简要总结
The best way to treat MBO in patients with ovarian cancer has not been studied enough by trials that assess how more than one treatment arm (surgical, chemotherapeutic, supportive care approaches) affects clinical outcomes like resolution of bowel obstruction, survival, and quality of life. To improve patient outcomes, we must assess which patients will do better with palliative surgery, chemotherapy, or best supportive care. This study will gather safety information, and how reasonable it is to give chemotherapy and BSC to patients with advanced ovarian cancer and MBO who are non-surgical candidates. This study will also look into the effects of chemotherapy and BSC on the quality of life and resolution of bowel obstruction, in hopes to perform future studies that lead to the best management of MBO.
详细描述
The optimal management of MBO in patients with ovarian cancer has not been defined by proper prospective randomized control trials evaluating the impact of defined multidisciplinary treatment arms (surgical, chemotherapeutic, supportive care approaches) on important clinical outcomes including resolution of bowel obstruction, survival endpoints and validated quality of life outcomes. In order to improve patient outcomes, we must define which patients will benefit from palliative surgery, which patients are appropriate candidates for chemotherapy and which patients will benefit most from best supportive care. This study will determine the safety, feasibility of chemotherapy and BSC in patients with advanced ovarian cancer presenting with MBO who are initially deemed non-surgical candidates and will identify the impact of chemotherapy and BSC on quality of life and resolution of bowel obstruction, in preparation for future prospective randomized studies to determine the optimal management of MBO.

入选标准
- •Hospital admission and diagnosis compatible with Malignant Bowel Obstruction, as defined below:
- •A diagnosis of primary ovarian cancer, primary peritoneal cancer or fallopian tube cancer

结局指标
主要结局
Overall Safety Profile
时间窗: Day 1 of treatment until resolution of symptoms
Type, frequency, severity (NCI CTCAE v.3.0.1) and relationship to trial treatment of adverse events and laboratory abnormalities. Frequency and severity of adverse events will be tabulated using counts and proportions detailing frequently occurring, serious and severe events of interest.
Quality of Life Scores at Baseline, Day 30 and Day 90
时间窗: Day 1 of treatment until resolution of symptoms
Quality of life scores will be tabulated using counts and summary statistics. We hypothesize that at 30 days from treatment, there may be no improvement in quality of life scores compared to baseline. We hypothesize that at 90 days from treatment, there will be an improvement in quality of life scores from baseline by one third standard deviation. Paired T test and Mixed model will be used to make the comparison over different time period.
Time to Resolution of Bowel Obstruction
时间窗: Day 1 of treatment until resolution of symptoms
Time to resolution of bowel obstruction and time to recurrence of bowel obstruction will be assessed using summary statistics including mean, median, counts and proportion, to summarize the patients.
次要结局
- Survival(30 days, 60 days, and 90 days from treatment start date)
- Evaluation of Toxicity(Time of consent until resolution of symptoms)
