Int J Womens Health 2024; 16:401-410. [PMID: 38463686 PMCID: PMC10924845 DOI: 10.2147/ijwh.s450457] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 02/25/2024] [Indexed: 03/12/2024] Open
Abstract
Purpose To determine the disparities in survival outcomes between stage IIB-IVA cervical squamous cell carcinoma (SCC) and adenocarcinoma (AC) treated with chemoradiotherapy. Methods Patients diagnosed between 2004 and 2015 were retrospectively included from the Surveillance, Epidemiology, and End Results databases. Propensity score matching (PSM) was used in this study. The primary endpoints were cervical cancer-specific survival (CCSS) and overall survival (OS). Results A total of 2752 patients were identified, including 87.5% (n=2408) were SCC and 12.5% (n=344) were AC. Patients with AC had inferior 5-year CCSS (67.5% vs 54.8%, P<0.001) and OS (58.4% vs 47.2%, P<0.001) compared to those with the SCC subtype. The hazard curve of cervical cancer-related death in AC peaked at 2 years (19%) and still small peaks in the 7 and 11 years of follow-up. Regarding SCC, cervical cancer-related deaths peaked at 2 years (15%) and the hazard rate was 2.0% during the six years of follow-up. The multivariate Cox regression analyses indicated that histology was an independent prognostic factor associated with survival outcomes. Patients with AC had significantly poor CCSS (P<0.001) and OS (P<0.001). Similar results were found after PSM. Conclusion Our study demonstrates a significantly better prognosis for cervical SCC patients compared to those with cervical AC undergoing chemoradiotherapy. These results highlight the importance of histological subtyping in predicting treatment outcomes and tailoring therapeutic strategies.

Prognostic Factors of Cervical Adenocarcinoma With Positive Pelvic Lymph Node Metastases Without Preoperative Lymph Node Enlargement Treated With Radical Hysterectomy. CANCER DIAGNOSIS & PROGNOSIS 2023; 3:96-101. [PMID: 36632584 PMCID: PMC9801446 DOI: 10.21873/cdp.10185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 10/12/2022] [Indexed: 01/01/2023]
Abstract
BACKGROUND/AIM Pelvic lymph node (LN) metastases are found histopathologically after radical hysterectomy (RH) in some cases of cervical adenocarcinoma with no enlarged LNs on preoperatively. The aim was to clarify whether LN metastasis is a prognostic factor in these patients, and whether any postoperative therapy is advisable. PATIENTS AND METHODS Sixty-one patients with stage I-II cervical adenocarcinoma [International Federation of Obstetrics and Gynecology (FIGO) 2008] with no enlarged pelvic LNs on preoperative imaging evaluation who underwent RH at our institution were retrospectively examined for clinicopathological, treatment, and prognosis-related factors. RESULTS The median age was 47 years. FIGO stages were IB1 in 44 patients, IB2 in 10, IIA in 4, and IIB in 3. Seventeen patients (27.9%) had positive pelvic LNs. The multivariate analysis for both overall (OS) and disease-free (DFS) survival showed only pelvic LN metastasis was an independent prognostic factor. In a multivariate analysis of LN-positive cases, multiple LN metastases was an independent prognostic factor for poorer DFS. OS rates were 100%, 83.3%, and 30.0%, and DFS rates were 85.5%, 83.3%, and 12.5% for patients with no LN metastasis, single metastasis, and multiple metastases, respectively, showing a significant difference. Eight recurrences were observed in 10 patients with multiple node-positive disease, and six (75%) had an intrapelvic recurrence. CONCLUSION Among patients who underwent RH for cervical adenocarcinoma with no preoperative enlarged LN and positive pelvic LNs confirmed postoperatively, multiple positive pelvic LNs are an independent poor prognostic factor. Because pelvic recurrence is common, concurrent chemoradiotherapy, possibly using paclitaxel and cisplatin, should be considered as adjuvant therapy.

Treatment Outcomes of Computer Tomography-Guided Brachytherapy in Cervical Cancer in Hong Kong: A Retrospective Review. Cancers (Basel) 2022; 14:cancers14163934. [PMID: 36010927 PMCID: PMC9406104 DOI: 10.3390/cancers14163934] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 08/11/2022] [Indexed: 11/29/2022] Open
Abstract
Simple Summary This retrospective study reviews 135 patients with locally advanced cervical cancer treated with chemo-radiotherapy with image-guided adaptive brachytherapy with CT guidance. The study has a long follow-up period of 53.6 months. The outcome was excellent with a five-year local control, pelvic control, distant metastasis-free survival and overall survival rates being 90.7%, 84.2%, 80.0% and 87.2%, respectively. Adenocarcinoma was significantly associated with worse local control, pelvic control, distant metastasis-free survival and overall survival rates. Abstract (1) Background: To report the long-term clinical outcomes of computer-tomography (CT)-guided brachytherapy (BT) for locally advanced cervical cancer. (2) Methods: A total of 135 patients with FIGO stage IB-IVA cervical cancer treated with definitive radiotherapy +/− chemotherapy with an IGABT boost at Queen Mary Hospital, Hong Kong, between November 2013 and December 2019 were included. Treatment included pelvic radiotherapy 40 Gy/20 Fr/4 weeks +/− chemotherapy then CT-guided BT (7 Gy × 4 Fr) and a sequential parametrial boost. The primary outcome was local control. Secondary outcomes were pelvic control, distant metastasis-free survival, overall survival (OS) and late toxicities. (3) Results: The median follow-up was 53.6 months (3.0–99.6 months). The five-year local control, pelvic control, distant metastasis-free survival and OS rates were 90.7%, 84.3%, 80.0% and 87.2%, respectively. The incidence of G3/4 long-term toxicities was 6.7%, including proctitis (2.2%), radiation cystitis (1.5%), bowel perforation (0.7%), ureteric stricture (0.7%) and vaginal stenosis and fistula (0.7%). Patients with adenocarcinomas had worse local control (HR 5.82, 95% CI 1.84–18.34, p = 0.003), pelvic control (HR 4.41, 95% CI 1.83–10.60, p = 0.001), distant metastasis-free survival (HR 2.83, 95% CI 1.17–6.84, p = 0.021) and OS (HR 4.38, 95% CI: 1.52–12.67, p = 0.003) rates. Distant metastasis-free survival was associated with HR-CTV volume ≥ 30 cm3 (HR 3.44, 95% CI 1.18–9.42, p = 0.025) and the presence of pelvic lymph node (HR 3.44, 95% CI 1.18–9.42, p = 0.025). OS was better in patients with concurrent chemotherapy (HR 4.33, 95% CI: 1.40–13.33, p = 0.011). (4) Conclusions: CT-guided BT for cervical cancer achieved excellent long-term local control and OS. Adenocarcinoma was associated with worse clinical outcomes. (4) Conclusion: CT-guided BT for cervical cancer achieved excellent long-term local control and OS. Adenocarcinoma was associated with worse clinical outcomes.
