taxane and Carcinoma--Papillary

To evaluate patterns of relapse in early stage uterine papillary carcinoma (UPSC) patients receiving adjuvant intravaginal radiotherapy (IVRT) with or without chemotherapy.. From 1/1996 to 12/2010, 77 women with stage I-II UPSC underwent surgery followed by IVRT (median 21Gy). Stage IA patients without residual disease at surgery were excluded. IVRT and chemotherapy (carboplatin/taxane) was given to 61 (79%) patients and IVRT alone to 16 (21%). The median follow-up was 62 months for surviving patients.. Of the 77 patients, 11 (14%) relapsed as follows: vaginal 2 (3%), pelvic 5 (6%), para-aortic 5 (6%), peritoneal 6 (8%), and other distant sites 8 (10%). Of the 5 pelvic relapses, 2 were isolated and were salvaged. In those treated without chemotherapy, only 1/16 developed recurrence (mediastinal). The 5-year vaginal, pelvic, para-aortic, peritoneal, and distant recurrence rates were 2.7% (C.I. 0-6.2%), 5.8% (C.I. 0.6-11.0%), 5.4% (C.I. 0.6-10.1%), 5.3% (C.I. 0.5-10.1%) and 6.6% (C.I. 1.4-11.8%), respectively. The 5-year disease-free survival (DFS), and overall survival (OS) were 88% (C.I. 81-95%), and 91% (C.I. 84-97%), respectively. The only predictor of worse 5-year pelvic control was stage (96.2% stage IA vs 87.7% for stage IB-II, p=0.043).. In stage I-II UPSC patients who predominantly receive adjuvant chemotherapy, IVRT as the sole form of adjuvant RT provides excellent locoregional control. The risk of isolated pelvic recurrence is too low to warrant routine use of external pelvic RT.

Stage I-II uterine papillary serous carcinoma (UPSC) patients have a significant risk for extrapelvic recurrence. However, clinicopathologic risk factors for recurrence are not well understood. This study was undertaken to define the prognostic factors for recurrence and survival in patients with early-stage UPSC.. A retrospective, multi-institution analysis of surgically staged I-II UPSC patients was performed. Patients were treated by various adjuvant modalities. Age, race, sub-stage, percentage UPSC histology, lymphvascular space invasion (LVSI), tumor size and adjuvant treatment modality were evaluated for their effect on recurrence and survival outcomes.. We identified 206 patients. Forty patients (19.4%) had 5-49% UPSC, 55 (26.7%) had 50-99% and 111 patients (53.9%) had 100% UPSC in their respective uterine specimens. Twenty one percent of patients experienced a primary recurrence. On univariate analysis, age, increasing %UPSC, LVSI, and tumor size were not significantly associated with recurrence or progression-free survival (PFS). However, substage (p=0.005) and treatment with platinum/taxane-based chemotherapy (p=0.001) were associated with recurrence/PFS. On multivariate analysis, only chemotherapy (p=0.01) was a significant factor affecting PFS, whereas age (p=0.05), substage (p=0.05), and chemotherapy (p=0.02) were associated with overall survival.. Traditional risk factors for recurrence and survival in patients with early-stage endometrial cancer may not be relevant in patients with UPSC. Patients with any percentage UPSC in their uterine specimens are at a significant risk for recurrence and poor survival outcomes. Given that current clinicopathologic data does not accurately identify women most likely to benefit from adjuvant therapy, alternative prognostic markers based on novel techniques should be explored.
