Soft-tissue sarcomas of adults; study of pathological prognostic variables and definition of a histopathological grading system.

The pathological features of 155 adult patients with soft-tissue sarcomas were studied retrospectively, in an attempt to set up a grading system for these tumors. As the first step, seven histological criteria (tumor differentiation, cellularity, importance of nuclear atypia, presence of malignant giant cells, mitosis count, pattern of tumor necrosis and presence of vascular emboli) were evaluated in a monofactorial analysis. Five of these (tumor differentiation, cellularity, mitosis count, tumor necrosis, and vascular emboli) were correlated with the advent of metastases and with survival. A multivariate analysis, using a Cox model, selected a minimal set of three factors (tumor differentiation, mitosis count, and tumor necrosis) the combination of which was necessary and sufficient to retain all the prognostic information. A grading system was elaborated, which turned out to be correlated with the advent of metastasis and with patients' survival. A second multivariate analysis introducing clinical prognostic features showed that the histological grade was the most important prognostic factor for soft-tissue sarcomas. Thus, this grading system appears to be highly interesting because of its prognostic value and the facility of its elaboration. However, its reproducibility should be tested.

[Male breast tumours. Anatomico-clinical study based on 73 cases (author's transl)].

Breast cancer is 100 times less frequent in males than in femalees. In this series the predominant histological form clearly was adenocarcinoma, present in 69 out of 73 patients. The patients' age varied from 7 to 82 years. In 91% of the cases, the malignancy presented as a painless, isolated tumour, often associated with retraction of the nipple. After 5 years 68% of patients operated upon immediately after diagnosis and 35% of those initially treated by radiations were still alive, as were 72% of patients with less than 7 cm tumours and 44.8% of those with larger tumours. It appears that breast cancer in males is less aggressive than is usually believed. Its histological features and its treatment are comparable to those of femal breast cancer.

Adenocarcinoma↗

[Meningeal carcinomatosis in adults (author's transl)].

Twenty cases of carcinomatous meningitis in adults, treated in the Gustave Roussy Institute between 1970 and 1980, are reviewed. In fourteen cases meningitis was secondary to breast cancer. Initial inflammation was present in 90% of the mammary tumors. Clinical features as well as biochemical and cytological findings in cerebrospinal fluid are described. The various therapeutic regimens using radiotherapy and intrathecal chemotherapy are analyzed in terms of survival and compared with other published studies. The most significant point is the necessity for early diagnosis which improves survival. However, prognosis for this metastatic disease is always very poor.

Pharmacokinetics of 2-methyl-9-hydroxyellipticinium acetate (NSC-264137) in cancer patients (phase I study).

In 12 cancer patients we studied the pharmacokinetics of a new antitumor compound, elliptinium, which is a quaternary ammonium derivative of ellipticine, after i.v. infusion. The main parameters were calculated by means of the ADAPT program based upon plasma concentrations and urinary elimination determined by a high performance liquid chromatographic assay and fluorescence detection. The mean apparent volume of distribution for the central compartment, V1, is 2.8 l, the total plasma clearance is 971 ml/min, with a renal clearance of 127 ml/min. The mean elimination half-life, t1/2, z, is 23.7 hr, but shows a large interindividual variation. Urinary elimination is quite low (16%), with the main part (12%) excreted in the first 24 hr. In vitro plasma protein binding (78%) was found to be independent of the concentration (0.1-5.0 micrograms/ml).

[N-Methyl-9 hydroxy-ellipticine (NSC 264-137) in the treatment of malignant metastases. Preliminary results (author's transl)].

In a phase II trial 2 N-Methyl-9-Hydroxy-Ellipticine (NMHE) was administered in weekly infusions of 100mg/m2 over 1 hour to patients with malignant metastases. Prior to injection, the drug was dissolved in 250 ml isotonic glucose. The results were evaluated in 67 patients. Objective regression was observed in 23 (34%) and was superior to 50% in 10 cases. Patients showing signs of regression under treatment were mostly those with breast cancer (10/24 cases), soft tissue sarcoma (3/9 cases) and renal cancer (2/8 cases). The main toxic effect was haemolysis (2 cases), probably due to an immunoallergic mechanism. Attention is drawn to the lack of bone marrow toxicity.

Antitumor activity, pharmacology, and toxicity of ellipticines, ellipticinium, and 9-hydroxy derivatives: preliminary clinical trials of 2-methyl-9-hydroxy ellipticinium (NSC 264-137).

Ellipticine and some derivatives are highly cytotoxic substances which kill L1210 cells at concentrations ranging form 10(-8) to 10(-6)M. Some compounds in this series bind with high affinity to DNA (affinity constant between 10(7) M-1 and 10(5) M-1) by intercalation between base pairs. The antitumoral properties of these derivatives are thought to be related to their DNA-binding ability. Both 9-hydroxylation of ellipticine and quaternarization of 2-pyridinic nitrogen tend to increase DNA binding and antitumor activity. 2-Methyl-9-hydroxyellipticine (NSC 264-137) was selected for a phase I and later for a phase II trial in human cancer. This drug does not affect blood cell counts in animals or in man. It is not mutagenic in the Ames' test nor teratogenic in mice, but is endowed with anti-inflammatory properties and induces a marked decrease of motoricity in mice. Transient bradycardia and decrease of blood pressure are the most noticeable cardiovascular effects in dogs. This compound administered at 80-100 mg/m2/week in 1-h intravenous (IV) infusion induces objective remissions in about 25% of patients suffering from advanced breast cancer refractory to all other treatment. These remissions, which occurred after 3-4 weeks, lasted for 1-18 months. This drug seems particularly to improve the condition of patients suffering from oesteolytic breast cancer metastasis. Activity against anaplastic thyroid carcinoma and ovarian carcinoma has also been observed in some cases. Toxic side effects are nausea and vomiting (one-third of the patients), hypertension (less than 10% of the patients), muscular cramp (one-third of the patients), fatigue which can be very pronounced (in most patients after 3 months of treatment), mouth dryness, and mycosis of the tongue and esophagus (less than 20% of the patients).

[Cis-diamminated-dichloroplatinum (CDDP) in the chemotherapy of testicular dysembryomas and choriocarcinomas (author's transl)].

Cis-diamminated-dichloroplatinum is an effective drug in the treatment of testicular dysembryomas and choriocarcinomas. It may obtain results in cases resistant to combinations of drugs already known as being effective against such tumours. It is thus worthy of integration into treatment protocols for forms of these tumours with a poor or reserved prognosis (cases with metastases or lymph node involvement or with chorial participation).

Choriocarcinoma↗

[Mammary carcinoma: prognosis value of intra-mammary spread (author's transl)].

At the conclusion of this study based on 327 cases of breast cancer T1, T2 T3 (less than 7 cm) No, N1, Mo Pev O, treated by mastectomy and axillary dissection without previous treatment, it appears that the microscopic dissemination to the nipple has a pejorative prognosis value. The 5 years is 84 p. 100 when there is no nipple dissemination, 74 p. 100 when there is an intraductal nipple dissemination, and 57 p. 100 when there is lymphatic or interstitial nipple dissemination. These differences have a statistical value. This value does not seem connected with other pathological prognosis factors: tumors size, Bloom histopronostic grading, and the number of nodes invaded. The intra-mammary spread without nipple involvment has no prognostical value.

[Current treatment of testicular cancers].

The treatment and prognosis of dysembryoma of the testis have been transformed by the dissection of retroperitoneal nodes and by combination chemotherapy as early as possible. Routine retroperitoneal node dissection followed by early and prolonged chemotherapy lead to a hope of cure in more than 75% of cases of dysembryoma of the testis. Similar early chemotherapy is effective and indicate for choriocarcinoma of the testis and retroperitoneal node dissection may be of value in tumours in which the chorial element is "minor".

[The value of cis-diamminedichloroplatinum (cis-platinum) CDDP in the treatment of stage III and IV cancers of the ovary (author's transl)].

Cis-diamminedichloroplatinum is remarkably useful in stage III and IV cancers of the ovary. It should therefore be added to the armamentarium of chemotherapeutic substances used up till now. This effectiveness adds extra indication to the use of chemotherapy as a first treatment for stage III cancers of the ovary after the lesions have been reduced as far as possible by surgery.
