Adverse effects of sodium-glucose cotransporter-2 inhibitors in patients with heart failure: a systematic review and meta-analysis.

Sodium-glucose cotransoporter-2 inhibitors (SGLT-2Is) improve prognosis in heart failure (HF) patients both with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). However, these drugs can have some side effects. To estimate the relative risk of side effects in HF patients treated with SGLT-2Is irrespective from left ventricular EF and setting (chronic and non-chronic HF). Five randomized controlled trials (RCTs) enrolling patients with HFrEF, 4 RCTs enrolling non-chronic HF, and 3 RCTs enrolling HFpEF were included. Among side effects, urinary infection, genital infection, acute kidney injury, diabetic ketoacidosis, hypoglycemia, hyperkalemia, hypokalemia, bone fractures, and amputations were considered in the analysis. Overall, 24,055 patients were included in the analysis: 9020 (38%) patients with HFrEF, 12,562 (52%) with HFpEF, and 2473 (10%) with non-chronic HF. There were no differences between SGLT-2Is and placebo in the risk to develop diabetic ketoacidosis, hypoglycemia, hyperkalemia, hypokalemia, bone fractures, and amputations. HFrEF patients treated with SGLT-2Is had a significant reduction of acute kidney injury (RR = 0.54 (95% CI 0.33-0.87), p = 0.011), whereas no differences have been reported in the HFpEF group (RR = 0.94 (95% CI 0.83-1.07), p = 0.348) and non-chronic HF setting (RR = 0.79 (95% CI 0.55-1.15), p = 0.214). A higher risk to develop genital infection (overall 2.57 (95% CI 1.82-3.63), p < 0.001) was found among patients treated with SGLT-2Is irrespective from EF (HFrEF: RR = 1.96 (95% CI 1.17-3.29), p = 0.011; HFpEF: RR = 3.04 (95% CI 1.88-4.90), p < 0.001). The risk to develop urinary infections was increased among SGLT-2I users in the overall population (RR = 1.13 (95% CI 1.00-1.28), p = 0.046) and in the HFpEF setting (RR = 1.19 (95% CI 1.02-1.38), p = 0.029), whereas no differences have been reported in HFrEF (RR = 1.05 (95% CI 0.81-1.36), p = 0.725) and in non-chronic HF setting (RR = 1.04 (95% CI 0.75-1.46), p = 0.806). SGLT-2Is increase the risk of urinary and genital infections in HF patients. In HFpEF patients, the treatment increases the risk of urinary infections compared to placebo, whereas SGLT-2Is reduce the risk of acute kidney disease in patients with HFrEF.

Sacubitril/valsartan and arrhythmic burden in patients with heart failure and reduced ejection fraction: a systematic review and meta-analysis.

The aim of this study was to assess whether angiotensin receptor/neprilysin inhibitor (ARNI) decreases ventricular arrhythmic burden compared to angiotensin-converting enzyme inhibitors or angiotensin receptor antagonist (ACE-I/ARB) treatment in chronic heart failure with reduced ejection fraction (HFrEF) patients. Further, we assessed if ARNI influenced the percentage of biventricular pacing. A systematic review of studies (both RCTs and observational studies) including HFrEF patients and those receiving ARNI after ACE-I/ARB treatment was conducted using Medline and Embase up to February 2023. Initial search found 617 articles. After duplicate removal and text check, 1 RCT and 3 non-RCTs with a total of 8837 patients were included in the final analysis. ARNI was associated with a significative reduction of ventricular arrhythmias both in RCT (RR 0.78 (95% CI 0.63-0.96); p = 0.02) and observational studies (RR 0.62; 95% CI 0.53-0.72; p < 0.001). Furthermore, in non-RCTs, ARNI also reduced sustained (RR 0.36 (95% CI 0.2-0.63); p < 0.001), non-sustained VT (RR 0.67 (95% CI 0.57-0.80; p = 0.007), ICD shock (RR 0.24 (95% CI 0.12-0.48; p < 0.001), and increased biventricular pacing (2.96% (95% CI 2.25-3.67), p < 0.001). In patients with chronic HFrEF, switching from ACE-I/ARB to ARNI treatment was associated with a consistent reduction of ventricular arrhythmic burden. This association could be related to a direct pharmacological effect of ARNI on cardiac remodeling.Trial registration: CRD42021257977.

Is the sarcomatous component (homologous vs heterologous) the prognostic "driving force" in early-stage uterine carcinosarcomas? A retrospective multicenter study.

PURPOSE: Uterine carcinosarcomas (UCSs) are aggressive biphasic malignancies, with a carcinomatous/epithelial component and a sarcomatous/mesenchymal counterpart. The aim of this study was to evaluate the impact of the sarcomatous component (homologous vs heterologous) on the overall survival (OS) and progression-free survival (PFS). METHODS: This is a multicenter observational retrospective study conducted in patients with stage I and II UCSs. RESULTS: Ninety-five women with histological diagnosis of early-stage UCSs were retrieved: 60 (63.2%) had tumors with homologous sarcomatous components, and 35 (36.8%) with heterologous. At univariate analysis, a stromal invasion ≥ 50%, the presence of clear cell, serous or undifferentiated carcinomatous component, the heterologous sarcomatous component and FIGO stage IB and II were shown to be variables with a statistically significant negative impact on PFS. Similarly, a depth of invasion ≥ 50%, the heterologous sarcomatous component and FIGO stage IB and II were statistically negative prognostic factors also concerning OS. At multivariate analysis, only the heterologous sarcomatous component was confirmed to be a statistically significant negative prognostic factor both on PFS (HR 2.362, 95% CI 1.207-4.623, p value = 0.012) and on OS (HR 1.950, 95% CI 1.032-3.684, p = 0.040). CONCLUSION: Carcinomatous and sarcomatous components both played a role in tumor progression and patients' survival. However, only the sarcomatous component retained a statistical significance at the multivariable model suggesting its preeminent prognostic role in early-stage UCSs.

The role of brachytherapy (interventional radiotherapy) for primary and/or recurrent vulvar cancer: a Gemelli Vul. Can multidisciplinary team systematic review

Objective The aim of our systematic review was to assess the role of interventional radiotherapy (IRT, brachytherapy) in the management of primary and/or recurrent vulvar carcinoma. Evidence acquisition A systematic research using PubMed, Scopus and Cochrane library was performed. ClinicalTrials.gov was searched for ongoing or recently completed trials, and PROSPERO was searched for ongoing or recently completed systematic reviews. Only full-text English-language articles related to IRT for treatment of primary or recurrent VC were identified and reviewed. Conference paper, survey, letter, editorial, book chapter and review were excluded. Time restriction (1990–2018) as concerns the years of the publication was considered. Evidence synthesis Primary disease: the median 5-year LC was 43.5% (range 19–68%); the median 5-year DFS was 44.5% (range 44–81%); the median 5-year OS was 50.5% (range 27–85%). Recurrent disease: the median 5-year DFS was 64% (range 56–72%) and the median 5-year OS was 45% (range 33%-57%). Acute ≥ grade 2 toxicity was reported in three patients (1.6%). The severe late toxicity rates (grade 3–4) ranged from 0% to 14.3% (median 7.7%). Conclusion IRT as part of primary treatment for primary and/or recurrent vulvar cancer is associated with promising clinical outcomes (AU)

Pattern of recurrence in patients with endometrial cancer: A retrospective study.

INTRODUCTION: Endometrial cancer (EC) known prognostic factors are not sufficient to predict either outcome or recurrence rate/site: to investigate EC recurrence patterns according to ESMO-ESGO-ESTRO risk classes, could be beneficial for a more tailored adjuvant treatment and follow-up schedule. METHODS: 758 women diagnosed with EC, and a 5-years follow-up, were enrolled: they were divided into the ESMO-ESGO-ESTRO risk classes (low LR, intermediate IR, intermediate-high I-HR, and highrisk HR) and surgically treated as recommended, followed by adjuvants therapies when appropriate. RESULTS: Higher recurrence rate (RR) was significantly detected (p < 0,001) in the HR group (40,3%) compared to LR (9,6%), IR (16,7%) and I-HR (17,1%). Recurrences were detected more frequently at distant sites (64%) compared to pelvic (25,3%) and lymph nodes (10,7%) recurrences (p < 0,0001): only in LR group, no differences were detected between local and distant recurrences. 5-Year distant-free (LR 99%, IR 94%,I-HR 86%, HR 88%) and local-free survivals (LR 99%, IR 100%,I-HR 98%, HR 95%) significantly differ between groups (p < 0,0001 and p = 0,003, respectively). Adjuvant therapy modifies RRs only in LR group (p = 0,01). CONCLUSION: To identify biological factors to stratify patients at higher risk of relapse is needed. Distant site relapse could be the main reason of endometrial cancer failure follow-up, independently or in addition to their risk class prognosis.

Fertility preservation in chemo-radiotherapy for rectal cancer: A combined approach.

INTRODUCTION: Colorectal cancer is a very common form of cancer worldwide, affecting an increasing number of young women. Standard treatment for locally advanced rectal cancer (LARC) can pose a threat to fertility in these patients. CASE PRESENTATION: We present the case of a young woman affected by LARC who expressed a desire for child-bearing. The treatment she was proposed, according to guidelines, was neoadjuvant chemo-radiotherapy (CRT) followed by delayed surgery, carrying with it a high risk for amenorrhea. Counselling was performed before the initiation of treatment, with the aim of preserving fertility by the proposal of GnRH agonist administration, ovarian transposition and ovarian tissue cryopreservation, which the patient accepted. Treatment was then successfully completed. The patient presented regular menstrual period from before the surgery. DISCUSSION: Ovarian tissue is very sensitive to radiations. Transposition of the organ can prevent ovarian insufficiency by placing it outside the radiation field, while ovarian tissue cryopreservation and orthotopic transplantation offers the possibility to restore fertility in the case of organ failure. We performed both of the techniques. GnRH analogs administration allowed to diminish the risk of ovarian cytotoxicity. Radiation treatment plan was optimized in order to minimize the dose to organs at risk (ovary and vagina in particular); position of the uterus, which is quite radiosensitive too, was monitored with daily cone-beam CT (CBCT). CONCLUSION: The strategy proposed seemed safe and effective, resulting in radical treatment and persistence of regular menstrual period. Further studies are needed.

Robotic Single-Port Platform in General, Urologic, and Gynecologic Surgeries: A Systematic Review of the Literature and Meta-analysis.

BACKGROUND: Robotic platforms have recently acquired progressive importance in different surgical fields, such as urology, gynecology, and general surgery. Through the years, new surgical robots have become available as single-port robotic platform. The study is aimed to value the single-port robotic platform characteristics in different surgical specialties. METHODS: The terms "LESS" OR "single port" OR "single site" AND "robot" OR "robotic" were systematically used to search the PubMed and Scopus databases. A total of 57 studies were considered eligible for the present review. The articles included were divided according to the surgical field in which the study was conducted: General surgery (29 articles), Gynecology (18 articles), Urology (10 articles). RESULTS: Most part of the articles showed the feasibility of robotic single-port surgical procedures and described advantages in terms of cosmetic, hospital stay, and in some series even cost reduction. A meta-analysis was conducted, showing a significant increment of complications using RSP if compared with SLPS and a trend (P = 0.008) when RSP was compared with LESS. The comparison of different techniques in terms of conversion to laparotomy did not show any significant difference. CONCLUSION: Robotic single port potentially furnishes an important surgical and post-operatory improvement; however, some limits still prolong the surgical time and complication rate.

The INTERNATIONAL MISSION study: minimally invasive surgery in ovarian neoplasms after neoadjuvant chemotherapy.

OBJECTIVES: The aim of this retrospective multicenter study was to investigate the extent, feasibility, and outcomes of minimally invasive surgery at the time of interval debulking surgery in different gynecological cancer centers. METHODS/MATERIALS: In December 2016, 20 gynecological cancer centers were contacted by e-mail, to participate in the INTERNATIONAL MISSION study. Seven centers confirmed and five were included, with a total of 127 patients diagnosed with advanced epithelial ovarian cancer after neoadjuvant chemotherapy and minimally invasive interval surgery. Only women with a minimum follow-up time of 6 months from interval surgery or any cancer-related event before 6 months were included in the survival analysis. Baseline characteristics, chemotherapy, and operative data were evaluated. Survival analysis was evaluated using the Kaplan-Meier method. RESULTS : All patients had optimal cytoreduction at the time of interval surgery: among them, 122 (96.1%) patients had no residual tumor. Median operative time was 225 min (range 60 - 600) and median estimated blood loss was 100 mL (range 70 - 1320). Median time to discharge was 2 days (1-33) and estimated median time to start chemotherapy was 20 days (range 15 - 60). Six (4.7%) patients experienced intraoperative complications, with one patient experiencing two serious complications (bowel and bladder injury at the same time). There were six (4.7%) patients with postoperative short-term complications: among them, three patients had severe complications. The conversion rate to laparotomy was 3.9 %. Median follow-up time was 37 months (range 7 - 86): 74 of 127 patients recurred (58.3%) and 31 (24.4%) patients died from disease. Median progression-free survival was 23 months and survival at 5 years was 52 % (95% CI: 35 to 67). CONCLUSIONS: Minimally invasive surgery may be considered for the management of patients with advanced ovarian cancer who have undergone neoadjuvant chemotherapy, when surgery is limited to low-complexity standard cytoreductive procedures.

MetaShot: an accurate workflow for taxon classification of host-associated microbiome from shotgun metagenomic data.

SUMMARY: Shotgun metagenomics by high-throughput sequencing may allow deep and accurate characterization of host-associated total microbiomes, including bacteria, viruses, protists and fungi. However, the analysis of such sequencing data is still extremely challenging in terms of both overall accuracy and computational efficiency, and current methodologies show substantial variability in misclassification rate and resolution at lower taxonomic ranks or are limited to specific life domains (e.g. only bacteria). We present here MetaShot, a workflow for assessing the total microbiome composition from host-associated shotgun sequence data, and show its overall optimal accuracy performance by analyzing both simulated and real datasets.

Robotic single site staging in endometrial cancer: A multi-institution study.

OBJECTIVE: To evaluate the feasibility and the safety of robotic single site hysterectomy (RSSH) plus or less pelvic lymphadenectomy in FIGO stage I-II endometrial cancer. MATERIALS AND METHODS: We prospectively collected patient demographics, operative times, complications, pathologic results, and length of stay on all patients who underwent RSSH plus or less pelvic lymphadenectomy for clinical FIGO stage I or occult stage II endometrial carcinoma. RESULTS: From January 2012 to February 2015, 125 patients were included in our study. The median age of the patients was 59 years (range, 35-84 years) and the median body mass index was 27 kg/m(2) (range, 19-52 kg/m(2)). One patient was converted to vaginal surgery due to problems of hypercapnia. The median docking time, console time, and total operative time was 11 min (range, 4-40 min), 80 min (range, 20-240 min) and 122 min (range, 35-282 min), respectively. The median blood loss was 50 ml (range, 10-250 ml). No laparoscopic/laparotomic conversion was registered. Twenty one patients underwent pelvic lymphadenectomy (16.8%) and the median pelvic lymph nodes was 13 (range, 3-32). The median time to discharge was 2 days (range, 1-3 days). No intra-operative complications occurred, while we observed 10 (8%) early post-operative complications. CONCLUSION: RSSH plus or less pelvic lymphadenectomy is technically feasible, safe and reproducible and could be the treatment of choice for patients affected by FIGO stage I-II endometrial cancer. However, randomized controlled trials are needed to confirm these results.

Radical hysterectomy after chemoradiation in FIGO stage III cervical cancer patients versus chemoradiation and brachytherapy: Complications and 3-years survival.

BACKGROUND: To compare patterns and rates of early and late complications, and survival outcome in FIGO stage III cervical cancer patients underwent to radical hysterectomy after chemo-radiation (CT-RT) vs. chemo-radiation alone. METHODS: Between May 1996 and April 2013 150 FIGO stage III cervical cancer patients were treated. We divide patients according to type of treatment: 77 were submitted to standard treatment (Group A), and 73 to completion hysterectomy after chemo-radiation (Group B). RESULTS: The baseline characteristics of the 2 groups were superimposable. We observed lower intra-operative and treatment-related early urinary and gastro-intestinal complications in Group B with respect to Group A (p < 0.001). Vascular complications were registered only in Group B (p < 0.001). We found a significantly higher rate of local recurrences in the Group A than in the Group B (p < 0.002). We registered 29 deaths in the Group A and 22 in the Group B (p = 0.021). The 3-years disease-free survival rate in the Group A and in the Group B was 62.9% and 68.3%, respectively (p = 0.686), and the 3-years overall survival rate in the Group A and in the Group B was 63.2% and 67.7%, respectively (p = 0.675). CONCLUSIONS: This study confirms that radical hysterectomy after CT-RT is an effective therapeutic approach for advanced cervical cancer. Further prospective and randomized studies should be performed in order to solve the question about the standard approach, and how the different pattern of complication could impact on the quality of life.

Targeting immune response with therapeutic vaccines in premalignant lesions and cervical cancer: hope or reality from clinical studies.

Human papillomavirus (HPV) is widely known as a cause of cervical cancer (CC) and cervical intraepithelial neoplasia (CIN). HPVs related to cancer express two main oncogenes, i.e. E6 and E7, considered as tumorigenic genes; their integration into the host genome results in the abnormal regulation of cell cycle control. Due to their peculiarities, these oncogenes represent an excellent target for cancer immunotherapy. In this work the authors highlight the potential use of therapeutic vaccines as safe and effective pharmacological tools in cervical disease, focusing on vaccines that have reached the clinical trial phase. Many therapeutic HPV vaccines have been tested in clinical trials with promising results. Adoptive T-cell therapy showed clinical activity in a phase II trial involving advanced CC patients. A phase II randomized trial showed clinical activity of a nucleic acid-based vaccine in HPV16 or HPV18 positive CIN. Several trials involving peptide-protein-based vaccines and live-vector based vaccines demonstrated that these approaches are effective in CIN as well as in advanced CC patients. HPV therapeutic vaccines must be regarded as a therapeutic option in cervical disease. The synergic combination of HPV therapeutic vaccines with radiotherapy, chemotherapy, immunomodulators or immune checkpoint inhibitors opens a new and interesting scenario in this disease.

Surgical and oncological outcome of robotic surgery compared to laparoscopic and abdominal surgery in the management of endometrial cancer.

OBJECTIVE: To compare different techniques of minimally invasive surgery (laparoscopy and robotics) to abdominal surgery in order to identify the optimal surgical technique in the treatment of endometrial cancer. METHODS AND MATERIALS: A single-institutional, matched, retrospective, cohort study was performed. All patients with clinical stage I or occult stage II endometrial cancer who underwent robotic hysterectomy, bilateral salpingo-oophorectomy ± lymphadenectomy from August 2010 and December 2013 were identified. Surgical and oncological outcomes were compared with patients matched by age, body mass index, tumor histology, and grade, who underwent abdominal or laparoscopic surgery between January 2001 and December 2013. RESULTS: Three groups were identified: 177 laparotomies (group A), 277 laparoscopies (group B) and 72 robotics (group C). There were no statistically significant differences between the three groups in terms of age, BMI and FIGO stage. The operative time was shortest in group B (p = 0.0001). Blood loss and transfusions were equivalent in group B and C, while they were greater in group A (p = 0.0001). The intra-operative, early and late postoperative complications, rate of conversion, the re-intervention and median hospital stay were lower in group C. The rate of recurrence and death from disease was similar in all three groups. CONCLUSIONS: Minimally invasive surgery was superior to abdominal surgery in terms of surgical outcomes. Robotic surgery was superior to laparoscopy in terms of intra- and post-operative complications, conversion rates, length of hospital stay and re-interventions. In terms of oncological outcomes the three groups were equivalent.

Mini-laparoscopic versus robotic radical hysterectomy plus systematic pelvic lymphadenectomy in early cervical cancer patients. A multi-institutional study.

OBJECTIVE: The aim of this study was to verify possible differences in terms of perioperative outcomes and complications between mini-laparoscopic radical hysterectomy with lymphadenectomy (mLRH) and robotic radical hysterectomy with lymphadenectomy (RRH) in patients with early cervical cancer (ECC). MATERIAL AND METHODS: In this retrospective study, thirty women with early stage cervical cancer who underwent mini-laparoscopic radical hysterectomy plus lymphadenectomy (mLRH) were compared with a cohort of thirty women who underwent robotic multiport radical hysterectomy (RRH). The study involved patients, between August 2010 and December 2012, from three Italian institutions: National Cancer Institute of Rome, University of Insubria, Varese, and the Catholic University of the Sacred Heart of Rome. RESULTS: No significant differences between groups were observed in terms of age, BMI, previous abdominal surgery or FIGO stage. Operative time, blood loss, need of blood transfusion, risk of intra- and post-operative complications, and lymph nodes yield were similar between mLRH and RRH in patients with ECC. The median length of hospital stay was 2 days in the mLRH group and 3 days in the RRH group (p < 0.05). CONCLUSIONS: The few differences we registered do not seem clinically relevant, thus making the two procedures comparable. The decision on how to gain best access for radical hysterectomy considers the surgeon's skill and experience with the different possible approaches. Further randomized trials are needed to determine whether mini-laparoscopic techniques truly offer any advantages.

Laparoscopic versus robotic radical hysterectomy after neoadjuvant chemotherapy in locally advanced cervical cancer: a case control study.

OBJECTIVE: To compare the surgical outcome of robotic radical hysterectomy (RRH) versus laparoscopic radical hysterectomy (LRH) for the treatment of locally advanced cervical cancer (LACC) after neoadjuvant chemotherapy (NACT). MATERIALS AND METHODS: From August 1st 2010 to July 1st 2012 a prospective data collection of women undergoing RRH for cervical cancer stage FIGO IB2 to IIB, after neoadjuvant chemotherapy, was conducted at National Cancer Institute "Regina Elena" of Rome. All patients deemed operable underwent class C1 RRH with pelvic lymphadenectomy within 4 weeks from the last chemotherapy cycle. RESULTS: A total of 25 RRH were analyzed, and compared with 25 historic LRH cases. The groups did not differ significantly in body mass index, stage, histology, number of pelvic lymph nodes removed. The median operative time was the same in the two groups with 190 min respectively. The median estimated blood loss (EBL) was statistically significant in favor of RRH group. Median length of stay was shorter, for the RRH group (4 versus 6 days, P = 0.28). There was no significant difference in terms of intraoperative and postoperative complications between groups but in the RRH group we observed a greater number of total complications compared to the control group. CONCLUSION: This study shows that RRH is safe and feasible in LACC after NACT compare to LRH. However, a comparison of oncologic outcomes and cost-benefit analysis is still needed and it has to be carefully evaluated in the future.

Laparoscopic staging of apparent early stage ovarian cancer: results of a large, retrospective, multi-institutional series.

OBJECTIVE: The aim of this study is to analyze the safety, adequacy, perioperative and survival figures in a large series of laparoscopic staging of patients with apparent early stage ovarian malignancies (ESOM). PATIENTS AND METHODS: Retrospective data from seven gynecologic oncology service databases were searched for ESOM patients undergoing immediate laparoscopic staging or delayed laparoscopic staging after an incidental diagnosis of ESOM. Between May 2000 and February 2014, 300 patients were selected: 150 had been submitted to immediate laparoscopic staging (Group 1), while 150 had undergone delayed laparoscopic staging (Group 2) of ESOM. All surgical, pathologic, and oncologic outcome data were analyzed in each group and a comparison between the two was carried out. RESULTS: Longer operative time, higher blood loss, more frequently spillage/rupture of ovarian capsule and conversion to laparotomy occurred in Group 1. No significant differences of post-operative complications were observed between the two groups. Histological data revealed more frequently serous tumors (0.06), Grade 3 (p=0.0007) and final up-staging (p=0.001) in Group 1. Recurrence and death of disease were documented in 25 (8.3%), and 10 patients (3.3%%), respectively. The 3-year disease free survival (DFS) and overall survival (OS) rates were 85.1%, and 93.6%, respectively in the whole series. There was no difference between Group 1 and Group 2 in terms of DFS (p value=0.39) and OS (p value=0.27). CONCLUSION: In this very large multi-institutional study, it appears that patients with apparent ESOM can safely undergo laparoscopic surgical management.
