Background: Triple-negative breast cancer (TNBC) includes approximately 20% of all breast cancer and is characterized by its aggressive nature, high recurrence rates, and visceral metastasis. Pathological complete response (pCR) is an established surrogate endpoint for survival. The window of opportunity studies provide valuable information on the disease biology prior to definitive treatment. Objectives: To study the association of dynamic change in pathological, imagining, and genomic biomarkers that can prognosticate pCR. The study aims to develop a composite prognostic score. Design: Clinical, interventional, and prognostic biomarker study using the novel window of opportunity design. Methods: The study aims to enroll 80 treatment-naïve, pathologically confirmed TNBC patients, administering a single dose of paclitaxel and carboplatin during the window period before neoadjuvant chemotherapy (NACT). Tumor tissue will be obtained through a tru-cut biopsy, and positron emission tomography and computed tomography scans will be performed for each patient at two time points aiming to evaluate biomarker alterations. This will be followed by the administration of standard dose-dense NACT containing anthracyclines and taxanes, with the study culminating in surgery to assess pCR. Results: The study would develop a composite prognostic risk score derived from the dynamic change in the Ki-67, tumor-infiltrating lymphocytes, Standardized Uptake Value (SUV max), Standardized Uptake Value for lean body mass (SUL max), and gene expression level pre- and post-intervention during the window period prior to the start of definitive treatment. This outcome will aid in categorizing the disease biology into risk categories. Trial registration: The current study is approved by the Institutional Ethics Committee [Ethics: Protocol. no. JIP/IEC/2020/019]. This study was registered with ClinicalTrials.gov [CTRI Registration: CTRI/2022/06/043109]. Conclusion: The validated biomarker score will help to personalize NACT protocols in patients in TNBC planned for definitive treatment.

Abstract Bortezomib, lenalidomide, and dexamethasone induction chemotherapy (VRd), followed by autologous stem cell transplantation (ASCT), are the standard of care for patients with newly diagnosed multiple myeloma (NDMM). Pomalidomide is currently approved for relapsed-refractory multiple myeloma. This single-arm, open-label, phase 2 study was the prospective evaluation of the efficacy and safety of bortezomib, pomalidomide, and dexamethasone (VPd) induction for NDMM. We used Fleming’s two-stage design for sample size calculation. We included transplant-eligible and ineligible patients aged 18–75 years in the study. The patients received four cycles of VPd induction followed by response assessment. Thirty-four patients were included in the study, of which 31 completed all four cycles of induction. The median age was 52 years (32–72). Thirty (91%) patients had multiple myeloma, and three had multiple plasmacytomas with less than 10% bone marrow involvement. Nine (27%) had ISS-I, 9 (27%) had ISS-II, and 15 (46%) had ISS-III myeloma. Three patients had high-risk cytogenetic abnormalities. After four cycles of VPd induction, ten patients (32%) achieved stringent CR, nine had CR (29%), eight (26%) had VGPR, and 4 (13%) had PR. Fifteen (48%) had a complete metabolic response (CMR) on PET-CT. Two patients developed SAEs. Anemia was the most common hematological toxicity. Peripheral neuropathy and constipation were the most common non-hematological toxicities. Patients with ≥VGPR had significantly better 12-month PFS than those with PR. Patients with ≥VGPR and CMR on PET-CT had significantly better 12-month OS. Our study showed VPd induction is safe and efficacious in NDMM. Further Phase 3 studies are necessary to establish the superiority and survival benefits.

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Abstract The benefit of three-drug induction chemotherapy over a two-drug induction has not been evaluated in pediatric acute myeloid leukemia (AML). We, therefore, conducted a randomized controlled trial to ascertain the benefit of a three-drug induction regimen. Patients aged 1–18 years with newly diagnosed AML were randomized to two cycles of induction chemotherapy with daunorubicin and ara-C (DA) or two cycles of ara-C, daunorubicin, and etoposide (ADE). After induction, patients in both arms received consolidation with two cycles of high-dose ara-C. The study’s primary objective was to compare the event-free survival (EFS) between the two arms. The secondary objectives included comparing the composite complete remission (cCR) rates, overall survival (OS), and toxicities. The study randomized 149 patients, 77 in the DA and 72 in the ADE arm. The median age was 8.7 years, and 92 (62%) patients were males. The median follow-up was 50.9 months. The cCR rate in the DA and ADE arm were 82% and 79% (p = 0.68) after the second induction. There were 13 (17%) induction deaths in the DA arm and 12 (17%) in the ADE arm (p = 0.97). The 5-year EFS in the DA and ADE arm was 34.4% and 34.5%, respectively (p = 0.66). The 5-year OS in the DA and ADE arms was 41.4% and 42.09%, respectively (p = 0.74). There were no significant differences in toxicities between the regimens. There was no statistically significant difference in EFS, OS, CR, or toxicity between ADE and DA regimens in pediatric AML. The trial was registered with the Clinical Trial Registry of India (Reference number: CTRI/2014/11/005202).

Glioma is the most devastating high-grade tumor of the central nervous system, with dismal prognosis. Existing treatment modality does not provide substantial benefit to patients and demands novel strategies. One of the first-line treatments for glioma, temozolomide, provides marginal benefit to glioma patients. Repurposing of existing non-cancer drugs to treat oncology patients is gaining momentum in recent years. In this study, we investigated the therapeutic benefits of combining three repurposed drugs, namely, metformin (anti-diabetic) and epigallocatechin gallate (green tea-derived antioxidant) together with temozolomide in a glioma-induced xenograft rat model. Our triple-drug combination therapy significantly inhibited tumor growth in vivo and increased the survival rate (50%) of rats when compared with individual or dual treatments. Molecular and cellular analyses revealed that our triple-drug cocktail treatment inhibited glioma tumor growth in rat model through ROS-mediated inactivation of PI3K/AKT/mTOR pathway, arrest of the cell cycle at G1 phase and induction of molecular mechanisms of caspases-dependent apoptosis.In addition, the docking analysis and quantum mechanics studies performed here hypothesize that the effect of triple-drug combination could have been attributed by their difference in molecular interactions, that maybe due to varying electrostatic potential. Thus, repurposing metformin and epigallocatechin gallate and concurrent administration with temozolomide would serve as a prospective therapy in glioma patients.

BACKGROUND: Plerixafor is used for patients at risk of Stem cell mobilization failure based on clinical factors or low peripheral blood CD34 count. It is also added upfront to any mobilization irrespective of risk factor, but the cost-effectiveness of the approach is an issue. Data on plerixafor in different settings of autologous hematopoietic stem cell (HSC) collection from India are scant. We are hereby reporting the experience of failure/success of mobilization rate and few important significant variables (CD34+ dosage, failed collection) between plerixafor and granulocyte colony-stimulating factor alone groups among autologous hematopoietic stem cell transplantation (aHSCT) at our institute. METHODS: This was a record-based single-center study on patients who underwent aHSCT from January 2013 to June 2019 at a tertiary care hospital. Descriptive statistics were used for baseline characteristics, transplant-related factors, and peritransplant outcomes. All statistical analyses were performed at the 5% significance level. RESULTS: During the study duration, a total of 96 patients had undergone autologous hematopoietic stem cell collection (aHSCC), all by peripheral blood stem cell harvest, requiring 131 apheretic collections. Of the total 131 collections in 96 patients, plerixafor was used in 63 apheresis collections (48% of total pheresis) in 40 patients. Among the 40 patients who were administered plerixafor to augment the collection, 34 patients had upfront use of plerixafor. We did not observe any significant adverse event related to plerixafor use. CONCLUSION: A rational utilization of plerixafor can facilitate the process and logistics of aHSCC outcome.

Lung cancer is one of the most common cancers and an important cause of cancer-related mortality. Recent advances in targeted therapy and immunotherapy have improved outcomes, but these have limited penetration in resource-constrained situations. We report the real-world experience in treating patients with lung cancer in India. A retrospective analysis of baseline characters, treatment and outcomes of patients with lung cancer seen between January 2015 to December 2018 (n = 302) at our center was carried out. Survival data were censored on July 31, 2019. A total of 302 patients (median age: 57 years [range, 23–84 years]; males [n = 203; 67.2%]) were registered. Adenocarcinoma was the most common histology (n = 225, 75%). The testing rate of epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) mutation analysis in stage IV adenocarcinoma (n = 191) was 67% and 63%, respectively. Systemic therapy (chemotherapy/gefitinib) was started after a median of 62 days (range, 1–748) from presentation and 38 days (range, 1–219 days) from diagnosis. The median progression-free survival (PFS) and overall survival (OS) were 4.3 months (95% CI, 3.2–5.4) and 9.0 months (95% CI, 7.6–10.5), respectively in the 141 patient without targetable mutations who started palliative chemotherapy. Of the 58 patients who tested positive for EGFR mutation, 41 (71%) started an EGFR tyrosine kinase inhibitor (TKI), and the median PFS and OS in these patients were 8.5 months (95% CI, 5.6–11.4) and 18.4 months (95% CI, 12.2–24.6), respectively. Only 1 out of 10 patients with stage IV ALK-positive adenocarcinoma was started on ALK inhibitor. On multivariate analysis of OS for patients who started on palliative chemotherapy, response to first-line treatment, long distance from the center, use of second line therapy, and a delay of > 40 days from diagnosis to treatment predicted improved survival. Despite providing free diagnostic and treatment services, there was considerable delay in therapy initiation, and a significant proportion of treatment noninitiation and abandonment. Measures should be taken to understand and address the causes of these issues to realize the benefits of newer therapies The apparent paradox of improved survival in those with long delay in initiation of treatment could be explained based on a less aggressive disease biology.

Context Clostridioides difficile infection (CDI) is one of the most common infectious causes of hospital-acquired diarrhea. The actual burden of the disease is underestimated in India due to inadequate diagnostic methods and limited studies conducted. Aims The aim of this study was to determine the burden and risk factors of CDI among patients with hospital-acquired diarrhea. Methods and Materials Stool specimen of patients (age > 1 year) with hospital-acquired diarrhea were screened for glutamate dehydrogenase antigen and toxin using an enzyme immunoassay. If both antigen and toxin were present, it was reported as positive for toxigenic CDI. Samples positive for antigen and negative for toxin were further tested with Cepheid GeneXpert assay for detecting the toxin producing gene. Results Of 75 patients (mean age 36.07 ± 20.79, 64% males), 14 (18.67%) patients were positive for toxigenic Clostridioides difficile (C. difficile) and 3 (4%) patients were nontoxigenic C. difficile. Addition of GeneXpert to the testing algorithm increased the yield of toxin detection in 5/14 patients who were negative by toxin assay. On analysis of risk factors, prolonged hospital stay was found to have significant association (p-value = 0.022). Patients with factors like intensive care unit stay, presence of diabetes mellitus as a comorbidity, and exposure to antibiotics like carbapenems and glycopeptides have been found to have a higher prevalence of CDI. Conclusions The prevalence of CDI in our population was 18.67% and the major risk factor associated was prolonged hospital stay. The addition of GeneXpert for the detection of toxin gene increased the yield from 12 to 18.68%.

Background Adherence to oral anticancer medication is important in cancer chemotherapy, with the advent of many oral anticancer regimens to ensure adequate cytologic response. Literature on adherence to oral anticancer therapy in India is very less. Materials and Methods This is a cross sectional analytical study consisting of all fit patients > 18 years of age taking oral anticancer therapy, with or without intravenous (IV) chemotherapy. Adherence was determined using Morisky–Green–Levine (MGL) scale, and factors affecting adherence details about cancer and treatment were obtained. All fit patients were recruited. Information was obtained using Tamil questionnaire and pro forma. Observation Of 152 patients, only 111 patients were found to be adherent to treatment. The mean age of the study population was 49.03 ± 13.48 years. Only 12.5% of patients were aware of the diagnosis, treatment, and outcome. The study population consisted mainly of patients with chronic myeloid leukemia, colorectal carcinoma, breast carcinoma, and stomach carcinoma, which amounted for 78.3% of the study population. Bivariate analysis concluded that duration of treatment, adverse drug reaction (ADR), duration of oral anticancer drug intake in a month, coadministration with IV anticancer drugs, and frequency of drug intake (anticancer drug) were significant factors affecting drug adherence. Multivariate analysis of the above variables was insignificant, but ADR tended toward significance. Conclusion Drug adherence plays a major role in treatment outcome in cancer patients. ADR was independently associated with decreased drug adherence. Key interventions which should include counseling and behavioral modifications will reduce nonadherence.

Introduction: Cancer is a global problem and it is a leading cause of death worldwide. Nausea, vomiting and retching are one of the common side effects that are seen among the majority of the patients undergoing chemotherapy. Foot massage is a complementary therapy that reduces Chemotherapy-Induced Nausea and Vomiting (CINV) and improves the quality of life among cancer patients undergoing chemotherapy. This study aim to measure the effectiveness of foot massage in reduction of nausea, vomiting & retching on patients undergoing chemotherapy treatment. Methods: A randomized clinical trial study was used to assess the effect of foot massage on patients with Chemotherapy-induced nausea and vomiting among patients undergoing highly emetogenic chemotherapy. Simple random sampling by the lottery method was used to select newly diagnosed cancer patients who underwent highly emetogenic chemotherapy (N= 82). Rhodes index of nausea, vomiting and retching questionnaire were used for data collection . SPSS 19, two-sample t-test, paired t-test and chi-square test were used for data analysis. Result: Nausea, vomiting, and retching were significantly reduced in the experimental group compared to the control group after the intervention. There was a significant difference between pre-intervention and post-intervention scores within the group. Conclusion: The findings of the study revealed that the foot massage therapy is effective in reducing chemotherapy-induced nausea and vomiting among patients undergone highly emetogenic chemotherapy. The study helped to conclude that foot massage can be considered effective intervention in chemotherapy patients.

CD34 and CD79a are markers of hematopoietic stem cell and B-lymphoid cells, respectively. The abnormal expression of these markers in megakaryocytes has been noticed in cases of myelodysplastic syndrome, inherited platelet disorders, and reactive erythrocytosis. As a routine practice, while studying post-induction chemotherapy marrows in acute leukemia, immunomarkers, positive in the initial diagnostic workup, were performed to look for the residual blasts. Interestingly, we noticed CD34 immunopositive megakaryocytes in four such cases. CD79a positive megakaryocytes were also seen in five other cases of post-induction acute lymphoblastic leukemia. All these megakaryocytes, which were regenerating and in clusters, showed both topographic and cytological features of dysmegakaryopoiesis. CD 34 and CD79a, which are often used to monitor residual disease in the post-chemotherapy bone marrow, show aberrant positivity in the megakaryocytes. This novel finding of regenerating megakaryocytes may be used as a feature of dysmegakaryopoiesis in megakaryocytes.

Medicine ,Science - Abstract
Letrozole, an aromatase inhibitor (AI), is the first-line adjuvant drug for treating hormone receptor-positive (HR+) breast cancer in postmenopausal women. However, harmful adverse events (AEs) and significant differences in drug response among individuals remain a significant problem in clinical application. Current evidence suggests that the observed individual variation in the treatment outcomes of AI is conferred by genetic variants. Hence, in this study, we examined the association of TCL1A gene polymorphisms with letrozole-induced AEs. The study subjects were postmenopausal HR+ breast cancer patients who were receiving adjuvant letrozole. Genomic DNA was isolated by a routine standard phenol-chloroform method. In total, 198 South Indian patients were genotyped for four single nucleotide polymorphisms (SNPs) in the TCL1A gene loci by the TaqMan allelic discrimination assay using the RT-PCR system. We used the odds ratio and 95% confidence interval to assess the genetic association. Musculoskeletal (MS) AEs and vasomotor symptoms (VMSs) are the most common side effects observed in the study cohort. Among 198 patients, 81 experienced musculoskeletal toxicity, reporting MS-AEs, 57 had VMSs, and 33 of them had both. The most frequently identified polymorphic variants in the patient series were rs11849538 (G), with an allele frequency of about 27.3%, followed by rs7158782-G (27.3%), rs7159713-G (25.8%), and rs2369049-G (22.5%). The genetic association analysis indicated no significant difference in the proportion of TCL1A gene variants between patients with and without AEs on either MS-AEs or VMSs. Though we observed high LD in all patient groups, the inferred haplotypes displayed a non-significant association with letrozole-induced specific AEs. However, the SNP functionality analysis by RegulomeDB provided a 2b rank score for rs7158782, suggesting a potential biological function. Our findings suggest that TCL1A gene polymorphisms may not play any role in the prediction of letrozole-induced AEs in South Indian HR+ breast cancer patients.

Background: Acute lymphoblastic leukemia (ALL) patients are susceptible to hepatitis B infection due to profound immunosuppression and repeated transfusions. However, the comparative effectiveness of hepatitis B vaccination in different phases of chemotherapy has not been studied. Aim: In this comparative interventional study (CTRI/2017/08/009402), vaccination in the induction phase (IP) was compared to that in the maintenance phase (MP). Materials and Methods: The participating ALL patients in both groups (29 per group) were vaccinated with double the dose of hepatitis B vaccine at 0, 1, and 2 months. The proportion of patients with seroprotective anti-hepatitis B surface titers (>10 IU/ml) was compared between the two groups after each dose. Results: The seroprotection rates between both the phases were similar following the first (relative risk [RR] = 4, confidence interval [CI]: 0.47–33.65) and third (RR = 1.4, CI: 0.73-2.84) doses of vaccination, whereas following the second dose of vaccination, the seroprotection rate in IP was significantly higher than that of MP (RR = 1.9, CI: 1.07–3.35). Conclusion: This study concluded that a 0, 1, and 2 schedule of hepatitis B vaccination has similar efficacy in both the IP and the MP of chemotherapy in ALL patients. As the IP has a higher trend of seroprotection rates compared to MP, vaccination in IP followed by revaccination postchemotherapy may be preferred in countries with a high prevalence of hepatitis B infection.

Background: With the introduction of newer anti-cancer agents, the adverse effects have become more rampant which call for concern in the treatment of patients with cancer. Hence, the assessment and management of dermatological adverse effects of anti-cancer therapy have become a significant part of the care of patients with cancer and require proper and close collaboration between the dermatologists and the oncologists. Aims: To assess the frequency and pattern of mucocutaneous adverse reactions to cancer chemotherapy and chemoradiation and grade them according to their severity and to identify hematological and biochemical changes related to cancer chemotherapy-induced mucocutaneous adverse reactions. Materials and Methods: This was a descriptive study done among 226 patients in an Indian tertiary care hospital, who presented with mucocutaneous adverse reactions to either chemotherapy alone or combination of chemotherapy and radiation to dermatology, medical oncology and radiotherapy outpatient departments. Detailed history and examination were undertaken. Visual analog score (VAS) was employed to quantify pain and pruritus. Correlation of various biochemical and hematological parameters with chemotherapy-induced adverse reactions was attempted and grading of adverse reactions was done based on the severity scale of Common Terminology Criteria for Adverse Events (CTCAE). Results: The common cutaneous adverse reactions observed in our study were nail changes (194 patients; 85.84%), followed by skin changes (191; 84.51%), hair changes (159, 70.35%), mucosal changes (34, 15.04%), and other miscellaneous manifestations. Grade 1 manifestations comprised of 49.91% of total manifestations followed by Grade 2 (45.45%) and Grade 3 (5.64%). In addition to bleomycin, other chemotherapeutic agents also had been shown to produce flagellate dermatitis in our study. Conclusion: Nail changes, skin changes, hair changes and mucosal changes occurred frequently as a significant side effect of chemotherapy, which a physician should be aware of, while selecting a chemotherapeutic drug.

With an increase in the use of high dose chemotherapeutic regimens, higher cure rates and longer survival periods of cancer patients, the incidence of secondary malignancies are increasing. Therapy related Myeloid Neoplasm (t-MN) is a second malignancy after chemotherapy/radiotherapy given for a prior malignancy. Of the various t-MN Acute Promyelocytic Leukaemia (APML) as a complication of chemo-radiotherapy is very rare. We report a rare case of therapy related APML in a breast cancer survivor.

Introduction: Nodal Peripheral T-Cell Lymphomas (NPTCL) are a rare and heterogeneous group of lymphomas seen to occur more often in Asian, including South Indian population. They have an overall poor prognosis. Aim: To document the varied spectrum of clinico-radiological, histopathological and follow-up parameters of NPTCL. Materials and Methods: This descriptive cohort study involved clinical, histopathological and haematological workup of NPTCL cases diagnosed from January 2008 to June 2013 in JIPMER, Puducherry, India. The cases were diagnosed as per World Health Organisation (WHO) 2008 classification. Results: NPTCL accounted for 25% of all Non-Hodgkin Lymphomas (80 cases). Peripheral T-cell Lymphoma-not otherwise specified (PTCL-NOS), Anaplastic Large Cell Lymphoma, ALK-positive (ALCL, ALK+), Anaplastic large cell lymphoma, ALK-negative (ALCL, ALK-) and Angioimmunoblastic Lymphoma (AITL) contributed to 51%, 29%, 10% and 10% of the cases respectively. A majority of patients (68%) had generalised lymphadenopathy, 26% had hepatosplenomegaly and 38% had marrow infiltration. Histomorphology showed wide variation within and in between the subgroups. Overall, necrosis, fibrosis and high mitosis were more common in ALCL while increased vascularity was seen prominently in AITL. At least 70% of the cases in each entity had advanced stage of disease. Conclusion: There is a three-fold increase in incidence of NPTCL lymphomas in JIPMER compared to WHO (2008). Most patients presented with advanced stage and in sixth decade, except ALCL. There was wide histomorphological variability among these cases. Awareness of the entity and its histopathological heterogeneity would be worthwhile in arriving at a conclusive diagnosis.

Introduction Follicular lymphoma (FL) is an indolent chronic lymphoproliferative disorder of B-cells with variable clinical behaviour. It is the second most common subtype of Non-Hodgkin lymphoma in western countries but reported to have a lower incidence in Asia. Materials and methods Cases of FL diagnosed in the Department of Pathology of our Institute from January 2009 to June 2015 were included in the study. The clinicopathological parameters including staging, histological details and immunohistochemical markers CD20, CD10, Bcl2 and Ki67 were recorded in all the cases. Results Of the 497 cases of Non-Hodgkin Lymphoma reported during the study period, 36 (7.2%) cases were follicular lymphoma. The mean age was 50 years with male to female ratio of 3.2:1. Grade 1/ 2 was seen in 70% cases. 22 % cases had low grade with high proliferation index (Ki67 > 40%). Granulomatous response was seen in two cases. Diffuse large cell lymphoma component was present in four cases. Bone marrow involvement and peripheral blood spill was seen in 12 (37.5%) and six cases (18.8%) respectively. 72% cases were in stage 3 or 4. Conclusion Incidence of FL was lower in our study than other Indian studies. FL presented in the elderly, with male predominance and disseminated stage. Features of low grade with high proliferation index, granulomatous response, leukemic involvement and transformation to high grade lymphoma are highlighted in the study.

Follicular Lymphoma (FL) is the second most common B-Non Hodgkin Lymphoma after diffuse large B cell lymphoma (DLBCL). Low grade FL is known for its indolent behavior; however, one subset of FL behave aggressively and may require intensive therapy. One of the diagnostic issues in FL is to identify this subgroup of cases. Proliferation index can have prognostic importance in this subset of cases. We discuss one case of low grade FL with a paradoxically high proliferative index. A 63 year male presented with generalized lymphadenopathy of one year duration, which was gradually increasing in size. On examination, patient had bilateral cervical, axillary and inguinal nodes. Biopsy of the left cervical lymph node was reported as FL - Grade 2, with high proliferative Index (60%). The patient was put on CHOP regimen targeted for high grade lymphomas, and had complete remission. High proliferative index in FL is a poor prognostic factor irrespective of the histologic grade. So, proliferative index should be assessed in all cases of FL as an adjunct to histologic grading.

Background: Palmar plantar erythrodysesthesia (PPE) is a dose limiting toxicity of anticancer agents. In some cases it may mandate for discontinuation of anticancer agents. Evaluation of data of PPE among reported adverse drug reactions (ADRs) from the Department of Medical Oncology could quantify the burden. Aim: To evaluate and analyse the PPE among reported ADRs from medical Oncology. Materials and Methods: The data of all cases of reported PPE were collected during January 2012 to September 2013 and were analysed with WHO causality assessment scale. The severity was clinically graded. The follow-up data regarding outcome of ADRs were also noted. Results: During the study period of 21 months a total of 1418 ADRs have been reported from 1076 patients. Among them PPE was reported from 31 cases (2.9%). Majority (32.2%) of these patients were on chemotherapy for breast cancer. Patient’s age ranged from 17 to 68 y and the median age was 50 y. There were 18 female (58%) and 13 male patients (42%). Capecitabine was the leading drug involved in PPE, reported with 20 cases (64.5%), and followed by docetaxel with 5 cases (16.1%). Majority (67.7%) of the reactions was categorized as certain and 64.5% was grade II severity clinically. Conclusion: Our findings show that PPE accounts for 2.9% of total reported ADRs from Medical Oncology during 21 months. Majority of the reactions were classified as certain. Capecitabine is commonly implicated drug.

PURPOSE Anorexia occurs in 30%-80% of patients with advanced malignancies, which may be worsened with chemotherapy. This trial assessed the efficacy of olanzapine in stimulating appetite and improving weight gain in patients receiving chemotherapy. METHODS Adults (≥18 years) with untreated, locally advanced, or metastatic gastric, hepatopancreaticobiliary (HPB), and lung cancers were randomly assigned (double-blind) to receive olanzapine (2.5 mg once a day for 12 weeks) or placebo along with chemotherapy. Both groups received standard nutritional assessment and dietary advice. The primary outcomes were the proportion of patients with weight gain > 5% and the improvement in appetite (assessed by the visual analog scale [VAS] and the Functional Assessment of Chronic Illness Therapy system of Quality-of-Life questionnaires Anorexia Cachexia subscale [FAACT ACS]). Secondary end points were change in nutritional status, quality of life (QOL), and chemotherapy toxicity. RESULTS We enrolled 124 patients (olanzapine, 63 and placebo, 61) with a median age of 55 years (18-78 years), of whom 112 (olanzapine, 58 and placebo, 54) were analyzable. The majority (n = 99, 80%) had metastatic cancer (gastric [n = 68, 55%] > lung [n = 43, 35%] > HPB [n = 13, 10%]). The olanzapine arm had a greater proportion of patients with a weight gain of > 5% (35 of 58 [60%] v 5 of 54 [9%], P < .001) and improvement in appetite by VAS (25 of 58 [43%] v 7 of 54 [13%], P < .001) and by FAACT ACS (scores ≥37:13 of 58 [22%] v 2 of 54 [4%], P = .004). Patients on olanzapine had better QOL, nutritional status, and lesser chemotoxicity. Side effects attributable to olanzapine were minimal. CONCLUSION Low-dose, daily olanzapine is a simple, inexpensive, well-tolerated intervention that significantly improves appetite and weight gain in newly diagnosed patients on chemotherapy.

Objectives: Oncology caregivers often endure a significant amount of psychosocial stress while going through the experience of caregiving for their dependents. Exposure to chronic stress disrupts the cardiac autonomic balance and increases the risk of cardiovascular events. There is a paucity of research on the association between caregiving strain and cardiac autonomic status of primary oncology caregivers. This study aimed to assess the cardiac autonomic balance and its association with the levels of perceived strain and quality of life (QOL) of primary oncology caregivers. Materials and Methods: Forty-six individuals (30 males and 16 females) who have been primary caregivers of patients under the treatment for cancer at the Regional Cancer Centre over the past 3 months–1 year were recruited in this cross-sectional study. Cardiac autonomic status was assessed by heart rate variability (HRV) technique. The level of strain perceived and QOL of the study participants were assessed using the Modified Caregiver Strain Index (MCSI) and Caregiver QOL-Cancer (CQOL-C) questionnaires, respectively. Comparison of study parameters based on MCSI scores (low strain vs. moderate-high strain) was done using the Independent Student’s t-test. Spearman rank correlation coefficient test was performed to assess the correlation between sympathovagal balance (Low frequency [LF]/high frequency [HF]) and other study parameters. Multiple linear regression analysis was performed to predict the LF/HF ratio with independent variables MCSI score and CQOL-C score. P < 0.05 was considered statistically significant. Results: Significantly high blood pressure, LF power, LF nu (LF normalised units) and LF/HF ratio were observed among caregivers with moderate-to-high caregiving strain as compared to those with low strain levels, while significantly low HF nu (HF normalised units) and CQOL-C scores were noted among the moderate-to-high caregiving strain subgroup as compared to the low caregiving strain subgroup. LF/HF ratio revealed a significant positive correlation with the level of caregiving strain (r = 0.563, P < 0.001) and a significant negative correlation with the QOL (r = −0.489, P = 0.001) of caregivers. However, on regression analysis, the level of caregiving strain was found to be a significant predictor of autonomic dysfunction unlike the caregivers’ QOL. Conclusion: Increased caregiving strain is associated with cardiac autonomic imbalance in primary oncology caregivers.

Introduction Caudal-type homeobox 2 (CDX2), a nuclear protein, is essential for the proliferation and development of intestinal epithelial cells and is frequently downregulated during tumorigenesis. CDX2 inhibits cell growth as well as stimulates differentiation by activating intestinal specific genes, thus lack of CDX2 favors tumor growth and aggressiveness. Objectives We aimed to evaluate the pattern of CDX2 expression in all stages of colorectal cancer (CRC) and study its association with baseline characteristics and prognosis. Materials and Methods Study was conducted as an ambispective observational study, enrolling cases of CRC retrospectively from January 2014 to July 2016 (30 months), and prospectively during next 18-month period till January 2018. We performed CDX2 staining by immunohistochemistry on the available biopsy blocks of CRC patients during the study period. Total 286 patients were registered during the study period, of which only 110 biopsy blocks were available for staining. CDX2 scoring was done by a semiquantitative method on whole tissue section for the intensity and percentage of the cells showing positivity. Correlation of CDX2 expression was done with baseline clinical and histopathologic characteristics, and survival. Results Of 110 patients, 77 (70%) constituted colon cancer and 33 (30%) were rectal cancer. The median age was 54.2 years, 62 (56.4%) being male and 48 (43.6%) female with male-to-female ratio 1.3:1. In the study cohort, 33 (30%) patients had stage II disease, 30 (27.3%) stage III, and 47 (42.7%) were stage IV. Seventy-three (66.4%) were positive for CDX2 and 37 (33.4%) were negative. Loss of CDX2 expression was significantly associated with advanced stage, rectal site, poor grade of differentiation, and presence of lymphovascular invasion (LVSI). With median follow-up of 16 months, progression-free survival (PFS) at 2 years was 30% for CDX2 negative patients compared with 67% for CDX2 positive (p = 0.009), while overall survival (OS) at 2 years was 46% for CDX2 negative versus 77% for positive patients (p = 0.01). Conclusion Loss of CDX2 expression is associated with advanced stage, higher tumor grade, presence of LVSI, and worse PFS and OS and thereby functions as a poor prognostic factor in CRC.

Oncology ,Pediatrics, Perinatology and Child Health - Abstract
The blast phase (BP) is challenging to treat and leads to inferior survival in chronic myeloid leukemia (CML). Allogeneic hematopoietic stem cell transplant (AlloSCT) is the only curative option for CML-BP. We are sharing our experience of AlloSCT in seven patients with CML-BP who underwent transplants during the period from January 2017 to December 2019. Three patients each had myeloid-BP, lymphoid-BP, and one patient had mixed phenotypic BP. Donors were matched siblings in four, mismatched siblings in one, and haploidentical in two. All patients received peripheral blood stem cell grafts. The median CD34+ dose was 7.6 (range: 6.6–8.9) × 106 cells/kg. Neutrophil engraftment was observed at a median of 15 (10–20) days and platelet engraftment at 19 days (10–22). At a median follow-up of 24 months, the 2-year leukemia-free survival (LFS) and overall survival (OS) were 43% and 57%, respectively. Transplant-related, non-relapse mortality was observed in three patients. AlloSCT results in promising survival for carefully selected patients of CML-BP, especially with a matched sibling donor.

Double pneumonia with Pneumocystis jirovecii (PCP) and Mycobacterium tuberculosis (MTB) has been reported in patients with acquired immune deficiency syndrome. A similar immune-suppressed state exists in allogeneic transplant survivors treated for graft-versus-host disease (GVHD). The clinical features and imaging findings could be quite similar in both the etiologies. Reaching a timely diagnosis and initiation of appropriate therapy is essential to prevent complications. We report a patient who had concurrent PCP and MTB pneumonia while on treatment for chronic GVHD. We describe the diagnostic challenge, the treatment, and outcome of this patient. We intend to sensitize physicians to consider more than one etiology in this subset of patients.

- Abstract
Glioma is the most devastating high-grade tumor of the central nervous system, with dismal prognosis. Existing treatment modality does not provide substantial benefit to patients and demands novel strategies. One of the first-line treatments for glioma, temozolomide, provides marginal benefit to glioma patients. Repurposing of existing non-cancer drugs to treat oncology patients is gaining momentum in recent years. In this study, we investigated the therapeutic benefits of combining three repurposed drugs, namely, metformin (anti-diabetic) and epigallocatechin gallate (green tea-derived antioxidant) together with temozolomide in a glioma-induced xenograft rat model. Our triple-drug combination therapy significantly inhibited tumor growthin vivoand increased the survival rate (50%) of rats when compared with individual or dual treatments. Molecular and cellular analyses revealed that our triple-drug cocktail treatment inhibited glioma tumor growth in rat model through ROS-mediated inactivation of PI3K/AKT/mTOR pathway, arrest of the cell cycle at G1 phase and induction of molecular mechanisms of caspases-dependent apoptosis. In addition, the docking analysis and quantum mechanics studies performed here hypothesize that the effect of triple-drug combination could have been attributed by their difference in molecular interactions, that maybe due to varying electrostatic potential. Thus, repurposing metformin and epigallocatechin gallate and concurrent administration with temozolomide would serve as a prospective therapy in glioma patients.

Methods: The study consisted of 4 groups of 20 women, including the healthy control. The patients of group 1 comprised of stages I and II, group 2: stage III and group 3: stage IV of the disease. High sensitive C-reactive protein (hsCRP) and hepcidin were estimated by enzyme linked immunosorbent assay and ferritin by chemiluminescence immunoassay. The study was carried out in 2018 at Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry-6, India. Results: The breast cancer disease progression correlated negatively with hemoglobin (Hb) (r= -0.6937, p 3.9516 was used to identify the possibility of breast cancer utilizing the receiver operator curve values (area under curve [AUC]=0.997, sensitivity: 96.7, specificity:100). Ferritin values >103.4 were used to differentiate stage 4 from stage 3 of the disease (AUC: 0.893, sensitivity: 100, specificity: 85). Conclusion: Ferritin and ferritin/Hb are helpful in the differential diagnosis of stages of breast cancer.

BACKGROUND: Cytarabine based therapy has been the standard consolidation regimen for AML (acute myeloid leukemia) for decades. However, the optimal dose, regimen and schedule is not known. HIDAC (high dose cytarabine at 18 g/m(2)) has been the conventional standard, however, recent studies have shown that intermediate doses of cytarabine (IDAC) have equal efficacy and lesser toxicities. METHODS: We retrospectively analysed 75 AML patients who entered consolidation out of 167 patients who underwent induction therapy between 2014 and 2018. HIDAC (at 18 g/m(2)) was given to 39 patients and 36 patients received IDAC at 9 g/m(2). RESULTS: Median age was 28 years (range 2–60). Male: female ratio was 1.02. More courses were administered in out-patient setting in IDAC group 61% (n = 58/95 courses) than in HIDAC 29% (n = 29/101 courses); p

Background Treatment protocols for acute lymphoblastic leukemia (ALL) have evolved over time to give excellent cure rates in children and moderate outcomes in adults; however, little is known how delays in chemotherapy affect long-term survival. Objectives To find the association of delays during different treatment phases on the survival outcomes. Materials and Methods Data from 149 ALL cases treated between 2009 and 2015 were retrospectively analyzed. Treatment course in commonly used protocols was divided into three phases—induction, consolidation (postremission), maintenance, and also a combined intensive phase (induction plus consolidation) for the purpose of analysis, and delay in each phase was defined based on clinically acceptable breaks. Analysis was done to find the impact of treatment delay in each phase on the survival outcomes. Results The median age was 12 years (range, 1–57). Multi-center Protocol-841 (MCP-841) was used for 72%, German Multicenter Study Group for Adult ALL (GMALL) for 19%, and Berlin, Frankfurt, Muenster, 95 protocol (BFM-95) for 9% of patients. Delay in induction was seen in 52%, consolidation in 66%, and during maintenance in 42% of patients. The median follow-up was 41 months, and 3-year survival outcomes for the entire cohort were event-free survival (EFS)—60%, relapse-free survival (RFS)—72%, and overall survival (OS)—68%. On univariate analysis, delay in induction adversely affected EFS (hazard ratio [HR] = 1.78, p = 0.04), while delay in intensive phase had significantly worse EFS and RFS (HR = 2.41 [p = 0.03] and HR = 2.57 [p = 0.03], respectively). On separate analysis of MCP-841 cohort, delay in intensive phase affected both EFS (HR = 3.85, p = 0.02) and RFS (HR = 3.42, p = 0.04), whereas delay in consolidation significantly affected OS with (HR = 4.74, p = 0.04) independently. Conclusion Treatment delays mostly in intensive phase are associated with worse survival in ALL; attempts should be made to maintain protocol-defined treatment intensity while adequately managing toxicities.

We explored the prognostic impact of simple indices that reflect the immunological milieu (neutrophils to lymphocyte ratio [NLR] and systemic immune-inflammation [SII]) in 49 platinum-resistant relapsed ovarian cancer patients. The median progression-free survival (PFS) and overall survival (OS) were 4 and 8 months, respectively. Patients with a lower NLR (≤2.89) had a better PFS (5 vs. 2 months [p = 0.02]) and OS (9 vs. 5 months [p = 0.20]). Factors associated with a worse PFS were NLR > 2.8 (hazard ratio [HR] =2.32, p = 0.02) and SII > 639 (HR =3.70, p = 0.002). SII > 639 independently predicted PFS (HR =4.13, p = 0.03). Future studies should study the validity of inflammatory markers and could consider incorporating it as a biomarker in clinical trials.

Background: Patients with platinum-resistant ovarian cancer (PROC) have limited therapeutic options and poor survival. There is a need for the development of newer therapies. Sodium valproic acid (VPA) is a short-chain fatty acid histone deacetylase (HDAC) inhibitor with antitumor activity in preclinical models of PROC. Synergism with conventional cytotoxic agents like etoposide has been demonstrated. Methodology: In this prospective, single-arm, open-label, phase 2 study, we included patients ≥18 years with histologically or cytologically confirmed PROC and Eastern Cooperative Oncology Group performance status (ECOG-PS) 0-3. Patients received oral VPA 60 mg/kg/day in three divided doses for three days (D1-D3), followed by oral etoposide 50 mg once daily for two consecutive weeks (D4-D17). Serum samples were collected to assess peak VPA drug levels. The primary endpoint was the overall response rate (ORR). The secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity. We sought to show an improvement in response rate from 25% (historically with oral etoposide) to 40% with the addition of VPA. Results: 27 patients were enrolled in the study, and 18 [median age: 52 (45-59) years; serous histology:17(94%); ECOG-PS 2 or 3: 14 (78%)] were evaluable for the response after four months. Nine patients were lost from follow-up before achieving the primary endpoint (mainly due to Covid-related lockdown issues). The median number of prior lines of treatment was 2 (1-3). ORR was 0% according to GCIG criteria. The disease was stable in two patients [clinical benefit rate (CBR) of 11%]. The median OS and PFS were seven months and two months, respectively. Grade ≥3 adverse events were reported in 6 (33%) patients. Conclusion: The addition of valproic acid to oral etoposide in patients with PROC and poor general condition was not helpful and failed to improve responses compared to those historically achieved with single-agent etoposide.

Background: Lung is one of the commonest site for malignant neoplasms, both primary and metastatic. Primary lung malignancies are presently heading the list of common cancers worldwide and accounts for more death than any other cancer. In lung cancer, diagnosis of histological type is of great significance to determine the prognosis and for planning the treatment. Radiology and imaging plays an integral part in diagnosis, management, staging and follow-up of lung cancer patients. Moreover, radiology can give vital clues towards histological diagnosis of the malignancy. Our study aims to analyse the clinical, radiological and histological patterns occurring in patients with primary lung cancer. Materials and Methods: A total of 116 patients with clinical and radiological features suggestive of primary lung cancer were enrolled. Diagnosis of lung cancer was established histopathologically. Clinico-pathological profile and histopathological analysis was done individually for all patients. Results: Our study included a total of 116 cases with 84 males (72%) and 32 (28%) female patients with a median age of 60 years (range 19-90 years). The most common histological type of lung cancer was adenocarcinoma, in 79(69.82%) of patients followed by squamous cell carcinoma in 22 patients (18.96%). Adenocarcinoma was the most common type among both males and females. Also adenocarcinoma was the commonest histological pattern among non-smokers. The most common clinical presentation was cough with expectoration. Radiologically most common feature was mass lesion (86.2%). Seventy four patients (63.78%) with non-small cell lung cancer had metastatic disease, the most common being malignant pleural effusion. Six out of seven patients of small cell cancer had extensive stage. Conclusions: Adenocarcinoma is the commonest histological pattern of lung cancer even in smokers. Lung cancer is not necessarily a disease of old age. Majority of the patients still present in advanced stages. A g

The study aimed at identifying the profile of gut colonization of patients with acute leukemia who underwent induction chemotherapy and its association with induction events and outcome. Baseline bacterial stool culture with resistance pattern of isolates were recorded. Multi-drug resistance was defined as resistance to at least two antibiotic classes including beta lactam and fluoroquinolones. During induction chemotherapy, blood and clinically indicated cultures were taken during febrile neutropenic episodes. Association studies were done between gut colonization and induction events/outcome. Among 109 patients enrolled, 71 (65.13%) patients undergoing induction chemotherapy were colonized with bacteria, with nearly 50% of colonizers harboring multi-drug resistant bacteria. Organisms isolated from stool pre-induction were mostly gram negative (98%), with Escherichia coli and Klebsiella pneumoniae being the commonest. 65.13% patients developed febrile neutropenia. Overall multi-drug resistant positivity during febrile neutropenia was 70.14%. Concordance of 8.45% was observed between isolates from stool and organisms isolated from cultures during febrile neutropenia. There were significant proportion of gut colonized gram-negative multi-drug resistance bacteria among patients with acute leukemia. There was a low concordance rate between baseline stool isolates and subsequent cultures during the induction. There was no significant association between gut colonization and induction events/outcomes studied.

Metaplastic Breast Carcinoma (MBC) is a rare heterogeneous group of tumors, the incidence of which is less than 1% of breast tumors. These are a unique set of tumors with varying subtypes, poor prognosis, and an increased chance of distant metastasis. We aimed to study the clinical, histomorphological, and immunohistochemical (IHC) features of Metaplastic Breast Carcinoma (MBC). This was a descriptive study of cases diagnosed as MBC at a tertiary care center in Southern India from January 2015 to December 2019. A total of 20 cases were diagnosed whose clinical, histomorphological, and IHC features were studied. PD-L1and CD8 IHC were performed and analyzed in 12 cases. The median age of presentation was 50 years. Seventy percent (14/20) patients were postmenopausal women. On excision, 75% (15/20) showed mixed typed MBC, the remainder showing epithelial type MBC. Metastasis to axillary lymph node was seen only in 20% (4/20) of the cases. Thirty percent (6/20) of the cases belonged to stage 3 disease and 5% (1/20) of the cases belonged to stage 4 disease with liver metastasis. Estrogen receptor (ER), Progesterone receptor (PR) were negative in all the cases, Her2neu was positive in three cases. Ki67 labeling index was greater than 14% in all the cases. PD-L1was positive in 41.5% of the cases and intratumoral CD8 positive lymphocytes were increased in 83.3% of the cases. MBCs are tumors occurring in elderly postmenopausal women, presenting with large tumor size, have lesser chances of lymph node metastasis, and a higher chance of recurrence and hematogenous spread. They are negative for ER, PR, Her-2 neu, with a high Ki67 index and a strong PDL-1 expression.
