Abstract:

Introduction: currently, chemoradiation therapy is widely used as the main method of specific treatment for locally advanced head and neck cancer. Previously it was believed that radiation damage of carotid arteries occurs only several years after treatment.

Material and methods: article presents two case reports of internal carotid artery stenosis which arose directly during the course of chemoradiation of head and neck malignant tumors. In the first case, patient K., 54 years old, had laryngeal cancer (stage III: T3N1M0), in the second case, patient M., 40 years old, had tongue cancer (stage I: T1N0M0).

Conlusion: article presents angiographically confirmed carotid artery stenosis arisen directly during chemoradiation and in early stages after its completion. The discussion presents data on the incidence of stenosing lesions of carotid arteries, cerebrovascular events among patients undergoing radiation therapy. It is necessary to draw attention of specialists to the problem of early stenosis of carotid arteries during radiation and chemoradiation therapy of head and neck tumors.

 

 

Abstract:

Cervical cancer (CC) is one of the most common oncological disease in the world. There are lots of methods to treat it. Often we use radiation therapy (RT), chemotherapy (CT), surgical treatment. However, when on one hand we have successes, on the other hand we have a number of unsolved problems. To solve them, we study the method of chemoembolization of uterine arteries (CUA). This treatment option is being studied as one of promising methods in the complex or combined radiation treatment of primary and recurrent cervical cancer. This allows, with minimal trauma and relapse rate, to stop bleeding and reduce the size of the tumor. In this article a number of literature sources about using embolization or chemoembolization and results of treatment with CUA has been analyzed.

Abstract:

Purpose. Was to determine the possibilities of transrectal ultrasound research (TUR) in grayscale-mode with the use of ultrasound angiography in diagnostics of rectitis and in monitoring its treatment in patients with prostate cancet (PC) after radiation therapy.

Materials and methods. The research consists of 62 patients with verified localized prostatic cancer (T13N01M0), which have already obtained conformed radiation therapy (RT) as a radical strategy. To estimate expressive radiation reaction patients were underwent transrectal ultrasound research before, during and after (in 3, 6, 12 months) radiation therapy. During the experiment, using grayscale-mode, the thickness of rectum front wall, its structure and echogenicity, and prostata capsula propria (lat.) tracking were estimated in dynamics. Vascularization of rectum front wall and pararectal cellulose was also analyzed in dynamics. Results of transrectal ultrasound were compared with clinical symptoms during the whole period of supervision, and were registered on the basis of patient’s personal note during and after treatment.

Results. Based on patients complaints we have noticed development of radiation rectitis (radiation therapy after-effect) which can be registered as higher thickness of rectum front wall, changes in its structure, decreasement of echogenicity and increased vascularization. The major part of patients with these changes noticed that such symptoms were therapeutically eliminated during supervision. Such echo-graphic changes won’t appear in case of prostate cancer progression and it can be used as a differential diagnostics between radiation therapy after-effect and prostate cancer growth.

Conclusion. Transrectal ultrasound allows to visualize early radiation rectitis implications in patients with prostatic cancer during radiation theraphy, and can promote the necessary treatment correction and advanced symptomatic therapy.

Abstract:

Since December 2010 till September 2012, 24 patients with III stage laryngeal carcinoma (T3_4NxxM0) underwent chemoradiation therapy Intra-arterial chemotherapy via both superior thyroid and laryngeal arteries with intermitting in 30-45 minutes infusions of cisplatin and 5-fluorouracil was done. Average doses of cisplatin consist 75mg/m2, and 5-fluorouracil dose was1000mg/m2. In 48 hours multifractional radiotherapy started (1,1Gy x 2 per day, 5 days per week) with planned total dose 74-78Gy Then total dose was 26-30Gy and 50Gy pauses for 2 or 3 days in radiotherapy established for repeated same intra-arterial chemotherapy In 21 patients (87,5%) total regress of the tumor was marked. In 3 patients (12,5%) sclerosis of residual volume developed without tumor cells in control biopsies. In the only patient (4,2%) after 6 months reoccurrence was marked and dissection laryngectomy managed. Stability of positive results we observe during 12 months following such chemoradiation therapy.

Abstract:

Aim: was to proceed comparative analysis of immediate and long-term results of chemoradiation treatment of unresectable local-spread oropharyngeal cancer with use of standart chemoradiatior therapy with intravenous chemoinjection and individual volume-controlled superselective intraarterial chemotherapy.

Materials and methods: 43 patients with unresectable oropharyngeal cancer were included in trial comparing intra-arterial (IA) and intravenous (IV) chemoradiation. IV chemoradiation (n=19 patients) comprised 3-4 times of 100 mg/m2 cisplatin infusion on days 1, 22, 43 combined 2Gy x 5 days fractions with total radiation dose 72Gy The IA chemoradiation group (n=24) comprised 3 or 4 x 90 mg/m2 cisplatin administered in the tumor-feeding artery by personified volume- controlled targeted perfusion. The induction IA chemotherapy was given one day before radiation. Then IA chemotherapy conducted regularly 22, 43, 64 days followed radiation.

Results: we made 86 IA procedures and had no IA-related death or procedure related complications. Five patients of IA group were excluded from long term analysis because of non-comleted protocol. The median follow-up was 21±2.3 months in IA group and 36 months in all patients in IV therapy group. In 19 patients received IA chemoradiotherapy protocol - 100% complete response (CR) and in IV chemoradiotherapy - only in 10 (53%) of 19 patients (ф = 6,820, р<0.05). CR was noted in 8 patients with N1 lymph-nodes and in 9 of 10 patients with N2 lymph nodes in IA therapy group. Initial lymph nodes regress more than 80-90% was observed and follow up improvement was confirmed by PET-CT. One-year overall survival (OS) rates were 95% and 79%, respectively in IA and IV groups (not significant OR = 4,8; ф = 1,51; р = 0,05), but two year OS rates were 90% and 58%, respectively (р<0,05). These data are encourage but further follow-up results need to be investigated.
