Left-sided appendicitis due to situs inversus totalis.

Situs inversus may mimic the pain localization of acute abdomen. In patients with acute abdomen, especially elderly patients who are medically healthy, physicians should cautiously diagnose the etiology of acute abdomen in combination with imaging studies.

Photoimmunotherapy for cancer-associated fibroblasts targeting fibroblast activation protein in human esophageal squamous cell carcinoma.

Cancer-associated fibroblasts (CAFs) are strongly implicated in tumor progression, including in the processes of tumorigenesis, invasion, and metastasis. The targeting of CAFs using various therapeutic approaches is a novel treatment strategy; however, the efficacy of such therapies remains limited. Recently, near-infrared photoimmunotherapy (NIR-PIT), which is a novel targeted therapy employing a cell-specific mAb conjugated to a photosensitizer, has been introduced as a new type of phototherapy.

Iron depletion enhances the effect of sorafenib in hepatocarcinoma.

ABSTACT Human hepatocellular carcinoma (HCC) is known to have a poor prognosis. Sorafenib, a molecular targeted drug, is most commonly used for HCC treatment. However, its effect on HCC is limited in clinical use and therefore new strategies regarding sorafenib treatment are required.

[A Patient with Gastric Cancer with Peritoneal Dissemination Who Survived for Five Years after Sequential Chemotherapy with S-1 Followed by Paclitaxel].

A 76-year-old man complained of hematemesis and melena, and consulted the doctor. An endoscopic examination revealed type 3 advanced gastric cancer and a gastric ulcer with a visible vessel. We performed total gastrectomy with peritoneal metastasis dissection.

Storage of washed platelets in BRS-A platelet additive solutions based on two types of clinically available bicarbonated Ringer's solutions with different electrolyte concentrations.

Background: In Japan, no platelet (PLT) additive solutions (PASs) are officially approved for clinical use although blood centers often receive requests for washed PLTs to reduce adverse reactions. Recently, we developed a novel PAS called BRS-A based on clinically available bicarbonated Ringer's solution (BRS), Bicanate and acid-citrate-dextrose formula A (ACD-A), which has been shown to maintain the in vitro properties of PLTs in the condition of <5% residual plasma during 7-day storage. The aim of this study was to evaluate whether another clinically available BRS, Bicarbon with different electrolyte concentrations can be used as a PAS.

[A case of long-term survival in P1CY1 gastric cancer responding to combined chemotherapy with low-dose CDDP intraperitoneal administration].

We reported a case of P1CY1 gastric cancer with intraperitoneal chemotherapy after surgery for more than four years. The patient was a 69-year-old male who had suffered from Type I+Type 0 IIc, T3 gastric cancer. He underwent total gastrectomy with D2 dissection.
