Treatment of advanced soft tissue sarcoma (STS) has passed a difficult and long way of evolution from amputation surgery to complex limb-salvage interventions, but the problem of local recurrence is relevant today as 100 years ago. Tactics of monitoring after treatment of STS depends on the individual risk of recurrence and should be based on simple and effective diagnostic methods. Developing of new individualized approaches to patient follow up after primary treatment of STS is extremely necessary for early detection of local recurrence and improvement of overall survival, which requires close cooperation of clinical, morphological and radiology specialists.

Currently, the methods of delivering high local doses of chemotherapy to locally-advanced tumors of the extremities, while avoiding systemic toxicity, are actively investigated. Isolated regional limb chemoperfusion is one of these methods. From 2004 to 2014, a total of 70 patients underwent isolated limb perfusion (ILP) for locally-advanced soft tissue sarcoma and transit metastases of extremity melanoma. Complications of ILP, causes of their occurrence and preventive measures were analyzed.

Results of molecular genetic study of BRCA1gene expression in patients with endocrine tumors of the gastrointestinal tract were presented. Based on the analysis of survival rates in patients with endocrine tumors of the gastrointestinal tract, the BRCA1expression level was suggested can be used as a prognostic criterion and as a factor determining the advisability of administration of platinum-based drugs. It was found that the more aggressive neuroendocrine tumors had the lower BRCA1expression. Therefore, administration of platinumcontaining chemotherapy is unlikely to offer any benefit for these patients.

It was found that up to now a significant number of patients with primary skin melanoma continued to have non-radical surgery. Based on the analysis of clinical and morphological data on 288 of these patients it was revealed that most non-radical treatment was performed for patients who had had primary skin melanoma of linear dimensions of 1 cm and a pink color. It was proved that patients with tumors of the skin should first be examined by the oncologist. A lack of knowledge of semiotics of primary skin melanoma was revealed among doctors. Widely used diagnostic biopsy of the primary tumor with subsequent cytology is recommended.

In experimental and clinical research carried out studying of influence of neoadjyuvant photodynamic therapy on T- and B-cellular immune answer in surgical treatment of patients of a melanoma of skin of the I–III stage. PDT was executed to 25 patients two days prior to surgical removal of primary tumor from July, 2012 to January, 2013. As a result of the conducted research it was revealed that: the increase in concentration fotoditaziny doesn‘t lead to increase in quantity of tumoral cages at stages early apoptosis; lengthening of time of an exposition leads to increase in a share of late forms apoptosis, and FDT use with fotoditaziny in a dose of 50,0 mg with the subsequent radiation (662 nanometers, 400 J) in 2 days prior to surgical intervention promotes T- and B-cellular link of immune system.

Risk factors for different types of recurrences in 291 patients with primary skin melanoma after radical surgery have been studied. The main risk factors for recurrence have been found to be: the patients age, location of primary melanoma, depth of melanoma according to Breslows classification and the level of invasion according to Clark.

The review presents the current treatment methods for primary skin melanoma. Special attention has been paid to the technique of adequate surgical treatment for primary tumor and necessity of preventive regional lymphadenectomy. The problems of isolated regional perfusion, photodynamic therapy and sentinel lymph node biopsy have been discussed. Indications to adjuvant treatment for patients with primary skin melanoma have been reported.

Based on the treatment outcomes of 1308 patients with primary skin melanoma, recommendations for performing adequate surgery with respect to the extent of tumor involvement have been given. To determine the extent of skin melanoma involvement, ultrasonic dopplerography with color mapping of regional lymph nodes seems to be advisable.
