Summary

The data will be obtained from 10 tertiary centers located in Poland (Cracow - coordinating center, Warsaw - 3 centers, Sosnowiec, Szczecin, Bydgoszcz, Lublin, Gdansk, Poznan) and 5 foreign centers.

The analyses will include patients with rectal cancer operated on between 2013-2019. A database in MS Excel is prepared that consists of following data:

* Type of neoadjuvant treatment (if any)
* Time-interval between the end of neoadjuvant treatment and surgery
* Type of surgery
* Staging of rectal cancer i.e. (y)pTNM
* Number of retrieved lymph nodes
* Number of lymph nodes with metastases
* R classification (R0, R1, R2)
* Preoperative medications (metformin, statins, NSAIDs, anticoagulants)
* Recurrence date and type (local, systemic, both diagnosed at the same time)
* Date of death or date of last follow-up visit

The aims of the study are following:

1. Establishing whether neoadjuvant treatment (PSCR or chemoradiotherapy) influences number of retrieved lymph nodes in rectal cancer
2. Establishing whether time-interval between the end of PSCR and surgery influences lymph node yield
3. Establishing the prognostic value of lymph node ratio - validation of the previously calculated cutoff point at the level of 0.41
4. Determining independent prognostic factors in rectal cancer - in particular related to medications taken before the operation, metformin and anti diabetic drugs in the first place

Conditions
