In recent years, the incidence of primary liver cancer has been increasing, among which hepatocellular carcinoma (HCC) being the most common subtype. The treatment of early HCC is mainly surgery, but most patients are not diagnosed until the late stage of the disease. The treatment methods and effects are very limited and the prognosis is very poor. Although targeted therapy has prolonged the overall survival of patients with HCC, the overall efficacy is unsatisfactory. The emergence of immunotherapy has brought new therapeutic prospects for HCC. Immune checkpoint inhibitors, among which programmed death-1/programmed death ligand-1 and cytotoxic T-lymphocyte associated antigen-4 are the representative immunological checkpoints, have attracted more attention. This article will introduce the application of immune checkpoint inhibitors in the treatment of advanced HCC, in order to provide a theoretical basis for the use of immune checkpoint inhibitors in the treatment of advanced HCC.

Methods From May 2009 to April 2010, 42 patients with vertebral body lesions underwent CT guided transpedicular biopsy. The clinical data including the puncture method, pahtological resutls, final diagnosis, and the pucture complications were retrospectively analyzed. Results The total accuracy rate of the puncture was 95.2%(40/42). The accuracy rate of the puncture was 94.3% (33/35) for malignant lesions and 100.0% (7/7) for benign lesions. No complication occurred. Conclusion CT guided transpedicular biopsy is very helpful in diagnosing vertebral body lesions with high accuracy and fewer complications.

ObjectiveTo investigate the prognostic factors for inflammatory breast cancer based on the data from West China Hospital with a relatively large sample. MethodsClinical data of 41 patients with histopathologically confirmed inflammatory breast cancer (IBC) who received treatment at West China Hospital Oncology Center of Sichuan University between January 2009 and December 2014 were collected and analyzed. Log-rank test and Cox regression model were used for statistical analysis. ResultsIn the study, negative estrogen receptor, negative progestrone receptor and positive human epidermal growth factor receptor-2 were identified in 58.5%, 61.0% and 34.2% of the inflammatory breast cancer tissues, respectively. Progress free survival (PFS) were between 2 and 60 months, with a median of 35 months. Univariate analysis showed that Tumor Node Metastasis (TNM) stage (P=0.016) and therapeutic effect (P=0.002) influenced the survival. Multivariate analysis showed that TNM stage (P=0.006), therapeutic effect (P=0.002), and anthracycline-taxane based chemotherapy (P=0.041) were the significant prognostic factors. ConclusionTNM stage is the major prognostic factor for IBC. Preoperative chemotherapy with paclitaxel-epirubicin combination can improve the PFS of IBC. Comprehensive treatment mode with operation is recommended for the treatment of IBC.
Objective To investigate the feasibil ity, safety and operative techniques of percutaneous vertebroplasty (PVP) in treating osteolytic bone metastasis of cervical vertebra and reconstructing the function of cervical vertebra. Methods From March 2005 to December 2007, 10 patients with osteolytic bone metastatic carcinoma in single cervical vertebral body received PVP, including 5 males and 5 females aged 38-75 years (mean 54.5 years). Among them, 5 patients had primary lung tumor, 1 primary renal tumor, 1 primary breast tumor, 1 primary cervical tumor and 2 unknown primary lesion. The course of disease was 2-4 years. All the patients suffered from obviously cervical pain and l imitation of activity, including 4 cases of metastatic tumor of the C2 vertebral body, 2 of C3, 2 of C6 and 2 of C7. The general condition of patients was stable before operation, and no blood coagulation dysfunction, radiculalgia and spinal cord compression were detected. Lateral PVP was performed on 6 cases, approaching between the vertebral artery and the carotid sheath under CT guidance and anterolateral PVP was performed on the rest 4 cases, approaching between the trachea and the internal carotid artery under continuously X-ray fluoroscopy. The amount of bone cement injected was 3-4 mL, and the fill ing rate was 50%-100%. Results Without obvious bleeding or organ injury, the puncture was performed successfully on all the patients. Without symptom of spinal cord compression, patients suffered from pain during operation (1 case) and such compl ications noted by immediate CT or X-rays examination after operation as paravertebral epidural cement leakage (2 ases),transverse foramen cement leakage (1 case) and pinhole reflux (3 cases). The pain of patients was improved to various degree postoperatively, the visual analogue scales score was (5.9 ± 1.2) points before operation, which was changed to (2.6 ± 1.2) points at 1 hour after PVP and (1.6 ± 1.3) points at 1 week after PVP, indicating there was a significant difference between pre- and postoperation (P lt; 0.05). During the regular follow-up at 1 week, 3 and 12 months after PVP, all patients had no dislocation of cervical vertebra body, spinal cord compression and paralysis. Five patients died from multiple organ failure due to primary tumor progression, including 3 cases at 6 months after PVP and 2 at 12 months after PVP, and the rest 5 patients’ cervical pain were under control, with sound functional recovery. Conclusion PVP can rel ieve pain quickly and reinforce the stabil ity of the vertebral body, and has sl ight compl ications; the lateral approach is safe and effective.
