Efficacy and safety of regorafenib for the treatment of metastatic colorectal cancer in routine clinical practice: results from a Spanish hospital

IntroductionRegorafenib is indicated as treatment in third-line and beyond in patients with metastatic colorectal cancer.Methods This is a retrospective study of a cohort of patients with mCRC treated with regorafenib in Hospital Universitario Ramón y Cajal, in Madrid, Spain.ResultsWith the aim to assess the efficacy and safety of regorafenib, 91 patients treated between 2013 and 2023 were included. Only 1.1% of patients achieved disease control. Median progression free survival was 2.40 months and median overall survival was 4.76 months. The most frequent adverse events were fatigue and hand-foot skin reaction (59.34% and 28.57%, respectively).DiscussionOur results confirm the safety of regorafenib as treatment of mCRC in real clinical practice. Although our population is less pretreated than in the CORRECT trial, our disease control rate was inferior. This difference may be due to a worse baseline status and a high percentage of hepatic disease showed in our patients.

The efficacy and safety of Radiofrequency ablation combined with Lenvatinib plus Sintilimab in Unresectable Hepatocellular Carcinoma: a real-world study

BackgroundThe combination of targeted therapy and immunotherapy has improved the clinical outcomes of unresectable hepatocellular Carcinoma (HCC). However, the overall prognosis remains suboptimal. This study aims to evaluate the efficacy and safety of a novel combination of radiofrequency ablation (RFA) with lenvatinib plus sintilimab in unresectable HCC.MethodsIn this retrospective study, patients diagnosed with unresectable HCC were included and divided into two cohorts: RFA combined with lenvatinib plus sintilimab (R-L-S group) and lenvatinib plus sintilimab (L-S group). The primary efficacy endpoints were objective response rate (ORR) and progression free survival (PFS). Adverse events were analyzed to assess the safety profiles.ResultsThe median follow-up periods for the entire cohort were 14.0 months. The R-L-S group (n = 60) had a significantly higher ORR than those with L-S alone (n = 62) (40.0% vs. 20.9%; p = 0.022). Moreover, patients in the R-L-S group had improved median PFS (12 vs. 8 months; p = 0.013) and median overall survival (24 vs. 18 months; p = 0.037), as compared with lenvatinib and sintilimab alone. No significant difference in treatment related adverse event (TRAE) of any grade between the two groups. The most common TRAEs of grade ≥ 3 were fatigue 10.0% (6/60) and hand-foot skin reaction 10.0% (6/60) in the R-L-S group and hand-foot skin reaction 11.3% (7/62) in the L-S group.ConclusionIn unresectable HCC patients, the incorporation of RFA to lenvatinib plus sintilimab demonstrated improved efficacy without compromising safety compared with lenvatinib plus sintilimab alone.

Enhanced anticancer activity of silver doped zinc oxide magnetic nanocarrier loaded with sorafenib for hepatocellular carcinoma treatment

Drug delivery is the process or method of delivering a pharmacological product to have therapeutic effects on humans or animals. The use of nanoparticles to deliver medications to cells is driving the present surge in interest in improving human health. Green nanodrug delivery methods are based on chemical processes that are acceptable for the environment or that use natural biomaterials such as plant extracts and microorganisms. In this study, zinc oxide-superparamagnetic iron oxide-silver nanocomposite was synthesized via green synthesis method using Fusarium oxysporum fungi mycelia then loaded with sorafenib drug. The synthesized nanocomposites were characterized by UV-visibile spectroscopy, FTIR, TEM and SEM techniques. Sorafenib is a cancer treatment and is also known by its brand name, Nexavar. Sorafenib is the only systemic medication available in the world to treat hepatocellular carcinoma. Sorafenib, like many other chemotherapeutics, has side effects that restrict its effectiveness, including toxicity, nausea, mucositis, hypertension, alopecia, and hand-foot skin reaction. In our study, 40 male albino rats were given a single dose of diethyl nitrosamine (DEN) 60 mg/kg b.wt., followed by carbon tetrachloride 2 ml/kg b.wt. twice a week for one month. The aim of our study is using the zinc oxide-superparamagnetic iron oxide-silver nanocomposite that was synthesized by Fusarium oxysporum fungi mycelia as nanocarrier for enhancement the sorafenib anticancer effect.

Optimizing patient (pt) care through pt-focused resources to prevent and manage hand-foot skin reaction (HFSR).

e24144 Background: Research has shown that pts and caregivers (non-HCPs) seek medical and disease-related information more than once a month, and this has accelerated due to the COVID-19 pandemic. However, they find it difficult to understand the information they receive and thus, can be misinformed. By understanding the use of fair-balanced medical information (MI) resources by non-HCPs, pharmaceutical companies can develop scientifically accurate yet pt-friendly resources to meet their needs (Goettner, 2022; Rai, 2022). Upon reviewing the unsolicited oncology inquiries received by our MI department, approximately 25% of inquiries were from non-HCPs seeking information. Over the past 3 years, non-HCPs have submitted almost 10,000 inquiries regarding our oncology products, in which 191 inquiries were specifically regarding HFSR and regorafenib and sorafenib. Historically, our MI department responded to non-HCP inquiries by sharing the product label information. However, we identified an unmet need for trustworthy, comprehensive, and accurate pt resources in plain language. Methods: A full literature review was performed, and the relevant data were summarized in plain language for pts. Both HCPs and pts participated in developing the global pt resource on the prevention and management of HFSR for regorafenib and sorafenib. The seven-page interactive brochure was written in 4th to 6th grade reading level which included images and graphics to enhance the understanding of data, easy navigation to the content of interest, and glossary to define key terms. Furthermore, these materials were translated for pts who participated in the regorafenib and sorafenib Patient Support Program in Brazil to further educate and support pts who have started therapy. Results: As of June 2023, the global pt medical resource has been deployed 28 times in Brazil, delivering key information to non-HCPs on their disease and treatment while emphasizing its practical utility and addressing health literacy challenges. We collected feedback from pts who utilized the translated material, and they described it to be “informative” and “helpful” since it empowered them to effectively navigate and address HFSR-associated discomforts during their treatment journey. The feedback has also been utilized to further enhance the resource’s feasibility. Conclusions: The pt feedback on the brochures showcases the value of pt-focused approach in oncology and the positive impact of collective efforts across all stakeholders including pts, pharmaceutical MI departments and pt programs. Furthermore, it demonstrates how MI can bridge the gap between pt insights and clinical knowledge by addressing their needs and providing practical and trustworthy tools. Not only does this initiative enhance pt understanding but also empowers pts to take a more active role in their treatment and fosters shared-decision making.

Postoperative adjuvant hepatic arterial infusion chemotherapy combined with donafenib in hepatocellular carcinoma with solitary large tumor and microvascular invasion: A multicenter, prospective, single-arm, phase II trial.

e16227 Background: Hepatocellular carcinoma (HCC) with solitary large tumor (≥ 5 cm) and microvascular invasion (MVI) was associated with high 5-year recurrence rate and poor survival prognosis. Postoperative adjuvant hepatic arterial infusion chemotherapy (HAIC) was found to improve the recurrence-free survival (RFS) with acceptable safety profiles in HCC patients with MVI. However, the prognosis of HCC who received adjuvant HAIC after hepatectomy still remain far from satisfactory. Several studies have shown that the combination of HAIC and tyrosine kinase inhibitors (TKIs) could exhibit a synergistic anticancer effect and improve the survival outcomes of advanced HCC. Thus, the present study was conducted to explore the efficacy and safety of adjuvant HAIC plus the novel multikinase inhibitor donafenib in HCC with solitary tumor ≥ 5 cm and MVI. Methods: This prospective, single-arm phase II study was conducted in three medical centers in China. HCC patients with both solitary tumor ≥ 5 cm and MVI, no evidence of recurrence at radiological follow-up at 4-8 weeks after hepatectomy, no previous treatment for HCC other than hepatectomy, Child-Pugh score A or B7 were enrolled. Eligible patients received one cycle of HAIC with oxaliplatin, fluorouracil, and leucovorin (HAIC-FOLFOX4), and followed by donafenib (200 mg orally twice daily) for up to 1 year until disease recurrence or unacceptable toxicity. The primary endpoint was 1-year recurrence-free survival rate (1-year RFS rate). Secondary endpoints included RFS, overall survival (OS) and safety. Results: A total of 18 patients were included for analysis. The median age was 59 years (range, 28–75), the median maximum tumor size was 7.0 cm (interquartile range [IQR], 6.2–7.8), 88.9% had low-risk MVI, 61.1% had Edmondson-Steiner grade III-IV and 44.4% had incomplete tumour capsule. As of November 27, 2023, 4 of 18 patients (22.2%) recurrenced and no deaths occurred with a median follow-up of 15.0 months (95% confidence interval [CI], 5.1–19.1). The 1-year RFS rate was 64.9% (95%CI, 39.2%–100%), and current immature median RFS was 14.3 months (95%CI, not available [NA], 11.2–NA). The most common treatment-related adverse events (TRAEs) were hand-foot skin reaction (72.2%), diarrhea (38.9%), decreased platelet count (22.2%), hypoalbuminemia (22.2%), and alopecia (22.2%). Grade 3 TRAEs occurred in 6 patients (33.3%), and no grade 4 or 5 TRAEs occurred. Conclusions: In this prospective study, the preliminary data indicated that HAIC combined with donafenib is an encouraging adjuvant therapy with well-tolerated safety profiles for HCC patients with solitary tumor ≥ 5 cm and MVI. Clinical trial information: NCT04962958 .

Efficacy and safety of transarterial therapy combined with donafenib plus immune checkpoint inhibitors for unresectable hepatocellular carcinoma: A multicenter retrospective study.

e16133 Background: Based on the different anti-malignant mechanisms of tyrosine kinase inhibitors (TKIs), immune checkpoint inhibitors (ICIs) and transarterial therapy, several studies have demonstrated the potential of combining these three treatments to improve outcomes in patients with unresectable hepatocellular carcinoma (uHCC). This study aimed to evaluate the efficacy and safety of transarterial therapy plus donafenib and ICIs for uHCC patients in a real-world setting. Methods: This multicenter retrospective study included patients with uHCC who had received at least one cycle of transarterial therapy (hepatic arterial infusion chemotherapy, HAIC, or transarterial chemoembolization, TACE) and donafenib and ICIs (anti-PD-1 available in China) at five cancer centers. Other key inclusion criteria were: (1) no prior systemic treatment; (2) at least one follow-up image data. The primary endpoint was progression-free survival (PFS) according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Secondary endpoints included overall survival (OS), objective response rate (ORR) and toxicity. Results: Of the 61 eligible patients enrolled, 56 (91.8%) were men, 54 (88.5%) had HBV infection, 26 (42.6%) had AFP level > 400 ng/mL, 38 (62.3%) were at BCLC stage C, 32 (52.5%) had macrovascular invasion, 14 (23.0%) had extrahepatic metastasis, 47 (77.0%) had multiple tumors and the median maximum tumor size was 86.0 mm (IQR, 61.5–122.6). Four kinds of ICIs were employed, including tislelizumab (n = 29), camrelizumab (n = 21), sintilimab (n = 9), toripalimab (n = 2). Up to the date of November 24, 2023, the median follow-up time was 13.0 months. The median PFS was 12.7 months (95%CI, 8.4–NA), with a 1-year PFS rate of 52.7% (95%CI, 37.9%–73.1%). The median OS was not reached, and 1-year OS rate was 88.4% (95%CI, 79.9%–97.8%). The ORR according to mRECIST was 70.5%. Twelve (19.7%) patients had received conversion resection, and the median conversion time was 3.1 months (95%CI, 2.37–NA). Overall, 51 (83.6%) patients experienced at least one treatment-related adverse events (TRAEs), 22 (36.1%) had grade 3 or 4 AEs, and no patients died due to AEs. The most common AEs greater than 15% were hand-foot skin reaction (47.5%), liver dysfunction (27.9%), decreased platelet count (19.7%) and hypoalbuminemia (16.4%). Conclusions: This retrospective real-world study showed that transarterial therapy combined with donafenib plus ICIs in the treatment of uHCC patients was well tolerated and comparable clinical efficacy to other triple therapies. This combination strategy may be an appropriate treatment option for uHCC patients.

Single-center retrospective analysis of second-line treatment with regorafenib in patients with advanced colorectal cancer among the COVID-19 pandemic.

e15552 Background: Regorafenib targets multiple tyrosine kinases that has been approved for the third-line treatment in metastatic colorectal cancer (mCRC) patients in China. Here, We retrospectively analyzed the efficacy and safety of regorafenib alone or combined with chemotherapy/immunotherapy in the second-line treatment for those who cannot visit hospital for their chemotherapies because of the COVID-19 pandemic. Methods: Individual patient data from Peking University Third Hospital were analyzed retrospectively from January 2020 to September 2023. The primary endpoint was progression-free survival (PFS), and secondary endpoints were overall survival (OS) and safety. Results: The median age of 31 patients was 65 years, the median PFS was 6 months (1–21 months), and the median OS was 20 months (3–38 months). PFS tended to be prolonged with regorafenib plus capecitabine or immunotherapy in 12 subjects versus regorafenib alone in 19 subjects (8 months vs. 4 months, P = 0.306), with no statistical difference, and so did OS (27 months vs. 15 months, P = 0.899).The analysis of PFS (2.5 months vs. 7 months vs. 4 months, P = 0.164) and OS (13 months vs. 28 months vs. 20 months, p = 0.417) in patients with liver, lung, or abdominal/peritoneal metastases at the initiation of treatment demonstrated poor survival prognosis in patients with liver metastasis. Multivariate analysis showed that regorafenib combined with capecitabine or immunotherapy (wald = 5.766, p = 0.016) and non-liver metastasis (wald = 4.223, p = 0.040) were independent prognostic factors for PFS in the second-line treatment. Adverse drug reactions (ADRs) mainly included hand-foot skin reactions (HFSRs), fatigue, hypertension, and proteinuria, due to which 3 subjects discontinued the treatment. The incidence of Grade 3/4 ADRs was 19.3%, 16.9%, 12.9%, and 9.6%, respectively. Conclusions: Regorafenib alone or combined with chemotherapy/immunotherapy is safe and feasible in the second-line treatment for advanced colorectal cancer, and therefore further prospective studies can be conducted to explore combination therapies.

Adjuvant donafenib for patients with hepatocellular carcinoma at high risk of recurrence following radical resection: A multi-center, retrospective study in China.

e15129 Background: The implementation of adjuvant therapy in reducing tumor recurrence of hepatocellular carcinoma (HCC) is an essential approach for extending the prognosis of patients. The exploration of treatment strategies that are both efficacious and secure remains a prominent area of research in recent years. Donafenib is a novel, oral, small-molecule, multikinase inhibitor, and has demonstrated promising efficacy and safety profiles in preclinical and clinical studies. However, there is currently a lack of reported data on the adjuvant donafenib for HCC following radical resection (R0). The present study aimed to explore the efficacy and safety of adjuvant donafenib for HCC patients at high risk of recurrence following R0. Methods: This retrospective study analyzed 196 patients who underwent R0 for HCC between April 2021 and October 2022. All patients exhibited at least one of the following high risk recurrence factors:① single lesion > 5 cm or multiple lesions of any size; ② microvascular invasion (MVI); and ③ satellite nodules. Among these patients, 49 received donafenib, while 147 (control group) did not. In the donafenib group, donafenib was administered at a dose of 100 or 200 mg bid until tumor recurrence and serious adverse events (AEs). The 1-year and 2-year recurrence-free survival (RFS) rates and overall survival (OS) rates were compared between the two groups, as well as the incidence of adverse events (AEs) in the donafenib group. Inverse probability of treatment weighting (IPTW) was used. Results: The patient population consisted of 167 males and 29 females, with a median age of 59 (range 30-83). All patients exhibited a high risk of recurrence (number of tumors single/multiple, 167/29; tumor size within 5.0/above 5.0 cm, 78/118; MVI yes/no, 140/56; satellite nodules yes/no, 39/157). The median follow-up was 21.8 (range 3.8-32.0) months. Before IPTW, the donafenib group exhibited significantly higher 1-year and 2-year RFS rates compared to the control group (83.7%, 68.0% vs 66.7%, 47,6%, p = 0.023), while no significant difference in 1-year and 2-year OS rates (97.8%, 93.9% vs 91.8%, 80.6%, p = 0.120). After IPTW, the 1-year, 2-year RFS rates and OS rates were more favorable for the donafenib group compared to the control group (86.6%, 72.5% vs 64.8%, 45.0%, P = 0.004; 97.9%, 95.6% vs 89.5%, 77.9%, P = 0.043, respectively). In the donafenib group, AEs occurred in 44 patients, including 39 with grade 1 or 2 AEs and 5 with grade 3 AEs. The most common AEs included hand-foot skin reaction, decreased platelet count, and diarrhea. Conclusions: Adjuvant donafenib may improve RFS of HCC patients at high risk of recurrence following R0, while exhibiting favorable safety. This finding deserves further exploration.

Relationship between hand-foot skin reaction and external force on patients with hepatocellular carcinoma: A cohort study

PurposeHand-foot skin reaction (HFSR), a side effect of tyrosine kinase inhibitor (TKI) treatment, makes it difficult to walk and perform daily activities because of pain in the limbs. HFSR occurs predominantly in the sites where external forces (pressure and shear stress) are applied. This study aimed to determine whether pressure or shear stress induces the occurrence of HFSR. MethodsThis cohort study was conducted in patients who received TKI treatment for hepatocellular carcinoma. The external forces applied to the sole of the patients' foot while walking was measured, and its association with the occurrence of HFSR was examined. The degree of HFSR was assessed by the patient's response during the examination and by photographs of their feet. The patients' feet were divided into low (grade <2) or high (grade ≥2) HFSR foot group, and the differences in external forces between the groups were analyzed using t-test and Cox hazard analysis. ResultsAnalysis of the feet of 55 study participants (n = 110) showed no significant difference between the groups on t-test (p ≥ 0.05), however, Cox hazard analysis showed an increased risk of HFSR with higher peak shear stress values at the fifth metatarsal head (hazard ratio = 1.01, p = 0.047; 95% confidence interval = 1.00–1.02). ConclusionShear stress is possibly related to HFSR occurrence. Nurses should assess whether patients' shoes fit their feet before initiating TKI treatment. They should instruct patients to wear shoes that are fit of both diameter and width for their feet.

Identification of Keratinocyte Cytoprotectants against Toxicity by the Multikinase Inhibitor Sorafenib Using Drug Repositioning

Hand-foot skin reaction (HFSR) is the most common adverse event of multikinase inhibitors (MKI), such as sorafenib. Although HFSR is not life-threatening, severe cases impair quality of life because of pain and reduced activities of daily living. However, the pathological mechanisms of HFSR have not yet been elucidated in detail, and there is currently no effective treatment. We aimed to identify keratinocyte cytoprotectants against sorafenib toxicity.The screening of cytoprotectants against sorafenib toxicity was performed using cultured normal human epidermal keratinocytes (NHEKs) or a reconstructed human epidermis (RHE) model and off-patent approved drugs in the Prestwick Chemical library. Among 1273 drugs in the chemical library, 8 dose-dependently increased cell viability by more than 200% in the presence of sorafenib. In the presence of sorafenib, the number of proliferating cell nuclear antigen- positive cell was significantly higher in clofazimine-, cyclosporin A-, and itraconazole-treated RHE models than in sorafenib-treated models. And, candidate drugs suppressed sorafenib-induced apoptosis in NHEKs. In addition, clofazimine, itraconazole and pyrvinium pamoate significantly recovered the phosphorylation of ERK1/2 in the presence of sorafenib. Collectively, hit drugs promoted cell viability and normalized keratinocyte proliferation in the presence of sorafenib. These candidate drugs have potential as treatments for MKI-induced HFSR.

Selective Internal Radiation Therapy Using Y-90 Resin Microspheres for Metastatic Colorectal Cancer: An Updated Systematic Review and Network Meta-Analysis.

This literature review and exploratory network meta-analysis (NMA) aimed to compare the clinical effectiveness and tolerability of selective internal radiation therapy (SIRT) using yttrium-90 (Y-90) resin microspheres, regorafenib (REG), trifluridine-tipiracil (TFD/TPI), and best supportive care (BSC) in adult patients with chemotherapy-refractory or chemotherapy-intolerant metastatic colorectal cancer (mCRC). In light of recently published data, the literature was searched to complement and update a review published in 2018. Studies up to December 2022 comparing two or more of the treatments and reporting overall survival (OS), progression-free survival (PFS), or incidence of adverse events (AE) were included. The NMA compared hazard ratios (HRs) for OS and PFS using Markov chain Monte Carlo techniques. Fifteen studies were included, with eight studies added (none addressing SIRT). All active treatments improved OS in relation to BSC. SIRT had the longest OS among all treatments, although without statistically significant differences (HR [95% credible interval] for SIRT, 0.48 [0.27, 0.87]; TFD/TPI, 0.62 [0.46, 0.83]; REG, 0.78 [0.57, 1.05]) in a fixed effects model. Information regarding SIRT was insufficient for PFS analysis, and TFD/TPI was the best intervention (HR 2.26 [1.6, 3.18]). One SIRT study reported radioembolization-induced liver disease in > 10% of the sample; this was symptomatically managed. Non-haematological AEs (hand-foot skin reaction, fatigue, diarrhoea, hypertension, rash or desquamation) were more common with REG, while haematological events (neutropoenia, leukopenia, and anaemia) were more common with TFD/TPI. Current evidence supports SIRT treatment in patients with chemotherapy-refractory or chemotherapy-intolerant mCRC compared to newer oral agents, with comparable OS and low incidence of AEs.

Outcomes of patients (pts) with advanced renal cell carcinoma (aRCC) treated with cabozantinib (CABO) after lenvatinib plus pembrolizumab (LEN+PEM).

433 Background: LEN+PEM is an approved first-line therapy for aRCC. In the CLEAR study, it produced a 71% objective response rate (ORR), an 18% complete response rate, and improved progression-free survival (PFS) and overall survival (OS) compared to sunitinib. CABO is approved as second and later line therapy for aRCC. We explored the efficacy of CABO in pts with aRCC after treatment with LEN+PEM. Methods: This is a retrospective study of pts with aRCC who received CABO after LEN+PEM at our institution from 12/2019 to 8/2023. Demographics and clinical data were abstracted from the EMR. A blinded radiologist assessed tumor response using RECIST v1.1. We measured PFS, time on therapy (TOT) and OS from start date of CABO. Results: 22 pts were analyzed (Table 1). Median follow up was 7.7 months (mo); 11 pts received LEN+PEM on the HOPE 111 trial (NCT02501096). Among all 22 pts, 11 (50%) had a partial response (PR), 5 (22.7%) had stable disease (SD), and 6 (27.3%) had progressive disease (PD) on LEN+PEM. Median TOT with LEN+PEM was 7.4 mo (range: 1.8-29). 20 pts (90.9%) discontinued LEN+PEM due to PD, 1 pt (4.5%) due to fatigue, and 1 pt (4.5%) due to elevated liver enzymes. 17 pts received CABO right after LEN+PEM; 3 pts received 1 line and 2 pts received 2 lines of therapy before CABO after LEN+PEM. Of 19 pts with evaluable radiographic response on CABO, 1 pt had a PR (ORR 5.3%, PFS 16.1 mo) and 3 pts had SD for ≥6 mo. Median TOT with CABO was 4.3 mo (range: 0.2-18.2); 13 pts (59.1%) took CABO for ≥4 mo, 7 pts (31.8%) took it for ≥6 mo, of which 3pts receivedpalliative radiation andcontinued CABO therapy beyond PD. Median PFS and median OS with CABO were 4.1 mo (range: 1.2-16.1) and 8.1 mo (range: 0.8-22.5), respectively. At time of analysis, 4 pts were still taking CABO (3 SD, 1 not yet evaluated); 15 pts discontinued CABO: 12 for PD, 1 for Grade 3 hand-foot skin reaction, 1 per pt request, and 1 for transition to hospice; 3 pts died during CABO therapy (bowel obstruction [1], COVID-19 [1], cardiac arrest [1]). Adverse events attributed to CABO were consistent with published reports. Conclusions: In this cohort of heavily pretreated pts who received CABO after LEN+PEM, CABO demonstrated a modest clinical benefit in a minority of pts, underscoring the need to develop effective novel therapies for aRCC.

The second-line treatment of hepatocellular carcinoma with CalliSpheres drug-eluting bead transarterial chemoembolization combined with regorafenib: A safety and efficacy analysis.

This study aimed to investigate the efficacy and safety of CalliSpheres drug-eluting beads transarterial chemoembolization (DEB-TACE) combined with regorafenib in the second-line treatment of unresectable hepatocellular carcinoma. A retrospective analysis was made of 34 patients with unresectable hepatocellular carcinoma (HCC) that had progressed after first-line treatment in Linyi Tumor Hospital from October 2019 to June 2021. These patients were divided into observation group (n = 15) and control group (n = 19) based on their treatment plans, who were respectively treated with regorafenib alone and regorafenib combined with DEB-TACE. The objective response rate (ORR) and the disease control rate (DCR) were evaluated by the modified Response Evaluation Criteria in Solid Tumors (mRECIST), and the progression-free survival (PFS) and the overall survival (OS) were calculated; the factors influencing PFS and OS of patients were analyzed by the Cox proportional hazards model; and the adverse reactions to the treatments were observed and recorded. After 2months of treatment, the ORR and the DCR of the observation group were 73.3% (11/15) and 86.7% (13/15) respectively, both higher than 10.5% (2/19) and 47.4% (9/19) of the control group. Their differences are statistically significant (P < 0.05). There were no statistically significant differences in the incidences of regorafenib-related adverse reactions including hand-foot skin reactions, fatigue, hypertension, diarrhea, and proteinuria between the two groups (P > 0.05). In the observation group, the main adverse reactions to DEB-TACE such as fever, pain, nausea, and vomiting were relieved after symptomatic treatment, and no serious complications such as ectopic embolization of CalliSpheres drug-eluting beads occurred. As of July 31, 2022, the median follow-up time was 12.5months, and the average was (14.00 ± 5.69) months. The median PFS was 9months in the observation group, and 6months in the control group, presenting a statistically significant difference (P < 0.05), and the median OS was 18months in the observation group, and 12months in the control group, also presenting a statistically significant difference (P < 0.05). The results of monofactor prognostic analysis showed that Child grade, AFP level, and treatment method had an influence on the PFS and the OS of liver cancer patients receiving regorafenib second-line treatment (P < 0.05), and the results of multifactor prognostic analysis showed that child grade and treatment method independently influenced the PFS of patients, while treatment method independently influenced the OS of patients (P < 0.05). DEB-TACE combined with regorafenib is safe and feasible in the treatment of unresectable HCC, with good efficacy and mild adverse reactions.

Tyrosine kinase inhibitors in patients with neuroendocrine neoplasms: a systematic literature review.

Several tyrosine kinase receptors inhibitors (TKIs) have demonstrated antiproliferative effects in well-differentiated neuroendocrine tumors (NETs). We aimed to summarize and appraise the current evidence of the efficacy of TKIs in patients with different types of NETs. We performed a systematic review of clinical trials of TKIs in patients with advanced gastroenteropancreatic or lung NETs (PROSPERO registration number: CRD42024507379). Population characteristics, efficacy, and safety results were summarized by type of NET. Twenty-eight studies were eligible, totaling 2284 patients. While sunitinib remains the only Food and Drug Administration-approved TKI in patients with NETs (for patients with pancreatic well-differentiated NETs), recent placebo-controlled randomized trials have demonstrated improved response rates and progression-free survival for patients with progressive and pre-treated well-differentiated pancreatic (cabozantinib or surufatinib) or gastrointestinal (GI) NETs (pazopanib, cabozantinib, or surufatinib). There is limited evidence to support the use of a TKI in patients with lung or grade 3 NETs. The toxicity associated with TKIs follows a class effect, with a significant proportion of patients experiencing fatigue, hypertension, and hand-foot skin reactions. TKIs are effective therapies in patients with pancreatic or GI well-differentiated NETs and should be part of the therapeutical sequencing of these patients.

Safety and Efficacy of Lenvatinib in Very Old Patients with Unresectable Hepatocellular Carcinoma.

Data concerning the use of lenvatinib in very old patients (≥ 80years) are limited, although the incidence of hepatocellular carcinoma (HCC) in this patient population is constantly increasing. This analysis aimed to evaluate the efficacy and safety of lenvatinib in a large cohort of very old patients (≥ 80years) with unresectable HCC. The study was conducted on a cohort of 1325 patients from 46 centers in four Western and Eastern countries (Italy, Germany, Japan, and the Republic of Korea) who were undergoing first-line treatment with lenvatinib between July 2010 and February 2022. Patients were stratified according to age as very old (≥ 80years) and not very old (< 80years). The median overall survival (OS) was 15.7 months for patients < 80years old and 18.4months for patients ≥ 80years old [hazard ratio (HR) = 1.02, 95% confidence interval (CI) 0.84-1.25, p = 0.8281]. Median progression free survival (PFS) was 6.3months for patients < 80years old and 6.5months for patients ≥ 80years old (HR = 1.07, 95% CI 0.91-1.25, p = 0.3954). No differences between the two study groups were found in terms of disease control rate (DCR; 80.8% versus 78.8%; p = 0.44) and response rate (RR; 38.2% versus 37.9%; p = 0.88). Patients < 80years old experienced significantly more hand-foot skin reaction (HFSR) grade ≥ 2 and decreased appetite grade ≥ 2. Conversely, patients ≥ 80years old experienced significantly more fatigue grade ≥ 2. In the very old group, parameters associated with prognosis were AFP, albumin-bilirubin (ALBI) grade, Barcelona Clinic Liver Cancer (BCLC), and Child-Pugh score. BCLC stage was the only independent predictor of overall survival (OS; HR = 1.59, 95% CI 1.11-2.29, p = 0.01115). Our study highlights the same efficacy and safety of lenvatinib between very old and not very old patients.

Efficacy and safety of anlotinib in patients with desmoid fibromatosis: a retrospective analysis.

Desmoid fibromatosis is an aggressive fibroblastic neoplasm with a high propensity for local recurrence. Targeted therapy for Desmoid fibromatosis represents a novel avenue in systemic treatment. Anlotinib, a novel multitargeted angiogenesis inhibitor, represents a novel approach for targeted therapy. Therefore, this study aims to assess the efficacy and safety of anlotinib in patients with Desmoid fibromatosis. We retrospectively gathered the clinical medical records of Desmoid fibromatosis patients who underwent anlotinib treatment between June 2019 and November 2023 at our center. Anlotinib was initiated at a daily dose of 12 mg and adjusted based on drug-related toxicity. Tumor response was evaluated using the Response Evaluation Criteria in Solid Tumors 1.1 criteria. Progression-free survival served as the primary endpoint and was analyzed utilizing the Kaplan-Meier method. In total, sixty-six consecutive patients were enrolled. No patients achieved a complete response; however, fourteen patients (21.21%) exhibited a partial response, while forty-six patients (70%) experienced disease stability. Progressive disease was observed in 6 patients (9.10%), and the progression-free survival rates at 12 and 36months were 89.71% and 82.81%, respectively. The disease control rate was 90.91%, while the objective response rate was 21.21%. Anlotinib proves effective in managing recurrent and symptomatic patients with Desmoid fibromatosis. However, the toxicity profile of anlotinib presents a higher risk of Hand-Foot Skin Reaction and hypertension. Therefore, given that 41.67% of patients were subjected to dose adjustments associated with the initial dose of 12 mg, implementing dosage reductions may help balance efficacy with side effects.

Efficacy and safety of camrelizumab combined with TACE for hepatocellular carcinoma: a systematic review and meta-analysis.

Hepatocellular carcinoma (HCC) represents a highly lethal and recurrent neoplasm, with limited effective treatment regimens available. Camrelizumab, as a novel PD1 inhibitor combined with transcatheter arterial chemoembolization (TACE), has been widely used in the treatment of HCC. However, there remains a contentious debate regarding the clinical value of the TACE and camrelizumab combination. This study seeks to investigate the efficacy and safety of this combination treatment regimen in patients with HCC. The related studies were retrieved from four online databases, including Pubmed, Cochrane Library, EMBASE, and Web of Science, up to June 1, 2023. The selection of studies was based on screening of titles, abstracts, and full-texts. The primary efficacy outcomes included complete response (CR), objective response rate (ORR), and disease control rate (DCR), while safety outcomes evaluated all treatment-related adverse events (AEs). Additionally, secondary outcomes such as overall (OS) and progression-free survival (PFS) were extracted for further survival analysis. The quality of the included trials was assessed using the MINORS tool. Publication bias was evaluated through funnel plot and Egger's test. A total of 17 publications involving 1,377 cases were included. The pooled CR rate, ORR, and DCR of the patients treated with TACE plus camrelizumab had a pooled CR rate of 8% (95% CI: 0.01-0.15, p=0.03), ORR of 47% (95% CI: 0.42-0.52, p<0.00001) and DCR of 82% (95% CI: 0.77-0.88, p<0.00001), respectively. Compared with a control group that did not receive TACE or camrelizumab, the pooled RR of CR rate, ORR, and DCR were 1.61 (95% CI: 1.27-2.04, p<0.0001), 1.56 (95% CI: 1.19-2.05, p=0.001) and 1.55 (95% CI: 1.19-2.03, p=0.001), respectively. Besides, the combination regimen can prolong the OS (HR=2.60, 95% CI: 2.25-3.02, p<0.00001) and PFS (HR=4.90, 95% CI: 1.94-12.38, p=0.0008). However, the incidence of treatment-related AEs was relatively high (77%), with 29% for grade 3 AEs. The most common AEs observed were pain (47%), fever (46%), hepatic function abnormalities (44%), hypoalbuminemia (39%), and hypertension (37%). The combination treatment did not increase the incidence of AEs compared to the control group, except for the hand-foot skin reaction (RR=0.85, 0.74-0.97, p=0.01), hepatic encephalopathy (RR=4.29, 2.51-7.35, p<0.00001) and nausea (RR=1.35, 1.13-1.61, p=0.001). Combination therapy of TACE plus camrelizumab has shown notable clinical benefits, improved survival, and a manageable safety profile in patients with HCC, but it is essential to monitor and manage the specific toxicities, especially for the camrelizumab-related AEs.

Development and evaluation of regorafenib loaded liquid suppository for rectal delivery: In vitro, in vivo analyses

Regorafenib (RG), a multi-targeting kinase inhibitor, has recently been used in the colorectal cancer (CRC) treatment. However, its clinical effectiveness is severely constrained by its poor water solubility, extensive hepatic metabolism, low oral bioavailability, and serious side effects like Hand-foot skin reaction (HFSR), rashes, fatigue, stomatitis, diarrhea, dizziness and hypertension. Therefore, it is necessary to investigate alternative administration routes in order to increase RG efficacy. The aim of this study was to develop RG loaded liquid suppository with enhanced bioavailability and reduced toxicity. RG loaded liquid suppository was optimized using Design Experts® software, with various quantities of drug (RG), polymers [poloxamer 407 (P407), and poloxamer 188 (P188)], surfactant [Tween® 80, (T80)] and distilled water. Physicochemical characterization and in vitro study of RG release behavior from liquid suppository [RG/P188/P407/T80/distilled water: 1.25/15/11/10/62.75; %] were investigated followed by in vitro cell lines study on Caco-2 and HCT 116 cell lines. Additionally, pharmacokinetics, in vivo safety and in vivo localization studies were carried out following rectal administration in Sprague-Dawley rats. Results showed that increased P407 and T80 concentrations significantly lowered the temperature and time required for gelation, while the strength and mucoadhesion of gel was meaningfully enhanced. However, RG concentration increased didn't show significant effect on all these parameters. RG loaded liquid suppository displayed a significantly improved in vitro release, augmented in vivo localization, and enhanced bioavailability, when compared with the RG suspension. In vitro cell lines data demonstrated that unlike normal saline treated cell lines, the RG loaded liquid suppository and RG suspension has significantly reduced the cancer cell burden, which was also observed through their lower IC50 values. Histopathology study confirmed the formulation's safety for rectal administration, whereas, RG suspension instigated severe damage to the rectal tissues. It can be concluded from the results that RG loaded liquid suppository has a great potential to target CRC with enhanced drug localization, improved bioavailability and no toxic effects at the application's site.

Impact of telephone follow-up on hepatocellular carcinoma patients receiving oral chemotherapy from an ambulatory-care setting.

In recent years, most molecular target drugs have been administered orally, as prescribed at ambulatory services in hospitals and at patients' homes. Telephone follow-up is increasingly being used in clinical practice for patients needing additional support post-discharge and for the prevention of hospital readmissions. The purpose of this study was to clarify the clinical benefits of telephone follow-up while administering oral anticancer drugs. This was a single-center, observational, retrospective study. We evaluated hepatocellular carcinoma patients who received sorafenib or lenvatinib between March 2010 and February 2018. The primary endpoint was the incidence of adverse events. From the total of 130 patients, 83 patients received telephone follow-up and 47 did not. The incidence of hand-foot skin reactions significantly reduced in patients with telephone follow-up (odds ratio (OR) 3.69, 95% confidence interval (CI) 1.16-11.8, p = 0.020). The median durations (ranges) of adherence to oral chemotherapy were 259 days (15-1730) for the telephone follow-up group and 121 days (14-1105) for the no-telephone follow-up group (p < 0.001). Moreover, the disease control rate was significantly higher in the telephone follow-up group (OR 2.52, 95% CI 1.15-5.53, p = 0.020). Remote interventions, such as telephone follow-up, are useful means of managing adverse events in patients receiving oral anticancer drugs and can lead to improved treatment results.
