Background: The purpose of this study was to investigate the early diagnosis and outcomes of surgical treatment of primary duodenal adenocarcinoma (PDAC) for curative purpose.
Method: Thirty-two PDAC patients treated surgically between February 1990 and September 2006 were analyzed retrospectively.
Results: All 32 patients underwent laparotomy, including 18 patients (56.3%) pancreaticoduodenectomy (PD), six patients (18.7%) segmental resection (SR), and eight patients bypass procedures. R0 resections were obtained in 22 patients; the other 10 procedures were palliative. The total 1-, 3-, and 5-year survival rates in this study were 86.2% (25/29), 48.3% (14/29), and 20.7% (6/29), respectively, moreover, the 1-, 3-, and 5-year survival rates in patients with R0 resection were 100.0% (19/19), 73.7% (14/19), and 31.6%(6/19), which were significantly higher than those (50.0% = 5/10, 0%, and 0%) in patients with palliative operation (P > 0.05), respectively. Furthermore, the 5-year survival rate was 27.8% (5/18) in pancreaticoduodenectomy patients and 16.7% (1/6) in segmental resection patients, and there was no significant difference between the above two procedures (P > 0.05).
Conclusion: PD is suggested for tumor located at the first and second portion of the duodenum, and SR may be appropriate for the selected patients, especially for tumors of the distal duodenum.

Overexpression of PLCG2 and TMEM38A inhibit tumor progression in clear cell renal cell carcinoma.
Sci Rep
January 2025
Department of Urology, Zhongnan Hospital of Wuhan University, Wuhan, China.
Clear cell renal cell carcinoma is a prevalent urological malignancy, imposing substantial burdens on both patients and society. In our study, we used bioinformatics methods to select four putative target genes associated with EMT and prognosis and developed a nomogram model which could accurately predicting 5-year patient survival rates. We further analyzed proteome and single-cell data and selected PLCG2 and TMEM38A for the following experiments.

Department of Orthopaedic Surgery and Traumatology, Odense University Hospital, Denmark; Department of Orthopaedic Surgery and Traumatology, Lillebaelt Hospital - University Hospital of Southern Denmark, Denmark; Department of Clinical Research, University of Southern Denmark, Denmark.
Background: Proximal femoral fractures has been associated with high mortality risk, while little is known about more distal lower extremity fractures. The aim was to report 30- and 365-days mortality in surgically treated lower extremity fractures in individuals above 65 years.
Materials And Methods: We extracted data from the Danish National Patient Register on all surgically treated lower extremity fracture in the period 1998-2017.

Purpose: Adrenocortical carcinoma (ACC) is a rare malignancy known for high rates of recurrence and poor prognosis. Previous studies revealed controversial roles of adjuvant radiation therapy (RT) in patient management. This study aimed to investigate the role of adjuvant RT in postoperative ACC patients.

Background: Non-Hodgkin lymphoma (NHL) is the seventh most common cancer among Asian, Native Hawaiian and Pacific Islanders (ANHPIs), yet the risk of death in specific ANHPI subgroups in the US is unknown.
Methods: We used Surveillance, Epidemiology, and End Results data to investigate relative survival and the risk of death among NHL patients in ANHPI subgroups. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals (CI), comparing ANHPI subgroups to non-Hispanic White (NHW) NHL patients for all-cause death and NHL-specific death.
