The cachexia index is a prognostic factor for patients with recurrent pancreatic cancer.

PURPOSE: Cancer cachexia leads to poor outcomes, especially for patients with advanced stage disease. The cachexia index (CXI), a novel biomarker for cancer cachexia, has been identified as a prognostic indicator for several malignancies. The present study aimed to clarify the prognostic significance of the CXI for patients with recurrent pancreatic cancer. METHODS: This retrospective study enrolled 113 patients diagnosed with recurrence following pancreatectomy for pancreatic cancer, to analyze the association between the CXI and prognostic survival. RESULTS: The 2-year overall survival rate and median survival of all patients were 28.5% and 12.6 months, respectively. The 2-year overall survival curve in the high CXI group was significantly better than that in the low CXI group (p < 0.001). The rate of chemotherapy after recurrence was significantly lower in the low CXI group than in the high CXI group (p = 0.002). Multivariate analysis identified the CXI as an independent prognostic factor for patients with recurrent pancreatic cancer (p = 0.011). CONCLUSIONS: The CXI proved useful for predicting the post-recurrence prognosis of patients with recurrent pancreatic cancer. Patients with a low CXI at the time of recurrence have poorer prognostic outcomes than those with a high CXI.

Correlation between relative dose intensity of adjuvant S-1 chemotherapy and psoas muscle mass volume and survival after resection of pancreatic ductal adenocarcinoma: A retrospective study.

This study aimed to investigate the prognostic relationship between relative dose intensity (RDI) of adjuvant S-1 chemotherapy and psoas muscle mass volume (PMV) in patients with resected pancreatic ductal adenocarcinoma. We enrolled 105 patients with histologically confirmed pancreatic ductal adenocarcinoma who had undergone pancreatectomy. Adjuvant S-1 chemotherapy was administered to 72 (68.6%) of the 105 patients and not to the remaining 33 patients. Patients who received adjuvant S-1 chemotherapy were stratified into high- and low-RDI groups by the cutoff value for RDI. Five-year overall survival (OS) and relapse-free survival (RFS) rates were significantly higher in the high- than in the low-RDI group. Similarly, both the 5-year OS and RFS rates were significantly greater among patients in the high-PMV group than among patients in the low-PMV group. The RDI was an independent prognostic factor in our study patients. Furthermore, patients who received adjuvant S-1 chemotherapy were stratified into 3 groups: those with both high RDI and high-PMV, Group A; those with either high RDI or high PMV (but not both), Group B; and those with both low RDI and low-PMV, group C. There were statistically significant differences in 5-year OS and RFS between 3 patient groups (5-year overall survival: P = .023, 5-year relapse-free survival: P = .001). The area under the curve for the combination of RDI and PMV (0.674) was greater than that for RDI alone (0.645). A sufficient dosage of adjuvant S-1 chemotherapy is important in improving survival of patients with resected pancreatic ductal adenocarcinoma. A combination of RDI and PMV may predict the prognosis of patients with resected pancreatic ductal adenocarcinoma more effective than RDI alone.

An Intrahepatic Fluorodeoxyglucose (FDG)-PET/CT False-Positive Tumor Secondary to Foreign Body Granuloma Masquerading as Colon Cancer Liver Metastasis: A Case Report.

A suture placed next to a dissected liver section during the initial hepatectomy may become an unlikely intrahepatic foreign body granuloma. In this report, we describe a case where a silk suture in the liver section plane placed during initial hepatectomy for synchronous colon cancer metastasis became an intrahepatic foreign body granuloma that exhibited fluorodeoxyglucose (FDG) accumulation on positron emission tomography/computed tomography (PET/CT). The granuloma was resected as the second metachronous liver metastatic lesion. A 73-year-old female was referred for a planned second hepatectomy. She had undergone colectomy and hepatectomy for advanced cancer of the ascending colon and synchronous liver metastasis approximately two years ago. However, two possible liver metastases with FDG accumulation were identified in hepatic segments IV and V after one year and nine months after the initial resection. A second hepatectomy was planned after administering systemic chemotherapy. She underwent a left lobectomy with a middle hepatic vein and partial segment V hepatectomy six months after liver lesion identification. The segment IV lesion was histologically proven to be a liver metastasis adenocarcinoma. The segment V lesion revealed a silk thread on the residual liver side at the initial hepatectomy, which was histologically diagnosed as a foreign body granuloma. The possibility of intrahepatic foreign body granuloma development should be considered in subsequent follow-ups in cases where sutures were applied to the dissected residual liver plane during the initial hepatectomy. Additionally, a thorough second hepatectomy should be considered if recurrence is suspected.

Hepatectomy for massive hepatic necrosis after transcatheter arterial embolization hemostasis for hepatic hemorrhage following hepatic trauma: A case report.

Key Clinical Message: Although partial hepatic necrosis often occurs following endovascular treatment for bleeding associated with hepatic trauma, it is relatively rare that additional treatment is required. However, invasive procedures such as hepatic resection should sometimes be considered when infection occurs over massive hepatic necrosis. Abstract: Although partial hepatic necrosis following endovascular treatment for bleeding associated with hepatic trauma is occasionally experienced, it is relatively rare for the necrotic area of the liver to require additional treatment. However, invasive procedures such as hepatic resection should sometimes be considered when infection occurs over massive hepatic necrosis.

Surgical Outcomes of Robotic Distal Pancreatectomy Versus Laparoscopic Distal Pancreatectomy at a Hospital in a Sparsely Populated Area.

Background: Robotic distal pancreatectomy (RDP) has a better or comparable surgical outcome when compared with laparoscopic distal pancreatectomy (LDP). However, whether the surgical outcome for these procedures in local, low-volume hospitals are comparable with those of the typically larger centers described in published reports remains unclear. Methods: This study enrolled 48 patients who underwent either RDP or LDP between August 2012 and April 2023. Data were retrospectively analyzed to evaluate the short-term surgical outcomes of RDP versus LDP in our hospital, which is a low-volume center. Results: The use of stapling with reinforcement in RDP was significantly higher than in LDP, and the postoperative hospital stay for RDP was significantly shorter than for LDP. Except for these two variables, there were no statistically significant differences between RDP and LDP in preoperative, intraoperative, or postoperative patient characteristics. Conclusion: RDP can be performed as safely and effectively as LDP in a low-volume hospital located in a sparsely populated area.
