Abstract
Adjuvant radiotherapy is often necessary following surgical resection of brain metastases to improve local tumor control and survival. Brachytherapy using cesium-131 offers a novel method for loco-regional radiotherapy. We reviewed the current literature reporting the use of cesium-131 brachytherapy for the treatment of brain metastases. Published studies and ongoing trials were reviewed to identify treatment protocols and clinical outcomes of cesium-131 brachytherapy for brain metastases. Cesium-131 brachytherapy was further compared to current outcomes for iodine-125 brachytherapy and stereotactic radiosurgery. Intraoperative brachytherapy allows patients to receive two treatment modalities in one setting while minimizing tumor cell repopulation. After initial interest, the use of iodine-125 brachytherapy has declined due to unfavorable rates of radiation necrosis without survival improvement. Recent data on intracavitary cesium-131 brachytherapy in brain metastases have demonstrated improved locoregional tumor control with low risks of radiation necrosis, with associated improvements in patients compliance and satisfaction. Cesium-131 isotope has a short half-life, delivers 90% of its dose within a month, shortens the time to initiation of systemic therapy compared to iodine-125 or external radiotherapy, and has an excellent radiation safety profile. Further analyses have demonstrated superior cost-effectiveness and quality-of-life improvement ratios of cesium-131 brachytherapy than adjuvant stereotactic radiosurgery. Cesium-131 brachytherapy is a safe and effective post-surgical treatment option for brain metastases with associated clinical and cost-effectiveness benefits in appropriately selected patients.

Abstract
Background Patients with recurrent brain metastases who have exhausted external radiation options pose a treatment challenge in the setting of advances in systemic disease control which have improved quality of life and survival. Brachytherapy holds promise as salvage therapy given its ability to enforce surgical cytoreduction and minimize regional toxicity. This study investigates the role of salvage brachytherapy in maintaining local control for recurrent metastatic lesions. Methods We retrospectively reviewed our institution’s experience with brachytherapy in patients with multiply recurrent cerebral metastases who have exhausted external radiation treatment options (14 cases). The primary outcome of the study was freedom from local recurrence (FFLR). To capture the nuances of tumor biology, we compared FFLR achieved by brachytherapy to the preceding treatment for each patient. We further compared the response to brachytherapy in patients with lung cancer (8 cases) against a matched cohort of maximally radiated lung brain metastases (10 cases). Results Brachytherapy treatment conferred significantly longer FFLR compared to prior treatments (median 7.39 vs 5.51 months, P = .011) for multiply recurrent brain metastases. Compared to an independent matched cohort, brachytherapy demonstrated superior FFLR (median 8.49 vs 1.61 months, P = .004) and longer median overall survival (11.07 vs 5.93 months, P = .055), with comparable side effects. Conclusion Brachytherapy used as salvage treatment for select patients with a multiply recurrent oligometastatic brain metastasis in the setting of well-controlled systemic disease holds promise for improving local control in this challenging patient population.

Dosimetric differences between cesium-131 and iodine-125 brachytherapy for the treatment of resected brain metastases. J Contemp Brachytherapy 2020; 12:311-316. [PMID: 33293969 PMCID: PMC7690233 DOI: 10.5114/jcb.2020.98109] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2017] [Accepted: 06/29/2020] [Indexed: 11/17/2022] Open
Abstract
Purpose To compare treatment plans and evaluate dosimetric characteristics of permanent cesium-131 (131Cs) vs. iodine-125 (125I) implants used in brain brachytherapy. Material and methods Twenty-four patients with 131Cs implants from a prospective phase I/II trial were re-planned with 125I implants. In order to evaluate the volume of brain tissue exposed to radiation therapy (RT), the dose volume histogram was generated for both radioisotopes. To evaluate the dosimetric differences of the two radioisotopes we compared homogeneity (HI) and conformity indices (CI), and dose covering 100% (D100), 90% (D90), 80% (D80), and 50% (D50) of the clinical target volume (CTV). Results At the 100%, 90%, 80%, and 50% isodose lines, the 131Cs plans exposed less mean volume of brain tissue than the 125I plans (p < 0.001). The D100, D90, D80, and D50 were smaller for 131Cs (p < 0.001). The HI and CI for 131Cs vs. 125I were 19.71 vs. 29.04 and 1.31 vs. 1.92, respectively (p < 0.001). Conclusions Compared to 125I, 131Cs exposed smaller volumes of brain tissue to equivalent doses of radiation and delivered lower radiation doses to equivalent volumes of the CTV. 131Cs exhibited a higher HI, indicating increased uniformity of doses within the CTV. Lastly, 131Cs presented a CI closer to 1, indicating that the total volume receiving the prescription dose was closer to the desired CTV volume. These results suggest that 131Cs is dosimetrically superior to 125I and may explain the reason for the 0% incidence of radiation necrosis (RN) in our previously published prospective study using 131Cs.

Abstract
The advent of immunotherapy has had a major impact on the outcome and overall survival in many types of cancer. Current immunotherapeutic strategies typically aim to (re)activate anticancer T cell immunity, although the targeting of macrophage-mediated anticancer innate immunity has also emerged in recent years. Neutrophils, although comprising ≈ 60% of all white blood cells in the circulation, are still largely overlooked in this respect. Nevertheless, neutrophils have evident anticancer activity and can induce phagocytosis, trogocytosis, as well as the direct cytotoxic elimination of cancer cells. Furthermore, therapeutic tumor-targeting monoclonal antibodies trigger anticancer immune responses through all innate Fc-receptor expressing cells, including neutrophils. Indeed, the depletion of neutrophils strongly reduced the efficacy of monoclonal antibody treatment and increased tumor progression in various preclinical studies. In addition, the infusion of neutrophils in murine cancer models reduced tumor progression. However, evidence on the anticancer effects of neutrophils is fragmentary and mostly obtained in in vitro assays or murine models with reports on anticancer neutrophil activity in humans lagging behind. In this review, we aim to give an overview of the available knowledge of anticancer activity by neutrophils. Furthermore, we will describe strategies being explored for the therapeutic activation of anticancer neutrophil activity.

The role of brachytherapy in the management of brain metastases: a systematic review. J Contemp Brachytherapy 2020; 12:67-83.

Abstract
Purpose Brain metastases have a highly variable prognosis depending on the primary tumor and associated prognostic factors. Standard of care for patients with these tumors includes craniotomy, stereotactic radiosurgery (SRS), or whole brain radiotherapy (WBRT) for patients with brain metastases. Brachytherapy shows great promise as a therapy for brain metastases, but its role has not been sufficiently explored in the current literature. Material and methods The PubMed, Cochrane, and Scopus databases were searched using a combination of search terms and synonyms for brachytherapy, brain neoplasms, and brain metastases, for articles published between January 1st, 1990 and January 1st, 2018. Of the 596 articles initially identified, 37 met the inclusion criteria, of which 14 were review articles, while the remaining 23 papers with detailing individual studies were fully analyzed. Results Most data focused on 125I and suggested that it offers rates of local control and overall survival comparable to standard of care modalities such as SRS. However, radiation necrosis and regional recurrence were often high with this isotope. Studies using photon radiosurgery modality of brachytherapy have also been completed, resulting superior regional control as compared to SRS, but worse local control and higher rates of radiation necrosis than 125I. More recently, studies using the 131Cs for brachytherapy offered similar local control and survival benefits to 125I, with low rates of radiation necrosis. Conclusions For a variety of reasons including absence of physician expertise in brachytherapy, lack of published data on treatment outcomes, and rates of radiation necrosis, brachytherapy is not presently a part of standard paradigm for brain metastases. However, our review indicates brachytherapy as a modality that offers excellent local control and quality of life, and suggested that its use should be further studied.

Abstract
Brain metastases are the most common intracranial malignancies in adults. Surgical resection is the preferred treatment approach when a pathological diagnosis is required, for symptomatic patients who are refractory to steroids, and to decompress lesions causing mass effect. Radiotherapy is administered to improve local control rates after surgical resection. After a brief review of the literature describing the treatment of brain metastases using whole-brain radiotherapy, postoperative stereotactic radiosurgery, preoperative radiosurgery, and brachytherapy, we compare patient-related, technical, practical, and radiobiological considerations of each technique. Finally, we focus our discussion on intraoperative brachytherapy, with an emphasis on the technical aspects, benefits, efficacy, and outcomes of studies utilizing permanent Cs-131 implants.

Abstract
OBJECTIVE Stereotactic radiosurgery (SRS) with or without whole-brain radiotherapy can be used to achieve local control (> 90%) for small brain metastases after resection. However, many brain metastases are unsuitable for SRS because of their size or previous treatment, and whole-brain radiotherapy is associated with significant neurocognitive morbidity. The purpose of this study was to investigate the efficacy and toxicity of surgery and iodine-125 (125I) brachytherapy for brain metastases. METHODS A total of 95 consecutive patients treated for 105 brain metastases at a single institution between September 1997 and July 2013 were identified for this analysis retrospectively. Each patient underwent MRI followed by craniotomy with resection of metastasis and placement of 125I sources as permanent implants. The patients were followed with serial surveillance MRIs. The relationships among local control, overall survival, and necrosis were estimated by using the Kaplan-Meier method and compared with results of log-rank tests and multivariate regression models. RESULTS The median age at surgery was 59 years (range 29.9-81.6 years), 53% of the lesions had been treated previously, and the median preoperative metastasis volume was 13.5 cm3 (range 0.21-76.2 cm3). Gross-total resection was achieved in 81% of the cases. The median number of 125I sources implanted per cavity was 28 (range 4-93), and the median activity was 0.73 mCi (range 0.34-1.3 mCi) per source. A total of 476 brain MRIs were analyzed (median MRIs per patient 3; range 0-22). Metastasis size was the strongest predictor of cavity volume and shrinkage (p < 0.0001). Multivariable regression modeling failed to predict the likelihood of local progression or necrosis according to metastasis volume, cavity volume, or the rate of cavity remodeling regardless of source activity or previous SRS. The median clinical follow-up time in living patients was 14.4 months (range 0.02-13.6 years), and crude local control was 90%. Median overall survival extended from 2.1 months in the shortest quartile to 62.3 months in the longest quartile (p < 0.0001). The overall risk of necrosis was 15% and increased significantly for lesions with a history of previous SRS (p < 0.05). CONCLUSIONS Therapeutic options for patients with large or recurrent brain metastases are limited. Data from this study suggest that resection with permanent 125I brachytherapy is an effective strategy for achieving local control of brain metastasis. Although metastasis volume significantly influences resection cavity size and remodeling, volumetric parameters do not seem to influence local control or necrosis. With careful patient selection, this treatment regimen is associated with minimal toxicity and can result in long-term survival for some patients. ▪ CLASSIFICATION OF EVIDENCE Type of question: therapeutic; study design: retrospective case series; evidence: Class IV.

Abstract
OBJECTIVE Managing patients whose intraparenchymal brain metastases recur after radiotherapy remains a challenge. Intraoperative cesium-131 (Cs-131) brachytherapy performed at the time of neurosurgical resection may represent an excellent salvage treatment option. The authors evaluated the outcomes of this novel treatment with permanent intraoperative Cs-131 brachytherapy. METHODS Thirteen patients with 15 metastases to the brain that recurred after stereotactic radiosurgery and/or whole brain radiotherapy were treated between 2010 and 2015. Stranded Cs-131 seeds were placed as a permanent volume implant. Prescription dose was 80 Gy at 5-mm depth from the resection cavity surface. The primary end point was resection cavity freedom from progression (FFP). Resection cavity freedom from progression (FFP), regional FFP, distant FFP, median survival, overall survival (OS), and toxicity were assessed. RESULTS The median duration of follow-up after salvage treatment was 5 months (range 0.5-18 months). The patients' median age was 64 years (range 51-74 years). The median resected tumor diameter was 2.9 cm (range 1.0-5.6 cm). The median number of seeds implanted was 19 (range 10-40), with a median activity per seed of 2.25 U (range 1.98-3.01 U) and median total activity of 39.6 U (range 20.0-95.2 U). The 1-year actuarial local FFP was 83.3%. The median OS was 7 months, and 1-year OS was 24.7%. Complications included infection (3), pseudomeningocele (1), seizure (1), and asymptomatic radionecrosis (RN) (1). CONCLUSIONS After failure of prior irradiation of brain metastases, re-irradiation with intraoperative Cs-131 brachytherapy implants provides durable local control and limits the risk of RN. The authors' initial experience demonstrates that this treatment approach is well tolerated and safe for patients with previously irradiated tumors after failure of more than 1 radiotherapy regimen and that it results in excellent response rates and minimal toxicity.

Abstract
BACKGROUND Cesium-131 (Cs-131) brachytherapy is used to reduce local recurrence of resected brain metastases. In order to ensure dose homogeneity and reduce risk of radiation necrosis, inter-seed distance and cavity volume must remain stable during delivery. OBJECTIVE To investigate the efficacy of the "seeds-on-a-string" technique with intracavitary fibrin glue in achieving cavity volume stability. METHODS We placed intra-operative Cs-131 brachytherapy in 30 cavities post-resection of brain metastases. Seeds-on-a-string were placed like barrel staves within the cavity with fibrin glue. Serial MRI imaging occurred post-operatively. Pre-operative tumor volumes were compared with post-operative cavity volumes to evaluate volume stability. Thirty patients who underwent post-resective stereotactic radiosurgery (SRS) were used as a control group for volumetric comparison. RESULTS Cs-131 and SRS patients exhibited consistent cavity shrinkage over the median 110-day follow-up (p<.001), with total median shrinkage of 56.5% (Cs-131) and 84.8% (SRS). During the first month when ~88% of Cs-131 dosage is delivered, however, there was non-significant volume decrease in the Cs-131 group (median 22.0%; p=.063), while SRS patients showed significantly more shrinkage (46.7%; p=.042). No events of radiation necrosis occurred in either group. CONCLUSION Cs-131 patients exhibited significantly less cavity shrinkage than SRS patients during the first critical month with 88% Cs-131 dose delivery. This significant difference in shrinkage suggests that the intracavitary seeds-on-a-string technique facilitates increased cavity stability, promoting more homogenous dose delivery.

Abstract
OBJECT Resected brain metastases have a high rate of local recurrence without adjuvant therapy. Adjuvant whole-brain radiotherapy (WBRT) remains the standard of care with a local control rate > 90%. However, WBRT is delivered over 10-15 days, which can delay other therapy and is associated with acute and long-term toxicities. Permanent cesium-131 ((131)Cs) implants can be used at the time of metastatic resection, thereby avoiding the need for any additional therapy. The authors evaluated the safety, feasibility, and efficacy of a novel therapeutic approach with permanent (131)Cs brachytherapy at the resection for brain metastases. METHODS After institutional review board approval was obtained, 24 patients with a newly diagnosed metastasis to the brain were accrued to a prospective protocol between 2010 and 2012. There were 10 frontal, 7 parietal, 4 cerebellar, 2 occipital, and 1 temporal metastases. Histology included lung cancer (16), breast cancer (2), kidney cancer (2), melanoma (2), colon cancer (1), and cervical cancer (1). Stranded (131)Cs seeds were placed as permanent volume implants. The prescription dose was 80 Gy at a 5-mm depth from the resection cavity surface. Distant metastases were treated with stereotactic radiosurgery (SRS) or WBRT, depending on the number of lesions. The primary end point was local (resection cavity) freedom from progression (FFP). Secondary end points included regional FFP, distant FFP, median survival, overall survival (OS), and toxicity. RESULTS The median follow-up was 19.3 months (range 12.89-29.57 months). The median age was 65 years (range 45-84 years). The median size of resected tumor was 2.7 cm (range 1.5-5.5 cm), and the median volume of resected tumor was 10.31 cm(3) (range 1.77-87.11 cm(3)). The median number of seeds used was 12 (range 4-35), with a median activity of 3.82 mCi per seed (range 3.31-4.83 mCi) and total activity of 46.91 mCi (range 15.31-130.70 mCi). Local FFP was 100%. There was 1 adjacent leptomeningeal recurrence, resulting in a 1-year regional FFP of 93.8% (95% CI 63.2%-99.1%). One-year distant FFP was 48.4% (95% CI 26.3%-67.4%). Median OS was 9.9 months (95% CI 4.8 months, upper limit not estimated) and 1-year OS was 50.0% (95% CI 29.1%-67.8%). Complications included CSF leak (1), seizure (1), and infection (1). There was no radiation necrosis. CONCLUSIONS The use of postresection permanent (131)Cs brachytherapy implants resulted in no local recurrences and no radiation necrosis. This treatment was safe, well tolerated, and convenient for patients, resulting in a short radiation treatment course, high response rate, and minimal toxicity. These findings merit further study with a multicenter trial.

Abstract
Non-small-cell lung cancer (NSCLC) patients experience a high incidence of brain metastases, de novo and recurrent. We review the mechanisms of brain metastases and promising NSCLC molecular markers to delineate potential future therapeutic targets. Discussed are the current and previously utilized roles of surgery, radiation (both therapeutic and prophylactic), and systemic therapies in the treatment of NSCLC brain metastases. Future directions for treatment of NSCLC brain metastases will conclude our review.

Abstract
BACKGROUND Although brachytherapy is one of the most effective ways to treat metastatic spinal tumor with little damage to surrounding healthy tissue, it may cause radiation myelopathy if an overdose occurs. Establishing a valuable animal model can help to find a method to overcome its complications. In the current study, we set up a banna mini-pig model to mimic percutaneous vertebroplasty with 125I seed implantation. METHODS Percutaneous vertebroplasty (PVP) combined with interstitial implantation of 125I seeds, 125I seeds were transplanted into the vertebral body at the T13 level of the spine in banna mini-pigs. After raising them for up to eight months, the spinal cord and vertebral body were collected for pathological analysis. RESULTS A potential animal model had been successfully established, no case of radiation myelopathy was found in any of the treated banna pigs, and no significant cellular impairment was noted by pathological analysis. CONCLUSIONS It proves that PVP with 125I brachytherapy is an effective method to treat metastasis spinal tumor, and that the banna mini-pig can be a suitable model to investigate the mechanism of brachytherapy complications.

Abstract
BACKGROUND Use a banna mini-pig to set up 125I implantation model, and investigate the consequence of radiation-related impairments. METHODS In present study, 125I seeds were implanted into spinal canal of T13 level of spine in banna mini-pigs. After operation, the pigs were raised up to 8 months, behavior changes were recorded within this period. After 8 months, spinal cords were collected for pathological analysis. RESULTS In this study, a 125I brachytherapy animal model had been successfully established, in the model group, the banna pigs' Tarlov scale decreased from 5 to 2.57 ± 0.36, significant cellular impairments were noted by pathological analysis. CONCLUSIONS Without any protection and operation improvement, 125I implantation can cause serious histological impairments and moving difficulty for banna mini-pigs; this present research provides an alternative tool to study spinal 125I brachytherapy.

Abstract
Brachytherapy is regarded as the most effective method in the treatment of metastatic spinal tumors since little damage is caused to surrounding healthy tissue. However, this method may cause radiation myelopathy if an overdose occurs. In the present study, we established a Banna mini-pig (125)I spinal cord implantation model to provide a tool for the study of how to reduce these types of side effects. Cell cycle alteration, apoptosis and necrosis of spinal cord neurons in the presence of various doses and durations of (125)I brachytherapy were also investigated. The pigs were randomly divided into four groups, A, B, C and D. In group A, four (125)I seeds (total radioactivity, 4.0 mCi) were implanted into the dura mater of the spinal canal at the level of T13. In groups B and C, eight (125)I sources (total radioactivity, 8.0 mCi) were inserted at the same location. Groups A and C were raised for up to 8 months and group B for only 2 months. Neurons from the swine spinal cord at the T13 level were collected and cell cycle analysis was performed. Apoptosis and necrosis were tested by a terminal deoxynucleotidyl transferase dUTP nick end-labeling (TUNEL) assay. The Banna mini-pig brachytherapy model was successfully established. Radiation myelopathy was closely associated with radiation dose and duration, more neurons were blocked in the G2 and S phases as dose and time increased, and an increase in apoptosis and necrosis was detected. Ratios of apoptosis and necrosis were reduced as lower doses and shorter durations of radiation were applied. Our results demonstrate that the Banna mini-pig is an ideal animal to study (125)I brachytherapy. Low-dose and short-term brachytherapy may effectively decrease apoptosis and necrosis in spinal cord cells in Banna mini-pigs.

Abstract
Abstract
BACKGROUND:
Brain metastases represent the most common intracranial tumors and are associated with very poor prognosis.
OBJECTIVE:
To investigate the feasibility, survival, and cerebral disease control of patients with singular brain metastases treated with stereotactic 125iodine brachytherapy (SBT), to identify prognostic factors, and to compare results with other local treatment methods.
METHODS:
Complications, survival (overall and separated by recursive partitioning analysis [RPA] classes), and local and distant disease control were evaluated retrospectively in 90 patients. Prognostic factors were identified by forming subgroups of patients based on age, Karnofsky Performance Status, status of extracranial disease, interval since initial diagnosis, absence/presence of prior whole-brain radiation therapy, localization, morphology, and tumor volume.
RESULTS:
There was no treatment-related mortality, and morbidity was transient and low (3.3%). Median survival was 8.5 months overall and 18.1 months for RPA class 1 patients. After 1 year, the actuarial incidence of local and distant cerebral relapse was 5.4% and 46.4%, respectively. Karnofsky Performance Status ≥ 70 (P < .002), stable systemic disease (P < .02), RPA class 1 (P < .02), and a prolonged (> 12 month) interval between initial diagnosis and SBT (P < .05) significantly improved survival. No significant influence of previous whole-brain radiation therapy on survival or cerebral disease relapse was found.
CONCLUSION:
SBT represents a safe, minimally invasive, and, compared with SRS and microsurgery, a similarly effective local treatment option in terms of survival and cerebral disease control. It allows histological (re-)evaluation and treatment within 1 stereotactic operation. Because it is less restricted by tumor localization or size, it greatly advances local treatment options, and on the basis of its favorable biological irradiation effect, SBT does not limit additional irradiation treatment in the event of disease relapse.

Abstract
Contrary to the incidence of primary cancers, the incidence of brain metastasis has been increasing. This increase is likely because of the effects of an aging population, improved neuroimaging surveillance, and better control of systemic cancer, allowing time for brain metastasis to occur. Unlike systemic cancers, for which chemotherapy is the mainstay of treatment, the therapeutic strategies available to treat brain metastasis have traditionally been limited to surgical resection, whole brain radiation therapy, or stereotactic radiosurgery, either individually or in combination. It is important to put the treatment in the context of the prognosis for patients with brain metastases.

Abstract
INTRODUCTION Brachytherapy (BRT) is defined as a therapy technique where a radioactive source is placed a short distance from or within the tumor being treated. Much expectation has been placed on its efficacy to improve the outcome for patients with central nervous system (CNS) tumors due to the initial promising results from single institution retrospective studies. However, these optimistic findings have been highly debated since the selection criteria itself is preferable to other therapeutic modalities. The fact that BRT demonstrated no significant survival advantage in two prospective studies, together with the emerging role of stereotactic convergence therapy as a promising alternative, has further decreased the enthusiasm for BRT. Despite all the negative aspects, BRT continues to be conducted for the management of CNS tumors including gliomas, meningiomas and brain metastases. MATERIAL AND METHODS As many controversies have been aroused concerning the experience and future application of BRT, this article reviews the existing heterogeneities in terms of implants choice, optimal dose rate, targeting volume, timing of BRT, patients selection, substantial efficacy, BRT in comparison with stereotactic convergence therapy techniques and BRT in combination with other treatment modalities (data were identified by Pubmed searches). RESULTS AND CONCLUSION Though it is inconvincible to argue for the routine use of BRT, BRT may provide a choice for patients with large recurrent or inoperable deep-seated tumors, especially with the Glia-site technique. Radiotherapies including BRT may hold more promise if biologic mechanisms of radiation could be better understand and biologic modifications could be added in clinical trials.

Abstract
QUESTION What evidence is available regarding the emerging and investigational therapies for the treatment of metastatic brain tumors? TARGET POPULATION These recommendations apply to adults with brain metastases. RECOMMENDATIONS New radiation sensitizers Level 2 A subgroup analysis of a large prospective randomized controlled trial (RCT) suggested a prolongation of time to neurological progression with the early use of motexafin-gadolinium (MGd). Nonetheless this was not borne out in the overall study population and therefore an unequivocal recommendation to use the currently available radiation sensitizers, motexafin-gadolinium and efaproxiral (RSR 13) cannot be provided. Interstitial modalities There is no evidence to support the routine use of new or existing interstitial radiation, interstitial chemotherapy and or other interstitial modalities outside of approved clinical trials. New chemotherapeutic agents Level 2 Treatment of melanoma brain metastases with whole brain radiation therapy and temozolomide is reasonable based on one class II study. Level 3 Depending on individual circumstances there may be patients who benefit from the use of temozolomide or fotemustine in the therapy of their brain metastases. Molecular targeted agents Level 3 The use of epidermal growth factor receptor inhibitors may be of use in the management of brain metastases from non-small cell lung carcinoma.

Abstract
Due to improvements in diagnosis and systemic therapy, brain metastases are an increasingly common cause of morbidity and mortality for patients with advanced breast cancer. The incidence of symptomatic brain metastases among women with metastatic breast cancer ranges from 10% to 16%. The HER2 receptor, which is overexpressed in approximately 25% of all breast cancers, is an important risk factor for the development of central nervous system metastases. Surgery and radiation therapy are the primary approaches to the treatment of brain metastases but new chemotherapy and biological agents promise to play an important role in the future management of central nervous system disease. This article reviews the epidemiology, current treatment options and recent advances in the field, with a focus on HER2-positive disease and the emerging role of lapatinib for the treatment and prevention of brain metastases.

Abstract
PURPOSE To evaluate the efficacy and toxicity of surgical resection and permanent iodine-125 brachytherapy without adjuvant whole brain radiation therapy (WBRT) for brain metastases. METHODS AND MATERIALS Forty patients were treated with permanent iodine-125 brachytherapy at the time of resection of brain metastases from 1997 to 2003. Actuarial freedom from progression (FFP) and survival were measured from the date of surgery and estimated using the Kaplan-Meier method, with censoring at last imaging for FFP endpoints. RESULTS The median survival was 11.3 months overall, 12.0 months in 19 patients with newly diagnosed brain metastases and 7.3 months in 21 patients with recurrent brain metastases. Twenty-two patients (55%) remained free of progression of brain metastases, three failed at the resection cavity (including one with leptomeningeal dissemination), two failed with leptomeningeal spread only, and 13 failed elsewhere in the brain including two who also had leptomeningeal disease. The 1-year resection cavity FFP probabilities were 92%, 86% and 88%; and brain FFP probabilities were 29%, 43% and 37% for the newly diagnosed, recurrent and all patients, respectively. Symptomatic necrosis developed 7.4-40.0 months (median, 19.5 months) after brachytherapy in 9 patients (23%), confirmed by resection in 6 patients. CONCLUSIONS Excellent local control was achieved using permanent iodine-125 brachytherapy for brain metastasis resection cavities, although there is a high risk of radiation necrosis over time. These data support consideration of permanent brachytherapy without adjuvant WBRT as a treatment option in patients with symptomatic or large newly diagnosed or recurrent brain metastases.

Abstract
OBJECT Whole-brain radiotherapy (WBRT) after resection of a single brain metastasis can cause long-term radiation toxicity. The authors evaluated the efficacy of resection and placement of 125I seeds (without concomitant WBRT) for newly diagnosed single brain metastases. METHODS In a retrospective review from two institutions (1997-2003), 15 women and 11 men (mean age 55 years) with single brain metastasis underwent gross-total resection and placement of permanent low-activity 125I seeds. Primary systemic cancer sites varied. Patients were monitored clinically and radiographically. With neuroimaging evidence of local recurrence or new distant metastasis, further treatment was administered at the physician's discretion. By the median follow-up evaluation (12 months), the local tumor control rate was 96%. Distant metastases occurred in three patients within 3 months, suggesting synchronous metastasis, and in six patients more than 3 months after treatment, indicating metachronous metastasis. Treatment in these cases included radiosurgery in seven patients, WBRT in two, and resection together with 125I seed placement in one. Two patients who suffered radiation necrosis required operative intervention (lesion diameter > 3 cm, total activity > 40 mCi). All 26 patients who had been treated using resection and placement of 125I seeds had a stable or an improved Karnofsky Performance Scale score. At the last review, nine of 16 living patients showed no evidence of treatment failure. The median actuarial survival rate was 17.8 months (Kaplan-Meier method). CONCLUSIONS Permanent 125I brachytherapy applied at the initial operation without WBRT provided excellent local tumor control. Local control and patient survival rates were at least as good as those reported for resection combined with WBRT. Although the authors noted a higher incidence of distant metastases compared with that reported in other studies of initial WBRT, these metastases were generally well controlled with a combination of surgery, stereotactic radiosurgery, and, less often, WBRT. Twenty-four patients (92%) never required WBRT, thus avoiding potential long-term radiation-induced neurotoxicity.

Abstract
The development of brain metastases is often viewed as the end stage of a disease course and engenders skepticism about the efficacy of treatment. Aggressive management of brain metastases is effective in both symptom palliation and the prolongation of life. The majority of patients with controlled intracranial metastases will expire from systemic disease rather than from recurrence of these metastases. Single brain metastases should be treated with surgical resection or stereotactic radiosurgery, though it is unclear at this time if one modality is more effective than the other. Surgical resection is preferred when a pathologic diagnosis is needed, for tumors larger than 3.5 cm, or when immediate tumor mass decompression is required. Stereotactic radiosurgery (SRS) should be applied for single tumors less than 3.5 cm in surgically inaccessible areas and for patients who are not surgical candidates. Small tumors (ie, < 3.5 cm) that cause minimal edema and are surgically accessible may be treated with either surgery or SRS. There is controversy over whether whole brain radiation therapy (WBRT) can be omitted following surgical resection or SRS. Omission of WBRT increases intracranial tumor recurrence; however, this has not been correlated with decreased survival. Clinicians who choose to omit upfront WBRT are obligated to monitor the patient closely for intracranial recurrence, at which time further salvage therapy in the form of surgery, SRS, or WBRT may be considered. Histology is of particular importance when considering WBRT for patients with radioresistant tumors such as melanoma, renal cell carcinoma, or sarcoma. WBRT may be of less clinical benefit in this setting. Chemotherapy has been demonstrated to improve response rates when used as an adjunct to radiation therapy. These improvements in response rates have not been correlated with an improvement in median survival. Noncytotoxic radiosensitizing agents such as motexafin and efaproxiral show promise. Phase III trials to assess the benefit of motexafin in patients with metastatic lung cancer and efaproxiral in patients with metastatic breast cancer are ongoing. Targeted therapies offer promise in achieving therapeutic efficacy while minimizing side effects. Surgical adjuncts such as BCNU (carmustine) wafers and the GliaSite Radiation System (Cytyc Corporation, Marlborough, MA) may be useful in the future in achieving optimal local tumor control.

Abstract
OBJECT The aim of this study was to evaluate the effectiveness of brachytherapy using the GliaSite Radiation Therapy System in patients with a newly diagnosed resected single brain metastasis. The primary end point of the study was local tumor control. The secondary end points included patient survival, distant brain recurrence, quality of life, and treatment toxicity. METHODS The authors conducted a prospective multiinstitutional phase II study of GliaSite brachytherapy prescribed at a 60-Gy dose administered to a 1-cm depth after resection of a single brain metastasis. No whole-brain radiation therapy was given. Patients were assessed at 1 and 3 months after brachytherapy and every 3 months thereafter for up to 2 years. Seventy-one patients were enrolled at 13 centers. A GliaSite balloon catheter was implanted in 62 patients. Fifty-four patients received brachytherapy. The median patient age was 60 years. The most common tumor (54%) was non-small cell lung cancer. Fifty-seven percent of patients had brain metastasis only, whereas 43% had extracranial metastasis. The median final administered dose was 60 Gy. The magnetic resonance imaging--determined local control rate, based on several different methods, was 82 to 87%. Both the median patient survival time and the median duration of functional independence were 40 weeks. Among the 35 patients who died, the cause of death was neurological in 11%. Thirteen patients underwent reoperation for suspected tumor recurrence or radiation necrosis, and histological diagnoses included radiation necrosis without tumor (nine patients), radiation necrosis mixed with tumor (two patients), and tumor only (two patients). Extracranial metastasis, tumor size, and radiation necrosis were significant factors affecting patient survival. CONCLUSIONS In patients with a resected single brain metastasis, GliaSite brachytherapy leads to a local control rate, median patient survival time, and duration of functional independence similar to those achieved with resection plus whole-brain radiation therapy.

Abstract
The role for surgical treatment of brain metastases continues to evolve. Data have demonstrated survival and quality-of-life benefits for surgical treatment of appropriate lesions in selected patients. With improvements in surgical technique, along with therapeutic improvements in the management of systemic cancers, more patients are now eligible for surgical resection. Selection of patients for surgical treatment depends on performance status, size, location, and number of brain lesions, as well as the status of systemic disease. Although surgery has traditionally been performed for patients with a single brain metastasis, an increasing number of patients with multiple brain metastases may also be treated surgically. Surgical techniques, such as image guidance, intraoperative ultrasound, functional neuronavigation, cortical mapping, and awake craniotomies, have expanded the scope of lesions that can be removed safely to optimize outcomes. Seizures, peritumoral edema, and venous thromboembolic disease all contribute significantly to surgical morbidity and mortality and thus require aggressive treatment around the time of the surgical procedure to improve the quality of life and maximize survival time.

Abstract
BACKGROUND Non-small cell lung cancer is one of the leading causes of death in the developed countries. Patients die of local progression, disseminated disease or both. Brain metastases are often seen in non-small cell lung cancer patients and although they are frequently multiple, a subset of patients with a solitary brain metastasis (with controlled primary tumour) is regularly seen in clinical practice. Treatment of a solitary brain metastasis has usually been surgery, when possible, but the development of new stereotactic techniques of radiotherapy using a linear accelerator or the 'gamma knife' have provided new treatment options. OBJECTIVES To compare the effectiveness of surgery with that of radiosurgery, either combined with whole brain radiotherapy or administered alone, for patients with a solitary brain metastasis from successfully treated non-small cell lung cancer. SEARCH STRATEGY The following electronic databases were searched: the Cochrane Central Register of Controlled Trials (CENTRAL, 2004 issue 2), MEDLINE (1966 to present), EMBASE (1974 to present), CINAHL (1982 to present). Finally the Cochrane Lung Cancer Specialised Register was also searched. SELECTION CRITERIA Randomised and controlled trials that compared surgery (with or without whole brain irradiation) with all types of radiosurgery (with or without whole brain irradiation) for solitary brain metastasis from non-small cell lung cancer. All other types of studies i.e.prospective or retrospective cohort studies were not considered appropriate.Studies including patients with multiple brain metastasis or diagnosed without the support of CT scan/MRI diagnostic imaging were also excluded. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results to identify suitable trials. MAIN RESULTS Despite extensive searching no randomised trials were found. Electronic search identified 686 references. A total of 47 were selected for further evaluation but none was relevant to this review. AUTHORS' CONCLUSIONS The reviewers felt that the inclusion of studies less rigorous than randomised trials would result in misleading findings. Cohort or single arm studies only provide partial information and have the risk of significant bias. From the evaluated studies, we found that a variety of different criteria were used for the definition of solitary brain metastasis. We observed that the term "single brain metastasis" was misused as synonymous with solitary brain metastasis. Some of the single arm or cohort studies come from single institutions where the availability of both techniques (radiosurgery and surgery) is not described. Therefore, a tendency to use the most accessible technique could be suspected. Finally, in order to determine which technique is superior for patients with a solitary brain metastasis from non-small cell lung cancer, an appropriate randomised trial should be designed. Based on the available evidence a meaningful conclusion cannot be drawn.

Abstract
The authors have reviewed the results, the indications and the controversies regarding radiotherapy and chemotherapy of patients with newly diagnosed and recurrent brain metastases. Whole-brain radiotherapy, radiosurgery, hypofractionated stereotactic radiotherapy, brachytherapy and chemotherapy are the available options. New radiosensitizers and cytotoxic or cytostatic agents are being investigated. Adjuvant whole brain radiotherapy, either after surgery or radiosurgery, and prophylactic cranial irradiation in small-cell lung cancer are discussed, taking into account local control, survival, and risk of late neurotoxicity. Increasingly, the different treatments are tailored to the different prognostic subgroups, as defined by Radiation Therapy Oncology Group RPA Classes.

Abstract
The management of single brain metastases has evolved substantially over the last decade. The advent of triple-dose contrast-enhanced MRI scans has improved the radiologists' capacity to resolve small tumors, and, thereby, has resulted in a declining percentage of brain metastases classified as single. Only 25% to 30% of brain metastases are single; single brain metastases in the absence of systemic metastases are termed solitary. Randomized trials suggest that patients not in imminent danger of herniation are best managed initially with dexamethasone 2 to 4 mg administered orally twice daily. The routine use of prophylactic anticonvulsants is discouraged. Patients with refractory progressive systemic tumor likely to prove fatal within 3 to 6 months should receive fractionated whole brain radiotherapy. Patients with highly radiosensitive primary tumors such as small cell lung cancer, lymphoma, and germinoma should also receive whole brain radiotherapy. Patients with inactive or controllable systemic cancer and good performance status benefit from the addition of local strategies like surgery or radiosurgery to whole brain radiotherapy. Although surgery and radiosurgery have not been compared in a randomized controlled trial, data suggest that results are similar. Consequently, for most metastases that fall within the size constraints of radiosurgery (3.5 cm or smaller in diameter), radiosurgery is preferred for its relatively noninvasive nature. Patients with larger or cystic tumors, with obstructive hydrocephalus, or neurologic instability despite corticosteroids are best treated with craniotomy. Fractionated whole brain radiation following surgical or radiosurgical management of single brain metastasis appears to decrease the risk of recurrent brain metastasis, although it has not been shown to improve survival. We recommend its use in most patients, although patients with tumors likely to be highly resistant to fractionated radiotherapy or at high risk of radiation neurotoxicity may reasonably defer its use.
