Experience in the Management of Vaginal Cuff Dehiscence and Evisceration: A Retrospective 37-Year Single-Center Study.

Purpose: Vaginal cuff dehiscence (and evisceration) (VCD(E)) is an extremely rare and late-onset complication of total hysterectomy (TH). Limited evidence is available to guide clinicians in managing VCD(E). This study aimed to summarize the clinical characteristics of patients with VCD(E) treated in our center and share our experience in managing VCD(E). Patients and methods: From 1983 to 2020, a total of 14 cases of VCD(E), including 10 cases in our hospital and 4 cases in other hospitals, were included. Medical records were reviewed to summarize the clinical features and management of VCD(E). Results: The incidence of VCD(E) in our hospital was 10/46,993 (0.02%), and all 10 patients underwent laparoscopic hysterectomy. The median TH-to-VCD(E) interval was 3.13 months (8 days-27.43 months), and 11/14 (78.57%) patients experienced VCD(E) after coitus. The 3 major symptoms included abdominal pain in 11 patients, irregular vaginal bleeding in 8, and sensation of bulging or prolapsed organs in 4. Except for 2, most patients presented to our hospital within 72 h since the onset of the discomfort. All 14 cases were diagnosed through speculum examination: 3 had simple VCD, and 11 had VCDE. The protruding bowels of 4 patients were immediately manually repositioned in the emergency department without anesthesia. Regarding the surgical approach, 11 patients underwent simple transvaginal, 2 patients underwent laparoscopic-vaginal combined (transvaginal cuff closures), and 1 patient underwent laparoscopic. All but 1 patient did not undergo resection of the eviscerated organs. The median follow-up period was 39.33 (7.9-159.33) months. No patients showed any evidence of recurrence to date. Conclusions: Laparoscopic hysterectomy is a risk factor for VCD(E), and early initiation of sexual intercourse is the most common trigger of VCD(E). Clinicians should educate patients to postpone sexual intercourse for at least 3-6 months after TH. Immediate medical attention and patient-specific surgical management are crucial to avoid serious complications.

Case Report: Management of Recurrent Ovarian Squamous Cell Carcinoma With PD-1 Inhibitor.

Malignant transformations, such as ovarian squamous cell carcinoma (SCC) in ovarian mature cystic teratoma (OMCT), are rare tumors. The management of recurrent disease is still a challenge, and the gene mutations involved remain unclear. We herein report a recurrent case of ovarian SCC with a PIK3CA gene variation and immunohistochemical staining of programmed death-ligand 1 (PD-L1) >10%. This patient achieved clinical remission after platinum-based effective chemotherapy and programmed death 1 (PD-1) immunotherapy.

[Clinical Characterization of Patients with Ovarian Mass Combined with Dysplasia of Secondary Sexual Characteristics].

Objective To investigate the clinical characteristics of preadolescent and adolescent female patients with ovarian mass combined with dysplasia of secondary sexual characteristics. Methods This study retrospectively analyzed 18 cases of ovarian mass combined with dysplasia of secondary sexual characteristics aged 0-19 years admitted to Peking Union Medical College Hospital from January 2012 to November 2019.By analyzing the clinical manifestations,surgical methods,postoperative pathology,therapies and prognosis of the cases,we summarized the diagnosis and treatment ideas. Results Among the 18 cases,7(7/18,38.9%)developed secondary sex signs before puberty,including 5 cases showing precocity(including 2 cases of juvenile granulosa cell tumor,1 case of gonadoblastoma,1 case of ovarian follicular cyst,and 1 case of 46,XY simple gonadal dysplasia combined with dysgerminoma)and 2 cases presenting masculine manifestations(1 case of steroid cell tumor and 1 case of sclerosing stromal tumor).The rest 11(11/18,61.1%)cases showed abnormal development of secondary sexual characteristics during puberty,including 8 cases with masculine manifestations or abnormal menstruation after menarche(7 cases with sex cord stromal cell tumor and 1 case with cystic granulosa cell tumor),2 cases with primary amenorrhea(1 case with androgen insensitivity syndrome combined with testicular sertoli cell tumor and 1 case with endometriosis cyst combined with reproductive tract malformation),and 1 case diagnosed as 46,XX gonadal dysplasia with serous cystadenoma and no secondary sexual development during puberty. Conclusions Sex hormone levels should be actively tested in the case of prepubertal secondary sexual characteristics appearing early,pubertal secondary sexual characteristics being abnormal(underdevelopment),and/or menstrual abnormalities.Imaging examination should be performed to exclude ovarian organic lesions,and chromosome karyotype analysis should be performed if necessary.The diagnosis of ovarian mass in preadolescent and adolescent females with related symptoms should first be alerted to cord stromal cell tumor.It is recommended to rule out the possibility of combined reproductive tract malformation in the adolescent patients with primary amenorrhea.Chromosome examination should be conducted to rule out the possibility of gonadal dysplasia in the adolescent patients with primary amenorrhea and/or no development of secondary sexual characteristics.

Ovarian fibrosarcoma: A single-institution experience and a review of the literature.

Ovarian fibrosarcoma is an extremely rare and malignant sex cord-stromal tumor. Due to its low incidence and poor prognosis, until now, very few cases have been reported, and most of the reported cases have been sporadic. Therefore, the treatments and prognostic factors of ovarian fibrosarcoma are still debatable. Here, we report 5 cases of ovarian fibrosarcoma that presented at Peking Union Medical College Hospital over the past 20 years. The 5 patients were 41, 51, 54, 76, and 76 years of age when initial symptoms of pelvic mass or pain appeared. On ultrasound, this disease usually manifests as unilateral pelvic masses, within which uneven echo enhancement and some blood flow signals are observed. No significant increase was observed in the levels of preoperative tumor markers, such as serum CA125 and sex hormones. The final diagnosis depends on postoperative histopathological results since these tumors are easily misdiagnosed when intraoperative frozen sections are used for examination. Pathologic examinations showed that the tumor cells were spindle-shaped with moderate to severe atypia and high mitotic counts. The immunohistochemistry profile is not specific, but the positive rate of Ki-67 was consistent with the degree of malignancy and the prognosis of patients with this tumor. In addition, the tumor may also be positive for Vimentin, α-inhibin, SMA, estrogen receptor and progesterone receptor. Significant differences were observed in the surgical methods used, and no unified chemotherapy regimen has been established. The overall survival was > 15, >7, > 6, <1, and < 1 year for each patient. After reviewing the literature, evidence-based large-scale case studies were lacking. For treatments, complete cytoreductive surgery plus regimens typically used against malignant sex cord-stromal tumors, as described in the NCCN guidelines, are recommended. Due to its low incidence, both multicenter clinical studies and molecular studies are required to provide gynecologists with a better understanding and guidance for future management of patients with ovarian fibrosarcoma.

Ovarian metastasis from nongynecologic primary sites: a retrospective analysis of 177 cases and 13-year experience.

BACKGROUND: Metastasis to the ovary from nongynecologic organs accounts for 9% of all ovarian malignancies. Although the most common nongynecologic primary site of ovarian metastasis is the gastrointestinal tract, metastasis from other sites to the ovary is not uncommon. Differential diagnosis of primary and metastatic ovarian tumors is important; otherwise, appropriate treatment cannot be determined. Furthermore, an optimal treatment strategy for ovarian metastasis from nongynecologic primary sites still needs to be explored. METHODS: One hundred seventy-seven patients with ovarian metastasis from nongynecologic primary sites admitted to Peking Union Medical College Hospital between May 2005 and May 2018 were retrospectively evaluated. RESULTS: The mean age was 48 years (range, 18-83). Approximately 60% of patients were premenopausal women. The two most common nongynecologic primary sites of ovarian metastasis were the colorectum (68 cases) and stomach (61 cases). In addition to the most common symptoms of abdominal distension (39.0%), abdominal pain (37.9%), and ascites (27.7%), 18.1% of patients presented with abnormal uterine bleeding. Half of the patients who tested serum CA-125 preoperatively had elevated CA-125 levels within the range of 35 U/ml to 200 U/ml. More than 70% of synchronous ovarian metastases were preoperatively misdiagnosed as primary ovarian cancer. Of all included cases, 56.5% achieved optimal cytoreductive surgery (the diameter of the largest residual lesion < 2 cm). The overall 5-year survival rate and median survival time were 10% and 20 months, respectively. The primary site, optimal cytoreductive surgery, tumor differentiation, and postoperative adjuvant treatment were identified as prognostic indicators. CONCLUSIONS: The colorectum and stomach are the most common nongynecologic primary sites of ovarian metastasis. Synchronous ovarian metastasis is easily misdiagnosed as primary ovarian cancer. Optimal cytoreductive surgery and postoperative adjuvant treatment can be performed to confer survival benefit in selected patients.

Fertility-Sparing Treatment in Young Patients With Grade 2 Presumed Stage IA Endometrioid Endometrial Adenocarcinoma.

Purpose: To investigate the efficacy of fertility-sparing treatment for young women with grade 2 presumed stage IA endometrioid endometrial adenocarcinoma (EEA). Methods: We performed a retrospectively review of eight patients affected by grade 2 presumed stage IA endometrioid endometrial adenocarcinoma who underwent fertility-sparing treatment in the Peking Union Medical College Hospital between 2011 and 2018. Results: The median age of patients was 26 years (range, 22-35 years). Complete response (CR) was found in seven of the eight cases. The median time to response was 3 months (range, 3-9 months). Among patients who achieved CR, three had recurrence and were treated with second-line fertility-sparing therapy. Two of the three recurrent patients achieved CR, and one patient subsequently conceived. Pregnancies and successful deliveries were achieved in two of four patients. The average follow-up period was 31 months (range, 21-77 months). Conclusions: Fertility-sparing therapy is a feasible treatment option in patients with presumed stage IA, grade 2 endometrial cancer. Although our results are encouraging, they are based on very limited numbers, and patients should be informed the risk of tumor progression during treatment. Further evaluations are still required before recommending fertility-sparing therapy to endometrial cancer patients with more advanced disease in routine practice.

Clinicopathological Characteristics and Treatment Outcomes of Pregnancy Complicated by Malignant Ovarian Germ Cell Tumors.

PURPOSE: This study aimed to analyze the clinicopathological features, treatment, and feto-maternal outcomes of pregnancy complicated by malignant ovarian germ cell tumors (MOGCTs), to increase the awareness on this condition. PATIENTS AND METHODS: We retrospectively reviewed the medical records of patients diagnosed with MOGCTs during pregnancy, who were treated and followed-up at Peking Union Medical College Hospital from January 2000 to December 2017. The demographic characteristics, pathological features, treatment and prognosis were analyzed. RESULTS: The histological subtypes varied in 14 patients (dysgerminoma, n=1; immature teratoma, n=4; yolk sac tumor, n=6; and mixed germ cell tumors, n=3). Ten (71.4%) patients, including three who opted for conservative therapy until childbirth, one who only received salvage chemotherapy during pregnancy, and six who underwent cystectomy or unilateral salpingo-oophorectomy during pregnancy, desired fetal preservation. After undergoing surgery, four patients chose surveillance instead of timely adjuvant chemotherapy. Eight patients delivered their babies, and the preterm delivery rate was 50.0%. One newborn died of premature birth. The median follow-up period was 44 (range: 13 to 86) months. During the current study period, 12 patients had survived and did not report any diseases. However, two died due to disease progression. CONCLUSION: Pregnant women with MOGCTs had favorable outcomes. However, when a malignant tumor is suspected, surgery cannot be avoided. Thus, instead of timely postoperative adjuvant chemotherapy, close surveillance may be an acceptable alternative for pregnant women with low-risk MOGCTs.

Postchemotherapy sarcoma as a somatic-type malignancy derived from the gonadal yolk sac tumor in a patient with 46, XY pure gonadal dysgenesis.

46, XY pure gonadal dysgenesis (PGD) is characterized as a female phenotype with strip-like gonads, which has a high tendency to develop into gonadal tumors. Somatic-type malignancies of germ cell tumors (SMs of GCTs) refer to the presence of malignant non-germ cell histologies admixed with GCTs, which are usually chemoresistant and indicate poor prognosis. This case report aimed to analyze the special histological type of GCTs and the importance of salvage surgery in the treatment of refractory GCTs. We report a unique case of gonadal yolk sac tumor (YST) transformed into SMs in a patient with 46, XY PGD. This 18-year-old woman underwent laparoscopic pelvic tumor resection, considered her first surgery, 2 years ago, and pathology revealed YST with initial alpha-fetoprotein (AFP) level measuring >3,000 ng/mL. She underwent seven cycles of chemotherapy, and the AFP level decreased to within a normal range after the second cycle. However, a computed tomography scan after the seventh cycle revealed abdominal and pelvic metastases, and vaginal bleeding was continuously observed. Laparoscopic exploration and laparotomy with tumor subtotal resection were performed. A pathology report showed SMs (sarcoma) derived from YST. Whole exome sequencing demonstrated that the main somatic mutation was a non-synonymous mutation of KRAS (c.182A>G), and this result did not show any indications for targeted drugs. She received three cycles of PEI (cisplatin, etoposide, and ifosfamide) chemotherapy but showed no response. She refused to undergo further treatment and has been alive with the disease for 7 months. This suggests that SMs may be one of the reasons for chemoresistance of refractory GCTs, and salvage surgery may be one of the most effective treatments for this patient. Targeted therapy may be a new choice for chemoresistant GCTs, but drug selection must be based on gene sequencing, and its efficacy still needs to be verified by further study.

Genomic Comparison of Endometrioid Endometrial Carcinoma and Its Precancerous Lesions in Chinese Patients by High-Depth Next Generation Sequencing.

Endometrial intraepithelial neoplasia (EIN), also known as endometrial atypical hyperplasia (EAH) is believed to be the precursor lesion of endometrioid endometrial carcinoma (EEC). Many genetic factors play important roles in the process of carcinogenesis, however, the key genetic alterations from dysplasia to endometrial cancer remains poorly understood. Germline mutations in Lynch syndrome genes are associated with hereditary endometrial carcinoma. The role of other cancer susceptibility genes is unclear. The aim of this study was to investigate the genomic alterations of premalignant endometrial lesion and EEC, and to determine the prevalence of cancer predisposition gene mutations in an unselected endometrial carcinoma patient cohort. Here, we applied a comprehensive cancer gene panel (363 cancer-related genes) to capture the exomes of cancer-related genes. Samples were collected from 79 patients with EEC and 36 patients with EIN. Our results demonstrate that EIN harbors most of the driver events reported in EEC and for the first time we reported a high frequency of the amplification of VEGFB gene in endometrial cancer. Moreover, we identified four novel candidate cancer-associated genes (CTCF, ARHGAP35, NF1, and KDR) which may be crucial in the carcinogenesis of EEC. In addition, we identified 2 patients who had a deleterious germline mutation in Lynch syndrome genes (MLH1 and MLH2), and another 8 patients harbored germline mutations of 6 non-Lynch syndrome genes (MUTYH, GALNT12, POLE, MPL, ATM, and ERCC4) which may be associated with endometrial cancer. Larger series will have to be investigated to assess the risks and the proportion of endometrial cancers attributable to other genes.

Prolonged conservative treatment in patients with recurrent endometrial cancer after primary fertility-sparing therapy: 15-year experience.

OBJECTIVE: To evaluate the efficacy and prognosis of repeated treatment on patients with recurrent endometrial cancer (EC) after complete remission for primary fertility-preserving therapy. MATERIALS AND METHODS: We performed a retrospective study of patients with presumed stage IA endometrial cancer who had recurrence after achieving complete remission by fertility-preserving management at the Department of Obstetrics and Gynecology, Peking Union Medical College Hospital, from January 2003 to April 2018. For each patient, medical records and pathology reports were reviewed. The demographic features, treatment efficacy, tumor prognosis, and reproductive outcome were analyzed. RESULTS: Of the 41 recurrent patients with a median disease-free interval period of 16 months (range, 5-55 months), 23 were diagnosed at recurrence as EC, and 18 were diagnosed as atypical hyperplasia (AH) or endometrial intraepithelial neoplasia (EIN). 26 patients received repeated fertility-preserving treatment, and 23 patients were evaluable for efficacy. The complete response (CR) rate of repeated treatment (19/23, 82.6%) was lower than that of primary fertility-preserving treatment (161/170, 94.7%) with borderline significance (P = 0.053). The CR rate of AH/EIN patients was higher than that of EC patients with no statistical difference (92.9% vs 66.7%, P = 0.260). Among 19 patients achieved CR, 3 got pregnant and delivered successfully, while 3 had a second relapse. Four cases failed to response to the repeated treatment and underwent definitive surgery. 15 patients referred to definitive surgery directly after recurrence and one of them had a pelvic recurrence after 120 months. All patients are alive without evidence of disease at last follow-up. CONCLUSIONS: For patients with recurrent EC after primary fertility-preserving treatment, repeated fertility-preserving treatment can still achieve a promising response and patients have possibilities of completing childbirth.

Clinicopathological and survival analysis of uterine papillary serous carcinoma: a single institutional review of 106 cases.

OBJECTIVES: The objectives of this study were to analyze clinicopathological features and to investigate the prognostic determinants in patients with uterine papillary serous carcinoma (UPSC). MATERIALS AND METHODS: A cohort of 106 UPSC patients diagnosed and treated at Peking Union Medical College Hospital between 2000 and 2016 were retrospectively reviewed. The Kaplan-Meier method and Cox regression analysis were used for survival analysis. Differences between categorical data were calculated by using the chi-squared test. RESULTS: The median follow-up was 29.0 months (range =2-170 months), with an overall recurrence rate of 35.8%. The coincidence rate between preoperative endometrial sampling and postoperative definitive pathology of hysteroscopy group was significantly higher than that of the dilation and curettage group (88.5% vs 65.0%, P=0.019). Adjuvant therapy-treated patients with stage I UPSC experienced significantly fewer recurrences than those receiving observation (P=0.003). Patients with advanced-stage UPSC who received combination therapy demonstrated a lower risk of local recurrence compared with those who received chemotherapy alone with a borderline significance (P=0.051). Elevated serum cancer antigen 125 level was associated with advanced-stage disease and recurrence (P<0.001). In multivariate analysis, tumor stage and optimal cytoreduction were independent predictors of survival. In substage analysis, complete surgical staging was associated with better overall survival (OS; yes vs no, HR: 0.05 [95% CI: 0.01-0.51], P=0.037) in patients with stage I UPSC. As for advanced stage, paclitaxel-platinum chemotherapy regimen and optimal cytoreduction were independent favorable prognostic factors for progression-free survival (paclitaxel-carboplatin [TC] vs other; HR =0.38, P=0.010; yes vs no, HR =0.45, P=0.032) and OS (TC vs other, HR =0.38, P=0.022; yes vs no, HR =0.54, P=0.013). CONCLUSION: In patients with stage I UPSC, complete staging was associated with better OS, and therefore, it should be performed in all patients. Tumor stage and optimal cytoreduction are the most significant prognostic factors. Recurrence can be improved in stage I patients treated with adjuvant therapy and in patients with advanced-stage disease treated with combined therapy. TC regimen may be the preferred regimen for chemotherapy.

Malignant mixed ovarian germ cell tumor composed of immature teratoma, yolk sac tumor and embryonal carcinoma harboring an EGFR mutation: a case report.

Malignant mixed ovarian germ cell tumors are very rare, accounting for ~5.3% of all malignant ovarian germ cell tumors (MOGCTs), with a very high degree of malignancy. The treatment of patients with persistent, refractory, or platinum-resistant MOGCT is not well defined. The objective of this case report was to analyze the importance of chemotherapy, salvage surgery and target therapy in the treatment of a patient with refractory OGCT after first-line chemotherapy failure. We reported a 34 year-old woman suffered from advanced refractory MOGCT after first-line chemotherapy, cytoreductive surgery, and a series of chemotherapy. The genetic test shows she is a carrier of EGFR: p.L858R mutation. Based on genetic testing result, she received icotinib which targeted for EGFR mutation, but the tumor progressed. After a secondary cytoreductive surgery, she exhibited a partial response and continued to receive chemotherapy. This suggests that salvage surgery may be considered for patients with persistent or refractory MOGCTs when no effective systemic treatment option is available. Targeted therapies based on gene sequencing may provide a new option; however, its efficacy and related resistance mechanisms still need to be verified by further study.

Efficacy of neoadjuvant cisplatin and 5-flourouracil prior to surgery in FIGO stage IB2/IIA2 cervical cancer.

Cervical cancer is currently the first or second leading cause of cancer-related mortality among women in developing countries. This study was conducted in order to determine whether neoadjuvant cisplatin and 5-flourouracil (NAPF) prior to surgery is superior to primary surgical treatment (PST) as a treatment option for patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IB2/IIA2 cervical cancer. A retrospective review of 195 patients with early-stage bulky cervical cancer was performed. The patients were divided into two groups, according to whether they received NAPF prior to surgery. The surgical profiles and complications, risk factors of recurrence and survival were compared between the groups. The response rate to NAPF was found to be 61.2%. There were no differences in operative time and intra-operative complications between the two groups, whereas the estimated blood loss in the NAPF and PST groups were 620.1±394.9 and 434.8±233.7 ml, respectively (P=0.000). When compared with PST, NAPF remarkably reduced tumor size (22.5 vs. 93.3%, P=0.000). Furthemore, the ratio of deep stromal invasion was significantly lower in responders to NAPF compared with that in non-responders (46.7 vs. 76.3%, respectively; P=0.004) and in the PST group (46.7 vs. 70.0%, respectively; P=0.004). No reduction of high-risk factors (HRFs) was observed. The NAPF group, even the responder subgroup, exhibited no significant improvement in progression-free survival (PFS) and overall survival (OS) compared to the PST group. In conclusion, despite the reduction of intermediate-risk factors (IRFs), neoadjuvant chemotherapy (NAC) with the NAPF regimen prior to radical surgery (RS) did not improve the prognosis in patients with FIGO stage IB2/IIA2 cervical cancer.

Congenital perineal mass with cervovaginal duplication: a case report and literature review.

BACKGROUND: Congenital perineal mass is rare. Although there have been several reports describing male neonates with a perineal mass with urogenital anomalies, no similar cases have been reported in female infants. CASE: We present a case of a 17-month-old girl with a congenital, slowly enlarging perineal mass with cervovaginal duplication. Excision of the mass was performed and histopathogic examination revealed it to be a hamartoma. CONCLUSION: Congenital perineal mass may be the result of urorectal septum outgrowth and it is likely to be associated with urogenital and/or anorectal anomalies.

Analysis of 30 patients with persistent or recurrent squamous cell carcinoma of the cervix within one year after concurrent chemoradiotherapy.

OBJECTIVE: To investigate the recurrence sites, risk factors, and prognosis of patients with persistent or recurrent squamous cell carcinoma (SCC) of the cervix within one year after undergoing concurrent chemoradiotherapy (CCRT). METHODS: Clinical data of 30 patients with persistent or recurrent SCC of the cervix within one year after CCRT between July 2006 and July 2011 were analyzed retrospectively. These data were compared with those of 35 SCC cases with no signs of recurrence after complete remission. These 35 patients were treated during the same period (between 2006 and 2011) and selected randomly. RESULTS: Among these 30 patients, 25 exhibited distant metastases of which 14 were observed within 6 months after CCRT. Univariate analysis showed higher incidence of pelvic or para-aortic lymphadenectasis and SCC-ag >10 ng/mL in the group with persistent or recurrent disease before treatment (P<0.01). Multivariate analysis by logistic regression revealed that the pre-therapeutic pelvic or para-aortic lymph node enlargement and SCC-ag >10 ng/mL were the independent risk factors. Palliative chemotherapy was the main treatment option for patients with persistent or recurrent disease. The 2-year survival rate was 21.7%, and the median survival time was 17 months. CONCLUSION: Patients with persistent or recurrent SCC of the cervix after CCRT exhibited a high rate of distant metastasis with poor prognosis. The pre-therapeutic pelvic or para-aortic lymph node enlargement and SCC-ag >10 ng/mL were identified as the independent risk factors for persistent or recurrent SCC within 1 year after CCRT.

[Pregnant rate and pregnancy-relating factors of patients with early endometrial carcinoma and severe atypical hyperplasia of endometrium after fertility-preserving treatment by progestin].

OBJECTIVE: To summarize the pregnant rate of patients with early endometrial carcinoma and severe atypical hyperplasia after fertility-preserving treatment and analyze their pregnancy-relating factors. METHODS: Endometrial curettage was used to evaluate the therapy response of endometrium after every 3 months of administration of high-dose progestin as fertility-sparing treatment for 51 patients with stage I endometrial carcinoma or severe endometrial atypical hyperplasia from Jun. 1996 to Jan. 2010. Individualized maintained treatment was given to patients after achieving complete remission of the endometrium. Pregnant results and pregnancy-relating factors were analyzed retrospectively. RESULTS: The median age of all the 51 patients was 29 years old. Forty-five (88%, 45/51) achieved complete response. Of the 34 cases who desired to conceive after complete response, 16 of them had 22 pregnancies, the pregnant rate was 47% (16/34); and 12 women obtained healthy live birth baby, the fertility rate was 35% (12/34). The pregnant rate of patients at age >35 or ≤ 35 was 0/2 and 50% (16/32) respectively (P > 0.05). The pregnant rate of patients with or without infertility was 40% (8/20) and 8/14, with endometrial cancer or severe atypical hyperplasia was 40% (10/25) and 6/9, respectively (all P > 0.05). The pregnant rate of patients who received in vitro fertilization-embryo transfer, ovulation promotion, or no treatment was 7/7, 6/16 and 3/11 respectively (P < 0.01). CONCLUSIONS: Fertility-preserving treatment for early endometrial cancer and severe atypical hyperplasia with high-dose progestin could achieve higher response rate. Assisted reproductive technologies could significantly increase the chance of conception.

[Multicenter randomized controlled clinical study for the operative treatment of malignant ovarian germ cell tumors].

OBJECTIVE: To investigate the operative treatment for first-treated patients with malignant ovarian germ cell tumors who need preservation of fertility. METHODS: The clinical data of 105 patients who were treated with fertility-sparing surgery in 11 hospitals from 1992 to 2010 were collected to evaluate the outcomes of different primary surgical operative procedures. All 105 cases were performed the surgeries that preserved fertility and divided into three groups according to the surgical approaches, comprehensive staging surgery group: 47 cases (44.8%) received comprehensive staging surgeries that including the ipsilateral oophorectomy + omentectomy + retropertoneal lymph node dissection ± appendectomy + multiple biopsies;oophorectomy group:45 cases (42.9%)received ipsilateral oophorectomy ± biopsy of contralateral ovary ± omentectomy;tumor resection group:13 cases (12.4%) received enucleation of the mass with preservation of the ovary. Differences were compared among the three groups of patients in the surgery-related indicators, complications, fertility and prognosis. RESULTS: (1) Surgery-related indicators:the average blood loss of the comprehensive staging surgery group, the oophorectomy group and the tumor resection group were 496, 104 and 253 ml, the mean operation time were 176, 114 and 122 minutes, respectively, and there were significant differences among three groups (P = 0.011, P = 0.000). (2) Complication:the surgical complication rates of the three groups were 17% (8/47), 0 and 1/13, with significant differences (P = 0.015). (3) Reproductive function status: the pregnancy rate and birth rate of the three groups were no significant differences (9/19 vs. 7/19 vs. 2/3, P = 0.515; 8/19 vs. 5/19 vs. 2/3, P = 0.636). (4) PROGNOSIS: the recurrence rate of the three groups were significant differences [13% (6/47) vs. 0 vs. 2/13, P = 0.013], but the death rate with no significant differences [6% (3/47) vs. 0 vs. 0, P = 0.129]; The five-year survival rate of three different groups were 89%, 100% and 100% (P > 0.05), while disease free survival rate were 85%, 100% and 83% (P < 0.05), respectively. CONCLUSIONS: Compared with comprehensive staging surgery, oophorectomy group have higher surgical security and satisfactory prognosis, considerable pregnancy rates and birth rate. The tumor resection security may be reliable, but the prognosis is poor.

Preoperative neutrophil-lymphocyte and platelet-lymphocyte ratios as independent predictors of cervical stromal involvement in surgically treated endometrioid adenocarcinoma.

BACKGROUND: The purpose of this study was to evaluate the relationship between preoperative inflammatory markers (neutrophil-lymphocyte ratio and platelet-lymphocyte ratio) and cervical stromal involvement in patients with endometrioid adenocarcinoma. METHODS: We studied 318 patients with endometrioid adenocarcinoma who underwent comprehensive surgical staging. We used univariate and multivariate analyses of cervical stromal involvement and receiver-operating curves to calculate optimal cutoff values for neutrophil-lymphocyte and platelet-lymphocyte ratios to predict cervical stromal involvement. RESULTS: The presence of cervical stromal involvement was associated with neutrophil-lymphocyte ratio and platelet-lymphocyte ratio (P = 0.009 and P = 0.031, respectively). Multivariate analysis showed that higher neutrophil-lymphocyte and platelet-lymphocyte ratios independently predicted cervical stromal involvement (odds ratio 3.10, 95% confidence interval 1.10-8.76, P = 0.032, and odds ratio 5.27, 95% confidence interval 1.94-14.35, P = 0.001, respectively). At a threshold of 2.01, the neutrophil-lymphocyte ratio was 71.0% sensitive and 63.8% specific for stromal involvement; at a 172.24 threshold, the platelet-lymphocyte ratio was 48.4% sensitive and 88.9% specific. CONCLUSION: Preoperative neutrophil-lymphocyte and platelet-lymphocyte ratios can help identify the risk of cervical stromal involvement in patients with endometrial cancer. Evaluating these ratios may help select patients who should be particularly watched and tested for cervical stromal involvement.
