RESUMO

In the last few years, substantial progress has been made in the treatment of ovarian cancer, with increased knowledge about the biology of the disease. Ovarian cancer is a neoplasm strongly linked to defects in DNA repair mechanisms, where deficiency in the homologous recombination (HR) system results in a better response of ovarian cancers to therapy, whether platinum-based chemotherapy, anthracyclines, or poly (ADP-ribose) polymerase (PARP) inhibitors. More recently, it has been demonstrated that different ovarian cancer histotypes may have different immunogenicity. Interestingly, defects in HR systems are associated more frequently with higher tumor infiltrating lymphocytes, providing a rationale for developing combination therapy with immune-modulating agents and PARP inhibitors. Again, locoregional therapies combining heat shock and chemotherapy delivery have been shown to induce an anticancer immune response in vitro. Thus, the potential for locoregional therapeutic approaches that may impact the immune system, perhaps in combination with immune-modulating agents or PARP inhibitors, needs to be further explored. With this premise, we reviewed the main biological and clinical data demonstrating a strict interplay between the immune system, DNA repair mechanisms, and intraperitoneal therapies in ovarian cancer, with a focus on potential future therapeutic implications.

RESUMO

BACKGROUND: The purpose of this study was to evaluate the clinical impact of oxaliplatin, leucovorin, and 5-fluorouracil (FOLFOX-4) chemotherapy in terms of the response rate, progression-free/overall survival (PFS/OS) and safety profile in patients with heavily pretreated recurrent epithelial ovarian cancer. METHODS: Clinical data were reviewed in 29 patients who received FOLFOX-4 as more than third-line chemotherapy, consisting of 85 mg/m2 of oxaliplatin, 200 mg/m2 of leucovorin, and bolus 400 mg/m2 on day 1 of 5-fluorouracil, followed by a 22-h infusion of 600 mg/m2 of 5-fluorouracil for 2 consecutive days every 3 weeks. We also compared the efficacy and toxicity of FOLFOX-4 with that of topotecan, a standard treatment, given at a dosage of 1.5 mg/m2 every three weeks in 26 patients. RESULTS: The median age of enrolled patients was 60 years (range 33 to 85). A median of 4 cycles (range 1-17) of FOLFOX-4 were administered. Complete response and partial response were observed in one (3.5%) and 5 (17.2.2%) patients, respectively, while stable disease was reported in 8 (27.6%) patients. Among all patients, grade 3-4 anemia, neutropenia, and thrombocytopenia were observed in 0 (0%), 5 (17.2%), and 3 (10.3%) cases, respectively. Grade 3-4 fatigue was recorded in one (3.4%) patient and diarrhea in 2 (6.9%). Median PFS and OS were 2.8 months [95% confidence interval (CI) 1.7-4.9] and 6.2 months (95% CI 2.4-14.6), respectively. No significant differences in terms of efficacy and toxicity were observed between patients receiving FOLFOX-4 and those treated with topotecan. CONCLUSIONS: The FOLFOX-4 regimen would seem to obtain similar survival rates to those of standard therapy with topotecan in platinum-resistant ovarian cancer. Further randomized trials are warranted to confirm our findings.

RESUMO

OBJECTIVES: Amplification of human telomerase is known to be associated with cervical tumorigenesis, although its role in tumor progression of cervical lesions is still unclear. We aimed to evaluate the role of telomerase in predicting the evolution of cervical lesions. METHODS: A total of 50 tissue samples taken by biopsy or conization once or repeatedly from 17 patients with cervical lesions over a 14-year follow-up was analyzed using fluorescence in situ hybridization (FISH) for hTERC gene alterations and immunohistochemistry (IHC) for hTERT expression. The accuracy of the biomarkers was measured using the area under the curve. RESULTS: Telomerase gene amplification is highly indicative of cervical lesion evolution and seems to be a more reliable biomarker than the protein expression detected by IHC. In fact, patients with benign lesions or cervical intraepithelial lesions (CINs) showing hTERC amplification relapsed or progressed into CIN 2 and CIN 3 more frequently than those without any gene amplification. FISH and IHC assays had both 86% sensitivity on conized material and 78% and 40% specificity, respectively. CONCLUSIONS: We demonstrated that the most accurate method to evaluate telomerase alterations as prognostic markers in cervical lesions was FISH assay on hTERC gene. The best accuracy was obtained using conized materials.

RESUMO

BACKGROUND: The aim of this paper was to understand the role of prophylaxis with levetiracetam at skin incision in preventing convulsive intraoperative seizures (IOS) during neurosurgical procedures with and without intraoperative neuromonitoring (IONM). METHODS: Authors retrospectively reviewed the Institutional database for cases of supratentorial brain tumors undergoing surgical resection performed from January 2021 to October 2022. Patients were operated on both under general anesthesia and awake, using motor-evoked potentials (MEP) and direct cortical stimulation for cortical mapping. 1000 mg ev of Levetiracetam before skin incision in case of a history of seizures was administrated. We excluded all infratentorial cases. RESULTS: Three hundred fisty three consecutive cases were retrieved. IOS occurred in 22 patients (6.2%). Prophylaxis with Levetiracetam was administered in 149 patients, and IOS occurred in 16 cases (10.7%) in this group of patients. The IOS rate in the case of no Levetiracetam prophylaxis administration (3.5%) was significantly lower (P<0.001, OR=3.38 [1.35-8.45], RR=3.12 [1.32-7.41]). The Penfield technique stimulation evoked seven of all 22 IOS reported (31.8%) (P=0.006, RR 5.4 [1.44 -20.58], OR 21 [2.3-183.9]), and the train-of-five technique stimulation caused two of all registered IOS (8.7%) (P=0.2, RR 2.3 [0.99-5.67], OR 6.5 [0.55-76.17]). Transcranial MEPs evoked no IOS. CONCLUSIONS: Under levetiracetam prophylaxis, the IOS rate was not significantly lower than in the group of patients without Levetiracetam prophylaxis, regardless of the histology of the tumor and IONM. Neither the transcranial stimulation (MEP) nor train-of-five technique stimulation increases the risk of convulsive IOS, as Penfield technique stimulation does.

RESUMO

OBJECTIVE: The onco-functional balance represents the primary goal in neuro-oncology. The increasing use of navigated transcranial magnetic stimulation (nTMS) allows the noninvasive characterization of cortical functional anatomy, and its reliability for motor and language mapping has previously been validated. Calculation and arithmetic processing has not been studied with nTMS so far. In this study, the authors present their preliminary data concerning nTMS calculation. METHODS: The authors designed a monocentric prospective study, adopting an internal protocol to use nTMS for preoperative planning, including arithmetic processing. When awake surgery was possible, according to the patients' conditions, nTMS points were used to guide direct cortical stimulation (DCS), i.e., the gold standard for cortical mapping. Navigated TMS-based tractography was used for surgical planning. Statistical analyses on the nTMS and DCS points were performed. RESULTS: From February 2021 to October 2023, 61 procedures for nTMS calculation mapping were performed. The clinical evaluation, including pre- and postoperative evaluations (3 months after surgery), demonstrated a good clinical outcome with preservation of arithmetic function and recovery (92.8% of patients). Between the awake and asleep surgery groups, the postoperative clinical results were comparable at the 3-month follow-up, with > 90% of the patients achieving improved calculation function. The surgical strategy adopted was aimed at sparing nTMS positive points in asleep procedures, whereas nTMS and DCS positive points were not removed in awake procedures. Overall, 62% of the positive points for calculation functions were exposed by craniotomy and 85% were spared during surgery. None of the patients developed nTMS-related seizures. Diffusion tensor imaging fiber tracking based on nTMS positive points for calculation was used. The white matter fiber tracts involved in calculation functions were the arcuate fasciculus (56%) and frontal aslant tract (22%). When nTMS and DCS points were compared in awake surgery (n = 10 patients), a sensitivity of 31.71%, specificity of 85.76%, positive predictive value of 22.41%, negative predictive value of 90.64%, and accuracy of approximately 69% were achieved. CONCLUSIONS: Based on the authors' preliminary data, nTMS can be an advantageous tool to study cognitive functions, aimed at minimizing neurological impairment. The postoperative clinical outcome for patients who underwent operation with nTMS was very good. Considering these results, nTMS has proved to be a feasible method to map cognitive areas including those for calculation functions. Further analyses are needed to validate these data. Finally, other cognitive functions (e.g., visuospatial) may be explored with nTMS.

RESUMO

OBJECTIVE: The present study aimed to assess long-term follow-up outcomes in women with in situ/microinvasive adenocarcinoma (AC) of the uterine cervix treated conservatively. METHODS: Retrospective multi-institutional study including women with early glandular lesions and 5-year follow-up undergoing fertility-sparing treatment. Independent variables associated with recurrence were evaluated. Logistic regression analysis and Kaplan-Meier survival analysis with Logrank test were performed. RESULTS: Of 269 women diagnosed with in situ/microinvasive AC, 127 participants underwent conservative treatment. During follow-up, recurrences were found in nine women (7.1%). The only factor associated with recurrence during follow-up was positive high-risk Human Papillomavirus (hr-HPV) testing (odds ratio 6.21, confidence interval 1.47-26.08, p = 0.012). HPV positivity in follow-up showed a recurrence rate of 21.7% against 3.8% in patients who were HPV-negative (p = 0.002, Logrank test). Among women with negative high-risk HPV tests in follow-up, recurrences occurred in 20.0% of non-usual-type histology vs. 2.1% of usual-type cases (p = 0.005). CONCLUSION: HPV testing in follow-up is of pivotal importance in women with early glandular lesions undergoing conservative treatment, given its recurrence predictive value. However, women who are high-risk HPV-negative in follow-up with non-usual-type histopathology may represent a sub-population at increased risk of recurrences. Further studies should confirm these findings.

RESUMO

OBJECTIVE: The aim of the present study was to determine the position of the 3 sensory branches of the trigeminal nerve in the preganglionic tract using intraoperative neurophysiological mapping. METHODS: We included consecutive adult patients who underwent neurosurgical treatment of cerebellopontine angle lesions. The trigeminal nerve was antidromically stimulated at 3 sites along its circumference with different stimulus intensities at a distance of ≤1 cm from the brainstem. The sensory nerve action potentials (SNAPs) were recorded from each main trigeminal branch (V1 [ophthalmic branch], V2 [maxillary branch], and V3 [mandibular branch]). RESULTS: We analyzed 13 patients. The stimulation points at which we obtained the greatest number of congruous and exclusive SNAPs (SNAPs only on the stimulated branch) was the stimulation point for V3 (20.7%). The stimulation intensity at which we obtained the highest number of congruent and exclusive SNAPs with the stimulated branch was 0.5 mA. CONCLUSIONS: Using our recording conditions, trigeminal stimulation is a reliable technique for mapping the V3 and V1 branches using an intensity not exceeding 0.5. However, reliable identification of the fibers of V2 is more difficult. Stimulation of the trigeminal nerve can be a reliable technique to identify the V3 and V1 branches if rhizotomy of these branches is necessary.

RESUMO

OBJECTIVE: The role of visual evoked potentials (VEPs) monitoring during neurosurgical procedure in patient remains unclear. The purpose of our study was to determine the feasibility of intraoperative VEP recording using a strip cortical electrode during surgical resection of intracranial lesions. METHODS: In this prospective, monocentric, observational study, we enrolled consecutive patients undergoing neurosurgical procedure for intracranial lesions. After dural opening, a cortical strip was positioned on the lateral occipital surface. Flash VEPs were continuously recorded using both subdermal corkscrew electrodes and strip electrodes. An electroretinogram was also recorded to guarantee delivery of adequate flash stimuli to the retina. RESULTS: We included 10 patients affected by different intracranial lesions. Flash VEPs were recorded using subdermal corkscrew electrodes in all patients except 1 in whom they were never identified during the recording. Flash VEPs were recorded using strip electrodes in all patients and showed a polyphasic morphology with a significantly larger amplitude compared with that of flash VEPs measured using subdermal corkscrew electrodes. No patient reported worsened postoperative vision and a >50% decrease in the VEPs amplitude was never registered. CONCLUSIONS: We have reported for the first time in the literature that VEP monitoring during a neurosurgical procedure is feasible via a cortical strip located on the occipital surface. The technique demonstrated greater stability and a larger amplitude compared with recordings with scalp electrodes, facilitating identification of any changes. Studies with more patients are needed to assess the clinical reliability of the technique.

RESUMO

BACKGROUND: Patient State Index (PSI) and Suppression Ratio (SR) are two indices calculated by quantitative analysis of EEG used to estimate the depth of anaesthesia but their validation in neurosurgery must be done. Our aim was to investigate the congruity PSI and SR with raw EEG monitoring in neurosurgery. METHODS: We included 34 patients undergoing elective cranial neurosurgery. Each patient was monitored by a SedLine device (PSI and SR) and by raw EEG. To appraise the agreement between PSI, SR and EEG Suppr%, Bland-Altman analysis was used. We also correlated the PSI and SR recorded at different times during surgery to the degree of suppression of the raw EEG data by Spearman's rank correlation coefficient. For a comparison with previous data we made an international literature review according to PRISMA protocol. RESULTS: At all recording times, we found that there is a strong agreement between PSI and raw EEG. We also found a significant correlation for both PSI and SR with the EEG suppression percentage (p < 0.05), but with a broad dispersion of the individual values within the confidence interval. CONCLUSION: The Masimo SedLine processed EEG monitoring system can be used as a guide in the anaesthetic management of patients during elective cranial neurosurgery, but the anaesthesiologist must be aware that previous correlations between PSI and SR with the suppression percentage may not always be valid in all individual patients. The use of an extended visual raw EEG evaluated by an expert electroencephalographer might help to provide better guidance.

RESUMO

Introduction: Primary debulking surgery (PDS), interval debulking surgery (IDS), and platinum-based chemotherapy are the current standard treatments for advanced ovarian cancer (OC). The time to initiation of adjuvant chemotherapy (TTC) could influence patient outcomes. Methods: We conducted a multicenter retrospective cohort study of advanced (International Federation of Gynecology and Obstetrics (FIGO) stage III or IV) OC treated between 2014 and 2018 to assess progression-free survival (PFS) and overall survival (OS) in relation to TTC. All patients underwent a germline multigene panel for BRCA1/2 evaluation. Results: Among the 83 patients who underwent PDS, a TTC ≥ 60 days was associated with a shorter PFS (hazard ratio (HR) 2.02, 95% confidence interval (CI) 1.04-3.93, p = 0.038), although this association lost statistical significance when adjusting for residual disease (HR 1.52, 95% CI 0.75-3.06, p = 0.244, for TTC and HR 2.73, 95% CI 1.50-4.96, p = 0.001, for residual disease). Among 52 IDS patients, we found no evidence of an association between TTC and clinical outcomes. Ascites, type of chemotherapy, or germline BRCA1/2 mutational status did not influence TTC and were not associated with clinical outcomes in PDS or IDS patients. Discussion: In conclusion, longer TTC seems to negatively affect prognosis in patients undergoing PDS, especially those with residual disease.

RESUMO

OBJECTIVE: To evaluate the impact of healthcare reorganization during the severe acute respiratory syndrome coronavirus 2 pandemic on Italian colposcopy clinic activities, focusing on cervical excision procedures, follow-ups for conservative management of low-grade lesions, and follow-ups post cervical excision. METHODS: Retrospective study conducted in 14 Italian colposcopy clinics. The number and clinical characteristics of cervical excisions, follow-ups for conservative management of low-grade lesions, and follow-ups after cervical excision were compared between the period March 1, 2019 to February 29, 2020 (pre-pandemic) and March 1, 2020 to February 28, 2021 (pandemic) with a Poisson regression analysis. RESULTS: In the pandemic period, the number of cervical excisions was reduced by 8.8% (95% confidence interval [CI]=-15.6% to -2%; p=0.011). Excisions were less frequently performed in the operating room (-35.1%; 95% CI=-47.6% to -22.6%; p<0.001), the number of patients from spontaneous screening was reduced by -14.0% (95% CI=-23.4% to -4.6%; p=0.003), and the CO2-laser technique was used less frequently (-30%; 95% CI=-45.1% to -15.0%; p<0.001). As compared to the pre-pandemic period, the number of follow-ups for conservative management of low-grade lesions was reduced by -26.7% (95% CI=-39.0% to -14.4%; p<0.001), and the follow-up appointments after cervical excision were reduced by -51.0% (95% CI=-58.1% to -43.9%; p<0.001). CONCLUSION: The most significant impact of the healthcare reorganization during the coronavirus disease 2019 pandemic was on follow-ups after cervical excision. The resumption of disrupted activities should follow a risk-based prioritization, starting from women in follow-up after cervical excision. It is advisable that the trend of performing cervical excision as an outpatient procedure is maintained in the post-pandemic period.

RESUMO

It is unknown whether human papillomavirus (HPV) status impacts the prognosis of early stage cervical glandular lesions. This study assessed the recurrence and survival rates of in situ/microinvasive adenocarcinomas (AC) according to HPV status during a 5-year follow-up. The data were retrospectively analyzed in women with available HPV testing before treatment. One hundred and forty-eight consecutive women were analyzed. The number of HPV-negative cases was 24 (16.2%). The survival rate was 100% in all participants. The recurrence rate was 7.4% (11 cases, including four invasive lesions (2.7%)). Cox proportional hazards regression showed no difference in recurrence rate between HPV-positive and HPV-negative cases (p = 0.148). HPV genotyping, available for 76 women and including 9/11 recurrences, showed a higher relapse rate for HPV-18 than HPV-45 and HPV-16 (28.5%, 16.6%, and 9.52%, p = 0.046). In addition, 60% and 75% of in situ and invasive recurrences, respectively, were HPV-18 related. The present study showed that most ACs were positive for high-risk HPV, and the recurrence rate was unaffected by HPV status. More extensive studies could help evaluate whether HPV genotyping may be considered for recurrence risk stratification in HPV-positive cases.

RESUMO

OBJECTIVE: Although standard treatment for advanced epithelial ovarian cancer (EOC) consists of surgical debulking and intravenous platinum- and taxane-based chemotherapy, favorable oncological outcomes have been recently reported with the use of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The aim of the study was to analyze feasibility and results of CRS and HIPEC in patients with advanced EOC. MATERIALS/METHODS: This is an open, prospective phase 2 study including patients with primary or recurrent peritoneal carcinomatosis due to EOC. Thirty-nine patients with a mean (SD) age of 57.3 (9.7) years (range, 34-74 years) were included between September 2005 and December 2009. Thirty patients (77%) had recurrent EOC and 9 (23%) had primary EOC. RESULTS: For HIPEC, cisplatin and paclitaxel were used for 11 patients (28%), cisplatin and doxorubicin for 26 patients (66%), paclitaxel and doxorubicin for 1 patient (3%), and doxorubicin alone for 1 patient (3%). The median intra-abdominal outflow temperature was 41.5°C. The mean peritoneal cancer index (PCI) was 11.1 (range, 1-28); and according to the intraoperative tumor extent, the tumor volume was classified as low (PCI <15) or high (PCI ≥15) in 27 patients (69%) and 12 patients (31%), respectively. Microscopically complete cytoreduction was achieved for 35 patients (90%), macroscopic cytoreduction was achieved for 3 patients (7%), and a gross tumor debulking was performed for 1 patient (3%). Mean hospital stay was 23.8 days. Postoperative complications occurred in 7 patients (18%), and reoperations in 3 patients (8%). There was one postoperative death. Recurrence was seen in 23 patients (59%) with a mean recurrence time of 14.4 months (range, 1-49 months). CONCLUSIONS: Hyperthermic intraperitoneal chemotherapy after extensive CRS for advanced EOC is feasible with acceptable morbidity and mortality. Complete cytoreduction may improve survival in highly selected patients. Additional follow-up and further studies are needed to determine the effects of HIPEC on survival.

RESUMO

BACKGROUND: Tumours of the anterior visual pathways are challenging to operate because of the crucial balance between extent of resection and sight preservation. Sodium Fluoresceine (SF) has already been reported in maximizing brain tumour resection but not when the optic-chiasmatic region is involved. The role of Visual Evoked Potentials (VEPs) in optic-chiasmatic tumours is still debated. The simultaneous use of both technique in this setting has not been reported so far. The aim of our work is to analyse the intraoperative combination of the use of SF and VEPs in the anterior visual pathway tumour surgery. METHODS: Clinical and Intra-operative data from six surgical procedures on four patients affected by optic-chiasmatic tumours with preoperative visual deficits were retrospectively analysed. RESULTS: In 5 procedures VEPs remained intraoperatively stable and no postoperative worsening of visual function was reported. In 1 case an intraoperative VEPs deterioration was predictive of a postoperative visual worsening. In all cases, tumour was fluorescent, and SF was intraoperatively helpful in guiding resection. The pattern of fluorescence was different according to the lesion histology. CONCLUSIONS: Based on our preliminary experience, the simultaneous combination of SF and VEPs in surgery of the optic pathway tumours seems helpful to maximize tumour resection and predict postoperative functional outcome. Since we presented a small series, larger studies are needed to confirm our data.

RESUMO

Simple summary: Low-grade serous ovarian cancer (LGSOC) represents an uncommon histotype of serous ovarian cancer (accounting for approximately 5% of all ovarian cancer) with a distinct behavior compared to its high-grade serous counterpart, characterized by a better prognosis and low response rate to chemotherapeutic agents. Similar to high-grade serous ovarian cancer, cytoreductive surgery is considered crucial for patient survival. This retrospective study aimed to analyze the outcomes of women affected by advanced stages (III-IV FIGO) of LGSOC from two high-volume oncological centers for ovarian neoplasm. In particular, we sought to evaluate the impact on survival outcomes of optimal cytoreductive surgery [i.e., residual disease (RD) <10 mm at the end of surgery]. The results of our work confirm the role of complete cytoreduction (i.e., no evidence of disease after surgery) in the survival of patients and even the positive prognostic role of a minimal RD (i.e., <10 mm), whenever complete cytoreduction cannot be achieved. Background: Low-grade serous ovarian cancer (LGSOC) is a rare entity with different behavior compared to high-grade serous (HGSOC). Because of its general low chemosensitivity, complete cytoreductive surgery with no residual disease is crucial in advanced stage LGSOC. We evaluated the impact of optimal cytoreduction on survival outcome both at first diagnosis and at recurrence. Methods: We retrospectively studied consecutive patients diagnosed with advanced LGSOCs who underwent cytoreductive surgery in two oncological centers from January 1994 to December 2018. Survival curves were estimated by the Kaplan-Meier method, and 95% confidence intervals (95% CI) were estimated using the Greenwood formula. Results: A total of 92 patients were included (median age was 47 years, IQR 35-64). The median overall survival (OS) was 142.3 months in patients with no residual disease (RD), 86.4 months for RD 1-10 mm and 35.2 months for RD >10 mm (p = 0.002). Progression-free survival (PFS) was inversely related to RD after primary cytoreductive surgery (RD = 0 vs RD = 1-10 mm vs RD >10 mm, p = 0.002). On multivariate analysis, RD 1-10 mm (HR = 2.30, 95% CI 1.30-4.06, p = 0.004), RD >10 mm (HR = 3.89, 95% CI 1.92-7.88, p = 0.0004), FIGO stage IV (p = 0.001), and neoadjuvant chemotherapy (NACT) (p = 0.010) were independent predictors of PFS. RD >10 mm (HR = 3.13, 95% CI 1.52-6.46, p = 0.004), FIGO stage IV (p <0.0001) and NACT (p = 0.030) were significantly associated with a lower OS. Conclusions: Optimal cytoreductive surgery improves survival outcomes in advanced stage LGSOC s . When complete debulking is impossible, a RD <10 mm confers better OS compared to an RD >10 mm in this setting of patients.

RESUMO

BACKGROUND: BRCA1 mutation carriers are recommended to undergo prophylactic risk-reducing salpingo-oophorectomy (RRSO) between the ages of 35 and 40 or when child bearing is complete, with a possible delay until age 40-45 for BRCA2 mutation carriers. STUDY QUESTION: Primary outcome was the rate of unsuspected cancer findings during RRSO in a region of northern Italy (Emilia Romagna) and secondary outcomes were details of RRSO: age at surgical intervention, the venue of the procedures in relation to the surgical/pathological quality and the rate/role of concomitant opportunistic hysterectomies. STUDY DESIGN: Multicentre data collection by invitation to report current RRSO practices. RESULTS: A total of 222 RRSOs (54.5 % BRCA1, 34.7 % BRCA2, 1.8 % BRCA1 and BRCA2 combined, 5.8 % BRCA-VUS and 3.2 % BRCA not better specified) were reported from 9 different centres, half in non-university hospitals and the remainder in university hospitals. Breast cancer survivors (56.3 %) underwent the RRSO at a younger age (47.8 vs 50.6 years, p =  0.02). The mean and median ages at surgical intervention (49.0 and 48.0, respectively) were similar for BRCA1 and BRCA2 mutation carriers, as was the temporal trend in age distribution, and proportions treated in university and non-university hospitals. A diagnosis of ovarian invasive cancer was reported in 3.5 % of subjects, all BRCA1 or BRCA-combined subjects, at a median and mean age of 57 years (range 42-68). Abnormal tubal findings, such as serous tubal intraepithelial lesions (STIL) (100 %), secretory cell outgrowth (SCOUT) (100 %) and STIC (71.4 %), were mainly reported by pathologists in university hospitals. Of the 222 procedures, 15 (6.7 %) included hysterectomies: in none of these cases was a primitive uterine endometrioid or serous cancer found. CONCLUSIONS: The results from this multicentre regional study should guide future preventive health policies for RRSO in BRCA mutation carriers.

RESUMO

BACKGROUND: Y-stenting is an effective but challenging approach for wide-neck aneurysms. PulseRider (PR) (Pulsar/Cerenovus) is a new device designed to provide scaffolding during coiling but has never been compared with other techniques. OBJECTIVE: To compare the immediate and 6-mo results of Y-stenting vs PR assisted coiling. METHODS: A total of 105 consecutive patients were retrospectively divided into 2 groups (73 Y-stenting and 32 PR). All underwent angiographic 6-mo follow-up. We evaluated if some anatomical features could influence treatment results. RESULTS: The groups were homogeneous. Immediate adequate occlusions as well as complication rates were similar in Y-stenting and PR group (94.5% vs 96.9% and 8.2% vs 6.2%, respectively). At 6 mo, adequate occlusion was 93.1% after Y-stenting and 84.3% after PR (P = .28), complete occlusion was significantly higher after Y-stenting: 90.3% vs 62.5% (P = .0017). Occlusion grade worsening occurred in 6.9% of Y-stenting and 18.7% of PR patients (P = .09).Neck size was associated with occlusion grade in both groups. Maximal aneurysm size was associated with occlusion grade in the PR group (P = .023) but not in the Y-stenting group (P = .06). After PR, 6-mo occlusion rate was higher in small (< 10 mm) than in large aneurysms (P = .0094); this was not observed after Y-stenting (P = .54).Location did not significantly affect the mid-term occlusion rate in both the groups. After PR, occlusion was more stable in basilar than anterior or middle cerebral artery aneurysms. CONCLUSION: Y-stenting and PR are both effective with similar immediate and mid-term results. However, treatment stability seems higher after Y-stenting. Aneurysm size seems to negatively affect PR results.

RESUMO

Anesthetic management of patients undergoing endovascular procedures for treating intracranial aneurysms or cerebrovascular malformations must consider a number of specific challenges, in addition to those associated with anesthesia for other specialties. In addition to maintenance of physiological stability, manipulation of systemic and cerebral hemodynamic parameters may be required to treat any sudden unexpected catastrophic neurological events. A multidisciplinary group including neuro- and pediatric anesthesiologists, interventional neuroradiologists, neurosurgeons, and a clinical methodologist contributed to this document. This consensus working group from 21 Italian institutions identified open questions regarding the best practices for management of anesthesia during endovascular neuroradiological procedures for intracranial aneurysms and cerebrovascular malformations, and addressed these by formulating practical consensus statements. At the first meeting in November 2015, nine key areas were identified regarding choice of anesthetic, patient monitoring, hemodynamic targets, postoperative care, and the management of neuromuscular blockade, anticoagulant and/or antiplatelet therapy, and special considerations for pediatric patients. Nine subgroups were established and a medical librarian performed literature searches in the Cochrane and MEDLINE/PubMed databases for each group. Groups drafted literature summaries and provisional responses in the form of candidate consensus statements based on evidence, when possible, and clinical experience, when this was lacking. Final wording was agreed at a meeting in April 2016 and where possible evidence was graded using United States Preventive Services Task Force criteria. Consensus (defined as >90% agreement) was based on evidence, clinical experience, clinician preference, feasibility in the Italian healthcare system, and cost/benefit considerations.

RESUMO

Ovarian cancer (OC) remains relatively rare, although it is among the top 4 causes of cancer death for women younger than 50. The aggressive nature of the disease and its often late diagnosis with peritoneal involvement have an impact on prognosis. The current scientific literature presents ambiguous or uncertain indications for management of peritoneal carcinosis (PC) from OC, both owing to the lack of sufficient scientific data and their heterogeneity or lack of consistency. Therefore, the Italian Society of Surgical Oncology (SICO), the Italian Society of Obstetrics and Gynaecology, the Italian Association of Hospital Obstetricians and Gynaecologists, and the Italian Association of Medical Oncology conducted a multidisciplinary consensus conference (CC) on management of advanced OC presenting with PC during the SICO annual meeting in Naples, Italy, on September 10-11, 2015. An expert committee developed questions on diagnosis and staging work-up, indications, and procedural aspects for peritonectomy, systemic chemotherapy, and hyperthermic intraperitoneal chemotherapy for PC from OC. These questions were provided to 6 invited speakers who answered with an evidence-based report. Each report was submitted to a jury panel, representative of Italian experts in the fields of surgical oncology, gynecology, and medical oncology. The jury panel revised the reports before and after the open discussion during the CC. This article is the final document containing the clinical evidence reports and statements, revised and approved by all the authors before submission.
