Pharmacotherapy in patients with vasomotor disorders.

Background: Anginal symptoms in patients with non-obstructive coronary artery disease are frequently related to vasomotor disorders of the coronary circulation. Although frequently overlooked, a distinct diagnosis of different vasomotor disorders can be made by intracoronary function testing. Early detection and treatment seems beneficial, but little evidence is available for the medical treatment of these disorders. Nevertheless, there are several pharmacotherapeutic options available to treat these patients and improve quality of life. Methods & findings: We performed an extensive yet non-systematic literature search to explore available pharmacotherapeutic strategies for addressing vasomotor disorders in individuals experiencing angina and non-obstructive coronary artery disease. This article presents a comprehensive overview of therapeutic possibilities for patients exhibiting abnormal vasoconstriction (such as spasm) and abnormal vasodilation (like coronary microvascular dysfunction). Conclusion: Treatment of vasomotor disorders can be very challenging, but a general treatment algorithm based on the existing evidence and the best available current practice is feasible.

The prognostic value of the presence of pelvic and/or para-aortic lymph node metastases in cervical cancer patients; the influence of the new FIGO classification (stage IIIC).

INTRODUCTION: One of the major changes in the revised (2018) FIGO-staging system is the addition of stage IIIC to the previously used 2009 system. We evaluated the prognostic value of positive pelvic and/or para-aortic lymph nodes in patients with cervical cancer. METHODS: A nationwide retrospective cohort study was performed by analyzing data from the Netherlands Cancer Registry. All patients newly diagnosed with stage IB-IVA between 2005 and 2018 were identified. Three-year, 5-year and 15-year overall survival (OS) rates were estimated with the Kaplan-Meier method. RESULTS: Of the included 6082 patients, 1740 patients (29%) had pelvic and/or para-aortic lymph node metastases. For patients with FIGO 2009 stage IB-IB1-IIA-IIA1 and stage IB2-IIA2-IIB with pelvic and/or para-aortic lymph node metastases the OS was significantly different (p < 0.001 and p = 0.009), with a 5-year OS of 77% and 67%, compared with 92% and 74% for women without lymph node metastases. For FIGO 2009 stage IIIA-IIIB-IVA with and without lymph node metastases, survival rates are not significantly different (p = 0.064). For FIGO 2018 stage IIIC the 3y-OS, 5y-OS and 15-year OS are 72%, 65% and 59% respectively. Survival rates of IIIC diagnosed based on imaging (IIICr) are significantly impaired compared to stage IIIC diagnosed based on pathology (IIICp) (p < 0.001). CONCLUSION: Patients with FIGO 2009 stage IB-IIB cervical cancer with pelvic and/or para-aortic lymph node metastases have significantly impaired survival compared to patients without metastases. Survival rates of patients with FIGO 2009 stage IIIA-IVA are not affected by lymph node metastases.

The potential of RAS/RAF/MEK/ERK (MAPK) signaling pathway inhibitors in ovarian cancer: A systematic review and meta-analysis.

BACKGROUND: The RAS/RAF/MEK/ERK (MAPK) pathway plays a role in ovarian carcinogenesis. Low-grade serous ovarian carcinoma (LGSOC) frequently harbors activating MAPK mutations. MAPK inhibitors have been used in small subsets of ovarian carcinoma (OC) patients to control tumor growth. Therefore, we performed a meta-analysis to evaluate the effectiveness of MAPK inhibitors in OC patients. We aimed to determine the clinical benefit rate (CBR), the subgroup of MAPK inhibitors with the best CBR and overall response rate (ORR), and the most common adverse events. METHODS: We conducted a search in PubMed, Embase via Ovid, the Cochrane library and clinicaltrials.gov on studies evaluating the efficacy of single MAPK pathway inhibition with MAPK pathway inhibitors in OC patients. Our primary outcome included the CBR, defined by the proportion of patients with stable disease (SD), complete (CR) and partial response (PR). Secondary outcomes included the ORR (including PR and CR) and grade 3 and 4 adverse events. Meta-analysis was performed using a random-effects model. RESULTS: We included nine studies with a total of 319 OC patients, for which we determined a pooled CBR of 63% (95%-CI 39-84%, I2 = 92%). Combined treatment with Raf- and MEK inhibitors in in BRAFv600 mutated LGSOC (n = 6) had the greatest efficacy with a CBR of 100% and ORR of 83%. MEK inhibitors had the best efficacy as a single agent. Subgroup analysis by tumor histology demonstrated a significantly higher CBR and ORR in patients with LGSOC, with a pooled CBR and ORR of 87% (95%-CI 81-92%, I2 = 0%) and 27% (95%-CI 10-48%, I2 = 77%) respectively. Adverse events of grade 3 or higher were reported frequently: 123 in 167 patients. CONCLUSIONS: MEK inhibitors are the most promising single agents in (LGS)OC. However, dual MAPK pathway inhibition should be considered in patients with a BRAFv600 mutation, or non-mutated OC with depleted treatment options due indications of higher efficacy and tolerable toxicity profiles.

The effect of opportunistic salpingectomy for primary prevention of ovarian cancer on ovarian reserve: a systematic review and meta-analysis.

BACKGROUND: Opportunistic salpingectomy (OS) is an attractive method for primary prevention of ovarian cancer. Although OS has not been associated with a higher complication rate, it may be associated with earlier onset of menopause. OBJECTIVE: To provide a systematic review and meta-analysis of the effect of OS on both age at menopause and ovarian reserve. METHODS: A search was conducted in the Cochrane Library, Embase and MEDLINE databases from inception until March 2022. We included randomized clinical trials and cohort studies investigating the effect of OS on onset of menopause and/or ovarian reserve through change in anti-Müllerian hormone (AMH), antral follicle count (AFC), estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH). Data was extracted independently by two researchers. Random-effects meta-analyses were conducted to estimate the pooled effect of OS on ovarian reserve. RESULTS: The initial search yielded 1047 studies. No studies were found investigating the effect of OS on age of menopause. Fifteen studies were included in the meta-analysis on ovarian reserve. Meta-analyses did not result in statistically significant differences in mean change in AMH (MD -0.07 ng/ml, 95%CI -0.18;0.05), AFC (MD 0.20 n, 95 % CI -4.91;5.30), E2 (MD 3.97 pg/ml, 95%CI -0.92;8.86), FSH (MD 0.33mIU/ml, 95%CI -0.15;0.81) and LH (MD 0.03mIU/ml; 95%CI -0.47;0.53). CONCLUSION: Our study shows that OS does not result in a significant reduction of ovarian reserve in the short term. Further research is essential to confirm the absence of major effects of OS on menopausal onset since clear evidence on this subject is lacking. Registration number PROSPERO CRD42021260966.

Adjuvant Use of PlasmaJet Device During Cytoreductive Surgery for Advanced-Stage Ovarian Cancer: Results of the PlaComOv-study, a Randomized Controlled Trial in The Netherlands.

OBJECTIVE: Standard surgical treatment of advanced-stage ovarian carcinoma with electrosurgery cannot always result in complete cytoreductive surgery (CRS), especially when many small metastases are found on the mesentery and intestinal surface. We investigated whether adjuvant use of a neutral argon plasma device can help increase the complete cytoreduction rate. PATIENTS AND METHODS: 327 patients with FIGO stage IIIB-IV epithelial ovarian cancer (EOC) who underwent primary or interval CRS were randomized to either surgery with neutral argon plasma (PlasmaJet) (intervention) or without PlasmaJet (control group). The primary outcome was the percentage of complete CRS. The secondary outcomes were duration of surgery, blood loss, number of bowel resections and colostomies, hospitalization, 30-day morbidity, and quality of life (QoL). RESULTS: Complete CRS was achieved in 119 patients (75.8%) in the intervention group and 115 patients (67.6%) in the control group (risk difference (RD) 8.2%, 95% confidence interval (CI) -0.021 to 0.181; P = 0.131). In a per-protocol analysis excluding patients with unresectable disease, complete CRS was obtained in 85.6% in the intervention group and 71.5% in the control group (RD 14.1%, 95% CI 0.042 to 0.235; P = 0.005). Patient-reported QoL at 6 months after surgery differed between groups in favor of PlasmaJet surgery (95% CI 0.455-8.350; P = 0.029). Other secondary outcomes did not differ significantly. CONCLUSIONS: Adjuvant use of PlasmaJet during CRS for advanced-stage ovarian cancer resulted in a significantly higher proportion of complete CRS in patients with resectable disease and higher QoL at 6 months after surgery.

Coronary computed tomographic angiography as gatekeeper for new-onset stable angina.

Patients with new-onset stable angina constitute a substantial part of the population seen by cardiologists. Currently, the diagnostic workup of these patients depends on the pre-test probability of having obstructive coronary artery disease. It consists of either functional testing for myocardial ischaemia or anatomical testing by using coronary computed tomographic angiography (CCTA) or invasive coronary angiography. In case the pre-test probability is > 5%, the current guidelines for the management of chronic coronary syndromes do not state a clear preference for one of the noninvasive techniques. However, based on the recently published cost-effectiveness analysis of the PROMISE trial and considering the diagnostic yield in patients with angina and nonobstructive coronary artery disease, we argue a more prominent role for CCTA as a gatekeeper for patients with new-onset stable angina.

Ovarian cancer risk after salpingectomy for ectopic pregnancy or hydrosalpinx: results of the OCASE nationwide population-based database study.

STUDY QUESTION: What is the effect of salpingectomy for ectopic pregnancy or hydrosalpinx at a young age on ovarian cancer risk compared to no salpingectomy for any reason? SUMMARY ANSWER: We found no significant reduction in ovarian cancer risk after salpingectomy for ectopic pregnancy or hydrosalpinx. WHAT IS KNOWN ALREADY: Salpingectomy may reduce ovarian cancer incidence, although the lag-time between intervention and therapeutic effect remains to be elucidated. STUDY DESIGN, SIZE, DURATION: This nationwide population-based database study uses the Dutch pathology database to identify all women who underwent salpingectomy for ectopic pregnancy or hydrosalpinx between January 1990 and December 2012 and compared ovarian cancer incidence to a control group of women who had a benign dermal nevus removed, matched for age at the time and year of procedure. PARTICIPANTS/MATERIALS, SETTING, METHODS: After selection and manual control of intervention and control group, ovarian cancer incidence was recorded. Hazard ratios (HRs) with 95% CI for the development of ovarian cancer were calculated with Cox regression analyses, both unadjusted and adjusted for age. Subgroup analyses were performed to investigate lag-time between intervention and protective effect. MAIN RESULTS AND THE ROLE OF CHANCE: In all, 18 961 women were included in the intervention group; 17 106 women had a unilateral salpingectomy and 1855 had a bilateral salpingectomy. The control group consisted of 23 686 women. With 14 ovarian cancer cases in the intervention group, the incidence rate (IR) of ovarian cancer was 5.4 (95% CI 3.1-8.9) per 100 000 person-years. In the control group, there were 24 ovarian cancer cases, resulting in an IR of 7.1 (95% CI 4.7-10.5) per 100 000 person-years (P = 0.34). The age-adjusted HR for ovarian cancer was 0.76 (95% CI 0.39-1.47) after salpingectomy. Unilateral salpingectomy resulted in an age-adjusted HR of 0.81 (95% CI 0.41-1.59) and bilateral salpingectomy resulted in an age-adjusted HR of 0.43 (95% CI 0.06-3.16) based on one case. None of our subgroup analysis for lag-time resulted in a significant difference in ovarian cancer incidence between intervention and control group. The difference in ovarian cancer incidence appeared largest in women with at least 8 years of follow-up (P = 0.08). LIMITATIONS, REASONS FOR CAUTION: Due to the young population, ovarian cancer incidence is low, even at the end of follow-up. Furthermore, due to the anonymous nature of the pathology registry, we were unable to adjust for confounding factors. WIDER IMPLICATIONS OF THE FINDINGS: Although results did not reach statistical significance, they add to the available data on ovarian cancer incidence after salpingectomy. Our subgroup analysis suggests there may be no benefit in the first years following salpingectomy. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: N/A.

Ischaemia with no obstructive coronary arteries.

Ischaemia with no obstructive coronary arteries (INOCA) is a common ischaemic heart disease with a female preponderance, mostly due to underlying coronary vascular dysfunction comprising coronary microvascular dysfunction and/or epicardial coronary vasospasm. Since standard ischaemia detection tests and coronary angiograms are not suitable to diagnose coronary vascular dysfunction, INOCA is often overlooked in current cardiology practice. Future research, including large outcome trials, is much awaited. Yet, adequate diagnosis is possible and treatment options are available and vital to reduce symptoms and most probably improve cardiovascular prognosis. This review intends to give a brief overview of the clinical presentation, underlying pathophysiology, and the diagnostic and treatment options in patients with suspected INOCA.

Invasive coronary physiology: a Dutch tradition.

Invasive coronary physiology has been applied since the early days of percutaneous transluminal coronary angioplasty, and has become a rapidly emerging field of research. Many physiology indices have been developed, tested in clinical studies, and are now applied in daily clinical practice. Recent clinical practice guidelines further support the use of advanced invasive physiology methods to optimise the diagnosis and treatment of patients with acute and chronic coronary syndromes. This article provides a succinct review of the history of invasive coronary physiology, the basic concepts of currently available physiological parameters, and will particularly highlight the Dutch contribution to this field of invasive coronary physiology.
