Lymphaticovenular anastomosis (LVA) is the first-line surgical treatment for lymphedema. The therapeutic effects of LVA, including edema reduction and cellulitis prevention, vary among patients. We examined cases of palliative LVA in patients with lymphedema who were in the terminal stage due to recurrence or distant metastasis of the primary disease, with a focus on the course and usefulness of palliative LVA.

We introduce here a novel, noninvasive urinary extracellular vesicle miRNA-based assay for the detection of pancreatic cancer from early to late stages.
Methods: From September 2019 to July 2023, Urine samples were collected from patients with pancreatic cancer (n = 153) from five distinct sites (Hokuto Hospital, Kawasaki Medical School Hospital, National Cancer Center Hospital, Kagoshima University Hospital, and Kumagaya General Hospital) and non-cancer participants (n = 309) from two separate sites (Hokuto Hospital and Omiya City Clinic).
Background: Melanoma is a highly malignant cancer responsible for 55 000 deaths worldwide annually. Despite its severity, its epidemiology in Japan remains understudied owing to its rarity among Asians. This study aimed to determine the incidence of melanoma in Japan using data from the National Cancer Registry.

Breast reconstruction primarily falls into two categories: implant-based techniques and autologous tissue transfers. In this study, we present a comprehensive review of various aspects of implant-based reconstruction, including different types of implants, surgical techniques, and their respective advantages and disadvantages.

Aims: We evaluated the HER3 expression status after chemotherapy for pancreatic cancer and its association with clinicopathological features and clinical outcomes.
Materials & Methods: We included patients with pancreatic cancer who underwent chemotherapy and whose post-treatment archival tissue specimens were collected.
Background: The combination of immune checkpoint inhibitors and chemotherapy has shown promising results for the treatment of advanced biliary tract cancer (BTC). Based on the results of the TOPAZ-1 trial, a gemcitabine and cisplatin plus durvalumab (GCD) regimen was recently approved as first-line therapy for patients with advanced BTC. However, post-GCD conversion surgery has not been previously studied.

The patient was a 71-year-old male with hypopharyngeal carcinoma who underwent right-sided neck dissection for lymph node metastasis, adjuvant radiotherapy (70 Gy), and cisplatin chemotherapy, he developed neck inflammation with evidence of free air on computed tomography and subcutaneous fistula formation on laryngoscopy. After total laryngectomy, bilateral neck vessels were obscured by scar tissue secondary to radiotherapy and chronic inflammation. Pedicled pectoralis major (PM) flap was favored for reconstruction.

In this article, we report on the main points of super microsurgery, particularly on the anastomosis of veins and lymphatic vessels with diameters smaller than 0.

We analyzed Japanese domestic statistics for visceral sarcoma, using the National Cancer Registry (NCR) in Japan, a population-based database launched in 2016.
Methods: We identified 3245 cases of visceral sarcomas in the NCR dated 2016-2019 to analyze demographic and disease information, initial diagnostic process, volume and type of the hospitals, treatment, and prognosis.
Background: Clear cell sarcoma is rare, so no reports have previously characterized its national profiles. We examined the nationwide epidemiology and clinical outcomes of patients with clear cell sarcoma based on the National Cancer Registry in Japan.
Methods: Overall, 23 522 patients with soft tissue sarcoma-entered in the National Cancer Registry in 2016-2019 using the International Classification of Diseases for Oncology, Third Edition cancer topography and morphology codes-were enrolled in either the clear cell or the non-clear cell sarcoma group.
Background: The TOPAZ-1 phase III trial showed a survival benefit with durvalumab plus gemcitabine and cisplatin in patients with advanced biliary tract cancer (BTC). To understand this combination's real-world efficacy and tolerability, we conducted a global multicenter retrospective analysis of its first-line treatment outcomes.
Methods: We included patients with unresectable, locally advanced, or metastatic BTC treated with durvalumab, gemcitabine, and cisplatin at 39 sites in 11 countries (Europe, the United States, and Asia).
Background: No previous reports have characterized national profiles of soft-tissue sarcoma overall. We examined the nationwide statistics for soft-tissue sarcoma in Japan using data from the population-based National Cancer Registry.
Methods: We identified 23 522 soft-tissue-sarcoma patients who were entered in the National Cancer Registry during 2016-19 using International Classification of Diseases-Oncology, Third Edition codes for cancer topography and morphology.
Background: The safety and outcome of breast reconstruction after radiotherapy are controversial, and the aesthetic aspects have not been studied extensively. We compared the results of vascular anastomosis, the incidence of postoperative complications, and aesthetic appearance between patients who had and had not received radiotherapy who then had undergone delayed breast reconstruction with autologous free flaps from the abdomen, thighs, and buttocks.
Methods: In total, 257 flaps in 241 patients were investigated; 194 and 63 flaps implanted in patients who did not receive radiotherapy and who received radiotherapy before breast reconstruction, respectively.
Background: No previous reports have characterized national bone sarcoma profiles overall. We examined the nationwide statistics for bone sarcoma in Japan using data from the National Cancer Registry (NCR), a population-based cancer registry.
Methods: We identified 3,755 patients with bone sarcomas entered in the NCR during 2016-2019 using International Classification of Diseases-Oncology, Third Edition codes for cancer topography and morphology.
Various cytochrome P450 enzymes (CYPs) that contribute to drug metabolism are expressed in the skin. However, variation among individuals in CYP expression profiles is not well-understood.To investigate CYPs related to the metabolism of transdermal preparations in Japan, multiple skin tissue specimens of individuals of Japanese descent were prepared, and the mRNA expression levels of , , and were measured.

In our case series of six unresectable pancreatic cancer patients with tumor bleeding, we explored the efficacy and safety of placement of a covered self-expandable metallic stent in the duodenum as a treatment option; we achieved a hemostasis rate of 67% (4/6), with a rebleeding rate of 50% (2/4). No complications occurred with stent placement, except for food impaction in one patient.

Methods: We retrospectively investigated PC patients with peritoneal dissemination who had received GnP as first-line chemotherapy at our institution between March 2015 and August 2021. The following patient data were reviewed: patient characteristics, overall survival (OS), progression-free survival (PFS), objective response rate (ORR), adverse events (AEs), and relative dose intensity (RDI).
Associations of exertional heat exhaustion (EHE)-related symptoms with lifestyle habits and health factors specific to female athletes, ranked by relative risks from high to low, remain elusive. Addressing this issue would benefit athletes and coaches, ensuring safer practices during summer sports activities. To address this issue, we distributed paper-based questionnaires to seven universities in Japan, and 983 respondents completed our survey.
