RESUMO

The recovery of the polyol component, after glycolysis of polyurethane (PU) foams coming from automotive waste, was investigated. Several separation methods such as simple sedimentation, centrifugation and liquid-liquid extraction, eventually preceded by an acid washing step, were tested. The obtained fractions were characterized by infrared spectroscopy and CHN elemental analysis. Furthermore, multivariate data analysis was carried out on the infrared spectra by principal component analysis to classify the fractions based on purity. IR spectroscopy coupled with principal component analysis was able to estimate the success of the separation and eventual culprits such as contaminations, which were then quantified by CHN elemental analysis. This approach addresses some critical limitations associated with classical analytical techniques such as NMR, TGA, GPC, MALDI-TOF that often require an extremely accurate separation of the depolymerized product fractions. Moreover, IR spectroscopy and CHN elemental analysis techniques are cheap and widespread in standard materials science laboratories. At last, based on the results of the analysis of the regenerated polyol fractions, and on the foaming tests, considerations were made to guide the choice of the purification method according to the application specifications and greenness.

RESUMO

Negative pressure wound therapy (NPWT) is a wound-dressing system that applies sub-atmospheric pressure on the surface of a wound to promote healing. An evolution of this technology, NPWT with solution instillation and dwell time (NPWTi-d), is increasingly being used to maximise wound closure and reduce failure rates. However, there is still a lack of evidence concerning its use in orthoplastic surgery. Therefore, the aim of this study is to compare NPWTi-d with NPWT and standard of care for wound management in orthoplastic surgery. A comprehensive literature search using PubMed, Web of Science, and Cochrane databases up to 15 March 2022 was performed, including studies describing the outcomes of NPWTi-d for traumatic/orthopaedic injuries. A meta-analysis on the number of surgical debridements, as well as the rate of complete wound closure and complications was carried out, although for other outcomes, a descriptive statistic was applied. Risk of bias and quality of evidence were assessed using the Downs& Black's Checklist for Measuring Quality. Thirteen studies with a total number of 871 patients were included, in which NPWTi-d demonstrated significantly higher primary wound closure and lower complication rates (P < .05). No difference in the number of surgical procedures required for final wound healing was observed. Moreover, five out of six studies showed better results for NPWTi-d when the change of the bioburden and bacterial count of the wound were analysed. A singular study investigating the length of the hospital stay of patients treated with NPWTi-d showed a reduction in the latter. The present meta-analysis proves that NPWTi-d is superior to NPTW or conventional dressings in orthoplastic wound care management, in terms of complete wound closure rate and the reduced number of complications. Still, the limited quality of the studies analysed shows that future randomised studies are needed to confirm the benefits and to identify the most appropriate recommendations for using NPWTi-d in orthoplastic surgery, as well as to investigate the cost-effectiveness of this wound-dressing system.

RESUMO

BACKGROUND AND AIMS: Cholangiocarcinoma (CCA) is a very aggressive cancer showing the presence of high cancer stem cells (CSCs). Doublecortin-like kinase1 (DCLK1) has been demonstrated as a CSC marker in different gastroenterological solid tumors. Our aim was to evaluate in vitro the expression and the biological function of DCLK1 in intrahepatic CCA (iCCA) and perihilar CCA (pCCA). APPROACH AND RESULTS: Specimens surgically resected of human CCA were enzymatically digested, submitted to immunosorting for specific CSC markers (LGR5 [leucine-rich repeat-containing G protein-coupled receptor], CD [clusters of differentiation] 90, EpCAM [epithelial cell adhesion molecule], CD133, and CD13), and primary cell cultures were prepared. DCLK1 expression was analyzed in CCA cell cultures by real-time quantitative PCR, western blot, and immunofluorescence. Functional studies have been performed by evaluating the effects of selective DCLK1 inhibitor (LRRK2-IN-1) on cell proliferation (MTS [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium] assay, cell population doubling time), apoptosis, and colony formation capacity. DCLK1 was investigated in situ by immunohistochemistry and real-time quantitative PCR. DCLK1 serum concentration was analyzed by enzyme-linked immunosorbent assay. We describe DCLK1 in CCA with an increased gene and protein DCLK1 expression in pCCALGR5+ and in iCCACD133+ cells compared with unsorted cells. LRRK2-IN-1 showed an anti-proliferative effect in a dose-dependent manner. LRRK2-IN-1 markedly impaired cell proliferation, induced apoptosis, and decreased colony formation capacity and colony size in both iCCA and pCCA compared with the untreated cells. In situ analysis confirmed that DCLK1 is present only in tumors, and not in healthy tissue. Interestingly, DCLK1 was detected in the human serum samples of patients with iCCA (high), pCCA (high), HCC (low), and cirrhosis (low), but it was almost undetectable in healthy controls. CONCLUSIONS: DCLK1 characterizes a specific CSC subpopulation of iCCACD133+ and pCCALGR5+ , and its inhibition exerts anti-neoplastic effects in primary CCA cell cultures. Human DCLK1 serum might represent a serum biomarker for the early CCA diagnosis.

RESUMO

The fetal liver is unique because of the coexistence of cells with endodermal and mesenchymal origins, making it a potential source of hepatic and pancreatic regenerative medicine. The liver appears at about the third week of gestation, growing rapidly from the fifth to the 10th week. We define fetal liver from 10 weeks of gestation, when hematopoietic progenitor cells gradually migrate from the aorta-mesonephros-gonad region to colonize the liver. Indeed, the fetal liver may be the most available source of cell therapy for liver disease. We conducted a review of the literature using Medline and EMBASE (up to May 2021) to identify clinical studies in which patients with liver disease had been given fetal liver cell therapy. This literature review highlighted the heterogeneity of cell isolation and selection protocols, which hinders the ability to pool data and perform a meta-analysis. A limitation of the studies analyzed was the scarcity of reports (n = 8) and the extremely small sample sizes (median sample size of treated patients was two), although there was a fairly long follow-up (median 12 months). The weeks after conception ranged from 16 to 34. There were no randomized controlled trials, and therefore no study was stratified as being of good methodological quality. Cryopreservation may help to circumvent the critical logistic issues that hamper the use of fetal liver cell therapy in clinical practice. To help consolidate the role of the fetal liver in regenerative medicine, good preclinical translational studies are necessary, whereas tracing strategies and biopsy-based endpoints are crucial in the clinic, along with well-designed, large, multicenter, randomized controlled trials using clinically applicable primary outcomes and refined imaging assessment.

RESUMO

Patients with metastatic and recurrent cervical cancer (CC) have a poor prognosis with limited palliative treatment options. Increasing understanding of the cellular aberrations inherent to cancer cells has allowed the development of therapies to target biological pathways, an important step toward the individualization of cancer therapy. The poly (ADP-ribose) polymerase (PARP) family of enzymes is important in several DNA repair pathways. Drugs that inhibit these PARP enzymes have been investigated in many types of cancer and their application in the treatment of gynecologic malignancies has rapidly evolved. Although the majority of data for PARPi in gynecologic malignancies has been specifically regarding ovarian cancer, their role in the treatment of uterine and CC is currently being investigated. This review will examine PARP inhibitors in CC, summarizes the critical clinical trials of PARP inhibitors that have been completed, provides an overview of the on-going trials, presents the confirmed conclusions and notes the issues that need to be addressed in future studies.

RESUMO

Implementing the Ecosystem Approach in marine ecosystems is moving from preliminary steps-dedicated to defining the optimal features for indicators and developing efficient indicator frameworks-towards an operational phase where multisector marine management decisions are executed using this information. Within this operational context, emergent ecosystem properties are becoming quite promising as they have been demonstrated to be globally widespread and repeatable, and to be quite effective in detecting significant state variations of complex systems. Biomass accumulation across TLs (CumB-TL) combines two important emergent properties of an ecosystem (energy flow, in terms of transfer efficiency, and storage, expressed as biomass), both amenable to detecting rapid ecosystem change. However, for further application, it is crucial to understand which types of drivers an indicator is sensitive to and how robust it is in relation to modifications of the external conditions and/or the system state. Here we address some outstanding questions of these CumB-TL curves related to their sensitivity to various drivers by carrying out a global scale assessment (using data from 62 LMEs) over six decades (1950-2010). We confirm the consistency of the S-pattern across all the LMEs, independent from latitude, ecosystem, environmental conditions, and stress level. The dynamics of the curve shape showed a tendency to stretch (i.e. decrease of steepness), in the presence of external disturbance and conversely to increase in steepness and shift towards higher TL in the case of recovery from stressed conditions. Our results suggest the presence of three main types of ecosystem dynamics, those showing an almost continuous increase in ecological state over time, those showing a continuous decrease in ecological state over time, and finally those showing a mixed behaviour flipping between recovering and degrading phases. These robust patterns suggest that the CumB-TL curve approach has some useful properties for use in further advancing the implementation of the Ecosystem Approach, allowing us to detect the state of a given marine ecosystem based on the dynamics of its curve shape, by using readily available time series data. The value of being able to identify conditions that might require management actions is quite high and, in many respects, represents the main objective in the context of an Ecosystem Approach, with large applications for detecting and responding to global changes in marine ecosystems.

RESUMO

OBJECTIVE: To assess the efficacy and side effects of antibiotic prophylaxis compared with placebo or no treatment in women undergoing hysteroscopy. DATA SOURCES: A structured search was carried out in PubMed-Medline, Embase, and Cochrane Controlled Trials Register databases through December 31, 2018. METHODS OF STUDY SELECTION: The search included a combination of the following terms: "hysteroscopy," "endoscopic surgery," "antibiotic prophylaxis." The following outcomes were selected: postoperative fever, infection rate, pelvic inflammatory disease (PID) and abscess occurrence, postoperative antibiotic requirement, and side effects occurrence (lower abdominal pain, vomiting, diarrhea, anaphylactic reaction). A random-effects model was used at meta-analysis. Study quality and bias risk were assessed with the Cochrane tool. TABULATION, INTEGRATION, AND RESULTS: Five randomized controlled trials comparing efficacy of antibiotic prophylaxis with placebo or no treatment were included in the meta-analysis. Overall, pooled incidence of events was very low in both groups (fever, 3.79% vs 1.8%; overall infection, .52% vs .58%; postoperative antibiotic therapy, 1.18% vs 1.32%; and lower abdominal pain, 12.46% vs 9.31%). Moreover, the incidence of serious infections requiring further actions (PID or abscess) appeared to be extremely low (.2% in pretreated women and none in control groups). No one trial individually or the pooled analysis showed a statistically significant benefit of antibiotics prophylaxis over placebo for the outcome considered. CONCLUSION: The use of antibiotics appears not to be beneficial to prevent infection after hysteroscopy; however, the lack of high-quality studies makes it difficult to draw firm conclusions. Considering the very low infection rate highlighted after hysteroscopic procedures, a difference will probably never be proven in a randomized trial. A larger population and program data to confirm these results are therefore warranted.

RESUMO

The aim of this study is to evaluate the sexual functionality before and after treatment of Bartholin's gland diseases (BGD) with CO2 laser and to compare our results to patients who underwent surgical cold knife and to a healthy control group (HCG). Consecutive patients (n = 15) affected by BG cyst or abscess who underwent CO2 laser treatment were evaluated. Patients were asked to complete the Italian translation of the Female Sexual Functioning Index (FSFI) before and 4 weeks after treatment. Results after CO2 laser were compared with two control groups: patients affected by BG cyst (n = 15) or abscess treated with surgical cold knife treatment and a HCG (n = 18). A statistically significant advantage of CO2 laser versus cold knife treatment in terms of lubrication, pain and global score were recorded. Both the single scores of five domains and total score of FSFI were globally higher after any treatment compared to before (CO2 and cold knife) of BGD. According to our data, CO2 laser therapy is often well tolerated by patients and correlated with a favorable sexual health recovery.

RESUMO

The aim of this study was to assess the effectiveness and safety of Ospemifene in the improvement of urgency component in women affected by mixed urinary incontinence (MUI) who underwent surgery with mid-urethral sling (MUS). Eighty-one patients with MUI underwent surgical intervention with MUS were enrolled. After surgical intervention 38 patients received Ospemifene 60 mg one tablet daily per os for 12 weeks. Physical examination, 3-day voiding diary, urodynamic testing were performed at the start and the follow-up after 12 weeks in the Trans-Obturator-Tape (TOT)-Alone group and TOT-Ospemifene. Patients completed the Overactive Bladder Symptom and Health-Related Quality of Life Short-Form (OAB-Q SF), International Consultation on Incontinence Questionnaire (ICIQ-UI-SF), and King' s Health Questionnaire (KHQ). A significant difference between the two groups was observed in peak flow (ml/s), in first voiding desire (ml), in maximum cystometric capacity (ml), and in detrusor pressure at peak flow (cmH2O) at urodynamic evaluation. A significative difference between the two groups at voiding diary was observed in the mean number of voids, urgent micturition episodes/24 h, urge urinary incontinence, and in nocturia events. The OAB-Q symptoms and OAB-Q (HRQL) scores after 12 weeks showed a significative difference between the two groups. Ospemifene is an effective potential therapy after MUSs in women with MUI improving urgency symptoms and quality of life.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the immunohistochemical (IHC) expression of Ki-67, estrogen receptors α (ERsα), and progesterone receptors (PRs) in high-risk endometrial cancer patients and to assess their prognostic impact. METHODS/MATERIALS: Immunohistochemical expression of Ki-67, ERsα, and PRs was evaluated in primary untreated endometrial cancer. The correlation among IHC staining and risk factors of recurrence such as age, Federation International of Gynecology and Obstetrics stage, grading, depth of invasion, and metastatic spread was assessed. RESULTS: Eighty-two patients were available for the analysis. Mean ± SD age was 65.05 ± 10.48 years. The IHC assessment revealed a lack of ERα in 46.3% and of PR in 48.7% as well as a high Ki-67 in 31.7%. Loss of ERα and PR was associated with a significant higher rate of advanced stage of disease, a higher frequency of G3 tumors, and a myometrial invasion greater than 50%. A strong Ki-67 expression correlated with a deeper myometrial invasion. Analysis of the interrelationship between receptor immunonegativity revealed a relevant association of ERα immunolocalization with PR and with a high Ki-67 expression. The present study also showed that loss of ERα (P = 0.003), advanced Federation International of Gynecology and Obstetrics stage (P < 0.001), and high Ki-67 (P = 0.004) were independent prognostic factors of a shorter disease-free survival. Importantly, loss of ERα, loss of PR, and a high Ki-67 were correlated with a higher incidence of distant recurrence. CONCLUSIONS: A systematic immunohistochemistry should be a key step in the therapeutic algorithm and could contribute to the identification of high-risk tumors.

RESUMO

The aim of this study was to assess the effectiveness of ospemifene in the improvement of sexual function in postmenopausal women with vulvovaginal atrophy (VVA) affected by overactive bladder syndrome (OAB) or urge urinary incontinence (UUI). One hundred five postmenopausal patients with VVA affected by OAB and/or UUI were enrolled for the study. All patients received ospemifene 60 mg for 12 weeks. Clinical examination, 3-d voiding diary and the vaginal health index (VHI) were performed at baseline and at 12 weeks. Patients completed the OAB-Q SF, FSFI, FSDS, and SF-36 questionnaires. The patient's satisfaction was also calculated. After 12 weeks, the reduction of urinary symptoms was observed. The OAB-Q symptoms, OAB-Q (HRQL) score were (55.34 ± 13.54 vs. 23.22 ± 9.76; p < .0001) and (22.45 ± 9.78 vs. 70.56 ± 15.49; p < .0001), before and after treatment. SF-36 questionnaire showed a significant improvement (p < .0001). VHI score increased and the women who regularly practice sexual activity increased after treatment. The total FSFI score increased significantly and the FSDS score changed after 12 weeks (p < .0001). The PGI-I after 12 weeks showed a total success rate of 90.5%. Ospemifene is an effective potential therapy for postmenopausal women with VVA affected by OAB or UUI improving sexual function and quality of life.

RESUMO

OBJECTIVE: The aim of this study was to assess the efficacy and tolerability of trabectedin given every 10 days as a single agent in recurrent ovarian cancer after 3 prior regimens. METHOD: Trabectedin 0.6 mg/m2 was administered as a 3-h infusion every 10 days on a 21-day cycle. The study population was compared to patients treated with weekly paclitaxel 80 mg/m2 intravenously on days 1, 8, 15, and 22 every 4 weeks. RESULTS: We identified 34 patients previously submitted to at least 3 lines of chemotherapy who received single-agent trabectedin between 2010 and 2015. They were matched with a historical series of 34 patients who received weekly paclitaxel. No significant differences in response rate were found. Median progression-free survival was 4 months; 5 months in the trabectedin group and 4 months in the paclitaxel group. Overall survival (OS) was 13 months for the trabectedin group and 7 months for the paclitaxel group (p = 0.015). Patients who received platinum after trabectedin had a significant OS increase compared to those who received platinum after paclitaxel (18 vs. 9 months, respectively; p = 0.009). The most frequent drug-related grade 3/4 toxicities were reversible hepatic toxicity, neutropenia, anemia, thrombocytopenia, and gastrointestinal toxicity. CONCLUSION: Single-agent trabectedin every 10 days is an active treatment with a manageable toxicity profile in heavily pretreated advanced relapsed ovarian cancer patients.

RESUMO

Ovarian cancer is a most lethal gynecologic tumor. The mainstay treatment is cytoreductive surgery followed by platinum-based chemotherapy. However, a high percentage of patients recur, thus needing multiple treatments with a frequently poor prognosis. In the last two decades, research has focused on the potential of target therapies to improve the survival of patients affected by ovarian cancer. Bevacizumab is one of the most studied target therapies, and it is approved for first- and second-line treatment of advanced epithelial ovarian, fallopian tube, and primary peritoneal tumors. Despite its widespread use with favorable results, controversy regarding patient selection and the best schedule, dosage, and timing of bevacizumab still exists. This review summarizes the state of the art on the use of bevacizumab for ovarian cancer in front-line, recurrence, and neoadjuvant settings. This study focuses on the results of pivotal trials, emerging data, ongoing research, and still unanswered questions about the most adequate dosage of bevacizumab and its potential activity after disease progression or rechallenge in previously treated patients.

RESUMO

AIMS: The aim of this study was to assess the effectiveness and safety of ospemifene in the improvement of overactive bladder (OAB) symptoms in postmenopausal women affected by vulvovaginal atrophy (VVA). METHODS: Forty-six postmenopausal patients affected by VVA with OAB syndrome were enrolled for the study. All patients received Ospemifene 60 mg for 12 weeks. Clinical examination, 3-day voiding diary, urodynamic testing, ultrasound measurement of endometrial and bladder wall thickness (BWT) and the Vaginal Health Index (VHI) were performed at baseline and 12 weeks. Patients completed the OAB-Q SF and UDI-6. RESULTS: After 12-weeks, the number of patients with detrusor overactivity decreased from 39% to 13% (p = 0.04). The reduction in the mean number in 24 h of voids (9.57 ± 2.12 vs. 6.63 ± 1.22, p < 0.0001), urgent micturition episodes/24 h (5.63 ± 1.46 vs. 1.44 ± 1.31, p < 0.0001), nocturia episodes (3.17 ± 0.85 vs. 1.11 ± 1.18, p < 0.0001), urinary incontinence episodes/24 h (0.85 ± 0.96 vs. 0.33 ± 0.64, p = 0.003) was observed. The UDI-6, OAB-Q symptoms, OAB-Q (HRQL) scores were 8.95 ± 0.91 vs. 5.56 ± 1.40, 62.60 ± 14.70 vs. 20.08 ± 10.83 and 18.71 ± 7.41 vs. 79.45 ± 14.47 (p < 0.001) before and after 12 weeks. CONCLUSION: Ospemifene is an effective potential therapy for postmenopausal women with VVA improving OAB symptoms and quality of life.

RESUMO

AIMS: The aim of this study was to assess the effectiveness and safety of vaginal native tissue repair (VNTR) as a surgical treatment for severe pelvic organ prolapse (POP) and, second, to evaluate the impact on the quality-of-life (QoL) and sexual function. METHODS: Women with symptomatic POP (≥III stage according to POP Quantification System) with or without stress urinary incontinence (SUI) underwent VNTR. The clinical stage, 3-day voiding diary, and urodynamic testing were evaluated in the preoperative and postoperative times, respectively. The International Consultation on Incontinence Questionnaire-Urinary Incontinence Questionnaire Short Form (ICIQ-UI SF), the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form (PISQ-12), and the prolapse quality-of-life questionnaire (P-QoL) were administered. RESULTS: One hundred forty-six patients were recruited. The median follow-up was 48 months (36-63). Fifty-two women (36%) had a previous hysterectomy, and 16 (11%) had a previous prolapse/continence surgery. Preoperatively, 135 (92.5%), 109 (74.7%), and 98 (67.1%) patients had anterior, central, and posterior descent ≥III stage, respectively. Thirty-two patients (22%) had concomitant diagnosis of SUI. Median operative time was 85 min (37-154), and median postoperative hospital stay was 2 days (2-4). No intraoperative severe complications occurred. At the long-term follow-up, the subjective cure rate for prolapse was 97.3% and the objective cure rate was 91.1%. A significant improvement of ICIQ-UI SF, the P-QoL, and the PISQ-12 was recorded at the follow-up (p < 0.001). CONCLUSION: VNTR is effective, safe, and durable and improves POP-related symptoms and sexual function.

RESUMO

BACKGROUND: To assess the clinical efficacy and prognostic outcome of neoadjuvant chemotherapy (NACT) plus radical surgery (RS) as front line treatment in patients with FIGO stage III cervical cancer (CC). METHODS: In this retrospective study, 52 FIGO stage III CC patients treated from 2005 to 2015 were included. All patients received platinum-based chemotherapy. Patients reporting clinical response or stable disease after NACT underwent to RS and bilateral systematic pelvic lymphadenectomy with or without aortic lymphadenectomy or anterior exenteration. Patients with progressive disease underwent palliative management. RESULTS: After NACT, clinical response was observed in 23 patients (44 %): 4 (7.7 %) complete and 19 (36.5 %) partial responses, respectively. Also, 15 patients (28.8 %) had stable disease and 14 (26.9 %) showed disease progression. RS was performed in 40 cases (76.9 %): respectively, 28 (70 %) and 7 (17.5 %) underwent type C2 and D radical hysterectomy, while 5 patients (12.5 %) underwent anterior exenteration. At pathological evaluation, 23 patients (57.5 %) had positive pelvic nodes and 4 (10 %) also had positive aortic nodes. In 6 patients (15 %), moderate-severe (G3-G5) complications occurred. A total of 27 patients (67.5 %) received adjuvant therapy: 16 patients (40 %) received chemotherapy, 10 (25 %) received chemoradiation and 1 (2.5 %) received radiotherapy. Disease relapse occurred in 24 cases (60 %). After follow-up period of 60 months, the median OS of the whole population included was 37 months. Among the 40 surgically treated patients, median OS and DFS were 48 and 23 months, respectively. CONCLUSIONS: NACT plus RS represent a valid alternative with acceptable morbidity for patients with stage III CC.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the feasibility and safety of type B radical hysterectomy (RH) in the management of patients affected by locally advanced cervical cancer with favorable prognostic factors (tumor diameter <40 mm, negative nodes, or lymphovascular space involvement) and clinical response to neoadjuvant chemotherapy (NACT). METHODS: The data of women undergoing platinum-based NACT followed by RH plus bilateral systematic pelvic lymphadenectomy were collected. Patients undergoing type B RH (Group A) were compared with those undergoing type C RH (Group B); a propensity-matched comparison (1:1) was carried out to minimize selection biases. Postoperative complications were reported and 5-year survival outcomes were assessed using the Kaplan-Meier model. RESULTS: Thirty-six node-negative patients undergoing type B RH (Group A) were compared with 36 propensity-matched patients undergoing type C RH (Group B). The bladder dysfunction rate was significantly lower in Group A compared with Group B (13.9 vs. 69.4 %; p < 0.0001), and no statistically significant difference in 5-year overall survival (OS) and disease-free survival (DFS) between groups was reported (OS 93.0 vs. 96.7 %, p = 0.42; DFS 88.6 and 85.5 %, p = 0.77). CONCLUSIONS: Type B RH after NACT in well-selected patients is a safe procedure that upholds the results of type C, reducing operative time and late postoperative morbidity, without detrimental effect on survival. Further prospective trials are warranted to confirm our results on a large scale.

RESUMO

BACKGROUND: During the last decades many successful efforts have been made in order to increase life expectancy in ovarian cancer (OC) patients. However, just a few studies have investigated the impact of OC on quality of life (QoL) and sexual function in OC cases during treatment. OBJECTIVE: The aim of this study was to evaluate the QoL and sexual function of OC patients during chemotherapy (CT). PATIENTS AND METHODS: Forty-nine subjects were enrolled and filled in the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-OV28, Female Sexual Function Index (FSFI) and Female Sexual Distress Scale (FSDS) questionnaires. The results were evaluated globally and consequently stratified into several groups: single surgery versus multiple surgeries, age ≤48 years versus >48 years, and first-line CT versus multiple lines of CT. RESULTS: Menopause-related symptoms, body image and attitude toward the disease were significantly worse during first-line CT (p = 0.018, p = 0.029 and p = 0.006, respectively). Sexual outcomes resulted in better scores in younger patients in all questionnaires (FSFI: p = 0.001; FSDS: p = 0.048; specific EORTC QLQ-OV28 items: p = 0.022). Scores concerning body image, attitude toward the disease and CT-associated symptoms resulted worse in patients after the first surgery (p = 0.017, p = 0.002 and p = 0.012, respectively). CONCLUSION: Our study confirms that OC has a detrimental impact on QoL and intimacy, particularly in younger patients, during the first course of CT and after the first cytoreductive surgery.

RESUMO

BACKGROUND: Gigantomastia is a debilitating condition characterised by an excessive breast tissue growth impacting patients' quality of life. Surgically treatment options include the limited-length pedicle (LP) technique with free nipple grafting (FNG) and the elongated pedicle (EP) technique, which maintains continuity of the nipple-areola complex (NAC). Initially, despite the less satisfactory aesthetic outcome, FNG was preferred to treat hypertrophic breasts requiring resections over 1000 g of parenchymal and adipose tissue, due to concerns about NAC perfusion. Recently, many studies have questioned this indication. The aim of this study was therefore to evaluate the safety of the NAC-carrying EP technique in patients with gigantomastia eventually challenging the need for FNG. METHODS: A literature search using PubMed and Cochrane databases was performed, including studies describing the outcome of EP technique for resection exceeding 1000 g of breast tissue. Thereby, a meta-analysis was conducted to evaluate the rate of NAC necrosis, whereas a descriptive statistic was applied to assess all other surgery-associated complications. RESULTS: Twenty-five studies, encompassing 1355 patients (2656 breasts), were included. EP demonstrated an extremely low rate of NAC necrosis. Moreover, the analysis demonstrated a low rate of ischaemia-independent complications and a very high probability of maintaining NAC-sensation equal to the preoperative state. CONCLUSION: Current evidence indicates that the EP technique should be the preferred surgical method to treat gigantomastia with or without massive ptosis whenever indicated. It has proven to be safe. Furthermore, it yields superior aesthetic and functional outcomes, including breast feeding and preservation of NAC-sensation compared to the LP technique.
