Class of 2017 Abstract / Objectives: The specific aims of this project were to evaluate the incidence of carboplatin HSR in patients with the BRCA1 or BRCA2 mutations compared to those without these mutations. Secondary objectives were to identify carboplatin cycles where reactions occurred, grade of reaction, and treatment outcomes. Methods: This retrospective chart review included 167 ovarian, fallopian tube, and primary peritoneal cancer patients at the University of Arizona Cancer Center who underwent a regimen with carboplatin from 2013-2015. Results: 126 out of 167 patients were analyzed. HSR occurred in 4 patients with BRCA mutations, and in 9 patients without mutations, though incidence was not significant with respect to the groups (3.1% versus 17.4%, P=0.5291). Overall, there were 11 grade 1 reactions, 14 grade 2 reactions, and 16 grade 3 reactions to carboplatin. Conclusions: Presence of a BRCA1/2 mutation was not associated with a higher incidence of HSR in carboplatin. More studies are needed to clarify the impact of BRCA mutations on developing carboplatin HSR.

BACKGROUND:Recent advances suggest fallopian tube as the main cellular source for women's pelvic serous carcinoma (PSC). In addition to TP53 mutations, many other genetic changes are involved in pelvic serous carcinogenesis. IMP3 is an oncofetal protein which has recently been observed to be overexpressed in benign-looking tubal epithelia. Such findings prompted us to examine the relationship between IMP3 over-expression, patient age and the likelihood of development of PSC.METHODS:Fallopian tubes from three groups (low-risk, high-risk, and PSC) of patients with matched ages were studied. Age was recorded in 10years intervals ranging from age 20 to older than 80. The number of IMP3 signatures (defined by 10 or more tubal secretory cells stained positively and continuously in benign appearing tubal mucosa) from both tubal fimbria and ampulla segments was measured. The data was analyzed by standard contingency table and Poisson distribution methods after age adjustment. IMP3 overexpression was also examined in serous tubal intraepithelial carcinoma and PSC.RESULTS:The positive IMP3-stained cells are mainly tubal secretory cells. The absolute number of tubal IMP3 signatures increased significantly within each age group. Age remained a significant risk factor for serous neoplasia after age adjustment. IMP3 signatures were more frequent in the patients of both high-risk and PSC groups. The presence of IMP3 signatures in tubal mucosa was significantly associated with tubal or pelvic serous carcinogenesis (p<0.001).CONCLUSIONS:The findings suggest that tubal secretory cells with IMP3 signatures showing growth advantage could potentially serve as a latent precancer biomarker for tubal or pelvic serous carcinomas in women.

Anatomicamente e funcionalmente, o oviduto é dividido em três regiões principais: infundíbulo, ampola e istmo. O oócito e o espermatozoide entram nos lados opostos do oviduto, respectivamente no infundíbulo e istmo, e são transportados até a ampola, local onde ocorre a fertilização. O sucesso reprodutivo está diretamente ligado a temporização apropriada do transporte dos gametas ao local da fertilização, bem como, a precisão no tempo de transporte do embrião até o útero, para a aquisição da capacidade de implantação. A coordenação e regulação das funções do oviduto são complexas e estão sob efeitos endócrinos, parácrinos e autócrinos, os quais alteram temporalmente e espacialmente a transcrição e tradução de diversos fatores. Diante disso, o presente trabalho visou avaliar o efeito de biotecnologias reprodutivas, especificamente da superestimulação ovariana, bem como de características genéticas e fisiológicas reprodutivas no perfil transcricional de diversos fatores no oviduto bovino. Para tanto, foram avaliados os efeitos da indução de múltiplas ovulações em vacas da raça Nelore (dados apresentados no primeiro manuscrito), bem como os efeitos da influência da seleção genética de animais com alta contagem folicular em novilhas da raça Nelore e Aberdeen Angus, no período inicial pós ovulação (dados apresentados no segundo manuscrito), na expressão de genes relacionados ao transporte de gametas e fertilização.

Anatomically and functionally, the oviduct is divided in three regions: infundibulum, ampulla and isthmus. The oocyte and the sperm enter in opposite sides of the oviduct, respectively infundibulum and isthmus, and are transported to the fertilization site, the ampulla. Reproductive success is directly related to appropriate timing of gamete transport to the fertilization site, as well as a precise time of embryo transport to the uterus, to obtain the capacity of implantation. The coordination and regulation of oviductal functions are complex and under endocrine, paracrine and autocrine effects, which temporally and spatially alter the transcription and translation of several factors. Therefore, this study aimed to evaluate the effect of reproductive biotechnologies, specifically ovarian superstimulation, as well as genetic and physiological reproductive characteristics in the transcriptional profile of several factors in the bovine oviduct. To do so, we evaluated the effects of inducing multiple ovulation in Nelore cows (data presented in the first manuscript), and the effects of the influence of genetic selection of animals with high follicle count in Nellore and Aberdeen Angus heifers, in the initial period post-ovulation (data presented in the second manuscript), in gene expression related to gametes transport and fertilization. The results demonstrated that ovarian superstimulation modulates the expression of some genes related to oviductal contractility in Nelore cows and ovulation is the main factor responsible for transcriptional control in bovine oviduct, with less or no impact of breed and ovarian follicle count / Mestre

Prophylactic salpingo-oophorectomy, the preventive removal of the ovaries and fallopian tubes, is recommended to women who carry a BRCA1 or BRCA2 mutation in order to reduce the risk of breast, ovarian and fallopian tube cancer. The short and long term health and quality of life effects of this procedure are not well understood. We examined the actual and perceived reduction in cancer risk associated with this surgery. The impact of prophylactic salpingo-oophorectomy on health-related quality of life, psychological distress, cancer worry, menopausal symptoms, and sexual function during the year following surgery was also evaluated. In our prospective study, prophylactic salpingo-oophorectomy was associated with an 80% reduction in ovarian and fallopian tube cancer risk. The residual risk for primary peritoneal cancer was 0.2% per year or 4.3% at 20 years after salpingo-oophorectomy. Most women accurately perceived their risk of breast cancer. However, the risk for ovarian cancer was overestimated, particularly by women who carry a BRCA2 mutation. Physical and mental health-related quality of life did not decrease in the year following surgery; and psychological distress was similar to levels experienced by the general population. Most women were significantly less worried about cancer after the surgery, however, a subset of women continued to experience significant cancer specific distress after prophylactic salpingo-oophorectomy. Women who underwent prophylactic salpingo-oophorectomy when premenopausal experienced a significant worsening of vasomotor symptoms and a decline in sexual functioning. Hormone replacement therapy mitigated these symptoms, but not to pre-surgical levels. Dyspareunia was somewhat alleviated by hormone replacement therapy, however, the decrease in sexual pleasure was not. Satisfaction with the decision to undergo prophylactic salpingo-oophorectomy was high regardless of these symptoms. These studies will provide women who are considering prophylactic salpingo-oophorectomy with information about the reduction in cancer risk associated with the surgery and the possible effects experienced during the year following surgery.

Optical imaging methods have the potential to detect ovarian cancer at an early, curable stage. Optical imaging has the disadvantage that high resolution techniques require access to the tissue of interest, but miniature endoscopes that traverse the natural orifice of the reproductive tract, or access the ovaries and fallopian tubes through a small incision in the vagina wall, can provide a minimally-invasive solution. We have imaged both rodent and human ovaries and fallopian tubes with a variety of endoscope-compatible modalities. The recent development of fiber-coupled femtosecond lasers will enable endoscopic multiphoton microscopy (MPM). We demonstrated two-and three-photon excited fluorescence (2PEF, 3PEF), and second-and third-harmonic generation microscopy (SHG, THG) in human ovarian and fallopian tube tissue. A study was undertaken to understand the mechanisms of contrast in these images. Six patients (normal, cystadenoma, and ovarian adenocarcinoma) provided ovarian and fallopian tube biopsies. The tissue was imaged with three-dimensional optical coherence tomography, multiphoton microscopy, and frozen for histological sectioning. Tissue sections were stained with hematoxylin and eosin, Masson's trichrome, and Sudan black. Approximately 1 mu m resolution images were obtained with an excitation source at 1550 nm. 2PEF signal was absent. SHG signal was mainly from collagen. 3PEF and THG signal came from a variety of sources, including a strong signal from fatty connective tissue and red blood cells. Adenocarcinoma was characterized by loss of SHG signal, whereas cystic abnormalities showed strong SHG. There was limited overlap of two-and three-photon signals, suggesting that three-photon imaging can provide additional information for early diagnosis of ovarian cancer.
