[Expression of MMP-2 and E-CD in salivary mucoepidermoid carcinoma and its correlation with infiltration, metastasis and prognosis].

OBJECTIVE: To study the expressions of matrix metalloproteinase 2 (MMP2) and E-cadherin (E-CD) in salivary mucoepidermoid carcinoma, and their relationship with clinical stages, pathological grading, lymph node metastasis and prognosis. METHODS: Surgical specimens of salivary mucoepidermiod carcinoma and normal salivary gland tissue were collected. MMP-2 and E-CD were stained immunohistochemically with streptavidin peroxidase method. RESULTS: The expression of MMP-2 was increased and the expression of E-CD was reduced or negative in salivary mucoepidemoid carcinoma compared with those of the normal salivary gland. Expression of MMP-2 and E-CD was closely correlated with lymph node metastasis of the mucoepidermoid carcinoma. MMP-2 was positively correlated with the prognosis of mucoepidermoid carcinoma, and E-CD was negatively correlated to the prognosis of mucoepidermoid carcinoma. CONCLUSION: The expression of MMP-2 and E-CD is closely correlated with the metastasis and prognosis of salivary mucoepidermoid carcinoma.

Down-regulated p16 expression predicts poor prognosis in patients with extrahepatic biliary tract carcinomas.

The prognosis of extrahepatic biliary tract cancer (EBT) patients is generally accepted to be poor. We immunohistochemically evaluated expression of p16, a cyclin-depend kinase inhibitor, in tumor specimens surgically removed from 99 EBT patients. We also examined whether there was any relationship between expression of p16 and biological malignancy of the tumor by comparing its clinicopathological factors. Consequently, we found that there were three types of p16 expression in the tumor cells; diffuse, heterogeneous and negative types, the percentages of which were 19, 41 and 39%, respectively. Heterogeneous and negative types, whose expression of p16 was considered to be down-regulated, showed scirrhous (p=0.022) and infiltrating growth (p=0.002). In addition, we found that the proportion of down-regulated expression of p16 was different, depending on the location of the tumor. We also observed that the down-regulated p16 expression was the highest in a proportion of patients with the extrahepatic bile duct carcinoma. In contrast, the proportion of down-regulated p16 expression was the least among the patients in the region of the ampulla of Vater with better prognosis, and we showed that the prognosis of patients with down-regulated expression of p16 was the poorest in terms of the cancer location where it is limited to the region of ampulla of Vater. These findings suggest that down-regulated p16 expression is evaluated as a factor of poorer prognosis and also that immunohistochemical pattern of p16 expression becomes a marker reflecting the biological malignancy of EBT patients.

Prognosis for patients with pneumonectomy or lesser resections for non-small cell lung cancer based on histologic cell type.

Contrary results have been reported regarding prognosis by histologic cell type in surgical treatment for lung cancer. To evaluate whether histologic cell type has influence on prognosis, we separately analyzed the prognostic outcome of patients who had undergone pneumonectomy (n=119) and lesser resections (n=124) for non-small cell lung cancer (NSCLC) between January, 1985 and March, 1996. The pneumonectomy group included 87 (73%) squamous cell carcinoma (Sq), 25 (21%) adenocarcinoma (Ad) and 7 other types with 10 (8%) patients in postoperative stage I of the disease, 29 (24%) stage II, 74 (62%) stage III and 6 in stage IV. The lesser resection group included 45 (36%) Sq, 63 (51%) Ad and 16 other types with 71 (57%) patients in stage I, 9 (7%) stage II, 32 (26%) stage III and 12 stage IV. In patients with stages I-III, the 5-year survival rate was 42.8% for the Sq group and 41.1% for the Ad group in the case of lesser resections and 37.1% for the Sq group and 0% for the Ad group (p<0.05) in the case of pneumonectomy. The poorer prognosis for patients with Ad in the case of pneumonectomy was suspected to be due to the N factor; the percentage of patients with N0-1 was significantly lower in the Ad group than for the Sq group (28 vs 62%, p<0.005). Histologic cell type can be a prognostic factor for patients undergoing surgical treatments for NSCLC. One possible reason for the contrary results on prognosis by histologic cell type among investigators may be due to the mixed results of pneumonectomy and lesser resections.

[Change of reactive small round cell infiltration in the stroma after pre-operative 8 Gy irradiation using treatment to maxillary sinus carcinoma with Kitasato method and prognosis according to the change].

PURPOSE: In this paper, we report the results of studying the degree of reactive small round cell infiltration in the stroma as a prognostic indicator of maxillary sinus carcinoma treated with the Kitasato method and the effect of preoperative irradiation at 8 Gy on infiltration in the stroma. SUBJECTS: Out of 74 patients who had been treated with this method in the 27 years from 1976 to 2002, the following patients were enrolled in this study: (1) 17 patients from whom tissue specimens could be obtained with biopsies or probe antrotomies before preoperative irradiation, and (2) 40 patients from whom tissue specimens could be obtained after preoperative irradiation including those who survived five years and who died of a specific cause. METHOD: We classified the pattern of distribution of small round cell infiltration in the stroma into three degrees. (1) Stromal infiltration was compared before and after the operation to recognize the prognosis for each patient based on the pattern of distribution of small round cell infiltration in the stroma. (2) The correlation between the degree of stromal infiltration and prognosis was studied statistically. RESULTS: (1) Both the patients with increased stromal infiltration and those postoperatively preserving a preoperative score of 2+ with irradiation at 8 Gy had a good prognosis. (2) The five-year survival rate for patients was significantly higher in those with a score of 2+ for their tissue specimens. CONCLUSION: The Kitasato treatment method is effective and improves the QOL of patients with maxillary sinus carcinoma. The prognosis was good in the patients with increased or preserved stromal infiltration. The low-dose irradiation and chemotherapy used in combination seemed to be biological response modifiers.

Evaluation of plasma cell propidium-iodide and annexin-V indices: their relation to prognosis in multiple myeloma.

In a group of 117 patients with multiple myeloma (MM) examined at the time of diagnosis, i.e. excluding previous chemotherapy, we analysed the levels of propidium-iodide (proliferative) - PC-PI/CD(138) and annexin-V (apoptotic) - PC-AI/CD(138) indices of myeloma plasmocytes using the method of flow-cytometry to determine their relationship to prognosis. It was revealed that patients with high values of PC-PI/CD(138) had substantially worse overall survival than those with low values. Patients with a level of propidium-iodide index > or = 2,8 % exprimed a median survival of 13 months only in comparison with 42 months in patients with levels < 2,8 % (p = 0,0005). In the PC-AI/CD(138) index a reverse trend was registered. Patients with PC-AI/CD(138) > or = 4,0 % had long overall survival (median was not assessable at the time of evaluation), whereas patients with low apoptosis values < 4,0 % had median overall survival 16 months only (p = 0,01). Based on the sequentional graphic analysis of the curves of overall survival was found that the optimal discrimination level sequestering patients with good and poor prognosis was, in the case of PC-PI/CD(138) value 2,8 %, whereas in the case of PC-AI/CD(138) value 4,0 %. Among patients with good prognosis, there were no statistically significant differences in overall survival according to different levels of proliferative and apoptotic index. We conclude that evaluation of the propidium-iodide and annexin-V index using flow-cytometry is a quick, useful, and easily accessible method for the evaluation of plasma cell kinetics and thus prognosis of the disease, multiple myeloma.

Evaluation of the quality of prognosis studies in systematic reviews.

BACKGROUND: To provide valid assessments of answers to prognostic questions, systematic reviews must appraise the quality of the available evidence. However, no standard quality assessment method is currently available. PURPOSE: To appraise how authors assess the quality of individual studies in systematic reviews about prognosis and to propose recommendations for these quality assessments. DATA SOURCES: English-language publications listed in MEDLINE from 1966 to October 2005 and review of cited references. STUDY SELECTION: 163 systematic reviews about prognosis that included assessments of the quality of studies. DATA EXTRACTION: A total of 882 distinct quality items were extracted from the assessments that were reported in the various reviews. Using an iterative process, 2 independent reviewers grouped the items into 25 domains. The authors then specifically identified domains necessary to assess potential biases of studies and evaluated how often those domains had been addressed in each review. DATA SYNTHESIS: Fourteen of the domains addressed 6 sources of bias related to study participation, study attrition, measurement of prognostic factors, measurement of and controlling for confounding variables, measurement of outcomes, and analysis approaches. Reviews assessed a median of 2 of the 6 potential biases; only 2 (1%) included criteria aimed at appraising all potential sources of bias. Few reviews adequately assessed the impact of confounding (12%), although more than half (59%) appraised the methods used to measure the prognostic factors of interest. LIMITATIONS: Reviews may have been missed by the search or misclassified because of incomplete reporting. Validity and reliability testing of the authors' recommendations are required. CONCLUSIONS: Quality appraisal, a necessary step in systematic reviews, is incomplete in most reviews of prognosis studies. Adequate quality assessment should include judgments about 6 areas of potential study biases. Authors should incorporate these quality assessments into their synthesis of evidence about prognosis.

Transvaginal aspiration of ovarian cysts: prognosis based on outcome over a 12-month period.

The success of transvaginal aspiration of ovarian cysts in terms of cyst dimensions, location, and content and the age of the women was evaluated in 35 women aged 17 to 76 years old. Three parameters proved important in predicting the outcome of aspiration: age of the woman (higher age = poorer prognosis for cure), maximum diameter of the cyst (larger diameter = poorer prognosis), and location (left-sided cysts have a poorer prognosis). Prognosis based on outcome indicates aspiration of large cysts should be avoided in older women.

[Agenesis of the corpus callosum. An example of prognosis uncertainty in fetal medicine].

OBJECTIVE: For an increasing number of fetal pathologies, means of diagnosis have progressed faster than knowledge of the prognosis. Decisions are extremely difficult for the medical staff and the parents each time that outcome is uncertain. Agenesis of the corpus callosum, whose diagnosis may be certain through ultrasonography and MRI illustrates this situation well. METHODS: A historical multicentric study enabled us to analyze 37 cases of agenesis of the corpus callosum with a prenatal diagnosis and 10 cases with a post-natal one. RESULTS: Among the 37 prenatal diagnoses, we found 28 cases of medical abortions according to the French law and 9 newborns. Among the 9 newborns, we observed one neonatal death related to an acute fetal distress and 3 post-natal deaths between 1 and 3 months. Among the 10 cases diagnosed after birth, one died, 7 are in good health with a follow-up from 7 months to 6 years and 2 have neurological disturbances. CONCLUSION: Therefore, it seems essential to deepen knowledge of the prognosis and the evolutivity of this affliction in order to give the parents more precise information. However, knowledge of the prognosis is difficult because of the large number of abortions performed for medical reasons. Only a multicentric study, with a long-term pediatric follow-up, will enable us to better understand the prognosis of corpus callosum agenesis.

Hospital prognosis of myocardial infarction with respect to risk factors.

Out of 9922 patients with ischaemic heart disease [IHD] hospitalized during a decade, clinico-pathological data of 796 patients with acute myocardial infarction [MI] were analyzed in detail. With the aid of a logico-probabilistic model, the author made an attempt to quantify the individual risks of the hospital prognosis of MI and to obtain the so-called cumulative risk of MI. The prognostic relevances of the characters investigated were tested by Bayes' theorem. By reducing the matrix "character-disease", the original number of 201 characters was reduced to 34, which were divided into five classes, as follows: a] anamnestic data about the occurrence of risk factors, b] data on coronary pains, c] objective clinical, electrocardiographic, or roentgenological findings, d] duration of the praehospitalization phase, e] patient's sex and age. The cumulative risk [sum of partial risks] amounted to 60% and less in MI with a favourable hospital prognosis [that is, at lethality lesser than 5%]; to 61%--100% with a medium fair hospital prognosis [at lethality from 6% to 30%], and to more than 101% with a poor hospital prognosis [at lethality of 41% and higher]. A comparative test of the prognostic index, performed in a different referral area, showed a relatively good practical usability of the criteria described.

[Molecular marker as an indicator in presaging prognosis of human lung adenocarcinoma].

The paper discusses 93 cases of human lung adenocarcinoma in terms of molecular-epidemiology. The relationship between p21 protein and p53 protein and proliferating cell nuclear antigen (PCNA) was analysed by immunohischemical methods. Prognosis by Cox model was used for prosnosis prediction of adenocarcinoma in human lung. Results showed that the prognosis of adenocarcinoma was poor when of p21 protein expression was positive and the relative ratio was 2.08. However, p53 protein expression was not related to the prognosis of adenocarcinoma. The higher the positive rate of PCNA was, the poorer the prognosis of adenocarcinoma oppeared, with a ratio of 3.27.

Poorer prognosis in young patients with gastric cancer?

BACKGROUND/AIMS: Although the relationship between prognosis and age of patients with gastric cancer is controversial, a poorer prognosis in young patients has been suggested by most investigators. To further examine the hypothesis, a retrospective study was undertaken to analyze a large series of patients with gastric cancer in Taiwan. METHODOLOGY: A total of 1,642 consecutive patients diagnosed with gastric cancer and receiving further management at one medical center from 1988 to 1993 were reviewed. The gender, TNM tumor stage, rate of curative resection and survival of the patients were compared in the young age group (< or = 39 years) and the old age group (> 39 years). Survival was estimated with the product-limit method and difference in survival was tested by the log-rank test. Multivariate analysis was done by the Cox proportional hazard model. RESULTS: Among the 1,642 patients, 61 patients were in the young age group and 1,581 patients were in the old age group. There was no significant difference for the 2 groups of patients in the distribution of TNM stage (stage I: 20%; II: 8%; III: 13%; IV: 59% vs. 19%, 11%, 25% and 45% respectively, in the old age group, p = 0.098) and rate of curative resection (38% vs 51% in the old age group, p = 0.059). The overall 5-year survival showed no significant difference between the 2 groups (25% vs. 29% in the old). Subgroup analyses showed that survival after curative resection and survival without curative treatment (including palliative resection and no resection) also had no difference in the 2 groups. Multivariate analysis also showed that age was not an independent factor. CONCLUSIONS: Although most reports suggested a dismal prognosis in young patients with gastric cancer, based on our findings, young patients (< or = 39 years) do not have a worse prognosis than older patients.

The prognosis of non-critical limb ischaemia: a systematic review of population-based evidence.

BACKGROUND: Peripheral arterial occlusive disease (PAOD) is the most common peripheral vascular disorder in the elderly. A clear picture of the disease's course, especially in patients with non-critical limb ischaemia (Fontaine stages I and II), is essential for the general practitioner, who plays a key role in the diagnosis and management of PAOD. AIM: To evaluate the population-based evidence on the course and prognosis of PAOD. METHODS: An exhaustive literature search yielded 16 population-based studies on the prognosis of PAOD. The methodological qualities of the studies were assessed according to eight criteria. RESULTS: Thirteen studies of high methodological quality show that data on the course, cardiovascular morbidity, and mortality of asymptomatic PAOD are scarce. Only a small group of asymptomatic patients seem to develop intermittent claudication symptoms. However, asymptomatic patients appear to have the same increased risk for cardiovascular morbidity and mortality when compared with claudicants. No data were available on prognostic factors for intermittent claudication and cardiovascular morbidity in asymptomatic patients. The course, cardiovascular morbidity, and mortality of symptomatic PAOD are better documented. A small group of claudicants experience symptom progression. Smoking, hypertension, increasing age, and diabetes are the most relevant risk factors for intermittent claudication. Claudicants are at a higher risk for developing other cardiovascular diseases, resulting in a significantly increased mortality mainly owing to coronary heart disease. Intermittent claudication and a low ankle-brachial pressure index are significant predictors of mortality. Men had intermittent claudication and symptom progression more often than women. Cardiovascular (co-)morbidity was common in both male and female PAOD patients, but male PAOD patients had a higher mortality compared with female PAOD patients. CONCLUSION: Given the current knowledge on the prognosis of PAOD in the general population, an important task for (secondary) prevention is reserved for the general practitioner. Further research is required to document the course and prognosis of asymptomatic PAOD patients.

[Clinical profile and prognosis of bacteremia in patients with cirrhosis based on the Child-Pugh classification].

The characteristics of 70 cases of bacteremia in cirrhotic patients were studied according to the Child-Pugh classification as severity marker of liver involvement. Factors influencing on prognosis were determined. For a comparative analysis, 1,006 cases of bacteremia in non-cirrhotic patients were included. Sixteen patients corresponded to group A, 23 to group B and 31 to group C in the Child-Pugh classification. Patients in group A had a predominance of extra-enteric microorganisms, mainly Staphylococcus aureus (37.5%; p = 0.02), well-defined source (urinary tract, respiratory tract, skin) and good prognosis (mortality rate 6.2%). In contrast, patients in group C had a high recovery rate of Escherichia coli (41.9%) and pneumococcus (19.3%), undetermined source (51.6%; p = 0.05), ascites (83.9%), with or without concomitant peritonitis (41.1%; p = 0.03) and poor prognosis (mortality rate 48.3%; p = 0.008). The characteristics of patients in group B were similar to those of patients in group C but prognosis was as in patients in group A. The immediate mortality rate in the studied patients was 26%. The parameter which best predicted survival in the multivariate analysis was the Child-Pugh classification.

[Angina pectoris and myocardial infarction: sex differences in risk profile, prognosis and referral by family physician].

OBJECTIVE: To detect possible sex differences in risk factors, referrals and prognosis after angina pectoris (AP) and myocardial infarction (MI). DESIGN: Retrospective. METHOD: From 4 general practices in/around Nijmegen, the Netherlands, patients were selected who in 1985-1989 had a first episode of AP or a first MI. Sex differences regarding risk factors, referrals and prognosis were studied by means of patients' files. RESULTS: There were 71 men and 55 women with AP and 97 men and 58 women with MI. Mean age in AP was 69.6 year in women and 63.6 year in men, mean ages in MI were 74.9 and 64.4 year, respectively. Women with MI more frequently suffered from hypertension, AP or CVA/transient ischaemic attack (TIA). Men with MI were referred more often to a specialist than women, but not sooner. Development of cardiovascular co-morbidity after AP and after recovery from a MI were the same for both sexes. Of all patients with a MI 36% suffered a sudden unexpected death, mostly women. CONCLUSION: Women with a first episode of AP and a MI were 6-10 years older than men. Women with a MI suffered more frequently from hypertension, AP and CVA/TIA. The prognosis after angina pectoris showed no sex differences. The prognosis after MI was worse in women than in men.

[Angina pectoris and normal coronary arteries: prevalence and prognosis in men and women].

OBJECTIVE: To determine whether women with anamnestic suspicion of angina pectoris more often than men with suspicion of angina pectoris have normal coronary arteries on coronary arteriograms. Second, to compare the prognosis of these patients with that of the mean population. DESIGN: Literature study. METHOD: Articles were selected from Medline over the period 1966 to May 1998 with the use of search terms, and in De geïnformeerde huisarts (The informed GP) over 1992 to November 1998 following which the relevance of the articles was assessed on the basis of title and abstract. Data on the prognosis of the general population were obtained from a WHO project. RESULTS: Three articles were selected about sex differences in the presence of angiographically normal coronary arteries in patients with suspected angina pectoris. In 2 articles normal coronary arteries were found more often in women (40-41%) than in men (8-12%). In 1 article women were found to have less severe and extensive coronary artery disease then men. Eight articles were selected about the prognosis of patients with suspected angina pectoris and angiographically normal coronary arteries. Per 1000 patient years the total number of deaths ranged from 0 to 6.59 (weighted mean: 4.05), the number of deaths due to coronary disease from 0 to 0.92 (0.47) and the number of patients with non fatal myocardial infarctions from 0 to 1.83 (0.94). These figures were similar to those in an average population. CONCLUSION: Women with anamnestic suspicion of angina pectoris have normal coronary angiograms more often than mean with anamnestic suspicion of angina pectoris. The prognosis of patients with suspected angina pectoris and normal coronary arteries in terms of mortality and number of non fatal myocardial infarctions is the same as in the general population.

[Can the prognosis of multiple sclerosis be predicted?].

Though the global course of the disease is well known when considering large cohorts of patients, it is rather difficult to make a prognosis for a given patient. It is essential however to predict the course of the disease as early as possible in order to be able to give the patient the right treatment at the right time. Age at disease onset is one of the most important clinical predictive factors, as this has been proved by various analyses. The earlier the disease onset, the better the prognosis. The inaugural symptom of optic neuritis, the long interval between the first two relapses, a remitting form at onset are predictive factors of a good evolution. A normal brain magnetic resonance imaging performed on the occasion of a first isolated sign of the central nervous system is the marker of a good prognosis. Conversely, the presence of oligoclonal bands in the cerebrospinal fluid and the increase of IgG index increase the risk of occurrence of a second relapse. The new techniques of magnetic resonance imaging and the exhaustive initial clinical examination using several classifications of disability will allow a better prognosis for a given patient.

[Treatment of choice and long-term prognosis for ventricular arrhythmias].

Treatment of choice and long-term prognosis of the patients with ventricular arrhythmias are described in terms of prevention of sudden cardiac death and/or recurrence of life-threatening arrhythmias(ventricular tachycardia and ventricular fibrillation). 1) As to the long-term prognosis of ventricular tachyarrhythmias, presence of organic heart disease and degree of cardiac dysfunction are major determining factors. 2) The prognosis of patients with ventricular arrhythmias depends on how sudden cardiac death and life-threatening arrhythmias can be prevented. Among various methods, the electrophysiological test and its guided-therapy for antiarrhythmic drugs are now believed to be the most effective method for the prediction and prevention of the life-threatening events. We propose that the signal averaged electrocardiography is the best screening method as non-invasive approach for the selection of patients undergoing the electrophysiological test. 3) There are still certain limitations as to the prediction of sudden cardiac death and/or prevention of recurrent life-threatening arrhythmias by antiarrhythmic drug treatments in the certain numbers of patients depending on their basal cardiac disease and functional impairment. At present, catheter ablation procedure and implantable cardioverter defibrillator are the choice of the treatment in these cases. 4) In addition to conventional antiarrhythmic drugs, the treatment for the basal cardiac condition is mandatory for the long-term prognosis in the patients with ventricular arrhythmias.

[Early prognosis in chronic subdural hematomas. Multivariate analysis of 137 cases].

INTRODUCTION: In the literature there is evidence relating different factors such as age and preoperative clinical condition with prognosis in patients treated surgically for chronic subdural haematoma. OBJECTIVE: To clarify and quantify the magnitude of the factors which determine early prognosis (during hospital admission) of these patients. PATIENTS AND METHODS: We made a prospective study of 137 patients who had been operated on in our centre and found the relationship between different clinical and therapeutic variables with the clinical course and morbidity-mortality by means of multivariate and survival analysis. RESULTS: A high Markwalder functional score (3-4) is an independent factor of poor prognosis (OR = 13.15; CI 95% 6.1-28.4; p = 0.01), as is the presence of a coexisting coagulopathy (OR = 27.2; CI 95% 9.3-79.5; p = 0.01). Advanced age tended to increase the risk (OR = 1.104) but did not reach statistical significance (p = 0.0654). A multivariate logistic model, which included the functional score and presence of coagulopathy, correctly classified 94.7% of the cases studied. Analysis of survival showed two groups with different early mortality as a function of the Markwalder score (high: 3-4 and low: 0-1-2), which could be differentiated statistically (Log-Rank chi squared test: 3.95; p = 0.0468). CONCLUSIONS: The preoperative clinical state classified by functional scores and the presence of underlying coagulopathy are the main prognostic factors in chronic subdural haematoma during hospital admission. Advanced age is probably not in itself an independent factor for bad prognosis.
