文摘

Successful lung cancer management has been hindered by the limited efficacy of dietary and pharmacologic interventions to prevent or reverse cancer-associated weight loss. The addition of total parenteral nutrition to chemotherapy in early trials was associated with survival detriment. Dietary counseling and enteral supplement use are common strategies that, when evaluated in randomized trials, do not improve anthropometrics or clinical outcome in lung cancer. Pharmacologic agents including corticosteroids, cyproheptadine, growth hormone, hydrazine sulfate, dronabinol, and pentoxyphylline also have failed to improve even anthropometric parameters in this condition. Megestrol acetate use is associated with appetite stimulation and non-fluid weight gain but, when evaluated in small cell lung cancer patients receiving defined chemotherapy, failed to improve global quality of life, and survival and was associated with toxicity. New strategies for nutrition-based interventions in lung cancer cachexia must consider their potential influence on tumor growth as well as on nutritional status. Recent lung cancer prognostic analyses have identified gender differences in outcome and weight loss that suggest potential targets for combined hormonal and nutrition interventions. Emerging information regarding the influence of specific fatty acids on tumor growth and cachexia development have identified additional approaches for future evaluation.
