Prognosis of patients with nonmalignant chronic intestinal failure receiving long-term home parenteral nutrition.

BACKGROUND/AIMS: Long-term survival of patients with intestinal failure requiring home parenteral nutrition (HPN) has been only partly shown. Therefore, we described the survival of these patients and explored prognosis factors. METHODS: Two hundred seventeen noncancer non-acquired immunodeficiency syndrome adult patients presenting with chronic intestinal failure enrolled from January 1980 to December 1989 in approved HPN programs in Belgium and France; prognosis factors of survival were explored using multivariate analysis. Data were updated in March 1991; not one of the patients was lost to follow-up. RESULTS: Seventy-three patients died during the survey, and the mortality rate related to HPN complications accounted for 11% of deaths. Probabilities of survival at 1, 3, and 5 years were 91%, 70%, and 62%, respectively. Three independent variables were associated with a decreased risk of death: age of patients younger than 40 years, start of HPN after 1987, and absence of chronic intestinal obstruction. In patients younger than 60 years of age included after 1983 with a very short bowel, who could represent suitable candidates for small bowel transplantation, the 2-year survival rate was 90%, a prognosis that compared favorably with recent reports of survival after small bowel transplantation. CONCLUSIONS: HPN prognosis compares favorably with recent reports of survival after small bowel transplantation.

Prognostic value of cerebral blood flow autoregulation in the long-term prognosis of ischemic cerebrovascular disease.

The correlation between long-term prognosis, cerebral blood flow (CBF) and CBF autoregulation was studied in 34 patients with cerebral infarction (mean age, 64 years). CBF was measured by the nitrous oxide method 1-6 months (mean 87 days) after disease onset. CBF autoregulation was evaluated quantitatively from the Dysautoregulation Index (DI) (delta CBF/delta effective MABP). Reductions in effective MABP were induced with a tilt table. No significant correlation was noted among CBF, DI and activities of daily living at the time of measurement. The patients' physical condition was reevaluated by questionnaire 2 years or more (mean 32 months) later. Better functional state at follow-up was related to higher CBF and lower DI values although the differences were not significant. The relationships among CBF, DI and changes in physical condition during the period were evaluated. The mean CBF values in patients with a better prognosis exceeded those of poor prognosis patients. The CBF values in the group who became independent significantly exceeded those in the group that deteriorated (P less than 0.05). The CBF values in the latter showed small but significant decreases during head-up tilting (P less than 0.05). The DI in this group was significantly higher than in the groups with a less severe outcome (P less than 0.01, P less than 0.05, respectively). In conclusion, determinations of CBF autoregulation, together with flow values, in the chronic state may have some value in predicting the long-term prognosis in cerebral infarction.

Age and prognosis in stage Ib squamous cell carcinoma of the uterine cervix.

Two materials consisting of patients with early invasive squamous cell carcinoma of the uterine cervix have been studied in regard to the influence of age and treatment technique on prognosis. In the first material, consisting of 254 Stage Ib patients treated only with radiation therapy, a poorer prognosis was found in the women under 35 years of age. The second material consisted of 274 Stage Ib patients who had been preoperatively irradiated and had undergone radical hysterectomy. The prognosis was (not significantly) better for those patients under 35 years of age in this group. The rate of central recurrence was higher among the younger patients who received only radiation therapy. Analysis of histologic grading and cell type according to J. W. Reagan and S. F. Yao (Int. J. Radiat. Oncol. Biol. Phys. 5, 1015-1020 (1979) ) revealed no explanation for the poorer prognosis among younger women treated solely with radiation therapy.

The prognosis of contact dermatitis.

This article reviews the prognosis of contact dermatitis, particularly of occupational contact dermatitis. Most studies document a poor prognosis for occupational and nonoccupational contact dermatitis. The prognoses of occupational and nonoccupational contact dermatitis, irritant contact dermatitis, and allergic contact dermatitis are similar. Only a minority of studies on the prognosis of occupational contact dermatitis have found that a job change by the affected worker leads to clearing of the dermatitis. Dermatologic and nondermatologic factors associated with a poor prognosis are discussed.

Myocardial infarction in young adults: angiographic characterization, risk factors and prognosis (Coronary Artery Surgery Study Registry).

OBJECTIVES: This study examined the angiographic characteristics, coronary risk factors and prognosis in young men and women with a history of myocardial infarction compared with that in older patients. BACKGROUND: There are few data regarding myocardial infarction in young adults. It is undetermined whether the development of myocardial infarction at a young age represents a form of coronary heart disease with an adverse prognosis. METHODS: Of the 8,839 patients with a history of myocardial infarction in the Coronary Artery Surgery Study (CASS), there were 294 men < or = 35 years old and 210 women < or = 45 years old. Coronary anatomy, baseline characteristics and prognosis were compared in younger and older patients. RESULTS: Young men and women more often had angiographically normal coronary arteries, nonobstructive disease < 70% stenosis and single-vessel disease than older patients (p < 0.0001). Current smoking was more frequent in young patients (p < 0.0001). Hypertension and diabetes were more frequent in both older men and women, whereas a positive family history of premature coronary disease was significantly more prevalent only in young men. The survival rate at 7 years was improved for young men compared with that in older men (84% vs. 75%, p = 0.0094) and for young women compared with that in older women (90% vs. 77%, p = 0.0004). When multivariate analysis was applied to the data, the survival advantage for young patients remained after adjustment. CONCLUSIONS: Young patients with a myocardial infarction have a favorable prognosis compared with that in older patients.

Expression of E-cadherin, and CD44s and CD44v6 and its association with prognosis in head and neck cancer.

OBJECTIVES: In the current study, the expression of E-cadherin, CD44s, and CD44v6 has been noted as markers for tumor metastasis and prognosis in several tumors, so we examined whether or not E-cadherin, CD44s, and CD44v6 are useful markers for evaluating the prognosis of mesopharyngeal cancer patients. METHODS: The expression of E-cadherin, CD44s, and CD44v6, was evaluated immunohistochemically using monoclonal antibodies against epitopes of standard and variant proteins, in paraffin-embedded mesopharyngeal cancer tissues from 57 patients who had received curative therapy. RESULTS: Tumor tissues from 47 (82.5%) patients showed positive immunoreactivity with monoclonal antibody against E-cadherin, 43 (75.4%) patients showed positive expression with CD44, and 45 (78.9%) patients showed positive expression with CD44v6. The expression of CD44v6 was slightly correlated with tumor volume, and lymph node metastasis, and stage classification (P > 0.05). However, there was no significant correlation between the expression of E-cadherin, CD44s and CD44v6 and clinicopathological characteristics. Concerning the prognosis, the survival period of patients with CD44s positive tumors was shorter than that of patients with CD44s negative tumors (18.2% versus 52.1%, 5-year survival, P > 0.05). The survival period of patients with CD44v6 positive tumors was also shorter than that of patients with CD44v6 negative tumors (12.8% versus 55.6%, 5-year survival, P > 0.05). CONCLUSION: These results suggest that CD44v6 may be related to tumor invasion and metastasis, and both CD44s and CD44v6 may be useful markers for poor prognosis in head and neck cancer.

[Parent's information and prenatal diagnosis of cerebral malformation with an uncertain prognosis].

UNLABELLED: Fetal ultrasounds examinations allow identification of brain malformations; announce of diagnosis and information about prognosis may be difficult when malformation is rare and prognosis uncertain. OBJECTIVES: In this study we tried to analyze how fetal imaging for prenatal screening was organized and how couples were managed and supported. METHODS: We focused on the procedures used to inform couples: content, method of delivery and consequences. A referent physician in each large multidisciplinary center for prenatal diagnosis in Paris area was questioned by semi-directed interview. RESULTS: Our study showed that it is difficult to standardize the way in which information is supplied before and after fetal ultrasounds examination; uncertainty about prognosis led more often to abortion. CONCLUSION: Thus, couples should have clear and complete information provided by a multidisciplinary team including specialists particularly concerned by the malformation (neuropediatrician and/or neurosurgeon)--moreover when prognosis is uncertain, in order to support them, and to accompany their decision concerning pregnancy.

Influence of MRI abnormality in skull base bone on prognosis of nasopharyngeal carcinoma.

PURPOSE: To evaluate the influence of skull base bone (SBB) abnormality showed by MRI on prognosis of nasopharyngeal carcinoma (NPC). PATIENTS AND METHODS: From March 1993 to December 1998, 122 NPC patients received prime radiotherapy treatment. All of them were proved pathologically and checked by magnetic resonance imaging (MRI). Every patient received radiation through conjoint facio-cervical field and conventional dose-fractionation schedules. The total dose to the primary tumor was 60-75 Gy (median, 70 Gy). The Kaplan-Meier method, the Log-rank test and the Cox regression model were used to evaluate the significance of prognostic factors on NPC patient survival. RESULTS: The overall median survival period was 50 (6-92) months, and the 1, 3 and 5 year-survival rates were, respectively, 99.2%, 87.9%, and 73.3%. The 1, 3, and 5 year-survival rates of abnormality and normality of the SBB on MRI were 98.9%, 87.2%, 71.9%, and 100.0%, 89.8%, 77.0%, respectively (P = 0.4233). Gender, age, head pain, SBB abnormality, cranial nerve palsy, cervical lymphadenopathy and primary tumor extent were analyzed with the Cox regression model and SBB abnormality on MRI did not prove to have statistical significance (P = 0.6934). According to the analysis of regrouping, patients with SBB abnormalities > or =2 sites have a worse prognosis (P = 0.0427). Then, the above seven factors are analyzed by Cox regression model and the result had statistical significance (P = 0.0385). CONCLUSION: The SBB abnormality on MRI is of no obvious influence on prognosis of NPC. However, when SBB abnormality sites were > or =2, there is obvious statistical significance on the prognosis.

The management of poor-prognosis, non-seminomatous germ-cell tumours.

Despite a high cure rate in men with testicular cancer, some men in the poor-prognosis group have a less favourable outcome. Poor-prognosis non-seminomatous germ-cell tumours (NSGCT) are defined as those with high tumour markers, non-pulmonary visceral metastases or a mediastinal primary site at presentation. When treated with standard chemotherapy regimens, such as bleomycin, etoposide and cisplatin (BEP), cure rates of less than 50% have been achieved in an international pooled analysis. Some strategies aimed at improving results include the use of multi-agent regimens (e.g. POMB/ACE), intensive-induction chemotherapy (e.g. CBOP/BEP), new chemotherapy drugs, such as ifosfamide, gemcitabine, oxaliplatin, paclitaxel, high-dose chemotherapy, including autotransplantation. To date, no schedule has been proven to be better than standard BEP in randomised trials. We will review the published data relating to first-line and salvage treatment of poor-prognosis NSGCT. To advance the management of this disease, physicians treating poor-prognosis disease are urged to support multi-centre trials, such as the recently launched MRC TE23 study comparing BEP and CBOP/BEP.

Expression of heat-shock protein Hsp60 correlated with the apoptotic index and patient prognosis in human oesophageal squamous cell carcinoma.

Cellular stress response and apoptosis are two highly conserved mechanisms for maintaining homeostasis. Hsp60 and Hsp90 have been shown to play pro- and anti-apoptotic roles, respectively. Our present study examined whether there is a correlation between the expression of Hsp60 and Hsp90, clinical parameters, the apoptotic index (AI), and the prognosis of patients with oesophageal squamous cell carcinoma (ESCC). We immunohistochemically stained cells for Hsp60, Hsp90, and single-stranded DNA (ssDNA), which acts as an apoptotic marker. In normal oesophageal epithelium tissue, Hsp60 and Hsp90 were expressed in the cytoplasm and membrane from the basal cell layer to the supra-basal cell layers. Hsp60 and Hsp90 positive stainings (+) were found in 63 of 123 cases (51%) and 62 of 123 cases (50%), respectively. There was no correlation between Hsp60 and Hsp90 expression levels and any of the clinical parameters examined. The five-year survival rate for ESCC patients with Hsp60 (+) expression was significantly higher than for those patients with Hsp60 (-) expression (P=0.0371). Five-year survival rates of patients with Hsp60 (+) and (-) were 49% and 33%, respectively. By contrast, Hsp90 expression failed to predict patient prognosis (P=0.7965). The high-AI group did not have a significantly better prognosis than the low-AI group (P=0.2218). Statistical analysis showed a significant correlation between the expression of Hsp60 and AI in ESCC patients (P=0.008). Thus, the five-year survival rate for the high-AI/Hsp60 (+) group was statistically significantly better than for the other groups (P=0.0281). The results obtained in this study indicate that positive Hsp60 expression is a good prognostic indicator. This may be due to its role as a chaperone in contributing to the induction of apoptosis. These data suggest that Hsp60 expression correlates with the AI and patient prognosis in human ESCC.

Prognosis of muscle-invasive bladder cancer: difference between primary and progressive tumours and implications for therapy.

OBJECTIVE: To evaluate the difference in prognosis between progressive and primary muscle-invasive bladder cancer. MATERIALS AND METHODS: From 1986 to 2000, 74 patients with progressive muscle-invasive bladder cancer were identified. Eighty-nine patients with primary muscle-invasive bladder cancer were frequency matched for stage to these patients with progressive disease. Baseline data including patient and tumour characteristics were collected at the time of diagnosis of the muscle-invasive tumour. Duration of survival was defined as time from muscle-invasive bladder cancer diagnosis until disease-specific death. Kaplan-Meier curves were drawn to determine the difference in prognosis between the two study groups. To adjust for potential residual confounding due to differences in treatment, 4 subgroups (T2/3, T4, N+ and M+) were constructed according to the TNM classification. In order to see whether age and gender had any effect on outcome, the four stage groups, age and gender were entered in a Cox's proportional hazard regression model. RESULTS: The 3-year bladder cancer-specific survival was 67% in the primary group and 37% in the progressive group (log rank p=0.0015). Kaplan-Meier curves comparing the different stage groups showed a better prognosis for the patients with primary, i.e. pT2/3 or N+, tumours at baseline. Cox regression analysis demonstrated that age and gender had no influence on bladder cancer-specific survival. CONCLUSIONS: Patients with muscle-invasive bladder cancer and a history of superficial bladder cancer have a worse prognosis than patients with primary muscle-invasive bladder cancer.

Combined right ventricular systolic and diastolic dysfunction represents a strong determinant of poor prognosis in patients with symptomatic heart failure.

BACKGROUND: The presence of right ventricular systolic dysfunction is known to significantly worsen prognosis of patients with heart failure. However, the prognostic impact of right ventricular diastolic dysfunction and of its combination with right ventricular systolic dysfunction and with other prognostic markers has not yet been systematically studied. The aim of this study was to assess the prognostic impact of combined right ventricular systolic and diastolic dysfunction in patients with symptomatic heart failure due to ischemic or idiopathic dilated cardiomyopathy. METHODS: The study included 177 consecutive patients with symptomatic heart failure (mean left ventricular ejection fraction of 23%). All patients underwent clinical and laboratory examination, standard echocardiography completed by Doppler tissue imaging of the tricuspid annular motion, and right-sided heart catheterization. They were followed up for a mean period of 16 months (range, 1-48 months). RESULTS: During the follow-up, there were 28 cardiac-related deaths and 35 non-fatal cardiac events (31 hospitalizations for heart failure decompensation and 4 hospitalizations for malignant arrhythmias requiring the implantation of a cardioverter-defibrillator). The multivariate stepwise Cox regression modeling revealed the right ventricular systolic (represented by the peak systolic tricuspid annular velocity-Sa) and diastolic (represented by the peak early diastolic tricuspid annular velocity-Ea) function to be the independent predictors of event-free survival or survival (p<0.01). The Sa separated better between patients with and without the risk of cardiac events (p<0.05), while the Ea appeared to further distinguish patients with increased risk (those at risk of late event from those at risk of early non-fatal event and early death). The strongest predictive information was obtained by the combination of Sa and Ea creating the Sa/Ea categories. The Sa/Ea I category of patients (Sa>or=10.8 cm s(-1) and Ea>or=8.9 cm s(-1)) had excellent prognosis. On the other hand, the Sa/Ea IV category (Sa<10.8 cm s(-1) and Ea<8.9 cm s(-1)) was found to be at a very high risk of cardiac events (p<0.001 vs. Sa/Ea I). Imbalanced categories of patients (Sa/Ea II and III) with only one component (Sa or Ea) pathologically decreased were at medium risk when assessing event-free survival. However, a significantly better survival (p<0.05) was found in patients with Ea>or=8.9 cm s(-1) (Sa/Ea I and III categories) as compared with those having Ea<8.9 cm s(-1) (Sa/Ea II and IV categories). Thus, in contrast to event-free survival, the survival pattern was determined mainly by the Ea value with only little additional contribution of Sa. CONCLUSIONS: The assessment of right ventricular systolic and diastolic function provides complementary information with a very high power to stratify prognosis of patients with heart failure. The combination of right ventricular systolic and diastolic dysfunction identifies those with a very poor prognosis.

Abnormal uterine bleeding and prognosis of endometrial cancer.

OBJECTIVES: The aim of this study was to analyze the relationship between the period of abnormal uterine bleeding (AUB) and the prognosis of endometrial cancer. METHODS: We reviewed 304 endometrial cancer patients who were diagnosed and treated between 1985 and 1998 in our hospital, and whose history of AUB and clinical parameters were clearly available from their charts. Pathological data and overall survival were compared between groups having different periods of AUB. RESULTS: Duration of AUB had no impact on the prognosis of endometrial cancer. Patients diagnosed with endometrial cancer without AUB showed a significantly better 5-year overall survival rate than the patients diagnosed after the onset of AUB. The distribution of clinical stages and histological grades did not differ depending on AUB status. CONCLUSIONS: The prognosis of endometrial cancer was determined by the histopathological character of the tumor. However, the diagnosis and treatment of endometrial cancer with some suspicious signs other than AUB might improve the prognosis.

Plasma leptin and prognosis in patients with established coronary atherosclerosis.

OBJECTIVES: This study was designed to evaluate the relationship between plasma leptin and prognosis in patients with angiographically confirmed coronary atherosclerosis. BACKGROUND: Experimental studies suggest that leptin, an adipose tissue-derived hormone, exerts important cardiovascular effects. METHODS: Study subjects were recruited prospectively from a cohort of patients undergoing clinically indicated coronary angiography (n = 382). The median duration of follow-up was four years. Follow-up information was available for 361 patients. RESULTS: The combined end point of cardiac death, myocardial infarction (MI), cerebrovascular accident, or re-vascularization occurred in 44 subjects. In the simple Cox model, leptin had a significant (p < 0.001) non-linear/cubic univariate relationship with the combined end point. Other variables associated with prognosis in the univariate analysis were body mass index (BMI), prior MI, insulin resistance, C-reactive protein (CRP), fibrinogen, and number of coronary vessels with >50% stenosis. A positive relationship between leptin and prognosis was also seen when leptin levels were split by quintiles, with a hazard ratio of 6.46 for the highest quintile. The only two variables significantly associated with the combined end point in the multivariate Cox model were leptin (p = 0.004) and number of coronary vessels with >50% stenosis (p < 0.001). A similar relationship between leptin and prognosis was observed when leptin was adjusted for BMI. CONCLUSIONS: In patients with angiographically confirmed coronary atherosclerosis, leptin is a novel predictor of future cardiovascular events independent of other risk factors, including lipid status and CRP.

Prognosis research: why is Dr. Lydgate still waiting?

BACKGROUND: Understanding prognosis--the future risk of adverse outcomes among people with existing disease--plays third fiddle behind clinical research into therapeutic interventions and novel diagnostic technologies. METHODS AND RESULTS: Diseases show marked variations in a wide range of prognostic outcomes, yet these variations have seldom been the subject of systematic and sustained epidemiologic and multidisciplinary research. This is important to prioritize hypotheses for testing in intervention studies in groups, and to refine tools for prognostication in individuals. Methodologic standards for the design, conduct, analysis and reporting of prognosis research are required. Training is needed for the clinicians, policymakers, and payers who use prognostic information. CONCLUSION: Here, arguments detracting from the potential scope of prognosis research are rebutted and misconceptions addressed with the aim of stimulating debate on the evolving role of prognosis research.

Decreased impact of post-myocardial infarction depression on cardiac prognosis?

OBJECTIVE: A recent meta-analysis suggests that the impact of post-myocardial infarction (MI) depression on cardiac prognosis has decreased over the last decade. We tested whether depression still significantly affects prognosis in the present health care situation. METHODS: Four hundred ninety-four MI patients were screened for depression. Patients with depression were compared with patients without on cardiovascular events (fatal or nonfatal) during an average follow-up of 2.5 years. Demographic characteristics and cardiac risk factors were controlled for. RESULTS: We found that depression was associated with the occurrence of cardiovascular events in both univariate [hazard ratio (HR), 1.84; 95% confidence interval, 1.24-2.72] and multivariate analysis (HR, 1.56; 1.02-2.38). CONCLUSIONS: Depression still has an independent impact on cardiac prognosis after MI, but this influence is smaller than found in early studies. Improvements in general care for MI and better recognition and treatment of post-MI depression may have decreased the impact of depression on prognosis.

Methylation of p15(INK4b) and E-cadherin genes is independently correlated with poor prognosis in acute myeloid leukemia.

Hypermethylation of CpG islands is a common mechanism by which tumor suppressor genes are inactivated. The tumor suppressor gene p15(INK4b) is important component of cell cycles, whereas E-cadherin gene is often termed a metastasis suppressor gene. We have studied the feasibility of detecting tumor-associated aberrant p15(INK4b) and E-cadherin methylation in acute myeloid leukemia (AML) using methylation-specific PCR. Aberrant methylation of p15(INK4b) was detected in 31 of 61 (51%) AML patients. On the other hand, E-cadherin hypermethylation was detected in 36 of 61 (56%) AML patients. We have examined the methylation pattern of these genes and the prognosis in AML patients using a log-rank test. Methylation of p15(INK4b) gene significantly correlated with prognosis (p=0.0012), and methylation of E-cadherin gene more significantly correlated with prognosis (p=0.0004). When both were methylated, there was even more significant unfavorable prognosis compared to either of the methylated genes (p<0.0001). We interpret these data to mean that dysfunction of the cell cycle and/or the cell-cell adhesion molecule plays a role in the pathogenesis of acute myeloid leukemia and that analysis of the methylation of p15(INK4b) and E-cadherin genes can provide clinically important evidence on which to base treatment.

Effect of leukocytosis at initial examination on prognosis in patients with primary unstable angina.

BACKGROUND: Leukocytosis with acute myocardial infarction at initial examination predicts adverse prognosis, but it is unknown whether it predicts outcome in patients with primary unstable angina. METHODS AND RESULTS: We studied 414 consecutive patients with unstable angina admitted through the emergency department to telemetry and intensive care units of an urban academic hospital. To study primary unstable angina, we excluded 134 patients with precipitants (eg, urosepsis, pneumonia) that may cause leukocytosis. Of 280 patients, 96 (34%) had leukocytosis (leukocyte count >10,000 per microL) at initial examination. A total of 30 patients (11%) died and 47 (17%) died or had nonfatal myocardial infarction within 12 months of initial examination. In a univariate Cox model, patients with leukocytosis had a hazard ratio (HR) of 2.6 (95% confidence interval [CI] 1.3-5.4) for death by 1 year. In a multivariate Cox model the only significant predictors of 1-year death were congestive heart failure at initial examination (HR 7.8; 95% CI 2.8-22) and elevated creatinine (HR 2.7; 95% CI 1.3-5.7); in this model, the relation between leukocytosis and prognosis was markedly attenuated (HR 1.4; 95% CI 0.6-2.9). The adjusted HR for leukocytosis was 1.3 (95% CI 0. 7-2.3) for death or nonfatal MI by 1 year. CONCLUSIONS: Leukocytosis at initial examination is associated with adverse prognosis in patients with primary unstable angina. However, the association is confounded by other important predictors of prognosis. Leukocytosis may be a marker of stress associated with more severe cases of unstable angina or comorbid conditions.
