Primary liver cancer (hereinafter referred to as liver cancer) is the fourth most common cancer and second leading cause of cancer-related deaths of China. Hepatocellular carcinoma (HCC) accounts for 75% to 85% of liver cancers, more than half of patients with HCC present at an advanced stage where surgery is not suitable. Conversion therapy can provide the opportunity for some unresectable patients to realize surgical resection. With the progress of non-surgical treatments for liver cancer, increased emphasis on comprehensive treatment approaches, and continuous clinical research outcome, conversion therapy of liver cancer has become a common clinical pathway in treatment practice in our country. This paper summarizes the progress in research on conversion therapy for HCC, analyzing its methods, efficacy, safety, and timing of surgery, to provide insights for the clinical practice and research of conversion treatment in HCC.
Objective To discuss the short-term effectiveness of total hip arthroplasty (THA) for post-traumatic osteoarthritis secondary to acetabular fracture. Methods Between January 2004 and March 2012, the clinical data was analyzed retrospectively from 12 cases (13 hips) of post-traumatic osteoarthritis secondary to acetabular fracture undergoing THA. Of 12 patients, 6 were male and 6 were female, with an average age of 55.6 years (range, 40-68 years). The locations were the left hip in 5 cases, the right hip in 6 cases, and bilateral hips in 1 case. The interval between acetabular fracture and THA was 65.7 months on average (range, 12-240 months). The preoperative hip Harris score was 48.8 ± 9.5. Results The incisions healed by first intention. No deep vein thrombosis and infection occurred postoperatively. Ten cases were followed up 1-7 years (mean, 4.8 years). The hip Harris score was 86.5 ± 8.6 at last follow-up, showing significant difference when compared with preoperative score (t=10.520, P=0.006). X-ray films showed no acetabular prosthesis instability. Stem subsidence (2 mm) occurred in 1 case, peri-prosthetic osteolysis in 2 cases, and heterotopic ossification in 2 cases (Brooker type I and type II in 1 case, respectively). Conclusion THA has satisfactory short-term effectiveness for post-traumatic osteoarthritis secondary to acetabular fracture. The good effectiveness is based on strict case selection, pathological evaluation, and the proper acetabular reconstruction.
ObjectiveTo explore the safety and feasibility of surgical treatment of simultaneous multiple primary cancer–hepatocellular carcinoma and esophageal squamous cell carcinoma.MethodThe clinical data of one patient with simultaneous multiple primary cancer of hepatocellular carcinoma and esophageal squamous cell carcinoma, who treated in the First Affiliated Hospital of Guangxi Medical University in April 2019 was analyzed retrospectively. ResultsThe patient was diagnosed as hepatocellular carcinoma and esophageal squamous cell carcinoma on admission. After MDT in the hospital, the patient underwent anterior right hepatectomy + cholecystectomy and radical resection of esophageal carcinoma in turn. The procedure of anterior right hepatectomy + cholecystectomy was smooth, the duration of the surgery was 270 min, and the total blood loss was 500 mL, and postoperative pathology showed that hepatocellular carcinoma was in grade Ⅱ. The operation process of radical resection of esophageal cancer was smooth too, the duration of the surgery was 176 min, and the total blood loss was 100 mL, and postoperative pathology showed moderately differentiated squamous cell carcinoma. No related surgical complications occurred after the operation. Thirteen months after the operation of liver cancer and 10 months after the operation of esophageal cancer, the patient was generally in good condition, well wound healing, and no clinical recurrence. The follow-up of the patient was continued.ConclusionIn allusion to simultaneous multiple primary cancers, it is safe and feasible to evaluate the location, pathological stage, and general condition of the patient by combining multi-disciplinary diagnosis and treatment and then performing radical operations in turn.
