Experiences of patients with peritoneal carcinomatosis-related complex care needs and their caregivers.

BACKGROUND: Patients with peritoneal carcinomatosis (PC) frequently undergo palliative procedures, yet these patients and their caregivers report being unprepared to manage ostomies, drains, and other complex care needs at home. The purpose of this study was to characterize the unique needs of these patients and their caregivers during care transitions. METHODS: Patients completed measures of health status and advance care planning, caregivers completed measures of preparedness and burden, and all participants completed measures of depression and anxiety. Participants detailed their experiences in individual, semi-structured interviews. We analyzed data using descriptive statistics and conventional content analysis. RESULTS: Sixty-one patients and 39 caregivers completed baseline measures. Twenty-four (39.3%) patients acknowledged their terminal illness and seven (11.5%) had discussed end-of-life care preferences with clinicians. Most (26/39, 66.7%) caregivers provided daily care. Among caregivers who managed symptoms, few were taught how to do so (6/20, 30%). Seven patients (11.5%) and seven caregivers (17.9%) met case criteria for anxiety, while 15 patients (24.6%) and two caregivers (5.1%) met case criteria for depression. Interview participants described a diagnosis of PC as a turning point for which there is no road map and identified the need for health systems change to minimize suffering. CONCLUSION: Patients with PC and their caregivers are highly burdened by symptoms and care needs. Patients' prognostic understanding and advance care planning are suboptimal. Interventions that train patients with PC and their caregivers to perform clinical care tasks, facilitate serious illness conversations, and provide psychosocial support are needed.

Feasibility and acceptability of a nurse-led telehealth intervention (BOLSTER) to support patients with peritoneal carcinomatosis and their caregivers: A pilot randomized clinical trial.

OBJECTIVE: Patients with advanced gynecologic (GYN) and gastrointestinal (GI) cancers frequently develop peritoneal carcinomatosis (PC), which limits prognosis and diminishes health-related quality of life (HRQoL). Palliative procedures may improve PC symptoms, yet patients and caregivers report feeling unprepared to manage ostomies, catheters, and other complex needs. Our objectives were to (1) assess the feasibility of an efficacy trial of a nurse-led telehealth intervention (BOLSTER) for patients with PC and their caregivers; and (2) assess BOLSTER's acceptability, potential to improve patients' HRQoL and self-efficacy, and potential impact on advance care planning (ACP). METHODS: Pilot feasibility RCT. Recently hospitalized adults with advanced GYN and GI cancers, PC, and a new complex care need and their caregivers were randomized 1:1 to BOLSTER or enhanced discharge planning (EDP). We defined feasibility as a ≥ 50% approach-to-consent ratio and acceptability as ≥70% satisfaction with BOLSTER. We assessed patients' HRQoL and self-efficacy at baseline and six weeks, then compared the proportion experiencing meaningful improvements by arm. ACP documentation was identified using natural language processing. RESULTS: We consented 77% of approached patients. In the BOLSTER arm, 91.0% of patients and 100.0% of caregivers were satisfied. Compared to EDP, more patients receiving BOLSTER experienced improvements in HRQoL (68.4% vs. 40.0%) and self-efficacy for managing symptoms (78.9% vs. 35.0%) and treatment (52.9% vs. 42.9%). The BOLSTER arm had more ACP documentation. CONCLUSIONS: BOLSTER is a feasible and acceptable intervention with the potential to improve patients' HRQoL and promote ACP. An efficacy trial comparing BOLSTER to usual care is underway. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03367247; PI: Wright.

Vulvar Cancer, Version 3.2024, NCCN Clinical Practice Guidelines in Oncology.

Vulvar cancer is annually diagnosed in an estimated 6,470 individuals and the vast majority are histologically squamous cell carcinomas. Vulvar cancer accounts for 5% to 8% of gynecologic malignancies. Known risk factors for vulvar cancer include increasing age, infection with human papillomavirus, cigarette smoking, inflammatory conditions affecting the vulva, and immunodeficiency. Most vulvar neoplasias are diagnosed at early stages. Rarer histologies exist and include melanoma, extramammary Paget's disease, Bartholin gland adenocarcinoma, verrucous carcinoma, basal cell carcinoma, and sarcoma. This manuscript discusses recommendations outlined in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for treatments, surveillance, systemic therapy options, and gynecologic survivorship.

Pilot randomized trial of an acceptance-based telehealth intervention for women with ovarian cancer and PARP inhibitor-related fatigue.

OBJECTIVE: Poly(ADP-ribose) polymerase inhibitors (PARPi) have dramatically changed treatment for advanced ovarian cancer, but nearly half of patients experience significant fatigue. We conducted a two-site pilot randomized trial to evaluate the feasibility, acceptability, and preliminary efficacy of a brief, acceptance-based telehealth intervention (REVITALIZE) designed to reduce fatigue interference in patients on PARPi. METHODS: From June 2021 to April 2022, 44 participants were randomized 1:1 to REVITALIZE (6 weekly one-on-one sessions+booster) or enhanced usual care. Feasibility was defined as: ≥50% approach-to-consent among potentially eligible patients and ≥70% completion of 12-week follow-up assessment; acceptance was <20% participants reporting burden and <20% study withdrawal. Fatigue, anxiety, depression, and quality of life were assessed at baseline, 4-, 8- and 12-weeks. RESULTS: Among 44 participants (mean age = 62.5 years, 81.8% stage III/IV disease), the study was feasible (56.4% approach-to-consent ratio, 86.3% completion of 12-week assessment) and acceptable (0% reporting burden, 11.3% study withdrawal). At 12-week follow-up, REVITALIZE significantly reduced fatigue interference (Cohen's d = 0.94, p = .008) and fatigue severity (d = 0.54, p = .049), and improved fatigue levels (d = 0.62, p = .04) relative to enhanced usual care. REVITALIZE also showed promise for improved fatigue self-efficacy, fatigue catastrophizing, anxiety, depression, and quality of life (ds = 0.60-0.86, p ≥ .05). Compared with enhanced usual care, REVITALIZE participants had fewer PARPi dose reductions (6.7% vs. 19.0%), and dose delays (6.7% vs. 23.8%). CONCLUSIONS: Among fatigued adults with ovarian cancer on PARPi, a brief, acceptance-based telehealth intervention was feasible, acceptable, and demonstrated preliminary efficacy in improving fatigue interference, severity, and levels. REVITALIZE is a novel, scalable telehealth intervention worthy of further investigation.

Uterine Neoplasms, Version 1.2023, NCCN Clinical Practice Guidelines in Oncology.

Adenocarcinoma of the endometrium (also known as endometrial cancer, or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. It is estimated that 65,950 new uterine cancer cases will have occurred in 2022, with 12,550 deaths resulting from the disease. Endometrial carcinoma includes pure endometrioid cancer and carcinomas with high-risk endometrial histology (including uterine serous carcinoma, clear cell carcinoma, carcinosarcoma [also known as malignant mixed Müllerian tumor], and undifferentiated/dedifferentiated carcinoma). Stromal or mesenchymal sarcomas are uncommon subtypes accounting for approximately 3% of all uterine cancers. This selection from the NCCN Guidelines for Uterine Neoplasms focuses on the diagnosis, staging, and management of pure endometrioid carcinoma. The complete version of the NCCN Guidelines for Uterine Neoplasms is available online at NCCN.org.

Examining associations between symptoms of eating disorders and symptoms of anxiety, depression, suicidal ideation, and perceived family functioning in university students: A brief report.

OBJECTIVE: We examined the relationships between eating disorders symptoms (EDs), suicidal ideation, depressive and anxiety symptoms, and perceived family functioning in a sample of university students aged 18-25 years (N = 397). METHOD: Assessment of symptoms was carried out with the Eating Disorder Diagnostic Scale, Beck Anxiety Inventory and Beck Depression Inventory, among others. We explored the associations between the domains using network analysis. RESULTS: We found that physical anxiety symptoms, followed by cognitive and physical depressive symptoms showed the greatest centrality in the current network. Perceived family functioning was negatively related to eating disorder symptoms. DISCUSSION: We provide evidence regarding the relevant role of anxiety and depression symptoms in the presentation of ED symptoms in university students. These findings provide new insights to improve preventive interventions to timely reduce symptoms and risk factors associated with EDs. PUBLIC SIGNIFICANCE: Using a network approach, we found specific associations between physical anxiety symptoms, cognitive and physical depressive symptoms, eating disorders symptoms, suicidal ideation and perceived family functioning in university students. These variables can be potential targets to develop evidence-based preventive strategies in this population. A better understanding of these complex associations and the role of family variables could enhance the effectiveness of interventions in both clinical and educational settings.

Combined PARP and HSP90 inhibition: preclinical and Phase 1 evaluation in patients with advanced solid tumours.

PURPOSE: PARP inhibitor resistance may be overcome by combinatorial strategies with agents that disrupt homologous recombination repair (HRR). Multiple HRR pathway components are HSP90 clients, so that HSP90 inhibition leads to abrogation of HRR and sensitisation to PARP inhibition. We performed in vivo preclinical studies of the HSP90 inhibitor onalespib with olaparib and conducted a Phase 1 combination study. PATIENTS AND METHODS: Tolerability and efficacy studies were performed in patient-derived xenograft(PDX) models of ovarian cancer. Clinical safety, tolerability, steady-state pharmacokinetics and preliminary efficacy of olaparib and onalespib were evaluated using a standard 3 + 3 dose-escalation design. RESULTS: Olaparib/onalespib exhibited anti-tumour activity against BRCA1-mutated PDX models with acquired PARPi resistance and PDX models with RB-pathway alterations(CDKN2A loss and CCNE1 overexpression). Phase 1 evaluation revealed that dose levels up to olaparib 300 mg/onalespib 40 mg and olaparib 200 mg/onalespib 80 mg were safe without dose-limiting toxicities. Coadministration of olaparib and onalespib did not appear to affect the steady-state pharmacokinetics of either agent. There were no objective responses, but disease stabilisation ≥24 weeks was observed in 7/22 (32%) evaluable patients including patients with BRCA-mutated ovarian cancers and acquired PARPi resistance and patients with tumours harbouring RB-pathway alterations. CONCLUSIONS: Combining onalespib and olaparib was feasible and demonstrated preliminary evidence of anti-tumour activity.

A randomized phase II trial of bevacizumab vs. bevacizumab and erlotinib as first-line consolidation after carboplatin, paclitaxel, and bevacizumab in newly diagnosed patients with mullerian tumors.

BACKGROUND: The combination of paclitaxel to platinum remains the backbone of therapy in patients with advanced Mullerian tumors. In patients with newly diagnosed Mullerian tumors, we investigated the progression-free survival benefit of bevacizumab and bevacizumab and erlotinib as consolidation therapy post-induction therapy. METHODS: Sixty patients were enrolled in a phase II trial of carboplatin, paclitaxel, and bevacizumab (induction therapy). After the completion induction therapy, patients were stratified by response (≥ SD) and then randomized (1:1) to either bevacizumab (A) or bevacizumab and erlotinib (AE.) The primary endpoint was PFS. Secondary endpoints included the response rate of induction and consolidation therapy and toxicity profile of each consolidative arm. Each consolidative arm was compared to the historical control GOG 111. RESULTS: Forty-eight patients advanced to the consolidative phase of the trial. Twelve patients were removed in the induction phase, the majority for toxicity. The most common toxicity (grade ≥ 3) was diarrhea (20%: arm AE; 0%: arm A). One patient in the AE arm had a fatal cardiac arrest deemed unrelated to the study treatment. No gastrointestinal perforations were reported. The median PFS in the AE and A arm was 18.9 months (p < 0.0001) and 13.3 months (p: ns), respectively. The overall rate of grade 3/4 toxicities in the AE arm was 72% and in the A arm 30%. Six patients remain free of disease 10 years after enrollment. CONCLUSION: Combinatorial consolidation therapy with AE was associated with an improved progression-free survival in patients with Mullerian tumors.

Next-Generation Sequencing in the Diagnosis of Metastatic Lesions: Reclassification of a Glioblastoma as an Endometrial Cancer Metastasis to the Brain.

Endometrial cancer is the most common gynecologic cancer in the U.S., but metastasis to the brain is rare, and diagnosis can be challenging. Traditional tools for determining if a tumor is a primary or metastatic lesion include pan-imaging, histopathologic studies, and immunohistochemistry. Molecular testing with next-generation sequencing has been increasingly used to augment these tests. We present a case of a patient who initially presented with a brain lesion diagnosed as glioblastoma on histology and immunohistochemistry, but whose diagnosis was later changed to metastasis from an endometrial primary based on molecular findings. The two tumors shared a common microsatellite instability signature and 51 DNA variants, including oncogenic driver mutations KRAS p.G13D, PIK3CA p.E545A, and PTEN p.I135V and p.K267Rfs*9. This highlights the power of molecular analysis in making the diagnosis in cases of rare metastases. KEY POINTS: Brain metastasis from endometrial primary is rare, and histopathological features may be augmented with molecular analysis to aid in diagnosis. Comparison of the molecular makeup of the primary endometrial lesion with the metastatic lesion may reveal high-risk molecular features that may be indicative of metastatic potential.

Stepping into survivorship pilot study: Harnessing mobile health and principles of behavioral economics to increase physical activity in ovarian cancer survivors.

OBJECTIVE: Physical activity improves physical function, quality of life, and mental health, yet fewer than 80% of ovarian cancer survivors meet activity guidelines. This pilot intervention study aimed to increase physical activity in ovarian cancer survivors by leveraging principles of behavioral economics, gamification, and social support. METHODS: This 24-week study (12-week intervention; 12-week follow-up) enrolled women with ovarian cancer after completion of first-line treatment with a self-selected "teammate." Participants used Fitbits to measure daily steps, select an increased step goal, and enroll in a collaborative game, including points and levels for achieving step goals. Primary outcomes were feasibility (defined a priori as ≥60% approach-to-consent ratio and ≥ 70% adherence to Fitbit), acceptability (≤20% of participants reporting burden or regret for participation) and preliminary efficacy (≥70% reporting increased motivation); exploratory outcomes included change in steps. RESULTS: We recruited 24 participants (mean age = 63 years, range = 37-79 years) with a 94% approach-to-consent ratio. All participants completed the intervention with 94% tracker adherence. At 24-week follow-up, 1/24 (≤5%) of participants reported burden; 0/24 (0%) reported regret for study participation; and 22/24 (>90%) agreed/strongly agreed that "the study motivated me to increase activity levels." Participants' mean daily steps were 6210.7 (±3328.1) at baseline and increased to 7643 (± 3610.9) steps (p < 0.001) during the 12-week intervention. CONCLUSIONS: This pilot study demonstrated feasibility, acceptability, and preliminary efficacy, justifying a larger randomized clinical trial to test efficacy at increasing activity levels. Future studies should examine strategies for maintaining increased activity levels in survivors over time.

Sequential Phase II clinical trials evaluating CRLX101 as monotherapy and in combination with bevacizumab in recurrent ovarian cancer.

BACKGROUND: Topoisomerase-1 inhibitors are an important class of cytotoxics associated with toxicity that limits their use. CRLX101 is a novel cyclodextrin-containing polymer conjugate of camptothecin (CPT) that self-assembles into nanoparticles to deliver sustained levels of active CPT into cancer cells while substantially reducing systemic exposure. METHODS: We conducted sequential phase II, open label, single arm clinical trials to evaluate CRLX101 as a single agent (n = 29) and with bevacizumab (Bev) (n = 34). Patients (pts) had measurable recurrent epithelial ovarian, tubal or primary peritoneal cancer, that could be platinum refractory, resistant or sensitive. Cohort A (Single agent CRLX101) allowed up to 3 prior chemotherapy regimens, but no prior topo-1 inhibitors. Pts received CRLX101 15 mg/m2 IV every 14 days Q28 with response evaluation every 2 cycles. Cohort B also received Bev 10 mg/kg D1,15 Q28, and included only platinum resistant disease with up to 2 prior lines, and more rigorous eligibility criteria. RESULTS: CRLX101 was well tolerated other than nausea, fatigue and anemia. 29 pts. received a median of 3 (1-16) cycles with a clinical benefit rate (CBR) of 68% and overall response rate (ORR) of 11%. With the addition of Bev in Cohort B (n = 34), the CBR was increased to 95% and the ORR to 18%. PFS was 4.5 months (0.9 to 15.9 months) in Cohort A and 6.5 months (2.8 to 14.4 months) in Cohort B. Bev increased the incidence of hypertension and qualitatively increased bladder toxicities, but without SAEs. CONCLUSIONS: CRLX101 meets the clinical need for an effective and tolerable topoisomerase I inhibitor and can be safely combined with bevacizumab.

Ofranergene obadenovec (VB-111) in platinum-resistant ovarian cancer; favorable response rates in a phase I/II study are associated with an immunotherapeutic effect.

OBJECTIVE: Report final results of a phase I/II study of VB-111, a targeted anti-cancer gene therapy with a dual mechanism: anti angiogenic/vascular disruption and induction of an anti-tumor directed immune response, in combination with paclitaxel in patients with platinum-resistant ovarian cancer. METHODS: Study NCT01711970 was a prospective, open label, dose escalation study assessing combination treatment of VB-111 and weekly paclitaxel. In the Phase I part of the study, patients were treated with escalating doses of intravenous VB-111 and paclitaxel. In Phase 2, patients were treated with therapeutic doses of VB-111 and paclitaxel 80 mg/m2. Assessments included safety, overall survival (OS), progression free survival (PFS), and tumor response (CA-125 and RECIST). RESULTS: 21 patients with recurrent platinum-resistant ovarian cancer were enrolled. 17/21 received the therapeutic dose. Patients had a median of 3 prior lines of therapy. Half of the subjects were platinum refractory, and half were previously treated with antiangiogenics. No DLTs were observed. VB-111 was well tolerated and associated with mild flu-like symptoms. In the therapeutic dose cohort, a 58% CA-125 GCIG response rate was seen in evaluable patients. The median OS was 16.6 months in patients treated with therapeutic dose compared to 5.8 months in sub-therapeutic dose (p = 0.028). Tumor specimens taken after treatment demonstrated tumor infiltrated with cytotoxic CD8 T-cells in regions of apoptotic cancer cells. CONCLUSIONS: Treatment with VB-111 in combination with paclitaxel was safe and well tolerated. Favorable tumor responses and overall survival outcomes were associated with induction of an immunotherapeutic effect.

Combined pembrolizumab and pegylated liposomal doxorubicin in platinum resistant ovarian cancer: A phase 2 clinical trial.

OBJECTIVE: Pegylated liposomal doxorubicin (PLD) in vitro may have immunomodulatory abilities and preclinical evidence suggests it synergizes with immune checkpoint blockade. We hypothesized that combining PLD and pembrolizumab would be active in patients with platinum-resistant ovarian cancer (PROC). METHODS: This was a single-arm, multi-center phase II trial. Eligible patients had PROC with ≤2 prior lines of cytotoxic therapy for recurrent or persistent disease. Twenty-six patients were enrolled and given pembrolizumab 200 mg intravenously (IV) every 3 weeks and PLD 40 mg/m2 IV every 4 weeks. Patients were assessed radiographically every 8 weeks. The primary endpoint was clinical benefit rate (CBR), defined as complete response (CR) + partial response (PR) + stable disease (SD) ≥24 weeks. The study was powered to detect an improvement in CBR from 25% to 50%, with rejection of the null hypothesis if at least 10 patients achieved clinical benefit. T-cell inflamed gene expression profiles (GEP) and PD-L1 were assessed and correlated with clinical outcome. RESULTS: Twenty-three patients were evaluable for best overall response. The study satisfied its primary endpoint, with 12 patients achieving clinical benefit for a CBR of 52.2% (95% CI 30.6-73.2%). There were 5 PRs (21.7%) and 1 CR (4.3%), for an overall response rate (ORR) of 26.1%. Six patients had SD lasting at least 24 weeks. Combination therapy was well tolerated without unexpected toxicities. CONCLUSIONS: The combination of pembrolizumab and PLD was manageable, without unexpected toxicities, and showed preliminary evidence of clinical benefit in the treatment of platinum resistant ovarian cancer. ORR and median PFS of combination therapy in this study was higher than historical comparisons of PLD alone or anti-PD-1/PD-L1 agents alone. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT02865811.

NCCN Guidelines Insights: Cervical Cancer, Version 1.2020.

The NCCN Guidelines for Cervical Cancer provide recommendations for diagnostic workup, staging, and treatment of patients with the disease.

Results from a single arm, single stage phase II trial of trametinib and GSK2141795 in persistent or recurrent cervical cancer.

BACKGROUND: Improved treatment for advanced cervical cancer is needed; currently, treatment options include combined chemotherapy and bevacizumab or pembrolizumab monotherapy for PD-L1 positive disease. PIK3CA and KRAS mutations have been reported in cervical cancers; this study therefore tested dual inhibition of PI3K and RAS signaling by combining the MEK inhibitor trametinib and the AKT inhibitor GSK2141795 in recurrent cervical cancer. METHODS: This was an investigator-initiated phase II study combining trametinib and GSK2141795 in patients with recurrent cervical cancer. Primary endpoint was best tumor response; secondary endpoints included progression free survival, overall survival, and safety assessment. Translational objectives included characterization of molecular alterations in PI3K and RAS signaling pathway genes. RESULTS: Planned accrual was 35 patients; 14 patients were enrolled and received at least one dose of study drug before the study was terminated due to discontinuation of GSK2141795 development. There were no confirmed responses; 1 patient had an unconfirmed PR, 8 had stable disease, 3 had progression as best response, and 2 were unevaluable. Toxicities were mostly grade 1 and 2, although 57% of patients experienced grade 3/4 adverse events and 50% patients required a dose reduction. CONCLUSIONS: The combination of trametinib and GSK2141795 was feasible but required dose holds and modifications for adverse events; however, anti-cancer activity was minimal, even in patients with PI3K or RAS pathway alterations. Although the study was terminated early after GSK2141795 development was halted, the findings in these 14 patients do not support further development of this combination in cervical cancer.

Diagnosis and management of a recurrent polymerase-epsilon (POLE)-mutated endometrial cancer.

Polymerase-epsilon (POLE)-mutated carcinomas are a rare, but well-known subtype of endometrial cancer. While typically associated with good prognosis, recurrences are documented. Here we present a case of recurrent POLE-mutated endometrial cancer, discuss pathologic features, current methods of molecular classification, and explore therapeutic implications for the POLE-mutation phenotype.

Cervical Cancer, Version 3.2019, NCCN Clinical Practice Guidelines in Oncology.

Cervical cancer is a malignant epithelial tumor that forms in the uterine cervix. Most cases of cervical cancer are preventable through human papilloma virus (HPV) vaccination, routine screening, and treatment of precancerous lesions. However, due to inadequate screening protocols in many regions of the world, cervical cancer remains the fourth-most common cancer in women globally. The complete NCCN Guidelines for Cervical Cancer provide recommendations for the diagnosis, evaluation, and treatment of cervical cancer. This manuscript discusses guiding principles for the workup, staging, and treatment of early stage and locally advanced cervical cancer, as well as evidence for these recommendations. For recommendations regarding treatment of recurrent or metastatic disease, please see the full guidelines on NCCN.org.

Gestational Trophoblastic Neoplasia, Version 2.2019, NCCN Clinical Practice Guidelines in Oncology.
