Treatment of Cecal Cancer in Israel

About the Disease

Cecal cancer is a malignant neoplasm that develops from the epithelial cells of the mucous membrane of this part of the intestine. The tumour is characterized by uncontrolled growth, invasion into adjacent tissues, and the ability to metastasize. Most cases are adenocarcinomas. Other types include mucinous adenocarcinoma, which produces excess mucus, signet-ring cell carcinoma with specific morphology, and the rarely encountered squamous cell carcinoma, which develops from metaplastic epithelium.

Causes

• Genetic predisposition
• Polyps and adenomas
• Inflammatory bowel diseases
• Improper diet low in fiber
• Smoking and alcohol

Symptoms

• Pain in the right iliac region
• Blood in stool
• Anemia
• Weight loss
• Constipation or diarrhea

Treatment Methods for Cecal Cancer

At the Ichilov Clinic, the choice of treatment methods for cecal cancer is based on comprehensive diagnostics that determine the stage of the disease, the size of the tumour, the presence of metastases, and the overall condition of the patient, after which a multidisciplinary team of oncologists develops a personalized therapy protocol.

Surgical Removal of the Tumour

When the disease is diagnosed at early stages and the neoplasm is confined to the intestinal wall, surgery becomes the primary method of combating the pathology. The operation involves excising the affected area of the cecum along with surrounding tissues and regional lymph nodes, which helps prevent the spread of atypical cells. Ichilov employs modern laparoscopic techniques that minimize trauma to healthy structures and reduce the patient's recovery period. Surgeons use high-precision imaging equipment to control the resection margins, ensuring the most radical removal of malignant tissues while preserving intestinal functionality.

Laparoscopic Organ-Sparing Surgery

At the earliest stages of the disease, when the tumour has not yet penetrated deeply into the intestinal wall and has not spread to the lymph nodes, Israeli surgeons prefer minimally invasive interventions. The neoplasm is excised within healthy tissues through several small punctures in the anterior abdominal wall, significantly reducing the trauma of the procedure compared to traditional open surgery. The use of high-resolution endoscopic equipment allows the surgeon to visualize the surgical field in detail and perform precise manipulations with meticulous accuracy. Patients after such interventions experience significantly less pain, return to normal activity more quickly, and have better cosmetic results due to the absence of large incisions on the abdomen.

Formation of Intestinal Anastomoses and Stomas

After removing the affected area of the cecum, surgeons restore the continuity of the digestive tract by connecting healthy ends of the intestine. Creating an anastomosis requires high skill, as the quality of the connection affects the risk of postoperative complications and the speed of recovery of intestinal function. In cases where there is an increased likelihood of anastomotic failure or time is needed for the connection to heal, doctors form a temporary colostomy, bringing a section of the intestine to the anterior abdominal wall to divert intestinal contents. Modern techniques allow, in most situations, to subsequently restore the natural passage through the intestine, closing the colostomy a few months after the main operation, when the tissues have completely healed and the body has recovered from intensive treatment.

Chemotherapeutic Impact

The use of cytostatic drugs is justified in advanced forms of the disease or high risk of recurrence after surgery. This approach helps destroy cancer cells that may have spread beyond the primary focus, reducing the likelihood of disease recurrence. Doctors prescribe combinations of antitumor agents from various pharmacological groups that enhance each other's effects and attack malignant structures at different stages of their life cycle. The duration of courses and intervals between them are determined individually, taking into account the tolerability of therapy and the dynamics of laboratory indicators. Modern protocols include supportive therapy to minimize side effects and maintain quality of life during treatment.

Neoadjuvant Chemotherapy

When the tumour is significantly sized or invades adjacent organs, making it technically difficult to remove, chemotherapy is prescribed before surgical intervention to reduce the volume of the neoplasm. Cycles of preoperative treatment with cytostatics help convert the neoplasm into a more resectable state, increasing the chances of performing a radical operation and reducing the risk of intraoperative complications. The reduction of tumour mass under the influence of drugs also allows surgeons to preserve a larger volume of healthy tissues and perform a less traumatic intervention. The effectiveness of neoadjuvant therapy is carefully monitored using imaging methods, allowing timely adjustments to the treatment protocol in case of insufficient response of the tumour to the applied cytostatic regimens.

Hyperthermic Intraperitoneal Chemotherapy

Immediately after surgical removal of the tumour, when there is a risk of microscopic cancer cells or micrometastases in the abdominal cavity, an innovative procedure called HIPEC is applied. The abdominal cavity is washed with a heated solution of chemotherapeutic agents, creating a dual destructive effect on residual malignant structures. Heating enhances the penetration of cytostatics into tissues and increases the sensitivity of cancer cells to their effects, while direct contact of the drugs with the surface of the organs ensures maximum concentration of active substances precisely where they are most needed. This method significantly reduces the likelihood of peritoneal carcinomatosis and improves long-term treatment outcomes in patients at high risk of disease spread in the peritoneum.

Targeted Therapy with Monoclonal Antibodies

In advanced stages, when traditional chemotherapy is insufficiently effective, innovative targeted drugs based on monoclonal antibodies come into play. They block specific molecular pathways necessary for the growth and division of cancer cells, while practically not affecting healthy tissues of the body. Before prescribing such agents, molecular-genetic testing of the tumour is conducted to identify specific mutations and protein markers that determine sensitivity to certain groups of drugs. Targeted agents are often combined with classical cytostatics, creating a synergistic effect and increasing the chances of disease control even in the presence of distant metastases in the liver or lungs.

Angiogenesis Inhibitors

In advanced forms of the disease with multiple metastases, drugs that block the formation of new blood vessels in the tumour tissue play a special role. Malignant neoplasms require a constant blood supply to grow, bringing oxygen and nutrients, and actively stimulate the process of angiogenesis, creating their own vascular network. Angiogenesis inhibitors cut off this vital process for the tumour, depriving it of necessary supplies and leading to a slowdown or cessation of tumour growth. Such drugs are often used in combination with chemotherapy and other targeted agents, enhancing the overall antitumor effect and prolonging the period of disease control in patients with metastatic forms of cecal cancer.

Immunotherapeutic Approach

When genetic analysis reveals microsatellite instability in the tumour, opportunities arise for the use of immunological agents. These modern agents activate the body's own defense system, teaching it to recognize and attack malignant cells that previously successfully masked themselves from immune surveillance. The mechanism of action is based on blocking immune checkpoints, which removes restrictions from T-lymphocytes and allows them to effectively destroy tumour structures. The results of such therapy can be impressive even in advanced disease, providing long-term disease control and improving survival prognosis in patients with certain molecular characteristics of the neoplasm.

External Beam Radiation Therapy

Irradiation of tumour foci using linear accelerators is used to reduce the size of the neoplasm before surgery or to lower the risk of recurrence after surgical treatment. Modern devices allow for the formation of ionizing radiation beams with high precision, concentrating the dose maximally in the area of the tumour while minimizing the impact on surrounding healthy organs in the abdominal cavity. Radiation therapy planning is carried out using three-dimensional modeling based on computed tomography data, ensuring optimal dose distribution. Fractionated irradiation with small doses over several weeks allows for the accumulation of a sufficient total dose to damage the DNA of cancer cells, while allowing healthy tissues to recover between sessions.

Contact Brachytherapy

In certain clinical situations, when it is necessary to deliver a high dose of radiation directly to the tumour focus with minimal irradiation of surrounding structures, the method of introducing radioactive isotopes directly into the affected tissues is used. Radiation sources are placed in close proximity to malignant cells or inside them, creating an extremely high local concentration of radiation while sharply reducing the dose at a distance of a few millimeters from the source. This is especially valuable when it is necessary to irradiate hard-to-reach areas or when it is important to preserve the function of nearby critical structures. The procedure can be performed either with temporary introduction of radioactive elements for a certain period or with their permanent implantation, depending on the clinical situation and the isotopes used.

Intraoperative Radiotherapy

Immediately during the surgical intervention, right after the removal of the main tumour mass, a single irradiation of the surgical field with high doses of radiation is performed to destroy residual cancer cells. This approach allows for the delivery of the maximum dose of radiation precisely to the risk zone, when surrounding organs are temporarily displaced by the surgeon and protected from radiation exposure. The method is especially effective for hard-to-reach locations of neoplasms or when complete removal of the tumour is technically impossible due to the proximity of vital structures. Intraoperative irradiation significantly reduces the likelihood of local recurrence, as microscopic clusters of malignant cells, invisible to the surgeon's eye, receive a lethal dose of radiation at the moment of maximum tissue vulnerability.

Stereotactic Radiosurgery

For patients for whom traditional surgical intervention is contraindicated due to the severity of comorbidities or complex localization of the tumour, a non-surgical treatment method using high-precision irradiation is available. Multiple thin beams of ionizing radiation are directed at the neoplasm from various angles and focused in its center, creating a zone of extremely high radiation dose that literally burns atypical cells. At the same time, each individual beam carries a relatively small dose and practically does not damage healthy tissues along its path, but at the intersection point of all beams, the dose becomes destructive for the tumour. In just a few sessions, local control over the neoplasm can be achieved without any incisions, blood loss, or the need for anesthesia, making the method ideal for weakened patients and treating metastatic foci.

Diagnostic Methods for the Disease

The foundation of successful therapy for cecal cancer is accurate diagnostics, necessary for the precise determination of the stage, size of the neoplasm, and extent of its spread. At Ichilov, all examinations are performed on high-precision expert-class equipment. This guarantees the ability to detect even minor pathological changes and identify metastases at early stages. A significant advantage of the examination at the clinic is the timely planning and prompt execution of all procedures, allowing for complete diagnostic information to be obtained and quickly transitioning to effective treatment.

First Day

Upon arrival, the patient is directed to a primary consultation with the treating oncologist, who coordinates the entire process. The doctor thoroughly studies the medical history (symptoms, heredity, comorbidities), conducts a physical examination (palpation of the abdomen, assessment of the condition). Based on this information, the oncologist develops an individual examination plan, determining the necessary diagnostic procedures for complete staging of the disease.

Second Day

The patient undergoes a comprehensive examination, including the full range of modern diagnostic methods:

• Expanded clinical blood test
• Biochemical blood analysis
• Analysis for tumor markers
• Stool test for hidden blood
• Colonoscopy with biopsy
• Histological examination of the biopsy
• Immunohistochemical analysis of the tumor tissue
• Molecular genetic testing
• Computed tomography of the abdomen and pelvis with contrast
• Magnetic resonance imaging
• Positron emission tomography combined with CT
• X-ray of the chest organs
• Ultrasound examination of the abdominal organs
• Endoscopic ultrasound examination

Third Day

To discuss the examination results, the treating physician initiates a multidisciplinary consultation, including surgical oncologists, chemotherapists, and radiologists. Experts collectively analyze the data, determine molecular-genetic characteristics, and choose the optimal treatment strategy, following international standards.
