Feasibility and Surgical Outcomes of Hysteroscopic Myomectomy of FIGO Type 3 Myoma: A Systematic Review

The latest classification from the Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) has reclassified type 3 myomas, changing their classification from intramural to submucosal. While hysteroscopic myomectomy is considered the gold standard treatment for patients experiencing symptoms from submucosal myomas, there are currently no specific guidelines available for managing type 3 myomas, and the optimal surgical approach remains uncertain. Methods: The search for suitable articles published in English was carried out using the following databases (PROSPERO ID CRD42023418602): MEDLINE, EMBASE, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), Health Technology Assessment Database, Web of Science and search register. Only original studies reporting data on hysteroscopic myomectomy of type 3 myoma were considered eligible. The main outcomes investigated were the effectiveness and feasibility of hysteroscopic myomectomy and reproductive outcomes after surgical treatment. Results: Two hundred and sixty-one studies were screened and nineteen of these were read for eligibility. Three studies encompassing 56 patients in total were included. Among the overall population studied, three patients needed an additional procedure to completely remove the myoma and five cases of post-surgical synechiae were recorded. No complications were reported. Of 42 patients wishing for pregnancy, the cumulative live birth rates before and after the hysteroscopic myomectomy were 14.3% and 42.9%, respectively. Conclusions: Hysteroscopic myomectomy appears to be a safe and feasible approach. Nevertheless, data reported in the literature are extremely scarce and based on studies with few patients enrolled. New evidence is needed to assess the safety and effectiveness of hysteroscopic treatment for FIGO type 3 myomas.

Effect of maternal age and body mass index on induction of labor with oral misoprostol for premature rupture of membrane at term: A retrospective cross-sectional study

The aim of this study was to evaluate the effect of maternal age and body mass index (BMI) on induction of labor with oral misoprostol for premature rupture of membrane (PROM) at term. We have conducted retrospective cross-sectional study, including only term (37 weeks or more of gestation) PROM in healthy nulliparous women with a negative vaginal-rectal swab for group B streptococcus, a single cephalic fetus with normal birthweight, and uneventful pregnancy that were induced after 24 h from PROM. Ninety-one patients were included. According to the multivariate logistic regression, age and BMI odds ratio (OR) for induction success were 0.795 and 0.857, respectively. The study population was divided into two groups based on age (<35 and ≥35 years) and obesity (BMI <30 and ≥30). Older women reported a higher induction failure rate (p < 0.001); longer time to cervical dilation of 6 cm (p = 0.03) and delivery (p < 0.001). Obese women reported a higher induction failure rate (p = 0.01); number of misoprostol doses (p = 0.03), longer time of induction (p = 0.03) to cervical dilatation of 6 cm (p < 0.001), and delivery (p < 0.001); and higher cesarean section (p = 0.012) and episiotomy rate (p = 0.007). In conclusion, maternal age and BMI are two of the main factors that influence oral misoprostol efficacy and affect the failure of induction rate in term PROM.

COVID-19 and Pregnancy: An Updated Review about Evidence-Based Therapeutic Strategies

The COVID-19 pandemic posed a significant challenge for clinicians in managing pregnant women, who were at high risk of virus transmission and severe illness. While the WHO declared in May 2023 that COVID-19 is no longer a public health emergency, it emphasized that it remains a global health threat. Despite the success of vaccines, the possibility of new pandemic waves due to viral mutations should be considered. Ongoing assessment of the safety and effectiveness of pharmacological therapies is crucial in clinical practice. This narrative review summarizes the evidence-based therapeutic strategies for pregnant women with COVID-19, considering over three years of pandemic experience. The review discusses the safety and effectiveness of various drug regimens (antivirals, anticoagulants, corticosteroids, immunoglobulins, monoclonal antibodies, and therapeutic gases) and procedures (prone positioning and extracorporeal membrane oxygenation). Drugs with contraindications, inefficacy during pregnancy, or unknown adverse effects were excluded from our evaluation. The aim is to provide healthcare professionals with a comprehensive guide for managing pregnant women with COVID-19 based on lessons learned from the pandemic outbreak.

The Role of Micronutrients in Human Papillomavirus Infection, Cervical Dysplasia, and Neoplasm

There is evidence that diet and nutrition are modifiable risk factors for several cancers. In recent years, attention paid to micronutrients in gynecology has increased, especially regarding Human papillomavirus (HPV) infection. We performed a review of the literature up until December 2022, aiming to clarify the effects of micronutrients, minerals, and vitamins on the history of HPV infection and the development of cervical cancer. We included studies having as their primary objective the evaluation of dietary supplements, in particular calcium; zinc; iron; selenium; carotenoids; and vitamins A, B12, C, D, E, and K. Different oligo-elements and micronutrients demonstrated a potential protective role against cervical cancer by intervening in different stages of the natural history of HPV infection, development of cervical dysplasia, and invasive disease. Healthcare providers should be aware of and incorporate the literature evidence in counseling, although the low quality of evidence provided by available studies recommends further well-designed investigations to give clear indications for clinical practice.

Primary cutaneous interdigitating dendritic cell sarcoma (IDCS): Report of a new case and literature review

Interdigitating dendritic cell sarcoma is a very rare entity in the spectrum of histiocytic and dendritic cell neoplasms that mostly occurs in lymph nodes, generally presenting as solitary lymphadenopathy, but may affect every organ. Among extra nodal sites, cutaneous interdigitating dendritic cell sarcoma is exceedingly rare; to date, only 9 cases have been described in English literature. The mean age at diagnosis was 60 years, with a male-female ratio of 1,5 to 1; clinically, two different modalities of skin presentation have been reported: solitary, represented by a single red-brownish nodular lesion, or diffuse, characterized by multiple nodular lesions in one or more body districts. The extreme rarity of this sarcoma and its morphological similarity to other poorly differentiated tumors may lead to a delay in diagnosis; in particular, cutaneous localization may be difficult to differentiate from follicular dendritic cell sarcoma, Langerhans cell sarcoma, poorly differentiated squamous cell carcinoma and more generally sarcomatoid carcinoma, atypical fibroxanthoma, malignant melanoma and several sarcomas. Immunohistochemistry plays an important role in identifying this rare entity and formulating a correct histological diagnosis, fundamental requirement for choosing the best therapeutic approach. We report herein a further case of an 81-year-old Caucasian woman who presented to the Dermatology Department to remove an asymptomatic skin papule in the left temporal region, clinically diagnosed as dermatofibroma. The overall pathological and immunohistochemical features supported the diagnosis of a malignant dendritic cell tumor, consistent of interdigitating dendritic cell sarcoma.

Do Exophytic and Endophytic Patterns in Borderline Ovarian Tumors Have Different Prognostic Implications? A Large Multicentric Experience

Borderline ovarian tumor (BOT) accounts for 15-20% of all epithelial ovarian tumors. Concerns have arisen about the clinical and prognostic implications of BOT with exophytic growth patterns. We retrospectively reviewed all cases of BOT patients surgically treated from 2015 to 2020. Patients were divided into an endophytic pattern (with intracystic tumor growth and intact ovarian capsule) and an exophytic pattern (with tumor growth outside the ovarian capsule) group. Among the 254 patients recruited, 229 met the inclusion criteria, and of these, 169 (73.8%) belonged to the endophytic group. The endophytic group showed more commonly an early FIGO stage than the exophytic group (100.0% vs. 66.7%, p < 0.001). Furthermore, tumor cells in peritoneal washing (20.0% vs. 0.6%, p < 0.001), elevated Ca125 levels (51.7% vs. 31.4%, p = 0.003), peritoneal implants (0 vs. 18.3%, p < 0.001), and invasive peritoneal implants (0 vs. 5%, p = 0.003) were more frequently observed in the exophytic group. The survival analysis showed 15 (6.6%) total recurrences, 9 (5.3%) in the endophytic and 6 (10.0%) patients in the exophytic group (p = 0.213). At multivariable analysis, age (p = 0.001), FIGO stage (p = 0.002), fertility-sparing surgery (p = 0.001), invasive implants (p = 0.042), and tumor spillage (p = 0.031) appeared significantly associated with recurrence. Endophytic and exophytic patterns in borderline ovarian tumors show superimposable recurrence rates and disease-free survival.

Effects of neuraxial analgesia technique on labor and maternal-fetal outcomes: a retrospective study

PURPOSE

To compare the effects of epidural analgesia (EA) and combined spinal epidural analgesia (SEA) on labor and maternal-fetal outcomes.

METHODS

We retrospectively identified and included 1499 patients with a single cephalic fetus who delivered at the study center from January 2015 to December 2018 and received neuraxial analgesia at the beginning of the active phase of labor (presence of regular painful contractions and cervical dilatation between 4 and 6 cm). Data including analgesia, labor characteristics, and maternal-fetal outcomes were retrieved from the prospectively collected delivery room database and medical records.

RESULTS

SEA was associated with a shorter first stage of labor than EA, with a median difference of 60 min. On multivariable ordinal logistic regression analysis, neuraxial analgesia, gestational age, fetal weight, labor induction, and parity were independently associated with the first stage length: patients in the EA group were 1.32 times more likely to have a longer first stage of labor (95% CI 1.06-1.64, p = 0.012) than those in the SEA group. Additionally, a significantly lower incidence of fundal pressure was performed among patients who underwent SEA (OR 0.55, 95% CI 0.34-0.9, p = 0.017). No associations were observed between the used neuraxial analgesia technique and other outcomes.

CONCLUSIONS

SEA was associated with a shorter length of the first stage of labor and a lower rate of fundal pressure use than EA. Further studies confirming the effects of SEA on labor management and clarifying differences in maternal-fetal outcomes will allow concluding about the superiority of one technique upon the other.

Surgical Outcomes and Complications of Laparoscopic Hysterectomy for Endometriosis: a multicentric cohort study

STUDY OBJECTIVE

To investigate the postoperative morbidity of laparoscopic hysterectomy (LH) for endometriosis/adenomyosis in terms of operative outcomes and complications.

DESIGN

Retrospective multicentric cohort study.

SETTING

Eight European minimally invasive referral centers.

PATIENTS

Data from 995 patients with pathologically confirmed endometriosis and/or adenomyosis who underwent LH without concomitant urological and/or gastroenterological procedures from January 2010 to December 2020.

INTERVENTIONS

Total laparoscopic hysterectomy.

MEASUREMENTS AND MAIN RESULTS

Demographic patients' characteristics, surgical outcomes, and intraoperative and postoperative complications were evaluated. We considered major postoperative surgical-related complications any grade 2 or more events (Clavien-Dindo score) that occurred within 30 days from surgery. Univariate analysis and multivariable models fit with logistic regression were used to estimate the adjusted odds ratio (OR) and corresponding 95% CI for major complications. Median age at surgery was 44 years (28-54) and about half of them (505, 50.7%) were on medical treatment (estro-progestins, progestin or GnRh-analogues) at the time of surgery. In association with LH, posterior adhesiolysis was performed in 387 (38,9%) cases and deep nodule resection in 302 (30,0%). Intraoperative complications occurred in 3% of the patients and major postoperative complications were registered in 93 (9.3%). The multivariable analysis showed an inverse correlation between the occurrence of Clavien-Dindo >2 complications and age (OR 0.94, 95%CI 0.90-0.99), while previous surgery for endometriosis (OR 1.62, 95%CI 1.01-2.60) and intraoperative complications (OR 6.49, 95%CI 2.65-16.87) were found as predictors of major events. Medical treatment at the time of surgery has emerged as a protective factor (OR 0.50, 95%CI 0.31-0.81).

CONCLUSION

LH for endometriosis/adenomyosis is associated with non-negligible morbidity. Knowing the factors associated with higher risks of complications might be used for risk stratification and could help clinicians during preoperative counseling. The administration of estro-progestin or progesterone preoperatively might reduce the risks of postoperative complications following surgery.

Successful laparoscopic surgical removal of a caesarean scar pregnancy (CSP) using temporary uterine artery ligation

STUDY OBJECTIVE

To demonstrate a laparoscopic technique to remove a scar pregnancy.

DESIGN

Stepwise demonstration of the surgical technique.

SETTING

Santa Croce and Carle Hospital, Cuneo.

INTERVENTION

Patient B.B. is a woman referred to our center for a suspected cesarean scar pregnancy (CSP) at 9 weeks gestation. CSP occurs approximately in 6% of all ectopic pregnancies. The estimated incidence is reported to be 1:1800 to 1:2500 in cesarean deliveries. Depending on its location, CSP can be categorized as either type 1, if the growth is in the uterine cavity, or type 2, if it expands toward the bladder and the abdominal cavity. If inadequately managed, it can lead to severe complications; most of them are hemorrhagic and can threaten the woman's life. There are several therapeutic approaches: local excision seems to be the most effective choice in type 2 CSP. In expert hands, the laparoscopic approach is perhaps the best surgical choice as tissue dissection, electrosurgical hemostasis, and vascular control can be effectively managed with minimal invasive access. Because severe intraoperative bleeding can occur, retroperitoneal vascular control is mandatory in this surgery. In type 1 CSP curettage, aspiration or hysteroscopic approach can be considered if the CSP is of small dimensions. A hysteroscopic approach can also be helpful in type 2 CSP during the laparoscopic removal, as intrauterine guidance. A potassium chloride local injection can be considered in a preoperative stage in the presence of a fetal heart rate. The systemic administration of methotrexate is usually ineffective as single agent, but it can be useful if administered as adjuvant therapy. Uterine artery embolization can be useful in an emergency setting to manage severe bleeding, but it can lead to complications in subsequent pregnancies and, more rarely, to premature ovarian failure. Considering poor bleeding at presentation, feasible dimensions, and the woman's desire for future pregnancy, ultrasound-guided aspiration and curettage was attempted. Because endouterine removal was incomplete, methotrexate injection was proposed as adjuvant therapy, but the administration was postponed as the patient tested positive for coronavirus disease 2019. A month later, beta-human chorionic gonadotropin level dropped from over 16 000 to 271 mU/mL, so an ultrasound and biochemical follow-up was performed. A month later, despite a low beta-human chorionic gonadotropin value, an increase in dimensions was observed at ultrasound, so surgical laparoscopic removal was offered. In this video article, laparoscopic removal of scar pregnancy is discussed in the following surgical steps: (1) Temporary closure of uterine arteries at the origin, using removable clips. (2) Retroperitoneal dissection to safely manage the scar pregnancy. (3) Dissection of the myometrial-pregnancy interface. (4) Double layer suture on the anterior uterine wall.

CONCLUSION

Laparoscopic surgical management is a very effective surgical approach to remove CSP. Knowledge of retroperitoneal dissection and vascular control is necessary to carry out this surgical intervention safely and effectively.

COVID-19 and Pregnancy: Have We Gotten through the Darkest Hour?

On December 2019, a new Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) was isolated and identified in Wuhan (China) [...].

Risk perception and affective state on work exhaustion in obstetrics during the COVID-19 pandemic

A multicenter cross-sectional survey study involving four Italian University Hospitals was performed to test the hypothesis that negative affect and positive affect (affective dimensions) mediate the association between risk perception (perceived risk of infection and death; cognitive dimensions) and the feeling of work exhaustion (WE) among obstetrics healthcare providers (HCPs) during the Coronavirus Disease 2019 (COVID-19) pandemic. Totally, 570 obstetrics HCPs were invited to complete the 104-item IPSICO survey in May 2020. A theoretical model built on the tested hypothesis was investigated by structural equation modelling. The model explained 32.2% of the WE variance. Only negative affect mediated the association between cognitive dimensions and WE and also the association between WE and psychological well-being before the pandemic, experiences of stressful events, female gender, and dysfunctional coping. Non-mediated associations with WE were observed for work perceived as a duty, experience of stressful events, support received by colleagues, and the shift strategy. Only previous psychological well-being, support by colleagues, and shift strategies were inversely associated with WE. Based on study results, monitoring negative than positive affect appears superior in predicting WE, with practical implications for planning psychological interventions in HCPs at the individual, interpersonal, and organizational levels.

Conservative Management of Atypical Endometrial Hyperplasia and Early Endometrial Cancer in Childbearing Age Women

Total hysterectomy and bilateral adnexectomy is the standard treatment for atypical endometrial hyperplasia and early-stage endometrial cancer. However, the recommended surgical treatment precludes future pregnancy when these conditions are diagnosed in women in their fertile age. In these patients, fertility-sparing treatment may be feasible if the desire for childbearing is consistent and specific conditions are present. This review summarizes the available evidence on fertility-sparing management for atypical endometrial hyperplasia and early-stage endometrial cancer. Historically, oral progestins have been the mainstay of conservative management for atypical endometrial hyperplasia and stage IA endometrioid endometrial cancer with no myometrial invasion, although there is no consensus on dosage and treatment length. Intrauterine progestin therapy has proved a valid alternative option when oral progestins are not tolerated. GnRH analogs, metformin, and hysteroscopic resection in combination with progestins appear to increase the overall efficacy of the treatment. After a complete response, conception is recommended; alternatively, maintenance therapy with strict follow-up has been proposed to decrease recurrence. The risk of disease progression is not negligible, and clinicians should not overlook the risk of hereditary forms of the disease in young patients, in particular, Lynch syndrome. Hysterectomy is performed once the desire for childbearing desire has been established. The conservative management of atypical endometrial hyperplasia and early-stage endometrial cancer is feasible, provided a strong desire for childbearing and permitting clinical-pathological conditions. However, patients must be aware of the need for a strict follow-up and the risk of progression with a possible consequent worsening of the prognosis. More homogenous and well-designed studies are necessary to standardize and identify the best treatment and follow-up protocols.

Isolated tumour cells in a sentinel lymph node of apparent early-stage ovarian cancer: Ultrastaging of all other 27 lymph nodes

•

Sentinel node is a promising possibility for retroperitoneal lymphatic staging in apparently early ovarian cancer.

•

We describe a patient with Isolated tumor cells (ITCs) in one sentinel node with all the other nodes negative at ultrastaging.

•

It is likely that the technique of sentinel node in early ovarian cancer is able to identify the real lymphatic drainage of the ovary.

•

This report represents a proof of concept in support of the use of sentinel node in apparently early ovarian cancer.

Sentinel lymph node (SLN) biopsy in apparent early-stage ovarian cancer may spare the surgical staging with extensive retroperitoneal dissection and its associated morbidity. However, SLN biopsy in ovarian cancer is still experimental and under investigation. A 46-year-old post-menopausal woman with bilateral apparent stage IC1 endometrioid ovarian cancer underwent surgical staging by SLN biopsy and subsequent comprehensive laparoscopic pelvic and para-aortic lymphadenectomy. Out of 4 SLNs submitted to ultrastaging, one was positive for isolated tumour cells (ITCs). We submitted to ultra-staging all the other 24 pelvic and para-aortic non-SLNs, which were reported negative for disease. This is the first reported case of comprehensive lymphadenectomy after SLN biopsy with universal ultrastaging of all non-SLNs in ovarian cancer. The presence of ITCs in only one SLN, with all other 27 lymph nodes negative at ultrastaging, is consistent with the SLN concept and the assumption of a reliable lymphatic pathway in ovarian cancer.

Female Sexual Dysfunctions and Urogynecological Complaints: A Narrative Review

Female sexual dysfunctions represent a real widespread problem, usually faced from a psychological point of view; however, millions of women worldwide are impacted by pelvic floor dysfunction, personal shame and social taboos, however, continue to inhibit free conversation on the subject. Women's quality of life is considerably improved by screening, diagnosing, and controlling urogenital and sexual issues. This review aims to provide a critical perspective of urogenital conditions and common disturbances in female sexual function associated with these issues. It also includes a discussion of postpartum pelvic dysfunction.

Transvaginal versus port-site specimen retrieval after laparoscopic myomectomy: a systematic review and meta-analysis

INTRODUCTION

To date, there is no robust evidence suggesting whether transvaginal (TVSR) or port-site specimen retrieval (PSSR) after laparoscopic myomectomy (LM) may lead to better surgical outcomes. Considering this element, we aimed to compare surgical outcomes of TVSR versus PSSR after LM.

METHODS

A search (PROSPERO ID: CRD42020176490) of international databases, from 1980 to 2020, in English language, was conducted. We selected studies that included women who underwent LM with TVSR compared with PSSR.

RESULTS

We did not find significant differences for operative time (MD=-8.90 [95% CI -30.00, 12.20]; I2=87%), myoma retrieval time (MD=-1.85 [95% CI -13.55, 9.85]; I2=98%), blood loss (MD=-27.62 [95% CI -178.68, 124.43]; I2=91%), intra-operative complication rate (OR 0.51, 95% CI 0.01-23.09; I2=69%) and hospital stay (MD=-0.14 [95% CI -0.43; 0.15]; I2=64%); we found a significant lower post-operative rescue analgesics utilization in the TVSR group compared with the PSSR group (OR 0.31, 95% CI 0.16-0.61, I2=0).

CONCLUSION

TVSR and PSSR after LM showed comparable results for operative time and surgery-related complications. However, the need of post-operative rescue analgesics was lower in women who underwent TVSR.

See-and-treat in-office hysteroscopy versus operative hysteroscopy for the treatment of retained products of conception: A retrospective study

AIM

To compare the efficacy and safety of in-office hysteroscopy with a see-and-treat approach with that of operative hysteroscopy for the treatment of retained products of conception (RPOC).

METHODS

We retrospectively identified all consecutive patients who underwent hysteroscopic treatment of RPOC between 2015 and 2019. We excluded patients with RPOC larger than 2 cm at preoperative transvaginal ultrasounds. Between 2015 and 2017, all hysteroscopic removals of RPOC were performed by operative hysteroscopy. Between 2018 and 2019, all cases of RPOC less than 2 cm in size were hysteroscopically removed by the see-and-treat approach in the office setting. Sociodemographic, clinical, and procedure characteristics along with complications were retrieved from medical records.

RESULTS

Between 2015 and 2019, 119 women underwent hysteroscopic removal of RPOC equal to or smaller than 2 cm: 53 patients by in-office hysteroscopy, and 66 by operative hysteroscopy. The two groups were similar in preoperative characteristics. Although the time required to complete the RPOC removal was similar, the total procedure and assistant time were significantly higher in the operative hysteroscopy group (p < 0.001). Moreover, operative hysteroscopy was associated with a higher proportion of cases complicated by excessive bleeding, cervical tear, or uterine perforation (p = 0.016). Failure to complete the procedure was similarly reported in the two groups (p = 0.58).

CONCLUSIONS

In-office hysteroscopy with the see-and-treat approach for RPOC equal to or smaller than 2 cm appears as effective as operative hysteroscopy, but safer. In-office hysteroscopy may be considered the first choice for treating RPOC equal to or smaller than 2 cm.

Estrogeni e infiammazione

L’infiammazione è un processo essenziale per la vita, modulato da meccanismi immunoneuroendocrini. In questa Rassegna si analizza il ruolo degli estrogeni naturali umani (estradiolo, estrone, estriolo ed estetrolo) nella regolazione dell’infiammazione, facendo riferimento alla loro interazione con gli altri steroidi sessuali (progesterone e androgeni) nella modulazione di tale processo. L’infiammazione può essere fisiologica, quando è finalizzata (resolving), di breve durata, di intensità limitata e termina con restitutio ad integrum. È patologica quando perde tali caratteristiche diventando non finalizzata, non risolutiva (non resolving), di variabile intensità, con andamento cronico e progressiva distruzione tissutale. Durante la vita fertile della donna si manifestano tre eventi infiammatori fisiologici pertinenti alla sfera riproduttiva: l’ovulazione, la mestruazione e il parto. Tutti e tre sono strettamente correlati con le oscillazioni dei livelli di estrogeni, nonché del progesterone e degli androgeni. L’azione degli estrogeni nei confronti dell’infiammazione è molto articolata, in rapporto al tipo di estrogeno considerato, all’andamento dei suoi livelli plasmatici (fluttuante versus stabile) e al tipo di interazione con i recettori estrogenici, in particolare di tipo \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\alpha $\end{document}α e \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\beta $\end{document}β. Le fluttuazioni estrogeniche, in particolare dell’estradiolo, influiscono sulla presenza e l’attivazione delle varie classi di cellule immunitarie nell’endometrio e a livello sistemico. Accanto agli estrogeni, progesterone e androgeni rivestono un ruolo immunomodulatorio, con prevalenza anti-infiammatoria. La concisa descrizione delle complesse interazioni tra i diversi tipi di estrogeni e il sistema immunitario è stata fatta privilegiando gli aspetti più attinenti alla pratica clinica quotidiana dell’endocrinologo/a.

Cervical versus utero-ovarian ligament injection of the tracer for the pelvic sentinel lymph node mapping in gynecologic oncology: a prospective observational study

OBJECTIVE

In gynecologic oncology, the consolidated injection site for the pelvic sentinel lymph node mapping is the cervix. However, in apparent early-stage ovarian cancer, current trials map the pelvic area injecting the tracers in the utero-ovarian ligament. A different injection site is proposed based on a possible different lymphatic ovarian drainage through the utero-ovarian ligament and uterus and consequently a different pelvic sentinel lymph node mapping than the cervix; however, this was never proven. On that basis, this study aimed to investigate whether injecting the tracer in the utero-ovarian ligament map the same or a different pelvic sentinel lymph node than the cervix.

DESIGN

Prospective observational study.

METHODS

All consecutive women undergoing primary surgery for gynecologic malignancy with planned pelvic sentinel lymph node mapping were enrolled. The cervical injection was performed at 3 and 9 o'clock injecting indocyanine green. Bilateral utero-ovarian ligament injection was performed injecting methylene blue. The probability of detecting the same sentinel lymph node (concordance rate) and the probability of detecting a different sentinel lymph node (discordance rate) in each hemipelvis were compared using the McNemar's exact test.

RESULTS

Out of 36 hemipelvis (18 patients), the overall detection rate with cervical indocyanine green injection was 86.1% (31/36) versus 52.8% (19/36) with utero-ovarian ligament methylene blue injection (p=0.0004). Indocyanine green and methylene blue identified the same sentinel lymph node in all hemipelvis when sentinel lymph node mapping was obtained by both dyes (19/19; concordance rate 100%). No different or additional sentinel lymph nodes were identified by one of the two dyes (0/19; discordance rate 0%). The probability of detecting the same pelvic sentinel lymph node by the two injections sites was significantly higher than the probability of detecting a different pelvic sentinel lymph node (p<0.0001).

LIMITATIONS

The use of two different dyes with known different sentinel lymph node mapping performance impedes to evaluate differences in detection rate attributable to the two injection sites, limiting the comparison only in hemipelvis in which both dyes identified a sentinel lymph node.

CONCLUSIONS

Cervix and utero-ovarian ligament are two sites for the tracer injection that have a higher probability of detecting the same than a different pelvic sentinel lymph node. Given the higher technical challenge in performing the utero-ovarian ligament injection, these results suggest that the injection of the tracer into the cervix could be a more reliable alternative for the pelvic sentinel lymph node mapping in ovarian cancer.

SARS-CoV-2 detection in primary thyroid sarcoma: coincidence or interaction?

INTRODUCTION

Thyroid dysfunctions associated with SARS-CoV-2 are emerging in scientific literature. During the second COVID-19 epidemic spread, we evaluated a patient with the suspect of subacute thyroiditis.

METHODS AND RESULTS

Specimen from fine-needle aspiration of a hypoechoic undefined area was analyzed for cytology and for SARS-CoV-2 detection. SARS-CoV-2 was retrieved by real-time polymerase chain reaction on the cytologic sample, which was then cultured on Vero E6 cells and demonstrated to be cytopathic. Whole-genome sequence was deposited. Histological exam diagnosed a rare case of primary thyroid sarcoma with diffuse and strong expression of mouse double minute 2 homolog (MDM2) oncoprotein. Ultrastructural examination confirmed, in several neoplastic cells, the presence of viral particles in cytoplasmic vacuoles.

CONCLUSIONS

In our hypothesis, SARS-CoV-2 and sarcoma coexistence could represent a synergistic interplay, ultimately favoring both viral persistence and tumor proliferation: the overexpression of MDM2 in tumor cells might have generated a favorable immunological niche for SARS-CoV-2 localization and, in turn, SARS-CoV-2 could have favored tumor growth by inducing MDM2-mediated p53 downregulation. Functional studies are needed to confirm this suggestive pathway.

Different Surgical Approaches for Early-Stage Ovarian Cancer Staging. A Large Monocentric Experience

Introduction

Ovarian cancer is the third most frequent gynecological cancer. In early stage ovarian cancer (ESOC) comprehensive surgical staging is recommended. Surgical staging is traditionally approached by laparotomy, although minimally invasive surgery can be a valid alternative in selected patients. This study aims to analyze the surgical and oncological outcomes of three different surgical approaches in a large series of patients.

Methods

We retrospectively included all histologically proven ESOC cases treated between January 2014 and December 2017. ESOC was defined as stage IA to IIB according to the 2018 FIGO staging system. Subjects were divided into groups 1, 2, and 3, based on the surgical approach (open abdominal, laparoscopic, or robotic, respectively).

Results

Within patients enrolled during the study period, 455 met the inclusion criteria. No difference in intraoperative complications was recorded in the three groups (p = 0.709). Conversely, a significant difference occurred in postoperative complications (16.2 vs. 3.8 vs. 11.1%, in groups 1, 2, and 3 respectively, p = 0.004). No difference was found in overall survival (OS) (32 vs. 31 vs. 25 months, p = 0.481) and disease-free survival (DFS) (26 vs. 29 vs. 24 months, p = 0.178) in groups 1, 2, and 3, respectively. At univariate analysis FIGO stage I (p = 0.004) showed a lower recurrence rate compared to FIGO stage II.

Conclusion

No significant difference was found in OS and DFS among the three groups (open, laparoscopic, and robotic). The minimally invasive approach showed lower rate of complications than the laparotomic approach.
