Associations between skin rash, treatment outcome, and single nucleotide polymorphisms in head and neck cancer patients receiving the EGFR-inhibitor zalutumumab: results from the DAHANCA 19 trial.

Purpose: To study the associations between development of moderate to severe skin rash, clinical outcome, and single nucleotide polymorphisms (SNPs) in candidate genes in head and neck cancer patients from the DAHANCA 19 trial receiving the EGFR-inhibitor zalutumumab concurrently with radiation treatment.

Material And Methods: 310 patients were included from the zalutumumab-arm of the DAHANCA 19 study. Nine SNPs in the candidate genes EGFR, EGF, AREG, FCGR2A, FCGR3A, and CCND1 were successfully determined in 294 patients.

DAHANCA 10 - Effect of darbepoetin alfa and radiotherapy in the treatment of squamous cell carcinoma of the head and neck. A multicenter, open-label, randomized, phase 3 trial by the Danish head and neck cancer group.

Purpose: To evaluate if correction of low hemoglobin (Hb) levels by means of darbepoetin alfa improves the outcomes of radiotherapy in patients with squamous cell carcinoma of the head and neck (HNSCC).

Patients And Methods: Patients eligible for primary radiotherapy and who had Hb values below 14.0 g/dl were randomized to receive accelerated fractionated radiotherapy with or without darbepoetin alfa.

Oncocytic carcinoma of the salivary glands: A Danish national study.

Objectives: To present a Danish national series of oncocytic carcinoma (OC) patients, including data on treatment, recurrence and survival.

Methods: From the national Danish database of salivary gland carcinomas, all patients diagnosed with OC from 1990 to 2005 were identified and data concerning demographics, tumor site, clinical stage and treatment profiles were extracted. A follow-up was carried out.

Polymorphous low-grade adenocarcinoma: A Danish national study.

Objectives: To present a national series of polymorphous low-grade adenocarcinoma (PLGA) patients, including survival rates and an analysis of prognostic factors.

Materials And Methods: By merging three Danish nationwide registries, 73 patients diagnosed with PLGA from 1990 to 2005 were identified. Histological slides were reviewed and data concerning demographics, tumour site, clinical stage, treatment profiles and follow-up were retrieved.

Incidence of and survival after glottic squamous cell carcinoma in Denmark from 1971 to 2011-A report from the Danish Head and Neck Cancer Group.

Aim: To describe the incidence, disease-specific mortality (DSM), and overall survival (OS) of patients with glottic squamous cell carcinomas (SCC) in Denmark from 1971-2011 in a national population-based cohort of consecutive patients.

Materials And Methods: All patients diagnosed with glottic SCC stage I-IV between 1971 and 2011 in Denmark were included. Patients were identified from the Danish Head and Neck Cancer database, which has a coverage of approximately 100% of registered glottic cancer in Denmark.

Salivary duct carcinoma: a Danish national study.

Background: To present the first national series of salivary duct carcinoma patients, including survival rates and an analysis of prognostic factors.

Methods: By merging three Danish nationwide registries that encompass an entire population, 34 patients diagnosed with salivary duct carcinoma from 1990 to 2005 were identified. Histological slides were reviewed, and data concerning demographics, tumour site, clinical stage, treatment profiles and follow-up were retrieved.

Locally advanced head and neck cancer treated with accelerated radiotherapy, the hypoxic modifier nimorazole and weekly cisplatin. Results from the DAHANCA 18 phase II study.

Purpose/objective: A phase II clinical trial evaluating the feasibility and outcome of treating locally advanced head and neck squamous cell carcinoma (HNSCC) with accelerated radiotherapy, the hypoxic modifier nimorazole and weekly cisplatin.

Material And Methods: A total of 227 patients with stage III or IV HNSCC of the larynx, oropharynx, hypopharynx, or oral cavity where included between January 2007 and December 2010. The prescribed radiotherapy (RT) dose was 66-68 Gy in 2 Gy fractions, 6 F/W.

Salivary gland carcinoma in Denmark 1990-2005: outcome and prognostic factors. Results of the Danish Head and Neck Cancer Group (DAHANCA).

To describe outcome and prognostic factors in a national Danish series of patients treated for salivary gland carcinoma. From three Danish nation-wide registries and supplementary patient records, 871 patients diagnosed with primary major or minor salivary gland carcinoma in the period from 1990 to 2005 were identified. A total of 796 (91%) histological specimens were revised according to the WHO 2005 classification.

Salivary gland carcinoma in Denmark 1990-2005: a national study of incidence, site and histology. Results of the Danish Head and Neck Cancer Group (DAHANCA).

To describe the incidence, site and histology (WHO 2005) of salivary gland carcinomas in Denmark. Nine hundred and eighty-three patients diagnosed from 1990 to 2005 were identified from three nation-wide registries. The associated clinical data were retrospectively retrieved from patient medical records.

The Danish national guidelines for treatment of oral squamous cell carcinoma.

The treatment strategy for oral squamous cell carcinoma in Denmark has traditionally varied between the different head and neck oncology centres. A study group within the Danish Society for Head and Neck Oncology (DSHHO) was formed with the aim of optimising and standardising the treatment strategy. The approach was to use single modality treatment for stage I, stage II and some stage III and combined modality treatment for stage III and IV.

Salvage laryngectomy and pharyngocutaneous fistulae after primary radiotherapy for head and neck cancer: a national survey from DAHANCA.

Objective: In 1998, the Danish Society for Head and Neck Oncology decided to conduct a nationwide survey at the five head and neck oncology centers with the aim of evaluating the surgical outcome of salvage laryngectomy after radiotherapy with special emphasis on identifying factors that could contribute to the development of pharyngocutaneous fistulae.

Patients: A total of 472 consecutive patients undergoing postirradiation salvage laryngectomy in the period July 1, 1987-June 30, 1997 were recorded at the five head and neck oncology centers in Denmark. Age ranged from 36 to 84 years, median 63 years, 405 men and 67 women.
