Review Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
[Value of the combination of oral ondansetron with methylprednisolone as soon as the first cure in mild emetogenic chemotherapy. Groupe français d'étude de l'ondansétron].
This multicentre randomized single-blind parallel group study compared the efficacy of oral ondansetron plus methylprednisolone (OND+MPS) with conventional antiemetic strategies (TH) over 4 consecutive courses in moderately emetogenic chemotherapy. This study was conducted in naive patients receiving a minimum of 3 cytotoxics including adriamycin (> or = 35 mg/m2) and cyclophosphamide (> or = 500 mg/m2) plus an other alkylating agent. Of the 364 patients included in the study, 70% had a breast cancer and 30% a lymphoma. ⋯ Ninety-two percent of patients from OND+MPS group preferred to continue their treatment versus 76% in the TH group (p < 0.001). Concerning the quality of life assessed by FLIC and FLIE questionnaires, the analysis showed a significant difference at the end of the treatment in favor of OND+MPS (p = 0.037 and 0.0075 respectively). This study showed the interest in using the combination OND+MPS right from the first course of moderately emetogenic chemotherapy.

The aim of optimizing drug therapy for an individual patient is to maximize the likelihood of a desired therapeutic effect and to minimize the likelihood of toxicity. The excellent correlations between renal function and carboplatin total body clearance and between carboplatin area under the plasma concentration by time curve and thrombocytopenia allow calculation by Chatelut formula of carboplatin dosage.

Craniospinal irradiation is the gold standard treatment used in non metastatic medulloblastoma as prophylaxis against central nervous system (CNS) metastases. However, given the severe late effects caused by this procedure in children under 3 years of age, most pediatric oncologists are currently treating these patients with conventional chemotherapy in order to postpone or even avoid irradiation. In the French Society of Pediatric Oncology (SFOP) this attitude has been adopted since 1990. ⋯ One complication-related death occurred 1 month post BMT. With a 75% response rate, this HDC proved to be very efficient in relapsed medulloblastoma. A longer follow-up is necessary to demonstrate whether, after a local relapse, HDC could replace craniospinal irradiation as prophylaxis against CNS metastases.

Randomized Controlled Trial Clinical Trial
[Preventive analgesic effect of intraoperative administration of ibuprofen-arginine on postmastectomy pain syndrome].
The efficacy of preemptive analgesia on postoperative pain is discussed. From experimental neurophysiological data, the present policy of preventive analgesia aims at precluding modifications of the nervous system secondary to a nervous lesion and the appearance of chronic pain, particularly of the neurogenic kind. The post-mastectomy pain syndrome (PMPS) falls within the realm of neurogenic pain and is still poorly understood and underestimated. ⋯ Postoperative radiotherapy and lymphoedema were statistically associated with PMPS (p = 0.019 and p = 0.011). The perioperative preventive administration of a non-steroid anti-inflammatory drug reduces neither the incidence of pain in the first post-operative months, nor the appearance of PMPS at 6 months. These results suggest that others factors than the nervous lesion may play a role in the occurrence of PMPS, as radiotherapy, lymphoedema, but also psychosocials factors.
