Introducing a standardized assessment of patients' interest in and usage of CAM in routine cancer care: chances and risks from patients' and physicians' point of view.

BACKGROUND: Cancer patients often use complementary and alternative medicine (CAM), however, standardized assessment in clinical routine is missing. The aim of this study was to evaluate a screening questionnaire on CAM usage that was published in the S3 Guideline Complementary Medicine in the Treatment of Oncological Patients. METHODS: We developed a survey questionnaire to assess the practicability of the guideline questionnaire and communication on CAM between health care providers (HCPs) and patients. We collected 258 guideline questionnaires and 116 survey questionnaires from ten clinics and held twelve semi-structured interviews with HCPs. RESULTS: 85% used at least one of the listed CAM methods, 54 participants (N = 77) never disclosed usage to a physician. The most frequently used CAM methods were physical activity (76.4%) and vitamin D (46.4%). 25.2% used at least one method, that was labeled risky by the guideline. 53.4% did not know of CAM's risk of interactions and side effects. Introducing the guideline questionnaire in routine cancer care increased the rate of patients talking to an HCP regarding CAM significantly from 35.5 to 87.3%. The HCPs stated positive effects as an initiation of conversation, increased safety within CAM usage and patients feeling thankful and taken seriously. However, due to the limited amount of time available for discussions on CAM, generalized distribution to all patients was not feasible. CONCLUSION: Institutions should focus on implementing standard procedures and resources that help HCPs discuss CAM on a regular basis. HCPs should meet the patient's demands for CAM counseling and make sure they are equipped professionally.

[Systemic therapy of soft tissue sarcomas]. / Systemische Therapie von Weichgewebssarkomen.

The gold standard for the treatment of primary, resectable, high-grade soft tissue sarcomas is complete surgical removal followed by radiotherapy. In cases where preservation of function is not possible, preoperative treatment options should be considered. Systemic therapy is the treatment of choice for metastatic soft tissue sarcomas. The most active single agents include the anthracyclines doxorubicin and epirubicin, as well as ifosfamide. While combination chemotherapy yields higher response rates, this is at the cost of increased toxicity with no evidence of prolonged overall survival. Current treatment strategies focus on the development of specific treatments for well defined soft tissue sarcoma subtypes. The first and highly successful targeted therapy was seen with the introduction of imatinib in the treatment of gastrointestinal stromal tumors.
