Abstract PURPOSE/OBJECTIVES Brain stem gliomas are up to 20% of all brain tumor in children and unusual in adults. Radiotherapy is mainstay of treatment. Surgery for brain stem glioma is difficult because of anatomical location. This study was performed to evaluate the clinical outcomes of radiotherapy in brain stem glioma. METHODS Retrospective analysis of brain stem glioma patients treated with radiation therapy (54Gy/30 fractions of IMRT/ 3D CRT) with or without surgery or chemotherapy or other agents. RESULTS Twenty-four patients (median age 11.8 years) were treated between 2016 and 2020. Male to female ratio was 2:3. Surgical approach (biopsy and partial removal) was done in 16 patients. Histology revealed that anaplastic ependymoma in 2 patients, low grade astrocytoma in 2 patients, anaplastic astrocytoma in 8 patients, glioblastoma in 4 patients and remaining 8 patients had no histologic diagnosis. Radiotherapy (dose- 54Gy/ 30 fractions) was given with the technique of IMRT or 3D CRT. At the time of follow up, 8 patients had local recurrence, 10 patients died of due to disease and recurrence, 14 patients were alive. Among alive patients, 2 patients were treated with chemotherapy and 12 patients with temozolomide for 12 cycles. Patients who received temozolomide got improvement in performance status and reduced clinical symptoms; among them, 6 patients had more than 50% objective tumor response in radiological findings for follow-up 3-6 months after radiotherapy. The 2-years overall survival (OS) rate was 58.3% and 2-years Event-free Survival (EFS) rate was 50%. The median survival time was 14 months. There is no grade 3 or greater acute and late toxicities. CONCLUSION As the LMIC country with limited resources, our results of radiotherapy followed by temozolomide in brain stem glioma have optimal outcomes. However, prospective studies of this select group of patients with larger number and longer follow up is required.

✓ Six children with a history of isolated facial nerve dysfunction or dizziness and nausea were treated for brain-stem glioma between 1984 and 1992. Computerized tomography and/or magnetic resonance (MR) imaging showed a focal, uniformly enhancing mass involving the facial nerve nucleus of the pons. All patients underwent biopsy; the histological diagnosis was juvenile pilocytic astrocytoma in five cases. In the remaining case the biopsy was nondiagnostic, although the surgeon believed that the lesion was a glioma. Postoperatively, five patients underwent conventional focal megavoltage radiation therapy (180 to 200 cGy/day) over a period of 5½ weeks to a total dose of approximately 5400 cGy. One child's family refused radiation therapy; she remained well and stable for 4 years, despite persistent facial weakness, and was eventually lost to follow-up review. Four irradiation-treated patients had complete resolution of their tumors on MR images and have had no evidence of neuropsychological or neuroendocrinological deficits during 4½ to 8 years of follow-up evaluation. Patients whose neuroradiological studies show a lesion resembling those in this series should undergo biopsy and, if the histology of a low-grade tumor (in particular, a juvenile pilocytic astrocytoma) is confirmed, should then receive focal radiation therapy with conventional megavoltage dosages.

✓ Between 1974 and 1985, 89 patients suffering from histologically confirmed, nonresectable low-grade astrocytomas located in the brain stem were entered into a retrospective study. Iodine-125 (125I) was implanted in 29 patients and iridium-192 (192Ir) in 26 patients. Computerized tomography revealed that 78% of the tumors in these patients were located chiefly in the mesencephalic region, 70% were circumscribed, and 78% were contrast-enhanced. Thirty-four patients underwent biopsy without prior aggressive tumor-specific therapy such as chemotherapy or external beam irradiation. Among these, 70% of the tumors were located predominantly in the pons, 74% were diffuse, and 59% were hypodense or isodense after contrast enhancement. Long-term follow-up investigations indicated that life expectancy after interstitial radiation therapy with 125I implanted directly by catheter either permanently or temporarily showed a more favorable trend than that after treatment with 192Ir. Interstitial radiation therapy with 125I appears to be an effective treatment for slowly proliferating, differentiated, well-delineated, nonresectable brain-stem gliomas. This technique makes it possible to achieve radio-surgical tumor control and, when carefully applied, represents the least traumatic treatment. Reduction of the tumor mass brings about improvement of the clinical symptoms. Further investigations on the biological behavior of brain-stem gliomas and prospective randomized long-term follow-up studies are necessary to evaluate the different kinds of treatment available for these patients.

Background:Obesity population are rising rapidly and have become a major health issue. Studies have shown that obesity is a low-grade inflammatory status characterized by increase in proinflammatory cytokines.Objectives:To examine the impact of overweight or obesity on disease activity and treatment responses to biologics in patients with ankylosing spondylitis (AS) in a real-world setting.Methods:Body mass index (BMI) is available in 1013 patients from the Chinese Ankylosing Spondylitis Imaging Cohort (CASPIC). Differences in clinical outcomes (such as BASDAI, ASDAS, BASFI, and ASAS HI) and treatment responses to biologics (ΔBASDAI and ΔASDAS) over 3, 6, 9, and 12 months are assessed between BMI categories (normal weight BMI <24 kg/m2; overweight BMI=24-28 kg/m2; obesity BMI ≥28 kg/m2) using Kruskal-Wallis test. The association between BMI and clinical characteristics and treatment responses to biologics was determined, and multivariate median regression analyses were conducted to adjust for confounders (such as age, gender, smoke, and HLA-B27).Results:Among 1013 patients with AS, overweight accounts for 33%, while obesity for 12.4%. There were significant differences between patients who were obese or overweight and those with a normal weight regarding clinical outcomes (BASDAI: 2.90/2.56 vs 2.21; ASDAS-CRP: 2.20/1.99 vs 1.81; BASFI: 2.13/1.69 vs 1.38; ASAS HI: 6.87/5.29 vs 5.12 and BASMI: 2.35/1.76 vs 1.62; all P<0.05). After adjusting for age, gender, smoke, and HLA-B27, obesity remained associated with higher disease activity (BASDAI: β=0.55, P=0.005; ASDAS-CRP: β=0.40, P<0.001), poorer functional capacity (BASFI: β=0.58, P=0.001), worse health index (ASAS HI: β=1.92, P<0.001) and metrology index (BASMI: β=0.71, P=0.013). For TNFi users, BMI was found to be negatively correlated with changes in disease activity (ΔBASDAI and ΔASDAS) in the multivariate regression model (all P<0.05), and overweight and obese patients showed an unsatisfactory reduction in disease activity during 3-month, 6-month, 9-month, and 12-month follow-up period, compared to normal weight patients (all P<0.05).Conclusion:Overweight or obesity impacts greatly on clinical outcomes and treatment responses to biologics in patients with ankylosing spondylitis, which argues strongly for obesity management to become central to prevention and treatment strategies in patients with AS.References:[1]Maachi M, Pieroni L, Bruckert E, et al.

Context.—Urothelial tumors are rare in young patients. Because of their rarity, the natural history of the disease in young patients remains poorly understood. Objective.—To understand the pathologic and clinical features of urothelial tumors of the urinary bladder in young patients. Design.—We identified 59 young patients with urothelial tumors of the urinary bladder treated at our institution and analyzed the tumors' pathologic features and the patients' clinical outcomes. Results.—All patients were 30 years or younger, with a mean age of 23.5 years (range, 4–30). Thirty-eight patients (64%) were male, and 21 (36%) were female. Most tumors were noninvasive, papillary urothelial tumors (49 of 59; 83%), including papillary urothelial neoplasms of low malignant potential (7 of 49; 14%), low-grade papillary urothelial carcinomas (38 of 49; 78%), and high-grade papillary urothelial carcinomas (4 of 49; 8%). Only a few (n = 10) of the urothelial tumors were invasive, invading the lamina propria (n = 5; 50%), muscularis propria (n = 4; 40%), or perivesical soft tissue (n = 1; 10%). Clinical follow-up information was available for 41 patients (69%), with a mean follow-up time of 77 months. Of 31 patients with noninvasive papillary urothelial tumors, only 1 patient (3%) later developed an invasive urothelial carcinoma and died of the disease, and 30 of these patients (97%) were alive at the end of follow-up, although 10 (32%) had local tumor recurrences. In the 10 patients with invasive urothelial carcinomas, 3 patients (30%) died of the disease and 5 others (50%) were alive with metastases (the other 2 [20%] were alive with no recurrence). Conclusion.—Urothelial tumors in young patients are mostly noninvasive, papillary carcinomas and have an excellent prognosis; however, a small subset of patients may present with high-grade invasive urothelial carcinomas that result in poor clinical outcomes.

Summary Barrett’s esophagus (BE) is the main pathological precursor of esophageal adenocarcinoma (EAC). Progression to high-grade dysplasia (HGD) or EAC from nondysplastic BE (NDBE), low-grade dysplasia (LGD) and indefinite for dysplasia (IND) varies widely between population-based studies and specialized centers for many reasons, principally the rigor of the biopsy protocol and the accuracy of pathologic definition. In the Republic of Ireland, a multicenter prospective registry and bioresource (RIBBON) was established in 2011 involving six academic medical centers, and this paper represents the first report from this network. A detailed clinical, endoscopic and pathologic database registered 3,557 patients. BE was defined strictly by both endoscopic evidence of Barrett’s epithelium and the presence of specialized intestinal metaplasia (SIM). A prospective web-based database was used to gather information with initial and follow-up data abstracted by a data manager at each site. A total of 2,244 patients, 1,925 with no dysplasia, were included with complete follow-up. The median age at diagnosis was 60.5 with a 2.1:1 male to female ratio and a median follow-up time of 2.7 years (IQR 1.19–4.04), and 6609.25 person years. In this time period, 125 (5.57%) progressed to HGD/EAC, with 74 (3.3%) after 1 year of follow-up and 38 (1.69%) developed EAC, with 20 (0.89%) beyond 1 year. The overall incidence of HGD/EAC was 1.89% per year; 1.16% if the first year is excluded. The risk of progression to EAC alone overall was 0.57% per year, 0.31% excluding the first year, and 0.21% in the 1,925 patients who had SIM alone at diagnosis. Low-grade dysplasia (LGD) progressed to HGD/EAC in 31% of patients, a progression rate of 12.96% per year, 6.71% with the first year excluded. In a national collaboration of academic centers in Ireland, the progression rate for NDBE was similar to recent population studies. Almost one in two who progressed was evident within 1 year. Crucially, LGD diagnosed and confirmed by specialist gastrointestinal pathologists represents truly high-risk disease, highlighting the importance of expertise in diagnosis and management, and providing indirect support for ablative therapies in this context.

✓ The case is reported of meningioangiomatosis of the brain stem in a 3½-year-old girl who suffered from vomiting, left facial weakness, difficulty in swallowing, and ataxia. This is believed to be the first reported case of meningioangiomatosis in the brain stem. Computerized tomography showed an intensely enhancing hyperdense mass in the left restiform body. Magnetic resonance imaging revealed that the lesion was isointense to gray matter on the T1-weighted image and hypointense on the T2-weighted image, with a surrounding zone of high T2 signal and intense enhancement. Angiography was normal. Surgical exploration demonstrated an intramedullary firm mass that was partially resected. Histologically, the mass consisted of a low-grade lesion of meningeal origin with spindle cells in a whorling pattern that were occasionally focused around small vessels. On 2-year follow-up imaging, the lesion remains unchanged in size. Certain particularities of this lesion are discussed in the context of the literature.

Abstract Abstract 1937 Poster Board I-960 Background. Waldenstrom's macroglobulinemia is a rare B cell neoplasm characterized by the production of a monoclonal IgM protein and a lymphoplasmacytic infiltrate in the bone marrow. The clinical manifestations related to tumor infiltration include hepatomegaly (20%), splenomegaly (15%) and lymphadenopathy (15%). Organomegaly was associated with adverse prognosis in a large series of WM. More sensitive tools of tumor burden and prognosis are needed in these patients. The use of FDG-PET has not been previously studied in WM but has proved an effective diagnostic and prognostic tool in other in low-grade lymphomas. Therefore the objective of this study was to determine whether FDG-PET was an effective tool in evaluating pts with WM. Methods. We prospectively studied PET/CT in 39 WM patients homogeneously treated with bortezomib-rituximab (given IV bortezomib 1.6mg/m2 at days 1, 8, 15 q 28 days × 6 cycles and rituxan 375 mg/m2 at days 1, 8, 15, 22 on cycles 1 and 4) on a phase II clinical trial, at diagnosis (N=12) and with relapsed/refractory disease (N=27). All pts underwent staging evaluation by FDG-PET in combination with CT scan before and after therapy. PET results were analyzed as positive or negative. Response (ORR) was assessed after cycle 3, confirmed with 2 consecutive values and included minor response or better. Overall (OS) and treatment free survivals (TFS) were calculated from start of treatment to date of last follow up and time of next treatment, respectively. Results. The median age of the population was 62 years (range, 43-78), Male/Female ratio 1.64, WM-International staging score breakdown was 46% low, 23% intermediate, 31% high. Serum M-spike was 2.5g/L (0.41-4.62) with 8% patients >= 4g/L. The overall response rate was 89.7% with minor response in 13 pts and major response in 22 pts. With a median (+/-se) follow-up of 15 months (+/-1.22), death occurred in 2 patients, and the median OS was not reached with a 3-year probability of survival of 89%. The median TFS was 21 months (+/-2.09). Twenty-five (64.1%) and 13 (37.1%) patients had a positive PET before and after treatment, respectively. 11 (45.8%) patients had a negative post treatment PET which was positive before treatment, 1 (4.8%) had a positive PET after treatment while initially negative and all other patients had no change. Patients with positive PET before treatment had no clinical-biological difference (age, gender, hemoglobin level, serum beta 2-microglobulin value, platelet count, IgM spike and ISS-WM score) with other patients. A positive PET before treatment had no influence on either OS or TFS or ORR or MR. However, a normal PET after treatment, including a negative PET after treatment which initially was positive before treatment, correlated with response (p=0.04). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for a normal PET after treatment and for a negative PET after treatment while initially positive before treatment in predicting ORR were 68.7%, 100%, 100%, 23% and 52.4%, 100%, 100%, 23.1%, respectively. Although the number of deaths is low in this series, a positive PET after treatment was an adverse prognostic factor for OS. The median survival and the 2-year probability of survival was not reached and 100% for patients with a normal (negative) PET after treatment (number of death/number of pts in the group, O/N=0/22) while it was 20 months and 46% for patients with a positive PET after treatment (O/N=2/13 ), respectively (p=0.019). Conclusion: Over 60% of WM pts demonstrated FDG-avid disease when using FDG-PET scans with the majority showing negative imaging after therapy. PET positive scans after therapy correlated with poor prognosis. FDG-PET scans may prove an effective tool in the diagnosis and prognosis in WM. Disclosures: No relevant conflicts of interest to declare.

128 Background: For intact breast, the Harvard and LENTSOMA criteria are widely used to report late cosmesis. These scales require clinician’s interpretation and thus may be subject to variation between evaluators. Computerized tools exempt from evaluator bias are available to assess cosmesis. The objective of this study was to perform a comparative review of late breast cosmesis using the Harvard, LENTSOMA, and BCCT.core scales (Cardoso JS. et al; doi:10.1016/j.artmed.2007.02.007). Methods: A frontal bilateral breast photograph was used for analysis. Late cosmesis was scored with reference to the baseline breast appearance, ~ 1 year from RT distant from the acute treatment effects. Cosmesis was graded as excellent, good, fair, or poor using the Harvard scale. For LENTSOMA, only atrophy/retraction was assessed from the frontal breast photographs. The BCCT.core software was used as a validated tool for objectively scoring cosmesis and computes a score based on symmetry, color, and scar visibility. All outcomes were assessed by the same investigator (AW). Results: A total of 33 patients had 1-year baseline and follow up photographs. All were treated on a 3-week hypofractionated RT schedule, and none received chemotherapy. One hundred photographs, 1 to 5.7 years from end of RT, were scored. Late cosmesis among patients with good/excellent scores at 1-year remained unchanged by all 3 methods. Among patients graded as fair at 1-year, there was improvement in late comesis detected by Harvard and BCCT.core scoring. Late cosmesis by LENTSOMA criteria remained unchanged from baseline. Conclusions: Our experience suggests easy applicability of BCCT.core for scoring cosmesis in clinical practice. We observed no significant differences in cosmetic score by the methods used. However, these observations were made on a small cohort of patients and evaluation on a larger cohort is needed. The role of objective user-independent grading of cosmesis might be helpful in large comparative studies of clinical outcomes. [Table: see text]

Object Gangliogliomas comprise less than 1% of all brain tumors and occur most often in children. Therefore, there are a limited number of patients and data involving the use or role of adjuvant therapy after subtotal resections (STRs) of gangliogliomas. The objective of this study was to examine and review the Mayo Clinic experience of 88 patients with gangliogliomas, their follow-up, risk of recurrence, and the role of radiation therapy after STR or only biopsy. Methods Eighty-eight patients with gangliogliomas diagnosed between 1970 and 2007 were reviewed. Data on clinical outcomes and therapy received were analyzed. The Kaplan-Meier method was used to estimate progression-free survival (PFS) and overall survival. Results The median age at diagnosis was 19 years. The median potential follow-up as of June 2008 was 142 months (range 9–416 months). Fifteen-year overall survival was 94%, median PFS was 5.6 years, with a 10-year PFS rate of 37%. Progression-free survival was dramatically affected by extent of initial resection (p < 0.0001). Conclusions This single-institution retrospective series of patients with gangliogliomas is unique given its large cohort size with a long follow-up duration, and confirms the excellent long-term survival rate in this group. The study also shows the importance of resection extent on likelihood of recurrence. Patients with gangliogliomas who undergo STR or biopsy alone have poor PFS. Radiation therapy may delay time to progression in patients with unresectable disease.
