Uterine papillary serous carcinoma: evaluation of multimodality treatment with abdominopelvic radiotherapy and chemotherapy

Abstract.   Steed H, Manchul L, Rosen B, Fyles A, Lockwood G, Laframboise S, Murphy J, Milosevic M, Chapman W, Oza AM. Uterine papillary serous carcinoma: evaluation of multimodality treatment with abdominopelvic radiotherapy and chemotherapy. Int J Gynecol Cancer 2006; 16(Suppl. 1): 278–285.
The aim of this study was to compare overall survival (OS), progression-free survival (PFS), and relapse patterns between different modalities of treatment for uterine papillary serous carcinoma (UPSC). A retrospective review of 124 patients with pathologically confirmed UPSC was performed, of whom, 97 patients were eligible for study. Postoperative treatment groups included adjuvant radiotherapy consisting of whole abdomen and a pelvic boost (abdominopelvic radiotherapy [APRT]) (55 patients), paclitaxel and carboplatin chemotherapy (CT) for six cycles followed by APRT (18 patients), CT only (5 patients), and 19 patients were observed without postoperative adjuvant therapy. Three-year OS was 81% and 63% for the CT followed by APRT and APRT alone, respectively ( P = 0.11). After controlling for stage, the group treated with APRT alone had significantly decreased OS and PFS compared to the CT/APRT group (HR 3.6; 1.3–9.8; P = 0.01) and (HR 2.9; 95% CI 1.1–7.3; P = 0.03), respectively. Within the limitations of a retrospective study, the results of this study indicate that multimodality postoperative treatment with paclitaxel and a platinum-based CT followed by APRT may increase the survival of patients with UPSC. However, further prospective studies using these combined modalities are needed to confirm these findings.     

Uterine papillary serous carcinoma：Its clinical and fundamental study

Uterine papillary serous carcinoma (UPSC) was established as a distinct type of endometrial carcinoma by Lauchlan in 1981 and Hendrickson et al in 1982, and accounted for 1% ～ 10% of endometrial cancers. Theoccurencer of papillary patterns of endometrial adenocarcincma had been reportedly recognized since 1900, while until the late 1970s several authors have had described a variant of papillary endometrial cancer. UPSC is a morphologically unique variant of endometrial carcinoma that is pathologically defined by the presence of high nuclear grade, distinct papillary architechtural changes, psammoma bodies, and extensive lymph- vascular space invasion. CA125 is often mentioned a usefultumor marker either for diagnosis before starting treatment or in monitoring recurrence. The ptimal treatment of UPSC is controversial and appears to be dependent upon the stage of the disease. Primary surgery comprised of TAH/BSO and complete staging is the mainstay of treatment. The patients with recurrent UPSC in many studies were treated with various combinations of surgery, radiation therapy, and chemotherapy. The molecular basis for the general poor response of UPSC to adjuvant chemotherapy and radiotherapy is not well understood. UPSC tumors are more often aneuploid and contain overexpressed mutant p53 protein as compared to encdometrioid adenocarcinoma. Unlike patients with adenocarcinoma of the endomeutrium, women with UPSC were less likely to be obese, hypertensive, or diabetic.     

Uterine papillary serous carcinoma: Patterns of failure and survival

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.     

Immunohistochemical characterization of endocervical papillary serous carcinoma

Abstract.   Nofech-Mozes S, Rasty G, Ismiil N, Covens A, Khalifa MA. Immunohistochemical characterization of endocervical papillary serous carcinoma. Int J Gynecol Cancer 2006; 16(Suppl. 1): 286–292.
Endocervical adenocarcinomas are rare and aggressive neoplasms. Papillary serous endocervical adenocarcinomas are the rarest form of endocervical adenocarcinomas. This tumor exhibits morphologic similarities to its counterparts commonly seen in the endometrium, fallopian tubes, ovaries, and peritoneum, which are known to have an aggressive behavior. Because of the rarity of this tumor, little is known about its immunophenotyping. In this study, we included ten cases of papillary serous carcinomas arising from the uterine cervix (PSCC) diagnosed in the absence of a primary endometrial malignancy. We studied their immunohistochemical profile, using a panel of antibodies against Ki67, bcl-2, p53, carcinoembryonic antigen (CEA), and CD10, and compared them to 20 consecutive cases of cervical adenocarcinoma of conventional cell subtypes (CAC) (15 mucinous, 3 adenosquamous, and 2 endometrioid). Immunostaining was recorded semiquantitatively. Patients with PSCC ranged in age from 27 to 79 years (mean = 51.6 ± 19.1), while the conventional cell subtypes control group were 28–90 years old (mean = 47.5 ± 16.9). Only p53 and CEA immunostaining significantly correlated with the PSCC morphology ( P = 0.001 and P = 0.016, respectively) as shown by Cochran–Mantel–Haenszel Statistics (Modified Ridit Scores). PSCC is a distinctive immunophenotypic subtype of endocervical adenocarcinoma with significantly higher p53 and lower CEA reactivity than other more common histologic subtypes.     

Non-ovarian peritoneal papillary serous carcinoma with high CA125 levels

Summary A patient with peritoneal papillary serous carcinoma involving the colon and omentum is presented. Following palliative right-sided hemicolectomy and partial omentectomy, chemotherapy was given. The patient had a second look operation after 6 months when a pelvic clearance was done and histology revealed some residual tumor in one mesosalpinx. She was well and clinically free of recurrence after a further 6 months. Serum CA125 and CEA levels were measured and CA125 levels remained high throughout.     

A review of the pathology and management of uterine papillary serous carcinoma and correlation with outcome

Uterine papillary serous carcinoma (UPSC) accounts for 10% of endometrial carcinomas but a higher proportion of deaths due to its aggressive nature and poor response to chemotherapy and radiotherapy. In order to add to the knowledge of UPSC in the literature and to review our local practices, we examined the pathology, medical records, and management of all cases of UPSC (67 patients) treated in South East Scotland over a 10-year period and also evaluated the prognostic significance of the percentage of UPSC in endometrial pipelle and hysterectomy specimens. Although only 63% of initial diagnostic biopsies were reported to contain UPSC, rereview of the cases revealed UPSC in 98.5% of the preoperative biopsies. The percentage of UPSC in the tumors did not affect the outcome. Stage, positive omentum, and treatment with external-beam +/- intracavitary radiotherapy were significantly correlated with overall survival and progression-free survival by univariate analysis, but only stage (P < 0.01) was correlated with outcome on multivariate analysis. Chemotherapy did not affect outcome. UPSC may be difficult to diagnose in preoperative biopsies, particularly when present as part of a mixed tumor. Even a small percentage of UPSC in a diagnostic biopsy or hysterectomy specimen is correlated with a poor prognosis. This study emphasizes the need of a cooperative, prospective study on this distinct uterine carcinoma.     

Outcomes in surgical stage I uterine papillary serous carcinoma

OBJECTIVE: The optimal management of patients with stage I uterine papillary serous carcinoma (UPSC) is unclear. We sought to determine whether outcomes of women with surgical stage I UPSC differ with and without adjuvant therapy. METHODS: Retrospective multi-institution analysis of women with stage I UPSC surgically staged from 1976 to 2006. Inclusion criteria: comprehensive staging procedure including hysterectomy, bilateral salpingo-oophorectomy, selective pelvic/aortic lymphadenectomy, peritoneal cytology. Recurrence and survival were analyzed using Kaplan-Meier method. RESULTS: Of 83 women with stage I UPSC, 36 (43%) received adjuvant therapies (23% radiotherapy, 3% chemotherapy, 15% chemotherapy and radiotherapy, 2% progestins). Three-year overall (OS) and progression-free survival (PFS) were 80% and 68%, respectively. Three-year OS and PFS by adjuvant treatment were observation (N=47) 86% and 78%, radiotherapy (N=17) 63% and 44%, chemotherapy with or without radiotherapy (N=17) 92% and 76%, respectively. Of the 18 recurrences, 9 (50%) included an extrapelvic component. Local recurrence was 2/30 (7%) following adjuvant radiotherapy and 7/53 (13%) without radiotherapy (p=0.48). Recurrence was higher in stage IB/IC (15/51, 29%) compared to stage IA (3/32, 9%). There has been one recurrence (5%) among the 22 women observed with stage IA disease. CONCLUSION: In this largest reported series of women with surgical stage I UPSC, the high recurrence (29%) among patients with stage IB/IC disease highlights the need for clinical trials to test new therapeutic approaches. Surgically staged patients with IA disease had good prognosis. These data suggest that radiotherapy alone is not effective, that systemic therapy is needed, and that observation could be considered in patients with stage IA disease.

Mixed serous—endometrioid carcinoma of the uterus: pathologic and cytopathologic analysis of a high-risk endometrial carcinoma

A review of the pathology and cytopathology of 295 endometrial adenocarcinomas treated surgically at King Edward Memorial Hospital for Women, with full 5-year follow-up, revealed 16 cases of pure serous carcinoma (USC), 10 cases of mixed serous and endometrioid carcinoma with a predominant serous component (mixed USC-EAC) and six cases of mixed serous and endometrioid carcinoma with a predominant endometrioid component (mixed EAC-USC). The mixed carcinomas may be characterized microscopically by classical serous features side by side with classical endometrioid features, or additionally by features intermediate between the two. Many of these features are reproduced in preoperative cervicovaginal smears. USC and mixed USC-EAC were found to be indistinguishable clinically and prognostically, with an identical corrected 5-year survival of 40%, although numbers are small. Mixed EAC-USC (which contained 10–25% serous differentiation in this series), however, were similar in many respects to a control population of 95 EAC of Grade 2 and 3. The corrected 5-year survival in these two groups was 67% and 79%, respectively, which is not statistically significant in this small series. This study suggests that the behavior of a mixed tumor containing 50% or more serous differentiation is similar to that of pure serous carcinoma, and that the behavior of a mixed tumor containing less than 25% serous differentiation is similar to that of the other component. Given the poor correlation between pathologic findings in curettage and subsequent hysterectomy specimens, however, identification of any significant serous element in curettage material may prove vital in optimizing surgical and adjuvant therapy.     

The efficacy of adjuvant platinum-based chemotherapy in Stage I uterine papillary serous carcinoma (UPSC)

OBJECTIVE: To determine the efficacy of adjuvant platinum-based chemotherapy in Stage I uterine papillary serous carcinoma (UPSC). METHODS: A retrospective multi-institutional investigation was performed to identify surgically staged patients with Stage I UPSC who were (1) treated after surgery with 3-6 courses of platinum-based chemotherapy without radiation from 1990-2003, and (2) followed for a minimum of 12 months, or until recurrence. RESULTS: Six patients (IA-2, IB-3, IC-1) were treated with carboplatin (AUC 6) or cisplatin (50 mg/m2) alone. One patient recurred to the vagina, was treated with chemo-radiation, and is alive and well at 122 months. One patient recurred to the lung, liver, and brain, and died of disease at 24 months. The remaining 4 patients are alive with no evidence of disease 15-124 months (mean 62 months) after treatment. Two patients (IB-1, IC-1) were treated with cisplatin (50 mg/m2) and cyclophosphamide (1000 mg/m2), and both are alive and well with no evidence of disease 75 and 168 months after treatment. Twenty-one patients (IA-5, IB-13, IC-3) were treated with a combination of carboplatin (AUC 6) and paclitaxel (135 mg/m2-175 mg/m2). One patient recurred to the vagina after 3 cycles of carboplatin/paclitaxel, and was treated with chemo-radiation. She is now without evidence of disease 10 months after treatment. At present, all 21 patients with Stage I UPSC treated following surgical staging with carboplatin/paclitaxel chemotherapy are alive and well with no evidence of disease 10-138 months (mean 41 months) after treatment. CONCLUSION: Combination carboplatin/paclitaxel chemotherapy following surgery is effective in the treatment of Stage I UPSC.     

Complete response to docetaxel and carboplatin combination chemotherapy for a stage IV uterine papillary serous carcinoma: a case report

We report a case of a stage IV uterine papillary serous carcinoma (UPSC) with multiple organ metastases. The patient was treated with docetaxel and carboplatin combination chemotherapy. After five courses, uterine tumor, Douglas tumor, lymphadenopathy, and distant metastases on magnetic resonance imaging or computed tomography scan were completely resoluted. Moreover, endometrial biopsy showed no carcinoma tissues after six courses. We suggest that this regimen may be effective for treatment of advanced-stage UPSC.     

Prognosis of papillary serous, clear cell, and grade 3 stage I carcinoma of the endometrium

OBJECTIVE: The purpose of this study was to evaluate patients with uterine papillary serous carcinoma (UPSC), clear cell (CC), and grade 3 endometrioid (G3) surgically stage I endometrial cancer. METHODS: The 25th Annual Report (AR) of FIGO was used to identify patients with endometrial cancers who were surgically staged. For comparison, all cancers reported were evaluated with particular interest in patients with stage I UPSC, CC, and G3. Incidence, substage, post-surgical treatment, and survival were identified. RESULTS: Of 5694 endometrial cancer patients reported to the AR, 3996 (70%) were surgically stage I. There were 148 UPSC, 59 CC, and 325 with G3 lesions. UPSC and CC represent 5.2% of all stage I cancers while 8.1% are G3. Although there were greater number of UPSC, CC, and G3 with extrauterine disease, about 50% of UPSC and CC were stage I. This compares to 81% for G1, 68% for G2, and only 42% for G3. There were more IA cancers with UPSC and CC than G3 (22%, 33%, and 17%, respectively). Survival (5 years) for UPSC and CC was 72% and 81%, respectively, compared to 76% for G3 lesions. Postoperative radiation improved survival somewhat (6-8%) but the difference was not significant. CONCLUSION: UPSC and CC histotypes when diagnosed as stage I have a better survival than commonly perceived and equal to G3 endometrioid cancers. Postoperative radiation improves survival but not significantly so. The role of chemotherapy has not been defined.     

Long-term survival after paclitaxel plus platinum-based combination chemotherapy for extraovarian peritoneal serous papillary carcinoma: is it different from that for ovarian serous papillary cancer?

The purpose of this study was to compare the effect of paclitaxel plus platinum-based chemotherapy in the treatment of extraovarian peritoneal serous papillary carcinoma (EPSPC) and ovarian serous papillary cancer (OSPC). Only the patients treated with initial surgery plus postoperative adjuvant chemotherapy and having FIGO stage IIIC disease with omental and/or peritoneal involvement were analyzed. Thirty-two patients with EPSPC and 43 with OSPC were included in this study. The median age, mean CA-125, and volume of ascitis were higher in patients with EPSPC. There was no significant difference between the two groups with respect to other prognosticators. The median overall survival (OS) durations were 30 months (95% CI 24.8-35.3) in patients with EPSPC and 28 months (95% CI 21.1-34.9) in those with OSPC (P= 0.35). The 3-year OS rates in the patients and controls were 28% and 31%, respectively (P= 0.84). In patients with EPSPC, only optimal cytoreduction was significantly related to progression-free survival and OS durations as a prognostic factor. In the EPSPC group, 65.5% of the patients (19/29) had lymphatic involvement, compared to 88.4% (38/43) in the OSPC group (P= 0.02). As an adjuvant therapy, the paclitaxel plus platinum-based combination regimen had similar effects on survival in the EPSPC and OSPC groups.
