RESUMEN

Our objective was to assess gynecologic cancer survivor preferences for telehealth cancer care. Gynecologic cancer survivors participating in a prospective cohort study were invited to complete a cross-sectional survey regarding their experience with and preferences for telehealth. Of 188 participants, 48.9% had undergone a telehealth visit since March 2020, and 53.7% reported a preference for exclusively in-person visits for their cancer care and surveillance. Furthermore, 80.5% of participants were satisfied with the telehealth care they received and 54.8% would recommend telehealth services to patients with similar conditions. Most participants thought a physical examination was critical to detecting recurrence, and concern that their provider may miss something during telehealth visits was greater among those who preferred in-person visits. With many gynecologic cancer survivors preferring in-person care, building a future care model that includes telehealth elements will require adaptations, careful evaluation of patient concerns, as well as patient education on telehealth.

RESUMEN

Early-career female faculty, both physician scientists and basic researchers, have disproportionately experienced negative professional, financial, and personal consequences associated with the novel coronavirus disease 2019 (COVID-19) pandemic. This career phase represents a critical time for establishing a network of mentors and collaborators, demonstrating professional independence, and balancing new teaching, research, and service duties while simultaneously navigating personal and familial responsibilities. Persistent gender inequality perpetuated by adherence to traditional gender roles place early-career women faculty at a further disadvantage. Women in academic medicine and research do not attain promotion, leadership positions, and other established markers of success at the same rate as their male counterparts. This disparity was the impetus for the creation of a Recruitment and Retention action group within the Center for Women in Medicine and Science (CWIMS) at the University of Minnesota Medical School (UMN). This perspective piece is written from the viewpoint of a group of female-identifying early-career faculty participating in a career development program for early-stage and newly appointed faculty at UMN, sponsored by the Recruitment and Retention CWIMS action group and our Office of Faculty Affairs. We describe areas of stress exacerbated by the COVID-19 pandemic: work, financial, and work-life well-being, and propose an adapted diversity, equity and inclusion (DEI) model to guide the response to future challenges within a faculty competency framework. We offer recommendations based on the DEI-competency framework, including opportunities for lasting positive change that can emerge from this challenging moment of our collective history.

RESUMEN

PURPOSE: To provide expert guidance to clinicians and policymakers in three resource-constrained settings on diagnosis and staging of adult women with ovarian masses and treatment of patients with epithelial ovarian (including fallopian tube and primary peritoneal) cancer. METHODS: A multidisciplinary, multinational ASCO Expert Panel reviewed existing guidelines, conducted a modified ADAPTE process, and conducted a formal consensus process with additional experts. RESULTS: Existing sets of guidelines from eight guideline developers were found and reviewed for resource-constrained settings; adapted recommendations from nine guidelines form the evidence base, informing two rounds of formal consensus; and all recommendations received ≥ 75% agreement. RECOMMENDATIONS: Evaluation of adult symptomatic women in all settings includes symptom assessment, family history, and ultrasound and cancer antigen 125 serum tumor marker levels where feasible. In limited and enhanced settings, additional imaging may be requested. Diagnosis, staging, and/or treatment involves surgery. Presurgical workup of every suspected ovarian cancer requires a metastatic workup. Only trained clinicians with logistical support should perform surgical staging; treatment requires histologic confirmation; surgical goal is staging disease and performing complete cytoreduction to no gross residual disease. In first-line therapy, platinum-based chemotherapy is recommended; in advanced stages, patients may receive neoadjuvant chemotherapy. After neoadjuvant chemotherapy, all patients should be evaluated for interval debulking surgery. Targeted therapy is not recommended in basic or limited settings. Specialized interventions are resource-dependent, for example, laparoscopy, fertility-sparing surgery, genetic testing, and targeted therapy. Multidisciplinary cancer care and palliative care should be offered.Additional information can be found at www.asco.org/resource-stratified-guidelines. It is ASCO's view that health care providers and health care system decision makers should be guided by the recommendations for the highest stratum of resources available. The guideline is intended to complement but not replace local guidelines.

RESUMEN

BACKGROUND: Ovarian cancer is the third leading cause of cancer death among women in Ethiopia, with about 2,550 diagnosed cases and 2,000 deaths each year. The incidence and mortality rates of this disease have been increasing in Ethiopia and other parts of sub-Saharan Africa over the past decades because of changing lifestyle and reproductive factors. In this study, we describe the clinical characteristics, treatment patterns, and survival of patients with ovarian cancer in Ethiopia. MATERIALS AND METHODS: This retrospective cohort study included 485 patients diagnosed between January 2009 and October 2015 at Addis Ababa University Hospital, Zewditu Memorial Hospital, or registered in the Addis Ababa population-based cancer registry. Follow-up data were obtained via telephone. Primary endpoint was all-cause mortality. RESULTS: The median age was 46 years (range, 11-95). The estimated 1- and 2-year overall survival rates were 78% (95% confidence interval [CI] 0.741-0.82.5) and 59% (95% CI, 0.538-0.646), respectively. Of those patients with result available (n = 423), 73.0% had epithelial cancers. Almost half were classified as Federation of Gynecology and Oncology stage III or IV (48.2%; stage available n = 201) resulting in worse outcomes (hazard ratio [HR], 2.91 [CI 0.67-12.64] and 3.03 [0.69-15.79], respectively). Four out of five patients received some form of surgery (82%), three out of five received platinum-containing chemotherapy. Patients with residual tumor after surgery (n = 83) showed worse survival outcome (HR, 2.23; 95% CI 1.08-4.49). CONCLUSION: Our study revealed substantial treatment gaps with respect to surgery and adequate chemotherapy. Higher stage, residual tumor and lack of chemotherapy impaired the outcome. Access to higher standards of ovarian cancer treatment is urgently needed in Ethiopia. IMPLICATIONS FOR PRACTICE: Ovarian cancer is often a fatal disease in high resource settings; now it is also becoming important in Ethiopia. This study included 485 women with malignant ovarian tumors treated in Addis Ababa who had a mean age of only 46 years because of the young population structure. Three quarters had the typical epithelial cancer, with half presenting with advanced stage III and IV. Improved oncologic surgery and sufficient chemotherapy could possibly improve their outcome. The relatively high proportion of women with nonepithelial cancer need adequate treatment options to have good prognosis.

RESUMEN

BACKGROUND: There is growing recognition of the worsening problem of antibiotic resistance and the need for antibiotic stewardship in low-resource settings. The aim of this study was to describe antibiotic use and antimicrobial resistance in patients undergoing surgery for peritonitis at a Rwandan referral hospital. PATIENTS AND METHODS: All surgical patients with peritonitis at a Rwandan referral hospital were enrolled. Prospective data were collected on epidemiology, clinical features, interventions, and outcomes. Antibiotic agents were prescribed and cultures were collected according to surgeon discretion. High risk for antibiotic treatment failure or death was defined as patients with severe sepsis, older than 70 years of age, tumor, or operating room delay more than 24 hours from hospital admission. Logistic regression was used to determine factors associated with high risk of antibiotic treatment failure or death. RESULTS: Over a six-month period, 280 patients underwent operation for peritonitis; 79 patients were excluded because no infectious etiology was identified at operation. Data on antibiotic usage were available for 165 patients. The most common diagnoses were intestinal obstruction (n = 43) and appendicitis (n = 36). Most patients received antibiotic agents, the most of of which being third-generation cephalosporins (n = 149; 90%) and metronidazole (n = 140; 85%). The mean duration of antibiotics was 5.1 days (range: 0-14). Overall, 80 (54%) patients were high-risk for antibiotic treatment failure or death. Risk for antibiotic treatment failure or death was associated with localized peritonitis (p = 0.001) and high American Society of Anesthesiologist score (p = 0.003). Cultures were collected from 33 patients and seven patients had an organism isolated. Escherichia coli was identified in in five surgical specimens and two 2 urine cultures. All Escherichia coli specimens showed resistance to cephalosporins. CONCLUSIONS: Broad antibiotic coverage with third-generation cephalosporins and metronidazole is common in Rwandan surgical patients with peritonitis. Areas for improvement should focus on choice and duration of antibiotic agents, tailored to underlying diagnosis and risk factors for antibiotic treatment failure or death. More data are needed on antibiotic resistance patterns to guide antimicrobial therapy.

RESUMEN

Since the initial recognition of acquired immunodeficiency syndrome (AIDS) in 1981, an increased burden of cervical cancer was identified among human immunodeficiency virus (HIV)-positive women. Introduction of antiretroviral therapy (ART) decreased risks of opportunistic infections and improved overall survival. HIV-infected women are living longer. Introduction of the human papillomavirus (HPV) vaccine, cervical cancer screening and early diagnosis provide opportunities to reduce cervical cancer associated mortality. In line with 2030 Sustainable Development Goals to reduce mortality from non-communicable diseases, increased efforts need to focus on high burden countries within sub-Saharan Africa (SSA). Despite limitations of resources in SSA, opportunities exist to improve cancer control. This article reviews advancements in cervical cancer control in HIV-positive women.

RESUMEN

In limited resource settings such as Rwanda, visual inspection with acetic acid (VIA) is the primary model for cervical cancer screening. The objective of this study was to describe clinical characteristics and outcomes for women presenting for cervical cancer screening. A prospective, observational study was conducted between September 2015 and February 2016 at Kigali University Teaching Hospital (CHUK). Women referred to the VIA clinic were enrolled and completed a semi-structured questionnaire. During the six-month study period, 150 women were enrolled and evaluated with VIA followed by colposcopy directed biopsy for VIA positive. The median age was 42 years (IQR 36-49). Only 20 (13.3%) asymptomatic women presented for screening exam, whereas 126 (84%) were symptomatic. Among symptomatic patients, more than one-third had never had a speculum exam prior to referral (n = 43). Twenty-two (14.7%) women were VIA positive, and 8 (5.3%) had lesions suspicious for cancer, while 120 (80%) were found to be VIA negative. Among women undergoing biopsy (n = 30), 11 were normal (36.7%), 5 cases showed CIN 1 (16.6%), 4 cases showed CIN 2 (13.3%), 2 cases showed CIN 3 (6.7%) and 8 were confirmed cervical cancers (26.7%). In Rwanda, VIA is the current method for cervical cancer screening. In this study, few asymptomatic patients presented for cervical cancer screening. Increasing knowledge about cervical cancer screening and expanding access are key elements to improving cervical cancer control in Rwanda.

RESUMEN

PURPOSE: Activating FGFR2 mutations have been identified in ~10% of endometrioid endometrial cancers (ECs). We have previously reported that mutations in FGFR2 are associated with shorter disease free survival (DFS) in stage I/II EC patients. Here we sought to validate the prognostic importance of FGFR2 mutations in a large, multi-institutional patient cohort. METHODS: Tumors were collected as part of the GOG 210 clinical trial "Molecular Staging of Endometrial Cancer" where samples underwent rigorous pathological review and had more than three years of detailed clinical follow-up. DNA was extracted and four exons encompassing the FGFR2 mutation hotspots were amplified and sequenced. RESULTS: Mutations were identified in 144 of the 973 endometrioid ECs, of which 125 were classified as known activating mutations and were included in the statistical analyses. Consistent with FGFR2 having an association with more aggressive disease, FGFR2 mutations were more common in patients initially diagnosed with stage III/IV EC (29/170;17%) versus stage I/II EC (96/803; 12%; p=0.07, Chi-square test). Additionally, incidence of progression (progressed, recurred or died from disease) was significantly more prevalent (32/125, 26%) among patients with FGFR2 mutation versus wild type (120/848, 14%; p<0.001, Chi-square test). Using Cox regression analysis adjusting for known prognostic factors, patients with FGFR2 mutation had significantly (p<0.025) shorter progression-free survival (PFS; HR 1.903; 95% CI 1.177-3.076) and endometrial cancer specific survival (ECS; HR 2.013; 95% CI 1.096-3.696). CONCLUSION: In summary, our findings suggest that clinical trials testing the efficacy of FGFR inhibitors in the adjuvant setting to prevent recurrence and death are warranted.

RESUMEN

PURPOSE: Gestational trophoblastic neoplasia (GTN) is a highly treatable disease, most often affecting young women of childbearing age. This study reviewed patients managed for GTN at the Butaro Cancer Center of Excellence (BCCOE) in Rwanda to determine initial program outcomes. PATIENTS AND METHODS: A retrospective medical record review was performed for 35 patients with GTN assessed or treated between May 1, 2012, and November 30, 2014. Stage, risk score, and low or high GTN risk category were based on International Federation of Gynecology and Obstetrics staging and the WHO scoring system and determined by beta human chorionic gonadotropin level, chest x-ray, and ultrasound per protocol guidelines for resource-limited settings. Pathology reports and computed tomography scans were assessed when possible. Treatment was based on a predetermined protocol stratified by risk status. RESULTS: Of the 35 patients (mean age, 32 years), 26 (74%) had high-risk and nine (26%) had low-risk disease. Nineteen patients (54%) had undergone dilation and curettage and 11 (31%) had undergone hysterectomy before evaluation at BCCOE. Pathology reports were available in 48% of the molar pregnancy surgical cases. Systemic chemotherapy was initiated in 30 of the initial 35 patients: 13 (43%) received single-agent oral methotrexate, 15 (50%) received EMACO (etoposide, methotrexate, dactinomycin, cyclophosphamide, and vincristine), and two (7%) received alternate regimens. Of the 13 patients initiating methotrexate, three had their treatment intensified to EMACO. Four patients experienced treatment delays because of medication stockouts. At a median follow-up of 7.8 months, the survival probability for low-risk patients was 1.00; for high-risk patients, it was 0.63. CONCLUSION: This experience demonstrates the feasibility of GTN treatment in rural, resource-limited settings. GTN is a curable disease and can be treated following the BCCOE model of cancer care.

RESUMEN

OBJECTIVE: We sought to validate the clinicopathologic implications and prognostic significance of ATR (ataxia telangiectasia mutated and Rad3-related) mutation in patients with endometrioid endometrial cancer and defective DNA mismatch repair enrolled in a cooperative group molecular staging study of endometrial cancer. METHODS: After pathology review, only endometrioid tumors with high neoplastic cellularity (≥70%) and high quality DNA for molecular analyses were included. MSI (microsatellite instability) typing was performed and the target sequence in exon 10 of ATR was evaluated by direct sequencing in all MSI-high tumors. Associations between ATR mutations and clinicopathologic variables were assessed using contingency table tests. Differences in overall survival (OS) and disease-free survival (DFS) were evaluated by univariate analyses and multivariable Cox proportional hazard models. RESULTS: A total of 475 eligible cases were identified. Of 368 MSI+ cases, the sequence of interest could be successfully genotyped in 357 cases. ATR mutations were exclusively identified in 46 tumors with high level microsatellite instability (MSI+) (12.9%, p<0.001) and were associated with higher tumor grade (p=0.001). ATR mutations were not associated with OS (HR 1.16; 95% CI, 0.58-2.32; p=0.68) or DFS (HR 0.61; 95% CI, 0.25-1.50; p=0.28). CONCLUSION: Truncating mutations in exon 10 of ATR occur exclusively in tumors with evidence of defective DNA mismatch repair. We were not able to confirm the prognostic value of these mutations in patients with endometrioid endometrial cancer.

RESUMEN

INTRODUCTION: Optimal pain control after major surgery contributes to a patient's recovery and satisfaction. The use of liposomal bupivacaine in subcostal transversus abdominis plane (TAP) blocks for postoperative pain control after robot assisted abdominal surgery has yet to be studied. METHODS: We conducted a prospective randomized controlled observer-blinded study comparing bilateral subcostal TAP blocks with bupivacaine to bilateral subcostal TAP blocks with liposomal bupivacaine. These were performed prior to the patient undergoing robot assisted hysterectomy. The patients' pain scores, opioid use, side effects, and satisfaction were followed for 72h after injection. RESULTS: Total opioid use in the first 72h after injection was significantly decreased in the group that received liposomal bupivacaine compared to bupivacaine. Patients in the liposomal bupivacaine group had significantly lower maximal pain scores at all time periods studied as well as decreased incidence of nausea/vomiting. There was a trend toward decreased length of stay in the liposomal bupivacaine group. CONCLUSION: Subcostal TAP blocks with liposomal bupivacaine decreased the total opioid requirement for the first 72h after robot assisted hysterectomy when compared to subcostal TAP blocks with bupivacaine.

RESUMEN

UNLABELLED: Cervical cancer is more common in the Somali immigrant population than the general population in the United States (US). There are low rates of cervical cancer screening among Somali women. This study compares cervical cancer screening test completion rates for a home human papilloma virus (HPV) test and standard clinic Pap test. Sixty-three Somali immigrant women aged 30-70 years who had not undergone cervical cancer screening within the past 3 years were randomly assigned to a home HPV test group (intervention) or a clinic Pap test group (control). Test completion rates were measured at 3 months. Univariate and multivariate logistic regression models were used to explore factors associated with test completion (intention-to-treat analysis). Participants in the HPV test group were 14 times more likely to complete the test compared to those in the Pap test group (P = 0.0002). Women who reported having friends/family members to talk about cancer screening were approximately three times more likely to complete any screening test than those who did not (P = 0.127) and participants who reported residing in the US longer were more likely to complete a screening test (P = 0.011). Future research should explore the potential of using the home-based HPV test kits as an initial approach to cervical cancer screening. IMPACT: The use of a self-sampling HPV kit has the potential to increase cervical cancer screening in under-served communities in the US.

RESUMEN

This study examined barriers to and facilitators of cervical cancer screening among Somali immigrant women in Minnesota. We adopted the socioecological framework to illustrate screening barriers at multiple levels. We conducted 23 semi-structured key informant interviews and used a thematic exploratory approach to analyze the data. Barriers were classified into individual, community or health systems levels. Obstacles included lack of knowledge, religious beliefs, fatalism, fear, embarrassment, and lack of trust in the interpreters. Participants described a need for training of healthcare providers on issues surrounding Somali women's cultural practices and sexual health. Identifying individual, community, or health system barriers and addressing them concurrently may increase use of cancer screening services among Somali women. Future interventions need to address multilevel barriers with multilevel approaches to improve utilization of cervical cancer screening services in underserved immigrant populations in the United States.

RESUMEN

PURPOSE: Cancer survivors are at an increased risk for fractures, but lack of effective and economical biomarkers limits quantitative assessments of marrow fat (MF), bone mineral density (BMD) and their relation in response to cytotoxic cancer treatment. We report dual energy CT (DECT) imaging, commonly used for cancer diagnosis, treatment and surveillance, as a novel biomarker of MF and BMD. METHODS: We validated DECT in pre-clinical and phase I clinical trials and verified with water-fat MRI (WF-MRI), quantitative CT (QCT) and dual-energy X-ray absorptiometry (DXA). Basis material composition framework was validated using water and small-chain alcohols simulating different components of bone marrow. Histologic validation was achieved by measuring percent adipocyte in the cadaver vertebrae and compared with DECT and WF-MRI. For a phase I trial, sixteen patients with gynecologic malignancies (treated with oophorectomy, radiotherapy or chemotherapy) underwent DECT, QCT, WF-MRI and DXA before and 12months after treatment. BMD and MF percent and distribution were quantified in the lumbar vertebrae and the right femoral neck. RESULTS: Measured precision (3mg/cm(3)) was sufficient to distinguish test solutions. Adiposity in cadaver bone histology was highly correlated with MF measured using DECT and WF-MRI (r=0.80 and 0.77, respectively). In the clinical trial, DECT showed high overall correlation (r=0.77, 95% CI: 0.69, 0.83) with WF-MRI. MF increased significantly after treatment (p<0.002). Chemotherapy and radiation caused greater increases in MF than oophorectomy (p<0.032). L4 BMD decreased 14% by DECT, 20% by QCT, but only 5% by DXA (p<0.002 for all). At baseline, we observed a statistically significant inverse association between MF and BMD which was dramatically attenuated after treatment. CONCLUSION: Our study demonstrated that DECT, similar to WF-MRI, can accurately measure marrow adiposity. Both imaging modalities show rapid increase in MF following cancer treatment. Our results suggest that MF and BMD cannot be used interchangeably to monitor skeletal health following cancer therapy.

RESUMEN

BACKGROUND: Patient navigation programs are emerging that aim to address disparities in clinical trial participation among medically underserved populations, including racial/ethnic minorities. However, there is a lack of consensus on the role of patient navigators within the clinical trial process as well as outcome measures to evaluate program effectiveness. METHODS: A review of the literature was conducted of PubMed, Medline, CINHAL, and other sources to identify qualitative and quantitative studies on patient navigation in clinical trials. The search yielded 212 studies, of which only 12 were eligible for this review. RESULTS: The eligible studies reported on the development of programs for patient navigation in cancer clinical trials, including training and implementation among African Americans, American Indians, and Native Hawaiians. A low rate of clinical trial refusal (range, 4%-6%) was reported among patients enrolled in patient navigation programs. However, few studies reported on the efficacy of patient navigation in increasing clinical treatment trial enrollment. CONCLUSIONS: Outcome measures are proposed to assist in developing and evaluating the efficacy and/or effectiveness of patient navigation programs that aim to increase participation in cancer clinical trials. Future research is needed to evaluate the efficacy of patient navigators in addressing barriers to clinical trial participation and increasing enrollment among medically underserved cancer patients.

RESUMEN

Reliable tools for investigating ovarian cancer initiation and progression are urgently needed. While the use of ovarian cancer cell lines remains a valuable tool for understanding ovarian cancer, their use has many limitations. These include the lack of heterogeneity and the plethora of genetic alterations associated with extended in vitro passaging. Here we describe a method that allows for rapid establishment of primary ovarian cancer cells form solid clinical specimens collected at the time of surgery. The method consists of subjecting clinical specimens to enzymatic digestion for 30 min. The isolated cell suspension is allowed to grow and can be used for downstream application including drug screening. The advantage of primary ovarian cancer cell lines over established ovarian cancer cell lines is that they are representative of the original specific clinical specimens they are derived from and can be derived from different sites whether primary or metastatic ovarian cancer.

RESUMEN

Immigrant populations in the United States (US) have lower cancer screening rates compared to none immigrant populations. The purpose of this study was to assess the rates of cancer screening and examine factors associated with cancer screening behavior among African immigrant women in Minnesota. A cross sectional survey of a community based sample was conducted among African immigrants in the Twin Cities. Cancer screening outcome measures were mammography and Papanicolau smear test. The revised theoretical model of health care access and utilization and the behavioral model for vulnerable populations were utilized to assess factors associated with cancer screening. Only 61 and 52% of the age eligible women in the sample had ever been screened for breast and cervical cancer respectively. Among these women, duration of residence in the US and ethnicity were significant determinants associated with non-screening. Programs to enhance screening rates among this population must begin to address barriers identified by the community.

RESUMEN

BACKGROUND: Over 91,000 new cases of gynecological cancers are expected to be diagnosed in 2013 in the US alone. As cancer detection technology and treatment options improve, the number of working-age cancer survivors continues to grow. OBJECTIVE: To describe US gynecological cancer survivors' perceptions of the effects of cancer and treatment on their job tasks. PARTICIPANTS: 104 adult gynecological cancer survivors who were working at the time of their cancer diagnosis, treated at a University-based women's health clinic, diagnosed in the previous 24 months, and spoke English. METHODS: Women completed written surveys to describe their work experiences following diagnosis. Clinical characteristics were obtained through medical record review. Descriptive statistics and cross tabulations were performed to describe characteristics and associations. RESULTS: Fifteen percent of women had chemotherapy and radiation treatment; 48% had only chemotherapy, 9% only radiation therapy, and 28% had neither. Survivors described the frequency of performing seven job tasks, such as 'intense concentration', 'analyzing data', and 'lifting heavy loads.' Women who had undergone radiation treatment were more likely to indicate limitations for physical tasks; women undergoing chemotherapy were more likely to report limitations in more analytic tasks. Only 29% of women noted an employer-based policy facilitated their return-to-work process. CONCLUSIONS: Cancer and treatment have important effects on job performance and may vary by type of treatment. Employer-based policies focusing on improved communication and work accommodations may improve the return to work process.

RESUMEN

OBJECTIVE: To determine the disease characteristics and comorbidities predictive of vulvar cancer specific mortality and five year overall survival among older women, ages 65 and above. METHODS: A retrospective analysis was conducted of women diagnosed with vulvar cancer at a single regional cancer center from 1989 to 2003, with a follow up to 2009. Treatment records were extracted for: demographics and treatment information, Eastern Cooperative Oncology Group (ECOG) performance status and Charlson comorbidity index score. Probability of death from vulvar cancer was estimated using cumulative incidence, treating death by other known and unknown causes as competing risks. Predictors of overall survival were determined using multivariate Cox regression analyses. RESULTS: One hundred forty-six women were identified, with a median age at diagnosis of 79 years (range 65-95). Median follow up was 5.0 years (range 0.1-16.7 years). The cumulative incidence of vulvar cancer-specific mortality was 13% (95% CI: 0.08-0.19) at year one, 24% (95% CI: 0.17-0.31) at year three and 26% (95% CI: 0.19-0.33) at year five. Use of adjuvant therapy or surgical procedure performed did not differ by age at diagnosis (p=0.807 and 0.663) according to age group (65-74, 74-84 and 85+). Increasing age, Charlson comorbidity index score, lymph node involvement and type of surgery performed were associated with increased risk of death from any cause (all p<0.05). CONCLUSION: Among women aged ≥65, vulvar cancer specific mortality was most significant in the first three years after diagnosis. Conversely other causes of mortality which can be attributed to comorbid conditions steadily increased with time.
