No consensus has been reached on the best method of esophagojejunal anastomosis leakage management and the rate of failure remains significant. Different options of treatment are available but early detection and multidisciplinary approaches are the keys to obtain successful results irrespective of the employed strategy.

BackgroundPatients with hereditary non-poliposys colorectal cancer (HNPCC) have better prognosis than sporadic colorectal cancer (CRC). Aim of our retrospective study was to compare the overall survival between sporadic CRC and HNPCC patients.MethodsWe analyzed a cohort of 40 (25 males and 15 females) HNPCC cases with a hospital consecutive series of 573 (312 males and 261 females) sporadic CRC observed during the period 1970–1993. In 15 HNPCC patients we performed mutational analysis for microsatellite instability. Survival rates were calculated by Kaplan-Meier method and compared with log rank test.ResultsThe median age at diagnosis of the primary CRC was 46.8 years in the HNPCC series versus 61 years in sporadic CRC group. In HNPCC group 85% had a right cancer location, vs. 57% in the sporadic cancer group. In the sporadic cancer group 61.6% were early-stages cancer (Dukes' A and B) vs. 70% in the HNPCC group (p = ns). The crude 5-years cumulative survival after the primary CRC was 94.2% in HNPCC patients vs. 75.3% in sporadic cancer patients (p < 0.0001).ConclusionOur results show that overall survival of colorectal cancer in patients with HNPCC is better than sporadic CRC patients. The different outcome probably relates to the specific tumorigenesis involving DNA mismatch repair dysfunction.

Galectins are a family of beta-galactoside binding molecules involved in cell--extracellular matrix adhesion processes. Specifically, Galectin-3 (Gal-3), one of the members of this family of molecules plays a role in cell adhesion processes as well as in cell survival or apoptosis. Gal-3 was also hypothesized to represent a useful tool in tumor characterization, for example, in thyroid tumors. We report herein the results obtained by evaluating Gal-3 expression of colon cells from human adenomas and adenocarcinomas with two different methodologies: immunohistochemistry and flow cytometry of living dispersed cells. We found that (1) the expression of Gal-3 was significantly increased on the surface of cells from adenomas with respect to normal mucosa from the same patient; (2) Gal-3 ligand, 90k molecule, was increased in the blood plasma from patients with both adenomatous and adenocarcinomatous lesions; and (3) Gal-3 overexpression was not related with the presence of K-ras mutation. Altogether these results clearly indicate that the evaluation of Gal-3 expression (and of its ligand, 90k) can be of interest in the characterization of nonmalignant and malignant colon cancers.

BackgroundThis retrospective analysis is focused on the efficacy and safety of radioimmunotherapy (RIT) with Zevalin® in nine patients with recurrent follicular lymphoma (FL) who were treated in a consolidation setting after having achieved complete remission or partial remission with FCR.MethodsThe median age was 63 yrs (range 46-77), all patients were relapsed with histologically confirmed CD20-positive (grade 1 or 2) FL, at relapse they received FCR every 28 days: F (25 mg/m2x 3 days), C (1 gr/m2 day 1) and R (375 mg/m2 day 4) for 4 cycles. Who achieved at least a partial remission, with < 25% bone marrow involvement, was treated with 90Yttrium Ibritumomab Tiuxetan 11.1 or 14.8 MBq/Kg up to a maximum dose 1184 MBq, at 3 months after the completion of FCR. The patients underwent a further restaging at 12 weeks after 90Y-RIT with total body CT scan, FDG-PET/CT and bilateral bone marrow biopsy.ResultsNine patients have completed the treatment: FCR followed by 90Y-RIT (6 patients at 14.8 MBq/Kg, 3 patients at 11.1 MBq/Kg). After FCR 7 patients obtained CR and 2 PR; after 90Y-RIT two patients in PR converted to CR 12 weeks later. With median follow up of 34 months (range 13-50) the current analysis has shown that overall survival (OS) is 89% at 2 years, 76% at 3 years and 61% at 4 years. The most common grade 3 or 4 adverse events were hematologic, one patient developed herpes zoster infection after 8 months following valacyclovir discontinuation; another patient developed fungal infection.ConclusionsOur experience indicate feasibility, tolerability and efficacy of FCR regimen followed by 90Y-RIT in patients relapsed with grades 1 and 2 FL with no unexpected toxicities. A longer follow up and a larger number of patients with relapsed grades 1 and 2 FL are required to determine the impact of this regimen on long-term duration of response and PFS.
