ABSTRACT
ABSTRACT: No US Food and Drug Administration- or European Medicines Agency-approved therapies exist for bleeding due to hereditary hemorrhagic telangiectasia (HHT), the second-most common inherited bleeding disorder worldwide. The current standard of care (SOC) includes iron and red cell supplementation, alongside the necessary hemostatic procedures, none of which target underlying disease pathogenesis. Recent evidence has demonstrated that bleeding pathophysiology is amenable to systemic antiangiogenic therapy with the anti-vascular endothelial growth factor bevacizumab. Despite its high cost, the addition of longitudinal bevacizumab to the current SOC may reduce overall health care resource use and improve patient quality of life. We conducted, to our knowledge, the first cost-effectiveness analysis of IV bevacizumab in patients with HHT with the moderate-to-severe phenotype, comparing bevacizumab added to SOC vs SOC alone. The primary outcome was the incremental net monetary benefit (iNMB) reported over a lifetime time horizon and across accepted willingness-to-pay thresholds, in US dollar per quality-adjusted life year (QALY). Bevacizumab therapy accrued 9.3 QALYs while generating $428 000 in costs, compared with 8.3 QALYs and $699 000 in costs accrued in the SOC strategy. The iNMB of bevacizumab therapy vs the SOC was $433 000. No parameter variation and no scenario analysis, including choice of iron supplementation product, changed the outcome of bevacizumab being a cost-saving strategy. Bevacizumab therapy also saved patients an average of 133 hours spent receiving HHT-specific care per year of life. In probabilistic sensitivity analysis, bevacizumab was favored in 100% of all 10 000 Monte Carlo iterations across base-case and all scenario analyses. Bevacizumab should be considered for more favorable formulary placement in the care of patients with moderate-to-severe HHT.

INTRODUCTION: Glioblastoma (GBM) is the most common central nervous system malignancy in adults. Despite decades of developments in surgical management, radiation treatment, chemotherapy, and tumor treating field therapy, GBM remains an ultimately fatal disease. There is currently no definitive standard of care for patients with recurrent glioblastoma (rGBM) following failure of initial management. OBJECTIVE: In this retrospective cohort study, we set out to examine the relative effects of bevacizumab and Gamma Knife radiosurgery on progression-free survival (PFS) and overall survival (OS) in patients with GBM at first-recurrence. METHODS: We conducted a retrospective review of all patients with rGBM who underwent treatment with bevacizumab and/or Gamma Knife radiosurgery at Roswell Park Comprehensive Cancer Center between 2012 and 2022. Mean PFS and OS were determined for each of our three treatment groups: Bevacizumab Only, Bevacizumab Plus Gamma Knife, and Gamma Knife Only. RESULTS: Patients in the combined treatment group demonstrated longer post-recurrence median PFS (7.7 months) and median OS (11.5 months) compared to glioblastoma patients previously reported in the literature, and showed improvements in total PFS (p=0.015), total OS (p=0.0050), post-recurrence PFS (p=0.018), and post-recurrence OS (p=0.0082) compared to patients who received either bevacizumab or Gamma Knife as monotherapy. CONCLUSION: This study demonstrates that the combined use of bevacizumab with concurrent stereotactic radiosurgery can have improve survival in patients with rGBM.

The evolution in systemic therapies in hepatocellular carcinoma (HCC) signifies a strategy of high-cost, high-gain innovation that originated with sorafenib, despite its limited impact on tumor response. This strategic approach paved the way for the emergence of a second wave of the short-lived competitive advantage, exemplified by the incorporation of atezolizumab plus bevacizumab and tremelimumab plus durvalumab. In the context of safety concerns within the liver cancer domain, the IMBRAVE150 and HIMALAYA trials boldly incorporated bevacizumab and tremelimumab, respectively, demonstrating the continuation of the high-risk, high-reward innovation paradigm. This review delves into the strengths, weaknesses, opportunities, and threats analysis of systemic therapies in the field of HCC.

Importance: The combination of immune checkpoint inhibitors with antiangiogenic agents has revolutionized the treatment landscape of advanced hepatocellular carcinoma (HCC). However, due to rapid publication of new studies that attained their predefined primary end points, a lack of robust cross-trial comparison of first-line therapies, and diverging clinical guidelines, no clear-cut treatment flowchart and sequence of therapies are available. This critical analysis of the recommendations for the management of advanced HCC from the main scientific societies in the US and Europe adopted an integrated approach to provide information on the clinical benefit (overall survival and progression-free survival) and safety profile of these therapies using the European Society for Medical Oncology (ESMO)-Magnitude of Clinical Benefit Scale (MCBS) score and an ad hoc network meta-analysis. Observations: There is a major consensus among guidelines that atezolizumab plus bevacizumab has a primacy as the recommended first-line treatment of choice in advanced HCC. On progression after immunotherapy-containing regimens and for patients with contraindications for immunotherapies, most guidelines maintain the established treatment hierarchy, recommending lenvatinib or sorafenib as the preferred options, followed by either regorafenib, cabozantinib, or ramucirumab. Thus far, the first-line immune-based regimen of tremelimumab plus durvalumab has been integrated only in the American Association for the Study of Liver Diseases guidance document and the latest National Comprehensive Cancer Network guidelines and has particular utility for patients with a high risk of gastrointestinal bleeding. Overall, in the first-line setting, both atezolizumab plus bevacizumab and sintilimab plus IBI305 (a bevacizumab biosimilar) and durvalumab plus tremelimumab received the highest ESMO-MCBS score of 5, indicating a substantial magnitude of clinical benefit. In a network meta-analysis, no significant differences in overall survival were found among the various combination regimens. However, the newly reported combination of camrelizumab plus rivoceranib was associated with a significantly higher risk of treatment-related adverse events compared with atezolizumab plus bevacizumab (relative risk, 1.59; 95% CI, 1.25-2.03; P < .001). Conclusions and Relevance: This narrative review found that atezolizumab plus bevacizumab is regarded as the primary standard of care for advanced HCC in the first-line setting. These findings from integrating the recommendations from scientific societies' guidelines for managing advanced HCC along with new data from cross-trial comparisons may aid clinicians in decision-making and guide them through a rapidly evolving and complex treatment landscape.

INTRODUCTION: Systemic therapy is recommended for patients with Child-Pugh A in hepatocellular carcinoma (HCC). We analyzed the outcomes of a cohort of patients with HCC who received either sorafenib (Sor), lenvatinib (Len) or atezolizumab plus bevacizumab (Atezo + Bev) as first-line systemic therapy for HCC, with the aim of identifying prognostic factors for survival. METHODS: A total of 825 patients with advanced HCC and Child-Pugh A or B received either Sor, Len or Atezo + Bev as first-line systemic therapy. Liver function was assessed according to the Child-Pugh score and the modified albumin-bilirubin (mALBI) grade. RESULTS: Prognosis was analyzed according to liver function such as Child-Pugh classifications, scores, and mALBI grades that worsened with a decline in liver function (p <0.001 for all). A Child-Pugh score of 7 was a factor significantly associated with OS. In patients with a Child-Pugh score of 7, an mALBI grade of 3 was an independent predictor of OS. In Child-Pugh B patients with HCC, receiving Atezo + Bev was identified as a factor associated with PFS. CONCLUSION: Determining the hepatic reserve of patients with unresectable HCC might be useful for identifying patents suitable for systemic treatment for HCC. Atezo + Bev might prolong the PFS of patients with a Child-Pugh score of 7.

Bevacizumab plays an important role in the first and second line treatment for metastatic colorectal cancer (CRC). And induction of hypoxia and the tumors response to it plays an important role in determining the efficacy of antiangiogenic therapy while the connection between them remains unclear. Here, we found that lactate accumulated in the tumor environment of CRC and acted as substrates for histone lactylation, and this process was further induced by cellular enhanced glycolysis in hypoxia. We determined that CRC patients resistant to bevacizumab treatment presented with elevated levels of histone lactylation and inhibition of histone lactylation efficiently suppressed CRC tumorigenesis, progression and survival in hypoxia. Histone lactylation promoted the transcription of RUBCNL/Pacer, facilitating autophagosome maturation through interacting with BECN1 (beclin 1) and mediating the recruitment and function of the class III phosphatidylinositol 3-kinase complex, which had a crucial role in hypoxic cancer cells proliferation and survival. Moreover, combining inhibition of histone lactylation and macroautophagy/autophagy with bevacizumab treatment demonstrated remarkable treatment efficacy in bevacizumab-resistance patients-derived pre-clinical models. These findings delivered a new exploration and important supplement of metabolic reprogramming-epigenetic regulation, and provided a new strategy for improving clinical efficacy of bevacizumab in CRC by inhibition of histone lactylation.Abbreviations: 2-DG: 2-deoxy-D-glucose; BECN1: beclin 1; CQ: chloroquine; CRC: colorectal cancer; DMOG: dimethyloxalylglycine; H3K18la: histone H3 lysine 18 lactylation; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; Nala: sodium lactate; PDO: patient-derived orgnoid; PDX: patient-derived xenograft; RUBCNL/Pacer: rubicon like autophagy enhancer; SQSTM1/p62: sequestosome 1.

Introduction: Cerebral radiation necrosis is rarely encountered in pediatric patients. This case report describes a child with cerebral radiation necrosis who was successfully treated using corticosteroids, bevacizumab, and hyperbaric oxygenation. Case report: A 3-year-old boy developed progressive extremity weakness six months after the completion of radiation therapy for the treatment of a neuroepithelial malignancy. Treatment with corticosteroids and bevacizumab was initiated, but his symptoms did not improve, and he was then referred for hyperbaric oxygen therapy. After completing 60 hyperbaric treatments, he experienced significant improvements in mobility, which remained stable over the next year. Discussion: Cerebral radiation necrosis typically presents in children with symptoms of ataxia or headache. Corticosteroids and bevacizumab are common treatments, but hyperbaric oxygen therapy has also been studied as a therapeutic modality for this condition. When considering the use of hyperbaric oxygenation in pediatric patients, careful attention to treatment planning and patient safety can reduce the risks of adverse events such as middle ear barotrauma and confinement anxiety. Conclusion: In addition to other available pharmacologic therapies, hyperbaric oxygenation should be considered for the treatment of pediatric patients with cerebral radiation necrosis.

OPINION STATEMENT: Multiple treatment options are now approved for unresectable hepatocellular carcinoma (HCC). An immune checkpoint inhibitor (ICI)-containing regimen should be highly considered as the first-line treatment when there is no contraindication, especially in those with hepatitis virus-related HCC, due to proven superior overall survival (OS) compared to sorafenib. Atezolizumab plus bevacizumab and durvalumab plus tremelimumab remain the treatment of choice among all ICI-containing regimens, unless contraindications to either of the medications exist. Although sorafenib is still the only medication currently approved for select patients with Child-Pugh B (CP) HCC in the first-line setting, atezolizumab plus bevacizumab is being studied in this patient population. Moreover, patients with post-liver transplantation recurrence may benefit from tyrosine kinase inhibitors (TKIs), while more studies are still needed to determine the safety of ICIs in this setting. Interestingly, multiple potential biomarkers, including tumor mutational burden (TMB), microsatellite instability (MSI) status, and PD-L1 expression level, have inconsistently predicted response to ICIs in patients with HCC. Limited evidence is available to guide treatment choice in later-line settings after progressing on ICIs, and decisions should be based on the safety profile of the treatment regimen and patient preference. Multiple trials are ongoing to elucidate the optimal treatment sequence. Of note, we believe that TKIs (e.g., cabozantinib, regorafenib, lenvatinib, and sorafenib) could be more beneficial in later-line settings to broaden inhibition of other pathways apart from vascular endothelial growth factor (VEGF). When conventional treatment options are exhausted, tissue biopsy may be helpful to reveal rare targetable mutations, such as RET gene fusions.

Objective: To observe the effect of peritumoral electroacupuncture on the induction of vascular normalization in a mouse breast cancer model. Methods: A subcutaneous graft model of breast cancer was established with 4T1 breast cancer cell line in female BALB/c mice aged 6-8 weeks. The mice were randomly assigned to three groups, a tumor-bearing group (TG), peritumoral electroacupuncture tumor-bearing group (EATG), and bevacizumab tumor-bearing group (BTG), with 18 mice in each group. The TG mice did not receive any intervention, the EATG mice received peritumoral electroacupuncture for 30 minutes, and the BTG mice were intraperitoneally injected with bevacizumab at 10mg/kg. Immunofluorescence was performed to assess the expression of CD31/alpha smooth muscle actin (α-SMA) and hypoxia-inducible factor 1-alpha (HIF-1α) in the tumor tissue at various points of time, including before intervention and 3 days and 5 days after intervention. Then, 3 days after intervention, observation of morphological changes of the microvessels in the tumor tissue was performed through Hematoxylin and Eosin (HE) staining and scanning electron microscope. Results: There was no significant difference in the expression of CD31, α-SMA, and HIF-1α in the tumor tissues of all groups before experimental intervention ( P>0.05). On day 3 of the experimental interventions, the CD31 and HIF-1α expression levels in the tumor tissues of the EATG and BTG mice were significantly reduced ( P<0.01), while α-SMA expression levels were significantly increased ( P<0.01) in both groups. On day 5 of the experimental interventions, the CD31 and HIF-1α expression levels in the tumor tissues of the EATG and BTG mice were still significantly lower than those in the TG mice ( P<0.01), while the α-SMA expression level was significantly higher than that in the TG group ( P<0.05). On day 3 of the experimental interventions, H&E staining showed visible microvessels in the tumor tissues of all 3 groups. In addition, scanning electron microscopic observation showed that the tumor microvessel walls of the TG mice were rough and defective, and that obvious deformities appeared in the lumen. In contrast, the walls of the microvessels of the EATG and BTG mice were generally intact and there was no obvious deformities in the lumen. Conclusion: Peritumoral electroacupuncture may induce microvasculature normalization by decreasing microvascular density and increasing pericyte coverage of the neovasculature, thereby improving hypoxic microenvironment of breast cancer in mice.

It has been reported that patients with macroscopic vascular invasion accompanying hepatocellular carcinoma have a poor prognosis. Modern molecular therapy with multitargeted tyrosine kinase inhibitors and immune checkpoint inhibitors has shown promising results in patients with metastatic hepatocellular carcinoma; however, molecular therapy is limited to patients with Child-Pugh class A disease. This review summarizes the present status of surgical therapies, including conversion hepatectomy, for patients with MVI in the developing era of novel molecular therapy. Phase III studies showed patients with macroscopic vascular invasion had significant survival benefits from sorafenib [hazard ratio (HR)=0.68] and regorafenib (HR=0.67) versus placebo, and nivolumab (HR=0.74) versus sorafenib. Lenvatinib and atezolizumab plus bevacizumab showed marginal effects. It is currently widely assumed that molecular therapy alone will not cure the disease but that additional conversion hepatectomy will be required. A response other than progressive disease is essential but a pathological complete response is not always required. A significant randomized controlled trial has already started in China to assess the necessity for conversion hepatectomy after effective atezolizumab plus bevacizumab treatment, and the results are still awaited. According to Japanese national data, upfront hepatectomy can be recommended for patients with initially resectable disease and macroscopic vascular invasion other than for those with tumors in the main portal vein and the inferior vena cava. In addition, adequate adjuvant therapies with hepatic arterial chemotherapy and transarterial chemoembolization may be beneficial but an effective adjuvant molecular therapy is currently unavailable. In conclusion, novel molecular therapies with higher response rates customized to the oncologic characteristics of each hepatocellular carcinoma with macroscopic vascular invasion are needed to increase the likelihood of conversion surgery and improve long-term outcomes.

INTRODUCTION: Pseudomyxoma peritonei (PMP) is a rare, slow growing tumor, traditionally considered chemoresistant. The only curative approach is cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC). At disease relapse, or in patients with inoperable disease at diagnosis, no standard treatment has been defined, though nonrandomized series showed promising results with fluoropyrimidine-based regimens. PATIENTS AND METHODS: We conducted a prospective study in patients with relapsed or unresectable PMP and confirmed disease progression at baseline. Patients received MMC (7 mg/m2 every 6 weeks, up to a maximum of 4 cycles) plus metronomic capecitabine (625 mg/sqm/day b.i.d.) and bevacizumab (7.5 mg/kg every 3 weeks) until disease progression, unacceptable toxicity, or consent withdrawal. Primary endpoint was progression-free survival (PFS); secondary endpoints were overall survival (OS), overall response rate according to RECIST v1.1 criteria, serum markers response and safety. RESULTS: Fifteen patients were included. At a median follow-up of 26.1 months (IQR, 17.7-49.6), median PFS was 17.9 months (95% CI, 11.0-NE), with 1-year PFS and OS rates of 73% and 87%. Safety profile was manageable, with only 13% G3/G4 treatment-related adverse events. CONCLUSION: Metronomic capecitabine, bevacizumab, and MMC are an active regimen in advanced and progressive PMP and favorably compares with historical series.

RATIONALE: Signet-ring cell carcinoma, which is an infrequent type of colorectal cancer. Abdominal pain is the primary presenting complaint of patients with acute appendicitis. It is difficult to diagnose patients with appendiceal carcinomas accompanying with symptoms of acute appendicitis. PATIENT CONCERNS: A 33-year-old female patient was admitted to our hospital, with chief complaints of "bilateral pelvic space-occupying lesions for 1 month, aggravated abdominal distension, and she accompanied with diarrhea for 3 days." DIAGNOSIS: The patient was with primary signet ring cell carcinoma of the appendix, presented with acute appendicitis, as well as bilateral ovarian metastasis and peritoneal implantation metastasis. INTERVENTIONS: She was then treated with irinotecan, oxaliplatin, calcium folinate, 5-FU combined with bevacizumab, surgical treatment, and postoperative adjuvant treatment with oxaliplatin, capecitabine regimen to consolidate the efficacy. OUTCOMES: The patient is in good conditions, and postoperative adjuvant chemotherapy is in progress as well. CONCLUSION: The outcomes highlighted the importance of strict histopathologic assessment for appendiceal adenocarcinoma, and provided new ideas for the diagnosis and treatment of advanced-stage signet ring cell carcinoma of the appendix.

BACKGROUND/AIM: The choice of chemotherapy agents for RAS-mutant colorectal cancer is limited, and prognosis is poor compared to RAS-wild-type colorectal cancer. The purpose of the present study was to evaluate the effectiveness of methionine restriction combined with chemotherapy in a patient with NRAS-mutant rectal cancer. PATIENTS AND METHODS: A 59-year-old female was diagnosed with lung-metastatic recurrence of NRAS-mutant rectal cancer two and a half years after resection of the primary tumor. She started chemotherapy, which consisted of fluorouracil, irinotecan (FOLFIRI), and bevacizumab, in October 2020. Eight months later, stereotactic body radiation therapy (SBRT) was performed to treat the lung metastases. She stopped chemotherapy at this point and had blood tests and computed tomography (CT) scans regularly. Her CEA level increased to 139.91 ng/ml and her lung metastasis became larger by September 2022. Therefore, she was reintroduced to FOLFIRI and bevacizumab in October 2022, and also started a low-methionine diet and oral recombinant methioninase (o-rMETase) as a supplement. RESULTS: After starting the combination therapy with o-rMETase, a low-methionine diet, FOLFIRI, and bevacizumab, blood CEA levels very rapidly decreased and were almost within the normal limits five months later. CT findings showed the lung metastasis did not grow. CONCLUSION: Methionine restriction comprising o-rMETase and a low-methionine diet combined with first-line chemotherapy was effective in a patient with NRAS-mutant rectal cancer in which metastasis had re-occurred after first-line chemotherapy alone.

PURPOSE: Triplet chemotherapy might be more effective than doublet chemotherapy in metastatic colorectal cancer (mCRC), but it may also be marked by increased toxicity. To investigate whether δ-tocotrienol, a vitamin E analogue, with possible neuroprotective and anti-inflammatory effects, reduces the toxicity of triplet chemotherapy, we conducted a randomized, double-blind, placebo-controlled trial in mCRC patients receiving first-line 5-fluorouracil, oxaliplatin and irinotecan (FOLFOXIRI). MATERIAL AND METHODS: Seventy patients with mCRC were randomly assigned (1:1) to receive FOLFOXIRI plus either δ-tocotrienol or placebo at the Department of Oncology, Vejle Hospital, Denmark. Eligibility criteria were adenocarcinoma in the colon or rectum, age 18-75 years and ECOG performance status 0-1. FOLFOXIRI was given in eight cycles followed by four cycles of 5-fluorouracil. δ-tocotrienol 300 mg or placebo × 3 daily was added during chemotherapy and for a maximum of two years. The primary endpoint was time to hospitalization or death during treatment with chemotherapy. RESULTS: Median time to first hospitalization or death was 3.7 months in the placebo group (95% CI 1.93-not reached (NR)), and was NR in the δ-tocotrienol group (95% CI 1.87-NR) with a hazard ratio of 0.70 (95% CI 0.36-1.36). Grade 3-4 toxicities were uncommon in both groups, except for neutropenia, which occurred in 19 patients (58%) in the placebo group and 17 patients (50%) in the δ-tocotrienol group. There were no grade 3 or 4 peripheral sensory neuropathy. In the placebo group, 24 patients (71%) had oxaliplatin dose reductions compared to 17 patients (47%) in the δ-tocotrienol group (p = 0.047). CONCLUSION: The addition of δ-tocotrienol to FOLFOXIRI did not statistically significant prolong the time to first hospitalization or death compared to FOLFOXIRI plus placebo. Toxicity was manageable and not statistically different. There was a statistically significant difference in dose reductions of oxaliplatin pointing to a possible neuroprotective effect of δ-tocotrienol.

BACKGROUND: Patients with colorectal peritoneal metastases who are not eligible for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) owing to extensive peritoneal disease have a poor prognosis. It was hypothesized that these patients may benefit from the addition of intraperitoneal irinotecan to standard palliative systemic chemotherapy. METHODS: This was a classical 3 + 3 phase I dose-escalation trial in patients with colorectal peritoneal metastases who were not eligible for CRS-HIPEC. Intraperitoneal irinotecan was administered every 2 weeks, concomitantly with systemic FOLFOX (5-fluorouracil, folinic acid, oxaliplatin)-bevacizumab. The primary objective was to determine the maximum tolerated dose and dose-limiting toxicities. Secondary objectives were to elucidate the systemic and intraperitoneal pharmacokinetics, safety profile, and efficacy. RESULTS: Eighteen patients were treated. No dose-limiting toxicities were observed with 50 mg (4 patients) and 75 mg (9 patients) intraperitoneal irinotecan. Two dose-limiting toxicities occurred with 100 mg irinotecan among five patients. The maximum tolerated dose of intraperitoneal irinotecan was established to be 75 mg, and it was well tolerated. Intraperitoneal exposure to SN-38 (active metabolite of irinotecan) was high compared with systemic exposure (median intraperitoneal area under the curve (AUC) to systemic AUC ratio 4.6). Thirteen patients had a partial radiological response and five had stable disease. Four patients showed a complete response during post-treatment diagnostic laparoscopy. Five patients underwent salvage resection or CRS-HIPEC. Median overall survival was 23.9 months. CONCLUSION: Administration of 75 mg intraperitoneal irinotecan concomitantly with systemic FOLFOX-bevacizumab was safe and well tolerated. Intraperitoneal SN-38 exposure was high and prolonged. As oncological outcomes were promising, intraperitoneal administration of irinotecan may be a good alternative to other, more invasive and costly treatment options. A phase II study is currently accruing.
Patients with extensive colorectal peritoneal metastases who are not eligible for surgery and heated intraperitoneal chemotherapy have poor survival. The authors tried to improve the survival of these patients by adding intraperitoneal (inside the abdominal cavity) chemotherapy to standard palliative chemotherapy which is administered into the bloodstream. In this trial, irinotecan (a type of chemotherapy) was administered into the abdomen of patients with extensive colorectal peritoneal metastases. The authors investigated which dose could be administered safely in combination with standard palliative chemotherapy. They also looked into toxicity, safety, benefit, and movement of the drug in the body. Eighteen patients were treated in this study. The maximum tolerated dose of intraperitoneal irinotecan was 75 mg. It was well tolerated and could be administered safely. The intra-abdominal amount of irinotecan was high, whereas the amount of irinotecan in the blood remained low. The benefits of intra-abdominal irinotecan were promising. Because of this, a new study has been started to further investigate this new combination chemotherapy for colorectal cancer.

INTRODUCTION: Patients with non-small-cell lung cancer (NSCLC) who have never smoked or have tumors with mutations in EGFR generally derive minimal benefit from single-agent PD-1/PD-L1 checkpoint inhibitors. Prior data indicate that adding PD-L1 inhibition to anti-VEGF and cytotoxic chemotherapy may be a promising approach to overcoming immunotherapy resistance in these patients, however prospective validation is needed. This trial in progress (NCT03786692) is evaluating patients with stage IV NSCLC who have never smoked or who have tumors with sensitizing EGFR alterations to determine if a 4-drug combination of atezolizumab, carboplatin, pemetrexed, and bevacizumab can improve outcomes compared to carboplatin, pemetrexed and bevacizumab without atezolizumab. METHODS: This is a randomized, phase II, multicenter study evaluating carboplatin, pemetrexed, bevacizumab with and without atezolizumab in 117 patients with stage IV nonsquamous NSCLC. Randomization is 2 to 1 favoring the atezolizumab containing arm. Eligible patients include: 1) those with tumors with sensitizing EGFR alterations in exons 19 or 21 or 2) patients who have never smoked and have wild-type tumors (ie, no EGFR, ALK or ROS1 alterations). Patients are defined as having never smoked if they have smoked less than 100 cigarettes in a lifetime. Patients with EGFR-mutated tumors must have disease progression or intolerance to prior tyrosine kinase inhibitor (TKI) therapy. The primary endpoint is progression-free survival (PFS). Secondary endpoints include overall survival (OS), response rate, duration of response, and time to response. CONCLUSION: This phase II trial is accruing patients at U.S. sites through the National Comprehensive Cancer Network (NCCN). The trial opened in August 2019 and accrual is expected to be completed in the Fall of 2024.

INTRODUCTION: The aim of this retrospective proof-of-concept study was to compare different second-line treatments for patients with hepatocellular carcinoma and progressive disease (PD) after first-line lenvatinib or atezolizumab plus bevacizumab. MATERIALS AND METHODS: A total of 1381 patients had PD at first-line therapy. 917 patients received lenvatinib as first-line treatment, and 464 patients atezolizumab plus bevacizumab as first-line. RESULTS: 49.6% of PD patients received a second-line therapy without any statistical difference in overall survival (OS) between lenvatinib (20.6months) and atezolizumab plus bevacizumab first-line (15.7months; p = 0.12; hazard ratio [HR]= 0.80). After lenvatinib first-line, there wasn't any statistical difference between second-line therapy subgroups (p = 0.27; sorafenib HR: 1; immunotherapy HR: 0.69; other therapies HR: 0.85). Patients who underwent trans-arterial chemo-embolization (TACE) had a significative longer OS than patients who received sorafenib (24.7 versus 15.8months, p < 0.01; HR=0.64). After atezolizumab plus bevacizumab first-line, there was a statistical difference between second-line therapy subgroups (p < 0.01; sorafenib HR: 1; lenvatinib HR: 0.50; cabozantinib HR: 1.29; other therapies HR: 0.54). Patients who received lenvatinib (17.0months) and those who underwent TACE (15.9months) had a significative longer OS than patients treated with sorafenib (14.2months; respectively, p = 0.01; HR=0.45, and p < 0.05; HR=0.46). CONCLUSION: Approximately half of patients receiving first-line lenvatinib or atezolizumab plus bevacizumab access second-line treatment. Our data suggest that in patients progressed to atezolizumab plus bevacizumab, the systemic therapy able to achieve the longest survival is lenvatinib, while in patients progressed to lenvatinib, the systemic therapy able to achieve the longest survival is immunotherapy.

Importance: The long-term outcomes associated with adding bevacizumab, a vascular endothelial growth factor inhibitor, to standard chemoradiation have continued to be favorable for a group of patients with locoregionally advanced nasopharyngeal carcinoma (NPC). Objective: To assess long-term toxic effects and clinical outcomes associated with chemotherapy, radiation therapy (RT), and bevacizumab for NPC. Design, Setting, and Participants: This single-arm phase II nonrandomized controlled trial was conducted by the National Cancer Trials Network group and NRG Oncology (formerly Radiation Therapy Oncology Group), with accrual from December 13, 2006, to February 5, 2009, and data analysis from June 26 to July 1, 2019. The study was conducted at 19 cancer centers with a median (IQR) follow-up of 9.0 (7.7-9.3) years. Included patients were adults (aged ≥18 years) with NPC that was World Health Organization (WHO) histologic grade I to IIb or III, American Joint Committee on Cancer stage IIB or greater, and with or without lymph node involvement. Interventions: Patients received 3 cycles of bevacizumab (15 mg/kg) concurrently with standard cisplatin (100 mg/m2) and RT (69.96 Gy) followed by 3 cycles of adjuvant bevacizumab (15 mg/kg) given concurrently with cisplatin (80 mg/m2) and fluorouracil (1000 mg/m2/d). Main Outcomes and Measures: The primary end point was grade 4 hemorrhage or grade 5 adverse events in the first year. Secondary end points were locoregional progression-free (LRPF) interval, distant metastasis-free (DMF) interval, progression-free survival (PFS), overall survival (OS), and other adverse events. Long-term toxic effects and clinical outcomes were reported due to the limited follow-up in the initial report for this trial and the importance of long-term outcomes when combining bevacizumab with chemoradiation. Results: Among 46 patients with NPC who were enrolled, 44 patients were analyzed (29 males [65.9%]; 23 Asian [52.3%], 2 Black [4.5%], and 16 White [36.4%]; 38 not Hispanic [86.4%]; median [IQR] age, 48.5 [39.0-56.0] years). There were 33 patients with a Zubrod performance status of 0, indicating that they were fully functional and asymptomatic (75.0%); 32 patients with a WHO histologic grade of IIb or III (72.7%); and 39 patients with stage III or IVB disease (88.6%). Among analyzed patients, 42 individuals received radiation therapy of 69.96 Gy or greater (95.5%; dose range, 65.72-70.00 Gy); 30 patients received 3 cycles of cisplatin (68.2%) with RT, and 31 patients received 3 cycles of bevacizumab with RT (70.5%); this was followed by 3 cycles of adjuvant cisplatin in 21 patients (47.7%), fluorouracil in 24 patients (54.5%), and bevacizumab in 23 patients (52.3%). No grade 4 hemorrhage or grade 5 AEs were reported in the first year or thereafter. Late grade 3 AEs occurred in 16 patients (36.4%), including 7 patients with dysphagia (15.9%), 6 patients with hearing impairment (13.6%), and 2 patients with dry mouth (4.5%). The 1- and 5-year rates of feeding tube use were 5 of 41 patients (12.2%) and 0 of 27 patients, respectively. There were 19 patients (43.2%) who progressed or died without disease progression (6 patients with locoregional progression [13.6%], 8 patients with distant progression [18.2%], and 5 patients who died without progression [11.4%]). The 5- and 7-year rates were 79.5% (95% CI, 67.6%-91.5%) and 69.7% (95% CI, 55.9%-83.5%) for OS, 61.2% (95% CI, 46.8%-75.6%) and 56.3% (95% CI, 41.5%-71.1%) for PFS, 74.9% (95% CI, 61.4%-86.6%) and 72.3% (95% CI, 58.4%-84.7%) for LRPF interval, and 79.5% (95% CI,66.4%-90.0%) for both times for DMF interval. Among 13 patients who died, death was due to disease in 8 patients (61.5%). Conclusions and Relevance: In this nonrandomized controlled trial, no grade 4 hemorrhage or grade 5 AEs were reported in the first year or thereafter among patients with NPC receiving bevacizumab combined with chemoradiation. The rate of distant metastasis was low although 89% of patients had stage III to IVB disease, suggesting that further investigation may be warranted.

Peritoneal effusion is a common event in ovarian cancer (OC) patients. LncRNA H19 and vascular endothelial growth factor (VEGF) are implicated in cancer progression. The study evaluated the curative effect and safety of bevacizumab combined with hyperthermic intraperitoneal chemotherapy (HIPEC) in OC patients with peritoneal effusion and the effect on serum lncRNA H19/VEGF levels. Totally 248 OC patients with peritoneal effusion were treated with intraperitoneal bevacizumab + HIPEC (observation group) or abdominal paracentesis without HIPEC (control group). The clinical efficacy, quality of life, and adverse reactions were evaluated after two treatment cycles. The serum lncRNA H19 and VEGF levels pre-/post-treatment were determined by RT-qPCR and ELISA. The observation group exhibited better clinical efficacy than the control group, evidenced by a higher partial response rate, response rate, and disease control rate. The observation group exhibited reduced physical/cognitive/role/social/emotional function scores and total adverse reactions. LncRNA H19/VEGF levels showed no significant difference between the two groups before treatment but were significantly downregulated in the observation group after treatment. Summarily, intraperitoneal bevacizumab + HIPEC has significant efficacy in treating peritoneal effusion, improves the quality of life, and reduces serum lncRNA H19 and VEGF levels in OC patients, with fewer adverse reactions and higher safety.Impact statementWhat is already known on this subject? The utilization of hyperthermic intraperitoneal chemotherapy (HIPEC) as an emerging treatment option for abdominal malignancies has garnered the attention of numerous researchers over the years, which has significant clinical effects on peritoneal effusion in ovarian cancer and can control patients' conditions and improve their signs and symptoms to a certain extent.What do the results of this study add? In this paper, we investigated the efficacy and safety of intraperitoneal bevacizumab combined with hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal effusion in ovarian cancer. Meanwhile, we compared serum lncRNA H19 and VEGF levels before and after treatment.What are the implications of these findings for clinical practice and/or further research? Our findings may provide a clinically worthy method for the treatment of peritoneal effusion in ovarian cancer. The treatment method reduces serum lncRNA H19 and VEGF levels in patients, which provides a theoretical basis for further research.

BACKGROUND: Oral multikinase inhibitors and immune checkpoint inhibitors (ICIs) are effective for treating advanced hepatocellular carcinoma (aHCC) but may increase cost. This study compared the cost-effectiveness of oral multikinase inhibitors and ICIs in the first-line treatment of patients with aHCC. METHODS: A three-state Markov model was established to study the cost-effectiveness of drug treatment from the perspective of Chinese payers. The key outcomes in this study were total cost, quality-adjusted life years (QALYs), and the incremental cost-effectiveness ratio (ICER). RESULTS: The total costs and QALYs of sorafenib, sunitinib, donafenib, lenvatinib, sorafenib plus erlotinib, linifanib, brivanib, sintilimab plus IBI305, and atezolizumab plus bevacizumab were $9070 and 0.25, $9362 and 0.78, $33,814 and 0.45, $49,120 and 0.83, $63,064 and 0.81, $74,814 and 0.82, $81,995 and 0.82, $74083 and 0.85, and $104,188 and 0.84, respectively. The drug regimen with the lowest ICER was sunitinib ($551 per QALY), followed by lenvatinib ($68,869 per QALY). For oral multikinase inhibitors, the ICER of lenvatinib, sorafenib plus erlotinib, linifanib and brivanib compared with sunitinib was $779576, $1534,347, $1768,971, and $1963,064, respectively. For ICIs, sintilimab plus IBI305 is more cost effective than atezolizumab plus bevacizumab. The model was most sensitive to the price of sorafenib, the utility of PD, and the price of second-line drugs. CONCLUSION: For oral multikinase inhibitors, the order of possible treatment options is sunitinib > lenvatinib > sorafenib plus erlotinib > linifanib > brivanib > donafenib. For ICIs, the order of possible treatment options is sintilimab plus IBI305 > atezolizumab plus bevacizumab.
