Survival after multimodality treatment for stage IIIC endometrial cancer

OBJECTIVE: Our purpose was to review our results of multimodality treatment of lymph node metastasis in endometrial cancer (stage IIIC). STUDY DESIGN: All patients underwent surgical staging for endometrial cancer with complete pelvic and aortic lymphadenectomy. All macroscopic nodal metastases were resected. Patients with microscopic nodal metastasis received adjuvant teletherapy, whereas those with macroscopic nodal metastasis received chemotherapy (carboplatin AUC 5 and paclitaxel 135 mg/m2 every 3 weeks for 6 courses) followed by teletherapy. RESULTS: Twenty-one patients had stage IIIC disease, and one had stage IVB (inguinal nodal metastasis). Sixty-four percent of tumors were poorly differentiated. Fifty-five percent of patients had pelvic nodal metastasis only and 41% had macroscopic nodal metastasis. At a median follow-up of 3.8 years, 32% of patients had recurrence, all extrapelvic. Overall mean survival was 48 months and progression-free survival was 40 months. Overall survival for microscopic nodal metastasis was >60 months versus 35 months for macroscopic metastasis. Overall survival for pelvic nodal metastasis was 53 months versus 42 months for aorticinguinal metastasis. There were no complications from lymphadenectomy, a 22% chemotherapeutic toxicity, and a 14% radiation toxicity. CONCLUSION: Our surgical, chemotherapeutic, and radiation treatment protocol for stage IIIC endometrial cancer produced minimal toxicity and good survival.     

Hysteroscopy to detect Stage IA well-differentiated endometrioid adenocarcinoma of the endometrium

BACKGROUND: Well-differentiated Stage IA endometrial carcinoma may be managed conservatively with progestin treatment. However, even advanced imaging methods cannot overcome limitations in the correct determination of the absence of early microscopic myometrial invasion by endometrial carcinoma. Hysteroscopy has not yet been investigated as a tool for this purpose. METHODS: Of 97 patients with well-differentiated endometrioid adenocarcinoma, 87 whose tumors were clinically confined to the uterine corpus were enrolled for inclusion in this study. The preoperative hysteroscopic appearance was correlated with the histological findings of the hysterectomy specimen. RESULTS: Post-surgical FIGO stage was Stage IA in 36 cases, IB in 29, IC in 16, IIA in one, and Stage IIIA/C in five cases. Before surgery, the growth pattern of the disease was hysteroscopically diagnosed as pedunculated in 69.0% and sessile nodular in 31.0%. Surface ulceration was observed in 23.3% of the pedunculated tumors and in 74.1% of the sessile tumors ( p < 0.0001), and in 39.1% of all tumors. The incidence of absent myometrial invasion was significantly higher in the pedunculated tumors (56.3%) than in the sessile tumors (3.7%) ( p < 0.0001) and was higher in the nonulcerated tumors (64.2%) than in the ulcerated tumors (5.9%) ( p < 0.0001). When the statistical parameters were calculated in combination with the tumor growth pattern and the absence or presence of ulceration, the nonulcerated pedunculated growth pattern had a sensitivity of 92% and a positive predictive value of 72% for correct selection of Stage IA disease with no myometrial invasion. CONCLUSION: Well-differentiated endometrioid adenocarcinoma was categorized by hysteroscopy into two growth patterns of pedunculated or sessile and with or without surface ulceration. This provided useful pretreatment diagnosis of Stage IA disease confined to the endometrium.     

Lymph node metastasis in endometrioid adenocarcinomas of the uterine corpus with occult cervical involvement

Objective

Surgical-pathologic studies have defined the risk of lymphatic metastasis in clinical stage I endometrial cancers. However, data on the risk of lymph node metastasis in endometrial cancers involving the uterine cervix are less robust. The aim of this study was to determine the risk of lymphatic metastasis in patients with endometrial cancers with occult tumor extension to the uterine cervix.

Methods

Our institutional tumor registry identified all patients with endometrioid endometrial cancers who underwent comprehensive surgical staging. Patients with gross involvement of the cervix and patients with extra-uterine disease were excluded. The risk of lymphatic metastasis associated with cervical involvement was analyzed in the context of known uterine risk factors for lymphatic metastasis such as age, depth of invasion, grade, and lymphovascular space invasion (LVSI).

Results

We identified 169 patients who met inclusion and exclusion criteria. Univariate analyses revealed that LVSI (p < 0.01), tumor grade (p < 0.01), depth of myometrial invasion (p < 0.01), tumor free distance (p < 0.01), tumor size (p = 0.02), and cervical involvement (p < 0.01) were associated with lymphatic metastasis while age at diagnosis (p = 0.85) was not. Multivariate analyses revealed that only LVSI (p < 0.01), tumor grade (p = 0.02), and depth of myometrial invasion (p = 0.03) were independently associated with lymphatic metastasis.

Conclusion

Cervical involvement is not an independent predictor of lymphatic metastasis in endometrial cancer. In an unstaged patient, decisions regarding adjuvant treatment or additional diagnostic procedures such as lymphadenectomy should be based on uterine factors.     

Role of lymphadenectomy in endometrioid endometrial cancer

OBJECTIVE: To assess the risk factors associated with node involvement. Study design: In the period 1990-2008 a total of 265 endometrial cancers were treated in the Institut Universitari Dexeus. We analysed the rate of myometrial invasion, tumour grade, histological type and node involvement. RESULTS: Overall, 86% of tumours were endometrioid, 5.3% papillary serous, 4.9% mixed and 2.6% endometrial stroma sarcoma. Among those with endometrioid histology, lymphadenectomy was not performed (NL) in 85 cases (37.2%), whereas pelvic lymphadenectomy (PL) or pelvic and aortic lymphadenectomy (PAL) was carried out in 84 (36.84%) and 59 patients (25.87%), respectively. In NL patients the overall disease-free survival (DFS) rate at five years was 92.8%. In the PL group, node involvement was observed in 2.4% of cases and the five-year DFS rate was 92.3%. Among PAL patients, 18.6% showed node involvement (72.7% positive pelvic nodes and 63.6% aortic). Aortic involvement was present in 5.9% of cases when there was no pelvic disease, whereas in the presence of positive pelvic nodes the rate of aortic involvement was 50%. The DFS rate at five years was 93.6%. Referring to the risk factors, when infiltration was > 50% of the myometrium, lymph node involvement occurred in 37% of cases and G3 tumors in 45.5%. Conclusions: Node involvement is more commonly observed in cases with > 50% myometrial invasion and G3, accounting for 25% of cases that can be considered as at-risk patients. When node involvement is present it is equally distributed between the pelvic and aortic levels. As node involvement is a predictive factor for distant metastasis, the 25% of patients considered to be at risk should undergo pelvic and aortic lymphadenectomy     

Uterine carcinosarcomas and grade 3 endometrioid cancers: evidence for distinct tumor behavior

OBJECTIVE: To compare the clinical behavior and outcome of uterine carcinosarcomas and grade 3 endometrioid carcinomas. METHODS: Data on patients with grade 3 endometrioid adenocarcinomas and uterine carcinosarcomas, from 1988 to 2004, was obtained from the Surveillance, Epidemiology, and End Results database. Mortality was analyzed using Cox proportional hazards models. Survival analysis was performed with the Kaplan-Meier method and log rank test. RESULTS: The cohort included 8,986 women with 5,024 (56%) grade 3 endometrioid carcinomas and 3,962 (44%) uterine carcinosarcomas. Women with uterine carcinosarcomas were older (aged 70 years compared with 66 years; P<.001) and more often nonwhite (23% compared with 15%; P<.001). These women presented with more advanced disease (stage III/IV 41% compared with 31%; P<.001). Multivariable analysis demonstrated that uterine carcinosarcoma histology, advanced age, nonwhite race, and advanced stage were independent predictors of poor survival. Cancer-specific mortality was 45% lower in women with grade 3 endometrioid carcinomas (hazard ratio 0.55; 95% confidence interval [CI] 0.5-0.6). The 5-year cancer-specific survival was lower for women with uterine carcinosarcoma for each disease stage. Survival for stage IC was 38% (95% CI 33-45%) for uterine carcinosarcoma compared with 68% (95% CI 63-73%) for grade 3 endometrioid carcinoma. For stage III, survival was 22% (95% CI 19-26%) for uterine carcinosarcoma compared with 45% (95% CI 41-49%) for grade 3 endometrioid carcinoma. CONCLUSION: Carcinosarcomas present at more advanced stage and have worse survival than grade 3 endometrioid carcinomas. Carcinosarcomas may represent a distinct biologic entity. LEVEL OF EVIDENCE: II.     

Solitary intracranial metastases from primary endometrioid ovarian cancer

A rare case of involvement of the Central Nervous System characterized by brain and subsequent cerebellar metastases without abdomino-pelvic spread is reported. The patient was treated by craniotomy plus external radiation to the brain. Subsequently, Carboplatin-based chemotherapy was started when paraaortic lymph-nodes involvement has been detected. Follow-up is uneventful after clinical complete remission. Received: 17 February 1997 / Accepted: 2 June 1997     

Description of an endometrioid ovarian cancer cell line

A human cell line, designated L-1, has been established from the ascites of an untreated patient with stage IV (FIGO) endometrioid ovarian cancer. This cell line initially grew uninterupted for 6 months without fibroblast contamination and contact inhibition, and has been subcultured weekly for the past 7 years. L-1 does not contain steroid hormone receptors nor does it demonstrate the presence of oncofetal antigens by immunohistochemical techniques. The doubling time of L-1 is 11.8 hr. Flow cytometric analysis reveals an aneuploid DNA peak, and an abnormal karyotype demonstrates hyperdiploidy, translocations, and deletions. Morphology, growth patterns, cytogenetic analysis, and other features of L-1 are characterized.     

Clear cell adenocarcinoma of the endometrium is a biologically distinct entity from endometrioid adenocarcinoma

Clear cell adenocarcinoma (CCA) of the endometrium has a poor prognosis, although the biologic features of this rare tumor are not clear. In this study, we analyzed the expression of biologic markers relating to carcinogenesis, tumor growth, and progression. Thirteen cases of CCA were compared with cases of endometrioid adenocarcinoma (EMA) of the endometrium. Immunohistochemical staining for p53; Ki-67; cyclins A, D1, and E; E-cadherin; progesterone receptor (PR)-A and PR-B; P-glycoprotein; MLH1; and MSH2 was performed. Labeling indices of p53, Ki-67, and cyclins A, D1, and E in CCA were 46.4 +/- 24.3%, 52.1 +/- 20.5%, 37.9 +/- 21.4%, 12.3 +/- 27.9%, and 8.2 +/- 22.9%, respectively. E-cadherin was expressed in only 1 case (7.7%) of CCA, as compared to 39 cases (61.0%) of EMA. No CCAs were positive for PR-A and PR-B. P-glycoprotein was detected in seven cases (53.8%). Loss of either MLH1 or MSH2 expression occurred in eight cases (61.5%). High-level expression of p53, cyclin A, and P-glycoprotein, and low-level or no expression of cyclin E, E-cadherin, PR-A, and PR-B was observed in CCA compared with EMA. The mechanism of cell-cycle regulation in endometrial CCA is different from that in EMA and may influence its malignant potential. Endometrial CCA is a distinct entity from EMA.

Adjuvant treatment for stage IIIC endometrial cancer: options and controversies

Endometrial cancer is the most common gynecologic malignancy. Locally advanced and high risk endometrial cancer encompasses a heterogeneous group of patients and optimal treatment for various sub-groups of these patients remains controversial. Stage IIIC is the most common sub-stage of patients with locally advanced endometrial carcinoma. This article reviews retrospective and prospective data of various adjuvant treatment approaches involving chemotherapy, radiation therapy, or combined modality therapy, including the recently proposed “sandwich” regimens that have yielded encouraging results. Areas of controversy are also discussed to assist clinicians in identifying the most effective adjuvant treatment regimens for patients with locally advanced disease. On-going randomized trials are briefly discussed.     

Hematogenous dissemination in corpus cancer

OBJECTIVE: The aim of this study was to assess the predictors of hematogenous dissemination (HD) in corpus cancer. METHODS: In 612 corpus cancer patients managed surgically, we defined HD as tumor spread to the lung, liver, or other sites via hematogenous routes. RESULTS: We observed 142 instances of tumor spread-71 nonhematogenous and 42 hematogenous to the lung, 9 to the liver, 5 to other sites (adrenals, breast, brain, bone, skin), 3 to both liver and lung, 1 to both lung and bone, and 11 to sites unknown. Stage IV disease, positive adnexae, deep myometrial invasion, primary tumor diameter, tumor involving the whole uterine cavity, positive peritoneal cytology, adjuvant radiotherapy, adjuvant chemotherapy, grade 3 histology, histologic subtype, and lymph-vascular invasion significantly (P < or = 0.01) correlated with HD. However, deep myometrial invasion was the only independent predictor of HD. Only 5% of patients with < or = 50% myometrial invasion had HD compared with 23% with > 50% myometrial invasion. Considering separately recurrence in the lung and in the liver and recurrence in other sites, the only independent predictors of lung recurrence were stage IV disease and myometrial invasion, whereas independent predictors of HD to the liver/other sites were age and histologic grade. Considering only the 60 patients with a known site of HD, 67% with lung recurrence were > 65 years old compared with 17% with HD to the liver/other sites. Furthermore, grade 1-2 disease was observed in 65% of patients with lung recurrence compared with 27% with HD to the liver/other sites. CONCLUSIONS: The presence of deep myometrial invasion was the strongest predictor of HD in corpus cancer, and, together with stage IV disease, it independently predicted lung recurrence. Recurrence in the lung was more frequent in older patients with well or moderately differentiated tumors, whereas HD to the liver/other sites was more frequent in patients < or = 65 years of age harboring grade 3 tumors.     

Stage IIIC Ovarian Leiomyosarcoma in a Premenopausal Woman with Multiple Recurrences: Prolonged Survival with Surgical Therapy

A case of Stage IIIC primary ovarian leiomyosarcoma in a premenopausal woman with multiple recurrences alive and well 7 years after diagnosis is presented. In addition to the typical light microscopic, immunohistochemical, and electron microscopic features of ovarian leiomyosarcoma, the tumor was progesterone receptor positive. This is 28th report of primary ovarian leiomyosarcoma and the first report of progesterone receptor in this tumor. This is the longest reported survival in a woman with this disease.     

Resection of lymph node metastases influences survival in stage IIIC endometrial cancer

OBJECTIVE: Surgical staging of endometrial cancer identifies those patients with microscopic metastatic disease most likely to benefit from adjuvant therapy and may also confer therapeutic benefit. Our objective was to compare survival of patients who underwent resection of grossly positive lymph nodes (LN) to those with microscopically positive LN. METHODS: Patients had stage IIIC endometrial cancer with pelvic and/or aortic LN metastases and underwent surgery between 1973 and 2002. Exclusion criteria included pre-surgical radiation and second primary cancer. Survival was analyzed using Kaplan-Meier method and Cox proportional hazards model. RESULTS: Mean age of 96 patients with stage IIIC endometrial cancer was 64. There were 45 cases with microscopic LN involvement and 51 with grossly enlarged LN. Overall, 41% had disease in aortic LN, which in 18% represented isolated aortic LN metastasis. Adjuvant therapies were given to 92% of patients (85% radiotherapy, 10% chemotherapy, 10% progestins). Among those with grossly involved LN, 86% were completely resected. Five-year disease-specific survival (DSS) was 63% in 45 patients with microscopic metastatic disease compared to 50% in 44 patients with grossly positive LN completely resected and 43% in 7 with residual macroscopic disease. In multivariable analyses, gross nodal disease not debulked (HR=6.85, P=0.009), serosal/adnexal involvement (HR=2.24, P=0.036), diagnosis prior to 1989 (HR=4.33, P<0.001), older age (HR=1.09, P<0.001), and >2 positive lymph nodes (HR=3.12, P=0.007) were associated with lower DSS. CONCLUSION: Grossly involved LN can often be completely resected in patients with stage IIIC endometrial cancer. These retrospective data provide evidence suggestive of a therapeutic benefit for lymphadenectomy in endometrial cancer.
