Mammalian -fetoprotein is classified as a member of the albuminoid gene superfamily. Thematernalserum-fetoproteinis a useful marker for women harboring a malignant germ cell tumor containing an endodermal sinus tumor or embryonal component. Initiallyproducedbytheyolksacandlaterbythe fetal liver and gastrointestinal tract, -fetoprotein is also the predominant protein synthesized during fetal development. Pregnant women with marked elevations of serum -fetoprotein should have a germ cell cancer or liver tumor included in the differential diagnosis. AsBoulayandPodczaskipointoutintheirexcellentreview on ovarian cancer complicating pregnancy, the use of fetoproteinlevelstomonitorwomenwithahistoryofendodermal sinus tumor who subsequently become pregnant poses a distinct clinical dilemma. One way to distinguish between ovarian (ie, yolk sac) -fetoprotein and fetal (ie, liver) -fetoprotein is to divide the heterogeneous human fetoprotein into various subfractions stratified by differential reactivitywithlectins,suchasconcanavalinA. Assaychromatography with concanavalin sepharose A will separate the -fetoprotein into either the yolk sac or liver variant because theyolksacformof-fetoproteincontainsthecarbonalsugar andisthetypeproducedbytheendodermalsinustumor. Because the enzyme is ubiquitous, the heterogeneity afforded its multiple molecular forms permits electrophoretic separation into five isoenzymes. Isoenzyme fractions 1 and 2 are specifically elevated in women with dysgerminomas. Inhibin is a glycoprotein hormone produced by normal ovarian granulosa cells and testicular Sertoli cells. Patientswithgranulosacelltumorshaveelevatedserumlevels of inhibin, and this finding has been used to detect recurrent tumor. In pregnancy, serum levels of inhibin do not rise significantlyunlessthepatienthaspreeclampsiaorgestational hypertension. IntheUnitedStates,thereare30,000newcasesofleukemiaand 20,000 deaths are attributable to the disease each year. Themedian survival time is approximately 2 years, with 25% of patients becominglong-term,disease-freesurvivors. Indeed, the majority of adult patients who achieve remission subsequentlyexperiencerecurrence. Therefore, if the patient is remote fromdelivery,appropriatetreatmentwillplacethefetusatrisk ofexposuretochemotherapeuticagents,radiationtherapy,or both. The outcome of pregnancy-associated acute leukemia is only worsewhencomparedwithnonpregnantcaseswhentherapyis delayed. Seventy-five percent of pregnant women enter into complete remissionaftertherapyforacuteleukemia,owingtotheirfavorableage. Whenthediagnosisismadelater in pregnancy, it should be recognized that there are obvious advantages of delivery before the onset of chemotherapy, and thisshouldbeencouraged,ifpossible. The fibrinogen level in patients with acute leukemia in pregnancy maybereducedfromthelevelanticipatedatthatstageofgestation. FrenkelandMeyersstatedthatpregnancyexertsnospecific effectonthecourseofacuteleukemiaexceptthatearlygestation poses an obstacle to vigorous treatment of leukemia. Lilleymanand colleagues and Bitran and Roth have written comprehensive reportsonthissubject. In 1984, Catanzarite and Ferguson published a reviewofmanagementandoutcomeofacuteleukemiainpregnancyfortheyears1972to1982. Theinvestigatorscollected14 pregnancies reported in patients cured of acute lymphocytic leukemia,ofwhichtherewasoneearlyspontaneous abortion and13terminfants. In 40 pregnancies in which acute leukemia was treated, there were five abortions, three perinatal demises, one infant"liveborn in grave condition," and 31 surviving infants. Median maternal survival was at least 6 months and possibly longer than12monthsfromdelivery. Advancesinthefieldsofhematology and oncology, maternal and fetal medicine, and neonatology have resulted in marked improvements in both perinatal survivalstatisticsandmedianmaternalsurvivaltime. In women who refuse pregnancy termination or in whom delivery is not expected imminently, induction of remission shouldbeattempted. Whencombinationtherapyisusedduring the first trimester (and for acute leukemia in pregnancy, this is not a contraindication), the stillbirth rate is 25%-this decreasesto13%inthesecondandthirdtrimesters. A combination of cytarabine, doxorubicin, and etoposide has been used with good results for both mother and fetus, and when possible, we recommend this regimen. Delivery should be timed to precede the next course of chemotherapy; however, themajorityofpatientsshouldbecounseledtoexpectpreterm delivery, either spontaneous or induced. Althoughnogrowthordevelopmentalabnormalitieshavebeen demonstrated, the follow-up of children exposed to in utero chemotherapyforthemanagementofacuteleukemiahasbeen limited.

Inanefforttodeterminewhatcontribution (if any) breastfeeding has on the subsequent development of breastcancer,theCollaborativeGrouponHormonalFactorsin BreastCancerexaminedtheindividualdatafrom47epidemiologic studies in 30 countries that included information on breastfeeding patterns. In total, 50,302 women with invasive breastcancerwerecomparedwith96,973controlparticipants. The investigators noted that women with breast cancer had fewerbirthsthandidcontrolparticipants(2. Thus,thelongerwomen breastfed, the more they were protected against breast cancer. Hormonal Considerations: Pregnancy Coincident With Breast Cancer Although there is no clear evidence that pregnancy adversely affects the course of this disease, the suspicion persists. However, thelowincidenceofstageIlesionsinpregnancystronglysuggests an acceleration of the disease process in the preclinical period. Manycellkineticstudiesofbreastcancersuggestthat lesions are harbored within the breast for 5 to 8 years before becomingclinicalentities. Becausetheperiodofgestationisno longer than 9 months, it is difficult to believe that the sole explanation for the high incidence of advanced disease in pregnancy is related to late diagnosis caused by the engorged breast. Urinaryexcretion of all three major fractions-estrone, estradiol, and estriol-rises progressively after the eighth week of gestation, althoughthereisadisproportionateriseinestriolproduction by the placenta. The ability of estrogens to promote growth of breast cancer in animals and humans has been amply illustrated. Whether the stimulatory effect of increasedestrogenproductionhasanadverseeffectonprognosis or whether the disproportionate rise of estriol, a relatively weakestrogenandapossibleantagonistofestroneandestradiol, conferssomemeasureofprotectionisunknown. Meanproduction of 17-hydroxycorticosteroids increases from 12mg/24 hours to approximately 18mg/24 hours in late pregnancy. Because glucocorticoids can reduce cellular immunity and perhaps promotetheimplantationandgrowthofmalignantneoplasms, thisincreasedproductionhasgraveclinicalimplications. Similarly, elevated levels of prolactin produced by the hypophysis and of human placental lactogen by the placenta late in pregnancy and during milk production might affect breast cancer adversely. Prolactin promotes the growth of dimethylanthracene-induced mammary tumors in mice. The levels of prolactin in patients with breast cancer are not appreciably different from those in control subjects, and prolactin suppression with ergot compounds or withl-dopahasnotprovedtobeoftherapeuticvalue. However, the observation that women with bone pain from metastatic breastcancersometimesobtainrelieffromprolactinsuppressionimplicatesprolactinasapossiblepromoterofbreastcancer inhumans. Pregnancy Termination Historically, pregnancy was of concern to surgeons primarily becausetheriskofexcesshemorrhageandshockwithmastectomywasincreasedgreatlyinthegravidstate. Billrothadvocated prematureinductionoflaborforthisreasonbutdidnotfind that abortion contributed to cure. More contemporary commentatorshavearguedthatthestrikingriseinestrogenproduction during pregnancy is of sufficient concern to warrant pregnancy termination and that future pregnancy avoidance should be an important principle of continuing care. Indeed, althoughmanycliniciansthinkthatlocalizedbreastcancerin thefirsttrimesterisavalidreasontorecommendtermination, reports by Peters and Rosemond illustrate that therapeutic abortionhasnoeffectonsurvival,andthepresenceofafetus doesnotcompromisepropertherapyinearlystages. Therapeutic abortion is not currently believed to be an essential component of effective treatment of early disease despite the theoretic advantage of removing the source of massive estrogen production. It is critically important to emphasize that treatment of breastcancershouldnotbedelayedprovidedtherearenomajor obstetricissues. Inthefirst trimester of pregnancy, the termination can be accomplished bysuctioncurettageoftheuterus;laterinpregnancy,terminationisaccomplishedbydinoprostone(Prostin) suppositories, oxytocin (Pitocin) administration, hysterotomy, or hysterectomy. Continued gestation represents no threat to thefetus,andtheriskoftransplacentalmetastasestothefetus isnegligible. Tamoxifen Tamoxifen citrate is a nonsteroidal weak estrogen that has foundsuccessfulapplicationsforeachstageofbreastcancerin the treatment of selected patients. For those who continue to ovulate and who are desirous of future childbearing, it has been common practice to recommend a waiting period of 2 years after the diagnosis of breast cancer before attempting to conceive because most recurrences occur within the first 2 years of diagnosis.

Thebasal-likesubtypeofbreast cancer was named because of the similarity in expression pattern of this subtype to that of basal epithelia cells. Metastases From Extramammary Tumors the most common primary site of an occult extramammary tumor is the lung. In those previously diagnosed, melanoma,prostate,cervix,uterus,andurinarybladderarethe most common sites. Overexpression or amplification has been shown to correlate withapoorprognosis;however,thestudiesdifferwithregard to the method of detection used and the interpretation of results. Generally, these have overall better prognosis than the other groups currently identified. Carcinomas in the breast parenchyma associated with Paget disease are categorized based on the size and characteristics of the parenchymal disease, although the presence of Paget disease should still be noted. Excisional biopsy of a lymph node or biopsy of a sentinel node, in the absence of assignment of a pT, is classified as a clinical N (eg, cN1). The use of postmastectomy chest-wall irradiation in these patientsmayalsobeconsidered. The guiding principle at this time was centered on the belief that canceroriginatesinthebreastandspreadsinastepwisefashion to the regional lymph nodes first and then to distant sites. Removalofallthebreasttissue,pectoralmuscles,andaxillary contents was the standard surgical treatment. From 2015 National Comprehensive Cancer Network guidelines relating to adjuvant therapy of breast cancer available at Breast-conservation Therapy Theshifttowardlessradicalsurgeryatthetimeofmastectomy occurred for several reasons. As earlier diagnosis of breast cancer with smaller tumors and less involvement of pectoral musclesoccurred,theneedforradicalproceduresdecreased. In addition, even with radical mastectomy, not all patients were cured and, although regional recurrences were low, patients diedofdistantdisease. Themorbidityoftheradicalmastectomy was well documented, including lymphedema, immobility of theshoulder,anddisfigurement. In breast-conserving surgery, a wide-local excision is performed with excision of the tumor and a 1- to 2-cm rim of normaltissue. Thesixrandomizedtrials differed with respect to the type of wide-local excision performedandwithrespecttotumorsizeinthepatientswhowere randomized. IntheInsitutGustaveRoussytrial,the"tumorectomy" performed was removal of the tumor and a 2-cm margin of normaltissue. No difference was seen in the incidence ofcontralateralbreastcancerorasecondmalignantneoplasm that was not breast cancer. Mostfailuresinthe treated breast can be salvaged with mastectomy, which can resultin70%survivalat5years.

Morerecently,dataonhypofractionation,whichincreases the daily dose and shortens the radiation therapy time, have beenreportedanddemonstrateequivalencetostandardradiationtechniques. The question of whether lumpectomy alone would yield similar results has been addressed through randomized trials.

Recentresearch has shown that many individuals are fearful of burdening their family members emotionally, physically, and financially during their final days.

There are many tasks that a patient should have the opportunity to accomplish in the time before death. Identification and treatment of psychosocial problems, including depression and anxiety, should involve interventions and expertise that will offer optimal care to the patient and family. As noted earlier, pharmacologic interventions are oftennecessarybutshouldbeconsideredincombinationwith psychologicalcounseling,supportiveinterventions,andeducationforthepatientandfamily. Determinationoftheappropriatereferraldependsinlargepartonthetypeandmagnitudeof the psychosocial or psychological disruption, as well as the extent to which this diagnosis interfaces with physical symptomatologysuchaspainorfatigue. Optimalprogramsinclude a team consisting of psychiatry, psychology, social work, and chaplain services. The health care team has an opportunity through the period of anticipatory grieving to assess and monitor the family and to identify risk factors indicating the need for more intensive intervention. An understanding of the spectrum of grief and the nature of "normal" grief is essential for providers to effectively support grieving families, identify abnormal reactions, and intervene. Obstruction may be secondary to extrinsic compression of the small bowel or hypoperistalsis caused by mesenteric and bowel surface implants. In most cases, nausea and vomiting can be relieved by conservativemeasures,andintestinalsymptomsusuallyresolve after primary cytoreductive surgery and multiagent cisplatinbased cytotoxic chemotherapy. Several therapeuticstrategieshavebeenusedinthesepatients,suchas includingretreatmentwithcisplatinorcarboplatinortheuse of paclitaxel, hexamethylmelamine, oral etoposide, tamoxifen, gemcitabine,liposomaldoxorubicin,vinorelbine,ortopotecan. Unfortunately, in patients previously treated with cisplatin, other therapeutic agents are not likely to be effective in relieving symptoms of bowel obstructionorascites. When surgery is indicated, the type of surgery depends on the extent of the disease as well as on the number and location of obstructions. Becausethe successofsecondarycytoreductiondependsonthechemosensitivityoftheresidualdiseasepresentafterdebulkingsurgery, intestinal bypass is generally preferable rather than resection becausemostpatientspresentaftermultiplefailedattemptsat cytotoxic therapy resulting in chemotherapy-resistant cancer.

Because dyspnea may indicateapoorerprognosisandshorterintervaltodeath,addressing this symptom is paramount to enhancing QoL in the time periodneardeath. Dyspnea may result from a combination of three different complications:(1)obstructivepathologysuchaspleuraleffusions, (2) cancer cachexia or malnutrition and weakness, and (3) an increase in ventilator requirements such as metabolic acidosis or anemia. Perhaps gynecologic oncologists most frequently encounter this tumor effect in the ovarian cancer patients because the dyspnea may be secondary to pleural effusions. It is suggested that thoracocentesis and chemical pleurodesis be reserved for palliative situations in which chemotherapy or other treatments are not likely to reverse the effusions. Benzodiazepines as well as oxygen therapy may also have a role in control of dyspnea, although evidenceislacking. Finally,somehaveadvocatedactivitymodifications to prevent the onset of dyspnea, which may involve caregiverinstructiontotailoractivitiesofdailyliving. Inrarecases,thecolon may be encased in tumor, necessitating a colostomy with or withoutbypasssurgery. Sadly,multiplesitesofobstructionare common in patients with recurrent epithelial ovarian cancer. In inoperable cases or situations when the patient or oncologist decidestoproceedwithmedicalorconservativemanagement, several options exist. Inthelastmonthoflife, this combined medical and conservative approach decreased pain,nausea,drymouth,thirst,dyspnea,feelingsofabdominal distention, and drowsiness in the palliative setting. In such cases, an ileostomy or even a proximal jejunostomy may be necessary to provide adequate intestinal diversion. On the contrary, if the extent of disease is so great that the morbidity of intestinal surgery seems excessive, stomach decompression with a gastrostomy may be effective in palliating symptoms of obstruction and ascites such as pressure, nausea, vomiting, andpain. Whenthestomachandanteriorabdominalwallare not involved with tumor, drainage tubes can often be placed percutaneously,thusavoidingthemorbidityofalaparotomy. With careful attention to nutrition, chemosensitivity or resistance of disease, and the sites of intestinal obstruction, some degree of palliation can generally be obtained with surgery,chemotherapy,orgastricdecompression.
