RESUMEN

The carcinogenicity of HPV infection in the anogenital and oropharyngeal regions is broadly accepted. The aim of the study was to define risk factors for anal and oral HPV infections in high-risk patients with biopsy-proven severe cervical lesions (CIN2+). Altogether immunocompetent 473 females with CIN2+ were categorized into the study group and another 245 women into the control group. The strongest risk factor for anal HPV infection was the presence of cervical HPV infection (p < 0.001). Furthermore, ten or more lifetime sexual partners (p = 0.013), a sexual non-coital contact with the anal area (p < 0.001), and actively practicing anal-penetrative intercourse (p < 0.001) were significantly associated with anal HPV. A history of genital warts in the woman (p = 0.010) and the presence of genital warts in the male partner (p = 0.029) were found statistically significant for the risk of oral HPV infection. Our data suggest that the presence of HPV infection, especially high-risk genotypes, in one anatomical site poses the greatest risk for HPV infection in another anatomical site. The cervix is the main reservoir of infection, but the risk factors for anal and oral HPV infections are dissimilar according to different anatomical distances and more complex routes of transmission.

RESUMEN

The landscape of chromosomal aberrations in the tumor cells of the patients with B-ALL is diverse and can influence the outcome of the disease. Molecular karyotyping at the onset of the disease using chromosomal microarray (CMA) is advisable to identify additional molecular factors associated with the prognosis of the disease. Molecular karyotyping data for 36 patients with Ph-negative B-ALL who received therapy according to the ALL-2016 protocol are presented. We analyzed copy number alterations and their prognostic significance for CDKN2A/B, DMRTA, DOCK8, TP53, SMARCA2, PAX5, XPA, FOXE1, HEMGN, USP45, RUNX1, NF1, IGF2BP1, ERG, TMPRSS2, CRLF2, FGFR3, FLNB, IKZF1, RUNX2, ARID1B, CIP2A, PIK3CA, ATM, RB1, BIRC3, MYC, IKZF3, ETV6, ZNF384, PTPRJ, CCL20, PAX3, MTCH2, TCF3, IKZF2, BTG1, BTG2, RAG1, RAG2, ELK3, SH2B3, EP300, MAP2K2, EBI3, MEF2D, MEF2C, CEBPA, and TBLXR1 genes, choosing t(4;11) and t(7;14) as reference events. Of the 36 patients, only 5 (13.8%) had a normal molecular karyotype, and 31 (86.2%) were found to have various molecular karyotype abnormalities-104 deletions, 90 duplications or amplifications, 29 cases of cnLOH and 7 biallelic/homozygous deletions. We found that 11q22-23 duplication involving the BIRC3, ATM and MLL genes was the most adverse prognostic event in the study cohort.

RESUMEN

Context: Ovarian carcinoma is a malignancy with the highest mortality among gynecological cancers. Mutations in BRCA1/2 genes are believed to be a favorable prognostic factor and that, in general, the biological behavior of ovarian cancer in BRCA-positive individuals differs from others. However, some clinically relevant issues (i.e., prediction of response to chemotherapy and treatment of platinum-resistant BRCA-positive patients) remain unclear. Aims: (1) The aim of this study was to examine the prevalence of germline BRCA mutations in unselected recurrent ovarian cancer patient population, (2) analyze whether biological behavior of BRCA-positive tumors differs from others, and (3) analyze the effect of platinum reinduction in platinum-resistant BRCA-positive patients. Settings and Design: This was a single-institution retrospective analysis. Subjects and Methods: Consecutive recurrent ovarian cancer patients from years 2012 to 2020 were included; their BRCA1/2 mutational status was analyzed and correlated with progression-free survival (PFS), type of treatment, and response to treatment. Statistical Analysis Used: Statistical significance of differences between and among patients was tested for continuous variables by the Mann-Whitney U-test or the Kruskal-Wallis test; a maximum likelihood Chi-square test was used for categorical variables. Results: Two hundred and forty-three recurrent ovarian cancer patients were included. The median follow-up was 37 months. Pathogenic mutation in BRCA1 or BRCA2 gene was found in 18.1% of patients. There was no difference in PFS comparing BRCA-positive to BRCA-negative patients (median PFS: 10.2 vs. 10.1 months, P = 0.874); there was a difference in PFS comparing BRCA-negative versus BRCA-positive platinum-sensitive patients (9.4 vs. 14.3 months, P = 0.002). BRCA-positive platinum-resistant patients reinduced with platinum achieved a median PFS of 8 months (compared to those receiving nonplatinum treatment, median PFS: 4 months, P = 0.062). Conclusions: Germline BRCA mutations are not exclusive to platinum-sensitive ovarian cancer patients; even in platinum-resistant patients, mutation can be detected. We found no difference in PFS for platinum-sensitive BRCA-positive and BRCA-negative patients. Platinum reinduction may be considered for BRCA-positive platinum-resistant ovarian cancer patients to prolong PFS. Even these data describe only a small population, it supports the clinical practice of platinum-based chemotherapy use in platinum-resistant BRCA-positive patients.

RESUMEN

Anti-Müllerian hormone (AMH) is a protein produced already in human fetus. It has an essential role in the differentiation of the reproductive tract, regulation of the ovaries and testes. The determination of serum AMH levels is used in clinical practice. Today, especially in reproductive medicine in the assessment of ovarian reserve and in the prediction of the response to ovarian stimulation. However, in young cancer patients, it can also predict the risk of ovarian failure after anticancer treatment. It finds further use in pediatric endocrinology in the diagnosis of sexual differentiation disorders. In oncology, it is used as a tumor marker for monitoring patients with granulosa tumors. In the future, however, it is also promising to use the knowledge of AMH function for the treatment of gynecological as well as other solid malignancies expressing a tissue-specific receptor for AMH.
