Women also have the right to make these decisions free of discrimination, coercion and violence (12). It contains recommendations for counselling, care and other interventions that are based on the available scientific evidence and accumulated programmatic experience and supplemented by expert opinion where evidence is lacking or inconclusive. Sexual and reproductive health services are uniquely positioned to address each of these factors. Moreover, their choices may be limited by direct or indirect social, economic and cultural factors as well as medical factors. Information and counselling are critical components of all sexual and reproductive health services to support women in making these choices and carrying them out safely and voluntarily. Mediated disclosure to partners can be explored if the women concerned are in agreement. Couple counselling can reduce tensions between partners and enable both partners to make sexual and reproductive choices together as partners in a relationship. People retain the right to refuse testing: to opt out of a systematic providerinitiated offer of testing. This scaling up must be grounded in an approach that protects human rights and respects ethical principles so that testing is confidential, accompanied by counselling and only conducted with informed consent. Pretest counselling includes information on the clinical and prevention benefits of testing and the follow-up services that will be provided. Women who have experienced gender-based violence have low self-esteem or thoughts of suicide require additional counselling and support. Referral to health workers with specific training in these areas may be necessary. Sexual health, the state of physical, emotional, mental and social well-being in relation to sexuality, is an important and integral aspect of human development and maturation throughout the life cycle. Unfortunately, rather than women having satisfying and safe sexual experiences, their sexuality is often the cause of distress and characterized by unsafe or harmful sexual practices that lead to adverse health outcomes. Adult health status is closely linked to experiences during adolescence; adolescent sexuality sets the stage for sexual health in later life and is inseparable from adult sexuality. These factors include poverty, certain occupations, lack of power in sexual relationships, gender-based violence, harmful sexual practices and early marriage (21). Interventions to address the public health crisis stemming from unsafe sexual behaviour must be based on fundamental values and principles grounded in human rights; incorporate emotional, psychological and cultural factors; and address both the pleasure and safety aspects of sexuality and sexual health. Further, such interventions must be tailored to the specific circumstances within each country. Health care workers may require further training in human sexuality, to increase their capacity and confidence in addressing sexual health. S exual and reproductive health of women living with hiv/aidS Because of difficulties in addressing issues of sexuality with the opposite sex, it may be preferable that female health workers carry out sexual and reproductive health counselling for women. The impact of violence on mental health can be as serious and long-lasting as physical injuries and include posttraumatic stress disorder and depression (2). The risk of transmission increases with the degree of trauma and with vaginal lacerations and abrasions that occur when force is used. Further, violence against a woman can interfere with her ability to access treatment and care, maintain adherence to antiretroviral therapy or carry out her infant-feeding choice. Although discussions about sexual violence tend to focus on rape by strangers, acknowledging that coercive sex also happens within families and intimate relationships is crucial (4). Childhood sexual abuse, coerced sexual initiation and current partner violence are linked to increased risk-taking, including having multiple partners, non-primary partners (partnerships outside marriage, union or stable relationship) or engaging in transactional sex (2527). Studies in sub-Saharan Africa have found higher risks of disclosure-related violence compared with studies in the United States (29). To meet this challenge, health services need to acknowledge and address the gender-specific concerns and needs of women while seeking to transform gender roles and create more equitable relationships. Several strategies can be used to target the social attitudes, and gender and sexual norms, underlying violence against women. These prevention strategies can be effectively incorporated into various settings in the community, such as schools, youth groups and the workplace. However, despite these increases, many women who desire to postpone, space or limit pregnancies still have an unmet need for safe and effective contraception, especially in sub-Saharan Africa, where only 27% of women of reproductive age who are married or cohabiting use contraception compared with a world average of 61% (31). When motivation to regulate fertility is strong but effective contraception is inaccessible, many unintended pregnancies occur. Each woman is best placed to interpret the risks and benefits of available methods and she must make the final selection of a contraceptive method. It is achieved by using condoms alone or by using condoms together with another effective method of contraception, including emergency contraception. Such protection can also be realized through safe alternatives to penetrative sex. It is hoped that an alternative to condoms microbicides will provide an invaluable additional method of dual protection. In studies of contraceptive effectiveness with perfect use, male condoms are 98% effective and female condoms are 95% effective in preventing pregnancy (38). When not used consistently and correctly (typical use), effectiveness is lowered but still comparable to other contraceptive methods: 85% and 79%, respectively. Since adverse effects due to the addition of nonoxynol-9 to condoms cannot be excluded, such condoms should no longer be promoted. However, using nonoxynol9-lubricated condoms is better than using no condoms (41). Although it may be slightly less effective in preventing pregnancy than the male condom, the female condom does offer several advantages, including insertion prior to sexual intercourse, not having to be removed immediately after ejaculation and greater female control, although some degree of negotiation and male cooperation is required. To date, use of the female condom has been limited by cost, lack of widespread availability or familiarity and under-resourced promotion. Because condoms have a relatively higher failure rate with typical use, women who are very apprehensive about becoming pregnant are often offered other methods of contraception. When other contraceptive methods are used, consistent use of condoms may be less likely (46 48). Further, both providers and potential users may underemphasize the use of condoms in situations where preventing pregnancy is not a concern, such as in marriage or stable relationships, in cases of infertility, after sterilization or among older or postmenopausal women (49). However, if a woman is receiving antiretroviral therapy, potential drug interactions need to be considered (see sections 2. Evidence from several cross-sectional and prospective studies suggests that combined oral contraceptive users may be at a moderately elevated risk of acquiring Chlamydia infection (65). Evidence from two cross-sectional and two prospective studies suggests an increased risk of Chlamydia infection among depot medroxyprogesterone acetate users (65,66). For adequate protection from an unplanned pregnancy, women must be exclusively or nearly exclusively breastfeeding, have amenorrhoea and be less than six months postpartum (67). The safety concerns with nonoxynol-9 also apply to other spermicide products marketed for contraception. Particular attention is needed for young women or women with mental health problems, including depressive conditions. Health care workers should ensure that women are not pressured or coerced to undergo the procedure and that the decision is not made in a moment of crisis. The decision process must consider the national laws and existing norms for sterilization procedures. Emergency contraceptive pills can be used by women within five days of unprotected intercourse, although they are more effective if taken sooner (71). Based on the findings of a multicentre randomized trial (72), the preferred oral emergency contraceptive regimen consists of 1. This regimen is effective, has few side effects and is easier to use than other regimens. Although the interaction is not harmful to women, it is likely to reduce the effectiveness of hormonal contraception. Therefore, low-dose estrogen (35 µg) combined oral contraceptive is usually not recommended among women receiving rifampicin if other more appropriate methods are available and acceptable. Alternatively, a non-hormonal method of contraception may be used throughout rifampicin treatment and for at least one month thereafter.

Many important studies have been done regarding the most common tumors affecting the brain and spinal cord, and a variety of prognostic factors have been identified. This chapter, however, attempts to highlight what is known about prognostic factors in tumors of the central nervous system (Table 56. The histology of tumors that affect the brain and spinal cord is by far the most important variable affecting prognosis, and in many cases it determines the treatment modalities that are employed. This is a less powerful predictor than tumor histology or age, but most retrospective studies confirm that extent of removal is positively correlated with survival. Because of the differential importance of various areas of the brain, the location of a given tumor affecting the brain can have a major impact on the functional outcome, survival, and nature of therapy. This has been estimated traditionally using the Karnofsky Performance Scale, which is reproducible, is well known by most investigators, and is in common use for stratification of patients entering clinical trials for the treatment of brain tumors. The outcome and prognosis of patients correlate fairly well with functional neurologic status, and once again, any staging system should include a validated and reliable measure of this parameter. Tumors affecting the central nervous system rarely develop extraneural metastases, probably because of inherent biologic characteristics of these tumors, and also because the brain does not have a welldeveloped lymphatic drainage system. In addition, many patients with tumors of the central nervous system have a short life expectancy, which further limits the likelihood of metastatic spread. Primary lymphomas of the central nervous system may spread along the craniospinal axis and sometimes exhibit intraocular dissemination. Although metastatic spread is of importance in certain instances, its overall impact in staging is relatively minor. This helps to clarify some of the inconsistencies that existed in the past when a number of different grading systems, each slightly different from the others, were used. The most common histologies for brain and spinal cord tumors are given in Tables 56. Most retrospective outcome studies of brain tumor therapy show that the age of the patient at the time of diagnosis is one of the most powerful predictors of outcome. This fact holds true for the gliomas, which are the most common primary brain tumors, and for most other tumors that affect the adult population, including most metastatic tumors to the brain. There are, however, some childhood tumors that have a very poor prognosis, are inherently high grade, and rapidly progress to a fatal outcome. Some metastatic tumors, such as melanoma, occur in younger patients and also violate this general statement with regard to the specific effect of age on prognosis. In patients who are treated surgically for tumors of the central nervous system, the extent of resection is often directly correlated with the out- 594 American Joint Committee on Cancer 2010 In order to view this proof accurately, the Overprint Preview Option must be set to Always in Acrobat Professional or Adobe Reader.

Excellent observational insight and patterns of care data for surgically treated malignant gliomas [glioblastomas and malignant (grade 3) gliomas] are available from the Glioma Outcome Project, which evaluated 788 patients accrued from 1997 to 2000. One of the most promising is the codeletion of 1p 19q in anaplastic oligodendroglioma and its prognostic value.

Non-Hodgkin lymphomas occur in more than 63,000 new individuals each year and have been increasing in incidence over the past several decades. They include Hodgkin lymphoma (Hodgkin disease), non-Hodgkin lymphoma, multiple myeloma, and lymphoid leukemias. Thus, it is artificial to call them different diseases, when in fact they are just different presentations of the same disease. For this reason, we now refer to these diseases as lymphoid neoplasms rather than as lymphomas or leukemias, reserving the latter terms for the specific clinical presentation. In the current classification of lymphoid neoplasms, diseases that typically produce tumor masses are called lymphomas, those that typically have only circulating cells are called leukemias, and those that often have both solid and circulating phases are designated lymphoma/leukemia. Finally, plasma cell neoplasms, including multiple myeloma and plasmacytoma, have typically not been considered "lymphomas," but plasma cells are part of the B-cell lineage, and, thus, these tumors are B-cell neoplasms, which are now included in the classification of lymphoid neoplasms.

This scheme had the advantage of being simple, with only ten categories, and it did not require any special studies such as immunophenotyping or genetic studies. In addition, it provided simple clinical groupings for determining the approach to treatment (low, intermediate, and high clinical grades). Since its introduction, advances in understanding of the immune system and lymphoid neoplasms led to the recognition of many new categories of lymphoid neoplasms. The fact that several subtypes were in an incorrect category based on clinical behavior, and the development of better methods for diagnosis and classification as well as for treatment have caused the Working Formulation to become obsolete. Morphology remains the first and most basic approach and is sufficient for both diagnosis and classification in many typical cases of lymphoma. Immunophenotyping and particularly molecular genetic studies are not needed in all cases, but they are very important in some diseases, are useful in difficult cases, and improve interobserver reproducibility. Both lymphomas and lymphoid leukemias are included, because both solid and circulating phases are present in many lymphoid neoplasms, and drawing a distinction between them is arbitrary. Thus, B-cell chronic lymphocytic leukemia and B-cell small lymphocytic lymphoma are simply different manifestations of the same neoplasm, as are lymphoblastic lymphomas and acute lymphoblastic leukemias. In addition, Hodgkin lymphoma and plasma cell myeloma are now recognized as lymphoid neoplasms of B-lineage and, therefore, belong in a compilation of lymphoid neoplasms. The ability to study patterns of gene expression is providing new insights into these disorders. It is likely to change classification and might eventually supersede staging in the ability to predict outcome and the response to specific therapies.

The amount and duration of blood flow varies greatly but averages 2080 ml, lasting approximately 37 days. Between puberty and menopause, the ovarian cortex contains follicles and ova in various stages of development. The remaining follicles either fail to develop or degenerate without maturing completely. Benign Pathophysiology of the Ovaries Normally, the ovaries are somewhat tender and usually are palpable on pelvic examination in slender, relaxed women but are difficult or impossible to detect in others who are obese or unable to relax during the exam (Bickely & Szilagy, 2007). In perimenopausal and postmenopausal women, as ovarian function declines, the ovaries begin to atrophy, and they cannot be felt on bimanual examination (Bickley & Szilagyi; Cohen, 2006). Therefore, an ovary that can be palpated in a menopausal or postmenopausal woman should be considered an abnormality. Benign ovarian tumors: Adams-Hillard (2002) describe the following categories of benign ovarian tumors: (a) functional, (b) inflammatory, (c) neoplastic, (d) epithelial, and (e) other. Epithelial includes serous cystadenoma, fibroma, cystadenofibroma, Brenner tumor, and mixed tumor. Ovarian cysts: Ovarian cysts are growths arising from ovarian components and are usually benign (Adams-Hillard, 2002; Jackson & Lichtman, 1990; Snyder, 2005). They commonly arise from functional changes in the ovary such as from a Graafian follicle or from persistent corpus luteum. They are found frequently during childbearing years; however, masses found in women older than age 50 are more often malignant. Polycystic ovarian syndrome: Polycystic ovarian syndrome is a functional derangement of the hypothalamo-pituitary ovarian axis and is associated with anovulation. This is a complex syndrome with androgenic side effects, despite low serum total testosterone levels, as well as insulin resistance. Premature ovarian failure: Premature ovarian failure occurs as a result of the depletion of ovarian follicles from the ovary prior to the normal age of menopause, inducing premature menopause. Although the etiology is unclear, it is associated with chromosomal abnormalities such as Turner syndrome or autoimmune disease, or it may follow infections such as mumps. Women who experience abrupt menopause report greater symptom distress than women who experience menopause naturally (Ganz, Greendale, Petersen, Kahn, & Bower, 2003; Knobf, 2006). Long-term symptom management associated with abrupt menopause, regardless of the cause, is an important quality-of-life issue. Fallopian Tubes the two fallopian tubes, oviducts or uterine tubes, each measure about 812. The infundibulum has numerous irregular projections called fimbriae extending toward the ovary. The elongated segment of the fallopian tube proximal to the infundibulum is the ampulla. The ampulla leads to the isthmus, a short, narrow segment that opens into the uterine wall. The epithelium lining, the ampulla, has numerous sacklike grooves, and the exposed surface has hair-like appendages called cilia. The primary function of the fallopian tube is to propel the ovum via cilia and peristalsis from the space around the ovaries to the uterus. When the ovum is released from the ovarian follicle, it is swept into the fallopian tube by the wave-like action of the fimbriae. Here, the ovum may or may not encounter sperm, and it continues to travel through the fallopian tube to the uterus. If fertilized, the blastocyst implants itself in the endometrial layer of the uterine wall. If not fertilized, the ovum degenerates and leaves the uterus with the menstrual fluids. Disorders that affect the fallopian tubes can block the path of sperm and ovum and cause infertility. The middle layer, called the myometrium, is composed of a thick layer of smooth muscle, which is thickest at the fundus. The endometrium, the uterine lining, composed of a thick inner functional layer called the stratum functionalis, is the site of embryo implantation. Because the endometium is hormonally responsive, changes in its morphology fluctuate during the menstrual cycle (see Figure 2-3). When fertilization does not occur, the stratum functionalis of the endometrium sloughs off during menstruation. The deep layer, called the stratum basalis, provides tissue for regeneration of the stratum functionalis following menstruation. The functions of the uterus are to secure and protect the fertilized ovum, provide an optimal environment while it develops, and through the contractions of labor, facilitate birth. Uterine or endometrial events of the menstrual cycle are caused by ovarian hormones (see Figure 2-3). Benign Pathophysiology of the Uterus Uterine prolapse: Uterine prolapse is an abnormal position of the uterus in which the uterus protrudes downward. This may be caused by herniation of the uterus through the pelvic floor resulting in prolapse into the vagina or beyond the introitus (procidentia). This usually is caused by obstetric trauma and overstretching of musculofascial supports. Endometriosis: Endometriosis is the abnormal proliferation of uterine endometrial tissue outside the uterus, also occurring outside of the pelvic cavity. Risk increases among siblings of women who have endometriosis and among women with shorter menstrual cycles and longer duration of flow. It is more common in white women than black women and in those with sedentary lifestyles and who are obese. Endometriosis may be caused by embryonic tissue remnants that differentiate as a result of hormonal stimulation and spread via lymphatic or venous channels. It may be caused by retrograde menstruation through fallopian tubes into the peritoneal cavity and may also be transferred via surgical instruments. Menstruation resulting in accumulated blood and inflammation and subsequent adhesions also may be associated with endometriosis. Elevated estrogen levels increase endometriosis, whereas lower estrogen levels and increased progestins cause regression of endometriosis. Therefore, hormonal contraceptive and androgen use will decrease symptoms of endometriosis. The uterus weighs approximately 3060 grams and is surrounded by and held loosely in place by ligaments, peritoneal tissue folds, and the pressure of adjacent organs (especially the urinary bladder, sigmoid colon, and rectum). In most women, the uterus is anteverted (tipped forward) resting on the urinary bladder. It may also be retroverted (tipped backward), or less often, midposition (upright). The uterus is composed of two parts: the body or corpus, which is the superior, thick-walled portion, and the cervix, the lower portion that extends into the vagina. These two parts are joined together by the isthmus, which is the narrowed part of the corpus. The fundus is the convex upper portion of the uterus where the fallopian tubes are suspended. The diameter of the uterine cavity is widest at the fundus and narrowest at the isthmus. Cervix the cervix, or opening of the uterus, is the narrow, lower portion that extends from the isthmus to the vagina. The external os of the cervix, a slit-like depression, opens into the vagina dividing it into the anterior, posterior, and lateral fornices.

A diagnosis of sex cord stromal tumor must be considered in someone who presents with signs of estrogen excess antiviral medication side effects order 250 mg famvir fast delivery, including abnormal uterine bleeding, secondary amenorrhea, or endometrial hyperplasia/ carcinoma (Dorigo & Berek, 2009). Almost all prepubescent girls with these tumors present at stage I and are unilateral. The signs and symptoms include breast enlargement, development of pubic and axillary hair, irregular uterine bleeding, and other secondary sex characteristics. Infrequently, patients present with a virilization syndrome because the tumor is androgen-secreting (Colombo et al. The size of the tumor can vary from a microscopic lesion not detectable at a pelvic exam to a very large mass; the average is around 12 centimeters (Colombo et al. Juvenile tumors developing in women after puberty present similar to the adult type with abdominal pain or swelling. Severe pain at diagnosis is usually from adnexal torsion, hemorrhage into the tumor, or rupture of a cystic component. Granulosa cell tumors tend to be hemorrhagic and occasionally rupture (Fox, Agrawal, & Langley, 1975; Schumer & Cannistra, 2003; Stenwig et al. Inhibin is a heterodimeric polypeptide hormone that is produced by the ovaries in response to follicle-stimulating hormone and luteinizing hormone (Dorigo & Berek, 2009). Estradiol was used as a marker because it is secreted by granulosa cell tumors, but it is not a sensitive enough tumor marker for the disease. These tumors are large and unilateral, are usually multicystic, and have a yellow coloration from accumulation of lipids. An ultrasound is recommended preoperatively along with an endometrial biopsy because of the correlation with endometrial hyperplasia and cancer (Schumer & Cannistra, 2007). Histologic diagnosis is made by immunohistochemical staining for markers of granulosa cell tumors, including (Hildebrandt, Rouse, & Longacre, 1997; Matias-Guiu et al. The prognostic factor that is the most significant for granulosa cell tumor is the surgical stage. Other prognostic factors remain more controversial, including (Schumer & Cannistra, 2003) Tumor size (larger than 1015 cm associated with inferior survival) Mitotic index (greater than or equal to 410 mitoses per 10 high-power fields worse prognosis in some series) Tumor rupture (some think it is worse, but equivocal) Age (younger than 40 worse prognosis). Staging Surgery is the cornerstone of management of this disease for definitive diagnosis, staging, and removing as much tumor as possible-the same as all ovarian cancers. Treatment the treatment plan depends on the age of the patient and the extent of the disease. Surgery alone is sufficient treatment for most cases of granulosa cell tumors, with chemotherapy or radiation therapy reserved for those patients with recurrent or metastatic disease (Colombo et al. Surgery A staging laparotomy procedure with careful inspection of the contralateral ovary and tube, as well as the pelvic and para-aortic lymph nodes, is needed (Dorigo & Berek 2009). Retrospective studies show equal cure rates for unilateral versus bilateral salpingo-oophorectomy (Gershenson, 1994; Zhang et al. The long-term disease-free survival rates for women with stage I disease is approximately 90% (Dorigo & Berek). Positive outcomes are slightly less for women with higher stage disease or stage I disease with tumor larger than10 cm, if the tumor ruptures, or if the tumor has a high mitotic index (Dorigo & Berek). Chemotherapy the low number of women with sex cord stromal tumors makes randomized clinical trials difficult to conduct. No evidence exists that proves adjuvant chemotherapy will prevent recurrences in stage I disease because the disease has an overall good prognosis and the disease is indolent in nature. Postoperative chemotherapy must be part of the treatment plan for those women with advanced disease. Most recently, platinum and paclitaxel therapy had favorable results and a better toxicity profile (Brown et al. Radiation No evidence supports the use of postoperative radiation for granulosa cell tumors. Palliative radiation may delay growth of isolated recurrent disease in the pelvis (Savage et al. Granulosa cell tumors are labeled as radioresponsive, and radiation can induce clinical responses and occasional long-term remissions (Wolf et al. Overall, some patients may benefit from radiotherapy if their disease does not seem amenable to surgery; every case should be considered individually (Colombo et al). If pelvic or intra-abdominal disease is present, consideration may be given to surgery followed by postoperative radiation. Median time to recurrence is four to six years after the initial diagnosis, but late recurrences have been reported as many as 40 years after diagnosis (Berek & Hacker, 2005; Wolf et al. Surveillance should include a pelvic examination and serum inhibin levels every three months for two years, then every four to six months for three to five years, and then annually (Dorigo & Berek, 2009; Schumer & Cannistra, 2003). Platinum-based chemotherapy is a reasonable choice for more widespread disease or disease that is suboptimally debulked. Use of hormonal agents or antiestrogens has been suggested, but no data support the effectiveness of this treatment approach (Schumer & Cannistra). The more infrequently occurring sex-cord tumor characteristics and general treatment approaches are summarized in Table 8-4. Rare Nonepithelial Ovarian Tumors Small Cell Carcinoma Ovarian small cell carcinoma usually presents with bilateral disease at an average age of 24 years (Young, Oliva, & Scully, 1994). More than half of women have disease spread beyond the pelvis at diagnosis, and similar to small cell carcinoma of the lung, it is very aggressive and often fatal. Treatment includes platinum-based chemotherapy and/ or radiation (Berek & Hacker, 2005). Lipoid Cell Tumors Lipoid cell tumors are theorized to originate in adrenal cortical rests near the ovary (Berek & Hacker 2005). The tumor most often presents unilaterally, and at presentation the patient may exhibit virilization, obesity, hypertension, and/or glucose intolerance (Berek & Hacker). The tumor is mostly benign or low grade, and surgical removal of the primary lesion is the primary treatment (Berek & Hacker). Sarcomas Malignant mixed mesodermal sarcoma is a very rare ovarian tumor that occurs in postmenopausal women. Found in postmenopausal women Present with abnormal bleeding Benign solid tumors Unilateral Postmenopausal women Not hormonally active May have ascites Occur in women under age of 40 Large, confined to one ovary May present with hormonal changes or abdominal pain or increasing abdominal girth. Pure Leydig tumors-androgen secreting and cause virilization, oligomenorrhea, amenorrhea, breast atrophy, hirsutism, deepening voice, male pattern baldness, acne, clitoral enlargement. Surgery followed by platinum-based chemotherapy is the recommended treatment (Barakat et al. Germ cell tumors of the ovary: Is there a role for aggressive cytoreductive surgery for nondysgerminomatous tumors? Most have a good prognosis, are characterized by slow growth with local spread, and are treated with surgery. Because these tumors present in such a wide age range of women (from prepuberty to postmenopausal), the care of every patient must be individualized.
