Filter by:For the gastric cancer, paclitaxel is recommended as salvage standard treatment. Afatinib is a novel, potent, small ErbB family blocker that covalently binds and irreversibly blocks signaling through activated EGFR, HER2 and ErbB4 receptors, as well as the transphosphorylation of ErbB3. The investigators suggest a randomized phase II trial of afatinib plus weekly taxol(paclitaxel) for previously treated EGFR positive gastric cancer patients. The aim of current trial is to evaluate the antitumor efficacy of afatinib for target enriched patients in gastric cancer.
The incidence of malignity in the gastroesophageal junction (GEJ) is rising in Denmark, 400 new cases annually 1. 60% of the patients with GEJ cancer have disseminated disease (M1-stage) at time of diagnosis and are consequently unable to undergo curative intended surgery. The prognosis is poor, with 5-year survival rates of approximately 2 % for these 60% and the treatment only consists of palliative therapy 1. For the remaining approximately 40 % who are assessed as candidates for curative intended surgery, the 5-year survival rate is 33 % 1. This emphasizes the need for further research and knowledge concerning tumour biology and spontaneous course of the disease. In Denmark, all cancer patients are enrolled in a specific cancer program. The primary diagnostic work-up for GEJ cancers includes gastroscopy with biopsy, blood samples, ultrasonography scan, Positronemissionstomography (PET) and Computed tomography (CT) alone or PET/CT in combination 2. From these parameters physicians determine resectability and TNM-stage (tumour staging), which is substantial for the prognosis and future treatment. The primary goal is to achieve a macroscopically resection of tumour and lymphnodes in relation to the stomach and oesophagus (Esophagectomi a.m. Ivor Lewis and D1+ lymphadenectomy in the abdomen and thorax). In addition to surgery, patients receive perioperative chemotherapy, which consist of three series of chemotherapy preoperative and three series postoperative approximately 21-28 days after surgery. Approximately 12.6 % of patients receiving perioperative chemotherapy prior to surgery will have disease progression due to chemotherapy resistance during the therapy 3. This unintentionally leads to shifting these patients from the resectable group to non-resectable group (palliative treatment). Thus, the possibility for detecting response to perioperative chemotherapy is of great interest. A paradigm shift towards an individualised tailored therapy form has emerged in recent years, which potentially require a higher need for diagnosis on molecular level. Today most molecular biological methods apply tissue samples for in-vitro analyses, but new radiological tools provide opportunity for non-invasive examinations; for example PET can with a radioactive sugar compound: Flour-18 deoxyglucose (18F-FDG). This compound is injected through a catheter in a larger vein (media cubiti vein) and absorbed in cells with increased metabolism - especially cancer cells. A PET scanner registers the absorption; this radiology modality can provide valid information, which is essential for non-invasive tumour staging and monitoring response under a specific therapy. A new diagnostic modality is PET scan combinated with magnetic resonance (PET/MR) simultaneously. So far, no studies have conducted an evaluation of simultaneous PET/MR scan to assess the perioperative chemotherapy response in patients with GEJ cancer. However, some studies suggest that commercially available PET/MR scanner might contribute in a diagnostic elucidation 6. Simultaneous PET/MR scan might in theory minimize the misinterpretations of potential response changes after chemotherapy, which can appear in the interval between separate PET, CT and MR scans 4,5,7. Studies have found PET scan of GEJ cancer could be helpful as a prognostic tool to differentiate between responders and non-responders during chemotherapy 9. Standardized uptake value (SUV) is a unit that display the absorption of 18F-FDG and is used routinely to quantify tumour glucose metabolism in PET scan 8. A change of more than 35 % in SUV measurements before and after the induction of chemotherapy is considered as the definition of responders and non-responders in earlier studies 9. The MR technique is based on magnetic fields and radio waves. Diffusion Weighted Imaging (DWI) is a non-invasive MR-modality, which measures the changes in water diffusion (Brownian movements) throughout tissue. These changes are measured in Apparent Diffusion Coefficient (ADC), a parameter derived from DWI and reflects the change in diffusion 7. ADC and DWI can be used to differentiate between benign and malignant tumours, due to a larger cell density in malignant tumours. Consequently, malignant tissue has a decreased diffusion relative to normal tissue. ADC has been used as a factor in some studies to predict the response to chemotherapy 10. A single study has shown a rise in ADC-value two weeks after initiation of chemotherapy in patients with GEJ cancer, and demonstrated that the percentage change in ADC-value between the groups (responders and non-responders) is significantly different 11. Simultaneous PET- and MR scan might be very useful to evaluate the response to chemotherapy in patients with GEJ cancer compared with these parameters alone. The opportunity for a more individualised tailored treatment in future might be possible with PET/MR.
The purpose of this study is to find out whether it is better to receive a new drug, BBI608, in addition to paclitaxel chemotherapy or better to receive paclitaxel chemotherapy alone as second line treatment for gastric and gastroesophageal junction cancer after prior first line platinum and fluoropyrimidine based chemotherapy.
Background: The prevalence of gastroesophageal-junction cancer (cancer between the distal part of the oesophagus, and proximal part of the stomach/GEJ-cancer) is increasing in Denmark with more than 400 patients per year. The 5-year overall survival is less than 10% for the 2/3 of the patients, which are not considered resectable. Even for the 1/3, which is treated with surgical intervention and neoadjuvant chemotherapy the overall-survival is approximately 30%. The current Danish intended curative treatment consists of esophagectomy (surgical resection of the oesophagus with extended lymphadenectomy in abdomen and thorax (removal of lymphnodes)). Furthermore, perioperative chemotherapy consists of 6 series neoadjuvant chemotherapy (3 series before, and 3 series after operation). Unresectable patients receive palliative chemotherapy and no resection. Peritoneal washing cytology (PWC) is a recommended prediagnostic modality in gastric cancer patients. The method is used to detect free peritoneal cancer cells in the abdominal cavity even when macroscopic carcinomatosis is not present (i.e. the cancer has spread to other parts of the abdomen). Carcinomatosis can be found in up to 19% in gastric cancer patients often in the peritoneum. Positive peritoneal cytology (C1) can be identified in up to 7% of gastric cancer patients without metastases (C1M0), i.e. malignant cells can be identified in the peritoneal washing, but tumor spread has not been identified. Lots of studies indicate that C1-disease is an independent prognostic predictor for decreased survival, and increased recurrence rate, comparable with M1 patients (i.e. patients with distant metastases). The American Joint Committee on cancer recommends that C1 patients should be treated non-surgically - even when M1 disease has not been identified. On the basis of the above, PWC can be used to identify patients at greater risk for recurrence, and thereby not candidates for intended curative treatment. It is a fact, though, that C1M0 patients have a better survival than C1M1 patients. Currently, there is no level-1 evidence for specific treatment of C1M0 patients, why further research is required to approach this patient group in the most comprehensive way. The focus group of our study is therefore C1M0 patients, because of the difference in opinions. Furthermore most evidence is based on gastric carcinomas, why GEJ-cancer patients are the group, we will examine. Purpose: Peritoneal washing cytology (PWC) is performed as a standard prediagnostic modality at Rigshospitalet, for patients with gastric- and GEJ cancer, considered resectable at preceding multidisciplinary conference. Most studies in the past 20-years have focused on gastric cancer, and not specifically GEJ-cancer. This study will determine the usefulness of peritoneal washing cytology, and thereby verifying our own standard regarding GEJ-cancer. Furthermore, we will determine the effect of neoadjuvant chemotherapy on free peritoneal tumor cells and its correlation with overall survival. This study is intended as a validation of our own standard.
Patients with esophageal and gastroesophageal junction (GEJ) cancer often have weight loss, swallowing problems, and poor appetite. This may affect their ability to tolerate cancer treatment. The purpose of this study is to see if the researchers can apply a set of nutrition guidelines designed specifically for patients with cancer who are older than 65 years of age. The questions will allow them to assess the nutritional status and make appropriate referrals. If the patients are having swallowing problems or losing weight, the researchers want to address the nutritional problems early in the course of their treatment.
This study will evaluate overall survival of nimotuzumab in combination with irinotecan compared to irinotecan alone in subjects with EGFR overexpressed advanced gastric or gastroesophageal junction cancer.
To determine whether the combination of MM-111 plus paclitaxel and trastuzumab is more effective than paclitaxel and trastuzumab alone
This single-arm, open-label study will evaluate the safety and efficacy of the combination oxaliplatin, capecitabine, and trastuzumab with chemoradiotherapy in the adjuvant setting in participants with curatively resected HER2+ gastric or gastroesophageal junction cancer. Participants will receive trastuzumab 8 milligrams per kilogram (mg/kg) intravenously (IV) on Day 1 of Cycle 1 and 6 mg/kg IV on Day 1 of every following 3-week cycle, with oxaliplatin 100 milligrams per square meter (mg/m^2) IV on Day 1 of Cycles 1-3, and capecitabine 850 mg/m^2 orally twice daily on Days 1-14 of Cycles 1-3 and on 5 days per week during chemoradiotherapy. Radiotherapy will be given at a total dose of 45 gray (Gy) divided into 25 doses on 5 treatment days each week for 5 weeks starting Day 22 of Cycle 3. Anticipated time on study treatment is 1 year plus a 1-year follow-up period.
The combination of Cisplatin and S-1 (CS) achieved a response rate of approximately 45% with the PFS being around 6 months and overall survival time being 13 months in Japanese and Chinese gastric patients. It remains unclear whether the addition of docetaxel to CS would further enhance the efficacy as it dose in DCF(docetaxel, cisplatin and 5-fluorouracil). This is a single center, phase II clinical trial to evaluate the efficacy of docetaxel, cisplatin and S-1 (DCS) as first line chemotherapy for patients with advanced gastric and gastroesophageal junction cancer.
The purpose of this study is to evaluate the efficacy and safety of the combination of Cisplatin,5-Fluorouracil(5FU) and Afatinib as first-line therapy in patients with advanced gastric or gastroesophageal junction cancer. The study will include 55 patients in all. The patients will receive open-label Cisplatin intravenous 75mg/m2 on Day 1, 5FU 750mg/m2 at 24-hour intravenous infusion on Days 1-4, and Afatinib 40mg per os on Days 3-5, 8-12, 15-19. The administration of Afatinib will start on Day 3 of each therapy cycle with an administration interval on each weekend ("Weekday on, Weekend off") for 21 days. Instructions are given on the dose reduction scheme in the presence of toxicity. The administration of the combination Cisplatin-5FU-Afatinib will be continued until disease progression, appearance of significant toxicity, completion of 6 treatment cycles, or withdrawal of consent. At completion of 6 cycles of the combination, in the absence of disease progression, the administration of Afatinib as maintenance monotherapy will be continued until disease progression, appearance of significant toxicity, or withdrawal of consent at the weekday on-weekend off schedule. Imaging will be applied once every 8 weeks, and once every 12 weeks in the Afatinib maintenance therapy phase.
