          Abstract

          The aim of the study was to investigate the long-term oncological outcomes of laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) for treatment of stage IA2 to IIA2 cervical cancer.

          Prospective surgical-pathological study of disease-free interval in patients with stage IB squamous cell carcinoma of the cervix: a Gynecologic Oncology Group study.

          There were 732 evaluable patients with primary, previously untreated, histologically confirmed stage I squamous carcinoma of the cervix with greater than or equal to 3-mm invasion. Of these, 645 had no gross disease beyond the cervix/uterus, had negative paraaortic lymph nodes, and had undergone a radical hysterectomy with pelvic lymphadenectomy. The 3-year disease-free interval (DFIs) for the 545 patients with negative pelvic nodes was 85.6%, and for the 100 with positive pelvic nodes, 74.4%. A large number of pelvic nodes involved with tumor was not correlated with a poorer prognosis; the DFIs were 72.1, 86.4, and 64.6% for one, two, and three or more positive pelvic nodes, respectively. DFI correlated strongly with depth of tumor invasion, both in absolute terms (mm) and infractional thirds. The DFI was 94.6% for less than or equal to 5 mm, 86.0% for 6-10 mm, 75.2% for 11-15 mm, 71.5% for 16-20 mm, and 59.5% greater than or equal to 21 mm. In fractional terms, the DFI was 94.1% for superficial third, 84.5% for middle third, and 73.6% for deep third invasion. With respect to clinical tumor size, the DFIs were 94.8, 88.1, and 67.6% for occult, less than or equal to 3 cm, and greater than 3 cm, respectively. The DFI was 77.0% for those with positive capillary-lymphatic spaces (CLS) and 88.9% for those with negative CLS. Tumor grade and parametrial status correlated with DFI. DFI was not significantly different for age, disease status of the surgical margins, tumor description (e.g., exophytic), quadrant involved with tumor, uterine extension, and keratinizing status of tumor cells. Clinical tumor size, CLS, and depth of tumor invasion were independent prognostic factors.

            Classification of radical hysterectomy.

            Since the first publications about surgery for cervical cancer, many radical procedures that accord with different degrees of radicality have been described and done. Here, we propose a basis for a new and simple classification for cervical-cancer surgery, taking into account the curative effect of surgery and adverse effects, such as bladder dysfunction. The international anatomical nomenclature is used where it applies. For simplification, the classification is based only on lateral extent of resection. We describe four types of radical hysterectomy (A-D), adding when necessary a few subtypes that consider nerve preservation and paracervical lymphadenectomy. Lymph-node dissection is considered separately: four levels (1-4) are defined according to corresponding arterial anatomy and radicality of the procedure. The classification applies to fertility-sparing surgery, and can be adapted to open, vaginal, laparoscopic, or robotic surgery. In the future, internationally standardised description of techniques for communication, comparison, clinical research, and quality control will be a basic part of every surgical procedure.

              Laparoscopic versus open radical hysterectomy in early-stage cervical cancer: long-term survival outcomes in a matched cohort study.

              To compare the long-term survival outcomes between laparoscopic radical hysterectomy (LRH) and open radical hysterectomy (ORH). We matched patients with stage IA2 to IIA cervical cancer with known risk factors for recurrence who underwent ORH and LRH. Compared with ORH (n = 263), LRH (n = 263) did not have higher risks of recurrence [hazard ratio (HR) = 1.28; 95% confidence interval (CI) 0.62-2.64] or death (HR = 1.46; 95% CI 0.62-3.43). Even in patients with tumors >2 cm in diameter, the risks of recurrence (HR = 0.82; 95% CI 0.31-2.16) or death (HR = 1.01; 95% CI 0.35-2.95) were not higher for LRH than for ORH. The LRH and ORH group had 5-year recurrence-free survival rates of 92.8% and 94.4%, respectively (P = 0.499). LRH resulted in significantly lower estimated blood loss (379.6 versus 541.1 ml, P < 0.001) and shorter postoperative hospital stay (12.5 versus 20.3 days, P < 0.001). Intraoperative complication rates were similar in the two groups (6.8% versus 5.7%, P = 0.711), but postoperative complication rate was lower in the LRH than in the ORH group (9.2% versus 21%, P < 0.001). LRH is an oncologically safe alternative to ORH and was associated with fewer postoperative complication and earlier recovery.
