The Large Uterus Classification System: a prospective observational study.

OBJECTIVE: To investigate the Large Uterus Classification System (LUCS) ability to predict surgical outcomes and complications in total laparoscopic hysterectomies (TLHs) for large uteri. DESIGN: Prospective observational study. SETTING: Two referral centres. POPULATION OR SAMPLE: Three hundred and ninety-two women who underwent TLH for a large uterus (uterine fundus at or over the transverse umbilical line). METHODS: Between 2004 and 2019, the intraoperative LUCS was estimated in all patients. The LUCS considers the uterine and adnexal vascular pedicles displacement. Type 1 is without vascular pedicles displacement. Type 2 has the cephalad displacement of adnexal vascular pedicles. The uterine vessels displacement regardless of adnexal pedicles defines Type 3. MAIN OUTCOME MEASURES: Patients' characteristics with perioperative outcomes were prospectively collected and compared between the three types of large uteri. RESULTS: Two hundred and fifty-one (64%), 82 (20.9%) and 59 (15.1%) women had Type 1, Type 2 and Type 3 uteri, respectively. Women with Type 1 uteri had a lower uterine weight, shorter operative time, less blood loss and lower complication rates than women with Types 2 and 3. The conversion rate to laparotomy in Type 1 was similar to that in Type 2 (odds ratio [OR] 0.98; 95% CI 0.32-3.56) but lower than Type 3 (OR 0.35; 95% CI 0.14-0.97); in Type 2 it was lower than Type 3, although without the conventional statistical significance (OR 0.36; 95% CI 0.13-1.13; P = 0.07). Multivariable analysis showed that the uterine Type (1 versus 2-3) was independently associated with the total complications rate (OR 2.00; 95% CI 1.09-3.68; P = 0.02). CONCLUSIONS: The LUCS appears associated with surgical outcomes and complications, potentially stratifying the surgical risk and guiding the surgical technique in TLHs for large uteri. TWEETABLE ABSTRACT: The Large Uterus Classification System may predict outcomes in total laparoscopic hysterectomy of large uteri.

Robotic surgery for endometrial cancer: comparison of perioperative outcomes and recurrence with laparoscopy, vaginal/laparoscopy and laparotomy.

INTRODUCTION: Comparison of perioperative outcomes and recurrence in patients undergoing primary surgical treatment for endometrial cancer by robotics, laparoscopy, vaginal/laparoscopy, or laparotomy approaches. METHODS: Prospective analysis of 67 patients undergoing robotic surgery for endometrial cancer between March 2004 and December 2007. Comparison was made with similar patients operated between November 1999 and December 2006 by laparoscopy (37 cases), laparotomy (99 cases) and vaginal/laparoscopy approach (vaginal hysterectomy, bilateral adnexectomy/laparoscopic lymphadenectomy) (47 cases) and matched by age, body mass index (BMI), histological type and International Federation of Gynecologists and Obstetricians (FIGO) staging. RESULTS: Mean operating times for patients undergoing robotic, laparoscopy, vaginal/laparoscopy or laparotomy approach were 181.9, 189.5, 202.7 and 162.7 min, respectively (p = 0.006); mean blood loss was 141.4, 300.8, 300.0 and 472.6 ml, respectively (p <0.001); mean number of nodes was 24.7, 27.1, 28.6, and 30.9, respectively (p = 0.008); mean length of hospital stay was 1.9, 3.4, 3.5 and 5.6 days, respectively (p < 0.001). There were no significant differences in intra- or postoperative complications among the four groups. The conversion rate was 2.9% for robotics and 10.8% for the laparoscopy group (0.001). There were no differences relative to recurrence rates among the four groups: 9%, 14%, 11% and 15% for robotics, laparoscopy, vaginal/laparoscopy, and laparotomy, respectively. CONCLUSION: Robotics, laparoscopy and vaginal/laparoscopy techniques are preferable to laparotomy for suitable patients with endometrial cancer. Robotics is preferable to laparoscopy due to a shorter hospital stay and lower conversion rate and preferable to vaginal/laparoscopy due to a reduced hospitalization.

Molecular and cytokinetic pretreatment risk assessment in endometrial carcinoma.

OBJECTIVE: Our objective was to determine whether cytokinetic and molecular analyses of curettage specimens can provide a mechanism for triage of patients with endometrial cancer before initiating definitive surgical treatment. METHODS: Pretreatment analysis consisted of flow cytometric determination of ploidy, S-phase fraction (SPF), and proliferative index (PI) and immunohistochemical determination of expression of proliferating cell nuclear antigen, HER-2/neu, and p53 in curettage specimens from 134 patients with endometrial carcinoma who subsequently had surgical staging and definitive surgical treatment. Fisher's exact test or chi(2) was used to examine the association between pretreatment variables and traditional surgical-pathologic indices. The log-rank test was used for univariate survival analysis. Cox proportional hazards identified the most important molecular factors. RESULTS: Nondiploid status, SPF >/=9%, and PI >/=14% were associated with the traditional posttreatment prognostic indices, stage, grade, and histologic subtype. Univariate survival analysis demonstrated a correlation between nondiploid status, SPF >/=9%, PI >/=14%, and p53 overexpression and decreased progression-free survival (PFS) and disease-related survival (DRS). Stepwise Cox regression analysis identified p53 overexpression and SPF >/=9% as the most significant pretreatment molecular risk factors. A model stratifying patients according to whether none, one, or both of these two pretreatment factors were present showed that when both factors are present the risk for recurrence was higher (RR = 7.07; 95% confidence interval [CI], 3.06-16.38; P < 0.01) and death due to disease was higher (RR = 9.93; 95% CI, 3.92-25.19; P < 0.01) than when no factors are present. In the group with both factors, 5-year PFS and DRS estimates were 41 and 44%, respectively, compared with 86 and 86% and 90 and 92% for the "none" and "one" groups, respectively. CONCLUSION: When observed simultaneously, increased SPF and p53 overexpression defined a group of patients at high risk for rapid recurrence and death due to disease. Pretreatment molecular analysis of curettage specimens could provide a mechanism of triage that could be applied before definitive surgical treatment.
