About
The purpose of this study is to see whether one dose of palliative radiation therapy directed to the liver in combination with standard BSC might help to reduce liver pain/discomfort due to cancer when compared to getting standard BSC alone.
Full description
The standard treatment for liver cancer pain or discomfort like yours is known as best supportive care (BSC) and includes pain-relieving medicines called analgesics. This type of treatment can help in some cases; however, some analgesics require a healthy liver to work properly. This means that there are many patients who have a hard time managing their liver cancer pain/discomfort with BSC alone.
Sometimes radiation therapy is given in the "palliative" setting meaning it is designed to treat the pain/discomfort and not necessarily to shrink or eliminate the tumour. Palliative radiation therapy is often given when patients have painful bone tumours, but is not yet widely used to treat liver pain/discomfort. Palliative radiation therapy is usually given in smaller amounts and less frequently than other kinds of radiation therapy.

Inclusion criteria
A diagnosis of cancer by at least one criterion listed below:
Largest burden of cancer in the liver is confirmed with CT scan or MRI corresponding to the clinically painful area done within 120 days prior to randomization.
Diffuse (infiltrative involving > 50% of the liver), multifocal (> 10 lesions) or locally advanced cancer (at least one lesion > 10cm, vascular invasion, or multiple lesions with at least one > 6cm) involving the liver.
In the investigator's opinion, patient is unsuitable for or refractory to standard local and regional therapies. For example:
Unsuitable for, high risk for, or refractory to, standard systemic chemotherapy or targeted therapy (e.g. sorafenib).
Patient reports moderate or severe pain/discomfort prior to the baseline evaluation and this pain is considered "stable" over a period of up to 7 days prior to randomization.
Definition of moderate pain:
Patient reports level of 4-6 (on a BPI scale from 0 to 10) pain or discomfort "at its worst in the past 24 hours", occurring in the right upper quadrant of the abdomen, the upper abdomen and/or referred to the right shoulder, attributable to liver cancer.
Definition of severe pain:
Patient reports level of 7-10 (on a BPI scale from 0 to 10) pain or discomfort "at its worst in the past 24 hours", occurring in the right upper quadrant of the abdomen, the upper abdomen and/or referred to the right shoulder, attributable to liver cancer.
Definition of "stable" pain:
Patient must show moderate or severe "stable" pain by reporting a score of 4 or greater (on 2 separate days within the 7 day period prior to randomization) with the difference of these scores being 0, 1, 2 or 3.
Patient reports moderate or severe pain (i.e. pain score is 4 or higher). This baseline score must also be stable compared to the most recent pre-baseline pain score with the difference between these scores being 0, 1, 2, or 3.
Blood work obtained within 14 days prior to randomization as follows:
Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-3 within 14 days of Randomization (see Appendix II).
Life expectancy of > 3 months.
18 years of age or older at the time of randomization.
Patient is willing to complete the Pre-Baseline Pain/Discomfort Questionnaire and the Pain/Discomfort and Medication Questionnaire in English, French or other validated language (please contact the HE.1 Study Coordinator). The baseline assessment must be completed within required timelines prior to randomization. Unwillingness to complete the Pre-Baseline Pain/Discomfort Questionnaire and Pain/Discomfort and Medication Questionnaire will make the patient ineligible for the study.
Patient is able (i.e. sufficiently fluent) and willing to complete the QoL questionnaires in English, French or other languages in which the FACT-Hep is available. The baseline assessment must be completed within required timelines prior to randomization.
Inability (illiteracy in languages listed above, loss of sight, or other equivalent reason) to complete the questionnaires will not make the patient ineligible for the study. However, ability but unwillingness to complete the QoL questionnaires will make the patient ineligible for QoL assessment.
Women/men of childbearing potential must have agreed to use a highly effective contraceptive method. A woman is considered to be of "childbearing potential" if she has had menses at any time in the preceding 12 consecutive months. In addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation, or vasectomy/vasectomized partner. However, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures.
Women of childbearing potential will have a pregnancy test to determine eligibility as part of the Pre-Study Evaluation; this may include an ultrasound to rule-out pregnancy if a false-positive is suspected. For example, when beta-human chorionic gonadotropin is high and partner is vasectomized, it may be associated with tumour production of hCG, as seen with some cancers. Patient will be considered eligible if an ultrasound is negative for pregnancy
