Project description:ObjectiveWe aimed to analyse the clinical value of primary site surgery in improving the cancer-specific survival (CSS) and overall survival (OS) of initial metastatic cervical cancer patients.DesignA population-based retrospective study.SettingNational Cancer Institute's Surveillance, Epidemiology and End Results database.ParticipantsWe analysed 1390 patients with the International Federation of Gynecology and Obstetrics 2009 stage IVB cervical cancer with complete clinical data treated between 2010 and 2016.InterventionsPrimary site surgery.MeasuresPropensity score matching (PSM) with a ratio of 1:2 was used to balance measure covariates of comparison groups. Survival time was calculated using Kaplan-Meier methods and compared by the log-rank test. To eliminate the bias of site-specific metastasis, clinicopathological factors and subsequent therapy on survival analysis, subgroup analyses stratified by metastasis type, clinicopathological factors and subsequent therapy were employed to evaluate the effect of cervical surgery on survival. Combination of directed acyclic graph and change-in-estimate procedures was performed to indentified confounders, and Cox regression was used to assess the survival benefit of cervical surgery for primary metastatic cervical cancer patients. The consistency of our findings was evaluated through sensitivity analysis.ResultsMatching resulted in two comparison groups with minor differences in most variables. Pre-and-post-PSM, the median CSS and OS in the surgery group were 1.3 and 1.5, 1.1 and 1.2 times of those in the non-surgery group, respectively. Primary site surgery conferred prognosis superiority for patients with metastases to distant lymph node and other sites rather than organ metastases. After PSM and adjusting confounders, local surgery reduced the cancer related and overall mortality rates by 31% and 30%, respectively.ConclusionsSurgical procedures could promote survival in patients with primary metastatic cervical cancer and should be considered a therapeutic option for carefully chosen patients.

Project description:The purpose of the present study was to investigate the expression of TAp73 and ΔNp73 in cervical squamous cancer cells, and to evaluate the prognostic significance of TAp73 and ΔNp73 expression in patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-II cervical squamous cell carcinoma (SCC). The immunohistochemical expression of TAp73 and ΔNp73 was evaluated in 59 FIGO stage I-II cervical SCC tumor samples. Correlations with clinicopathological characteristics were determined by χ2 test. The prognostic impact of TAp73 and ΔNp73 expression with regard to overall survival (OS) was determined by the Kaplan-Meier method. High TAp73 and ΔNp73 expression was detected in 79.7% (47/59) and 76.3% (45/59) of patients, respectively. The expression of TAp73 and ΔNp73 was not associated with age, FIGO stage, pathological differentiation or lymph node metastasis. The 3-year OS rates associated with low and high TAp73 expression were 75.0 and 83.0%, respectively (χ2=0.33; P=0.568), whereas those associated with low and high ΔNp73 expression were 100.0 and 75.6%, respectively (χ2=3.90; P=0.048). High expression levels of TAp73 and ΔNp73 were frequently observed in the cervical squamous cancer cells. Overall, high expression levels of ΔNp73 may indicate an unfavorable prognosis in patients with early-stage cervical SCC.

Project description:ObjectiveTo compare the prognostic value of International Federation of Gynecology and Obstetrics (FIGO) 2009 and 2018 staging systems in surgical patients with small cell neuroendocrine carcinoma of the cervix (SCNEC).MethodsWe re-staged 64 surgical IB-IIA (FIGO 2009) SCNEC patients according to the FIGO 2018 system and refined stage IIIC of FIGO 2018 based on tumor local invasion. The prognostic factors were analyzed, and the advantages of FIGO 2018 were compared with 2009.ResultsThe 5-year overall survival rate (OS) was 78.5% for stage I and 22.2% for stage II (FIGO 2009). In FIGO 2018, there was no difference between stage I and II, and the 5-year OS was 74.1%, 60.2%, and 0% for stage I/II, IIIC1, and IIIC2. After combining stage IIIC with the local invasion stage (T1 was limited to the cervix and vagina; T2 involved the parametrium; T3 involved the pelvic or abdominal cavity), the 5-year OS for stage IIICT1, IIICT2, and IIICT3 was 83.3%, 30.0%, and 0%, respectively.ConclusionsFor stage II SCNEC patients, FIGO 2009 underestimated the prognosis, while FIGO 2018 was more accurate. For stage IIIC, FIGO 2018 might be more individualized and accurate after combining stage IIIC with tumor local invasion.

Project description:BackgroundTransient receptor potential channel 1 (TRPC1) promotes tumor growth and metastasis in endometrial carcinoma (EC) cell lines, whereas its clinical role in EC management remains unclear. Therefore, this study aimed to investigate the association of TRPC1 protein expression with the clinical features and survival of EC patients, then was further validated by TRPC1 mRNA measurement and data from The Human Protein Atlas.MethodsTRPC1 protein expression in tumor tissues and normal endometria of 176 resectable EC patients was determined using immunohistochemistry. Besides, TRPC1 mRNA expression of partial patients (n = 80) was detected using RT-qPCR. Additionally, survival data from The Human Protein Atlas (derived from The Cancer Genome Atlas [TCGA]) was analyzed.ResultsTRPC1 protein expression was up-regulated in tumor tissue compared with normal endometrium (p < 0.001). Up-regulated TRPC1 protein expression was associated with stromal cervical invasion (p = 0.044), lymphovascular invasion (p = 0.032), and increased federation of gynecology and obstetrics (FIGO) stage (p = 0.005). Tumor TRPC1 protein high was linked with shortened accumulating disease-free survival (DFS) (p = 0.009) and overall survival (OS) (p = 0.026), which were also confirmed by multivariate Cox's regression analysis (both p < 0.050). Further, TRPC1 mRNA validation disclosed that TRPC1 mRNA high was related to shortened accumulating DFS (p = 0.038) and exhibited a correlating trend with declined OS (lacked statistical significance) (p = 0.162). Meanwhile, survival analysis on the data from The Human Protein Atlas (derived from TCGA) also exhibited that TRPC1 mRNA high was correlated with reduced accumulating OS (p < 0.001).ConclusionOur findings support TRPC1 as a prognostic biomarker in resectable EC patients.

Project description:ObjectiveTo evaluate the effect of parametrial status on FIGO stage IIIC1 cervical cancer.MethodsA retrospective study was conducted from June 1, 2009, to December 31, 2018.Patients with stage IIIC1 cervical cancer were included and stratified into two groups based on the status of parametrial involvement. Patients with IIIA or IIIB were selected as control. The primary outcomes are overall survival (OS) and progression-free survival (PFS).ResultsOf 586 patients included, 377 patients were stage IIIC1 (group A) and 209 patients were stage IIIA/IIIB (group B). Compared control, stage IIIC1 was not associated with worse 5-year OS or PFS. Of the stage IIIC1 patients, 58.1% without parametrial involvement (group A1) and 41.9% with parametrial involvement (group A2). Patients of group A1 showed a better prognosis than group A2 both in 5-year rates of OS (79.09% vs. 59.43%, p<0.001) and PFS (73.27% vs. 56.95%, p=0.0002). However, patients of group A1 showed a better prognosis than group B both in OS and PFS. Also, patients of group A2 showed a comparable prognosis to group B both in OS and PFS.ConclusionReclassification of stage IIIC1 cervical cancer without parametrial into a new stage is more appropriate and improves discriminatory ability.

Project description:BackgroundTo compare the oncological outcomes of patients with FIGO 2018 stage IIIC cervical cancer (CC) involving different local tumor factors who underwent abdominal radical hysterectomy (ARH), neoadjuvant chemotherapy and radical surgery (NACT), or radical chemoradiotherapy (R-CT).MethodsBased on tumor staging, patients with stage IIIC were divided into T1, T2a, T2b, and T3 groups. Kaplan-Meier and Cox proportional hazards regression analysis were used to compare their overall survival (OS) and disease-free survival (DFS) of 5 years.ResultsWe included 4,086 patients (1,117, 1,019, 869, and 1,081 in the T1, T2a, T2b, and T3 groups, respectively). In the T1 group, NACT was correlated with a decrease in OS (hazard ratio [HR] = 1.631, 95% confidence interval [CI]: 1.150-2.315, P = 0.006) and DFS (HR = 1.665, 95% CI: 1.255-2.182, P < 0.001) than ARH. ARH and NACT were not correlated with OS (P = 0.226 and P = 0.921) or DFS (P = 0.343 and P = 0.535) than R-CT. In the T2a group, NACT was correlated with a decrease in OS (HR = 1.454, 95% CI: 1.057-2.000, P = 0.021) and DFS (HR = 1.529, 95% CI: 1.185-1.974, P = 0.001) than ARH. ARH and NACT were not correlated with OS (P = 0.736 and P = 0.267) or DFS (P = 0.714 and P = 0.087) than R-CT. In the T2b group, NACT was correlated with a decrease in DFS (HR = 1.847, 95% CI: 1.347-2.532, P < 0.001) than R-CT nevertheless was not correlated with OS (P = 0.146); ARH was not correlated with OS (P = 0.056) and DFS (P = 0.676). In the T3 group, the OS rates of ARH (n = 10), NACT (n = 18), and R-CT (n = 1053) were 67.5%, 53.1%, and 64.7% (P = 0.941), and the DFS rates were 68.6%, 45.5%, and 61.1%, respectively (P = 0.761).ConclusionR-CT oncological outcomes were not entirely superior to those of NACT or ARH under different local tumor factors with stage IIIC. NACT is not suitable for stage T1, T2a, and T2b. Nevertheless ARH is potentially applicable to stage T1, T2a, T2b and T3. The results of stage T3 require confirmation through further research due to disparity in case numbers in each subgroup.

Project description:To evaluate treatment outcomes for patients with vulvar cancer with grossly positive pelvic lymph nodes (PLNs).From a database of 516 patients with vulvar cancer, we identified patients with grossly positive PLNs without distant metastasis at initial diagnosis. We identified 20 patients with grossly positive PLNs; inclusion criteria included PLN 1.5cm or larger in short axis dimension on CT/MRI (n=11), FDG-avid PLN on PET/CT (n=3), or biopsy-proven PLN disease (n=6). Ten patients were treated with chemoradiation therapy (CRT), 4 with RT alone, and 6 with various combinations of surgery, RT or CRT. Median follow-up time for patients who had not died of cancer was 47months (range, 4-228months).Mean primary vulvar tumor size was 6.4cm; 12 patients presented with 2009 AJCC T2 and 8 with T3 disease. All patients had grossly positive inguinal nodes, and the mean inguinal nodal diameter was 2.8cm. The 5-year overall survival and disease specific survival rates were 43% and 48%, respectively. Eleven patients had recurrences, some at multiple sites. There were 9 recurrences in the vulva, but no isolated nodal recurrences. Four patients developed distant metastasis within 6months of starting radiation therapy.Aggressive locoregional treatment can lead to favorable outcomes for many patients with grossly involved PLNs that is comparable to that of grossly involved inguinal nodes only. We recommend modification of the FIGO stage IVB classification to more accurately reflect the relatively favorable prognosis of patients with PLN involvement.

Project description:ObjectiveTo investigate the serum microRNAs as biomarkers in predicting chemoradiotherapy resistance in advanced-stage cervical squamous cell carcinoma (ACSCC) patients.MethodsSerum samples were collected from International Federation of Gynecology and Obstetrics (FIGO) stage IIB to IIIB cervical squamous cell carcinoma patients treated with platinum based Concomitant Chemoradiotherapy (CCRT) in our hospital during September 2013 to November 2015. Twenty well-matched samples (10 resistant and 10 sensitive) were chosen to screen the miRNA expression profile using serum samples pooled with microarrays. miRNAs expressed significantly different between two groups were further verified in 131 patients (29 resistant and 102 sensitive) serum samples with TaqMan Real-time PCR. The AUC was used to evaluate the accuracy of the biomarkers for prediction.ResultsMiR-136-5, miR-152-3p and miR-206 were expressed significantly different between sensitive and resistant groups. Results of 131 patients verification showed that the levels of miR-206 in sensitive samples and resistant samples were 2.715±0.2115 and 14.64±1.184, respectively, which was significantly different (P<.0001), while miR-136-5p and miR-152-3p could not be tested without pre-amplification reactions. Univariate analysis revealed that miR-206 expression was significantly associated with patients' DFS. Multivariate analysis demonstrated that miR-206 expression, tumor differentiation and pelvic lymph nodes metastasis were the independent prognostic factors associated with DFS in this cohort (P=.008, 0.000, 0.000, respectively). The probability of the prognostic accuracy of miR-206 expression in predicting chemoradiotherapy sensitivity of ACSCC patients was 91.3% (79.3% sensitivity and 92.2% specificity).ConclusionSerum miR-206 is a powerful tool in predicting chemoradiotherapy sensitivity in ACSCC patients.

Project description:ObjectiveThe purpose of this study was to analyze the impact of surgery of primary sites on stage IVB cervical cancer patients from a population-based database, the Surveillance, Epidemiology and End Results (SEER).MethodsPropensity score matching was performed to minimize heterogeneity in patient between with-surgery group and without-surgery group. Clinicopathological characteristics were compared using the χ² or Fisher's exact test. Survival analysis included the Kaplan-Meier method, log-rank test, and Cox proportional hazards model.ResultsBetween 2010-2015, a total of 1,139 International Federation of Gynecology and Obstetrics (FIGO) stage IVB cervical cancer patients receiving chemoradiotherapy (CRT) were included in this retrospective study. Within post-matching cohort, the median duration of overall survival (OS) in stage IVB cervical cancer patients receiving CRT was 22 months. The overall 5-year survival rate was 25.7%. The increasing American Joint Committee on Cancer T stage (T1 vs. T2, p=0.033, hazard ratio [HR]=1.79, 95% confidence interval [CI]=1.05-3.05; T1 vs. T3, p=0.003, HR=2.20, 95% CI=1.31-3.67; T1 vs. T4, p=0.037, HR=2.75, 95% CI=1.06-7.12) and visceral metastasis (with vs. without, p=0.038, HR=1.60, 95% CI=1.03-2.49) was reported as independent risk factors of OS. Surgery of primary sites combined with CRT tended to prolong the survival of stage IVB cervical cancer patients (p<0.001, HR=0.36, 95% CI=0.21-0.61) compared with CRT, especially for patients without visceral metastasis (p=0.005, HR=0.31, 95% CI=0.14-0.70).ConclusionsIn conclusion, patients with stage IVB cervical cancer may achieve their best outcomes through CRT combined with surgery of primary sites. However, it deserves large scale prospective clinical trials to confirm.

Project description:Clinical ribonucleotide reductase (RNR) inhibitors have reinvigorated enthusiasm for radiochemotherapy treatment of patients with regionally advanced stage cervical cancers. About two-thirds of patients outlive their cervical cancer (1), even though up to half of their tumors retain residual microscopic disease (2). The National Cancer Institute Cancer Therapy Evaluation Program conducted two prospective trials of triapine-cisplatin-radiation to improve upon this finding by precisely targeting cervical cancer's overactive RNR. Triapine's potent inactivation of RNR arrests cells at the G1/S cell cycle restriction checkpoint and enhances cisplatin-radiation cytotoxicity. In this article, we provide perspective on challenges encountered in and future potential of clinical development of a triapine-cisplatin-radiation combination for patients with regionally advanced cervical cancer. New trial results and review presented here suggest that a triapine-cisplatin-radiation combination may offer molecular cell cycle target control to maximize damage in cancers and to minimize injury to normal cells. A randomized trial now accrues patients with regionally advanced stage cervical cancer to evaluate triapine's contribution to clinical benefit after cisplatin-radiation (clinicaltrials.gov, NCT02466971).
