Global Landscape of the Attack of Predatory Journals in Oncology.

PURPOSE: Open-access publishing expanded opportunities to give visibility to research results but was accompanied by the proliferation of predatory journals (PJos) that offer expedited publishing but potentially compromise the integrity of research and peer review. To our knowledge, to date, there is no comprehensive global study on the impact of PJos in the field of oncology. MATERIALS AND METHODS: A 29 question-based cross-sectional survey was developed to explore knowledge and practices of predatory publishing and analyzed using descriptive statistics and binary logistic regression. RESULTS: Four hundred and twenty-six complete responses to the survey were reported. Almost half of the responders reported feeling pressure to publish from supervisors, institutions, and funding and regulatory agencies. The majority of authors were contacted by PJos through email solicitations (67.8%), with fewer using social networks (31%). In total, 13.4% of the responders confirmed past publications on PJo, convinced by fast editorial decision time, low article-processing charges, limited peer review, and for the promise of academic boost in short time. Over half of the participants were not aware of PJo detection tools. We developed a multivariable model to understand the determinants to publish in PJos, showing a significant correlation of practicing oncology in low- and middle-income countries (LMICs) and predatory publishing (odds ratio [OR], 2.02 [95% CI, 1.01 to 4.03]; P = .04). Having previous experience in academic publishing was not protective (OR, 3.81 [95% CI, 1.06 to 13.62]; P = .03). Suggestions for interventions included educational workshops, increasing awareness through social networks, enhanced research funding in LMICs, surveillance by supervisors, and implementation of institutional actions against responsible parties. CONCLUSION: The prevalence of predatory publishing poses an alarming problem in the field of oncology, globally. Our survey identified actionable risk factors that may contribute to vulnerability to PJos and inform guidance to enhance research capacity broadly.

Challenges in the management of colorectal cancer in low- and middle-income countries.

AIM: This narrative review aims to describe colorectal cancer (CRC) management landscape in low- and middle-income countries (LMICs), presenting the most recent and relevant papers on the topic. As a secondary aim, the authors suggest new ways of improving CRC patient care in LMICs. BACKGROUND: Several studies show that the incidence of colon cancer in low- and middle-income countries (LMICs) is rising. In addition to the increasing incidence, lack of early detection and impeded access to optimal multidisciplinary treatment may worsen survival outcomes. CONCLUSION: Developing quality diagnostic services in the proper health context is crucial for early diagnosis and successful therapy of CRC patients, and applying a resource-sensitive approach to prioritize essential treatments based on effectiveness and cost-effectiveness is key to overcoming barriers in LMICs, with clinical research collaborations between high-income countries (HICs) and LMICs being a helpful strategy to improve health indicators and prevent the burnout of health workers.

The Global Landscape on the Access to Cancer Medicines for Breast Cancer: The ONCOLLEGE Experience.

There is a growing global debate over barriers affecting the timely access to innovative anticancer therapies. Access to medicines is often traced back to the issue of costs: however, more commonly, the distance between valuable innovative treatments and the actual treatment of patients is far beyond the mere problem of financial barriers. A comprehensive approach to understand, assess to medicines should be pursued, to dissect the determinants and formulate solutions for all patients. In this chapter, we discuss drivers of access to innovation for patients with breast cancer, based on a case study of access to HER2-diagnositcs and therapeutics yielding a global landscape analysis, based on the efforts and expertise of the global collaborative group "ONCOLLEGE".

Knowledge, Practice, and Attitudes of Physicians in Low- and Middle-Income Countries on Fertility and Pregnancy-Related Issues in Young Women With Breast Cancer.

PURPOSE: Fertility and pregnancy-related issues are highly relevant for young (≤ 40 years) patients with breast cancer. Limited evidence exists on knowledge, practice, and attitudes of physicians from low- and middle-income countries (LMICs) regarding these issues. METHODS: A 19-item questionnaire adapted from an international survey exploring issues about fertility preservation and pregnancy after breast cancer was sent by e-mail between November 2019 and January 2020 to physicians from LMICs involved in breast cancer care. Descriptive analyses were performed. RESULTS: A total of 288 physicians from Asia, Africa, America, and Europe completed the survey. Median age was 38 years. Responders were mainly medical oncologists (44.4%) working in an academic setting (46.9%). Among responders, 40.2% and 53.8% reported having never consulted the available international guidelines on fertility preservation and pregnancy after breast cancer, respectively. 25.0%, 19.1%, and 24.3% of responders answered to be not at all knowledgeable about embryo, oocyte, or ovarian tissue cryopreservation, respectively; 29.2%, 23.6%, and 31.3% declared that embryo, oocyte, and ovarian tissue cryopreservation were not available in their countries, respectively. 57.6% of responders disagreed or were neutral on the statement that controlled ovarian stimulation can be considered safe in patients with breast cancer. 49.7% and 58.6% of responders agreed or were neutral on the statement that pregnancy in breast cancer survivors may increase the risk of recurrence overall or only in those with hormone receptor-positive disease, respectively. CONCLUSION: This survey showed suboptimal knowledge, practice, and attitudes of physicians from LMICs on fertility preservation and pregnancy after treatment completion in young women with breast cancer. Increasing awareness and education on these aspects are needed to improve adherence to available guidelines and to promote patients' oncofertility counseling.

Adequacy of Surgical Pathology Reports of Colorectal Carcinoma and Its Significance.

Introduction Colorectal cancer is the fifth most common cancer in the world. For loco-regionally confined disease surgery is the definitive treatment. An adequate surgical pathology report is mandatory for the selection of adjuvant therapy. The objective of this study is to analyze whether adequate information is provided or not in the surgical pathology reports of colorectal carcinoma as according to College of American Pathologists (CAP) guidelines. Method This is a cross-sectional study carried out in the Department of Clinical Oncology, Jinnah Postgraduate Medical Center (JPMC) Karachi, tertiary care hospital in Pakistan. The duration of the study was from February 2020 to January 2021. A total of 153 surgical pathology reports issued by 11 different hospital-based laboratories after definitive surgery was assessed to look at its concordance rate with the checklist adapted from the CAP guidelines. Results Out of 153 surgical pathology reports, clinical information was provided in 72.5% of reports. Details of tumor extension were present in 88.2%, tumor margin in 75%, surgical procedure in 79%, and tumor deposits in 39.2% of reports. Macroscopic details including tumor perforation and evaluation of mesorectum were documented in 51.6% and 53.5% of the reports respectively. Details regarding perineural invasion along with lymphovascular invasion were present in 81.6% and 93% of the reports, respectively. The treatment effect was documented in only 25% of reports and regional lymph node status has been described in 85% of reports. Parameters described in all surgical pathology reports were: tumor site, tumor type, histologic type, and histologic grade. The pathological stage of the disease was documented in 91.5% of the reports. Conclusion This study concluded that surgical pathology reports of the majority of pathology laboratories were not fully adhered to the checklist provided by the CAP guidelines. This will affect post-operative management along with the prediction of disease prognosis.

Early postoperative recurrences for colon cancer: Results from a Pakistani rural cohort.

OBJECTIVES: We conducted this study to determine the factors associated with early postoperative recurrence in colon cancer patients treated with curative intent. METHODS: All consecutive patients who underwent curative resection for colon cancer between January 2014 and December 2016 were reviewed. All patients received either adjuvant chemotherapy or follow-up at the Bannu Institute of Nuclear Medicine Oncology and Radiotherapy (BINOR). The patients lived in rural areas of southern Khyber Pakhtunkhwa province. RESULTS: We enrolled 72 patients, 28 of whom experienced a postoperative recurrence within 2 years (early recurrence). In univariate analysis, postoperative early relapse was significantly correlated with advanced age (>60 years, p = 0.030), nodal status (p = 0.012), pathological stage (p = 0.013), number of nodes removed (p < 0.001), and perineural invasion (p = 0.044). In multivariate analysis, age more than 60 years (p = 0.031) and fewer than 12 lymph nodes removed (p = 0.003) were independent predictors for early recurrence. The liver was the most common site of recurrence (42.8%) in this study. CONCLUSION: Our results showed that advanced age and the removal of fewer than 12 lymph nodes during surgery were significant predictors for early postoperative recurrence. Identification of high-risk patients during follow-up with enhanced therapeutic modalities can improve disease-free survival.

The Potential of PI3K/AKT/mTOR Signaling as a Druggable Target for Endometrial and Ovarian Carcinomas.

AIMS: In this narrative review, we summarize the role and significance of PI3K-AKTmTOR (PAM) pathway in ovarian and endometrial cancers, providing the most recent and relevant literature on the topic and addressing options for targeting PAM along with future perspectives of drug development. BACKGROUND: Alterations of the PAM-pathway are common in both endometrial and ovarian cancers, and are described in specific histology-defined subtypes. PAM seems to be involved in critical steps of endometrial and ovarian carcinogenesis, often mechanistically involved in the acquisition of a phenotype of treatment resistance, which could be targetable. However, early clinical trials with PAMinhibitors (PAMi) have provided disappointing results, particularly when non isoform-specific inhibitors were tested in unselected populations, accompanied by an adverse safety profile. Since then, more encouraging observations have been collected when targeting specific isoforms of PAM proteins with more selective drugs, resulting in encouraging activity and more manageable toxicity. CONCLUSION: Although the rationale of inhibiting the PAM-pathway has been demonstrated in several promising preclinical studies, no Phase III clinical trial is available to demonstrate a significant benefit of PAM-inhibitors. A way to manage targeted agents is to tailor their use to particular subpopulations most likely to obtain a considerable benefit, namely pursuing an individualized, precision-medicine approach.

Smokeless tobacco use and risk of oral cavity cancer

Background/aim/AIM: Smokeless tobacco has been associated with oral cavity cancer for several decades. The incidence of oral cavity cancer is higher in some parts of the world especially South and South-East Asia including Pakistan. The aim of current study was to evaluate the risk of oral cavity cancer among smokeless tobacco users in our country. Materials and methodsAND METHODS: A case-control study was conducted between November 2016 and September 2017. Patients diagnosed with oral cavity cancer receiving treatment were included as cases and the attendants of various cancer patients visiting the hospital during the study period were included in the study as controls. Odds ratios (OR) and 95% confidence intervals (CI) were calculated and all reported P-values were considered significant at < 0.05. Results: The crude OR for the "ever smokeless tobacco users" among cases and controls came out to be 4.98 (95%CI; 2.76­9.01). The OR for snuff users among cases and controls was 4.82 (95%CI; 2.37­9.80) and that for betel leaf users was 4.42 (95%CI; 1.66­11.91) after adjusting for smoking and age. Conclusion: Our study provided strong evidence for snuff and betel leaf to be independent risk factors for oral cavity cancer.

Tumour sidedness and clinicopathological features of resected colon cancer in rural population of Northern Pakistan: single institutional analysis / Lateralidade tumoral e características clínico-patológicas do câncer de cólon ressecado na população rural do norte do Paquistão: análise em uma única instituição

ABSTRACT Objectives: Different clinicopathological and molecular features have been demonstrated between right and left sided colon cancers. We aimed to characterize colon cancer and sidedness among a North-Pakistani rural population diagnosed with colon cancer in our institution. Methods: Seventy patients were included in the study that received adjuvant chemotherapy at Bannu Institute of Nuclear Medicine Oncology and Radiotherapy) Bannu, Pakistan from January 2014 to December 2017. Chi-square test was used for significance of categorical variables. p-Values less than 0.05 were considered significant. Results: Mean age at diagnosis for right side colon cancer patients was 43.94 years and for left side colon cancer, it was 49.83 with no significant difference. Male patients were presented more with right (77% vs. 54%, p = 0.044) and females with predominantly left sided tumours i.e. (46% vs. 23%, p = 0.044). Right sided cancer tended to be more poorly differentiated (20% vs. 0%, p = 0.020). Mucinous adenocarcinoma was seen mostly in right sided colon cancer (37% vs. 3%, p ≤ 0.001). There were more locally advanced presentation of right side colon cancer with more node positive (83% vs. 60%, p = 0.025) and lymphovascular invasion (51% vs. 37%, p = 0.016). Sigmoid colon was the most common tumour subsite involved. Conclusion: Our study is the first report of colon cancer in a rural population in North-Pakistan. An earlier onset of tumours (44-50 years) was observed in comparison with global data.

RESUMO Objetivo: Características clínico-patológicas e moleculares distintas foram observadas em tumores de cólon no lado direito ou esquerdo. O presente estudo teve como objetivo caracterizar o câncer de cólon e sua lateralidade em uma população rural norte-paquistanesa diagnosticada com câncer de cólon nesta instituição. Métodos: O estudo incluiu 70 pacientes que foram submetidos a quimioterapia adjuvante no Instituto Bannu de Medicina Nuclear Radioterapia Oncológica (BINOR), Bannu, Paquistão, entre janeiro de 2014 e dezembro de 2017. O teste qui-quadrado foi utilizado para mensurar a significância das variáveis categóricas. Valores de p menores que 0,05 foram considerados significativos. Resultados: A média de idade ao diagnóstico entre pacientes com câncer de cólon no lado direito foi de 43,94 anos e entre aqueles com câncer de cólon no lado esquerdo, 49,83, sem diferença significativa. Os pacientes do sexo masculino apresentaram mais tumores no lado direito (77% vs. 54%, p = 0,044) e as pacientes do sexo feminino apresentaram mais tumores no lado esquerdo (46% vs. 23%, p = 0,044). Tumores mal diferenciados foram mais comumente observados no lado direito (20% vs. 0%, p = 0,020). Adenocarcinoma mucinoso foi observado principalmente em casos de tumores no lado direito (37% vs. 3%, p ≤ 0,001). A apresentação local estava mais avançada em tumores de cólon no lado direito, com mais linfonodos positivos (83% vs. 60%, p = 0,025) e invasão linfovascular (51% vs. 37%, p = 0,016). O cólon sigmoide foi o sublocal mais comum. Conclusão: O presente estudo é o primeiro relato de câncer de cólon em uma população rural no norte do Paquistão. Em comparação com dados globais, observou-se um surgimento mais precoce dos tumores (44-50 anos).

Curcumin: New Insights into an Ancient Ingredient against Cancer.

Cancer patients frequently use complementary medicine. Curcumin (CUR) and its derivates (from the extract of Curcuma longa L.) represent some of the most frequently used ones, having a long history in traditional Asian medicine. CUR was demonstrated, both in vitro and in vivo, to have significant anti-inflammatory effects, thus potentially counteracting cancer-promoting inflammation, which is a hallmark of cancer. CUR modulate a plethora of signaling pathways in cancer cells, comprising the NF-κB (nuclear factor k-light-chain-enhancer of activated B cells), the JAK/STAT (Janus-Kinase/Signal Transducers and Activators of Transcription), and the TGF-ß (transforming growth factor-ß) pathways. Furthermore, CUR confers properties of electron receptors, which destabilize radical oxygen species (ROS), explaining its antioxidant and anti-apopototic effects. Although CUR has a low bioavailability, its role in advanced cancer treatment and supportive care was addressed in numerous clinical trials. After promising results in phase I⁻II trials, multiple phase III trials in different indications are currently under way to test for direct anti-cancer effects. In addition, CUR exerts beneficial effects on cancer treatment-related neurotoxcity, cardiotoxicity, nephrotoxicity, hemato-toxicity, and others. More efficient galenic formulations are tested to optimze CUR's usability in cancer treatment. This review should provide a comprehensive overview of basic science, and pre-clinical and clinical data on CUR in the field of oncology.
