Association between histological type of tumour growth and patient survival in t2-t3 lymph node-negative rectal cancer treated with sphincter-preserving total mesorectal excision.

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
For rectal cancer patients without nodal metastases the identification of unfavourable factors can be helpful for the better selection for adjuvant therapy and multimodality treatment. The aim of this study was to evaluate the impact of clinico-histological parameters on prognosis in node-negative rectal cancer patients. One hundred and thirty-nine consecutive node negative rectal cancer patients with complete five-year follow-up were studied prospectively. All of them underwent curative anterior resection with total mesorectal excision technique. Seventy-eight patients with tumour penetration beyond the bowel wall received neo-adjuvant short-course radiation (25 Gy) followed by surgery within 1 week and postoperative chemotherapy with 5-fluorouracil and folinic acid in six cycles or adjuvant radiochemotherapy: irradiation (50.4 Gy) combined with chemotherapy (as above). Cancer-specific survival was calculated according to the Kaplan-Meier method. Variables significant in univariate analysis by log-rank test (P < 0.05) entered the Cox proportional hazard model. Survival was decreased for males, older patients (>60 years) with extraperitoneal, poorly differentiated cancers, tumours with mucinous histology and with the absence of lymphocytic infiltration but with the lack of statistical importance. Prognosis was significantly improved for patients with T2 tumours versus T3 (P < 0.01) and with cancers with expanding growth comparing to diffusely infiltrating ones (P < 0.01). In multivariate analysis these parameters significantly and independently influenced survival (P < 0.01 and P < 0.05, respectively). Diffusely infiltrating growth of tumour can reflect the more aggressive cancer behaviour and unfavourable course of disease despite the optimised local control. Apart from the extent of tumour penetration the type of invasive margin can be an additional parameter helpful for the optimal treatment planning and better patient selection for postoperative chemotherapy.
