OBJECTIVE:Gestational trophoblastic neoplasia are a group of diseases with few data given their rarity. The aim of this study was to determine the age and racial differences in the presentation and survival of patients with gestational trophoblastic neoplasia in the United States. METHODS:Data were collected from the National Cancer Database from January 2004 to December 2014. Chi-square tests, Cox regression, and Kaplan-Meier models were performed. Demographic characteristics included age at diagnosis, race, insurance status, facility location and type, community median income, high school dropout rate, education, income, and population density data. RESULTS:There were 1004 eligible patients including 64% white (n=645), 23% black (n=233), and 8.3% Asian patients (n=83). Median age was 30.8 (range 14-59) years. Stage I, II, III, IV, and unknown were diagnosed in 32%, 5.4%, 30%, 18%, and 15% of patients, respectively, with 5-year survival of 99%, 93%, 94%, 72%, and 95%, respectively (p<0.001). Compared with national birth rates, those with gestational trophoblastic neoplasia were overrepresented at younger (age 10-19 years: 8.2% vs 4.8%) and older ages (age 40-54 years: 17% vs 3.3%). The extremes of age at presentation were more pronounced in black patients with gestational trophoblastic neoplasia (age 10-19 years: 11% vs 6.9%, 40-54 years: 18% vs 3.2%), and black patients constituted 23% of patients compared with 15% of births nationwide. Some 59% of patients were treated at Academic/Research Programs. Only 6/448 (1.3%) facilities treated more than one patient per year, and only 9% (n=92) of patients were treated at one of these high-volume facilities. On multivariable analysis, older age, higher Charlson/Deyo co-morbidity score, and higher stage disease were independently associated with worse survival (all p<0.001). CONCLUSIONS:Gestational trophoblastic neoplasia was disproportionately higher in those at extremes of age and in black women as compared with United States national data. The lack of centralization of care justifies the need to develop regional centers of excellence for this rare malignancy.

INTRODUCTION:Fifteen per cent of women with cervical cancer are diagnosed with advanced disease and carry a 5 year survival rate of only 17%. Cervical cancer may lead to particularly severe symptoms that interfere with quality of life, yet few studies have examined the rate of palliative care referral in this population. This study aims to examine the impact of palliative care referral on women who have died from cervical cancer in two tertiary care centers. METHODS:We conducted a retrospective review of cervical cancer decedents at two tertiary institutions from January 2000 to February 2017. We examined how aggressive measures of care at the end of life, metrics defined by the National Quality Forum, interacted with clinical variables to understand if end-of-life care was affected. Univariate and multivariate parametric and non-parametric testing was used, and linear regression models were generated to determine unadjusted and adjusted associations between aggressive measures of care at the end of life with receipt of palliative care as the main exposure. RESULTS:Of 153 cervical cancer decedents, 73 (47%) received a palliative care referral and the majority (57%) of referrals occurred during an inpatient admission. The median time from palliative care consultation to death was 2.3 months and 34% were referred to palliative care in the last 30 days of life. Palliative care referral was associated with fewer emergency department visits (OR 0.18, 95% CI 0.05 to 0.56), inpatient stays (OR 0.21, 95% CI 0.07 to 0.61), and intensive care unit admissions (OR 0.24, 95% CI 0.06 to 0.93) in the last 30 days of life. Palliative care did not affect chemotherapy or radiation administration within 14 days of death (p=0.36). Women evaluated by palliative care providers were less likely to die in the acute care setting (OR 0.19, 95% CI 0.07 to 0.51). DISCUSSION:In two tertiary care centers, less than half of cervical cancer decedents received palliative care consultations, and those referred to palliative care were often evaluated late in their disease course. Palliative care utilization was also associated with a lower incidence of poor-quality end-of-life care.

OBJECTIVES:To determine the long-term potential benefit of adjuvant chemotherapy in subgroups of high-risk stage I mucinous ovarian cancer patients using a predictive scoring algorithm. METHODS:Data were collected from the National Cancer Database from 2004 to 2014. Based on demographic and surgical characteristics, a novel 10-year survival prognostic scoring system was developed using Cox regression. RESULTS:There were 2041 eligible patients with stage I mucinous ovarian cancer including 1362 (67%) with stage IA/IB disease, 598 (29%) with stage IC disease, and 81 (4%) with stage I disease not otherwise specified. Median age was 52 with a range of 13-90 years old. 737 (36%) patients were treated with adjuvant chemotherapy. Adjuvant chemotherapy was more common in patients with stage IC relative to stage IA/IB disease (69% vs. 21%, P < 0.001) or with poorly-differentiated relative to well-differentiated tumors (69% vs. 23%, P < 0.001). Unadjusted 10-year survival was 81% relative to 79% for patients treated with vs. without chemotherapy, respectively (P = 0.46). Patients were predicted to exhibit a low- or a high-risk of death using a multivariate Cox regression model with age, stage, grade, lymphovascular space invasion and ascites. Risk of death without vs. with adjuvant chemotherapy was similar in low-risk patients (88% vs. 84%; HR = 0.80, 95%CI = 0.56-1.15, P = 0.23) and worse in high-risk patients (51% vs. 74%; HR = 1.58, 95%CI: 1.05-2.38, P = 0.03) with stage I mucinous ovarian cancer. CONCLUSIONS:A predictive scoring algorithm may provide prognostic information on long-term survival and identify high-risk stage I mucinous ovarian cancer patients who might achieve a survival benefit from adjuvant chemotherapy.

OBJECTIVE:Vulvar cancers account for 5% of all gynecologic malignancies; only 1%-3% of those vulvar cancers are primary vulvar sarcomas. Given the rarity of vulvar sarcomas, outcome data specific to histopathologic subtypes are sparse. The aim of this study was to identify clinical and pathologic factors of primary vulvar sarcomas that are associated with survival and may inform treatment decisions. METHODS:and t-tests, Kaplan-Meier survival, and Cox regression analyses. RESULTS:The most common histopathologies of vulvar sarcomas were dermatofibrosarcomas (85/315, 27%) and leiomyosarcomas (72/315, 22.9%). Rhabdomyosarcomas (18/315, 5.7%), liposarcomas (16/315, 5.1%), and malignant fibrous histiocytomas (16/315, 5.1%) were less frequent. The majority of patients underwent surgery (292/315, 92.7%), which included lymph node dissections in 21.6% (63/292). Survival and lymph node involvement varied significantly with histologic subtype. The 5-year disease-specific survival for dermatofibrosarcomas, liposarcomas, and fibrosarcomas was 100% and only 60.3% and 62.5% for malignant fibrous histiocytomas and rhabdomyosarcomas, respectively. None of the patients with (dermato)fibrosarcomas, liposarcomas, or leiomyosarcomas had positive lymph nodes, in contrast to rhabdomyosarcomas and malignant fibrous histiocytomas with 77.8% and 40% positive lymph nodes, respectively. The 5-year disease-specific survival for women with positive lymph nodes was 0%. CONCLUSIONS:Vulvar sarcomas are heterogeneous with survival highly dependent on the histopathologic subtype. While surgical excision is the mainstay of treatment for all vulvar sarcomas, staging lymphadenectomy should be deferred for (dermato)fibrosarcomas, liposarcomas, and leiomyosarcomas as there were no cases of lymph nodes metastases.

OBJECTIVE:To investigate the utility of asymptomatic screening, including CA-125, imaging, and pelvic exam, in the diagnosis and management of recurrent ovarian cancer. METHODS:Women with ovarian cancer whose cancer recurred after remission were categorized by first method that their provider suspected disease recurrence: CA-125, imaging, symptoms, or physical exam. Differences in clinicopathologic, primary treatment characteristics, and outcomes data including secondary cytoreductive surgery (SCS) outcome and overall survival (OS) were collected. RESULTS:102 patients were identified at our institution from 2003 to 2015. 20 recurrences were detected by symptoms, while 62 recurrences were diagnosed first by asymptomatic rise in CA-125, 5 by pelvic exam, and 15 by imaging in the absence of known exam abnormality or rise in CA-125.Mean time to recurrence was 18.9 months, and median survival was 45.8 months. These did not vary by recurrence detection method (all p > 0.4). Patients whose disease was detected by CA-125 were less likely to undergo SCS than those detected by other means (21.7% vs. 35.0%, p = 0.007). In addition to the 5 patients whose recurrence was detected primarily by pelvic exam, an additional 10 (total n = 15) patients had an abnormal pelvic exam at time of diagnosis of recurrence. DISCUSSION/CONCLUSIONS:Recurrence detection method was not associated with differing rates of survival or optimal SCS, however those patients detected by CA-125 were less likely to undergo SCS. The pelvic exam was a useful tool for detecting a significant proportion of recurrences.

STUDY OBJECTIVE:To evaluate practice patterns among gynecologic oncologists with regard to sentinel lymph node injection and biopsy in endometrial cancer. DESIGN:An observational study with no control group. SETTING AND PATIENTS:Active members of the Society of Gynecologic Oncology. INTERVENTIONS:After institutional review board approval, we performed an online survey among active members of the Society of Gynecologic Oncology. Members were contacted via e-mail and their answers anonymously captured. Study data were collected using REDCap (REDCap developed by Vanderbilt University, Nashville TN). MEASUREMENTS AND MAIN RESULTS:Three hundred eighteen of 1216 listed members completed the online survey. The majority of respondents (82.7%) perform sentinel lymph node sampling for endometrial cancer staging. Most technical aspects of sentinel lymph node sampling were consistently applied by the vast majority of respondents, including the choice of indocyanine green as a lymphatic tracer (97.3%) and its injection into the cervix (100%). Other technical aspects of sentinel lymph node sampling, such as the depth of injection, varied among respondents. Although 50.9% of the respondents perform an intraoperative assessment of the uterus by frozen section, only 17.9% assess sentinel lymph nodes by frozen section and/or touch prep. Some of the respondents' approaches are based on limited data, including (1) the use of sentinel lymph node injection and biopsy for high-risk histologies (performed by 69%-75% of the respondents dependent on the histology), (2) omitting side-specific completion lymphadenectomy in the absence of sentinel node mapping (in up to 57.8%), or (3) when lymph node metastases are present (in 39.9%). CONCLUSION:In summary, despite the growing use of sentinel lymph node injection and biopsy in endometrial cancer, practice patterns vary considerably among providers sampled by this survey. Some of the decisions are based on limited evidence and, in some instances, deviate from current published guidelines.

OBJECTIVE:This study aims to understand the treatment patterns and clinical outcomes of older women with cervical cancer compared to younger women. METHODS:Women undergoing care for cervical cancer between 2000 and 2013 at two academic institutions were identified. The cohort of older patients was defined as >65 years old at diagnosis. Patient charts were retrospectively reviewed, and clinical variables were extracted. Fisher's exact tests, logistic regression, and Kaplan-Meier analyses were performed. RESULTS:From 2000 to 2013 1119 women with cervical cancer were identified. Of these, 191 (17.0%) were >65 years old at the time of diagnosis. Older women were more likely to present with higher stage disease (p < 0.001). Controlling for stage, older women were less likely to undergo surgery during their treatment course (38% versus 70%, p < 0.001) and more likely to undergo radiation (77% versus 52%, p < 0.001), but no more likely to receive chemotherapy (p = 0.34). If they did undergo surgery, older women were less likely to have a pelvic lymph node dissection performed (41% versus 61%, p = 0.04), though the rate of positive pelvic lymph nodes was not different (p = 0.80). Overall survival was decreased in the older cohort (p < 0.001). A multivariate model identified age > 65 (HR 1.76, 95%CI 1.30-2.40), stage (HR 2.77, 95%CI 2.40-3.21), and ever undergoing surgery (HR 0.60, 95%CI 0.44-0.82) as independently associated with overall survival. CONCLUSIONS:Women over age 65 with cervical cancer are less likely to undergo surgical management and were observed to have a decreased overall survival, even when controlling for use of surgery and stage of disease.

BACKGROUND:The American Society of Clinical Oncology recommends that patients with advanced cancer receive dedicated palliative care services early in their disease course. This investigation serves to understand how palliative care services are utilized for ovarian cancer patients in a tertiary referral center. METHODS:We conducted a retrospective review of women treated for ovarian cancer at our institution from 2010 through 2015. Clinical variables included presence and timing of palliative care referral. Data were correlated utilizing univariable and multivariable parametric and non-parametric testing, and survivals were analyzed using the Kaplan-Meier method and cox-proportional hazard models. RESULTS:We identified 391 women treated for ovarian cancer, of whom 68% were diagnosed with stage III or IV disease. Palliative care referral was utilized in 28% in the outpatient (42%) and inpatient (58%) settings. Earlier use of referral was observed in those who never underwent surgical cytoreduction or had interval cytoreductive surgery (p < 0.001). Palliative care referral was independently associated with advanced stage (OR 1.7, p = 0.02), recurrence (OR 2.0, p = 0.002) and hospice referral (OR 6.0, p < 0.001). In 38% of women referral occurred within 30 days of death, and 17% within one week of death. Outpatient initial consultation was associated with an unadjusted 1 year overall survival benefit (p < 0.01) compared to inpatient consultation. CONCLUSIONS:The outcomes in this study suggest a late use of palliative care that is reactionary to patient needs and not a routine component of ovarian cancer care as national guidelines recommend.
