Ovarian cancer, a term that encompasses ovarian, fallopian, and peritoneal cancers, is the leading cause of gynecologic cancer mortality. To improve patient outcomes, the field is currently focused on defining the mechanisms of cancer formation and spread, early diagnosis and prevention, and developing novel therapeutic options. This review summarizes recent advances in these areas.

Early diagnosis and intervention are some of the longstanding challenges associated with ovarian cancer, which is the leading cause of gynecologic cancer mortality. While the majority of patients who present with advanced stage disease at time of diagnosis will initially respond to traditional combination platinum and taxane-based chemotherapy in conjunction with cytoreductive surgery, approximately 70% will ultimately recur due to chemoresistance within the first two years. Intratumor heterogeneity is proposed to be a leading factor in the development of chemoresistance and resultant poorer outcomes for those with recurrent or advanced stage disease. Both inherent and acquired mechanisms of chemoresistance are postulated to be a result of alterations in gene expression, also known as epigenetic modifications. Therefore, epigenetic therapy is a pivotal avenue which allows for reversal of chemoresistance in cancer through the targeting of aberrant mutations. In this chapter, we discuss how these epigenetic modifications prove to be promising targets in cancer therapy leading to heightened drug sensitivity and improved patient survival outcomes.

Dupuytren’s disease (DD) is a common fibrotic disorder of the hand and can significantly impair hand function. Although the exact pathogenesis of this disorder remains to be elucidated, immunological, genetic and cellular factors likely interact. In this review, we summarise recent advances in the understanding of DD pathogenesis and look to the future for potential novel therapeutic targets. In addition, we discuss the therapeutic options in DD with a focus on the need for more rigorous evidence to allow a meaningful comparison of different treatment modalities.

5571 Background: Mucinous ovarian carcinoma (MOC) is a rare subtype of epithelial ovarian cancer that responds poorly to ovarian chemotherapies and has an unknown etiology. It is diagnostically challenging and can be confused with metastases from gastro-intestinal tract primaries. The GAMuT study is a multi-national effort to understand molecular drivers and cell of origin of this rare tumour, including identification of a genetic progression model and novel therapeutic options. Methods: We performed RNAseq (n = 67), exome sequencing (n = 61), SNP arrays (n = 67) and whole genome sequencing (n = 5) on MOC and precursor lesions. A subset of ~500 genes was further evaluated by targeted sequencing, including 129 MOC, 23 borderline mucinous tumours (non-invasive) and 23 extra-ovarian mucinous metastases. Immunohistochemistry data was collected for CK7, CK20, ER, PAX8, p53 and HER2 (n = 162-256). Extensive pathology review was performed and associated clinical data obtained. Results: Comparison with TCGA and other data sets showed that MOC are distinct from mucinous tumours from other organs, including colorectal, appendiceal and gastric cancers. Our data supports a clear genetic progression model from benign and borderline precursors to both low- and high-grade MOC. TP53 mutation, ERBB2 amplification and increasing copy number changes were key events associated with progression to invasive disease, including a novel amplicon on 9p13. Copy number aberration burden was significantly associated with poor survival. We identified several recurrent mutational events suggesting utility of an existing targeted therapy, including ERBB2 amplification (26%), ERBB3 mutation (4%) and BRAF mutation (9%). MOC could be included in clinical trials for novel agents targeting TP53 missense mutation (46%), RNF43 mutation (12%), PIK3CA mutation (8%) and KRAS/ NRAS mutations (66%). Other frequent events included CDKN2A inactivation (57%), ARID1A mutation (9%) and TP53 inactivating mutations (15%). Conclusions: MOC of any grade can derive from a primary ovarian tumour precursor, and is distinct from extra-ovarian metastases. MOC is genetically diverse and advanced disease should be assessed for targetable mutations which may provide novel therapeutic options.

Significance Statement Pharyngeal fistulas to the cervical spine resulting in vertebral osteomyelitis are a rare, yet clinically important, complication of total laryngectomy performed in conjunction with chemoradiotherapy or radiation therapy. This complication is likely underdiagnosed and can have a high mortality rate. It is very important that clinicians are aware of this complication as early diagnosis and management may improve patient outcomes.

Abstract Congenital oesophageal diverticulum is incredibly rare and has not commonly been published in the literature. Oesophageal diverticulum can be asymptomatic; however, symptoms such as dysphagia, regurgitation and chest discomfort may be present. We describe the case of a paediatric patient presenting with biphasic stridor, respiratory distress and cyanosis at birth, who was found to have a supraglottic cyst and later the presence of an oesophageal diverticulum shown on ultrasound imaging. There has been one other case reported in the literature of an oesophageal diverticulum presenting with stridor, and we therefore believe this is one of only two cases to illustrate this atypical presentation of congenital oesophageal diverticulum. It highlights the importance of a meticulous multidisciplinary team approach to patient care, as well as conducting appropriate investigations to aid early diagnosis to improve patient outcomes.

Ovarian cancer is the major cause of gynecologic cancer-related mortality. Regardless of outstanding advances, which have been made for improving the prognosis, diagnosis, and treatment of ovarian cancer, the majority of the patients will die of the disease. Late-stage diagnosis and the occurrence of recurrent cancer after treatment are the most important causes of the high mortality rate observed in ovarian cancer patients. Unraveling the molecular mechanisms involved in the pathogenesis of ovarian cancer may help find new biomarkers and therapeutic targets for ovarian cancer. MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression, mostly at the posttranscriptional stage, through binding to mRNA targets and inducing translational repression or degradation of target via the RNA-induced silencing complex. Over the last two decades, the role of miRNAs in the pathogenesis of various human cancers, including ovarian cancer, has been documented in multiple studies. Consequently, these small RNAs could be considered as reliable markers for prognosis and early diagnosis. Furthermore, given the function of miRNAs in various cellular pathways, including cell survival and differentiation, targeting miRNAs could be an interesting approach for the treatment of human cancers. Here, we review our current understanding of the most updated role of the important dysregulation of miRNAs and their roles in the progression and metastasis of ovarian cancer. Furthermore, we meticulously discuss the significance of miRNAs as prognostic and diagnostic markers. Lastly, we mention the opportunities and the efforts made for targeting ovarian cancer through inhibition and/or stimulation of the miRNAs.

AbstractIn the context of hydrocephalus, there are a multitude of therapeutic options that can be explored in order to improve patient outcomes. Although the peritoneum is the current elected clinical solution, various receptacles have been utilized when experiencing contraindications. Along with the ventriculoatrial or ventriculopleural, the ventriculocholecystic shunt was also described as an alternative. In order to make a decision on a place for drainage, the surgeon must be knowledgeable on details from modern literature. The main target of this review was to summarize the currently available information on this topic and assess the status of the gallbladder as a viable option for cerebrospinal fluid diversion.
