Background and objectiveFew studies have compared short-term androgen deprivation (STADT) combined with high-dose radiotherapy (STADT-RT) versus high-dose radiotherapy (RT) alone in localized prostate cancer.MethodsThe GETUG 14 study randomized 376 patients to RT (n = 191) or STADT-RT (n = 179). The RT dose was 80 Gy in both arms. STADT consisted of monthly triptorelin and daily flutamide for a total duration of 4 mo, starting 2 mo before RT. Disease-free survival (DFS) was the primary endpoint. Secondary endpoints were overall survival (OS), biochemical failure (BF), metastasis failure (MF), toxicity, and quality of life.Key findings and limitationsAmong the 370 patients in the modified intention-to-treat population, 241 (65%) had intermediate-risk and 107 (28%) high-risk prostate cancer. At median follow-up among surviving patients of 84 mo (interquartile range 62-99 mo), the 5-yr DFS rate was 76% in RT arm versus 84% in STADT-RT arm (hazard ratio [HR] 0.64, 95% confidence interval [CI] 0.43-0.94]). ADT addition decreased BF (HR 0.45, 95% CI 0.28-0.72) and MF (HR 0.5, 95% CI 0.23-1.11) but not OS (HR 1.22, 95% CI 0.65-2.29). There were no significant differences for RT versus STADT-RT in the incidence rates for grade ≥2 toxicity in terms of acute gastrointestinal (GI) toxicity (26%, 95% CI 20-32 vs 26%, 95% CI 20-33), acute genitourinary (GU) toxicity (39%, 95% CI 32-46% vs 42%, 95% CI 35-50%), late GI toxicity (21%, 95% CI 16-28% vs 23%, 95% CI 18-30%), or late GU toxicity (30%, 95% CI 24-38% vs 27%, 95% CI 21-34%).Conclusions and clinical implicationsSTADT is a well-tolerated and effective strategy that can enhance oncological outcomes when combined with high-dose RT, particularly for patients with intermediate- or high-risk prostate cancer.

PMID:19022849
Transcription factor activity is modulated by bound coactivator and corepressor proteins like ZBTB7A that recruits NCOR1 and NCOR2 to the androgen response elements/ARE on target genes, negatively regulating androgen receptor signaling and androgen-induced cell proliferation .
PMID:20812024
Transcription activation is also down-regulated by NR0B2. Activated, but not phosphorylated, by HIPK3 and ZIPK/DAPK3
PMID:23275542 PMID:30373764 PMID:32818467 PMID:7961644
Upon ligand binding, translocates into the nucleus, where it heterodimerizes with ARNT and induces transcription by binding to xenobiotic response elements (XRE) .
PMID:23275542 PMID:30373764 PMID:7961644
Regulates a variety of biological processes, including angiogenesis, hematopoiesis, drug and lipid metabolism, cell motility and immune modulation .
PMID:12213388
Xenobiotics can act as ligands: upon xenobiotic-binding, activates the expression of multiple phase I and II xenobiotic chemical metabolizing enzyme genes (such as the CYP1A1 gene) .

Next to xenobiotics, natural ligands derived from plants, microbiota, and endogenous metabolism are potent AHR agonists .

Tryptophan (Trp) derivatives constitute an important class of endogenous AHR ligands .
PMID:32818467 PMID:32866000
Acts as a negative regulator of anti-tumor immunity: indoles and kynurenic acid generated by Trp catabolism act as ligand and activate AHR, thereby promoting AHR-driven cancer cell motility and suppressing adaptive immunity .
PMID:32818467
Regulates the circadian clock by inhibiting the basal and circadian expression of the core circadian component PER1 .

Inhibits PER1 by repressing the CLOCK-BMAL1 heterodimer mediated transcriptional activation of PER1 .
PMID:28602820
The heterodimer ARNT:AHR binds to core DNA sequence 5'-TGCGTG-3' within the dioxin response element (DRE) of target gene promoters and activates their transcription PMID:28602820
Response to specific ligands is species-specific. Activated by naturally occurring steroids, such as pregnenolone and progesterone. Binds to a response element in the promoters of the CYP3A4 and ABCB1/MDR1 genes
