To investigate whether lymphatic fluid stagnation at the pelvis causes NB, we investigated the effectiveness of lymphaticovenular anastomosis (LVA) for NB.

Methods: In this retrospective study between 2014 and April 2024, LVA was performed on 52 patients complaining of preoperative urinary dysfunction with lower extremity lymphedema following pelvic lymphadenectomy in gynecologic cancer treatment.

L-Shaped Scapular and Parascapular Combined Flap for Reconstruction of a Large Surface Defect After Sarcoma Resection Using ICG Angiography: A Case Series of 6 Patients.

Background: Soft tissue sarcomas (STS) pose challenges in management due to large defects following wide resection. Reconstructive options are often limited, especially in patients with large circular defects below the gluteal region. This article addresses the question of how to effectively reconstruct such defects while minimizing donor-site morbidity.

Posthepatectomy Liver Failure in Patients with Splenomegaly Induced by Induction Chemotherapy for Colorectal Liver Metastases.

Purpose: With advances in chemotherapy, conversion surgery is often performed for initially unresectable colorectal cancer liver metastasis (CLM). However, unexpected posthepatectomy liver failure (PHLF) is sometimes associated with chemotherapy-associated liver injuries following long-term chemotherapy. We aimed to identify predictive factors for PHLF after conversion surgery for initially unresectable CLM.

Clinical Outcomes and Prognostic Factors for R0 Resected Colorectal Cancer with Synchronous Peritoneal Metastasis: A Retrospective Study.

Objectives: Peritoneal metastasis indicates a poor prognosis in patients with colorectal cancer (CRC). Studies have shown improved prognosis in patients after removal of peritoneal dissemination, and this surgery is recommended if not excessively invasive. The aim of this study was to examine clinical outcomes and prognostic factors for R0 resected CRC with synchronous peritoneal metastasis.

Neoadjuvant chemoradiotherapy is associated with prolonged relapse free survival in patient with MRI-detected extramural vascular invasion (mrEMVI) positive rectal cancer: A multicenter retrospective cohort study in Japan.

Purpose: Neoadjuvant chemoradiotherapy (nCRT) is employed for the local control of locally advanced rectal cancer; however, its prognostic impact is limited and often impairs pelvic organ function. Therefore, careful patient selection is essential. This study aimed to investigate the impact of nCRT on relapse-free survival (RFS) by stratifying patients according to MRI detected circumferential resection margin (mrCRM) or extramural vascular invasion (mrEMVI), as the ability of MRI findings to identify patients who will have beneficial outcomes from nCRT is uncertain.

Phase I/II study of nivolumab plus lenvatinib for advanced biliary tract cancer (JCOG1808/NCCH1817, SNIPE).

Background: Although cisplatin plus gemcitabine and other combinations have improved the survival of advanced biliary tract cancer (BTC), high unmet medical needs remain. This study aimed to assess the efficacy and safety of nivolumab plus lenvatinib in the second-line treatment for advanced BTC.

Patients And Methods: Nivolumab (240 mg) was administered biweekly.

Potential of the Thoracoepigastric Vein as a Drainage Vein in Breast Reconstruction With a Free Flap: An Anatomical Study Using Computed Tomography.

Background: The recipient vessel choice is very important when performing free-flap breast reconstructions. Usually, the concomitant vein of the recipient artery is anastomosed, and mismatches in the diameter are occasionally observed. We consider the thoracoepigastric vein (TEV) as a potential useful recipient vein.

Integrating surgical intervention and watch-and-wait approach in dMMR metastatic rectal cancer with pembrolizumab: a case report.

Background: Treating rectal cancer presents challenges due to postoperative complications and reduced quality of life (QOL). Recent evidence supports the watch-and-wait (WW) approach for patients with a clinical complete response (cCR) following preoperative treatment. In this report, we discuss a case of metastatic rectal cancer with deficient mismatch repair (dMMR) treated successfully with pembrolizumab.

Esophagectomy for esophageal cancer in patients with a history of total pharyngolaryngectomy: a Japanese nationwide retrospective cohort study.

Background: Second primary esophageal cancer often develops in patients with head and neck cancer, and esophagectomy in patients with a history of total pharyngolaryngectomy (TPL) is challenging. However, the clinical outcomes of these patients have yet to be examined in a multicenter setting.

Methods: We evaluated the surgical outcomes of a nationwide cohort of 62 patients who underwent esophagectomy for esophageal cancer with a history of TPL.

Indocyanine Green Lymphography-guided Lymphatic Vessel Suture Ligation for Superficial Abdominal Flap Donor Site for Breast Reconstruction.

Autologous breast reconstruction using the abdominal flap based on the superficial system has the potential to minimize donor-site morbidity. Although efforts to improve its transfer have been focused, there have been scarce attempts to further reduce donor-site complications in the abdomen. Seroma formation is a significant complication after the superficial based abdominal flap harvest.

Cytoreductive surgery without intra-peritoneal chemotherapy for metachronous colorectal peritoneal metastases.

Background: Cytoreductive surgery and chemotherapy reportedly improve the prognosis of patients with metachronous peritoneal metastases. However, the types of peritoneal metastases indicated for cytoreductive surgery remains unclear. Therefore, we aimed to clarify the category of cases for which cytoreductive surgery would be effective and report the prognosis associated with cytoreductive surgery for metachronous peritoneal metastases.

Phase I study of the safety and clinical activity of the interleukin-8 inhibitor AMY109 combined with atezolizumab in patients with advanced solid cancers.

Background: Immunosuppressive conditions within the tumor microenvironment (TME) can allow tumors to evade the immune system, including by hampering programmed death ligand 1 (PD-L1) inhibitor activity. Interleukin (IL)-8 contributes to immunosuppression and fibrosis in the TME. AMY109, a humanized anti-IL-8 monoclonal antibody, reduced fibrosis and decreased immunosuppressive cells in tumor tissue in animals.

Potent therapeutic strategy in gastric cancer with microsatellite instability-high and/or deficient mismatch repair.

Gastric cancer (GC) is a common malignancy that presents challenges in patient care worldwide. The mismatch repair (MMR) system is a highly conserved DNA repair mechanism that protects genome integrity during replication. Deficient MMR (dMMR) results in an increased accumulation of genetic errors in microsatellite sequences, leading to the development of a microsatellite instability-high (MSI-H) phenotype.
