[Advances in head and neck cancers on behalf of the French Intergroup ORL and GORTEC]. / Évolution des concepts dans les cancers des voies aérodigestives supérieures, sous l'égide de l'Intergroupe ORL (GORTEC, GETTEC, GERCOR).

Head and neck cancers are the fifth among the most common cancers in France. Two thirds of cases occur at an advanced stage. For advanced disease, progression-free survival, despite undeniable progress, remains below 50% at three years. The last 20 years have been marked by the necessity to identify situations where less intense surgery and/or radiotherapy and/or chemotherapy is possible without jeopardizing the prognosis, and situations where a therapeutic intensification is necessary and results in a gain in survival while better preserving function with less toxicity. French cooperative groups gathering radiation oncologists (GORTEC), surgeons (GETTEC) and medical oncologists or physicians involved in the management of systemic treatments in head and neck cancers (GERCOR) are now belonging to the INCa-labelled Intergroup ORL to deal with the challenges of head and neck cancers.

[Nocardia brasiliensis leg ulcer and nodular lymphangitis in France]. / Ulcère de jambe et lymphangite nodulaire à Nocardia brasiliensis en France métropolitaine.

INTRODUCTION: Nocardia brasiliensis is a very rarely reported cause of chronic phagedenic ulcerations. We report the case of an elderly woman who developed such an infection after falling on her right leg on the road in the Bresse country (an essentially agricultural and bovine-cattle breading region) and developed a chronic phagedenic ulcer secondarily complicated by nodular lymphangitis of the thigh. CASE REPORT: A 75 year-old woman fell on her right leg on the side of the main road outside her hamlet in the Bresse country and secondarily developed a chronique phagedenic ulceration. We first considered her as suffering from pyoderma gangrenosum. A complete scanning only revealed an autoimmune thyroiditis and a rapidly healing gastric ulceration, and none of the treatments, either local or systemic, helped the skin condition to heal. After 3 weeks of application of a local corticoid ointment, the patient developed fever, general malaise, an exacerbation of her wound and an infiltration of the skin round her knee, together with nodular lymphangitic dissemination. A supplementary bacterial swab disclosed massive proliferation of a slow-growing Gram-positive bacillus, which proved to be Nocardia brasiliensis, together with a methicillino-sensitive Staphylococcus aureus. The treatment with sulfamethoxazole-trimetoprim gave a rash after 12 hours and was changed to amoxicillin and clavulanic acid, which rapidly proved to be permanently effective. DISCUSSION: The revelation of this particular slow-growing bacteria is difficult and requires bacterial swabs. Nocardia brasiliensis is relatively rare in primary skin ulcerations and we discuss the reasons why an elderly women should find this bacteria on the road outside her hamlet in the French countryside. This particular infectious condition requires general scanning, to make sure that the primary skin condition does not extend to other organs. We review the therapeutical options for patients who exhibit allergic reactions to the classically effective antibiotic drugs.

Randomized trial of radiation therapy versus concomitant chemotherapy and radiation therapy for advanced-stage oropharynx carcinoma.

BACKGROUND: We designed a randomized clinical trial to test whether the addition of three cycles of chemotherapy during standard radiation therapy would improve disease-free survival in patients with stages III and IV (i.e., advanced oropharynx carcinoma). METHODS: A total of 226 patients have been entered in a phase III multicenter, randomized trial comparing radiotherapy alone (arm A) with radiotherapy with concomitant chemotherapy (arm B). Radiotherapy was identical in the two arms, delivering, with conventional fractionation, 70 Gy in 35 fractions. In arm B, patients received during the period of radiotherapy three cycles of a 4-day regimen containing carboplatin (70 mg/m(2) per day) and 5-fluorouracil (600 mg/m(2) per day) by continuous infusion. The two arms were equally balanced with regard to age, sex, stage, performance status, histology, and primary tumor site. RESULTS: Radiotherapy compliance was similar in the two arms with respect to total dose, treatment duration, and treatment interruption. The rate of grades 3 and 4 mucositis was statistically significantly higher in arm B (71%; 95% confidence interval [CI] = 54%-85%) than in arm A (39%; 95% CI = 29%-56%). Skin toxicity was not different between the two arms. Hematologic toxicity was higher in arm B as measured by neutrophil count and hemoglobin level. Three-year overall actuarial survival and disease-free survival rates were, respectively, 51% (95% CI = 39%-68%) versus 31% (95% CI = 18%-49%) and 42% (95% CI = 30%-57%) versus 20% (95% CI = 10%-33%) for patients treated with combined modality versus radiation therapy alone (P =.02 and.04, respectively). The locoregional control rate was improved in arm B (66%; 95% CI = 51%-78%) versus arm A (42%; 95% CI = 31%-56%). CONCLUSION: The statistically significant improvement in overall survival that was obtained supports the use of concomitant chemotherapy as an adjunct to radiotherapy in the management of carcinoma of the oropharynx.
