Objective
To compare response rate and survivals of locally advanced stage cervical cancer patients who had standard concurrent chemoradiation therapy (CCRT) alone to those who had adjuvant chemotherapy (ACT) after CCRT.
Methods
Patients aged 18–70 years who had International Federation of Gynecology and Obstetrics stage IIB–IVA without para-aortic lymph node enlargement, Eastern Cooperative Oncology Group scores 0–2, and non-aggressive histopathology were randomized to have CCRT with weekly cisplatin followed by observation (arm A) or by ACT with paclitaxel plus carboplatin every 4 weeks for 3 cycles (arm B).
Results
Data analysis of 259 patients showed no significant difference in complete responses at 4 months after treatment between arm A (n=129) and arm B (n=130): 94.1% vs. 87.0% (p=0.154) respectively. With the median follow-up of 27.4 months, 15.5% of patients in arm A and 10.8% in arm B experienced recurrences (p=0.123). There were no significant differences of overall or loco-regional failure. However, systemic recurrences were significantly lower in arm B than arm A: 5.4% vs. 10.1% (p=0.029). The 3-year progression-free survival (PFS) and 3-year overall survival (OS) of the patients in both arms were not significantly different. The hazard ratio of PFS and OS of arm B compared to arm A were 1.26 (95% CI=0.82–1.96; p=0.293) and 1.42 (95% CI=0.81–2.49; p=0.221) respectively.
Conclusions
ACT with paclitaxel plus carboplatin after CCRT did not improve response rate and survival compared to CCRT alone. Only significant decrease of systemic recurrences with ACT was observed, but not overall or loco-regional failure.

This study aimed to evaluate the prognostic value of ABO blood groups in early-stage cervical cancer patients. The cohort included 413 patients diagnosed with stages IA2-IB1 cervical cancer who received a radical hysterectomy between 2002 and 2014. The 5-year recurrence-free survival (RFS) and overall survival (OS) were 93.13 and 96.81 % for blood group O, 87.68 and 88.22 % for blood group A, 81.66 and 89.40 % for blood group B, and 83.12 and 94.12 % for blood group AB groups, respectively. Patients were stratified for analysis as either blood group O or non-O. The 5-year RFS and OS were 93.13 and 96.81 % for blood group O and 83.66 and 89.76 % for blood group non-O, respectively. In multivariate analysis, age (P = 0.025), histology (P = 0.020), and deep stromal invasion (P = 0.006) were independent adverse prognostic factors for RFS, while the statistically significant independent prognostic factors for OS were age (P = 0.007) and parametrial involvement (P < 0.001). The Cox model did not show any significant effects of non-O blood group on survival outcome. However, a time-varying-effect Cox model revealed that the non-O blood group was associated with a worse RFS (hazard ratio (HR) 2.69, 95 % confidence interval (95%CI) 1.12-6.46, P = 0.017) and OS (HR 3.13, 95%CI 0.88-11.16, P = 0.053) during the first 5 years. These findings suggest that early-stage cervical cancer patients with a non-O blood group have poorer RFS than the O blood group, which is evidence during the first 5 years.
Objectives: To evaluate sites of failure and long-term survival outcomes of locally advanced stage cervical cancer patients who had standard concurrent chemo-radiation (CCRT) versus those along with adjuvant chemotherapy (ACT) after CCRT. Methods: Patients aged 18-70 years who had FIGO stage IIB-IVA without para-aortic lymph node enlargement (excluding by International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IIIC2r), The Eastern Cooperative Oncology Group (ECOG) scores 0-2, and non-aggressive histopathology were randomized to have CCRT with weekly cisplatin followed by observation (arm A) or ACT with paclitaxel plus carboplatin every 4 weeks for 3 cycles (arm B). Results: From 2015-2017, 259 patients were evaluated. The majority of patients were in stage II and had squamous cell carcinoma with a median tumor size of 5 cm. After the median follow-up of 40.87 months, 17.1% of the patients in arm A and 12.3% of the patients in arm B experienced recurrences (p=0.280). Adding all events of failure (persistence/progression/recurrence), treatment failures tended to be lower in arm A than in arm B: 13.2 versus 21.5 % for loco-regional failure (p = 0.076) and 3.9 versus 6.9% for loco-regional failure and systemic failure (p = 0.278). On the other hand, systemic failure tended to be higher in arm A than in arm B: 13.2% versus 6.9% (p =0.094). The 5-year progression-free survival and 5-year overall survival of patients in both arms were not significantly different. Conclusions: ACT with paclitaxel plus carboplatin after CCRT did not improve response or survival of patients compared to CCRT alone. Although systemic failure tended to be lower in patients who had ACT after CCRT than those who had only CCRT, loco-regional failure with or without systemic failure tended to be higher. However, all of these differences were not statistically significant.
