Postoperative adjuvant chemotherapy for node-positive cervical adenocarcinoma

Area of Science:

• Gynecologic Oncology
• Medical Oncology
• Cancer Research

Background:

• Cervical adenocarcinoma is a rare subtype of cervical cancer.
• Node-positive status in cervical cancer indicates a higher risk of recurrence and poorer prognosis.
• The role of adjuvant chemotherapy in node-positive cervical adenocarcinoma remains to be fully elucidated.

Purpose of the Study:

• To evaluate the efficacy of postoperative adjuvant chemotherapy in patients with node-positive cervical adenocarcinoma.
• To assess recurrence patterns and survival outcomes following surgical treatment and chemotherapy.

Main Methods:

• Retrospective analysis of 98 patients with clinical stage I and II cervical adenocarcinoma treated surgically between 1994 and 2002.
• Surgical procedures included radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy.
• Twenty-one node-positive patients received postoperative chemotherapy without radiotherapy, followed for at least 5 years.

Main Results:

• Nine of 21 node-positive patients (43%) experienced recurrence, with all 9 succumbing to the disease.
• Extrapelvic lesions accounted for 6 of the 9 recurrences.
• Five-year disease-free survival was 57%, and overall survival was 67%.
• Recurrence risk was higher in patients with 6 or more positive nodes compared to those with fewer than 3.

Conclusions:

• Postoperative chemotherapy may play a role in managing node-positive cervical adenocarcinoma, but its effectiveness appears limited.
• Chemotherapy alone may not be as effective as in squamous cell carcinoma.
• Recurrence predominantly occurred at distant sites, even without pelvic radiation, highlighting the need for systemic treatment strategies.
