Isolated peripheral lymph node recurrence of endometrial carcinoma

Area of Science:

• Oncology
• Gynecologic Oncology
• Cancer Research

Background:

• The natural history of isolated endometrial carcinoma recurrence in peripheral lymph nodes (inguinal, axillary, supraclavicular) is not well-documented.
• This specific recurrence pattern is associated with higher initial surgical stage and tumor grade.

Purpose of the Study:

• To investigate the clinical characteristics, treatment outcomes, and prognostic factors of endometrial carcinoma recurring initially in isolated peripheral lymph nodes.
• To evaluate the effectiveness of aggressive local treatment strategies for these recurrences.

Main Methods:

• Retrospective review of 22 patients with isolated inguinal, axillary, or supraclavicular lymph node recurrence of endometrial carcinoma treated between 1963 and 1986.
• Analysis of treatment modalities including surgery, radiation, and systemic therapy, alongside patient outcomes and survival data.

Main Results:

• Supraclavicular and inguinal recurrences were equally frequent; axillary recurrences were rare.
• Local control was achieved in 15 out of 22 patients, with all seven treated by excision and aggressive local irradiation achieving control.
• Significant local morbidity occurred in four patients with uncontrolled local disease.
• Supraclavicular recurrence correlated with subsequent systemic progression, while inguinal recurrence suggested subsequent abdominal progression.
• Median survival after recurrence was 19 months, but six patients achieved long-term disease-free survival (median follow-up 27 months).

Conclusions:

• Isolated peripheral lymph node recurrence of endometrial carcinoma, though associated with advanced initial disease, can be locally controlled with aggressive treatment.
• Effective systemic adjuvant therapy is needed, but thorough restaging and aggressive local management can offer potential for long-term, disease-free survival.
