Objective. To study tubal morphological changes in different diseases of the female reproductive system and to assess its role in the histogenesis of ovarian cancer. Material and methods. Surgical materials from 77 patients were examined. In all cases, the uterine tubes were studied totally. According to morphological and clinical diagnoses, the materials obtained from the patients were divided into a few groups including, among other conditions, high-grade ovarian cancer, benign ovarian neoplasms, malignancies of other female reproductive organs, etc. Serous tubal intraepithelial carcinoma (STIC), tubal epithelial dysplasia, and other changes were assessed in each case. Results. In high-grade serous carcinoma (HGSC), there were precancer changes as dysplasia and STIC in the macroscopically intact uterine tubes in 30% of cases. The uterine tubes and ovaries were synchronously involved in 50% of cases. Such changes were absent in the fallopian tubes when the ovaries exhibited low-grade serous carcinoma, a borderline tumor or high-grade carcinoma of another histological form different from HGSC. In other malignancies of the female reproductive system, dysplasia and STIC were identified in 5 (10.9%) of 46 cases in the total examination of the uterine tubes. Conclusion. The findings support the tubal origin hypothesis for HGSC. The investigation clearly demonstrated the need for a total examination of the fallopian tubes not only in tumor lesions of the ovaries and other sites (corpus and cervix uteri, breast), but also during tumor-unassociated surgery.

Background Trastuzumab, a monoclonal antibody against human epidermal growth factor receptor 2 (HER2; also known as ERBB2), was investigated in combination with chemotherapy for first-line treatment of HER2-positive advanced gastric or gastro-oesophageal junction cancer. Methods ToGA (Trastuzumab for Gastric Cancer) was an open-label, international, phase 3, randomised controlled trial undertaken in 122 centres in 24 countries. Patients with gastric or gastro-oesophageal junction cancer were eligible for inclusion if their tumours showed overexpression of HER2 protein by immunohistochemistry or gene amplification by fluorescence in-situ hybridisation. Participants were randomly assigned in a 1:1 ratio to receive a chemotherapy regimen consisting of capecitabine plus cisplatin or fluorouracil plus cisplatin given every 3 weeks for six cycles or chemotherapy in combination with intravenous trastuzumab. Allocation was by block randomisation stratified by Eastern Cooperative Oncology Group performance status, chemotherapy regimen, extent of disease, primary cancer site, and measurability of disease, implemented with a central interactive voice recognition system. The primary endpoint was overall survival in all randomised patients who received study medication at least once. This trial is registered with ClinicalTrials.gov, number NCT01041404. Findings 594 patients were randomly assigned to study treatment (trastuzumab plus chemotherapy, n=298; chemotherapy alone, n=296), of whom 584 were included in the primary analysis (n=294; n=290). Median follow-up was 18·6 months (IQR 11-25) in the trastuzumab plus chemotherapy group and 17·1 months (9-25) in the chemotherapy alone group. Median overall survival was 13·8 months (95 CI 12-16) in those assigned to trastuzumab plus chemotherapy compared with 11·1 months (10-13) in those assigned to chemotherapy alone (hazard ratio 0·74; 95 CI 0·60-0·91; p=0·0046). The most common adverse events in both groups were nausea (trastuzumab plus chemotherapy, 197 [67] vs chemotherapy alone, 184 [63]), vomiting (147 [50] vs 134 [46]), and neutropenia (157 [53] vs 165 [57]). Rates of overall grade 3 or 4 adverse events (201 [68] vs 198 [68]) and cardiac adverse events (17 [6] vs 18 [6]) did not differ between groups. Interpretaion Trastuzumab in combination with chemotherapy can be considered as a new standard option for patients with HER2-positive advanced gastric or gastro-oesophageal junction cancer.

Malignant ascites is a common manifestation of advanced cancers, and treatment options are limited. The trifunctional antibody catumaxomab (anti-epithelial cell-adhesion molecule x anti-CD3) represents a targeted immunotherapy for the intraperitoneal (i.p.) treatment of malignant ascites secondary to epithelial cancers. In this phase II/III trial (EudraCT 2004-000723-15; NCT00836654), cancer patients (n = 258) with recurrent symptomatic malignant ascites resistant to conventional chemotherapy were randomized to paracentesis plus catumaxomab (catumaxomab) or paracentesis alone (control) and stratified by cancer type (129 ovarian and 129 nonovarian). Catumaxomab was administered as an i.p. infusion on Days 0, 3, 7 and 10 at doses of 10, 20, 50 and 150 g, respectively. The primary efficacy endpoint was puncture-free survival. Secondary efficacy parameters included time to next paracentesis, ascites signs and symptoms and overall survival (OS). Puncture-free survival was significantly longer in the catumaxomab group (median 46 days) than the control group (median 11 days) (hazard ratio = 0.254: p < 0.0001) as was median time to next paracentesis (77 versus 13 days; p < 0.0001). In addition, catumaxomab patients had fewer signs and symptoms of ascites than control patients. OS showed a positive trend for the catumaxomab group and, in a prospectively planned analysis, was significantly prolonged in patients with gastric cancer (n = 66; 71 versus 44 days; p = 0.0313). Although adverse events associated with catumaxomab were frequent, they were manageable, generally reversible and mainly related to its immunologic mode of action. Catumaxomab showed a clear clinical benefit in patients with malignant ascites secondary to epithelial cancers, especially gastric cancer, with an acceptable safety profile. © 2010 UICC. Source

There were examined 198 patients with non-small cell lung cancer (NSCLC). The levels of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (BFGF) as predictors at using neoadjuvant chemotherapy in patients with NSCLC were studied. Determination of baseline levels of VEGF and BFGF were necessary to predict the combination treatment of patients with stage III NSCLC. Source

The dynamics is presented of the rates of virus dependent diseases, in particular cervical cancer (CC), which are directly connected with the level of organization of screening and subsequent treatment of cancer. It is shown that in conditions of insurance medicine a reduction of examination rooms and female enrollment in cytology screening is observed. As a result, over the past 5 years, CC incidence in the Novgorod region increased 1.2 times, and in Russia as a whole, the proportion of such cases in female population under 29 years since 2000 increased 4.5 times (from 2.0 % to 9 %). The urgent task of cancer control is to restore examination rooms, to overcome disagreements between government institutions and medical departments, to increase coverage of women by cytology screening by means of formation of the program of individual accounting of women.
