This was recently noticed in the CORRECT trial, comparing regorafinib – an oral multikinase inhibitor of angiogenic, oncogenic, and stromal kinases – to best supportive care in mCRC patients, who had progressed after all approved standard therapies (7). Noteworthy response rate was only 1%, but despite lack of tumor regression, Inhibitors,research,lifescience,medical disease-control was seen in almost half of patients, and this translated into a significantly prolongation of median PFS

(1.7 to 1.9 months; HR 0.49) and OS (5.0 to 6.4 months; HR 0.77). In the Franck et al. study, PFS was 2.1 months and OS 6.8 months, which are almost identical to the CORRECT study. It can therefore not be excluded that treatment with Inhibitors,research,lifescience,medical lapatinib may cause stabilisation of disease with prolongation of life without objective response according to RECIST in a selected group of patients. There has been great progress in understanding of and treatment of mCRC in recent years. However our knowledge on the mechanisms contributing to disease progression and resistance to therapy are still sparse, and decisions on treatment strategy in later lines are most often based on the profile in the primary tumor. In breast cancer it has been demonstrated that there might be discordance in the molecular Inhibitors,research,lifescience,medical profile of the primary and metastases with potential implications

for therapy (8). It is therefore very important that clinical studies – also in late lines of therapy – are combined with translational studies including re-biopsy of metastases resulting in new important knowledge which are the basis for further personalized Inhibitors,research,lifescience,medical treatment in patients with mCRC.

In the year 2010, the incidence of newly diagnosed RAD001 ic50 pancreatic cancer in USA was 43,140 and deaths attributable to pancreatic cancer were 18,770 (1). Among recently diagnosed pancreatic cancer patients, 65-70% will have advanced disease (stage

III-IV) at initial presentation. Advanced pancreatic cancer has a very poor prognosis, Inhibitors,research,lifescience,medical with a median survival of 2-6 months for stage IV disease and 6-11 months for stage III disease. Idoxuridine Overall, the 5-year survival among these patients is only 5-7% and the majority of patients survive less than 1-2 years. Even among patients who undergo surgery with curative-intent, >90% develops disease progression within 12-18 months. This poor prognosis is attributable to late stage presentation, lack of effective treatments, early recurrence and absence of clinically useful biomarker(s) which can detect pancreatic cancer in its precursor form(s) or earliest stages (2-4). A wide-variety of tumor markers derived from serum, pancreatic tissue, pancreatic juice, saliva and/or stool has been proposed for early diagnosis as well as to predict prognosis in pancreatic cancer patients.
