Targeted and immunotherapy drugs for hepatocellular carcinoma (HCC) have been rapidly developed. Atezolizumab in combination with bevacizumab has been recommended as the first-line standard of care for unresectable or advanced HCC in several national and international guidelines. The combination therapies with sindilizumab and bevacizumab biosimilar, apatinib and carrilizumab, dulvalizumab and tremelimumab are also recommended as first-line standard regimens for advanced HCC in the guideline of Chinese Society of Clinical Oncology. Local therapy combined with targeted drugs (such as sorafenib and lenvatinib) or immune checkpoint inhibitors can significantly improve outcomes. Therefore, some progress has also been made in the study of single-agent or combination regimens as perioperative neoadjuvant therapy.

BACKGROUNDWhat benefits and toxicities patients acquire from the use of bevacizumab combined with firstline chemotherapy remains controversial. This study was performed to evaluate the efficacy and safety of first-line chemotherapy plus bevacizumab in patients with metastatic colorectal cancer (mCRC).

METHODSSeveral databases, including PubMed, Embase, and Cochrane Library, were searched up to April 30, 2013. Eligible studies were only randomized, controlled trials (RCTs) with a direct comparison between mCRC patients treated with and without bevacizumab. Overall risk ratio (RR), hazard ratio (HR), odds ratio (OR), and 95% confidence intervals (CI) were calculated employing fixed or random-effects models depending on the heterogeneity of the included trials.

RESULTSSix RCTs, including 1582 patients in chemotherapy plus bevacizumab group and 1484 patients in chemotherapyalone group, were included. Overall, the addition of bevacizumab to first-line chemotherapy increased overall response rate (ORR) by 4.5%, prolonged both progression-free survival (PFS) and overall survival (OS), and increased the rate of total Grades 3 or 4 adverse events (G3/4AEs) by 6.9%. Significant differences were found in ORR (RR = 1.22 (95% CI 1.01-1.46), P = 0.03), PFS (HR = 0.60 (95% CI 0.47-0.77), P < 0.0001), OS (HR = 0.83 (95% CI 0.70-0.97), P = 0.02), and any G3/4AEs (OR = 1.56 (95% CI 1.29-1.89), P < 0.00001).

CONCLUSIONBevacizumab is a valuable addition to the current first-line chemotherapy regimens used in patients with mCRC, because of conferring a significant improvement in ORR, PFS, and OS, even though it increased adverse events.

INTRODUCTIONThe aim of this study was to determine the effectiveness of intraocular injections of bevacizumab for neovascularisation of the iris and neovascular glaucoma.

CLINICAL PICTUREThree patients with neovascularisation of the iris due to various causes were recruited.

TREATMENTPatients were treated with intraocular bevacizumab.

OUTCOMENeovascularisation of the iris was noted to have completely regressed as early as 3 days after the injection and in all the patients (100%) within 8 days after injection. They were followed up for at least 1 month with no clinical evidence of recurrence. Visual acuity remained stable or improved, and the intraocular pressure was controlled in all the 3 patients' eyes. Vitreous haemorrhage also cleared. No signs of inflammation or complications were observed.

CONCLUSIONIntraocular injection of bevacizumab is effective and safe for patients with neovascularisation of the iris and neovascular glaucoma with or without vitreous haemorrhage.

OBJECTIVEThis review aims to summarize the progress of current clinical studies in ocular angiogenesis treated with anti-vascular endothelial growth factor (VEGF) therapy and to discuss the benefits and challenges of the treatment.

DATA SOURCESPubmed, Embase and the Cochrane Library were searched with no limitations of language and year of publication.

STUDY SELECTIONClinical trials and case studies presented at medical conferences and published in peer-reviewed literature in the past decade were reviewed.

RESULTSAnti-VEGF agents have manifested great potential and promising outcomes in treating ocular neovascularization, though some of them are still used as off-label drugs. Intravitreal injection of anti-VEGF agents could be accompanied by devastating ocular or systemic complications, and intimate monitoring in both adult and pediatric population are warranted. Future directions should be focused on carrying out more well-designed large-scale controlled trials, promoting sustained duration of action, developing safer and more efficient generation of anti-VEGF agents.

CONCLUSIONSAnti-VEGF treatment has proved to be beneficial in treating both anterior and posterior neovascular ocular diseases. However, more safer and affordable antiangiogenic agencies and regimens are warranted to be explored.

BACKGROUND: The brain is a common metastatic site in patients with non-small cell lung cancer (NSCLC), resulting in a relatively poor prognosis. Systemic therapy with epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) is recommended as the first-line treatment for EGFR -mutated, advanced NSCLC patients. However, intracranial activity varies in different drugs. Thus, brain metastasis (BM) should be considered when choosing the treatment regimens. We conducted this network meta-analysis to explore the optimal first-line therapeutic schedule for advanced EGFR -mutated NSCLC patients with different BM statuses. METHODS: Randomized controlled trials focusing on EGFR-TKIs (alone or in combination) in advanced and EGFR -mutant NSCLC patients, who have not received systematic treatment, were systematically searched up to December 2021. We extracted and analyzed progression-free survival (PFS) and overall survival (OS). A network meta-analysis was performed with the Bayesian statistical model to determine the survival outcomes of all included therapy regimens using the R software. Hazard ratios (HRs) and 95% confidence intervals (CIs) were used to compare intervention measures, and overall rankings of therapies were estimated under the Bayesian framework. RESULTS: This analysis included 17 RCTs with 5077 patients and 12 therapies, including osimertinib + bevacizumab, aumolertinib, osimertinib, afatinib, dacomitinib, standards of care (SoC, including gefitinib, erlotinib, or icotinib), SoC + apatinib, SoC + bevacizumab, SoC + ramucirumab, SoC + pemetrexed based chemotherapy (PbCT), PbCT, and pemetrexed free chemotherapy (PfCT). For patients with BM, SoC + PbCT improved PFS compared with SoC (HR = 0.40, 95% CI: 0.17-0.95), and osimertinib + bevacizumab was most likely to rank first in PFS, with a cumulative probability of 34.5%, followed by aumolertinib, with a cumulative probability of 28.3%. For patients without BM, osimertinib + bevacizumab, osimertinib, aumolertinib, SoC + PbCT, dacomitinib, SoC + ramucirumab, SoC + bevacizumab, and afatinib showed superior efficacy compared with SoC (HR = 0.43, 95% CI: 0.20-0.90; HR = 0.46, 95% CI: 0.31-0.68; HR = 0.51, 95% CI: 0.34-0.77; HR = 0.50, 95% CI: 0.38-0.66; HR = 0.62, 95% CI: 0.43-0.89; HR = 0.64, 95% CI: 0.44-0.94; HR = 0.61, 95% CI: 0.48-0.76; HR = 0.71, 95% CI: 0.50-1.00), PbCT (HR = 0.29, 95% CI: 0.11-0.74; HR = 0.31, 95% CI: 0.15-0.62; HR = 0.34, 95% CI: 0.17-0.69; HR = 0.34, 95% CI: 0.18-0.64; HR = 0.42, 95% CI: 0.21-0.82; HR = 0.43, 95% CI: 0.22-0.87; HR = 0.41, 95% CI: 0.22-0.74; HR = 0.48, 95% CI: 0.31-0.75), and PfCT (HR = 0.14, 95% CI: 0.06-0.32; HR = 0.15, 95% CI: 0.09-0.26; HR = 0.17, 95% CI: 0.09-0.29; HR = 0.16, 95% CI: 0.10-0.26; HR = 0.20, 95% CI: 0.12-0.35; HR = 0.21, 95% CI: 0.12-0.39; HR = 0.20, 95% CI: 0.12-0.31; HR = 0.23, 95% CI: 0.16-0.34) in terms of PFS. And, SoC + apatinib showed relatively superior PFS when compared with PbCT (HR = 0.44, 95% CI: 0.22-0.92) and PfCT (HR = 0.21, 95% CI: 0.12-0.39), but similar PFS to SoC (HR = 0.65, 95% CI: 0.42-1.03). No statistical differences were observed for PFS in patients without BM between PbCT and SoC (HR = 1.49, 95% CI: 0.84-2.64), but both showed favorable PFS when compared with PfCT (PfCT vs. SoC, HR = 3.09, 95% CI: 2.06-4.55; PbCT vs. PfCT, HR = 0.14, 95% CI: 0.06-0.32). For patients without BM, osimertinib + bevacizumab was most likely to rank the first, with cumulative probabilities of 47.1%. For OS, SoC + PbCT was most likely to rank first in patients with and without BM, with cumulative probabilities of 46.8%, and 37.3%, respectively. CONCLUSION Osimertinib + bevacizumab is most likely to rank first in PFS in advanced EGFR -mutated NSCLC patients with or without BM, and SoC + PbCT is most likely to rank first in OS.

Preoperative chemoradiotherapy (CRT) has become an important component of comprehensive treatment for rectal cancer. Although local recurrent risk has been remarkably reduced by CRT, distant metastasis remains the main cause of therapeutic failure. Therefore, more and more studies focused on controlling distant metastasis in order to prolong long-term survival. Recently, CRT has achieved certain progression in rectal cancer: (1)Patients with stage T3 should be classified into specific subgroups to formulate individualized treatment regimen. For stage T3a, it is feasible to perform surgery alone or administrate low intensity preoperative CRT; for stage T3b and T3c, conventional preoperative CRT should be performed in order to reduce the risk of recurrence postoperatively. (2)With regard to combined regimen for chemotherapy, oral capecitabine superiors to intravenous bolus 5-fluorouracil (5-FU) and is comparable to continuous intravenous infusion 5-FU with a better safety. Therefore, capecitabine is recommended for older patients and those with poor tolerance to chemotherapy. Compared to single 5-FU concurrent CRT, addition of oxaliplatin into preoperative CRT may result in a higher survival benefit in Chinese patients. As to the application of irinotecan, bevacizumab or cetuximab, unless there are more evidence to confirm their efficacy and safety from randomized controlled trial, they should not be recommended for adding to preoperative CRT routinely. (3)On the optimization in CRT pattern, the application values of induction chemotherapy before concurrent CRT, consolidation chemotherapy after concurrent CRT, neoadjuvant sandwich CRT, neoadjuvant chemotherapy alone and short-course preoperative radiotherapy remain further exploration. (4)On the treatment strategy for clinical complete response (cCR) after CRT, whether "wait and see" strategy is able to be adopted, it is still a hot topic with controversy.

BACKGROUNDDiabetic macular edema (DME) is a common manifestation of diabetic retinopathy (DR) that forms the main cause of central visual impairment. This study aimed to compare the efficacy and safety of a single intravitreal injection of bevacizumab alone versus bevacizumab combined with triamcinolone acetonide in eyes with diabetic macular edema (DME).

METHODSA total of 40 eyes in 40 Chinese patients (22 male and 18 female) diagnosed with diabetic macular edema were enrolled in this prospective, randomized, consecutive study. Among them, 21 patients in group 1 were treated with intravitreal injection of bevacizumab (1.25 mg/0.05 ml), and the other 19 patients in group 2 accepted intravitreal bavacizumab (1.25 mg/0.05 ml) combined with triamcinolone acetonide (2 mg/0.05 ml). All patients were examined at baseline and followed up at 4, 6 and 12 weeks after the injection. Changes in mean best correct visual acuity (BCVA) using ETDRS chart, central retina thickness (CRT) measured by optical coherence tomography (OCT), and intraocular pressure (IOP) were focused on.

RESULTSIn group 1, mean BCVA improved from (41.76 ± 15.59) letters (baseline) to (56.24 ± 18.56) letters, (52.57 ± 12.31) letters and (48.41 ± 17.90) letters at 4, 6 and 12 weeks post-injection, respectively (P = 0.004, P = 0.011 and P = 0.026, respectively). Mean CRT decreased from (525.76 ± 184.10) µm (baseline) to (270.33 ± 202.67)µm, (303.12 ± 168.43) µm and (402.26 ± 196.21) µm, respectively (P = 0.009, P = 0.016 and P = 0.030, respectively). In group 2, mean BCVA improved from (39.89 ± 12.27) letters (baseline) to (55.31 ± 19.27) letters, (51.25 ± 13.48) letters and (46.97 ± 16.23) letters at 4, 6 and 12 weeks after injection, respectively (P = 0.003, P = 0.010 and P = 0.027, respectively). Mean CRT decreased from (554.50 ± 169.05) µm (baseline) to (292.76 ± 196.05) µm, (323.46 ± 164.05) µm and (426.38 ± 169.05) µm, respectively (P = 0.009, P = 0.014 and P = 0.028, respectively). However, there was no significant difference between these two groups with regard to mean BCVA (F = 1.602, P = 0.216) and CRT (F = 0.412, P = 0.526). At 12 weeks after the injection, 11 of the patients in group 1 and nine patients in group 2 appeared recurrent macular edema and needed repeat injections. There was one patient in group 2 appeared transient intraocular pressure increases.

CONCLUSIONSIntravitreal injection of bevacizumab combined with/without triamcinolone acetonide had a beneficial effect on DME. However, the significant effect was not permanent. Our results showed that no significant differences were detected between intravitreal bevacizumab combined with/without triamcinolone acetonide for the eyes with diabetic macular edema in Chinese patients.
