The use of tyrosine kinase inhibitors (TKIs) in the treatment of solid tumors is the expected standard of care for many types of tumors. Since the description of signal transduction pathways, followed by the development of small molecules designed to inhibit those pathways, there has been significant improvement not only in progression-free survival and overall survival but also in aiming toward chemotherapy-free treatment of solid tumors to maximize quality of life. This article reviews available TKIs and discusses toxicity, dosing, and resistance.

224 Background: Stromal tumors of the digestive tract are uncommon malignant diseases, and are subclassified as leiomyosarcomas and gastrointestinal stromal tumors (GIST) depending on the molecular expression of CD117 (KIT). GISTs represent 1% of malignant tumors affecting this anatomical site. Located diseases are reasonably well controlled by surgical resection and several criteria define the need for adjuvant therapy. In the case of metastatic disease a poor prognosis has been reported with systemic treatment based on chemotherapy. Recently, significant advances have been shown since Tyrosine – kinase inhibitors were introduced, with median overall survival close to 5 years. Unfortunately in Mexico, even though the therapy has been long used there are no published data of the experience in the treatment of these tumors. Methods: We used an electronic data base to obtain clinical, radiological and histological data of patients diagnosed with GIST and treated in the oncological center of the Mexican Institute of Social Security, patients were subclassified by stage, symptoms at diagnosis as well as the initial and subsequent systemic treatment. Finally we made an analysis for progression free survival and overall survival identifying prognostic factors. Results: We obtained information of 71 patients with metastatic, nonresectable or recurrent GIST, treated with a TKI, we observed a predominant relation for women (60.4%), with median age of 58 years. Stage at diagnosis was predominantly metastatic (46.5%) most frequently affected sites were lung, liver and retroperitoneum. Median progression free survival was 23.6m and overall survival was 81.3 months. All patients were initially treated with imatinib at a dose of 400mg per day. Treatment was well tolerated in most cases. Conclusions: Metastatic GIST evaluated in our center shows a different affection in gender and age, our population shows a different response to TKI’s, than reported in other series with superior overall survival, Poor prognosis is associated with lung affection. Biological studies will be started for the molecular evaluation of these tumors.

Abstract Activation of the EVI-1 oncogene has been reported in acute myeloid leukemia, chronic myeloid leukemia (CML) in blast crisis, and less commonly, in chronic-phase CML patients. We screened an unselected cohort of 75 chronic-phase CML patients who had failed imatinib for expression of EVI-1 and sought a correlation with subsequent outcome on the second-generation tyrosine kinase inhibitors dasatinib (n = 61) or nilotinib (n = 14). The 8 patients (10.7%) who expressed EVI-1 transcripts detectable by real-time polymerase chain reaction had significantly lower event-free survival, progression-free survival, and overall survival than patients with undetectable transcript. The predictive value of EVI-1 expression was validated in an independent cohort. In a multivariate analysis, EVI-1 expression status and the best cytogenetic response obtained on imatinib were the only independent predictors for overall survival, progression-free survival, and event-free survival. Our data suggest that screening for EVI-1 expression at the time of imatinib failure may predict for response to second-line TKI therapy and consequently aid clinical management.

Objective: We aimed to evaluate the role of intra-tumoral CXCR1 expression in predicting prognosis and treatment response in metastatic clear-cell renal cell carcinoma patients receiving tyrosine kinase inhibitors. Materials and methods: Patients with metastatic clear-cell renal cell carcinoma presented between February 2018–December 2019 were studied for the CXCR1 expression in tumor tissues before starting tyrosine kinase inhibitors. Primary outcome measure was progression-free survival. Secondary outcome measures included overall survival and prediction of treatment response. Results: The study included 35 patients with a mean age of 53.6±9.6 years. At a mean follow-up of 12.2±4.1 months, 17 (48.6%) patients had disease progression including eight (22.9%) deaths. Patients with high CXCR1 expression, compared to those with low CXCR1 expression, had a significantly shorter 12-month progression-free survival (35.4% vs 77.9%, p=0.01) and an insignificant impact on 12-month overall survival. The CXCR1 expression scores significantly differed between patients with progressive and nonprogressive disease (20.1 vs 15.1, p=0.01) and patients with high CXCR1 expression had a reduced benefit from tyrosine kinase inhibitors. The multivariate Cox regression analysis showed CXCR1 expression as a significant predictor of progression-free survival. Conclusion: High intra-tumoral CXCR1 expression before tyrosine kinase inhibitors can be an independent prognostic factor for progression-free survival and predictor of reduced benefit in patients with metastatic clear-cell renal cell carcinoma. Level of evidence: Level 2b.

Abstract Background: Hypothyroidism as a predictive factor represent highly controversial in patients with metastatic renal cell carcinoma (mRCC) with tyrosine kinase inhibitors-induced (TKI-induced) hypothyroidism. we aimed to evaluate the predictive value of TKI-induced hypothyroidism for progression-free survival (PFS) in patients with mRCC.Methods: PubMed, Web of Science and Cochrane Library databases were searched with the keywords of "renal cell carcinoma", "hypothyroidism", "tyrosine kinase inhibitor", "sunitinib", "axitinib", "sorafenib" and "pazopanib" until September 2019. The hazard ratio (HR) and 95% confidence interval (CI) of extracted from progression-free survival (PFS) were statistically analyzed by STATA15.1 software. Heterogeneity was assessed by I²value. Publication bias was appraised by the funnel chart, Egger's and Begg's tests.Results: Eighteen studies with more than 1300 patients were included in this meta-analysis. The result demonstrated that TKI-induced hypothyroidism was an effective predictor of longer PFS (HR=0.57,95%CI:0.49-0.66, P<0.001, I²=34.4%) in patients with mRCC. No significant publication bias was detected.Conclusions: Our analysis harvested from currently available clinical evidence shows that TKI-induced hypothyroidism expressed longer PFS, compared with euthyroidism, among patients with mRCC treated with "sunitinib", "axitinib", "sorafenib" and "pazopanib".

e16117 Background: Lymphopenia is associated with toxicity and clinical outcomes in several types of cancer. Decrease in absolute lymphocyte count (ALC) has been observed in the treatment with sunitinib. Objective: characterize lymphopenia ( < 1000/µL) associated with tyrosine kinase inhibitors in patients with metastatic renal cell carcinoma (mRCC) and its relation to progression free survival (PFS). Methods: A retrospective review of the charts was performed in patients with sunitinib and/or sorafenib between April 2000 and May 2017 in Guatemalan Social Security Institute (IGSS). The Kaplan-Meier models, the Cox regression and the log-rank test are within the groups for progression-free survival. Results: Eighty-nine patients were analyzed, 56 men and 33 women. The age groups < 50 from 51 to 75 and > 75 being these 19, 34 and 34 respectively. Regarding treatment received 56 patients received sunitinib and 47 sorafenib. Lymphopenia was found in 55% and 8% of the treated with sunitinib and sorafenib, respectively (p < 0.001). Focusing on patients treated with sunitinib for all subsequent analyzes, the median PFS was 11 months (95% CI, 6-19). The median PFS was 21 months (95% CI, 11-25) for patients who will not develop lymphopenia compared to 4 months (95% CI, 3-8) in patients with lymphopenia (p = 0, 0001). Conclusions: Lymphopenia related to sunitinib is associated with a decrease in PFS in mRCC. The decrease in lymphocytes can be used as a prognostic biomarker for patients treated with sunitinib in this context. [Table: see text]

AbstractNotwithstanding regulatory approval of lenvatinib and sorafenib to treat radioiodine-refractory differentiated thyroid carcinoma (RAI-R DTC), important questions and controversies persist regarding this use of these tyrosine kinase inhibitors (TKIs). RAI-R DTC experts from German tertiary referral centers convened to identify and explore such issues; this paper summarizes their discussions. One challenge is determining when to start TKI therapy. Decision-making should be shared between patients and multidisciplinary caregivers, and should consider tumor size/burden, growth rate, and site(s), the key drivers of RAI-R DTC morbidity and mortality, along with current and projected tumor-related symptomatology, co-morbidities, and performance status. Another question involves choice of first-line TKIs. Currently, lenvatinib is generally preferred, due to greater increase in progression-free survival versus placebo treatment and higher response rate in its pivotal trial versus that of sorafenib; additionally, in those studies, lenvatinib but not sorafenib showed overall survival benefit in subgroup analysis. Whether recommended maximum or lower TKI starting doses better balance anti-tumor effects versus tolerability is also unresolved. Exploratory analyses of lenvatinib pivotal study data suggest dose-response effects, possibly favoring higher dosing; however, results are awaited of a prospective comparison of lenvatinib starting regimens. Some controversy surrounds determination of net therapeutic benefit, the key criterion for continuing TKI therapy: if tolerability is acceptable, overall disease control may justify further treatment despite limited but manageable progression. Future research should assess potential guideposts for starting TKIs; fine-tune dosing strategies and further characterize antitumor efficacy; and evaluate interventions to prevent and/or treat TKI toxicity, particularly palmar-plantar erythrodysesthesia and fatigue.
