Hormone replacement therapy in gynecological cancer survivors and BRCA mutation carriers: a MITO group survey.

OBJECTIVE: Early iatrogenic menopause in gynecological cancer survivors and BRCA mutation (BRCAm) carriers undergoing risk-reducing salpingo-oophorectomy (RRSO) is a major health concern. Hormone replacement therapy (HRT) is the most effective remedy, but remains underused in clinical practice. The Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) group promoted a national survey to investigate the knowledge and attitudes of healthcare professionals regarding the prescription of HRT. METHODS: The survey consisted of a self-administered, multiple-choice 45-item questionnaire, available online to all MITO members for 2 months starting from January 2022. RESULTS: A total of 61 participants completed the questionnaire (47 out of 180 MITO centers; compliance: 26.1%). Most respondents were female (73.8%), younger than 50 years (65.6%), and gynecologic oncologists (55.7%), working in public general hospitals (49.2%). An 84.4% of specialists actively discuss HRT with patients and 51.0% of patients ask the specialist for an opinion on HRT. The rate of specialists globally in favor of prescribing HRT was 22.9% for ovarian cancer, 49.1% for cervical cancer, and 8.2% for endometrial cancer patients. Most respondents (70.5%) believe HRT is safe for BRCA-mutated patients after RRSO. Nearly 70% of physicians prescribe systemic HRT, while 23.8% prefer local HRT. Most specialists recommend HRT for as long as there is a benefit and generally for up to 5 years. CONCLUSION: Real-world data suggest that many healthcare professionals still do not easily prescribe HRT for gynecological cancer survivors and BRCA mutation carriers after RRSO. Further efforts are required to implement the use of HRT in clinical practice and to support both clinicians in recommending HRT and patients in accepting it.

Vulvar Paget's Disease: A Systematic Review of the MITO Rare Cancer Group.

Vulvar Paget's disease (VPD) is a rare form of cutaneous adenocarcinoma of the vulva, which accounts for about 1-2% of all vulvar neoplasms and mainly affects post-menopausal women. The clinical presentation is usually non-specific and mimics chronic erythematous skin lesions; therefore, the diagnosis is often difficult and delayed. Although VPD is typically diagnosed at a locally advanced stage and has a high recurrence rate, the prognosis is overall favorable with a 5-year survival of nearly 90%. Due to the limited and poor-quality evidence, there is no global consensus on optimal management. Therefore, we performed a systematic review of the literature through the main electronic databases to deepen the current knowledge of this rare disease and discuss the available treatment strategies. Wide surgical excision is recommended as the standard-of-care treatment and should be tailored to the tumor position/extension and the patient's performance status. The goal is to completely remove the tumor and achieve clear margins, thus reducing the rate of local recurrences. Non-surgical treatments, such as radiotherapy, chemotherapy, and topical approaches, can be considered, especially in the case of unresectable and recurrent disease. In the absence of clear recommendations, the decision-making process should be individualized, also considering the new emerging molecular targets, such as HER2 and PD-L1, which might pave the way for future targeted therapies. The current review aims to raise awareness of this rare disease and encourage international collaboration to collect larger-scale, high-quality evidence and standardize treatment.

Artificial neural networks reveal sex differences in gene methylation, and connections between maternal risk factors and symptom severity in autism spectrum disorder.

Aim and methods: Artificial neural networks were used to unravel connections among blood gene methylation levels, sex, maternal risk factors and symptom severity evaluated using the Autism Diagnostic Observation Schedule 2 (ADOS-2) score in 58 children with autism spectrum disorder (ASD). Results: Methylation levels of MECP2, HTR1A and OXTR genes were connected to females, and those of EN2, BCL2 and RELN genes to males. High gestational weight gain, lack of folic acid supplements, advanced maternal age, preterm birth, low birthweight and living in rural context were the best predictors of a high ADOS-2 score. Conclusion: Artificial neural networks revealed links among ASD maternal risk factors, symptom severity, gene methylation levels and sex differences in methylation that warrant further investigation in ASD.

Chemo-surgical approach in vulvar leiomyosarcoma: A case report.

INTRODUCTION: Primary sarcoma of the vulva is an extremely rare entity, representing only 1%-3% of all vulvar malignant neoplasms. Among sarcomas, leiomyosarcoma (LMS) is the most prevalent histologic variant. Due to the rarity of LMS, guidelines are lacking and phase III trials have not been carried out, so clinical management is based on local clinical practice and physician experience. CASE PRESENTATION: Here, we described a case of primary LMS of the vulva and its successful management, with the adoption of neoadjuvant chemotherapy and surgery. We report a case of a 74-year-old woman with 12.5 cm vulvar LMS. The patient received three cycles of neoadjuvant chemotherapy with a partial response. Radical vulvectomy with vulvar reconstruction with V-F flap was carried out. Surgical margins were negative. Three additional cycles of adjuvant chemotherapy were delivered. RESULTS: One year after treatment, the patient was disease-free. CONCLUSION: There are no approved therapeutic protocols for this rare neoplasia. Surgery is the mainstay of treatment. However, it is not always feasible, so neoadjuvant chemotherapy was delivered for downstaging the vulvar lesion. We suppose that neoadjuvant chemotherapy has optimized the possibilities of radical surgery. Despite the anectodical nature of this case presentation, neoadjuvant chemotherapy seems a valid therapeutic option for managing patients with bulky vulvar sarcoma. Further large collaborative studies are warranted to identify the best therapeutic option for these patients.

Correlation among maternal risk factors, gene methylation and disease severity in females with autism spectrum disorder.

Aim: To detect early-life environmental factors leading to DNA methylation changes of autism spectrum disorder (ASD)-related genes in young ASD females and reveal epigenetic biomarkers of disease severity. Materials & methods: We investigated blood methylation levels of MECP2, OXTR, BDNF, RELN, BCL2, EN2 and HTR1A genes in 42 ASD females. Results: Maternal gestational weight gain correlated with BDNF methylation levels (Bonferroni-corrected p = 0.034), and lack of folic acid supplementation at periconception resulted in higher disease severity in the ASD children (Bonferroni-corrected p = 0.048). RELN methylation levels were inversely correlated with disease severity (Bonferroni corrected p = 0.042). Conclusion: The present study revealed gene-environment interactions and potential epigenetic biomarkers of disease severity in ASD females.

Early-life maternal factors can leave marks on the DNA of the developing fetus, including changes in DNA methylation that regulate gene expression levels. These marks can pose an increased risk for several diseases, such as autism spectrum disorder (ASD) and other developmental disorders. In the present study, we searched for links between early-life maternal factors and the methylation levels of ASD-related genes in blood DNA samples of young ASD diagnosed females. We found that high maternal gestational weight gain resulted in increased methylation levels of the BDNF gene, one of the most important genes for brain development. Moreover, lack of maternal folic acid supplementation and low RELN methylation levels resulted in higher disease severity in ASD females.

Radical Surgery After Neoadjuvant Chemotherapy for Locally Advanced Neuroendocrine Cancer of the Cervix.

BACKGROUND/AIM: Although still controversial, the current treatment for locally advanced neuroendocrine carcinoma of the cervix (NECC) relies on chemoradiation (CRT). The aim of this study is to evaluate the alternative role of combined chemotherapy and surgery in treating NECC. PATIENTS AND METHODS: This is a retrospective series of patients undergoing radical surgery after neoadjuvant chemotherapy (NACT) for locally advanced NECC (stages IIB-IVA). Histological examination and immunohistochemistry were performed on surgical specimens to confirm diagnosis. Systematic literature search was conducted to identify other cases treated with chemotherapy and surgery. RESULTS: Seven patients with a mean age of 49 years were identified. The mean greatest diameter at diagnosis was 59.3±24.7 mm. FIGO stage was IIB in 14.3% of patients, IIIB in 28.6%, IIIC in 42.9%, and IVA in 14.3%. The response to NACT was partial, ranging from 50% to 80%. Neuroendocrine markers were expressed in all cases. The mean progression-free survival (PFS) and overall survival (OS) were 15.0±30.6 months and 26.3±36.4 months, respectively. Eleven studies encompassing a total of 27 patients met eligibility criteria for the systematic review. CONCLUSION: Surgery after NACT for locally advanced NECC may yield similar outcomes compared to CRT. The benefit of performing surgery as a primary approach could lie in the possibility of reserving CRT for recurrences. Since randomized clinical trials are difficult to be designed, an expert consensus is required to address the non-inferiority of radical surgery over CRT.

Physical and mental health in the oldest-old: a mixed-methods study on a southern Italy sample.

BACKGROUND: The world's aging population has been constantly increasing in the last decades, causing the number oldest-old individuals to increase. AIMS: The present study aims to explore the different variables that contribute to the oldest-old wellbeing using a mixed-methods approach, including self-reports, standardized measures, and semi-structured interviews. METHODS: Thirty-nine oldest-old (90-103) from southern Italy were involved in the study, together with a control sample of younger individuals (51-71) from the same families. RESULTS: Data suggest that the oldest-old have better mental health, higher resilience, and more optimism than younger individuals. High resilience seems to be the key variable that promotes the overall wellbeing. DISCUSSION: The oldest-old tend to have better mental health, higher resilience and more optimism than younger individuals. CONCLUSIONS: Wellbeing in the oldest-old appeared to be promoted by the sense of belonging and life purpose.

Investigation of GHSR methylation levels in thymomas from patients with Myasthenia Gravis.

BACKGROUND: Hypermethylation of the growth hormone secretagogue receptor gene (GHSR) is increasingly observed in human cancers, suggesting that it could represent a pan-cancer biomarker of clinical interest. However, little is still known concerning GHSR methylation levels in thymic epithelial tumors, and particularly in thymomas from patients with Myasthenia Gravis (TAMG). MATERIAL AND METHODS: In the present study we collected DNA samples from circulating lymphocytes and surgically resected tumor tissues of 65 TAMG patients, and from the adjacent healthy thymic tissue available from 43 of them. We then investigated GHSR methylation levels in the collected tissues searching for correlation with the clinical characteristics of the samples. RESULTS: GHSR hypermethylation was observed in 18 thymoma samples (28%) compared to the healthy thymic tissues (P < 1 × 10-4), and those samples were particularly enriched in advanced disease stages than stage I (94% were in stage II or higher). GHSR was demethylated in the remaining 47 thymomas, as well as in all the investigated healthy thymic samples and in circulating lymphocytes. CONCLUSIONS: GHSR hypermethylation is not a pan-cancer marker or an early event in TAMG, but occurs in almost 1/4 of them and mainly from stage II onward. Subsequent studies are required to clarify the molecular pathways leading to GHSR hypermethylation in TAMG tissues and their relevance to disease progression.

Association of Polymorphisms in Genes Involved in One-Carbon Metabolism with MTHFR Methylation Levels.

Methylenetetrahydrofolate reductase (MTHFR) is a pivotal enzyme in the one-carbon metabolism, a metabolic pathway required for DNA synthesis and methylation reactions. MTHFR hypermethylation, resulting in reduced gene expression, can contribute to several human disorders, but little is still known about the factors that regulate MTHFR methylation levels. We performed the present study to investigate if common polymorphisms in one-carbon metabolism genes contribute to MTHFR methylation levels. MTHFR methylation was assessed in peripheral blood DNA samples from 206 healthy subjects with methylation-sensitive high-resolution melting (MS-HRM); genotyping was performed for MTHFR 677C>T (rs1801133) and 1298A>C (rs1801131), MTRR 66A>G (rs1801394), MTR 2756A>G (rs1805087), SLC19A1 (RFC1) 80G>A (rs1051266), TYMS 28-bp tandem repeats (rs34743033) and 1494 6-bp ins/del (rs34489327), DNMT3A -448A>G (rs1550117), and DNMT3B -149C>T (rs2424913) polymorphisms. We observed a statistically significant effect of the DNMT3B -149C>T polymorphism on mean MTHFR methylation levels, and particularly CT and TT carriers showed increased methylation levels than CC carriers. The present study revealed an association between a functional polymorphism of DNMT3B and MTHFR methylation levels that could be of relevance in those disorders, such as inborn defects, metabolic disorders and cancer, that have been linked to impaired DNA methylation.

Increase in DNA methylation in patients with amyotrophic lateral sclerosis carriers of not fully penetrant SOD1 mutations.

OBJECTIVE: More than 180 different superoxide dismutase 1 (SOD1) mutations have been described to date in amyotrophic lateral sclerosis (ALS) patients, including not completely penetrant ones leading to phenotypic heterogeneity among carriers. We collected DNA samples from five ALS families with not fully penetrant SOD1 mutations (p.Asn65Ser, p.Gly72Ser, p.Gly93Asp, and p.Gly130_Glu133del) searching for epigenetic differences among ALS patients, asymptomatic/paucisymptomatic carriers and non-carrier family members. METHODS: Global DNA methylation levels (5-methylcytosine levels) were determined in blood DNA samples with an enzyme-linked immunosorbent assay (ELISA), and the methylation analysis of SOD1, FUS, TARDBP and C9orf72 genes was performed using Methylation-Sensitive High-Resolution Melting (MS-HRM) technique. RESULTS: Global DNA methylation levels were significantly higher in blood DNA of ALS patients than in asymptomatic/paucisymptomatic carriers or family members non-carriers of SOD1 mutations, and a positive correlation between global DNA methylation levels and disease duration (months) was observed. SOD1, FUS, TARDBP and C9orf72 gene promoters were demethylated in all subjects. CONCLUSIONS: The present study suggests that global changes in DNA methylation might contribute to the ALS phenotype in carriers of not fully penetrant SOD1 mutations, thus reinforcing the role of epigenetic factors in modulating the phenotypic expression of the disease.
