Focused Clincial Updates 2006

To receive full CME credit, you are required to complete the evaluation form and self-test for each chapter you complete. Upon completion of the evaluation form and test, a certificate with your name and number of credits you have claimed will be generated. You must print your certificate using the print function in your browser.

The objectives listed below are to be used when evaluating the program. After completing this program, each participant should be able to:

  • Identify how state of the art and emerging research will impact management of digestive conditions.
  • Review diagnostic and treatment options for patients with several digestive diseases.

 

Barrett's Esophagus

Select one answer for each question. You may change your answers as many times as you need to until you click the "Submit" button located at the bottom of the test.

1. In comparing biopsies every 1 cm along the length of the Barrett's segment with 2 cm intervals:

The authors found no difference in detection of intramucosal cancer when comparing the two

The 1 cm protocol was superior to the 2 cm protocol in detection of intramucosal cancer

The 2 cm interval was superior to the 1 cm interval in detection of cancer

None are correct

2. With regard to the natural history of high-grade dysplasia:

Prevalent cancers were less likely to have early stage disease compared to surveillance detected cancer

Patients with prevalent cancer were more likely deemed to have death due to cancer than those with incident cancer

The progression to cancer from high grade dysplasia was higher in prevalent high-grade dysplasia than incident high grade dysplasia

All are correct

3. With regard to endoscopy and biopsy after photodynamic therapy for high-grade dysplasia:

Squamous overgrowth did not affect detection of neoplasia in a randomized trial

High definition narrow band imaging was no better than routine white light endoscopy in detection of residual Barrett's epithelium after PDT

Cancer was more likely to be missed in patients with squamous overgrowth following PDT

None are correct

4. With regard to biomarkers in Barrett's therapy:

Barrett's length and loss of P16 locus predicted response to PDT in one study

No biomarkers predicted response to PDT

Overall response to PDT (no dysplasia at three months) was under 50%

None of the above are correct
