Early Stage Ovarian Cancer

Abstract Background Laparoscopy has been widely used for patients with early-stage epithelial ovarian cancer (eEOC). However, there is limited evidence regarding whether survival outcomes of laparoscopy are equivalent to those of laparotomy among patients with eEOC. The result of survival outcomes of laparoscopy is still controversial. The aim of this meta-analysis is to analyze the survival outcomes of laparoscopy versus laparotomy in the treatment of eEOC. Methods According to the keywords, Pubmed, Embase, Cochrane Library and Clinicaltrials.gov were searched for studies from January 1994 to January 2021. Studies comparing the efficacy and safety of laparoscopy versus laparotomy for patients with eEOC were assessed for eligibility. Only studies including outcomes of overall survival (OS) were enrolled. The meta-analysis was performed using Stata software (Version 12.0) and Review Manager (Version 5.2). Results A total of 6 retrospective non-random studies were included in this meta-analysis. The pooled results indicated that there was no difference between two approaches for patients with eEOC in OS (HR = 0.6, P = 0.446), progression-free survival (PFS) (HR = 0.6, P = 0.137) and upstaging rate (OR = 1.18, P = 0.54). But the recurrence rate of laparoscopic surgery was lower than that of laparotomic surgery (OR = 0.48, P = 0.008). Conclusions Laparoscopy and laparotomy appear to provide comparable overall survival and progression-free survival outcomes for patients with eEOC. Further high-quality studies are needed to enhance this statement.

Objective Characterize the survival impact of smoking on HPV-related (human papillomavirus) oropharyngeal squamous cell carcinoma. Data Sources Articles from 2000 to 2019 in the PubMed, Embase, and Cochrane Library databases were systematically reviewed for content and inclusion/exclusion criteria. Review Methods Two reviewers independently analyzed the databases for eligibility and quality of the articles. Demographic data, smoking history, and survival outcomes were recorded. Hazard ratios and 95% CIs were collectively analyzed through a random effects meta-analysis model. Results Fifteen articles were included in the meta-analysis for overall survival, disease-specific survival, disease-free survival, progression-free survival, and locoregional recurrence outcomes. The overall survival hazard ratio was 2.4 for ever having smoked (95% CI, 1.4-4.0; P = .0006, I2 = .384) and 3.2 for current smoking (95% CI, 2.2-4.6; P < .0001, I2 = 0). The hazard ratio for disease-specific survival in current smokers was 6.3 (95% CI, 1.3-29.3; P = .0194, I2 = 0). Ever smoking had a larger impact on overall survival and disease-specific survival than the 10–pack year smoking threshold. Conclusion Smoking negatively affects survival in patients with HPV-related oropharyngeal carcinoma across all outcomes. Current smoking during treatment is associated with the greatest reduction in survival, possibly secondary to diminished radiation therapy efficacy.

e17105 Background: Intraperitoneal (IP) chemotherapy has been shown to prolong overall survival in optimally debulked stage III ovarian cancer in randomized trials. In British Columbia, we extrapolated this benefit of IP chemotherapy to early stage HGSC patients for the last 10 years, as these patients are optimally debulked at surgery but still have a high rate of recurrence. We conducted a retrospective study of clinical outcomes associated with IP/IV chemotherapy compared to IV chemotherapy for optimally debulked stage I HGSC cases. Methods: This was a retrospective cohort study of women with stages IA-IC HGSC who had primary surgery between 2007-2015, and received either IV or IP/IV chemotherapy post-operatively. We compared progression-free survival (PFS) and overall survival (OS) outcomes between these 2 groups. Kaplan-Meier method evaluated chemotherapy delivery route with progression free survival (PFS) and overall survival (OS), using the statistical program R. Results: We identified 99 patients; 80 (81%) received IV chemotherapy and 19 (19%) received IP/IV chemotherapy. Among IP/IV cohort, 2/19 (11%) discontinued IP therapy during treatment due to abdominal pain at IP port site or hypersensitivity reaction to IV paclitaxel. 5-year PFS was 88.4% (74.5-100%) and 69.7% (58.7-82.7%) among the IP/IV and IV cohorts, respectively (p = 0.549). There was a trend for higher 5-year OS for the IP/IV group; however, this did not reach statistical significance (100% vs. 71.4%; p = 0.182). Conclusions: In our study, IP/IV chemotherapy for stage I HGSC patients was associated with a trend for higher 5-year PFS and OS compared to IV chemotherapy. This observation warrants further prospective investigation.

Background: This meta-analysis explored the correlation between the C-reactive protein to albumin ratio (CAR) and survival outcomes and clinicopathological characteristics in patients with pancreatic cancer. Methods: PubMed, Embase, Web of Science, and Cochrane Library databases were comprehensively searched through October 17, 2019. Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were used to evaluate the association between CAR and overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS) in pancreatic cancer. Results: The meta-analysis included 11 studies comprising 2271 patients. The pooled results showed that a high CAR was predictive of worse OS (HR = 1.84, 95% CI = 1.65-2.06, P < .001), PFS (HR = 1.53, 95% CI = 1.27-1.85, P < .001), and DFS (HR = 1.77, 95% CI = 1.30-2.41, P < .001). An elevated CAR was also associated with male sex (OR = 1.38, 95% CI = 1.10-1.74, P = .006). Conclusion: Elevated pretreatment CAR effectively predicts inferior survival outcomes in patients with pancreatic cancer and may be a powerful prognostic indicator for these patients.

ObjectiveThe aim of this study was to conduct a meta-analysis to establish the prognostic value of platelet-to-lymphocyte ratio in cervical cancer.MethodsWe conducted a search in Medline and Embase datasets for articles published until May 1, 2018 to perform a meta-analysis to establish the prognostic value of platelet-to-lymphocyte ratio in cervical cancer. The primary survival outcomes were overall survival and progression-free survival. The pooled hazard ratios (HRs) and 95% confidence intervals (95% CIs) were combined to calculate overall effects. Cochran’s Q test and Higgins’ I2statistics were employed to estimate the heterogeneity. In addition, the subgroup analysis, sensitivity analysis, and meta-regression were performed to identify the source of heterogeneity. Egger’s linear regression test and Begg’s funnel plot and the trim and fill methods were employed to evaluate the publication bias.ResultsA total of 2616 patients from eight studies were enrolled in the meta-analysis. Significant association was observed between elevated platelet-to-lymphocyte ratio and a worse overall survival, with a combined HR of 1.49 (95% CI 1.24 to 1.79, I2=32.8%). Elevated platelet-to-lymphocyte ratio was significantly associated with a worse progression-free survival, with a combined HR of 1.65 (95% CI 1.17 to 2.33, I2= 49.4%). Subsequently, sensitivity analysis, subgroup analysis, and meta-regression model containing six predominant factors were applied to trace the origin of heterogeneity. However, no significant factors or studies were explored as the potential source of heterogeneity.ConclusionElevated pre-treatment platelet-to-lymphocyte ratio may be an adverse prognostic factor for overall survival and progression-free survival in patients with cervical cancer. Further investigations are warranted to determine the exact mechanism by which platelet-to-lymphocyte ratio impacts survival outcomes in cervical cancer.

In solid malignancies, the glucocorticoid receptor (GR) signalling axis is associated with tumour progression and GR antagonists are in clinical development. Therefore, GR expression may be a useful potential prognostic or predictive biomarker for GR antagonist therapy in cancer. The aim of this review is to investigate if GR expression in tumours is predictive of overall survival or progression free survival. Twenty-five studies were identified through systematic searches of three databases and a meta-analysis conducted using a random effects model, quantifying statistical heterogeneity. Subgroup analysis was conducted for cancer types and publication bias was assessed via funnel plots. There was high heterogeneity in meta-analysis of the studies in all cancer types, which found no association between high GR expression with overall survival (pooled unadjusted HR 1.16, 95% CI (0.89–1.50), n = 2814; pooled adjusted HR 1.02, 95% CI (0.77–1.37), n = 2355) or progression-free survival (pooled unadjusted HR 1.12, 95% CI (0.88–1.42), n = 3365; pooled adjusted HR 1.04, 95% CI (0.6–1.81), n = 582) across all cancer types. However, subgroup meta-analyses showed that high GR expression in gynaecological cancers (endometrial and ovarian) (unadjusted HR 1.83, 95% CI (1.31–2.56), n = 664) and early stage, untreated triple negative breast cancers (TNBCs) (unadjusted HR 1.73, 95% CI (1.35–2.23), n = 687) is associated with disease progression. GR expression in late stage, chemotherapy treated TNBC was not prognostic (unadjusted HR 0.76, 95% CI (0.44, 1.32), n = 287). In conclusion, high GR expression is associated with an increased risk of disease progression in gynaecological and early stage, untreated TNBC. Additional studies are required to elucidate the tumour specific function of the GR receptor in order to ensure GR antagonists target the correct patient groups.

AbstractTreatment outcomes between FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) and GNP (gemcitabine with albumin-bound paclitaxel) as first-line chemotherapy regimens for metastatic pancreatic cancer (PC) were assessed according to ethnic groups categorized as Western or Asian subgroups. PubMed, EMBASE, and Cochrane library were searched. Thirteen studies were eligible in this meta-analysis. Overall survival was not significantly different between FOLFIRINOX and GNP (HR 1.00, 95% CI 0.83–1.20, P = 0.990). However, the Western subgroup showed a higher survival benefit for FOLFIRINOX over GNP (HR 0.84, 95% CI 0.74–0.95, P = 0.006) whereas the Asian subgroup showed the survival benefit for GNP over FOLFIRINOX (HR 1.29, 95% CI 1.03–1.60, P = 0.030). Progression free survival was not significantly different between the two regimens in the Western subgroup (HR 1.01, 95% CI 0.84–1.20, P = 0.950) and the Asian subgroup (HR 1.13, 95% CI 0.97–1.33, P = 0.110). Occurrence of febrile neutropenia was significantly higher in FOLFIRINOX at both ethnic subgroups; however, that of peripheral neuropathy was significantly higher only in GNP of the Asian subgroup. Therefore, pharmacoethnicity might be a factor worth considering when deciding on a frontline chemotherapeutic regimen although the overall survival was not significantly different between FOLFIRINOX and GNP for metastatic PCs.

Treatment-related adverse events (AEs) can obfuscate the maintenance of a conventional schedule of sunitinib in patients with metastatic renal cell carcinoma. Accordingly, alternative schedules seeking to improve the safety profile of sunitinib have been tested. Recently, two meta-analyses similarly described improved safety profiles favoring a two weeks on and one week off (2/1) schedule, but with conflicting results for survival outcomes. Therefore, we conducted an updated systematic review and meta-analysis, including all recently published studies and using complementary statistical methods. Endpoints included progression-free survival, overall survival, and AEs of 15 types. Eleven articles were included in this meta-analysis. Using adjusted findings, we noted statistically better results in progression-free survival (hazard ratio, 0.58; 95% confidence interval, 0.39–0.84; p = 0.005), but no difference in overall survival (hazard ratio, 0.66; 95% confidence interval, 0.42–1.04; p = 0.08). Moreover, the 2/1 schedule was beneficial for reducing the incidence of several AEs. Conclusively, our meta-analysis suggests that the 2/1 schedule holds promise as an alternative means of reducing AEs and maintaining patient quality of life. While the survival outcomes of the 2/1 schedule seem also to be favorable, the level of evidence for this was low, and the interpretation of these findings should warrant caution. Large scale randomized trials are needed to support these results.

Background Open resection (OR) of sinonasal mucosal melanoma (SNM) traditionally has been the gold standard for treatment. However, endoscopic resection (ER) has recently become a surgical alternative. The aim of this study was to compare survival outcomes between OR and ER of SNM. Methods A literature search encompassing PubMed, Embase, Cochrane Library, Web of Science, ClinicalTrials.gov, and Google Scholar was performed. Two reviewers independently screened for original studies comparing survival outcomes between OR and ER for SNM. Data were systematically collected on study design, patient demographics, outcomes, and level of evidence. Quality assessment was performed using the Newcastle-Ottawa scale (NOS). Meta-analysis of overall survival and disease-free survival was performed using random-effects models. Results The initial search yielded 2078 abstracts, of which 9 cohort studies were included for a total of 510 patients from 6 different countries. The average quality of all included studies using the NOS was 7.7 stars. Six out of 7 studies reported no differences in the stages of SNM between patients receiving ER versus OR. Overall survival was longer in the ER group versus OR group (hazard ratio [HR]: 0.68, 95% confidence interval [CI]: 0.49–0.95). There was no significant difference in disease-free survival between groups (HR: 0.59, 95% CI: 0.28–1.25). Conclusion Based on the available literature, an endoscopic approach for SNM resection has survival outcomes that are similar or greater compared to an open approach.

Early Stage Ovarian Cancer

Epithelial ovarian cancer stem cells (EOC stem cells) have been associated with recurrence and chemoresistance. CD44 and CK18 are highly expressed in cancer stem cells and function as tools for their identification and characterization. We investigated the association between the number of CD44+ EOC stem cells in ovarian cancer tumors and progression-free survival. EOC stem cells exist as clusters located close to the stroma forming the cancer stem cell “niche”. 17.1% of the samples reveled high number of CD44+ EOC stem cells (>20% positive cells). In addition, the number of CD44+ EOC stem cells was significantly higher in patients with early-stage ovarian cancer (FIGO I/II), and it was associated with shorter progression-free survival (P=0.026). This study suggests that quantification of the number of EOC stem cells in the tumor can be used as a predictor of disease and could be applied for treatment selection in early-stage ovarian cancer.
