Background/Aim. Peripheral nervous system affection in people with lung cancer is commonly associated with paraneoplastic neuropathy. However, clinical studies evaluating the frequency, clinical, and electrophysiological characteristics of peripheral neuropathies which are not related to onconeuronal antibodies, in this, on average, older population of patients, are very rare. The aim of this study was to define the frequency, as well as clinical and electrophysiological characteristics of idiopathic neuropathies in patients suffering from lung cancer in early stages of the diseases. Methods. Clinical and electrophysiological data of 105 elderly subjects (age 63.4 ± 7.8 years) suffering from lung carcinoma who underwent extensive neurological and electrophysiological evaluation (nerve conduction studies) between 2013–2018 were estimated. Exclusion criteria were “classical” paraneoplastic neurological syndromes with onconeuronal antibodies present, as well as patients with typical known causes of peripheral neuropathy (e.g. diabetes, alcoholism, chronic renal insufficiency, vitamin deficiencies, etc.). Results. There were 19.1% patients with clinically manifest neuropathies, with additional 37.1% patients with only electrophysiological abnormalities. The most frequent pathophysiological pattern was axonal pathology (71.2%) with predominantly distal and symmetrical distribution (86.4%). Conclusion. Patients with lung cancer in the early stages of the disease show a high incidence of clinically minor damage of the nerves, according to the pattern of chronic sensomotor distal neuropathy, with predominance of axonal damage. These findings underline the importance of a detailed clinical and electrophysiological evaluation in this category of patients who are without the typical etiological factors for peripheral neuropathies since, during cancer therapy, patients undergo a series of treatments with additional risk for the development/aggravation of neuropathy. © 2020 Inst.

Background/Aim. Thymoma is the most common mediastinal tumor. The treatment procedures are based on the results from the research of retrospective studies because they are not frequent tumors. The aim of this work was to define common clinical features, therapeutic aspects, survival and recurrence free survival. Methods. This study was performed in the Clinic for Pulmonology, Clinical Centre of Serbia, Belgrade from January 1993 to December 2013. We analyzed 62 patients with histopathologically proven thymoma. The results were obtaind from medical history, physical exam, chest X-ray and/or computed tomography and operational findings or diagnostic procedure reports. Thymomas were clasiffied according to the World Health Organization classifying system, based on histopathological findings, and staged according to the Masaoka-Koga staging system. Results. There were more female (54.8%) patients. Patients were mostly in the seventh decade of life. One third (29%) of the patients were asymptomatic. Cough was the dominant symptom. Myasthenia gravis was the most common paraneoplastic syndrome (12.9%). Solitary tumor was the most common in our patients (61.3%), as well as the tumors larger than 5 cm (52.5%), and noninvasive thymomas (52.5%). The majority of patients (40%) were in the stage I of the disease. The operative approach was conducted in most of the patients (88.7%). A statistically significant difference in survival was in women, patients with solitary tumor, non-invasive thymomas, patients in the stage I of the disease, and those who were operated. The dimension of the tumor mass approached the conventional level of significance. Conclusion. In patients with thymomas, statistically significant survival rate predictors are gender, presence of solitary tumor mass, tumor invasiveness, clinical stage and surgical treatment of the disease. © 2020 Inst.
