ReviewInflammation in lung carcinogenesis: new targets for lung cancer chemoprevention and treatment.
Lung carcinogenesis is a complex process involving the acquisition of genetic mutations that confer cancer development and the malignant phenotype, and is critically linked to apoptosis resistance, unregulated proliferation, invasion, metastasis, and angiogenesis. Epithelial mesenchymal transition (EMT) in cancer is an unregulated process in a host environment with deregulated inflammatory response that impairs cell-mediated immunity and permits cancer progression. ⋯ Clinical trials are underway to evaluate COX-2 inhibitors as adjuvants to chemotherapy in patients with lung cancer and to determine efficacy in prevention of bronchogenic carcinoma. The understanding of molecular mechanisms involved in inflammation and lung carcinogenesis provide insight for new drug development that target reversible, non-mutational events in the chemoprevention and treatment of lung cancer.

Palliative chemotherapy in elderly patients with common metastatic malignancies: A Hellenic Cooperative Oncology Group registry analysis of management, outcome and clinical benefit predictors.
Cancer in the elderly is a common health issue in developed societies. We sought to present epidemiology, management and outcome data on fit elderly patients with common metastatic cancers and to identify predictors of clinical benefit from palliative chemotherapy. ⋯ Our data indicate that relatively fit elderly patients with advanced cancer safely tolerate modern chemotherapy and enjoy disease control in a manner comparable to younger patients. Our GAP score, if further validated, offers promise for geriatric application in combination to comprehensive geriatric assessment tools for the optimisation of palliative therapy on an individualised basis.

Multicenter StudyShall we operate? Preoperative assessment in elderly cancer patients (PACE) can help. A SIOG surgical task force prospective study.
A number of elderly cancer patients do not receive standard surgery for solid tumors because they are considered unfit for treatment as a consequence of inaccurate estimation of the operative risk. To tailor treatment to onco-geriatric series, oncologists are now beginning to use a comprehensive geriatric assessment (CGA). This study investigates the value of an extended CGA in assessing the suitability of elderly patients for surgical intervention. ⋯ PACE represents a valuable tool in enhancing the decision process concerning the candidacy of elderly cancer patients for surgical intervention and can reduce inappropriate age-related inequity in access to surgical intervention. It is recommended that PACE be used routinely in surgical practice.

ReviewDepression and cancer: an unexplored and unresolved emergent issue in elderly patients.
Despite the high prevalence of depressive disorders in cancer patients and elderly people, the topic of depression in elderly cancer patients still remains unexplored. This emerges from a systematic review of the literature conducted to investigate issues of depression, diagnosis, pathogenesis, treatment and their complex neuroimmunobiological interactions. Indeed, it becomes apparent that depression in elderly patients with cancer may have a peculiar phenomenology. ⋯ Immune dysfunction may represent a common pathogenic ground of depression, cancer and aging. This may have important implications for treatment. In the near future, we need to develop validated mood disorder diagnoses and verify antidepressant treatment efficacy for elderly cancer patients with depression in order to improve their clinical outcome and quality of life.

The incidence of most types of cancers is age-dependent and progressive ageing is rapidly increasing the number of elderly people who need treatment for cancer. It is an ethical dilemma how aggressive one should be when it comes to treating cancer in the older population. Presumed fear of increased postoperative morbidity and mortality often results in delivery of sub-optimal cancer surgery. ⋯ In this review article we take into consideration physiology of the aged and tools available to assess surgical risks in elderly patients, in the aim of increasing awareness on optimising surgical management of elderly patients with cancer. MEDLINE and EMBASE.com (search terms: "elderly", "preoperative", "surgery"), bibliographies of articles retrieved and the authors' reference files have been used as data sources. Independent extraction has been performed by the authors using predefined criteria, including study quality indicators.
