The impact of nutritional status on the prognoses of patients with advanced head and neck cancer

Bioelectrical Impedance Phase Angle as a Prognostic Indicator of Survival in Head-and-Neck Cancer

“…The incidence of malnutrition in cancer patients ranges between 40% and 80%, and the prevalence ranges from 50% to 80% depending on tumour type, tumour location, stage of disease, treatment received, and the nutrition assessment method used 6 . Malnutrition and nutrition deficits all have a significant effect on mortality, morbidity, and quality of life in patients with hnc [7][8][9][10] . Timely identification of problems with a patient's nutrition could improve prognosis, increase response to therapy, and reduce the rate and severity of complications.…”

“…In patients with advanced hnc who undergo surgery, lymph node stage, non-radical resection margins, and occurrence of major postoperative complications have been demonstrated to affect disease-specific survival in men and women alike. The combination of male sex, preoperative weight loss, and major postoperative complications has been associated with earlier death 8 . Nutrition status as measured by bia or sga has been tested as a prognostic factor in a few studies.…”

The scored Patient-generated Subjective Global Assessment (PG-SGA) and its association with quality of life in ambulatory patients receiving radiotherapy

“…The incidence of malnutrition in patients with cancer ranges from 40 to 80% (Ollenschlager et al, 1991;Baldwin et al, 2001) and most frequently occurs in patients with cancer of the head and neck (van Bokhorst-de van der et al, 1999). Malnutrition is of concern as it increases the risk of infections, treatment toxicity and health-care costs and decreases response to treatment, quality of life (QoL) and life expectancy (Grant et al, 1994;Ottery, 1996b;Rivadeneira et al, 1998;Nitenberg et al, 2000).…”

Defining the Indications for Prophylactic Percutaneous Endoscopic Gastrostomy Tubes in Surgically Treated Head and Neck Cancer Patients

“…Because malnutrition can result in reduced immunosurvelliance, it may contribute to early local and distant cancer recurrence. (18,19) Avoidance of treatment induced malnutrition may prevent these complications, and prophylactic placement of PEG tube provides access for the delivery of nutrition. Identification of the risk factors which contribute to prolonged enteral support ensures PEG placement in the appropriate patients.…”
