Pregnancy-associated Breast Cancer.

Breast cancer is one of the most common malignancies affecting pregnancy. Pregnancy-associated breast cancer refers to breast cancer that is diagnosed during pregnancy or within the first postpartum year. The incidence is increasing as more women delay childbearing. Breast cancer can be safely diagnosed, staged, and treated during pregnancy while protecting the fetus and mother with excellent outcomes for both. Avoiding diagnostic delays is vital to prognosis. This article provides an overview of the diagnosis, staging, management, and prognosis of pregnancy-associated breast cancer. Relevant current literature is reviewed.

Multicenter phase II trial of topotecan, cisplatin and bevacizumab for recurrent or persistent cervical cancer.

OBJECTIVE: We evaluated the activity and safety of the combination of topotecan, cisplatin and bevacizumab in patients with recurrent or persistent carcinoma of the cervix. METHODS: Eligible patients had persistent or recurrent cervical cancer not amenable to curative intent treatment. No prior chemotherapy for recurrence was allowed. Treatment consisted of cisplatin 50 mg/m(2) day 1, topotecan 0.75 mg/m(2) days 1, 2 and 3 and bevacizumab 15 mg/kgday 1 every 21 days until disease progression or limiting toxicity. The primary endpoint was progression free survival at 6 months. We explored PET/CT as a potential early indicator of response to therapy. RESULTS: Twenty-seven eligible patients received a median of 3 treatment cycles (range, 1-19). Median follow-up was 10 months (range, 1.7-33.4). The 6-month PFS was 59% (80% CI: 46-70%). In 26 evaluable patients, we observed 1 CR (4%; 80% CI: 0.4-14%) and 8 PR (31%; 80% CI: 19-45%) lasting a median of 4.4 months. Ten patients had SD (39%; 80% CI: 25-53%) with median duration of 2.2 months. Median PFS was 7.1 months (80% CI: 4.7-10.1) and median OS was 13.2 months (80% CI: 8.0-15.4). All patients were evaluated for toxicity. Grade 3-4 hematologic toxicity was common (thrombocytopenia 82% leukopenia 74%, anemia 63%, neutropenia 56%). Most patients (78%) required unanticipated hospital admissions for supportive care and/or management of toxicities. CONCLUSION: The addition of bevacizumab to topotecan and cisplatin results in an active but highly toxic regimen. Future efforts should focus on identification of predictive biomarkers of prolonged response and regimen modifications to minimize toxicity.

Clinical and pathologic features of vulvar intraepithelial neoplasia in premenopausal and postmenopausal women.

OBJECTIVE: To explore the clinical and pathologic differences between vulvar intraepithelial neoplasia (VIN) in premenopausal and postmenopausal women cared for in a tertiary referral center. METHODS: Between January 1997 and June 2008, 145 women received care at our institution for VIN and VIN-associated squamous cell carcinoma (SCC). All patients' demographic characteristics and recurrence histories were recorded throughout the study period and were retrieved retrospectively. Menopausal status was self-reported at the time of initial diagnosis. χ, odds ratio, and logistic regression analyses were used. RESULTS: The median age was 50 years (range = 19-91 y) with 77% (111/145) of patients white, 20% (29/145) African American, and 3% (5/145) other ethnicity. Sixty percent of patients diagnosed with VIN were current smokers, 18% (26/145) were immunocompromised (positive for human immunodeficiency virus/transplant/steroids), and 30% (44/145) had concomitant or previous lower genital tract dysplasia. Vulvar intraepithelial neoplasia or VIN-related cancer recurred in 57 (39%) of 145 patients; of these, 40 (71%) had recurrence of VIN and 18 (29%) had recurrence of cancer. Fifty-one percent (74/145) of patients were menopausal at initial VIN diagnosis. Among women with VIN, the odds of initially presenting with a VIN-related SCC was 3.2 times greater in postmenopausal than in premenopausal women (confidence interval = 1.5-7.1, p < .01), and postmenopausal women were more likely to present with stage II to IV SCC (p = .021). Recurrence risk of SCC, but not VIN, was associated with menopause status (p < .05). CONCLUSIONS: Among women with VIN, the risk of SCC is higher in postmenopausal than in premenopausal women both initially and at recurrence. Excisional therapies to identify occult invasion are especially important for postmenopausal women with VIN.

Chemoradiation in locally advanced cervical carcinoma: an analysis of cisplatin dosing and other clinical prognostic factors.

OBJECTIVES: The aim of this study was to evaluate the effect of number of chemotherapy cycles and other clinical and pathologic factors on progression-free (PFS) and overall survival (OS) in patients with newly diagnosed cervical cancer. METHODS: We identified 118 patients with locally advanced cervical cancer (stages IB2-IVA) treated with combination weekly cisplatin (40 mg/m(2)) and radiation therapy (RT) between 2003 and 2007. Kaplan-Meier and Cox proportional hazard models were utilized to evaluate PFS and OS for associations with number of chemotherapy cycles and other factors. RESULTS: The majority of patients had stage IB2 or II disease (70%), squamous histology (91%), and size <6 cm (65%). Median RT duration was 50 days and 95% received brachytherapy. Thirty percent of patients completed <6 cycles of chemotherapy, and estimated PFS and OS were 63% and 75%, respectively. In multivariate analyses, the number of chemotherapy cycles was independently predictive of PFS and OS. Patients who received <6 cycles of cisplatin had a worse PFS (HR 2.65; 95% CI 1.35-5.17; p=0.0045) and OS (HR 4.47; 95% CI 1.83-10.9; p=0.001). Advanced stage, longer time to RT completion, and absence of brachytherapy were also associated with decreased OS and PFS (p<0.05). Similar results were found when analysis was conducted using a breakpoint of at least five but not less than five chemotherapy cycles. Higher grade was associated with decreased PFS (p=0.03) but not OS. Age, race, BMI, tumor size, smoking, histology, and IMRT were not statistically significant for OS or PFS. CONCLUSIONS: Aggressive supportive care to minimize missed chemotherapy treatments may improve survival after chemoradiation.

"Surgical Apgar Score" predicts postoperative complications after cytoreduction for advanced ovarian cancer.

OBJECTIVE: A 10-point "Surgical Apgar Score" (SAS) for predicting postoperative complications after general and vascular operations has recently been developed and validated. We sought to estimate the ability of this metric to predict major postoperative complications in women undergoing ovarian cancer cytoreductive procedures. METHODS: All eligible patients with stage III and IV epithelial ovarian, fallopian tube and primary peritoneal cancer undergoing surgical cytoreduction at our institution between 1999 and 2005 were included. Medical records were reviewed and demographic data, clinicopathologic characteristics, comorbidities and intra and postoperative complications were analyzed. The surgical score was calculated from intraoperative blood loss, lowest mean arterial pressure and lowest heart rate as previously described. Descriptive statistics, univariable and multivariable analyses were used as appropriate. Occurrence of major postoperative complications represented the primary outcome. RESULTS: A total of 232 cases were analyzed. Mean age was 62 years. Most patients were Caucasian (92%) and diagnosed with stage III disease (83%). Mean duration of surgical procedure was 171 (70-350) minutes. Median SAS was 6 points (range 1-9). On multivariable analyses, occurrence of major postoperative complications was associated with multiple comorbidities (OR 2.2; 95% CI:1.5-3.1; p<0.0001), stage IV disease (OR 2.5; 95% CI:1.1-5.7; p=0.03), ASA class (OR 2.4; 95% CI:1.2-4.7; p=0.01) and SAS

The role of PET/CT in the management of patients with cervical cancer: practice patterns of the members of the Society of Gynecologic Oncologists.

OBJECTIVES: Recent data has highlighted the role of PET/CT in the pretreatment evaluation and follow-up of patients with cervical cancer. The objective of our study was to assess the acceptance of PET/CT into the management of patients with cervical cancer. We also explored potential barriers to the use of these imaging modalities in patients with cervical cancer. METHODS: A 14-item electronic questionnaire was initially sent to all working addresses of members of the SGO (n=1048). An opt-out option was offered. For members who did not respond within 3 weeks, a second electronic invitation was sent. A third request was finally sent to further improve response rates. Data were collected and analyzed using a commercially available on-line survey database. RESULTS: A total of 305 responses were collected for an overall 30% response rate. PET/CT appears to be widely available (99%) and accessible (75%) in most practices. Although 83% of members order routine CT imaging for all newly diagnosed cervical cancer cases, only 28% routinely order a PET/CT. Conversely, 64% would order a PET/CT for newly diagnosed patients with advanced disease or those at high risk for distant metastatic disease. Most members (82%) do not routinely use PET/CT to assess response to treatment. Twenty percent of members believe that no useful prognostic information can be obtained from routine use of molecular imaging in patients with cervical cancer. The most common barriers for use of PET/CT cited by members were perceived lack of third-party payer coverage and lack of scientific evidence. CONCLUSIONS: Despite clear scientific data supporting the use of PET/CT in patients with cervical cancer and apparent widespread availability, this imaging modality remains highly underutilized in clinical practice. Clarifying insurance coverage early in the evaluation process and replicating studies that have shown effectiveness of PET/CT in multiple roles may improve adoption of this potentially useful imaging modality.

The value of perioperative imaging in patients with uterine sarcomas.

OBJECTIVE: To explore the yield and impact of perioperative imaging on management among patients undergoing surgical resection and treatment of uterine sarcomas. METHODS: A retrospective chart review was done for women with histologically confirmed uterine sarcomas treated at Barnes Jewish Hospital/Washington University from 2001 to 2007. Descriptive statistics, Cox multivariate models, and Kaplan-Meier plots were used to evaluate associations and survival. RESULTS: A total of 92 patients were identified and 55 (60%) were diagnosed with stage III-IV disease. Perioperative imaging was obtained in 84 (91%) cases, including chest X-ray in 66 (72%), computerized tomography (CT) of the abdomen and pelvis in 59 (64%), chest CT in 33 (36%), positron emission tomography (PET) in 8 (9%), and CT of the head, pelvic magnetic resonance imaging (MRI), or bone scan in a total of 2 (2.2%). Imaging identified abnormalities concerning for metastases in 30 (32%) studies. Thirty-four recurrences have been documented, and 21 (62%) of these treatment failures were extrapelvic. Multivariate analysis of this series noted that tomographic evidence of extrauterine disease predicted recurrence (p=0.028) and incomplete surgical resection (p=0.003, HR 6.0 95% CI 1.9-19.9) predicted disease-free survival. Imaging contributed to change in surgical and post-surgical treatment decisions in 8 (9%) patients. CONCLUSION: Pretreatment imaging studies change management in a minority of patients with newly diagnosed uterine sarcomas.

Clustering of Lynch syndrome malignancies with no evidence for a role of DNA mismatch repair.

OBJECTIVES: We ascertained a large kindred with an excess of Lynch syndrome-associated cancers. Our objective was to determine if a defect in one of the DNA mismatch repair (DMMR) genes was the probable cause of cancer susceptibility as microsatellite instability (MSI) and immunohistochemical (IHC) analysis of the probands' tumors did not provide a clear indication. METHODS: A detailed history and review of medical records was undertaken to construct a four-generation pedigree. Blood samples were obtained for analysis of germline DNA. Polymorphic repeats from the MLH1, MSH2, MSH6, and PMS2 loci were genotyped and the co-segregation of markers and disease was assessed. DMMR gene expression for all available tumors was evaluated by IHC. Combined bisulfite restriction analysis (COBRA) of MLH1 was utilized to test for germline epimutation. RESULTS: Four gynecologic carcinomas, 3 colon carcinomas, and 13 cases of adenomatous polyps were identified. The family met Amsterdam II criteria. The mean age of cancer diagnosis in the kindred was 63 years (range 44-82 years). DNA marker analyses excluded linkage to MLH1, MSH2, MSH6, and PMS2. Furthermore, MSI and IHC analysis of tumors did not suggest a role for DMMR. Methylation of the MLH1 promoter was identified in the peripheral blood leukocytes (PBLs) of a family member with an early onset colon cancer. CONCLUSIONS: We identified a large family with multiple Lynch malignancies and no evidence for an inherited defect in DMMR. This family represents an important but poorly understood form of autosomal dominant inherited cancer susceptibility. Aberrant MLH1 promoter methylation in normal tissues may be a marker for cancer susceptibility in families such as this.

Cervical intraepithelial neoplasia in adolescent women: incidence and treatment outcomes.

OBJECTIVE: We sought to estimate the incidence of cervical intraepithelial neoplasia (CIN) and treatment outcomes in adolescents with abnormal cytology. METHODS: Adolescent women (ages 14-21 years) referred to colposcopy clinic for abnormal cytology from 1992 to 2004 were identified by computerized database. Only adolescents with biopsy-proven CIN were evaluated. Demographic and risk factor data were obtained from medical records. Referral cytology, histology on biopsy and loop electrosurgical excisional procedure (LEEP), and follow-up cytology were analyzed and compared. Statistical analysis was performed by chi(2) or Fisher exact test, Student t tests, and logistic regression. RESULTS: Of 1,678 adolescents, 517 had biopsy-proven CIN and follow-up. Seventy-seven patients were referred with atypical squamous cells of undetermined significance (ASCUS) cytology; 174 patients were referred with low-grade squamous intraepithelial lesions (LSIL), 258 with high-grade squamous intraepithelial lesions (HSIL) and eight with atypical glandular cells (AGC). The rate of CIN 2/3 in patients with ASCUS, LSIL, and HSIL was 35% (95% confidence interval 24-46%), 36% (29-43%), and 50% (44-56%), respectively. A total of 192 patients with biopsy-proven CIN 2/3 underwent a LEEP. No patients were diagnosed with cervical carcinoma. Fifty-five percent (95% confidence interval 48-62%) of patients had abnormal cytology on follow-up, suggesting recurrence or reinfection. CONCLUSION: Adolescents with abnormal cytology have a high incidence of CIN2/3 and high rates of abnormal cytology after LEEP. Cervical intraepithelial neoplasia 2/3 is common in adolescents with abnormal cytology, yet no cases of cancer were identified. Importantly, LEEP fails to meet its therapeutic goals given a high incidence of abnormal follow-up cytology and may represent overly aggressive therapy because the majority of human papillomavirus infections are transient with high regression rates. LEVEL OF EVIDENCE: III.

A prospective blinded evaluation of the accuracy of frozen section for the surgical management of endometrial cancer.

OBJECTIVE: To prospectively evaluate in a blinded fashion the accuracy of frozen section in endometrial cancer. METHODS: Sixty patients with endometrial cancer or complex atypical hyperplasia were consecutively enrolled. Intraoperatively, a frozen section was obtained, processed, and stored for interpretation by blinded pathologists. Final pathologic diagnosis was conducted in the usual fashion with the pathologists blinded to frozen results. Histologic grade and myometrial invasion on frozen section was correlated with final pathology. RESULTS: Median age was 61 years (range, 39-82 years). Fifty-seven percent of patients were white, and mean body mass index was 40 mg/kg2. Depth of invasion on frozen correlated with final pathology in 67% (95% confidence interval [CI] 55-79%). Twenty-eight percent (95% CI 17-39%) of patients were upstaged from frozen to final. Patients with no invasion on frozen were upstaged in 46% (95% CI 28-64%). Histologic grade on frozen correlated with final pathology in 58% (95% CI 46-70%); 38% (95% CI 26-50%) of patients were upgraded by final grade. Patients with frozen grade 1 histology or less were upgraded in 61% (95% CI 45-77%). Clinically relevant upstaging occurred in 11 patients (18%) (95% CI 8-28%). CONCLUSION: Frozen section for histologic grade and depth of myometrial invasion in endometrial cancer correlates poorly with final pathology. Because a large number of patients are potentially understaged with the use of frozen section with a subsequent risk of over and under treatment, we recommend consideration of comprehensive surgical staging for all patients with endometrial cancer. LEVEL OF EVIDENCE: II-2.

Misoprostol for labor induction in women with term premature rupture of membranes: a meta-analysis.

OBJECTIVE: To systematically review published data evaluating the comparative use of misoprostol with placebo/expectant management or oxytocin for labor induction in women with term (> or = 36 weeks of gestation) premature rupture of membranes. DATA SOURCES: PubMed (1966-2005), Ovid (1966-2005), CINAHL, The Cochrane Library, ACP Journal Club, OCLC, abstracts from scientific forums, and bibliographies of published articles were searched using the following keywords: premature rupture of membranes, misoprostol, labor induction, and cervical ripening. Primary authors were contacted directly if the data sought were unavailable or only published in abstract form. METHODS OF STUDY SELECTION: Only randomized controlled trials evaluating the efficacy and safety of misoprostol in comparison with placebo or expectant management (n = 6) and oxytocin (n = 9) published in either article or abstract form were analyzed and included in the meta-analysis. TABULATION, INTEGRATION, AND RESULTS: Studies were reviewed independently by all authors. Meta-analysis was performed, and the relative risks (RRs) were calculated and pooled for each study outcome. Misoprostol, compared with placebo, significantly increased vaginal delivery less than 12 hours (RR 2.71, 95% confidence interval [CI] 1.87-3.92, P < .001). Misoprostol was similar to oxytocin with respect to vaginal delivery less than 24 hours (RR 1.07, 95% CI 0.88-1.31, P = .50) and less than 12 hours (RR 0.98, 95% CI 0.71-1.35, P = .90). Misoprostol was not associated with an increased risk of tachysystole, hypertonus, or hyperstimulation syndrome when compared with oxytocin and had similar risks for adverse neonatal and maternal outcomes. CONCLUSION: Misoprostol is an effective and safe agent for induction of labor in women with term premature rupture of membranes. When compared with oxytocin, the risk of contraction abnormalities and the rate of maternal and neonatal complications were similar among the 2 groups.

Subcutaneous tissue reapproximation, alone or in combination with drain, in obese women undergoing cesarean delivery.

OBJECTIVE: To compare the efficacy of subcutaneous suture reapproximation alone with suture plus subcutaneous drain for the prevention of wound complications in obese women undergoing cesarean delivery. METHODS: We conducted a multicenter randomized trial of women undergoing cesarean delivery. Consenting women with 4 cm or more of subcutaneous thickness were randomized to either subcutaneous suture closure alone (n = 149) or suture plus drain (n = 131). The drain was attached to bulb suction and removed at 72 hours or earlier if output was less than 30 mL/24 h. The primary study outcome was a composite wound morbidity rate (defined by any of the following: subcutaneous tissue dehiscence, seroma, hematoma, abscess, or fascial dehiscence). RESULTS: From April 2001 to July 2004, a total of 280 women were enrolled. Ninety-five percent of women (268/280) had a follow-up wound assessment. Both groups were similar with respect to age, race, parity, weight, cesarean indication, diabetes, steroid/antibiotic use, chorioamnionitis, and subcutaneous thickness. The composite wound morbidity rate was 17.4% (25/144) in the suture group and 22.7% (28/124) in the suture plus drain group (relative risk 1.3, 95% confidence interval 0.8-2.1). Individual wound complication rates, including subcutaneous dehiscence (15.3% versus 21.8%), seroma (9.0% versus 10.6%), hematoma (2.2% versus 2.4%), abscess (0.7% versus 3.3%), fascial dehiscence (1.4% versus 1.7%), and hospital readmission for wound complications (3.5% versus 6.6%), were similar (P > .05) between women treated with suture alone and those treated with suture plus drain, respectively. CONCLUSION: The additional use of a subcutaneous drain along with a standard subcutaneous suture reapproximation technique is not effective for the prevention of wound complications in obese women undergoing cesarean delivery.

A cost-effectiveness analysis of chemotherapy for patients with recurrent platinum-sensitive epithelial ovarian cancer.

OBJECTIVE: The majority of patients with advanced epithelial ovarian cancer (EOC) will experience a recurrence after primary chemotherapy and receive second-line chemotherapy. Patients who have a disease-free interval >6 months (platinum-sensitive) will often receive multiple chemotherapy regimens. Therefore, our goal was to assess the effectiveness and medical costs of chemotherapy for platinum-sensitive patients with advanced EOC. METHODS: A decision analysis model compared several chemotherapeutic strategies in a hypothetical cohort of 10,000 platinum-sensitive EOC patients with recurrent disease: (a) best supportive care (BSC); (b) second-line monotherapy; (c) second-line combination therapy; (d) third-line chemotherapy after disease progression on second-line monotherapy or combination therapy; (e) fourth-line chemotherapy after disease progression on second- and third-line chemotherapy. RESULTS: BSC and second-line therapies were cost-effective strategies. The cost-effectiveness ratios ranged from $2896 for second-line monotherapy to $4914 for fourth-line previous monotherapy. Compared to BSC, second-line monotherapy gained an additional 8 months of overall survival (OS) with a favorable incremental cost-effectiveness ratio (ICER) of $24,228 per life year saved (LYS). The ICER for second-line combination therapy compared to second-line monotherapy was also favorable ($46,068 per LYS). Although third- and fourth-line chemotherapy provided small improvements in OS, they were dominated by other strategies or had an unfavorable ICER (>$50,000 per LYS). CONCLUSIONS: Second-line chemotherapy is cost-effective for patients with platinum-sensitive recurrent EOC. Due to minimal improvements in overall survival, third- and fourth-line chemotherapy are not cost-effective strategies.

Diagnostic loop electrosurgical excisional procedure for discrepancy: do preoperative factors predict presence of significant cervical intraepithelial neoplasia?

OBJECTIVE: Although pathological discrepancy between Pap smear and biopsy is an accepted indication to perform a diagnostic loop electrosurgical excision procedure (LEEP), this procedure is not without complications. Our objective was to determine the incidence of cervical intraepithelial neoplasia (CIN) 2,3 and patient factors that increase the likelihood of detecting CIN 2,3. MATERIALS AND METHODS: We performed a retrospective chart review of patients who underwent a diagnostic LEEP for pathological discrepancy at a university-based colposcopy clinic. Pathological discrepancy is defined as a high-grade Pap smear with a colposcopically directed biopsy of CIN 1 or less. Demographic, cytological, and histological information were collected using a computerized database. The patients were divided into 2 groups (CIN 2,3 and CIN 1 or less) based on the pathology from the LEEP specimen. Patient factors were compared with final pathological results using chi(2) test, Student t test, Wilcoxon rank sum test, and multivariate analysis as indicated. RESULTS: A total of 102 patients were identified. Seven patients had normal specimens, 3 had HPV changes, 25 had CIN 1, 29 had CIN 2, and 38 had CIN 3. Thirty-five patients (34%) had CIN 1 or less, whereas 67 patients (66%) had CIN 2,3. The 2 groups were comparable in terms of age (30.4 vs 28.1 years), parity (2.2 vs 1.9), and age of coitarche (16.3 vs 16.4 years). No statistical difference existed between the groups regarding race, smoking status, Pap smear, history of previous cytological abnormality, contraception method, number of previous sexual partners, and HIV status. The majority of patients (75%) had not undergone previous treatment of CIN. The CIN 2,3 group were more likely than the CIN 1 or less group to have had previous treatment or biopsy for CIN (66% vs 34%; p = .004). Univariate (p = .004) and multivariate (p < .001) analysis demonstrated previous treatment of CIN as the only significant factor predicting CIN 2,3. CONCLUSION: Two thirds of women undergoing a LEEP for pathological discrepancy between Pap smear and cervical biopsy will have CIN 2,3. Women that have had previous treatment of CIN are more likely to have CIN 2,3 detected on their LEEP specimen.

Role of chemotherapy for patients with recurrent platinum-resistant advanced epithelial ovarian cancer: A cost-effectiveness analysis.

BACKGROUND: Current chemotherapy in platinum-resistant ovarian cancer patients has demonstrated minimal to no improvements in survival. Despite the lack of benefit, significant resources are utilized with such therapies. Therefore, the objective in the current study was to assess the cost-effectiveness of salvage chemotherapy for patients with platinum-resistant epithelial ovarian cancer (EOC). METHODS: A decision analysis model evaluated a hypothetical cohort of 4000 platinum-resistant patients with recurrent EOC. Several chemotherapy strategies were analyzed: 1) best supportive care (BSC); 2) second-line chemotherapy-monotherapy; 3) second-line chemotherapy-combination therapy; 4) third-line chemotherapy after disease progression on second-line monotherapy; and 5) third-line chemotherapy after disease progression on second-line combination therapy. Sensitivity analyses were performed on all pertinent uncertainties. RESULTS: Using costs alone, BSC was the only definitive cost-effective treatment for platinum-resistant recurrent ovarian cancer patients, and second-line monotherapy was a reasonable cost-effective strategy with an incremental cost-effectiveness ratio (ICER) of 64,104 dollars. The cost-effectiveness ranged from 4,065 dollars per month of overall survival (OS) for BSC to 12,927 dollars for third-line previous combination therapy. Compared with BSC, second-line monotherapy gained an additional 3 months of OS, with a cost-effectiveness of 4,703 dollars per month of OS. Second-line combination therapy and third-line therapies exhibited unfavorable ICER. CONCLUSIONS: The current decision analysis was intended to be thought-provoking and bring awareness to the high costs of subsequent chemotherapy with limited effectiveness in patients with recurrent platinum-resistant EOC. Although actual patients may receive multiple lines of chemotherapy, from the perspective of costs alone this model using a hypothetical cohort demonstrated that best supportive care was the only cost-effective strategy, with second-line monotherapy appearing to be a reasonable cost-effective strategy given current chemotherapeutic options.

Effectiveness of darbepoetin alfa versus epoetin alfa for the treatment of chemotherapy induced anemia in patients with gynecologic malignancies.

OBJECTIVE: Chemotherapy induced anemia (CIA) commonly occurs in gynecologic oncology patients. This often leads to treatment with erythropoietic stimulating agents in order to prevent chemotherapy delays, dose modifications and transfusion of red blood cells. Our objective was to determine the subsequent transfusion rates following administration of either darbepoetin alfa or epoetin alfa. METHODS: A single institution retrospective chart review was performed utilizing patients from January 2003 to September 2004 who received either darbepoetin alfa or epoetin alfa for CIA (Hgb < or = 10.0). Data collection variables included patient demographics, cancer diagnosis, chemotherapy treatment(s), laboratory data, erythropoeisis stimulation data, and transfusions. Sample size calculations were set to detect a 20% transfusion rate difference between the two groups. Chi-square, Fisher exact test and student t tests were used for statistical analysis. RESULTS: 123 patients were eligible for analysis (60 darbepoetin alfa; 62 epoetin alfa). 93% of darbepoetin alfa patients received 200 mg every other week, while 86% of epoetin alfa patients received 40,000 U weekly. The darbepoetin alfa and epoetin alfa groups were similar in respect to age, race, tumor type, histology, previous chemotherapy, number of chemotherapy agents, weeks of erythropoietic stimulation, and baseline serum levels of creatinine and hemoglobin. The mean baseline Hgb and change in Hgb was similar for each group (darbepoetin alfa = 11.2, 2.5 and epoetin alfa = 11.3, 2.3). Twenty one (35%) of the darbepoetin alfa patients received a transfusion of packed red blood cells compared to 12 (19%) of epoetin alfa patients (p = 0.05). CONCLUSIONS: This retrospective analysis powered to detect differences in transfusion rates revealed a statistically significant difference in transfusion rates between darbepoetin alfa and epoetin alfa for the treatment of CIA. These data warrant a randomized prospective trial in gynecologic oncology patients with careful attention to the timing of initiation of treatment, dosing regimens, and titration of growth factor.

Spontaneous epidural hematoma of the spine in pregnancy.

Spontaneous spinal epidural hematomas are uncommon. Progressive neurologic deficits that are associated with epidural hematomas can develop rapidly and require prompt treatment. We present a case of spontaneous epidural hematoma of the thoracic spine that complicated a term pregnancy.

A case report of rhabdomyosarcoma of the uterus associated with uterine inversion.

BACKGROUND: Alveolar rhabdomyosarcoma is an uncommon malignant soft tissue tumor rarely found in the genital tract. This tumor is associated with a poor prognosis, especially in the adult population. Equally as rare are non-puerperal uterine inversions secondary to sarcomas. CASE: A 21-year-old obese woman was initially evaluated with excessive vaginal bleeding. On exam, a large pedunculated mass protruding from the cervix was seen and biopsy of this mass revealed an alveolar rhabdomyosarcoma. The patient was treated with adjuvant chemotherapy consisting of VAC (Vincristine, Actinomycin, and Cyclophosphamide) for a presumed cervical rhabdomyosarcoma. After five cycles of chemotherapy the patient underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy, at which time a complete uterine inversion was noted with the tumor located at the fundus of the uterus. Final pathology showed alveolar rhabdomyosarcoma of the uterus. The patient then received additional postoperative VAC regimen for a total of 10 treatments and remains in good health with no evidence of disease 20 months from diagnosis. CONCLUSION: This case report describes the only reported case of uterine inversion secondary to alveolar rhabdomyosarcoma of the uterus and discusses current therapeutic options for adults.
