Course and prognosis of childhood epilepsy: 5-year follow-up of the Dutch study of epilepsy in childhood.

Knowing the prognosis of epilepsy will undoubtedly influence the treatment strategy. This study aimed to define the prospects of newly diagnosed childhood epilepsy, assess the dynamics of its course, identify relevant variables and develop models to assess the individual prognosis. Four hundred and fifty-three children with newly diagnosed epilepsy were followed for 5 years. Terminal remission at 5 years (TR5) was compared with terminal remission at 2 years (TR2) and with the longest remission during follow-up. Variables defined at intake and at 6 months of follow-up were analysed for their prognostic relevance. In multivariate analyses, combinations of variables were tested to develop reliable models for the calculation of the individual prognosis. Data on treatment, course during follow-up and epilepsy syndromes were also studied. Three hundred and forty-five children (76%) had a TR5 >1 year, 290 (64%) >2 years and 65 (14%) had not had any seizure during the entire follow-up. Out of 108 children (24%) with TR5 <1 year, 27 were actually intractable at 5 years. Medication was started in 388 children (86%). In 227 of these (59%), anti-epileptic drugs (AEDs) could be withdrawn. A TR5 >1 year was attained by 46% on one AED, on the second AED by 19%, and by 9% on all additional AED regimes. Almost 60% of the children treated with a second or additional AED regime had a TR5 >1 year. Variables predicting the outcome at intake were aetiology, history of febrile seizures and age. For intake and 6-month variables combined, sex, aetiology, postictal signs, history of febrile seizures and TR at 6 months were significant. The model derived from intake variables only predicted TR5 <1 year correctly in 36% and TR5 >1 year in 85% (sensitivity 0.65, specificity 0.64). The corresponding values for the model derived from intake and 6-month variables were 43 and 88% (sensitivity 0.69, specificity 0.71). The course of the epilepsy was constantly favourable in 51%, steadily poor in 17%, improving in 25% and deteriorating in 6%. Intractability was in part only a temporary phenomenon. The outcome at 5 years in this cohort of children with newly diagnosed epilepsy was favourable in 76%; 64% were off medication at that time. Almost a third of the children had a fluctuating course; improvement was clearly more common than deterioration. After failure of the first AED, treatment can still be successful. Models predicting the outcome have fewer misclassifications when predicting a long terminal remission than when predicting continuing seizures.

Breast carcinomas fulfill the Warburg hypothesis and provide metabolic markers of cancer prognosis.

The aim of this study was to investigate selected proteomic markers of the metabolic phenotype of breast carcinomas as prognostic markers of cancer progression. For this purpose, a series of 101 breast carcinomas and 13 uninvolved breast samples were examined for quantitative differences in protein expression of mitochondrial and glycolytic markers. The beta-subunit of the mitochondrial H(+)-ATP synthase (beta-F1-ATPase) and heat shock protein 60 (Hsp60), and the glycolytic glyceraldehyde-3-phosphate dehydrogenase, pyruvate kinase and lactate dehydrogenase were identified by immunological techniques. Correlations of the expression level of the protein markers and of the ratios derived from them were established with the clinicopathological information of the tumors and the follow-up data of the patients. The metabolic proteome of breast cancer specimens revealed a pronounced shift towards an enhanced glycolytic phenotype concurrent with a profound alteration on the mitochondrial beta-F1-ATPase/Hsp60 ratio when compared with normal samples. Discriminant analysis using markers of the metabolic signature as predictor variables revealed a classification sensitivity of approximately 97%. Kaplan-Meier survival analysis showed that several of the proteomic variables significantly correlated with overall and disease-free survival of the patients. The expression level of beta-F1-ATPase per se allowed the identification of a subgroup of breast cancer patients with significantly worse prognosis. Multivariate Cox regression analysis indicated that tumor expression of beta-F1-ATPase is a significant marker independent from clinical variables to assess the prognosis of the patients. We conclude that the alteration of the mitochondrial and glycolytic proteomes is a hallmark feature of breast cancer further providing relevant markers to aid in the prognosis of breast cancer patients.

Prognosis and risk stratification after myocardial infarction.

In order to assess prognosis after myocardial infarction, various methods have been used: estimation of ejection fraction, Holter monitoring, detection of ventricular late potentials using signal-averaging techniques, programmed ventricular stimulation of the heart to test the inducibility of ventricular tachyarrhythmias, and parameters that assess heart rate variability. Left ventricular dysfunction is the major determinant for prognosis after myocardial infarction, but left ventricular end-systolic volume may be better than overall ejection fraction. The presence of an 'arrhythmogenic substrate' may be detected by recording low-amplitude, fractionated activity or by artificially introducing premature ventricular extrasystoles using programmed ventricular stimulation. The signal-averaged ECG represents an independent tool for risk assessment. In some studies, signal-averaging and programmed ventricular stimulation proved to be more sensitive for the prediction of sustained ventricular tachycardia than for sudden death. The risk of an arrhythmic event in patients with an abnormal signal-averaged ECG or an abnormal result of programmed ventricular stimulation is increased, although the majority of these patients still do not experience a fatal or life-threatening arrhythmia. This high number of false-positive results limits the practical applicability of the signal-averaged ECG but also of other techniques such as long-term ECG recording. Recent interest has focussed on heart rate variability, which is considered an index of sympatho-vagal interaction after acute myocardial infarction. Patients with decreased heart rate variability have a poorer prognosis than those with normal parameters. Patency of the infarct-related artery is a major factor that governs the potentially beneficial effects of thrombolytic therapy. Many, but not all, studies have shown a reduced prevalence of late potentials after successful thrombolysis or in the presence of an open infarct-related artery. Effective thrombolytic therapy may prevent the development of an abnormal electrophysiological milieu after myocardial infarction. Finally, neurological factors such as depression have been shown to be independent risk factors for mortality after acute myocardial infarction. The role of psycho-social factors and their mechanisms of action need further attention since they open the door for behavioural modification. In conclusion, there are several promising new techniques for identification of patients at risk of ventricular tachyarrhythmias. These techniques seem to be superior to more conventional methods such as long-term ECG monitoring as well as exercise testing. Methods which determine the arrhythmogenic substrate might be combined with a parameter of left ventricular ejection fraction because of the paramount importance of left ventricular pump function. However, due to the large proportion of false-positive results obtained with any of these methods, it seems unlikely that they will clearly surpass the others and be sufficiently accurate for risk assessment in the individual patient.

Rescue of implantation potential in embryos with poor prognosis by assisted zona hatching.

The effect of the assisted zona hatching (AZH) procedure was investigated on 135 cycles with a poor prognosis of pregnancy due to: (i) maternal age > or = 38 years (45 cycles); (ii) three or more failed in-vitro fertilization (IVF) attempts (70 cycles), and (iii) patients possessing both inclusion criteria (20 cycles). The control groups (113 cycles) included patients possessing the same characteristics (42, 53 and 18 cycles respectively) and who did not undergo the AZH procedure. A total of 505 embryos was treated with AZH before transfer, resulting in: 14, 25 and 6 clinical pregnancies. The percentage of clinical pregnancies per cycle was significantly higher than controls for the first (31 vs 10% in control 1, P < 0.05) and second groups (36 vs 17% in control 2, P < 0.05). No significant difference in percentage of clinical pregnancies was found for the third group (30 vs 6%). Similarly, higher rates of implantation were obtained (11.5, 15 and 11%) compared to the respective controls (4%, P < 0.02; 6.3%, P < 0.01; and 1.5%). The rate of miscarriage in the AZH groups was similar to that obtained in the controls (22 vs 21%). Finally, the morphological analysis of the embryos transferred revealed that the poor prognosis condition is associated to a significantly slower rate of development and a higher rate of fragmentation. The present results indicate that AZH procedure improves pregnancy and implantation rates in patients with a poor prognosis of pregnancy by facilitating the hatching process in embryos which would otherwise be trapped inside the zona pellucida.

Prognosis in Kaposi's sarcoma.

We studied and followed up 112 African patients with Kaposi's sarcoma for at least 3 years or until death to determine what features of the disease at presentation most accurately predicted the prognosis. The clinical pattern of disease at presentation was most important. All patients with generalized disease died of their disease; the only deaths among those with nodular disease were due to intercurrent illness. The 3-year survuval rate among patients with locally aggressive lesions with 64%. We could obtain greater refinement of prognosis by noting the response to a dinitrochlorobenzene challenge, the presence of nodal involvement, and the histologic pattern of the tumor. The age and sex of the patient influenced the pattern of disease likely to be found, but the prognosis for a given clinical pattern was the same in both sexes and at different ages.

Altered retinoblastoma protein expression and prognosis in early-stage non-small-cell lung carcinoma.

BACKGROUND: Altered retinoblastoma (RB [also known as RB1]) gene expression was initially found in a small cohort study to occur in five (22%) of 23 patients with primary stage I and II non-small-cell lung carcinomas (NSCLCs). Putative mutation of the p53 gene (also known as TP53) has also been found to occur frequently in stage I and II NSCLCs and to be associated with more aggressive disease and a poorer prognosis. PURPOSE: Our purpose was to determine the Rb protein status in the same cohort that had been previously studied for their p53 protein status and to document whether loss of Rb protein expression was also an important factor in overall survival. METHODS: One hundred one stage I or II NSCLC specimens were analyzed by immunohistochemical staining. These paraffin-embedded tumor sections were obtained from individual paraffin blocks prepared for each patient in the previous study. Patient survival status was obtained from hospital and tumor registry records. RESULTS: Altered Rb protein expression was found in 24 of 101 stage I and II NSCLCs. The median survival was 32 months for patients with Rb-positive (Rb+) tumors and 18 months for individuals in whom expression of Rb protein was absent or altered (Rb-) in tumor cells. Log-rank analysis of the differences in overall survival was statistically significant (P = .007). When these results were combined with the p53 status in the same tumor, the median survival was 12 months for those individuals who had theoretically the worst pattern (Rb-/p53+) and 46 months for those patients with theoretically the best pattern (Rb+/p53-) (P < .001). The Rb+ and Rb- groups in this cohort were well balanced with respect to the distribution of age, disease stage, histologic types, p53 status, and sex. Using a multivariate proportional hazards regression model, both altered Rb and p53 status were found to be significantly associated with poor prognosis (P = .005 and .012, respectively) in the overall cohort. CONCLUSION: Altered Rb protein expression is an independent prognostic marker for overall decreased survival in early-stage NSCLC as detected by absence of nuclear Rb protein staining. There appears to be a poorer prognosis when loss of Rb protein function and mutated p53 protein occur in the same tumor. IMPLICATIONS: If these findings can be confirmed in larger prospective studies, the results would suggest that both the Rb and p53 status should be utilized as independent prognostic factors in early-stage NSCLC.

Tumor biologic factors and breast cancer prognosis among white, Hispanic, and black women in the United States.

BACKGROUND: In the United States, prognosis and survival after the diagnosis of breast cancer is poorer among black patients and, to a lesser extent, among Hispanic patients, compared with white patients. Patients who are black or Hispanic have been reported to present with higher stage or more advanced disease. Even after adjusting for stage, however, survival rates are lower for blacks but not for Hispanics. PURPOSE: Our purpose was to compare survival, age, tumor size, nodal status, estrogen-receptor (ER) and progesterone-receptor (PgR) status, histologic type, S-phase fraction, DNA ploidy status, HER-2/neu protein expression, and p53 protein status, along with systemic treatment, in a large group of white, black, and Hispanic U.S. women. METHODS: From 1970 to 1991, breast tumor specimens were submitted to The University of Texas Health Science Center from 31 contributing hospitals throughout the United States for ER and PgR assay. A total of 4885 white, 1016 black, and 777 Hispanic women were eligible for this study. Median follow-up was 57 months. RESULTS: Overall, white women were significantly more likely to be older and to have smaller tumors, have less lymph node involvement, have tumors with positive ER and PgR status, and have a lower S-phase fraction compared with Hispanic or black women. There were no clinically important differences in DNA ploidy, histologic type, HER-2/neu, and p53 expression among the three groups. Considering all stages, white women had the best overall survival (date of diagnosis to date of death) at 5 years--75% +/- 1% (means +/- SE), with a median survival of 166 months, but Hispanic women had an intermediate survival--70% +/- 2% (median survival, 156 months), and black women had the worst survival--65% +/- 2% (median survival, 117 months) (P < .0001). For node-negative patients, there was no significant difference in disease-free survival (date of diagnosis to date of first recurrence) or overall survival, although blacks tended to have a worse prognosis. For node-positive or locally advanced disease and for metastatic disease, blacks had significantly (P < .0001) worse disease-free and overall survival than did white or Hispanic women. Differences in the use of systemic therapy did not explain these outcomes. CONCLUSION: A number of biologic factors associated with poor prognosis are found with a significantly increased frequency in breast tumors from Hispanic and, particularly, from black women. Tumors with a more aggressive biology could lead to a higher stage at diagnosis and a poorer survival for the group as a whole.

Has the prognosis for patients with pauci-immune necrotizing glomerulonephritis improved?

BACKGROUND: Over the past 14 years, important advances have been made in diagnosis and treatment of patients with pauci-immune necrotizing glomerulonephritis (PINGN). The present study set out to evaluate the impact of these advances on prognosis by comparing patient survival during the period 1985-1995 with previously reported results for such patients between 1975 and 1982. METHOD: A retrospective analysis was carried out at two affiliated inner-city renal units on all patients considered to have PINGN during the period 1985 1995. Details of renal and extra-renal disease at presentation and during follow-up, along with treatment regimes, were noted. Figures for renal and patient survival were compared with those previously reported from one of these units. RESULTS: A total of 47 patients were diagnosed over the period 1985 1995, with a median age of 57 years. The overall patient survival (+/- standard error) at 1 and 5 years was 72.3 (+/- 0.06) and 51.2% (+/- 0.12) respectively, with corresponding renal survival (alive and independent of renal replacement therapy) at these times of 61.7 (+/- 0.07) and 49.9% (+/- 0.09) respectively. We identified increased age at presentation and advanced renal failure (requiring dialysis or serum creatinine > 300 micromol/l) as predictors of reduced patient and renal survival. When comparing our results with those previously reported (1975-1982), we found no improvement in prognosis for patients with PINGN during the latter period. CONCLUSIONS: These results suggest that the prognosis for patients with PINGN has not improved despite diagnostic and therapeutic advances. Delay in diagnosis and treatment may compromise the therapeutic potential in PINGN.

Clinical demographics and long-term prognosis after stroke in patients on chronic haemodialysis. The Okinawa Dialysis Study (OKIDS) Group.

BACKGROUND: Stroke is one of the leading causes of death in chronic dialysis patients. However, few epidemiological studies have reported on the demographics and long-term prognosis after stroke. METHODS: We have observed the occurrence of stroke in the chronic dialysis population for the past 10 years in Okinawa, Japan. Definite cases of stroke were registered and categorized as cerebral haemorrhage (CB), cerebral infarction (CI), and subarachnoid hemorrhage (SAH). RESULTS: Among 3741 chronic dialysis patients (2073 men, 1668 women), 271 patients (164 men, 107 women) had strokes (CB 162, CI 97, SAH 12) at least once during the study period from 1 April 1988 to 31 March 1998. The total duration of observation was 15 pound 748.8 patient-years (males 8990.5, females 6758.3). The incidence of stroke per 1000 patient-years was 17.2 overall, 10.3 for CB, 6.2 for CI, and 0.8 for SAH. Twenty-four per cent of stroke cases occurred within 1 year of starting dialysis therapy, and 57.7% occurred within 5 years after the beginning of therapy. The mean (SD) age at onset of stroke was 59.8 (13.0) years overall, 57.2 (12.6) for CB, 65.0 (12.1) for CI, and 53.6 (13.0) years for SAH. The survival rates after stroke were 53.4% at 1 month, 43.5% at 6 months, 35.7% at 12 months, and 23.2% at 60 months. Patients with diabetes mellitus (DM) had higher incidence of CI and a poorer prognosis than those without DM. CONCLUSION: Incidence of stroke was high (17.2 per 1000 patient-years) in the dialysis population of our area and the long-term prognosis after stroke was poor.

Immediate and long-term prognosis in acute renal failure in the elderly.

Acute renal failure (ARF) is particularly frequent in the elderly. A few studies have reviewed immediate prognosis of ARF in older patients, but these do not allow any conclusion on long-term renal prognosis. Our retrospective study included 46 patients over 65 years referred to our renal unit between 1983 and 1989. Survivors were followed up 6-71 months after discharge (mean: 39 months). The evolution of renal function was evaluated by measurement of serum creatinine. Data analysis employed chi 2 with Yates correction, Student t, and Mann-Whitney tests to compare survivors and deceased, and to compare patients with normal and abnormal renal function at follow-up. During hospitalisation 11 patients (24%) died. Our univariate analysis reveals that three variables independently influence mortality: consciousness disturbance (P less than 0.001), high urea concentration (P less than 0.01), and hypoalbuminaemia (P less than 0.001). Age does not adversely affect prognosis. At follow-up 15 patients (43%) had a complete functional recovery, eight (23%) had incomplete renal recovery and two (6%) were on chronic haemodialysis. These results are similar to those observed in a younger population. In conclusion we believe that age alone should not be used to predict the immediate survival or the long-term renal outcome in ARF in the elderly.

Physiological parameters during the initial stages of cardiopulmonary exercise testing in patients with chronic heart failure. Their value in the assessment of clinical severity and prognosis.

AIMS: To analyse the relationship between initial exercise parameters and peak oxygen consumption and prognosis in 96 patients with congestive heart failure. METHODS AND RESULTS: Comparison of responses during the initial 6 min of cardiopulmonary exercise testing (Naughton modified protocol) in patients stratified to the Weber classification, and analysis of their predictive value with respect to peak oxygen uptake and prognosis. All patients had a left ventricular ejection fraction < 0.45 and a valid cardiopulmonary exercise test, during which they remained in sinus rhythm. Significant differences in several parameters were seen in the initial stages, including oxygen pulse (P < 0.04) and ventilation equivalent for oxygen (P < 0.004). These parameters remained as independent predictors of peak oxygen uptake in the algorithm derived from baseline and initial stage variables. In a multivariate Cox proportional hazards model, the predicted peak oxygen uptake (P < 0.003) was an independent predictor of mortality. CONCLUSION: In patients with congestive heart failure, the initial 6 min parameters of a cardiopulmonary exercise test have additional value in the assessment of clinical severity and prognosis. This may be of clinical relevance since a limited incremental exercise protocol may be more objective than more traditional 6 min walking tests and less demanding.

Submaximal early exercise test compared to clinical findings for evaluation of short- and long-term prognosis after the first myocardial infarction. Result from the MONICA Projects in Augsburg and Toulouse.

Clinical and ergometric data were derived from 1098 consecutive exercise tests in patients with a first acute myocardial infarction between 1974-1983. In 1992 a follow-up was performed in order to analyse the importance of a submaximal early exercise test, in combination with clinical data, for the prediction of short- and long-term prognosis of cardiovascular death. The relative value of 20 clinical variables, including medical history, markers of infarction size, medication etc., and 28 variables at exercise test were studied. Univariate, multivariate and survival analysis, for estimation of prognosis and independent prediction of cardiovascular death was used. Independent clinical risk factors for cardiovascular death were (1) Within 1 year: relative heart volume (ml.m-2 body surface area) on chest X-ray. (2) Long-term mortality: maximum heart rate and relative heart volume, diabetes, age and digitalis medication. Independent exercise risk factors were: (1) Within 1 year: heart rate, ventricular arrhythmia and ST depression > or = 1 mm before exercise, diastolic blood pressure at maximum exercise and target heart rate. (2) Long-term mortality: angina pectoris and/or ST depression > or = 1 mm at maximum exercise. In subgroups of patients with clinical risk factors, mortality risk increased if there were signs of angina pectoris and/or ST depression > or = 1 mm during exercise. The risk increased 100% in diabetics, 91% with age > 70 years, 58% with relative heart volume > or = 500 ml.m-2 body surface area, 42% with heart rate > or = 100 at admission, and 34% with digitalis medication. No increase was found in the subgroup of patients without clinical risk factors. Thus, submaximal early exercise stress testing provides important information for short- and long-term prognosis in patients after the first acute myocardial infarction compared to clinical evaluation alone.

Clinical findings and prognosis of polyarteritis nodosa and Churg-Strauss angiitis: a study in 165 patients.

Factors influencing the prognosis were studied in 165 patients with polyarteritis nodosa (PAN) and Churg-Strauss angiitis. One hundred and forty-seven of the patients fulfilled histological and/or arteriographic diagnostic criteria, and in 18 patients the diagnosis was based on clinical criteria. The patients' mean age on diagnosis was 48.4 +/- 16.4 years. The main symptoms were fever (69%), weight loss (66%), arthritis (44%), mononeuritis multiplex (67%), cutaneous signs (46%), renal involvement (26%), gastrointestinal symptoms (31%), asthma (29%), hypertension (31%) and cardiac failure (18%). Ninety-two per cent of the patients survived for at least 1 year after diagnosis of the disease, 79% for 2 years, and 63% for 5 years. The immediate causes of death were gastrointestinal bleeding or peritonitis in 11 cases, pancreatitis in two, renal insufficiency in six, cardiac failure in five, infectious complications in four, stroke in three and other causes in 11. We studied the prognosis of necrotizing angiitis in relation to clinical symptoms and laboratory findings. The association of four conditions were associated with a poor prognosis: age over 50, gastrointestinal problems, cardiomyopathy and renal signs. The survival rates in patients with these conditions were: for gastrointestinal problems, 55% 5-year survival (versus 67%); and for age over 50, 68% 3-year survival (versus 78%; p less than 0.09). One hundred and fifty-nine patients were treated with steroids for at least 18 months. Forty-eight also received cytotoxic agents (27%) and 46 plasma exchange. Patients who were treated with plasma exchange and prednisone were randomly assigned to additional treatment with cyclophosphamide. Survival rates were comparable in both groups.

Predicting prognosis of gastrointestinal smooth muscle tumors. Role of clinical and histologic evaluation, flow cytometry, and image cytometry.

Both flow cytometry (FCM) and morphometry have been proposed as techniques for predicting the prognosis of gastrointestinal (GI) smooth muscle tumors (SMTs). In particular, DNA aneuploidy by FCM has been associated with high histologic grade and shortened survival, whereas the DNA index determined by image cytometry has been proposed as a criterion for the diagnosis of malignancy. To further define the potential roles of these two techniques, we performed a variety of morphometric and FCM measurements on paraffin blocks from 122 patients with GI SMTs, with a median follow-up period of 6 years, together with assessments of tumor size and mitotic activity. None of the morphometric measurements (nuclear perimeter, area, form factor, longest diameter, average ferret diameter, equivalent diameter, and DNA index) was a significant prognostic factor when analyzed using a univariate Cox model. In contrast, the flow cytometric mean channel number, the fraction of cells in G2M, aneuploidy of the G0/G1 peak, aneuploidy of the G2M peak, tumor size, and mitotic activity index were statistically significant in univariate models, together with the patient age and sex, and whether or not the patient presented with metastases. In a multivariate model, > 10 mitotic figures per 50 high-power fields and metastases indicated a poor prognosis. If metastasis was not allowed to enter the model, the mitotic index and aneuploidy of the G2M peak portended a poor prognosis.

Immunohistochemical expression patterns of germinal center and activation B-cell markers correlate with prognosis in diffuse large B-cell lymphoma.

Recent studies with cDNA microarrays showed that diffuse large B-cell lymphoma (DLBCL) cases with gene expression profiles similar to germinal center (GC) B cells had much better prognosis than DLBCL cases with gene expression profiles resembling activated B cells. The goal of the current study is to evaluate if using a panel of GC B-cell (CD10 and Bcl-6) and activation (MUM1/IRF4 and CD138) markers by immunohistochemistry defines prognosis in patients with de novo DLBCL. Immunohistochemical stains for the above markers were performed on paraffin-embedded tissues from 42 de novo DLBCL patients. Median follow-up in all patients was 41 months (range, 1-103 months) and in surviving patients was 65 months (range, 14-103 months). These cases could be classified into three expression patterns: GC B-cell pattern (pattern A) expressing CD10 and/or Bcl-6 but not activation markers; activated GC B-cell pattern (pattern B) expressing at least one of GC B-cell markers and one of activation markers; and activated non-GC B-cell pattern (pattern C) expressing MUM1/IRF4 and/or CD138 but not GC B-cell markers. Patients with pattern A had much better overall survival than those with the other two patterns (Kaplan-Meier survival analysis, P < 0.008, log rank test). Using multivariate Cox proportional hazards regression analysis, the international prognostic index scores and the expression pattern of these markers were independent prognostic indicators. Our results suggest that expression patterns of this panel of GC B-cell and activation markers by immunohistochemistry correlate with the prognosis of patients with DLBCL. Immunohistochemical analysis on paraffin-embedded tissues is more readily available than gene expression profiling by cDNA microarray and may provide similar prognostic information.

Prognosis in stage II (T1N1M0) breast cancer.

As part of a detailed study of prognostic factors in breast cancer, we have analyzed the ten year survival rates of 524 patients with primary invasive carcinomas 2.0 cm or less in diameter (T1). This report describes the subset of 142 patients (27%) who had metastases only in axillary lymph nodes (T1N1M0). All the patients were treated initially by at least a modified radical mastectomy. Factors associated with a significantly poorer prognosis were: axillary lymph node metastases suspected on clinical examination; perimenopausal menstrual status at diagnosis; tumor larger than 1.0 cm; prominent lymphoid reaction; infiltrating duct or lobular rather than medullary, colloid and tubular carcinoma; and blood vessel invasion. When compared with those patients with negative nodes (T1N0M0), the patients with one or more lymph node metastases had a significantly poorer prognosis. Generally, survival rates tended to diminish as the number of involved lymph nodes increased. In this respect, comparison of patients with one-three and four or more nodal metastases provided a significant discrimination of prognostic groups in the entire series. However, for patients with disease limited to Level I, the same discrimination was obtained comparing those with one-two and three or more positive nodes. In the subset with a single lymph node metastasis, the size of the metastasis (micro or less than or equal to 2 mm vs macro or greater than 2 mm) was not significantly related to prognosis. Lymph node metastases were significantly less frequent among tumors smaller than 1 cm and special tumor types (medullary, colloid, lobular and tubular). However, no factor proved to be a reliable predictor of the presence of axillary metastases for the single largest group consisting of patients with infiltrating duct carcinoma 1-2 cm in diameter.

Hepatic resection for hepatocellular carcinoma. Clinical features and long-term prognosis.

Ninety-eight hepatic resections for hepatocellular carcinoma were performed on 94 patients from 1963-1985. HBs antigen was positive in 17% of patients, preoperative serum alpha-fetoprotein was more than 20 ng/mL in 70% of patients, and liver cirrhosis was present in 75% of patients. Hospital mortality rate was 19%, and the volume of operative blood loss was the most decisive factor that affected the short-term prognosis. Excluding the 19 hospital deaths, the long-term survival rates of 75 patients were 73%, 42%, and 25% for 1, 3, and 5 years, respectively. Prognostic factors that influenced the long-term prognosis were investigated by comparing the survival curves. Significant differences of survival patterns were noted when analyzed on the basis of preoperative alpha-fetoprotein level (less than or equal to 200 vs. greater than 200 ng/mL), tumor size (less than or equal to 5 vs. greater than 5 cm), and tumor capsule. The recurrence of carcinoma was the main cause of death in 56% (42 patients) who died after discharge from the hospital. The development of effective prevention and treatment against recurrent tumors is necessary to improve long-term prognosis.

Impact of the fibrinolytic enzyme system on prognosis and survival associated with non-small cell lung carcinoma.

Comprehensive studies of fibrinolysis in non-small cell lung carcinoma have been limited, and assignment of patients to high/low prognosis groups based on arbitrary cut-offs utilizing fibrinolytic measurements is unstandardized. This study was performed in 166 patients to examine the effects of cut-off values determined in three ways. Model 1 assigned patients to one of three equal groups (low, medium, high) based on fibrinolytic measurements made at diagnosis, Model 2 divided patients into low/high groups using median values, and Model 3 grouped according to the parameter being above/below normal range. In model 1, raised plasma fibrinogen, D-dimer and soluble fibrin were positively associated with poorer survival. In model 2, tissue plasminogen activator antigen was additionally related to poorer prognosis. Model 3 identified seven parameters as significantly related to survival, two not identified by the other models becoming significant [plasmin-antiplasmin, tissue plasminogen activator inhibitor-1 (PAI-1) antigen]. Using multivariate analysis, plasma fibrinogen level was the most uniformly significant parameter. Relative risk estimates indicated that raised plasma fibrinogen, soluble fibrin and D-dimer were associated with increased risk of death. Use of the normal/above normal cut-off is recommended to provide the maximum number of significant parameters relating to prognosis, and increased plasma D-dimer, PAI-1 antigen and fibrinogen were most closely related to survival/prognosis.
