Abstract
AIM Positron emission tomography (PET) has been used increasingly in the staging and radiotherapy treatment planning of non-small-cell lung cancer (NSCLC). This study investigates the factors that affect the resultant size of a given image on PET. METHODS PET was used to assess the geometric characteristics of a series of radioisotope-filled, stationary spheres of known volume, surrounded by positron-emitting radioactive tracer of variable activity. The resultant PET-derived spherical volumes were then referenced to the known spherical volumes in order to illustrate quantitatively the potential influence of image threshold, tumour size and background concentration. This influence was further illustrated by clinical examples. RESULTS Considering the diameter of the spheres used in this study (10-48 mm), higher image thresholds were required for accurate rendering of the smallest spherical volumes. This inverse relationship was most consistently illustrated at the lowest background intensity ratios. CONCLUSION PET-derived volumes of NSCLC must be interpreted with caution. The data presented in this study may be used to guide the selection of appropriate image thresholds for potential clinical application.

Abstract
PURPOSE We conducted a phase III study to compare the survival impact of concurrent versus sequential treatment with radiotherapy (RT) and chemotherapy (CT) in unresectable stage III non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Patients were randomly assigned to one of the two treatment arms. In the sequential arm, patients received induction CT with cisplatin (120 mg/m2) on days 1, 29, and 57, and vinorelbine (30 mg/m2/wk) from day 1 to day 78, followed by thoracic RT at a dose of 66 Gy in 33 fractions (2 Gy per fraction and 5 fractions per week). In the concurrent arm, the same RT was started on day 1 with two concurrent cycles of cisplatin 20 mg/m2/d and etoposide 50 mg/m2/d (days 1 to 5 and days 29 to 33); patients then received consolidation therapy with cisplatin 80 mg/m2 on days 78 and 106 and vinorelbine 30 mg/m2/wk from days 78 to 127. RESULTS Two hundred five patients were randomly assigned. Pretreatment characteristics were well balanced between the two arms. There were six toxic deaths in the sequential arm and 10 in the concurrent arm. Median survival was 14.5 months in the sequential arm and 16.3 months in the concurrent arm (log-rank test P = .24). Two-, 3-, and 4-year survival rates were better in the concurrent arm (39%, 25%, and 21%, respectively) than in the sequential arm (26%, 19%, and 14%, respectively). Esophageal toxicity was significantly more frequent in the concurrent arm than in the sequential arm (32% v 3%). CONCLUSION Although not statistically significant, clinically important differences in the median, 2-, 3-, and 4-year survival rates were observed, with a trend in favor of concurrent chemoradiation therapy, suggesting that is the optimal strategy for patients with locally advanced NSCLC.

Abstract
AIMS To describe the toxicity and response seen in patients receiving moderate-dose radiation therapy with concurrent weekly low-dose gemcitabine in the management of locally advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Eighteen patients with confirmed NSCLC were enrolled over a 17-month period from August 2000 until January 2002. All had localised disease but were considered unsuitable for curative therapy. Radiation therapy was given to a dose of 30 Gy in 15 fractions over 3 weeks. Gemcitabine was given weekly before and within 3 h of fractions 1, 6 and 11. The study was designed as a dose-escalation study, commencing at 100 mg/m2 and increasing at levels of 50 mg/m2, until the maximum tolerated dose (MTD) was reached. RESULTS The MTD was regarded as being 150 mg/m2. The major acute toxicity observed was oesophagitis. Skin reactions were also reported. The overall response rate in all patients was 88%, with 44% achieving a complete response. CONCLUSION The combination of gemcitabine and moderate-dose radiation therapy is feasible, and offers low toxicity and excellent response rates in patients with localised NSCLC not suitable for high-dose therapy.

Abstract
Central nervous system (CNS) metastasis is a significant problem for many patients with non-small cell lung cancer (NSCLC). The earlier data reported a high incidence of CNS metastasis in patients with locally advanced NSCLC who were treated with radiotherapy alone. However, poor control of both thoracic and extracranial systemic disease dominated the results of the early trials. The risk for CNS metastasis as the first site of failure remains a significant concern for patients who have completed modern combined modality therapy. With improvements in the treatment of thoracic and systemic disease, there is renewed interest in prophylactic cranial irradiation (PCI). The results from the Radiation Therapy Oncology Group (RTOG) trial of PCI to prevent CNS relapse in patients with locally advanced NSCLC are anticipated.

Abstract
Background Combined chemoradiotherapy (CRT) is the treatment of choice for stage III NSCLC. Gemcitabine (G) is a novel deoxycitidine analogue that has been proven to be a potent radiosensitizer. Twenty-two consecutive patients were treated with concurrent CRT to demonstrate the tolerability and efficacy of low dose G given weekly as radiosensitizer in stage III NSCLC. Methods Patients with KPS ≥70, adequate bone marrow reserve, with no prior radiotherapy (RT) and surgery were included. Eighteen patients had received prior induction chemotherapy (CT). G (75 mg/m2/week) was infused over 1 hour for 6 weeks. Thoracic RT was given two hours later over 6 weeks at 1.8 Gy/day fractions (total dose of 61.2 Gy). Pulmonary toxicity was evaluated with computed tomography scans in 6 weeks. Results Median age was 60 years (range, 48–75), median follow-up was 15 months (range, 2–40). Sixty-eight percent of patients were male and median KPS score was 90. Conformal 3D-RT planning was used in 64% of patients. G was given for a median of 5 weeks (range 1–9). Twelve patients (54.6%) received all planned CT. G was stopped because of intolerance in 6 and death in 2 patients. Seven patients (31.8%) had radiation pneumonitis. Twenty patients were evaluated for overall response, 1 patient (4.5%) had clinical CR, 81.8% had PR while 9.5% had SD. Median overall survival (OS) was 14 ± 5 months (95% CI 3–25). One- and 2-year OS rates were 55% and 38%. Sixteen patients died of disease-related events (6 with progression of primary tumor, 8 due to metastatic disease), 2 patients died of other causes. One- and 2-year progression-free survival and local control rates were 56%, 27% and 79%, 51%, respectively. Conclusion G might be used as radiosensitizer for patients with stage III NSCLC who could not receive full doses CT with concurrent RT.

Abstract
Combined chemoradiotherapy (CTRT) is intended to reduce the risk of local regional recurrence and distant relapse in patients with early stage non-small cell lung cancer (NSCLC). Sequential CTRT allows full doses of each modality while avoiding the additive toxicity that occurs with concurrent therapy. This review will encompass studies in the three main settings where sequential CTRT has been applied in early stage NSCLC: as adjuvant therapy after resection, as neoadjuvant chemotherapy and surgery followed by radiotherapy, and in unresectable stage III disease.

Abstract
BACKGROUND We report a study of induction chemotherapy followed by concurrent chemoradiotherapy for stage IIIA/IIIB non-small cell lung cancer. METHODS Patients received two cycles of induction chemotherapy with cisplatin 100 mg/m(2) on day 1 and gemcitabine 1000 mg/m(2) on days 1, 8, and 15 of a 28-day cycle. If the disease was resectable [corrected] surgery was followed with two further cycles. If unresectable, patients received cisplatin 100 mg/m(2) day 1, 29 with 5-fluorouracil 1000 mg/m(2) per 24 h continuous infusion for 96 h on days 2-5 and days 30-33 of the radiotherapy administration. Radiation therapy consisted of 63 Gy, 35 fractions, 7 weeks. RESULTS Of 48 patients, 40% had a partial response to induction chemotherapy. Four of eleven patients with stage IIIA tumours had resectable disease. The remaining seven patients plus 37 with stage IIIB disease had chemoradiotherapy. Response at the completion of all therapy was 62% (IIIA 73%, IIIB 59%). For all patients the median survival was 15.3 months: 1 year and 3 years, 58% and 25%, respectively. Those with IIIB disease responding to induction chemotherapy had significantly superior survival to those that did not respond (37 months vs 11 months; P = 0.005). This remained significant from a landmark at 8 weeks after the start of treatment (P = 0.01). CONCLUSION These results are equivalent to other studies using induction chemotherapy prior to concurrent chemoradiotherapy. Response to induction chemotherapy may have major prognostic significance.

Abstract
PURPOSE Gemcitabine-platinum combination activity has been clearly established in a number of phase II studies. It has also been compared against other combinations in many phase III trials. It is generally believed that all such regimens have an equivalent impact on survival. This meta-analysis aims to quantify the treatment effect of gemcitabine plus a platinum agent in the treatment of advanced NSCLC and compare the combination to other regimens used globally. DESIGN Data from a total of 4556 patients from 13 randomized trials investigating gemcitabine in combination with a platinum agent versus any other platinum-containing regimen were included in a meta-analysis of time-to-event outcomes. RESULTS A significant reduction in overall mortality in favor of gemcitabine-platinum regimens was observed, hazard ratio (HR) 0.90 (95% CI: 0.84-0.96) with an absolute benefit at 1 year of 3.9%. Median survival was 9.0 months for the gemcitabine-platinum regimens and 8.2 months for the comparator regimens. Sub-group analysis of the first- and second-generation platinum-based comparator regimens also indicated a significant benefit for gemcitabine-platinum regimens, HR 0.84 (CI: 0.71-0.9985). Analysis of third-generation agent plus platinum regimens showed a non-significant trend favoring gemcitabine-platinum regimens, HR 0.93 (CI: 0.86-1.01). There was a significant decrease in the risk of disease progression in favor of gemcitabine-platinum regimens, HR 0.88 (CI: 0.82-0.93). An absolute benefit of 4.2% at 1 year was estimated. Median progression-free survival was 5.1 months for gemcitabine-platinum regimens compared with 4.4 months for the comparator regimens. Sub-group analysis indicated a statistically significant progression-free survival benefit for patients assigned to gemcitabine-platinum treatment compared to first- and second-generation platinum regimens, HR 0.85 (CI: 0.77-0.94), and third-generation agent plus platinum regimens, HR 0.89 (CI: 0.82-0.96).

Abstract
BACKGROUND The purpose of this study was to evaluate whether radiotherapy with carboplatin would result in longer survival than radiotherapy alone in elderly patients with unresectable stage III non-small cell lung cancer (NSCLC). METHODS Eligible patients were 71 years of age or older with unresectable stage III NSCLC. Patients were randomly assigned to the radiotherapy alone (RT) arm, irradiation with 60 Gy; or the chemoradiotherapy (CRT) arm, the same radiotherapy and additional concurrent use of carboplatin 30 mg/m(2) per fraction up to the first 20 fractions. RESULTS This study was terminated early when 46 patients were registered from November 1999 to February 2001. Four patients (one in the RT arm, three in the CRT arm) were considered to have died due to treatment-related causes. The JCOG Radiotherapy Committee assessed these treatment-related deaths (TRDs) and the compliance with radiotherapy in this trial. They found that 60% of the cases corresponded to protocol deviation and 7% were protocol violation in dose constraint to the normal lung, two of whom died due to radiation pneumonitis. As to the effectiveness for the 46 patients enrolled, the median survival time was 428 days [95% confidence interval (CI) = 212-680 days] in the RT arm versus 554 days (95% CI = 331 to not estimable) in the CRT arm. CONCLUSIONS Due to the early termination of this study, the effectiveness of concurrent use of carboplatin remains unclear. We re-planned and started a study with an active quality control program which was developed by the JCOG Radiotherapy Committee.

Abstract
AIMS The debate on the funding and availability of cytotoxic drugs raises questions about the contribution of curative or adjuvant cytotoxic chemotherapy to survival in adult cancer patients. MATERIALS AND METHODS We undertook a literature search for randomised clinical trials reporting a 5-year survival benefit attributable solely to cytotoxic chemotherapy in adult malignancies. The total number of newly diagnosed cancer patients for 22 major adult malignancies was determined from cancer registry data in Australia and from the Surveillance Epidemiology and End Results data in the USA for 1998. For each malignancy, the absolute number to benefit was the product of (a) the total number of persons with that malignancy; (b) the proportion or subgroup(s) of that malignancy showing a benefit; and (c) the percentage increase in 5-year survival due solely to cytotoxic chemotherapy. The overall contribution was the sum total of the absolute numbers showing a 5-year survival benefit expressed as a percentage of the total number for the 22 malignancies. RESULTS The overall contribution of curative and adjuvant cytotoxic chemotherapy to 5-year survival in adults was estimated to be 2.3% in Australia and 2.1% in the USA. CONCLUSION As the 5-year relative survival rate for cancer in Australia is now over 60%, it is clear that cytotoxic chemotherapy only makes a minor contribution to cancer survival. To justify the continued funding and availability of drugs used in cytotoxic chemotherapy, a rigorous evaluation of the cost-effectiveness and impact on quality of life is urgently required.

Abstract
PURPOSE The superiority of chemoradiotherapy (CRT) over radiation alone in locally advanced non-small cell lung cancer (NSCLC) has been proven, but the relative merits of a concurrent schedule versus their sequential administration are less clear. This study compared the safety and efficacy of concurrent and sequential CRT, with chemotherapy (CT) consisting of a cisplatin and vinorelbine regimen, in patients with locally advanced NSCLC. PATIENTS AND METHODS One hundred and two previously untreated patients (aged 42-75 years) with locally advanced, stage IIIA (n = 15) or stage IIIB (n = 87) NSCLC were entered into the study. The CT schedule consisted of up to four cycles of cisplatin 80 mg/m(2) on day 1, and vinorelbine 25 mg/m(2) at the first and fourth cycles (12.5 mg/m(2) during the 2nd/3rd cycles) on days 1, 8, 15 of a 28-day cycle. Radiotherapy (RT) was prescribed at a dose of 60 Gy/30 fractions, given as five fractions per week for 6 weeks. In the concurrent arm (arm A), RT was started on day 4 of cycle 2; whilst in the sequential arm (arm B), RT started within 2 weeks after completion of CT. Fifty-two patients were randomized to concurrent treatment and 50 to the sequential schedule. RESULTS Overall survival was significantly longer in arm A (median survival 16.6 months) versus arm B (median survival 12.9 months) (P = 0.023 by means of log-rank test; hazard ratio HR = 0.61, 95% CI of HR (0.39-0.93)), and time to progression (TTP) was also significantly longer in arm A (median time to progression 11.9 months) versus arm B (median time to progression 8.5 months) (P = 0.024 by means of log-rank test; HR = 0.62, 95% CI of HR (0.38-0.93)). Ninety-eight patients were evaluable for response and 101 for toxicity. The overall response rate was significantly higher in arm A, 80% (with 21% complete response (CR)) compared with 47% (with 17% CR) in arm B (P = 0.001 by means of chi(2)-test). WHO grade 3 or 4 toxicity was more frequent in arm A than in arm B, with a significantly greater incidence of leucopenia (53% versus 19%, P = 0.009 by means of chi(2) test) and nausea/vomiting (39% versus 15%, P = 0.044 by means of chi(2) test). There were no treatment related deaths. CONCLUSION In this study population, concurrent CRT demonstrated significant benefit in terms of response rate, overall survival and time to progression over sequential CRT. The concurrent CRT schedule was associated with higher toxicity; however, the adverse event profile was acceptable in both arms.

Abstract
PURPOSE To evaluate the efficacy of concurrent radiochemotherapy in patients with stage III non-small cell lung cancer (NSCLC), and to examine the effect of hemoglobin levels on survival of those patients. The negative impact of anemia on survival has been noticed for other cancer sites including the head and neck, and the uterine cervix, but it has been rarely described in NSCLC cancer patients treated with radiotherapy. METHODS From April 1995 through March 2002, 56 patients with inoperable stage III non-small lung cancer were treated with radiotherapy consisting of 60 Gy (50 Gy+10 Gy boost) given in 30 fractions of 2 Gy daily, 5 days a week, over a period of 6 weeks, and concurrent low-dose daily chemotherapy (CHT) consisting of 6 mg/m(2) of cisplatin given Mondays-Fridays during weeks 1-2 and 5-6. All patients had stage III disease and ages ranged from 39 to 81 years old (median 63.9 years). RESULTS The 2-year and 3-year survival rates were 34% and 16%, respectively. Patients with a pretreatment hemoglobin level superior or equal to 11.6 g/dl had a 2-year survival rate of 52% as compared to 15.5% for patients with a pretreatment hemoglobin level inferior to 11.6 g/dl (p=0.0075). Patients with higher KI (>70%) showed better survival rates than those with lower KI. Surprisingly, patients in stage IIIA did not survive significantly longer than those in stage IIIB. Hematological toxicity (grade > or =2) prevailed (25%), followed by esophageal (5.4%) and bronchopulmonary (2%) toxicity. Only three patients experienced acute grade 3 hematological toxicity. Because of acute toxic effects, irradiation was interrupted in 8 patients (14.3%) for 7-13 days (median 7.5 days). Late high-grade (> or =3) toxicity was not found. No grade 4 toxicity or treatment-related deaths were observed during this study. CONCLUSION Our data show that concurrent radiotherapy with daily low dose cisplatin is well tolerated, and shows survival rates comparable to more aggressive treatment regimens. A combination of this chemotherapy with accelerated hyperfractionated radiotherapy might improve the results in the future. Furthermore, we could show that the hemoglobin levels prior to therapy have an influence on the prognosis, where lower levels were associated with worse outcome. Further trials should consider supplementation with erythropoietin.

Abstract
The combination of radiotherapy and chemotherapy (RCT) has improved the treatment results of patients with inoperable stage-III NSCLC in comparison to irradiation alone and is seen as the standard treatment at present. Concomitant RCT was significantly superior to sequential RCT in three of four studies, so that the simultaneous therapy sequence is seen today as the best modality. Nevertheless, the results, with median survival times of 15-18 months and a 5-year survival rate between 10 and 20%, are still not satisfactory so that further possibilities of optimisation are being looked for: --Can the results of concomitant RCT be improved by an induction chemotherapy or subsequent chemotherapy? --Is there an additional benefit of operative measures for tumours which through the application of RCT get operable? --What is the additional benefit of biological response modifiers applied together with RCT? --Is there a place for RCT of elderly patients or patients in poor general condition? The rationale as well as the initial results shall be discussed in this overview.

Abstract
Purpose To prospectively determine the maximum-tolerated dose of accelerated hyperfractionated conformal radiotherapy (RT; 1.6 Gy bid) for unresectable locally advanced lung cancer (IIB to IIIA/B) following induction carboplatin/paclitaxel (C/T) or carboplatin/vinorelbine (C/N). Methods Induction chemotherapy, C/T or C/N, was followed by escalating doses of conformally-planned RT (73.6 to 86.4 Gy in 6.4-Gy increments). Concurrent boost methods delivered 1.6 and 1.25 Gy bid to the gross and clinical target volumes, respectively. Results Between November 1997 and February 2002, 44 patients were enrolled (median age, 59 years; 59% male; stage III, 98%; median tumor size, 4 cm). Thirty-nine patients completed induction chemotherapy: 19 had a partial response, seven progressed, 15 had no response, and three were not assessable. Chemotherapy-associated toxicities were similar in the two chemotherapy groups. The incidence of grade ≥ 3 RT-induced toxicity was 1/13, 2/14, and 4/12 at 73.6, 80, and 86.4 Gy, respectively, thus defining the maximum tolerated dose at ≈80 Gy. Toxicities were in both lung and esophagus and were similar in the two chemotherapy arms. With a median followup of 34 months in the survivors, the actuarial 2-year survival was 47%, the median survival was 18 months. Fifteen patients had tumor relapse: 5 local failures in the high-dose volume, 2 regional failures outside of the high-dose volume, and 8 distant metastases. Conclusion High-dose conformal twice-daily radiation therapy to approximately 80 Gy appears tolerable in well-selected patients with unresectable lung cancer following either C/T or C/N. Dose-limiting toxicities are mainly pulmonary and esophageal.

Abstract
BACKGROUND The Radiation Therapy Oncology Group (RTOG), a National Cancer Institute sponsored cancer clinical trials research cooperative, has recently formed an Outcomes Committee to assess a comprehensive array of clinical trial endpoints and factors impacting the net effect of therapy. METHODS To study outcomes in a consistent, comprehensive and coordinated manner, the RTOG Outcomes Committee developed a model to assess clinical, humanistic, and economic outcomes important in clinical trials. RESULTS This paper reviews how the RTOG incorporates outcomes research into cancer clinical trials, and demonstrates utilization of the RTOG Outcomes Model to test hypotheses related to non-small-cell lung cancer (NSCLC). In this example, the clinical component of the model indicates that the addition of chemotherapy to radiotherapy (RT) improves survival but increases the risk of toxicity. The humanistic component indicates that esophagitis is the symptom impacting quality of life the greatest and may outweigh the benefits in elderly (> or =70 years) patients. The economic component of the model indicates that accounting for quality-adjusted survival, concurrent chemoRT for the treatment of NSCLC is within the range of economically acceptable recommendations. CONCLUSION The RTOG Outcomes Model guides a comprehensive program of research that systematically measures a triad of endpoints considered important to clinical trials research.

Abstract
PURPOSE The aim of this study was to determine the role of chemotherapy dose intensity in patients with initially unresectable non-metastatic non-small-cell lung cancer (NSCLC), with survival as primary end point, by testing two different regimens as induction chemotherapy followed by thoracic irradiation. PATIENTS AND METHODS Patients had pathologically proven NSCLC, an initially unresectable non-metastatic tumour without homolateral malignant pleural effusion, no prior history of malignancy and had received no prior therapy. Treatment was randomised for chemotherapy between three courses of MIP (mitomycin C 6 mg/m2; ifosfamide 3 g/m2; cisplatin 50 mg/m2) or SuperMIP (mitomycin C 6 mg/m2; ifosfamide 4.5 g/m2; cisplatin 60 mg/m2, carboplatine 200 mg/m2), followed by chest irradiation (60 Gy; five times per week, for 6 weeks). If the tumour became resectable after chemotherapy, surgery was performed, followed by mediastinal irradiation. RESULTS A total of 351 patients were eligible: 176 in the MIP arm and 175 in the SuperMIP arm, with 43% and 51% stages IIIA and IIIB, respectively. There was a significantly higher objective response rate with SuperMIP (46%) compared with MIP (35%) (P=0.03) [95% confidence interval (CI) for the difference between the response rates, 1% to 22%]. After induction chemotherapy, surgery was performed in 54 (15%) patients (27 per arm) and chest irradiation in 203 (57%) patients (102 in the MIP arm and 101 in the SuperMIP). In terms of survival, there was no statistically significant difference between the two study arms (P=0.16), with median survival times of, for MIP and SuperMIP, respectively, 12.5 (95% CI 10.1-14.9) and 11.2 (95% CI 9.7-12.8) months. Haematological toxicity and dosage reductions were higher with SuperMIP, which was nevertheless associated with a significantly increased absolute dose intensity. CONCLUSIONS High dose-intensity induction chemotherapy does not improve survival in initially unresectable non metastatic NSCLC.

Abstract
We conducted a phase I/II study investigating synchronous chemoradiotherapy with mitomycin C and infusional 5-fluorouracil (5-FU) in muscle invasive bladder cancer. Early dose escalation results were previously published. We report the long-term toxicity and efficacy results with the optimised regimen. Patients with muscle invasive bladder cancer with glomerular filtration rate >25 ml min(-1) were eligible. Mitomycin (12 mg m(-2) on day 1 only) and infusional 5-FU (500 mg m(-2) day(-1)) for 5 days were administered during weeks 1 and 4 of radiotherapy of 55 Gy in 20 fractions. A total of 41 patients were enrolled, median age was 68 years, 33 were male and eight female patients. Out of the 41 patients, 20 (49%) had hydronephrosis at presentation and 25 (62%) had T3b or T4 disease. Four patients experienced Grade III thrombocytopenia and three patients had Grade III neutropenia. There were no episodes of febrile neutropenia. Four patients experienced Grade III diarrhoea and 1 Grade III urgency and dysuria. Six patients did not undergo cystoscopic evaluation due to early metastatic spread although there was no clinical suggestion of bladder failure. In all, out of 35 evaluable patients, 25 (71%) had macroscopic complete response at 3-month cystoscopy, and biopsy confirmed in 24 out of 25. A total of 16 (39%) patients remain alive with a median follow-up of 50.7 (range 23.5-68.8) months, 14 with a functioning bladder with no reported long-term treatment-related bladder or bowel toxicity. Five out of 41 patients have undergone salvage cystectomy: two for persistent CIS, two T1 and one muscle invasive recurrence. Four patients have received intravesical chemotherapy, of whom two remain alive with a functioning bladder. Overall 12-, 24- and 60-month (m) survival rates were 68, 49 and 36%. Local and distant progression free rates were 82 and 86% at 12-m and 79 and 75% at 24-m. Organ preservation using multimodality therapy is feasible and safe, even in patients with poor renal reserve, and does not compromise salvage therapies. A national phase III trial BC2001 (www.bc2001.org.uk) exploring the effects of synchronous chemoradiotherapy with this regimen is currently recruiting.

Abstract
The position for induction chemotherapy has shifted somewhat in the past few years. This approach has the ability to reduce distant failure and is relatively easy to administer. There are patients who would benefit from and could be offered induction chemotherapy--specifically, those who would not tolerate concurrent chemoradiotherapy or those who might benefit from more intensive therapy combing induction and concurrent strategies. The latter platform, however, should be undertaken with caution, ideally in a clinical trial setting.

Abstract
Much work has been done regarding QOL in lung cancer trials. There are now several validated QOL instruments, particularly for patients with lung cancer. Past accomplishments include key trials demonstrating a benefit of chemotherapy or radiation in patients with advanced NSCLC not only regarding traditional endpoints but also by improving palliation and aspects of QOL such as pain and dyspnea. More recently, studies have emerged that incorporate QOL in patients with locally advanced disease. Key challenges relate to the optimal design and successful completion of these QOL studies. Missing data remains a key problem in many QOL studies, particularly in lung cancer trials. Future studies should focus on incorporating QOL into phase III studies with clear hypotheses that can ultimately lead to clinically meaningful interventions.

Abstract
PURPOSE Recent studies have reported improved survival with concurrent chemoradiotherapy (ChRT) for inoperable non-small-cell lung cancer (NSCLC). ChRT includes the delivery of low-dose chemotherapy given daily during radiotherapy (RT) or higher doses administered weekly. It remains unknown whether a difference in efficacy or toxicity exists between these approaches. A systematic review was performed to compare the efficacy and toxicity of weekly vs. daily ChRT. METHODS AND MATERIALS The results from randomized studies comparing ChRT to RT for NSCLC were pooled using meta-analyses. The relative risk (RR) of death at 1, 2, and 3 years and of acute esophagitis, pneumonitis, or neutropenia (World Health Organization Grade 3 or greater) were determined. RESULTS Ten studies involving 1802 patients were included. No significant difference in mortality or toxicity was observed between the weekly and daily regimens: RR of death at 2 years-weekly 0.93, 95% confidence interval [CI] 0.87-0.99; daily 0.92, 95% CI 0.85-1.00; RR of death at 3 years-weekly 0.93, 95% CI 0.89-0.98; daily 0.90, 95% CI 0.81-1.01; RR of esophagitis-weekly 2.07, 95% CI 0.96-4.46; daily 1.70, 95% CI 1.17-2.48; RR of pneumonitis-weekly 1.52, 95% CI 0.93-2.48; daily 1.17, 95% CI 0.65-2.09; and RR of neutropenia-weekly 8.57, 95% CI 3.75-19.58; daily 11.93, 95% CI 1.55-92.12. CONCLUSION No statistically significant difference in efficacy or acute toxicity was observed to suggest the superiority of daily vs. weekly ChRT regimens for NSCLC.

Abstract
Preoperative chemotherapy in patients with stage III non-small-cell lung cancer (NSCLC) remains controversial. Phase II trials utilizing preoperative chemotherapy in selected patients have achieved complete resection rates of 50%-70% with 3-5 year failure-free survival rates of 15%-33%. Between October 1992 and November 1994, 57 adults (50 of whom were evaluable) with surgically staged IIIA NSCLC and pathologically documented ipsilateral mediastinal nodal involvement (N2) were enrolled in a Cancer and Leukemia Group B randomized trial. Preoperative therapy was thought to be critical to facilitating surgical resectability. For patients randomized to the radiotherapy/surgery/radiotherapy (RSR) arm (n = 24), treatment consisted of preoperative radiation therapy (RT) at 40 Gy, surgery, and then additional RT at 14-20 Gy. For patients randomized to the chemotherapy/surgery/chemotherapy/radiotherapy (CSCR) arm (n = 26), treatment consisted of 2 cycles of cisplatin/etoposide with filgrastim support (PE) followed by surgery, 2 more cycles of PE, then RT 54-60 Gy. The total dose of RT on either arm was 54 Gy if completely resected or 60 Gy if incompletely resected or unresected. Clinical characteristics were well balanced between the two arms. Thoracotomy was performed in 42 patients (84%), 28 (67%) of whom had complete resection. The median failure-free and overall survival rates were 12 months (95% confidence interval [CI], 9-23 months) and 23 months (95% CI, 19 months-infinity) for the RSR arm and 11 months (95% CI, 5-20 months) and 18 months (95% CI, 12-32 months) for the CSCR arm. The rates of overall and complete surgical resection, downstaging of nodal involvement, and failure-free (P = 0.92) and overall survival (P = 0.41) did not differ between the two treatment arms. Moreover, in this trial, the chemotherapy regimen was sufficiently toxic to have had a lower completion rate of prescribed therapy in the CSCR arm than in the RSR arm.

Abstract
Radiation therapy used as a single modality in the treatment of locally advanced non-small-cell lung cancer is potentially curative, but long-term survival rates are disappointing due to both locoregional and distant failures. The trials of the Radiation Therapy Oncology Group (RTOG) have been instrumental in defining the optimal management of this disease. The conclusions and questions posed by the RTOG are discussed in this review. The conclusions of this review include the following: chemotherapy combined with radiation therapy improves survival in patients with good performance, with increased toxicity; concurrent chemoradiation is superior to sequential chemoradiation. Questions remain regarding the value of the addition of induction or consolidation chemotherapy to concurrent chemoradiation, the value of three-dimensional conformal radiation therapy, the role of altered fractionation regimens in combination with chemotherapy, the optimal chemotherapeutic regimen, and the role of novel biologic agents.

Abstract
Many patients who receive a diagnosis of non-small cell lung cancer (NSCLC) have locally advanced disease at initial presentation. Historically, these patients were treated with primary thoracic radiation therapy and had poor long-term survival rates, secondary to both progression of local disease and development of distant metastases. With the goal of improving clinical outcomes, multiple concepts of combined-modality therapy for locally advanced NSCLC have been investigated. The rationale for using chemotherapy in the induction regimen is to eliminate subclinical metastatic disease while improving local control. The optimal treatment of locally advanced NSCLC continues to evolve, but combined-modality therapy has led to improved survival rates compared to treatment with radiation alone and has become the new standard of care. This report reviews the major trials that have investigated various combinations of surgery, radiation therapy, and chemotherapy in the treatment of locally advanced NSCLC.

Abstract
PURPOSE To report the incidence of late complications in long-term survivors of very-high-dose thoracic radiotherapy (RT) treated on a prospective clinical trial. METHODS AND MATERIALS Patients with locally advanced or medically inoperable non-small-cell lung cancer received three-dimensional conformal RT to the primary tumor and radiographically involved lymph nodes to a dose of 73.6 Gy at 1.6 Gy twice daily. If the plasma transforming growth factor-beta1 (TGF-beta1) level was normal after 73.6 Gy, additional twice-daily RT was delivered to successively higher total doses until the maximal tolerated dose was reached. Patients within a given dose level were followed for 6 months before escalation to the next dose level was permitted. Late complications were defined according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria. RESULTS Thirty-eight patients were enrolled between 1996 and 1999. Twenty-four patients were not eligible for radiation dose escalation beyond 73.6 Gy because of persistently abnormal TGF-beta1 levels. Fourteen patients received dose escalation (80 Gy in 8; 86.4 Gy in 6). Grade 3 or greater late complications occurred in 4 of 24, 1 of 8, and 2 of 6 patients treated to 73.6, 80, and 86.4 Gy, respectively. The corresponding patient numbers with late Grade 4-5 toxicity were 3 of 24, 0 of 6, and 0 of 8. Overall, 7 (18%) of the 38 patients developed Grade 3-5 late toxicity. Nonpulmonary complications predominated (4 of 7). Five (71%) of seven serious complications developed within 11 months after RT; however, the remaining two complications (29%) occurred very late (at 43 and 62 months). The 5-year actuarial risk of late Grade 3-5 complications was 33%. CONCLUSION Long-term survivors of very-high-dose RT for non-small-cell lung cancer have a significant risk of severe treatment-related complications. At these high dose levels, the predominant toxicity may no longer be pulmonary. All Grade 4-5 complications occurred in patients whose dose was limited to 73.6 Gy because of a persistently elevated TGF-beta1. Thus, persistently elevated plasma TGF-beta1 levels toward the end of RT may identify patients at greatest risk of severe complications.

Abstract
BACKGROUND The objective of this trial was to evaluate the activity and safety of one of the newer platinum-based doublets as a neoadjuvant regimen in patients with unresectable Stage IIIA-bulky N2 and Stage IIIB nonsmall cell lung carcinoma (NSCLC). METHODS From June 1996 to April 2000, 129 consecutive patients with locally advanced NSCLC were treated with gemcitabine, 1000 mg/m(2) on Days 1 and 8 and cisplatin, 70 mg/m(2) on Day 2 (GC) of a 21-day treatment cycle, for 4 cycles, as part of a combined-modality approach. RESULTS After induction chemotherapy, 80 patients (62%; 95% confidence interval, 53.6-70.4%) achieved a partial response, 43 patients (33%) had stable disease, and 6 patients (5%) had disease progression during chemotherapy. Forty patients (31%), were considered resectable and underwent thoracotomy. Complete resectability was obtained in 38 patients (29%), with 2% of patients achieving a pathologic complete response. After surgery, 9 patients with Mountain Classification Stage IIIA NSCLC and 9 patients with Stage IIIB NSCLC received definitive adjuvant radiotherapy. Forty-six of 52 patients with Stage IIIB disease and 24 of 37 patients with Stage IIIA disease who were not considered suitable for surgery received definitive radiotherapy. The median time to disease progression was 11.4 months, the median survival was 19.4 months (range, 1.2-55.2 + months), and the 1-year survival rate was 74%. The lungs (33%) and the brain (21%) were the main sites of recurrence. Major toxicity was comprised of Grade 3-4 thrombocytopenia, which occurred in 34 patients (27%). CONCLUSIONS GC administered according to a 3-week schedule was a highly active and safe regimen in patients with primary, unresectable, locally advanced NSCLC.

Abstract
CD22 is a membrane glycophosphoprotein found on nearly all healthy B-lymphocytes and most B-cell lymphomas. Recent in vitro studies have identified several anti-CD22 monoclonal antibodies (mAbs) that block the interaction of CD22 with its ligand. One of these mAbs, HB22.7, has been shown to effectively induce apoptosis in several B-cell lymphoma cell lines. Lymphoma xenograft studies with Raji-xenograft mice were used to assess the toxicity and efficacy of HB22.7 alone and with combined modality immunotherapy (CMIT) with yttrium (90)Y-DOTA-peptide-Lym-1 radioimmunotherapy (RIT). The effect of the sequence of these agents on the combined treatment was assessed by administering HB22.7 24 hours before, simultaneously with, or 24 hours after RIT. Within the groups treated with RIT alone or with RIT and HB22.7 (CMIT), the reduction in tumor volume was the greatest when HB22.7 was administered simultaneously with and 24 hours after RIT, and in the RIT treatment groups, this translated into the greatest overall response and survival, respectively. Overall survival rates at the end of the 84-day CMIT trial were 67% and 50% in the groups treated with HB22.7 simultaneously and 24 hours after RIT, respectively. This compared favorably with the untreated and the RIT alone groups, which had survival rates of 38% and 43% at the end of the trial. Surprisingly, when compared with untreated controls and all other treatment groups, the greatest cure and overall survival rates were observed in the group treated with HB22.7 alone, with 47% cured and 76% surviving at the end of the 84-day trial. RIT clearance was not affected by treatment with HB22.7. When compared with RIT alone, there was no significant additional hematologic (white blood cell, red blood cell, or platelet count) toxicity when HB22.7 was added to RIT. Nonhematologic toxicity (assessed as change in body weight) was also unchanged when HB22.7 was added to RIT. Thus the anti-CD22 ligand-blocking antibody HB22.7 has independent lymphomacidal properties and augments the efficacy of (90)Y-DOTA-peptide-Lym-1 in lymphoma xenografts without significant toxicity.

Abstract
OBJECTIVE To analyze the results of radiotherapy for non-small cell lung cancer and identify the clinical and therapeutic variables that might influence prognosis. PATIENTS AND METHODS In a population base of 109 patients, 87 met the enrollment criteria. The patients received thoracic radiotherapy over the macroscopic tumor volume and lymph drainage areas, using conventional fractions. Systemic cytostatic therapy was also given to 61% of the patients. RESULTS Staging was as follows: 33% (28/87) I and II, 20% (18/87) IIIA and 47% (41/87) IIIB. The mean radiotherapy dose was 66.7 Gy (95% CI, 65-67). Full clinical remission was achieved by 22% (18/87), half of whom later suffered recurrences. Partial remission was achieved by 26% (21/87). No response was observed in 52% (42/87). Statistically significant differences in actuarial survival rates were found for staging and tumor response. Mean survival for stages I and II was 29 months (95% CI, 19-39), for IIIA it was 22 (95% CI, 16-28) months, and for IIIB 16 months (95% CI, 12-20). The most common complications were cutaneous, esophageal and pulmonary, with a low incidence of grade 3 toxicity (less than 3%) and absence of grade 4. CONCLUSIONS No differences in survival were observed for age, tumor location or histological type. Local control of the disease decisively influenced patient survival.

Abstract
Stage IIIA non-small cell lung cancer represents a relatively heterogeneous group of patients with metastatic disease to the ipsilateral mediastinal (N2) lymph nodes and also includes T3N1 patients. Presentations of disease range from apparently resectable tumors with occult microscopic nodal metastases to unresectable, bulky multistation nodal disease. Controversy abounds as to the optimal treatment of the various stage IIIA subsets, which is fueled by a lack of meaningful, large randomized trials. Multimodality therapy of some type appears to be preferable in stage IIIA patients.

Abstract
Stage IIIB includes patients with T4, any N, M0, and any T, N3, M0. Surgery may be indicated only for carefully selected T4N0M0 patients with or without neoadjuvant chemotherapy or chemoradiotherapy. Patients with N3 lymph node involvement are not considered as surgical candidates. For patients with unresectable disease, good performance score, and minimal weight loss, treatment with combined chemotherapy and radiotherapy has resulted in better survival than treatment with radiotherapy alone. Multiple daily fractions of radiotherapy have not resulted in improved survival compared with standard fractionation once daily. Concurrent chemoradiotherapy appears to be associated with improved survival compared with sequential chemotherapy and radiotherapy. Treatment of stage IIIB due to malignant pleural effusion is addressed in the section that deals with stage IV disease.

Abstract
Chemoradiation is standard treatment for patients with unresectable locally advanced non-small cell lung cancer (NSCLC). However, local and distant relapse rates remain high. It has been postulated that the addition of consolidation chemotherapy might further decrease the systemic relapse rate. We performed this phase II study to evaluate the toxicities and activity of two cycles of paclitaxel and carboplatin administered prior to and following thoracic radiation in patients with locally advanced, inoperable NSCLC. From April to December 1997, 25 patients were entered on study. Twenty-three patients were eligible and received paclitaxel 225 mg/m(2) intravenously over 3 h followed by carboplatin at an AUC (6) on days 1 and 22. Radiation consisted of 60 Gy given over 6 weeks beginning on day 43. Patients with non-progressive disease received two additional cycles of consolidation carboplatin and paclitaxel. Four of 23 patients progressed during induction chemotherapy. There were seven PR's and 11 had SD after induction chemotherapy. Following radiation, the response changed to 11 PR, four SD, and three had progressive disease. Of the 15 patients eligible to receive consolidation chemotherapy, three were excluded due to a poor performance status. Twelve patients were treated with consolidation chemotherapy with further improvement in two patients (SD to PR, PR to CR). All 12 patients who received consolidation chemotherapy developed grade 3 or 4 neutropenia, including three patients with neutropenic fever. The overall response rate was 52.1%. The median survival, 1-, and 2-year survival was 10.5 months, 45, and 17%, respectively. In conclusion, consolidation chemotherapy was associated with significant hematologic toxicity without an obvious improvement in survival in comparison to other studies utilizing chemoradiation alone.

Abstract
The purpose of this trial was to evaluate the feasibility of concurrent paclitaxel/cisplatin and conventional thoracic irradiation in locally advanced non-small cell lung cancer (NSCLC). Ambulatory patients with medically inoperable or unresectable stage II-III NSCLC, and performance status 0-2 were eligible. Patients were not excluded from this trial if they had lost more than 5% of their body weight during the preceding 3 months, and/or if they had small ipsilateral pleural effusion. The initial dose of paclitaxel/cisplatin was 110 and 50 mg/m(2), and was escalated through five dose levels. Four cycles of chemotherapy were planned; the first two cycles were given concurrently with radiotherapy (4 weeks apart), followed by two additional cycles (every 3 weeks). Conventional chest radiotherapy to a total dose of 60 Gy (2 Gy per day) was delivered in 6 weeks. Forty-three patients were enrolled of which 38 were evaluable for response. Dose-limiting toxicities were grade 4 neutropenia (43% of patients) and grade 3 esophagitis (26% of patients) during the chemoradiotherapy phase. Grade > or = 2 acute and late pulmonary toxicity occurred in 10 and 68% of the patients, respectively. In most patients, prompt symptomatic and radiologic improvement was observed with early steroid administration. The volume of lung receiving 15-30 Gy was correlated with late pulmonary toxicity. The overall response was 84% with ten complete and 22 partial responses. The median survival was 16.5 months (95% confidence interval, 9.5 to 25) for those patients evaluable for response. After a median follow-up of 70 months, 5 (13%) patients are alive without evidence of disease. The maximum tolerated dose (MTD) of paclitaxel and cisplatin with concurrent radiotherapy is at dose level 3 paclitaxel (135 mg/m(2)) and cisplatin (75 mg/m(2)). Toxicity, although significant, was manageable in the great majority of the patients. The activity observed with this regimen is particularly noteworthy when considering the advanced nature of these patients, and the fact that patients (N=18) with poor risk factors were included in the study.

Abstract
A phase III randomized trial was conducted to investigate whether induction chemotherapy followed by radiation can influence survival as compared with radiation alone in unresectable, locally advanced non-small-cell lung cancer (LADNSCLC). A total of 101 patients with unresectable stage IIIA or IIIB NSCLC were enrolled. Patients were stratified by performance status, weight loss, histology and stage, and then randomized to receive combined chemoradiotherapy or radiotherapy alone. Radiotherapy was administered in 1.8 Gy to 2.0 Gy standard fractions daily 5 times weekly for a total dose of 60 Gy to 65 Gy. The combined group received induction of cisplatin, etoposide, and vinblastine (PEV) chemotherapy with cisplatin 20 mg/m2 on days 1 to 5, etoposide 100 mg/m2 on days 2 to 4, and vinblastine 6 mg/m2 on day 1, which wasrepeated every 3 weeks for 3 courses, after which time the patients underwent radiotherapy. Of 101 patients registered, 89 patients (43 combined, 46 radiotherapy alone) were eligible for analysis. The response rates for the combined and radiotherapy groups were 65% (28/43) and 70% (32/46), respectively. The median survival time (MST) showed a tendency to be more prolonged in the combined group than in the group receiving radiotherapy alone (13.8 vs. 8.5 months). The MST in patients with nonsquamous histology was strikingly prolonged in the combined group as compared with the radiotherapy group (14 vs. 3.6 months, p 0.027). Likewise, the MST in patients with stage IIIB was significantly prolonged in the combined group as compared with the radiotherapy group (11.1 vs. 7.2 months, p 0.045). Together, the MST of the high-risk group with nonsquamous or stage IIIB was significantly higher in the combined group than that seen in the radiotherapy group (11.6 vs. 8 months, p 0.046), whereas the MST of the low-risk group, defined as having both squamous histology and stage IIIA, was similar in the two treatment groups (18.3 vs. 20.8 months, p = 0.293). In conclusion, induction PEV chemotherapy plus radiotherapy is superior to radiotherapy alone in high-risk subsets of unresectable LAD-NSCLC and therapeutic strategy should be based on the identification of prognostic factors.

Abstract
The split-course concurrent thoracic radiation therapy (TRT) and full-dose chemotherapy for unresectable stage III non-small cell lung cancer (NSCLC) has produced promising results by comparison with the sequential approach. Instead of split-course radiation, we conducted a phase II study to investigate the feasibility of continuous concurrent TRT and chemotherapy. Twenty-two patients with unresectable NSCLC were enrolled onto a phase II study of continuous concurrent radiotherapy and chemotherapy. Treatment consisted of two courses of cisplatin (80 mg/m(2) on days 1 and 29), vindesine (3 mg/m(2) on days 1, 8, 29 and 36), and mitomycin (8 mg/m(2) on days 1 and 29). TRT began on day 2 at a dose of 60 Gy (2 Gy per fraction and 5 fractions per week for a total of 30 fractions). Of 22 patients assessable for response, none achieved a CR and 17 (77.3%) achieved a PR with an overall response rate of 77.3% (95% confidence interval, 54.6-92.2%). Grade 3 or 4 leukopenia was observed in 5/13 (81.8%) patients. Six patients (27.3%) experienced > or = grade 3 thrombocytopenia. Non-hematological toxicity was relatively mild. The overall median survival time was 19.0 months and the 1- and 2-year survival rates were 84.8 and 34.5%, respectively. It was possible to administer two courses of chemotherapy in 18 patients (81.8%) as planned. Nineteen (86.4%) of the 22 patients received the planned 60 Gy radiation. It seems to be difficult to administer the planned treatment without any interruption for the majority of patients. However, in the selected patients who completed the 60 Gy TRT, nearly half of the patients completed TRT without interruption. This combination regimen is considered to be feasible on condition that the stopping rule of the treatment is followed. We recommend administering radiotherapy continuously as far as possible.

Abstract
The treatment options for unresectable stage III NSCLC include definitive RT, chemotherapy, combined chemoradiotherapy, or supportive care. Compared with radiation alone or chemotherapy alone, the combination of chemotherapy and standard RT confers a modest survival benefit at the cost of increased toxicity for patients with an excellent performance status. For metastatic disease, combination chemotherapy--in particular, platinum-based regimens--improves symptom control and survival. Newer chemotherapeutic agents with higher response rates and favorable toxicity profiles are improving outcome even for the elderly and debilitated patients and those refractory to first-line chemotherapy. Evolving understanding of the molecular events in tumorigenesis is uncovering a host of promising targets for mechanism-based therapy. Many of these novel target modulators likely will require combination with conventional chemotherapy for optimal results.

Abstract
BACKGROUND Overall prognosis of patients with locally advanced non-small-cell lung cancer (LAD-NSCLC) is still unfavourable. Different attempts to improve treatment results have been made using combinations of chemotherapy and radiotherapy. The aim of this pilot phase I/II investigation was to test the feasibility and toxicity of a definitive multimodality protocol in patients with irresectable NSCLC stages IIIA (N2) and IIIB. PATIENTS AND METHODS Thirty LAD-NSCLC patients (stages IIIA/IIIB: 3/27; median age: 54 years, range 34-70; male/female: 17/13) who were consecutively enrolled onto our ongoing neoadjuvant multimodality protocol from October 1996 to February 1999 remained inoperable after induction treatment. Three cycles of cisplatin/etoposide (PE) were followed by hyperfractionated accelerated radiotherapy (HF-RTx: 1.5 Gy bid up to a total dose of 45 Gy in 3 weeks) concurrent with one cycle of PE. Definitive local treatment was completed with a small volume boost of 20 Gy (qd), adding up to a total dose of 65 Gy to the primary. Patients were routinely offered prophylactic cranial irradiation (PCI; 30 Gy; 2 Gy qd). RESULTS Overall toxicity of the definitive CTx/RTx protocol-the main endpoint of this investigation-turned out to be acceptable (oesophagitis grade 3/4: 6/4 patients; pneumonitis grade 3/4: 0/1 patients; no treatment-related deaths). Actuarial survival at 2 years was 31% with a loco-regional control rate of 21%. CONCLUSIONS This regimen turned out to be feasible with acceptable toxicity and will serve as a reference arm in a planned randomised trial in stage IIIB NSCLC, testing the value of surgery in this setting: preoperative induction CTx/RTx followed by surgery versus definitive CTx/RTx.

Abstract
BACKGROUND Therapy for prostate cancer in the PC3 tumor-nude mouse model with 90yttrium-(90Y)-DOTA-peptide-ChL6 (5.55 MBq;150 microCi) has resulted in durable responses. To make radioimmunotherapy (RIT) more effective, the radiation-enhancing drugs Taxol (paclitaxel) and Taxotere (docetaxel) were tested for synergy with 90Y-DOTA-peptide-ChL6. METHODS Nude mice bearing human prostate cancer PC3 xenografts were treated with 90Y-DOTA-peptide-ChL6 (2.78 MBq; 75 microCi) and after 24 hr, paclitaxel (300 or 600 microg), or docetaxel (300 microg). Tumor size, survival, blood counts, and pharmacokinetics were monitored to assess efficacy and toxicity. RESULTS Docetaxel plus RIT had a 67% cure rate, whereas no mice were cured among the RIT alone, chemotherapy alone, or untreated controls. Paclitaxel (600 microg) plus RIT produced a 100% response rate with 20% cures. Average tumor volume was reduced to a greater degree in the combined modality radioimmunotherapy (CMRIT) groups compared to controls and the anti-tumor response was durable. Myelotoxicity in the combined modality groups (RIT plus paclitaxel or RIT plus docetaxel) were similar to groups receiving the same dose of RIT alone. CONCLUSION In the PC3-tumor nude mouse model, addition of paclitaxel or docetaxel to 90Y-DOTA-peptide-ChL6, in doses clinically achievable in humans, provided therapeutic synergy without increased or excessive toxicity.

Abstract
The ultimate goal of any strategy in oncology is to enhance the therapeutic ratio, defined as tumor cell kill divided by normal tissue injury. Whereas most trials focus on intensifying therapy, this often increases toxicity so that there is no overall gain in the therapeutic ratio. Radiation Therapy Oncology Group (RTOG) trial 98-01, a phase III study testing the ability of a radioprotector (Amifostine [Ethyol, WR-2721]) to reduce the toxicity of an intensive chemoradiation regimen for locally advanced non-small cell lung cancer (NSCLC), is unique in that it addresses both "sides" of this equation. During the 1990s, thoracic radiotherapy (RT) combined with chemotherapy was accepted as a "new" gold standard for patients with good performance status locally advanced/inoperable NSCLC. This paradigm shift away from RT alone has raised several key questions: What is the optimal method of integrating chemotherapy and RT? Equally importantly, how can the toxicity of combined modality strategies be reduced? This article will review the background underlying RTOG 98-01, a trial exploring the potential role of amifostine in NSCLC.

Abstract
Lung cancer is the leading cause of cancer mortality in the United States for both men and women. Twenty to thirty percent of patients with non-small cell lung cancer (NSCLC) present with locally advanced, unresectable tumors. While small improvements in outcome have occurred for this group of patients in the last decade, 5-year survival remains low, ranging from 5 to 20%. Distant metastases and loco-regional progression remain significant patterns of failure. Up to the late 1980s, the standard management was conventional thoracic radiotherapy for locally advanced NSCLC, but when treated with radiotherapy alone, less than 10% of patients survived for 5 years or more. Sixty to seventy percent failed at distant sites and less than 20% achieved durable local control. The addition of chemotherapy reduces the rate of distant failure, improves survival and the combination of chemotherapy and radiotherapy has become the standard of care of patients with locally advanced NSCLC. Current developments aim to optimise individual components of combined modality schedules, increase their synergism and minimise toxicity.

Abstract
The utilization of systemic chemotherapy within multi-modality treatment concepts in early stage NSCLC would seem to be a very promising concept, which potentially could lead to increased survival rates. It must be noted, however, that application of multi-modality treatment strategies in Stage I and II NSCLC is still experimental and should only be applied within clinical trials. Caution is thus advisable because the existing data are not conclusive and there still are a great number of questions to be answered concerning at least: (1) the regimen, the intensity, the duration of therapy and the most appropriate schedule to be used for chemotherapy, (2) the most appropriate time for surgery and its extensiveness, and (3) the time, dose, and best application modus for radiotherapy. The Lung Cancer Group of the EORTC has been active in the clinical development of multi-modality treatment strategies to improve treatment results for patients with localized, early NSCLC and presently offers its members several attractive studies dealing with induction preoperative chemotherapy, induction preoperative chemo-radiotherapy, and sequential/concomitant chemo-radiotherapy.

Abstract
INTRODUCTION This phase II study was designed to assess the activity and tolerability of the carboplatin-paclitaxel combination, given without routine growth factor support to previously untreated patients with stage IIIB and IV non-small cell lung cancer. PATIENTS AND METHODS Sixty patients (15 stage IIIb and 45 stage IV) received paclitaxel 225 mg/ml on day 1, followed by carboplatin AUC 6 mg/ml per minute (Calvert formula) every 3 weeks. Paclitaxel was administered as a 3-h intravenous infusion followed by carboplatin over 30 min, on completion of paclitaxel administration. RESULTS The combination showed a good safety profile with Grade 4 neutropenia occurring in 31% of patients without any serious infectious episodes requiring hospitalization. Moderate to severe anemia and thrombocytopenia seldom occurred. Sensorimotor peripheral neuropathy (Grade 2-3) and myalgia (Grade 3-4) were documented in 34 and 20% of the patients, respectively. Among 59 evaluable patients, there was one complete response and 26 partial responses for an overall response rate of 46% (95% C.I.: 34-59%). With a minimum follow-up duration of 16.5 months, the median overall survival time is 52 weeks and the 1-year survival rate is 50%. Median duration of response is 20 weeks (range: 4-52) and progression-free survival is 22 weeks (range: 5-77). CONCLUSION In advanced NSCLC, the combination carboplatin-paclitaxel at doses of AUC 6 mg/ml per minute and 225 mg/ml every 3 weeks, is both active and relatively well-tolerated.

Abstract
The paclitaxel/carboplatin combination has demonstrated promising activity in metastatic non-small-cell lung cancer (NSCLC); therefore, we mounted an exploratory study of these agents with thoracic radiation (TRT) in locally advanced NSCLC. Eligibility stipulated a Karnofsky performance status >or= 70%, weight loss <or= 5%, and primarily stage IIIB or bulky IIIA NSCLC. Induction chemotherapy (CT), 2 cycles of paclitaxel 175-225 mg/m2 over 3 hours and carboplatin (targeted area under the curve [AUC] of 7.5), was administered on days 1 and 22. Granulocyte colony-stimulating factor (G-CSF) 5 microg/kg was given on days 2-15 and 23-36 to all patients; half were randomized to priming G-CSF every day x 5 prior to day 1 of induction therapy. On day 43, TRT (60-63 Gy/30-34 fx) was initiated. At dose level 1, only Fox Chase Cancer Center patients received carboplatin (initial target AUC 3.75) and paclitaxel (67.5 mg/m2 over 3 hours) days 43 and 64. In the absence of dose-limiting toxicity, phase I dose escalation in 3-patient cohorts was scheduled to proceed to a maximum carboplatin AUC 7.5 and paclitaxel dose of 210 mg/m2. To date, 53 patients have received induction therapy; 4 are too early to evaluate. The portion of the study evaluating G-CSF priming revealed no myeloprotective effect, likely due to a lack of myelosuppressive toxicity with the conventionally dosed cohort. Twenty-two patients have received concurrent TRT/CT. In sequential cohorts, the chemotherapy doses on days 43 and 64 have been escalated (to paclitaxel 175 mg/m2 and carboplatin AUC 5) with 1 episode each of grade 4 granulocytopenia and grade 3 anemia. The occurrence of grade >or= 2 esophagitis has corresponded to length (> 16 cm) of esophagus in the radiation treatment field (Fisher's exact test, P = 0.006). The partial response rate to induction therapy was 40% and to the combined modality therapy was 60%. The median survival for all 49 patients is 15.3 months, with a median disease-free survival (DFS) of 7.8 months. In the subset of 22 patients treated on the phase I portion of the study, the median survival and DFS were 18.5 months and 13.5 months, respectively. Induction therapy with paclitaxel and carboplatin followed by concurrent chemoradiotherapy with the same agents is an active and well-tolerated treatment approach in locally advanced NSCLC. To date, paclitaxel 175 mg/m2 plus carboplatin AUC 5 administered at 3-week intervals for 2 cycles is safe in combination with TRT.

Abstract
PURPOSE The ability to prescribe treatment based on relative risks for normal tissue injury has important implications for oncologists. In non-small-cell lung cancer, increasing the dose of radiation may improve local control and survival. Changes in plasma transforming growth factor beta (TGFbeta) levels during radiotherapy (RT) may identify patients at low risk for complications in whom higher doses of radiation could be safely delivered. PATIENT AND METHODS Patients with locally advanced or medically inoperable non-small-cell lung cancer received three-dimensional conformal RT to the primary tumor and radiographically involved nodes to a dose of 73.6 Gy (1.6 Gy twice daily). If the plasma TGFbeta level was normal after 73.6 Gy, additional twice daily RT was delivered to successively higher total doses. The maximum-tolerated dose was defined as the highest radiation dose at which < or = one grade 4 (life-threatening) late toxicity and < or = two grade 3 to 4 (severe life-threatening) late toxicities occurred. RESULTS Thirty-eight patients were enrolled. Median follow-up was 16 months. Twenty-four patients were not eligible for radiation dose escalation beyond 73.6 Gy because of persistently abnormal TGFbeta levels. Fourteen patients whose TGFbeta levels were normal after 73.6 Gy were escalated to 80 Gy (n = 8) and 86.4 Gy (n = 6). In the 86.4-Gy group, dose-limiting toxicity was reached because there were two (33%) grade 3 late toxicities. CONCLUSION It is feasible to use plasma TGFbeta levels to select patients for RT dose escalation for non-small-cell lung cancer. The maximum-tolerated dose using this approach is 86.4 Gy.
