Long-term prognosis and prognostic indices of IgA nephropathy in juvenile and in adult Japanese.

For a comparative study of IgA nephropathy occurring in Japanese adolescents and adults, the clinical and histological findings and prognosis (follow-up period; 12 +/- 6 years for children and 10 +/- 5 years for adults) were compared. The subjects studied included 98 children and 86 adults. Development into renal failure occurred in 9 children (9.2%) and in 20 adults (23.3%), (p less than 0.01). The actuarial renal survival rate at year 10 after the onset of glomerulonephritis in children and adults was 95% and 80%, respectively, and at year 20, 82% and 50%, respectively. The prognosis was definitely better in the children and this was attributable to the observation that (1) the glomerular injury at the initial biopsy in children was less extensive than in adults; (2) the frequency of complication with hypertension was lower in children (27.6%) than in adults (41.9%), (p less than 0.05); (3) hypertension was one prognostic indice, even in children, after age 30; (4) after age 40, aging and arteriosclerosis were more contributory than hypertension to the progress of IgA nephropathy; and (5) the quantity of intraglomerular immune deposits and the period of deposition were not related of prognostic indices. Thus, in the long-term prognosis of IgA nephropathy in both children and adults, immunological disorders seem to have little influence while factors such as hypertension, arteriosclerosis and aging play important roles.

Prognostic indicators for survival in stage I carcinoma of the lung: a histologic study of 47 surgically resected cases.

In a previous study of 91 consecutive lung cancer cases, we reported that tumor stage was the only significant predictor of survival, with all 5-yr survivors having Stage I disease. Approximately half of the 47 Stage I cases survived 5 yr, so the present study was initiated to determine which histologic features were predictive of survival for Stage I cases. An average of 10 slides per case was evaluated independently by three pathologists, and each slide was subjectively scored using previously agreed criteria for the following parameters: vascular or lymphatic invasion; anaplasia; mitotic rate; inflammatory host response; and the presence or absence of necrosis, tumor giant cells, a central scar, mucin production, benign giant cell reaction, or desmoplasia. Survival was also correlated with patient's age, sex, tumor (T) and nodal (N) status, tumor cell type, and histologic heterogeneity. All three observers found the extent of tumor necrosis to be a significant negative predictor of survival (P less than 0.05). One observer found tumor giant cells to be an adverse factor, another observer found scar carcinomas to have worse survival, and a third observer found lymphocytic inflammatory host response to be a positive predictor and venous invasion to be a negative predictor of survival (P less than 0.05). All other parameters showed no significant correlation with survival. The finding of some parameters which correlated with survival according to one but not the other two observers indicates that the results of studies of histologic prognostic indicators by a single observer may not be valid for other pathologists attempting to use the same subjective criteria.

Significance of cyclin B1 expression as an independent prognostic indicator of patients with squamous cell carcinoma of the esophagus.

PURPOSE: Cyclin B1 plays an important role as a mitotic cyclin in the G(2)-M phase transition during the cell cycle. The aim of the present study was to elucidate the biological significance of cyclin B1 expression in squamous cell carcinoma (SCC) of the esophagus. EXPERIMENTAL DESIGN: We analyzed immunohistochemically the expression of cyclin B1 in the tumor specimens from 120 patients with SCC of the esophagus that had been treated with surgical treatment without any preoperative therapies. RESULTS: The positivity rate of cyclin B1 expression was 56.7% (68 of 120). One-, 3-, and 5-year survival rates in esophageal SCCs with cyclin B1 expression were 82.8, 61.6, and 50.7%, respectively, and they were significantly lower than those in esophageal SCCs without cyclin B1 expression (97.8, 85.5, and 78.6%, respectively; P = 0.005). Cyclin B1 expression was found to be an independent prognostic indicator in esophageal SCCs in a multivariate analysis. When immunostaining for cyclin B1 was classified as a nuclear dominant pattern and cytoplasmic dominant pattern, 1-, 3-, and 5-year survival rates in esophageal SCCs with nuclear dominant expression of cyclin B1 were 66.7, 47.9, and 28.7%, respectively, and they were significantly lower than those in esophageal SCCs with cytoplasmic dominant expression (92.5, 70.0, and 66.3%, respectively; P = 0.005). A multivariate analysis demonstrated that the nuclear dominant cyclin B1 expression was an independent prognosticator in patients with esophageal SCCs expressing cyclin B1. CONCLUSIONS: Our results demonstrate that cyclin B1 expression, especially nuclear dominant expression, can be significant as a prognostic indicator in esophageal SCCs.

Tumor R2* is a prognostic indicator of acute radiotherapeutic response in rodent tumors.

PURPOSE: To test the prognostic potential of tumor R2* with respect to radiotherapeutic outcome. Blood oxygenation level dependent (BOLD) MRI images are sensitive to changes in deoxyhemoglobin concentration through the transverse MRI relaxation rate R2* of tissue water, hence the quantitative measurement of tumor R2* may be related to tissue oxygenation. METHODS AND MATERIALS: Tumor growth inhibition in response to radiation was established for both GH3 prolactinomas and RIF-1 fibrosarcomas with animals breathing either air or carbogen during radiation. In a separate cohort, the baseline R2* and carbogen (95% O2, 5% CO2)-induced DeltaR2* of rat GH3 prolactinomas and murine RIF-1 fibrosarcomas were quantified using multigradient echo (MGRE) MRI prior to radiotherapy, and correlated with subsequent tumor growth inhibition in response to ionizing radiation, while the animals breathed air. RESULTS: A radiation dose of 15 Gy caused pronounced growth delay in both tumor models and transient regression of the GH3 prolactinomas. When the animals breathed carbogen during radiation, the growth delay/regression was enhanced only in the GH3 prolactinomas. The GH3 prolactinomas, which exhibit a relatively fast baseline R2* and large DeltaR2* in response to carbogen breathing prior to radiotherapy, showed a substantial reduction in normalized tumor volume to 66 +/- 3% with air breathing and 36 +/- 5% with carbogen seven days after 15 Gy irradiation. In contrast, the effect of 15 Gy on the RIF-1 fibrosarcomas, which give a relatively slow baseline R2* and negligible DeltaR2* response to carbogen prior to treatment, showed a much smaller growth inhibition (143 +/- 3% with air, 133 +/- 12% with carbogen). CONCLUSION: Quantitation of tumor R2* and carbogen-induced DeltaR2* by MGRE MRI provides completely noninvasive prognostic indicators of a potential acute radiotherapeutic response.

Prognostic indicators in an aggressive pituitary Crooke's cell adenoma.

OBJECTIVE: To investigate prognostic indicators in an aggressive Crooke's cell adenoma of the pituitary. METHODS: The surgically removed tumor was studied by histology, immunohistochemistry and transmission electron microscopy. RESULTS: An aggressive invasive sellar tumor removed by repeated surgeries from a 43-year-old woman with pituitary related Cushing's disease was classified as a Crooke's cell adenoma of the pituitary. The application of several cell proliferation markers confirmed the aggressive nature of the tumor. CONCLUSIONS: The investigation of the present case provides additional evidence that pituitary Crooke's cell adenomas may possess aggressive behavior.

Significance of histological prognostic indicators in patients with carcinoma of the prostate.

The relationship between histological prognostic indicators and their relative significance in prognosis were studied in 139 patients who underwent radical prostatectomy. The estimated progression rates at 5 and 8 years were 14 and 52% respectively for patients with high grade tumours, 25 and 50% for those with capsular penetration, 31 and 58% for patients with seminal vesicle invasion and 23 and 55% for those with lymph node metastases. Each of the 4 parameters yielded an approximately equal increased risk of disease progression at 5 and 8 years. The occurrence of 2 or more risk factors in the same patient did not result in a statistically increased risk of progression at 5 and 8 years. The effect of capsular involvement on progression was directly related to the extent of invasion. The progression rate at 8 years was 3% for patients with mild involvement, 19% for those with extensive invasion and 50% for those with capsular penetration.

Prognostic indicators for outcome following rotator cuff tear repair.

PURPOSE: To examine the prognostic indicators associated with outcome following rotator cuff surgery. METHODS: A retrospective evaluation of records on 1120 shoulders (1067 patients) with rotator cuff tear treated by surgery was performed. Preoperative, intra-operative and postoperative factors were analysed by Kendall's Tau-b correlation analysis and logistic regression analysis. RESULTS: Positive correlations were seen between the type of tear and the number of tendons involved, retraction, age, degeneration, subacromial bone spur, surgical technique, preoperative and postoperative muscle power, surgical outcome, and preoperative abduction on Kendall's Tau-b analysis. There was a positive correlation seen between degenerative change and age, number of tendons involved, retraction, preoperative pain, tear type, and preoperative musclepower on logistic regression analysis. Additionally, positive correlations were seen between good surgical postoperative outcome and postoperative activities of daily living, preoperative pain, postoperative muscle power, preoperative activities of daily living, tear type, preoperative external rotation, preoperative muscle power, number of tendons involved, preoperative pain, and duration of symptoms. CONCLUSION: Ageing was found to be the major factor in progressive degeneration of the rotator cuff, and should be considered the single most important contributing factor in the pathogenesis of rotator cuff tears. In addition, degenerative tendonopathy appeared the primary pathology in rotator cuff tear, preceding hypertrophic spur formation. Rotator cuff tears are therefore unlikely to be initiated by impingement; rather, they develop as an intrinsic degenerative tendonopathy.

Risk factors in stage III epithelial ovarian cancer: previous sterilisation is an adverse independent prognostic indicator.

OBJECTIVES: To determine whether past history of pelvic surgery is of prognostic significance in stage III epithelial ovarian cancer. METHODS: A retrospective review of 140 women with stage III epithelial ovarian cancer. RESULTS: Sixteen women had previously undergone pelvic surgery including eight sterilisations (6%), seven hysterectomies (5%) and one ovarian cystectomy (0.7%). Women with a past history of sterilisation were significantly younger (median age, 46 years) than women without a past history of sterilisation (median age, 63 years), and also significantly younger than women with a past history of hysterectomy (median age, 58 years). In addition, the sterilisation procedure was performed at a significantly younger age than the hysterectomy procedure (p=0.008). On multivariate analysis comparing previous pelvic surgery, previous malignancy, place of surgery, interval/secondary debulking, presence of concomitant tumour, performance of bowel surgery, histological grade, histological type, size of residual disease and age, all of the following were seen to be independent variables associated with outcome survival; previous sterilisation (p=0.0012), age (p=0.0074), histological type (p=0.025), histological grade (p=0.0017) and size of residual disease (p=0.0043). CONCLUSION: Past history of sterilisation appears to be an adverse independent prognostic indicator in women presenting with stage III epithelial ovarian cancer. To have developed ovarian cancer despite the protective effects of a sterilisation procedure against environmental factors might possibly suggest a predisposition to ovarian cancer in these women. Further studies are indicated to confirm the present results.

Studies on the correlation among the fucosylation index, concentration of alpha-fetoprotein and des-gamma-carboxy prothrombin as prognostic indicators in hepatocellular carcinoma.

Our previous results showed that the fucosylation index (FI) was considered to be a useful prognostic factor in patients with hepatocellular carcinoma (HCC). On the other hand, serum concentrations of alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP) were regarded as prognostic indicators. However, the relationship among FI, AFP, and DCP as prognostic factors remained unknown. The aim of this study was to elucidate the correlation among these three prognostic factors. One hundred and seventy-six patients with HCC from 1990 to 1998, who showed increment of serum AFP concentrations more than 30ng/ml before treatment, were examined in the present study. FI was determined in these patients by crossed immunoaffino-electrophoresis in the presence of Lens culinaris agglutinin. FI of AFP was defined as the percentage of the L. culinaris agglutinin (LCA)-reactive species in total AFP (same as L3 fraction). Serum concentrations of DCP were also measured. Enrolled patients with HCC underwent transcatheter arterial embolization, chemoembolization, percutaneous ethanol injection, and/or percutaneous microwave coagulation therapy. The current patients status was the one which was confirmed at the end of March 2001. Analysis by the Cox's proportional hazards model showed that FI, AFP, and DCP were significant prognostic factors. When the tentative demarcation levels of FI, AFP, and DCP were set at 18%, 200ng/ml, and 0.06arbitrary units (AU)/ml, respectively, the following results for the prognostication of patients with HCC were obtained. First, the survival rates in the groups with one out of the three optional markers over the demarcation level were significantly lower than the survival rates of other groups, whose optional one marker was equal to or less than the demarcation level, respectively. Next, the survival rates in the groups in which two out of three optional markers were over the demarcation levels were lower than the survival rates of other groups, whose optional two markers were equal to or less than the demarcation levels, with high significance. On the contrary, there was absence or attenuation of statistically significant differences in the survival rates between the groups in which two of the three optional markers showed no accordant results (high FI and low AFP versus low FI and high AFP, low FI and high DCP versus high FI and low DCP, high DCP and low AFP versus low DCP and high AFP). Finally, we compared the survival rates between the HCC groups, whose optional one marker was over the demarcation level and whose remainders were equal to or less than the demarcation levels and another HCC group whose optional one marker was equal to or less than the demarcation level and whose remainders were over the demarcation levels to reconfirm the weight of each prognostic factor. These comparisons together with Cox's analysis showed that the weight of each prognostic factor in the survival rates is consecutively ordered as DCP, FI, and AFP. The present study indicates that measurements of FI, AFP, and DCP from the sera before the initial treatment improve prognostic estimates and appraisal of the therapeutic outcome in patients with HCC.

Chest radiograph scores as potential prognostic indicators in severe acute respiratory syndrome (SARS).

OBJECTIVE: We analyzed serial chest radiographic scores for lung opacification in patients with severe acute respiratory syndrome (SARS) for temporal changes and differences between fatal and discharged cases. We sought to establish the earliest radiographic scores sensitive as potential prognostic indicators of fatal outcomes. MATERIALS AND METHODS: Chest radiographs that had been obtained from presentation until the death or discharge of 313 patients with SARS were scored on the basis of the percentage area and location of lung opacification. Profile analysis and univariable logistic regression were performed on these radiographic scores. RESULTS: Despite the increased mortality risks of advanced age and male sex, no significant difference was seen in the percentage area of opacification (AO%) between the sexes in either the group of patients with fatal outcomes or the group of patients who were discharged. No difference existed between age groups (< 65 years vs >/= 65 years), except for the radiograph showing the peak lung opacification in the deceased group in which the lungs of older patients had less opacification than those of younger patients. The radiographic scores obtained by day 7 were the earliest ones with good performance in prognostic prediction. The model showed good discriminatory performance, indicated by high C-indexes for receiver operator characteristic curves (0.86 for AO% and 0.90 for the number of opacified zones). The predicted proportion of patients with fatal outcomes showed high agreement with percentage of patients who died (goodness-of-fit statistic p = 0.18 for AO%, 0.73 for the number of opacified zones). By day 7, crude odds ratio of death was 1.73 per 5% of AO% (p < 0.0001) or 2.93 per lung zone opacified (p < 0.0001). CONCLUSION: Chest radiographic scores (percentage of lung or the number of zones opacified) by day 7 could be used as fatal prognostic indicators.

CSF/blood glucose ratio and other prognostic indices in pyogenic meningitis.

Fifty cases of pyogenic meningitis were examined for various prognostic indices, especially cerebrospinal fluid (CSF)/blood glucose ratio. Overall mortality was 40%. Age below one year and depressed level of consciousness were associated with high mortality. Illness of more than 7 days, presence of associated illness and absence of neck rigidity were not found to be statistically significant factors associated with higher mortality. CSF leucocyte count of more than 1000 cells/cmm and CSF protein more than 500 mg/dl were statistically significant factors associated with higher mortality. In cases of CSF glucose level below 20 mg/dl and CSF/blood glucose ratio below 0.2, the increase in mortality was highly significant. CSF/blood glucose ratio in cases who recovered was much higher than those who died. CSF/blood glucose ratio increased to normal in cases who recovered but remained low in cases who expired.

[Successive myocardial fatty acid metabolic imaging in patients with dilated cardiomyopathy: usefulness as a prognostic indicator].

To evaluate the prognostic value of fatty acid metabolic imaging in patients with idiopathic dilated cardiomyopathy (DCM), we performed myocardial imaging with 123I-BMIPP (BMIPP). We studied 23 patients with DCM who were admitted because of congestive heart failure (CHF) and after discharge the stable condition persisted for more than one year. BMIPP imaging was obtained when CHF recovered (first study) and the second study was performed one year after the first study. From BMIPP imaging we calculated % Uptake (percentage of cardiac uptake of isotope to total injected dose) and Defect Score (degree and extent of regional abnormality in BMIPP uptake, DS). In the first study, we performed myocardial imaging with 201T1 to calculate Uptake Ratio of BMIPP (% Uptake of BMIPP divided by % Uptake of 201T1, UR). During the follow up period of 18.2 +/- 9.5 months (4.5-39.6 months) after the second study, cardiac event developed in 8 patients (cardiac death; 4, deterioration of CHF; 4). On univariate analysis, the following indices differed significantly between the event and event-free groups; left ventricular end-systolic dimension, graded DS, UR and % Uptake of 201T1 at the first study, % Uptake of BMIPP and DS at the second study, difference of % Uptake of BMIPP and DS between the first and second study, and newly designed index from graded DS of the first study and its change in the second study (Defect Index, DI). Cox proportional hazard analysis showed that DI (p = 0.0026) and age (p = 0.0262) were independent predictors of cardiac events. In patients with DI > or = 3, the relative risk of cardiac event was 25.0 times greater than that in patients with DI < or = 2. These data suggested that the extent and degree of regional abnormality of BMIPP uptake (DS) and its changes with time were useful for evaluating the prognosis in patients with DCM even though a clinically stable condition is persisting.

Identification of novel prognostic indicators in burned patients.

The size and depth of burn and patient age are useful early prognostic indicators in burned patients, but have limited value in predicting which patients in a given cohort are likely to die. The objective of this study was to identify additional variables in the first 10 days of burn injury which could better predict patient outcome. Variables consisting of demographic information, routine laboratory data, and clinical observations on 89 burned patients (63 survivors and 26 nonsurvivors) were analyzed. Compared to survivors, nonsurvivors had significantly larger burns (58 +/- 23% vs. 37 +/- 17%; p less than 0.0002) and a higher incidence of Gram-negative septicemia (20 of 26 [77%] vs. 24 of 63 [38%]; p less than 0.001). Potential prognostic variables were subjected to multivariate logistic regression analysis for each of the first 10 days following burn injury in order to identify a combination of parameters which predicted patient outcome. The regression analyses revealed that, as previously demonstrated, patient age and burn size were significant predictors of mortality on admission and throughout the first 10 days postburn. In addition, absolute monocyte count (AMC), absolute lymphocyte count (ALC), maximum daily temperature (Tmax), and BUN were also significant predictors (p less than 0.05). These data indicate that logistic regression models can identify simple prognostic variables in burned patients which may improve clinicians' ability to identify high-risk patients early in the course of their burn injuries.

Immunohistochemical detection of p53 protein as a prognostic indicator in prostate carcinoma.

UNLABELLED: THE AIM of our study was to evaluate the prognostic significance of p53 protein immunoreactivity for prostate cancer and to determine whether p53 immunoreactivity correlates with the Gleason tumor grade in primary adenocarcinoma. Prostate fragments were fixed in 10% formalin, paraffin-embedded, sectioned and standard Hematoxylin-Eosin stained, then examined using histological grade (Gleason system). P53 expression was studied using immunohistochemistry with monoclonal antibody anti-p53, 1 : 100 (BIOX) on tissue samples obtained during transurethral electroresection, adenomectomy or needle biopsy in 30 patients with prostate carcinoma: group 1 (n = 7) Gleason score 5, group 2 (n = 10) Gleason score 6, group 3 (n = 11) Gleason score 7, group 4 (n = 2) Gleason score 8. Also, we noted the cases with high grade prostatic intraepithelial neoplasia (high grade PIN). All specimens prior to initiation of any treatment were submitted for this study. Staining was defined as positive for p53 whenever any specific nuclear staining was detected. We considered tumors to overexpress p53 protein only when strong nuclear staining was present. Cases exhibiting weak or equivocal nuclear staining were classified as negative, as were cases with extremely rare isolated positive nuclei. A semiquantitative scoring system was employed to assess the level of p53 reactivity. Six of 17 (35.2%) moderately differentiated tumors (Gleason score 5-6) and five of 13 (38.4%) moderate to poorly differentiated (Gleason score 7 and above) revealed strong nuclear positivity for p53. In addition, we noted occasional p53 reactivity in high-grade PIN. CONCLUSIONS: We interpret these data to demonstrate a positive association between p53 reactivity and higher Gleason grade tumors; p53 might be an independent prognostic indicator among metastatic risk cases.

Epidermal growth factor receptor expression as a prognostic indicator in breast cancer.

The significance of epidermal growth factor receptor (EGFR) status as a prognostic indicator was investigated by a competitive binding assay in 135 primary breast cancer patients. 55 patients (41%) were EGFR positive and EGFR status was negatively correlated with oestrogen receptor (ER) status (P less than 0.01). 5-year postoperative follow-up showed that relapse-free survival for EGFR positive patients was significantly worse than that for EGFR negative patients (P less than 0.05). There was no difference between the two groups in tumour size, axillary node involvement, age and menopausal status. Analysis by axillary node status demonstrated the poor prognosis of the EGFR positive group in node positive patients. As yet, no difference in prognosis has been seen in node negative patients. A higher frequency of haematopoietic relapse was observed in EGFR positive patients. Simultaneous or sequential EGFR measurements in primary tumour and metastatic sites of 34 patients showed that expression of EGFR was more enhanced in metastatic sites.

[Clinical significance of argyrophilic nucleolar organizer regions (AgNOR) and microvessel quantitation by staining for factor VIII-related antigen as prognostic indicators in stage I breast cancer].

The clinical significance of AgNOR and microvessel quantitation as prognostic indicators in Stage I breast cancer were examined. This study included 99 patients with Stage I breast cancer, with a median follow-up period of 119 months. AgNOR was stained by Crocker's method and microvessels were identified by immunohistochemical staining for Factor VIII-related antigen in formalin-fixed, paraffin-embedded primary tumors. AgNOR score related with tumor size. Microvessel count was related to estrogen receptor status. When patients were classified into two groups by the mean AgNOR score, higher scores had a tendency to be correlated with shorter overall survival. And when classified by microvessel count, higher counts were significantly associated with shorter overall, survival (p < 0.01). The microvessel count might be a useful predictor and the AgNOR score could be used to corroborate predictions for identifying patients at high risk for relapse and death in Stage I breast cancer.

Radiographic parameters as prognostic indicators for healing of class II furcation defects.

OBJECTIVE: To evaluate radiographic measurements for use as prognostic indicators for healing of class II furcation defects following regenerative therapy. MATERIAL AND METHODS: In 17 patients (eight females), 33 class II furcation defects (mandibular buccal (n=10) and lingual (n=12), and maxillary buccal (n=11)) were treated using the barrier membrane technique. Twenty-six furcations were treated using a bioabsorbable membrane, while a nonresorbable membrane was used to treat the remaining seven furcation defects. Clinical parameters and standardized radiographs were obtained before as well as 6 and 24 months after therapy. All radiographs were digitized and evaluated by an examiner blinded to the clinical data. The following distances were measured: cemento-enamel junction line (CEJ-line) to alveolar crest (AC) at the furcation site (AC-CEJ line), CEJ-line to the furcation fornix (Fx-CEJ line), width of the furcation at the level of the AC (FW) as well as the distance from Fx to a straight line between the AC mesial and distal of the tooth (Fx-AC line). RESULTS: Statistically significant (p<0.001) horizontal attachment gains could be observed 6 and 24 months after therapy (6 months: 1.49+/-0.85 mm; 24 months: 1.14+/-0.91 mm). However, a small but statistically significant (p=0.031) attachment loss of 0.35 mm was observed between the 6 and 24 months examination. Multilevel regression analyses identified baseline probing depth (p=0.0017) and 3 of the radiographic distances as prognostic factors: Fx-CEJ line (p=0.014), FW (p=0.0535), Fx-AC line (p=0.0827). CONCLUSION: The analysis of presurgical radiographs may yield information on the success of the regenerative therapy of buccal and lingual class II furcation defects. A long root trunk, a wide furcation entrance and an Fx coronal to the AC have negative influences on the success of therapy. Further, a deep probing depth at the furcation site at baseline increases the likelihood for more favourable horizontal attachment gain in furcations.
