The Sokal and Hasford scores were developed in the chemotherapy and interferon era and are widely used as prognostic indicators in patients with chronic myeloid leukemia (CML). Recently, a new European Treatment and Outcome Study (EUTOS) scoring system was developed. We performed a multicenter retrospective study to validate the effectiveness of each of the three scoring systems. The study cohort included 145 patients diagnosed with CML in chronic phase who were treated with imatinib. In the EUTOS low‐ and high‐risk groups, the cumulative incidence of complete cytogenetic response (CCyR) at 18 months was 86.9% and 87.5% (= 0.797) and the 5‐year overall survival rate was 92.6% and 93.3% (= 0.871), respectively. The cumulative incidence of CCyR at 12 months, 5‐year event‐free survival and 5‐year progression‐free survival were not predicted using the EUTOS scoring system. However, there were significant differences in both the Sokal score and Hasford score risk groups. In our retrospective validation study, the EUTOS score did not predict the prognosis of patients with CML in chronic phase treated with imatinib.  相似文献

Introduction: The objective of this paper is to identify the prognostic risk factors of secondary adult hemophagocytic syndrome (HLH) in hospitalized patients and establish a simple and convenient prognostic scoring system. Method:We reviewed 162 adult patients secondary with HLH treated in Zhejiang Cancer Hospital and the First Affiliated Hospital of Medical College of Zhejiang University from January 2014 to December 2018 were enrolled to form the test group; from January 2019 to February 2021, 162 adult patients in the hospitals constituted the validation group. The HLH prognosis scoring system was constructed according to the risk factors, and the patients were divided into three risk groups: low risk, medium risk, and high risk. The scoring system was verified by Kaplan–Meier method and log rank test survival analysis. The discrimination ability was evaluated according to the receiver operating characteristic (ROC) curve. Results: Univariate and multivariate analysis showed that the independent risk factors for the prognosis of HLH were male sex, activated partial prothrombin time (APTT) greater than 36 s, lactate dehydrogenase (LDH) greater than 1000 U/L, and C-reactive protein (CRP) greater than 100 mg/L. The area under the ROC curve was 0.754 (95% Cl: 0.678–0.829). The patients were divided into a low-risk group (0–1), a medium-risk group (2–4), and a high-risk group (5–6). The 5-year overall survival (OS) rate were 87.5%, 41.8% and 12.8%, respectively (p < 0.001). The area under ROC curve was 0.736 (95% Cl: 0.660–0.813) in the validation group, and the 2-year OS of patients in low-risk, medium-risk and high-risk groups were 88.0%, 45.1% and 16.7%, respectively (p < 0.001). Conclusion:The new prognostic scoring system can accurately predict the prognosis of secondary adult HLH and can further provide basis for the accurate treatment of secondary adult HLH.  相似文献

BACKGROUND: Up to 5% of patients with chronic myelogenous leukemia (CML) do not have the Philadelphia (Ph) translocation t(9;22)(q34;q11) or a bcr/abl molecular rearrangement. Although the diagnostic criteria of this entity are still under debate, there is general agreement that patients with Ph negative, bcr/abl negative CML have a severe clinical course that is not affected significantly by current treatment options. METHODS: A population of 76 patients with bcr/abl negative CML who had received minimal or no previous therapy was characterized carefully with the intent of investigating clinical and hematologic variables and their association with survival by univariate, correlation, and multivariate analyses. A group of 73 patients with Ph negative CML who were not tested for the bcr/abl rearrangement (bcr/abl unknown) was analyzed separately and used for extension of the analysis. RESULTS: In the bcr/abl negative patient population, the median overall survival was 24 months. At the time of the analysis, 38 patients (50%) had died, and blastic transformation preceded death in 31%. Chromosomal abnormalities were found in 30% of the 76 patients, with trisomy 8 the most common abnormality. Complex chromosomal abnormalities were rare, and monosomy 7 was not observed. Survival was not affected significantly by treatment. Multivariate analysis identified older age (> 65 years), anemia (hemoglobin < 10 g/dL), and severe leukocytosis (white blood cells > 50 x 10(9)/L) as variables with independent prognostic significance for poor survival. A prognostic scoring system stratified patients into a low-risk group (53%) and a high-risk group (47%), with median survivals of 38 months and 9 months, respectively. CONCLUSIONS: Bcr/abl negative CML is a distinct clinical entity associated with very poor prognosis. Two risk categories are identifiable using a simple scoring system based on age, hemoglobin level, and leukocyte number.  相似文献

BACKGROUND: The effect on prognosis of adding imatinib mesylate to the treatment of patients with Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML) has not been explored fully. The objective of the current study was to evaluate the benefit of adding imatinib to the treatment sequence of patients with early chronic phase Ph-positive CML who received interferon alpha (IFN)-based regimens as frontline therapy. METHODS: A total of 201 patients with early chronic phase Ph-positive CML who were treated on our 3 recent frontline IFN-based programs and were impacted early by the availability of sequential therapy with imatinib were analyzed. Their outcome was compared with that of a historical control group of 293 patients treated from 1982 until 1990 who were treated with IFN programs for early chronic phase CML and who did not have the opportunity of early access to imatinib (because it was not available during that period). Multivariate analysis was used to evaluate the independent effect of imatinib therapy on survival. RESULTS: Of 201 patients who were treated, 159 patients (79%) had their regimen changed sequentially to imatinib after a median duration of 14 months of IFN therapy. Of 139 patients who continued evaluation at our institution, 101 patients (73%; 64% of the total group) achieved a complete cytogenetic response, and 20 of 80 patients analyzed (25%; 10% of the total group) had no disease according to molecular studies (quantitative polymerase chain reaction studies). The estimated 5-year survival rate for the total study group of 201 patients was 86%. Survival of this group was significantly superior to the historic control group of IFN-treated patients who did not have the benefit of imatinib (P = 0.03). The trend also was observed within defined CML risk groups. Imatinib therapy was confirmed as an independent, significant, favorable prognostic factor for survival by multivariate analysis, after accounting for the independent prognostic effect of pretreatment prognostic factors (P = 0.005). CONCLUSIONS: The current analysis is the first to indicate the independent, favorable effect of imatinib on the survival of patients with Ph-positive CML.  相似文献

A staging system for hepatocellular carcinoma was reported from Italy (CLIP). In this study, we evaluate the CLIP scoring system and establish a new scoring system for predicting the prognosis of patients with hepatocellular carcinoma. Patients (n=141) who were diagnosed and who underwent initial treatment at our single institution were recruited retrospectively into this study. We evaluated markers for prognosis, using a stratified Cox proportional hazard regression model and Kaplan-Meier survival analysis. CLIP score differentiated patients with different survival experiences by Kaplan-Meier estimated survival analysis. However, with respect the CLIP score, more than two thirds of patients were included in the early stage (CLIP 0-1), and the group with better prognosis than the survival rate of all patients was the only one with CLIP 0. Multivariate analysis revealed that des-gamma-carboxy prothrombin (DCP) >/=100 mAU/ml (relative risk, 2.06; P=0.0218) was statistically significant as a predictor of poor survival. A new prognostic scoring system included DCP classified patients to 6 well-balanced groups (score 0-5). The new prognostic scoring system 0 group (14.9% of the cohort) and the CLIP score 0 group (34.0% of the cohort) had a median survival of 66.9 and 61.6 months. The new prognostic scoring system performs better for prediction of survival than either the CLIP score or the Child-Pugh stage. In conclusion, the described scoring system provides more accurate prognostic information than the CLIP scoring system. It may help physicians decide more appropriate clinical and therapeutic management.  相似文献

Survival and prognostic factors of skin melanoma patients were studied using a regression analysis of relative survival rates based on nationwide cancer registry data. The material consisted of 4980 cases of melanoma of the skin diagnosed in Finland in 1953 to 1981 and reported to the Finnish Cancer Registry. In the last diagnostic period, 1974 to 1982, the 5-year relative survival rate for male patients was 61.1% and that for female patients 76.6%. The analysis included variables sex, age, stage, year of diagnosis, follow-up year, and site of the tumor. All of them were needed to explain the differences in survival. The patients had the greatest relative risk of dying from skin melanoma during the second year from diagnosis. However, the difference in death risk due to melanoma by stage was most remarkable during the first follow-up year: the risk of patients with nonlocalized disease was over 12 times that of others. The male-female ratio in the risk of dying from skin melanoma was (to a marked extent) attributable to differences in the distributions of stage and site of the tumor. In all site groups males did worse than females but risk ratio varied from 1.15 (trunk) to 1.89 (limbs). The effect of some important prognostic factors on survival could be quantified with ample material and with a method taking into account the competing causes of death. The results suggest a difference either in biological behavior of skin melanoma or in a patient's delay between males and females.  相似文献

Three hundred and twenty-seven patients with endometrial carcinoma stage I-II were all followed for at least 5 years. The estradiol receptor concentrations were measured in 298 tumors. In 272 cases the progesterone receptor concentrations were measured as well. Both receptors were significant prognostic factors measured as 5 year survival rate. In a Cox regression test stage, degree of differentiation, myometrial invasion and age remained as independent significant factors. Progesterone receptor concentrations were almost significant in a two-sided test including all degrees of differentiation but were significant (p = 0.04) when only poorly differentiated tumors were included. Thus PgR concentrations were used only on poorly differentiated tumors. The patients could be divided into a high risk group (deep myometrial invasion), an intermediate risk group (poorly differentiated carcinomas without deep myometrial invasion but with a low progesterone receptor concentration) and a low risk group (the remaining) with 5 year survival rated of 61%, 80% and 96% respectively.  相似文献

Objective:Acute myeloid leukemia (AML) is primarily a malignant disorder affecting the elderly. We aimed to compare the outcomes of different treatment patterns in elderly AML patients and to propose a prognostic scoring system that could predict survival and aid therapeutic decisions.Methods:Patients aged ≥ 60 years who had been diagnosed with AML at 7 hospitals in China were enrolled (n = 228). Treatment patterns included standard chemotherapy, low intensity therapy, and best supportive care (BSC).Results:The early mortality rates were 31%, 6.8%, and 6.3% for the BSC, low intensity therapy, and standard chemotherapy groups, respectively. The complete remission rate of the standard chemotherapy group was higher than that of the low intensity therapy group. The median overall survival (OS) was 561 days and 222 days for the standard chemotherapy and low intensity therapy groups, respectively, and were both longer than that of the BSC group (86 days). Based on multivariate analyses, we defined a prognostic scoring system that enabled classification of patients into 3 risk groups, in an attempt to predict the OS of patients receiving chemotherapies and low intensity therapies. Low and intermediate risk patients benefited more from standard chemotherapies than from low intensity therapies. However, the median OS was comparable between standard chemotherapies and low intensity therapies in high risk patients.Conclusions:Our prognostic scoring system could predict survival and help select appropriate therapies for elderly AML patients. Standard chemotherapy is important for elderly AML patients, particularly for those categorized into low and intermediate risk groups.  相似文献

Clinical heterogenicity exists within an acute myeloid leukemia (AML) patient group with the same cytogenetic risk. Multi-drug resistance (MDR) is also regarded as one of the potential prognostic factors for AML. Accordingly, the prognostic scoring model can be generated based on both consideration of cytogenetic risk and the MDR status for AML. The CR rate, event-free (EFS) and overall survival (OS) were analysed according to cytogenetic risk, MDR status and clinical factors. Prognostic score was calculated by the sum of MDR status (0 for negative, 1 for positive) and dichotomized scoring for cytogenetic risk (0 for favorable/intermediate and 1 for unfavorable cytogenetics). MDR expression was noted in 36.6% of the patients and associated with a lower CR rate (p = 0.037). MDR, cytogenetics and the use of SCT were identified as independent prognostic factors for EFS and OS. The CR rate of the group scored with 0, 1 and 2 was 81.4, 66.7, and 44.4%, respectively (p = 0.050). The prognostic scoring model depicted a discriminating role in terms of EFS (p < 0.0001) and OS (p = 0.0001). The prognostic scoring model based on cytogenetic risk and MDR provided an improved method for evaluating the prognosis in AML and helped to stratify the risk of patients with the same cytogenetic risk.  相似文献
