Objective:
To identify a relatively high-risk population in postoperative intermediate-risk cervical cancer and evaluate the effect of platinum-based adjuvant chemotherapy (CT).
Methods:
We retrospectively reviewed the medical records of patients with stage IA2-IIA cervical cancer who had been treated with radical hysterectomy and pelvic lymphadenectomy and classified as the intermediate-risk group for recurrence by postoperative pathological examination from January 2007 to December 2018 at 3 medical centers in Japan. First, patients with intermediate-risk were stratified by histological type and the number of intermediaterisk factors (IRF; large tumor diameter, lymph vascular space invasion, and deep cervical stromal invasion) and then divided into 2 groups: high and low-risk population (estimated 5-year recurrence-free survival [RFS] rate with no further therapy [NFT] <90% and ≥90%, respectively). Second, the efficacy of CT for the high-risk population was evaluated by comparing RFS and overall survival (OS) between the patients receiving CT and those with NFT.
Results:
In total, 133 patients were included in the analysis. Among patients with squamous cell carcinoma (SCC) with all IRF or those with non-SCC with 2 to 3 IRF, the 5-year estimated RFS was <90% when treated with NFT. In this population, adjuvant CT was significantly superior to NFT regarding RFS (log-rank, p=0.014), although there was no statistical difference in OS.
Conclusion
Patients with SCC with all 3 IRFs and those with non-SCC with 2 to 3 IRFs were at high risk for recurrence. Adjuvant CT is a valid treatment option for these populations.

A 73-year-old man had been followed up in our hospital after surgery for mitral regurgitation. At the age of 67, he underwent mitral valve plasty through a right mini-thoracotomy approach for atrial functional mitral regurgitation at our hospital. The mean trans-mitral pressure gradient was 5 mmHg after surgery but no heart failure symptoms were observed. At the age of 72, he began to notice fatigue during exertion. Transthoracic echocardiography revealed that the mitral valve regurgitation was controlled to a trace level, but the mean trans-mitral pressure gradient increased to 10 mmHg. Transesophageal echocardiography and contrast-enhanced cardiac computed tomography revealed the restricted opening of the mitral valve and pannus formation around the prosthetic ring. We thus diagnosed mitral stenosis due to pannus overgrowth. He underwent pannus excision and removal of the artificial ring. Postoperative echocardiography revealed that the mean trans-mitral pressure gradient was reduced to 3 mmHg and no residual mitral regurgitation was observed. He was discharged on postoperative day 11 with no major symptoms. He was in New York Heart Association functional class I at 1 year after the surgery and continues to be an outpatient.

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.

Objective:
The purposes of this trial were to demonstrate the feasibility and effectiveness of the hybrid of intracavitary and interstitial brachytherapy (HBT) for locally advanced cervical cancer patients in the phase I/II prospective clinical trial.
Methods:
Patients with FIGO stage IB2-IVA uterine cervical cancer pretreatment width of which was ≥5 cm measured by magnetic resonance imaging were eligible for this clinical trial. The protocol therapy included 30–30.6 Gy in 15–17 fractions of whole pelvic radiotherapy concurrent with weekly CDDP, followed by 24 Gy in 4 fractions of HBT and pelvic radiotherapy with a central shield up to 50–50.4 Gy in 25–28 fractions. The primary endpoint of phase II part was 2-year pelvic progression-free survival (PPFS) rate higher than historical control of 64%.
Results:
Between October 2015 and October 2019, 73 patients were enrolled in the initial registration and 52 patients proceeded to the secondary registration. With the median follow-up period of 37.3 months (range, 13.9–52.9 months), the 2- PPFS was 80.7% (90% confidence interval [CI]=69.7%–88%). Because the lower range of 90% CI of 2-year PPFS was 69.7%, which was higher than the historical control ICBT data of 64%, therefore, the primary endpoint of this study was met.
Conclusion
The effectiveness of HBT were demonstrated by a prospective clinical study. Because the dose goal determined in the protocol was lower than 85 Gy, there is room in improvement for local control. A higher dose might have been needed for tumors with poor responses.
