Prognostic significance of pathological and biological factors in hepatocellular carcinoma 总被引:3,自引:0,他引:3

Prognostic factors in hepatocellular carcinoma (HCC) conventionally consist of staging with the tumour node metastasis system and grading by tumour cellular differentiation. There are also other factors useful in prognostication but most of them are clinical. With new discoveries in the pathobiology of cancers and introduction of new medical technology, pathological and biological factors of HCC in relation to prognosis have been studied quite extensively. Morphological features of the tumour, both gross and histological, have been found to be significantly related to tumour recurrence and patient survival. Recently, applications of new antibodies and techniques have enabled studies on cellular proliferation using different antibodies such as those for proliferating cell nuclear antigen and Ki-67 protein. These studies on cellular proliferation, as well as assessment of argyrophilic nucleolar organizing regions, have been shown to provide good prognostic significance. Flow cytometric studies on DNA ploidy and studies on expression of genes including the p53 gene, hormone receptors and others show less unanimous results in their prognostic significance. The influence of gender on survival is also reviewed. In conclusion, pathological and biological factors are useful and help to guide clinicians in the management of patients and in assessment of long-term prognosis. 相似文献

Soluble CD23 (sCD23) was proposed as a marker of disease activity and as an important prognostic parameter in B‐cell chronic lymphocytic leukemia (B‐CLL). In this study, prognostic significance of sCD23 in B‐CLL was examined according to its temporal relationship with the known clinical parameters of the disease, CD38 and ZAP‐70. Serum sCD23 levels of 36 B‐CLL patients, followed up in our clinic between 1999 and 2005, and 15 healthy subjects were measured with enzyme‐linked immunosorbent assay. The mean serum sCD23 level of the B‐CLL patients (210.72 ± 193.67 and 6–600 U/ml) was significantly higher than the control group (18.20 ± 14.30 and 6–50 U/ml). Seventy‐eight percent of the B‐CLL patients with lymphocyte doubling time (LDT) <12 months and 24% of patients with LDT >12 months had high sCD23 levels (P = 0.008). Meanwhile, 81% of the patients with diffuse bone marrow infiltration and 33% of patients with nondiffuse infiltration had high levels of serum sCD23 (P = 0.029). A significant difference was found between B‐CLL patients with Binet stages A and C (P = 0.009). Peripheral blood flow cytometry of the patients revealed a significant CD38 expression in patients with high serum sCD23 levels (P = 0.002). Similarly, an increased bone marrow zeta‐chain associated protein kinase‐70 (ZAP‐70) expression was seen in patients with high serum sCD23 levels (P = 0.009, correlation co‐efficient was 0.714). Cumulative and the progression free survivals of the patients with low serum sCD23 levels were 60.1 ± 5.7 months [95% confidence interval (CI); 49.0–71.2] and 51.1 ± 6.6 months (95% CI; 38.0–64.1), respectively. However, they were 43.8 ± 6.5 months (95% CI; 31.0–56.6) and 26.5 ± 6.4 months (95% CI; 14.0–39.1) in patients with high levels. Serum sCD23 is increased in B‐CLL patients and can be used in the clinical follow‐up of the disease in prediction of the tumor mass and prognosis. 相似文献

BACKGROUND: The aetiology of pityriasis alba (PA), a common dermatosis in childhood, is still controversial. The objective of this study was to assess the possible aetiopathogenic factors of this disease in infants. METHODS: Forty-four patients with PA and 31 healthy children were examined and compared. Personal hygiene habits, sun exposure, presence of Staphylococcus aureus in nasal fossae and presence of major or minor signs of atopy were assessed during anamnesis and physical examination. Susceptibility to ultraviolet (UV) B radiation was measured by the onset of a contact hypersensitivity reaction to diphenylcyclopropenone in individuals sensitized in previously irradiated areas. RESULTS: The prevalence of PA was higher in individuals with darker skin, in high phototype categories, as well as in males. The number of daily baths and sun exposure between 10.00 h and 15.00 h were significantly higher in the PA group when compared with controls (P = 0.03 and P = 0.0015, respectively). The presence of atopy signs was more common in pityriasis patients (P = 0.002). Susceptibility to UVB radiation was 29.6% in the PA group vs. 29.0% in the control group; nevertheless, important differences were found after stratification in order to control possible confounding factors. The presence of S. aureus in the nostrils was equal in both groups. CONCLUSIONS: Our results confirm that PA, in our population, is more prevalent in males and in individuals in higher phototype categories. In those with inadequate personal hygiene and sun exposure habits the disease is more accentuated, demonstrating that the xerosis presenting in individuals with atopic diathesis is an important element in the development of the disease. S. aureus is not an important aetiopathogenic factor in PA. Susceptibility to UVB becomes important when related to the patient's phototype. 相似文献

Rheography and echocardiography were used to study central and intracardiac hemodynamic parameters in 196 patients with Functional Classes I-II from the screening of the main antianginal drugs during an acute pharmacological test under bicycle ergometric monitoring. It was established that the hemodynamic type of circulation and left ventricular end-diastolic and end-systolic volumes may be used as criteria for the differential choice of antianginal agents. The values of these parameters are given for sustac, propranolol, verapamil, nifedipine and sustac plus propranolol. 相似文献
