Short-term and Long-term Efficacy Evaluation of Drug-Loaded Osteoset Artificial Bone Grafting Fusion in the Treatment of Sacroiliac Joint Tuberculosis.

Objective: To analyze the short-term and long-term efficacy of Osteoset artificial bone graft fusion mixed with rifampicin for injection in the treatment of sacroiliac joint tuberculosis. Methods: A retrospective analysis was carried out on 70 patients diagnosed with sacroiliac joint tuberculosis who were admitted and underwent surgical treatment in our orthopedics department between April 2014 and May 2020. The patients were divided into three groups based on the different bone graft materials used: autogenous bone graft group (25 cases), simple lesion removal group (18 cases), and drug-loaded calcium sulfate bone graft group (27 cases). General information and surgical details of the three groups were compared. Sacroiliac X-ray and CT scans were performed at regular intervals to record pre- and post-treatment erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, bone graft fusion rates at 6, 12, and 18 months post-surgery, Majeed score for functional evaluation, and postoperative complications. Results: There was no statistically significant difference in operation time, intraoperative bleeding, and intraoperative pus removal volume among the three groups of patients (P > .05). Postoperatively, 70 patients were followed up, and the serum levels of ESR and CRP in all three groups of patients were significantly reduced at 3 months after surgery (P < .05). In the autogenous bone graft group, the bone graft fusion rates were 24.00% (6/25) at 6 months postoperatively, 76.00% (18/25) at 12 months, and 96.00% (24/25) at 18 months. In the simple lesion removal group, the bone graft fusion rates were 16.67% (3/18) at 6 months postoperatively, 27.78% (5/18) at 12 months, and 55.56% (10/18) at 18 months. In the drug-loaded calcium sulfate bone graft group, the bone graft fusion rates were 18.52% (5/27) at 6 months postoperatively, 55.56% (15/27) at 12 months, and 81.48% (22/27) at 18 months. In the autogenous bone graft group, the postoperative Majeed score averaged (91.47±4.13) points, with 13 cases rated as excellent and 10 cases rated as good, resulting in an excellent and good rate of 92.00% (23/25). The Majeed scores at 6, 12, and 18 months postoperatively were (67.19±4.22) points, (80.28±5.83) points, and (91.47±4.13) points, respectively. Among them, there were 4 excellent and 3 good cases at 6 months postoperatively, with an excellent and good rate of 28.00% (7/25). At 12 months postoperatively, there were 8 excellent and 10 good cases, with an excellent and good rate of 72.00% (18/25). At 18 months postoperatively, there were 13 excellent and 10 good cases, with an excellent and good rate of 92.00% (23/25). In the simple lesion removal group, the Majeed scores at 6, 12, and 18 months postoperatively were (59.17±3.95) points, (69.84±5.16) points, and (76.22±8.76) points, respectively. There were 2 excellent and 2 good cases at 6 months postoperatively, with an excellent and good rate of 22.22% (4/18). At 12 months postoperatively, there were 4 excellent and 3 good cases, with an excellent and good rate of 38.89% (7/18). At 18 months postoperatively, there were 5 excellent and 5 good cases, with an excellent and good rate of 55.56% (10/18). In the drug-loaded calcium sulfate bone graft group, the Majeed scores at 6, 12, and 18 months postoperatively were (63.24±4.17) points, (77.39±5.50) points, and (86.64±7.03) points, respectively. There were 3 excellent and 3 good cases at 6 months postoperatively, with an excellent and good rate of 22.22% (6/27). At 12 months postoperatively, there were 9 excellent and 7 good cases, with an excellent and good rate of 59.26% (16/27). At 18 months postoperatively, there were 10 excellent and 12 good cases, with an excellent and good rate of 81.48% (22/27). The Majeed scores for all three groups of patients showed a significant increase in the three follow-up evaluations compared to pre-treatment (P < .05). Conclusion: Drug-loaded Osteoset artificial bone graft fusion is a safe and effective method for treating bone defects after the debridement of sacroiliac joint tuberculosis lesions. It has fewer postoperative complications and achieves bone graft fusion in a shorter time compared to simple lesion removal methods.

Hyperthermic intrathoracic/intraperitoneal chemotherapy versus conventional intrapleural/intraperitoneal chemotherapy for the malignant effusion: a multi-center randomized clinical trial.

OBJECTIVE: To compare the efficacy and safety of hyperthermic intrathoracic/intraperitoneal chemotherapy versus conventional intrapleural/intraperitoneal chemotherapy in the treatment of malignant pleural or peritoneal effusion. METHODS: A randomized clinical trial was carried out in 8 cancer centers across China. Patients with malignant pleural or peritoneal effusion were randomly assigned to the study group or control group. Patients in the study group were treated with cisplatin-based hyperthermic intrathoracic chemotherapy (HITHOC) or hyperthermic intraperitoneal chemotherapy (HIPEC), while the control group was treated with conventional intrapleural or intraperitoneal chemotherapy using same chemotherapeutic regime as the study group. The objective response rate (ORR) was analyzed as primary outcome. Quality-of-life (QOL) score was recorded as secondary outcome using the questionnaire 30 (QLQ-C30) of the European Organization for Research and Treatment of Cancer (EORTC). The efficacy and safety of the two treatments were compared. RESULTS: Total 135 patients were recruited and randomized in this study, with 67 patients in the study group and 68 patients in the control group. The ORR in the study group (80.70%) was significantly higher than that in the control group (31.03%, p < 0.001). However, neither changes of QOL scores, nor incidence rates of adverse events were significantly different between the two groups (p = 0.076 and 0.197, respectively). CONCLUSION: Efficacy of HITHOC or HIPEC is superior to that of conventional modality for the treatment of malignant effusion with comparable side effects.

A novel method of bedside hyperthermic intraperitoneal chemotherapy as adjuvant therapy for stage-III gastric cancer.

OBJECTIVE: To investigate the efficacy and safety of a novel method of hyperthermic intraperitoneal chemotherapy (HIPEC) as adjuvant therapy for stage-III gastric cancer. METHODS: Patients with stage-III gastric cancer who underwent D2 radical gastrectomy were randomly assigned to the HIPEC or control group four weeks after surgery. The HIPEC group was treated with cisplatin (60 mg/m2) administered with a HIPEC device on days 1 and 3 (30 mg/m2 each time), along with oral S-1, 40-60 mg, twice daily, for 14 days. The control group was treated with cisplatin (60 mg/m2) administered intravenously plus oral S-1 (40-60 mg, 2/d for 14 days). The primary outcome of the study was disease-free survival (DFS). RESULTS: Total 114 patients were included in the study, with 57 patients in each group. The median DFS was 29.0 months in the HIPEC group, which was significantly longer than that in the control group (15.0 months, p = 0.006). The two-year DFS rate in the HIPEC group was higher than that in the control group (50.4% vs. 25.5%). Median OS was 42.0 month in the HIPEC group and 31.0 month in the control (p = 0.042). Peritoneal metastasis occurred in six patients in the HIPEC group (10.5%) and 12 patients in the control (21.1%, p = 0.198). No significant difference in the incidence of adverse event except for thrombocytopenia. CONCLUSION: HIPEC with cisplatin plus oral S-1 is a safe and effective adjuvant therapy for patients with advanced gastric cancer following D2 radical gastrectomy. Trial registration: This study was registered at ClinicalTrials.gov with the identifier (NCT number): NCT02396498.

Donafenib Versus Sorafenib in First-Line Treatment of Unresectable or Metastatic Hepatocellular Carcinoma: A Randomized, Open-Label, Parallel-Controlled Phase II-III Trial.

PURPOSE: Donafenib, a novel multikinase inhibitor and a deuterated sorafenib derivative, has shown efficacy in phase Ia and Ib hepatocellular carcinoma (HCC) studies. This study compared the efficacy and safety of donafenib versus sorafenib as first-line therapy for advanced HCC. PATIENTS AND METHODS: This open-label, randomized, parallel-controlled, multicenter phase II-III trial enrolled patients with unresectable or metastatic HCC, a Child-Pugh score ≤ 7, and no prior systemic therapy from 37 sites across China. Patients were randomly assigned (1:1) to receive oral donafenib (0.2 g) or sorafenib (0.4 g) twice daily until intolerable toxicity or disease progression. The primary end point was overall survival (OS), tested for noninferiority and superiority. Efficacy was primarily assessed in the full analysis set (FAS), and safety was assessed in all treated patients. RESULTS: Between March 21, 2016, and April 16, 2018, 668 patients (intention-to-treat) were randomly assigned to donafenib and sorafenib treatment arms; the FAS included 328 and 331 patients, respectively. Median OS was significantly longer with donafenib than sorafenib treatment (FAS; 12.1 v 10.3 months; hazard ratio, 0.831; 95% CI, 0.699 to 0.988; P = .0245); donafenib also exhibited superior OS outcomes versus sorafenib in the intention-to-treat population. The median progression-free survival was 3.7 v 3.6 months (P = .0570). The objective response rate was 4.6% v 2.7% (P = .2448), and the disease control rate was 30.8% v 28.7% (FAS; P = .5532). Drug-related grade ≥ 3 adverse events occurred in significantly fewer patients receiving donafenib than sorafenib (125 [38%] v 165 [50%]; P = .0018). CONCLUSION: Donafenib showed superiority over sorafenib in improving OS and has favorable safety and tolerability in Chinese patients with advanced HCC, showing promise as a potential first-line monotherapy for these patients.

Retrospective analysis on the safety of 5,759 times of bedside hyperthermic intra-peritoneal or intra-pleural chemotherapy (HIPEC).

The current study was designed to analyze safety of the bedside hyperthermic intra-pleural or intra-peritoneal chemotherapy (HIPEC) from September 2007 to July 2015. Total of 5,759 times of bedside HIPEC in 985 cases of malignant pleural or peritoneal carcinomatosis were analyzed. Of them, 1,510 times was given to 315 cases of malignant pleural effusion, while 4,249 times was performed in 402 patients with malignant ascites and 268 patients without ascites (total 670 patients for peritoneal carcinomatosis). In average, patients with pleural effusion was given 5 times bedside HIPEC and stayed in the hospital for 6.7 days; while patients with peritoneal carcinomatosis was given 6 times of HIPEC and stayed in the hospital for 6.5 days. Overall HIPEC-associated mortality was zero. Overall HIPEC-associated incidence of side effect in the intra-pleural HIPEC was 2.0%. Specifically, 0.6% was pneumothorax, 0.3% was cytotoxic agent-induced pleural inflammation, 0.5% was pain at puncture location, and 0.3% was failure of HIPEC procedure. Overall HIPEC-associated incidence of side effect in the intra-peritoneal HIPEC was 2.4%, i.e., failure of HIPEC procedure in 1.3%, pain at puncture location was 0.5%, cytotoxic agent-induced peritoneal inflammation was 0.1%, intestinal obstruction was 0.1% and intestinal perforation was 0.07%. These findings indicated that bedside HIPEC applied in the current study is safe to be performed by a Physician or Oncologist under local anesthesia at a patient's bedside. The procedure is easy to perform and well-tolerated by the patients with late stage cancer or post-surgery recurrent cancer.

[TREATING SACROILIAC JOINT TUBERCULOSIS WITH RIFAMPICIN-LOADED OsteoSet].

OBJECTIVE: To assess the safety, feasibility, and effectiveness of medical calcium sulfate (OsteoSet) mixed with powder for injection of rifampicin after radical debridement in the treatment of sacroiliac joint tuberculosis. METHODS: A retrospective analysis was made on the clinical data from 27 patients with sacroiliac joint tuberculosis who underwent debridement surgery and local bone graft of OsteoSet artificial bone impregnated with powder for injection of rifampicin between August 2006 and August 2010. There were 10 males and 17 females with an average age of 35.2 years (range, 16-64 years). The mean disease duration was 7.5 months (range, 1.5-16 months). The left sacroiliac joint was involved in 16 cases, the right side in 10 cases, and both sides in 1 case; Of them, 18 cases had iliac fossa abscess and 6 cases of buttocks abscess. According to the classification system by Kim, there were 9 cases of type III and 18 cases of type IV. The preoperative Majeed score was 61.23?6.49, including good in 4 patients, general in 19 patients, and poor in 4 patients. RESULTS: All patients achieved wound healing by first intention; no complications of pelvic infection, peripheral nerve injury, and lower extremity deep vein thrombosis occurred. Twenty-six patients were followed up 16 months on average (range, 12-24 months). All the patients had normal sense and movement of both lower limbs; no perineum sensory disturbance was found. One case of multi-drug resistant had local recurrence at 3 months after operation, which was cured after adjusting anti-tuberculosis drugs, nutritional support, enhancing immunity with thymopentin, and second operation. Bone union was observed at 10.5 months on average (range, 9-12 months) in 25 patients, and clinical symptoms disappeared with no recurrence or complication, and they returned to previous work. The Majeed score at last follow-up was 92.31 +/- 3.36, showing significant difference when compared with preoperative score (t = -32.76, P=0.00). The results were excellent in 22 patients, good in 4 patients, and the excellent and good rate was 100%, showing signi.ficant difference compared with the preoperative one (chi2=31.93, P=0.00). CONCLUSION: Bone graft interbody fusion surgery with rifampicin loaded OsteoSet is one of the effective methods to treat sacroiliac joint tuberculosis.
