[Adverse effects of antitumor and antileukemic chemotherapy. 2].

Aplastic anemia is the most severe hematologic side-effect. All chemotherapeutic agents, with the exception of bleomycin and L-asparaginase, may induce aplasia, but the degree of hematotoxicity varies according to the drug. With the exception of acute leukemia in which drug-induced aplasia is part of the treatment, aplasia must be prevented through perfect knowledge of the posology and injection schedules for each drug, as well as by adjusting doses to the patient's hematological status. If aplasia develops, intensive hematological care is requisite. The most common cardiac side-effect is toxic cardiomyopathy caused by anthracyclines, which must be diagnosed early by EKG recordings before each injection and repeated ultrasonography or dynamic cardiac scintigraphy. The risk of toxic cardiomyopathy makes it requisite not to exceed the maximal doses set for each drug. Pulmonary side-effects include acute hypersensitivity pneumopathy and chronic diffuse interstitial fibrosis, the latter being more common and mainly caused by bleomycin. The risk of chronic fibrosis demands that patients be closely monitored and that the total dose be kept under 300 mg. Renal toxicity usually results in acute transient renal failure, as with cisplatinum, and requires a thorough biological study before each injection. Vesical hemorrhage, which is threatening in some instances, may occur with cyclophosphamide. VM26 and VP16 may induce anaphylactic shock. Allergic symptoms are possible with L-asparaginase and bleomycin.

[Complications of antitumor and antileukemic chemotherapy. 1].

The recent development of chemotherapy in the treatment of cancer and leukemia requires that all practitioners involved have a thorough knowledge of the sometimes life-threatening side-effects of chemotherapeutic agents. All these agents, whether used alone or in a combination, carry a risk because of their lack of specificity which make active on normal cells, especially those with a rapid turn-over such as the hematopoietic cells or the cells of the digestive tract. Prior to the prescription of a chemotherapeutic regimen, the acceptable risk must always be clearly defined, according to the seriousness of the disease and to the patient's age, physical condition and psychological status. During the course continuous monitoring adjusted to the specific toxicity of the agents used is requisite. More or less prominent asthenia and weight loss are common, as the result of various physiopathological mechanisms. Digestive disorders may consist only of nausea and emesis or include mucosal lesions with diarrhea as the main feature. Vincristine and vindesine are responsible for constipation. Hepatic toxicity, which is less common, is usually due to L-asparaginase. Transient hair loss is the most frequent cutaneous side-effect. Hyperpigmentation, photosensitivity, nail lesions, cellulitis and ulcerations may occur, as well as specific lesions with bleomycin. High fever during injection often occurs with this last agent.

[Management of advanced breast cancer in post-menopausal women. A comparative trial of hormonal therapy, chemotherapy, and a combination of both].

A randomized trial was done in 98 post-menopausal women with breast cancer. Hormonal receptors had not been assayed in any patient. Patients were given hormonal therapy with tamoxifen and drostanolone propionate (n = 34), or chemotherapy with the CMF protocol (n = 30), or a combination of both (n = 34). The results are in favour of hormonal therapy alone, which gave the best immediate objective responses, the least adverse side-effects, and possibly improved survival rates.

[Retroperitoneal malignant xanthogranuloma (author's transl)].

A rare retroperitoneal malignant xanthogranuloma is described. The patient developed malignant bone lesions followed by brain localization, and died three years later. At autopsy a very large cystic retroperitoneal tumor with osteolytic lesion of sacrum was found. A review of cases diagnosed as retroperitoneal xanthogranuloma indicates that this lesion seems to be a particular form of the wide group of malignant fibrous histiocytoma with xanthomatous and inflammatory cells. Moreover it could be a primary malignant fibrous histiocytoma of bone. Furthermore, difficulties of differential diagnosis of these tumors are discussed mainly with histiocytosis X.

[Mortality due to carcinoma of the stomach between 1954 and 1974. Changes in France (author's transl)].

A study of changes in mortality due to carcinoma of the stomach in France between 1954 and 1974 was undertaken on the basis of probable levels standardised on the French population in 1968. There was a marked fall in this mortality for both sexes. In the male, the initial level in 1954 was 54.8/100 000 and the decrease was of the order of 1.35 deaths per 100 000 per year, i.e. an annual fall of -3.21%. This phenomenon was more marked during the second period (1965--1974): - 3.88%, than during the first period (1954--1963: - 2.38%. In the female, with an initial mortality rate of 31.25/100 000, the annual decrease was 31.25/100 000, i.e. an annual fall of - 3.49%. This fall was - 3.09% for the first ten year period and - 4.80% for the second period. Thus in France, in common with many other countries, there has been a marked decrease in mortality due to carcinoma of the stomach, for both sexes, and this phenomenon became progressively more notable during the period of the study.

[Mortality of bladder cancer in France: 1952--1976. Trends and increase, particularly in the South of France (author's transl)].

Trends in mortality from bladder cancer have been described with several statistical methods using bi and multivariate analysis. Between 1952 and 1976, the mortality by bladder cancer was marked by an increase for both sexes with a predominance among the males (annual increase + 3,65%, against 1.34% among the females). In 1976, the age-adjusted rate/100,000 of mortality was 11,35 for males and 3,20 for the females showing an high sex-ratio. The computerized mapping of this cancer geographical distribution shows a significant predominance in the south of France and also a high statistically significant correlation with the geographical distribution of lung and gallbladder cancer mortality in France.

[Mortality of carcinoma of uterine cervix in France : 1950-1976, trends and geography (author's transl)].

A study of changes in mortality due to carcinomas of cervix uteri in France between 1950 and 1976 was undertaken. Rates increased slightly over the whole period (0.44% per year). However, from 1950 to 1968 there was an increase (1.9% per year) and from 1969 to 1976 a decrease (1.17%). This decrease may be due partly to improvements in diagnosis, screening and cure. The geographical distribution has not shown any regional particularity. There is a high significant correlation with geographical distribution of breast cancer mortality, a hitherto unknown finding in France.

[Breast cancer in man].

Mortality from carcinoma of the breast in man varied from 0.6 to 0.8 per 100,000 from 1950 to 1970. Over the same period the equivalent figures in women were 22 to 29 per 100,000. From 1955 to 1968, the Enquête Permanente Cancer recorded 537 cases of carcinoma of the breast in men. 293 of which were seen before any treatment. This last group is described with respect to the age of the patient, the topography of the tumour, the histology, the tumor node metastasis and treatment. Survival rates were as follows: 39.2% at 5 years, 23.7% at 10 years and 16% at 20 years. The relative survival was 49% at 5 years, 37.5% at 10 years and 43.8% at 20 years. These results are identical to those published for numerically similar series. In this enquiry, a comparison between the results of carcinoma of the breast in men and women showed no difference.

[Polychemotherapy of advanced breast cancer. Triple combination with doxorubicin. Analysis of 209 observation].

Two hundred and nine patients with breast cancer in an advanced stage were treated according to a chemotherapeutic regimen associating doxorubicin, vincristine and methotrexate, administered in courses of 5 days every three weeks. This analysis deals only with the short range results; they confirm those of a previous randomized study. A global objective response was obtained in 187 cases (89%) and a measurable regression of the lesions in 150 cases (71%); in these later cases 90 (43%) had a regression of more than 50 per cent. The most striking effects, often rapidly observed, involve sites which are not generally sensitive: liver (40%), pleura (24%) and bone (only 6%, but 8 times out of 10 a definite action on the pain syndrome). Side effects were, on the whole, acceptable (only one severe hematologic complication); however, the risk of myocardiac toxocity due to the accumulation of doxorubicin limits the utilization of this association. It thus needs to be relayed by other drug regimens which are included in a program of long term action, but has interesting characteristics as induction chemotherapy.

[Relations between biomedical variables: mathematical analysis or linear algebra?].

The authors, after a short reminder of one pattern's structure, stress on the possible double approach of relations uniting the variables of this pattern: use of fonctions, what is within the mathematical analysis sphere, use of linear algebra profiting by matricial calculation's development and automatiosation. They precise the respective interests on these methods, their bounds and the imperatives for utilization, according to the kind of variables, of data, and the objective for work, understanding phenomenons or helping towards decision.

[Use of models in the study of survival in oncology].

Observation of numerous survical surves connecting the survival rates with time usually expressed in yearly intervals has permited the elaboration of patterns describing survival probability in terms of time. Gross survival patterns, from which the most utilized is the exponential pattern, must be distinguished from comparative surival patterns that debouch into the recovery probleme. Their interest is to caracterize survival for a group of patients with the assistance of a limited number of values (three at most). From that, follow their practical applications: comparison between several groups that may differ either from the characteristics of the discase or from the received treatments and from the vital future forecasting, either on one group's level, or for an individual.
