The World Health Organization bined into a single grade – for example, poorly differentiated Classification of Tumours published in numerous anatomic to undifferentiated (G3–4).

Thus, if a survival rate is to describe which the available data represent the population, and the qual the outcomes for an entire group accurately, there must be ity and completeness of registry data. In this chapter the most some means to deal with the fact that different people in common survival analysis methodology is illustrated, basic the group are observed for different lengths of time and terminology is defined, and the essential elements of data col that for others, their vital status is not known at the time of lection and reporting are described. A survival curve is a summary display for each patient and is preferable when data are available in of the pattern of survival rates over time. The greater the proportion clearly indicated in the report to avoid any confusion asso surviving, the lower the risk for this category of patients. Rates com Survival analysis, however, is somewhat more complicated puted by different methods are not directly comparable, and than it first might appear. If one were to measure the length of when the survival experiences of different patient groups are time between diagnosis and death or record the vital status when compared, the different rates must be computed by the same last observed for every patient in a selected patient group, one method. The In most real situations, not all members of the group are cases selected are a 1% random sample of the total num observed for the same amount of time. Thus, at last contact and will have been followed for less time than for the earliest patients, there can be as many as 16 years of those diagnosed earlier. Even though it was not possible to follow-up, but for those diagnosed at the end of the study follow these persons as long as the others, their survival might period, there can be as little as 1 year of follow-up. Although we do are used both because they are realistic in terms of the actual not know the complete survival time for these individuals, we survival rates they yield and because they encompass a num do know a minimum survival time (time from diagnosis to ber of cases that might be seen in a single large tumor registry Cancer Survival Analysis 15 In order to view this proof accurately, the Overprint Preview Option must be set to Always in Acrobat Professional or Adobe Reader. Survival of 2,347 lung cancer patients from during the interval and the number estimated to have been at the Surveillance, Epidemiology, and End Results Program risk at the start of the interval. An important assumption of all actuarial survival the lung cancer data show a much different survival pat methods is that censored cases do not differ from the entire tern (Figure 2. For lung cancer patients the likely not to have died yet, tended to be detected with earlier median survival time is 10. Thus, it is important, when patients are included in a life table analysis, that one be reasonably confident that differences in the amount of infor mation available about survival are not related to differences that might affect survival. For example, it would be misleading to compare the 2 overall survival depicted in Figure 2.

This is particularly true when the calculated using the cause-adjusted survival rate, defined as series is small or when the patients are largely drawn from a the proportion of the initial patient group that escaped death particular socioeconomic segment of the population. This approach, however, is limited to factors into which patients may be the treatment of deaths from other causes as censored is con broadly grouped. This approach does not lend itself to troversial, since statistical methods used in survival analysis studying the effects of measures that vary on an interval settings assume that censoring is independent of outcome. Estimation of the adjusted curves that result provides so many comparisons that the rate as described previously does not appropriately distin effects of the factors defy interpretation.

Primary hypothyroidism may result from thyrodiectomy (surgical removal) or ablation of the gland with radiation 6mp medications purchase genuine persantine. Certain goitrogenic agents treatment molluscum contagiosum order persantine with american express, such as lithium carbonate (used in the treatment of manic-depressive states) and the antithyroid drugs propylthiouracil and methimazole in continuous dosage symptoms 7 days after implantation buy persantine online, can block hormone synthesis and produce hypothyroidism 173 Pathophysiology with goiter treatment viral meningitis cheap persantine 100mg on-line. Large amounts of iodine can also block thyroid hormone production and cause goiter, particularly in persons with autoimmune thyroid disease. Probably the most common cause of hypothyroidism is Hashimato’s thyroiditis, an autoimmune disorder in which the thyroid gland may be totally destroyed by an immunologic process. Although the disorder generally causes hypothyroidism, a hyperthyroid state may develop mid course in the disease. The transient hyperthyroid state is due to leakage of performed thyroid hormone from damaged cells of the gland. The hypometabolic state associated with myxedema is characterized by a gradual onset of weakness and fatigue, a tendency to gain weight despite a loss in appetite, and cold intolerance. As the condition progresses, the skin becomes dry and rough and acquires a pale yellowish cast, which is due primarily to carotene deposition, and the hair becomes coarse and brittle. Gastrointestinal motility is decreased, giving rise to constipation, flatulence, and abdominal distention. Nervous system involvement is manifested in mental dullness, lethargy, and impaired memory. As a result of fluid accumulation, the face takes on a characteristic puffy look, especially around the eyes. Myxedematous fluid can collect in the interstitial spaces of almost any organ system. Mucopolysaccharide deposits in the heart cause generalized cardiac dilatation, bradycardia, and other signs of altered cardiac function. It is characterized by coma, hypothermia, cardiovascular collapse, hypoventilation, and severe metabolic disorders that include hyponatremia, hypoglyoemia, and lactic acidosis. The fact that it occurs more frequently in winter months suggests that cold exposure may be a precipitating factor. The severely hypothyroid person is unable to metabolize sedatives, analgesics, and anesthetic drugs, and these agents may precipitate coma. It is commonly associated with hyperplasia of the thyroid gland, 176 Pathophysiology multinodular goiter, and adenoma of the thyroid. Occasionally it develops as the result of the ingestion an overdose of thyroid hormone. When the condition is accompanied by exophthalmos and goiter, it is called graves’ disease. Thyroid crisis, or storm, is an acutely exaggerated manifestation of the hyperthyroid state. Many of the manifestations of hyperthyroidism are related to the increase in oxygen consumption and increased utilization of metabolic fuels associated with the hyper metabolic state as well as the increase in sympathetic nervous system activity that occurs. The fact that many of the signs and symptoms of hyperthyroidism resemble those of excessive sympathetic activity suggests that the thyroid hormone may heighten the sensitivity of the body to the cadecholamines or that thyroid hormone itself may act as a pseudo catecholamine. With the hypermetabolic state, there are frequent complaints of nervousness, irritability, and fatigability. Other manifestations include tachycardia, palpitations, shortness of breath, excessive sweating, and heat intolerance. Even in persons without exophthalmos there is an abnormal retraction of the eyelids and infrequent blinking and patients appear to be staring. The hair and skin are usually thin and have a silky 177 Pathophysiology appearance. Hyperthyroidism can be treated by surgical, radioactive iodine or the use of drugs. Graves’ disease Graves’ disease is a state of hyperthyroidism, goiter, and exophthalmos. The cause of graves’ disease and the development of the exophthalmos, which results from edema and cellular infiltration of the orbital structures and muscle, is poorly understood. The exophthalmos is thought to result from an exophthalmos-producing factor whose action is enhanced by anti bodies. The ophthalmopathy of Graves’ disease can cause severe eye problems, including paralysis of the extraocular muscles, involvement of the optic nerve with some visual loss, and corneal ulceration since the lid do not close over the protruding eyeball. Thyroid storm Thyroid storm (crisis) is an extreme and life threatening form of thyrotoxicosis. It is often precipitated by stress, such as infection, by diabetic ketoacidosis, by physical or emotional trauma, or by manipulation of a hyperactive thyroid gland during thyroidectomy. Thyroid storm is manifested by a very high 178 Pathophysiology fever, extreme cardiovascular effects and severe central nervous system effects. Mineralocorticoids may be produced in excessive or insufficient amount, depending on the precise enzyme deficiency. Males are seldom diagnosed at birth, unless they have enlarged genitalia or lose salt and manifest adrenal crisis; in female infants, an increase in androgens is responsible for creating the virilization syndrome of ambiguous genitalia. Primary adrenal insufficiency, or Addison’s 179 Pathophysiology disease, is due to the destruction of the adrenal gland. Primary adrenal insufficiency (Addison’s disease) Addison’s disease is a relatively rare disorder in which all the layers of the adrenal cortex are destroyed. Most often the underlying problem is ideopathic adrenal atrophy, which probably has an auto immune basis. Addison’s disease is a chronic metabolic disorder that requires lifetime hormone replacement therapy. The adrenal cortex has a large reserve capacity, and the manifestations of adrenal insufficiency do not usually became apparent until about 90% of the gland has been destroyed. Mineralocorticoid deficiency: minerals corticoid deficiency caused increased urinary losses of sodium, chloride, and water along with decreased excretion of potassium. The result is hyponatremia, loss of extra cellular fluid, decreased cardiac out put, and hyper calemia. If loss of sodium and water is extreme cardiovascular collapse and shock will ensue. Gluco corticoid deficiency: Because of a lack of glucocorticoids, the patient has poor tolerance to stress. This deficiency causes hypoglycemia, lethargy, weakness, fever, and gastrointestinal symptoms such as anorexia, nausea, vomiting and weight loss. Secondary adrenal insufficiency Secondary adrenal insufficiency can occur as a result of hypopituitarism or because the pituitary gland has been surgically removed. However, a far more common cause than either of these is the rapid withdrawal of qluco-corticoids that have been administered therapeutically. Acute adrenal crisis Acute adrenal crisis is a life –threatening situation of addison’s disease is the underlying problem, exposure to even a minor illness or stress can preciptate nausea, vomiting, muscular weakness, hypotension, dehydration, and vascular collapse. The onset of adrenal crisis may be sudden, or it may progress over a period of several days. The symptoms may also occur suddenly in children with salt-losing forms of the adrenogenital syndrome. Massive bilateral adrenal hemorrhage cause an acute fulminating form of adrenal insufficiency. Hemorrhage can be caused by meningococcal septicemia (called water house-friderichsen syndrome), adrenal trauma, anticoagulant therapy, adrenal vein thrombosis, or adrenal metastases. Gluco corticoid hormone excess (cushing’s syndrome) Cushing’ syndrome is characterized by a chronic elevation in glucocorticoid (and adrenal androgen) hormones. The other forms of excess glucocorticoid levels are refereed to as Cushing’s Syndrome. The major manifestations of Cushing’s Syndrome represent an exaggeration of the normal effects of cortisol. Altered fat metabolism causes a peculiar deposition of fat characterized by a protruding abdomen; subclavicular fat pads or “ buffalo hamp” on the back; and a round, plethoric “moon face. In advanced cases, the skin over the forearms and legs becomes thin, having the appearance of parchment. Purple striae (stretch mark), from 183 Pathophysiology stretching of the catabolically weakened skin and subcutaneous tissues, are distributed on the abdomen and hips. Osteoporosis results from destruction of bone proteins and alterations in calcium metabolism. Derangements in glucose metabolism are found in some 90% of patients, with clinically overt diabetes mellitus occurring in about 20%.

The relationship of cervical cancer and sexual behavior was suspected for more than 100 years and was established by epidemiologic studies in the 1960s. About 40 types infect the mucosal epithelium; genetic sequence of the outer 11 these are categorized according to their epidemiologic capsid protein L1 association with cervical cancer. Infection with low-risk, fi About 40 types infect the or nononcogenic types, such as types 6 and 11, can cause mucosal epithelium benign or low-grade cervical cell abnormalities, genital warts and laryngeal papillomas. High-risk types and Disease Association (currently including types 16 and 18, among others) can mucosal/ nonmucosal/cutaneous cause low-grade cervical cell abnormalities, high-grade genital(~40 (~80 types) types) cervical cell abnormalities that are precursors to cancer, high-risk types 16, 18 (and others) low-risk types skin and anogenital cancers. Type 16 is the cause of approxi and feet) mately 50% of cervical cancers worldwide, and types 16 • low grade cervical •low grade cervical abnormalities abnormalities and 18 together account for about 70% of cervical cancers. Although the incidence of infection is high, most infections resolve spontaneously. A small proportion of infected persons become persistently infected; persistent infection is the most important risk factor for the development of cervical cancer. However, laboratory reagents used for these assays are not standard ized and there are no standards for setting a threshold for a positive result. Medical management depends on treatment of the specific clinical manifestation of the infection (such as genital warts or abnormal cervical cell cytology). Transmission occurs most frequently with fi Temporal pattern sexual intercourse but can occur following nonpenetrative None sexual activity. In a prospective study of college women, the cumulative incidence of infection was 40% by 24 months after first sexual intercourse. Communicability can be presumed to be high because of the large number of new infections estimated to occur each year. Results of epidemiologic studies are less consistent for other risk factors, including young age at sexual initiation, number of pregnancies, genetic factors, smoking, and lack of circumci sion of male partner. Population-based estimates, primarily from clinics treating persons with sexually transmitted infections, indicate that about 1% of the sexually active adolescent and adult population in the United States have clinically apparent genital warts. This exceeds the economic burden of any other sexually transmitted infection except human immunodefi ciency virus. Cervical Cancer Screening Most cases and deaths from cervical cancer can be Cervical Cancer Screening prevented through detection of precancerous changes within the cervix by cervical cytology using the Pap test. Currently fi Revised in 2012 available Pap test screening can be done by a conventional fi Screening should begin at age Pap or a liquid-based cytology. Since 2012, all organizations have recommended that screening should begin at age 21 years. While there are slight differences in other aspects of the recommendations, all groups recommend screening in women aged 21 to 65 years with cytology (Pap test) every 3 years. It is available in 2 types fi a 9-valent vaccine licensed in of prefilled syringes. However, there is no known serologic contains types 16 and 18 correlate of immunity and no known minimal titer (high risk) determined to be protective.

Further follow-up of vaccinated cohorts may allow determination of serologic correlates of immunity in the future. Study populations will continue to be type did not diminish efficacy followed for any evidence of waning immunity. Males aged 22 through 26 years without age these risk factors may be vaccinated as well. The second and third doses should be administered 1 to 2 and 6 months after the first dose. The third dose need not be repeated as long as it was administered at least 16 weeks after the first dose and at least 12 weeks after the second dose. If the series is interrupted after the first 6 months dose, the second dose should be given as soon as possible, fi An accelerated schedule using and the second and third doses should be separated by an minimum intervals is not interval of at least 12 weeks. If only the third dose is delayed, recommended it should be administered as soon as possible. Administering all indicated vaccines at a single visit increases the likelihood that adolescents and young adults will receive each of the vaccines on schedule. Each vaccine should be administered using a separate syringe at a different anatomic site. However, the immune response and vaccine efficacy might be less than that in persons who are immunocompetent. A moderate or severe acute illness a vaccine component or is a precaution to vaccination, and vaccination should be following a prior dose deferred until symptoms of the acute illness improve. The vaccine has not been causally associated with adverse pregnancy outcomes or with adverse effects on the developing fetus, but data on vaccination during pregnancy are limited.
