Background Our pilot study describes our initial experience to do a laser resection of lung metastases under video-assisted thoracoscopic control via a minithoracotomy. With this approach, if needed, mediastinal lymphadenectomy is also possible. Methods In this study, 15 patients (11 men and 4 women, mean age: 60 years) with resectable lung metastases of different solid primary tumors (colorectal cancer in seven patients, melanoma in three patients, renal cell carcinoma in two patients, and one each with oropharyngeal cancer, breast cancer, and seminoma) were included...

Simultaneous laparoscopy-assisted resection for synchronous stomach and colon cancers has been reported frequently; however, robot-assisted gastrectomy and colectomy for these conditions are rarely reported. We report the successful use of robotic surgery for synchronous cancers of the stomach and colon. A 71-year-old woman with no specific medical history was diagnosed with early gastric cancer at the gastric angle and right colon cancer after undergoing esophagogastroduodenoscopy and colonofiberoscopy. Abdomino-pelvic computed tomography revealed that the stomach and colon lesions were limited to the mucosa without any lymph nodes or distant metastasis, which suggested the clinical stage for both cancers as T1N0M0...

Pancreatic cancer is the fourth leading cause of cancer-related death. Early detection is challenging because symptoms are relatively nonspecific. Imaging is vital in detecting and staging pancreatic tumors, and management depends on imaging findings. Radiologists should be aware of current surgical treatments for pancreatic neoplasms, as surgeons rely on interpretation of cross-sectional imaging for presurgical planning. Understanding postsurgical anatomy is critical to assess for complications and recurrence...

BACKGROUND: Patients with destructive acetabular lesions are at high risk for morbidity. Harrington described reinforcing acetabular diseased bone with methylmethacrylate, supplemented by metal fixation, to allow total hip reconstruction. However, all published studies using this technique report dislocations. We believe that initial use of constrained liners would help alleviate dislocation risk, without increasing component loosening or polyethylene wear. METHODS: Sixty-eight patients who underwent Harrington hip arthroplasties for metastatic cancer from August 2005 to March 2015 were identified...

INTRODUCTION: A single-center nonrandomized clinical trial was performed to assess the safety and efficacy of IRE ablation of liver tumors in humans. METHODS: 38 malignant liver tumors on 30 patients were treated with IRE between September 2011 and September 2014. Treatment was with curative intent, and the diagnoses were colorectal cancer with liver metastases (CRLM) (n = 23), hepatocellular carcinoma (HCC) (n = 8) and other metastasis (n = 7). Patients were selected when surgery, radiofrequency ablation (RFA) or microwave ablation (MWA) was not an option, and when they met inclusion criteria (tumor size < 3 cm, 1-2 tumors)...

BACKGROUND: Osteosarcoma (OS) is the most common primary bone tumor in both humans and dogs and is the second leading cause of cancer related deaths in children and young adults. Limb sparing surgery along with chemotherapy has been the mainstay of treatment for OS. Many patients are not cured with current therapies, presenting a real need for developing new treatments. Histone deacetylase (HDAC) inhibitors are a promising new class of anticancer agents. In this study, we investigated the activity of the novel HDAC inhibitor AR-42 in a panel of human and canine OS cell lines...

: Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with the 5-year survival rate less than 6%. Previous results indicated that serum levels of CA125 (encoded by MUC16) could be used to predict which groups of pancreatic cancer patients may benefit from surgery. However, the underlying mechanism remains elusive. Herein, using the Cancer Genome Atlas and clinicopathologic data obtained from our center, we demonstrate that high CA125 serum levels and expression levels of MUC16 are predictive of poor prognosis...

Melanoma is the third highest rated cancer in prevalence. Surgery, radiotherapy and targeted/biological therapies in addition to chemotherapy are available options for management of this cancer. Met is an appealing target for management of this type of cancer, since it targets many cancer vital processors, such as angiogenesis, cell growth, scattering and differentiation. In this review, we provide an overview about pathway abnormalities associated with melanoma. We also provide a summary about the events involved in Met signaling and related signaling molecules...

Hepatobiliary and pancreatic (HBP) cancers are associated with high cancer-related death rates. Surgery aiming for complete tumor resection (R0) remains the cornerstone of the treatment for HBP cancers. The current progress in the adjuvant treatment is quite slow, with gemcitabine chemotherapy available only for pancreatic ductal adenocarcinoma (PDA). In the advanced and metastatic setting, only two targeted drugs have been approved by the Food & Drug Administration (FDA), which are sorafenib for hepatocellular carcinoma and erlotinib for PDA...
