Significant antitumor T-cell responses are generated in vitro when human lymphocytes are stimulated with autologous tumor cells in the presence of bystander cells transfected with CD40L and GM-CSF. Our goal was to test this bystander-based vaccine strategy in vivo in cancer patients with stage IV disease. ⋯ Vaccination of cancer patients with autologous tumor cells and GM.CD40L bystander cells (engineered to express GM-CSF and CD40L) is safe, can recruit and activate dendritic cells, and can elicit tumor-specific T-cell responses. Phase-II trials are underway to evaluate the impact of bystander-based vaccines on melanoma and mantle cell lymphoma.

Retrospective evaluation of the prognosis scores of Tokuhashi and Tomita for life expectancy in 37 consecutive patients with spinal metastases secondary to renal cancer who underwent surgery. The score of Tokuhashi, composed of six parameters, each rated from zero to two, has been proposed in 1990 for the prognostic assessment of patients with spinal metastases. In 2001, Tomita et al. created another prognostic score, composed of three parameters, growth behaviour of the primary tumor (slow, moderate and rapid) and the evidence of visceral and bony metastases. ⋯ For surgical decisions in renal cancer patients with spinal metastases, the prognostic score of Tokuhashi appears to be much more valuable than the Tomita score.

Bilateral prophylactic mastectomy in women with increased breast cancer risk dramatically reduces breast cancer occurrence but little is known about psychosocial outcomes. ⋯ The majority of women reported satisfaction with bilateral prophylactic mastectomy and experienced psychosocial outcomes similar to women with similarly elevated breast cancer risk who did not undergo prophylactic mastectomy. Bilateral prophylactic mastectomy appears to neither positively nor negatively impact long-term psychosocial outcomes.
