PurposeCigarette smoking induces CYP1A1/1A2 and is hypothesized to alter erlotinib pharmacokinetics. This study aimed to determine the maximum tolerated dose (MTD) of erlotinib in advanced non–small-cell lung cancer (NSCLC) patients who smoke and compare the pharmacokinetics of erlotinib at the MTD in current smokers with 150 mg.Patients and MethodsCohorts of NSCLC patients currently smoking ≥ 10 cigarettes per day for ≥ 1 year received escalating doses of erlotinib for 14 days until dose-limiting toxicity (DLT). A separate cohort of patients was then randomly assigned to erlotinib at either MTD or 150 mg daily with pharmacokinetics assessed at day 14. Erlotinib was continued until progression or intolerable toxicity.ResultsFour dose levels were evaluated in 22 patients: 200, 250, 300, and 350 mg. DLT was observed in one of six patients at 300 mg (rash) and two of five patients at 350 mg (acneiform dermatitis and fatigue/decreased Eastern Cooperative Oncology Group performance status). Thirty-five patients were randomly assigned to 150 mg or 300 mg. Common adverse events (all grades) were: skin toxicity (150 mg, 29%; 300 mg, 67%), diarrhea (150 mg, 18%; 300 mg, 50%), and fatigue (150 mg, 12%; 300 mg, 17%). Erlotinib exposure was dose-proportional within dose range tested. Median steady-state trough erlotinib plasma concentrations were 0.375 and 1.22 μg/mL for 150 mg and 300 mg, respectively.ConclusionThe MTD of erlotinib in NSCLC patients who smoke was 300 mg. Steady-state trough plasma concentrations and incidence of rash and diarrhea in smokers at 300 mg were similar to those in former or never smokers receiving 150 mg in previous studies. The potential benefit of higher erlotinib doses in current smokers warrants further evaluation.

691 Background: The primary objective was to assess the effect of concomitant RAM on the PK of IRI and its metabolite SN-38 when coadministered with FA and 5-FU. Methods: Key eligibility criteria included pts aged ≥18 years with metastatic or locally advanced malignant solid tumors resistant to standard therapy or for which no standard therapy was available, and an Eastern Cooperative Oncology Group performance status of 0 to 2. Pts received intravenous infusions of FOLFIRI and RAM 8 mg/kg on day 1 of a 2-week cycle. FOLFIRI was administered alone in cycle 1; RAM was administered followed by FOLFIRI in all subsequent cycles. Blood for PK was collected at regular intervals after infusions in cycles 1 and 2 to determine IRI and SN-38 plasma concentrations. Pts who completed the first 2 cycles of study treatment were included in the drug-drug interaction (DDI) population. All pts who received at least 1 dose of RAM or FOLFIRI were included in the safety population. Results: The safety population comprised 29 pts, and the DDI population included 25 of these 29 pts. The dose-normalized area under the concentration versus time curve from zero to infinity [AUC(0-∞)] and the maximum observed drug concentration (Cmax) of IRI and SN-38 were comparable between cycle 1 (FOLFIRI alone) and cycle 2 (RAM+FOLFIRI). The ratios of geometric least-squares (LS) means for IRI were 0.93 (90% CI; 0.83, 1.05) for AUC(0-∞) and 1.04 (90% CI; 0.97, 1.12) for Cmax. The ratios of geometric LS means for SN-38 were 0.95 (90% CI; 0.88, 1.04) for AUC(0-∞) and 0.97 (90% CI; 0.85, 1.12) for Cmax. The most prevalent treatment-emergent adverse events (TEAEs) were fatigue/asthenia (n=19, 65.5%), diarrhea (n=16, 55.2%), neutropenia (n=15, 51.7%), nausea (n=14, 48.3%), and decreased appetite and anemia (n=13 each, 44.8%). Grade ≥3 TEAEs were rare, except for neutropenia in 7 (24.1%) pts. Conclusions: The PKs of IRI and its metabolite, SN-38, were not affected when coadministered with RAM. RAM with FOLFIRI was well-tolerated in this study without new safety concerns. Clinical trial information: NCT01634555.

AbstractThis study aims to evaluate the influence of myosteatosis on survival of patients after radical cystectomy (RC) for bladder cancer. We retrospectively identified 230 patients who underwent RC for bladder cancer at our three institutions between 2009 and 2018. Digitized free-hand outlines of the left and right psoas muscles were made on axial non-contrast computed tomography images at level L3. To assess myosteatosis, average total psoas density (ATPD) in Hounsfield Units (HU) was also calculated as an average of bilateral psoas muscle density. We compared cancer-specific survival (CSS) between high ATPD and low ATPD groups and performed cox regression hazard analyses to identify the predictors of CSS. Median ATPD was 44 HU (quartile: 39–47 Hounsfield Units). Two-year CSS rate in overall patients was 76.6%. Patients with low ATPD (< 44 HU) had significantly lower CSS rate (P = 0.01) than patients with high ATPD (≥ 44 HU). According to multivariate analysis, significant independent predictors of poor CSS were: Eastern Cooperative Oncology Group performance status ≥ 1 (P = 0.03), decreasing ATPD (P = 0.03), non-urothelial carcinoma (P = 0.01), pT ≥ 3 (P < 0.01), and pN positive (P < 0.01). In conclusion, myosteatosis (low ATPD) could be a novel predictor of prognosis after RC for bladder cancer.

Eligibility Criteria

Immunotherapy based on anti PD-1/PD-L1 inhibitors is the new standard of advanced non-small cell lung cancers. Pembrolizumab, nivolumab and atezolizumab are used in clinical practice. The strict eligibility criteria of clinical trials do not allow researchers to fully represent treatment effects in the patients that will ultimately use these drugs. We performed a systematic review and a meta-analysis to evaluate the effectiveness and safety of these drugs, and more generally of ICIs, as second-line therapy in NSCLC patients in real world practice. MEDLINE, PubMed, Scopus and Web of Science were searched to include original studies published between January 2015 and April 2020. A total of 32 studies was included in the meta-analysis. The overall radiological response rate (ORR), disease control rate (DCR), median progression-free survival (PFS) and overall survival (OS) were 21%, 52%, 3.35 months and 9.98 months, respectively. The results did not change when analysis was adjusted for Eastern Cooperative Oncology Group performance status (ECOG PS) and age. A unitary increase in the percent of patients with liver and CNS metastases reduced the occurrence of DCR by 7% (p < 0.001) and the median PFS by 2% (p = 0.010), respectively. The meta-analysis showed that the efficacy and safety of immunotherapy in everyday practice is comparable to that in clinical trials.

Abstract Background Tracheobronchial adenoid cystic carcinoma (TACC) is a rare tumour. About one-third of patients miss their chance of surgery or complete resection as it is mostly detected in the advanced stage; hence, photon radiotherapy (RT) is used. However, the outcomes of photon RT remain unsatisfactory. Carbon ion radiotherapy (CIRT) is thought to improve the therapeutic gain ratio; however, the outcomes of CIRT in TACC are unclear. Therefore, we aimed to assess the effects and toxicities of CIRT in patients with TACC. Methods The inclusion criteria were as follows: 1) age 18–80 years; 2) Eastern Cooperative Oncology Group Performance Status 0–2; 3) histologically confirmed TACC; 4) stage III–IV disease; 5) visible primary tumour; and 6) no previous RT history. The planned prescription doses of CIRT were 66–72.6 GyE/22–23 fractions. The rates of overall survival (OS), local control (LC), and progression-free survival (PFS) were calculated using the Kaplan-Meier method. Treatment-induced toxicities and tumour response were scored according to the Common Terminology Criteria for Adverse Events and Response Evaluation Criteria in Solid Tumors, respectively. Results Eighteen patients with a median age of 48 (range 30–73) years were enrolled. The median follow-up time was 20.7 (range 5.8–44.1) months. The overall response rate was 88.2%. Five patients developed lung metastasis after 12.2–41.0 months and one of them experienced local recurrence at 31.9 months after CIRT. The rates of 2-year OS, LC, and PFS were 100, 100, and 61.4%, respectively. Except for one patient who experienced grade 4 tracheal stenosis, which was relieved after stent implantation, no other ≥3 grade toxicities were observed. Conclusions CIRT might be safe and effective in the management of TACC based on a short observation period. Further studies with more cases and longer observation are warranted.

PURPOSE: To compare a short intensified regimen followed by sequential consolidation therapy (doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone [ACVBP]) to the standard regimen of methotrexate, bleomycin, cyclophosphamide, and etoposide (m-BACOD) in patients with low-risk aggressive lymphoma. PATIENTS AND METHODS: A total of 752 patients with intermediate- or high-grade lymphoma and no adverse prognostic factors (Eastern Cooperative Oncology Group performance status of 2 to 4, ≥ two extranodal sites of disease, tumor burden ≥ 10 cm in largest dimension, bone marrow or CNS involvement, Burkitt’s or lymphoblastic subtypes) were registered. Of 673 eligible patients, 332 received ACVBP and 341 received m-BACOD. RESULTS: The complete remission rate was identical (86%) in the two groups. With a median follow-up duration of 7 years, the 5-year failure-free survival (FFS) rate was 65% in the ACVBP group and 61% in the m-BACOD group (P = .16). The 5-year overall survival rate was 75% in the ACVBP group and 73% in the m-BACOD group (P = .47). ACVBP was responsible for more severe and life-threatening infections (P < .01), but m-BACOD caused more pulmonary toxicity (P < .001). The number of treatment-related deaths did not differ between the two regimens. A multivariate analysis indicated that ACVBP was associated with a longer FFS in patients with two or three risk factors of the International Prognostic Index. CONCLUSION: In this population of patients with low-risk aggressive lymphoma, toxicities of the regimens are different, but the rates of response and survival are identical. The survival advantage of ACVBP over standard regimen in patients with advanced disease is suggested by this analysis but remains to be assessed in prospective studies specifically designed for this purpose.

Purpose The study objective was to determine the proportion of patients with hepatocellular carcinoma (HCC) treated with the combination of bevacizumab (B) and erlotinib (E) who were alive and progression free at 16 weeks (16-week progression-free survival [PFS16]) of continuous therapy. Secondary objectives included response rate, median PFS, survival, and toxicity. Patients and Methods Patients who had advanced HCC that was not amenable to surgical or regional therapies, up to one prior systemic treatment; Childs-Pugh score A or B liver function; Eastern Cooperative Oncology Group performance status 0, 1, or 2 received B 10 mg/kg every 14 days and E 150 mg orally daily, continuously, for 28-day cycles. Tumor response was evaluated every 2 cycles by using Response Evaluation Criteria in Solid Tumors Group criteria. A total of 40 patients were treated. Results The primary end point of PFS16 was 62.5%. Ten patients achieved a partial response for a confirmed overall response rate (intent-to-treat) of 25%. The median PFSevent was 39 weeks (95% CI, 26 to 45 weeks; 9.0 months), and the median overall survival was 68 weeks (95% CI, 48 to 78 weeks; 15.65 months). Grades 3 to 4 drug-related toxicity included fatigue (n = 8; 20%), hypertension (n = 6; 15%), diarrhea (n = 4; 10%) elevated transaminases (n = 4; 10%), gastrointestinal hemorrhage (n = 5; 12.5%), wound infection (n = 2; 5%) thrombocytopenia (n = 1; 2.5%), and proteinuria, hyperbilirubinemia, back pain, hyperkalemia, and anorexia (n = 1 each). Conclusion The combination of B + E in patients who had advanced HCC showed significant, clinically meaningful antitumor activity. B + E warrant additional evaluation in randomized controlled trials.

Background/Aim: Individual components of the metabolic syndrome (MS) such as obesity or diabetes mellitus impair the prognosis of patients with hepatocellular carcinoma (HCC) following curative treatment approaches or transarterial therapies. The aim of this retrospective study was to assess the impact of these factors on the overall survival (OS) of patients with advanced HCC treated with sorafenib. Methods: Univariate and multivariate analyses were performed to assess the impact of individual components of the MS on the OS of 152 consecutive patients with advanced HCC treated with sorafenib. Results: The presence of overweight/obesity, type 2 diabetes mellitus, hypertension, dyslipidemia, and of the MS itself did not impair the median OS. Multivariate analysis showed that Eastern Cooperative Oncology Group Performance Status ≥1 (hazards ratio [HR] 2.03), presence of macrovascular invasion (HR 1.71), Child-Pugh score B/C (HR 2.19), tumor grading G3 (HR 2.17), no prior HCC treatment (HR 2.34), and the presence of 2 or more out of 5 individual components of the MS (HR 0.65) were independent prognostic factors regarding the median OS. Conclusions: Our investigations do not confirm a negative prognostic role of individual components of the MS or the MS itself for patients with advanced HCC treated with sorafenib.

PURPOSE: To appraise the performance of Comprehensive Geriatric Assessment (CGA) in elderly cancer patients (≥ 65 years) and to evaluate whether it could add further information with respect to the Eastern Cooperative Oncology Group performance status (PS). PATIENTS AND METHODS: We studied 363 elderly cancer patients (195 males, 168 females; median age, 72 years) with solid (n = 271) or hematologic (n = 92) tumors. In addition to PS, their physical function was assessed by means of the activity of daily living (ADL) and instrumental activities of daily living (IADL) scales. Comorbidities were categorized according to Satariano’s index. The association between PS, comorbidity, and the items of the CGA was assessed by means of logistic regression analysis. RESULTS: These 363 elderly cancer patients had a good functional and mental status: 74% had a good PS (ie, lower than 2), 86% were ADL-independent, and 52% were IADL-independent. Forty-one percent of patients had one or more comorbid conditions. Of the patients with a good PS, 13.0% had two or more comorbidities; 9.3% and 37.7% had ADL or IADL limitations, respectively. By multivariate analysis, elderly cancer patients who were ADL-dependent or IADL-dependent had a nearly two-fold higher probability of having an elevated Satariano’s index than independent patients. A strong association emerged between PS and CGA, with a nearly five-fold increased probability of having a poor PS (ie, ≥ 2) recorded in patients dependent for ADL or IADL. CONCLUSION: The CGA adds substantial information on the functional assessment of elderly cancer patients, including patients with a good PS. The role of PS as unique marker of functional status needs to be reappraised among elderly cancer patients.

5583 Background: Endometrial cancer is one of the most common gynecologic malignancies in the world. however, the effects of systemic chemotherapy are limited. The combination of targeted therapy with immunotherapy is a new research field in the treatment of malignant tumors. Anlotinib is a novel tyrosine kinase inhibitor with highly selective inhibition effects on multi-targets, especially on vascular endothelial growth factor receptor, Platelet-derived growth factor receptor and Fibroblast growth factor receptor. Sintilimab is a highly selective, fully humanized, monoclonal antibody, which blocks the interaction between Programmed death 1 and its ligands. This research aimed to evaluate the efficacy and safety of the combination of anotinib and sintilimab in patients with recurrent advanced endometrial cancer. Methods: Patients who received at least one platinum-based systemic chemotherapy, had an Eastern Cooperative Oncology Group performance status of 0 or 1 were considered eligible for enrollment. Sintilimab was administered intravenously (200mg，q3w); anlotinib was taken orally (12mg qd, d1-14, 21 days per cycle). The treatment was continued until disease progression, death or intolerant toxicity. The primary endpoint was objective response rate (ORR) and the secondary endpoints included duration of response, disease control rate (DCR), progression-free survival (PFS), overall survival and safety. Results: From November 2019 to to September 2020, 23 patients with a median age of 56 years (range: 37-70), FIGO stage IA (21.7%), IB (8.7%), II (4.4%), IIIA (13.1%)，IIIC (30.4%), IVB (21.7%) were enrolled. Among these participants, 22 patients were evaluable. The therapeutic evaluation showed the incidence of complete response, partial response, stable disease and progression disease was 13.6%, 63.7%, 13.6% and 9.1% respectively, yielding the ORR of 77.3% (95%CI: 58.3%-96.3%) and the DCR of 91.7% (95%CI: 79.8%-100%). ≥1 and ＜1 Combined Positive Score of PD-L1 expression were observed in 66.7% (14/21) and 33.3% (7/21) patients respectively, and the ORR was 92.9% (95%CI: 77.4%-100%) and 57.1% (95%CI: 18.4%-90.1%) in the two groups. The median time of the first response was 1.5 months (range, 0.7-12.8). The median PFS was not reached. Most of the occurring adverse events (AEs) were grade 1 or 2. Grade 3 AEs included ileus (4.3%), immune myocarditis (4.3%) immune peritonitis (4.3%), hand-foot syndrome (8.7%), neutropenia (4.3%), neutrophils decrease (4.3%), and hypertension (4.3%); Grade 4 AE was lymphocytosis (4.3%). Neither unexpected safety signals nor treatment-related death occurred. Conclusions: Anlotinib plus sintilimab showed a promising antitumor activity with a favorable toxicity profile for patients with recurrent advanced endometrial cancer. We will report more data in the future. Clinical trial information: NCT04157491.

Treatment Patterns

414 Background: There are a lack of published real-world data on treatment patterns for patients with locally advanced or metastatic urothelial carcinoma (la/mUC) previously treated with programmed death 1/ligand 1 inhibitor (PD-1/L1i) therapy. The objective of this study was to characterize the clinical characteristics and treatments among patients with la/mUC following discontinuation of first-line (1L) or second-line (2L) PD-1/L1i therapy. Methods: We performed a retrospective chart review at 26 geographically diverse clinical sites in the US. Patients aged ≥18 years with histologically or cytologically confirmed urothelial carcinoma and radiographic evidence of metastatic or locally advanced disease were identified. Included patients had initiated and subsequently discontinued PD-1/L1i therapy in the 1L or 2L setting for la/mUC between May 15, 2016-July 31, 2018. All patients had follow-up through October 31, 2019. Data were summarized using descriptive statistics. Results: Among the 300 patients included in the chart review, 198 (66%) received PD-1/L1i therapy as 1L and 102 (34%) as 2L therapy. Mean (SD) age at la/mUC diagnosis was 69.4 (8.7) years, and a majority of patients were male (66.0%) and White (74.7%). Consistent with age, most patients (82.7%) had comorbidities at la/mUC diagnosis; 39.7% hypertension, 23.7% coronary artery disease, 17.7% pulmonary disease, and 9.3% renal disease. At initiation of therapy, a higher proportion of patients who received 1L PD-1/L1i therapy had an Eastern Cooperative Oncology Group performance status of 2 or more than patients who received 2L PD-1/L1i therapy (36.8% vs 22.5%, respectively). Following discontinuation of PD-1/L1i therapy, 34% (n = 68) received subsequent therapy in 2L and 29% (n = 30) in third-line (3L). The most common subsequent therapies in 2L were gemcitabine monotherapy (24%), gemcitabine plus cisplatin or carboplatin (22%), PD-1/L1i therapy (22%), and taxane monotherapy (19%). The most common subsequent therapies received in 3L were taxane monotherapy (50%), pemetrexed (17%), and PD-1/L1i therapy (16%). Overall, switching from one PD-1/L1i therapy to another distinct PD-1/L1i therapy occurred in approximately 20% of patients, with “better efficacy/survival” noted by treatment teams as the most common reason for switching therapy among this subgroup. Conclusions: In this real-world case series, only a minority of patients with la/mUC who discontinued PD-1/L1i therapy received subsequent therapy. Among those that did, no clear standard of care was observed and approximately one-fifth of patients were treated with a second PD-1/L1i therapy after the first failed to control disease. Collectively, the data highlight significant unmet need for patients with la/mUC who discontinue PD-1/L1i therapy.
