The metastases occur in the pelvic nodes and also in the aortic nodes.The upper aortic infra-renal lymph nodes are of special concern because of the direct drainage from the left ovarian vein to the left renal vein and the right ovarian vein to infra-renal vena cava. Because of the high incidence of lymphatic metastasis, bilateral pelvic and aortic lymphadenectomy is indicated in all ovarian cancers. In early stage ovarian cancer, systematic lymph node dissection is required in order to perform accurate clinical staging and to select an adequate adjuvant chemotherapy. For advanced cancer with minimal tumour residuals of up to 10mm, systematic lymphadenectomy will produce a significant benefit in progression- free survival, and may improve the 5- year overall survival. Laparotomy remained for years the prevailing method for the management of ovarian cancer, including pelvic and para-aortic lymphadenectomy. Although, minimally-invasive surgery has been dramatically increased in the recent years and has been widely adopted in gynecological procedures, providing a few of benefits. The aim of this study is to present and understand all the available minimally-invasive techiques that have been reported for pelvic and para-aortic lymphadenectomy in ovarian cancer and successfully end up to the most feasible, minimal invasive, efficient and most economic. The parameters which will be analyzed is the operative time, the estimated intraoperative blood loss, the postoperative pain, the length of hospital stay, the number of lymph nodes yielded and the complication rates. 6 PART I 1. OVARIAN CANCER Ovarian cancer begins in the ovaries. Ovaries are reproductive glands found only in females. The ovaries produce eggs (ova) for reproduction. The eggs travel through the fallopian tubes into the uterus where the fertilized egg implants 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 in the pelvis. Picture 1. (http://www.medicinenet.com/ovarian_cancer/article.htm) The ovaries are made up of 3 main 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. Most ovarian tumors are epithelial cell tumors. Germ cell tumors start from the cells that produce the eggs (ova). Stromal tumors start from structural tissue cells that hold the ovary together and produce the female hormones estrogen and progesterone. Most of these tumors are benign (non-cancerous) and never spread beyond the ovary. Benign tumors can be treated by removing either the ovary or the part of the ovary that contains the tumor. Malignant (cancerous) or low malignant potential ovarian tumors can spread (metastasize) to other parts of the body and can be fatal. 7 2. INCIDENCE AND EPIDEMIOLOGY The estimated number of new ovarian cancer cases in Europe in 2012 was 65 538 with 42 704 deaths [1]. There is variation in the incidence rate across the continent with a higher incidence in northern European countries. In the USA, there were 20 400 newly diagnosed cases and 14 400 deaths in 2009 [2]. Ovarian cancer is the fifth most common type of cancer in women and the fourth most common cause of cancer death in women. The estimated lifetime risk for a woman developing ovarian cancer is about 1 in 54. Ovarian

  • ABSTRACTS EXPERIMENTAL STUDIES; ANIMAL TUMORS Similarity Between Fasciations in Plants and Tumors in Animals and Their Genetic Basis, D
    ABSTRACTS EXPERIMENTAL STUDIES; ANIMAL TUMORS Similarity between Fasciations in Plants and Tumors in Animals and Their Genetic Basis, D. F. JONES. Science 81: 75-76, 1935. The author compares tumors in animals with fasciations in plants-irregular de- velopment of the growing points of the main stem or branches. Both are forms of un- regulated growth, though fasciations do not exhibit the malignant features which characterize many animal neoplasms. In some cases fasciated plants are able to reproduce, and all their descendants show the same abnormality. In many others, fasciations occur only in one part of a plant and so sporadically that they seem not to have any basis in inheritance; yet they appear more frequently in some germinal lines than in others. Fasciations can develop only in growing points. In animals, similar growths may occur wherever there are dividing cells, as particularly in glands and in tissues regenerat- ing after an injury. It is possible that unregulated proliferation may be the result of chromosomal unbalance, and significant that tar, aniline dyes, x-rays, and radium, all of which may initiate unregulated growth, will also cauae chromosomal aberrations. If these act indirectly through the manifestation of hemizygous recessive genes or the total loss of genes necessary for normal growth, or directly as a result of chromosome unbalance in particulrtr regions, it is easy to understand why unregulated growths occur sporadically but with higher frequencies in some families than in others.

  • The Development of the Lymphatics in the Small Intestine of the Pig
    THE DEVELOPMENT OF THE LYMPHATICS IN THE SMALL INTESTINE OF THE PIG. BY GEORGE HEUER. From the dnatoinical Laboratory of the Johns Hopkins Uiaiversity. WITH 17 FIGUEES. The recent American work on the lymphatic system has given us a new conception of the morphology of the system as a whole. The primitive lymphatic system consists of a number of sacs which are derived from the veins and which become united into a system for the most part by the thoracic duct. A further essential of this primitive system is that all of the sacs give up their connection with the veins, and only the two in the neck rejoin the vein to form the permanent opening. Thns far three sets of paired sacs and two unpaired ones have been described: the jugular sacs, the subclavian which in human embryos are an extension of the jugular, and the sciatic are the paired, the retroperitoneal sac and the cisterna chyli are the unpaired. It is the retroperitoneal sac which especially concerns us in this paper, for it is the source of the lym- phatics of the intestine. This primitive system is complete and can be injected in pig embryos 2.7 cm. long. The idea that the sacs form a primitive lymphatic system is not the most fundamental conception of this new theory, but rather that these sacs arise from the veins and in turn give rise to the lym- phatic vessels, so that we may say that the lymphatic system as a whole is derived from the blood vascular system, that lymphatics are modified veins, and that the growth of lymphatics is alwayvs from center to periphery.
