1 · What the graph read from it

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.

2 · The registry

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

objectiveA Phase II study of CPT-11 in adults with recurrent, temozolomide (TMZ)-refractory, 1p19q co-deleted, anaplastic oligodendroglioma (AO) with a primary objective of determining 6-month progression free survival (PFS).

backgroundThere is no standard therapy for alkylator-resistant AO.

methodsTwenty-two patients (11 men; 11 women) ages 26-65 (median 40), with radiographically recurrent AO were enrolled. All patients had previously been treated with surgery, involved-field radiotherapy, and adjuvant chemotherapy (TMZ in 15; BCNU in 6). Fifteen patients were treated at first recurrence with an alternative chemotherapy. 13 patients underwent repeat surgery. All patients were treated at either first or second recurrence with CPT-11 administered intravenously once every 3 weeks. Neurological and neuroradiographic evaluations were performed every 8-9 weeks.

resultsAll patients were evaluable for toxicity and response. A total of 141 cycles of CPT-11 (median 3 cycles; range 3-18) were administered. CPT-11 related toxicity included diarrhea (14 patients; 4 grade 3), neutropenia (8; 4 grade 3), fatigue (12; 3 grade 3), and delayed nausea/vomiting (12; 3 grade 3). 5 patients (23%) demonstrated a partial radiographic response, 8 (36%) demonstrated stable disease and 9 (41%) had progressive disease following three cycles of CPT-11. Time to tumor progression ranged from 2 to 13.5 months (median: 4.5 months). Survival ranged from 3 to 21 months (median: 5.5 months). Six-month and 12-month PFS were 33% and 4.5% respectively.

conclusionsCPT-11 demonstrated modest efficacy (similar to other salvage glioma regimens) with acceptable toxicity in this cohort of adults with recurrent, 1p19q co-deleted AO all of whom had failed prior TMZ chemotherapy.
