The Standards, Options and Recommendations on the use of erythropoietin in cancer patients are recalled. The recent literature is analysed and allows some further comments to the SOR. Medico-economic aspects, new schedules of administration, extra-hematologic virtues of erythropoietin and its impact on cancer outcomes are debated.

Neutropenia and its subsequent infectious complications represent the most common dose-limiting toxicity of cancer chemotherapy. Febrile neutropenia (FN) occurs with common chemotherapy regimens in 25 to 40 % of treatment-naive patients, and its severity depends on the dose intensity of the chemotherapy regimen, the patient's prior history and comorbidities. Neutropenia is associated with the risk of life-threatening infections as well as chemotherapy dose reductions and delays that may compromise treatment outcome. ⋯ Colony-stimulating factors (CSFs) such as granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) are now an integral part of the prevention of potentially life-threatening FN. Important uses of CSFs in oncology are prevention of FN after chemotherapy, treatment of FN, collection of CSF-mobilised peripheral stem cells and support following peripheral stem cells transplantation. This article reviews the data supporting the clearly clinical applications of CSFs in oncology.

For many types of cancers, adjuvant chemotherapy showed a moderate but significant benefit in terms of survival improvement. In sarcomas, the situation is contrasted and depends on the histological, molecular sub-types, as well as the topography of the tumor. ⋯ Sub-groups analysis indicate a significant lengthening of survival for the soft tissues sarcomas of the extremities. Neoadjuvant chemotherapy of the soft tissues sarcomas starts should be reserved to rhabdomyosarcomas and the bone sarcomas like the osteosarcomas and the Ewing's sarcomas of bones are more susceptible to chemotherapy, which is an integral part of the treatment with a preoperative chemotherapy and, following surgery of the primary tumor, an adjuvant chemotherapy adapted to the histological response to the neoadjuvant treatment.

Multicenter Study
[Multisite validation study of questionnaire assessing out-patient satisfaction with care questionnaire in ambulatory chemotherapy or radiotherapy treatment].
Patient satisfaction is now recognised as an important quality of care outcome which is particularly relevant in oncology. Adapted from the EORTC In-Patsat32, the Out-Patsat35 is a 35-item satisfaction with care questionnaire measuring cancer outpatients' perception of hospital doctors and nurses, as well as aspects of care organisation and services. This study assessed the psychometric properties of this scale. ⋯ Items and subscales of the Out-Patsat35 and of the QLQ-C30 were not significantly correlated, underlying that the two questionnaires are assessing quite distinct concepts. The subscales of the Out-Patsat35 were not related to age, gender and education, suggesting a cultural evolution in French cancer patients towards a greater homogeneity in their opinion toward care. This study supports the acceptability to patients, and the psychometric properties of the EORTC Out-Patsat35 questionnaire.

Desmopressin (DDAVP) is a well tolerated and convenient haemostatic agent that can be used in a number of clinical conditions with bleeding diathesis. It has several effects on the haemostatic system, causing endogenous release of coagulation factor VIII, von Willebrand factor and tissue-type plasminogen activator, among others. ⋯ Our data in preclinical animal models suggest a potential application of DDAVP in the perioperative management of aggressive solid tumours. Novel vasopressin analogues with improved antitumor effects are currently in development.
