Objective: Vaginal pH has been suggested to be one of the causative factors, responsible for variation in prostaglandin efficacy for induction of labour. The purpose of this study was to analyse the effect of vaginal douching with normal saline before insertion of dinoprostone vaginal insert for induction of labour.
Methods: This randomised controlled study was done in the Department of Obstetrics and Gynaecology for a period of 1 year.
Background: Determinates of tumor treating fields (TTFields) usage in patients receiving combined modality therapy for primary IDH wild-type glioblastoma are currently unknown.
Methods: Ninety-one patients underwent maximal debulking surgical resection, completed external beam radiotherapy with concurrent Temozolomide (TMZ), and initiated adjuvant TMZ with or without TTFields. We performed a retrospective analysis of patient, tumor, and treatment-related factors that affected TTFields usage.
Background: The genomic and overall biologic landscape of glioblastoma (GB) has become clearer over the past 2 decades, as predictive and prognostic biomarkers of both de novo and transformed forms of GB have been identified. The oral chemotherapeutic agent temozolomide (TMZ) has been integral to standard-of-care treatment for nearly 2 decades. More recently, the use of non-pharmacologic interventions, such as application of alternating electric fields, called Tumor-Treating Fields (TTFields), has emerged as a complementary treatment option that increases overall survival (OS) in patients with newly diagnosed GB.

A retrospective study of 109 glioblastoma patients was performed to determine the optimal cutoff point for MGMT methylation status. Receiver operating characteristic (ROC) analysis revealed 21% as the optimal cutoff (sensitivity: 68%; specificity: 59%) for MGMT methylation corresponding with the highest likelihood ratio of 1.

Although the same approach to treatment is typically adopted for GS and GB, there remains some debate as to whether GS should be considered a discrete pathological entity. Differences between these tumors have not been clearly established at the molecular level.

Our objective was to elucidate mutational profiles from primary versus metastatic sites from advanced cancer patients to guide rational therapy. All phase I patients ( = 203) with advanced cancer were profiled by commercially available NGS platforms.

The involvement of an interdisciplinary team, including neurosurgeons, radiation therapists, oncologists, neurologists, and neuroradiologists, is a key factor in the appropriate management of CNS cancers. Integrated histopathologic and molecular characterization of brain tumors such as gliomas should be standard practice.

Materials And Methods: To genetically characterize and ascertain if the majority of PCNSL patients may potentially benefit from immune checkpoint inhibitors, we profiled 48 subjects with PCNSL from 2013 to 2018 with (1) next-generation sequencing to detect mutations, gene amplifications, and microsatellite instability (MSI); (2) RNA sequencing to detect gene fusions; and (3) immunohistochemistry to ascertain PD-1 and PD-L1 expression.
Purpose: Tumor mutational burden (TMB) is a developing biomarker in non-small-cell lung cancer (NSCLC). Little is known regarding differences between TMB and sample location, histology, or other biomarkers.
Methods: A total of 3,424 unmatched NSCLC samples, including 2,351 lung adenocarcinomas (LUADs) and 1,073 lung squamous cell carcinomas (LUSCs), underwent profiling, including next-generation sequencing of 592 cancer-related genes, programmed death ligand 1 immunohistochemistry, and TMB.
Tumor-treating fields (TTFields) are a noninvasive antimitotic cancer treatment consisting of low-intensity alternating electric fields delivered to the tumor or tumor bed via externally applied transducer arrays. In multiple in vitro and in vivo cancer cell lines, TTFields therapy inhibits cell proliferation, disrupts cell division, interferes with cell migration and invasion, and reduces DNA repair. Human trials in patients with primary glioblastoma showed an improvement in overall survival, and trials in patients with unresectable malignant pleural mesothelioma showed favorable outcomes compared with historical control.

This first-in-human study investigated the therapeutic use of samalizumab as a CD200 immune checkpoint inhibitor in chronic lymphocytic leukemia (CLL) and multiple myeloma (MM).
Experimental Design: Twenty-three patients with advanced CLL and 3 patients with MM were enrolled in an open-label phase 1 study (NCT00648739).

For many years, the diagnosis and classification of gliomas have been based on histology. Although studies including large populations of patients demonstrated the prognostic value of histologic phenotype, variability in outcomes within histologic groups limited the utility of this system. Nonetheless, histology was the only proven and widely accessible tool available at the time, thus it was used for clinical trial entry criteria, and therefore determined the recommended treatment options.

In an effort to identify new treatment options, we utilized comprehensive genomic profiling to assess the potential for novel therapies in SCCO.
Methods: Patients with SCCO, SCCO-HT (hypercalcemic type), neuroendocrine tumors of the ovary (NET-O), and small cell carcinoma of the lung (SCLC) profiled by Caris Life Sciences between 2007-2015 were identified.
Aim: We evaluated whether tumor genome sequencing to detect the number and type of alterations could be used as a valuable biomarker for judging the potential utility of immune checkpoint inhibitors in patients with advanced cancers.
Materials And Methods: We identified patients with solid tumors who were treated with checkpoint inibitors and had received commercially available next generation sequencing (NGS). Tumors profiled by Caris Life Sciences, Foundation Medicine and Guardant360 between 2013 and 2015.
Small cell carcinoma of the breast is a rare, aggressive form of breast cancer that is associated with extremely poor outcomes [1]. In an effort to identify possible targets for treatment, we utilized comprehensive genomic profiling in small cell carcinoma of the breast. Under an IRB approved protocol, we identified patients with small cell carcinoma of the breast and small cell carcinoma of the lung profiled by Caris Life Sciences between 2007 and 2015.

There are over 13 million cancer survivors in the United States. This is heterogenous group in age, cultural background, and cancer history and also in regards to the natural history of their cancer survivorship. There are "seasons of survivorship" including acute, transitional, extended, permanent, and chronic in which the medical and psychosocial problems and needs of cancer survivors change.
