High-dose Ifosfamide (HDIFX) as a 14-day continuous infusion (ci) in advanced adult soft tissue sarcoma (STS): A single- institution retrospective case series analysis

10067 Background: High-dose IFX (≥12 g/sqm) is active even in STS patients pretreated with standard-dose IFX, though with substantial toxicity. Prolonged continuous infusion, through a portable pump, may be an alternative way of administration. A Phase II study thereof is ongoing in Italy, but some pts have been treated off the study, either prior to its start or for practical reasons. Such consecutive pts seen at a single institution have been retrospectively reviewed. Methods: Between July 2001 and September 2006, 45 adult patients (M:F = 25:20; mean age 47 yrs; PS 0–1) with progressing advanced/metastatic STS, all previously treated with anthracyclines and standard-dose IFX, were given ciHDIFX, at the dose of 14 g/sqm as a 14-day continuous infusion every 4 weeks, using two portable infusional devices, with equidose Mesna, lasting 7 days each. Diagnosis was leyomiosarcoma in 12 patients, synovial sarcoma in 9, liposarcoma in 5, and other histological types in 19. Disease was advanced inoperable in 6 pts, and metastatic in 39. The total number of cycles was 176 (median number per pt: 4). Results: A PR was seen in 5 pts (synovial sarcoma, 2; leyomiosarcoma, 1, liposarcoma, 1; chondrosarcoma, 1), and SD in 22 (>6 mos in 12), for a clinical benefit rate = 37%. PFS at 6 months was 35%. Median PFS was 11 mos in pts with PR and 6 in those with SD. Median PFS was 8 months in 9 patients undergoing complete tumor resection. Most common side effects were nausea (G1–2 in 14 pts) and asthenia (G1–2 in 15 pts). G2 anemia was seen in 8 pts, G2 neutropenia in 6. One pt with a single kidney had a reversible G2 hypercreatininemia. No grade 3–4 toxicity were recorded. Conclusions: In this series, ciHDIFX was associated with a PR and 6-mos PFS rate in the range of active second-line agents in advanced STS. This regimen was exceedingly well tolerated. No significant financial relationships to disclose.

Abstract INTRODUCTION Observation alone vs adjuvant radiotherapy (RT) following gross total resection (GTR) of WHO Grade II (G2) meningiomas is controversial. Local recurrence (LR) rates have been reported to be similar. We present LR rates in patients who were observed following G2 meningioma resection and correlate with Simpson grades. METHODS Patients from 2005 to 2018 who underwent observation alone following surgical resection of G2 meningiomas at a single institution were analyzed in a retrospective case series. Simpson grades were used to classify extent of tumor resection. Patients were followed with magnetic resonance imaging (MRI) or computed tomography (CT) imaging at 1-mo, 3-mo, 6-mo, and 12-mo postoperatively, then annually thereafter to monitor for recurrence. Descriptive 2-yr, and 5-yr LR rates for our entire cohort and time to recurrence by Simpson grade are reported. RESULTS A total of 28 patients with Simpson 1 to 4 resections for G2 meningiomas did not undergo adjuvant RT and were included. Median follow-up (FU) was 34 mo [Interquartile range (IQR): 18-55 mo]. Median time to LR was 55 mo (IQR: 44-65 mo) across our entire cohort. Of 14 patients with Simpson 1 resection, there was 1 LR at 68 mo. Of 3 patients with Simpson 2 resection, there was 1 LR at 49 mo. Of 9 patients with Simpson 3 resection, there were 5 recurrences; median time to LR was 61 mo. Of 2 patients with Simpson 4 resections, there was 1 LR at 3 mo. Overall, 2-yr LR was 3.6% and 5-yr LR was 10.7%. There was no statistically significant difference in LR rate between Simpson 1 vs Simpson 2 to 4 resections (P = .11). CONCLUSION Our results are consistent with the low recurrence rate of G2 meningiomas undergoing observation along following GTR in current literature. Simpson grade 1 resections have low overall LR rate and larger scale studies are needed to determine if statistical significance exists.

Abstract Embryonal tumors with multilayer rosettes (ETMR) are rare and highly-aggressive central nervous system (CNS) neoplasms which occur primarily in young children and carry a dismal prognosis. To date, no large clinical investigations have been conducted to determine the optimal therapy for ETMR. Data from retrospective case series suggest that our most aggressive standard therapies are not sufficient for cure in the majority of cases. New treatment approaches incorporating pre-clinical data and the known biology of ETMR are therefore urgently needed. A German drug screen using the patient-derived ETMR BT183 cell line and its xenograft revealed anti-tumor activity of topotecan, doxorubicin, and actinomycin D; three agents used infrequently for treating infant CNS tumors. Additional results from a small series of ETMR patients suggest that optimization of induction chemotherapy using these active agents may improve response and survival outcomes. In 2019, an international panel of pediatric neuro-oncology experts convened to advance therapy for ETMR. A consensus protocol was developed incorporating maximal safe surgical resection, induction chemotherapy with active pre-clinical agents, intrathecal chemotherapy, radiotherapy, and high-dose chemotherapy. This international consensus protocol represents the first prospective clinical investigation specific to ETMR and will be available through a treatment registry globally and as a clinical trial at select centers. The study aims to improve survival by providing aggressive, optimized therapy for ETMR and will serve as a platform to explore new biologically-promising agents. The investigation will also provide valuable prospective outcome data and correlative biological studies to serve as baseline comparators for future clinical trials.

Introduction: Ultrasound biomicroscopy (UBM) is the only widely used method for the evaluation of anterior uveal melanoma (AUM). Objective: Documentation of regression of AUM treated with ruthenium-106 (Ru-106) plaque types CCB and CCC using UBM. Methods: This single institution-based retrospective case series involved 10 Caucasian patients with AUM followed after brachytherapy with UBM from January 2014 until February 2019. The largest prominence of the tumor perpendicular to the sclera or the cornea (including scleral/corneal thickness) (D) and the largest basal dimension (B) were measured in millimeters with UBM for all patients prior to the brachytherapy and at 4-month interval follow-up. Tumor regression was calculated as a percentage of decrease in the initial D and B values. Results: The study involved 10 patients with a mean age of 64.4 years (yr) (range 46–80 yr). D ranged from 1.82 to 5.5 mm (median 2.99 mm) and B from 2.32 to 12.38 mm (median 4.18 mm). The apical radiation dose in all patients was 100 Gy. The median follow-up was 42.02 months. Regression for D was 21.11 ± 13.66%, 31.09 ± 14.66%, and 34.92 ± 19.86% at 1st, 2nd, and 3rd year of the follow-up, respectively, while for B it was 21.58 ± 16.05%, 28.98 ± 17.71%, and 32.06 ± 18.96%, respectively. Tumor recurrence was documented in 2/10 patients. Conclusion: The major regression of AUM, treated with Ru-106 plaque types CCB and CCC, was documented in the first 2 years after brachytherapy in our study group. In the following years, only minimal regression was documented that warns of the need for close monitoring and active search for local recurrences.

End Stage

Total ankle replacement has become a viable alternative to ankle arthrodesis in the surgical management of advanced ankle arthritis. Total ankle replacement has generally been reserved for patients who are older and for those who will have a lower demand on the replacement. The purpose of the current study is to review patient outcomes, complications, and implant survival in patients younger than 55 years who underwent total ankle replacement at a single institution. A single-center chart and radiographic review was performed of consecutive patients who underwent total ankle replacement for treatment of end-stage ankle arthritis. All surgeries were performed by 1 of 5 fellowship-trained foot and ankle surgeons at a single institution. A total of 51 patients met inclusion criteria with a mean follow-up of 31.2 months (SD = 16.2). Implant survival was 94%, There were 7 major complications (13%) requiring an unplanned return to the operating room and 8 minor complications (15%) that resolved with conservative care. The results of this study show that total ankle replacement is a viable treatment option for patients younger than 55 years. Levels of Evidence: A retrospective case series

Objective: Standards for treatment of laryngeal clefts remain poorly defined. There are no large case series that report the efficacy of injection laryngoplasty (IL) in the treatment of pediatric Type 1 laryngeal clefts (LC-1). The objective of this study is to measure the effect of IL in young children with LC-1. Methods: A retrospective case series of 130 patients was completed over 3 years at a at a single institution included patients aged 1 month to 8 years, diagnosed with aspiration and penetration issues during swallowing based on a Videofluoroscopic Swallow Study (VFSS). Patients underwent surgical evaluation and intervention using carboxymethylcellulose gel injection. Collected data points included age in months at time of first injection, gender, race, pre- and post-operation VFSS scores, number of injections, co-morbidities and post-operative complications. VFSS scores were evaluated pre- and post-operatively to assess efficacy of intervention. A secondary outcome was efficacy in patients with aspiration compared to those with penetration alone. Results: This study included 77 male and 53 female patients. Sixty-two patients (48%) demonstrated a significant post-operative improvement in their swallowing function ( P < .05). There were no statistical differences in age, number of injections, or the volume of the first injection. Patients that showed a post-operative improvement in swallowing function were on average 5 months older and had more severe aspiration and penetration compared to those who did not demonstrate a post-operative benefit and underwent less injections. The volume of injection did not appear to play a role in the success rate. Conclusion: Injecting the inter-arytenoid area in patients with LC-1 appears to confer some benefit to close to half of our patient population. Successful procedures seemed to occur in patients with more severe aspiration and penetration and older age.

Early Postoperative Complications

Background There is limited data regarding postoperative complications after microtia surgery or tympanoplasty; however, complication rates after pinna reconstruction following tumor resection and comorbidities associated with suboptimal outcomes have not been investigated so far. Objective To examine the incidence of postoperative complications after auricular reconstruction surgery following tumor resection and determine the association between postoperative complications and defect size, patients’ comorbidities, and reconstruction type. Methods and Materials In a retrospective case series ( n = 146, January 2014 to October 2018), we examined the surgical outcome and amount of postoperative complications following auricular surgery as well as the association with different comorbidities. SPSS 16.0 was used for statistical analyses. Results The following early postoperative complications were identified: pain (29.5%), hematoma (4.1%), flap congestion (4.8%), infection (3.4%), and flap/graft necrosis (2.7%). Late complications including cartilage step-offs, helical rim sulcus alteration, granulomas, or ear deformities occurred only in 3.6% of subjects. Reconstructions of large defects (>1 cm2) were associated with a higher incidence of early postoperative complications compared to small defects (<1 cm2) ( P < .001). Neither the presence of smoking or diabetes nor immunosuppression was significantly linked to an increased incidence of early complications. Immunosuppression, however, was associated with a higher incidence of postoperative infection ( P < .001) Conclusion The incidence of early and late postoperative complications after skin tumor resection and external ear reconstruction is low. The occurrence of postoperative infection was not linked with smoking or the presence of diabetes, but strongly associated with a state of immunosuppression, which is why a perioperative antibiotic prophylaxis in immune-compromised patients may be considered.
