Bladder preservation with concurrent chemoradiotherapy for muscle-invasive bladder cancer: Retrospective comparison of three regimens.

Objectives: The objectives of the study are to evaluate the oncological and functional outcomes of three bladder preservation regimens: radiotherapy alone (RT-alone group), concurrent chemoradiotherapy (CRT) using gemcitabine plus platinum (GP-RT group), and low-dose gemcitabine (LD-Gem-RT group) for muscle-invasive bladder cancer.

Methods: The three oncological outcomes, bladder-intact distant metastasis-free survival (BI-DMFS), cancer-specific survival, and overall survival (OS), were compared among RT alone ( = 10), GP-RT ( = 16), and LD-Gem-RT ( = 11) groups. Treatment-related adverse events were evaluated against the Common Terminology Criteria for Adverse Events (version 5.

A Multicenter, Single-Arm, Prospective Trial to Evaluate Efficacy and Safety of Dose-Dense Methotrexate, Vinblastine, Doxorubicin, and Carboplatin (DD-MVACarbo) Chemotherapy for Cisplatin-Ineligible Patients with Advanced Urothelial Cancer: Study Protocol of the CARBUNCLE Trial.

Unresectable, metastatic, advanced urothelial carcinoma (aUC) is an aggressive disease and is treated with platinum-containing first-line chemotherapy, followed by immune checkpoint inhibitors and antibody-drug conjugates. Response to first-line chemotherapy is a vital priority in sequential treatment strategies because a better response to first-line chemotherapy is associated with a better response to subsequent therapies. Gemcitabine plus carboplatin chemotherapy is conventionally recommended for cisplatin-ineligible patients.

Comparison of Quality of Recovery between Modified Thoracoabdominal Nerves Block through Perichondrial Approach versus Oblique Subcostal Transversus Abdominis Plane Block in Patients Undergoing Total Laparoscopic Hysterectomy: A Pilot Randomized Controlled Trial.

Modified thoracoabdominal nerves block through a perichondrial approach (M-TAPA) provides a wide analgesic range. Herein, we examined the quality of recovery (QoR) of M-TAPA for total laparoscopic hysterectomy (TLH) compared with oblique subcostal transversus abdominis plane block (OSTAPB) and measured plasma levobupivacaine concentrations (PC). Forty female patients undergoing TLH were randomized to each group.
