Nodes that are totally replaced by tumor may not be identified by mapping because of blockage of lymphatic channels by tumor, thereby resultinginafalse-negativeresult.

Stranderandassociatesshowedthat risk for cervical cancer rose significantly in previously treated women after age 50 years, with standardized incidence ratios comparedwithuntreatedwomenrangingfrom3to5.

Despiteearlyconcernsthathumoralimmunity would be insufficient to prevent infection, vaccine efficacy appears to approach 100%. Thebenefitofcervicalcancerprevention, whichmighttakedecadestobecomemanifest,isaugmentedby its ability to prevent genital warts, a concern for many young women. Because teen sexual activity is unpredictable,delayingvaccinationuntilgirlsaremoremature risks missing the vaccination window for many. Several countries have instituted organized vaccination programs, either mandatory or using a school-based opt-in mechanismwithhighuptake. Anaphylactic and vagal reactions may be fatal, so vaccination should only be administered in sites with ability to manage anaphylaxisandfainting. The duration of vaccine effectiveness is unclear, but antibodylevelsremainelevatedforseveralyearsaftervaccination. This is because many women of screening age were not vaccinated before initiating intercourse, so vaccine effectiveness is unclear. However,identificationofapparentprecancersinwomenwithcomorbidities that will be fatal in the medium term, before progression to symptomaticcancer,isnothelpful.

Afterreceiving5000cGy arrhythmia technology institute order clonidine in india, the patient with a large lesion should be reevaluated for an additional 1000 to 2000cGy of external radiation to reduced field. Newer treatment planning protocols using intensity-modulated radiation therapy may yield higher tumor control with less local normal tissue effects. Radiationtherapyaloneforlocallyadvancedvaginalcancers generate relatively poor outcomes because of predominantly local failures. Chemoradiation is standard of care for patients with locally advanced carcinoma of the cervix. Because the naturalhistory,histology,andriskfactorsaresimilarforvaginal cancer,chemosensitizationwithweeklycisplatinhasbeenrecommended in patients receiving radiation for advanced-stage disease.

Special Considerations Although one is often dealing with a radiosensitive neoplasm in a relatively radioresistant bed (the vagina), serious limitations exist.

Survival and Recurrence A study by Rutledge in 1967 reported 3- and 5-year survival ratesof42%and44%,respectively,forpatientstreatedprimarily with radiotherapy. Most of them received interstitial or intracavitary therapy or both; the addition of external-beam irradiation did not significantly increase survival or tumor control.

Womenwith stage I disease who were treated with surgery had a 5-year survival rate of 90% compared with 63% for patients treated with radiotherapy and 79% for patients treated with surgery andradiotherapy. Becauseofthe poor prognosis associated with advanced stage disease, these investigatorssuggestedroutineuseofcombinedchemotherapy andradiationasatreatmentstrategyforthesepatients. Vaginal cancers appear to behave similar to cervical or vulvar cancer by first recurring locally. More than 80% of patients with recurrent disease have pelvic recurrence noted clinically,andmostrecurrencesappearwithin2yearsofprimary therapy. Effective treatment for previously irradiated but locallyrecurrentorpersistentvaginalcancerpatientsrequires radical surgery (ie, pelvic exenteration). Most of the patients with recurrence in previously irradiated fieldsshowednoresponse;fiveoftheremaining15patientshad stabledisease. InApril1970,Herbst andScullyreportedsevencasesofprimaryvaginaladenocarcinoma in patients between the ages of 15 and 22 years. Becauseofthiscaseclustering,anepidemiologicstudyofthepatientsandtheirfamilies was initiated to identify associative factors.
Even in stage I disease blood pressure medication for diabetics generic clonidine 0.1 mg overnight delivery, only 44% of patients with clear cell carcinomas survive 5 years blood pressure stages order 0.1mg clonidine with amex. Photopulos and associates arrhythmia heart murmur order clonidine with a mastercard, in a review of their material, noted that their patients with this entity were older and tended to have a worse prognosis. They did note that patients with stage I clear cell carcinomas had a 5-year survival similar to that of patients with stage I pure adenocarcinoma of the endometrium. Multiple factors have been identified for endometrial carcinoma that have prognostic value (Table 5-4). Essentially all reports in the literature agree stage (extent of disease spread), grade of tumor, and depth of invasion are important prognostic considerations. Before 1988 endometrial cancer was clinically staged with stage assignments based on uterine size and clinical extent of disease. TumorGrade In addition to histologic type, pathologists assign a measure of tumor differentiation, known as grade, to endometrial cancers. Grade I lesions are well differentiated, are frequently associated with estrogen excess, closely resemble hyperplastic endometrium, and are generally associated with a favorable prognosis. Before this study, it was presumed most patients with endometrial cancer were at risk for nodal metastases and nearly all patients required some form of pelvic radiation therapy (either preoperatively or postoperatively). The study demonstrated important relationships between pathologic factors and risk of nodal disease. Approximately 75% of patients with endometrial cancer present with disease limited to the uterus (Table 5-7). For stage I disease, depth of tumor invasion into the myometrium is an important prognostic factor. The degree of myometrial invasion is a consistent indicator of tumor virulence (Figure 5-11). DiSaia and associates noted that recurrences were directly related to depth of myometrial invasion in patients with stage I cancer treated primarily with surgery (Table 5-8). Lutz and co-workers determined that the depth of myometrial penetration was not as important as the proximity of the invading tumor to the uterine serosa. Patients whose tumors invaded to within 5 mm of the serosa had a 65% 5-year survival rate, whereas patients whose tumors were more than 10 mm from the serosa had a 97% survival rate. The depth of myometrial invasion is associated with the other prognostic factors, such as the grade of the tumor. As noted by DiSaia and associates, the survival rate of patients with poorly differentiated lesions and deep myometrial invasion is poor in contrast to that of patients who have well-differentiated lesions but no myometrial invasion. This suggests that virulence of the tumor may vary considerably, and as a result, therapy should depend on the combination of prognostic factors. Location of the tumor within the endometrial cavity is important because tumors low in the cavity may involve the cervix earlier than fundal lesions. Cervical involvement is often a surrogate marker for extrauterine disease spread or for risk of local recurrence. There is a similar frequency of para-aortic nodal metastases: a 16% incidence from disease of the lower uterine segment and a 4% incidence when only fundal disease is present. It is well recognized that endometrial cancer can and frequently does metastasize to the adnexa.
