简要总结
This randomized phase II trial studies how well cisplatin and fluorouracil work compared with carboplatin and paclitaxel in treating patients with anal cancer that cannot be removed by surgery, has come back at or near the same place as the primary tumor, or spread to other places in the body. Drugs used in chemotherapy, such as cisplatin, fluorouracil, carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether cisplatin and fluorouracil are more effective than carboplatin and paclitaxel in treating anal cancer.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate best overall response rate (ORR).
SECONDARY OBJECTIVES:
I. Overall survival (OS). II. Progression free survival (PFS). III. Disease control rate (DCR) (stable disease [SD] or better) at 12 and 24 weeks.
IV. Best ORR of non-irradiated lesions. V. Anti-tumor activity and magnitude of response as captured by waterfall plot analyses.

- •Known history of active hepatitis B or hepatitis C infection
- •Serious active infection requiring intravenous (i.v.) antibiotics at enrollment
- •Other malignancy within the last 5 years, except for adequately treated carcinoma in situ of the cervix or squamous carcinoma of the skin, or adequately controlled limited basal cell skin cancer
- •Other clinically significant disease or co-morbidity that may adversely affect the safe delivery of treatment within this trial
- •Known hypersensitivity to any of the study drugs or excipients
- •Known peripheral neuropathy > grade 1 (absence of deep tendon reflexes as the sole neurological abnormality does not render the patient ineligible)
- •Pre-existing hearing impairment
- •Patients planning for a live vaccine
- •Pregnant or lactating females
