A-Z of Survivorship, Genetics & Healthcare Professional Terms

​​​

Autologous Stem Cell Transplant

An autologous stem cell transplant is a specialized treatment sometimes used for relapsed or high-risk Wilms tumor. The procedure involves collecting a child's own healthy stem cells before intensive chemotherapy is administered. After treatment, the stored stem cells are returned to the body to help restore normal bone marrow function and blood cell production. Although not routinely required for all children with Wilms tumor, autologous stem cell transplantation can be an important treatment option in selected cases of recurrent disease.

​

Beckwith-Wiedemann Syndrome

Beckwith-Wiedemann Syndrome (BWS) is a genetic overgrowth disorder associated with an increased risk of developing Wilms tumor and other childhood cancers. Children with BWS may have distinctive physical features, including an enlarged tongue, increased birth weight, abdominal wall abnormalities, and asymmetrical growth. Because of the elevated cancer risk, many children with Beckwith-Wiedemann Syndrome undergo regular screening with abdominal ultrasounds and other surveillance measures to detect Wilms tumor at the earliest possible stage.

​

Cancer Survivorship

Cancer survivorship refers to the phase of care that begins at diagnosis and continues throughout a person's life after cancer treatment. For Wilms tumor survivors, survivorship focuses on monitoring long-term health, managing treatment-related complications, supporting emotional well-being, and promoting a healthy quality of life. Survivorship programs often include regular medical assessments, educational support, psychological care, and screening for late effects associated with chemotherapy, surgery, radiation therapy, and other treatments.

​

Cardiotoxicity

Cardiotoxicity refers to damage to the heart caused by certain cancer treatments, particularly anthracycline chemotherapy drugs such as doxorubicin. Some Wilms tumor survivors may develop changes in heart function months or years after treatment has ended. Because of this risk, long-term follow-up often includes echocardiograms and other cardiac assessments. Early detection and ongoing monitoring can help manage potential complications and support long-term cardiovascular health.

​

Child Life Specialist

A Child Life Specialist is a healthcare professional who helps children and families cope with the emotional and psychological challenges of cancer diagnosis, treatment, and hospitalization. Through age-appropriate education, therapeutic play, emotional support, and coping strategies, Child Life Specialists help reduce anxiety and improve the overall treatment experience. They are often valuable members of the multidisciplinary pediatric oncology team.

​

Chronic Kidney Disease (CKD)

Chronic Kidney Disease (CKD) is a long-term reduction in kidney function that may occur in some Wilms tumor survivors, particularly those with bilateral disease, genetic syndromes, or significant treatment-related kidney damage. CKD can affect the body's ability to filter waste products and regulate fluid balance. Long-term monitoring of kidney function is therefore an important component of survivorship care, helping to identify and manage complications before they become more serious.

​

Clinical Psychologist

A Clinical Psychologist is a mental health professional who helps children, adolescents, and families cope with the emotional impact of cancer. Children diagnosed with Wilms tumor may experience anxiety, depression, stress, fear of relapse, and challenges related to treatment or survivorship. Clinical psychologists provide counseling, behavioral interventions, coping strategies, and emotional support that can improve overall well-being throughout the cancer journey.

​

Denys-Drash Syndrome

Denys-Drash Syndrome is a rare genetic disorder strongly associated with an increased risk of developing Wilms tumor. The condition is caused by mutations affecting the WT1 gene and may also result in kidney disease and abnormalities of sexual development. Children diagnosed with Denys-Drash Syndrome often require careful cancer surveillance and long-term specialist care because of their elevated risk of kidney tumors and progressive renal complications.

​

Endocrinologist

An Endocrinologist is a physician who specializes in hormones, growth, puberty, fertility, and metabolic health. Some Wilms tumor survivors require endocrinology follow-up because cancer treatment can affect growth, hormone production, reproductive health, and normal development. Endocrinologists play an important role in identifying treatment-related endocrine complications and supporting healthy long-term development in childhood cancer survivors.

​

Event-Free Survival (EFS)

Event-Free Survival (EFS) is a commonly used measure in childhood cancer research that describes the percentage of patients who remain free from relapse, disease progression, secondary cancers, or other major complications after treatment. Event-free survival provides important information about treatment effectiveness and long-term outcomes. In favorable histology Wilms tumor, event-free survival rates have improved significantly because of advances in pediatric oncology care.

​

Fertility Preservation

Fertility preservation refers to medical approaches used to protect a child's future ability to have biological children. While many children treated for Wilms tumor experience normal reproductive development, certain chemotherapy drugs, radiation treatments, and stem cell transplant procedures may increase the risk of infertility. Fertility preservation discussions are increasingly recognized as an important component of comprehensive childhood cancer care and survivorship planning.

​

Frasier Syndrome

Frasier Syndrome is a rare inherited disorder associated with mutations in the WT1 gene. Children with Frasier Syndrome may experience kidney disease, differences in sexual development, and an increased risk of certain tumors. Although less common than some other Wilms tumor-associated syndromes, genetic evaluation and ongoing surveillance remain important for individuals diagnosed with this condition.

​

Genetic Counseling

Genetic counseling is a process that helps families understand inherited cancer risks, genetic syndromes, testing options, and potential implications for future health. Genetic counselors work with families to explain complex genetic information in a clear and understandable manner. Genetic counseling may be recommended when Wilms tumor occurs alongside congenital abnormalities, bilateral disease, a strong family history, or features suggestive of an inherited syndrome.

​

Genetic Testing

Genetic testing involves analyzing DNA to identify genetic mutations associated with Wilms tumor and related syndromes. Testing may help determine whether a child has an inherited predisposition to cancer, guide surveillance recommendations, and provide information relevant to family members. Genetic testing has become an increasingly important tool in personalized medicine and risk assessment within pediatric oncology.

​

Growth Delay

Growth delay refers to slower-than-expected physical growth during childhood and adolescence. Certain cancer treatments, including radiation therapy, intensive chemotherapy, and stem cell transplantation, may affect normal growth and development. Survivorship programs often monitor height, weight, puberty, and hormone levels to ensure that potential growth-related complications are identified and managed appropriately.

​

Hearing Loss

Hearing loss is a potential late effect associated with some chemotherapy drugs used in pediatric cancer treatment. Although hearing complications are less common in standard Wilms tumor therapy than in some other childhood cancers, certain high-risk or relapse treatment regimens may increase this risk. Early detection through hearing assessments can help support communication, education, and long-term quality of life.

​

Hypertension (Long-Term)

Long-term hypertension may persist in some Wilms tumor survivors, particularly those who have undergone nephrectomy or experienced treatment-related kidney damage. High blood pressure can increase the risk of cardiovascular disease and other health complications over time. Routine monitoring and early management are therefore important aspects of long-term survivorship care.

 

Infertility

Infertility refers to reduced or absent reproductive function and can occur as a late effect of certain cancer treatments. Although many Wilms tumor survivors retain normal fertility, intensive chemotherapy, radiation therapy, and stem cell transplantation may increase the risk of reproductive complications. Long-term follow-up and fertility counseling can help survivors understand and manage potential concerns.

​

Kidney Function

Kidney function refers to the kidneys' ability to filter waste products, regulate fluid balance, and maintain overall health. Preserving kidney function is a major priority throughout Wilms tumor treatment and survivorship. Survivors often undergo regular blood tests, urine testing, and blood pressure monitoring to assess renal health and identify complications as early as possible.

​

Late Effects

Late effects are health problems that develop months, years, or even decades after cancer treatment has ended. Wilms tumor survivors may experience late effects involving the kidneys, heart, lungs, fertility, growth, hearing, endocrine system, or emotional well-being. Long-term survivorship care is designed to identify these issues early and provide appropriate interventions that support lifelong health.

​

Nephrologist

A Nephrologist is a physician who specializes in kidney health and kidney disease. Pediatric nephrologists often play an important role in the care of children diagnosed with Wilms tumor, particularly those with bilateral disease, genetic syndromes, chronic kidney disease, or treatment-related renal complications. Ongoing nephrology care may continue long after active cancer treatment has ended.

​

Nutritionist

A Nutritionist or pediatric oncology dietitian helps children maintain adequate nutrition during and after cancer treatment. Good nutrition supports growth, immune function, healing, treatment tolerance, and overall well-being. Nutrition professionals provide guidance on managing appetite changes, weight fluctuations, treatment side effects, and long-term dietary health needs throughout the cancer journey.

​

Overall Survival (OS)

Overall Survival (OS) measures the percentage of patients who remain alive after a defined period following diagnosis or treatment. It is one of the most important indicators used to evaluate treatment effectiveness in childhood cancer research. Improvements in surgery, chemotherapy, radiation therapy, supportive care, and survivorship programs have contributed to excellent overall survival rates for many children with Wilms tumor.

​

Perlman Syndrome

Perlman Syndrome is a rare genetic overgrowth disorder associated with an increased risk of Wilms tumor. Children with Perlman Syndrome may have distinctive physical features, developmental challenges, and an elevated likelihood of developing kidney tumors during early childhood. Regular screening and specialized medical care are often recommended to support early detection and treatment.

​

Physiotherapist

A Physiotherapist helps children maintain or regain strength, mobility, balance, and physical function during and after cancer treatment. Physical rehabilitation can be particularly important following surgery, prolonged hospitalization, or intensive therapy. Physiotherapists work closely with families to develop individualized exercise and recovery programs that support long-term physical health.

 

Secondary Cancer

A secondary cancer is a new cancer that develops as a late effect of previous cancer treatment. Although uncommon, certain chemotherapy drugs and radiation therapy exposures may slightly increase the risk of secondary malignancies later in life. Survivorship programs include long-term monitoring designed to identify potential secondary cancers as early as possible.

​

Simpson-Golabi-Behmel Syndrome

Simpson-Golabi-Behmel Syndrome is a rare genetic condition characterized by overgrowth and an increased risk of certain childhood cancers, including Wilms tumor. Children with this syndrome often undergo regular cancer surveillance programs to support early diagnosis and improve treatment outcomes. Genetic evaluation and specialist follow-up are important components of care.

​

Social Worker

A Social Worker provides emotional, practical, financial, and social support to children and families affected by cancer. Social workers help families navigate healthcare systems, access community resources, manage financial challenges, and address psychosocial concerns. They are valuable members of the pediatric oncology team and contribute significantly to comprehensive family-centered care.

​

Survivorship

Survivorship refers to the ongoing phase of life following cancer treatment. For Wilms tumor survivors, survivorship encompasses long-term medical monitoring, emotional support, educational guidance, healthy lifestyle promotion, and management of treatment-related complications. Modern survivorship programs aim not only to improve survival but also to maximize long-term quality of life and overall well-being.

​

Urologist

A Urologist is a surgeon who specializes in conditions affecting the urinary tract and kidneys. Pediatric urologists may be involved in the diagnosis, surgical management, and long-term follow-up of children with Wilms tumor. Their expertise is particularly important when managing complex kidney conditions, nephron-sparing surgery, urinary complications, or survivorship issues affecting the urinary system.

​

WAGR Syndrome

WAGR Syndrome is a rare genetic condition associated with a significantly increased risk of developing Wilms tumor. The name WAGR stands for Wilms tumor, Aniridia, Genitourinary abnormalities, and intellectual disability. Because of the elevated cancer risk, children with WAGR Syndrome often participate in structured surveillance programs involving regular abdominal ultrasounds and specialist follow-up.

​

WT1 Gene

The WT1 Gene is one of the most important genes associated with kidney development and Wilms tumor formation. Mutations or abnormalities involving WT1 can increase the risk of childhood kidney cancer and are linked to several genetic syndromes, including WAGR Syndrome and Denys-Drash Syndrome. Research into WT1 continues to improve understanding of Wilms tumor biology and genetic risk factors.

​

WT2 Region

The WT2 Region refers to a genetic area located on chromosome 11 that plays an important role in growth regulation and fetal development. Abnormalities affecting this region have been linked to Wilms tumor and conditions such as Beckwith-Wiedemann Syndrome. Understanding the WT2 region helps researchers investigate the genetic mechanisms that contribute to childhood kidney cancer development.​​
