By definition, adjuvant oncologic therapy refers to the postsurgical treatment of patients who are at high risk for recurrence but lack measurable disease. Adjuvant radiotherapy is considered a standard of care in a number of cancer types, including tumors of the breast, brain, head and neck, stomach, rectum, cervix, and endometrium, among others. In these cases, adjuvant radiation has been dem...

BACKGROUND Survival from gastric cancer remains poor, particularly in Western populations. Previous pre-clinical and subgroup analyses of clinical trials have suggested differing benefits from fluoropyrimidine-based chemotherapeutics for diffuse and intestinal gastric cancer. This analysis examines patterns of relapse with and without adjuvant chemotherapy after curative resection for gastric c...

Peri-operative chemotherapy has been proposed to improve the survival of patients with colorectal cancer hepatic metastases (CRCHM). However, the role of the adjuvant chemotherapy post-metastasectomy for CRCHM patients who have undergone pre-operative chemotherapy is still undetermined. We retrospectively analyzed the role of adjuvant chemotherapy post-metastasectomy on relapse-free survival (R...

BACKGROUND The EORTC-STBSG coordinated two large trials of adjuvant chemotherapy (CT) in localized high-grade soft tissue sarcoma (STS). Both studies failed to demonstrate any benefit on overall survival (OS). The aim of the analysis of these two trials was to identify subgroups of patients who may benefit from adjuvant CT. PATIENTS AND METHODS Individual patient data from two EORTC trials co...

Renal glomerular lesions were induced by rabbit serum containing antibody to rat collagen injected intravenously into rats prepared with subcutaneously administered Freund adjuvant. Neither the anti-collagen serum nor the adjuvant alone induced the lesion. The lesions were characterized by diffuse glomerular injury with swelling, shredding, and fusion of the basement membranes, crescent formati...

Osteosarcoma is a tumour characterized by the production of osteoid by malignant cells. The incidence is approximately 1 to 3 million/year. The incidence is slightly higher in males. Onset can occur at any age; however, primary high grade osteosarcoma usually occurs in the second decade of life. Historically patients with osteosarcoma were treated with immediate wide or radical amputation. Desp...

BACKGROUND Ependymoma is the most common glial tumor of the adult spinal cord. Current consensus recommends surgical resection with gross total resection (GTR) whenever possible. We performed a comprehensive review of the literature to evaluate whether adjuvant radiotherapy after subtotal resection (STR) has any benefit. METHODS A PubMed search was performed to identify adult patients with sp...

BACKGROUND Evidence from randomized controlled trials (RCTs) has shown a significant survival advantage of trastuzumab. Although extant work in developed countries examined economic evaluation of trastuzumab in adjuvant treatment for early breast cancer based on the 1-year treatment, there is uncertainty about cost-effectiveness of trastuzumab in the Adjuvant Treatment of early breast cancer in...

BACKGROUND Controversy persists as regards the indications and results of surgery in the treatment of patients with stage pIIIA-N2 non-small cell lung cancer (NSCLC). The objective of this study was to analyze the overall survival of a multicentre series of these patients and the role of adjuvant treatment, looking for factors that may define subgroups of patients with an increased benefit from...

Although adjuvant chemoradiotherapy has been an important part in the treatment of gastric cancer, whether or not adjuvant radiation can benefit patients undergoing resection with D2 lymph node dissection remains controversial. This retrospective study aimed to evaluate the role of adjuvant chemoradiotherapy on patients with D2-resected gastric cancer. A total of 337 patients with resected gast...
