Radical surgery is generally feasible for advanced cervical cancer, i.e., stage Ia to IIa by the International Society of Gynecology and Obstetrics (FIGO) staging. For patients with locally advanced, large cancer foci Ib2 to IIa2 (>4cm), surgical treatment is still controversial. What are the types of cervical cancer resection surgery? What is the extent of resection and what are the characteristics (size and location) of the respective tumors? The main types of surgery are as follows: Type I: extra-fascial total hysterectomy with excision of the vaginal vault, if present (for stage Ia1 patients, i.e. interstitial infiltration depth ≤ 3 mm and horizontal spread ≤ 7 mm). Type II: subextensive hysterectomy with resection also including the 1/2 sacral and main ligaments and part of the vagina (for stage Ia2 patients, i.e. interstitial infiltration depth >3 mm, but ≤5 mm, horizontal spread ≤7 mm ). Type III: Extensive hysterectomy, which also includes resection of the sacrum, main ligament and upper 1/3 of the vagina against the pelvic wall (standard radical surgery for cervical cancer, for patients with stage Ib-IIa, i.e., clinically visible tumor or preclinical tumor size exceeding the range of Ia, and no obvious parametrial invasion). Type IV: ultra extensive hysterectomy with additional resection of the superior bladder artery and 3/4 of the vaginal tissue compared to type III (rarely used, depending on the patient). Type V: pelvic organ contouring with removal of the distal ureter and part of the bladder tissue and with ureteral implantation (rarely used, depending on the patient). ” What type of cervical cancer can preserve the uterus and preserve fertility? In recent years, radical hysterectomy has been performed for some young patients with early stage cervical cancer who desire to have children in order to preserve the uterus and reproductive function, with the following indications: strong fertility requirements; no history of infertility; stage Ia1 with positive margins of previous conization, or stage Ia1 with lymphatic vascular invasion, or stage Ia2 to Ib1 patients; tumor maximum diameter not exceeding 4?cm and no regional lymph node metastasis. Pathological types include adenocarcinoma, squamous carcinoma, adenosquamous carcinoma, and certain cervical rhabdomyosarcomas; age less than 45 years; patients who are not suitable for vaginal surgery (e.g., patients who have undergone multiple vaginal cones and whose anatomy is destroyed, certain young girls who are not eligible for vaginal surgery, etc.). What tests do patients need to undergo before surgery and which indicators are relevant to surgery? 1. Clinical staging examination: “triple” palpation, visual examination and pulmonary examination are necessary for the diagnosis of each patient’s staging; gynecological examination requires two experienced doctors (at least one with an associate or higher title) to determine the staging after examination, and the surgical plan is mainly based on the clinical staging; patients with suspected pre-infiltrative lesions are feasible colposcopy, cervical canal scraping and other examinations. Laboratory tests: blood routine, liver and kidney function, coagulation function, urinalysis, etc.; abnormally elevated tumor markers can assist in diagnosis, efficacy evaluation, disease monitoring and post-treatment follow-up monitoring, and SCC is the most commonly detected serological tumor marker in cervical cancer diagnosis and treatment. 3.Imaging: pelvic and abdominal CT or MRI is recommended for stage Ib1 or above. Pelvic MRI with high soft tissue resolution is the best imaging method to show cervical lesions, which can clearly distinguish the boundary between lesions and surrounding normal structures; CT examination can observe whether there are metastases in lymph nodes and other organs in abdominopelvic cavity. Chest plain film or CT can exclude lung metastasis. 4.In case of clinical symptoms or signs and suspicion of bladder or rectal lesions, biopsy by cystoscopy or proctoscopy is required and confirmed by histological examination. 5.Fine needle aspiration of lymph nodes suspected by scan examination can help to develop treatment plan. 6.The optional tests are arteriography, venography, dissection, ultrasound exploration, PET/CT, etc.
