    Background
    

    Special attention is required by elderly population, due to chemotherapy (ch) risks and comorbidities, which may limit the capacity to deliver optimal cancer care. We aimed to describe the clinical features and survival outcomes of elderly patients (pts) with lung adenocarcinoma (ADC) treated with non-curative intent at A. C. Camargo Cancer Center.

    We evaluated all pts aged 70+ with lung ADC treated with ch or target therapy in 1st or 2nd-line from 2007 to 2015 who underwent a comprehensive geriatric assessment (CGA), in a convenient prospective series. We used summary statistics to describe the population. Overall survival (OS) was calculated according to Kaplan-Meier method, from CGA date to last follow-up or death. We performed univariate and multivariate analysis in order to look for potential prognostic factors for OS.

    CGA was done in 55 pts aged ≥70y with lung ADC. The median age was 76y and 22% had ECOG ≥ 2. Half of pts were male. 51% had polypharmacy (≥5 drugs). Pts were functionally classified according to activities of daily living (ADL): 76% as Katz A and 50% as Lawton ≤27. 68.5% were at risk for malnutrition or malnourished. The median age-adjusted Charlson Comorbidity score was 10 – remembering that 4+ is considered clinically significant. 61% had ≥2 comorbidities and 26 pts had at least 2 metastatic sites. CNS was affected in 7.5% of the cases and liver in 9.2%. 79.6% of the pts underwent ch and the others received target therapy. After follow-up of 29m, median OS was 17.1 months (13.5-27.8m). In univariate analysis, significantly worse survival outcomes were observed for pts with ECOG 2-4 (HR 10.6; p < 0.001), increasing number of sites of metastases (HR 2.2; p = 0.04) and hepatic metastasis (HR 6.03; p < 0.001). In the multivariate analysis, male gender, ECOG 2-4 and liver metastasis were associated with higher risk of death.

    ADL, an important part of CGA, showed little prognostic value in our small population. Pts with ECOG 2-4 or hepatic metastasis were those that presented the highest risk of death. CGA is a good tool to help in stratifying risk of elderly cancer pts and is mandatory in cost-benefit analysis to identify the best treatment to each individual patient.
