  • Ovarian Cancer and Cervical Cancer
    What Every Woman Should Know About Gynecologic Cancer R. Kevin Reynolds, MD The George W. Morley Professor & Chief, Division of Gyn Oncology University of Michigan Ann Arbor, MI What is gynecologic cancer? Cancer is a disease where cells grow and spread without control. Gynecologic cancers begin in the female reproductive organs. The most common gynecologic cancers are endometrial cancer, ovarian cancer and cervical cancer. Less common gynecologic cancers involve vulva, Fallopian tube, uterine wall (sarcoma), vagina, and placenta (pregnancy tissue: molar pregnancy). Ovary Uterus Endometrium Cervix Vagina Vulva What causes endometrial cancer? Endometrial cancer is the most common gynecologic cancer: one out of every 40 women will develop endometrial cancer. It is caused by too much estrogen, a hormone normally present in women. The most common cause of the excess estrogen is being overweight: fat cells actually produce estrogen. Another cause of excess estrogen is medication such as tamoxifen (often prescribed for breast cancer treatment) or some forms of prescribed estrogen hormone therapy (unopposed estrogen). How is endometrial cancer detected? Almost all endometrial cancer is detected when a woman notices vaginal bleeding after her menopause or irregular bleeding before her menopause. If bleeding occurs, a woman should contact her doctor so that appropriate testing can be performed. This usually includes an endometrial biopsy, a brief, slightly crampy test, performed in the office. Fortunately, most endometrial cancers are detected before spread to other parts of the body occurs Is endometrial cancer treatable? Yes! Most women with endometrial cancer will undergo surgery including hysterectomy (removal of the uterus) in addition to removal of ovaries and lymph nodes.

  • About Ovarian Cancer Overview and Types
    cancer.org | 1.800.227.2345 About Ovarian Cancer Overview and Types If you have been diagnosed with ovarian cancer or are worried about it, you likely have a lot of questions. Learning some basics is a good place to start. ● What Is Ovarian Cancer? Research and Statistics See the latest estimates for new cases of ovarian cancer and deaths in the US and what research is currently being done. ● Key Statistics for Ovarian Cancer ● What's New in Ovarian Cancer Research? What Is Ovarian Cancer? Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer and can spread. To learn more about how cancers start and spread, see What Is Cancer?1 Ovarian cancers were previously believed to begin only in the ovaries, but recent evidence suggests that many ovarian cancers may actually start in the cells in the far (distal) end of the fallopian tubes. 1 ____________________________________________________________________________________American Cancer Society cancer.org | 1.800.227.2345 What are the ovaries? Ovaries are reproductive glands found only in females (women). The ovaries produce eggs (ova) for reproduction. The eggs travel from the ovaries through the fallopian tubes into the uterus where the fertilized egg settles in and develops into a fetus. The ovaries are also the main source of the female hormones estrogen and progesterone. One ovary is on each side of the uterus. The ovaries are mainly made up of 3 kinds of cells. Each type of cell can develop into a different type of tumor: ● Epithelial tumors start from the cells that cover the outer surface of the ovary.

  • Photodynamic Therapy for Gynecological Diseases and Breast Cancer
    CancCancerer Biol Med 2012;2012 /9: Vol. 9-17 9 /doi: No. 10.3969/j.issn.2095-3941.2012.1 01.002 9 Review Photodynamic Therapy for Gynecological Diseases and Breast Cancer Natashis Shishkova, Olga Kuznetsova, Temirbolat Berezov Department of Biochemistry, School of Medicine, People’s Friendship University of Russia, Moscow 117198, Russia ABSTRACT Photodynamic therapy (PDT) is a minimally invasive and promising new method in cancer treatment. Cytotoxic reactive oxygen species (ROS) are generated by the tissue-localized non-toxic sensitizer upon illumination and in the presence of oxygen. Thus, selective destruction of a targeted tumor may be achieved. Compared with traditional cancer treatment, PDI has advantages including higher selectivity and lower rate of toxicity. The high degree of selectivity of the proposed method was applied to cancer diagnosis using fluorescence. This article reviews previous studies done on PDT treatment and photodetection of cervical intraepithelial neoplasia, vulvar intraepithelial neoplasia, ovarian and breast cancer, and PDT application in treating non-cancer lesions. The article also highlights the clinical responses to PDT, and discusses the possibility of enhancing treatment efficacy by combination with immunotherapy and targeted therapy. KEY WORDS: photodynamic therapy, photosensitizers, cervical/vulvar intraepithelial neoplasia, ovarian neoplasms, breast neoplasms Introduction frequently used drug in PDT is 5-aminolaevulinic acid (ALA). However, 5-ALA is not a photosensitizer, but a precursor of Photodynamic therapy (PDT) is a mode of therapy used in the endogenous photosensitizer protoporphyrin IX, which is cancer treatment where drug activity is locally controlled by a member of the heme synthesis pathway that occurs in the light (Figure 1).

  • Pembrolizumab in Vaginal and Vulvar Squamous Cell Carcinoma: a Case Series from a Phase II Basket Trial Jefrey A
    www.nature.com/scientificreports OPEN Pembrolizumab in vaginal and vulvar squamous cell carcinoma: a case series from a phase II basket trial Jefrey A. How 1, Amir A. Jazaeri 1, Pamela T. Soliman1, Nicole D. Fleming1, Jing Gong2, Sarina A. Piha‑Paul2, Filip Janku 2, Bettzy Stephen 2 & Aung Naing 2* Vaginal and vulvar squamous cell carcinoma (SCC) are rare tumors that can be challenging to treat in the recurrent or metastatic setting. We present a case series of patients with vaginal or vulvar SCC who were treated with single‑agent pembrolizumab as part of a phase II basket clinical trial to evaluate efcacy and safety. Two cases of recurrent and metastatic vaginal SCC, with multiple prior lines of systemic chemotherapy and radiation, received pembrolizumab. One patient had signifcant reduction (81%) in target tumor lesions prior to treatment discontinuation at cycle 10 following confrmed progression of disease with new metastatic lesions (stable disease by irRECIST criteria). In contrast, the other patient with vaginal SCC discontinued treatment after cycle 3 due to disease progression. Both patients had PD‑L1 positive vaginal tumors and tolerated treatment well. One case of recurrent vulvar SCC with multiple surgical resections and prior progression on systemic carboplatin had a 30% reduction in her target tumor lesions following pembrolizumab treatment with a PD‑L1 positive tumor. Treatment was discontinued for grade 3 mucositis after cycle 5. Pembrolizumab may provide some clinical beneft to some patients with vaginal or vulvar SCC and is overall safe to utilize in this population. Future studies are needed to evaluate the efcacy of pembrolizumab in these rare tumor types and to identify predictive biomarkers of response.

  • Influence of Age on Histologic Outcome of Cervical Intraepithelial Neoplasia
    www.nature.com/scientificreports OPEN Infuence of age on histologic outcome of cervical intraepithelial neoplasia during observational Received: 10 May 2017 Accepted: 6 April 2018 management: results from large Published: xx xx xxxx cohort, systematic review, meta- analysis Christine Bekos1, Richard Schwameis1, Georg Heinze2, Marina Gärner1, Christoph Grimm1, Elmar Joura1,4, Reinhard Horvat3, Stephan Polterauer1,4 & Mariella Polterauer1 Aim of this study was to investigate the histologic outcome of cervical intraepithelial neoplasia (CIN) during observational management. Consecutive women with histologically verifed CIN and observational management were included. Histologic fndings of initial and follow-up visits were collected and persistence, progression and regression rates at end of observational period were assessed. Uni- and multivariate analyses were performed. A systematic review of the literature and meta-analysis was performed. In 783 women CIN I, II, and III was diagnosed by colposcopically guided biopsy in 42.5%, 26.6% and 30.9%, respectively. Younger patients had higher rates of regression (p < 0.001) and complete remission (< 0.001) and lower rates of progression (p = 0.003). Among women aged < 25, 25 < 30, 30 < 35, 35 < 40 years, and > 40 years, regression rates were 44.7%, 33.7%, 30.9%, 27.3%, and 24.9%, respectively. Pooled analysis of published data showed similar results. Multivariable analysis showed that with each fve years of age, the odds for regression reduced by 21% (p < 0.001) independently of CIN grade (p < 0.001), and presence of HPV high-risk infection (p < 0.001). Patient’s age has a considerable infuence on the natural history of CIN – independent of CIN grade and HPV high- risk infection.

  • ASCO Answers: Ovarian, Fallopian Tube, and Peritoneal Cancer
    Ovarian, Fallopian Tube & Peritoneal Cancer What are ovarian, fallopian tube, and peritoneal cancers? The term “ovarian cancer” is often used to describe cancers that begin in the cells in the ovary, fallopian tube, and peritoneum. These types of cancer begin when healthy cells in these areas change and grow out of control, forming a mass called a tumor. Research suggests that high-grade serous cancer, which includes most ovarian cancer, usually starts in the fallopian tubes. Some peritoneal cancers also may begin in the fallopian tube. What are the functions of the ovaries, fallopian tubes, and peritoneum? The ovaries and fallopian tubes are part of a woman’s reproductive system. Typically, every woman has 2 ovaries, which contain eggs and are the primary source of estrogen and progesterone. These hormones play a role in breast growth, body shape, body hair, the menstrual cycle, and pregnancy. ONCOLOGY. CLINICAL AMERICAN SOCIETY OF 2004 © LLC. EXPLANATIONS, MORREALE/VISUAL ROBERT BY ILLUSTRATION There are 2 fallopian tubes, which are small ducts that link the ovaries to the uterus. During a woman’s monthly ovulation, an egg is usually released from 1 ovary and travels through the fallopian tube to the uterus. The peritoneum is a tissue that lines the abdomen and most of the organs in the abdomen. What do stage and grade mean? Staging is a way of describing a cancer’s location, if or where it has spread, and whether it is affecting other parts of the body. There are 4 stages for ovarian, fallopian tube, and peritoneal cancer: stages I through IV (1 through 4).
