INTRODUCTION: Cancer rates are rising in low- and middle-income countries. While point-of-care ultrasound is now available globally and could serve to mitigate against this rise, its use in diagnosing cancers is inconsistent in lower-resourced healthcare contexts. This proof-of-concept study investigates the feasibility of an ultrasound training concept in a low-resource setting. It evaluates whether this educational concept led to improved knowledge and application of ultrasound diagnostics, cancer screening and staging and patient care...

BACKGROUND: Cervical cancer is the leading cause of gynaecological cancer death among women in developing countries and the most preventable of all gynaecological cancers as its infectious aetiological agent, human papillomavirus (HPV), is known. The knowledge of HPV serotype distribution in a sub-region is key to the implementation of an appropriate HPV vaccination programme. AIM: To assess the prevalence of HPV-DNA, serotypes and risk-determinants among women with invasive cervical cancer (ICC) in Katsina State, Northwestern Nigeria...

BACKGROUND: Breast cancer (BC) is prevalent in Sudan, yet data on its epidemiology in Eastern Sudan is limited. This study aims to provide insights into the demographic and clinicopathologic features of BC patients treated at the East Oncology Centre (EOC) in Gadarif State, Eastern Sudan. Furthermore, we aim to identify the factors that contribute to a late-stage diagnosis. METHODS: This cross-sectional study included patients diagnosed with BC and treated in the EOC between 2016 and 2022...

BACKGROUND: Low- and middle-income countries continue to bear the burden of cervical cancer partly due to low uptake of screening services. Interventions through the media to increase demand for screening services among women of reproductive age (WRA) have not yielded the desired results mainly due to the unidirectional flow of information. The current study evaluated the use of a dialogue-based approach to community health education to improve the demand for cervical cancer screening services among WRA in rural sub-counties in Kisumu County...

BACKGROUND: Rare diseases are associated with unique challenges encountered in diagnosis, treatment and conduct of clinical research. Desmoid tumour (DT) is one such ultra-rare malignancy about which awareness among medical professionals remains limited. We developed a questionnaire to assess knowledge, attitude and practice (KAP) among medical professionals on DT. METHODS: E-Delphi method was used for the assessment of KAP for DT amongst clinical experts (experience of >/= 3 years in DT)...

The aim of this study was to determine the frequency of TP53 mutation among Pakistani head and neck cancer (HNC) patients who visited Nishtar Hospital Multan and Nishtar Institute of Dentistry (NID), Multan, Pakistan. While significant research has been conducted on the role of p53 in HNC throughout the world, this study is the first of its kind in Southern Punjab, Pakistan. A total of 242 samples (121 cases and 121 controls) were collected from Nishtar Hospital Multan and NID, Multan, Pakistan. After histopathological analysis to determine the stage type and grade of malignancy, DNA extraction and sequencing were carried out to assess any mutations in the TP53 region (exons 5-8)...

INTRODUCTION: Gross hematuria (GH) in advanced/inoperable bladder cancer patients causes significant morbidity. Patients frequently need multiple transfusions. Hypofractionated radiotherapy (RT) has been shown to be effective in symptom palliation. In this study, we explore the efficacy of various fractionation regimens in these patients. METHODS: This single institute retrospective analysis was conducted on 60 consecutive patients treated with palliative RT. Fractionation (single versus multiple) and biologically equivalent doses (BED; high ≥36 Gy versus low <36 Gy) were used to compare the efficacy of various fractionation regimens...

Discordant lymphoma (DL) is an uncommon condition in which two or more histologically different types of lymphomas are present at distinct anatomical sites in the same patient. Here, we report a case of a pediatric patient under 10 years old presenting with symptoms of general sickness with cervical lymphadenopathy, abdominal distension and an abdominal mass. Upon conducting investigations, classic Hodgkin lymphoma (CHL) was detected in the cervical lymph nodes, and high-grade B-cell non-Hodgkin lymphoma was detected in the bone marrow and abdominal mass...

INTRODUCTION: Osimertinib is more efficacious and as safe as first-generation epidermal growth factor receptor (EGFR)-directed tyrosine kinase inhibitors. However, osimertinib is not affordable for most patients in developing nations. Moreover, the minimum biologically effective dose of osimertinib may be less than the approved dose. MATERIALS AND METHODS: This was a retrospective observational multicentric study aimed to describe the efficacy (objective response rate (ORR), disease control rate (DCR), progression free survival (PFS), overall survival (OS)) and toxicity of osimertinib 80 mg orally administered less frequently than daily (ranging from every other day to once-a-week) in patients with EGFR-mutated non-small cell lung cancer...

Managing cancer under ideal conditions is a daunting prospect, to say the least. Treating cancer in conflict areas, war zones or being a refugee with cancer, facing complex political, economic and health-related threats presents a colossal global challenge. Managing such patients requires close coordination with international bodies, nongovernmental organisations and national governments, mitigating the burden of cancer care provision to patients and host countries alike.

BACKGROUND: Multilocus inherited neoplasia allelic syndrome (MINAS) is a recently coined term that describes the coexistence of two or more pathogenic variants (PVs) in cancer susceptibility genes (CSGs) in a single individual. CASE PRESENTATION: This article presents two cases of MINAS due to rare CSG combinations. The first was a 37-year-old woman carrying PVs in the mutated ataxia telangiectasia ( ATM ) and CHEK2 genes, with HER-2 positive unilateral breast cancer at 29...

Non-muscle invasive bladder cancer (NMIBC) is characterised by high rates of recurrence and progression, requiring substantial healthcare resources. In Latin America, the incidence of NMIBC is set to increase due to an aging population and lifestyle changes. To better understand the current challenges for NMIBC treaters and patients, a mixed-methods approach was leveraged combining secondary research with qualitative interviews from healthcare providers in Brazil, Colombia, Mexico and Argentina. Our analysis found that significant challenges persist across the region, particularly due to Bacillus Calmette-Guérin shortages, inconsistent adherence to clinical guidelines and significant socioeconomic disparities for patients accessing healthcare services...

BACKGROUND: Gastric cancer (GC) is the fourth leading cause of cancer deaths globally. There is a paucity of real-life data on GC in Brazil. Our study aimed to evaluate survival trends in gastric adenocarcinoma (GA) in a large cancer center in Brazil during 2000-2017. METHODS: Based on our Hospital Cancer Registry Database, all individuals diagnosed with GA between 2000 and 2017, and treated at A.C. Camargo Cancer Center, were retrospectively included. The primary objectives were to describe the patient demographics, clinicopathological characteristics, treatment modalities and survival trends during four separate periods of diagnosis (2000-2004; 2005-2009; 2010-2014 and 2015-2017)...

The malignant transformation of mature cystic teratomas during pregnancy is a rare occurrence in medical literature. In this case report, we present a remarkable instance of mucinous intestinal adenocarcinoma arising from a mature ovarian cystic teratoma diagnosed during pregnancy. This is among the few reports detailing the effective use of the FOLFOX 6 chemotherapy regimen for treating this type of intestinal cancer. Furthermore, we emphasize the immunohistochemical results that confirm the colorectal histological origin...

Vitiligo is a disease characterised by the autoimmune destruction of melanocytes, manifesting as depigmentation of the skin. We present the case of a female patient with a history of breast cancer who developed vitiligo in the area of the treatment field 12 months after the end of radiotherapy. It has been reported in the literature that vitiligo can occur in patients with a history of vitiligo after radiotherapy, attributable to the Koebner phenomenon, where some treatments can induce new vitiligo lesions in the patient...

Breast cancer (BC) is a global concern, with Peru experiencing a high incidence and mortality. Trastuzumab, a crucial treatment for human epidermal growth factor receptor 2-positive BC, is administered intravenously or subcutaneously (SC). This study evaluates the costs associated with both methods at Peru's Instituto Nacional de Enfermedades Neoplásicas. Real data indicate that SC administration reduces treatment costs by approximately S/15,049.09. Cross-continental comparisons highlight a global trend favouring SC administration for efficiency and cost-effectiveness...

BACKGROUND: Cervical cancer continues to be a major health issue in low- and middle-income countries (LMICs). Despite increasing access to screening, access to precancer treatment remains a significant challenge in LMICs, highlighting a need for innovative, accessible and resource-appropriate treatment approaches, including self-administered therapies. METHODS: A cross-sectional mixed-methods study was conducted among men aged 25-65 with a current female partner in Kisumu County, Kenya...

BACKGROUND AND AIM: Docetaxel, oxaliplatin, leucovorin and 5-fluorouracil (FLOT) may improve overall survival (OS) in patients with locally advanced gastric and gastroesophageal cancer. Our study aims to determine the pathological response in these patients with the FLOT chemotherapy in the Neoadjuvant setting. This is the first study conducted in our country. METHODS: We conducted a retrospective cross-sectional study from March 2018 to December 2020. After ethical review committee approval, all patients who fulfilled the inclusion criteria and received treatment at our tertiary care center were included in the study...

BACKGROUND: More than 50% of people with advanced cancer suffer from cancer-related cachexia (CC) - a major contributor to morbidity and mortality. Despite the lack of local guidelines on CC diagnosis and management in Uganda, the American Society of Clinical Oncology (ASCO), the European Society for Medical Oncology (ESMO) and the Global Leadership Initiative on Malnutrition (GLIM) developed guidelines on CC screening and management. However, the level of knowledge on CC and compliance with the available guidelines among Ugandan oncology health professionals is unknown...
