Unresectable mcrc treatment in 2015 Median expected OS: about 30 months Most of the patients will receive several lines of treatment From 100 in 1st line 60-70 will receive a 2 nd line 30-40 will receive a 3rd Line 15-20% will receive 4+ lines

Groups according to clinical presentation ESMO Consensus Conference 2011 Schmoll H J et al. Ann Oncol 2012;23:2479 Groups Clinical Criteria Group 0 Group 1 Group 2 Upfront resectable metastasis, Goal: cure, reduced relapse rate Potentially resectable metastasis Goal: Objective Response, tumor shrinkage. Multiple metastasis, rapid progression, associated symptoms even in patients without major co-morbidities Goal: Disease control, symptom improvement. Group 3 Multiple metastasis or organ involved, definitely never resectable, Mild symptoms associated, co-morbidities Goal: Disease control, increased survival with preserved quality of life, regimen with mild toxicity profile prefered..

ESMO consensus patients groups Additional predictive biomarkers should be incorporated in treatment decision Ras phenotype allows to select for anti-egfr therapy Braf phenotype for chemotherapy intensification?
ESMO Group 2 mcrc Need for an active regimen for an agressive tumor to stop tumor growth Doublets or Triplets chemo-regimen are preferred To be selected according to tolerance profile/pre-existing conditions Targeted agents may be used in combination with chemotherapy for improved efficacy Decision should be based on RAS phenotype and contra-indications In some cases, patient file should be reviewed in a MDT to discuss possible resection.

ESMO Group 3 mcrc Multiple strategies are possible Several lines will be used The important points are: To try to use all available agents Drug re-introduction may apply To improve survival and preserve quality of life Stop and Go strategies are convenient and may allow longer treatment overall
ESMO Group 3 mcrc Targeted agents + Chemotherapy Bevacizumab is active in combination with chemotherapy Survival benefit is not constantly seen but PFS is Risk factors should be considered If used, should be preferred in early lines No activity as single agent To be discussed if maintenance is used
ESMO Group 3 mcrc Anti-EGFR Monoclonal Antibodies are generally used at a later line of treatment in this patients population Patients should be selected according to K and N RAS wt No sequential trials in this group of patients are available Upfront use of anti EGFR MoAb has been reported in small trial with high efficacy Most frequently used in 3rd or 4th line
State of Art for treatment strategy in mcrc ESMO consensus guidelines as a reference in clinical practice Each individual patient should be referred to 1 of the 4 groups Treatment goal will be stated upfront Treatment options will be identified for discussion
Metastatic Colorectal cancer Basic strategy and groups (RASwt/mut, BRAF mut) Based on present molecular profile and treatment availability mcrc should be split according to: Mutational status of RAS and Braf Metastatic spread Single organ (LLD) potentially resectable Multiple organs never resectable Treatment strategy should be offered accordingly After MultiDisciplinary Team discussion Patients characteristics and desire Taking into consideration the Goal of treatment, the possibility of several lines and also Quality of Life.
Modification possibly to be added after the 2014 consensus conference
Treatment of metastatic disease It is clear that treatment stratification according to ESMO Groups 0, 1, 2 and 3 is no longer representative of what occurs in everyday clinical practice, there can be no clear distinction made between group 1 and 2 patients or between group 2 and 3 patients. Increasingly often patient desire in terms of treatment goal is the main driver of treatment decisions.

Treatment drivers for first-line treatment Tumour characteristics Clinical presentation: Tumour burden Tumour localisation Patient characteristics Age Treatment characteristics Toxicity profile Tumour biology Performance status Flexibility RAS mutation status Organ function Socio-economic factors BRAF mutation status Comorbidities Quality of life, patient expectation and preference

Review of the ESMO Consensus Conference on metastatic colorectal cancer CONCLUSION Metastatic colorectal cancer is a fast-moving field New drugs regularly registered (Regorafenib, TAS-102) Changing label (anti-egfr MoAbs restricted to RASwt) New technologies outside of medical oncology (Sirflox) More than ever a multidiscplinary approach is needed Guidelines need regular updates Consensus is not easy to fine ORR, Progression-free and Overall survival are improving
