Abstract Background MRI may provide insights into longitudinal responses in the diffusivity and vascular function of the irradiated normal-appearing brain following stereotactic radiosurgery (SRS) of brain metastases. Methods Forty patients with brain metastases from non-small cell lung cancer (N = 26) and malignant melanoma (N = 14) received SRS (15–25 Gy). Longitudinal MRI was performed pre-SRS and at 3, 6, 9, 12, and 18 months post-SRS. Measures of tissue diffusivity and vascularity were assessed by diffusion-weighted and perfusion MRI, respectively. All maps were normalized to white matter receiving less than 1 Gy. Longitudinal responses were assessed in normal-appearing brain, excluding tumor and edema, in the LowDose (1–10 Gy) and HighDose (>10 Gy) regions. The Eastern Cooperative Oncology Group (ECOG) performance status was recorded pre-SRS. Results Following SRS, the diffusivity in the LowDose region increased continuously for 1 year (105.1% ± 6.2%; P < .001), before reversing toward pre-SRS levels at 18 months. Transient reductions in microvascular cerebral blood volume (P < .05), blood flow (P < .05), and vessel densities (P < .05) were observed in LowDose at 6–9 months post-SRS. Correspondingly, vessel calibers in LowDose transiently increased at 3–9 months (P < .01). The responses in HighDose displayed similar trends as in LowDose, but with larger interpatient variations. Vascular responses followed pre-SRS ECOG status. Conclusions Our results imply that even low doses of radiation to normal-appearing brain following cerebral SRS induce increased diffusivity and reduced vascular function for up until 18 months. In particular, the vascular responses indicate the reduced ability of the normal-appearing brain tissue to form new capillaries. Assessing the potential long-term neurologic effects of SRS on the normal-appearing brain is warranted.

e21667 Background: Previous studies suggested that the efficacy of osimertinib was better in patients with epidermal growth factor receptor ( EGFR) exon 19 deletion (ex19del) than exon 21 Leu858Arg (L858R). However, the differential clinical outcomes of osimertinib in previous tyrosine kinase inhibitors (TKIs) treated non-small-cell lung cancer (NSCLC) patients with brain metastases (BrMs) according to the two different common EGFR genotypes remains undetermined. Methods: We retrospectively collected EGFR mutant (ex19del and L858R) NSCLC patients with BrMs and received osimertinib treatment between Jan 2016 and Feb 2019 in our hospital. Other eligible standards including Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-2, osimertinib 80mg monotherapy and neurologic symptoms existing was permitted to enroll in our study. Results: 78 patients with EGFR mutant NSCLC and BrMs were included in the study. EGFR mutation types were ex19del in 55% of patients (43/78) and L858R in 45% of patients (35/78). All of patients received at least one prior EGFR-TKI therapy, among which 46% (36/78) had gefitinib, 49% (38/78) had erlotinib, 19% (15/78) had icotinib. T790M status at osimertinib initiation was positive in 81% of patients (63/78), negative in 4% (3/78), unknown in 15% (12/78). The systemic objective response rate (ORR) was 46%. There was no apparent difference in systemic ORR (49% vs 43%, P = 0.598) between ex19del group and L858R group. The median progression free survival (PFS) and overall survival (OS) were 7.0 (range 4.7-9.3) and 18.8 (range 14.0-23.5) months for all patients. The median PFS in the ex19del and L858R subgroups was 9.1 (range 6.0-12.1) months and 5.3 (range 3.4-7.2) months, respectively ( P = 0.031). The median OS in the ex19del and L858R subgroups was 26.0 (range 13.7-38.3) months and 13.9 (range 7.7-20.2) months, respectively ( P = 0.033). Multivariate analysis identified L858R and ECOG PS 2 as poor independent predictors to the PFS and OS. Conclusions: The efficacy of osimertinib was associated with EGFR genotypes in pre-TKI treated NSCLC patients with BrMs, and L858R maybe an independent bad factor for long-term outcomes of osimertinib.

<b><i>Introduction:</i></b> Intraductal papillary mucinous neoplasms (IPMNs) represent the most common precancerous cystic lesions of the pancreas. The aim of our study was to investigate if resection for non-invasive IPMNs alters quality of life (QoL) in a long-term follow-up. <b><i>Methods:</i></b> Patients (<i>n</i> = 50) included in the analysis were diagnosed and resected from 2010 to 2016. QoL was assessed at a median of 5.5 years after resection. At that point in time, the current QoL as well as the QoL before resection was evaluated retrospectively. The standardised European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Pancreatic Cancer (EORTC QLQ – PAN26) was applied for the QoL assessment. <b><i>Results:</i></b> After a median of 66 months postoperatively, the total QoL score significantly worsened (92.13 vs. 88.04, <i>p</i> = 0.020, maximum achievable score = 100) for patients (median age at surgery 68.0 years), mostly due to digestive symptoms. During the same follow-up period, median Eastern Cooperative Oncology Group (ECOG) performance status did not worsen (<i>p</i> = 0.003). <b><i>Conclusions:</i></b> Long-term QoL statistically significantly worsened after pancreatic resection for IPMN. The extent of worsening, however, was small, and QoL still remained excellent. Therefore, resection in cases of IPMN is appropriate, if indicated carefully.

IntroductionBrain metastases (BM) are associated with dismal prognosis, and there is a dearth of effective systemic therapy. In this study, patients with BM from multiple solid tumors were identified from TriNetX databases, their clinicopathological features were evaluated, and the effects of immune checkpoint inhibitor (ICI) therapy were assessed.MethodsVariables, including median overall survival (OS), Eastern Cooperative Oncology Group (ECOG) performance status, primary diagnosis, and date of diagnosis, were retrieved from TriNetX, a real-world database. Kaplan-Meier plots and log-rank tests were applied to assess significance of differences in survival. Hazard ratio (HR) and 95% confidence interval (CI) values were calculated. All patient data were deidentified.ResultsA total of 227,255 patients with BM were identified in the TriNetX database; median OS was 12.3 months from initial cancer diagnosis and 7.1 months from development of BM. OS of BM from nonsmall-cell lung cancer (NSCLC), triple-negative breast cancer (TNBC), melanoma, and renal cell carcinoma (RCC) were 8.7, 14.7, 17.8, and 15.6 months, respectively. After matching patient baseline characteristics, OS of cohorts with or without exposure to ICIs was evaluated. For all types of cancer, median OS durations for the ICI and no-ICI cohorts were 14.0 and 7.9 months, respectively (HR: 0.88; 95% CI: 0.85–0.91). More specifically, OS was remarkably prolonged in patients with NSCLC (14.4 vs. 8.2 months; HR: 0.86; 95% CI: 0.82–0.90), TNBC (23.9 vs. 11.6 months; HR: 0.87; 95% CI: 0.82–0.92), and melanoma (27.6 vs. 16.8 months; HR: 0.80; 95% CI: 0.73–0.88) if patients had exposure to ICIs. In contrast, there was no significant difference in OS of patients with RCC treated with and without ICIs (16.7 vs. 14.0 months; HR: 0.96; 95% CI: 0.86–1.10).ConclusionsOverall, BM indicates poor patient outcome. Treatment with ICIs improves survival of patients with NSCLC, TNBC, and melanoma and BM; however, no significant improvement was observed in RCC. Investigations to identify prognostic features, oncogenomic profiles, and predictive biomarkers are warranted.

Abstract BackgroundIt is widely known that platinum-based doublet chemotherapy (PBC) only can be applied to first-line patients with non-small cell lung cancer (NSCLC) with good performance for 4-6 cycles. However, in this case report the patient has been treated with PBC for 30 cycles and more than three years. Case presentationA 63-year-old Chinese man was diagnosed with stage IVa lung adenocarcinoma, with Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0. This patient did not respond to pemetrexed alone, but respond to pemetrexed and carboplatin, and once the chemotherapy was interrupted for more than two months, the disease would progressed. Moreover, there was little adverse reactions (AE), so we have treated him with PBC for 30 cycles and the progression-free survival (PFS) will be more than three years.ConclusionsThis is the first time to report PBC as maintenance therapy in patients with NSCLC. We hope that oncologists will notice that some diseases are very aggressive, and maintenance therapy are very important to some patients and may help to get longer overall survival time.

9016 Background: 1L NIVO + IPI was shown to provide durable long-term overall survival (OS) benefit vs chemo regardless of tumor programmed death ligand 1 (PD-L1) expression in patients (pts) with advanced NSCLC in CheckMate 227 Part 1 (NCT02477826); 3-year OS rates were 33% vs 22% in pts with PD-L1 ≥ 1% (HR, 0.79 [95% CI, 0.67–0.93]) and 34% vs 15% in pts with PD-L1 < 1% (HR, 0.64 [95% CI, 0.51–0.81]). Here we report updated results from the study with 4 years’ minimum follow-up. Methods: Adults with previously untreated stage IV / recurrent NSCLC, no known EGFR/ ALK alterations , and ECOG performance status ≤ 1 were enrolled; pts were stratified by squamous (SQ) and non-squamous (NSQ) histology. Pts with PD-L1 ≥ 1% (n = 1189) were randomized 1:1:1 to receive NIVO (3 mg/kg Q2W) + IPI (1 mg/kg Q6W), NIVO alone (240 mg Q2W), or chemo. Pts with PD-L1 < 1% (n = 550) were randomized 1:1:1 to receive NIVO + IPI, NIVO (360 mg Q3W) + chemo, or chemo. OS with NIVO + IPI vs chemo in pts with PD-L1 ≥ 1% was the primary endpoint. Results: With minimum follow-up of 49.4 months (database lock, Feb 18, 2021), pts were at least 2 years beyond the protocol-specified end of immunotherapy treatment. Pts with PD-L1 ≥ 1% continued to show durable benefit with NIVO + IPI vs chemo (HR, 0.76 [95% CI, 0.65–0.90]); 4-year OS rates were 29% (NIVO + IPI), 21% (NIVO), and 18% (chemo). At 4 years, 14% (NIVO + IPI), 10% (NIVO), and 4% (chemo) remained progression free. Among responders, 34%, 30%, and 7% remained in response, respectively. In an exploratory analysis in pts with PD-L1 ≥ 50%, 4-year OS rates were 37% (NIVO + IPI), 26% (NIVO), and 20% (chemo). In pts with PD-L1 < 1%, OS HR for NIVO + IPI vs chemo was 0.64 (95% CI, 0.51–0.81); 4-year OS rates were 24% (NIVO + IPI), 13% (NIVO + chemo) and 10% (chemo). At 4 years, 12% (NIVO + IPI), 7% (NIVO + chemo), and 0% (chemo) remained progression free. Among responders, 31%, 13%, and 0% remained in response, respectively. Among pts who progressed on NIVO + IPI vs chemo, 7% vs 40% (PD-L1 ≥ 1%), and 9% vs 33% (PD-L1 < 1%), received subsequent immunotherapy. Benefit with NIVO + IPI vs chemo was observed for both SQ and NSQ histology (Table). With long-term follow-up, no new safety signals were identified. Conclusions: With 4 years’ minimum follow-up, 1L NIVO + IPI continued to provide durable, long-term OS benefit vs chemo in pts with advanced NSCLC regardless of PD-L1 expression or histology.

Abstract Background: Measuring functional status in palliative care may help clinicians to assess a patient’s prognosis, recommend adequate therapy, avoid futile or aggressive medical care, consider hospice referral, and evaluate provided rehabilitation outcomes. An optimized, widely used, and validated tool is preferable. The Palliative Performance Scale Version 2 (PPSv2) is currently one of the most commonly used performance scales in palliative settings. The aim of this study is the translation and validation process of a Polish translation of this tool (PPSv2-Polish). Methods: Two hundred patients consecutively admitted to a free-standing hospice were evaluated twice during 2 consecutive days for test-retest reliability. In the first evaluation, two different care providers independently evaluated the same patient to establish inter-rater reliability values. PPS-Polish was compared with the Karnofsky Performance Score (KPS), Eastern Cooperative Oncology Group (ECOG) Performance Status (ECOG PS), and Barthel Activities of Daily Living (ADL) Index to determine its construct validity. Results: A high level of full agreement between test and retest was seen (63%), and a good intra-class correlation coefficient of 0.85 (P<0.0001) was achieved. Excellent agreement between raters was observed when using PPSv2-Polish (Cohen’s kappa 0.91; P<0.0001). Satisfactory correlations with the KPS and good correlations with ECOG PS and Barthel ADL were noticed. Persons who had shorter prognoses and were predominantly bedridden also had lower scores measured by the PPSv2-Polish, KPS and Barthel ADL. A strong correlation of 0.77 between PPSv2-Polish scores and survival time was noted (P<0.0001). Moderate survival correlations were seen between KPS, ECOG PS, and Barthel ADL of 0.41; -0.62; and 0.58, respectively (P<0.0001). Conclusion: PPSv2-Polish is a valid and reliable tool measuring performance status in a hospice population and can be used in daily clinical practice in palliative care and research.

Based on the reports of activity of interferons against metastatic melanomas, we conducted a phase II study of recombinant interferon alfa-2a (Roferon-A, Hoffmann-La Roche, Nutley, NJ) in 66 patients with disseminated melanoma. All patients had excellent Eastern Cooperative Oncology Group (ECOG) performance status (0 to 1), and no evidence of brain metastases. Thirty patients had previously received chemotherapy and the remainder were untreated. The first 35 patients were treated on a daily schedule starting with a Roferon-A dose of 3 X 10(6) U/d and escalating to a maximum of 36 X 10(6) U/d over a period of 12 days. Because of excessive toxicity, the second group of 31 patients were treated on a fixed dose of 18 X 10(6) U/d [corrected] three times weekly (TIW). Among the 62 evaluable patients, five achieved an objective response for a response rate of 8% (95% confidence limits, 3% to 18%). Four patients had minor regressions and eight patients had stability of disease. The responses were evenly distributed between the two dose schedules. The major toxicity of interferon consisted of a constitutional syndrome of anorexia, fever, weight loss, and fatigue, which required a dose reduction in 75% of the patients on the daily schedule. Our data revealed a modest level of activity, which was not influenced by prior treatment or by the dose or schedule of interferon. Because of substantial toxicity with the daily schedule, we recommend a dose of 18 X 10(6) U/d [corrected] if interferon is used in the treatment of patients with melanoma.

Breast Cancer (BC) is the leading cause of death in women, worldwide. The Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of BC can be studied using HRV measures. The main purpose of this chapter is to give an insight to clinicians via HRV measures with respect to age to make them understand the PS of patients. Data from 114 BC patients was segregated into two age groups, G1 (20 to 40 years) and G2 (41 to 75 years). The 5-minute electrocardiogram of the subjects was taken and HRV measures were extracted. One-way ANOVA with Posthoc Tukeys' HSD test was done. Triangular Index, Ratio of standard deviation of poincare plot perpendicular to the line of identity to the standard deviation along line of identity, Detrended Fluctuation Analysis descriptors, Approximate Entropy, Sample Entropy and Correlation Dimension significantly decreased from ECOG0 to 4 and from G1 to G2. The sympathetic activity increased with vagal withdrawal as age advanced.

Abstract Background Regorafenib is a multi-kinase inhibitor approved as third line treatment for metastatic GIST. Dose limiting toxicities are frequently seen and many patients require dose reductions. This study aimed to evaluate regorafenib toxicities and their management in a real-world GIST population. Methods Retrospective review of a prospectively maintained database identified 50 patients with GIST treated with regorafenib at our centre between March 2013 and September 2018. Results Median progression free survival (PFS) was 7.7 months [interquartile range (IQR) 2.8–14.4 months]. Median overall survival (OS) from start of regorafenib to death or last follow up was 15.7 months (IQR 9.2–28.4 months). Baseline median Eastern Cooperative Oncology Group (ECOG) performance status on starting regorafenib was 1. The main reason for discontinuing regorafenib was progressive disease (PD) (31/50 [62%]) rather than toxicity (10/50 [20%]). Grade 3–4 adverse events (AEs) were seen in 23/50 (46%) patients; palmar-plantar erythrodysesthesia (PPE) was most frequently seen (9/50 (18%)). Two patients died whilst on treatment with regorafenib from multi-organ failure secondary to sepsis (4%). Dose reductions were required in 19/50 patients (38%) and 8/50 (16%) patients started regorafenib at a lower dose band than the recommended dose (160 mg) due to comorbidities or concern over a higher individual risk of toxicity. Conclusion Although PD was the main reason for discontinuing treatment, toxicity management and dosing of regorafenib remains critical. Median duration of treatment was longer compared to previous studies suggesting a durable clinical benefit with regorafenib with rigorous toxicity management.

Trifluridine/tipiracil (FTD/TPI) significantly improves overall survival in patients with metastatic colorectal cancer (mCRC). The most common treatment-related event (grade ≥3) was hematological toxicity. We here report long-term disease-stabilizing FTD/TPI treatment of an mCRC patient (KRAS wild-type, ECOG performance status 1 at baseline and at the end of FTD/TPI therapy) with multifocal synchronous metastases and a longstanding history of extensive hematological events during previous treatments. Finally, this 62-year-old male patient was treated for 10 months with FTD/TPI by consecutive alteration of treatment parameters: (i) initial daily dose reduction to 80 mg (72% of the recommended dose), (ii) 20 days dose delay, (iii) a second and later third dose reduction to 70 mg and 60 mg (about 64% and 55%, respectively, of the recommended dose), and (iv) 30 µg per day of granulocyte colony-stimulating factor administration first for 3 days, and later for 5 days, for each treatment cycle.
