Alteration of BRCA-1 tumor suppressor gene expression in serous and mucinous ovarian neoplasms in the benign-borderline-malignant pathway

Advances in understanding the molecular mechanisms of borderline ovarian tumors

Borderline ovarian tumors (BOTs), which are a special type of epithelial tumor of the ovary, lie between benign and malignant tumors and have low malignant potential. Due to the fact that the early symptoms of these tumors are relatively subtle, they are not easy to diagnose clinically. This study explores advancements in clinical detection methods and provides a comprehensive overview of molecules such as cell migration factors, cell transcription factors, cell damage repair factors, cell cycle regulators, and tumor suppressor genes that are related to the development of BOTs and their related mechanisms in recent years, thus aiming to provide more sensitive, specific, and efficient differential diagnosis and treatment plans for patients to improve their prognosis and survival outcomes.

Clinical study on laparoscopic minimally invasive surgery and transumbilical single-port laparoscopic surgery in the treatment of benign ovarian tumours and its influence on ovarian functions

OBJECTIVE

The objective of this study was to explore the influence of traditional laparoscopic surgery and transumbilical single-port laparoscopic surgery on ovarian function in patients with benign ovarian tumours.

MATERIALS AND METHODS

Forty-four patients with benign ovarian tumours who were treated in our hospital from January 2020 to June 2021 were selected and randomly divided into two groups, with 22 cases in each group according to random number table. The conventional group was treated with conventional laparoscopic surgery, while the modified group was treated with transumbilical single-port laparoscopic surgery. The measurement method was t -test, and the enumeration method was two tests. The clinical operation-related indicators, ovarian function (follicle-stimulating hormone, E 2 and luteinising hormone), complication incidence, Visual Analogue Scale (VAS) and landscaping satisfaction scores of the two groups were compared.

RESULTS

There were no significant differences in complications and operation duration between the two groups ( P > 0.05). After treatment, the ovarian function indexes and beautification satisfaction scores of the modified group were significantly superior to those of the conventional group ( P < 0.05). Besides, the intraoperative bleeding volume, post-operative exhaust time, hospital stay and three-dimensional VAS scores on day 1 and day 3 after surgery of the modified group were lower than those of the conventional group ( P < 0.05).

CONCLUSION

Transumbilical single-port laparoscopic surgery for benign ovarian tumours has a significant clinical effect, which can effectively reduce bleeding during the operation, improve ovarian function, relieve surgical pain, promote rapid post-operative recovery and improve patients' satisfaction with landscaping. It is worthy of clinical application.

The Many Faces of Serous Neoplasms and Related Lesions of the Female Pelvis: A Review

Ovarian serous tumors and related lesions are one of the most common conditions of the female genital tract. While ovarian high-grade serous carcinoma carries high mortality and adverse prognosis, most other serous lesions have better clinical behavior. In recent years, significant progress has been made in understanding the nature and histogenesis of these lesions that has contributed to better and more precise clinical management. Most of the high-grade serous carcinomas involve the ovaries and/or peritoneum, although in most cases, their origin seems to be in the fallopian tube. This view is supported by the recognition of precursor lesions in the fallopian tube, such as p53 signature and serous tubular in situ carcinoma. This paper presents salient morphologic, immunohistochemical, and molecular data related to serous tumors and related lesions of the female pelvis and discusses the histogenetic interrelationship among these lesions in light of current knowledge.
