United States. The sample contained 1,000 BNH and 298 BH female breast cancer patients. The median age at diagnosis was 57.75 years among BNH and 54.11 years among BH. The results of the half-normal model showed that the survival times formed positive skewed models with higher variability in BNH compared with BH. The Kaplan-Meir estimate was used to plot the survival curves for cancer patients; this test was positively skewed. The Kaplan-Meier and Cox proportional hazard ratio for survival analysis showed that BNH had a significantly longer survival time as compared to BH which is consistent with the results of the half-normal model. Conclusions: The findings with the proposed model strategy will assist in the healthcare field to measure future outcomes for BH and BNH, given their past history and conditions. These findings may provide an enhanced and improved outlook for the diagnosis and treatment of breast cancer patients in the United States.

  • Background: Colorectal cancers(CRC) are the third most common cancer in the western world, with surgery preferred for management of non-metastatic disease and post surgical treatment usually arranged according to the TNM staging system. However, there is still prognostic variation between patients who have the same stage. It is increasingly recognized that variations within disease course and clinical outcome in colorectal cancer patients are influenced by not only oncological characteristics of the tumor itself but also host response factors. Recent studies have shown correlation between the inflammatory response and clinical outcomes in various cancers. The neutrophil/lymphocyte ratio (NLR) has been described as a marker for immune response to various stimuli including cancer. Material-Methods: Two hundred eighty-one CRC patients were included in our retrospective analysis, separated into two groups according to a cut-off value for the NLR. Patient data including age, gender, vertical penetration, anatomic location, and differentiation of the tumor, TNM stage, survival rate, and disease-free survival were analyzed for correlations with the NLR. Results: Using ROC curve analysis, we determined a cut-off value of 2.2 for NLR to be best to discriminate between patient survival in the whole group. In univariate analysis, high pretreatment NLR (p=0.001, 95%CI 1.483-4.846), pathologic nodal stage (p<0.001, 95%CI 1.082-3.289) and advanced pathologic TNM stage (p<0.001, 95%CI 1.462-4.213) were predictive of shorter survival. In multivariate analysis, advanced pathologic TNM stage (p=0.001, 95%CI 1.303-26.542) and high pretreatment NLR (p=0.005, 95%CI 1.713-6.378) remained independently associated with poor survival. Conclusions: High pre-treatment NLR is a significant independent predictor of shorter survival in patients with colorectal cancer. This parameter is a simple, easily accessible laboratory value for identifying patients with poorer prognosis.

  • Objective : The association of cancer survival and components of the systemic inflammatory response, combined to form inflammation-based prognostic scores (modified Glasgow Prognostic Score (GPS), Neutrophil Lymphocyte Ratio, Platelet Lymphocyte Ratio) is reviewed in this article. Methods and Results : With extensive research of papers in the PubMed, there is good evidence that preoperative measures of the systemic inflammatory response predict cancer survival, independent of tumor stage, in primary operable cancer. GPS also shows its prognostic value as a predictor of survival, independent of tumor stage, performance status and treatment in a variety of advanced cancer. GPS is associated with chemotherapy related toxicities as well as response to treatment and C-reactive protein shows its clinical value as a monitor of chemotherapy response. The systemic inflammatory response is closely related to cachexia and may be suitable measure for the clinical definition of cancer cachexia. Conclusion : Anticipated survival using the inflammation-based prognostic score is a major factor to be taken into consideration when deciding whether active intervention including surgery and chemotherapy or palliation therapy including acupuncture and herb medication is appropriate.

  • In biofloc culture for olive flounder, Paralichthys olivaceus, the possibility of antibiotics treatment was investigated against edwardsiellosis. After inducing edwardsiellosis by immersion in Edwardsiella tarda 1.2 × 105/mL suspension, the survival trends on various biofloc water management and some physiological changes were observed. For biofloc water management, six types of water treatments were carried out, which were no exchange without antibiotics as negative control, the exchange to stored biofloc water, the exchange to stored biofloc water with 20% flow-through, the exchange to fresh biofloc water, half fresh biofloc water and half sea water, and the complete flow-through. There was no significant physicochemical change on water qualities in any type. The exchange to fresh biofloc water was shown the highest survival ratio as 72.3%, and in case of stored biofloc water with 20% flow-through, the survival ratio was also significantly high as 62%. Plasma glucose, cholesterol, total protein, calcium, and magnesium were analyzed as physiological index. Mostly, there was no significant change, but plasma cholesterol showed an initial decrease in low survival group, and an initial increase with high survival group. Consequently, antibiotic treatment against a bacterial disease during biofloc culture is possible as long as the biofloc water management follow along properly.

  • 목적: 본 연구의 목적은 단일 술자가 시행한 슬관절 부분 치환술의 장기 임상적, 방사선적 결과 및 생존율을 분석하는 것이다. 또한 치환물의 생존에 영향을 미치는 인자를 분석하고 그에 따른 생존 곡선을 비교하는 것이다. 대상 및 방법: 1982년 12월부터 1996년 1월까지 시행된 슬관절 부분 치환술 99예를 대상으로 하였다. Modular II 10예, Microloc 44예, Allegretto 45예였다. 평균 추시기간은 16.5년이었다. 임상적 평가로 술 전, 술 후 1년, 최종 추시 hospital for special surgery(HSS) 점수와 관절운동범위를 조사하였다. 방사선적 평가로 술 전, 술 후 2주, 최종 추시 대퇴 경골각을 조사하였다. Kaplan-Meier 생존 분석을 이용하여 생존율을 분석하였다. Cox 비례위험모형을 이용하여 나이, 성별, 체질량 지수, 술 전 진단, 치환물의 종류 중 생존에 영향을 미치는 요인을 조사하였다. 생존에 영향을 미치는 인자에 따라 군을 나누어 생존 곡선을 비교하였다. 결과: 전체 HSS 점수는 평균 술 전 57.7점, 술 후 1년 92.7점, 최종 추시 79.1점이었다(p<0.001). 관절운동범위는 평균 술 전 134.3도, 술 후 1년 138.4도, 최종 추시 129.3도였다(p<0.001). 전체 대퇴 경골각은 평균 술 전 내반 0.8도, 술 후 2주 외반 4.1도, 최종 추시 외반 3.0도였다(p=0.003). 전체 생존율은 5년 91.8%, 10년 82.9%, 15년 71.0%, 20년 67.0%였다. 부분 치환술의 생존에 영향을 미치는 요인은 환자의 나이와 치환물의 종류였다. 나이가 높을수록 실패 위험이 낮았으며(hazard ratio=0.933), Microloc 사용 시 Modular II와 Allegretto에 비해 위험률이 높았다(hazard ratio=0.202, 0.430, respectively) 60세 미만군의 생존 곡선이 60세 이상 군에 비해 의미 있게 낮았다(p=0.003). Microloc 사용군의 생존 곡선이 Modular II와 Allegretto 사용군에 비해 낮았다(p=0.025). 결론: 고정형 치환물을 사용한 슬관절 부분 치환술의 장기 임상적, 방사선적 결과 및 생존율은 만족스러웠다. 부분 치환물의 장기 생존을 위해 적절한 환자와 치환물의 선택이 중요할 것이다.

  • 목적: Palliative Performance Scale (PPS)는 진행성 암환자에서 널리 사용되는 예후도구이다. PPS 측정이 생존에 대한 예측을 의미하지만, 연속적인 PPS 측정에 대한 유용성은 추가적인 연구가 필요하다. 본 연구에서는 완화 병동에 입원한 진행성 암환자를 대상으로 PPS score의 변화와 생존간의 연관성에 대해 진행한 연구이다. 방법: 2010년 1월부터 2012년 12월까지 서울성모병원 완화의학과에 입원한 환자 606에 대한 의무기록을 통하여 입원 당일의 PPS score와 입원 3일째의 PPS score 그리고, 두 score의 차이를 측정하여 점수의 변화와 생존간의 관련성을 분석하였다. 결과: PPS score의 변화와 생존과는 통계적으로 유의한 관련이 있었다. PPS score의 변화가 30% 이하인 군과 비교하였을 때, 30% 초과된 군에서 hazard ratio가 2.66(95% CI 2.19~3.22)로 확인되었다. 입원 3일째 PPS score가 30% 이하인 경우 독립적으로 생존에 대한 예측이 가능하였으며, PPS score 30% 초과된 군과 비교했을 때 hazard ratio는 1.67 (95% CI 1.38~2.02)로 확인되었다. 입원 당시의 PPS score는 생존과 독립적인 관련성은 없었다. 결론: 후향적으로 의무기록 분석을 통해 이루어진 본 연구에서 30% 이상의 PPS score 변화는 입원중인 말기 암환자의 생존과의 관련이 확인되었다. 입원 당시의 PPS score는 생존을 예측하지 못했다. PPS score의 변화는 말기암환자에서 단일 PPS score 측정보다 더 민감한 지표일 수 있다. 차후 더 많은 환자들에서 이에 대한 다기관, 전향적 연구가 필요하다.
