RESUMEN
BACKGROUND: Early tumor shrinkage (ETS) is a prognostic predictor for patients treated with chemotherapy in colorectal cancer, although scarce studies evaluated its potential in locally advanced pancreatic cancer (LAPC). In this exploratory analysis of JCOG1407, a randomized phase II study comparing modified 5-fluorouracil, levofolinate, irinotecan, and oxaliplatin (mFOLFIRINOX) and gemcitabine plus nab-paclitaxel (GnP), we evaluated whether ETS can predict prognosis of patients with LAPC. METHODS: Of the 126 patients enrolled in JCOG1407, 112 with measurable lesions were included in this study. ETS was defined as a ≥20 % reduction in tumor diameter compared with baseline at the initial imaging assessment 6-10 weeks after initiating chemotherapy. Patients were divided into the ETS (achieved ETS) and non-ETS (failed to achieve ETS) groups based on their ETS status. The impact of ETS on overall survival (OS) was compared using multivariable Cox regression analysis. RESULTS: Fourteen of 55 (25.5 %) and 24 of 57 (42.1 %) patients in the mFOLFIRINOX and GnP arms, respectively, achieved ETS. In the overall population, mFOLFIRINOX arm, and GnP arm, the median OS in the ETS and non-ETS groups was 27.1 and 20.4, 29.8 and 20.6, and 24.1 and 20.4, months, respectively. The adjusted hazard ratios of OS for the ETS group in the overall population, mFOLFIRINOX arm, and GnP arm were 0.451 (95 % confidence interval [CI]: 0.270-0.754), 0.371 (95 % CI: 0.149-0.926), and 0.508 (95 % CI: 0.255-1.004), respectively. CONCLUSIONS: ETS may be a prognostic predictor in chemotherapy-naïve patients with LAPC treated with mFOLFIRINOX or GnP.
RESUMEN
BACKGROUND: Modified FOLFIRINOX (mFOLFIRINOX) is one of the standard first-line therapies in borderline resectable pancreatic cancer (BRPC) and locally advanced unresectable pancreatic cancer (LAPC). However, there is no globally accepted second-line therapy following progression on mFOLFIRINOX. METHODS: Patients with BRPC and LAPC (n = 647) treated with first-line mFOLFIRINOX between January 2017 and December 2020 were included in this retrospective analysis. The details of the treatment outcomes and patterns of subsequent therapy after mFOLFIRINOX were reviewed. RESULTS: With a median follow-up duration of 44.2 months (95% confidence interval [CI], 42.3-47.6), 322 patients exhibited disease progression on mFOLFIRINOX-locoregional progression only in 177 patients (55.0%) and distant metastasis in 145 patients (45.0%). The locoregional progression group demonstrated significantly longer post-progression survival (PPS) than that of the distant metastasis group (10.1 vs. 7.3 months, p = 0.002). In the locoregional progression group, survival outcomes did not differ between second-line chemoradiation/radiotherapy and systemic chemotherapy (progression-free survival with second-line therapy [PFS-2], 3.2 vs. 4.3 months; p = 0.649; PPS, 10.7 vs. 10.2 months; p = 0.791). In patients who received second-line systemic chemotherapy following progression on mFOLFIRINOX (n = 211), gemcitabine plus nab-paclitaxel was associated with better disease control rates (69.2% vs. 42.3%, p = 0.005) and PFS-2 (3.8 vs. 1.7 months, p = 0.035) than gemcitabine monotherapy. CONCLUSIONS: The current study showed the real-world practice pattern of subsequent therapy and clinical outcomes following progression on first-line mFOLFIRINOX in BRPC and LAPC. Further investigation is necessary to establish the optimal therapy after failure of mFOLFIRINOX.

INTRODUCTION: Original FOLFIRINOX (oFFX) is more toxic than other regimens for patients with metastatic pancreatic cancer (mPC); therefore, a modified FFX (mFFX) regimen with a reduced dosage has been used in Japanese clinical practice. However, very few studies have compared these two regimens. METHODS: This study was conducted as part of a multicenter retrospective study of 318 patients with mPC across 14 centers in Japan (NAPOLEON study). To control for potential bias and confounders, we conducted a propensity score-adjusted analysis of patient characteristics and clinical outcomes. RESULTS: oFFX and mFFX were administered to 48 and 54 patients. More patients with younger age and poorer performance status were included in the oFFX group. The overall survival (OS; median, 11.6 vs. 11.3 months; hazard ratio [HR], 0.91; 95% confidence interval [CI], 0.60-1.40; p = 0.67), progression-free survival (PFS) (median, 6.3 vs. 5.7 months; HR, 0.85; 95% CI, 0.56-1.28; p = 0.44), and overall response rate (29 vs. 26%, p = 0.71) were not significantly different for the oFFX and mFFX groups. Thrombopenia and liver dysfunction were significantly more frequent with oFFX than with mFFX. The median received dose intensity of CPT-11 was higher with oFFX than with mFFX (299 vs. 270 mg/m2/week, p < 0.01). The propensity score-adjusted analysis revealed no statistically significant differences in OS and PFS between the two groups. CONCLUSION: In our data, there was no significant difference in efficacy between mFFX and oFFX, and mFFX has fewer adverse events.

Background & objectives: FOLFIRINOX and gemcitabine plus nab-paclitaxel (GN) are the most commonly used regimens in advanced pancreatic ductal adenocarcinomas (PDACs). As there is limited data on comparison of these two regimens, the present study was aimed to compare survivals and tolerance for both regimens through a match-pair analysis. Methods: The data of 350 patients with metastatic and locally advanced PDAC, treated between January 2013 and December 2019, were retrieved. A 1:1 matching, using age and performance status, without replacement was performed by using nearest neighbour matching method. Results: A total of 260 patients (130 modified FOLFIRINOX and 130 GN) were matched. The median overall survival (OS) was 12.98 months [95% confidence interval (CI) 7.257-8.776 months] in modifications of FOLFIRINOX (mFOLFIRINOX) cohort and 12.06 months (95% CI 6.690-8.88 months) in GN group (P=0.080). The incidence of grade 3 and 4 infections, diarrhoea, oral mucositis, and fatigue was higher with mFOLFIRINOX. Patients who received second line therapy had improved OS as compared to those who did not (14.06 vs. 9.07 months, P<0.001). Interpretation & conclusions: GN and mFOLFIRINOX appear to have similar survival outcomes in an unselected match paired patient population with advanced PDAC. A markedly increased incidence of non-myelosuppressive grade 3 and grade 4 side-effects and lack of survival improvements suggest a need for nuanced use of the mFOLFIRINOX regimen. Administration of second-line chemotherapy improves OS in patients with advanced PDAC.

BACKGROUND: Modified FOLFIRINOX and gemcitabine plus nab-paclitaxel (GEM-NAB) have been recommended as first-line therapies for advanced pancreatic cancer (PC). Due to the lack of evidence to directly compare them, we conducted this network meta-analysis to indirectly compare the effectiveness and toxicity of modified FOLFIRINOX and GEM-NAB. METHODS: The eligible retrospective studies on treatments related to modified FOLFIRINOX and GEM-NAB up to 4 April 2020 were searched and assessed. We used the frequentist model to analyze the survival and toxicity data between different treatments. Pooled analysis for overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and events of toxicity were analyzed in this study. RESULTS: Twenty-two studies were involved in this network meta-analysis. The comparisons on OS and PFS showed that modified FOLFIRINOX and GEM-NAB had similar treatment efficacy (OS: 1.13; 95% CI: 0.78-1.63; PFS: HR: 1.19; 95% CI: 0.85-1.67). GEM-NAB was more effective than modified FOLFIRINOX based on the result of ORR (RR: 1.43; 95% CI: 1.04-1.96). Moreover, our analysis showed a similar toxicity profile between modified FOLFIRINOX and GEM-NAB. CONCLUSIONS: The current evidence showed that modified FOLFIRINOX and GEM-NAB were similar in survival and toxicity. Many factors should be considered for in the formulation of optimal treatment, and our meta-analysis could provide some guidance to treatment selection in the first-line setting for advanced PC.

BACKGROUND: Irreversible electroporation (IRE) is a local ablation technique utilizing high voltage, low energy direct current to create nanopores in cell membrane which disrupt homeostasis and leads to cell death. Previous reports have suggested IRE may have a role in treating borderline resectable and unresectable Stage 3 pancreatic tumors. METHODS: Patients with Stage 3 pancreatic ductal adenocarcinoma (PDAC) will be enrolled in either a randomized, controlled, multicenter trial (RCT) or a multicenter registry study. Subjects enrolled in the RCT must have no evidence of disease progression after 3 months of modified FOLFIRINOX (mFOLFIRINOX) treatment prior to being randomization to either a control or IRE arm. Post-induction and post-IRE treatment for the control and IRE arms, respectively, will be left to the discretion of the treating physician. The RCT will enroll 528 subjects with 264 per arm and include up to 15 sites. All subjects will be followed for at least 24 months or until death. The registry study will include two cohorts of patients with Stage 3 PDAC, patients who received institutional standard of care (SOC) alone and those treated with IRE in addition to SOC. Both cohorts will be required to have undergone at least 3 months of SOC without progression prior to enrollment. The registry study will enroll 532 patients with 266 patients in each arm. All patients will be followed for at least 24 months or until death. The primary efficacy endpoint for both studies will be overall survival (OS). Co-primary safety endpoints will be 1) time from randomization or enrollment in the registry to death or new onset of Grade 4 adverse event (AE), and (2 high-grade complications defined as any AE or serious AE (SAE) with a CTCAE v5.0 grade of 3 or higher. Secondary endpoints will include progression-free survival, cancer-related pain, quality of life, and procedure-related pain for the IRE arm only. DISCUSSION: These studies are intended to provide Level 1 clinical evidence and real-world data demonstrating the clinical utility and safety of the use of IRE in combination with chemotherapy in patients with Stage 3 PDAC. TRIAL REGISTRATION: Clinicaltrials.gov NCT03899636 and NCT03899649. Registered April 2, 2019. Food and Drug Administration (FDA) Investigational Device Exemption (IDE) trial G180278 approved on May 3, 2019.

BACKGROUND: Among patients with non-metastatic pancreatic cancer, 80% have high-risk, borderline resectable or locally advanced cancer, with a 5-year overall survival of 12%. MASTERPLAN evaluates the safety and activity of stereotactic body radiotherapy (SBRT) in addition to chemotherapy in these patients. METHODS AND DESIGN: MASTERPLAN is a multi-centre randomised phase II trial of 120 patients with histologically confirmed potentially operable pancreatic cancer (POPC) or inoperable pancreatic cancer (IPC). POPC includes patients with borderline resectable or high-risk tumours; IPC is defined as locally advanced or medically inoperable pancreatic cancer. Randomisation is 2:1 to chemotherapy + SBRT (investigational arm) or chemotherapy alone (control arm) by minimisation and stratified by patient cohort (POPC v IPC), planned induction chemotherapy and institution. Chemotherapy can have been commenced ≤28 days prior to randomisation. Both arms receive 6 × 2 weekly cycles of modified FOLFIRINOX (oxaliplatin (85 mg/m2 IV), irinotecan (150 mg/m2), 5-fluorouracil (2400 mg/m2 CIV), leucovorin (50 mg IV bolus)) plus SBRT in the investigational arm. Gemcitabine+nab-paclitaxel is permitted for patients unsuitable for mFOLFIRINOX. SBRT is 40Gy in five fractions with planning quality assurance to occur in real time. Following initial chemotherapy ± SBRT, resectability will be evaluated. For resected patients, adjuvant chemotherapy is six cycles of mFOLFIRINOX. Where gemcitabine+nab-paclitaxel was used initially, the adjuvant treatment is 12 weeks of gemcitabine and capecitabine or mFOLFIRINOX. Unresectable or medically inoperable patients with stable/responding disease will continue with a further six cycles of mFOLFIRINOX or three cycles of gemcitabine+nab-paclitaxel, whatever was used initially. The primary endpoint is 12-month locoregional control. Secondary endpoints are safety, surgical morbidity and mortality, radiological response rates, progression-free survival, pathological response rates, surgical resection rates, R0 resection rate, quality of life, deterioration-free survival and overall survival. Tertiary/correlative objectives are radiological measures of nutrition and sarcopenia, and serial tissue, blood and microbiome samples to be assessed for associations between clinical endpoints and potential predictive/prognostic biomarkers. Interim analysis will review rates of locoregional recurrence, distant failure and death after 40 patients complete 12 months follow-up. Fifteen Australian and New Zealand sites will recruit over a 4-year period, with minimum follow-up period of 12 months. DISCUSSION: MASTERPLAN evaluates SBRT in both resectable and unresectable patients with pancreatic ductal adenocarcinoma.

BACKGROUND: There is no established second-line treatment after failure of gemcitabine plus nab-paclitaxel (GnP) therapy for metastatic pancreatic cancer (MPC). The purpose of this study was to evaluate the efficacy and tolerability of the modified FOLFIRINOX (mFFX) as a second-line therapy for MPC and to investigate prognostic factors for survival. METHODS: From 2015 to 2019, we retrospectively reviewed the medical records of consecutive patients receiving mFFX for MPC after failure of GnP therapy. Patients were treated every 2 weeks with mFFX (intravenous oxaliplatin 85 mg/m2, intravenous irinotecan 150 mg/m2, and continuous infusion of 5-fluorouracil 2400 mg/m2 for 46 h without bolus infusion). RESULTS: In total, 104 patients received mFFX. The median overall survival (OS) was 7.0 months (95% confidence interval [CI]: 6.2-9.8) and the progression-free survival (PFS) 3.9 months (95% CI 2.8-5.0). The objective response rate was 10.6% and the disease control rate 56.7%. The median relative dose intensities of oxaliplatin, irinotecan, and infusional 5-FU were 80.0% (range 21.5-100%), 77.2% (range 38.1-100%), and 85.9% (range 36.9-100%), respectively. Grade 3-4 toxicities were reported in 57 patients (54.8%), including neutropenia, leukopenia, anemia, febrile neutropenia, and peripheral sensory neuropathy. Glasgow prognostic score and carcinoembryonic antigen level were independently associated with survival. Our prognostic model using these parameters could classify the patients into good (n = 38), intermediate (n = 47), and poor (n = 19) prognostic groups. The median OS and PFS time was 14.7 (95% CI 7.6-16.3) and 7.6 months (95% CI 4.1-10.5) for the good prognostic factors, 6.5 (95% CI 5.5-10.0) and 3.6 months (95% CI 2.7-4.8) for the intermediate prognostic factors and 5.0 (95% CI 2.9-6.6) and 1.7 months (95% CI 0.9-4.3) for the poor prognostic factors, respectively. CONCLUSIONS: The mFFX showed to be a tolerable second-line treatment for MPC after GnP failure. Our prognostic model might be useful for deciding whether mFFX is indicated in this setting.

OBJECTIVES: FOLFIRINOX (FFX) or abraxane plus gemcitabine (AG)-based chemotherapy is used widely as firstline treatment for patients with pancreatic cancer. However, their use in the elderly is discouraged because of adverse events. More clinical data about the therapeutic response and tolerability to FFX or AG in elderly patents (over 70 years old) are required. METHODS: Patients with advanced pancreatic cancer (n = 203; 131 metastatic pancreatic cancer patients (MPC) and 72 locally advanced pancreatic cancer patients (LAPC)) were treated using modified-FFX (mFFX) or AG and mFFX sequentially. The patients were grouped according to their age, patients below 70 years old and patients above 70 years old. The objective response rate (ORR), disease control rate (DCR), progression free survival (PFS), overall survival (OS) and adverse events were compared between the groups. RESULTS: The ORRs in the elderly and in patients below 70 were similar (30.0% versus 32.3%). The median OS and PFS were also similar between the groups (mOS 13.3 m vs 12.7 m, p = 0.729, HR 0.874 (95% CI 0.5310 to 1.438); mPFS mPFS 10.6 m vs 10.3 m, p = 0.363, HR 0.800 (95% CI 0.4954 to 1.293)). However, the elderly patients suffered a higher incidence of severe adverse events (50% vs. 28.3%). CONCLUSIONS: These data could provide guidance for chemotherapy use in elderly patients with advanced pancreatic cancer. Age did not affect treatment outcome; however, supportive treatment is very important for elderly patients receiving chemotherapy.

Pancreatic acinar cell carcinoma (PACC) is a very rare subtype of pancreatic cancer. Due to small number of patients, no standard chemotherapy protocol has been established. We experienced an extremely rare case of PACC with liver metastasis that showed a pathological complete response after modified FOLFIRINOX (mFFX) therapy. A 42-year-old man who underwent distal pancreatectomy for an 80 mm tumor at the pancreatic tail 3 years ago was referred to our hospital in September 2017 for the treatment of a recurrent liver tumor. Percutaneous biopsy revealed an acinar-neuroendocrine carcinoma, similar to the surgical specimen. He received eight cycles of irinotecan plus cisplatin chemotherapy. However, the tumor increased in size, and treatment was switched to mFFX therapy. The tumor in the liver shrank remarkably after nine cycles of mFFX therapy. Conversion surgery was selected, and the patient underwent hepatic left and caudate lobectomy 8 months after administration of mFFX. The resected specimen showed no viable tumor cells, indicating a pathological complete response. The histological diagnosis was reconsidered, and PACC was finally diagnosed via an additional immunohistological review. The patient has remained well with no recurrence for 6 years after surgery. This study is the first to report a case of pathological complete response with mFFX therapy for the recurrence of PACC.

Pancreatic acinar cell carcinoma (PACC) is a rare pancreatic tumor type, and ruptured pancreatic tumors are rarer. Computed tomography (CT) in a 48-year-old man incidentally revealed a raptured pancreatic tail tumor. The patient was treated conservatively because he was asymptomatic, and his general condition was stable. After a detailed examination, the pancreatic tumor was diagnosed as raptured PACC. Considering the potential infiltration of tumor cells into the hematoma within the omental sac, our decision is to initiate chemotherapy as the primary course of action. A liquid biopsy was performed, and comprehensive genomic profiling of circulating tumor DNA showed a tumor BRCA2 mutation. Chemotherapy with modified FOLFIRINOX (mFFX) was selected as the first treatment. After seven courses of mFFX, the primary tumor diminished remarkably. At this time, the radical resection was performed via distal pancreatectomy with simultaneous resection of the gastric wall and colon, which had adhered strongly to the tumor. Histopathological examination revealed that the tumor had shrunk to less than 5% of its original size due to chemotherapy (Grade 3 of Evans Classification). Devising treatment strategies for ruptured pancreatic malignant tumors is challenging due to the worsening general condition caused by severe abdominal symptoms and intra-abdominal bleeding. In this context, this case-report documents a rare instance of raptured PACC with a tumor BRCA2 mutation that underwent radical resection following mFFX treatment.
RESUMEN
Background: FOLFIRINOX, used in metastatic pancreatic cancer (MPC), is highly efficacious but also toxic. Various dose modifications for FOLFIRINOX have been introduced to reduce toxicity. However, these studies lack a unified pattern for 'planned' dose modification, and the 'actually administered' dose varied more. Objective: To map a 10-year trend for 'planned' and 'actual' doses of FOLFIRINOX and investigate the clinical outcomes according to dose modification. Data sources and methods: A comprehensive systematic literature search was conducted from January 2011 to September 2021. All studies for FOLFIRINOX as first-line treatment in MPC were considered. Selected studies were firstly classified according to prospective versus retrospective research, secondly standard versus modified FOLFIRINOX, and thirdly 'planned' versus 'actual' dose. For evidence-mapping for the trend of dose modification, we developed a web-based interactive bubble-plot program (www.RDI-map.com). Objective response rate (ORR) and hematologic toxicity were set as endpoints for the comparison of clinical outcomes according to dose modification. Results: A total of 37 studies were identified for evidence-mapping (11 prospective and 26 retrospective studies). There were 12 different types of 'planned' dose modification in FOLFIRINOX ranging 75-100% oxaliplatin, 75-100% irinotecan, 0-100% 5-fluorouracil (5-FU) bolus, and 75-133% 5-FU continuous injection. The 'actual' dose further decreased to 54-96%, 61-88%, 0-92%, and 63-98%, respectively. For the standard versus modified FOLFIRINOX, the ORR was 28.2% (95% CI: 22.5-33.9%) and 33.8% (95% CI: 30.3-37.3%), respectively (p = 0.100), and the incidence of febrile neutropenia was 11.6% (95% CI: 0-16.0%) and 5.5% (95% CI: 0-8.9%), respectively (p = 0.030). Conclusions: RDI-map.com enables multifactorial evidence-mapping for practical FOLFIRINOX dose reduction. The pattern of dose modification was not consistent across studies, and there was a significant gap between the 'planned' and 'actual' doses. Modified FOLFIRINOX showed similar efficacy to the standard regimen with reduced incidence of febrile neutropenia.
RESUMEN
BACKGROUND: After the publication of the ABC-02 trial, gemcitabine and cisplatin combination therapy (GP) became the standard first-line treatment for advanced biliary tract cancer (BTC). Despite GP therapy, most patients suffer from disease progression. The ABC-06 trial recommended FOLFOX as a second-line treatment, but its efficacy was modest. In this phase II study, we looked at the efficacy and safety of a second-line modified dose of FOLFIRINOX (mFOLFIRINOX) for patients who had failed first-line gemcitabine-based treatment. METHODS: From January 2020 to January 2021, 34 patients with advanced BTC who failed first-line gemcitabine-based chemotherapy were enrolled. We evaluated the clinical efficacy and safety outcomes of mFOLFIRINOX. RESULTS: With a median follow-up duration of 13.4 months, the median progression-free survival and overall survival was 2.8 months (95% confidence interval (CI): 1.6-4.0 months) and 6.2 months (95% CI: 5.0-7.4 months), respectively. The objective response rate was 14.7% with no complete response. The disease control rate was 61.7%, with a disease control duration of 4.2 months. Due to the rapid progression of the disease, approximately half of all patients received less than three cycles of treatment. The most common type of adverse event (AEs) was hematopoietic AEs. The incidence of non-hematopoietic AEs was relatively low. CONCLUSIONS: The efficacy of mFOLFIRINOX as a second-line treatment in advanced BTC patients after the failure of gemcitabine-based first-line treatment was replicated, albeit with slightly shorter survival results compared to previous studies. Long-term administration of mFOLFIRINOX with toxicity management might offer a survival benefit.
RESUMEN
Objectives: There is an urgent need for biomarkers that predict the survival outcome of patients diagnosed with metastatic pancreatic cancer, undergoing systemic chemotherapy. This study aimed to identify biomarkers associated with the survival of mPC patients treated with modified FOLFIRINOX (mFOLFIRINOX) as first-line chemotherapy. Methods: This was a retrospective study of 30 patients with mPC who received mFOLFIRINOX between October 2018 and March 2021. Data on carcinoembryonic antigen (CEA), cancer antigen (CA)199, interleukin (IL)-6, C-reactive protein (CRP), neutrophils, platelets, lymphocytes, and albumin were collected and dichotomized using the upper or lower limit, as appropriate. These markers were examined for their association with progression-free survival (PFS). A receiver operating characteristic (ROC) curve analysis was used to explore a suitable model to predict mFOLFIRINOX effectiveness. Results: IL-6 and CRP levels were associated with poor progression (P = 0.004 and P = <0.001, respectively) of mPC. The high IL-6 level was an independent poor prognostic factor for PFS (HR=4.66, 95%CI: 1.32-16.37, P=0.016) in the multivariable analysis. Patients with high IL-6 levels had a shorter PFS than those with low IL-6 levels (median PFS: 257 vs. 150 days, P=0.020). An increase in IL-6 and CRP levels during chemotherapy positively correlated with disease progression (P = <0.001 for both). The model combining IL-6 with CRP levels helped predict the outcomes of mPC patients treated with mFOLFIRINOX (AUC: 0.811, 95%CI: 0.639-0.983, P=0.003). Conclusions: The serum levels of IL-6 and CRP might be considered as valuable biomarkers in predicting the outcomes of patients with mPC who received the mFOLFIRINOX regimen.
RESUMEN
Objective S-1 and modified FOLFIRINOX (mFFX) were often used as the second-line chemotherapies after failure of gemcitabine plus nab-paclitaxel (GnP) in unresectable pancreatic cancer (UPC) until nanoliposomal irinotecan plus 5-fluorouracil/leucovorin therapy was approved as an alternative in Japan in 2020. However, the clinical outcomes of S-1 and mFFX after GnP have scarcely been reported. Therefore, we retrospectively studied them. Methods We extracted the clinical data of 86 patients with UPC who received second-line chemotherapy after GnP between 2015 and 2020. Among the patients who had a good organ functions and no massive ascites, 41 patients treated with S-1 and 21 treated with mFFX were enrolled. Results Compared to S-1, mFFX tended to be used for younger patients with a good general condition (median age, 63 vs. 71 years, p<0.01; and performance status 0, 67% vs. 37%, p<0.05). The median progression-free and overall survival were similar between the S-1 (3.7 and 7.2 months, respectively) and mFFX (3.3 and 7.4 months, respectively) groups. The response rate in patients with measurable lesions was 4% (n=1/23) in the S-1 group and 17% (n=2/12) in the mFFX group. The incidence of grade 3 or 4 adverse events was 20% in the S-1 group and 57% (neutrophil count decreased in 43%) in the mFFX group (p<0.01). Conclusion S-1 and mFFX were both acceptable second-line chemotherapies after GnP therapy for UPC, although attention should be paid to myelosuppression during mFFX treatment. Further studies involving nanoliposomal irinotecan plus 5-fluorouracil/leucovorin therapy are necessary to facilitate the selection of the optimal regimen for each patient.

BACKGROUND: The first-line chemotherapy regimen for advanced gallbladder cancer (GBC) is gemcitabine plus platinum (GP), despite its efficacy is limited. The current investigation is a retrospective study to compare the safety and efficacy between the modified FOLFIRINOX (mFOLFIRINOX) and gemcitabine plus oxaliplatin (GEMOX) as the first-line chemotherapy for unresectable locally advanced or metastatic GBC. METHODS: The data of patients with unresectable locally advanced or metastatic GBC, who were treated with mFOLFIRINOX or GEMOX as the first-line therapy between April 2014 and April 2018 at Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, were retrieved. This retrospective study evaluated the clinical characteristics, survival outcomes and adverse events. RESULTS: A total of 44 patients (n=25 in mFOLFIRINOX, n=19 in GEMOX) were included. There were no significant differences between groups in baseline characteristics. The median progression free survival (mPFS) was 5.0 months in the mFOLFIRINOX group and 2.5 months in the GEMOX group [P=0.021; hazard ratio (HR), 0.499; 95% CI, 0.266 to 0.937]. The median overall survival (mOS) was 9.5 months in the mFOLFIRINOX group and 7.0 months in the GEMOX group (P=0.019; HR, 0.471; 95% CI, 0.239 to 0.929). Disease control rate (DCR) was 76.0% in the mFOLFIRINOX group and 47.4% in the GEMOX group (P=0.051). The rate of grade 3-4 adverse events was 48% in the mFOLFIRINOX group and 36.8% in the GEMOX group (P=0.459). The incidence of grade 3-4 neutropenia and diarrhea were more common in the mFOLFIRINOX group, while the incidence of grade 3-4 thrombocytopenia and peripheral neuropathy were more common in the GEMOX group. CONCLUSIONS: mFOLFIRINOX might improve the poor prognosis of unresectable locally advanced or metastatic GBC, and the results need to be further verified by prospective clinical studies.
RESUMEN
BACKGROUND: The efficacy of modified FOLFIRINOX (mFOLFIRINOX) as a second-line chemotherapy treatment for metastatic pancreatic adenocarcinoma (mPAC), remains unclear. This multi-center randomised phase III trial aimed to elucidate the efficacy of mFOLFIRINOX as a second-line chemotherapy treatment for mPAC patients with good performance status. PATIENTS AND METHODS: Eighty mPAC patients (age, 19-75 years) refractory to first-line gemcitabine-based chemotherapy were randomly selected to receive mFOLFIRINOX or S-1. mFOLFIRINOX comprised oxaliplatin (65 mg/m2), irinotecan (135 mg/m2), and leucovorin (400 mg/m2) on day 1 and continuous 5-FU infusion (1000 mg/m2) over 24 h on days 1-2 every 2 weeks. S-1 comprised body surface area-dependent oral S-1, divided into two doses per day on days 1-28 every 6 weeks. RESULTS: Overall survival was the primary endpoint. The objective response and disease control rates were higher in the mFOLFIRINOX than in the S-1 group (15% versus 2%; p = .04 and 67% versus 37%; p = .007). The median progression-free survival rates were 5.2 and 2.2 months in the mFOLFIRINOX and S-1 groups, respectively (adjusted hazard ratio [HR]: .4; 95% confidence interval [CI]: .2-.6; p < .001). The median overall survival rates were 9.2 and 4.9 months in the mFOLFIRINOX and S-1 groups, respectively (adjusted HR: .4; 95% CI: .2-.7; p = .002). Grade 3-4 adverse events occurred in 56% and 17% of the patients in the mFOLFIRINOX and S-1 groups, respectively (p < .001). CONCLUSION: Administration of mFOLFIRINOX as a second-line chemotherapy treatment for mPAC patients refractory to gemcitabine-based chemotherapy resulted in increased survival rates than S-1 treatment alone.

INTRODUCTION: Combination of cisplatine and Gemcitabine (CisGem) is the reference 1st line Chemotherapy in patients with advanced biliary cancer. FOLFIRINOX demonstrated an overall survival superiority when compared to gemcitabine in 1st line for patients with metastatic pancreatic adenocarcinoma. Because of similarities between pancreatic and biliary cancers, we proposed a randomized trial comparing mFOLFIRINOX and CisGEm. AIM: PRODIGE38-AMEBICA is a phase II/III trial evaluating efficacy of modifed FOLFIRINOX (D1 bolus removed) or CisGEm on patients with locally advanced non resectable or metastatic biliary tract cancer. PATIENTS AND METHODS: Main inclusion criteria are histologically or cytologically proven biliary tract tumor (intra or extra hepatic or hilar or gallbladder carcinoma), measurable disease (metastases and/or primary tumor), Bilirubin <1,5â¯N and transaminases <5â¯N. The randomization (ratio 1:1) will be stratified on center, stage of the disease, tumor localization and previous adjuvant treatment. The Phase II trial has an objective of 73% patients alive and without progression at 6â¯months for Folfirinox (versus 59% for Gemcis). 128 additional patients should be added in the phase III trial with an objective of overall survival improvement of 4â¯months in favor of mFOLFIRINOX. CONCLUSION: The study is opened in France (EudraCT no.: 2015-002282-35). All the patients (188) of the phase II part are currently randomized.

We report a case of metastatic pancreatic-head mucinous carcinoma (with multiple lymph node and bone metastases) and review the relevant literature. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) was useful for diagnosis, and a satisfactory outcome was achieved after systemic chemotherapy with FOLFIRINOX followed by resection of the primary lesion as conversion surgery. The patient was a 55-year-old man. Hematological findings included elevated serum tumor marker levels: CEA 12.7 ng/mL, DUPAN-2 400 U/mL. Findings from several imaging modalities and EUS-FNA confirmed a clinicopathological diagnosis of metastatic pancreatic mucinous carcinoma with multiple bone and lymph node metastases. Five courses of modified FOIFIRINOX (m-FFX) were given as systemic chemotherapy, which had an antitumor effect. Subtotal stomach-preserving pancreaticoduodenectomy and extensive lymph-node dissection were thus performed. Histopathological analysis showed invasive ductal carcinoma, muc (pT3, pN1b, cM1). After surgery, the clinical course was notable for the absence of complications. Tegafur/gimeracil/oteracil (S-1) was started as maintenance adjuvant chemotherapy postoperatively, and no disease progression has been observed at 10 months after surgery.
