原发性肝癌介入治疗中影响生存因素及其临床意义

探讨原发性肝癌累积生存率与肿瘤形态、门脉癌栓及治疗方法、次数和间隔时间的关系，以提出恰当的治疗方案。６２１例资料完整的肝癌病人行２次以上介入治疗，分析其生存率与肿瘤形态、门脉癌栓及治疗方法、次数和间隔时间的关系。结果：（１）单结节生存率最高，弥漫型最差。（２）门脉内没有癌栓的病人生存率显著高于门脉内有癌栓的，但癌栓的部位与生存率关系不大。（３）介入治疗以药物灌注加碘油及明胶海绵栓塞（ＬｐＧｓＴＡＣＥ）效果最佳。（４）治疗次数和间隔时间要依具体情况而定，关键是ＴＡＣＥ的质量。肿瘤形态、门脉癌栓及治疗方法、次数和间隔时间对原发性肝癌的累积生存率影响很大，对这类病人应行“个案化治疗”

Prognostic value of the colposcopic tumor size in stage IB squamous cervical cancer

BACKGROUND AND OBJECTIVES: To determine the prognostic significance of the colposcopic tumor size in the management of cervical cancer. METHODS: Clinicopathological analysis was performed in 751 consecutive patients with stage IB squamous cervical cancer who were surgically treated in a single institute. The colposcopic tumor size was measured postoperatively on surgical specimens. Univariate and multivariate analyses were performed to determine the prognostic significance of various pathological factors. RESULTS: Among the pathological factors examined, lymph node metastasis, parametrial extension, deep stromal invasion, vessel permeation, endometrial extension, and colposcopic tumor size were found to be prognostic factors in univariate analysis, whereas multivariate analysis has confirmed that only three factors, i.e., lymph node metastasis, parametrial involvement, and colposcopic tumor size were independently associated with the disease-free interval. CONCLUSIONS: These results indicate that the colposcopic tumor size is an independent prognostic factor in squamous cervical cancer and can be used as an indicator of treatment options.

Prognostic factors analysis for stage I rectal cancer

Objective: To explore the death-related factors of stage I rectal cancer patients. Methods: 89 cases of stage I rectal cancer patients between 1985 and 2000 were retrospectively studied for prognostic factors. Factors including age, gender, tumor size, circumferential occupation, gross type, pathological type, depth of tumor invasion, surgical procedure, adjuvant chemotherapy and postoperative complication were chosen for cox multivariate analysis (forward procedure) using Spss software (10.0 version). Results: multivariate analysis demonstrated that muscular invasion was an independent negative prognostic factor for stage I rectal cancer patients (P=0.003). Conclusion: Muscular invasion is a negative prognostic factor for stage I rectal cancer patients. Biography: WU Ai-wen(1974–), doctoral candidate, resident doctor, majors in surgical oncology.     

Prognostic factors in inflammatory breast cancer. Univariate and multivariate analysis

Between 1958 and 1985, 107 patients with nonmetastatic inflammatory breast cancer (IBC) received radiotherapy as all or part of initial treatment at the Mallinckrodt Institute of Radiology. For this review, the diagnosis of IBC was made on the basis of either clinical or histopathologic criteria. Fifteen factors of potential prognostic significance were evaluated, by both univariate and multivariate analysis. For relapse-free survival, univariate analysis suggested prognostic value for initial tumor size, discrete versus diffuse tumor mass, adjuvant chemotherapy, and mastectomy. In the multivariate analysis, the independent prognostic factors, in order of significance, were mastectomy, diffuse versus discrete tumor mass, and race (marginal). For survival, univariate analysis suggested prognostic value for initial tumor size, diffuse versus discrete tumor mass, nodal stage, year of treatment, adjuvant chemotherapy, and mastectomy. In the multivariate analysis, the prognostic factors in order of significance were mastectomy and chemotherapy (marginal). The diagnostic selection group showed no prognostic value, suggesting that either clinical or histopathologic criteria justify the diagnosis of IBC. Our results appear to support a role for surgery as part of the combined modality approach to this disease.     

Prognostic factors affecting survival in male breast cancer

Male breast cancer is an uncommon disease and most of the data concerning its treatment and prognostic factors have been obtained from studies spanning a long period of time during which the main concepts of treatment in breast cancer have changed. In the current study, patients affected with male breast cancer treated in the last decade with a multidisciplinary approach were reported from a single Institution. Fifty-five patients with male breast cancer treated between 1990 and 1998 were included in this study. The median follow-up period was 36 months. Five-year disease-free and overall survival were 44.5% and 72.9%, respectively. Patients' age, tumor size, axillary status, tumor type and treatment modalities such as surgery, chemotherapy, radiotherapy, and hormonotherapy were evaluated as possible prognostic factors affecting the disease-free and overall survival periods. In univariate analysis, tumor size, axillary status and extent of surgery were found to be affecting overall survival significantly whereas axillary status, tumor type, extent of surgery and chemotherapy affected disease-free survival. In multivariate analysis, axillary status, extent of surgery and tumor type were found as independent prognostic factors for overall survival and radiotherapy was added to these factors for disease-free survival. In conclusion, the approach to male breast cancer patients should be similar to that for female patients. Modified radical mastectomy should be the gold standard followed by combined adjuvant therapy individualized for patients due to axillary status, tumor size and type.

Prognostic Factors of Adrenocortical Carcinoma: An Analysis of the Surveillance Epidemiology and End Results (SEER) Database

Objective: To define the prognostic factors associated with overall survival (OS) and cancer-specific survival (CSS) for adrenocortical carcinoma (ACC). Patients and Methods: We used the Surveillance, Epidemiology and End Results (SEER) database (1973-2014) to identify ACC patients. Correlated variables, including age, sex, race, tumor laterality, marital status at diagnosis, treatment of primary site, lymph node dissection, radiation therapy, chemotherapy, tumor size and tumor stage, were extracted. Univariate and multivariate Cox regression were used to define the prognostic factors. Harrell’s concordance index (C index) was calculated to evaluate the discrimination ability for the prognostic predictive models. Results: There were 749 ACC patients identified from the database. The overall median survival time was 22 (95%CI, 18-25) months. In multivariate analysis, age, treatment, chemotherapy and tumor stage were independent risk factors for both overall and cancer-specific survival. Tumor stage had a dominant effect on the cancer prognosis. Additionally, the ENSAT stage had better discrimination than the AJCC stage group in different predictive models. Conclusion: Our study shows that age, treatment of primary site, chemotherapy and tumor stage were prognostic factors for overall and cancer-specific mortality in ACC patients. Among these factors, tumor stage had a dominant effect. The ENSAT stage was more discriminative than the 7th AJCC stage group. Further multi-center prospective validation is still needed to confirm these outcomes.     

Prognostic value of lymphovascular space invasion determined with hematoxylin-eosin staining in early stage cervical carcinoma: results of a multivariate analysis.

BACKGROUND: Our aim was to study the prognostic value of the presence of lymphovascular space invasion (LVSI) in patients with stage IB and II cervical carcinoma treated by initial surgery. PATIENTS AND METHODS: A retrospective analysis was performed on 193 patients who underwent, between 1985 and 1998, an initial radical hysterectomy with pelvic (+/- para-aortic) lymphadenectomy using midline laparotomy for stage IB (180 patients) or II (13 patients) cervical carcinoma. Postoperative therapy was delivered according to prognostic factors. RESULTS: The rate of LVSI correlated significantly with tumor stage, nodal status and the location of positive nodes. Using univariate analysis, tumor size (<4 or >/= 4 cm), LVS status and nodal status were prognostic factors. At multivariate analysis, two prognostic factors were identified: LVS status and nodal status. In a subgroup of 89 patients with a small tumor (相似文献
