Prognostic implications of immunohistochemistry in patients with endometrial cancer.

Various histological cell types, high histological grade, extensive myometrial invasion, and the presence of lymphovascular involvement are recognized as risk factors for disease development. Individuals carrying mutations in MutL homolog 1 (MLH1), MutS homolog 2 (MSH2), MutS homolog 6 (MSH6), or postmeiotic segregation increased 2 (PMS2) genes face an increased susceptibility to both endometrial and colorectal malignancies, with a lifetime risk ranging from 40% to 60%. This research aimed to investigate the prevalence of specific immunohistochemical (IHC) markers and microsatellite instability in endometrial carcinomas and explore potential associations with patient characteristics and clinical outcomes. Out of 58 patients with comprehensive follow-up data, a subgroup of 21 cases underwent rigorous IHC evaluation, involving estrogen receptor (ER), progesterone receptor (PR), Ki67, MLH1, MSH2, MSH6, PMS2, and p53 markers. Statistical analysis, employing the χ² (chi-squared) test, was conducted to assess the connection between individual IHC markers and clinical outcomes, with particular emphasis on the influence of radiation, chemotherapy, or brachytherapy treatment, as well as the occurrence of recurrence or mortality. Notably, significant correlations were observed in cases where MSH2 and MSH6 exhibited positive results, indicating their association with the use of chemotherapy and brachytherapy. However, the analysis pertaining to International Federation of Gynecology and Obstetrics (FIGO) stage or tumor grade did not reveal any statistically significant relationships with these parameters.

Robotic Surgery a Step Forward in Standardization of Hysterectomy in Patients with Deep Infiltrating Endometriosis.

Introduction: Hysterectomy in cases with deep infiltrating endometriosis (DIE) poses a particular challenge represented by the lack of standardization, causing technical difficulties or incomplete resection of the deep endometriosis lesions. AIM: This article attempts to use the concept of lateral and antero-posterior virtual compartments in the standardization of robotic hysterectomy (RH) in cases of deep parametrial lesions according to ENZIAN classification. MATERIAL AND METHOD: We collected data from 81 patients who underwent total hysterectomy and en bloc excision of the endometriotic lesions by robotic surgery. Results: Excision was realized by the technique of retroperitoneal hysterectomy, its standardization depending on the ENZIAN classification being described step by step. Tailored robotic hysterectomy always included the en-block removal of uterus, adnexa, and posterior and anterior parametria, which included endometriotic lesions and the upper one-third of the vagina with all endometriotic lesions of posterior and lateral vaginal mucosa. Discussion: The hysterectomy and parametrial dissection must be done according to the size and location of the endometriotic nodule. The goal of hysterectomy for DIE is to release the uterus and the endometriotic tissue without risks of complication. CONCLUSION: "En-bloc" hysterectomy together with endometriotic nodules, where the parametrial resection is tailored according to the lesions, is an optimum method, because the blood loss, operative time, and intraoperative complications are reduced comparing with other methods.

Diagnosis of endometriotic lesions by sonovaginography with ultrasound gel.

AIMS: The aim of the study was to evaluate the diagnostic ability of sonovaginography (SVG) with ultrasound gel in patients with endometriosis. MATERIAL AND METHODS: We conducted a multicentre prospective study, which included 193 patients with symptoms highly suggestive for endometriosis. All patients were investigated by transvaginal sonography and SVG with gel and afterwards underwent laparoscopic surgery. For each category of endometriotic lesions investigated, we calculated and compared the sensitivity, specificity,  positive predictive value and negative predictive value of the imagisticinvestigations used. RESULTS: In the case of endometriotic lesions of the uterosacral ligaments, SVG with gel had a sensitivity of 78.5% and a specificity of 96% (p=ns). The lesions of the vagina and rectovaginal septum were diagnosed with a sensitivity of 79%, respectively 94% (p=ns), obtaining a specificity of 99%, respectively of 97% (p=0.007). The lesions of the Douglas pouch were identified with a sensitivity of 81% (p=0.015), and those of the rectosigmoid with a 94% sensitivity (p=0.010). We obtained lower sensitivity (67%) in detecting the lesions of the urinary bladder (p=ns). CONCLUSIONS: SGV with ultrasound gel represents a useful investigation tool for the evaluation of endometriotic lesions in the posterior pelvic compartment.

Perineal reconstruction with biologic graft vulvoplasty for verrucous carcinoma treated by repeated vulvar excisions: a case report.

Vulvar neoplasia represents 5% of malignancies in female genital tract and 0.6% of all cancers in women. Although it is known to be a rare type of cancer, which occurs especially in elderly women, its incidence is increasing in young females because of its association with the human papillomavirus (HPV). In this paper, we report the case of a 46-year-old woman, gravidity 4, parity 3, with a medical history of multiple vulvar excisions for recurrent ulcerative vulvar lesions during a period of 11 years. The first lesion appeared in 2003, it was excised and the histopathological result showed squamous cell carcinoma with undifferentiated areas and chronic ulcerative inflammation. The patient underwent radiation therapy remaining at the end of it a small-ulcerated lesion at the superior vulvar commissure, which was biopsied in 2004 showing chronic ulcerative inflammation with reparatory areas of squamous immature benign metaplasia In April 2014, a dermatological consult described vulvar scleroatrophic lichen confirmed by a biopsy. In November 2014, the patient presented to our clinic when a vicious vulvar scar was detected, with a transformed tegument with aspect of atrophic lichen. A perineal reconstruction including anal sphincter plasty was performed. Due to the important remaining skin defect, a Surgisis graft vulvoplasty was performed. The histopathological result of the excised suspect areas was vulvar intraepithelial high-grade neoplasia (VIN III). A retrospective histopathological review of the case established that is more accurate to consider that the vulvar lesions were, all along, a very well differentiated squamous cell carcinoma (verrucous carcinoma), which lacks cytopathic effect of HPV infection, has a low p53 expression but a high Ki67. Case evolution was favorable with the acceptance and integration of the biologic grafts at two months after surgery and normal healing.

The assessment of immunohistochemical profile of endometriosis implants, a practical method to appreciate the aggressiveness and recurrence risk of endometriosis.

UNLABELLED: Endometriosis represents a chronic female genital tract disease characterized by implants outside the endometrial cavity, leading to alteration of pelvic anatomy and having as result chronic pelvic pain and infertility. AIM: From the molecular perspective, the aim of studying endometriosis is identifying a cause and a consequence, that lead to the appearance and perpetual arising of new implants. The description of the immunohistochemical (IHC) profile of ectopic endometrium could represent a new element in the pathogenesis of endometriosis and also a practical method to appreciate the aggressiveness and possibility of recurrence of the disease. The study consisting of histopathological and immunohistochemical (IHC) analysis of the tissues excised included 14 patients, operated from June to December 2014, to which was confirmed the presumptive diagnosis of endometriosis, based on anamnesis, clinical examination and ultrasound appearance. We identified the expression of estrogen and progesterone receptors, whose presence in the ectopic endometrium guides the medical hormone postoperative treatment. We also identified the expression of a cellular proliferation marker - Ki-67, and inhibition marker of cellular apoptosis - Bcl-2, in order to characterize the aggressiveness of endometriosis implantations and a stromal marker CD10. Although there are plenty of medical and surgical therapeutic methods available, the treatment of endometriosis must be individualized for every patient taking into consideration the IHC analysis. Consolidation of surgical treatment by prescription of a medical long-term treatment is indispensable, because endometriosis is a chronic relapsing disease.
