Abstract
BACKGROUND Approximately 95% of advanced colorectal cancer patients (CRC) have mismatch repair MMR-proficient (MMRp) tumors, which do not respond to PD1 blockade alone. Preclinical studies have shown that combined histone deacetylases (HDAC) and/or DNA methyltransferases (DNMT) inhibition can induce susceptibility to immune checkpoint therapy and inhibit tumor growth. We conducted a pilot trial evaluating PD-1 immune checkpoint inhibitor therapy in combination with DNMT and HDAC inhibitors in MMRp CRC. The study was designed with a biological endpoint of change in immune cell infiltration, to determine the optimal epigenetic combination that optimizes the tumor microenvironment. This trial was designed to test that hypothesis. RESULTS From January 2016 to November 2018, 27 patients were enrolled with median age of 57 (range 40-69) years. Median progression-free survival and overall survival were 2.79 months and 9.17, respectively. One patient in Arm C achieved a durable partial response by RECIST criteria, lasting for approximately 19 months. The most common treatment-related hematological adverse events in all arms were anemia (62%), lymphopenia (54%) and thrombocytopenia (35%), and non-hematological AEs were anorexia (65%), nausea (77%), and vomiting (73%). CONCLUSIONS The combination of 5-azacitidine and romidepsin with pembrolizumab was safe and tolerable in patients with advanced MMRp CRC, but with a minimal activity. Further mechanistic investigations are needed to understand epigenetic-induced immunologic shift and to expand the potential applicability of checkpoint inhibitors in this setting.

Abstract
BACKGROUND Immunotherapy has demonstrated a limited clinical efficacy in approximately 5% of cholangiocarcinoma. The main challenges for an effective immunotherapy response in cholangiocarcinoma arise from the tumor microenvironment, which is poorly understood. METHODS For a comprehensive analysis of the tumor microenvironment in cholangiocarcinoma, we performed multiplex immunohistochemistry with two 15-marker immune panels and Nanostring assays for a comprehensive analysis of 104 surgically resected cholangiocarcinomas including intrahepatic, hilar, and distal cholangiocarcinoma. We also validated some key findings with a batch integration analysis of published single cell RNA sequencing data. RESULTS This study found that natural killer cells occupy the largest immune cell compartment in cholangiocarcinoma. Granzyme-B+CD8+ effector T cells are significantly associated with better overall survival in both intrahepatic and distal cholangiocarcinoma. Above 85% of intrahepatic cholangiocarcinomas with higher density of PD-1-EOMES-CD8+ effector T cells are associated with long-term survival. However, only the density of PD-1-EOMES-CD8+ T cells in the tumor areas, but not in the peripheries of the tumors, is prognostic. In all three cholangiocarcinoma subtypes, T regulator cells are significantly associated with a poor prognosis; however, M1 and M2 tumor-associated macrophages or PD-L1+ tumor-associated macrophage demonstrate different prognostic values. Combining PD-L1+ M1 or M2, PD-L1- M1 or M2 tumor-associated macrophages, and T regulator cells to subgroup intrahepatic and distal cholangiocarcinoma, the prognosis is significantly better distinguished. Moreover, PD-L1- M2 tumor-associated macrophages is associated with a good prognosis in intrahepatic and distal cholangiocarcinoma, suggesting this subtype of M2 tumor-associated macrophages may be antitumoral. Interestingly, lower densities of various types of immunosuppressive cells are associated with decreased infiltration of effector T cells in distal and hilar cholangiocarcinoma, but not in intrahepatic cholangiocarcinoma. In intrahepatic cholangiocarcinoma, PD-L1+ tumor-associated macrophages exert their immunosuppressive function likely through promoting T cell exhaustion. CONCLUSIONS This study suggests that the densities of Granzyme-B+CD8+ effector T cells and non-exhausted PD-1-EOMES-CD8+ T cells and the PD-L1 status in the tumor-associated macrophages are prognostic makers in cholangiocarcinomas. The study also supports targeting PD-L1+ tumor-associated macrophages as the immunotherapy for cholangiocarcinoma.

Abstract
BACKGROUND Survivorship care plans (SCP) should outline pertinent information about cancer treatment and follow-up. METHODS We descriptively analyzed the content of 74 colorectal cancer SCPs completed as part of a randomized, controlled trial of SCPs at an academic and community cancer center. Surveillance recommendations were compared with American Cancer Society, American Society of Clinical Oncology and National Comprehensive Cancer Network guidelines. RESULTS SCP information provided in >80% of the plans included participant age, cancer diagnosis, details, and side-effects of treatment (surgery, chemotherapy, radiation) and health promotion recommendations. SCP content documented less frequently included predisposing conditions, genetic counseling/testing information and staging. Posttreatment surveillance recommendations were documented in >90% SCPs. For stage 2-3 cancer, rates of guideline concordant recommendations were 100% for colonoscopy surveillance (Year 1 only), 87% for imaging surveillance, 65% for carcinoembryonic antigen surveillance, and 33% for follow-up visits. Excluding colonoscopy, >15 unique recommendations were listed for each modality across stages and sites, with more variation at the academic site. CONCLUSIONS SCPs consistently recorded information about cancer diagnosis and treatment but omitted critical information about cancer-specific details denoting risk. Surveillance recommendations varied considerably between cancer centers. Future work to improve the consistency of surveillance recommendations documented in SCPs may be needed.

Abstract
Question Does ivosidenib treatment improve overall survival outcomes vs placebo among patients with chemotherapy-refractory cholangiocarcinoma with IDH1 mutation? Findings In this phase 3 randomized clinical trial including 187 previously treated patients with advanced cholangiocarcinoma with IDH1 mutation, ivosidenib treatment resulted in numerically improved overall survival benefits vs placebo, despite a high rate of crossover. Ivosidenib preserved certain quality of life subscales and was well tolerated. Meaning The combined efficacy data and tolerable safety profile, as well as corroborating quality of life data, support the clinical benefit of ivosidenib relative to placebo in cholangiocarcinoma with IDH1 mutation, which has an unmet need for new treatments. Importance Isocitrate dehydrogenase 1 (IDH1) variations occur in up to approximately 20% of patients with intrahepatic cholangiocarcinoma. In the ClarIDHy trial, progression-free survival as determined by central review was significantly improved with ivosidenib vs placebo. Objective To report the final overall survival (OS) results from the ClarIDHy trial, which aimed to demonstrate the efficacy of ivosidenib (AG-120)—a first-in-class, oral, small-molecule inhibitor of mutant IDH1—vs placebo for patients with unresectable or metastatic cholangiocarcinoma with IDH1 mutation. Design, Setting, and Participants This multicenter, randomized, double-blind, placebo-controlled, clinical phase 3 trial was conducted from February 20, 2017, to May 31, 2020, at 49 hospitals across 6 countries among patients aged 18 years or older with cholangiocarcinoma with IDH1 mutation whose disease progressed with prior therapy. Interventions Patients were randomized 2:1 to receive ivosidenib, 500 mg, once daily or matched placebo. Crossover from placebo to ivosidenib was permitted if patients had disease progression as determined by radiographic findings. Main Outcomes and Measures The primary end point was progression-free survival as determined by blinded independent radiology center (reported previously). Overall survival was a key secondary end point. The primary analysis of OS followed the intent-to-treat principle. Other secondary end points included objective response rate, safety and tolerability, and quality of life. Results Overall, 187 patients (median age, 62 years [range, 33-83 years]) were randomly assigned to receive ivosidenib (n = 126; 82 women [65%]; median age, 61 years [range, 33-80 years]) or placebo (n = 61; 37 women [61%]; median age, 63 years [range, 40-83 years]); 43 patients crossed over from placebo to ivosidenib. The primary end point of progression-free survival was reported elsewhere. Median OS was 10.3 months (95% CI, 7.8-12.4 months) with ivosidenib vs 7.5 months (95% CI, 4.8-11.1 months) with placebo (hazard ratio, 0.79 [95% CI, 0.56-1.12]; 1-sided P = .09). When adjusted for crossover, median OS with placebo was 5.1 months (95% CI, 3.8-7.6 months; hazard ratio, 0.49 [95% CI, 0.34-0.70]; 1-sided P < .001). The most common grade 3 or higher treatment-emergent adverse event (≥5%) reported in both groups was ascites (11 patients [9%] receiving ivosidenib and 4 patients [7%] receiving placebo). Serious treatment-emergent adverse events considered ivosidenib related were reported in 3 patients (2%). There were no treatment-related deaths. Patients receiving ivosidenib reported no apparent decline in quality of life compared with placebo. Conclusions and Relevance This randomized clinical trial found that ivosidenib was well tolerated and resulted in a favorable OS benefit vs placebo, despite a high rate of crossover. These data, coupled with supportive quality of life data and a tolerable safety profile, demonstrate the clinical benefit of ivosidenib for patients with advanced cholangiocarcinoma with IDH1 mutation.

Abstract
The combination of drugs targeting Ral and PI3K/AKT signaling has antitumor efficacy in preclinical models of pancreatic cancer. We combined dinaciclib (small molecule cyclin dependent kinase inhibitor with MK-2206 (Akt inhibitor) in patients with previously treated/metastatic pancreatic cancer. Patients were treated with dinaciclib (6-12 mg/m2 i.v.) and MK-2206 (60-135 mg p.o.) weekly. Tumor biopsies were performed to measure pAKT, pERK, and Ki67 at baseline and after one completed cycle (dose level 2 and beyond). Thirty-nine patients participated in the study. The maximum tolerated doses were dinaciclib 9 mg/m2 and MK-2206 135 mg. Treatment-related grade 3 and 4 toxicities included neutropenia, lymphopenia, anemia, hyperglycemia, hyponatremia, and leukopenia. No objectives responses were observed. Four patients (10%) had stable disease as their best response. At the recommended dose, median survival was 2.2 months. Survival rates at 6 and 12 months were 11% and 5%, respectively. There was a nonsignificant reduction in pAKT composite scores between pretreatment and post-treatment biopsies (mean 0.76 vs. 0.63; P = 0.635). The combination of dinaciclib and MK-2206 was a safe regimen in patients with metastatic pancreatic cancer, although without clinical benefit, possibly due to not attaining biologically effective doses. Given the strong preclinical evidence of Ral and AKT inhibition, further studies with better tolerated agents should be considered.

Abstract
BACKGROUND Isocitrate dehydrogenase 1 (IDH1) mutations occur in approximately 13% of patients with intrahepatic cholangiocarcinoma, a relatively uncommon cancer with a poor clinical outcome. The aim of this international phase 3 study was to assess the efficacy and safety of ivosidenib (AG-120)-a small-molecule targeted inhibitor of mutated IDH1-in patients with previously treated IDH1-mutant cholangiocarcinoma. METHODS This multicentre, randomised, double-blind, placebo-controlled, phase 3 study included patients from 49 hospitals in six countries aged at least 18 years with histologically confirmed, advanced, IDH1-mutant cholangiocarcinoma who had progressed on previous therapy, and had up to two previous treatment regimens for advanced disease, an Eastern Cooperative Oncology Group performance status score of 0 or 1, and a measurable lesion as defined by Response Evaluation Criteria in Solid Tumors version 1.1. Patients were randomly assigned (2:1) with a block size of 6 and stratified by number of previous systemic treatment regimens for advanced disease to oral ivosidenib 500 mg or matched placebo once daily in continuous 28-day cycles, by means of an interactive web-based response system. Placebo to ivosidenib crossover was permitted on radiological progression per investigator assessment. The primary endpoint was progression-free survival by independent central review. The intention-to-treat population was used for the primary efficacy analyses. Safety was assessed in all patients who had received at least one dose of ivosidenib or placebo. Enrolment is complete; this study is registered with ClinicalTrials.gov, NCT02989857. FINDINGS Between Feb 20, 2017, and Jan 31, 2019, 230 patients were assessed for eligibility, and as of the Jan 31, 2019 data cutoff date, 185 patients were randomly assigned to ivosidenib (n=124) or placebo (n=61). Median follow-up for progression-free survival was 6·9 months (IQR 2·8-10·9). Progression-free survival was significantly improved with ivosidenib compared with placebo (median 2·7 months [95% CI 1·6-4·2] vs 1·4 months [1·4-1·6]; hazard ratio 0·37; 95% CI 0·25-0·54; one-sided p<0·0001). The most common grade 3 or worse adverse event in both treatment groups was ascites (four [7%] of 59 patients receiving placebo and nine [7%] of 121 patients receiving ivosidenib). Serious adverse events were reported in 36 (30%) of 121 patients receiving ivosidenib and 13 (22%) of 59 patients receiving placebo. There were no treatment-related deaths. INTERPRETATION Progression-free survival was significantly improved with ivosidenib compared with placebo, and ivosidenib was well tolerated. This study shows the clinical benefit of targeting IDH1 mutations in advanced, IDH1-mutant cholangiocarcinoma. FUNDING Agios Pharmaceuticals.

Abstract
BACKGROUND Fibroblast growth factor receptor (FGFR) 2 gene alterations are involved in the pathogenesis of cholangiocarcinoma. Pemigatinib is a selective, potent, oral inhibitor of FGFR1, 2, and 3. This study evaluated the safety and antitumour activity of pemigatinib in patients with previously treated, locally advanced or metastatic cholangiocarcinoma with and without FGFR2 fusions or rearrangements. METHODS In this multicentre, open-label, single-arm, multicohort, phase 2 study (FIGHT-202), patients aged 18 years or older with disease progression following at least one previous treatment and an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 recruited from 146 academic or community-based sites in the USA, Europe, the Middle East, and Asia were assigned to one of three cohorts: patients with FGFR2 fusions or rearrangements, patients with other FGF/FGFR alterations, or patients with no FGF/FGFR alterations. All enrolled patients received a starting dose of 13·5 mg oral pemigatinib once daily (21-day cycle; 2 weeks on, 1 week off) until disease progression, unacceptable toxicity, withdrawal of consent, or physician decision. The primary endpoint was the proportion of patients who achieved an objective response among those with FGFR2 fusions or rearrangements, assessed centrally in all patients who received at least one dose of pemigatinib. This study is registered with ClinicalTrials.gov, NCT02924376, and enrolment is completed. FINDINGS Between Jan 17, 2017, and March 22, 2019, 146 patients were enrolled: 107 with FGFR2 fusions or rearrangements, 20 with other FGF/FGFR alterations, 18 with no FGF/FGFR alterations, and one with an undetermined FGF/FGFR alteration. The median follow-up was 17·8 months (IQR 11·6-21·3). 38 (35·5% [95% CI 26·5-45·4]) patients with FGFR2 fusions or rearrangements achieved an objective response (three complete responses and 35 partial responses). Overall, hyperphosphataemia was the most common all-grade adverse event irrespective of cause (88 [60%] of 146 patients). 93 (64%) patients had a grade 3 or worse adverse event (irrespective of cause); the most frequent were hypophosphataemia (18 [12%]), arthralgia (nine [6%]), stomatitis (eight [5%]), hyponatraemia (eight [5%]), abdominal pain (seven [5%]), and fatigue (seven [5%]). 65 (45%) patients had serious adverse events; the most frequent were abdominal pain (seven [5%]), pyrexia (seven [5%]), cholangitis (five [3%]), and pleural effusion (five [3%]). Overall, 71 (49%) patients died during the study, most frequently because of disease progression (61 [42%]); no deaths were deemed to be treatment related. INTERPRETATION These data support the therapeutic potential of pemigatinib in previously treated patients with cholangiocarcinoma who have FGFR2 fusions or rearrangements. FUNDING Incyte Corporation.

Abstract
Background Mismatch repair proficient (MMRp) colorectal cancer (CRC) has been refractory to single‐agent programmed cell death protein 1 (PD1) inhibitor therapy. Colon GVAX is an allogeneic, whole‐cell, granulocyte‐macrophage colony‐stimulating factor ‐secreting cellular immunotherapy that induces T‐cell immunity against tumor‐associated antigens and has previously been studied in combination with low‐dose cyclophosphamide (Cy) to inhibit regulatory T cells. Methods We conducted a single‐arm study of GVAX/Cy in combination with the PD1 inhibitor pembrolizumab in patients with advanced MMRp CRC. Patients received pembrolizumab plus Cy on day 1, GVAX on day 2, of a 21‐day cycle. The primary endpoint was the objective response rate by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Secondary objectives included safety, overall survival, progression‐free survival, changes in carcinoembryonic antigen (CEA) levels, and immune‐related correlates. Results Seventeen patients were enrolled. There were no objective responses, and the disease control rate was 18% by RECIST 1.1. The median progression‐free survival was 82 days (95% confidence interval [CI], 48‐97 days) and the median overall survival was 213 days (95% CI 179‐441 days). Biochemical responses (≥30% decline in CEA) were observed in 7/17 (41%) of patients. Grade ≥ 3 treatment‐related adverse events were observed in two patients (hemolytic anemia and corneal transplant rejection). Paired pre‐ and on‐treatment biopsy specimens showed increases in programmed death‐ligand 1 expression and tumor necrosis in a subset of patients. Conclusions GVAX/Cy plus pembrolizumab failed to meet its primary objective in MMRp CRC. Biochemical responses were observed in a subset of patients and have not previously been observed with pembrolizumab monotherapy in MMRp CRC, indicating that GVAX may modulate the antitumor immune response.

Abstract
BACKGROUND Readmission has received attention as a potential healthcare quality metric. No studies have investigated the relationship between readmission and survival in patients undergoing rectal cancer surgery. The aims of this study were to identify factors associated with 30-day readmission after rectal cancer surgery and to determine the impact of readmission on overall survival (OS). METHODS Patients who underwent surgical treatment for rectal/rectosigmoid adenocarcinoma stages I-IV were identified using the National Cancer Database (2004-2014). Multivariable logistic regression was used to identify factors for readmission. 2:1 nearest neighbor caliper matching without replacement was used to ensure similarity of patients being compared. Survival analyses were performed using Kaplan-Meier method along with log-rank test and Cox proportional hazards model. RESULTS Of 110,167 patients, 7045 (6.39%) were readmitted. Factors associated with readmission included higher Charlson comorbidity score, non-private or no insurance, procedure type, hospitals in the Northeast, South, and Midwest regions, and prolonged length of stay. Within the matched cohort (13,756 non-readmitted and 6878 readmitted), readmitted patients had worse 5- and 10-year OS regardless of cancer stage (p < 0.001) and procedure type. Five- and 10-year OS were 58.98% and 41.01% for readmitted patients, 64.96% and 43.50% for non-readmitted patients. Readmitted patients had shorter OS by 13.14 months and increased risk of mortality (HR 1.20, 95% CI 1.15-1.25, p < 0.001). CONCLUSIONS Thirty-day readmission after rectal cancer surgery is associated with decreased OS. Efforts to reduce readmissions should be considered to advance cancer care and enhance the potential for improved patient survival.

Abstract
Abstract
Background: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy, which is the third leading cause of cancer related deaths in the United Sates. As the number of new cases continues to rise, the current treatments of surgical resection, chemotherapy, and radiation have not drastically improved PDAC survival rates. PDAC is known to have a quiescent immune microenvironment, which is resistant to single-agent checkpoint inhibitors. We identified a combination approach using immune checkpoint inhibition and immune activing agonists to prime the tumor microenvironment (TME) to activate T-cells in order to overcome this “cold” environment. Here we investigate spatial relationships between CD8+, PD-1+ (programmed cell death protein), and PD-L1+ (programmed cell death ligand) cells in the TME following single agent and combinatorial immunotherapy protocols.
Experimental Procedures: Our cohort includes 17 surgically resected patient tumor specimens from formalin-fixed paraffin-embedded tissue blocks. These patients either received GM-CSF vaccine (GVAX) with or without immune checkpoint inhibitor, anti-PD-1. Of the 11 patients analyzed, six received GAVX with anti-PD-1 while the others received GVAX alone. Automated immunohistochemical staining was performed for CD8, PD-1, and PD-L1. Analysis was performed using HALO image analysis software (Indica Labs) (HALO v2.0.1145.31). Proximal distance (Nearest Neighbor Analysis) of CD8+ to PD-1+ cells, CD8+ to PD-L1+ cells, PD-1+ to PD-L1+ cells within the tumor area was measured for each patient to generate average distance between cell types.
Results: Of the 17 PDAC patients in our cohort, 11 patient specimens were analyzed. Nearest Neighbor Analysis between the two groups shows there is a trend of increased distance between CD8+ cells and PD-1+ cells and between CD8+ cells and PD-L1+ cells in patients receiving GVAX and anti-PD-1 compared to GVAX alone (p=0.032 and n.s., respectively). Proximal distance analysis of PD-1+ cells to PD-L1+ cells is ongoing.
Conclusions: PDAC remains a considerable diagnostic and therapeutic challenge due to its poor survival outcomes. However, immunotherapy may provide an alternative strategy to improve survival for PDAC patients. Our results suggest that monotherapy with GVAX versus combination therapy with GVAX plus anti-PD-L1 leads to differences in the spatial relationship between CD8+ cells and PD-1+ and PD-L1+ cells, specifically, greater distance between CD8+ T cells and PD-L1+ and PD-1+ cells, suggesting the potential for greater functionality and less direct cell/cell suppression. More broadly, our results demonstrate the ability to detect differences in patient groups based on spatial analysis of distance between cell types, a technique that can be applied generally to the correlative analyses of immunotherapy protocols.. Further analysis of spatial relationships and immune cell infiltration in the TME following immunotherapy will help elucidate how these treatment protocols impact the architecture of the TME and will help guide therapeutic approaches to immunotherapy in pancreatic cancer. We demonstrate a technique of spatial analysis that will aid in dissecting these cellular relationships.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) represents an immune quiescent tumor that is resistant to immune checkpoint inhibitors. Previously, our group has shown that a GM-CSF-secreting allogenic pancreatic tumor cell vaccine (GVAX) may prime the tumor microenvironment by inducing intratumoral T cell infiltration. Here, we show that untreated PDACs express minimal indoleamine-2,3-dioxygenase (IDO1); however, GVAX therapy induced IDO1 expression on tumor epithelia as well as vaccine-induced tertiary lymphoid aggregates. IDO1 expression plays a role in regulating the polarization of Th1, Th17, and possibly T regulatory cells in PDAC tumors. IDO1 inhibitor enhanced antitumor efficacy of GVAX in a murine model of PDACs. The combination of vaccine and IDO1 inhibitor enhanced intratumoral T cell infiltration and function, but adding anti-PD-L1 antibody to the combination did not offer further synergy and in fact may have had a negative interaction, decreasing the number of intratumoral effector T cells. Additionally, IDO1 inhibitor in the presence of vaccine therapy did not significantly modulate intratumoral myeloid-derived suppressor cells quantitatively, but diminished their suppressive effect on CD8+ proliferation. Our study supports the combination of IDO1 inhibitor and vaccine therapy; however, it does not support the combination of IDO1 inhibitor and anti-PD-1/PD-L1 antibody for T cell-inflamed tumors such as PDACs treated with vaccine therapy.

Abstract
The connection between inflammation and malignancy has long been recognized in gastric and esophageal cancers. Given the considerable success of immune checkpoint inhibitors in other tumor types, for example, lung cancer and melanoma, much attention is being paid to furthering their role in gastric and esophageal cancers. The Cancer Genome Atlas has provided further details of the molecular heterogeneity of these tumors, which may help predict responsiveness to immune checkpoint inhibitors. This article discusses the rationale for investigating these agents in gastroesophageal cancer and summarizes the relevant clinical trial data and ongoing studies.

Abstract
Immunotherapy shows promise for positively changing the landscape of the management of many advanced solid tumors, including gastrointestinal (GI) malignancies. Many of these developments have been focused on vaccine-based, monoclonal antibody therapies and more recently, checkpoint inhibitors, although many small molecule inhibitors can function as immunomodulators. Small molecule compounds have several advantages over conventional immunotherapeutic agents including: ease of production and the potential for oral administration. There is a potential niche for small molecule immunomodulators to enhance the efficacy of existing immunotherapeutic and cytotoxic agents. This article focuses on two categories of small molecule compounds with immunomodulatory effects: IDO and MEK inhibitors. Indoleamine -2, 3- dioxygenase (IDO) is known for its effects in tumor immunity. IDO inhibitors are generally well-tolerated and have the potential to enhance anti-tumor responses when combined with checkpoint inhibitors. MEK inhibitors affect signal transduction of the RAS-RAF-MEK pathway and numerous MEK inhibitors are currently being investigated in solid tumors. Small molecule immunomodulators are currently being investigated for their potential role in augmenting the effects of conventional immunotherapeutic agents although further research is required to identify those patients most likely to respond to combination therapy.

Abstract
We describe a 62-year-old of Egyptian origin who presented with sudden, severe and symptomatic anemia requiring hospitalization shortly after beginning concurrent radiation and temozolomide for his newly diagnosed glioblastoma. He had also recently been started on steroids, anticonvulsants and Pneumocystis jirovecii prophylaxis. He was ultimately diagnosed with G6PD deficiency with an acute hemolytic anemia precipitated by dapsone. Screening for G6PD deficiency should be considered in high-risk patient populations where P. jirovecii prophylaxis is planned.

Abstract
The anatomical locations of upper gastrointestinal (GI) tumors have changed remarkably in the western world and reflect the increasing impact of obesity and gastroesophageal (GE) reflux rather than infectious etiologies. Incidence rates of GE tumors are rising rapidly and survival rates for patients with metastatic disease remain poor. Traditionally, cytotoxic chemotherapy has had some survival advantages but increasingly complex combination regimens are limited by toxicities. The advent of molecularly targeted therapy has provided additional options for patients with advanced disease including trastuzumab and ramucirumab. There has also been detailed molecular characterization of upper GI tumors which hopefully will result in improved tailoring of clinical trial design accounting for the heterogeneity inherent in GE tumors. While numerous targeted therapies are currently being studied in clinical trials, there is much excitement regarding the role of immunotherapy in GE cancers. Although further investigation is warranted, it represents a promising avenue for patients with advanced GE tumors.

Abstract
OBJECTIVE Our purpose was to investigate the efficacy and safety of 0.1% topical tacrolimus in erosive or ulcerative oral lichen planus. METHODS This was an open-label, noncomparative study conducted in an outpatient oral medicine unit in London, United Kingdom. The study covered an 8-week period with a 22-week follow-up after cessation of therapy. Nineteen patients, aged 28 to 87 years with biopsy-proven oral lichen planus refractory to, or dependent on, systemic immunosuppressive agents, were enrolled. Seventeen patients (89%) completed the study. Application of 0.1% tacrolimus was administered to all symptomatic oral mucosal lesions. Clinical review took place 1, 3, 5, 7, and 8 weeks after commencing therapy. Alleviation of symptoms was evaluated by using a visual analogue scale as well as the McGill Pain and Oral Health Impact profile questionnaires. The extent of the oral mucosal erosion or ulceration was directly measured by the same clinician at all visits. Safety assessments included monitoring of adverse events, complete blood cell count, renal and hepatic clinical chemistry, and tacrolimus blood concentrations. RESULTS Tacrolimus caused a statistically significant improvement in symptoms within 1 week of commencement of therapy. A mean decrease of 73.3% occurred in the area of ulceration over the 8-week study period. Local irritation (in 6 subjects, 35%) was the most commonly reported adverse effect. Laboratory values showed no significant changes with time. Therapeutic levels of tacrolimus were demonstrated in 8 subjects but were unrelated to the extent of oral mucosal involvement. Thirteen of 17 patients suffered a relapse of oral lichen planus within 2 to 15 weeks of cessation of tacrolimus therapy. CONCLUSION Topical tacrolimus is effective therapy for erosive or ulcerative oral lichen planus.

Abstract
OBJECTIVE Previous randomized controlled trials for treatment of rheumatoid arthritis (RA) with acid-soluble chicken and bovine type II collagen (CII) have produced conflicting results. This randomized, double-blind, controlled trial examined the therapeutic effect of bovine CII tablets in RA. METHODS CII tablets were prepared by adsorption onto a lactose base. Patients with a duration of RA of > or = 2 years and who had failed treatment with at least 1 slow-acting drug were recruited, provided that they had active arthritis. Patients were randomly assigned to receive either 0.05 mg, 0.5 mg, or 5 mg of CII or placebo daily for 6 months. All slow-acting drugs were stopped at least 4 weeks before starting CII, although prednisolone was permitted at dosages < 10 mg/day. Clinical assessments were performed at screening and at 0, 1, 4, 8, 12, 16, 20, and 24 weeks of treatment. RESULTS Fifty-five patients were recruited. Initially, there were no significant differences in mean Disease Activity Scores between groups. At 24 weeks, there was a significant difference (P = 0.041, by Kruskal-Wallis analysis of variance); the major components of this difference were attributable to relatively large decreases in the 0.5 mg CII group (19% of initial values) and to minimal decreases in patients receiving placebo (3% of initial values). Twenty patients had American College of Rheumatology 20% responses; 11 of these were in the 0.5 mg CII group and 3 were in each of the other groups, a significant difference (chi2 = 14.6, P = 0.002). There was no significant difference in any clinical measure between the placebo, 0.05 mg CII, and 5 mg CII groups. There were no side effects associated with CII treatment. CONCLUSION Treatment with 0.5 mg/day of bovine CII is well tolerated and produces small, but significant, disease improvement in RA. However, the therapeutic window is narrow. The difference between our results and those of other trials may relate to the dose, species, and formulation of the CII.

Abstract
A 15% aminosidine sulphate (AS)/10% urea/white soft paraffin (WSP) ointment cured all Leishmania major lesions on Balb/C mice following topical application for 10 d. Some relapses were observed 10 weeks after treatment. AS alone in WSP ointment was also highly effective. The ointment containing urea was non-irritant to mice, whereas ointments containing quaternary ammonium compounds were irritant. The 15% AS/10% urea/WSP ointment was not effective in the treatment of L. mexicana or L. panamensis lesions on Balb/C mice, no cure being observed.
