135 Background: Neoadjuvant chemotherapy (NAC) of 5-fluorouracil plus cisplatin infusion (FP) is standard therapy for stage IB/II/III (excluding T4) esophageal cancer from results of JCOG9907 and definitive chemoradiotherapy (dCRT) of FP is one of the curative options for resectable esophageal cancer with organ preservation results of JCOG9906 in Japan. However, the efficacy and feasibility of NAC FP and CRT for elderly patients (pts) are unclear. Methods: We examined stage IB/II/III (excluding T4) esophageal cancer pts aged 70 or over, who received NAC FP or dCRT at our institution between April 2008 and August 2015, retrospectively. Results: 16 pts received NAC FP at least 1 course, while 5 pts received dCRT because of intolerability for surgery, reject of surgery, and patient's wish. Median age was 73/75 (NAC FP/dCRT) and pts in NAC FP had more advanced stage cancer compared with pts in dCRT (p = 0.02). With respect to the toxicity, bone marrow depression developed in dCRT with more high frequency compared with NAC FP, but no pts had febrile neutropenia. Adverse effects of fatigue, nausea and appetite loss developed in both group frequently. 3 pts were not performed surgery because of decreased respiratory function, decreased PS and progression disease and 4 pts did not achieved 4 cycle of FP infusion because of leukopenia, decreased renal function, and gastrointestinal toxicity. 12 pts in NAC FP undergone R0 resection surgery and 4 pts had a complete remission. The 5-year progression free survival rate was 50% (95% CI: 12-86%) in dCRT and 50% (95% CI: 20-80%) in NAC FP (p = 0.69). The 5-year overall survival rate was 50% (95% CI: 12-86%) in dCRT and 67% (95% CI: 36-88%) in NAC FP (p = 0.83). Conclusions: NAC FP and dCRT for stage IB/II/III (excluding T4) esophageal cancer might be effective even in pts ≥ 70 years of age. The therapy of dCRT might be one of options for elderly inoperative patients.

296 Background: PETCAM was a randomized trial evaluating the effect of PET-CT compared to conventional imaging (control) on the surgical management of patients with resectable colorectal cancer liver metastases (CRLM). It concluded that PET-CT did not result in frequent change in surgical management (8·0%, 21/263) with only 2·7% (7/263) avoidance of liver resections. In this study we conducted a cost analysis of these two arms up to one year following randomization. Methods: Health care utilization was collected for all study participants. Unit costs for hospitalization, physician services, chemotherapy and outpatient radiological and endoscopic procedures were obtained from administrative databases. Cost analysis was undertaken from the perspective of a third-party payer (i.e., Ministry of Health). Mean cost with its 95% credible interval was estimated using a Bayesian approach. Results: The estimated mean cost per patient in the PET-CT arm was CAN $45,454 (min-max: 1,340-181,420) and in the control arm, CAN $40,859 (min-max: 279-293,558), with a net difference of CAN $4,327, 95% credible interval -2,207 to 10,614. The primary cost driver was cost of hospitalization for liver surgery (+ $2,997 CAN for the PET-CT arm), mainly due to a longer length of hospital stay for the PET-CT arm compared to control (median 7 days vs. 6 days, P= 0·034) and a higher rate of postoperative complications (52/255, 20% vs. 13/128, 10%, P = 0·014). Baseline characteristics were similar between groups, including a similar number of liver segments involved with cancer, number of segments resected and type of liver resection performed. Conclusions: PET-CT does not appear to provide a significant clinical benefit in the surgical management of patients with resectable CRLM and it is not cost saving compared to control.

6 Background: Patients (pts) with GC/GEC often present with A/M disease, which has a poor prognosis, with 1-year survival < 30%, and few treatment options. Nivolumab is a fully human anti-PD-1 IgG4 monoclonal antibody with a favorable safety profile and efficacy in melanoma, non–small-cell lung cancer, and renal cell carcinoma. The phase I/II, open-label CheckMate-032 study evaluated nivolumab ± ipilimumab in pts with solid tumors. Here, we report initial results for pts with GEC/GC receiving nivolumab monotherapy. Methods: Pts with A/M histologically confirmed GC/GEC, irrespective of PD-L1 status, were assigned to receive nivolumab alone (3 mg/kg IV Q2W) and treated until disease progression (PD) or intolerable toxicity. The primary endpoint was objective response rate (ORR); other endpoints included safety, progression-free survival, overall survival (OS), and biomarker status. Results: 59 pts were enrolled and treated with single-agent nivolumab. Median age was 60 y (range 29–80), and 83% of pts received ≥ 2 prior regimens. At database lock, 10 pts were on active treatment; 49 pts discontinued (PD, n = 40; unrelated adverse events, n = 4; treatment-related adverse events [TRAEs], n = 2; other, n = 3). Pts received a median of 4 doses (range 1–25). ORR was 12% (n = 7/58; 1 complete response, 6 partial responses); 12 pts (21%) had stable disease. Among responders, median duration of response was 7.1 mo (95% CI, 3.0–13.2). Median OS was 6.8 mo (95% CI, 3.3–12.4); 12-mo OS rate was 38% (95% CI, 23.2–52.7). 39% of tumor samples were PD-L1 positive ( ≥ 1% cutoff). ORRs in pts with PD-L1-positive and -negative tumors were 18% and 12%, respectively. TRAEs occurred in 66% of pts; most were Grade 1/2. Grade 3/4 TRAEs occurred in 14% of pts and included pneumonitis, fatigue, diarrhea, vomiting, hypothyroidism, and increased aspartate and alanine aminotransferase and alkaline phosphatase levels. No treatment-related deaths occurred. Conclusions: Nivolumab monotherapy was well tolerated and demonstrated encouraging antitumor activity in heavily pretreated pts with GC/GEC. Objective responses occurred in pts with PD-L1-positive and -negative tumors. Clinical trial information: NCT01928394.

770 Background: The use of selective internal radiation therapy (SIRT) with SIR-Spheres in chemotherapy-resistant colorectal cancer liver metastases (CRC-L) has been associated with favorable progression free survival (PFS) and overall survival (OS) when given alone or concurrently with chemotherapy. However, no prospective studies exist for concurrent SIRT and chemotherapy (SIRT-CT) vs. SIRT alone. We conducted a single institute retrospective trial to compare the effect of SIRT-CT to SIRT alone on liver PFS in patients with CRC-L. Methods: Patients (pts) with CRC-L treated with SIR-Spheres at City of Hope between 2009 and 2014 were identified. CRL-L patients treated with SIRT-CT or with SIRT were excluded if they received, following radioembolization, any chemotherapy/targeted regimen on which they did not previously progress. This strategy was adopted to minimize the impact of post-SIRT systemic therapy bias on SIRT-CT/SIRT liver PFS outcome. Pts characteristics included demographics, liver involvement pattern, and lines of prior chemotherapy. Liver PFS, response rate, and toxicities were compared between SIRT-CT and SIRT arms. Kaplan-Meier estimation was used for PFS analysis. Results: 48 CRC-L pts were treated with SIR-spheres; 27 satisfied the post-SIR-spheres systemic treatment criteria (14 SIRT-CT, 13 SIRT) and were included on this study. Pts characteristics included: age (median = 62; range 52-80), sex (18 males), primary site (colon: 23), hepatic disease burden (23 bilobar), 5-FU resistance/intolerance (25/2), and extrahepatic disease (22). Pts characteristics were similar between treatment arms, except for median prior therapies (SIRT-CT = 3, SIRT = 2). No SIRT-CT or SIRT associated ≥ grade 3 toxicities were noted. Disease control rates were 84% (2/13 PR; 9/13 SD) and 14% (2/14 SD on the SIRT-CT and SIRT arms, respectively (p = 0.001). Median PFS in the liver was 176 days in the SIRT-CT group vs. 91 days in the SIRT group (p = 0.0006). Conclusions: In patients with 5-FU refractory CRC-L, SIRT-CT is associated with an increased disease control rate and a prolonged DFS in comparison with SIRT alone.

Purpose This two-part, first-in-human study was initiated in patients with advanced solid tumors harboring genetic alterations in fibroblast growth factor receptors (FGFRs) to determine the maximum tolerated dose (MTD), the recommended phase II dose (RP2D), and the schedule, safety, pharmacokinetics, pharmacodynamics, and antitumor activity of oral BGJ398, a selective FGFR1-3 tyrosine kinase inhibitor. Patients and Methods Adult patients were treated with escalating dosages of BGJ398 5 to 150 mg once daily or 50 mg twice daily continuously in 28-day cycles. During expansion at the MTD, patients with FGFR1-amplified squamous cell non–small-cell lung cancer (sqNSCLC; arm 1) or other solid tumors with FGFR genetic alterations (mutations/amplifications/fusions) received BGJ398 daily on a continuous schedule (arm 2), or on a 3-weeks-on/1-week-off schedule (arm 3). Results Data in 132 patients from the escalation and expansion arms are reported (May 15, 2015, cutoff). The MTD, 125 mg daily, was determined on the basis of dose-limiting toxicities in four patients (100 mg, grade 3 aminotransferase elevations [n = 1]; 125 mg, hyperphosphatemia [n = 1]; 150 mg, grade 1 corneal toxicity [n = 1] and grade 3 aminotransferase elevations [n = 1]). Common adverse events in patients treated at the MTD (n = 57) included hyperphosphatemia (82.5%), constipation (50.9%), decreased appetite (45.6%), and stomatitis (45.6%). A similar safety profile was observed using the 3-weeks-on/1-week-off schedule (RP2D). However, adverse event–related dose adjustments/interruptions were less frequent with the 3-weeks-on/1-week-off (50.0%) versus the continuous (73.7%) schedule. Antitumor activity (seven partial responses [six confirmed]) was demonstrated with BGJ398 doses ≥ 100 mg in patients with FGFR1-amplified sqNSCLC and FGFR3-mutant bladder/urothelial cancer. Conclusion BGJ398 at the MTD/RP2D had a tolerable and manageable safety profile and showed antitumor activity in several tumor types, including FGFR1-amplified sqNSCLC and FGFR3-mutant bladder/urothelial cancers.

Purpose Trastuzumab and pertuzumab are human epidermal growth factor receptor 2 (HER2) –targeted monoclonal antibodies, and trastuzumab emtansine (T-DM1) is an antibody–drug conjugate that combines the properties of trastuzumab with the cytotoxic activity of DM1. T-DM1 demonstrated encouraging efficacy and safety in a phase II study of patients with previously untreated HER2-positive metastatic breast cancer. Combination T-DM1 and pertuzumab showed synergistic activity in cell culture models and had an acceptable safety profile in a phase Ib and II study. Methods In the MARIANNE study, 1,095 patients with centrally assessed, HER2-positive, advanced breast cancer and no prior therapy for advanced disease were randomly assigned 1:1:1 to control (trastuzumab plus taxane), T-DM1 plus placebo, hereafter T-DM1, or T-DM1 plus pertuzumab at standard doses. Primary end point was progression-free survival (PFS), as assessed by independent review. Results T-DM1 and T-DM1 plus pertuzumab showed noninferior PFS compared with trastuzumab plus taxane (median PFS: 13.7 months with trastuzumab plus taxane, 14.1 months with T-DM1, and 15.2 months with T-DM1 plus pertuzumab). Neither experimental arm showed PFS superiority to trastuzumab plus taxane. Response rate was 67.9% in patients who were treated with trastuzumab plus taxane, 59.7% with T-DM1, and 64.2% with T-DM1 plus pertuzumab; median response duration was 12.5 months, 20.7 months, and 21.2 months, respectively. The incidence of grade ≥ 3 adverse events was numerically higher in the control arm (54.1%) versus the T-DM1 arm (45.4%) and T-DM1 plus pertuzumab arm (46.2%). Numerically fewer patients discontinued treatment because of adverse events in the T-DM1 arms, and health-related quality of life was maintained for longer in the T-DM1 arms. Conclusion T-DM1 showed noninferior, but not superior, efficacy and better tolerability than did taxane plus trastuzumab for first-line treatment of HER2-positive, advanced breast cancer.

Purpose To identify factors related to who undergoes a prostate biopsy in a screened population and to estimate the impact of biopsy verification on risk factor–prostate cancer associations. Patients and Methods Men who were screened regularly from the placebo arms of two large prostate cancer prevention trials (Prostate Cancer Prevention Trial [PCPT] and Selenium and Vitamin E Cancer Prevention Trial [SELECT]) were examined to define incident prostate cancer cohorts. Because PCPT had an end-of-study biopsy, prostate cancer cases were categorized by a preceding prostate-specific antigen/digital rectal examination prompt (yes/no) and noncases by biopsy-proven negative status (yes v no). We estimated the association of risk factors (age, ethnicity, family history, body mass index, medication use) with prostate cancer and quantified differences in risk associations across cohorts. Results Men 60 to 69 years of age, those with benign prostatic hyperplasia, and those with a family history of prostate cancer were more likely, and those with a higher body mass index (≥ 25), diabetes, or a smoking history were less likely, to undergo biopsy, adjusting for age and longitudinal prostate-specific antigen and digital rectal examination. Medication use, education, and marital status also influenced who underwent biopsy. Some risk factor estimates for prostate cancer varied substantially across cohorts. Black ( v other ethnicities) had odds ratios (ORs) that varied from 1.20 for SELECT (community screening standards, epidemiologic-like cohort) to 1.83 for PCPT (end-of-study biopsy supplemented with imputed end points). Statin use in SELECT provided an OR of 0.65 and statin use in in PCPT provided an OR of 0.99, a relative difference of 34%. Conclusion Among screened men enrolled in prostate cancer prevention trials, differences in risk factor estimates for prostate cancer likely underestimate the magnitude of bias found in other cohorts with varying screening and biopsy recommendations and acceptance. Risk factors for prostate cancer derived from epidemiologic studies not only may be erroneous but may lead to misdirected research efforts.

Purpose Patients with relapsed metastatic germ cell tumor (GCT) can be cured with second-line and even third-line regimens. We report survival outcomes of patients treated with high-dose chemotherapy (HDCT) and peripheral-blood stem-cell transplantation (PBSCT) at Indiana University between 2004 and 2014. Patients and Methods We conducted a retrospective analysis of 364 consecutive patients with GCT who progressed after cisplatin-based combination chemotherapy and were subsequently treated with HDCT and PBSCT. Three hundred forty-one patients received two consecutive courses of HDCT consisting of 700 mg/m2 carboplatin and 750 mg/m2 etoposide, each for 3 consecutive days, and each followed by PBSCT. Twenty-three patients received only a single course of HDCT because of progressive disease or toxicity. Cox proportional hazards models were used to test predictors of disease progression. Results The median age was 32 years (range, 17 to 70 years). With a median follow-up of 3.3 years, the 2-year progression-free survival (PFS) was 60% (95% CI, 55% to 65%) and the 2-year overall survival was 66% (95% CI, 60% to 70%). Three hundred three patients received HDCT as second-line therapy with a 2-year PFS of 63% (95% CI, 57% to 68%), and 61 patients received HDCT as third-line or later therapy with a 2-year PFS of 49% (95% CI, 36% to 61%). In a multivariable analysis, factors associated with disease progression included use of HDCT as third-line or later therapy, platinum-refractory disease, mediastinal primary tumor site, nonseminoma histology, intermediate- or poor-risk disease at the time of GCT diagnosis, and human chorionic gonadotropin ≥ 1,000 mIU/mL at initiation of HDCT. There were nine treatment-related deaths. Secondary leukemia developed in five patients. Conclusion This large single-institution study demonstrates that patients with relapsed metastatic GCT are curable by HDCT plus PBSCT even when used in third-line or later therapy.

Purpose Hereditary factors play an important role in colorectal cancer (CRC) risk, yet the prevalence of germline cancer susceptibility gene mutations in patients with CRC unselected for high-risk features (eg, early age at diagnosis, personal/family history of cancer or polyps, tumor microsatellite instability [MSI], mismatch repair [MMR] deficiency) is unknown. Patients and Methods We recruited 1,058 participants who received CRC care in a clinic-based setting without preselection for age at diagnosis, personal/family history, or MSI/MMR results. All participants underwent germline testing for mutations in 25 genes associated with inherited cancer risk. Each gene was categorized as high penetrance or moderate penetrance on the basis of published estimates of the lifetime cancer risks conferred by pathogenic germline mutations in that gene. Results One hundred five (9.9%; 95% CI, 8.2% to 11.9%) of 1,058 participants carried one or more pathogenic mutations, including 33 (3.1%) with Lynch syndrome (LS). Twenty-eight (96.6%) of 29 available LS CRCs demonstrated abnormal MSI/MMR results. Seventy-four (7.0%) of 1,058 participants carried non-LS gene mutations, including 23 (2.2%) with mutations in high-penetrance genes (five APC, three biallelic MUTYH, 11 BRCA1/2, two PALB2, one CDKN2A, and one TP53), 15 of whom lacked clinical histories suggestive of their underlying mutation. Thirty-eight (3.6%) participants had moderate-penetrance CRC risk gene mutations (19 monoallelic MUTYH, 17 APC*I1307K, two CHEK2). Neither proband age at CRC diagnosis, family history of CRC, nor personal history of other cancers significantly predicted the presence of pathogenic mutations in non-LS genes. Conclusion Germline cancer susceptibility gene mutations are carried by 9.9% of patients with CRC. MSI/MMR testing reliably identifies LS probands, although 7.0% of patients with CRC carry non-LS mutations, including 1.0% with BRCA1/2 mutations.

Published: February 2017

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors’ suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 51-year-old women with left-sided, T2N1, grade 3, estrogen receptor– and progesterone receptor–negative, human epidermal growth factor receptor 2 (HER2)–positive breast cancer was referred to a cardio-oncology clinic for pre–cancer treatment cardiovascular risk assessment. The planned cancer treatment was 3 cycles of FEC (fluorouracil, epirubicin [100 mg/m2 per dose], and cyclophosphamide), followed by 3 cycles of concurrent docetaxel and trastuzumab, followed by maintenance trastuzumab to complete a 1-year course. Other than a prior history of hysterectomy, there was no relevant medical history. Her cardiac history was notable for the absence of prior cardiovascular disease, hypertension, diabetes, or hypercholesterolemia. She was a nonsmoker. At initial clinic visit, her blood pressure was 138/84 with an unremarkable cardiovascular examination. Her echocardiography demonstrated normal sinus rhythm at 73 beats per minute. During cancer treatment, she was observed with echocardiography (baseline left ventricular ejection fraction [LVEF], 61%; global longitudinal strain, −21.5%), cardiac magnetic resonance imaging (CMR, as part of an ongoing study), high-sensitivity troponin I, and B-type natriuretic peptide ( Table 1 ). Given that her baseline evaluations were negative at her initial visit, we discussed whether there were agents to prevent the rare, but serious, complication of congestive heart failure (HF) associated with anthracycline- and trastuzumab-based therapy.
