Effects of dual sofosbuvir/daclatasvir therapy on, chronic hepatitis C infected, survivors of childhood malignancy. World J Clin Cases 2019; 7:2247-2255. [PMID: 31531319 PMCID: PMC6718790 DOI: 10.12998/wjcc.v7.i16.2247] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Revised: 06/13/2019] [Accepted: 07/03/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Childhood cancer survivors are potentially at a higher risk of infection with hepatitis C virus (HCV). The effects of all-oral direct-acting antiviral therapy (DAA) on both the HCV infection as well as the state of cancer remission have not been well investigated in this population.
AIM To test the effects of dual sofosbuvir/daclatasvir (SOF/DCV) therapy in the treatment of chronic HCV in survivors of hematologic malignancy in pediatric age group.
METHODS We conducted a prospective, uncontrolled, open-label multicenter study. A total of 20 eligible, chronic HCV, genotype-4, infected children who had been in continuous complete remission from hematologic cancer (leukemia/lymphoma) for at least one year were included in the study. All patients were treated with combined SOF/DCV for 12 wk. Patients were monitored throughout the study till 12 wk after end of treatment for safety and efficacy outcomes including the sustained virologic response 12 (SVR12) rate, hematological indices, liver and kidney functions.
RESULTS The intent-to-treat SVR12 rate was 20 of 20 (100%; 95%CI: 84%-100%). All patients showed normalized liver enzymes from week-4. All hematological indices, liver and kidney functions were kept normal throughout the study. No fatalities or treatment-emergent serious or severe adverse events were reported throughout the study.
CONCLUSION SOF/DCV combined therapy could be used safely and effectively in the treatment of chronic HCV genotype-4 infection in leukemia/lymphoma treated children. No relapses were detected during treatment and throughout the follow up period for either the original malignant disease or the HCV infection.

Direct-Acting Antivirals in Hepatitis C Virus-Associated Diffuse Large B-cell Lymphomas. Oncologist 2019; 24:e720-e729. [PMID: 30552159 PMCID: PMC6693710 DOI: 10.1634/theoncologist.2018-0331] [Citation(s) in RCA: 43] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2018] [Accepted: 11/06/2018] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND International guidelines suggest hepatitis C virus (HCV) eradication by direct-acting antivirals (DAAs) after first-line immunochemotherapy (I-CT) in patients with HCV-positive diffuse large B-cell lymphoma (DLBCL), although limited experiences substantiate this recommendation. Moreover, only a few data concerning concurrent administration of DAAs with I-CT have been reported. SUBJECTS, MATERIALS, AND METHODS We analyzed hematological and virological outcome and survival of 47 consecutive patients with HCV-positive DLBCL treated at 23 Italian and French centers with DAAs either concurrently (concurrent cohort [ConC]: n = 9) or subsequently (sequential cohort [SeqC]: n = 38) to first-line I-CT (mainly rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone [R-CHOP]-like). RESULTS Median age was 61 years, 89% of patients had stage III/IV, and 25% presented evidence of cirrhosis. Genotype was 1 in 56% and 2 in 34% of cases. Overall, 46 of 47 patients obtained complete response to I-CT. All patients received appropriate DAAs according to genotype, mainly sofosbuvir-based regimens (n = 45). Overall, 45 patients (96%) achieved sustained virological response, 8 of 9 in ConC and 37 of 38 in SeqC. DAAs were well tolerated, with only 11 patients experiencing grade 1-2 adverse events. Twenty-three patients experienced hepatic toxicity (grade 3-4 in seven) following I-CT in SeqC, compared to only one patient in ConC. At a median follow-up of 2.8 years, two patients died (2-year overall survival, 97.4%) and three progressed (2-year progression-free survival, 93.1%). CONCLUSION Excellent outcome of this cohort of HCV-positive DLBCL suggests benefit of HCV eradication by DAAs either after or during I-CT. Moreover, concurrent DAAs and R-CHOP administration appeared feasible, effective, and ideally preferable to deferred administration of DAAs for the prevention of hepatic toxicity. IMPLICATIONS FOR PRACTICE Hepatitis C virus (HCV)-associated diffuse large B-cell lymphomas (DLBCLs) represent a great therapeutic challenge, especially in terms of hepatic toxicity during immune-chemotherapy (I-CT) and long-term hepatic complications. The advent of highly effective and toxicity-free direct-acting antivirals (DAAs) created an exciting opportunity to easily eradicate HCV shortly after or in concomitance with first-line immunochemotherapy (usually R-CHOP). This retrospective international study reports the real-life use of the combination of these two therapeutic modalities either in the concurrent or sequential approach (DAAs after I-CT) in 47 patients. The favorable reported results on long-term outcome seem to support the eradication of HCV with DAAs in all patients with HCV-positive DLBCL. Moreover, the results from the concurrent approach were effective and safe and displayed an advantage in preventing hepatic toxicity during I-CT.

Abstract
BACKGROUND AND AIMS Direct antiviral agents have greatly improved therapeutic options for chronic hepatitis C. Indeed, former "difficult-to-treat" patients can now be treated and can achieve sustained response. Hepatitis C virus (HCV) is associated with hepatocellular carcinoma and with B-cell non-Hodgkin lymphoma (B-NHL). Other malignancies have been reported to be associated with HCV infection albeit with various grades of evidence. Antineoplastic treatment is often reduced or suspended in HCV-positive cancer patients to avoid "HCV reactivation." In this setting, antiviral therapy combined with antineoplastic protocols may improve the outcome. For this reason, we conducted a systematic review and a meta-analysis to update the association between HCV infection and non-hepatocellular malignancies, and to shed light on the effects exerted by antiviral treatment on the natural history of oncological diseases. METHODS Relevant studies were identified by searching PUBMED, EMBASE and MEDLINE up to 1 August 2018. Pooled risk estimates were calculated with random-effects models according to PRISMA guidelines. RESULTS A total of 58 studies were included in the analysis: 27 studies of the association between HCV and B-NHL(OR 3.36; 95% CI 2.40-4.72;P < 0.00001);13 studies of the association between sustained virological response and progression-free survival (PFS) in B-NHL patients(OR 9.34; 95% CI 4.90-17.79; P < 0.00001); 13 studies of the association between HCV and intrahepatic-cholangio-carcinoma (OR 3.95;95% CI 2.25-6.94; P < 0.00001); and 5 studies of the association between HCV infection and pancreatic adeno-carcinoma(OR 1.60; 95% CI:1.25-2.04; P = 0.0002). CONCLUSIONS This study updates the strong association between B-NHL and HCV infection, confirms the association between HCV and non-hepatocellular tumours, and demonstrates a very strong association between viral eradication and a better outcome of HCV-positive B-NHL.

Abstract
BACKGROUND AND AIMS It has been demonstrated that 1,25-hydroxyvitamin-D3-24-hydroxylase, encoded by CYP24A1 gene, is a key enzyme that neutralizes the active vitamin D3 metabolite 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] in response to hepatitis C virus (HCV) infection. This study aimed to investigate whether CYP24A1 genetic variation is associated with HCV infection outcomes. METHODS 848 HCV chronically infected subjects, 507 natural clearance subjects, and 1017 uninfected controls were enrolled. Nine single nucleotide polymorphisms (SNPs) in theCYP24A1 gene were genotyped using the Sequenom MassARRAY platform. RESULTS After adjusting for age, gender, and routes of infection, logistic regression analyses showed that rs6013897-A was associated with an elevated risk of HCV infection (P<0.05). In addition, this study has also demonstrated that rs6068816-T significantly reduced the risk of chronic HCV infection, while rs3787557-C, rs6022999-G, and rs2248359-T significantly increased the risk of chronic HCV infection (all P<0.05). Haplotype analysis suggested that, compared to the most frequent Trs6068816Trs3787557Ars6022999Crs2248359 haplotype, the CTGT haplotype (adjusted OR=1.376, 95% CI=1.092-1.735, P=0.007) and CCAC haplotype (adjusted OR=1.483, 95% CI=1.139-1.929, P=0.003) were associated with an increased risk of chronic HCV infection. CONCLUSION These findings indicate that SNPs in CYP24A1 gene may contribute to the risk of HCV infection and chronic HCV infection among a high-risk Chinese population.

Abstract
BACKGROUND To summarise the evidence on the associations between body mass index (BMI) and BMI in early adulthood, height, waist circumference (WC) and waist-to-hip ratio (WHR), and risk of lympho-haematopoietic cancers. METHOD We conducted a meta-analysis of prospective studies and identified relevant studies published up to December 2017 by searching PubMed. A random-effects model was used to calculate dose-response summary relative risks (RRs). RESULTS Our findings showed BMI, and BMI in early adulthood (aged 18-21 years) is associated with the risk of Hodgkin's and non-Hodgkin's lymphoma (HL and NHL), diffuse large beta-cell lymphoma (DLBCL), Leukaemia including acute and chronic myeloid lymphoma (AML and CML), and chronic lymphocytic leukaemia (CLL) and multiple myeloma (MM). The summary RR per 5 kg/m2 increase in BMI were 1.12 [95% confidence interval (CI): 1.05-1.20] for HL, 1.05 (95% CI: 1.03-1.08) for NHL, 1.11 (95% CI: 1.05-1.16) for DLBCL, 1.06 (95% CI: 1.03-1.09) for ML, 1.09 (95% CI: 1.03-1.15) for leukaemia, 1.13 (95% CI: 1.04-1.24) for AML, 1.13 (95% CI: 1.05-1.22) for CML and 1.04 (95% CI: 1.00-1.09) for CLL, and were1.12 (95% CI: 1.05-1.19) for NHL, 1.22 (95% CI: 1.09-1.37) for DLBCL, and 1.19 (95% CI: 1.03-1.38) for FL for BMI in early adulthood analysis. Results on mortality showed a 15%, 16% and 17% increased risk of NHL, MM and leukaemia, respectively. Greater height increased the risk of NHL by 7%, DLBCL by 10%, FL by 9%, MM by 5% and Leukaemia by 7%. WHR was associated with increased risk of DLBCL by 12%. No association was found between higher WC and risk of MM. CONCLUSION Our results revealed that general adiposity in adulthood and early adulthood, and greater height may increase the risk of almost all types of lympho-haematopoietic cancers and this adds to a growing body of evidence linking body fatness to several types of cancers.

Abstract
BACKGROUND Data are sparse on treatment of chronic hepatitis C virus (HCV) in cancer patients. We evaluated the efficacy and safety of sofosbuvir-based therapy (SOFBT) in cancer patients. METHODS Patients treated with SOFBT at our center during 2014-2017 were included in a prospective observational study. Efficacy [sustained virologic response at 12 weeks after the end of treatment (SVR12)], cancer-related outcomes and adverse events (AEs) were assessed. RESULTS We included 153 patients. Most were men (109; 71%), white (92; 60%), non-cirrhotic (105; 69%), and with HCV genotype 1 (110; 72%). The most common cancers were hepatocellular carcinoma (HCC) (27; 18%) and multiple myeloma (14; 9%). The overall SVR12 rate was 91% (128/141). SVR12 was 100% in patients treated with ledipasvir/sofosbuvir for 8 weeks. Of the 32 patients initially excluded from cancer clinical trials because of HCV, 27 (84%) were granted cancer therapy access after starting SOFBT. Six patients with indolent non-Hodgkin's lymphoma (NHL) received SOFBT without cancer treatment. Two achieved complete remission, one had partial remission, and two had stable cancer. Within 6 months after SOFBT, 5% (6/121) of patients in remission or with stable cancer, had progression or recurrence (two with HCC and one each with esophageal cancer, cholangiocarcinoma, NHL, and tonsillar cancer). No de novo HCCs occurred. AEs were most commonly grade 1-2 (90%). CONCLUSIONS SOFBT in HCV-infected cancer patients is effective and safe, may permit access to investigational cancer therapy expanding treatment options, may induce remission of NHL, and may be used for 8 weeks.

Abstract
OBJECTIVE Identification of new molecular markers to enhance early diagnosis, prognosis and/or treatment of hepatocellular carcinoma (HCC) is a need. TOM34 (34 kDa-translocase of the outer mitochondrial membrane) protein expression deregulation has demonstrated to be involved in the growth of many cancers. Here, we aimed at evaluating serum TOM34 and some heat shock proteins (HSPA4, HSPA1B, and HSP90AA1) expressions in hepatitis C virus (HCV)-related cirrhosis and HCV-induced HCC relative to controls and correlating these expressions to the clinicopathological data. METHODS Serum specimens were collected from 90 patients with HCV associated complications (30 cirrhotic, 30 early HCC and 30 late HCC) and 60 controls. Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was performed for relative quantification of the four target genes using the Livak method. In silico network analysis was also executed to explore the contribution of the genes in liver cancer. RESULTS The serum TOM34 and HSP90AA1 transcripts were significantly upregulated in HCC patients compared to cirrhotic ones with more up-regulation in late HCC patients. Receiver operating characteristic analysis showed the optimum cutoff value of 0.625 corresponding to 71.7% sensitivity and 56.7% specificity, and an area under the curve (AUC) of 0.705 to discriminate HCC from cirrhotic groups (P = .002). In multivariate analysis, ordination plot showed obvious demarcation between the study groups caused by the higher levels of TOM34 among other variables. CONCLUSIONS TOM34 and its partner HSP90AA1 might be used as a potential biomarker for monitoring HCV-induced HCC progression in the Egyptian population. Future large-scale validation studies are warranted.

[PMID: 29703790 DOI: 10.1136/gutjnl-2018-316234] [Citation(s) in RCA: 84] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2018] [Revised: 03/15/2018] [Accepted: 04/05/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS Extrahepatic manifestations of HCV are responsible for morbidity and mortality in many chronically infected patients. New, interferon-free antiviral treatment regimens, which present the opportunity to treat all HCV-infected patients, call for a better understanding of the benefits of treating non-cirrhotic chronically infected individuals. METHODS A systematic review was conducted. Identified studies from targeted database searches on Embase and Medline were screened. The methodological quality of the included publications was evaluated. Random-effect model meta-analyses were performed. Strength of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation system. RESULTS Data were extracted from a total of 48 identified studies. Achieving sustained virological response (SVR) was associated with reduced extrahepatic mortality (vs no SVR, OR 0.44 (95% CI 0.28 to 0.67)). SVR was associated with higher complete remissions in patients with cryoglobulinemia vasculitis (OR 20.76 (6.73 to 64.05)) and a higher objective response in those with malignant B-cell lymphoproliferative diseases (OR 6.49 (2.02 to 20.85)). Achieving SVR was also associated with reduced insulin resistance at follow-up (OR 0.42 (0.33 to 0.53)) and a significant protective effect on the incidence of diabetes (OR 0.34 (0.21 to 0.56)). Lack of randomised data comparing SVR versus non-SVR patients for the relevant extrahepatic indications attenuated these analyses. CONCLUSION Antiviral therapy can reduce extrahepatic manifestations related to HCV when SVR is achieved. Higher quality data, and reporting over longer follow-up periods, will be required to thoroughly explore comprehensive HCV treatment strategies.

Abstract
The possible association between Toxoplasma gondii infection and paediatric haematological malignancies in a group of patients and control subjects was evaluated in the present study. We performed an age-, gender- and residence frequency-matched case-control study of 101 blood cancer patients under 18 years of age, all of which were treated in Amirkola Pediatric Hospital. One hundred and thirty-eight control samples were gathered from the outpatient clinic in the hospital. All cases and controls were tested for the presence of anti-Toxoplasma IgG antibodies and then IgG-positive subjects were evaluated for IgM antibodies by enzyme-linked immunoassays. Anti-T. gondii IgG antibodies were found in 37 (36.6%) of the cases and 12 (8.7%) subjects in the control group (odds ratio 6.07, 95% confidence interval 2.963-12.437, P < 0.0001). The median and interquartile range (IQR) of IgG titre from case group (7.7 (IQR 0.25-13.5)) was higher than the control (0.2 (IQR 0.1-0.5)) (P < 0.0001). The frequency of anti-T. gondii antibodies (IgG) in lymphoblastic leukaemia (acute lymphoblastic leukaemia), Hodgkin's lymphoma and T-cell lymphoma were 33 (31.9%), 3 (50%) and 1(100%), respectively. Anti-T. gondii IgM was not detected in the IgG-positive patients in case group. In the case subjects, no significant difference was seen in the positive rates of T. gondii infection between genders (37.3% in male; 35.7% in female; P = 0.52) and ages groups (P = 0.31). This study demonstrated that T. gondii infection is prevalent in children with blood cancer. It also showed that toxoplasmosis may possibly be linked with an increased risk of childhood haematologic malignancies. Furthermore, these results may be helpful in research on blood neoplasia aetiology.

Abstract
Introduction Chronic hepatitis C virus (HCV) infection is one of the leading causes of hepatocellular carcinoma (HCC) worldwide. Antiviral therapy in patients with HCV infection reduces the risk of primary HCC development by 71%–75%. HCV-infected patients with different primary cancers are also at risk for HCC development as a second primary malignancy (HCC-SPM). Limited information is available on the occurrence and characteristics of HCC-SPM. Herein, we determine the prevalence and clinical features of HCV-associated HCC-SPM when compared to primary HCC. Materials and methods Patients with HCV-associated HCC seen at MD Anderson Cancer Center (2011–2017) were enrolled in a prospective observational study. Patients with multiple cancers diagnosed simultaneously or with hepatitis B virus or HIV coinfections were excluded. At enrollment, patients completed a questionnaire on medical history and HCC risk factors. Information on demographics, comorbidities, HCV treatment, tumor characteristics, treatment modalities, and virologic and oncologic outcomes were extracted from the medical records. Results Among 171 consecutive patients with HCV-associated HCC enrolled, 26 (15%) had HCC-SPM. Most of the underlying primary cancers were solid tumors (85%). In 12 (46%) of these patients, the diagnosis was made incidentally while undergoing surveillance for primary malignancies, and the majority (81%) had their primary cancer in remission. Most patients (72%) with documented HCV viral load had chronic viremia due to lack of diagnosis, lack of treatment, or prior unsuccessful treatment of HCV infection and only 28% had undetectable viral load following successful antiviral therapy. The overall median survival for both groups was 29 months (95% CI: 23–35) without difference between groups (p=0.2). Conclusion Cancer patients with any malignancies must be screened for HCV as HCC-SPM can develop in 15% of infected patients. Early HCV diagnosis and treatment should be attempted to prevent the development of HCC-SPM, a condition associated with high mortality in cancer survivors.

Abstract
The incidence rate of hepatocellular carcinoma (HCC) is rising. It is one of the most common cancers worldwide and accounts for substantial morbidity and mortality. Chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and nonalcoholic fatty liver disease (NAFLD) are the most important etiologies of HCC, and effective screening and management strategies are crucial to reduce the HCC risk. For HBV, which accounts for the majority of HCC cases, most infections were acquired via perinatal and early horizontal transmission. Universal vaccination of newborns has led to a decline in HCC incidence compared with the pre-vaccination era. Effective antiviral therapies with nucleos(t)ide analogues or pegylated interferon reduced the incidence of HCC. For HCV, the emergence of effective direct-acting antiviral (DAA) agents has substantially improved cure rates; therefore all patients with HCV should be considered for DAA treatment. The most important obstacle in eliminating HCV is access to therapy. For NAFLD, the global incidence is increasing rapidly, thus its impact on HCC incidence may be explosive. Progression to HCC in NAFLD happens particularly in those with nonalcoholic steatohepatitis (NASH) and exacerbated by metabolic syndrome, or PNPLA3 gene polymorphism. Lifestyle changes are imperative while drug therapy has yet to demonstrate substantive protective effects on HCC prevention. For management of HCC, early diagnosis via imaging surveillance among persons with HCC risk factors remains the most important strategy to identify early-stage disease appropriate for resection or transplantation.

Abstract
Patients who develop chronic fibrotic liver disease, caused by viral or metabolic aetiologies, are at a high risk of developing hepatocellular carcinoma (HCC). Even after complete HCC tumour resection or ablation, the carcinogenic tissue microenvironment in the remnant liver can give rise to recurrent de novo HCC tumours, which progress into incurable, advanced-stage disease in most patients. Thus, early detection and prevention of HCC development is, in principle, the most impactful strategy to improve patient prognosis. However, a "one-size-fits-all" approach to HCC screening for early tumour detection, as recommended by clinical practice guidelines, is utilised in less than 20% of the target population, and the performance of screening modalities, including ultrasound and alpha-fetoprotein, is suboptimal. Furthermore, optimal screening strategies for emerging at-risk patient populations, such as those with chronic hepatitis C after viral cure, or those with non-cirrhotic, non-alcoholic fatty liver disease remain controversial. New HCC biomarkers and imaging modalities may improve the sensitivity and specificity of HCC detection. Clinical and molecular HCC risk scores will enable precise HCC risk prediction followed by tailoured HCC screening of individual patients, maximising cost-effectiveness and optimising allocation of limited medical resources. Several aetiology-specific and generic HCC chemoprevention strategies are evolving. Epidemiological and experimental studies have identified candidate chemoprevention targets and therapies, including statins, anti-diabetic drugs, and selective molecular targeted agents, although their clinical testing has been limited by the lengthy process of cancer development that requires long-term, costly studies. Individual HCC risk prediction is expected to overcome the challenge by enabling personalised chemoprevention, targeting high-risk patients for precision HCC prevention and substantially improving the dismal prognosis of HCC.

Abstract
The elimination of hepatitis C virus (HCV) has been made possible through the availability of new antiviral drugs which may now be administered to all patients with HCV infection, even those with decompensated cirrhosis. The goal of the World Health Organization (WHO) is to reduce the incidence of chronic hepatitis infection from the current 6-10 million to 0.9 million cases of chronic infections by 2030, and annual deaths from 1.4 million to fewer than 0.5 million. Achieving these targets will require full implementation of epidemiological knowledge of HCV infection, screening and testing practices and strategies to link HCV patients to care. This review will focus on the current state of knowledge in the epidemiology of HCV and what can be done to increase patient awareness and reduce the barriers to treatment. Furthermore, we will discuss the role of HCV clearance on the control of HCV-related outcomes.

Abstract
Contemporary information on the fraction of cancers that potentially could be prevented is useful for priority setting in cancer prevention and control. Herein, the authors estimate the proportion and number of invasive cancer cases and deaths, overall (excluding nonmelanoma skin cancers) and for 26 cancer types, in adults aged 30 years and older in the United States in 2014, that were attributable to major, potentially modifiable exposures (cigarette smoking; secondhand smoke; excess body weight; alcohol intake; consumption of red and processed meat; low consumption of fruits/vegetables, dietary fiber, and dietary calcium; physical inactivity; ultraviolet radiation; and 6 cancer-associated infections). The numbers of cancer cases were obtained from the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute; the numbers of deaths were obtained from the CDC; risk factor prevalence estimates were obtained from nationally representative surveys; and associated relative risks of cancer were obtained from published, large-scale pooled analyses or meta-analyses. In the United States in 2014, an estimated 42.0% of all incident cancers (659,640 of 1570,975 cancers, excluding nonmelanoma skin cancers) and 45.1% of cancer deaths (265,150 of 587,521 deaths) were attributable to evaluated risk factors. Cigarette smoking accounted for the highest proportion of cancer cases (19.0%; 298,970 cases) and deaths (28.8%; 169,180 deaths), followed by excess body weight (7.8% and 6.5%, respectively) and alcohol intake (5.6% and 4.0%, respectively). Lung cancer had the highest number of cancers (184,970 cases) and deaths (132,960 deaths) attributable to evaluated risk factors, followed by colorectal cancer (76,910 cases and 28,290 deaths). These results, however, may underestimate the overall proportion of cancers attributable to modifiable factors, because the impact of all established risk factors could not be quantified, and many likely modifiable risk factors are not yet firmly established as causal. Nevertheless, these findings underscore the vast potential for reducing cancer morbidity and mortality through broad and equitable implementation of known preventive measures.

Abstract
UNLABELLED Hepatitis C virus (HCV) reactivation in patients receiving cancer treatment has been reported in retrospective studies. We sought to determine prospectively the incidence, predictors, and clinical significance of HCV reactivation during cancer treatment. HCV-infected patients receiving cancer treatment at our institution between November 2012 and July 2016 were studied. Reactivation was defined as an increase in HCV-RNA ≥1 log10 IU/mL over baseline and hepatitis flare as an increase in alanine aminotransferase to ≥3 times the upper limit of normal. One hundred patients were studied, 50 with hematologic malignancies and 50 with solid tumors. Reactivation occurred in 23 (23%) patients, including 18 (36%) patients with hematologic malignancies and 5 (10%) patients with solid tumors. In univariate analysis, patients with reactivation were more likely than those without reactivation to have prolonged lymphopenia (median, 95 versus 22 days; P = 0.01) and to have received rituximab (44% versus 9%; P < 0.0001), bendamustine (22% versus 0%; P < 0.001), high-dose steroids (57% versus 21%; P = 0.001), or purine analogs (22% versus 5%; P = 0.02). Rituximab (odds ratio = 9.52; P = 0.001), and high-dose steroids (odds ratio = 5.05; P = 0.01) retained significance in multivariable analysis. Of the 23 patients with reactivation, 10 (43%) had hepatitis flare. No patient with reactivation experienced liver failure or liver-related death within 36 weeks after initiation of cancer treatment. Fourteen patients with hepatitis flare, six of whom had reactivation, required discontinuation or dose reduction of cancer treatment. CONCLUSION HCV reactivation occurred in 23% of HCV-infected patients receiving cancer treatment, and most had an unremarkable clinical course. However, reactivation can affect the cancer treatment plan. Our findings suggest that HCV infection should not contraindicate cancer therapy and infected patients should have access to multiple cancer treatments with close monitoring while receiving regimens associated with HCV reactivation.

Cancer 2017; 124:960-965. [PMID: 29149493 DOI: 10.1002/cncr.31146] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Revised: 09/27/2017] [Accepted: 10/02/2017] [Indexed: 12/14/2022]
Abstract
BACKGROUND Although an association between hepatitis C virus (HCV) infection and oropharyngeal cancers (OPCs) has been reported, to the authors' knowledge the clinical significance of this epidemiological finding remains unknown. Therefore, the authors analyzed the oncologic outcomes of HCV-infected patients with OPCs. METHODS In this retrospective cohort study, all patients with OPCs who were seen at The University of Texas MD Anderson Cancer Center between January 2004 and December 2015 were reviewed. HCV infection was defined as detectable HCV RNA in the serum. Five-year overall survival and progression-free survival rates were compared between patients infected with HCV and those not infected. RESULTS A total of 161 patients were examined. The majority of the patients were white (141 patients; 88%) and male (132 patients; 82%) and had TNM stage III or IV disease (147 patients; 91%). The OPC involved the tonsils (83 patients; 52%), base of the tongue (67patients; 42%), or the soft palate (11 patients; 7%). The median follow-up after an OPC diagnosis was 3 years (range, 1-13 years). HCV-infected patients (25 patients) and HCV-uninfected patients (136 patients) were comparable with regard to smoking and alcohol status. In multivariate analysis, HCV was associated with increased cancer-specific mortality (hazard ratio, 2.15; 95% confidence interval, 1.08-6.85 [P = .02]) and risk of OPC progression (hazard ratio, 5.42; 95% confidence interval, 2.64-11.14 [P = .0008]) independent of age and cirrhosis status. Antivirals were administered after the diagnosis of OPC in 8 of the 25 HCV-infected patients (32%). HCV-infected patients who received antivirals were found to have better 5-year overall survival (70% vs 12%; P = .005) and progression-free survival (72% vs 19%; P = .005) compared with patients who did not. CONCLUSIONS The early detection of HCV is important in patients with OPC because this infection may affect their oncologic outcomes. Cancer 2018;124:960-5. © 2017 American Cancer Society.

Abstract
Hepatitis C virus (HCV) causes a chronic but curable infection associated with the development of marginal zone lymphoma (MZL) and diffuse large B-cell lymphoma (DLBCL). Preliminary data have shown frequent transformation of indolent lymphoma to DLBCL in HCV-infected patients. To compare their clinicopathologic characteristics and oncologic outcomes, we reviewed the medical records and pathology reports of HCV-infected and uninfected patients with DLBCL that transformed from indolent lymphoma seen at The University of Texas MD Anderson Cancer Center (June 2004 to May 2015). To identify predictors of DLBCL relapse, patients with relapse after first-line chemotherapy were compared with those without it using univariate and logistic regression analyses. Compared with the uninfected patients (n = 63), HCV-infected patients (n = 21) were younger (median age =54 years [interquartile range= 49-62 years] vs. 62 years [53-66 years]; p = 0.01) and more often had advanced DLBCL (Ann Arbor stage 3-4; 95% vs. 76%; p = 0.05). Immunophenotypically, more HCV-infected than uninfected patients had CD10-negative B cells (76% vs. 43%; p = 0.008), CD5-positive B cells (39% vs. 7%; p = 0.004) and activated B-cell phenotypes (57% vs. 31%; p = 0.07). Comparison of the patients who had relapse after first-line chemotherapy (n = 42) and those who did not (n = 40) revealed that having CD5-positive B cells was the only factor associated with DLBCL relapse in multivariate analysis (odds ratio= 10.7; p = 0.02). HCV-infected patients with transformed DLBCL have unique clinicopathologic characteristics that make their lymphoma difficult to treat, potentially leading to unfavorable outcome. The impact of HCV eradication should be explored in such patients.

Efficacy and prognosis of antiviral therapy on hepatitis C following treatment of lymphoma in HCV-positive diffuse large-cell lymphoma. Ann Hematol 2017; 96:2057-2061. [PMID: 28939993 PMCID: PMC5691112 DOI: 10.1007/s00277-017-3129-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2017] [Accepted: 09/06/2017] [Indexed: 02/06/2023]
Abstract
The purpose of this study is to study the usefulness of post-remission antiviral therapy in cases of HCV-RNA-positive diffuse large-cell lymphoma. Antiviral therapy against HCV was performed after remission using CHOP or CHOP-like chemotherapy in combination with rituximab in five successive cases of HCV-RNA-positive diffuse large-cell lymphoma. The control groups consisted of a group of HCV-RNA-positive diffuse large-cell lymphoma cases prior to this trial (control 1), and a group of cases that tested negative for HIV, HCV, and HBV (control 2). All the cases were in remission at the time of initial treatment. There were no significant differences between the three groups in terms of age, sex, treatment, stage, or International Prognosis Index (IPI). When HCV antiviral therapy was performed after treatment for diffuse large-cell lymphoma, we observed no recurrence or deaths, and the 2-year overall survival and progression-free survival rates were significantly greater than those in the control 1 group (P = 0.0246). It is possible that a better prognosis can be achieved by performing HCV antiviral therapy after achieving remission in cases of HCV-RNA-positive diffuse large-cell lymphoma through the use of R-CHOP or similar treatments.
