- PURPOSE: The impact of stereotactic body radiotherapy (SBRT) on 3-year progression-free survival of medically inoperable patients with stage I non-small-cell lung cancer (NSCLC) was analyzed in a prospective phase II study. PATIENTS AND METHODS: Fifty-seven patients with T1NOMO (70%) and T2N0M0 (30%) were included between August 2003 and September 2005 at seven different centers in Sweden, Norway, and Denmark and observed up to 36 months. SBRT was delivered with 15 Gy times three at the 67% isodose of the planning target volume. RESULTS: Progression-free survival at 3 years was 52%. Overall- and cancer-specific survival at 1, 2, and 3 years was 86%, 65%, 60%, and 93%, 88%, 88%, respectively. There was no statistically significant difference in survival between patients with T1 or T2 tumors. At a median follow-up of 35 months (range, 4 to 47 months), 27 patients (47%) were deceased, seven as a result of lung cancer and 20 as a result of concurrent disease. Kaplan-Meier estimated local control at 3 years was 92%. Local relapse was observed in four patients (7%). Regional relapse was observed in three patients (5%). Nine patients (16%) developed distant metastases. The estimated risk of all failure (local, regional, or distant metastases) was increased in patients with T2 (41%) compared with those with T1 (18%) tumors (P = .027). CONCLUSION: With a 3-year local tumor control rate higher than 90% with limited toxicity, SBRT emerges as state-of-the-art treatment for medically inoperable stage I NSCLC and may even challenge surgery in operable instances.

- BACKGROUND AND AIMS: In a retrospective study using stereotactic body radiotherapy (SBRT) in medically inoperable patients with stage I NSCLC we previously reported a local control rate of 88% utilizing a median dose of 15Gyx3. This report records the toxicity encountered in a prospective phase II trial, and its relation to coexisting chronic obstructive pulmonary disease (COPD) and cardio vascular disease (CVD). MATERIAL AND METHODS: Sixty patients were entered in the study between August 2003 and September 2005. Fifty-seven patients (T1 65%, T2 35%) with a median age of 75 years (59-87 years) were evaluable. The baseline mean FEV1% was 64% and median Karnofsky index was 80. A total dose of 45Gy was delivered in three fractions at the 67% isodose of the PTV. Clinical, pulmonary and radiological evaluations were made at 6 weeks, 3, 6, 9, 12, 18, and 36 months post-SBRT. Toxicity was graded according to CTC v2.0 and performance status was graded according to the Karnofsky scale. RESULTS: At a median follow-up of 23 months, 2 patients had relapsed locally. No grade 4 or 5 toxicity was reported. Grade 3 toxicity was seen in 12 patients (21%). There was no significant decline of FEV1% during follow-up. Low grade pneumonitis developed to the same extent in the CVD 3/17 (18%) and COPD 7/40 (18%) groups. The incidence of fibrosis was 9/17 (53%) and pleural effusions was 8/17 (47%) in the CVD group compared with 13/40 (33%) and 5/40 (13%) in the COPD group. CONCLUSION: SBRT for stage I NSCLC patients who are medically inoperable because of COPD and CVD results in a favourable local control rate with a low incidence of grade 3 and no grade 4 or 5 toxicity.

Journal article (peer-reviewed)abstract
- PURPOSE: A Japanese randomized trial showed superior survival for patients with extensive-disease (ED) small-cell lung cancer (SCLC) receiving irinotecan plus cisplatin compared with etoposide plus cisplatin. The present trial evaluated the efficacy of irinotecan plus carboplatin (IC) compared with oral etoposide plus carboplatin (EC). PATIENTS AND METHODS: Patients with ED SCLC were randomly assigned to receive either IC, which consisted of carboplatin (area under the curve = 4; Chatelut formula) and irinotecan (175 mg/m2) intravenously both on day 1, or EC, which consisted of carboplatin as in IC and etoposide (120 mg/m(2)/d) orally on days 1 through 5. Courses were repeated every 3 weeks with four cycles planned. Doses were reduced by one third in patients with a WHO performance status (PS) of 3 to 4 and/or age older than 70 years. Primary end point was overall survival (OS). Secondary end points were quality of life (QOL) and complete response (CR) rate. RESULTS: Of 220 randomly assigned patients, 209 were eligible for analysis (IC, n = 105; EC, n = 104). Thirty-five percent were older than 70 years, and 47% had a PS of 2 to 4. The groups were well balanced with respect to prognostic factors. OS was inferior in the EC group (hazard ratio = 1.41; 95% CI, 1.06 to 1.87; P = .02). Median survival time was 8.5 months for IC compared with 7.1 months for EC. One-year survival rate was 34% for IC and 24% for EC. CR was seen in 18 IC patients compared with seven EC patients (P = .02). There were no statistically significant differences in hematologic grade 3 or 4 toxicity. Grade 3 or 4 diarrhea was more common in the IC group. QOL differences were small, with a trend toward prolonged palliation with the IC regimen. CONCLUSION: IC prolongs survival in ED SCLC with slightly better scores for QOL.

Journal article (peer-reviewed)abstract
- BACKGROUND: A combination of chemotherapy and radiotherapy is the treatment base for locally advanced non-small cell lung cancer (NSCLC). However, both loco-regional and distant failure is frequent. Attempts to improve the loco-regional control were made in three separate phase II studies in Swedish University Hospitals, where accelerated radiotherapy or concurrent daily or weekly chemotherapy with conventional radiotherapy were tested. Comparatively good results from these studies lead to this national randomized phase II study, the RAKET-study, where the different concepts were investigated on a wider basis for further phase III studies. METHODS: Inoperable stage III non-small cell lung cancer patients in good performance status (PS<2) were equally randomized to either of three arms in eight institutions. All arms started with two cycles of induction chemotherapy: paclitaxel 200 mg/m2 and carboplatin AUC6. Arm A: a third identical cycle was given concomitant with start of accelerated radiotherapy, 1.7 Gy BID to 64.6 Gy in 4.5 weeks. Arm B consisted of daily concomitant paclitaxel 12 mg/m2 with conventionally fractionated radiotherapy: 2 Gy to 60 Gy in 6 weeks. Arm C: weekly concomitant paclitaxel 60 mg/m2 and identical radiotherapy to 60 Gy. Primary endpoint: TTP. Secondary: OS, toxicity, QL and relapse pattern. RESULTS: Between June 2002 and May 2005 152 patients were randomized and of them 151 were evaluable: 78 men and 73 women, median age 62 years (43-78), 55% had performance status 0 and 45% PS 1. Thirty-four percent had stage IIIa and 66% IIIb. Histology: adenocarcinoma 48%, squamous cell carcinoma 32% and 20% non-small cell carcinoma. The three arms were well balanced. Toxicity was manageable with 12% grades 3-4 esophagitis, 1% grades 3-4 pneumonitis and there was no clear difference between the arms. The QL data did not differ either. Median time to progression was 9.8 (8.3-12.7) months (8.8, 10.3 and 9.3 months for arms A, B and C, respectively). Median survival was 17.8 (14.4-23.7) months (17.7, 17.7 and 20.6 months for A, B and C, respectively). The 1-, 3- and 5-year overall survival was 63, 31 and 24%. Sixty-nine percent of the patients relapsed with distant metastases initially and 31% had loco-regional tumor progression, without significant differences between treatment arms. Thirty-four percent developed brain metastases. CONCLUSIONS: Treatment results are quite equal by intensifying the loco-regional treatment either by accelerated fractionated radiotherapy or daily or weekly concomitant chemo-radiotherapy both in terms of survival, toxicity and quality of life. The optimal treatment schedule for patients with locally advanced NSCLC is still to be decided and investigated in future clinical studies. Relapse pattern with distant metastases and especially brain metastases is a great problem and need further research for better therapy options and higher cure rate for this patient group.

- Aim: To evaluate weekly, induction chemotherapy followed by weekly concomitant chemoradiotherapy in a multicentre phase II study of patients with wiresectable stage III non-small cell lung cancer (NSCLC; stage wet IIIB excluded). Patients (aid Methods: Eligible patients received three weekly cycles of paclitaxel 100 mg/m(2) and carboplatin AUC2 followed by six weekly cycles of paclitaxel 60 mg/m(2) and carboplatin AUC2 in combination with thoracic radiotherapy (2 Gy per fraction and day to a total (lose of 60 Gy), Results: Sixty-four patients (40 males and 24 females) with a median age of 63 Years (range, 43-79 years) entered the study. T and N stage were distributed as follows: T1 2 patients (3.2%). T2 10 patients (15.6%), T3 15 patients (23.4%). T4 37 patients (57.8%), N0 10 patients (15.6%). N1 1 patient (1.6%), N2 26 patients (40.6%), N3 26 patients (40.6%), and N missing I patient (1.6%). Seven patients (10.9%) suffered from grade 314 oesophagitis. Grade 112 oesophagitis occurred in 36 patients (56.3%) and pneumonitis grade 112 occurred in 10 patients (15.6%). Sixty-three patients were evaluated on an intent-to-treat basis. The overall response rate was 74.6%. The median time to progression was 247 days and median overall survival was 461 days. According to subgroup analyses, no statistically signicant differences were noted according to gender, age (<65 vs. >= 65 years), perfromance status, histology, or study centre. Conclusion: Induction chemotherapy followed by concurrent chemoradiotherapy with weekly cycles of paclitaxel and carboplatin is feasible and generates moderate toxicity. Efficacy is comparable to other recently published regimens. However, prognosis remains, ill general, poor for this group of patients and further work to develop better therapy is required.
