Should we prioritise proper surgical staging for patients with Atypical endometrial hyperplasia (AEH)? Experience from a single-institution tertiary care oncology centre

ObjectiveThe study aimed to evaluate the incidence of concurrent endometrial cancer (EC) and lymph node positivity in patients with Atypical Endometrial Hyperplasia (AEH) who underwent surgical staging with sentinel lymph node evaluation. It also sought to identify the risk factors associated with detecting concurrent endometrial cancer in patients with a preoperative diagnosis of AEH. Study designA retrospective study was conducted at Amrita Institute of Medical Sciences, involving 54 cases of AEH diagnosed on pre-operative biopsy specimens and undergoing staging surgery between January 1, 2015, and December 31, 2020. The study analysed demographic parameters, clinical presentations, pathological features, and clinical outcomes. Categorical variables were expressed in numbers and percentages, normal distribution data were presented as mean, and non-normal distribution data were presented as median and range. ResultsFifty-four patients diagnosed with AEH underwent surgical staging. The median age was 54 years. Final HistoPathology Report (HPR) showed 48.14 % with AEH and 51.85 % with concurrent EC. Among those with concurrent EC, 96.4 % had type I EC, and one patient was upgraded to type 2 EC. Among them, 17.8 % patients belonged to high-intermediate and high-risk categories. Patients with AEH and concurrent EC were more likely to be diabetic (OR: 3.56, p = 0.04), have a BMI ≥25 kg/m2 (OR: 1.47, p = 0.04), exhibit a thickened endometrial lining of ≥9 mm (OR: 3.13, p = 0.05) on ultrasound, and undergo preoperative biopsy at a non-oncology centre (OR: 8.33, p = 0.001) whereas experiencing heavy menstrual bleeding had a substantially lower likelihood (OR: 0.29, p = 0.01) of developing concurrent EC. ConclusionThe study revealed that more than half of patients undergoing staging surgery for AEH were found to be at risk of having concurrent EC in their final HPR. The research also pointed out that surgical staging can help identify both low-risk and high-risk ECs, which may require additional treatment. Higher BMI, diabetes mellitus, and an endometrial thickness of ≥9 mm were identified as significant risk factors for concurrent EC. Additionally, heavy menstrual bleeding was associated with a decreased risk of concurrent EC.

Assessment of quality of life in head and neck cancer patients visiting the Palliative Care outpatient department in a tertiary care oncology centre in India.

Patients with head and neck cancers (HNCs) are at an increased risk of developing functional symptoms associated with eating, speaking, and breathing along with symptoms caused by a fungating tumour (e.g., cosmetic change, malodor, and bleeding). These may substantially reduce their physical functioning and quality of life (QoL). This observational study aimed to find out the QoL in patients with HNC in a tertiary care oncology centre. A prospective observational study was conducted in adult patients diagnosed with HNC. The patients were divided depending upon their disease extent into early, advanced, and very advanced local disease. The physical, cognitive, emotional, financial and social domains were assessed using a validated Hindi version of the European Organisation for Research and Treatment of cancer (EORTC)- QoL 30 and EORTC H&N 35 at baseline and 3 months. A total of 100 patients were assessed with a mean age of 49.3 ± 12.4 years. Most of the patients had carcinoma buccal mucosa (42%) followed by carcinoma tongue (17%). The patients experienced difficulties with physical functioning and deterioration in emotional functioning. Pain and fatigue were the major problematic symptoms especially in advanced disease patients resulting in poor QoL. There was a significant improvement in various domains of QoL at 3 months follow-up in those with advanced disease. The fatigue scores at baseline and follow-up showed a positive correlation with other symptoms. Patients with HNC have a high symptom burden that leads to poor QoL. Appropriate palliative care interventions help to decrease symptom burden and prevent deterioration of their QoL in patients with HNC.

Effects of telehealth on uptake and timeliness of genetic counseling and genetic testing among patients with endometrial cancer.

e22531 Background: The COVID-19 pandemic prompted genetic counseling (GC) services to shift from in-person to remote telehealth visits. Prior studies identified that telehealth allowed uninterrupted access to cancer GC during the pandemic. However, germline genetic testing (GT) completion decreased. Before the pandemic, studies found that patients with endometrial cancer (EC) had suboptimal rates of referral to GC and GT for Lynch syndrome (LS). We sought to determine how the transition to telehealth impacted EC patients’ uptake of and timeliness to, guideline-recommended GC and GT. Methods: Adults with newly diagnosed EC who completed outpatient gynecologic oncology visits were identified from a tertiary care oncology center’s tumor registry and through retrospective review of electronic medical records. Patients were assigned to the pre-pandemic and pandemic cohorts if diagnosed 9/1/2018-3/31/2020 and 4/1/2020-12/31/2020, respectively. Patients were also assigned based on whether they met guideline-based criteria for LS GT (diagnosed under the age of 50, had abnormal MSI/IHC testing, or had a synchronous LS tumor). Chi-square, two-sample t-test, and descriptive statistics were performed, with a statistically significant p-value < 0.05. In total,443 patients with EC were included; 330 and 113 in pre-pandemic and pandemic cohorts, respectively.The pandemic cohort had higher rates of GC (24% vs 19%, p = 0.22) and GT (23% and 16%, p = 0.08). Eighty-five (25.8%) of the pre-pandemic and 23 (20.4%) of the pandemic cohorts met LS criteria for GT. Of patients who met LS criteria, the pandemic cohort also had higher rates of GC (57% vs 42%, p = 0.23) and GT (48% vs 40%, p = 0.08). Results: The median time from diagnosis to GC was 138 days for the pre-pandemic and 87 days for the pandemic cohorts (p = 0.09) The median time to GT was 144 days for the pre-pandemic and 114 days for the pandemic cohorts (p = 0.19). Of patients who met GT criteria, the pre-pandemic cohort had a median of 135 days from diagnosis to GC compared to the pandemic cohort’s median of 86 days (p = 0.37). The median time to GT was 131 days for pre-pandemic and 112 days for pandemic cohorts (p = 0.27). Conclusions: Uptake of GC and GT among patients with newly diagnosed EC, including those who met GT criteria, was higher and more timely in the pandemic cohort. While differences were not statistically significant, results suggest that telehealth may have improved delivery of GC and GT for EC patients. Overall, rates of GC and GT remain low (less than 50%), and further study of sustained effects of telehealth in this population after 2020 is needed.

Assessment of Platelet Crossmatch Results by Solid Phase Red Cell Adherence Assay among Pediatric Hemato-oncology Patients in a Tertiary Care Oncology Center

ABSTRACT Background and Objectives: This study employed platelets cross-matched by the solid-phase red cell adherence (SPRCA) method and oc-related it with posttransfusion platelet count increment in terms of corrected count increment (CCI) and percent platelet recovery (PPR) among pediatric hemato-oncology patients. It did not study subgroups of patients nor did it have a control group. This was an observational study. The objective of the study was to assess platelet crossmatch results by the SPRCA method and find its correlation with posttransfusion platelet count increment among pediatric hemato-oncology patients in a tertiary care oncology center. Methods: This was a prospective observational study performed on pediatric patients with hematological malignancies requiring platelet transfusions during August 2019–January 2020. An assessment of the response to platelet transfusion on the participants was analyzed against the crossmatch results using SPRCA to measure the response in terms of CCI and PPR. Results: A total of 80 pediatric multiply transfused patients of hematological malignancies were transfused with ABO-identical single donor platelet unit which was subsequently tested for compatibility SPRCA assay. Among a total of 80 platelet crossmatches, 86% (69/80) were found to be compatible. Among 69 patients with compatible platelet crossmatches, 91% (63/69) had adequate CCI (>7500). Among 11 patients with incompatible crossmatches, 73% (8/11) had adequate CCI, and 27% (3/11) had inadequate CCI. Statistically significant association was found between crossmatch compatibility and PPR. Conclusions: Transfusion of crossmatched platelets from the available inventory to multiply transfused patients of hematological malignancies can be an option. It is very important to assess the posttransfusion platelet responses in such patients in terms of CCI as well as PPR. The SPRCA assay is a rapid and effective method to select the compatible unit from the inventory and is feasible to implement in an oncology setup to cater the requirement of multiple platelet transfusions to patients with hematological malignancies.

Treatment outcomes in patients with Ewing sarcoma of the spine in a resource-challenged setting: 17-year experience from a single center in India

Ewing sarcoma (ES) of the spine is a rare childhood cancer with sparse literature on treatment outcomes. We aimed to describe survival outcomes and prognostic factors in patients with spinal ES treated at a single institute in a resource-challenged setting. We conducted a retrospective analysis of patients with spinal ES registered at a tertiary care oncology center between 2003–2019. Clinical patient data was retrieved from hospital records. Cox regression analysis was used to identify the association of baseline clinical parameters with event free survival (EFS) and overall survival (OS). A cohort of 85 patients was analyzed including 38 (45%) patients with metastatic disease. The median age was 15 years with 73% being male. Local therapy was administered in 62 (72.9%) patients with surgery alone in 8 (9.4%), radiotherapy alone in 36 (42.4%) and both in 18 (21.2%) patients. A higher proportion of males received local therapy than females (80.3% versus 59.1%; p = 0.049). The median EFS and OS were 20.1 and 28.6 months, respectively. On univariable analysis, age ≤ 15 years, female sex, serum albumin ≤3.5 g/dL and hemoglobin ≤11 g/dL were associated with inferior EFS while younger age, female sex, hypoalbuminemia and metastatic disease were associated with inferior OS. On multivariable analysis, only hypoalbuminemia was predictive for inferior EFS (HR:2.41; p = 0.005) while hypoalbuminemia (HR:2.06;p = 0.033) and female sex (HR:1.83; p = 0.046) were associated with inferior OS. We concluded that hypoalbuminemia confers poor prognosis in ES spine. Survival outcomes are poorer in females treated in our setting, possibly due to prevailing sex-based biases.

A study on beneficial impact of the use of medium-molecular-weight hydroxyethyl starch in granulocyte apheresis using continuous-flow cell separator Spectra Optia: A retrospective single-center study at a tertiary care oncology center.

Granulocyte transfusion is one of the best therapeutic modalities in prolonged neutropenic patients with severe bacterial/fungal infections. Granulocyte harvest using conventional acid citrate dextrose (ACD) anticoagulant (ACD-A) by apheresis is not satisfactory in comparison to the use of hydroxyethyl starch (HES), but the latter is associated with various adverse events, especially with high-molecular-weight HES. This study aimed to assess the beneficial impact of the use of medium-molecular-weight (MMW)-HES and trisodium citrate combination over ACD-A in granulocyte apheresis when using Spectra Optia. This was a retrospective study comparing granulocyte harvest results with the use of ACD or HES and trisodium citrate combination. All the donors in both the groups received single 600 μg of granulocyte colony-stimulating factor subcutaneous injection followed by 8 mg of dexamethasone tablet 10-12 h and omnacortil 60 mg orally 3 h before harvest. A number of adverse incidents, if any, were observed and noted. Donor/procedure parameters were compared using Mann-Whitney U-test/unpaired t-test. Granulocyte yield (mean: 3.29 × 1010/unit vs. 4.5 × 1010/unit in the ACD and HES groups, respectively, P ≤ 0.0001) was significantly better in the HES group. The collection efficiency was also better in the HES group (mean: 15.86% vs. 26.70% in the ACD and HES groups, respectively, P ≤ 0.0001) in the ACD and HES groups, respectively. There was no significant adverse event noted in any of these two groups. In our study, granulocytes with optimum yield can be easily harvested with Spectra Optia cell separator using 6% HES (MMW) and trisodium citrate combination with standard 12-h interval gap between mobilization and harvest. This strategy can also have no or minimal extra cost burden to patients.

Laparoscopic Sentinel Lymph Node Mapping Using NIR Fluorescence with ICG in Early Endometrial Cancer: Experience at a Tertiary Care Oncology Centre

Objective: To determine the detection rates and location of sentinel nodes as well as to determine intraoperative and postoperative surgico-pathological outcomes in endometrial cancer patients who underwent laparoscopic staging with sentinel node biopsy using ICG dye. Materials and Methods: This retrospective study was conducted in a tertiary care oncology centre, Amrita Institute of medical sciences, Kochi from April 2021 to March 2023. All cases of biopsy proven early stage endometrial carcinoma that underwent laparoscopic staging with SLN mapping using the ICG dye were included. All histological types were included, as long as the disease was confined to the uterus, clinically and on MRI. Results: A total of 80 patients were found eligible for the study. Only the patients with apparent uterine confined disease on preoperative MRI were selected for sentinel mapping, 80 % of whom had IA disease on MRI, and 20 % had IB, 13.5 % were high grade histology.The overall SLN detection rate was 93.75%, and bilateral detection rate was 92.5 %. Most common location was external iliac in 40.8% cases. Only 1 patient was found to harbour nodal micro metastasis on ultrastaging. Final histopathology identified stage IA in 63 (78.75%) patients, IB in 14 (17.5%), Stage II in 2 (2.5%) and Stage IIIC1 in 1 (1.25%) patient. Conclusion: Laparoscopic staging with SLNB using ICG is a practicable approach for uterine limited disease on preoperative evaluation. It extends the benefits of minimally invasive surgery to these patients, while overcoming the limitations of prohibitive cost or availability of expensive robotic equipment.

The Characteristics and Follow-Up of SARS-CoV-2 Infection in Pediatric Oncology Patients.

Introduction Clinical data about the first and second most prominent waves of SARS-CoV-2 among pediatric cancer patients were inconsistent. This study aims to retrospectively report the clinical characteristics and outcomes of SARS-CoV-2 infection in pediatric oncology patients. Methods This is an observational, retrospective study conducted in a tertiary care oncology center from March 2020 to May 2022. We reviewed the prevalence, severity of symptoms, and duration of positivity in relation to blood count laboratory data and mortality with a follow-up of 30 days post-infection for SARS-CoV-2. Results A total of 396 PCR tests were performed on 342 pediatric cancer patients. The overall rate of SARS-CoV-2 positivity was 43.1% (2.7% in the first wave and 95.4% in the second wave). Among 342 screened pediatric cancer patients, 72 patients had confirmed SARS-CoV-2 positivity in 92 different episodes. Nearly 59% had a mild or moderate infection, with fever and cough as the predominant presentations. The mean duration of positivity was 18.4±7.76 days. Comparing the laboratory values before and after acquiring the COVID-19 infection, only monocytes, hemoglobin, hematocrit, and platelets were statistically significantly affected, with P-values of 0.002, 0.03, 0.02, and 0.01, respectively. More than 18% of patients had grade 3 to 4 neutropenia (absolute neutrophil count=0.39±0.35) before COVID-19 infection and remained neutropenic throughout the disease, regardless of symptom severity. The mean recovery time was 13.67±8 days, which resulted in a delay in cancer treatment delivery of up to four weeks in 42.2% of patients. Conclusion Our data demonstrated that pediatric cancer patients with SARS-CoV-2 infection have a mild to moderate course of COVID-19 disease, with the majority being symptomatic, yet a great portion of our study population experienced treatment interruptions reaching up to four weeks caused by COVID-19.

ABO blood group discrepancies in blood donor and patient samples at a tertiary care oncology centre: analysis and serological resolution

IntroductionIn serological testing, determination of ABO grouping requires both antigen typing for A and B antigens and screening of serum or plasma for A and B antibodies. Lack of corroboration between the results of the cell and serum groupings identifies a discrepancy. Analysis of ABO blood group discrepancies was performed to determine the incidence of these discrepancies among healthy blood donors and oncology patients. Materials and methodsABO discrepancies found during testing of blood samples from blood donors and patients in an oncology centre in the period from January 2015 to December 2018 were analysed. ABO blood grouping was performed using the column agglutination test. Detailed serological workups were carried out to resolve discrepancies. ResultsDuring the study period, a comprehensive analysis was conducted on a large dataset comprising 76,604 blood donor samples and 134,964 patient samples. Of these samples, 117 ABO discrepancies were identified with 13 occurring in blood donor samples and 104 in patient samples. The results demonstrated discrepancies caused by weakened/missing antibodies, weakened/missing antigens, panagglutination and miscellaneous factors in the blood donor samples, with percentages of 0%, 38%, 8%, and 31%, respectively. In patient samples, the percentages were 24%, 27%, 26%, and 15%, respectively. ConclusionWeakened/missing antigen discrepancies were the prevalent type in both blood donor and patient samples. For accurate blood group reporting and management of transfusion needs of patients, a complete serological workup is vital to resolve any blood group discrepancies.

Cross-sectional imaging review of common to uncommon lung cancer mimickers in a tertiary care oncology center.

Lung cancer is the most diagnosed cancer worldwide. Many non-malignant pulmonary lesions, such as tuberculosis, fungal infection, organizing pneumonia, inflammatory myofibroblastic tumor, and IgG4 disease, can mimic lung cancer due to their overlapping morphological appearance on imaging. These benign entities with minor differentiating imaging clues may go unnoticed in a high-volume cancer institution, leading to over-investigation that may result in repeated biopsies, pointless wedge resections, and related morbidities. However, with a thorough medical history, laboratory diagnostic work-up, and careful analysis of imaging findings, one can occasionally restrict the range of possible diagnoses or arrive at a definitive conclusion. When imaging features overlap, image-guided lung sampling is crucial since histopathological analysis is the gold standard.

Can EPIC Be a Low-Cost Alternative to HIPEC in Advanced Epithelial Ovarian Cancer in Resource-Constraint Settings? Experience from Tertiary Care Oncology Center.

Management of advanced ovarian cancer underwent a paradigm shift with advent of cytoreductive surgery and intraperitoneal chemotherapy. Hyperthermic intraperitoneal chemotherapy requires complex machinery and costly disposables, and increased operative time. Early postoperative intraperitoneal chemotherapy is a relatively less resource-intensive alternative way of intraperitoneal drug delivery. We started our HIPEC programme in 2013. In select cases, we offer EPIC. This study is an audit of outcomes to look into the feasibility of EPIC as alternative to HIPEC. We performed analysis of prospectively maintained database in the Department of Surgical oncology from January 2019 to June 2022. We had 15 patients who underwent CRS + EPIC and 84 CRS+ HIPEC. We did a propensity-matched analysis for demographics, baseline data and PCI and compared 15 CRS + EPIC with 15 CRS + HIPEC patients. We compared the perioperative outcomes-morbidity, mortality, length of ICU and hospital stay. Procedure time was significantly higher in the HIPEC compared to EPIC as HIPEC is an intraoperative procedure. Patients were admitted to intensive care unit (ICU) after surgery for a longer mean duration in HIPEC arm (1.4 + 0.7 days) compared to EPIC arm (1.2 + 0.41 days). Patients in HIPEC arm had a significantly shorter hospital stay (mean 7.93 vs. 9.93 days. Four patients in EPIC arm had Clavien-Dindo grade 3 and 4 morbidity compared to 1 patient in HIPEC arm. Hematological toxicity was more common in EPIC group. CRS with EPIC can be explored as an alternative to HIPEC in centres lacking facilities and expertise for HIPEC.

Short and long outcomes of endoscopic bilateral metal stent placement for malignant hilar biliary obstruction: Tertiary care oncology centre experience.

Placement of biliary self-expanding metal stents (SEMS) has been effective for palliation of unresectable hilar malignant biliary obstruction. Optimal drainage in hilar obstruction may require placement of multiple stents. Data on multiple SEMS placement in hilar obstruction from India is sparse. Retrospective review of patients with unresectable malignant hilar obstruction who underwent endoscopic bilateral SEMS insertion from 2017 to 2021 was done. Demographic details, technical success and functional success (decrease in the bilirubin value below 3mg/dL at fourweeks), immediate complications with 30-days mortality, requirement of re-intervention, stent patency and overall survival were studied. Forty-three patients were included (mean age 54.9years, 51.2% females). Thirty-six patients (83.7%) had carcinoma gallbladder as primary malignancy. Twenty-six patients (60.5%) were metastatic at presentation. Cholangitis was seen in 4/43 (9.3%). On cholangiogram, 26 (60.4%) had Bismuth type II block, 12 (27.8%) had type IIIA/B, 5 (11.6%) had type IV block. Technical success was achieved in 41/43 (95.3%) patients (38, side-by-side SEMS placement; 3, SEMS-within-SEMS in Y fashion). Functional success was achieved in 39 patients (95.1%). No moderate-severe complications were reported. Median post-procedure hospitalization was five days. Median stent patency was 137days (interquartile range [IQR] 80-214days). Re-intervention was required in four patients (9.3%) after mean 295.7days. Median overall survival was 153days (IQR 108-234days). Endoscopic bilateral SEMS in complex malignant hilar obstruction has good outcomes in the form of technical success, functional success and stent patency. Survival is dismal despite optimal biliary drainage.

Experience with Generic Pegylated L-asparaginase in Children with Acute Lymphoblastic Leukemia from a Tertiary Care Oncology Center in South India.

Dhaarani JayaramanBackground Acute lymphoblastic leukemia (ALL) is a common type of leukemia in children. The innovator pegylated L-asparaginase has several advantages over native L-asparaginase; however, its use in India is limited due to availability and cost. Therefore, a generic pegylated L-asparaginase can be considered as an alternative to the innovator molecule. Methods A retrospective study was conducted to assess the outcome (minimal residual disease [MRD]) and toxicity of a generic pegylated L-asparaginase (Hamsyl) at the end of induction therapy. Results Eighty-eight (80.7%) and 21 (19.3%) patients had received generic pegylated L-asparaginase and conventional asparaginase, respectively, as a part of their treatment protocol. Nearly 82% of patients had B-type ALL. Eight-one percent of children had a white blood cell count of fewer than 50,000/mm 3 . At the end of induction, 80.7% (88) of children were minimal residual disease (MRD)-negative, and at the end of augmented consolidation therapy, 20.2% were MRD-negative. Ten percent of patients exhibited allergic reactions. Two children had pancreatitis, and one child had central venous thrombosis. Conclusion The generic pegylated L-asparaginase (Hamsyl) was effective and safe for use in pediatric ALL.

Gestational Trophoblastic Neoplasia—A Retrospective Analysis of Patients Treated at a Tertiary Care Oncology Center in North India

Objectives The aim of this study was to do a retrospective analysis of patients of gestational trophoblastic neoplasia (GTN) treated at our center concerning their clinical features and treatment outcomes. Materials and Methods Patients diagnosed and treated from May 2018 to December 2021 were included. All relevant information pertaining to eligible patients was retrieved from the electronic medical records. Patients were risk-stratified based on the World Health Organization (WHO) risk scoring system with a score of seven and above being classified into the high-risk category. Patients were monitored for response by measuring β-human chorionic gonadotrophin (β-HCG) levels before each consecutive cycle. Statistical Analysis Appropriate statistical analysis was performed using SPSS version 26. Results Records of 39 eligible patients were analyzed for clinical features out of which 38 were eligible for response assessment. The median age of presentation was 28 years with the majority of patients (79.4%) diagnosed based on β-HCG levels and clinical history alone. The most common symptom was bleeding per vagina (64%), while the majority of antecedent pregnancies were abortions (59%).Of the 14 low-risk category patients, 12 received single-agent methotrexate/actinomycin D, while 2 received etoposide, methotrexate actinomycin D (EMACO) regimen. Overall response rates were 85.7% with the others responding to the second-line EMACO regimen. Five patients in this group had a WHO score of 5 or 6 and all of them responded to single-agent treatment. Among the 25 high-risk category patients, all received the EMACO regimen with high-dose methotrexate added to those with brain metastasis. The response rate was 87.5% with all the nonresponders having features of ultra-high risk of liver/brain metastasis and/or a WHO score of more than 12. While one nonresponder had expired despite treatment, the other two responded to the etoposide methotrexate and actinomycin D/ etoposide and cisplatin regimen. Conclusion Our results are in consonance with other reported studies. The subcategories of low-risk GTN with a WHO score of 5 and 6 and high-risk GTN with ultra-high-risk features deserve further research in the form of multicenter prospective studies.

Determination of the Rh/Kell phenotypes in donor as well as patients might be significant to provide phenotype-matched blood to cancer patients: A retrospective analysis from a tertiary care oncology center in North India.

Multiple reports are available from different parts of the globe indicating the incidences of alloimmunization and blood transfusion-related reactions, which emphasizes the need for phenotyping and providing antigen-matched safe blood. This study aims to determine the frequency of Rh and Kell antigens and phenotype for both donors and patients to propose the importance of providing Rh Kell phenotype cross-matched packed red blood cell (RBC) units to minimize the alloimmunization and transfusion reactions. Ten thousand blood donors and four thousand patients were investigated between October 2017 and July 2019. Each donor unit was tested for blood grouping, antibody screening, and Rh Kell antigen Phenotyping, and the blood unit was issued after the patient's blood grouping, antibody screening by 3 cell panels, and Rh Kell antigen phenotyping followed by cross-matching with an Rh Kell-matched phenotype RBC unit. Nine thousand four hundred and fifty-two donors were D positive (94.5%) while 548 tested D negative (5.5%). Overall Rh and K antigens frequencies in donors were: "e" (98%) >"D" (94.5%) >"C" (86.6%) > "c" (57.5%) >"E" (18.8%) >K (0.98%). Among patients, 3762 tested D positive (94.05%), and 238 tested D negative (5.95%). Overall Rh and K antigens frequencies in patients were: "e" (98.5%) >"D" (94.05%) >"C" (90.2%) >"c" (51%) >"E" (18.2%) >K (1.8%). Our study has given us more clarity on the prevalence of major Rh and K antigens in our donor as well as patient populations, highlighting the similarities as well as differences. This variance holds a great significance, since such donor units when transfused into patients may lead to alloimmunization and adverse transfusion reactions. Hence, the determination of Rh and Kell phenotypes and providing phenotype-matched blood will help prevent such events.

Evaluation of Appropriateness of Red Blood Cell Transfusions

Background and Objectives: Red blood cells (RBC) transfusion is an important medical therapy in modern medicine. Blood is a scarce resource used in large numbers; therefore, it is very essential for its components to be used appropriately and judiciously. It is necessary to monitor, assess, and evaluate the existing trends and appropriateness of blood utilization. The establishment of criteria for blood transfusion and strict adherence to such criteria may be necessary to improve blood usage. The objective of this study was to understand the utilization pattern of RBC transfusions based on indications and to evaluate the appropriateness of RBC transfusion at a tertiary care oncology center. Methods: This was a prospective observational study conducted over a period of 4 months. A total of 4413 RBC transfusion events in 2012 adult oncology patients were analyzed for appropriateness as per institutional guidelines. Data were obtained from the blood requisitions, issue records of the Department of Transfusion Medicine and from the Electronic Medical Records of the patients. Results: Total of 83% of transfusion events were found to be appropriate with Anemia being the most common indication for RBC transfusion in medical and surgical oncology units. Appropriateness was significant (P < 0.05) in medical oncology as compared to surgical oncology units. Appropriateness was highest and statistically significant (P < 0.05) in operation theatres while inappropriateness was more and significant in the daycare facility (P < 0.05). Conclusion: Total 83% of RBC transfusions were found to be appropriate indicating that clinical practices of RBC transfusions in the hospital were rational with adherence to institutional guidelines.
