    The Effect of Treatment With Hyaluronic Acid Dermal Fillers on Skin Changes and Quality of Life in Oncology Patients

    by Eden Bar, Eliya Shachar, Ofir Artzi, Lyri Adar, Omer Shani, Adi Diner, Lee Pantanowitz Mabjeesh, Ido Wolf, Tamar Safra

    Background: Patients treated with cancer therapies often experience changes in physical appearance, body image perception, and self‐esteem, which influence their quality of life (QoL). Aims: To assess the effect of treatment with hyaluronic acid (HA) dermal fillers on QoL, safety, and perceived skin changes of oncology patients. Methods: A single‐center prospective study conducted between 2021 and 2023 among female oncology patients aged 30–70 years receiving active cancer treatment. All participants completed a questionnaire describing their demographics, disease history, and experience with aesthetic procedures, their intention to undergo aesthetic treatments, and a QoL questionnaire. A subset of participants received treatment with HA fillers. The effect of filler treatment on facial skin features, efficacy, and safety was evaluated by independent dermatologists and by the participants 8–12 weeks after the intervention. Results: In total, 127 women (median age 57.1 years) with breast (58.3%), gynecological (33.9%), and other cancer types (7.9%) entered the study. Most participants (84.0%) reported no previous treatment with dermal fillers. Thirty‐one participants received a single treatment with HA dermal fillers concurrently with cancer treatment and an optional touch‐up 4 weeks later. At follow‐up, statistically significant improvements in overall aesthetic facial appearance and specific skin quality parameters were observed. Mean QoL significantly improved, with notable improvements in self‐esteem, self‐perception, and overall participant feeling. Adverse events were minimal. Thirteen participants (41.9%) experienced mild dermal events. One participant developed a grade 1 delayed inflammatory reaction 6 months postinjection. Conclusions: HA fillers have the potential to improve QoL and self‐perception among oncology patients undergoing active cancer therapy.

    Effectiveness and safety of standard chemotherapy in older patients with ovarian cancer: a retrospective analysis by age group and treatment regimen

    by Miriam R. Brezis, Eliya Shachar, Shira Peleg Hasson, Ido Laskov, Nadav Michaan, Bar Levy, Ido Wolf, Tamar Safra

    Objective: To evaluate the effectiveness and safety of standard chemotherapy administered to patients >70 years with advanced ovarian cancer (OC).Methods: Medical records of 956 advanced-stage patients with OC treated between 2002-2020 with standard surgery and paclitaxel-carboplatin chemotherapy in a three-weekly (PC-3W) or weekly (PC-1W) regimen were reviewed. Treatment response and tolerability were compared between patients ≤70 years (N=723) and >70 years (N=233) with stratification to septuagenarians (>70-80 years) and octogenarians (>80 years).Results: Median overall survival (mOS) in patients >70 was 41.26 months (95% confidence interval [Cl], 37.22-45.14) and median progression-free survival (mPFS) was 11.04 months (95% Cl, 8.97-15.74). No statistically significant differences in mPFS and mOS were observed between septuagenarians and octogenarians. Patients >70 treated with PC-1W versus PC-3W had significantly longer mOS (57.17 versus 30.00 months) and mPFS (19.09 versus 8.15 months). Toxicity rates were mostly similar between younger and older patients. Among patients >70 treated with PC-1W, the rate of neutropenia (75.7% versus 51.8%, p=0.0005), thrombocytopenia (41.0% versus 22.2%, p=0.0042) and anemia (78.1% versus 51.9%, p70 treated with PC-3W. Significantly more patients treated with PC-1W completed ≥6 chemotherapy cycles, suggesting better tolerability of this regimen.Conclusions: Older patients with OC may benefit from improved OS with reasonable toxicity if treated with standard chemotherapy. Older patients treated with PC-1W are more likely to complete the full chemotherapy course and survive longer compared with those treated with conventional PC-3W.

    Implementation of Comprehensive Genomic Profiling in Ovarian Cancer Patients: A Retrospective Analysis

    by Shira Peleg Hasson, Dov Hershkovitz, Lyri Adar, Miriam Brezis, Eliya Shachar, Rona Aks, Lee Galmor, Yuval Raviv, Shira Ben Neriah, Ofer Merimsky, et al.

    Comprehensive genomic profiling (CGP) allows for the detection of driver alterations at high resolution, but the limited number of approved targeted therapies and their high costs have contributed to its limited clinical utilization. We retrospectively compared data of 946 women with ovarian cancer (11.4% were referred to CGP, and 88.6% served as control) to examine whether CGP provides a prognosis benefit. Patient baseline parameters were similar between the groups. Cox regression analysis adjusted for age, disease stage at diagnosis, and recurrence status showed statistically significantly longer median overall survival (mOS) in the CGP group versus the control (73.4 versus 54.5 months, p < 0.001). Fifty-four patients (52.9%) had actionable mutations with potential treatments; twenty-six (48.2%) were treated with matched targeted therapy, showing a trend for longer mOS than the eighty-six women in the CGP group who were not given a suggested treatment (105.5 versus 63.6 months, p = 0.066). None of the genomic alterations predicted metastasis location. CCNE1 amplification and KRAS mutations were associated with shorter mOS. Patients with tumor mutation burden ≥4 mutations/megabase had longer mOS. High loss of heterozygosity was associated with longer mOS (99.0 versus 48.2 months, p = 0.004). CGP testing may provide both prognostic and predictive insights for treatment of patients with ovarian cancer. Prospective studies of larger cohorts are warranted.

    A Randomized, Phase III Trial to Evaluate Rucaparib Monotherapy as Maintenance Treatment in Patients With Newly Diagnosed Ovarian Cancer (ATHENA–MONO/GOG-3020/ENGOT-ov45)

    by Bradley J. Monk, Christine Parkinson, Myong Cheol Lim, David M. O'Malley, Ana Oaknin, Michelle K. Wilson, Robert L. Coleman, Domenica Lorusso, Paul Bessette, Sharad Ghamande, et al.

    PURPOSE: ATHENA (ClinicalTrials.gov identifier: NCT03522246 ) was designed to evaluate rucaparib first-line maintenance treatment in a broad patient population, including those without BRCA1 or BRCA2 (BRCA) mutations or other evidence of homologous recombination deficiency (HRD), or high-risk clinical characteristics such as residual disease. We report the results from the ATHENA–MONO comparison of rucaparib versus placebo. METHODS: Patients with stage III-IV high-grade ovarian cancer undergoing surgical cytoreduction (R0/complete resection permitted) and responding to first-line platinum-doublet chemotherapy were randomly assigned 4:1 to oral rucaparib 600 mg twice a day or placebo. Stratification factors were HRD test status, residual disease after chemotherapy, and timing of surgery. The primary end point of investigator-assessed progression-free survival was assessed in a step-down procedure, first in the HRD population (BRCA-mutant or BRCA wild-type/loss of heterozygosity high tumor), and then in the intent-to-treat population. RESULTS: As of March 23, 2022 (data cutoff), 427 and 111 patients were randomly assigned to rucaparib or placebo, respectively (HRD population: 185 v 49). Median progression-free survival (95% CI) was 28.7 months (23.0 to not reached) with rucaparib versus 11.3 months (9.1 to 22.1) with placebo in the HRD population (log-rank P = .0004; hazard ratio [HR], 0.47; 95% CI, 0.31 to 0.72); 20.2 months (15.2 to 24.7) versus 9.2 months (8.3 to 12.2) in the intent-to-treat population (log-rank P < .0001; HR, 0.52; 95% CI, 0.40 to 0.68); and 12.1 months (11.1 to 17.7) versus 9.1 months (4.0 to 12.2) in the HRD-negative population (HR, 0.65; 95% CI, 0.45 to 0.95). The most common grade ≥ 3 treatment-emergent adverse events were anemia (rucaparib, 28.7% v placebo, 0%) and neutropenia (14.6% v 0.9%). CONCLUSION: Rucaparib monotherapy is effective as first-line maintenance, conferring significant benefit versus placebo in patients with advanced ovarian cancer with and without HRD.

    Pembrolizumab in Patients With Microsatellite Instability–High Advanced Endometrial Cancer: Results From the KEYNOTE-158 Study

    by David M. O'Malley, Giovanni Mendonca Bariani, Philippe A. Cassier, Aurelien Marabelle, Aaron R. Hansen, Ana De Jesus Acosta, Wilson H. Miller, Tamar Safra, Antoine Italiano, Linda Mileshkin, et al.

    PURPOSE: Pembrolizumab demonstrated durable antitumor activity in patients with previously treated, advanced microsatellite instability–high or mismatch repair–deficient (MSI-H/dMMR) tumors, including endometrial cancer, in the nonrandomized, open-label, multicohort, phase II KEYNOTE-158 study ( NCT02628067 ). We report efficacy and safety outcomes for patients with MSI-H/dMMR endometrial cancer enrolled in KEYNOTE-158. METHODS: Eligible patients from cohorts D (endometrial cancer, regardless of MSI-H/dMMR status) and K (any MSI-H/dMMR solid tumor, except colorectal) with previously treated, advanced MSI-H/dMMR endometrial cancer received pembrolizumab 200 mg once every 3 weeks for 35 cycles. The primary end point was objective response rate per RECIST version 1.1 by independent central radiologic review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. RESULTS: As of October 5, 2020, 18 of 90 treated patients (20%) had completed 35 cycles of pembrolizumab and 52 (58%) had discontinued treatment. In the efficacy population (patients who received ≥ 1 dose of pembrolizumab and had ≥ 26 weeks of follow-up; N = 79), the median time from first dose to data cutoff was 42.6 (range, 6.4-56.1) months. The objective response rate was 48% (95% CI, 37 to 60), and median duration of response was not reached (2.9-49.7+ months). Median progression-free survival was 13.1 (95% CI, 4.3 to 34.4) months, and median overall survival was not reached (95% CI, 27.2 months to not reached). Among all treated patients, 76% had ≥ 1 treatment-related adverse event (grades 3-4, 12%). There were no fatal treatment-related events. Immune-mediated adverse events or infusion reactions occurred in 28% of patients (grades 3-4, 7%; no fatal events). CONCLUSION: Pembrolizumab demonstrated robust and durable antitumor activity and encouraging survival outcomes with manageable toxicity in patients with previously treated, advanced MSI-H/dMMR endometrial cancer.

    Patient-Reported Outcomes in Patients With PIK3CA-Mutated Hormone Receptor–Positive, Human Epidermal Growth Factor Receptor 2–Negative Advanced Breast Cancer From SOLAR-1

    by Eva Maria Ciruelos, Hope S. Rugo, Ingrid A. Mayer, Christelle Levy, Frédéric Forget, Juan Ignacio Delgado Mingorance, Tamar Safra, Norikazu Masuda, Yeon Hee Park, Dejan Juric, et al.

    PURPOSE: In the phase III SOLAR-1 trial ( NCT02437318 ), the PI3Kα-selective inhibitor and degrader alpelisib significantly improved median progression-free survival when added to fulvestrant in patients with phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha ( PIK3CA)–mutated, hormone receptor–positive, human epidermal growth factor receptor 2–negative advanced breast cancer. We assessed health-related quality of life using patient-reported outcome measures in these patients. MATERIALS AND METHODS: In the PIK3CA-mutant cohort, 341 patients were randomly assigned 1:1 to receive alpelisib 300 mg daily or placebo plus fulvestrant 500 mg on days 1 and 15 of cycle 1 and on day 1 of subsequent 28-day cycles. Patient-reported outcomes were evaluated with the European Organisation for Research and Treatment of Cancer QoL of Cancer Patients and Brief Pain Inventory-Short Form questionnaires. Changes from baseline and time to 10% deterioration were analyzed using repeated measurement models and Cox models, respectively. RESULTS: Global Health Status/QoL and functional status were maintained from baseline (mean changes < 10 points) in the alpelisib (overall change from baseline [95% CI], −3.50 [−8.02 to 1.02]) and placebo arms (overall change from baseline [95% CI], 0.27 [−4.48 to 5.02]). Overall treatment effect in Global Health Status/QoL was not significantly different between arms (−3.77; 95% CI, −8.35 to 0.80; P = .101). Time to 10% deterioration for Global Health Status/QoL was similar between arms (hazard ratio, 1.03; 95% CI, 0.72 to 1.48). Compared with placebo, deterioration in social functioning and in diarrhea, appetite loss, nausea or vomiting, and fatigue symptom subscales occurred with alpelisib. Numerical improvement in Worst Pain was observed with alpelisib versus placebo (42% v 32%, week 24; P = .090). CONCLUSION: In SOLAR-1, there was no statistical difference in deterioration of Global Health Status/QoL between arms, whereas symptom subscales favored placebo for diarrhea, appetite loss, nausea or vomiting, and fatigue, known side effects of alpelisib. Treatment decisions must consider efficacy and tolerability; taken with clinical efficacy, these results support the benefit-risk profile of alpelisib in patients with hormone receptor–positive, human epidermal growth factor receptor 2–negative PIK3CA-mutated advanced breast cancer.

    Weekly Carboplatin and Paclitaxel: A Retrospective Comparison with the Three-Weekly Schedule in First-Line Treatment of Ovarian Cancer

    by Tamar Safra, Barliz Waissengrin, Talya Levy, Ellie Leidner, Rotem Merose, Dianna Matcheyevsky, Dan Grisaru, Ido Laskov, Nadav Mishaan, Rotem Shayzaf, et al.

    Background: Conventional first-line combination therapy for ovarian cancer comprises 6 cycles of adjuvant or neoadjuvant carboplatin (AUC5-6) with paclitaxel (175 mg/m2) every 3 weeks (PC-3W). Weekly scheduling of paclitaxel may maximize its antiangiogenic effect and reduce adverse effects. We compared the efficacy and safety of PC-3W with a modified protocol of weekly paclitaxel 80 mg/m2 and weekly carboplatin AUC2 administered on days 1, 8, and 15 in a 28-day cycle (i.e., with 1 week off-treatment [PC-W]). Materials and Methods: Medical records of consecutive patients treated between 2000 and 2018 were reviewed; 707 patients were analyzed for demographic and clinical characteristics, effectiveness and toxicity. Results: PC-3W was administered to 402 patients (median age, 60.5 years) and PC-W to 305 patients (median age, 62.5 years). Most patients (91.4%) were diagnosed at stage III–IV. Notwithstanding a higher proportion of residual disease and older patients in the PC-W group, median progression-free survival was 21.4 months and 13.2 months for PC-W and PC-3W, respectively; median overall survival was 75.2 and 54.0 months for PC-W and PC-3W, respectively. Cox proportional hazards model indicated improved survival for patients treated with PC-W (hazard ratio, 0.54). Similar results were observed for older patients diagnosed at ≥75 years. PC-W demonstrated a better safety profile, with lower incidence of neuropathy, neutropenia, and alopecia. Conclusion: PC-W is as active and better tolerated than the standard PC-3W regimen. PC-W may serve as an alternative option for elderly or frail patients. Implications for Practice: Weekly scheduling of paclitaxel 80 mg/m2 and carboplatin AUC2, administered on days 1, 8, and 15 in a 28-day cycle (PC-W) for first-line therapy for advanced ovarian cancer, is as active and better tolerated than the standard regimen of carboplatin and paclitaxel (175 mg/m2) every 3 weeks (PC-3W). It is possible that the weekly holiday on day 21 in the PC-W regimen may ensure better completion rates (which may result in treatment delays for toxicity in PC-3W). The results of this retrospective analysis highlight the weekly regimen as a valid treatment option, especially for elderly patients and those with significant comorbidities.
