Stage IIIa Lung Cancer Treatment by the Combined Tomotherapy and Infusion of Autologous Peripheral-Blood-Mononuclear-Derived Lymphocytes: A Case Report of Aged Patient

Background: Lung cancer is one of the leading cancers worldwide in mortality and incidence. Treating advanced stages of lung cancer is a great problem because of high metastatic potential and low adherence to common monotherapies such as radiation or chemotherapy. In addition, monotherapy in aged patients is not always sufficiently effective. Case Report: This study presents a clinical case of a 71-year-old man with an advanced stage of lung cancer. Computed tomography (CT) of the chest revealed central tumor of the left lung and moderate mediastinal lymphadenopathy. We found circulating tumor cells (CTC) in the peripheral blood of the patient at the level of approximately 19 cells per 1 mL above the referent detection limit. The patient was treated with combined tomotherapy (eight fractions, one fraction per day except weekends) and immune cell therapy using autologous activated lymphocytes (twice during the period, on tomotherapy day #1 and day #6). The lymphocytes were obtained from peripheral blood, purified, pre-activated in culture with a specific combination of cytokines, and infused back into the patient seven days post-culture. Two months post-therapy, the tumor was reduced by 42.5% in linear dimensions according to RECIST and by 78% of volume compared to the initial values, as confirmed by CT examination. Additionally, the level of CTC in the peripheral blood dropped to the referent detection limit. Conclusions: The combination of tomotherapy and immunotherapy with activated autologous lymphocytes may result in the positive dynamics of the malignant condition in selected patients, even in aged ones.
