Abstract BACKGROUND Patients with chiasmatic-hypothalamic low grade glioma (CHLGG) have frequent MRIs with gadolinium based contrast agents (GBCA) for disease monitoring. Cumulative gadolinium deposition in children is a potential concern. The purpose of this research is to establish whether MRI with GBCA is necessary for determining tumor progression in children with CHLGG. METHODS Children with progressive CHLGG were identified from Texas Children’s Cancer Center between 2005–2019. Pre- and post-contrast MRI sequences were separately reviewed by one neuroradiologist who was blinded to the clinical course. Three dimensional measurements and tumor characteristics were collected. Radiographic progression was defined as a 25% increase in size (product of two largest dimensions) compared to baseline or best response after initiation of therapy. RESULTS A total of 28 patients with progressive CHLGG including 683 MRIs with GBCA (mean 24 MRIs/patient; range: 10–43 MRIs) were reviewed. No patients had a diagnosis of NF1. Progression was observed 92 times, 91 (98.9%) on noncontrast and 90 (97.8%) on contrast imaging. Sixty-seven radiographic and/or clinical progressions necessitating management changes were identified in all (100%) noncontrast sequences and 66 (98.5%) contrast sequences. Tumor growth >2 mm in any dimension was identified in 184/187(98.4%) on noncontrast and 181/187(96.8%) with contrast imaging. Non primary metastatic disease was seen in seven patients (25%), which were better visualized on contrast imaging in 4 (57%). CONCLUSION MRI without GBCA effectively identifies patients with progressive disease. One should consider eliminating contrast in imaging of children with CHLGG with GBCA reserved for monitoring those with metastatic disease.

415 Background: Immune checkpoint inhibitors (ICI) have been approved in solid tumors with dMMR. However, only limited data are available for PDAC with dMMR given the rarity of dMMR in PDAC. We evaluated efficacy of ICIs in PDAC with dMMR. Methods: Retrospective clinical and pathologic data were collected for patients (pts) with pancreatic adenocarcinoma from May 2017 to June 2020 at Moffitt cancer center. Results: We identified 10 pts with dMMR PDAC. The median age was 64.5 years (range: 42-86) and 4 pts were male. 4 pts had resectable disease, 3 had locally advanced and 3 had metastatic disease at initial diagnosis. MSH6 deficiency (def) was found in 2 cases, PMS2 def in 2, MLH/PMS2 def in 5, and MSH2/MSH6 in 1. 7 pts were treated with ICIs. 3 pts had locally advanced and 4 had metastatic disease when they started ICIs. 5 received Pembrolizumab (pem), 1 received ipilimumab/ nivolumab (ipi/nivo), and 1 received pem then ipi/nivo after progressive disease (PD) on pem. The median number of prior lines of chemotherapy was 1 (range 0-2). 6 pts were evaluable, and 1 had rapid disease progression after 1 dose of pem. Among 6 evaluable pts, 3 had an objective response (1: complete response and 2: partial response), and 2 had stable disease (SD). Median progression-free survival was 8.2 mo, and median overall survival was not reached with median follow-up (FU) of 6.8 mo. The median duration of response was not reached with a median FU of 22.6 mo. The pt with CR remained disease-free for up to 22 months. The pt whose treatment was switched to ipi/nivo after PD on pem achieved SD > 4mo on ipi/nivo. While on immunotherapy, one patient with ipi/nivo developed immunotherapy associated rash requiring systemic steroids, and another on pem developed hypothyroidism requiring levothyroxine. Conclusions: This series suggest ICIs can provide durable clinical efficacy in pts with dMMR PDAC.

Abstract BACKGROUND 80% of childhood cancer are located in low- and middle-income countries (LMIC). The most common form of presentation is disseminated or metastatic disease. The rate of survival has not been equitable across the world, since in these countries only 1 of 5 children are cured. OBJECTIVE To evaluate the clinical and histopathological features of patients with metastatic pediatric solid tumors, in a single referral cancer center in Honduras. METHODS We conducted a retrospective review of patients diagnosed with pediatric solid tumors from January 2010 to April 2020. Among the 260 patients through a collection form, we obtained: sociodemographic characteristics, clinical presentation at diagnosis, common histological subtypes, sites of metastasis, treatment and outcome at the time of follow-up. RESULTS During the last 10 years, 260 cases of childhood cancer were referred to our center for treatment. 127 patients (48.8%), have a solid tumor, patients ranged in age from 1 to 18 years and distribution for sex were 38% for males and 62% females. At the time of initial diagnosis 40/127 (31%) have advanced disease (stages III and IV). We found brain metastases in 22/40 cases (55%), the primary cancer was localized at CNS in 13/22 (59%) and the most common extracranial tumors causing brain metastases were neuroblastoma (4/22), rhabdomyosarcoma (3/22), retinoblastoma (2/22). Currently in the follow-up there were 18/22 (82%) died and 4/22 (18%) are in treatment with palliative intent. CONCLUSION There is a lack of information about the epidemiology of brain metastases among children with solid tumors in the low/middle income countries (LMIC) where the prognosis of metastatic disease is very poor, despite efforts, multimodal therapy and multidisciplinary management, in absence of other options like bone marrow transplantation, and reliable access to high-quality medicines. For our countries, timely diagnosis is still the main determining factor for cure.

e19645 Background: The natural history of isolated gonadal vein thrombosis (GVT) occurring in cancer patients (pts) is not well described in the medical literature. GVT in cancer pts it is of uncertain clinical significance. Methods: Utilizing a software program allowing a searchable database of radiology reports, the computerized tomographic scan (CT) reports of pts at a single cancer center from January 1, 2004 to June 30, 2011, were searched for the term “gonadal vein thrombus”. Pts included in this analysis had a diagnosis of cancer, isolated GVT (i.e. no evidence of thrombosis at another site), and at least six months of follow-up information. Results: 162 cancer pts with GVT were identified for analysis [median age 57.8 ± 12 years, right GVT 89 pts (54.9%), left GVT 59 pts (36.4%), bilateral 14 pts (8.6%)]; the majority of the pts (96, 59.3%) had a non-gynecologic malignancy. At the time of diagnosis of GVT the majority of pts were receiving chemotherapy (84, 51.9%); 70 pts (43.2%) had surgery within the prior six months (the most common being hysterectomy, 127 pts, 78.6%). The majority of pts in this study had metastatic disease (93, 57.4%) as well as active cancer (138, 85.1%, defined as GVT occurring at the time of cancer diagnosis, disease recurrence, metastatic disease, or treatment for cancer within the prior six months); median follow-up time was 22 months. A minority of pts received anticoagulation (28pts, 17.2%). Twenty-two pts (13.6%) developed a recurrent venous thromboembolic event (VTE); these events were pulmonary embolism (12 pts, 7.4%), deep venous thrombosis (5 pts, 3.1%), inferior vena cava thrombosis (4 pts, 2.5%). Median time to development of re-thrombosis was 7 months (range 2-13.5 months). Active cancer was the only risk factor significantly associated with recurrent VTE (p = 0.047); pts with prior hysterectomy had a significantly reduced risk of recurrent VTE (p = 0.036). Conclusions: Incidental isolated GVT identified in cancer pts has a high risk of recurrent VTE (13.6%). Based upon specific pts risk factors for VTE, treatment of an incidentally detected GVT in cancer pts with anticoagulation, as per guidelines for other VTE sites, may be indicated.

93 Background: Quality performance measures for cancer care, including use of chemotherapy in the last two-weeks of life, will be required for reporting. In this study, we evaluated the pattern and frequency of chemotherapy use for ST patients in the last two-weeks of life, and whether such treatment included standard or investigational drugs. Methods: We conducted a retrospective study of 5,607 adult cancer patients (≥18 years) who received their care at The University of Texas MD Anderson Cancer Center and died between December 01, 2010 through May 31, 2012. Data on patients’ demographics, and chemotherapy agents dispensed (excluded: hormones) were obtained from the institution’s administrative databases. Type of treatment (research versus standard) was obtained from our chemotherapy dispensed database. Chi-square test and Fisher's exact test were used to determine the association between categorical variables.All statistically significant levels were determined with p values < 0.05. Results: Only 3.9% (216/5,607) of ST patients who died had received chemotherapy within 14 days EOL. For those 216 patients who received chemothapy: median age 64 years; 48% female; 89% metastatic disease. The distribution by chemotherapy treatment route: intravenous (IV) 85%; IV plus oral 6%; oral 6%; other 3%. The distribution of patients by number of chemotherapy agents: one 56%; two 31%, and three or more 13%. Among those who received chemotherapy, 98.6% (213/216) of the chemotherapy administered were standard agents. There were no differences in frequency distribution for chemotherapy treatment route (p>0.05), number of chemotherapy agents (p>0.05) between patients with metastatic and non-metastatic disease, or between men and women (p>0.05). Conclusions: Our results indicate EOL chemotherapy use was infrequent in our patients with STs, and most of those treated received standard chemotherapy, with simple one or two drug regimens. We need more research to determine factors that influence chemotherapy use at EOL, and if it palliates physical symptoms and/or emotional distress in advanced stages of disease.

e16088 Background: ACC is a rare malignancy with limited data to guide management of metastatic disease. Prior research regarding survival has focused on pts with locoregional disease, but has not offered insight into the management and outcomes of pts with metastatic disease. Methods: We retrospectively reviewed patients (pts) with metastatic ACC who were treated with systemic therapy between January 2000 and October 2016 at The Ohio State University Comprehensive Cancer Center. Kaplan-Meier and Cox proportional hazards regression models were used for survival analysis. Results: A total of 18 pts received systemic therapy for distant metastatic disease. Median age at diagnosis was 51 (range 31 – 72). Median overall survival (OS) from time of diagnosis of ACC was 15.5 months (95% CI 4.8 – 28.2), and from time of systemic treatment (ST) was 7.1 months (95% CI 3.3 – 26). A germline variant of uncertain significance in MSH2 (c.138C > G) was identified in one patient. Baseline FDG-PET scans were obtained in 11/18 pts, and demonstrated avidity in all patients. Maximum SUV ranged from 4.1 to 47.6, with a median of 15. First line therapy was etoposide, doxorubicin, cisplatin, and mitotane (EDPM) in 13/18 pts and clinical trial with IMC-A12 (IGF-1 receptor antibody) in four pts. Median duration of first line therapy was 1.8 months (95% CI 0.9 – 2.8). Survival was not statistically different for patients receiving EDPM as first or second line therapy (median OS 23.3 vs 12.0 months, p = 0.96). Additional lines of therapy included EDPM, IMC-A12, AT-101, mifepristone, OSI-906 (IGF-1R inhibitor), and nivolumab. Median lines of therapy given were 2. The presence of bone metastases (p = 0.69) or lung metastases (p = 0.21) at the time of initiation of ST was not associated with OS from ST. Conclusions: In our experience, the prognosis of pts with metastatic ACC receiving systemic therapy is poor with most pts receiving ≤ 2 lines of therapy. Patients receiving first or second line EDPM seemed to have worse outcomes than noted in previously published trials, possibly due to our patients being sicker at baseline. Metastasis to the lung or bone at initiation of ST did not impact OS.

The Impact

Purpose The 2018 American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) guideline on HER2 testing in breast cancer permits reclassification of cases with HER2-equivocal results by FISH. The impact of such reclassification is unclear. We sought to determine the proportion of HER2-equivocal cases that are reclassified as HER2-negative and the impact of anti-HER2 therapy on survival in HER2-equivocal cases. Methods We reviewed medical records of breast cancer patients who had HER2 testing by fluorescence in stitu hybridization (FISH) and immunohistochemistry (IHC) performed or verified at The University of Texas MD Anderson Cancer Center during April 2014 through March 2018 and had equivocal results according to the 2013 ASCO/CAP guideline. The population was divided into 2 cohorts according to whether the biopsy specimen analyzed came from primary or from recurrent or metastatic disease. HER2 status was reclassified according to the 2018 ASCO/CAP guideline. Overall survival (OS) and event-free survival (EFS) were calculated using the Kaplan-Meier method, and the relationship between anti-HER2 therapy and clinical outcomes was assessed. Results We identified 139 cases with HER2-equivocal results according to the 2013 ASCO/CAP guideline: 90 cases of primary disease and 49 cases of recurrent/metastatic disease. Per the 2018 ASCO/CAP guideline, these cases were classified as follows: overall, HER2-negative 112 cases (80%), HER2-positive 1 (1%), and unknown 26 (19%); primary cohort, HER2-negative 85 (94%), HER2-positive 1 (1%), unknown 4 (4%); and recurrent/metastatic, HER2-negative 27 (55%) and unknown 22 (45%). Five patients in the primary-disease cohort and 1 patient in the recurrent/metastatic-disease cohort received anti-HER2 therapy. There was no significant association between anti-HER2 therapy and OS or EFS in either cohort (primary disease: OS, p = 0.67; EFS, p = 0.49; recurrent/metastatic-disease, OS, p = 0.61; EFS, p = 0.78. Conclusions The majority of HER2-equivocal breast cancer cases were reclassified as HER2-negative per the 2018 ASCO/CAP guideline. No association between anti-HER2 therapy and OS or EFS was observed. HER2-equivocal cases seem to have clinical behavior similar to that of HER2-negative breast cancers.
