Brief summary
The incidence and severity of chemotherapy-induced nausea and vomiting (CINV) in patients receiving R-CHOP chemotherapy for in non-Hodgkin's lymphoma is not well documented. The contribution of prednisolone to CINV control in the R-CHOP regimen is also unclear. This study aims to evaluate the overall effectiveness of antiemetic control using a standardised 5HT3 (5-Hydroxytryptamine 3) antagonist-containing regimen (e.g. ondansetron) in a heterogeneous group of patients receiving R-CHOP chemotherapy (Rituximab Doxorubicin Vincristine Cyclophosphamide Prednisolone).
Detailed description
The aim of this study will be to investigate the incidence and severity of CINV in patients receiving R-CHOP for the treatment of non-Hodgkin lymphoma and standardised antiemetic prophylaxis. The study hypothesises that the control of delayed nausea and emesis is suboptimal in a proportion of patients receiving R-CHOP regimens and that delayed CINV is not prevented by use of 5HT3 antagonists beyond the first day of use post-chemotherapy administration. Participating institutions will prospectively collect data on the incidence of CINV, the severity of CINV, the use of break through/rescue medication for episodes of CINV uncontrolled by prescribed regular antiemetics, the effectiveness of additional measures used when previous CINV control has been inadequate (for example the use of aprepitant as an additional measure in subsequent cycles) and the major side-effects likely to be related to the antiemetics. The analysis of these results will determine the incidence and severity of CINV in patients receiving R-CHOP and the effectiveness of the prescribed antiemetic regimens. Analysis will also determine if the control and incidence of CINV is a significant problem in defined subgroups of patients receiving R-CHOP and could inform the design of future research (or an extension of the current protocol) in this area. Sub groups for investigation will include patients with advanced disease, those with abdominal involvement, those receiving R-CHOP every 14 days versus every 21 days (R-CHOP14 versus R-CHOP21), those receiving 6 or 8 treatment cycles of R-CHOP, older patients, younger females etc. A potential randomised study evaluating the role of aprepitant could be contemplated in high risk groups.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Complete Response, Acute Phase (Day 1), Cycle 1 | Day 1 | The proportion of patients experiencing a complete response defined as no vomiting and no use of breakthrough medication in the acute phase (day 1: 0 - 24 hours) of the first cycle of R-CHOP chemotherapy |
| Complete Response, Delayed Phase (Days 2 to 11), Cycle 1 | Days 2 to 11 | The proportion of patients experiencing a complete response defined as no vomiting and no use of breakthrough medication in the delayed phase (days 2 - 11 inclusive) of the first cycle of R-CHOP chemotherapy |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Failure of standard anti-emetic prophylaxis, Day 1 to Day 11, Cycle 1 and beyond | Day 1 to Day 11 | Failure of standard anti-emetic prophylaxis in the acute and delayed phase of any one cycle of chemotherapy requiring aprepitant as secondary prophylaxis in subsequent cycles. Failure will be defined as the occurrence of any of the following either during or beyond cycle day 1: * One or more episodes of vomiting * One or more episodes of nausea requiring the use of 1 or more doses of breakthrough anti-emetics * An episode of nausea requiring the use of breakthrough anti-emetics across multiple days * An episode of nausea measuring \> 2.5cm on a 0 - 10cm visual analogue scale * Nausea and/or vomiting that in the clinicians opinion requires use of aprepitant in future cycles |
| Complete Response - Cycle 2 and beyond | Day 1 to Day 11 | Complete response in the acute and delayed phases of each of cycles 2 and beyond of R-CHOP chemotherapy |
| Severity of common adverse events associated with anti-emetics | Day 1 to Day 11 | Adverse Events (all grades) of the anti-emetic regimen in each cycle of R-CHOP chemotherapy |
| Frequency of common adverse events associated with anti-emetics | Day 1 to Day 11 | Adverse Events (all grades) of the anti-emetic regimen in each cycle of R-CHOP chemotherapy |
| No Significant Nausea - Cycle 2 and beyond | Day 1 to Day 11 | No significant nausea (defined as a nausea experience score of \<2.5cm on a 0 - 10cm visual analogue scale) in the acute and delayed phases of each of cycles 2 and beyond of R-CHOP chemotherapy |
