What is medical oncology surgery remains one of the leading causes of death worldwide. Fortunately, advancements in medical science have introduced a range of effective treatment options, one of which is medical oncology surgery. While the term “medical oncology” typically refers to non-surgical treatments like chemotherapy and immunotherapy, medical oncology surgery plays a pivotal role in cancer care by helping diagnose, stage, and treat tumors through surgical methods.
Fortunately, thanks to remarkable advancements in medical science and oncology, a wide range of treatment options is now available. These include chemotherapy, radiation therapy, immunotherapy, hormone therapy, targeted therapy, and surgery. Each approach plays a unique role in cancer care, and often, a combination of therapies offers the best outcome for the patient.
What is Medical Oncology Surgery?
Medical oncology surgery, often referred to as surgical oncology, is a branch of oncology that focuses on the surgical management of cancer. It involves the removal of tumors, cancerous tissues, and in some cases, surrounding tissues and lymph nodes to prevent the spread of cancer.
The goal of oncology surgery can vary:
-
Curative :- To completely remove the cancer.
-
Preventive :- To remove tissue that may develop into cancer (e.g., precancerous polyps).
-
Diagnostic :- To obtain a biopsy for confirming cancer type.
-
Staging :- To determine how far the cancer has spread.
-
Palliative :- To relieve symptoms or improve quality of life when a cure isn’t possible.
Key Differences Between Medical Oncology and Surgical Oncology
While often used interchangeably, medical oncology and surgical oncology are distinct disciplines:
-
Medical Oncology focuses on drug-based cancer treatments, including chemotherapy, immunotherapy, and targeted therapy.
-
Surgical Oncology involves physical removal of cancerous tumors or tissues through surgical procedures.
Both disciplines often work in tandem, providing a multidisciplinary approach to cancer care. For example, a patient may undergo surgery to remove a tumor and then receive chemotherapy to eliminate remaining cancer cells.
When is Oncology Surgery Recommended?
Medical oncology surgery is recommended in various scenarios, including:
-
Early-stage cancers that are localized and can be removed surgically.
-
Solid tumors such as breast, colon, prostate, lung, and ovarian cancers.
-
Benign tumors that may turn malignant over time.
-
To relieve symptoms in advanced-stage cancers (e.g., intestinal blockages).
-
To diagnose or confirm cancer through biopsy.
-
To stage the cancer by checking nearby lymph nodes or tissues.
Your oncologist and surgical team will assess your overall health, the type and stage of cancer, and other factors before recommending surgery.
Common Types of Medical Oncology Surgeries
Here are some common surgical procedures used in cancer treatment:
- Tumor Resection :- This involves removing the tumor and a margin of healthy tissue to ensure all cancer cells are eliminated.
- Lymph Node Dissection :- To check if cancer has spread, lymph nodes near the tumor site may be surgically removed.
- Mastectomy and Lumpectomy :- In breast cancer treatment, part or all of the breast tissue may be removed.
- Colectomy :- This involves removing part or all of the colon in cases of colon cancer.
- Lobectomy :- Surgical removal of a lobe of the lung in lung cancer patients.
- Hysterectomy :- Used in gynecological cancers, this surgery removes the uterus and sometimes surrounding organs.
- Cytoreductive Surgery :- Performed in advanced cancers to reduce the tumor load before chemotherapy or radiation.
Diagnostic Role of Oncology Surgery
Surgical intervention is often necessary for diagnosis. A biopsy, where a small piece of tissue is surgically removed and analyzed, is a key step in confirming the presence of cancer. There are several biopsy techniques:
-
Incisional biopsy (removing part of the tumor)
-
Excisional biopsy (removing the entire tumor)
-
Needle biopsy (using a needle to extract tissue, sometimes guided by imaging)
This helps doctors determine the cancer type, grade, and treatment options.
Pre-Surgical Preparation
Before undergoing medical oncology surgery, patients undergo a thorough evaluation including:
-
Medical history and physical examination
-
Blood tests and imaging scans (CT, MRI, PET)
-
Cardiac clearance if needed
-
Anesthesia evaluation
The medical team will discuss potential risks, benefits, and the expected outcome. Pre habilitation improving your physical fitness and nutrition before surgery may also be recommended.
What to Expect During Surgery
The specifics of surgery depend on the type, location, and stage of cancer. However, most procedures involve:
-
Anesthesia administration (general or local)
-
Surgical excision of tumor and possibly surrounding tissue
-
Monitoring of vital signs
-
Post-operative care in recovery unit or ICU
Advanced surgical techniques like minimally invasive laparoscopic surgery or robot-assisted surgery may be used for greater precision and faster recovery.
Post-Surgery Recovery and Care
Recovery time varies depending on the complexity of the surgery and the patient’s overall health. Common aspects include:
-
Pain management and wound care
-
Monitoring for infections or complications
-
Gradual return to normal activities
-
Follow-up visits to assess healing and plan next steps
-
Additional treatments like chemotherapy or radiation if needed
Patients are also advised to maintain good nutrition, stay physically active (as permitted), and attend regular oncology follow-ups.
Risks and Complications of Oncology Surgery
While oncology surgeries are generally safe, they do carry certain risks, such as:
-
Bleeding
-
Infections
-
Blood clots
-
Adverse reactions to anesthesia
-
Damage to surrounding organs or tissues
-
Delayed healing or scarring
Your surgeon will explain these risks in detail and take precautions to minimize them.
Role of Surgical Oncologists
Surgical oncologists are specially trained surgeons with expertise in cancer biology and advanced surgical techniques. They work closely with:
-
Medical oncologists
-
Radiation oncologists
-
Pathologists
-
Radiologists
-
Nursing teams
This collaborative team ensures that patients receive comprehensive and personalized care.
Benefits of Medical Oncology Surgery
-
Potential cure in early-stage cancers
-
Accurate diagnosis and staging
-
Reduced tumor size before other treatments
-
Relief from pain or discomfort
-
Improved survival rates when combined with other therapies
Conclusion
Medical oncology surgery is a cornerstone of cancer treatment and plays a vital role in the diagnosis, management, and potential cure of many cancers. When used in combination with chemotherapy, radiation, and immunotherapy, surgical intervention can significantly improve patient outcomes.
Equally important is the diagnostic role of surgical procedures like biopsies, which provide essential information for planning a personalized treatment approach. In modern cancer care, a multidisciplinary team of oncologists, surgeons, radiologists, and pathologists work collaboratively to determine the most effective combination of treatments, tailored to the individual needs of each patient.
