    ABSTRACT: In the past decade the incidence of lung cancer among women has risen, whereas among men it has slightly declined. Important differences in lung cancer have been demonstrated between men and women, although many areas still remain controversial. Some biologic differences may justify the increase in response of women to therapy for lung cancer and can partially explain the improved survival of women compared with men. We extensively reviewed the published scientific literature on this topic in order to investigate the clinical and genetic profiling underlying lung cancer in women and to use this information as a tool for medical therapy.

    ABSTRACT: The attempt to improve therapeutic results in pancreatic carcinoma has recently focused on the emerging role of molecular biology. We investigated the role of COX-2 and NF-KB expression in relation to the use of a COX-2 inhibitor (celecoxib) associated to gemcitabine and oxaliplatin in pancreatic cancer. Forty-four patients with histologically or cytologically verified, locally advanced unresectable and/or metastatic pancreatic carcinoma were eligible for the study. Thirty-three patients (75%) assumed celecoxib for all their treatment period. Treatment was repeated every 2 weeks, until there was evidence of disease progression, patient refusal, or unacceptable toxicity. Efficacy was assessed according to tumor response, clinical benefit, and time-related parameters. Five patients had a partial response, 24 had a stable disease, and 15 had a disease progression, for an overall response rate of 11%. Biochemical response rate based on CA 19.9 levels showed 2 complete and 10 partial responses, whereas 31 patients presented no changes of CA 19.9 levels. COX-2 protein expression was found in 30 tumors, while a moderate or weak/absent expression was present in 10 patients. Sixteen tumors showed a strong expression for NF-KB, 4 a moderate expression, and 5 a weak/absent expression. The use of a COX-2 inhibitor does not add any valuable activity to a gemcitabine/oxaliplatin combination, even in patients with COX-2 and NF-KB overexpressing tumors.

    ABSTRACT: Chemotherapy is of crucial importance in advanced gastric cancer patients, in order to obtain palliation of symptoms and improve survival. The most extensively studied drugs as single agents are 5-fluorouracil, cisplatin, doxorubicin, epirubicin, mitomycin C and etoposide. Newer chemotherapeutic agents include the taxanes (docetaxel and paclitaxel), oral fluoropyrimidines (capecitabine and S-1), oxaliplatin and irinotecan. Randomised trials comparing monotherapy with combination regimens have consistently shown increased response rates in favour of combination regimens, whereas only marginally improved survival rates were usually found. Several combination therapies have been developed and have been examined in Phase III trials. However, in most cases, they have failed to demonstrate a survival advantage over the reference arm. There is no internationally accepted standard of care, and uncertainty remains regarding the choice of the optimal chemotherapy regimen. The objective of this article is to review the present literature available on major Phase II - III clinical trials, in which patients suffering from advanced gastric cancer were treated with cytotoxic chemotherapy.

    ABSTRACT: The availability of different treatment options for radically resectable gastric cancer reopened the question of treatment selection and correct definition of high-risk categories. Lymphatic, blood vessel and perineural invasion (LBVI/PNI) seem to possess the necessary potential to provide useful information for the clinical management of this disease. Seven hundred and thirty-four patients with advanced gastric cancer who underwent curative gastrectomy were analysed according to the presence of LBVI/PNI. Patients were divided into two groups: group A for patients with LBVI/PNI (189 patients 26%) and group B for patients without LBVI/PNI (545 patients, 74%). The disease-free survival (DFS) for patients in group A was 32.1 months, whereas it was not reached for patients in group B (P=0.0001); the median overall survival was 45.5 months for patients in group A, whereas it was not reached for patients in group B (P=0.0001). At multivariate analysis, the presence of LBVI/PNI appeared an independent prognostic factor for DFS and OS. Our results were confirmed in subgroup analysis, separately considering stage I and early gastric cancer patients with and without LBVI/PNI. Taken together, our findings suggest the importance of LBVI/PNI in gastric cancer as it may provide additional information for identifying patients at high risk, who may be candidates for further medical treatment after or before surgery.

    ABSTRACT: The recent elucidation both of the mechanisms involved in pancreatic cancer carcinogenesis and the related molecular events, has led to several distinct therapeutic advances, including many novel target agents, such as monoclonal antibodies against EGFR, EGFR-tyrosine kinase inhibitors, monoclonal antibody against VEGF, farnesyl transferase inhibitors, matrix metalloproteinase inhibitors, COX 2 inhibitors, and the development of gene therapy to target pancreatic cancer. This review highlights recent findings in the treatment of pancreatic cancer by using these novel therapeutic approaches.

    ABSTRACT: We hypothesised that anemia could represent an important prognostic factor and perioperative blood transfusions do not reduce the risk of relapse. In order to explore this topic, we assessed the correlation of preoperative anemia and blood transfusions with survival in patients with resected non-small cell lung cancer (NSCLC). Patients who underwent radical surgery for NSCLC at the Department of Thoracic Surgery of Università Politecnica delle Marche from January 1996 through December 2001, were included in our study. Four hundred and thirty-nine patients were eligible for our analysis. Survival appeared worse in patients with haemoglobin (Hb) < or =10 g/dl versus Hb >10 g/dl (p=0.012). Stratifying patients in three groups on their Hb level (group 1: Hb < or =10 g/dl; group 2: Hb=10-12 g/dl; group 3: Hb > or =12 g/dl), we observed a worse prognosis in patients with lower Hb levels, too (p=0.0325) and also in the transfused population (p=0.046). At multivariate analysis, only the age of patients, pathological stage and Hb levels resulted indicators of prognosis. Our results suggested that anemia could represent an important prognostic factor in resected NSCLC and correction of anemia in the perioperative setting does not reduce the risk of relapse.

    ABSTRACT: Many authors agree on the idea that the affective and behavioural characteristic of a certain type of family encourages the use of the body as a primary means of communication with others. This way of communicating has usually been acquired during childhood and later, in the adult life, it appears again in the different social contests. Some authors like Alby, Levy, Baker, Parker, Lipscombe, Marcelli, Bianchi and others focus on this type of family interaction and the single characteristic of the personalities of each family member. These authors describe some relationship patterns used by hypochondriac patient such as: avoiding unpleasant situations, blaming others, adopt a sick-role as a way of controlling the relationship between existential events and somatic symptoms; relationship with physicians and the need to confirm her/himself.

    ABSTRACT: Colorectal cancer is the most common gastrointestinal tumor in Western countries and is increasing in elderly patients. In recent years, new treatments based on the use of 5-fluorouracil associated with oxaliplatin or CPT-11 have shown promising activity. The aim of the present study was to analyze the tolerability and activity of chemotherapy with 5-fluorouracil plus oxaliplatin or CPT-11 in elderly patients with advanced colorectal cancer. Patients aged 70 years or older with advanced colorectal cancer were treated with 5-fluorouracil (400 mg/m2 in bolus and 600 mg/m2 in a 22-hr continuous infusion on days 1-2) plus folinic acid (100 mg/m2) associated to oxaliplatin (85 mg/m2 on day 1, FOLFOX regimen) or CPT-11 (180 mg/m2 on day 1, FOLFIRI regimen), every 14 days. Twenty-nine patients with a median age of 76 years (range, 70-82) were treated with FOLFOX or FOLFIRI as first-line chemotherapy for metastatic disease. We observed a partial response in 8/29 (27.6%), stable disease in 11/29 (37.9%) and progressive disease in 10/29 (34.5%). Median survival was 21 months; 1-year survival probability was 89.8%. Grade III leukopenia was observed in 2/29 (7%) patients and grade III diarrhea in 1/29 patients. No other grade III-IV toxicity was observed. FOLFOX and FOLFIRI appear to be active and well tolerated regimens for elderly patients with advanced colorectal cancer.
