Q

criteria for resection for cure of pancreatic adenocarcinoma

A

Resectable tumors are defined as localized to the pancreas, with no evidence of SMV or portal vein involvement (i.e., no abutment, distortion, thrombus, or encasement) and a preserved fat plane surrounding the SMA and celiac artery branches, including the hepatic artery. Patients with imaging consistent with resectable disease should proceed with operative resection.

only regional lymph nodes are still considered operative management

field of resection, ascites, or vascular involvement beyond the borderline 180 dgr incasement

142
Q

pancreatic adenocarcinoma defines borderline resectable as tumors that exhibit one of the following characteristics:

A

(1) severe unilateral or bilateral SMV-portal impingement; (2) less than 180-degree tumor abutment on the SMA; (3) abutment or encasement of hepatic artery, if reconstructible; and (4) SMV occlusion, if of a short segment, and reconstructible

143
Q

Adjuvant chemo for pancreatic adenocarcinoma

A

144
Q

neoadjuvant chemoradiation pancreatic adenocarcinoma

A

no studies have shown an improvement in overall survival for patients who receive neoadjuvant chemotherapy and radiation.

For individuals with significant SMV–portal vein involvement (>180 degrees or short-segment encasement), or hepatic arterial or SMA abutment (<180 degrees) who have been traditionally considered unresectable, neoadjuvant therapy may play an important role in identifying the subset of patients most likely to derive benefit from aggressive multimodality therapy, including surgical resection with vascular reconstruction.[51] This type of aggressive treatment should be undertaken only by an experienced multidisciplinary team in the setting of a clinical trial

Q

best test for pheochromocytoma

A

For pheochromocytoma, the most sensitive markers are serum metanephrines and normetanephrines, which are the breakdown products of circulating catecholamines. If the serum metanephrines are twice the normal level or higher, the patient has a pheochromocytoma;

Do not make the mistake of ordering serum catecholamines, as their rapid fluctuations render them useless. If the result of the serum metanephrines leaves the diagnosis in doubt, a 24 hour urine collection for metanephrines, catecholamines, and vanillylmandelic acid should be ordered. While the sensitivity of this test remains above 95%, it also has better than 95% specificity.
