I said that when things were a bit quieter I would do some rough translation. Now the French are up to eleven ASL cases I thought I had better get on with it. I do apologise, it is a very rough translation and probably medically inexact. X did not translate the tables which I think will be quite clear to all of you. !I R&S 106054 Encs ' J?^ ` " R&S 106055 000003Q TEN CASES OF LIVER ANGIOSARCOMA EXPERIENCED IN WORKERS EXPOSED TO VCM ****** PAPER PRESENTED TO THE 19TH INTERNATIONAL OCCUPATIONAL MEDICINE CONFERENCE AT DUBROVNIK ON 28 SEPTEMBER 1978 BY : DRS J BERROD - P LAZARD - C PIERRE -AM PUECH - E RAVIER - J RETY - G SMAGGHE - ****** V; 1 At the end of the Viola and Maltoni experiments the publication of the^ evidence of the carcinogenic action of VCM and particularly the induction of ASL by this chemical agent led, as one might expect, to a large number of studies, particularly experimental studies. The Works Medical Doctors found themselves, however, confronted in their factory activities by practical problems of surveillance and prevention. It seemed likely that a worker newly recruited into the factories would be exposed only to a very small risk as a result of the effective technical measure taken during the past few years. But a considerable number of workers still employed in the factory or retired had been exposed for a number of years to concentrations of VCM which in former times seemed harmless but which in the light of recent information seemed possible agents for the induction of angiosarcomas. Knowing the evolution of this disease, it can seem fruitless to interest oneself in finding means of early detection of ASL. Nevertheless, we have been able to observe the case of a patient having undergone a surgical intervention with a survival of about two years, although the diagnosis had only been taken to the stage of clinically detectable lesions. Without ignoring the many fold and well known difficulties of cancer therapy, we consider that it is not useless to try to discover as early as possible an ASL lesion and allow the different skilled specialists to give an efficient therapy. With this in mind we have applied ourselves to the detailed study of the ten cases of ASL diagnosed in France in workers exposed to VCM. It is not possible for us, of course, in the time available to look in detail at the observations which consist of the precise data on previous occupation, clinical history, the results of various practical examinations, therapies, the results of anatomo-pathological examinations, etc. We can communicate these data to anyone in the audience interested if they should wish. We have assembled in the tables the principal elements in our observations to try to display the relevant data leading up to our surmise of a diagnosis. We hope that these tables will be sufficiently legible and we will comment on them briefly. Table No 1 Table No 1 shows that the ten cases studied were all exposed for a long time at high concentrations (11 years minimum and most of the time cleaners of autoclaves or polymerisation workers) the youngest case being 38 yrs and the oldest case 62 yrs : in processes of making emulsion, suspension and mass PVC). It should be noted that case no 1 was diagnosed in 1967 and that tie was found again as a result of an epid miological study conducted in our ; factories;- :Th ^-diagnosis has-beenconfirm d histo-pathologically ini--the t n^cases* 30 Ui a at 0 01 O) Table No 2 In Table No 2 we have gathered together previous history and tried to enumerate clinical symptoms from the first appearance. We would point out in this comparison one case only (No 4) with a record of alcohol intake and consequent hepatic troubles(?), one case (No 7) with an indisputable acro-osteolysis one year before the discovery of the ASL, one case (No 9) which presented itself after biological tests 4 years previously had shown a transitory increase of alkaline phosphatase and jaundice. Finally, in Case No 5 it was the fortuitous discovery of an angiosarcomatose costal tumour which led the works doctor to ask a specialist to look systematically for an ASL. This table displays the poverty of clinical signs of the initiation of trouble, the initial symptoms often being either an acute or haemorrhagic phenomenon or a rapid loss of weight accompanied by debility. In the majority of cases at the time of diagnosis the liver appears augmented in volume (8 times out of 10) and the spleen was also clinically enlarged (7 cases out of 10). Table No 3 37 -------------------- to Table No 3 lists the complementary practical examinations, eg scintigraphy laparoscopy and arteriography. In most cases the appearance of abnormal pictures of the right lobe and the good reproducability of these examinations which are in a good state of practical evolution reinforces clinical suspicions which are already strong. ^S090i Table No 4 Table No 4 indicates to us that in a number of cases the haemorrhagic symptoms are a characteristic of the evolution of the disease (6 out of 10). Th treatment has been surgical in all the cases. In one case there was an exploratory laparotomy; in the other cases a s gmentary hepatectomy, a multi segmentary hepatectomy or right lobe. tw nty month survival in Case No 9 is to be noted. A Furthermore one must note that Case No 7 survived thirteen months aft r the removal of a hematsmisis(?) resulting from a local haemorrage near th angiosarcoma. Radiotherapy was used in association with surgical treatment in one cas only (No 8). In Case No 5 radiotherapy was done locally near the bony lesion. Table No 5 Table No 5 gives the histopathological data. One must note the spongy aspect of the lesions in five cases, sinusoidal in four cases, papillary in two cases and massive in two cases. Th non-cancerous fibrosis of .the parenchyma is weak in five cases, much mor marked in one case (No 4), The xtent of the lesion is in general very local (Nos 1,3,6, 7 and 8) it is bony (costal) in Case No 5 which is th only case in our obs rvations wh r on has had any vidence. of metastasis. ^ ' y-\ , 3 Table No 7 Table No 7 is confined to Case No 10. This case was found diagnostically at the beginning of this year. His medical dossier comprises a series of examinations which we have displayed. It is notable that the alkaline phosphatase is raised (10.4 units against a normal of 3 units) and a bilirubin of 12 mg/litre (N 10 mg) only one month after hospitalisation with normal transaminases and normal alpha-foeto protein (6.5 - N 15). The alkaline phosphatase stayed high on 3 January 1978 (one month afterwards) the transaminases were always normal and stayed so three days before surgical intervention. They only seemed high (15/ and 113 units against a normal 40) on the day of the surgical operation. Anaemia with 3.4m hematocytes appeared only on the 7th January with a normal number of thrombocytes (day of operation). At this time arteriography had already shown an irregularity on the right lobe and scintigraphy had shown three very sharp lacunae. The slides which we will now show you show the extent of the lesions in some sections from the operation. This example highlights the difficulty if not the impossibility of early diagnosis solely by biological investigations and the study of the ten cases has served to reinforce this impression. Scintigraphy, arteriography, laparoscopy, even laparotomy are certainly more precise techniques, but in the range of our diagnostic tools can only be the exceptional method of investigation and not without risk. That is why we are now turning our studies towards ultrasonography. This test, which has the merit of being well accepted by the patients, does not carry any additional risks and seems to be capable as the technique progresses to disclose abnormal pictures with good resolution in the liver parenchyma, and seems to us capable of giving valuable information to a early diagnosis and in conjunction with biological examinations limits the number of patients who must be exposed to diagnostic techniques which are more invasive and risky. 31 (/) o oo> U1 00 J Stafford JS/MJE/DS0-107 2 February 1979 Tableau I CA3 DATE DF NAISSANCE N 1 15.4.24 EXPOSITION ANNEES AU C.V.M. lcre EXPOSITION ANNEEIj DEC RE DATE DU DATE DU DE A AU DIAGNOSTIC EXPOSITION' EXPOSITION DIAGNOSTIC DECES 1946 19 67 21 19 +++ 19.2.67 19.2.67 (etude dpi ddmi o. anr.path.)
