Brief Summary:
The study population will be 50 women or men diagnosed with urothelial cancer candidates to undergo cystectomy as part of their antitumor treatment. The main objective of the study is to determine the biological effect of Vitamin D on tumor tissue phenotype; for thus, all subjects enrolled in the study will take Vitamin D supplementation 4 weeks prior undergoing surgery. Urothelial tissue will be obtained from the surgical procedure and will be studied for the Vitamin D effect on cancer cell, compared with that urothelial tissue biopsy obtained in the moment of cancer diagnosis.

Condition or disease Intervention/treatment Phase
Urothelial Carcinoma Drug: Vitamin D Phase 4

Detailed Description:

The study will enroll 50 patients (older than 18 and younger than 80 years old), recently diagnosed with urothelial cancer and candidates to undergo radical cystectomy or nephroureterectomy.

At the baseline visit, a blood sample will be obtained for 25OH-VitD analysis and all subjects will receive first dose of 10.000 IU Vitamin D. Depending of basal plasmatic Vitamin D value, patients will be stratified in either 10.000 IU treatment (25OH-VitD ≥ 20 ng/ml) or either 50.000 UI treatment dose (25OH-VitD < 20 ng/ml). Treatment will consist of 4 doses taken weekly before their scheduled cystectomy. Last study follow-up visit will be 4 weeks post-surgery. Urothelial tumor tissue collected on surgery will be used to evaluate the expression of tumor differentiation and Vitamin D markers, using genomics and proteomics approaches. Blood sample will also be collect throughout the study to evaluate the pharmacokinetics of Vitamin D in plasma and the expression of Vitamin D target genes in peripheral blood leukocytes.

Primary Outcome Measures :
  1. Analysis of gene expression in urothelial tumor tissue, comparing initial tumor biopsy and cystectomy tumor tissue exposed to Vitamin D [ Time Frame: One year post-cystectomy ]
    Measurement of mRNA levels of differentiation and Vitamin D response markers (FGFR3, CDH1, CDKN1A/p21, THBD, VDR, G0S2 and GAPDH), determined by quantitative reverse transcription PCR (RT-qPCR)

  2. Analysis of protein expression in urothelial tumor tissue, comparing initial tumor biopsy and cystectomy tumor tissue exposed to Vitamin D [ Time Frame: One year post-cystectomy ]
    Measurement of expression and distribution of differentiation and Vitamin D response markers (FGFR3, CDH1, CDH2, VDR, Ki67, CDKN1A/p21, KRT5, KRT14, KRT20 and UPK), determined by immunohistochemistry (IHC)


Secondary Outcome Measures :
  1. Analysis of gene expression in peripheral blood leukocytes [ Time Frame: One to five months post-cystectomy ]
    Changes in the expression of Vitamin D target genes (CD14, CAMP, THBD and GAPDH) of peripheral leukocytes, determined by quantitative reverse transcription PCR (RT-qPCR)

  2. Levels of serum Vitamin D [ Time Frame: Ten weeks ]
    Determination of serum 25(OH)Vitamin D for pharmacokinetics study. First Vitamin D level will be obtained at screening visit and last Vitamin D level at the end of the study 4 weeks post-cystectomy
