Advanced hepatocellular carcinoma with response to lenvatinib after atezolizumab plus bevacizumab

Rationale:Various treatments are available for treating hepatocellular carcinoma (HCC). The immune checkpoint inhibitor combination of atezolizumab plus bevacizumab was recently approved for the treatment of unresectable HCC, but there are few reports on the failure of the combination treatment. Here, we present a case of unresectable HCC with adrenal metastasis that was eventually operated on after lenvatinib (LEN) treatment that followed failed treatment with atezolizumab plus bevacizumab.Patient concerns:A 68-year-old man was diagnosed with non-alcoholic steatohepatitis-based HCC with adrenal metastasis.Diagnosis:Cirrhosis was classified as Child-Pugh score of 5. HCC was diagnosed as Barcelona Clinic Liver Cancer stage C.Interventions:We initiated treatment with atezolizumab plus bevacizumab. Liver dysfunction appeared 2 days after the first administration but was improved by intravenous rehydration and did not appear after the second course. The HCC shrank, but the adrenal metastasis grew bigger after the fourth course, so we changed the therapy to LEN. After HCC and adrenal metastasis were necrotic by LEN, conversion surgery was performed.Outcomes:After successful conversion therapy, the general condition of the patient was good, and has been carefully followed for 4 months to date without any evidence of further recurrences.Lessons:This case showed that even if atezolizumab plus bevacizumab is not effective, multidisciplinary treatment such as LEN and conversion surgery is possible. Given the efficacy of LEN after atezolizumab plus bevacizumab, it is important to consider that there is a possibility of cure even when first-line treatment is not effective for a patient with unresectable HCC.     

Sorafenib in the treatment of hepatocellular carcinoma: a multi-centre real-world study

Objective: Sorafenib is an oral multikinase inhibitor that improves survival in advanced hepatocellular carcinoma (HCC). In the absence of alternative therapies, sorafenib is often continued despite advancing liver disease or tumour progression. Real world studies are important to better characterise outcomes in these populations. Our aim was to review patterns of sorafenib use across eight Australian tertiary hospitals, defining variables associated with clinical outcomes. Material and methods: Retrospective cohort study of medical records of 320 patients treated with sorafenib for HCC. Baseline clinical parameters, dosage, adverse effects, and survival from initiation of treatment were collected. Time to radiological progression and 3-month alpha-fetoprotein (AFP) levels were available for a subset of patients. Results: Adverse effects occurred in 79% of patients, requiring dose reduction in 31% of patients. Multivariate analysis identified an increased rate of mortality with Child-Pugh C (HR 5.52, p?=?0.012), ECOG performance status 2–3 (HR 2.84, p?=?0.001), and extrahepatic metastases (HR 1.54, p?=?0.04), and decreased rate of mortality with an AFP reduction of at least 20% at 3 months (HR 0.38, p?=?0.001). An increased rate of radiological progression was associated with ECOG performance status 2–3 (HR 2.34, p?=?0.041), whilst a decreased rate of radiological progression was associated with development of on-treatment diarrhoea (HR 0.55, p?=?0.015). Conclusions: Survival in patients with Child-Pugh C liver function or advanced functional impairment treated with sorafenib is poor and thus routine use of this agent in these patients does not appear justified, particularly given the high rate of adverse effects. AFP concentration on therapy may help identify favourable response to treatment.     

Tocilizumab for the treatment of immune-related adverse events: a systematic literature review and a multicentre case series

ObjectiveResearch is moving towards a more personalized management of immune-related adverse events (irAEs) due to immune checkpoint inhibitors (ICI). Our objective was to evaluate the efficacy and safety of tocilizumab in the treatment of these clinical manifestations.MethodsA systematic literature review was performed to retrieve data about the use of tocilizumab in the treatment of irAEs. Additionally, data from cancer patients referred to our Immune-related Adverse Event Clinic and treated with tocilizumab were collected.ResultsOur literature review identified 20 articles and 11 meeting abstracts. Data about 91 cancer patients who received tocilizumab for the treatment of irAEs were collected. In 85% of cases, this therapy was associated with clinical benefit and no case of disease progression was reported. ICI therapy was continued following irAE onset and biologic therapy initiation in only three patients.Five patients developed irAEs upon ICI initiation and were subsequently treated with tocilizumab at our Centre. At a median follow-up of eight months, tocilizumab was safely continued along with ICI in three out of five patients, and an adequate control of irAE was obtained in all cases. No significant adverse reactions to tocilizumab were reported. Only one patient experienced a disease progression 18 months after ICI discontinuation.ConclusionBoth our systematic literature review and case series highlight the efficacy and safety of tocilizumab in the treatment of irAEs. Furthermore, they both support the possibility of a combined approach with tocilizumab and ICI, to guarantee an effective irAEs management without losing the oncologic response.     

Safety and efficacy of pomalidomide,dexamethasone and pegylated liposomal doxorubicin for patients with relapsed or refractory multiple myeloma

Immunomodulatory drugs including thalidomide, lenalidomide (LEN) and pomalidomide (POM), are effective for treating multiple myeloma (MM). POM has shown enhanced efficacy with dexamethasone (DEX). Pegylated liposomal doxorubicin (PLD) with bortezomib is US Food and Drug Administration‐approved for treating MM. PLD with LEN or thalidomide has shown efficacy for MM patients. LEN with DEX, PLD and bortezomib achieves high response rates. We evaluated the combination of POM with DEX 40 mg and PLD 5 mg/m² with the latter two drugs administered on days 1, 4, 8 and 11 on a 28‐day cycle for the treatment of relapsed/refractory MM patients. During Phase 1, the maximum tolerated dose of POM was 4 mg, and was used in Phase 2, which also required patients to be refractory to LEN. However, neutropenia ≥ grade 3 was observed in 10/17 (59%) patients, and the dose was lowered to 3 mg. Median PFS was 5·4 months (range, 0·3–29·0 +  months). Overall response rates for patients in Phase 2 were 39% and 31% among subjects receiving POM at 3 mg and 4 mg, respectively, and clinical benefit rates were 51% and 44%, respectively. POM, PLD and DEX is a treatment option for relapsed/refractory MM patients including those who are refractory to LEN.     

Predictors and outcome of emergent Liver transplantation for patients with acute-on-chronic liver failure

Background and aimsControversy exists over whether emergent liver transplantation (LT) should be performed for patients with acute-on-chronic liver failure (ACLF), especially for patients with multiple organ failure.MethodsA total of 110 ACLF patients, defined by the European Association for the Study of the Liver (EASL) Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) criteria were analyzed. The primary outcome was overall survival after ACLF diagnosis.ResultsDuring follow-up, 76 patients received LT (59 received deceased-donor LT and 17 patients received living-donor LT). The overall survival was better for patients who received LT than patients who did not (82.9% vs. 17.6%, P < 0.001). Among the 76 patients who received LT, the overall survival was not different according to ACLF grade at diagnosis (70.0%, 85.3%, and 84.4% at one-year for ACLF grades 1, 2, and 3, respectively, P = 0.45). The baseline model for end-stage liver disease (MELD) score and progression of the ACLF grade during the pre-transplant period were independent factors for survival after LT. The one-year survival rate was 92.3% for patients with baseline MELD scores of ≤ 32 without ACLF grade progression, whereas it was 33.3% for those with baseline MELD scores of > 32 and ACLF grade progression.ConclusionsEmergent LT provided a significant survival benefit to ACLF patients, regardless of the baseline ACLF grade. Post-LT outcomes were associated with baseline MELD scores and ACLF progression during the pre-transplant period, which might be used in the emergent LT plan for patients presenting with ACLF.     

Nanoliposomal irinotecan (Nal-IRI)-based chemotherapy after irinotecan -based chemotherapy in patients with pancreas cancer

BackgroundNanoliposomal irinotecan (Nal-IRI) is a preferred second-line treatment for metastatic pancreas cancer. It is unclear, however, whether patients who had received irinotecan derive benefit.MethodsMedical records of metastatic pancreas cancer patients who had received irinotecan and then Nal-IRI were reviewed. The primary endpoint was overall survival after the initiation of Nal-IRI (an a priori threshold of >4 months defined success); adverse events and quotes from the medical record on decision-making were also recorded.ResultsSixty four patients met eligibility criteria with a median age of 65 years (range: 36, 80 years). The median overall survival from initiation of Nal-IRI was 5.1 months (95% confidence interval (CI): 4.3, 5.6 months). An exploratory comparison, based on no cancer progression with irinotecan versus progression, showed improved survival with Nal-IRI in the former group: 6.1 months (95% CI: 5.1, 9.3 months) versus 4.3 months (95% CI: 2.3, 4.8 months); p = 0.0006. Nal-IRI adverse events occurred as expected. Qualitative data illustrate several themes, including “limited treatment options,” which appeared to drive the decision to prescribe Nal-IRI.ConclusionNal-IRI might be considered in pancreas cancer patients who had received irinotecan, particularly in the absence of disease progression with the latter.     

Evaluating bevacizumab in combination with FOLFIRI after the failure of platinum-etoposide regimen in patients with advanced poorly differentiated neuroendocrine carcinoma: The PRODIGE 41–BEVANEC randomized phase II study

IntroductionPatients with gastroenteropancreatic (GEP), metastatic or locally advanced, non-resectable, grade 3 poorly-differentiated neuroendocrine carcinoma (NEC) are treated with cisplatin (or carboplatin)-etoposide in first-line palliative chemotherapy (CT1). However, nearly all patients will develop resistance and there is no standard second-line treatment.AimPRODIGE 41–BEVANEC is an academic randomized, phase II study designed to evaluate the efficacy of bevacizumab in combination with FOLFIRI after failure of CT1 in unknown primary NEC and GEP-NEC.Materials and methodsThe main eligibility criteria are age ≥18 years, metastatic (synchronous or metachronous) or locally advanced, non-resectable, grade 3 GEP-NEC, and documented progressive disease during or after CT1 therapy.ResultsA total of 124 patients will be randomly assigned (1:1) to receive either 5 mg/kg bevacizumab with FOLFIRI, or FOLFIRI alone, every 14 days until disease progression or unacceptable toxicity. The hypothesis is to demonstrate a 6-month overall survival for at least 50% of the patients in bevacizumab arm versus 35% in the control arm (FOLFIRI alone). Secondary endpoints are objective response, response duration, progression-free survival, toxicity, and biochemical response.ConclusionThe study is currently opened in France (NCT02820857). The first patient was randomized on September 6, 2017.     

Everolimus treatment for patients with autoimmune hepatitis and poor response to standard therapy and drug alternatives in use

Abstract

Objective. Not all patients with autoimmune hepatitis (AIH) respond to standard medical therapy with corticosteroids and azathioprine. Such patients may develop end-stage liver disease with poor prognosis unless transplantation is considered. Alternatively, the introduction of new therapeutic strategies could potentially ameliorate deterioration of liver function. Patients in our tertiary center were selected for everolimus therapy when exhibiting nonresponse or intolerance to combinations of the standard and empirical drugs in use (e.g., mycophenolate mofetil, calcineurin inhibitors [CNIs]). We here report the efficacy of everolimus treatment of patients with AIH. Materials and methods. Seven patients (six female, mean age 47 years, range 22–62 years) in whom disease control could not be achieved with standard therapy or the alternative drugs in use were included. Results. Treatment with everolimus induced a clear reduction of transaminases within 2 weeks. After 3–5 months three patients had normal alanine aminotransferase (ALT) levels (10–45 IU) and four patients had ALT levels below 55 IU compared to a three- to fivefold elevated level prior to everolimus treatment. Sustained remission after 1 year of treatment was observed in three patients; in another two patients ALT was 45–68 U/L. Four patients in remission after 3 years were rebiopsied. Two showed no histological progression, and in two the fibrosis had decreased. Side effects noted were myalgias and minor bacterial infections not leading to discontinuation of the drug. Conclusion. Our experience indicates that everolimus may be of value in selected patients with therapy-resistant AIH and comorbidity/side effects that excludes the use of CNIs.     

Effect of topical immunotherapy with squaric acid dibutylester for alopecia areata in Japanese patients

BackgroundThe Japanese guidelines for the treatment of alopecia areata list topical immunotherapies as a drug therapy for this condition. However, there is insufficient evidence of its efficacy to support this recommendation. Thus, we sought to clarify the effect of topical immunotherapy on the progression and severity of alopecia areata in Japanese patients.MethodsTo evaluate the effect of topical immunotherapy with squaric acid dibutylester (SADBE) in alopecia areata patients, we performed a retrospective cohort study on 49 alopecia patients who had received topical immunotherapy with SADBE. Patients were evaluated by the change in alopecia severity at 6 and 12 months after the initiation of topical immunotherapy. The improvement rate was calculated by determination of the complete and partial responses rate to treatment with topical immunotherapy by application of SADBE.ResultsThe improvement rate in all alopecia patients treated with SADBE topical immunotherapy was 57.8% (complete response; 11.1% and partial response; 46.7%).ConclusionsTopical immunotherapy with SADBE is an effective treatment for alopecia areata. Therefore, the current treatment recommendations for alopecia areata with topical immunotherapies are appropriate.     

Outcomes for Cirrhotic Patients with Hepatitis C Virus 1b Treated with Asunaprevir and Daclatasvir Combination

BackgroundThe efficacy and safety of asunaprevir + daclatasvir combination therapy for treatment of hepatitis C virus (HCV) in compensated cirrhotic patients was not fully evaluated in real-world. Outcomes were assessed in cirrhotic patients with sustained viral response (SVR).Material and methodsA total of 145 patients without resistance-associated substitutions (RASs) at L31 and Y93 in the nonstructural protein 5A of HCV genotype 1b, consisting of 49 hepatic cirrhotic and 96 non-cirrhotic patients, were enrolled to the therapy. The patients were treated with 100 mg asunaprevir twice daily plus 60 mg daclatasvir once daily for 24 weeks. The primary endpoint was SVR 24 weeks after completing treatment. In addition, we evaluated the improvement of liver function and development of HCC for 1 year from the end of treatment (EOT).ResultsThe SVR24 rate was 96% (47/49) in the cirrhotic group and 96% (91/95) in the non-cirrhotic group (p = 0.69). During treatment, grade III/IV adverse events occurred more frequently in cir-rhotic patients (10/49; 20.4%) than in non-cirrhotic patients (10/96; 10.4%) (p = 0.099). After EOT, alanine aminotransferase and AFP levels were significantly decreased in cirrhotic patients with SVR. In addition, serum levels of albumin and platelet counts were significantly increased. On the other hand, the rates of HCC recurrence (43%) and development (7.4%) were higher in cirrhotic patients than in the non-cirrhotic patients (12.5% and 1.1%, respectively).ConclusionRAS-oriented asunaprevir/daclatasvir therapy has a strong anti-HCV effect in patients with HCV genotype 1b. However, careful management is necessary in patients with cirrhosis.     

Evaluating lanreotide as maintenance therapy after first-line treatment in patients with non-resectable duodeno-pancreatic neuroendocrine tumours

IntroductionPatients with metastatic or locally advanced, non-resectable, grade 1 or 2 well-differentiated duodeno-pancreatic (WDDP) NETs are treated following European guidelines. Patients (Pts) with aggressive disease, i.e. progressive and/or symptomatic metastases and/or with significant hepatic invasion (>30–50%), and/or bone metastases, anti-tumour therapy should receive systemic combination of chemotherapy once disease control is obtained.Aim(s)The aim is to stop chemotherapy until progression. REMINET is an academic randomized, double-blind, placebo-controlled, phase II/III study designed to evaluate lanreotide (LAN) as maintenance treatment after L1 chemotherapy in G1-G2 WDDP NET.Materials and methodsMain eligibility criteria: adults pts with a metastatic (synchronous or metachronous) or locally advanced, non-resectable, grade 1 or 2 WDDP NETs and documented control disease after L1 therapy at least 4 weeks prior to randomization.Results222 patients will be randomly assigned in a 1:1 ratio to receive 120 mg LAN or placebo, every 28 days, until disease progression or unacceptable toxicity. The aim of the phase II part is to demonstrate a 6-months PFS >45% in LAN arm. Secondary endpoints are PFS according to central review, overall survival, safety and quality of life. A bio-bank of frozen blood will be constituted.ConclusionThe study is currently open in France, Germany, Belgium, United Kingdom and Ireland. A total of 25 patients are randomized (NCT02288377).     

Efficacy and safety of pemetrexed maintenance chemotherapy for advanced non-small cell lung cancer in a real-world setting

BackgroundPemetrexed maintenance therapy offers a survival benefit in patients with nonprogressive advanced nonsquamous non-small cell lung cancer (NSCLC) with good tolerability. This study was designed to analyze the efficacy and safety of pemetrexed maintenance chemotherapy in advanced nonsquamous NSCLC patients in a real-world setting.MethodsThe response rate (RR) and adverse events in 71 nonsquamous NSCLC patients treated with pemetrexed-based chemotherapy were observed until disease progression or unacceptable toxicities. Measures of survival were analyzed during follow-up.ResultsOf 69 efficacy-evaluable patients, the objective response rate (ORR) was 46.4% and the disease control rate (DCR) was 98.6%. ORR showed no significant difference between patients who received pemetrexed as first-line therapy and those who received pemetrexed as second-line or higher treatment. The median treatment cycle for all patients was 8. The median progression-free survival (PFS) was 9.5 months (m) and median overall survival (OS) was 30.5 m. The univariate and multivariate analyses showed that the number of chemotherapy cycles was an independent factor for PFS. The most common adverse reactions were grade 1 to 2 hematologic toxicities, gastrointestinal reactions, and liver enzyme abnormalities. Only 1 patient experienced a grade 3 gastrointestinal event.ConclusionsPemetrexed maintenance chemotherapy can improve PFS in patients with advanced nonsquamous NSCLC with good tolerability.     

Propranolol for infantile hepatic hemangioendothelioma: Clinical evaluation of drug efficacy and safety using a single-center patient cohort

Introduction and objectivesInfantile hepatic hemangioendothelioma (IHHE) is a benign liver tumor, associated with hypothyroidism and vascular malformations along the skin, brain, digestive tract and other organs. Here, we determined a single-center patient cohort by evaluating the effectiveness and safety of propranolol and sirolimus for the treatment of IHHE.Patients and methodsWe performed a monocentric and observational study, based on clinical data obtained from 20 cases of IHHE treated with oral propranolol and sirolimus at the Shanghai Children's Medical Center (SCMC), between December 2017 and April 2019. All cases were confirmed by abdominal enhanced CT examination (18/20, 90%) and sustained decrease of alpha fetoprotein (AFP) (2/20, 10%).Propranolol treatment was standardized as once a day at 1.0 mg/kg for patients younger than 2 months, and twice a day at 1.0 mg/kg (per dose) for patients older than 2 months. Sirolimus was used to treat refractory IHHE patients after 6 months of propranolol treatment, and initial dosing was at 0.8 mg/m² body surface per dose, administered every 12 h. Upon treatment, abdominal ultrasound scanning was regularly performed to evaluate any therapeutic effects. All children were followed up for 6–22 months (mean value of 12.75 months). The clinical manifestations and therapeutic effects, including complications during drug management, were reviewed after periodic follow-up.ResultsThe effective rate of propranolol for the treatment of children with IHHE was 85% (17/20). In most cases, the AFP levels gradually decreased into the normal range. A complete response (CR) was achieved in 3 cases, partial response (PR) for 14 cases, progressive disease (PD) for 2 cases and stable disease (SD) was only detected once. Lesions decreased in two PD patients after administration of oral sirolimus. No serious adverse reactions were observed.ConclusionThis study indicates that both propranolol and sirolimus were effective drugs for the treatment of children with IHHE at SCMC.     

Feasibility and therapeutic potential of the 68Ga/177Lu-DOTATATE theranostic pair in patients with metastatic medullary thyroid carcinoma

BackgroundThis study assessed: 1) the clinical efficacy of imaging with 68Ga-DOTATATE PET/CT (SSTR (somatostatin receptor)-PET) to detect medullary thyroid carcinoma (MTC); and 2) the therapeutic efficacy of peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATATE in MTC patients.Materials and methodsPatients with histologically proven MTC and suspected recurrence following thyroidectomy, based on raised serum calcitonin levels, underwent SSTR-PET. In addition, to evaluate the clinical efficacy and safety of PRRT, the patients with intense uptake on SSTR-PET or 99mTc-octreotide scintigraphy underwent PRRT. The Common Terminology Criteria for Adverse Events (version 4.03) was used to grade adverse events after PRRT. Treatment response was classified as complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD).ResultsTwenty MTC patients (10 male, 10 female) with a median age of 48.5 years underwent SSTR-PET. SSTR-PET was positive in 17/20 patients (85%). Four of the 17 patients with positive SSTR-PET were scheduled for PRRT. In addition, 2 patients had positive 99mTc-octreotide scintigraphy results (Krenning score ≥ 2) and were scheduled for PRRT. Two of the 6 patients who underwent PRRT showed PR, 2 SD and 2 PD. Two patients died during the follow-up period. Median overall survival was 19 months (95% CI: 5.52–29.48). There were no cases of significant toxicity.ConclusionRadiolabeled somatostatin analogs are contributive for the management of recurrent MTC. 68Ga-DOTATAE PET-CT showed a relatively high detection rate in recurrent MTC. In addition, PRRT with 177Lu-DOTATATE was found to be a safe alternative therapeutic option for MTC.     

Efficacy of blonanserin transdermal patch on terminal delirium in patients with respiratory diseases

BackgroundDelirium is a common distressing symptom observed in patients with terminal respiratory diseases and is treated with antipsychotic medications such as haloperidol. Its management is difficult, especially in palliative home care, because its administration is limited to oral or injection methods. Recently, the blonanserin transdermal patch was developed as the first antipsychotic percutaneous agent. After it became available, we recognized its potential for the management of delirium and the alleviation of uncontrolled dyspnea in clinical practice. Thus, this study aimed to assess its efficacy in patients with terminal respiratory diseases.MethodsThis retrospective study included 113 patients with respiratory diseases who were cared for at home. The efficacy was evaluated through the prevalence of terminal delirium before and after its treatment initiation for uncontrolled dyspnea.ResultsBlonanserin transdermal patch treatment for uncontrolled dyspnea improved the prevalence and severity of terminal delirium (from 70.4% to 16.3%, p < 0.001) and reduced the number of doctors' visits to patients’ homes within a week before their death (from 4.0 to 3.0, p = 0.086). A sub-group analysis of 23 patients with interstitial pneumonia revealed that the treatment prevented dyspnea progression by inhibiting terminal delirium.ConclusionsBlonanserin transdermal patch performed similarly to haloperidol, as previously reported, for managing terminal delirium. Our study suggests that a blonanserin transdermal patch potentially prevents terminal delirium and alleviates uncontrolled dyspnea in patients with respiratory diseases. Our findings encourage clinical trials to evaluate the safety and efficacy of blonanserin transdermal patches for patients with terminal illnesses.     

Effectiveness of swapping to ustekinumab after vedolizumab failure in patients with multi-refractory Crohn's disease

BackgroundUstekinumab (UST) and vedolizumab (VDZ) are biologic therapies for moderate-to-severe Crohn's disease (CD) in patients who failed or had contraindication to anti-TNF treatment.AimsTo evaluate ustekinumab efficacy as third-line treatment after swapping from VDZ for failure.MethodsWe conducted a monocentric, retrospective, observational study where CD patients were followed for 12 months from the beginning of UST therapy.We assessed clinical activity (HBI) and laboratory markers (CRP) at the initiation of UST therapy (T0) and after 2(T2), 6(T6) and 12(T12) months. Endoscopic activity was recorded at T0 and T12. We registered data regarding their clinical history and previous biologic treatments. Steroid-free clinical remission was defined as HBI ≤ 4 without need for steroids. Clinical response was defined as HBI reduction of at least three points or the suspension of steroids.Results27 CD patients treated with UST after VDZ failure had a minimum follow up of 12 months and were included. All patients had previously been treated with anti-TNF agents. After 12 months, steroid-free clinical remission was evident in 15 (55.5%) patients, 5 (18.5%) had clinical response, while 7 (26%) had suspended for failure or persisted on treatment after optimization.ConclusionsUstekinumab should be considered as third-line biologic treatment in multi-refractory CD patients.     

A phase II study of capecitabine plus oxaliplatin (XELOX): a new first-line option in metastatic colorectal cancer

Background: Capecitabine and oxaliplatin are both effective and well-tolerated monotherapies for the treatment of advanced colorectal cancer (CRC). Oxaliplatin has also been shown to be very effective when combined with 5-FU/LV in the first-line setting. Aim of the Study: Assess the efficacy and safety of capecitabine plus oxaliplatin (XELOX) in patients with previously untreated advanced CRC. Methods: Fifty-three patients with measurable disease received capecitabine 1,000 mg/m² twice daily on d 1–14 and oxaliplatin 130 mg/m² on d 1, every 3 wk. Of these, 52 were evaluable for safety and 49 for antitumor response. Results: There was a low rate of grade 1/2 adverse events; grade 3/4 events included leukopenia (10%), neutropenia (6%), thrombocytopenia (2%), nausea/vomiting (4%), and diarrhea (4%). The overall response rate was 39% (95% CI, 25–54%) and median time to disease progression was 7.8 mo. Conclusions: XELOX is an active and well-tolerated first-line treatment for advanced CRC. Randomized phase III studies are ongoing to compare XELOX with FOLFOX in view of the comparable efficacy and safety but superior convenience of XELOX therapy. Presented in part at the 39th American Society of Clinical Oncology Annual Meeting, Chicago, IL, May 31–June 3, 2003.     

Favorable response to second-line atezolizumab and bevacizumab following progression on nivolumab in advanced hepatocellular carcinoma: A case report demonstrating that anti-VEGF therapy overcomes resistance to checkpoint inhibition

Rationale:Advanced hepatocellular carcinoma (HCC) remains a deadly disease in part due to decades of limited therapeutic options. With recent advances in our understanding of the tumor biology, several promising treatment strategies involving targeted and immunotherapies have emerged. However, enhancing their modest efficacy in HCC and other gastrointestinal malignancies is essential to improving survival.Patient concerns:A man in his late 50s with a history of type 2 diabetes mellitus and morbid obesity initially presented with progressive abdominal pain and anorexia prompting an abdominal computed tomography scan that revealed a large solitary liver mass with extensive local involvement.Diagnoses:Although there were features consistent with a primary gastric tumor on subsequent endoscopic evaluation leading to early diagnostic uncertainty, his clinical picture, including a dominant liver mass, immunohistochemical staining profile, and significantly elevated alpha fetoprotein ultimately favored HCC.Interventions:The patient received palliative systemic therapy with infusional fluorouracil for a presumed gastric primary, however restaging scans after 3 cycles demonstrated disease progression. The consensus from a multidisciplinary discussion was that his pathology was more consistent with primary HCC. He was subsequently started on nivolumab with a partial response, although after 5 months, he progressed prompting initiation of second-line atezolizumab and bevacizumab with a favorable response.Outcomes:The addition of atezolizumab and bevacizumab led to a sustained biochemical and radiographic response that appeared to overcome the resistance to nivolumab monotherapy. Aside from several mild immune-related adverse effects, his quality of life has greatly improved and he has tolerated treatment well to date.Lessons:Our findings suggest that vascular endothelial growth factor inhibition can overcome resistance to checkpoint inhibition in advanced HCC by resulting in a unique synergy that has never before been described in patients. The biological rationale for this response is likely attributable to the immunomodulatory effects of antiangiogenic agents, promoting an immunostimulatory microenvironment that can be exploited by immune checkpoint inhibitors for more effective antitumor activity. Given the considerable benefit patients may derive following progression on first-line treatment, it is important to consider this strategic combination of therapies which can ultimately lead to improved patient outcomes.     

Phase II trial of perillyl alcohol in patients with metastatic colorectal cancer

Purpose. This is a phase II study of perillyl alcohol in the treatment of patients with metastatic colorectal carcinoma. The primary endpoint is time to progression. Secondary objectives are to evaluate objective response rate and toxicity. Patients and Methods. Eligible patients had metastatic adenocarcinoma of the colon or rectum. Patients received perillyl alcohol orally at a dose of 1200 mg/m². Dose escalation to 1,600mg/m² was allowed. Results. Twenty-seven patients were enrolled. The median time to progression was 1.8 months (range 1 to 3 mo). Four patients received less than one cycle and were not evaluable for response. Of the remaining 23, all had progressive disease. There were no complete or partial responses. Toxicity was relatively mild, with fatigue, nausea and anemia predominating. Three patients withdrew from therapy for toxicity (grade 3 belching, bloating; grade 2 nausea, fatigue, vomiting, anorexia and increase perspiration; grade 1 anorexia). Discussion. Despite preclinical evidence of anticancer activity, oral perillyl alcohol administered at this dose and formulation does not appear to have clinical antitumor activity when used for patients with advanced colorectal carcinoma.     

Outcomes of treatment with sorafenib in Egyptian patients with hepatocellular carcinoma: a retrospective cohort study

Background: Sorafenib is the standard of care, first line treatment for advanced HCC. This study aims to evaluate real-life efficacy and safety of sorafenib in Egyptian patients with Hepatocellular carcinoma (HCC).

Methods: This retrospective cohort study was conducted in the medical oncology department at Maadi Armed Forces Medical Compound. Patients with advanced HCC who received sorafenib between January and December 2015 were included (130 patients).

Results: The median overall survival of patients with HCC treated with sorafenib was 5 months (CI: 4.166–5.834), and progression free survival was 4 months (CI: 3.479–4.521). Disease control rate was 45.44% with 2 patients experiencing complete remission (1.2%). The adverse events rate was 76.1% for toxicities of all grades; with hand and foot syndrome being the most common (32.3% of any grade) and liver dysfunction the most common grade III toxicity (13.8%). Treatment was stopped for radiological progression based on modified RECIST criteria in 47 patients (36.3%), 18 patients stopped the treatment for intolerable toxicity. At the end of treatment upon radiological progression, 51 patients (39.2%) were still classified as Child A class of cirrhosis.

Conclusion: Sorafenib use should be limited to patients with Child A, PS 0–1, and low disease burden.
