[Prognostic factors in breast cancer].

Prognostic factors are clinical and pathological features that give information in estimating the likely clinical outcome of an individual suffering from cancer. The author gives a short review of the most important prognostic factors in breast cancer. 376 breast cancer cases of a ten year interval in a county hospital are summarized. Traditional clinico-pathological parameters i.e. TNM and steroid receptor status are discussed. The more common karyotipic, oncogene and tumor suppressor gene alterations are outlined in the study. Methods for their detection are presented and their value in prognostication is reviewed. Emphasis was laid on steroid receptors, c-erpB-2, p53 and bcl-2 alterations. Genes responsible for heritable forms of increased breast cancer risk are briefly reviewed.

Prognostic factors in stroke.

Prognostic factors in 137 patients with acute ischaemic infarction of the cerebral hemisphere were examined in a prospective study with particular reference to acute mortality, delayed mortality and the ability to regain independent living. Adverse factors in the examination on admission to hospital with regard to all these aspects were found to be a reduction of the level of consciousness to any degree and paralysis of conjugate gaze. A severe hemiplegia and advancing age indicated a bad prognosis for delayed mortality and severe disability in survivors, but did not affect acute mortality. At three weeks after the onset, inability to walk unaided, a useless hand and or urinary incontinence was associated with an increased probability of death in the next few months and of failure to regain independence in the survivors. These adverse factors appeared to correlate with infarction extending beyond the middle cerebral artery territory, severe brain swelling and recent occlusion of the internal carotid artery.

Sex therapy for erectile dysfunction: characteristics of couples, treatment outcome, and prognostic factors.

Outcome and prognostic factors were studied in 36 couples who entered sex therapy because of the male partners' erectile dysfunction. Treatment was completed by two thirds. Noncompletion was associated with lower socioeconomic status, the female partner having a history of psychiatric treatment, pretreatment poorer motivation of the male partner, poor communication in the general relationship, and less sexual pleasure experienced by the female. A positive treatment outcome occurred in 69.4%, and was associated with better pretreatment communication and general sexual adjustment, especially the female partner's interest and enjoyment of sex, absence of a positive psychiatric history in the female partner, and a couple's early engagement in homework assignments. Results highlight important aspects of the initial assessment, indicate couples for whom the initial phase of treatment should be prolonged and modified or an alternative approach considered, and have implications for assignment of couples to treatment groups in evaluative studies of therapy.

[Results of kidney transplantation in Leiden, 1966-1994, and prognostic factors].

OBJECTIVE: Evaluating prognostic determinants and results of renal transplantation. DESIGN: Descriptive study. SETTING: Leiden University Hospital, The Netherlands. METHODS: Follow-up of all 1289 patients who had a kidney transplantation in Leiden University Hospital between March 1966 and December 1994. The following determinants were investigated: age and sex of donors and recipients. HLA matching, type of immunosuppression, presensitization, presence of diabetes mellitus, and living or post-mortem donor. RESULTS: Renal transplantation was very successful during the first few years, one-year graft survival dropped to 50% during the second decade and gradually increased to almost 90% during the last years. 5-year and 10-year graft survival were 65% and 50% respectively. The mean age of recipients increased from 32.8 years to 45.7 years, that of donors from 24.9 to 37.9 years. Duration of dialysis before transplantation increased from 19.7 months to 35.7 months. The introduction of cyclosporine and matching on the HLA-DR locus were responsible for better transplantation results. Other favourable prognostic factors were absence of diabetes mellitus, absence of panel reactive antibodies, kidney from a living donor, male donor and donor age between 20 and 50 years. CONCLUSION: Both short term and long term results of renal transplantation improved in spite of a strong increase of mean donor age and mean recipient age and an increase of co-morbidity of the recipients. Introduction of HLA-DR matching and cyclosporine immunosuppression contributed to better graft survival.

Prognostic factors in colorectal cancer.

Prognostic factors should always be taken into consideration before planning treatment. As reported in the literature, and also in our experience, the extent of intestinal wall invasion and the lymph node status must be considered the most important prognostic factors. In the present paper the data from literature are reported and the impact of biologic factors is analyzed. We are convinced that in the future the biological factors of the tumor as well as of the patient should be considered in planning treatment.

[Renal cell carcinoma before the age of 40: prognostic factors].

OBJECTIVE: To study the prognostic value of tumour diameter, TNM stage, Führman's nuclear grade and CD44 adhesion molecule expression in renal cell carcinoma (RCC) before the age of 40 years. MATERIAL AND METHODS: Nineteen patients under the age of 40 (12 males and 7 females; mean age 30.8 years), undergoing total nephrectomy for RCC were included in this study. Tumour diameter, TNM 1997 stage, and Führman's nuclear grade were defined for each tumour. Standard CD44 adhesion molecule (CD44H) expression was evaluated semiquantitatively by immunohistochemistry on each tumour. The prognostic value of the various variables was determined by Mann-Whitney and Chi-square tests and survival analysis was performed by the Kaplan-Meier method. RESULTS: Six patients (31.5%) died from their cancer with a mean follow-up of 81.4 months. Mean tumour diameter was 9 +/- 4.5 cm. Tumours were Führman I/II in 4 cases, Führman III/IV in 15 cases, T1/T2 in 14 cases and T3/T4 in 5 cases. CD44H expression was high (> or = 20%) in 9 cases (47.3%). The prognostic factors identified in this study were: tumour stage (p = 0.01), grade (p = 0.04), venous extension (p = 0.001) and CD44H overexpression (p = 0.003). CONCLUSION: Prognostic factors of renal cancer in patients under the age of 40 years do not appear to be different from those of older patients. The prognostic factors identified in this study must be validated by multicentre studies based on larger populations.

Cutaneous melanoma: prognostic factors.

BACKGROUND: Recent data have changed our views of prognostic factors in cutaneous melanoma. While some newer methods have yielded better prognostic information, some insights have evolved as a result of large-scale population-based analyses. METHODS: We review current data on several different prognostic factors and divide these factors according to their application in localized primary melanoma or metastatic melanoma. For each prognostic factor, the level of evidence supporting its use and its applicability to clinical practice are considered. RESULTS: For localized primary melanoma, the dominant predictors of survival include lesion thickness, ulceration, and lymph node involvement. Factors such as age, sex, anatomic location, and satellite/in-transit lesions are important in localized melanoma. Factors currently being investigated are tumor vascularity, vascular invasion, mitotic rate, tumor regression, and tumor-infiltrating lymphocytes. For metastatic melanoma, the most important prognostic factors are site of metastases and the presence of elevated serum lactic dehydrogenase. The value of these prognostic factors to clinicians caring for melanoma patients is discussed. CONCLUSIONS: A better understanding of prognostic factors in cutaneous melanoma has evolved over the last decade, allowing oncologists to provide appropriate treatment for their patients. Many of the prognostic factors are interrelated. In the near future, it is expected that several molecular genetic factors will provide more insight into the prognosis of patients with melanoma.

Prognostic factors in clinical trials.

Prognostic factors define the study population, help formulate the study objectives, and influence the treatment strategies. They must be accounted for in the study analysis to obtain valid estimates of the treatment differences and to evaluate results across studies. The causal relationship between a prognostic factor and the study endpoint can only be established through prospective randomized study designs. Potential factors discovered through retrospective analysis must be verified to establish their validity. Using such factors prematurely to select patient population and treatment strategy for a new study will not establish the validity of the potentially important factor.

Synovial sarcoma of the extremities: prognostic factors for 20 nonmetastatic cases and a new histologic grading system with prognostic significance.

PURPOSE: To evaluate 20 cases of nonmetastatic synovial sarcoma of the extremities regarding prognostic factors, and to propose a histologic grading system with prognostic significance. METHODS: The cases of 20 patients (14 females and 6 males) with nonmetastatic synovial sarcomas of the extremities treated between 1985 and 1998, were retrospectively evaluated regarding prognostic factors. A histologic grading system with prognostic significance is proposed. RESULTS: The mean follow-up period was 48.4 months (range, 16-116 months). There was local recurrence in 3 cases (15%), microscopic surgical margin being the only prognostic factor identified. Seven patients (35%) died of the disease in a mean postoperative period of 31.7 months (range, 16-53 months), all with pulmonary or brain metastasis. The survival rate was 65% in 48.4 months of follow-up. CONCLUSION: The unfavorable prognostic factors identified regarding survival were high histologic grade, tumors proximal to the knee or elbow, and spontaneous tumor necrosis over 25%. Local recurrence did not have influence on survival in this study. The presence of mast cells appears to have a positive influence on survival, although statistical significance was not reached (P = 0.07). The oncologic and functional result was good in 6 cases (30%), regular in 7 (35%), and poor in 7 cases (35%).

[Transitional carcinoma of the bladder. Evaluation of prognostic factors].

This study evaluates prognostic factors in 25 patients with transitional cell carcinoma (TCC) of the bladder with a minimum follow up of two years. Histologically there were 12 patients with grade I tumors according to the Mostofi's classification, 10 patients with grade II lesions and 3 grade III. The course of the grade I and II tumors was similar and the grade III worse. According to stage, there were 11 patients stage 0, 8 stage A, 3 stage B and 3 stage C. Patients with all stages recurred but only those with stage B and C died of their disease. In 18 patients the expression of the beta subunit of HCG and of the blood group isoantigens was demonstrated by immunohistochemistry. There were 8 negative cases and 10 positive for the beta subunit of HCG and 10 negative and 8 positive for the blood group isoantigens. DNA analysis was done with an image analyzer on cytological smears of the urine in the 25 cases after decolorization of the smears and Feulgen staining. There were 5 diploid and 25 aneuploid cases. The DNA malignancy grade was determined with a range between 0.100 and 2.689 and the number of events more than 5c (5N). The presence of HCG, aneuploid tumors, a malignancy grade higher than 0.500 and the presence of events more than 5c were statistically significant unfavorable prognostic factors. The presence of blood group isoantigens was associated with a better evolution of the tumor but did not reach statistical significance.(ABSTRACT TRUNCATED AT 250 WORDS)

Prognostic factors in malignant mesothelioma.

Many prognostic factors have been described in malignant mesothelioma, but only a limited number has been validated by prospective, confirmatory studies. These include performance status, histology, weight loss and leucocyte count. Their value as predictors of patient survival in malignant mesothelioma is limited, as is their role in current clinical practice. At this moment their main importance is their application in clinical studies, which allows a better delineation of the patient group to which the study results can be applied to and a more accurate comparison between different studies. The biological prognostic factors need confirmation by larger prospective trials and should be analysed with respect to the existing prognostic factors. In the future, their use might not be limited to the prediction of the patient survival but direct the development of new therapies and extend to the molecular prediction of tumour response.

Multivariate analysis of prognostic factors in patients with endometrial cancer.

OBJECTIVE: The prognostic factors of endometrial cancer are closely correlated. A multivariate analysis was carried to compare the importance of each factor. METHOD: A multivariate analysis was performed of 19 clinicopathologic prognostic factors obtained from 144 endometrial cancer patients who had been surgically treated in our hospital between January 1971 and December 1993. RESULTS: Significant prognostic factors according to the Kaplan-Meier method were depth of invasion, vascular invasion, nuclear grade, cervical involvement, lymph node metastases, intraperitoneal cytology, serous adenocarcinoma, DNA ploidy, type of hysterectomy and surgery only or combined with chemotherapy or radiotherapy. Multivariate analysis showed that vascular invasion and nuclear grade were more significant than structural grade, histologic subtype or DNA ploidy. CONCLUSION: Multivariate analysis is useful for extracting important recurrent factors from mutually related prognostic factors. Vascular invasion and nuclear grade are singled out as the most useful histologic prognostic factors.

Evaluation of cell proliferation, epidermal growth factor receptor, and bcl-2 immunoexpression as prognostic factors for patients with World Health Organization grade 2 oligodendroglioma.

BACKGROUND: Prognostic factors in oligodendrogliomas are an area of controversy in neuropathology. Although grading and the study of some morphologic variables may be of value as prognostic parameters, the variability of postoperative disease free survival in patients with World Health Organization Grade 2 oligodendroglioma indicates that the biologic behavior of this entity remains unknown. The objective of the current study was to evaluate immunoexpression of the proliferation index (PI), epidermal growth factor receptor (EGFR), and bcl-2 as prognostic factors in patients with Grade 2 oligodendroglioma. METHODS: In a series of 19 cases of pure Grade 2 oligodendroglioma, we assessed the mitotic count, labeling index for MIB-1 and PCNA, and immunoreactivity for EGFR and bcl-2 with semiquantitative parameters and compared these with postoperative disease free survival. Statistical analyses using the Cox-Mantel nonparametric test and Spearman correlation coefficient were used to evaluate the data. RESULTS: Disease free survival was significantly shorter when the MIB-1 PI was > 5% (P = 0.0096) and the PCNA PI was > 9% (P = 0.00011) and when mitoses were observed (P = 0.00004). The paired variables also were found to correlate: MIB-1 versus PCNA (P = 0.04), MIB-1 versus mitotic count (P = 0.0184), and PCNA versus mitotic count (P = 0.0079). In all cases, there was immunoreactivity for EGFR; conversely, all cases were negative for bcl-2 in the cells with an oligodendrocyte phenotype. CONCLUSIONS: The PI was found to correlate with the postoperative disease free survival in patients with Grade 2 oligodendroglioma; therefore, the authors suggest a possible subdivision of Grade 2 oligodendrogliomas into two groups based on the mitotic count and PI.

Results of the cyclophosphamide, doxorubicin, vincristine, prednisolone (CHOP) +/- bleomycin treatment and evaluation of prognostic factors in aggressive lymphomas in Turkey.

Prognostic factors and the results of the cyclophosphamide, doxorubicin, vincristine, prednisolone (CHOP) +/- bleomycin treatment in 93 consecutive evaluable patients with aggressive lymphomas are presented. The overall response rate, excluding 7 patients with primary extranodal lymphoma who were in complete remission after surgery, was 83% with a complete response (CR) rate of 69%. Overall survival (OS) rates of all patients and disease-free survival (DFS) rates of complete responders at 4 years were 52 and 66%, respectively. Almost two thirds of the patients could be given at least 75% of the planned chemotherapy doses. Treatment toxicities were in acceptable limits, only 10% of the patients had grade 3-4 hematological toxicity. Age, performance status (PS), stage, number of extranodal sites (ENS) (< or = 1 vs. > 1), B symptoms, serum LDH levels were evaluated as prognostic factors. Univariate survival analysis yielded stage, ENS and PS as significant prognostic factors for OS (p = 0.0009, p = 0.0028 and p = 0.0155, respectively). Only involvement of more than 1 ENS was strongly associated with low CR (p = 0.0479) and high relapse rates (p = 0.0118), and it was also determined as the only independent prognostic factor for OS in patients younger than 60 (p = 0.0015). A modified age-adjusted prognostic index, including ENS in addition to stage, LDH and PS, was found to be more significant than the original age-adjusted International Prognostic Index (IPI) for both DFS (p = 0.0030) and OS (p < 0.00001). In conclusion, modified age-adjusted index may be a convenient alternative to the original age-adjusted IPI to identify high-risk patients with aggressive lymphomas in Turkey and probably also in other developing countries for experimental intensive regimens.

Prognostic factors for medulloblastoma.

PURPOSE: To evaluate prognostic factors for medulloblastoma. METHODS AND MATERIALS: One hundred and seventy-three consecutive patients with medulloblastoma, treated at King Faisal Specialist Hospital (KFSH) from 1988-1997, were reviewed. Eighty-four percent were children less than 15 years old. From 1988-1994, treatment was at the discretion of the investigator. From 1994-1998, patients entered a single-arm best practice protocol in which, in staged patients, the surgical intent was total resection, standard radiation treatment was defined, and adjuvant chemotherapy was given to a "high-risk" subset. RESULTS: For 150 patients who completed surgical and radiation treatment, the 5-year survival rate was 58%, compared with 0% for 16 patients who were unable to start or complete radiation treatment. For staged patients, the 5-year survival was M0 + M1, 78% and M2 + M3, 21% (p < 0.0001). Other favorable significant prognostic factors were age >14 years and gross cystic/necrotic features in the primary tumor. The size of the primary tumor, the degree of hydrocephalus at diagnosis, the presence of residual tumor in the post-operative CT/MRI, and the functional status of the patient prior to radiation treatment were not significant factors. CONCLUSIONS: Stage M0 + M1 was the most powerful favorable prognostic factor. In Saudi Arabia more patients present with advanced disseminated disease, 41% M2 + M3, than in the West, and this impacts adversely on overall survival. Total resection and standard radiation treatment were not sensitive prognostic factors in a treatment environment in which 78% of patients underwent at least 90% tumor resection and 60% received standard radiation treatment. In order to improve the proportion of patients able to complete radiation treatment, consideration should be given to limiting resection when the attainment of total resection is likely to be morbid, and to delaying rather than omitting radiation treatment in the patient severely compromised postoperatively.

Prognostic Factors in Hodgkin's Disease.

Prognostic factors in Hodgkin's disease (HD) are reviewed. The Ann Arbor staging classification remains the basis for evaluation of patients with HD. However, subgroups of patients with differing prognoses exist within the individual stages. In pathological stages I and II, the number of involved regions and the tumor mass in each region are important, and an estimate of the total tumor burden has proved significant. B symptoms, histological subtype, age, and gender are also generally significant but less important. Prognostic factors for laparotomy findings in clinical stages I and II are: number of involved regions, disease confined to upper cervical nodes, B symptoms, gender, histology, age, and mediastinal disease (variable influence). In clinical stages I and II, the same prognostic factors apply as for pathological stages I and II and for laparotomy findings, and also some indirect indicators of extent of disease such as erythrocyte sedimentation rate, anemia, and serum albumin. In advanced disease the number of involved nodal and extranodal regions, the total tumor burden, B symptoms, age, gender, histology, and a number of hematologic and biochemical indicators are significant. Research into serum values of certain HD-associated antigens and cytokines may in the future provide valuable tumor markers in HD.

Prognostic factors for pleural lymphoma patients.

Prognostic factors in 47 patients with pleural lymphocytic lymphoma developing in chronic tuberculous pyothorax were evaluated using Cox's proportional hazards model. There were 41 men and six women, aged 44-80 (median 61) years. Approximately 70% of the patients had localized disease in Stages I and II, and 30% advanced disease in Stages III and IV. Histologically, 27 patients had the diffuse large, immunoblastic type and 12 had others. In the other seven patients, histological subtyping of the lymphocytic lymphoma was impossible because of degenerative or necrotic changes in the histologic specimens. A diagnosis of lymphocytic lymphoma of B-cell type was made in one case using combined cytologic and surface maker findings on a cell suspension. In addition, immunologic and immunohistochemical studies revealed another 40 cases to be proven B-cell lymphomas. Poor performance status and elevated levels of BUN and GPT were significantly associated with shortened survival in a Cox's proportional hazards model. A poor performance status and high levels of serum BUN and GPT suggested a marked deterioration in a patient's condition. When compared with previous literature describing prognostic factors in patients with B-cell lymphomas and with lymphocytic lymphomas with unfavorable histologies or associated with long-standing inflammations, the only common prognostic factors was performance status. The significance of primary site in predicting survival from lymphocytic lymphoma is discussed.

Prognostic factors in inflammatory breast cancer. Univariate and multivariate analysis.

Between 1958 and 1985, 107 patients with nonmetastatic inflammatory breast cancer (IBC) received radiotherapy as all or part of initial treatment at the Mallinckrodt Institute of Radiology. For this review, the diagnosis of IBC was made on the basis of either clinical or histopathologic criteria. Fifteen factors of potential prognostic significance were evaluated, by both univariate and multivariate analysis. For relapse-free survival, univariate analysis suggested prognostic value for initial tumor size, discrete versus diffuse tumor mass, adjuvant chemotherapy, and mastectomy. In the multivariate analysis, the independent prognostic factors, in order of significance, were mastectomy, diffuse versus discrete tumor mass, and race (marginal). For survival, univariate analysis suggested prognostic value for initial tumor size, diffuse versus discrete tumor mass, nodal stage, year of treatment, adjuvant chemotherapy, and mastectomy. In the multivariate analysis, the prognostic factors in order of significance were mastectomy and chemotherapy (marginal). The diagnostic selection group showed no prognostic value, suggesting that either clinical or histopathologic criteria justify the diagnosis of IBC. Our results appear to support a role for surgery as part of the combined modality approach to this disease.
