Cholelithiasis is considered an extraintestinal manifestation of Crohn's ileitis but has not been associated with ulcerative colitis. To evaluate if an increased risk of cholelithiasis exists in patients with ulcerative colitis, biliary ultrasonography was performed on 159 patients with inflammatory bowel disease, 114 patients with ulcerative colitis, and 45 patients with Crohn's disease. A control population of 2453 residents of the town near the authors' institute was also studied. An echographic survey of gallstones was performed on the control subjects, who participated in the Multicentrica Italiana Colelitiasi (MICOL). Seventeen patients with inflammatory bowel disease had gallstones (10.7 percent), 11 patients with ulcerative colitis had gallstones (9.6 percent), and 6 patients with Crohn's disease had gallstones (13.3 percent). In the control population, diagnosis of cholelithiasis was made in 239 subjects (9.7 percent). An estimate of the relative risk (odds ratio) of gallstones in ulcerative colitis and Crohn's disease and also in 4 subgroups formed on the basis of the extent of disease (total ulcerative colitis, partial ulcerative colitis, Crohn's disease with ileitis, Crohn's disease without ileitis) with respect to the general population was calculated using logistic regression with gallstones, sex, age, and body mass index as independent variables and inflammatory bowel disease as a dependent variable. The author's findings show an increased risk of gallstones in both patients with Crohn's disease (odds ratio = 3.6; 95 percent confidence limits = 1.2 - 10.4; P = 0.02) and patients with ulcerative colitis (odds ratio = 2.5; 95 percent confidence limits = 1.2 - 5.2; P = 0.01). The risk was highest in patients with Crohn's disease involving the distal ileum (odds ratio = 4.5; 95 percent confidence limits = 1.5 - 14.1; P = 0.009) and in patients with total ulcerative colitis extending to the cecum (odds ratio = 3.3; 95 percent confidence limits = 1.3 - 8.6; P = 0.01). These results confirm that there is an increased risk of gallstones in Crohn's ileitis but they show that there also exists an increased risk in patients with total ulcerative colitis.

Continuing cetuximab treatment in combination with chemotherapy is of potential therapeutic efficacy in molecularly selected patients and should be validated in randomized phase III trials.

BackgroundBone metastasis represents an increasing clinical problem in advanced gastric cancer (GC) as disease-related survival improves. In literature, few data on the natural history of bone disease in GC are available.Patients and MethodsData on clinicopathology, skeletal outcomes, skeletal-related events (SREs), and bone-directed therapies for 208 deceased GC patients with evidence of bone metastasis were statistically analyzed.ResultsMedian time to bone metastasis was 8 months (CI 95%, 6.125–9.875 months) considering all included patients. Median number of SREs/patient was one. Less than half of the patients (31%) experienced at least one and only 4 and 2% experienced at least two and three events, respectively. Median times to first and second SRE were 2 and 4 months, respectively. Median survival was 6 months after bone metastasis diagnosis and 3 months after first SRE. Median survival in patients who did not experience SREs was 5 months. Among patients who received zoledronic acid before the first SRE, the median time to appearance of first SRE was significantly prolonged compared to control (7 months vs 4 months for control; P: 0.0005).ConclusionsTo our knowledge, this retrospective analysis is the largest multicenter study to demonstrate that bone metastases from GC are not so rare, are commonly aggressive and result in relatively early onset of SREs in the majority of patients. Indeed, our large study, which included 90 patients treated with ZOL, showed, for the first time in literature, a significant extension of time to first SRE and increase in the median survival time after diagnosis of bone metastasis. Taken together, these data may support the beneficial effects of ZOL in GC patients.

BACKGROUNDIn patients with metastatic colorectal carcinoma (MCC), capecitabine has demonstrated a superior response rate (RR), equivalent disease progression‐free (PFS) and overall survival (OS), and an improved overall tolerability profile compared with bolus 5‐fluorouracil/leucovorin (5‐FU/LV). The FOLFOX4 regimen, combining oxaliplatin with LV and bolus plus infusional 5‐FU (LV5FU2), has been shown to improve RR and PFS versus LV5FU2, and it was more effective and less toxic than irinotecan plus bolus 5‐FU/LV. Capecitabine (an oral fluoropyrimidine) may be an effective, well tolerated, and more convenient alternative to 5‐FU/LV in combination with oxaliplatin, especially in older patients.METHODSElderly (≥ 70 years) patients with MCC were treated with a 3‐weekly regimen of oxaliplatin at an initial dose of 85 mg/m2 intravenously on Day 1 plus capecitabine 1000 mg/m2 orally twice daily from Days 2 to 15 (XELOX regimen). In the absence of Grade ≥ 2 hematologic toxicity, oxaliplatin was increased to 100 mg/m2 in the second cycle, and in the absence of Grade ≥ 2 nonhematologic adverse events during Cycle 2, capecitabine was increased to 1250 mg/m2 twice daily in the third and subsequent cycles. After the first 35 patients (first series), the treatment protocol was amended so that only an oxaliplatin increase to 110 mg/m2 and 130 mg/m2 during Cycles 2 and 3, respectively, was planned in the remaining 41 patients (second series).RESULTSSeventy‐six patients with a median age of 75 years (range, 70–82 years) entered the current study. In the first series, the oxaliplatin dose was increased in 18 (51%) patients, and the capecitabine dose was increased in 4 (11%) patients. In the second series, the oxaliplatin dose was increased to 110 mg/m2 in 26 (63%) patients, and to 130 mg/m2 in 19 (46%) patients. In all, 2 complete and 29 partial responses were observed, for an overall RR of 41% (95% confidence interval [CI], 30–53%). The median PFS was 8.5 months (95% CI, 6.7–10.3 months), and the median OS was 14.4 months (95% CI, 11.9–16.9 months). In a multivariate analysis, the presence of disease symptoms affected both PFS and OS, whereas OS also was independently affected by male gender and disease spread. Age had no independent effect on PFS or OS. Five percent of patients developed Grade ≥ 3 hematologic toxicity during treatment, Grade 3 peripheral neuropathy occurred in 8% of patients, and severe hand‐foot syndrome in 13% of patients.CONCLUSIONSFit elderly patients with MCC showed a good RR to XELOX with only mild toxicity observed in most patients. XELOX, should, therefore be considered as an important therapeutic option for elderly patients with MCC. Cancer 2005. © 2005 American Cancer Society.
