RESUMO
BACKGROUND/AIM: Patients who receive radiotherapy (RT) may experience significant distress. This study investigated distress scores during RT for a variety of malignancies. PATIENTS AND METHODS: Distress thermometers (scores of 0-10 points) were completed by 927 patients at baseline and end of RT. Six characteristics were evaluated for changes of distress scores including age, sex, Karnofsky performance score (KPS), tumor type, intent of treatment, and previous RT. RESULTS: Mean distress scores were 4.9 (±2.7) at baseline and 4.6 (±2.7) at the end of RT; mean change was -0.3 (±2.8) points. On univariable analysis, increased distress (≥2 points) was significantly associated with KPS 90-100 (p<0.001) and curative intent (p=0.040). Trends were found for age ≤64 years (p=0.062), head-and-neck cancer (p=0.076), and no prior RT (p=0.055). In patients with baseline scores ≤5 points, deterioration rates were 30-47%. CONCLUSION: Psychological support should be offered to all patients undergoing RT. This would benefit particularly patients with risk factors for increased distress.

Radiotherapy of lung cancer may cause pneumonitis that generally occurs weeks or months following therapy and can be missed. This prospective trial aimed to pave the way for a mobile application (app) allowing early diagnosis of pneumonitis. The primary goal was the identification of the optimal cut-off of a score to detect pneumonitis of grade ≥2 after radiotherapy for lung cancer. Based on the severity of symptoms (cough, dyspnea, fever), scoring points were 0−9. Receiver operating characteristic (ROC)-curves were used to describe the sensitivity and specificity. The area under the ROC-curve (AUC) was calculated to judge the accuracy of the score, Youden-index was employed to define the optimal cut-off. Until trial termination, 57 of 98 patients were included. Eight of 42 patients evaluable for the primary endpoint (presence or absence of radiation pneumonitis) experienced pneumonitis. AUC was 0.987 (0.961−1.000). The highest sensitivity was achieved with 0−4 points (100%), followed by 5 points (87.5%), highest specificity with 5−6 points (100%). The highest Youden-index was found for 5 points (87.5%). The rate of patient satisfaction with the symptom-based scoring system was 93.5%. A cut-off of 5 points was identified as optimal to differentiate between pneumonitis and no pneumonitis. Moreover, pneumonitis was significantly associated with an increase of ≥3 points from baseline (p < 0.0001). The scoring system provided excellent accuracy and high patient satisfaction. Important foundations for the development of a mobile application were laid.
RESUMO
BACKGROUND/AIM: Very elderly patients irradiated for bone metastases likely benefit from individualized treatments. A specific survival score was created for this group and compared to existing instruments. PATIENTS AND METHODS: Ninety-six patients aged 80+ irradiated for bone metastases were retrospectively evaluated. Dose-fractionation regimen plus twelve characteristics were evaluated for survival. RESULTS: In the Cox regression model, performance status and tumor type were significant and used for the score, which included three groups (5-7, 8-12, and 14 points) with 6-month survival rates of 15%, 52%, and 90%. Positive predictive values (PPVs) regarding death ≤6 months were 85% (new score), 100% (previous 65+ score), and 84% (previous score for any age). The new instrument and the 65+ score were also very accurate regarding survival. Since PPV regarding death was calculated from only four patients for the 65+ score, this PPV may be less conclusive than that for the new instrument. CONCLUSION: The new score appears useful for patients aged 80+ irradiated for bone metastases.

Survival scores facilitate personalized cancer treatment. Due to demographic changes, very elderly patients are more prevalent than in the past. A score was developed in 94 patients aged ≥ 80 years undergoing whole-brain radiotherapy for brain metastases. Dose fractionation, treatment period, age, sex, performance score (ECOG-PS), tumor type, count of lesions, metastases outside the brain, and interval tumor diagnosis to radiotherapy were retrospectively evaluated. Independent predictors of survival were used for the score. Based on individual scoring points obtained from 3-month survival rates, prognostic groups were designed. Additionally, the score was compared to an existing tool developed in patients ≥ 65 years. ECOG-PS, count of lesions, and extra-cranial metastases were independent prognostic factors. Three groups were created (7, 10, and 13−16 points) with 3-month survival of 6%, 25%, and 67% (p < 0.001), respectively. Positive predictive values (PPVs) regarding death ≤ 3 and survival ≥ 3 months were 94% and 67% (new score) vs. 96% and 48% (existing tool), respectively. PPVs for survival ≥1 and ≥2 months were 88% and 79% vs. 63% and 58%, respectively. Both tools were accurate in predicting death ≤2, ≤3, and ≤6 months. The new score was more precise regarding death ≤1 month and survival (all time periods) and appeared preferable. However, it still needs to be validated.
RESUMO
BACKGROUND/AIM: Many cancer patients receive radiotherapy, which may cause distress. This pilot study evaluated distress levels before and after radiotherapy to contribute to the design of a prospective trial. PATIENTS AND METHODS: Two-hundred patients completed distress thermometers before and after radiotherapy. Distress levels ranged from 0 (no distress) to 10 (maximum distress). Five characteristics were retrospectively analyzed regarding changes of distress including age, sex, performance score, tumor type, previous radiotherapy, and treatment intention. Additional analyses were performed for elderly (>65 years) and non-elderly (≤65 years) patients. RESULTS: In all patients and both age groups, median pre-radiotherapy and post-radiotherapy distress levels were 5 (0-10) vs. 4 (0-10) points. Mean changes of distress levels were -0.5 (±2.6) points in all, -0.4 (±2.5) in elderly, and -0.7 (±2.8) in non-elderly patients. Changes were significantly associated with tumor type in all (p=0.049) and elderly (p=0.025) patients. CONCLUSION: Future studies investigating distress levels in patients receiving radiotherapy should consider age and tumor type.

Survival scores are important for personalized treatment of bone metastases. Elderly patients are considered a separate group. Therefore, a specific score was developed for these patients. Elderly patients (≥65 years) irradiated for bone metastases were randomly assigned to the test (n = 174) or validation (n = 174) cohorts. Thirteen factors were retrospectively analyzed for survival. Factors showing significance (p < 0.05) or a trend (p < 0.06) in the multivariate analysis were used for the score. Based on 6-month survival rates, prognostic groups were formed. The score was compared to an existing tool developed in patients of any age. In the multivariate analysis, performance score, tumor type, and visceral metastases showed significance and gender was a trend. Three groups were designed (17, 18−25 and 27−28 points) with 6-month survival rates of 0%, 51%, and 100%. In the validation cohort, these rates were 9%, 55%, and 86%. Comparisons of prognostic groups between both cohorts did not reveal significant differences. In the test cohort, positive predictive values regarding death ≤6 and survival ≥6 months were 100% with the new score vs. 80% and 88% with the existing tool. The new score was more accurate demonstrating the importance of specific scores for elderly patients.
RESUMO
BACKGROUND/AIM: Little is known regarding seizures during radiotherapy for brain tumors. This prospective study investigated seizure activity in patients irradiated for high-grade gliomas. PATIENTS AND METHODS: Using a seizure diary, progression of seizure activity was evaluated in 22 patients receiving chemoradiation for grade III (n=1) or IV (n=21) gliomas. Progression was defined as increased frequency of any and/or generalized seizures (>50%) or increased anti-epileptic medication (≥25%). Patients' satisfaction with the diary was assessed using a questionnaire (six scales of 1-7 points). Uni- and multivariable analyses were performed including baseline seizure activity, age, sex, resection, tumor site, performance score, and history of epilepsy/seizures. RESULTS: Ten patients (45%) experienced progression of seizure activity during their radiotherapy course, mainly due to increased seizure frequency (nine patients=41%). Mean values of patients' satisfaction scores ranged between 3.92 and 4.92 points. CONCLUSION: Radiotherapy of high-grade gliomas can increase seizure activity. Patients require close monitoring to initiate or adjust anti-epileptic medication.

BACKGROUND/AIM: Upcoming radiotherapy may cause distress and sleep disorders (SDO). This prospective interventional trial investigated SDO during a course of radiotherapy for breast cancer. PATIENTS AND METHODS: Fifty patients were eligible. The primary endpoint was improvement of SDO after 15 fractions. Additional endpoints included SDO after 5 fractions and at the end of radiotherapy (EOT). Additional characteristics were analysed including use of smartphones/tablets, age, body mass index, performance score, comorbidity score, surgery, distress score, and emotional/ physical/practical problems. RESULTS: After 15 fractions, 38% of patients reported improvement of SDO (p<0.0001). Improvement rates were 22% after 5 fractions (p=0.003) and 39% at EOT (p<0.0001). Moreover, a significant association was observed for lower distress score after 5 fractions. CONCLUSION: Improvement of SDO occurred more often than expected, most likely due to habituation to radiotherapy. Since SDO did not improve in the majority of patients, timely psychological support should be offered to all patients.
