RESUMO

PURPOSE: To identify whether race/ethnicity plays a role in knowledge of clinical trials among patients with a gynecologic malignancy. PATIENTS AND METHODS: A cross-sectional survey was conducted at a tertiary medical center. Participants were adults (≥18 years old), with gynecologic malignancy, and literate in English, Spanish or Chinese. Participants completed a 9-item clinical trial knowledge assessment. Demographic characteristics were summarized using descriptive statistics. A multivariable model was employed to evaluate the relationship between race/ethnicity and clinical trial knowledge. RESULTS: 245 patients were approached, 25 (10.2%) declined. Among participants, 108 (50.2%) were white, and 107 (49.8%) were people of color. Significant differences were noted for age, education, birthplace, and income; no difference was observed for cancer type or stage. The median number of correct answers for the knowledge assessment was seven. 67 (62%) white vs 26 (24.3%) people of color had an above average clinical trial knowledge score (p < 0.001). Multivariable analysis showed white participants were 2.7 times more likely to have an above average clinical trial knowledge score. White participants overall utilized more resources. Elder adults (≥65 years old) had higher knowledge of clinical trials compared to non-elder adults (<65 years old); however, these findings were not significant. CONCLUSION: This study observed significant differences in clinical trial knowledge between white and people of color diagnosed with a gynecologic malignancy. White patients utilize more informational resources compared to people of color. Further studies need to develop resources and outreach mechanisms that will increase access and diversity in clinical trial participation.

RESUMO

In February of 2024, the Society of Gynecologic Oncology (SGO) hosted a journal club focused on new treatment options for the management of advanced and metastatic endometrial cancer. This clinical commentary is intended to provide a summary report of that presentation. The session described the importance of molecular characterization shown in the work of The Cancer Genome Atlas (TCGA). The updated 2023 FIGO staging of endometrial cancer was reviewed. The panel then described the role of upfront immunotherapy for the treatment of advanced or recurrent endometrial cancer as demonstrated in four recent trials (RUBY, NRG-GY018, AtTEnd, and DUO-E studies). The DUO-E study uniquely examined the combination immunotherapy with a PARP inhibitor. The trials had unique differences in inclusion criteria, primary outcomes, and length of maintenance therapy, but all boasted similarly promising results particularly in mismatch repair deficient (dMMR) endometrial cancer. This era of rapid innovation in advanced and recurrent endometrial cancer will hopefully enhance individualized treatment approaches and improved outcomes for patients with endometrial cancer.

RESUMO

PURPOSE: To explore safety and tolerability parameters for the niraparib individualized starting dose (ISD) in patients with newly diagnosed advanced ovarian cancer that responded to platinum-based chemotherapy who participated in the phase 3 PRIMA/ENGOT-OV26/GOG-3012 trial (NCT02655016). METHODS: The PRIMA protocol was amended so newly enrolled patients received an ISD based on baseline body weight/platelet count. In this ad hoc analysis, the timing, duration, and resolution of the first occurrence of common any-grade hematologic (thrombocytopenia, anemia, neutropenia) and nonhematologic (nausea, asthenia/fatigue, constipation, insomnia, hypertension) treatment-emergent adverse events (TEAEs) were evaluated by treatment arm in the ISD safety population (data cutoff, November 17, 2021; median follow-up, 3.5 years). RESULTS: Of 733 randomized patients, 255 were enrolled after the ISD protocol amendment and received ≥ 1 dose of study treatment (niraparib, 169; placebo, 86). In the niraparib arm, median times to first events were 22.0-35.0 days for hematologic TEAEs and 7.0-56.0 days for nonhematologic TEAEs. First events resolved in ≥ 89.8% of patients for hematologic TEAEs; for nonhematologic TEAEs, resolution rates ranged from 55.3% (insomnia) to 86.0% (nausea). Median durations of first hematologic TEAEs were ≤ 16.0 days, but for first nonhematologic TEAEs ranged from 18.0 days (nausea) to 134.0 days (insomnia). CONCLUSION: The niraparib ISD was generally well tolerated and TEAEs were manageable. Common hematologic and nonhematologic TEAEs occurred early and first events of hematologic TEAEs had a short duration (≈ 2 weeks) and a high resolution rate. These findings support close monitoring immediately following niraparib initiation and may help inform patient expectations for niraparib safety.

RESUMO

BACKGROUND: The identification of cancer driver genes from sequencing data has been crucial in deepening our understanding of tumor biology and expanding targeted therapy options. However, apart from the most commonly altered genes, the mechanisms underlying the contribution of other mutations to cancer acquisition remain understudied. Leveraging on our whole-exome sequencing of the largest Asian lung adenocarcinoma (LUAD) cohort (n = 302), we now functionally assess the mechanistic role of a novel driver, PARP4. METHODS: In vitro and in vivo tumorigenicity assays were used to study the functional effects of PARP4 loss and mutation in multiple lung cancer cell lines. Interactomics analysis by quantitative mass spectrometry was conducted to identify PARP4's interaction partners. Transcriptomic data from cell lines and patient tumors were used to investigate splicing alterations. RESULTS: PARP4 depletion or mutation (I1039T) promotes the tumorigenicity of KRAS- or EGFR-driven lung cancer cells. Disruption of the vault complex, with which PARP4 is commonly associated, did not alter tumorigenicity, indicating that PARP4's tumor suppressive activity is mediated independently. The splicing regulator hnRNPM is a potentially novel PARP4 interaction partner, the loss of which likewise promotes tumor formation. hnRNPM loss results in splicing perturbations, with a propensity for dysregulated intronic splicing that was similarly observed in PARP4 knockdown cells and in LUAD cohort patients with PARP4 copy number loss. CONCLUSIONS: PARP4 is a novel modulator of lung adenocarcinoma, where its tumor suppressive activity is mediated not through the vault complex-unlike conventionally thought, but in association with its novel interaction partner hnRNPM, thus suggesting a role for splicing dysregulation in LUAD tumorigenesis.

RESUMO

Introduction: Across specialties, surgeons over-prescribe opioids to patients after surgery. We aimed to develop and implement an evidence-based calculator to inform post-discharge opioid prescription size for gynecologic oncology patients after laparotomy. Methods: In 2021, open surgical gynecologic oncology patients were called 2-4 weeks after surgery to ask about their home opioid use. This data was used to develop a calculator for post-discharge opioid prescription size using two factors: 1) age of the patient, 2) oral morphine equivalents (OME) used by patients the day before hospital discharge. The calculator was implemented on the inpatient service from 8/21/22 and patients were contacted 2-4 weeks after surgery to again assess their opioid use at home. Results: Data from 95 surveys were used to develop the opioid prescription size calculator and are compared to 95 post-intervention surveys. There was no difference pre- to post-intervention in demographic data, surgical procedure, or immediate postoperative recovery. The median opioid prescription size decreased from 150 to 37.5 OME (p < 0.01) and self-reported use of opioids at home decreased from 22.5 to 7.5 OME (p = 0.05). The refill rate did not differ (12.6 % pre- and 11.6 % post-intervention, p = 0.82). The surplus of opioids our patients reported having at home decreased from 1264 doses of 5 mg oxycodone tabs in the pre-intervention cohort, to 490 doses in the post-intervention cohort, a 61 % reduction. Conclusions: An evidence-based approach for prescribing opioids to patients after laparotomy decreased the surplus of opioids we introduced into our patients' communities without impacting refill rates.

RESUMO

BACKGROUND: A well-known complication of laparoscopic management of gynaecologic masses and cancers is the need to perform an intraoperative conversion to laparotomy. The purpose of this study was to identify novel patient risk factors for conversion from minimally invasive to open surgeries for gynaecologic oncology operations. METHODS: This was a retrospective cohort study of 1356 patients ≥18 years of age who underwent surgeries for gynaecologic masses or malignancies between February 2015 and May 2020 at a single academic medical centre. Multivariable logistic regression was used to study the effects of older age, higher body mass index (BMI), higher American Society of Anaesthesiologist (ASA) physical status, and lower preoperative haemoglobin (Hb) on odds of converting from minimally invasive to open surgery. Receiver operating characteristic (ROC) curve analysis assessed the discriminatory ability of a risk prediction model for conversion. RESULTS: A total of 704 planned minimally invasive surgeries were included with an overall conversion rate of 6.1% (43/704). Preoperative Hb was lowest for conversion cases, compared to minimally invasive and open cases (11.6 ± 1.9 vs 12.8 ± 1.5 vs 11.8 ± 1.9 g/dL, p<.001). Patients with preoperative Hb <10 g/dL had an adjusted odds ratio (OR) of 3.94 (CI: 1.65-9.41, p=.002) for conversion while patients with BMI ≥30 kg/m2 had an adjusted OR of 2.86 (CI: 1.50-5.46, p=.001) for conversion. ROC curve analysis using predictive variables of age >50 years, BMI ≥30 kg/m2, ASA physical status >2, and preoperative haemoglobin <10 g/dL resulted in an area under the ROC curve of 0.71. Patients with 2 or more risk factors were at highest risk of requiring an intraoperative conversion (12.0%). CONCLUSIONS: Lower preoperative haemoglobin is a novel risk factor for conversion from minimally invasive to open gynaecologic oncology surgeries and stratifying patients based on conversion risk may be helpful for preoperative planning.


Minimally invasive surgery for management of gynaecologic masses (masses that affect the female reproductive organs) is often preferred over more invasive surgery, because it involves smaller surgical incisions and can have overall better recovery time. However, one unwanted complication of minimally invasive surgery is the need to unexpectedly convert the surgery to an open surgery, which entails a larger incision and is a higher risk procedure. In our study, we aimed to find patient characteristics that are associated with higher risk of converting a minimally invasive surgery to an open surgery. Our study identified that lower levels of preoperative haemoglobin, the protein that carries oxygen within red blood cells, is correlated with higher risk for conversion. This new risk factor was used with other known risk factors, including having higher age, higher body mass index, and higher baseline medical complexity to create a model to help surgical teams identify high risk patients for conversion. This model may be useful for surgical planning before and during the operation to improve patient outcomes.

RESUMO

BACKGROUND: Racial and ethnic disparities in pain management are well documented. Differences in pain assessment and management by language have not been studied in the postoperative setting in gynecologic surgery. OBJECTIVE: This study aimed to investigate the association between language and immediate postoperative pain management by comparing pain assessments and perioperative opioid use in non-English speakers and English speakers. STUDY DESIGN: This was a retrospective cohort study comparing perioperative outcomes between non-English-speaking patients and English-speaking patients who had undergone a gynecologic oncology open surgery between July 2012 and December 2020. The primary language was extracted from the electronic medical record. Opioid use is expressed in oral morphine equivalents. Proportions are compared using chi-square tests, and mean values are compared using 2-sample t tests. Although interpreter services are widely available in our institution, the use of interpreters for any given inpatient-provider interaction is not documented. RESULTS: Between 2012 and 2020, 1203 gynecologic oncology patients underwent open surgery, of whom 181 (15.1%) were non-English speakers and 1018 (84.9%) were English speakers. There was no difference between the 2 cohorts concerning body mass index, surgical risk score, or preoperative opioid use. Compared with the English-speaking group, the non-English-speaking group was younger (57 vs 54 years old, respectively; P<.01) and had lower rates of depression (26% vs 14%, respectively; P<.01) and chronic pain (13% vs 6%, respectively; P<.01). Although non-English-speaking patients had higher rates of hysterectomy than English-speaking patients (80% vs 72%, respectively; P=.03), there was no difference in the rates of bowel resections, adnexal surgeries, lengths of surgery, intraoperative oral morphine equivalents administered, blood loss, use of opioid-sparing modalities, lengths of hospital stay, or intensive care unit admissions. In the postoperative period, compared with English-speaking patients, non-English-speaking patients received fewer oral morphine equivalents per day (31.7 vs 43.9 oral morphine equivalents, respectively; P<.01) and had their pain assessed less frequently (7.7 vs 8.8 checks per day, respectively; P<.01) postoperatively. English-speaking patients received a median of 19.5 more units of oral morphine equivalents daily in the hospital and 205.1 more units of oral morphine equivalents at the time of discharge (P=.02 and P=.04, respectively) than non-English-speaking patients. When controlling for differences between groups and several factors that may influence oral morphine equivalent use, English-speaking patients received a median of 15.9 more units of oral morphine equivalents daily in the hospital cohort and similar oral morphine equivalents at the time of discharge compared with non-English-speaking patients. CONCLUSION: Patients who do not speak English may be at risk of undertreated pain in the immediate postoperative setting. Language barrier, frequency of pain assessments, and provider bias may perpetuate disparity in pain management. Based on this study's findings, we advocate for the use of regular verbal pain assessments with language-concordant staff or medical interpreters for all postoperative patients.

RESUMO

Ovarian cancer is the most deadly female gynaecological malignancy in developed countries and new treatments are urgently needed. The luteinising hormone releasing hormone (LHRH) peptide drug conjugate Zoptarelin doxorubicin is one such potential new drug modality that entered clinical trials for treating LHRH receptor-positive gynaecological cancers. However, development stopped after disappointing Phase 3 results in 2017. We believe the lack of efficacy was due to linker instability and payload potency. In this work, we replaced its linker-toxin with vedotin (MC-VC-PABC-MMAE), yielding the novel peptide drug conjugate D-Cys6-LHRH vedotin. A GI50 and cell specificity comparison against cancerous and non-cancerous ovarian cell lines showed significantly superior bioactivity and selectivity over Zoptarelin doxorubicin (GI50 4 vs. 453 nM) and other chemotherapeutic drugs used for treating ovarian cancers. Our results suggest D-Cys6-LHRH vedotin can potentially be used as a treatment for ovarian cancer.

RESUMO

Objective: To assess the impact of an evidence-informed protocol for management of placenta accreta spectrum (PAS). Methods: This was a retrospective cohort study of patients who underwent cesarean hysterectomy (c-hyst) for suspected PAS from 2012 to 2022 at a single tertiary care center. Perioperative outcomes were compared pre- and post-implementation of a standardized Multidisciplinary Approach to the Placenta Service (MAPS) protocol, which incorporates evidence-informed perioperative interventions including preoperative imaging and group case review. Intraoperatively, the MAPS protocol includes placement of ureteral stents, possible placental mapping with ultrasound, and uterine artery embolization by interventional radiology. Patients suspected to have PAS on prenatal imaging who underwent c-hyst were included in the analysis. Primary outcomes were intraoperative complications and postoperative complications. Secondary outcomes were blood loss, need for ICU, and length of stay. Proportions were compared using Fisher's exact test, and continuous variables were compared used t-tests and Mood's Median test. Results: There were no differences in baseline demographics between the pre- (n = 38) and post-MAPS (n = 34) groups. The pre-MAPS group had more placenta previa (95% pre- vs. 74% post-MAPS, p = 0.013) and prior cesarean sections (2 prior pre- vs. 1 prior post-MAPS, p = 0.012). The post-MAPS group had more severe pathology (PAS Grade 3 8% pre- vs. 47% post-MAPS, p = 0.001). There were fewer intraoperative complications (39% pre- vs.3% post-MAPS, p < 0.001), postoperative complications (32% pre- vs.12% post-MAPS, p = 0.043), hemorrhages >1l (95% pre- vs.65% post-MAPS, p = 0.001), ICU admissions (59% pre- vs.35% post-MAPS, p = 0.04) and shorter hospital stays (10 days pre- vs.7 days post-MAPS, p = 0.02) in the post-MAPS compared to pre-MAPS patients. Neonatal length of stay was 8 days longer in the post-MAPS group (9 days pre- vs. 17 days post-MAPS, p = 0.03). Subgroup analyses demonstrated that ureteral stent placement and uterine artery embolization (UAE) may be important steps to reduce complications and ICU admissions. When comparing just those who underwent UAE, patients in the post-MAPS group experienced fewer hemorrhages greater five liters (EBL >5l 43% pre- vs.4% post-MAPS, p = 0.007). Conclusion: An evidence-informed approach to management of PAS was associated with decreased complication rate, EBL >1l, ICU admission and length of hospitalization, particularly for patients with severe pathology.

RESUMO

Prolonged exposure to environmentally relevant amounts of cadmium (Cd) in aquatic environments, even at small doses (0.1 and 1 µg/L), might endanger the health of underwater creatures. This research delved into the impacts of a four-month cadmium exposure on Mozambique tilapia (Oreochromis mossambicus), aiming to uncover the mechanisms behind it. Through close examination, we found that the 4-momth cadmium exposure led to harmful effects on the fish's gills, muscles, brain, and intestines. This exposure also triggered changes in gene expressions in the brain and liver, affected the respiratory system and weakened liver's ability to detoxify and defend against potential infections. Looking deeper into the fish's gut, we noticed alterations in energy-related genes and disruptions in immune pathways, making it more susceptible to illnesses. The exposure to cadmium also had an impact on the fish's gut and water-dwelling microorganisms, reducing diversity and encouraging harmful microbial communities. Interestingly, some gut microbes seemed to assist in breaking down and detoxifying cadmium, which could potentially protect the fish. Taken together, prolonged low-level cadmium exposure impaired gill, muscle, and brain function, suppressed immunity, disrupted intestines, and altered microbial balance, leading to hindered growth. These insights illuminate cadmium's impact on fish, addressing vital environmental concerns.

RESUMO

Background: Literature evaluating the management of abnormal uterine bleeding in premenopausal patients prior to endometrial malignancy diagnosis is lacking. Objective: To evaluate predictors and consequences of inadequate evaluation and management of abnormal uterine bleeding and time to endometrial sampling in premenopausal patients prior to endometrial malignancy diagnosis.Study Design.This was a retrospective cohort study of premenopausal individuals with endometrioid endometrial cancer or atypical hyperplasia at a single institution from 2015 to 2020.. Complete noninvasive management encompassed pelvic exam, ultrasound, and progestin treatment before or in conjunction with the endometrial sampling of diagnosis. Multivariable logistic and ordinal odds models were used to evaluate predictors and outcomes. Results: 152 subjects were included, 80.3 % with cancer and 19.7 % with atypical hyperplasia. The majority of patients had anovulatory bleeding, obesityand recent health care. Only 20.4 % had complete nonvinvasive management, and only 12.5 % had complete noninvasive management or endometrial sampling within 2 months of presentation with abnormal bleeding. Class III obesity reduced the likelihood of complete assessment and increased time to sampling, while age 45 and up and parity reduced time to sampling. Most patients had partial workup but no progestin treatment and long intervals before endometrial sampling after presentation to a provider with abnormal bleeding. Incomplete workup correlated to worse cancer grade and stage. Conclusion: Despite high clinical risk and health care contact, most patients had insufficient gynecologic management preceding a diagnosis of endometrial malignancy. Inadequate care correlated to worse oncologic outcomes and demonstrates missed opportunities for early detection and prevention of endometrial cancer.

RESUMO

OBJECTIVE: Genetic testing for ovarian cancer (OC) patients is essential to consideration of PARP inhibitor therapy. To improve access, we piloted a Genetic Testing Station (GTS) allowing patients to have a same-day genetic testing visit facilitated by Genetic Counselor Assistants (GCAs) under the supervision of Genetic Counselors (GCs). METHODS: The GTS was implemented December 2018 and operated through February 2020. Gynecologic Oncologists offered ovarian cancer patients a same-day GTS visit with a GCA. The patient received education via videos designed by GCs and then provided consent, a brief family history, and a sample for a standardized 133-gene panel. Results were provided by a GC. Patients were retrospectively identified by querying the medical record for OC patients seen 12 months prior to and 18 months after GTS implementation. RESULTS: A total of 482 patients pre-GTS were compared to 625 patients post-GTS. Genetic testing increased from 68.5% to 75.4% (p = 0.012) after implementation, primarily in patients with epithelial histologies (80% vs 89% in pre-GTS vs post-GTS, p = 0.005). Time from referral for genetic testing to obtaining results was evaluated in the post-GTS cohort, comparing patients who had traditional counseling to those who utilized the GTS. Time to obtaining results was 21 days in the GTS group (95% CI [10, 34]) compared to 56 days (95% CI [41,76]) in the traditional genetic counseling group. CONCLUSIONS: The GTS reduces barriers to care and facilitates discussion of precision treatment within a timely fashion while optimizing GC clinic time. Access improvement remains integral to improving uptake of genetic testing.

RESUMO

BACKGROUND: Combination therapy with radioembolization (yttrium-90)-resin microspheres) followed by nivolumab has shown a promising response rate of 30.6% in a Phase II trial (CA209-678) for advanced hepatocellular carcinoma (HCC); however, the response mechanisms and relevant biomarkers remain unknown. METHODS: By collecting both pretreatment and on-treatment samples, we performed multimodal profiling of tissue and blood samples and investigated molecular changes associated with favorable responses in 33 patients from the trial. RESULTS: We found that higher tumor mutation burden, NCOR1 mutations and higher expression of interferon gamma pathways occurred more frequently in responders. Meanwhile, non-responders tended to be enriched for a novel Asian-specific transcriptomic subtype (Kaya_P2) with a high frequency of chromosome 16 deletions and upregulated cell cycle pathways. Strikingly, unlike other cancer types, we did not observe any association between T-cell populations and treatment response, but tumors from responders had a higher proportion of CXCL9+/CXCR3+ macrophages. Moreover, biomarkers discovered in previous immunotherapy trials were not predictive in the current cohort, suggesting a distinctive molecular landscape associated with differential responses to the combination therapy. CONCLUSIONS: This study unraveled extensive molecular changes underlying distinctive responses to the novel treatment and pinpointed new directions for harnessing combination therapy in patients with advanced HCC.

RESUMO

PURPOSE: Pain, fatigue, sleep disturbance, and depression are four of the most common symptoms in patients with gynecologic cancer. The purposes were to identify subgroups of patients with distinct co-occurring pain, fatigue, sleep disturbance, and depression profiles (i.e., pre-specified symptom cluster) in a sample of patients with gynecologic cancer receiving chemotherapy and assess for differences in demographic and clinical characteristics, as well as the severity of other common symptoms and QOL outcomes among these subgroups. METHODS: Patients completed symptom questionnaires prior to their second or third cycle of chemotherapy. Latent profile analysis was used to identify subgroups of patients using the pre-specified symptom cluster. Parametric and nonparametric tests were used to evaluate for differences between the subgroups. RESULTS: In the sample of 233 patients, two distinct latent classes were identified (i.e., low (64.8%) and high (35.2%)) indicating lower and higher levels of symptom burden. Patients in high class were younger, had child care responsibilities, were unemployed, and had a lower annual income. In addition, these women had a higher body mass index, a higher comorbidity burden, and a lower functional status. Patients in the high class reported higher levels of anxiety, as well as lower levels of energy and cognitive function and poorer quality of life scores. CONCLUSIONS: This study identified a number of modifiable and non-modifiable risk factors associated with membership in the high class. Clinicians can use this information to refer patients to dieticians and physical therapists for tailored interventions.

RESUMO

OBJECTIVE: To evaluate the effect of risk-reducing salpingo-oophorectomy (RRSO) on change in bone mineral density (BMD) in women aged 34-50 years with pathogenic variants in BRCA1 or BRCA2 ( BRCA1 /2). METHODS: The PROSper (Prospective Research of Outcomes after Salpingo-oophorectomy) study is a prospective cohort of women aged 34-50 years with BRCA1 or two germline pathogenic variants that compares health outcomes after RRSO to a non-RRSO control group with ovarian conservation. Women aged 34-50 years, who were planning either RRSO or ovarian conservation, were enrolled for 3 years of follow-up. Spine and total hip BMD were measured by dual-energy X-ray absorptiometry (DXA) scans obtained at baseline before RRSO or at the time of enrollment for the non-RRSO group, and then at 1 and 3 years of study follow-up. Differences in BMD between the RRSO and non-RRSO groups, as well as the association between hormone use and BMD, were determined by using mixed effects multivariable linear regression models. RESULTS: Of 100 PROSper participants, 91 obtained DXA scans (RRSO group: 40; non-RRSO group: 51). Overall, total spine, and hip BMD decreased significantly from baseline to 12 months after RRSO (estimated percent change -3.78%, 95% CI -6.13% to -1.43% for total spine; -2.96%, 95% CI -4.79% to -1.14% for total hip) and at 36 months (estimated percent change -5.71%, 95% CI -8.64% to -2.77% for total spine; -5.19%, 95% CI -7.50% to -2.87% for total hip. In contrast, total spine and hip BMD were not significantly different from baseline for the non-RRSO group. The differences in mean percent change in BMD from baseline between the RRSO and non-RRSO groups were statistically significant at both 12 and 36 months for spine BMD (12-month difference -4.49%, 95% CI -7.67% to -1.31%; 36-month difference -7.06%, 95% CI -11.01% to -3.11%) and at 36 months for total hip BMD (12-month difference -1.83%, 95% CI -4.23% to 0.56%; 36-month difference -5.14%, 95% CI -8.11% to -2.16%). Across the study periods, hormone use was associated with significantly less bone loss at both the spine and hip within the RRSO group compared with no hormone use ( P <.001 at both 12 months and 36 months) but did not completely prevent bone loss (estimated percent change from baseline at 36 months -2.79%, 95% CI -5.08% to -0.51% for total spine BMD; -3.93%, 95% CI -7.27% to -0.59% for total hip BMD). CONCLUSION: Women with pathogenic variants in BRCA1 /2 who undergo RRSO before the age of 50 years have greater bone loss after surgery that is clinically significant when compared with those who retain their ovaries. Hormone use mitigates, but does not eliminate, bone loss after RRSO. These results suggest that women who undergo RRSO may benefit from routine screening for BMD changes to identify opportunities for prevention and treatment of bone loss.

RESUMO

OBJECTIVES: In a sample of patients with gynecologic cancers who are receiving chemotherapy, subgroups of patients with distinct state anxiety profiles were identified, and differences among the subgroups in demographic and clinical characteristics, stress, exposure to stressful life events, resilience, and coping behaviors were evaluated. DATA SOURCES: Patients (n = 230) completed questionnaires six times over two chemotherapy cycles. State anxiety was measured using the Spielberger State Anxiety Inventory. Subgroups of patients with distinct state anxiety profiles were identified using latent profile analysis. Differences among the classes were assessed using parametric and nonparametric tests. CONCLUSION: Three distinct state anxiety profiles were identified: low (55.2%), moderate (38.3%), and very high (6.5%). Compared with the low class, persons in the other two classes had lower functional status, more comorbidities, higher perceived stress, and lower resilience and were more likely to report a history of depression and to use disengagement coping strategies. Compared with the low class, the very high class was more likely to report childcare responsibilities; have a history of lung disease, stomach disease, or low back pain; have experienced physical neglect, serious money problems, a serious disaster, or foster care; or were a caregiver for someone with a severe disability. IMPLICATIONS FOR NURSING PRACTICE: Nearly 45% of patients reported clinically meaningful levels of state anxiety that persisted over two cycles of chemotherapy. Experiences with a variety of stressors may be risk factors for higher levels of anxiety during chemotherapy. Clinicians need to perform comprehensive social histories and assess for anxiety in patients receiving chemotherapy.

RESUMO

Objective: To describe the evolution of perioperative opioid management in gynecologic oncology patients after open surgeries and determine current opioid over-prescription rates. Methods: Part one of this two-part study was a retrospective chart review of adult patients who underwent laparotomy by a gynecologic oncologist from July 1, 2012 to June 30, 2021, comparing changes in clinical characteristics, pain management and discharge opioid prescription sizes between fiscal year 2012 (FY2012) and 2020 (FY2020). In part two, we prospectively surveyed patients after laparotomy in 2021 to determine opioid use after hospital discharge. Results: 1187 patients were included in the chart review. Demographic and surgical characteristics remained stable from FY2012 to FY2020 with differences notable for increased rates of interval cytoreductive surgeries for advanced ovarian cancer and decreased rates of full lymph node dissection. Median inpatient opioid use decreased by 62 % from FY2012 to FY2020. Median discharge opioid prescription size was 675 oral morphine equivalents (OME) per patient in FY2012 and decreased by 77.7 % to 150 OME in FY2020. Of 95 surveyed patients in 2021, median self-reported opioid use after discharge was 22.5 OME. Patients had an excess of opioids equivalent to 1331 doses of 5-milligram oxycodone tablets per 100 patients. Conclusion: Inpatient opioid use in our gynecologic oncology open surgical patients and post-discharge opioid prescription size significantly decreased over the last decade. Despite this progress, our current prescribing patterns continue to significantly overestimate patients' actual opioid use after hospital discharge. Individualized point of care tools are needed to determine an appropriate opioid prescription size.

RESUMO

Mis-sense mutations affecting TP53 promote carcinogenesis both by inactivating tumor suppression, and by conferring pro-carcinogenic activities. We report here that p53 DNA-binding domain (DBD) and transactivation domain (TAD) mis-sense mutants unexpectedly activate pro-carcinogenic epidermal growth factor receptor (EGFR) signaling via distinct, previously unrecognized molecular mechanisms. DBD- and TAD-specific TP53 mutants exhibited different cellular localization and induced distinct gene expression profiles. In multiple tissues, EGFR is stabilized by TAD and DBD mutants in the cytosolic and nuclear compartments respectively. TAD mutants promote EGFR-mediated signaling by enhancing EGFR interaction with AKT via DDX31 in the cytosol. Conversely, DBD mutants maintain EGFR activity in the nucleus, by blocking EGFR interaction with the phosphatase SHP1, triggering c-Myc and Cyclin D1 upregulation. Our findings suggest that p53 mutants carrying gain-of-function, mis-sense mutations affecting two different domains form new protein complexes that promote carcinogenesis by enhancing EGFR signaling via distinctive mechanisms, exposing clinically relevant therapeutic vulnerabilities.

RESUMO

BACKGROUND: Study 10, a four-part Phase 1/2 study, evaluated oral rucaparib monotherapy in patients with advanced solid tumours. Here we report the final efficacy and safety results in heavily pretreated patients with ovarian cancer who received rucaparib in Study 10 Parts 2A and 2B. METHODS: Parts 2A and 2B (Phase 2 portions) enrolled patients with relapsed, high-grade, platinum-sensitive or platinum-resistant, BRCA-mutated ovarian cancer who had received 2-4 (Part 2A) or 3-4 (Part 2B) prior chemotherapies. Patients received oral rucaparib 600 mg twice daily (starting dose). The primary endpoint was the investigator-assessed objective response rate (ORR) by RECIST v1.1. RESULTS: Fifty-four patients were enrolled: 42 in Part 2A (all had platinum-sensitive disease) and 12 in Part 2B (4 with platinum-sensitive disease; 8 with platinum-resistant disease). ORR was 59.3% (95% CI 45.0-72.4%). The median time to onset of the most common nonhaematological treatment-emergent adverse events (TEAEs) was typically early (<56 days) and was later for haematological TEAEs (53-84 days). The median duration of grade ≥3 TEAEs was ≤13 days. CONCLUSIONS: In patients with relapsed, platinum-sensitive or platinum-resistant germline BRCA-mutant high-grade ovarian cancer who had received ≥2 prior chemotherapies, rucaparib had robust antitumour activity with a safety profile consistent with prior reports. CLINICAL TRIAL REGISTRATION: NCT01482715.
