RESUMEN

BACKGROUND: Standard therapy for advanced endometrial cancer after failure of platinum-based chemotherapy remains unclear. METHODS: In this phase 3 trial, we randomly assigned, in a 1:1 ratio, patients with advanced endometrial cancer who had previously received at least one platinum-based chemotherapy regimen to receive either lenvatinib (20 mg, administered orally once daily) plus pembrolizumab (200 mg, administered intravenously every 3 weeks) or chemotherapy of the treating physician's choice (doxorubicin at 60 mg per square meter of body-surface area, administered intravenously every 3 weeks, or paclitaxel at 80 mg per square meter, administered intravenously weekly [with a cycle of 3 weeks on and 1 week off]). The two primary end points were progression-free survival as assessed on blinded independent central review according to the Response Evaluation Criteria in Solid Tumors, version 1.1, and overall survival. The end points were evaluated in patients with mismatch repair-proficient (pMMR) disease and in all patients. Safety was also assessed. RESULTS: A total of 827 patients (697 with pMMR disease and 130 with mismatch repair-deficient disease) were randomly assigned to receive lenvatinib plus pembrolizumab (411 patients) or chemotherapy (416 patients). The median progression-free survival was longer with lenvatinib plus pembrolizumab than with chemotherapy (pMMR population: 6.6 vs. 3.8 months; hazard ratio for progression or death, 0.60; 95% confidence interval [CI], 0.50 to 0.72; P<0.001; overall: 7.2 vs. 3.8 months; hazard ratio, 0.56; 95% CI, 0.47 to 0.66; P<0.001). The median overall survival was longer with lenvatinib plus pembrolizumab than with chemotherapy (pMMR population: 17.4 vs. 12.0 months; hazard ratio for death, 0.68; 95% CI, 0.56 to 0.84; P<0.001; overall: 18.3 vs. 11.4 months; hazard ratio, 0.62; 95% CI, 0.51 to 0.75; P<0.001). Adverse events of grade 3 or higher occurred in 88.9% of the patients who received lenvatinib plus pembrolizumab and in 72.7% of those who received chemotherapy. CONCLUSIONS: Lenvatinib plus pembrolizumab led to significantly longer progression-free survival and overall survival than chemotherapy among patients with advanced endometrial cancer.

RESUMEN

The dorsal striatum is composed of the caudate nucleus and the putamen in human and non-human primates. These two regions receive different cortical projections and are functionally distinct. The caudate is involved in the control of goal-directed behaviors, while the putamen is implicated in habit learning and formation. Previous reports indicate that ethanol differentially influences neurotransmission in these two regions. Because neurotransmitters primarily signal through G protein-coupled receptors (GPCRs) to modulate neuronal activity, the present study aimed to determine whether ethanol had a region-dependent impact on the expression of proteins that are involved in the trafficking and function of GPCRs, including G protein subunits and their effectors, protein kinases, and elements of the cytoskeleton. Western blotting was performed to examine protein levels in the caudate and the putamen of male cynomolgus macaques that self-administered ethanol for 1 year under free access conditions, along with control animals that self-administered an isocaloric sweetened solution under identical operant conditions. Among the 18 proteins studied, we found that the levels of one protein (PKCß) were increased, and 13 proteins (Gαi1/3, Gαi2, Gαo, Gß1γ, PKCα, PKCε, CaMKII, GSK3ß, ß-actin, cofilin, α-tubulin, and tubulin polymerization promoting protein) were reduced in the caudate of alcohol-drinking macaques. However, ethanol did not alter the expression of any proteins examined in the putamen. These observations underscore the unique vulnerability of the caudate nucleus to changes in protein expression induced by chronic ethanol exposure. Whether these alterations are associated with ethanol-induced dysregulation of GPCR function and neurotransmission warrants future investigation.

RESUMEN

OBJECTIVE: To evaluate tiragolumab (anti-TIGIT) and atezolizumab (anti-PD-L1) as second- or third-line therapy for PD-L1-positive persistent/recurrent cervical cancer. METHODS: In the open-label, non-comparative, randomized phase II SKYSCRAPER-04 trial (NCT04300647), patients with PD-L1-positive (SP263 tumor area positivity ≥5%) recurrent/persistent cervical cancer after 1-2 chemotherapy lines (≥1 platinum-based) were randomized 3:1 to atezolizumab 1200 mg with/without tiragolumab 600 mg every 3 weeks until disease progression or unacceptable toxicity. Stratification factors were performance status, prior (chemo)radiotherapy, and disease status. The primary endpoint was independent review committee-assessed confirmed objective response rate per RECIST v1.1 in patients receiving tiragolumab plus atezolizumab. An objective response rate ≥21% (one-sample z-test p≤0.0245) was required for statistical significance versus a historical reference. RESULTS: Protocol-defined independent review committee-assessed objective response rates were 19.0% (95% CI 12.6 to 27.0) in 126 patients receiving tiragolumab plus atezolizumab (p=0.0787 vs historical reference) and 15.6% (95% CI 6.5 to 29.5) in 45 atezolizumab-treated patients. Response rates were higher in PD-L1high (tumor area positivity ≥10%) than PD-L1low (tumor area positivity 5%-9%) subgroups with both regimens. At 8.5 months' median follow-up, independent review committee-assessed progression-free survival was 2.8 months (95% CI 1.7 to 4.1) with tiragolumab plus atezolizumab and 1.9 months (95% CI 1.5 to 3.0) with atezolizumab. In post hoc analyses (10.4 months' median follow-up), median overall survival was 11.1 months (95% CI 9.6 to 14.5) with the combination and 10.6 months (95% CI 6.9 to 13.8) with atezolizumab (crossover permitted). In the combination group, 3% of patients had adverse events requiring treatment discontinuation and 8% had grade ≥3 adverse events of special interest; corresponding values in the single-agent arm were 4% and 11%. There were no treatment-related deaths or new safety findings. CONCLUSION: The objective response rate with the tiragolumab-plus-atezolizumab combination was numerically higher than the historical reference but did not reach statistical significance.

RESUMEN

BACKGROUND: To evaluate outcomes of laparoscopic retroperitoneal para-aortic lymphadenectomy for stage 1b3-3b cervical cancer. METHODS: Pathology databases searched for all para-aortic lymphadenectomy cases 2005-2016. Descriptive statistics were used to analyse baseline characteristics, cox models for treatment affect after accounting for variables, and Kaplan Meier curves for survival (STATA v15). RESULTS: 191 patients had 1b3-3b cervical cancer of which 110 patients had Para-aortic lymphadenectomy. 8 (7.3%) patients stage 1b3, 82 (74.6%) stage 2b, and 20 (18.1%) stage 3b cervical cancer. Mean lymph node count 11.7 (SD7.6). The intra-operative and post-operative 30 day complication rates were 8.8% (CI: 4.3%, 15.7%) and 5.3% (CI: 1.9%, 11.2%) respectively.Para-aortic nodes were apparently positive on CT/MRI in 5/110 (5%) cases. Cancer was found in 10 (8.9%, CI: 4.3%, 15.7%) cases on histology, all received extended field radiotherapy. Only 2 were identified on pre-operative CT/MRI imaging. 3 of 10 suspected node-positive cases on CT/MRI had negative histology. Para-aortic lymphadenectomy led to alteration in staging and radiotherapy management in 8 (8%, CI: 3.7%, 14.6%) patients. Mean overall survival 42.81 months (SD = 31.79 months). Survival was significantly higher for women undergoing PAN (50.57 (SD 30.7) months) compared to those who didn't (31.27 (SD 32.5) months). CONCLUSION: Laparoscopic retroperitoneal para-aortic lymphadenectomy is an acceptable procedure which can guide treatment in women with locally advanced cervical cancer.


We evaluated outcomes for patients with stage 1b3-3b cervical cancer that had lymph nodes removed prior to planning their chemoradiotherapy. There were 3 groups ­ patients that had their lymph nodes removed, those that did not and those that had their procedure abandoned so didn't have their lymph nodes removed. We looked at the lymph nodes down the microscope to see if they contained cancer and compared this to their pre-operative imaging. 8 patients had a change to their staging and treatment because they were found to have cancer in the lymph nodes. We found that the keyhole procedure to remove lymph nodes is an acceptable procedure which can guide treatment in women with locally advanced cervical cancer.

RESUMEN

Endometrial carcinosarcoma is a rare and aggressive high-grade endometrial carcinoma with secondary sarcomatous trans-differentiation (conversion theory). The clinical presentation and diagnostic work-up roughly align with those of the more common endometrioid counterpart, although endometrial carcinosarcoma is more frequently diagnosed at an advanced stage. Endometrial carcinosarcoma is not a single entity but encompasses different histological subtypes, depending on the type of carcinomatous and sarcomatous elements. The majority of endometrial carcinosarcomas are characterized by p53 abnormalities. The proportion of POLE and microsatellite instablity-high (MSI-H) is directly related to the epithelial component, being approximately 25% and 3% in endometrioid and non-endometrioid components.The management of non-metastatic disease is based on a multimodal approach with optimal surgery followed by (concomitant or sequential) chemotherapy and radiotherapy, even for early stages. Palliative chemotherapy is recommended in the metastatic or recurrent setting, with carboplatin/paclitaxel doublet being the first-line regimen. Although the introduction of immunotherapy plus/minus a tyrosine kinase inhibitor shifted the paradigm of treatment of patients with recurrent endometrial cancer, patients with endometrial carcinosarcoma were excluded from most studies evaluating single-agent immunotherapy or the combination. However, the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) approved the use of pembrolizumab and lenvatinib in endometrial cancer (all histotypes) after progression on chemotherapy and single-agent immunotherapy in MSI-H cancers. In the era of precision medicine, emerging knowledge on molecular endometrial carcinosarcoma is opening new promising therapeutic options for more personalized treatment. The present review outlines state-of-the-art knowledge and future directions for patients with endometrial carcinosarcoma.

RESUMEN

AIM: The purpose of this study was to explore whether grit is a predictor of success in associate degree nursing (ADN) programs. BACKGROUND: A question that challenges admission decision-making in nursing programs is "Who will succeed?" This question is particularly relevant in ADN programs, which often have higher attrition rates than baccalaureate programs. METHOD: This longitudinal, mixed-methods study was conducted with 451 ADN students across nine programs, including interviews with seven unsuccessful students and nine successful students. RESULTS: Short Grit Scale scores were not found to be statistically significant as a predictor of academic success; however, themes that emerged from the interviews do align with the theory of grit. CONCLUSION: Further research is needed to explore whether recognizing the level of grit in students during admission processes would help identify students who are likely to succeed.

RESUMEN

Clear cell endometrial carcinoma represents an uncommon and poorly understood entity. Data from molecular/genomic profiling highlighted the importance of various signatures in assessing the prognosis of endometrial cancer according to four classes of risk (POLE mutated, MMRd, NSMP, and p53 abnormal). Unfortunately, data specific to clear cell histological subtype endometrial cancer are lacking. More recently, data has emerged to suggest that most of the patients (more than 80%) with clear cell endometrial carcinoma are characterized by p53 abnormality or NSMP type. This classification has important therapeutic implications. Although it is an uncommon entity, clear cell endometrial cancer patients with POLE mutation seem characterized by a good prognosis. Chemotherapy is effective in patients with NSMP (especially in stage III and IV) and patients with p53 abnormal disease (all stages). While, preliminary data suggested that patients with MMRd are less likely to benefit from chemotherapy. The latter group appears to benefit much more from immune checkpoint inhibitors: recent data from clinical trials on pembrolizumab plus lenvatinib and nivolumab plus cabozantinib supported that immunotherapy plus tyrosine kinase inhibitors (TKI) would be the most appropriate treatment for recurrent non-endometrioid endometrial cancer (including clear cell carcinoma) after the failure of platinum-based chemotherapy. Moreover, ongoing clinical trials testing the anti-tumor activity of innovative products will clarify the better strategies for advanced/recurrent clear cell endometrial carcinoma. Further prospective evidence is urgently needed to better characterize clear cell endometrial carcinoma.

RESUMEN

Authors describe a quality improvement approach to develop and pilot test educational materials with an aim to educate MinuteClinic providers in the provision of age-friendly care using the 4Ms Framework: What Matters, Medication, Mentation, Mobility. The team used surveys, focus groups and site visits to develop educational prototypes with Plan-Do-Study-Act iterative cycles to improve the education. Educational materials introduced providers to 4Ms assessment and evidence-based act on strategies for older adults in the convenient care setting. The education activities included an interactive orientation module comparing standard care to 4Ms care, 10 video vignettes with experts addressing gerontological topics, and 12 grand rounds presented monthly on topics applying the 4Ms with older adults. The information gained from the staff aided in the development and the iterative improvement of the materials. This article highlights the benefits of using a quality improvement approach in development of clinician education in provision of age-friendly care.

RESUMEN

OBJECTIVE: Hospital based follow-up has been the standard of care for endometrial cancer. Patient initiated follow-up is a useful adjunct for lower risk cancers. The purpose of this study was to evaluate outcomes of endometrial cancer patients after stratification into risk groupings, with particular attention to salvageable relapses. METHODS: All patients treated surgically for International Federation of Gynecology and Obstetrics (FIGO) stage I-IVA endometrial cancer of all histological subtypes, from January 2009 until March 2019, were analyzed. Patient and tumor characteristics, treatment details, relapse, death, and last follow-up dates were collected. Site of relapse, presence of symptoms, and whether relapses were salvageable were also identified. The European Society of Medical Oncology-European Society of Gynecological Oncology 2020 risk stratification was assigned, and relapse free and overall survival were estimated. RESULTS: 900 patients met the eligibility criteria. Median age was 66 years (range 28-96) and follow-up duration was 35 months (interquartile range 19-57). In total, 16% (n=144) of patients relapsed, 1.3% (n=12) from the low risk group, 3.9% (n=35) from the intermediate risk group, 2.2% (n=20) from the high-intermediate risk group, and 8.7% (n=77) from the high risk group. Salvageable relapses were less frequent at 2% (n=18), of which 33% (n=6) were from the low risk group, 22% (n=4) from the intermediate risk group, 11% (n=2) from the high-intermediate risk group, and 33% (n=6) from the high risk group. There were only three asymptomatic relapses in the low risk patients, accounting for 0.33% of the entire cohort. CONCLUSIONS: Relapses were infrequent and most presented with symptoms; prognosis after relapse remains favorable. Overall salvageable relapses were infrequent and cannot justify intensive hospital based follow-up. Use of patient initiated follow-up is therefore appropriate, as per the British Gynaecological Cancer Society's guidelines, for all risk groupings.

RESUMEN

Cervical cancer is a global health problem which disproportionally affects women in low- and middle- income countries. The World Health Organization recently launched its global strategy to eliminate this disease in the next two decades. For those women diagnosed today with cervical cancer better strategies are needed to improve outcome and reduce treatment-related morbidity. Clinical trials are critical to shaping future treatment, and much has been achieved already. However, such opportunities are limited in low resource settings, and the Cervical Cancer Research Network is dedicated to expanding access to new technologies in surgery, radiation, and medical oncology. In this article we review the status of the trials portfolio and outline future objectives, including the launch of a number of research grants for aspiring or established researchers in low- and middle-income settings.

RESUMEN

Cervical cancer is the third most common cancer among women worldwide, with a disproportionately high burden of disease in less-developed regions of the world. The Cervix Cancer Research Network was founded by the Gynecologic Cancer InterGroup with a mission to improve outcomes in cervical cancer by enhancing international access to clinical trials, specifically in under-represented, underdeveloped areas. The Cervix Cancer Research Network held its third international educational symposium in Bucharest in 2018 and is the subject of this report. The purpose of this symposium was to advance the international understanding of cervical cancer treatment patterns, to foster recruitment to Cervix Cancer Research Network clinical trials, and identify key Cervix Cancer Research Network clinical trial concepts to improve cervical cancer care worldwide.

RESUMEN

BACKGROUND: Quality issues in the delivery of healthcare services to older adults and changes in societal demographics call for a social movement to improve the care of older adults in a variety of healthcare settings, including ambulatory care and convenient care clinics. AIMS: To describe the pre-implementation phase to integrate the Age-Friendly Health Systems (AFHS) 4Ms (i.e., What Matters, Medication, Mentation, and Mobility) Framework in 1,100 MinuteClinics (the retail medical clinic of CVS Health) using the Consolidated Framework for Implementation Research (CFIR) and RE-AIM (an evaluation implementation framework). METHODS: The CFIR and RE-AIM models guided data collection. Data were collected from all stakeholders (patients, healthcare providers, managers, educators, informatics staff, communications staff, and implementation consultants) via observations, surveys, interviews, focus groups, organizational readiness assessment, stakeholder assessment, and workflow mapping during a 15-month period to identify potential barriers, facilitators, and other opportunities for implementation. RESULTS: The CFIR and RE-AIM implementation frameworks provided a comprehensive approach to guide the pre-implementation phase of the AFHS 4Ms Framework at the MinuteClinic. The baseline assessments guided by the CFIR revealed important insights in the choice of implementation strategies that were developed and tested in the pre-implementation phase, and the RE-AIM guided meaningful components to the development of the logic model. LINKING ACTION TO EVIDENCE: As more healthcare systems integrate the AFHS 4Ms Framework, the approach reported in this quality improvement project can be used in other settings to facilitate a comprehensive implementation.

RESUMEN

OBJECTIVE: Adding bevacizumab to cisplatin-paclitaxel for advanced cervical cancer significantly improves overall and progression-free survival. We evaluated bevacizumab with a widely used carboplatin-paclitaxel backbone. METHODS: Patients with metastatic/recurrent/persistent cervical cancer not amenable to curative surgery and/or radiotherapy received 3-weekly bevacizumab 15 mg/kg, paclitaxel 175 mg/m2, and carboplatin AUC 5 until progression or unacceptable toxicity. Maintenance bevacizumab was allowed. Patients with ongoing bladder/rectal involvement, prior cobalt radiotherapy, a history of fistula/gastrointestinal perforation, or recent bowel resection/chemoradiation were excluded. The primary objective was to determine incidences of gastrointestinal perforation/fistula, gastrointestinal-vaginal fistula, and genitourinary fistula. RESULTS: Among 150 treated patients, disease at study entry was persistent in 21%, recurrent in 56%, and newly diagnosed metastatic in 23%. After 27.8 months' median follow-up, median bevacizumab duration was 6.7 months; 57% received maintenance bevacizumab. Seventeen patients (11.3%; 95% CI: 6.7-17.5%) experienced ≥1 perforation/fistula event: gastrointestinal perforation/fistula in 4.7% (1.9-9.4%), gastrointestinal-vaginal fistula in 4.0% (1.5-8.5%), and genitourinary fistula in 4.7% (1.9-9.4%). Of these, 16 were previously irradiated, several with ongoing radiation effects. The most common grade 3/4 adverse events were neutropenia (25%), anemia (19%), and hypertension (14%). Five patients (3%) had fatal adverse events. Objective response rate was 61% (95% CI: 52-69%), median progression-free survival was 10.9 (10.1-13.7) months, and median overall survival was 25.0 (20.9-30.4) months. CONCLUSIONS: Bevacizumab can be combined with carboplatin-paclitaxel in the CECILIA study population. The fistula/gastrointestinal perforation incidence is in line with GOG-0240; efficacy results are encouraging. TRIAL REGISTRATION NUMBER: NCT02467907 (ClinicalTrials.gov).

RESUMEN

OBJECTIVE: Pathogenic BRCA variants account for 5.8-24.8% of ovarian cancers. The identification of such a variant can have a significant impact on the affected individual and their relatives, determining eligibility for targeted therapies, predicting treatment response, and granting access to disease prevention strategies. Cancer services are responding to the increased demand for genetic testing with the introduction of mainstreamed genetic testing via oncology clinics. This study aimed to evaluate patient experience of the mainstreamed genetic testing pathway at a tertiary referral center in London, UK. METHODS: Study participants were patients diagnosed with high-grade non-mucinous ovarian cancer, tested via a mainstreamed genetic testing pathway at the tertiary referral center between February 2015 and June 2017. Eligible participants were invited to complete the retrospective study questionnaire. Five quantitative measures with additional free-text items were used to evaluate the patient experience of mainstreamed genetic testing. RESULTS: The tertiary referral center tested 170 ovarian cancer patients. Twenty-three pathogenic BRCA mutations were identified (23/170, 13.5%). One-hundred and six patients (106/170, 62.4%) met the study inclusion criteria. Twenty-nine of those invited to participate (29/106, 27.4%) returned the retrospective study questionnaire. Pathogenic BRCA1/2 variants were identified within four respondents (4/29, 13.8%). Motivations for genetic testing related to improved medical management, and the ability to provide relatives with genetic information. Participants did not appear to be adversely affected by result disclosure post-mainstreamed genetic testing. Two individuals with a pathogenic variant reported that the support provided by the tertiary referral center post-result disclosure could have been improved. CONCLUSION: Results of the current study support further psychosocial research into the expansion of the mainstreamed genetic testing pathway. The results, although promising, have also highlighted the importance of genetic awareness within the multi-disciplinary team and the provision of timely psychological support from genetic specialists.

RESUMEN

BACKGROUND: Ovarian cancer is the fifth most common cause of cancer death for women in the UK. Up to 18% of cases can be attributed to germline mutations in BRCA1 and BRCA2genes. Identifying patients who carry a BRCA mutation provides important information about potential response to treatment and eligibility for therapies such as poly ADP ribose polymerase (PARP) inhibitors. Implementation of systematic genetic testing of patients with ovarian cancer via oncology clinics (mainstreamed genetic testing, MGT) is increasing. METHODS AND RESULTS: This service evaluation reports on the first year of MGT at a tertiary oncology centre in London, UK. In total, 122 patients with high-grade non-mucinous ovarian cancer underwent BRCA germline testing via MGT. Eighteen patients (14.8%) were found to carry a deleterious BRCA1/BRCA2 mutation. Four BRCA carriers did not meet previous criteria for genetic testing and would have been missed. Six BRCA carriers accessed PARP inhibitors post-MGT. Only 22% of patients with a variant of unknown significance (VUS) were referred to clinical genetics services. CONCLUSIONS: MGT appears to be a feasible way of providing BRCA testing to patients with ovarian cancer. Greater clarity of how oncologists use VUS results is needed, as well as further research on psychosocial implications of MGT for patients with ovarian cancer, which may include somatic testing in the future.

RESUMEN

BACKGROUND: Radical hysterectomy and complete pelvic lymphadenectomies are the most commonly performed procedures for women with early-stage cervical cancer. Sentinel lymph node (SLN) mapping could be an alternative to routine pelvic lymphadenectomy, aiming to diagnose accurately nodal extension and decrease lymphatic morbidity. PRIMARY OBJECTIVE: To compare 3-year disease-free survival and health-related quality of life after SLN biopsy or SLN biopsy + pelvic lymphadenectomy in early cervical cancer. STUDY HYPOTHESIS: We hypothesize that disease-free survival is non-inferior and health-related quality of life superior after SLN biopsy compared with SLN biopsy + pelvic lymphadenectomy. TRIAL DESIGN: International, randomized, multicenter, single-blind trial. The study will be run by teams trained to carry out SLN biopsy, belonging to clinical research cooperative groups or recognized as experts in this field. Patients with an optimal mapping (Memorial Sloan Kettering Cancer Center [MSKCC] criteria) and a negative frozen section will be randomized 1:1 to SLN biopsy only or SLN biopsy + pelvic lymphadenectomy. INCLUSION, EXCLUSION CRITERIA: Patients with early stages (Ia1 with lymphovascular invasion to IIa1) of disease. Histological types are limited to squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma. PRIMARY ENDPOINT: Main endpoint will be co-primary endpoint, associating 3-year disease-free survival and quality of life (QLQ-C30 and QLQ-CX24). SAMPLE SIZE: 950 patients need to be randomized.Estimated dates for completing accrual and presenting results: study started on Q2 2018, last accrual is scheduled for Q2 2021, and last follow-up in Q2 2026. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03386734.

RESUMEN

BACKGROUND: Despite significant advances in the screening, detection, and treatment of preinvasive cervical lesions, invasive cervical cancer is the fifth most common cancer in European women. There are large disparities in Europe and worldwide in the incidence, management, and mortality of cervical cancer. OBJECTIVE: The European Society of Gynaecological Oncology (ESGO), the European Society for Radiotherapy and Oncology (ESTRO), and the European Society of Pathology (ESP) jointly develop clinically relevant and evidence-based guidelines in order to improve the quality of care for women with cervical cancer across Europe and worldwide. METHODS: The ESGO/ESTRO/ESP nominated an international multidisciplinary development group consisting of practicing clinicians and researchers who have demonstrated leadership and expertise in the care and research of cervical cancer (23 experts across Europe). To ensure that the guidelines are evidence based, the current literature identified from a systematic search was reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the development group. The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 159 international reviewers, selected through ESGO/ESTRO/ESP and including patient representatives. RESULTS: The guidelines cover comprehensively staging, management, and follow-up for patients with cervical cancer. Management includes fertility sparing treatment; stage T1a, T1b1/T2a1, clinically occult cervical cancer diagnosed after simple hysterectomy; early and locally advanced cervical cancer; primary distant metastatic disease; cervical cancer in pregnancy; and recurrent disease. Principles of radiotherapy and pathological evaluation are defined.

RESUMEN

OBJECTIVE: To assess the outcome of patients with advanced ovarian cancer (OC) who were treated without surgery, having received upfront chemotherapy and no interval debulking surgery (IDS). METHODS: Retrospective analysis of medical and chemotherapy records of consecutive patients with OC between 2005 and 2013 at UCL Hospitals London, UK who received neoadjuvant chemotherapy (NACT) was then found to be unsuitable for IDS following review by the multidisciplinary team. RESULTS: Eighty-three patients (18%) out of 467 receiving NACT did not undergo IDS. Median age was 70years (range 33-88); out of these 83 patients, 43 (51.8%) presented with stage IV disease. Forty-three of these 83 patients received carboplatin and paclitaxel (CP) (51.8%) and 37 received carboplatin alone (C) (44.6%); 3 patients (3.6%) received other platinum-based combinations. Reasons for not proceeding to surgery were: poor response to chemotherapy after 3-4 cycles of NACT (61/83, 73.5%); comorbidities (12/83, 14.5%); patient decision (4/83, 4.8%). Six patients (7.2%) received <3 cycles of NACT due to a worsening clinical condition. The median overall survival (OS) for patients not undergoing IDS was 18months (95% CI 10-20months). Forty-four of 83 patients (53%) received >2 lines of chemotherapy. In a univariate analysis CP, age <70years, and absence of comorbidities were factors influencing OS. In a multivariate analysis only having received CP remained independently associated with OS (HR 0.49, 95% CI 0.29-0.84). CONCLUSIONS: Chemotherapy alone can provide reasonable disease control in patients unsuitable for IDS and CP should be used if possible.

RESUMEN

OBJECTIVE: Despite advances in cervical cancer prevention and diagnosis, outcomes for patients given a diagnosis of advanced and recurrent disease are poor. In the GOG240 trial, the addition of bevacizumab to paclitaxel-topotecan or paclitaxel-cisplatin has been shown to prolong survival compared with paclitaxel-topotecan or paclitaxel-cisplatin in patients with persistent, recurrent, or metastatic disease. However, standards of care vary between regions and countries. The purpose of this systematic review and network meta-analysis was to enable a comparison between bevacizumab + chemotherapy with multiple monotherapy or combination chemotherapy regimens in the treatment for women with advanced, recurrent, or persistent cervical cancer. METHODS/MATERIALS: A systematic literature review was conducted to identify randomized or nonrandomized controlled trials of patients with recurrent, persistent, or metastatic cervical cancer published in English from 1999 to 2015. A feasibility study was performed to assess the heterogeneity of the trials, and a network meta-analysis was conducted. Fixed- and random-effects models were fitted to calculate the hazard ratio for overall survival (OS) for all pairwise comparisons and ranking of all interventions. RESULTS: Twenty-three studies (19 trials) met inclusion criteria and were included in the review. Sample sizes ranged from 69 to 452, and median patient age ranged from 45 to 53 years. There was a trend toward prolonged OS with cisplatin-paclitaxel-bevacizumab and topotecan-paclitaxel-bevacizumab compared with all non-bevacizumab-containing therapies. Cisplatin-paclitaxel-bevacizumab had the highest probability of being the most efficacious compared with all regimens (68.1%), and cisplatin monotherapy had the lowest (0%). CONCLUSIONS: The results of this network meta-analysis show that bevacizumab in combination with paclitaxel-topotecan or paclitaxel-cisplatin is likely to prolong OS over other non-bevacizumab-containing chemotherapies (eg, paclitaxel-carboplatin), which were not included in the GOG240 trial. In patients with advanced, persistent, and recurrent cervical cancer, cisplatin-paclitaxel-bevacizumab and topotecan-paclitaxel-bevacizumab showed the highest efficacy in all regimens investigated in this analysis.

RESUMEN

BACKGROUND: This is a feasibility study to determine whether circulating tumour cells (CTCs) are detectable and suitable for molecular profiling in advanced endometrial cancer (aEC). METHOD: Between October 2012 and February 2014, 30 patients with aEC had baseline and up to 3 follow-up samples. CTCs and stathmin expression were evaluated using the CellSearch platform. Epithelial cell adhesion molecule (EpCAM) and stathmin immunohistochemistry were performed on FFPE tumour tissue. RESULTS: Eighteen from 30 (60%) patients had detectable CTCs during study [1 CTC (n = 7), 2 (n = 4), 3 (n = 1), 4 (n = 2), 7 (n = 1), 8 (n = 1), 22 (n = 1), 172 (n = 1) in 7.5 ml blood]. Ten from 18 patients had between 50 and 100% of detectable CTCs that were stathmin positive. More CTC-positive than CTC-negative patients had non-endometrioid versus endometrioid histology, tumour size ≥5 versus <5 cm, higher-stage disease and worse survival [hazard ratio 3.3, p > 0.05, 95% confidence interval 0.7-16.2]. Twenty-one tumour blocks were tested for EpCAM and stathmin immunohistochemistry (IHC). Stathmin tumour immunostaining scores (TIS) on IHC were higher in CTC-positive patients. CONCLUSION: CTC enumeration and molecular profiling with stathmin on the CellSearch platform is feasible in aEC. Stathmin TIS on IHC, a known prognostic marker in EC, was associated with CTC positivity.
