To determine the efficacy of high-dose rate brachytherapy as adjuvant treatment for Stage I/II papillary serous or clear cell endometrial cancer.
A retrospective study of all patients with Stage I/II papillary serous or clear cell endometrial cancer treated with high-dose rate brachytherapy between 1995 and 2001 was performed. Following surgical staging, which included hysterectomy with pelvic and aortic lymphadenectomy, all patients without extrauterine disease were treated with high-dose rate brachytherapy and followed for recurrence. The locations of recurrences were noted and were classified as local or distant.
Three (13%) recurrences occurred among 24 patients with Stage I/II papillary serous or clear cell carcinoma. The risk of recurrence was similar for papillary serous and clear cell cancer (12% vs. 12%). Local control was achieved in 96%. The risk of recurrence for those with no myometrial invasion, less than 1/2, or more than 1/2 myometrial invasion was 0%, 10%, and 50%, respectively (P < 0.04). Two of the three recurrences were distant and all patients with recurrence died despite additional treatment.
High-dose rate brachytherapy (HDR) as the sole adjuvant treatment of Stage I/II papillary serous or clear cell carcinoma is associated with a 13% risk of recurrence. Although local control with HDR is excellent, the risk of distant recurrence is increased with deep myometrial invasion. High-dose rate brachytherapy is adequate for Stage IA cases, but more aggressive treatment combining chemotherapy with HDR should be evaluated for more advanced Stage I/II cases.

    ABSTRACT: To assess the role of surgical staging, adjuvant therapy, and cytoreduction in uterine clear cell carcinoma (UCCC). A retrospective review was conducted at 2 major gynecologic cancer centers of all primary UCCC between 1982 and 2004. UCCC was confirmed in 99 patients. The 5-year overall survival (OS) was 79%, 77%, 47%, and 21% for stages I-IV respectively. 69 patients had no gross evidence of extra-uterine disease, but 36 (52%) were upstaged at surgery. For those 22 patients with stages I and II disease who had a systematic lymphadenectomy (LND) (> 20 lymph nodes), no lymphatic (LF), peritoneal (PF), or hematological (HF) failures were noted. Radiation (RT) improved PFS (67 vs. 36%, p=0.02), and reduced pelvic sidewall recurrences (18 vs. 53%, p=0.04) and vaginal failures (VF) (7 vs. 35%, p=0.04) for 45 patients at risk for LF (positive nodes or suboptimal LND). 39 patients with stages IIIC and IV disease were separately analyzed. Patients with no visible residual disease after cytoreduction had a significant improvement in median PFS (17 vs. 7 months, p<0.001), and OS (40 vs. 18 months, p=0.02) compared to patients with any residual disease after surgery. Comprehensive surgical staging with a systematic LND is essential to accurately define early stage UCCC. Vaginal brachytherapy may be adequate adjuvant therapy for stages I and II UCCC confirmed by systematic LND. Patients at risk for LF appear to benefit from pelvic RT. An effort at cytoreduction to no visible residual disease should be made in advanced UCCC when feasible.

    ABSTRACT: To report a single institution experience in surgical stage I-II serous endometrial cancer using combined carboplatin/paclitaxel and intravaginal radiation (IVRT). Between 10/00 and 12/06, 25 stage I-II patients with serous endometrial cancer were treated at our institution with surgery, postoperative IVRT, and concurrent chemotherapy (CT). The mean age was 67 years old (range, 53-80 years). Surgery consisted of hysterectomy (TAH/BSO, 64%, LAVH/BSO, 36%), peritoneal washing, omental biopsy, and pelvic lymph-node dissection (median 14 nodes). Para-aortic node sampling was done in 88% (median, 6). IVRT median dose was 21 Gy (range, 18-21 Gy, in 3 fractions) and concurrent CT consisted of carboplatin to AUC=5 and taxol to 175 mg/m(2) given every 3 weeks for 6 cycles. CT was well tolerated with 22/25 (88%) receiving 6 cycles. Three patients received <or=5 cycles; 2 owing to physician preference (3 and 4 cycles) and 1 owing to toxicity (5 cycles). Only 1 patient (4%) had grade 3 toxicity (abscess). Grade 2 neurotoxicity was seen in 5 patients (20%). All patients finished their IVRT as scheduled, and there was no grade 3 toxicity. With a median follow-up of 30 months, the 5-year progression-free and overall survival rate was 88%. None of the patients developed vaginal recurrence. Based on this study, surgical staging followed by IVRT and carboplatin/paclitaxel is well tolerated and effective in stage I-II serous endometrial cancer. Confirmation of these results on a larger number of patients with longer follow-up is still needed.

    ABSTRACT: Uterine papillary serous carcinoma (UPSC) is a clinically and pathologically distinct subtype of endometrial cancer. Although less common than its endometrioid carcinoma (EEC) counterpart, UPSC accounts for a disproportionate number of endometrial cancer related deaths. To date, limited prospective trials exist from which evidence-based management can be developed. This review summarizes the available literature concerning UPSC in an effort to provide the clinician with information pertinent to its management.
