Background/Aim: Many patients with non-small cell lung cancer (NSCLC) receive palliative radiotherapy (RT). Several factors were analyzed to aid in prescribing an optimal treatment for these patients. Patients and Methods: This prospective observational multicenter study investigated several potential factors for associations with overall survival (OS) in 61 patients with NSCLC receiving palliative RT with or without chemotherapy (CT). Investigated factors included age, sex, performance status, history of smoking or alcohol, hemoglobin, co-morbidities, different clinical symptoms, and quality-of-life aspects. Results: Median OS was 10.8 months, and OS rates at 6, 12, and 24 months were 58.5%, 42.5%, and 28.4%, respectively. On multivariate analysis, RT alone (without CT), RT doses <= 30 Gy, advanced tumor stage (stage

Purpose To evaluate toxicity, prostate-specific antigen (PSA) kinetics, and cancer control of high-dose-rate brachytherapy (HDR-BT) as a salvage modality for men with locally recurrent prostate cancer, after primary HDR-BT failure. Material and methods Twelve patients with biochemical failure and a local relapse after 19 Gy single-fraction high-dose-rate brachytherapy (HDR-BT 19 Gy) were salvaged using two HDR-BT fractions. Salvage treatment consisted of two HDR-BT applications, one week apart, delivering 12 Gy to the prostate per application (HDR-BT 12 × 2). Results Median age and initial PSA prior to rescue treatment were 74 years (range, 65-80) and 5.29 ng/ml (range, 2.37-16.40), respectively. Forty-two percent had a low-risk and 58% presented with intermediate-risk prostate cancer. Median follow-up period was 26 months (range, 10-42). Median time to PSA nadir was 12 months, with a median value of 0.21 ng/ml. Most of the patients (11 of 12) achieved a PSA decline ≥ 90%. Acute grade 2 genitourinary (GU) toxicity occurred in 4 patients (33.3%) and none presented with acute gastrointestinal (GI) toxicity. Two patients (16.7%) suffered from late GU grade 2 toxicity. No grade 3 toxicity were recorded. To date, 2 patients (16.7%) have experienced biochemical failure after salvage treatment. Conclusions Salvage HDR-BT 12 × 2 is a feasible and well-tolerated treatment, with acceptable toxicity rates for men with locally recurrent prostate cancer, who failed after HDR-BT with 19 Gy. Moreover, PSA kinetics and cancer control after salvage treatment suggest that this strategy might be efficacious in this clinical setting.

INTRODUCTION:To assess pain response rate (RR) and quality of life (QoL), in patients with moderate/severe neuropathic pain (NP) due to bone metastasis (BM) undergoing palliative 3D radiotherapy plus tapentadol.METHODS:We conducted a prospective multicentre pilot study. Patients were assessed before radiotherapy using the validated questionnaire (Douleur Neuropathique en 4 questions). Response to radiotherapy (8 Gy-30 Gy/1-10fr) at one and two months was assessed according the International Bone Metastases Consensus criteria.INCLUSION CRITERIA:radiological evidence of BM, NP according to DN4 (cut-off score ≥ 4), no spinal cord compression, worst pain score ≥ 5/10. Nonparametric Mann-Whitney U test compared changes in QoL among response groups.RESULTS:Seventeen patients (13 men, 4 woman), median age 67 years (42-81), were included. Pre-treatment median pain severity was 7.5 (5-10). Median dose of tapentadol administered before radiotherapy was 100 mg/24 h (100-300 mg). Overall RR 1 month after radiotherapy was 10/16 = 62.5%: 3/16 (18.8%) achieving a complete response (CR) and 7/16 (43.8%) a partial response (PR). Overall RR 2 months after RT was 5/10 (50%): 10% a CR and 40% a PR. ITT RR for this study at 1 and 2 months was 10/17 = 59% and 5/17 = 29%, respectively. Patients responding to radiotherapy had significant improvement in EORTC QLQ-C30 emotional functioning (EF) (p = 0.025) and fatigue symptom scale scores (p = 0.035) one month after radiotherapy. Painful site symptom QLQ-BM22 scores improved 2 months after radiotherapy (p = 0.024).CONCLUSIONS:Palliative radiotherapy plus tapentadol shows an acceptable pain response and QoL improvement especially regarding EF, fatigue and painful site symptom scales in patients with moderate/severe NP due to BM. Therefore, it could be an alternative to manage NP in daily practice.

Purpose: To describe the genitourinary (GU) and gastrointestinal (GI) late toxicity profile and to analyse the clinical and dosimetry outcomes predictors of the combination of EBRT and high-dose-rate (HDR) prostate brachytherapy (BT) for localized prostate cancer. Materials and methods: Between January 2012 and May 2017, 210 patients were included in a prospective protocol. Treatment consisted in HDR-BT (15 Gy single fraction) plus 3DCRT (37.5 Gy/15 fractions). Univariate and multivariate logistic regressions were used to analyse the impact of variables on late toxicity. Results: Median age was 71 (56-82), 12.4% of patients had low, 44.3% intermediate and 41% high-risk prostate cancer. Median prostate volume was 28.4 cc. Median V100, V150, V200 were 98.2%, 27% and 7.4% respectively. Median urethra Dmax, rectum D1cc and D2cc, were 113.5%, 62.2%% and 54.2% respectively. After a median follow-up of 41 months (5-75) late G2 GU and GI late toxicity was observed in 14.8% and 5.2% of patients respectively. Late G3 GU and GI toxicity occurred in 0% and 1% of patients respectively. There were no outcome correlations with late G >= 2 GU toxicity on univariate analysis. Previous cardio-vascular comorbidity (p = 0.042), and dose to the rectum D2cc (p = 0.016) and D1cc (p = 0.017) were associated with G >= 2 GI toxicity. Multivariate analysis showed that rectum D1cc (HR11.56; 95% CI 1.4-92.1; p = 0.021) and prior history of cardiovascular disease (HR3.6; 95% CI 1-12.9; p = 0.045) remained independent predictors of G >= 2 GI toxicity. Conclusions: There is a low incidence of late GU and GI morbidity using single fraction HDR-BT and hypofractionated EBRT. Previous cardiovascular disease and dose to the rectum were observed to correlate with GI toxicity. (C) 2019 Elsevier B.V. All rights reserved.
