In the department of coloproctology of NORC MH RUz 17 patients with disseminated forms of colorectal cancer was made the study of oncogenes and complex treatment by 2 protocols using FOLFOX4 regime and FOLFIRI regime. In second protocol there used 2 sessions of endolymphatical polychemotherapy FOLFOX4 regime against EHFhyperthermia. All patients were performed additional investigations directed to study the presence of multiple drug resistance in them where definition of р53, bcl2 oncogene expression. In our observations we followed resistance to FOLFOX4 scheme in 4 patients, and to FOLFIRI scheme in 2 cases. In our studies hyperexpression of oncoproteine р53 was correlated with the effect of conducted therapy whereas hyperexpr, Navruzov S. N., Abdujapparov S. B., Pulatov D. A., Islamov H.

Aim of investigation: to study immediate and remote results of standard and extended lymphodissection in patients with rectal cancer. Material and methods: 132 patients with rectal cancer were performed radical surgery with lymphodissection in D2 and D3 volume according to a height of tumor location. In immediate postoperated period there were noted complications in 4 patients that made up 3,03%. Observation time was 5 years. Tumor recurrence was reported in 5 patients (3,8%). In remote period metastases were revealed in 8 patients (6,6%). 5year total survival rate was 78,5±4,2% at stage II. 5year total survival rate was 56,4±3,7% at stage III. Comparing the results of standard and extended lymphodissection it was noted statistically authentic increase of 5 year survival rate in patients at stage III. Obtained data allow to come to the conclusion about reasonability of performance of different variants of lymphodissection for patients with rectal cancer at stages II and III., Navruzov S.
