Abstract Background Cervical cancer is a common malignancy of the female genital tract. Treatment options for cervical cancer patients diagnosed at FIGO (2009) stage IB2 and IIA2 remains controversial. Methods We perform a Bayesian network meta-analysis to directly or indirectly compare various interventions for FIGO (2009) IB2 and IIA2 disease, in order to improve our understand of the optimal treatment strategy for these women. Three databases were searched for articles published between 1971 and 2020. Data on included study characteristics, outcomes, and risk of bias were abstracted by two reviewers. Results Seven thousand four hundred eighty-six articles were identified. Thirteen randomized controlled trials of FIGO (2009) IB2 and IIA2 cervical cancer patients were included in the final analysis. These trials used six different interventions: concomitant chemoradiotherapy (CCRT), radical surgery (RS), radical surgery following chemoradiotherapy (CCRT+RS), neoadjuvant chemotherapy followed by radical surgery (NACT+RS), adjuvant radiotherapy followed by Radical surgery (RT + RS), radiotherapy alone (RT).SUCRA ranking of OS and Relapse identified CCRT+RS and CCRT as the best interventions, respectively. Systematic clustering analysis identified the CCRT group as a unique cluster. Conclusion These data suggest that CCRT may be the best approach for improving the clinical outcome of cervical cancer patients diagnosed at FIGO (2009) stage IB2/IIA2. Phase III randomized trials should be performed in order to robustly assess the relative efficacy of available treatment strategies in this disease context.

6037 Background: GOG-0263 is currently investigating the role of adjuvant chemotherapy (CT) concurrently with radiotherapy (RT) in patients with early stage cervical cancer that underwent radical hysterectomy and pelvic lymphadenectomy harboring intermediate risk features. We used a retrospective database to investigate whether adjuvant chemotherapy significantly influenced overall survival (OS), and whether its effectiveness is influenced by delays in radiotherapy. Methods: All data was obtained from the NCDB (National Cancer Database) and initially contained 115,747 cases of cervical cancer diagnosed between 2004 and 2015. Analyzed patients had early stage disease, received radical hysterectomy with pathologic stage I to IIA, and had intermediate risk features including size greater than 4 cm or lymphovascular invasion. All patients received adjuvant RT with or without CT. Cases with positive margin or nodes, with parametrial extension, or metastasis were excluded. Cases were weighted by inverse probability of treatment (CT) using clinical and socioeconomic variables, and analyzed for OS using multivariate models. Predictors of receiving CT were determined using multivariate logistic regression. Results: The final cohort was 557 patients with median follow-up of 43 months (range, 1.54-143.7). Median survival without CT (n = 244) versus with CT (n = 313) was 42.2 versus 43.9 months (HR 0.81, 95%CI 0.661-0.995, p = 0.045). Median time from diagnosis to RT was 91 days (range, 21-691), and predicted for inferior OS (p = 0.007). No significant interaction existed between RT delay and receipt of CT (p = 0.997). Cases with squamous histology were less likely to receive CT than adenocarcinoma histology (OR 0.345, 95%CI 0.159-0.725, p = 0.006). Conclusions: Poor survival outcomes are observed in patients with early stage cervical cancer harboring intermediate risk features when adjuvant radiotherapy is delayed. This outcome was not corrected by addition of chemotherapy.

Abstract Background : For cervical cancer patients whose tumors display a combination of intermediate risk factors, postoperative radiation with or without adjuvant chemotherapy is suggested for them. However, who should be administered with adjuvant chemotherapy is unknown. The current study was designed to explore the clinical value of squamous cell carcinoma antigen (SCC-Ag) in guiding the use of adjuvant chemotherapy in cervical cancer patients. Methods : A retrospective study of 301 cervical cancer patients treated by surgery and adjuvant treatment from March 2006 to March 2016 was performed. All patients were divided into two groups according to receiving adjuvant chemotherapy or not. Overall survival (OS), disease-free survival (DFS) were compare between patients who did and did not receive adjuvant radiotherapy. Multivariate analysis was employed to detect clinical factors associated with disease-free survival, local recurrence-free survival and distant metastasis-free survival. Results: For patients with high pre-treatment SCC-Ag level, DFS and OS in adjuvant chemo-radiotherapy group were higher than that in adjuvant radiotherapy group. Besides, the rates of distant metastasis were found lower in patients who did receive adjuvant chemotherapy than those who did not. For patients with low pre-treatment SCC-Ag level, the 5-year OS and DFS were similar between groups of adjuvant chemo-radiotherapy and adjuvant radiotherapy. Multivariable analysis indicated adjuvant chemotherapy was independent predictors of DFS and distant metastasis-free survival (DMFS) in patients with high SCC-Ag level. Conclusion: SCC-Ag can serve as an indication for the administration of adjuvant chemotherapy in cervical cancer patients.

Abstract Background To reduce disease recurrence after radical surgery for lung squamous cell carcinomas (SQCCs), accurate prediction of recurrent high-risk patients is required for efficient patient selection for adjuvant chemotherapy. Because treatment modalities for recurrent lung SQCCs are scarce compared to lung adenocarcinomas (ADCs), accurately selecting lung SQCC patients for adjuvant chemotherapy after radical surgery is highly important. Predicting lung cancer recurrence with high objectivity is difficult with conventional histopathological prognostic factors; therefore, identification of a novel predictor is expected to be highly beneficial. Lipid metabolism alterations in cancers are known to contribute to cancer progression. Previously, we found that increased sphingomyelin (SM)(d35:1) in lung ADCs is a candidate for an objective recurrence predictor. However, no lipid predictors for lung SQCC recurrence have been identified to date. This study aims to identify candidate lipid predictors for lung SQCC recurrence after radical surgery. Methods Recurrent (n = 5) and non-recurrent (n = 6) cases of lung SQCC patients who underwent radical surgery were assigned to recurrent and non-recurrent groups, respectively. Extracted lipids from frozen tissue samples of primary lung SQCC were analyzed by liquid chromatography-tandem mass spectrometry. Candidate lipid predictors were screened by comparing the relative expression levels between the recurrent and non-recurrent groups. To compare lipidomic characteristics associated with recurrent SQCCs and ADCs, a meta-analysis combining SQCC (n = 11) and ADC (n = 20) cohorts was conducted. Results Among 1745 screened lipid species, five species were decreased (≤ 0.5 fold change; P < 0.05) and one was increased (≥ 2 fold change; P < 0.05) in the recurrent group. Among the six candidates, the top three final candidates (selected by AUC assessment) were all decreased SM(t34:1) species, showing strong performance in recurrence prediction that is equivalent to that of histopathological prognostic factors. Meta-analysis indicated that decreases in a limited number of SM species were observed in the SQCC cohort as a lipidomic characteristic associated with recurrence, in contrast, significant increases in a broad range of lipids (including SM species) were observed in the ADC cohort. Conclusion We identified decreased SM(t34:1) as a novel candidate predictor for lung SQCC recurrence. Lung SQCCs and ADCs have opposite lipidomic characteristics concerning for recurrence risk.
