Purpose A retrospective review of the Southwest Oncology Group (SWOG) database was undertaken to review the incidence and timing of diagnosis of brain metastases in patients undergoing combined-modality therapy for stage III non–small-cell lung cancer (NSCLC). Patients and Methods Four hundred twenty-two eligible, assessable patients with stage IIIA/B NSCLC were treated on four SWOG protocols. Treatment varied with protocol but consisted of concurrent cisplatin-etoposide and radiation in all patients, with a surgery arm in two of the four protocols. Results Of the 422 total patients, 268 (64%) have experienced disease progression; 54 relapses (20%) were in brain only, 17 (6.5%) were in brain and other sites simultaneously, and 197 (63.5%) were in sites other than brain. Of the 268 patients with disease progression, progression in the brain only, in the brain and other sites, and not in the brain occurred in 20%, 6%, and 74% of patients, respectively. Time from treatment to diagnosis of disease progression in the brain in 71 patients was as follows: during treatment, 16 relapses (22.5%); 0 to 16 weeks after treatment, 17 relapses (24%); 16 weeks to 6 months after treatment, 10 relapses (14%); 6 to 12 months after treatment, 16 relapses (22.5%); and more than 12 months after treatment, 12 relapses (17%). Nonsquamous histology and young patient age were the only significant predictors for increased risk of early relapse with brain metastases. Conclusion Brain metastases often develop early in the course of treatment for stage IIIA/B NSCLC. The statistical designs of ongoing trials of prophylactic cranial irradiation in stage III NSCLC have taken this into account.

PURPOSE To assess the feasibility of concurrent chemotherapy and irradiation (chemoRT) followed by surgery in locally advanced non-small-cell lung cancer (NSCLC) in a cooperative group setting, and to estimate response, resection rates, relapse patterns, and survival for stage subsets IIIA(N2) versus IIIB. PATIENTS AND METHODS Biopsy proof of either positive N2 nodes (IIIAN2) or of N3 nodes or T4 primary lesions (IIIB) was required. Induction was two cycles of cisplatin and etoposide plus concurrent chest RT to 45 Gy. Resection was attempted if response or stable disease occurred. A chemoRT boost was given if either unresectable disease or positive margins or nodes was found. RESULTS The median follow-up time for 126 eligible patients [75 stage IIIA(N2) and 51 IIIB] was 2.4 years. The objective response rate to induction was 59%, and 29% were stable. Resectability was 85% for the IIIA(N2) group eligible for surgery and 80% for the IIIB group. Reversible grade 4 toxicity occurred in 13% of patients. There were 13 treatment-related deaths (10%) and 19 others (15%) died of causes not related to toxicity or tumor. Of 65 relapses, 11% were only locoregional and 61% were only distant. There were 26 brain relapses, of which 19 were the sole site or cause of death. There was no survival difference (P = .81) between stage IIIA(N2) versus stage IIIB (median survivals, 13 and 17 months; 2-year survival rates, 37% and 39%; 3-year survival rates, 27% and 24%). The strongest predictor of long-term survival after thoracotomy was absence of tumor in the mediastinal nodes at surgery (median survivals, 30 v 10 months; 3-year survival rates, 44% v 18%; P = .0005). CONCLUSION This trimodality approach was feasible in this Southwest Oncology Group (SWOG) study, with an encouraging 26% 3-year survival rate. An Intergroup study is currently being conducted to determine whether surgery adds more to the risk or to the benefit of chemoRT.

PurposeConcurrent chemoradiotherapy is standard treatment for patients with inoperable stage III non–small-cell lung cancer (NSCLC). A phase II study by the Southwest Oncology Group using consolidation docetaxel after cisplatin (P), etoposide (E), and radiation (XRT) resulted in a median survival time (MST) of 26 months. This randomized phase III trial evaluated whether consolidation docetaxel was responsible for this improved survival.Patients and MethodsEligible patients had stage IIIA or IIIB NSCLC, baseline performance status of 0 to 1, forced expiratory volume in 1 second ≥ 1 L, and less than 5% weight loss. Patients received P 50 mg/m2intravenously (IV) on days 1, 8, 29, and 36 and E 50 mg/m2IV on days 1-5 and 29-33 concurrently with chest XRT to 59.40 Gy. Patients who did not experience progression were randomly assigned to docetaxel 75 mg/m2IV every 21 days for three cycles versus observation. The primary end point was to compare overall survival (Kaplan-Meier analysis).ResultsOn the basis of evidence of futility, a data and safety monitoring board recommended early termination after an analysis of the initial 203 patients. Patient characteristics (n = 203) were as follows: 34% female; median age, 63 years; 39.4% stage IIIA; and 60.6% stage IIIB. One hundred forty-seven (72.4%) of 203 patients were randomly assigned to docetaxel (n = 73) or observation (n = 74). Grade 3 to 5 toxicities during docetaxel included febrile neutropenia (10.9%) and pneumonitis (9.6%); 28.8% of patients were hospitalized during docetaxel (v 8.1% in observation arm), and 5.5% died as a result of docetaxel. The MST for all patients (n = 203) was 21.7 months; MST was 21.2 months for docetaxel arm compared with 23.2 months for observation arm (P = .883).ConclusionConsolidation docetaxel after PE/XRT results in increased toxicities but does not further improve survival compared with PE/XRT alone in patients with stage III inoperable NSCLC.

PURPOSE A phase II study was conducted by the Southwest Oncology Group (SWOG) to assess the efficacy and toxicity of concurrent carboplatin, etoposide, and thoracic radiation (XRT) in a defined population of poor-risk patients with stage III non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Patients with stage III NSCLC were eligible if they were excluded from cisplatin-based protocols because of poor pulmonary or renal function, history of congestive heart failure, hearing loss, peripheral neuropathy, or weight loss. Carboplatin 200 mg/m2 daily intravenously days 1, 3, 29, and 31 and etoposide 50 mg/m2 daily intravenously days 1 through 4 and 29 through 32 were administered. Beginning day 1, XRT was delivered at 1.8 to 2.0 Gy daily to a total dose of 61 Gy. RESULTS Within a period of 1 year, 63 patients were registered and 60 were eligible. Patient characteristics were age 47 to 79 years, performance status 0 to 1 (82%) and 2 (18%), and stages IIIA (60%) and IIIB (40%) NSCLC. The most common grades 3 and 4 toxicities included leukopenia (50%), thrombocytopenia (23%), and esophagitis (15%). There were no treatment-related deaths. The overall confirmed response rate was 29%, and median overall survival was 13 months (95% confidence interval, 11 to 14 months). The 2-year survival rate was 21%. CONCLUSION This chemoradiotherapy regimen is well tolerated in poor-risk patients and yields a median survival similar to that of good-risk patients who received cisplatin-based chemoradiotherapy. This chemoradiotherapy regimen will be compared with XRT alone in poor-risk patients with stage III NSCLC in a randomized phase III trial.

Purpose Lung cancer is the leading cause of cancer mortality in the United States. We sought to review our experience with surgically staged IIIA (N2) non–small-cell lung cancer (NSCLC), focusing on the patterns of failure in consecutively treated patients from 1988 to 2000. Patients and Methods The records of 177 patients were reviewed. Collected data included stage, histology, use of chemotherapy and radiation, initial and subsequent sites of failure, and survival. One hundred twenty-four patients have died; follow-up time is 35 months among the remaining patients. Results The median survival from the time of surgery was 21.0 months, with a 3-year overall survival (OS) of 34%. Nodal downstaging to N0 disease correlated with OS and progression-free survival (PFS; P < .001). The most common site of recurrence was the brain. Thirty-four percent of patients recurred in the brain as their first site of failure, and 40% of patients developed brain metastases at some point in their course. In patients with nonsquamous histology and residual nodal involvement after neoadjuvant therapy, the risk of brain metastases was 53% at 3 years. Conclusion Patients treated with neoadjuvant therapy for N2-positive stage IIIA NSCLC enjoy an advantage in both OS and PFS if their lymph node status is downstaged to N0. Because brain metastases constitute the most common site of failure in these patients, future studies focusing on prophylaxis of brain metastases may improve the outcome in patients with stage IIIA NSCLC.

Object. Lung carcinoma is the leading cause of death from cancer. More than 50% of those with small cell lung cancer develop a brain metastasis. Corticosteroid agents, radiotherapy, and resection have been the mainstays of treatment. Nonetheless, median survival for patients with small cell lung carcinoma metastasis is approximately 4 to 5 months after cranial irradiation. In this study the authors examine the efficacy of gamma knife surgery for treating recurrent small cell lung carcinoma metastases to the brain following tumor growth in patients who have previously undergone radiation therapy, and they evaluate factors affecting survival. Methods. A retrospective review of 27 patients (47 recurrent small cell lung cancer brain metastases) undergoing radiosurgery was performed. Clinical and radiographic data obtained during a 14-year treatment period were collected. Multivariate analysis was utilized to determine significant prognostic factors influencing survival. The overall median survival was 18 months after the diagnosis of brain metastases. In multivariate analysis, factors significantly affecting survival included: 1) tumor volume (p = 0.0042); 2) preoperative Karnofsky Performance Scale score (p = 0.0035); and 3) time between initial lung cancer diagnosis and development of brain metastasis (p = 0.0127). Postradiosurgical imaging of the brain metastases revealed that 62% decreased, 19% remained stable, and 19% eventually increased in size. One patient later underwent a craniotomy and tumor resection for a tumor refractory to radiosurgery and radiation therapy. In three patients new brain metastases were demonstrating on follow-up imaging. Conclusions. Stereotactic radiosurgery for recurrent small cell lung carcinoma metastases provided effective local tumor control in the majority of patients. Early detection of brain metastases, aggressive treatment of systemic disease, and a therapeutic strategy including radiosurgery can extend survival.

There is a paucity of biomarkers for the prediction of intracranial (IC) outcome in immune checkpoint inhibitor (ICI)-treated non-small cell lung cancer (NSCLC) patients (pts) with brain metastases (BM). We identified 280 NSCLC pts treated with ICIs at Karolinska University Hospital, Sweden, and University Hospital of Heraklion, Greece. The inclusion criteria for response assessment were brain metastases (BM) prior to ICI administration, radiological evaluation with CT or MRI for IC response assessment, PD-1/PD-L1 inhibitors as monotherapy, and no local central nervous system (CNS) treatment modalities for ≥3 months before ICI initiation. In the IC response analysis, 33 pts were included. Non-primary (BM not present at diagnosis) BM, odds ratio (OR): 13.33 (95% CI: 1.424–124.880, p = 0.023); no previous brain radiation therapy (RT), OR: 5.49 (95% CI: 1.210–25.000, p = 0.027); and age ≥70 years, OR: 6.19 (95% CI: 1.27–30.170, p = 0.024) were associated with increased probability of IC disease progression. Two prognostic groups (immunotherapy (I-O) CNS score) were created based on the abovementioned parameters. The I-O CNS poor prognostic group B exhibited a higher probability for IC disease progression, OR: 27.50 (95% CI: 2.88–262.34, p = 0.004). Age, CNS radiotherapy before the start of ICI treatment, and primary brain metastatic disease can potentially affect the IC outcome of NSCLC pts with BM.
