Surgery, radiotherapy (RT), and brachytherapy are crucial treatments for localized deep tumors. However, imprecise tumor location often leads to issues such as positive surgical margins, extended target volumes, radiation damage healthy tissues. Reducing side effects in tissue enhancing RT efficacy critical challenges. To address these issues, we developed a multifunctional theranostic platform using Au/Ag nanodots (Au/AgNDs) that act "pilot light" real-time guided surgery, high-efficiency...

Abstract Human leukocyte antigen (HLA) class I allelic genotypes were determined in 105 unrelated Han ethnic individuals inhabiting the northern China area. A total of 19 HLA‐A alleles, 49 HLA‐B alleles and 24 HLA‐Cw detected. Through analyses two three loci haplotypes HLA‐A, HLA‐B, HLA‐C loci, 11 HLA‐A‐B‐Cw haplotypes, HLA‐A‐B 18 HLA‐A‐Cw HLA‐B‐Cw with frequencies higher than 0.01 revealed. The Nei's genetic distance (GD) was estimated, NJ dendrogram showed that Northern had a GD to...

Locally recurring cervical cancer after surgery and adjuvant radiotherapy remains a major therapeutic challenge. This paper presents new technique for such patients: interstitial brachytherapy (BT) guided by real-time three-dimensional (3D) computed tomography (CT).Sixteen patients with recurrent radical external-beam (EBRT) were included in this study. These underwent high-dose-rate (HDR) BT free-hand placement of metal needles 3D-CT. Six Gy 6 fractions prescribed the high-risk clinical...

The Radiation Therapy Oncology Group reported a maximum tolerated dose of 74 Gy for patients with non-small cell lung cancer (NSCLC); however, it was unclear whether this could be safely administered to Asian due differences in their physique compared Western patients. We therefore conducted modified Phase I trial determine 70 delivered Chinese NSCLC undergoing 3D-conformal radiation therapy (3D-CRT) concurrent chemotherapy. Previously untreated received 3D-CRT (2 Gy/day, 5 fractions per...
