Endometrioid adenocarcinoma of the rectovaginal septum: A case report / 中南大学学报(医学版)

Primary endometrioid adenocarcinoma of the rectovaginal septum is rare. Its pathogenesis is not clear and there is no standard treatment. One patient with endometrioid adenocarcinoma of the rectovaginal septum arising from deep infiltrative endometriosis was admitted to Qingdao Municipal Hospital. The patient presented with incessant menstruation and abdominal distension. She had bilateral ovarian endometriotic cystectomy 6 years ago. Imaging findings suggested a pelvic mass which might invade the rectovaginal septum. Pathological results of primary surgery confirmed endometrioid carcinoma of the pelvic mass arising from the rectovaginal septum. Then she had a comprehensive staged surgery. Postoperative chemotherapy was given 6 times. No recurrence or metastasis was found during the 2-year follow-up. The possibility of deep infiltrating endometriosis and its malignant transformation should be considered in the differential diagnosis of a new extragonadal pelvic lesion in a patient with a history of endometriosis, which would avoid misdiagnosis and missed diagnosis.

Research progress of circulating tumor DNA in ovrian cancer / 国际肿瘤学杂志

With the continued development of molecular biology technologies,circulating tumor DNA (ctDNA)has shown certain value in the diagnosis and treatment of malignant tumors. The emergence of next generation sequencing technology makes ctDNA detection more accurate and rapid. ctDNA plays a certain role in the early diagnosis,disease monitoring,therapeutic evaluation and medication guide of ovarian cancer by vir-tue of its safety and non-invasiveness. The application of ctDNA detection is insufficient at present,but with the continuous development of sequencing technology,ctDNA will play increasingly important roles in the diagno-sis,personalized treatment and prognosis evaluation of ovarian cancer.
