Metastatic spinal cord compression (mscc) is an oncologic emergency that, unless diagnosed early and treated appropriately, can lead to permanent neurologic impairment. After an analysis of relevant studies evaluating the effectiveness of various treatment modalities, the Comité de l'évolution des pratiques en oncologie (cepo) made recommendations on mscc management. ⋯ Considering the evidence available to date, cepo recommends that cancer patients with mscc be treated by a specialized multidisciplinary team.dexamethasone 16 mg daily be administered to symptomatic patients as soon as mscc is diagnosed or suspected.high-loading-dose corticosteroids be avoided.histopathologic diagnosis and scores from scales evaluating prognosis and spinal instability be considered before treatment.corticosteroids and chemotherapy with radiotherapy be offered to patients with spinal cord compression caused by myeloma, lymphoma, or germ cell tumour without sign of spinal instability or compression by bone fragment.short-course radiotherapy be administered to patients with spinal cord compression and short life expectancy.long-course radiotherapy be administered to patients with inoperable spinal cord compression and good life expectancy.decompressive surgery followed by long-course radiotherapy be offered to appropriate symptomatic mscc patients (including spinal instability, displacement of vertebral fragment); andpatients considered for surgery have a life expectancy of at least 3-6 months.

Intermittent androgen deprivation is increasingly used as an alternative to continuous life-long androgen deprivation therapy for men with advanced or recurrent prostate cancer. ⋯ Level i evidence supports the oncologic equivalence of intermittent compared with continuous androgen blockade in men with biochemical failure.Compared with continuous androgen deprivation, intermittent therapy demonstrates improved quality of life and fewer side effects.Patient selection for intermittent therapy is important to maintain good oncologic results.Monitoring of prostate-specific androgen response and duration of off-treatment intervals allow for stratification of patients by risk of progression.

Numerous reports have demonstrated that liver transplantation for neuroendocrine tumour metastasis is feasible. However, perioperative risks and long-term recurrences remain significant concerns. When liver transplantation is combined with extensive intestinal or pancreatic resection, the risk is particularly high. ⋯ Recurrence after transplantation remains a significant concern, even with careful patient selection, but recurrences may remain indolent. If recurrences are progressive, they may still be amenable to additional medical or surgical therapy. A national or international consensus between oncologists and transplant specialists regarding the indications for liver transplantation is vital, because future progress will depend on careful patient selection and prospective study.

To review the empirical claims made in: Pereira J. Legalizing euthanasia or assisted suicide: the illusion of safeguards and controls. Curr Oncol 2011;18:e38-45. ⋯ Pereira's conclusions are not supported by the evidence he provided. His paper should not be given any credence in the public policy debate about the legal status of assisted suicide and euthanasia in Canada and around the world.
