Abundance of Tumor-Infiltrating B Cells in Human Epithelial Malignancies.

Cancer is a major global health problem. The type of malignant neoplasm and the potency of the immune response against tumors are two of the key factors influencing the outcome of the disease. The degree of tumor infiltration by lymphocytes plays an important role in antitumor response development, generally correlating with a favorable prognosis of treatment for certain cancers.

Thoracoscopic pneumonectomy in patient with unilateral absence of the left pulmonary artery accompanied by the left lung cancer.

Unilateral absence of the pulmonary artery is a rare congenital cardiovascular anomaly. Unilateral absence of the pulmonary artery is often accompanied by cardiovascular disorders but also can occur in an isolated manner. We present a case of female patient, in which the absence of the left pulmonary artery was revealed and the left lower lobe adenocarcinoma was diagnosed.

[Solitary fibrous tumor of pleura (symptoms, diagnosis, treatment)].

Objective: Optimization of diagnosis and treatment of patients with solitary fibrous tumor of pleura, analysis of overall survival and disease-free survival, predictors of recurrence.

Material And Methods: There were 66 patients with solitary fibrous tumor of pleura (26 men and 40 women) aged 57.6 years (range 26-80 years).

Uniportal video-assisted thoracoscopic carinal resections: technical aspects and outcomes.

Objectives: Important benefits in uniportal video-assisted thoracoscopic surgery (VATS) for lung cancer have recently been achieved. However, the use of this technique for complex sleeve procedures is limited. We describe the technical aspects of and patient outcomes following carinal resections using uniportal VATS.

[Gastrointestinal stromal tumors: surgical treatment and targeted therapy].

Aim: To improve surgical and complex treatment of patients with gastrointestinal stromal tumors (GIST).

Material And Methods: Our analysis included 97 GIST patients who were at Petrovsky Russian Research Center of Surgery and Moscow City Oncological Hospital #62 from January 2006 to September 2016.

Results: Advisability of surgery for GIST patients was confirmed.

Preoperative chemotherapy in patients with resectable esophageal carcinoma: a single center Phase II study.

Objective: The role of preoperative chemotherapy in squamous cell esophageal carcinoma remains controversial. A prospective trial was initiated to investigate whether preoperative chemotherapy followed by surgery results in increased progression-free survival in patients with resectable thoracic esophageal carcinoma.

Methods: Patients with Stage IIb-IIIa/b resectable esophageal carcinoma were eligible for the study.

[Thoracolaparoscopic simultaneous operations on esophagus].

Extirpation or subtotal resection of esophagus was performed in 14 patients by using of thoracolaparoscopic technique in terms from November 2011 to March 2014. The mean patients' age was 56 years old (27-67 years). In 10 patients indications for surgery included benign esophagus diseases such as cardiospasm stage IV (2 cases), peptic stricture (5 cases) and burn stricture (3 cases).

[Case of successful prevention of multiple organ dysfunctions in 74 years old patient with sepsis after Crawford surgery complicated with pleural empyema, chest wall tissues infection and osteomyelitis of ribs].

The article deals with a clinical case demonstrating that patient's elderly age is not an absolute contraindication for complex surgery in spite of high risk of postoperative complications. Early diagnostics, target treatment of the infection cite with vacuum-assisted therapy for wounds and the treatment of infectious complications based on individual characteristics of elderly patient with sepsis as an outcome of prosthetic thoracoabdominal aortic repair allowed avoiding multiple organ dysfunctions in the patient.

[Immunohistochemical study of epidermal growth factor receptor expression in esophageal squamous cell carcinoma].

Primary tumors from 31 patients with esophageal squamous cell carcinoma (ESCC) were immunohistochemically studied for the expression of markers of ESCC in order to define the clinical value of the levels of EGFR and HER-2 in the tumors. EGFR and HER-2 hyperexpression in the tumors of patients with ESCC was ascertained to be an important marker for the analysis of the clinical features of ESCC. There was an association of the elevated levels of EGFR and HER-2 in the tumors of ESCC patients with the presence of vascular tumor invasion (p = 0.

Squamous cell carcinoma of the esophagus: evaluation of the status of epidermal growth factor receptors (EGFR and HER-2) by immunohistochemistry and in situ hybridization.

We performed a parallel evaluation of the status of epidermal growth factor receptors EGFR and HER-2 in tumor samples from 31 patients with squamous cell carcinoma of the esophagus. Hyperexpression of proteins was detected by immunohistochemical methods and gene amplification and other chromosome abnormalities were studied using FISH reaction. Evaluation of EGFR status showed that amplification of EGFR gene was present in 25% cases and chromosome 7 polysomy was detected in 29.

Clinical significance of hyperexpression of epidermal growth factor receptors (EGFR and HER-2) in esophageal squamous cell carcinoma.

Immunohistochemical study of marker expression in primary tumors of patients with esophageal squamous-cell carcinoma was carried out in order to evaluate prognostic significance of EGFR and HER-2 levels in the tumors. Hyperexpression of EGFR and HER-2 in the tumors is an important marker for the analysis of prognosis and clinical course of the disease. A relationship between high levels of EGFR and HER-2 in the tumors of patients with esophageal squamous-cell carcinoma and intravascular tumor invasion (p=0.

Simultaneous operations in thoraco-abdominal clinical oncology.

Objective: To increase radical operability of cases with synchronous multiple primary malignant tumours (SMPTM) of the thorax and abdomen, and of cancer patients with concomitant severe heart disease simultaneous operations are implemented in the clinical practice.

Methods: Twenty-seven simultaneous operations for SMPMT (17) and for cancers of different sites and concomitant cardiac disease (10) were performed at the Surgical Department of Thoraco-Abdominal Oncology, N.N.
