Article Abstract
Background And Objectives: To identify clinicopathologic variables that could predict pathologic tumor response to neoadjuvant chemotherapy for patients with locally advanced gastric cancer.
Methods: The study enrolled 108 patients who underwent neoadjuvant chemotherapy followed by surgery between July 2004 and December 2010. Tumor responses to neoadjuvant chemotherapy were assessed in terms of tumor regression. Statistical analyses were performed to identify factors associated with pathologic tumor response.
Results: Tumor regression was found in 22.2% (24/108) patients, patients with tumor regression observed better overall survival as compared to that of patients without tumor regression. Univariate and multivariate analyses observed that both tumor differentiation and tumor size were independent predictors of tumor regression.
Conclusions: This study suggests that both tumor differentiation and tumor size is the most important clinical predicator of pathologic tumor response, it may be of benefit in the selection of treatment options in locally advanced gastric cancer.

Aim: Breast cancer is the most common cancer in women and is a leading cause of cancer-related mortality. The role of neoadjuvant therapy (NAT) in conjunction with surgical intervention is becoming increasingly prominent in the field of oncology. NAT enhance the probability of breast-conserving surgery in cases of locally advanced breast cancer and in patients with metastatic or inoperable disease.

The incidence of lung cancer is the highest among all tumors, and treatment has become an urgent problem to be solved. The Drug-eluting bead-based bronchial arterial chemoembolization (DEB-BACE) combination immunotherapy is a rare neoadjuvant therapy for lung cancer surgery, which can significantly reduce the time it takes for lung cancer patients to undergo surgery.We report a male patient, aged 59-year-old, with Stage-III b squamous cell lung cancer accompanied by hemoptysis underwent surgical resection after DEB-BACE combination immunotherapy treatment 21 days later without obvious adverse events.

Anal Melanoma (AM) is a rare and aggressive disease lacking standardized treatment protocols. Despite advancements in medical oncology, the 5-year overall survival (OS) remains at 20%. Local surgery (LS) has gained popularity over radical surgery (RS) due to its comparable OS when negative margins are achieved.

Background: Laparoscopic radical antegrade modular pancreatosplenectomy combined with celiac axis resection and portal vein reconstruction is a new procedure for the treatment of pancreatic cancer. This surgical technique may offer patients with pancreatic cancer involving the portal vein and celiac axis an opportunity for radical surgical resection. We aim to evaluate the short- and long-term efficacy and describe the surgical details of this technique.

Background: Osteosarcoma (OS), the most prevalent primary malignant bone tumor in children and adolescents, arises from bone-forming mesenchymal cells. Despite advancements in surgical resection and neoadjuvant chemotherapy (cisplatin, doxorubicin, and methotrexate), chemotherapy resistance remains a significant challenge, leading to poor survival rates in patients with metastatic or recurrent OS.
Methods: In this study, we focused on the role of OTULIN, a key linear deubiquitinating enzyme, in OS chemoresistance.
