Surgical Oncology
Oncological surgery is an advanced specialty focused on the surgical treatment of cancers of the abdominal organs, particularly those of the digestive system. The main goals are complete removal of the tumor, clearance of the surrounding lymph nodes in accordance with oncological principles, and preservation of organ function.
Overview
While laparoscopic and robotic techniques are preferred in early-to-intermediate stage cases, open surgery is also performed when needed in advanced cases. The treatment plan is shaped through a multidisciplinary board decision involving medical oncology, radiation oncology and pathology.
Who Is It For?
- Patients diagnosed with cancer of the pancreas, liver, stomach, colon, rectum, esophagus or small intestine
- Individuals in whom a suspicious mass is detected on screening or imaging
- Patients for whom surgery is planned after neoadjuvant (preoperative) chemotherapy/radiotherapy
- Patients with local recurrence or resectable metastasis who are deemed suitable by a multidisciplinary board
Treatment Process
- 1
Diagnosis & Staging
The stage of the disease and surgical resectability are determined using endoscopy, biopsy, CT/MRI/PET-CT and tumor markers.
- 2
Multidisciplinary Board
Surgery, medical/radiation oncology and pathology evaluate the case together; neoadjuvant treatment is planned if required.
- 3
Surgical Resection
The tumor is removed with clear surgical margins; regional lymph node dissection and, if needed, reconstruction are performed.
- 4
Adjuvant Treatment & Long-Term Follow-Up
Chemotherapy/radiotherapy is planned according to the pathology result; recurrence is screened for through regular check-ups.
Recovery & Aftercare
Recovery varies according to the extent of the operation and the patient's general condition. Early mobilization and enteral nutrition are scheduled.
Hospital Stay
3-10 days
Recovery Time
3-6 weeks
Follow-up
Every 3 months for the first 2 years
Frequently Asked Questions
Is robotic oncological surgery as effective as open surgery?
In appropriately selected patients and in experienced hands, robotic oncological surgery gives results equivalent to open surgery in terms of lymph node clearance and oncological margins.
Is chemotherapy given to every patient?
No. The decision on adjuvant chemotherapy is based on the pathology result, the stage, lymph node involvement and the patient's general condition.
When can a normal diet be resumed after the operation?
In digestive system surgery, fluids are started on the first day, with a gradual transition to soft and then normal foods in the following days. This period varies between 3 and 10 days depending on the operation.
What is the risk of recurrence?
The risk of recurrence depends on the stage of the tumor, its biological characteristics and adherence to adjuvant treatment. Regular follow-up is critically important for detecting recurrence early.
