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

objectiveThe role of adjuvant chemotherapy as an addition or alternative to radiotherapy for early-stage high-risk endometrioid endometrial cancer is controversial. This study aimed to investigate the role of adjuvant chemotherapy in early-stage high-risk endometrioid endometrial cancer.

methodsWe identified patients with stage I or II endometrioid grade 2 or 3 endometrial cancer with myometrial invasion >50% and negative lymph nodes after pelvic with or without para-aortic lymphadenectomy at four institutions (USA and Italy). Associations between chemotherapy and cause-specific and recurrence-free survival were assessed with Cox proportional hazards models. Hematogenous, peritoneal, and lymphatic recurrences were defined as 'non-vaginal'.

resultsWe identified 329 patients of mean (SD) age 66.4 (9.8) years. The median follow-up among those alive was 84 (IQR 44-133) months. The 5-year cause-specific survival was 86.1% (95% CI 82.0% to 90.4%) and the 5-year recurrence-free survival was 82.2% (95% CI 77.9% to 86.8%). Stage II (vs stage IB) was associated with poorer cause-specific and recurrence-free survival. A total of 58 (90.6%) of 64 patients who had chemotherapy had 4-6 cycles of platinum-based regimen. In adjusted analysis, we did not observe a statistically significant improvement in cause-specific survival (HR 0.34; 95% CI 0.11 to 1.03; p=0.06) or non-vaginal recurrence-free survival (HR 0.36; 95% CI 0.12 to 1.08; p=0.07) with adjuvant chemotherapy. Sixteen of 18 lymphatic recurrences (88.9%; 3/5 pelvic, all 13 para-aortic) were observed in the 265 patients who did not receive adjuvant chemotherapy. Among stage II patients, no deaths (100% 5-year recurrence-free survival) were observed in the eight patients who received adjuvant chemotherapy compared with 66% 5-year recurrence-free survival in the 34 patients who did not.

conclusionAlthough we observed that adjuvant chemotherapy was associated with improved oncologic outcomes in early-stage high-risk endometrioid endometrial cancer, the associations did not meet conventional levels of statistical significance. Further research is warranted in this relatively uncommon subgroup of patients.
