Study Note
Brief summary
Three different groups of breast cancer patients were compared with each other after their operation: The first group received reflex therapy, the second head massage and the third nothing beyond usual care. Three different questionnaires were used in all groups to find out how they were doing in various psychological and physical areas before and after treatment. Very similar points were asked, namely general well-being, relaxation, happiness, energy and self-confidence. The people included in the groups were comparable in all respects at the beginning of the study. The group that received reflex therapy had demonstrably better values after the treatment than the group that did not receive any additional treatment in a total of 6 out of 34 comparisons and better values than the group that received the head massage in 1 out of 34 comparisons. These demonstrable differences are small (e.g. 119 instead of 112 total points for general well-being). The authors of the study emphasize these differences, but do not go into why no differences were found in other similar points.
Es wurden drei verschiedene Gruppen von Brustkrebspatientinnen nach ihrer Operation miteinander verglichen: Die erste Gruppe hat Reflextherapie bekommen, die zweite Kopfmassage und die dritte nichts weiter, was über die übliche Versorgung hinausging. In allen Gruppen wurden drei verschiedene Fragebögen angewendet, um herauszufinden wie es ihnen in verschiedenen psychischen und körperlichen Belangen jeweils vor und nach der Behandlung ging. Dabei wurden sehr ähnliche Punkte abgefragt, nämlich allgemeines Wohlbefinden, Entspannung, Fröhlichkeit, Energie, Selbstbewusstsein. Die Personen, die in den Gruppen eingeschlossen wurden, waren zu Beginn der Studie in allen Belangen vergleichbar. Die Gruppe, die Reflextherapie bekommen hat, hatte nach der Behandlung in insgesamt 6 von 34 erhobenen Vergleichen nachweislich bessere Werte als die Gruppe, die nichts zusätzliches bekommen hat und in 1 von 34 Vergleichen bessere Werte als die Gruppe, welche die Kopfmassage bekommen hat. Diese nachweislichen Unterschiede sind gering (z.B. 119 statt 112 Gesamtpunkte für allgemeines Wohlbefinden). Die Autoren der Studie heben diese Unterschiede sehr hervor, gehen aber nicht darauf ein, warum in anderen ähnlichen Punkten keine Unterschiede gefunden werden konnten.

In this case, participants dropped out of the study prematurely for reasons unrelated to the treatment.

Characteristics of participants
| Setting Refers to cancer therapy setting.</br>- Curative therapy: aims to completely eradicate a disease and achieve a full recovery; </br>- Neo-adjuvant therapy: form of curative therapy, given before the primary treatment for cancer (usually surgery); </br>- Adjuvant therapy: form of curative therapy, given after the primary treatment for cancer (usually surgery); </br>- Palliative therapy: focuses on providing relief from symptoms and improving the quality of life for patients, without necessarily targeting the underlying disease; </br>- Active surveillance: involves close monitoring of disease progression without any intervention (typically used for prostate cancer);</br>- No therapy setting: Patients who completed therapy/are currently not in cancer treatment, cancer survivors.
