Endometrial carcinoma is a prevalent gynecological malignancy characterized by its origin in the endometrium, the lining of the uterus. Early-stage endometrial carcinoma, often confined to the uterus, presents a unique set of features and challenges that, if promptly identified and treated, can significantly improve patient outcomes. This article reviews the clinical, histopathological and molecular features of early-stage endometrial carcinoma, alongside the current approaches for diagnosis, management, and prognosis. Emphasis is placed on the importance of recognizing symptomatic presentations, the role of imaging and biopsy in diagnosis, and the potential of molecular profiling for personalized treatment strategies [1].

Endometrial carcinoma is the most common type of uterine cancer, primarily affecting postmenopausal women, although it can occur at any age. It typically arises from the endometrial lining of the uterus and is categorized into two main types based on its pathology: Type I (estrogen-dependent) and Type II (non-estrogen dependent), with Type I being more common in early-stage disease [2]. The early detection of endometrial carcinoma is crucial for effective treatment and favorable prognosis, making it imperative to understand its early-stage features.

Clinical features

The early stages of endometrial carcinoma often present with specific clinical features that prompt further investigation. The most common symptom is abnormal uterine bleeding, particularly in postmenopausal women. Other symptoms may include pelvic pain, pain during intercourse, and unexplained weight loss, although these are less specific and can be associated with other conditions. The presence of these symptoms necessitates a thorough gynecological evaluation, including a pelvic examination and endometrial biopsy [3].

Histopathological features

Histopathologically, early-stage endometrial carcinoma is predominantly of the endometrioid type, characterized by glandular differentiation that resembles the normal endometrial glands. The grade of the tumor, determined by the degree of differentiation, is a critical factor in prognosis. Lower grade tumors have cells that look more like normal cells and tend to have a better prognosis than higher grade tumors, where cells appear more abnormal and tend to grow and spread more quickly.

Molecular features

Recent advancements have highlighted the importance of molecular features in endometrial carcinoma. The most common genetic alterations include mutations in the PTEN, PIK3CA, KRAS, and ARID1A genes, among others. Additionally, microsatellite instability (MSI) and mismatch repair (MMR) deficiencies are prominent in a subset of these cancers, offering potential targets for immunotherapy [4]. Molecular profiling of early-stage endometrial carcinoma can guide personalized treatment approaches, improving outcomes.

Diagnosis and management

Diagnosis of early-stage endometrial carcinoma typically involves transvaginal ultrasound (TVUS) to assess the endometrial thickness and identify any abnormalities, followed by an endometrial biopsy for histopathological examination. Once diagnosed, the standard treatment for early-stage disease is surgical, involving a total hysterectomy with bilateral salpingo-oophorectomy. Depending on the tumor grade and stage, adjuvant therapy such as radiation or chemotherapy may be recommended [5].

Description

The early detection and treatment of endometrial carcinoma are paramount for favorable patient outcomes. Understanding the clinical, histopathological, and molecular features of early-stage disease is essential for clinicians to make informed decisions regarding diagnosis and management. Moreover, the potential for personalized treatment based on molecular profiling represents a significant advancement in the care of patients with this condition.

Early-stage endometrial carcinoma, while presenting challenges, also offers opportunities for effective treatment and excellent prognosis. The key to improving outcomes lies in the early detection through the recognition of symptomatic presentations and the use of advanced diagnostic and molecular profiling techniques [6]. As research progresses, it is anticipated that further insights into the molecular underpinnings of this disease will lead to even more targeted and effective treatments, enhancing the quality of life and survival rates for affected individuals.

Endometrial carcinoma stands as a prevalent malignancy affecting women worldwide, with its incidence steadily rising over recent decades. Emerging primarily from the endometrium, the inner lining of the uterus, endometrial carcinoma comprises a diverse spectrum of histopathological subtypes, each bearing distinct clinical behaviors and prognoses. Early-stage endometrial carcinoma, often confined to the uterus, poses a unique set of challenges and opportunities in clinical management [7].

The rise in the incidence of endometrial carcinoma parallels the increasing prevalence of risk factors such as obesity, hormonal imbalances, nulliparity and a history of endometrial hyperplasia. While postmenopausal women constitute the majority of cases, a concerning trend in recent years involves a rising incidence among younger women, highlighting the importance of heightened vigilance across age groups.

Conclusion

The clinical presentation of early-stage endometrial carcinoma frequently manifests as abnormal uterine bleeding, heralding its detection in many cases. However, the heterogeneity of clinical symptoms underscores the necessity of a comprehensive diagnostic approach, encompassing imaging modalities, histopathological evaluation and molecular profiling. In this review, we delve into the intricate landscape of early-stage endometrial carcinoma, exploring its clinical, histopathological and molecular features. Through an understanding of its diverse manifestations and underlying molecular alterations, clinicians can navigate the diagnostic and therapeutic challenges posed by this malignancy, ultimately striving toward improved patient outcomes and enhanced quality of life.
