RESUMEN

OBJECTIVE: Histopathologic characteristics after neoadjuvant chemotherapy (NACT) may correlate with outcome. This study evaluates histopathologic features after immunotherapy and NACT/bevacizumab, and associated clinical outcomes. METHODS: Evaluable tissue from IMagyn050/GOG3015/ENGOT-ov39 patients from prespecified anatomic sites from interval cytoreductive surgery (ICS) after NACT/bevacizumab plus atezolizumab/placebo underwent central histopathologic scoring and analyzed with clinical outcomes. RESULTS: The predefined population had 243 evaluable NACT patients, with 48.1% tumors being PD-L1-positive. No statistically significant differences in PFS (16.9 months vs. 19.2 months, p = 0.21) or OS (41.5 months vs. 45.1 months, p = 0.67) between treatment arms were seen. Substantial residual tumor (RT) (3+) was identified in 26% atezolizumab vs. 24% placebo arms (p = 0.94). Most showed no (1+) necrosis (82% vs. 96%, respectively, p = 0.69), moderate (2+) to severe (3+) fibrosis (71% vs. 75%, respectively, p = 0.82), and extensive (2+) inflammation (53% vs. 47% respectively, p = 0.48). No significant histopathologic differences were identified by tissue site or by arm. Multivariate analyses showed increased risk for progression with moderate and substantial RT (13.6 mon vs. 21.1 mon, hazard ratio 2.0, p < 0.01; 13.6 mon vs. 21.1 mon, HR 1.9, p < 0.01, respectively); but decreased risk for death with extensive inflammation (46.9 mon vs. 36.3 mon, HR 0.65, p = 0.02). Inflammation also correlated with greater likelihood of response to NACT/bevacizumab plus immunotherapy (odds ratio 2.9, p < 0.01). Modeling showed inflammation as a consistent but modest predictor for OS. CONCLUSIONS: Detailed histologic assessment of ICS specimens appear to identify characteristics, such as inflammation and residual tumor, that may provide insight to certain clinical outcomes. Future work potentially leveraging emerging tools may provide further insight into outcomes.

RESUMEN

The human papilloma virus (HPV) vaccine is the world's first proven and effective vaccine to prevent cancers in males and females when administered pre-exposure. Like most of the US, barely half of Vermont teens are up-to-date with the vaccination, with comparable deficits in New Hampshire and Maine. The rates for HPV vaccine initiation and completion are as low as 33% in rural New England. Consequently, there is a compelling responsibility to communicate its importance to unvaccinated teenagers before their risk for infection increases. Messaging in rural areas promoting HPV vaccination is compromised by community-based characteristics that include access to appropriate medical care, poor media coverage, parental and peer influence, and skepticism of science and medicine. Current strategies are predominantly passive access to literature and Internet-based information. Evidence indicates that performance-based messaging can clarify the importance of HPV vaccination to teenagers and their parents in rural areas. Increased HPV vaccination will significantly contribute to the prevention of a broadening spectrum of cancers. Reducing rurality-based inequities is a public health priority. Development of a performance-based peer-communication intervention can capture a window of opportunity to provide increasingly effective and sustained HPV protection. An effective approach can be partnering rural schools and regional health teams with a program that is nimble and scalable to respond to public health policies and practices compliant with COVID-19 pandemic-related modifications on physical distancing and interacting in the foreseeable future.

RESUMEN

BACKGROUND: As ovarian cancer treatment shifts to provide more complex aspects of care at high-volume centers, almost a quarter of patients, many of whom reside in rural counties, will not have access to those centers or receive guideline-based care. OBJECTIVE: To explore the association between proximity of residential zip code to a high-volume cancer center with mortality and survival for patients with ovarian cancer. METHODS: The National Cancer Database was queried for cases of newly diagnosed ovarian cancer between January 2004 and December 2015. Our predictor of interest was distance traveled for treatment. Our primary outcomes were 30-day mortality, 90-day mortality, and overall survival. The effect of treatment on survival was analyzed with the Kaplan-Meier method. Multiple logistic regression for binary outcomes and Cox proportional hazards regression for overall survival were used to assess the effect of distance on outcome, controlling for potential confounding variables. RESULTS: A total of 115 540 patients were included. There was no statistically significant difference in 30- or 90-day mortality among any of the travel distance categories. A statistically significant decrease in 30-day re-admission was found among patients who lived further away from the treating facility. A total of 105 529 patients were available for survival analysis, and survival curves significantly differed between distance strata (p<0.0001). The adjusted regression models demonstrated increased long-term mortality in patients who lived farther away from the treating facility after controlling for potential confounding. CONCLUSION: Although 30- and 90-day mortality do not differ by travel distance, worse survival is observed among women living >50 miles from a high-volume treatment facility. With a national policy shift toward centralization of complex care, a better understanding of the impact of distance on survival in patients with ovarian cancer is crucial. Our findings inform the practice of healthcare delivery, especially in rural settings.

RESUMEN

BRCA1 and BRCA2 pathogenic variant carriers have a high lifetime risk of developing breast and ovarian malignancies. Given the risks and significant ramifications of undergoing risk-reducing surgeries, many pathogenic variant carriers unaffected by cancer (previvors) struggle with family planning and reproductive decision making. The objective of this study was to determine the attitudes and practices of BRCA1 and BRCA2 pathogenic variant carriers with respect to family planning decision making. A cross-sectional survey was conducted of BRCA1 and BRCA2 previvors at four Northeastern medical centers. The survey was administered electronically via email using REDCap. The survey included demographic information as well as questions about genetic testing, prophylactic surgeries, family planning, and partnering. Data were analyzed with Fisher's exact tests and t tests. The survey was completed by 139 of 422 BRCA1 and BRCA2 pathogenic variant carriers (response rate 33%). Thirteen were excluded from analysis due to self-reported cancer history. Of the remaining 126, 21 (16.7%) were male and 105 (83.3%) were female. Female participants <35 years old at the time of genetic testing were significantly more likely than those 35 or greater to report feeling urgency to have a family after finding out about their BRCA1 and BRCA2 pathogenic variant (p < 0.0001). Younger women also reported their genetic status had a stronger impact on their romantic relationships (p = 0.029). Men were significantly more likely to report that they felt no urgency to have a family compared to women (p < 0.0001). Our study reflects the complex decision making for previvors and the intricacies of family planning in this population. Providers can use this knowledge as a guide to counsel patients about reproductive options.

RESUMEN

OBJECTIVE: To evaluate the use of a portable, rechargeable colposcope combined with human papillomavirus (HPV) testing, as compared with HPV testing alone, for screening of cervical cancer and pre-cancerous lesions. METHODS: This was a cross-sectional study among 488 women in Baoshan County, Yunnan. The women underwent HPV testing followed by Gynocular portable colposcopy with visual inspection with acetic acid. Obvious lesions were biopsied. If portable colposcopy testing was negative but HPV testing was positive, the women underwent follow-up testing with thin-prep cytology and traditional colposcopy. Cervical biopsies were performed for any abnormalities. Histopathology was followed up with diagnosis and treatment. RESULTS: Among 488 women screened with portable colposcopy, 24 women underwent biopsy based on positive colposcopy screening. Of these 24 women, three were HPV positive and 21 were HPV negative. Five women had cervical intra-epithelial neoplasia (CIN) I and one had advanced cervical cancer. Forty-six women tested positive for HPV. Three of these women had screened positive on preliminary colposcopy, with one positive for CIN III/squamous cell carcinoma and one woman with CIN I. Forty-three women underwent follow-up testing with thin-prep cytology. Two women had atypical squamous cells of undetermined significance and five had low-grade squamous intra-epithelial lesions and were biopsied; three women had CIN I, one had CIN II and one had CIN III. HPV testing and portable colposcopy was more sensitive but slightly less specific than portable colposcopy or HPV testing alone. CONCLUSION: While HPV testing has high sensitivity and specificity for the detection of pre-cancerous and cancerous lesions and portable colposcopy has lower specificity, both methods of detection have low positive predictive value and high negative predictive value. In tandem, HPV testing and portable colposcopy had higher sensitivity for detection among women who underwent biopsies. In clinical practice, portable colposcopy was an effective, easy and affordable tool to transport to villages where cytology is not currently feasible.

RESUMEN

OBJECTIVE: The World Health Organization (WHO)'s cervical cancer screening guidelines for limited-resource settings recommend sequential screening followed by same-day treatment under a "screen-and-treat" approach. We aimed to (1) assess feasibility and clinical outcomes of screening HIV-positive and HIV-negative Cameroonian women by pairing visual inspection with acetic acid and Lugol's iodine enhanced by digital cervicography (VIA/VILI-DC) with careHPV, a high-risk human papillomavirus (HR-HPV) nucleic acid test designed for low-resource settings; and (2) determine persistence of HR-HPV infection after one-year follow-up to inform optimal screening, treatment, and follow-up algorithms. METHODS: We co-tested 913 previously unscreened women aged ≥30years and applied WHO-recommended treatment for all VIA/VILI-DC-positive women. Baseline prevalence of HR-HPV and HIV were 24% and 42%, respectively. RESULTS: On initial screen, 44 (5%) women were VIA/VILI-DC-positive, of whom 22 had HR-HPV infection, indicating 50% of women screened false-positive and would have been triaged for unnecessary same-day treatment. VIA/VILI-DC-positive women with HIV infection were three times more likely to be HR-HPV-positive than HIV-negative women (65% vs. 20%). All women positive for either VIA/VILI-DC or HR-HPV (n=245) were invited for repeat co-testing after one year, of which 136 (56%) returned for follow-up. Of 122 women who were HR-HPV-positive on initial screen, 60 (49%) re-tested negative, of whom 6 had received treatment after initial screen, indicating that 44% of initially HR-HPV-positive women spontaneously cleared infection after one year without treatment. Women with HIV were more likely to remain HR-HPV-positive on follow-up than HIV-negative women (61% vs. 22%, p<0.001). Treatment was offered to all VIA/VILI-DC positive women on initial screen, and to all women screening VIA/VILI-DC or HR-HPV positive on follow-up. CONCLUSIONS: We found careHPV co-testing with VIA/VILI-DC to be feasible and valuable in identifying false-positives, but careHPV screening-to-result time was too long to inform same-day treatment.

RESUMEN

BACKGROUND: Cervical cancer screening is one of the most effective cancer prevention strategies, but most women in Africa have never been screened. In 2007, the Cameroon Baptist Convention Health Services, a large faith-based health care system in Cameroon, initiated the Women's Health Program (WHP) to address this disparity. The WHP provides fee-for-service cervical cancer screening using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC), prioritizing care for women living with HIV/AIDS. They also provide clinical breast examination, family planning (FP) services, and treatment for reproductive tract infection (RTI). Here, we document the strengths and challenges of the WHP screening program and the unique aspects of the WHP model, including a fee-for-service payment system and the provision of other women's health services. METHODS: We retrospectively reviewed WHP medical records from women who presented for cervical cancer screening from 2007-2014. RESULTS: In 8 years, WHP nurses screened 44,979 women for cervical cancer. The number of women screened increased nearly every year. The WHP is sustained primarily on fees-for-service, with external funding totaling about $20,000 annually. In 2014, of 12,191 women screened for cervical cancer, 99% received clinical breast exams, 19% received FP services, and 4.7% received treatment for RTIs. We document successes, challenges, solutions implemented, and recommendations for optimizing this screening model. CONCLUSION: The WHP's experience using a fee-for-service model for cervical cancer screening demonstrates that in Cameroon VIA-DC is acceptable, feasible, and scalable and can be nearly self-sustaining. Integrating other women's health services enabled women to address additional health care needs. IMPLICATION FOR PRACTICE: The Cameroon Baptist Convention Health Services Women's Health Program successfully implemented a nurse-led, fee-for-service cervical cancer screening program using visual inspection with acetic acid-enhanced by digital cervicography in the setting of a large faith-based health care system in Cameroon. It is potentially replicable in many African countries, where faith-based organizations provide a large portion of health care. The cost-recovery model and concept of offering multiple services in a single clinic rather than stand-alone "silo" cervical cancer screening could provide a model for other low-and-middle-income countries planning to roll out a new, or make an existing, cervical cancer screening services accessible, comprehensive, and sustainable.

RESUMEN

Intraoperative frozen section (IFS) on endometrial cancer is an invaluable skill for pathologists-in-training to master. Within limited time constraints, pathologists are expected to determine tumor type, grade, and depth of myometrial invasion. During their training, pathology residents gradually gain experience in handling the majority of cases. However, significant errors can still be seen among senior level trainees. We aimed to improve training effectiveness by evaluating our trainees' performance, identifying common errors, and recommending focused curriculum. Twenty-two residents [postgraduate year (PGY)-1-PGY-4] performed 260 IFS during a 4-yr period. We compared their independent IFS diagnoses with final diagnoses. Overall resident IFS accuracy was 73%. Accuracy for tumor type and depth of myometrial invasion was 80% and 93%, respectively. Two thirds of errors were due to sampling with the rest because of interpretation. Major deficiencies lay in recognizing high-risk histologic types (serous, clear cell, sarcoma) and unconventional myometrial invasion patterns (MELF, adenoma malignum, and adenomyosis-like). Resident IFS errors would theoretically result in suboptimal staging for 32 (12%) patients and unnecessary staging for 1 (0.4%). Overall IFS performance improved as training level increased (76% accuracy for PGY-1 accompanied by PGY-5; 59% for PGY-2; 74% for PGY-3; and 86% for PGY-4). We recommend a dedicated curriculum targeting these difficult yet clinically important entities through review literature and a collection of classic cases demonstrating the diverse morphology variations. Implementing such focused training would greatly improve our trainees' competence on IFS, preparing them to handle a wide variety of cases and situations in future practice.

RESUMEN

OBJECTIVE: The World Health Organization recommends visual inspection with acetic acid (VIA) for cervical cancer screening in resource-limited settings. In Cameroon, we use digital cervicography (DC) to capture images of the cervix after VIA. This study evaluated interobserver agreement of DC results, compared DC with histopathologic results, and examined interobserver agreement among screening methods. METHOD: Three observers, blinded to each other's interpretations, evaluated 540 DC photographs as follows: (1) negative/positive for acetowhite lesions or cancer and (2) assigned a presumptive diagnosis of histopathologic lesion grade in the 91 cases that had a histopathologic diagnosis. Observer A was the actual screening nurse; B, a reproductive health nurse; C, a gynecologic oncologist; and D, the histopathologic diagnosis. We compared inter-rater agreement of DC impressions among observers A, B, and C, and with D, with Cohen kappas. RESULTS: For interpretations of DC, (negative/positive) strengths of agreement of paired observers were the following: A/B, moderate [K, 0.54; 95% confidence interval (CI), 0.47-0.61], A/C, fair (K, 0.37; 95% CI, 0.29-0.44), and B/C, moderate (K, 0.45; 95% CI, 0.37-0.53). For presumptive pathologic grading, strengths of agreement for weighted Ks were as follows: A/B, moderate (K, 0.42; 95% CI, 0.28-0.56); A/C, fair (K, 0.33; 95% CI, 0.20-0.46); B/C, fair (K, 0.54; 95% CI, 0.40-0.67); A/D, moderate (K, 0.59; 95% CI, 0.45-0.74); B/D, moderate (K, 0.58; 95% CI, 0.46-0.70); and C/D, moderate (K, 0.50; 95% CI, 0.37-0.63). CONCLUSIONS: Interobserver agreement of DC interpretations was mostly moderate among the 3 observers, between them and histopathology, and comparable to that of other visual-based screening methods, i.e., VIA, cytology, or colposcopy.

RESUMEN

OBJECTIVE: Alterations in the PI3K pathway are prevalent in endometrial cancer due to PIK3CA mutation and loss of PTEN. We investigated the anti-tumor activity of the PI3K inhibitor NVP BKM-120 (BKM) as a single agent and in combination with standard cytotoxic chemotherapy in a human primary endometrial xenograft model. METHODS: NOD/SCID mice bearing xenografts of primary human tumors with and without PIK3CA gene mutations were divided into two and four arm cohorts with equivalent tumor volumes. BKM was administered alone and in combination with paclitaxel and carboplatin (P/C) and endometrial xenograft tumor volumes were assessed. Tumors from the BKM, P/C, P/C+BKM and vehicle treated mice were processed for determination of PI3K/AKT/mTOR pathway activation. RESULTS: In both single agent experiments, BKM resulted in significant tumor growth suppression starting at days 5-10 compared to the linear growth observed in vehicle treated tumors (p<0.04 in all experiments). Tumor resurgence manifested between days 14 and 25 (p<0.03). When BKM was combined with P/C, this resistance pattern failed to develop in three separate xenograft lines (p<0.05). Synergistic tumor growth suppression (p<0.05) of only one xenograft tumor with no detected PIK3CA mutation was observed. Acute treatment with BKM led to a decrease in pAKT levels. CONCLUSION: Independent of PIK3CA gene mutation, BKM mediated inhibition of the PI3K/AKT/mTOR pathway in endometrial tumors precludes tumor growth in a primary xenograft model. While a pattern of resistance emerges, this effect appears to be mitigated by the addition of conventional cytotoxic chemotherapy.

RESUMEN

STUDY OBJECTIVE: To describe the feasibility, safety, and outcomes of women with stage I cervical cancer treated with laparoendoscopic single-site surgery radical hysterectomy (LESS-RH). DESIGN: A retrospective descriptive study (Canadian Task Force classification III). SETTING: Multiple academic teaching hospitals. PATIENTS: Women with Fédération Internationale de Gynécologie et d'Obstétrique FIGO stage IA1 to IB1 cervical cancer. INTERVENTIONS: LESS-RH as the primary therapy for cervical cancer performed by a gynecologic oncologist with expertise in LESS. A multichannel, single-port access device; a flexible-tipped 5-mm laparoscope; and a multifunctional instrument were used in all cases. Clinicopathologic, surgical, and perioperative outcomes were analyzed. MEASUREMENTS AND MAIN RESULTS: Twenty-two women were identified in whom a LESS-RH was attempted; 20 (91%) successfully underwent the procedure, including 19 in whom pelvic lymphadenectomy (PLND) was completed. Of the 2 converted procedures, 1 patient underwent 2-port laparoscopy secondary to truncal obesity, and 1 patient underwent conversion to laparotomy secondary to external iliac vein laceration during PLND. The median age and body mass index were 46 years and 23.3 kg/m(2), respectively. The median number of pelvic lymph nodes removed was 22. One patient experienced an intraoperative complication, and no patient required reoperation. The margins of excision were negative. One patient with 2 positive pelvic nodes and 1 patient with microscopic parametrial disease received adjuvant chemosensitized radiation; 3 additional patients received adjuvant radiation therapy secondary to an intermediate risk for recurrence. After a median follow up of 11 months, no recurrences were detected. CONCLUSION: LESS-RH/PLND is feasible and safe for select patients with stage I cervical cancer. Larger studies are needed to confirm whether the increased technical difficulty of this procedure justifies its use in routine gynecologic oncology practice.

RESUMEN

PURPOSE: Evaluation by a gynecologic oncologist (GO) is associated with improved clinical outcomes for patients with gynecologic cancers, yet little is known about health care factors that influence patients' referrals to GO. METHODS: Medical records of 50 consecutive new patients seen in GO clinics at each of six referral centers across the United States were reviewed. Patient and disease characteristics were collected along with referral indication, evaluation and referral dates, diagnostic procedures, provider specialties, and zone improvement plan (ZIP) code of up to three referring providers per patient. The primary outcome was interval between first evaluation and referral. Univariate associations were evaluated with Chi-square and Wilcoxon rank-sum tests and multivariable associations with negative binomial regression models. Secondary outcome was prolonged time to GO referral, defined as greater than the 75th percentile. Logistic regression was used for multivariable modeling. RESULTS: Three hundred patient records were analyzed. The median time from first health care encounter to referral was 15 days (IQR, 5-43). The mean distance from residence to GO was 39.8 miles (standard deviation, 53.8). Seventy-one percent of GO referrals were initiated by obstetrician-gynecologists, 9% by family physicians, and 6% internists. Presentation-to-referral interval was 76% shorter for patients evaluated by an emergency medicine clinician (exp(Beta), 0.24; 95% CI, 0.11 to 0.53; P < .001). Public insurance was associated with 1.47 times longer time to referral compared with private insurance (exp(Beta), 1.47; 95% CI, 1.05 to 2.04; P = .001). Residents of nonmetropolitan ZIP codes were less likely to have prolonged time to referral (odds ratio [OR], 0.288; P = .017). Distance from residence to GO (per 10 miles) increased the likelihood of prolonged time to referral (OR, 1.10; P = .010). CONCLUSION: Interventions are needed to improve recognition and referral of patients for gynecologic oncology evaluation. Community outreach and engagement with obstetrician-gynecologists should be prioritized to improve times to referral.

RESUMEN

Objective: To determine the utilization of risk-reducing strategies and screening protocols for ovarian cancer in female BRCA1/2 carriers. Methods: This study was a sub-analysis of female participants from a larger multicenter, cross-sectional survey of BRCA1/2 mutation carriers unaffected by cancer. The questionnaire was administered electronically via email at four institutions located in the northeast United States. Data were analyzed with Fisher's exact test. Results: The survey was completed by 104 female BRCA mutation carriers. BRCA subtypes included 54.3% BRCA2, 41.0% BRCA1, and 2.9% both. The age at which patients underwent genetic testing varied 21.2% were 18-24 years, 25.0% were 25-34 years, 29.8% were 35-44 years, and 24.0% were 45 years or older. Nearly, all respondents (97.1%) reported that a provider had discussed risk-reducing surgeries. Of the 79 females who underwent genetic testing before 45 years of age, 53.2% reported that a health care provider recommended taking combined oral contraceptive pills (COCs) to reduce their risk of ovarian cancer, and, of these women, 88.1% chose to use them. COCs were offered at higher rates among women who were younger at the age of genetic testing (18-24: 86%, 25-34: 62%, 35-44: 23%; p < 0.0001). Approximately half (55.8%) of the respondents reported having been offered increased screening for possible early detection of ovarian cancer, of which 81.0% chose to undergo screening. The majority utilized a combination of transvaginal ultrasound and serum CA125 measurements. There were no differences observed in screening utilization based on BRCA mutation type. Conclusion: In our cohort of female BRCA mutation carriers, risk-reducing surgery was offered to almost all women, whereas only half were offered risk-reducing medication and/or increased screening. Further investigation is needed to identify barriers to the utilization of risk-reducing strategies among this high-risk population.

RESUMEN

Genomic tumor testing (GTT) is an emerging technology aimed at identifying variants in tumors that can be targeted with genomically matched drugs. Due to limited resources, rural patients receiving care in community oncology settings may be less likely to benefit from GTT. We analyzed GTT results and observational clinical outcomes data from patients enrolled in the Maine Cancer Genomics Initiative (MCGI), which provided access to GTTs; clinician educational resources; and genomic tumor boards in community practices in a predominantly rural state. 1603 adult cancer patients completed enrollment; 1258 had at least one potentially actionable variant identified. 206 (16.4%) patients received a total of 240 genome matched treatments, of those treatments, 64% were FDA-approved in the tumor type, 27% FDA-approved in a different tumor type and 9% were given on a clinical trial. Using Inverse Probability of Treatment Weighting to adjust for baseline characteristics, a Cox proportional hazards model demonstrated that patients who received genome matched treatment were 31% less likely to die within 1 year compared to those who did not receive genome matched treatment (HR: 0.69; 95% CI: 0.52-0.90; p-value: 0.006). Overall, GTT through this initiative resulted in levels of genome matched treatment that were similar to other initiatives, however, clinical trials represented a smaller share of treatments than previously reported, and "off-label" treatments represented a greater share. Although this was an observational study, we found evidence for a potential 1-year survival benefit for patients who received genome matched treatments. These findings suggest that when disseminated and implemented with a supportive infrastructure, GTT may benefit cancer patients in rural community oncology settings, with further work remaining on providing genome-matched clinical trials.

RESUMEN

BACKGROUND: The purpose of this study is to examine changes over time in survival for African American (AA) and white women diagnosed with cervical cancer (CC). METHODS: Surveillance, Epidemiology, and End Results (SEER) Program data from 1985 to 2009 were used for this analysis. Racial differences in survival were evaluated between African American (AA) and white women. Kaplan-Meier and Cox proportional hazards survival methods were used to assess differences in survival by race at 5-year intervals. RESULTS: The study sample included 23,368 women, including 3886 (16.6%) who were AA and 19,482 (83.4%) who were white. AA women were older (51.4 versus 48.9 years; P<.001) and had a higher rate of regional (38.3% versus 31.8%; P<.001) and distant metastasis (10.7% versus 8.7%; P<.001). AA less frequently received cancer-directed surgery (32.4% versus 46%; P<.001), and more frequently radiotherapy (36.3% versus 26.4%; P<.001). Overall, AA women had a hazard ratio (HR) of 1.41 (95% confidence interval=1.32-1.51) of cervical cancer (CC) mortality compared with whites. Adjusting for SEER registry, marital status, stage, age, treatment, grade, and histology, AA women had an HR of 1.13 (95% confidence interval=1.05-1.22) of CC-related mortality. After adjusting for the same variables, there was a significant difference in CC-specific mortality between 1985 to 1989 and 1990 to 1994, but not after 1995. CONCLUSIONS: After adjusting for race, SEER registry, marital status, stage, age, treatment, grade, and histology, there was a significant difference in CC-specific mortality between 1985 to 1989 and 1990 to 1994, but not after 1995.

RESUMEN

OBJECTIVE: Hospital readmissions are common, costly and increasingly viewed as adverse events. In gynecologic oncology, data on readmissions are limited. The goal of this study was to examine the patient, treatment and discharge factors associated with unplanned readmission after cytoreductive surgery. METHODS: We identified all patients with stages II-IV ovarian cancer who underwent surgical cytoreduction at our institution between 2003 and 2011. A retrospective chart review was performed, and clinical variables were extracted. Utilizing linear and logistic regression, these clinical variables were correlated with risk of readmission. RESULTS: A total of 460 patients were included in the analysis, with the majority having a stage IIIC high grade serous cancer. Optimal cytoreduction (<1.0 cm residual disease) was obtained in 368 patients (81%), and 233 patients (50%) underwent at least one radical procedure. Perioperative complications were observed in 148 patients (32%). A large proportion of our cohort was discharged to rehabilitation facilities (12%) or with a visiting nurse (38%). Fifty five patients (12%) were readmitted within 30 days. On multivariate logistic regression, reoperation and perioperative cardiopulmonary event were the only factors associated with readmission (OR=3.2, 95% CI=1.7-6.0). Discharge home with ancillary services was not protective against readmission, even when controlling for perioperative complications (OR=1.18, 95% CI=0.53-2.64). CONCLUSIONS: Readmission after surgical cytoreduction affected 12% of our population. Multivariate analyses suggested perioperative complications, particularly reoperation and cardiopulmonary event, placed the patient at the greatest risk. Age, comorbidities, surgical radicality and discharge with visiting nurse services/rehabilitation facility did not affect the likelihood of readmission.

RESUMEN

OBJECTIVE: Primary debulking surgery (PDS) has historically been the standard treatment for advanced ovarian cancer. Recent data appear to support a paradigm shift toward neoadjuvant chemotherapy with interval debulking surgery (NACT-IDS) for a subset of women with advanced ovarian cancer. It remains unresolved whether NACT-IDS increases the risk of platinum resistance. We compared response to chemotherapy in patients that received NACT-IDS vs. PDS. METHODS: From our Cancer Registry database we identified patients with stages IIIC and IV epithelial ovarian cancer who underwent treatment from January, 2005 to December, 2010. Standard univariate analyses were performed, as were multivariable analysis with logistic regression. The Kaplan-Meier method was used to generate survival data. RESULTS: The study population consisted of 425 patients, 95 (22.3%) underwent NACT-IDS and 330 (77.6%) PDS. After the initial platinum-based chemotherapy, 42 (44.2%) women in the NACT-IDS group were considered to have platinum resistant disease, compared to 103 (31.2%) in the PDS group (P=0.01). When multivariate logistic regression was used to control for factors independently associated with platinum resistance, NACT-IDS was no longer associated with an initial increased risk. However, in women that had a recurrence and were retreated with platinum-based chemotherapy, 32 (88.8%) in the NACT-IDS group had developed a recurrence within six months and were considered platinum resistant, compared to 62 (55.3%) in the PDS (P<0.001). CONCLUSION: In women with EOC that have a recurrence and are treated again with platinum-based chemotherapy, NACT-IDS appears to increase the risk of platinum resistance.

RESUMEN

OBJECTIVE: The aims of this study are to determine if outcomes of patients with ovarian carcinosarcoma (OCS) differ from women with high grade papillary serous ovarian carcinoma when compared by stage as well as to identify any associated clinico-pathologic factors. METHODS: The Surveillance, Epidemiology, and End Results (SEER) Program data for all 18 registries from 1998 to 2009 was reviewed to identify women with OCS and high grade papillary serous carcinoma of the ovary. Demographic and clinical data were compared, and the impact of tumor histology on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazard model. RESULTS: The final study group consisted of 14,753 women. 1334 (9.04%) had OCS and 13,419 (90.96%) had high grade papillary serous carcinoma of the ovary. Overall, women with OCS had a worse five-year, disease specific survival rate, 28.2% vs. 38.4% (P<0.001). This difference persisted for each FIGO disease stages I-IV, with five year survival consistently worse for women with OCS compared with papillary serous carcinoma. Over the entire study period, after adjusting for histology, age, period of diagnosis, SEER registry, marital status, stage, surgery, radiotherapy, lymph node dissection, and history of secondary malignancy after the diagnosis of ovarian cancer, carcinosarcoma histology was associated with decreased cancer-specific survival. CONCLUSIONS: OCS is associated with a poor prognosis compared to high grade papillary serous carcinoma of the ovary. This difference was noted across all FIGO stages.

RESUMEN

OBJECTIVE: The purpose of this study was to examine changes over time in survival for African-American (AA) and white women diagnosed with squamous cell carcinoma of the vulva. STUDY DESIGN: The Surveillance, Epidemiology, and End Results (SEER) Program for 1973-2009 was used for this analysis. We evaluated racial differences in survival between AA and white women. Kaplan-Meier and Cox proportional hazards survival methods were used to assess differences in survival by race by decade of diagnosis. RESULTS: The study sample included 5867 women, including 5379 whites (91.6%) and 488 AA (8.3%). AA women were younger (57 vs 67 years; P < .001) and had a higher rate of distant metastasis (6.1% vs 3.7%; P < .001). AA women had surgery less frequently (84.2% vs 87.6%; P = .03) and more frequently radiotherapy (24.2% vs 20.6%; P < .001). AA women had a hazard ratio (HR) of 0.84 (95% confidence interval [CI], 0.74-0.95) of all-cause mortality and 0.66 (95% CI, 0.53-0.82) of vulvar cancer mortality compared with whites. Adjusting for SEER Registry, marital status, stage, age, surgery, radiotherapy, grade, lymph node status, and decade, AA women had an HR of 0.67 (95% CI, 0.53-0.84) of vulvar cancer-related mortality compared with whites. After adjusting for the same variables, there was a significant difference in survival between AA and whites in the periods of 1990-1999 (HR, 0.62; 95% CI, 0.41-0.95) and 2000-2009 (HR, 0.46; 95% CI, 0.30-0.72) but not earlier. CONCLUSION: AA presented at a significantly younger age compared with white women and had better survival compared with whites.

RESUMEN

Cervical cancer is both preventable and curable, yet it remains one of the leading causes of mortality in women worldwide. Approximately 88% of cervical cancer cases are diagnosed in low-resource countries, yet very few resources are allocated to prevention and treatment programs. In fact, it is estimated that only 5% of women in low-resources countries are screened appropriately for cervical cancer. Cytology-based programs are not feasible because of lack of healthcare infrastructure and cost, thus alternative methods of cancer screening, such as visual inspection with acetic acid and HPV-DNA testing, have been intensively studied and are reviewed in this article.
