Fatigue After Traumatic Brain Injury: A Systematic Review.

OBJECTIVE: To provide a systematic review of published interventions for posttraumatic brain injury fatigue (PTBIF). METHODS: PubMed and OneSearch were systematically searched for PTBIF interventions published between January 1, 1989, and March 31, 2019. Search results were evaluated for inclusion based on an abstract and full-text review. Inclusion criteria were (1) an investigation of an intervention, (2) participant sample including individuals with traumatic brain injury (TBI), (3) report of fatigue outcome data among individuals with TBI, and (4) articles available in English, Spanish, French, German, Afrikaans, or Dutch. A risk of bias assessment was conducted on all included publications. RESULTS: The search resulted in 2343 publications, with 37 meeting inclusion criteria for this review. Categories of PTBIF interventions were pharmacological ( n = 13), psychological ( n = 9), exercise-based ( n = 4), complementary alternative medicine ( n = 5), electrotherapeutic ( n = 3), and multimodal ( n = 3). Only methylphenidate, modafinil, and cognitive behavioral therapy interventions included multiple cohorts. Pharmacological and psychological interventions represented the groups with the lowest risk of bias. CONCLUSIONS: This review includes 37 studies, with 21 studies published after 2014. Methylphenidate and melatonin were the only pharmacological agents found to reduce fatigue in randomized controlled trials. Creatine given to children prospectively at onset of injury reduced fatigue at follow-up. Walking and water aerobics were effective exercise interventions in isolated randomized controlled studies. One multimodal study of children after concussion was more effective at reducing fatigue and postconcussion symptoms than community standard of care. Other interventions had equivocal results. Overall, more work remains to understand and develop treatments for PTBIF.

The UK Standardisation of Breast Radiotherapy (START) trials of radiotherapy hypofractionation for treatment of early breast cancer: 10-year follow-up results of two randomised controlled trials.

BACKGROUND: 5-year results of the UK Standardisation of Breast Radiotherapy (START) trials suggested that lower total doses of radiotherapy delivered in fewer, larger doses (fractions) are at least as safe and effective as the historical standard regimen (50 Gy in 25 fractions) for women after primary surgery for early breast cancer. In this prespecified analysis, we report the 10-year follow-up of the START trials testing 13 fraction and 15 fraction regimens. METHODS: From 1999 to 2002, women with completely excised invasive breast cancer (pT1-3a, pN0-1, M0) were enrolled from 35 UK radiotherapy centres. Patients were randomly assigned to a treatment regimen after primary surgery followed by chemotherapy and endocrine treatment (where prescribed). Randomisation was computer-generated and stratified by centre, type of primary surgery (breast-conservation surgery or mastectomy), and tumour bed boost radiotherapy. In START-A, a regimen of 50 Gy in 25 fractions over 5 weeks was compared with 41·6 Gy or 39 Gy in 13 fractions over 5 weeks. In START-B, a regimen of 50 Gy in 25 fractions over 5 weeks was compared with 40 Gy in 15 fractions over 3 weeks. Eligibility criteria included age older than 18 years and no immediate surgical reconstruction. Primary endpoints were local-regional tumour relapse and late normal tissue effects. Analysis was by intention to treat. Follow-up data are still being collected. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN59368779. FINDINGS: START-A enrolled 2236 women. Median follow-up was 9·3 years (IQR 8·0-10·0), after which 139 local-regional relapses had occurred. 10-year rates of local-regional relapse did not differ significantly between the 41·6 Gy and 50 Gy regimen groups (6·3%, 95% CI 4·7-8·5 vs 7·4%, 5·5-10·0; hazard ratio [HR] 0·91, 95% CI 0·59-1·38; p=0·65) or the 39 Gy (8·8%, 95% CI 6·7-11·4) and 50 Gy regimen groups (HR 1·18, 95% CI 0·79-1·76; p=0·41). In START-A, moderate or marked breast induration, telangiectasia, and breast oedema were significantly less common normal tissue effects in the 39 Gy group than in the 50 Gy group. Normal tissue effects did not differ significantly between 41·6 Gy and 50 Gy groups. START-B enrolled 2215 women. Median follow-up was 9·9 years (IQR 7·5-10·1), after which 95 local-regional relapses had occurred. The proportion of patients with local-regional relapse at 10 years did not differ significantly between the 40 Gy group (4·3%, 95% CI 3·2-5·9) and the 50 Gy group (5·5%, 95% CI 4·2-7·2; HR 0·77, 95% CI 0·51-1·16; p=0·21). In START-B, breast shrinkage, telangiectasia, and breast oedema were significantly less common normal tissue effects in the 40 Gy group than in the 50 Gy group. INTERPRETATION: Long-term follow-up confirms that appropriately dosed hypofractionated radiotherapy is safe and effective for patients with early breast cancer. The results support the continued use of 40 Gy in 15 fractions, which has already been adopted by most UK centres as the standard of care for women requiring adjuvant radiotherapy for invasive early breast cancer.

Comparison of patient-reported breast, arm, and shoulder symptoms and body image after radiotherapy for early breast cancer: 5-year follow-up in the randomised Standardisation of Breast Radiotherapy (START) trials.

BACKGROUND: Few trials of adjuvant breast radiotherapy have incorporated patient-reported breast symptoms and related areas of quality of life. We assessed these measures in a quality-of-life study that was part of the randomised START (Standardisation of Breast Radiotherapy) trials. METHODS: In START trial A, 2236 patients were randomly assigned to receive either 39 Gy or 41.6 Gy delivered in 13 fractions over 5 weeks or a global standard of 50 Gy in 25 fractions. In START trial B, 2215 women were randomly assigned to receive either 40 Gy in 15 fractions over 3 weeks or the same control regimen (50 Gy in 25 fractions) as in trial A. 2739 patients were eligible for the quality-of-life study of whom 2208 (81%) were accrued (1129 patients from trial A and 1079 from trial B). Participants completed the EORTC QLQ-C30 and BR23 questionnaires and protocol-specific radiotherapy items up to 5 years after radiotherapy. We compared results across regimens with generalised estimating equations and survival analyses. The START trials are registered, ISRCTN59368779. FINDINGS: At 5 years, up to 40% women reported moderate or marked changes to the breast after radiotherapy, and arm and shoulder pain affected up to a third of patients. Breast symptoms and body image concerns reduced over time. Rates of radiotherapy adverse effects were lower for the 39 Gy regimen in trial A and the 40 Gy regimen in trial B, compared with the 50 Gy control regimen; rates of radiotherapy adverse effects were similar between the 41.6 Gy and 50 Gy regimens in trial A. Adverse change in skin appearance was significantly lower for patients who received 39 Gy compared with those who received 50 Gy (HR 0.63, 95% CI 0.47-0.84) and for those who received 40 Gy compared with those who received 50 Gy (0.76, 0.60-0.97); no significant difference was observed between patients who received 41.6 Gy and those who received 50 Gy in trial A (0.83, 0.63-1.08). Patient self-ratings of breast symptoms discriminated a 10% difference in randomised dose intensity. Up to a third of women reported moderate or marked pain in the arm and shoulder over 5 years whilst more than 10% experienced moderate or marked arm and hand swelling, with no significant difference in arm/shoulder subscale scores between the regimens in trial A or trial B; many baseline arm and shoulder symptoms were associated with prior surgery. INTERPRETATION: A substantial proportion of women report moderate or marked breast, arm, and shoulder symptoms over 5 years of follow-up after radiotherapy, but with no detriment to body image. Nonetheless, most patients stand to gain from hypofractionated radiotherapy regimens with a potential for fewer adverse effects; this strengthens the evidence from the START trials for hypofractionated regimens for women requiring radiotherapy for early breast cancer.

The impact of age and clinical factors on quality of life in early breast cancer: an analysis of 2208 women recruited to the UK START Trial (Standardisation of Breast Radiotherapy Trial).

Quality of life (QOL) assessments of women entering a UK randomised trial of adjuvant radiotherapy (START) were investigated to estimate the independent effects on QOL of age, time since surgery, type of breast surgery, chemotherapy and endocrine therapy. QOL was evaluated using the EORTC general cancer QOL scale (EORTC QLQ-C30), breast cancer module (BR23), the Body Image Scale (BIS) and the Hospital Anxiety and Depression Scale (HADS). Independent effects of age and clinical factors were tested using multiple regression analysis. A total of 2208 (mean age 56.9 years, range 26-87) consented to the QOL study prior to radiotherapy; 17.1% had undergone mastectomy (Mx) and the remainder had undergone a wide local excision (WLE). 33.3% had received adjuvant chemotherapy (CT) and 56.7% were taking endocrine therapy (ET). Age had significant effects on QOL with older and younger subgroups predicting poorer QOL for different domains. CT affected most QOL domains and resulted in worse body image, sexual functioning, breast and arm symptoms (<0.001). Mx was associated with greater body image concerns (p<0.001), and WLE with more arm symptoms (p=0.01). There were no effects of ET on QOL. Women <50 years (proxy pre-menopausal) had worse QOL in respect of anxiety, body image and breast symptoms but age and clinical factors had no effect on depression. Overall, QOL and mental health were favourable for most women about to start RT, but younger age and receiving CT were significant risk factors for poorer QOL, and so patients in these subgroups warrant further monitoring. Surgery had a limited impact and ET had no effect on QOL.

The course of anxiety and depression over 5 years of follow-up and risk factors in women with early breast cancer: results from the UK Standardisation of Radiotherapy Trials (START).

Prospective data are limited on the course of anxiety and depression and their determinants in women with early breast cancer. These parameters were assessed before adjuvant radiotherapy (RT) and over 5 years follow-up. Of 2208 women recruited to the START QOL study, 35% reported clinically relevant levels of anxiety and/or depression pre-RT; there was no significant change in these proportions over time. However, 75% women with high baseline anxiety recorded further high scores over time whilst one in six had high scores at every follow-up point. Depression showed a similar pattern with lower frequencies at all time points; very few with initial normal scores developed clinically relevant anxiety or depression over time. Lower educational level predicted worse anxiety and depression over time; younger age predicted worse anxiety and chemotherapy predicted worse depression. Scores in the borderline or case range for anxiety or depression at baseline were both significantly associated with worse mood states over 5 years. These findings indicate the course of anxiety and depression in women with specific risk factors. This subgroup of patients requires greater clinical attention.

EORTC QLQ-INFO26: a questionnaire to assess information given to cancer patients a preliminary analysis in eight countries.

Information disclosure is a key factor in the support for cancer patients. The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group has developed a questionnaire to evaluate the level of information received by cancer patients at different stages of their disease and treatment: the EORTC QLQ-INFO26. It can be used in clinical practice and research, including clinical trials. The questionnaire was developed following EORTC Quality of Life Group guidelines. The paper presents the data on 133 patients from eight countries. The resulting EORTC QLQ-INFO26 questionnaire includes four sub-scales on information regarding their cancer, medical tests, treatment and other services and several single items.
