Pathophysiology, clinical manifestations and supportive care of metastatic brain cancer.

Brain metastases (BrM) are tumours that originate in tissues outside the central nervous system and spread secondarily to involve mainly the brain. The management of patients with cerebral metastases is complex, costly, and in some instances controversial. Furthermore, even in patients with widespread systemic cancer, the symptoms of the disease are often controllable while the symptoms of the BrM may be disabling. The treatment of BrM is one of the few areas of neuro-oncology where real progress has been made in the last twenty years. Moreover, the costs of managing this disease are rising, as therapies become more intensive and the number of patients with BrM increases. Modern neuroradiological imaging techniques, which are able to discover BrM earlier in the course of systemic cancer, and the greater efficacy of specific treatments, which lengthens survival, have increased the prevalence. The aggressive treatment of BrM may add some benefits to the patient, but its excessive cost leads to the necessity for accurate cost-effectiveness analysis. The latter begins with a complete understanding of the disease: its diagnosis, natural history and results of various modalities of treatment. While the development of BrM usually indicates a poor prognosis for the patient, advances in supportive care have made it possible to reverse most of the neurological symptoms and to give patients a meaningful extension of useful life.

[Gastric lymphoma. Anatomo-clinical and prognostic correlations].

In order to assess the prognostic value of some clinicopathological factors of Gastric Lymphoma the authors reviewed 37 consecutive cases observed between 1973 and 1985 with 48 months follow up at least. Age, sex, gross features, site, histological subtype, depth of gastric wall invasion, regional lymph nodes involvement weren't useful parameters. Notable difference exists in survival according to the treatment carried out (surgery and chemoradiotherapy 100% alive & well, surgery and chemotherapy 29% a&w, surgery 17% a&w). The authors compared inflammatory cell population reactive to neoplasm to survival as possible meaningful parameter.

Depolarized expression of episialin (EMA, MUC1) in lung adenocarcinoma is associated with tumor progression.

Carcinoma cell detachment is an important step in tumor progression and metastasis. Episialin (EMA), if expressed throughout the entire cell surface, may inhibit cell-cell and cell-matrix adhesion. We investigated whether the cellular distribution of episialin in non-small cell lung cancer (NSCLC) is associated with tumor progression. We evaluated the expression of episialin by immunohistochemical staining, in surgical specimens from 122 adenocarcinomas and 99 squamous cell carcinomas. Episialin was present in most NSCLC, with a higher percentage of immunoreactive neoplastic cells in adenocarcinoma than in squamous cell carcinoma (p = 0.0001). In adenocarcinoma the depolarized pattern was significantly associated with nodal metastasis (p = 0.005) and with advanced stage (p = 0.007). In conclusion, nodal metastasis and advanced pathological stage in adenocarcinoma are associated with a depolarized cellular distribution of episialin, suggesting a possible involvement of the molecule in cancer metastasis.
