Abstract
BACKGROUND KRAS wild-type mutational status is necessary but not sufficient to get benefit from epidermal growth factor receptor inhibition. Predictive markers are currently being evaluated. In this study, we investigated early hypomagnesemia as a predictor of efficacy and outcome in terms of time to progression (TtP) and overall survival (OS) in a cohort of patients affected by advanced colorectal adenocarcinoma KRAS wild-type cetuximab-treated. PATIENTS AND METHODS One hundred and forty-three patients affected by stage IV colorectal adenocarcinoma KRAS wild type receiving cetuximab + irinotecan (CTX+IRI) as third-line anticancer treatment and resistant to oxaliplatin- and irinotecan-based chemotherapy were retrospectively included. Magnesium plasma levels were measured before the first day and 7, 14, 21 and 28 days after CTX+IRI infusion. RESULTS The median magnesium basal value showed a statistically significant decrease after the start of CTX+IRI treatment (at 28 days, P < 0.0001). Patients with an early decrease of magnesium levels >50% compared with the basal level had a higher tumor response rate (55.8% versus 16.7%, P < 0.0001), a longer TtP (6.3 versus 3.6, P < 0.0001) and a longer median OS (11.0 versus 8.1, P = 0.002). CONCLUSIONS We have shown that early hypomagnesemia could be a predictor of efficacy and outcome in those patients. Magnesium circulating level is an easy and inexpensive biomarker to routinely be detected in patients treated with cetuximab.

Abstract
Chondromas are rare primary spine tumors. Only 12 cases of chondromas located in the cervical spine have been reported in the literature up to now. The authors report a case of a cervical periosteal chondroma in a 38-year-old man presenting with neck pain and a syndrome of spinal cord compression. Magnetic resonance imaging revealed a lesion that was hypo- or isointense on T1-weighted images and iso-hyperintense on T2-weighted images. Administration of Gd-DPTA resulted in margin enhancement on T1-weighted images. CT scans revealed a hyperdense calcified lesion arising from the internal surface of C5 right hemi-lamina. The patient underwent a right C5 hemi-laminectomy, with complete en-bloc removal of the lesion. The authors emphasize that early identification of the initial lesion should be coupled with total surgical resection, as a definitive treatment, in order to prevent malignant transformation.

Abstract
There is increasing evidence that the Let-7 microRNA (miRNA) exerts an effect as a tumor suppressor by targeting the KRAS mRNA. The Let-7 complementary site (LCS6) T>G variant in the KRAS 3'-untranslated region weakens Let-7 binding. We analyzed whether the LCS6 variant may be clinically relevant to patients with metastatic colorectal cancer (MCRC) treated with anti-epidermal growth factor receptor (EGFR) therapy. LCS6 genotypes and KRAS/BRAF mutations were determined in the tumor DNA of 134 patients with MCRC who underwent salvage cetuximab-irinotecan therapy. There were 34 G-allele (T/G+G/G) carriers (25%) and 100 T/T genotype carriers (75%). G-allele carriers were significantly more frequent in the KRAS mutation group than in patients with KRAS wild type (P=0.004). In the 121 patients without BRAF V600E mutation, overall survival (OS) and progression-free survival (PFS) times were compared between carriers of the LCS6 G-allele genotypes and carriers of the wild-type T/T genotype. LCS6 G-allele carriers showed worse OS (P=0.001) and PFS (P=0.004) than T/T genotype carriers (confirmed in the multivariate model including the KRAS status). In the exploratory analysis of the 55 unresponsive patients with KRAS mutation, LCS6 G-allele carriers showed adverse OS and PFS times. These findings deserve additional investigations as they may open novel perspectives for the treatment of patients with MCRC.

Abstract
Background: KRAS codons 12 and 13 mutations predict resistance to anti-EGFR monoclonal antibodies (moAbs) in metastatic colorectal cancer. Also, BRAF V600E mutation has been associated with resistance. Additional KRAS mutations are described in CRC. Methods: We investigated the role of KRAS codons 61 and 146 and BRAF V600E mutations in predicting resistance to cetuximab plus irinotecan in a cohort of KRAS codons 12 and 13 wild-type patients. Results: Among 87 KRAS codons 12 and 13 wild-type patients, KRAS codons 61 and 146 were mutated in 7 and 1 case, respectively. None of mutated patients responded vs 22 of 68 wild type (P=0.096). Eleven patients were not evaluable. KRAS mutations were associated with shorter progression-free survival (PFS, HR: 0.46, P=0.028). None of 13 BRAF-mutated patients responded vs 24 of 74 BRAF wild type (P=0.016). BRAF mutation was associated with a trend towards shorter PFS (HR: 0.59, P=0.073). In the subgroup of BRAF wild-type patients, KRAS codons 61/146 mutations determined a lower response rate (0 vs 37%, P=0.047) and worse PFS (HR: 0.45, P=0.023). Patients bearing KRAS or BRAF mutations had poorer response rate (0 vs 37%, P=0.0005) and PFS (HR: 0.51, P=0.006) compared with KRAS and BRAF wild-type patients. Conclusion: Assessing KRAS codons 61/146 and BRAF V600E mutations might help optimising the selection of the candidate patients to receive anti-EGFR moAbs.

Abstract
4058 Background: KRAS and BRAF mutations are associated with resistance to anti-EGFR monoclonal antibodies. EGFR Intron-1 (CA)n genotype has been suggested to influence the activity of cetuximab. Methods: We retrospectively assessed KRAS and BRAF mutational status and EGFR Intron-1 (CA)n genotypes in 117 irinotecan-refractory EGFR-positive mCRC patients treated with cetuximab plus irinotecan. We defined short (S) and long (L) allelic variants those presenting < and ≥17 CA repeats respectively. Among KRAS wild-type patients, we investigated the association between BRAF mutational status and EGFR Intron-1 genotype and treatment outcome in terms of RR and PFS. Results: Among 66 (56%) KRAS wild-type patients, BRAF V600E mutation was detected in 9 (14%) patients. BRAF wild-type patients reported improved RR (0/9, 0% vs 19/57, 33%, p = 0.04) and PFS (3.3 vs 5.1 months, p = 0.076; HR = 0.54 [95%CI: 0.18–1.09]) in comparison with BRAF-mutated. EGFR Intron-1 L/L genotype was detected in 13 (20%) KRAS wild-type patients. Objective responses were reported in 1/13 (8%) EGFR Intron-1 L/L patients and in 18/53 (34%) S/L or S/S patients (p = 0.061). Significantly longer PFS was observed among EGFR Intron-1 S/L or S/S patients (5.3 vs 3.3 months, p = 0.0062; HR = 0.45 [95%CI: 0.14–0.72]). Among 57 KRAS and BRAF wild-type patients, 1/11 (9%) EGFR Intron-1 L/L patients and 18/46 (39%) S/L - S/S patients responded to treatment (p = 0.058), achieving median PFS of 3.7 and 5.4 months, respectively (p = 0.022; HR = 0.48 [95%CI: 0.15–0.87]). Conclusions: In KRAS wild-type patients, BRAF mutations are confirmed to predict resistance to cetuximab treatment. EGFR Intron-1 allelic variants are promising markers of benefit in patients with both KRAS and BRAF wild-type and may help to better select mCRC patients candidate to receive cetuximab-containing treatment.

Abstract
4126 Background: Previous reports have suggested that mucinous colorectal adenocarcinomas have a poorer prognosis than nonmucinous colorectal adenocarcinomas. This retrospective analysis was conducted to explore whether mucinous carcinoma (MC) is associated with a worse prognosis than nonmucinous carcinoma (NMC) for patients with Dukes B2 and C radically resected colon cancer. Methods: We investigated 1,006 unselected patients who underwent curative surgery for sporadic colon cancer and followed up at six Oncology Department between 1998 and 2006. Univariate and multivariate analyses were performed to determine prognostic factors of survival. Results: MC accounted for 17.9% (n=180) of all colon carcinomas. Patient characteristics were as follows. MC: M/F 104/76; median age, 68 (range, 28–97); pT1/2/3/4, 1/4/153/22; Dukes B2/C 98/82; invasion 26 (14%); ≥12 examined lymph nodes, 115 (64%); adjuvant chemotherapy, 110 (61%). NMC: M/F 445/381; median age, 68 (range, 29–95); pT1/2/3/4, 9/51/715/51; Dukes B2/C 384/442; invasion 199 (24%); ≥12 examined lymph nodes, 499 (60%); adjuvant chemotherapy, 545 (66%). MC were more frequently located in the proximal colon (54.4% versus 34.6% for NMC; p<0.001). No difference between MC and NMC in disease-free survival (hazard ratio, HR 1.01; 95% CI, 0.76–1.36; p=0.92) and overall survival (HR 1.05; 95% CI, 0.74–1.49; p=0.78) was found. After stratification by stage of disease, MC and NMC had no statistically significant difference in 5-year disease-free survival (Dukes B2: 79.1% and 78.1%, respectively, p=0.86; Dukes C: 53.8% and 56.2%, respectively, p=0.58) and overall survival (Dukes B2: 84.2% and 85.5%, respectively, p=0.80; Dukes C: 68.0% and 67.3% p=0.52). Multivariate analysis using the Cox proportional hazards model showed that the clinically significant prognostic factors were stage at diagnosis (p<0.0001), grading (p<0.0001), and number of lymph node examined (p=0.0002) in the specimen. Conclusions: In this preliminary analysis, patients with mucinous histology who underwent surgery with curative intent for stage Dukes B2 and C colon cancer had similar prognosis compared to NMC. No significant financial relationships to disclose.

Abstract
In the present study we investigated the potential role of Toll-like receptor 4 (TLR-4) Asp299Gly and Thr399Ile polymorphisms as risk factors in the development of gastric cancer. TLR-4 Asp299Gly and Thr399Ile polymorphisms were investigated in 171 Italian patients with sporadic gastric cancer and in 151 controls. Unconditional regression (odds ratio and 95% confidence intervals) were used to investigate the association of the studied polymorphisms with gastric cancer. TLR-4 Thr399Ile polymorphism is linked with an increased susceptibility to gastric cancer (P = 0.023 and hazard ratio = 3.62). No significant association for TLR-4 Asp299Gly polymorphism was found. In the subgroup of patients with intestinal-type gastric cancer, a significant risk of gastric cancer was associated with TLR-4 Thr399Ile genotype (P = 0.006). Our results demonstrated that TLR-4 Thr399Ile polymorphism is linked with an increased susceptibility to gastric cancer. An increased risk for intestinal gastric cancer in carriers of the TLR4 Thr399Ile allele was observed. Future epidemiological studies should consider the possible interactions between proinflammatory genotypes (such as TLR and interleukin-1R polymorphisms) and other risk factors for cancer such as dietary habits and/or exposure to environmental carcinogens.

Abstract
No established second-line chemotherapy is available for patients with advanced gastric cancer failing to respond or progressing to first-line chemotherapy. However, 20–40% of these patients commonly receive second-line chemotherapy. We evaluated the influence of clinico-pathologic factors on the survival of 175 advanced gastric cancer patients, who received second-line chemotherapy at three oncology departments. Univariate and multivariate analyses found five factors which were independently associated with poor overall survival: performance status 2 (hazard ratio (HR), 1.79; 95% CI, 1.16–2.77; P=0.008), haemoglobin ⩽11.5 g l−1 (HR, 1.48; 95% CI, 1.06–2.05; P=0.019), CEA level >50 ng ml−1 (HR, 1.86; 95% CI, 1.21–2.88; P=0.004), the presence of greater than or equal to three metastatic sites of disease (HR, 1.72; 95% CI, 1.16–2.53; P=0.006), and time-to-progression under first-line chemotherapy ⩽6 months (HR, 1.97; 95% CI, 1.39–2.80; P<0.0001). A prognostic index was constructed dividing patients into low- (no risk factor), intermediate- (one to two risk factors), or high- (three to five risk factors) risk groups, and median survival times for each group were 12.7 months, 7.1 months, and 3.3 months, respectively (P<0.001). In the absence of data deriving from randomised trials, this analysis suggests that some easily available clinical factors may help to select patients with advanced gastric cancer who could derive more benefit from second-line chemotherapy.

Abstract
We investigated the association between thymidylate synthase (TS) germline polymorphisms and response to 5-fluorouracil-based chemotherapy in 80 patients with liver-only metastatic colorectal cancer (MCRC). The tandem repeat polymorphism (VNTR) in TS 5′-untranslated region (5′-UTR), which consists of two (2R) or three (3R) 28-bp repeated sequences, with or without a G/C nucleotide change in 3R carriers (3G or 3C) and a 6-bp insertion/deletion (6+/6−) in the TS 3′-UTR, was studied. The distinction between high (2R/3G, 3C/3G and 3G/3G) and low (2R/2R, 2R/3C and 3C/3C) TS expression genotypes according to the 5′-UTR VNTR+G/C nucleotide change showed significant association with tumour response (P=0.01). In particular, high TS expression genotypes were found in 8 out of 34 patients (23.5%) with complete or partial response and in 24 out of 46 patients (52%) with stable disease and disease progression. Liver-only MCRC patients are a homogeneous and clinical relevant subgroup that may represent an ideal setting for studying the actual influence of TS polymorphisms.

Abstract
BACKGROUND We investigated whether an endogastric capsule (EC) may be a valuable tool for collecting DNA from exfoliated cells from the gastric mucosa and for carrying out an analysis of promoter methylation status of the E-cadherin (CDH1) gene in poorly differentiated, diffuse gastric cancer (DGC). MATERIAL AND METHODS Consecutive patients with a confirmed diagnosis of poorly differentiated DGC underwent collection of gastric juice by EC. Subjects without cancer and premalignant lesions were also accrued as controls. The samples of gastric juice were processed for DNA isolation and amplification. Then they were used for analysis of CDH1 promoter hypermethylation. RESULTS The procedure successfully allowed the analysis of CDH1 promoter hypermethylation in 20 patients and 14 controls. This pilot study showed feasibility of the procedure and a significantly different CDH1 promoter hypermethylation status between DGC patients and controls was detected. CONCLUSIONS The EC may represent an innovative and noninvasive tool for the analysis of a specific epigenetic change in DGC patients. Our findings deserve additional studies as this method may represent a cost-effective tool for early detection of sporadic as well as hereditary DGC in CDH1 germline mutations carriers.

Abstract
21142 Introduction: Previous studies on the association between interleukin-1 (IL-1) genetic polymorphisms and the risk of gastric cancer have produced conflicting results. The purpose of this study was to examine the association between IL-1 genotype and gastric cancer by systematically reviewing the original studies. Materials and Methods: We searched the MEDLINE, CENTRAL, and PubMed databases (last research performed on July 2005) and reviewed cited references to identify relevant studies. Search key words were: gastric cancer (OR stomach cancer OR gastric adenocarcinoma OR stomach adenocarcinoma) and IL-1 (OR IL1). The literature review identified 23 titles that met the search criteria. Data from 15 articles that investigated the association between any of IL-1B-511 and IL-1B-31 polymorphisms and gastric cancer met the inclusion criteria, and they were included in the meta-analysis. Eight studies evaluated the role of IL-1B-511, four the role of IL- 1B-31 and three investigated both IL-1B-511 and IL-1B-31. Results: By pooling all the studies identified, our study shows that individuals IL-1B-31T carrier have got an increased risk developing gastric cancer (OR of 1.25; 95% CI 1.06–1.47) in particular in Caucasian sub-group (OR of 1.41; 95% CI 0.97–2.05). IL-1B-31CC genotype confers a decreased risk (OR of 0.80; 95% CI 0.68–0.95) especially in Caucasian population (OR of 0.71; 95% CI 0.49–1.03) compared to Asians (OR of 0.83; 95% CI 0.69–0.99). This association might be explained with the well-known near complete linkage disequilibrium between IL1B-511T and IL1B-31C polymorphism. Furthermore our results suggest a strong association between IL1B-511T polymorphism and gastric cancer risk only in Caucasians and not in Asians. Conclusions: In conclusion, although affected by the common bias of each epidemiologic studies, this pooled analysis suggests that IL1B-511T polymorphism is associated with an increased risk of developing gastric cancer in Caucasian population.

Abstract
15169 Background: Currently, there is no established second-line chemotherapy for pts with advanced gastric cancer who failed to respond or progressed after a first-line chemotherapy. Many of these pts still have a good performance status or have symptoms to be palliated at the time of first-line failure and are candidates for second-line chemotherapy. However, phase II trials demonstrate divergent results about pts more likely to benefit from second-line chemotherapy. We retrospectively analyzed the influence of various clinicopathologic factors on the survival of pts treated with second-line chemotherapy. Methods: Analysis is based on the data of 169 pts consecutively treated at 3 oncology department with a second-line chemotherapy. Univariate and multivariate analyses were performed to determine prognostic factors of survival. The variable used for analysis were: sex, age, ECOG performance status, a weight loss > 5 Kg in the last month; site of primary tumor, histopathology; hemoglobin, serum albumin, and CEA levels, number and site of metastatic disease, response to and time-to-progression (TTP) with the first- line chemotherapy. Results: The variables predictive of better survival were: ECOG PS 0–1 (p<0.001), no weight loss (p=0.001), hemoglobin level > 10 g/dl (p=0.01), CEA level <50 U/ml (p<0.02), number of metastatic sites = 2 (p=0.002), TTP of the first-line chemotherapy > 4 months (p=0.008). Peritoneal carcinomatosis was predictive of poor survival only when associated with one or more signs or symptoms as vomiting, anorexia, abdominal pain, ascites(p=0.03). Four factors were independently associated with better overall survival: ECOG PS 0–1 (p=0.002; HR 0.46; CI 95%, 0.29–0.75), CEA level <50 U/ml (p=0.008; HR 0.54; CI 95%, 0.35–0.85), one or two metastatic sites of disease (p=0.01; HR 0.58; CI 95%, 0.39–0.88), and TTP of the first-line chemotherapy > 4 months (p=0.02; HR 0.66; CI 95%, 0.45–0.95). Conclusions: In the absence of data deriving from randomized, controlled, clinical trials, this analysis suggests that some clinical factors may help clinicians to better select groups of pts with gastric cancer more likely to benefit from a second-line chemotherapy.

Abstract
The primary end point of the study was the analysis of associations between polymorphisms with putative influence on 5-fluorouracil/irinotecan activity and progression-free survival (PFS) of patients with advanced colorectal cancer treated with first-line FOLFIRI chemotherapy. Peripheral blood samples from 146 prospectively enrolled patients were used for genotyping polymorphisms in thymidylate synthase (TS), methylenetetrahydrofolate reductase (MTHFR), excision repair cross-complementation group-1 (ERCC 1) xeroderma pigmentosum group-D (XPD), X-ray cross-complementing-1 (XRCC 1), X-ray cross-complementing-3 (XRCC 3) and uridine diphosphate-glucuronosyltransferases-A1 (UGT1 A1). TS 3'-UTR 6+/6+ and XRCC3-241 C/C genotypes were associated with adverse PFS. Hazard ratio for PFS achieved 2.89 (95% confidence interval=1.56-5.80; P=0.002) in 30 patients (20%) with both risk genotypes. Risk for Grade III-IV neutropenia was significantly associated with UGT1A1*28 7/7 genotype. These promising findings deserve further investigations and their validation in independent prospective studies.

Abstract
AIM OF THE STUDY To compare clinical and ultrasound (US) changes induced in cold thyroid nodules by US-guided percutaneous laser ablation (PLA) versus follow-up or levothyroxine (LT4) suppressive therapy. METHODS 62 patients randomly assigned to a single PLA (Group 1), LT4 (Group 2), or follow-up (Group 3). Entry criteria: euthyroid patients with a solid thyroid nodule >5 mL and benign cytological findings. TREATMENT Group 1: PLA was performed with a 1.064 mum neodymium yttrium-aluminum-garnet laser with output power of 3 W for 10 minutes; Group 2: the LT4 dose was adjusted to induce thyrotropin suppression; Group 3: no treatment. RESULTS In Group 1 a significant nodule reduction was found 6 and 12 months after PLA (delta volume: -42.7 +/- 13.6%; p = 0.001). A reduction >50% was found in 33.3% of cases. In Group 2 a nonsignificant nodule shrinkage was observed. A nonsignificant volume increase was observed in Group 3. Improvement of local symptoms was registered in 81.2% of patients in Group 1 vs. 13.3% in Group 2 and 0.0% in Group 3 ( p = 0.001). No complications were noted. CONCLUSIONS A single PLA induced significant volume reduction and improvement of local symptoms. PLA was more effective than LT4. Follow-up was associated with nodule growth and progression of local symptoms. PLA should be considered a potential mini-invasive alternative to surgery in symptomatic patients with benign cold thyroid nodules.

Abstract
Hereditary diffuse gastric cancer (HDGC) is a cancer predisposition syndrome caused by germline mutation of the gene encoding the tumour-suppressor E-cadherin (CDH1). We describe the search for CDH1 mutations in 36 new diffuse gastric cancer families. All 16 CDH1 exons, neighbouring intronic sequence and an essential promoter region were screened by DNA sequencing. We detected nine different mutations, seven of which were novel. Of the seven novel mutations, five were identified in families who met the IGCLC clinical criteria for HDGC. Two mutations resulted in a premature stop codon and truncation of the protein. Three mutations affected splice sites; two of the splice-site mutations were shown by RT-PCR to disturb normal CDH1 splicing, while the third splice-site mutation was present in two unrelated HDGC families. The remaining two mutations resulted in amino acid substitutions and impaired the ability of E-cadherin protein to form cellular aggregates and suppress invasion in vitro. Together with the occurrence of extra-gastric tumours such as lobular breast and colorectal cancer, these findings further extend the types of CDH1 mutations and the spectrum of tumours associated with HDGC.

Abstract
PURPOSE To evaluate the effect of the anti-cancer drug carboplatin on plasma concentrations and urinary excretion of L-carnitine (LC) and its main ester, acetyl-L-carnitine (ALC), in cancer patients. METHODS Plasma and urine concentrations of LC and ALC from 11 patients on carboplatin therapy (1 h intravenous infusion; AUC dose 4.8 +/- 1.1 mg/ml min) in combination with docetaxel, paclitaxel or vinorelbine, were determined by high-performance liquid chromatography with fluorimetric detection. RESULTS Before carboplatin therapy, the mean +/- SD plasma concentrations of LC and ALC were 47.8 +/- 10.9 and 7.04 +/- 1.04 nmoles/ml, respectively, and remained constant throughout the entire study period. In contrast, urinary excretion of LC and ALC, increased significantly during the chemotherapy from 115 +/- 105 to 480 +/- 348 micromoles/day (P < 0.01) and from 41 +/- 41 to 89 +/- 52 micromoles/day (P < 0.05) for LC and ALC, respectively, subsequently reverting to normal 6 days after the end of chemotherapy. Similarly, the renal clearance of LC and ALC increased substantially during chemotherapy from 1.67 +/- 1.43 to 9.05 +/- 9.52 ml/min (P < 0.05) and from 4.02 +/- 4.51 to 7.97 +/- 5.05 ml/min (P = not significant) for LC and ALC, respectively, reverting to normal 6 days after the end of chemotherapy. Plasma concentrations and urinary excretion of glucose, phosphate and urea nitrogen and creatinine clearance, however, were not affected by carboplatin therapy, indicating no impaired kidney function. CONCLUSION Treatment with carboplatin was associated with a marked urinary loss of LC and ALC, most likely due to inhibition of carnitine reabsorption in the kidney.

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
BACKGROUND Elderly patients have been often excluded from or underrepresented in the study populations of combination chemotherapy trials. The primary end point of this study was to determine the response rate and the toxicity of the weekly oxaliplatin, 5-fluorouracil and folinic acid (OXALF) regimen in elderly patients with advanced gastric cancer. The secondary objective was to measure the time to disease progression and the survival time. METHODS Chemotherapy-naive patients with advanced gastric cancer aged 70 or older were considered eligible for study entry. Patients received weekly oxaliplatin 40 mg/m2, fluorouracil 500 mg/m2 and folinic acid 250 mg/m2. All drugs were given intravenously on a day-1 schedule. RESULTS A total of 42 elderly patients were enrolled. Median age was 73 years and all patients had metastatic disease. The response rate according to RECIST criteria was 45.2% (95% CIs: 30%-56%) with two complete responses, 17 partial responses, 13 stable diseases and 10 progressions, for an overall tumor rate control of 76.2% (32 patients). Toxicity was generally mild and only three patients discontinued treatment because of treatment related adverse events. The most common treatment-related grade 3/4 adverse events were fatigue (7.1%), diarrhoea (4.8%), mucositis (2.4%), neurotoxicity (2.4%) and neutropenia (4.8%). The median response duration was 5.3 months (95% CIs: 2.13 - 7.34), the median time to disease progression was 5.0 months (95% CIs: 3.75 - 6.25) and the median survival time was 9.0 months (95% CIs: 6.18 - 11.82). CONCLUSION OXALF represents an active and well-tolerated treatment modality for elderly patients with locally advanced and metastatic gastric cancer.

Abstract
OBJECTIVES Although several evidences have demonstrated a synergistic activity of 5-fluorouracil with irinotecan and oxaliplatin, thus explaining the use of this drug combination in the first-line treatment of advanced colorectal cancer, the need for the reintroduction of 5-FU in the second-line setting is more questionable. METHODS We retrospectively evaluated the outcome of patients developing progressive disease while on an infusional 5-FU-based front-line chemotherapy and subsequently treated with one of the four following chemotherapy regimens: irinotecan, oxaliplatin and irinotecan or oxaliplatin both combined with the de Gramont schedule (LV5-FU2). RESULTS 225 patients (137 males and 88 females), were eligible for analysis. Second-line chemotherapy consisted of irinotecan in 79 patients (35%, group A), oxaliplatin in 47 patients (21%, group B), irinotecan with LV5-FU2 in 53 patients (24%, group C) and oxaliplatin with LV5-FU2 in the remaining 46 cases (20%, group D). The response rate to second-line chemotherapy was obtained in 6/79 patients (8%) in group A, in 4/47 patients (9%) in group B, in 11/53 patients (21%) in group C and in 10/46 patients (22%) in group D (p = 0.04). CONCLUSIONS These data suggest that reintroduction of 5-FU could increase irinotecan and oxaliplatin activity in patients progressing during a 5-FU-based first-line chemotherapy.

Abstract
The presence of metastatic lesions confined to the caudate lobe (CL or segment I) is quite a rare event. Even more rare is the decision to perform an isolate CL resection. Segmental resection in the liver is justified by the evidence that primary and secondary lesions, in early stage, are confined to the originating segment, and therefore a segmentectomy can be considered for the CL as well. Anatomy of the CL was deeply studied through the years since the surgical approach to this liver segment requires a detailed knowledge of its surgical anatomy and only after 1985 the surgical technique for CL isolate resection was established. We report our experience with 1 case of isolate colo-rectal metastasis confined to the caudate lobe and describe the surgical technique employed.

Abstract
The aim of our analysis was to assess retrospectively the effect on local relapse, overall survival (OS) and disease-free survival (DFS) of a limited or an extended lymphadenectomy in radically resected gastric cancer patients. This study was performed in order to identify a subgroup of patients possibly not benefiting from a therapeutic approach such as chemoradiation therapy. We divided our patients into two groups according to lymphadenectomy type: group A for limited (<25 resected lymph nodes) and group B for extended (>25 resected lymph nodes) lymph nodes resection. A total of 418 patients were analysed: tumour stage at diagnosis was pT2–3 pN1–3 M0 in 339 patients and pT3 N0 M0 in 79 patients. Median age at diagnosis was 68 years (range 30–92 years). A total of 306 patients (73.2%) were in group A and 112 (26.8%) in group B. The median survival time (OS) for patients in groups A and B was 58.8 and 84.8 months, respectively (P=0.0371); median DFS was 28.8 months in group A and 59.9 months in group B (P=0.0027). At multivariate analysis, extension within the gastric wall, nodal involvement and the number of resected lymph nodes appeared to affect both OS and DFS. An inadequate lymph nodes resection can affect survival and result in a higher incidence of local relapse, making the latter group of patients optimal candidates for adjuvant chemoradiation.

Abstract
BACKGROUND Polymorphisms in the interleukin 1beta gene (IL-1B-31T/C and IL-1B-511C/T single nucleotide changes) and in the interleukin 1 receptor anatagonist gene (IL-1RN2 variable number of tandem repeats) have been studied with respect to gastric cancer susceptibility. Available data support an aetiologic role of these genetic variants in the presence of concomitant Helicobacter pylori infection. Their contribution without H. pylori infection is still an open field of investigation. MATERIALS AND METHODS IL-1B and IL-1RN polymorphisms were investigated in 138 H. pylori-negative Italian patients with sporadic gastric cancer and 100 H. pylori-negative controls. Unconditional regression with odd ratios (OR) and 95% confidence intervals (CI), haplotype and linkage disequilibrium analyses were used to investigate the association of the polymorphisms with disease. RESULTS In all gastric cancer cases, carriers of the homozygous IL-1B-511T/T genotype showed a significant risk for the development of the disease (OR 3.2 with 95% CI 1.27-8.05). In cases with intestinal-type gastric cancer, however, both IL-1B-511T and IL-1RN2 alleles were associated with disease. In this subgroup, the odds ratio for carriers of both IL-1B-511T and IL-1RN2 was 6.49 (95% CI 2.07-20.4). Haplotype analysis supported the aetiologic contribution of these alleles in gastric cancer of the intestinal histotype. CONCLUSIONS In conclusion, IL-1B-511T and IL-1RN2 may contribute to intestinal gastric cancer risk in the absence of concomitant H. pylori infection. In this setting, future epidemiologic studies should consider dietary habits and exposure to carcinogens interacting with pro-inflammatory host genotypes.

Abstract
BACKGROUND The doxorubicin-docetaxel combination is active in breast cancer; the aim of the present study was to evaluate the complete response rate and safety profile of the doxorubicin and docetaxel regimen as first-line chemotherapy in metastatic breast cancer patients. PATIENTS AND METHODS Forty-three patients entered the study. Treatment plan was: doxorubicin (50 mg/m2, i.v. bolus) followed 1 hour later by docetaxel (75 mg/m2 i.v. infusion over 1 hour), q 3 weeks, for up to six courses. The patients achieving a response or a stabilisation of disease after 6 courses were allowed to intensify the treatment with docetaxel (100 mg/m2, q 3 weeks) for up to 2 courses. G-CSF (or GM-CSF) was administered if clinically indicated. RESULTS Patients' median age was 57years (range 32-75) and 72% of them had visceral disease. A total of 217 doxorubicin-docetaxel courses were delivered, with 70% of patients receiving all the 6 planned cycles. Among the 40 patients assessable for response (WHO criteria), 7 (16%) achieved a complete remission and 22 (51%) a partial remission, for an overall response rate (intent-to-treat) of 67% (95% C.I. =53% to 81%). In 19 patients, the treatment was intensified with two more single-agent docetaxel cycles, without ameliorating the response. Twenty-seven patients with oestrogen receptor-positive received hormonal therapy as 'maintenance' after completing chemotherapy treatment. NCIC G3-G4 neutropenia was recorded in 58% of patients, with G/GM-CSF used in 23 (53%) patients and 91 (38%) cycles. No patients experienced severe cardiac or neurological toxicity. No toxic death occurred. With a median follow-up of 41 months among alive patients, we observed in responder patients an overall median time to progression and survival of 18 and 33 months respectively, with ten long-survivors still alive. CONCLUSION This study confirmed the combination doxorubicin-docetaxel as a very active regimen for metastatic breast cancer. Remarkably long survival times were observed not only in complete responders, but also in those patients who responded partially. This might be equally attributed to first-line treatment and sequential maintenance hormonal therapy.

Abstract
Isolated pancreatic metastatic melanoma is a rare occurrence. Even more rare is the surgical treatment of this lesion. However, considering the lack of effective systemic treatment and the decreasing morbidity and mortality rates of pancreatic resections in specialized centers, selected patients, especially if symptomatic, may be considered for surgical resection to achieve good palliation or improve survival. We performed a pancreaticoduodenectomy in a patient with a bleeding pancreatic metastasis from cutaneous melanoma excised 10 years before and reviewed the recent literature.

Abstract
BACKGROUND Hypermethylation is studied as a new, relevant mechanism for silencing tumor suppressor genes. It is a potentially reversible epigenetic change and it is the target of novel anticancer compounds with demethylating activity. In this perspective, we investigated E-cadherin gene (CDH1) promoter hypermethylation in gastric carcinomas and its correlation with E-cadherin protein expression. METHODS Consecutive cases of gastric carcinoma with assessable paraffin-embedded tumor blocks and paired normal mucosa were considered eligible for study entry. CDH1 promoter hypermethylation and E-cadherin protein expression were determined by methylation-specific polymerase chain reaction and immunohistochemistry, respectively. RESULTS CDH1 promoter hypermethylation was found in 20 out of 70 gastric carcinomas and the epigenetic change occurred in the early, as well as in the locally advanced disease. In five cases, hypermethylation was also detected in the normal mucosa. Eighteen out of 20 hypermethylated tumors were of the diffuse histotype (P=0.0001). Of 24 tumors with reduced or negative E-cadherin expression, 19 were hypermethylated and 5 were unmethylated (P=0.0001). CONCLUSIONS CDH1 promoter hypermethylation frequently occurs in gastric carcinomas of the diffuse histotype and it is significantly associated with downregulated E-cadherin expression. The knowledge on the hypermethylation status of tumor suppressor genes may be relevant to the development of demethylating drugs and novel chemopreventive strategies in solid tumors.

Abstract
The aim of the present study was to evaluate the role of a weekly preoperative chemotherapy in locally advanced, unresectable gastric cancer. In all, 82 patients with an Eastern Oncology Cooperative Group PS <or=2 and normal cardiac function were enrolled onto the study. Surgical unresectability was confirmed in 52 patients (63%) at laparotomy, and in 30 (27%) cases by CT scan of the abdomen and endoscopic ultrasonography. Chemotherapy treatment was: cisplatin 40 mg x m(-2); 5-fluorouracil 500 mg x m(-2); epidoxorubicin 35 mg x m(-2); 6S-leucovorin 250 mg x m(-2) and glutathione 1.5 g x m(-2) (PELF). One cycle consisted of 8 weekly treatments. Response to chemotherapy was observed in 40 of 82 patients (49%): six (7%) complete and 34 (41%) partial responses, and in four (5%) cases a complete pathological response was confirmed. Of the 40 responding patients, 37 (45%) had potentially curative surgery. Grade 3/4 leucopenia and thrombocytopenia occurred in three and two patients. At a median follow-up of 48 months, 25 of the 37 resected patients (68%) were alive and 24 (65%) were disease free. The median and 4-year survival for the whole group was 17 months and 31%, respectively. The median survival was 12 months for inoperable patients and it was not reached in resected patients.

Abstract
Among chromosome defects in colon cancer, deletions in 1p, 17p, and 18q have been reported as frequent events. To verify this, we investigated 1p, 17p, and 18q aneusomy in 60 colorectal cancers and their surrounding mucosa by means of fluorescence in situ hybridization (FISH). We also evaluated ERBB2 gene (alias HER-2/neu) amplification in a subset of tumors. The genetic picture in tumors was correlated with chromosomal alterations in normal colonic mucosae, as well with clinicopathologic variables. A population of cells in morphologically normal epithelium possesses genetic aberrations common to those in colon cancer, although in different percentages. No significant difference emerged in terms of fraction of nuclei with 17p monosomy between primary tumors and distal mucosal samples. Of tumor samples aneusomic for the three chromosomes, 58.3% also showed aneusomy in related normal colonic mucosa. In neoplastic samples, significant correlation existed between 1p aneusomy and mucosal component (P<0.007), between 17p aneusomy and increased depth of invasion (T3-T4) (P<0.05), and between 18q aneusomy and tumor site (P<0.03). None of the evaluated samples, neoplastic or normal, showed ERBB2 gene amplification.

Abstract
Loss of function of the E-cadherin gene (CDH1) has been linked with diffuse gastric cancer susceptibility, and germline inactivating mutations in CDH1 characterise the hereditary diffuse gastric cancer (HDGC) syndrome. Hypermethylation in the CDH1 promoter region is a frequent phenomenon in poorly differentiated, diffuse gastric carcinomas and it was identified as the main mechanism for the inactivation of the remaining wild-type allele in HDGC cases. Specific criteria are used to identify patients with suspected HDGC and who should be investigated for CDH1 germline mutations. Accurate screening is mandatory for unaffected carriers of CDH1 mutations and selected high-risk individuals could be considered for prophylactic gastrectomy. Also, germline CDH1 mutations may predispose to lobular breast carcinoma and prostate cancer. Germline CDH1 mutations are not always detectable in patients who meet the HDGC criteria and the aetiological role of this gene is still under investigation. Families without recognised inactivating CDH1 mutations may have undisclosed CDH1 mutations or mutations in its regulatory sequences or germline mutations in unidentified genes that also contribute to the disease. In recent years, several germline missense CDH1 mutations have been identified, some of which showed a marked negative influence on E-cadherin function in experimental models. CDH1 promoter hypermethylation seems a key event in the carcinogenetic process of poorly differentiated, diffuse gastric cancer and it deserves further investigation as a new target for anticancer therapies with demethylating agents.

Abstract
The incidence of gastric cancer (GC) increases significantly after the fifth decade and palliative chemotherapy is the ultimate treatment in the majority of patients. We investigated safety and efficacy of a weekly regimen with cisplatin, fluorouracil and leucovorin as first-line chemotherapy for elderly patients with advanced GC. Chemotherapy-naive patients older than 65 years were considered eligible for study entry. Frail elderly patients were identified and excluded according to the following criteria: age >85 years, dependence in one or more activities of daily living (activities of daily living and instrumental activities of daily living scales), three or more comorbid conditions, one or more geriatric syndromes. Chemotherapy consisted of 1-day per week administration of intravenous cisplatin 35 mg m(-2), 6S-stereoisomer leucovorin 250 mg m(-2) and fluorouracil 500 mg m(-2) (PLF). Patients were re-evaluated after eight weekly cycles and six additional weekly administrations were planned for patients without disease progression. A 5-day subcutaneous filgrastim (5 mug Kg(-1) day(-1), days +1-+5) was used after the first treatment delay for neutropenia and maintained thereafter. In the whole group, the best intention-to-treat overall response rate was 43% (95% CI: 30-56%). The time to disease progression and the median survival time were 5.3 and 8.6 months, respectively. Fatigue was the commonest nonhaematologic toxicity (71% of the patients). Filgrastim was used in 30 patients who showed grade II (20 patients) or grade III (10 patients) neutropenia. Neither grade IV toxicity nor toxic deaths were observed. The weekly PLF regimen resulted safe and effective in elderly patients with advanced GC. This outpatient regimen is based on old and low-cost drugs and it may represent an alternative to new and more expensive combinations.

Abstract
The benefit of postoperative adjuvant chemotherapy in patients with Dukes' B colorectal cancer is still uncertain and its routine use is not recommended. Prognostic biomarkers may be useful for identifying high-risk patients with resected, node-negative disease, and this stratification may represent an innovative strategy for designing adjuvant chemotherapy trials. Featured prognostic molecular markers can be divided into the following categories: cell proliferation indices (Ki-67, Mib-1, proliferating cell nuclear antigen); oncogenes/tumor suppressor genes [p53, K-ras, Deleted in Colorectal Cancer (DCC), Bcl-2, c-erbB2]; DNA repair (microsatellite instability); markers of angiogenesis (vascular count, vascular endothelial growth factor); markers of invasion/metastasis (plasminogen-related molecules, matrix metalloproteinases); and biochemical markers (thymidylate synthase). Studies that have investigated their prognostic role in Dukes' B colorectal cancer patients are reviewed here. Current data do not provide sufficient evidence for the incorporation of available prognostic biomarkers into clinical practice. However, a biomarker-based approach could be an effective strategy for improving results of postoperative adjuvant treatments in high-risk Dukes' B colorectal cancer patients. Markers of altered DCC function have shown promising prognostic role and sufficient prevalence in retrospective investigations and they deserve further assessment in prospective studies.

Abstract
BACKGROUND This phase II study was initiated to determine the activity and toxicity of a combination of gemcitabine (GEM) and cisplatin (CDDP) in patients with pancreatic cancer. PATIENTS AND METHODS CDDP 35 mg/m(2) was given as a 30-min infusion and GEM 1000 mg/m(2) as a 30-min infusion. Both drugs were administered once weekly for 2 consecutive weeks out of every 3 weeks to chemonaive patients with locally advanced or metastatic pancreatic cancer. RESULTS Forty-five advanced pancreatic cancer patients received this regimen for a total of 180 cycles of chemotherapy. One complete and four partial responses have been observed for an overall response rate of 9% (95% confidence interval 10% to 11%). Twenty-one patients (46%) had stable disease and 19 progressed on therapy. The median time to progression was 3.6 months, with a median survival of 5.6 months. A clinical benefit was obtained in nine of 37 patients (24%). Side-effects were mainly represented by hematological toxicity. Grade 3/4 WHO toxicities included neutropenia (6% of the patients) and thrombocytopenia (11%). The dose of GEM and CDDP was reduced in 14 patients (31%) and treatment was delayed in 10 patients (22%). CONCLUSIONS Our results in terms of response rate, clinical benefit and survival do not support an advantage for the combination of GEM and CDDP given by this schedule.

Abstract
BACKGROUND In gastric juice, high levels of the carcinoembryonic antigen (CEA) and the carbohydrate antigen 19-9 (CA 19-9) have been found to correlate with precancerous lesions and gastric cancer. So far, sampling of gastric juice has required upper endoscopy. In place of this invasive procedure, we investigated a new tool for the quantitation of tumor markers in gastric juice. MATERIALS AND METHODS The study population consisted of healthy controls and consecutive subjects with suspected gastric cancer or dyspepsia/epigastric distress. Patients were asked to swallow a small gelatine capsule (14 mm in length and 5 mm in diameter) containing a pierced plastic cover and surrounding a piece of absorbent paper. The capsule was left in the gastric cavity for 60 min to allow saturation of the absorbent paper with gastric juice. A 45-50 cm length of nylon thread connected to the inner capsule was used to remove the device from the gastric cavity. After processing the absorbent paper for radioimmunoassay, CEA and CA 19-9 levels were correlated to the findings of upper endoscopy and biopsies of gastric mucosa or suspected lesions. RESULTS The endogastric capsule did not cause any side-effects and 62 participants were fully compliant to the procedure. Assessable gastric juice samples were taken from 23 patients with gastric cancer, 15 patients with intestinal metaplasia or dysplasia, 12 patients with gastritis and 12 controls without gastric diseases. In the 12 samples of gastric juice from control patients, mean values of CEA and CA 19-9 were 1.1 +/- 0.9 ng/ml and 16 +/- 7.5 ng/ml, respectively. The mean levels of both markers were found to increase according to the severity of gastric lesions and in patients with cancer, mean CEA and CA 19-9 levels were 513 +/- 627 ng/ml and 545 +/- 510 ng/ml, respectively. Patients with precancerous lesions and cancer showed higher levels of CEA and CA 19-9 than patients with normal findings or gastritis (P <0.001). CONCLUSIONS The endogastric capsule is a simple, non-invasive tool for the measurement of CEA and CA 19-9 levels in gastric juice. These values may discriminate between normal or minor pathologic changes and precancerous lesions or carcinomas. Further investigations are warranted, since this may represent a new method for gastric cancer screening.

Abstract
BACKGROUND Cisplatin/gemcitabine are one of the "standard" chemotherapy schedules in locally advanced and metastatic NSCLC cancer. A number of trials documented that omission of gemcitabine on day 15 and reduction of cisplatin up to 70 mg/mq are equivalent in term of response rates to "classic" administrations on days 1, 8 and 15 with cisplatin 100 mg/mq. The aim of this study was to confirm this evidence and to demonstrate that a further reduction of gemcitabine dose-intensity may be performed with the same efficacy on response. PATIENTS AND METHODS Fifty untreated patients with locally advanced and metastatic NSCLC entered the study: 24 stage IIIB and 26 stage IV. The median age was 65 years (range 32-76); 44 males and 6 females Genicitabine was administered 1000 mg/mq weekly on days 1 and 8 followed by a 2-week rest and cisplatin 80 mg/mq on day 2 of each 28-day-cycle. RESULTS Forty-five patients were evaluable for response and all for toxicity. The overall response rates were 35.5% with 16 partial responses (95% Confidence Interval: 32%-61%). Most of the objective responses were seen in IIIB patients (56% of the stage IIIB and 44% of the stage IV patients responded). According to the intent-to-treat-principle, the response rates were 32% (16 out of 50 patients). The median dose-intensity of gemcitabine and cisplatin was respectively 477.6 mg/mq/week (481.4 for responders) and 19.5 mg/mq/week (19.9 mg/mq for responders). The median response duration was 5 months (range 1-18) and the median time to progression was 5 months (1-21); median survival was 9 months (range 2-31). The main toxicity was haematological: thrombocytopenia grade IV in 5 patients (10%) and grade III in 11 patients (22%); neutropenia grade III-IV in 4 patients (8%); grade III anemia in 3 (6%). Asthenia was the most significant non-haematological toxicity and was observed in 19 patients (38%). CONCLUSION This trial confirmed the efficacy of a schedule with 2 administrations of gemcitabine (on days 1, 8) and a cisplatin dose on day 2 lower than 100 mg/mq. Moreover, the same efficacy was obtained with a median-dose intensity of cisplatin and gemcitabine lower than planned in a 21-day-schedule. For safety and low toxicity, we think that this schedule provides another chance to treat patients with non-small cell lung cancer, especially the elderly or patients with coexistent medical illnesses.

Abstract
BACKGROUND Anthracyclines combined with paclitaxel are one of the most active schedules in patients with advanced breast cancer: response rates range from 40 to 80%, considering all metastatic sites (visceral and soft tissues). We performed a non-randomized phase II trial with anthracyclines/paclitaxel combination to evaluate response and toxicity only in patients with visceral metastases. METHODS Twenty-seven patients (median age 50 years; range 30-72) with visceral metastases of breast cancer were enrolled in this study. Overall, 11 patients had lung metastases (41%), 10 liver (37%), 4 liver-lung metastases (15%) and 2 peritoneal carcinosis (7%). 7 patients had received adjuvant anthracycline-based chemotherapy (26%) and 10 patients adjuvant CMF combination chemotherapy (37%); 10 patients (37%) received hormonal therapy for advanced disease. Treatment schedules were: group A) 17 patients, Adriamicyn 50 mg/m2 on day 1 i.v. bolus and Paclitaxel 175 mg/m2 on day 2 i.v. 3 hours infusion, every 3 weeks; group B) 10 patients, epirubicin 90 mg/m2 on day 1 i.v. bolus and paclitaxel 200 mg/m2 on day 2 i.v., 3 hours infusion, every 3 weeks. The number of cycles administered was 141 with a median of 5 (range 3-9). RESULTS All patients were evaluable for response and toxicity. The objective response rate was 59% - 16 patients - (15% complete and 44% partial remission), 95% C.I. 40.7-77%; 10/17 in group A and 7/10 in group B. Stable disease 30% (8 patients) and progressive disease 11% (3 patients). The median duration of response was 5 months (range 1-16); median time to progression 13 months (range 3-18) and median survival 17 months (range 4-24). The main toxicity was neutropenia, occurred in 16 patients (59%; grade IV in 7 patients, of whom 2 febrile neutropenia, and grade III in 9 patients); grade III gastrointestinal toxicity in 2 patients; grade III neurological toxicity in 1 patient; grade III stomatitis in 2 patients. No congestive hearth failure or treatment death related was observed. CONCLUSIONS These schedules of anthracyclines and paclitaxel confirmed their efficacy in metastatic breast cancer even in patients with visceral disease. Neutropenia was the main toxicity; grade IV neutropenia was more frequently observed in epirubicin/paclitaxel arm.
