Overview of Cancer Control in Armenia and Policy Implications.

Cancer is the second leading cause of death in Armenia. Over the past two decades, the country has seen a significant rise in cancer morbidity and mortality. This review aims to provide up-to-date info about the state of cancer control in Armenia and identify priority areas of research. The paper analyzes published literature and local and international statistical reports on Armenia and similar countries to put numbers into context. While cancer detection, diagnosis, and treatment are improving, the prevalence of risk factors is still quite high and smoking is widespread. Early detection rates are low and several important screening programs are absent. Diagnosis and treatment methods are not standardized; there is a lack of treatment accessibility due to insufficient government coverage and limited availability of essential medicines. Overall, there is room for improvement in this sector, as research is limited and multidisciplinary approaches to the topic are rare.

Incidence patterns and review of Hodgkin lymphoma in the Republic of Armenia.

Hodgkin lymphoma (HL) accounts for roughly 10% of all lymphomas and 0.6% of all malignant tumours analysed worldwide yearly. Data regarding HL in developing world are exceptionally constrained. The main objective of this research is to investigate the incidence patterns of HL within the Republic of Armenia and to portray disease distribution according to age and sex. There is a very strict evidence on the frequency of HL in Armenia. The results of our research find out that the frequency of HL in Armenia has not changed altogether over the past 15 years and is comparable to that detailed from the USA and Europe.

Treatment and Outcomes of Colorectal Cancer in Armenia: A Real-World Experience From a Developing Country.

PURPOSE: In Armenia, colorectal cancer (CRC) is one of the most frequently diagnosed cancers. It is in the third place by incidence. The aim of this study was to evaluate treatment and outcomes of CRC in Armenia during the last 9 years. MATERIALS AND METHODS: For this retrospective hospital-based study, we have collected data from two main oncology centers in Armenia: National Oncology Center and "Muratsan" Hospital of Yerevan State Medical University. The information about patients with CRC who were treated at these two centers between January 1, 2010 and July 1, 2018 was collected from the medical records. Log-rank test and Kaplan-Meier curves were used for survival analysis. Prognostic factors were identified by Cox regression. RESULTS: A total of 602 patients with CRC were involved in the final analysis. Median follow-up time was 37 months (range, 3-207 months). A total of 8.6% of patients had stage I, 32.9% stage II, 38.0% stage III, and 17.6% stage IV cancer; for 2.7% patients, the stage was unknown. The main independent prognostic factors for overall survival (OS) were tumor stage, grade, and histology. Adjuvant chemotherapy has been shown to improve survival in stage II colon cancer and stage III rectal but not in stage II rectal cancer. Radiotherapy did not yield survival improvement in stage II or III rectal cancer. Three- and 5-year OS rates were 62.9% and 51.8% for all stages combined and 79.7% and 68.5% for stages I-II, 62.5% and 48.4% for stage III, and 24.4% and 17% for stage IV respectively. CONCLUSION: As seen from our results, our survival rates are lower than those of the developed world. Additional research is needed to identify the underlying reasons and to improve patients' treatment and outcomes in Armenia.

Efficacy and safety of curcumin in combination with paclitaxel in patients with advanced, metastatic breast cancer: A comparative, randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND: The clinical efficacy of curcumin has not yet been established for the treatment of cancer, despite a large body of evidence from numerous preclinical studies suggesting the therapeutic potential of curcumin, particularly in a synergistic combination with paclitaxel. The main obstacle in using curcumin for adjunctive cancer therapy is its low bioavailability via oral administration. PURPOSE: We assessed the efficacy and safety of intravenous curcumin infusion in combination with paclitaxel in patients with metastatic and advanced breast cancer. STUDY DESIGN: A randomized, double-blind, placebo-controlled, parallel-group comparative clinical study was conducted. METHODS: A total of 150 women with advanced and metastatic breast cancer were randomly assigned to receive either paclitaxel (80 mg/m2) plus placebo or paclitaxel plus curcumin (CUC-1®, 300 mg solution, once per week) intravenously for 12 weeks with 3 months of follow-up. The primary outcome was determined based on the objective response rate (ORR), as assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). The secondary outcomes were progression-free survival (PFS), time to tumor progression (TTP), time to tumor treatment failure (TTTF), safety, and quality of life. RESULTS: The intention-to-treat (ITT) analysis revealed that the ORR of curcumin was significantly higher than that of the placebo (51% vs. 33%, p < 0.01) at 4 weeks of follow-up. The difference between the groups was even greater when only patients who had completed the treatment (61% vs. 38%, odds ratio ==2.64, p < 0.01) were included. A superior effect of curcumin vs placebo was observed in both patients who had completed the treatment and all patients included in the ITT analysis, 3 months after termination of the treatment. No other significant differences were observed between the curcumin and the placebo groups, except for fatigue (3 vs. 10 patients, respectively; odds ratio ==3.7, p = 0.05). However, the patients' self-assessed overall physical performance was significantly higher with curcumin than the placebo during the treatment and at the end of the follow-up, suggesting better tolerance in the curcumin group. CONCLUSIONS: Overall, treatment with curcumin in combination with paclitaxel was superior to the paclitaxel-placebo combination with respect to ORR and physical performance after 12 weeks of treatment. Intravenously administered curcumin caused no major safety issues and no reduction in quality of life, and it may be beneficial in reducing fatigue. ADVANCES IN KNOWLEDGE: This is the first clinical study to explore the efficacy and safety of administering curcumin intravenously in combination with chemotherapy in the treatment of cancer patients.

Availability of Essential Medicines for Pediatric Oncology in Armenia

Background: One of the main contributors in low survival rate in LMIC is the lack of availability of cancer medications for curative, supportive and palliative care. In many developing countries access to cytotoxic medicine is a major challenge. The information about the availability of essential medicines for pediatric cancer in the country is not known. The main objective of this study was to determine whether the medications used during the treatment of pediatric cancer are available in Armenia. Methods: In summer 2016 we conducted a survey in the 3 main pharmacies in Yerevan, which import pediatric cancer medications to Armenia to evaluate whether medications used during cancer treatment are officially registered and available in the country. In addition, the information on official registration was cross-checked with the Ministry of Health of the Republic of Armenia (MOH). Simultaneously, detailed information about the drugs, on type of produced drug company, doses and price intervals was confined from the price lists of the national drug importer companies. Results: The survey included 64 agents in three classes of medication: anti-neoplastics, anti-microbials, and drugs used in supportive care. All of these medications were included in the recent version of the WHO model list of essential medicines. From 30 anti-neoplastic medications on the essential medicines list 22 (73%) were officially registered in Armenia; from 19 anti-microbial drugs all were registered except caspofungin and from 15 supportive care agents 13 (87%) were registered. From registered anti-neoplastic drugs 18% and from antimicrobial drugs 33% were not available in the drug stores. Conclusion: This study showed that not all the drugs from the SIOP PODC Essential Medication list for pediatric oncology are officially registered and available in Armenia, and effective drug regulation focusing on the childhood cancer care medicine is needed for improving the situation in the country.

Identifying barriers to treatment of childhood rhabdomyosarcoma in resource-limited settings: A literature review.

We performed a literature review to examine barriers for rhabdomyosarcoma treatment in low-resource settings, and identified 29 articles from 14 middle-income countries, with none from low-income countries. Notable findings included inconsistent use of local control modalities, lack of diagnostics in some settings, and high rate of abandonment specifically in low middle-income countries. Reported limitations included lack of surgical expertise and/or radiation therapy, advanced stage of disease, and absence of health insurance. Although very poor outcomes were prevalent in several settings, good outcomes were achievable in others when multidisciplinary therapy and financial coverage of medical care were made available.

Younger age and previous exposure to radiation therapy are correlated with the severity of chemotherapy-induced thrombocytopenia.

BACKGROUND: Chemotherapy-induced thrombocytopenia (CIT) is a significant complication of cancer therapy. Data on the optimal management approaches of this morbidity in children and young adults are still limited. AIM: The aim of the study is to estimate the frequency and severity of CIT and associated clinically significant bleeding in children and young adults with solid tumours and haematologic malignancies. METHODS: For this retrospective, hospital-based study, children (0-18 y) and young adults (19-40 y) with different types of solid tumours and haematologic malignancies who received chemotherapy at the Muratsan Hospital Complex of Yerevan State Medical University were identified from the patients' database and included in the study (overall 122 patients). Thrombocytopenia was defined as a decrease of platelet count below <100 × 109/L. For assessing bleeding, WHO scale had been used. RESULTS: Overall, the whole group of patients received 430 chemotherapy cycles. During 131 (31.6%) chemotherapy cycles, patients developed CIT. The study revealed a statistically significant inversely proportional correlation between the age and the severity of CIT. Another important finding of the study was that the patients, who previously were exposed to radiation therapy, were more likely to develop CIT, than those who have not received radiation therapy (68% and 28.7%, p = 0.001). From 430 cycles of chemotherapy, 31 (7.2%) cycles reported to have bleeding events. CONCLUSION: Our study showed that clinically significant thrombocytopenia and bleeding are quite rare among children and young adults. Younger age and previous exposure to radiation therapy are positively correlated with the severity of thrombocytopenia. Larger studies are needed to investigate these findings.
