[Prognostic indications within the scope of the selection of cochlear implant patients].

The common selection criteria for cochlear implant patients do not allow any prognostic indication on the final result. On the other hand, some postoperative data (threshold, TDL, dynamic range, duration of deafness) corresponds clearly with the results, some of them also correspond with the preoperative data. Preoperative TDL, dynamic range as well as duration of deafness can therefore be used as suitable prognostic indicators.

Prognostic indicators in femoropopliteal reconstructions.

The incidence of early failure in 115 vein femoropopliteal grafts has been analyzed for the presence of reliable prognostic indicators of such failures. One hundred twelve patients had preoperative Doppler ultrasound assessment; 98 had intraoperative graft flow measured. Early graft failure was more prevalent in patients with rest pain and gangrene and in patients with poor runoff. Neither of these two findings had predictive value. Ninety-one percent of patients with a pressure index (ankle systolic pressure/brachial systolic pressure) less than 0.20 had early graft thrombosis. This suggests that arterial reconstruction is futile in this group. Measurement of vein graft flows intraoperatively was of value. Grafts with basal flows less than 70 ml/min uniformly thrombosed. There was significant correlation between ankle pressure index and intraoperative vein graft flow (r=.52). Both ankle pressure index and intraoperative vein graft flow provide prognostic indications of graft failure and should be of value in selecting patients for femoropopliteal reconstructions.

Prognostic indicators for renal cell carcinoma: a multivariate analysis of 643 patients using the revised 1997 TNM staging criteria.

PURPOSE: We determine independent prognostic indicators for renal cell carcinoma using the revised 1997 TNM staging criteria. MATERIALS AND METHODS: The records of 643 consecutive patients undergoing partial or radical nephrectomy at our institution between 1987 and 1998 were reviewed. Preoperative evaluation of functional status using the Eastern Cooperative Oncology Group (ECOG) criteria was performed in all cases. Renal cell carcinoma grade and stage were evaluated using the 1997 American Joint Committee on Cancer grading and TNM staging criteria, respectively. Patients were followed for a mean plus or minus standard deviation of 47+/-40 months (median 87). Kaplan-Meier survival curves were used to determine 5-year cancer specific survival for all patient groups. Univariate analysis using log rank sum tests was performed to evaluate the prognostic significance of overall TNM stage, tumor stage, disease grade and ECOG status. Multivariate analysis was performed to determine which factors had an independent impact on survival of patients with renal cell carcinoma. RESULTS: The 5-year cancer specific survival rate was 91%, 74%, 67% and 32% for TNM stages I, II, III and IV lesions, respectively (p<0.001). Analysis demonstrated a survival rate of 83% for stage T1, 57% for stage T2, 42% for stage T3 and 28% for stage T4 disease (p<0.001), and 89% for grade 1, 65% for grade 2, and 46% for grades 3 and 4 (p<0.001). Multivariate analysis revealed that overall TNM stage and grade of disease were the most important prognostic indicators for renal cell carcinoma (p<0.001). ECOG classification was a less significant predictor (p = 0.031) and tumor stage was not shown to have any independent impact on patient survival (p = 0.138). CONCLUSIONS: Better survival rates of patients with localized and advanced renal cell carcinoma can be demonstrated with recent advances in diagnosis and treatment. The revised 1997 TNM criteria manifest an appropriate adjustment in staging renal cell carcinoma based on these improvements, with overall stage correlating with cancer specific survival. In contrast, while effectively predicting survival, tumor stage did not demonstrate an independent impact on renal cell carcinoma prognosis under multivariate analysis. Instead, other factors, such as ECOG status and more importantly grade of disease, appeared to affect survival significantly as independent elements. Based on our recent experience with patients treated for renal cell carcinoma in the era of enhanced technology and improved survival, tumor grade and molecular markers may serve as useful adjuncts to TNM staging in guiding treatment and predicting survival outcomes.

Response of the microtubular cytoskeleton following hyperthermia as a prognostic indicator of survival of Chinese hamster ovary cells.

PURPOSE: The response of the microtubular (MT) cytoskeleton to hyperthermia was assessed as a prognostic indicator of cytotoxicity. METHODS AND MATERIALS: Heat-induced collapse and subsequent recovery of the MT system were compared with survival for both nonthermotolerant (NT) and thermotolerant (TT) G1 populations of Chinese hamster ovary (CHO) cells. The response of the MT system was monitored using immunofluorescence staining. The G1 populations of NT and TT cells were heated by submersion in 45.0 and 43.0 degrees C waterbaths. RESULTS: Heat-induced perinuclear collapse of the MT system did not correlate with survival for the NT and TT populations. However, recovery of the organization of the MT cytoskeleton was correlatable with survival. The regression line of survival plotted as a function of MT recovery is fit by: y = -0.43 + 1.03x, r2 = 0.95 (p < 0.0005). CONCLUSION: Restoration of the organization of the MT cytoskeleton following hyperthermia may be used as a prognostic indicator of survival of CHO cells heated in G1.

Prognostic indicators in haemolytic uraemic syndrome.

OBJECTIVE: This study aims to review the clinical presentations of Haemolytic Uraemic Syndrome (HUS) and to compare the poor prognostic indicators with mortality. METHODS AND MATERIALS: Prospective study carried out in Renal Dialysis ward of Dhaka Shishu Hospital, Bangladesh from September 2001 November 2003 for a period of 26 months. All children admitted to renal dialysis ward with oliguria or anuria with pallor was included in this study. HUS was confirmed after laboratory investigations showing features of hemolytic anaemia, thrombocytopenia and renal insufficiency. Various clinical presentations were reviewed. Then bad prognostic factors were compared with mortality. RESULTS: There were total 25 cases of HUS in 26 months.17 (68%) were males and 8(32%) females.21 (84%) children were < 5 years. Only 4(16%) were > 5 years. Before onset of HUS 40% children had bloody diarrhoea, 36% had acute watery diarrhoea and 24% had others symptoms. The other presentations noted were fever 88%, respiratory distress and convulsion 52% and oliguria 40%, anuria 60%, reluctant to feed 40% and cough 28%. The main physical findings noted were irritability 40%, pallor 100%, dehydration 28%, puffy face with oedema 32%, high blood pressure 16%, hepatomegaly 28%, jaundice, sclerema and petechial rashes 8%, lethargic 16%, acidotic breathing 48% and rectal prolapse 12%. 44% children died after HUS and 56% recovered from the illness. Mortality was 66% when duration of illness before onset of HUS was > 14 days. With duration of anuria < 3 days there was no mortality but it was 91% and 100% with anuria > 3 to 8 days and >8 days respectively. Mortality was 78% when age was < 18 months and it was 75% when age was > 5 years. Diarrhoea associated HUS had 27% and non diarrhoea associated HUS had 85% mortality. Mortality was 77% and 100% respectively when HUS was associated with convulsion and hypertension. WBC > 30,000 had mortality 100% and decreased platelet count < 30,000 had mortality 80%. With creatinine level > 700 micromol/L mortality was 80% and with Serum potassium level 5.6 to 7.5 mmol/L mortality was 67%. CONCLUSION: HUS comprised of varieties of presentations. Diarrhoea was the commonest preceding illness before onset of HUS. The bad prognostic indicators carrying high mortality was duration of illness before onset of HUS >14 days, anuria > 3 days, age < 18 months and >5 years, Non diarrhoea associated HUS, HUS associated with convulsion and hypertension, WBC > 30,000/cumm, platelets < 30,000/cumm, creatinine level > 700 micromol/L and serum potassium level 5.6 to 7.5 mmol/L. Since bad prognostic factors may progress rapidly to mortality, consultation with paediatrician and transfer to a tertiary care centre should be done when HUS is diagnosed so that it can be managed appropriately in time.

Bacteremia in patients with hematological malignancies. Analysis of risk factors, etiological agents and prognostic indicators.

BACKGROUND AND OBJECTIVE: Patients with hematological malignancies are at increased risk for developing bacteremia. No previous study has investigated the risk and prognostic indicators of bacteremia in such patients using a statistical approach. METHODS: A case-control study was performed in 106 patients with hematological malignancies (group A). Two hundred and twelve patients were included as controls and divided into two groups: 106 patients with hematological malignancy without bacteremia (group B) and 106 HIV-infected patients with bacteremia (group C). RESULTS: At univariate analysis, bacteremia risk factors in group A were: neutropenia for more than six days (p = 0.03 vs. group B), central venous catheter usage (p = 0.04) and absence of antibiotic prophylaxis (p = 0.03). At multivariate analysis, the use of CVC and neutropenia were independent bacteremia risk factors. The most frequent etiological agents were: Staphylococcus epidermidis and Pseudomonas aeruginosa. Comparing groups A and C, the distribution of Staphylococcus spp. was different, with S. epidermidis being prevalent in hematological patients only. As regards gram-negative organisms, it is of note that no episode of NT-Salmonella bacteremia was observed in group A, unlike group C, where they represent the second leading etiological agents. In group A, 14% of the patients died. Persistent neutropenia (p = 0.01) and the presence of relapsed neoplasm (p = 0.04) were prognostic indicators of bacteremia. INTERPRETATION AND CONCLUSIONS: Our findings suggest that bacteremia in patients with hematological malignancies strictly correlates with the intensity and length of neutropenia and CVC usage. Although we observed a low mortality rate, we stress that this clinical condition requires special attention from the physician, who must recognize and treat it promptly.

Low first postoperative day intraocular pressure as a positive prognostic indicator in deep sclerectomy.

AIM: To study the possibility of using intraocular pressure (IOP) in the first postoperative day after sclerectomy as a prognostic indicator. METHODS: Non-randomised prospective trial involving 105 eyes of 105 patients with medically uncontrolled primary and secondary open angle glaucoma. Visual acuity, IOP, and slit lamp examinations were performed before and after surgery at 1 and 7 days, and 1, 3, 6, 9, 12, 18, 24, 30, 36, 48, 54, 60, and 66 months. Visual field examinations were repeated every 6 months. A split point on day 1 IOP of less than or equal to 5 mm Hg (61%) versus more than 5 mm Hg (39%) was used. The first postoperative day IOP was examined in relation to the need for subsequent Nd:YAG goniopuncture, the subsequent use of postoperative antiglaucoma medications, and as a stratification variable in the Kaplan-Meier analyses. RESULTS: The mean follow up was 43.2 (SD 14.3) months. The mean preoperative IOP was 26.8 (SD 7.7) mm Hg; the mean postoperative IOP was 5.1 (3.3) mm Hg at day 1 and 11.8 (3.1) mm Hg at month 60. Patients with IOP </=5 mm Hg had significantly fewer Nd:YAG goniopunctures (p = 0.0478). A significant (log rank test 0.0122) improvement for those with IOP </=5 mm Hg in terms of survival was detected using the most stringent criterion (IOP </=15 mm Hg with no medications). For patients with first postoperative day IOP </=5 mm Hg, the median time to failure was 24 months (95% CI: 12 to 30), but for those with an IOP >5 mm Hg, the median time to failure was only 6 months (CI 2 to 9). No significant difference in postoperative antiglaucoma medications was observed. CONCLUSION: First postoperative day IOP can be considered to be a significant prognostic indicator in deep sclerectomy.

Vascular density as a prognostic indicator for invasive ductal breast carcinoma.

Estimated vascular density obtained with the aid of antibodies against endothelial cells has been claimed to be an independent prognostic indicator for invasive ductal breast carcinoma. Since 1991 most studies have counted the number of vessels with the optic microscope. We have performed immunohistochemical staining for Factor VIII on formaldehyde-fixed, paraffin-embedded primary invasive ductal carcinomas from 112 patients, with a minimal follow-up time of 60 months, who had received postoperative chemoradiation therapy. We have performed a manual count with a 20x objective of the vessels in the vascular hot-spot identified in a 4x field. We analysed the association of this factor with epidemiological risk factors, histopathological features, hormonal receptor status and p53 and c-erbB-2 expression and the influence on prognosis. In univariate analysis vascular density is a significant prognostic indicator in both node-negative and node-positive patients, together with staging, Baak's morphometric multiparametric index, tumour size and histological grade. However, in multivariate analysis only tumour staging and vascular density are independent prognostic factors in breast carcinoma.

Blood lactate as prognostic indicator of survival in patients with acute myocardial infarction.

Serial measurements of arterial blood lactate were compared with established hemodynamic, respiratory, and metabolic measurements as prognostic indicators of survival or fatality in 28 patients with acute myocardial infarction complicated by heart failure and/or cardiogenic shock. Measurements were compared at the time of admission, at the time of maximal response to therapy, and 4 h prior to discharge or the onset of the agonal period. Blood lactate was the only measurement which consistently separated survivors from fatalities. The accumulation of lactate served as a sensitive and specific quantitative indicator of the severity of the oxygen dept and anaerobic metabolism. No patient survived in whom the arterial blood lactate was greater than 4 mmol/L for more than 12 h, regardless of the magnitude of the stroke volume, the left ventricular filling pressure, or the cardiac work. We regard the measurement of arterial blood lactate as a consistently useful prognostic indicator of survival or fatality in patients with acute myocardial infarction and myocardial failure.

Growth as a prognostic indicator in children with human immunodeficiency virus infection treated with zidovudine. AIDS Clinical Trials Group Protocol 043 Study Group.

OBJECTIVE: To assess measures of growth as prognostic indicators in response to zidovudine treatment in children with symptomatic human immunodeficiency virus infection. METHODS: We retrospectively assessed data from AIDS Clinical Trials Group Protocol 043, an open-label, phase II study of oral zidovudine therapy (180 mg/m2 per dose every 6 hours) in children with human immunodeficiency virus who have severe symptoms. Several variables were evaluated for their prognostic significance: CD4+ lymphocyte percentage; rates of weight gain and linear growth; entry weight, height, and weight-for-height z scores for age; race; gender; age; and route of transmission. RESULTS: The overall survival rate as of April 1, 1992 (4 years after study initiation), was 44%, with a median survival of 37.9 months. The risk of death was greatest in children with CD4+ lymphocyte percentages < 20% (relative risk, 3.49), but was also increased in children who had a weight-for-age z score < -2 on entry to the study (relative risk, 1.53) and in those who failed to gain weight at the 25th percentile rate or greater during the first 6 months of therapy (relative risk, 2.03). These three factors, as well as race and gender, were found to be significant predictors in a multivariate, proportional-hazards model of survival. Entry height-for-age and height growth rates did not have predictive value for survival in univariate or multivariate analyses. CONCLUSIONS: Weight-for-age and rate of weight gain are important, easily obtained, and inexpensive prognostic indicators in children with symptomatic human immunodeficiency virus treated with zidovudine. Both were less predictive of survival than the entry CD4+ lymphocyte percentage.

Prognostic indicators of early and late death in children admitted to district hospital in Kenya: cohort study.

OBJECTIVES: To identify clinical indicators of immediate, early, and late mortality in children at admission to a sub-Saharan district hospital and to develop prognostic scores. DESIGN: Prospective cohort study. SETTING: One district hospital in Kenya. PARTICIPANTS: Children aged over 90 days admitted to hospital from 1 July 1998 to 30 June 2001. MAIN OUTCOME MEASURES: Prognostic indicators of mortality. RESULTS: Of 8091 children admitted up to 1 June 2000, 436 (5%) died. Sixty (14%) died within four hours after admission (immediate), 193 (44%) after 4-48 hours (early), and 183 (42%) after 48 hours (late). There were marked differences in the clinical features associated with immediate, early, and late death. Seven indicators (neurological status, respiratory distress (subcostal indrawing or deep breathing), nutritional status (wasting or kwashiorkor), severe anaemia, jaundice, axillary temperature, and length of history) were included in simplified prognostic scores. Data from 4802 children admitted from 1 July 2000 to 30 June 2001 were used to validate the scores. For simplified prognostic scores the areas under the receiver operating characteristic curves were 0.93 (95% confidence interval 0.92 to 0.94), 0.82 (0.80 to 0.83), and 0.82 (0.81 to 0.84) for immediate, early, and late death, respectively. CONCLUSION: In children admitted to a sub-Saharan hospital, the prognostic indicators of early and late deaths differ but a small number of simple clinical signs predict outcome well.

Usefulness of four prognostic indices in differentiated thyroid cancer.

OBJECTIVE: To report the follow up of 82 patients with differentiated thyroid cancer in order to evaluate patients' clinical and tumor characteristics of prognostic value. PATIENTS AND METHODS: A prospective and comparative study was performed in 82 patients with differentiated thyroid cancer followed for a mean of 84 months. They were classified and included into four prognostic indices (pTNM, DeGroot's, AGES and NTCTCS) stages I and II were considered as a low risk ones and stages III and IV as a high risk group. At the end of the follow up period the patients were evaluated and divided into two groups, those with tumor activity (persistence or recurrence) and those in remission. A correlation coefficient and concordance analysis between the prognostic indices was done. Sensitivity, specificity and positive and negative predictive values were calculated in accordance with the tumor activity or the remission status. RESULTS: The highest correlation coefficient (r = 0.91, CI 0.85 to 0.94) was found between NTCTCS and pTNM indexes. The highest sensitivity (78%) and specificity (85.7%) was obtained with the NTCTCS index. CONCLUSION: In our population, NTCTCS index was a good option to evaluate the prognosis of patients with differentiated thyroid cancer.

Angiogenesis factor in endometrial carcinoma: a new prognostic indicator?

OBJECTIVE: Tumor angiogenesis is believed to be a prognostic indicator associated with tumor growth and metastasis. Studies of angiogenesis in breast, prostate, and lung cancer, as well as melanoma, have shown that neovascularization correlates with the likelihood of metastasis and recurrences. The purpose of this study was to evaluate microvessel density as a prognostic factor in endometrial cancer. METHODS: Between 1980 and 1991 the tumor registry identified 25 patients with a diagnosis of recurrent endometrial cancer. These patients were matched with 25 patients with nonrecurrent disease for age, stage, grade, and treatment. The histologic slides of the 50 patients were reviewed. The paraffin blocks were obtained, and the area of the deepest myometrial invasion was selected for staining. The microvessels within the invasive cancer were highlighted by means of immunocytochemical staining to detect factor VIII-related antigen. Microvessels were counted by two investigators who were blinded to the patients' clinical status. Survival data were analyzed with Kaplan-Meier survival curves. RESULTS: Microvessel count was related to likelihood of recurrence, although this trend did not reach statistical significance. Patients with tumors of low capillary density had a mean survival time of 123 months. Patients with tumors of high capillary density had a mean survival time of 75 months (p = 0.02). Among patients with recurrent disease, those with a low capillary count survived a mean of 64 months. Patients with recurrent disease with tumors of high capillary density survived a mean of 45 months (p = 0.002). CONCLUSION: Angiogenesis factor correlates with survival in endometrial carcinoma.

Morphologic and mucin histochemical analysis of transitional zones in advanced ulcerated colorectal carcinomas: potential prognostic indicators.

BACKGROUND AND OBJECTIVES: The transitional zone, which is normal-appearing mucosa that surrounds a primary colorectal carcinoma, has characteristic histologic features, and an increased amount of sialomucin in the transitional zone have been associated with a poorer prognosis. To clarify the prognostic effects of changes in the transitional zone we studied the transitional zone in cancers of the colon and rectum. METHODS: A total of 105 specimens resected for advanced colorectal carcinoma were studied to identify the effectiveness of evaluating morphologic types (polypoid or nonpolypoid growth type) and mucin expression (sulfomucin or sialomucin type) of the transitional zone as a prognostic indicator. RESULTS AND CONCLUSIONS: Nonpolypoid carcinomas were likely to have invaded the deeper layers and lymphatic vessels and go on to develop advanced disease. Sulfomucin-type tumors were predominantly found in the right side colon and followed a relatively favorable course. Our results indicate that the morphologic and mucin components of the transitional zone may be prognostic indicators for advanced colorectal carcinoma.

Assessment of corticosteroid-induced alkaline phosphatase as a prognostic indicator in canine lymphoma.

OBJECTIVES: To examine the incidence of elevated corticosteroid-induced alkaline phosphatase (sALP) in dogs with lymphoma and to determine if sALP is a reliable prognostic indicator in canine lymphoma. METHODS: The medical records of 62 canine lymphoma patients treated with a combination chemotherapy protocol from 1994 to 2003 at the University of Illinois Veterinary Teaching Hospital were examined. Variables assessed with respect to response rate and remission duration included age, bodyweight, sex, breed, World Health Organization stage (I to V), substage (a or b), pretreatment administration of corticosteroid, and serum levels of alkaline phosphatase, sALP and alanine aminotransferase. RESULTS: sALP was not statistically significant with respect to response rate or duration of remission, nor was preinduction glucocorticoid administration. Stage was significant with respect to achieving remission. CLINICAL SIGNIFICANCE: It was found that sALP is not a useful prognostic indicator for response rate and remission duration in dogs with lymphoma.

Gallium scan as a prognostic indicator in neuroblastoma.

Gallium-67 scan results were correlated with the long-term clinical course in ten children with neuroblastoma. The four patients whose primary tumor did not accumulate gallium have exhibited a significantly better survival time (mean duration 68.2 months) as compared to the six patients with gallium-positive tumors (mean duration 16.6 months, P < 0.001). This difference in survival was not explainable on the basis of accepted prognostic indicators, such as age of patient or stage of disease at initial diagnosis. These results indicate that gallium uptake may be a useful prognostic indicator in children with neuroblastoma, independent of other variables.

Peritoneal carcinomatosis and lymph node metastasis are prognostic indicators in patients with Borrmann type IV gastric carcinoma.

BACKGROUND/AIMS: Having observed a lower survival rate of patients with Borrmann type IV gastric cancer, we attempted to determine its prognostic indicators. METHODOLOGY: A total of 103 patients with Borrmann type IV gastric cancer were evaluated; 604 patients with Borrmann types I, II and III were used as references. RESULTS: The results showed that Borrmann type IV gastric cancer were larger, had deeper invasion, more lymphatic and vascular invasions, predominant diffuse type and scirrhous stromal reaction, extensive lymph node metastases and peritoneal carcinomatosis. The 5-year survival rate (11.3%) was significantly lower than that of others (44.7%, P < 0.001). Univariate and multivariate analyses of survival showed that peritoneal carcinomatosis and lymph node metastasis were independently associated with a relative risk of 1.8 and 1.4, respectively. The survival rates of 46 patients with potential curative disease were similar, regardless of various extents of resection. CONCLUSIONS: Peritoneal carcinomatosis and lymph node metastases are prognostic indicators in patients with Borrmann type IV gastric cancer. Optimal surgical strategy for Borrmann type IV gastric cancer remains unclear.
