CRITERIOS EXCLUSION

• Previous chemotherapy for advanced NSCLC.
• History of haemoptysis grade ≥ 2 (defined as at least 2.5 mL of bright red blood) in the 3 months before inclusion.

• Untreated brain metastases. Patients with CNS metastases treated with radiotherapy or surgery may be included if there is no evidence of progression after treatment
• Radiological evidence of a tumor that invades or is adjacent to a main blood vessel (e.g. lung artery or superior cava venous).
• Radiotherapy, in any lesion and for any reason, within 28 days before inclusion. Palliative radiotherapy for bone lesions within 14 days before inclusion is allowed.
• Treatment with aspirin (>325 mg/day) or clopidogrel (>75 mg/day) within 10 days prior to bevacizumab first dose. Use of full dose of oral or parenteral anticoagulants or thrombolytic agents in therapeutic doses. Prophylactic use of anticoagulant therapy is allowed.
• Uncontrolled hypertension (systolic BP >140 mmHg, diastolic BP >90mmHg) in the 28 days previous to inclusion or history of hypertensive crisis, or hypertensive encephalopathy.

• Not healed wounds, active peptic ulcer or untreated bone fracture.
• Hypersensibility to any of the active ingredients of the study treatment (bevacizumab, carboplatine and paclitaxel) or any of its excipients.
• Serious cognitive impairment that limits the patient to understand and answer the study questionnaires.
• Inability to comply with the study protocol and/or follow-up procedures due to psychological, familiar, social or geographical problems
• Patients with an ADL score <5 at the screening.
• Patients with dementia: 9-12 points in the Folstein MMS at the screening.

• Patients accomplishing fragility Balducci criteria at the screening:

  • Age ≥ 85 years old
  • Dependence in 1 or more ADL
  • >3 comorbilities
  • >1 geriatric syndrome

OBJETIVOS

To assess the toxicity of the treatment in elderly patients (≥70 years) with NSC lung cancer who meet inclusion criteria for bevacizumab and selected based on a geriatric evaluation.

Determine predictive factors of toxicity in the elderly population (≥70 years). Determine objective response rate Determine disease control rate Determine progression free survival Determine overall survival Determine safety of the treatment combination

VARIABLES

Primary endpoint:

Rate of grade 3-4 neutropenia defined according to National Cancer Institute Common Terminology Criteria version 4.0 (NCI-CTC v4.0).

Secondary endpoints:

• Items of the Comprehensive Geriatric Assessment (CGA) scale as predictive factors for toxicity end-points.
• Objective response according to the Response Evaluation Criteria In Solid Tumors (RECIST v1.1).
• Progression-free survival.
• Overall survival.
