Fatigue scores in patients with brain metastases receiving whole brain radiotherapy

The Role of Stereotactic Radiosurgery in Patients With Brain Metastases From Colorectal Cancers

BACKGROUND AND OBJECTIVES

The role of stereotactic radiosurgery (SRS) in patients with brain metastases (BMs) from colorectal cancers (CRCs) has not been established. The authors present a single-institution experience of patients with CRC who underwent SRS with metastatic brain spread.

METHODS

We retrospectively analyzed 111 patients with metastatic CRC (64 female, 57.7%), with 449 BMs treated with Gamma Knife SRS between 2000 and 2022. The median age during SRS was 63 years (range: 28-86), and the median Karnofsky Performance Scale was 80 (range: 60-100). The primary sites were colon (85 patients, 76.6%) and rectal (26 patients, 23.4%). Three patients underwent hypofractionated SRS (3 sessions) with a median margin dose of 27 Gy (range: 27-30). All other patients underwent single-session SRS with a median margin dose of 18 Gy (range: 13-20).

RESULTS

The median patient survival after SRS was 7 months (range: 1-174). Ninety-eight (88.3%) patients expired at last follow-up and 15 patients (15.3%) died related to progressive intracranial disease. A Karnofsky Performance Scale of <80 at SRS presentation ( P = .02, hazard ratio [HR]: 0.6, 95% CI: 0.4-0.9) and no previous surgical resection ( P < .01, HR: 0.4, 95% CI: 0.3-0.7) were associated with inferior overall survival using multivariate analysis. Seventeen patients (15.3%) had documented local tumor progression after SRS, at a median time of 7 months (range: 3-34) between SRS and progression. Twenty-six patients (23.4%) developed new BMs at a median of 5 months (range: 2-26) between SRS and new tumor detection. Less than three BMs at SRS presentation ( P = .02, HR: 2.6, 95% CI: 1.2-5.6) were associated with better distant tumor control on multivariate analysis. The incidence of adverse radiation effects was 5.4%.

CONCLUSION

SRS effectively controls BMs from CRC with low risk of treatment-related toxicity. During follow-up, the development of additional metastases can be safely treated by repeat SRS.

Physical Activity Attenuates Brain Irradiation-Associated Skeletal Muscle Damage in the Rat

PURPOSE

Radiation therapy for brain tumors increases patient survival. Nonetheless, side effects are increasingly reported such as cognitive deficits and fatigue. The etiology of fatigue remains poorly described. Our hypothesis is that the abscopal effects of radiation therapy on skeletal muscle may be involved in fatigue. The present study aims to assess the effect of brain irradiation on skeletal muscles and its relationship with fatigue and to analyze whether physical activity could counteract brain radiation-induced side effects.

METHODS AND MATERIALS

Adult Wistar rats were randomly distributed between 4 groups: control (CTL), irradiated (IR), nonirradiated with physical activity (PA), and irradiated with physical activity (IR+PA). IR rats were exposed to a whole-brain irradiation (WBI) of 30 Gy (3 × 10 Gy). Rats subjected to PA underwent sessions of running on a treadmill, 3 times/week for 6 months. The effects of WBI on muscles were evaluated by complementary approaches: behavioral tests (fatigue, locomotion activity), magnetic resonance imaging, and histologic analyses.

RESULTS

IR rats displayed a significant fatigue and a reduced locomotor activity at short term compared with the CTL group, which were attenuated with PA at 6 months after WBI. The IR rat's gastrocnemius mass decreased compared with CTL rats, which was reversed by physical activity at 14 days after WBI. Multiparametric magnetic resonance imaging of the skeletal muscle highlighted an alteration of the fiber organization in IR rats as demonstrated by a significant decrease of the mean diffusivity in the gastrocnemius at short term. Alteration of fibers was confirmed by histologic analyses: the number of type I fibers was decreased, whereas that of type IIa fibers was increased in IR animals but not in the IR+PA group.

CONCLUSIONS

The data show that WBI induces skeletal muscle damage, which is attenuated by PA. This muscle damage may explain, at least in part, the fatigue of patients treated with radiation therapy.

Adding simultaneous integrated boost to whole brain radiation therapy improved intracranial tumour control and minimize radiation-induced brain injury risk for the treatment of brain metastases

BACKGROUND

Brain metastases (BMs) are the most frequent intracranial tumours associated with poor clinical outcomes. Radiotherapy is essential in the treatment of these tumours, although the optimal radiation strategy remains controversial. The present study aimed to assess whether whole brain radiation therapy with a simultaneous integrated boost (WBRT + SIB) provides any therapeutic benefit over WBRT alone.

METHODS

We included and retrospectively analysed 82 patients who received WBRT + SIB and 83 who received WBRT alone between January 2012 and June 2021. Intracranial progression-free survival (PFS), local tumour control (LTC), overall survival (OS), and toxicity were compared between the groups.

RESULTS

Compared to WBRT alone, WBRT + SIB improved intracranial LTC and PFS, especially in the lung cancer subgroup. Patients with high graded prognostic assessment score or well-controlled extracranial disease receiving WBRT + SIB had improved intracranial PFS and LTC. Moreover, WBRT + SIB also improved the long-term intracranial tumour control of small cell lung cancer patients. When evaluating toxicity, we found that WBRT + SIB might slightly increase the risk of radiation-induced brain injury, and that the risk increased with increasing dosage. However, low-dose WBRT + SIB had a tolerable radiation-induced brain injury risk, which was lower than that in the high-dose group, while it was comparable to that in the WBRT group.

CONCLUSIONS

WBRT + SIB can be an efficient therapeutic option for patients with BMs, and is associated with improved intracranial LTC and PFS. Furthermore, low-dose WBRT + SIB (biologically effective dose [BED] ≤ 56 Gy) was recommended, based on the acceptable risk of radiation-induced brain injury and satisfactory tumour control.

Patient reported outcomes following whole brain radiotherapy in patients with brain metastases in NSIA-LUTH Cancer Center

BACKGROUND

Brain metastases (BM) are a common complication in advanced cancer patients, and extremely challenging to treat. Consequently, whole brain radiotherapy (WBRT) remains the standard palliative intervention for patients with BM. The present study set to evaluate the clinical benefits of WBRT by assessing the quality of life (QoL) in WBRT-treated patients with BM, in Nigeria.

METHODS

This was a prospective, longitudinal, hospital-based single-centre study. Consecutive sampling methodology was used to recruit 52 patients with BM undergoing WBRT. Patients were followed up on days 7, 30, 90 and 180 after WBRT. The EORTC QLQ-C15-PAL and EORTC QLQ-BN20 were employed to report patients' responses. The likert scale responses were linearly converted into 0 - 100 scores, and the descriptive analysis was conducted using IBM SPSS Statistics 29.0, at 95% confidence interval, using the two-tailed t-test for continuous variables or the chi-square test for categorical values. The overall survival was calculated with the Kaplan Maier method and the difference tested with Log-rank method, considering the interval from the baseline until death or end of the study.

RESULTS

The study cohort was predominantly females (82.7%), and accordingly, 65.4% of the respondents had a breast primary tumor. A goodness-of-fit test yielded non-significant Chi square Pearson (p = 0.325) and Deviance (p = 1.000) residuals, indicating the best fit. The median overall survival was 180 days (~ 6 months). A total of 20 patients (38%) that survived up to 180 days reported alleviated symptoms and better functioning. A significant improvement in physical functioning (p < 0.001) and emotional functioning (p = 0.031) was reported at 180 days post WBRT, compared to baseline.

CONCLUSIONS

WBRT is an effective palliative intervention in patients with BM, resulting in improved QoL. More than 50% of patients that survived ~ 3 months reported alleviation of pain, and 38% of patients that survived for ~ 6 months reported a significantly improved functioning. This demonstrated the clinical benefits of WBRT in palliative care and will add to the body of data on the use of WBRT, from Africa.

Multidimensional fatigue in Chinese patients with newly diagnosed meningiomas: Prevalence, severity and associated factors

OBJECTIVE

The purpose of this study was to explore the prevalence, severity, and factors associated with multidimensional fatigue in Chinese patients with newly diagnosed meningiomas.

METHODS

This cross-sectional study included 120 Chinese meningioma patients. Data were collected before surgery, including demographic, clinical, psychological, and sleep characteristics, as well as fatigue scores based on completion of the Multidimensional Fatigue Inventory (MFI-20). Mann-Whitney U tests, Kruskal-Wallis H tests, Spearman correlation and multiple linear regression were used to analyze the data.

RESULTS

The results showed there was a high prevalence of severe fatigue for each dimension: general fatigue (33.3%), physical fatigue (27.5%), reduced activity (28.3%), reduced motivation (12.5%), mental fatigue (11.7%), and total fatigue (23.3%). Headache and anxiety were found to be associated with general fatigue. Depression was related with physical fatigue. The Karnofsky Performance Status (KPS) score and depression were associated with reduced activity. Depression and the Epworth Sleepiness Scale (ESS) score were correlated with reduced motivation, while the KPS score and anxiety were associated with mental fatigue. Importantly, comorbidity, the KPS score, headache, depression, sleep disturbances, and the ESS score remained strong correlates of total fatigue.

CONCLUSIONS

Our findings indicate that newly diagnosed meningioma patients are affected by multidimensional fatigue. For patients with risk factors of fatigue, targeted interventions are advised to decrease fatigue and improve HRQoL.

Single-Session Gamma Knife Radiosurgery for Patients With 20 or More Brain Metastases

BACKGROUND

Stereotactic radiosurgery (SRS) is a widely accepted treatment modality for brain metastases. The role of SRS in patients with higher numbers of metastases remains controversial.

OBJECTIVES

To define outcomes in patients with ≥20 brain metastases managed using single-session SRS.

METHODS

This single-institution retrospective cohort study studied 75 patients (26 non-small-cell lung cancer, 21 small-cell lung cancer, 14 breast cancer, and 14 melanoma) undergoing single-session SRS. The median number of tumors per patient was 24, and the median cumulative tumor volume was 3.70 cc. The median margin dose prescribed to each individual tumor was 16 Gy. The median integral cranial dose was 5492 mJ. The median beam on time was 160 minutes. Univariate and multivariate analyses were performed with significance set at P < .05.

RESULTS

The median overall survival after SRS was 8.8 months (patients with non-small-cell lung cancer), 4.6 months (patients with small-cell lung cancer), 11.3 months (patients with breast cancer), and 4.1 months (patients with melanoma). Primary cancer type, number of brain metastases, and concurrent immunotherapy were significant factors in predicting survival. Local tumor control rate per patient was 97.3% and 94.6% at 6 and 12 months after SRS, respectively. Thirty-six patients underwent additional SRS for new tumor development with a median time after SRS of 5 months. Three patients experienced adverse radiation events.

CONCLUSION

Single-session SRS is a well-tolerated palliative treatment option even in patients with ≥20 brain metastases, achieving local control rate >90% with low risks of neurotoxicity while continuing concurrent systemic oncological care.

Brain Metastases: Patient-Reported Outcome and Quality of Life After Whole-Brain Radiotherapy

Purpose: The aim of this prospective cohort study was to determine the outcome and quality of life (QoL) for patients with brain metastases treated with whole-brain radiotherapy (WBRT). Materials and Methods: WBRT was given to 162 patients. Treatment outcome was reported through telephone consultation at four and eight weeks after the last fraction of the treatment. Treatment outcome was scored as a benefit when patients reported positively on the question whether radiotherapy of the whole brain did relieve their complaints. Patients who scored the treatment as beneficial were categorized as responders. The European Organization for Research and Treatment of Cancer (EORTC) questionnaire QLQ-C15-PAL was scored at day 0 and eight weeks after the last fraction of WBRT. Results: Patients who were alive after 2 months and reported benefit from treatment had a median survival of 8.1 months compared with 2.9 months for patients who reported no benefit. Forty-three patients died within two months (27%). Median overall survival was 3.5 months. Improvement of neurological symptoms was the most commonly reported benefit of the treatment. The responders had significantly better sleep (p = 0.032) and were less tense (p = 0.014). The nonresponders were also less tense (p = 0.042), but had less appetite (p = 0.023), felt weaker (p = 0.011), and experienced more fatigue (p = 0.001). Conclusions: WBRT is effective in a selected group of patients. Forty-nine percent of the patients surviving two months reported benefit from the treatment, resulting in a significantly increased survival rate for this group. However, 27% of patients died within two months. QoL increased in responders, but decreased in nonresponders.

Laparoscopic Gastrojejunostomy with Conversion Therapy in Gastric Outlet Obstruction Caused by Incurable Advanced Gastric Cancer

Purpose

The benefits of laparoscopic gastrojejunostomy (LGJ) combined with conversion therapy for malignant gastric outlet obstruction (GOO) caused by incurable advanced gastric cancer (AGC) are unclear. This study aimed to examine the feasibility and efficacy of LGJ followed by enteral nutrition and conversion therapy in malignant GOO.

Patients and Methods

The clinical outcomes for 66 patients with GOO due to incurable AGC were retrospectively evaluated. The patients were classified into multimodal therapy (LGJ, enteral nutrition, and chemotherapy, n = 35) and chemotherapy alone (n = 31) groups. Conversion surgery was defined as surgery aimed at R0 resection in initially incurable tumours.

Results

Compared to the chemotherapy group, multimodal therapy patients had improved oral intake, more chemotherapy cycles, better nutritional indices, less sarcopenia, and improved quality of life (QOL) post-treatment. Conversion surgery was performed in 17 multimodal therapy patients, with no perioperative mortality, and R0 resection achieved in 15 patients (88.2%). The median survival time of multimodal therapy patients was 16.7 months, compared to 4.5 months for chemotherapy patients. Multimodal therapy patients with conversion surgery had significantly longer overall survival than those without surgery (44.2 vs 8.5 months, respectively, P< 0.001). Multivariate analysis identified multimodal therapy and improved or stable QOL as independent prognostic factors.

Conclusion

Multimodal therapy was associated with better nutritional and metabolic status, a safely induced high conversion surgery rate with a high R0 resection rate, and a good prognosis. LGJ with enteral nutrition and conversion therapy may improve long-term survival in obstructive incurable AGC.

Laser interstitial thermal therapy as an adjunct therapy in brain tumors: A meta-analysis and comparison with stereotactic radiotherapy

BACKGROUND

Minimally invasive procedures are gaining widespread acceptance in difficult-to-access brain tumor treatment. Stereotactic radiosurgery (SRS) is the preferred choice, however, laser interstitial thermal therapy (LITT) has emerged as a tumor cytoreduction technique. The present meta-analysis compared current SRS therapy with LITT in brain tumors.

METHODS

A search was performed in Lilacs, PubMed, and Cochrane database. Patient's demographics, tumor location, therapy used, Karnofsky performance status score before treatment, and patient's outcome (median overall survival, progression-free survival, and adverse events) data were extracted from studies. The risk of bias was assessed by Cochrane collaboration tool.

RESULTS

Twenty-five studies were included in this meta-analysis. LITT and SRS MOS in brain metastasis patients were 12.8 months' versus 9.8 months (ranges 9.3-16.3 and 8.3-9.8; P = 0.02), respectively. In a combined comparison of adverse effects among LITT versus SRS in brain metastasis, we found 15% reduction in absolute risk difference (-0.16; 95% confidence interval P < 0.0001).

CONCLUSION

We could not state that LITT treatment is an optimal alternative therapy for difficult-to-access brain tumors due to the lack of systematic data that were reported in our pooled studies. However, our results identified a positive effect in lowering the absolute risk of adverse events compared with SRS therapy. Therefore, randomized trials are encouraged to ascertain LITT role, as upfront or postoperative/post-SRS therapy for brain tumor treatment.

Relationship between cognitive functioning, mood, and other patient factors on quality of life in metastatic brain cancer

OBJECTIVE

Neurocognitive functioning (NCF), mood disturbances, physical functioning, and social support all share a relationship with health-related quality of life (HRQOL). However, investigations into these relationships have not been conducted in persons with brain metastases (BM).

PATIENTS AND METHODS

Ninety-three newly diagnosed persons with BM were administered various cognitive batteries. Data were collected across a wide range of categories (ie, cognitive, demographic, disease/treatment, mood, social support, physical functioning). The Functional Assessment of Cancer Treatment (FACT) scale was used to measure HRQOL.

RESULTS

Mood and physical function correlated with lower HRQOL in every measured domain. Verbal learning and memory correlated with every FACT subscale except emotional quality of life. Social support also correlated with several HRQOL domains. Stepwise linear regression revealed that mood predicted general well-being and several FACT subscales, including physical, emotional and cognitive well-being. Social support and physical health were predictive of general well-being. Verbal learning and memory predicted cognitive well-being.

CONCLUSION

HRQOL is a complex construct affected by numerous variables. In particular, mood, physical functioning, and learning and memory were important predictors of HRQOL, and clinicians are encouraged to obtain information in these areas during baseline assessments in persons with BM.

Congress of Neurological Surgeons Systematic Review and Evidence-Based Guidelines on the Role of Steroids in the Treatment of Adults With Metastatic Brain Tumors

QUESTION

Do steroids improve neurological symptoms and/or quality of life in patients with metastatic brain tumors compared to supportive care only or other treatment options? If steroids are given, what dose should be used?

TARGET POPULATION

These recommendations apply to adults diagnosed with brain metastases.

RECOMMENDATIONS

STEROID THERAPY VERSUS NO STEROID THERAPYAsymptomatic brain metastases patients without mass effectInsufficient evidence exists to make a treatment recommendation for this clinical scenario.Brain metastases patients with mild symptoms related to mass effect Level 3: Corticosteroids are recommended to provide temporary symptomatic relief of symptoms related to increased intracranial pressure and edema secondary to brain metastases. It is recommended for patients who are symptomatic from metastatic disease to the brain that a starting dose of 4 to 8 mg/d of dexamethasone be considered.Brain metastases patients with moderate to severe symptoms related to mass effect Level 3: Corticosteroids are recommended to provide temporary symptomatic relief of symptoms related to increased intracranial pressure and edema secondary to brain metastases. If patients exhibit severe symptoms consistent with increased intracranial pressure, it is recommended that higher doses such as 16 mg/d or more be considered.

CHOICE OF STEROID

Level 3: If corticosteroids are given, dexamethasone is the best drug choice given the available evidence.Duration of Corticosteroid Administration Level 3: Corticosteroids, if given, should be tapered as rapidly as possible but no faster than clinically tolerated, based upon an individualized treatment regimen and a full understanding of the long-term sequelae of corticosteroid therapy.Given the very limited number of studies (2) which met the eligibility criteria for the systematic review, these are the only recommendations that can be offered based on this methodology.The full guideline can be found at https://www.cns.org/guidelines/guidelines-treatment-adults-metastatic-brain-tumors/chapter_7.

Cognitive functioning and predictors thereof in patients with 1-10 brain metastases selected for stereotactic radiosurgery

PURPOSE

Information on predictive factors of cognitive functioning in patients with (multiple) brain metastases (BM) selected for radiosurgery may allow for more individual care and may play a role in predicting cognitive outcome after radiosurgery. The aim of this study was to evaluate cognitive performance, and predictors thereof, in patients with 1-10 BM before radiosurgery.

METHODS

Cognition was measured before radiosurgery using a standardized neuropsychological test battery in patients with 1-10 BM (expected survival > 3 months; KPS ≥ 70; no prior BM treatment). Regression formulae were constructed to calculate sociodemographically corrected z scores. Group and individual cognitive functioning was analyzed. Multivariable regression was used to explore potential predictors.

RESULTS

Patients (N = 92) performed significantly worse than controls (N = 104) on all 11 test variables (medium-large effect sizes for 8 variables). Percentages of impairment were highest for information processing (55.3%), dexterity (43.2%) and cognitive flexibility (28.7%). 62% and 46% of patients had impairments in at least two, or three test variables, respectively. Models including combinations of clinical and psychological variables were predictive of verbal memory, psychomotor speed, information processing and dexterity. Neither number nor volume of metastases predicted patients' test performance.

CONCLUSIONS

Already before radiosurgery, almost half of the patients suffered from severe cognitive deficits in at least three test variables. At group and individual level, information processing, cognitive flexibility, and dexterity were most affected. These cognitive impairments may impair daily functioning and patients' ability to make (shared) treatment decisions. Both clinical (symptomatic BM; timing of BM diagnosis) and psychological (mental fatigue) characteristics influenced cognitive performance.

Brain metastases

An estimated 20% of all patients with cancer will develop brain metastases, with the majority of brain metastases occurring in those with lung, breast and colorectal cancers, melanoma or renal cell carcinoma. Brain metastases are thought to occur via seeding of circulating tumour cells into the brain microvasculature; within this unique microenvironment, tumour growth is promoted and the penetration of systemic medical therapies is limited. Development of brain metastases remains a substantial contributor to overall cancer mortality in patients with advanced-stage cancer because prognosis remains poor despite multimodal treatments and advances in systemic therapies, which include a combination of surgery, radiotherapy, chemotherapy, immunotherapy and targeted therapies. Thus, interest abounds in understanding the mechanisms that drive brain metastases so that they can be targeted with preventive therapeutic strategies and in understanding the molecular characteristics of brain metastases relative to the primary tumour so that they can inform targeted therapy selection. Increased molecular understanding of the disease will also drive continued development of novel immunotherapies and targeted therapies that have higher bioavailability beyond the blood-tumour barrier and drive advances in radiotherapies and minimally invasive surgical techniques. As these discoveries and innovations move from the realm of basic science to preclinical and clinical applications, future outcomes for patients with brain metastases are almost certain to improve.

Effect of Daily and Every Other Day Stereotactic Body Radiation Therapy Schedules on Treatment-Related Fatigue in Patients With Hepatocellular Carcinoma

PURPOSE

We compared the rate and severity of fatigue in patients who completed stereotactic body radiation therapy (SBRT) to the liver daily (QD) compared with every other day (QOD).

METHODS AND MATERIALS

From 2010 to 2017, 91 patients with Child Pugh (CP) A (n = 57) or CP-B (n = 34) cirrhosis who completed 100 SBRT sessions to 110 hepatocellular carcinoma (HCC) lesions were analyzed in this study. Confounding variables with fatigue such as CP-C cirrhosis, Eastern Cooperative Oncology Group score >2, or a history of ascites or encephalopathy were excluded. Fatigue was assessed against several treatment- and patient-related variables with univariate and propensity score-matched multivariate analysis. The median follow-up time was 18 months.

RESULTS

Patients with HCC and Barcelona-Clinic Liver Cancer stages 0 (n = 10), A (n = 32), and B (n = 58), and a median age of 62 years were analyzed. The median tumor diameter was 3 cm (1.1-11 cm). The Eastern Cooperative Oncology Group performance status score was 0 (n = 44), 1 (n = 43), or 2 (n = 13). The median dose was 45 Gy in 5 fractions, and 65 treatments were QD and 45 QOD. Grades 1 and 2 fatigue developed in 49% and 14% of treatments, respectively. Among the patients who were treated daily, 78% developed Grade 1 or 2 fatigue compared with 44% who were treated QOD (odds ratio: 4.52; P = .001). Grade 2 fatigue occurred in 22% of patients compared with 7.3% for QD and QOD treatment, respectively (odds ratio: 3.83; P = .048). There was no difference in fatigue rate for time of treatment (morning or afternoon), dose, treated volume, CP score, Barcelona-Clinic Liver Cancer stage, or performance status, which were not associated with any level of fatigue. There was no difference in local control between QD and QOD treatments.

CONCLUSIONS

Compared with traditional daily treatment fractions, SBRT that is delivered QOD to cirrhotic patients with HCC may reduce the risk of fatigue.

Survival after whole brain radiotherapy for brain metastases from lung cancer and breast cancer is poor in 6325 Dutch patients treated between 2000 and 2014

BACKGROUND

Whole brain radiotherapy (WBRT) is considered standard of care for patients with multiple brain metastases or unfit for radical treatment modalities. Recent studies raised discussion about the expected survival after WBRT. Therefore, we analysed survival after WBRT for brain metastases 'in daily practice' in a large nationwide multicentre retrospective cohort.

METHODS

Between 2000 and 2014, 6325 patients had WBRT (20 Gy in 4 Gy fractions) for brain metastases from non-small cell lung cancer (NSCLC; 4363 patients) or breast cancer (BC; 1962 patients); patients were treated in 15 out of 21 Dutch radiotherapy centres. Survival was calculated by the Kaplan-Meier method from the first day of WBRT until death as recorded in local hospital data registration or the Dutch Municipal Personal Records Database.

FINDINGS

The median survival was 2.7 months for NSCLC and 3.7 months for BC patients (p < .001). For NSCLC patients aged <50, 50-60, 60-70 and >70 years, survival was 4.0, 3.0, 2.8 and 2.1 months, respectively (p < .001). For BC patients, survival was 4.5, 3.8, 3.2 and 2.9 months, respectively (p = .047). In multivariable analyses, higher age was related to poorer survival with hazard ratios (HR) for patients aged 50-60, 60-70 and >70 years being 1.05, 1.19 and 1.34, respectively. Primary BC (HR: 0.83) and female sex (HR: 0.85) were related to better survival (p < .001).

INTERPRETATION

The survival of patients after WBRT for brain metastases from NSCLC treated in Dutch 'common radiotherapy practice' is poor, in breast cancer and younger patients it is disappointingly little better. These results are in line with the results presented in the QUARTZ trial and we advocate a much more restrictive use of WBRT. In patients with a more favourable prognosis the optimal treatment strategy remains to be determined. Prospective randomized trials and individualized prognostic models are needed to identify these patients and to tailor treatment.

Symptoms and quality of life in patients with brain metastases receiving whole-brain radiation therapy

PURPOSE

Patients with multiple brain metastases may be treated with whole-brain radiation therapy (WBRT). For these patients, symptom palliation and improvement of quality of life (QOL) and performance status is of the upmost importance. The objective of the present study was to determine the symptom experience and overall QOL in patients with brain metastases before and after WBRT.

METHODS

A total of 14 symptom scores and overall QOL were collected prospectively in 217 patients for up to 3 months. Wilcoxon signed rank test was applied to determine significant symptoms and QOL changes. Spearman's correlations were applied to determine the relationship between symptom scores and QOL.

RESULTS

Appetite loss, weakness, and nausea significantly increased from baseline, while balance, headache, and anxiety significantly decreased from baseline. At baseline, all symptoms other than coordination were significantly correlated with QOL. At 1-month follow-up (FU), changes in concentration, weakness, coordination, and balance were significantly associated with QOL changes. At 2-month FU, changes in pain, insomnia, concentration, balance, and depression were significantly associated with QOL changes. At 3-month FU, only change in nausea was significantly associated with QOL changes.

CONCLUSIONS

Following WBRT, certain symptoms may influence overall QOL to a greater extent than others, which may fluctuate with time.
