Thisrepresentsthethresholddoseatwhichstochastic effects (eg, mental retardation, organ malformation) couldmanifest. The complexity of the management of Hodgkin disease during pregnancy cannot be overstressed. Splenectomy is often performed during these staging procedures, and no contraindication in pregnancy is known. Thepurposeofstagingwith thisdiseaseistoachievethebestdifferentiationbetweenthose curable with local therapy (radiation) and those who require systemictherapy(chemotherapyorradiation)forcure. Treatmentisobviouslyeasierifthepregnancyisterminated, but that may not be an option. Current data suggest that the courseofHodgkindiseasedoesnotseemtobeaffectedbyan ongoing pregnancy. Other studies have also noted a survival rateofpregnantwomenwithHodgkindiseasecomparablewith that of nonpregnant patients with Hodgkin disease. Hodgkin lymphoma is not associated with an increase in miscarriage, stillbirths, or congenital anomalies unless treatment is started in the first trimester. In early-stagedisease,thelymphoidareasthatneedtobeirradiated include the mediastinum, Waldeyer ring and axilla (ie, mantlefield),andtheparaaorticareaandsplenicpedicle(spade field). When necessary, total nodal irradiation includes the pelvis(invertedYfield),asillustratedinFig. Pregnant women with Hodgkin lymphoma present with typical manifestations, with painless enlargement of lymph nodes above the diaphragm, usually the cervical, submaxillary, or axillary nodes. A, Two-field technique, with a small extension to include the splenic pedicle, used in splenectomized patients. The roleofstaginglaparotomyinHodgkindiseaseisdiminishing, and if necessary, it should be delayed until after delivery, at which time bilateral oophoropexy can be performed. Pohlman and Macklis carefully reviewed previously publishedguidelinesforHodgkindiseaseassociatedwithpregnancy andhaveproposedthefollowingmanagementscheme,which theauthorofthischapterhasendorsed(Fig. Theearlier thepregnancy,thestrongertherecommendationforpregnancy termination so that proper staging and treatment can begin. Thosefirst-trimesterpatientswithBsymptoms,bulky or advanced-stage disease, or rapid progression have an indication to initiate treatment immediately and should undergo therapeutic abortion. If the mother does not wish to sacrifice the pregnancy, single-agent vinblastine, which has a 7% anomaly rate when used in the first trimester, should be administered until the second trimester or until significant disease progression. Delivery should be delayed as long as possible after the last dose of chemotherapy (before the next dose) to decrease the risk of marrow suppression in the neonate. Itmaybeworthwhileto consider a cesarean section so that surgical staging can be performedatthesametime. Postchemotherapy-involved field radiation therapy can bepostponeduntilafterdeliverybutshouldbeinitiatedwithin 9weeksafterthelastcycleofchemotherapy. Mantleandspade fieldradiotherapywithextensiveabdominalshieldingisalsoan acceptablealternativeuntilthethirdtrimester,whentheuterus starts to impinge on the field. TwelvewomenwerediagnosedwithHodgkin disease before conception, 10 during pregnancy, and 27 after delivery or pregnancy termination. No statistically significant differenceinstageatdiagnosis,maternaloutcome,orpregnancy outcomewasidentifiedbetweenanyofthesesubgroupsandthe similar control group. It should be noted that 16 patients receivedradiotherapywhilepregnant,andfivereceivedcombinationchemotherapyandradiotherapywhilepregnant. Oftheremainingninewomen,mostreceivedone oftheaforementionedregimensduringthefirsttrimesterand either had therapeutic abortions or experienced spontaneous abortions,deliveringfetuseswithmultipleanomalies. In a study from Stanford University, the outcome of 17 pregnanciesassociatedwithHodgkindiseasebetween1987and 1993wasreported. Excludingfourwomenwhohadatherapeutic orspontaneousabortion,nocongenitalanomalieswerenoted atdelivery,andallchildrenwerereportedtobehealthyatthe time of last follow-up. The chromosomal analyses of all three children were normal, andatmorethan1year,5years,and7yearsoffollow-up,all threemothersandchildrenremainhealthy. Because thediseaseisusuallywidespreadwhenperipherallymphnodes have become involved, staging laparotomy is not used. Seven percent of pregnancies ended in therapeutic abortion, and4%ofwomenexperiencedaspontaneousabortion. Women who were diagnosed during the third trimester of pregnancy appeared to have a betteroutcomethanthosediagnosedearlier. Aviles and colleagues reviewed the outcome of both the motherandfetusin19pregnanciesbetween1975and1986. All patients received doxorubicin-based combination chemotherapy during pregnancy, including eight who received chemotherapy during the first trimester. Three mothers and their fetuses died during induction, and the 16 remaining women deliveredhealthyinfantsbetween35and39weeksofgestation. Eight of 12 mothers remained in complete remission 4 to 9 yearsafterdelivery,sevenmothersdiedoflymphoma,andone waslosttofollow-up. There have been seven patients exposed to rituximab during pregnancy,sixincombinationwithchemotherapy. Onepatient was exposed to rituximab during the first trimester, and the remainingsixhadthedruginitiatedduringthesecondtrimester.

Cumulative results from many studies utilizing lymphadenectomy in the surgical staging of cervix cancer have shownincreasedfrequencyofpositivepelvicnodes,asshown inTable3. Adenocarcinoma arisesfromtheendocervicalmucous-producingglandcells,and becauseofitsoriginwithinthecervix,itmaybepresentfora considerable time before it becomes clinically evident. These lesions are characteristically bulky neoplasms that expand the cervicalcanalandcreatetheso-calledbarrel-shapedlesionsof thecervix. Localrecurrenceismorecommonintheselesions,andthishas resultedinthecommonlyheldbeliefthattheyaremoreradioresistant than are their squamous counterpart. It seems more likely,however,thatthebulky,expansivenatureoftheseendocervical lesions, rather than a differential in radiosensitivity, accounts for the local recurrence. First, does this cell type carry a worse prognosis than squamousoradenosquamouscelltypes Allpatients were treated with a combination of intracavitary radium followedbyradicalhysterectomywithpelviclymphnodedissection. Inone respect, the adenocarcinomas showed a significant difference from the squamous cell cancers. The incidence of residual tumorinthehysterectomyspecimensafterintracavitarytreatment was much higher (30% vs. Kjorstad and Bond considered this a strong argument for surgical treatment of patientswithearlystagesofadenocarcinomaofthecervix. Mobergandcolleaguesreportedon251patientsatRadiumhemmet in Stockholm with adenocarcinoma of the uterine cervix. Combined treatment consisting of two intracavitaryradiumtreatmentswithanintervalof3weeksfollowedby a radical hysterectomy with pelvic lymphadenectomy done within 3 months gave improved 5-year survival in a nonrandomized series. Of these patients, 84 were treated with radiation therapy alone; 20 were treated with external and intracavitaryradiationfollowedbyhysterectomy,and56were treated with radical hysterectomy. After 5 years, 45% of the patients treated with radical hysterectomy had a recurrence. These recurrences were strongly correlated with lymph or vascularspaceinvasion,poorlydifferentiatedlesions,andlarger tumorsize. A higher proportion of cases with adenocarcinoma were of the lower stages and in the youngerpatientevenwithinagivenstage. After adjusting for multiple risk factors,survivalwasworstforadenosquamouscancercompared withsquamousandadenocarcinoma(71. Invasion is limited to measured stromal invasion with maximum depth of 5 mm and no wider than 7 mm Measured invasion of stroma no greater than 3 mm in depth and no wider than 7 mm Measured invasion of stroma greater than 3 mm and no greater than 5 mm and no wider than 7 mm Ia1 Ia2 the depth of invasion should not be more than 5mm taken from the base of the epithelium, surface or glandular, from which it originates. Stagingdoesnotdefinethetreatment plan, and therapy can be tailored to the architecture of themalignancyineachpatient. Itshouldbenotedthatallimaging modalities are more specific than sensitive in detecting nodal metastases. The accurate delineation of gross tumor volume suggeststhepotentialforsparingofnormaltissue. The 204 patients studied were divided into the following four groups: positive surgical staging with negative paraaortic imaging(n=16),negativesurgicalstaging(n=172),positive imagingwithoutsurgicalstaging(n=20),andnegativeimaging withoutsurgicalstaging(n=128). The role of surgical assessment of lymph nodes with extraperitoneal, laparoscopic, or roboticlymphadenectomyisexpanding. Some gynecologic oncologists believe that limited staging procedures are warranted on patients with advanced-stage cervical cancer to place patients on institutional or national group protocols. The status of paraaortic nodes should be knownbeforetreatmentisinitiatedinsuchcasestoplanappropriate modalities, such as the extent of the radiation field or concomitant chemotherapy. An extraperitoneal approach for removaloftheperiaorticnodesispreferredbymanyclinicians in an effort to reduce morbidity from the procedure. More advancedlesionshavebeeninvestigatedwitharetroperitoneal lymphadenectomy to determine the extent of disease before planningradiotherapyfields(Fig. The dashed line indicates the radiation field and the position of the uterus and cervix within the field.

Inmostinstitutions,theinitialmethodoftreatmentforlocally advanced disease is chemoradiation, both intracavitary and external radiographic therapy. The 5-year survival figures from two large series, one treated with radiotherapy alone and the other with surgery, are included here.

This agent may undergo further development, alone and in combination with bevacizumab, in ovarian and endometrialcancer. These proteins are serine/threonine kinases that act to control cell divisionthroughregulationofspindleassembly,chromosome separation, and centrosome maturation. Inaddition,Notch signaling through Dll4 appears to activate cell cycle arrest through a variety of mechanisms. Two major therapeutic avenues exist that block signaling through the Notch pathway. Thus, antibodies that target the Dll4 ligand have been developed to reduce toxicity. These compounds have demonstrated significant activity in in vivo models and are undergoing evaluation in early-phase clinical trials. This novel ligand drug conjugate combines folic acid with desacetylvinblastine hydrazide, a chemotherapeutic agent difficult to deliver systemically. Ofinterest,and in support of the target selectivity, there were few differences intheobservedtoxicitiesbetweenthetwoarms. Growingdata indicate that this protein may have a role in the peritoneal spread of ovarian cancer.
