Tongue and tonsil cancer: staging with US.

A prospective study on the value of ultrasound (US) for the staging of 70 cases of cancer of the tongue and tonsil was performed. A real-time, high-frequency transducer was used, and the examination was often coupled with endobuccal palpation. US did not visualize the tumor in nine of 42 cases of tongue cancer (seven stage T1 and two anterior stage T2 tumors); US accurately defined tumor size in 33 cases.

Axillary lymph node metastases in breast cancer: preoperative detection with US.

The importance of axillary node status in the prognosis of breast cancer led the authors to conduct a prospective study comparing the value of clinical examination with ultrasound (US) performed by a transpectoral approach. All 60 patients examined underwent axillary dissection. Sensitivity was 45.

Comparison of ultrasonographic and histological findings for multinodular lesions of the salivary glands.

Fifteen cases of multinodular lesions of the salivary glands are presented. All nodules were hypoechoic, the largest measuring over 5 mm. The various etiologies represented included: 8 non-Hodgkin's lymphomas, 5 metastases of cancer of the tongue, 1 sarcoidosis limited to the submaxillary gland, and 1 case of oncocytosis involving all four salivary glands.

[Imaging of hepatoma. Review of 50 cases].

The authors present 50 cases of hepatoma involving 32 cirrhotic and 18 healthy livers. Only 6 cases were amenable to exeresis completed by peripheral (4 cases) or intra-arterial (2 cases) chemotherapy. In addition to a semeiological study, the usefulness of various imaging techniques (ultrasound, CT, angiography) is discussed.

[Digitalized thoracic radiography in cancerology. Present contribution apropos of 200 examinations].

The authors report a double study comparing the conventional chest radiograph and digitalised images. The first study was to visualise normal mediastinal structures (the contour of the posterior mediastinum, the azygo-oesophageal recess, the bronchial sub-segments, intermediate, carina, trachea) and showed a superiority of the digitalised image. The second study was on the recognition of radiological abnormalities in lung cancer which showed no precise superiority of the digitalised image in the mediastinum (bronchial tumour, adenopathies) and a current deficiency at the pleuro-parenchymal level (pulmonary nodules, atelectasis pleural effusion).
