ABSTRACT
Objective: To determine the oncofertility outcomes and prognostic factors in a large series of serous borderline ovarian tumor-micropapillary variant (SBOT-M) with a long-term follow-up. Methods: Consecutive patients with SBOT-Ms treated from two affiliated hospitals of the Chinese Academy of Medical Sciences were retrospectively reviewed. Prognostic factors on invasive recurrence, disease-free survival (DFS), and overall survival were analyzed, and outcomes of patients treated with conservative and radical surgery were compared. Results: From 2000 to 2020, 200 patients were identified and followed. After a median follow-up of 68 months, 81 patients relapsed. In the multivariate analyses, younger age at diagnosis and conservative surgery that preserved fertility potential were independently associated with worse DFS (p = 0.018 and <0.001, respectively). Twenty-three patients experienced invasive recurrence, and seven died of progressive disease. Multivariate analysis showed that nulliparous and advanced FIGO stage were independently adversely associated with lethal recurrence (p = 0.022 and 0.029, respectively). Only advanced FIGO stage at diagnosis was associated with worse overall survival at univariate analysis (p = 0.02). Among 61 patients attempting conception, 37 achieved 44 pregnancies and resulted in 32 live births. Conclusions: In this series, patients with SBOT-M have an acceptable oncofertility outcomes. The use of conservative surgery was independently associated with worse DFS, but without an impact on neither invasive relapse nor on overall survival. Patients with advanced FIGO stages had a significantly higher risk of lethal recurrence and worse overall survival, suggesting that adequate staging surgery and intensive postoperative surveillance should be warranted.
ABSTRACT
Estrogen and progesterone are the major determinants of the occurrence and development of endometrial cancer (EC), which is one of the most common gynecological cancers worldwide. Our purpose was to develop a novel estrogen/progesterone-related gene signature to better predict the prognosis of EC and help discover effective therapeutic strategies. We downloaded the clinical and RNA-seq data of 397 EC patients from The Cancer Genome Atlas (TCGA) database. The "limma" R package was used to screen for estrogen/progesterone-related differentially expressed genes (DEGs) between EC and normal tissues. Univariate and multivariate Cox proportional hazards regression analyses were applied to identify these DEGs that were associated with prognosis; then, a novel estrogen/progesterone-related prognostic signature comprising CDC25B, GNG3, ITIH3, PRXL2A and SDHB was established. The Kaplan-Meier (KM) survival analysis showed that the low-risk group identified by this signature had significantly longer overall survival (OS) than the high-risk group; the receiver operating characteristic (ROC) and risk distribution curves suggested this signature was an accurate predictor independent of risk factors. A nomogram incorporating the signature risk score and stage was constructed, and the calibration plot suggested it could accurately predict the survival rate. Compared with normal tissues, tumor tissues had increased mRNA levels of GNG3 and PRXL2A and a reduced mRNA level of ITIH3. The knockdown of PRXL2A and GNG3 significantly inhibited the proliferation and colony formation of Ishikawa and AN3CA cells, while the inhibition of PRXL2A expression suppressed xenograft growth. In this study, five estrogen/progesterone-related genes were identified and incorporated into a novel signature, which provided a new classification tool for improved risk assessment and potential molecular targets for EC therapies.
ABSTRACT
OBJECTIVE: To analyze the clinical characteristics, influencing factors and outcome of recurrent patients with early stage bulky cervical carcinoma. METHODS: Between January 1(st) 2000 and December 31(st) 2009, 76 patients with stage Ib2 and IIa2 bulky cervical carcinoma developed recurrence and (or) metastasis. The recurrence time, recurrence location, recurrence-related factors, treatment and survival were analyzed. RESULTS: The median follow up was 44 months (9-137 months). The overall recurrence and (or) metastasis rate was 22.6%. The 1-, 1-2, 3-5 and 5-year recurrence and (or) metastasis rates were 38.2%, 27.6%, 30.3% and 3.9%, respectively. The 5-year survival rate of local recurrence was 34.5%, that of distant metastasis was 23.6%, and that of distant metastasis with synchronous pelvic recurrence was 11.1%, (P = 0.555). The 5-year survival rate of patients who received surgery plus chemotherapy, radiation plus chemotherapy and chemotherapy alone after recurrence and (or) metastasis were 53.3%, 30.7% and 24.6%, respectively (P = 0.686). Univariate analysis demonstrated that tumor recurrence and (or) metastasis in patients of the stage Ib2 and IIa2 bulky cervical carcinoma were influenced by the disease stage, pelvic lymph node metastasis, deep cervical stromal invasion, lymphovascular tumor thrombus and pathological types. Multivariate regression analysis demonstrated that pelvic lymph node metastasis, lymphovascular tumor thrombus and pathological types were the key factors affecting the recurrence and (or) metastases of the stage Ib2 and IIa2 bulky cervical carcinoma. Subgroup analysis showed that pelvic lymph node metastasis and stage were the main factors affecting the local recurrence in those patients, and the pathological type, vascular tumor thrombus and pelvic lymph node metastasis were the main factors affecting the distant metastasis. CONCLUSIONS: Recurrence and(or) metastasis of early stage bulky cervical cancer are mostly happened within 2 years post operation. Patients with pelvic lymph node metastasis have high probability to develop local recurrence and distant metastasis. Patients with non-squamous cell carcinoma and lymphovascular tumor thrombus are more likely to develop distant metastasis. Neoadjuvant chemotherapy does not decrease local recurrence and distant metastasis in patients with stage Ib2 and IIa2 bulky cervical carcinoma. Individualized treatment is advised for recurrent patients.

OBJECTIVE: To discuss the clinical characteristics, treatment and prognostic factors of brain metastasis from gynecological cancers. METHODS: Clinical records of 25 brain metastasis patients from gynecological cancers admitted from January 1999 to January 2009 were reviewed retrospectively. The curative effects of different treatments were compared. The prognostic factors were determined using the Cox regression model. RESULTS: There were 14 cases ovarian malignant tumor, 6 cases cervical carcinoma and 5 cases uterine malignant tumor. Seven cases (28%, 7/25) had solitary metastatic lesion in the brain. Extracranial metastases were detected in 18 cases (72%, 18/25). Five patients only received one kind of treatment, and the mean survival time was 4.0 months (0.5 to 9.5 months). Sixteen patients received combined treatment, 3 of them received combined treatment including surgery, and the mean survival time was 8.4 months (4.1 to 13.4 months); 13 of them received chemotherapy and radiotherapy, and the mean survival time was 14.2 months (4.3 to 58.1 months). Four patients received only palliative supportive care, and the survival time was only 0.1 to 1.0 month. The Cox regression model showed that Karnofsky performance status scale, with or without extracranial metastases and the treatment method were the independent prognostic factors of brain metastasis from gynecological cancers (P < 0.05). CONCLUSION: The incidence of brain metastasis from gynecological cancers is low and the prognosis is very poor. Combined treatments may get better effects.

OBJECTIVE: To discuss the prognostic factors of recurrent ovarian epithelial carcinoma and to analyze the curative effect of post-relapse treatment. METHODS: The clinical records of 293 patients with ovarian epithelial carcinoma were reviewed retrospectively. There were 199 recurrent cases during the following up. RESULTS: All the 199 patients received chemotherapy. And 173 patients only received chemotherapy. 16 patients received surgery and chemotherapy and the other 10 patients received radiotherapy and chemotherapy. 158 patients received platinum-based chemotherapy again and 41 patients received chemotherapy without platinum. The response rate of all the patients was 43.7% (87/199), the response rate of only chemotherapy was 39.9% (69/173), the response rate of surgery and chemotherapy was 75.0% (12/16), and the response rate of radiotherapy and chemotherapy was 60.0% (6/10). The patients were divided into four groups according to the progression free interval (PFI). The response rates in groups that PFI < or = 6 months, 7 - 12 months, 13 - 24 months and > 24 months were 5.1%, 47.2%, 82.1% and 96.0%, respectively. The median survival time in the 16 patients received second cyto-reductive surgery was 41 months. Multivariate analysis revealed that PFI was significantly correlated with prognosis of recurrent ovarian epithelial carcinoma (OR = 0.589, P = 0.021). CONCLUSION: PFI is an individual prognostic factor for survival of recurrent ovarian epithelial carcinoma. PFI is significantly associated with the response rate of chemotherapy. Optimal secondary cytoreductive surgery may improve the overall survival of recurrent patients. The response rate of paclitaxel plus platinum chemotherapy in platinum-sensitive patients is higher than that of other platinum-based chemotherapy.
