Abstract
PURPOSE Hand-foot syndrome (HFS) is a dose-limiting side effect of capecitabine. Celecoxib prevents HFS by inhibiting cyclooxygenase-2 (COX-2) that is upregulated because of the underlying associated inflammation. However, systemic side effects of celecoxib have limited routine prescription. Topical diclofenac inhibits COX-2 locally with minimal risk of systemic adverse events. Therefore, we conducted this study to assess the efficacy of topical diclofenac in the prevention of capecitabine-induced HFS. METHODS In this single-site phase III randomized double-blind trial, we enrolled patients with breast or GI cancer who were planned to receive capecitabine-based treatment. Participants were randomly assigned in a 1:1 ratio to receive topical diclofenac or placebo gel for 12 weeks or until the development of HFS, whichever occurred earlier. The primary end point was the incidence of grade 2 or 3 HFS (Common Terminology Criteria for Adverse Events version 5), which was compared between the two groups using simple logistic regression. RESULTS In total, 264 patients were randomly assigned to receive topical diclofenac gel (n = 131) or placebo (n = 133). Grade 2 or 3 HFS was observed in 3.8% of participants in the diclofenac group compared with 15.0% in the placebo group (absolute difference, 11.2%; 95% CI, 4.3 to 18.1; P = .003). Grade 1-3 HFS was lower in the diclofenac group than in the placebo group (6.1% v 18.1%; absolute risk difference, 11.9%; 95% CI, 4.1 to 19.6). Capecitabine dose reductions because of HFS were less frequent in the diclofenac group (3.8%) than in the placebo group (13.5%; absolute risk difference, 9.7%; 95% CI, 3.0 to 16.4). CONCLUSION Topical diclofenac prevented HFS in patients receiving capecitabine. This trial supports the use of topical diclofenac to prevent capecitabine-associated HFS.

Abstract
Introduction Breast cancer is the most common cancer among Indian females. There is limited data on germline profiling of breast cancer patients from India. Objective The objective of the current study was to analyse the frequency and spectrum of germline variant profiles and clinicopathological characteristics of breast cancer patients referred to our Familial Cancer Clinic (FCC). Materials and methods It is a single-centre audit of patients with a confirmed diagnosis of breast carcinoma referred to our FCC from January 2017 to 2020. All patients underwent pretest counselling. Genetic testing was done by multigene panel testing by next-generation sequencing along with reflex multiplication ligation-dependent probe amplification for BRCA1 and 2. The variants were classified based on American College of Medical Genetics guidelines. Demographic and clinicopathological details were extracted from the case record files. Results One hundred and fifty-five patients were referred to the FCC and underwent pretest counselling. A total of 99 (63.9%) patients underwent genetic testing. Among them, 62 patients (62/99 = 62.6%) had a germline variant. A pathogenic/likely pathogenic (P/LP) germline variant was identified in 41 (41.4%) of the patients who underwent testing. Additional variants of unknown significance (VUS) were identified in seven patients who also carried a P/LP variant. VUS alone was detected in 21 patients (21/99 = 21.2%). Among the P/LP pathogenic variants (PV), BRCA 1 PV were seen in 27 patients (65.8%), BRCA 2 variants in 7 patients (17.1%), ATM variants in 3 patients (7.3%) and RAD51, TP53, CHEK2 and HMMR in 1 patient each. Variants were significantly more common in patients with a family history (FH) of malignancy than those without FH (58.5% versus 29.5%; p = 0.013). Age and triple-negative histology were not found to be significantly associated with the occurrence of P/LP PVs. Conclusion We report a 41% P/LP variant rate in our selected cohort of breast cancer patients, with variants in BRCA constituting 83% and non-BRCA gene variants constituting 17%.

Abstract
PURPOSE The upregulation of fibroblast activation protein (FAP) expression has been observed in various cancers, including metastatic breast carcinoma, prompting research into small molecule inhibitors for both diagnostic and therapeutic purposes. While the diagnostic value of PET/CT imaging using 68 Ga- or 18F-labelled FAPi-monomers in breast cancer diagnosis is well-established, there is a significant need for therapeutic analogs. This retrospective study aimed to assess the safety and effectiveness of [177Lu]Lu-DOTAGA.FAPi dimer radionuclide therapy in patients with advanced-stage breast cancer who had previously undergone [68 Ga]Ga-DOTA.SA.FAPi PET/CT scans to confirm the expression of FAP. MATERIALS AND METHODS Between November 2020 and March 2023, a compassionate treatment approach was utilized to administer [177Lu]Lu-DOTAGA.FAPi dimer radionuclide therapy to heavily pretreated patients with advanced breast cancer. Nineteen patients (18 females, 1 male) with metastatic breast cancer participated in the study, with an average age of 44.6 ± 10.7 years. The therapy was administered at intervals of 8 to 12 weeks, and the median follow-up duration was 14 months. The primary objective of the study was to assess molecular response using [68 Ga]Ga-DOTA.SA.FAPi PET/CT scans, with response evaluation based on the PERCIST criteria. Secondary endpoints included overall survival (OS), progression-free survival (PFS), clinical response assessment, and safety evaluation using CTCAE v5.0 guidelines. RESULTS A total of 65 cycles were administered, with a mean cumulative activity of 19 ± 5.7 GBq (510 ± 154 mCi) ranging from 11 to 33.3 GBq (300 to 900 mCi) of [177Lu]Lu-DOTAGA.FAPi dimer. The number of cycles ranged from 2 to 6, with a median of 3 cycles. The treatment protocol consisted of different numbers of cycles administered to the patients: specifically, two cycles were given to five patients, three cycles to nine patients, four cycles to one patient, and six cycles to four patients. Most patients had invasive/infiltrative ductal carcinoma (94.7%), while a small percentage had invasive lobular carcinoma (5.3%). All patients had bone metastases, and five of them also had liver involvement, while seven had brain metastases. Response assessment using [68 Ga]Ga-DOTA.SA.FAPi PET/CT scans showed that 25% of the 16 patients evaluated had partial remission, while 37.5% exhibited disease progression. According to the VAS response criteria, 26.3% achieved complete response, 15.7% had partial response, 42% showed minimal response, 11% had stable disease, and 5% had no response. The clinical disease control rate was promising, with 95% of patients achieving disease control. The clinical objective response rate was 84%. The median follow-up period was 14 months. At the time of analysis, the median overall survival was 12 months, and the median progression-free survival was 8.5 months. Notably, no severe hematological, renal, or hepatic toxicities, electrolyte imbalances, or adverse events of grade 3 or 4 were observed during the study. CONCLUSION The findings suggest that [177Lu]Lu-DOTAGA.FAPi dimer therapy is well-tolerated, safe, and effective for treating end-stage metastatic breast cancer patients. [177Lu]Lu-DOTAGA.FAPi dimer treatment demonstrated promising efficacy in patients with advanced breast cancer, as indicated by high disease control rates, favorable response outcomes, and acceptable safety profile. Further research and longer follow-up are warranted to assess long-term outcomes and validate these findings.

Abstract
OBJECTIVES Dexamethasone sparing strategies have shown success. The feasibility of a dexamethasone-free antiemetic strategy remains undetermined. A prospective, single-arm, pilot study was planned to determine the efficacy of an olanzapine-based, dexamethasone-free, three-drug antiemetic regimen. METHODS Chemotherapy naïve, adult patients (≥18 years) who received ondansetron, aprepitant and olanzapine during the first cycle of highly emetogenic chemotherapy were enrolled. The primary endpoint was the rate of complete response (CR: no vomiting and no use of rescue medications) during the overall period (0-120 hours). RESULTS Out of the total of 101 patients enrolled, most were women (82%) and received anthracycline cyclophosphamide (73%) combination therapy. The rate of CR for the overall period was 65% (95% CI 55.2% to 74.5%). The rate of CR for the acute and delayed period was 79% (95% CI 70% to 86.7%) and 76% (95% CI 66.7% to 84.1%). The rate of nausea control rates for the acute, delayed and overall periods were 34%, 29% and 24%, respectively. The grade I, II and III sedation rates over the 5 days were 8%, 5% and 1%, respectively. CONCLUSIONS The dexamethasone-free antiemetic strategy showed modest efficacy with low incidence of clinically significant somnolence. There is a need to prospectively investigate the role of dexamethasone in the era of newer potent antiemetics in a randomised fashion. TRIAL REGISTRATION NUMBER CTRI/2021/07/034813.

Abstract
Background Patients with chronic lymphocytic leukemia (CLL) have a higher risk of developing other malignancies (OMs) compared to the general population. However, the impact of CLL-related risk factors and CLL-directed treatment is still unclear and represents the focus of this work. Methods We conducted a retrospective international multicenter study to assess the incidence of OMs and detect potential risk factors in 19,705 patients with CLL, small lymphocytic lymphoma, or high-count CLL-like monoclonal B-cell lymphocytosis, diagnosed between 2000 and 2016. Data collection took place between October 2020 and March 2022. Findings In 129,254 years of follow-up after CLL diagnosis, 3513 OMs were diagnosed (27.2 OMs/1000 person-years). The most common hematological OMs were Richter transformation, myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Non-melanoma skin (NMSC) and prostate cancers were the most common solid tumors (STs).The only predictor for MDS and AML development was treatment with fludarabine and cyclophosphamide with/without rituximab (FC ± R) (OR = 3.7; 95% CI = 2.79-4.91; p < 0.001). STs were more frequent in males and patients with unmutated immunoglobulin heavy variable genes (OR = 1.77; 95% CI = 1.49-2.11; p < 0.001/OR = 1.89; 95% CI = 1.6-2.24; p < 0.001).CLL-directed treatment was associated with non-melanoma skin and prostate cancers (OR = 1.8; 95% CI = 1.36-2.41; p < 0.001/OR = 2.11; 95% CI = 1.12-3.97; p = 0.021). In contrast, breast cancers were more frequent in untreated patients (OR = 0.17; 95% CI = 0.08-0.33; p < 0.001).Patients with CLL and an OM had inferior overall survival (OS) than those without. AML and MDS conferred the worst OS (p < 0.001). Interpretation OMs in CLL impact on OS. Treatment for CLL increased the risk for AML/MDS, prostate cancer, and NMSC. FCR was associated with increased risk for AML/MDS. Funding AbbVie, and EU/EFPIAInnovative Medicines Initiative Joint Undertaking HARMONY grant n° 116026.

Abstract
BACKGROUND Breast cancer (BC) is the most common malignancy with very high incidence and relatively high mortality in women. The PIK3CA gene plays a pivotal role in the pathogenicity of breast cancer. Despite this, the mutational status of all exons except exons 9 and 20 still remains unknown. METHODS This study uses the whole exome sequencing (WES) based approach to identify somatic PIK3CA mutations in Indian BC cohorts. The resultant hotspot mutations were validated by droplet digital PCR (ddPCR). Further, molecular dynamics (MD) simulation was applied to elucidate the conformational and functional effects of hotspot position on PIK3CA protein. RESULTS In our cohort, PIK3CA showed a 44.4% somatic mutation rate and was among the top mutated genes. The mutations of PIK3CA were confined in Exons 5, 9, 11, 18, and 20, whereas the maximum number of mutations lies within exons 9 and 20. A total of 9 variants were found in our study, of which 2 were novel mutations observed on exons 9 (p.H554L) and 11 (p.S629P). However, H1047R was the hotspot mutation at exon 20 (20%). In tumor tissues, there was a considerable difference between copy number of wild-type and H1047R mutant was detected by ddPCR. Significant structural and conformational changes were observed during MD simulation, induced due to point mutation at H1047R/L position. CONCLUSIONS The current study provides a comprehensive view of novel as well as reported single nucleotide variants (SNVs) in PIK3CA gene associated with Indian breast cancer cases. The mutation status of H1047R/L could serve as a prognostic value in terms of selecting targeted therapy in BC.

Abstract
BACKGROUND Dose-dense adjuvant chemotherapy has been shown to be associated with improved long-term survival outcomes in triple-negative breast cancer (TNBC). However, there is a lacuna of data on the benefits of dose-dense neoadjuvant chemotherapy (NACT) in TNBC. METHODS This retrospective study included 217 newly diagnosed cases of TNBC treated with a sequential anthracycline and taxane-based NACT, followed by definitive surgery. Study groups consisted of 137 patients who received 3-weekly conventional chemotherapy (cNACT group) and 80 patients with 2-weekly dose-dense NACT (ddNACT group). Pathological complete response (pCR) rates, relapse-free survival (RFS), overall survival (OS), and grade-3/4 chemotoxicities were compared across the groups. RESULTS No significant difference in the pCR rate (32.8% versus 31.3%; P = 0.808) was observed across the study groups. Relapse rate was lower in the ddNACT group compared to the cNACT group (odds ratio [OR]: 0.51, 95% confidence interval [CI]: 0.27-0.95). However, ddNACT had no RFS advantage over conventional chemotherapy (median RFS: not reached versus 56.1 months in cNACT; hazard ratio: 0.90, 95% CI: 0.52-1.53). OS was also comparable in both the groups with a 3-year survival rate of 78.8% (95% CI: 60.9-89.2) in the ddNACT group versus 84.3% (95% CI: 74.8-90.4) in the cNACT group. Younger age, menopause, the Eastern Cooperative Oncology Group ECOG status, and pCR were significantly associated with OS in our cohort. Grade-3 toxicities were comparable in both groups. CONCLUSIONS This observational study focusing on ddNACT among TNBC patients demonstrated significant differences in the relapse rate with no survival benefits. Differential effects of ddNACT by tumor presentation (early vs. late), tumor size, tumor biology, and cost-benefits of granulocyte colony-stimulating factor support with such regimens need further exploration.

Abstract
INTRODUCTION Bendamustine-rituximab (BR) is the preferred regimen for the treatment of naïve follicular lymphoma (FL). Recently, lenalidomide-rituximab (LR), a chemotherapy-free protocol, has shown a good response rate in advanced FL. These regimens have never been compared in a randomized controlled trial for treatment-naïve FL in Indian patients. MATERIALS AND METHODS This Phase III open-label randomized controlled trial was conducted to compare the efficacy and safety of BR and LR. Treatment-naïve patients older than 18 years of age, ECOG PS (Eastern Cooperative Oncology Group Performance Status) ≤2, who were diagnosed with FL (Stages II-IV) were included in this study. Patients were randomized in a 1:1 ratio to receive six cycles of BR (bendamustine 90 mg/m 2 Days 1-2 and rituximab 375 mg/m 2 Day 1) every 4 weeks or LR (lenalidomide 20 mg Days 1-21 and rituximab 375 mg/m 2 ) every 4 weeks. The primary end point was complete response (CR) and secondary end points were overall response rate (ORR) and toxicity. RESULT We enrolled 40 patients, 20 in each group with a median age of 53 years. The CR rate was 60% and 20% in BR and LR arms, respectively ( P = 0.01); however, the ORR was 88.8% and 87.3% in BR and LR arms, respectively ( P = 1.0). Anemia (35% versus 10%), skin rash (35% versus 30%), diarrhea (30% versus 10%), vomiting (20% versus 10%), nephrotoxicity (15% versus 0%), and transaminitis (10% versus 0%) were more in LR than in BR, and thrombocytopenia was higher in the BR than in the LR group but statistically not different. All grade toxicities were seen in 90% and 45% in LR and BR, respectively ( P = 0.05), but there was no significant difference in Grade 3 or 4 toxicity between the BR and the LR regimens (20% versus 25%). CONCLUSION The ORR was similar in both the arms; however, the CR rate was significantly higher in the BR arm. BR was better tolerated than LR.(CTRI/2016/05/006904).

Abstract
There is paucity of literature regarding the demography, histopathology, management, and outcomes of bilateral breast cancer (BBC). We present our experience of treating 127 BBC with multimodality management. An audit of prospectively maintained computerized breast cancer database of the department of surgical oncology at a tertiary care center was performed. Demography, clinical profile, molecular sub-types, treatment patterns, and outcomes were analyzed. A total 127 patients presented with BBC between 1992 and 2019. Ninety-four had metachronous (MBBC) and 33 had synchronous breast cancer (SBBC). Most contralateral breast cancer (CBC) patients had early-stage breast cancer in comparison to the index side cancer (37% vs 32%). Ninety-four patients underwent bilateral mastectomy and only 18 patients underwent bilateral breast conservation. Seventy-one patients undergoing BCS and surgery for LABC were given postoperative radiotherapy. All patients received adjuvant chemo- and/or hormonal therapy both for index and CBC based on the stage and hormone receptor status. Thirty-three percent of patients had either locoregional or distant relapse. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) of the entire cohort were 86.6% and 68.4% respectively. There was no difference in the OS and DFS between SBBC and MBBC. The incidence of BBC is expected to increase with effective diagnostic and therapeutic interventions and improving survival. Patients require individualized treatment planning in a multidisciplinary treatment setting.

Abstract
Malignancy in heart transplant recipients is a grave complication. Post-transplant lymphoproliferative disorder (PTLD) is the second most common tumour in adults and commonest in children. The incidence varies with the transplanted organ from 1 to 2% following kidney transplantation to as high as 10% following thoracic organ transplantation due to different immunosuppression intensity. PTLD include a wide spectrum of diseases ranging from benign proliferation of lymphoid tissue to frank malignancy with aggressive behaviour (lymphoma). Epstein-Barr virus (EBV) infection and prolonged immunosuppressant therapy are implicated in the pathogenesis of PTLD. The incidence of PTLD varies from 2.6% at 1 year to 28% at 10 years post-transplant. Seronegativity for EBV in recipients with seropositive donors increases the risk of PTLD in recipients. The majority of early-onset PTLDs (85%) are of B-cell origin and associated with EBV. Timely and accurate diagnosis with histological examination of lymphoid tissue is essential for early intervention. Reduction of immunosuppressive therapy (IST) and rituximab usually are effective in remission of PTLD. In resistant cases, chemotherapy is given with or without rituximab. Adoptive T-cell transfer represents a promising therapeutic approach. Early PTLD respond well to lowering immunosuppression and has a favourable prognosis compared to late PTLD. Five-year survival is 30% for high-grade lymphomas. The prognosis of EBV-negative lymphomas is worse. One out of 40 heart transplant recipients followed up in our centre developed PTLD. He was treated to remission and we describe this case here.

Abstract
Among all the subtypes of breast cancer, triple-negative breast cancer (TNBC) has been associated with the worst prognosis. Recently, for many solid tumors (including breast cancer) metabolic reprogramming has appeared as a cancer cell hallmark, and the elevated glycolytic pathway has been linked to their aggressive phenotype. In the present study, we evaluated the prognostic and therapeutic relevance of PFKFB3 (6-phosphofructo-2- kinase/fructose-2,6-bisphosphatase) in TNBCs. Prognostic significance of PFKFB3 expression was evaluated in overall breast cancers as well as in TNBCs. PFKFB3 inhibitor (3PO potent analogue i.e., PFK15) cytotoxicity in TNBC cell lines (MDA-MB-231 and MDA-MB-468) was analyzed using an MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Cancer cell physiological characteristics like clonogenicity and migration were also investigated after PFK15 treatment. As fructose-2,6-bisphosphate (F-2,6-BP), has been associated with increased PFK-1 activity, the effect of PFKFB3 inhibition by PFK15 was investigated on two major isoforms of phosphofructokinase-1 (PFK-1) in breast cancer, that is, phosphofructokinase-platelet type (PFKP) and phosphofructokinase-liver type (PFKL) (relevant to breast cancer). For PFKL inhibition, the siRNA approach was used. PFKFB3 expression was significantly correlated with inferior overall survival in breast cancer patients including TNBCs. PFK15 treatment in TNBC cells (i.e., MDA-MB-231 and MDA-MB-468) resulted in a decreased PFKP expression, thereby leading to reduced colony formation ability, migration rate, and extracellular lactate levels. However, to our surprise PFK15 treatment in both TNBC cells also resulted in elevated PFKL levels. Our results demonstrated that the combinatorial inhibition of PFK15 with siPFKL was more effective in TNBC cells, as it led to a decrease in colony formation ability, migration rate, extracellular lactate levels, and PFK-1 activity when compared with individual treatments. Using bona fide PFKFB3 inhibitor, that is, AZ67, we further show that AZ67 treatment to TNBC cells has no effect either on the expression of PFKP and PFKL, or on the lactate production. In summary, our present in vitro study demonstrated that 3PO derived PFK15 mechanism of action is totally different from AZ67 in TNBC cells. However, we advocate that the PFK15-mediated inhibition (along with PFKL) on the TNBCs migration, colony formation, and PFK-1 activity can be further explored for the therapeutic advantage of TNBC patients.

Abstract
ABSTRACT Extranodal Natural killer/T (NK/T) cell lymphoma nasal type is an aggressive non-Hodgkin lymphoma and has a constant association with Epstein-Barr virus (EBV) infection. Approximately more than 75% cases are located in upper aero-digestive tract, of which stomach is a very rare site. Very few cases of gastric extranodal NK/T cell lymphoma have been reported in the literature. A 22-year-old male patient presented with complaints of abdominal pain and hematemesis. Endoscopy showed a large ulcer in the stomach. Partial gastrectomy done and histopathology showed transmural infiltration by intermediate size atypical lymphoid cells which are immunopositive for CD3, CD56, TIA, EBV-encoded RNA (EBER) and negative for CD4, CD8, CD20. A diagnosis of extranodal NK/T cell lymphoma nasal type was made.

Abstract
BACKGROUND Neoadjuvant chemotherapy (NACT) with human epidermal growth factor receptor 2 (HER2) blockade is the preferred approach for treating early and locally advanced HER2-positive breast cancer. There is a lack of robust data comparing pathological complete response (pCR) and survival outcomes in anthracycline-free and anthracycline-containing regimens with single HER2-targeted therapy. OBJECTIVES The present study retrospectively evaluated pCR between two groups: Single HER2-targeted therapy with and without anthracycline. METHODS A total of 215 HER2-positive female breast cancer patients were analyzed who received eitheranthracycline-containing EC-TH (epirubicin and cyclophosphamide, followed by docetaxel and trastuzumab)oranthracycline-free TCH [docetaxel, carboplatin and trastuzumab]. Univariate and multivariate analyses identified prognostic factors for survival and pCR.Kaplan Meier survival curvesdetermined disease-free survival(DFS) and overall survival (OS). RESULTS Baseline characteristics were comparable in both treatment groups. The pCR rate was 30.8% in the anthracycline-containing EC-TH group and 40.9% in the anthracycline-free TCH group; p = 0.140. Disease-free survival at 3 years (65.8% vs. 58.4%) and 5 years (49.2% vs. 55.2%) was similar between EC-TH and TCH groups, respectively (log-rank p = 0.550). Three-year (95.5% vs. 92.5%) and five-year (84.4% vs. 80.8%) OSwere also comparable between both groups (log-rank p = 0.485). The anthracycline-containing EC-TH group had a higher incidence of febrile neutropenia (6.4%. vs. 3.6%) and cardiac adverse events (7.7% vs. 4.4%) than the anthracycline-free TCH group. CONCLUSION Neoadjuvant anthracycline-free chemotherapy has similar pCR and survival outcomeswith favourable cardiac and non-cardiac adverse effect profiles compared with anthracycline-containing chemotherapy.

Abstract
Primary splenic lymphomas are rare with the majority of lymphomas in spleen being secondary to an extra-splenic lymphoma. We aimed to analyze the epidemiological profile of the splenic lymphoma and review the literature. This was a retrospective study including all splenectomies and splenic biopsies from 2015 to September 2021. All the cases were retrieved from Department of Pathology. Detailed histopathological, clinical and demographic evaluation was done. All the lymphomas were classified according to WHO 2016 classification. A total of 714 splenectomies were performed for a variety of benign causes, as part of tumor resections and for the diagnosis of lymphoma. Few core biopsies were also included. A total of 33 lymphomas diagnosed in the spleen, primary splenic lymphomas constituted 84.84% (n = 28) of the cohort with 5 (15.15%) having the primary site elsewhere. The primary splenic lymphomas constituted 0.28% of all the lymphomas arising at various sites. Adult population (19-65 years) formed the bulk (78.78%) with a slight male preponderance. Splenic marginal zone lymphomas (n = 15, 45.45%) comprised of major proportion of cases followed by primary splenic diffuse large B-cell lymphoma (n = 4, 12.12%). Splenectomy was the main course of treatment for SMZL with a good overall outcome, with chemotherapy ± radiotherapy forming the mainstay in other lymphomas. Lymphomas in spleen can be infiltrative or a primary, hence proper clinic-radiological and pathological evaluation is required. Appropriate management is guided by the precise and detailed evaluation by the pathologist, requiring understanding of the same.

Abstract
Early breast cancer is among the most common cancers worldwide. Recent advances continue to improve outcomes and increase long-term survivorship. However, therapeutic modalities are deleterious for patients' bone health. While antiresorptive therapy may partially negate this, consequent reduction in rates of fragility fractures remains unproven. Selective prescription of bisphosphonates or denosumab may be an amicable middle ground. Recent evidence also suggests a possible role of osteoclast inhibitors as adjuvant therapy, but the evidence is modest at best. In this narrative clinical review, we explore the impact of various adjuvant modalities on bone mineral density and fragility fracture rates of early breast cancer survivors. We also review optimal patient selection for antiresorptive agents, their impact on rates of fragility fractures, and the possible role of these agents as adjuvant therapy.

Abstract
The study was designed to review the demographic, clinical, and pathologic characteristics of follicular helper T cells (TFH)-derived nodal PTCL in India including angioimmunoblastic T-cell lymphoma (AITL), peripheral T-cell lymphoma (PTCL) with follicular helper T cell phenotype (P-TFH), and follicular T-cell lymphoma with additional immunohistochemistry (IHC) and RHOAG17V mutational analysis, as well as their impact on survival. This retrospective study included 88 cases of PTCL that were reclassified using IHC for TFH markers (PD1, ICOS, BCL6, and CD10) and dendritic-meshwork markers (CD21, CD23). Cases of TFH cell origin were evaluated for RHOAG17V mutation using Sanger sequencing and amplification-refractory mutation system-polymerase chain reaction (PCR) (validated using cloning and quantitative PCR) with detailed clinicopathologic correlation. Extensive re-evaluation with added IHC panel resulted in a total of 19 cases being reclassified, and the final subtypes were AITL (37 cases, 42%), PTCL-not otherwise specified (44, 50%), P-TFH (6, 7%), and follicular T-cell lymphoma (1, 1%). The presence of at least 2 TFH markers (>20% immunopositivity) determined the TFH origin. AITL patients tended to be male and showed increased presence of B-symptoms and hepatosplenomegaly. Histomorphology revealed that 92% of AITL cases had pattern 3 involvement. Sanger sequencing with conventional PCR did not yield any mutation, while RHOAG17V was detected by amplification-refractory mutation system-PCR in AITL (51%, P =0.027) and P-TFH (17%), which was validated with cloning followed by sequencing. Cases of RHOAG17V-mutant AITL had a worse Eastern Cooperative Oncology Group performance status initially but fared better in terms of overall outcome ( P =0.029). Although not specific for AITL, RHOAG17V mutation shows an association with diagnosis and requires sensitive methods for detection due to low-tumor burden. The mutant status of AITL could have prognostic implications and translational relevance.

Abstract
BACKGROUND Peripheral neuropathy is a common dose-limiting side effect of paclitaxel. To date, there is no effective strategy to prevent paclitaxel-induced peripheral neuropathy. A recent small phase II study demonstrated the potential role of oral gabapentin in this setting. This phase III study is aimed to assess the efficacy of oral gabapentin in preventing paclitaxel-induced neuropathy. OBJECTIVE To compare the efficacy of oral gabapentin with placebo in preventing clinically significant peripheral neuropathy (NCI CTCAEv5.0 grade 2 or higher) in patients receiving paclitaxel. METHODS This is a randomized, placebo-controlled, double-blind, parallel-group superiority trial. The primary outcome is the development of grade 2 or higher chemotherapy-induced peripheral neuropathy. Secondary outcomes include any grade neuropathy, the percentage change in sensory nerve conduction velocities in peripheral nerves, time to development of any grade neuropathy, paclitaxel dose reductions and delays due to peripheral neuropathy, patient-reported outcomes, adverse events, and adherence to oral therapy. A total of 136 patients receiving paclitaxel will be randomly allocated (stratified by weekly vs. non-weekly administration) to receive either oral gabapentin or placebo till three weeks after the last dose of chemotherapy or occurrence of the primary outcome. CONCLUSION This study aims to find if oral gabapentin reduces the incidence of grade 2 or higher chemotherapy-induced peripheral neuropathy in patients receiving paclitaxel. TRIAL REGISTRATION The trial is registered prospectively with the Clinical Trials Registry of India (CTRI/2022/02/040030) on April 4, 2022.

Abstract
Recent evidence suggests that the prognostic impact of gene mutations in patients with chronic lymphocytic leukemia (CLL) may differ depending on the immunoglobulin heavy variable (IGHV) gene somatic hypermutation (SHM) status. In this study, we assessed the impact of nine recurrently mutated genes (BIRC3, EGR2, MYD88, NFKBIE, NOTCH1, POT1, SF3B1, TP53, and XPO1) in pre-treatment samples from 4580 patients with CLL, using time-to-first-treatment (TTFT) as the primary end-point in relation to IGHV gene SHM status. Mutations were detected in 1588 (34.7%) patients at frequencies ranging from 2.3-9.8% with mutations in NOTCH1 being the most frequent. In both univariate and multivariate analyses, mutations in all genes except MYD88 were associated with a significantly shorter TTFT. In multivariate analysis of Binet stage A patients, performed separately for IGHV-mutated (M-CLL) and unmutated CLL (U-CLL), a different spectrum of gene alterations independently predicted short TTFT within the two subgroups. While SF3B1 and XPO1 mutations were independent prognostic variables in both U-CLL and M-CLL, TP53, BIRC3 and EGR2 aberrations were significant predictors only in U-CLL, and NOTCH1 and NFKBIE only in M-CLL. Our findings underscore the need for a compartmentalized approach to identify high-risk patients, particularly among M-CLL patients, with potential implications for stratified management.

Abstract
We investigated the safety and efficacy of bendamustine-rituximab (BR) in previously untreated symptomatic and advanced CLL patients, as there is no data available on BR from the Indian subcontinent.This retrospective study included 120 consecutive treatment naïve patients with CLL without del (17p), who were registered at the Department of Medical Oncology, AIIMS between January 2010 and July 2018. Bendamustine was given at a dose of 90 mg/m2 on days 1 and 2, combined with rituximab 375 mg/m2 rituximab on day 1, every 28 days for up to 6 courses. Event-free survival (EFS) was defined as the date of treatment to date of relapse, disease progression, or death due to any cause.The median age was 57 years (range: 30-75 years). As per the clinical Rai stage, 30 (25%) patients were in stage II, 42 (35%) were in stage III and 48 (40%) were in stage IV. ZAP70 was positive (> 20%) in 50%, CD 38 was positive (> 30%) in 33%, and CD49d was positive (> 30%) in 49% of cases. Beta-2 microglobulin (B2M) was elevated (≥ 3.5 mg/L) in 80% of cases. Fifty-five cases (50%, n = 110) were IGHV mutated. The mean number of cycles was 5 (1-6). The overall response rate (ORR) seen with BR was 90% and complete response was 45%. Median progression-free survival was 24 months with a median follow-up period of 29 months. Haemoglobin (< 10 g/dL), elevated B2 M, unmutated IGHV had a statistically significant adverse impact on EFS on univariate analysis but on multivariate analysis, only IGHV mutation status was found to had significance on EFS. The median EFS was 27 months in IGHV mutated versus 18 months in IGHV unmutated-CLL patients (p = 0.001). Grade 3/4 neutropenia, thrombocytopenia, anemia, and infections were observed in 30.6%, 8%, and 12% respectively. The most common non-hematological toxicity was skin rash which was grade 1/2 in 24 (20%) cases and grade 3/4 in 12 (10%) cases. This is the largest study from India to demonstrate the safety and efficacy of BR in symptomatic CLL patients. BR is an effective and safe regimen in the first-line treatment of CLL. Unmutated-CLL patients have inferior EFS than mutated-CLL patients. Skin toxicity was the most common adverse effect seen in our population which was observed in around one-third of cases.

Abstract
To compare features of clinically defined subtypes of breast cancer on mammography (MG) and ultrasonography (USG). After obtaining approval from the institute ethics committee, a retrospective observational study was performed on biopsy-proven breast cancer patients who underwent baseline MG from 2016 to 2020. MG and USG features were evaluated and the patients were classified based on immunohistochemistry profile into luminal like (LL)-oestrogen receptor (ER)/progesterone receptor (PR) + , Her2neu-; basal like (BL)-ER/PR-, Her2neu-; Her2 like (HL)-Her2neu + . A total of 479 patients (mean age, 51.4 ± 11.7 years; all females) were included: LL-198 (41.3%), BL-121 (25.2%) and HL-160 (33.3%). On MG, round shape (21/115, 18.3%, p < 0.001); circumscribed (16/115, 13.9%, p < 0.001) and microlobulated margins (28/115, 24.4%) were associated with BL tumours. Associated suspicious calcifications (96/160, 60%, p < 0.001) and skin thickening or retraction (75/149, 50.3%, p < 0.001) were more common in HL. On USG, round shape (12/95, 12.8%, p = 0.005); circumscribed (8/94, 8.5%) and microlobulated margins (44/94, 46.8%) and posterior acoustic enhancement (7/95, 7.5%, p = 0.012) were associated with BL. The logistic regression analysis revealed that spiculated margins on MG favoured LL (OR: 8.5, p = 0.001); round shape (OR: 6.8), circumscribed (OR: 10.8) or microlobulated margins (OR: 3.5) (p < 0.001 for each) favoured BL; whereas associated features of calcifications (OR: 3.3) (p = 0.019) and skin retraction or thickening (OR: 1.8) (p < 0.001) favoured HL. On USG, circumscribed (OR: 5.9, p = 0.005) or microlobulated margins (OR: 3, p < 0.001) and posterior acoustic enhancement (OR: 9.5, p = 0.006) favoured BL. Clinically defined subtypes of breast cancer show significant differences in the imaging appearances on mammography and USG. BL tumours may not show the typical imaging features of malignancy, necessitating clinicopathological correlation for accurate diagnosis.

Abstract
CONTEXT Recent molecular studies have indicated the varied oncogenic pathways resulting in the subtypes of peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS), which affect prognosis and may have predictive value. OBJECTIVE To evaluate the immunohistochemistry (IHC) algorithm (Amador et al.) for the subtyping of PTCL, NOS and ascertain their relevance with correlation to the clinicopathological profile. DESIGN This 7-year (2015-2021) ambispective study included 43 patients with diagnoses of PTCL, NOS from the archives of the Department of Pathology (AIIMS, New Delhi). IHC for transcription factors GATA3 (>50% immunopositivity considered positive) and TBX21 (>20%) and their target proteins CCR4 (>50%) and CXCR3 (>20%) was performed followed by subtyping by two pathologists. Detailed clinicopathological correlation was done. MAIN OUTCOME MEASURES The association between the subtypes and clinical factors (demographics, performance status, organomegaly, IPI/PIT score, stage, marrow involvement), histologic features (monomorphous/polymorphous population), and survival (overall and progression-free survival) was analyzed. RESULTS With the application of the algorithm by Amador et al., the cases were categorized into the subtypes GATA3 (18), TBX21 (13), and unclassifiable (7). There was no significant association observed with the clinical parameters of the subtypes. Though an increased proportion of TBX21-subgroup cases showed a polymorphous population compared to the GATA3 subgroup with monomorphous population, no significant P-value was found. Two of the Lennert lymphomas were categorized in the GATA3 subgroup. On multivariate analysis, no significant difference was present for overall survival (P-value=0.149) and progression-free survival (P-value=0.066) amongst the IHC-defined subtypes; the trends suggest that the GATA3 subgroup has worse overall and progression-free survival. CONCLUSIONS The IHC-derived subtypes of GATA3 and TBX21 may have a role in prognostication and may guide further therapeutics aiding in better patient management of this aggressive group of lymphomas. The algorithm is reproducible, however some of the cases may be left unclassifiable and require further work up and gene expression profiling. The results trend toward the GATA3 subgroup having a monomorphous population with a worse overall prognosis, requiring a larger sample size for validation. The application of this algorithm in routine practice can help in risk stratification of the patients.

Abstract
PurposeBreast cancer (BC) presents a major public health challenge world-over including India. While several risk-factors, early signs and symptoms of BC are known, the knowledge and awareness of this disease remains poor among the population. The present study aimed to determine the extent of knowledge and awareness of BC, its risk factors, early signs and symptoms and breast self-examination (BSE) practice as an early detection method among Indian college-going female students.Design/methodology/approachThe authors conducted a cross-sectional survey at a University in Delhi-NCR. Data on socio-demographic, knowledge and awareness of BC including BSE was collected using a pretested questionnaire. Chi-square test and logistic regression analysis was performed. All tests were two-sided and significance was set at p < 0.05.FindingsA total of 866 female students participated in the study with mean age of 22.32 (±0.146) years having mean body mass index (BMI) of 21.22 (±3.52). As high as 82.1% of the participants had heard of BC but while 74.8% thought early detection is possible, 70.7% believed BC cannot be prevented. Gene mutations (60.2%) were identified as a significant risk factor, while breast pain (61.4%) was commonly recognized as a sign of BC. Only 29.8% of students ever performed BSE. Increased odds of performing BSE (OR = 3.4) was found among students who recognized gene mutations as an important BC risk factor.Research limitations/implicationsKnowledge and awareness of BC including BSE among female college students were found to be below average. It is suggested that there is an urgent need for increasing BC awareness among young girls through workshops and mobile-health interventions.Practical implicationsThis study provides new information on the level of knowledge and awareness of BC risk factors, sign and symptoms and self-examination practice among young college girls. Moreover, this study advocates the need for design and implementation of a sustainable digital health model for active population BC screening, which is not being done currently.Social implicationsBC is a highly aggressive disease, which is now one of the leading causes of morbidity and mortality in India and world over. Although the knowledge of BC risk factors and its signs and symptoms have increased, the awareness of these elements among the general population at large is low and/or missing, especially in India. Furthermore, as a consequence of unorganized screening programs in the country, majority of women are presenting young with locally advanced disease. Understanding the existing level of knowledge and educating school, college and University students of the pertinent factors and screening practices such as BSE could drastically help in improving the self-screening and/or clinical examination rates. This could potentially lead to early detection and improved prognosis, thus ameliorating disease burden.Originality/valueThis study is one of the few studies conducted in India among young female college students belonging to non-medical backgrounds, delineating the level of knowledge and awareness of BC risk factors and signs and symptoms along with practice of early detection method such as BSE. The study has a considerable sample size and provides valuable evidence for a need to implement programs incorporating digital health models for accelerating awareness and screening of young girls in both rural and urban settings.

Abstract
Follicular lymphoma (FL) originates from germinal center B cells, is the most prevalent form of indolent non-Hodgkin's lymphoma. Upfront management is based on stage, grade, and disease burden. Radiotherapy may be curative in limited disease while chemoimmunotherapy is preferred in advanced disease. Maintenance therapy is routinely administered but its role is debatable. Relapses are common and interval from initial therapy to relapse is most important prognostic factor for relapsed FL. Management of relapsed patients is based on the initial management, the interval from prior therapies, and the toxicity of available therapies. Multiple agents are available for patients after two or more lines of therapy, but sequencing remains poorly defined.

Abstract
Background The spectrum and significance of Variants of Uncertain Significance (VUS) mutations in breast cancer predisposition genes is poorly defined in the Indian population. Methods All new female breast cancer patients from 1 March 2019 to 28 February 2020 were screened. Those providing informed consent and without previous genetic testing were recruited. Multigene panel testing (107 genes) by next-generation sequencing was performed for all patients. Descriptive statistics was used to describe the spectrum of VUS mutations. Results Out of 236 patients recruited in the study, a VUS was detected in 89 patients (37.71%). VUS pathogenic ratio was 2.02. A total of 121 different VUS mutations in 40 different genes were detected. Fourteen patients (15.7%) had a VUS in high penetrance genes and 36 VUS mutations (29.8%) were detected in one of the genes involved in homologous recombination repair pathway. No therapeutic interventions were done based on VUS. Conclusions In this large prospective study of genetic determinants of breast cancer from India, a high prevalence of VUS (37.71%) was detected with 15.7% patients having a VUS in high penetrance genes. More evidence needs to be generated from larger multicentric studies to better understand the implications of these genetic variants and enable their reclassification.

Abstract
An excessive amount of fat deposition in the body leads to obesity which is a complex disease and poses a generic threat to human health. It increases the risk of various other diseases like diabetes, cardiovascular disease, and multiple types of cancer. Genomic studies have shown that the expression of the fat mass obesity (FTO) gene was highly altered and identified as one of the key biomarkers for obesity. This study has been undertaken to investigate the mutational profile of the FTO gene and elucidates its effect on the protein structure and function. Harmful effects of various missense mutations were predicted using different independent tools and it was observed that all mutations were highly pathogenic. Molecular dynamics (MD) simulations were performed to study the structure and function of FTO protein upon different mutations and it was found that mutations decreased the structure stability and affected protein conformation. Furthermore, a protein residue network analysis suggested that the mutations affected the overall residues bonding and topology. Finally, molecular docking coupled with MD simulation suggested that mutations affected FTO substrate binding by changing the protein-ligand affinity. Hence, the results of this finding would help in an in-depth understanding of the molecular biology of the FTO gene and its variants and lead to the development of effective therapeutics against associated diseases and disorders.

Abstract
BACKGROUND The expression pattern of common antigens including cytoplasmic kappa/lambda ratio (cyKLR) was evaluated by flow cytometric immunophenotyping (FCMI) to explore their relevance in discriminating normal and aberrant plasma cells (NPC and APC, respectively) across spectrum of plasma cell proliferative disorders (PCPD). METHODS In this prospective analysis, 791 samples from PCPD (treatment naive = 455; partially treated = 336) were evaluated for expression of CD38, CD138, CD45, CD19, CD56, CD27, CD81, CD117, Cy-kappa, and Cy-lambda using FCMI. RESULTS Amongst the entire cohort, 20.7% (n = 164) samples displayed only APC, 21% (n = 165) only NPC and 58% (n = 462) showed coexistence of NPC and APC. Using pattern-based recognition (PBR) for three common patterns (CD19 vs. CD56; CD27 vs. CD56 and CD19 vs. CD27), APC was separable from NPC in 93% samples. In 6.5% samples, the gating markers contributed in APC-NPC differentiation and in the remaining 0.5% CD117 and CD81 proved useful. Clonality assessment was found to be crucial to label plasma cell compartment as completely normal or aberrant in 42% cases with either all NPC or all APC. Sixty one out of 462 cases (13%) revealed cyKLR within normal reference range and in these cases; abnormal cyKLR was demonstrable only after gating APC separately based on PBR. CONCLUSION Fair discrimination between NPC and APC is achievable in all PCPD samples using eight markers (Gating: CD38, CD138, CD45; PBR:CD19, CD56, CD27; clonality: Cy-kappa and Cy-lambda). Thus, combined assessment of clonality and immunophenotypic aberrancies is required for accurate, reliable and precise assessment of NPC and APC compartments in PCPD.

Abstract
T-follicular helper cells (TFH) are a unique subset of T-cells with varied transcriptional profiles and functions. In the last 2016 WHO classification, lymphomas arising from TFH were included as a broad category and emphasis was given to separating them from other peripheral T cell lymphomas. The neoplasms derived from these mainly comprise angioimmunoblastic T-cell lymphoma, peripheral T-cell lymphoma with T-follicular helper cell phenotype, follicular T-cell lymphoma, and cutaneous CD4+ small-medium sized lymphoproliferative disorders. The TFH lymphomas comprise both indolent and aggressive forms. Additional immunohistochemistry to identify TFH cells like CD10, BCL6, ICOS, PD1, CXCL13 and mutations like RHOA, IDH2 is required for diagnosis and prognostication. The understanding of these has evolved over the years, and currently we review the updates and pathobiology of the above.

Abstract
BACKGROUND Phthalates are known endocrine-disrupting chemicals used indiscriminately as constituents in consumer products including food processing, and packaging, cosmetics, personal care and household items. Although, few studies have assessed the risk of breast cancer on exposure to phthalates, their association with breast cancer risk in Indian women have not yet been evaluated. METHODS We conducted a case-control study involving 171 participants. Urinary concentrations of six phthalate dieters; DMP (Dimethyl phthalate), DEP (Diethyl phthalate), DBP (Dibutyl phthalate), BBP (benzyl butyl phthalate), DEHP (Di-2-ethyl-hexyl phthalate), DINOP (Di-n-octyl phthalate) were estimated by GC-MS and geometric means were calculated. Univariate and multivariable logistic regression was performed to assess breast cancer risk on exposure to phthalates. Genes responsive to phthalates were identified through literature search and matched with NGS data, and gene-enrichment analysis was performed. RESULTS Significant associations were observed between urinary phthalate concentrations and increased risk of breast cancer for di-butyl phthalate (OR=1.5, 95% CI; 1.06, 2.11, p = 0.002) and di-2-ethyl-hexyl phthalate (>median vs ≤ median; OR=2.97, 95% CI; 1.18, 7.47, p = 0.005) in multivariable analyses. We also found several phthalate-responsive gene mutations in paired breast tumor tissues, which include PTPRD (76.19%), AR (42.86%), CYP1A1 (42.86%), CYP19A1 (23.81%), AHRR (19.05%), PIK3CA (19.05%), CYP1B1 (9.52%), RB1 (9.52%) and MMP9 (9.52%). Gene-enrichment analysis revealed that these genes form a major part of ER/PR, PPAR and HIF-1α-TGF-β signaling cascades involved in breast cancer CONCLUSION: Although the sample size is small, in this first case-control study from India, DBP and DEHP were found to be associated with increased risk of invasive breast cancer and tumor tissues revealed mutations in several phthalate-responsive genes. It is, therefore suggested that human biomonitoring in India and larger studies evaluating the early life genetic and epigenetic alterations on phthalates exposure are required to establish their role in breast carcinogenesis.

Abstract
e12594 Background: Dose-dense adjuvant chemotherapy has been shown to be associated with improved long-term survival outcomes in triple-negative breast cancer (TNBC). However, there is a lacuna of data on the benefits of dose-dense neo-adjuvant chemotherapy (NACT) in TNBC particularly with respect to pathological complete response (pCR) rates and with the relapse or overall survival. To our knowledge no studies have been reported regarding the use or benefit of dose-dense NACT (ddNACT) over conventional NACT (cNACT) among Indian women with TNBC. Methods: This retrospective study included, 217 newly diagnosed cases of TNBC, treated with sequential anthracycline and taxane based NACT followed by definitive surgery. Study groups consisted of 137 patients who received 3-weekly conventional chemotherapy (cNACT group) and 80 patients with 2-weekly dose-dense NACT (ddNACT group) with granulocyte-colony-stimulating factor (GCSF) prophylaxis. Primary endpoint of the study was pathological complete response (pCR) rate and secondary endpoints were relapse-free survival (RFS), overall survival (OS) and grade-3/4 chemotoxicities. Fisher’s exact test was used to compare pCR rates. Kaplan-Meier and cox regression survival analysis were used to compare survival outcomes. Results: Median age (Interquartile range) in overall population, cNACT and ddNACT group were 43 (37-50), 44 (37-50) and 42 (36.5-48) years respectively. Baseline parameters were comparable between study groups, except that ddNACT group had higher proportion of premenopausal patients as compared to cNACT group (72.5% vs 55.5%). Majority of the patients presented at advanced stage, with stage-III being predominant, constituted by 97 (70.1%) and 55 (67.5%) patients in cNACT and ddNACT group respectively. No significant difference in pCR rate (32.8% vs 31.3%; p=0.808) was observed across the study groups. In multivariate analysis, dose-dense chemotherapy was no better than conventional chemotherapy for achieving pCR (Odds ratio [OR]: 0.86, 95% confidence interval [CI]: 0.45-1.63; p=0.639 and had no RFS advantage over conventional chemotherapy [Median RFS: Not reached in ddNACT vs 56.1 months in cNACT; Hazard Ratio: 0.83, 95% CI (0.48-1.44)]. OS was also comparable in both the groups with 3-year survival rate of 78.8% (95%CI: 60.9-89.2) in ddNACT group vs 84.3% (95% CI: 74.8-90.4) in cNACT group. Grade-3/4 toxicities were comparable in both groups. Conclusions: This observational study focusing on ddNACT among TNBC patients demonstrated similar pCR and toxicity rates with no significant survival benefits compared to cNACT regimen. Cost-benefits of frequent hospital visits for GCSF administration associated with dose dense therapy need further consideration before implementing such these regimens in lower-middle income countries.

Abstract
e24081 Background: Assessment of physical and psychological symptoms using patient-reported outcome (PRO) scales is an often overlooked aspect in oncological practice in resource constrained settings. We assessed the pattern of symptoms at diagnosis in solid organ cancers using an innovative smart device based delivery of the Edmonton Symptom Assessment Scale (ESAS). Methods: We assessed PROs using ESAS at diagnosis in adult patients diagnosed with solid organ cancers at a large tertiary care centre in New Delhi, India from September 2021 to January 2022. The ESAS was delivered to patient's smart phone as a text message that provided a unique link to complete the questionnaire in Hindi or English, as preferred by the patient. Symptom severity was categorized into physical, psychological, and total symptom domains and the scores were further classified as none to mild (0-3) or moderate to severe (4-10). Univariate and Multivariate logistic regression analyses were performed to determine predictive factors. Results: Text message with ESAS completion link was sent to 653 consecutive patients, of whom 509 (77.9%) completed the questionnaire during the study period. The median age was 52 years and 53.2 % were males. The primary cancer site was lung, breast, gastrointestinal, and others in 27.7%, 28.1%, 14.4%, and 29.8%, respectively. Pain (59.1%) and tiredness (57.8%) constituted the maximum physical symptom scores in moderate and severe category. Patients with lung cancer had most physical symptoms categorised in moderate and severe compared with other cancers (P = 0.03), while psychological symptoms were more likely to be moderate to severe females (P = 0.01). In the multivariable logistic regression analysis after adjusting for measured confounders, primary cancer site (lung vs others) and sex (female vs male) were significant predictors for moderate and severe physical and psychological symptoms, respectively. Conclusions: A simple mobile-based ESAS delivery system can help in collecting PRO data to assess symptom burden in patients diagnosed with cancer. The symptom burden assessment can aid in providing personalised symptom-directed measures to improve the quality of life of patients with cancer.

Abstract
e19585 Background: Ibrutinib, an oral Bruton's tyrosine kinase inhibitor, is approved for the treatment of chronic lymphocytic leukemia (CLL) in both upfront and relapsed/refractory. The prevalence of CLL is very low in India compared to western countries. Hence, the real-world data regarding efficacy and safety of Ibrutinib among the Indian population is very scarce. In this study, we aim to examine the toxicity profile, treatment response, and survival outcomes among Indian patients with CLL treated with Ibrutinib. Methods: In this retrospective study, we recruited all consecutive patients diagnosed with CLL, both treatment naïve (TN) and relapsed/refractory (R/R) CLL, on Ibrutinib (daily dose of 420 mg), registered at the Department of Medical Oncology, All India Institute of Medical Sciences, New Delhi, India between April 2016 and December 2021. Diagnosis of CLL, an indication of treatment, and response assessment were based on the recent guidelines (2018) from the International Workshop on CLL (iwCLL). Results: A total of 90 patients were recruited in this study, of which 33 were newly diagnosed and 57 had R/R CLL. Median age of the cohort was 60 years (range, 35–80 years) and male to female ratio was 3:1. The median total leukocyte count was 55x109/L and Del 17p was detected in 18% of cases. The R/R cases had received a median of 1(1-3) prior line of therapy. Overall response rate was observed in 76(84.4%), complete response was in 18 (20%) cases, partial response (PR) was in 49 (54.4%) cases, and in 9 (10%) cases PR with lymphocytosis (PR-L) was observed. With a median follow-up period of 15 months (4-60), 2-year progression-free survival (PFS) was 80% for the whole cohort. The median PFS was not reached in TN cases and was 18 months in R/R cases. Grade-3/4 adverse events (A/E) were seen in 17 (29.8%, n = 57) of R/R cases and in 3 (9.1%,n = 33) of TN cases. The most common Grade-3/4 A/E were infections in 19 (21.1%), (Varicella: 7, Pneumocystis: 6, Aspergilosis: 2, Mucormycosis: 1, Disseminated tuberculosis: 1, Encephalitis: 1, Others: 1) and cytopenias in 9 (10%) of cases. Other A/E were fatigue in 6 cases, arthralgia in 3, bleeding in 2, cutaneous rash in 2, reactivation of hepatitis-B in 2, diarrhea in 2, arrhythmia in 2, and autoimmune hemolytic anemia in one case. Ten patients (11.1%) had a dose reduction due to AE. The discontinuation rate was 27 (30%), due to progressive disease in 18 patients and due to adverse events in 9 patients. Twenty patients died, 14 due to disease progression or Richter's transformation, 5 due to infections, and 2 due to other reasons. Conclusions: This is the largest study of ibrutinib from India. Ibrutinib is safe and effective in upfront and R/R cases of CLL. Infections are the most common adverse event in R/R cases. Acyclovir and Co-trimoxazole prophylaxis can be considered in R/R cases of CLL in routine clinical practice . Arrhythmias were rare A/E as compared with the available literature.

Abstract
e12593 Background: Capecitabine maintenance has demonstrated a survival benefit in triple-negative breast cancer (TNBC) patients not achieving pathological complete response (pCR) following neo-adjuvant chemotherapy (NACT). However, there is scarcity of data from Indian sub-continent corroborating the benefit of capecitabine maintenance. Methods: This retrospective study comprised of 161 TNBC patients registered at our institute between a period of May 2013 to Dec 2020, who received NACT (sequential anthracycline and taxane) but did not achieve pCR. Capecitabine was added to the institutional protocol since 2017 for maintenance therapy of TNBC patients who didn’t achieve pCR post NACT. Using Kaplan-Meir survival analysis and multivariate cox-proportional hazard models, we analysed differences in the relapse-free survival (RFS) and overall survival (OS) among those who received capecitabine maintenance therapy (n=80) versus those who did not receive it (n=81). Results: Distribution of age, family history, baseline performance score, tumor size, node positivity and clinical stage at time of presentation were comparable between the study groups, except for menopausal status (50% in control vs 33% in capecitabine group). Median(IQR) follow up time was 22.2 (16.2-27.4) months in capecitabine groups vs 19.3 (11.7-35.1) in control group. Twenty-three (28.8%) women in the capecitabine group had a disease-relapse while 45.7% (n=37) had relapsed in control group (p=0.026). Median RFS was 20.4 (17.8-25.9) months in control group while it was not reached in capecitabine group (log rank p=0.007). Adjusted for other baseline clinical characteristics, hazard of disease-relapse was significantly lower in the capecitabine group compared to controls [adjusted Hazard Ratio (aHR), 95% CI: 0.57 (0.34-0.96), p=0.035]. Median OS was not achieved in both the study groups, however, the hazard of death was lower in capecitabine group compared to control [aHR(95%CI): 0.44 (0.20-1.01), p-0.053]. Stratified by menopausal status, effect of capecitabine maintenance on disease relapse and RFS was only significant among the post-menopausal women [aHR (95%CI): 0.24 (0.10-0.59)]. Conclusions: This is the first study from our country, demonstrating a survival benefit with capecitabine maintenance in patients with TNBC not achieving pCR following NACT, particularly in post-menopausal women. It is an important observation as most of our patients present with locally advanced disease where pCR rate is low.

Abstract
e12601 Background: Neoadjuvant chemotherapy (NACT) with HER2 blockade is preferred approach for treatment of early and locally advanced HER2 positive breast cancer. However, there is a lack of survival data with respect to pathological complete response (pCR) from India. Methods: We retrospectively evaluated 211 HER2 positive female breast cancer patients registered between years 2014 and 2021, who received three different NACT regimens (i) Anthracycline free TCH (n=116) [docetaxel (75mg/m2), carboplatin (AUC = 6) and trastuzumab (8mg/kg loading followed by 6mg/kg) with G-CSF q 21 days], (ii) EC-TH (n=52) [epirubicin (90 mg/m2) and cyclophosphamide (600 mg/m2) for 4 cycles followed by 4 cycles of docetaxel (85mg/m2)] and (iii) EC-T (n=43, without trastuzumab due to financial constraints). Primary end point was pCR. Secondary end points were disease free survival (DFS), Overall Survival (OS) and safety profile. Results: Median age was 45 years (24-71), 88 (41.7%) were postmenopausal and 104 (49.3%) were ER/PR positive. Twenty-two (10.4%) patients were stage II, 164 (77.7.%) were stage III and 25 (11.9%) were oligometastatic stage IV. Distribution of age, performance status, tumor size and nodal positivity were comparable across the study groups. Pathological CR in trastuzumab containing groups, was higher compared to non-trastuzumab containing group (35.8% vs 20%, p=0.045) and was similar between, TCH and EC-TH groups. Median follow-up was 32.9 months (5.7-108), 3-year DFS and OS were 54.8% and 92.1% respectively. Pathological CR rates and survival outcomes of the three groups are given in table 1. When stratified by pCR status, in the trastuzumab containing groups, achievement of pCR translated to improved DFS (log rank p=0.01). This survival advantage of pCR was not seen in non-trastuzumab containing group. The outcome of trastuzumab containing both regimens were similar. Grade 3/4 toxicities were recorded in 21.6% of TCH, 26.7% of EC-TH and in 25.2% of EC-T groups. Most common toxicities were anemia (16.3%), thrombocytopenia (14.2%) and vomiting (10.2%). Conclusions: Trastuzumab containing regimens impact pCR rates and in turn the survival outcomes among Indian women with HER2 positive breast cancer. Safety and efficacy of anthracycline free TCH regimen is comparable with EC-TH.[Table: see text]

Abstract
Objective: To evaluate the role of shear wave elastography (SWE) of suspicious axillary lymph nodes and its combination with B-mode USG in predicting nodal metastasis in breast cancer patients. Methods: Prospective observational study was performed from June 2018 to August 2020 on breast cancer patients with suspicious axillary nodes on USG. B-mode features (cortical thickness, effacement of fatty hilum, non-hilar blood flow and round shape) and SWE parameters (Emax, Emin, Emean and ESD) of the node with the thickest cortex were evaluated. Diagnostic performances of USG, SWE and their combination were estimated using pathological status of the node on biopsy as the gold standard. Results: Of the 54 patients evaluated, optimal elasticity maps were obtained in 49 nodes of 49 patients (mean age, 46.3 ± 12.1 years; 48/49 (98%) females). On biopsy, 38 nodes (77.6%) had metastasis, while 11 (22.4%) had reactive hyperplasia. Emax, Emin, Emean and ESD of both cortex and hilum were significantly higher in metastatic than reactive nodes. Emax (cortex) ≥14.9 kPa had the best diagnostic performance (sensitivity, 73.7%; specificity, 81.8%). Cortical thickness ≥6.7 mm had the best diagnostic performance among B-mode features (sensitivity, 89.5%; specificity, 72.7%). Combining cortical thickness with effacement of fatty hilum and/or non-hilar blood flow yielded sensitivity of 89.5% and specificity of 90.9%. Addition of Emax (cortex) to cortical thickness and combination of ≥2 B-mode features increased their specificities to 90.9 and 100%, respectively. Conclusions: Metastatic axillary nodes are stiffer than reactive nodes on SWE in breast cancer patients. Emax (cortex) has the best diagnostic performance in differentiating between reactive hyperplasia and nodal metastasis. Combination of Emax (cortex) and cortical thickness increases the specificity for diagnosing metastasis, especially in nodes showing only cortical thickening. Advances in knowledge: Combination of SWE and B-mode USG is highly specific for differentiating metastasis from reactive hyperplasia in suspicious nodes of breast carcinoma patients, especially in nodes with only cortical thickening.

Abstract
e12505 Background: In HER2 positive breast cancer, TCH is a safe and efficacious anthracycline free regimen used as both adjuvant and neoadjuvant modality. Three is scarcity of data regarding its long term safety and efficacy from India. Methods: This retrospective study comprised of 210HER2 positive breast cancer female patients treated with TCH [docetaxel (75mg/m2), carboplatin (AUC=6) and trastuzumab (8mg/kg loading followed by 6mg/kg) q 21 days with GSF prophylaxis] protocol for 6 cycles at our centre between Jan 2014 and Dec 2021. All eligible patients received maintenance trastuzumab, hormonal therapy and radiotherapy as per institutional protocol. The information regarding baseline clinico-demographic characteristics, treatment details, outcomes and toxicities were collected and evaluated. Results: The median age was 49 years (23-72), 113 (53.8%) were post-menopausal and 100 (47.6%) were Estrogen receptor/Progesterone receptor positive. Sixty-eight (32.4%) patients were stage I and II, 112 (53.3%) stage III and 30 (14.3%) were oligometastatic. TCH regimen was given as neoadjuvant chemotherapy (NACT) in 130 (61.9%) patients and as adjuvant chemotherapy in 80 (38.1%) patients. Of the patients receiving NACT, 114 (87.6%) patients underwent surgery. Twenty-two (19.3%) patients underwent breast conservation surgery and 92 (80.7%) underwent modified radical mastectomy. Over the study period, 62 (29.5%) patients had progression of the disease and 22 (10.5%) patients died. With a median follow up of 31.9 months, 3-year disease free survival (DFS) was 63.5% and overall survival (OS) was 90.8%. Median DFS was 31 months in patients with node positive disease and was not reached in patients with node positive disease. Of the patients who received NACT, pathologic complete response (pCR) was recorded in 42 (36.8%) patients. Three-year DFS was 59.1% in patients who achieved pCR and 44.8% in those who did not achieve pCR. Any grade 3/4 toxicity was seen in 26.7% patients which caused dose modification in 13.9% patients. The most common grade 3/4 hematological toxicity was anemia (15.1%) and thrombocytopenia (10.4%), while non-hematological toxicity was diarrhea (11.6%). Febrile neutropenia was seen in 4 (1.9%) patients. Four patients (1.9%) had reversible decrease in cardiac left ventricular ejection fraction. Conclusions: Anthracycline free TCH regimen is an effective and safe regimen for use in curative (adjuvant and neoadjuvant) setting for HER2 positive breast cancer in Indian women with outcomes comparable to the anthracycline based regimens reported in literature.

Abstract
e13008 Background: Ado-trastuzumab emtansine (T-DM1) is the standard of care for patients with advanced HER2 positive breast cancer (BC) patients who progress on the first line anti-HER2 therapy or relapse within 6 months of adjuvant trastuzumab. There is a lack of data regarding the safety and efficacy of T-DM1 in the Indian population. Methods: This retrospective study aims to evaluate the efficacy and toxicity of T-DM1 in advanced HER2 positive female BC patients, registered at All India Institute of Medical Sciences, (AIIMS) New Delhi, India, between the years 2015-2021. The response was evaluated by Response evaluated Criteria in Solid Tumors(RECIST 1.1)guidelines. Progression-free survival (PFS) was calculated from the beginning of treatment with T-DM1 until disease progression or death from any cause. Overall survival (OS) was calculated from the beginning of treatment with T-DM1 until death from any cause. Results: This study included eighty patients with a median age of 49 years (27-73). Forty-four (55%) were premenopausal and hormone receptor positivity (either ER or PR) was found in 36 (45%) cases. The ECOG performance status was 0-1in 80% of patients. De- novo metastatic disease was found in 38(47.5%) cases whereas the remaining 42 (52.5%) patients were diagnosed with early or locally advanced disease and later become metastatic. The sites of metastasis were lungs in 26 (32.5%), brain in 23 (28.7%) liver in 23 (28.7%), bones in 18 patients (22.5%), lymph nodes in 15(18.7%), cutaneous and other rare sites in 8(10%) cases. All patients had received trastuzumab in the prior line of treatment and 18 (22.5%) patients had also received pertuzumab along with trastuzumab. The median number of T-DM1 cycles given was 9 (range 3-35). The overall response rate was 80%, 8(10%) achieved a complete response, 36 (45%) had a partial response, and 12 (15%) patients had stable disease. The Grade 3/4 toxicities were observed in 20(25%) cases and these were: thrombocytopenia 16 (20%), fatigue 10 (12.5%), transaminitis 10(12.5%), anemia 2 (2.5%), and peripheral neuropathy in 2 (2.5%) cases. Dose delay, interruption, and modification were observed in 25 (31.2%) cases. Within the median follow-up period of 18 months, the median PFS was 10 months and OS was 27 months. Hormone status (ER/PR) and prior pertuzumab therapy did not influence the outcome. Conclusions: This is the first study from the Indian subcontinent on T-DM1. It is safe and effective in our population and has shown comparable outcomes with the available literature however, higher rates of thrombocytopenia were observed.

Abstract
e12549 Background: Prevalence of Triple Negative Breast Cancer (TNBC), which has utterly poor prognosis and higher recurrence rate, is high among Indian women ranging from 20-43% across different regions of India. Previous studies from other countries have shown that pretreatment hemoglobin and hematocrit values influence treatment outcomes among breast cancer patients. Recent 2019-2020 National Family Health Survey (NFHS) of India reported that 66.4% of women suffer from anemia. This study examined the association of pre-treatment hemoglobin levels with survival outcomes among Indian women with TNBC. Methods: We retrospectively analyzed the medical records of 435 women registered at our institute with a diagnosis of TNBC between the years 2013-2021. Pre-treatment hemoglobin levels i.e. either before the start of neoadjuvant chemotherapy (NACT) or prior to surgery among those who received adjuvant chemotherapy were retrieved from the medical records along with clinical and tumor characteristics. Primary outcomes were relapse free survival (RFS) and overall survivals (OS). Cox-regression and Kaplan-Meier survival analysis were used to examine the association of pre-treatment anemia with survival outcomes in these patients. Results: Fifty-one percent (n=221) of the 435 TNBC patients in our study cohort had pretreatment hemoglobin level of <12.0 g/dL (based on the World Health Organization criteria). 278 patients received NACT and pathological complete response (pCR) rates were similar in anemic (31.5%) and non-anemic groups (30.1%). When adjusted for clinical and other hematological parameters, anemia was not associated with pCR. Median follow-up of the study cohort was 22.9 months (Range: 2.6 to 92.7 months). Pre-treatment anemia was significantly associated with poor RFS when adjusted for clinical and hematological parameters [adjusted Hazard ratio (aHR) (95%CI): 1.53 (1.02-2.31)]. Median RFS was 52.5 months among the anemic group and was not reached in non-anemic group. Effect of anemia on RFS did not vary by age category or menopausal status. However, the effect of anemia on OS varied significantly by menopausal status. Menopausal women with anemia at time of diagnosis had significantly higher hazard of death compared to menopausal women without anemia [aHR (95%CI): 5.0 (1.15-21.66)] and this association was not observed in pre-menopausal women [aHR (95%CI): 0.53 (0.19-1.44)]. Conclusions: Pretreatment hemoglobin level of <12g/dL was associated with poor survival outcomes among Indian women with TNBC and the effect of anemia on overall survival of these patients varied by menopausal status. Evaluation of hemoglobin levels during chemotherapy, pre-post surgery, and at various stages of follow-up is needed to determine the independent association of hemoglobin level trajectories with treatment outcomes and long-term survival among these TNBC patients.

Abstract
INTRODUCTION Diffuse large B-cell lymphoma (DLBCL) is the most prevalent subtype of non-Hodgkin's lymphoma (NHL) accounting for 30% of adult NHL worldwide and 50% in developing countries like India. DNA damage and Myc-induced transformation are well-known contributing factors towards development of DLBCL. A recently identified HSP90 co-chaperone complex R2TP has been shown to contribute towards DNA damage and Myc-induced transformation. This study aimed to analyse the immunohistochemical (IHC) expression of R2TP complex components RUVBL1, PIH1D1, and RPAP3 in DLBCL patients and correlate with prognosis. METHODS DLBCL (n = 54) histological slides were retrieved from archives, and detailed histomorphological and clinical features were noted. IHC staining of R2TP complex components RUVBL1, PIH1D1, and RPAP3 was performed on 54 cases (FFPE) of DLBCL. Expression data were correlated with survival and clinical features. RESULTS Out of the 54 DLBCL cases, 59.26% (n = 32) stained positive for RUVBL1. The RUVBL1 expression was associated with poor prognosis in both progression-free survival (PFS) (p = 0.0146) and overall survival (OS) (p = 0.0328). The expression was positively correlated with bone marrow involvement (p = 0.0525). The expression of PIH1D1 was observed in 68.51% (n = 32) of DLBCL cases, and positive correlation was observed with international prognostic index score (p = 0.0246); however, no correlation was observed with PFS or OS. Finally, RPAP3 was found immunopositive in only 1 case of DLBCL. CONCLUSIONS Immunopositivity for RUVBL1 is associated with poor prognosis along with a higher relapse rate amongst the DLBCL patients. PIH1D1 immunopositivity correlated with a higher IPI score.

Abstract
Introduction Hand-foot syndrome (HFS) is a common cutaneous side effect of capecitabine therapy. Apart from oral cyclooxygenase-2 (COX-2) inhibitor (celecoxib), there are no proven strategies for the prevention of HFS. However, celecoxib is associated with significant cardiotoxicity. To date, no study has evaluated the role of topical COX inhibitor, diclofenac. In this study, we aim to compare topical 1% diclofenac gel with placebo in the prevention of capecitabine-induced HFS. Methods This is a randomized, placebo-controlled, double-blind, parallel-group superiority trial: the Diclofenac Topical in Reducing Capecitabine induced HFS (D-TORCH) study. A total of 264 patients with breast and gastrointestinal malignancies will be randomly allocated (stratified by sex and type of therapy [monotherapy or combination regimen with capecitabine]) to receive either 1% topical diclofenac or placebo that will be applied over the palmar and dorsal surface of the hands twice daily whilst taking capecitabine for 12 weeks. The patients will be followed up until the end of four cycles. The primary objective of this study is to compare the effect of topical diclofenac with placebo in preventing HFS (incidence of NCI CTCAEv5.0 grade 2 or higher HFS). The secondary objective is to compare the effect of topical diclofenac with placebo on preventing all grades of HFS (incidence of NCI CTCv5.0 all grade HFS), time to develop HFS (from the start of capecitabine), patient-reported outcomes (PROs) (HF-HRQoL questionnaire), adherence with the application (self-reported), capecitabine dose changes (number of patients with dose modifications due to HFS) and safety profile (NCICTCv5.0 all grade HFS) Discussion The D-TORCH study aims to determine if 1% topical diclofenac reduces the incidence of grade 2 or higher HFS in patients receiving capecitabine. To date, there have been a lot of trials for hand-foot syndrome prevention using agents like pyridoxine, vitamin E, carvedilol, and various polyherbal formulations, but none has been found successful. If the trial meets the primary end point, 1% topical diclofenac will be the new standard of care for HFS prevention. Trial registration Clinical Trials Registry of India CTRI/2021/01/030592. Prospectively registered on January 19, 2021

Abstract
Treatment of patients with resistant/refractory multiple myeloma (MM) is an unmet need. In this phase II study, we evaluated the role of bendamustine, pomalidomide and dexamethasone combination in this setting. Between February 2020 and December 2021, 28 patients were recruited. Patients received bendamustine 120 mg/m2 day 1, pomalidomide 3 mg days 1-21, and dexamethasone 40 mg days 1, 8, 11, 22, regimen given for a maximum of six cycles. The median (range) age of the patients was 54 (30-76) years and 15 (53.6%) were males. Patients had received a median (range) of three (two-six) prior lines and 85.7% were refractory to both lenalidomide and bortezomib. The primary end-point was the overall response rate (ORR) defined as ≥partial response after at least three cycles. Secondary objectives were toxicity, progression-free survival (PFS), time to progression and overall survival (OS). An intent-to-treat analysis was done. An ORR of 57.6% was achieved. Patients with extramedullary myeloma had a better response rate. At a median follow-up of 8.6 months, the median PFS and OS were 6.2 and 9.7 months respectively. Toxicity was manageable; mainly haematological (neutropenia, 46.4%; anaemia, 42.8%; and thrombocytopenia, 7.1%). Bendamustine, pomalidomide and dexamethasone could be a novel combination for the heavily pretreated, lenalidomide-refractory myeloma population.

Abstract
BACKGROUND Immunophenotypic profile and post-therapy alteration in antigenic expression were evaluated in normal, reactive, and aberrant plasma cells (NPC, RPC, and APC) for impact on measurable residual disease (MRD) assessment in multiple myeloma (MM). METHODS Samples from non-MM staging marrow (n = 30), Hodgkin's lymphoma (n = 30) and MM (n = 724) were prospectively evaluated for expression profiles of NPC, RPC, and APC using antigens recommended in consensus guidelines. RESULTS Polyclonal NPC-RPC demonstrated aberrations for all antigens evaluated with a higher frequency of aberrancies in post-therapy samples compared to treatment naïve samples (p < 0.001%). Immunomodulation in APC was observed in 79% of post-therapy samples with a change in expression of 1, 2, and ≥3 antigens in 19.9%, 15.6%, and 43.5% samples, respectively. In 13.4% of samples, APC showed no aberrancy and aberrant status was assigned based on cytoplasmic light chain restriction (cyLCR) alone. 9% samples with an admixture of NPC and APC displayed normal cytoplasmic kappa to lambda ratio (cyKLR) when the percentage of APC of total PC (neoplastic plasma cell index, NPCI), was below 25% and 50% for kappa and lambda restricted cases, respectively. CONCLUSION The panorama and high frequency of antigenic aberrations on polyclonal PC signify the importance of MRD assay validation on a large cohort under normal and reactive conditions. Frequent Immunophenotypic shifts in APC re-confirm the redundancy of baseline immunophenotype for MRD evaluation. Small clones of APC may be missed by assessment of cyKLR alone and therefore, surface marker aberrancy supported by cyLCR is required for definitive assignment of residual APC.
