Abstract
OBJECTIVES Women with uterine clear cell carcinoma (UCCC) are at high risk of relapse. Adjuvant chemotherapy (CT) is often recommended, although its effectiveness remains controversial. Our objective was to evaluate treatment-related outcomes of patients with UCCC, particularly those treated with adjuvant CT. METHODS In this retrospective cohort study, patients diagnosed with UCCC at 2 academic cancer centers from 2000 to 2014 were included. Clinical, surgical, and pathological data were collected. Survival estimates were obtained using the Kaplan-Meier method and compared by log rank test. Multivariable analysis was used to determine the effect of CT and radiation therapy (RT) on overall survival (OS) and progression-free survival (PFS). RESULTS We included 146 patients with UCCC, with a median follow-up of 27 months (range, 1-160). Ninety-five (65%) patients presented with stage I to II disease and 51 (35%) with stage III to IV disease. Forty-six percent of patients with clinical stage I were upstaged after surgery: 29% were upstaged to stages III and IV. Thirty-one percent of patients with early-stage disease and 70% with advanced-stage received CT. Among recurrences, the majority had distant relapse in both early-stage (61.5%) and advanced-stage (96.3%) diseases. In both patients with early-stage and advanced-stage diseases, adjuvant CT did not improve OS or PFS. On multivariate analysis, CT was not a significant factor associated with improved PFS (hazard ratio [HR], 1.37; 95% confidence interval [CI], 0.69-2.71; P = 0.37) or OS (HR, 0.58; 95% CI, 0.24-1.38; P = 0.22), whereas RT was associated with improved PFS (HR, 0.51; 95% CI, 0.29-0.90; P = 0.02) and OS (HR, 0.19; 95% CI, 0.09-0.42; P < 0.001). CONCLUSIONS The high rate of upstaging after surgery highlights the importance of lymph node assessment. The high rate of distant recurrence questions the effectiveness of current CT regimens and warrants the development of novel systemic approaches. The role of adjuvant RT deserves further study.

Abstract
OBJECTIVE Because of the rarity of uterine clear cell carcinoma (UCCC), a National Cancer Data Base analysis was conducted to evaluate practice patterns and implications of adjuvant therapy. METHODS The National Cancer Data Base was queried for UCCC patients diagnosed from 1998 to 2011. Patients receiving neoadjuvant therapy, lacking surgical staging, or having follow-up time shorter than 6 months were excluded. Factors associated with utilization were assessed using logistic regression. To define the probability of receiving chemotherapy and radiotherapy (CT + RT), propensity scores with inverse probability of treatment weighting (IPTW) were calculated using multivariable logistic regression. Log-rank test and multivariable IPTW-adjusted Cox proportional hazards modeling were then conducted. RESULTS A total of 2504 patients were identified, with a median follow-up of 65.5 months. Most patients had FIGO (International Federation of Gynecology and Obstetrics) stage I to II UCCC (71.4%). Adjuvant RT alone, CT alone, or CT + RT was given in 35.3%, 9.5%, and 11.7%, respectively. Among those receiving RT, external beam was the most common modality (69.4%). Later year of diagnosis (>2005: odds ratio [OR], 4.42; 95% confidence interval [95% CI], 2.44-8.01), higher FIGO stage (IIIA-IIIC2: OR, 6.34; 95% CI, 3.93-10.24), larger tumor size (3.6-5.0 cm: OR, 3.40; 95% CI, 1.76-6.55), and lymph node dissection (OR, 4.22; 95% CI, 1.60-11.15) were associated with a higher chance of receiving CT + RT. With IPTW-adjusted multivariable analysis, CT + RT significantly decreased mortality risk in stage III to IVA patients (hazards ratio, 0.41; 95% CI, 0.22-0.77), trending toward benefit in stage I to II patients (hazards ratio, 0.53; 95% CI, 0.27-1.07). CONCLUSIONS In this hospital-based registry analysis of UCCC, adjuvant CT + RT significantly reduced the risk of death, reaching statistical significance for stage III to IVA patients.

Abstract
OBJECTIVE The aim of the study was to examine the patterns of care and the impact of chemotherapy and radiation on survival in women diagnosed with uterine clear cell carcinoma (UCCC). The primary outcomes of this analysis were receipt of treatment within 6 months of diagnosis and overall survival. METHODS AND MATERIALS Women diagnosed with UCCC from 2003 to 2011 were identified through the National Cancer Data Base. Standard univariate and multivariable analyses with logistic regression were performed. Kaplan-Meier survival analysis was used to generate overall survival data. Factors predictive of outcome were evaluated using the log-rank test and Cox proportional hazards model. RESULTS A total of 3212 patients were identified. Chemotherapy, radiation, and combination chemotherapy and radiation were administered in 23.3%, 19.7%, and 11.1% of women, respectively. After adjusting for age, race, socioeconomic status, facility type, stage, surgery, lymph node dissection, comorbidity index, period of diagnosis, and registry location, there was an association between combined chemotherapy and radiation (hazard ratio, 0.74; 95% confidence interval, 0.61-0.90) with improved survival. Adjuvant therapy was not associated with improved survival among patients with early-stage disease (stages I and II). Both chemotherapy and combined chemotherapy and radiation were associated with significantly improved survival among patients with advanced-stage disease (stages III and IV). CONCLUSIONS In patients with early-stage UCCC, adjuvant therapy was not associated with significantly improved survival. Chemotherapy and combination of chemotherapy and radiation were associated with improved survival in patients with advanced-stage UCCC.

Abstract
OBJECTIVE To assess the appropriate extent of surgical staging in women with clinically early stage uterine serous carcinoma (USC). METHODS We conducted a single-institution retrospective cohort study of all women with USC between 2007 and 2012. Treatment practices, outcomes, and factors affecting survival were analyzed using univariate and multivariate analysis. RESULTS Eighty-four patients were identified, 76 of whom were included in the analysis. Preoperative pathology correctly identified USC in 73.3% of cases. Surgical stage distribution was 44.7% stage I, 7.9% stage II, 31.6% stage III, and 15.8% stage IV. Women thought to have early stage disease preoperatively encompassed 84.2% (64) of the cohort. Fifty-two (81.3%) of these women with clinically early stage disease had complete surgical staging. Thirty-four (53.1%) were determined to have surgical stage I, and the remaining 30 (46.9%) had occult advanced stage disease. Median follow-up was 43.2 months. Univariate analysis found a significant increase in progression-free survival and overall survival for women with clinically early stage disease with positive lymphovascular space invasion (P < 0.001 and P = 0.002, respectively), positive peritoneal cytology (P = 0.022 and P = 0.04, respectively), early stage (P < 0.001 and P = 0.004, respectively), and elevated serum CA125 at diagnosis (P = 0.003 and P = 0.001, respectively). On multivariate analysis, early stage (hazard ratio [HR] 9.87; 95% CI 2.79 to 34.92, P < 0.001) and complete surgical staging (HR 2.96; 95% CI 1.05 to 8.37, P = 0.040) were associated with prolonged progression-free survival, while overall survival was not affected by complete surgical staging (HR 1.92; 95% CI 0.64 to 5.76, P = 0.79). CONCLUSION Complete surgical staging prolongs the progression-free survival of women with clinical early-stage uterine serous cancer. Although this does not extend to overall survival, this enables patients to have an improved quality of life with a longer interval without the burden of disease.

Abstract
Uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC) represent two rare subtypes that have an increased risk of recurrence and worse overall survival compared with the more common endometrioid endometrial cancers. Meaningful data in the form of prospective randomized trials is lacking for both advanced and early-stage UPSC and UCCC. Data extrapolated from prospective trials in advanced endometrioid endometrial cancer and retrospective trials on early-stage UPSC suggest that adjuvant platinum and taxane-based chemotherapy may provide a survival benefit for these patients. Future trials specifically examining UPSC and UCCC are needed to elucidate the optimal treatment regimen for these patients. Given the current data, the option of chemotherapy should be considered in treatment-planning discussions for all patients with UPSC and UCCC.

Abstract
PURPOSE OF REVIEW Uterine papillary serous carcinoma (UPSC) is a rare but aggressive subtype of endometrial cancer. Although it represents only 10% of all endometrial cancer cases, UPSC accounts for up to 40% of all endometrial cancer-related recurrences and subsequent deaths. The present article reviews the literature concerning the epidemiology, molecular pathogenesis and recent updates on management of UPSC. RECENT FINDINGS Women most often present with postmenopausal vaginal bleeding but may also be diagnosed by vaginal cytology. In women diagnosed with metastatic disease, ascites, omental implants or a pelvic mass may be present. Pelvic and extrapelvic recurrences occur frequently, with extrapelvic relapses being observed most commonly. Although few prospective trials exist, several retrospective series have demonstrated that optimal cytoreduction and adjuvant platinum/taxane-based chemotherapy with or without radiotherapy appears to improve survival. In addition, another approach to UPSC management may lie in targeted therapy. SUMMARY Women diagnosed with UPSC should undergo comprehensive surgical staging and an attempt at optimal cytoreduction. Platinum/taxane-based adjuvant chemotherapy should be considered in the treatment of both early and advanced-stage patients. Careful long-term surveillance is indicated as many of these women will recur. Prospective studies are needed to define the optimal treatment regimens and to study the role of targeted therapies in UPSC.

Abstract
Endometrial cancer is the most common gynaecological cancer in western countries. Radiotherapy remains the mainstay of postoperative management, but accumulating data show that adjuvant chemotherapy may display promising results after staging surgery. The prognosis of patients with metastatic disease remains disappointing with only one-year survival. Progestins represent an effective option, especially for those patients with low-grade estrogen and/or progesterone receptor positive disease. Chemotherapy using the combination of paclitaxel, doxorubicin, and cisplatin is beneficial for patients with advanced or metastatic disease after staging surgery and potentially for patients with early-stage disease and high-risk factors. Toxicity is a point in question; however, the combination of paclitaxel with carboplatin may diminish these concerns. In women with multiple medical comorbidities, single-agent chemotherapy may be better tolerated with acceptable results. Our increased knowledge of the molecular aspects of endometrial cancer biology has paved the way for clinical research to develop novel targeted antineoplastic agents (everolimus, temsirolimus, gefitinib, erlotinib, cetuximab, trastuzumab, bevacizumab, sorafenib) as more effective and less toxic options. Continued investigation into the molecular pathways of endometrial cancer development and progression will increase our knowledge of this disease leading to the discovery of novel, superior agents.

Abstract
OBJECTIVE To evaluate treatment outcomes and patterns of recurrence in patients with node-positive (International Federation of Obstetrics and Gynecology stage IIIC) adenocarcinoma of the uterus without serous or clear cell differentiation. METHODS The records of 71 women who were treated for stage IIIC endometrial adenocarcinoma at our institution between 1984 and 2005 were reviewed. All patients underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and lymphadenectomy. Fifty patients received definitive pelvic or extended-field radiotherapy with or without systemic therapy (regional RT group). Eighteen received adjuvant systemic platinum-based chemotherapy or hormonal therapy without external beam RT. The median follow-up for patients not dying of disease was 67 months. Survival rates were calculated using the Kaplan-Meier method; differences were assessed using log-rank tests. RESULTS Thirty-nine percent (28/71) of patients had involved paraaortic lymph nodes while 61% (43/71) had only pelvic lymph nodes. Five- and 10-year disease-specific survival (DSS) rates were 63% and 54%, respectively; corresponding overall survival rates were 60% and 47%. Grade was strongly associated with DSS (76% vs 46% at 5 years for low-grade vs high-grade tumors, P=0.004). Cervical or adnexal involvement was associated with decreased DSS, but lymph-vascular space invasion, age, race, body mass index, and number and location of positive nodes were not. Five-year pelvic-relapse-free survival (98% vs 61%, P=0.001), DSS (78% vs 39%, P=0.01), and overall survival (73% vs 40%, P=0.03) were significantly better for the regional RT group than the systemic therapy group. In patients treated without regional RT, the most common site of relapse was the pelvis. DSS was not significantly correlated with number of nodes removed in the regional RT group but was in patients treated without regional RT (P=0.001). CONCLUSIONS Patients treated without regional RT had a high rate of locoregional recurrence. Patients with stage IIIC endometrial adenocarcinoma who underwent surgical staging followed by external beam irradiation had a high rate of cure. Relapses in patients treated with EBRT primarily occurred in patients with grade 3 cancer who may be most likely to benefit from combined-chemoradiation treatment.

Abstract
Most patients with endometrial cancer (EMC) present their symptoms early in their course, leading to an overall favorable outcome. However, some patients who are in early-stage diseases may carry some risk features that would hamper their prognoses. For these early-stage diseases with high risk of recurrences, radiation therapy certainly plays a major role as an adjuvant treatment. Despite an excellent local diseases control by radiation, systemic failures are still encountered. To improve the prognoses, other types of adjuvant therapy have been attempted. In this review, various options of adjuvant treatment for this early-stage EMC including radiation therapy, chemotherapy, and hormonal therapy are discussed.

Abstract
The purpose of this article is to review the available literature for uterine papillary serous carcinoma (UPSC). A literature search was conducted to identify publications on UPSC. The literature on UPSC is composed mainly of retrospective, single-institution reports. Despite these limitations, several recommendations can be made. When UPSC is confirmed on preoperative biopsy, complete surgical staging should be performed. Although whole abdominal radiotherapy has a limited role in early-stage UPSC, there may be a role for postoperative chemotherapy in early-stage UPSC. In the setting of optimally debulked advanced-stage disease, a combination of radiation and chemotherapy may be indicated. In the setting of recurrent or suboptimally debulked advanced disease, a platinum-based regimen is recommended. Although comprising a minority of the women with endometrial cancer, women with UPSC do account for a disproportionate percentage of the recurrences. There is a need for clinical trials to determine the optimal therapy for this cohort of patients.

Abstract
Purpose To compare whole-abdominal irradiation (WAI) and doxorubicin-cisplatin (AP) chemotherapy in women with stage III or IV endometrial carcinoma having a maximum of 2 cm of postoperative residual disease. Patients and Methods Four hundred twenty-two patients were entered onto this trial. Of 396 assessable patients, 202 were randomly allocated to receive WAI, and 194 were allocated to receive AP. Irradiation dosage was 30 Gy in 20 fractions, with a 15-Gy boost. Chemotherapy consisted of doxorubicin 60 mg/m2 and cisplatin 50 mg/m2 every 3 weeks for seven cycles, followed by one cycle of cisplatin. Results Most patient and tumor characteristics were well balanced. The median patient age was 63 years; 50% had endometrioid tumors. Median follow-up time was 74 months. The hazard ratio for progression adjusted for stage was 0.71 favoring AP (95% CI, 0.55 to 0.91; P < .01). At 60 months, 50% of patients receiving AP were predicted to be alive and disease free when adjusting for stage compared with 38% of patients receiving WAI. The stage-adjusted death hazard ratio was 0.68 (95% CI, 0.52 to 0.89; P < .01) favoring AP. Moreover, at 60 months and adjusting for stage, 55% of AP patients were predicted to be alive compared with 42% of WAI patients. Greater acute toxicity was seen with AP. Treatment probably contributed to the deaths of eight patients (4%) on the AP arm and five patients (2%) on the WAI arm. Conclusion Chemotherapy with AP significantly improved progression-free and overall survival compared with WAI. Nevertheless, further advances in efficacy and reduction in toxicity are clearly needed.

Abstract
OBJECTIVE This study was performed to define the subgroups of patients who benefit from postoperative adjuvant chemotherapy in stage I and II endometrial carcinoma. METHODS A retrospective review of 170 International Federation of Gynecology and Obstetrics (FIGO) stage I and II endometrial carcinoma patients treated between 1988 and 2000 at Niigata University Hospital was performed. All patients underwent surgery, of which 41 patients underwent adjuvant chemotherapy, consisting of intravenous cisplatin, doxorubicin, and cyclophosphamide. Multivariate analysis was performed for the prognostic factors and actuarial techniques were used for the survival and recurrence rates. RESULTS The patients were divided into low-risk and high-risk groups based on the number of prognostic factors (tumor grade G3, outer half myometrial invasion, lymph-vascular space involvement (LVSI), and cervical invasion). The 5-year disease-free survival and the 5-year overall survival for the low-risk group were 97.4%, and 100%, respectively, which were significantly better than 77.4% and 88.1% for the high-risk group (P < 0.0001, P < 0.0001), respectively. Among high-risk group patients, the 5-year disease-free survival and the 5-year overall survival were 88.5% and 95.2% in 26 patients treated with adjuvant chemotherapy, and 50.0% and 62.5% in eight cases who underwent only surgery (P = 0.0150, P = 0.0226). Disease recurrence occurred in 7 (20.6%) of 34 high-risk group patients. Four of seven recurrences occurred in patients who did not receive postoperative chemotherapy, in which all four were distant failure. In the remaining three patients who were in the CAP group, two had vaginal wall recurrence and only one had pulmonary recurrence. Three recurrences were also observed in the 133 low-risk group patients. Only isolated vaginal wall recurrence occurred in three patients without adjuvant chemotherapy after the initial surgery. CONCLUSIONS There is possibility that postoperative adjuvant CAP may be omitted in surgical stage I or II endometrial cancer patients with 0 or 1 prognostic factor. The high-risk group of patients should be treated with postoperative adjuvant CAP to decrease distant failure and improve prognosis.

Abstract
PURPOSE Decreased expression of E-cadherin in endometrial cancer cells is associated with adverse prognostic features. This study aimed to evaluate the prognostic significance of decreased E-cadherin expression in patients with endometrial cancer. EXPERIMENTAL DESIGN Between 1992 and 1999, 102 endometrial cancer patients with stage I-III disease underwent primary surgery at the University of Chicago. Representative tissue specimens were immunostained with a monoclonal antibody to E-cadherin. A semiquantitative evaluation scale was developed based on the percentage of endometrial cancer cells with membranous E-cadherin staining. Tissue sections were scored as "3" if >75%, "2" if 25-75%, "1" if 5-25%, and "0" if <5% of cells stained. E-Cadherin staining was correlated with overall survival (OS), cause-specific survival (CSS), progression-free survival (PFS), and extrapelvic progression. Multivariate Cox proportional hazards modeling was used to estimate hazard ratios, controlling for clinicopathological characteristics and adjuvant treatment. Median follow-up for the study group was 58.5 months. RESULTS E-Cadherin staining was scored as 0, 1, 2, and 3 in 29.4%, 18.6%, 26.5%, 25.5% of cases, respectively. E-Cadherin expression was positively correlated with myometrial invasion (Kendall tau: 0.30, P < 0.01), and negatively correlated with grade (Kendall tau: -0.13, P = 0.15) and papillary serous or clear cell histology (Kendall tau: -0.14, P = 0.12). Five-year actuarial OS, CSS, PFS, and extrapelvic recurrence rates for negative (score = 0), heterogeneous (score = 1-2), and positive (score = 3) staining were as follows: OS, 69.2 versus 75.7 versus 81.0% (P = 0.64); CSS, 78.8 versus 91.2 versus 95.5% (P = 0.19); PFS, 69.1 versus 88.6 versus 92.2% (P = 0.079), and extrapelvic progression, 20.8 versus 7.3 versus 4.0% (P = 0.17). On multivariate Cox regression, a higher E-cadherin expression score was associated with decreased overall mortality [hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.34-1.03; P = 0.066), and statistically significant decreases in endometrial cancer mortality (HR, 0.23; 95% CI, 0.055-0.94; P = 0.040), disease progression (HR, 0.28; 95% CI, 0.10-0.77; P = 0.014), and extrapelvic recurrence (HR, 0.24; 95% CI, 0.062-0.97; P = 0.045). CONCLUSIONS Decreased E-cadherin expression is an independent prognostic factor for disease progression and mortality in pathological stage I-III endometrial cancer. Evaluation of E-cadherin expression may aid in the selection of patients for more aggressive adjuvant therapy.

Abstract
PURPOSE Patients with completely resected high-risk endometrial cancer have a risk of disease recurrence even with the addition of adjuvant pelvic radiotherapy (RT). A Phase II study was completed by the Radiation Therapy Oncology Group to assess the safety and toxicity of chemotherapy when combined with pelvic RT for these patients. METHODS AND MATERIALS Eligibility requirements included a total abdominal hysterectomy and bilateral salpingo-oophorectomy with Grade 2 or 3 endometrial adenocarcinoma with >50% myometrial invasion, stromal invasion of the cervix, or pelvic-confined extrauterine disease. This study was designed to administer 4500 cGy in 25 fractions to the pelvis, along with cisplatin (50 mg/m(2)) on Days 1 and 28. Vaginal brachytherapy with a low-dose-rate applicator (1 x 20 Gy to the surface) or high-dose-rate applicator (3 x 6 Gy to the surface) was performed after external beam RT. Four courses of cisplatin (50 mg/m(2)) and paclitaxel (175 mg/m(2)) were given at 4-week intervals after RT completion. RESULTS Forty-six patients were entered between October 1997 and April 1999. Two patients were ineligible (one with previous bladder cancer and one who had undergone surgery >8 weeks before the start of RT). Follow-up ranged from 6.9 to 48.8 months (median, 28.7 months). The disease was Stage III, II, and I in 66%, 16%, and 18% of patients, respectively. Two patients were not assessable because of incomplete treatment data. The protocol completion rate was 98% (41 of 42 assessable patients). Acute toxicity during RT/chemotherapy was Grade 1 in 27%, Grade 2 in 43%, Grade 3 in 27%, and Grade 4 in 2%. During adjuvant chemotherapy, the toxicity was Grade 1 in 7%, Grade 2 in 7%, Grade 3 in 21%, and Grade 4 in 62%. Severe toxicity was primarily hematologic. Chronic toxicity was Grade 1 in 20%, Grade 2 in 39%, Grade 3 in 16%, and Grade 4 in 2%, including 1 patient with a Grade 4 small bowel complication. At 24 months, the pelvic recurrence, regional recurrence, distant recurrence, disease-free survival, and overall survival rate was 2%, 3%, 17%, 83%, and 90%, respectively. CONCLUSION This treatment protocol demonstrated an excellent treatment completion rate and expected toxicity. Longer follow-up is needed to assess the outcome. To assess the efficacy of this adjuvant treatment program, a Phase III trial (Radiation Therapy Oncology Group 9905) was designed with high-risk uterine-confined disease to be randomized between pelvic RT alone and pelvic RT with chemotherapy.

Abstract
OBJECTIVES New and much debated data of the endometrial cancer concerning the preoperative assessment of myometrial invasion, the surgical staging, and the adjuvant treatment. PATIENTS AND METHODS Medline (1998-2002): searching for "endometrial carcinoma". RESULTS The pap smears are useful when it is difficult to have a transvaginal ultrasonography or an MRI. We can perform the pap smears and the endometrial biopsy in the clinic. If a patient has pap smears with malignant cells or elevated preoperative CA 125, it probably is a cancer with poor prognostic factors. Surgical staging with abdominal and node evaluation is necessary. The MRI seems to be the best preoperative imaging because we have information about adnexal and abdominal metastases, pelvic or aortic nodes and the invasion of the myometrium. So it gives us information on the surgical route, and provides indication for a lymphadenectomy. The surgical staging is a part of the treatment of the endometrial cancer: an exploration of the peritoneal cavity, a pelvic lymphadenectomy, a para-aortic lymphadenectomy if the pelvic nodes are positive or if there are factors of bad prognosis (deep stage IC, grade 3, adnexal or abdominal involvement, serous carcinoma of the endometrium). It can be performed if technical conditions are correct. The adjuvant teletherapy in the documented stage IpN0 (surgical staging with pelvic lymphadenectomy) does not seem to be necessary. But we can perform an adjuvant brachytherapy (high-dose rate if it is possible) in patients with a high local recurrence (stage IC, stage I with grade 3, stage IB grade 2). CONCLUSION The preoperative MRI is useful choosing the surgical approach, and the depth of the myometrial invasion, which can be an indication for a pelvic lymphadenectomy. The surgical staging must be a part of the treatment of the endometrial cancer. So the adjuvant teletherapy in patients with stage IpN0 documented should not be used.

Abstract
PURPOSE The aim of the study was to evaluate the 10-year treatment outcome of utilizing adjuvant high-dose whole abdominal irradiation (WAPI technique) with a pelvic/vaginal boost in patients with stage I-III endometrial carcinoma at high risk for intra-abdominopelvic recurrence, including serous-papillary and clear cell histologies. MATERIAL AND METHODS In a prospective nonrandomized trial, 132 patients were treated with adjuvant WAPI between November 1981 and October 2001. Forty-three patients (32%) were 1998 FIGO stage I-II and 89 (68%) were stage III. Pathological features included the following: 66 (52%) with deep myometrial invasion, 50 (38%) with positive peritoneal cytology, 89 (67%) with high-grade lesions, 25 (19%) with positive pelvic/para-aortic lymph nodes, and 58 (45%) with serous-papillary or clear cell histology. RESULTS The mean follow up was 6.4 years (range 0.6-16.1). For the entire group, the 5- and 10-year cause-specific survival (CSS) was 77 and 72%, whereas the disease-free survival (DFS) was 55 and 45%. When stratified by histology the 5- and 10-year CSS for adenocarcinoma was 75 and 70%, while serous-papillary/clear cell was 80 and 74% (P = 0.314). The 5- and 10-year DFS for adenocarcinoma was 59 and 49%, whereas serous-papillary/clear cell was 49 and 38% (P = 0.563). For surgical stages I-II, the 5-year CSS was 83% for adenocarcinoma and 89% for serous-papillary (P = 0.353). For stage III, it was 73 and 62% (P = 0.318), respectively. Forty-six patients (35%) relapsed. The first site of failure was the abdomen/pelvis in 27/46 (59%). When stratified by histologic variant, 34% of patients with adenocarcinoma and 41% with serous-papillary developed recurrent disease. In multivariate regression analysis only advancing age was of prognostic significance for CSS (P = 0.025) and DFS (P = 0.026). Chronic grade 3/4 GI toxicity was seen in 14%, and 2% of patients developed grade 3 renal toxicity. CONCLUSION High-dose adjuvant WAPI is very effective treatment with excellent 10-year results for stage I-III endometrial carcinoma with risk factors for intra-abdominopelvic recurrence, including serous-papillary or clear cell histology. The low long-term complication rate with high CSS makes high-dose WAPI the treatment of choice for these patients with significant comorbidities.

Abstract
Surgical staging has changed the method by which patients with endometrial cancer are managed. Before the routine use of lymph node dissection, patients were presumed to have nodal disease based on imaging studies, palpation, and biopsy. The move to a surgically based staging system in 1988 created a new subgroup of patients who had documented nodal disease. The risk of nodal involvement is related primarily to tumor grade and depth of myometrial invasion. Although patients with nodal disease are uncommon, treatment of these patients poses multiple challenges. It is our belief that unless nodes are surgically assessed, the clinician will not know whether the nodes are involved. A thorough lymphadenectomy with removal of nodal tissue from multiple pelvic sites and from bilateral para-aortic regions is recommended for most patients with endometrial cancer. Identification of positive nodes allows appropriate postoperative therapies to be used, and data support that nodal dissection may be therapeutic and prognostic. Patients with positive nodes should receive radiation therapy directed to the nodal distribution, with patients having involved para-aortic nodes receiving an extended field. Whole abdominal radiation has been used, especially in patients with adnexal disease or positive cytology. The role of whole abdominal radiation remains in question. The most promising treatment option is combination therapy with sequential radiation and chemotherapy. Active chemotherapy agents in endometrial cancer are doxorubicin, cisplatin, and paclitaxel.

Abstract
PURPOSE To evaluate the long-term results of treatment using adjuvant whole abdominal irradiation (WAPI) with a pelvic/vaginal boost in patients with Stage I-III endometrial carcinoma at high risk of intra-abdominopelvic recurrence, including clear cell (CC) and serous-papillary (SP) histologic features. METHODS AND MATERIALS In a prospective nonrandomized trial, 119 patients were treated with adjuvant WAPI between November 1981 and April 2000. All patients were analyzed, including those who did not complete therapy. The mean age at diagnosis was 66 years (range 39-88). Thirty-eight patients (32%) had 1989 FIGO Stage I-II disease and 81 (68%) had Stage III. The pathologic features included the following: 64 (54%) with deep myometrial invasion, 48 (40%) with positive peritoneal cytologic findings, 69 (58%) with high-grade lesions, 21 (18%) with positive pelvic/para-aortic lymph nodes, and 44 (37%) with SP or CC histologic findings. RESULTS The mean follow-up was 5.8 years (range 0.2-14.7). For the entire group, the 5- and 10-year cause-specific survival (CSS) rate was 75% and 69% and the disease-free survival (DFS) rate was 58% and 48%, respectively. When stratified by histologic features, the 5- and 10-year CSS rate for adenocarcinoma was 76% and 71%, and for serous papillary/CC subtypes, it was 74% and 63%, respectively (p = 0.917). The 5- and 10-year DFS rate for adenocarcinoma was 60% and 50% and was 54% and 37% serous papillary/CC subtypes, respectively (p = 0.498). For surgical Stage I-II, the 5-year CSS rate was 82% for adenocarcinoma and 87% for SP/CC features (p = 0.480). For Stage III, it was 75% and 57%, respectively (p = 0.129). Thirty-seven patients had a relapse, with the first site of failure the abdomen/pelvis in 14 (38%), lung in 8 (22%), extraabdominal lymph nodes in 7 (19%), vagina in 6 (16%), and other in 2 (5%). When stratified by histologic variant, 32% of patients with adenocarcinoma and 30% with the SP/CC subtype developed recurrent disease. Most failures for either histologic group occurred within the abdominopelvic region. However, one-third of the adenocarcinoma recurrences were in the lung. Multivariate regression analysis (age, surgical stage, grade, myometrial invasion, histologic type, lymph node status, and peritoneal cytology) demonstrated age (p = 0.019) and surgical stage (p = 0.036) to be of prognostic significance for CSS; age (p = 0.036) was the only significant prognostic factor for DFS. Grade 1-2 gastrointestinal and hematologic acute toxicities were common. Asymptomatic bibasilar scarring on chest X-ray and mild elevation of liver enzymes were seen in almost 50% of the patients. Even though chronic toxicities were less frequent, 12% developed Grade 3-4 gastrointestinal and 2% Grade 3 renal toxicities. CONCLUSION Adjuvant WAPI is very effective treatment with excellent 10-year results for Stage I-III endometrial carcinoma with risk factors for intra-abdominopelvic recurrence, including SP or CC histologic variants, deep myometrial invasion, high grade, nodal involvement, and positive peritoneal cytology. The low long-term complication rate with high CSS rate makes WAPI the treatment of choice for these patients with significant comorbidities.

Abstract
OBJECTIVE We have assessed prognostic factors and the efficacy of adjuvant chemotherapy in stage I uterine endometrial carcinoma. METHODS 251 primary surgically treated stage I patients were studied. Prognostic factors were evaluated and 5-year and 10-year survival rates were compared in patients with lymph-vascular space invasion to investigate whether adjuvant chemotherapy improves survival. RESULTS The overall 5-year and 10-year survival rates were 94% and 93%. Multivariate analysis indicates that lymph-vascular space invasion is the most significant prognostic factor in both 5- and 10-year survival rates (P<0.001 at both times) and stage/depth of invasion is significant for the 10-year survival rate (P=0.04). Of 54 patients with lymph-vascular space invasion, statistically significant differences were observed in 10-year survival rate (P=0.02) between patients who had surgery followed by adjuvant chemotherapy (n=23) and patients who had surgery alone (n=31). Toxicities were mild to moderate (30%). CONCLUSIONS The clinical importance of lymph-vascular space invasion and the efficacy of adjuvant chemotherapy were confirmed. This observation warrants a larger comparative study with adjuvant chemotherapy.

Abstract
OBJECTIVE The purpose of this article is to present a summary of the pharmacology of anthracyclines as well as to review the results of clinical trials including patients with gynecologic malignancies treated with anthracycline-based therapy. METHODS We performed a MEDLINE literature search of relevant clinical trials for the scope of this review that evaluated anthracycline-based therapy in gynecologic malignancies. RESULTS Doxorubicin has established activity in carcinomas that arise in the ovary, uterine cervix, and endometrium as well as in uterine sarcomas. However, doxorubicin has structural characteristics that limit its efficacy and safety. Newer anthracyclines with distinct structure, pharmacokinetics, pharmacodynamics, and toxicity profiles have been developed to overcome the limitations of doxorubicin and to further exploit the activity of anthracyclines. Epirubicin is characterized by a structural formula that confers similar cytotoxic antitumor activity with fewer associated side effects than its analogue. Most recently, pegylated liposomal formulations, with distinct pharmacokinetic properties and a favorable toxicity profile, have shown antitumor activity as salvage therapy in ovarian cancer. Intraperitoneal mitoxantrone is also associated with activity in ovarian cancer; however, its clinical use is limited by the severity of local adverse effects. CONCLUSIONS The role of anthracyclines in the management of advanced gynecologic malignancies is important as part of first-line therapy or as a salvage approach. Newer anthracycline agents such as epirubicin and pegylated liposomal doxorubicin are associated with a more favorable toxicity profile. Clinical trials are under way to further explore the role of newer anthracycline-based regimens as first-line or salvage treatment in gynecologic malignancies.

Abstract
Endometrial cancer is the most common gynecologic malignancy in the United States. The mean and median age of women with endometrial adenocarcinoma is 61 years. Most endometrial cancers are type I estrogen-dependent endometrioid adenocarcinomas. Most women with endometrial adenocarcinoma have stage I disease. Patients with stage I disease endometrial adenocarcinoma can be treated with a simple hysterectomy, bilateral salpingo-oophorectomy, peritoneal lavage, and periaortic node dissection in selected cases. The probability of survival according to international statistics is as follows: stage IA, 91%; stage IB, 88%; stage IC, 81%; stage IIA, 77%; stage IIB, 67%; stage IIA, 60%; stage IIIB, 41%; stage IIC, 32%; stage IVA, 20%; stage IVB, 5%.

Abstract
OBJECTIVE This study was performed to assess the prognostic factors and patterns of recurrence in stage III endometrial carcinoma treated with surgery and adjuvant chemotherapy. METHODS A retrospective review of 61 stage III endometrial carcinoma patients treated between 1988 and 1998 at Niigata University Hospital was performed. All patients underwent surgery, followed by adjuvant chemotherapy consisting of intravenous cisplatin, doxorubicin, and cyclophosphamide. Multivariate analysis was performed for the prognostic factors and actuarial techniques were used for the survival and recurrence rates. RESULTS The 5-year disease-free survival was 78.6%. Multivariate analysis revealed deep myometrial invasion and lymph-vascular space involvement correlated significantly with disease-free survival. Based on these two factors, the patients could be divided into low-risk and high-risk groups. The 5-year disease-free survival for the low-risk group was 100%, which was significantly better than the 59.1% for the high-risk group. Disease recurrence occurred in 13 of 30 high-risk patients, and there was no recurrence in the 31 low-risk patients. Looking at the patterns of recurrence for the high-risk group by lymph node metastasis, 5 recurrences were locoregional, 1 was locoregional/distant, and 1 was distant in 16 node-positive high-risk patients. In 14 node-negative patients, 5 had distant and 1 had locoregional/distant recurrences. CONCLUSIONS The locoregional failure in the node-positive high-risk group deserves further attention. For improvement of locoregional control, it may be worthwhile to consider new strategies. The role of new adjuvant chemotherapy should be investigated to control distant failure in node-negative high-risk patients.

Abstract
SUBJECT Management of patients with gynecologic cancer can now often be tailored to the extent of the disease and preservation of child-bearing ability and/or sexual function may be possible for certain women with early invasive disease. METHOD A better understanding of the tumor-biology, and the consideration of different clinicopathologic factors, that bear prognostic significance in therapeutic modalities, will allow more and more individualization of treatment. DISCUSSION Management of young women with early gynecologic cancer should therefore be individualized with the risk of conservative therapy balanced against the dangers and advantages of more radical therapy. Experts in gynecologic oncology and infertility together with an informed patient and her family should make treatment decisions. OUTCOME This article will review the conservative surgical management of early invasive cancers of the ovary, cervix and endometrium, in order to help preserve child-bearing capacity. In addition, management of gynecologic cancers diagnosed during pregnancy will also be discussed.

Abstract
OBJECTIVE To evaluate the risk of pelvic recurrence (PVR) in high-risk pathologic Stage I--IV endometrial carcinoma patients after adjuvant chemotherapy alone. METHODS Between 1992 and 1998, 43 high-risk endometrial cancer patients received adjuvant chemotherapy. All patients underwent primary surgery consisting of total abdominal hysterectomy and bilateral salpingo-oophorectomy. No patients received preoperative radiation therapy (RT). Regional lymph nodes and peritoneal cytology were sampled in 62.8% and 83.7% of cases, respectively. Most patients had Stage III--IV disease (83.7%) or unfavorable histology tumors (74.4%). None had evidence of extra-abdominal disease. All patients received 4-6 cycles of chemotherapy as the sole adjuvant therapy, consisting primarily of cisplatin and doxorubicin. Recurrent disease sites were divided into pelvic (vaginal, nonvaginal) and extrapelvic (para-aortic, upper abdomen, liver, and extra-abdominal). Median follow-up was 27 months (range, 2--96 months). RESULTS Twenty-nine women (67.4%) relapsed. Seventeen (39.5%) recurred in the pelvis and 23 (55.5%) in extrapelvic sites. The 3-year actuarial PVR rate was 46.5%. The most significant factors correlated with PVR were cervical involvement (CI) (p = 0.01) and adnexal (p = 0.05) involvement. Of the 17 women who developed a PVR, 8 relapsed in the vagina, 3 in the nonvaginal pelvis, and 6 in both. The 3-year vaginal and nonvaginal PVR rates were 37.8% and 26%, respectively. The most significant factor correlated with vaginal PVR was CI (p = 0.0007). Deep myometrial invasion (p = 0.02) and lymph nodal involvement (p = 0.03) were both correlated with nonvaginal PVR. Nine of the 29 relapsed patients (31%) developed PVR as their only (6) or first site (3) of recurrence. Factors associated with a higher rate of PVR (as the first or only site) were CI and Stage I--II disease. CONCLUSIONS PVR is common in high-risk pathologic Stage I-IV endometrial cancer patients after adjuvant chemotherapy alone. These results support the continued use of locoregional RT in patients undergoing adjuvant chemotherapy. Further studies are needed to test the addition of chemotherapy to locoregional RT.

Abstract
Cytotoxic chemotherapy has an established role in the treatment of many solid tumours that are considered to be incurable with any modern treatment method. Such treatment may result in an improvement in quality of life without influencing overall survival. In this chapter the evidence to support the use of chemotherapy in patients with advanced or recurrent endometrial adenocarcinoma is reviewed. The most effective single agent and combination treatments are outlined. Although evidence from randomized trials is limited, combination chemotherapy can lead to response rates of over 40% in patients with advanced disease. The role of chemotherapy as adjuvant treatment in patients with early-stage disease is less well defined and this treatment is not recommended outside a clinical trial. The role of chemotherapy for treatment of the aggressive histological variant, uterine papillary serous carcinoma is also discussed.

Abstract
OBJECTIVE Postoperative radiotherapy (RT) is the most used adjuvant treatment in high risk endometrial cancer (HREC), and it appears to reduce the incidence of pelvic relapses but doesn't seem to improve survival. Paclitaxel (P) has shown in vitro and clinical activity against endometrial cancer, and it is also a potent radiosensitizer by blocking dividing cells in G2/M phase. This is the first study that verifies the feasibility of a treatment with concomitant weekly chemotherapy and RT to potentially reduce the incidence of local and distant relapses in order to improve survival in HREC. PATIENTS AND METHODS Thirteen patients with HREC have entered the feasibility study at San Raphael Hospital University of Milan. All patients underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and surgical staging. Four patients presented stage IC disease, 2 women had IIB stage tumors, 5 patients revealed IIIA stage disease, and 2 had stage IIIC. The patients received P (60 mg./m(2)) via a continuous 1-h infusion once weekly during the 5 weeks of RT (mean radiation dose of 50.4 Gy). At the end of RT three additional consolidation courses of P (80 mg/m(2)) were subministered. Eleven patients received only pelvic irradiation; in 2 cases radiotherapy was performed on an extended field. RESULTS Eleven of the 13 enrolled patients have completed the radiochemotherapy regimen. A total of 100 courses of P were performed. All patients completed the RT. Adverse effects were evaluated. Hematological toxicity was mild: four cycles (4%) were delayed 1 week because of grade 1 neutropenia. No severe thrombocytopenia was identified. No hemotrasfusions were performed. One cycle was delayed for fever. Gastrointestinal adverse effects were observed in 2 patients, in which the cycles were delayed 1 week because of diarrhea. One cycle was delayed 1 week because of dermatitis. One patient developed a subocclusion 8 weeks after the end of the treatment, with medical resolution. No patients developed hypersensitivity reactions. CONCLUSIONS Concomitant P and RT is safe and acceptable treatment in patients with HREC. Prospective clinical studies are necessary to evaluate the benefits of this regimen for the long-term survival rate.

Abstract
Although endometrial cancer is the most common female malignancy, evidence-based uniform guidelines for postoperative therapy have not been established. The most logical management is adjuvant irradiation tailored to the extent of surgery, the tumour grade, depth of myometrial invasion, degree of lymph node involvement and age of the patient. Currently, the only widely accepted treatment recommendations are no further therapy in low-risk patients who underwent extensive surgical staging, and external beam radiotherapy (EBRT) in high-risk patients. Most authors recommend postoperative application of only one radiotherapy modality: either brachytherapy (BRT) or EBRT, as their routine combination does not clearly improve the outcome but does increase the risk of late complications. A combination of BRT and EBRT should however be considered in patients with stage II disease, for infiltration of the lower uterine segment, vaginal involvement, positive or close surgical margins, capillary space involvement or unfavourable histology. Two recent randomized studies including mostly intermediate-risk patients managed with either extensive surgical staging or total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH&BSO) with or without postoperative EBRT, showed better local control but no survival benefit from adjuvant irradiation. Two ongoing Gynecologic Oncology Group (GOG) studies compare adjuvant chemotherapy with pelvic or abdominal irradiation in patients with high risk of local relapse. The role of adjuvant radiotherapy (EBRT with or without BRT) in high-risk patients as well as the value of lymphadenectomy in patients fit for such surgery is being addressed in a trial co-ordinated by the Medical Research Council. Future studies are warranted to define whether any irradiation should be employed in intermediate-risk patients and which radiotherapy modality should be used in high-risk node-negative patients with stage I tumours (stage Ib grade 3 and all stage Ic). Other issues which should be addressed in future studies include the extent of surgery, the role of systemic therapies, the relevance of novel biologic prognostic factors, salvage therapies after recurrence, cost-benefit analysis and quality of life.

Abstract
The median survival of women with advanced or recurrent endometrial cancer is less than one year. Of the women with early stage endometrial cancer and poor prognostic factors like high grade or deep myometrial invasion, 40% will recur. Over the last decade, incredible strides have been taken in evaluating systemic therapy for this disease, however, survival rates remain poor. Progestin therapy offers a 10 - 20% response rate and survival of less than one year. Progestins are most effective in women with well-differentiated tumours and long disease-free interval. There is no role for adjuvant progestin therapy in early stage disease. Single-agent chemotherapy with most activity include ifosfamide, cisplatin/carboplatin, doxorubicin and paclitaxel. Combination chemotherapy provides a response rate of 40 - 60%, however, median survival is still less than a year. New areas of research include the identification and evaluation of new active endocrine therapies (i.e., LY-353381.HCl and letrozole), chemotherapeutics (i.e., paclitaxel), evaluating chemotherapeutic agents in combination (i.e., paclitaxel, doxorubicin and platinum), in addition to radiation or instead of radiation. New avenues under development involve the specific molecules and pathways responsible for the initiation and growth of endometrial carcinoma (i.e., Herceptintrade mark). Exciting developments in the understanding of the molecules involved in tumour development and metastasis will allow the development of specific and selective inhibitors.

Abstract
To determine the outcome of patients with endometrial endometrioid adenocarcinoma following adjuvant chemotherapy, CAP (cyclophosphamide, pirarubicin and cisplatin) and EP (etoposide and cisplatin) were assigned at random to patients with Ic or more advanced stage carcinoma, and their efficacy was compared. These patients were treated by the Tokai Endometrial Cancer Study Group (Nagoya University and related institutions) between January 1992 and June 1996. The 5-year survival rate was 88.4% in the CAP group and 95.1% in the EP group; the difference between the two groups was not significant (p = 0.3496). The disease-free survival rate was 80. 3% in the CAP group and 84.8% in the EP group (nonsignificant: p = 0. 4533). However, the 5-year disease-free survival rates were 95.1 and 71.0% in patients with preoperative CA125 levels <35 and > or =35 IU/ml, and there was a significant difference in disease-free survival curves (p<0.05). A significant difference was also observed in disease-free survival curves between patients with and without pelvic lymph node metastasis (5- year disease-free survival rate: 68.8 and 88.2% in patients with and without pelvic lymph node metastasis, respectively, p<0.05). Multivariate analysis of disease- free survival showed that the preoperative CA125 level, and pelvic lymph node metastasis were significant risk factors for recurrence. In conclusion, the EP chemotherapy had no significant advantage in terms of survival and disease-free survival compared to CAP, although these rates were superior in the EP group compared to the CAP group.

Abstract
PURPOSE To evaluate the treatment outcomes in patients with optimally debulked Stage III and IV endometrial adenocarcinoma (ACA) or Stages I-IV uterine papillary serous (UPSC) or clear cell (CCC) carcinoma of the uterus, treated postoperatively with whole abdominopelvic irradiation (WAPI). METHODS AND MATERIALS Between 1979 and 1998, 48 patients received postoperative WAPI at our institution. Twenty-two patients had FIGO Stage III or Stage IV ACA and 26 patients had FIGO Stages I-IV UPSC or CCC. The median dose was 30 Gy to the upper abdomen and 49.8 Gy to the pelvis. Mean follow-up was 37 months (2.4-135 months). RESULTS The 3-year estimated disease-free survival (DFS) and overall survival (OS) rates for the entire group were 60% and 77%, respectively. Patients with ACA had 3-year DFS and OS of 79% and 89%, respectively, compared with 47% and 68% in the UPSC/CCC group. Early-stage patients (I and II) with UPSC/CCC had 3-year DFS and OS of 87% compared with 32% and 61% in those with advanced (Stage III and IV) disease. The 3-year actuarial major complication rate was 7%, with no treatment-related deaths. All 4 failures in the ACA group were extra-abdominal and 6 of the 11 in the UPSC/CCC group had an extra-abdominal component. Age and UPSC/CCC histology were significant prognostic factors for DFS and OS. In addition, stage and number of extrauterine sites of disease were significant predictors for DFS in UPSC/CCC. CONCLUSION WAPI is a safe, effective treatment for patients with optimally debulked advanced-stage uterine ACA or early-stage UPSC/CCC. Survival was significantly worse in advanced-stage UPSC/CCC patients. We recommend future trials of WAPI with concurrent, or subsequent systemic therapy in patients with advanced-stage UPSC or CCC.

Abstract
We have evaluated the growth inhibitory effects of paclitaxel alone or irinotecan (CPT-11) alone and their combined effects with other drugs on human endometrial cancer cell lines. IC50 doses of paclitaxel (Tx), SN-38 (active metabolite of CPT-11; 7-ethyl-10-hydroxycamptothecin) and cisplatin, including other drugs which have been used for treatment of patients with endometrial cancer, were examined using five human endometrial cancer cell lines (Ishikawa, HEC-1A, HEC-50B, HEC-59 and HEC-108). When in vitro sensitivity was defined IC50 lower than 10% of the peak plasma concentration (PPC), all endometrial cancer cell lines were sensitive to paclitaxel and three of five endometrial cancer cell lines were sensitive to SN-38, whereas cisplatin was not active against any endometrial cancer cell lines used in this study. Regarding the other drugs, aclarubicin (ACR) and actinomycin D (ACD) were active against four of five endometrial cancer cell lines, etoposide (VP-16) and pirarubicin (THP) against two, and 5-fluorouracil (5-FU) against only one, while ifosfamide (4-OHIFO) was not active against any endometrial cancer cell lines. When combined effects of paclitaxel or SN-38 with other one drug were determined by the median-effect analysis, paclitaxel followed by cisplatin resulted in synergistic effects to all endometrial cancer cell lines. Paclitaxel followed by SN-38 also had synergistic effects to four cell lines. Sequential but not simultaneous administration of taxol and THP-adriamycin showed synergistic effects to three cell lines. In combinations of SN-38 with other drugs, simultaneous administration of SN-38 and cisplatin resulted in synergistic effects to all cell lines. It is noteworthy that ACD followed by SN-38 showed synergistic effects to all cell lines, and simultaneous treatment of ACD and SN-38 or SN-38 followed by ACD also resulted in synergistic effects to three cell lines. THP-adriamycin followed by SN-38 had synergistic effects to four cell lines. The present quantitative data analysis for synergism provides a basis for a rational design of clinical protocols for combination chemotherapy in patients with endometrial cancer of the uterus.

Abstract
Identification of histopathologic factors that predict the risk of tumor recurrence allows for selection of women with endometrial cancer who might benefit from adjuvant therapy. Most studies of adjuvant treatment have focused on external-beam irradiation or oral progestational agents and have failed to document a survival advantage for treated patients. Although recurrent or metastatic endometrial tumors often respond to salvage treatment with cytotoxic agents, there is relatively little experience with postoperative systemic chemotherapy used in an adjuvant setting. A few nonrandomized trials-using doxorubicin/platinum-based regimens-have suggested that adjuvant chemotherapy may be beneficial in some patient subsets. Data from larger-scale, randomized trials do not exist. Additional clinical experience is needed before a definite role for adjuvant chemotherapy can be established.

Abstract
Kasamatsu T, Shiromizu K, Takahashi M, Matsumoto K, Shirai T. Analysis of initial failure site and spread pattern in endometrial carcinoma: a Japanese experience. This retrospective study was undertaken in an attempt to identify initial failure sites and spread patterns in patients with endometrial carcinoma in Japan. A retrospective clinicopathologic review of 272 patients treated from 1983 to 1994 at Saitama Cancer Center was performed. Patients underwent total hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Postoperative external radiation was given to the patients with deep myometrial invasion, high grade tumor, and/or lymph node metastasis. Following surgery, chemotherapy was given to the patients with extrapelvic metastasis. Of the 272 patients, 262 had no residual disease after initial treatment and 10 had confirmed residual disease. Of the 262 patients, 32 (12.2%) suffered recurrence. The recurrence rates for stage I, II, III, and IV were 5.6% (10/178), 5.7% (2/35), 35.3% (18/51), and 100% (2/2), respectively. Of the 32 patients who failed, 6 (18.8%) experienced local failure, 13 (40.6%) had distant failure without peritoneal spread, and 13 (40.6%) had distant failure with peritoneal spread. In distant failure, the incidence of peritoneal spread was highest (50.0%, 13/26), closely followed by that of pulmonary metastasis (46.2%, 12/26). Furthermore, of those patients with residual disease, peritoneal spread was found in 80% (8 of 10). Five of the six patients (83.3%) with local failure survive, but all patients with peritoneal spread have died. Peritoneal dissemination is an important failure pattern and should be considered a top priority in an attempt to improve survival in patients with endometrial carcinoma.

Abstract
UNLABELLED Currently, available chemotherapy regimens for patients with advanced or recurrent endometrial cancer are generally not curative. Thus, there is a need to identify more active single agents in this disease. In this study patients pre-treated and not pre-treated with first line combination chemotherapy were entered into a randomized phase II study of either cyclophosphamide (CYCLO) or Ifosfamide (IFOS). PATIENTS AND METHOD Sixty one eligible patients with recurrent or metastatic histologically proven, adenocarcinoma of the uterine corpus entered the study. The median age at entry was 62 (range 40-74) years. Twenty patients (33%) had prior hormonal treatment and 31 (51%) prior chemotherapy. CYCLO was given at a dose of 1200 mg/m2 and IFOS at a dose of 5 g/m2. Both drugs were administered i.v. over 24 hours on day one every three weeks. Adequate pre- and post hydration as well as use of Mesna in the Ifosfamide arm were mandatory. RESULTS A median of two treatment cycles (range 1-12) per patient were given. In the chemotherapy-naive patients, in the CYCLO arm two PRs (RR 14%, C.I. 2-43%) were seen and in the IFOS arm two CRs, two PRs, (RR 25%, C.I. 7-52%) were observed. No responses were seen in pre-treated patients. The duration of responses were: 15+, 7+ months for the CRs, 15+ and 5 months for PRs in IFOS arm and 67+, 4 months in CYCLO arm. The hematological toxicity was dose-limiting and similar in both treatment arms. No serious non hematological toxicities were reported, but a transient increase of the creatinine blood level was seen in two IFOS patients (6%). CONCLUSION Ifosfamide is an active drug in the treatment of chemotherapy-naive patients with advanced endometrial cancer and its application in currently used (combination) regimens should be considered.

Abstract
The current status and future directions of chemotherapy in the management of endometrial cancer are reviewed. For patients with advanced or recurrent endometrial carcinoma the most active single drugs are doxorubicin, epirubicin, cisplatin, carboplatin, paclitaxel, ifosfamide, 5-fluorouracil and vincristine with response rates ranging from 18 to 36%. Data at the present time support the conclusion that if chemotherapy is indicated a combination of doxorubicin + cisplatin is the standard chemotherapy for patients with advanced or recurrent endometrial carcinoma and yields a response rate of 47-60%. A first trial using a combination of these drugs with paclitaxel promises an increase in response rate to 73%, but data regarding prolongation of survival are not yet available. Up to now the benefit of neither chemotherapy nor endocrine therapy could be established in the adjuvant setting.

METHODS We examined tumor specimens obtained from 46 patients with endometrial cancer (9 FIGO stage IA, 16 stage IB, 8 stage IC, 1 stage IIA, 6 stage IIB, and 6 stage IIIC). The cellular expression of TP and the intratumoral density of microvessels were determined by immunohistochemistry using monoclonal antibodies to TP and factor VIII-related antigen, respectively. We investigated the relationship between the cellular expression of TP and the following factors: clinicopathologic features (menopausal status, histologic type, tumor size, histologic grade, myometrial invasion, cervical invasion, and metastasis), the microvessel count, and the disease-free survival period. RESULTS Of the 46 tumors, 19 (41%) were TP-positive. The microvessel count was significantly higher in TP-positive tumors than in TP-negative tumors (P = 0.01, Mann-Whitney U test). There was no significant correlation between TP expression and clinicopathologic features, and there was no significant difference in the disease-free survival period between patients with TP-positive tumors and patients with TP-negative tumors. CONCLUSION TP expression was not correlated with clinicopathologic features or prognosis, but was associated with an increased density of microvessels in endometrial cancer. These findings suggest that TP may play an important role in angiogenesis and may be involved in the tumorigenesis of endometrial cancer.

Abstract
Carcinoma of the uterine corpus (endometrial cancer) remains the gynecologic malignant disease with the highest annual prevalence in the United States. The most common histologic type is adenocarcinoma, although more aggressive variants (e.g., papillary serous carcinoma and clear cell carcinoma) have been identified. Risk factors that are strongly associated with the development of endometrial cancer include tamoxifen therapy, obesity, and stimulation from unopposed estrogen (from exogenous sources or endogenously secreting ovarian tumors). The current staging system of the International Federation of Gynecology and Obstetrics is based on surgical-pathologic findings. Survival has been directly correlated with tumor stage in this staging system. The cornerstone of therapy is total abdominal hysterectomy with bilateral salpingo-oophorectomy. Pelvic and para-aortic lymphadenectomy may provide additional prognostic information but probably does not confer a therapeutic advantage. Moreover, such nodal dissections predispose to the development of complications, especially in women who subsequently receive pelvic irradiation. Other than surgical treatment, irradiation is the single most active therapy for endometrial carcinoma. In fact, some women who are not candidates for hysterectomy because of medical contra-indications can be cured with radiation alone. Adjuvant therapy following hysterectomy is based on patient- and tumor-related features that provided prognostic information for incidence and pattern of recurrence. Adjuvant treatment usually includes pelvic irradiation for selected patients. Current investigational strategies are directed at the role of whole-abdomen irradiation, extended-field irradiation, and systemic chemotherapy. The most active systemic agents include cisplatin, doxorubicin, paclitaxel, and progestins.
