Objective: There is no consensus on whether platinum doublet chemotherapy or lenvatinib and pembrolizumab (LEN/PEM) is superior for advanced or recurrent endometrial cancer. Thus, this study aimed to compare the prognosis and adverse events in patients with advanced or recurrent endometrial cancer treated with platinum doublet chemotherapy or LEN/PEM. Methods: We retrospectively reviewed the medical records of patients who received platinum doublet chemotherapy or LEN/PEM at our institution for advanced or recurrent endometrial cancer and had a history of platinum-based chemotherapy between January 2013 and August 2023. Results: During the study period, 11 regimens were identified in the platinum doublet chemotherapy group, and 11 regimens were identified in the LEN/PEM group. The objective response rates of the platinum doublet chemotherapy and LEN/ PEM groups were 36.4% and 54.5% (P=0.67), respectively. The 6-month progression-free survival (PFS) rates of the platinum doublet chemotherapy and LEN/PEM groups were 27.3% (95% confidence interval [CI], 13.8%-40.7%) and 70.0% (95% CI, 55.5%-84.5%), respectively. The differences were significant between the two groups. Multivariate analyses of histology, prior lines of chemotherapy, platinum-free intervals, and regimens revealed that the LEN/PEM group had significantly better PFS rates. Conclusion Treatment with LEN/PEM resulted in significantly longer PFS than that of treatment with platinum doublet chemotherapy in patients with advanced and recurrent endometrial cancer. However, further large-scale studies are required to validate these findings.

Purpose: This study was performed to evaluate the prognostic value of preoperative C-reactive protein to albumin ratio (CAR) in older patients with colorectal cancer (CRC) undergoing curative resection. Methods: We retrospectively analyzed 244 older patients (aged 75 years or higher) with pathological stage II or III CRC who underwent curative surgery between 2008 and 2016. The optimal value of CAR was calculated and its correlation with the clinicopathological factors and prognosis was examined. Results: The optimal cutoff value of the CAR was 0.085. High preoperative CAR was significantly associated with high carcinoembryonic antigen levels (P=0.001), larger tumor size (P<0.001), and pT factor (P=0.001). On multivariate analysis, high CAR was independent prognostic factor for relapse-free survival (P=0.042) and overall survival (P=0.001). Conclusion Preoperative elevated CAR could be considered as an adverse predictor of both relapse-free survival and overall survival in older patients with CRC undergoing curative surgery.

Background: and Purpose To assess the long-term outcomes of intracranial dural arteriovenous fistula (DAVF) treated with stereotactic radiosurgery (SRS) alone or embolization and SRS (Emb-SRS) and to develop a grading system for predicting DAVF obliteration. Methods: This multi-institutional retrospective study included 200 patients with DAVF treated with SRS or Emb-SRS. We investigated the long-term obliteration rate and obliteration-associated factors. We developed a new grading system to estimate the obliteration rate. Additionally, we compared the outcomes of SRS and Emb-SRS by using propensity score matching. Results: The 3- and 4-year obliteration rates were 66.3% and 78.8%, respectively. The post-SRS hemorrhage rate was 2%. In the matched cohort, the SRS and Emb-SRS groups did not differ in the rates of obliteration (P=0.54) or post-SRS hemorrhage (P=0.50). In multivariable analysis, DAVF location and cortical venous reflux (CVR) were independently associated with obliteration. The new grading system assigned 2, 1, and 0 points to DAVFs in the anterior skull base or middle fossa, DAVFs with CVR or DAVFs in the superior sagittal sinus or tentorium, and DAVFs without these factors, respectively. Using the total points, patients were stratified into the highest (0 points), intermediate (1 point), or lowest (≥2 points) obliteration rate groups that exhibited 4-year obliteration rates of 94.4%, 71.3%, and 60.4%, respectively (P<0.01). Conclusions SRS-based therapy achieved DAVF obliteration in more than three-quarters of the patients at 4 years of age. Our grading system can stratify the obliteration rate and may guide physicians in treatment selection.

Prostate cancer is one of the most common cancers in men. Choline PET or PET/CT has been used to visualize prostate cancer, and high levels of choline accumulation have been observed in tumors. However, the uptake system for choline and the functional expression of choline transporters in prostate cancer are not completely understood. In this study, the molecular and functional aspects of choline uptake were investigated in the LNCaP prostate cancer cell line along with the correlations between choline uptake and cell viability in drug-treated cells. Choline transporter-like protein 1 (CTL1) and CTL2 mRNA were highly expressed in LNCaP cells. CTL1 and CTL2 were located in the plasma membrane and mitochondria, respectively. [3H]Choline uptake was mediated by a single Na+-independent, intermediate-affinity transport system in the LNCaP cells. The anticancer drugs, flutamide and bicalutamide, inhibited cell viability and [3H]choline uptake in a concentration-dependent manner. The correlations between the effects of these drugs on cell viability and [3H]choline uptake were significant. Caspase-3/7 activity was significantly increased by both flutamide and bicalutamide. Furthermore, these drugs decreased CTL1 expression in the prostate cancer cell line. These results suggest that CTL1 is functionally expressed in prostate cancer cells and are also involved in abnormal proliferation. Identification of this CTL1-mediated choline transport system in prostate cancer cells provides a potential new therapeutic target for the treatment of this disease.

In this study, we examined the molecular and functional characterization of choline uptake in the human esophageal cancer cells. In addition, we examined the influence of various drugs on the transport of [3H]choline, and explored the possible correlation between the inhibition of choline uptake and apoptotic cell death. We found that both choline transporter-like protein 1 (CTL1) and CTL2 mRNAs and proteins were highly expressed in esophageal cancer cell lines (KYSE series). CTL1 and CTL2 were located in the plasma membrane and mitochondria, respectively. Choline uptake was saturable and mediated by a single transport system, which is both Na+-independent and pH-dependent. Choline uptake and cell viability were inhibited by various cationic drugs. Furthermore, a correlation analysis of the potencies of 47 drugs for the inhibition of choline uptake and cell viability showed a strong correlation. Choline uptake inhibitors and choline deficiency each inhibited cell viability and increased caspase-3/7 activity. We conclude that extracellular choline is mainly transported via a CTL1. The functional inhibition of CTL1 by cationic drugs could promote apoptotic cell death. Furthermore, CTL2 may be involved in choline uptake in mitochondria, which is the rate-limiting step in S-adenosylmethionine (SAM) synthesis and DNA methylation. Identification of this CTL1- and CTL2-mediated choline transport system provides a potential new target for esophageal cancer therapy.
