Zhang Z, Zhao H, Cheng G. Long term clinical outcomes of cervical cancer patients who were recommended surgery but did not undergo it: A SEER database study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108572. [PMID: 39121635 DOI: 10.1016/j.ejso.2024.108572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2024] [Revised: 07/19/2024] [Accepted: 07/29/2024] [Indexed: 08/12/2024]
Abstract
BACKGROUND This study analyzed the long-term clinical outcomes of cervical cancer patients recommended surgery but who did not undergo it using the Surveillance, Epidemiology, and End Results (SEER) database. The aim was to identify the subgroups with comparable overall survival (OS) and cancer-specific survival (CSS) through stratified analysis. METHODS Cases of cervical cancer were retrieved from SEER database using SEER*Stat software. This included patients in the non-surgery group (recommended surgery but did not undergo it), and a reference surgery group. Propensity score matching balanced differences between the non-surgery and surgery groups. Stratified analysis and log-rank tests were used to identify subgroups within the non-surgery group with comparable OS and CSS to the surgery group. RESULTS A total of 30,807 cervical cancer patients were included in the OS and CSS analysis. In the matched cohort (n = 1278), patients in the non-surgery group had significantly lower 5-year CSS (63.2 % vs. 80.1 %, P < 0.001) and 5-year OS (59.0 % vs. 78.0 %, P < 0.001). However, within the matched cohort, there was no statistically significant difference in OS and CSS between the non-surgery and surgery groups in subgroups diagnosed during 2010-2014 (P = 0.064, P = 0.182), 2015-2020 (P = 0.122, P = 0.518), T2 stage (P = 0.139, P = 0.052), T3 stage (P = 0.502, P = 0.317), or with distant metastasis (M1) (P = 0.411, P = 0.520). CONCLUSION Patients in the non-surgery group generally exhibited lower long-term clinical outcomes compared to those in the surgery group. However, with advancements in non-surgical treatment techniques, particularly notable in patients with T2, T3, and M1 stages, these differences are gradually diminishing.

Abstract
BACKGROUND/AIM This study aimed to evaluate the outcome of radiation therapy for patients with distant lymph node (LN) metastases, without organ metastases from uterine cervical cancer (UCC). PATIENTS AND METHODS Twenty-six patients with UCC with distant LN metastases received radiotherapy and were retrospectively analyzed. The sites of distant LN metastasis were as follows; Supraclavicular in 19, inguinal in nine, axillary in four, and others in three. The mean dose prescribed for these was 50 (range=40-60) Gy. RESULTS The 2-year overall, cause-specific, and progression-free survival, and local control of primary tumor rates were 51.3%, 51.3%, 46.9%, and 67.9%. In multivariate analysis, performance status ≥1 (p=0.007), para-aortic LN metastases (p=0.001), and lack of high-dose-rate intracavitary brachytherapy (p=0.033) were significantly associated with poor overall survival. Performance status ≥1 (p=0.004), and para-aortic LN metastases (p=0.014) were significantly associated with poor cause-specific survival. CONCLUSION This study demonstrated favorable local control in patients with UCC with distant LN metastases.

Abstract
BACKGROUND/AIM To investigate the role and outcomes of radiation therapy (RT) for stage IVB uterine cervical cancer (UCC) patients with lung (oligo) metastases due to the lack of recent reports on the subject. PATIENTS AND METHODS The cohort for this retrospective study comprised 23 consecutive patients with UCC (squamous cell carcinoma, n=13) and lung metastases who had received pelvic RT. Ten had lung metastases only, including 7 with oligometastases (≤4 lung metastases); the remaining 13 also had other distant metastases. RESULTS Nine (39.1%) of the 22 patients (95.7%) completed RT without interruption. The 1-year primary progression-free rate was 95.2%. The 1-year overall survival rate was 47.2 % (estimated median survival: 9 months). Significant prognostic factors for survival included: i) ≤4 lung metastases (p=0.035), ii) unilateral lung metastases (p=0.039), iii) primary tumor diameter <100 mm (p<0.001), and iv) ECOG performance status <1 (p=0.015). CONCLUSION RT is safe and effective for stage IVB UCC patients with lung metastases.

[PMID: 32047560 PMCID: PMC6995375 DOI: 10.7150/jca.37390] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Accepted: 12/01/2019] [Indexed: 01/12/2023] Open
Abstract
Background: Uterine cervical cancer (UCC) is a common malignant tumor in women. We conducted this work to provide a though description on the patterns of distant metastases and to investigate the relevant factors for prognosis of UCC patients based on a large population. Patients and methods: UCC patients with FIGO stage IVB, being the study group, were identified from the Surveillance, Epidemiology, and End Result (SEER) database from 2010 to 2016. UCC patients with same inclusion criteria, being validation group, were identified from Tianjin First Central Hospital from 2004 to 2017. Patterns of distant metastases were described according to the number of metastatic sites. Survival of different patterns were calculated and prognostic factors were investigated by Cox hazard regression analysis. Results: Distant metastases were recorded in 1448 UCC patients among whom 295 patients (30.8%) developed metastases in two or more organs. Compared with the median OS of 8 (95%CI, 7.07-8.93) months in the patients with the single site, worse survival of 5 (95%CI, 4.29-5.71) months was noticed in the patients with multiple metastases. Age ≥ 65 years, black race, higher grade, higher T stage and more metastatic sites were proved to be the prognostic factors for all the patients in the advanced stage and the results were partly validated in the validation cohort. Moreover, black race and higher T-stage for the patients with the single metastatic sites and age ≥ 65, uninsured status, surgical treatment and metastatic pattern for the patients with two metastatic sites were prognostic factors. No independent factor was found in patients with three or more metastases. Conclusion: Around 70% of the patients suffered one site distant metastasis in UCC patients with IVB stage while 30% with multiple metastases and a significantly reduced survival. Different survivals and prognostic factors were noticed for different patterns of distant metastases.

Abstract
Background: Metastatic cervical cancer (mCEC) is the end stage of cervical cancer. This study aimed to establish and validate a nomogram to predict the overall survival (OS) of mCEC patients. Methods: We investigated the Surveillance, Epidemiology, and End Results (SEER) database for mCEC patients diagnosed between 2010 and 2014. Univariate and multivariable Cox analyses was performed to select the clinically important predictors of OS when developing the nomogram. The performance of nomogram was validated with Harrell's concordance index (C-index), calibration curves, receiver operating characteristic curve (ROC), and decision curve analysis (DCA). Results: One thousand two hundred and fifty-two mCEC patients were included and were divided into training (n = 880) and independent validation (n = 372) cohorts. Age, race, pathological type, histology grade, radiotherapy, and chemotherapy were independent predictors of OS and used to develop the nomogram for predicting 1- and 3-year OS. This nomogram had a C-index of 0.753 (95% confidence interval [CI]: 0.780-0.726) and 0.751 (95% CI: 0.794-0.708) in the training and the validation cohorts, respectively. Internal and external calibration curves indicated satisfactory agreement between nomogram prediction and actual survival, and DCA indicated its clinical usefulness. Furthermore, a risk stratification system was established that was able to accurately stratify mCEC patients into three risk subgroups with significantly different prognosis. Conclusions: We constructed the first nomogram and corresponding risk classification system to predict the OS of mCEC patients. These tools showed satisfactory accuracy, and clinical utility, and could aid in patient counseling and individualized clinical decision-making.

Radiotherapy Improves the Survival of Patients With Metastatic Cervical Cancer: A Propensity-Matched Analysis of SEER Database. Int J Gynecol Cancer 2019; 28:1360-1368. [PMID: 30036221 DOI: 10.1097/igc.0000000000001313] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/25/2022] Open
Abstract
OBJECTIVE To demonstrate whether radiotherapy has an effect on the survival of patients with stage IVb (M1) cervical cancer, as it has not been adequately clarified. METHODS We analyzed International Federation of Gynecology and Obstetrics (FIGO) stage M1 cervical cancer diagnosed in patients between 1992 and 2013 using population-based data from the Surveillance, Epidemiology, and End Results registry. Propensity score (PS) analysis with 1:1 matching and the nearest neighbor matching method was performed to ensure well-balanced characteristics of comparison groups. Data were analyzed by Kaplan-Meier and Cox proportional hazards regression models to evaluate the overall survival (OS) and cancer-specific survival (CSS) months with corresponding 95% confidence intervals (95% CIs). RESULTS In general, receiving radiotherapy significantly improved OS and CSS both before and after PS matching (PSM) (P < 0.001), with significantly improved OS (hazard ratio, 0.69; 95% CI, 0.62-0.76) and CSS (hazard ratio, 0.79; 95% CI, 0.70-0.89) after PSM in patients with stage M1 cervical cancer. Before PSM, radiotherapy was found to be associated with improved survival even for the patients with stage M1 cervical cancer with extensive metastasis (≥2 metastatic sites) (P < 0.001). Although P value was not significant for brain metastasis, the survival month was numerically improved before PSM (OS and CSS, 1 month vs 4 months). Overall, radiotherapy still significantly improved survival for patients with one metastatic site (ie, oligometastases) either before or after PSM (P < 0.05), with the survival month improved more than 6 months. CONCLUSIONS The large Surveillance, Epidemiology, and End Results results support that radiotherapy might improve the survival of patients with metastatic cervical cancer. It might be prudent to carefully select suitable patients for radiation therapy for metastatic cervical cancer.

Abstract
As the average lifespan lengthens worldwide, and the older adult population increases, the number of elderly patients with uterine cervical cancer is increasing. Because intensive and invasive treatments, including surgery, are frequently unacceptable in elderly patients, cancer treatments for these patients must be carefully considered. Elderly patients have undergone radiation therapy as less-invasive curative treatment, and it has been shown to be safe and effective for local control of cervical cancer in this population, even among patients aged ≥80 years treated with curative radiation doses. Although concurrent chemoradiotherapy is the standard treatment for locally advanced cervical cancer, it is unclear whether the addition of chemotherapy to radiation therapy prolongs survival in elderly patients. Elderly patients treated with curative radiation therapy for cervical cancer might develop more therapy-related gastrointestinal and hematological toxicities and insufficiency fractures compared with younger patients. However, advanced techniques of radiation therapy (eg, intensity-modulated radiation therapy and volumetric modulated arc therapy with photons, charged-particle radiation therapy with protons and carbon ions in external-beam radiation therapy, and image-guided adaptive brachytherapy) can minimize radiation-induced toxicities and thus make curative treatment safer and more effective for elderly patients with uterine cervical cancer.
