The predictive value of measurement of SUVmax and SCC-antigen in patients with pretreatment of primary squamous cell carcinoma of cervix.

Use of positron emission tomography/computed tomography (PET/CT) and serum squamous cell carcinoma (SCC) antigen (SCC-ag) as predictors for poor prognosis of pretreatment of primary SCC of cervix. The distribution of cases that scored positive for each of the biological parameters examined was correlated with maximum SUV (SUVmax) of PET/CT and serum SCC-ag for 52 participants prior to radiotherapy (RT) with or without concurrent chemotherapy (CCRT) with pretreatment of primary SCC of cervix. There were significant correlations between the SUVmax of the primary tumor and tumor maximum size (P=0.027), and the lymph node metastasis (P=0.039). The serum SCC-ag had a statistically significant association with the clinicopathological parameters such as FIGO stage (P=0.045) and tumor maximum size (P=0.008), although there was no correlation noted between the SUVmax of the primary tumor and the serum SCC-ag (R=0.155). The high SUVmax of the primary tumor (≥ 15.6) plus lymph node metastasis (a short-axis diameter of over 10mm with a SUVmax ≥ 3.5) were significant predictors for poor prognosis when compared with the low SUVmax of the primary tumor (<15.6) or the high SUVmax of the primary tumor plus negative lymph node metastasis (a short-axis diameter of under 10mm or SUVmax <3.5) (overall survival rate; P=0.0211). The present findings indicate that the high SUVmax of the primary tumor plus lymph node metastasis with pretreatment of primary SCC of cervix may be associated with a poor prognosis.

Prognostic utility of squamous cell carcinoma antigen in carcinoma of the cervix: association with pre- and posttreatment FDG-PET.

Squamous cell carcinoma antigen (SCC Ag) is a serum biomarker for squamous cell carcinoma (SCC) of the cervix. We investigated the prognostic significance of SCC Ag levels before and at the completion of chemoradiotherapy and compared these levels with the results of pre- and posttreatment positron emission tomography/computed tomography (PET/CT) using [(18)F]fluorodeoxyglucose (FDG). The records of 63 women who underwent definitive chemoradiotherapy for SCC of the cervix were reviewed. SCC Ag levels were obtained before and at the completion of radiotherapy. Patients were divided into two groups on the basis of their pretreatment SCC Ag level (>30 ng/mL vs. ≤30 ng/mL). Pre- and posttreatment FDG-PET/CT characteristics and progression-free survival (PFS) were analyzed according to SCC Ag groups. Median follow-up was 12 months. Women with SCC Ag >30 ng/mL at diagnosis had more advanced lymph node disease on pretreatment FDG-PET/CT than those with SCC Ag ≤30 ng/mL (p = .002). Women whose SCC Ag normalized at the completion of chemoradiotherapy were more likely to have a complete metabolic response on their 3-month posttreatment FDG-PET/CT than those whose SCC Ag did not normalize (p = .006). The 2-year PFS was 73% for patients with a SCC Ag level ≤30 ng/mL at diagnosis compared with 0% for those with a SCC Ag level >30 ng/mL at diagnosis (p < .0001). The 2-year PFS was 62% for patients whose SCC Ag normalized at the completion of chemoradiotherapy compared with 0% for those whose SCC Ag did not normalize (p = .0004). Elevated SCC Ag at diagnosis and failure of the SCC Ag to normalize at the completion of treatment are associated with incomplete metabolic response and decreased PFS.

Association of pretreatment SUV(max) of cervix and SCC-antigen with FIGO2018 stage in Stage IIB-IVB squamous cervical cancer and relationship to prognosis.

To evaluate the association of pretreatment maximum standardized 18 F-fluorodeoxyglucose uptake value (SUVmax ) of cervix and serum squamous cell carcinoma antigen (SCC-ag) with FIGO2018 stage and prognosis among women with Stage IIB-IVB squamous cervical cancer. Retrospective study of 116 women with FIGO2018 Stage IIB-IVB cervical cancer treated in Hangzhou, China, 2013-2015. The relationship between pretreatment SUVmax or SCC-ag and prognostic factors was evaluated by univariate and multivariate analyses. Women were stratified by mean SUVmax and mean SCC-ag. There was a significant difference between low (<12.9) and high (≥12.9) SUVmax groups in menopause (P = 0.004), FIGO2018 stage (P = 0.015), and survival rate (P < 0.001). The low group had better overall and progress-free survival by Kaplan-Meier evaluation (both P = 0.022). High SCC-ag (≥14.6 ng/mL) was associated with FIGO2018 stage (P = 0.038) and distant metastasis (P = 0.011). There was a significant correlation between SUVmax and serum SCC-ag (P = 0.026). In multivariate Cox regression analyses, FIGO2018 stage (P = 0.019) and SUVmax of cervix (P = 0.015) were independent predictors of poor outcome in squamous cervical cancer. Both SUVmax of cervix and SCC-ag were associated with FIGO2018 stage in squamous cervical cancer. Pretreatment high SUVmax of cervix and advanced FIGO2018 stage might indicate a poor prognosis.
