Pulmonary lymphangitis and cancer: Prospective series of 37 patients in palliative care

Abstract

18600 Background: Lymphangitis of the lungs is an uncommon type of metastasis, mainly in breast, lung and gastric cancers, and has major impact in quality of life and an unfavorable prognosis. Survival is very poor: 50% in 3 and 15% in 6 months. Our objective was to evaluate prospectively quality of life in cancer patients with pulmonary lymphangitis, under palliative care. Methods: Patients with pulmonary lymphangitis, diagnosed either by lung biopsy (major criteria) or 3 minor criteria (cyto or histotologically proven cancer, clinical picture and image exam) were followed in 3 tertiary services, in a cohort series study. Primary end point was quality of life (QoL), measured with questionnaires in the beginning of the study and monthly afterwards (Saint George Respiratory Questionnaire -SGRQ- and Medical Outcomes Study 36-Item Short-Form Health Survey -SF36). Clinical and complementary aspects were also followed, in addition to treatment and outcome. Results: Thirty-seven patients were included from Aug/2004 to Jan/2006 - 23 female and 14 male; age from 41 to 84 (mean: 62) years. Primary tumors were: lung (20), breast (11), esophagus (2), pancreas, rectum and bone. Of those patients, 33 were able to respond QoL questionnaires in the beginning of follow-up and monthly thereafter. Median follow-up was of one month (range: 0–13); at the moment, 9 patients are still alive. Median survival was 2.5 months (range: 0,1–33), with 38% with a survival of at least 6 months. In general, QoL was poor, but improved after palliative care. Notice that values get higher as QoL improves in SF-36; however, they get lower as QoL improves in SGRQ - values were 61.5, 50.5, 61.7, and 47.5% for SGRQ and 38.1, 32.1, 32.8, 61.6 for SF36 in 0, 1, 3 and 6 months, respectively. Palliative care included: corticosteroids (65%), oxygen (51%), opioids (51%), diuretics (47%), inhalations with beta2-agonists and/or ipatropium (57%), chemo and/or hormonotherapy (51%), physical therapy (43%), antidepressants and benzodiazepines (37% each), thoracocentesis (35%), and blood transfusions. Conclusions: Even though QoL is poor and survival is short for patients with cancer lymphangitis in lungs, some improvement is possible with active palliative care.
