Ovarian cancer onset across different BRCA mutation types: a view to a more tailored approach for BRCA mutated patients.

OBJECTIVE: To evaluate the role of different specific types of germline breast cancer susceptibility BRCA mutations on the age of onset of high grade serous ovarian cancer. METHODS: This was a multicenter, international, retrospective cohort of 474 patients diagnosed with recurrent or newly diagnosed high grade serous ovarian cancer, with known germline mutations in BRCA1/2 genes, treated between January 2011 and December 2020 in three academic centers in Europe. Patients were classified into four groups related to the type of BRCA1/2 genes mutation: frameshift, missense, nonsense, and splicing. Data from patients with splicing mutations were removed from the analysis because of the small numbers. The other three groups were compared. RESULTS: Excluding the 29 patients with a splicing mutation, 474 patients were enrolled: 309 (65.2%) with frameshift mutations, 102 (21.5%) with nonsense mutations, and 63 (13.3%) with missense mutations. The BRCA1 gene was affected in 324 (68.4%) cases, while BRCA2 was involved in 150 (31.6%) women (p=0.06). We found a difference of more than 5 years in the age of onset of high grade serous ovarian cancer between BRCA1 and BRCA2 patients (mean 53.3 years vs 58.4 years; p=0.001), with a mean age of 55.1 years. Patients with nonsense germline mutations had the youngest age of onset, while women with frameshift mutations had the oldest age of onset of high grade serous ovarian cancer (mean 52.2 years vs mean 55.9 years), both in the BRCA1 and BRCA2 subgroups. There was no statistically significant difference in age of onset between early and advanced groups (mean 55.8 years vs 55.0 years; p=0.55). CONCLUSION: Different types of germline BRCA mutations could determine different ages for onset of high grade serous ovarian cancer. If confirmed in larger series, this finding might have a clinical impact, potentially leading to a more tailored approach for risk reducing surgery for the prevention of high grade serous ovarian cancer.

The prognostic role of systemic inflammatory markers in apparent early-stage ovarian cancer.

BACKGROUND: Few studies analyzed the prognostic role of systemic inflammatory markers in early-stage ovarian cancer. The primary endpoint of the present study was to assess the prognostic impact of baseline inflammatory markers in early-stage ovarian cancer. The secondary endpoints were to compare the disease-free survival (DFS) of inflammatory markers with standard risk factors and to correlate these with BRCA mutational status. METHODS: Retrospective, single-center, observational study. Patients with FIGO-stage I-II and IIIA1 epithelial ovarian cancer undergoing primary surgery between 10/2012 and 12/2019 were included. Inflammatory markers were evaluated on the results of the complete blood count and coagulation tests, performed before ovarian cancer surgery. The Receiver Operating Characteristic curve was used to determine the optimal cut-off value of different baseline inflammatory biomarkers for the DFS analysis. RESULTS: Three hundred fifty-nine patients were included in the study period. Baseline neutrophil-lymphocyte ratio (NLR) ≥ 3 and systemic immune inflammation index (SII, defined as platelet x neutrophil-lymphocyte ratio) ≥ 1000 were associated with worse 3 year DFS and baseline SII ≥ 1000 was associated with worse 3 year OS. BRCA-mutated patients with SII ≥ 1000 and with NLR ≥ 3 had significantly worse DFS compared to SII < 1000 and with NLR < 3. FIGO stage > I was the only independent risk factor for higher risk of recurrence. CONCLUSION: SII ≥ 1000 and NLR ≥ 3 were associated with worse 3 year DFS and SII ≥ 1000 was associated with worse 3 year OS. The subgroups of BRCA-mutated patients with higher inflammation markers (SII ≥ 1000 and NLR ≥ 3) were associated with worse DFS. These findings might be helpful to design personalized treatment and more intensive surveillance.

Fertility Sparing Treatments in Endometrial Cancer Patients: The Potential Role of the New Molecular Classification.

Endometrial cancer is the most frequent gynecological malignancy, and, although epidemiologically it mainly affects advanced age women, it can also affect young patients who want children and who have not yet completed their procreative project. Fertility sparing treatments are the subject of many studies and research in continuous evolution, and represent a light of hope for young cancer patients who find themselves having to face an oncological path before fulfilling their desire for motherhood. The advances in molecular biology and the more precise clinical and prognostic classification of endometrial cancer based on the 2013 The Cancer Genome Atlas classification allow for the selection of patients who can be submitted to fertility sparing treatments with increasing oncological safety. It would also be possible to predict the response to hormonal treatment by investigating the state of the genes of the mismatch repair.

Feasibility of tumor testing for BRCA status in high-grade serous ovarian cancer using fresh-frozen tissue based approach.

OBJECTIVE: For many years, BRCA mutational status has only been considered as a predictor of ovarian cancer susceptibility and as a prognostic factor. Nonetheless, in the era of precision medicine, it has also become a predictive biomarker of response to platinum-based-chemotherapy and, more recently, to PARP-inhibitors, also in the frontline setting. We assessed the feasibility of a fresh frozen tissue-based-BRCA-screening workflow in a tertiary referral center. METHODS: We consecutively enrolled a series of 456 newly diagnosed FIGO-Stage IIIC-IV, high grade serous-ovarian cancer patients. All patients receiving tumor-biopsy underwent tBRCA-testing. RESULTS: Clinically relevant tissue-BRCA (tBRCA) variants were observed in 145 women (31.8%), particularly we recognized 89 (61.4%) patients with BRCA1-pathogenetic variants (PVs) and 56 women (38.6%) with BRCA2-PVs. Among 292 tBRCA wild-type (wt) patients, 88 cases were germline BRCA tested (gBRCA) and 86 (97.8%) were confirmed as gBRCAwt, while 1 (1.1%) had gBRCA variant of uncertain significance and 1 had gBRCA mutation (1.1%). The concordance of tumor test versus germline BRCA test was 86.3% (209/242). Large genomic rearrangements (LGRs) were suspected in 13/292 tBRCAwt patients (4.5%) by using bioinformatic algorithm and multiplex ligation-dependent probe amplification (MLPA) was performed, with evidence of PVs in only 1 case. CONCLUSIONS: Fresh-frozen tissue-based BRCA screening workflow is feasible and reliable. It allows to enlarge the BRCA mutated population that might receive PARPi with the greatest benefit, without missing cascade testing for family members and therefore, maintaining its preventive role.

Spliceogenic analysis of BRCA1 c.439T>C (rs794727800) variant by High Resolution Melting Analysis.

Correct classification of genomic variants causing potentially aberrant splicing is of utmost importance for patient management, especially in clinically actionable genes such as BRCA1/2. In this article, we report molecular evaluation of the BRCA1 c.439T>C (rs794727800, p.Leu147=) variant based on RNA of a patient suffering with high-grade serous ovarian cancer syndrome, to add new evidence to the only in silico data available for this variant. High Resolution Melting Analysis (HRMA) was used for the first time to investigate the spliceogenicity of a BRCA1 variant. HRMA with Sanger sequencing provided evidence that the c.439C allele does not cause aberrant splicing of the BRCA1 exon 7. In addition, HRMA with Sanger highlighted a different expression of the naturally occurring BRCA1 r.442_444del (c.442_444delCAG, p.Gln148del, at DNA level) isoform between blood and tumor, in this patient. HRMA is an alternative molecular approach to analyze spliceogenic properties of the c.439T>C variant and potentially for all those BRCA1/2 variants affecting splicing sites. These new evidences allowed to classify definitively the c.439T>C variant as benign. Furthermore, the different BRCA1 r.442_444del expression opens the discussion to consider a wider classification criteria for the splicing variants, including molecular evaluation at tissue level, which is an aspect currently scarcely considered in BRCA1/2 variant classification recommendations.

Airway Closure during Surgical Pneumoperitoneum in Obese Patients.

BACKGROUND: Airway closure causes lack of communication between proximal airways and alveoli, making tidal inflation start only after a critical airway opening pressure is overcome. The authors conducted a matched cohort study to report the existence of this phenomenon among obese patients undergoing general anesthesia. METHODS: Within the procedures of a clinical trial during gynecological surgery, obese patients underwent respiratory/lung mechanics and lung volume assessment both before and after pneumoperitoneum, in the supine and Trendelenburg positions, respectively. Among patients included in this study, those exhibiting airway closure were compared to a control group of subjects enrolled in the same trial and matched in 1:1 ratio according to body mass index. RESULTS: Eleven of 50 patients (22%) showed airway closure after intubation, with a median (interquartile range) airway opening pressure of 9 cm H2O (6 to 12). With pneumoperitoneum, airway opening pressure increased up to 21 cm H2O (19 to 28) and end-expiratory lung volume remained unchanged (1,294 ml [1,154 to 1,363] vs. 1,160 ml [1,118 to 1,256], P = 0.155), because end-expiratory alveolar pressure increased consistently with airway opening pressure and counterbalanced pneumoperitoneum-induced increases in end-expiratory esophageal pressure (16 cm H2O [15 to 19] vs. 27 cm H2O [23 to 30], P = 0.005). Conversely, matched control subjects experienced a statistically significant greater reduction in end-expiratory lung volume due to pneumoperitoneum (1,113 ml [1,040 to 1,577] vs. 1,000 ml [821 to 1,061], P = 0.006). With airway closure, static/dynamic mechanics failed to measure actual lung/respiratory mechanics. When patients with airway closure underwent pressure-controlled ventilation, no tidal volume was inflated until inspiratory pressure overcame airway opening pressure. CONCLUSIONS: In obese patients, complete airway closure is frequent during anesthesia and is worsened by Trendelenburg pneumoperitoneum, which increases airway opening pressure and alveolar pressure: besides preventing alveolar derecruitment, this yields misinterpretation of respiratory mechanics and generates a pressure threshold to inflate the lung that can reach high values, spreading concerns on the safety of pressure-controlled modes in this setting.

The role of robotic aortic lymphadenectomy in gynecological cancer: surgical and oncological outcome in a single institution experience.

BACKGROUND AND OBJECTIVE: This study aims to investigate the surgical outcomes observed in robotic transperitoneal aortic lymphadenectomy (AL) in gynecological cancer patients. METHODS: Retrospective data were collected and analyzed on 71 patients undergoing robotic surgical procedures for gynecological cancers, including transperitoneal AL, between December 2014 and February 2018 at the Catholic University of the Sacred Heart, Rome, Italy. RESULTS: Median age of the sample population was 50 years (range, 26-76 years). The median operative time was 210 minutes (range, 75-480 minutes), the median estimated blood loss was 50 ml (range, 20-300 ml). The number of para-aortic nodes removed was 12 (range, 7-43). In the whole series, 13 patients (18.3%) had at least one metastatic node. Overall, 10 patients (14.1%) experienced any grade early postoperative complications. Three patients experienced more than one complication. Three intraoperative complications occurred with two cases of vascular injury. Conversion to laparotomy was necessary for one patient (1.4%). CONCLUSIONS: The present study shows the safety and adequacy of robotic transperitoneal AL as surgical staging step for gynecological cancers in terms of perioperative and postoperative outcomes.

BRCA Mutation Status to Personalize Management of Recurrent Ovarian Cancer: A Multicenter Study.

OBJECTIVE: The aim of this study was to assess the correlation between BRCA mutation status and disease presentation, treatment strategy, and survival in a multicenter series of recurrent high-grade serous ovarian cancer (HGSOC) women. METHODS: A consecutive series of recurrent HGSOC patients with partially or fully platinum-sensitive disease admitted to the Gynecologic Oncology Units of the Catholic University of the Sacred Heart and Sapienza University of Rome. Main eligibility criteria were known BRCA 1/2 germline mutation status and a minimum follow-up period from recurrence of at least 6 months. RESULTS: Overall, 126 patients met the eligibility criteria, of whom 76 (60%) were BRCA wild-type (BRCAwt) and 50 (40%) were BRCA 1/2 germline mutation carriers (BRCAmut). Among the latter, 37 (74%) patients presented with BRCA1 mutation, and 13 (26%) presented with BRCA2. No differences were found regarding patterns of disease presentation between BRCAwt and BRCAmut women. BRCAmut patients had the best post-recurrence survival (PRS) regardless of having received secondary cytoreductive surgery (SCS) or not, with a 5-year PRS of 73% in non-resected women versus 78% in resected women (p = 0.558). Conversely, BRCAwt patients who underwent complete SCS had a significantly longer PRS compared with BRCAwt patients who did not receive surgery (5-year PRS of 54% vs. 42%; p = 0.048). CONCLUSIONS: Recurrent ovarian cancer BRCAmut patients have the best prognosis regardless of SCS, whereas PRS in BRCAwt women can improve when complete SCS is performed. The identification and incorporation of predictive biomarkers such as BRCA status to tailor the medical and surgical approach is paramount to the success of recurrent HGSOC treatments.

Robotic Splenectomy for Isolated Splenic Recurrence of Endometrial Adenocarcinoma.

STUDY OBJECTIVE: To demonstrate management of a rare case of an isolated intraparenchymal splenic metastasis of endometrial cancer with robotic-assisted surgery. DESIGN: Case report (Canadian Task Force Classification III). SETTING: A 55-year-old patient with a history of endometrial cancer was found to have a splenic lesion on a follow-up examination. She underwent surgical staging, involving total hysterectomy, bilateral salpingo-oopherectomy, pelvic lymphadenectomy, and peritoneal washing, in 2014, and the final pathological findings showed an endometrioid endometrial adenocarcinoma, International Federation of Gynecology and Obstetrics stage IB G2. Multidisciplinary counseling was provided, and the patient opted for strict medical surveillance. At 20 months after the primary treatment, the patient experienced a vaginal cuff recurrence and refused radiation therapy. She instead underwent robotic surgery, followed by 6 cycles of carboplatin 6 AUC and paclitaxel 175 mg/m2. Seventeen months later, a positron emission tomography/computed tomography scan revealed a 3-cm intraparenchymal lesion of the spleen, and robotic splenectomy was scheduled. The Institutional Review Board approved this study. INTERVENTION: The operative time was 90 minutes, and blood loss was <50 mL. The operation was performed successfully, with no intraoperative and postoperative complications. Histopathological analysis showed a 3-cm intraparenchymal splenic lesion. The patient was discharged on day +2, and 46 days later started adjuvant chemotherapy based on carboplatin 6 AUC and doxorubicin (Caelyx) 30 mg/m2. At a 2-month follow-up, the patient was disease-free and in good general condition. CONCLUSION: This case demonstrates the successful robotic management of recurrent endometrial cancer.

Robotic Surgery in Elderly and Very Elderly Gynecologic Cancer Patients.

STUDY OBJECTIVE: To investigate the feasibility, safety, and short-term outcomes of robotic surgery (RS) for gynecologic oncologic indications (cervical, endometrial, and ovarian cancer) in elderly patients, especially women age 65 to 74 years (elderly group [EG]) compared with women age ≥75 years (very elderly group [VEG]). DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Catholic University of the Sacred Heart, Rome, Italy. PATIENTS: Between May 2013 and April 2017, 204 elderly and very elderly patients underwent RS procedures for gynecologic malignancies. RESULTS: The median age was 71 years (range, 65-74 years) in the EG and 77 years (range, 75-87 years) in the VEG. The incidence of cardiovascular disease was higher in the VEG (p = .038). The EG and VEG were comparable in terms of operative time, blood loss, and need for blood transfusion. Almost all (98.5%) of the patients underwent total/radical hysterectomy, 109 patients (55.6% of the EG vs 48.3% of the VEG) underwent pelvic lymphadenectomy, and 19 patients (10.5% of the EG vs 6.7% of the VEG) underwent aortic lymphadenectomy. A total of 7 (3.4%) conversions to open surgery were registered. Only 3 patients required postoperative intensive care unit admission. The median length of hospital stay was 2 days in each group. A total of 11 patients (5.6%) had early postoperative complications. Four patients (2.8%) in the EG and 2 patients (3.3%) in the VEG experienced grade ≥2 complications. At the time of analysis, median follow-up was 18 months (range, 6-55 months). Eleven patients (5.6%) experienced disease relapse, 2 (1%) died of disease, and 3 (1.5%) died of cardiovascular disease. CONCLUSIONS: This study demonstrates the feasibility, safety, and good short-term outcomes of RS in elderly and very elderly gynecologic cancer patients. No patient can be considered too old for a minimally invasive robotic approach, but a multidisciplinary approach is the best management pathway; efforts to reduce associated morbidity are essential.

Secondary cytoreduction in ovarian cancer: who really benefits?

PURPOSE: To identify women affected by recurrent ovarian cancer who benefit from secondary cytoreductive surgery (SCS), analyse their clinical and biological features and investigate the role of minimally invasive surgery (MIS) and hyperthermic intraperitoneal-based chemotherapy (HIPEC) in this subset of patients. METHODS: This narrative review examines the data available from the updated literature. An electronic literature search was conducted in PubMed Medline databases for articles published from 1990 to 2018. RESULTS: Retrospective studies and preliminary data from the AGO-Desktop III trial show that cytoreductive surgery is associated with improved post-relapse survival in patients with platinum-sensitive relapse, compared to chemotherapy alone. This benefit is more evident in patients treated with complete or optimal primary debulking surgery at referral centres, who did not receive bevacizumab in first-line chemotherapy, and who present a localized pattern of disease. MIS has been proven to be a favourable approach to achieve a complete secondary debulking, reducing peri- and postoperative comorbidities. The application of HIPEC to SCS is associated with an improvement in oncological outcomes by preliminary results. CONCLUSIONS: While waiting for the final results of the ongoing randomized controlled trials, SCS seems feasible and safe in selected patients with recurrent ovarian cancer. Recently, more attention has been focused on the biological features of ovarian tumours, such as BRCA status. Further studies and molecular research should be conducted to identify individualized and targeted therapies in the treatment of ovarian cancer recurrences.

Pre-cervical ripening and hygroscopic cervical dilators in pre-labor induction.

INTRODUCTION: Induction of labor (IOL) is becoming a universal topic in Obstetrics, when the risk of continuing a pregnancy outweighs the benefits. Preinduction is a more recent tool to prepare the cervix when the BISHOP-score is low. About one-third of IOL cases require cervical ripening, which is the physical softening, thinning, and dilation of the cervix in preparation for labor and birth. We report a single center experience regarding the use of hygroscopic dilators in the pre-labor phase to obtain cervical ripening before labor induction. MATERIALS & METHODS: We conducted a retrospective observational study comparing patient records from the Gynecology and Obstetrics Unit in "Santo Stefano" Hospital in Prato, Tuscany. The inclusion criteria for participants were women who had undergone pre-labor induction because of a BISHOP-score < 3. The gestational age of all the pregnant women was at term (> 37 weeks). RESULTS: From January 2022 to April 2022, a total of 581 women delivered at term of gestational age at the Gynecology and Obstetrics Unit in "Santo Stefano" Hospital. Cervical ripening was necessary for 82 women with a Bishop score < 3 and hygroscopic cervical dilators were used in 35/82 (42.7%) patients. All patients showed a change in Bishop-score upon removal of the dilators. All 35 patients (100%) reported an increase in terms of consistency and dilation of the cervix but not in terms of length. None of the patients reported discomfort during the 24 h that they kept the hygroscopic dilators in place. No patients reported uterine tachysystole on cardiotocographic tracing, vaginal bleeding, rupture of membranes or cervical tears. CONCLUSIONS: Our results are in line with those in the literature, demonstrating the validity of hygroscopic dilators in cervical maturation of pregnancies at term and their efficacy was again highlighted in terms of both maternal and fetal safety and patient satisfaction.

Lung-protective ventilation during Trendelenburg pneumoperitoneum surgery: A randomized clinical trial.

Study objective To assess the effects of a protective ventilation strategy during Trendelenburg pneumoperitoneum surgery on postoperative oxygenation. DESIGNS: Parallel-group, randomized trial. SETTING: Operating room of a university hospital, Italy. PATIENTS: Morbidly obese patients undergoing Trendelenburg pneumoperitoneum gynaecological surgery. INTERVENTIONS: Participants were randomized to standard (SV: tidal volume = 10 ml/kg of predicted body weight, PEEP = 5 cmH2O) or protective (PV: tidal volume = 6 ml/kg of predicted body weight, PEEP = 10 cmH2O, recruitment maneuvers) ventilation during anesthesia. MEASUREMENTS: Primary outcome was PaO2/FiO2 one hour after extubation. Secondary outcomes included day-1 PaO2/FiO2, day-2 respiratory function and intraoperative respiratory/lung mechanics, assessed through esophageal manometry, end-expiratory lung volume (EELV) measurement and pressure-volume curves. MAIN RESULTS: Sixty patients were analyzed (31 in SV group, 29 in PV group). Median [IqR] tidal volume was 350 ml [300-360] in PV group and 525 [500-575] in SV group. Median PaO2/FiO2 one hour after extubation was 280 mmHg [246-364] in PV group vs. 298 [250-343] in SV group (p = 0.64). Day-1 PaO2/FiO2, day-2 forced vital capacity, FEV-1 and Tiffenau Index were not different between groups (all p > 0.10). Intraoperatively, 59% of patients showed complete airway closure during pneumoperitoneum, without difference between groups: median airway opening pressure was 17 cmH2O. In PV group, airway and transpulmonary driving pressure were lower (12 ± 5 cmH2O vs. 17 ± 7, p < 0.001; 9 ± 4 vs. 13 ± 7, p < 0.001), PaCO2 and respiratory rate were higher (48 ± 8 mmHg vs. 42 ± 12, p < 0.001; 23 ± 5 breaths/min vs. 16 ± 4, p < 0.001). Intraoperative EELV was similar between PV and SV group (1193 ± 258 ml vs. 1207 ± 368, p = 0.80); ratio of tidal volume to EELV was lower in PV group (0.45 ± 0.12 vs. 0.32 ± 0.09, p < 0.001). CONCLUSIONS: In obese patients undergoing Trendelenburg pneumoperitoneum surgery, PV did not improve postoperative oxygenation nor day-2 respiratory function. PV was associated with intraoperative respiratory mechanics indicating less injurious ventilation. The high prevalence of complete airway closure may have affected study results. TRIAL REGISTRATION: Prospectively registered on http://clinicaltrials.govNCT03157479 on May 17th, 2017.

Can the Modified Frailty Index (mFI) Predict Intraoperative and Postoperative Complications in Older Women with Endometrial Cancer Undergoing Laparoscopic or Robotic Surgery? A Multicenter Observational Study.

BACKGROUND: This study aims to evaluate the strength of the association between frailty and intraoperative/postoperative complications in patients undergoing minimally invasive surgery (MIS) for endometrial cancer. METHODS: In this retrospective observational multicenter cohort study, frailty was defined beforehand by a modified frailty index (mFI) score of ≥3. Multiple logistic regressions were performed to investigate possible preoperative predictors-including frailty, age, and body mass index-of intraoperative and early (within 30 days from surgery) or delayed (beyond 30 days from surgery) postoperative complications. RESULTS: The study involved 577 women, of whom 6.9% (n = 40) were frail with an mFI ≥ 3, while 93.1% (n = 537) were non-frail with an mFI of 0-2. Frail women had a significantly higher rate of intraoperative complications (7.5% vs. 1.7%, p = 0.01), with odds 4.54 times greater (95% CI: 1.18-17.60, p = 0.028). There were no differences in the rate of early postoperative complications (15% vs. 6.9%, p = 0.06) and delayed postoperative complications (2.5% vs. 3.9%, p = 0.65) for frail versus non-frail patients. The odds of early postoperative complications increased by 0.7% (95% CI: 1.00-1.15) for every one-unit increase in age (p = 0.032). CONCLUSIONS: Frailty was associated with a significantly higher risk of intraoperative complications in older women undergoing MIS for endometrial cancer. Likewise, increasing age was an independent predictor of early postoperative complications. Our findings support the practice of assessing frailty before surgery to optimize perioperative management in this patient population.

Hyperthermic intraperitoneal chemotherapy (HIPEC) after primary debulking surgery in advanced epithelial ovarian cancer: Is BRCA mutational status making the difference?

INTRODUCTION: The role of a molecular pattern predictive of hyperthermic intraperitoneal chemotherapy (HIPEC) efficacy in advanced ovarian cancer (AOC) patients has been poorly investigated. We aimed to assess the effect of HIPEC after primary debulking surgery (PDS) in AOC according to patient's Breast Cancer Gene (BRCA) mutational status. METHODS: This is a retrospective, single center, case-control study. Data on AOC patients receiving HIPEC at the end of PDS as previously enrolled in a phase II monocentric trial (HIPEC group), were retrieved and matched for clinical and surgical characteristics with a group of cases who underwent PDS without receiving HIPEC between 01/2010 and 01/2015 (No HIPEC group). Patients with International Federation of Gynecology and Obstetrics (FIGO) stage ≥IIIB disease, aged between 18 and 70 years, with a laparoscopic Predictive Index value (PIV) ≤8 and residual disease ≤2.5 mm were included. RESULTS: 70 patients were included. With the except of age (p = 0.012), the populations were balanced for the main characteristics. At a median follow-up of 48 months, no differences in Progression Free Survival (PFS) (p = 0.968) and Overall Survival (OS) (p = 0.789) were recorded. Survival analysis according to HIPEC administration and BRCA mutational status showed an improved PFS (p = 0.011) and OS (p = 0.003) in BRCA mutated compared to wild-type patients when HIPEC was not administered, whilst they were superimposable in case of HIPEC administration (p = 0.857 vs p = 0.372; respectively). No differences in terms of neither intra-operative (p = 1.0) nor early post-operative complications (p = 0.920) were detected. CONCLUSIONS: Our results show that HIPEC in AOC may be a promising treatment in BRCA wild-type patients, as it seems to balance their decreased chemosensitivity compared to mutation carriers.

Contrast Agents during Pregnancy: Pros and Cons When Really Needed.

Many clinical conditions require radiological diagnostic exams based on the emission of different kinds of energy and the use of contrast agents, such as computerized tomography (CT), positron emission tomography (PET), magnetic resonance (MR), ultrasound (US), and X-ray imaging. Pregnant patients who should be submitted for diagnostic examinations with contrast agents represent a group of patients with whom it is necessary to consider both maternal and fetal effects. Radiological examinations use different types of contrast media, the most used and studied are represented by iodinate contrast agents, gadolinium, fluorodeoxyglucose, gastrographin, bariumsulfate, and nanobubbles used in contrast-enhanced ultrasound (CEUS). The present paper reports the available data about each contrast agent and its effect related to the mother and fetus. This review aims to clarify the clinical practices to follow in cases where a radiodiagnostic examination with a contrast medium is indicated to be performed on a pregnant patient.

Update on the secondary cytoreduction in platinum-sensitive recurrent ovarian cancer: a narrative review.

The ovarian cancer recurrence occurs in 75% of patients with advanced FIGO stage, and its treatment is a challenge for the oncologist in gynecology. The standard treatment of recurrent ovarian cancer (ROC) usually includes intravenous chemotherapy according to platinum sensitivity. Furthermore, maintenance treatment with target therapies [e.g., anti-angiogenic drug or PARP inhibitors (PARPi)], should be provided if not precedently administrated. In this scenario, secondary cytoreductive surgery (SCS) remains a practical but controversial option for platinum-sensitive ROC (PSROC). So far, several retrospective series and a Cochrane meta-analysis had concluded that SCS could determine better survival outcomes in ROC with favorable prognostic characteristics, such as the presence of a single anatomical site of recurrence, or when patients are accurately selected for surgery based on complete resection's predictive models. Recently, three randomized clinical trials (RCTs) investigated the role of SCS in PSROC patients selected with different criteria. All the three RCTs showed a significant statistical advantage in progression-free survival (PFS) in the SCS group, with an even more significant difference in patients with complete cytoreduction (about 7-month PFS increased). Data on overall survival (OS) are different in the two completed trials. The GOG213 study has documented a longer OS of PSROC patients who received chemotherapy alone compared to surgery plus chemotherapy. Contrarily, the DESKTOP III trial showed 7.7 months of increased OS in the surgery group vs. chemotherapy alone, with a more difference in the complete tumor cytoreduction (CTC) group (12 months). These RCTs thereby suggest that undergoing complete cytoreduction may not be the only key and that the disease biology may also matter. Few recent retrospective series investigated the role of SCS according to BRCA mutation status and the effect of SCS in patients receiving emerging PARPi. A consequence of the developments in SCS and knowledge of different molecular pathways influencing the recurrent disease is that the future research objective should be to individualize and personalize the surgical approach.

NLR and BRCA mutational status in patients with high grade serous advanced ovarian cancer.

Laboratory-markers of the systemic inflammatory-response, such as neutrophil/lymphocyte-ratio (NLR) have been studied as prognostic factors in several tumors but in OC-patients their role is still controversial and no data about the possible correlation with the BRCA-status has been ever reported. We consecutively enrolled a series of 397 newly diagnosed high-grade serous-advanced OC-patients. All patients were tested for BRCA-mutational-status and blood-parameters have been collected 48 h before staging-surgery. A significant correlation of NLR with disease distribution (p < 0.005) was found and patients with NLR < 4 underwent primary-debulking-surgery more frequently (p-value 0.001), with a lower surgical-complexity-score (p-value 0.002). Regarding survival-data, patients with NLR < 4 had a significant 7-month increase in mPFS (26 vs 19 months, p = 0.009); focusing on the BRCA-status, among both BRCA-mutated and BRCA-wild type patients, those with lower NLR had a significantly prolonged mPFS compared to patients with NLR > 4 (BRCA-mutated: 35 vs 23 months, p = 0.03; BRCA-wt: 19 vs 16 months, p = 0.05). At multivariate-analysis, independent factors of prolonged PFS were BRCA mutational status, having received complete cytoreduction and NLR < 4. Also, the strongest predictors of longer OS were BRCA-mutational status, having received complete cytoreductive surgery, NLR < 4 and age. NLR is confirmed to be a prognostic marker in OC-patients and it seems unrelated with BRCA-mutational status.
