Laryngeal metastasis from colonic adenocarcinoma.

Metastases to the larynx from distant primaries are very rare. Usually the secondary lesion comes from an hypernephroma or malignant melanoma. A case of metastatic laryngeal tumour from a colonic adenocarcinoma, occurring in a 59-year-old woman, is presented and the routes for laryngeal spread are discussed. The poor survival-rate of these patients justified only conservative surgery.

[Ultrasound staging research of progressive pathology of the base of the tongue]. / L'indagine ecografica nello studio della patologia espansiva della base linguale.

Diagnosis of tongue tumours is often retarded mainly because tumours grow prevalently in deep muscular layers. A correct exploration of the region might be difficult solely employing clinical examination. Therefore, it would be useful to confirm the suspect of a neoplastic lesion at the base of the tongue with a promptly available imaging method. These considerations led us to evaluate ultrasonography (US) as a diagnostic tool for neoplastic lesions of this region. Initially 10 normal patients were studied in order to become familiar with US anatomy of the area. In a second phase our study involved 24 patients with diagnosed carcinoma of the tongue base and 26 patients with clinical suspect of neoplasm in the region. US examination was carried out with real-time equipment provided by a 5 Mhz convex transducer. Patients were examined in supine position with the neck hyperextended. Longitudinal, oblique and transverse scan of the submental region were obtained. The study showed that US gives detailed images of the floor of the mouth and the tongue. Neoplastic infiltration of the base of the tongue is clearly recognizable as a hypoechoic area. It was possible to detect masses ranging from 1.4 to 3.8 cm. In cases of larger lesions, US was useful in evaluating deep infiltration, whereas in other cases the method allowed the diagnosis of small lesions with submucosal growth. US did not proved to be highly reliable in the diagnosis of lesions confined to superficial planes (false negative results).(ABSTRACT TRUNCATED AT 250 WORDS)

Detection of deglutition disorders after reconstructive laryngectomy. Clinical and radiological evaluations.

Subtotal reconstructive laryngectomy is an appropriate surgical procedure for intralaryngeal squamous cell carcinoma. After this surgery the functions of the larynx are greatly modified. These functions may be retained if at least one cricoaryténoid is preserved with good function. The aim of our study was to determine the recovery of swallowing in the late postoperative period and to establish the possible causes of dysphagia. 34 patients previously submitted to reconstructive laryngectomy were studied by clinical and endoscopical evaluation as well as videofluoroscopic examination. The results of our study confirm what has been reported by other authors, that is that the sphincter function greatly altered in the early postoperative period, is progressively restored, especially when both arytenoids are preserved. Videofluoroscopic examination frequently showed the asymptomatic false passage of liquid boluses.

Treatment of advanced head and neck tumors with PEV-B regimen: a pilot study.

Thirty-seven patients with advanced head and neck tumors were treated with a polychemotherapy regimen (PEV-B: platinum 30 mg/m2 i.v., epirubicin 30 mg/m2 i.v., etoposide 75 mg/m2 i.v. on days 1 and 2 every 28 days, and bleomycin 15 mg i.m. weekly up to the total dose of 300 mg). All but 7 patients were pretreated with surgery and/or radiotherapy. Thirty-six patients were evaluable for response. Partial response (PR) was observed in 19 cases (53%), no change (NC) in 13 cases (36%) and progression (P) in 4 cases (11%). The median duration of PR was 5 months. The most frequent side-effects were leukopenia (78%), vomiting (57%) and alopecia (46%). The median duration of survival was 8 months for the responders and 5 months for the non-responders.

5-fluorouracil + folinic acid with cisplatinum and bleomycin in the treatment of advanced head and neck squamous cell carcinoma.

Thirty-six patients with advanced squamous cell carcinoma of the head and neck (SCCHN) were treated with a regimen including cisplatinum (CP) 30 mg/m2 i.v., 5-fluorouracil (5-FU) 500 mg/m2 i.v. bolus, folinic acid (FA) 200 mg/m2 i.v. in a continuous one-hour infusion, and bleomycin (B) 15 mg i.m. on the first and second days and repeated every 28 days. Thirty-three patients (25 with recurrent disease and 8 untreated) are evaluable for objective response. Of these, 4 (12%) achieved CR and 15 (45%) PR. All of the untreated patients responded. The mean duration of response in the patients with recurrent or metastatic disease was 5.5 months (range 2-10+). Remission of symptoms, such as pain and dysphagia, was obtained in 58% and in 44%, respectively. Subjective remission occurred almost exclusively in objectively responsive patients. The major side effects were leukopenia (55%) and nausea/vomiting (58%). This regimen is active in the treatment of advanced SCCHN. The quality of life may be improved in responsive patients.
