Advancements in second-line treatment research for hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors, characterized by high incidence and mortality rates. Due to its insidious onset, most patients are diagnosed at an advanced stage, often missing the opportunity for surgical resection. Consequently, systemic treatments play a pivotal role. In recent years, an increasing number of drugs have been approved for first-line systemic treatment of HCC. However, their efficacy is limited, and some patients develop drug resistance after a period of treatment. For such patients, there is currently a lack of standard second-line systemic treatment options. This review summarizes the latest advancements in second-line systemic treatment research for HCC patients who have developed resistance to various first-line systemic treatments, aiming to provide more rational and personalized second-line treatment strategies.

Efficacy and safety of anlotinib plus anti-PD-1 agents in patients with refractory advanced biliary tract cancers.

BACKGROUND: Anlotinib has demonstrated promising anti-tumor efficacy in various solid tumors. Additionally, there is evidence suggesting that immune therapy can enhance the systemic responses of anlotinib. This study aimed to assess the effectiveness and safety of combining anlotinib with PD-1 inhibitors compared to fluoropyrimidine-based chemotherapy as a second-line treatment option for advanced biliary tract cancers (BTCs). METHODS: A total of 242 patients with BTCs were screened at the First Affiliated Hospital of Zhengzhou University from October 2015 to October 2022. Among them, 78 patients who received either anlotinib plus PD-1 inhibitors (AP) or fluoropyrimidine-based chemotherapy (FB) as second-line treatment were included in the study. The primary endpoint was progression-free survival (PFS), and the secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS), safety, and predictive tumor biomarkers. RESULTS: Among the 78 patients with BTCs, 39 patients received AP, while 39 patients were administered FB. The ORR in the AP group was 20.5%, compared to 5.1% in the FB group. The DCR was 87.2% in the AP group and 66.7% in the FB group. The AP group demonstrated significantly better ORR and DCR compared to the FB group (p = 0.042, p = 0.032). The median PFS and OS in the AP group were 7.9 months (95% CI: 4.35-11.45) and 13.9 months (95% CI: 5.39-22.41), respectively. In the FB group, the median PFS and OS were 4.1 months (95% CI: 3.17-5.03) and 13.2 months (95% CI: 8.72-17.68), respectively. The AP group exhibited significantly better median PFS than the FB group (p = 0.027). In the subgroup analysis, patients without liver metastasis had a much longer PFS in the AP group compared to the FB group (14.3 vs. 5.5 months, p = 0.016). Similarly, patients with CEA ≤ 5 µg/L also demonstrated a longer PFS in the AP group compared to the FB group (8.7 vs. 3.9 months, p = 0.008). CONCLUSIONS: The combination of anlotinib and PD-1 inhibitors demonstrated a promising clinical effect compared to fluoropyrimidine-based chemotherapy in the second-line treatment of refractory advanced BTCs. Liver metastases and CEA levels may serve as predictive factors for identifying patients who may benefit from AP therapy.

Efficacy of second and third lines of treatment in advanced soft tissue sarcomas: a real-world study.

BACKGROUND: Soft tissue sarcomas (STSs) are an uncommon and heterogeneous group of tumours. Several drugs and combinations have been used in clinical practice as second-line (2L) and third-line (3L) treatment. The growth modulation index (GMI) has previously been used as an exploratory efficacy endpoint of drug activity and represents an intra-patient comparison. METHODS: We performed a real-world retrospective study including all patients with advanced STS who had received at least 2 different lines of treatment for advanced disease between 2010 and 2020 at a single institution. The objective was to study the efficacy of both 2L and 3L treatments, analysing the time to progression (TTP) and the GMI (defined as the ratio of TTP between 2 consecutive lines of therapy). RESULTS: Eighty-one patients were included. The median TTP after 2L and 3L treatment was 3.16 and 3.06 months, and the median GMI was 0.81 and 0.74, respectively. The regimens most frequently used in both treatments were trabectedin, gemcitabine-dacarbazine, gemcitabine-docetaxel, pazopanib and ifosfamide. The median TTP by each of these regimens was 2.80, 2.23, 2.83, 4.10, and 5.00 months, and the median GMI was 0.78, 0.73, 0.67, 1.08, and 0.94, respectively. In terms of histotype, we highlight the activity (GMI > 1.33) of gemcitabine-dacarbazine in undifferentiated pleomorphic sarcoma (UPS) and in leiomyosarcoma, pazopanib in UPS, and ifosfamide in synovial sarcoma. CONCLUSIONS: In our cohort, regimens commonly used after first-line STS treatment showed only slight differences in efficacy, although we found significant activity of specific regimens by histotype.

Maintenance of angiogenesis inhibition with aflibercept after progression to bevacizumab in metastatic colorectal cancer: real life study in the Valencian community.

INTRODUCTION: The second-line chemotherapy in metastatic colorectal cancer (mCRC) with FOLFIRI-aflibercept demonstrated an increase in survival compared with FOLFIRI in patients previously treated with oxaliplatin-based regimens. Few data are available in patients treated previously with bevacizumab. Our objective is to evaluate the efficacy and safety of FOLFIRI-aflibercept in second-line treatment in patients who have previously received bevacizumab. PATIENTS AND METHODS: This is a observational, retrospective study of patients with mCRC treated with FOLFIRI-aflibercept in 2nd line in eight hospitals in the Valencian Community. Survival, response, and toxicity were analyzed. RESULTS: 122 patients with a median age of 61 years were included. 89% of patients had PS 0-1. The median of PFS (progression free survival) and OS (overall survival) was 5.45 (95% CI 4.74-6.15 months) and 10.15 (95% CI 7.47-12.82 months), respectively. Disease control rate 59.8%. The most common grade 3-4 adverse events were neutropenia (13,1%) and asthenia (9%). The presence of hypertension during treatment with FOLFIRI-aflibercept was associated with a survival benefit. Median of OS was 14.45 (95% CI 11.58-17.32) in patients with hypertension vs 7.78 (95% CI 5.02-10.54) in patients without hypertension (p = .001). Our results suggest that the presence of PS 0, primary tumor surgery, metachronous metastases, and the presence of only 1 metastatic location, are favorable prognostic factors associated with better OS. CONCLUSIONS: Our results confirm the value of maintaining angiogenesis inhibition with FOLFIRI-aflibercept in mCRC after progression to a first-line treatment with bevacizumab. The development of hypertension during treatment is a possible predictive marker of response.

Response to Ursodeoxycholic Acid May Be Assessed Earlier to Allow Second-Line Therapy in Patients with Unresponsive Primary Biliary Cholangitis.

BACKGROUND: Response to ursodeoxycholic acid (UDCA) in primary biliary cholangitis (PBC) has been traditionally assessed 1 to 2 years after treatment initiation. With the development of new drugs, some patients may benefit from an earlier introduction of second-line therapies. AIMS: This study aims to identify whether well-validated response criteria could correctly identify individuals likely to benefit from add-on second-line therapy at 6 months. METHODS: Analysis of a multicenter retrospective cohort which included only patients with clear-cut PBC. RESULTS: 206 patients with PBC (96.6% women; mean age 54 ± 12 years) were included. Kappa concordance was substantial for Toronto (0.67), Rotterdam (0.65), Paris 1 (0.63) and 2 (0.63) criteria at 6 and 12 months, whereas Barcelona (0.47) and POISE trial (0.59) criteria exhibited moderate agreement. Non-response rates to UDCA was not statistically different when assessed either at 6 or 12 months using Toronto, Rotterdam or Paris 2 criteria. Those differences were even smaller or absent in those subjects with advanced PBC. Mean baseline alkaline phosphatase was 2.73 ± 1.95 times the upper limit of normal (× ULN) among responders versus 5.05 ± 3.08 × ULN in non-responders (p < 0.001). CONCLUSIONS: After 6 months of treatment with UDCA, the absence of response by different criteria could properly identify patients who could benefit from early addition of second-line therapies, especially in patients with advanced disease or high baseline liver enzymes levels.

GenoType MTBDRsl for detection of second-line drugs and ethambutol resistance in multidrug-resistant Mycobacterium tuberculosis isolates at a high-throughput laboratory.

We assessed the performance of MTBDRsl for detection of resistance to fluoroquinolones, aminoglycosides/cyclic peptides, and ethambutol compared to BACTEC MGIT 960 by subjecting simultaneously to both tests 385 phenotypically multidrug-resistant-Mycobacterium tuberculosis isolates from Sao Paulo, Brazil. Discordances were resolved by Sanger sequencing. MTBDRsl correctly detected 99.7% of the multidrug-resistant isolates, 87.8% of the pre-XDR, and 73.9% of the XDR. The assay showed sensitivity of 86.4%, 100%, 85.2% and 76.4% for fluoroquinolones, amikacin/kanamycin, capreomycin and ethambutol, respectively. Specificity was 100% for fluoroquinolones and aminoglycosides/cyclic peptides, and 93.6% for ethambutol. Most fluoroquinolone-discordances were due to mutations in genome regions not targeted by the MTBDRsl v. 1.0: gyrA_H70R and gyrB_R446C, D461N, D449V, and N488D. Capreomycin-resistant isolates with wild-type rrs results on MTBDRsl presented tlyA mutations. MTBDRsl presented good performance for detecting resistance to second-line drugs and ethambutol in clinical isolates. In our setting, multidrug-resistant. isolates presented mutations not targeted by the molecular assay.

Randomized phase II trial of FOLFIRI-panitumumab compared with FOLFIRI alone in patients with RAS wild-type circulating tumor DNA metastatic colorectal cancer beyond progression to first-line FOLFOX-panitumumab: the BEYOND study (GEMCAD 17-01).

PURPOSE: Panitumumab plus FOLFOX (P-FOLFOX) is standard first-line treatment for RAS wild-type (WT) metastatic colorectal cancer. The value of panitumumab rechallenge is currently unknown. We assessed addition of panitumumab to FOLFIRI (P-FOLFIRI) beyond progression to P-FOLFOX in patients with no RAS mutations in liquid biopsy (LB). METHODS: In this randomized phase II trial, patients were assigned (3:2 ratio) to second-line P-FOLFIRI (arm A) or FOLFIRI alone (arm B). LB for circulating tumor DNA analysis was collected at study entry and at disease progression. Primary endpoint was 6-month progression-free survival. Two-stage Simon design required 85 patients to be included (EudraCT 2017-004519-38). RESULTS: Between February 2019 and November 2020, 49 patients were screened (16 RAS mutations in LB detected) and 31 included (18 assigned to arm A and 13 to arm B). The study was prematurely closed due to inadequate recruitment. Serious adverse events were more frequent in arm A (44% vs. 23%). Overall response rate was 33% (arm A) vs. 7.7% (arm B). Six-month progression-free survival rate was 66.7% (arm A) and 38.5% (arm B). Median progression-free survival was 11.0 months (arm A) and 4.0 months (arm B) (hazard ratio, 0.58). At disease progression, RAS or BRAF mutations in LB were found in 4/11 patients (36%) in arm A and 2/10 (20%) in arm B. CONCLUSIONS: The BEYOND study suggests a meaningful benefit of P-FOLFIRI beyond progression to P-FOLFOX in metastatic colorectal cancer patients with WT RAS status selected by LB. This strategy deserves further investigation.

Superior Outcomes With Continuing Tenofovir Versus Switching to Zidovudine in Second-Line Antiretroviral Therapy in Haiti.

We compared viral suppression rates between patients who continued tenofovir disoproxil fumarate (TDF)/lamivudine (3TC) vs switched to zidovudine (ZDV)/3TC in combination with a boosted protease inhibitor after failure of first-line efavirenz/TDF/3TC. We found higher rates of viral suppression with continued TDF/3TC compared with switching to ZDV/3TC.

A comparative study of immunotherapy as second-line treatment and beyond in patients with advanced non-small-cell lung carcinoma.

BACKGROUND: Immunotherapy has demonstrated an improved overall survival (OS) and progression-free survival (PFS) as second-line treatment and subsequent lines compared with chemotherapy. MATERIALS & METHODS: This was a retrospective review among eight medical centers comprising 100 patients with a confirmed diagnosis of non-small-cell lung carcinoma, in their second-line treatment or beyond with immune checkpoints inhibitors treatment. The current study aimed to analyze effectiveness of immunotherapy in second-line treatment or further in the Mexican population, using PFS rate, OS rate and the best objective response to treatment by RECIST 1.1 as a surrogate of effectiveness. RESULTS: In total, 100 patients met the criteria for enrollment in the current study. From the total study population, 49 patients (49.0%) were male and 51 (51.0%) were female, with an average age of 60 years and stage IV as the most prevalent clinical stage at the beginning of the study. A total of 61 patients (61.0%) had partial response; 11 (11.0%) stable disease; 2 (2.0%), complete response, 4 (4.0%), progression; and 22 (22.0%) were nonevaluable. We found a median PFS of 4 months (95% CI: 3.2-4.7 months) and an OS of 9 months (95% CI: 7.2-10.7 months). CONCLUSION: The response to immunotherapy is similar, with an improvement in OS and PFS, independent of which drug is used. Patients using nivolumab had a better survival, although that was not statistically significant.

Prognostic factors in advanced pancreatic ductal adenocarcinoma patients-receiving second-line treatment: a single institution experience.

BACKGROUND: Second-line (2L) treatments for advanced pancreatic ductal adenocarcinoma (PDAC) achieve a modest benefit at the expense of potential toxicity. In the absence of predictive factors of response, the identification of prognostic factors could help in the therapeutic decisions-making. The purpose of this study was to assess the prognostic factors associated with shorter survival in patients with advanced PDAC who received 2L treatment. METHODS: We conducted a single institution retrospective study, which included all patients with advanced PDAC who received 2L treatment between September 2006 and February 2020 at La Paz University Hospital, Madrid (Spain). Significant variables in the logistic regression model were used to create a prognostic score. RESULTS: We included 108 patients. The median overall survival (OS) was 5.10 months (95%CI 4.02-6.17). In the multivariate analysis, time to progression (TTP) shorter than 4 months after first-line treatment (OR 4.53 [95%CI 1.28-16.00] p = 0.01), neutrophil-to-lymphocyte ratio (NLR) greater than 3 at the beginning of 2L (OR 9.07 [95%CI 1.82-45.16] p = 0.01) and CA-19.9 level higher than the upper limit of normal at the beginning of 2L (OR 7.83 [95%CI 1.30-49.97] p = 0.02) were independently associated with OS shorter than 3 months. The prognostic score classified patients into three prognostic groups (good, intermediate and poor) with significant differences in OS (p < 0.001). CONCLUSIONS: TTP shorter than 4 months after first-line treatment, NLR greater than 3 and CA-19.9 level higher than the upper limit of normal at the beginning of 2L were associated with shorter overall survival. We developed a prognostic score that classifies patients with advanced PDAC into three prognostic groups after progression to the first-line. This score could help in the decision-making for 2L treatment.

Poor quality of life and incomplete self-reported adherence predict second-line ART virological failure in resource-limited settings.

We evaluated health-related quality of life (QoL) and self-reported incomplete adherence as predictors of early second-line antiretroviral (ART) virological failure (VF). ACTG A5273 study participants completed the ACTG SF-21 measure which has 8 QoL domains. We used exact logistic regression to assess the association of QoL at baseline and week 4 with early VF adjusted for self-reported adherence. Of 500 individuals (51% women, median age 39 years) in this analysis, 79% and 75% self-reported complete adherence (no missing doses in the past month) at weeks 4 and 24, respectively. Early VF was experienced by 7% and more common among those who self-reported incomplete adherence. Participants with low week 4 QoL scores had higher rates of early VF than participants with high scores. After adjusting for self-reported adherence at week 4, VL and CD4 at baseline, cognitive functioning, pain and mental health domains were significantly associated with subsequent early VF. In this post-hoc analysis, poorer QoL adds to self-reported incomplete adherence after 4 weeks of second-line ART in predicting VF at week 24. Evaluation is needed to assess whether individuals with poorer QoL might be targeted for greater support to reduce risk of VF.Trial registration: ClinicalTrials.gov identifier: NCT01352715.

Prospective Evaluation of the First Option, Second-Line Therapy in Childhood Chronic Immune Thrombocytopenia: Splenectomy or Immunomodulation.

OBJECTIVE: To describe 4 subgroups of pediatric patients treated with splenectomy, hydroxychloroquine, azathioprine, or rituximab as the first-option, second-line treatment for chronic immune thrombocytopenia. STUDY DESIGN: Selection of patients with chronic immune thrombocytopenia from the French national prospective cohort of pediatric autoimmune cytopenia OBS'CEREVANCE and VIGICAIRE study, treated by splenectomy, hydroxychloroquine, azathioprine, or rituximab as a first second-line treatment. RESULTS: For 137 patients, treated between 1989 and 2016, the median follow-up after diagnosis and after treatment initiation was 8.5 (2.8-26.4) years and 4.7 (1.1-25.1) years, respectively. Median age at diagnosis and at initiation of treatment were 9 (0.7; 16) and 12 (2; 18.1) years, respectively without significant difference between subgroups. For the whole cohort, 24-month event-free survival was 62% (95% CI 55; 71). It was 85% (95% CI 77; 95) for the 56 patients treated with splenectomy, 60% (95% CI 44; 84) for the 23 patients treated with rituximab, 46% (95% CI 30; 71) for the 24 patients treated with azathioprine, and 37% (95% CI 24; 59) for the 34 patients treated with hydroxychloroquine (log-rank P < .0001). For the splenectomy subgroup, being older than 10 years at splenectomy tended to improve event-free survival (P = .05). Female teenagers with antinuclear antibody positivity benefited from hydroxychloroquine therapy. CONCLUSIONS: This national study, limiting pitfalls in the analysis of the effects of second-line therapies, showed that splenectomy remains the treatment associated with the better response at 24 months.

Expanded access to viral load testing and use of second line regimens in Haiti: time trends from 2010-2017.

BACKGROUND: Haiti initiated the scale-up of HIV viral load (VL) testing in 2015-2016, with plans to achieve 100% coverage for all patients on antiretroviral therapy (ART) for treatment of HIV/AIDS. In the absence of HIV drug susceptibility testing, VL testing is a key tool for monitoring response to ART and optimizing treatment results. This study describes trends in expanded use of VL testing, VL results, and use of second-line ART regimens, and explores the association between VL testing and second-line regimen switching in Haiti from 2010 to 2017. METHODS: We conducted a retrospective cohort study with 66,042 patients drawn from 88 of Haiti's 160 national ART clinics. Longitudinal data from the iSanté electronic data system was used to analyze the trends of interest. We described patients' VL testing status in five categories based on up to two most recent VL test results: no test; suppressed; unsuppressed followed by no test; re-suppressed; and confirmed failure. Among those with confirmed failure, we described ART adherence level. Finally, we used Cox proportional hazards regression to estimate the risk of second-line regimen switching by VL testing status, after adjusting for other individual characteristics. RESULTS: The number of patients who had tests done increased annually from 11 in 2010 to 18,828 in the first 9 months of 2017, while the number of second-line regimen switches rose from 21 to 279 during this same period. Compared with patients with no VL test, the hazard ratio (HR) for switching to a second-line regimen was 22.2 for patients with confirmed VL failure (95% confidence interval [CI] for HR: 18.8-26.3; p < 0.005) after adjustment for individual characteristics. Among patients with confirmed VL failure, 44.7% had strong adherence, and fewer than 20% of patients switched to a second-line regimen within 365 days of VL failure. CONCLUSIONS: Haiti has significantly expanded access to VL testing since 2016. In order to promote optimal patient health outcomes, it is essential for Haiti to continue broadening access to confirmatory VL testing, to expand evidence-based initiatives to promote strong ART adherence, and to embrace timely switching for patients with confirmed ART failure despite strong ART adherence.

A new scenario in metastatic renal cell carcinoma: a SOG-GU consensus.

BACKGROUND: This article describes and compares approved targeted therapies and the newer immunotherapy agents. MATERIALS AND METHODS: This article especially performs an in-depth review of currently available data for tivozanib, explaining its mechanism of action, its safety profile and its role as an efficacy drug in the management of renal cancer. RESULTS: Despite the fact that the treatment of advanced RCC has been dramatically modified in recent years, durable remissions are scarce and it remains a lethal disease. For first- and second-line therapy, there is now growing evidence to guide the selection of the appropriate treatment. CONCLUSIONS: Several TKIs are standard of care at different settings. Among those approved TKIs, tivozanib has similar efficacy than others with a better safety profile. The use of prognostic factors is critical to the selection of optimal therapy.

Second-Line Injectable Drugs for the Treatment of Multidrug-Resistant Tuberculosis: Why do We Keep Using Them?

Second-line injectable drugs (kanamycin, amikacin and capreomycin) have been an integral part of the multidrug-resistant tuberculosis (MDR-TB) treatment regimen for decades, despite their known association with renal failure and ototoxicity. Unfortunately, there are many countries that haven't included new or reused drugs in their treatment regimens for MDR-TB and still depend on second-line injectable drugs (SLIDs) in order to have a sufficient amount of effective drugs in their regimens. Our purpose is to show the frequency and severity of the ototoxicity associated with the use of SLIDs only detected initially by means of an audiometry. We conducted a retrospective analysis including all the patients who received treatment regimens with SLIDs from 2010 to 2017 in a tuberculosis clinic in Mexico. 47 patients who received SLIDs (amikacin, kanamycin, capreomycin) were included in the analysis. The mean age was 40.3 ± 16.4 years. Thirty one patients (63.3%) had previously received TB treatment in the past. The most commonly used SLID was amikacin in 33 cases (67.3%), followed by capreomycin in 14 cases (28.6%). Twenty seven patients (55.1%) developed significant hearing loss (> 40 dB), and 13 patients (26.5%) developed severe or profound hearing loss (> 70 dB). Severe hearing loss is a common, irreversible and now unnecessary complication of the MDR/RR-TB (multidrug- and rifampicin-resistant tuberculosis) treatment, since the SLIDs may and shall be substituted by new and reused, more effective and far less toxic drugs.

Combination of pentoxifylline and α-galactosylceramide with radiotherapy promotes necro-apoptosis and leukocyte infiltration and reduces the mitosis rate in murine melanoma.

Despite the success for the treatment of melanoma such as targeted molecular therapy, the use of such treatments are expensive For this reason, this study was carried out to explore the anti-cancer properties of available drugs that are able to modify the melanoma prognosis. The study was conducted in two phases: Evaluation of pharmacological effects of pentoxifylline (PTX) administered above (60 mg/kg) which is the therapeutic dose that is aimed at reducing the side-effect of radiotherapy, and of α- galactosylceramide (GalCer) administered at 100 µg/kg, as well as their combination using a murine model (BDF1 mice) of melanoma cell line (B16-F1, ATCC). For the radiotherapy phase, 9 Gy was applied in the tumor area, before (3 days), during (30 min) and after (3 days) the PTX + GalCer treatment. In both study phases, the mitosis rate, leukocyte infiltration and necro-apoptosis were assessed using histological and immunohistochemical approach and tumor volume evaluation as biomarkers. All treatments showed good prognosis results estimated as reduction of mitosis rate (PTX + GalCer after radiotherapy and GalCer), increased leukocyte infiltrate (PTX + GalCer after radiotherapy and GalCer) and necro-apoptosis augmentation (PTX + GalCer after radiotherapy and radiotherapy control). Nevertheless, a lower development of tumor volume was found in GalCer treatment. In this way, it is possible to suggest that the integrated treatment with immuno-stimulators such as GalCer, plus drug used for peripheral vascular disease (PTX) after radiotherapy is probably an alternative for controlling aggressive melanoma in murine model.

A comprehensive analysis of factors related to carmustine/bevacizumab response in recurrent glioblastoma.

PURPOSE: Patients with recurrent glioblastoma (rGBM) have a poor prognosis, with survival ranging from 25 to 40 weeks. Antiangiogenic agents are widely used, showing a variable response. In this study, we explored the efficacy of carmustine plus bevacizumab (BCNU/Bev) for treating rGBM. METHODS/PATIENTS: In this study, we assessed 59 adult patients with histologically confirmed rGBM who were treated with BCNU/Bev as second-line regimen. The response rate (RR), progression-free survival (PFS) and overall survival (OS) were evaluated according to their molecular expression profile, including CD133 mRNA expression, MGMT methylation (pMGMT), PDGFR amplification, YKL40 mRNA expression, IDH1/2 condition, p53 and EGFRvIII mutation status. RESULTS: Median follow-up was 18.6 months, overall RR to the combination was 56.3%, and median PFS was 9.0 months (95% CI 8.0-9.9). OS from time of diagnosis was 21.0 months (95% CI 13.2-28.7) and from starting BCNU/Bev it was 10.7 months (95% CI 9.5-11.8). IDH1/2 mutations were found in 30.5% of the patients, pMGMT in 55.9% and high CD133 mRNA expression in 57.6%. Factors which positively affected PFS included performance status (p = 0.015), IDH+ (p = 0.05), CD133 mRNA expression (p = 0.009) and pMGMT+ (p = 0.007). OS was positively affected by pMGMT+ (p = 0.05). Meanwhile, YKL40 negatively affected PFS (p = 0.01) and OS (p = 0.0001). Grade ≥ 3 toxicities included hypertension (22%) and fatigue (12%). CONCLUSIONS: BCNU/Bev is a safe and tolerable treatment for rGBM. Patients with MGMT+/IDH+ derive the greatest benefit from the treatment combination in the second-line setting. Nonetheless, high YKL40 expression discourages the use of antiangiogenic therapy.

Efficacy of nintedanib and docetaxel in patients with advanced lung adenocarcinoma treated with first-line chemotherapy and second-line immunotherapy in the nintedanib NPU program.

PURPOSE: Both nintedanib/docetaxel and anti-PD-1/PD-L1 immunotherapies have demonstrated efficacy as second-line treatment of patients with advanced lung adenocarcinoma. This is the first report on the efficacy of the nintedanib/docetaxel combination following first-line platinum-based chemotherapy and subsequent immunotherapy in a real-world setting. METHODS/PATIENTS: From May 2014 to December 2015, 390 patients in 108 Spanish centres enrolled in the nintedanib named patient use program. Inclusion criteria were advanced lung adenocarcinoma with progressive disease following at least one line of platinum-based doublet chemotherapy. The objective was to evaluate the efficacy of the nintedanib/docetaxel combination in patients who also received immunotherapy. RESULTS: Eleven patients met the inclusion criteria; with a median age of 67 years. PD-L1 expression was positive in six patients. Median progression-free survival (PFS) of first-line platinum-based chemotherapy was 3.3 months (95% CI 1.9-4.6). Second-line immunotherapy was pembrolizumab (36.5%), atezolizumab (36.5%) or nivolumab (27%). Median PFS of second-line immunotherapy was 2.3 months (95% CI 0-6.1). The overall response rate (ORR) to second-line immunotherapy was 18% with a disease-control rate (DCR) of 45%. Median PFS of nintedanib/docetaxel was 3.2 months (95% CI 1.9-4.5). Best response was partial response in four patients (36%), stable disease in five patients (46%), and progressive disease in two patients (18%), for an ORR of 36% and a DCR of 82%. CONCLUSION: Our experience suggests an encouraging efficacy of nintedanib/docetaxel in patients with adenocarcinoma NSCLC pretreated with platinum-based doublet chemotherapy and immunotherapy, reinforcing the importance of an optimal therapeutic sequence for managing advanced lung adenocarcinoma.

Beyond first-line systemic treatment for metastatic urothelial carcinoma of the bladder.

Metastatic urothelial carcinoma of the bladder is a rarely curable disease. Patients receive systemic therapy with limited response rates and survival benefits. The rescue regimens of these patients who have failed first-line treatment had remained problematic until the recent advances. Several trials with novel regimens, including immune checkpoint inhibitors and targeted therapy, to salvage relapsed urothelial carcinoma of the bladder have recently been published. However, the choice of an optimal treatment regimen remains challenging in the absence of randomized trials comparing regimen sequences. Daily clinical cases provoke the question of whether there is a preferred second-line regimen. This paper provides an overview of recent trials and proposes a management algorithm based on subgroup analyses and prognostic features.

Second-Line Treatment for Advanced Pancreatic Adenocarcinoma: Is There a Role for Gemcitabine?

PURPOSE: Advanced pancreatic adenocarcinoma (PA) is an aggressive disease that has poor prognosis and frequently interferes with patient's quality of life. There has been progress in first-line regimens; however, there is no standard second-line regimen. The aim of this study is to analyze second-line gemcitabine after first-line fluorouracil (FU) + leucovorin (LV) + irinotecan + oxaliplatin (FOLFIRINOX) regimen. METHODS: This study included consecutive patients with advanced PA treated at Hospital Sirio-Libanês from 2011 to 2016. The patients received FOLFIRINOX as first-line treatment and upon progression, received gemcitabine alone. Survival analysis was performed using the Kaplan-Meier method. RESULTS: A total of 54 patients were evaluated. Most patients were male (61.1%) and most had an ECOG performance status of 0 or 1 prior to the beginning of second-line treatment (66.6%). The mean number of gemcitabine cycles was 3.4. Most patients had disease progression as the best response to treatment (75.9%), 11.1% had stable disease, and 9.3% experienced a partial response. The median progression-free survival was 1.7 months, and the median overall survival was 6.8 months. CONCLUSIONS: Gemcitabine alone did not show meaningful clinical benefit as second-line treatment after FOLFIRINOX.
