Background. Percutaneous endoscopic gastrostomy (PEG) tubes have largely replaced nasogastric tubes (NGTs) for nutritional support of patients with head and neck cancer undergoing curative (chemo) radiotherapy without any good scientific basis.Methods. A prospective study was conducted to compare PEG tubes and NGTs in terms of nutritional outcomes, complications, patient satisfaction, and cost.Results. There were 32 PEG and 73 NGT patients. PEG patients sustained significantly less weight loss at 6 weeks post-treatment (median 0.8 kg gain vs 3.7 kg loss, p < .001), but had a high insertion site infection rate (41%), longer median duration of use (146 vs 57 days, p < .001), and more grade 3 dysphagia in disease-free survivors at 6 months (25% vs 8%, p ¼ .07). Patient self-assessed general physical condition and overall quality of life scores were similar in both groups. Overall costs were significantly higher for PEG patients.Conclusion. PEG tube use should be selective, not routine, in this patient population.

The overall survival of patients with malignant ureteral obstruction remains poor. Prognostic factors for decreased overall survival and prolonged hospital stay have been identified. Although the technical success of decompression has improved the subsequent complication rate is still high.

Dyspnea is a common symptom in palliative care. Despite this, there is uncertainty regarding the role of oxygen to treat the symptom in patients with advanced illness. This randomized, double-blind, crossover trial examined the effect of oxygen versus air on the relief of dyspnea in patients with advanced cancer. Following the blinded administration of air and oxygen via nasal prongs, 51 patients rated dyspnea and indicated preferences for the blinded treatments. On average, patients improved symptomatically with both air and oxygen, and there were no significant differences between the treatments. The subgroup of 17 hypoxic patients overall did not demonstrate a significant difference between air and oxygen, despite having improved oxygen saturations when administered oxygen. Hypoxia was corrected in 13 of 17 patients using the treatment dose of 4 L/min of oxygen. The experience of dyspnea is a complex, multifactorial phenomenon, with oxygen tension not correlating with the subjective experience. The administration of either air or oxygen via nasal prongs on average confers improvement of the symptom.
