Abstract INTRODUCTION In independent clinical trials, ~30% of brain metastases recur locally after radiosurgery (BMRS). For these lesions, treatment with stereotactic laser ablation (SLA, also known as laser interstitial thermal therapy (LITT)) alone achieves a 12-month local control (LC12) of 54-85% while repeat SRS achieved LC12 of 54-79%. Here, we report favorable outcomes for BMRS treated with SLA followed by consolidation radiosurgery (SLA/cSRS). METHODS Clinical outcome of 18 patients with 19 histologically confirmed BMRS treated with SLA followed by consolidation SRS and >3 months follow-up were collected retrospectively across three institutions. Local control was defined as stability or decrease in contrast-enhancing (CE) and FLAIR volume. RESULTS SLA achieved ablation of 73-100% of the BMRS CE volumes. Consolidation hypo-fractionated radiosurgery (5 Gy x 5 or 6 Gy x 5) was carried out 16-40 days post-SLA (median of 26 days). With a median follow-up of 185 days (range: 93-1367 days) and median overall survival (OS) of 185 days (range: 99-1367 days), 100% LC12 was achieved. 13/18 (72%) patients that required steroid therapy prior to SLA/cSRS were successfully weaned off steroid by three months post-SLA/cSRS. Post-SLA, KPS declined for 3/19 (16%) patients and improved for 1/19 (5%) patients. No KPS changes occurred subsequent to consolidation SRS. There were no 30-day mortalities or wound complications. Two patients required re-admission within 30 days of SRS (severe headache that resolved with steroid therapy (n=1) and new-onset seizure (n=1)). Except for two patients who suffered histologically confirmed, local failure at 649 and 899 days, all other patients are either alive (n=6) or died from systemic disease progression (n=10). None of the treated patients developed symptomatic radiation necrosis. CONCLUSIONS This collaborative institutional experience support efficacy and safety of SLA followed by consolidation SRS as a treatment for BMRS. The treatment strategy warrants further investigations.

Abstract Introduction: The optimal treatment paradigm for brain metastasis that recurs locally after initial radiosurgery (BMRS) remains an area of active investigation. Here, we report outcomes for patients with BMRS treated with stereotactic laser ablation (SLA, also known as laser interstitial thermal therapy, LITT)followed by consolidation radiosurgery (cSRS). Methods: Clinical outcome of 20 patients with 21histologically confirmed BMRS treated with SLA followed by consolidation SRS and >6 months follow-up were collected retrospectively across three participating institutions. Results: Consolidation SRS (5 Gy x 5 or 6 Gy x 5) wascarried out 16-73 days (median of 26 days) post-SLA of BMRS. There were no new neurological deficits after SLA/cSRS. While 3/21 (14.3%) patients suffered temporary Karnofsky Performance Score (KPS) decline after SLA, no KPS declines was observed after cSRS. There were no 30-day mortalities or wound complications. Two patients required re-admission within 30 days of cSRS (severe headache that resolved with steroid therapy (n=1) and new onset seizure (n=1)). With a median follow-up of 228 days (range: 178-1367 days), the local control rate at 6 and 12 months (LC6, LC12) was 100%. All showed diminished FLAIR volume surrounding the SLA/cSRS treated BMRS at the six-month follow-up; none of the patients required steroid for symptoms attributable to these BMRS. These results compare favorably to the available literature for repeat SRS or SLA-only treatment of BMRS.Conclusions: This multi-institutional experience supports further investigations of SLA/cSRS as a treatment strategyfor BMRS.

Stereotactic Ablative Radiotherapy

Introduction: Liver metastases are common in patients with neuroendocrine neoplasms. The role of stereotactic ablative radiotherapy (SABR) is not well understood in this population. Objective: To evaluate the safety and efficacy of SABR in treating well-differentiated neuroendocrine liver metastases (WD-NELM). Methods: A retrospective review of patients with WD-NELM treated with SABR between January 2015-July 2019. Demographic, treatment and clinical/radiographic follow-up data were abstracted. RECIST 1.1 criteria were applied to each individual target to evaluate the response to treatment. Local control (LC) and progression free survival (PFS) were determined using Kaplan-Meier methodology. Toxicity was reported according to CTCAE v5.0. Results: Twenty-five patients with a total of 53 liver metastases treated with SABR were identified. Most patients (68%) had midgut tumors, were Grade II (80%) and had high volume intrahepatic and/or extrahepatic disease (76%). Median number of liver metastases treated was 2 with a median size of 2.5 cm. Median radiation dose delivered was 50Gy/5 fractions. Median follow-up was 14 months; 24 of the 25 patients were alive at time of analysis. The objective response rate (ORR) was 32%, with improvement or stability in 96% of lesions treated. The median time to best response was 9 months. The 1-year LC and PFS were 92% and 44% respectively. No Grade III/IV acute or late toxicity was identified. Conclusions: Liver SABR is a safe and promising means of providing local control for WD-NELM. This treatment modality should be evaluated in select patients in concert with strategies to manage systemic disease.

Abstract BACKGROUND: The standard treatment of resected brain metastasis is whole-brain radiotherapy (WBRT). To avoid the potential toxicity of WBRT and to improve local control, we have used radiosurgery alone to the surgical cavity. OBJECTIVE: To demonstrate the rates of local control, new intracranial metastasis, and overall survival using this treatment scheme without WBRT. METHODS: Eighty-five consecutive patients with brain metastasis were treated with surgical resection of at least 1 lesion followed by radiosurgery alone to the surgical cavity and any unresected lesions from August 2000 to March 2011. Sixty-eight percent had gross total resections. After surgery, radiosurgery was delivered to the surgical cavity with a 2- to 3-mm margin. The median marginal radiosurgery dose was 16 Gy, and median target volume was 13.96 cm3. Follow-up imaging and clinical examination were obtained every 2 to 3 months. RESULTS: Median follow-up time was 11.2 months. Overall local control was 81.2%. The 6-month, 1-year, and 2-year rates of local control were 88.7%, 81.4%, and 75.7%, respectively. Forty-seven patients (55%) developed new intracranial metastases at a median time of 5.6 months. For the entire population, the rate of new metastases was 32.1%, 58.1%, and 62.9% at 6 months, 1 year, and 2 years, respectively. Median overall survival time was 12.1 months. From initial treatment until death or last follow-up, only 30 patients (35%) received WBRT as salvage treatment. CONCLUSION: Radiosurgery to the surgical cavity without WBRT achieved excellent local control of resected brain metastasis. Close imaging follow-up allows early intervention for any new metastasis.

Plaque Brachytherapy

Purpose. To evaluate our community-based institutional experience with plaque brachytherapy for uveal melanomas with a focus on local control rates, factors impacting disease progression, and dosimetric parameters impacting treatment toxicity. Methods and Materials. Our institution was retrospectively reviewed from 1996 to 2011; all patients who underwent plaque brachytherapy for uveal melanoma were included. Follow-up data were collected regarding local control, distant metastases, and side effects from treatment. Analysis was performed on factors impacting treatment outcomes and treatment toxicity. Results. A total of 107 patients underwent plaque brachytherapy, of which 88 had follow-up data available. Local control at 10 years was 94%. Freedom from progression (FFP) and overall survival at 10 years were 83% and 79%, respectively. On univariate analysis, there were no tumor or dosimetric treatment characteristics that were found to have a prognostic impact on FFP. Brachytherapy treatment was well tolerated, with clinically useful vision (>20/200) maintained in 64% of patients. Statistically significant dosimetric relationships were established with cataract, glaucoma, and retinopathy development (greatest P=0.05). Conclusions. Treatment with plaque brachytherapy demonstrates excellent outcomes in a community-based setting. It is well tolerated and should remain a standard of care for COMS medium sized tumors.

The Impact

The median overall survival (OS) and local control (LC) of patients with melanoma brain metastases (MBMs) are poor even with immune checkpoint inhibitors and/or radiotherapy (RT). The aims of the study were to evaluate the association and timing of stereotactic radiotherapy (SRT)/radiosurgery (SRS) performed with the CyberKnife® System and ipilimumab (IPI). A total of 63 MBMs patients were analyzed: 53 received RT+IPI and 10 RT alone. Therefore, the patients were divided into four groups: RT PRE-PI (>4 weeks before IPI) (18), RT CONC-IPI (4 weeks before/between first and last cycle/within 3 months of last cycle of IPI) (20), RT POST-IPI (>3 months after IPI) (15), and NO-IPI (10). A total of 127 lesions were treated: 75 with SRS (one fraction) and 24 with SRT (three to five fractions). The median follow-up was 10.6 months. The median OS was 10.6 months for all patients, 10.7 months for RT+IPI, and 3.3 months for NO-IPI (p = 0.96). One-year LC was 50% for all patients, 56% for RT+IPI, and 18% for NO-IPI (p = 0.08). The 1-year intracranial control was 45% for all patients, 44% for RT+IPI, and 51% for NO-IPI (p = 0.73). IPI with SRS/SRT in MBMs treatment could improve LC. However, the impact and timing of the two modalities on patients’ outcomes are still unclear.

Flap Procedure

Introduction: Despite the available guidelines, opinions of many surgeons are quite ambiguous when it comes to the therapy of pilonidal sinus disease. The treatment can be a frustrating problem both for the surgeon and the patient because it is associated with wound complications and high recurrence rate. The objective of this study was to analyze the results of patients with pilonidal sinus disease undergoing the Karydakis flap procedure. Methods: A total of 27 patients treated for primary and recurrent pilonidal disease using the Karydakis flap procedure at our department between October 23, 2018 and November 22, 2019 were analyzed prospectively. We evaluated postoperative wound healing, complications and recurrence of the disease in a short-term follow-up period. Disease recurrence was defined as prolonged healing or as a new disease requiring repeated surgery. Results: In December 2019 all 27 patients came for a follow-up visit. The result was a fully lateralized wound without any signs of a new disease in all patients. In May 2020 a follow-up visit by phone was performed. The median follow-up was 12 months. The healing process was free of any serious complications in 25 patients. Seroma formation cases were managed by puncture in the outpatient setting. Conclusion: According to the available evidence and guidelines, off-midline procedures – the Karydakis flap, Bascom cleft lift, and Limberg flap procedures – are associated with lower recurrence rates and better wound healing. An important goal is to achieve complete wound lateralization and to change the configuration of the gluteal cleft by reshaping it, which results in a nicely flattened gluteal crease.

There are limited data on the relationship of acute dental infections with hospitalisation and new-onset atrial fibrillation (AF). This study aimed to assess the relationship between acute periapical abscess and incident AF. This was a retrospective cohort study from a French national database of patients hospitalized in 2013 (3.4 million patients) with at least five years of follow up. In total, 3,056,291 adults (55.1% female) required hospital admission in French hospitals in 2013 while not having a history of AF. Of 4693 patients classified as having dental periapical abscess, 435 (9.27%) developed AF, compared to 326,241 (10.69%) without dental periapical abscess that developed AF over a mean follow-up of 4.8 ± 1.7 years. Multivariable analysis indicated that dental periapical abscess acted as an independent predictor for new onset AF (p < 0.01). The CHA2DS2VASc score in patients with acute dental periapical abscess had moderate predictive value for development of AF, with Area Under the Curve (AUC) 0.73 (95% CI, 0.71–0.76). An increased risk of new onset AF was identified for individuals hospitalized with dental periapical abscess. Careful follow up of patients with severe, acute dental periapical infections is needed for incident AF, as well as investigations of possible mechanisms linking these conditions.

We aimed to evaluate the efficacy and toxicity of paclitaxel combined with pazopanib in advanced angiosarcoma (AS). The primary end point was progression-free survival (PFS) rate at six months (PFSR6). Planned accrual was 44 patients in order to detect a PFSR6 of >55%, with an interim futility analysis of the first 14 patients. The study did not meet its predetermined interim target of 6/14 patients progression-free at 6 months. At the time of this finding, 26 patients had been enrolled between July 2014 and April 2016, resulting in an overrunning of 12 patients. After a median follow-up of 9.5 (IQR 7.7–15.4) months, PFSR6 amounted to 46%. Two patients had a complete and seven patients a partial response. Patients with superficial AS had a significantly higher PFSR6 (61% vs. 13%, p = 0.0247) and PFS (11.3 vs. 2.7 months, p < 0.0001) compared to patients with visceral AS. The median overall survival in the entire cohort was 21.6 months. A total of 10 drug-related serious adverse effects were reported in 5 patients, including a fatal hepatic failure. Although our study did not meet its primary endpoint, the median PFS of 11.6 months in patients with superficial AS appears to be promising. Taking recent reports into consideration, future studies should evaluate the safety and efficacy of VEGFR and immune checkpoint inhibitors with or without paclitaxel in a randomized, multiarm setting.
