Abstract Purpose Low-dose total skin electron beam therapy (TSEBT) over 3 weeks has proved to be a safe and effective treatment for cutaneous T cell lymphomas (CTCL). In this prospective trial, we examined the feasibility of ultra-hypofractionated low-dose TSEBT regimen in two fractions with 4 Gy combined with systemic therapy to minimize the number of visits to radiation centers. Patients and methods Six patients with mycosis fungoides (MF) or Sézary syndrome (SS) received TSEBT with a total radiation dose of 8 Gy in two fractions between April 2020 and June 2020. Patient and treatment characteristics, tumor burden, the impact on the quality of life using Skindex-29 questionnaires, and acute toxicities were analyzed. Results During TSEBT, all patients developed grade 1 toxicities while two patients developed grade 2 toxicities. One patient experienced sepsis. The most common adverse effects were erythema and edema. All grade 2 toxicities regressed after 4 weeks following TSEBT. Based on the reported symptoms measured by Skindex-29, we detected a significant reduction in total Skindex-29 score after 8 weeks of radiation (P = 0.03), particularly in the symptoms (P = 0.01) and emotional domains (P = 0.04). Conclusion Ultra-hypofractionated low-dose TSEBT followed by systemic therapy seems to be a safe and feasible alternative to conventional fractionated TSEBT for patients with MF/SS. The skin tumor burden and the health-related quality of life have been significantly improved within 8 weeks following radiotherapy.

The Impact

311 Background: Stereotactic ablative radiotherapy (SAbR) is a promising treatment option for selected oligometastatic renal cell carcinoma (RCC) patients that can provide longitudinal disease control while preserving quality of life. Retrospective data have shown a local control (LC) rate greater than 90% and longitudinal disease control of over a year without systemic therapy. However, prospective validation of SAbR for oligometastatic RCC is lacking. In this prospective phase II single arm trial, we evaluated the impact of SAbR on freedom from systemic therapy (FFST). Methods: Treatment naïve patients with RCC confirmed by pathology and radiographic evidence of three or fewer extracranial metastases received SAbR with curative intent to all measurable sites of disease. Follow-up included radiographic imaging at three-month intervals to assess disease control. The primary endpoint was FFST defined as time from SAbR to the initiation of systemic therapy. Secondary endpoints included LC, modified progression-free survival (mPFS) (time from first SAbR to progression not amenable to further SAbR), PFS on subsequent systemic therapy, cancer-specific survival (CSS), overall survival (OS), toxicity and health-related quality of life (QOL) indices as measured with EQ-5D-5L and FACT-G. A Wilcoxon signed-rank test was used to evaluate the QOL indices. Results: The trial completed accrual with the enrollment of 23 patients who received SAbR to a total of 38 sites. At a median follow-up of 12 months (interquartile range 1.8-16), 1-year FFST was 87% (95% CI: 56%-96%). The 1-year mPFS was 79% (95% CI:49%-93%), while the median mPFS has not yet been reached. Three patients had disease progression at individual time points of 3.5, 4.0, and 12 months. One of these patients developed brain metastases that were controlled with gamma knife radiosurgery without initiating systemic therapy. The LC, CSS, and OS were 100% (38/38), 100% (23/23), and 95% (22/23), respectively. When compared to baseline, no significant decline in QOL was detected. Three patients experienced treatment-related grade 1 toxicity; no ≥grade 2 toxicities were reported. One patient died of an unrelated cause. Conclusions: SAbR is a safe and effective treatment for oligometastatic RCC that can provide longitudinal disease control and preserve quality of life. These data support further evaluation of SAbR for oligometastatic RCC in a randomized study. Clinical trial information: NCT02956798 .

Purpose The purpose of this study was to identify levels of self-compassion in adults who do and do not stutter and to determine whether self-compassion predicts the impact of stuttering on quality of life in adults who stutter. Method Participants included 140 adults who do and do not stutter matched for age and gender. All participants completed the Self-Compassion Scale. Adults who stutter also completed the Overall Assessment of the Speaker's Experience of Stuttering. Data were analyzed for self-compassion differences between and within adults who do and do not stutter and to predict self-compassion on quality of life in adults who stutter. Results Adults who do and do not stutter exhibited no significant differences in total self-compassion, regardless of participant gender. A simple linear regression of the total self-compassion score and total Overall Assessment of the Speaker's Experience of Stuttering score showed a significant, negative linear relationship of self-compassion predicting the impact of stuttering on quality of life. Conclusions Data suggest that higher levels of self-kindness, mindfulness, and social connectedness (i.e., self-compassion) are related to reduced negative reactions to stuttering, an increased participation in daily communication situations, and an improved overall quality of life. Future research should replicate current findings and identify moderators of the self-compassion–quality of life relationship.
