Introduction Regorafenib, a receptor tyrosine kinase inhibitor, is a routinely used targeted agent in the current treatment of patients with refractory metastatic colorectal carcinoma (mCRC). The aims of this study were to detect the presence of bowel wall edema during regorafenib treatment via computed tomography (CT) and to assess the relationship between survival and regorafenib-induced bowel wall edema in patients with mCRC receiving regorafenib. Patients and methods We retrospectively evaluated the presence of bowel wall edema on CT of 25 mCRC patients who received regorafenib and analyzed its relationship with progression free survival (PFS) and overall survival (OS). Results Among the 25 patients, 25 had small bowel wall edema (SBWE) and 14 had large bowel wall edema (LBWE) on at least one CT examination. The median SBWE value was 4.85 milimeters (mm). Of the 25 patients, 14 had SBWE ≤4.85 mm and 11 had SBWE >4.85 mm. Regorafenib intolerance was significantly higher at SBWE >4.85 mm patients (p = 0.03). The median PFS was 4.6 months (95% CI: 2.4–6.8) and median OS was 9.3 months (95% CI: 3.1–15.4). Median PFS and OS were shorter in patients with SBWE > 4.85 mm than in those with ≤4.85 mm, but not statistically significant (median PFS: 3.9 vs 4.6 months, p: 0.523; median OS: 5.6 vs 9.3 months, p: 0.977). Conclusions Regorafenib caused SBWE in patients with mCRC. Patients who developed more SBWE had a higher regorafenib intolerance and a shorter survival. Further studies are needed to confirm the predictor value of SBWE on the survival outcomes of patients with mCRC receiving regorafenib.

Idiopathic pulmonary fibrosis (IPF) is a common interstitial lung disease (ILD) caused by environmental exposures, infections, or traumatic injuries and subsequent epithelial damage. Since IPF is a progressively fatal disease without remission, treatment is both urgent and necessary. The two medications indicated solely for treatment include the tyrosine kinase inhibitor nintedanib (Ofev®) and the anti-fibrotic agent pirfenidone (Esbriet®). This chapter discusses in detail the current treatment options for clinical management of IPF, specifically the mentioned two pharmacotherapeutic agents that decrease physiological progression and likely improve progression-free survival. The chapter also discusses the evolution of drug therapy in IPF management and the drawbacks and limitations learned throughout historical trials and observational studies.

<b><i>Introduction:</i></b> This study compared clinical outcomes of 2nd- and 3rd-line regorafenib in patients with unresectable hepatocellular carcinoma. <b><i>Methods:</i></b> In this retrospective cohort study, 48 patients were treated with regorafenib for unresectable hepatocellular carcinoma. Thirty-five and 13 patients were initiated on 2nd- and 3rd-line therapy, respectively. We assessed the responses to and safety of the therapy. <b><i>Results:</i></b> There were no statistically significant differences in clinical characteristics at the start of 2nd- or 3rd-line regorafenib therapy. The overall response rate of 2nd- and 3rd-line regorafenib was 20 and 8%, respectively. The disease control rate was 57 and 54%, respectively. Median overall survival (mOS) from the start of 2nd-line regorafenib was 17.5 months. mOS from the start of 3rd-line regorafenib was not obtained. Median progression-free survival of 2nd- and 3rd-line regorafenib was 4.9 and 2.3 months, respectively. mOS from 1st-line therapy with tyrosine kinase inhibitor plus sorafenib-regorafenib-lenvatinib was 29.5 months; that with lenvatinib-sorafenib-regorafenib was not obtained. Patients on 3rd-line therapy tended to have better Child-Pugh scores and tumor factors at the start of 1st-line therapy than other patients. <b><i>Conclusion:</i></b> Patients on 2nd- and 3rd-line regorafenib showed favorable responses. Good Child-Pugh scores and tumor factors may be associated with a better response rate and OS.

278 Background: Tivozanib (T) is a potent and highly selective VEGF receptor (R) tyrosine kinase inhibitor in clinical development for RCC. Axitinib is also a potent and selective VEGF-R inhibitor now commonly part of front-line aRCC treatment. The activity of T after axitinib has not been previously defined. The activity of T after prior therapy types including axitinib is of clinical relevance. Methods: The pivotal TIVO-3 study enrolled subjects with mRCC who failed 2 or 3 prior systemic regimens, one of which included a VEGFR TKI, stratified by IMDC risk category and type of prior therapy (two TKIs; TKI plus checkpoint; TKI + other) then randomized in a 1:1 ratio to T or S. The primary objective of the overall trial was to compare progression free survival (PFS) by blinded independent radiological review. Patients with prior axitinib received as monotherapy in the second or third line setting and other predefined subgroups were reviewed for outcome with T. Results: Patients treated with T after prior axitinib had a PFS of 5.5 months and an ORR of 13% compared to 3.7 months and 8% for patients treated with S. Other subgroups are presented in the table below. Clinical trial information: NCT02627963 . Conclusions: Tivozanib improved PFS vs. sorafenib in patients who have progressed after multiple VEGFR-TKIs, including patients with prior second or third line axitinib treatment. These results suggest differential activity from tivozanib and axitinib despite both being potent and selective VEGF-R inhibitors. [Table: see text]

8534 Background: Cancer Associated Macrophage-Like cells (CAMLs) are circulating stromal cells in the blood of patients (pts) with solid tumors that are phagocytic macrophages that may represent the inflammatory state of the tumor microenvironment. Previously, we demonstrated CAMLs ≥50µm after chemo-radiation therapy (CRT) in NSCLC is associated with worse progression free survival (PFS) and overall survival (OS). We also showed that PDL1 expression in CAMLs is dynamic & can change with CRT, difficult to assess with repeat biopsies, but possible with liquid biopsy. For this study we evaluated whether CAML properties can predict response to CRT with/without immunotherapy (IMT) agents in unresectable NSCLC. Methods: A single blind multi-year prospective study was undertaken to test the relationship of PDL1 expression and ≥50µm CAML size to PFS/OS in NSCLC, pre and post CRT with (n = 96) and without (n = 72) anti-PDL1/PD1 IMT. This included atezolizumab (prospective single arm NCT02525757) n = 39, durvalumab n = 52 or pembrolizumab n = 5 both after 2018 FDA approval. We recruited 168 pts with pathologically confirmed unresectable NSCLC prior to CRT. Blood samples 15 mL were taken at baseline (BL), CRT completion (T1), and ̃1 month after CRT (T2) (with n = 96 or without n = 72 IMT). Blood was filtered by CellSieve filtration and CAMLs quantified for size ( < 49 µm or ≥50 µm) and PDL1 expression to evaluate PFS and OS hazard ratios (HRs) by censored univariate and multivariate analysis at 24 months. Results: CAMLs were found in 90% of all samples, average 5.8 CAMLs/15mL. At BL, ≥50µm CAMLs did not predict PFS in CRT/IMT pts (HR 1.6, p = 0.220) nor CRT alone (HR 1.3, p = 0.593). However, after completion of CRT (T1) ≥50µm CAMLs predicted PFS in CRT/IMT pts (HR 2.7, p = 0.003) and CRT alone (HR 2.5, p = 0.015). In primary tumor biopsies, PDL1 expression > 1% did not predict CRT/IMT response (PFS HR 1.8, p = 0.262 & OS HR 2.3, p = 0.158). At BL, high CAML PDL1 did not predict PFS in CRT/IMT pts (HR 1.4, p = 0.427) nor CRT alone (HR 1.1, p = 0.982). Further, at CRT completion (T1), high CAML PDL1 only trended for better PFS in CRT/IMT pts (HR 1.7, p = 0.137), but not CRT alone (HR 1.1, p = 0.972). At T2, however, pts with continuously high CAML PDL1 had significantly better PFS with IMT (HR 3.2, p = 0.002) vs CRT alone (HR 1.4, p = 0.616). While ≥50µm CAMLs at BL did not predict 24 month progression, ≥50 µm CAMLs after CRT (with or without 1 cycle of anti-PDL1 IMT) was 84% accurate at predicting progression. Further subtyping and analysis is ongoing to evaluate OS and PDL1 in the CAML populations. Conclusions: Our data suggests that in unresectable NSCLC, ≥50 µm CAMLs after completion of CRT is prognostic regardless of IMT use. PDL1 expression in CAMLs also appears to predict for response to consolidated IMT after CRT. Additional studies are needed to validate these findings.

e16567 Background: ICI/TKI combinations are a new standard of care for the initial treatment (tx) of mRCC. Efficacy and toxicity of such combination regimens beyond the first-line (1L) setting remain unknown. Methods: We retrospectively reviewed charts for adult patients (pts) receiving an ICI/TKI combination in any line of tx for mRCC of any histology at one of two academic centers as of May 1, 2020. ICIs included pembrolizumab (Pm), nivolumab (Ni), ipilimumab (Ip), or avelumab (Av); TKIs included sunitinib (Su), axitinib (Ax), pazopanib (Pz), lenvatinib (Ln), or cabozantinib (Ca). Clinical data including pt demographics, histology, International mRCC Database Consortium (IMDC) risk group, tx history, and ICI/TKI tx and toxicity details were recorded. Outcomes included objective response rate (ORR), median progression-free survival (mPFS), and safety, analyzed via descriptive statistics and the Kaplan-Meier method. Results: Of 85 pts, 69 (81%) were male and 67 (79%) had clear cell histology. IMDC risk was favorable (24%), intermediate (54%), poor (20%), and unknown (2%). 39% had ICI/TKI tx in the 1L setting. ICI/TKI regimens included Pm/Ax (33%), Ni/Ca (25%), Ni/Ax (20%), Av/Ax (11%), Ni/Ip/Ca (8%), Ni/Su (2%), and Ni/Ln (1%). ORR and mPFS stratified by line of tx and prior tx are shown in the table. Of 52 pts who received ICI/TKI tx as salvage (after 1L), 52% had a grade 3 or higher (≥G3) adverse event (AE), of which the most common were anorexia (13.5%), diarrhea and hypertension (11.5% each), and fatigue (9.6%). 65% of pts on salvage ICI/TKI tx stopped tx for progression/death, while 16% stopped tx for ≥G3 AE. ≥G3 AE rates by line of tx were 62.5% (2L), 50% (3L), and 45% (≥4L). Conclusions: ICI/TKI combination therapy is effective and safe beyond the 1L setting. Prior tx history appears to impact efficacy but has less of an effect on safety/tolerability. These observations will need to be confirmed in prospective studies.[Table: see text]

Background: Circulating tumor cells (CTCs) hold huge potential for both clinical applications and basic research into the management of cancer, but the relationship between CTC count and cervical cancer prognosis remains unclear. Therefore, research on this topic is urgently required. Objective: This study investigated whether CTCs were detectable in patients with cervical cancer and whether CTC count was an indicator of prognosis. Methods: We enrolled 107 patients with pathologically confirmed cervical cancer. CTCs were detected after radiotherapy or concurrent cisplatin-containing chemotherapy in all patients. We evaluated all medical records and imaging data as well as follow-up information to calculate progression-free survival (PFS). PFS was defined as the time until first diagnosis of tumor progression or death. We also analyzed the relationship between CTC count and patient age, disease stage, histological differentiation, tumor size, and pathological type. Results: CTCs were identified in 86 of 107 patients (80%), and the CTC count ranged from 0 to 27 cells in 3.2 mL blood. The median progression-free survival (PFS) was 43.1 months. Patients in which CTCs were detected had a significantly shorter PFS than CTC-negative patients (P = 0.018). Multivariate analysis indicated that CTC count was an independent negative prognostic factor for survival. However, no correlation was observed between CTC count and patient age, disease stage, histological differentiation, tumor size, and pathological type. Conclusion: CTC count is an independent negative prognostic factor for cervical cancer.

Cabozantinib is a multi-tyrosine kinase inhibitor used for the treatment of various solid-organ tumours. It was recently approved as a first- and second-line therapeutic for the management of advanced/metastatic renal cell carcinoma based on the results of two randomised controlled trials. The phase III METEOR trial compared cabozantinib against everolimus as a second- or greater line therapy and found benefits in progression-free and overall survival, and the phase II CABOSUN trial compared cabozantinib against sunitinib as a first-line therapeutic and found benefits in terms of progression-free survival. This review briefly summarises how cabozantinib fits into current treatment paradigms for the management of advanced renal cell carcinoma.

59 Background: In mCSPC, baseline CTC counts have been shown to correlate with PSA responses and progression free survival (PFS) in small studies in the context of androgen deprivation therapy (ADT) without modern intensification with docetaxel or novel hormonal therapy. Similar correlation of CTC count with PSA responses and PFS was recently reported from an ongoing phase 3 trial in mCSPC setting (SWOG1216) without reporting the association in the context of ADT intensification. Furthermore, none of these studies correlated CTCs with overall survival (OS). Herein we evaluated whether CTCs were associated with outcomes including OS in a real world mCPSC population treated with intensified as well as non-intensified ADT. Methods: Eligibility criteria: new mCSPC receiving ADT with or without intensification and enumeration of baseline CTCs by FDA cleared Cell Search CTC assay. The relationship between CTC counts (categorized as: 0, 1-4, and ≥5/7.5 ml) and both PFS and OS was assessed in the context of Cox proportional hazards models, both unadjusted and adjusted for age, Gleason, PSA at ADT initiation, de novo vs. non-de novo status, and ADT intensification vs. non-intensification therapy. Results: Overall 99 pts were identified. Baseline characteristics are summarized in Table. In unadjusted analyses, CTC counts of ≥5 as compared to 0 were strongly associated with inferior PFS (hazard ratio [HR] 3.38, 95% CI 1.85-6.18; p < 0.001) and OS (HR 4.44 95% CI 1.63-12.10; p = 0.004). In multivariate analyses, CTC counts of ≥5 as compared to 0 continued to be associated with inferior PFS (HR 5.49, 95% CI 2.64-11.43; p < 0.001) and OS (HR 4.00, 95% CI 1.31-12.23; p = 0.015). Within the ADT intensification subgroup also, high CTC counts were associated with poor PFS and OS. For PFS, the univariate HR for CTC ≥5 vs. 0 was 4.87 (95% CI 1.66-14.30; p = 0.004) and multivariate HR for CTC ≥5 vs. 0 was 7.43 (95% CI 1.92-28.82; p = 0.004). For OS, the univariate HR for CTC ≥5 vs. 0 was 15.88 (95% CI 1.93-130.58; p = 0.010) and multivariate HR for CTC ≥5 vs. 0 was 24.86 (95% CI 2.03-304.45; p = 0.012). Conclusions: To best of our knowledge this is the first study to show that high baseline CTC counts are strongly associated with inferior PFS as well as OS in pts with newly diagnosed mCSPC, even in those who received intensified ADT therapy. Identifying these pts at highest risk of progression and death can help with counselling and prognostication in clinics as well as design and enrollment in future clinical trials. [Table: see text]
