With improvements in cancer survival rates, more patients with cancer are living longer and the influence of nutrition, lifestyle, physical activity as well as supportive care during and after chemotherapy is of increasing interest. In several malignancies smoking cessation increases cancer survival. Similar effects are expected by healthy nutrition. Regular physical activity of cancer patients reduces drug interactions of chemotherapy, decreases the number of comorbid conditions, and helps patients maintain independence as long as possible. For supportive care during chemotherapy the 5-HT3 receptor antagonists are more effective for the prevention of chemotherapy-induced nausea and vomiting. There are several colony-stimulating factors (e.g. GCSF, erythropoietin) for hematopoietic recovery post-chemotherapy. Altogether supportive care of chemotherapy reduces toxicity and increases efficacy.
