Abstract
BACKGROUND We conducted a randomized trial of prophylactic cranial irradiation in patients with extensive small-cell lung cancer who had had a response to chemotherapy. METHODS Patients between the ages of 18 and 75 years with extensive small-cell lung cancer were randomly assigned to undergo prophylactic cranial irradiation (irradiation group) or receive no further therapy (control group). The primary end point was the time to symptomatic brain metastases. Computed tomography or magnetic resonance imaging of the brain was performed when any predefined key symptom suggestive of brain metastases was present. RESULTS The two groups (each with 143 patients) were well balanced regarding baseline characteristics. Patients in the irradiation group had a lower risk of symptomatic brain metastases (hazard ratio, 0.27; 95% confidence interval [CI], 0.16 to 0.44; P<0.001). The cumulative risk of brain metastases within 1 year was 14.6% in the irradiation group (95% CI, 8.3 to 20.9) and 40.4% in the control group (95% CI, 32.1 to 48.6). Irradiation was associated with an increase in median disease-free survival from 12.0 weeks to 14.7 weeks and in median overall survival from 5.4 months to 6.7 months after randomization. The 1-year survival rate was 27.1% (95% CI, 19.4 to 35.5) in the irradiation group and 13.3% (95% CI, 8.1 to 19.9) in the control group. Irradiation had side effects but did not have a clinically significant effect on global health status. CONCLUSIONS Prophylactic cranial irradiation reduces the incidence of symptomatic brain metastases and prolongs disease-free and overall survival.

Abstract
As therapy for systemic cancers improves, an increasing number of patients are developing brain metastases. Although conventional therapy with surgery, radiation therapy and radiosurgery has improved the outcome of a significant number of patients, many develop multiple lesions that are not amenable to standard treatments. In this review, the current role of chemotherapy and targeted molecular agents for brain metastases is summarized and future directions are discussed.

Abstract
Solid tumour brain metastases are a frequent clinical dilemma for oncologists and general physicians. The sound management of brain metastases requires a multidisciplinary approach. In this review we discuss the diagnosis and management of brain metastases including the role of surgery, radiotherapy, and chemotherapy. The standard approaches of surgical excision and primary radiotherapy have evolved from randomised studies. However, controversies remain regarding post-surgery irradiation in the setting of a solitary metastasis and the role of palliative chemotherapy.

Abstract
The use of chemotherapy for the treatment of brain metastases arising from lung cancer has been limited by poor efficacy and high toxicity. Temozolomide, an orally bioavailable alkylating agent that crosses the blood-brain barrier, has activity against brain metastases from both small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) when used as a single agent, but response rates are low. Preclinical experiments and early clinical studies in other malignancies indicate that temozolomide may have additive or synergistic effects when used with other chemotherapeutic agents. We report a case of a patient with SCLC with recurrent brain metastases after treatment with multiple chemotherapeutic regimens and whole-brain radiation therapy (WBRT) who was treated with temozolomide (150 mg/m(2) for 5 days in a 28-day cycle) and oral etoposide (50 mg/m(2) for 10 days in a 28-day cycle). A second patient with NSCLC and brain metastases who progressed after treatment with chemotherapy and WBRT was treated with temozolomide (150 mg/m(2) for 5 days in a 28-day cycle) and gemcitabine (1,000 mg/m(2) weekly for 2 weeks in a 3- week cycle). In both patients, the temozolomide regimens were extremely well tolerated and resulted in dramatic and durable responses. The combination of temozolomide with other chemotherapeutic agents represents a promising strategy for treating patients with lung cancer and recurrent brain metastases and merits further study.

Abstract
The purpose of this multicentre phase II study was to evaluate the efficacy and toxicity of topotecan in pretreated patients with small-cell lung cancer (SCLC) who relapsed with symptomatic brain metastases. 30 patients with a median age of 62 years were entered into the study. 22 patients received the initially planned dose of 1.5 mg/m(2) topotecan as a 30-min intravenous (i.v.) infusion for 5 consecutive days every 3 weeks. Due to the observed thrombocytopenia, the dose was reduced to 1.25 mg/m(2) in the last 8 patients. All 30 patients were pretreated with chemotherapy: 14 with one and 16 with at least two protocols. 8 patients had prior whole-brain iradiation (WBI): 7 in the prophylactic and 1 in the palliative setting. Concomitant systemic metastases were recorded in 24 patients at the time of brain relapse. Cerebral metastases responded in 33% of patients (10/30; three complete responses (CR) and seven partial responses (PR)). Noteworthy is the fact that response was achieved in 4 of 8 patients pretreated by WBI (3 in prophylactic and 1 in palliative setting). The systemic response rate was 29% (7/24). Median time to progression was 3.1 months (range 0.25-14.2+ months), median survival from the beginning of this study was 3.6 months (range 0.25-14.2+ months). Therapy was generally well tolerated, with myelotoxicity being the most common adverse event. Grade 3 leucocytopenia according to the Common Toxicity Criteria (CTC) occurred in 28% (23/83) of the courses and grade 4 in 22% (18/83). Grade 3 thrombocytopenia was observed in 17% of the courses (14/83) and grade 4 in 11% (9/83). 17% of patients (5/30) had a documented grade 3 infection. These results using topotecan are promising in heavily pretreated patients with SCLC brain metastases and merit further evaluation.

Abstract
The EORTC Lung Cancer Group (LCG) is a multidisciplinary international group of experts performing clinical research in lung cancer since 1962. Originally, the group consisted mainly out of French and Belgian investigators and expanded gradually into a wide range of investigators from all European Union countries, as well as some investigators from Switzerland, Poland, Czech Republic, Egypt, Slovenia, South Africa, Peru, Brazil and Cyprus. Despite the wide collaboration, it remains a difficult task to perform high quality large clinical research trials to answer important scientific questions in the treatment of lung cancer. For this reason, the EORTC Lung Cancer Group has invested a lot of efforts in promoting worldwide, randomised phase III studies in collaboration with other Groups. Furthermore, the LCG promotes small phase II trials of new drugs or treatments for lung cancer and stimulates the investigation of new strategies and treatments for rare intrathoracic malignancies.

Abstract
Chemotherapy is the treatment of choice in metastatic stage of small-cell lung cancer (SCLC). Radiation therapy, surgery and other forms of therapy are only included in special treatment situations, particularly for different local problems. A wide range of chemotherapeutic agents have proven to be effective in SCLC, including carboplatin, cisplatin, cyclophosphamide, doxorubicin, epirubicin, etoposide, ifosfamide, teniposide and vincristine. However, treatment results could not be improved over the last 10 years and the median survival of patients with metastatic disease is limited to 7-10 months. New agents like docetaxel, gemcitabine, irinotecan, paclitaxel, topotecan and vinorelbine have shown promising results in phase-II investigations. Yet, no evidence is provided from randomized trials to employ these drugs in first line treatment. Clearly, polychemotherapy is superior to single agent treatment. Compared to the combination of cisplatin and etoposide, no other combination has clearly shown improved results in large phase-III randomised trials, yet. The combination of cisplatin and irinotecan has also shown promising results in a single randomised trial with the need to be confirmed in larger settings. Neither extending the initial treatment beyond the median number of six cycles, nor maintenance treatment have-so far-resulted in any increase in survival results for patients with metastasised SCLC. Nor has dose-intensification, which causes significantly higher toxicities in patients, shown a clear impact on the overall survival of these patients. Brain metastases represent a high frequent complication associated with SCLC. In these cases, the combination of chemotherapy and whole brain radiation therapy is advocated. Second-line treatment should always be considered in patients with relapse or failure to first-line therapy. In addition to a rechallenging with the prior drug combination or selecting a different potentially non-cross resistant one, monotherapy with topotecan proved to be effective as well. In summary, up to now, no standard chemotherapy combination exists for metastatic SCLC. The individual therapy strategy can only be selected by considering the clinically relevant conditions of the patient.

Abstract
Brain is the most common site of metastatic spread in small-cell lung cancer (SCLC). Approximately 10% of SCLC patients have brain metastases (BM) already at diagnosis and an additional 40% will develop central nervous system (CNS) involvement during their disease course. Although whole brain radiotherapy and corticosteroids is considered the treatment of choice, accumulating evidence suggests that systemic chemotherapy may also play an important role. The concept of the brain as a pharmacologic sanctuary site for established metastases is in contrast with recent clinical observations of frequent BM responses with systemic chemotherapy. During the last decade, several reports about the effect of systemic chemotherapy on BM from SCLC have been published. Pooled data from five studies report 66% response rate (RR) in 64 patients with initial BM. In addition, an average RR of 36% is derived from five studies including 135 patients with delayed BM treated with systemic single agent chemotherapy. Among new drugs with activity in patients with SCLC brain metastases, camptothecin analog topotecan is one of the most promising with a 52% RR. Although whole brain radiation remains the standard treatment of established BM in SCLC there is an emerging role for systemic chemotherapy, particularly with the use of new active drugs as part of combined modality treatments.

Abstract
PURPOSE Approximately 60% of patients with small-cell lung cancer (SCLC) develop brain metastases. Whole-brain radiotherapy (WBRT) gives symptomatic improvement in more than 50% of these patients. Because brain metastases are a sign of systemic progression, and chemotherapy was found to be effective as well, it becomes questionable whether WBRT is the only appropriate therapy in this situation. PATIENTS AND METHODS In a phase III study, SCLC patients with brain metastases were randomized to receive teniposide with or without WBRT. Teniposide 120 mg/m(2) was given intravenously three times a week, every 3 weeks. WBRT (10 fractions of 3 Gy) had to start within 3 weeks from the start of chemotherapy. Response was measured clinically and by computed tomography of the brain. RESULTS One hundred twenty eligible patients were randomized. A 57% response rate was seen in the combined-modality arm (95% confidence interval [CI], 43% to 69%), and a 22% response rate was seen in the teniposide-alone arm (95% CI, 12% to 34%) (P<.001). Time to progression in the brain was longer in the combined-modality group (P=.005). Clinical response and response outside the brain were not different. The median survival time was 3.5 months in the combined-modality arm and 3.2 months in the teniposide-alone arm. Overall survival in both groups was not different (P=.087). CONCLUSION Adding WBRT to teniposide results in a much higher response rate of brain metastases and in a longer time to progression of brain metastases than teniposide alone. Survival was poor in both groups and not significantly different.

Abstract
Brain metastases are common in patients with small-cell lung cancer (SCLC) and are usually fatal. About half of all patients who develop brain metastases will remain symptomatic at their time of death, even if the immediate cause of death is not neurologic. While it has been argued that the obtundation that sometimes comes with brain metastases may be a relatively easy way to die, studies which have examined the quality of life of individuals developing brain metastases dispute this. For most patients and their families, the impairment of physical, cognitive, and affective function which accompanies most brain metastases is highly distressing and can be seen as a "loss" of the patient even before his/her death. Thus, improved treatment of overt brain metastases will be of palliative value, and eradication of microscopic disease in the brain may cure patients whose disease in other sites has been eradicated. Prophylactic cranial irradiation (PCI) for patients who have achieved a complete response to induction therapy markedly reduces the risk of central nervous system relapse and modestly but significantly improves survival. Despite the use of PCI, many patients with SCLC will develop brain metastases, and there is increasing interest in surgical treatment of patients with solitary lesions and the use of systemic chemotherapy in treating patients, with both SCLC and non small-cell lung cancer, who have multifocal brain metastases which are minimally symptomatic, particularly when these patients also have extracranial metastatic disease.

Abstract
In lung cancer patients brain metastases develop with a high frequency. For years radiotherapy has been the standard treatment for these patients. Here we review the experience with chemotherapy for brain metastases in lung cancer patients. The concept of the brain as pharmacological sanctuary site when brain metastases are present is challenged and it is argued that chemotherapy does play a role in this situation. Recent clinical trials indicate that the combination of chemotherapy and radiotherapy may become the standard treatment for lung cancer patients with brain metastases. It is unclear whether for micrometastatic disease to the brain, blood brain barrier function is of importance for the outcome of chemotherapy in lung cancer patients with respect to the development of overt brain metastases. Areas of improvement of delivery of cytotoxic agents to the brain when brain metastases have not yet developed are discussed.

Abstract
Extrapulmonary small cell carcinoma (EPSCC) is a distinct clinical and pathological entity other than small cell carcinoma of the lung. We present a case with EPSCC, with neurologic impairment due to brain metastases at initial diagnosis, which showed a complete response to combination chemotherapy. A 55-year-old male patient was first admitted with a mass of 6 x 6 cm in diameter in the right cervical region. The diagnosis of small cell carcinoma was entertained with immunohistopathologic and light microscopic findings. During the period of investigation the tumor showed rapid progression and the patient had neurologic dysfunction with right hemiparesia, and papilla oedema in fundoscopy. Cranial CT showed supratentorial multiple cranial metastases and peritumoral oedema. Since the patient refused radiotherapy, combination chemotherapy was started (Etoposide 100 mg/sq m i.v., days 1,3,5 and cisplatin 80 mg/sq m i.v., day 1). A fast response to the chemotherapy was observed with rapid disappearance of the cervical mass. Following six cycles of the chemotherapy the patient recovered fully and all the lesions disappeared with CT.

Abstract
Fourteen patients with brain metastases (BM) of solid tumors received intravenous cisplatinum, 40 mg/m2/day and etoposide, 150 mg/m2/day, for 3 days every 3 weeks. Primary tumors were lung (8 patients), breast (4), colon (1), and stomach (1). Two patients responded (1 complete response in a poorly differentiated lung cancer patient and 1 partial response in a breast cancer patient). The overall response rate was 14%, with a median survival of 6 months. Main toxicity was grade 3-4 neutropenia that occurred in 36% of patients. There were no toxic-related deaths. Chemotherapy as a single therapeutic regimen seems not to be an effective treatment for BM from relatively resistant solid tumors. Moreover, it produces rather high, although not life-threatening, hematologic toxicity.

Abstract
From September 1986 until December 1991, 139 patients with histologically-proven small cell lung cancer, age < 75 years, performance status > 40, absence of brain metastases and no previous treatment, were randomised to receive either CEV cyclophosphamide 1000 mg/m2 intravenous (i.v.), epirubicin 70 mg/m2 i.v., vincristine 1.2 mg/m2 i.v., every 3 weeks or PE (cisplatin 20 mg/m2 i.v. and etoposide 75 mg/m2 i.v. for 5 consecutive days, every 3 weeks) for six cycles. After three cycles, responding patients received radiotherapy to the chest (45 Gy/15 sessions) and to the brain (30 Gy/10 sessions--only in patients with limited disease achieving complete remission). 3 patients were ineligible. Patient characteristics included (CEV/PE) total number 66/70, median age 60/61 years, median performance status 80/80, extended disease 33/48 cases (P = 0.04). In evaluable patients, 42/62 (67.7%) responded to CEV while 42/58 (72.4%) responded to PE (P = non-significant); respective complete response rates were 16.1 and 29.3% (P = non-significant) and respective complete response rates in patients with extended disease were 9.4 and 28.9% (P = 0.03). Median survival was 10.5 months, without significant differences in the two treatment arms, even after adjustment for stage. PE was less well tolerated than CEV. Although PE is more active than CEV in certain subsets of patients, its apparent inability to improve survival in this and in other studies questions its routine use in small cell lung cancer.

Abstract
Patients with brain metastases from small cell lung cancer (SCLC) have a poor prognosis. Although most patients die from metastatic disease outside the central nervous system, this disabling metastatic site often needs treatment to mitigate the signs and symptoms of intracranial disease. The effect of carboplatin (400 mg/m2 every 4 weeks) as second line treatment for recurrent or progressive brain metastases was studied in 20 SCLC patients. 19 patients could be evaluated: 16 by contrast enhanced brain computer tomography (CT) scan (2 patients had complete response, 6 partial response, 4 stable disease and 4 progressive disease) and 3 patients clinically, who had progressive disease. The objective response rate in the brain was 40% (95% CI:22-61%). The median response duration was 8 weeks (range 2-29). The median survival was 15 weeks (range 1-44). Previous cranial irradiation appeared to be beneficial for survival. There was only mild haematological and gastrointestinal toxicity. Carboplatin has activity against brain metastases and gives palliation in responding patients.

Abstract
Penetration of etoposide into the cerebrospinal fluid, brain tumor, and brain tissue after intravenous administration was investigated in patients presenting with malignant brain tumors. A relatively low dose (55-65 mg/m2) was used to compare intravenous with oral administration. High-performance liquid chromatography with fluorescence detection was used to evaluate drug levels. Plasma and cerebrospinal fluid levels of etoposide after oral administration (50-150 mg/day) were also studied so as to determine the adequate oral dose for the treatment of malignant brain tumors. The peak plasma concentration after intravenous administration ranged from 7.01 to 10.47 micrograms/ml, varying in proportion to the injected dose, whereas that after oral administration was lower, namely, 1.44-4.99 micrograms/ml, and was unstable when the oral dose was 150 mg daily. The peak cerebrospinal fluid level following either intravenous or oral administration was much lower than the plasma concentration and was influenced by the peak plasma level and the sampling site. The etoposide concentration in cerebrospinal fluid taken from the subarachnoid space and ventricle of patients displaying no tumor invasion and of those presenting with meningeal carcinomatosis and in cerebrospinal fluid taken from the dead space after tumor resection was 0.7% +/- 0.5%, 3.4% +/- 1.0%, and 7.2% +/- 8.5%, respectively, of the plasma concentration. Serial oral administration did not result in the accumulation of etoposide in cerebrospinal fluid. The tumor concentration (1.04-4.80 micrograms/g) was 14.0% +/- 2.9% of the plasma level after intravenous administration, was related to the injected dose, and was approximately twice the concentration detected in the brain tissue. Therefore, a relatively low dose of etoposide injected intravenously penetrates the brain tumor at an efficacious concentration. Our results indicate than an oral dose of 100 mg etoposide be given for malignant brain tumors, as limited penetration of the drug into the intracranial region was observed.

Abstract
Chemotherapy for brain metastases has been considered ineffective because the drugs do not penetrate the intact blood brain barrier. Alternate explanations for past failures of chemotherapy include observations that 1) many solid tumors which metastasize to brain are drug-resistant regardless of location, 2) brain metastases often occur following failure of primary chemotherapeutic regimens to control systemic metastases, and 3) previous trials of chemotherapy employed agents other than those known to be most effective against the primary malignancy. Furthermore, laboratory studies have demonstrated that cytotoxic levels of many drugs can be measured in tumor tissue from primary and metastatic brain tumors. These clinical and pharmacologic observations suggest that chemotherapy would be expected to have limited value unless known effective combination regimens are employed as first-line therapy in chemosensitive malignancies. Recent reports of chemotherapy for patients with brain metastases from small cell lung carcinoma, gestational choriocarcinoma, germ cell malignancies, and breast carcinoma do describe response rates in the brain similar to those in other organ sites. In conclusion, chemotherapy for cerebral metastases can be expected to be effective only when effective drugs for systemic metastases are available. While the blood-brain barrier may be an additional detriment to successful treatment, other factors may be more important.

Abstract
Brain metastases are a well recognized problem in patients with small cell lung cancer (SCLC). Most patients are treated with whole brain cranial irradiation therapy which frequently improves symptoms. In this report we present data on two patients who achieved radiologically confirmed complete resolution of brain metastases treated with standard dose chemotherapy for SCLC.
