      09:30 - 16:30  |  Author(s): F. Cardenal

      • Abstract

      Background
      INTRODUCTION: Oligometastasic pathology has become a usual pathology present in our clinical routine activity.Although invasive treatments are available, SBRT is a non invasive therapy which can be a viable treatment of choice.We introduce our preliminary study of pulmonary lesions treated using a single fraction of 34Gy OBJECTIVES: The main goal of this report is to demonstrate that a fraction of 34Gy is a viable and attainable therapy to treat lesions in oligometastasic patient’s lungs

      Methods
      Seven patients with 7 pulmonary lesions were treated with single dose of 34Gy. Inclusion criteria were : lesion size smaller than 2 cm , distance from the chest wall and main bronchus tree higher than 2 cm , primary tumor under control in PET scan. Mean Age 61.57y (r39-82), Gender distribution 3 women and 4 men, Histology: 4 cases (57.14% were Metastasic lesions from Colon), 1 metastasic from Adenoid Cystic, 1 Adenocarcinoma from Lung and 1 NSCLC. All patients underwent 4DCT for contouring. Inmobilization was done by thermoplastic mask (Lorca Marin) . Dosimetric characteristics: Mean volume of GTV 1.46cc (r 0.6-4.1), mean volume of PTV 11.29cc (r7.1-22.2), D Max oesophagus 5.06 (r 2.6-8.4), D max Heart 4.05 (r6.86-17.0), D max trachea 5.12 Gy (r 0.3-11.1), Dmax skin 10.98(r7.0-14.4). Patients were treated using True Beam machine. In 6 cases treatments were delivered without flattering filter beams

      Results
      After 6 months of follow up (r 6-2.19) no toxicity higher than grade 2 was detected. Local control rates and survival are 100%, 100% respectively. To sum up, even this is a preliminary study, seems than long term results can show us a new perspective in these oligometastasic patients.

      Conclusion
      not applicable

      P2.08-010 - Outcome of Epidermal Growth Factor Receptor mutated (EGFRm) non-small cell lung cancer (NSCLC) patients (p) with Brain metastases (BM) in a single institution: Value of the lung-GPA classification (ID 1309)

      09:30 - 16:30  |  Author(s): F. Cardenal

      • Abstract

      Background
      In February 2012 a specific GPA scale for assessing the prognosis of BM in NSCLC was published (JCO, 2012; 30(4): 419-426). Retrospective series have showed longer survival for patients with cerebral metastases and EGFR sensitizing mutations (m) compared with those without them.

      Methods
      Charts from EGFRm NSCLC p with BM were reviewed. We classified p with the lung-GPA prognosis scale at the time of diagnosis of BM and compared the expected GPA overall survival (GPA-OS) with the Observed OS (OS) for each group.

      Results
      24p were diagnosed from January 2007 to December 2012. 15 p were treated with whole-brain radiotherapy (WBRT), total dose 30Gy (2p GPA 0-1; 10p GPA 1.5-2; 3p GPA 2.5-3), 1 p with stereotactic radiosurgery (SRS), mean dose 18Gy (GPA 3.5-4), 1p with SRS and WBRT (GPA 2.5-3) and 2p with surgery (S) and WBRT (1p GPA 2.5-3; 1p GPA 3.5-4). 5p receive no treatment (3p GPA 0-1; 2p GPA 1.5-2). Outcomes were [Expected median (m) GPA-OS vs Observed m OS]:

      GPA Expected m GPA-OS(months) Observed m OS (months) Number of p
      0-1 3.4 <1 5
      1.5-2 4.7 6 12
      2.5-3 8.8 34 5
      3.5-4 14.8 Not reached (100% OS at 40 months) 2
      Two p did not receive any EGFR tyrosine kinase inhibitor (TKI). 5p were receiving an EGFR TKI when they were diagnosed with BM and 12p were treated with EGFR TKI after the diagnosis of BM. Sixteen p have died. Further details of p characteristics and treatment received will be presented at the meeting.

      Conclusion
      Observed m OS of p with EGFR m-NSCLC and brain mets was much longer than expected by GPA-OS. The GPA subsets might predict prognosis in patients with mutated tumors as well.

      P2.09-004 - Phase II study of sequential versus concurrent chemotherapy and radiotherapy in poor risk patients with inoperable stage III non-small cell lung cancer (NSCLC): final results of the Spanish Lung Cancer Group 00-05 study (ID 1102)

      09:30 - 16:30  |  Author(s): F. Cardenal

      • Abstract

      Background
      Inoperable stage III NSCLC is increasingly diagnosed in poor-risk patients for whom there is not yet a standard treatment. We conducted a randomized two-stage phase II study to assess whether sequential or concurrent chemoradiation was feasible, tolerable and showed efficacy.

      Methods
      Patients with inoperable stage IIIA and B NSCLC and at least one of the following conditions: age ≤ 75 years, ECOG PS=2, weight loss > 5%, creatinine clearance < 60 ml/min, a comorbid condition precluding the patient from being treated in a protocol for fit patients,were randomized to receive either carboplatin AUC 2.5 and vinorelbine 15 mg /m[2] both on days 1,8,22, and 29, and thoracic radiotherapy (TRT) total dose 60 Gy starting day 1 (CT arm) or, carboplatin AUC 5, days 1 and 22 and vinorelbine 25 mg/m[2] days 1, 8, 22, and 29, followed by TRT 60 Gy starting day 43 to 50 (ST arm). The primary end-point was response rate.

      Results
      From June 2001 to June 2006, 70 patients from 8 centers were included : 47 in CT arm and 23 in ST arm. Forty-eight of these patients were randomized during the first stage of the trial. By September 2004, due to a decrease in treatment compliance and an increase in early deaths in the ST arm, accrual was continued in the second stage of the trial only in the CT arm. Patient characteristics: median age 74 (49-84), Male 96%, Stage IIIB 65%; ECOG =2, 28%; Weight loss >5%, 29%; Creatinine clearence <60, 26%; Comorbidity, 70%. More than one poor risk inclusion criteria: 59 %. Fifty-eight patients completed treatment 93 % in CT arm, and 73% in ST arm. There were 2 CR and 25 PR (RR 60%) in CT arm, and 10 PR (RR 45.5%) in ST arm. Grade 3- 4 hematological toxicity was absent in CT arm and was 14% (neutropenia) in ST arm. Grade 3 and 4 non-hematological toxicities experienced by more than 5% of patients were asthenia (7%) and dyspnea (9%) in CT arm and anorexia (9%), asthenia(14%), and dyspnea (14%) in ST arm. Only one patient developed grade 3 esophagitis (CT arm) There were five deaths during treatment: two in CT arm and three in ST arm. Median PFS and overall survival rate were 6.7 (95% CI:4.9-8.5) and 16.8 months (95% CI 9.5-24), and 7.9 (95% CI:3.9-16.2) and 5.6 months (95% CI:2.7-8.9 ), for the CT arm and ST arm, respectively.

      Conclusion
      In poor-risk patients with inoperable stage III NSCLC, concurrent chemoradiotherapy outperformed sequential chemotherapy and radiotherapy, and was feasible, very well tolerated, and provided efficacy. The survival outcome with concurrent chemoradiotherapy was notably longer than anticipated.
