RESUMO

Purpose: Due to the shortcomings of nanocarriers, the development of carrier-free nanodelivery systems has attracted more and more attention in cancer treatment. However, there are few studies on carrier-free nanosystems that can simultaneously achieve monitoring functions. Here a multifunctional carrier-free nanosystem loaded with curcumin and irinotecan hydrochloride was established for the treatment and monitoring of gastric cancer. Methods: In this study, an irinotecan hydrochloride-curcumin nanosystem in the early stage (the system is named SICN) was prepared. Based on the fluorescence of curcumin, flow cytometry, laser confocal microscopy, and zebrafish fluorescence imaging were used to study the monitoring function of SICN in vivo and in vitro. In addition, HGC-27 human gastric cancer cells were used to study SICN cytotoxicity. Results: Flow cytometry and zebrafish fluorescence imaging monitoring results showed that the uptake of SICN was significantly higher than free curcumin, and the excretion rate was lower. SICN had higher accumulation and retention in cells and zebrafish. Laser confocal microscopy monitoring results showed that SICN was internalized into HGC-27 cells through multiple pathways, including macropinocytosis, caveolin, and clathrin-mediated and clathrin -independent endocytosis, and distributed intracellularly throughout the whole cytoplasm, including lysosomes and Golgi apparatus. In vitro cell experiments showed that SICN nanoparticles were more toxic than single components, and HGC-27 cells had more absorption and higher toxicity to nanoparticles under slightly acidic conditions. Conclusion: SICN is a promising carrier-free nanoparticle, and the combination of two single-component therapies can exert a synergistic antitumor effect. When exposed to a tumor acidic environment, SICN showed stronger cytotoxicity due to charge conversion. More importantly, the nanoparticles' self-monitoring function has been developed, opening up new ideas for combined tumor therapy.

RESUMO

RATIONALE: Endoscopic ultrasonography-guided tissue acquisition (EUS-TA) has become the norm for the diagnosis of pancreatic solid lesions. EUS-TA is relatively safe, but various complications can occur. Infected pancreatic necrosis (IPN) is a rare but serious complication. The latest guidelines suggest that all invasive interventions in patients with IPN should be delayed until walled-off necrosis appears. PATIENT CONCERNS: A 73-year-old man was referred to our hospital with double primary cancers including gallbladder and pancreas. We performed EUS-TA on metastatic pancreatic tail cancer to confirm histologic diagnosis. Six days after the procedure, he developed abdominal pain and fever. DIAGNOSES: The patient's laboratory findings showed leukocytosis and C-reactive protein elevation. Fluid collection around pancreas tail and stomach was detected in computed tomography (CT) scan, and the patient was diagnosed with IPN. INTERVENTIONS AND OUTCOMES: EUS-guided endoscopic transmural drainage (EUS-TD) was performed for the treatment of IPN. Two days after the procedure with antibiotics, his CRP level decreased abruptly, and he received chemotherapy for the treatment of pancreatic ductal adenocarcinoma (PDAC) 5 days after the procedure. He was discharged from our hospital without complications 15 days after chemotherapy. LESSONS: In selected patients with PDAC, early endoscopic drainage may be recommended as treatment for IPN resulting from complications of EUS-TA.

RESUMO

Oxaliplatin (OX) and irinotecan (IRI) are used as key drugs for the first-line treatment of metastatic colorectal cancer (mCRC). However, no biomarkers have been identified to decide which of the drugs is initially used. In this translational research (TR) of the TRICOLORE trial, the advanced colorectal cancer subtype (aCRCS) was analyzed as a potential biomarker for the selection of OX or IRI. We collected 335 (68.8%) formalin-fixed, paraffin-embedded (FFPE) primary tumor specimens from 487 patients registered in the TRICOLORE trial and performed direct sequencing and immunohistochemical staining of CRC-related genes, comprehensive gene-expression analysis, and genome-wide methylation analysis. The progression-free survival (PFS) of the IRI group was significantly better compared with the OX group in BRAF wild-type (WT), PTEN-positive, and aCRCS A1 patients. Among the molecular factors, aCRCS were only associated with the PFS of OX and IRI groups. The PFS of the IRI group was significantly better compared with the OX group in aCRCS A1 + B1 (hazard ratio [HR] = 0.58; 95% confidence interval [CI] = 0.41-0.82; P = .0023). In contrast, the OX group had better PFS compared with the IRI group in aCRCS B2, although this was not statistically significant (HR = 1.66; 95% CI = 0.94-2.96; P = .083). Nearly half of patients with mCRC (46.8%, aCRCS A1 + B1) respond well to IRI, while only about 18.5% (aCRCS B2) of patients with mCRC responded well to OX. In conclusion, the aCRCS might be a predictive factor for the clinical outcomes of OX-based and IRI-based therapies.

RESUMO

ABSTRACT: Currently, the combination of 5-fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) is the standard therapy for metastatic pancreatic cancer. In recent years, FOLFIRINOX-based neoadjuvant therapy for locally advanced pancreatic cancer (LAPC) has been gaining an increasing amount of attention, owing to its ability to reduce disease stage and transform LAPC to borderline resectable or even resectable pancreatic cancer. Accordingly, we aimed to evaluate the efficacy of first-line FOLFIRINOX chemotherapy in patients with LAPC.We searched PubMed, Embase, and Cochrane Library from the time of establishment till January 1, 2020 and included studies focusing on LAPC patients who received FOLFIRINOX as first-line neoadjuvant treatment. The primary outcomes were: resection rate and radical (R0) resection rate while the secondary outcomes were: objective response rate, overall survival, progression-free survival, and rate of grade 3 to 4 adverse events. The meta package for R 3.6.2 was used for heterogeneity and publication bias testing.Twenty-one studies, including 653 patients with LAPC, were selected. After treatment with FOLFIRINOX, the resection rate was 26% (95% confidence interval [CI] = 20%-32%, I2 = 61%) and R0 resection rate was 88% (95% CI = 78%-95%, I2 = 62%). The response rate was 34% (95% CI = 25%-43%, I2 = 56%). The median overall survival and progression-free survival durations ranged from 10.0 to 32.7 months and 3.0 to 25.3 months, respectively. The observed grade 3 to 4 adverse events were neutropenia (20.0 per 100 patients, 95% CI = 14%-27%, I2 = 75%), febrile neutropenia (7.0 per 100 patients, 95% CI = 5%-9%, I2 = 42%), thrombocytopenia (6.0 per 100 patients, 95% CI = 5%-8%, I2 = 27%), nausea/vomiting (7.0 per 100 patients, 95% CI = 7%-12%, I2 = 76%), diarrhea (10.0 per 100 patients, 95% CI = 8%-12%, I2 = 38%), and fatigue (9.0 per 100 patients, 95% CI = 7%-11%, I2 = 43%).FOLFIRINOX-based neoadjuvant chemotherapy has the potential to improve the rates of resection, R0 resection, and median OS in LAPC. Our results require further validation in large, high-quality randomized controlled trials.

RESUMO

PURPOSE: Transarterial chemoembolisation (TACE) using irinotecan-eluting beads is an additional treatment option for colorectal cancer liver metastases (CRLM) patients that are not eligible for curative treatment approaches. This interim analysis focuses on feasibility of the planned statistical analysis regarding data distribution and completeness, treatment intention, safety and health-related quality of life (HRQOL) of the first 50 patients prospectively enrolled in the CIrse REgistry for LifePearl™ microspheres (CIREL), an observational multicentre study conducted across Europe. METHODS: In total, 50 patients ≥ 18 years diagnosed with CRLM and decided to be treated with irinotecan-eluting LifePearl™ microspheres TACE (LP-irinotecan TACE) by a multidisciplinary tumour board. There were no further inclusion or exclusion criteria. The primary endpoint is the categorisation of treatment intention, and secondary endpoints presented in this interim analysis are safety, treatment considerations and HRQOL. RESULTS: LP-irinotecan TACE was conducted in 42% of patients as salvage therapy, 20% as an intensification treatment, 16% as a first-line treatment, 14% a consolidation treatment and 8% combination treatment with ablation with curative intent. Grade 3 and 4 adverse events were reported by 4% of patients during procedure and by 10% within 30 days. While 38% reported a worse, 62% reported a stable or better global health score, and 54% of patients with worse global health score were treated as salvage therapy patients. CONCLUSION: This interim analysis confirms in a prospective analysis the feasibility of the study, with an acceptable toxicity profile. More patients reported a stable or improved HRQOL than deterioration. Deterioration of HRQOL was seen especially in salvage therapy patients. TRIAL REGISTRATION: NCT03086096.

RESUMO

BACKGROUND: The optimal preoperative treatment for locally advanced pancreatic cancer is unknown. We aimed to compare the efficacy and safety of nab-paclitaxel plus gemcitabine with nab-paclitaxel plus gemcitabine followed by fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) as multidrug induction chemotherapy regimens in locally advanced pancreatic cancer. METHODS: In this open-label, multicentre, randomised phase 2 study, done at 28 centres in Germany, eligible patients were adults (aged 18-75 years) with an Eastern Cooperative Oncology Group performance status of 0 or 1 and histologically or cytologically confirmed, treatment-naive locally advanced pancreatic adenocarcinoma, as determined by local multidisciplinary team review. After two cycles of nab-paclitaxel 125 mg/m2 plus gemcitabine 1000 mg/m2 (administered intravenously on days 1, 8, and 15 of each 28-day cycle), patients without progressive disease or unacceptable adverse events were randomly assigned (1:1) to receive either two additional cycles of nab-paclitaxel plus gemcitabine (nab-paclitaxel plus gemcitabine group) or four cycles of sequential FOLFIRINOX (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, irinotecan 180 mg/m2, fluorouracil 400 mg/m2 by intravenous bolus followed by a continuous intravenous infusion of 2400 mg/m2 for 46 h on day 1 of each 14-day cycle; sequential FOLFIRINOX group). Randomisation was done by the clinical research organisation on request of the trial centre using a permuted block design (block size 2 and 4). Patients, investigators, and study team members were not masked to treatment allocation. The primary endpoint was surgical conversion rate (complete macroscopic tumour resection) in the randomised population by intention-to-treat analysis, which was assessed by surgical exploration in all patients with at least stable disease after completion of induction chemotherapy. This trial is registered with ClinicalTrials.gov, NCT02125136. FINDINGS: Between Nov 18, 2014, and April 27, 2018, 168 patients were registered and 130 were randomly assigned to either the nab-paclitaxel plus gemcitabine group (64 patients) or the sequential FOLFIRINOX group (66 patients). Surgical exploration after completed induction chemotherapy was done in 40 (63%) of 64 patients in the nab-paclitaxel plus gemcitabine group and 42 (64%) of 66 patients in the sequential FOLFIRINOX group. 23 patients in the nab-paclitaxel plus gemcitabine group and 29 in the sequential FOLFIRINOX group had complete macroscopic tumour resection, yielding a surgical conversion rate of 35·9% (95% CI 24·3-48·9) in the nab-paclitaxel plus gemcitabine group and 43·9% (31·7-56·7) in the sequential FOLFIRINOX group (odds ratio 0·72 [95% CI 0·35-1·45]; p=0·38). At a median follow-up of 24·9 months (95% CI 21·8-27·6), median overall survival was 18·5 months (95% CI 14·4-21·5) in the nab-paclitaxel plus gemcitabine group and 20·7 months (13·9-28·7) in the sequential FOLFIRINOX group (hazard ratio 0·86 [95% CI 0·55-1·36]; p=0·53). All other secondary efficacy endpoints, such as investigator-assessed progression-free survival, radiographic response rate, CA 19-9 response rate, and R0 resection rate, were not significantly different between the two treatment groups except for improved histopathological downstaging in evaluable resection specimens from the sequential FOLFIRINOX group (ypT1/2 stage: 20 [69%] of 29 patients in the sequential FOLFIRINOX group vs four [17%] of 23 patients in the nab-paclitaxel plus gemcitabine group, p=0·0003; ypN0 stage: 15 [52%] of 29 patients in the sequential FOLFIRINOX group vs four [17%] of 23 patients in the nab-paclitaxel plus gemcitabine group, p=0·02). Grade 3 or higher treatment-emergent adverse events during induction chemotherapy occurred in 35 (55%) of 64 patients in nab-paclitaxel plus gemcitabine group and in 35 (53%) of 66 patients in the sequential FOLFIRINOX group. The most common of which were neutropenia (18 [28%] in nab-paclitaxel plus gemcitabine group, 16 [24%] in the sequential FOLFIRINOX group), nausea and vomiting (two [3%] in nab-paclitaxel plus gemcitabine group, eight [12%] in the sequential FOLFIRINOX group), and bile duct obstruction with cholangitis (six [9%] in nab-paclitaxel plus gemcitabine group, seven [11%] in the sequential FOLFIRINOX group). No deaths were caused by treatment-related adverse events during the induction chemotherapy phase. INTERPRETATION: Our findings suggest that nab-paclitaxel plus gemcitabine is similarly active and safe as nab-paclitaxel plus gemcitabine followed by FOLFIRINOX as multidrug induction chemotherapy regimens for locally advanced pancreatic cancer. Although conversion to resectability was achieved in about a third of patients, additional evidence is required to determine whether this translates into improved overall survival. FUNDING: Celgene.

RESUMO

Purpose: Nanoparticle (NP)-based chemo-photothermal therapy (CPT) has been shown to be a promising non-invasive approach for antitumor treatment. However, NPs must overcome the limitations of opsonization, clearance of the reticuloendothelial system, and ineffective targeting of tumor tissue sites. To solve these problems, stem cell membrane (SCM)-camouflaged polydopamine nanoparticles (PDA@SCM NPs) carrying the hydrophobic anticancer drug 7-ethyl-10-hydroxycamptothecin (SN38) were constructed for CPT of malignant bone tumors. Methods: We developed umbilical-cord mesenchymal stem cell membrane-coated polydopamine nanoparticles encapsulating SN38 (PDA-SN38@SCM NPs) as an efficient tumor-targeting drug-delivery platform for CPT of malignant bone tumors. We characterized PDA@SCM NPs and evaluated the biocompatibility and anti-phagocytosis properties of PDA@SCM NPs. The antitumor activity of PDA-SN38@SCM NPs was evaluated in MG63 lines and an MG63 xenograft model in mice. Results: Synthesized PDA-SN38@SCM NPs retained an excellent photothermal effect after SN38 loading. The drug release of PDA-SN38@SCM NPs could be triggered by near-infrared irradiation and an acidic stimulus. PDA@SCM NPs exhibited lower nonspecific macrophage uptake, longer retention in blood, and more effective accumulation at tumor sites than that shown by PDA NPs. Confocal laser scanning microscopy (CLSM) and flow cytometry showed that MG63 cells took up more PDA-SN38@SCM NPs than PDA-SN38 NPs. In vitro and in vivo antitumor studies demonstrated the outstanding performance of PDA-SN38@SCM NPs in synergistic CPT for bone tumors. Conclusion: PDA-SN38@SCM NPs demonstrated an extraordinary synergistic CPT effect and could be a promising strategy for the treatment of malignant bone tumors.

RESUMO

The phase III West Japan Oncology Group (WJOG) 4407G study showed noninferiority of folinic acid, bolus/continuous fluorouracil, and irinotecan plus bevacizumab to modified folinic acid, bolus/continuous fluorouracil, and oxaliplatin 6 plus bevacizumab in progression-free survival (PFS) as first-line chemotherapy for patients with metastatic colorectal cancer. The aim of this study was to evaluate the predictive and prognostic value of morphologic response in patients with colorectal liver metastases (CLM) as a post hoc analysis of the WJOG4407G study.Morphologic response was assessed by comparing contrast-enhanced computed tomography (CT) images at baseline and week 8. Three blinded radiologists evaluated CT images and classified their response as optimal, incomplete, or no response according to the morphologic criteria. Response evaluation criteria in solid tumors (RECIST) response, early tumor shrinkage (ETS), and depth of response (DpR) were also evaluated.Among 395 patients who were eligible for efficacy analysis in the WJOG4407G study, 70 patients had liver-limited disease. We finally evaluated 55 of these patients. Optimal morphologic response was identified in 19 of 55 patients (34.5%). The median PFS was 10.7 months for patients with optimal response and 10.1 months in those with incomplete/no response (log-rank, P = .96). The median overall survival (OS) was 26.2 and 35.5 months, respectively (log-rank, P = .062). According to univariate analysis, morphologic response was not associated with PFS or OS, whereas RECIST response was significantly associated with both PFS and OS, with ETS and DpR being associated with significantly longer PFS.Morphologic response might be neither a predictive nor a prognostic factor in patients with CLM undergoing chemotherapy containing bevacizumab, whereas RECIST response was significantly associated with both PFS and OS.

RESUMO

OBJECTIVE: By using the Korean Pancreatic Cancer (K-PaC) registry, we compared the clinical outcomes of FOLFIRINOX (FFX) and gemcitabine plus nab-paclitaxel (GNP) in patients with metastatic pancreatic cancer (MPC). METHODS: We constructed a web-based database of 3748 anonymized patients diagnosed with pancreatic ductal adenocarcinoma. MPC patients who received first-line FFX or GNP were enrolled. Overall survival (OS), progression-free survival, grade III to IV toxicity, and cross-over treatment were analyzed. RESULTS: A total of 413 patients (232 vs. 181, FFX vs. GNP; all data are presented in this sequence) were eligible. Median age was 63 years (60 vs. 69 y) with 43% (39% vs. 47%) comprising female individuals. The major metastatic sites were the liver (64%), peritoneum (25%), and distant lymph nodes (18%). The median OS was 11.5 versus 12.7 months (hazard ratio [HR]=0.87, 95% confidence interval [CI]: 0.68-1.12, P=0.286), and median progression-free survival was 7.5 versus 8.1 months (HR=0.92, 95% CI: 0.70-1.20, P=0.517), respectively. The frequency of grade III to IV febrile neutropenia was higher in the FFX group (18% vs. 11%, P=0.040), and that of peripheral neuropathy was higher in the GNP group (8% vs. 14%, P=0.046). The chance to receive second-line chemotherapy was higher in the GNP group (45% vs. 56%, P=0.036). In the cross-over treatment, the median OS of the FFX-GNP group (n=43) and the GNP-FFX group (n=47) was 16.8 versus 17.7 months (HR=0.79, 95% CI: 0.44-1.41, P=0.425). CONCLUSIONS: FFX and GNP showed similar efficacy and comparable toxicity in MPC patients. Although the GNP group had a higher chance to receive second-line chemotherapy, they did not have improved overall survival.

RESUMO

BACKGROUND/AIM: Irinotecan is rarely used on the metastatic breast cancer (MBC) setting. S-1 is an oral mixture of tegafur, gimeracil and oteracil. We conducted this pilot study to assess efficacy and safty of chemotherapy with combined irinotecan and S-1 (IRIS). PATIENTS AND METHODS: Irinotecan was given intravenously at 80 mg/m2 on days 1 and 8 and S-1 was given orally at 80-120 mg/day depending on body surface area for 2 weeks, repeating the cycle every 3 weeks. RESULTS: Twenty-two patients were enrolled in the study. Median age was 50.5 years (range=26-72). Nineteen patients were evaluable for response. Median overall survival and progression-free survival were 672 days (95% CI=420-967) and 166 days (95% CI=76-814), respectively. CONCLUSION: The IRIS regimen has an acceptable safety profile and modest efficacy against MBC in patients previously heavily treated with chemotherapy. This regimen has potential to treat MBC.

RESUMO

BACKGROUND: More than 70% of patients with localized pancreatic cancer treated with upfront surgery develop disease recurrence. Herein we describe the radiographic patterns and timing of disease recurrence after neoadjuvant therapy and surgery in patients with pancreatic cancer. METHODS: Radiographic patterns of first disease recurrence were examined in patients with localized pancreatic cancer who completed neoadjuvant therapy and surgery. Disease recurrence was classified as local (pancreas, resection bed, or peripancreatic vasculature); regional (peritoneum or abdominal wall); or distant (liver, lung, bone). Progression-free survival was calculated from the date of diagnosis to the date of recurrence. RESULTS: Of 306 consecutive patients who completed neoadjuvant therapy and surgery, 149 (49%) had resectable pancreatic cancer and 157 (51%) had borderline resectable disease. Neoadjuvant therapy consisted of chemoradiation (32%), chemotherapy (14%), or both therapies (54%). Overall, primary therapy (including preoperative and postoperative therapy) consisted of chemoradiation alone in 29 (9%), chemotherapy alone in 14 (5%), and both therapies in 263 (86%) patients. At a median follow-up of 27 months, 186 (61%) of the 306 patients had recurrent pancreatic cancer. Sites of first recurrence were local-only in 29 (9%), regional-only in 19 (6%), distant-only in 87 (28%), and multisite in 51 (17%). The overall median progression-free survival for all patients was 24 months. Neoadjuvant chemoradiation reduced the odds of local-only recurrence (odds ratio: 0.21; 95% confidence interval: 0.06-0.77; P = .02). CONCLUSION: After neoadjuvant therapy and surgery, 9% of patients were found to have local-only recurrence. Treatment sequencing that incorporates neoadjuvant chemoradiation may improve local disease control.

RESUMO

BACKGROUND: It is unclear whether the UGT1A1 status, single heterozygous (SH) or wild type (WT), is associated with the efficacy and toxicity of irinotecan monotherapy in advanced gastric cancer (AGC). We investigated the association between clinical outcomes (efficacy and safety) and UGT1A1 status in patients who received irinotecan monotherapy. METHODS: We evaluated AGC patients who received irinotecan monotherapy between January 2011 and December 2017. Efficacy was assessed according to overall survival (OS) and progression-free survival (PFS). Toxicity was graded using the Common Toxicity Criteria for Adverse Events (version 4.0). RESULTS: A total of 100 patients were evaluated (62 and 38 patients with UGT1A1 WT and SH, respectively). In the WT and SH groups, the irinotecan dose was reduced in 19 (30.6%) and 18 (47.2%) patients (p = 0.135), respectively; treatment was delayed due to adverse events (AEs) in 19 (30.6%) and 13 (34.2%) patients (p = 0.826), respectively; the median PFS was 3.15 and 3.25 months (HR, 0.734; 95% CI 0.465-1.158; p = 0.184), respectively; and the median OS was 10.4 and 7.26 months (HR, 1.137; 95% CI 0.752-1.721; p = 0.543), respectively. Severe hematological AEs (Grade ≥ 3) were significantly more frequent in the SH group than in the WT group (63% vs. 36%; p = 0.008), while severe non-hematological AEs was not significantly different (16.0% vs. 6.5%; p = 0.173). CONCLUSION: There was no significant difference in the efficacy of irinotecan monotherapy between UGT1A1 WT and UGT1A1 SH, but UGT1A1 SH was associated with a high frequency of severe hematological toxicity.

RESUMO

BACKGROUND/AIM: FOLFIRINOX [fluorouracil (5-FU), irinotecan, oxaliplatin] and gemcitabine plus nab-paclitaxel are standard treatments for patients with pancreatic ductal adenocarcinoma (PDAC). Despite efficacy rates of less than 32%, evidence is lacking to guide the use of one drug over the other. Herein, we compared the sensitivity of patient-derived PDAC cell lines to each of these regimens. MATERIALS AND METHODS: Changes in the growth of 19 low-passage patient-derived PDAC cell lines were evaluated in response to treatment with FOLFIRINOX and gemcitabine plus paclitaxel (Gem-Pac). RESULTS: Six cell lines exhibited optimal sensitivity (high EMax and low GI50) to FOLFIRINOX and three cell lines exhibited optimal sensitivity to Gem-Pac. Several cell lines that were optimally sensitive to one drug regimen exhibited very poor response to the other. CONCLUSION: Further characterization of cancer cells exhibiting preferential sensitivity to each of these regimens may allow the identification of biomarkers to guide the selection of appropriate chemotherapy for a given patient.

RESUMO

BACKGROUND/AIM: The aim of this monocentric study was to evaluate the efficacy and tolerability of a polychemotherapy regimen based on gemcitabine, docetaxel, capecitabine, cisplatin (PDGX) as second-line for advanced pancreatic cancer after FOLFIRINOX. PATIENTS AND METHODS: Patients received FOLFIRINOX as first-line regimen were retrospectively identified between January 2016 and January 2019. After disease progression or unacceptable toxicity, patients eligible for second-line therapy were treated in our center by PDGX. RESULTS: During this period, 18 patients received PDGX regimen as second-line therapy. Main grade 3 toxicities were hematologic, which required dose adaptation in 14/18 patients. No toxic death was observed. Median second-line progression-free survival (PFS) and overall survival (OS) were 2,91 and 5,3 months, respectively. Total OS from the initiation of first-line was and 11,9 months. CONCLUSION: Second-line PDGX regimen after FOLFIRINOX failure is feasible, with notable toxicity profile and is associated with poor clinical outcomes.

RESUMO

The synchronous diagnosis of two or more primary malignancies in a patient is overall rare. This is a case report of a 70-year-old female with a history of skin squamous cell carcinoma presenting with occult hematochezia. Colonoscopy and biopsy results confirmed a microsatellite stable (MMS) adenocarcinoma in the ascending colon, and subsequent computed tomography (CT) scans identified a 3.2 cm right colonic mass and a 5.0 cm mass in the pancreatic body. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) confirmed the presence of pancreatic ductal adenocarcinoma (PDAC). The patient underwent neo-adjuvant FOLFIRINOX (folinic acid, fluorouracil, irinotecan and oxaliplatin) chemotherapy prior to the simultaneous distal pancreatectomy and right hemicolectomy for both pancreatic and colonic tumors. The pathology diagnoses included moderately differentiated pancreatic ductal carcinoma (PDAC) with histiocyte-like features (tumor stage: ypT3N1M0) and moderately differentiated colonic adenocarcinoma, intestinal type (tumor stage: ypT3N0M0). To the best of our knowledge, this is the first documented case of synchronous primary colonic adenocarcinoma and PDAC in the English literature.

RESUMO

This review proposes the hypothesis that the effectiveness of irinotecan chemotherapy might be impaired by high doses of concomitantly administered Δ9-tetrahydrocannabinol (THC). The most important features shared by irinotecan and THC, which might represent sources of potentially harmful interactions are: first-pass hepatic metabolism mediated by cytochrome P450 (CYP) enzyme CYP3A4; glucuronidation mediated by uridine diphosphate glycosyltransferase (UGT) enzymes, isoforms 1A1 and 1A9; transport of parent compounds and their metabolites via canalicular ATP-binding cassette (ABC) transporters ABCB1 and ABCG2; enterohepatic recirculation of both parent compounds, which leads to an extended duration of their pharmacological effects; possible competition for binding to albumin; butyrylcholinesterase (BChE) inhibition by THC, which might impair the conversion of parent irinotecan into the SN-38 metabolite; mutual effects on mitochondrial dysfunction and induction of oxidative stress; potentiation of hepatotoxicity; potentiation of genotoxicity and cytogenetic effects leading to genome instability; possible neurotoxicity; and effects on bilirubin. The controversies associated with the use of highly concentrated THC preparations with irinotecan chemotherapy are also discussed. Despite all of the limitations, the body of evidence provided here could be considered relevant for human-risk assessments and calls for concern in cases when irinotecan chemotherapy is accompanied by preparations rich in THC.

RESUMO

Late detection, compromised immune system, and chemotherapy resistance underlie the poor patient prognosis for pancreatic ductal adenocarcinoma (PDAC) patients, making it the 3rd leading cause of cancer-related deaths in the United States. Cooperation between the tumor cells and the immune system leads to the immune escape and eventual establishment of the tumor. For more than 20 years, sincere efforts have been made to intercept the tumor-immune crosstalk and identify the probable therapeutic targets for breaking self-tolerance toward tumor antigens. However, the success of these studies depends on detailed examination and understanding of tumor-immune cell interactions, not only in the primary tumor but also at distant systemic niches. Innate and adaptive arms of the immune system sculpt tumor immunogenicity, where they not only aid in providing an amenable environment for their survival but also act as a driver for tumor relapse at primary or distant organ sites. This review article highlights the key events associated with tumor-immune communication and associated immunosuppression at both local and systemic microenvironments in PDAC. Furthermore, we discuss the approaches and benefits of targeting both local and systemic immunosuppression for PDAC patients. The present articles integrate data from clinical and genetic mouse model studies to provide a widespread consensus on the role of local and systemic immunosuppression in undermining the anti-tumor immune responses against PDAC.

RESUMO

BACKGROUND: Trastuzumab deruxtecan (DS-8201) is an antibody-drug conjugate consisting of an anti-HER2 (human epidermal growth factor receptor 2) antibody, a cleavable tetrapeptide-based linker, and a cytotoxic topoisomerase I inhibitor. The drug may have efficacy in patients with HER2-positive advanced gastric cancer. METHODS: In an open-label, randomized, phase 2 trial, we evaluated trastuzumab deruxtecan as compared with chemotherapy in patients with HER2-positive advanced gastric cancer. Patients with centrally confirmed HER2-positive gastric or gastroesophageal junction adenocarcinoma that had progressed while they were receiving at least two previous therapies, including trastuzumab, were randomly assigned in a 2:1 ratio to receive trastuzumab deruxtecan (6.4 mg per kilogram of body weight every 3 weeks) or physician's choice of chemotherapy. The primary end point was the objective response, according to independent central review. Secondary end points included overall survival, response duration, progression-free survival, confirmed response (response persisting ≥4 weeks), and safety. RESULTS: Of 187 treated patients, 125 received trastuzumab deruxtecan and 62 chemotherapy (55 received irinotecan and 7 paclitaxel). An objective response was reported in 51% of the patients in the trastuzumab deruxtecan group, as compared with 14% of those in the physician's choice group (P<0.001). Overall survival was longer with trastuzumab deruxtecan than with chemotherapy (median, 12.5 vs. 8.4 months; hazard ratio for death, 0.59; 95% confidence interval, 0.39 to 0.88; P = 0.01, which crossed the prespecified O'Brien-Fleming boundary [0.0202 on the basis of number of deaths]). The most common adverse events of grade 3 or higher were a decreased neutrophil count (in 51% of the trastuzumab deruxtecan group and 24% of the physician's choice group), anemia (38% and 23%, respectively), and decreased white-cell count (21% and 11%). A total of 12 patients had trastuzumab deruxtecan-related interstitial lung disease or pneumonitis (grade 1 or 2 in 9 patients and grade 3 or 4 in 3), as adjudicated by an independent committee. One drug-related death (due to pneumonia) was noted in the trastuzumab deruxtecan group; no drug-related deaths occurred in the physician's choice group. CONCLUSIONS: Therapy with trastuzumab deruxtecan led to significant improvements in response and overall survival, as compared with standard therapies, among patients with HER2-positive gastric cancer. Myelosuppression and interstitial lung disease were the notable toxic effects. (Funded by Daiichi Sankyo; DESTINY-Gastric01 ClinicalTrials.gov number, NCT03329690.).
