[Precautions for intestinal cancer in the workplace. An initiative for secondary prevention in the BASF joint-stock company]. / Darmkrebs-Vorsorge im Betrieb. Eine Initiative sekundärer Prävention in der BASF Aktiengesellschaft.

BACKGROUND AND OBJECTIVE: The annual incidence of colorectal cancer in Germany is estimated at 27000 in men and 30000 in women. If the diagnosis is made early the cure rate is over 90%. Against this background the department of occupational medicine and health protection of the BASF Aktiengesellschaft initiated a study on the potential prevention of colorectal cancer among the staff at its Ludwigshafen site. SUBJECTS AND METHODS: The target group included all 13265 actively working employees aged 45 years or above. Those expressing interest were given a standardized questionnaire concerning risk factors for colorectal cancer and a test for occult fecal blood (FOBT). If the test was positive and/or a positive answer was given to the question on blood in the stool or on a positive family history, coloscopy - to be arranged via the general practitioner - was advised, in line with the recommendations of the German Society of Digestive and Metabolic diseases (Deutsche Gesellschaft für Verdauungs- und Stoffwechselerkrankungen). RESULTS: At the end of the study 3732 employees (337 women, 3395 men, mean age 52 years) had completed the questionnaire and the FOBT results were available. Coloscopy was recommended to 688 employees, 323 of whom (47%) underwent the investigation. Nine of the subjects already had manifest cancer, six of them in the early stage T1 or T2. Adenomatous polyps were found in an additional 61 and subsequently excised. Cost-benefit considerations at the company level or in the area of the health system, respectively, gave favourable ratios of 1:10 and 1:14. CONCLUSION: It requires considerable expenditure to increase the number of participants in the cancer prevention programme and obtain a consequent clarification of suspicious findings. Health care within a company is a valuable complementation in Germany of medical care provided by general practitioners or specialist, if close cooperation between practitioners in the given region is assured. Initiatives like the one presented here protect people personally affected against pain and distress and are also of economic value.

[Hepavir, the first observational study of one cohort of patients treated with alpha-2a interferon, monotherapy. Evaluation of asthenia and its social consequences]. / Hépavir, première étude observationnelle d'une cohorte de malades traités par interféron alpha-2a en monothérapie. Evaluation de l'asthénie et de ses répercussions sociales.

OBJECTIVES: The aim of this observational study in patients with chronic hepatitis C and treated with interferon alpha-2a was to assess 1) monitoring in everyday practice, 2) the acceptability of treatment and 3) the intensity of fatigue. METHODS: Three hundred and fifty four patients were enrolled by physicians in both teaching and general hospitals, or private practice. Before treatment, clinical, epidemiological, and virological data were collected as well as a self-evaluation of fatigue using a visual analogic scale. Clinical follow-up was assessed every 3 months during treatment and 6 months after the end of treatment and included an evaluation of fatigue and the number of workdays missed due to sickness. RESULTS: Two hundred and nineteen men and 135 women, mean age 45 +/- 13, were included. The epidemiological, histological and virological features of this group were similar to those patients usually treated for chronic hepatitis C. Before treatment, the mean measurement of fatigue was 41 on a scale from 0 (perfect form) to 100 (exhausted). Fatigue was unrelated to age, source of infection, biological activity, or histological score. It worsened in patients who stopped interferon after 3 or 6 months, but was stable in patients who continued treatment for 12 months. Fatigue decreased after the end of treatment and was unrelated to treatment response. The need to stop work was strongly related to the intensity of fatigue and the number of workdays missed due to sickness represented nearly two months out of three in 25% of active patients during the first quarter and in 15% of patients thereafter. 61% of patients self-injected interferon (mainly previous drug users) whereas 30% of patients used nurse care throughout treatment. CONCLUSION: This study not only provides a realistic evaluation of fatigue in patients with chronic hepatitis C, before, during and after treatment, but also highlights its social and economic consequences. It shows the need for further cost-effectiveness studies on new therapeutic strategies using combined treatments.
