ABSTRACT
Objective:To explore the prognosis of epithelial ovarian cancer patients with multiple recurrences (≥2 times) who underwent three times or more cytoreductive surgeries, and to analyze the factors associated with prognosis.Methods:The clinicopathological data and follow-up data of 23 patients with ovarian cancer admitted to the Obstetrics and Gynecology Hospital of Fudan University from January 1, 2015 to January 30, 2022 with three times or more cytoreductive surgeries were collected. The degree of surgical resection, site of recurrence and metastasis, postoperative complications, and prognosis were retrospectively analyzed. The univariate Cox proportional hazards model was performed to identify the variables associated with survival.Results:(1) The median age of 23 patients with multiple recurrent ovarian cancer was 48 years old (44-55 years). Among them, 18 cases underwent tertiary cytoreductive surgery (TCS), 2 cases underwent quaternary cytoreductive surgery, 2 cases underwent quinary cytoreductive surgery, and 1 case underwent senary cytoreductive surgery. Among the 23 patients with multiple recurrent ovarian cancer, 21 cases (91%, 21/23) had serous carcinoma, 16 cases (70%, 16/23) had advanced stage (stage Ⅲ-Ⅳ), and 19 cases (83%, 19/23) had high differentiation. (2) Based on the premise that satisfactory cytoreduction was achieved by primary debulking surgery (PDS) and no visible residual disease (R0) was achieved by secondary cytoreductive surgery (SCS), the maximum diameter of the recurrent tumors was up to 10.0 cm and 62% (20/32) of patients with multiple metastatic sites. The R0 rate for three times or more cytoreductive surgeries (32 times in total) reached 88% (28/32), with a postoperative complication rate of 47% (15/32), and only 3% (1/32) for grade Ⅲ or above. During a median follow-up time of 31.1 months (20.6-43.9 months) after TCS, 20 patients (87%, 20/23) recurred after TCS, and 8 patients (35%, 8/23) eventually died of ovarian cancer. Among them, the three-year postoperative survival rate of 22 patients with R0 was 57.6%, and the patient with residual lesions ≥1 cm died at 9.2 months after TCS. (3) In univariate analysis, ages, the time interval between PDS and SCS >32 months, the interval between SCS and TCS >16 months, and no metastatic peritoneal carcinoma were associated with longer progression free survival after TCS (all P<0.05); while treatment-free interval (TFI) >10 months after SCS, the interval between SCS and TCS >16 months, no ascites and platinum-sensitive status were associated with disease-specific survival after TCS (all P<0.05). Conclusions:It is feasible to perform three times or more cytoreductive surgeries in patients with multiple recurrent ovarian cancer who are expected to achieve R0 and have manageable complications. However, the pros and cons of surgery need to be carefully evaluated for the patients whose ascites are massive and whose previous cytoreduction does not achieve R0. A prolonged TFI and previously longer surgical interval might get potential survival benefits.
ABSTRACT
Objective To investigate clinical significance and application of modified pelvic floor reconstruction developed by Peking Union Medical College Hospital ( MPFR ) in treatment of severe pelvic organ prolapse (POP) by comparing the effectiveness, quality of postoperative sexual life, life satisfaction and risk factors for POP recurrence with the following two surgical procedures: traditional total vaginal hysterectomy with anterior-posterior colporrhaphy (TVH-APC) and total vaginal hysterectomy with lateral colporrhaphy and sacrospinous ligament fixation and vaginal bridge repair and episiotomy (TVH-LC-SSLFVBR-EP). Methods Totally 173 patients with severe POP and at least two compartments defects of pelvic floor underwent surgeries in the study, 86 patients (group A) were treated by MPFR with polypropylene mesh application, 58 (group B) were treated by TVH-APC, and 29 patients (group C) were treated by TVH-LC-SSLF-VBR-EP. Peri-operative data and outcomes of postoperative courses at 6, 12, 18 months were collected and analyzed, in the meantime, the risk factors of recurrence were studied. Results (1) No statistical difference was observed among the above 3 groups in terms of length of operation, amount of blood loss, length of hospital stay, and morbidity after surgery ( P ＞ 0.05). ( 2 ) Cost hospitalization was ( 11 448 ±3049) Yuan in group A, which was significantly higher than (7262 ± 1607) Yuan in group B and (7140 ± 1817 ) Yuan in group C (P ＜ 0.05 ). (3) The length of vaginal cuff of (7.5 ± 1.4) cm in group A and ( 5.6 ± 1.1 ) cm in group C were significantly longer than (7.1±0.6) cm in group B ( P＜0.05). The width of vaginal cuff of (4.3±0.3) cm in group A was larger than (3.4±0.3) cm in group B and (3.3±0.4) cm in group C (P＜0.05). (4) The recurrence rate at 12 months after surgery was 12.8% (11/86)in group A, which was similar with 17.2%(5/29) in group C (P＞0.05) and significantly less than 36.2% (21/58) in group B (P＜0.05). The rate of active sexual life of 16.3% (14/86) in group A was significantly higher than 1.7% (1/58) in group B and 0 in group C ( P ＜ 0. 05 ). The index of life quality improvement at 12 months after surgery was 48±12 in group A, which was no less than 53±16 in group C ( P＞0.05) and higher than 27 ± 9 in group B ( P＜0.05). (5 ) Mesh rejection was observed in 6 patients in group A within 3 months after surgery, while the posterior vaginal wall was exclusively involved. No difference was found in urinary retention or urinary incontinence among three groups (P ＞0. 05 ). (6) The severe degree of POP, type of surgical procedure ( TVT-APC), anterior compartment defect of pelvic floor,and early days of performing pelvic floor reconstruction surgeries were high risk factors for POP recurrence (P＜ 0.05). Conclusions MPFR has a better curative effect and lower recurrence rate on patients with POP. It can help patients regain integrity of anatomical structure and functions of pelvic floor. TVH-LCSSLF-VBR-EP is also effective.
ABSTRACT
Objective To detect CD_(36) expressions in polycystic ovary (PCO), and to explore its correlation with local androgen and insulin at transcription level. Methods From August 2002 to February 2003, 12 patients with asymmetric PCO, 15 primary or secondary infertile patients without endocrine disorders and 8 polycystic ovary syndrome (PCOS) with bilateral PCO were recruited. Extraction of follicular fluid and detection of testosterone(T), dehydroepiandrosterone sulfate (DHEAS), insulin (INS) and androstenedione (A_2) were performed. Relative CD_(36) mRNA expression level of human ovarian inner thecal cells was analyzed by auto image analysis system (IAS) after RT-PCR. Results The level of CD_(36) mRNA expression in thecal cells was 0.24?0.07 in polycystic ovary of PCO group and 0.21?0.05 in bilateral ovaries of PCOS group, respectively, which were significantly lower than 0.83?0.13 in normal ovaries (P
ABSTRACT
The growth and spread of malignant neoplasms largely depend on angiogenesis.Recent studies demonstrate that a various types of neovascularization including angiogenesis,vasculogenesis and vasculogenic mimicry exist in a few highly aggressive tumors.Ovarian carcinoma is the leading cause of death in gynecologic malignancy.Here,we review the effect of angiogenesis,vasculogenesis and vasculogenic mimicry in development and spread of ovarian carcinoma.
