Background This study aimed to investigate the changes in the histological types and causes of death associated with thyroid carcinoma (TC) before and after the introduction of systemic drug therapy. Methods The records of 503 deceased patients treated for TC and with death from TC between January 2005 and June 2024 were reviewed in this retrospective cohort study. Multivariate logistic regression was applied to assess whether the number of patients with anaplastic TC (ATC) at the diagnosis and the number of local-related deaths changed before and after the introduction of Lenvatinib (i.

Background/aim: Malnutrition is a reported prognostic factor in patients with cancer. The controlling nutritional status (CONUT) score, an index calculated from routine laboratory tests, is correlated with the prognosis of various cancers. This study examined the relationship between the CONUT score and prognosis of patients with gastric cancer (GC) after radical gastrectomy.

Background/aim: Neoadjuvant chemotherapy is gaining recognition for its potential to improve survival outcomes, with combined neoadjuvant and adjuvant therapies under investigation. However, the prognostic significance of post-chemotherapy pathological staging (ypStage) on recurrence-free survival (RFS) remains unclear. This study aimed to evaluate the utility of ypStage, ypT, ypN classification, and histological response rate in predicting recurrence after gastrectomy.

Background/aim: Patients with unresectable advanced and recurrent colorectal cancer (CRC) and the mutation have poor prognosis, and conventional chemotherapy is often ineffective. This study aimed to retrospectively evaluate the clinicopathological features and prognosis of this patient population.

Patients And Methods: We examined clinicopathological characteristics and treatment outcomes of 26 patients with -mutated unresectable advanced and recurrent CRC treated between June 2015 and October 2022.

Background/aim: Esophageal cancer (EC) is a malignant tumor with poor prognosis. Prognostic factors that may be used in the treatment and management of EC are important. The purpose of this study was to evaluate the impact of the hemoglobin, albumin, lymphocyte, and platelet (HALP) score on the long-term oncological prognosis of patients with EC who have undergone curative treatment.

Introduction: An ilio-iliac arteriovenous fistula (IIAVF) secondary to the rupture of a common iliac artery aneurysm (CIAA) is rare. Sudden arteriovenous shunting and subsequent fistula enlargement can result in acute cardiac failure. Immediate diagnosis and treatment are required; however, the clinical symptoms differ from those of a free wall rupture of an aortic aneurysm, making a quick diagnosis difficult.

We investigated the clinical outcomes of gastrectomy in 7 patients over 90 years of age. Four patients were male and 3 were female. The tumor was located in the U region in 1 patient, M region in 2, and L region in 4.

A 77-year-old man presented to our hospital with anemia and was diagnosed with a high-risk gastrointestinal stromal tumor (GIST)of the stomach on abdominal CT scan and endoscopic ultrasound-guided fine-needle biopsy. One month after initiating the neoadjuvant imatinib therapy, the patient was admitted to our hospital for fever and was diagnosed with an intratumoral infection. Antibiotic therapy was immediately initiated, and upper gastrointestinal endoscopy revealed a fistula between the stomach and tumor; therefore, endoscopic drainage was performed through the fistula.

Background/aim: Perioperative rehabilitation is effective in preventing postoperative complications and is associated with a shorter length of hospital stay after gastrectomy. However, its impact on short-term outcomes in patients without post-gastrectomy complications has not yet been clarified. This study aimed to evaluate the usefulness of perioperative rehabilitation beyond preventing postoperative complications.

Purpose: To investigate changes in eye alignment before and after ICL implantation in patients with myopia having corrected distance visual acuity (CDVA) of ≥0.0 logMAR.

Subjects And Methods: The medical records of 1012 patients without eye movement limitation who underwent bilateral ICL implantation were retrospectively reviewed a at the Eye Center of Sanno Hospital in Japan.

Purpose: In recent years, major advancements have been made in rectal cancer surgery with the introduction of new techniques such as robotic surgery and indocyanine green fluorescence imaging (ICG-FI). This study aimed to evaluate the comprehensive risk factors for anastomotic leakage (AL) following rectal cancer surgery, incorporating recently introduced techniques and other existing factors, to reflect current practices.

Methods: A retrospective analysis was conducted of 304 patients who underwent either robotic or laparoscopic anterior resection between January 2019 and December 2023.

Aim: The risk of lymph node metastasis after endoscopic resection of high-risk T1 colorectal cancer prompts additional resection. However, age and comorbidities are considered in decision-making and some surgeons opt for observation. We compared the long-term outcomes of these approaches with the aim of clarifying the need for additional resection.

Background/aim: The aim of the present study was to evaluate the clinical impact of the Global Immune-Nutrition-Information Index (GINI) in patients with esophageal cancer (EC) who received curative treatment and to clarify the potential of the GINI as a prognostic factor.

Patients And Methods: Patients who underwent curative resection for EC at Yokohama City University between 2000 and 2020 were consecutively chosen based on their medical records. The GINI was defined as follows: GINI=[C-reactive protein×platelet×monocyte×neutrophil]/[albumin×lymphocyte].

Summary: A 56-year-old woman with cervical pain with a history of ovarian clear cell carcinoma stage IIIC was admitted to a primary care doctor. Ultrasonography revealed a microhyperechoic nodule in the thyroid gland and cervical lymph node enlargement, and fine-needle aspiration was performed. The results showed malignancy, and she was admitted to our hospital.

A 73-year-old male was admitted to our hospital due to fever and right lower limb pain. Contrast-enhanced computed tomography (CT) revealed occlusion from the right common femoral artery to the right superficial femoral artery and from the left common iliac artery to the left internal and external iliac arteries, leading to a diagnosis of bilateral acute arterial occlusion of the lower extremity. Emergency thrombectomy was performed to improve arterial blood flow.

Article Synopsis
  • This study examined how anemia affects short- and long-term outcomes in patients with resectable gastric cancer undergoing curative treatment.
  • A total of 330 patients were reviewed, revealing that those with preoperative hemoglobin levels below 11 g/dl had significantly lower survival rates compared to those with higher levels.
  • The findings suggest that addressing perioperative anemia could improve the overall survival and reduce complications for gastric cancer patients receiving treatment.

Article Synopsis
  • The study investigates the impact of warm ischemia time (WIT) on the expression of HER2, a protein important in breast cancer diagnostics, hypothesizing that hypoxia during WIT may increase HER2 IHC scores.
  • Researchers measured HER2 mRNA levels in breast cancer cell lines and found that hypoxia increased the presence of HER2 on the cell membrane but did not affect its mRNA levels.
  • The conclusion emphasizes that while HER2 mRNA isn’t upregulated by hypoxia, the amount of HER2 protein on the membrane surfaces does increase, suggesting an important distinction in how HER2 is expressed in hypoxic conditions.

Article Synopsis
  • * A study involving 277 breast cancer patients examined the effects of WIT, CIT, and FT on the expression of estrogen receptors (ER), progesterone receptors (PgR), and HER2 in surgical specimens compared to preoperative biopsies.
  • * Findings showed that while ER and PgR expressions tended to decrease with longer CIT and FT, only HER2 expression was significantly affected by WIT exceeding 30 minutes, indicating the importance of

Purpose: Reports on the association of perioperative nutritional and inflammatory status with the clinical course of adjuvant chemotherapy did not include neoadjuvant chemotherapy. We aimed to clarify the mechanism by which perioperative nutritional and inflammatory status affect the clinical course of postoperative adjuvant chemotherapy in patients with pancreatic cancer.

Methods: We enrolled 123 patients with pancreatic cancer retrospectively who underwent surgical resection with neoadjuvant and S-1 adjuvant chemotherapy between January 2013 and December 2022.
