Combined chemo-radiotherapy for stage IV undifferentiated nasopharyngeal carcinoma.

Undifferentiated nasopharyngeal carcinoma is a chemosensitive lesion, but its role in the management of local advanced disease is under investigation. Twenty-seven untreated stage IV undifferentiated nasopharyngeal carcinoma patients were treated with radiotherapy (median dose, 66.6 Gy, 1.8 Gy/day) and concomitant cisplatin (100 mg/m2 days 1, 22 and 43). After 4 weeks, patients received, every 4 weeks, 3 cycles with cisplatin (80 mg/m2 day 1) + 5-fluorouracil (1,000 mg/m2/day continuous infusion for 96 h). After radiotherapy, we observed 74% complete responses and 26% partial responses; after adjuvant chemotherapy 96% had a complete and 4% a partial response. After a median follow-up of 36 months, 81% of the patients were alive (70% with no evidence of disease). Four-year overall and disease-free survival was 70% and 60%, respectively. Concomitant chemotherapy plus radiotherapy was well tolerated, whereas adjuvant chemotherapy was more toxic. Long-term results were significantly better than those observed with radiotherapy alone.

Concomitant chemoradiotherapy followed by adjuvant chemotherapy in parotid gland undifferentiated carcinoma.

AIMS AND BACKGROUND: Undifferentiated carcinoma of the parotid gland is a poor-prognosis lesion. Results in unresectable lesions, treated with radiotherapy alone, are very disappointing. METHODS: Six patients with T3-4 N0-1 inoperable lesions were treated with conventional radiotherapy (64-70 Gy, 2 Gy per fraction 5 times a week) and concomitant cisplatin (100 mg/m2, days 1, 22 and 43). Four weeks after radiotherapy, adjuvant chemotherapy (cisplatin, 80 mg/m2, day 1, + VP16, 100 mg/m2, days 1, 3 and 5, q = 3 weeks, for 3 cycles) was given. RESULTS: A median dose of 66 Gy (range, 64-70 Gy) was delivered, and all patients received 3 courses of cisplatin during radiotherapy. Five of 6 patients received all three chemotherapeutic adjuvant courses. Two months after the end of treatment, 3 CR (50%), 2 PR (33%) and 1 NC (16%) was observed. Median CR and PR duration was 26+ and 10 months, respectively. Median overall survival was 18 months. No severe acute or late toxicity was observed. CONCLUSIONS: Concomitant chemoradiotherapy followed by adjuvant chemotherapy in advanced unresectable undifferentiated parotid carcinoma is feasibile and well tolerated. The high percentage of long-lasting CR is encouraging.

Head and neck metastases of renal cancer after nephrectomy: a report of 2 cases.

Two cases of metachronous metastases of renal cell adenocarcinoma are reported. One case presented a solitary metastasis of the ethmoid-orbit which was resected. The patient has remained well for the following 12 months. The second case presented with a secondary to the tongue and multiple metastases elsewhere. Electrodissection achieved a good palliative result.

Paclitaxel and carboplatin for recurrent salivary gland malignancies.

BACKGROUND: The use of chemotherapy for recurrent salivary gland carcinomas is under investigation. PATIENTS AND METHODS: Fourteen patients (10 males, 4 females; median age 55 years, range 20-70) with recurrent carcinomas of major (9 patients) and minor (5 patients) salivary gland origin (histology: 1 adenocarcinoma, 10 adenoid cystic carcinoma, 2 undifferentiated carcinoma, 1 mucoepidermoid carcinoma) were treated with carboplatin AUC 5.5 + paclitaxel 175 mg/m2 (3-hour infusion) on day 1 (interval = 3 weeks). All patients had been previously treated with surgery + radiotherapy and 8 with a cisplatin combination. One patient had a local lesion, 7 locoregional recurrence and metastases and 6 patients had metastases only. RESULTS: Overall 65 courses were given (median 5; range 2-6). Responses were: PR in 2 patients (14%) lasting 5 and 12 months; 7 NC (50%) with a median duration of 8.5 months (5-12); and 5 PD (36%). The median survival time was 13.5 months for PR/NC patients, 6 months for non responders; median overall survival was 12.5 months (3-17+). CONCLUSION: This combination had a moderate activity; the treatment was well tolerated and toxicity was manageable.

HIV/HCV co-infection: natural history.

HIV and HCV share common transmission pathways, but HCV is more efficiently transmitted through blood than with sexual exposure. Thus HCV coinfection is frequent in HIV seropositives, mainly in those with history of injection drug use and/or transfusion. HIV coinfection increases HCV replication rate, the rate of HCV vertical transmission and accelerates the course of hepatitis C towards cirrhosis and hepatocellular carcinoma. The evidence of an effect of HCV on HIV disease progression is less convincing. The results of several studies suggest that HCV coinfection does not hasten the progression of HIV infection towards AIDS. However two recent studies showed that HCV coinfection is independently associated with a lower restoration of CD4 counts during combination antiretroviral treatment. However this finding should be confirmed by additional studies.

[Earthenware and lead poisoning. Description of a case].

A case of acute lead poisoning caused by drinking wine that had been kept in a decorative amphora is reported. Chomico-physical analysis of the internal surface of the recipient evidenced a layer of lead paint very soluble in wine. It is hoped that this report will draw the attention of the practising physician and Preventive Medicine Departments to this unusual cause of saturnism. The craft production of earthenware recipients that have been inadequately glazed and their improper use as containers of drings of foods could be commoner than might be thought on the basis of the sporadic reporting of such cases of lead poisoning.
