To define the dose ratio between morphine and methadone in relation to the previous morphine dose and the number of days needed to achieve the same level of analgesia in a group of patients with advanced cancer with pain who switched from morphine to oral methadone. ⋯ The results of our study confirm that methadone is a potent opioid, more potent than believed. Caution is recommended when switching from any opioid to methadone, especially in patients who are tolerant to high doses of opioids.

Multicenter Study Clinical Trial
A phase II study of docetaxel in patients with paclitaxel-resistant metastatic breast cancer.
To evaluate the efficacy and safety of docetaxel in patients with paclitaxel-resistant metastatic breast cancer (MBC). ⋯ Docetaxel is active in patients with paclitaxel-resistant breast cancer, particularly in those who failed to respond to brief infusions of paclitaxel. Response rates were comparable to or better than those seen with other therapies for patients with paclitaxel-resistant MBC. This confirms preclinical studies, which indicated only partial cross-resistance between paclitaxel and docetaxel.

To identify prognostic variables that predict for improved biochemical and local control outcome in patients with localized prostatic cancer treated with neoadjuvant androgen deprivation (NAAD) and three-dimensional conformal radiotherapy (3D-CRT). ⋯ For patients treated with NAAD and high-dose 3D-CRT, pretreatment PSA, preradiotherapy PSA nadir response, and clinical stage are important predictors of biochemical outcome. Patients with NAAD-induced PSA nadir levels greater than 0.5 ng/mL before radiotherapy are more likely to develop biochemical failure and may benefit from more aggressive therapies.

Randomized Controlled Trial Multicenter Study Clinical Trial
Double-blind, dose-finding study of four intravenous doses of dexamethasone in the prevention of cisplatin-induced acute emesis. Italian Group for Antiemetic Research.
A 5-hydroxytryptamine 3 (5-HT3) receptor antagonist plus dexamethasone is the most efficacious antiemetic prophylactic treatment for the prevention of cisplatin-induced acute emesis, but the optimal intravenous (i.v.) dose of dexamethasone is unknown. This prompted us to perform a multicenter, randomized, double-blind, dose-finding study that compared four different doses of dexamethasone. ⋯ A 20-mg single i.v. dose of dexamethasone should be considered the most efficacious prophylactic dose for the prevention of cisplatin-induced acute emesis.

Clinical Trial
Anti-G(D2) antibody treatment of minimal residual stage 4 neuroblastoma diagnosed at more than 1 year of age.
To eradicate minimal residual disease with anti-G(D2) monoclonal antibody 3F8 in stage 4 neuroblastoma (NB) diagnosed at more than 1 year of age. ⋯ Despite high-risk nature of stage 4 NB, long-term remission without autologous (A)BMT can be achieved with 3F8 treatment. Its side effects were short-lived and manageable. The potential benefits of 3F8 in consolidating remission warrant further investigations.
