RESUMO

BACKGROUND: Frail patients with non-Hodgkin's lymphoma (NHL) are generally excluded from clinical trials and not even treated. The aim of this study was to evaluate the efficacy and tolerability of vinorelbine and prednisone in frail elderly patients with NHL. PATIENTS AND METHODS: Thirty consecutive frail elderly patients were entered in a phase II study with vinorelbine 25 mg/m2 i.v. on days 1 and 8 and oral prednisone 30 mg total dose on days 1-8 for six cycles. Criteria of frailty were age > or =80 years, or age > or =70 years and three or more comorbidities of grade 3 or at least one comorbidity of grade 4 according to the Cumulative Illness Rating Scale (CIRS), or not self-sufficient or the presence of one or more geriatric syndromes. RESULTS: Of 30 evaluable patients, three (10.0%) achieved a complete response (CR), nine (30.0%) showed a partial response (PR), while 10 presented with stable disease and eight with progressive disease. The median duration of CR was 29 months (range 5-36 months), and the median duration of PR was 1 month (range 1-22 months). Three patients had grade 3 neutropenia and one had grade 4. One grade 4 neurotoxicity was observed. Three patients died because of heart failure within 28 days of therapy, and one patient died after 4 days because of rapid progression. The median overall survival was only 10 months. CONCLUSION: Vinorelbine and prednisone is a relatively non-toxic combination with modest activity in frail patients with NHL. If initial aggressive chemotherapy has been excluded, this combination could be tried to obtain a temporary palliation.

RESUMO

PURPOSE: Th2 lymphocytes may play a key role in the development of allergic diseases such as vernal keratoconjunctivitis (VKC). Cytokine flow cytometry of tear samples was used to identify the phenotypical and functional properties of lymphocytes at the actual site of the allergic reaction. METHODS: Tear and blood samples were obtained from patients affected by active VKC (n = 12) and from normal control subjects (n = 10). Tears were obtained after gentle scraping of the tarsal and bulbar conjunctiva. Tear and blood samples were placed in a solution of brefeldin-A, phorbol myristate acetate (PMA), ionomycin, and RPMI for 4 hours and then processed for flow cytometry. Lymphocytes were marked with the monoclonal antibodies, anti-IFN-gamma and anti-interleukin (IL)-4. Levels of IL-4, IL-2, IFN-gamma, IL-2R, total IgE, eosinophil cationic protein (ECP), eosinophil protein X/neurotoxin (EPX), and myeloperoxidase (MPO) were also evaluated in serum. RESULTS: Expression of IL-4 was observed in 9.2%+/-9.5% of lymphocytes in tears of patients with VKC. Of the 12 patients with VKC, 8 (67%) had tear lymphocytes positive for IL-4 (Th2). Two patients (17%) had a double population of lymphocytes: One was positive for Th2, and the other was positive for both IL-4 and IFN-gamma (Th0). One patient (8%) was positive for IFN-gamma (Th1) only, and one patient was negative for both ILs. No differences in the percentage of Th2 lymphocytes were found between tarsal and limbal patients. The percentage of Th2 lymphocytes was significantly correlated with the severity of the disease. No positive lymphocytes were found in tears of control subjects. Eosinophils, serum IgE, ECP, and EPX were all significantly higher in VKC than in control subjects. CONCLUSIONS: In ocular allergic diseases, local lymphocytes expressed the Th2 phenotype and, to a lesser degree, the Th0 phenotype. Although results of systemic allergic markers can be inconclusive in patients with VKC, flow cytometry demonstrated a local lymphocyte phenotype that can account for the clinical and histologic abnormalities of VKC.
