CCRAN is grateful to our Expert Steering Committee for bringing their knowledge and expertise to the development of the 2025 Early Age Onset Cancer Symposium.

Dr. Raphael is a Medical Oncologist and the Early Age Onset CRC Cancer Clinic Lead at the Odette Cancer Centre at Sunnybrook Health Sciences Centre. His practice is dedicated to the care of patients with gastrointestinal cancers. He completed his medical degree at Queen’s University and his internal medicine and medical oncology training at the University of Toronto. He then completed an advanced cancer health services research fellowship and a Master’s of Science (Healthcare Quality, Risk and Safety) at Queen’s University. His research focus is on population-based cancer care. His research aims to identify ways to optimize the coordination and delivery of cancer care services, and to describe gaps in care, disparities in access to treatment, uptake of cancer therapies, and real-world toxicity and effectiveness. His research has already influenced practice guidelines globally and led to a new quality metric that is routinely captured by Cancer Care Ontario (“time to initiating adjuvant chemotherapy”). He is also a valued member of CCRAN’s Scientific & Medical Advisory Board.

Dr. Ashamalla obtained his undergraduate Honours degree from the University of Guelph in Biomedical Sciences followed by a Master of Science degree at Queen's University. He then returned to Toronto and completed his medical degree at the University of Toronto. This was followed by a residency in General Surgery also at the University of Toronto. After completing his training in General Surgery, he went on to complete advanced training in Minimally Invasive Surgery. His clinical interest is devoted to Lower Gastrointestinal Surgical Oncology with a clinical focus on the Minimally Invasive approach. He is with the Surgical Oncology team at Sunnybrook Health Sciences Centre in the Odette Cancer Centre with a practice completely devoted to Lower Gastrointestinal Surgical Oncology with focus on the advancement of the Minimally Invasive technique within the field of Surgical Oncology. Dr. Ashamalla also heads up a one-of-a-kind clinic at the Odette Cancer Centre at Sunnybrook Health Sciences Centre – the Young Adult Colorectal Cancer Clinic - dedicated to serving the needs of the under 50 population, as they face the challenges and concerns related to a colorectal cancer diagnosis.

Dr. Tanya Chawla graduated in medicine from the Imperial college (University of London, UK) and undertook her diagnostic radiology training at Southampton University Hospital NHS trust in the UK. She was a fellow in abdominal Imaging at the Joint department of medical imaging in Toronto. She returned briefly to the UK to take a position as a consultant radiologist in abdominal and oncological imaging at the Portsmouth Hospital NHS trust prior to returning to JDMI. Her clinical and research interests are in all aspects of abdominal imaging but her focus has been on GI and gynecological imaging. Her research projects and presentations have been presented at multiple major national and international society meetings and recognized with awards by societies such as ESGAR and RSNA.
She is currently university divisional head for abdomen at the University of Toronto. She is also vice chair for CPD in the Department of Medical Imaging.
Her passion for education is reflected by her leadership role at the Advanced Imaging Education Centre (AIEC) and she is past chair of the ASM scientific planning committee for the Canadian Association of Radiologists (CAR). She was awarded the fellowship for the CAR (2023). She is the past president for the Canadian Society for Abdominal Radiology (CSAR) and represents radiology on the Gynecological cancer advisory committee at Ontario Health (formerly Cancer Care Ontario).

She held Career Scientist awards from CIHR and NCIC for her psychosocial oncology research, completing studies of psychotherapeutic treatments to support adjustment to being diagnosed with cancer or receiving genetic risk information in breast, colorectal or pancreatic cancer. Other areas of research include studies addressing body image among cancer survivors or the management of grief and loss. Dr. Esplen gives numerous workshops and keynotes and has received several awards, including the lifetime achievement award from Canadian Association Psychosocial Oncology and the Bernard Fox Memorial Award from International Psycho-oncology Society.

Steve Slack is a married father of 2 boys aged 18 and 20 years old. Back in 2019, at the age of 46, he went to his family doctor for the first time to complain about symptoms he was experiencing. Unfortunately, he was not referred for a colonoscopy at that time and was misdiagnosed as having food sensitivities. Two years later, with the symptoms worsening, he went back to his family doctor and was referred for a colonoscopy, which uncovered a large tumour in the sigmoid section of his colon. A few days later, an MRI scan confirmed 23 metastatic lesions on his liver as well. He was told that the cancer in his liver was inoperable and incurable. He underwent emergency colon resection surgery, and after recovering from that he began systemic therapy with FOLFIRI and Panitumumab. Six months into that, he had surgery to implant a Hepatic Artery Infusion Pump and then did 6 rounds of HAIP chemo infusions in conjunction with continued systemic therapy. Luckily, the cancer had a great response to the treatments, as the cancer in his liver shrank from 23 metastases to just 1. This set him up to be eligible for a liver transplant, as a potentially curative treatment for his “incurable” cancer. He started the living donor liver transplant process in April 2023. On November 27, 2023, he received a full liver transplant, and in doing so, hopefully removed all cancer from his body for good. Regular scans post-transplant have continued to confirm that he remains in No Evidence of Disease status.
