Electronic records, registries, and the development of big data : crowd-sourcing quality toward knowledge.

Despite many perceived advances in treatment over the past few decades, cancer continues to present a significant health burden, particularly to the aging US population. Forces including shrinking funding mechanisms, cost and quality concerns, as well as disappointing clinical outcomes have driven a surge of recent efforts into utilizing the technological innovation that has permeated other industries by leveraging large and complex data sets, so called big data. In this review, we will review some of the history of oncology data collection, including the earliest data registries, as well as explore the future directions of this new brand of research while highlighting some of the more recent and promising efforts to harness the power of the electronic health record and the multitude of data co-located there, in an effort to improve individualized cancer-related outcomes in rapid real time

The role of neoadjuvant chemotherapy in the management of patients with advanced stage ovarian cancer: Survey results from members of the society of gynecologic oncologists, a 5-year follow-up

• NACT use among SGO members for ovarian cancer is explored given recent trials. • Fewer SGO members feel they can't predict optimal cytoreduction pre-operatively. • Laparoscopy use has increased both for diagnosis and treatment of ovarian cancer. • Very high optimal cytoreduction rates are reported from SGO members. • Despite recent studies, SGO members don't regularly treat patients with NACT/ID

Society of Gynecologic Oncology Clinical Outcomes Registry: From small beginnings come great things.

OBJECTIVE: Clinical registries within medical societies have demonstrated the capacity to promote quality improvement. Opportunities for well-designed data repositories could yield reliable national standards for informing reimbursement, determining adherence to care guidelines, maintaining board certification, and developing bundled payment models. Looking to the future, we set out to develop a gynecologic cancer registry serving the members of the Society of Gynecologic Oncology (SGO). METHODS: The SGO Clinical Outcomes Registry (COR) initiated a web-based data entry platform as a foray into developing a functional registry, compiling data elements specific to gynecologic oncology. Endometrial and ovarian cancer patients began enrollment in early 2014. Within one year, 19 sites were participating with the addition of cervical cancer patients in January 2015. RESULTS: To date, \u3e6500 patients are currently entered from 29 sites, and the COR is being queried to address topics of quality improvement, disparities, and cancer outcomes. CONCLUSIONS: The SGO COR has proven the feasibility of developing a functional gynecologic cancer registry, with high uptake, rapid accrual, and ability to investigate topics of quality and outcome using the COR

TP53 Sequencing and p53 Immunohistochemistry Predict Outcomes When Bevacizumab Is Added to Frontline Chemotherapy in Endometrial Cancer: An NRG Oncology/Gynecologic Oncology Group Study.

PURPOSE: The status of p53 in a tumor can be inferred by next-generation sequencing (NGS) or by immunohistochemistry (IHC). We examined the association between p53 IHC and sequence and whether p53 IHC alone, or integrated with TP53 NGS, predicts the outcome. METHODS: From GOG-86P, a randomized phase II study of chemotherapy combined with either bevacizumab or temsirolimus in advanced endometrial cancer, 213 cases had p53 protein expression data measured by IHC and TP53 NGS data. An analysis was designed to integrate p53 expression by IHC with the presence or absence of a TP53 mutation. These variables were further correlated with progression-free survival (PFS) and overall survival (OS) in the chemotherapy plus bevacizumab arms versus the chemotherapy plus temsirolimus arm. RESULTS: In the analysis of p53 IHC, the most striking treatment effect favoring bevacizumab was in cases where p53 was overexpressed (PFS hazard ratio [HR]: 0.46, 95% CI, 0.26 to 0.88; OS HR: 0.31, 95% CI, 0.16 to 0.62). On integrated analysis, patients with TP53 missense mutations and p53 protein overexpression had a similar treatment effect on PFS (HR: 0.41, 95% CI, 0.22 to 0.83) and OS (HR: 0.28, 95% CI, 0.14 to 0.59) favoring bevacizumab plus chemotherapy relative to temsirolimus plus chemotherapy. Concordance between TP53 NGS and p53 IHC was 88%. Concordance was 92% when cases with TP53 mutations and POLE mutations or mismatch repair deficiency were removed. CONCLUSION: IHC for p53 alone or when integrated with sequencing for TP53 identifies a specific, high-risk tumor genotype/phenotype for which bevacizumab is particularly beneficial in improving outcomes when combined with chemotherapy

Mutated p53 portends improvement in outcomes when bevacizumab is combined with chemotherapy in advanced/recurrent endometrial cancer: An NRG Oncology study

BackgroundSuccessfully combining targeted agents with chemotherapy is an important future goal for cancer therapy. However, an improvement in patient outcomes requires an enhanced understanding of the tumor biomarkers that predict for drug sensitivity. NRG Oncology/Gynecologic Oncology Group (GOG) Study GOG-86P was one of the first attempts to combine targeted agents (bevacizumab or temsirolimus) with chemotherapy in patients with advanced endometrial cancer. Herein we performed exploratory analyses to examine the relationship between mutations in TP53, the most commonly mutated gene in cancer, with outcomes on GOG-86P.MethodsTP53 mutational status was determined and correlated with progression-free survival (PFS) and overall survival (OS) on GOG-86P.ResultsMutations in TP53 were associated with improved PFS and OS for patients that received bevacizumab as compared to temsirolimus (PFS: HR 0.48, 95% CI 0.31, 0.75; OS: HR: 0.61, 95% CI 0.38, 0.98). By contrast, there was no statistically significant difference in PFS or OS between arms for cases with WT TP53.ConclusionsThis exploratory study suggests that combining chemotherapy with bevacizumab, but not temsirolimus, may enhance PFS and OS for patients whose tumors harbor mutant p53. These data set the stage for larger clinical studies evaluating the potential of TP53 mutational status as a biomarker to guide choice of treatment for endometrial cancer patients.
