Objective
Adjuvant radiotherapy improves local control but not survival in women with endometrial cancer. This benefit was shown in staged patients with "high intermediate risk" (HIR) disease. Other studies have challenged the need for systematic staging including lymphadenectomy. We sought to determine whether LVSI alone or in combination with other histologic factors predicts lymph node (LN) metastasis in patients with endometrioid endometrial cancer.
Methods
A retrospective review was conducted of patients with endometrioid endometrial carcinoma who had confirmed presence/absence of LVSI and clinicopathologic data necessary to identify HIR criteria. Kaplan-Meier curves were generated and univariate and multivariate analyses performed as appropriate.
Results
We identified 757 eligible patients and 628 underwent systematic lymphadenectomy for staging purposes. In the surgically staged group, 242 (38%) patients met uterine HIR criteria and 196 (31%) had LVSI. Both HIR and LVSI were significantly associated with LN metastasis. Among the HIR positive group, 59 had LN metastasis (OR 4.46, 95% CI 2.72–7.32, P<0.0001). Sixty-six LVSI positive patients had nodal metastasis (OR 11.04, 95% CI 6.39–19.07, P<0.0001). The NPV of LVSI and HIR negative specimens was 95.6% and 93.4% respectively. In multivariate analysis, PFS and OS were significantly reduced in both LVSI positive (P<0.0001) and HIR patients (P<0.0001) when compared to patients who were LVSI and HIR negative
Conclusions
HIR status and LVSI are highly associated with LN metastasis. These features are useful in assessing risk of metastatic disease and may serve as a surrogate for prediction of extrauterine disease.
Objective
The profile of women with gynecologic malignancies treated with pelvic exenteration has changed since the initial description of this procedure. We sought to evaluate our experience with pelvic exenteration over the last 20 years.
Methods
Patients who underwent anterior, posterior, or total pelvic exenteration for vulvar, vaginal, and cervical cancer at Barnes-Jewish Hospital between January 1, 1990 and August 1, 2009 were identified through hospital databases. Patient characteristics, the indications for the procedure, procedural modifications, and patient outcomes were retrospectively assessed. Categorical variables were analyzed with chi-square method, and survival data was analyzed using the Kaplan-Meier method and log rank test.
Results
Fifty-four patients were identified who had pelvic exenteration for cervical, vaginal, or vulvar cancer. Recurrent cervical cancer was the most common procedural indication. One year overall survival from pelvic exenteration for the entire cohort was 64%, with 44% of patients still living at 2 years and 34% at 50 months. Younger age was associated with improved overall survival after exenteration (p = 0.01). Negative margin status was associated with a longer disease-free survival (p = 0.014). Nodal status at the time of exenteration was not associated with time to recurrence or progression, site of recurrence, type of post-operative treatment, early or late complications, or survival.
Conclusions
Despite advances in imaging and increased radical techniques, outcomes and complications after total pelvic exenteration in this cohort are similar to those described historically. Pelvic exenteration results in sustained survival in select patients, especially those that are young with recurrent disease and pathologically negative margins.
Background
The effect of body mass index (BMI) on treatment outcomes for patients with locally advanced cervical carcinoma undergoing definitive chemoradiation is unclear.
Methods
This study cohort included all cervical carcinoma patients (n = 404) with stage IB1 and positive lymph nodes or stage ≥ IB2 treated at our facility from January 1998 to January 2008. Mean follow-up time was 47.2 months. BMI was calculated using the National Institute of Health online calculator. BMI categories were created according to the World Health Organization classification system. Primary outcomes were overall survival, disease free survival, and complication rate. Univariate and multivariate analyses were performed. Kaplan-Meier survival curves were generated and compared using Cox proportional hazard models.
Results
On multivariate analysis, when compared to normal weight subjects (18.5-24.9 kg/m2), a BMI < 18.5 kg/m2 was associated with decreased overall survival (HR 2.37, 95% CI 1.28 - 4.38, p<0.01). The 5-year overall survivals were 33%, 60%, and 68% for a BMI < 18.5 kg/m2, BMI 18.5-24.9 kg/m2, and a BMI > 24.9 kg/m2 respectively. A BMI < 18.5 kg/m2 was associated with increased risk for grade 3 or 4 complications when compared to patients with a BMI > 24.9 kg/m2 (radiation enteritis: 16.7% vs. 13.6 % p= 0.03, fistula: 11.1% vs. 8.8% p= 0.05, bowel obstruction 33.3% vs. 4.4% p< 0.001, lymphedema: 5.6% vs. 1.2% p=0.02).
Conclusions
Underweight patients (BMI < 18.5 kg/m2) with locally advanced cervical cancer have diminished overall survival and more complications than normal weight and obese patients.
