ABSTRACT

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 study focused on patients aged 70 years and above, evaluating various clinical and pathological variables. Univariate analysis was utilized to identify potential risk factors with to non-cancer-related mortality and to access prognostic outcomes. RESULTS: Out of the initial 684 patients, 244 elderly patients were included in the analysis, with 33 succumbing to non-cancer-related causes. Univariate analysis identified advanced age (≥ 80 years), low body mass index (BMI) (< 18.5), high Charlson Comorbidity Index (CCI), and the presence of overall surgical complications as significant potential risk factors for non-cancer related mortality. These factors also correlated with poorer overall survival and prognosis. The most common cause of non-cancer-related deaths were respiratory issues and heart failure. CONCLUSION: In elderly gastric cancer patients, managing advanced age, low BMI, high CCI, and minimizing postoperative complications are essential for reducing non-cancer-related mortality following curative surgery.

ABSTRACT

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. METHODS: We retrospectively investigated SSI surveillance data from July 2003 to December 2015. Two university hospitals and 25 university-affiliated hospitals participated in prospective SSI surveillance. Univariate and multivariate analyses were performed to detect significant associations. RESULTS: We investigated 9655 colon surgeries. The year in which surgery was performed was significantly associated with the SSI rate (p = 0.0381). The rate of laparoscopic surgery gradually increased during the study period, and by 2012 it was routinely used for > 50% of colon surgeries. Laparoscopic surgery became a significant factor associated with reduced SSI rates compared with conventional open surgery once the performance rate of laparoscopic surgery reached > 50%. CONCLUSIONS: Increasing rates of laparoscopic colon surgery tended to be associated with a reduction in the SSI risk after surgical treatment of colonic disease. The results of this study might encourage surgeons to view laparoscopic surgical techniques as an evidence-based approach for reducing the risk of SSI.

ABSTRACT

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. TTV was measured with 3D MRI. These and other clinicopathological parameters were statistically analyzed to determine the prognosis for the patients. Median follow-up time was 46 months (1-64 months). Of the 51 patients, 25 developed distant recurrences. Patients whose TTV decreased by 75% or more after PCT showed significantly better prognosis than others, while tumor size measured with calipers, US and 2D MRI showed no significant relationship with patient prognosis. Of the clinicopathological parameters, only reduction in TTV and histological grade showed a significant association with distant recurrence-free survival (p = 0.03 and 0.02, log-rank test), while stepwise multivariate Cox's proportional hazards analysis identified TTV as the strongest independent prognostic factor. Reduction in TTV measured with 3D MRI can be a useful prognostic factor for patients with locally advanced breast cancer treated with PCT.

ABSTRACT

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. In 20 patients, the catheter was easily and uneventfully removed after chemotherapy, which resulted in improved patients' quality of life. An electron microscope examination revealed that there was no fibrin network formation on the surface of the catheter. Stenosis of the hepatic artery was confirmed in 7 out of 12 patients with 5 Fr catheter by 3DCT angiography, whereas patency of the artery was well preserved in 7 of 8 cases with 3.3 Fr catheter. This catheter has a special shape-memory alloy in its tip, which allows a preferable fixation without coils and removal of the catheter if desired. HAI using this catheter and subsequent removal of it is a reasonable strategy especially for patients who need limited courses of chemotherapy.

ABSTRACT

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. A spiral zigzag stent of 8 cm in length was also inserted into the IVC through the femoral vein following balloon dilatation of the obstructed portion. Subsequently, jaundice and edema were dramatically improved in a short period of time, which resulted in patient discharge from the hospital. Although the patient died of the cancer in 2 months, the quality of life was well maintained until death.

ABSTRACT

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. Computed tomography showed chronic inflammatory change with bronchiectasis in the S6 segment of the right lung. The patient underwent video assisted thoracic surgery that identified two fistulae without missing a symptomatic one, and both were successfully resected. The fistulae were lined by squamous epithelium and smooth muscle without evidence of malignancy, infection or chronic inflammation that were histologically compatible with congenital fistulae.

ABSTRACT

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. There were no side effects except slight fever and general fatigue. We recognized a partial response, and the patient is still alive 14 months after hepatectomy. This case suggests that TAE with CDDP and DSM might be useful for prolonging the survival of advanced HCC patients.

ABSTRACT

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. In the remaining 3 cases in which the hepatic artery was smaller in diameter, a catheter was placed using the conventional GDA coiling method. Removal of the W-Spiral Catheter was attempted in 10 of the 13 patients with a Spiral Catheter after termination of HAI chemotherapy. In all cases, the catheters were easily and uneventfully removed, and 3D-CT angiography revealed that the hepatic artery was well preserved in most cases. These findings suggest that a new approach to prophylactic HAI chemotherapy with W-Spiral Catheters and subsequent removal of the catheters is reasonable and desirable.

ABSTRACT

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 11.8 months postoperatively, and only one patient received further regional chemotherapy for recurrent disease. These findings indicate that heparin administration to maintain the port brings little benefit. In the most recent 3 cases, we used a new Piolax W Spiral catheter and removed the catheter and port after cessation of adjuvant chemotherapy. No complication related to the procedure occurred, and patients' quality of life was well preserved, suggesting that this approach for HAI is reasonable and beneficial.
