Through a prospective clinical sequencing program for advanced cancers, four index cases were identified which harbor gene rearrangements of FGFR2, including patients with cholangiocarcinoma, breast cancer, and prostate cancer. After extending our assessment of FGFR rearrangements across multiple tumor cohorts, we identified additional FGFR fusions with intact kinase domains in lung squamous cell cancer, bladder cancer, thyroid cancer, oral cancer, glioblastoma, and head and neck squamous cell cancer. All FGFR fusion partners tested exhibit oligomerization capability, suggesting a shared mode of kinase activation. Overexpression of FGFR fusion proteins induced cell proliferation. Two bladder cancer cell lines that harbor FGFR3 fusion proteins exhibited enhanced susceptibility to pharmacologic inhibition in vitro and in vivo. Because of the combinatorial possibilities of FGFR family fusion to a variety of oligomerization partners, clinical sequencing efforts, which incorporate transcriptome analysis for gene fusions, are poised to identify rare, targetable FGFR fusions across diverse cancer types.

PURPOSE The primary objective of this phase I trial was to determine the maximum-tolerated dose of radiation that could be delivered to the primary tumor concurrent with full-dose gemcitabine in patients with advanced pancreatic cancer. PATIENTS AND METHODS Thirty seven patients with unresectable (n = 34) or incompletely resected pancreatic cancer (n = 3) were treated. Gemcitabine was administered as a 30-minute intravenous infusion at a dose of 1,000 mg/m(2) on days 1, 8, and 15 of a 28-day cycle. Radiation therapy was initiated on day 1 and directed at the primary tumor alone, without prophylactic nodal coverage. The starting radiation dose was 24 Gy in 1.6-Gy fractions. Escalation was achieved by increasing the fraction size in increments of 0.2 Gy, keeping the duration of radiation constant at 3 weeks. A second cycle of gemcitabine alone was intended after a 1-week rest. RESULTS Two of six assessable patients experienced dose-limiting toxicity at the final planned dose level of the trial (42 Gy in 2.8-Gy fractions), one with grade 4 vomiting and one with gastric/duodenal ulceration. Two additional patients at this dose level experienced late gastrointestinal toxicity that required surgical management. CONCLUSION The final dose investigated (42 Gy) is not recommended for further study considering the occurrence of both acute and late toxicity. However, a phase II trial of this novel gemcitabine-based chemoradiotherapy approach, at a radiation dose of 36 Gy in 2.4-Gy fractions, is recommended on the basis of tolerance, patterns of failure, and survival data.

BackgroundWe report the results of a multi-institutional phase II trial that used preoperative full-dose gemcitabine and radiotherapy for patients with potentially resectable pancreatic carcinoma.MethodsPatients were treated before surgery with three cycles of full-dose gemcitabine (1000 mg/m2 intravenously), with radiation during the second cycle (36 Gy in daily 2.4-Gy fractions). Patients underwent surgery 4 to 6 weeks after the last gemcitabine infusion.ResultsThere were 10 men and 10 women, with a median age of 58 years (range, 50–80 years). Nineteen patients (95%) completed therapy without interruption, and one experienced grade 3 gastrointestinal toxicity. The mean weight loss after therapy was 4.0%. Of 20 patients taken to surgery, 17 (85%) underwent resections (16 pancreaticoduodenectomies and 1 distal pancreatectomy). The complication rate was 24%, with an average length of stay of 13.5 days. There were no operative deaths. Pathologic analysis revealed clear margins in 16 (94%) of 17 and uninvolved lymph nodes in 11 (65%) of 17 specimens. One specimen contained no residual tumor, and three specimens revealed only microscopic foci of residual disease. With a median follow-up of 18 months, 7 (41%) of the 17 patients with resected disease are alive with no recurrence, 3 (18%) are alive with distant metastases, and 7 (41%) have died.ConclusionsPreoperative gemcitabine/radiotherapy is well tolerated and safe when delivered in a multi-institutional setting. This protocol had a high rate of subsequent resection, with acceptable morbidity. The high rate of negative margins and uninvolved nodes suggests a significant tumor response. Preliminary survival data are encouraging. This regimen should be considered in future neoadjuvant trials for pancreatic cancer.

PURPOSE A recent report of the combination of gemcitabine and docetaxel described favorable results in patients with uterine leiomyosarcoma. The objective of this report is to describe experience with this combination in a variety of histologic subtypes of sarcoma. Additionally, cell-culture studies were performed to assess the effect of the sequence of drug administration on colony formation. PATIENTS AND METHODS A medical record review of 35 patients receiving the gemcitabine/docetaxel combination was undertaken. Gemcitabine 675 mg/m(2) intravenously was administered over 90 minutes on days 1 and 8, and docetaxel 100 mg/m(2) intravenously was administered over 60 minutes on day 8 of a 21-day cycle. Cell culture studies using the SAOS-2 osteosarcoma cell line and MCF-7 breast cancer cell line were also performed. Gemcitabine and docetaxel were added to cells either simultaneously for 24 hours, gemcitabine for 24 hours followed by docetaxel for 24 hours, or the reverse sequence. RESULTS Thirty-five patients were treated. Five complete responses and 10 partial responses were observed for an overall response rate of 43%. Responses occurred in uterine, extremity, and retroperitoneal leiomyosarcoma, osteosarcomas, angiosarcomas, malignant fibrous histiocytomas, malignant peripheral-nerve sheath tumors, and Ewings sarcoma. In the cell culture studies, gemcitabine followed by docetaxel provided synergy. In contrast, the administration of drugs simultaneously resulted in antagonism, and docetaxel followed by gemcitabine provided mixed results. CONCLUSION The combination of gemcitabine and docetaxel seems to be active in a variety of sarcomas. A multicenter, randomized clinical trial in soft tissue sarcoma comparing gemcitabine alone with this combination, is ongoing.

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.

Objectives: CI-994 (N-acetyl dinaline, PD123654) is a novel oral agent active in a broad variety ofmurine and human tumor xenografts. While cytotoxic in theBrown Norway (BN) rat leukemia model, growth inhibition inother murine and human tumor xenografts is predominantlycytostatic. Its specific mechanism of action remains unknown.Following CI-994 administration, inhibition of both histonedeacetylation and cellular proliferation at the G1 to Stransition phase of the cell cycle are observed. This Phase 1study in patients with solid tumors was carried out todetermine a maximum tolerated daily oral dose (MTD) for CI-994administered on a chronic basis. Methods: Fifty-threepatients received CI-994 daily for treatment durations rangingfrom 2 to 10 weeks. Dosage escalation proceeded in 2 phases;an Acute Dosing Phase (n = 11) to define the MTD for CI-994administered over 2 weeks and a Chronic Dosing Phase (n = 29)to define the MTD for daily administration for 8 weeks. Uponcompletion of the Chronic Dosing Phase, a third cohort ofpatients (n = 13) received CI-994 at the recommended Phase 2dose and schedule with 2 additional single doses of drugadministered separated by a 1-week washout to assess theeffect of food on CI-994 pharmacokinetics. Results:Thrombocytopenia was dose limiting at the MTD of 8mg/m2/day for 8 weeks. Other toxicities includedfatigue and gastrointestinal effects such as nausea, vomiting,diarrhea, constipation and mucositis. Pharmacokinetic studiesrevealed that peak plasma levels and AUCs generally increasedwith dose and that food intake did not affect the rate orextent of drug absorption. One patient with heavilypre-treated adenocarcinoma of the lung achieved a PartialResponse (PR) lasting over 2 years and 3 additional patientsachieved Stable Disease (SD), 1 each with non-small cell lung,colorectal, and renal cancer. Conclusions: Therecommended Phase 2 starting dose is 8 mg/m2/dayfor 8 weeks repeated after a 2-week drug-freeinterval.

PURPOSE Gemcitabine is effective in the treatment of pancreatic cancer and is a potent radiosensitizer. This study assessed safety and efficacy of full-dose gemcitabine administered before and during concurrent three-dimensional conformal radiation (3D-CRT) in patients with nonmetastatic pancreatic cancer. PATIENTS AND METHODS During cycles 1 and 3, patients received gemcitabine at 1,000 mg/m(2) on days 1 and 8 of each 21-day cycle. Cycle 2 included the same dose of gemcitabine on days 1, 8, and 15 of a 28-day cycle with concurrent 3D-CRT at 36 Gy, administered in 15 fractions of 2.4 Gy, over 3 weeks. Resectable patients underwent surgery 4 to 6 weeks after treatment. The primary objective was evaluation of toxicity. Tumor response, CA 19-9, and 1-year survival were also assessed. RESULTS Forty-one patients enrolled at six institutions between April 2002 and October 2003. Among the 39 treated patients, the most common toxicities were grade 3 neutropenia (12.8%), grade 3 nausea (10.3%), and grade 3 vomiting (10.3%). The response rate was 5.1% and disease control rate was 84.6%. Mean post-treatment CA 19-9 levels (228 +/- 347 U/mL) were significantly (P = .006) reduced compared with pretreatment levels (1,241 +/- 2,124 U/mL). Thirteen (81%) of 16 patients initially judged resectable, three (33%) of nine borderline-resectable patients, and one (7%) of 14 unresectable patients underwent resection after therapy. One-year survival rates were 73% for all patients, 94% for resectable patients, 76% for borderline-resectable patients, and 47% for unresectable patients. CONCLUSION Full-dose gemcitabine with concurrent radiotherapy was well tolerated and active. Evaluation of this regimen in a larger, randomized trial for patients with resectable or borderline-resectable disease may be warranted.

PURPOSE Local failure in unresectable pancreatic cancer may contribute to death. We hypothesized that intensification of local therapy would improve local control and survival. The objectives were to determine the maximum tolerated radiation dose delivered by intensity modulated radiation with fixed-dose rate gemcitabine (FDR-G), freedom from local progression (FFLP), and overall survival (OS). METHODS AND MATERIALS Eligibility included pathologic confirmation of adenocarcinoma, radiographically unresectable, performance status of 0-2, absolute neutrophil count of ≥ 1,500/mm(3), platelets ≥ 100,000/mm(3), creatinine <2 mg/dL, bilirubin <3 mg/dL, and alanine aminotransferase/aspartate aminotransferase ≤ 2.5 × upper limit of normal. FDR-G (1000 mg/m(2)/100 min intravenously) was given on days -22 and -15, 1, 8, 22, and 29. Intensity modulated radiation started on day 1. Dose levels were escalated from 50-60 Gy in 25 fractions. Dose-limiting toxicity was defined as gastrointestinal toxicity grade (G) ≥ 3, neutropenic fever, or deterioration in performance status to ≥ 3 between day 1 and 126. Dose level was assigned using TITE-CRM (Time-to-Event Continual Reassessment Method) with the target dose-limiting toxicity (DLT) rate set to 0.25. RESULTS Fifty patients were accrued. DLTs were observed in 11 patients: G3/4 anorexia, nausea, vomiting, and/or dehydration (7); duodenal bleed (3); duodenal perforation (1). The recommended dose is 55 Gy, producing a probability of DLT of 0.24. The 2-year FFLP is 59% (95% confidence interval [CI]: 32-79). Median and 2-year overall survival are 14.8 months (95% CI: 12.6-22.2) and 30% (95% CI 17-45). Twelve patients underwent resection (10 R0, 2 R1) and survived a median of 32 months. CONCLUSIONS High-dose radiation therapy with concurrent FDR-G can be delivered safely. The encouraging efficacy data suggest that outcome may be improved in unresectable patients through intensification of local therapy.

The combination of gemcitabine with concurrent radiation therapy (Gem/RT) is a promising new approach that is being investigated in patients with unresectable pancreatic cancer. However, substantial toxicity with this combination has also been observed. This review was conducted to determine whether Gem/RT could be safely delivered in the neoadjuvant setting, based on our experience with this combined therapy in a cohort of patients with previously unresectable pancreatic cancer, who subsequently underwent surgical resection. Between July 1996 and June 2001, a total of 67 patients with locally unresectable pancreatic cancer, without distant metastatic disease, received Gem/RT at our institution. Seventeen patients (25%) underwent exploratory surgery following Gem/RT, and nine underwent standard Whipple resection. Thus 9 (52%) of 17 patients who had exploratory operations or 9 (13%) of 67 patients, underwent surgical resection. Thirty-day mortality after resection was 0%, and there were no major surgical complications. Median length of hospital stay was 14 days (range 11 to 19 days). With a median follow-up of 32 months, median survival for the resected patients was 17.6 months (95% confidence interval 12.6 to 37.3 months). Median survival for the remaining 58 patients was 11.9 months (95% confidence interval 9.6 to 14.7 months, P = 0.013). We conclude that surgical resection may be safely performed after Gem/RT in a select group of patients initially considered to have unresectable pancreatic cancer. The use of Gem/RT in a neoadjuvant setting is currently being investigated in a multi-institutional phase II trial.

BACKGROUND Bevacizumab has demonstrated antitumor activity in multiple diseases. This phase II study was undertaken to determine the effects of adding bevacizumab to a regimen of docetaxel and oxaliplatin in patients with advanced adenocarcinoma of the stomach or gastroesophageal junction. PATIENTS AND METHODS Previously untreated patients with locally advanced or metastatic disease and a performance status (PS) of 0-1 were eligible for this study. Patients received bevacizumab at 7.5 mg/kg, docetaxel at 70 mg/m(2), and oxaliplatin at 75 mg/m(2) administered on day 1 of a 21-day cycle. The primary end point of the study was progression-free survival (PFS). RESULTS A total of 38 eligible patients (median age 57 years, 45% gastric, 55% PS 0) were enrolled on to the study. Median PFS was 6.6 months [95% confidence interval (CI) 4.4-10.5] and median survival 11.1 months (95% CI 8.2-15.3). Complete responses were documented in 2 (5%) patients, partial responses in 14 (37%), and stable disease in 14 (37%). No treatment-related deaths were observed. The most commonly reported grade 3-4 toxicity was neutropenia (34%), and gastrointestinal perforation occurred in three patients (8%). CONCLUSION The combination of bevacizumab, docetaxel, and oxaliplatin has promising activity for further evaluation in randomized trials.
