Ovarian endometrioid carcinoma with a sex cord-like pattern: a morphological, immunohistochemical, and molecular analysis. Virchows Arch 2024:10.1007/s00428-024-03743-6. [PMID: 38418687 DOI: 10.1007/s00428-024-03743-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 01/03/2024] [Accepted: 01/15/2024] [Indexed: 03/02/2024]
Abstract
Sex cord-like endometrioid carcinoma (SCLEC) is an uncommon entity which may constitute a diagnostic challenge. This study aimed to perform a clinicopathological, immunohistochemical, and molecular reappraisal of ovarian SCLEC. Consecutive ovarian SCLECs cases from a single institution were reviewed during a 13-year period. Twenty-three immunohistochemical markers were tested; 10 genes were analyzed by next-generation sequencing. Nine cases of ovarian SCLEC were identified. Mean patient age was 65.7 years; three cases showed extraovarian extension. Architectural pattern included sertoliform (n = 2), granulosa-like (n = 2), and mixed granulosa-like/sertoliform (n = 5). Eosinophilic changes accompanied by increased nuclear atypia were observed in four tumors. Endometrioid features (glands, squamous/morular differentiation) were observed in six cases. Most tumors were positive for cytokeratin-7 (8/9), EMA (9/9), estrogen and progesterone receptor (9/9), CD10 (7/9, including a luminal pattern reminiscent of mesonephric neoplasms), nuclear β-catenin (8/9), and CDX2 (8/9). A minority of cases showed block-type p16 pattern (2/9), PAX8-positivity (3/9), and non-diffuse positivity for WT1 (1/9), inhibin (1/9), chromogranin (1/9), and synaptophysin (2/9). All cases were negative for GATA3, TTF1, calretinin, and SF1. Ki67 range was 15-90%. Six cases showed CTNNB1 exon 3 mutation. Eight cases were of "no specific molecular profile" (NSMP) and one was p53-abnormal. In conclusion, SCLECs frequently exhibit a mixed sertoliform/granulosa-like architecture and express epithelial markers, hormone receptors, nuclear β-catenin, and CDX2, with luminal CD10 positivity and CTNNB1 mutations. PAX8 expression is often lost, while other mesonephric, sex cord, and neuroendocrine markers are negative.

High-grade serous ovarian carcinoma with a sertoliform pattern associated with BRCA mutation: a clinicopathological and molecular analysis. Virchows Arch 2023; 483:879-883. [PMID: 37166561 DOI: 10.1007/s00428-023-03556-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 04/05/2023] [Accepted: 04/27/2023] [Indexed: 05/12/2023]
Abstract
Herein, we report a clinicopathological and molecular analysis of a case of tubo-ovarian high-grade serous carcinoma (HGSC) with a sertoliform pattern. A 45-year-old woman underwent surgery due to an advanced bilateral adnexal carcinoma with peritoneal and appendiceal metastases. Histological examination revealed an HGSC exhibiting a distinct sertoliform component. Such component showed diffuse PAX8, p53 (mutation-type), and p16 (block-type) expression, increased vimentin and decreased WT1 expression compared to the conventional HGSC component, membrane β-catenin positivity, heterogeneous estrogen, and progesterone positivity, and retained PTEN and mismatch repair expression and negativity for GATA3, TTF1, inhibin, calretinin, CD10, CDX2, chromogranin, and synaptophysin. Molecular analysis showed a germline BRCA2 mutation; no mutations were detected in POLE, POLD1, MLH1, MSH2, MSH6, PMS2, APC, CTNNB1, MUTYH, and EPCAM. In conclusion, a sertoliform pattern can be part of the morphological spectrum of BRCA-related HGSC.

Prognostic Value of Mandard's Tumor Regression Grade (TRG) in Post Chemo-Radiotherapy Cervical Cancer. Diagnostics (Basel) 2023; 13:3228. [PMID: 37892049 PMCID: PMC10605878 DOI: 10.3390/diagnostics13203228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 10/06/2023] [Accepted: 10/11/2023] [Indexed: 10/29/2023] Open
Abstract
In locally advanced cervical cancer (LACC), definitive chemo-radiotherapy is the standard treatment, but chemo-radiotherapy followed by surgery could be an alternative choice in selected patients. We enrolled 244 patients affected by LACC and treated with CT-RT followed by surgery in order to assess the prognostic role of the histological response using the Mandard scoring system. Results: A complete pathological response (TRG 0) was observed in 118 patients (48.4%), rare residual cancer cells (TRG2) were found in 49 cases (20.1%), increased number of cancer cells but fibrosis still predominating (TRG3) in 35 cases (14.3%), and 42 (17.2%) were classified as non-responders (TRG4-5). TRG was significantly associated with both OS (p < 0.001) and PFS (p < 0.001). The survival curves highlighted two main prognostic groups: TRG1-TRG2 and TRG3-TRG4-5. Main responders (TRG1-2) showed a 92% 5-year overall survival (5y-OS) and a 75% 5-year disease free survival (5y-DFS). Minor or no responders showed a 48% 5y-OS and a 39% 5y-DFS. The two-tiered TRG was independently associated with both DFS and OS in Cox regression analysis. Conclusion. We showed that Mandard TRG is an independent prognostic factor in post-CT/RT LACC, with potential benefits in defining post-treatment adjuvant therapy.

Ectrodactyly-ectodermal dysplasia-clefting syndrome. Prenatal prospective ultrasound diagnosis. JOURNAL OF CLINICAL ULTRASOUND : JCU 2023; 51:1348-1355. [PMID: 37665243 DOI: 10.1002/jcu.23549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 07/31/2023] [Accepted: 08/14/2023] [Indexed: 09/05/2023]
Abstract
OBJECTIVE Prenatal diagnosis of the Ectrodactyly-Ectodermal dysplasia-clefting (EEC) syndrome has been based upon the detection of ectrodactyly, in association with facial clefting and/or positive family history. Our aim is to describe other ultrasonographic features indicating the presuntive diagnosis, regardless of genetic diagnosis, especially in cases of negative family history. MATERIALS AND METHODS A case report and a review of the literature was assessed. RESULTS Our case report showed a singleton foetus "lobster claw" deformities of hands and feet. Paternal history revealed bilateral agenesia of two fingers. Through literature, 15 case reports of prenatal diagnosis of EEC syndrome were found, 14 of which were eligible for our systematic review. The 33% of cases (5/15) had a familiar history of EEC, thus, we found one case of consanguinity of parents. Anomalies EEC-related were recognized in the 40% of cases (6/15). An association with genitourinary anomalies was found in 30% (5/15) of them. CONCLUSIONS A strong suspicion of final diagnosis of EEC may be done in the presence of ectrodactyly, facial clefting and urinary malformation especially in cases of negative family history. More attention should be given to a genetic counseling, especially to understand a possible relation to other genetic syndromes.

BDNF and NGF Expression in Preneoplastic Cervical Disease According to HIV Status. Int J Mol Sci 2023; 24:10729. [PMID: 37445902 DOI: 10.3390/ijms241310729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 06/18/2023] [Accepted: 06/21/2023] [Indexed: 07/15/2023] Open
Abstract
BACKGROUND Neurotrophins, such as BDNF and NGF, are overexpressed in tumor cells in cervical cancer, and HIV infection is associated with the upregulation of neurotrophin expression. Therefore, we aimed to investigate whether BDNF and NGF are overexpressed in preneoplastic cervical disease from HIV-infected women. METHODS Women with preneoplastic cervical lesions (cervical intraepithelial neoplasia grade 2 or 3) were prospectively enrolled and grouped according to their HIV status. Samples from Loop Electrosurgical Excision Procedure (LEEP) for suspected cervical cancer were obtained, and immunohistochemistry was performed to evaluate BDNF and NGF expression. RESULTS We included in our analysis 12 HIV-infected patients who were matched with 23 HIV-negative patients as a control group. Immunohistochemistry analysis showed that BDNF expression was significantly higher in cervical preneoplastic lesions from HIV-positive women than in the lesions from the control group. In particular, BDNF was expressed in 8/12 HIV-positive patients and 7/23 HIV-negative patients (66.7% vs. 30.4%, χ2 = 4.227; p = 0.040). NGF expression was not significantly higher in cervical preneoplastic lesions from HIV-positive women compared with that in the lesions from the control group. In particular, NGF was expressed in 8/12 HIV-positive patients and in 12/23 HIV-negative patients (66.7% vs. 52.2% χ2 = 0.676; p = 0.411). Logistic regression analysis showed that the HIV status is an independent predictor of BDNF expression in pre-invasive preneoplastic cervical disease when considered alone (crude OR 4.6, 95% CI 0.027-20.347; p = 0.046) and when analyzed with other co-factors (adjusted OR 6.786, 95% CI 1.084-42.476; p = 0.041). CONCLUSIONS In preneoplastic cervical disease, BDNF expression is higher in HIV-infected women than in non-infected controls, and this is independent of the clinical features of the patients and from the presence of the HPV-HR genotype. BDNF can play a key role as a link between the pathways by which HIV and HPV interact to accelerate cervical cancer progression and invasion. These data can be useful to better understand the role of neurotrophins in the cancerogenesis of cervical cancer and the possible therapeutic strategies to improve disease outcomes.

Abstract
Corded and hyalinized endometrioid carcinoma (CHEC) represents a potential pitfall for pathologists. This study aimed to provide a complete overview of all clinicopathological and molecular features of CHEC. Electronic databases were searched for all published series of CHEC. Clinical, histological, immunohistochemical and molecular data about CHEC were extracted and pooled. Six studies with 62 patients were identified; mean age was 49.8 years (range 19-83). Most cases showed FIGO stage I (68%), low grade (87.5%), and a favorable outcome (78.4%), with "no specific molecular profile" (NSMP). A subset of cases showed high-grade features (12.5%), p53 abnormalities (11.1%) or mismatch repair (MMR) deficiency (20%) and occurred at an older age (mean age>60 years). Common features of CHEC were: superficial localization of the corded component (88.6%), squamous/morular differentiation (82.5%), nuclear β-catenin accumulation (92%), partial/total loss of CKAE1/AE3 (88.9%), estrogen receptor (95.7%) and e-cadherin (100%), stromal changes such as myxoid (38.5%), osteoid (24%) and chondroid (4.5%), CTNNB1 mutations (57.9%), and POLE-wild-type (100%); 24.4% of cases showed lymphovascular space invasion. A minority of cases (16.2%) showed poor outcome despite a low-grade, NSMP phenotype; the molecular basis for the aggressiveness of these cases is still undefined. Further studies are necessary in this field.

Abstract
INTRODUCTION HIK1083 and MUC6 have been used as immunohistochemical markers to differentiate gastric-type adenocarcinoma (GTAC) from other endocervical adenocarcinomas. We aimed to assess their diagnostic accuracy through a systematic review and meta-analysis. METHODS Three electronic databases were searched from their inception to July 2022 for all studies assessing the expression in endocervical GTAC vs other endocervical adenocarcinomas. Diagnostic accuracy was assessed as sensitivity, specificity, positive likelihood ratio (LR+), negative likelihood ratio (LR-), diagnostic odds ratio (DOR), and area under the curve (AUC) on SROC curves. RESULTS Four studies with 343 patients were included. HIK1083 showed sensitivity= 0.64, specificity= 0.94, LR+ =8.30, LR-= 0.38, DOR= 33.36, AUC= 89.9%. MUC6 showed sensitivity= 0.51, specificity= 0.74, LR+ =1.96, LR-= 0.71, DOR= 3.48, AUC= 72.8%. CONCLUSION HIK1083 showed high specificity and low sensitivity as a marker of GTAC, with moderate overall accuracy; MUC6 showed moderate specificity and low sensitivity, with low overall accuracy.

Abstract
Pilomatrix-like high-grade endometrioid carcinoma (PiMHEC) has recently been described as an aggressive variant of endometrial carcinoma. Herein, we described a case of ovarian PiMHEC, comparing it to endometrial PiMHEC and assessing previously published cases of putative ovarian PiMHEC. A 65-year-old woman underwent hysterectomy for an ovarian tumor characterized by solid nests of basaloid cells with prominent ghost cell keratinization. Immunohistochemistry showed nuclear β-catenin and CDX2 expression and loss of estrogen and progesterone receptors and PAX8. These features were consistently observed in all previously published cases and may represent diagnostic criteria of PiMHEC. Other frequent features were geographic necrosis and a low-grade endometrioid component. CK7, neuroendocrine, and basal/squamous markers were inconsistently expressed. All cases with available follow-up showed poor prognosis. PiMHEC should be distinguished from mimickers, such as high-grade endometrioid carcinoma with geographic necrosis, low-grade endometrioid carcinoma with ghost cell keratinization, and undifferentiated/dedifferentiated carcinoma. In conclusion, PiMHEC can also occur in the ovary and shows several consistent clinical, morphological, and immunophenotypical features. These features support that PiMHEC is a distinct entity requiring an aggressive management.

Abstract
Abstract
Background
Post COVID–19 syndrome is characterized by chronic fatigue, shortness of breath, dry cough, headache, cognitive difficulties. The complexity of the clinical feature can be explained by a pre–existing endothelial dysfunction (particularly in the patient with high cardiovascular risk) exacerbated and/or linked to viral infection. In the cardiorespiratory rehabilitation program (RCR), the introduction of nutritional supports, vitamins and aminoacids, can be considered a useful approach to post–Covid syndrome. There are observations of positive results with the use of association of oral L–arginine + liposomal vitamin C (Bioarginina®C, 1.66g 2 bottles / day).
Aim of the Study
to evaluate the effects of the use of combination of oral L–arginine + liposomal vitamin C (Bioarginina®C, 1.66g 2 bottles/day) on the functional capacity measured with the six minute walking test (6MWT) of subjects during RCR post COVID 19.
Methods
50 patients with high cardiovascular risk (38 M and 12 F), with mean age 58 ± 7 years, (Group A) undergoing integration with two bottles of L arginine and liposomal vitamin C were examined above for 90 days during the RCR cycle. These had been positive to molecular COVID–19 nasopharyngeal swab test for a period ranging from 15 to 30 days. As a control population, the results obtained with standard treatment in 30 patients with high cardiovascular risk (17 M and 13 F) (mean age 61 ± 8 years) (Group B) after RCR post COVID 19 infection, were examined. The ability to perform normal daily activities was analyzed with the six minute walk test (6MWT) which measures the distance that a subject can run on a flat surface, walking as fast as possible in six minutes, including any interruptions that patient deems necessary. The statistical analysis was performed with the Student‘s T test for paired data. A value of p < 0.05 was considered statistical significant.
Results
At 3 months, improvement in 6MWT values was observed in both groups in Group A: 289 ± 96 m vs 419 ± 105 m (p < 0.0001) – Group B: 280 ± 88 m vs 332 ± 98 m (p < 0.021). However in Group A, these was more significant.
Conclusions
Our data confirm the improvement in the physical performance of post COVID 19 patients with introduction of nutritional supports with L–arginine and liposomal vitamin C.

Abstract
Abstract
Background
Long term dual antiplatelet therapy (LTDAPT) with ticagrelor 60 mg and low–dose aspirin are indicated after acute coronary syndrome (ACS) for the secondary prevention of atherothrombotic events in high–risk patients with a history of ACS of at least 1 year. LTDAPT had a well tolerability and safety profile, but the risk of TIMI major bleeding was increased. However even non significant bleeding may be important because have an effect on quality of life and therefore may lead to treatment discontinuation. Objective To understand the experiences of patients with LTDAPT and nuisance bleeding, and their impact on medication adherence.
Methods
We retrospectively reviewed 225 patients in follow up after ACS with at least one high risk condition (Fig. 1), treated with ticagrelor 60 mg twice daily (after 90 mg twice daily for 12 months). The outpatient follow–up program after hospitalization provides a visits at day 30 after discharge and subsequently after 3 months, then continuing with six–monthly checks. The intensity of bleeding was assessed according to the TIMI score. Any overt bleeding event that did not meet the criteria of major and minor was defined “minimal”.
Results
they are shown in Fig. 2. Minmal bleedings were present in 49 patients (21%), but were not a cause for discontinuation of therapy. However 39 (79%) subjects had asked opinion on stop the therapy at the telephone consultation. We found that: (1) participants adhered to treatment when they believed long term DAPT was important to health outcomes; (2) those who experienced nuisance bleeding reported symptoms to be mild and manageable; (3) participants’ and their family’s understanding of LTDAPT risks and benefits, and their ability to manage symptoms, influenced medication adherence. Factors influencing long term DAPT knowledge included access to medication counselling, engaging with information communicated during medication counselling, and access to timely, relevant and expert information and advice after discharge from hospital.
Conclusions
All adverse events judged to be “not serious” in trials may have an effect on quality of life and therefore may lead to treatment discontinuation. The need to educate the patient in order to improve adherence should therefore be emphasized. The authors underline the importance of careful outpatient follow–up and constant counselling in order to check out compliance and possible adverse effect of long term DAPT risks treatment.

Abstract
Wharton's jelly mesenchymal stem cells (WJ-MSCs) are a class of stem cells with high differentiative potential, an immuno-privileged status and easy access for collection, which raise no legal or ethical issues. WJ-MSCs exhibit several features of embryonic stem cells, both in the phenotypic and genetic aspects, with only a few differences, such as a shorter doubling time and a more extensive ex vivo expansion capacity. WJ-MSCs have immunomodulatory properties, involving both innate and adaptive immune responses. This review focuses on the role of WJ-MSCs in the management of graft-versus-host disease (GvHD), a life-threatening complication of the allogenic transplantation of hematopoietic stem cells. Different studies documented the beneficial effect of the infusion of WJ-MSCs, even when not fully HLA identical, in patients with severe GvHD, refractory to standard treatment. Finally, we summarized current ongoing clinical trials with WJ-MSCs and their potential in regenerative medicine.
