Objective: This study aimed to assess the palliative care knowledge among the registered nurses working in tertiary care hospital in Madhya Pradesh. Methods and materials: A prospective cross-sectional study was conducted on 160 registered nurses working in different departments in tertiary care hospital in Madhya Pradesh, who were selected through a purposive sampling technique. The data was collected through an online questionnaire for the socio-demographic variables and validated a self-report questionnaire to measure the knowledge of health care professionals in palliative care and the data was analysed by IBM-SPSSv26. Results: A total of 160 participants enrolled in the study. Basic knowledge care was quite high among the samples (83.75%). Item 1,2 of pain in palliative care was quite high (83.43%) and item 3,4,5 has (22%) only, overall management of pain knowledge was (47%) which is on the lower side. The use of Morphine was 31.04%, Dyspnoea Management it was 38.33%, and in the communication of prognosis, it was 81.56%. Resuscitation knowledge was 46.85%, Psycho spiritual was 24.06% and Bereavement care was 69%. Conclusion: One of the biggest challenges in providing excellent palliative care is that nurses don’t know enough about it. Therefore, improving the quality of palliative care services provided to patients could be accomplished by increasing their knowledge through in-service education and retraining on the job.

Breast cancer, amongst others, commonly metastasizes to adrenals causing hypoadrenalism. However, adrenal insufficiency is a rare manifestation. We report a rare case of metastatic carcinoma breast with bilateral adrenal involvement who presented with early adrenal insufficiency. This a dreaded complication which can be avoided if prompt treatment is initiated based on strong clinical suspicion.

Abstract Water‐dispersible and fluorescence‐stable carbon quantum dots (CQDs) have been synthesized at gram scale using pyrene as carbon precursor by employing the bottom‐up approach. X‐ray diffraction, FTIR, Raman spectroscopy and UV visible spectroscopy confirm the formation of CQDs. TEM images shows that size of the CQDs ranges from 2 to 5 nm. A detailed study of their optical and fluorescence characteristics was performed. Their aqueous dispersion radiates bright yellow light under UV lamp (365 nm). The research work includes derivation of their excitation wavelength, observation of influence of dilution on fluorescence and monitoring of emission intensity for about 4 months. The CQDs can effectively recognize the presence of heavy metal ions in aqueous medium at neutral pH via fluorescence quenching.

Abstract Shiv Prasad Shrivastava Purpose The incidence of cancer has increased in India with a visible impact on the young population (aged 15–39 years). The present study aims to evaluate psychological distress among Indian adolescents and young adults (AYAs) with solid cancer using the National Comprehensive Cancer Network (NCCN) distress thermometer. Methods The demographic and clinical characteristics of AYAs patients (age 15–39 years) with cancer were recorded. Assessment of psychological distress of patients using the NCCN distress thermometer was performed at three time points over a period of 3 months. Distress thermometer scale and a self-administered questionnaire in English and Hindi languages was handed over to participants at three time points: at treatment commencement (T1), at 1 month, and 3 months (T2 and T3, respectively) into therapy. Results Of the 259 patients, 63% were women and 37% men; the median age was 34 years. In total, 71 (27%) were ≤ 24 years old and 188 (73%) were>24 years old. Bone sarcoma (39%) was common cancer in AYA patients aged ≤ 24 years and breast cancer (21%) in >24 years of age. The distress scores in both the groups were the highest at diagnosis (T1) followed by that measured at 1 (T2) and 3 months (T3) after diagnosis. The distress score in the age ≤ 24 years was the highest (6.7) at T1, followed by those measured at T2 (2.6) and T3 (1.1) and among age>24 years was the highest (6.6) at T1, followed by those measured at T2 (2.6) and T3 (1.2). Among AYA patients>24 years old, worry, nervousness, sadness, transportation, and sleep were the top five identified problems and in ≤ 24 years old, the top identified problems were worry, financial support, sleep, nervousness, and sadness. Conclusion Adolescents and young adults experience some level of distress associated with the cancer diagnosis, effects of the disease, treatment regardless of the stage and various transitions throughout the trajectory of the disease. The distress thermometer is an easy and useful tool for the assessment of psychological distress in AYA cancers. Early identification of distress burden with the distress thermometer leads to effective interventions in patients with cancer which could improve outcomes including survival in AYAs with cancer in India.

Background Coronavirus disease 2019 (COVID-19) pandemic had an overwhelming impact on health care worldwide. Cancer patients represent a subgroup that is vulnerable and is under high risk. It is, therefore, necessary to analyze factors that predict outcomes in these patients so that they can be triaged accordingly to mitigate the effects of COVID-19 on cancer management. To date, the impact of COVID-19 on cancer patients remain largely unknown. Methods Data of 291 cancer patients undergoing active treatment from March 23 to August 15, 2020 were retrospectively reviewed; the incidence, demographic and clinical characteristics, treatment, and outcomes of cancer patients infected by COVID-19 were included in the analysis. Discussion During the index period (March 23–August 15, 2020), 4,494 confirmed cases of COVID-19 were admitted at our institute. In the department of medical oncology out of 578 patients presented to outpatient department, 291 patients were admitted for active treatment. Considering the cancer patients, infection rate was 7.9% (23/291) and mortality 13% (3/23). Median age was 40 years and the majority of patients were male (60%). The most common cancer type was acute lymphoblastic leukemia presented at various stages of treatment. Twenty patients (86.9%) were discharged after full clinical recovery and negative real-time polymerase chain reaction on a nasopharyngeal swab. Anticancer treatment was modified according to the type of cancer under intensive surveillance. Conclusion Although mortality rate in COVID-19 cancer patients is elevated, our results support the feasibility and safety of continuing anticancer treatment during pandemic by endorsing consistent preventive measures, but however should be modified based on the type and prognosis of cancer.

Brightly fluorescent Carbon Dots (CDs) were synthesized by green hydrothermal method using commonly available biomass (Aloe vera) as carbon precursor. Their physiochemical and optical characterization was done by standard microscopic and spectroscopic techniques. Photophysical features of their aqueous dispersion were investigated in detail. The influence of wide pH range (2–12), high ionic load (2M) and temperature on their photoluminescence behavior was investigated. Their in-vitro cytotoxicity examination was conducted on Human Cervical Cancer Cells (HeLa) using MTT assay. Testing of their ion-recognition property for common metal ions was done in aqueous medium. These CDs exhibited preferential interaction with Fe3+ over other tested metal ions, without any functionalization. Interaction between CDs and Fe3+ was analyzed in the light of Density Functional Theory (DFT). The work demonstrates that these CDs are acting as nanoprobe for Fe3+ and sensing it at ultra-trace level (5 nM).

Background Tumor mutational burden (TMB), defined as the number of somatic mutations per megabase of interrogated genomic sequence, demonstrates predictive biomarker potential for the identification of patients with cancer most likely to respond to immune checkpoint inhibitors. TMB is optimally calculated by whole exome sequencing (WES), but next-generation sequencing targeted panels provide TMB estimates in a time-effective and cost-effective manner. However, differences in panel size and gene coverage, in addition to the underlying bioinformatics pipelines, are known drivers of variability in TMB estimates across laboratories. By directly comparing panel-based TMB estimates from participating laboratories, this study aims to characterize the theoretical variability of panel-based TMB estimates, and provides guidelines on TMB reporting, analytic validation requirements and reference standard alignment in order to maintain consistency of TMB estimation across platforms.Methods Eleven laboratories used WES data from The Cancer Genome Atlas Multi-Center Mutation calling in Multiple Cancers (MC3) samples and calculated TMB from the subset of the exome restricted to the genes covered by their targeted panel using their own bioinformatics pipeline (panel TMB). A reference TMB value was calculated from the entire exome using a uniform bioinformatics pipeline all members agreed on (WES TMB). Linear regression analyses were performed to investigate the relationship between WES and panel TMB for all 32 cancer types combined and separately. Variability in panel TMB values at various WES TMB values was also quantified using 95% prediction limits.Results Study results demonstrated that variability within and between panel TMB values increases as the WES TMB values increase. For each panel, prediction limits based on linear regression analyses that modeled panel TMB as a function of WES TMB were calculated and found to approximately capture the intended 95% of observed panel TMB values. Certain cancer types, such as uterine, bladder and colon cancers exhibited greater variability in panel TMB values, compared with lung and head and neck cancers.Conclusions Increasing uptake of TMB as a predictive biomarker in the clinic creates an urgent need to bring stakeholders together to agree on the harmonization of key aspects of panel-based TMB estimation, such as the standardization of TMB reporting, standardization of analytical validation studies and the alignment of panel-based TMB values with a reference standard. These harmonization efforts should improve consistency and reliability of panel TMB estimates and aid in clinical decision-making.

Background: Gastrointestinal tract (GIT) is the most common extranodal site for non-Hodgkin's lymphoma (NHL) and constitutes about 10%-15% of all NHL. This was a prospective study to evaluate the epidemiological, clinicopathological characteristics, and treatment outcome of primary GIT diffuse large B-cell lymphoma (PGIL). Materials and Methods: Newly diagnosed patients of PGIL with DLBCL histology were eligible. Lugano staging system was used. All patients were treated with prephase treatment (1 mg vincristine and 100 mg prednisolone) followed by CHOP-based chemotherapy (with or without rituximab) as definitive treatment. Results: A total of 21 patients of PGIL were diagnosed. The median age was 46 years (range: 27–69 years) with male:female ratio of 2:1. Dull aching abdominal pain was the most common presenting complaint. Stomach was the most common site involved (52.4%, n = 11) followed by the colon (23.8%, n = 5). The estimated median survival in patients with Stage IV disease was significantly lower as compared to patients with localized disease (Stage I and II) (6.23 months vs. 23.4 months; P = 0.04). Patients, who did not achieve complete response (CR), had 15.5 times higher risk of death, as compared to those who achieved CR (P = 0.01). Conclusions: Stomach was the most common site for PGIL. Localized disease and CR after first-line chemotherapy were associated with better survival. A higher cost of rituximab was the prohibitive factor for cure in these patients.

Background: Neuroendocrine carcinoma (NEC) is a rare tumor arising from the diffuse neuroendocrine system. Most of these present in the advanced stage and palliative chemotherapy remains the only option. The prognosis remains poor with the standard chemotherapy regimen of platinum and etoposide (EP) providing modest survival benefit. Methods: The study was done for 3 years at a tertiary cancer center in South India. Patients with a diagnosis of metastatic NEC were analyzed for clinical and pathological characteristics. The treatment outcomes and prognostic factors were evaluated using appropriate statistical test. Results: A total of 114 patients of metastatic NEC satisfied the inclusion criteria and were analyzed. Gastrointestinal including hepatobiliary tract (33%) was the most common site of primary disease followed by lung (26%), genitourinary (15%), head and neck (14%), and unknown primary (9%). On analysis of pattern of metastasis, liver (65%) was the most common site followed by bone (54%) and lung (42%). The median overall survival was 11 months with a statistically significant difference between pulmonary and extrapulmonary disease (8 vs. 13 months; P = 0.003). Ki67% value was strongly associated with prognosis (hazard ratio 0.517, 95% confidence interval; 0.318–0.840, P = 0.008) whereas age, sex, and lactate dehydrogenase level did not show any relation with survival. Conclusion: The outcome of advanced NEC with standard chemotherapy remains poor. Larger studies with other therapeutic and novel agents are warranted to improve the treatment outcomes.

Summary: Intratumor mutational heterogeneity has been documented in primary non-small-cell lung cancer. Here, we elucidate mechanisms of tumor evolution and heterogeneity in metastatic thoracic tumors (lung adenocarcinoma and thymic carcinoma) using whole-exome and transcriptome sequencing, SNP array for copy-number alterations (CNAs), and mass-spectrometry-based quantitative proteomics of metastases obtained by rapid autopsy. APOBEC mutagenesis, promoted by increased expression of APOBEC3 region transcripts and associated with a high-risk APOBEC3 germline variant, correlated with mutational tumor heterogeneity. TP53 mutation status was associated with APOBEC hypermutator status. Interferon pathways were enriched in tumors with high APOBEC mutagenesis and IFN-γ-induced expression of APOBEC3B in lung adenocarcinoma cells, suggesting that the immune microenvironment may promote mutational heterogeneity. CNAs occurring late in tumor evolution correlated with downstream transcriptomic and proteomic heterogeneity, although global proteomic heterogeneity was significantly greater than transcriptomic and CNA heterogeneity. These results illustrate key mechanisms underlying multi-dimensional heterogeneity in metastatic thoracic tumors. : Roper et al. perform integrated exome, transcriptome, and quantitative proteomics analyses of metastases obtained through rapid autopsy of patients with thoracic malignancies. They identify APOBEC mutagenesis, driven by germline variants, mutant TP53, and the tumor microenvironment, and late copy-number alterations as key mechanisms underlying proteogenomic evolution and heterogeneity. Keywords: APOBEC, heterogeneity, evolution, lung adenocarcinoma, thymic carcinoma, rapid autopsy, proteogenomics, copy number alterations

Synovial sarcoma of lung is a very rare tumor accounting for 0.5% of all primary lung malignancy. It presents clinically with cough, chest pain, shortness of breath, or hemoptysis, with a mass lesion on X-ray and computerized tomography scan. Diagnosis is made by histopathology and immunohistochemistry. Here, we report a case of 48-year-old male, who presented with right-sided chest pain, cough with blood-tinged sputum, and found to have primary pulmonary synovial sarcoma of lung.

Background: T-cell prolymphocytic leukemia (T-PLL) is a rare lymphoid malignancy with dismal prognosis. Most patients have increased lymphocyte count (>1,00,000/dL) and widespread disease at presentation. Despite high response rate seen with alemtuzumab, the disease relapse is inevitable. Materials and Methods: This was a retrospective observational study done at a tertiary cancer center in South India. All patients diagnosed with T-PLL from August 2010 to July 2015 were studied for the clinical characteristics, pathological findings and treatment outcomes. Results: Seven patients were diagnosed as T-PLL over a period of 5 years. The median age at diagnosis was 51 years. In the present series, 6 patients (86%) had splenomegaly and 3 had hepatomegaly (43%). Generalized lymphadenopathy was seen in 4 (57%) patients at presentation. Skin lesions were seen in 5 (71%) patients, whereas pleural effusion was seen in only one patient (14%). All had elevated total leukocyte count, with more than 1, 00,000/dL in 4 patients. The median survival was 5 months with different chemotherapy (CT) regimens (5 patients treated with CT and 2 received best supportive care). Conclusion:T-PLL is a rare disease with no definite treatment guidelines. At present, the best outcomes are achieved if treatment with alemtuzumab is followed by stem cell transplant, but the disease invariably relapses. Countries where affordability remains a big challenge, the best approach needs to be defined beyond the monoclonal antibodies and transplant.

The Ewing sarcoma family of tumors (EFT) is a group of highly malignant small round blue cell tumors occurring in children and young adults. We report here the largest genomic survey to date of 101 EFT (65 tumors and 36 cell lines). Using a combination of whole genome sequencing and targeted sequencing approaches, we discover that EFT has a very low mutational burden (0.15 mutations/Mb) but frequent deleterious mutations in the cohesin complex subunit STAG2 (21.5% tumors, 44.4% cell lines), homozygous deletion of CDKN2A (13.8% and 50%) and mutations of TP53 (6.2% and 71.9%). We additionally note an increased prevalence of the BRCA2 K3326X polymorphism in EFT patient samples (7.3%) compared to population data (OR 7.1, p = 0.006). Using whole transcriptome sequencing, we find that 11% of tumors pathologically diagnosed as EFT lack a typical EWSR1 fusion oncogene and that these tumors do not have a characteristic Ewing sarcoma gene expression signature. We identify samples harboring novel fusion genes including FUS-NCATc2 and CIC-FOXO4 that may represent distinct small round blue cell tumor variants. In an independent EFT tissue microarray cohort, we show that STAG2 loss as detected by immunohistochemistry may be associated with more advanced disease (p = 0.15) and a modest decrease in overall survival (p = 0.10). These results significantly advance our understanding of the genomic and molecular underpinnings of Ewing sarcoma and provide a foundation towards further efforts to improve diagnosis, prognosis, and precision therapeutics testing.

Neuroblastoma is one of the most genomically heterogeneous childhood malignances studied to date, and the molecular events that occur during the course of the disease are not fully understood. Genomic studies in neuroblastoma have showed only a few recurrent mutations and a low somatic mutation burden. However, none of these studies has examined the mutations arising during the course of disease, nor have they systemically examined the expression of mutant genes. Here we performed genomic analyses on tumors taken during a 3.5 years disease course from a neuroblastoma patient (bone marrow biopsy at diagnosis, adrenal primary tumor taken at surgical resection, and a liver metastasis at autopsy). Whole genome sequencing of the index liver metastasis identified 44 non-synonymous somatic mutations in 42 genes (0.85 mutation/MB) and a large hemizygous deletion in the ATRX gene which has been recently reported in neuroblastoma. Of these 45 somatic alterations, 15 were also detected in the primary tumor and bone marrow biopsy, while the other 30 were unique to the index tumor, indicating accumulation of de novo mutations during therapy. Furthermore, transcriptome sequencing on the 3 tumors demonstrated only 3 out of the 15 commonly mutated genes (LPAR1, GATA2, and NUFIP1) had high level of expression of the mutant alleles, suggesting potential oncogenic driver roles of these mutated genes. Among them, the druggable G-protein coupled receptor LPAR1 was highly expressed in all tumors. Cells expressing the LPAR1 R163W mutant demonstrated a significantly increased motility through elevated Rho signaling, but had no effect on growth. Therefore, this study highlights the need for multiple biopsies and sequencing during progression of a cancer and combinatorial DNA and RNA sequencing approach for systematic identification of expressed driver mutations.
