Abstract
Great efforts have been made over the years to identify novel drug pairs with synergistic effects. Although numerous computational approaches have been proposed to analyze diverse types of biological big data, the pharmacogenomic profiles, presumably the most direct proxy of drug effects, have been rarely used due to the data sparsity problem. In this study, we developed a composite deep-learning-based model that predicts the drug synergy effect utilizing pharmacogenomic profiles as well as molecular properties. Graph convolutional network (GCN) was used to represent and integrate the chemical structure, genetic interactions, drug-target information, and gene expression profiles of cell lines. Insufficient amount of pharmacogenomic data, i.e., drug-induced expression profiles from the LINCS project, was resolved by augmenting the data with the predicted profiles. Our method learned and predicted the Loewe synergy score in the DrugComb database and achieved a better or comparable performance compared to other published methods in a benchmark test. We also investigated contribution of various input features, which highlighted the value of basal gene expression and pharmacogenomic profiles of each cell line. Importantly, DRSPRING (DRug Synergy PRediction by INtegrated GCN) can be applied to any drug pairs and any cell lines, greatly expanding its applicability compared to previous methods.

Xiang F, Luo F. Stem cell factor modulates HIF-1α levels and diminishes 5-FU sensitivity in 5-FU resistant pancreatic cells by altering the anabolic glucose metabolism. J Biochem Mol Toxicol 2023; 37:e23487. [PMID: 37718545 DOI: 10.1002/jbt.23487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 06/19/2023] [Accepted: 07/31/2023] [Indexed: 09/19/2023]
Abstract
Resistance to chemotherapy in cancer leads to poor therapeutic outcomes and also leads to challenges in treatment. The present work evaluated the mechanism involved in the resistance of 5-flurouracil (5-FU) in pancreatic cancer. At least 14 different pancreatic cancer (PC) cell lines were used for the study. For in vivo study female nude mice were selected. Patient-derived tumor xenograft samples were obtained from patients. The study involved, study for glucose uptake, fluorescence-activated cell sorting for glucose transporter, 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide for cell survival, Picto-micrography for clonogenic assay, glutamine uptake assay, extracellular acidification and oxygen consumption rate, carbon dioxide release assay and lactate assay were also done. In addition to this, quantitative real-time polymerase chain reaction analysis for expression of genes, chromatin immunoprecipitation assay, western blot for protein expression, and immunohistochemical analysis in tumor sections, the tumors were studied by imaging for hypoxia and localization of TKT and CTPS-2. Also, patient-derived xenograft tumors were engrafted in nude mice, followed by a glucose uptake assay. We reported that elevated glycolytic flux causes dependence on glucose in cancer cells and, at the same time, increases pyrimidine biosynthesis. It was also found that stem cell factor-mediated stabilization of hypoxia-inducible factor-1a (HIF-1α) modulates the resistance in PC. Targeting HIF-1α in combination with 5-FU, strongly reduced the tumor burden. The study concludes that stem cell factor modulates HIF-1α and decreases the sensitivity in 5-FU resistant pancreatic cancer cells by targeting glucose metabolism. Deceased expression levels of CTPS-2 and TKT, which are regulators of pyrimidine biosynthesis could better the chance of survival in patients of pancreatic cancer receiving treatment of 5-FU.

Abstract
Background and aim This investigation was aimed at disclosing whether SRPX2 affected pancreatic cancer (PC) chemoresistance by regulating PI3K/Akt/mTOR signaling. Methods Totally 243 PC patients were recruited, and they were incorporated into partial remission (PR) group, stable disease (SD) group and progressive disease (PD) group in accordance with their chemotherapeutic response. PC cell lines (i.e. AsPC1, Capan2, VFPAC-1, HPAC, PANC-1, BxPC-3 and SW1990) and human pancreatic ductal epithelial cell lines (hTERT-HPNE) were also collected. Results PC patients of SD + PD group were associated with higher post-chemotherapeutic SRPX2 level than PR group, and their post-chemotherapeutic SRPX2 level was above the pretherapeutic SRPX2 level (P < 0.05). PR population showed lower SRPX2 level after chemotherapy than before chemotherapy (P < 0.05). Besides high serum SRPX2 level and SRPX2 level change before and after chemotherapy were independent predictors of poor PC prognosis. Additionally, si-SRPX2 enhanced chemosensitivity of PC cell lines, and expressions of p-PI3K, p-AKT and p-mTOR were suppressed by si-SRPX2 (P < 0.05). IGF-1 treatment could changeover the impact of si-SRPX2 on proliferation, migration, invasion and chemoresistance of PC cells (P < 0.05). Conclusion The SRPX2-PI3K/AKT/mTOR axis could play a role in modifying progression and chemoresistance of PC cells, which might help to improve PC prognosis.

Abstract
OBJECTIVES We evaluated how well phase II trials in locally advanced and metastatic pancreatic cancer (LAMPC) meet current recommendations for trial design. METHODS We conducted a systematic review of phase II first-line treatment trial for LAMPC. We assessed baseline characteristics, type of comparison, and primary end point to examine adherence to the National Cancer Institute recommendations for trial design. RESULTS We identified 148 studies (180 treatment arms, 7505 participants). Forty-seven (32%) studies adhered to none of the 5 evaluated National Cancer Institute recommendations, 62 (42%) followed 1, 31 (21%) followed 2, and 8 (5%) followed 3 recommendations. Studies varied with respect to the proportion of patients with good performance status (range, 0%-80%) and locally advanced disease (range, 14%-100%). Eighty-two (55%) studies concluded that investigational agents should progress to phase III testing; of these, 24 (16%) had documented phase III trials. Three (8%) phase III trials demonstrated clinically meaningful improvements for investigational agents. One of 38 phase II trials that investigated biological investigational agents was enriched for a biomarker. CONCLUSIONS Phase II trials do not conform well to current recommendations for trial design in LAMPC.

Abstract
Aims and Background To evaluate the influence of radiation therapy target volume on the treatment outcome of adjuvant chemoradiotherapy for pancreatic cancer after curative resection. Methods Between February 1987 and July 2001, 70 patients treated with curative resection and adjuvant chemoradiotherapy for pancreatic adenocarcinoma were analyzed. There were 49 males and 21 females, with a median age of 57 years. Whipple's operation was performed in 44 patients, pylorus-preserving pancreaticoduodenectomy in 14, distal pancreatectomy in 9, and subtotal pancreatectomy in 3. Postoperative adjuvant radiotherapy was given up to 40 Gy at 2 Gy per fraction with a two-week planned rest. Intravenous 5-fluorouracil (500 mg/m2/day) was given on days 1 to 3 of each split course of radiotherapy. Until 1991, whole pancreas or preoperative tumor volume and retroperitoneal lymph nodes were irradiated (extended field, n = 14). Thereafter, the target volume included the retroperitoneal lymph nodes and the involved pancreatic resection margin (limited field, n = 56). The median follow-up period of all the patients was 16 months (range, 2-99). Results The overall 2- and 5-year survival rate of all patients was 29.7% and 14.0%, respectively. According to the radiotherapy target volume, the median survival time was 14 months in the extended field group and 16 months in the limited field group ( P = 0.65). Conclusions From the viewpoint of the target volume of radiotherapy, a limited field did not worsen the treatment outcome, although the survival rate was poor in both groups.

Abstract
Aim To determine the activity and toxicity of a combination of weekly gemcitabine and 5-fluorouracil bolus intravenously in patients with metastatic pancreatic cancer. Patients and methods Twenty-one patients with previously untreated metastatic pancreatic cancer were included in this phase II study. The schedule was gemcitabine (1000 mg/m2 iv) and 5-fluorouracil (500 mg/m2 bolus iv) weekly for 3 weeks every month. Results Four patients (19%) achieved a partial response and three stable disease. A clinical benefit was obtained in 7 patients (33%). Median survival for all the patients was 6 months. The treatment was well tolerated and toxicity was mild. WHO grade 3 leukopenia occurred in 2 (9.5%) patients, grade 3 anemia in 4 (19%) patients, grade 3-4 thrombocytopenia in 4 (19%) patients, grade 1 diarrhea in 1 (4.7%) patient and grade 1 mucositis in 3 (14.2%) patients. Conclusion The weekly administration of gemcitabine combined with 5-fluorouracil bolus iv is an active and well-tolerated regimen in metastatic pancreatic cancer. However, its efficacy is relatively limited.

Abstract
Prior phase III trials in advanced pancreatic cancer have been predominantly unsuccessful. In this review, we attempt to understand how past preclinical data were translated into phase III clinical trials in metastatic pancreatic cancer as described in the article. A systematic literature review conducted through the MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases, from January 1997 to June 2015 using key words-phase III clinical trials, metastatic/advanced pancreatic adenocarcinoma or pancreatic cancer identified 30 randomized controlled trials (RCTs) that met criteria. The trials were limited to RCTs in the first-line treatment of patients with metastatic pancreatic cancer. The success rate of first-line phase III studies in advanced pancreatic cancer was only 13%. In 60% of the RCTs, no preclinical experiments were referenced in biologically cognate pancreatic models. Nine (30%) of the RCTs were designed based on preclinical evidence from in vitro cell lines alone without additional in vivo validation in xenograft models. It remains uncertain how strongly the preclinical data influence the development of clinical regimens but so far the studies developed based on more solid preclinical evidence have been successful.

Abstract
In the present study, chitosan and polyvinyl alcohol (PVA) were blended with different concentrations of sodium montmorillonite (Na+MMT) clay solution by a solvent casting method. X-ray diffraction and transition electron microscope results show that the film properties are related to the co-existence of Na+MMT intercalation/exfoliation in the blend and the interaction between chitosan-PVA and Na+MMT. 5-Fluorouracil (5-FU) was loaded with chitosan-PVA/Na+MMT nanocomposite films for in vitro drug delivery study. The antimicrobial activity of the chitosan-PVA/Na+MMT films showed significant effect against Salmonella (Gram-negative) and Staphylococcus aureus (Gram-positive), whereas 5-FU encapsulated chitosan-PVA/Na+MMT bio-nanocomposite films did not show any inhibition against bacteria. Our results indicate that combination of a flexible and soft polymeric material with high drug loading ability of a hard inorganic porous material can produce improved control over degradation and drug release. It will be an economically viable method for preparation of advanced drug delivery vehicles and biodegradable implants or scaffolds.

Abstract
OBJECTIVE To evaluate the effects of long-term therapy with fosinopril, irbesartan and atenolol on the autonomic control of the cardiovascular system in hypertensive patients. METHODS We enrolled 58 patients (mean age 38 +/- 10 years) with never-treated mild hypertension with no evidence of target organ damage. The study was single blind. Patients were assigned to receive fosinopril 10-20 mg/day, irbesartan 150-300 mg/day or atenolol 50-100 mg/day for 14 weeks. Dosage was titrated to reach an average office blood pressure (BP) of <140/90mm Hg. Before therapy all patients underwent a 24-hour Holter ECG to evaluate heart rate variability (HRV) through nonlinear methods, 24-hour ambulatory BP monitoring (ABPM), and measurement of baroreflex sensitivity (BRS) using a Portaprés device; all measurements were repeated after therapy. RESULTS All three therapies significantly and equally decreased BP, both office (systolic/diastolic blood pressure 152 +/- 11/97 +/- 7mm Hg vs 129 +/- 7/85 +/- 4mm Hg after fosinopril, 151 +/- 11/97 +/- 6mm Hg vs 133 +/- 9/87 +/- 8mm Hg after irbesartan, 149 +/- 13/96 +/- 9mm Hg vs 132 +/- 9/87 +/- 7mm Hg after atenolol; p < 0.001) and ABPM values. HRV calculated with nonlinear methods and BRS were significantly increased after atenolol whereas no significant change was found in the fosinopril and irbesartan treatment groups. CONCLUSIONS All three therapies significantly and similarly reduced BP without modifying heart rate, except for atenolol, which significantly decreased it. Although angiotensin directly increases sympathetic tone, neither fosinopril nor irbesartan modified cardiovascular autonomic function; this is likely to be connected to the fairly good basal autonomic function of the population evaluated. Atenolol is associated with a significant increase in HRV and BRS probably through an improvement of parasympathetic tone.

Abstract
Background Gene-directed enzyme prodrug therapy (GDEPT) is a two-step treatment protocol for solid tumors that involves the transfer of a gene encoding a prodrug-activating enzyme followed by administration of the inactive prodrug that is subsequently activated by the enzyme to its tumor toxic form. However, the establishment of such novel treatment regimes to combat pancreatic cancer requires defined and robust animal model systems. Methods Here, we comprehensively compared six human pancreatic cancer cell lines (PaCa-44, PANC-1, MIA PaCa-2, Hs-766T, Capan-2, and BxPc-3) in subcutaneous and orthotopical mouse models as well as in their susceptibility to different GDEPTs. Results Tumor uptake was 83% to 100% in the subcutaneous model and 60% to 100% in the orthotopical mouse model, except for Hs-766T cells, which did not grow orthotopically. Pathohistological analyses of the orthotopical models revealed an infiltrative growth of almost all tumors into the pancreas; however, the different cell lines gave rise to tumors with different morphological characteristics. All of the resultant tumors were positive for MUC-1 staining indicating their origin from glandular or ductal epithelium, but revealed scattered pan-cytokeratin staining. Transfer of the cytochrome P450 and cytosine deaminase suicide gene, respectively, into the pancreatic cancer cell lines using retroviral vector technology revealed high level infectibility of these cell lines and allowed the analysis of the sensitivity of these cells to the chemotherapeutic drugs ifosfamide and 5-fluorocytosine, respectively. Conclusion These data qualify the cell lines as part of valuable in vitro and in vivo models for the use in defined preclinical studies for pancreas tumor therapy.

Abstract
Pancreatic cancer is a devastating disease with a low overall survival rate. Chemotherapy is the most common treatment for patients presenting with advanced pancreatic cancer. Gemcitabine achieves a modest improvement in overall survival and is the gold standard for advanced pancreatic cancer treatment. Capecitabine and S-1, derivatives of 5-fluorouracil (5-FU), offers minimal clinical benefits. Folfirinox represents a new and aggressive regimen that might benefit patients of metastatic pancreatic cancer with good performance status. Other chemotherapy drugs such as platinums and irinotecan do not provide significant improvement in overall survival, but have been used as part of combinational therapies. Comparing to systemically delivered chemotherapy, regional intra-arterial chemotherapy achieves higher local drug concentration in tumors with lower systemic drug toxicity, and may serve as a better treatment regimen. Although there have been progress made in chemotherapeutic strategies against pancreatic cancer, the overall survival is not significantly improved in the last decade. Recently, development of chemotherapy in combination with molecular targeted therapies holds great promise in pancreatic cancer treatment, especially in patients with metastatic disease. Growing bodies of preclinical and clinical evidences indicate that the combination of conventional modalities with specific molecular targeted therapy increase the efficacy of the monotherapy without an increase in toxicity. In this review, we summarized the current regimens of chemotherapy and molecular targeted therapy for advanced pancreatic cancer and highlighted the novel combinational treatments tested in recent clinical trials.

Abstract
The aim of the study was to evaluate the efficacy and tolerability of gemcitabine and uracil-tegafur (UFT) combination in patients with advanced pancreatic carcinoma, retrospectively. Thirty-one patients, including 27 with metastatic disease, were treated with gemcitabine at a dose of 1000 mg/m2 in 30 minutes on days 1 and 8, and oral UFT 300 mg/m2 on days 1-14, as the first-line regimen in advanced stage. The cycle was repeated every 21 days. A total of 116 cycles of chemotherapy were administered, with a median of 3 cycles per patient (range 1-13). The objective response rate was observed in 6 (19.3%) patients with 1 (3.2%) complete response, and 5 (16.1%) partial responses. The median response duration was 4 (range, 3-14) months. Eight (25.8%) patients had a standard deviation of more than 3 months. Median overall survival was 8 months (95% CI, 6-10 months) and median time to progression was 4.2 months (95% CI, 1-6 months). This combination was generally well tolerated. There were no life-threatening side effects. Most common toxicities were of hematologic and gastrointestinal nature. In conclusion, this regimen was well tolerated and seemed to have a moderate activity in the palliative treatment of advanced pancreatic carcinoma.

Abstract
BACKGROUND In an effort to improve efficacy of single-agent gemcitabine in pancreatic cancer, several studies have examined the effects of 5-FU combined with gemcitabine. However, no studies to date have been performed in Japanese patients. We thus conducted a phase I/II study of gemcitabine and infusional 5-FU in Japanese patients to determine a recommended dosage for this combination and clarify efficacy and toxicity. METHODS Phase I evaluated the frequency of dose limiting toxicity of two 5-FU dosages (400 and 500 mg/m(2)/day) infused continuously over 5 days combined with gemcitabine 1000 mg/m(2) x 3 every 4 weeks. Results from phase I determined the recommended dosage to be examined in phase II for effect on survival period, clinical benefit response (CBR), tumor response and safety. RESULTS A total of 34 chemo-naive patients were entered into the study. All had a Karnofsky performance of > or =50 points and distant metastases. Dose limiting toxicities in phase I determined the recommended 5-FU dosage at 400 mg/m(2)/day. Grade 3-4 hematological toxicities (neutropenia, leukopenia and thrombocytopenia) were the most common severe toxicities. For the 28 patients administered the recommended dosage, 1-year survival rate was 14.3%, median survival time 7.1 months and progression free survival 3.2 months. Seven patients achieved a 25% overall response rate and three showed 27.3% improvement in CBR. CONCLUSION Although a meaningful survival benefit over single-agent gemcitabine was not demonstrated, 5-FU 400 mg/m(2)/day infused continuously over 5 days in combination with gemcitabine 1000 mg/m(2) x 3 every 4 weeks appeared to be a moderately effective palliative treatment with low toxicity in Japanese patients with metastatic pancreatic cancer.

Abstract
AIM A multi-centred, open-labelled, phase 11 study containing 46 patients was conducted to evaluate the clinical benefit of gemcitabine (1,400 mg/m(2)) combined with 5-FU (3 g/m(2)) in a 48 h continuous infusion (CI). METHODS Both drugs were administered on days 1, 8 and 15 of every 4 week cycle in chemotherapy-naïve patients with locally advanced unresectable metastatic pancreatic carcinoma. The minimum follow-up was 6 months. RESULTS Clinical benefit response was the primary endpoint and this was achieved by 24.4% of the patients. Quality of life (QoL) improved in 16.6% of patients. Objective response was observed in 7% of the patients. The median progression-free survival (PFS) was 14.4 weeks and the median overall survival (OS) time was 22.7 weeks. One-year survival was 25%. The most frequent grade 3-4 toxicities were neutropenia (45%), mucositis (7.5%) and hyperbilirubinaemia (10.5%). CONCLUSIONS This schedule was not superior in terms of clinical benefit, response rate, PFS and OS than standard gemcitabine treatment

Abstract
OBJECTIVE The aim of this study was to determine the maximum-tolerated dose and dose-limiting toxicity (DLT) of combination therapy with gemcitabine and S-1 in patients with advanced pancreatic cancer. METHODS Chemotherapy-naive patients with histologically or cytologically proven unresectable or metastatic pancreatic cancer were enrolled. The patients received gemcitabine intravenously over 30 min on days 1 and 8 and S-1 orally twice daily from days 1 to 14. Cycles were repeated every 21 days until disease progression. Patients were scheduled to receive gemcitabine (mg/m(2)/week) and S-1 (mg/m(2)/day) at four dose levels: 800/60 (level 1), 1,000/60 (level 2), 1,000/70 (level 3) and 1,000/80 (level 4). RESULTS Eighteen patients were enrolled in this study. The maximum-tolerated dose was not reached even at the highest dose level (level 4) because only 2 of the 6 patients at this level experienced DLT. The DLTs were neutropenia and rash. Six (33%) of the 18 patients achieved a partial response and median overall survival time was 7.6 months. CONCLUSIONS Combination chemotherapy with gemcitabine and S-1 was well tolerated and showed good antitumor activity in the treatment of pancreatic cancer. We recommend a gemcitabine dose of 1,000 mg/m(2)/week and an S-1 dose of 80 mg/m(2)/day in further studies with this schedule.

Abstract
The objective of this study was to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of S-1, an oral fluorouracil derivative, combined with gemcitabine, the current standard treatment for advanced pancreatic cancer (APC). The subjects were histopathologically proven APC patients with distant metastasis. S-1 was administered orally twice daily each day for 14 days and gemcitabine on days 8 and 15 of each cycle, and this was repeated every 21 days. Doses of each drug were planned as follows: level 1: 800/60, level 2a: 800/80, level 2b: 1000/60, level 3: 1000/80 (gemcitabine (mg m−2)/S-1 (mg m−2 day−1)). In all, 21 patients with APC were enrolled. The main grade 3–4 toxicities observed during first cycle were neutropenia (33%), anaemia (10%), thrombocytopenia (14%) and anorexia (10%). There were no DLT observed in level 1. Three of six patients in level 2a had DLT and this level was considered the MTD. In all, 12 patients in level 2b had no DLT and this level was selected as the recommended dose. Applicable responses were one complete response and nine partial responses (48%). As toxicities were well tolerated and antitumour activities seem to be promising, this combination can be recommended for further phase II studies with APC.

Abstract
INTRODUCTION Single agent gemcitabine (GEM) is the standard treatment of pancreatic adenocarcinoma. Celecoxib is a selective cyclooxygenase-2 (COX-2) inhibitor. Recent studies in human pancreatic tumor cell lines suggest an involvement of COX-2 in tumor-dependent angiogenesis and provide the rational for inhibition of the COX pathway as an effective therapeutic approach. The aim of this study is to evaluate the toxicity and activity of gemcitabine plus celecoxib. PATIENTS AND METHODS Forty-two consecutive patients with histologically or cytologically confirmed pancreatic adenocarcinoma entered the trial. Twenty-six patients (pts) were metastatic, 16 pts had locally advanced disease. The schedule consisted of GEM 1,000 mg/m2 (as a 30 min iv infusion) on days 1, 8 every 3 weeks and celecoxib 400 mg bid. RESULTS Four pts (9%) achieved a partial response and 26 (62%) had stable disease, gaining a total disease control in 30 pts (71% [95% CI, 58-84%]). Overall clinical benefit response was experienced by 23 pts (54.7% [95%CI, 38.6-70.1%]). Neither grade 4 neutropenia nor grade 3-4 thrombocytopenia was observed. Grade 3 neutropenia was detected in 19% of pts. Grade 3 non-hematological toxicity was as follows: hepatic toxicity 7%, nausea 2.3%. Three pts (7%) and 5 pts (12%) had respectively a minimum creatinine increase and edema. Median survival was 9.1 months (95% CI, 7.5-10.6 months). CONCLUSION GEM in combination with celecoxib showed low toxicity, good clinical benefit rate and good disease control. Further clinical investigation is warranted.

Abstract
BACKGROUND In the present phase II multicenter study, we assessed the efficacy and tolerability of the combination of gemcitabine and carboplatin in patients with advanced pancreatic cancer. PATIENTS AND METHODS Patients with previously untreated, locally advanced or metastatic pancreatic cancer were treated with gemcitabine 800 mg/m(2) on days 1 and 8 and carboplatin at an AUC of 4 on day 8 of a 3-week cycle, for a total of six cycles. Primary end points were response rate and clinical benefit; secondary end points were, survival, time to progression (TTP) and toxicity. RESULTS A total of 50 patients were enrolled in the study, 47 of whom were eligible for treatment. The median age was 63 years (range 34-76) and the median Karnofsky performance status (PS) was 80%. Patients received a median of six cycles (range 1-11). Among 35 patients evaluable for response, eight (17%) achieved partial response; 15 (32%) and 12 (25%) patients had stable and progressive disease, respectively. The median overall survival was 7.4 months; the median TTP was 4.4 months and the 1-year survival was 28%. The observed clinical benefit response was remarkable. After the second cycle of chemotherapy, 21 of 31 (68%) patients experienced pain improvement and reduced analgesic consumption. At the same time, 35% and 56% of our patients significantly improved their Karnofsky PS and weight, respectively. Overall, the treatment was well tolerated. The most common grade 3-4 toxicities were hematological, including 8% anemia, 6% neutropenia and 13% thrombocytopenia. CONCLUSIONS The combination of gemcitabine plus carboplatin is a moderately active treatment for patients with locally advanced and metastatic pancreatic cancer. This regimen has an acceptable toxicity profile and provides a significant clinical benefit, and hence warrants further investigation.

Abstract
In the last decade, continued efforts in pancreas cancer research have led to the development of new, more effective therapies. Additionally, progress in understanding the molecular processes underlying the development and progression of this disease provides hope for the development of more effective treatment strategies. Recent clinical trials have provided reason for hope that novel chemotherapy combinations and molecularly targeted agents will lead to improved clinical outcomes for patients with this disease. This article will summarize the data that has led to the current standards of therapy for patients with resectable and advanced pancreatic cancer and review new treatment strategies for this disease.

Abstract
The aim of the study was to assess the response rate and toxicity of high-dose 24 h infusion of 5-fluorouracil (5FU) in metastatic adenocarcinoma of the pancreas. Patients with measurable disease, performance status 0-2, and no prior chemotherapy were registered to receive cycles of leucovorin (LV) 500 mg/m2 (or l-LV 250 mg/m2 over 1 h followed by 5FU 2.6 g/m2 over 24 h, weekly for 6 weeks, followed by a 2-week rest. The main endpoints were the response rate and toxicity. From 37 patients, 36 were the analysed for toxicity, and 33 were eligible and analysed for response. The median age was 59 years (range 28-74 years), and the median performance status was 1. Partial response was observed in three patients (9%) (95% Confidential Interval (CI): [2-24]%). Main grade 3/4 National Cancer Institute (NCI) common toxicity criteria toxicities (patients) were diarrhoea (n = 3), vomiting (n = 2) and hand-foot syndrome (n = 5). Median time to progression was 7 weeks (95% CI: [6.4-11.7] weeks) and median survival 19 weeks (95% CI: [12-35] weeks). In conclusion, high-dose 5FU and folinic acid is well tolerated, but has only modest activity in pancreatic cancer.

Abstract
AIM FOLFUGEM 1 (leucovorin 400 mg/m2 combined with 5-flurorouracil (FU) bolus 400 mg/m2 then 5-FU 2-3 g/m2/46 hours and gemcitabine 1000 mg/m2 in 30 min) in patients with locally-advanced and metastatic pancreatic adenocarcinoma appeared to be toxic (neutropenia and alopecia). The aims of this phase II multicentric study were to evaluate the response rate, clinical benefit and tolerance of a new scheme of combined leucovorin, 5-FU and gemcitabine (FOLFUGEM 2). PATIENTS AND METHODS FOLFUGEM 2 associated leucovorin 400 mg/m2 in 2 hours followed by 5-FU 1000 mg/m2 in 22 hours, then gemcitabine 800 mg/m2 (10 mg/m2/min) with cycles every 14 days. Gemcitabine dose could be increased (1000 then 1250 mg/m2) when NCI/CTC toxicity was < or = grade 2. RESULTS Fifty-eight patients were included (locally-advanced tumor: N = 13 and metastatic: N = 45). Among the 39 patients with measurable disease, 11 had partial response (28.2%, 95% confidence interval: 14-42%) and 11 had stable disease (28.2%). On an intent-to-treat analysis, the objective response rate was 19% (95% confidence interval: 9-29%). Clinical benefit rate was 46%. Median progression-free survival and median overall survival were 3.1 and 7.2 months, respectively. There were 13% grade 3-4 neutropenia and 36% complete alopecia. CONCLUSION FOLFUGEM 2 schema has an antitumoral effect in advanced pancreatic cancer and has an acceptable toxicity which appears to be less than that of FOLFUGEM 1.

Abstract
BACKGROUND A randomized phase II, open-label multicenter study evaluating oxaliplatin alone (OXA), infusional 5-fluorouracil alone (5-FU) and an oxaliplatin/infusional 5-FU combination (OXFU) in untreated, advanced pancreatic carcinoma (APC). PATIENTS AND METHODS Chemotherapy-naïve patients with advanced or metastatic, histologically/cytologically proven pancreatic carcinoma with measurable disease, received OXA [130 mg/m2, 2-h intravenous (i.v.) infusion] alone, OXA combined with 5-FU (1000 mg/m2/day, continuous i.v., days 1-4), or 5-FU alone, every 3 weeks. RESULTS Sixty-three patients (42 males/21 females) were treated: 17 patients/52 cycles OXA, 31 patients/ 175 cycles OXFU, 15 patients/41 cycles 5-FU, with a median of three, six and two cycles/patient, respectively. Patient characteristics were similar in all arms. Median age was 57 years (range 21-75), and 83% of patients had PS 0-1. Most patients (62%) had moderate to well-differentiated tumors, 90% had metastatic disease, 81% with liver metastases. All responses (three partial responses; WHO) occurred in the OXFU arm (10% response rate). Five of 32 patients evaluable for clinical benefit were responders (OXA, 14%; OXFU, 21%). Median time to progression and overall survival were higher in the combination arm (4.2 and 9.0 months, respectively) than either single-agent arm (OXA, 2.0 and 3.4 months; 5-FU, 1.5 and 2.4 months, respectively). Moderate hematotoxicity without morbidity was seen in all arms. Two OXFU patients had grade 3 oxaliplatin neurosensory toxicity. CONCLUSIONS With a 10% response rate, median overall survival of 9 months and an encouraging safety profile, the OXFU combination is effective, appears superior to infusional 5-FU and warrants further studies in APC patients.

Abstract
BACKGROUND The incidence of pancreatic cancer nearly equals its death rate (97%). Two-year survival is about 10%. Chemotherapy treatment is problematic because of the palliative and limited duration of response. MATERIAL AND METHODS The article analyzes the objective response and median survival time (MST) for old and new drugs in the treatment of pancreatic cancer. RESULTS The most encouraging results to date come from studies of 5-fluorouracil (5FU) as an adjuvant therapy and of gemcitabine in the advanced disease, which is one of the most active and best tolerated drugs in recent years. However, with the introduction of new drugs or with different old drug associations, interesting results are also becoming evident. CONCLUSIONS New approaches to CT treatment are necessary. Patient enrollment into rigorous and well conducted clinical trials, either at tumor diagnosis or after tumor recurrence, will generate new information regarding investigational therapies and it will offer improved therapies for patients with this disease.

Abstract
We report a cisplatin and irinotecan combination in patients with biopsy-proven advanced pancreatic adenocarcinoma. Patients were selected from a specialist centre and required good performance status (KPS>70%), measurable disease on CT scan, and biochemical and haematological parameters within normal limits. Based on a two-stage phase II design, we aimed to treat 22 patients initially. The study was stopped because of the death of the 19th patient during the first treatment cycle, with neutropenic sepsis and multiorgan failure. A total of 89 treatments were administered to 17 patients. Serious grade 3/4 toxicities were haematological (neutropenia) 6%, diarrhoea 6%, nausea 7% and vomiting 6%. Using the clinical benefit response (CBR) criteria, no patients had an overall CBR. For responses confirmed by CT examination, there was one partial response (5%), three stable diseases lasting greater than 6 weeks (16%), with an overall 22% with disease control (PR+SD). The median progression-free and overall survival was 3.1 months (95% CI: 1.3–3.7) and 5.0 (95% CI: 3.9–10.1) months, respectively. Although this synergistic combination has improved the response rates and survival of other solid tumours, we recommend caution when using this combination in the palliation of advanced pancreatic cancer, because of unexpected toxicity.

Abstract
Achieving substantial and meaningful improvements in the response and survival rates for advanced pancreatic cancer has proved to be an elusive goal for many years. 5-Fluorouracil (5-FU)-based chemotherapy has typically produced discouraging response rates or improved clinical benefit for patients, and attempts to improve these results by altering 5-FU dosages, administration schedules, or using a variety of drugs in combination with 5-FU have been unrewarding. A clinical benefit, however, was identified when gemcitabine first generated improvements in symptom control in patients with advanced disease. In a subsequent randomized trial, gemcitabine demonstrated superiority to 5-FU with respect to response rate, time to progression, and median survival. These improvements were also associated with improvement in clinical benefit. The findings of subsequent randomized Phase III trials have suggested a survival benefit for gemcitabine compared with several single agents or combinations. Gemcitabine has thus become the de facto standard of care for advanced pancreatic cancer, and current efforts are directed toward finding strategies that can capitalize on and extend these clinical benefits.

Abstract
Pancreatic adenocarcinoma is a common disease considered to be poorly responsive to antiblastic treatment. Recent clinical and preclinical results suggest that a combined treatment of gemcitabine (GEM), 5-flurouracil (5-FU) and folinic acid (FA) offers a clinical benefit in patients with advanced pancreas adenocarcinoma. The aim of this phase II clinical trial was to evaluate the antitumour activity and toxicity of a novel biweekly schedule of this combination in patients with pancreatic adenocarcinoma. A total of 42 patients received a 30 min infusion of FA (100 mg m(-2)) and 5-FU (400 mg m(-2)) (FUFA) on days 1-3, and GEM 1000 mg m(-2) on day 1 every 15 days. We observed 13 objective responses (two complete, 11 partial) and 23 stable diseases. The median time to progression was 9.75 months (95% Confidence Interval (CI), 6.88-12.62) and the median overall survival was 13.10 months (95% CI 9.64-16.56). There were seven cases of each grade III gastroenteric and haematological toxicity. The GEM plus FUFA combination appears to be well tolerated and very active in patients with pancreatic carcinoma.

Abstract
A number of recent clinical trials testing the combination of 5-fluorouracil (5-FU) and gemcitabine in patients with advanced pancreatic adenocarcinoma have shown a significant clinical response rate, but also significant toxicity. As the two antimetabolites may interact at several biochemical levels along their pathways of activation, we investigated whether gemcitabine (GEM) affects 5-FU pharmacokinetics in cancer patients. Thus, we compared 5-FU pharmacokinetics in two groups of patients with various cancers who received the same schedule of 5-FU and folinic acid (FUFA), with or without GEM. There was a significant increase in systemic (5-FU) exposure and toxicity in the FUFA plus GEM group. Our finding may be useful in designing future studies of the combination in order to reduce the occurrence of side-effects and to maximise the antitumour activity.

Abstract
BACKGROUND The effective treatment of unresectable pancreatic carcinoma represents a formidable challenge. There is a need to develop systemic therapies which combine efficacy with acceptable toxicity. The current 'gold standard' gemcitabine gives an objective response rate of the order of 20% and median survival up to 6 months. Here we have evaluated the efficacy and toxicity of mitomycin C, cisplatin and protracted infusional 5-fluorouracil (MCF). PATIENTS AND METHODS Forty-five patients with locally advanced (13 patients) or metastatic (32 patients) pancreatic carcinoma were treated with mitomycin C 7 mg/m(2) 6 weekly, cisplatin 60 mg/m(2) 3 weekly and protracted venous infusion 5-FU 300 mg/m(2)/day. Patients were evaluated for response after three cycles and received six cycles in total in the absence of progressive disease or poor tolerance. Median age was 62 (45-75) years; 41 patients were World Health Organization performance status 0-1. RESULTS Treatment was well tolerated with 36 (84%) patients completing three or more cycles. Grade 3 or 4 toxicities were uncommon: anaemia in three patients (7%), mucositis in two (5%), nausea and vomiting in three (7%) and diarrhoea in one (1%). An objective response was seen in 21 (46%) patients. There was one complete response. The median survival overall was 7.1 months and 10.5 months in responders. The median duration of response was 4.3 months. One-year survival was 29%, 2-year survival was 18%. CONCLUSIONS MCF combines efficacy with low toxicity in the treatment of advanced pancreatic carcinoma. The efficacy is at least comparable and may be superior to single-agent gemcitabine and MCF may therefore provide a cost-effective alternative.

Abstract
This update is devoted to discussion of optimal supportive and palliative care of patients with pancreatic cancer. Approximately 33,000 new cases of pancreatic cancer are predicted for the U.S. in 2002. Because diagnosis and intervention occur late in the course of this disease, the vast majority of patients already have metastatic disease at the time of diagnosis. These tumors are relatively resistant to systemic chemotherapy, making pancreatic cancer the fourth leading cause of cancer-related death in the U.S. and the Western world. For these reasons, efforts at identifying and treating disease-related symptomatology are priorities. This update overviews symptom management, supportive care strategies, and both standard and emerging palliative chemotherapy options. The incorporation of molecularly targeted therapies into treatment of metastatic pancreatic cancer is reviewed as well. These strategies are of relevance to internists, gastroenterologists, oncologists, and other specialists who care for patients with pancreatic cancer.

Abstract
Pancreatic cancer has one of the worst prognosis of any malignant disease. Systemic therapy is often administered because the disease is usually detected at advanced stages. Gemcitabine (Gemzar trade mark, Eli Lilly & Co.) has proven activity in the treatment of pancreatic cancer. Gemcitabine 1000 mg/m(2) was given on days 1, 8 and 15, every 4 weeks. A total of 100 chemonaive patients with locally advanced or metastatic pancreatic cancer were enrolled; 32 and 68% had stage III and IV disease, respectively. The average number of administered cycles was 3.5 (range: 1 - 12). The overall response rate was 13%, with 13 partial responders. The median time to progression was 13.5 weeks (range: 3 - 56; 95% CI = 12 - 14). The median survival was 32 weeks (range: 4 - 104; 95% CI = 27 - 36). Clinical benefit response was acheived for 26 patients (26%). Grade 3/4 haematological toxicities occurred infrequently (anaemia: 5%; neutropenia: 8% and thrombocytopenia: 3% of patients). Grade 3/4 non-haematological toxicities were not observed. There were no treatment-related deaths. Gemcitabine treatment of patients with locally advanced or metastatic pancreatic cancer is effective and well-tolerated.

Abstract
OBJECTIVE In this phase I-II study we explored the potential of the combination of weekly gemcitabine (GEM) and 24-hour continuous infusion of 5-fluorouracil (5-FU) in order to determine the toxicity profile in pancreatic cancer. The efficacy of this drug combination was studied as a secondary endpoint. METHODS Twenty-one patients with histologically or cytologically proven unresectable or metastatic previously untreated pancreatic adenocarcinoma were included in this study. Two dose levels of GEM and two dose levels of 5-FU were evaluated in three cohorts of patients who received GEM 1,000 mg/m(2) and 5-FU 2,000 mg/m(2), GEM 1,200 mg/m(2) and 5-FU 2,000 mg/m(2), or GEM 1,200 mg/m(2) and 5-FU 2,250 mg/m(2), on days 1, 8, and 15, every 4 weeks, respectively. RESULTS Grade 3-4 neutropenia was observed in 10% of the cycles. Non-myelosuppressive toxicities included fatigue (22%), grade 1-2 diarrhea (12%) and grade 1 liver toxicity. There was no limiting toxicity and the maximum tolerated dose has not been reached. Two patients experienced a partial response (9.5 +/- 12.6%) and 12 patients had stable disease (57.1 +/- 21.2%). Seven of the 14 symptomatic patients improved their disease-related symptoms and 4 of the 8 patients evaluable for clinical benefit had a clinically beneficial response (50 +/- 34.6%). The median progression-free survival was 6 months (range 2-28), median survival was 11 months (range 3-32+), and the actuarial 1-year survival rate 33%. CONCLUSION The weekly administration of GEM combined with 24-hour continuous infusion of 5-FU shows a good safety profile at the dose levels evaluated. Some partial responses had also been achieved, disregarding the dose level of the two drugs. Survival confirms the activity of this drug combination.

Abstract
BACKGROUND This phase II study was initiated to determine the activity and toxicity of a combination of gemcitabine (GEM) and cisplatin (CDDP) in patients with pancreatic cancer. PATIENTS AND METHODS CDDP 35 mg/m(2) was given as a 30-min infusion and GEM 1000 mg/m(2) as a 30-min infusion. Both drugs were administered once weekly for 2 consecutive weeks out of every 3 weeks to chemonaive patients with locally advanced or metastatic pancreatic cancer. RESULTS Forty-five advanced pancreatic cancer patients received this regimen for a total of 180 cycles of chemotherapy. One complete and four partial responses have been observed for an overall response rate of 9% (95% confidence interval 10% to 11%). Twenty-one patients (46%) had stable disease and 19 progressed on therapy. The median time to progression was 3.6 months, with a median survival of 5.6 months. A clinical benefit was obtained in nine of 37 patients (24%). Side-effects were mainly represented by hematological toxicity. Grade 3/4 WHO toxicities included neutropenia (6% of the patients) and thrombocytopenia (11%). The dose of GEM and CDDP was reduced in 14 patients (31%) and treatment was delayed in 10 patients (22%). CONCLUSIONS Our results in terms of response rate, clinical benefit and survival do not support an advantage for the combination of GEM and CDDP given by this schedule.

Abstract
PURPOSE Preclinical studies indicate positive interactions between capecitabine, an oral fluorouracil precursor, and gemcitabine, the current standard treatment for advanced pancreatic carcinoma (APC). In this study, we investigated the addition of capecitabine to gemcitabine treatment for patients with APC. PATIENTS AND METHODS This multicenter study included patients naïve to chemotherapy who had histologically or cytologically confirmed, nonresectable or metastatic pancreatic carcinoma. Gemcitabine was given at a fixed dose of 1,000 mg/m(2) on days 1 and 8 of a 21-day cycle. Capecitabine was given in increasing doses orally bid for 14 days followed by a 1-week rest. The maximum-tolerated dose (MTD) was defined as one dose level below the dose causing dose-limiting toxicity (DLT) in >or= one third of a cohort of six patients. We included an additional 15 patients at the MTD. RESULTS Thirty-six patients were included. DLT occurred at a dose of 800 mg/m(2) bid of capecitabine and consisted of myelotoxicity and mucositis. Hand-foot syndrome was not observed, and other toxic effects were mild. Thus, in this regimen, the recommended dose of capecitabine is 650 mg/m(2) bid. In 27 patients with measurable disease, we observed one complete and four partial remissions. In addition, significant drops (> 50% from baseline value) of the tumor marker CA 19-9 occurred in 14 of 24 assessable patients. CONCLUSION The combination of capecitabine and gemcitabine is well tolerated, with apparent efficacy in patients with APC. Therefore, it is currently being compared with gemcitabine monotherapy in a phase III study.

Abstract
BACKGROUND Eniluracil is a potent, irreversible inactivator of dihydropyrimidine dehydrogenase, the major catabolic enzyme for 5-fluorouracil (5-FU). Pretreatment with eniluracil significantly increases plasma half-life, plasma concentration and oral bioavailability of 5-FU. This multicenter phase II trial was designed to estimate the 6-month survival rate in patients with metastatic adenocarcinoma of the pancreas treated with 5-FU and eniluracil. PATIENTS AND METHODS One hundred and sixteen patients (61 with no prior chemotherapy and 55 with prior chemotherapy) were registered for treatment with eniluracil 50 mg (total dose) p.o. on days 1-7 and 5-FU 20 mg/m(2)/day p.o. on days 2-6 of a 28-day treatment cycle. RESULTS In 106 patients evaluable for survival, the 6-month survival rate was 34% [95% confidence interval (CI) 22% to 47%, median survival 3.6 months] for patients who had not been treated previously with chemotherapy and 29% (95% CI 16% to 42%, median survival 3.4 months) for those who had received prior chemotherapy. For those patients with measurable disease, the confirmed response rates were 8% and 2%, respectively. The most common grade 3-4 toxicities were neutropenia (29% of patients) and diarrhea (12% of patients). Overall, 69% of patients experienced a grade 3 or worse adverse event during treatment. CONCLUSIONS These results suggest that the combination of a 7-day course of eniluracil and a 5-day course of oral 5-FU has limited activity in patients with advanced pancreatic cancer, and is associated with a high frequency of clinically significant adverse events.

Abstract
Pancreatic cancer is one of the most frequently reported gastrointestinal tumors and has been reported to have a 5-year survival rate of < 5%. It is most commonly diagnosed at an advanced stage and until recently, the most frequently administered treatment for patients with advanced disease has been palliative 5-fluorouracil (5-FU)-based chemotherapy. However, in clinical trials, the novel antinucleoside gemcitabine is currently considered the standard of care and has demonstrated both a survival benefit over 5-FU and an improvement in disease-related symptoms in those patients with advanced disease. The current review presents an overview of recently completed and ongoing clinical trials of gemcitabine/5-FU combination therapy for pancreatic cancer. In these trials, the administration of 5-FU varied widely from bolus injection to 24-hour infusion to protracted infusion over several weeks. These variations make a definitive judgment of this combination difficult, especially because the majority of the data represent only Phase I and Phase II study results. Although a recently completed randomized Phase III trial of gemcitabine plus bolus 5-FU versus gemcitabine failed to show a clinically meaningful survival benefit for the combination arm, current data indicate that other gemcitabine/5-FU combinations might provide a therapeutic advantage over gemcitabine alone. However, the results of ongoing Phase III studies must be reviewed before a definitive statement can be made regarding the value of this combination in the treatment of pancreatic cancer.

Abstract
PURPOSE Gemcitabine is generally considered to constitute first-line therapy for pancreatic cancer. To determine whether the addition of fluorouracil (5-FU) improves on the results from single-agent gemcitabine, the Eastern Cooperative Oncology Group (ECOG) compared gemcitabine plus bolus 5-FU with gemcitabine alone for patients with advanced pancreatic carcinoma. PATIENTS AND METHODS This trial involved patients with biopsy-proven, advanced carcinoma of the pancreas not amenable to surgical resection. Patients were randomized to receive either gemcitabine alone (1,000 mg/m(2)/wk) weekly for 3 weeks of every 4 or to receive gemcitabine (1,000 mg/m(2)/wk) followed by 5-FU (600 mg/m(2)/wk) weekly on the same schedule. The primary end point of the trial was survival, with secondary end points of time to progression and response rate. RESULTS Of 327 patients enrolled over 18 months, 322 were eligible. Overall, the median survival was 5.4 months for gemcitabine alone and 6.7 months for gemcitabine plus 5-FU (P =.09). Progression-free survival for gemcitabine alone was 2.2 months, compared with 3.4 months for gemcitabine plus 5-FU (P =.022). Objective responses were uncommon and were observed in only 5.6% of patients treated with gemcitabine and 6.9% of patients treated with gemcitabine plus 5-FU. Most toxicities were hematologic or gastrointestinal; no significant differences were noted between the two treatment arms. CONCLUSION 5-FU, administered in conjunction with gemcitabine, did not improve the median survival of patients with advanced pancreatic carcinoma compared with single-agent gemcitabine. Further studies with other combinations of gemcitabine and 5-FU are not compelling, and clinical trial resources should address other combinations and novel agents.

Abstract
Pancreatic cancer is the fifth most common cause of cancer death in the western world and the prognosis for unresectable disease remains poor. Recent advances in conventional chemotherapy and the development of novel 'molecular' treatment strategies with different toxicity profiles warrant investigation as combination treatment strategies. This randomised study in pancreatic cancer compares marimastat (orally administered matrix metalloproteinase inhibitor) in combination with gemcitabine to gemcitabine alone. Two hundred and thirty-nine patients with unresectable pancreatic cancer were randomised to receive gemcitabine (1000 mg m(-2)) in combination with either marimastat or placebo. The primary end-point was survival. Objective tumour response and duration of response, time to treatment failure and disease progression, quality of life and safety were also assessed. There was no significant difference in survival between gemcitabine and marimastat and gemcitabine and placebo (P=0.95 log-rank test). Median survival times were 165.5 and 164 days and 1-year survival was 18% and 17% respectively. There were no significant differences in overall response rates (11 and 16% respectively), progression-free survival (P=0.68 log-rank test) or time to treatment failure (P=0.70 log-rank test) between the treatment arms. The gemcitabine and marimastat combination was well tolerated with only 2.5% of patients withdrawn due to presumed marimastat toxicity. Grade 3 or 4 musculoskeletal toxicities were reported in only 4% of the marimastat treated patients, although 59% of marimastat treated patients reported some musculoskeletal events. The results of this study provide no evidence to support a combination of marimastat with gemcitabine in patients with advanced pancreatic cancer. The combination of marimastat with gemcitabine was well tolerated. Further studies of marimastat as a maintenance treatment following a response or stable disease on gemcitabine may be justified.

Abstract
A phase I study was carried out to determine the optimal dose and administration schedule for combined UFT plus gemcitabine therapy in patients with non-small cell lung cancer. Twenty-four patients (including 11 patients previously treated with cisplatin as the key drug) received oral UFT 400 mg x m(-2) on days 1 to 14 with intravenous infusions of gemcitabine (800 mg x m(-2) on days 8 and 15, or 900 mg x m(-2) on days 8 and 15, or 900 mg x m(-2) on days 1, 8 and 15). The most appropriate dosing option appeared to be 400 mg x m(-2) per day of oral UFT for 14 consecutive days with 900 mg x m(-2) gemcitabine on days 8 and 15. Eight of the 24 patients achieved partial response. The combination chemotherapy UFT and gemcitabine was well tolerated and may benefit patients with advanced non-small cell lung cancer. A multicentre phase II study using a 3-weekly regimen is in progress.

Abstract
Gemcitabine has become a new standard for treatment of advanced pancreatic cancer. This development is based not only on drug efficacy but also on a favorable side-effect profile. Combinations of gemcitabine with antitumor drugs such as cisplatin, 5-fluorouracil, docetaxel, irinotecan, oxaliplatin, or capecitabine, and biological agents such as cetuximab or trastuzumab, have yielded promising results in phase II trials. However, none of these combinations has yet reached the level of an evidence-based standard treatment.

Abstract
BACKGROUND A prospective, randomized Phase III trial was performed to determine whether, compared with gemcitabine (GEM) alone, the addition of cisplatin (CDDP) to GEM was able to improve the time to disease progression and the clinical benefit rate in patients with advanced pancreatic adenocarcinoma. The objective response rate, overall survival rate, and toxicity patterns of patients in the two treatment arms were evaluated as secondary end points. METHODS Patients with measurable, locally advanced and/or metastatic pancreatic adenocarcinoma were randomized to receive GEM (Arm A) or a combination of GEM and CDDP (Arm B). In Arm A, a dose of 1000 mg/m(2) GEM per week was administered for 7 consecutive weeks, and, after a 2-week rest, treatment was resumed on Days 1, 8, and 15 of a 28-day cycle for 2 cycles. In Arm B, CDDP was given at a dose of 25 mg/m(2) per week 1 hour before GEM at the same dose that was used in Arm A. On Day 22, only GEM was administered. Patients were restaged after the first 7 weeks of therapy and then again after the other 2 cycles. RESULTS A total of 107 patients entered the trial: Fifty-four patients were randomized to Arm A, and 53 patients were randomized to Arm B. The median time to disease progression was 8 weeks in Arm A and 20 weeks in Arm B; this difference was statistically significant (P = 0.048). In Arm A, one complete response and four partial responses were recorded on the basis of an intent-to-treat analysis, with an overall response rate of 9.2% (95% confidence interval [95%CI], 3-20%). In Arm B, there were no complete responses, whereas 14 partial responses were achieved, with an overall response rate of 26.4% (95%CI, 15-40%). This difference in the overall response rates was statistically significant (P = 0.02). The tumor growth control rate (i.e., total number of patients who achieved complete responses, partial responses, and stable disease) was 42.6% (95%CI, 29-57%) in Arm A and 56.6% (95%CI, 42-70%) in Arm B. A clinical benefit was observed in 21 of 43 patients (49%) in Arm A and in 20 of 38 patients (52.6%) in Arm B without any significant difference. The median overall survival was 20 weeks for patients in Arm A and 30 weeks for patients in Arm B (P = 0.43). Toxicity was mild in both treatment arms, with no significant differences between the two groups except for the statistically higher incidence of Grade 1-2 asthenia in Arm B (P = 0.046). CONCLUSIONS The addition of CDDP to GEM significantly improved the median time to disease progression and the overall response rate compared with GEM alone. The clinical benefit rate was similar in both arms, whereas the median overall survival rate was more favorable for Arm B, although the difference did not attain statistical significance. The authors conclude that the combination of CDDP and GEM currently may be considered as an optimal treatment for patients with locally advanced and/or metastatic adenocarcinoma of the pancreas.

Abstract
PURPOSE Based on preclinical in vitro synergy data, this study evaluated the activity and toxicity of a gemcitabine/oxaliplatin combination in patients with metastatic and locally advanced pancreatic adenocarcinoma. PATIENTS AND METHODS Previously untreated metastatic and locally advanced unresectable pancreatic adenocarcinoma patients were enrolled onto this multicenter phase II study. Patients received gemcitabine 1,000 mg/m(2) as a 10-mg/m(2)/min infusion on day 1 and oxaliplatin 100 mg/m(2) as a 2-hour infusion on day 2 every 2 weeks. Patients with metastatic disease were treated until evidence of progressive disease, whereas patients with locally advanced disease received six cycles in the absence of progression, followed when appropriate by concomitant radiochemotherapy. RESULTS Among 64 eligible patients included in eight centers, 30 had locally advanced and 34 had metastatic disease. Response rate for the 62 patients with measurable disease was 30.6% (95% confidence interval, 19.7% to 42.3%), 31.0% for locally advanced and 30.3% for metastatic patients. Among 58 assessable patients, 40% had clinical benefit. Median progression-free survival and median overall survival (OS) were 5.3 and 9.2 months, respectively, with 36% of patients alive at 1 year. Median OS for patients with metastatic disease and locally advanced disease were 8.7 and 11.5 months, respectively. With 574 treatment cycles (median per patient, nine; range, zero to 27), grade 3/4 toxicity per patient was 11% for neutropenia and thrombocytopenia, 14% for nausea or vomiting, 6.2% for diarrhea, and 11% for peripheral neuropathy, with no toxic deaths. CONCLUSION Palliative effects, response rate, and survival observed with this well-tolerated gemcitabine/oxaliplatin combination deserve additional evaluation. A comparative study of combination therapy versus gemcitabine alone is ongoing.

Abstract
Since the introduction of gemcitabine (Gemzar; Eli Lilly and Company, Indianapolis, IN), pancreatic cancer may no longer be regarded as a completely chemotherapy-resistant tumor. Good treatment tolerability and a low incidence of side effects are clear advantages of single-agent gemcitabine and enable its integration into combination regimens. Currently, the most widely used regimens involve combination partners such as 5-fluorouracil (5-FU), cisplatin, and docetaxel. Combinations of gemcitabine with cisplatin or 5-FU appear comparably active and tolerable. Comparative analysis of multiple phase II studies performed with gemcitabine/cisplatin showed response rates in the range of 11.4% to 58% and median survival times of 7.4 to 10 months, whereas various gemcitabine/5-FU-based regimens achieved response rates of 3.7% to 25% and median survival times of 4.4 to 10.3 months. In view of the great variety of schedules and inconclusive treatment results, an optimal regimen for the combination of 5-FU and gemcitabine still needs to be defined. Although the combination of gemcitabine with docetaxel has demonstrated activity, data showing a clear survival benefit are not yet available. It is also premature to evaluate the activity of combinations with irinotecan or oxaliplatin. Four-drug regimens indicate a possible improvement in treatment outcome. However, their application may be limited to selected patients with good performance status.

Abstract
BACKGROUND Patients with metastatic pancreatic carcinoma have a poor survival. Chemotherapy with gemcitabine is the standard first-line treatment. In a Phase II trial at one academic cancer center, the clinical safety and activity of combining gemcitabine and docetaxel were assessed. METHODS Patients with previously untreated, advanced pancreatic carcinoma were eligible. Bidimensionally measurable disease or evaluable disease with an elevated tumor marker, good performance status, and adequate organ function were required. Patients received docetaxel 60 mg/m(2) on Day 1 and gemcitabine 600 mg/m(2) on Days 1, 8, and 15 every 28 days. Ciprofloxacin was administered on Days 8-18. Dose attenuations were made as indicated for toxicity. Patients were restaged radiographically after every two cycles. RESULTS Thirty-four patients were enrolled, and 33 patients were evaluable for response. There were 23 men and 10 women among the evaluable patients. The median age was 63 years, and all patients had an Eastern Cooperative Oncology Group performance status of 0 or 1. Three patients had received prior chemoradiation for postresection adjuvant therapy. One hundred forty-six cycles of chemotherapy were administered, and 5 cycles (3%) in 4 patients (12%) were complicated by febrile neutropenia. Twenty percent and 11% of patients on Day 8 and Day 15 doses of gemcitabine, respectively, were omitted for toxicity. The objective response rate was 18%, and the median survival was 8.9 months (95% confidence interval, 5.2-11.2 months). The 1-year survival rate was 29%. CONCLUSIONS The combination of gemcitabine and docetaxel in patients with advanced pancreatic carcinoma is well tolerated and is associated with moderate activity despite aggressive dose reduction. Whether combination regimens are more effective than single agents in the treatment of patients with pancreatic carcinoma awaits evaluation in randomized studies.

Abstract
BACKGROUND Pancreatic carcinoma is considered among the most chemoresistant of human malignancies. The most commonly used cytotoxic single agents, 5-fluorouracil and 2'-deoxy-2',2'-difluorocytidine (gemcitabine), have objective response rates of less than 10% in large studies. Hypothesizing noncross resistance and a synergistic interaction between gemcitabine and cisplatin, early clinical studies have demonstrated significant activity with this combination in patients with several types of malignant disease. A Phase II study was undertaken to determine the efficacy of gemcitabine in combination with cisplatin in patients with locally advanced and metastatic pancreatic carcinoma based on these considerations. METHODS The eligibility criteria included histologically confirmed, locally advanced, unresectable or metastatic exocrine carcinoma of the pancreas with no prior gemcitabine therapy; prior adjuvant therapy was allowed provided the last day of therapy was at least 6 months prior to starting treatment; clinically measurable or evaluable disease; a Southwest Oncology Group scale performance status of 0-2; a life expectancy of > 12 weeks; and adequate bone marrow, hepatic, and renal function. A total of 42 patients, 4 patients with locally advanced, unresectable disease and 38 patients with metastatic disease, were treated and received a total of 211 cycles of therapy between May 1997 to March 1999. The median age of patients was 61.5 years. The patients were treated in the outpatient setting with a combination of gemcitabine 1,000 mg/M(2) intravenously over 30 minutes administered on Days 1, 8, and 15 of each cycle and cisplatin 50 mg/M(2) intravenously administered after gemcitabine infusion on Days 1 and 15 with adequate prehydration accompanied by adequate urinary output. Cycles were repeated every 28 days. Response and toxicity were assessed according to World Health Organization and standard criteria. RESULTS The complete and partial response rate among all 42 registered patients was 11 of 42 patients (26%; 95% confidence interval, 0.14-0.42). Stabilization of disease was seen in 15 patients (38%). Two additional patients with metastatic disease who achieved major responses to chemotherapy were rendered free of disease surgically, achieving a complete response status. The median overall survival was 7.1 months (95% confidence interval [CI], 6.3-9.1 months), with 64% of patients alive at 6 months and 19% of patients alive at 12 months. The median time to disease progression was 5.4 months (range, 0.9-20.8 months). Major toxicities were neutropenia and thrombocytopenia, with one episode of neutropenic fever. CONCLUSIONS The combination of gemcitabine and cisplatin appeared to have significantly greater activity than single-agent gemcitabine in this Phase II study, with tolerable toxicity. The antitumor activity of this combination needs to be confirmed in multi-institutional or comparative trials.
