Objective: The aim of the study was to assess interaction of lymph node dissection (LND), adjuvant chemotherapy (CT), and radiotherapy (RT) in stage I uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCC)., Methods/materials: The National Cancer Data Base was queried for women diagnosed with International Federation of Gynecology and Obstetrics stage I UPSC and UCC from 1998 to 2012. Overall survival (OS) was estimated for combinations of RT and CT by the Kaplan-Meier method stratified by histology and LND. Multivariate Cox proportional hazard models were generated., Results: Uterine papillary serous carcinoma: 5432 women with UPSC were identified. Uterine papillary serous carcinoma had the highest 5-year OS with CT + RT with (83%) or without LND (76%). On multivariate analyses, CT [hazard ratio (HR), 0.77; P = 0.01] and vaginal cuff brachytherapy (HR, 0.68; P = 0.003) with LND were independently associated with OS. Without LND, vaginal cuff brachytherapy (HR, 0.53; P = 0.03), but not CT (HR, 1.21; P = 0.92), was associated with OS. Uterine clear cell carcinoma: 2516 women with UCC were identified. Uterine clear cell carcinoma with and without LND had comparable 5-year OS for all combinations of CT and RT on univariate and multivariate analyses., Conclusions: In stage I papillary serous uterine cancer, brachytherapy and CT were associated with increased survival; however, the benefit of chemotherapy was limited to those with surgical staging. In contrast, no adjuvant therapy was associated with survival in stage I uterine clear cell carcinoma, and further investigation to identify more effective therapies is warranted.

Purpose: Uterine papillary serous carcinoma (UPSC) is an atypical variant of endometrial carcinoma with a poor prognosis. It is commonly associated with an increased risk of extrauterine disease. The aim of this study was to investigate clinical and pathological characteristics, therapeutic methods, and prognostic factors in women with UPSC., Methods: All patients who underwent surgery for UPSC at a single high-volume cancer center between January 1995 and December 2010 were retrospectively reviewed. Patients who did not undergo surgical staging and those with mixed tumor histology were excluded. Univariate and multivariate regression models were used to identify the risk factors for overall survival (OS) and progression-free survival (PFS)., Results: A total of 46 patients were included, the majority of whom having stage I disease (IA, 13 [28.2%] and IB, 12 [26.7%]). Stages II, III, and IV were identified in 5 (10.9%), 8 (17.4%), and 8 (17.4%) women, respectively. Optimal cytoreduction was obtained in 67.3% of patients. Recurrences developed in 8 (17.4%) patients. Multivariate analysis confirmed that lymphovascular space invasion (LVSI) (odds ratio [OR] 26.83, p = 0.003) was the only independent prognostic factor for OS, whereas LVSI and optimal cytoreduction were found to be independent prognostic factors for PFS (OR 6.91, p = 0.013 and OR 2.69, p = 0.037, respectively). The 5-year overall survival rate was 63%., Conclusions: Our study demonstrated that LVSI is the only independent prognostic factor for OS, whereas LVSI and optimal cytoreduction are independent prognostic factors for PFS in patients with UPSC.

Objective: Uterine papillary serous carcinoma (UPSC) is a rare variant of endometrial carcinoma responsible for up to 40% of endometrial cancer deaths. Controversy remains regarding optimal adjuvant therapy for UPSC, with lack of randomized trials to date. The objective of this retrospective study was to evaluate clinicopathological factors and determine event-free survival and overall survival (OS) in patients with UPSC managed within a single institution., Materials and Methods: Medical and pathological records between 1987 and 2004 were reviewed at the Royal Women's Hospital, Melbourne, Australia. Cox regression analysis was used to analyze effects of clinical and histopathological variables on patient survival and survival times following adjuvant therapy. Event-free survival and OS were analyzed using the Kaplan-Meier survival curve., Results: Sixty-two patients were included; 96.8% were managed surgically and 56.5% were completely surgically staged. Myoinvasion was present in 72.6% (n = 45) of the patients.In patients with stage I disease, recurrence rate was 41.4% with a 5-year OS of 46%. In stage II, recurrence rate was 20% with a 5-year OS of 67%. In stage III, recurrence rate was 58.8% with a 5-year OS of 34%. In stage IV, recurrence rate was 71.4% with a 5-year OS of 29%.There was no significant difference in survival based on the presence of positive peritoneal cytology, positive lymphovascular space invasion or positive lymph nodes at diagnosis, and no significant difference in survival based on the type of adjuvant therapy administered. Depth of myometrial invasion was a significant determinant of poor prognosis (P = 0.027)., Conclusions: Uterine papillary serous carcinoma is an aggressive variant of endometrial cancer associated with a high proportion of advanced-stage disease at diagnosis, high recurrence rates, and low OS. In our patients, prognosis was determined by myometrial invasion and International Federation of Gynecology and Obstetrics stage at diagnosis. Randomized trials in this area are required to clarify optimal adjuvant therapy for patients with UPSC.

Objective: Despite the rarity of uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC), they contribute disproportionately to endometrial cancer deaths. Sufficient clinical information regarding treatment and prognosis is lacking. The aim of this study is to evaluate treatment outcomes in a rare cancer cohort based on the experience at two tertiary care cancer centers., Methods: Clinicopathologic data were retrospectively collected on 279 patients with UPSC and UCCC treated between 1995 to 2011. Mode of surgery, use of adjuvant treatment, and dissection of paraaoritc lymph nodes were evaluated for their association with overall survival (OS) and progression-free survival (PFS)., Results: 40.9% of patients presented with stage I disease, 6.8% of patients presented with stage II disease and 52.3% of patients presented with stages III and IV. Median follow-up was 31 months (range, 1 to 194 months). OS and PFS at 5 years were 63.0% and 51.9%, respectively. OS and PFS were not affected by mode of surgery (open vs. robotic approach; OS: hazard ratio [HR], 0.68; 95% confidence interval [CI], 0.28 to 1.62; PFS: HR, 0.78; 95% CI, 0.40 to 1.56). Adjuvant treatment was associated with improved OS in stages IB-II (HR, 0.14; 95% CI, 0.02 to 0.78; p=0.026) but not in stage IA disease. There was no difference in OS or PFS based on the performance of a paraaoritc lymph node dissection., Conclusion: Minimally invasive surgical staging appears a reasonable strategy for patients with non-bulky UPSC and UCCC and was not associated with diminished survival. Adjuvant treatment improved 5-year survival in stages IB-II disease.

Objective: To assess the pattern of failures and the survival of patients with uterine papillary serous carcinoma (UPSC)., Methods: The hospital records of 119 women with UPSC were reviewed. Surgery was the initial therapy for all the cases. The median follow-up of survivors was 133 months (range, 3-216 months)., Results: Postoperative treatment was used in 98 patients (82.4%). Adjuvant treatment was radiotherapy in 25 women, chemotherapy in 61 women, and chemotherapy plus radiotherapy in 12 women. Tumor recurred in 44 (37.0%) of the 119 patients, after a median time of 15.1 months. Relapse was symptomatic in 15 patients (34.1%), and recurrent disease involved peritoneum or distant sites in 26 (66.7%) of the 39 patients for whom the site of failure was known. Five- and 10-year survival rates were 61.8% and 54.6%, respectively. Survival was related to disease stage (P < 0.0001). Among patients with advanced tumor, 5-year survival was lower in women who had macroscopic residual disease after surgery than in those who had not (15.4% vs 37.5%; P = 0.08). Distant failures were higher in women with histologically proven positive nodes than in those with negative nodes (28.6% vs 9.1%; P = 0.048). There was a trend to better survival for patients with stage I to stage II disease who underwent chemotherapy when compared with those who did not., Conclusions: Uterine papillary serous carcinoma has an aggressive clinical behavior with a great tendency to recur especially in peritoneal and distant sites. Tumor stage is a strong prognostic factor, whereas the role of adjuvant treatment is still uncertain.

Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy in stage Ia to a wide variety of chemotherapies and radiotherapies in more advanced stages. This study presents the outcome of 109 patients with UCC or UPSC treated according to essentially the same treatment program from May 1993 to December 2004. Most patients were treated with a simple hysterectomy with no further adjuvant treatment. In stage Ia, 2/46 patients died of their disease and amongst all the stages, 30/109 patients died of their disease. These survival outcomes are comparable to or better than those presented previously.

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.

Objective: To evaluate the outcome in patients with uterine papillary serous carcinoma (UPSC)., Methods: A retrospective review of women treated for UPSC between 1995 and 2006 in Westmead Hospital, Sydney. The patients were treated with total abdominal hysterectomy, bilateral salpingo-oophorectomy and surgical staging. The majority of the patients had platinum-based adjuvant chemotherapy and radiotherapy. Sites of initial recurrence were documented. Overall survival (OS) and progression free survival (PFS) were estimated using Kaplan-Meier method. Univariate and multivariate analysis was performed using Cox regression analysis to test the effects of multiple prognostic factors on survival., Results: Two-year and five-year OS was 65% and 43%. The median OS was 39 months. Two-year and five-year PFS was 60% and 35%. Macroscopic residual disease at the completion of surgery was the only significant prognostic factor associated with worse OS on both univariate and multivariate analysis (P < 0.001). The median OS was only 11 months if patients had macroscopic residual disease, and all patients died within 18 months despite adjuvant therapies. Twenty-one patients relapsed. The site(s) of initial recurrence were: vagina (five patients), pelvic lymph nodes (four patients), abdomen (11 patients), para-aortic lymph nodes (six patients), inguinal lymph nodes (two patients) and distant metastases in seven patients. Only one of 16 patients who received vaginal brachytherapy failed in the vagina, but three of seven patients who received external beam pelvic radiotherapy failed in the vagina., Conclusion: We recommend optimal cytoreduction surgery with the aim of leaving no macroscopic disease at the end of the operation. Vaginal brachytherapy should be considered as a component of adjuvant radiotherapy. Abdominal failure was the commonest mode of failure in our cohort of patients.

To evaluate patterns of failure and overall survival for patients with surgical stage I uterine carcinosarcoma managed conservatively without adjuvant therapy. A computerized database identified 27 patients whose conditions have been diagnosed with surgical stage I uterine carcinosarcoma from 1993 to 2002. Charts were abstracted for patient demographics, tumor characteristics, recurrence, and survival. Of 27 patients, 23(85%) did not receive adjuvant therapy after undergoing total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic and paraaortic lymphadenectomy. Five patients were stage IA, 14 were stage IB, and 4 were stage IC. Fourteen patients had either poorly differentiated endometrioid carcinoma alone or in combination with papillary serous carcinoma (61%) as their epithelial tumor component. The median nodal count was 9 (range, 3-21). Eleven patients are alive without evidence of disease with a median follow-up of 63 months (range, 12-164 months). Eleven patients had recurrence with a median time to recurrence of 13 months (range, 6-39 months), and all are dead of disease. Univariate analysis demonstrated that poorly differentiated epithelial or papillary serous histologic diagnosis was the only predictor variable associated with recurrence and, consequently, death (P = 0.04). Approximately 50% of patients with surgical stage I carcinosarcoma who are observed without adjuvant therapy will experience a recurrence. Because most patients will recur distantly, systemic chemotherapy should be considered for patients with early stage uterine carcinosarcoma.

Uterine papillary serous carcinoma (UPSC) is an aggressive form of endometrial cancer that is likely to present with deep myometrial invasion and lymph vascular involvement. By the time most affected women are diagnosed, the UPSC has spread outside the uterus. Because many reports include patients who are not completely staged, the risk of recurrence in stage I patients has likely been overestimated. Recently, several large series of well-staged patients have demonstrated that survival in stage I patients is similar to that of poorly differentiated endometrioid tumors. Because of the high risk of extrauterine spread, all patients with UPSC should have an extended surgical staging procedure, including lymphadenectomy and omentectomy. Chemotherapy with or without local or regional radiation is probably the most effective adjuvant therapy in both early and advanced disease. Because patients with stage I UPSC are still at significant risk of recurrence, adjuvant therapy is often recommended for all patients. It has been difficult to conduct prospective randomized trials for patients with UPSC because of the rare nature of these cancers.

Objectives: Uterine papillary serous carcinoma (UPSC) is a rare subtype of endometrial carcinoma, characterized by a poor outcome. We sought to better analyze the effect of surgery and adjuvant therapies on this disease., Methods: A retrospective analysis was performed on the records of 138 women diagnosed with UPSC between 1986 and 2003 in the framework of the Rare Cancer Network., Results: Median age at diagnosis was 67 years. Pure UPSC was found in 107 patients and mixed histology in 30. Fifty-four patients had stage I, 20 stage II, 41 stage III and 23 stage IV disease. Median follow-up for the surviving patients was 44 months. Surgery was performed in 129 patients, after which 122 were rendered free of gross disease and comprised the adjuvant group. Of these, 23 received platinum-based chemotherapy. Radiotherapy was applied in 52 patients and 28 underwent combined chemo-radiotherapy. At last follow-up, 57 patients were alive free of disease, 10 were alive with disease, 62 died of disease, 8 died of other causes and 1 died due to toxicity. Five-year disease-free survival (DFS), disease-specific survival (DSS) and overall survival for the 122 patients treated with curative intent were 42%, 56% and 54%, respectively. In multivariate analysis, age, stage, histology and adjuvant chemotherapy were significant for DFS; age, stage and histology were significant for DSS. Radiotherapy reduced the pelvic recurrence rate from 29% to 14% (p=0.047)., Conclusions: UPSC harbours a moderate prognosis, with age, stage and histology as significant prognosticators. Conservative surgery followed by adjuvant chemotherapy and pelvic radiotherapy can be suggested as an appropriate treatment approach for patients treated with curative intent.

Objective: To assess surgical staging with systematic lymphadenectomy (LND) and adjuvant therapy in patients with stage I uterine papillary serous carcinoma (UPSC)., Methods: A single-institution, retrospective review was conducted of all surgically treated patients with primary UPSC between 1982 and 2005., Results: 42 patients (IA=15, IB=21, IC=6) were stage I. 81% (n=34) underwent LND (median 40 nodes), 69% omentectomy, and 45% peritoneal biopsies. Median follow-up was 39 months. The 5-year overall survival (OS) and progression free survival (PFS) rates were 85% and 78%. The substage 5-year OS was: IA 100%, IB 89%, IC 60%. No lymphatic recurrences (LR) were observed in 34 patients who had LND compared to 1 LR in 8 who did not undergo LND (p=NS). No recurrences were detected among the 15 patients with stage IA UPSC, irrespective of post-operative therapy. None of the 20 IB and IC patients who received radiation therapy (RT) had vaginal recurrences (VR) compared to 2 of the 7 (29%) who did not receive RT (p=0.02). A systematic LND (>20 lymph nodes) was performed in 19 stage IB and IC patients. No hematological or peritoneal recurrence (HPR) was detected in the 6 patients who received chemotherapy. In contrast, HPR were observed in 3 (23%) of 13 patients who did not receive chemotherapy., Discussion: Observation is an option for patients with stage IA UPSC confirmed by systematic LND. Patients with comprehensively staged IB and IC UPSC are candidates for chemotherapy and vaginal brachytherapy to prevent HPR and VR.

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.

Uterine serous papillary cancer (USPC) represents a rare but highly aggressive variant of endometrial cancer, the most common gynecologic tumour in women. We used oligonucleotide microarrays that interrogate the expression of some 10 000 known genes to profile 10 highly purified primary USPC cultures and five normal endometrial cells (NEC). We report that unsupervised analysis of mRNA fingerprints readily distinguished USPC from normal endometrial epithelial cells and identified 139 and 390 genes that exhibited >5-fold upregulation and downregulation, respectively, in primary USPC when compared to NEC. Many of the genes upregulated in USPC were found to represent adhesion molecules, secreted proteins and oncogenes, such as L1 cell adhesion molecule, claudin-3 and claudin-4, kallikrein 6 (protease M) and kallikrein 10 (NES1), interleukin-6 and c-erbB2. Downregulated genes in USPC included SEMACAP3, ras homolog gene family, member I (ARHI), and differentially downregulated in ovarian carcinoma gene 1. Quantitative RT-PCR was used to validate differences in gene expression between USPC and NEC for several of these genes. Owing to its potential as a novel therapeutic marker, expression of the high-affinity epithelial receptor for Clostridium perfringens enterotoxin (CPE) claudin-4 was further validated through immunohistochemical analysis of formalin-fixed paraffin-embedded specimens from which the primary USPC cultures were obtained, as well as an independent set of archival USPC specimens. Finally, the sensitivity of primary USPC to the administration of scalar doses of CPE in vitro was also demonstrated. Our results highlight the novel molecular features of USPC and provide a foundation for the development of new type-specific therapies against this highly aggressive variant of endometrial cancer.

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.

Objective: Our aim was to determine the outcomes of Stage I uterine papillary serous carcinoma (UPSC) patients with and without adjuvant therapy after comprehensive surgical staging., Methods: Patients with FIGO Stage I UPSC diagnosed from 1987 to 2000 were identified from tumor registry databases at four institutions. A retrospective chart review identified 60 women who underwent comprehensive surgical staging, including a total hysterectomy, bilateral salpingo-oophorectomy, pelvic/para-aortic lymphadenectomy, and peritoneal cytology. Fisher's exact, chi(2), and log-rank tests were used for the statistical analyses., Results: Of the 60 Stage I patients, 40 (66%) patients received no adjuvant therapy, 12 (20%) received adjuvant radiation therapy (XRT), 7 (12%) received adjuvant chemotherapy (CHM), and 1 (2%) received both XRT and CHM. There were seven recurrences in the observation group versus two recurrences in the XRT group (17% vs 16%, P = 0.9). No recurrences or deaths were observed in the CHM group. The mean disease-free survival rates for the observation and the XRT groups were 31 and 41 months, respectively. The mean overall survival rates for the observation and XRT groups were 39 and 40 months, respectively. The 5-year disease-free survival rates for the observation and XRT groups were 65 and 60%, respectively; the 5-year overall survival rates for observation and XRT groups were 66 and 59%. There was no statistical difference in overall survival among the three groups., Conclusion: In this largest reported series of surgical Stage I UPSC patients, recurrence rates were lower than those published in previous studies, suggesting a potential benefit of comprehensive surgical staging in these patients. The risk of recurrence and the mean overall survival were similar between surgical Stage I UPSC patients who were managed conservatively and those treated with adjuvant radiation therapy. These data question the benefit of radiation therapy in UPSC patients with disease confined to the uterus. Finally, given the absence of recurrences and disease-related deaths for adjuvant chemotherapy in these patients, a Phase II/III trial evaluating adjuvant chemotherapy in surgical Stage I UPSC patients should be considered.

Purpose: Uterine papillary serous carcinoma (UPSC) is an aggressive variant of endometrial carcinoma. The majority of patients with clinical Stage I UPSC are found to have extrauterine disease at the time of surgery. Most authors report survival rates of 35-50% for Stage I-II and 0-15% for Stage III and IV UPSC. Surgical treatment as the sole therapy for patients with Stage I-IV UPSC is unacceptable because of high recurrence rates. Chemotherapy, radiotherapy, or both have been added after surgery in an attempt to improve survival. However, the survival benefit to patients from such multimodality therapy remains uncertain. This study analyzes the patterns of failure in patients with FIGO Stages I-IV UPSC treated by multimodality therapy., Methods and Materials: Forty-two women with FIGO Stages I-IV UPSC who were treated by multimodality therapy were analyzed retrospectively between 1988 and 1998. Data were obtained from tumor registry, hospital, and radiotherapy chart reviews, operative notes, pathology, and chemotherapy flow sheets. All the patients underwent staging laparotomy, peritoneal cytology, total abdominal hysterectomy and salpingo oophorectomy, pelvic and para-aortic lymph node sampling, omentectomy, and cytoreductive surgery, when indicated followed by radiotherapy and/or chemotherapy. Therapy consisted of external beam radiation therapy in 11 patients (26%), systemic chemotherapy in 20 (48%), and both radiotherapy and chemotherapy in 11 (26%). The treatments were not assigned in a randomized fashion. The dose of external beam radiation therapy ranged from 45-50.40 Gy (median 45). Of the 31 patients (74%) who received chemotherapy, 18 received single-agent (58%), whereas 13 received multiagent chemotherapy (42%)., Results: Median follow-up for all patients was 19 months (range 4-72). Median follow-up for the surviving patients was 36 months (range 21-72). Their median age was 65 years. Six patients (14%) had Stage I, 8 patients (19%) had Stage II, 10 (24%) had Stage III, and 18 (43%) had Stage IV disease. Twenty-nine patients (69%) had suffered recurrence at the time of last follow-up. The actuarial failure rate at 2 and 5 years was 58% and 67%, respectively. The majority of the patients (19/29) recurred in the abdomen, vagina, or pelvis (66%). Metastases outside the abdomen were much less common as the first site of failure (17%). Twenty-five patients (60%) had died at the time of reporting; the observed survival rate at 2 years and 5 years was 52% and 43%, respectively., Conclusions: Our data suggest that, after multimodality therapy of FIGO Stage I-IV UPSC, most patients developed abdominopelvic (locoregional) failure, and the great majority of the failures occurred in the abdomen, vagina, and pelvis (66%). Abdominopelvic failure as a component of distant failure occurred in an additional 5 patients (17%). Distant failure alone occurred in 17% of the patients.We propose that future studies should combine whole abdominal radiotherapy (WART) with pelvic and vaginal boosts, in addition to chemotherapy for FIGO Stage I-IV UPSC, especially in patients with minimal residual disease, to attempt to improve the dismal prognosis of patients with UPSC.

Objective: The aim of this study was to investigate the clinicopathologic features and the outcome in patients with pure and mixed type uterine papillary serous carcinoma (UPSC), and to compare these parameters with those observed in patients with moderately and poorly differentiated endometrioid endometrial carcinoma (MPD-EEC)., Methods: The charts of 34 patients with UPSC and 30 patients with MPD-EEC, operated on between January 1995 and December 2000, were retrospectively reviewed. The UPSC group included ten cases of pure and 24 cases of mixed type UPSC (admixed with endometrioid component). All patients had undergone full surgical staging. Clinical features, surgicopathological findings, recurrence rate and recurrence-free interval were compared between the study groups., Results: Significantly more patients with MPD-EEC than with UPSC were operated on in FIGO stage I and II (p = 0.001). MPD-EEC patients were significantly older and more obese (p = 0.03 and p = 0.01, respectively) as compared with the UPSC patients. Significantly more patients with MPD-EEC presented with postmenopausal bleeding (p = 0.02), had a second primary cancer in the past (p = 0.03) and had a first degree relative with history of malignant disease (p = 0.0001). Conversely, the rates of positive abdominal cytology and cervical involvement were significantly higher in the group of UPSC (p = 0.02 and p = 0.02, respectively). Significantly more patients with UPSC were treated with adjuvant therapy (p = 0.01). No significant difference between the two study groups was observed comparing the recurrence rate, the recurrence free interval and the 3-year survival. There was also no significant difference between the pure and the mixed type UPSC, considering the clinical features and the follow-up data., Conclusion: The current study presented no significant difference in the outcome of MPD-EEC as compared with the pure and the mixed type UPSC, yet prospective studies are needed to evaluate the role of adjuvant therapy in each study group.

Background: Uterine papillary serous carcinoma (UPSC) is an uncommon, aggressive type of endometrial cancer associated with an advanced stage at initial presentation, rapid progression of disease, and poor prognosis., Methods: Twenty-three patients with UPSC were included in this study. History, treatment, follow-up, and 5-year overall survival probability (5-yr OS%) were evaluated., Results: All women underwent total hysterectomy and bilateral salpingo-oophorectomy. Positive lymph nodes were found in 10 of 17 patients who underwent pelvic lymphadenectomy. Eight patients had FIGO Stage I/II, whereas 15 patients showed Stage III or IV tumors. After surgery 5 women underwent radiotherapy, 5 chemotherapy, and 8 both radiotherapy and chemotherapy. Chemotherapy consisted of cisplatin/carboplatin plus cyclophosphamide. Adjuvant irradiation consisted of vault and external beam irradiation. The median duration of follow-up was 39.4 months (25th and 75th percentiles; 26. 1, 68.1). The median overall survival was 43.3 months (12.9, 75th percentile not reached). Three of 10 patients who received only chemotherapy or radiotherapy are alive, whereas 7/8 patients who received a combination of both are alive with no evidence of disease at the time of reporting. The 5-yr OS% was 80% in those who received radio- and chemotherapy and only 30% in those who were treated with radiotherapy alone (log rank = 0.05)., Conclusion: These results stress the need to study and evaluate the usefulness of combined chemo- and radiation therapy in patients with uterine serous papillary cancer., (Copyright 1998 Academic Press.)

A review of 355 cases of endometrial cancer treated at the KK Gynaecological Cancer Centre from June 1987 to June 1997 revealed 19 cases (5.3%) of uterine papillary serous carcinoma (UPSC), a clinically aggressive and pathologically distinct variant of adenocarcinoma which closely resembles ovarian papillary serous carcinoma. The majority of UPSC presented as late stage disease with 79% showing extrauterine disease. Twelve of 15 patients also had lymphovascular space invasion. Of the 19 cases, 15 had total hysterectomy and bilateral salpingo-oophorectomy with or without omentectomy and lymphadenectomy. Two had omental biopsy only and another 2 had dilatation and curettage only. The overall median survival in the series was 15 months. Twelve patients had died of disease (67%). Early stage disease seemed to confer a better prognosis. The poor prognosis is frequently ascribed to its tendency to present at a late stage.

Objective: Uterine papillary serous carcinoma (UPSC) is an uncommon highly malignant variant of endometrial carcinoma that histologically and clinically resembles ovarian papillary serous carcinoma. The purpose of this study was to present the conjoined experience of two regional hospitals in the south of Israel (Soroka Medical Center, Beer-Sheva and Kaplan Hospital, Rehovot) of handling this tumour., Study Design: Data from the files of 19 patients with UPSC who were managed at these hospitals between July 1991 and June 1997 were evaluated., Results: The three-year survival rate was 57.3% overall; 83.3% for Stage I and 21.2% for Stages II, III, and IV combined (P<0.02). Eighteen patients had primary surgery which included total abdominal hysterectomy and bilateral salpingo-oophorectomy and 15 (83.3%) of them received postoperative adjuvant therapy which included radiotherapy and/or systemic chemotherapy., Conclusions: The prognosis of patients with UPSC is worse than that of patients with other forms of endometrial carcinoma. Primary surgery comprised of total abdominal hysterectomy, bilateral salpingo-oophorectomy and staging is the mainstay of treatment. The type of postoperative treatment is not consistent. By and large, adjuvant pelvic radiotherapy is usually given in early-stage disease and adjuvant systemic chemotherapy is usually prescribed in advanced-stage disease.

Two cases of uterine papillary serous carcinoma are presented. Attention to propensity for deep myometrial invasion, upper abdominal spread and high relapse rate are paid. Patients require combined treatment.

The association of Turner's syndrome and endometrial carcinoma has been previously established but has never been described in conjunction with a uterine papillary serous carcinoma (UPSC). This histological variant is usually found in considerably older women and has no clear relationship to the prior use of estrogen replacement therapy. Despite presenting with stage IV disease, treated by surgery and medroxyprogesterone only, this patient has had an 8-year disease-free remission, suggesting that radical debulking of an endocrine-responsive tumor may be of considerable benefit to some women with this unfavorable histological subtype of endometrial carcinoma.
