Changes in the demographics and perioperative care of stage IA(2)/IB(1) cervical cancer over the past 16 years.
The aim of this study was to determine whether there have been any significant changes in the demographics and perioperative care of FIGO stage IA(2)/IB(1) cervical cancer over the past 16 years and, if so, to quantify them.
Since July 1984, all patients with FIGO stage IA(2)/IB(1) cervical cancer undergoing radical surgery by members of our division have been entered into a prospective database. Selection for surgery has been unchanged over the past 16 years. Since March 1994 and November 1996, one surgeon has performed radical vaginal trachelectomy and laparoscopic assisted radical vaginal hysterectomy, respectively. Statistical analysis used Spearman's correlation analysis, the proportional hazards regression model of Cox, and the Mantel-Hanzel test was performed. Due to the number of statistical analyses, statistical significance was defined as P < 0.01.
Eight hundred sixty-four patients have undergone radical surgery (784 radical hysterectomy, 42 radical vaginal trachelectomy, 32 radical vaginal hysterectomy, 6 radical abdominal trachelectomy) for FIGO stage IA(2)/IB(1) carcinoma of the cervix by members of our division since 1984. There have been no changes in the median age (40 years), tumor size (2.0 cm), incidence of capillary lymphatic space involvement (47%), or positive pelvic lymph nodes (6%) over the past 16 years. The median Quetelet index (24.6), depth of tumor invasion (squamous cell carcinomas only) (6.0 mm), and proportion of patients with comorbid conditions (17%) have increased over time (P = 0.001, P = 0.003, and P < 0.001, respectively). Pathologically, there has been an increase in the proportion of adenocarcinomas (28%) and a decrease in the proportion of grade 3 tumors (28%) (P < 0.001 and P < 0.001, respectively). The median operating time (2.8 h), hospital stay (7.0 days), blood loss (600 cc), allogeneic blood transfusion (23%), postoperative infections (13%), and noninfectious complications (6%) have all decreased (P < 0.001, P < 0.001, P < 0.001, P < 0.001, P < 0.001, and P = 0.002, respectively). There has been no change in the incidence of positive surgical margins (3%), adjuvant radiation (13%), or recurrence-free survival (2 and 5 years, 94 and 90%, respectively) after a median follow-up of 45 months.
Despite no substantive changes in the selection criteria for surgery and the small time interval studied (16 years), almost all indices of operative and postoperative morbidity analyzed have decreased significantly. These changes have occurred without an increase in the use of adjuvant radiation or decrease in recurrence-free survival. Although little progress has been made in the cure rates associated with surgical management of FIGO stage IA(2)/IB(1) cervical cancer during this time interval, it appears that the morbidity of surgery has decreased.

Early adenocarcinoma of the cervix: is radical vaginal trachelectomy safe?
Radical vaginal trachelectomy (RVT) is a revolutionary option for fertility preservation in young women with early cervical tumors. Several series have demonstrated outcomes comparable to radical hysterectomy (RH), but none has addressed the influence of histology. We evaluated the safety of RVT in adenocarcinomas.
Data on surgically treated adenocarcinoma (AC) and squamous cell carcinoma (SCC) cases was taken from a centralized Toronto Cervical Cancer Database. Prognostically important tumor features, lymph node status, and the use of adjuvant therapies were compared. Adenocarcinoma cases treated with RVT were compared to AC cases treated with RH, and to SCC cases that had RVT. Recurrence-free survival was calculated from the date of surgery. Medians, proportions, and survival curves were compared with the Mann Whitney test, the Chi-square test, and the Log Rank test, respectively.
74 patients with AC and 66 patients with SCC undergoing RVT, and 187 cases of AC undergoing RH were analyzed. Patients undergoing RVT were younger than patients having RH (31 vs. 40, p<0.001). Tumor characteristics were similar, but depth of invasion and the frequency of high grade lesions were higher in the RH group (5 mm vs. 3 mm, p<0.001; and 36% vs. 22%, p=0.04). Adjuvant treatment was given more frequently after RH (12% vs. 3%, p<0.05). There was no significant difference in recurrence-free survival between RH and RVT for AC, or between AC and SCC patients treated by RVT.
RVT is a safe alternative for early stage cervical adenocarcinoma in appropriately selected patients wishing to preserve fertility.
