A number of therapeutic options are available for the treatment of advanced kidney cancer, including targeted therapy, immunotherapy, and nephrectomy. Choice of therapy for advanced kidney cancer is guided by risk stratification. Immunotherapy combinations are generally superior to vascular endothelial growth factor -based monotherapy, and overall survival rates continue to increase substantially. With new systemic therapy options, additional improvements have been noted in durable responses to treatment and in quality of life. Nephrectomy remains an important consideration in selected patients, particularly those with minimal burden of metastatic disease. Managing the adverse events of treatment of advanced kidney cancer requires close attention and multidisciplinary collaboration.

SummaryTwenty patients with unresectable hepatocellular carcinoma (HCC) were followed up to 5 years after transarterial radiotherapy with 90Y-resin particles. Diagnostic radioembolizations of 99mTc-macroaggregates facilitated scintigraphic assessment of activity distribution, dose evaluation and final procedural verification. The overall survival rates were 56, 38 and 14% (after 1, 2 and 3 years, resp.). Patients with unifocal HCC and a single feeding artery (n = 7) even presented 83, 67 and 40% (2 alive after 2.75 and 4 years). With multiple arteries (n = 7), the longest survival was 26 months. Patients with multifocal HCC survived up to 33 months after selective radioembolization. Quality of life was improved in all. Survival was positively correlated with absorbed dose but residual/recurrent tumour occurred even after ≥300 Gy. Post-treatment symptoms were minimal (35 applications), pulmonary shunt rates were correctly predicted and pulmonary complications avoided.

Background: the presence of liver metastasis in colorectal cancer (CRC) remains one of the most significant prognostic factors. Objective: systematically review the results of studies evaluating the benefit of adding bevacizumab to a normal chemotherapy regime in the survival of patients with colorectal-cancer liver metastasis (CRLM). Search methods: Pubmed and Google Scholar databases were searched for eligible articles (from inception up to the 2 April 2019). Inclusion criteria: studies including patients with CRLM receiving anti-vascular endothelial growth factor (VEGF; bevacizumab) as treatment, overall survival as an outcome; regarding language restrictions, only articles in English were accepted. Main results: Eleven studies met the inclusion criteria. In 73% of these cases, chemotherapy with bevacizumab was an effective treatment modality for treating CRLM, and its administration significantly extended both overall survival (OS) and/or progression-free survival (PFS). Nevertheless, three articles showed no influence on survival rates of bevacizumab-associated chemotherapy. Author conclusions: It is necessary to standardize methodologies that aim to evaluate the impact of bevacizumab administration on the survival of patients with CRLM. Furthermore, follow-up time and the cause of a patient’s death should be recorded, specified, and cleared in order to better calculate the survival rate and provide a comparison between the produced literature.

AbstractBackground:This review evaluates whether brachytherapy can be considered as an alternative to whole breast irradiation (WBI) using criteria such as local recurrence rates, overall survival rates and quality of life (QoL) factors. This is an important issue because of a decline in local recurrence rates, suggesting that some women at very low risk of recurrence may be incurring the negative long-term side effects of WBI without benefitting from a reduction in local recurrence and greater overall survival. As such, the purpose of this literature review is to evaluate whether brachytherapy is a credible alternative to external beam radiation with a particular focus on the impact it has on patient QoL.Methods:The search terms used were devised by using the Population Intervention Comparison Outcome framework, and a literature search was carried out using Boolean connectors and Medical Subject Headings in the PubMed database. The resultant articles were manually assessed for relevance and appraised using the Scottish Intercollegiate Guidelines Network tool. Additional papers were sourced from the citations of articles found using the search strategy. Government guidelines and regulations were also used following a manual search on the National Institute for Health and Care Excellence website. This process resulted in a total of 30 sources being included as part of the review.Results:Three types of brachytherapy were the foundation for the majority of the papers found: interstitial multi-catheter brachytherapy, intra-cavity brachytherapy and permanent seed implantation. The key themes that arose from the literature were that brachytherapy is equivalent to WBI both in terms of 5-year local recurrence rates and overall survival rates at 10–12 years. The findings showed that brachytherapy was superior to WBI for some QoL factors such as being less time-consuming and equal in terms of others such as breast cosmesis. The results did also show that brachytherapy does come with its own local toxicities that could impact upon QoL such as the poor breast cosmesis associated with some brachytherapy techniques.Conclusion:In conclusion, brachytherapy was deemed a safe or acceptable alternative to WBI, but there is a need for further research on the long-term local recurrence rates, survival rates and quality of life issues as the volume of evidence is still significantly smaller for brachytherapy than for WBI. Specifically, there needs to be further investigation as to which patients will benefit from being offered brachytherapy and the influence that factors such as co-morbidities, performance status and patient choice play in these decisions.

Abstract Background Vascular endothelial growth factor (VEGF) plays an important role in angiogenesis and progression of cancer, and blood level of VEGF has been known to predict of outcome in several types of cancer. However, the impact of blood VEGF levels on prognosis of diffuse large B-cell lymphoma (DLBCL) has not been fully elucidated. Here we investigated the prognostic implication of circulating VEGF levels in patients with DLBCL. Patients and Methods The study involved 127 DLBCL patients treated by rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) at National Cancer Center, Korea. Both serum and plasma of the patients were obtained at diagnosis. VEGF were measured using ELISA kit (R&D systems) according to manufacturer’s guidance. We investigated the correlation between clinical parameters and blood VEGF levels. Survival rates and hazard ratios (HRs) in terms of risk for overall survival were determined using Kaplan-Meier method and Cox proportional hazard regression analysis. Results The median patient age was 56 years, and 75 (59%) patients were men. Clinical characteristics and international prognostic index (IPI), including age, performance, lactate dehydrogenase (LDH), Ann Arbor stage and extranodal involvement were evaluated. The mean (±SD) value of serum and plasma VEGFs were 713 (±599.8) and 107 (±164.4) pg/mL, and they were correlated as r=0.61 (p<0.001). Both serum and plasma VEGF showed the significant (p<0.01) correlation with serum LDH level, Ann Arbor stage and multiple extranodal involvement, but not with age, gender nor performance. IPI showed strong prediction for prognosis in our data set (HR 3.80, 95%CI 1.64-8.81, p=0.02), and the VEGF levels of high/high-intermediate IPI group were significantly higher than those of low/low-intermediate group [serum VEGF 1088(±838.0) and 557(±377.2), p<0.001 and plasma VEGF 79(±131.6) and 176(±212.2), p=0.002]. With the median follow-up of 44 months, high serum VEGF levels (higher than the median) were significantly associated with short survival (HR 2.74, 95%CI 1.13-6.60, p=0.025), though the plasma VEGF levels did not show the association similar to the serum samples (HR 1.40, 95%CI 0.63-3.12, p=0.414). The patients with higher serum VEGF than the median value showed significantly lower survival rate compared to the low group (3-year survival rates, 68.6% vs. 85.6%, p=0.019). Conclusion These findings suggest that high serum VEGF levels can predict poor clinical outcome in patients with DLBCL. This study also represents the different type of specimen for VEGF measurement affected the results. We might have to select adequate specimen type for VEGF measurement, although further validation in large cohort and mechanism studies for this data are warranted.

20506 Background: Vascular endothelial growth factor (VEGF) plays an important role in many tumors including SAR. Because of the known efficacy of PLD in SAR and the presumed importance of VEGF in SAR, we have treated SAR patients with PLD-B. It is possible that the addition of B to PLD might alter the toxicity profile. The toxicities of this combination are not well described. Methods: To better define the toxicity of the combination of PLD-B in SAR, we reviewed our experience with PLD-B in patients treated between 2004 and 2006. Results: We identified 20 patients with SAR treated with PLD-B at our institution. There were 9 men and 11 women, with a median age of 47.5 years (range 23–77). Ten patients initiated therapy with PLD q28 days at a median dose of 45 mg/m2 (range 45–50), and 10 q14 days at a median dose of 21.2 mg/m2 (range 20–25), in combination with B at 5 mg/kg q14 days. A median of 5 cycles was given (range 1–15). Dose delay was required in 3 patients for the second cycle, and dose reduction was required in 9 patients by cycle 3. Of the 10 patients starting with monthly PLD, 7 were changed to q14 day PLD by cycle 4. Mucositis and skin toxicity were the dose limiting toxicities (DLT) in 14/20 patients, and myelosuppression was the DLT in 1/20 patients. Nine patients were felt to have clinical benefit; 3 had a PR and 6 had SD. Notably, 2/4 recurrent Ewing sarcoma patients had symptomatic improvement and at least SD for 10 and 11 months, respectively, with minor toxicity allowing a good quality of life. Conclusions: This report describes the toxicity profile of PLD-B in 20 patients with SAR. The toxicities observed were similar to those seen with PLD alone, however, these toxicities appeared more pronounced with the addition of B. Since VEGF is important for wound healing, the known effects of B on this process may contribute to more skin and mucosal toxicity of PLD at a given dose. Future studies of PLD-B should consider the potential of increased mucosal and skin toxicity. The use of q14 day PLD to allow more control over toxicity is suggested; a maximal starting dose of 20 mg/m2 is reasonable, although dose reduction will be common due to skin or mucosal toxicity. This combination can be given with limited toxicity, and meaningful responses were observed in recurrent sarcomas, including 2/4 Ewing sarcomas. No significant financial relationships to disclose.

6048 Background: Patients with recurrent and refractory epithelial ovarian cancer (EOC) have dismal outcomes. We evaluated a combination of oral metronomic therapy in platinum refractory EOC vis-à-vis angiogenic marker expression and its impact on patient reported outcomes. Methods: Between October 2017 and September 2019, 75 patients were randomized to receive etoposide (VP-16) (50 mg daily for 14 days) cyclophosphamide (50 mg daily for 28 days) (Arm A, n = 38) or etoposide (VP-16) (50 mg daily for 14 days) cyclophosphamide (50 mg daily for 28 days) and pazopanib (400 mg daily 28 days) every 28 days (Arm B, n = 37). Eligibility criteria included histopathological diagnosis of EOC, platinum refractory disease and ECOG performance status 0-2. Primary endpoint was serological progression free survival (PFS) as defined by Rustin criteria. Quality of Life (QoL) (evaluated using the EORTC QLQC30 and OV 28 questionnaires) and serum vascular endothelial growth factor (VEGF) were ascertained at baseline and after 3rd and 6th cycle. Intention to treat analysis was done. Results: Baseline characteristics were well matched in 2 arms. At a median follow up 14.4 months (95% CI 13.2-15.7), the median serological PFS is better for patients in Arm B 5.1 months (95%CI 3.13-10.33) compared to 3.4 months (95%CI 3-6.53) in arm A ( P= 0.045). Median overall survival (OS) is not reached in arm B versus 11.2 months (95%CI 5.66-NR) in arm A (P= 0.032). Disease progression was seen in 42.1% (n = 16) in Arm A versus 40.5 %(n = 15) in arm B ( P= 0.40). Sixteen patients are maintaining response. Mucositis (29.7% n = 11) and fatigue (13.5%, n = 5) were more in the pazopanib-containing arm ( P= 0.36). Serum VEGF demonstrated significant decline with subsequent cycles of therapy {median values (range): Arm A, baseline; 466.0 pg/mL(123.9-1930) vs. 6 cycles; 92.05pg/ mL(42.34-279.5) P< 0.0001; Arm B, baseline; 382.0 pg/mL(49.44-2054.0) vs 6 cycles; 119.7 pg/mL(18.20-367.5) P= 0.013} without any difference between the two arms ( P= 0.18). QoL symptom scales in both QLQC 30 and OV 28 questionnaires indicated small but significant improvement in pazopanib arm ( P= 0.02) without differences in global (p = 0.96) and physical functioning scales. ( P= 0.68). Conclusions: Addition of pazopanib to etoposide and cyclophosphamide resulted in improvement in serological PFS and OS with a well-tolerated toxicity profile and modest improvement in QoL.Serum VEGF expression requires validation in a larger cohort.

Glioblastoma are one of the mostly vascularized tumors and are histologically characterized by abundant endothelial cell proliferation. Vascular endothelial growth factor (VEGF) is responsible for a degree of vascular proliferation and vessel permeability leading to symptomatic cerebral edema. Initial excitement generated from the impressive radiographic response rates has waned due to concerns of limited long-term efficacy and the promotion of a treatment-resistant phenotype. Reasons for the discrepancy between high radiographic response rates and lack of survival benefit have led to a focus on identifying potential mechanisms of resistance to antiangiogenic therapy. However, equally important is the need to focus on identification of basic mechanisms of action of this class of drugs, determining the optimal biologic dose for each agent and identify the effect of antiangiogenic therapy on oxygen and drug delivery to tumor to optimize drug combinations. Finally, alternatives to overall survival (OS) need to be pursued using the application of validated parameters to reliably assess neurologic function and quality of life.
