Effect of a multidisciplinary cancer conference for thoracic malignancies on patient care management.

112 Background: Treatment of thoracic cancers frequently involve multiple subspecialties thus treatment decisions are typically best facilitated in multidisciplinary tumor boards (MTB). This approach should facilitate and improve treatment decision making, standardize staging and therapeutic decisions and improve outcomes. In this study we analyze the evolution in staging and treatment decision making associated with presentation at MTB. Methods: Retrospective review of all patients with lung or esophageal cancer presented at our weekly MTB from June 1, 2010 to September 30, 2012. All providers submitting patients to tumor board recorded their current treatment plan prior to presentation. The physician’s plan was then compared to the tumor board’s final recommendation. Changes made were graded according to degree of magnitude as minor, moderate or major change. Minor changes included changes in diagnostic imaging. Moderate changes involved modifications in the type of invasive staging or biopsy procedures. Major changes were defined as changes to final therapeutic plans such as surgery, chemotherapy, or radiation therapy. Results: 435 patients with esophageal or lung cancer were discussed in the MTB. 86 patients having no prior treatment plan available were excluded. In the remaining 347 patients there were 163 patients with esophageal cancer (47%) and 184 patients with lung cancer (53%). In the esophageal cancer patients a change to the physician’s prior treatment plan was recommended in 33 cases (21%). For lung cancer patients a change in the treatment plan was recommended in 50 cases (27%). Overall a recommendation for change in treatment occurred in 83 cases (24 %). Changes were major 13%, moderate 6% and minor 5%. Follow-up in 249 patients confirmed that MTB recommendations were followed in 97% of cases. Conclusions: MTB recommendations frequently differs from the physician’s primary treatment plan. MTB reviews have previously been documented to improve patient’s outcome. The study demonstrates that in one quarter of patients MTB recommendation will be different from the primary treatment plan. Complex cancer patients should be considered for presentation at MTB whenever feasible.
