Background This study evaluates the association of adjuvant radiation therapy (RT) with improved locoregional (LR) recurrence for resected melanoma satellitosis and in-transit disease (ITD). Materials and Methods Data were collected retrospectively for resected melanoma satellitosis/ITD from 1996 to 2017. Results 99 patients were identified. 20 patients (20.2%) received adjuvant RT while 79 (79.8%) did not. Mean follow-up in the RT group was 4.3 years and 4.7 years in the non-RT group. 80% of patients who underwent RT suffered a complication, most commonly dermatitis. Locoregional recurrence occurred in 9 patients (45%) treated with adjuvant RT and 30 patients (38%) in the non-RT group ( P = 0.805). Median LR-DFS was 5.8 years in the RT group and 9.5 years in the non-RT group ( P = 0.604). On multivariable analysis, having a close or positive margin was the only independent predictor of LR-DFS (HR 3.8 95% CI 1.7-8.7). In-transit disease was associated with improved overall survival when compared to satellitosis (HR 0.260, 95% CI 0.08-0.82). Discussion The use of adjuvant RT is not associated with improved locoregional control in resected melanoma satellitosis or ITD. Close or positive margin was the only treatment-related factor associated with decreased LR-DFS after surgical resection of satellitosis/ITD.

103 Background: While three prospective trials have demonstrated benefit from adjuvant radiation (XRT) after radical prostatectomy (RP) in patients with positive surgical margins (PSM), its use varies amongst physicians. Many rely on clinical acumen to determine the optimal strategy for application of XRT post RP. We aim to determine if the length of PSM and highest Gleason grade (GG) of tumor at the PSM (hGGPSM) can be used to identify patients at greatest risk of biochemical failure (BCF) post RP. Methods: A retrospective review of all RP patients at The University of Texas MD Anderson Cancer Center from 2002 to 2010 was performed. After a single pathologist review, patients with organ confined disease (pT2), pathologic N0/Nx and a PSM were included. BCF was defined as 2 sequential PSA values of ≥0.2 or any detectable PSA prompting XRT. Patients receiving adjuvant XRT or with <12 months follow-up were excluded. Results: 205 patients met the inclusion criteria. Median PSA was 5.3 ng/mL (0.5-33) and median follow-up was 64 months (13-130). The majority were low clinical stage (cT1c: 65%), low (11%)/intermediate (82%) grade and had a single site of a PSM (90%). BCF occurred in 47 patients for a 5 yr BCF free survival (BCFFS) of 69%. PSM length was significantly associated with BCFFS (≤1mm vs >1, p=0.02). When accounting for hGGPSM, Gl 3 tumors were less likely to experience BF (5 yr BCFFS-96%) regardless of PSM length, while BCFFS for Gl >3 tumors were significantly lower dependent upon length of PSM ( ≤1mm vs >1mm, p=0.03). On multivariable analysis length of PSM (p=0.05) and hGGPSM (p=0.007) remained independent predictors of BCF (Table). Conclusions: Length of PSM and hGGPSM are independent predictors of BCF. These should be considered when evaluating patients for adjuvant XRT and in risk stratifying patients in prospective clinical trials. [Table: see text]

370 Background: In patients with muscle-invasive bladder cancer, local-regional failure (LF) has been reported to occur in up to 20% of patients following radical cystectomy. The goals of this study were to describe patterns of LF, as well as assess factors associated with LF in a cohort of patients with pT3-4 bladder cancer. This information may have implications towards the use of adjuvant radiation therapy. Methods: Patients with pathologic T3-4 N0-1 bladder cancer were examined from an institutional radical cystectomy database. Preoperative demographics and pathologic characteristics were examined. Outcomes included overall survival and LF. Local-regional failures were defined using follow-up imaging reports and scans, and the locations of LF were characterized. Variables were tested by univariate and multivariable analysis for association with LF and overall survival. Results: 334 patients had pT3-4 and N0-1 disease after radical cystectomy and bilateral pelvic lymph node dissection. Of these, 46% received perioperative chemotherapy. The median age was 71 and median follow up was 11 months. On univariate analysis, margin status, pT stage, pN stage, and gender were all associated with LF (p < 0.05), however, on multivariable analysis, only pT and pN stage were significantly associated with LF (p < 0.01). Three strata of risk were defined, including low-risk patients with pT3N0 disease, intermediate-risk patients with pT3N1 or pT4N0 disease, and high-risk patients with pT4N1 disease, who had 2-year incidence of LF of 12%, 33%, and 72%, respectively. The most common sites of pelvic relapse included the external/internal iliac LNs and obturator LN regions. Notably, 34% of patients with LF had local-regional only disease at the time of recurrence. Conclusions: Patients with pT4 or N1 disease have a 2-year risk of LF that exceeds 30%. These patients may be the most likely to benefit from local adjuvant therapies.

Adjuvant Radiation Therapy

133 Background: 20% of men with prostate cancer (PCa) are diagnosed with high-risk disease. The optimal therapy for these patients, prostatectomy followed by adjuvant radiation therapy (ART) or definitive radiation with androgen deprivation (DRT), is still unclear. Previous randomized trials failed to accrue; therefore we sought to answer this using an IRB-approved retrospective cohort study. Methods: High-risk PCa was defined using NCCN criteria. Adjuvant radiation was defined as radiotherapy started within 6 months of prostatectomy. Biochemical progression-free survival (BPFS), castrate resistance-free survival (CRFS), distant metastasis-free survival (DMFS), prostate cancer-specific survival (PCSS), and overall survival (OS) were calculated using Kaplan-Meier estimates. Biochemical failure was defined using the AUA definition in the ART group and by the Phoenix definition in the DRT group. Castrate resistance was defined as ≥2 episodes of rising PSA with testosterone <50 ng/ml or rising PSA despite second line anti-androgen. Statistical analysis was performed using log rank and Cox testing. Results: 60 men with high-risk PCa treated between 1992-2011 were included in the ART group and 154 men were included in the DRT group. 58% of men in the ART group received short course of androgen depravation therapy (ADT). Nearly all men received 2 years of ADT in the DRT group. The median follow up for the ART group was 62 months and 55 months for the DRT group. Men in ART group were younger (p<0.0001) and had a lower pre-treatment PSA (p=0.0338). Log rank testing revealed the ART group had worse BPFS (5 year: 57% vs. 71%; p=0.008), but there was no difference in the other endpoints including CRFS (p=0.9693), DMFS (p=0.7345), PCSS (p=0.5481), or OS (p=0.2557). On multivariable analysis ADT use, ADT length, type of treatment, and stage were not predictive of BRFS whereas Gleason score was (p=.0001). Conclusions: This study suggests that for high-risk PCa patients there is no difference between DRT and ART with regards to BPFS, CRFS, DMFS, PCSS, or OS. Therefore, over a short follow-up period, there does not appear to be a difference between these approaches. Prospective trials are required to validate this finding.

Transsphenoidal Resection

Benign notochordal cell tumors (BNCTs) are considered to be benign intraosseous lesions of notochord origin; however, recent spine studies have suggested the possibility that some chordomas arise from BNCTs. Here, the authors describe two cases demonstrating histological features of BNCT and concomitant chordoma involving the clivus, which, to the best of the authors’ knowledge, have not been previously documented at this anatomical site.An 18-year-old female presented with an incidentally discovered clival mass. Magnetic resonance imaging revealed a 2.8-cm nonenhancing lesion in the upper clivus that was T2 hyperintense and T1 hypointense. She underwent an uneventful endoscopic transsphenoidal resection. Histologically, the tumor demonstrated areas of classic chordoma and a distinct intraosseous BNCT component. The patient completed adjuvant radiation therapy. Follow-up showed no recurrence at 18 months.A 39-year-old male presented with an incidentally discovered 2.8-cm clival lesion. The nonenhancing mass was T2 hyperintense and T1 hypointense. Surgical removal of the lesion was performed through an endoscopic transsphenoidal approach. Histological analysis revealed areas of BNCT with typical features of chordoma. Follow-up did not demonstrate recurrence at 4 years.These cases document histologically concomitant BNCT and chordoma involving the clivus, suggesting that the BNCT component may be a precursor of chordoma.

Background:Uterine leiomyosarcoma (LMS) is associated with high rate of recurrence after surgical resection. The role of adjuvant radiation therapy in improving survival in women with uterine LMS is unclear.Methods:All cases of LMS treated from 1985 to 2005 at 11 regional medical centers were identified. Kaplan-Meier survival curves were constructed and compared with log-rank testing. Multivariate analysis was performed to account for the potential influence of confounding factors.Results:One hundred forty-seven patients with LMS were identified. The median age of diagnosis was 51 years with the stage distribution of stage I (n = 87), II (n = 9), III (n = 25), IV (n = 25), and unknown (n = 1). One hundred forty-three underwent total abdominal hysterectomy and bilateral salpingoophorectomy. Twenty-four (17%) of these patients received adjuvant pelvic irradiation, and 63 (44%) received adjuvant and/or palliative chemotherapy. With a median follow-up of 24 months (range, 1-249 months), the median survival for the entire group was 37 months. Cox proportional hazards modeling demonstrated the presence of high tumor grade and advanced stage adversely affected survival. Although the 5-year survival for patients who received adjuvant radiotherapy was significantly higher than those who did not (70% vs 35%), this survival advantage was not sustained as the curves crossed at 90-month follow-up. Pelvic recurrence rate was lower in the radiation group (18% vs 49%; P = 0.02).Conclusions:Adjuvant radiation therapy was associated with decreased pelvic failure and a modest improvement in 5-year survival, but did not impact overall survival with extended follow-up.

✓ The practice of neuroendoscopy in the definitive management of cystic tumors and hydrocephalus has been well established. Resection of solid intraventricular tumors by a primary endoscopic technique, however, has rarely been demonstrated. The authors present the case of a 31-year-old woman in whom endoscopic resection of a posterior third ventricular ependymoma was successfully accomplished. Metastatic workup yielded no sites of dissemination, adjuvant radiation therapy was deferred, and the patient has been without radiographic evidence of disease after 6 months of follow up. Endoscopic resection of solid tumors appears feasible in select patients and warrants further evaluation.

Abstract Patients undergoing transcatheter aortic valve replacement (TAVR) may have concomitant mitral regurgitation (MR). The impact of MR at baseline or after TAVR on subsequent prognosis remains to be more precisely determined. We analysed the impact of MR before or after TAVR on prognosis in the systematic analysis of patients treated with TAVR at a nationwide level. Methods Based on the French administrative hospital-discharge database, the study collected information for all consecutive patients with aortic stenosis treated with transfemoral TAVR in France between 2008 and 2018. Cox regression was used for the analysis of predictors of events during follow-up. Results A total of 47,872 patients with transfemoral TAVR were included in the analysis (mean age 83±7 years). Moderate/severe MR was present at baseline (MRb) in 9.5% of the patients. Few patients (1.6%) revealed moderate/severe MR post-TAVR (MRpt). Mean follow-up was 1.31±1.61 years. MRb was associated with an increased cardiovascular mortality (Hazard ratio 1.29, 95% CI 1.20–1.39) and total mortality (Hazard ratio 1.15, 95% CI 1.10–1.21). However, MRb was not an independent predictor in multivariable analysis, neither for cardiovascular mortality (adjusted HR 1.06, 95% CI 0.98–1.14) nor for total mortality (adjusted HR 1.01, 95% CI 0.96–1.07). MRpt was not a predictor of cardiovascular or total mortality. Older age, male sex, history of pulmonary edema/cardiogenic shock, atrial fibrillation, myocardial infarction, diabetes, renal failure, liver disease, pulmonary disease, previous cancer and anemia at baseline independently predicted mortality during follow-up. All of them (but history of cancer) were also independent predictor of cardiovascular death. Conclusion Baseline MR was associated with increased cardiovascular and totality mortality following TAVR but was not an independent predictor of any of them. By contrast, several other predictors of cardiovascular and total mortality were identified. This suggests that MR should not be directly considered to establish the strategy for TAVR decision or for avoiding TAVR-related futility.

e21521 Background: Adjuvant radiation therapy is an essential part of combined limb sparing treatment of STS. The recommended dose of radiation lies in the range of 60 Gy in standard fractionation of 1.8-2 Gy. Elderly or medically unfit patients often have difficulty in completing 6-7w of daily treatment. A prolonged course of radiation may be interrupted by acute side effects, which sometimes demands further extension of the overall course or even discontinuation of treatment. We intended to evaluate the efficacy of a hypofractionated adjuvant approach with radiation therapy for STS in the elderly and debilitated patients. Methods: 21 elderly patients were treated with a short course of adjuvant RT (39 to 48 Gy, 3 Gy per fraction) for STS. The medical records of the patients were retrospectively reviewed for the local or distant recurrence and side effects of RT. Results: Overall, the hypofractionated irradiation regimen of 39-48 Gy in 13-16 fractions was well tolerated with only 3 patients developing Grade 2-3 acute toxicity (mainly dermatitis). Three patients suffered from delayed Grade 2-3 toxicity (chronic pain, skin atrophy, teleangiectasiae) scaled according to CTSC. The mean time from the surgery until the initiation of RT was 65 days (SD 21.6). Mean RT time was 18.4 (SD 3) days. No delay of treatment due to acute toxicity was registered. All patients except for one were able to receive RT in the ambulatory setting. With a mean follow-up of 532 days (SD: 325), three local recurrences (14%) were detected. Three of eight patients with distant metastases died of sarcoma (graph 1). One patient with metastatic disease in the lung received salvage stereo tactic radiation therapy and was still alive 6 month after completion of SBRT with no evidence of disease. At a mean 532 days of follow up three local recurrences (14%) were detected .Eight patients (38%) had lung metastases during the observed period. Three of them died from metastatic disease. The hypofractionated radiation was well tolerated with minimum long term side effects. Conclusions: Hypofractionated adjuvant radiation appears to be an effective treatment in terms of local control in elderly and debilitated patients.
