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: Multiparameter flow cytometry is increasingly being used in determining DNA content in several hematological malignancies where abnormal DNA ploidy is a useful prognostic marker. This study was done to analyze the DNA ploidy of plasma cells in multiple myeloma (MM) by flow cytometry and explore its role as a prognostic factor. Material and Methods: Propidium-iodide staining technique and gating based on light scatter properties were used. DNA index (DI) of the tumor sample was calculated as the ratio of the DNA content of the G0-G1 population of the myeloma cells with the normal control cells (lymphocytes) present in the same sample. Based on DI, ploidy was categorized as diploidy, hypodiploidy, and hyperdiploidy and the results were correlated with the clinical outcome. Results: Among 32 patients, none had hypodiploid DNA content, 8 (25%) patients had hyperdiploid DNA, and 24 (75%) patients had diploid DNA. There was no significant association between DI and international staging system staging (P = 0.68), Eastern Cooperative Oncology Group Performance Status (P = 0.59), and post-induction remission status (P = 0.10). The median overall survival (OS) in the study patients was 20 (CI 11.4–28.8) months and the median progression-free survival was not reached. There was no difference in the OS among patients with diploid MM and hyperdiploid MM (P = 0.84). Conclusion: Although hyperdiploid MM has been reported to have a better prognosis than diploid MM, we did not find any significant difference possibly due to the small sample size. Nevertheless, flow cytometry is a useful tool in DNA ploidy analysis and its role as a prognostic factor in various hematologic malignancies including MM can be further explored.

miRNAs are known to be aberrantly expressed in the serum, tissue, and Peripheral Blood Mononuclear Cells (PBMC) of cancer patients and could serve as potential noninvasive diagnostic markers for breast cancer. The aim of this study was to identify the differentially expressed miRNA using next-generation sequencing (NGS) from the paired PBMC samples from breast cancer patients and age-matched healthy individuals and explore their functional significance.In this study, PBMCs were employed for the detection of miRNAs by NGS in locally advanced breast cancer (LABC) women of South Indian origin who were divided into three age groups, (a) 40yrs-50yrs (b) 50yrs-60yrs and (c) 60yrs-70yrs, compared with age-matched control groups.Four miRNAs (hsa-miR-192-5p, hsa-miR-24-2-2p, hsa-miR-3609, and hsa-miR-664b-3p) were found to be differentially expressed among LABC patients compared with age matched healthy women of the South Indian population. While miR-24-2-5p, miR3609, and miR-664b-3p were down-regulated, miR-192-5p was up-regulated. Gene Ontology (GO) annotations implicated miRNA with signaling pathways in peripheral nerve synapses, glutamatergic synapse, and cell morphogenesis, all of which play a pivotal role in the manifestation of cancer.Four miRNAs- 3 (While miR-24-2-5p, miR3609, and miR-664b-3p) downregulated and one upregulated (miR-192-5p) were identified as potential biomarkers for patients with locally advanced breast cancer. These markers could be validated in studies with a larger sample size.

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.

Survival of children with acute lymphoblastic leukemia (ALL) has improved from 10% to 90% over the last six decades. Survival gains in adult ALL have been more modest and confined to the adolescent and young adult population. Age is an important factor in determining outcomes in ALL. Additional factors like adverse biology, less intense treatment regimens, and poorer tolerance to therapy contribute to inferior survival among adults. Indian physicians face unique challenges while managing these patients. These are high infection rates, limited access to high-end investigations, and newer drugs. In this context, the management decisions in an individual patient are highly nuanced. Through a case-based review, we discuss representative scenarios in adult ALL where we detail our current approach to treatment in the context of available evidence.

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.

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.

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).

Background and objective Delays in the management of osteosarcoma (OGS) lead to tumor progression and the development of metastasis, resulting in a decrease in overall survival (OS). The primary objective of this study was to determine whether delays occur in implementing the individual steps in the management of OGS in South India. Methods In this study, core biopsy reports between October 2019 and October 2021 were retrospectively examined for a diagnosis of OGS. The primary outcome variables in this study were time to MRI, time to biopsy, time to biopsy report, time to neoadjuvant chemotherapy (NACT), time to surgery, and time to adjuvant chemotherapy (ACT). Statistical analysis was performed by comparing the outcome variables with the hypothesized mean. Results There were 38 patients with primary non-metastatic OGS. Of these, 92% received NACT, and 74% completed full treatment. The mean time to MRI was 11.3 ± 6.7 days, mean time to NACT was 15.3 ± 12.7 days, mean time to surgery was 31.1 ± 15.3 days, and mean time to ACT was 29.7 ± 10.1 days. Time to MRI was more than seven days in 68% of the cases, while time to NACT was more than seven days in 74%. Time to surgery was more than 21 days in 83% of the cases, and time to ACT was more than 21 days in 82% of the cases. Conclusion Based on our findings, there is a significant delay (p0.05) in time to MRI, time to NACT, time to surgery, and time to ACT. The delay in time to surgery is more than the delay in time to MRI, time to NACT, and time to ACT. The delay is due to a variety of reasons, the most common being the long waiting period at the hospital.

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: 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.

Yolk sac tumor is a malignant germ cell tumor, which typically occurs in the gonads with elevated serum alpha-fetoprotein (AFP). Among extragonadal sites, the liver is an uncommon location for primary pediatric yolk sac tumors. Other common hepatic tumors in this age group presenting with elevated serum AFP like hepatoblastoma and hepatocellular carcinoma must be differentiated from yolk sac tumors for initiating appropriate treatment and accurate prognostication. Lung metastasis with refractoriness to chemotherapy is an extraordinary presentation that has never been documented in the literature. We report our experience with a 2-year-old female child initially misdiagnosed as hepatoblastoma. It was found that LIN28 positivity by immunohistochemistry aided in confirmation of the histopathological diagnosis of primary yolk sac tumor of the liver.

PURPOSE Published experience with autologous stem-cell transplantation (ASCT) in non-Hodgkin lymphoma (NHL) from the Indian subcontinent is extremely limited. Here, we describe the activity and outcomes of this treatment modality at a large tertiary care center in India. PATIENTS AND METHODS We retrospectively analyzed adult patients with NHL who were eligible for ASCT and autografted between January 1, 2002, and December 15, 2020, at our transplant unit. Toxicities, complications, and long-term outcomes were compared between patients who underwent transplant during 2002-2012 (group A) and 2013-2020 (group B). RESULTS Overall, 80 patients (group A, n = 37; group B, n = 43) underwent ASCT using peripheral blood stem cells. At a median follow-up of 57.6 months, the 5-year event-free survival (EFS) and overall survival (OS) were 43.5% and 47.6%, respectively, for all patients. More recently (group B), patients had reduced 100-day transplant-related mortality (2.3% v 21.6%, P < .01), improved 3-year EFS (52.9% v 37.3%, P = .04), and superior OS (at 3-year; 63.4% v 43.2%, P = .02). Patients in group B also tolerated the procedure better, with improved resource utilization. In multivariate analysis, an International Prognostic Index (IPI) ≥ 3 at diagnosis adversely affected EFS (hazard ratio [HR] = 2.82, P = .009) and OS (HR = 2.84, P = .01) after ASCT. Low pretransplant serum albumin levels were associated with inferior EFS (HR = 2.68, P = .02) and transplant-related mortality (odds ratio = 10.80, P = .02) after ASCT. CONCLUSION It is feasible to achieve comparable short- and long-term outcomes in patients with NHL undergoing ASCT in a resource-poor country with improved supportive care and expertise of the transplant team and center.

Cytomegalovirus (CMV) retinitis is one of the common complications in profoundly immunosuppressed patients such as those with acquired immune deficiency syndrome. It has been rarely reported in patients with lymphoma on aggressive chemotherapy. We encountered a patient with bilateral CMV retinitis who developed this vision-threatening complication while on low-dose palliative metronomic chemotherapy with oral drugs (cyclophosphamide, procarbazine, etoposide, and prednisolone). Though the infection resolved with treatment, there was residual vision loss. This case is presented to sensitize clinicians to the possibility of unusual infections in patients on long-term oral chemotherapies.

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.

Genetic factors could be attributed to the variability in docetaxel plasma levels and its subsequent therapeutic response. The objectives of this study were to assess the effect of ABCB1 gene polymorphisms [SNPs rs1045642 (C3435T) and rs1128503 (C1236T)] on docetaxel plasma levels and also to analyze the influence of docetaxel plasma levels on tumour response in the ethnically distinct South Indian population. 104 locally advanced breast cancer (LABC) patients on docetaxel-based neo‐adjuvant chemotherapy (NACT) were included. The plasma docetaxel levels were estimated using the validated reverse phase liquid chromatography with mass spectrometry (LC–MS/MS). DNA was extracted (phenol‐chloroform extraction method) and the real‐time PCR system using validated TaqMan® SNP genotyping assay method was used for genotyping. Tumour response was assessed by RECIST criteria based on the MRI images. Patients with “CT/TT” genotype of the SNP C1236T had a C0/Ct ratio of 1.6 times higher than those with “CC” genotype (13.5 ± 6.5 vs 8.3 ± 3.1, p = 0.002). Though not significant, patients with “CT/TT” genotype had greater initial plasma concentration (C0) and area under the plasma concentration–time curve (AUC0−t). Conversely, the SNP C3435T was not associated with the plasma docetaxel levels. Furthermore, the C0 and normalized C0 were found to be higher in tumour responders compared to non-responders (p

Diffuse large B cell lymphoma (DLBCLs) constitute 40% of all non-Hodgkin lymphoma and it represent a heterogeneous group of neoplasms rather than a single clinicopathological entity. We analysed the outcomes and clinical features based on the cell of origin in a series of patients with DLBCL from our institute. Medical case records of all newly diagnosed DLBCL treated in our institute from January 2015 to July 2017 were analysed for this study. Cell of origin classification was based on immunohistochemistry using Hans algorithm. Kaplan–Meier curves were used to determine survival. Ninety-five patients were diagnosed to have DLBCL subtype. Immunophenotypic subtyping was available for 71 patients. The median age at diagnosis was 56 years with no difference between Germinal centre B cell (GCB) and non-Germinal centre B cell (non-GCB) subtypes. Approximately 44% of patients had extra-nodal disease, stomach being the commonest site. Forty percent of patients had stage III/IV disease. Bulky disease and extra-nodal presentation was predominantly seen with non-GCB subtype (46% vs 20% and 36% vs 29% respectively). Rituximab was used in 75% of the patients with DLBCL. The 2-year disease-free survival was 70% versus 53% (p = 0.38) in GCB versus non-GCB subtype. This is one of the few data on DLBCL patients reported from India which has described outcomes based on the cell of origin. The disease-free survival in our country appears to be superior in GCB subtype which needs to be confirmed in a larger subset of patients.

Aim Triple negative subtype (TNBC) is an aggressive breast cancer with inferior survival. Pathological CR (pCR) is a good surrogate endpoint for survival among patients receiving neoadjuvant chemotherapy (NACT). We attempted to validate the composite score(CPS) (Jaccqueline et al, J Clin Oncol 26:246-252) combining clinical and pathological variables among TNBC patients receiving NACT at our center. Methodology Data of patients with TNBC who underwent NACT between January 2014 to July 2017 was retrospectively analysed. The composite CPS score included cTN stage and y pTN stage, and ranged from 0 to 4. This was calculated using an online software (http://www3.mdanderson.org/app/medcalc/index.cfm?pagename=bcnt). The scores obtained from the calculator was used to develop a risk grouping into low risk (0,1) and High risk (2,3,4). Overall survival (OS)and disease free survival (DFS) were calculated using the Kaplan-Meier method and differences was examined using the log rank test. Results Seventy-eight patients with TNBC [median age: 45 (24-75)] had received NACT (anthracyclines and taxanes). Early and locally advanced breast cancer constituted 17 (21.8 %) and 61 (78.2%) respectively and 22 (28.2 %) achieved pCR. After a median follow up of 28 months (5-62), 3-yr DFS and OS were 59% and 82% respectively for the entire population. The 3-yr DFS in low (n=18) and high risk (n=60) patients was 85.7% and 51.4% respectively (p=0.032). The 3-yr OS in the low and high risk was 93% and 79% respectively(p=0.28, NS). Conclusion Our study supports the use of the composite clinical pathological score (CPS) as a prognostic marker in patients with non-metastatic triple negative breast cancer. The risk stratification developed may help identify patients who may require additional adjuvant therapy.

Background In autologous stem cell transplant (ASCT) for lymphomas, no standard conditioning regimen has been defined so far. Thus, the choice is guided by the center's familiarity and experience with a particular regimen. Objective To determine the response, toxicity, and survival outcomes in lymphoma patients who underwent ASCT with CBV (cyclophosphamide, carmustine, and etoposide) conditioning regimen. Materials and Methods Between January 2013 and May 2019, 45 consecutive lymphoma patients who had ASCT with CBV conditioning regimen were included in this retrospective study. CBV consisted of cyclophosphamide (1.5 g/m2/day × 4 days), carmustine (300 mg/m2 × 1 day), and etoposide (125 mg/m2 twice daily × 3 days). Baseline characteristics, pre transplant response, apheresis, post-transplant toxicities, post-transplant response, and survival outcomes were collected. Endpoints were toxicity, response, event-free survival (EFS), and overall survival (OS). Results The median age was 30 (range: 6–64) years. Diagnosis was Hodgkin lymphoma (HL) in 26 (58%) and non-Hodgkin lymphoma (NHL) in 19 (42%). Forty-three patients (95%) had chemosensitive disease; 22(49%) in CR, and 21 (46%) in PR. The median CD34 was 2.95 × 106/kg (range: 0.9–9.56). The median time to neutrophil engraftment was 11 days (9–23) and 13 (8–36) days for platelets. All patients had febrile neutropenia, clinically and/or microbiologically documented infection was seen in 75% of patients. The most common grade 3/4 toxicities were mucositis (n = 4, 9%), diarrhea (n = 4, 9%), and nausea/vomiting (n = 2, 4%). The average days of hospitalization was 18 (range: 10–37). Day 100 mortality was 6.6% (n = 3). The median follow-up was 44.8 months. The median EFS for the entire cohort was 23.8 months; for HL, the median EFS was not reached, and for NHL, it was 7.97 months (95% confidence interval [CI]: 1.57–14.37). The median OS for the entire cohort and for HL was not reached; for NHL, it was 24.3 months (95% CI: 0.56–48.11). Conclusion CBV conditioning regimen was well tolerated with low grade 3/4 toxicities and efficacy comparable to literature data.

Introduction: The role of aspirin in cancer prevention has been well defined; the last decade revealed its therapeutic role with Giampieri et al. (2016) showed improved efficacy with aspirin added to capecitabine in heavily pre-treated metastatic colorectal cancer. Aspirin affects tumour growth through the PI3K pathway, which regulates apoptosis and autophagy. The objective of our study was to compare the efficacy of Aspirin plus EOX chemotherapy versus EOX alone in locally advanced and metastatic gastric cancer. Methods: All patients with advanced gastric cancer reporting to the Department of Medical oncology between March 2017 to May 2019 were screened for study eligibility. They were randomly assigned to standard EOX with or without aspirin at a daily dose of 150 mg. Tumor measurements were assessed at baseline and 3-4 cycles by an independent blinded radiologist according to RECIST criteria 1.1. Toxicity profiles were recorded as per CTCAE v 4.03. Per protocol group was identified as 70 patients. The primary endpoint was overall response rates in the per-protocol group defined as patients who received a minimum of 3 cycles and had an evaluable response after randomization. The secondary endpoints included toxicity analysis, Progression-free survival, and Overall survival.Results: Ninety-five patients who fulfilled the study inclusion and exclusion criteria were randomized to group1 EOX (50) or group 2 EOX plus Aspirin(45). Seventy patients were included for the per-protocol analysis. The overall response rate in group1 was 27% compared to group2, which was 42%, P=0.176. The median duration of follow was 29 (18.56-39.45) months. The median overall survival (n=95) of group 1 versus group 2 was 11 (8.58-13.42) months and 10 (6.86-13.14) months, respectively, P=0.90. There was no statistical significance in the overall survival per-protocol analysis (n=70) between group one 12(8.75-15.25) months versus group two 12(6.21-17.79)months, P= 0.50. Conclusions: There was no improvement in the response rates, progression-free survival, and overall survival on adding Aspirin to EOX chemotherapy in locally advanced and metastatic gastric cancer in an unselected population. A further role of PI3K mutation as a biomarker needs to be evaluated in this setting.

In this study, the role of change in tumor stiffness between pre- and post-two cycles of neoadjuvant chemotherapy (NACT) measured by Acoustic Radiation Force Impulse (ARFI) imaging for predicting the response to NACT in breast cancer was analyzed.Fifty-two adult women with biopsy-proven locally advanced breast cancer and early-stage breast cancer who received NACT followed by either modified radical mastectomy or breast conservation surgery were included in the study. Tumor stiffness represented by shear wave velocity (SWV) in meter per second by ARFI imaging was measured before and after two cycles of NACT. Participants were categorized into responders and nonresponders based on pathological response assessment from the postoperative specimen. The association of change in tumor stiffness between pre- and post-two cycles of NACT with final pathological response status was assessed.The mean change in SWV before and after completion of two cycles of NACT was 0.42 ± 0.16 and 0.17 ± 0.11 m/s in responders and nonresponders, respectively, and this difference was proven to be statistically significant (p 0.001) suggesting that tumors that exhibit a larger reduction in tumor stiffness, respond better. An SWV reduction cut-off of 0.295 m/s between baseline and post-two cycles of NACT was also arrived at, which can discriminate between responders and nonresponders with a sensitivity and specificity of 88% and 83%, respectively.Difference in tumor stiffness measured by ARFI imaging before and after two cycles of chemotherapy can be used as a reliable early predictor of response to chemotherapy in breast cancer.

462 Background: TCGA and ACRG have classified gastric cancer (GC) into molecular subgroups using genomics. We attempted to classify GC from our region using IHC (Immunohistochemistry) to understand its prognostic significance and compare with similar data from other parts of the world. Methods: This was a retrospective cohort of GC patients from years 2017-18. EBV (LMP), MSI (MLH1, MSH2, PMS2, MSH6),p53, E-cadherin and PIK3CA were assessed by IHC. Clinicopathological characteristics and survival were evaluated for association with molecular subtypes as defined by TCGA and ACRG classification system. Results: A total of 191patients were included with EBV positivity 35 (18.3 %), MSI 33(17.3 %), p-53 aberration 25(13.1%), E-cadherin negative (29.3%). On univariate analysis, p53 aberration was associated with higher age (>60 yrs), E- cadherin negative with diffuse histology & antro-pyloric region as predominant site. MSI with intestinal histology & antro-pyloric region as predominant site with MSI. The TCGA classification revealed EBV 35 (18%), MSI 28 (15 % ), GS 48 (25 %) and CIN 80 (42% ) subtypes respectively. CIN subtype was seen predominantly above 40 yrs of age (P=0.04), GS subtype was frequently associated with diffuse histology P

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.

The covid-19 pandemic has impacted the management of non-covid-19 illnesses. Epithelial ovarian cancer (EOC) requires long-duration multidisciplinary treatment. Teleconsultation and shared care are suggested solutions to mitigate the consequences of the pandemic. However, these may be challenging to implement among patients who come from the lower economic strata. We report the disastrous impact of the pandemic on the care of EOC by comparing patients who were treated during the pandemic with those treated in the previous year. We collected the following data from newly diagnosed patients with EOC: time from diagnosis to treatment, time for completion of planned chemotherapy, and proportion of patients completing various components of therapy (surgery and chemotherapy). Patients treated between January 2019 and September 2019 (Group 1: Pre-covid) were compared with those treated between January 2020 and December 2020 (Group 2: During covid pandemic). A total of 82 patients were registered [Group 1: 43(51%) Group 2: 39(49)]. The median time from diagnosis to start of treatment was longer in group 2 when compared to group 1 [31(23–58) days versus 17(11–30) days (p = 0.03)]. The proportion of patients who had surgery in group 2 was lower in comparison to group 1 [33(77%) versus 21(54%) (p = 0.02)]. Proportion of patients who underwent neoadjuvant (NACT) and surgery were fewer in group 2 in comparison to group 1 [9(33%) versus 18(64%) p = 0.002]. Among patients planned for adjuvant chemotherapy, the median time from diagnosis to treatment was longer in group 2 [28(17–45) days, group 1 versus 49(26–78) days, group 2 (p = 0.04)]. The treatment of patients with EOC was adversely impacted due to the COVID-19 pandemic. There was a compromise in the proportion of patients completing planned therapy. Even among those who completed the treatment, there were considerable delays when compared with the pre-covid period. The impact of these compromises on the outcomes will be known with longer follow-up.

OBJECTIVES Epithelial ovarian cancer is one of the commonest gynecologic cancers and one with the highest mortality. This retrospective cohort study was done to identify predictors of outcomes in platinum-sensitive relapsed ovarian cancer patients (PS-ROC). METHODS Data regarding baseline characters, laboratory findings, therapeutic details and survival outcomes was obtained from the medical records of PS-ROC patients presented between January 2015 and December 2019. Prognostic score was constructed using factors which were significant on multivariate analysis to predict survival outcomes. RESULTS A total of 71 (PS-ROC) patients were included in the study with a median age of 50 years. Relapse treatment was either chemotherapy alone (n=53, 75%) or chemotherapy plus surgery (n=18, 25%). The estimated progression-free survival (PFS) and overall survival were 10 and 29 months, respectively. The overall response rate after treatment of relapse was 59%. Prognostic score was created with the 3 factors (each scoring 1 point) which were predictive of PFS (higher lymphocyte-monocyte ratio, longer platinum-free interval and secondary cytoreduction). Patients with low score (0,1) had better PFS than those with higher score (2,3) (13 vs. 7 mo [P=0.0001]). CONCLUSIONS A composite prognostic score could predict outcomes in PS-ROC and potentially identify a subgroup with very poor prognosis. Future studies with a greater number of patients are needed to validate these findings. This information could help tailor more intense therapies to the high-risk patients and attempt to improve outcomes and serve as stratification factors for prospective trials.

Purpose: To study the late toxicities of treatment and its impact on Breast cancer survivors among Indian patients. Materials and Methods: Our study recruited 152 curatively treated non metastatic carcinoma breast patients. The baseline demographic details, disease related and treatment related information were collected. The late effects included breast cancer related lymphedema, shoulder dysfunction, treatment induced bone loss, hypothyroidism, cardiac dysfunction, and chemotherapy induced cognitive dysfunction and Quality of life. Results: The median age was 47 years (range 27 -72 years). The cumulative frequency of BCRL and shoulder dysfunction was 31.57% and 34.86% respectively. The improvement in BCRL with corrective intervention was not statistically significant. The BCRL was significantly associated with shoulder dysfunction. The frequency of loss of bone mineral density was 38.15%. There was statistically significant improvement in bone mineral density with interventions. The cumulative rate of hypothyroidism and cardiac dysfunction was 14.47 % and 2.17% respectively which improved after corrective therapy. We did not find any delayed cognitive dysfunction. There was improvement in global health, physical function, role function, fatigue, Nausea, vomiting, pain scores, insomnia, Loss of appetite, diarrhea and arm symptoms over time with intervention. Conclusion: Our study has shown that nearly half of the survivors were suffering from at least one of the late effects. The intervention helped in improving the loss of bone mineral density, hypothyroidism, cardiac dysfunction and quality of life in Breast cancer survivors.

Anemia is a common finding and important cause of morbidity in patients with acute lymphoblastic leukemia (ALL) at diagnosis or during the course of its protracted treatment. We studied profile of anemia in ALL patients on maintenance therapy and evaluated specific micronutrients as cause of this anemia.ALL patients who were on maintenance therapy and had grade ≥ 2 anemia were recruited for the study. Serum iron studies, folate, and vitamin B12 were done to identify micronutrient deficiency and to initiate supplementation with specific components if found to be deficient. Toxicities, improvement of anemia, micronutrient levels, and disease outcome were studied after 3 months.From March 2015 to September 2016, 105 ALL patients were found to be on maintenance fulfilling the inclusion criteria. Overall, the proportion of anemia was 80%(N = 84). Majority had normocytic normochromic anemia (71%). Macrocytic anemia was seen in 18% and microcytic hypochromic in 9.5%. In patients with anemia of grade ≥ 2 (N = 84), 38 patients (45%) had biochemical deficiency of serum folate, and 7 (8%) had vitamin B12 deficiency. No biochemical evidence of iron deficiency was found. Supplementation of deficient micronutrients improved anemia: mean hemoglobin significantly increased from 8.06 ± 1.63 to 10.78 ± 1.53 (p 0.001) at 3 months; and reduced treatment toxicities, mean number of febrile neutropenia episodes (p = 0.007), and treatment interruptions of 2 weeks (p = 0.002) were lowered. Patients with anemia had significantly more relapses (N = 14,64%) compared to patients without anemia (N = 8,36%), (p = 0.040).Timely identification and correction of micronutrient deficiencies causing anemia in ALL patients on maintenance can enhance treatment outcomes.

Introduction Ovarian cancer is the third most common cancer and the second most common cause of death among gynecological cancers in Indian women. Ovarian cancer is heterogeneous, among them, epithelial ovarian cancer (EOC) is the most common. Primary cytoreductive surgery along with six to eight cycles of a combination of platinum and taxanes chemotherapy is the cornerstone of first-line treatment in EOC. This study was done to find clinicopathological factors affecting survival outcomes with first-line therapy in EOC in a real-world setting. Objectives This study was aimed to find factors affecting progression-free survival (PFS) and overall survival (OS) with first-line treatment in EOC. Materials and Methods We conducted a single-center retrospective study. We screened all the patients diagnosed with ovarian cancer from January 2015 till December 2019. We locked data in August 2019. Eligible patients were histologically confirmed EOC who underwent primary cytoreduction or received more than or equal to two cycles of chemotherapy or both. Patients who had received first-line treatment at another hospital were excluded. Results Patients demographics and clinical characteristics: between January 5, 2015 to August 31, 2019, 435 patients with a diagnosis of ovarian malignancy were registered at our center. Among them, 406 (82%) had EOC, 290 (64%) newly diagnosed, and fulfilling eligibility criteria were included in the final analysis. The median age of the cohort was 53 years (range: 21–89 years) and 157 patients (54%) were >50 years of age (the Eastern Oncology Cooperative Group Performance status was ≥ 2 in 124 patients [43%]; median duration of symptoms was 3 months; and stage III/IV: 240 [83%]). Grading of the tumor was available in 240 patients of which 219 (91%) were of high grade. Subtyping was available in 272 patients (94%) of which the serous subtype was the most common constituting 228 patients (79%).Treatment Most patients received chemotherapy (n = 283 [98%]) as the first modality of treatment (neoadjuvant/adjuvant and palliative). As neoadjuvant (NACT) in 130 patients (45%) and as adjuvant following surgery in 81 patients (29%). The most common chemotherapy regimen was a combination of carboplatin and paclitaxel in 256 patients (88%). Among 290 patients 218 (75%) underwent cytoreductive surgery. Among them, optimal cytoreduction was achieved in 108 patients (52%). Optimal cytoreduction rate (OCR) with upfront surgery and after NACT was 44 and 53%, respectively (Chi-square test: 0.86; p = 0.35).Survival The median follow-up of the study was 17 months (range: 10–28 months) and it was 20 months (range: 12–35 months) for patients who were alive. At last, follow-up, 149 patients (51%) had progressed and 109 (38%) died. The estimated median PFS and OS were 19 months (95% CI: 16.1–21.0) and 39 months (95% CI: 29.0–48.8), respectively. On multivariate analysis, primary surgery (HR: 0.1, 95% CI: 0.06–0.21; p-value: Conclusion Primary surgery (upfront or interval) was associated with improved survival. Newer agents like bevacizumab, poly-ADP (adenosine diphosphate)-ribose polymerase inhibitors and HIPEC should be incorporated precisely into first line of therapy to improve outcomes.

Extraosseous Ewing's Sarcoma (EES) is a high grade rare malignancy from Ewing's family tumors (EFTs) occurring in soft tissues. Diagnosis of EES relies on a constellation of features, including round cell morphology, characteristic immunohistochemistry (such as CD99, FLI-1 and NKX2.2 positivity), and pathognomic molecular abnormalities of t(11;22)(q24;q12). Multimodality treatment has improved the prognosis and clinical outcome in EFTs. Due to its rarity, the current recommendation to treat EES is based on Skeletal Ewing's Sarcoma (SES) guidelines. However, achieving clear surgical margins in the Head and Neck region is often challenging due to complex anatomy and close proximity to critical structures, placing patients at risk of loco-regional recurrence in the absence of adjuvant therapy. The literature on head and neck EES is scarce, consisting of a few retrospective case series and case reports. Herein, we describe the characteristic clinico-pathological features and treatment of three EES patients with primaries from Parotid, Nasal cavity/ Nasopharynx and Oropharynx, with a comprehensive review of the literature. Keywords: Ewing's Family of tumors, Extraosseous Ewing's sarcoma of head and neck.

Hematopoietic stem-cell transplantation (HSCT) is a life-saving procedure often performed to cure relapsed and difficult-to-treat malignancies. Only a handful of centers in India were initially involved in the delivery of these services. However, in the last decade, more than 100 centers in the private and public domain have started offering transplant services in the country. Moreover, there are funding options, which has opened up this expensive treatment options for economically backward patients. Costs apart, there are multiple social, familial, and emotional challenges faced by these patients. A multidisciplinary support team involving social workers, psychologists, and transplant nurses, besides the treating hematologist/oncologist, is required for the optimum care of these patients. These challenges, in the Indian context, are often unique. Unfortunately, there is limited information and resource available to guide counseling of patients planned for HSCT in India. We conducted a workshop at our center where a panel of experts with experience in dealing with patients undergoing HSCT discussed issues faced by them. These discussions constitute a valuable resource for counseling patients planned for HSCT. They were transcribed by a postgraduate doctor and are summarised here in a case-based format.

Context: Blast phase (BP) remains a significant challenge in the treatment of chronic myeloid leukemia (CML). Currently, allogeneic stem cell transplant (AlloSCT) remains the best chance of cure for BP, with 3-year survival ranging from 35–40%. Outcomes of AlloSCT are better when performed in the second chronic phase. Objective: There is limited contemporary data of AlloSCT in CML-BP from resource-limited settings. We hereby present our experience of AlloSCT in patients with CML-BP Design: Retrospective study of CML-BP patients who underwent AlloSCT between October 2017 to July 2019. Median follow-up was 24 months. Setting: Tertiary institution with developing transplant unit. Patients or Other Participants: Seven CML-BP (WHO criteria) patients underwent AlloSCT at our center after reverting to chronic phase. Interventions: All patients received myeloablative conditioning and stem cells harvested from peripheral blood. Main Outcomes Measures: Leukemia-free survival (LFS) was defined as the time from the AlloSCT to relapse or death due to any cause. Overall survival (OS) was the time from AlloSCT to death due to any cause. Results: The median age was 40 years (range, 9–52), and the male-to-female ratio was 5:2. Four patients had de novo BP; the subtype of BP was lymphoid in three, myeloid in three, and mixed phenotypic (B/myeloid) in one. The median time from the diagnosis to ASCT was 6 (3–12) months. The median CD34+ dose was 7.6 (range, 6.6–8.9) x106 cells/kg. Peri-transplant toxicities within the first 100 days included febrile neutropenia with septic shock in three, cytomegalovirus (CMV) reactivation in three, ≥ grade 3 mucositis in two patients, secondary graft failure (SGF) in one, and poor graft function (PGF) in one. In both patients who had a haploidentical donor transplant, one had SGF and one had PGF. Day 100 transplant-related mortality (TRM) was observed in two patients, disseminated infections being the cause of death for both. Post-AlloSCT, all living patients received dasatinib maintenance starting at a median of 50 (47–60) days. On the last follow-up on April 30, 2021, two-year PFS and OS were 43% and 57%, respectively. Conclusions: AlloSCT can result in promising survival for carefully selected patients of CML-BP, especially with a matched sibling donor. The adverse outcome for both the haplo-transplant patients underscores the need for careful donor selection and reflects the initial learning curve. None of the authors have any relevant conflicts of interest to declare.

Breast cancer (BC) is one of the most common malignancies worldwide. Although the burden and mechanisms of endocrine therapy-related bone loss are known, the evidence is scanty regarding the impact of cytotoxic chemotherapy on bone health. We have attempted to summarize the effect of cytotoxic chemotherapy on bone health in BC patients. A comprehensive literature search was performed via MEDLINE and Cochrane library databases to evaluate the effect of chemotherapy on bone health among women with BC. We included articles related to skeletal-related events, bone mineral density, bone turnover markers, osteoporosis-specific quality of life, bisphosphonate, and other bone-directed therapy. We excluded articles that included patients with metastatic breast cancer and patients receiving hormonal therapy. Bone microenvironment in cancer is directly or indirectly influenced by clinical, hormonal, nutritional, and treatment factors. Calcitonin, parathyroid hormone, calcitriol, and estrogen are the major hormonal regulators. Bone turnover markers, namely bone formation and resorption markers, have been used to predict bone loss, fracture risk, and monitoring treatment response. Chemotherapeutic drugs such as anthracyclines and taxanes synergistically affect BMD and quality of life. Calcium, vitamin D, bisphosphonates, and denosumab are supplemented to prevent excess bone resorption. Bone-targeted anti-resorptive agents have been studied as potential anticancer agents in the adjuvant treatment of breast cancer. This review summarizes the negative effect of chemotherapy on bone health of BC patients and the importance of preventing or treating bone loss.
