The best postoperative adjuvant therapy for patients with early stage cervical adenosquamous carcinoma

Abstract

Background Cervical adenosquamous carcinoma (ASC) was previously thought to be a subtype of cervical adenocarcinoma, but recent studies have found that the clinical features of the two diseases are different. Moreover, the pathological characteristics, survival, prognosis, and optimal ASC therapy remain unknown. This study aims to retrospectively analyze the postoperative survival of patients with early-stage ASC and to evaluate their condition after treatment with postoperative concurrent chemoradiotherapy (CCRT) and prophylactic irradiation of the para-aortic lymphatic drainage area. Methods This study enrolled 131 patients with pathologically confirmed ASC screened from 3502 patients with confirmed stage I–II cervical cancer diagnosis who had completed surgical treatments in our hospital. Among the 131 enrolled patients, 75 patients received CCRT, 33 patients received chemotherapy (CT), and 23 patients did not receive adjuvant treatment (named surgery alone (S alone). Of the 75 patients CCRT, 43 patients received prophylactic irradiation of the para-aortic lymphatic drainage area. The efficacy of the postoperative treatments of patients among groups (CCRT, CT, and S alone) was compared. Results The median follow-up time, age, and overall survival (OS) were 76 months, 43 years, and 74 months, respectively. The 3- and 5-year survival rates were 82% and 71.4%, respectively. The median disease-free survival (DFS) was 64 months. Cox regression analysis showed that postoperative adjuvant treatment modalities and positive lymph node metastases were associated with OS and DFS. Patients who received CCRT treatment had higher OS and DFS than those with CT and S alone. Prophylactic irradiation of the para-aortic lymphatic drainage area did not improve the OS and DFS of patients with CCRT treatment. However, further subgroup analysis suggested that it might improve survival rates in patients who had positive pelvic lymph nodes as confirmed by postoperative pathology. Conclusion Postoperative CCRT improved the survival rates in patients with early-stage ASC. The value of prophylactic irradiation of the para-aortic lymphatic drainage area remains debatable, but it may benefit patients with pelvic lymph node involvement.

“…It might owe to the early diagnosis and comprehensive adjuvant treatment of married patients [30,31]. For adjuvant treatment, some studies showed that chemotherapy was beneficial to prognosis [32], while others reported that postoperative radiotherapy could improve the survival rate of patients with early cervical cancer [33]. Our study found that patients receiving postoperative radiotherapy have better CSS, which needs more confirmation studies.…”

“…A significant number of studies examining the role of adjuvant therapy in early stage cervical cancer were conducted according to the FIGO 2009 staging criteria and included lymph node positive patients. [14][15][16] The patients in our study were staged according to the current FIGO staging system, which was revised in 2018 and included pelvic/paraaortic lymph node involvement in the staging. Therefore, it does not include lymph node positive patients.…”
