Outcome of rectal cancer after radiotherapy with a long or short waiting period before surgery, a descriptive clinical study.
Article in Journal of gastrointestinal oncology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundRadiotherapy and surgery have shown to improve local control and survival in rectal cancer. There are two applied schedules; radiotherapy with a long or short waiting period before surgery. The effect on survival and recurrence of both schedules was studied.
methodsAll consecutive patients with rectal cancer in the period 2002-2008 were included. Data were gathered on survival, tumour stage, co-morbidity score, and cause of death. The patients were divided in three groups: group 1 patients undergoing surgery without neo-adjuvant radiotherapy; group 2 patients undergoing radiotherapy followed by immediate surgery; and group 3 patients treated with (chemo) radiotherapy followed by a longer waiting period.
resultsA total of 113 patients with rectal cancer underwent surgery. Twenty two patients in group 1, 71 patients in group 2, and 20 in group 3. There was no difference in gender, time to recurrence, co-morbidity score, or causes of death. Fifty percent of patients died due to non-cancer related causes. Mean age in patients of group 3 was significantly lower than in groups 1 and 2 (P=0.02). There was a trend towards a lower tumour stage in the patients of group 3. Overall five year survival was 32% in group 1, 48% in group 2, and 35% in group 3.
conclusionsNeo-adjuvant radiotherapy seems to be of benefit in daily practice in patients with rectal cancer. A longer waiting period results in down-staging. Clinicians have to be aware that many patients will die due to other causes than those related to the rectal cancer.
