Abstract
BACKGROUND The prognosis of the mediastinal fat tissue invasion in non-small cell lung cancer (NSCLC) patients has not yet been clearly defined. The present study aimed to investigate the prognostic impact of the mediastinal fat tissue invasion in NSCLC patients. METHOD We analyzed 36 patients who were found mediastinal fat tissue invasion by pathological evaluation (mediastinal fat group) and 248 patients who were classified as T4-NSCLC according to the 8th TNM classification (T4 group; invasion of other mediastinal structures in 78 patients, ipsilateral different lobe satellite pulmonary nodule in 32 patients, and tumor diameter > 7 cm in 138 patients). RESULT Resection was regarded as complete (R0) in 255 patients (89.7%). Mediastinal fat group showed significantly higher incidence of incomplete resection (R1) and more left-sided tumors than the T4 group (p = 0.01, and p = 0.002, respectively). The survival was better in T4 group than mediastinal fat group (median 57 months versus 31 months), although it was not significant (p = 0.205). Even when only N0/1 or R0 patients were analyzed, the survival was not different between two groups (p = 0.420, and p = 0.418, respectively). 5-year survival rates for T4 subcategories (invasion of other structures, ipsilateral different lobe pulmonary nodule, and tumor diameter > 7 cm) were 39.4%, 41.9%, and 50.3%, respectively (p = 0.109). Multivariate analysis showed that age (p < 0.0001), nodal status (p = 0.0003), and complete resection (p < 0.0001) were independently influenced survival. CONCLUSION There is no significant difference in the prognosis between mediastinal fat tissue invasion and T4 disease in NSCLC patients.

Abstract
Aims and Background Inoperable advanced stage lung cancer is usually treated by radiation therapy. Although a minority of patients may achieve prolonged survival with aggressive therapeutic approaches, most patients present with adverse prognostic factors that do not allow curative treatment. For these cases palliation of symptoms becomes the main treatment purpose, and short treatment schedules are commonly employed. Methods Fifty-two inoperable patients with stage IIIB or IV non-small cell lung cancer (NSCLC) were treated with a hypofractionated schedule of radiotherapy. Initially all patients received 20 Gy in five fractions, and approximately one month after irradiation completion patients underwent clinical and radiological evaluation. Those that achieved a >50% reduction in tumor load and respiratory symptoms were submitted to a second similar short course of radiotherapy. Results Thirty-three (63%) patients received only one course of radiotherapy. After the first evaluation, 19 patients (37%), all stage IIIB, fulfilled the criteria to receive a total dose of 40 Gy. Survival rates at one and two years were 33% and 0%, respectively, in the group of patients that received 20 Gy, and 52% and 21% respectively, in the group treated with 40 Gy. Two-year survival rates were 10% for stage IIIB and 0% for stage IV patients. Among the patients that were irradiated with a dose of 20 Gy, a subjective reduction of dyspnea and cough and remission of hemoptysis were observed in 97%, 82% and 80% cases, respectively. Complete remission of dyspnea and coughing was observed in 17 (89%) and 14 (74%) patients treated with two irradiation courses. Only mild toxicity was recorded. Conclusions Our treatment schedule achieved symptom control in the majority of patients. Early evaluation after 20 Gy allowed selection of responsive patients that could benefit from more prolonged treatment.

Abstract
Non-small-cell lung cancer (NSCLC) remains a leading cause of cancer mortality. The majority of patients present with advanced (stage III-IV) disease. Such patients are treated with a variety of therapies including surgery, radiation, and chemotherapy. Despite decades of work, however, overall survival in this group has been resistant to any substantial improvement. This review briefly details the evolution to the current standard of care for advanced NSCLC, advances in systemic therapy, and novel techniques (stereotactic body radiation therapy [SBRT], and transcervical extended mediastinal lymphadenectomy [TEMLA] or video-assisted mediastinal lymphadenectomy [VAMLA]) that have been used in localized NSCLC. The utility of these techniques in advanced stage therapy and potential methods of combining these novel techniques with systemic therapy to improve survival are discussed.

Abstract
PURPOSE Because T stage does not consistently reflect tumor size in non-small-cell lung cancer (NSCLC), we hypothesized that T stage may be of limited prognostic value in patients with locoregional NSCLC treated by nonsurgical means. METHODS AND MATERIALS The study population consisted of 243 patients with histologically or cytologically proven NSCLC treated in three consecutive prospective trials between 1989 and 1998. The eligibility criteria for this analysis included planned for and began treatment at 60 Gy; Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1; weight loss < or = 10%; no prior treatment; and no supraclavicular nodes, pleural effusion, or distant metastases. In the first study, 204 patients were randomized to receive conventional or accelerated radiotherapy (RT) with or without concomitant carboplatin. In the second, 15 patients were treated with concomitant cisplatin, etoposide, and RT in a single-arm study. In the third, 24 patients were treated with concomitant carboplatin, 5-fluorouracil, and RT in a dose-escalation study. RESULTS A total of 231 patients for whom the T and N stage were known met the eligibility criteria. The patient characteristics were 77% male, 64% squamous histologic features, 33% ECOG status of 0, and 69% no weight loss. The nodal status was 36% N0, 7% N1, 52% N2, and 5% N3. The estimated median survival for all patients was 1.4 years (95% confidence interval 1.2-1.6), with an estimated 10% surviving 5 years (95% confidence interval 7-15). No significant difference was found in survival among the three trials (p = 0.16). The estimated median survival time and 5-year survival rate according to T stage were as follows: T1 (n = 29), 1.6 years and 16%; T2 (n = 88), 1.3 years and 9%; T3 (n = 59), 1.4 years and 9%; and T4 (n = 55), 1.4 years and 9%. No significant trend was found in overall survival according to T stage (p = 0.85, log-rank). To test whether a significant effect of T stage on overall survival existed after adjusting for N stage, trial, ECOG status, and weight loss, a multifactor analysis using Cox proportional hazards regression analysis was carried out. There was still no significant effect of T stage on survival (p = 0.66) when all factors were taken into account. CONCLUSION Although there is some evidence that T stage is an independent prognostic factor in patients with NSCLC treated surgically, it did not appear to be of value in this series of patients treated with RT with and without concomitant chemotherapy.

Abstract
STUDY OBJECTIVES To provide a systematic overview of the literature investigating patient and tumor factors that are predictive of survival for patients with non-small cell lung cancer (NSCLC), and to analyze patterns in the design of these studies in order to highlight problematic aspects of their design and to advocate for appropriate directions of future studies. DESIGN A systematic search of the MEDLINE database and a synthesis of the identified literature. MEASUREMENTS AND RESULTS The database search (January 1990 to July 2001) was carried out combining the MeSH terms prognosis and carcinoma, nonsmall cell lung. Eight hundred eighty-seven articles met the search criteria. These studies identified 169 prognostic factors relating either to the tumor or the host. One hundred seventy-six studies reported multivariate analyses. Concerning 153 studies reporting a multivariate analysis of prognostic factors in patients with early-stage NSCLC, the median number of patients enrolled per study was 120 (range, 31 to 1,281 patients). The median number of factors reported to be significant in univariate analyses was 4 (range, 2 to 14 factors). The median number of factors reported to be significant in multivariate analyses per study was 2 (range, 0 to 6 factors). The median number of studies examining each prognostic factor was 1 (range, 1 to 105 studies). Only 6% of studies addressed clinical outcomes other than patient survival. CONCLUSIONS While the breadth of prognostic factors studied in the literature is extensive, the scope of factors evaluated in individual studies is inappropriately narrow. Individual studies are typically statistically underpowered and are remarkably heterogeneous with regard to their conclusions. Larger studies with clinically relevant modeling are required to address the usefulness of newly available prognostic factors in defining the management of patients with NSCLC.

Abstract
OBJECTIVE To quantify changes in tumor-node-metastasis (TNM) staging (numerical migration) and survival (prognostic migration) that arise when certainty criteria are applied to a patient population with non-small cell lung cancer (NSCLC) treated surgically. METHODS The population consisted of 1,844 patients with NSCLC who underwent surgery between 1993 and 1996 at hospitals participating in the Bronchogenic Carcinoma Co-operative Group of the Spanish Society of Pneumology and Thoracic Surgery (GCCB-S). For every patient, surgical-pathological TNM staging (p) was based on two classifications: initial staging by each participating GCCB-S center (pTNM-i) and a second classification bearing greater classificatory certainty (pTNM-cc) resulting from the application of stricter criteria. Numerical migration was said to have occurred in cases where the two classifications did not coincide, and the possible prognostic migration under the new staging was then assessed. RESULTS The results revealed great numerical migration in the pN0 classification (from 1,091 cases to 665). The changes did not result in prognostic migration either for the group as a whole or for pT1-2N0M0 cases. However, for pT3N0M0 cases, median survival increased by 13 months. The difference in three-year survival (S3) for pT3N0M0-i without certainty confirmation [S3 = 0.30 (95%CI 0.18-0.42), n=59] and pT3N0M0-cc [S3=0.54 (95%CI = 0.44-0.64), n = 92] was significant (log-rank, p = 0.035). Such behavior was not observed for pT1-2N0M0. CONCLUSIONS The numerical migration observed as a result of applying surgical-pathological classificatory certainty criteria is relevant but the prognostic repercussion is scarce, except in cases classified as pT3N0M0, in which a significant positive prognostic migration is observed (the "Will Rogers phenomenon").

Abstract
PURPOSE Radiation oncologists are often faced with patients with advanced non-small-cell lung cancer (NSCLC), who are not suitable candidates for state-of-the-art radical treatment, but who also are not judged to have a very short life expectancy. Some physicians treat these patients palliatively, whereas others advocate more intensive treatment. To find out if there is a substantial difference in outcome between these approaches, we performed a randomized prospective study. METHODS AND MATERIALS Between 1994 and 1998, 152 eligible patients with advanced NSCLC Stage III (n = 121) or minimal Stage IV (n = 31) were randomized to receive conventionally fractionated (cf; A: 60 Gy, 6 weeks, n = 79) or short-term treatment (PAIR; B: 32 Gy, 2 Gy b.i.d.; n = 73) of tumor and mediastinum. RESULTS One-year survival rate for all patients was 37% with no significant difference between the two treatment arms (A: 36%; B: 38%; p = 0.76). As far as can be judged from limited data available, palliation was adequate and similar for the two treatment arms. Apart from expected differences in the time course of esophagitis, acute side effects were moderate and equally distributed. No severe late effects were observed. CONCLUSIONS In the present randomized trial, survival and available data on palliation were not different after cf to 60 Gy compared to the palliative PAIR regimen. Therefore, for patients who are not suitable for radical treatment approaches, the prescription of a palliative short-term irradiation appears preferable compared to cf over several weeks.

Abstract
PURPOSE To determine whether the administration of carboplatin concurrently with radiation treatment improves survival in patients with inoperable stage III non-small-cell lung cancer. PATIENTS AND METHODS Two hundred eighty-three patients with inoperable stage III non-small-cell lung cancer were entered onto a randomized trial by the Cancer and Leukemia Group B and the Eastern Cooperative Oncology Group. Randomization was performed before initiation of any therapy. All patients received an induction chemotherapy program with vinblastine and cisplatin for 5 weeks, followed by 6,000 cGy of radiation therapy over 6 weeks. One hundred thirty-seven patients were randomized to this therapy regimen alone; 146 patients were randomized to receive carboplatin at 100 mg/m2/wk concurrent with the radiation therapy. RESULTS The complete response was 18% with concurrent carboplatin versus 10% with radiotherapy alone (P = .101). There was no difference with respect to failure-free survival (10% with carboplatin and 9% with radiotherapy alone) or overall survival (13% with carboplatin and 10% with radiotherapy alone) at 4 years. In patients not receiving carboplatin, the relapse rate was 69% within the field of radiation and 53% in the boost volume. In patients receiving carboplatin, the relapse rate was 59% within the field of radiation and 43% in the boost volume. Patients with cancers more than 70 cm2 in size had significantly poorer survival (P = .01). CONCLUSION Carboplatin at the dose and schedule used did not significantly impact on disease control or survival. The relapse rate within the chest remained more than 50%. More effective regimens will be required to impact on local disease control and survival.

Abstract
PURPOSE This study attempted to investigate, in a cohort of patients with clinical stage III initially unresectable non-small cell lung cancer (NSCLC) treated by the same induction chemotherapy regimen, the prognostic value of clinical T and N sub-groupings in order to validate the current International Staging System (ISS). PATIENTS AND METHODS All the eligible patients with stage III NSCLC (428 patients) registered in a clinical trial were included in the study investigating, after three courses of induction chemotherapy, the role, in responders, of chest irradiation in comparison to further chemotherapy. The chemotherapy regimen consisted of mitomycin C, ifosfamide and cisplatin. RESULTS Patients with ISS 1986 stage IIIA had a significantly better survival than those with stage IIIB (median survival 47 vs 36 weeks; P = 0.01). A RECPAM analysis showed that patients with T1-T2 N3 and T4 N0-1-2 stage had a more similar prognosis to those with stage IIIA. That result leads to define two new sub-groups: stage IIIlalpha (T3-T4 N0-N1; any T N2; T1-T2 N3) and IIIbeta (T3-T4 N3), with a highly significant difference in survival between them (median survival: 45 vs 29 weeks; P < 0.0001). The superiority of that new classification on the ISS documented in our series of stage III patients for discriminating survival and tumour response has to be confirmed on another series in a multivariate context. CONCLUSION For unresectable NSCLC treated by induction chemotherapy, stage III sub-classification by moving T4 N0-1 and T1-2 N3 tumours from stage IIIB to stage IIIA appeared to better correlate with prognosis. The usefulness of this new sub-division has to be tested in validation studies.

Abstract
PURPOSE The purpose of this study was to assess response, toxicity, failure patterns, and survival differences in three chemotherapy (ChT)/radiation therapy (RT) sequencing strategies for locally advanced non-small cell lung cancer (NSCLC). METHODS AND MATERIALS Five completed Radiation Therapy Oncology Group (RTOG) trials for Stage II-IIIA/B inoperable NSCLC patients employed one of the three following strategy groupings: 1) sequential ChT followed by standard RT (60 Gy in 6 weeks); 2) combined sequential and concurrent ChT and standard RT (60 Gy in 6 weeks); or 3) concurrent ChT and hyperfractionated RT (69.6 Gy in 6 weeks). All five trials required KPS > or = 70; two trials (314 patients) required <5% weight loss and three trials (147 patients) had no minimum weight loss requirement. In all five trials the ChT used cisplatin with either vinblastine or oral etoposide. Combining data for the five trials yielded an evaluable group of 461 patients. The three methods of sequencing ChT and RT were evaluated for differences in response, acute and late toxicity, patterns of failure, and survival. Acute toxicity was defined as that occurring within 90 days from the start of RT. Late toxicity was defined as that occurring after 90 days from the start of RT. Acute or late toxicity > or = grade 3 was defined as severe. Site of first failure was recorded by date. In-field failure excluded distant metastasis as a failure and included only tissue in the RT treatment field. Overall progression-free survival (PFS) was defined as survival without evidence of intra- or extrathoracic tumor or death from any cause. RESULTS Group 1 had a lower overall response rate (63%) compared to either Group 2 (77%) or Group 3 (79%), p = 0.03 and 0.003, respectively. Overall grade 4/5 acute toxicities were nearly equal between groups. The severe nonhematologic acute toxicities were significantly different by strategy group (p < 0.0001). Group 1 and 2 were not statistically different. Group 3 had significantly more patients with severe acute nonhematologic toxicity (55%) than either Group 1 (27%) or 2 (34%) with p < 0.0001 and p = 0.0005, respectively. This was due to a severe acute esophagitis rate of 34% for Group 3 versus 1.3% for Group 1 and 6% for Group 2 (p < 0.0001 for both comparisons). Overall grade 4/5 late toxicities did not differ by group. Severe late nonhematologic toxicities were different by group (p = 0.0098). Group 1 patients had significantly fewer severe late nonhematologic toxicities (14%) compared to patients in Groups 2 (26%) or 3 (28%) (p = 0.046 and 0.038, respectively). Severe late lung toxicity was 10% for Group 1 compared to 21% and 20% for Groups 2 and 3, respectively. Severe late lung toxicities differed by group (p = 0.033), but not severe late esophagitis (p = 0.077). There were no differences between the three strategy groups for patterns of first failure. The in-field failures were higher in Group 2 (71%) compared to Groups 1 (56%) and 3 (55%), p = 0.0478. Pairwise comparisons yielded p-values of 0.068 and 0.015 for Group 2 versus 1 and Group 2 versus 3, respectively. Three-year PFS was better in Group 2 (15%) and 3 (15%) compared to Group 1 (7%), but not statistically significant (p = 0.454). Similarly, in-field PFS was better in Group 2 (17%) and 3 (20%) than Group 1 (9%), but not significant (p = 0.167). There were improvements in 3-year survival for Group 2 (17%) and Group 3 (25%) compared to Group 1 (15%), but the differences were not statistically significant (p = 0.47). The same results were present for patients with less than 5% weight loss and patients with stage IIIA tumors. CONCLUSION Thus, concurrent ChT and hyperfractionated RT had a higher incidence of severe acute esophageal toxicity. Severe late lung toxicity with concurrent ChT/hyperfractionated RT, as well as with induction ChT followed by concurrent ChT/standard RT, may be greater compared to sequential ChT/RT.

Abstract
Since 1984, the Cancer and Leukemia Group B (CALGB) has focused its clinical research in stage IV non-small cell lung cancer (NSCLC) on investigations of new agents and combinations. Currently, efforts are aimed at identifying non-cisplatin-based combinations with an increased therapeutic index. In stage III disease multimodality therapies have been pursued. Dillman et al. reported a study comparing standard radiotherapy versus induction chemotherapy followed by radiotherapy in patients with unresectable stage III NSCLC. The chemotherapy-treated patients were found to benefit with a 4-month increase in median survival time compared with patients receiving radiotherapy alone (13.8 vs. 9.7 months) and an increased 3-year survival rate of 23% versus 11%. This was the first randomized cooperative group study demonstrating a survival advantage resulting from the use of induction chemotherapy in locoregionally advanced NSCLC. In a subsequent study, the administration of additional "posterior" chemotherapy was not found to be feasible because of early disease progression and toxicity, while the administration of induction chemotherapy followed by concomitant chemoradiotherapy was feasible; therefore, the latter approach was studied further in a randomized phase III setting. This study compared a standard of two cycles of cisplatin and vinblastine followed by radiotherapy with an experimental arm of cisplatin and vinblastine followed by radiotherapy and concomitant carboplatin. Accrual to this study has been completed and results are expected in the near future. In resectable stage III disease, studies have focused on the optimal sequencing of multimodality therapy. A randomized study comparing standard regional therapy with radiotherapy and surgery versus a previously piloted approach combining chemotherapy, surgery, and radiotherapy was closed prematurely due to poor accrual. The next generation of studies in stage III NSCLC will focus on the integration of new chemotherapy agents into the treatment armamentarium for NSCLC. A randomized phase II study investigating paclitaxel, gemcitabine, and vinorelbine in combination with cisplatin in the induction setting and as concomitant chemoradiotherapy has recently been activated.

Abstract
Irradiation therapy for lung cancer is mostly restricted to conventional methods. To improve therapeutic ratio, we have combined a treatment planning and a gene therapy approach. Three-dimensional conformal radiotherapy is described as carried out by methods of gene therapy for radiation protection using the manganese-superoxide-dismutase transgene delivered by inhalation gene transfer. These methods may improve therapeutic outcomes in lung cancer.

Abstract
BACKGROUND A previous pilot study from our group suggested that: (1) adoptive immunotherapy (A1) with tumor-infiltrating lymphocytes (TIL) and recombinant interleukin-2 (rIL-2) may be applied with safety to more than 80% of the patients who had surgery for Stage III nonsmall cell lung carcinoma (NSCLC); and (2) AI could be useful in patients with locally advanced disease. The present randomized study was planned to assess the efficacy of AI in the postoperative treatment of Stage II, IIIa, or IIIb NSCLC: METHODS TIL were expanded in vitro from tissue samples obtained from the surgically removed specimens of 131 patients. Eighteen cultures yielded no growth of TIL. The remaining 113 patients were stratified according to disease stage and randomized to receive AI or standard chemoradiotherapy. TIL were infused intravenously 6 to 8 weeks after surgery, rIL-2 was administered subcutaneously at escalating doses for 2 weeks, and then at reduced doses for 2 weeks and then for 2 to 3 months. RESULTS Three-year survival was significantly better (P < 0.05) for patients who underwent AI than for controls. AI was of no benefit to patients with Stage II NSCLC, potentially useful to patients with Stage IIIa NSCLC (P = 0.06), and significantly advantageous to patients with Stage IIIb (T4) NSCLC (P < 0.01). For patients with Stage III NSCLC, local relapse (but not distant relapse) was significantly reduced following AI (P < 0.05). CONCLUSIONS AI should be considered when designing future adjuvant therapy protocols for the treatment of NSCLC:

Abstract
In order to avoid overtreatment in advanced NSCLC we developed a palliative accelerated irradiation regimen (PAIR) applying a total dose of 32 Gy in 10 days with two daily fractions of 2 Gy. This paper reports on a 1-year pilot study carried out in preparation of a randomised trial. Data for the 34 patients receiving PAIR were compared to 179 conventionally irradiated historical controls selected from a pre-existing database according to identical inclusion criteria. Statistical analysis showed that PAIR patients had a significantly longer survival than controls (P = 0.0029). Median survival was 11.8 and 5.8 months, respectively, while 1-year survival was 45.6% vs. 21.2%. Compared to the subgroup of controls who had received the full planned dose of 60 Gy (n = 104) PAIR patients showed no significant difference in survival. In order to adjust for possible imbalances we used a comprehensive blinded prognostic rating design creating one score value per patient out of several known prognostic factors. After adjustment for the resulting prognostic score by means of the Cox proportional hazards model PAIR patients still showed significantly longer survival. We conclude that in advanced NSCLC survival after a palliative short-term regimen appears to be at least equivalent to that following conventional high-dose irradiation.

Abstract
UNLABELLED Concomitant chemoradiotherapy with cisplatin and combination chemotherapy in the neoadjuvant setting have both shown promising results. PURPOSE To identify a locally and systemically active concomitant chemoradiotherapy regimen incorporating high-dose cisplatin, interferon alfa-2a (IFN), fluorouracil (5-FU), hydroxyurea (HU) and radiotherapy. METHODS Phase I cohort design establishing the maximal tolerated dose (MTD) of cisplatin with and without granulocyte colony stimulating factor (GCSF). For the first six dose levels, a 4-week cycle consisted of escalating doses of cisplatin during weeks 1 and 2, IFN (week 1), and 5-FU and HU (week 2) with single daily radiation fractions of 200 cGy during days 1-5 of weeks 1-3 and no treatment in week 4. When dose-limiting neutropenia was encountered. GCSF was added during weeks 1, 3, and 4. Finally, to decrease esophagitis, the radiotherapy schedule was altered to 150 cGy twice daily during weeks 1 and 2, followed by a 2-week break (level 7). RESULTS Forty-nine patients with refractory chest malignancies were treated. The MTD of this regimen without GCSF was cisplatin 50 mg/m2 in weeks 1 and 2, IFN 5 million Units (MU)/m2 per day on days 1-5 in week 1, 5-FU 800 mg/m2 per day for 5 days by continuous infusion, and HU 500 mg every 12 h for 11 doses during week 2. The addition of GCSF during weeks 1, 3, and 4 allowed for escalation of cisplatin to 100 mg/m2 during weeks 1 and 2, with a decreased dose of IFN at 2.5 MU/m2 per day to avoid renal toxicity. Dose-limiting toxicity (DLT) included severe neutropenia, thrombocytopenia, and esophagitis in 5 of 13 patients. Increased thrombocytopenia in patients receiving GCSF was not observed. During hyperfractionated radiotherapy (level 7) chemotherapy doses were as above except for a reduction of 5-FU to 600 mg/m2 per day. While severe esophagitis was reduced, grade 4 thrombocytopenia became more prevalent and was seen in 6 of 7 patients. In-field tumor responses were observed in 17 of 28 evaluated patients with non-small-cell lung cancer. The median times to progression and survival were 4 and 6 months, respectively. When only patients with all known disease confined to the radiotherapy field were considered the corresponding times were 6 and 15 months, respectively. Most treatment failures occurred outside of the irradiated field. CONCLUSIONS (1) This intensive multimodality regimen can be given with aggressive supportive care incorporating GCSF. The recommended phase II doses for a 4-week cycle are cisplatin 50 mg/m2 week 1, and 100 mg/m2 week 2, IFN 2.5 MU, HU 500 mg every 12 h x 11 and 5-FU 800 mg/m2 per day with single fraction radiotherapy during weeks 1-3 and GCSF during weeks 1, 3, and 4. (2) GCSF can be safely administered and provides effective support of neutrophils when administered simultaneously with IFN, cisplatin, and chest radiotherapy. (3) There is synergistic renal toxicity when high doses of IFN and cisplatin are given together. (4) Hyperfractionated radiotherapy decreases the severity of esophagitis but increases thrombocytopenia. (5) Although highly toxic, response rates, time to progression and survival figures with this regimen are encouraging and support its investigation in the phase II setting.

Abstract
BACKGROUND Clinical trials of hyperfractionated radiation therapy and induction chemotherapy followed by standard radiation therapy have shown improved survival in patients with unresectable nonsmall cell lung cancer (NSCLC). Radiosensitization may improve local tumor control when chemotherapy is given concurrently with hyperfractionated radiation therapy, but also may increase toxicity. A Phase I/II trial, Radiation Therapy Oncology Group 90-15, was designed to evaluate whether this strategy could improve survival with acceptable toxicity and be part of a Phase III trial of chemoradiation sequencing. METHODS Vinblastine (5 mg/M2 weekly x 5 weeks) and cisplatin (75 mg/M2 days 1, 29, and 50) were given during twice-daily irradiation (1.2 Gy, 6 hours apart) to 69.6 Gy in 58 fractions in 6 weeks. Eligible patients had American Joint Committee on Cancer (AJCC) Stage II (unresected) or IIIA-B NSCLC and Karnofsky performance status 70 or greater; there were no weight loss restrictions. RESULTS Of 42 eligible patients, 76% had greater than 5% weight loss, 45% had T4 primary tumors, and 62% were Stage IIIB. All protocol treatment was completed in 53%. Acute toxicity was predominantly hematologic with 19 of 42 (45%) having Grade 4 toxicity or higher, three (7%) with septic death. Ten of 42 (24%) had Grade 3 or higher esophagitis. There were two (4.7%) patients with Grade 3 or higher (1 lung and 1 esophagus) and two (4.7%) with Grade 4 or higher (1 lung and 1 hematologic) late toxicities. Median survival time was 12.2 months, with an overall 1-year survival of 54%, an estimated 2 year survival of 28% and a 1-year progression free survival of 38%. CONCLUSIONS For patients with unresectable nonsmall cell lung cancer, who were not selected on the basis of weight loss, concurrent hyperfractionated irradiation and chemotherapy had more intense acute toxicity than hyperfractionation alone, but late toxicity was acceptable. One and 2-year survival rates were 54 and 28%, respectively.

Abstract
Radiation therapy alone has been 'standard' management of patients with Stage III non-small cell lung cancer for several decades. Palliative benefits are routinely achieved but significant survival benefits have not been documented. Patterns of failure in Stage III patients emphasize the need to pursue better treatment for both local macroscopic disease and distant micrometastatic sites. Improved control in both areas will be necessary to meaningfully enhance outcome for the universe of Stage III NSCLC patients. Several randomized trials show a significant survival benefit when cisplatin-containing induction chemotherapy is administered prior to locoregional treatment. In the favorable subset of Stage III patients selected for study by CALGB, the surviving fraction at 2-5 years post-therapy was > or = 2-fold larger in the chemoradiation group than in the cohort treated with radiation alone. The French trial documented a significant decrease in distant metastases rate among the chemotherapy treated patients. In all the trials where patterns of failure are discussed, local disease persistence is the overwhelming rule. Future trials must evaluate improved induction chemotherapy approaches. Stage III patients are an ethical population in which to test induction therapy with new drug combinations randomized against already 'active' regimens for comparative efficacy. End points would be initial response rates, patterns of failure, and overall survival. The feasibility of high-dose chemotherapy regimens with growth factor and hematopoietic support followed by aggressive radiation must be tested. If feasible, trials randomizing high dose versus conventional dose induction programs within the context of sequential multimodality therapy should follow. Intensified radiation approaches such as hyperfractionation or CHART should be paired with active concurrent chemotherapy following induction chemotherapy alone. Pursuit of these approaches over the next several years will hopefully produce major improvements in treatment efficacy and lead to enhanced survival expectations for the large group of patients worldwide with Stage III NSCLC.
