RESUMEN

BACKGROUND: Patients with familial adenomatous polyposis (FAP) and severe (stage IV) duodenal polyposis are candidates for pancreaticoduodenectomy, which has high morbidity. Little information is available about the feasibility of therapeutic endoscopy for these patients. OBJECTIVE: To evaluate the long-term efficiency and risks of endoscopic therapy. DESIGN: Retrospective study. SETTING: A 2-referral center long-term cohort study. PATIENTS: Thirty-five FAP patients (15 men, mean age 48 years) presenting with stage IV duodenal polyposis were included. Patients had a mean Spigelman classification score of 9.8 points (range 9-12 points) at their first examination. INTERVENTIONS: Patients underwent a surveillance endoscopy, including lateral and axial viewing with chromoendoscopy while under sedation, along with 7 ± 4.8 therapeutic endoscopic sessions during a follow-up period of 9 ± 4.5 years (range 1-19 years) after their first endoscopy. MAIN OUTCOME MEASUREMENTS: Treatment modalities, adverse events, and efficiency (evolution of the Spigelman score) were reviewed. RESULTS: A total of 245 therapeutic endoscopies were performed and 15 adverse events (6%) occurred. During the follow-up period, Spigelman scores decreased in 95% of patients by 6 ± 2.2 points (P = .002). Modeling analysis showed that the mean Spigelman score decreased by 60% after 150 months. LIMITATIONS: Retrospective study and the duration of the follow-up, even though this is the longest follow-up reported in medical literature. CONCLUSION: Endoscopic treatment of severe duodenal polyposis in patients with FAP produces few adverse events and allows efficient downstaging of the polyposis. Long-term follow-up data did not reveal a high risk of invasive duodenal cancer in these patients.

RESUMEN

PURPOSE: Transrectal ultrasonography is considered the best method to stage rectal cancer, and thus the need for preoperative radiotherapy. This retrospective study was designed to determine the prognostic value of uTN classification on survival of patients treated by preoperative radiotherapy and surgery. METHODS: A total of 218 patients with proven rectal adenocarcinoma were staged by transrectal ultrasonography before treatment. Transrectal ultrasonography reports were reviewed for TN classification, quality of examinations, and downstaging (pT < uT). RESULTS: Transrectal ultrasonography stages were as follows: uT1, n = 2; uT2, n = 61; uT3, n = 145; uT4, n = 10; uN0, n = 94; uN+, n = 124. After radiotherapy, based on operative specimen, lesions were staged as pT0, n = 27; pT1, n = 20; pT2, n = 60; pT3/4, n = 111; pN0, n = 160; pN+, n = 58; pM+, n = 10. Downstaging (measured as a reduction in TN level determined by transrectal ultrasonography and pathology of resected specimen) occurred in 42.6 percent for T and 38.1 percent for N. Five-year overall and disease-free survivals were 71.3 and 62.7 percent, respectively (median follow-up, 62 months). In univariate or multivariate analysis including parameters available before treatment, uT and age but not uN were statistically significant prognosis factor for overall survival. Patients with TN downstaging had significantly better overall survival. In multivariate analysis, including all parameters, only age, gender, pT, and pN+ status predicted poor outcome. CONCLUSIONS: In patients with rectal adenocarcinoma treated by preoperative radiotherapy, uT classification determined by transrectal ultrasonography before radiotherapy, pT and pN classification determined after radiotherapy, and tumor downstaging were predictors of survival contrary to uN. Only pTN classification, age, and gender were independent predictors in multivariate analysis.

RESUMEN

OBJECTIVE: To know whether the therapeutic protocol applied in the case of severe acute ulcerative colitis (UC) associating ciclosporine and azathioprine was also effective in the case of moderate chronic active ulcerative colitis (UC). SUBJECTS AND METHODS: in this retrospective study 10 patients (31-65 years, 6 distal colitis, 1 left colitis, 3 pancolitis) moderately active and corticosteroid-resistant or dependent were included. Patients received ciclosporine intraveinously (4 mg/kg/d) and were evaluated 10 days later. If efficient, ciclosporine was given orally for 3 Months, azathioprine was introduced and steroids were progressively tapered. RESULTS: on inclusion the clinical score, based on the Mayo Clinic score, was of 5.7 +/- 0.5. On Day 10, the score decreased significantly (2.1 +/- 0.7, p<0.001) and the therapeutic effect was sustained at the third Month (1.8 +/- 0.7). With azathioprine, 4 patients were still in remission with a mean follow up of 23.3 +/- 15.5 Months. CONCLUSION: therapeutic scheme proposed in severe acute UC failing to respond to steroids may be helpful in some patients with a chronic active UC. Clinical improvement is rapid and long-term response is maintained in about 1 patient out of 2.
