Brain metastases of breast cancer

Brain metastases of breast cancer remain a difficult problem for clinical management. Their incidence appears to be increasing, which is likely due to longer survival times for advanced breast cancer patients as well as additional and improved tools for detection. Molecular features of tumors associated with this syndrome are not yet understood. In general, survival may be improving for brain metastases due to better local control in the CNS, as well as improvements in systemic disease management. Selected patients with brain metastases are able to undergo surgical resection, which has been associated with extended disease control in some patients. However, whole-brain radiation has been the mainstay for treatment for most patients. Stereotactic radiosurgery is playing an increasing role in the primary treatment of brain metastases, as well as for salvage after whole-brain radiation. Recent series have reported median survivals of 13 months or longer with stereotactic radiosurgery. Further improvements in radiation-based approaches may come from ongoing studies of radiosensitizing agents. The ability of systemic treatments to impact brain metastases has been debated, and specific treatment regimens have yet to be defined. New approaches include chemotherapy combinations, biologic therapies and novel drug-delivery strategies.

Stereotactic radiosurgery for brain tumors in pediatric patients

Brain tumors represent the most common solid tumor in children. Fractionated radiation therapy has been an important treatment modality in the multi-disciplinary management of these tumors. Stereotactic radiosurgery is the precise delivery of a single fraction of radiation and has been an important treatment option for adult brain tumor patients. Although the use of stereotactic radiosurgery in pediatric brain tumors is much less frequent, it represents an important alternative for patients with recurrent, surgically inaccessible or radioresponsive tumors. This article will review the results and logistical issues of this modality in the management of pediatric brain tumors.     

Stereotactic radiosurgery for WHO grade I meningiomas

Meningiomas represent a common intracranial tumor in the adult population. Although extirpation to achieve a gross total resection or at least decrease mass effect has been the mainstay of treatment, stereotactic radiosurgery has come to play an increasingly important role in the management of patients with meningiomas. Radiosurgery utilizes highly focused, beams of ionizing radiation to inactivate tumor cells. Image guidance and a steep dose fall off are critical features of this approach. The radiobiology of radiosurgery differs in certain advantageous ways from conventional radiotherapy. Radiosurgery initially was utilized to treat recurrent or residual skull base meningiomas. As success was observed in this setting, radiosurgery has gradually expanded its role so as to treat convexity meningiomas; it is also used as an upfront treatment for patients for whom clinical and neuro-imaging findings are consistent with a meningioma. Most large series demonstrate tumor control rates for patients with grade I meningiomas in excess of 85%. Neurological function is generally preserved or improved for patients with meningiomas. However, complications can occur. Longitudinal follow-up including neurologic and radiologic assessment is required. Single and multisession stereotactic radiosurgery will likely play an expanded role in the treatment of patients with meningiomas.     

Indications for resection and radiosurgery for brain metastases

PURPOSE OF REVIEW: This review is focused on indications for resection, stereotactic radiosurgery, and fractionated radiotherapy for patients with single or multiple brain metastases. Our purpose is to summarize the indications and effect of these management approaches. RECENT FINDINGS: Brain metastases are a frequent challenge in patients with extracranial solid cancers. More than 40% of patients with cancer will develop metastases to the brain. While some patients present with large lesions and symptoms related to mass effect, many are diagnosed when asymptomatic tumors are found on screening studies. The main options for patients with brain metastases are whole brain radiation therapy, surgical resection, and stereotactic radiosurgery. Much information regarding outcomes, survival, management morbidity, and quality of life is available. Randomized, class III clinical trials demonstrate that multimodal therapy is important for both life quality and extended survival. A better understanding of the current therapeutic options should result in improvements in patient care. SUMMARY: This is a review of the literature from May 2004 to June 2005 with special attention on publications related to effect on quality of life with different procedures and therapies.     

EANO guideline on the diagnosis and management of meningiomas

Meningiomas are the most common intracranial tumors. Yet, only few controlled clinical trials have been conducted to guide clinical decision making, resulting in variations of management approaches across countries and centers. However, recent advances in molecular genetics and clinical trial results help to refine the diagnostic and therapeutic approach to meningioma. Accordingly, the European Association of Neuro-Oncology (EANO) updated its recommendations for the diagnosis and treatment of meningiomas. A provisional diagnosis of meningioma is typically made by neuroimaging, mostly magnetic resonance imaging. Such provisional diagnoses may be made incidentally. Accordingly, a significant proportion of meningiomas, notably in patients that are asymptomatic or elderly or both, may be managed by a watch-and-scan strategy. A surgical intervention with tissue, commonly with the goal of gross total resection, is required for the definitive diagnosis according to the WHO classification. A role for molecular profiling including gene panel sequencing and genomic methylation profiling is emerging. A gross total surgical resection including the involved dura is often curative. Inoperable or recurrent tumors requiring treatment can be treated with radiosurgery, if the size or the vicinity of critical structures allows that, or with fractionated radiotherapy (RT). Treatment concepts combining surgery and radiosurgery or fractionated RT are increasingly used, although there remain controversies regard timing, type, and dosing of the various RT approaches. Radionuclide therapy targeting somatostatin receptors is an experimental approach, as are all approaches of systemic pharmacotherapy. The best albeit modest results with pharmacotherapy have been obtained with bevacizumab or multikinase inhibitors targeting vascular endothelial growth factor receptor, but no standard of care systemic treatment has been yet defined.     

Current status and optimal use of radiosurgery

The field of stereotactic radiosurgery is rapidly advancing as a result of both improvements in radiosurgical equipment and better physician understanding of the clinical applications of stereotactic radiosurgery. This article will review recent developments in the field of radiosurgery, including advances in our understanding of the treatment of brain metastases and arteriovenous malformations, as well as the use of stereotactic radiosurgery as a boost following conventional radiation for nasopharyngeal carcinoma to minimize the rate of local recurrence. In addition, improved understanding of the radiobiology of normal neurologic structures adjacent to tumors undergoing radiosurgery has led to the use of fractionated stereotactic radiosurgery for the treatment of acoustic neuromas and tumors bordering the anterior visual pathways. Finally, a breakthrough in radiosurgery involving the development and use of frameless, image-guided stereotactic radiosurgery has allowed for both dose homogeneity and treatment of intracranial lesions based on nonisocentric treatment algorithms that result in improved target conformality. This same frameless radiosurgical system has also expanded the scope of radiosurgery to include the treatment of extracranial lesions throughout the body.     

Radiotherapeutic and surgical management for newly diagnosed brain metastasis(es): An American Society for Radiation Oncology evidence-based guideline

PurposeTo systematically review the evidence for the radiotherapeutic and surgical management of patients newly diagnosed with intraparenchymal brain metastases.Methods and MaterialsKey clinical questions to be addressed in this evidence-based Guideline were identified. Fully published randomized controlled trials dealing with the management of newly diagnosed intraparenchymal brain metastases were searched systematically and reviewed. The U.S. Preventative Services Task Force levels of evidence were used to classify various options of management.ResultsThe choice of management in patients with newly diagnosed single or multiple brain metastases depends on estimated prognosis and the aims of treatment (survival, local treated lesion control, distant brain control, neurocognitive preservation).Single brain metastasis and good prognosis (expected survival 3 months or more): For a single brain metastasis larger than 3 to 4 cm and amenable to safe complete resection, whole brain radiotherapy (WBRT) and surgery (level 1) should be considered. Another alternative is surgery and radiosurgery/radiation boost to the resection cavity (level 3). For single metastasis less than 3 to 4 cm, radiosurgery alone or WBRT and radiosurgery or WBRT and surgery (all based on level 1 evidence) should be considered. Another alternative is surgery and radiosurgery or radiation boost to the resection cavity (level 3). For single brain metastasis (less than 3 to 4 cm) that is not resectable or incompletely resected, WBRT and radiosurgery, or radiosurgery alone should be considered (level 1). For nonresectable single brain metastasis (larger than 3 to 4 cm), WBRT should be considered (level 3).Multiple brain metastases and good prognosis (expected survival 3 months or more): For selected patients with multiple brain metastases (all less than 3 to 4 cm), radiosurgery alone, WBRT and radiosurgery, or WBRT alone should be considered, based on level 1 evidence. Safe resection of a brain metastasis or metastases causing significant mass effect and postoperative WBRT may also be considered (level 3).Patients with poor prognosis (expected survival less than 3 months): Patients with either single or multiple brain metastases with poor prognosis should be considered for palliative care with or without WBRT (level 3).It should be recognized, however, that there are limitations in the ability of physicians to accurately predict patient survival. Prognostic systems such as recursive partitioning analysis, and diagnosis-specific graded prognostic assessment may be helpful.ConclusionsRadiotherapeutic intervention (WBRT or radiosurgery) is associated with improved brain control. In selected patients with single brain metastasis, radiosurgery or surgery has been found to improve survival and locally treated metastasis control (compared with WBRT alone).     

CyberKnife stereotactic radiosurgery for intracranial neoplasms, with a focus on malignant tumors

Stereotactic radiosurgery is well established as a means of managing intracranial tumors, both as an adjuvant to surgical resection, and also as a primary treatment modality for those tumors that are considered unresectable by conventional surgical means. Of particular concern during radiosurgery of brain tumors is the risk of radiation damage to otherwise healthy tissue, potentially resulting in cognitive impairment. The conformality and precise targeting of the CyberKnife radiation beam enables this risk to be minimized to a greater extent than hitherto possible, which may allow treatment to be completed in a small number of fractions, thereby improving the quality of life for patients. The CyberKnife has proven particularly valuable in the treatment of metastases, which represent the great majority of brain tumors, though its role in the management of malignant glial tumors remains a subject of controversy. This article reviews the published studies on the efficacy of CyberKnife radiosurgery for brain tumors of both glial and metastatic origin, and considers its future role in the management of such lesions.     

Maintaining clarity: Review of maintenance therapy in non-small cell lung cancer

The purpose of this article is to review the role of maintenance therapy in the treatment of advanced non-small cell lung cancer (NSCLC). A brief overview about induction chemotherapy and its primary function in NSCLC is provided to address the basis of maintenance therapies foundation. The development of how maintenance therapy is utilized in this population is discussed and current guidelines for maintenance therapy are reviewed. Benefits and potential pitfalls of maintenance therapy are addressed, allowing a comprehensive review of the achieved clinical benefit that maintenance therapy may or may not have on NSCLC patient population. A review of current literature was conducted and a table is provided comparing the results of various maintenance therapy clinical trials. The table includes geographical location of each study, the number of patients enrolled, progression free survival and overall survival statistics, post-treatment regimens and if molecular testing was conducted. The role of molecular testing in relation to therapeutic treatment options for advanced NSCLC patients is discussed. A treatment algorithm clearly depicts first line and second line treatment for management of NSCLC and includes molecular testing, maintenance therapy and the role clinical trials have in treatment of NSCLC. This treatment algorithm has been specifically tailored and developed to assist clinicians in the management of advanced NSCLC.     

Traitement de la névralgie essentielle du trijumeau par radiochirurgie stéréotaxique

Idiopathic trigeminal neuralgia is defined as brief paroxysms of pain limited to the facial distribution of the trigeminal nerve. Drug therapy is considered to be the first-line of treatment for trigeminal neuralgia. Unfortunately, medical treatment does not always provide satisfactory pain relief for 25% of the patients. Moreover, the relief provided by drug therapy generally decreases over time, and increased dosages of these medications are limited because of side effects. In this case, patients can be offered several surgical approaches, such as percutaneous techniques (thermocoagulation, microcompression, glycerol injection) or microvascular decompression in the cerebello-pontine angle (Gardner-Jannetta's technique). In this indication, stereotactic radiosurgery, driven by teams using Gamma Knife^®, has shown promising efficacy and tolerance to allow this treatment being truly part of trigeminal neuralgia treatment. Technological progresses now allow performing radiosurgery with ballistic and dosimetric processes optimized with stereotactic radiosurgery dedicated linear accelerators. This procedure supports frame implantation to guarantee targeting accuracy in accordance of elevated dose distribution. This article on trigeminal neuralgia treatment will review the different medical and surgical therapeutic options and specify the contemporary place of stereotactic radiosurgery in the light of its clinical results and tolerance aspects.     

Management of brain metastases in patients with melanoma

PURPOSE OF REVIEW: Melanoma is the third most common metastatic brain tumor in the United States and is a major cause of morbidity and mortality. The development of more effective therapies for melanoma brain metastases is a major unmet clinical need and is summarized in this review. RECENT FINDINGS: Management strategies include symptomatic treatment with corticosteroids and anticonvulsants, and definitive therapy in the form of whole-brain radiation therapy, surgical resection, stereotactic radiosurgery, and systemic therapy. The data on whole-brain radiation therapy show little impact on survival, but there is evidence that it may improve neurologic deficits. Surgery may provide a survival advantage in combination with whole-brain radiation therapy in the management of a single brain melanoma metastasis, compared with whole-brain radiation therapy alone. Stereotactic radiosurgery may offer a survival advantage (in a select group of patients with limited disease) when used alone or in combination with whole-brain radiation therapy, compared with whole-brain radiation therapy alone. Fotemustine, temozolomide, and thalidomide are three agents with high central nervous system penetration that are being actively investigated as part of systemic therapy. SUMMARY: The currently available therapeutic options offer palliative relief of symptoms in most patients and a survival advantage in selected patients with melanoma and brain metastases. An urgent need exists to further define these treatments in the context of randomized trials, several of which are under way in the United States and abroad.     

Technical and clinical experience with spine radiosurgery: a new technology for management of localized spine metastases

This study is to demonstrate the technical and clinical experience of applying image guided spinal radiosurgery for treatment of localized spinal metastasis. A dedicated shaped beam radiosurgery unit with intensity modulated radiotherapy (IMRT) and x-ray based image-guided radiotherapy (IGRT) were used for the radiosurgery procedure. A total of 196 patients with 270 lesions of spinal metastases were treated with this procedure from May 2001 to October 2005. All patients received single dose radiosurgery to the involved spine only. The radiosurgery dose was escalated from 10 to 18 Gy in 2 Gy increments. The technical experience using IMRT planning and IGRT implementation has been summarized. Clinical results reporting pain relief responses have been analyzed for the first 49 patients treated with this procedure. For IMRT treatment planning, seven posterior/oblique fields were generally used for spinal radiosurgery as the optimal setup to balance conformality versus complexity. A criterion of 10 Gy to 10% of the adjacent spinal cord volume has been met with satisfactory target dose coverage for most of the cases. When the spinal cord dose exceeded this constraint, the tumor coverage was somewhat compromised. Accurate target localization has been achieved for all patients using the x-ray image-guided system. The preliminary clinical results have demonstrated that pain response was achieved in 85% of patients, with neurological improvement in patients with spinal cord compression. Patients tolerated the treatment well without major acute toxicities. Image guided spinal radiosurgery can be successfully applied to treat patients with focal spine metastases.     

The CyberKnife®

Stereotactic radiosurgery has emerged as an accepted treatment for many types of intracranial tumors. Based on the understanding of the limitations of prior radiosurgical systems, image-guided robotic radiosurgery was developed to overcome many of these restrictions. The CyberKnife® is a commercially available frameless image-guided radiosurgical system that provides state-of-the-art radiosurgery for intracranial tumors, and has also revolutionized the use of radiosurgery to treat tumors in other parts of the body. This review focuses on the current use of the CyberKnife® to treat cranial and spinal tumors. Brain metastases have long been treated with other radiosurgical systems, but the CyberKnife® allows patients with brain metastases to be treated multiple times as successive tumors are discovered, without the repetitive placement of a stereotactic head frame. Benign tumors such as acoustic neuromas, pituitary tumors, and meningiomas are also easily treated with the CyberKnife®, with radiographic tumor-control rates of >90% for pituitary tumors and 95% for acoustic neuromas and meningiomas. A subset of meningiomas and pituitary tumors surround the optic nerves and are considered to be perioptic tumors. Historically, these tumors have not been treatable with radiosurgery because of the risk of visual loss. The frameless nature of the CyberKnife® allows the radiosurgery treatment to be delivered in separate stages (typically 24 hours apart); this has been shown to significantly reduce the risk of visual loss, and thus allows effective radiosurgery treatment to be delivered. Staged radiosurgery treatment has also been used at our institution to treat acoustic neuromas, with the understanding that several stages of radiation delivery may be associated with a higher level of hearing preservation than a single-staged radiosurgery treatment. Malignant gliomas and nasopharyngeal carcinoma tumors have historically been treated with conventional radiotherapy techniques. However, we have learnt that supplementing these radiotherapy treatments with a CyberKnife® stereotactic boost after radiotherapy can improve response rates to treatment. Spinal radiosurgery is a novel development; prior frame-based radiosurgery devices did not allow treatment of lesions outside the brain and neck. We have observed high rates of tumor control when treating benign spinal tumors with the CyberKnife®, and have noted excellent pain relief and tumor-control rates in patients with spinal metastases. Future CyberKnife® stereotactic applications will focus on the continual expansion of this technology to treat tumors outside the CNS, including cancers of the lung, pancreas, liver, and prostate.     

Stereotactic Radiosurgery for Pituitary Adenomas: A Review of the Literature

OBJECTIVE: Pituitary adenomas are very common neoplasms and represent between 10 and 20% of all primary brain tumors. Historically, the treatment armamentarium for pituitary adenomas included medical management, microsurgery, and fractionated radiotherapy. More recently, radiosurgery has emerged as a viable treatment option. The goal of this research is to define accurately the efficacy, safety, and role of radiosurgery for treatment of pituitary adenomas. METHODS: Medical literature databases from 1965 to 2003 were searched for articles pertaining to pituitary adenomas and stereotactic radiosurgery. Each study was evaluated for the number of patients, radiosurgical parameters (e.g. tumor margin dose), length of follow-up, tumor growth control rate, complications, and rate of hormonal normalization in the case of functioning adenomas. RESULTS: A total of 34 published studies including 1567 patients were reviewed. Radiosurgery offers a tumor growth control rate of approximately 90%. The reported rates of hormonal normalization for functioning adenomas vary substantially. This range is in part due to widespread differences in endocrinological criteria utilized for post-radiosurgical assessment. Thus far, the risks of radiation induced neoplasia and cerebral vasculopathy associated with radiosurgery appear to be lower than for fractionated radiation therapy. The incidence of other serious complications following radiosurgery is quite low. CONCLUSIONS: Although surgical resection typically is the primary treatment modality, stereotactic radiosurgery offers safe and effective treatment for recurrent or residual pituitary adenomas. In rare instances, radiosurgery may be the best initial treatment for patients with pituitary adenomas. Refinements in the radiosurgical technique will likely lead to improved outcomes.     

Stereotactic radiosurgery:a“targeted”therapy for cancer

The developments of medicine always follow innovations in science and technology.In the past decade,such innovations have made cancer-related targeted therapies possible.In general,the term "targeted therapy" has been used in reference to cellular and molecular level oriented therapies.However,improvements in the delivery and planning of traditional radiation therapy have also provided cancer patients more options for "targeted" treatment,notably stereotactic radiosurgery(SRS) and stereotactic body radiotherapy(SBRT).In this review,the progress and controversies of SRS and SBRT are discussed to show the role of stereotactic radiation therapy in the ever evolving multidisciplinary care of cancer patients.     

Standards, options, and recommendations for radiotherapy of kidney cancer]

CONTEXT: The "Standards, Options and Recommendations" (SOR), initiated in 1993, is a collaborative project between the Federation of the French Cancer Centres (FNCLCC), the 20 French Cancer Centres and specialists from French Public Universities, General Hospitals and Private Clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary expert group, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop clinical practice guidelines for the diagnosis, management and treatment of patients with renal cancer. This review is part of previously published complete guidelines and focuses on the place of radiotherapy in this disease. METHODS: The data was identified by literature search using Medline (up to June 1999) and personal reference lists. The main endpoints considered were survival, risk factors for late effects of radiotherapy, safety and quality of life. RESULTS: The key recommendations are: 1) In localised renal cancer, adjuvant radiotherapy has a limited role: it is not indicated for T1 and T2 tumours and there is no proof of a survival benefit for T3 N1-N2 tumours. Postoperative radiotherapy can be considered in young patients without risk factors for the development of post-radiotherapy complications and without loco-regional invasion (renal capsule, renal pelvis, vena cava, regional lymph nodes); 2) For metastatic tumours, the multidisciplinary team must decide whether palliative radiotherapy is appropriate after consideration of the prognostic factors. An isolated metastasis can be treated by radiosurgery and stereotaxic radiosurgery may be of benefit in the case of one or two cerebral metastasis. The optimal dose for palliative treatment is not known. Radiotherapy followed by immunotherapy can also be considered if the patient has no contraindication to such treatments.     

CNS metastasis in primary breast cancer

The development of CNS metastasis in patients with solid malignancies represents a turning point in the disease process. The prevalence of CNS metastasis from breast cancer may be increasing due to improved systemic therapy for stage IV breast cancer. The standard treatment for multiple brain lesions remains whole-brain radiation for symptom control, with no improvement in survival. The therapy for a single brain metastasis remains either surgery or radiosurgery, with conflicting information as to the benefit of prior whole-brain radiation. The role of chemotherapy remains investigational in this setting. Leptomeningeal metastasis is conventionally treated with intrathecal chemotherapy, but may provide short-term symptom control. This review focuses on the treatment options available for both brain and leptomeningeal metastasis from breast cancer, including some investigational therapies that may be of importance in patient management in the near future.     

Long-term survivors after gamma knife radiosurgery for brain metastases

BACKGROUND: Stereotactic radiosurgery, with or without whole-brain radiation therapy, has become a valued management choice for patients with brain metastases, although their median survival remains limited. In patients who receive successful extracranial cancer care, patients who have controlled intracranial disease are living longer. The authors evaluated all brain metastasis in patients who lived for > or = 4 years after radiosurgery to determine clinical and treatment patterns potentially responsible for their outcome. METHODS: Six hundred seventy-seven patients with brain metastases underwent 781 radiosurgery procedures between 1988 and 2000. Data from the entire series were reviewed; and, if patients had > or = 4 years of survival, then they were evaluated for information on brain and extracranial treatment, symptoms, imaging responses, need for further care, and management morbidity. These long-term survivors were compared with a cohort who lived for < 3 months after radiosurgery (n = 100 patients). RESULTS: Forty-four patients (6.5%) survived for > 4 years after radiosurgery (mean, 69 mos with 16 patients still alive). The mean age at radiosurgery was 53 years (maximum age, 72 yrs), and the median Karnofsky performance score (KPS) was 90. The lung (n = 15 patients), breast (n = 9 patients), kidney (n = 7 patients), and skin (melanoma; n = 6 patients) were the most frequent primary sites. Two or more organ sites outside the brain were involved in 18 patients (41%), the primary tumor plus lymph nodes were involved in 10 patients (23%), only the primary tumor was involved in 9 patients (20%), and only brain disease was involved in 7 patients (16%), indicating that extended survival was possible even in patients with multiorgan disease. Serial imaging of 133 tumors showed that 99 tumors were smaller (74%), 22 tumors were unchanged (17%), and 12 tumors were larger (9%). Four patients had a permanent neurologic deficit after brain tumor management, and six patients underwent a resection after radiosurgery. Compared with the patients who had limited survival (< 3 mos), long-term survivors had a higher initial KPS (P = 0.01), fewer brain metastases (P = 0.04), and less extracranial disease (P < 0.00005). CONCLUSIONS: Although the expected survival of patients with brain metastases may be limited, selected patients with effective intracranial and extracranial care for malignant disease can have prolonged, good-quality survival. The extent of extracranial disease at the time of radiosurgery was predictive of outcome, but this does not necessarily mean that patients cannot live for years if treatment is effective.
