Review
In the recent years, a number of targeted therapies have been approved for first-line treatment of patients with metastatic renal cell carcinoma. A systematic review was conducted to assess the clinical efficacy, safety and effect of all first-line treatments evaluated to date on health-related quality of life (HRQoL). A systematic search of Embase, Cochrane and MEDLINE databases was performed to identify randomized controlled trials (1980-2015) evaluating any targeted therapy/immunotherapy against placebo or any other targeted intervention/immunotherapy in treatment-naive patients with metastatic renal cell carcinoma. Conference proceedings from major cancer congresses (2007-2015) were handsearched. Sixteen randomized controlled trials were identified, mostly phase III. Overall, targeted therapies were associated with either improved [sunitinib, bevacizumab+interferon α (IFNα) and temsirolimus] or comparable (sorafenib) progression-free survival (PFS) versus IFNα monotherapy. Sunitinib demonstrated comparable PFS and overall survival to pazopanib, comparable PFS to sorafenib and shorter PFS compared with bevacizumab+IFNα (although no conclusions were made with regard to superiority/inferiority). Compared with sorafenib, tivozanib demonstrated a significantly longer PFS, and both tivozanib and axitinib demonstrated higher response rates. Nintedanib demonstrated comparable PFS and overall survival to sunitinib in a phase II trial. Temsirolimus, sunitinib and sorafenib treatment led to better HRQoL versus IFNα; pazopanib was associated with better HRQoL versus sunitinib. No direct meta-analyses or indirect treatment comparison analysis were undertaken because of noncomparability of the trials. In general, targeted therapies demonstrated favourable clinical efficacy and improved HRQoL compared with IFNα monotherapy. The newer therapies, tivozanib and axitinib (but not nintedanib), appeared to exhibit greater clinical benefit (response rate) than older tyrosine kinase inhibitors.

Meta-Analysis Review
OBJECTIVES
To conduct a systematic review and network meta-analysis (NMA) to assess effectiveness of first-line treatments for advanced renal cell carcinoma (RCC).
METHODS
Database searches were conducted to identify randomized controlled trials (RCTs) reporting results for eligible treatments. A fixed-effect Bayesian NMA was conducted to assess the relative effectiveness of treatments, with progression-free survival (PFS) reported as hazard ratios (HRs) and 95% credible intervals (CrIs).
RESULTS
Eleven unique RCTs were suitable for inclusion in the NMA. In the base case, in terms of PFS, sunitinib was superior compared with bevacizumab + IFN-α (HR = 0.79, 95% CrI: 0.64 - 0.96), everolimus (HR = 0.70, 95% CrI: 0.56 - 0.87), sorafenib (HR = 0.56, 95% CrI: 0.40 - 0.77) and temsirolimus + bevacizumab (HR = 0.74, 95% CrI: 0.56 - 0.96). Although, the point values for the mean and median HRs were < 1.0, there was no significant difference in PFS between sunitinib and axitinib, pazopanib or tivozanib. Although sensitivity analyses impacted the results of the NMA, no treatment was significantly more efficacious than sunitinib.
CONCLUSION
Results from this analysis suggest that there is no treatment superior to the current benchmark treatment, sunitinib, in the management of advanced RCC in the first-line setting.

Meta-Analysis
The efficacy of anti-angiogenic agents (AAAs) in epithelial ovarian cancer (EOC) remains unclear. Therefore, we conducted a systematic review and network meta-analysis (NMA) to synthesize evidence of their comparative effectiveness for improving overall survival (OS) among EOC patients. We searched six databases for randomized controlled trials (RCTs) from their inception to February 2021. We performed an NMA with hazard ratios (HRs) and 95%-confidence intervals (CIs) to evaluate comparative effectiveness among different AAAs in chemotherapy-naïve and recurrent EOC. P-score was used to provide an effectiveness hierarchy ranking. Sensitivity NMA was carried out by focusing on studies that reported high-risk chemotherapy-naïve, platinum-resistant, and platinum-sensitive EOC. The primary outcome was OS. We identified 23 RCTs that assessed the effectiveness of AAAs. In recurrent EOC, concurrent use of trebananib (10 mg/kg) with chemotherapy was likely to be the best option (P-score: 0.88, HR 1.67, 95% CI 0.94; 2.94). The NMA indicated that bevacizumab plus chemotherapy followed by maintenance bevacizumab (P-score: 0.99) and pazopanib combined with chemotherapy (P-score: 0.79) both had the highest probability of being the best intervention for improving OS in high-risk chemotherapy-naïve and platinum-resistant EOC, respectively. AAAs may not play a significant clinical role in non-high-risk chemotherapy-naïve and platinum-sensitive EOC.

BACKGROUND
There are a variety of treatment options for recurrent platinum-resistant ovarian cancer, and the optimal specific treatment still remains to be determined. Therefore, this Bayesian network meta-analysis was conducted to investigate the optimal treatment options for recurrent platinum-resistant ovarian cancer.
METHODS
Pubmed, Cochrane, Embase, and Web of Science were searched for articles published until 15 June 2022. The outcome measures for this meta-analysis were overall survival (OS), progression-free survival (PFS), and adverse events (AEs) of Grade 3-4. The Cochrane assessment tool for risk of bias was used to evaluate the risk of bias of the included original studies. The Bayesian network meta-analysis was conducted. This study was registered on PROSPERO (CRD42022347273).
RESULTS
Our systematic review included 11 RCTs involving 1871 patients and 11 treatments other than chemotherapy. The results of meta-analysis showed that the overall survival (OS) was the highest in adavosertib + gemcitabine compared with conventional chemotherapy, (HR=0.56,95%CI:0.35-0.91), followed by sorafenib + topotecan (HR=0.65, 95%CI:0.45-0.93). In addition, Adavosertib + Gemcitabine regimen had the highest PFS (HR=0.55,95%CI:0.34-0.88), followed by Bevacizumab + Gemcitabine regimen (HR=0.48,95%CI:0.38-0.60) and the immunotherapy of nivolumab was the safest (HR=0.164,95%CI:0.312-0.871) with least adverse events of Grades 3-4.
CONCLUSIONS
The results of this study indicated that Adavosertib (WEE1 kinase-inhibitor) + gemcitabine regimen and Bevacizumab + Gemcitabine regimen would be significantly beneficial to patients with recurrent platinum-resistant ovarian cancer, and could be preferred for recurrent platinum-resistant ovarian cancer. The immunotherapeutic agent, Nivolumab, is of considerable safety, with a low risk for grade-III or IV adverse events. Its safety is comparable to Adavosertib + gemcitabine regimen. Pazopanib + Paclitaxel (weekly regimen), Sorafenib + Topotecan/Nivolumab could be selected if there are contraindications of the above strategies.

Pazopanib is a protein tyrosine kinase inhibitor that limits tumor growth through angiogenesis inhibition. The use of other protein tyrosine kinase inhibitors, specifically sunitinib, within non-clear cell renal cell carcinoma (nccRCC) has led to increased survival with a decreased adverse event profile. The data for the treatment of nccRCC is limited, with most studies evaluating the use of sunitinib. Therefore, the evaluation of pazopanib is of particular clinical interest in the treatment of nccRCC. The objective of this systematic review was to assess the efficacy and safety of pazopanib for nccRCC. PubMed (1946 to April 2019) and Embase (1947 to April 2019) were queried using the search term combination: protein tyrosine kinase inhibitor or pazopanib and non clear cell renal cell carcinoma or non-clear cell renal cell carcinoma. Studies evaluating clinical outcomes of pazopanib for nccRCC were included, represented by 3 retrospective cohort studies and 1 single-arm, open-label prospective study. In patients with advanced or metastatic nccRCC, treatment with pazopanib resulted in positive effects for multiple markers of efficacy, including progression-free survival, overall survival, and objective response rates. The median duration of follow-up ranged from 11.8 months to 24.4 months. Pazopanib was well-tolerated in most studies. The most commonly reported adverse events were fatigue, diarrhea, and hypertension. Pazopanib appears to be an effective and safe option for the treatment of advanced or metastatic nccRCC. Future investigation with larger randomized controlled trials is warranted to further define the role of pazopanib in patients with nccRCC.

Review
A systematic review was conducted to illustrate the bleeding risks associated with targeted therapies used in the treatment of metastatic renal cell carcinoma (mRCC). Eligible studies included phase II, III, or IV clinical trials using pazopanib, sunitinib, cabozantinib, lenvatinib, everolimus, temsirolimus, bevacizumab, axitinib, and/or sorafenib in the setting of mRCC. Types of bleeding event(s), bleeding event frequency, and incidence of thrombocytopenia were collected from the relevant articles. ClinicalTrials.gov was also searched for incidence of "Serious bleeding adverse effects" reported in these trials. The incidences of bleeding events ranged from 1 to 36%, and incidences of thrombocytopenia ranged from 2 to 78%. Available serious bleeding adverse events ranged from 1 to 7%. The highest percentage of bleeding incidences were seen with bevacizumab, while the lowest percentage of bleeding incidences were seen with axitinib. All of the included trials were of high quality per Jadad scoring.

Pyoderma gangrenosum is a rare ulcerative dermatosis. It may be caused by some drugs, including small molecule tyrosine kinase inhibitors (TKIs). The aim of this study was to evaluate the reported evidence of pyoderma gangrenosum associated with the use of these drugs. A systematic electronic literature search of PubMed and Embase was conducted. In these databases, search terms describing pyoderma gangrenosum were combined with TKIs. Fifteen case reports (eight cases associated with sunitinib, two with imatinib, two with ibrutinib, one with gefitinib, one with pazopanib, and one with dabrafenib and trametinib) were identified over the 14 years. The average Naranjo score of these cases is 6.6, which indicates a probable adverse drug reaction. Pyoderma gangrenosum is a probable and reversible drug reaction associated with some TKIs. Detailed medical history can help to prompt diagnosis of drug-induced pyoderma gangrenosum. Clinicians should be aware of TKI-associated pyoderma gangrenosum when caring for the skin of oncologic patients undergoing therapy with kinase inhibitors.

Meta-Analysis Review
PURPOSE
Vascular endothelial growth factor signaling pathway plays a crucial role in angiogenesis and has become a promising target for cancer drug development. We aimed to quantify the overall efficacy and safety of angiogenesis inhibitors in advanced non-small cell lung cancer (NSCLC).
METHODS
Electronic databases were searched for randomized controlled trials (RCTs) comparing angiogenesis inhibitors with non-angiogenesis inhibitors for NSCLC patients. The extracted data on objective response rates (ORRs), disease control rates (DCRs), progression-free survival (PFS) and overall survival (OS) were pooled. Common adverse events (AEs) were also studied.
RESULTS
A total of 33 RCTs involving 17,396 patients were included. Compared with non-angiogenesis inhibitors, angiogenesis inhibitors resulted in significant improvement in PFS (HR, 0.81; 95 % CI 0.76-0.85; p < 0.001), OS (HR, 0.95; 95 % CI 0.92-0.98; p = 0.004), ORR (RR, 1.54; 95 % CI 1.37-1.73; p < 0.001) and DCR (RR, 1.18; 95 % CI 1.10-1.27; p < 0.001). The AEs associated with angiogenesis inhibitors were generally predictable and manageable.
CONCLUSION
Angiogenesis inhibitors were superior to non-angiogenesis inhibitors in terms of ORR, DCR, PFS and OS in advanced NSCLC patients. Further studies are warranted to explore the predictive biomarkers to pick up those who may gain utmost benefit from anti-angiogenic therapy.

Meta-Analysis Review
BACKGROUND
Hyponatraemia has been reported with targeted therapies in cancer patients. Aim of the study was to perform an up-to-date meta-analysis in order to determine the incidence and relative risk (RR) in cancer patients treated with these agents.
MATERIALS AND METHODS
The scientific literature regarding hyponatraemia was extensively reviewed using MEDLINE, PubMed, Embase and Cochrane databases. Eligible studies were selected according to PRISMA statement. Summary incidence, RR, and 95% Confidence Intervals were calculated using random-effects or fixed-effects models based on the heterogeneity of selected studies.
RESULTS
4803 potentially relevant trials were identified: of them, 13 randomized phase III studies were included in this meta-analysis. 6670 patients treated with 8 targeted agents were included: 2574 patients had hepatocellular carcinoma, whilst 4096 had other malignancies. The highest incidences of all-grade hyponatraemia were observed with the combination of brivanib and cetuximab (63.4) and pazopanib (31.7), while the lowest incidence was reported by afatinib (1.7). The highest incidence of high-grade hyponatraemia was reported by cetuximab (34.8), while the lowest incidences were reported by gefitinib (1.0). Summary RR of developing all-grade and high-grade hyponatraemia with targeted agents was 1.36 and 1.52, respectively. The highest RRs of all-grade and high-grade hyponatraemia were associated with brivanib (6.5 and 5.2, respectively). Grouping by drug category, the RR of high-grade hyponatraemia with angiogenesis inhibitors was 2.69 compared to anti-Epidermal Growth Factor Receptors agents (1.12).
CONCLUSION
Treatment with biological therapy in cancer patients is associated with a significant increased risk of hyponatraemia, therefore frequent clinical monitoring should be emphasized when managing targeted agents.

Meta-Analysis Review
We performed a systematic review and meta-analysis of thyroid function abnormalities associated with seven vascular endothelial growth factor receptor (VEGFR) targeted tyrosine kinase inhibitors (sorafenib, sunitinib, axitinib, cediranib, pazopanib, regorafenib and vandetanib). Eligible studies included randomized Phase II and III trials of patients with solid tumors on sorafenib OR sunitinib OR axitinib OR cediranib OR pazopanib OR regorafenib OR vandetanib; describing events of hypothyroidism or hyperthyroidism. Our search strategy yielded 195 potentially relevant citations on the seven agents from Pubmed/Medline, CENTRAL Cochrane registry and ASCO meeting library. After exclusion of ineligible studies, a total of 12 clinical trials were considered eligible for the meta-analysis, including six sunitinib studies, four cediranib studies and two axitinib studies. Patients treated with these agents had a significantly increased risk of all-grade hypothyroidism and the relative risk (RR) of all-grade hypothyroidism was 3.59 (95% CI = 2.40-5.38, p ≤ 0.0001). Exploratory subgroup analysis showed no effect of tumor types or agent used on the RR of hypothyroidism. Our meta-analysis has demonstrated that these three agents are associated with a significantly increased risk of all-grade hypothyroidism; with no difference - on subgroup analysis - between sunitinib and cediranib. Clinicians should be aware of these risks and perform regular thyroid function monitoring.
