Oncogene expression: long-term compared with short-term survival in patients with advanced epithelial ovarian cancer.

OBJECTIVE: To determine if oncogene overexpression in patients with advanced epithelial ovarian cancer correlates with survival. METHODS: Twenty-two women with stage III ovarian cancer, observed for a median of 66 (range 48-204) months were compared with 30 with a median survival of 18 (range 2-28) months. Using immunocytochemistry, tumors were immunostained for overexpression of p53, c-erb-B-2, and epidermal growth factor receptor and were evaluated quantitatively for expression of estrogen receptor, progesterone receptor, and Ki-67 antigen, a marker of cellular proliferation. RESULTS: The median age of long-term survivors was 52 (range 30-76) years compared with 55 (range 36-80) years for short-term survivors. Optimal cytoreduction was achieved in 11 of the 22 long-term survivors compared with seven of the 30 short-term survivors, a significant difference (P=.05). The average level of Ki-67 expression was 43% in long-term survivors and 64% in short-term survivors (P=.007). Overexpression of p53 was seen in 54% of long-term survivors and 80% of short-term survivors (P=.05). A combination of Ki-67 level of 50% or greater plus p53 overexpression was seen in 22% of long-term survivors compared with 68% of short-term survivors (P=.005). Epidermal growth factor receptor, c-erb-B-2, estrogen receptor, and progesterone receptor statuses did not differ significantly between the two groups. CONCLUSION: Markers that did not correlate with survival included the hormone receptors, estrogen receptor and progesterone receptor, and the oncogenes, c-erb-B-2 and epidermal growth factor receptor. Long-term survivors with advanced ovarian cancer were more likely to have had an optimal cytoreduction and lower levels of Ki-67 antigen expression and were less likely to overexpress p53 than were short-term survivors.

Serum inhibin and disease status in women with ovarian granulosa cell tumors.

OBJECTIVE: To determine if immunoreactive inhibin assayed in serum from women with granulosa cell tumors correlated with tumor burden, reflected response to treatment, or predicted recurrent disease. STUDY DESIGN: Serum samples were collected following bilateral oophorectomy (BSO) with or without other indicated surgery in 15 patients with granulosa cell tumors. Inhibin radioimmunoassay (RIA-Inh) was performed on all samples and results were correlated with tumor burden, disease status, and treatment response. RESULTS: Fifteen patients had serum assayed for inhibin with levels ranging from 0 to 7470 U/liter. In 4 patients with measurable recurrent disease, inhibin levels correlated directly with tumor burden (r2 = 0.96). Four patients had serum drawn during clinical remission and in all 4 patients elevated inhibin levels predated recurrence by a median interval of 11.5 months (range 7-20). The remaining 7 were treated for primary disease and were in clinical remission with a median follow-up of 33 months (range 9-53). Four of these 7 patients were surgically staged: 2 were FIGO Stage I and inhibin levels fell to 0 U/liter; 2 patients had metastatic disease (Stage IIc and IIIa) and their inhibin levels were found to be elevated following complete resection. The remaining 3 were not surgically staged, and all had elevated inhibin levels while in clinical remission, suggesting occult disease. Of the 15 total patients, 1 who was treated with chemotherapy for recurrent disease was followed with serial inhibin levels. She showed a complete response to therapy with inhibin levels falling from 975 to 0 U/liter with 15 months follow-up. CONCLUSIONS: Serum inhibin levels reflect tumor burden and may be valuable in assessing response to chemotherapy or predicting recurrent disease in women with granulosa cell tumors who have had BSO. Serum inhibin level evaluation should be incorporated into large-group trials of therapy for granulosa cell tumors.

Is Adam worth more than Eve? The financial impact of gender bias in the federal reimbursement of gynecological procedures.

PURPOSE: On January 1, 1992, Congress implemented a Medicare payment system based on relative value units (RVU). The RVU multiplied by a dollar conversion factor sets the reimbursement for all procedures covered by Medicare and many other private insurers. This study was undertaken to evaluate discrepancies in federal reimbursement for gender-specific procedures. METHODS: Using the December 1995 Federal Register and the regional Medicare conversion factor ($40.08/RVU), we compared the work RVU and total reimbursement of 24 groups of gender-specific surgical procedures. The groups were matched as carefully as possible so that the amount of work and level of difficulty would be similar, if not identical. Some examples of comparisons are as follows: biopsy of male vs female genitals, hysterectomy vs prostatectomy, staging for ovarian vs testicular cancer, and exenteration for cervical vs prostate cancer. RESULTS: In the 24 matched procedures, the male-specific procedures were reimbursed at a higher amount in 19 (79%) cases. The female-specific procedures were reimbursed at a higher amount in 3 (12%) cases (P = 0.004). There was no difference in reimbursement for two of the comparisons. Overall, we found that male-specific procedures are reimbursed at an amount which is 44% higher than female-specific procedures. Comparison of work RVU revealed that male-specific procedures were assigned higher values in 19 cases and, overall, male gender-related surgeries had work RVU that were 50% higher than female gender-related surgeries. CONCLUSION: There is significant gender bias against the Medicare reimbursement of female-specific services. This results in a lower net reimbursement for gynecologic procedures. In addition, since many private sector insurance carriers now use the resource-based relative value scale system, this gender bias is further potentiated.

Comparison of 1997 Medicare relative value units for gender-specific procedures: is Adam still worth more than Eve?

BACKGROUND: On January 1, 1992, Congress implemented a Medicare payment system based on relative value units (RVUs). The total RVU (which is made up of work, practice, and malpractice RVUs) is multiplied by a dollar conversion factor to set the reimbursement for all procedures covered by Medicare. In a previous study, we found that significant gender bias exists in Medicare reimbursement for female-specific services. Recently, HCFA approved increases (beginning January 1997) in the work RVU for many gynecologic procedures. This study was undertaken to compare work and total RVUs for gender-specific procedures effective January 1, 1997. METHODS: Using the May 1996 Federal Register, we compared work and total RVUs for 24 pairs of gender-specific procedures. The groups were matched so that the amount of work and level of difficulty would be similar, if not identical. We validated our selection of procedures for comparison by also evaluating the average time required to perform these procedures. RESULTS: Comparison of work RVUs for the 24 paired procedures revealed that in 19 cases (80%), male-specific procedures had a higher RVU; in 3 cases (12%), female-specific procedures were higher; and in 2 cases, there was no difference. On average, work RVUs were 49% higher for urologic procedures than for gynecologic procedures. Comparison of total RVUs revealed that in 20 cases (83%), urologic procedures had a higher total RVU and in 3 cases (12%), gynecologic procedures were higher. On average, male-specific surgeries are reimbursed at an amount which is 37% higher than that for female-specific surgeries. CONCLUSION: Recent increases in work RVUs for many gynecologic procedures have resulted in improved reimbursement. However, even with these improvements, significant gender bias still exists in the Medicare reimbursement of female-specific procedures. This gender bias is further magnified as more private insurance carriers use the system to set reimbursement.

A retrospective review of paclitaxel-associated gastrointestinal necrosis in patients with epithelial ovarian cancer.

Seven patients with gastrointestinal necrosis following paclitaxel chemotherapy are reported. Four of seven patients had platinum refractory disease, while 3/7 patients received primary paclitaxel therapy. Complications occurred 5 to 16 days following paclitaxel therapy. The most common clinical presentation was fever (7/7 patients), neutropenia (6/7 patients), and abdominal pain (6/7 patients). All seven patients developed gastrointestinal necrosis following the first cycle of paclitaxel chemotherapy. The exact mechanism by which this complication occurs is poorly understood. We postulate that gastrointestinal necrosis may be the result of a direct drug effect on the gastrointestinal epithelium and might involve a synergistic interaction between compromised bowel and paclitaxel-induced mitotic arrest. We observe that the incidence of gastrointestinal necrosis in patients with platinum refractory disease is 4 of 108 patients (3.7%). The incidence of this complication in patients receiving primary paclitaxel at our institution is 3 of approximately 128 patients (2.3%). Eighteen cases to date have been identified in the literature. A high index of suspicion of this complication should be considered for patients presenting with neutropenic fever and abdominal pain following paclitaxel chemotherapy.

The expression of epidermal growth factor receptor, HER-2/Neu, p53, and Ki-67 antigen in uterine malignant mixed mesodermal tumors and adenosarcoma.

Uterine malignant mixed mesodermal tumors (MMMT) are highly malignant tumors containing both malignant glands and stroma, while adenosarcomas (AS) are less aggressive tumors composed of malignant stroma and benign glands. Immunohistochemistry was used to grade overexpression of p53 protein, HER-2/neu protein, epidermal growth factor receptor (EGFR), and Ki-67 antigen in both the glands and stroma of tissue from 20 women with MMMT and 6 women with AS. EGFR was overexpressed in 2 AS and 9 MMMT, and was more commonly found in the sarcomatous component than the carcinomatous component in MMMT (P = 0.03). p53 was not found in any AS samples and was strongly present in 6 MMMT samples with a random distribution between the malignant components. HER-2/neu protein was not overexpressed in any AS or primary MMMT. Ki-67 antigen, a marker of cell proliferation, was found at higher levels in MMMT than AS samples (P = 0.03) and high Ki-67 antigen expression correlated with a decreased survival in patients with MMMT (P = 0.004). Independent characterization of oncogene proteins in the malignant components of these heterogeneous tumors may provide insight into the histogenesis and behavior of these malignancies.

Histologic transformation of benign endometriosis to early epithelial ovarian cancer.

Between 1975 and 1990, 79 patients with Stage I epithelial ovarian cancer were treated at Massachusetts General Hospital. Patients were identified from the tumor registry and medical records were retrospectively reviewed. Pathological slides were evaluated for the presence of endometriosis, specifically looking for malignancy arising in endometriosis. Evidence of endometriosis was found in 22 of the 79 cases (28%). In the 23 cases of endometrioid histology, 9 cases (39%) were associated with endometriosis and, in the 17 cases of clear cell tumors, 7 (41%) were associated with endometriosis. All 8 cases of mixed histology had clear cell and/or endometrioid components and 4 cases (50%) were associated with endometriosis. Endometrioid adenocarcinoma accounted for 41% of the tumors associated with endometriosis, clear cell carcinoma 31%, mixed (endometrioid and/or clear cell types) 18%, and other types 9%. Among the 22 patients with associated endometriosis, we found 7 carcinomas (32%) arising in endometriosis. In these 7 cases a spectrum of benign and atypical endometriosis with a transition to clear cell or endometrioid adenocarcinoma were identified. These premalignant changes were characterized by cytologic atypia and architectural proliferation. Endometriosis was frequently encountered among patients with Stage I epithelial ovarian cancer of endometrioid and clear cell histologies. Endometriosis may play a role in the pathogenesis of some early stage malignant ovarian epithelial neoplasms.

Clear cell carcinoma of the ovary: a distinct histologic type with poor prognosis and resistance to platinum-based chemotherapy in stage III disease.

Between 1982 and 1992, 24 women with Stage III clear cell ovarian cancer were identified from the tumor registry. Thirty-four women with Stage III papillary serous tumors treated between 1987 and 1989 were used as a comparison. All patients underwent cytoreductive surgery followed by conventional platinum-based chemotherapy. In the women with clear cell histology, nine (37.5%) had endometriosis in the surgical specimen compared with one (3%) in the papillary serous group (P = 0.002). Ten women (42%) with clear cell histology experienced a thromboembolic event during the course of treatment, compared to six (18%) in the papillary serous group (P = 0.05). In the group with clear cell histology, overall, 70% of women had progressive disease. Fifty-two percent experienced clinical progression while receiving platinum-based chemotherapy. In addition, four patients were found to have progressive disease at second-look laparotomy. Only two patients had a pathologic complete response. In the group with papillary serous histology, 29% overall had progressive disease while on chemotherapy (P = 0.005). The median survival for the women with clear cell histology was 12 months compared to 22 months for those with papillary serous (P = 0.02). For women with clear cell histology, univariate analysis was used to evaluate prognostic factors. Age less than 50 was a poor prognostic factor (P = 0.045). The presence of endometriosis, thromboembolic event, or optimal cytoreduction were not prognostic factors (P = 0.67, P = 0.34, P = 0.39). Patients with advanced clear cell ovarian cancer have a poor response to conventional platinum-based chemotherapy and overall prognosis is poor.

Expanded pelvic radiotherapy fields for treatment of local-regionally advanced carcinoma of the cervix: outcome and complications.

OBJECTIVE: Recent anatomic and radiographic studies have indicated that standard external beam radiation portals may not adequately treat the volume at risk in patients with local-regionally advanced cervical cancer. A feasibility study was undertaken to evaluate toxicity, outcome, and patterns of failure in patients with advanced cervical cancer treated by expanded pelvic radiation fields. STUDY DESIGN: Thirty-eight women with stages IIB and III cancers of the cervix confined to the pelvis were irradiated with curative intent with expanded pelvic radiation portals. Anteriorly and posteriorly, the median field length and width were 20 and 17.5 cm, respectively. Lateral fields had a median width of 16.5 cm, and the posterior border encompassed the entire sacral silhouette. The median external beam whole-pelvis dose was 4140 cGy, with overall point A dose boosted by brachytherapy to 8315 cGy. RESULTS: Stage IIB patients (n = 22) had a 4-year actuarial local control rate of 70%, freedom from distant metastases rate of 62%, and disease-specific survival rate of 76%. In stage III disease (n = 16), the 4-year actuarial local control, freedom from distant metastases, and disease-specific survival rates were 80%, 48%, and 53%, respectively. Radiographically determined nodal status was an important predictor of disease-specific survival and distant metastases but not local control. The 4-year disease-specific survival rate was 40% in 11 patients with nodal disease compared with 71% in 27 node-negative patients (p < 0.01). The rate of freedom from distant metastases was 36% in node-positive patients versus 67% in node-negative cases (p < 0.01). The actuarial overall 4-year severe late complication rate was 14.8%. CONCLUSION: This study has demonstrated that expanded fields for pelvic radiotherapy is feasible, well tolerated, and therapeutic. The pelvic field design concepts presented should be integrated into radiation oncology practice.

Treatment of ovarian cancer with photodynamic therapy and immunoconjugates in a murine ovarian cancer model.

In photodynamic therapy (PDT), photosensitisers accumulate somewhat preferentially in malignant tissues; photoactivation with appropriate wavelength of light release toxic molecular species which lead to tumour tissue death. In order to target ovarian cancer with increased specificity, a chlorin-based photosensitiser (chlorin e6 monoethylendiamine monoamide) was conjugated to OC125, a monoclonal antibody recognising an antigen expressed in 80% of non-mucinous ovarian cancers. In previous work, this immunoconjugate (IC) was shown to be selectively phototoxic to cancer cells from ovarian cancer patients ex vivo and to localise preferentially in ovarian cancer tissue in vivo. In this study we report results from in vivo phototoxicology and photodynamic treatment studies using this IC in a murine model for ovarian cancer. A comparison of single vs multiple treatments was also made. For in vivo experimentation, Balb C nude mice were injected with 30 x 10(6) NIH:OVCAR 3 cancer cells to create an ascitic tumour model. Animals were then given intraperitoneal injections of the immunoconjugate (0.5 mg kg-1). Twenty-four hours later the intraperitoneal surfaces were exposed to 656 nm light from an argon-ion pumped-dye laser (50 mW, 656 nm), using a cylindrical diffusing tip fibre. The overall treatment was given either once or multiply. No animals died from treatment complications. Twenty-four hours following one and three PDT treatments, the percentage of viable tumour cells in the ascites of the treated animals analysed ex vivo was 34% and 5% of control for one and three treatments respectively. With respect to survival, all control mice (n = 18) died between 30 and 50 days. However, for those treated three times (n = 10), 40% were still alive after 50 days, and for those treated four times (n = 12) 58% were alive after 50 days. Evaluation with log-rank test revealed a significant survival with intraperitoneal PDT compared with controls (P = 0.0006). These preliminary results suggest that PDT with an OC125 immunoconjugate may be an effective therapy for the management of advanced ovarian cancer. Clinical application of this therapy needs to be further optimised and may require multiple treatments, similar to fractionated radiation therapy and cyclic chemotherapy, in order to control malignant disease with acceptable toxicity to normal tissue.

Postoperative management of patients with stage Ib endometrial carcinoma.

Between 1980 and 1990, 124 patients with Stage Ib endometrioid adenocarcinoma of the endometrium were treated at Massachusetts General Hospital (MGH). Patients were identified from the tumor registry and medical records were retrospectively reviewed. Of the 124 patients, four (3%) developed a recurrence. Eighty-six patients had grade 1 tumors, 32 grade 2 and 6 grade 3. Recurrences developed in two (2%) of the grade 1 tumors, one (3%) of the grade 2, and one (17%) of the grade 3. Of the 86 patients with grade 1 carcinomas, 58 received no adjuvant radiation, 25 received vaginal vault brachytherapy and 3 whole pelvic radiation (WPR). Of the 32 patients with grade 2 tumors, 13 received no adjuvant therapy, 10 vaginal brachytherapy, and 9 WPR. Of the six patients with grade 3 tumors, one received no adjuvant therapy, two vaginal brachytherapy, and three WPR. Of the four women that relapsed, only the patient with grade 3 tumor had been treated with adjuvant radiation (WPR). Three of the four patients recurred at the vaginal vault and all three were salvaged. Stage Ib, grade 1 and 2, endometrioid adenocarcinomas have a good prognosis and adjuvant radiotherapy is not clearly beneficial.

Overexpression and relationships of HER-2/neu, epidermal growth factor receptor, p53, Ki-67, and tumor necrosis factor alpha in epithelial ovarian cancer.

OBJECTIVE: To determine the frequency and possible relationships of overexpression of oncogenes, cytokines, and cellular proliferation proteins in ovarian cancer. METHODS: Sixty-four epithelial ovarian cancer specimens were obtained from the GOG tumor bank. Using immunocytochemistry, tumors were stained for overexpression of HER-2/neu, epidermal growth factor receptor (EGFR), p53, tumor necrosis factor alpha (TNF alpha), and Ki-67 (a marker of cellular proliferation). RESULTS: Twenty-one tumors were Stage I/II and 43 were Stage III/IV. HER-2/neu was overexpressed in 7 cases (11%), EGFR in 12 cases (19%), and p53 in 32 cases (50%). Ki-67 was expressed in all but one case, and high indices (expression in over 50% of cells) were seen in 18 cases (28%). TNF alpha was expressed in all but one case. Comparison between Stage I/II and Stage III/IV cases revealed no difference in the expression of these oncoproteins. Comparison by histologic grade also revealed no difference in the expression of the oncoproteins, except for EGFR, which was overexpressed only in Grade 3 tumors (p = 0.01). Comparison between tumors that did or did not overexpress p53 revealed insignificant differences in the expression of HER-2/neu, EGFR and TNF alpha. In addition there were no differences with respect to stage, grade, or histology when tumors where analyzed with respect to p53 overexpression. There was a trend towards an association between p53 overexpression and high levels of Ki-67 (p = 0.10). Comparison of tumors with high Ki-67 indices to those with lower indices also revealed no association with the expression of HER-2/neu, or EGFR, and there were no differences in stage or grade distribution. CONCLUSION: Ki-67 and p53 were frequently overexpressed in this representative sample of ovarian cancers from the GOG tumor bank; however, their expression was not associated with stage, grade, histology, or overexpression of other oncoproteins. Lack of a recognizable pattern of oncogene overexpression emphasizes the underlying biologic complexity of ovarian cancer.

Malignant mixed müllerian tumors of the ovary: experience with surgical cytoreduction and combination chemotherapy.

BACKGROUND: The role of surgical cytoreduction and combination chemotherapy for malignant mixed müllerian tumors (MMMT) of the ovary was evaluated. METHODS: A retrospective review of 27 women with ovarian MMMT treated from 1980 to 1990 was performed. RESULTS: The International Federation of Gynecology and Obstetrics stages for the 27 women were 1 Stage I, 3 Stage II, 17 Stage III, and 6 Stage IV. Only 10 of the 23 patients with Stage III or IV disease were cytoreduced optimally. With respect to postoperative therapy, 3 women received no treatment, 6 were treated with whole abdomen radiotherapy, 1 received melphalan, and 17 received chemotherapy incorporating a platinum agent (3), doxorubicin (4), or both (10). The significant prognostic factors were stage (P < 0.001) and, for women with Stage III or IV disease, the feasibility of cytoreductive surgery (P = 0.03). The four patients in Stages I or II remained disease free after an interval of at least 5 years. The median and 5-year survival rates for patients with Stages III or IV disease was 18 months and 8%, respectively. Patients in Stage III or IV for whom optimal cytoreduction was not possible had a 2-year survival of 14%, whereas optimal cytoreduction was associated with a 52% 2-year survival. Median survival for the 14 women with Stage III or IV ovarian MMMT treated with combination chemotherapy was 25 months and nine women achieved progression free intervals of greater than 18 months. CONCLUSIONS: Aggressive surgical cytoreduction followed by combination chemotherapy may result in improved progression free intervals for women with advanced ovarian MMMT. However, a major improvement in prognosis for this rare malignancy has not yet been achieved.

Uterine papillary serous carcinoma (UPSC): a clinicopathologic study of 30 cases.

Between 1975 and 1989, 896 patients were treated for endometrial carcinoma at the Massachusetts General Hospital. Thirty patients were identified from the tumor registry as having uterine papillary serous carcinomas. The survival for all patients and for groups of patients stratified on clinical and pathological parameters was examined in the Kaplan-Meier survival curves. Curves for the different strata were compared using the logrank test. The 5-year survival for the 30 patients was 30% +/- 9%. Patients with surgical stage I and II tumors had a 5-year survival rate of 79% +/- 14% compared to 25% +/- 10% in patients with stage III and IV tumors (P = 0.02). Clinical stage, depth of myometrial invasion, lymph-vascular space invasion, tumor grade, and DNA aneuploidy were not found to significantly impact on survival. However, a survival advantage was seen in patients diagnosed with early surgical stage tumors, reinforcing the need for thorough staging at the time of laparotomy.

The use of intraoperative radiation therapy in radical salvage for recurrent cervical cancer: outcome and toxicity.

OBJECTIVE: Our purpose was to evaluate the contribution of intraoperative radiation therapy in the management of recurrent cervical cancer. STUDY DESIGN: Twenty-two patients were treated with electron beam intraoperative radiation therapy for recurrent cervical cancers that were confined to the pelvis but were too extensive to be adequately treated by radical surgery alone. All patients underwent extensive surgical dissection for exposure and maximal tumor resection. Doses of intraoperative radiation therapy ranged from 14 to 27.8 Gy (median 22 Gy). Twelve patients received intraoperative radiation therapy to address gross residual disease, and 10 patients were treated for microscopically positive or close surgical margins. RESULTS: The five-year disease-specific survival and local control rates were 43% and 48%, respectively. There were trends toward better local control and disease-specific survival in patients with microscopic residual disease compared with those with gross residual disease. Seven patients had peripheral neuropathy related to treatment, and four of these cases resolved. CONCLUSION: In carefully selected cases intraoperative radiation therapy contributes to radical salvage of patients with recurrent cervical cancer involving the pelvic wall.

Clinicopathologic variables, operative characteristics, and DNA ploidy in predicting outcome in ovarian epithelial carcinoma.

OBJECTIVE: To test the hypothesis that DNA content can predict operative morbidity and survival in patients with ovarian carcinoma. METHODS: Subjects included patients diagnosed with invasive epithelial ovarian carcinoma at Brigham and Women's Hospital between July 1987 and November 1989. Fifty-nine patients were included in this analysis. In all cases, flow cytometry was performed on fresh tissue to evaluate DNA content. The medical records were reviewed in all patients for estimated blood loss, hospitalization days, intensive care unit days, operating room time, presence and size of residual disease, grade and type of tumor, stage, size of primary tumor, lymph node status, disease status, date of last examination, and number of months of follow-up. RESULTS: Predictors for death included increasing age (P = .01), advanced stage (P = .007), the presence of malignant ascites (P = .03), residual tumor at completion of operation (P < .001), increased estimated blood loss (P < .001), increased hospitalization days (P < .001), and increased operating room hours (P < .001). When we controlled for age and stage, only estimated blood loss and residual tumor predicted poor outcome. Deoxyribonucleic acid ploidy, whether stratified as diploid or aneuploid or with DNA index cutoffs, did not predict tumor recurrence or survival rates. CONCLUSION: Deoxyribonucleic acid ploidy has not yet been proven to be of independent prognostic importance for identifying groups of patients at high risk of dying from invasive epithelial ovarian carcinoma.

Surgical stage IV endometrial carcinoma: a study of 47 cases.

Between 1976 and 1991, 47 patients with surgical Stage IV endometrial carcinoma were treated. Patients were identified from the tumor registry and charts were retrospectively reviewed. Surgical curves using the Kaplan-Meier product-limit method and Cox regression analysis were used to identify independent prognostic factors. Overall, median survival was only 12 months. Using univariate analysis there was no statistically significant difference in survival between age (P = 0.41), histology (P = 0.54), grade (P = 0.91), disease site (P = 0.32), or clinical stage (P = 0.87). In patients whose disease was surgically cytoreduced, the median survival was 18 months compared to 8 months in those who did not undergo surgery (P = 0.0001). Evaluation of other treatment modalities by univariate analysis revealed improved survival in those patients who received cyclophosphamide, doxorubicin, and cisplatin (P = 0.0007), decreased survival in those who received radiation therapy compared to surgery (P = 0.023), and no statistically significant difference in survival with progestins. By multivariate analysis successful cytoreduction was the only statistically significant prognostic variable (P = 0.04). This 15-year retrospective review confirms that prognosis for women with Stage IV endometrial cancer is extremely poor. However, if hysterectomy with cytoreduction is feasible, surgery should be performed because survival may be improved.
