Background: To present the population-based cancer statistics for Khyber Pakhtunkhwa (KP), Pakistan, an incidence study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC) in Lahore, Pakistan, in 2023., Methods: Records from various centres on new cancers diagnosed among residents of KP between January and December 2020 were gathered. Both active and passive methods of data collection were applied, and the information was saved in a central repository at SKMCH&RC. The incidence rates were computed by age group and sex and presented per 100,000 population., Results: Among children (0-14 years), the Age-Standardised Incidence Rate (ASIR) was 4.0 in girls and 6.1 in boys, and haematologic malignancies were more prevalent; in adolescents (15-19 years), the ASIR was 7.7 in females, 9.4 in males, and bone tumours, haematologic malignancies, and neurological cancers were prominent; in adult females (> / = 20 years), the ASIR was 84.9, and cancers of the breast, digestive system, and reproductive organs were predominant; and adult males, the ASIR was 73.0, and cancers of the gastrointestinal tract, lip/oral cavity/pharynx, prostate, and Non-Hodgkin Lymphoma (NHL) were common., Conclusions: It is crucial to investigate the aetiology of these diseases at the community level because dietary elements, infectious diseases, and tobacco use all appear to be significant contributors. Prospective studies could play a key role in highlighting the factors linked to these diseases. Therefore, cancer registration must continue in conjunction with the exploration of risk factors., (© 2023. BioMed Central Ltd., part of Springer Nature.)

We implemented preprocedure severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing for cancer patients. The overall positivity rate was 0.3%. Preprocedure testing may be limited to operative procedures as community rates of SARS-CoV-2 exceed 7%. Nonoperative aerosol-generating procedures may be performed without preprocedure testing, wearing the appropriate personal protective equipment.

Purpose: The COVID-19 pandemic has affected health care systems worldwide, resulting in critical shortages of essential items and materials. The available guidelines are of little use for cancer hospitals in low-income and low-middle-income countries. They have been designed for community hospitals serving in a centralized health care network. This study aimed to draft and field test a framework to establish a list of essential supplies that should be stockpiled for subsequent waves of the COVID-19 virus by a tertiary care cancer hospital in a low-middle-income country., Materials and Methods: A model was formulated using the consumption trends during the peak month of the first wave of COVID-19 infection to compile a list of essential materials and supplies. Furthermore, costing analyses were conducted to determine the financial benefits of stockpiling., Results: A proposed list of items to stockpile, including personal protective equipment, radiology supplies, laboratory reagents, medication, and oxygen, was shared with the hospital administration. However, the hospital administration only accepted the proposals for stockpiling personal protective equipment and oxygen., Conclusion: This paper provides a framework and strategies that cancer hospitals and health care systems can modify and use as per individual, institutional requirements and specifications for stockpiling essential items during the COVID-19 or other similar pandemics.

The non-enzymatic interaction of sugar and protein resulting in the formation of advanced glycation end products responsible for cell signaling alterations ultimately leads to the human chronic disorders such as diabetes mellitus, cardiovascular diseases, cancer, etc. Studies suggest that AGEs upon interaction with receptors for advanced glycation end products (RAGE) result in the production of pro-inflammatory molecules and free radicals that exert altered gene expression effect. To date, many studies unveiled the potent role of synthetic and natural agents in inhibiting the glycation reaction at a lesser or greater extent. This review focuses on the hazards of glycation reaction and its inhibition by natural antioxidants, including polyphenols., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Cancer patients' preferences regarding disclosure of prognosis and end-of-life care remain under-reported from low- and middle-income countries where cancer poses an increasing demand on scarce healthcare resources. A better knowledge of these preferences can help in achievement of shared treatment goals., Aim: To survey preferences of adult cancer patients regarding disclosure of prognosis and end-of-life care, Design: A multidimensional questionnaire was developed to survey consecutively sampled patients. A fifth of the participants completed a repeat survey 3 months later., Setting/participants: Adult patients at a specialist cancer center in Pakistan., Results: In total, 520 patients were surveyed initially (participation rate 98.6%) and 100 completed the repeat survey. Three in five respondents wanted a healthcare provider to give them detailed information about their prognosis and life expectancy. Those who wanted information withheld were significantly more likely to be female, to have a lower socioeconomic status, or to have lung cancer. Only two in five patients agreed that they wanted to die at home and more than 90% wanted all possible care till end-of-life. Yet, a little over half also agreed that they did not wish to be placed on a ventilator. In rank ordering preferences about end-of-life, respondents ranked "religious wellbeing" as the highest and "avoiding inappropriate prolongation of dying" as the lowest of six options., Conclusion: A majority of adult cancer patients surveyed in this study wanted a truthful disclosure about their disease prognosis and expressed a preference for hospital-based care at end-of-life. Healthcare providers should find ways to tailor prognostic information to patients' expressed information needs., (© The Author(s) 2016.)

Objectives: To estimate the population-level cancer estimates for the Lahore district, which is part of the Punjab Cancer Registry (PCR), Pakistan. The average population per year of Lahore was estimated at 9.8 million in 2010-2012., Design: A cross-sectional study., Setting: The Registry has 19 collaborating centres in Lahore that report their data to the Central Office located within a tertiary care cancer treatment facility in Lahore, Pakistan., Participants: Patients belonging to Lahore, of any age-group, and diagnosed with cancer in 2010-2012, were included in the study. They were followed up between July and October 2015 to determine their vital status., Outcome Measures: Summaries were generated for gender, the basis of diagnosis, diagnoses and deaths. The Age-Standardized Incidence Rates (ASIR) were computed per 100 000 population, by gender and cancer site. Five-year age categories were created from 0-4 until 70-74, followed by 75+ years. Death counts were reported by site., Results: Between 2010 and 2012, in Lahore, a total of 15 840 new cancers were diagnosed in 43% male patients and 57% female patients; 93.5% were microscopically confirmed and 6.5% non-microscopically. In females, the ASIR was 105.1 and in males, it was 66.7. ASIRs of leading cancers among women were breast 47.6, ovary 4.9 and corpus uteri 3.6, whereas among men they were prostate 6.4, bladder 5.0, and trachea, bronchus and lung 4.6. A total of 5134 deaths were recorded., Conclusions: In Lahore, the ASIR was higher in women than in men. Among women and men, breast cancer and prostate cancer, respectively, were the leading cancer types. These estimates can be used for health promotion and policymaking in the region., (Published by the BMJ Publishing Group Limited.

Background: Patients suffering from malignancies often undergo serial positron emission tomography - computed tomography (PET-CT) scans, using 2-deoxy-2-[18F] fluoro-D-glucose (FDG) for diagnosis and follow up. This principle may also be applied to benign conditions as inflammatory cells take up increased amounts of FDG as well. The aim of our study was to retrospectively review the cytological diagnoses made at EUS-FNA of FDG-avid PET-CT lesions in patients with a history of cancer and to determine whether the cause of FDG-avidity was neoplastic or benign., Methods: We used the endoscopy database to extract clinical information on all patients with malignancies who underwent EUS-FNA to obtain tissue from FDG-avid nodes seen on PET-CT at our institution from 2009 - 2012. All patients who were referred for EUS-FNA after their scans were included. Those who had contraindications to endoscopic procedures were excluded., Results: The most common location of positive lymph nodes was the subcarinal region (46%). A definitive diagnosis was obtained in 87.8% cases, of which 51.2% had a diagnosis of malignancy confirmed on cytology, while 36.5% were benign. Out of these, 29% had granulomatous inflammation. In 12.2% of cases no definitive diagnosis was obtained., Conclusion: Our results show that great caution should be exercised when evaluating FDG-avid PET-CT nodes in patients with known malignant disease, as a significant proportion of these lesions may be benign, particularly in geographic locations with a high background prevalence of granulomatous inflammation.

Previously, we reported that human p53 is functionally inactivated by S-glutathionylation at Cys-141 during oxidative and DNA-damaging treatments. Here, we describe the presence of thiolated p53 and the dynamic nature of this modification in human tissues using unique and specific polyclonal antibodies raised against a 12-residue p53 peptide bearing a mixed disulfide at Cys-141. The affinity- purified antibodies (glut-p53) were sequence-specific in that they recognized the antigenic peptide but not the unthiolated peptide or a scrambled glutathionylated peptide in ELISAs. On immunoblots, the purified antibodies did not react with native p53 or recombinant p53 (rp53), but readily detected the glutathionylated or cysteinylated or ethanethiol-treated rp53 only under nonreducing conditions. Untreated HCT116 cells showed low levels of glut-p53, which increased markedly after H(2)O(2), diamide, cisplatin, and doxorubicin treatments. Glut-p53 levels decreased sharply after cells were passed into oxidant-free medium, suggesting efficient dethiolation. The mutant p53 present in HT29 and T47D human cancer cells was also recognized. In vitro, the glut-p53 was rapidly degraded by rabbit reticulocyte lysates. Human prostate and prostate cancer tissues showed an abundant presence of glut-p53 in luminal epithelium, a site well known to generate ROS. Melanoma and colon cancer samples were also positive for glut-p53. The availability of the thiolation-specific antibodies should enhance our knowledge of p53 regulation in redox-perturbed states found in various diseases including cancer., (Copyright 2010 Elsevier Inc.
