[The use of the pectoralis major myocutaneous flap in cervicofacial and particularly buccopharyngeal, surgery. Apropos of 42 cases].

During the last two years, we have used a pectoralis major myocutaneous flap in 42 cases (28 after radiotherapy). The immediate post-operative periods were very simple and the flap reliability was remarkable: only three partial necrosis and no total necrosis were observed. This technique seems to be an important contribution in the field of buccopharyngeal surgery, especially in the case of extensive tumors involving the tongue. In that case, initial radiotherapy followed by extensive surgery with myocutaneous flap reconstruction seems to be the best therapeutic strategy. It is the authors' feelings that local control will probably be better but long term results will be still poor. Effectively, in case of extended tumors general prognosis has to be taken in account as well as local prognosis.

In vitro interactions of TNO6 with human plasma.

The ability of TNO6 to react with human plasma was investigated by in vitro incubation of plasma or plasma fractions with injectable TNO6. HPLC, ultrafiltration and flameless atomic absorption spectrophotometry were used to separate the platinum-containing chemical species and to measure the platinum content. The initial concentration of TNO6 in plasma declines very rapidly. The kinetics of the loss of initial TNO6 is very different from that of cisplatin loss. Most of the TNO6 is bound more quickly to proteins, while a little is transformed to less reactive or nonreactive platinum species. The level of final nonreactive platinum species depends on the particular plasma concerned. In addition, the reactivity of TNO6 towards proteins is very sensitive to Cl- concentration. The usefulness of HPLC for the study of TNO6 kinetics is demonstrated.

Lymphocytes T and pharmacokinetics after a single oral dose of levamisole in healthy and cancer subjects.

Levamisole, an anthelmintic drug with immunopotentiating activity, is shown to have variable effects on cell-mediated immunity. We have studied the effect of a single oral dose (2.5 mg/kg or 5 mg/kg) on early and spontaneous E rosettes percentages in healthy and cancer patients. Pharmacokinetic study of this compound was conducted in parallel. The results indicated that single administration of levamisole (2.5 mg/kg) in healthy men can promote an increase of early E rosettes with mean peak plasma level of 0.8 micrograms. ml-1. On the other hand, there was no change in the proportion of early E rosettes in cancer patients and in the proportion of spontaneous E rosettes in healthy and cancer subjects.

[Nasopharyngeal epitheliomas: experience of the Regional Cancer Control Center in Lille (79 cases 1970-1982)].

From 1970 to 1982, 79 cases of nasopharyngeal carcinomas were treated at the Regional Cancer Center of Lille (France). At the term of the study, it appears that patients of Central Europe origin have a rather high risk of NPC (17% of cases, that ethnic population representing about 8% of all superior aerodigestive tract carcinomas). The classical differences between well and undifferentiated tumors are founded, the first presenting local spread the other general involvement.

[Metastasis of visceral tumors in intracranial tumors. Apropos of a metastasis of a lung cancer in an intracranial meningioma].

In a 52 years old man a backward epilepsy revealed a left fronto parietal tumor. The histopathological study shows that it is a meningial tumor composed around by meningocytic proliferation with a metastasis of lung cancer in the middle. This fact was proved only two months after neurosurgical intervention. Thirty three cases of cancer with metastasis in an intracranial primitive tumor have been collected in the literature. The authors study the clinical aspects and etiopathogenic hypothesis of this surprising anatomopathological fact.
