Abstract
PURPOSE The role of adjuvant therapy for completely resected uterine sarcoma continues to be debated. Previous chemotherapy trials have shown little, if any, advantage over surgery alone, with significant added toxicity. To our knowledge, the current study is the first to evaluate adjuvant ifosfamide in completely resected uterine sarcomas. METHODS Between 1992 and 1999, 13 consecutive patients with completely resected moderate- to high-grade uterine sarcoma received three cycles of adjuvant ifosfamide (1.5 g/m(2)/day x 3 days, repeated every 28 days). Mesna was given 30 min prior to infusion. Postinfusion mesna was administered to 10 of the patients in the outpatient setting utilizing a subcutaneous infusion pump. The remaining 3 patients received traditional intravenous mesna at 4 and 8 h after infusion. RESULTS The median follow-up of the patient population was 26 months. For early-stage patients (n = 10), the 2-year progression-free survival was 60%, with a median of 26 months. The 2-year overall survival was 100%, dropping to 67% at 3 years. Early-stage patients showed an advantage in both progression-free and overall survival. Early-stage patients with mixed müllerian tumor (MMT) had a significantly longer time to progression that those with leiomyosarcoma (LMS) (2-year progression-free survival of 100% versus 33%; P = 0.019). Three patients required dose reduction secondary to grade 2-3 toxicities (neutropenia x2, nausea and vomiting x1). All significant toxicity was eliminated with dose reduction. CONCLUSIONS Adjuvant ifosfamide appears to be safe and well tolerated in patients with completely resected uterine sarcoma. It can easily be given in the outpatient setting if mesna is administered via a subcutaneous pump. Our data, consistent with previous studies in advanced sarcoma, suggest a potentially greater role for ifosfamide in MMT than in LMS.

Abstract
OBJECTIVE The benefit of primary or adjuvant irradiation in the treatment of mixed Müllerian tumors is still not clear. METHODS During 1981-1997 63 patients were referred for primary (n = 13) or postoperative (n = 50) radiotherapy. Analysis of outcome of primarily and postoperatively irradiated patients was performed separately because of different staging systems. Of 50 patients treated after surgery 29 presented in histopathologic stage I, 4 in stage II, 14 in stage III, and 3 in stage IV. Clinical stage distribution for primary treatment was stage I: n = 9, stage II: n = 1, stage III: n = 3. Forty-four patients in the postoperatively treated group and 6 in the primarily treated group received radiotherapy with a curative intent; external beam therapy was given up to 56 Gy to the pelvis combined with intravaginal or intracavitary brachytherapy. RESULTS Five-year actuarial overall survival, disease-specific survival, local control, and distant control for 50 patients receiving adjuvant irradiation was 52.9, 57. 5, 83.4, and 70.8%, in stage I: 68.4, 76.1, 95.2, and 81.7%, in stage II: 50.0, 50.0, 75.0, and 66.7%, and in stage III: 31.3, 34.1%, 70.4, and 47.6%, respectively. Four of 13 patients treated with primary irradiation achieved long-term local control. CONCLUSION These data suggest that adjuvant radiotherapy improves local control and disease specific survival in the treatment of mixed Müllerian tumors compared to data in the literature concerning treatment by surgery alone.

Abstract
PURPOSE In order to provide more information for the clinician and to analyze the impact of radiation therapy on the loco-regional disease-free interval (LRFI), disease-free interval (DFI) and specific overall survival (OS), a multicentric retrospective study of uterine sarcomas has been undertaken using cases reported to the Grup Oncològic Català-Occità (GOCO). PATIENTS AND METHODS One hundred three patients were selected for this study with a median follow-up period of 49 months. Patients were restaged using the FIGO classification for endometrial adenocarcinoma. Radiotherapy was administered postoperatively to the entire pelvis in 52% of cases (54/103) and was combined with brachytherapy in 24 patients. Mean given dose was 48 Gy, with a 95% confidence interval of 45 to 50 Gy. Variables have been tested for homogeneity between hospitals. Univariate and multivariate analyses have also been carried out. RESULTS Mean age of the selected patients was 59 years (range 35-84). Stages were distributed as follows: 66 patients (64%) in Stage I; 16 in Stage II (15.5%); 12 in Stage III (11.5%); 9 patients in Stage IVa (9%). Pathological distribution was 41.5% leiomyosarcoma, 39% mixed Mullerian tumours, 16.5% stromal sarcomas, and 2.9% of a miscellaneous group. Overall survival for the entire group was 63.7% and 56% at 2 and 5 years, respectively. Probability of LRFI reached 59.8% at 2 years and 57.4 at 5 years. The DFI at 2 and 5 years were 52.9 % and 48.7%, respectively. The LRFI probability was 41% and 36% at 2 and 5 years, respectively, without radiotherapy and reached 76% at 2 and 5 years among those patients treated with radiotherapy. There was also an increase in DFI probability because of the effect of radiotherapy, from 35% to 68.5% and from 33% to 53% at 2 and 5 years, respectively. The overall survival probability for patients treated with radiotherapy was 76% and 73% at 2 and 5 years, respectively and 51% at 2 years and 37% at 5 years without radiotherapy. Multivariate analysis demonstrated that radiotherapy improved LRFI, DFI, and overall survival. CONCLUSION We conclude that postoperative radiotherapy in our series of patients diagnosed with uterine sarcoma has an impact on loco-regional and disease-free progression intervals and survival.

Abstract
PURPOSE With a retrospective study at a single institution, we propose to analyze the prognosis factors and adjuvant treatment for uterine sarcomas. MATERIALS AND METHODS From 1975 to 1995, 73 uterine sarcomas were treated at the Institut Curie, corresponding to 61 T1, 5 T2, and 8 T4 tumors. Thirteen patients had metastatic disease at the time of diagnosis. The mean age was 58 years. In 71% of patients, the presenting sign was bleeding. This series consisted of 44% leiomyosarcomas (LMS), 19% endometrial stromal sarcomas (ESS), and 31% carcinosarcomas or mixed mesodermal sarcomas (MMS). For the grading classification, we used the classification of the Sarcoma Group of the French Federation of Cancer Centres for soft tissue sarcomas. Of the patients, 66% presented a high-grade tumor. RESULTS The median overall survival was 42 months, with a 5-year survival of 45%. Histological grade, FIGO stage, histology types, and menopausal status were the four independent factors in multivariate analysis. Eighteen patients relapsed locally (25.7%), with 77% central pelvic sites. Patients with radiotherapy and ESS had better local control in multivariate analysis. Thirty-four patients developed metastases (48.6%), mainly pulmonary (58.8%). Eight patients presented with peritoneal disease. High grades and LMS had the worst survival without metastasis in multivariate analysis. CONCLUSION This study validated our classification for sarcoma grading and confirmed the finding of worst prognosis for LMS and the importance of radiotherapy in local control.

Abstract
BACKGROUND The role of radiotherapy in the treatment of uterine sarcoma still is not clear. Data from the literature advocating adjuvant radiotherapy most often are based on very small patient groups, whereas larger epidemiologic studies, which appear to show no benefit for the additional radiotherapy, lack information regarding clinical data influencing the choice for adjuvant irradiation. METHODS During 1981-1992, 72 patients were referred for postoperative radiotherapy. Histologic diagnoses were leiomyosarcoma (LMS) in 30 patients, endometrial stromal sarcoma (ESS) in 11 patients, mixed müllerian tumors (MMT) in 28 patients, and other sarcoma types in 3 patients. The 1988 International Federation of Gynecology and Obstetrics classification for endometrial carcinoma was applied retrospectively. Forty patients presented with Stage I disease, 9 with Stage II, 17 with Stage III, and 6 with Stage IV. External beam therapy was given with a cobalt-60 unit using a rotation technique with 2 separate arcs in daily fractions of 2 gray (Gy), up to a total dose of 56 Gy to the pelvis. Brachytherapy was given to the vaginal vault either with 2 radium applications (median: 1600 milligram-hours to the applicator surface) or, in the majority of cases, with 3 fractions of high dose rate afterloading applications (iridium-192, 10-Curie source) with 7 Gy each to an isodose 7.5 mm from the applicator surface. RESULTS The 5-year actuarial overall survival, disease specific survival, and local control rates for 72 patients were 52.3%, 58.5%, and 77.9%, respectively; in Stage I patients they were 74.8%, 84.6%, and 94.4%, respectively; in Stage II patients they were 53.3%, 53.3%, and 88.9%, respectively; in Stage III patients they were 15.7%, 17.9%, and 55.5%, respectively; and in Stage IV patients they were 0%, 0%, and 0%, respectively. For LMS, the 5-year actuarial overall survival, disease specific survival, and local control rates were 49.4%, 52.0%, and 76.0%, respectively; for ESS they were 81.8%, 81.8%, and 90.9%, respectively; and for MMT they were 42.3%, 54.9%, and 72.4%, respectively. CONCLUSIONS These data suggest that adjuvant radiotherapy is an effective treatment for uterine sarcoma with regard to disease specific survival in patients with early stage disease and increases local control, even in patients with advanced stage disease.

Abstract
BACKGROUND Leiomyosarcoma of the uterus is a rare malignancy with a poor prognosis. Total abdominal hysterectomy is considered the treatment of choice. Occasionally, the diagnosis is made on myomectomy specimen, and in young patients the role of conservative management is not well defined. PATIENTS AND METHODS Between 1982 and 1996, eight patients with a diagnosis of uterine leiomyosarcoma following myomectomy were conservatively managed at our institution. Median age of the patients was 29 years (range 19-32 years), and all were nulliparous. The tumor was confined to a myoma in all patients. Patients were adequately informed about the risk and were submitted to strict follow-up including pelvic examination, hysteroscopy, ultrasonography, chest X-ray, and abdominopelvic MRI or CT scan. RESULTS Mean mitotic count of leiomyosarcomas was 6 per 10 HPF, ranging between 5 to 33. At a median follow-up of 42 months three pregnancies were recorded. Two patients had a spontaneous delivery at term. The third patient had diagnosis of recurrent disease at the time of cesarian section. Despite further surgery and chemotherapy, she died of disseminated disease 26 months after diagnosis. The remaining seven patients are alive and well. Two patients received a second surgical procedure after diagnosis of leiomyosarcoma, 24 and 16 months after primary operation. Both were found to have leiomyomas. CONCLUSIONS Selected cases of uterine leiomyosarcoma might be managed conservatively in young nulliparous women desiring pregnancy. A strict follow-up is mandatory, and at the completion of the reproductive life, a demolitive procedure could be considered.

Abstract
Since tamoxifen is widely used in breast cancer treatment and has been proposed for the prevention of breast cancer, its endometrial iatrogenic effects must be carefully examined. We have investigated the association between endometrial cancer and tamoxifen use or other treatments in women treated for breast cancer in a case-control study. Cases of endometrial cancer diagnosed after breast cancer (n = 135) and 467 controls matched for age, year of diagnosis of breast cancer and hospital and survival time with an intact uterus were included. Women who had received tamoxifen were significantly more likely to have endometrial cancer diagnosed than those who had not (crude relative risk = 4.9, p = 0.0001). Univariate and adjusted analyses showed that the risk increased with the length of treatment (p = 0.0001) or the cumulative dose of tamoxifen received (p = 0.0001), irrespective of the daily dose. Women who had undergone pelvic radiotherapy also had a higher risk (crude relative risk = 7.8, p = 0.0001). After adjusting for confounding factors, the risk was higher for tamoxifen users (p = 0.0012), treatment for more than 3 years (all p < 0.03) and pelvic radiotherapy (p = 0.012). Women who had endometrial cancer and had received tamoxifen had more advanced disease and poorer prognosis than those with endometrial cancer who had not received this treatment. Our results suggest a causal role of tamoxifen in endometrial cancer, particularly when used as currently proposed for breast cancer prevention. Pelvic radiotherapy may be an additional iatrogenic factor for women with breast cancer. Endometrial cancers diagnosed in women treated with tamoxifen have poorer prognosis. Women who receive tamoxifen for breast cancer should be offered gynaecological surveillance during and after treatment. A long-term evaluation of the risk-benefit ratio of tamoxifen as a preventive treatment for breast cancer is clearly warranted.

Abstract
AIM The authors analyzed in a retrospective manner the prognostic significance of p53 and mdm-2 expression, DNA ploidy, S-phase fraction (SPF), and traditional clinical and pathological prognostic factors in patients with uterine leiomyosarcomas. MATERIAL Forty-nine patients were diagnosed with uterine leiomyosarcoma (25 stage I, 4 stage II, 8 stage III, and 12 stage IV). DNA flow cytometric analysis and immunohistochemical staining for p53 and mdm-2 were performed on paraffin-embedded archival tissue from the uterine tumors. RESULTS Of the 49 patients, 35 (71%) died of disease and 2 died of intercurrent disease. The 5-year survival rate was 33%. FIGO surgical stage, DNA ploidy, SPF, mitotic index, cellular atypia, and tumor grade obtained significance (P < 0.05) in a univariate survival analysis of the leiomyosarcomas. In a multivariate analysis with survival as the end point, stage was found to be the most important factor (P = 0.007); DNA ploidy (P = 0. 045) and SPF (P = 0.041) also had independent prognostic significance. For FIGO stage I tumors, DNA ploidy (P = 0.04) and tumor grade (P = 0.01) were statistically significant in a univariate analysis, while only grade had independent prognostic significance (P = 0.01) in a multivariate analysis. In a univariate analysis including only FIGO stage I and II tumors with disease-free survival as the end point, p53 overexpression (P = 0.0016), DNA ploidy (P = 0.042), and tumor grade (P = 0.008) obtained significance. In a multivariate analysis, only p53 had independent statistical significance (P = 0.01). All p53 immunopositive stage I-II tumors recurred within 28 months from diagnosis. CONCLUSION This study found that stage represents the most important prognostic factor for uterine leiomyosarcomas. DNA ploidy and SPF had independent prognostic value. DNA flow cytometry is useful in gaining additional prognostic information. In stage I patients, tumor grade gives significant information regarding clinical outcome. In addition, p53 overexpression may predict a higher risk of recurrence in early stage leiomyosarcomas.

Abstract
Thirty-eight patients with Stage I and II uterine carcinosarcoma were treated by surgery with and without whole-pelvic irradiation (WPI) at our institution from 1975 to 1993. Ten patients (8 Stage I and 2 Stage II) were treated with surgery alone, while 28 patients (20 Stage I and 8 Stage II) received WPI in addition to surgery. With a median follow-up of 75 months (range 25-220 months), a trend toward a decreased rate of pelvic recurrence in those receiving WPI (6/28, 21%) compared to those treated with surgery alone (5/10, 50%) was observed (P = 0.09). There was no difference in the rate of distant recurrence between those receiving WPI (12/28, 43%) and those who did not (4/10, 40%) (P = 0.9). There was also no difference in the 2- and 5-year Kaplan-Meier survival estimates for the patients receiving WPI (79 and 59%, respectively) compared to those who did not receive WPI (60 and 60%, respectively) (P = 0.84). In this small series, the addition of whole-pelvic irradiation to primary surgery did not improve survival; however, a trend toward improved pelvic control was observed, suggesting a possible benefit for pelvic irradiation that should be studied in future trials.

Abstract
Our study's aim was to determine the incidence of uterine sarcomas in New York City (NYC) and evaluate trends in frequency, treatment, and survival of carcinosarcomas in two Brooklyn hospitals. Population-based cancer registry data for 1976-1985 were used to calculate the incidence of uterine sarcomas in NYC women. Medical records and histology slides of carcinosarcomas at two central Brooklyn hospitals from 1960 to 1995 were reviewed. The incidence of uterine sarcomas in black and white women in NYC was 33.4 and 17.0 per million (P < 0.01). Among 97 women with carcinosarcomas diagnosed in 1960-1995, 75% were diagnosed preoperatively, 82% had a hysterectomy, and 45% of those in clinical stage I were upstaged. Predictors of mortality included the presence of extrauterine extension, deep myometrial invasion, vascular space invasion, and gross residual disease, with only the first two being independent predictors of survival in a multivariate analysis. Adjunctive therapy shifted from radiation in 1960-1969 to cisplatin-based chemotherapy after 1980. In surgical stage III, survival increased significantly between 1960-1979 and 1980-1995, but improvement could not be ascribed to particular therapies. The incidence of uterine sarcomas in black women was twice that in white women. Surgical staging including omentectomy is recommended in the management of carcinosarcomas. Modern medical care may have improved the short-term prognosis of carcinosarcomas.

Abstract
Sarcomatoid Carcinomas are rare tumors composed of mixed malignant epithelial and mesenchymal cells. Only one case is reported in the colon, up to date. We describe the second case in an 86-year-old woman. The tumor, replacing the intestinal wall, consisted of carcinomatous and sarcomatous areas. The former was composed of differentiated superficial adenocarcinoma and of infiltrating epithelioid undifferentiated solid portion. The latter was mostly composed of undifferentiated spindle cells with focal chondrosarcomatous and pleomorphic anaplastic areas. A strong Cytocheratin (CK) and Epithelial Membrane Antigen (EMA) immunoreactivity (IR) with focal CA 125 positivity was detected in differentiated adenocarcinomatous areas. Solid carcinoma-like areas coexpressed CK and Vimentin (VIM). The sarcomatous spindle-cell component of the tumor was largely VIM positive, with focal CK IR. Both polyclonal and monoclonal antibodies for Carcino-Embryonic Antigen (CEA) did not display any reaction.

Abstract
BACKGROUND Malignant neoplasms of the structural tissues, consisting mostly of soft tissue sarcomas, are morphologically diverse and rarely treated for epidemiologic purposes as individual entities. Our understanding to date of the pattern of occurrence of sarcomas is based largely on reports of limited individual clinic experience or case-control studies, each driven by a single hypothesis, and there have been virtually no descriptions according to specific morphologic type. METHODS The accumulated coverage of the SEER populations offers an opportunity to correct this deficit. Each of the diagnoses has been reported and coded using a single set of rules and described in relation to the population at risk in terms of age, sex, race, calendar period, anatomic location, and outcome. In addition, each morphologic type has been compared with each of the others with respect to the pattern of occurrence and survival. RESULTS For most of the individual morphologic entities, the pattern of occurrence is specific and unlike other patterns. Differences according to anatomic site, age, sex, race, and period-specific survival were found. Partly because of changes in diagnostic criteria over the years, differences in secular trend, other than that for Kaposi's sarcoma, could not be verified. Although some types of sarcoma may have important genetic determinants, there is evidence of environmental causation in others; for some varieties both genetic and environmental factors may operate. There is no evidence of improvements in survival. CONCLUSIONS The most likely basis for the observed patterns are morphology-specific differences in etiology and growth phase. Each of the entities should be considered etiologically distinct and should be studied individually whenever possible.

We have analysed the medical records and diagnostic imaging of 76 patients presenting to this hospital for treatment of uterine sarcoma between 1970 and 1990. Patients were divided into those presenting before 1980 (n = 22) and after 1980 (n = 54), when sectional imaging (ultrasound, CT scanning) and more modern radiotherapy and chemotherapy were introduced. No survival difference was observed between these two groups. In those patients presenting after 1980, the median age was 54 years (range 18-80), and median survival 22 months from initial diagnosis. Factors associated with a significantly improved survival included low grade (although not histological type) of initial tumour (p = 0.001) and Stage I disease at presentation (p = 0.006). In 17 patients receiving pelvic radiotherapy following initial surgery, both the time to relapse (p = 0.005) and overall survival (p = 0.045) were increased. Adjuvant chemotherapy in 19 patients did not improve outcome. Most diagnoses of relapse were established clinically; they occurred most frequently in the pelvis, followed by lung and abdomen. Pulmonary relapse was accompanied by spontaneous pneumothorax in two cases. Bone and brain metastases were uncommon (< 10%). Following diagnosis of relapse, the median survival was 9 months, with the outcome significantly worse if multiple metastatic sites were involved (p < 0.001). No survival benefit was demonstrated from either local radiotherapy or combination chemotherapy once relapse had occurred. Prognostic factors and current policies for the diagnosis and management of uterine sarcomas are discussed.

Abstract
OBJECTIVE To determine the survival data for the various tumour types of uterine sarcoma and determine the influence of various prognostic factors on survival. DESIGN Retrospective analysis of all uterine sarcoma cases registered in the 15 year period 1967-1981. SETTING West Midlands Regional Cancer Registry, serving a catchment area of 2.6 million women. SUBJECTS 423 women registered as having a uterine sarcoma; 367 of these were associated with the two main histological types, leiomyosarcomas (LMS) and mixed mesodermal tumours (MMT). MAIN OUTCOME MEASURES Duration of survival was taken as the primary endpoint. RESULTS The overall 5-year survival for uterine sarcomas in this series was 31%, with the major prognostic indicator being tumour stage. Survival for mixed mesodermal tumours is similar to other sarcomas despite a tendency towards less differentiation, wider dissemination and a greater age of the patient at diagnosis. Multivariate analysis shows that for cases with similar stage, age and grade, mixed mesodermal tumours have a better prognosis than leiomyosarcomas. CONCLUSIONS These results demonstrate the danger of considering each variable in isolation when the relation between variables can lead to spurious significance or lack of significance because of the imbalances in the numbers between groups of prognostic importance. This study underlines the need for an adequate inspection of the intra-abdominal contents at the time of hysterectomy for uterine fibroids.
