Case Study: Rosai-Dorfman Disease and Its Multifaceted Aspects.

Rosai-Dorfman Disease (RDD) is a rare non-Langerhans histiocytosis, usually self-limited and presenting with massive, painless, bilateral cervical lymphadenopathy, with or without constitutional symptoms. Extranodal disease is frequently present, and may happen in the absence of lymph node involvement, symptomatology and differential diagnosis will depend on the site affected and fatal cases may occur. The authors present two cases of Rosai-Dorfman disease (RDD), diagnosed through immunohistochemistry, with different progressions, one with complete remission and one culminating in death, highlighting the variety of presentations and the diagnostic difficulty.

Health-Related Quality of Life Outcomes in Head and Neck Cancer: Results From a Prospective, Real-World Data Study With Brazilian Patients Treated With Intensity Modulated Radiation Therapy, Conformal and Conventional Radiation Techniques.

Purpose: To compare global health-related quality of life (HRQoL) and overall survival (OS) in patients with head and neck cancer treated with intensity modulated radiation therapy (IMRT), conformal radiation therapy (3DCRT) or conventional radiation therapy (2DRT).

Methods And Materials: In this real-world, multi-institutional and prospective study, HRQoL outcomes were assessed using the European Organisation for Research and Treatment of Cancer Quality-of-life Questionnaire Core 30 (EORTC QLQ-C30) and European Organisation for Research and Treatment of Cancer Quality-of-life Questionnaire Head and Neck 43 (H&N43) questionnaires. Item response theory was used to generate a global HRQoL score, based on the 71 questions from both forms.

Accelerated radiotherapy and concomitant high dose chemotherapy in non resectable stage IV locally advanced HNSCC: results of a GORTEC randomized trial.

Background: The objective was to evaluate the efficacy of a strong increase of the dose-intensity of concomitant radio-chemotherapy (RT-CT) in patients with far advanced non metastatic HNSCC.

Methods: Eligible patients had N3 disease (UICC 1997) and the primary tumor and/or the node(s) had to be strictly unresectable. Patients with palpable N2B-C were also eligible if massive nodal involvement was present.

Organ preservation protocols in developing countries.

Purpose Of Review: Conservative surgical procedures, radiotherapy and chemoradiotherapy can all be considered in organ preservation strategies for patients with head and neck squamous cell carcinoma. In spite of the contribution of well designed clinical trials, in clinical practice, especially in developing countries, results are related to variables that were usually not considered in such trials.

Recent Findings: The results of most organ preservation studies are focused on survival and larynx preservation, but an evaluation of quality of life and function of the organ is still lacking.

Preoperative sequential chemotherapy in locally advanced squamous cell carcinoma of the head and neck.

Background: Induction chemotherapy may contribute to decreased local and distant recurrences in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) resectable for cure.

Methods: Patients with previously untreated locally advanced stage III-IV (N0-2, M0) SCCHN received a dose-dense sequential regimen combining cisplatin/5-fluorouracil followed by bleomycin/methotrexate/hydroxyurea. Induction chemotherapy was followed by locoregional surgery and/or radiation therapy.

Locoregional effects of pegylated liposomal doxorubicin (Caelyx) in irradiated area: a phase I-II study in patients with recurrent squamous cell carcinoma of the head and neck.

Aim of this study was to determine the antitumour activity and toxicity of pegylated liposomal doxorubicin (Caelyx) in pretreated patients with locally recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). Caelyx was administrated as 1 h infusion every 3 weeks at doses of 35 mg/m2 (group A) and then subsequently given at 45 mg/m2 (group B). 26 patients received a total of 87 cycles.

Postoperative irradiation with or without concomitant chemotherapy for locally advanced head and neck cancer.

Background: We compared concomitant cisplatin and irradiation with radiotherapy alone as adjuvant treatment for stage III or IV head and neck cancer.

Methods: After undergoing surgery with curative intent, 167 patients were randomly assigned to receive radiotherapy alone (66 Gy over a period of 6 1/2 weeks) and 167 to receive the same radiotherapy regimen combined with 100 mg of cisplatin per square meter of body-surface area on days 1, 22, and 43 of the radiotherapy regimen.

Results: After a median follow-up of 60 months, the rate of progression-free survival was significantly higher in the combined-therapy group than in the group given radiotherapy alone (P=0.

Adjusting for patient selection suggests the addition of docetaxel to 5-fluorouracil-cisplatin induction therapy may offer survival benefit in squamous cell cancer of the head and neck.

When induction chemotherapy is used in locally advanced squamous cell cancer of the head and neck (SCCHN), patients often receive cisplatin-5-fluorouracil (PF) followed by radical loco-regional therapy. Phase II studies of docetaxel-cisplatin-5-fluorouracil (TPF) induction therapy, with or without leucovorin (L), have achieved high survival rates versus those reported in phase III PF trials. However, the distribution of prognostic factors may vary between phase II and phase III study populations, making the extrapolation of phase II TPF/L results to phase III PF populations difficult.

Head and neck cancer patients with pulmonary nodules: value and role of CT-guided transthoracic needle aspiration biopsies.

Background: To evaluate transthoracic needle aspiration biopsies of pulmonary lesions in patients with squamous cell cancer of head and neck.

Methods: Retrospective series of 85 patients with squamous cell cancer of head and neck cancer and pulmonary nodules who underwent CT-guided needle aspiration biopsy.

Results: Diagnostic samples were obtained in 85% of patients.

A comparative study of the efficacy and safety of fluconazole oral suspension and amphotericin B oral suspension in cancer patients with mucositis.

This randomized study compared the efficacy and safety of fluconazole suspension with that of amphotericin B suspension in patients with head and neck cancer who were suffering from candidiasis during cancer treatment with radiotherapy and/or chemotherapy. A total of 123 evaluable patients received 50 mg fluconazole once daily and 120 evaluable patients received 0.5 g amphotericin B thrice daily for 7-14 days depending on clinical response.
