Introduction

Colorectal Cancer, traditionally thought to be a disease mostly affecting older, but now is revealing a worrisome trend: a rise in cases among younger people. This alarming increase in the incidence of childhood cancer has been brought to light by a recent study. Improving early detection and treatment outcomes for young patients requires understanding this trend and appropriate action.

Understanding Colorectal Cancer

Colorectal cancer is a type of cancer that starts developing in the colon and rectum (part of the large intestine), Due to the disease's rarity and distinct symptom presentation, colorectal cancer in children can pose different obstacles than it does in adults. As a result, diagnosis is frequently made later in life.

The large intestine, which includes the colon and rectum, is an essential component of the digestive system because it stores waste before it leaves the body and absorbs nutrients and water. 

Structure And Functions Of Colon And Rectum

The longest segment of the large intestine is called the colon. This long, tube-like organ drains water from food after it has been digested. The colon is separated further into: 

The small intestine empties into the ascending colon, which is the first segment of the large intestine. It starts on the lower right side of the abdominal cavity and ascends to the transverse colon. Its length is 20 centimeters. 

The descending colon, which removes waste down the left side of the belly, is reached by the transverse colon, which runs across the top of the abdomen from right to left. At over 45 centimeters in length, it is the largest and most flexible portion of the colon. 

On the left side of the abdominal region, the descending colon is located after the transverse colon. This measures roughly 30 centimeters in length. 

The last portion of the colon to remove waste is the sigmoid colon, which extends a few more inches down to the rectum. It is forty centimeters in length. The rectum and sigmoid colon in cross-section reveal the anus, which is the exit point for waste from the body.

While the descending colon and sigmoid colon are referred to as the distal colon, the ascending colon, and transverse colon together are called the proximal colon. 

The lowest, roughly 15 cm-long segment of the large intestine is called the rectum. It links the anal canal to the sigmoid colon. The waste is held in the colon until the anus passes it out. 

Prevalence of Colorectal Cancer

According to the World Health Organization (WHO), approximately 10% of all cancer cases globally are colorectal cancer cases, making it the second most frequent cancer worldwide and the second biggest cause of cancer-related deaths.

Every year, over a million people worldwide are diagnosed with colorectal cancer, which leads to approximately 715,000 fatalities as of 2010, an increase from 490,000 in 1990.

Developed nations experience it more frequently than emerging ones. The incidence varies 10-fold worldwide, with South-Central Asia and Africa having the lowest rates and Australia, New Zealand, Europe, and the US having the greatest rates.

There have been significant increases in pediatric colorectal cancer cases between 1999 and 2020, according to a recent review of data from the Centers for Disease Control and Prevention. According to research, over that time, the rate of colorectal cancer increased by 500% in children ages 10 to 14, 333% in teenagers ages 15 to 19, and 185% in young adults ages 20 to 24.

Compared to 0.1 per 100,000 children in 1999, only 10 to 14-year-olds received a colorectal cancer diagnosis in 2020. In young adults, the incidence increased from 0.7 to 2 cases per 100,000, and in teenagers, it increased from 0.3 to 1.3 cases per 100,000.

Possible Causes and Risk Factors of Colorectal Cancer

The exact causes of this rise are still being investigated. Still, a number of risk factors have been determined:

Genetic Factors

• A significant risk factor is a family history of colorectal cancer or other cancers. Genetic mutations, such as those associated with Lynch syndrome or familial adenomatous polyposis (FAP), can increase susceptibility.
• Children with inherited conditions like Peutz-Jeghers syndrome or juvenile polyposis syndrome are at a higher risk.

Environmental Factors

• Prolonged exposure to environmental toxins and pollutants may contribute to cancer development.
• Previous radiation therapy for other conditions can increase the risk of developing secondary cancers, including colorectal cancer.

Lifestyle Influences

Several lifestyle factors are also associated with an increased risk of colorectal cancer:

Diet:

Diets high in processed meats and low in fruits, vegetables, and whole grains are linked to higher colorectal cancer risk. High consumption of red meat has also been associated with increased risk due to carcinogens formed during cooking.

Physical Activity

Inactivity is a recognized risk factor. Doing exercise daily helps maintain a healthy weight and also reduces the risk of developing cancer.

The risk of colorectal cancer is increased in those who are overweight or obese.

Other Factors

Smoking and Alcohol: Use of tobacco and excessive alcohol consumption are recognized risk factors for many cancers, including colorectal cancer.

Study Findings on Specific Risk Factors for Children

The recent study on the rise of colorectal cancer in children also identified several specific risk factors:

1. The study found that children diagnosed with colorectal cancer often had a family history of the disease, suggesting a strong genetic component.
2. Children with diets high in processed foods and low in fiber were more frequently diagnosed with colorectal cancer.
3. Sedentary lifestyles were common among the young patients studied, further highlighting the importance of regular physical activity in prevention.

Symptoms and Warning Signs of Colorectal Cancer

Here are some common symptoms of colorectal cancer in children to be aware of:

1. Abdominal pain can be persistent or recurrent.
2. Changes in bowel Habits such as diarrhea, constipation, or a change in the consistency of stool that lasts more than a few days.
3. Presence of blood in stool (bright red or very dark blood)
4. Unexplained weight loss
5. Fatigue, constant tiredness, or weakness that doesn’t improve with rest.
6. Nausea and vomiting.
7. Signs of anemia, such as paleness or shortness of breath, which can result from internal bleeding.

Importance of Early Detection

Early detection can significantly increase the chances of prompt, and successful treatment. Early-stage colorectal cancer is often more treatable and associated with better survival rates, it also may require less aggressive treatment, reducing the overall impact on the child's health and well-being. Detecting cancer early helps prevent it from spreading to other parts of the body, which can complicate treatment.

When to Seek Medical Advice

Parents and caregivers should be vigilant about any persistent or unusual symptoms in their children. Here’s when to seek medical advice:

1. If a child exhibits any of the symptoms listed above for more than a few days, it’s important to consult a healthcare provider.
2. If there is a family history of colorectal cancer or related genetic conditions, regular screenings and prompt medical advice for any concerning symptoms are essential.
3. If a child is diagnosed with polyps or other growths in the colon or rectum, they should be closely monitored by a healthcare provider.

Diagnosis of Colorectal Cancer

Diagnosing colorectal cancer in children involves several steps. Here are the primary diagnostic procedures used:

Colonoscopies:

• A colonoscopy is a procedure that allows doctors to examine the entire colon and rectum using a long, flexible tube with a camera at the end. It is the most definitive test for diagnosing colorectal cancer, as it allows for direct visualization and biopsy of suspicious areas.

Imaging Tests:

• CT Scans that is used to get detailed cross-sectional images of the abdomen and pelvis to detect tumors and assess their spread.
• MRI Scans are particularly useful for visualizing soft tissues and providing detailed images of the rectum and surrounding areas.
• PET Scans help in detecting cancer spread by highlighting areas of high metabolic activity typical of cancer cells.

Biopsies

• During a colonoscopy, if any abnormal growths or polyps are found, a biopsy is performed. This involves taking a small tissue sample for microscopic examination to determine if it is cancerous.

Treatment Options for Colorectal Cancers

Treatment of colorectal cancer in children requires a tailored approach, often involving a combination of therapies. Here are the main cancer treatment options:

Surgery

• Surgical procedures involve Resection (surgical removal of the tumor and surrounding tissues), and Laparoscopic surgery may be used for less extensive disease, offering quicker recovery times.

Chemotherapy

• Chemotherapy is a process of using drugs to eradicate cancer cells throughout the body. It is frequently used to destroy any cancer cells that may have remained after surgery and lower the chance of recurrence. 

Radiation Therapy

• External Beam Radiation is commonly used for rectal cancer to shrink tumors before surgery or to kill remaining cancer cells post-surgery.
• Internal Radiation or Brachytherapy, which involves placing radioactive material inside the body near the cancer cells, is less commonly used in children.

New Advancements and Research in Treatment

Recent advancements in the treatment of pediatric colorectal cancer are promising and focus on improving outcomes and reducing side effects:

Immunotherapy

• This therapy involves using drugs that help the immune system recognize and attack cancer cells. They have shown success in treating certain types of cancer and are being explored for colorectal cancer.
• 2 Genetic Profiling: Advances in genetic testing allow for treatments to be tailored to the specific genetic mutations present in a child's tumor, improving efficacy and minimizing side effects.

Minimally Invasive Techniques

• New surgical techniques and technologies are making surgeries less invasive, reducing recovery times, and improving the quality of life for young patients.

Clinical Trials

• Ongoing research and clinical trials are crucial for discovering new treatments. Enrolling in clinical trials may grant access to innovative treatments that are not yet generally accessible.

Preventative Measures and Recommendations

Preventing colorectal cancer in children involves adopting healthy lifestyle habits and staying vigilant about potential risks. Here are some effective cancer prevention tips:

• Promote a diet rich in whole grains, fibers, fruits, and vegetables.  Limit intake of processed and red meats can help reduce the risk of colorectal cancer.
• Ensure children engage in regular physical activity, aiming for at least 60 minutes of exercise most days of the week.
• Lessen sedentary habits, such as excessive screen time.
• High-risk individuals, especially those with a family history of colorectal cancer or genetic predispositions, should undergo regular screenings.
• Discuss with a healthcare provider about the appropriate age and frequency of screenings.

Recommendations for Parents

• Maintain a smoke-free environment and discourage tobacco use.
• Teach children about the value of leading a healthy lifestyle.
• Remain aware of the medical history of your family and let your healthcare professional know about it.
