Quality of life and radiotherapy in brain metastasis patients

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.

A comparative study of whole brain radiotherapy with concomitant thalidomide versus whole brain radiotherapy alone in brain metastases

BACKGROUND

Brain metastasis increases morbidity and mortality in cancer patients. This study was undertaken to compare tumor response and treatment-related toxicities in patients treated with orally administered thalidomide concomitantly with whole brain radiotherapy to whole brain radiotherapy alone in brain metastases.

METHODS

This randomized control trial was conducted in radiation oncology department, RIMS among 42 patients of brain metastases distributed in two study arms during the period August 2018 to July 2020. Twenty patients in Arm-A received whole brain radiotherapy to a dose of 3,750 cGy in 15 fractions with concomitant oral thalidomide 200 mg daily in first week and 400 mg/day from second week of radiation onward till the end of radiotherapy, whereas 20 patients of Arm-B received whole brain radiation of 3,750 cGy in 15 fractions alone.

RESULTS

Patient characteristics were comparable. Median central nervous system progression free survival was 2 months for Arm-A and 3 months for Arm-B, whereas median overall survival study was 4 months for Arm-A and 3 months for Arm-B. Overall response rate in Arm-A was 56% and in Arm-B was 44%. Treatment-related toxicities were more in arm-A but were manageable.

CONCLUSION

Addition of thalidomide to whole brain radiotherapy makes no significant difference. Though not statistically significant, but still, Arm-A had shown some percentage benefits. Further studies with larger sample sizes should be done.

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.

Treatment Patterns, Testing Practices, and Outcomes in Patients with EGFR Mutation-Positive Advanced Non-Small-Cell Lung Cancer in Poland: A Descriptive Analysis of National, Multicenter, Real-World Data from the REFLECT Study

Non-small-cell lung cancer (NSCLC) represents 85% of new cases of lung cancer. Over the past two decades, treatment of patients with NSCLC has evolved from the empiric use of chemotherapy to more advanced targeted therapy dedicated to patients with an epidermal growth factor receptor (EGFR) mutation. The multinational REFLECT study analyzed treatment patterns, outcomes, and testing practices among patients with EGFR-mutated advanced NSCLC receiving first-line EGFR tyrosine kinase inhibitor (TKI) therapy across Europe and Israel. The aim of this study is to describe the Polish population of patients from the REFLECT study, focusing on treatment patterns and T790M mutation testing practice. A descriptive, retrospective, non-interventional, medical record-based analysis was performed on the Polish population of patients with locally advanced or metastatic NSCLC with EGFR mutations from the REFLECT study (NCT04031898). A medical chart review with data collection was conducted from May to December 2019.The study involved 110 patients. Afatinib was used as the first-line EGFR-TKI therapy in 45 (40.9%) patients, erlotinib in 41 (37.3%), and gefitinib in 24 (21.8%) patients. The first-line EGFR-TKI therapy was discontinued in 90 (81.8%) patients. The median progression-free survival (PFS) on first-line EGFR-TKI therapy was 12.9 months (95% CI 10.3-15.4). A total of 54 patients started second-line therapy, of whom osimertinib was administered to 31 (57.4%). Among 85 patients progressing on first-line EGFR-TKI therapy, 58 (68.2%) were tested for the T790M mutation. Positive results for the T790M mutation were obtained from 31 (53.4%) tested patients, all of whom received osimertinib in the next lines of therapy. The median overall survival (OS) from the start of first-line EGFR-TKI therapy was 26.2 months (95% CI 18.0-29.7). Among patients with brain metastases, the median OS from the first diagnosis of brain metastases was 15.5 months (95% CI 9.9-18.0). The results of the Polish population from the REFLECT study highlight the need for effective treatment of patients with advanced EGFR-mutated NSCLC. Nearly one-third of patients with disease progression after first-line EGFR-TKI therapy were not tested for the T790M mutation and did not have the opportunity to receive effective treatment. The presence of brain metastases was a negative prognostic factor.

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.

The Role of Stereotactic Radiosurgery in the Management of Brain Metastases From a Health-Economic Perspective: A Systematic Review

BACKGROUND

Stereotactic radiosurgery (SRS) is an effective option in the management of brain metastases, offering improved overall survival to whole-brain radiation therapy (WBRT). However, given the need for active surveillance and the possibility of repeated interventions for local/distant brain recurrences, the balance between clinical benefit and economic impact must be evaluated.

OBJECTIVE

To conduct a systematic review of health-economic analyses of SRS for brain metastases, compared with other existing intervention options, to determine the cost-effectiveness of this treatment across different clinical scenarios.

METHODS

The MEDLINE, EMBASE, Cochrane, CRD, and EconLit databases were searched for health-economic analyses, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, using terms relevant to brain metastases and radiation-based therapies. Simple cost analysis studies were excluded. Quality analysis was based on BMJ Consolidated Health Economics Reporting Standards (CHEERS) checklist.

RESULTS

Eleven eligible studies were identified. For lesions with limited mass effect, SRS was more cost-effective than surgical resection (6 studies). In patients with Karnofsky performance scale (KPS) >70 and good predicted survival, SRS was cost-effective compared to WBRT (7 studies); WBRT became cost-effective with poor performance status or low anticipated life span. Following SRS, routine magnetic resonance imaging surveillance saved $1326/patient compared to symptomatic imaging due to reduced surgical salvage and hospital stay (1 study).

CONCLUSION

Based on our findings, SRS is cost-effective in the management of brain metastases, particularly in high-functioning patients with longer expected survival. However, before an optimal care pathway can be proposed, emerging factors such as tumor molecular subtype, diagnosis-specific graded prognostic assessment, neuroprognostic score, tailored surveillance imaging, and patient utilities need to be studied in greater detail.

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.

Survival and quality of life after whole brain radiotherapy with 3D conformal boost in the treatment of brain metastases

Background

Brain metastases are the most frequent intracranial neoplasms in adults. Although overall survival (OS) is an important endpoint in patients receiving radiotherapy, given their poor life expectancy in general, quality of life is becoming an increasingly useful endpoint. Objectives: to evaluate whole brain radiotherapy (WBRT) with 3D conformal boost in brain metastases patients with regard to OS and quality of life.

Methods

During April 2015-May 2017, a total of 35 patients with ≤5, previously untreated, inoperable brain metastases were included prospectively. All patients underwent WBRT followed by 3D conformal boost to the metastatic lesions. EORTC quality of life questionnaires QLQ-C30 and QLQ-BN20 were used at baseline and at end of treatment. The mean initial and final scores were compared using Student test. One-year OS with brain metastases was computed with Kaplan Maier method.

Results

Median survival with brain metastases was 4.43 months (0.73-78.53). The one-year OS for patients with one metastasis was 42% versus 15% for more than one (p<0.04). The presence of extracerebral metastases significantly decreased OS from 39% without extracerebral metastases to 19%. (p<0.05). Quality of life improved significantly in several functional domains: physical (48 vs 60.29), role functioning (28.1 vs 44.7), emotional (47.1 vs 80.2), global health status (40.9 vs 62.3). Symptom scores decreased significantly in most items, corresponding to an improvement in the symptom burden: headache (61.9 vs 0.9), nausea and vomiting (45.7 vs 7.1), visual disorder (26.3 vs 9.2), seizures (30.4 vs 0.9), motor dysfunction (46.6 vs 17.1). Symptom scores for fatigue and drowsiness increased significantly (51.1 vs 74.9, respectively 37.1 vs 70.4), indicating worsening of symptoms.

Conclusions

WBRT with 3D conformal boost is a feasible technique which improves quality of life in brain metastases patients. Since survival is limited, the assessment of quality of life is a good indicator of the treatment outcome.

Combination of anti-PD-1 therapy and stereotactic radiosurgery for a gastric cancer patient with brain metastasis: a case report

Background

Brain metastases from gastric cancer are difficult to treat and their prognosis is poor. Despite various possible treatments, the survival rate of such patients is still unsatisfactory; therefore, new treatment modalities or combinations of therapies need to be explored.

Case presentation

We herein discuss a case of a 38-year-old man initially diagnosed with a gastric cancer brain metastasis. At first, only stereotactic radiosurgery (SRS) was performed, but it was not effective. After the brain and systemic metastases progressed, SRS and anti-PD-1 therapy were administered in combination, and the brain and intra-abdominal metastatic lesions responded satisfactorily.

Conclusion

The combination of anti-PD-1 therapy and SRS could be effective against gastric cancer with brain metastases.

Nested Cohort Study to Identify Characteristics That Predict Near-Term Disablement From Lung Cancer Brain Metastases

OBJECTIVE

To test whether the presence of patient- and imaging-level characteristics (1) are associated with clinically meaningful changes in mobility among patients with late-stage cancer with metastatic brain involvement, and (2) can predict their risk of near-term functional decline.

DESIGN

Prospective nested cohort study.

SETTING

Quaternary academic medical center.

PARTICIPANTS

The study population consisted of a nested cohort of the patients with imaging-confirmed brain metastases (n=66) among a larger cohort of patients with late-stage lung cancer (N=311).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Functional evaluations with the Activity Measure for Post-Acute Care Computer Adaptive Test (AM-PAC-CAT) and symptom intensity ratings were collected at monthly intervals for up to 2 years.

RESULTS

In exploratory univariate models, whole brain radiation therapy (WBRT) and imaging findings of cerebellar or brainstem involvement were associated with large AM-PAC-CAT score declines reflecting worsening mobility (-4.55, SE 1.12; -2.87, SE, 1.0; and -3.14, SE 1.47, respectively). Also in univariate models, participants with new neurologic signs or symptoms at imaging (-2.48; SE .99), new brain metastases (-2.14, SE .99), or new and expanding metastases (-2.64, SE 1.14) declined significantly. Multivariate exploratory mixed logistic models, including WBRT, cerebellar/brainstem location, presence of new and expanding metastases, and worst pain intensity, had excellent predictive capabilities for AM-PAC-CAT score declines of 7.5 and 10 points (C statistics ≥0.8).

CONCLUSIONS

Among patients with lung cancer and brain metastases, cerebellar/brainstem location, new and expanding metastases, and treatment with WBRT may predict severe, near-term mobility losses and indicate a need to consider rehabilitation services.

On the cutting edge of intensity modulated radiotherapy and simultaneous integrated boost (IMRT-SIB): The case of a patient with 8 brain metastases

BACKGROUND

Patients with multiple brain metastases, especially those with more than 3 lesions, usually undergo to palliative whole brain (WB) radiotherapy (RT).

METHODS

A breast cancer patient with 8 brain metastases was treated on the brain by a radical RT regimen. Prescription doses were according to the simultaneous integrated boost-intensity modulated radiation therapy (SIB-IMRT) technique with all lesions as well brain irradiated simultaneously in 20 daily fractions. Doses of 40.0 Gy (2.0 Gy/fraction) and 50.0 Gy (2.5 Gy/fraction) were prescribed to the whole brain and to eight individual metastases, respectively.

RESULTS

Mean volume of the eight metastases was 8.1 cc (range: 3.8-10.1 cc). For all lesions, the volume receiving 95% of prescribed dose was 100% and dose homogeneity was within 3%. Moreover, maximum doses were less than 105% of prescribed dose, while average mean dose to lesions was 50.6 Gy (range: 49.7-51.5 Gy). Whole brain mean dose was 45.2 Gy. Maximum doses to brainstem and optic chiasma were limited to 44.5 Gy and 42.9 Gy, respectively, while maximum doses to eyes, lens and optic nerves were limited to 9.2 Gy, 4.9 Gy and 41.0 Gy, respectively. From a clinical point of view, subsequent MRI brain controls showed a complete clinical response. Forty months after treatment the patient is disease free and shows no late brain and skin toxicities.

CONCLUSION

This case demonstrates the technical feasibility of a SIB-IMRT treatment in patients with more than 3 brain metastases.

Palliative whole-brain radiotherapy and health- related quality of life for patients with brain metastasis in cancer

OBJECTIVE

To assess the use of palliative whole-brain radiotherapy (WBRT) in the treatment of brain metastases (BMs) and to evaluate the health-related quality of life (HRQOL) of these patients.

MATERIALS AND METHODS

We conducted a retrospective study of 46 patients with BMs who were treated with WBRT at the First Affiliated Hospital of Xi'an Jiaotong University between January 2013 and January 2015. External beam radiotherapy techniques were used to deliver 40 Gy in 20 fractions or 30 Gy in ten fractions with a 10 MV photon beam from a linear accelerator to the whole brain. Data were stored and analyzed using SPSS version 17.0.

RESULTS

Of the 46 patients, the survival time of patients in our study was 10.8±0.55 months: 11.8±0.46 months in patients with WBRT, 11.75±1.00 in patients with WBRT + chemotherapy, and 3±0.79 months in patients with supportive care, respectively (P<0.01). The HRQOL scores of all the patients were 70±1.16 (before therapy) and 76.83±1.04 (after therapy) (P<0.01). The HRQOL scores of the patients with WBRT were 72.23±0.88 (before therapy) and 78.49±0.87 (after therapy) (P<0.01). There was no central nervous system toxicity; only two (4.3%) patients were found to have BM hemorrhage. Radiation necrosis happened in one patient (2.2%).

CONCLUSION

Effective treatment options for patients with BMs are important. WBRT was evaluated to ensure survival outcomes and QOL were enhanced after therapy for patients with BMs.

Brain metastases from stomach cancer - The role of different treatment modalities and efficacy of palliative radiotherapy

AIM

To evaluate different treatment modalities, sequences, and prognostic factors in patients with brain metastases from stomach cancer.

BACKGROUND

Brain metastases from gastric cancer are rare and late manifestation of the disease, occurring in less than 1% of gastric cancer patients. The prognosis is poor and median overall survival is 1.3-2.4 months. The standard treatment scheme has not yet been described. Most studies present small sample sizes. The choice of treatment scheme is individually based on performance status, number, location and size of metastases, the status of primary tumor and the presence of other metastases.

MATERIALS AND METHODS

Sixteen patients diagnosed with brain metastases from gastric cancer in Maria Sklodowska-Curie Memorial Cancer Center and Institute of Oncology, Gliwice Branch. Patients, mostly men (69%) aged 51-75 years, (median 68.5 years). Thirteen (81.25%) had treatment of primary tumor before diagnosis of brain metastases. Primary metastatic gastric cancer was diagnosed in 6 patients (37.5%), in 3 cases (18.75%) brain was the site of those metastases. Treatment schemes were individually based.

RESULTS

We identified prognostic factors influencing OS: performance status, number of brain metastases, type of treatment. Median OS was 2.8 months. Median time to brain metastases was 12.3 months and it was shorter in patients with pretreatment metastases to other organs. Patients treated with combined treatment had median survival of 12.3 months.

CONCLUSIONS

Aggressive treatment schemes are needed to improve the outcome. Prognostic factors such as performance status, number of metastases, dissemination to other organs are helpful in considering the best treatment options.

Incidence of hospitalization in patients receiving short course palliative cranial radiotherapy on outpatient basis in a limited resource setting - Experience from a regional cancer center in India

AIM

To investigate incidence of toxicity and related hospitalization among patients treated at our institute by a short course of palliative cranial radiotherapy against a longer, widely established schedule.

BACKGROUND

Shorter schedule palliative cranial radiotherapy is more convenient for patients and reduce waiting times. Although many studies have established safety of short schedules, the need for hospitalization due to acute treatment toxicity remains under-explored. Hospital admissions are an economic burden both for the patient and healthcare system in a limited resource setting. Delivery of treatment on an outpatient basis and within shorter times is preferred by patients, caregivers and healthcare staff.

MATERIALS AND METHODS

This was a prospective study on 68 patients treated with palliative whole brain radiotherapy between November 2010 and October 2012. One group received 20 Gy in 5 fractions over 1 week and the other group, 30 Gy in 10 fractions over 2 weeks. Treatment toxicity due to cranial radiotherapy was assessed as per RTOG acute and late toxicity criteria. Need for hospitalization owing to acute toxicity was also noted. Significant differences in the study parameters between the two groups were calculated by Fisher's t-test.

RESULTS

Requirement for hospital stay due to acute toxicity was not significantly different between the two groups. Patients in both groups experienced similar toxicity both during and after treatment.

CONCLUSIONS

The shorter course entailed no significant increase in toxicity related admissions, suitable for limited resource settings where patient transport is difficult, there are financial constraints, and the healthcare system is overburdened.

Evaluation of results of linac-based radiosurgery for brain metastases from primary lung cancer

AIM

The purpose of our review was to evaluate results of radiosurgery for patients with brain metastases from lung cancer.

BACKGROUND

Lung cancer is the leading cause of death from cancer and the most common source of brain metastases. Radiosurgery allows the precise focal delivery of a high single radiation dose to brain metastases and results in high rates of local control.

MATERIALS AND METHODS

83 patients were treated between 2006 and 2008. We evaluated local control and outcome after radiosurgery and identified prognostic factors.

RESULTS

Median survival in the whole group was 7.8 months from radiosurgery and 11 months from diagnosis. Median survival in classes I, II and III was 13.2, 8.2 and 2.2 months. For 94% of patients symptoms improved or stabilised at the first follow-up visit and this status did not change during 7.1 months. According to the univariate analysis, factors associated with improved survival included: RPA class 1 compared with RPA 2 and 3, RPA class 2 compared with RPA 3, KPS > 70, control of the primary disease, radiosurgery performed more than once, level of haemoglobin >7 mmol/1, absence of extracranial metastases, volume of the biggest lesion <11 cm(3). The multivariate analysis confirmed a significant influence on survival for the following factors: RPA class 1 as compared with RPA 3, KPS > 70, absence of extracranial metastases, multiplicity of radiosurgery.

CONCLUSIONS

Stereotactic radiosurgery is a safe and effective treatment. It proved to be effective and safe in older patients. Selection of patients who are likely to benefit most should be based on prognostic factors. KPS proved to be the most important prognostic factor. In the RPA III group (patients with KPS < 70) survival time was similar to that achieved after symptomatic medical management.

Whole brain radiotherapy: Consequences for personalized medicine

Several studies focusing on brain irradiation are in progress. Reflecting updates of relevant outcomes in palliative treatment of patients suffering from brain metastases, the primary objective of these studies is the evaluation of neurocognitive function and quality of life. Improvements of technology in radiation oncology allows us to spare the hippocampal region while appropriately irradiating other parts of brain tissue. Irradiation of the hippocampus region is likely to lead to manifestations of adverse events with a subsequent impact on patient's quality of life, which is in fact an improper approach in palliative medicine. Ongoing studies evaluate results of hippocampus avoiding radiotherapy compared to standard whole brain radiotherapy. Incorporation of neurocognitive function assessment may result in the confirmation of superiority of sparing the region of hippocampus and thus change current style of providing brain irradiation.
