Abstract INTRODUCTION Medulloblastoma is one of the most common malignant brain tumors in children. To date, the treatment of average-risk (non-metastatic, completely resected) medulloblastoma includes craniospinal radiation therapy and adjuvant chemotherapy. Modern treatment modalities and now risk stratification of subgroups have extended the survival of these patients, exposing the long-term morbidities associated with radiation therapy. METHODS We performed a single-arm, multi-institution study, seeking to reduce the late effects of treatment in patients with average-risk medulloblastoma prior to advances in molecular subgrouping. To do so, we reduced the dose of craniospinal irradiation by 25% to 18 gray with the goal of maintaining the therapeutic efficacy as described in CCG 9892 with maintenance chemotherapy. RESULTS 28 patients aged 3–30 years were enrolled across three institutions between April 2001 and December 2010. Median age at enrollment was 9 years with a median follow-up time of 11.7 years. The 3-year relapse-free (RFS) and overall survival (OS) were 78.6% (95% CI 58.4% to 89.8%) and 92.9% (95% CI 74.4% to 98.2%), respectively. The 5-year RFS and OS were 71.4% (95% CI 50.1% to 84.6%) and 85.7% (95% CI 66.3% to 94.4%), respectively. Toxicities were similar to those seen in other studies; there were no grade 5 toxicities. CONCLUSIONS Given the known neurocognitive adverse effects associated with cranial radiation therapy, studies to evaluate the feasibility of dose reduction are needed. In this study, we demonstrate that select patients with average-risk medulloblastoma may benefit from reduced craniospinal radiation dose of 18 gray without impacting relapse-free or overall survival.

Pineal parenchymal tumors are rare. Of the three types of pineal parenchymal tumors, pineocytomas are the least aggressive and are not known to diffusely disseminate. In this paper, we report the successful treatment of a case of pineocytoma with diffuse leptomeningeal relapse following initial stereotactic radiotherapy. A 39-year-old female presented with headaches, balance impairment, urinary incontinence, and blunted affect. A pineal mass was discovered on magnetic resonance imaging (MRI). A diagnosis of pineocytoma was established with an endoscopic pineal gland biopsy, and the patient received stereotactic radiotherapy. Ten years later, she developed diffuse leptomeningeal dissemination. The patient was then successfully treated with craniospinal radiation therapy. Leptomeningeal spread may develop as late as 10 years after initial presentation of pineocytoma. Our case demonstrates the importance of long-term follow-up of patients with pineal parenchymal tumors following radiation therapy, and the efficacy of craniospinal radiation in the treatment of leptomeningeal dissemination.

9 Background: Small cell prostate cancer (SCPC) is a rare entity with treatment patterns extrapolated from small cell cancer of the lung. Outcomes have been evaluated in small series but prognostic factors are relatively poorly defined. Methods: We utilized the National Cancer Data Base to analyze men diagnosed with SCPC from 2004-2015. Only men with known clinical TNM staging, treatment modalities, and follow up were included. Overall survival (OS) was analyzed and compared with Kaplan-Meier, log-rank, and Cox proportional hazards ratios. Associations with baseline and tumor properties were performed with Chi-squared, independent t-test, and bivariate regression analyses. Results: 800 men with SCPC were identified. Median PSA was 79.0 ng/dL. 55.6% of men had cM1 disease at diagnosis, 31.4% had cN0M0 disease, and 13.0% were cN1M0. Median follow up was 12.4 months for all patients and 19.3 months for cM0 patients. Median survival for cM1, cN0M0, and cN1M0 patients was 9.8, 28.5, and 17.1 months, respectively (p<0.001). In cM0 patients, 66 (18.7%) underwent radical prostatectomy (RP), 177 (50.1%) received radiation therapy (XRT), and 195 (45.2%) received chemotherapy (CT). Median survival for men undergoing RP was not reached vs those who did not undergo RP (p<0.001). XRT also showed a trend towards improved median OS (25.2 vs. 19.1 months, p=0.139). On multivariable analysis for cM0 men, only age (HR 1.044 [95% CI 1.025-10.64] p<0.001), cN1 (HR 1.378 [95% CI 1.001-1.898] p=0.050, RP (HR 0.429 [95% CI 0.259-0.709] p=0.001), and XRT (HR 0.520 [95% CI 0.384-0.704] p<0.001) were predictive for overall survival. When examining only men who received systemic therapy, XRT was the only additional treatment modality to exhibit a survival benefit (HR 0.623 [95% CI 0.425-0.912] p=0.015). Of men with cM1 disease, 78 (17.5%) underwent definitive local therapy (RP/XRT), but no difference in OS was observed. Conclusions: Small cell prostate cancer is an aggressive disease with the majority of men presenting with metastases. In those with pelvis-confined disease who are fit for systemic therapy, radiation therapy to the primary should be considered.

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.

Long Term Follow Up

The efficacy of a short leg walking cast in the treatment of chronic plantar heel pain was assessed for 32 patients with 37 involved extremities treated over a 2-year period. All patients had failed numerous other treatment modalities and had been symptomatic for an average of 1 year. Long-term follow-up for 24 patients with 28 involved extremities revealed complete resolution of pain for 7 extremities (25%), improvement for 17 (61%), and no improvement for 4 (14%). Ten (42%) patients were completely satisfied with cast treatment, 3 (12%) were satisfied with reservations, and 11 (46%) were dissatisfied. Casting appears to be a reasonable option for patients with recalcitrant heel pain and should be offered before surgical intervention.
