Extravasation of some cytostatics applied i, Thrombophlebitis Onkologie. Local treatment is usually ineffective, and so far surgical excision Thrombophlebitis Onkologie ulcera is the only curative approach. Tetrachlorodecaoxygen anion complex TCDO has shown high activity in healing chronic leg ulcera, by increasing pO2 in hypoxic wound tissue and stimulating phagocytosis as one of anti-inflammatory processes To study the local activity of TCDO in tissue necrosis and chronic ulcera caused by cytostatic extravasation, 23 patients with local skin complications underwent local treatment with TCDO, made as isotonic water solution.

Seventeen patients experienced only local edema with redness, while 6 patients showed deep chronic ulcera. All the skin changes were complications after i, Thrombophlebitis Onkologie. The treatments with TCDO followed months after ulcera appeared, while skin inflammations were treated days after they occurred.

TCDO Thrombophlebitis Onkologie applied locally twice a day by impregnated cotton tissue for weeks. Evaluable were only measurable lesions. Thrombophlebitis Onkologie 17 patients with only skin inflammation 3 patients Thrombophlebitis Onkologie complete resolution, 8 partial resolution and 6 had stable lesions.

In 6 patients with deep chronic ulcera a longer treatment 6 weeks was needed, and in 5 of them the complete epithelization and resolution occurred. One patient had a partial wound healing. No side effects of treatment were observed. The effect of locally applied TCDO in chronic ulcera seems to be preferable to surgical treatment. A controlled study will show the exact therapeutic value of this new anti-inflammatory compound. National Center for Biotechnology InformationU. Didn't get the message?

N Engl J Med ; Armand Trousseau died in Therefore, he was incapable of making observations in or lecturing inThrombophlebitis Onkologie, as Thrombophlebitis Onkologie by Prandoni et al. These investigators cited an English translation of Trousseau's work without realizing that it had been published posthumously. Trousseau published his initial observations of cancer associated with venous thrombosis in 3. In he had the frightening experience of diagnosing his own syndrome in himself, when unilateral leg swelling developed 4.

He died the following year of gastric carcinoma 5. Deep-vein thrombosis and the incidence of subsequent symptomatic cancer, Thrombophlebitis Onkologie. N Engl J Med ; Cancer and clotting -- Trousseau's warning. Clinique Medicale de l'Hotel-Dieu de Paris. Pioneer clinician MD Medical Newsmagazine ; Prandoni and colleagues make statistical errors that may very well affect their conclusions. They compare the incidence of cancer among three study groups: The comparisons of the length of time until the development of cancer between the group with recurrent idiopathic thrombosis and each of the other two groups are invalid.

The comparison between the group with recurrent idiopathic thrombosis and the group with idiopathic thrombosis is flawed because the group of 35 patients with recurrent idiopathic thrombosis is a subgroup of the patients with idiopathic thrombosis. The Mantel-Haenszel log-rank method assumes that independent groups of patients are being compared.

Moreover, although follow-up for the patients with idiopathic thrombosis begins Thrombophlebitis Onkologie the initial diagnosis of thrombosis, follow-up for the patients with recurrent idiopathic thrombosis is calculated from the subsequent thrombotic episode that defines this group.

Thus, the six events occurring in the 35 patients contained in both the idiopathic-thrombosis and recurrent-idiopathic-thrombosis Varizen der Beingeschwüre do not match in time, because the time from the initial to the subsequent thrombosis has been subtracted from the follow-up of the patients in the group with recurrent idiopathic thrombosis.

This statistical comparison is therefore also wrong, because the time scale for the comparison differs for the two groups. The comparison between the group with recurrent idiopathic thrombosis and the group with secondary thrombosis is also flawed, for the same reason.

Appropriate comparison of the recurrent-idiopathic-thrombosis group with the other groups would require statistical methods designed to compare groups whose membership is determined by Thrombophlebitis Onkologie occurring Thrombophlebitis Onkologie follow-up: Nevertheless, the primary Thrombophlebitis Onkologie between patients with idiopathic thrombosis and patients with secondary thrombosis is valid and suggests that unrecognized cancer may be a cause of a subgroup of these idiopathic thromboses.

The statistical analysis of failure time data. Regarding the recommendation by Silverstein and Nachman of carcinoembryonic antigen as a screening test for cancer, we believe that there is no proof of its value and that it will lead to many unnecessary endoscopic procedures.

Only 30 to 40 percent of patients with localized colon cancer have elevated titers of carcinoembryonic antigen 1,2. Considering that these patients will almost all be taking anticoagulants, it would seem likely that tests of the stool for occult blood would be a much more useful way to screen for Thrombophlebitis Onkologie. It is unlikely that a patient with a colonic tumor would have a stool negative for blood if the test was done properly on three separate days.

Our greater concern Thrombophlebitis Onkologie the number of unnecessary and unrewarding colonoscopic procedures that a borderline elevation in carcinoembryonic antigen would lead to. Tumor markers in cancer of the colon and rectum. Dis Colon Rectum ; I challenge the Thrombophlebitis Onkologie in the editorial by Silverstein and Nachman that all patients with idiopathic deep venous thrombosis should be examined for occult neoplasms.

A malignant tumor should be suspected if thrombosis is recurrent, occurs at an odd site, or is associated with thrombophlebitis, Thrombophlebitis Onkologie, although in patients with such tumors the presence of an underlying cancer is usually obvious 1. The careful study by Prandoni et Thrombophlebitis Onkologie. A critical reading of these reports shows that patients Thrombophlebitis Onkologie recurrent or atypical-site thrombosis are included, 3,5 that venography was not always used to establish the diagnosis of deep venous thrombosis, 3,5 and that it is unclear whether any of the patients with idiopathic deep venous thrombosis had coexisting thrombophlebitis, Thrombophlebitis Onkologie, which would raise the possibility of an underlying neoplasm Finally, the editorial ignores work that contradicts the purported linkage between truly idiopathic deep venous thrombosis and the later development of cancer Although these three series were retrospective, they studied all patients given diagnoses of lower-limb deep venous thrombosis over a designated period, and follow-up data were provided on 98 to percent of the cases.

Even if a link between idiopathic deep venous thrombosis and malignant disease of later onset had been Thrombophlebitis Onkologie established, it would be a far cry from concluding that such patients would benefit Thrombophlebitis Onkologie early diagnosis of an underlying cancer 2, Thrombophlebitis Onkologie.

A solitary idiopathic lower-limb deep venous thrombosis without thrombophlebitis merits a hunt for cancer only if there are abnormalities on physical examination, blood Thrombophlebitis Onkologie, erythrocyte sedimentation rate, or chest film Trousseau's syndrome and other manifestations of chronic disseminated coagulopathy in patients with neoplasms. Idiopathic deep vein thrombosis in an apparently healthy patient as a premonitory sign of occult cancer.

Postgrad Med J ; Deep venous thrombosis and pulmonary embolism: Siegelman and Needleman for their historical footnote. Anderson and Roberson state Thrombophlebitis Onkologie statistical Thrombophlebitis Onkologie may affect the validity of the increased risk of malignant disease that we observed in patients with recurrent idiopathic deep-vein thrombosis.

As we indicated in our article, with regard to the incidence of malignant disease we compared patients with recurrent idiopathic venous thromboembolism with patients with idiopathic deep-vein thrombosis that did not recur and patients with secondary thrombosis, using logistic-regression analysis.

This type of statistical analysis is appropriate and sufficient for this purpose. In addition, we presented curves of the cumulative incidences of malignant disease to show the occurrence of such disease in relation to the time elapsed since the thrombotic episode. For the subgroup of patients with recurrent idiopathic venous thromboembolism, this curve was calculated as a function of the time elapsed since the recurrent episode i.

This latter curve is of particular interest Thrombophlebitis Onkologie the clinician, since Thrombophlebitis Onkologie in whom recurrent venous thromboembolism will later develop cannot be identified at the moment of their first event.

Siegelman and Needleman for correcting our historical revisionism, Thrombophlebitis Onkologie. We share the concern of Drs. Epstein and Kankaria that routine population screening with carcinoembryonic antigen might result in a large number of negative and expensive colonoscopic examinations. The reason for this concern is not as clear, however, in patients with idiopathic deep venous thrombosis who have a serious risk of underlying cancer, Thrombophlebitis Onkologie.

We do not agree that the studies reported by Aderka et al, Thrombophlebitis Onkologie. The two studies noted by Thrombophlebitis Onkologie. O'Connor that report incidences of less than 20 percent were both retrospective 5,6. One of these, the one by Anlyan et al, Thrombophlebitis Onkologie.

InThrombophlebitis Onkologie, when this study was published, diagnostic methods were much less sophisticated than at present and were likely to include a substantial number of false positive errors. Although it is true that the study by Aderka et al. Impedance plethysmography is reported in numerous large studies to have sensitivities and specificities of more than 95 percent, so it is unlikely that the failure to perform contrast phlebography influenced this study.

The three retrospective studies referred to by Dr, Thrombophlebitis Onkologie. O'Connor were not mentioned in our editorial because their nature did not allow conclusions to be drawn. The study by Griffin et al. The design of the study, however, did not distinguish between idiopathic and secondary deep venous thrombosis.

In addition, there were significant differences between patients and controls in such important variables as age, sex, Thrombophlebitis Onkologie, and underlying diseases.
