Locally Advanced Cervical Cancer

We present our results of 3D CT/MRI brachytherapy (BT) planning in 115 patients with locally advanced cervical cancer T2b-3bN0-1M0. The aim of this study was to assess the differences in the visualization of tumor target volumes and risk organs during the 3D CT/MRI BT. The results of the study revealed that the use of MRI imaging for dosimetric planning of dose distribution for a given volume of a cervical tumor target was the best method of visualization of the soft tissue component of the tumor process in comparison with CT images, it allowed to differentially visualize the cervix and uterine body, directly the tumor volume. Mean D90 HR-CTV for MRI was 32.9 cm3 versus 45.9 cm3 for CT at the time of first BT, p = 0.0002, which is important for local control of the tumor process. The contouring of the organs of risk (bladder and rectum) through MRI images allows for more clearly visualizing the contours, which statistically significantly reduces the dose load for individual dosimetric planning in the D2cc control volume, і.є. the minimum dose of 2 cm3 of the organ of risk: D2cc for the bladder was 24.3 Gy for MRI versus 34.8 Gy on CT (p = 0.045); D2cc for the rectum - 18.7 Gy for MRI versus 26.8 Gy for CT (p = 0.046). This is a prognostically important stage in promising local control, which allows preventing manifestation of radiation damage.

Response To Neoadjuvant Chemotherapy

PURPOSE The aim of the study was to investigate the role of squamous cell carcinoma antigen (SCC) in the management of patients with locally advanced cervical cancer treated by neoadjuvant chemotherapy and radical surgery. PATIENTS AND METHODS SCC assay was performed with a radioimmunoassay kit in a series of 102 patients with locally advanced cervical cancer. The values of 2.5, 5, and 7 ng/mL were used to define SCC antigen positivity. The chi 2 and Fisher's exact test and the stepwise logistic regression were used to evaluate the distribution of marker values. Analysis of survival was performed using the Kaplan and Meier test and Cox multivariate regression analysis. RESULTS SCC levels were elevated in 65%, 45%, and 32% of patients with primary tumors for cutoff values of 2.5, 5, and 7 ng/mL, respectively. SCC pretreatment levels correlated with stage, tumor volume and lymph node status. In the multivariate analysis, SCC expression proved to be an independent predictor of response to neoadjuvant chemotherapy. SCC posttreatment levels were strongly related to chemotherapy response. Moreover, the overall correlation between the clinical course of the disease and the variation of SCC levels was 83%. In patients with squamous cell tumors, survival was significantly longer in SCC-negative cases compared with SCC-positive cases (P = .04). Moreover, in patients undergoing surgery after response to neoadjuvant chemotherapy, low SCC values were associated with better prognosis (P = .02). In the multivariate analysis, parametrial involvement and SCC status proved to retain an independent prognostic value. CONCLUSION Our data show that SCC assay may provide useful information to improve the prognostic characterization and disease monitoring of patients with locally advanced cervical cancer undergoing neoadjuvant chemotherapy.
