Prognostic scoring systems for risk assessment in myelodysplastic syndromes.

Clinical heterogeneity complicates therapy planning and makes it difficult to evaluate clinical trials in myelodysplastic syndromes (MDS). Thus, the development of a prognostic classification of MDS is of major clinical relevance, especially when considering the advanced age of most patients and the aggressiveness of the treatment modalities available. This review summarises the results of different studies focusing on prognostic factors in MDS and describes the relative advantages of the prognostic scoring systems that have been recently developed. This paper also discusses the prognostic factors of particular subtypes of patients. The percentage of marrow blasts, cytogenetic pattern and number and degree of cytopenias are the most powerful prognostic indicators in MDS. Although some limitations are evident, the recently developed scoring systems, and particularly the International Prognostic Scoring System, are extremely useful for predicting survival and acute leukaemic risk in individuals with MDS and should be incorporated into the design and analysis of therapeutic trials in these disorders. A risk-adapted treatment strategy is now possible and highly recommended for MDS patients.

Prognostic value of circulating soluble E-selectin concentrations in node-negative breast cancer patients.

Several studies have suggested that endothelial cells participate in tumor development. Soluble E-selectin (sE-selectin) is specifically released by activated endothelial cells, and its serum concentration can be considered a marker of endothelial activation. In this study, we assessed the prognostic value of sE-selectin concentrations in node-negative breast cancer patients. Serum sE-selectin concentrations were measured by an ELISA method prior to surgery in 456 node-negative breast cancer patients. We analyzed also tumor size (TS), histoprognostic grading, and steroid hormone receptor status. The mean sE-selectin concentration was 24.9 +/- 15.0 ng/ml. The sE-selectin concentrations were mildly correlated with the TS but not with the other factors. For prognostic analyses, the median follow-up duration was 7.5 years. The cutoff sE-selectin concentration used was 40 ng/ml. In overall survival studies, univariate analyses demonstrated a prognostic value of sE-selectin, TS, and histoprognostic grading, and multivariate analyses demonstrated a prognostic value of sE-selectin and TS. For disease-free survival, univariate and multivariate analyses demonstrated a prognostic value of sE-selectin and TS. sE-selectin concentration is an easily measurable and strong prognostic factor in node-negative breast cancer patients. These results provide further evidence for the role of adhesion molecules expression by endothelial cells in tumor progression.

General and specific prognostic factors of early gastric carcinoma treated with curative surgery.

BACKGROUND/AIMS: In Western countries as well as in Japan, the percentages of early gastric cancer (EGC) have been increasing. This study was performed to clarify the general and specific prognostic factors of EGC. METHODOLOGY: General prognostic factors were evaluated in 601 EGC patients treated with curative surgery, including those who died of unrelated causes, and specific prognostic factors were evaluated in 471 EGC patients, excluding those dying of unrelated causes, using univariate and multivariate analysis. RESULTS: The overall 5- and 10-year survival rates in the EGC patients were 86.7% and 76.6% respectively. In all 601 patients, including those who died of other causes, general prognostic factors, according to multivariate analysis, were sex, age, primary malignant diseases other than the original EGC, depth of invasion, and lymph node metastasis. The specific prognostic factor was lymph node metastasis with a risk ratio of 18.6-fold against patients without lymph node metastasis, according to multivariate analysis. CONCLUSIONS: The worst prognostic factors in all EGC patients were male sex, age 60 years and over, presence of primary malignant disease other than original EGC, submucosal cancer, and lymph node metastasis. Lymph node metastasis was specifically related to EGC recurrence. Thus, lymph node dissection is indispensable for the treatment of early gastric cancer, and the surveillance of other organs or the residual stomach for primary malignancy is particularly important after surgery.

Tumour markers CEA and CA 15-3 as Prognostic factors in breast cancer--univariate and multivariate analysis.

Tumour markers are putative prognostic indicators for patients with breast cancer, but have not been elevated independently by multivariate analysis in a large patient number. In 550 patients with breast cancer without known metastases the levels of the serum tumour markers CEA und CA 15-3 were determined preoperatively and during follow-up. The prognostic relevance of these markers for recurrence (n = 128/487) and death of disease (n = 55/550) was evaluated in relation to established prognostic factors. In univariate analysis tumour size, lymph nodes, histological grading, age, hormone receptors, preoperative value of CEA (cut-off 2 ng/mL) and CA 15-3 (cut-off 25 U/mL) and their decrease of more than 33% within seven months after operation were significant for relapse. The results for death of disease were similar except for age. In multivariate analysis tumour size, lymph nodes and decrease of CEA > 33% (p < 0.001) were independent prognostic factors for recurrence. For overall survival tumour size, lymph nodes, histological grading and preoperative levels of CEA > or = 2 ng/mL (p = 0.038) and of CA 15-3 > or = 25 U/mL (p = 0.007) were independent prognostic factors. Pre- and postoperative values of the tumour markers CEA und CA 15-3 are strong independent prognostic factors for relapse and survival in breast cancer patients.

Prognostic factors of diffuse proliferative lupus nephritis.

BACKGROUND: Diffuse proliferative lupus nephritis (DPLN) is the most severe form in lupus nephritis. PATIENTS AND METHODS: We retrospectively analyzed 90 DPLN patients who were confirmed by kidney biopsy and treated at least for 12 months to compare the effectiveness of treatment modalities and to investigate the prognostic factors of DPLN. The patients were categorized to intravenous cyclophosphamide pulse (CY) group and oral corticosteroid (with/without cytotoxic drug, PO) group. RESULTS: When the CY group (69 patients) and PO group (21 patients) were compared, there were no differences between two groups in sex, age, histologic chronicity index (CI, 4.55 vs 3.76; CY vs PO, respectively), mortality rate (4.3% vs 0%), remission rate of nephritis (at 3-year 59. 1 % vs 75.5%), renal survival rate (at 5-year 88.0% vs 91.7%) and complications of treatment, but significant differences in the frequency of nephrotic syndrome (66.7% vs 33.3%) and initial azotemia (30.4% vs 0%). histologic activity index (7.14 vs 4.33) and relapse rate (2.9% vs 42.9%). When the remission group (49 patients) and non-remission group (41 patients) were compared, CI, initial renal insufficiency, male sex and the duration of nephritis were the prognostic factors for remission in univariate analysis, and male sex (OR 10.99) and CI (OR 9.89) in multivariate analysis. When the remission group (35 patients) and non-remission (34 patients) group were compared in the CY group, CI was the prognostic factor in univariate analysis, and CI (OR 8.63) and male sex (OR 5.54) in multivariate analysis. The initial renal insufficiency (OR 12.74) and male sex (OR 7.99) were the prognostic factors for renal survival. The renal survival rate was 100% in remission-induced patients. CONCLUSION: We conclude that CI, male sex, initial renal insufficiency were the prognostic factors of DPLN, and treatment with oral corticosteroid could induce remission in patients who had mild histologic and clinical features. Therefore it would be necessary to evaluate the prognostic factors before the selection of treatment modality.

[Primary small-cell bronchial cancer: value of serum tumor markers in the prognostic evaluation].

TUMOR MARKERS: We reviewed the biomedical literature searching for the most well-documented serum markers with prognostic value independent of the usual radioclinical and histological parameters of small cell lung cancer. RELATIVE PROGNOSTIC VALUES: Neuron specific enolase (NSE) would have a pretherapeutic prognostic value better than LDH (lacto-dehydrogenase) and perhaps better than serum sodium, biocarbonates, and uric acid. The superiority of NSE over serum albumin remains to be proven. Although there are only a few reports, TK (thymine kinase), TPA (tissue polypeptide antigen), Cyfra 21-1 and/or IL-2 (interleukin-2) secretion might have better pretherapeutic prognostic value than NSE. We also found that iterative blood assays to follow therapeutic effects in patients with small-cell lung cancer have not been proven to provide independent prognostic information. CONCLUSION: As medical laboratory resources must be concentrated on priority exploitable assays, the currently available data would suggest that it is not necessary to routinely measure serum tumor markers, and in particular NSE, for the prognostic evaluation of small-cell lung cancer patients.

Pathologic prognostic factors in esophageal squamous cell carcinoma: a follow-up study of 74 patients with or without preoperative chemoradiation therapy.

One of the primary goals of pathologic examination of esophageal squamous cell carcinoma resection specimens is to provide information regarding morphologic features which can help prognosticate and guide management of affected patients. The purpose of this study was to determine the prognostic utility of a variety of histopathologic prognostic factors in patients with esophageal squamous cell carcinoma with and without preoperative chemotherapy and radiotherapy (chemrad). Multiple clinical and histologic features such as peri-tumoral lymphocytic infiltrate, Crohn's-like lymphoid reaction, degree of residual tumor, mitosis per 1000 cells, tumor differentiation, lymphatic/vascular invasion, perineural invasion, desmoplastic reaction, and tumor growth pattern were evaluated in patients with (53) and without (21) preoperative chemrad and correlated with survival (mean follow-up, 25 mo). Data were analyzed for the entire cohort and for each separate treatment group by univariate and multivariate analysis. Patients who received chemrad showed no significant survival benefit (hazard ratio = 2.5, P = .10). In the whole cohort of patients, higher pathologic stage (P = .04), poor tumor differentiation (P = .003), increased mitotic count (P = .005), perineural invasion (P = .01), lymphatic/vascular invasion (P = .002), tumor size (P = .05), and absence of a Crohn's-like lymphoid reaction (P = .05) were significantly associated with poor survival by univariate analysis. In multivariate analysis, poor tumor differentiation (P = .005), high mitotic count (P = .01), and vascular invasion (P = .03) were important prognostic features, independent of pathologic stage, for the entire cohort. In the chemrad group only, tumor size (in patients with macroscopic residual tumor) (P = .05), lymph node metastasis (P = .03), mitotic count (P = .01), and lymphatic/vascular invasion (P = .02) were significant prognostic indicators by univariate analysis. Upon multivariate analysis, only lymphatic/vascular invasion (P = .02) and mitotic rate (P = .01) were independent predictors of survival. In the nonchemrad group, only tumor differentiation was significant by both univariate (P = .008) and multivariate analysis (P = .03). The differences in pathologic prognostic factors between chemrad and nonchemrad treated cases suggests that chemrad has a significant effect on the biologic properties of these tumors.

[Value of Führman's nuclear grade: comparison with other prognostic factors of renal epithelial tumors].

OBJECTIVE: To assess the prognostic value of Führman's nuclear grade and to compare it to various clinical and histological prognostic factors of renal carcinomas. PATIENTS AND METHOD: Single-centre retrospective study of 102 patients operated for renal tumours between January 1985 and December 1990 (mean follow-up: 8.2 years). Prognostic assessment was studied from survival curves. RESULTS: The prognostic factors most closely correlated with survival were, in decreasing order, metastatic invasion, nuclear grade, stage of local extension and lymph node invasion. A significant (p < 0.01) survival difference was only observed between Führman grade 2 and grade 3 tumours. This difference was accentuated (p < 0.001) when grade 1 and 2 tumours were compared to grade 3 and 4 tumours. Führman's nuclear grade is independent of the side affected, the tumour volume, its multifocal nature, microscopic venous invasion and metastatic invasion at the time of diagnosis. Führman's nuclear grade is correlated with invasion of fat, the presence of a contingent of eosinophilic cells, stage of local extension, lymph node invasion and the subsequent development of metastases. CONCLUSION: This study confirms the importance of Führman's nuclear grade among the various prognostic factors of renal carcinomas and quantifies its value with respect to other prognostic factors.

Cathepsin B, a prognostic indicator in lymph node-negative breast carcinoma patients: comparison with cathepsin D, cathepsin L, and other clinical indicators.

New prognosticators are needed for breast cancer patients after the initial surgical treatment to make therapeutic decisions that ultimately will affect their DFS. These consist of specific proteolytic enzymes including lysosomal endopeptidases. In this study, the activity and protein concentrations of cathepsins (Cats) D, B, and L were measured in 282 invasive breast tumor cytosols. These potential biological prognostic indicators were compared with other histopathological parameters, such as tumor size, lymph node involvement, tumor-node-metastasis stage, histological grade, DNA analysis, and steroid receptors. CatD protein concentration correlated with lymph node involvement. CatB and CatL levels correlated significantly with Scarf-Bloom-Richardson histological grade and were also higher in estrogen-negative tumors, and CatB was higher in larger tumors. As prognostic markers, CatB concentration was significant for increased risk for recurrence in the entire patient population and specifically also in lymph node-negative patients as follows: high CatB concentration (above 371 micrograms/g) in tumor cytosols was significant (P < 0.00) for high risk of recurrence but was of only borderline prognostic significance (P < 0.06) for overall survival of all patients. In lymph node-negative patients, CatB (above 240 micrograms/g, P < 0.003) was highly significant for recurrence-free survival, followed by CatL (above 20 micrograms/g, P < 0.049) and CatD (above 45 nmol/g, P < 0.044) concentrations. For overall survival of node-negative patients, only CatB was a significant (P < 0.014) prognosticator. We conclude that CatB is useful as a prognostic indicator in lymph node-negative patients. This suggests that selective adjuvant therapy should be applied in this lower risk group of patients when high levels of CatB are determined.

Analysis of clinicopathologic prognostic factors for 157 uterine sarcomas and evaluation of a grading score validated for soft tissue sarcoma.

BACKGROUND: Uterine sarcomas (US) are rare and carry a poor prognosis characterized by high rates of local recurrence and metastasis. The aim of this study was to test, for what the authors believe was the first time with US, the prognostic impact of the histologic grade validated by the French Federation of Anticancer Centers (FNCLCC) for soft tissue sarcomas (STS). The grade is the sum of the scores allocated for three major histologic criteria: tumor differentiation, mitotic count, and tumor necrosis. Other histologic and clinical factors were tested as well. METHODS: The study included 157 patients in whom 78 leiomyosarcomas (LMS), 52 malignant mixed müllerian tumors (MMMT), and 27 endometrial stroma sarcomas (ESS) were documented. RESULTS: The median follow-up was 54 months (range, 6-230 months). The median OS and EFS were 33 and 13 months, respectively. The FNCLCC grade validated in soft tissue sarcomas was not a prognostic factor for survival or relapse for any of the US histologic subtypes. For LMS, stage and mitotic count were the only factors that had an influence on survival and relapse. For MMMT, stage and age were the only prognostic factors, and none of the histologic criteria impacted on the outcome. For ESS, the grade defined by Norris and Taylor was an important prognostic factor, particularly for survival. CONCLUSIONS: The FNCLCC grading score could not be used as a prognostic indicator for uterine sarcomas. The diagnosis of US is in itself an unfavorable prognostic factor, except when the diagnosis is low grade ESS.

[The prognostic significance of 99mTc-MDP breast scintigraphy. A comparison with histological and molecular parameters].

INTRODUCTION: Breast scintigraphy (BS) with the bone-seeking agent 99mTc-medronate (MDP) can be usefully combined with mammography to diagnose and characterize questionable breast lumps. However this radiotracer does not seem to provide any further prognostic information about breast cancer. Therefore we investigated the prognostic yield of MDP-BS searching for correlations between scintigraphic findings and the major biological and histologic parameters. MATERIALS AND METHODS: We retrospectively analyzed a series of 44 primary breast cancers. All patients had undergone 99mTc-MDP bone scan for preoperative staging, as well as conventional breast imaging. We statistically compared the cancer/background ratio (c/b index) with lesion histotype, diameter, grading, and the tissue concentrations of steroid receptors, cathepsine D, type 1 timidine kinase, pS2 and p53 proteins. RESULTS: MDP-BS failed to depict 11 of 44 lesions (O 0.5-2 cm), detected 7 of 16 mammographically questionable lesions and correctly visualized the two multifocal cases. Also, MDP-BS depicted no metastatic axillary lymph nodes. We found no statistically significant correlation between the c/b index and the prognostic markers. DISCUSSION AND CONCLUSIONS: Differently from BS with 99mTc-MIBI, 201T1, 18F-FDG, 111In-OCT and radiolabeled estrogens and despite its good overall accuracy, MDP-BS appears to have no prognostic role. In fact, despite the well-known capability of soft tissue lesions to take up the tracer, MDP tumor trapping seems to depend mainly on the increased permeability of neovessels and on interstitial space enlargement. Few reports are available in the literature on the correlation between in vivo MDP uptake by the breast cancer and prognostic parameters. Thus, we tested possible correlations between the amount of MDP taken up by the breast cancer, histologic features and cell concentrations of some major biomarkers. The lack of any statistical significance is in agreement with the theory, and confirms the little prognostic value of MDP-BS. Nevertheless, further trials are warranted on larger series of cases to validate our personal findings.

Prognostic value of the cyclin-dependent kinase inhibitor p27Kip1 in gastric cancer.

In the present study, the expression and prognostic role of p27 were immunohistochemically investigated in 413 curatively resected gastric carcinomas. Strong p27 expression in more than 50% of the tumour cells could be detected in 57.4% (n = 237) whereas 42.6% of the tumours (n = 176) only showed p27 expression in less than 50% of the tumour cells. No significant correlation could be observed between p27 expression and the prognostic parameters pT category, pN category, blood and lymphatic vessel invasion as well as with tumour histology. Concerning other cell cycle associated proteins, p27 expression was inversely correlated with p21 expression, however, there was no correlation either with cyclin D1 and cyclin E or with expression of p53, bcl-2 and tumour cell proliferation. Univariate survival analysis revealed a poorer prognostic outcome for patients with tumours expressing p27 in more than 50% of the tumour cells (p < 0.049). However, by multivariate analysis, this prognostic influence of p27 could not be verified as independent from the known prognostic parameters of the pTNM-system (p < 0.325). The present data on 413 curatively resected gastric carcinomas suggest, that expression of p27, analyzed alone or in combination with multiple cell cycle regulatory proteins, has no prognostic value in gastric cancer.

Postoperative radiotherapy in endometrial carcinoma: analysis of prognostic factors in 440 cases.

PURPOSE: The aim of this study was to determine the prognostic factors influencing overall, disease-free and local recurrence-free survival in patients treated postoperatively with adjuvant radiotherapy for endometrial carcinoma. METHODS: The records of 440 patients with endometrial carcinoma treated by postoperative radiotherapy between January 1985 and June 1997 were reviewed retrospectively. All patients received postoperative external radiotherapy with 1.8-2.0 Gy daily fractions up to 36-68 Gy (median 54 Gy). Intracavitary brachytherapy was applied to 61.8% of the cases. Survival analysis was performed using the Kaplan-Meier method. The log-rank test was used for univariate analysis and the Cox regression model for multivariate analysis. RESULTS: Median age of the patients was 57 (range: 35-83). Histologically 80.2% were adenocarcinoma, 5.7% adenosquamous carcinoma, 5.2% clear-cell carcinoma and 4.3% serous papillary carcinoma. The distribution by stages were: 62.2% Stage I, 20.0% Stage II, 14.9% Stage III, 2.8% Stage IV. Median follow-up time was 53 months (7-173 months). Total failure rate was 15.2% with 2.7% of patients having only local failure, 2.0% local and distant failure and 10.5% distant failure only. Five-year overall, disease-free and local recurrence-free survival rates were 81.6%, 80.7% and 94.6%, respectively. According to univariate analysis prognostic factors influencing disease-free survival were histologic type (p=0.0067), histologic grade (p=0.0015), stage (p<0.0001), myometrial invasion (p<0.0001), peritoneal cytology (p=0.0013) and cervical involvement (p=0.0106) while the prognostic factors affecting local recurrence-free survival were stage (p=0.0277), myometrial invasion (p=0.0054), peritoneal cytology (p=0.0427). According to multivariate analysis prognostic factors influencing disease-free survival were histologic type (p=0.0194), myometrial invasion (p=0.0021), and histologic grade (p=0.0303) while the only prognostic factor influencing local recurrence-free survival was myometrial invasion (p=0.0241). CONCLUSION: Radiotherapy is a highly effective adjuvant treatment providing an excellent locoregional control rate and it should be continued for patients with unfavorable prognostic factors.

Prognostic significance of young age in breast cancer.

BACKGROUND: Breast carcinoma is relatively uncommon in younger women and whether or not young age at diagnosis is an adverse prognostic factor in this disease has been controversial. Our aim in this report is to determine whether the histopathologic features and outcome in young and old are different, and whether age is a prognostic factor for relapse. METHODS: A retrospective study of consecutive 281 stage I or II breast carcinoma patients who had modified radical mastectomy was carried out. The patients with a median follow-up period of 45 months were divided two groups according to their ages. The histopathological features and survival of Group 1 and Group 2 were compared with each other. Univariate and multivariate prognostic factor analysis for relapse were carried out. RESULTS: The patients in Group 1 (younger than 35 years of age) had the worst histopathological features related to the prognosis than those in Group 2 and the difference between the two groups was statistically significant. Whereas the rates of 5-year overall survival were 65% in Group 1 and 98% in Group 2 (P < 0.05), the rates of 5-year relapse-free survival were 40% and 80%, respectively (P < 0.05). In univariate analysis of all patients, pathologic tumour size, pathologic axillary status, number of metastatic lymph nodes, pathologic stage, age, lymphatic vascular invasion were statistically significant factors associated with relapse. Multivariate analysis demonstrated that number of metastatic nodes (risk ratio RR:4.3 in more than three nodes) and age (RR:3.6 in Group 1) were the most important independent prognostic factors for relapse. In the patients without axillary involvement, both of univariate and multivariate analysis revealed that pathologic tumour size (RR:5.1 in pT(2)) and age (RR:4 in Group 1) were the independent prognosticators for relapse. CONCLUSIONS: Young patients with breast cancer had the worst histopathological features and the worst survival than their older counterparts. Age was an independent significant prognostic factor for relapse.

Prognostic significance of p27KIP1 protein and ki-67 growth fraction in non-small cell lung cancers.

We immunohistochemically examined specimens of 215 surgically resected non-small cell lung cancers (NSCLCs) for p27KIP1 protein (p27) expression and the growth fraction determined by the Ki-67 labeling index (LI). The NSCLCs analyzed showed considerable heterogeneity in both p27 and Ki-67 LIs; 25 of 207 (13%) lacked p27 expression (p27 LI < 5%), and 116 of 215 (54%) showed a high Ki-67 LI (>30%). The p27 LI was not significantly associated with the Ki-67 LI. A chi2 test showed that loss of p27 expression was inversely correlated with smoking (P = 0.01) and that a high Ki-67 LI was significantly associated with male gender, squamous cell carcinoma histology, and smoking (P < 0.0001 each). Prognostic values of p27 and Ki-67 expression were evaluated in 109 tumors of postsurgical pathological stages I and II. Patients with tumors lacking p27 expression survived for a significantly shorter time than patients with tumors expressing p27 (5-year survival rates, 38% and 68%, respectively; P = 0.02). Patients with tumors having a high Ki-67 LI survived for a significantly shorter time than patients with tumors having a low Ki-67 LI (5-year survival rates, 48% and 78%, respectively; P = 0.005). Multivariate analysis showed that loss of p27 expression tended to be an unfavorable prognostic factor (P = 0.054), whereas a high Ki-67 LI was a significant and independent unfavorable prognostic factor (P = 0.004). When analyzed by cell types, loss of p27 expression was a significant and independent unfavorable prognostic factor in squamous cell carcinomas (P = 0.01), whereas a high Ki-67 LI was a significant and independent unfavorable prognostic factor in nonsquamous cell carcinomas (P = 0.007). We further evaluated the importance of p27 expression in clinical outcome in combination with the Ki-67 LI and ras p21 protein (ras) expression, which we previously reported as an important prognostic factor in NSCLCs. Patients with tumors lacking p27 expression and having a high Ki-67 LI survived for a significantly shorter time than those with tumors expressing p27 and having a high Ki-67 LI (5-year survival rates, 17% and 52%, respectively; P = 0.003). Patients with p27-negative and ras-positive tumors survived for a significantly shorter time than those with both p27- and ras-positive tumors (5-year survival rates, 0% and 38%, respectively; P < 0.0001). These results indicate the pivotal roles of p27 and Ki-67 expression in the clinical outcome of NSCLCs.

Combined prognostic importance of CA 125, histopathologic grade and DNA-index in advanced ovarian cancer.

PURPOSE: To analyse the possible prognostic importance of a combination of serum CA 125 levels, tumor cell DNA distribution and histopathologic grade in patients with epithelial ovarian cancer. METHOD: The study included 41 patients with ovarian cancer stages II-IV. CA 125 was measured before the start of chemotherapy and after every course. The DNA distribution was analysed by flow cytometry in biopsy specimens from the primary tumour. The histopathologic grading was performed according to WHO criteria. RESULTS: The CA 125 level was of major prognostic significance. All patients with an abnormal value (> 35 U/ml) after three courses died within 16 months. The DNA distribution did not add significant prognostic information, but the histopathologic grade was of significant prognostic importance as investigated by Cox analysis. CONCLUSION: CA 125 is an important prognostic marker in epithelial ovarian cancer. The value after three courses of chemotherapy is significant. The histopathologic grade adds further prognostic information.

Prognostic significance of CyclinD1 and E-Cadherin in patients with esophageal squamous cell carcinoma: multiinstitutional retrospective analysis. Research Committee on Malignancy of Esophageal Cancer, Japanese Society for Esophageal Diseases.

BACKGROUND: Although many molecular biologic molecules have been analyzed for their prognostic influence on patients with esophageal cancer, previous studies have not been able to raise statistically significant prognostic factors. STUDY DESIGN: Immunohistochemical analysis of CyclinD1 expression and E-Cadherin expression was performed retrospectively in 416 esophageal squamous cell cancer patients who underwent curative resection of esophageal cancer at 10 major surgical departments in Japan, where more than 30 esophagectomies are performed in a year. The prognostic impact of these molecules and their relationship to clinicopathologic data of the patients were evaluated. RESULTS: Univariate analysis revealed that pN (pTNM), pT (pTNM), CyclinD1 expression, and E-Cadherin expression were significant prognostic factors, and multivariate analysis revealed that pN (risk ratio (RR) 2.19), pT (RR 3.35), CyclinD1 (RR 1.42), and E-Cadherin (RR 0.71) were significant prognostic factors. Combination analysis of these genes revealed that E-Cadherin-preserved and CyclinD1-negative patients had the best prognosis; E-Cadherin-reduced and CyclinD1-positive patients had the worst prognosis. CONCLUSIONS: Increased CyclinD1 expression and reduced E-Cadherin expression were significant prognostic factors in patients with esophageal squamous cell carcinoma.

Prognostic factors in stage I ovarian carcinoma.

Most studies on prognostic factors in stage I ovarian carcinoma have been hampered by a relative small number of patients included. In this study we identified the most important independent clinical and pathological prognostic factors in stage I epithelial invasive ovarian carcinoma in a large data base of 1545 patients with stage I epithelial ovarian carcinoma. The patients were treated in 6 different countries but were analysed in the same way. Because of the increasing use of endoscopy to remove possibly malignant cysts and the reports on rapid spread of ovarian carcinoma in the peritoneal cavity after laparoscopic removal of ovarian cancers, special attention was made to the presence and timing of the cysts before or during surgery. The multivariate analyses identified degree of differentiation as the most powerful prognostic indicator of disease-free survival, followed by rupture before surgery, rupture during surgery, International Federation of Gynaecology and Obstetrics (FIGO) 1973 stage and age. When the effects of these factors were accounted for, none of the following were of prognostic value for disease-free survival: histological type, dense adhesions, extracapsular growth, ascites, FIGO stage 1988, and size of tumour. In conclusion, degree of differentiation was the most powerful prognostic indicator in Stage I ovarian cancer and should be used when deciding therapy in clinical practice. We also strongly advocate the inclusion of degree of differentiation in a new FIGO classification of stage I ovarian carcinoma. In addition, rupture before and during surgery, FIGO Stage 1973 (Ib versus Ia) and age were shown to be independent prognostic factors. Hence, every effort should be made to avoid rupture during primary surgery of malignant ovarian tumours confined to the ovaries.
