Objective: To evaluate survival and recurrence in stage II endometrial cancer in relation to uterine risk stratification. Outcome for stage II was compared before and after the introduction of lymph node (LN) resection and omission of all postoperative radiotherapy. Methods: The cohort consisted of 4,380 endometrial carcinoma patients radically operated (no visual tumor, all distant metastasis removed) (2005–2012) including 461 stage II. Adjusted Cox regression was used to compare survival and actuarial recurrence rates. Results: Uterine risk factors (low-, intermediate-, and high-) were the strongest predictors of survival and recurrence in stage II. Stage II low-risk having a prognosis comparable to low-risk stage I (grade 1–2, <50% myometrial invasion), whereas cervical invasion significantly increased the risk of recurrence and decreased cancer-specific survival in intermediate- and high-risk compared to the corresponding stage I risk groups. In 355 cases of 708 with cervical stromal invasion, LN-resection showed 27.9% with LN metastasis and upstaged 18.1% from stage II to IIIC resulting in longer survival and lower recurrence in LN-resected compared to non-LN resected stage II. Radical as compared to simple hysterectomy did not alter survival. Treatment with external beam radiotherapy decreased local recurrence without affecting survival. Conclusion: Uterine risk groups are the strongest predictors for survival and recurrence in stage II patients and should be considered when advising adjuvant therapy. LN-resected stage II had increased survival and decreased recurrence. Omitting radiotherapy increase vaginal recurrence without affecting survival.

Objective: To evaluate the effect of lymph-vascular space invasion (LVSI) on location of recurrences in Danish patients with endometrial cancer. Methods: This national cohort study (2005–2012) included 4,380 radically operated patients (no visual tumor, all distant metastasis removed). LVSI status was recorded in 3,377 (77.1%). In stage I patients, 2.6% received adjuvant radiotherapy and 1.4% adjuvant chemotherapy. Adjusted Cox regression was used to compare actuarial recurrence rates. Results: LVSI was present in 18.7% of 3,377 patients with known LVSI status. Of these, 7.6% stage I patients with LVSI experienced an isolated locoregional and 19.4% a non-locoregional recurrence. Compared to no LVSI, 5-year recurrence rate was higher (25.5% vs. 8.5%) in patients with LVSI and the frequency of distant recurrences was strikingly higher (stage I: 15.2% vs. 2.7%), the effect being similar across International Federation of Gynecology and Obstetrics stages and histological types. In intermediate-risk stage I patients with LVSI, 8.0% experienced an isolated locoregional recurrence compared to 20.1% with non-locoregional recurrence, giving these patients a seriously adverse risk of survival. A separate analysis in patients with recurrences demonstrated that those with LVSI had significantly more distant recurrences (55.4% vs. 29.9%) and fewer isolated vaginal recurrences (24.3% vs. 42.8%) than patients with no LVSI. Conclusion: LVSI is a strong independent risk factor for the development of non-locoregional recurrences even in intermediate-risk stage I endometrial cancer. The non-locoregional recurrence pattern suggests a future focus for optimization of postoperative treatment in these patients.
