Patient-reported outcomes during first-line palliative systemic therapy alternated with pressurized intraperitoneal aerosol chemotherapy for unresectable colorectal peritoneal metastases: a single-arm phase II trial (CRC-PIPAC-II).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe CRC-PIPAC-II study prospectively assessed bidirectional therapy (BT) consisting of first-line palliative systemic therapy and electrostatic precipitation oxaliplatin-based pressurized intraperitoneal aerosol chemotherapy (ePIPAC-OX) in patients with unresectable colorectal peritoneal metastases (CPM). This study describes the exploration of patient-reported outcomes (PROs).
methodsIn this phase II trial, 20 patients with isolated CPM were treated with up to three cycles of BT, each cycle consisting of two to three courses of systemic therapy, followed by ePIPAC-OX (92 mg/m
resultsTwenty patients underwent a total of 52 cycles of bidirectional therapy. Most PROs (29 of 37, 78%) were not significantly affected during trial treatment. In total, only eight PROs (22%) were significantly affected during trial treatment: Six PROs (index value, global health status, emotional functioning, C30, appetite, and insomnia) showed transient improvement at different time points. Two PROs transiently deteriorated: pain initially improved during the first BT cycle [- 16, p < 0.001] yet worsened temporarily one week after the first two BT cycles (+ 20, p < 0.001; + 17, p = 0.004; respectively). Abdominal pain worsened temporarily one week after the first BT cycle (+ 16, p = 0.004), before improving again four weeks after treatment ended (- 10, p = 0.004). All significant effects on Pros were clinically significant and all deteriorations in PROs were of temporary nature. DISCUSSION: Patients undergoing BT for unresectable CPM had significant, but reversible alterations in several PROs. Most affected PROs concerned improvements and only two PROs showed deteriorations. Both deteriorated PROs returned to baseline after trial treatment and were of a temporary nature. These outcomes help to design future studies on the role of ePIPAC in the palliative setting.
