Cancer Trivia The word cancer is related to the Greek word crab because its finger-like projections were similar to the shape of the crab In 2010, the economic cost of the disease worldwide was estimated at $1.16 trillion. One in eight deaths in the world are due to cancer. Cancer is the leading cause of death in developed countries. WHO predicts new cancer cases of 14 million in 2012 to 22 million in 2030 and cancer deaths from 8.2 million a year to 13 million annually. There are 28 million cancer survivors worldwide. Men who have never married are up to 35% more likely to die from cancer than those who are married. 4

Oncology Study How are the oncology studies different from other studies? –Tumor measurements and their response to drug –Toxicity (Lab and AE) –Time to Event Analysis What tumor studies and response guidelines? –Solid Tumor : RECIST 1.1 –Lymphoma : Cheson 2007 –Leukemia : IWCLL
What is Lymphoma Cancer that starts in lymph nodes Type of Lymphoma –Hodgkin lymphoma (HL) : lymphoma in the presence of a specific type of abnormal cell called a Reed-Sternberg cell –Non-Hodgkin lymphoma (NHL) : lymphoma not in the presence of a specific type of abnormal cell called a Reed-Sternberg cell Guidelines for response : Cheson
Cheson 2007 History –IWG (International Working Group) 1999 and Cheson 2007 Lesions (tumors) –Type : Enlarged Lymph Nodes (long axis > 15 mm or its greatest perpendicular axis > 10 mm by CT scan) Nodal Masses Extra Nodal Masses (> 10 mm ) 8
Lymphatic System 9 A Nodal Mass is the conglomerate of several enlarged nodes touching one another which are not distinguished from individual nodes any more.
Extra Nodal Site 10 Extra nodal – a lymphoma that is detected outside of lymphatic system.
Cheson 2007 Two-dimensional measurement - product of longest diameter and its greatest perpendicular axis (e.g., 40 mm * 15 mm = 600 mm^2) 11
What is to measure in Lymphoma according to Cheson 2007 Tumor measurements in CT / MRI –Lymph Node, Nodal Masses and Extra Nodal Masses PET scan on lesions (to distinguish viable tumor from fibrosis) Bone Marrow Assessment Spleen and Liver Enlargement Assessment 12
Target Lesions according to Cheson 2007 Normally 6 lesions –lymph nodes or nodal masses –Two perpendicular diameters should be clearly measurable Quantitative measurements –Longest diameter and its greatest transverse perpendicular diameter –Products of the diameters –Sum of the products of the diameters (SPD) up to 6 target lesions 13
Non-Target Lesions according to Cheson 2007 All other lesions beside target lesions Extra nodal (i.e., Liver, Spleen) Quantitative measurements –Longest diameter and its greatest transverse perpendicular diameter –Products of the diameters Qualitative measurements – present, absent, increased or decreased. 14
New Lesions according to Cheson 2007 Any lesions that are newly found at post- baseline Either quantitative or qualitative measurements 15
Lesions at baseline 16 Lesions Measurable Lymph Node or Nodal Masses Non-Measurable or Extra Nodal Masses Targets Non-Targets
Response Criteria Complete Response(CR) : Disappearance of all evidence of disease Partial Response(PR) : Regression of measurable disease and no new sites Progressive Diseases (PD) : Any new lesions or any increase by 50% from nadir in SPD Stable Disease (SD) : Fail to CR/PR or PD Not Evaluable (NE) 17
Complete Response (CR) Nodal Masses Typically FDG-avid lymphoma - if PET is positive in screening, PET is negative for all lesions. Variably FDG-avid lymphoma - all the lymph nodes/nodal masses regress to normal size (<= 15 mm in their greatest transverse diameter or < 10 mm in short axis if their greatest transverse diameter is between 10 and 15) Spleen and Liver – Not palpable, nodules disappeared Bone Marrow – Infiltrate cleared; if indeterminate by morphology, immunohistochemistry should be negative 18
Partial Response (PR) Nodal Masses A 50% decrease in the sum of the product of diameters (SPD) of six target lesions No increase in any lesions Typically FDG-avid lymphoma - if PET is positive in screening, PET is positive at least one lesion. Variably FDG-avid lymphoma - all the lymph nodes/nodal masses regress. Spleen and Liver – Not palpable, nodules regressed by 50 % in SPD. Bone Marrow – Irrelevant 19
Progressive Disease (PD) Nodal Masses Any new lesions (more than 15 mm in any axis) An increase by 50% in SPD from nadir of any involved lesions An increase by 50% in the longest diameter from nadir of any involved lesions Positive PET. Spleen and Liver – nodules increase by 50 % in SPD. Bone Marrow – New or recurrent involvement 20
CDISC Domains or Datasets for Lymphoma Studies SDTM –TU : Tumor Identification –TR : Tumor Results –RS : Response –LB / FA : Bone Marrow –PE : Liver and Spleen Palpable assessment ADaM –-TTE : Time to Event Analysis Datasets 21
Efficacy Evaluation in Lymphoma Primary –Overall Survival : Death as event. –Progression-free survival : Disease Progression or death as a event. preferred end point in Lymphoma studies. Secondary –Event-free survival –Overall Response Rate : Phase II trials of novel new agents –Time to Progression –Disease Free Survival 22
Example Randomized and open label Phase II Study Lymphoma following Cheson cycles 3 target and 2 non-target lesions at screening Primary Efficacy – Overall Survival and Progression Free Survival 23
