Introduction: Since the introduction of targeted therapies, specific lymphoma mortality has decreased. Possible long-term toxicities, however, are not known yet. This article describes the implementation of the SIMONAL study that investigates the hypothesis of an overconsumption of care after lymphoma treatment with a 10-year follow-up., Methods: After the mandatory regulatory steps (CCTIRS and CNIL) the vital status and address of 5247 patients treated in 131 French centers were retrieved using a secure web portal, in order to send a quality of life after lymphoma questionnaire. After an additional vital status validation request at the center for epidemiologic research and population health (CESP), the questionnaires were sent. Double data entry was performed on the collected data and a request to access data from France's public health insurance scheme information system (SNIIRAM) was formulated., Results: Retrieval of the addresses via the portal has been slow and multiple reminders were needed. The CESP identified 9.4 % additional deaths not known by the treatment centers. Of the 3391 questionnaires sent, the response rate was 50%. A comparison between the responders and non-responders revealed no demographic differences but showed that the responders were more often treated with targeted drugs as they were included in more recent trials., Discussion: Logistic and information technology (IT) aspects rendered the implementation of the SIMONAL study more complex, time consuming and costly. However, using the collected data, many future research questions will be addressed., (Copyright © 2017 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.)

In prostate cancer, whatever the stage of the disease, the selection of a treatment strategy is based on prognostic factors. Clinical stage, serum PSA concentration and Gleason score are among the most recognised factors. A combination of these three parameters leads to a score used to define prognostic groups that are routinely used in daily practice. More recently, predictive statistical models have been developed that were associated with nomograms. The objective of nomograms is, for a given patient, to calculate his probability to develop disease extension or relapse based on clinical, biological, histological and therapeutic (radiotherapy, hormonotherapy) data. Such nomograms are not all validated and their application in daily practice is more difficult than that of classical prognostic classifications. Nowadays, the progress and accessibility to novel technologies applied to biology will make possible in the near future the assessment of new prognostic profiles based on genetic and/or proteomic tumour characteristics.

Purpose: Some adrenal incidentalomas produce cortisol in mild excess ('subclinical' Cushing's adenomas) and can potentially induce osteopenia. Their diagnosis is usually based on exclusive tumour uptake on adrenal scintigraphy using 131I-6 beta-methyl-iodo-19-norcholesterol and on inadequate cortisol response to dexamethasone (DXM) suppression tests. The aims of the present study were to evaluate bone mineral density (BMD) and metabolic markers of bone turnover in patients with incidentalomas and to test the effect of mild hypercortisolism on bone parameters., Methods: Thirty-five patients (13 men, 22 postmenopausal women, 49-76 years) with unilateral incidentaloma were studied. BMD was measured by dual X-ray absorptiometry. Two biochemical markers of bone formation, serum osteocalcin (BGP) and bone alkaline phosphatase (bALP), and two markers of bone resorption, urinary free deoxypyridinoline (D-Pyr) and urinary carboxy-telopeptide of bone type 1 collagen (CTX), were measured by radioimmunoassay. D-Pyr and CTX were corrected for creatinine excretion., Results: Median values of lumbar and femoral T-score were -1.125 and -0.920, respectively, whereas corresponding Z-score values where normal (0.105 and 0.120, respectively). Thirty-nine percent of patients had low serum BGP values and 3% had low bALP values; 16% showed elevated D-Pyr/creatinine values and 23% increased CTX/creatinine values. Patients both with suppression of the contralateral adrenal on scintigraphy and with an inadequate cortisol response to 1 mg DXM (> 50 nmol/L) (n = 14) presented a lower femoral T-score (P < 0.02) and, to a lesser extent, a lower femoral Z-score (P = 0.11) than other patients (n = 21). The proportion of increased values of CTX/creatinine (42% versus 11%, P = 0.08) also tended to be higher in the first than in the second group of patients. These two groups of patients were similar in terms of age, but tumour size was larger (P < 0.04) and plasma ACTH value was lower (P < 0.02) in patients with scintigraphic and endocrine abnormalities., Conclusion: Subclinical hypercortisolism defined on the basis of scintigraphic and hormonal criteria seems to contribute to bone loss in patients with adrenal incidentaloma. As other possible side effects of mild hypercortisolism, these findings have to be taken into account in the therapeutic management of these patients.

The role of radiotherapy in limited stage Hodgkin's disease (HD) has been gradually changing in the past few decades, resulting in the almost complete disappearance of exclusive irradiation treatment. In reality, exclusive radiotherapy yielded satisfactory results in terms of long-term survival, but in 1999 it was becoming impossible not to take into account the late mortality rates observed in all large cohorts of HD patients. This increased mortality rate has been shown to be related to 1) cardiac toxicity of irradiation, and 2) secondary radiation-induced solid tumors. Thus, the search for efficient but less toxic new strategies can no longer be avoided. For clinically staged, limited HD, precisely defined according to specific prognostic factors, the association of chemotherapy and radiotherapy appears more and more as a standard, and with this therapeutic burden comes parallel efforts for its alleviation. The Previous Radiotherapy experience has shown that, after a chemotherapy-induced complete remission, irradiation of only the initially involved areas was enough. Ongoing trials are now exploring the possibility of a dose de-escalation, from the conventional 36 Gy to 20 Gy (as for children HD), and to maybe 0 Gy (no radiotherapy at all). In parallel, deescalation in the number of chemotherapy cycles is also being investigated. For unfavorable cases, the problem is slightly different, as a higher percentage of cases still appears to be refractory to treatment in this subgroup. Thus, while chemo-radiotherapy has clearly became the standard strategy, efforts are essentially being devoted to identify new--and hopefully more efficient--chemotherapy schemes. In Europe, most of these pending questions will be addressed in the recently initiated trials of the EORTC/GELA and of the GHSG (German Hodgkin Study Group), with the aim of offering to patients treatment which could be at least as efficient as the present schedules, and less toxic in the long term.

Patients cured of Hodgkin's disease are at high risk for developing late treatment-related complications. Radiation therapy is responsible for non malignant complications such as pulmonary, digestive, thyroid and cardiac toxicity. Chemotherapy is mainly responsible for pulmonary toxicity and gonadal dysfunction in females and in males, whatever the age at treatment. Hodgkin's disease therapy may also result in secondary malignancy which is considered the most serious complication. White the use of non leukaemogenic chemotherapy can limit the incidence of secondary leukaemia, that of secondary solid tumours is still increasing, being 15% after 20 years. Altogether, malignant and non malignant complications are still responsible for a non negligible overmortality.

The aim of the study was to assess the incident number of female breast and genital tract cancers for the whole of France. The study focused on the 1983-1987 period and on 9.1% of the French population. The incident number of female breast and genital tract cancers was estimated for each site and for each of eight French administrative regions covered by a cancer registry qualified through the National Committee of Registries (Calvados, Côte-d'Or, Doubs, Hérault, Isère, Bas-Rhin, Somme, Tarn). Information on mortality rates was available at a regional level as well as at a nationwide level. The method estimated the national incidence rate modelizing the regional age-specific incidence rate as a function of corresponding mortality rate. Breast cancer was the leading site with 25,277 new cases per year while female genital tract cancers affected about 13,856 women. The cancer risk, estimated in using cumulative rate 0-74 years, was assessed at 7.1% for breast and at 1.2%, 1.4% and 1.1% for cervix uteri, corpus uteri and ovary respectively. Breast and genital tract cancers constituted 49% of the whole of cancers in women. Observed breast incidence rate was stable through French regions. There were pronounced contrasts in cervix uteri cancer risk, and some french regions displayed a high risk close to the observed European maxima. Interregional contrasts in risk of the other genital tract cancers were less striking. This study emphasized the importance of female breast and genital tract cancers for public health in France. The main aim of the French Cancer Registries Network is to provide a comprehensive description of cancer risk in France and to produce pertinent projection to 2005 horizon, combining the present data and the already accumulated 1988-1992 data.

The possibility to perform flow cytometry was examined in a series of 167 patients with primary untreated head and neck carcinoma referred to our Institution from February 1989 to January 1992. In all cases, flow cytometry was carried out on frozen tumour samples. The Cox model was used including age, tumour size, nodal status on clinical assessment, topography, treatment, malignancy grade, S phase fraction and ploidy as independent variables and overall survival as dependent variable. In this study, ploidy could be assessed in only 73% of cases and S phase fraction and G2M in 65% of the population studied. No correlation could be evidenced between ploidy or SPF with other clinical, pathologic characteristics or clinical outcome. We conclude that flow cytometry should remain a research tool until the method has proved to be relevant in clinical routine, and until the yield of the technique can be improved.

In the absence of systematic immunohistochemistry investigations, only 25 cases (out of 69) clearly diagnosed as neurosarcoma due to the association with Von Recklinghausen disease (ie, neurofibromatosis type 1) and treated at the Institut Gustave Roussy were included in the present study. Neurosarcoma consists of a neurocristopathy whose cells migrate to several parts of the body in order to constitute neuroglia, Schwann cells, pigmented and endocrinal tissues. From 1967 to 1990, 25 cases of such neurosarcomas associated with a neurofibromatosis type 1 were seen at our institute. Three different histological terms exist for this tumour: malignant schwannoma, neurosarcoma, and more recently, malignant peripheral nerve sheath tumours (MPNST). The median age (23 years) of the patients with neurofibromatosis type 1 is lower than that of patient with isolated neurosarcoma. Their sex ratio is 2/1. Primary tumour surgical exeresis was performed in all cases, with poor results in 7. Post-operative radiation therapy was not systematically used in this series. It was administered only in cases with incomplete surgical exeresis or when a local recurrence occurred. Adjuvant CYVADIC (doxorubicin, procarbazine, cyclophosphamide, vincristine) chemotherapy was administered in 5 cases, of in cases of relapse (8). All cases but 2 (the most recent ones) relapsed within 1 to 226 months (median 7 months). In addition, 13 patients developed metastases. Overall, the 2-year and 4-year survival rates were 41% and 18%, respectively. Our observations confirm the very poor prognosis for the association of neurofibromatosis type 1 and neurosarcoma. This finding should lead to systematically associate radical surgical exeresis, post-operative irradiation and adjuvant chemotherapy in the treatment of these patients.

Studies of the effectiveness of hematopoietic cell growth factors for improving recovery from chemotherapy-induced neutropenia use the duration of neutropenia as the main end-point. To determine the effect of time of analysis and transportation on the reliability of blood counts, 40 blood samples from patients with neutropenia (neutrophils between 0.5 and 1.0 x 10(9)/L) were studied immediately after sampling then after 8, 24 and 48 hours (time factor). Some of the specimens were taken from patients hospitalized in an institution located at some distance from the laboratory and were used to evaluate the effect of specimen transportation on results. Of the three methods tested (blood smear, coulter-counter, and Malassez counting chamber), the blood smear proved the most reliable. Neutrophil counts did not change over time, although morphologic changes with a potential for causing problems in neutrophil recognition were seen. No definite conclusions can be drawn from the transportation study although variations were seen in transported versus non transported specimens. These data show that blood specimens can be analyzed without changing normal working hours. However, no more than 8 hours should be allowed to elapse between sampling and processing.

Sixty-seven patients with non-Hodgkin's lymphoma of the digestive tract with locally advanced disease (stage II) were analyzed to determine the main factors influencing survival. There were 19 patients with stage II E1 and 48 with stage II E2 disease (Musshoff classification). According to the Kiel classification, 46 percent were low grade, 46 percent were high grade, and 8 percent were unclassified. The principal sites involved included the stomach: 11 cases, small intestine: 21 cases, colon: 12 cases, and mesentery: 11 cases. Lymphoma was unique in 45 cases (67 percent). Treatment consisted of laparotomy in 61 of 67 cases: partial resection was achieved in 21 cases, complete resection in 27 cases, and exploration only in 13 cases. Chemotherapy, according to histopathological subtypes, was employed in 90 percent of cases. Radiation therapy was applied in 25 patients (37 percent), essentially when there was residual disease after surgery (17 patients). Therapeutic indications were dependent on histological subtype, extension, and the therapy regimen in use at the time of treatment. Five patients were treated by surgery only, 2 by surgery and radiation therapy, 37 by surgery followed by chemotherapy, and 23 by all three treatment modalities. Overall survival was 62 percent at 5 years. Univariate analysis showed that 5-year survival rates were not influenced by sex, age, histopathological subtype (low grade: 69 percent; high grade: 59 percent; NS) or local extension (stage II E1: 76 percent vs stage II E2: 59 percent; NS). In contrast, complete surgical excision (p = 0.06) and radiation therapy in case of local residual disease (p = 0.02) seemed to improve survival. The main prognostic factor was the achievement of a complete therapeutic response (CR) (p = 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS)

In a single-blind multicenter trial, 444 patients with duodenal ulcer (DU) proven by endoscopy were randomly assigned to treatment with either ranitidine, 150 mg, or cimetidine, 400 mg, morning and evening. Clinical assessments were carried out at 2 and 4 weeks and endoscopy at 4 weeks. The patients in the 2 groups were comparable. Cumulative healing rates at 4 weeks were 78.3 p. 100 in the ranitidine group (n = 226) and 65.6 p. 100 in the cimetidine group (n = 218) (p less than 0.003). Pain at the start was of similar severity in both groups, and disappeared at the same rate under ranitidine or cimetidine: 64 p. 100 patients were painless at 1 week, 80 p. 100 at 2 weeks and 88 p. 100 at 4 weeks. Thirty-eight patients complained of mild side effects: 22 on ranitidine (2 trial withdrawals) and 16 on cimetidine (1 trial withdrawal). Multifactorial analysis (logistic model) revealed that linear ulcers had a lower healing probability than round ulcers (p less than 0.002) whatever the treatment group (cimetidine: 47 p. 100 vs 68 p. 100, ranitidine 57 p. 100 vs 80 p. 100 respectively). Smoking habits (p less than 0.057) and age less than 40 years (p = 0.056) did not significantly influence healing rates, although smokers and younger patients under cimetidine had the lowest healing rate. Thus, at the dosage used in our trial, ranitidine is more efficient for healing DU at 4 weeks than cimetidine but not for pain relief.(ABSTRACT TRUNCATED AT 250 WORDS)

Prevalence of diabetes was estimated on the basis of both interviewing the subjects and measuring fasting blood glucose among a one per cent random sample from the population of the Gouvernorat of Tunis. Sampling was done using the household as unit and three stages of randomization. The number of households investigated was 1 449, a total of 9 712 subjects. In this sample, including 45% of males, mean age is equal to 24.8 years in males and 26.0 in females. Globally, prevalence is equal to 2.3%, half-composed of previously known diabetics. In more than 50% of them, the disease was revealed by cardinal symptoms and 17% are insulin-treated. The frequency of the disease, already known or newly diagnosed, is steadily lower than 1% in the first classes of age and then distinctly increases from thirty years of age in males and forty in females, reaching a value close to 10% after sixty years.

Local recurrences (LR) after curative surgery have been analyzed in series of 173 rectal adenocarcinomas treated between 1973 and 1983. LR predictive factors were analyzed by univariate and multivariate (Cox model) studies. Five factors had no predictive value on LR: age, sex, tumor differentiation, tumor size, and number of metastatic nodes. Five factors had a predictive value on LR: severe clinical symptoms (fixation, obstruction and perforation) (p = 0.03), tumors localized within five cm of the anal verge (p less than 0.001), intramural infiltration (p = 0.09), localization of positive nodes (p = 0.02), and tumor emboli inside the vessels (p less than 0.01). The multivariate study underlined the two main predictive factors: the tumor site within 5 cm of the anal verge (p less than 0.001) and involvement of the serosa (p = 0.05). An equation of LR risk is presented and four subgroups of different LR risk patients are defined. This study might provide guidelines for indications and evaluation of major adjuvant treatments in the highest LR risk patients.

The purpose of this study was to investigate the efficacy and safety of labetalol, an alpha and beta-adrenergic receptor blocking agent in 32 patients aged from 72 to 97 years (mean = 85 years) with blood pressure (B.P.) greater than or equal to 160/95 mmHg. This study was carried out in a double-blind, randomized, placebo-controlled design. After 6 weeks of treatment with labetalol (mean dose = 235 +/- 47.5 mg/day), the systolic pressure was lowered from 187 +/- 24 to 145 +/- 28 mmHg (p less than 0.001) and the diastolic pressure from 98 +/- 10 to 82 +/- 9 mmHg (p less than 0.001). Likewise, in the placebo group, both systolic and diastolic pressures were significantly reduced but the changes were significantly greater in the labetalol group, -33 +/- 26 versus -13 +/- 20 mmHg and -14 +/- 10 versus -8 +/- 14 mmHg respectively. Labetalol achieved B.P. control (160/95 mmHg) in 64% of the treated patients, compared to 40% in the placebo group. Two patients on labetalol discontinued their treatment due to side-effects (one bradycardia and one cutaneous reaction) compared with one patient on placebo (cardiac failure). Two other cases in the labetalol group had side-effects (one fatigue and one dizziness) which prevented increasing the treatment as necessary.

In the course of a study designed to estimate the prevalence of diabetes in the Gouvernorat of Tunis, 1449 households chosen at random were examined at home between October 1976 and June 1977. The following parameters : weight, height, tricipital and subscapular skinfold thickness were determined for each subject 3 years old or more. From the data observed on 1 889 males and 1 940 females aged from 3 to 20 years, estimates by age and sex are proposed as references for growth among the tunisian population in urban area. Then an approach of the secular trend is derived from the distributions of height according to the year of birth in the adult population.

The purpose of this study was to investigate the effectiveness and safety of enalapril in elderly people. A double-blind, randomized, placebo-controlled trial was carried out in 32 subjects aged from 75 to 97 years (mean: 86 years) with blood pressure values equal or superior to 160/90 mmHg. After 8 weeks of treatment with enalapril in doses of 20 to 40 mg/day, the systolic pressure was lowered from 190 +/- 16 to 151 +/- 19 mmHg (P less than 0.0001) and the diastolic pressure from 102 +/- 7 to 85 +/- 11 mmHg (P less than 0.0001). Systolic and diastolic pressures were also significantly reduced in subjects under placebo (from 183 +/- 16 to 165 +/- 21 mmHg, P less than 0.001; and from 101 +/- 9 to 91 +/- 13 mmHg, P less than 0.001, respectively), but the degree of reduction was significantly superior with enalapril (systolic: 39 +/- 25 vs 18 +/- 19 mmHg, P less than 0.005; diastolic: 17 +/- 13 vs 11 +/- 12, P less than 0.001); blood pressure was inferior to 160/90 mmHg in 67% of the subjects treated, as against 35% of those under placebo. Two patients under enalapril died: one on the 27th, the other on the 47th day of treatment. No relation could be established between these deaths and the drug, and this figure of 2 is not significantly different for the number of deaths expected over the same period in a population of that age-group. Among the patients under placebo, one had pulmonary embolism on the 34th day and another had a sudden increase in blood pressure on the 6th day, requiring discontinuation of treatment. It is concluded that enalapril administered alone is effective and well tolerated. Long-term studies are needed to find out whether this angiotensin-converting enzyme inhibitor is superior to a diuretic as initial treatment of arterial hypertension.

The effectiveness and safety of perindopril in elderly hypertensive patients has clearly been demonstrated. In a randomized, double-blind drug versus placebo study involving 34 such patients of mean age 84 years, we observed a 10 p. 100 fall in systolic arterial pressure (p less than 0.01) and a 9 p. 100 fall in diastolic arterial pressure (p less than 0.01) in the perindopril group. The corresponding figures in the placebo group were 5 p. 100 and 4 p. 100 respectively, the difference between the two groups not being significant. The drug was well tolerated, both clinically and biochemically. However, a significant (p less than 0.01) increase in blood potassium level (albeit within normal limits) was observed in the treated group. An open trial conducted in 91 patients (mean age 79.1 years) followed up for 6 years confirmed the acceptability of the drug despite a transient decrease of creatinine clearance recorded in one patient. The effectiveness of perindopril, evaluated less unquestionably in this open trial, was excellent, the hypertension being controlled at the end of treatment in 92.5 p. 100 of the patients. In a trial performed on healthy volunteers, Reid found that perindopril had a greater effect of arterial pressure in elderly subjects, probably due in part to their high blood pressure and to an earlier and more prolonged inhibition of the angiotensin-converting enzyme (NS).(ABSTRACT TRUNCATED AT 250 WORDS)

One hundred and fifty patients, treated for Hodgkin's disease (stages I-IIIA) in a cooperative trial and remaining in complete remission after 2 to 7 years, answered a questionnaire dealing with psychosocial status and quality of life. Many informations were gathered and studied by multiparametric methods. Quality of life of patients appears determined by three kinds of parameters: patients' characteristics (age, sex, family and work status); stage of the disease determining the intensity and duration of treatment; practical conditions of treatment. These last parameters may be improved by therapeutic team and all care-takers to decrease bad consequences of disease and treatment and also to increase quality of life after cure.

Radionuclide bone scanning carried out with technetium radiopharmaceutics detects almost all prostatic carcinoma osseous metastases. It is easy to recognize focal areas of increased tracer uptake or a diffuse increased uptake, and the test provides a synthetic view of the entire skeleton. Complementary bone radiographs are necessary if the diagnosis remains doubtful, if mechanical complications are searched and if there is a post-radiotherapeutic decrease of the tracer uptake. A bone scan is necessary before the radical treatment of the primary tumour, in order to rule out the possibility of bone metastases. The initial bone scan has also a pronostic value. However, in the follow-up of initially non-metastatic patients, serial bone scans should not be realized when clinical symptoms or biological abnormalities lack. Bone scintigraphy is also useful to monitor the course of bone metastases under treatment, especially when the value of new therapeutic agents is investigated.

One hundred and fifty patients treated for Hodgkin's disease (stage I to IIIA) in a cooperative trial, answered a questionnaire dealing partly with their information, after 2 to 7 years of complete remission. This information appears insufficient for the majority of patients (52%), at least as far as treatment and its complications are concerned. There are many significant relations with other parameters which suggest that a good level of information may improve quality of life of patients. These observations tend to increase information of patients with Hodgkin's disease, provided it is adapted to each patient.

In order to determine the usefulness of systematic radiological exploration after gastrectomy, 123 gastrectomies (39 total, 84 subtotal) performed over a 10-year period were reviewed. Control radiology had been carried out in 51% of the cases. Retrospectively, except for the lower percentage of total gastrectomies the two groups (with and without control radiology) were comparable. The overall incidence of fistula (9%) was similar to that found in the literature, bearing in mind that 90% of gastrectomies in this series were performed for cancer. The only two factors predictive of fistula were the presence of fever or of post-operative focal infection (P less than 0.001). It would appear that control radiology after gastrectomy is indicated only when post-operative fever is present. If this were done the number of useless examinations would be reduced and the cost-effectiveness ratio of radiology would be improved.

A review of literature shows that, at present, genetic factors are difficult to distinguish from environmental factors. A number of studies have put into light relationships between factors tranmetted genetically and an increased risk of breast cancer in some women. This might be a reflect of the transmission of a certain susceptibility. However, one of these factors alone cannot explain the increase of the risk. Most likely, as for many types of cancers, the development of breast cancer is due both to a multigenic transmission of a certain susceptibility and to the action of environmental factors. Though, epidemiological studies make possible to identify a high risk population. A regular follow-up of this population would permit early diagnosis and possibly prophylactic measures concerning the known environmental factors, and in particular hormonal factors.

The effects of labetalol on plasma lipoprotein metabolism were evaluated in a 3-month double-blind drug versus placebo study conducted on 30 consenting hypertensive patients, 15 of whom had normal plasma lipid levels and 15, minor type II hyperlipoproteinaemia; 20 patients received labetalol 400 mg/day and 10 the placebo. All patients remained in stable nutritional status throughout the study. Full clinical examination and blood sampling were carried out 30 days before, and on days 0, 30 and 90 of treatment. Whole blood was collected after 12 hours' fasting and immediately centrifuged prior to determination of plasma lipids (total cholesterol and triglycerides, by enzymatic assay), lipoprotein lipids (HDL, HDL2, HDL3, LDL, VLDL separated by ultracentrifugation in density gradient), apoproteins A1 and B (by laser immunonephelometry) and post-heparin lipoprotein lipase activity (PHLA). Significant changes in heart rate and systolic and diastolic blood pressures were noted in patients under labetalol but not in patients under placebo. Lipid and apolipoprotein levels were similar in both groups on day 0, and no significant variation in lipids, lipoprotein lipids and apolipoproteins were observed after 30 and 90 days of treatment with either labetalol or the placebo. At the end of treatment PHLA was unmodified in the group under placebo and raised in the group under labetalol (p = 0.05). The absence of changes in blood lipid values was found both in patients with normal lipidemia and in those with hyperlipidaemia. This study confirms that labetalol in doses of 400 mg/day has notable anti-hypertensive activity and, as previously reported and in contrast with other beta-blocking agents, is devoid of any adverse effect on lipid metabolism.
