A comprehensive study on non-cancer-related mortality risk factors in elderly gastric cancer patients post-curative surgery.

Background: The increasing incidence of gastric cancer in the elderly underscores the need for an in-depth understanding of the challenges and risks associated with surgical interventions in this demographic. This study aims to investigate the risk factors and prognostic indicators for non-cancer-related mortality following curative surgery in elderly gastric cancer patients.

Methods: This retrospective analysis examined 684 patients with pathological Stage I-III gastric cancer who underwent curative resection between January 2012 and December 2021.

The association between the increased performance of laparoscopic colon surgery and a reduced risk of surgical site infection.

Purpose: Surgical site infection (SSI) is the most frequently occurring nosocomial infection. Remarkable surgical progress has recently been made in laparoscopic surgery. Therefore, our objective was to investigate the association between increased rates of laparoscopic colon surgery and SSI.

Potential of reduction in total tumor volume measured with 3D-MRI as a prognostic factor for locally-advanced breast cancer patients treated with primary chemotherapy.

For accurate assessment of the response to primary chemotherapy (PCT) for locally advanced breast cancer, we measured reduction in total tumor volume (TTV) by using three-dimensional magnetic resonance imaging (3D MRI), and examined the relationship between this reduction and patient prognosis. Fifty-one patients with locally advanced breast cancer were treated with four cycles of docetaxel (60 mg/m(2)) before surgery. Tumor size was measured with calipers, ultrasonography (US) and conventional two-dimensional (2D) MRI before and after chemotherapy.

[Hepatic arterial infusion chemotherapy using W-spiral (WS) catheter].

The authors investigated the usefulness of W-Spiral (WS) catheters for hepatic arterial infusion (HAI) chemotherapy especially from the viewpoint of a removable catheter after cessation of chemotherapy. A WS catheter was successfully inserted into the hepatic artery without a coil fixation in 40 out of 47 patients with hepatic malignant disease. A stable position of the catheter tip was maintained throughout the period in all cases.

[Application of metallic stents for both inferior vena cava and biliary obstruction by lymph node involvement in a patient with recurrent hepatocellular carcinoma].

The authors experienced a case with obstruction of the inferior vena cava (IVC) and the common bile duct due to a recurrent hepatocellular carcinoma. In order to improve severe edema of the lower extremities and obstructive jaundice, IVC metallic stent as well as biliary stent were applied. A Luminexx stent of 8 cm in length was placed in the bile duct via subcutaneous route after biliary drainage.

Double congenital bronchoesophageal fistulae in an adult.

We report adult congenital bronchoesophageal fistula with both symptomatic fistula and asymptomatic one. A 56-year-old woman with a history of cough after drinking fluids was diagnosed as bronchoesophageal fistula by upper gastrointestinal series that showed a diverticulum in the middle portion of the esophagus with a fistula between the esophagus and right lower lung. Esophagoscopy revealed an orifice of the fistula located 27 cm from the incisors.

[Prophylactic hepatic arterial infusion chemotherapy after resection of colorectal liver metastases using removable W-spiral catheter].

The authors investigated the usefulness of W-Spiral Catheters for adjuvant hepatic arterial infusion (HAI) chemotherapy following curative resection of colorectal liver metastases. The catheter has a special shape-memory alloy in its tip, which allows preferable fixation without coils and removal of the catheter if desired. A W-spiral catheter was successfully placed in 13 out of 16 patients who had undergone curative hepatectomy.

[Successful treatment of postoperative multiple hepatic recurrence with hepatic arterial infusion of cisplatin and degrable starch microspheres].

A 38-year-old man had multiple recurrence of hepatocellular carcinoma (HCC) with portal vein thrombosis after hepatectomy and postoperative transcatheter arterial chemotherapy with 5-fluorouracil (5-FU). He was treated by trans hepatic arterial embolization (TAE) with 100 mg of cisplatin (CDDP) and degrable starch microspheres (DSM). After 3 courses were administered, the recurrent lesions almost disappeared on CT, and the postoperative rise in PIVKA-II level and AFP level normalized.

[Reasonable approach for prophylactic hepatic arterial infusion chemotherapy after potentially curative surgery for colorectal liver metastases].

The authors discuss the reasonable management of implantable ports and catheters after cessation of adjuvant hepatic arterial infusion (HAI) chemotherapy following curative resection of colorectal liver metastases. Local recurrence in the residual liver was observed in only 4 patients of thirty-two patients (13%). Although heparin administration into the port was regularly performed in 17 patients to prevent its occlusion, the ports were successfully maintained in only 9 patients at a median time of 11.
