RESUMEN

INTRODUCTION: A significant proportion of breast cancer cases are hereditary and are potentially preventable. However, adoption of the preventive measures remains a significant challenge, particularly because of to lack of knowledge and awareness in low- to middle-income countries. METHODS: This prospective study conducted at a high-volume tertiary care cancer center in North India to assess the knowledge, awareness, and attitudes of female breast cancer patients and impact of a brief educational intervention. The study involved three phases: pre-interventional assessment, educational intervention, and post-interventional assessment utilizing a structured questionnaire. RESULTS: The study involved 300 newly diagnosed breast cancer patients; 16.7% were familial. At the outset, 87.0% patients had low knowledge of risk factors, 90.3% about screening, and 32.7% about treatment. Awareness levels were low: 13.7% aware of familial risk and 2.7% of breast cancer genes. Affordability of genetic testing was low (15.2%), and interest in testing for self and family members was limited (32.0% and 26.3%). Following educational intervention, a significant positive percentage change was noticed in knowledge (risk factors: 12.8%, screening: 36.2%, treatment: 82%), awareness (familial risk: 66.7%, BRCA gene: 12.3%), and attitude (testing for self: 17.8%, family: 19.5%). CONCLUSIONS: This study highlights the significant knowledge gaps among breast cancer patients regarding genetics. The educational intervention led to notable improvements in knowledge, awareness, and attitudes, underscoring the importance of tailored patient education in breast cancer care.

RESUMEN

Nasopharyngeal carcinoma (NPC) is often diagnosed at a very advanced stage due to its location and non-specific initial symptoms. Moreover, no clinically useful serological marker has been established so far for early detection of NPC. In this study, we have investigated the clinical significance of plasma Epstein-Barr virus DNA load along with interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) levels to evaluate if these three all together can be useful as a strong serological marker for early detection and prediction of treatment response in patients with NPC. Plasma EBV DNA load, IL-6 level, VEGF expressions were measured in 24 patients with NPC at presentation and various time points during and after treatment. There was a positive correlation between high plasma EBV DNA load with higher IL-6 and VEGF expression, which was closely associated with therapeutic response as well. Persistent or recurrent plasma EBV load with higher IL-6 and VEGF levels can potentially predict disease progression and may be useful to select patients for additional therapy and longer follow-up.

RESUMEN

BACKGROUND: Primary mediastinal GCT (PMGCT) is a rare entity and comprises 10-15% of all mediastinal tumors. We present our institutional experience of MGCT treated with multimodality management. MATERIALS AND METHODS: We conducted a retrospective analysis between 2010 to 2020 of all mediastinal germ cell tumors registered at our center. Data on patient demographics, treatments received, treatment toxicities and response were recorded. Overall survival and relapse free survival were estimated using Kaplan-Meier methods. RESULTS: A total of 30 patients were identified. The median age was 25.5 (range, 18-45) years. Common presenting features included cough (70%) and shortness of breath (70%). Histology wise, 60% patients were non seminomatous histology, whereas 33.3% patients were Seminoma. Twenty-seven (90%) patients received chemotherapy as the first-line treatment, of whom five patients (16.6%) underwent surgery and radiation therapy subsequently. Median follow-up was 26.9 months. Thirteen patients (43.3%) had complete response (43.3%) and eight patients had partial response (26.7%), while three patients (5.5%) had progressive disease. Three-year relapse-free survival rate was 69.6% (95% confidence interval [CI], 42.8-85.6%). Overall survival (OS) at 3 years was 73.4% (95% CI, 49.4-87.3%). Patients with seminoma had a 3 year OS of 90.0% (95% CI, 47.3-98.5%) compared to those with non-seminoma (63.53% [95% CI, 32.3-83.3%]). CONCLUSIONS: Multiagent chemotherapy is the backbone of treatment in PMGCT. Seminomatous PMGCT have excellent prognosis, while further improvement is needed in those with nonseminomatous tumor.

RESUMEN

INTRODUCTION: Nasopharyngeal carcinoma (NPC) is a rare malignancy in India except in north-eastern states. We present our institutional experience of 16 years highlighting management, outcomes, responses and toxicities. MATERIALS AND METHODS: NPC patients registered at our center during the period of 2000-2015. The primary objective of the study was to assess the overall survival (OS). Secondary outcome included determinations of response rates, progression free survival (PFS) and to assess treatment-related toxicity (CTCAE v4.0). Institute ethics committee approval was obtained prior to initiation of this study. RESULTS: Data was retrieved from complete records of 222 patients out of 390 registered during study period. There were 163 males (73.4%) and 59 females (26.6%) with a male to female ratio of 2.8:1. The median age was 35 years (range 6-73). Only 5.6% (n = 12) presented in early-stage disease (stage I and II) while 89.6% (n = 199) were advanced stage (stage III, IVA, IVB). Five patients (2.2%) presented as metastatic disease. Majority of patients were treated with induction chemotherapy followed by concurrent chemoradiation (CCRT) {76.1%, n = 169}. Relapses were documented in 10.4% patients. 5% patients had loco-regional relapse while distant metastases were seen in 4% patients. The 3-year PFS and OS rates are 60.9% and 68.4%, respectively. Achieving a CR predicted superior OS on multivariate analysis. CONCLUSIONS: NPC is a rare malignancy and majority presented with advanced stages. This data outlines our experience and outcomes with a predominantly induction chemotherapy followed by definitive CCRT based approach.

RESUMEN

Nasopharyngeal carcinoma (NPC) is the most common malignant tumor of the nasopharynx. Although NPC is not endemic in India, higher incidences were observed in its North-Eastern regions particularly Sikkim, Nagaland, Manipur, and Mizoram. Early detection of NPC is difficult because the nasopharynx is not readily amenable to clinical examination and symptoms of NPC are nonspecific. The development of suitable biomarkers for early diagnosis of NPC as well as accurate monitoring of treatment response is needed urgently. In this exploratory pilot study, we have investigated the clinical significance of assessing plasma Epstein-Barr virus (EBV) DNA load at diagnosis and during treatment. We found that EBV DNA is detectable at diagnosis in the majority of patients with nonendemic NPC and the absolute copy number of circulating EBV DNA per milliliter increases progressively with the stage of the disease. The viral load declined significantly with induction chemotherapy and definitive chemoradiation but showed a sharp rise at relapse. Patients with EBV DNA levels ≥1500 copies/ml had a higher risk of disease progression or relapse when compared with patients who had EBV DNA <1500 copies/ml at baseline. Estimation of plasma EBV DNA may serve as an excellent noninvasive tool to monitor disease extent, response to therapy, and for better prediction of future relapse or progression-free survival in a nonendemic NPC patient population.

RESUMEN

For the young breast cancer population in India, the burden of hereditary breast cancer is not well defined. Moreover, genetic testing criteria (National Comprehensive Cancer Network and Mainstreaming Cancer Genetics (MCG) plus) have never been validated for the Indian population. Therefore, this study tested 236 consecutive breast cancer patients for germline pathogenic mutations using next-generation sequencing and reflex Multiplex Ligation Probe Amplification (MLPA). The findings showed a high prevalence of pathogenic/likely pathogenic (P/LP) mutations (18.64%), with 34% mutations in non BRCA genes. The sensitivity of the testing criteria was inadequate (88.6% for NCCN and 86.36% for MCG plus criteria), reiterating the need to expand the criteria. The uptake of cascade testing was low (10% of eligible previvors), highlighting this as an area of unmet need. Multicentric studies to validate these data and provide further insight into the hereditary cancer burden in India are the need of the hour.

RESUMEN

BACKGROUND: The burden of hereditary breast cancer in India is not well defined. Moreover, genetic testing criteria (National Comprehensive Cancer Network [NCCN] and Mainstreaming Cancer Genetics [MCG] Plus) have never been validated in the Indian population. METHODS: All new female breast cancer patients from 1st March 2019 to 28th 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. The frequency of pathogenic/likely pathogenic (P/LP) mutations between patients qualifying and not qualifying the testing criteria was compared and their sensitivity was computed. RESULTS: Overall, 275 breast cancer patients were screened and 236 patients were included (median age 45 years); 30 patients did not consent and 9 patients previously underwent genetic testing. Thirty-four (14%) women had a positive family history and 35% had triple-negative breast cancer. P/LP mutations were found in 44/236 (18.64%) women; mutations in BRCA1 (22/47, 46.8%) and BRCA2 (9/47, 19.1%) were the most common, with 34% of mutations present in non-BRCA genes. Patients qualifying the testing criteria had a higher risk of having a P/LP mutation (NCCN: 23.6% vs. 7.04%, p = 0.03; MCG plus: 24.8% vs. 7.2%, p = 0.01). The sensitivity of the NCCN criteria was 88.6% (75.4-96.2) and 86.36% (72.65-94.83) for MCG plus. More than 95% sensitivity was achieved if all women up to 60 years of age were tested. Cascade testing was performed in 31 previous (16/44 families), with 23 testing positive. CONCLUSIONS: The frequency of P/LP mutations in India is high, with significant contribution of non-BRCA genes. Testing criteria need modification to expand access to testing.

RESUMEN

Background & objectives: High mortality has been observed in the cancer population affected with COVID-19 during this pandemic. We undertook this study to determine the characteristics and outcomes of cancer patients with COVID-19 and assessed the factors predicting outcome. Methods: Patients of all age groups with a proven history of malignancy and a recent diagnosis of SARS-CoV-2 infection based on nasal/nasopharyngeal reverse transcriptase (RT)-PCR tests were included. Demographic, clinical and laboratory variables were compared between survivors and non-survivors groups, with respect to observed mortality. Results: Between May 11 and August 10, 2020, 134 patients were included from the three centres and observed mortality was 17.1 per cent. The median age was 53 yr (interquartile range 39-61 yr) and thirty four patients (25%) were asymptomatic. Solid tumours accounted for 69.1 per cent and breast cancer was the most common tumour type (20%). One hundred and five patients (70.5%) had received chemotherapy within the past four weeks and 25 patients (19.3%) had neutropenia at presentation. On multivariate analysis, age [odds ratio (OR) 7.99 (95% confidence interval [CI] 1.18-54.00); P=0.033], haemoglobin [OR 6.28 (95% CI 1.07-37.04); P=0.042] neutrophil-lymphocyte ratio [OR 12.02 (95% CI 2.08-69.51); P=0.005] and baseline serum albumin [OR 18.52 (95% CI 2.80-122.27); P=0.002], were associated with higher mortality. Recent chemotherapy, haematological tumours type and baseline neutropenia did not affect the outcome. Interpretation & conclusions: Higher mortality in moderate and severe infections was associated with baseline organ dysfunction and elderly age. Significant proportion of patients were asymptomatic and might remain undetected.

RESUMEN

Extra-nodal (NK/T) cell lymphoma (NKTCL) of nasal type (ENKL) presents with extranodal involvement and is associated with EBV. They are localized primarily to nasal and upper airway region but can rarely involve skin, testis, intestine, muscle, or present as a disseminated disease. We present a case of a 65-year-old male presented with bilateral orbital swelling, right parotid swelling, fever, mediastinal nodes, pleural effusion and hepatomegaly. Cytology of pleural fluid showed monomorphic lymphoid cells with folded nuclei, vesicular chromatin, inconspicuous nucleoli and granular cytoplasm. Few histiocytes showing hemophagocytosis were also noted in a background of inflammatory cells. Flow cytometric immunophenotyping of pleural fluid showed abnormal lymphoid cells which were positive for CD45, CD2 and CD56. Histopathological examination of the right eye swelling showed many atypical lymphoid cells which were positive for CD56 and negative for B and T cell markers. Based on morphological and immunophenotypic features a diagnosis of NKTCL, extra-nasal type was suggested. Patient succumbed to the disease despite aggressive therapy.

RESUMEN

BACKGROUND AND AIM: Demonstration of villous abnormalities is an essential component of diagnosis of celiac disease (CeD) that requires duodenal biopsies. There is a need for non-invasive biomarker(s) that can predict the presence of villous abnormalities. METHODS: Levels of plasma citrulline, plasma intestinal fatty acid binding protein (I-FABP), and serum regenerating gene 1α (Reg1α) were estimated in treatment naïve patients with CeD and controls. The levels of these biomarkers and their cyclical pattern were validated in a predicted model of enteropathy. Optimum diagnostic cut-off values were derived, and the results were further validated in a prospective validation cohort. RESULTS: While level of plasma citrulline was significantly lower, the levels of plasma I-FABP and serum Reg1α were significantly higher in patients with CeD (n = 131) in comparison with healthy (n = 216) and disease controls (n = 133), and their levels reversed after a gluten-free diet (GFD). In the model of predicted enteropathy (n = 70), a sequential decrease and then increase in the level of plasma citrulline was observed; such a sequential change was not observed with I-FABP and Reg1α. The diagnostic accuracy for prediction of presence of villous abnormality was 89% and 78% if citrulline level was  ≤ 30 µM/L and I-FABP levels were ≥ 1100 pg/mL, respectively. The results were validated in a prospective validation cohort (n = 104) with a sensitivity and specificity of 79.5% and 83.1%, respectively, for predicting villous abnormalities of modified Marsh grade > 2 at calculated cut-off values of citrulline and I-FABP. CONCLUSIONS: Plasma citrulline  ≤ 30 µM/L is the most consistent, highly reproducible non-invasive biomarker that can predict the presence of villous abnormality and has the potential for avoiding duodenal biopsies in 78% patients suspected to have CeD.

RESUMEN

Metronomic chemotherapy transitioned from the bench to bedside in the early 2000s and since then has carved a niche for itself in pediatric oncology. It has been used solely or in combination with other modalities such as radiotherapy, maximum tolerated dose chemotherapy, and targeted agents in adjuvant, palliative, as well as maintenance settings. No wonder, the resulting medical literature is extremely heterogeneous. In this review, the authors review and synthesize the published literature in pediatric metronomics giving a glimpse of its history, varied applications, and evolution of this genre of chemotherapy in pediatric cancers. Limitations, future prospects, and grey areas are also highlighted.

RESUMEN

INTRODUCTION: Nasopharyngeal carcinoma (NPC), arising from nasopharyngeal epithelium is caused by Epstein-Barr virus (EBV). It is common in South China, South East Asia and North East India. The aim and objectives of this study were to determine the prevalence of EBV in formalin-fixed paraffin-embedded (FFPE) tissue sections of clinically suspected NPC patients, correlate the results of polymerase chain reaction (PCR) with histopathology findings, and to determine the utility of tissue EBV DNA as a diagnostic bio-marker. MATERIALS AND METHODS: 31 FFPE tissue samples were collected from clinically suspected NPC patients from April 2018-December 2019. Histopathological diagnosis was done by examination of Hematoxylin and Eosin stained slides. Presence of EBV was detected by EBNA-1 PCR. IHC was performed using EBV Latent Membrane Protein 1. RESULTS: Of the 31 clinically suspected NPC cases, 15 (48.4 %) were histopathological confirmed NPC. Of these15, 13 (86.6 %) were non-keratinising undifferentiated NPC, and one each were keratinising NPC and non-keratinising differentiated NPC respectively. EBV EBNA1 PCR was positive in 35.5 % (11/31) of clinically suspected NPC cases. Of the 11 PCR positive cases, 9 (81.8 %) were histopathological confirmed NPC. Of the 31 clinically suspected NPC cases, IHC was indicated in 23 biopsies. Of which, 12 (52.2 %) were positive for LMP1 in the abnormal cells. Of the 12 IHC positive samples, 10 were NPC cases. CONCLUSION: EBV DNA as an indicator towards NPC among clinically suspected cases had a sensitivity of 60 % and specificity of 87.5 %. In this study, addition of EBV DNA detection by PCR from FFPE tissue sections could confirm EBV association in 20 % of cases where it was not detected by EBV LMP1 IHC, thus helped in increasing the detection of EBV positivity in NPC cases. Early diagnosis of NPC will improve the cure rate and hence reduce the morbidity and mortality rates.

RESUMEN

INTRODUCTION: Hand foot skin reaction (HFSR) is a common dose-limiting adverse effect of multi kinase inhibitors (MKI) whose mechanism is not fully understood, and the prophylaxis is inadequate. OBJECTIVE: In this pilot study, a double-blind, randomized placebo-controlled trial was conducted to evaluate the effect of topical urea in secondary prevention of sunitinib-induced HFSR in renal cell cancer patients. METHODS: Out of 55 screened patients, 14 were randomized to receive topical urea or placebo for four weeks. The association of HFSR with drug levels of sunitinib and its metabolite (n-desethyl sunitinib), genetic polymorphism of VEGFR2 gene, quality of life (QOL) and biochemical markers was also assessed. RESULTS: The results showed that urea-based cream was not superior to placebo (P = .075). There was no change in the QOL in both the groups. Single nucleotide polymorphism was checked for two nucleotides rs1870377 and rs2305948 located in VEGFR2 gene on chromosome 4. SNP (variant T > A) at rs1870377 was associated with appearance of new HFSR as compared to the wild type, although the association was not statistically significant (OR 0.714). There was no statistically significant difference between mean plasma levels of sunitinib and N-desethyl sunitinib in urea arm as compared to placebo arm as compared to placebo. The best fit population pharmacokinetic model for sunitinib was one compartment model with first order absorption and linear elimination. The median (IQR) of population parameters calculated from the population pharmacokinetics model for Ka, V and Cl was 0.22 (0.21-0.24) h-1, 4.4 (4.09-4.47) L, 0.049 (0.042-0.12) L/hr, respectively. CONCLUSION: The study suggested that the urea-based cream was not superior to placebo in decreasing the appearance of new HFSR in renal cancer patients receiving 4:2 regimen of sunitinib.

RESUMEN

High-dose chemotherapy and autologous stem cell transplant (ASCT) is the standard of care treatment in relapsed/refractory Hodgkin lymphoma (rrHL). Published long-term follow-up data concerning this modality from the Indian subcontinent is lacking. In this retrospective study, the data on adults (> 16 years) with biopsy-confirmed rrHL who were autografted from 1 January 2000 to 31 December 2021 at our transplant unit were analyzed. Progression-free survival (PFS) was defined as time from transplant to disease progression or death due to any cause. Overall survival (OS) was determined from date of transplant to date of death due to any cause. Overall, 134 patients with Hodgkin lymphoma underwent ASCT. At a median follow-up of 38.2 (range, 0.1-240) months, 5 years PFS was 45.3% (95% CI 35.4-54.4). The probability of OS at 5 years was 60.5% (95% CI 49.6-69.6). Eleven (8.2%) patients suffered transplant-related mortality by 100 days. Post-transplant persistent disease, pre-transplant serum hypoalbuminemia (< 3.5 g/dl) and chemo-resistance (< PR after last salvage regimen) of tumour at transplant were independent prognostic factors associated with worse PFS in multivariable analysis. Likewise, age ≥ 30 years, ECOG performance status ≥ 1 and residual disease after transplantation correlated with inferior OS. Long-term outcomes of rrHL patients undergoing ASCT in India match those from the developed world in the era of peripheral blood stem cell transplantation. Pre-transplant performance status, chemo-sensitivity of disease, serum albumin and post-transplant remission status determined survival in our cohort. Supplementary Information: The online version contains supplementary material available at 10.1007/s12288-023-01690-x.

RESUMEN

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%.

RESUMEN

PURPOSE: Serial patient-reported outcome (PRO) measurements in clinical practice are associated with a better quality of life and survival. Recording electronic PROs using smartphones is an efficient way to implement this. We aimed to assess the feasibility of the electronically filled Edmonton Symptom Assessment System (e-ESAS) scale in the lower-middle-income country (LMIC) setting. METHODS: Baseline clinical features and conventional paper-based ESAS (p-ESAS) were collected in newly diagnosed patients with solid organ tumors. Text message link was sent to these patients for filling e-ESAS. ESAS was categorized into physical, psychological, and total symptom domains. Scores were divided into none to mild (0-3) and moderate to severe (4-10). Intraclass correlation coefficients (ICCs) were used to determine the correlation between p-ESAS and e-ESAS. Multivariable logistic regression was used to identify independent factors affecting symptom burden. RESULTS: Of 1,160 participants who filled out p-ESAS, 595 completed both e-ESAS and p-ESAS questionnaires and were included in the final analysis. Moderate to severe physical, psychological, and total symptom scores were seen in 39.8%, 40%, and 39% of participants. Tiredness and anxiety were the most common physical and psychological symptoms, respectively. ICCs between the p-ESAS and e-ESAS varied between 0.75 and 0.9. Total symptom scores were independently predicted by metastatic disease (odds ratio [OR], 1.83; 95% CI, 1.26 to 2.67; P = .001) and a higher level of education (OR, 0.42; 95% CI, 0.25 to 0.72; P = .001). CONCLUSION: Paper-based and electronically filled ESASs have good intraobserver reliability across individual symptoms and domain scores in a representative cohort at a tertiary care institute in the LMIC. This may help us incorporate e-ESAS in routine clinical care in the real-world setting with financial, infrastructural, and manpower limitations.

RESUMEN

T-acute lymphoblastic leukemia (T-ALL) is a heterogeneous malignancy characterized by the abnormal proliferation of immature T-cell precursors. Despite advances in immunophenotypic classification, understanding the molecular landscape and its impact on patient prognosis remains challenging. In this study, we conducted comprehensive RNA sequencing in a cohort of 35 patients with T-ALL to unravel the intricate transcriptomic profile. Subsequently, we validated the prognostic relevance of 23 targets, encompassing (i) protein-coding genes-BAALC, HHEX, MEF2C, FAT1, LYL1, LMO2, LYN, and TAL1; (ii) epigenetic modifiers-DOT1L, EP300, EML4, RAG1, EZH2, and KDM6A; and (iii) long noncoding RNAs (lncRNAs)-XIST, PCAT18, PCAT14, LINC00202, LINC00461, LINC00648, ST20, MEF2C-AS1, and MALAT1 in an independent cohort of 99 patients with T-ALL. Principal component analysis revealed distinct clusters aligning with immunophenotypic subtypes, providing insights into the molecular heterogeneity of T-ALL. The identified signature genes exhibited associations with clinicopathologic features. Survival analysis uncovered several independent predictors of patient outcomes. Higher expression of MEF2C, BAALC, HHEX, and LYL1 genes emerged as robust indicators of poor overall survival (OS), event-free survival (EFS), and relapse-free survival (RFS). Higher LMO2 expression was correlated with adverse EFS and RFS outcomes. Intriguingly, increased expression of lncRNA ST20 coupled with RAG1 demonstrated a favorable prognostic impact on OS, EFS, and RFS. Conclusively, several hitherto unreported associations of gene expression patterns with clinicopathologic features and prognosis were identified, which may help understand T-ALL's molecular pathogenesis and provide prognostic markers.

RESUMEN

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.
