[ALPPS in case of massive liver metastases].

It was presented the first experience of ALPPS technique using in treatment of massive liver metastases in the Urals. The technique allows to carry out surgical treatment without danger of development of post-operative liver failure. Also it permits to complete treatment during one hospitalization without stretching the therapeutic process in time.

[Immediate results of combined treatment for soft tissue sarcomas including intraoperative radiation therapy].

Nowadays the most popular and justified, from oncological positions, method of treatment for soft tissue sarcomas is a combined approach with the use of conservative surgery followed by postoperative radiation therapy. In this regard, intraoperative radiation therapy (IORT) in a single dose of 10-20 Gy is a method that optimizes the role of radiation therapy in treatment of this pathology allowing precise localization of radiation zone within the "tumor bed", thereby minimizing damage of normal tissues and critical organs. The aim of the study was to investigate the effect of IORT on the frequency and structure of post-operative complications. Testing group (n = 49) was compared to the group without IORT (n = 57) and group with only surgery (n = 171). According to the study it was not obtained statistically significant differences in the incidence of postoperative complications in the groups (p = 0,57), not marked influence on the structure of post-operative complications.

[Long-term results of combined treatment of soft tissue sarcoma with the use of intraoperative radiotherapy].

This retrospective study of long-term results of combined treatment of soft tissue sarcoma with the use of intraoperative radiotherapy (IORT) included 171 patients. Controls received adjuvant distant gamma-therapy (n = 57) or surgical treatment (n = 171). IORT significantly improved 5 year general (p = 0.025) and relapse-free (p < 0.025) survival rate and the same parameters in patients with a tumour larger than 5 cm (p = 0.0001). The intergroup difference regardless of tumour differentiation was insignificant (p =0.33), but survival rate tended to decrease in patients with moderately and weakly differentiated sarcomas (G2-3). It is concluded that combined treatment with IORT may be used as an alternative method for the treatment of moderately and weakly differentiated sarcomas.

[Extended preoperative course of radiotherapy as component of combined and complex treatment of locally-advanced ampular rectal cancer].

Sixty-two patients were treated for locally-advanced ampular rectal cancer at the Center's Clinic (2004-2008). Extended preoperative course of radiotherapy plus 5 = fluorouracil chemomodification was given to 55 patients (group 1) and the same plus hyperthermia--to 27 (group 2). Radiation injuries were reported in 37.1% (group 1) and 29.6% in group 2. Surgical complications occurred in 10 (group 1) (32.2%) and 8 (group 2) (32%). Relapse was registered in 3 (group 1) (12.5%) and 3 (group 2) (13.6%). Overall 3-year survival (group 1)--82%; (group 2)--63.9%; 3-year relapse-free survival (group 1)--69.8%; (group 2)--52.2%.

[Results of surgical treatment of locally-spread colorectal cancer].

During the period from 2001 to 2005 operations were performed on 186 patients with locally-spread colorectal cancer. In 132 cases (the 1st group) radical combined resections were performed, 54 patients (the 2nd group) underwent palliative operations. The morbidity rate was 18.2% (24 cases) in the first group and 7.4% (4 cases) in the second group. The mortality rate in the first group was 2.3% (3 cases), no mortality was observed in the second group. Overall 3-year survival in the first group was 69.9%, and no one patient of the second group survived longer than 3 years. Overall 5-year survival in the first group was 54.7%, and the relapse-free 5-year survival was 52.8%. The data obtained have shown the effectiveness of combined resections in treatment of locally-spread colorectal cancer. We suggest that further improvement of long-term results can be achieved using chemoradiation.

[Expanded D2 lymphodissection in combined treatment of gastric cancer: unification of treatment approaches].

The authors present an analysis of results of using D2 operations in combined treatment of gastric cancer. Such volumes of operations combined with preoperative irradiation are not followed by greater number of complications and lethality. The incidence of progressing in terms more than a year proved to be considerably lower in the group of patients with combined treatment with D2 lymphodissection than in the groups without lymphodissection and preoperative radiation therapy.

[Value of magnetic resonance imaging in the diagnosis of recurrent colorectal cancer].

To diagnose recurrent colorectal cancer is an urgent problem of oncoproctology. Eighty patients with suspected recurrent colon tumor were examined. All the patients underwent irrigoscopy, colonoscopy, magnetic resonance imaging of the abdomen and small pelvis. The major magnetic resonance symptoms of recurrent colon tumors were studied; a differential diagnosis of recurrent processes and postoperative changes at the site of intervention was made.
