Coronary arteriography in 486 patients--arteriographic pathology and prognosis.

The coronary arteriographic findings and prognosis in a series of 486 non-surgically treated patients were analyzed. A semiselective injection was used. The number and causes of deaths were obtained from the census registry after a follow-up period of 7--12 years. The material comprised normal arteriograms in 26% of the patients, wall irregularities at most in 17%, obstruction of at least half the diameter in 37%, and unclassifiable arteriograms in 19%. A mean of 1.8 obstructed arteries per patient was found in the group with obstructive arterial lesions and among these patients the left anterior descending artery was most often engaged. In the same group the cardiac mortality at seven years was 20%. There were no significant differences between deceased and survivors with regard to clinical data. The arteriograms themselves offered more information about the prognosis. Normal arteries or wall irregularities at most implied excellent prognosis with regard to death in coronary heart disease. The seven-year mortality was 36% among patients with coronary artery occlusions, which is significantly higher than 14% among those with arterial stenosis. Materials from the USA and Canada have displayed a much higher mortality than our study in spite of comparable arteriographic findings.

Atrial fibrillation--a review of course and prognosis.

Four recent major studies concerning the prognosis in atrial fibrillation (AF) are reviewed. The one-year mortality ranged from 16.0 to 0.2%, highest in elderly, hospitalized patients with chronic AF and lowest in young individuals with paroxysmal AF without other heart disease. The recognized clinical impression that the prognosis in AF is determined by age, type of AF and clinical status is thus confirmed. In three studies, however, the prognosis in lone atrial fibrillation seemed to be poorer than previously thought. The overall rate of thromboembolic complications in AF was about 25% in several studies. The effectiveness of coumarin drugs in the prophylaxis of these complications is not proved, and the time has come to subject them to more careful clinical investigation.

Immune phenotype and prognosis in chronic B-lymphocytic leukaemia and leukaemic immunocytoma.

Fifty-nine patients with a leukaemic B-lymphocytic malignancy ("CLL") were studied. According to the Kiel classification, 29 patients had chronic lymphocytic leukaemia (CLL) and 30 had immunocytoma (IC). Cell surface immunoglobulin staining showed mu heavy chain phenotype in 14 patients, mu in 35, gamma in 7; in cells from 3 patients the staining was too weak to permit identification. The light chain phenotype was kappa in 39 patients, lambda in 17, and unidentified in 3. The immunoglobulin isotypes differed between the diagnoses. The gamma chain phenotype was found only in IC patients (p less than 0.02), and more CLL than IC patients showed a lambda chain phenotype (p less than 0.04). Blood lymphocytes from IC patients contained more T cells than CLL cell samples (p less than 0.002). No prognostic difference was found between the CLL and IC group. Compared to the lambda phenotype, the kappa phenotype was associated with a poorer prognosis in the IC group, but with a better prognosis in the CLL group. IC patients with mu phenotype had a poorer prognosis than those with gamma phenotype. Low relative T cell numbers were associated with a poor survival (p less than 0.01).

The incidence and prognosis of cerebrovascular disease in hospital patients in Helsinki, Finland, in the decade 1970-1980.

Over 21,000 hospital episodes due to cerebrovascular disease (CVD, ICD-8 nos. 430-438) were registered in the Helsinki hospitals in 1970-1980. Of those 17,629 were identified as new cases. The age-adjusted incidence of haemorrhagic and thrombotic stroke (430-433) declined during the period 1970-1975 from 221 to 139 cases/100,000 inhabitants, whereafter no further decrease was observed. The decline in incidence was significant in both sexes. Analysis by diagnosis group showed that the decrease was confined to the incidence of haemorrhagic stroke (430-432), whereas the incidence of thromboembolic stroke (433, 434) and transient ischaemic attacks (435) remained virtually unchanged. Survival was mainly determined by patient age and type of CVD. Intracerebral haemorrhage and occlusion of precerebral arteries exhibited the poorest short-term prognosis. About half of the patients hospitalised due to cerebral thrombosis and embolism survived over one year. Long-term prognosis of the major CVD groups was very poor with only 10% of the patients alive after eight years. Transient cerebral ischaemia and subarachnoid haemorrhage had a clearly better prognosis, the survival rates after eight years being 45 and 30%, respectively.

Determinants of prognosis in breast cancer patients with tumor involvement of the skin (pT4b).

Determinants of prognosis were studied in patients with breast cancer with histologically proven tumor extension to the skin without clinical evidence of distant metastases (i.e., pT4b N0-3 M0). Data were collected retrospectively on 77 consecutive patients diagnosed in one community teaching hospital over the period from 1980 to 1995. The prognostic factor of tumor size showed a 5-year survival rate for patients with a tumor </=3 cm of 81% compared to 45% for patients with tumors larger than 3 cm (p = 0.002). Achievement of complete remission resulted in a 5-year survival rate of 66%, compared to 27% when complete remission was not achieved (p = 0.005). Another important prognostic factor was the development of local-regional recurrence: the 5-year survival rates for patients with and without local-regional recurrence were 39% and 87%, respectively (p < 0.001). Development of local-regional recurrence was also significantly related to tumor size (p = 0.02). Pathologic tumor size and the achievement of complete remission and local-regional control appear to be the most important prognostic factors for survival in patients with pT4b breast cancer without distant metastases. We conclude that the finding of a pT4b breast cancer does not always imply a dismal prognosis, especially for those patients with a tumor </=3 cm. A favorable prognosis can be expected when treatment is effective in achieving complete remission and in preventing the development of local-regional recurrence.

Clinicopathologic characteristics and prognosis of breast cancer patients associated with pregnancy and lactation: analysis of case-control study in Japan.

Clinicopathologic characteristics and prognosis of breast cancer patients associated with pregnancy and lactation were clarified by means of a case-control study of matched non-pregnant and non-lactating patients with breast cancer. From 18 institutions in Japan, a total of 192 subjects with breast cancer diagnosed during pregnancy (72 cases) and lactation (120 cases) were collected between 1970 and 1988, accounting for 0.76% of all breast cancer patients. The duration of symptoms was longer and tumor size was larger in the study subjects. Although the disease-free interval was longer than that in the control patients, the survival time was shorter. There was no characteristic difference in histologic type. Vascular invasion and lymph node metastasis were found more frequently in the subjects. The positive rates of estrogen receptor and progesterone receptor were lower in the subjects. The 5- and 10-year survival rates of the study patients were 65% and 55%, respectively, and these survivals were significantly lower than those of the control (P < 0.001). The survival rates were poorer in the subjects, in accordance with stage and lymph node metastasis. The results suggest that most of the patients with breast cancer diagnosed during pregnancy and lactation are in a more advanced stage because of a delay in detection and diagnosis, and hence have unfavorable prognosis. Therefore, it is important to diagnose and treat early for improvement of prognosis in patients with breast cancer during pregnancy and lactation.

Immunohistochemical localization of P-glycoprotein and expression of the multidrug resistance-1 gene in human pancreatic cancer: relevance to indicator of better prognosis.

We investigated immunohistochemical localization of P-glycoprotein (P-gp) on paraffin-embedded sections from 103 cases of previously untreated pancreatic tumors and also analyzed multidrug resistance-1 (MDR1) gene expression by polymerase chain reaction after reverse transcription in 35 cases. High positive staining for P-gp was observed in 72.8% of pancreatic tumors and in 73.2% of ductal adenocarcinoma. In ductal adenocarcinoma, immunoreactivity of P-gp was inversely correlated with biological aggressiveness of tumors determined by histologic grading (P<0.01), tumor size (P < 0.01), retroperitoneal invasion (P < 0.01) and portal invasion (P < 0.05). Expression of the MDR1 gene was detected in all the pancreatic tumors examined and was significantly higher than that in normal pancreas (P < 0.05). The levels of MDR1 mRNA showed a moderate correlation with those of P-gp (r=0.62, P<0.0001). Higher expression levels of MDR1/P-gp significantly correlated with better prognosis of patients with ductal carcinoma (P < 0.05). Among patients with ductal carcinoma, the high staining group for P-gp revealed a 3.5-fold better prognosis compared with the low staining group (HR=3.47, 95% CI=1.62, 7.45; P=0.0016). In conclusion, MDR1 gene/P-gp expression in pancreatic cancer without chemotherapy inversely correlates with biological aggressiveness and is an independent indicator of favorable prognosis.

Allelic loss of chromosome 16q in endometrial cancer: correlation with poor prognosis of patients and less differentiated histology.

Deletion of certain chromosomal regions can be demonstrated in malignant cells. Chromosome 16q is one of the regions where allelic loss is frequently detected in carcinoma of the breast and many other tumors, suggesting that gene(s) which retard tumor growth may exist here. To elucidate the clinicopathological significance of chromosome 16q, loss of heterozygosity (LOH) was investigated using microsatellite polymorphism analysis in 58 patients with endometrial lesions (50 with endometrial carcinoma and 8 who had hyperplasia with or without atypia). When 11 regions of chromosome 16q were examined, LOH was found in 20 patients with carcinoma (40%) and none of the patients with hyperplasia. The tumors of 9 of the 20 patients (45%) showed total loss of 16q, while the others (55%) showed partial deletion. Tumors with LOH were histologically less differentiated than those without LOH (P = 0.038, chi2 test). Patients with tumors showing LOH of 16q had a worse prognosis than those without LOH according to Kaplan-Meier survival analysis (P=0.0158, log-rank test). In addition, LOH of 16q showed a significant relationship to prognosis by Cox regression analysis. Deletion mapping of 16q demonstrated that two regions (16q22.1 and 16q22.2-23.1) were frequently involved. Patients with 16q22.1 LOH had a poorer prognosis than those with intact 16q22.1 (P=0.0003, log-rank test). These findings suggest that gene(s) of which defect is possibly related to the aggressiveness of endometrial cancer are localized on a limited region of 16q that includes 16q22.1.

Inactivation of O6-methylguanine-DNA methyltransferase in human lung adenocarcinoma relates to high-grade histology and worse prognosis among smokers.

To evaluate the significance of O6-methylguanine-DNA methyltransferase (MGMT) activity in the development of human lung adenocarcinoma (AC), we investigated promoter hypermethylation of the MGMT gene by methylation-specific PCR, and the expression of MGMT protein by immunohistochemistry in relation to smoking history of the patients. In total, 31 of 87 AC patients (35.5%) showed hypermethylation of the MGMT gene, and no significant difference was observed between smokers (37.3%) and non-smokers (33.3%). However, hypermethylation of the MGMT gene increased in parallel with lesser differentiation grade of tumors among smokers (well, 16.7%; moderately, 42.1%; poorly, 57.1%; P = 0.022), although this trend was not observed among non-smokers. Almost all the tumors with promoter hypermethylation of the MGMT gene showed consistently negative MGMT staining by immunohistochemistry. When the prognosis of stage-I patients was compared among smokers, it was apparent that the prognosis of patients with inactivated MGMT was worse than that of MGMT-positive patients (P = 0.036). Such differences in the prognoses were not observed among non-smokers. In conclusion, MGMT inactivation is related to the differentiation grade and the prognosis of lung AC patients among smokers. Although further studies are required, we speculate that smoking may induce hypermethylation, not only of the MGMT gene, but also of other important tumor suppressor genes.

Systematic review: The model for end-stage liver disease--should it replace Child-Pugh's classification for assessing prognosis in cirrhosis?

BACKGROUND: Prognosis in cirrhotic patients has had a resurgence of interest because of liver transplantation and new therapies for complications of end-stage cirrhosis. The model for end-stage liver disease score is now used for allocation in liver transplantation waiting lists, replacing Child-Turcotte-Pugh score. However, there is debate as whether it is better in other settings of cirrhosis. AIM: To review studies comparing the accuracy of model for end-stage liver disease score vs. Child-Turcotte-Pugh score in non-transplant settings. RESULTS: Transjugular intrahepatic portosystemic shunt studies (with 1360 cirrhotics) only one of five, showed model for end-stage liver disease to be superior to Child-Turcotte-Pugh to predict 3-month mortality, but not for 12-month mortality. Prognosis of cirrhosis studies (with 2569 patients) none of four showed significant differences between the two scores for either short- or long-term prognosis whereas no differences for variceal bleeding studies (with 411 cirrhotics). Modified Child-Turcotte-Pugh score, by adding creatinine, performed similarly to model for end-stage liver disease score. Hepatic encephalopathy and hyponatraemia (as an index of ascites), both components of Child-Turcotte-Pugh score, add to the prognostic performance of model for end-stage liver disease score. CONCLUSIONS: Based on current literature, model for end-stage liver disease score does not perform better than Child-Turcotte-Pugh score in non-transplant settings. Modified Child-Turcotte-Pugh and model for end-stage liver disease scores need further evaluation.

The prognosis of patients with lymphomatoid papulosis associated with malignant lymphomas.

Lymphomatoid papulosis (LyP) is a disorder which generally runs a benign course, but can sometimes be associated with a malignant lymphoma. Information about the prognosis of these LyP-associated lymphomas is, however, fragmentary. In this study, the clinical data of 50 LyP-associated malignant lymphomas, including 11 patients of our own group and 39 reported in the literature, are evaluated. Three main groups of LyP-associated malignant lymphomas could be distinguished: cases associated with mycosis fungoides (19/50 cases). Hodgkin's disease (12/50 cases) and (CD30+) large-cell lymphomas (16/50). The results of this study demonstrate that patients with mycosis fungoides. Hodgkin's disease, and (CD30+) large-cell lymphomas limited to the skin have a favourable prognosis. However, the prognosis of patients developing a systemic (CD30+) large-cell lymphoma proved generally poor. The results of this study also indicate that the risk of an individual LyP patient developing systemic lymphoma is less than 5%.

Expression of thyrotrophin receptor gene in thyroid carcinoma is associated with a good prognosis.

OBJECTIVE: The clinical course of thyroid carcinoma is very variable. It is well known that thyroid carcinomas of similar histology can behave differently in terms of local invasion and distant metastases: there is no reliable way to predict the disease course with confidence. In the present study we compared the TSH receptor and c-myc mRNA levels in different stages of thyroid carcinomas to identify whether they are useful markers for thyroid tumour biological behaviour and prognosis. DESIGN: Thyroid tumour specimens were used as the source of RNA. The TSH receptor and c-myc mRNA levels were detected by Northern blot analysis and quantitated by laser densitometry. PATIENTS: Thyroid tissues were obtained from five patients with multinodular goitres, 22 with differentiated and three with anaplastic carcinomas. MEASUREMENTS: Total cellular RNA was extracted from thyroid tissue specimens and blotted onto nylon membranes. Northern blot analysis was used to detect TSH receptor and c-myc mRNA. The mRNA levels were then quantitated by laser densitometry and compared with each disease stage. RESULTS: TSH receptor mRNA levels were significantly lower in carcinomas as compared to benign tumours. With advancing disease stage, the neoplastic tissues generally showed a progressive decline in TSH receptor mRNA levels. Interestingly, in two specimens from patients with distant metastases, TSH receptor mRNA levels were not significantly reduced and were comparable to those in benign tumours. Both patients are still alive, one of them 18 years after operation, indicating that tumour histology is dissociated from its biological behaviour. c-myc mRNA levels were increased but not significantly so in stage 1-3 carcinomas. However, in stage 4 carcinomas c-myc expression was significantly increased. Thus c-myc overexpression is associated with poor prognosis. Although there is a negative correlation between TSH receptor and c-myc mRNA levels, the correlation was not significant. CONCLUSIONS: These results indicate that decreased TSH receptor and increased c-myc gene expression levels are associated with thyroid cell de-differentiation. They are useful markers for thyroid tumour de-differentiation and disease prognosis.

Cytokine gene polymorphisms and breast cancer susceptibility and prognosis.

Single nucleotide polymorphisms (SNPs) in the promoter regions of cytokine genes are associated with differential levels of cytokine expression. We hypothesized that these SNPs might influence breast tumour development and progression by affecting the efficiency of the antitumour immune response and/or pathways of angiogenesis. A total of 144 female breast cancer patients and 263 cancer-free population controls were genotyped for the interleukin (IL)-1beta-511 (T/C), IL-6 -174 (G/C), tumour necrosis factor (TNF)-alpha-308 (A/G), IL-10 -1082 (A/G), IL-8 -251 (A/T) and vascular endothelial growth factor (VEGF) -1154 (A/G) SNPs, using amplification refractory mutation system polymerase chain reaction (ARMS-PCR) and TaqMan (Applied Biosystems, Foster City, CA, USA) 5' nuclease assays for allelic discrimination. No significant associations were seen. Patient-control comparisons revealed a non-significant trend for association between the TNF-alpha-308 GG genotype and breast cancer compared to controls (79.7 vs. 68.2%, P = 0.03, Pc = 0.54). Stratification of the patient group according to the Nottingham Prognostic Index and individual prognostic factors revealed trends for association between IL-6 -174 GC and IL-8 -251 AA genotypes and markers of poor prognosis (P = 0.04, Pc = 0.72 and P = 0.02, Pc = 0.36, respectively). There were also trends for associations between VEGF -1154 AG and IL-1beta-511 TC genotypes and markers of good prognosis (P = 0.02, Pc = 0.36 and P = 0.05, Pc = 0.90, respectively). These results suggest that the role of cytokine promoter SNPs in both susceptibility to and prognosis in breast cancer requires further investigation in a larger study.

Ulceration and prognosis in cutaneous malignant melanoma.

A review of 1818 patients with cutaneous malignant melanoma revealed that for both patients with localized disease (clinical stage I) and those with regional lymph node metastases at first presentation (clinical stage II), ulceration of the primary lesion was a poor prognostic sign. Although ulcerated lesions tended to be considerably thicker than non-ulcerated lesions, this factor did not entirely explain the poor prognosis recorded for patients with ulcerated lesions. In men and women matched by the thickness of their tumours, prognosis for those with ulcerated lesions was worse than for those with non-ulcerated lesions. This effect was particularly marked in women. It was concluded that since this histological feature was an independent prognostic determinant, it should be reported by the pathologist as a guide to the clinician in assessing prognosis in patients with melanoma.

Computer-detected ventricular tachycardia in the coronary care unit: prognosis in patients with and without acute myocardial infarction.

Survival (for up to 6 years) in coronary care unit (CCU) patients with ventricular tachycardia (VT) was studied with the aid of an automated arrhythmia monitoring system. Ventricular tachycardia was defined as four or more consecutive ventricular beats with a rate above 120 per min. During an 18-month period. VT was observed in 102 individuals (13%) out of 800 patients without acute myocardial infarction (AMI). The 102 patients were compared with age- and sex-matched patients with AMI and VT and a group with AMI but without VT. Hospital mortality was 27% in patients with AMI and VT, 23% in patients with AMI without VT, and 16% in non-AMI patients with VT (NS). First year mortality after discharge was 20% in the non-AMI group compared to 12% in the AMI groups (NS). The 1-6 years survival curves also did not differ significantly between the groups with a yearly mortality of between 5 and 6%. Acute myocardial infarction patients with rapid VT (greater than 150 min-1) or long VT (more than 10 beats) had a higher hospital mortality, otherwise the number or type of VT episodes did not relate to short- or long-term prognosis in the studied groups. Ventricular tachycardia in the CCU did not seem to be an indicator of poor long-term prognosis. It is concluded that long-term prognosis in patients with VT in the CCU was little influenced by a current diagnosis of AMI.

Estimation of prognosis and prevalence of retinitis pigmentosa and Usher syndrome in Norway.

Retinitis pigmentosa was diagnosed in 101 persons from 53 families. The prognosis for visual function was most favourable for the autosomal dominant group (38 patients from 8 families). The autosomal recessive group (40 patients from 25 families) and the 19 solitary cases were very heterogeneous, with prognosis ranging from favourable to very bad. There was a higher intrafamiliar correlation in the autosomal recessive than in the autosomal dominant group. In 28 patients from 18 families with Usher syndrome, almost all had good visual function until 30 years of age, and few had useful visual function after the age of 50. The age when the patients were registered varied between the different genetic types of retinitis pigmentosa, reflecting differences in prognosis. Therefore, ascertainment probability and prevalence were calculated for each genetic group separately. The prevalence of retinitis pigmentosa in Norway, all genetic groups included, was calculated to be 1/4440, the autosomal dominant type of the disease being the most frequent. The prevalence of Usher syndrome was calculated to be 3.6/100,000. Both retinitis pigmentosa and Usher syndrome were more prevalent in Laps.

Prognosis after cardiac arrest occurring outside intensive care and coronary units.

Emergency calls to a total of 1686 patients with verified cardiac arrest in the University Hospital, Arhus, were made in the 8-year period 1969-1977. Among the patients, cardiac arrest occurred outside the hospital in 1347, in the general wards in 240, while it was present on arrival at the emergency room in 99. Resuscitation was attempted in 1172 patients; 181 survived for at least 24 hours, and 72 were discharged alive, including 13 with residual brain damage. The prognosis was best when cardiac arrest occurred in the general wards (13% discharged) and poorest when it occurred outside the hospital (4% discharged). However, in the latter group, the prognosis showed considerable improvement when resuscitation was initiated at once by a doctor or by laymen present at the accident site (16% discharged). As regards the mechanism of cardiac arrest, ventricular fibrillation was found to be a relatively favourable prognostic sign (10% discharged), whereas almost none of the patients with asystole or severe bradycardia survived. The possibility of improving the prognosis of cardiac arrest occurring outside hospital by the establishment of mobile coronary care units and by instructing lay people in the technique of cardiopulmonary resuscitation is discussed.

Value of computed tomography-derived estimated liver volume/standard liver volume ratio for predicting the prognosis of adult fulminant hepatic failure in Japan.

BACKGROUND AND AIMS: The prognosis of fulminant hepatic failure (FHF) has been improved but is still unsatisfactory, and liver atrophy has been reported as a poor prognostic factor for this disease. The aim of this study was to assess the clinical value of the estimated liver volume (ELV) compared to the standard liver volume (SLV) in patients with FHF. METHODS: Estimated liver volume of 24 adult patients with FHF receiving artificial liver support (ALS) was measured by using computed tomography. Actual liver weight (ALW) was measured if possible, and the calculated ELV/SLV ratio was compared to the ALW/SLV ratio and the ALW/BW (bodyweight) ratio. Sequential ELV/SLV ratios during the clinical course were analyzed in relation to the prognosis. RESULTS: The ELV/SLV ratio was significantly correlated with both the ALW/SLV and ALW/BW ratios. The mean ALW/SLV ratio of patients who underwent living donor liver transplantation (LDLT) was 0.59 +/- 0.17. The mean ELV/SLV ratio at the time of starting ALS (day 0) in the patients who survived (group 1) was 1.081 +/- 0.183, but that of cases who underwent LDLT or died without LDLT (group 2) was 0.764 +/- 0.255. The mean ELV/SLV ratios were 1.084 +/- 0.222 and 0.650 +/- 0.195 in groups 1 and 2, respectively, 5 days after starting ALS (day 5). Among the group 2 patients, those who had no liver atrophy on day 0 had a significantly decreased ELV/SLV ratio on day 5. CONCLUSIONS: These results suggest that the ELV/SLV ratio is a very useful objective marker to estimate liver atrophy and this marker reflects the prognosis of FHF patients very well.
