Carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA) and other prognostic indicators in squamous cell lung cancer.

Multivariate models of survival have been established for both small cell and non-small cell lung cancers. So far, no study has focussed on squamous cell types. Previous demonstrations of the prognostic value of the tissue polypeptide antigen (TPA) and, partially, of the carcinoembryonic antigen (CEA) are based on univariate analyses of survival. These analyses do not account for the other prognostic factors. In the present study, we report the combined influence of various clinical and biological characteristics on the survival duration of 360 patients with a newly diagnosed squamous cell carcinoma of the lung. The study comprised 29 variables, including age, sex, smoking habit (SH), symptoms at diagnosis, the Karnofsky performance status (KPS), weight loss (WL), radiological findings, various disease extent parameters (DEP), CEA and TPA. Preliminary univariate analyses showed that 20 variables were survival-related. The Cox proportional hazards regression analysis selected stage of disease, KPS, TPA, WL, the existence of bone metastases, and SH as independent factors of prognosis (global chi-square: 122.40, P = 0.0000). A second multivariate analysis, performed with the same covariates but excluding DEP, revealed previous pulmonary diseases and CEA to be, in addition to KPS, TPA, SH, and WL the next most influential prognostic determinants. Also in squamous cell lung cancer, classifications based on the Cox's prediction equation may improve individual counseling and patient selection for therapeutic trials. In this malignancy, TPA shows an independent and strong prognostic significance while CEA shares informations of diverse other prognostic factors and seems to be less important.

[Rosette forming lymphocytes as prognostic indices in idiopathic thrombocytopenic purpura].

The study included 12 patients with acute ITP to whom subpopulations of rosette forming lymphocytes were determined in peripheral blood and in serial form, the number of platelets to establish a correlation as prognostic index in the evolution of the disease. No correlation was found between the progressive increment of platelets in the evolution of the disease. However, in patients with a tendency to remission, the percentage of E(T) rosette forming lymphocytes was low and normal that of EAC (B) lymphocytes. Dissimilarly, it was seen that in patients without tendency to remission, the percentage of T and B rosette forming lymphocytes was within normal limits. This seems to show that determination of the subpopulations of lymphocytes may be useful as a prognostic index in this stage of the disease.

Survey of speech and language skills with prognostic indicators in 116 patients with Cornelia de Lange syndrome.

Speech and language evaluations of 116 patients, ages 2 months to 29 years, with Cornelia de Lange syndrome (CdLS), also known as Brachmann-de Lange syndrome, were conducted to survey speech and language skills and to ascertain the prognostic value of related variables. These patients were evaluated at conferences of the CdLS Foundation. The data from these evaluations were then analyzed using the database program of Paradox 3.5. The findings indicated that 53% of the children who were 4 years or older combined 2 or more words into sentences and 33% had no words or only 1-2 words. Four percent were judged to have language skills within normal to low-normal limits. Children who were not talking at all or who were severely delayed in language skills had at least one of the following characteristics: birth weight under 5 lbs.; a reported diagnosis of moderate-to-severe hearing impairment; upper limb malformations; poor abilities to relate socially; and/or severe motor delays, e.g., they did not sit up until after age 25 months or did not walk until after 35 months.

Cellular DNA content parameters as prognostic indicators in human astrocytomas.

OBJECTIVE: Clinical parameters such as grade, size and/or location of the tumor are good predictors of outcome in patients with astrocytoma. The objective of this study was to determine whether DNA content parameters have a prognostic significance for this group of tumors. METHODS: Following optimization and validation of methodology for evaluating cellular DNA content parameters (CDCP), tumor DNA ploidy and percent S phase fraction (SPF) were determined from 64 patients using formalin fixed, paraffin embedded specimens (mean coefficient of variation=4.94) obtained over a 10-year period. Median survival times correlated with grade (I/II=1154 vs. III/IV=483days, P=0.0317). Fifty-five percent of the specimens contained DNA aneuploid (DNA-A) components (average SPF=18.3%) and 45% were DNA diploid (DNA-D) (average SPF=9.6%). Survival did not correlate with overall differences in DNA ploidy (DNA-D=181 vs. DNA-A=206days, P=0.6314) when treated and untreated tumors were analyzed. However, a trend for prolonged median survival was observed in patients whose tumors were untreated with respect to cytotoxic therapy based on DNA ploidy status (DNA-D=275 vs. DNA-A=15days, P=0.3408). Survival for all patients did not correlate with median SPF (<13.5% av.=121 vs. >13.5% av.=154days, P=0.6534). CONCLUSION: DNA content parameters may correlate with the natural history and treatment outcome of newly diagnosed untreated patients with astrocytomas.

Macroscopic tumor size as a simple prognostic indicator in patients with gastric cancer.

BACKGROUND: In some cancers, such as breast and lung, tumor size is included in the classification of disease stage. However, it's clinical significance remains elusive in gastric cancer. METHODS: To investigate the prognostic significance of macroscopic tumor size, we reviewed 1473 gastric cancer patients who underwent curative gastrectomy. RESULTS: An appropriate threshold of tumor size affecting patient survival was 8 cm. Patients were divided into 2 groups as follows: small size group (SSG=tumor size<8 cm) and large size group (LSG=tumor size>or=8 cm). LSG tumors were frequently observed in patients with undifferentiated types and with lymphatic and venous invasion. Moreover, tumor size was significantly related to depth of invasion and lymph node metastasis. The prognosis of LSG patients was significantly worse than that of SSG patients. Multivariate analysis showed that tumor size was an independent prognostic factor along with depth of invasion, lymph node metastasis, and lymphatic invasion. Recurrence patterns differed between the 2 groups. Peritoneal recurrence was observed in LSG more frequently than SSG patients (P<.001), whereas hematogenous recurrence was observed in SSG more frequently than in LSG patients (P<.05). The survival rates of patient with stages II-, IIIa-, and IIIb-LSG disease were almost the same as those with stages IIIa-, IIIb-, and IV-SSG disease, respectively. COMMENTS: Tumor size serves as a simple predictor of survival in patients with gastric cancer.

Prognostic indicators in pituitary tumors.

Recent advances in molecular pathology have shed light not only on the cellular composition and derivation of various tumors, but also on their growth potential, likelihood of recurrence, and prognosis. The development of reliable and prognostically informative methods of assessing tumor behavior is particularly important in pituitary tumors, where no precise correlation exists between morphology and clinical aggressiveness. Among the numerous morphologic techniques that have been introduced in the last three decades, some have gained popularity due to their reliability and ease of performance, whereas others have fallen from favor due to their inconsistency and insensitivity in distinguishing indolent from aggressive pituitary tumors. Yet others, due to cost and complexity, never came into general use. We predict that the immunohistochemical methods now in use for assessment of tumor behavior will be complemented and partly replaced by molecular genetic procedures in the future.

Prognostic indicators in locally advanced gastric cancer (LAGC) treated with preoperative chemotherapy and D2-gastrectomy.

BACKGROUND AND OBJECTIVES: Neoadjuvant chemotherapy is increasingly considered an effective treatment option for patients with gastric carcinoma. Aim of the study is to evaluate the prognostic significance of the pathological response and of known prognostic factors in a group of accurately staged locally advanced gastric cancer (LAGC) patients. METHODS: Thirty-three patients with LAGC, staged by laparoscopy, underwent D2-gastrectomy after preoperative chemotherapy. Survival was calculated by Kaplan-Meier method and differences were assessed by the Log-rank and Breslow test. Multivariate analysis was performed using the Cox proportional hazard model in backward stepwise regression. RESULTS: Curative resection (R0) was achieved in 81.8% of patients. A complete or subtotal pathological response was documented in 3 and 6%, respectively. Nineteen out of thirty-three (57.6%) patients were alive and 16 of them were free of relapse at last follow-up. Survival rates were 81, 67, and 59% at 12, 24, and 36 months, respectively. At univariate and multivariate analysis, only R0 resection was found to be an independent prognostic factor. CONCLUSIONS: In the current study, R0 resection is the most important prognostic factor for resectable LAGC; according to our results we feel encouraged to consider neoadjuvant chemotherapy a promising modality for increasing the R0-percentage of gastric carcinoma patients who could benefit from a curative surgery.

CD38 expression as a prognostic indicator in chronic lymphocytic leukaemia.

Staging systems and laboratory features help predict survival in chronic lymphocytic leukaemia but they do not distinguish patients who will progress from those whose disease will remain indolent. CD38 expression has emerged as an independent prognostic factor, yet there is debate as to what level of CD38 affects prognosis. We plotted the hazard ratios for the treatment-free interval (TFI) between the higher and lower groups defined by CD38 cut-offs from 0 to 100%. The maximum hazard ratio was achieved for a cut-off of 7%. We examined by triple colour analysis the values for CD38 in 289 untreated patients using both >or=30 and >or=7% as thresholds for prognosis. Using a >or=7% threshold (but not >or=30%), we showed a significant correlation with advanced stage and male sex. The interval from diagnosis to first therapy or TFI was longer (median 36 months) in patients with <7% CD38 positive cells than those with >or= 30% (8.7 months) or with intermediate values between 7 and 29% (P<0.00005). The <7% threshold also identified patients in stage A with a long TFI (P=0.0001). Multivariate analysis showed that CD38 has independent prognostic value for TFI in all patients. In 135 patients tested for deletions of p53, 13q14 and 11q23 and for trisomy 12, we showed a correlation between 13q14 deletion and <30%/<7% CD38 positive cells and a tendency for trisomy 12 to be associated with >or=30%/>or=7% CD38 positive cells. We conclude that 7% may be a more useful threshold for disease progression than higher values of CD38.

The Bcl-2 protein: a prognostic indicator strongly related to p53 protein in lymph node-negative breast cancer patients.

BACKGROUND: The bcl-2 gene (also known as BCL2) encodes for a mitochondrial protein thought to prevent apoptosis of normal cells. The protein has been detected by immunohistochemical procedures in hormonally regulated epithelia. PURPOSE: We analyzed the predictive relevance of Bcl-2 expression on 6-year relapse-free and overall survival in lymph node-negative breast cancers in relation to pathologic (tumor size) and biologic ([3H]thymidine-labeling index, p53 protein expression, and estrogen receptor [ER] status) features. METHODS: The expression of Bcl-2 and p53 was detected by immunohistochemistry on paraffin-embedded sections from 283 node-negative resectable breast cancers treated with local-regional therapy alone until relapse. The [3H]thymidine-labeling index was evaluated on histologic sections after incubation of fresh tumor tissue with [3H]thymidine, and ER content was determined by the dextran-coated charcoal absorption technique. RESULTS: A significantly higher fraction of Bcl-2-positive cells was observed in small, ER-positive, slowly proliferating, and p53-negative tumors than in large, ER-negative, rapidly proliferating, and p53-positive tumors. A stronger association was observed between Bcl-2 and p53 expression than between these variables and [3H]thymidine-labeling index. In univariate analysis, Bcl-2 and p53 expression, [3H]thymidine-labeling index, tumor size, and ER status were indicators for relapse-free and, with the exception of tumor size, overall survival within 6 years of surgery. In multivariate analysis, Bcl-2 failed to maintain its prognostic role for relapse-free and overall survival in the presence of p53 expression, whereas the [3H]thymidine-labeling index was still statistically significant as a predictor for both events. CONCLUSION: The predictive role of Bcl-2 expression on 6-year relapse-free and overall survival was mainly dependent on p53 expression.

Preoperative CYFRA 21-1 level as a prognostic indicator in resected nonsmall cell lung cancer.

Cytokeratin 19 is particularly abundant in carcinoma of the lung. The CYFRA 21-1 assay has recently been developed for detection of a cytokeratin 19 fragment in serum. In the current study, the prognostic information provided by the CYFRA 21-1 assay in operable nonsmall cell lung cancer (NSCLC) was analysed. Serum levels of CYFRA 21-1 were measured using an immunoradiometric assay (DiaSorin) in 94 patients with operable NSCLC. Survival and disease-free survival curves related to initial levels of this marker were estimated using the Kaplan-Meier method. Elevated preoperative CYFRA 21-1 levels were identified in 42% of patients with NSCLC. The number of patients with elevated levels of this marker increased with tumour node metastasis (TNM) stage (p=0.02). In univariate analysis elevated levels of CYFRA 21-1 were significantly associated with poor overall survival (p<0.001) and with disease-free survival (p<0.001). The results remained significant when the comparisons were adjusted, using the stratified log-rank test, for patient's TNM stage (p<0.001 for both overall and disease-free survival). Elevated preoperative levels of CYFRA 21-1 decreased the probability of survival or surviving without recurrence 15 months or more after the operation. This was confirmed by the results of the multivariate analysis. In conclusion, CYFRA 21-1 may be an independent prognostic parameter of survival and tumour relapse in nonsmall cell lung cancer and may be useful in identifying resected cancer patients at high risk for treatment failure.

The role of serum CEA as a prognostic indicator in stage II and III breast cancer patients treated with adjuvant chemotherapy.

Carcinoembryonic antigen (CEA) values in 529 patients treated in two consecutive adjuvant chemotherapy protocols were analyzed to determine if CEA values correlated with disease-free status or prognostic utility. CEA values were evaluated preoperatively, before chemotherapy, at the conclusion of chemotherapy, and during postchemotherapy followup. The sensitivity of CEA for predicting disease recurrence was low; however, any abnormal CEA at the conclusion of chemotherapy and during followup significantly correlated with reduced disease-free and overall survival. A CEA value greater than or equal to 20 ng/ml at the end of chemotherapy or during followup was highly specific and a strongly positive predictor for the presence of metastases. Abnormal CEA values before chemotherapy that became normal at the conclusion of chemotherapy were associated with a significantly reduced recurrence rate. An abnormal CEA value obtained before or after adjuvant chemotherapy is clinically useful and can provide prognostic information.

Preoperative serum albumin level is a prognostic indicator for adenocarcinoma of the gastric cardia.

Among patients with adenocarcinoma of the gastric cardia, we noted that patients with higher preoperative serum albumin levels appeared to survive longer than patients with lower levels. Thus, we evaluated serum albumin as a prognostic factor for patient survival. From 1987 to 1997, 314 patients with adenocarcinoma of the gastric cardia underwent curative resection. Patient serum albumin levels were evaluated on the second day after admission, before any nutritional support. Patients were divided into two groups: those with normal serum albumin levels (>3.5 g/dl) and those with abnormal serum albumin levels. The perioperative mortality and morbidity were 5.7% (18 of 314) and 22.3% (70 of 314), respectively. The surgical resectability rate was significantly better among patients with normal serum albumin levels (P < 0.001). The 5-year overall survival rate of patients with normal serum albumin levels was also better than those with abnormally low serum albumin levels (38.4% versus 19.1%, P=0.0003). In each cancer stage, the 5-year survival rate of patients with normal serum albumin levels was better than that among those with hypoalbuminemia. By multivariate analysis, serum albumin level and the pathologic T, N statuses were independent factors correlated with prognosis. Preoperative serum albumin level correlated highly with resectability and survival. Patients with abnormal serum albumin levels had worse survival than did those with normal serum albumin levels. We recommend that postoperative adjuvant therapy be given to all patients with hypoalbuminemia preoperatively.

Amyotrophic lateral sclerosis: prognostic indicators of survival.

Amyotrophic lateral sclerosis (ALS) has a fatal outcome in about three years, but survival is known to vary considerably, making it difficult to predict disease duration in individual cases. The aim of this study was to investigate possible early prognostic factors of ALS survival. We included 123 probable or definite cases of ALS, with disease onset between 1989 and 1998, and with a follow-up of at least one year. Survival functions were obtained using both the Kaplan-Meier and the actuarial methods. Subgroups, formed on the basis of gender, area of residence, work, and age at and site of onset, were compared using the logrank test and Cox's proportional hazards method (survival functions), and applying the Grizzle, Starmer, Koch (1969), and Koch, Johnson, Tolley (1972) methods (one-year survival probability trends). The survival curves dipped sharply in the first three years, followed by a flattening trend, with 50% of patients dying within 2.5 years, and 89% over seven years. The clinical form with lower limb onset was associated with longer survival than the upper limb onset and bulbar forms (median survival: 39, 27, and 25 months, respectively). Survival was also affected by age at onset (median survival: 34, 27, and 23 months for onset <60, 60-75, and >75 years, respectively), area of residence (median survival: 24 months in mountainous areas, 32 elsewhere), and type of work (median survival: 25 months in agricultural workers, 33.5 in others). Gender did not influence survival, whereas percutaneous endoscopic gastrostomy placement and invasive ventilation did. The estimation of individual ALS survival is important to allow the patient to plan for his future and to make optimal use of medical and community resources. Although age at and site of onset, area of residence, and agricultural work were found to influence survival, there remains an unexplained heterogeneous progression of the disease, suggesting the influence of other, as yet unknown, prognostic factors. The identification of a definite set of prognostic factors may allow physicians to make more reliable survival predictions at diagnosis.

Cellular dyscohesion in fine-needle aspiration of breast carcinoma. Prognostic indicator for axillary lymph node metastases?

The role of fine-needle aspiration (FNA) in the diagnosis of breast carcinoma is established. We evaluated whether the degree of cellular dyscohesion and the nuclear grade in FNA material of breast carcinomas are reliable prognostic predictors for ipsilateral axillary lymph node metastasis. FNA specimens from 98 women with infiltrating ductal and infiltrating lobular carcinomas were evaluated by 2 observers for degree of cellular dyscohesion and nuclear grade. Follow-up specimens from lumpectomy and/or mastectomy with axillary dissection were available for each patient. By univariate analysis, degree of cellular dyscohesion and nuclear grade were not predictive of axillary lymph node metastasis regardless of tumor size. High histologic grade, size greater than 2 cm, and patient age younger than 52 years were significant predictors of metastasis. By multivariate analysis, size greater than 2 cm and age younger than 52 years were statistically significant for lymph node metastasis. In contrast with a published study, the results of the present study fail to show cellular dyscohesion in FNA specimens as predictive of lymph node metastasis; however, the scoring method for determining the degree of cellular dyscohesion is reproducible between 2 independent observers.

Ruptured abdominal aortic aneurysms--prognostic indicators and complications affecting mortality. A local experience.

Although elective abdominal aortic aneurysm (AAA) repair can be done with a less than 5% mortality rate, ruptured AAAs have a 32-85% mortality rate. The aims of this study were: (i) to identify prognostic factors affecting mortality; (ii) to identify and assess the impact of postoperative complications on mortality; and (iii) to try to identify a subgroup of patients who would not benefit from surgery. The records of 54 patients presenting with ruptured AAAs were reviewed; 49 of these patients were operated on, 43 of them males and 6 females (mean age 67 years). The operative mortality rate was 44%, most patients who died doing so in the intensive care unit. In 14 cases AAA was diagnosed before rupture--6 of these patients died. Factors that had a significant effect on mortality were: (i) associated ischaemic heart disease--83% of these patients died postoperatively; (ii) the degree of shock on admission--66% of patients with a blood pressure on admission of 85 mmHg or less died; and (iii) the number of postoperative complications per patients--those with 2 or more complications had an 83% mortality rate. Factors that did not correlate statistically with mortality were age, time interval to surgery, volume and composition of intra-operative fluid therapy, and length of surgery. The most important correctable error was failure to operate electively. From the factors assessed it was not possible clearly to identify a subgroup of patients in this study who should have been excluded from surgery.

Study on Ki-67 immunoreactivity as a prognostic indicator in patients with advanced gastric cancer.

BACKGROUND: Cell proliferation characteristics may reflect the aggressiveness of gastric tumors and their eventual prognosis. The aim of this study was to evaluate whether the proliferative activities determined by the antibody Ki-67 could be used as a prognostic predictor in patients affected by advanced gastric cancer. METHODS: The prognostic significance of proliferative activity was investigated in 56 patients who underwent curative gastrectomy (R0) for advanced gastric cancer using the monoclonal antibody Ki-67. The patients were divided into three groups according to the Ki-67 labeling index of the tumors: < 10% (18 cases), 10-40% (21 cases) and > 40% (17 cases). The Cox regression model was used to evaluate the prognostic significance of the Ki-67 index controlling for age, gender, histology, depth of tumor invasion and node metastasis. RESULTS: There was no significant relationship between the Ki-67 index and wall invasion (P = 0.80) or nodal status (P = 0.73). The cumulative 3-year survival rates (95% Cl) were 61.0% (35.3-79.2%) in patients with Ki-67 index < 10%, 52.4% (29.7-70.9%) with Ki-67 index 10-40% and 52.9% (27.6-73.0%) with Ki-67 index > 40% and the differences were not statistically significant (P = 0.93). Also in multivariate analysis the proliferative activity did not independently affect survival (P = 0.98). An interaction between Ki-67 index and age was found and Ki-67 index > 40% was significantly associated with a poor prognosis in patients over 68 years old (P = 0.004). CONCLUSION: Our study indicated that the proliferative activity in gastric cancer, determined with the monoclonal antibody Ki-67, does not influence the survival except in elderly patients (> or = 68 years old).

Prenatal diagnosis of vein of Galen aneurysmal malformation: report of two cases with proposal for prognostic indices.

Vein of Galen aneurysmal malformation (VGAM) is a rare, intracranial vascular anomaly that, until recently, has usually been diagnosed postnatally. Today, however, with the advances in high-resolution ultrasonography and colour Doppler, prenatal diagnosis is relatively easy. Due to novel intravascular embolization techniques, the prognosis of neonates with VGAM has markedly improved. A healthy infant with normal neurodevelopmental and cardiovascular status is now a reality. For the best outcome, however, careful planning of the appropriate time, mode, and place of delivery should be undertaken. To achieve this goal, in utero prognostic factors should be determined. This report illustrates, for the first time, prenatal ultrasonographic indices that may predict the outcome in two cases with a prenatal diagnosis of VGAM. The indices included mapping of intracranial feeding arteries, assessment of the width of the straight sinus, assessment and measurement of flow in the straight sinus, existence of 'steal' retrograde aortic flow, and the appearance of high-output cardiac state. By using these prenatal ultrasonographic parameters, fetal outcome may be predicted and appropriate management decided upon.

Natural autoantibody to MUC1 is a prognostic indicator for non-small cell lung cancer.

A great deal of attention has been focused on the antitumor effects of anti-MUC1 humoral and cellular responses. We examined whether anti-MUC1 antibody is present in patients with lung cancer, and evaluated its prognostic value. Serum was obtained from 30 patients with nonresectable, non-small cell lung cancer (NSCLC) and 60 healthy volunteers. The presence of anti-MUC1 antibody was determined by enzyme-linked immunosorbent assay. The patients were observed for a median follow-up time of 54.0 mo. Overall survival was estimated by the Kaplan-Meier method. Multivariate analyses were performed using the Cox proportional hazards regression model. Anti-KL-6/MUC1 antibody levels of the patients were significantly lower than those of normal individuals (p < 0.001). One-year survival rate of patients with high concentrations of anti-KL-6/MUC1 antibody was significantly higher than that of patients with low levels of anti-KL-6/MUC1 antibody (90.9% versus 21.1%, p < 0.001). Anti-KL-6/MUC1 antibody status was most strongly correlated with mortality, followed by lymph node status and albumin levels, whereas sex, serum lactate dehydrogenase (LDH), and carcinoembryonic antigen (CEA) levels, and metastasis status did not correlate with mortality. These preliminary results indicate that the degree of decrease in antibody level may be associated with a patient's prognosis.
