ObjectiveWe investigated whether the pretreatment albumin to globulin ratio, serum albumin level, and serum globulin level can be used to predict survival among cervical cancer patients treated with radiation based therapy and assessed globulin fractions.MethodsWe retrospectively enrolled 128 patients with cervical cancer treated with radiation based therapy at our institution between 2010 and 2015. The associations of the pretreatment albumin to globulin ratio, and serum albumin and globulin levels with overall survival were assessed. Additionally, the associations of the globulin fractions with the serum globulin levels and overall survival were evaluated.ResultsMedian follow-up duration was 30 months (IQR 16–44 months). A low albumin to globulin ratio (< 1.53) was found to be an independent prognostic factor for overall survival (HR= 3.07; 95% CI, 1.03 to 13.3; P=0.044). On evaluating serum globulin and albumin separately, a high serum globulin level was significantly associated with overall survival (cut-off value 2.9 g/dL; HR=3.74; 95% CI 1.08 to 23.6; P=0.036) whereas a low serum albumin level was not associated with overall survival (cut-off value 3.6 g/dL; HR=1.77; 95% CI 0.57 to 4.54; P=0.29). Electrophoresis data of the serum proteins revealed that the γ-globulin fraction was most strongly correlated with the globulin levels (P<0.001). Furthermore, a high γ-globulin level (≥1.28 g/dL) was significantly associated with poor overall survival (log rank test, P=0.034).ConclusionsA pretreatment low albumin to globulin ratio, which might be attributable to a high serum globulin level, can be used to predict poor prognosis in cervical cancer patients treated with radiation based therapy.

Aim: We compared the short-term outcomes between conventional laparoscopic surgery (CLS) and robotassisted surgery (RAS) to assess the technical feasibility of the latter for early-stage endometrial cancer. Methods: We retrospectively compared the perioperative outcomes between two groups of 223 patients (CLS group, n = 102; RAS group, n = 121) with early-stage endometrial cancer. Surgical procedures included hysterectomy, bilateral salpingo-oophorectomy and retroperitoneal lymphadenectomy. We analyzed the data from intrapelvic surgery alone because para-aortic lymphadenectomy was performed via conventional endoscopic extraperitoneal approach without robot for both groups. Results: No differences were identified in patients' age and body mass index. The mean operative time was 133 AE 28 versus 178 AE 41 min (P < 0.01), mean blood loss was 196 AE 153 versus 237 AE 146 mL (P = 0.047), mean length of postoperative hospital stay was 9 AE 4 versus 8 AE 3 days (P = 0.01) and mean rate of perioperative complications of Clavien-Dindo grade III or higher was 2.0 versus 3.4% (P = 0.53) for the CLS versus RAS groups, respectively. There was no significant difference in the number of resected lymph nodes. Conclusion:The operative time was significantly longer and blood loss was significantly greater in the RAS group than in the CLS group, without a significant difference in the number of resected lymph nodes. These differences are within an acceptable clinical range, showing that RAS is feasible and safe for early-stage endometrial cancer, providing short-term outcomes comparable to those of conventional surgery. Future studies are warranted to compare the long-term oncological outcomes by extending the observation period and including para-aortic lymphadenectomy data.

Aim Patients with recurrent cervical cancer after radiotherapy have poor prognoses because of the lack of effective treatment options. Biomarkers to predict survival outcomes for recurrent cervical cancer are warranted because patients with limited life expectancy sometimes benefit from less aggressive treatment in combination with early palliative care. Therefore, we aimed to explore a predictive biomarker for the outcomes of patients with recurrent cervical cancer. Methods We retrospectively investigated 231 patients initially treated with radiation‐based therapy between January 2004 and December 2015. The associations between clinicopathological features at the time of relapse and overall survival after relapse were assessed. As factors which reflect patients' conditions, we particularly focused on C‐reactive protein‐to‐albumin ratio (CAR) and neutrophil‐to‐lymphocyte ratio (NLR) at the time of relapse. Additionally, we investigated biomarkers predictive of short‐term survival. Results Among 231 patients, 91 patients experienced relapse and 74 patients died during the follow‐up period. Multivariate analysis revealed that treatment after relapse, CAR, and NLR was significantly associated with overall survival. Among them, treatment after relapse significantly affected survival outcomes, and patients who received definitive local treatment had a better 3‐year survival rate than those who received other treatments. Conversely, NLR was the most influential biomarker for short‐term survival, and the prognosis of patients with high NLRs was much worse than those with low NLRs. Conclusions This study thus demonstrated that, for the patients with recurrent cervical cancer who received radiation‐based therapy, definitive local treatment can provide long‐term survival and extremely high NLRs are predictive of short‐term survival.
