Background: Colorectal cancer (CRC) is a diverse disease with various clinical, pathological and molecular features that affect tumor biological behavior, treatment response and prognosis.

Objective: The aim of this study was to evaluate the correlation between metabolic 18F-FDG PET/CT parameters (SUVmax, MTV and TLG) and CEA in recurrent and metastatic CRC and to evaluate prognostic value of metabolic 18F-FDG PET/CT parameters in recurrent and metastatic CRC.

Methods: A descriptive study of 100 patients with previously detected and surgically treated CRC referred to PET/CT with a suspicion of recurrent or metastatic CRC.

Differences in Outcomes Between Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Metastatic Breast Cancer Patients in Upper Middle-Income versus High-Income Countries: A Retrospective Study from 4 Oncology Centers.

BACKGROUND Therapeutic options for human epidermal growth factor 2 (HER2)-positive metastatic breast cancer (mBC) are developing rapidly. This study aimed to determine the differences in the survival outcomes of patients with HER2-positive mBC in relation to access to anti-HER therapy at 3 oncology centers in upper-middle-income countries (UMICs) and 1 oncology center in a high-income country (HIC). MATERIAL AND METHODS We retrospectively identified 42 patients from Croatia (HIC), 71 patients from Serbia (UMIC), and 57 from Bosnia and Herzegovina (UMIC) diagnosed with HER2-positive mBC who were treated between January 2015 and December 2020.

Acceptance, effects, and tolerability in the vaccination process against SARS-CoV-2 among cancer patients in Bosnia and Herzegovina: A single-center cross-sectional study.

The SARS-CoV-2 pandemic has been the main public health issue since the end of 2019. The vaccination campaign in Bosnia and Herzegovina started in April 2021, with several vaccines available. Our study aimed to evaluate the acceptance, effects, and tolerability of vaccines against SARS-COV-2 among cancer patients.

The Oncology Association of Bosnia and Herzegovina's recommendations for fertility preservation in oncologic patients.

Malignancy is one of the major public health problems in Bosnia and Herzegovina. Along with breakthroughs in specific oncological therapy, improving the quality of life of cancer patients and management of therapy-induced side effects need to be recognized as a priority in the comprehensive cancer patient care. Fertility loss after cancer treatment is a field requiring special attention due to its various consequences on patients themselves.

Lifestyle risk factors and comorbidities of cancer patients in a country with limited resources.

Aim To investigate quality of life and exposure to lifestyle risk factors of cancer patients in Bosnia and Herzegovina and a correlation of cancer type with lifestyle risk factors. Methods This was a cross-sectional study conducted on 200 cancer patients from the Clinical Centre of the University of Sarajevo. The respondents completed an anonymous questionnaire consisting of seven sections: basic patient information, physical activity, dietary habits including alternative medicine, tobacco use, alcohol consumption, anxiety, and comorbidities.

Comparative analysis of the access to health-care services and breast cancer therapy in 10 Eastern European countries.

Aim: The aim of this study is to compare the differences in breast cancer therapy, health-care service practices, and their availability in ten European countries-Albania, Bosnia and Herzegovina, Bulgaria, Kosovo, Montenegro, Republic of North Macedonia, Croatia, Romania, Slovenia, and Republic of Serbia.

Methods: An inquire survey was conducted among oncologists in the participating countries. The questionnaire was of qualitative character and focused on several key areas as screening practices, diagnosing, treatment, and health-care procedures utilization.

Targeting HER2 expression in cancer: New drugs and new indications.

Functional activation of human epidermal growth factor receptor 2 (HER2) has been shown to strongly promote carcinogenesis, leading to the investigation of HER2-directed agents in cancers with HER2 genomic alterations. This has been best documented in the context of HER2 gene amplification in breast and gastric/gastroesophageal junction carcinomas for which several HER2-directed agents are available and have become a part of standard treatment regimens. Somatic HER2 gene mutations have been recently described at low frequency in a variety of human cancers and have emerged as a novel predictive biomarker for HER2-directed therapies.

2020 consensus guideline for optimal approach to the diagnosis and treatment of HER2-positive breast cancer in Bosnia and Herzegovina.

The HERe2Cure project, which involved a group of breast cancer experts, members of multidisciplinary tumor boards from healthcare institutions in Bosnia and Herzegovina, was initiated with the aim of defining an optimal approach to the diagnosis and treatment of HER2 positive breast cancer. After individual multidisciplinary consensus meetings were held in all oncology centers in Bosnia and Herzegovina, a final consensus meeting was held in order to reconcile the final conclusions discussed in individual meetings. Guidelines were adopted by consensus, based on the presentations and suggestions of experts, which were first discussed in a panel discussion and then agreed electronically between all the authors mentioned.

Colorectal Cancer Surgical Treatment, our Experience.

Introduction: Colorectal cancer is the third most common cancer in the male and female population. Surgical treatment of colorectal cancer is based on tumor resection and removal of associated lymph glands.

Aim: The aim of the paper is to present data from a five-year retrospective study of the surgical treatment of colorectal cancer at the Clinic for General and Abdominal Surgery at the Clinical Center of the University of Sarajevo.

AROME-ESO Oncology Consensus Conference: access to cancer care innovations in countries with limited resources. Association of Radiotherapy and Oncology of the Mediterranean Area (AROME-Paris) and European School of Oncology (ESO - Milan).

Purpose: Cancer is a leading cause of mortality worldwide. Its incidence is still increasing, particularly in developing countries. Recent progresses further strengthen the differences between low/middle and high-income countries.

Effects of adding taxane to anthracycline-based neoadjuvant chemotherapy in locally advanced breast cancer.

Aim To compare the effect of neoadjuvant chemotherapy based on taxane and/or anthracycline to the extent of an objective response in female patients with unresectable breast cancer with evaluation of the toxic profile of applied chemotherapy. Methods One hundred patients with histologically verified breast cancer, treated with neoadjuvant chemotherapy were divided into two groups: a study group A (50 patients), who had received 4 to 6 cycles of taxane-based chemotherapy, and control group B (50 patients), who had received 4 to 6 cycles of anthracyclines-based chemotherapy. Pathohistological response was evaluated after tumour excision and axillary resection at the end of chemotherapy and it was defined as pathologic complete (pCR), partial (pPR), or no response (pNR).

Expenditures on Oncology Drugs and Cancer Mortality-to-Incidence Ratio in Central and Eastern Europe.

Background: There is a steady decline in cancer mortality in Western Europe (WE), but this trend is not so obvious in Central and Eastern Europe (CEE). One of the largest discrepancies between WE and CEE is the level of investment in cancer care. The objective of our analysis was to examine the correlation between mortality-to-incidence (M/I) ratio and expenditures on oncology drugs in CEE and WE.

Bevacizumab plus paclitaxel versus bevacizumab plus capecitabine as first-line treatment for HER2-negative metastatic breast cancer (TURANDOT): primary endpoint results of a randomised, open-label, non-inferiority, phase 3 trial.

Background: The randomised phase 3 TURANDOT trial compared two approved bevacizumab-containing regimens for HER2-negative metastatic breast cancer in terms of efficacy, safety, and quality of life. The interim analysis did not confirm non-inferior overall survival (stratified hazard ratio [HR] 1·04; 97·5% repeated CI [RCI] -∞ to 1·69). Here we report final results of our study aiming to show non-inferior overall survival with first-line bevacizumab plus capecitabine versus bevacizumab plus paclitaxel for locally recurrent or metastatic breast cancer.

Predictive role of hand-foot syndrome in patients receiving first-line capecitabine plus bevacizumab for HER2-negative metastatic breast cancer.

Background: Correlations between development of hand-foot syndrome (HFS) and efficacy in patients receiving capecitabine (CAP)-containing therapy are reported in the literature. We explored the relationship between HFS and efficacy in patients receiving CAP plus bevacizumab (BEV) in the TURANDOT randomised phase III trial.

Methods: Patients with HER2-negative locally recurrent/metastatic breast cancer (LR/mBC) who had received no prior chemotherapy for LR/mBC were randomised to BEV plus paclitaxel or BEV-CAP until disease progression or unacceptable toxicity.

Selecting first-line bevacizumab-containing therapy for advanced breast cancer: TURANDOT risk factor analyses.

Background: The randomised phase III TURANDOT trial compared first-line bevacizumab-paclitaxel (BEV-PAC) vs bevacizumab-capecitabine (BEV-CAP) in HER2-negative locally recurrent/metastatic breast cancer (LR/mBC). The interim analysis revealed no difference in overall survival (OS; primary end point) between treatment arms; however, progression-free survival (PFS) and objective response rate were significantly superior with BEV-PAC. We sought to identify patient populations that may be most appropriately treated with one or other regimen.

Bevacizumab plus paclitaxel versus bevacizumab plus capecitabine as first-line treatment for HER2-negative metastatic breast cancer: interim efficacy results of the randomised, open-label, non-inferiority, phase 3 TURANDOT trial.

Background: Randomised phase 3 trials in metastatic breast cancer have shown that combining bevacizumab with either paclitaxel or capecitabine significantly improves progression-free survival and response rate compared with chemotherapy alone but the relative efficacy of bevacizumab plus paclitaxel versus bevacizumab plus capecitabine has not been investigated. We compared the efficacy of the two regimens.

Methods: In this open-label, non-inferiority, phase 3 trial, patients with HER2-negative metastatic breast cancer who had received no chemotherapy for advanced disease were randomised (by computer-generated sequence; 1:1 ratio; block size six; stratified by hormone receptor status, country, and menopausal status) to receive either intravenous bevacizumab (10 mg/kg on days 1 and 15) plus intravenous paclitaxel (90 mg/m(2) on days 1, 8, and 15) repeated every 4 weeks (paclitaxel group) or intravenous bevacizumab (15 mg/kg on day 1) plus oral capecitabine (1000 mg/m(2) twice daily on days 1-14) repeated every 3 weeks (capecitabine group) until disease progression or unacceptable toxic effects.

Safety results from a phase III study (TURANDOT trial by CECOG) of first-line bevacizumab in combination with capecitabine or paclitaxel for HER-2-negative locally recurrent or metastatic breast cancer.

Background: We report safety data from a randomised, phase III study (CECOG/BC.1.3.

Phase III, open-label, randomized study comparing concurrent gemcitabine plus cisplatin and radiation followed by adjuvant gemcitabine and cisplatin versus concurrent cisplatin and radiation in patients with stage IIB to IVA carcinoma of the cervix.

Purpose: To determine whether addition of gemcitabine to concurrent cisplatin chemoradiotherapy and as adjuvant chemotherapy with cisplatin improves progression-free survival (PFS) at 3 years compared with current standard of care in locally advanced cervical cancer.

Patients And Methods: Eligible chemotherapy- and radiotherapy-naive patients with stage IIB to IVA disease and Karnofsky performance score ≥ 70 were randomly assigned to arm A (cisplatin 40 mg/m(2) and gemcitabine 125 mg/m(2) weekly for 6 weeks with concurrent external-beam radiotherapy [XRT] 50.4 Gy in 28 fractions, followed by brachytherapy [BCT] 30 to 35 Gy in 96 hours, and then two adjuvant 21-day cycles of cisplatin, 50 mg/m(2) on day 1, plus gemcitabine, 1,000 mg/m(2) on days 1 and 8) or to arm B (cisplatin and concurrent XRT followed by BCT only; dosing same as for arm A).
