1Q Gain

Purpose The goal of this study was to analyze the association of copy number gain of 1q in favorable-histology Wilms tumors (FHWTs) with event-free survival (EFS) and overall survival (OS) within each tumor stage and with 1p and 16q copy number loss and/or loss of heterozygosity. Methods Unilateral FHWTs from 1,114 patients enrolled in National Wilms Tumor Study-5 that were informative for 1p and 16q microsatellite markers (previously determined) and informative for 1q gain, 1p loss, and 16q loss using multiplex ligation-dependent probe amplification were analyzed. Results Eight-year EFS was 86% (95% CI, 84% to 88%) for the entire cohort. Of 1,114 patients, 317 tumors (28%) displayed 1q gain. Eight-year EFS was 77% for those with 1q gain and 90% for those lacking 1q gain (P < .001). Eight-year OS was 88% for those with 1q gain and 96% for those lacking 1q gain (P < .001). Within each disease stage, 1q gain was associated with inferior EFS (stage I, 85% v 95%; P = .0052; stage II, 81% v 87%; P = .0775; stage III, 79% v 89%; P = .01; stage IV, 64% v 91%; P = .001). OS was significantly inferior in patients with stage I (P < .0015) and stage IV disease (P = .011). With multivariable analysis, 1q gain was associated with an increased relative risk of relapse of 2.4 (P < .001), whereas 1p loss was not, despite significance on univariable analysis. Conclusion Gain of 1q is associated with inferior survival in unilateral FHWTs and may be used to guide risk stratification in future studies.

1Q Gain

10014 Background: Wilms tumor is the most common childhood renal tumor. While the majority of patients with favorable histology Wilms Tumor (FHWT) have good outcomes, many patients still experience recurrence and death from disease. This study’s goal was to determine if chromosome 1q gain is associated with event-free (EFS) and overall survival (OS) in FHWT. Methods: Unilateral FHWT samples were obtained from patients enrolled on National Wilms Tumor Study-4 and Pediatric Oncology Group 9046, “A Molecular Genetic analysis of Wilms Tumor.” 1q gain, 1p loss, and 16q loss were determined using multiplex ligation-dependent probe amplification (MLPA). Results: The eight-year EFS was 87% (95% CI 82%, 91%) for the entire cohort of 212 patients. Tumors of 58/212 patients (27%) displayed 1q gain. A strong relationship between 1q gain and 1p/16q loss was observed. The eight-year EFS was 76% (95% CI 63%, 85%) for those with 1q gain and 93% (95% CI 87%, 96%) for those lacking 1q gain (p=0.0024). The eight-year OS was 89% (95% CI 78%, 95%) for those with 1q gain, and 98% (95% CI 94%, 99%) for those lacking 1q gain (p=0.0075). Gain of 1q did not correlate with disease stage (p=0.16). After stratification for stage, 1q gain was associated with a significant increase in the risk of failure (risk ratio estimate: 2.72, p=0.0089). Conclusions: Gain of 1q is associated with inferior EFS and OS in FHWT and may provide a new and valuable prognostic marker to stratify therapy for patients with FHWT. A confirmatory study is necessary before this biomarker is incorporated into risk stratification schema of future therapeutic studies.

1Q Gain

Purpose Wilms tumor (WT) is the most common pediatric renal tumor. Treatment planning under International Society of Paediatric Oncology (SIOP) protocols is based on staging and histologic assessment of response to preoperative chemotherapy. Despite high overall survival (OS), many relapses occur in patients without specific risk factors, and many successfully treated patients are exposed to treatments with significant risks of late effects. To investigate whether molecular biomarkers could improve risk stratification, we assessed 1q status and other potential copy number biomarkers in a large WT series. Materials and Methods WT nephrectomy samples from 586 SIOP WT 2001 patients were analyzed using a multiplex ligation-dependent probe amplification (MLPA) assay that measured the copy number of 1q and other regions of interest. Results One hundred sixty-seven (28%) of 586 WTs had 1q gain. Five-year event-free survival (EFS) was 75.0% in patients with 1q gain (95% CI, 68.5% to 82.0%) and 88.2% in patients without gain (95% CI, 85.0% to 91.4%). OS was 88.4% with gain (95% CI, 83.5% to 93.6%) and 94.4% without gain (95% CI, 92.1% to 96.7%). In univariable analysis, 1q gain was associated with poorer EFS (P < .001; hazard ratio, 2.33) and OS (P = .01; hazard ratio, 2.16). The association of 1q gain with poorer EFS retained significance in multivariable analysis adjusted for 1p and 16q loss, sex, stage, age, and histologic risk group. Gain of 1q remained associated with poorer EFS in tumor subsets limited to either intermediate-risk localized disease or nonanaplastic localized disease. Other notable aberrations associated with poorer EFS included MYCN gain and TP53 loss. Conclusion Gain of 1q is a potentially valuable prognostic biomarker in WT, in addition to histologic response to preoperative chemotherapy and tumor stage.

Purpose To determine if tumor-specific loss of heterozygosity (LOH) for chromosomes 1p or 16q is associated with a poorer prognosis for children with favorable-histology (FH) Wilms tumor entered on the fifth National Wilms Tumor Study (NWTS-5). Patients and Methods Between August 1995 and June 2002, 2,021 previously untreated children with FH or anaplastic Wilms tumor, clear-cell sarcoma of the kidney (CCSK) or malignant rhabdoid tumor of the kidney (RTK), were treated with stage- and histology-specific therapy. Their tumors were assayed for LOH for polymorphic DNA markers on chromosomes 1p and 16q. Results LOH for 1p or 16q was rarely observed in CCSK (n = 90) or RTK (n = 22). The relative risk (RR) of relapse for patients with FH stage I to IV tumors with LOH, stratified by stage, was 1.56 for LOH 1p (P = .01) and 1.49 for LOH 16q (P = .01), whereas the RR of death was 1.84 (P = .03) and 1.44 (P = .15), respectively. When the effects of LOH for both regions were considered jointly among patients with stage I to II FH disease, the risks of relapse and death were increased for LOH 1p only (RR = 2.2, P = .02 for relapse; RR = 4.0, P = .02 for death), for LOH 16q only (RR = 1.9, P = .01 and RR = 1.4, P = .60) and for LOH for both regions (RR = 2.9, P = .001 and RR = 4.3, P = .01) in comparison with patients with LOH at neither locus. The risks of relapse and death for patients with stage III to IV FH tumors were increased only with LOH for both regions (RR = 2.4, P = .01 and RR = 2.7, P = .04). Conclusion Tumor-specific LOH for both chromosomes 1p and 16q identifies a subset of FH Wilms tumor patients who have a significantly increased risk of relapse and death. LOH for these chromosomal regions can now be used as an independent prognostic factor together with disease stage to target intensity of treatment to risk of treatment failure.

ObjectiveTo evaluate overall survival (OS) and progression-free survival (PFS) after adjuvant therapy in stage I to stage IV uterine carcinosarcoma with rhabdomyosarcoma differentiation.MethodsMemorial Sloan-Kettering Cancer Center medical records from 1990 to 2012 were reviewed. Patients who received chemotherapy with or without radiation therapy (RT), or RT alone, for completely resected stage I to stage IV uterine carcinosarcoma with rhabdomyosarcoma differentiation were included.ResultsOf 53 patients, International Federation of Gynecology and Obstetrics stage distribution was as follows: I, 13 (24.5%); II, 8 (15.1%); III, 13 (24.5%); and IV, 19 (35.9%). Forty-one (77.4%) of 53 patients received adjuvant chemotherapy, and 34% of the patients who received chemotherapy also received pelvic RT or intravaginal brachytherapy (IVRT). Twelve (22.6%) of the 53 patients received only pelvic RT with/without IVRT. Paclitaxel-carboplatin was the most commonly used adjuvant chemotherapy treatment. The median PFS for the entire cohort was 13.4 months (95% confidence interval [CI], 10.5–17.0). The median OS for the entire cohort was 23.0 months (95% CI, 16.9–34.3). The median PFS periods by stage were 15.9 months for stages I/II versus 11.2 months for stages III/IV (P= 0.012). Median OS was not reached in the early-stage cohort. The median OS for the late-stage cohort was 20.9 months (P= 0.004). The median PFS periods by treatment were 10.4 months for pelvic RT with/without IVRT group versus 13.1 months for chemotherapy with/without pelvic RT with/without IVRT group (P= 0.498). The median OS periods by treatment were 23.6 months for chemotherapy with/without pelvic RT with/without IVRT group versus 16.9 months for pelvic RT with/without IVRT group (P= 0.501).ConclusionThe results suggest that chemotherapy alone or in combination with RT is associated with longer PFS and OS compared to RT alone. Only the stage of disease significantly affected PFS and OS.

ObjectiveWe sought to describe a large, international cohort of patients diagnosed with primary mucinous ovarian carcinoma (PMOC) across 3 tertiary medical centers to evaluate differences in patient characteristics, surgical/adjuvant treatment strategies, and oncologic outcomes.MethodsThis was a retrospective review spanning 1976–2014. All tumors were centrally reviewed by an expert gynecologic pathologist. Each center used a combination of clinical and histologic criteria to confirm a PMOC diagnosis. Data were abstracted from medical records, and a deidentified dataset was compiled and processed at a single institution. Appropriate statistical tests were performed.ResultsTwo hundred twenty-two patients with PMOC were identified; all had undergone primary surgery. Disease stage distribution was as follows: stage I, 163 patients (74%); stage II, 8 (4%); stage III, 40 (18%); and stage IV, 10 (5%). Ninety-nine (45%) of 219 patients underwent lymphadenectomy; 41 (19%) of 215 underwent fertility-preserving surgery. Of the 145 patients (65%) with available treatment data, 68 (47%) had received chemotherapy—55 (81%) a gynecologic regimen and 13 (19%) a gastrointestinal regimen. The 5-year progression-free survival (PFS) rates were 80% (95% confidence interval [CI], 73%–85%) for patients with stage I to II disease and 17% (95% CI, 8%–29%) for those with stage III to IV disease. The 5-year PFS rate was 73% (95% CI, 50%–86%) for patients who underwent fertility-preserving surgery.ConclusionsMost patients (74%) presented with stage I disease. Nearly 50% were treated with adjuvant chemotherapy using various regimens across institutions. The PFS outcomes were favorable for those with early-stage disease and lower but acceptable for those who underwent fertility preservation.

e18719 Background: Clinical pathways have been introduced as tools to optimize cancer care delivery, but evidence of their value in the real world is limited. This retrospective study was performed to assess treatment patterns and clinical outcomes in patients with non-small cell lung cancer (NSCLC) before and after pathway implementation at Tennessee Oncology (TO). Methods: Chart data were abstracted for patients (≥18 years) diagnosed with Stage I-IV NSCLC who initiated first-line (1L) systemic treatment at a TO clinic and had follow-up for ³6 months or until death. Patients were divided into two cohorts: pre-pathways (treatment initiation 2014–2015) and post-pathways (treatment initiation 2016–2018). Patient characteristics, treatment patterns, and outcomes were described and compared across cohorts. An exploratory study endpoint was the evaluation of outcomes based on disease stage at diagnosis. Results: Among 501 patients (251 pre-pathways and 250 post-pathways), most had advanced or metastatic NSCLC at diagnosis (Stage III: 40%; Stage IV: 42%). Chemotherapy comprised almost all 1L systemic therapy used pre-pathways (Stage I/II: 100%; Stage III: 96%; Stage IV: 83%). Post-pathways, chemotherapy remained the most common 1L therapy in patients with Stage I/II (89%) and Stage III (72%) disease, but among patients with Stage IV disease, use of chemotherapy decreased (47%) and immuno-oncology (IO) therapy alone or in combination became common (45%). Median duration of 1L therapy was longer post-pathways in patients with Stage III (2.1 months vs 1.4 months pre-pathways; P < 0.01) and Stage IV disease (3.3 months vs 2.3 months pre-pathways; P < 0.01) but did not differ among Stage I/II patients. Median progression-free survival was significantly longer post-pathways in patients with Stage IV disease (7.0 months vs 4.2 months pre-pathways; P < 0.05), but not in other disease-stage subgroups. Median overall survival increased non-significantly post-pathways for all disease stage subgroups (Stage I/II: 26 months vs 20 months pre-pathways; Stage III: 26 months vs 20 months; Stage IV: 10 months vs 9 months). For each disease stage, rates of severe adverse events were similar between cohorts. Conclusions: While outcomes for patients diagnosed with Stage III/IV NSCLC were generally improved following the implementation of clinical pathways, this change coincided with a dramatic shift in available treatment options. Improvements post-pathways were mainly observed in patients diagnosed with advanced disease. Thus, differences in outcomes between pre-pathways and post-pathways cohorts in our study are more likely attributable to other evolving practices in cancer care, particularly the availability of newer, more effective treatments such as IO therapy as part of standard practice, than implementation of the clinical pathways.

PURPOSE: Previous studies demonstrated that chemotherapy with either cisplatin, vincristine, and fluorouracil (regimen A) or cisplatin and continuous infusion doxorubicin (regimen B) improved survival in children with hepatoblastoma. The current trial is a randomized comparison of these two regimens. PATIENTS AND METHODS: Patients (N = 182) were enrolled onto study between August 1989 and December 1992. After initial surgery, patients with stage I–unfavorable histology (UH; n = 43), stage II (n = 7), stage III (n = 83), and stage IV (n = 40) hepatoblastoma were randomized to receive regimen A (n = 92) or regimen B (n = 81). Patients with stage I–favorable histology (FH; n = 9) were treated with four cycles of doxorubicin alone. RESULTS: There were no events among patients with stage I-FH disease. Five-year event-free survival (EFS) estimates were 57% (SD = 5%) and 69% (SD = 5%) for patients on regimens A and B, respectively (P = .09) with a relative risk of 1.54 (95% confidence interval, 0.93 to 2.5) for regimen A versus B. Toxicities were more frequent on regimen B. Patients with stage I-UH, stage II, stage III, or stage IV disease had 5-year EFS estimates of 91% (SD = 4%), 100%, 64% (SD = 5%), and 25% (SD = 7%), respectively. Outcome was similar for either regimen within disease stages. At postinduction surgery I, patients with stage III or IV disease who were found to be tumor-free had no events; those who had complete resections achieved a 5-year EFS of 83% (SD = 6%); other patients with stage III or IV disease had worse outcome. CONCLUSION: Treatment outcome was not significantly different between regimen A and regimen B. Excellent outcome was achieved for patients with stage I-UH and stage II hepatoblastoma and for subsets of patients with stage III disease. New treatment strategies are needed for the majority of patients with advanced-stage hepatoblastoma.

Abstract BACKGROUND Traditionally, neuroangiography for diagnosis and therapy has been achieved via the transfemoral route. Femoral access, however, has been associated with catastrophic complications. Although transradial access (TRA) has been adopted late by the field of neuroendovascular surgery, several groups have recently demonstrated a dramatically safe and rapid learning curve with a radial-first approach. However, there is a need for a detailed illustrative approach on the transradial technique. OBJECTIVE To provide a detailed description of the operative technique with step-by-step illustrations derived from our single center series of 506 cases, as an early adopter. METHODS A step-by-step illustrated approach to our technique of transradial angiography is provided, based on our clinical experience of an early radial-first approach. Prospective review of patients undergoing transradial angiography and interventions from April 1 to November 30, 2019, at our institution was performed. We included all cases that received radial-first arterial access for diagnostic and interventional neuroangiography. Efficacy, complications, catheter use, and radiation metrics of TRA for the entire cohort were noted. The radial approach was described in 4 stages beginning from the wrist (Stage I) and ending with distal access to target vessel of interest (Stage IV). RESULTS A total of 506 patients underwent TRA over the 7-mo period. Procedural success was achieved in 92.3% of patients (93.7% for diagnostic and 88.5% for interventional). Crossover to the femoral route occurred in 33 (6.5%) cases (25 diagnostic and 8 interventional). The majority occurred in Stage I. No major complications were noted. CONCLUSION Our preferred technique for the transradial approach provides excellent safety and efficacy in performing diagnostic and interventional neuroangiography. The illustrated technical steps are expected to provide guidance for early adopters of TRA.
