Clinical Trial
Postoperative adjuvant dendritic cell-based immunotherapy in patients with relapsed glioblastoma multiforme.
To investigate the therapeutic role of adjuvant vaccination with autologous mature dendritic cells (DC) loaded with tumor lysates derived from autologous, resected glioblastoma multiforme (GBM) at time of relapse. ⋯ Adjuvant DC-based immunotherapy for patients with relapsed GBM is safe and can induce long-term survival. A trend to PFS improvement was shown in the faster vaccination schedule. The importance of age and a minimal residual disease status at the start of the vaccination is underscored.

Multicenter Study
Phase I clinical and pharmacokinetic study of plitidepsin as a 1-hour weekly intravenous infusion in patients with advanced solid tumors.
Plitidepsin, given as a 1-hour weekly i.v. infusion for 3 consecutive weeks during a 4-week treatment cycle, was investigated in patients with solid tumors to determine the maximum tolerated dose and the recommended dose (RD) using this administration schedule. ⋯ The recommended dose for plitidepsin given as a weekly 1-hour schedule was 3.2 mg/m2/week. Muscular and liver toxicity were dose limiting at 3.6 mg/m2/week. Additional evaluation of this dose dense schedule is warranted.

Vitamin D and dihydrotestosterone pathways interact to promote the growth of prostatic tissue. The nuclear vitamin D receptor (VDR) moderates the actions of vitamin D. 5alpha-Reductase type II (SRD5A2) codes for the enzyme that converts testosterone to dihydrotestosterone in the prostate. This study tested the interactions of VDR (CDX2, FokI) and SRD5A2 (V89L, A49T) polymorphisms, and their associations with prostate cancer. ⋯ Our results indicate that the SRD5A2 V89L VV genotype interacts with VDR FokI TT/CT genotypes in NHW men and VDR CDX2 GG genotypes in HW men to increase the risk for prostate cancer.

Prostate cancer risk is increased for men carrying a pathogenic germline mutation in BRCA2, and perhaps BRCA1. Our primary aim was to test for loss of heterozygosity (LOH) at the locus of the mutation in prostate cancers from men who a carry pathogenic germline mutation in BRCA1 or BRCA2, and to assess clinical and pathologic features of these tumors. ⋯ These observations are consistent with the idea that BRCA2, but not BRCA1, is a tumor suppressor of prostate cancer.

To evaluate the potential utility of histone deacetylase inhibitors (HDACi) for treatment of retinoblastoma (RB). ⋯ HDACi should be considered for clinical trials in children with RB.
