Predicting Benefit From FOLFOXIRI Plus Bevacizumab in Patients With Metastatic Colorectal Cancer.

PURPOSE: Patient outcomes may differ from randomized trial averages. We aimed to predict benefit from FOLFOXIRI versus infusional fluorouracil, leucovorin, and oxaliplatin/fluorouracil, leucovorin, and irinotecan (FOLFOX/FOLFIRI), both plus bevacizumab, in patients with metastatic colorectal cancer (mCRC). METHODS: A Cox model with prespecified clinical, molecular, and laboratory variables was developed in 639 patients from the TRIBE2 trial for predicting 2-year mortality. Data from the CHARTA (n = 232), TRIBE1 (n = 504), and CAIRO5 (liver-only mCRC, n = 287) trials were used for external validation and heterogeneity of treatment effects (HTE) analysis. This involves categorizing patients into risk groups and assessing treatment effects across these groups. Performance was assessed by the C-index and calibration plots. The C-for-benefit was calculated to assess evidence for HTE. The c-for-benefit is specifically designed for HTE analysis. Like the commonly known c-statistic, it summarizes the discrimination of a model. Values over 0.5 indicate evidence for HTE. RESULTS: In TRIBE2, the overoptimism-corrected C-index was 0.66 (95% CI, 0.63 to 0.69). At external validation, the C-index was 0.69 (95% CI, 0.64 to 0.75), 0.68 (95% CI, 0.64 to 0.72), and 0.65 (95% CI, 0.65 to 0.66), in CHARTA, TRIBE1, and CAIRO5, respectively. Calibration plots indicated slight underestimation of mortality. The c-for-benefit indicated evidence for HTE in CHARTA (0.56, 95% CI, 0.48 to 0.65), but not in TRIBE1 (0.49, 95% CI, 0.44 to 0.55) and CAIRO5 (0.40, 95% CI, 0.32 to 0.48). CONCLUSION: Although 2-year mortality could be reasonably estimated, the HTE analysis showed that clinically available variables did not reliably identify which patients with mCRC benefit from FOLFOXIRI versus FOLFOX/FOLFIRI, both plus bevacizumab, across the three studies.

Comparison of intravitreal bevacizumab monotherapy and combined laser photocoagulation and intravitreal bevacizumab therapy in the same session in the treatment of aggressive retinopathy of prematurity.

PURPOSE: To compare the results of intravitreal bevacizumab (IVB) monotherapy and combined intravitreal bevacizumab and laser photocoagulation (LPC) therapies applied in the same session to patients with aggressive retinopathy of prematurity (A-ROP) in our clinic. METHODS: The study included 67 eyes of 37 patients diagnosed with A-ROP and treated. Forty-nine eyes treated with anti-vascular endothelial growth factor agent injection monotherapy for A-ROP treatment were included in the first group. The second group consisted of 18 eyes that received injection therapy and LPC treatment. The clinical findings of the two groups were investigated, and their treatment results were compared. RESULTS: Recurrence was observed in 19 of the 49 (38%) eyes in the first group, but there was no recurrence in any of the cases in the second group. While only IVB was applied to eight cases with recurrence, the combination of LPC and IVB treatment was applied to 11 cases. A second recurrence was detected in two of the eight cases that had received IVB monotherapy as a treatment for recurrence and in three of the 11 cases that had received LPC and IVB. The treatment outcomes of the two groups did not statistically significantly differ (P = 0.181). CONCLUSION: We consider that the combined simultaneous LPC and IVB treatment we applied in A-ROP cases is an effective approach, particularly for cases where there are concerns about the patient's ability to attend follow-up appointments.

Factors affecting prognosis and need for anti-vascular endothelial growth factor injections in wet age-related macular degeneration.

PURPOSE: To understand factors affecting visual prognosis and the number of intravitreal antivascular endothelial growth factor (anti-VEGF) injections needed to stabilize wet age-related macular degeneration (AMD). METHODS: In this retrospective cohort, 119 treatment-naïve wet AMD patients were followed for two years. In patients with bilateral disease, the eye with worse best-corrected visual acuity (BCVA) or that received more intravitreal injections was recruited as the study eye. In all visits, BCVA was recorded, ophthalmological examination was performed including macular optical coherence tomography imaging. Twenty health status/lifestyle questions were asked to the patients via phone as potential risk factors. All patients received 3 loading doses of intravitreal bevacizumab injections and received repeat injections of aflibercept or ranibizumab when the eye had a new, active neovascular lesion. RESULTS: Patients who took regular micronutrition had similar visual outcome and injection numbers compared to the ones who did not. Patients with bilateral disease needed less intravitreal injections compared to unilateral AMD patients (p = 0.016) and women on hormone replacement therapy (HRT) required less injections compared to the women who were not (p = 0.024). Female patients had a mean gain of 2.7 letters while male patients lost 3.8 letters (p = 0.038). Wet AMD started at an earlier age in smokers (p = 0.002). Patients with a better education level presented earlier with better BCVA (p = 0.037). CONCLUSION: HRT and anti-VEGF injections to the fellow eye improved the prognosis of wet AMD, while male patients had slightly worse prognosis. Estrogen's protective effects and potential contribution in wet AMD needs further attention. Retrospectively registered: 2020/0622.

[Importance of Measuring the Urine Protein/Creatinine Ratio in Patients with Advanced Hepatocellular Carcinoma Receiving Atezolizumab plus Bevacizumab Treatment].

INTRODUCTION: When we administer atezolizumab plus bevacizumab treatment to patients with advanced hepatocellular carcinoma, we often encounter inconsistent results between the qualitative dipstick urinalysis and the urine protein/creatinine ratio(UPCR)measurements. In this study, we investigated the relationship between qualitative dipstick urinalysis and UPCR in these patients, and assessed whether incorporating UPCR into the testing protocol could prevent unnecessary interruptions during bevacizumab treatment. SUBJECTS AND METHODS: This study analyzed 298 urine samples collected from 61 patients of advanced hepatocellular carcinoma, who were treated with atezolizumab plus bevacizumab at our institution between October 1, 2020, and August 31, 2021. We used UPCR as an alternative test to the 24-hour urine protein and set the discontinuation criteria for bevacizumab at a UPCR of 2.0 or higher. RESULTS: Among the 41 samples that tested positive for 2+ on the dipstick test, only one(2.4%)had a UPCR exceeding 2.0. Additionally, among the 44 samples that showed a 3+ result, 24 samples(54.5%)had a UPCR higher than 2.0. If our decision to discontinue bevacizumab had been based on a dipstick urinalysis result of 2+, we could have continued administering bevacizumab in 97.6%(40/41)of the cases. Even if the decision had been based on a dipstick urinalysis result of 3+, we could have continued administering bevacizumab in almost half of the cases(45.5%, 20/44). CONCLUSIONS: Our findings suggest that the addition of UPCR to the qualitative dipstick urinalysis during atezolizumab plus bevacizumab treatment for patients with advanced hepatocellular carcinoma could help prevent unnecessary interruptions of bevacizumab and offer more clinical benefits in real-world practice, compared to using qualitative dipstick urinalysis alone.

Unusual clinical features and histopathological findings in a case of Pseudo-endophthalmitis in neovascular glaucoma.

Objective: This case report aimed to describe the unusual clinical presentation and histopathological features of post-injection endophthalmitis. Methods: A 56-year-old male phakic patient with diabetic retinopathy received an intravitreal injection (Bevacizumab as per the patient) for neovascular glaucoma elsewhere and presented to our center one day after the dose with hypopyon. The eye was relatively white without pain or lid oedema. The patient was treated as a case of post-injection endophthalmitis with two doses of intravitreal antibiotics 48 hours apart. During the follow-up, he developed a Covid infection. After one week, when the media cleared, white exudates were seen in the vitreous cavity with a relatively healthy retina. He was taken up for pars plana vitrectomy and vitreous biopsy for histopathological study. Results: The microscopic examination of vitreous aspirate revealed crystalline deposits without any microorganisms. Two control slides, one with a mixture of intravitreal antibiotics, which were previously injected, and the other with fresh Triamcinolone were also examined. Although the findings of the drug mixture did not match the vitreous aspirate, they matched with triamcinolone, which established it as a case of pseudo endophthalmitis due to triamcinolone injected elsewhere. Discussion: Initially, it seemed like a straightforward case of post-injection endophthalmitis, but a further examination of the vitreous aspirate showed that it was pseudoendophthalmitis due to an intravitreal triamcinolone injection. Despite the patient being phakic, neovascularization or elevated intraocular pressure may have led to the disruption of the blood-ocular barrier and the migration of Triamcinolone into the anterior chamber. Conclusion: The case's uniqueness lies in being the first reported case of pseudo endophthalmitis in a phakic patient with an intact lens iris diaphragm. The case also highlighted the judicious use of available resources and out-of-the-box thinking to reach a diagnosis that may not always be obvious.

[Advances in the use of bevacizumab for the treatment of respiratory papilloma].

Respiratory papilloma is a relatively common benign tumor of the respiratory tract, and a few patients may develop malignant changes. The disease has an insidious onset and lacks specific clinical manifestations, and its manifestations are closely related to the growth mode, location and size of the tumor. It can involve multiple parts, such as the larynx, trachea, bronchus, and lung parenchyma, which cause coughing, hoarseness, dysphonia, and, in severe cases, may lead to obstruction of the respiratory tract. At present, the treatment of respiratory papilloma lacks standardization, and there is no effective method to cure the disease. Surgery remains the main treatment for alleviating patients' symptoms and preventing airway obstruction. However, due to the high recurrence rate of respiratory papilloma, multiple surgeries are often needed, which reduces the quality of life of patients and increases their disease burden and economic burden. Bevacizumab, a vascular endothelial growth factor-binding antibody inhibitor, is a promising adjuvant treatment modality that shows good potential for reducing symptoms and the frequency of surgery. This article aimed to review the efficacy and safety of bevacizumab for the treatment of respiratory papilloma and discuss the differences and efficacy of the systemic application and intralesional injection of bevacizumab for the treatment of respiratory papilloma.

A Case of Immune Aplastic Anemia during Combined Treatment with Atezolizumab and Chemotherapy for Non-Small Cell Lung Cancer.

Immune check point inhibitors (ICIs) have durable antitumor effects. However, autoimmune toxicities, termed immune-related adverse events, occur in some patients. We report a case of severe immune aplastic anemia (AA) in a patient with non-small cell lung cancer who was receiving atezolizumab with bevacizumab/carboplatin/paclitaxel. Although the cancer has not recurred, his bone marrow is depleted and he did not respond to immunosuppressive therapy. He has survived for 1.5 years with blood transfusions and infection control. Immune AA associated with ICIs is rare, and a treatment has not yet been established. This case report provides information on the management and treatment response of patients with AA caused by ICIs. Further studies should investigate the mechanism and pathogenesis of immune AA caused by ICIs.

Analysis of Factors Predicting the Real-World Efficacy of Atezolizumab and Bevacizumab in Patients with Advanced Hepatocellular Carcinoma.

Background/Aims: Atezolizumab and bevacizumab have shown promising results for the treatment of advanced hepatocellular carcinoma (HCC) in clinical trials. In this study, the real-world efficacy and safety of atezolizumab and bevacizumab in treating advanced HCC were evaluated. Methods: In this retrospective study of patients at a Korean tertiary cancer center, 111 patients with Barcelona Clinic Liver Cancer stage B or C HCC received atezolizumab and bevacizumab as first-line therapy from May 2022 to June 2023. We assessed the progression-free survival (PFS), overall response rate (ORR), disease control rate (DCR), and adverse events. Results: Patients with Barcelona Clinic Liver Cancer stage C HCC and Child-Pugh class A liver function were included in the study. The median PFS was 6.5 months, with an ORR of 27% and a DCR of 63%. Several factors, including the albumin-bilirubin grade, age, C-reactive protein and α-fetoprotein in immunotherapy score, macrovascular invasion, lung metastases, and combined radiotherapy, were found to significantly influence PFS (p<0.05). Patients with peritoneal seeding showed an higher ORR. The safety profile was consistent with that observed in clinical trials. Conclusions: Atezolizumab and bevacizumab demonstrated real-world efficacy in the treatment of advanced HCC, with ORRs and DCRs aligning with those observed in clinical trials. Variations in PFS and ORR based on specific risk factors highlight the potential of atezolizumab and bevacizumab in precision medicine for advanced HCC.

Evaluating the causes of retinopathy of prematurity relapse following intravitreal bevacizumab injection.

BACKGROUND: Retinopathy of prematurity (ROP) is a proliferative disorder of the developing retina. Intravitreal bevacizumab injection (IVB) is an emerging treatment for severe forms of ROP, which does not restrict the visual field in comparison to laser therapy. The present study aimed to determine and evaluate the risk factors for ROP recurrence following IVB injection. MATERIALS AND METHODS: In this retrospective study, 98 eyes of 49 infants with ROP who had received IVB injections as the primary treatment for type 1 ROP are included. RESULTS: Fifty-four eyes (55.1%) had aggressive retinopathy of prematurity (A-ROP), and forty-four (44.9%) had Stage III Plus ROP in Zone II. ROP recurred in 13 eyes (13.26%) of 8 infants. The mean period between IVB and the ROP recurrence was 8.08 (95% CI:5.32-10.83) weeks. The infants who had ROP recurrence had lower birth weight (P value = 0.002), lower postmenstrual age at IVB injection (P value = 0.001), lower IVB injection gap period from birth (P value = 0.044), higher oxygen therapy requirement rate after IVB injection (P value < 0.001, OR:19.0) and higher oxygen therapy duration (P value = 0.006). The ROP severity, gestational age at birth, and diet were not statistically different between the recurrence and complete regression groups. Out of 13 eyes treated with laser photocoagulation because of ROP relapse, macula dragging occurred in one eye, and all the cases met the complete regression. CONCLUSION: Low birth weight and oxygen therapy are the most important risk factors for ROP relapse, which requires meticulous oxygen treatment guidelines for premature infants.

[A Case of Descending Colon Cancer with Local Recurrence Eight Years and Seven Months after Curative Resection and Favorable Response to Pharmacotherapy-A Case Report].

A 73-year-old woman underwent a descending colectomy for descending colon cancer. The tumor was graded as pStage Ⅲb(pT3[SS], pN1b, pM0, Cur A), according to the 9th edition of the Japanese Classification of Colorectal, Appendiceal, and Anal Carcinoma. Postoperative treatment of adjuvant chemotherapy comprised oral tegafur/uracil and Leucovorin for 6 months with no evident recurrence. However, contrast-enhanced CT and FDG-PET/CT examination 8 years and 7 months after surgery revealed a 30 mm irregular recurrent tumor in the left iliac fossa. Since the tumor was adjacent to the left psoas muscle, it was considered that RM0(no tumor identified at the radial margin)could not be achieved in that region. Owing to the patient's good general condition, systemic chemotherapy with CAPOX+bevacizumab was administered. Although adverse events prompted discontinuation of the treatment during the first course, the recurrent tumor had significantly regressed. Systemic chemotherapy with mFOLFOX6+bevacizumab as selected subsequent treatment achieved a significant tumor shrinkage to date. Although a recurrence more than 5 years after curative resection of colorectal cancer is extremely rare, the possibility of late recurrence must be considered in patients with well-differentiated tumors who received adjuvant chemotherapy and had negative vascular invasion.

PD-L1 inhibitor versus PD-1 inhibitor plus bevacizumab with transvascular intervention in unresectable hepatocellular carcinoma.

Both atezolizumab (a PD-L1 inhibitor) plus bevacizumab (A+B) and sintilimab (a PD-1 inhibitor) plus bevacizumab (S+B) are recommended as the first-line regimen for advanced hepatocellular carcinoma (HCC) in China. Different efficacy between the two regimens combined with transvascular intervention for unresectable HCC (uHCC) remain unknown. We retrospectively analyzed uHCC patients treated in three centers by simultaneous combination of A+B or S+B with transarterial chemoembolization (TACE) and FOLFOX-based hepatic arterial infusion chemotherapy (HAIC). Objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and treatment-related adverse events (TRAEs) were compared. Totally 188 patients were included, with 92 and 96 administered A+B+TACE-HAIC (ABTH) and S+B+TACE-HAIC (SBTH), respectively. ORRs (62.0 vs. 70.8%, respectively; P = 0.257) and disease control rates (88.0 vs. 93.8%, P = 0.267) were similar between groups by the mRECIST criteria. ABTH showed no survival advantage over SBTH, with median PFS times of 11.7 months and 13.0 months, respectively (HR = 0.81, 95% CI, 0.52-1.26, P = 0.35) and similar OS times (HR = 1.19, 95% CI, 0.32-4.39, P = 0.8). No significant differences were observed in grade 3-4 TRAEs between groups. Either PD-L1 or PD-1 inhibitor plus bevacizumab combined with TACE-HAIC have similarly excellent therapeutic efficacy with manageable adverse events, representing promising treatment options for uHCC.

Feasibility of atezolizumab and bevacizumab combination regimens in patients with hepatocellular carcinoma and lung cancer taking direct oral anticoagulants.

AIM: Atezolizumab and bevacizumab (Atezo/Bev) combination immunotherapy regimens and direct oral anticoagulants (DOACs) are both associated with bleeding. Therefore, combining Atezo/Bev regimens with DOACs may exacerbate the bleeding risk. This study investigated the feasibility of the Atezo/Bev regimen in patients taking DOACs. METHODS: This retrospective study included 141 patients with unresectable hepatocellular carcinoma (HCC) or advanced lung cancer (LC) treated with Atezo/Bev regimens. Patients who used antithrombotic agents other than DOACs were excluded. Bleeding events during the Atezo/Bev regimen were analyzed. RESULTS: The incidence rates of bleeding of any grade in the DOAC (n = 11) and no antithrombotic agent (NAA) (n = 130) groups were 9.1% and 10.8%, respectively, with no significant differences. Moreover, no significant difference was found in the frequency of bleeding of grade ≥3 between the DOAC and NAA groups. No patients in the DOAC group discontinued the Atezo/Bev regimen because of severe bleeding. Although serum albumin levels, with a hazard ratio (HR) of 0.298 (95% confidence interval [CI]: 0.105-0.847), independently contributed to bleeding events (p = 0.023), DOAC administration did not (HR: 1.357; 95% CI: 0.157-10.54; p = 0.770). Among only patients with HCC (n = 59), none of the five patients taking DOACs experienced bleeding events. A high albumin-bilirubin score (HR: 9.083, 95% CI: 1.118-73.76) was associated with bleeding events (p = 0.039). CONCLUSIONS: DOACs did not have a considerable effect on bleeding events in the Atezo/Bev regimens for HCC or LC. Under careful surveillance for bleeding, Atezo/Bev regimens may be feasible in patients receiving DOACs.

Treatment Regimens of Neovascular Form of Age-Related Macular Degeneration. A Review.

This article presents an overview of treatment regimens of drugs containing antivascular endothelial growth factor for the treatment of neovascular form of age-related macular degeneration. Currently, drugs containing antivascular endothelial growth factor are the only effective treatment for this chronic and progressive disease. The treatment regimens for this disease in the last two decades have seen a shift from a simple endeavor to stabilize the disease to achieving maximum improvement of visual acuity and its maintenance, with improvement of the patient's quality of life and a minimal treatment burden on patients and their families. Other goals of the alternative dosing regimens that have replaced the original fixed regimens were greater individualization of the dosing regimen, better patient cooperation, saving financial costs and reducing the burden on application centers. Age-related macular degeneration, whether dry form or wet form, represents a serious health and socioeconomic problem, as the disease is one of the most common causes of severe and irreversible central visual acuity disorders up to the degree of practical blindness of one or both eyes in people over 50 years of age in developed industrialized countries. The most important issue is to ensure early diagnosis of this disease, followed by prompt and continuous treatment with an individualized proactive treatment regimen, with the aim of stabilizing and improving anatomical and functional results.

A retrospective study of first-line therapy and subsequent pyrotinib treatment in advanced lung adenocarcinoma with HER2 mutations.

OBJECTIVES: HER2 is an infrequently mutated driver gene in non-small cell lung cancer (NSCLC). At present, there has been no comprehensive large-scale clinical study to establish the optimal first-line treatment strategy for advanced lung adenocarcinoma (LUAD) with HER2-Mutant. Besides that, the effectiveness and safety of pyrotinib, a pan-HER inhibitor, in the context of NSCLC are still undergoing investigation. MATERIALS AND METHODS: In this study, we conducted a retrospective data collection of HER2-Mutated advanced LUAD who received first-line treatment and pyrotinib between May 2014 and June 2023. Patients treated with chemotherapy, chemotherapy + immune checkpoint inhibitors (ICIs), chemotherapy + bevacizumab and pyrotinib in first-line treatment. Furthermore, we collected data on the efficacy and safety of pyrotinib in these patients after disease progression. The main endpoint of the study was progression-free survival (PFS). RESULTS: In the final analysis, 89 patients were included in the first-line cohort and 30 patients were included in the pyrotinib cohort. In the first-line treatment cohort, chemotherapy + ICIs, chemotherapy + bevacizumab, and pyrotinib exhibited notable survival benefits compared to chemotherapy (median PFS: 9.87 vs. 7.77 vs. 7.10 vs. 5.40 months, p-value < 0.05). Furthermore, patients with a first-line treatment PFS of less than 6 months may potentially benefit from subsequent treatment with pyrotinib (median PFS: 7.467 vs. 3.000, p-value = 0.0490). CONCLUSIONS: In the first-line treatment of HER2-Mutant LUAD, regimens involving combinations like chemotherapy + ICIs, chemotherapy + bevacizumab, and pyrotinib may confer enhanced survival advantages compared to chemotherapy. Nevertheless, no significant distinctions were observed among these three treatment strategies, underscoring the imperative to identify biomarkers for the discerning selection of suitable therapeutic modalities. Moreover, patients with suboptimal response to first-line treatment may potentially derive more benefit from pyrotinib.

PD-1 blockade enhances the effect of targeted chemotherapy on locally advanced pMMR/MSS colorectal cancer.

BACKGROUND: Patients with DNA mismatch repair-proficient/microsatellite stable (pMMR/MSS) colorectal cancer (CRC), which accounts for 85% of all CRC cases, display a poor respond to immune checkpoint inhibitors (i.e., anti-PD-1 antibodies). pMMR/MSS CRC patients with locally advanced cancers need effective combined therapies. METHODS: In this pilot study, we administered six preoperative doses of each 2-week cycle of the anti-PD-1 antibody sintilimab (at a fixed dose of 200 mg), oxaliplatin, and 5-FU/CF (mFOLFOX6) combined with five doses of bevacizumab (the number of doses was reduced to prevent surgical delays) to patients with cT4NxM0 colon or upper rectal cancers. And radical surgery was performed approximately 2 weeks after the last dose of neoadjuvant therapy. The primary endpoint was a pathologic complete response (pCR). We also evaluated major pathologic response (MPR, ≤10% residual viable tumor), radiological and pathological regression, safety, and tumor mutation burden (TMB), and tumor microenvironment (TME) characteristics. RESULTS: By the cutoff date (September 2023), 22 patients with cT4NxM0 pMMR/MSS colon or upper rectal cancers were enrolled and the median follow-up was 24.7 months (IQR: 21.1-26.1). All patients underwent R0 surgical resection without treatment-related surgical delays. pCR occurred in 12 of 22 resected tumors (54.5%) and MPR occurred in 18 of 22 (81.8%) patients. At the cutoff date, all patients were alive, and 21/22 were recurrence-free. Treatment-related adverse events of grade 3 or higher occurred in of 2/22 (9.1%) patients. Among the pCR tumors, two were found to harbor POLE mutations. The degree of pathological regression was significantly greater than that of radiological regression (p = 1.35 × 10-8). The number of CD3+/CD4+ cells in the tumor and stroma in pretreated biopsied tissues was markedly lower in pCR tumors than in non-pCR tumors (p = 0.038 and p = 0.015, respectively). CONCLUSIONS: Neoadjuvant sintilimab combined with bevacizumab and mFOLFOX6 was associated with few side effects, did not delay surgery, and led to pCR and non-pCR in 54.5% and 81.8% of the cases, respectively. Downregulation of CD3/CD4 expression in the tumor and stroma is related to pCR. However, the molecular mechanisms underlying PD-1 blockade-enhanced targeted chemotherapy require further investigation.

Safety/efficacy of atezolizumab + bevacizumab during anti-platelet/anticoagulation therapy in unresectable hepatocellular carcinoma.

BACKGROUND AND AIMS: This study aimed to determine the safety and efficacy of atezolizumab + bevacizumab therapy in hepatocellular carcinoma patients receiving anti-platelet agents or anticoagulants. METHODS: Patients were divided into those using (IM out) and those not using (IM in) anti-platelet agents or anticoagulants, who violated the exclusion criteria of the IMbrave150 trial, and were retrospectively examined. RESULTS: The study included 185 patients (IM in: 157; IM out: 28). For first-line treatment, progression-free survival was 184 days for IM in and 266 days for IM out (p = .136). Overall survival was 603 days for IM in and not reached for IM out (p = .265), with no significant between-group difference. Similarly, there were no significant between-group differences in progression-free survival or overall survival for later-line treatment. Haemorrhagic adverse events of ≥grade 3 were observed in 11 IM in patients and 3 IM out patients. No significant factors associated with haemorrhagic adverse events of ≥grade 3 were identified in the multivariate analysis including IM out classification, whose p value was .547. Regarding thrombotic/embolic adverse events in the IM out group, one case of exacerbation of portal vein thrombosis was observed. No deaths were directly attributable to bleeding events or exacerbations of thrombosis. CONCLUSION: Atezolizumab + bevacizumab therapy shows similar safety and efficacy in patients receiving and those not receiving anti-platelet agents or anticoagulants; therefore, it can be considered for patients with hepatocellular carcinoma receiving anti-platelet agents or anticoagulants.

Safety and Patient-Reported outcomes of atezolizumab plus chemotherapy with or without bevacizumab in stage IIIB/IV non-squamous non-small cell lung cancer with EGFR mutation, ALK rearrangement or ROS1 fusion progressing after targeted therapies (GFPC 06-2018 study).

BACKGROUND: In an open-label multicenter non-randomized non-comparative phase II study in patients with stage IIIB/IV non-squamous non-small cell lung cancer (NSCLC), oncogenic addiction (EGFR mutation or ALK/ROS1 fusion), with disease progression after tyrosine-kinase inhibitor and no prior chemotherapy (NCT04042558), atezolizumab, carboplatin, pemetrexed with or without bevacizumab showed some promising result. Beyond the clinical evaluation, we assessed safety and patient-reported outcomes (PROs) to provide additional information on the relative impact of adding atezolizumab to chemotherapy with and without bevacizumab in this population. MATERIALS: Patients received platinum-pemetrexed-atezolizumab-bevacizumab (PPAB cohort) or, if not eligible, platinum-pemetrexed-atezolizumab (PPA cohort). The incidence, nature, and severity of adverse events (AEs) were assessed. PROs were evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-Core 30 and EORTC QLQ-Lung Cancer 13). RESULT: Overall, 68 (PPAB) and 72 (PPA) patients were evaluable for safety. Grade 3-4 AEs occurred in 83.8% (PPAB) and 63.9% (PPA). Grade 3-4 atezolizumab-related AEs occurred in 29.4% and 19.4%, respectively. Grade 3-4 bevacizumab-related AEs occurred in 36.8% (PPAB). Most frequent grade 3-4 AEs were neutropenia (19.1% in PPAB; 23.6% in PPA) and asthenia (16.2% in PPAB; 9.7% in PPA). In PPAB, we observed a global stability in global health security (GHS) score, fatigue and dyspnea with a constant tendency of improvement, and a significant improvement in cough. In PPA, we observed a significant improvement in GHS score with a significant improvement in fatigue, dyspnea and cough. At week 54, we observed an improvement from baseline in GHS score for 49.2% of patients. In both cohorts, patients reported on average no clinically significant worsening in their overall health or physical functioning scores. CONCLUSION: PPAB and PPA combinations seem tolerable and manageable in patients with stage IIIB/IV non-squamous NSCLC with oncogenic addiction (EGFR mutation or ALK/ROS1 fusion) after targeted therapies.

Neoadjuvant chemotherapy with bevacizumab for locally advanced vulvar cancer.

OBJECTIVES: External beam radiation with sensitizing platinum is the recommended therapy for locally advanced vulvar cancers not amenable to curative surgery and is associated with considerable acute and chronic side effects. Radical vulvectomy post-radiation for persistent disease is often compromised with poor wound healing. We describe clinical outcomes for patients who received neoadjuvant chemotherapy plus bevacizumab followed by radical vulvectomy for locally advanced vulvar cancer. METHODS: We performed retrospective analyses of all patients at our institution who underwent radical vulvectomy from January 2015 to November 2023. Of 113 patients, 13 patients underwent neoadjuvant chemotherapy. Demographics and clinicopathologic data were extracted, and descriptive statistical analyses were performed. Cases with neoadjuvant chemotherapy plus bevacizumab were further evaluated for response, adverse effects, and survival. RESULTS: Neoadjuvant chemotherapy was administered to 13 patients with stage II-IV disease that involved the urethra, vagina, or anus. Lesion sizes ranged from 4 to 20 cm (median 7 cm). Patients received 2-6 cycles of carboplatin or cisplatin, paclitaxel, and bevacizumab. Nine (69.2%) patients had partial pathologic responses, and four patients had complete responses. All patients had negative surgical margins. Ten (76.9%) patients had radiographic evidence of inguinal lymph node metastasis prior to neoadjuvant chemotherapy, and four had residual nodal disease. Only one patient developed a superficial groin seroma. Three patients developed recurrence, two locally and one distant, and there was one death. The median follow-up was 23 months (range 6-84 months). CONCLUSIONS: Neoadjuvant chemotherapy using combination platinum/paclitaxel/bevacizumab was efficacious for locally advanced vulvar cancer, resulting in complete resections, negative margins, and excellent wound healing. A multi-institutional phase II trial is warranted to validate these findings.
