Patients with uterine papillary serous cancers may benefit from adjuvant platinum-based chemoradiation.

OBJECTIVE: The coexistence of minimal uterine disease and extrauterine metastases is common in patients with uterine papillary serous carcinoma (UPSC). Only complete surgical staging accurately depicts the extent of this disease. The purpose of this study was to evaluate different therapeutic options in surgically staged patients. METHODS: We retrospectively reviewed all patients with UPSC histologically limited in the uterus to the endometrium treated at our institution between 1987 and 2002. RESULTS: Twenty-three (45%) cases were International Federation of Gynecology and Obstetrics (FIGO) stage IA, seven (15%) were stage IIIA, one (2%) was stage IIIC, and nine (18%) stage IV. Additionally, 11 of these 51 patients (21%) were diagnosed with two cancers: a stage IA UPSC and concomitant advanced stage serous cancer of the ovary, fallopian tube, or peritoneum. Stage IA patients with no cancer in the hysterectomy specimen (defined as no residual uterine disease) had no recurrences (n = 10) regardless of treatment. There was a trend toward increased survival in stage IA patients with residual uterine disease who were treated with chemoradiation (concomitant vaginal brachytherapy and platinum-based chemotherapy). There were no recurrences in patients with locoregional disease (stages IA-IIIA) who received chemoradiation. All patients with advanced stage UPSC (stage IIIC or IV or two primary cancers) did poorly regardless of treatment. CONCLUSION: Our findings suggest that stage IA patients with no residual uterine disease may be observed. Stage IA patients with residual uterine disease may benefit from chemoradiation. More effective treatment needs to be identified for advanced stage UPSC.

Diagnosis and treatment of epithelial ovarian cancer.

Epithelial ovarian cancer is a highly curable disease when diagnosed in an early stage. Unfortunately, treatment for advanced stage disease is mainly palliative. This article will review new developments in the diagnosis of ovarian cancer involving diagnostic imaging techniques and circulating tumor markers. It will discuss the current role of surgery in the treatment of the disease, including cytoreductive surgery, interval debulking surgery and surgery following neoadjuvant chemotherapy. It will evaluate the currently available chemotherapy treatments for epithelial ovarian cancers and present new developments in the medical management of this disease.

Cancer screening in a high risk population: a clinical trial.

The purpose of this paper is to report the results of screening high risk women for ovarian cancer using endovaginal ultrasound (EVUS), color flow Doppler and cancer antigen (CA) 125. A total of 252 women were recruited with a family history of ovarian cancer in at least 1 first-degree relative. All women underwent a pelvic examination and EVUS twice during the first year and annually thereafter. Of 210 premenopausal women in the study, 14 underwent surgery. Of these, 2 were based on the endovaginal ultrasound (US) results and proved to be false-positive. There were 48 postmenopausal women who underwent 9 operations. Of these, 2 were stimulated by finding a thickened stripe on EVUS, and proved to be endometrial carcinomas. There were 2 ovarian cancers, both advanced, 1 colon cancer and 1 renal cell cancer. Of the women, 6 had a history of breast cancer and 11 more developed it during the study. This high-risk population has a very high prevalence of breast cancer, and mammography must be a part of ovarian cancer screening programs.

Nongenetic screening of ovarian malignancies.

Ovarian cancer is the leading pelvic reproductive organ cancer health hazard for American women. Seventy percent of women are not diagnosed until the disease is in an advanced stage because of a lack of early warning signals and effective early detection techniques. Understanding the risk factors for sporadic ovarian cancer and the recently recognized inherited susceptibility for ovarian cancer associated with BRCA1 and BRCA2 gene mutations may allow physicians to identify women who might benefit from prophylactic oophorectomy. Current early detection techniques, including serum CA-125 levels and endovaginal ultrasound studies, are of limited value. Strategies to reduce the risk of ovarian cancer in women with increased risk include the use of oral contraceptives and tubal ligations in addition to prophylactic oophorectomy.

Associations between smoking and adenocarcinomas and squamous cell carcinomas of the uterine cervix (United States).

OBJECTIVES: Few studies of smoking and cervical carcinoma have addressed the rare cervical adenocarcinomas or used DNA-based tests to control for human papillomavirus (HPV) infection. METHODS: This multicenter case-control study included 124 adenocarcinoma cases, 307 community controls (matched on age, race, and residence to adenocarcinoma cases), and 139 squamous carcinoma cases (matched on age, diagnosis date, clinic, and disease stage to adenocarcinoma cases). Participants completed risk-factor interviews and volunteered cervical samples for PCR-based HPV testing. Polychotomous logistic regression generated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for both histologic types. RESULTS: Eighteen percent of adenocarcinoma cases, 43% of squamous carcinoma cases, and 22% of controls were current smokers. After control for HPV and other questionnaire data, adenocarcinomas were consistently inversely associated with smoking (e.g. current: OR = 0.6, 95% CI 0.3-1.1; > or = 1 pack per day: OR = 0.7, 95% CI 0.4-1.3), while squamous carcinomas were positively associated with smoking (e.g. current: OR = 1.6, 95% CI 0.9-2.9; > or = 1 pack per day: OR = 1.8, 95% CI 1.0-3.3). Results in analyses restricted to HPV-positive controls were similar. CONCLUSION: Smoking has opposite associations with cervical adenocarcinomas and squamous carcinomas. Although both histologic types are caused by HPV and arise in the cervix, etiologic co-factors for these tumors may differ.

Evaluation of self-collected cervicovaginal cell samples for human papillomavirus testing by polymerase chain reaction.

As human papillomavirus (HPV) becomes accepted as the central cause of cervical cancer, longitudinal studies are shifting focus away from causality to a more detailed investigation of the natural history of HPV infections. These studies commonly require repeated samples for HPV testing over several years, usually collected during a pelvic exam, which is inconvenient to the participants and costly to the study. To alleviate the inconvenience and cost of repeated clinic visits, it has been proposed that women collect cervicovaginal cells themselves, hopefully increasing participation in the natural history studies. We evaluated the technical feasibility of self-collection of cervicovaginal cells using a Dacron swab for HPV DNA detection. We compared the self-collected swab sample and two clinician-administered swab samples (one from the endocervix and another from the ectocervix) from a total of 268 women participating in a case-control study of adenocarcinoma and squamous cell carcinomas of the uterine cervix (111 cases and 157 controls). HPV DNA was detected and genotyped using an L1 consensus PCR assay. The overall agreement between the clinician- and self-collected swabs was excellent [88.1%; kappa = 0.73 (95% confidence interval (CI), 0.61-0.85)]. The correlation was highest between the two clinician-administered swabs [kappa = 0.81 (95% CI, 0.69-0.93)] but was still excellent when comparing either clinician-administered swab to the self-administered sample [kappa = 0.75 (95% CI, 0.63-0.87) and 0.67 (95% CI, 0.55-0.79) for ectocervix and endocervix, respectively]. The type-specific agreement between samples was higher for high-risk, or cancer-associated, HPV genotypes than for low risk, noncancer-associated HPV genotypes when comparing the self-administered swab sample to the clinician-administered swab sample (kappa = 0.78 for high-risk versus 0.66 for low-risk HPV infections, t = -1.45, P = 0.15). The decrease in agreement for low risk types was largely attributable to an increased detection of these types in the self-administered sample (McNemar's chi2 = 6.25, P = 0.01 for clinician- versus self-administered swab comparisons). The agreement did not vary significantly by age, menopausal status, case status, or clinic center. We have demonstrated that a self-collected Dacron swab sample of cervicovaginal cells is a technically feasible alternative to clinician-administered cervical cell collection in natural history studies of HPV and cervical cancer.

Novel embryonic genes are preferentially expressed by autonomously replicating rat embryonic and neointimal smooth muscle cells.

We sought to identify and characterize the expression pattern of genes expressed by smooth muscle cells (SMCs) during periods of self-driven replication during vascular development and after vascular injury. Primary screening of a rat embryonic aortic SMC-specific cDNA library was accomplished with an autonomous embryonic SMC-enriched, nonautonomous adult SMC-subtracted cDNA probe. Positive clones were rescreened in parallel with embryonic SMC-specific and adult SMC-specific cDNA probes. We identified 14 clones that hybridized only with the embryonic cDNA ("emb" clones), 11 of which did not share significant homology with sequences in any of the databases. Five of these novel emb genes (emb7, emb8, emb20, emb37, and emb41) were selectively and only transiently reexpressed in vivo by neointimal SMCs during periods of rapid replication. The emb8:embryonic growth-associated protein (EGAP), which was studied the most extensively, was expressed at high levels by cultured, autonomously replicating embryonic and neointimal SMCs but was detected only at low levels even in mitogenically stimulated adult SMCs. Finally, the administration of antisense EGAP oligonucleotides markedly attenuated embryonic and neointimal SMC replication rates. We suggest that autonomous replication of SMCs may be essential for normal vascular morphogenesis and for the vascular response to injury and that these newly identified "embryonic" genes may be part of the molecular machinery that drives this unique growth phenotype.

Use of hormone replacement therapy and adenocarcinomas and squamous cell carcinomas of the uterine cervix.

INTRODUCTION: Exogenous hormones may influence the development of cervical adenocarcinomas. Incidence rates of adenocarcinomas and use of noncontraceptive hormones have increased since the 1970s, but few studies have investigated this potential relationship. METHODS: We conducted a multicenter case-control study of 124 women with adenocarcinomas, 139 women with squamous cell carcinomas matched on age, diagnosis date, clinic, and stage of disease (in situ or invasive) to adenocarcinoma cases, and 307 healthy community controls who were also matched on age, ethnicity, and residence to adenocarcinoma cases. Participants completed in-person interviews regarding exogenous hormone use before diagnosis and other risk factors and volunteered cervical samples for human papillomavirus (HPV) testing via a PCR-based method. Odds ratios (ORs) with 95% confidence intervals (CIs) estimated relative risks. RESULTS: Only 13 adenocarcinoma cases (10.5%), 7 squamous carcinoma cases (5%), and 20 controls (6.5%) had used noncontraceptive hormones for menopausal symptoms, irregular periods, or disease prevention; most use was short-term, former use. Ever-use was associated with adenocarcinomas (OR = 2.1, 95% CI 0.95-4.6) but not squamous carcinomas (OR = 0.85, 95% CI 0.34-2.1). No trends were seen with duration of use or ages at first use, but unopposed estrogens were positively associated with adenocarcinomas (OR = 2.7). Unopposed estrogens remained associated with adenocarcinomas (OR = 2.0) when analyses were restricted to the HPV-positive controls. Menopausal status was not associated with adenocarcinomas or squamous carcinomas and did not modify the other associations. CONCLUSION: Although small numbers warrant tentative conclusions, exogenous estrogens, especially unopposed estrogens, were positively associated with adenocarcinomas. Noncontraceptive hormones were negatively but weakly associated with squamous carcinomas.

The oestrogen receptor (ER) in vulva, vagina and ovary.

The oestrogen receptor (ER) has been identified in normal and neoplastic epithelia of the vulva, vagina and ovary using biochemical, immunohistochemical (IHC) and molecular techniques. Its presence has not translated into effective antineoplastic therapy for malignancies arising from these sites.

Neoadjuvant chemotherapy for advanced ovarian cancer: long-term survival.

PURPOSE: The aim of this study was to compare the progression-free and overall survivals of women with advanced ovarian cancer treated with neoadjuvant chemotherapy followed by surgery with those treated conventionally with cytoreductive surgery followed by cytotoxic chemotherapy. MATERIALS AND METHODS: Fifty-nine consecutive women with advanced malignancies compatible with ovarian cancer based on (1) physical examinations, (2) computerized tomography scans, and (3) cytologic or histologic specimens and treated with platinum-based combination chemotherapy, i.e., neoadjuvant chemotherapy, were retrospectively reviewed. Forty-one subsequently underwent cytoreductive surgery. Their overall and progression-free survivals were compared to those of 206 consecutive women with Stage IIIC and IV epithelial ovarian cancers treated with conventional cytoreductive surgery followed by platinum-based combination chemotherapy during the same era. RESULTS: No statistical difference was observed in overall survival (P = 0.1578) or in progression-free survival between the group treated with neoadjuvant chemotherapy and the conventionally treated group (P = 0.5327) despite the neoadjuvant chemotherapy patients being statistically older (median age 67 years [range 44 to 85 years] vs a median age of 60 years [range 19 to 79 years] for conventionally treated patients; P < 0. 001) and having a statistically poorer performance status (P < 0. 001) than the conventionally treated group. Women undergoing cytoreductive surgery following neoadjuvant chemotherapy had a statistically improved overall survival (P < 0.0001) compared to those who did not undergo surgery. CONCLUSIONS: Neoadjuvant chemotherapy does not compromise the survival of women treated for advanced ovarian cancer. Prospective randomized trials comparing neoadjuvant chemotherapy to conventional therapy to determine quality of life experiences and cost/benefit outcomes are now appropriate for women presenting with advanced ovarian cancer.

Serous adenocarcinoma of the uterus presenting as paraneoplastic cerebellar degeneration.

Paraneoplastic cerebellar degeneration is a rare complication of cancer and is most frequently associated with lung, ovary, and breast cancers as well as Hodgkins lymphoma. A 74-year-old female with a past history of breast cancer presented with vomiting, ataxia, slurred speech, and dizziness. Her serum chemistry, thyroid and liver function tests, acetylcholine antibodies, serum cortisol, CT, and MRI imaging were all normal. Serum testing for anti-YO antibodies was positive. Further evaluation including CT of the abdomen and pelvis revealed endometrial thickening. Subsequently, an endometrial biopsy showed a poorly differentiated serous adenocarcinoma. Surgical staging was consistent with a stage IIIc serous adenocarcinoma of the uterus. The risk factors, symptoms, signs, differential diagnosis, and clinical and antibody associations of the paraneoplastic cerebellar degeneration syndrome are reviewed. In addition, an efficient approach to the diagnostic evaluation of such patients is proposed.

Adenocarcinoma in situ of the cervix: management and outcome.

OBJECTIVE: The aim of this study was to review the management and outcome of patients with adenocarcinoma in situ of the cervix and to evaluate the significance of endocervical cone margin status in these patients. METHODS: A retrospective review of records between January 1988 and December 1996 identified 40 patients with adenocarcinoma in situ on cone biopsy for whom complete information was available. The median follow-up was 38 months. RESULTS: The mean age was 37 years, and the mean parity was 1.3. Fifty-three percent of the patients had prior abnormal cervical cytology. The initial Pap smear that led to the patient's referral was abnormal in 39 (98%). Initial cervical biopsies showed adenocarcinoma in situ and/or glandular dysplasia in 28 (70%), squamous dysplasia in 2 (5%), chronic inflammation in 2 (5%), and no pathologic changes in 2 (5%) patients. Initially no biopsies were performed in 3 (7.5%) patients and the results of 3 (7.5%) biopsies were unknown. Subsequently, all patients had cone biopsies. The endocervical margins were positive for glandular abnormalities in 24% of cold knife cones (CKC), 75% of LEEPs, and 57% of laser cones. The ectocervical margins were positive for squamous and/or glandular abnormalities in 8% of CKCs, 13% of LEEPs, and 57% of laser cones. ECCs above the cone were obtained in 28 patients, and only 1 (3%) was positive. The definitive treatment was hysterectomy in 27, repeat cone in 5, and no additional therapy in 8 patients. The pathology showed residual disease in 44% of treated patients. From 16 cone biopsies with negative margins who had subsequent treatment, there was residual disease in 5 (31%) specimens (1 adenocarcinoma in situ, 1 mild glandular dysplasia, 3 glandular atypia). From 16 cones with positive margins who had subsequent treatment, there was residual disease in 9 (56%) specimens. The patients with negative ECCs above the cone regardless of margin status had residual disease in 58% of treated specimens. CONCLUSION: Women with adenocarcinoma in situ of the uterine cervix had residual disease in 31% of cases with negative margins in cone biopsies and/or with negative ECCs and in 56% of cases with positive endocervical margins. LEEP cones had higher rate of positive endocervical margins (75%) compared to CKC (24%) and laser cone (57%). If maintaining reproductive capacity is desired, we would recommend CKC; however, this does not guarantee absence of the disease.

Well-differentiated mucinous carcinoma of the ovary and a coexisting Brenner tumor both exhibit amplification of 12q14-21 by comparative genomic hybridization.

Although the coexistence of mucinous ovarian neoplasms and Brenner tumors is well established, the histogenesis and developmental relationship between the two remain unknown. We used comparative genomic hybridization to analyze two such tumors occurring simultaneously, one in each ovary, in a patient. Amplification of 12q14-21 sequences was found in both tumors; in addition, both tumors also had other, different changes, four identified in the Brenner tumor and six in the mucinous carcinoma. The occurrence of the same genetic alteration in both tumors in this woman suggests that the mucinous carcinoma and Brenner tumor may be clonally related, i.e., one arose from the other by means of metastatic spreading of transformed cells from one ovary to the other. An alternative explanation is that some unknown, putative tumorigenic agent induced similar and synchronous pathogenetic changes in the epithelium of both ovaries. The phenotypic differences between the tumors are presumably attributable to the other unique genetic abnormalities identified in both tumor types.

Risk factors for rapid-onset cervical cancer.

OBJECTIVES: The current study was designed to elucidate risk factors associated with the development of cervical cancer during the course of routine Papanicolaou smear screening (rapid-onset cervical cancer). STUDY DESIGN: Four hundred eighty-three women diagnosed with invasive cervical cancer, representing 73% of all such tumors diagnosed in Connecticut between 1985 and 1990, were studied. Papanicolaou smear screening and risk factor information was obtained by questionnaire and physician record review. Results from human papillomavirus deoxyribonucleic acid testing by polymerase chain reaction of tumor samples were available for 278 study participants. Prediagnostic Papanicolaou smear slides were reviewed for 67% of cases with a screening history. Screening history information, slide review, and questionnaire data were used to classify women as having rapid-onset cervical cancer (n = 43), possible rapid-onset cervical cancer (n = 111), or normal-onset cervical cancer (n = 329). RESULTS: Compared with normal-onset cases, rapid-onset cases tended to be younger (P =.001) and were more likely to be white (P =.002), diagnosed with adenocarcinomas or adenosquamous carcinomas (P =.001), and diagnosed with early-stage disease (P =.001). Cases diagnosed as possible rapid-onset disease tended to have a profile that was intermediate to that observed for rapid-onset and normal-onset cases. Human papillomavirus deoxyribonucleic acid was detected in 75.2% of cases tested. Compared with women who tested positive for human papillomavirus type 16 or other, those positive for human papillomavirus type 18 had a relative risk for rapid-onset disease of 1.6 (95% confidence interval 0.52-4.9). No significant association was observed between type 18 and possible rapid-onset disease when possible rapid-onset cases were compared with women diagnosed with normal-onset cervical cancer (relative risk 0.67, 95% confidence interval 0.29-1.6). Oral contraceptive use, cigarette smoking, number of pregnancies, and a maternal history of cervical cancer were not significantly associated with rapid-onset disease. CONCLUSIONS: Results from this study suggest that the risk factors associated with the development of rapid-onset cervical cancer are similar to those for normal-onset disease.

Oral contraceptives as risk factors for cervical adenocarcinomas and squamous cell carcinomas.

To assess the hypothesis that oral contraceptives (OCs) increase the risk of cervical adenocarcinomas, we conducted a six-center case-control study of 124 patients with adenocarcinomas, 139 with squamous cell carcinomas, and 307 population controls. Women between the ages of 18 and 69 who were newly diagnosed with cervical adenocarcinomas between 1992 and 1996 were eligible. Healthy female controls and a second case group of incident cervical squamous cell carcinomas were matched to the adenocarcinoma cases. All participants were interviewed regarding OCs, other risk factors for cervical carcinoma, and utilization of cytological screening, and a PCR-based test determined HPV genotype of cervical samples for both case groups and controls. Use of OCs was positively and significantly associated with adenocarcinomas and positively but weakly associated with squamous cell carcinomas. Associations between OCs and invasive adenocarcinomas (n = 91), squamous cell carcinoma in situ (n = 48), and invasive squamous cell carcinomas (n = 91) disappeared after accounting for HPV infection, sexual history, and cytological screening, but a positive association remained between current use of OCs and cervical adenocarcinoma in situ (n = 33). This association persisted after stratification by screening and sexual history and after restriction according to HPV status, but small numbers made it difficult to exclude detection bias, selection bias, or residual confounding by HPV as potential explanations Current OC use was associated with cervical adenocarcinomas in situ, but we saw no other evidence that OCs independently increase the risk of cervical carcinomas.

CA 125 may not reflect disease status in patients with uterine serous carcinoma.

BACKGROUND: Although CA 125 level correlates with response to therapy in patients with serous carcinoma of the ovary, the utility of CA 125 in patients with high risk or metastatic endometrial carcinoma has not been established. METHODS: CA 125 was tested as a marker of disease status in patients with endometrial serous carcinoma (SC) undergoing adjuvant chemotherapy. All patients received monthly intravenous chemotherapy with cisplatin, cyclophosphamide, and doxorubicin at standard doses (median number of courses, 6; range, 2-8 courses). Serum CA 125 was measured at diagnosis and before each course. After the completion of chemotherapy, patients were examined every 3 months and the CA 125 level was measured. RESULTS: A total of 220 serum specimens from 15 patients with invasive SC were analyzed. All five patients who died of disease had clinical or radiographic evidence of tumor, which CA 125 elevation did not precede or predict. One patient with advanced disease at staging never had an elevated CA 125 level but died of disseminated disease 14 months after diagnosis. At last follow-up, 3 patients who were without evidence of disease > 36 months from diagnosis had significant false-positive elevations in their CA 125 level (>50 u/mL) lasting 1, 2, and 4 months, respectively, during therapy. The sensitivity for advanced disease was only 57% at presentation. CONCLUSIONS: CA 125 may reflect advanced stage disease and portend a poor prognosis, but may not add information to that gained by history and physical examination, preoperative studies, or surgery that already is mandated by this high risk histology. This circulating marker appears to have limited utility in monitoring the effects of adjuvant therapy for SC, and may not predict recurrence in the absence of other clinical findings.

Effective treatment of stage I uterine papillary serous carcinoma with high dose-rate vaginal apex radiation (192Ir) and chemotherapy.

PURPOSE: Uterine papillary serous carcinoma (UPSC) is a morphologically distinct variant of endometrial carcinoma that is associated with a poor prognosis, high recurrence rate, frequent clinical understaging, and poor response to salvage treatment. We retrospectively analyzed local control, actuarial overall survival (OS), actuarial disease-free survival (DFS), salvage rate, and complications for patients with Federation International of Gynecology and Obstetrics (FIGO) (1988) Stage I UPSC. METHODS AND MATERIALS: This retrospective analysis describes 38 patients with FIGO Stage I UPSC who were treated with the combinations of radiation therapy, chemotherapy, total abdominal hysterectomy, and bilateral salpingo-oophorectomy (TAH/BSO), with or without a surgical staging procedure. Twenty of 38 patients were treated with a combination of low dose-rate (LDR) uterine/vaginal brachytherapy using 226Ra or 137Cs and conventional whole-abdomen radiation therapy (WART) or whole-pelvic radiation therapy (WPRT). Of 20 patients (10%) in this treatment group, 2 received cisplatin chemotherapy. Eighteen patients were treated with high dose-rate (HDR) vaginal apex brachytherapy using 192Ir with an afterloading device and cisplatin, doxorubicin, and cyclophosphamide (CAP) chemotherapy (5 of 18 patients). Only 6 of 20 UPSC patients treated with combination LDR uterine/vaginal brachytherapy and conventional external beam radiotherapy underwent complete surgical staging, consisting of TAH/BSO, pelvic/para-aortic lymph node sampling, omentectomy, and peritoneal fluid analysis, compared to 15 of 18 patients treated with HDR vaginal apex brachytherapy. RESULTS: The 5-year actuarial OS for patients with complete surgical staging and adjuvant radiation/chemotherapy treatment was 100% vs. 61% for patients without complete staging (p = 0.002). The 5-year actuarial OS for all Stage I UPSC patients treated with postoperative HDR vaginal apex brachytherapy and systemic chemotherapy was 94% (18 patients). The 5-year actuarial OS for Stage I UPSC patients treated with HDR vaginal apex brachytherapy and chemotherapy who underwent complete surgical staging was 100% (15 patients). The 5-year actuarial OS for the 20 Stage I UPSC patients treated with combinations of pre- and postoperative LDR brachytherapy and postop WART was 65%. None of the 6 surgically staged UPSC patients treated with LDR radiation and WART/WPRT developed recurrent disease. For patients with FIGO Stage IA, IB, and IC UPSC who underwent complete surgical staging, the 5-year actuarial DFS by depth of myometrial invasion was 100, 71, and 40%, respectively (p = 0.006). The overall salvage rate for local and distant recurrence was 0%. Complications following HDR vaginal apex brachytherapy included only Radiation Therapy Oncology Group (RTOG) grade 1 and 2 toxicity in 16% of patients. However, complications from patients treated with WART/WPRT, and/or LDR brachytherapy, included RTOG grade 3 and 4 toxicity in 15% of patients. CONCLUSION: Patients with UPSC should undergo complete surgical staging, and completely surgically staged FIGO Stage I UPSC patients can be effectively and safely treated with HDR vaginal apex brachytherapy and chemotherapy. Both OS and DFS of patients with UPSC are dependent on depth of myometrial invasion. The salvage rate for both local and distant UPSC recurrences is extremely poor. Complications from HDR vaginal apex brachytherapy were minimal.
