Racial Disparities in Endometrial Cancer Clinical Trial Representation: Exploring the Role of Eligibility Criteria.

BACKGROUND: This study aimed to determine whether Black patients with recurrent endometrial cancer were more likely than White patients to be ineligible for a recently published clinical trial due to specific eligibility criteria. METHODS: Patients with recurrent or progressive endometrial cancer diagnosed from January 2010 to December 2021 who received care at a single institution were identified. Demographic and clinicopathologic information was abstracted and determination of clinical trial eligibility was made based on 14 criteria from the KEYNOTE-775 trial. Characteristics of the eligible and ineligible cohorts were compared, and each ineligibility criterion was evaluated by race. RESULTS: One hundred seventy-five patients were identified, 89 who would have met all inclusion and no exclusion criteria for KEYNOTE-775, and 86 who would have been ineligible by one or more exclusion criteria. Patients in the ineligible cohort were more likely to have lower BMI (median 26.5 vs. 29.2, P <0.001), but were otherwise similar with regard to insurance status, histology, and stage at diagnosis. Black patients had 33% lower odds of being eligible (95% CI: 0.33-1.34) and were more likely to meet the exclusion criterion of having a previous intestinal anastomosis, but the result was not statistically significant. If this criterion were removed, the racial distribution of those ineligible for the trial would be more similar (46.4% Black vs. 42.2% White). CONCLUSIONS: Clinical trial eligibility criteria may contribute to the underrepresentation of racial groups in clinical trials, but other factors should be explored. Studies to quantify and lessen the impact of implicit bias are also needed.

No Racial Disparities Observed Using Point-of-Care Genetic Counseling and Testing for Endometrial and Ovarian Cancer in a Diverse Patient Population: A Retrospective Cohort Study.

We investigated genetic counseling and testing rates for patients with gynecologic malignancy at a tertiary care center with a large minority population. Our retrospective cohort included newly diagnosed epithelial ovarian, fallopian tube, peritoneal, or endometrial cancer patients between January 2014 and June 2022. For endometrial cancer, 373 patients were identified. A total of 207 (55%) patients were screened using mismatch repair immunohistochemistry (MMR IHC). A total of 82 (40%) had MMR deficiencies on IHC. Of these, 63 (77%) received genetic counseling. A total of 62 (98%) underwent genetic testing, and ultimately, 7 (11%) were diagnosed with Lynch syndrome (LS). The overall rate of LS was 1.9%. MMR IHC testing increased steadily, reaching 100% in 2022. For ovarian cancer, 144 patients were identified. A total of 104 (72%) patients received genetic counseling, and 99 (95%) underwent genetic testing. Rates were not influenced by race, ethnicity, insurance type, or family history of cancer. They were significantly different by cancer stage (p < 0.01). The proportion of patients who received genetic counseling increased from 47% in 2015 to 100% in 2022 (p < 0.01). Most counseling was performed by a gynecologic oncologist (93%) as opposed to a genetic counselor (6.7%). Overall, 12 (8.3%) patients were BRCA+. High rates of counseling and testing were observed with few disparities.

Recurrent herpes simplex virus mimicking vulvar carcinoma in patient with Human Immunodeficiency Virus: A case report.

Patients with human immunodeficiency virus (HIV) are at increased risk for developing other gynecologic conditions, including herpes simplex virus (HSV) and vulvar intraepithelial neoplasia (VIN)/carcinoma. We describe the case of a woman with a history of microinvasive vulvar squamous cell carcinoma who presented with hypertrophic ulcerated vulvar and peri-anal masses concerning for malignancy. This case highlights the need to maintain a high index of suspicion for malignancy and herpes simplex virus, even with negative polymerase chain reaction (PCR) test, as well as the difficulty of treating this often-resistant lesion.

Optimal cytoreduction followed by chemoradiation in stage IVB uterine serous carcinoma.

OBJECTIVES: The prognosis of patients presenting with stage IVB uterine serous carcinoma (USC) remains extremely poor, with a reported 5-year survival of <20%. Here were evaluate the survival impact of cytoreductive surgery and identify other prognostic factors in stage IVB USC. METHODS: A multicenter retrospective analysis of patients with stage IVB USC was conducted from 2000 to 2018. Inclusion criteria were patients who had undergone comprehensive surgical staging/tumor debulking; followed by adjuvant chemotherapy+/-external beam radiation therapy (EBRT). Optimal cytoreduction (R1) was defined as residual disease ≤1 cm at completion of surgery, and suboptimal cytoreduction (R2) was defined as >1 cm. Progression free survival (PFS) and overall survival (OS) analysis was performed using Kaplan-Meier estimates. Multivariate analysis (MVA) was performed using Cox proportional hazards model. RESULTS: Final analysis included 68 patients. There was no difference in the frequency of treatment delays between regimens (p = 0.832). 96% of patients received platinum-based chemotherapy. There was no difference in the age (p = 0.227), race (p = 0.936), type of radiotherapy (p = 0.852) or chemotherapy regimen received (p = 0.996) between R1 and R2 cohorts. The median PFS for all patients was 8 months and the median OS was 13 months. Cytoreduction to R1 was associated with a median PFS of 9 months, compared to R2 with a median PFS of 4 months (p < 0.001, HR 0.32, 95% CI 7.4-14.1). Median OS was also improved with R1 vs. R2 cytoreduction (17 months vs. 7 months, respectively) (p < 0.001, HR 0.21, 95% CI 13.7-26.4). Compared to R1, cytoreduction to R0 was not associated with a survival benefit. The R0 median OS was 17 months versus 18 months in R1 (p = 0.67). The combination of adjuvant chemoradiation was associated with improved PFS (11 months vs. 7 months) (p = 0.024, HR 0.41, 95% CI 6.5-9.4) and OS (22 months vs 13 months) (p = 0.65, HR 0.25, 95% CI 10.5-15.4) compared to chemotherapy-alone, respectively. On MVA, only the amount of residual disease (p = 0.003, HR 0.39, 95% CI 0.2-0.7) and receipt of adjuvant chemoradiation (p = 0.010, HR 0.09, 95% CI 0.01-0.58) were independent predictors of survival. CONCLUSIONS: In stage IVB USC, optimal cytoreduction should be the goal at the time of primary surgery. The combination of chemoradiation was associated with superior survival compared to chemotherapy alone and should be further investigated in this patient population.

Fatalistic cancer beliefs and self-reported cancer screening behaviors among diverse urban residents.

Cancer fatalism-the belief that death is inevitable when cancer is present-has been identified as a barrier to cancer screening, detection, and treatment. Our study examined the relationship between self-reported cancer fatalism and adherence to cancer screening guidelines of the breasts, cervix, colon, and prostate among a diverse sample of urban-dwelling adults in Brooklyn, New York. Between May 2019 and August 2020, we conducted a cross-sectional survey of adults 40 + years of age (n = 2,341) residing in Brooklyn neighborhoods with high cancer mortality. Multivariable logistic regression models were used to assess the odds of reporting cancer screening completion across three fatalistic cancer belief categories (low, med, high). Participants' median age was 61 (IQR 51, 71) years, 61% were women, 49% self-identified as non-Hispanic black, 11% Hispanic, 4% Asian, and 6% more than one race. There were no statistically significant differences in the proportion of low, some, or high fatalistic beliefs identified among male respondents compared to women. Among women, we observed that high fatalistic cancer beliefs were associated with higher odds (OR 2.01; 95% CI 1.10-3.65) of completing breast but not cervical (1.04; CI 0.55-1.99) or colon (1.54; CI 0.88-2.69) cancer screening. Men with high fatalistic cancer beliefs had a trend towards lower odds of prostate screening (OR 0.53: 95% CI 0.18-1.57) compared to men with low fatalistic beliefs, but neither was statistically significant. Findings suggest that high fatalistic cancer beliefs may be an important factor in cancer screening utilization among women. Further examination in longitudinal cohorts with a larger sample of men may be needed in order to identify any significant effect.

Evaluation of Survival, Recurrence Patterns and Adjuvant Therapy in Surgically Staged High-Grade Endometrial Cancer with Retroperitoneal Metastases.

BACKGROUND: We seek to evaluate the difference in recurrence patterns and survival among stage IIIC high-grade endometrial cancer treated with surgery followed by adjuvant chemotherapy alone, radiation therapy alone, or both (chemoradiation). METHODS: A multicenter retrospective analysis of surgically staged IIIC HGEC receiving adjuvant therapy was conducted. HGEC was defined as grade 3 endometrioid adenocarcinoma, serous, clear cell and carcinosarcoma. Differences in the frequency of recurrence sites and treatment delays were identified using Pearson's χ2 test. Progression-free survival (PFS) and overall survival (OS) were calculated using Kaplan-Meier estimates. RESULTS: A total of 155 patients were evaluable: 41.9% carcinosarcoma, 36.8% serous, 17.4% grade 3 and 3.9% clear cell. Of these, 67.1% received chemoradiation, 25.8% received chemotherapy and 7.1% received radiation therapy. There was no difference in the frequency of treatment delays between regimens (p = 0.571). There was a trend towards greater retroperitoneal recurrence with chemotherapy (25.9%) versus chemoradiation (8.4%) and radiation therapy (7.7%) (p = 0.252). Grade 3 tumors had improved progression-free and overall survival (26 and 42 months, respectively) versus serous (17 and 30 months, respectively), carcinosarcoma (14 and 24 months, respectively) and clear cell (24 and 30 months respectively) (p = 0.002, p < 0.001). Overall, chemoradiation was superior to chemotherapy and radiation therapy in PFS (p < 0.001) and OS (p < 0.001). Upon multivariate analysis, only histology and receipt of chemoradiation were independent predictors of survival. CONCLUSION: The majority of stage IIIC high-grade endometrial carcinomas recurred. Chemoradiation was associated with improved survival and less retroperitoneal recurrence. Grade 3 tumors demonstrated improved survival versus other histologies regardless of adjuvant treatment modality.

Breast metastases: A rare manifestation of advanced uterine serous carcinoma.

Metastasis of non-mammary tumors to the breast are uncommon, representing <1% of all breast tumors. Breast metastasis are associated with advanced disease and poor prognosis regardless of the origin of the primary tumor. Uterine cancer metastasis to the breast is an extremely rare finding and has not been reported in the case of serous histology. Here, we review two cases of uterine serous carcinoma metastatic to the breast. Both patients presented with breast-specific complaints including pain and palpable mass and were found to have widely metastatic disease. Tissue biopsy and immunohistochemistry consistent with primary uterine serous carcinoma confirmed the diagnosis of metastasis in both cases. Our findings suggest hematogenous metastasis to the breast is a late phenomenon in the course of endometrial carcinoma and associated with the development of disease at multiple sites. This emphasizes the importance of complete evaluation in patients presenting with breast complaints and known history of malignancy, as this may be the only presenting symptoms in patients with widely metastatic disease.

Clinical comparison between neuroendocrine and endometrioid type carcinoma of the uterine corpus.

OBJECTIVE: To compare the clinicopathologic features and survival outcomes of neuroendocrine tumor of the uterine corpus (NET-U) to endometrioid type endometrial carcinoma (EC). METHODS: From 1993 to 2012, the Surveillance, Epidemiology and End Results cancer registry was queried for women diagnosed with EC or NET-U. Data regarding stage, grade, presence of extra-uterine disease, lymph node metastasis, receipt of adjuvant radiation, surgical intervention and overall survival (OS) was extracted. Chi-square tests, t-tests and Kaplan Meir curves were used for statistical analysis. RESULTS: A total of 98,363 patients were identified: 98,245 with EC and 118 with NET-U. The mean age at diagnosis for EC was 61.7 years and 64.8 years for NET-U (p=0.01). NET-U cases were more likely to be poorly differentiated (97.0% vs. 15.6%; p≤0.01) and have nodal metastasis (56.4% vs. 11.1%; p≤0.01) when compared to EC. Presence of extrapelvic disease at the time of diagnosis was observed more frequently in NET-U compared to EC, 49.1% vs. 4.8%, respectively (odds ratio=18; 95% confidence interval=13.1-27.2; p≤0.01). Significant improvement in OS was observed in NET-U patient who received radiation (OS: 7.7 vs. 3.3 years; p≤0.01) or underwent surgical management (5.6 vs. 0.9 years; p≤0.01). The OS for EC was 14.4 vs. 4.6 years for NET-U (p≤0.01). CONCLUSION: NET-U represents an aggressive form of uterine malignancy. When compared to EC, patients with NET-U present at more advanced stage, have more frequent extra-uterine disease and lower OS.

Clinicopathologic features, incidence, and survival trends of gynecologic neuroendocrine tumors: a SEER database analysis.

BACKGROUND: Primary gynecologic neuroendocrine tumors are uncommon malignant neoplasms associated with poor prognosis. Clinically, these tumors present a significant challenge because of the lack of standardized management guidelines. OBJECTIVE: The objective of this study is to evaluate the clinicopathologic features, incidence, and survival trends in gynecologic neuroendocrine tumors. MATERIALS AND METHODS: The Surveillance, Epidemiology and End Results (SEER) cancer registry was queried for women diagnosed with primary gynecologic neuroendocrine tumors from 1987 to 2012. Data regarding stage, grade, presence of extrauterine disease, receipt of adjuvant radiation, surgical intervention, incidence, and overall survival were extracted. Patients were classified as having early-stage disease (International Federation of Gynecology and Obstetrics Stage I/II) or advanced-stage disease (Stage III/IV). Extrauterine disease was defined as either regional or distant metastasis. χ2 Tests, Pearson correlation, and Kaplan-Meier curves were used for statistical analysis. RESULTS: In all, 559 cases of gynecologic neuroendocrine tumors were identified during the study period: 242 cervical, 160 ovarian, 118 uterine, and 39 vulvar/vaginal. The majority of patients in all subsets of gynecologic neuroendocrine tumors presented with poorly differentiated tumors, extrauterine disease spread, and advanced-stage disease. Poorly differentiated tumors represented 65.0% of cervical tumors, 45.3% of ovarian tumors, and 57.4% of uterine tumors. Extrauterine disease at the time of diagnosis was present in the case of 66.9% of cervical tumors, 83.5% of ovarian tumors, and 83.6% of uterine tumors. The overall incidence of gynecologic neuroendocrine tumors increased 4-fold during the study period, from 0.3 in 1987 to 1.30 per million in 2012. The study period was divided into two 13-year periods (1987-1999 and 2000-2012) for time trend mean survival analysis. We observed no significant change in overall survival across all gynecologic neuroendocrine tumor subtypes. The mean survival time of cervical neuroendocrine tumors was 74.3 vs 45.4 months (P = .31), ovarian neuroendocrine tumors 47.8 vs 41.2 months (P = .56), and uterine neuroendocrine tumors 42.9 vs 47.7 months (P = .44) for each time period, respectively. CONCLUSION: Neuroendocrine tumors of the gynecologic tract are uncommon aggressive malignancies. These poorly differentiated tumors present at advanced stage, with a high incidence of extrauterine disease. Despite 25 years of advances in cancer therapy, we observed no improvement in overall survival.

Hospice utilization in advanced cervical malignancies: An analysis of the National Inpatient Sample.

OBJECTIVE: Hospice services improve quality of life and outcomes for patients and caretakers, compared to inpatient mortality. This study identifies factors that exert the strongest influence on end-of-life care modalities in patients with cervical cancer. METHODS: Admissions with a diagnosis of cervical cancer that were discharged to hospice or died in-hospital were identified in the National Inpatient Sample years 2007-2011, excluding admissions coded for hysterectomy. Logistic regression models were used to examine differences in age, race, length of stay, primary payer, hospital region, admission type, hospital bedsize, hospital teaching status, income quartile, and Elixhauser comorbidity index score between the groups. RESULTS: 2073 admissions with a diagnosis of cervical cancer resulting in hospice discharge (n = 1290) or inpatient death (n = 783) were identified. Age (P = 0.01), hospital region (P = 0.01), length of hospitalization (P < 0.01), Elixhauser comorbidity index score (P = 0.03), and urban vs. rural location (P = 0.01) had a significant impact on disposition in univariate analysis. Admissions of patients categorized as Asian/Pacific Islander (OR = 2.24, 95% CI 1.11-4.49), hospitalizations lasting 0-3 days (OR = 1.57, 95% CI 1.21-2.03), and admissions in rural areas (OR = 1.62, 95% CI 1.12-2.36) had higher rates of in-hospital death compared to the reference groups. Patients aged 18-45 years (OR = 0.69, 95% CI 0.52-0.90) and those treated in the South (OR 0.59, 95% CI 0.45-0.77) and West (OR = 0.50, 95% CI 0.30-0.81) had lower odds ratios of inpatient mortality. CONCLUSION: Modalities of care in terminal cervical cancer vary among sociodemographic and clinical factors. This data underscores the continued push for improved end-of-life care among cervical cancer patients and can guide clinicians in appropriate targeted counseling to increase utilization of hospice resources.

A small molecule inhibitor of the perinucleolar compartment, ML246, attenuates growth and spread of ovarian cancer.

BACKGROUND: Ovarian cancer remains a major health problem for women as it is often diagnosed at a late stage with metastatic disease. There are limited therapeutic agents and survival rates remain poor. The perinucleolar compartment (PNC) has been shown to be associated with malignancy and is considered a surrogate phenotypic marker for metastatic cancer cells. A small molecule, ML246, was derived from a screen against PNCs. In this study, the effect of ML246 on ovarian cancer growth and spread was investigated. METHODS: SKOV3 or OVCAR3 cells were treated with ML246 in vitro and PNC was visualized with immunofluorescent staining. Cell invasion was assessed using Matrigel-coated transwell systems. SKOV3 cells were xenografted orthotopically under the ovarian bursa of immunocompromised mice. Additionally, a patient derived ovarian cancer cell line was grafted subcutaneously. Mice were treated with ML246 and tumor growth and spread was assessed. RESULTS: PNCs were prevalent in the ovarian cancer cell lines OVCAR3 and SKOV3 with higher prevalence in OVCAR3 cells. Treatment with ML246 significantly reduced PNC prevalence in OVCAR3 and SKOV3 cells. Moreover, the invasive activity of both cell lines was significantly inhibited in vitro. Orthotopic implantation of SKOV3 cells resulted in growth of the tumor on the ovary as well as spread of tumor tissues outside of the primary site on organs into the abdominal cavity. Treatment with ML246 decreased the incidence of tumors outside of the ovary. In addition, a patient-derived xenograft (PDX) line was grafted subcutaneously to monitor tumor growth. ML246 significantly attenuated growth of tumors over a 5-week treatment period. CONCLUSIONS: PNC's are present in ovarian cancer cells and treatment with ML246 decreases invasion in vitro and tumor growth and spread in vivo. Additional studies are warranted to determine the efficacy of ML246 as an inhibitor of metastatic disease in ovarian cancer and to determine its precise mechanism of action.

Role of adjuvant external beam radiotherapy and chemotherapy in one versus two or more node-positive vulvar cancer: A National Cancer Database study.

BACKGROUND AND PURPOSE: Inguinal lymph node involvement is considered the most important prognostic risk factor for survival in vulvar cancer. However, controversy exists concerning the optimal adjuvant therapy for node-positive disease. This study sought to identify the optimal adjuvant therapy for each subset of women with node-positive disease. MATERIAL AND METHODS: The National Cancer Database (NCDB) was queried to identify women with inguinal node positive vulvar cancer. Survival analysis was performed using log-rank test, the Kaplan-Meier estimates, and Cox proportional hazards to both clarify prognosis and identify the benefit of each treatment modality in individual subsets of women. RESULTS: A total of 2779 women with inguinal node positive vulvar cancer were identified. On multivariate Cox model hazard ratio, radiotherapy yielded a survival advantage for women with one positive node (HR 0.81, p = 0.027) and two or more positive nodes (HR = 0.59, p < 0.001). The addition of chemotherapy to radiotherapy yielded an incremental improvement in survival for women with 2 or more positive nodes (HR = 0.79, p = 0.022) but not women with 1 positive node (HR = 0.93, p = 0.605). CONCLUSIONS: All patients with node positive disease benefited from radiotherapy. By contrast, only those with 2 or more positive nodes benefited from the addition of chemotherapy to radiotherapy.

Comparison among fertility-sparing therapies for well differentiated early-stage endometrial carcinoma and complex atypical hyperplasia.

OBJECTIVE: To compare fertility-sparing therapies including oral progestogens, hysteroscopic resection (HR), and the levonorgestrel- releasing intrauterine system (LNG-IUS) in achieving disease regression, recurrence and live birth rate in well differentiate early-stage endometrial carcinoma (eEC) and complex atypical hyperplasia(CAH). STUDY DESIGN: This was a meta-analysis of previous studies focus on the fertility-sparing therapy for well differentiate early-stage endometrial carcinoma (eEC) and complex atypical hyperplasia (CAH). DATE SOURCES: Medline, the Cochrane Library and Embase was searched with the terms and Synonyms: words similar to eEC and CAH with therapies associated with fertility-sparing. MAIN OUTCOME MEASURES: The number of all patients accepted fertility sparing therapies, patients got regressed, relapsed and delivered were extracted from each study, and the regression, recurrence, and live birth rate of each study were calculated. The regression, recurrence and live birth rates between each two interventions were compared with the aid of meta-regression in packages of "meta" and "meta for" written in R. RESULTS: Fifty-four studies reported fertility sparing therapies in young women with eEC and CAH were included. Meta-analysis showed that HR followed by progestogens achieved a higher pooled regression (98.06% vs 77.20% P < 0.0001) and live birth rate (52.57% vs 33.38%, P = 0.0944) and a lower recurrence rate compared with oral progestogens alone (4.79% vs 32.17% P = 0.0004). At the same time, the pooled live birth rate (52.57% vs 18.09% P =0.0399) of HR followed by progestogens are significantly higher than the LNG-IUS alone. Which no statistical difference in regression (98.06% vs 94.24%; P = 0.4098) and recurrence rates (4.79% vs 3.90% P = 0.8561) was seen. CONCLUSIONS: Of the available fertility-sparing therapeutic options, HR followed by progestogens may be a more effective one.

Oncologic and obstetrical outcomes with fertility-sparing treatment of cervical cancer: a systematic review and meta-analysis.

OBJECTIVE: The objectives of this study were to evaluate the rates of recurrence, survival and pregnancy, and characterize pregnancy outcomes of early-stage cervical cancer(eCC) treated with fertility-sparing methods such as cervical conization (CON) and radical trachelectomy(RT) with or without pelvic lymphadenectomy. STUDY DESIGN: This was a meta-analysis of observational studies analyzed by a random-effects model and a meta-regression to assess heterogeneity. RESULTS: Sixty observational studies encompassing 2,854 patients were included; 17 of which evaluated CON and 43 RT. Three hundred and seventy-five patients were included in the CON group: 176(46.9%) stage IA1 and 167(44.5%) stage IB1. In the RT group, 2479 cases were included: 143(6.0%) stage IA1, 299(12.1%) stage IA2, 1987(79.9%) stage IB1. CON was performed in 347(92.5%) cases, resulting in a recurrence rate of 0.4%(95%CI: 0.0%-1.4%), a death rate of 0%(0%-0%), a pregnancy rate of 36.1%(26.4%-46.2%), a spontaneous abortion rate of 14.8%(9.3%-21.2%) and a preterm delivery rate of 6.8%(1.5%-15.5%). For the RT group, 2273(91.7%) underwent successful surgeries with a recurrence rate of 2.3%(1.3%-3.4%),a death rate of 0.7%(0.3%-1.1%), a pregnancy rate of 20.5%(16.8%-24.5%), a spontaneous abortion rate of 24.0%(18.8%-29.6%) and a preterm delivery rate of 26.6%(19.6%-34.2%). From a subgroup analysis, the recurrence rates for stage IA tumors treated with CON and RT were 0.4%(0.0%-1.9%) and 0.7%(0.0%-2.3%), respectively; and for stage IB were 0.6%(0.0%-2.7%) and 2.3%(0.9%-4.1%). CONCLUSION: Fertility-sparing treatment including CON or RT for eCC is feasible and carefully selected women can preserve fertility and achieve pregnancy resulting in live births. CON seems to result in better pregnancy outcomes than RT with similar rates of recurrence and mortality.

Is it necessary to perform routine appendectomy for mucinous ovarian neoplasms? A retrospective study and meta-analysis.

OBJECTIVES: To evaluate whether routine appendectomy is necessary in all patients with mucinous borderline ovarian tumor (mBOT) or mucinous ovarian cancer (MOC) who undergo gynecologic surgery. METHODS: The database of Qilu Hospital was searched for women who underwent appendectomy in a primary surgery for an ovarian tumor between June 2005 and June 2015 and whose final diagnosis was mBOT, MOC or primary appendiceal tumor. A retrospective review was performed, as well as a meta-analysis of the literature to further validate the findings. RESULTS: Seventy-one patients, 29 with mBOT and 42 with malignant mucinous tumors (including 40 with primary MOC and 2 with appendiceal mucinous adenocarcinoma), underwent appendectomy at the time of primary surgery. Among those with mBOT, two (6.9%) appendices were grossly abnormal and pathologically diagnosed with appendiceal implantation by mBOT. In the 42 patients with malignant disease, five (12%) appendices had a grossly abnormal appearance, one (2.4%) was diagnosed with an appendiceal metastasis from MOC and two (4.7%) were primary appendiceal adenocarcinoma. For grossly normal appendices, only one (2.4%) was confirmed to have microscopic metastasis from MOC. The meta-analysis included a total of 914 mBOT and MOC cases with appendectomies, including our current cases. The estimated rate of overall appendiceal pathology is 4.97%, and the pooled odds ratio (OR) showed statistical differences between MOC and mBOT (MOC vs. mBOT, OR=2.15, P<0.05). The estimated malignant pathology rate in macroscopically normal vs. abnormal appendices is 1.4% and 59%, respectively, with an estimated OR up to 97.5 (95% CI 28.1-338.5, P<0.05). CONCLUSION: There is not sufficient evidence to support a routine appendectomy for patients with a grossly normal appendix in mBOT and MOC. A careful intra-operative exploration of the appendix is crucial, but appendectomy is only warranted when the appendix is abnormal.

Receipt of vaginal brachytherapy is associated with improved survival in women with stage I endometrioid adenocarcinoma of the uterus: A National Cancer Data Base study.

BACKGROUND: Randomized controlled trials have consistently shown that the use of postoperative radiotherapy (RT) for stage I endometrial cancer leads to a reduction in the incidence of pelvic recurrences without a corresponding reduction in overall mortality. It was hypothesized that a reduction in mortality associated with the receipt of RT could be identified in a large data set with greater statistical power. METHODS: Women with surgically staged IA or IB endometrial adenocarcinoma who were treated with total hysterectomy between 2003 and 2011 were identified in the National Cancer Data Base. Chi-square tests and multivariate logistic regression were performed to analyze factors associated with the treatment type. A survival analysis was performed with log-rank testing, Cox proportional hazards regression, and Kaplan-Meier estimates. RESULTS: A total of 44,309 eligible women were identified (33,380 at stage IA and 10,929 at stage IB): 88.4% of the women with stage IA tumors and 51.6% of the women with stage IB tumors received no RT. Older age, comorbid disease, a higher histologic grade, and a larger tumor size were independently associated with an increase in mortality. The receipt of vaginal brachytherapy (VB) was independently associated with a reduction in mortality for both stage IA disease (hazard ratio [HR], 0.81; 95% confidence interval [CI], 0.67-0.97) and stage IB disease (HR, 0.62; 95% CI, 0.51-0.74). CONCLUSIONS: Analyses of this large database support the utility of postoperative VB for many women with stage I endometrial cancer. Unfortunately, RT appears to be underused in this population. Greater adherence to consensus guidelines may lead to improved outcomes. Cancer 2016;122:3724-31. © 2016 American Cancer Society.

Pulmonary Resection in the Management of High-Risk Gestational Trophoblastic Neoplasia.

OBJECTIVE: The aim of this study was to evaluate the role of pulmonary resection in the management of high-risk gestational trophoblastic neoplasia (GTN). METHODS: Patients who underwent pulmonary resection as part of their treatment for chemotherapy-resistant high-risk GTN from 1986 and 2014 were retrospectively analyzed. All patients had received 1 or more multiagent chemotherapy regimens preoperatively. Patient and disease characteristics were evaluated with respect to outcome. RESULTS: Fifteen (26%) of 58 patients treated for high-risk GTN underwent pulmonary resection with curative intent. Mean age of patients was 29 years (range, 19-37 years). International Federation of Gynecology and Obstetrics stage was III in 12 and IV in 3. International Federation of Gynecology and Obstetrics scores ranged from 5 to 20 (mean, 10). Antecedent pregnancy was nonmolar in 11 patients (73%). Adjuvant surgical procedures other than pulmonary resection were performed in 8 patients (53%). Preoperative chemotherapy regimens ranged from 1 to 10 (median, 4) and courses numbered from 2 to 32 (median, 14). Preoperative human chorionic gonadotropin (hCG) levels ranged from 2 to 2786 mIU/mL (median, 177 mIU/mL). Pulmonary wedge resections or lobectomies were performed via video-assisted thoracoscopic surgery (11) or thoracotomy (4). Two patients underwent pulmonary resections on 2 separate occasions. No patient had complications as a result of these procedures. Eleven patients (73%) were cured. In these 11 patients, hCG levels decreased to less than 2 mIU/mL within 6 to 52 days (mean, 22 days) postoperatively. CONCLUSIONS: Pulmonary resection of chemotherapy-resistant GTN was an important component of treatment in 26% of high-risk patients, 73% of whom were cured.

Treating Locally Advanced Cervical Cancer With Concurrent Chemoradiation Without Brachytherapy in Low-resource Countries.

OBJECTIVE: To summarize the literature on options of management of patients treated for locally advanced cervical cancers with a specific focus on resource-constrained settings where brachytherapy is not available. MATERIALS AND METHODS: A Medline search was performed to summarize studies about treatment approaches including neoadjuvant chemotherapy, primary surgery for bulky cervical cancer, and chemoradiation followed by surgery. Summaries are by treatment approaches that are relevant to resource-constrained settings. RESULTS: There are a lack of studies performed on neoadjuvant chemotherapy in low-resource settings. Primary surgery followed by chemoradiation therapy for selected patients with bulky cervical cancer is a feasible option. The disadvantage is the potential increase in treatment complications. Chemoradiation without brachytherapy followed by surgery has been found to have equivalent outcomes and is associated with acceptable morbidity. CONCLUSIONS: In resource-constrained settings where brachytherapy is not available, performing radical hysterectomy after chemoradiation therapy without brachytherapy has been shown to produce equivalent outcomes. It seems reasonable to adopt a modified therapeutic protocol of chemoradiation followed by extrafascial hysterectomy as an alternative treatment option in low-resource countries where brachytherapy is not readily available.
