Title: Chemotherapy With or Without Preventive Anticoagulation for Metastatic Cancer of the Pancreas
Brief Summary: RATIONALE: Drugs used in chemotherapy, such as gemcitabine and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Anticoagulants, such as dalteparin, may help prevent blood clots from forming in patients being treated with chemotherapy. It is not yet known whether gemcitabine is more effective when given alone or together with dalteparin and/or capecitabine in treating patients with pancreatic cancer.

PURPOSE: This randomized phase III trial is studying whether dalteparin prevents blood clots in patients with pancreatic cancer receiving treatment with different combinations of gemcitabine and capecitabine.


Options:
A: Inclusion Criteria:

* Histologically confirmed malignancy that is metastatic or unresectable and for which standard curative therapies do not exist. Eligible malignancies include:

  * Adenocarcinoma of the pancreas (locally advanced or metastatic)
  * Colorectal (stage IV)
  * Non-small cell lung (unresectable stage III or IV)
  * Relapsed ovarian or stage IV
  * Surgically unresectable or metastatic gastric adenocarcinoma
* First or second line therapy (within 4 weeks of initiating therapy).
* Minimum age 18 years
* Life expectancy of greater than 6 months
* ECOG Performance Status 0, 1, or 2 (Karnofsky 60% or greater).
* Participants must have normal organ and marrow function as outlined in the protocol.

Exclusion Criteria:

* Participants may not be receiving any other study agents.
* Known brain metastases should be excluded from this clinical trial because of their poor prognosis and higher potential for intracranial hemorrhage.
* Prior history of documented venous thromboembolic event or pulmonary embolism within the last 5 years years (excluding central line associated events whereby patients completed anticoagulation \> 3 months previously)
* Active bleeding or high risk for bleeding (e.g. known acute gastrointestinal ulcer)
* Any history of significant hemorrhage (requiring hospitalization or transfusion) outside of a surgical setting within the last 5 years
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to enoxaparin or heparin.
* History of heparin-induced thrombocytopenia
* Presence of coagulopathy (PT or PTT\> 1.5 x upper limit of normal)
* Familial bleeding diathesis
* Known diagnosis of disseminated intravascular coagulation
* Currently receiving anticoagulant therapy
* Current use of aspirin (\>81mg daily), Clopidogrel (Plavix), cilostazol (Pletal), aspirin-dipyridamole (Aggrenox), or regular use of non-steroidal anti-inflammatory agents more than twice weekly. Maximum dose of ibuprofen is 400mg no more than twice per week.
* Uncontrolled intercurrent illness including, but not limited to, ongoing active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

C: Inclusion Criteria:

Patients with completely resected non-small cell lung cancer of stage I, II, or IIIA T3N1 confirmed by histology can be included in the study Patients who had preoperative chemotherapy, those who are selected for adjuvant chemotherapy and those who are not candidates for adjuvant chemotherapy (because they have a contraindication to chemotherapy or they have a stage I cancer) are eligible for the study Written informed consent age \> 18 years

Exclusion Criteria:

Previous heparin induced thrombocytopenia Allergy to tinzaparin Allergy to sulfites Renal failure with a creatinin clearance \< 30 ml/min according to COCKROFT formula Prothrombin time \< 50% Platelet count \< 100 G/L Increased bleeding risk: ongoing hemorrhage, major bleeding within 10 days, previous intracerebral bleeding, uncontrolled hypertension (SAP \> 180 mmHg or DAP \> 120 mmHg) Indication for curative anticoagulant treatment on inclusion More than 6 weeks between surgery and inclusion Known pregnancy or no efficient contraception for women of childbearing age Breast feeding Previous malignant disease diagnosed within 2 years except in situ carcinoma of the uterine cervix or spinal-cellular or baso-cellular cutaneous carcinoma Inclusion in another therapeutic trial at the time of inclusion Treatment with an experimental drug within 30 days before inclusion in the study
