Purpose The prognosis of metastatic prostate cancer significantly differs among individuals. While various clinical and biochemical prognostic factors for survival have been suggested, the progression and response to treatment of those patients may also be defined by host genetic factors. In this study, we evaluated genetic polymorphisms as prognostic predictors of metastatic prostate cancer. Patients and Methods One hundred eleven prostate cancer patients with bone metastasis at the diagnosis were enrolled in this study. Thirteen genetic polymorphisms were genotyped using polymerase chain reaction-restriction fragment length polymorphism or an automated sequencer with a genotyping software. Results Among the polymorphisms, the long allele (over 18 [CA] repeats) of insulin-like growth factor-I (IGF-I) and the long allele (over seven [TTTA] repeats) of cytochrome P450 (CYP) 19 were significantly associated with a worse cancer-specific survival (P = .016 and .025 by logrank test, respectively). The presence of the long allele of either the IGF-I or CYP19 polymorphisms was an independent risk factor for death (P = .019 or .026, respectively). Furthermore, the presence of the long allele of both the IGF-I and CYP19 polymorphisms was a stronger predictor for survival (P = .001). Conclusion The prognosis of metastatic prostate cancer patients is suggested to be influenced by intrinsic genetic factors. The IGF-I (CA) repeat and CYP19 (TTTA) repeat polymorphisms may be novel predictors in prostate cancer patients with bone metastasis at the diagnosis.

Tyrosine kinase inhibitor- (TKI-) based therapy revolutionized the overall survival and the quality of life in non-small-cell lung cancer (NSCLC) patients that have epidermal growth factor receptor (EGFR) mutations. However, EGFR is a highly polymorphic and mutation-prone gene, with over 1200 single nucleotide polymorphisms (SNPs). Since the role of EFGR polymorphism on the treatment outcome is still a matter of debate, this research analyzed the available literature data, according to the PRISMA guidelines for meta-analyses. Research includes PubMed, Scopus, ISI Web of Science, and 14 of genome-wide association studies (GWAS) electronic databases in order to provide quantitative assessment of the association between ten investigated EGFR SNPs and the survival of NSCLC patients. The pooled HR and their 95% CI for OS and PFS for different EGFR polymorphisms using a random or fixed effect model based on the calculated heterogeneity between the studies was applied. The longest and the shortest median OSs were reported for the homozygous wild genotype and a variant allele carriers for rs712829 (-216G>T), respectively. Quantitative synthesis in our study shows that out of ten investigated EGFR SNPs (rs11543848, rs11568315, rs11977388, rs2075102, rs2227983, rs2293347, rs4947492, rs712829, rs712830, and rs7809028), only four, namely, rs712829 (-216G>T), rs11568315 (CA repeat), rs2293347 (D994D), and rs4947492, have been reported to affect the outcome of TKI-based NSCLC treatment. Of these, only -216G>T and variable CA repeat polymorphisms have been confirmed by meta-analysis of available data to significantly affect OS and PFS in gefitinib- or erlotinib-treated NSCLC patients.

Abstract We have recently shown that the multiple tumor suppressor gene 1 (MTS1 ) encoding the p16INK4a and p19ARF cell-cycle inhibitors is inactivated by deletion or disruption in most human T-cell acute lymphoblastic leukemias (T-ALLs), representing the most frequent genetic event thus far described in this disease. To analyze the mechanism of these chromosomal events, we used cloning, sequencing, and/or polymerase chain reaction mapping to study 15 rearrangements occurring in the MTS1 locus. We found that these breakpoints occur in two clusters (MTS1bcrα and MTS1bcrβ ). The three rearrangements occurring in MTS1bcrα correspond to a recurrent recombination juxtaposing 5′ MTS2 exon 1 and 5′ MTS1 exon 1α sequences. Breakpoints for 10 of 12 rearrangements within MTS1bcrβ are located at a polymorphic (CA) repeat, suggesting that this sequence might play a role in the clustering. For both MTS1bcrα and MTS1bcrβ, sequence analyses and PCR mapping experiments show that the tightly clustered breakpoints are located in the vicinity of heptamers whose sequence is similar to those involved in the V(D)J recombination. Moreover, short deletions, GC-rich random nucleotide additions, and clone-specific junctional sequences are present in all cases, further suggesting that the rearrangements are due to illegitimate V(D)J recombinase activity. These data are the first demonstration that a tumor suppressor gene can be inactivated by the V(D)J recombinational mechanism. Moreover, they reinforce the view that this process, normally required for T-cell differentiation, plays a crucial role in the pathogenesis of T-ALL.

Androgen Levels

To elucidate the possible role of genetic variation in androgen receptor (AR), estrogen receptor α (ERα), and ERβ on serum androgen levels in premenopausal women, the CAG repeat polymorphism of the AR gene, the TA repeat polymorphism of the ERα gene, and the CA repeat polymorphism of the ERβ gene were studied in a population-based cohort of 270 women. Total testosterone, free testosterone, dehydroepiandrosterone sulfate, androstenedione, 17-hydroxyprogesterone, 3α-androstanediol glucuronide, 17β-estradiol, LH, FSH, and sex steroid hormone-binding globulin (SHBG) were measured in serum samples obtained in the follicular phase of the menstrual cycle. Women with relatively few CAG repeats in the AR gene, resulting in higher transcriptional activity of the receptor, displayed higher levels of serum androgens, but lower levels of LH, than women with longer CAG repeat sequences. The CA repeat of the ERβ gene also was associated with androgen and SHBG levels; women with relatively short repeat regions hence displayed higher hormone levels and lower SHBG levels than those with many CA repeats. In contrast, the TA repeat of the ERα gene was not associated with the levels of any of the hormones measured. Our results suggest that the serum levels of androgens in premenopausal women may be influenced by variants of the AR gene and the ERβ gene, respectively.
