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.

Transvaginal Ultrasound vs. Magnetic Resonance Imaging: What Is the Optimal Imaging Modality for the Diagnosis of Endometriosis?

Endometriosis, an intriguing gynecological illness, poses a substantial health concern for women of reproductive age, despite its widespread occurrence and limited comprehension. The objective of this study is to assess the diagnostic precision of transvaginal sonography (TVS) and pelvic magnetic resonance imaging (MRI) for the identification of deep infiltrated endometriosis (DIE). This study encompassed a cohort of 256 patients exhibiting signs and symptoms of endometriosis, with the aim of assessing the diagnostic accuracy over a span of four years. Both TVS and pelvic MRI were employed in the same centers to analyze each subject. The histopathologic analysis and laparoscopy were the most reliable and widely accepted methods for evaluation. TVS is a reliable diagnostic tool for ovarian endometriomas, obviating the necessity for MRI confirmation. The specificity of TVS in diagnosing ovarian endometriomas is 57.14%, while its sensitivity is 93.78%, resulting in an overall accuracy of 84.47%. In relation to parametrial lesions, the sensitivity, specificity, and accuracy of TVS and MRI were as follows: TVS: 9%, 97%, 32%, MRI: 27.14%, 89.19%, and 40.11%. Concerning the uterosacral lesions, the sensitivity, specificity, and accuracy of TVS and MRI were as follows: TVS:14.63%, 94.74%, and 55%, while MRI: 65.88%, 66.30%, and 66.1%. Regarding rectal endometriosis, the sensitivity, specificity, and accuracy of TVS and MRI were as follows: 69.72%, 76.87%, and 73.82% for TVS, and 66.28%, 94.51%, and 80.79% for MRI. The results of the present study indicate that whereas MRI generally exhibits superior capability in assessing the severity of endometriosis, TVS demonstrates sufficient diagnostic accuracy in DIE comparable to MRI.

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.

Transvaginal Ultrasound vs. Magnetic Resonance Imaging (MRI) Value in Endometriosis Diagnosis.

(1) Background: Endometriosis is a widespread gynecological condition that causes chronic pelvic discomfort, dysmenorrhea, infertility, and impaired quality of life in women of reproductive age. Clinical examination, transvaginal ultrasonography (TVS), and magnetic resonance imaging (MRI) are significant preoperative non-invasive diagnosis procedures for the accurate assessment of endometriosis. Although TVS is used as the primary line for diagnosis, MRI is commonly utilized to achieve a better anatomical overview of the entire pelvic organs. The aim of this systematic review article is to thoroughly summarize the research on various endometriosis diagnosis methods that are less invasive. (2) Methods: To find relevant studies, we examined electronic databases, such as MEDLINE/PubMed, Cochrane, and Google Scholar, choosing 70 papers as references. (3) Results: The findings indicate that various approaches can contribute to diagnosis in different ways, depending on the type of endometriosis. For patients suspected of having deep pelvic endometriosis, transvaginal sonography should be the first line of diagnosis. Endometriosis cysts are better diagnosed with TVS, whereas torus, uterosacral ligaments, intestine, and bladder endometriosis lesions are best diagnosed using MRI. When it comes to detecting intestine or rectal nodules, as well as rectovaginal septum nodules, MRI should be the imaging tool of choice. (4) Conclusions: When diagnosing DE (deep infiltrative endometriosis), the examiner's experience is the most important criterion to consider. In the diagnosis of endometriosis, expert-guided TVS is more accurate than routine pelvic ultrasound, especially in the deep infiltrative form. For optimal treatment and surgical planning, accurate preoperative deep infiltrative endometriosis diagnosis is essential, especially because it requires a multidisciplinary approach.
