Breast lymphomas: Clinical and pathological insights from a tertiary cancer care center in India.

BACKGROUND: Breast lymphomas are a rare group of malignancies that are further subdivided into primary and secondary. AIMS: To study the pathological and clinical course of breast lymphomas. MATERIALS AND METHODS: This is a retrospective analysis of patients treated at our institute over a period of 4.5 years from September 2018 to February 2023. The details of all the patients diagnosed with breast lymphoma were reviewed and analysed for the histomorphological, immunohistochemical, clinical, and treatment details. Appropriate statistical analysis including Kaplan-Meier methods was used. RESULTS: Out of 11 cases of breast lymphoma, five were primary and six were secondary. It was seen predominantly in females (82%) and the age range was 31 to 73 years. Diffuse large B cell lymphoma (DLBCL) was the predominant morphology (73%), along with single rare cases of ALK-negative anaplastic large cell lymphoma, Burkitt lymphoma, and small lymphocytic lymphoma. The treatment details were analyzed for 7 patients. The median follow-up was 28 months. Rituximab along with CHOP regimen or its variants was commonly used as first-line treatment with initial response rates of 71%. The median progression-free survival was 5 months. The median overall survival was 15 months. CONCLUSION: Lymphomas of the breast are rare but it is crucial to differentiate them from the commoner breast carcinomas as the treatment and prognosis vary vastly.

Assessing frailty in older Indian patients before cancer treatment: Comparative analysis of three scales and their implications for overall survival.

INTRODUCTION: Frailty, characterized by ageing-related vulnerability, influences outcomes in older adults. Our study aimed to investigate the relationship between frailty and clinical outcomes in older Indian patients with cancer. MATERIALS AND METHODS: Our observational single-centre study, conducted at Tata Memorial Hospital from February 2020 to July 2022, enrolled participants aged 60 years and above with cancer. Frailty was assessed using the Clinical Frailty Scale (CFS), G8, and Vulnerable Elders Survey (VES)-13. The primary objective was to explore the correlation between baseline frailty and overall survival. Statistical analyses include Kaplan-Meier, Cox proportional hazards, and Harrell's C test. RESULTS: A total of 1,177 patients (median age 68, 76.9% male) were evaluated in the geriatric oncology clinic. Common malignancies included lung (40.0%), gastrointestinal (35.8%), urological (11.9%), and head and neck (9.0%), with 56.5% having metastatic disease. Using CFS, G8, and VES-13 scales, 28.5%, 86.4%, and 38.0% were identified as frail, respectively. Median follow-up was 11.6 months, with 43.3% deaths. Patients fit on CFS (CFS 1-2) had a median survival of 28.02 months, pre-frail (CFS 3-4) 13.24 months, and frail (CFS ≥5) 7.79 months (p < 0.001). Abnormal G8 (≤14) and VES-13 (≥3) were associated with significantly lower median survival (p < 0.001). Multivariate analysis confirmed CFS's predictive power for mortality (p < 0.001), with hazard ratios [HRs] for pre-frail at 1.61(95% confidence interval [CI] 1.25 to 2.06) and frail at 2.31 (95%CI 1.74 to 3.05). G8 ≤ 14 had HR 2.00 (95%CI 1.42 to 2.83), and abnormal VES-13 had HR 1.36 (95%CI 1.11-1.67). In the likelihood ratio test, CFS significantly improved the model fit (p < 0.001). Harrell's C index for survival prediction was 0.62 for CFS, 0.54 for G8, and 0.58 for VES-13. DISCUSSION: In conclusion, our study highlights varying frailty prevalence and prognostic implications in older Indian patients with cancer, emphasizing the need for personalized care in oncology for this aging population. We would recommend using CFS as a tool to screen for frailty for older Indian patients with cancer.

In Vitro Assessment of Antimicrobial Activity of Novel Fluoroquinolone, Levonadifloxacin (WCK 771) Against Multi-Drug-Resistant Clinical Isolates from Cancer Patients in India.

Introduction: Rapid increase in antimicrobial-resistance is leading to urgent need for newer broad-spectrum antimicrobials. Therefore, we have evaluated the antimicrobial résistance spectrum of India-discovered novel antibiotics (levonadifloxacin) against clinical isolates recovered from cancer patients. Materials and Methods: The study was conducted in the microbiology department, over a period of 1 year between May 2021 and June 2022 and 374 consecutive and nonduplicate Gram-positive (GPC) and MDR Gram Negative Bacteria (GNB) isolate were analyzed from 3,880 cancer patients in study. The identification and antimicrobial sensitivities of bacterial isolates were performed according to standard laboratory protocols by using automated identification system (VITEK-2-8.01; BioMérieux, Germany). The activity of levonadifloxacin and comparator antibiotics was evaluated using disk diffusion methods as per Clinical and Laboratory Standards Institute 2022 guidelines. Results: The mean age of the patients were 51.6 ± 14.59 years with male: female ratio of 1.2:1. The prevalence of GPC was 167 (44.65%) and MDR-GNB was 207 (55.34%). The most common GPC was Staphylococcus aureus; 97 (58.08%) followed by Enterococcus species 66 (39.52%). In GNB, Escherichia coli; 93 (44.92%) was the most common followed by Klebsiella pneumoniae; 45 (21.73%). Levonadifloxacin susceptibility was present in 98.7% methicillin-resistant S. aureus and 96% methicillin-susceptible S. aureus and 77.1% Enterococcus-species. Additionally, all the fluoroquinolones-resistant S. aureus isolates were susceptible to levonadifloxacin (WCK-771) except one isolate. Also, levonadifloxacin-(WCK-771) exhibits 100% susceptibility fluoroquinolone susceptible GNB, such as E. coli, K. pneumoniae, Pseudomonas species, and Acinetobacter species. Interestingly, all fluoroquinolones-resistant Salmonella species and Stenotrophomonas maltophilla exhibited 100% susceptibility to levonadifloxacin (WCK-771). Conclusion: Levonadifloxacin (WCK-771) possesses potent activity against all the MDR Gram-positive pathogens including the coverage of susceptible Enterobacterales and MDR S. maltophilla and Burkholderia cepacia suggesting its potential utility in the management of polymicrobial infections.

A Retrospective Cohort Study to Evaluate the Outcomes of HIV-Associated High-Grade B-Cell Non-Hodgkin Lymphoma (NHL) Treated with Dose Adjusted EPOCH (+/-R) Regimen.

High-grade B-cell NHL's are more common in seropositive patients. They are biologically different from their seronegative counterparts. We report our analysis on our cohort of patients who were treated with DA-EPOCH(+/-R). We retrospectively analyzed treatment-naïve HIV-associated High-grade B-cell NHL patients (aged ≥ 18) treated with DA-EPOCH(+/-R) regimen from 2011 to 2015. Descriptive statistics were summarized with median and range; survival outcomes were analyzed with Kaplan-Meier method. The cohort comprised of 40 patients [DLBCL(19), Burkitt's Lymphoma(16), High-grade B-Cell Lymphoma-Unclassifiable(09), and Plasmablastic Lymphoma(01)] and the median CD4 + T cell count was 202/mm3. CNS prophylaxis was administered with intrathecal methotrexate to 90% of patients. With a median follow-up of 72 months, an estimated 5-year OS was 82.5%, and 5-PFS was 77.5%. There were 9 deaths, and 9 patients had progression. At least 4 cycles of chemotherapy were administered to 35 (93%) patients, with 28 (70%) receiving 6 cycles. Grade 3-4 toxicities were seen in 33 (83%) patients- febrile neutropenia (65%) being the most common followed by mucositis (25%) and peripheral neuropathy (13%). There was no difference in survival based on IPI, CD 4 + T cell count, CDI, or duration of HIV. DA-EPOCH(+/-R) is a highly effective regimen in seropositive high-grade B-cell lymphoma, even in the presence of adverse features.

Trastuzumab Plus Gemcitabine-Cisplatin for Treatment-Naïve Human Epidermal Growth Factor Receptor 2-Positive Biliary Tract Adenocarcinoma: A Multicenter, Open-Label, Phase II Study (TAB).

PURPOSE: Human epidermal growth factor receptor 2 (HER2) overexpression is seen in 4%-16% of biliary tract cancers (BTCs). We aimed to evaluate the clinical activity of gemcitabine-cisplatin (GC) plus anti-HER2 antibody trastuzumab as initial treatment in HER2-positive BTCs. METHODS: This study was an investigator-initiated, open-label, single-arm, multi-institutional, phase II trial in adult patients with HER2-positive (defined as immunohistochemistry [IHC] 3+ or IHC 2+ and fluorescent in situ hybridization-positive), treatment-naïve BTCs. The primary end point of the study was 6-month progression-free survival (PFS). Next-generation sequencing was performed on tissue samples to evaluate mutational status. RESULTS: From March 2020 to August 2022, of the 876 screened patients, 118 (13.4%) were found to have HER2-positive status, of whom 90 were enrolled in the study. Most patients had GBC (n = 96; 96%) with two or more sites of metastatic disease (n = 70; 78%). With a median follow-up of 17.3 (95% CI, 15.22 to 19.32) months, 72 patients had disease progression with a median PFS of 7 (95% CI, 6.2 to 7.8) months. The diagnosis to event 6-month PFS rate was 75.6% (95% CI, 66.6 to 84.6). A complete or partial response was seen in 50 (55.5%) patients and 22 (24.4%) patients had stable disease as the best response to treatment, for an overall disease control rate of 80%. The presence of isolated TP53 mutations was associated with inferior PFS compared with other mutations (TERT promoter, HER2, PIK3CA, etc) or no detected mutations (6.51 v 12.02 v 10.58 months; P < .001). CONCLUSION: The combination of GC and trastuzumab achieved its primary end point of improving PFS compared with historical data in the treatment-naïve HER2-positive BTC. Evaluating additional mutations such as TP53 and PIK3CA along with HER2 testing may help to preferentially select patients for anti-HER2 therapy in the future (Clinical Trial Registry India number: CTRI/2019/11/021955).

Pattern of Care and Outcomes of Gallbladder Cancer Patients: Retrospective Study from a High Incidence Region in India.

Lakhan KasyapIntroduction Gallbladder cancer (GBC) is the 20th most common cancer in India with a crude incidence rate of 2.3 per 100,000 persons. Of note, it is relatively common in states which fall in the Gangetic plains. Patients often present in the advanced stage and have an unfavorable prognosis. Materials and Methods From January to June 2021, 170 treatment-naive GBC (adenocarcinoma) patients who were registered at a tertiary care cancer center in North India, were included. Data were extracted from electronic medical records and was analyzed with SPSS. Results Median age was 56 years (range 32-77 years) and 65.5% ( n = 112) were female. Incidental GBC was found in 20% patient ( n = 34). Majority of patients (79.4%, n = 135) had preserved performance status. Advanced GBC was present in 85.8% ( n = 146) patients (locally advanced = 37.0% and metastatic = 48.8%). Biliary drainage procedure was performed in 24% of patients (68% of patients with obstructive jaundice). More than half of patients (53.5%) were lost to follow-up without any treatment. There were 33 patients (19.4%) who underwent surgery and 20 of them received neoadjuvant chemotherapy. Adjuvant chemotherapy and adjuvant radiotherapy were received by 13 and 2 patients, respectively. Palliative chemotherapy was administered to 46 patients. The most common chemotherapy regimen was gemcitabine-cisplatin. At a median follow-up of 1.7 months (95% confidence interval, 1-2.4 months), 42 patients (24%) progressed and 24 patients (14%) died, with 6 months estimated progression-free survival and overall survival being 60.2 and 79%, respectively. Conclusion GBC is an aggressive and lethal malignancy predominantly affecting females in the fifth decade with dismal outcomes. Improved access to health care, an aggressive approach in operable cases, and optimization of systemic and adjuvant therapy are the need of the hour.

Long-Term Outcomes of Crizotinib Treated ALK-Positive Lung Cancer Patients: A Retrospective Audit of Prospective Data from Resource-Constrained Settings.

Akhil KapoorPurpose Crizotinib has been one of the standard treatment options for the treatment of anaplastic lymphoma kinase (ALK) rearranged non-small cell lung cancer (NSCLC) based on higher progression-free survival (PFS) and objective response rates in phase III clinical trials. However, real-world data about the long-term efficacy and toxicity of crizotinib is limited. Methods A retrospective analysis of all patients with ALK-positive NSCLC, treated with crizotinib between March 2014 and December 2016, was performed. The main outcomes measured were PFS, overall survival (OS), and adverse effects. Results One hundred and eighty-eight patients treated with crizotinib during this period were included in this study. The median age was 50 years (range: 24-74) with a majority being males (73.2%) and 80.3% with a performance status of 0 to 1. The median duration of follow-up was 49.4 months (range: 3.4-86.3%). The median PFS of crizotinib was 17.3 months (95% confidence interval [CI], 13.0-21.6) and 12.8 months (95% CI, 8.1-17.6) when used in first line or subsequent lines, respectively. The median OS was 38.3 months (95% CI, 28.4-48.2). The patients who received crizotinib in the first line had a median OS of 45.5 months (95% CI, 29.6-61.4) as compared with 29.7 months (95% CI, 22.2-37.2) for those who received in subsequent line (hazard ratio, 0.6, 95% CI, 0.4-0.9, p =0.022). The most common all grade toxicities include transaminitis, anemia, fatigue, and corrected QT prolongation. Conclusion This real-world study confirms the long-term beneficial effects of crizotinib in ALK rearranged NSCLC with favorable toxicity profile like that of the registration studies, in resource constrained settings.

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

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

The current status of geriatric oncology in India.

Geriatric oncology in India is relatively new. The number of older persons with cancer is increasing exponentially; at our institution, 34% of patients registered are 60 years and over. Apart from the Tata Memorial Hospital in Mumbai, there are currently no other Indian centers that have a dedicated geriatric oncology unit. Geriatric assessments (GAs) are done sporadically, and older patients with cancer are usually assessed and treated based on clinical judgement. Challenges to increasing the uptake of GA include a lack of training/time/interest or knowledge of the importance of the GA. Other challenges include a lack of trained personnel with expertise in geriatric oncology, and a paucity of research studies that seek to advance the outcomes in older Indian patients with cancer. We anticipate that over the next 10 years, along with the inevitable increase in the number of older persons with cancer in India, there will be a commensurate increase in the number of skilled personnel to care for them. Key goals for the future include increased research output, increased number of dedicated geriatric oncology units across the country, India-specific geriatric oncology guidelines, geriatric oncology training programs, and a focus on collaborative work across India and with global partners. In this narrative review, we provide a broad overview of the status of geriatric oncology in India, along with a description of the work done at our center. We hope to spark interest and provide inspiration to readers to consider developing geriatric oncology services in other settings.

Incurable advanced salivary gland tumours: a retrospective analysis and peek into the perplexing clinical and molecular intricacies from a tertiary care centre in India.

Background: Salivary gland tumours are rare cancers with variable course and prognosis. There is a paucity of data, especially for the advanced stages. Materials and methods: This is a retrospective analysis carried out in our institute. All patients seeking treatment for incurable advanced salivary gland tumours from October 2018 to September 2022 were included. Relevant clinical data were collected and appropriate statistical analysis was applied. Results: 30 patients were included in the analysis. The parotid gland was the most common site of origin (73%). Adenoid cystic carcinoma (ACC) and salivary duct carcinoma (SDC) were equally (37%) the most common pathological subtypes. The majority of patients were males (73%) and lungs (57%) were the most common site of metastases. On molecular analysis, SDC had high rates of androgen receptor (AR) (90%) and human epidermal growth factor receptor 2 (HER2) (55%) positivity. Mucoepidermoid carcinoma (MEC) had AR and HER2 positivity rates of 17% and 20%, respectively, while for ACC it was even lower. A variety of treatment regimens including hormonal therapy, anti-HER2 targeted therapy and chemotherapy were used in first-line treatment. With an overall response rate (ORR) of 10/21 (48%), only 9/21 (43%) went on to receive second-line treatment with an ORR of 4/9 (44%). The progression-free survival (PFS) with first-line treatment (PFS1) was a median of 5 months. The median PFS1 was worst for MEC. The median overall survival (OS) was 10 months. Median OS for ACC, SDC and MEC were 11, 10 and 7 months, respectively. At 24 months, ACC had much higher survival (50%) than others (10%) indicating a proportion of ACC with an indolent course. Conclusion: Our analysis highlights the variable disease biology of advanced salivary gland tumours and throws light on the various possible treatment targets and strategies. Molecular profiling and advancement in targeted therapies are expected to increase survival in this group of rare cancers.

Response assessment of post-treatment head and neck cancers to determine further management using NI-RADS (Neck Imaging Reporting and Data System): a subgroup analysis of a randomized controlled trial.

Objective: Interpreting complex post-treatment changes in head and neck cancer (HNC) is challenging with further added perplexity due to variable interobserver interpretation and hence evolved the NI-RADS lexicon. We evaluated the accuracy of NI-RADS in predicting disease status on 1st post-treatment follow-up CECT in a homogenous cohort of those who received only chemoradiation. Methods: Retrospective analysis of imaging was done for LASHNC patients who received radical chemoradiation in an open-label, investigator-initiated, phase 3 randomized trial (2012-2018) randomly assigned to either radical radiotherapy with concurrent weekly cisplatin (CRT) or CRT with the same schedule plus weekly nimotuzumab (NCRT). 536 patients were accrued, and 74 patients who did not undergo PET/CECT after 8 weeks post-CRT were excluded. After assessing 462 patients for eligibility to allocate NI-RADS at primary and node sites, 435 cases fell in the Primary disease cohort and 412 cases in the Node disease cohort. We evaluated sensitivity, disease prevalence, the positive and negative predictive value of the NI-RADS lexicon, and accuracy, which were expressed as percentages. We also prepared flow charts to determine concordance with allocated NI-RADS category and established accuracy with which it can identify disease status. Results: Out of 435 primary disease cohort, 92%, 55%, 48%,70% were concordant and had 100%, 72%, 70%, 82% accuracy in NI-RADS1 (n=12), NI-RADS2 (n=261), NIRADS3 (n=105), and NI-RADS 4 (n=60) respectively. Out of 412 nodes disease cohort, 95%, 90%, 48%, 70%were concordant and had 92%, 97%, 90%, 67% accuracy in NI-RADS1 (n=57), NI-RADS2 (n=255), NI-RADS3 (n=105) and NI-RADS4 (n=60) respectively. % concordance of PET/CT and CECT across all primary and node disease cohorts revealed that PET/CT was 91% concordant in primary NI-RADS2 as compared to 55% concordance of CECT whereas concordance of CECT was better with 57% in primary NI-RADS3 cohort as compared to PET/CT concordance of 41%. Conclusion: The accuracy with which the NI-RADS lexicon performed in our study at node sites was better than that at the primary site. There is a great scope of research to understand if CECT performs better over clinical disease status in NI-RADS 3 and 4 categories. Further research should be carried out to understand if PET/CECT can be used for close interval follow-up in stage III/IV NI-RADS 2 cases.

Validation of the Onco-MPI in predicting short-term mortality in older Indian patients with cancer.

INTRODUCTION: The number of older patients with cancer is increasing exponentially worldwide, and a similar trend has also been noted in India. The Multidimensional Prognostic Index (MPI) strongly correlates the presence of individual comorbidities with mortality, and the Onco-MPI prognosticates patients accurately for overall mortality. However, limited studies have evaluated this index in patient populations beyond Italy. We evaluated the performance of the Onco-MPI index in predicting mortality in older Indian patients with cancer. MATERIALS AND METHODS: This observational study was conducted between October 2019 and November 2021 in the Geriatric Oncology Clinic at Tata Memorial Hospital in Mumbai, India. The data of patients aged ≥60 years with solid tumors who underwent a comprehensive geriatric assessment was analysed. The study's primary aim was to calculate the Onco-MPI for patients in the study and correlate it with one-year mortality. RESULTS: A total of 576 patients aged ≥60 years were included in the study. The median age (range) of the population was 68 (60-90) years, and 429 (74.5%) were male. After a median follow-up of 19.2 months, 366 (63.7%) patients had died. The proportion of patients classified as low risk (0-0.46), moderate risk (0.47-0.63) and high risk (0.64-1.0) were 38% (219 patients), 37% (211 patients) and 25% (145 patients), respectively. There was a significant difference in one-year mortality rates between the low-risk patients compared to medium and high-risk patients (40.6% vs 53.1% vs 71.7%; p < 0.001). DISCUSSION: The current study validates the Onco-MPI as a predictive tool for estimating short-term mortality in older Indian patients with cancer. Further prospective studies need to build on this index to obtain a score with greater discrimination in the Indian population.

Clinical Profile, Practice Pattern, and Outcomes With First-Line Therapy in ALK-Positive Lung Cancer: Real-World Data From Resource-Constrained Settings.

Introduction: ALK inhibitors are one of the success stories in precision medicine for treating patients with advanced ALK-positive NSCLC. Nevertheless, developing countries have substantial constraints in using ALK inhibitors, with limited data from India. Methods: An audit of a prospectively collected database of patients with advanced ALK-positive NSCLC treated from January 2013 to March 2018 was conducted. The SPSS version 20.0 was used for statistical analysis. Results: A total of 441 patients were available for analysis; 62.5% were males, median age was 50 (range: 19-75) years, and 78.3% had Eastern Cooperative Oncology Group performance status of 0 to 1. When all the lines of therapies were included in the analysis, ALK inhibitors could be used in 379 (85.9%) of the total ALK-positive patients and 292 patients (66.2%) received ALK inhibitors in the first line in any strategy. The major reason for not starting ALK inhibitors upfront was financial constraints in 69% of the patients. The median progression-free survival on first-line therapy for the entire cohort was 14.1 months (95% confidence interval [CI]: 12.2-15.9), with a significant difference between patients receiving ALK inhibitor in first line in any strategy versus not in first line (17.2 mo [95% CI: 14.5-19.9] versus 5.9 mo [95% CI: 4.2-7.6], p < 0.001). The median overall survival was 30.7 months (95% CI: 27.3-34.2), with 37.6 months (95% CI: 28.1-47.1) for ALK inhibitor in the first line versus 20.5 months (95% CI: 15.8-25.1) for subsequent lines of therapy (p < 0.001). Conclusions: Most of our patients with ALK-positive NSCLC were exposed to ALK inhibitors through various support mechanisms. Those patients who could receive ALK inhibitors in the first line had a significant survival advantage as compared with others.

Perioperative Modified FLOT Versus EOX in Locally Advanced Resectable Gastric and Gastro-Oesophageal Junction Adenocarcinoma: Results of a Matched-Pair Analysis.

BACKGROUND AND OBJECTIVES: There is limited real-world data on the efficacy of 2-weekly cycles of docetaxel, oxaliplatin, leucovorin, and fluorouracil (FLOT) compared to epirubicin, oxaliplatin, and capecitabine (EOX) as perioperative therapy in esophagogastric adenocarcinomas (EGAC). METHODS: The data of 611 patients with EGAC treated with perioperative chemotherapy and planned for curative resection between January 2013 and December 2019 were retrieved. Patients receiving EOX and a dose-modified version of FLOT (mFLOT) were evaluated. A 1:1 matching, using age, tumour location, signet ring histology, and Eastern Cooperative Oncology Group performance status, without replacement was performed by using nearest neighbour matching method. The primary endpoint of the study was 3-year event-free survival (EFS). RESULTS: A total of 593 patients (261 with EOX and 332 with mFLOT) were matched. One hundred and nighty-eight patients (76%) and 285 patients (86%) in the EOX and mFLOT cohorts underwent curative resection, respectively (p = 0.002). With a median follow-up of 35 and 53 months, respectively, the primary outcome of 3-year EFS was statistically superior in patients receiving mFLOT as compared to the EOX regimen (60% vs. 39%; p < 0.001). There was a greater incidence of grade 3 and grade 4 neutropenia (neoadjuvant: 18% vs. 2%; p < 0.001, adjuvant: 18% vs. 1%; p = 0.001) and febrile neutropenia (neoadjuvant: 8% vs. 1.1%; p < 0.001, adjuvant: 6% vs. 0; p = 0.001) with mFLOT. INTERPRETATION AND CONCLUSION: mFLOT is associated with improved resection rates and survival in comparison to EOX as perioperative therapy in gastric adenocarcinomas in this large real-world cohort, with manageable increase in clinically relevant toxicities such as grade 3 and grade 4 febrile neutropenia and neutropenia.

An Analysis of Tolerance and Early Survival Outcomes with Perioperative Modified FLOT in Gastric Cancers.

Anant RamaswamyPurpose Perioperative chemotherapy with fluorouracil plus leucovorin, oxaliplatin, and docetaxel (FLOT) is a current standard of care for locoregionally advanced gastric adenocarcinomas. There is limited real world data with regard to the tolerance and efficacy of this regimen. Materials and Methods This is a retrospective analysis of gastric cancer patients who were offered neoadjuvant perioperative modified FLOT regimen between December 2016 and October 2018, at the Tata Memorial Hospital, Mumbai. Chemotherapy-related side-effects are reported along with overall survival (OS), as calculated by Kaplan-Meier method. Results Three hundred and forty-three consecutive patients were started on neoadjuvant chemotherapy (NACT) with mFLOT of which 298 patients (87%) completed the planned treatment. A total of 294 patients (86%) underwent curative resection of gastric cancer. Common grade 3 and grade 4 toxicities during NACT were diarrhea in 42 patients (12%) and febrile neutropenia in 27 patients (8%). Toxic death was seen in nine (2.6%) patients. A total of 264 patients (77%) completed planned adjuvant chemotherapy. Common grade 3 and grade 4 toxicities during adjuvant therapy were diarrhea in 42 patients (12%) and febrile neutropenia in 16 patients (6%). With a median follow-up of 19 months, the estimated 2-year median OS was 69.4%. Conclusion Administration of modified FLOT regimen in locoregionally advanced gastric cancers is feasible in clinical practice with high completion rates, though requiring dose modifications due to the incidence of clinically relevant grade 3 to 5 toxicities. Early outcomes with the regimen are on par with survivals from the FLOT-AIO study.

ALK-positive advanced non-small cell lung cancer patients with poor performance status: Outcomes in a real-world scenario.

Background: Anaplastic lymphoma kinase (ALK) inhibitors have shown significant efficacy in ALK -rearranged non-small cell lung cancer (NSCLC) patients with good performance status (PS) in multiple randomised studies. However, there is limited data on patients with poor performance status. Patients and methods: We carried out a retrospective analysis of prospectively collected data of patients with ALK-rearranged NSCLC and Eastern Cooperative Oncology Group (ECOG) PS of 2-4 treated at a single academic cancer centre from January 2013 to November 2018. The outcomes, progression-free survival (PFS) and overall survival (OS) were calculated from the date of diagnosis. SPSS version 20 was used for all statistical calculations. Results: Out of the total 441 ALK-positive patients, 97 (21.9%) had ECOG PS 2-4 (poor PS). The median PFS was 9.3 months (95% CI = 6.6-12.0) as compared to 14.9 months (95% CI = 13.4-16.4) for patients with a PS of 0-1 (HR = 1.38, 95% CI = 1.04-1.84, p = 0.027). The corresponding median OS were 17.9 months (95% CI = 12.8-23.1) and 33.5 months (95% CI = 28.6-38.4), respectively (HR = 1.89, 95% CI = 1.36-2.62, p < 0.001). Among poor PS patients, a subgroup of patients with PS 2 had median OS of 20.6 months (95% CI = 10.8-47.3) as compared to 8.6 months for PS 3-4 (95% CI = 7.8-27.8) (HR = 1.79, 95% CI = 1.01-3.20, p = 0.047). The patients treated with upfront ALK inhibitors had better survival as opposed to those treated with chemotherapy. On multivariate analysis, PS 3-4, smoking, stage 4 and not using ALK inhibitors as first-line therapy were associated significantly with poor outcomes. Conclusion: The ALK-rearranged NSCLC patients with poor PS derived significant benefits with ALK inhibitors. The outcomes were significantly poorer as compared to patients with PS 0-1; the subgroup of patients with PS 2 had better outcomes as compared to patients with PS 3-4.

Fumarate hydratase-deficient renal cell carcinoma in extended remission with bevacizumab and erlotinib.

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is an autosomal dominant syndrome associated with fumarate hydratase (FH) gene mutation leading to defective DNA double-strand break repair mechanism. Although these tumours have an aggressive presentation, they respond well to targeted therapy with fewer adverse effects. Here we present a case of a 42-year-old female having isolated renal cell carcinoma, papillary type 2, carrying a mutation in the FH gene without cutaneous and uterine involvement. Her tumour responded well to erlotinib and bevacizumab combination and she was on treatment for 23 months. This report adds to the current literature and can help to define treatment protocols for HLRCC.

Impact of Molecular Tumor Board on the Clinical Management of Patients With Cancer.

PURPOSE: Multidisciplinary molecular tumor boards (MTBs) help in interpreting complex genomic data generated by molecular tumor profiling and improve patients' access to targeted therapies. The purpose of this study was to assess the impact of our institution's MTB on the clinical management of patients with cancer. METHODS: This study was conducted at a tertiary cancer center in India. Cases to be discussed in the MTB were identified by molecular pathologists, scientists, or oncologists. On the basis of the clinical data and molecular test reports, a course of clinical management was recommended and made available to the treating oncologist. We determined the proportion of patients who were recommended a change in the clinical management. We also assessed compliance of the treating oncologists with MTB recommendations. RESULTS: There were 339 discussions for 328 unique patients. The median age of the cohort was 54 years (range 17-87), and the majority of the patients were men (65.1%). Of 339 cases, 133 (39.2%) were recommended continuation of ongoing therapy while the remaining 206 (60.7%) were recommended a change in clinical management. Compliance with MTB recommendations for a change in clinical management was 58.5% (79 of 138 evaluable cases). Compliance and implementation for MTB's recommendation to start a new therapy in 104 evaluable cases were 60.5% and 44.2%, respectively. A total of 248 biopsies had at least one actionable mutation. A total of 646 mutations were identified in the cohort, with EGFR being the most frequently altered gene. CONCLUSION: MTBs help in interpreting results of molecular tests, understanding the significance of molecular abnormalities, and assessing the benefits of available targeted therapies and clinical trials in the management of patients with targetable genetic alterations.

Development of a New Tool to Assess the Quality of Life of Patients with Hand-Foot Syndrome Receiving Capecitabine-Based Therapy: A Pilot Study.

Prathepa JagdishBackground Hand-foot syndrome (HFS) can result in significant deficits in health-related quality of life (HRQOL) and can lead to poor compliance, dose reduction, or interruption. This study was performed to assess the HRQOL with HFS on physical, psychological, social, and sexual aspects of patients receiving capecitabine-based chemotherapy with gastrointestinal cancer along with validating and assessing the reliability score of the questionnaire. Patients and Methods HFS-related QOL (HF-QOL) questionnaire was developed and validated in a sample of 30 patients randomly selected for this pilot study. The internal consistency of the tool was tested by calculating the Cronbach's α coefficient, while content and construct validity were assessed by Pearson's correlation. Statistical analyses were performed using SPSS version 25.0. Results Out of 30, 22 (73%) patients were males, mean age was 44 ± 13 years; 21 (70%) patients had grade 1 HFS, while 6 (20%) and 3 (10%) patients had grades 2 and 3 HFS, respectively. Cronbach's α coefficient was high for physical (0.79) and sexual scales (0.79), while it was moderately low for psychological (0.65) and social (0.53) domains. The average HF-QOL scores were 70.6 ± 13.2 in physical domain and 71.3 ± 23.7 in sexual domain indicating poor quality of life (QOL), while it was 50.9 ± 9.9 in social domain indicating moderately worse QOL. Grades 2 and 3 of HFS were found to have statistical significance on physical (0.0001), psychological (0.05), and social (0.02) domains, whereas sexual domain did not have any statistical significance (0.594). Conclusion This pilot study showed the feasibility of use and validity of a new patient-reported instrument, the HF-QOL, which measures the effect of HFS on daily activities (physical, psychological, social, and sexual domains) after capecitabine-based chemotherapy.
