Active Comparator: Bromalian 10 mg/kg/day
The number of patients suffering from well-documented malignancies to be assigned to this group will be at least 30: with mixed types of carcinoma of breast, lung, colon, gastro-intestinal, ovarian, cervical, uterine, prostatic, bladder, hepatic, lymphoma, melanoma and so forth. These patients will be given Bromelain at 500 mg/day, divided into two doses of 250 mg/dose and taken with meals.

- Using NCI standard measurement to measure primary target lesion size of various types of cancer pstients [ Time Frame: 24 weeks ]Measurement of the size of tumor lesion in centimeters and shrinking of regional lymphnodes
- Using NCI standard measurement to measure non-target lesion (tumor markers) value in various types of cancer patients [ Time Frame: 24 weeks ]Measurement of the non-target lesions (tumor markers) values decrease or increase by laboratory tests
- Using NCI standard to measure serious and non-serious outcomes in toxicity in various types of cancer patients [ Time Frame: 24 weeks ]Using standard serious and non-serious toxicity measurement in hematology, hepato-reno systems in cancer patients

Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
-
Patients suffering from late stage breast, lung, colon, cervical, ovarian, and uterine cancers in stages III and IV, with tissue proof of well-documented malignancies, whether by tissue biopsies and/or laparatomy or thoracotomy and have not been helped by conventional radiation therapy and/or chemotherapies are eligible for this study. Additionally the following conditions must be met:
- Patient's age is between 18 and 85 years.
- Patient is not taking anticoagulants or on antiplatelet therapy.
- Patient does not have a history of abdominal fistula, gastroenteral perforation, peptic ulcer diseases, or intra-abdominal abscess within 6 months prior to study enrollment.
- Patient has not had major surgery within 4 weeks prior to study enrollment. Patients who have not recovered from adverse events due to surgery performed more than 4 weeks earlier are not eligible for this study.
- Patient does not currently have uncontrolled hypertension, diabetes, or clinically significant cardiac arrhythmia.

- Patient does not have significant abnormal hepatic and/or renal function.
- Patient's tumors are measurable; between 0.2 - 10 cm in size and number between 1 - 15. All measurable tumors that have spread to the bones, liver, lung, kidney, and abdomen will be included in the data analysis.
Exclusion Criteria:
-
Patients with following conditions will be excluded from the study:
- Hemoglobulin less than 9 g/dL and WBC less than 4.0 k/µL.
- Platelet count less than 100,000/µL.
- INR greater than 1.5
- Patient currently taking therapeutic doses of warfarin or anti anti-platelet agents.
- Patient has a history of abdominal fistula, gastrointestinal perforation, peptic ulcer disease, or intra-abdominal abscess within 6 months prior to study enrollment.
- Patient currently has uncontrolled hypertension, diabetes, or clinically significant cardiac arrhythmia.
- Patient who had major surgery performed within 4 weeks prior to entering the study; and patients who have not recovered from adverse events due to surgery performed more than 4 weeks earlier.
- Patient with a history of allergic reaction to Bromelain or pineapple-containing products.
- Female patients who are pregnant or breastfeeding.
- Patient with tumors that are widely spread in the chest and abdomen that cannot be measured by CT scan.
Patients who are eligible for this study will be randomly assigned to either the low dose group or the high dose group by a coin toss. Each study subject will be assigned a patient number for the purpose of this study.
