Abstract INTRODUCTION Low grade glioma (LGG) is the most common central nervous system (CNS) tumor in children accounted for 30–50%. Regarding benign characteristic of disease, surgical management remains the mainstay of treatment. However, surgical approach is limited in some conditions such as location at brainstem or infiltrative tumor. Chemotherapy and radiation treatments have been included in order to control tumor progression. The 5-years survival rate is approach 90% especially in patients who receive complete resection. However, the outcome of children with LGG in low to middle income is limited. Therefore, the aim of the study was to determine long-term outcome of children with newly diagnosed LGG. METHODS A retrospective study enrolled children aged <18 years who were newly diagnosed LGG during January 2006- December 2019. Diagnosis of LGG was confirmed by histological findings of grade I and II according to WHO criteria. RESULTS A total of 40 patients, female to male ratio was 1:1.35 and mean (SD) for age was 6.7 (4.0) years. The most common location was optic chiasmatic pathway (42.5%), followed by suprasellar region (25.0%). Sixty percent of patients received at least partial tumor removal. Chemotherapy and radiation had been used in 70% and 10.0% respectively. The 10-year progression free survival was 74.1±11.4% and overall survival was 96.2±3.8%. SUMMARY: Treatment of Pediatric LGG mainly required surgical management, however, chemotherapy and radiation had been used in progressive disease. The outcome was excellent.

✓ The feasibility of radical surgery for astrocytomas of the optic chiasm/hypothalamus has been reported by several groups. Such surgery carries significant risks, however, including permanent damage to the pituitary gland, optic apparatus, hypothalamic structures, and carotid arteries. The benefits of radical surgery, both in terms of efficacy and toxicity, should, therefore, be evaluated against standard therapy, as is usually done for new chemotherapeutic protocols. To this end, a retrospective review was performed of 33 patients treated at Children's Hospital of Philadelphia between 1976 and 1991 who met criteria that would have made them eligible for radical surgery in many centers today, but were treated with either no surgery or conservative surgery (< 50% resection) or biopsy followed by adjuvant therapy with local radiation therapy (29 patients) and/or chemotherapy with actinomycin-D and vincristine (18 patients). The review encompassed all children with a globular enhancing mass of at least 2 cm in the hypothalamic/chiasmatic region, no evidence of optic nerve involvement or involvement of the optic radiations by computerized tomography or magnetic resonance imaging, and follow up of at least 3 years. All but one patient had tissue confirmation of a low-grade or pilocytic astrocytoma. Thirteen of the patients were 2 years of age or younger at diagnosis. Five individuals died: three of tumor progression, one of acute shunt malfunction, and one of intercurrent infection. The remaining 28 were alive at last follow up, a mean of 10.9 years from diagnosis. Twenty-three surviving patients have functional vision in at least one eye, 12 require no endocrine replacement, and 16 are in or have completed schooling with regular academic requirements. If radical surgery is to become standard care for children with low-grade astrocytomas of the hypothalamic/chiasmatic region, long-term survival and functional outcome will have to equal or surpass those of historical controls who were treated conservatively.

Surgical Field

Radical resection of low-grade gliomas can decrease the incidence of recurrence, the time to tumor progression, and the incidence of malignant transformation. The authors present a series of 25 patients who underwent craniotomy and resection of low-grade tumor in an intraoperative magnetic resonance (MR) imager. This is an open configuration 0.5-tesla imager developed by The Brigham and Women's Hospital and General Electric, in which a patient can be placed to undergo surgery. Gross-total removal was accomplished under real-time image guidance. These intraoperative images allow definitive localization and targeting of the lesions and accommodate anatomical changes that may occur during surgery. The authors consistently found that the extent of abnormality seen on the intraoperatively obtained films of resection was larger than that apparent in the surgical field of view alone. Intraoperative imaging made accurate surgical identification of these abnormal areas and subsequent resection possible. Patients with tumors adjacent to or within motor or language cortex underwent resection while awake, with monitoring of neurological function. In these cases, an aggressive resection without increased neurological morbidity was accomplished using the image guidance in conjunction with serial testing. A 1-month postoperative MR image was obtained in all patients. These correlated with the final intraoperative images obtained after the resection was completed. Only one patient had a mild postoperative deficit that remained at the 1-month follow-up examination. As the long-term outcome in patients with low-grade gliomas has been shown to correspond to the degree of resection, surgical resection in which intraoperative MR imaging guidance is used can be an invaluable modality in the treatment of these tumors.

Background MZL is a low-grade non-Hodgkin's lymphoma (NHL) which involves lymph nodes, extranodal sites, or spleen. It is sensitive to radiation therapy, which is used in localized disease with curative intent. Yttrium-90 ibritumomab tiuxetan [(90)Y-IT; Zevalin] is a radio-immunoconjugate (RIC) that targets CD20. It is approved for relapsed/refractory low grade and follicular NHL. The data on its use in MZL is limited. We present long-term outcome of the largest reported cohort of MZL patients who received (90)Y-IT. Methods Medical records of patients who received treatment with (90)Y-IT at Mayo Clinic Cancer Center between January 2004 and December 2018 were analyzed. We selected patients with MZL and reviewed clinical data including age, gender, MZL type, clinical stage (Ann Arbor Staging System), treatment response, (90)Y-IT related adverse effects (AEs), as well as lymphoma and treatment related events. All patients received (90)Y-IT according to the standard treatment guidelines. Overall response rate (ORR) and complete response rate (CR) were calculated. Progression-free survival (PFS), time to next therapy (TTNT), and overall survival (OS) were analyzed using the Kaplan-Meier method. Results Twenty-one patients were identified (Table 1). The median age at diagnosis was 60 years (range, 11-81) and 71% (15/21) were female. 52% (11/21) were previously-untreated (UMZL) while 48% (10/21) were relapsed (RMZL). The median number of pretreatments in RMZL patients was 2 (range, 1-3). ECOG performance status at the time of treatment was 0 in 90% (19/21) and 1 in 10% (2/21). 62% (13/21) were stage III/IV disease at the time of (90)Y-IT therapy. The median follow-up was 8.5 years (95% CI; 4.5, 12.4); 17 (81%) patients remain alive. The ORR was 91% (19/21) with the two non-responders being in the RMZL group. The CR rate was 81% (17/21) and 65% (11/17) remain in CR at a median follow-up of 5.7 years (95% CI; 1.4, 11). Nine (43%) patients had a relapse during the study period. More relapses occurred in the RMZL group (7/10; 70%) compared to (2/11; 18%) in the UMZL group. Median PFS (whole cohort) was 10 years (95% CI; 2.1, NR) and TTNT (whole cohort) was not reached (NR) (95% CI; 2.1 years, NR). Median PFS was significantly higher in UMZL group compared to RMZL group NR (95% CI; 2.5 years, NR) vs 2.1 years (95% CI; 0.17, 9.9), respectively (Figure 1-A).Median OS (whole cohort) was 19.3 years (95% CI; 8.9, 19.3) without statistical difference in between UMZL group and RMZL group NR (95% CI; NR, NR) vs 16.6 years (95% CI; 9, 19.4), respectively (Figure 1-B). None of the 11 UMZL patients died at median follow up of 4.7 years (95% CI; 1.6, 9.2). All 4 deaths were in the RMZL group with 3 dying of transformation to high-grade lymphoma at 8, 22, and 25 months post-(90)Y-IT treatment. One patient died of myelodysplastic syndrome 7.3 years post-(90)Y-IT treatment while in CR. Toxicities were primarily hematologic. Grade ³3 neutropenia was observed in 6/21 (29%) patients with median time to nadir of 48.5 days (range, 19-70) and median time to recovery to normal absolute neutrophil count of 39.5 days (range, 7-476). Grade ³3 thrombocytopenia was observed in 3 (14%) patients with median time to nadir of 35 days (range, 19-357) and median time to recovery of 21 days (range, 2-538). Grade ³3 anemia was observed in only one patient. Only two patients required transfusions and growth factor support. Non-hematologic AEs included mild to severe fatigue in 4 patients. Conclusion RIC with (90)Y-IT is efficacious and well-tolerated in patients with previously untreated as well as relapsed MZL. As expected it appears to be more efficacious in previously untreated patients. Long-term complete remission (&gt;5 years) was observed in 52% of the study population (43% of UMZL and 9% of RMZL). Combination of efficacy, tolerability, and treatment schedule most convenient for patients makes (90)Y-IT a reasonable alternative to systemic therapy with immunotherapy, chemotherapy, or chemo-immunotherapy in management of MZL.

8123 Background: The high-dose sequential (HDS) chemotherapy approach, including early dose-intensification and autograft with peripheral blood progenitor cells (PBPC), was introduced several years ago (Gianni & Bonadonna, 1989); subsequently, it has been broadly used in the management of both non-Hodgkin s (NHL) and Hodgkin s Lymphoma (HL). The outcome of a large series of lymphoma patients treated with the HDS approach at 10 GITIL Centers is reported. Methods: Data have been collected on 1,266 patients, who received either the original or slightly modified HDS regimens. There were 213 HL and 1,053 NHL (630 intermediate/high-grade, 423 low-grade); median age was 46 yrs. Overall, 671 (53%) patients had refractory/relapsed disease, 595 (47%) were at diagnosis. Most patients were autografted with PBPC; 158 (12%) patients did not undergo autografting due to toxicity, disease progression or poor harvests. Results: Overall, 1,013 (80%) patients reached Complete Remission (CR) following HDS. As to December 2006, 93 (7%) patients died for early/late toxicities, 328 (26%) died for lymphoma, 844 are known to be alive. At a lead follow-up of 18 years, and a median follow-up of 5 yrs, the 5-yr Overall Survival (OS) projection is 64% (S.E.: 2%). The long-term survival was quite favorable in patients achieving a Complete Remission (CR), with a 5-yr OS projection of 76%. The prolonged OS in patients achieving CR was consistent in all lymphoma subtypes, i.e. both low and high-grade NHL (5-yr OS: 77% in both), and HL (5-yr OS: 72%). Patients at diagnosis had a significantly better outcome compared to patients treated for relapsed/refractory disease, again CR achievement was associated with prolonged survival in both subgroups (82% and 69%, respectively, at 5 yrs.). On multivariate Cox survival analysis, CR achievement was the most powerful predictor of long-term survival (HR 0.13, c.i.: 0.10–0.17). Lastly, achieving substantial tumor reduction before autografting had a major influence on the clinical outcome. Conclusions: 1. the HDS program is feasible in a multicenter setting; 2. the long-term outcome is well influenced by the CR status after HDS; 3. the influence of CR achievement on the long-term survival holds true in all lymphoma subtypes, including indolent lymphomas; 4. an adequate pre-autograft tumor debulking may contribute to a favorable long-term outcome.
