RESUMO

Uterine leiomyomas (ULs) are non-cancerous tumors composed of smooth muscle cells that develop within the myometrium and represent the most prevalent pathological condition affecting the female genital tract. Despite the volume of available research, many aspects of ULs remain unresolved, making it a "paradoxical disease" where the increase in available scientific literature has not been matched by an increase in solid evidence for clinical management. Fertility stands at the top of the list of clinical issues where the role of ULs is still unclear. The leiomyoma subclassification system, released by the International Federaion of Gynecology and Obstetrics (FIGO) in 2008, introduced a new and more effective way of categorizing uterine fibroids. The aim was to go beyond the traditional classification "subserosal, intramural and submucosal", facilitating a detailed examination of individual ULs impact on the female reproductive system. The "type 3 UL" is a special type of myoma, characterized by its complete myometrial development while encroaching the endometrium. It is a unique "hybrid" between a submucous and an intramural UL, that may exert a detrimental "double hit" mechanism, which is of particular interest in patients wishing pregnancy. To date, no robust evidence is available regarding the management of type 3 ULs. The aim of this narrative review is to provide a comprehensive overview of the physiopathological mechanisms that type 3 UL may exert on fertility, and to present new perspectives that may help us to better understand both the need for and the methods of treating this unique type of fibroid.

RESUMO

Accumulating evidence suggests that oral supplementation with myo-Inositol (myo-Ins) is able to reduce the amount of gonadotropins and days of controlled ovarian hyperstimulation (COS) necessary to achieve adequate oocyte maturation in assisted reproduction technology (ART) protocols, particularly in women affected by polycystic ovary syndrome (PCOS). We used computational calculations based on simulation modellings. We simulated in vitro fertilization (IVF) procedures-with or without intracytoplasmic sperm injection (ICSI)-with 100,000 virtual patients, accounting for all the stages of the entire IVF procedure. A Monte Carlo technique was used to account for data uncertainty and to generate the outcome distribution at each stage. We considered virtual patients with PCOS undergoing IVF cycles to achieve pregnancy. Computational data were retrieved from clinical experience and published data. We investigated three parameters related to ART protocols: cost of single procedure; efficacy to achieve ongoing pregnancy at 12 gestational weeks; overall cost per single pregnancy. The administration of oral myo-Ins during COH protocols, compared to the standard COH with recombinant Follicle Stimulating Hormone (rFSH) only, may be considered a potential strategy to reduce costs of ART for the Italian Health System.

RESUMO

There is evidence that diet and nutrition are modifiable risk factors for several cancers. In recent years, attention paid to micronutrients in gynecology has increased, especially regarding Human papillomavirus (HPV) infection. We performed a review of the literature up until December 2022, aiming to clarify the effects of micronutrients, minerals, and vitamins on the history of HPV infection and the development of cervical cancer. We included studies having as their primary objective the evaluation of dietary supplements, in particular calcium; zinc; iron; selenium; carotenoids; and vitamins A, B12, C, D, E, and K. Different oligo-elements and micronutrients demonstrated a potential protective role against cervical cancer by intervening in different stages of the natural history of HPV infection, development of cervical dysplasia, and invasive disease. Healthcare providers should be aware of and incorporate the literature evidence in counseling, although the low quality of evidence provided by available studies recommends further well-designed investigations to give clear indications for clinical practice.

RESUMO

Human papillomavirus (HPV) infection is one the most common sexually transmitted infections worldwide. In most cases, the infection is temporary and asymptomatic; however, when persistent, it may lead to lesions that can evolve into cancer in both women and men. Nowadays, prophylactic vaccination is the primary preventive strategy for HPV infections, but vaccines do not cover all types of HPV strains. Scientific research has uncovered the beneficial role of some natural supplements in preventing persistent HPV infections or treating HPV-related lesions. We review the current insight into the roles of natural molecules in HPV infection with a special focus on epigallocatechin gallate (EGCG), folic acid, vitamin B12, and hyaluronic acid (HA). Specifically, EGCG from green tea extracts plays a critical role in suppressing HPV oncogenes and oncoproteins (E6/E7), which are responsible for HPV oncogenic activity and cancer development. Folic acid and vitamin B12 are essential vitamins for multiple functions in the body, and accumulating evidence suggests their importance in maintaining a high degree of methylation of the HPV genome, thus decreasing the likelihood of causing malignant lesions. HA, due to its re-epithelizing property, may prevent HPV virus entry in damaged mucosa and epithelia. Thereby, based on these premises, the combination of EGCG, folic acid, vitamin B12, and HA may be a very promising therapeutic approach to prevent HPV persistence.

RESUMO

The progressive improvement of lymphoma treatment has led to an important prolongation of patient survival and life expectancy. The principal international scientific societies of oncology now therefore recommend that long-term survivors of lymphoma join fertility programs. Specifically, fertile-age patients should be assisted by a multidisciplinary team, including specialists dedicated to fertility preservation in oncology, in order to support the completion of their reproductive project. In the general population, the use of Myo-Inositol and D-Chiro-Inositol (MI/DCI) has been demonstrated to be an effective choice to treat ovarian dysfunctions, with a consequent improvement in reproductive outcomes, so it may represent an adjuvant strategy for this purpose. We therefore conducted a pilot prospective case-control study to evaluate the potentialities of this nutritional supplement, with the aim of optimizing reproductive function in female long-term survivors of lymphoma. One group underwent oral supplementation with MI 1200 mg and DCI 135 mg per day for 12 months, compared with controls who underwent no treatment in the same period. After 12 months, FSH, LH, and progesterone levels, as well as oligomenorrhea and antral follicle count (AFC), were significantly improved in the MI/DCI group. In addition, a significantly higher mean value in FSH and LH and a significantly lower mean AFC value in the right ovary were observed in controls compared to the MI/DCI group. Despite the need for further investigation, MI/DCI could be considered a potential adjuvant strategy to restore ovarian function in female long-term survivors of lymphoma.

RESUMO

OBJECTIVE: To investigate the feasibility and determine the recommended pre-operative intensity-modulated radiotherapy (IMRT) dose of extended-field chemoradiation along with simultaneous integrated boost (SIB) dose escalation. METHODS: A radiation dose of 40 Gy over 4 weeks, 2 Gy/fraction, was delivered to the tumour and the lymphatic drainage (planning target volume, PTV3), which encompassed a volume larger than standard (common iliac lymphatic area up to its apex, in front of the L3 vertebra), concurrently with chemotherapy (cisplatin and 5-fluorouracil). Radiation dose was escalated to the pelvis (PTV2) and to the macroscopic disease (PTV1) with the SIB-IMRT strategy. Three dose levels were planned: Level 1 (PTV3: 40/2 Gy; PTV2: 40/2 Gy; PTV1: 45/2.25 Gy), Level 2 (PTV3: 40/2 Gy; PTV2: 45/2.25 Gy; PTV1: 45/2.25 Gy) and Level 3 (PTV3: 40/2 Gy; PTV2: 45/2.25 Gy; PTV1: 50/2.5 Gy). All treatments were delivered in 20 fractions. Patients were treated in cohorts of between three and six per group using a Phase I study design. The recommended dose was exceeded if two of the six patients in a cohort experienced dose-limiting toxicity within 3 months from treatment. RESULTS: 19 patients [median age: 46 years; The International Federation of Gynecology and Obstetrics (FIGO) stage IB2: 3, IIB: 10, IIIA-IIIB: 6] were enrolled. Median follow-up was 24 months (9-60 months). The most common grade 3/4 toxicity was gastrointestinal (GI) (diarrhoea, mucous discharge, rectal/abdominal pain). At Levels 1 and 2, only one grade 3 GI toxicity per level was recorded, whereas at Level 3, two grade 3 GI toxicities (diarrhoea, emesis and nausea) were recorded. CONCLUSION: The SIB-IMRT technique was found to be feasible and safe at the recommended doses of 45 Gy to PTV1 and PTV2 and 40 Gy to PTV3 in the pre-operative treatment of patients with locally advanced cervical cancer. Unfortunately, this complex technique was unable to safely escalate dose beyond levels already achieved with three-dimensional conformal radiotherapy technique given acute GI toxicity. ADVANCES IN KNOWLEDGE: A Phase I radiotherapy dose-escalation trial with SIB-IMRT technique is proposed in cervical cancer. This complex technique is feasible and safe at the recommended doses.

RESUMO

BACKGROUND: We provided a comprehensive analysis of rate, pattern, and severity of early and late postoperative complications in a very large, single-institution series of locally advanced cervical cancer (LACC) patients administered CT/RT plus radical surgery (RS). METHODS: A total of 362 consecutive LACC (FIGO stage IB2-IVA) patients were submitted to RS after CT/RT at the Gynecologic Oncology Unit of the Catholic University (Rome/Campobasso). At 4 weeks after CT/RT, patients were evaluated for objective response and triaged to radical hysterectomy and pelvic ± aortic lymphadenectomy. Surgical morbidity was classified according to the Chassagne's grading system. RESULTS: Most cases underwent type III-IV radical hysterectomy (N = 313, 86.5 %); pelvic lymphadenectomy was performed in all patients, while 116 patients (32.1 %) were also submitted to aortic lymphadenectomy. A total of 93 patients (25.7 %) experienced any grade postoperative complications, and 60 (16.6 %) had ≥grade 2 complications; grade 3-4 complications occurred in 21 patients (5.8 %). Of all early postoperative complications (N = 100), 31 (31.0 %) were urinary, 9 (9.0 %) were gastrointestinal, and 45 (45.0 %) were vascular. Of all late complications (N = 31), 20 (64.5 %) were urinary, 7 (22.6 %) gastrointestinal, and 2 (6.4 %) were vascular. Multivariate analysis showed that not complete clinical response to treatment retained an independent, unfavorable association with risk of development of postoperative morbidity, while advanced stage, and aortic lymphadenectomy showed only a borderline value. CONCLUSIONS: Failure to achieve clinical complete response to treatment and, to a lesser extent, more advanced stage, and aortic lymphadenectomy, were associated with a higher risk of developing any grade as well as ≥grade 2 complications.

RESUMO

BACKGROUND: The aim of this study is to report on the impact of neuromodulation to the superior hypogastric plexus in patients with bladder atonia secondary to pelvic surgery. METHODS: In 4 consecutive patients with bladder atonia secondary to pelvic surgery, we performed a laparoscopic implantation of a neurostimulator--LION procedure--to the entire superior hypogastric plexus. RESULTS: Of the 4 reported patients, 3 are able to partially void or empty their bladder. CONCLUSIONS: If the presented results could be obtained in further patients and maintained in long-term follow-up, the LION procedure to the superior hypogastric plexus could change the management of bladder function in patients with bladder atonia.

RESUMO

BACKGROUND: We investigated the feasibility and advantages of introducing Laparoscopic Neuro-Navigation (LANN) into the field of laparoscopic gynecologic radical pelvic surgery. STUDY DESIGN: In a prospective pilot study, 261 consecutive patients underwent laparoscopic radical pelvic surgery for cervical cancer or deep infiltrating endometriosis of the parametria. During the procedure, dissection and electrostimulation, and consequently, sparing of the pelvic parasympathetic nerves by transection of the parametria, were performed. Postoperative bladder dysfunction was documented. RESULTS: Laparoscopic dissection and electrostimulation of the pelvic splanchnic nerves were feasible in all patients without any complications, and the rate of postoperative bladder dysfunction was considerably reduced, to less than 1% of the patients. CONCLUSIONS: The parasympathetic nerve-sparing method using the Laparoscopic Neuro-Navigation technique in laparoscopic radical pelvic gynecologic surgery is a feasible and reproducible technique that preserves postoperative bladder function.

RESUMO

OBJECTIVE: To evaluate the effects of soy isoflavone administration on endothelial function in healthy postmenopausal women. DESIGN: Sixty naturally postmenopausal women were randomly assigned to receive isoflavone or placebo tablets for 6 months. Endothelium-dependent vasodilatation was measured by brachial reactivity technique along with levels of plasma soluble intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin, P-selectin and soluble thrombomodulin, von Willebrand factor, and tissue plasminogen activator. Differences between endothelium-dependent and endothelium-independent vasodilatation were assessed by evaluating brachial reactivity parameters after reactive hyperemia and after sublingual administration of nitroglycerin; furthermore, in the active group, the effect of isoflavones was also evaluated during the intra-arterial infusion of N-monomethyl-L-arginine. Serum levels of lipids [high-density lipoprotein and low-density lipoprotein cholesterol, triglycerides and lipoprotein(a)] and hemostatic factors (prothrombin, fibrinogen, plasminogen activator inhibitor-1, and fibrin D-dimer) were also measured. To confirm the absorption of isoflavones, their blood concentrations were determined. RESULTS: Isoflavone treatment versus placebo was associated with a significant improvement in endothelium-dependent vasodilatation but had no impact on endothelial-independent arterial diameter and flow. Intra-arterial infusion of N-monomethyl-L-arginine inhibited the significant effect of isoflavones on endothelium-mediated vasodilatation. Furthermore, isoflavone group experienced statistically significant reductions in plasma concentrations of ICAM-1, VCAM-1, and E-selectin. Levels of soluble thrombomodulin, von Willebrand factor, tissue plasminogen activator, lipids, and hemostatic factors did not change significantly throughout the study in both groups. CONCLUSIONS: Our findings suggest a positive influence of soy isoflavones on endothelial function in healthy postmenopausal women as evidenced by an improvement in endothelium-dependent vasodilatation and a reduction in plasma adhesion molecule levels.

RESUMO

OBJECTIVE: To compare the long-term effects of oral and transdermal hormone replacement therapy (HRT) on serum homocysteine levels in postmenopausal women. DESIGN: An open, prospective, controlled study. Seventy-five healthy postmenopausal women were recruited as eligible for the study. Fifty women seeking HRT were randomized to receive continuous 17beta-estradiol, either by oral (2 mg daily; n = 25) or transdermal (50 microg daily; n = 25) administration, plus 10 mg dydrogesterone daily for 14 days of each 28-day cycle. Twenty-five women unwilling to receive hormone treatment received only calcium supplementation, representing the control group. Fasting blood samples were analyzed at baseline and then after 6, 12, and 24 months to determine plasma homocysteine levels. RESULTS: Fifty-nine women completed the study. After 6 months of therapy, homocysteine concentrations showed a statistically significant reduction in the treated groups versus both baseline and controls, and no further significant variations were found thereafter. The mean reduction in the homocysteine levels throughout the study was 13.6% in the oral and 8.9% in the transdermal group, respectively, without significant difference between the two routes of estradiol administration. Women with the highest baseline levels of homocysteine experienced the greatest reduction. No significant variations in homocysteine concentrations were found in the control group. CONCLUSIONS: Oral and transdermal estradiol sequentially combined with dydrogesterone shows comparable effectiveness in reducing plasma homocysteine levels in postmenopausal women. Women with the highest pretreatment concentrations of homocysteine benefit the most by the lowering effect of HRT.
