A subset of survivors has cognitive impairment after cancer treatment. This is generally subtle, but may be sustained. ⋯ The main developments since the first Cognitive Workshop in 2003 have been the following. (i) studies evaluating cognitive function in patients receiving chemotherapy for cancers other than breast cancer, and in patients receiving hormonal therapy for cancer. (ii) The publication of longitudinal prospective studies which have shown that some patients already exhibit cognitive impairment on neuropsychological testing before receiving chemotherapy, and some patients have deterioration in cognitive functioning from pre- to postchemotherapy. (iii) Studies of the underlying mechanisms of cognitive impairment both in patients and in animal models. (iv) Use of structural and functional imaging techniques to study changes in brain morphology and activation patterns associated with chemotherapy. (v) At present cognitive research in cancer is limited by methodological challenges and the lack of standardization in neuropsychological studies. The current workshop addressed many of these issues and established an international task force to provide guidelines for future research and information on how best to manage these symptoms.

Randomized Controlled Trial
Dose-escalated CHOEP for the treatment of young patients with aggressive non-Hodgkin's lymphoma: II. Results of the randomized high-CHOEP trial of the German High-Grade Non-Hodgkin's Lymphoma Study Group (DSHNHL).
The addition of etoposide to combination chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone [etoposide to combination chemotherapy with cyclophosphamide, vincristine and prednisone (CHOEP)] improved outcome of young patients with good-prognosis aggressive lymphoma. To improve results further, the maximal dose-escalated version of CHOEP-21 tolerable without stem-cell support (high CHOEP: cyclophosphamide 1400 mg/m2, doxorubicin 65 mg/m2, vincristine 2 mg, etoposide 175 mg/m2 x3, prednisone 100 mg x5) was compared with CHOEP-21. ⋯ Dose-escalated CHOEP-21 does not provide clinical benefit for young patients with good-prognosis aggressive lymphomas. Since differences between chemotherapy regimens are compressed by the addition of rituximab, the results of this trial have bearing on strategies aiming to improve outcome of good-prognosis aggressive lymphomas in the rituximab era.
