Endometrioid Borderline Ovarian Tumor: Clinical Characteristics, Prognosis, and Managements.

BACKGROUND: Endometrioid borderline ovarian tumor (EBOT) is a rare subtype of borderline ovarian malignancies. This study was designed to determine the prognosis of a series of EBOT. METHODS: This is a retrospective review of patients with EBOT treated in or referred to our institutions and a centralized, histological review by a reference pathologist. Data on the clinical characteristics, management (surgical and medical), and oncologic outcomes of patients were required for inclusion. RESULTS: Forty-eight patients were identified. Median age was 52 years (range 14-89). Fourteen patients underwent a conservative surgery and 32 a bilateral salpingo-oophorectomy (unknown in 2 cases). Two patients had bilateral tumors. Forty-three patients had stage I disease, and five patients had stage II disease (10%). Stromal microinvasion and intraepithelial carcinoma was observed in 6 (12%) and 13 (27%) patients respectively. Endometriosis was histologically associated in 12 patients (25%). Synchronous endometrial disease was found in 7 (24%) of 29 patients with endometrial histological evaluation. The median follow-up was 72 months (range 6-146). Two patients developed a recurrence after cystectomy in form of borderline disease (5%). No death related to EBOT occurred. CONCLUSIONS: Peritoneal restaging surgery should be performed if not realized initially, because 5% of EBOTS are diagnosed at stage II-III. Fertility-sparing surgery seems a safe option in selected patients. Because synchronous endometrial diseases, including endometrial carcinoma are frequent, systematic hysterectomy (or endometrial sampling in case of fertility-sparing surgery) is mandatory. Prognosis is generally excellent. Recurrence is a rare event (6%), but it can occur in the form of invasive disease.

Clear Cell Borderline Ovarian Tumor: Clinical Characteristics, Prognosis, and Management.

BACKGROUND: Clear cell borderline ovarian tumor (CCBOT) is one of the rarest subtypes of borderline ovarian malignancies. The aim of this study was to determine the prognosis of a series of CCBOT. PATIENTS AND METHODS: A retrospective review of patients with CCBOT treated or referred to our institutions. A centralized histological review by a reference pathologist and data on the clinical characteristics, management, and outcomes of patients were required for inclusion. RESULTS: Nineteen patients were identified. Median age was 62 (range 36-83) years. Four patients underwent a conservative surgery and 14 a bilateral salpingo-oophorectomy +/- hysterectomy (unknown in 1 case). One patient had bilateral tumor, and all cases were stage-I disease. All CCBOTs showed an adenofibromatous pattern. Stromal microinvasion was observed in seven cases and intraepithelial carcinoma in two cases. Endometriosis was histologically associated in one case. The median follow-up was 76 (range 6-231) months. No recurrence occurred. Two patients died of intercurrent disease. CONCLUSIONS: Peritoneal staging procedures should always be associated, but restaging surgery could be omitted if there was no suspicious lesion in the peritoneum during initial surgery, since all patients reported had stage-I disease. Fertility-sparing surgery appears to be a safe alternative in young patients. Synchronous endometrial disorders with atypia are infrequent. Prognosis is generally excellent, and long-term risk of recurrence is low. The two recurrences described in literature occurred in stage-IC diseases, highlighting the importance of avoiding perioperative rupture.

Brenner Borderline Ovarian Tumor: A Case Series and Literature Review.

BACKGROUND: Most frequent borderline ovarian tumors are serous and mucinous subtypes. Less frequent borderline diseases are endometrioid, clear-cell, and Brenner tumors (BBOT). Very little is known about the latter subtype, and most studies include very short series or case reports. The aim of this study is to determine the prognosis of a continuous series of BBOT and analyze data published in the literature on this rare entity. PATIENTS AND METHODS: A retrospective review of patients with BBOT treated or referred to our institutions was conducted. A centralized histological review by a reference pathologist and data on the clinical characteristics, management, and outcomes of patients were required for inclusion. RESULTS: Overall, 17 patients were identified. Median age was 62 (range 42-85) years. Six patients underwent unilateral salpingo-oophorectomy, and 11 bilateral salpingo-oophorectomy +/- hysterectomy and/or staging surgery. In total, 16 patients had unilateral tumor, and all patients had stage I disease. Stromal microinvasion was observed in three cases. Median follow-up was 60 months (range 7-118 months). One patient developed a recurrence in contralateral ovary after unilateral salpingo-oophorectomy. One patient had previous history of urothelial tumor. CONCLUSIONS: Peritoneal staging surgery is not required because all patients reported had stage I disease. One recurrence occurred. When reviewing all the 82 cases reported in the literature (including ours), 9% had previous history or synchronous urothelial tumor, suggesting the need to carefully check for urological disease in patients with BBOT.

Posterior pelvic exenteration and retrograde total hysterectomy in patients with locally advanced ovarian cancer: Clinical and functional outcome.

OBJECTIVE: To evaluate clinical outcomes and postoperative quality of life in patients affected by locally advanced ovarian cancer who underwent pelvic posterior exenteration with Hudson-Delle Piane radical retrograde hysterectomy. MATERIALS AND METHODS: Our study was done on a retrospective cohort using data from 22 patients who underwent surgery between 2010 and 2014 at the Gynecological Oncologic Center of Parma, Parma, Italy. RESULTS: Residual disease after surgery (Sugarbacker index) was absent (CC-0) in 68% of cases. Tumor size was < 2.5 mm (CC-1) in 14% of cases and between 2.5 mm and 2.5 cm (CC-2) in 18% of cases. Complications during surgical procedure occurred in 64% of patients (14/22), but without severe consequences. Immediate postoperative complications (≤ 30 days) occurred in 82% of patients (18/22), and delayed complications (> 30 days) occurred in 23% (5/22) of patients. No patient died because of a complication. Urinary and rectal incontinence occurred in 5% and 16% of patients, respectively. Disease recurrence occurred in 58% of patients, median disease-free survival was 14 months (range, 6-36 months), and median overall survival was 21 months (range, 6-42 months). CONCLUSION: Our study confirmed that pelvic posterior exenteration associated with retrograde radical hysterectomy represents the safest radical surgical approach to advanced ovarian cancer, which permits preservation of the pelvic autonomic nerve plexus and, therefore, bladder and colorectal functions.
