Pros of Concurrent Treatment:

• Enhanced Effectiveness: Research indicates that combining chemotherapy with radiation therapy can enhance the overall effectiveness of treatment. This is particularly true for certain cancers, including brain, head and neck, gastrointestinal, bladder, and lung cancers. When these cancers are located in challenging areas of the body, concurrent treatment can improve the chances of successful outcomes.
• Coordinated Care: At El Portal Comprehensive Cancer Centers (EPCCC), our experienced team of board-certified medical oncologists and radiation oncologists work closely together to ensure that your treatment is well-coordinated. This collaborative approach helps to minimize potential interactions between therapies.

Cons of Concurrent Treatment:

• Increased Side Effects: While concurrent treatment can be more effective against cancer, it can also place added stress on your body. Patients often experience intensified side effects such as nausea, fatigue, pain, and hair loss. These heightened reactions can be challenging and require careful management.
• More Frequent Appointments: Receiving both chemotherapy and radiation at the same time typically involves more appointments in a shorter timeframe. This means additional monitoring, including scans and blood draws, which can add to the overall stress of the treatment process.

Given the potential challenges associated with concurrent treatment, many patients may find that their treatment plan recommends therapies to be administered sequentially rather than simultaneously. A comprehensive approach may include surgery, chemotherapy, radiation therapy, immunotherapy, or targeted therapy—either alone or in combination.

Neoadjuvant Therapy: When chemotherapy or radiation is administered before surgery, the goal is to shrink the tumor or eliminate cancer cells outside the primary tumor site. This is known as neoadjuvant therapy and can enhance the effectiveness of surgical intervention.

Adjuvant Therapy: Conversely, if chemotherapy or radiation is administered after surgery, it serves the purpose of targeting any residual cancer cells that may remain, thus reducing the risk of recurrence. This approach is called adjuvant therapy.

By spacing out treatments, your body has the opportunity to recover between therapies, often resulting in fewer and less severe side effects.

Conclusion

Navigating cancer treatment options can be overwhelming, and each patient’s circumstances are unique. It’s important to discuss your individual situation with your healthcare team to determine the best approach tailored to your needs. Understanding the pros and cons of concurrent treatment, as well as the benefits of sequential therapies, can empower you to make informed decisions about your care. Remember, you are not alone in this journey, and a supportive team is here to help guide you every step of the way.

Most colorectal cancers are detected during routine screenings, which have become more streamlined, making it easier for you to stay on track with your health. It’s essential to know the types of tests available for early detection of colorectal cancer.

1. Colonoscopy: This procedure involves using a long, flexible tube with a camera to examine the entire colon and rectum. It’s the most comprehensive screening method and allows for the removal of polyps during the exam.
2. Flexible Sigmoidoscopy: Similar to a colonoscopy but examines only the rectum and the lower part of the colon. It requires less preparation and can be done in a doctor’s office.
3. Fecal Occult Blood Test (FOBT): This non-invasive test checks for hidden blood in the stool, which can be a sign of cancer or polyps. It usually requires multiple stool samples over several days.
4. Fecal Immunochemical Test (FIT): Another stool test that detects blood in the stool using antibodies. It’s more specific than the FOBT and does not require dietary restrictions.
5. CT Colonography (Virtual Colonoscopy): This imaging test uses X-rays and computer technology to create detailed pictures of the colon. It’s less invasive than a traditional colonoscopy but cannot remove polyps.
6. DNA Stool Test: This test analyzes stool samples for specific DNA markers that may indicate the presence of cancer or pre-cancerous conditions. It can be more comprehensive in its approach.
7. Blood Tests: While not used for routine screening, certain blood tests may help assess liver function or detect tumor markers in some cases.

These tests help identify colorectal cancer or pre-cancerous polyps early when treatment is most effective. It’s important to discuss with a healthcare provider which screening method is best suited for individual risk factors and medical history.

Plainly put: Regular screening can save lives!

During the early stages of colorectal cancer, there are typically no visible signs of its presence, making screenings crucial for identifying pre-cancerous and cancerous areas while they are still small. Early detection often leads to fewer treatment demands and greatly increases success rates.

Although it might feel uncomfortable, please don’t shy away from scheduling your screening, especially if you are over 40. Taking this step with your primary care physician can help you create a personalized colon cancer screening plan that is right for you.

Several screening tests are available, ranging from convenient at-home options to more comprehensive procedures performed at healthcare facilities. Your doctor will work with you to select the best method based on your age and family history.

At-Home Screening Options

These tests allow you to screen in the comfort of your home without extensive preparation, though they may carry risks of false positives.

1. At-Home Testing for Colorectal Cancer: If you are under 50, your physician may recommend at-home testing before scheduling a colonoscopy. This approach lets you complete the test without a day of prior colon preparation. However, it’s essential to note that these tests may overlook some polyps and cancers.
2. Stool DNA Test: Advances in at-home stool testing, such as Cologuard, have made it easier to conduct Fecal Immunochemical Tests (FIT). This simple test checks for blood and genetic changes without requiring extensive dietary changes.
3. Guaiac-based Fecal Occult Blood Test (gFBOT): Another home test prescribed by your doctor, gFBOT identifies hidden blood in the stool. If blood is detected, follow-up with a colonoscopy is typically necessary.

Screening at Healthcare Facilities

Screening procedures conducted in medical facilities are often the most accurate and valuable in colorectal cancer detection, allowing for the immediate removal of any suspicious polyps.

• Standard Colonoscopy: In this procedure, a colonoscope provides detailed images of your colon and allows for tissue removal if abnormalities are found. Proper preparation and sedation are necessary for successful outcomes, and studies show that regular colonoscopies can significantly reduce colorectal cancer mortality rates.
• Virtual Colonoscopy: Utilizing CT imaging to view your colon, this test usually does not require sedation but does involve bowel preparation. If potential issues arise, a standard colonoscopy may follow for confirmation.

When Should You Be Screened for Colorectal Cancer?

The American Cancer Society (ACS) has recently lowered the recommended screening age from 50 to 45 due to rising colorectal cancer rates among younger adults. Contributing factors may include dietary choices, physical inactivity, and obesity.
Recommended screening frequencies vary based on risk levels:

• Average Risk: Adults with no family history of colorectal cancer should undergo screenings every ten years.
• High Risk: Those with a family history, previous inflammatory diseases, or prior radiation exposure to the pelvic area should start screenings earlier and have them more frequently.

Like many cancers, various factors influence your risk of developing colorectal cancer—some of which are controllable and others that are not. While no one can predict with certainty if or when colorectal cancer will arise, educating yourself about these risk factors can empower you to take proactive measures to reduce your likelihood of diagnosis.

By staying informed and proactive, you can play an essential role in your health journey and work towards minimizing your risk of colorectal cancer. At El Portal Comprehensive Cancer Centers, we are here to support you with expertise and compassion every step of the way.

The most critical warning sign of skin cancer is the appearance of a new spot on the skin or changes in an existing spot that seem abnormal. Following the A B C D E guidelines can help you identify the common signs of skin cancer:

• Asymmetry:One half of a mole (or birthmark) does not match the other half.
• Border:Edges are irregular, ragged, notched, or blurred.
• Color:The color is uneven, often featuring different shades of brown or black, along with patches of pink, red, white, or blue.
• Diameter:The spot is larger than 6 millimeters across (about the size of a pencil eraser).
• Evolving:The mole is changing in size, shape, color, or elevation. 

Skin cancer is typically identified first by a healthcare professional during an examination of an unusual area on the skin. However, determining whether it is cancerous requires removal and subsequent testing, known as a biopsy. This is the only reliable method to confirm a skin cancer diagnosis.

You may have your biopsy performed in a dermatologist’s office or as an outpatient procedure in a hospital or clinic, depending on the size and location of the abnormal area. Local anesthesia is usually administered to ensure your comfort.

There are four common types of skin biopsies:

• Punch Biopsy:A sharp, hollow tool is used to remove a circle of tissue from the abnormal area.
• Incisional Biopsy:A scalpel is employed to remove a portion of the growth.
• Excisional Biopsy:The entire growth and some surrounding tissue are removed with a scalpel.
• Shave Biopsy:A thin, sharp blade is used to shave off the abnormal growth.

If there is a possibility of melanoma, dermatologists will generally avoid simply shaving or cauterizing the growth. Instead, an excisional biopsy will be performed, or if the growth is too large, a tissue sample will be collected.

Upon receiving a biopsy confirmation of skin cancer, you will be referred to a specialized oncologist for further evaluation and care. Understanding the extent, or stage, of your cancer is crucial, whether you have melanoma or nonmelanoma skin cancer. Staging involves a meticulous assessment to determine how thick the tumor is and whether it has metastasized to other parts of the body. If the tumor is particularly thick, your doctor may recommend chest x-rays, blood tests, and imaging scans of the liver, bones, and brain.

Knowing the stage of your cancer enables your oncologist to:

• Assess the seriousness of your cancer and your chances for survival
• Formulate the most effective treatment plan for your unique situation
• Identify clinical trials that may present additional treatment options

In some cases, your oncologist may need to examine your lymph nodes to accurately stage the cancer. Surgical procedures may be part of the treatment plan to remove cancerous lymph nodes, which can aid in managing the disease.

Staging Criteria
Staging is based on several key factors:

• The size of the tumor
• How deeply it has penetrated below the surface of the skin
• Whether it has spread to nearby lymph nodes or other organs

Oncologists utilize Roman numerals I through IV to designate the cancer stage. Stage I indicates small tumors that are confined to their original site, while Stage IV signifies advanced cancer that has spread to distant sites in the body.

Nonmelanoma Skin Cancer Staging
The stages of nonmelanoma skin cancer are as follows:

• Stage 0: The cancer is localized to the top layer of skin, classified as carcinoma in situ.
• Stage I: The tumor measures 2 centimeters (approximately three-quarters of an inch) or smaller.
• Stage II: The tumor exceeds 2 centimeters in diameter.
• Stage III: The cancer has spread beyond the skin to underlying tissues such as cartilage, muscle, or bone, or to nearby lymph nodes, but not to distant locations.
• Stage IV: The cancer has metastasized to other areas in the body.

Melanoma Staging
The staging for melanoma specifically is defined as follows:

• Stage 0: Melanoma cells are confined to the outer layer of skin (epidermis) and have not invaded deeper tissues.
• Stage I: In Stage I, the melanoma is considered thin:
  • The tumor is no thicker than 1 millimeter (1/25 inch) and may show signs of ulceration (a scraped appearance).
  • Alternatively, the tumor measures between 1 and 2 millimeters thick without ulceration, and melanoma cells have not spread to nearby lymph nodes.
• Stage II: At this stage, the tumor is at least 1 millimeter thick:
  • It may be between 1 and 2 millimeters thick and present with ulceration.
  • Alternatively, the tumor may be greater than 2 millimeters thick, potentially with ulceration, but has not yet spread to nearby lymph nodes.
• Stage III: This indicates that melanoma has spread to nearby lymph nodes or to tissues just outside the original tumor without affecting the lymph nodes.
• Stage IV: At this advanced stage, melanoma cells have metastasized to other organs, lymph nodes, or distant skin areas.
• Recurrent: Recurrent disease indicates that cancer has returned after treatment, either in the original site or in a new location within the body.

There are various approaches to treating skin cancer, and your oncologist will work closely with you to determine the most effective combination of therapies based on the stage of cancer and your overall health. We at El Portal Comprehensive Cancer Centers are dedicated to providing you with comprehensive care tailored to your needs, ensuring you receive the support, guidance, and treatment necessary for your journey toward recovery.

Nonmelanoma Skin Cancer Treatments

In some cases, the entire nonmelanoma skin cancer may be removed during the biopsy, which means no further treatment is necessary. However, if additional treatment is required, your doctor will outline the available options.

There are six primary types of nonmelanoma skin cancer treatments, which may be used individually or in combination:

1. Surgery
2. Chemotherapy
3. Photodynamic therapy
4. Radiation therapy
5. Biologic therapy
6. Targeted therapy

Melanoma Skin Cancer Treatments

Melanoma treatment encompasses nearly all the same options as nonmelanoma skin cancer, with the exception of photodynamic therapy.

Skin Cancer Treatment Options

Your oncologist can provide detailed explanations of the following surgical techniques:

• Wide-Local Excision (WLE): This common approach involves numbing the area and surgically removing the cancer along with a margin of surrounding healthy skin. The margin is examined microscopically to ensure all cancer cells have been excised, and the required margin size will depend on the tumor’s dimensions. In some cases, nearby lymph nodes may also be removed.
• Mohs Surgery: This technique is particularly beneficial for skin cancer treatment. The surgeon numbs the area and removes thin layers of the tumor, examining each layer under a microscope for cancer cells. The process continues until no cancerous cells are detected, ensuring complete tumor removal while preserving as much healthy tissue as possible.
• Electrodesiccation and Curettage: This method is ideal for small basal cell skin cancers. The doctor numbs the area, removes the cancer using a curette (a spoon-shaped surgical instrument), and then employs an electric current to control bleeding and eliminate any remaining cancer cells. This procedure tends to be quick and straightforward.
• Cryosurgery: This option is suitable for patients who may not tolerate other surgical methods. Cryosurgery employs extreme cold, typically generated from liquid nitrogen, to treat early-stage or very thin skin cancer lesions. While effective, this approach may cause swelling and could damage nerves in the area, leading to temporary loss of sensation.
• Laser Surgery: This technique involves using a focused beam of light to target and destroy cancer cells. It is primarily utilized for superficial growths confined to the outer layer of skin.
• Skin Grafting: Occasionally, grafts are necessary to cover openings left by surgical removal. In this procedure, the surgeon numbs the area and removes a patch of healthy skin from another part of your body, such as the thigh, to cover the excised area. It is important to provide special care to the graft site during the healing process.
• Lymphadenectomy: This surgical procedure may be employed in the case of melanoma, wherein lymph nodes are removed for evaluation. The removed tissue is examined under a microscope for cancer cells.
• Sentinel Lymph Node Biopsy: During this procedure, the sentinel lymph node—the first node likely to receive cancer spread from the tumor—is surgically removed. A radioactive substance and/or blue dye is injected near the tumor site to track the flow to the lymph nodes. If no cancer cells are found in the sentinel node, additional nodes may not need to be excised, making this a useful technique within melanoma treatment plans.
