Early post transplant (F-18) 2-fluoro-2-deoxyglucose positron emission tomography does not predict outcome for patients undergoing auto-SCT in non-Hodgkin and Hodgkin lymphoma.

Positron emission tomography (PET) in conjunction with computed tomography is a frequently used modality for staging patients with lymphoma. Utility of PET-computed tomography before or early following auto-SCT has not been as rigorously evaluated. We retrospectively analyzed patients who received auto-SCT for treatment of relapsed or refractory non-Hodgkins lymphoma or Hodgkins disease between the years of 1996 and 2007. Patients who had either a PET scan following salvage chemotherapy within 14 weeks of transplantation (pre-PET), and/or a PET scan 6-14 weeks following transplantation (post-PET) were included. A total of 90 patients were identified for analysis. The median follow-up time is 3.3 years, with a range of 0.13-12.0 years. The median PFS was 4.6 years, and median OS was 5.1 years. At the time of this analysis, 34 patients (37%) experienced disease relapse, and 25 (27%) of the patients died from disease progression. In multivariate Cox proportional hazards analysis, post-PET did not predict for outcome, pre-PET positivity predicted for decrease in PFS. In conclusion, post-PET scan did not predict for PFS or OS in multivariate analysis. Positive pre-PET scan did predict for PFS as seen in previous studies, and may help identify patients who would benefit from innovative post transplant therapies.

The basis of informed consent for BMT patients.

During recent decades the doctrine of informed consent has become a standard part of medical care as an expression of patients' rights to self-determination. In situations when only one treatment alternative exists for a potential cure, the extent of a patient's self-determination is constrained. Our hypothesis is that for patients considering a life-saving procedure such as bone marrow transplant (BMT), informed consent has little meaning as a basis for their right to self-determination. A longitudinal study of BMT patients was undertaken with four self-administered questionnaires. Questions centered around expectations, knowledge, anxiety and factors contributing to their decision to undergo treatment. Although the informed consent process made patients more knowledgeable about the treatment, their decision to consent was largely based on positive outcome expectations and on trust in the physician. Informed consent relieved their anxieties and increased their hopes for survival. Our conclusion was that the greatest value of the informed consent process lay in meeting the patients' emotional rather than cognitive needs. When their survival is at stake and BMT represents their only option, the patient's vulnerability puts a moral responsibility on the physician to respect the principle of beneficence while not sacrificing the patient's right to self-determination.
