Laser interstitial thermal therapy (LITT) for intracranial lesions: a single-institutional series, outcomes, and review of the literature. Br J Neurosurg 2024; 38:632-638. [PMID: 34240676 DOI: 10.1080/02688697.2021.1947972] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2020] [Revised: 06/15/2021] [Accepted: 06/22/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION Laser interstitial thermal therapy (LITT) is a minimally invasive treatment method in managing primary brain neoplasms, brain metastases, radiation necrosis, and epileptogenic lesions, many of which are located in operative corridors that would be difficult to address. Although the use of lasers is not a new concept in neurosurgery, advances in technology have enabled surgeons to perform laser treatment with the aid of real-time MRI thermography as a guide. In this report, we present our institutional series and outcomes of patients treated with LITT. METHODS We retrospectively evaluated 19 patients (age range, 28-77 years) who underwent LITT at one or more targets from 2015 to 2019. Primary endpoint observed was mean progression free survival (PFS) and overall survival (OS). RESULTS Seven patients with glial neoplasms and 12 patients with metastatic disease were reviewed. Average hospitalization was 2.4 days. Median PFS was 7 and 4 months in the metastatic group and primary glial neoplasm group, respectively (p = 0.01). Median OS from time of diagnosis was 41 and 32 months (p = 0.02) and median OS after LITT therapy was 25 and 24 months (p = 0.02) for the metastatic and primary glial neoplasm groups, respectively. One patient experienced immediate post-procedural morbidity secondary to increased intracerebral edema peri-lesionally while one patient experienced post-operative mortality and expired secondary to hemorrhage 1-month post-procedure. Median follow-up was 10 months. CONCLUSION Laser interstitial thermal therapy (LITT) is a safe, minimally invasive treatment method that provides surgeons with cytoreductive techniques to treat neurosurgical conditions. Both PFS and OS appear to be more favorable after LITT in patients with metastatic disease. In properly selected patients, this modality offers improved survival outcomes in conjunction with other salvage therapies.

Abstract
Postsurgical radiotherapy (RT) has been early proven to prevent local tumor recurrence, initially performed with whole brain RT (WBRT). Subsequent to disadvantageous cognitive sequalae for the patient and the broad distribution of modern linear accelerators, focal irradiation of the tumor has omitted WBRT in most cases. In many studies, the effectiveness of local RT of the resection cavity, either as single-fraction stereotactic radiosurgery (SRS) or hypo-fractionated stereotactic RT (hFSRT), has been demonstrated to be effective and safe. However, whereas prospective high-level incidence is still lacking on which dose and fractionation scheme is the best choice for the patient, further ablative techniques have come into play. Neoadjuvant SRS (N-SRS) prior to resection combines straightforward target delineation with an accelerated post-surgical phase, allowing an earlier start of systemic treatment or rehabilitation as indicated. In addition, low-energy intraoperative RT (IORT) on the surgical bed has been introduced as another alternative to external beam RT, offering sterilization of the cavity surface with steep dose gradients towards the healthy brain. This consensus paper summarizes current local treatment strategies for resectable brain metastases regarding available data and patient-centered decision-making.

Low-Energy X-Ray Intraoperative Radiation Therapy (Lex-IORT) for Resected Brain Metastases: A Single-Institution Experience. Cancers (Basel) 2022; 15:cancers15010014. [PMID: 36612015 PMCID: PMC9817795 DOI: 10.3390/cancers15010014] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Resection followed by local radiation therapy (RT) is the standard of care for symptomatic brain metastases. However, the optimal technique, fractionation scheme and dose are still being debated. Lately, low-energy X-ray intraoperative RT (lex-IORT) has been of increasing interest. METHOD Eighteen consecutive patients undergoing BM resection followed by immediate lex-IORT with 16-30 Gy applied to the spherical applicator were retrospectively analyzed. Demographic, RT-specific, radiographic and clinical data were reviewed to evaluate the effectiveness and safety of IORT for BM. Descriptive statistics and Kaplan-Meyer analysis were applied. RESULTS The mean follow-up time was 10.8 months (range, 0-39 months). The estimated local control (LC), distant brain control (DBC) and overall survival (OS) at 12 months post IORT were 92.9% (95%-CI 79.3-100%), 71.4% (95%-CI 50.2-92.6%) and 58.0% (95%-CI 34.1-81.9%), respectively. Two patients developed radiation necrosis (11.1%) and wound infection (CTCAE grade III); both had additional adjuvant treatment after IORT. For five patients (27.8%), the time to the start or continuation of systemic treatment was ≤15 days and hence shorter than wound healing and adjuvant RT would have required. CONCLUSION In accordance with previous series, this study demonstrates the effectiveness and safety of IORT in the management of brain metastases despite the small cohort and the retrospective characteristic of this analysis.

Abstract
Brain metastases represent the most common intracranial neoplasm and pose a significant disease burden on the individual and the healthcare system. Although whole brain radiation therapy was historically a first line approach, subsequent research and technological advancements have resulted in a larger armamentarium of strategies for treatment of these patients. While chemotherapeutic options remain limited, surgical resection and stereotactic radiosurgery, as well as their combination therapies, have shifted the paradigms for managing intracranial metastatic disease. Ultimately, no single treatment is shown to be consistently effective across patient groups in terms of overall survival, local and distant control, neurocognitive function, and performance status. However, close consideration of patient and tumor characteristics may help delineate more favorable treatment strategies for individual patients. Here the authors present a review of the recent literature surrounding surgery, whole brain radiation therapy, stereotactic radiosurgery, and combination approaches.

Abstract
Historical theories of metastasis have been informed by the seed and soil hypothesis, the Halsteadian paradigm proposing an orderly spread from local to distant sites, and the presumption that cancer is an inherently systemic process even in the earliest cases. The more contemporary spectrum theory now suggests that the propensity for distant spread exists along a continuum of metastatic virulence. Tumors with limited metastatic potential represent one subset along this spectrum that could potentially be cured with local ablative therapy. Integrating clinical and molecular features to biologically inform the classification of not only oligometastatic or oligoprogressive disease but also the entire metastatic spectrum holds great promise to improve prognostication and inform clinical decision making. To this end, the inclusion of molecular correlative studies and biospecimen collection on prospective protocols is imperative.

Abstract
BACKGROUND/AIM Seizures can be the initial symptom of brain metastases. This study investigated pre-treatment seizures in patients with a single lesion. PATIENTS AND METHODS Pre-operative seizures were analyzed in 104 patients with a single brain metastasis receiving resection plus whole-brain irradiation and a boost. Prevalence of seizures, risk factors and associations with survival (OS) were evaluated. RESULTS Thirty patients (34.6%) had seizures prior to neurosurgery. Significant associations between seizures and investigated characteristics were not found. However, age ≤61 years showed a trend (p=0.117) for increased incidence of seizures. Time from diagnosis of malignancy until neurosurgery >12 months was significantly associated with improved OS on univariate analysis (p=0.003). Trends for a positive association with OS were found for no seizures (p=0.054), female gender (p=0.066) and breast cancer (p=0.098). On multivariate analysis, time until neurosurgery >12 months was independently associated (p=0.019) with better OS, and seizures showed a trend (p=0.119) for improved OS. CONCLUSIONS Considering the high prevalence of seizures in this cohort, regular screening and monitoring of these patients appears reasonable. This applies particularly to patients aged ≤61 years.

Abstract
BACKGROUND/AIM Elderly patients with a single brain metastasis likely benefit from personalized treatment protocols. To add to treatment personalization, a survival score was generated for these patients. PATIENTS AND METHODS This retrospective study included 36 elderly patients, each with a single brain metastasis, who received surgery followed by whole-brain irradiation and a radiation boost. Six pre-treatment characteristics were evaluated regarding survival, namely age, gender, Karnofsky performance score (KPS), type of primary tumor, non-cerebral metastasis and interval from diagnosis of the neoplasm until surgery. RESULTS When applying the Cox regression model, KPS (p=0.005) and tumor type (p=0.018) were significant and incorporated in the score. Based on 12-month survival probabilities, three groups of 6-9 (n=5), 10-11 (n=15) and 14-19 points (n=16) were formed, with 12-month survival rates of 0%, 33% and 100%, respectively (p<0.0001). CONCLUSION A survival score was generated specifically for elderly patients with a single brain metastasis that can improve personalization of their treatment.

Abstract
OBJECTIVES For patients who develop brain metastases from solid tumors, age, KPS, primary tumor status and presence of extracranial metastases have been identified as prognostic factors. However, the factors that affect survival in patients who are deemed fit to undergo resection of brain metastases have not been clearly elucidated hitherto. PATIENTS AND METHODS This is a retrospective analysis of a prospectively maintained database. All patients who underwent resection of intracranial metastases from solid tumors were included. Various patient, disease and treatment related factors were analyzed to assess their impact on survival. RESULTS Overall, 124 patients had undergone surgery for brain metastases from various primary sites. The median age and pre-operative performance score were 53 years and 80 respectively. Synchronous metastases were resected in 17.7% of the patients. The postoperative morbidity and mortality rates were 17.7% and 2.4% respectively. Adjuvant whole brain radiation was received by 64 patients. At last follow-up, 8.1% of patients had fresh post-surgical neurologic deficits. The median progression free and overall survival were 6.91 was 8.56 months respectively. CONCLUSIONS Surgical resection of for brain metastases should be considered in carefully selected patients. Gross total resection and receiving adjuvant whole brain RT significantly improves survival in these patients.

Abstract
Stereotactic treatments are today the reference techniques for the irradiation of brain metastases in radiotherapy. The dose per fraction is very high, and delivered in small volumes (diameter <1 cm). As part of these treatments, effective detection and precise segmentation of lesions are imperative. Many methods based on deep-learning approaches have been developed for the automatic segmentation of gliomas, but very little for that of brain metastases. We adapted an existing 3D convolutional neural network (DeepMedic) to detect and segment brain metastases on MRI. At first, we sought to adapt the network parameters to brain metastases. We then explored the single or combined use of different MRI modalities, by evaluating network performance in terms of detection and segmentation. We also studied the interest of increasing the database with virtual patients or of using an additional database in which the active parts of the metastases are separated from the necrotic parts. Our results indicated that a deep network approach is promising for the detection and the segmentation of brain metastases on multimodal MRI.

Abstract
Aims and Background Late brain metastases from breast cancer are a rare event. Only a few cases have been reported in the English literature. The authors describe the clinical and pathological remarks, together with treatment modalities, removal extent and overall survival, of 11 patients in whom brain metastases were detected more than 10 years from the primary tumor. Patients and Methods Between January 1997 and April 2001, we hospitalized 11 patients, all females, with a histologically proven diagnosis of brain metastasis from breast invasive ductal carcinoma. We defined ‘late metastasis’ as those metastases that appeared at least 10 years after the breast cancer diagnosis. The median age at the moment of brain metastasis diagnosis was 59 years (range, 47-70), with a median latency time from breast cancer diagnosis of 16 years (range, 11-30). Results Ten patients underwent surgery followed by adjuvant radiotherapy (whole brain radiotherapy). Two of them received, after whole brain radiotherapy, stereotaxic radio surgery treatment. One patient had stereotaxic brain biopsy, performed by neuronavigator, followed by palliative corticosteroid therapy. Median survival after brain metastasis diagnosis was 28 months (range, 3 months-4 years). Conclusions Although late brain metastases are a rare event, specific neurologic symptoms and neuroradiological evidence of a cerebral neoplasm should be correlated to the presence of a cerebral metastasis, in a patient with a previous history of breast cancer. The longer latency time from breast cancer to brain metastasis could be explained by the “clonal dominance” theory and by different genetic alterations of the metastatic cell, which could influence the clinical history of the disease.

Stereotactic fractionated radiotherapy of the resection cavity in patients with one to three brain metastases. Clin Neurol Neurosurg 2016; 142:81-86. [PMID: 26816106 DOI: 10.1016/j.clineuro.2016.01.008] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2015] [Revised: 11/05/2015] [Accepted: 01/05/2016] [Indexed: 11/23/2022]
Abstract
OBJECTIVES The goal of this study is to evaluate the role of stereotactic fractionated radiotherapy (SFRT) in patients with one to three brain metastases after surgical resection. METHODS AND MATERIALS We performed a retrospective single-institutional study in patients undergoing SFRT of surgical cavity after resection of ≤3 brain metastases. 60 patients with newly diagnosed brain metastases treated with SFRT following resection were included. The total irradiation dose was 30 Gy (5 Gy/d, BED 45 Gy) after complete macroscopical resection and 35 Gy (5 Gy/d, BED 52.5 Gy) in patients with macroscopic residual tumour after surgery. Macroscopic residual tumour was defined as contrast enhancement next to the resection cavity on the postoperative T1-MRI. The gross tumour volume (GTV) encompassing the residual tumour was delineated on the T1-MRI, the clinical target volume (CTV) encompassed the surgical cavity plus 1mm and the planning target volume (PTV) the CTV plus 2mm. RESULTS Eight of 60 patients had no imaging follow-up due to morbidity/mortality. Two of 52 (3.8%) patients experienced local failures only, 25 of 52 (48.1%) patients experienced distant intracranial failures only and 4 (7.7%) patients experienced both local and distant intracranial failures. In summary, there were 6 (11.5%) local failures and 29 (55.8%) distant failures. Age was significant for local control in the Cox regression test (p=0.046). Thirty-seven of 60 (61.7%) patients died during follow-up. Median follow-up was 8 months. Median overall survival was 15 months. Cox regression for survival was significant for KPS score ≤70% and size of PTV. No severe side effects were seen. Patients undergoing whole brain radiation therapy (WBRT) as salvage therapy in case of progression had no severe side effects either. CONCLUSION In the light of encouraging local control rates, SFRT could be an alternative to WBRT after surgical resection of ≤3 brain metastases. Due to the high rate of distant intracranial failure regular follow-up with MRI is mandatory.

Abstract
The introduction of small molecule BRAFV600 kinase inhibitors represents a milestone in the targeted therapy of patients with metastatic melanoma by a significant increase in therapeutic efficacy in terms of overall and progression-free survival compared with conventional chemotherapy. Beside BRAFV600 inhibitor treatment, radiotherapy is a further mainstay for the therapy of metastatic melanoma and thus a concomitant or sequential application of BRAFV600 inhibitors and radiotherapy is inevitable. Recent reports show a significant radiosensitization of the irradiated healthy tissue in patients with melanoma after the combination of radiotherapy and BRAFV600 inhibitors, evoking concern in clinical practice. We review interactions of BRAFV600 inhibitors and radiation with regard to antitumor effects and an increased radiotoxicity in the healthy tissue.

Abstract
BACKGROUND Surgery followed by adjuvant radiotherapy is a well-established treatment paradigm for brain metastases. OBJECTIVE To examine the effect of postsurgical whole-brain radiotherapy (WBRT) or localized radiotherapy (LRT), including stereotactic radiosurgery and intraoperative radiotherapy, on the rate of recurrence both local and distal to the resection site in the treatment of brain metastases. METHODS We retrospectively identified patients who underwent surgery for brain metastasis at the Cleveland Clinic between 2004 and 2012. Institutional review board-approved chart review was conducted, and patients who had radiation before surgery, who had nonmetastatic lesions, or who lacked postadjuvant imaging were excluded. RESULTS The final analysis included 212 patients. One hundred fifty-six patients received WBRT, 37 received stereotactic radiosurgery only, and 19 received intraoperative radiotherapy. One hundred forty-six patients were deceased, of whom 60 (41%) died with no evidence of recurrence. Competing risks methodology was used to test the association between adjuvant modality and progression. Multivariable analysis revealed no significant difference in the rate of recurrence at the resection site (hazard ratio [HR] 1.46, P = .26) or of unresected, radiotherapy-treated lesions (HR 1.70, P = .41) for LRT vs WBRT. Patients treated with LRT had an increased hazard of the development of new lesions (HR 2.41, P < .001) and leptomeningeal disease (HR 2.45, P = .04). Median survival was 16.5 months and was not significantly different between groups. CONCLUSION LRT as adjuvant treatment to surgical resection of brain metastases is associated with an increased rate of development of new distant metastases and leptomeningeal disease compared with WBRT, but not with recurrence at the resection site or of unresected lesions treated with radiation.

Abstract
Breast cancer is the second most common cause of brain metastases and deserves particular attention in relation to current prolonged survival of patients with metastatic disease. Advances in both systemic therapies and brain local treatments (surgery and stereotactic radiosurgery) have led to a reappraisal of brain metastases management. With respect to this, the literature review presented here was conducted in an attempt to collect medical evidence-based data on the use of whole-brain radiotherapy for the treatment of brain metastases from breast cancer. In addition, this study discusses here the potential differences in outcomes between patients with brain metastases from breast cancer and those with brain metastases from other primary malignancies and the potential implications within a treatment strategy.

Abstract
BACKGROUND Optimal postoperative management paradigm for brain metastases remains controversial. OBJECTIVE To conduct a systematic review of the literature to understand the role of postoperative stereotactic radiosurgery after resection of brain metastases. METHODS We performed a MEDLINE search of the literature to identify series of patients with brain metastases treated with stereotactic radiosurgery after surgical resection. Outcomes including overall survival, local control, distant intracranial failure, and salvage therapy use were recorded. Patient, tumor, and treatment factors were correlated with outcomes through the use of the Pearson correlation and 2-way Student t test as appropriate. RESULTS Fourteen studies involving 629 patients were included. Median survival for all studies was 14 months. Local control was correlated with the median volume treated with radiosurgery (r = -0.766, P < .05) and with the rate of gross total resection (r = .728, P < .03). Mean crude local control was 83%; 1-year local control was 85%. Distant intracranial failure occurred in 49% of cases, and salvage whole-brain radiation therapy was required in 29% of cases. Use of a radiosurgical margin did not lead to increased local control or overall survival. CONCLUSION Our systematic review supports the use of radiosurgery as a safe and effective strategy for adjuvant treatment of brain metastases, particularly when gross total resection has been achieved. With all limitations of comparisons between studies, no increase in local recurrence or decrease in overall survival compared with rates with adjuvant whole-brain radiation therapy was found.

Abstract
BACKGROUND This guideline updates the second edition and addresses patients with particular forms of non-small cell lung cancer that require special considerations, including Pancoast tumors, T4 N0,1 M0 tumors, additional nodules in the same lobe (T3), ipsilateral different lobe (T4) or contralateral lung (M1a), synchronous and metachronous second primary lung cancers, solitary brain and adrenal metastases, and chest wall involvement. METHODS The nature of these special clinical cases is such that in most cases, meta-analyses or large prospective studies of patients are not available. To ensure that these guidelines were supported by the most current data available, publications appropriate to the topics covered in this article were obtained by performing a literature search of the MEDLINE computerized database. Where possible, we also reference other consensus opinion statements. Recommendations were developed by the writing committee, graded by a standardized method, and reviewed by all members of the Lung Cancer Guidelines panel prior to approval by the Thoracic Oncology NetWork, Guidelines Oversight Committee, and the Board of Regents of the American College of Chest Physicians. RESULTS In patients with a Pancoast tumor, a multimodality approach appears to be optimal, involving chemoradiotherapy and surgical resection, provided that appropriate staging has been carried out. Carefully selected patients with central T4 tumors that do not have mediastinal node involvement are uncommon, but surgical resection appears to be beneficial as part of their treatment rather than definitive chemoradiotherapy alone. Patients with lung cancer and an additional malignant nodule are difficult to categorize, and the current stage classification rules are ambiguous. Such patients should be evaluated by an experienced multidisciplinary team to determine whether the additional lesion represents a second primary lung cancer or an additional tumor nodule corresponding to the dominant cancer. Highly selected patients with a solitary focus of metastatic disease in the brain or adrenal gland appear to benefit from resection or stereotactic radiosurgery. This is particularly true in patients with a long disease-free interval. Finally, in patients with chest wall involvement, provided that the tumor can be completely resected and N2 nodal disease is absent, primary surgical resection should be considered. CONCLUSIONS Carefully selected patients with more uncommon presentations of lung cancer may benefit from an aggressive surgical approach.

Abstract
The development of brain metastases is common in patients with metastatic melanoma and heralds a particularly poor prognosis. The development of the immunological agent ipilimumab and targeted treatments such as the selective BRAF inhibitor vemurafenib have revolutionised the treatment of metastatic disease. Evidence from clinical trials suggest these drugs may be effective in the treatment of brain metastases from melanoma. However efficacy may be limited by a lack of penetration of the blood brain barrier (BBB) and by multi substrate efflux pumps expressed on the BBB. The role and sequencing of radiotherapy, both whole brain and stereotactic radiotherapy, is yet to be determined but combinations of radiotherapy and systemic therapies may further increase the effects of these drugs on brain metastases. Considering the impact of brain metastases on morbidity and mortality in metastatic melanoma, future research into systemic drug therapy for the treatment of brain metastases and improvements in BBB penetrance should be a priority.

Abstract
Brain metastases are the leading cause of intracranial malignancy and a major cause of mortality and morbidity. From 20 to 40% of cancer patients develop brain metastases. The irradiation of the whole brain remains the most commonly undertaken treatment, but should be discussed in relation to other therapeutic alternatives such as stereotactic radiotherapy or the use of new chemotherapy drugs. Its use according to pathology should be discussed. It can lead to a long-term neurocognitive toxicity that should be evaluated more precisely. This literature review aims to highlight the role of whole-brain radiotherapy used alone or in combination with other treatments.

Abstract
During the last decades, advances in diagnostic and therapeutic technologies have modified the management of brain metastases, which is currently tailored to the type of primary site and to prognostic factors isolated in multivariate analyses. The aim of this article is to take stock of the current state of knowledge regarding prognostic factors in the setting of brain metastases from breast cancer as well as prognostic classifications proposed in this context. An appropriate multidisciplinary treatment for each prognostic class will be then discussed in light of the results of major randomized controlled trials enrolling patients with brain metastases from breast cancer.

Abstract
The high rate of brain metastasis in patients with advanced melanoma has been a clinical challenge for oncologists. Despite considerable progress made in the management of advanced melanoma over the past two decades, improvement in overall survival has been elusive. This is due to the high incidence of CNS metastases, which progress relentlessly and which are only anecdotally responsive to systemic therapies. Surgery, stereotactic radiosurgery and whole-brain radiotherapy with or without cytotoxic chemotherapy remain the mainstay of treatment. However, new drugs have been developed based on our improved understanding of the molecular signaling mechanisms responsible for host immune tolerance and for melanoma growth. In 2011, the US FDA approved two agents, one antagonizing each of these processes, for the treatment of advanced melanoma. The first is ipilimumab, an anti-CTLA-4 monoclonal antibody that enhances cellular immunity and reduces tolerance to tumor-associated antigens. The second is vemurafenib, an inhibitor that blocks the abnormal signaling for melanoma cellular growth in tumors that carry the BRAF(V600E) mutation. Both drugs have anecdotal clinical activity for brain metastasis and are being evaluated in clinical trial settings. Additional clinical trials of newer agents involving these pathways are also showing promise. Therefore, targeted therapies must be incorporated into the multimodality management of melanoma brain metastasis.

Abstract
Background To evaluate the role of surgery and postoperative radiotherapy in the management of brain metastases (BM): a retrospective analysis for overall survival (OS), local and brain control (LC and BC) of a series of 329 patients with recursive partitioning analysis (RPA) I or II with 1 or 2 BM in a single institution. Methods Patients were treated either with combined surgical resection and whole brain radiation therapy (WBRT) in 104 cases (31.6%) or with WBRT alone in 225 cases (68.4%). Ninety-five patients (91.4%) who underwent surgery and WBRT and 147 (65.3%) who underwent WBRT alone benefited from a radiation boost to the metastatic site. Results The median OS was higher for patients RPA I compared to RPA II: 21.3 and 5.9 months (P < 0.0001), as well as for the surgical group compared to the radiation group: 20.2 vs 5.3 months (P < 0.0001), respectively. After the multivariate analysis, the improved OS was significantly associated with control of primary tumor (P = 0.0002) after surgical resection and with type of primary tumor (P = 0.002), absence of extracranial metastases (ECM) (P = 0.006), and high Karnofsky performance status (90 - 100 vs 70 - 80) (P = 0.003) after radiotherapy alone. The 12-, 24- and 36-months LC rates were 91.1%, 91.1% and 83.9%, respectively, after surgical resection and 81.2%, 63.1% and 57.3%, respectively, after radiotherapy alone (P = 0.005). In a univariate analysis, improved LC for the surgical group was also associated with the absence of ECM (P = 0.01) and for the radiation group, with a radiation boost (P = 0.01). The BC rates at 12, 24 and 36 months were 73.2%, 66.9% and 56%, respectively, in the surgical group and 75.7%, 49.6% and 42.4%, respectively, in the radiation group (P = 0.2). In our univariate analysis, improved BC after surgical resection was associated with control of primary tumor (P = 0.02). For patients in the radiation group, gender (P = 0.03) and a radiation boost (P = 0.0003) were significant prognostic factors in a univariate analysis. In our multivariate analysis, only the radiation boost was significant (P = 0.001). Conclusions Surgical resection followed by WBRT leads to a better outcome compared to WBRT alone for RPA I or II patients with 1 or 2 BM.

Abstract
BACKGROUND Colorectal cancer (CRC) rarely metastasizes to the brain, and the incidence rate has been reported to be 1-2%. Unfortunately, the median survival for patients with brain metastasis (BM) from CRC is short. In this study, we retrospectively investigated the BM from CRC and examined the prognostic factors. METHODS We retrospectively analyzed 29 CRC patients who developed BM; the lesions were diagnosed synchronously in 1 patient and metachronously in 28 patients. RESULTS After BM, the median survival time was 7.4 months. In the groups of patients who underwent surgical resection and radiation therapy, the median survival times were 8.3 and 7.4 months, respectively. The difference between the two groups was not statistically significant. The curability of the therapy for BM, number of BM, number of metastatic organs including the brain, and the CEA level at the time of treatment of the BM were significantly associated with the cancer-specific survival (P = 0.0044, 0.0229, 0.0019, and 0.0205, respectively). CONCLUSIONS The prognosis of patients with BM from CRC was associated with the curability of the therapy for BM, number of metastatic organs, and the serum CEA level. The modality of treatment had no significant impact on the outcome.

Abstract
BACKGROUND The optimal treatment for patients with a single brain metastasis is controversial. This study investigated the value of a radiation boost given in addition to neurosurgerical resection and whole-brain irradiation (WBI). PATIENTS AND METHODS In this retrospective study, outcome data of 105 patients with a single brain metastasis receiving metastatic surgery plus WBI (S + WBI) were compared to 90 patients receiving the same treatment plus a boost to the metastatic site (S + WBI + B). The outcomes that were compared included local control of the resected metastasis (LC) and overall survival (OS). In addition to the treatment regimen, eight potential prognostic factors were evaluated including age, gender, performance status, extent of metastatic resection, primary tumor type, extracerebral metastases, recursive partitioning analysis (RPA) class, and interval from first diagnosis of cancer to metastatic surgery. RESULTS The LC rates at 1 year, 2 years, and 3 years were 38%, 20%, and 9%, respectively, after S + WBI, and 67%, 51%, and 33%, respectively, after S + WBI + B (p = 0.002). The OS rates at 1 year, 2 years, and 3 years were 52%, 25%, and 19%, respectively, after S + WBI, and 60%, 40%, and 26%, respectively, after S + WBI + B (p = 0.11). On multivariate analyses, improved LC was significantly associated with OP + WBI + B (p = 0.006) and total resection of the metastasis (p = 0.014). Improved OS was significantly associated with age ≤ 60 years (p = 0.028), Karnofsky Performance Score > 70 (p = 0.015), breast cancer (p = 0.041), RPA class 1 (p = 0.012), and almost with the absence of extracerebral metastases (p = 0.05). CONCLUSION A boost in addition to WBI significantly improved LC but not OS following resection of a single brain metastasis.

Abstract
AIMS Treatment of brain metastases patients has included whole brain radiotherapy (WBRT) for over 50 years, and there is much data showing this to be associated with short-term gains. The integration of resection and radiosurgery to these patients allows some better prognostic groups to experience long-term local control and improvement in quality of life. The recursive partitioning analysis of the Radiation Therapy Oncology Group (RTOG) has been used as a predictive model for over a decade to identify three classes of patients. Number of lesions has been used to define treatment for a good prognostic subgroup that is eligible for surgery or radiosurgery, but there are few prospective studies of poorer prognosis brain metastases patients to evaluate the influence of number of lesions on the prediction of outcome. We examined patient, treatment and outcome parameters of all brain metastases patients in a 5-year period so that we could measure outcome and evaluate various factors on survival. METHODS AND RESULTS This was a population-based study of all brain metastases patients in Southern Alberta between 2000 and 2005. It used an Excel spreadsheet database and STATA 8 software to analyze outcomes. The study included 568 patients representing 4.4% of our radiotherapy population. Median age, performance status and distribution of primary disease sites were comparable with other large series. Overall survival for the whole group was 3.05 months. Independent factors predicting for improved overall survival included younger age, KPS <70, less than four lesions and the use of stereotactic radiosurgery. Presence of extracranial disease or persistence of primary disease did not adversely impact survival outcome. CONCLUSIONS This series shows that the number of lesions is a strong predictor of outcome. Integration of this factor into a decision-making model allows for identification of not only good prognosis patients who will benefit from aggressive treatment but it also facilitates decision making for poorer prognosis patients who are less likely to benefit from WBRT. Recursive partitioning RTOG class 2 and 3 patients with more than three lesions did particularly poor and had an overall survival of 3 months with WBRT. We question the value of WBRT in this subgroup and wonder if best supportive care would be more justifiable given the low survival figures achieved.

Abstract
PURPOSE This European Organisation for Research and Treatment of Cancer phase III trial assesses whether adjuvant whole-brain radiotherapy (WBRT) increases the duration of functional independence after surgery or radiosurgery of brain metastases. PATIENTS AND METHODS Patients with one to three brain metastases of solid tumors (small-cell lung cancer excluded) with stable systemic disease or asymptomatic primary tumors and WHO performance status (PS) of 0 to 2 were treated with complete surgery or radiosurgery and randomly assigned to adjuvant WBRT (30 Gy in 10 fractions) or observation (OBS). The primary end point was time to WHO PS deterioration to more than 2. RESULTS Of 359 patients, 199 underwent radiosurgery, and 160 underwent surgery. In the radiosurgery group, 100 patients were allocated to OBS, and 99 were allocated to WBRT. After surgery, 79 patients were allocated to OBS, and 81 were allocated to adjuvant WBRT. The median time to WHO PS more than 2 was 10.0 months (95% CI, 8.1 to 11.7 months) after OBS and 9.5 months (95% CI, 7.8 to 11.9 months) after WBRT (P = .71). Overall survival was similar in the WBRT and OBS arms (median, 10.9 v 10.7 months, respectively; P = .89). WBRT reduced the 2-year relapse rate both at initial sites (surgery: 59% to 27%, P < .001; radiosurgery: 31% to 19%, P = .040) and at new sites (surgery: 42% to 23%, P = .008; radiosurgery: 48% to 33%, P = .023). Salvage therapies were used more frequently after OBS than after WBRT. Intracranial progression caused death in 78 (44%) of 179 patients in the OBS arm and in 50 (28%) of 180 patients in the WBRT arm. CONCLUSION After radiosurgery or surgery of a limited number of brain metastases, adjuvant WBRT reduces intracranial relapses and neurologic deaths but fails to improve the duration of functional independence and overall survival.

Abstract
Adjuvant whole-brain radiation therapy (WBRT) after resection of single brain metastases remains controversial. Despite a phase III trial to the contrary, clinicians often withhold WBRT after resection of single brain metastases based on the argument that available evidence does not inform regarding treatment of all patients, such as those with radioresistant tumors. However, there is limited information about whether subpopulations benefit equally from WBRT after resection. Therefore, we undertook a retrospective study to determine the clinical, radiographic, and histologic features that influenced the effectiveness of adjuvant WBRT. We reviewed 358 patients with newly diagnosed, single brain metastases, who underwent resection, of which 142 (40%) received adjuvant WBRT and 216 (60%) did not. Median follow-up was 60.1 months. There were multiple tumor histologies, including 197 (55%) "radiosensitive" and 161 (45%) "radioresistant" tumors. Compared with observation, WBRT significantly reduced recurrence both locally (HR = 0.58; 95% CI 0.35-0.98, P = .04) and at distant brain sites (HR = 0.43, 95% CI 0.30-0.61, P < .001). Multivariate analyses demonstrated that withholding WBRT was an independent predictor of local and distant recurrence. For local recurrence, tumors with a maximum diameter of ≥3 cm that did not receive adjuvant WBRT had an increased risk of recurring locally (HR = 3.14, 95% CI 1.02-9.69, P = .05). For distant recurrence, patients whose primary disease was progressing and who did not receive WBRT had an increased risk of distant recurrence (HR = 2.16, 95% CI 1.01-4.66, P = .05). There was no effect of WBRT based on tumor type. Adjuvant WBRT significantly reduces local and distant recurrences in subsets of patients, particularly those with metastases >3 cm or with active systemic disease.

Abstract
Brain metastases are a frequent occurrence in cancer patients and result in significant morbidity and mortality. The three main treatments for brain metastases include surgery, radiation, and/or chemotherapy, alone or in combination. After resection alone, local recurrence rates are high. Whole brain radiation therapy can decrease the probability of recurrence; however, this has some disadvantages. Focal radiation therapy (FRT) may provide many of the same benefits without some of these disadvantages. In this study, we retrospectively analyzed patients with single brain metastases treated with FRT after surgery. Doses ranged from 14 Gy as single dose stereotactic radiosurgery (SRS) to 54 Gy in 27 2-Gy fractions as conformal fractionated radiotherapy. Four of the seven patients had a same-site recurrence, with an average time to recurrence of 115.5 d. Median dose in the patients that had same-site recurrence was 42 Gy. One of these patients is currently living. Two patients did not have recurrence, and one patient had a recurrence at a different site within the brain. The low rate of out-of-field recurrences during the patients life indicates focal radiation may be a reasonable therapeutic alternative. Given the number of patients with same-site recurrences, wide field margins around the tumor volume or higher radiation doses than those typically used in palliative regimens may be useful in post-excisional FRT. Additionally, we found that a longer delay in the initiation of FRT after initial diagnosis may result in a decreased time to same-site recurrence. However, further studies are warranted given the small number of patients in this study.

Abstract
The multimodality management of brain metastases has undergone significant refinement in the last decade. Although brain metastases remain a significant source of morbidity and mortality for many cancer patients, aggresive management has led to pronounced gains in neurological functioning, disease free survival and overall survival compared to standard treatment regimens consisting of only whole brain radiation therapy. Representative studies reviewing the role of aggressive management approaches including surgical resection with or without whole brain radiation therapy or non-surgical approaches employing stereotactic radiosurgery alone or in combination with whole brain radiation therapy are highlighted. Additionally, the emerging role of systemic agents showing distinct clinical activity in patients with brain metastases are also discussed. As we continue to gain advances in systemic therapies for metastatic disease, local control of brain metastases in these patients is likely to become more critical in improving survival and quality of life, thereby calling for a more aggressive multi-modal approach to this population of patients.

Abstract
OBJECT Treatment options for patients with brain metastasis include tumor resection, whole-brain radiation therapy, and radiosurgery. A single treatment is not useful in cases of multiple tumors, of which at least 1 is a cystic tumor. The purpose of this study was to assess the role of stereotactic drainage and Gamma Knife surgery (GKS) in the treatment of cystic brain metastasis. METHODS Between January 2001 and November 2005, 680 consecutive patients with brain metastases underwent GKS at our hospital, 30 of whom were included in this study (18 males and 12 females, mean age 60.6 +/- 11 years, range 38-75 years). Inclusion criteria were: 1) no prior whole-brain radiation therapy or resection procedure; 2) a maximum of 4 lesions on preoperative MR imaging; 3) at least 1 cystic lesion; 4) a Karnofsky Performance Scale score >or= 70; and 5) histological diagnosis of a malignant tumor. RESULTS Non-small cell lung carcinoma was the primary cancer in most patients (19 patients [63.3%]). A single metastasis was present in 13 patients (43.3%). There was a total of 81 tumors, 33 of which were cystic. Ten patients (33.3%) were in recursive partitioning analysis Class I, and 20 (66.6%) were in Class II. Before drainage the mean tumor volume was 21.8 ml (range 3.8-68 ml); before GKS the mean tumor volume was 10.1 ml (range 1.2-32 ml). The mean prescription dose to the tumor margin was 19.5 Gy (range 12-25 Gy). Overall median patient survival was 15 months. The 1- and 2-year survival rates were 54.7% (95% confidence interval 45.3-64.1%) and 34.2% (95% confidence interval 23.1-45.3%). Local tumor control was achieved in 91.3% of the patients. CONCLUSIONS The results of this study support the use of a multiple stereotactic approach in cases of multiple and cystic brain metastasis.

Abstract
BACKGROUND Patients with limited intracranial metastatic disease traditionally have been treated with surgery followed by WBRT. However, there is growing concern for the debilitating cognitive effects after WBRT in long-term survivors. We present a series of patients treated with surgery followed by SRS, while reserving WBRT as a salvage therapy for disease progression. METHODS Medical records from 15 patients with 1 to 2 cerebral metastases who underwent both resection and SRS were reviewed. Outcome measures included overall survival, survival by RPA class, EOR, local tumor control, progression of intracranial disease, need for WBRT salvage therapy, and COD. RESULTS Fifteen patients with cerebral metastases were treated with the combined surgery-SRS paradigm. Eight of the 15 patients (53.3%) were designated RPA class 1, with 6 of 15 (40.0%) in class 2 and 1 of 15 (6.7%) in class 3. Gross total resection was achieved in 12 cases (80.0%). Overall median survival was 20.0 months, with values of 22.0 and 13.0 months for RPA classes 1 and 2, respectively. Local recurrence occurred in 16.7% of those patients with GTR. Six patients (40.0%) went on to receive WBRT at a median of 8.0 months from initial presentation. Twelve patients (80.0%) had died at the completion of the study, and the COD was CNS progression in 33.3%. CONCLUSIONS Surgical resection combined with SRS is an effective treatment for selected patients with limited cerebral metastatic disease. Survival using this combined treatment was equivalent to or greater than that reported by other studies using surgery + WBRT or SRS + WBRT.

Abstract
BACKGROUND The current study was conducted to compare 2 treatment regimens including surgical resection and whole-brain radiotherapy (WBRT) for patients with 1 to 2 brain metastases. METHODS A total of 201 patients with recursive partitioning analysis (RPA) class 1 to 2 disease with 1 to 2 resectable brain metastases were analyzed retrospectively. Patients underwent either resection of the metastases plus WBRT with 10 fractions of 3 grays (Gy) each or 20 fractions of 2 Gy each (99 patients; Group A) or the same treatment plus a WBRT boost to the metastatic site (10 fractions of 3 Gy each plus 5 fractions of 3 Gy each or 20 fractions of 2 Gy each plus 5 fractions of 2 Gy each) (102 patients; Group B). Eight other potential prognostic factors were evaluated with regard to overall survival (OS), brain control (BC), and local control of resected metastases (LC): age, gender, Karnofsky performance status, extent of surgical resection, tumor type, extracranial metastases, RPA class, and interval from tumor diagnosis to WBRT. RESULTS Group B patients had better 1-year OS (66% vs 41%; P < .001). On multivariate analysis of OS, treatment regimen (relative risk [RR] of 1.94; P < .001), extent of surgical resection (RR of 1.80; P = .001), and interval from tumor diagnosis to WBRT (RR of 1.62; P = .010) were found to be statistically significant. On multivariate analysis of BC, treatment regimen (RR of 2.15; P = .002), extent of surgical resection (RR of 2.78; P < .001), and interval from tumor diagnosis to WBRT (RR of 1.52; P = .034) were found to be statistically significant. On multivariate analysis of LC, treatment regimen (RR of 2.31; P = .002) and extent of surgical resection (RR of 3.79; P < .001) were found to be statistically significant. On RPA class subgroup analyses, outcome was found to be significantly better with a WBRT boost in both RPA class 1 and class 2 patients. A WBRT boost resulted in better outcome after both complete and incomplete surgical resection. However, the results concerning BC and LC were not found to be statistically significant if surgical resection was incomplete. CONCLUSIONS After surgical resection of 1 to 2 brain metastases, a boost of 10 to 15 Gy in addition to WBRT was found to improve outcome. After incomplete surgical resection, further dose escalation to the metastatic site may be considered.

Abstract
BACKGROUND The objective of this study was to compare stereotactic radiosurgery (SRS) alone with resection plus whole-brain radiotherapy (WBRT) for the treatment of patients in recursive partitioning analysis (RPA) class 1 and 2 who had 1 or 2 brain metastases. METHODS Two hundred six patients in RPA class 1 and 2 who had 1 or 2 brain metastases were analyzed retrospectively. Patients in Group A (n = 94) received from 18 grays (Gy) to 25 Gy SRS, and patients in Group B (n = 112) underwent resection of their metastases and received 10 x 3 Gy/20 x 2 Gy WBRT. Eight other potential prognostic factors were evaluated regarding overall survival (OS), brain control (BC), and local control (LC) of treated metastases: age, sex, performance status, tumor type, number of brain metastases, extracranial metastases, RPA class, and interval from tumor diagnosis to treatment of brain metastases. RESULTS A comparison of the 2 treatment groups did not reveal significantly different OS (P = .19), BC (P = .52), or LC (P = .25). In RPA subgroup analyses, outcome also did not differ significantly for either RPA class of patients (P values from .21 to .83). On multivariate analysis, improved OS was associated with age < or =60 years (relative risk [RR], 1.75; P = .002), better performance status (RR, 1.67; P = .015), no extracranial metastases (RR, 2.84; P < .001), interval from tumor diagnosis to treatment >12 months (RR, 1.70; P = .003), and RPA class 1 (RR, 1.51; P = .016). Improved BC was associated with a single metastasis (RR, 1.54; P = .034) and an interval from tumor diagnosis to treatment >12 months (RR, 1.58; P = .019), and improved LC was associated with an interval from tumor diagnosis to treatment >12 months (RR, 1.59; P = .047). CONCLUSIONS SRS alone appeared to be as effective as resection plus WBRT in the treatment of 1 or 2 brain metastases for patients in RPA class 1 and 2. Patient outcomes were associated with age, Karnofsky performance status, number of brain metastases, extracranial metastases, RPA class, and interval from tumor diagnosis to treatment.

Abstract
OBJECT The aim of this study was to test the validity of the hypothesis that patients in whom brain metastasis is the first indication of an undiagnosed primary tumor have a better chance of survival than similar patients with a known primary lesion. METHODS Between January 1983 and December 1998, 342 patients with computed tomography-diagnosed brain metastases were treated at a single institution. Information on potential prognostic factors, including primary diagnosis status, was collected retrospectively. Univariate and multivariate analyses were performed to identify prognostic factors related to survival. Survival was not statistically different between patients with an undiagnosed primary (UDP) lesion and those with a diagnosed primary (DP) tumor (6 and 4.5 months, respectively; p = 0.097). In the UDP group (122 patients [36%]), survival was not affected by the eventual identification of the primary disease (p = 0.905). The median survival for the entire population was 5.2 months, with 1-, 2-, and 3-year survival rates of 25, 11, and 4%, respectively. Prognostic factors for the overall population included treatment (p < 0.0001), an age less than 65 years (p = 0.004), discharge status (p < 0.001), absence of systemic metastasis (p = 0.036), and asymptomatic cerebral metastasis (p = 0.05). CONCLUSIONS Treatment modality was the most significant independent variable affecting survival in patients with brain metastases. Eventual identification of a primary tumor does not affect overall survival; therefore, delaying therapeutic intervention in pursuit of a primary diagnosis may not be appropriate. Data in this study failed to demonstrate a statistically significant difference in survival between patients with UDP and those with DP lesions, on first presenting with brain metastases.

Abstract
Brain metastases are an important cause of mortality and morbidity. The prognosis is poor with a median survival of less than one year in the majority of cases. From this review, whole-brain irradiation clearly appears as the standard treatment. However, its role could be discussed according to newer treatment modalities, radiosurgery or new chemotherapies. Post irradiation neurocognitive status remains insufficiently known.

Abstract
PURPOSE To report on 32 patients who survived > or = 5 years from brain metastases treated at a single institution. METHODS AND MATERIALS The records of 1288 patients diagnosed with brain metastases between 1973 and 1999 were reviewed. Patients were treated with whole-brain radiation therapy (WBRT), surgery, and/or stereotactic radiosurgery (SRS). Thirty-two (2.5%) > or = 5-year survivors were identified. Factors contributing to long-term survival were identified. RESULTS Median survival was 9.3 years for > or = 5-year survivors. Seven of these patients lived > or = 10 years. Female gender was the only patient characteristic that correlated with better survival (p = 0.0369). When these patients were compared with < 5-year survivors, age < 65 years (p = 0.0044), control of the primary at diagnosis (p = 0.0052), no systemic disease (p = 0.0012), recursive partitioning analysis (RPA) Class 1 (p = 0.0002 with Class 2; p = 0.0022 with Class 3), and single brain metastasis (p = 0.0018) were associated with long-term survival in the univariate logistic regression model. In the multivariate model, RPA Class 1 compared with Class 2 (OR = 0.39, p = 0.0196), surgery (OR = 0.16, p < 0.0001), and SRS (OR = 0.41, p = 0.0188) were associated with long-term survival. CONCLUSIONS For patients with good prognostic factors such as young age, good RPA characteristics and single metastasis, treatment with surgery or SRS offers the best chance for long-term survival.
