OBJECTIVE
Treatment of head and neck tumors by the ARCON regimen has yielded high local control rates. As a result of this treatment intensification there was some increase in mainly acute toxicity of radiotherapy, but nicotinamide by itself has specific side effects such as nausea and vomiting. Due

BACKGROUND
Nicotinamide and carbogen have been shown to enhance the radiation effect in tumour models.
OBJECTIVE
Prospective evaluation of the toxicity and efficacy of carbogen and nicotinamide with external beam radiotherapy in the management of inoperable glioblastoma.
METHODS
From April 1995 to

OBJECTIVE
Nicotinamide was administered daily as a liquid formulation to head and neck cancer patients receiving a 5- to 7-week course of radiotherapy. The pharmacokinetics, compliance, and tolerance of this drug formulation were studied.
METHODS
Blood samples were drawn and nicotinamide levels

OBJECTIVE
Phase II studies in laryngeal and bladder carcinoma of accelerated radiotherapy with carbogen and nicotinamide (RT+CON) suggested a therapeutic advantage. Therefore, a randomized phase-III trial of RT+CON in locally advanced bladder carcinoma compared to radiotherapy (RT) alone was
ARCON: accelerated radiotherapy with carbogen and nicotinamide in non small cell lung cancer: a phase I/II study by the EORTC.

BACKGROUND
Non small cell lung cancers (NSCLC) are rapidly proliferating tumours, which are characterized by the presence of extensive hypoxic components, especially in patients with advanced loco-regional disease. Previous studies suggest a deleterious impact of acute (perfusion-limited) hypoxia on

Combining accelerated radiotherapy with carbogen and nicotinamide (NAM) has been proposed as a strategy to overcome the sparing effect of tumour clonogen repopulation and hypoxia. Six patients with squamous cell carcinomas of the head and neck were given accelerated radiotherapy, carbogen breathing

BACKGROUND
The EORTC has initiated studies to combine nicotinamide with carbogen in accelerated fractionation schedules (ARCON), since for some tumour types, acute and chronic hypoxia as well as treatment protraction may prejudice the outcome of radiotherapy. The tolerable dose of nicotinamide and

OBJECTIVE
Nicotinamide (NA) is currently undergoing clinical trials as a tumour radiosensitizer. The dose that can be administered is currently 80 mg/kg per day, but this may be restricted to 60 mg/kg per day by the high incidence of nausea and vomiting. To investigate some of NA's underlying

BACKGROUND
Hyperphosphatemia is a common problem in patients with end-stage renal disease (ESRD) who are on maintenance hemodialysis (HD) and contributes to the development of secondary hyperparathyroidism and cardiovascular complications. Nicotinamide (NAM) has been shown in some studies to inhibit

OBJECTIVE
ARCON (Accelerated Radiotherapy, CarbOgen, Nicotinamide) achieves a large therapeutic gain in rodents. A phase I/II study was therefore undertaken to determine its feasibility in patients with locally advanced head and neck cancer.
METHODS

BACKGROUND
Friedreich's ataxia is a progressive degenerative disorder caused by deficiency of the frataxin protein. Expanded GAA repeats within intron 1 of the frataxin (FXN) gene lead to its heterochromatinisation and transcriptional silencing. Preclinical studies have shown that the histone
