          Abstract

          Introduction. The diagnosis of lung cancer may still be difficult due to the fact that the first symptoms very often mimic symptoms of other diseases. Case Presentation. In this paper we present two cases, in which initial diagnosis of neuroinfection delayed proper diagnosis. Conclusion. Based on our experience we concluded that neurological symptoms in the area endemic for tick-borne diseases suggesting neuroinfection require careful differential diagnosis. Moreover, neurological symptoms in heavy smokers may be associated with metastases of lung cancer.

          The impact of brain metastasis on quality of life, resource utilization and survival in patients with non-small-cell lung cancer.

          This systematic review aims to improve understanding of the burden of disease associated with brain metastases from non-small-cell lung cancer (NSCLC) in terms of survival, quality of life (QoL) and economic impact. PubMed/MEDLINE, Cochrane collaboration and EMBASE databases were searched for articles published in English from 2000 to 2014. Of 3288 abstracts retrieved, 3156 were eliminated without a full-text review. Of the 132 articles that received a full-text review, a final set of 93 articles was included in an initial literature analysis. In order to homogenize the patient populations evaluated, we included entries that were either entirely composed of NSCLC patients or that had >50% of NSCLC patients in the total study population. From the studies identified in this systematic review, median OS and PFS varied based on the type of treatment received, although whole-brain radiotherapy (WBRT) was associated with the shortest OS and PFS durations. Regimens incorporating targeted therapy in molecularly selected patients were associated with the longest OS and PFS durations. QoL findings varied among studies, generally WBRT resulted in stable or worsening QoL scores rather than improvements. Healthcare costs were increased following diagnosis of brain metastases regardless of treatment. The findings from this review highlight the need for more effective treatments of brain metastases from NSCLC that improve survival function, QoL and potentially decrease costs.

            Neoplastic meningitis.

            Neoplastic meningitis (NM) is a common problem in neuro-oncology, occurring in approximately 5% of all patients with cancer. Notwithstanding frequent focal signs and symptoms, NM is a disease affecting the entire neuraxis, and therefore staging and treatment need encompass all cerebrospinal fluid (CSF) compartments. Central nervous system staging of NM includes contrast-enhanced cranial computerized tomography or magnetic resonance imaging (MR-Gd), contrast-enhanced spine magnetic resonance imaging or computerized tomographic myelography and radionuclide CSF flow study. Treatment of NM incorporates involved-field radiotherapy of bulky or symptomatic disease sites and intra-CSF drug therapy. The inclusion of concomitant systemic therapy may benefit patients with NM and may obviate the need for intra-CSF chemotherapy. At present, intra-CSF drug therapy is confined to three chemotherapeutic agents (i.e., methotrexate, cytosine, arabinoside, and thio-TEPA) administered by a variety of schedules either by intralumbar or intraventricular drug delivery. Although treatment of NM is palliative with an expected median patient survival of 2 to 6 months, it often affords stabilization and protection from further neurologic deterioration in patients with NM.

              Extrathoracic staging of bronchogenic carcinoma.

              In assessing the value of systematic evaluation of extrathoracic extension for potentially resectable, non-small-cell bronchogenic carcinoma, a prospective study was conducted in 146 patients. The study protocol included computed tomographic (CT) scan of the brain and upper abdomen, abdominal ultrasonography, and whole-body bone scanning. The findings were matched with the clinical presentation, histologic features, and TN staging, having found out that non-small cell bronchogenic carcinoma does not follow a set pattern to metastasize. The rate of metastasis for adenocarcinoma is not only significantly larger (p less than 0.05) but it does not correlate with the TN staging, in contrast to what happens with the squamous cell carcinoma (p less than 0.01). None of the squamous cell carcinomas in intrathoracic stage I was found to metastasize. Twenty-one percent (4/19) of brain metastases were asymptomatic (three adenocarcinomas and one squamous cell carcinoma with multiorgan metastasis). Bone scanning detected metastasis in 3.4 percent (4/116) of the asymptomatic patients, and three of the four patients with asymptomatic metastasis had nonskeletal foci. In 61 percent (11/18) of patients with hepatic metastasis, we did not find organ-specific indicators to suspect it. The series showed a 7.5 percent incidence of adrenal metastasis. Our findings suggest the convenience of performing an upper abdominal CT scan and/or ultrasonography in all patients, except for those with asymptomatic stage I squamous cell carcinoma; we also suggest brain CT scanning for all patients with adenocarcinomas and large-cell carcinomas as well as for those with squamous cell carcinoma with neurologic symptoms, and whole-body bone scanning only in those patients with clinical and laboratory indication of possible bone involvement by metastatic disease.
