Uterine papillary serous carcinoma. A clinical study

Area of Science:

• Gynecologic Oncology
• Pathology
• Medical Oncology

Background:

• Uterine papillary serous carcinoma (UPSC) is an aggressive subtype of endometrial adenocarcinoma.
• UPSC presents at advanced stages and has a poorer prognosis than endometrioid adenocarcinoma.
• Characterized by papillary architecture and poor differentiation.

Purpose of the Study:

• To evaluate the history, treatment, and follow-up of patients with UPSC.
• To compare UPSC staging with endometrioid adenocarcinoma.
• To assess the efficacy of various treatment modalities, including chemotherapy.

Main Methods:

• Retrospective review of 18 women diagnosed with UPSC.
• Surgical management included total hysterectomy and bilateral salpingo-oophorectomy.
• Analysis of treatment outcomes based on FIGO stage and therapeutic interventions (radiotherapy, chemotherapy).

Main Results:

• 12 of 18 UPSC patients had advanced FIGO Stage III/IV disease, significantly higher than endometrioid adenocarcinoma (P < 0.001).
• Of 12 patients with Stage III/IV UPSC, 4 survived with no evidence of disease after treatment.
• Eight of 12 women receiving platinum-based chemotherapy (cisplatin/carboplatin plus cyclophosphamide) survived, including 4 with advanced disease.

Conclusions:

• Platinum-based chemotherapy demonstrates potential efficacy in managing UPSC.
• Further research is warranted to confirm the role of platinum-based chemotherapy in UPSC treatment.
• Early-stage UPSC patients showed no tumor-related deaths during follow-up.
