Adult Philadelphia-Positive Acute Lymphoblastic Leukemia: A Single-Institution Experience in Limited-Resource Setting.

L. K. RajeevBackground Adult Philadelphia-positive (Ph + ) acute lymphoblastic leukemia (ALL) is a distinct entity with poor prognosis. Treatment with tyrosine kinase inhibitors improved responses but still with poor outcomes. We evaluated treatment outcomes in these patients treated in limited-resource settings in the absence of availability of allogeneic stem cell transplantation (ASCT). Materials and Methods We studied case record files of the adult patients diagnosed with Ph+ ALL. Results A total of 18 patients were evaluated retrospectively. The median age of presentation was 28 years. Male-to-female ratio was 1:1. Patients presented with fever and fatigue. Six patients (33.33%) presented with cervical lymphadenopathy. Clinical splenomegaly was present in 16 (88.88%) patients on palpation, whereas on ultrasonographic evaluation, all 18 patients had splenomegaly. The median size of the spleen was 15 cm. Hepatomegaly was seen in 5 (27%) patients. All 18 patients had anemia at the time of presentation. Leukocytosis was seen in 17 (94.44%) patients, whereas 1 (5.56%) patient presented with low total leukocyte count. The median platelet count at the time of presentation was 30,000/mm. 3 On peripheral smear, median number of blast cells was 55%, and on bone marrow aspiration samples, median blast percentage seen was 70%. Conventional cytogenetics was done in all the patients on bone marrow aspiration samples. Ten patients (55.55%) had t(9;22) - Ph chromosome. One patient (5.56%) on cytogenetics showed double Ph chromosome. The median value of breakpoint cluster region-ABL1 transcript in IS% was 13%. Seventeen (94.44%) received ALL protocol (BFM95) along with tyrosine kinase inhibitor (imatinib). One (5.56%) patient refused aggressive cytotoxic chemotherapy. No patient underwent ASCT. The median duration of follow-up was 7.5 months, ranging from 3 to 16 months. Median overall survival (OS) was 7.5 months and 2-year OS was 33.33%. Conclusion Poor prognosis of this disease, especially in the absence of ASCT, remains a major challenge in the treatment.

Unmasking Infection Risks in Multiple Myeloma: Insights from a Retrospective Analysis.

Multiple myeloma (MM) has witnessed significant therapeutic advancements through the introduction of proteasome inhibitors and immunomodulators, leading to improved treatment outcomes. However, infections remain a formidable challenge for MM patients. The objective of our research is to investigate the factors that can forecast infection risk in MM patients. In pursuit of this, we conducted a thorough retrospective examination of medical records from Kidwai Memorial Institute of Oncology, Bangalore, involving 145 MM patients. Out of the 145 patients analyzed, almost half (47.5%; n = 69) encountered at least one infection during the course of their disease. Respiratory-related infections were the most prevalent (76.2%), followed by urinary tract infections (10%) and instances of diarrhea (8.8%). Notably, gram-positive bacteria constituted the majority of identified causative organisms, accounting for 48.2% of isolated pathogens, while gram-negative bacteria comprised 37.9% of the isolated organisms. Most infections were observed either at the time of presentation or during the first month (40.5%). Overall mortality during the study period was 4.8% (n = 7). Infections contributed to 57.1% (n = 4 out of 7 deaths) of the mortality. Moreover, patients in advanced stages exhibited an elevated risk of infection at presentation. Infections remain a major cause of morbidity and mortality in patients with MM. Nearly half of MM patients experience an episode of infection during treatment.Gram-positive bacteria are the most common pathogens, with respiratory infections being the most common foci. Prompt identification and treatment of infections is essential, but can be challenging due to atypical or absent symptoms. Antibacterial prophylaxis is an important preventive strategy, but further research is needed to develop innovative approaches to infection prevention and targeted therapeutic interventions. We must strive to develop innovative approaches to infection prevention in MM patients. Also we need to advance our understanding of the interplay between infections and MM to improve quality of care and outcomes for these individuals. By addressing these challenges, we can aspire to offer MM patients a brighter and healthier future.

Symptomatic orbital metastasis as an initial presentation of adenocarcinoma lung: A case report and review of literature.

ABSTRACT: Orbital metastasis is a rare entity in oncology. With increasing awareness and advancement, patients with initial ocular presentation can be diagnosed and treated. Ocular metastasis is more common in breast cancer followed by lung cancer. Lung cancer with ocular presentation generally have poor prognosis because of difficult diagnosis, Vision impairment and delayed management. Here, we report one such case of 59 year old female presented with painful periorbital swelling in left eye for 3 months with no pulmonary symptoms. On evaluation, she was diagnosed as ocular metastasis with primary being lung adenocarcinoma. Through this case, we enlighten the epidemiology, presentation, clinical features and evaluation of such patients which might help clinicians in further management.

Clinical Profile and Outcome of Adult Classical Hodgkin's Lymphoma: Real World Single Centre Experience.

Hodgkin's lymphoma treatment outcomes have been the true success story of modern medicine. Various data from western as well as Indian studies are available for classical Hodgkin's lymphoma (cHL). Here we report treatment outcomes from a tertiary cancer care centre in Karnataka over a 5 year period. This was a retrospective review of cHL cases aged 15 years and above diagnosed between January 2015 and December 2019 at Kidwai Memorial Institute of Oncology, Bengaluru, Karnataka, India. The case files of the patients were retrieved and relevant data was collected. Two hundred patients of cHL were included in this study. Median age was 28 years with male to female ratio of 1.56:1. B symptoms were present in 58% cases. Mixed cellularity (46.5%) was the most common histological subtype. Majority patients had advanced stage at presentation (stage III/IV) (62.5%). Extranodal disease was present in 19.5% cases. GHSG early-favourable cases were 15.5%, early-unfavourable cases were 22.0%, while 62.5% were advanced cases. The most common chemotherapy regimen used was ABVD. Eighty-three (41.5%) patients received radiation therapy. Median follow-up was 34.2 months (range 4.1-67.8). The rates for complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD) were 84.5%, 8.5%, 5.0% and 2.0% respectively. PFS and OS rate at 6 years were 69.5% and 84.1% respectively. HL is one of the malignancies with high cure rate. The treatment outcome at our centre is comparable to western data and data from other tertiary centres from India.

Extranodal natural-killer/T-cell lymphoma, nasal type: An immunomorphological study from a regional cancer institute in India.

Introduction: Extranodal natural-killer/T-cell lymphoma, nasal type (ENKTL), is a rare, aggressive, predominantly extranodal non-Hodgkin lymphoma (NHL) of putative natural-killer (NK) cell and rarely T-cell origin, always associated with Epstein-Barr virus (EBV) infection and characterized by highly distinctive histopathological features with predilection for the upper aerodigestive tract. While the nasal cavity is the prototypical site, less frequently extranasal ENKTL can also occur. The objective of this case series is to study the immunomorphological features of ENKTL from a tertiary cancer centre as the data are sparse from India despite it being a distinct entity with characteristic clinicopathological features. Methods: We identified 11 cases of ENKTL from the departmental archives between January 2015 and June 2018. The clinicopathological and immunohistochemistry (IHC) findings of these tumors were analyzed. EBV encoded RNA (EBER) in situ hybridization (EBER-ISH) for EBV was done in eight cases. Results: The disease was more common in males (male: female ratio 1.8:1) with the mean age of 45 years (range 31-65 years). Sinonasal region was the most common site with 9 cases and skin and penis were involved in one case each. The patient with penile involvement on further investigations was found to have occult nasal involvement, Histomorphological features such as angiocentricity/angioinvasion was seen in seven cases (63.6%) and significant necrosis was present in all 11 cases (100%). All cases were uniformly positive for cytoplasmic CD3 and CD56 with high Ki67 proliferating index and EBER-ISH test for EBV was positive in all the eight cases. Conclusion: ENKTL is an aggressive NHL and should be differentiated from other T- and B-cell lymphomas as the prognosis and therapy differ. Nasal biopsies showing predominant necrosis and atypical lymphoid cells with angiocentricity must raise the suspicion of ENKTL and should be confirmed by immunomorphological and molecular studies.

Pre-phase strategy to mitigate first cycle effect in diffuse large B cell lymphoma.

CONTEXT: Treatment-related toxicities in DLBCL (diffuse large B cell lymphoma) patients are higher in the initial phase of treatment (first cycle effect). Implementation of pre-phase treatment before definitive chemotherapy had been shown to alleviate some of these side-effects in a non-randomized study conducted earlier in our institute (Lakshmaiah et. al., Eur J Haematol 100:644-8, 2018). AIMS: This study was aimed at validating the role of pre-phase treatment in newly diagnosed DLBCL patients. SETTINGS AND DESIGN: All newly diagnosed patients with DLBCL above the age of 18 years were evaluated for eligibility and prospectively enrolled. A single-arm prospective study was conducted at the Department of Medical Oncology, in our institute from July 2015 to December 2019. METHODS AND MATERIAL: Patients received vincristine and prednisolone as pre-phase treatment for 7 days after which definitive chemotherapy was instituted on day 1. They were followed up for 30 days post-first cycle chemotherapy. STATISTICAL ANALYSIS USED: Paired Student's t tests and Wilcoxon signed-ranks test were used for comparison of various clinical variables as appropriate. P value of less than 0.05 was considered significant. RESULTS: Among the 180 patients who were included in study, performance status improvement was noted in significant number of patients (p < 0.001). 38.4% achieved an ECOG (Eastern Cooperative Oncology Group) performance status of 0 post-pre-phase therapy. Febrile neutropenia was observed in 12.8% in the present cohort as compared to the historical non-pre-phase cohort (34%). CONCLUSIONS: Pre-phase therapy significantly improves the performance status and diminishes neutropenia rates in DLBCL patients.

Comparison Between CHOP and DAEPOCH with or Without Rituximab in Adult High Grade B Cell Lymphoma, Not Otherwise Specified; A Retrospective Study From a Tertiary Cancer Hospital in South India.

Lymphoma that on morphology appear blastoid or intermediate between DLBCL and BL but who lack myc and bcl-2 and/or bcl-6 rearrangements are grouped under high grade B-cell lymphoma, not otherwise specified (HGBL, NOS). Only a few studies have yet compared the outcome of HGBL, NOS treated with different chemo-immunotherapy regimens. HGBL, NOS patients were analyzed retrospectively, who were treated with CHOP or DAEPOCH regimens every 21 days for six cycles with or without rituximab. The primary clinical objective was progression free survival. One and two year PFS rates were 29.4% and 20.6% for the CHOP arm and, 65.2% and 47.8% for the DAEPOCH arm respectively. There was statistically significant difference in mean PFS between the arms (DAEPOCH vs CHOP: 19.7 months vs 12.8 months; HR = 0.44, p = 0.02, 95% CI: 0.22-0.88). One and two year OS rates were 91.1% and 20.5% for the CHOP arm and 95.6% and 60.8% for the DAEPOCH arm respectively. Mean OS was significantly better for DAEPOCH arm (28.1 months vs 20.7 months: HR = 0.43, p = 0.03, 95% CI: 0.20-0.92). Grade 3 and 4 hematological and non-hematological toxicities were more common in DAEPOCH arm. There were 2 treatment related deaths, 1 in each arm (4.3% for DAEPOCH vs 2.9% for CHOP). HGBL, NOS is a heterogeneous group of aggressive lymphoma associated with early relapse in nearly half of the cases. Intensive regimens like DAEPOCH is associated with improved outcome in terms of PFS and OS. Though toxicities are more with DAEPOCH, they are manageable and treatment related mortality is low.

Rapidly Progressing Plasma Cell Leukemia with Underlying Plasmablastic Morphology: A Rare Case Report of a 25-Year Old Male.

Multiple myeloma constitutes a wide spectrum of diseases, ranging from slow-growing monoclonal gammopathy of undetermined significance to rapidly progressing plasma cell leukemia. It is a very rarely diagnosed hematological malignancy in those less than 30 years of age. A 25-year-old male presented with complaints of fatigue and low-grade fever. On investigation, he was found to have bicytopeina and features of tumor lysis syndrome. Initially, this was thought to be indicative of acute leukemia. However, upon further analysis with bone marrow biopsy, serum protein electrophoresis, and immunofixation, it was determined that the patient had an IgG myeloma with plasmablastic morphology. It rapidly progressed and the peripheral smear started showing clusters of plasma cells suggesting a picture of plasma cell leukemia. The patient succumbed to this aggressive disease despite treatment. This case illustrates that myeloma should also be included in the differential diagnosis for young patients, especially the rare plasmablastic variant, which can be misdiagnosed as acute leukemia. The aggressive morphology also tends to show rapid progression to plasma cell leukemia, which has a poor prognosis.

Discordance in clinical versus pathological staging in breast cancer: Are we undermining the significance of accurate preoperative staging in the present era?

BACKGROUND: The present era of individualized treatment for breast cancer is influenced by the initial disease status including the anatomical extent, grade, and receptor status. An accurate preoperative staging is the basis of treatment planning and prognostication. Our study aims to determine the discordance between the preoperative clinical and the postoperative pathological stages of breast cancer patients. METHODOLOGY: The medical records of all non-metastatic breast cancer patients from January 2017 to December 2018 who underwent upfront surgery were reviewed. They were staged as per the eighth AJCC and the concordance between the clinical (c) and pathological T (tumor), N (nodal), and final AJCC stage was studied. A Chi-square test was used to determine factors that significantly correlate with disease discordance. RESULTS: A total of 307 breast cancer patients were analyzed. Among these, 43.3% were hormone receptor-positive, 30.6% were Her2 positive and 26% were triple-negative. Overall stage discordance was seen in 48.5% (n = 149) patients (upstaging in 22.1%, downstaging in 26.4%). The discordance rate was 48.9% for T stage (cT versus pT) and 57.4% for N stage (cN versus pN). Among patients with clinically node-negative disease, 53.4% were found to have positive nodes on histopathology, while 27.2% had vice versa. Overall, the factors associated with upstaging were ER-positive, Her2 positive and triple-negative status (all p < 0.05), while none of the factors showed significant association with downstaging. CONCLUSIONS: About half of breast cancer patients had discordance between clinical and pathological staging with higher discordance in the nodal stage. This changes the disease prognosis, and may also affect the offered surgical treatment and radiotherapy. Thus highlighting the need for a precise pre-operative staging. Also, this information will aid clinicians in discussions with patients, keeping in mind the likelihood of change in disease staging and management.

A Pilot Study on the Addition of Tramadol or Eutectic Mixture of Local Anesthetics (Prilocaine Plus Lignocaine) to Local Lignocaine Infiltration for Prevention of Bone Marrow Aspiration/Biopsy Associated Pain.

Objectives Bone marrow aspiration although being a common procedure is associated with significant pain and its reduction remains an unmet need. We evaluated the use of tramadol and eutectic mixture of local anesthetics (prilocaine plus lignocaine) (EMLA) for reducing the severity of pain. Materials and Methods In this pilot study, we compared the addition of either tramadol 50 mg per oral (T) or EMLA local application (E) or no intervention (L) in addition to the usual procedure of local infiltration with lignocaine 2% before bone marrow aspiration and biopsy (BMAB) in adults suspected/confirmed with malignancy. Both, tramadol and EMLA were administered 1 hour prior to the procedure. Primary end point was reduction in pain intensity with these interventions compared with local infiltration alone. Pain was assessed using numerical FACES pain scale, a visual analogue scale. Secondary end points were to see the effect on pre procedure apprehension and to find out the other factors associated with increased pain related to the procedure. Statistical Analysis and Results A total of 300 patients were included in the study, 100 each in tramadol (T), EMLA (E), and only lignocaine local infiltration (L) arms, respectively. The mean pain intensity on the visual scale was significantly lower in the tramadol arm (T, E, L-3.4, 4.4, 4.7, respectively) ( p < 0.0005). There was a significant reduction in percentage of patients who experienced moderate/severe pain (four or more) in the tramadol arm (T, E, L-45, 77, 82%, respectively) ( p < 0.0005). Duration of procedure >10 minutes, body mass index >30, ECOG (Eastern Oncology Group) performance status ≥3, and age >50 years were positively correlated with more pain. Leukemia patients experienced significantly more pain compared with patients with lymphoma and other solid malignancies. Tramadol was well tolerated. No significant effect on pre-procedure apprehension was noted in any of the arms. Conclusion Tramadol appears to have a preventive effect on bone marrow aspiration/biopsy-associated pain and appears to be well tolerated, whereas EMLA was not associated with such an effect. Larger studies may be done to ascertain the same.

Follicular Lymphoma in Young Adults: Study from a Regional Cancer Center in South India.

Objective Follicular lymphoma (FL) is a disease of the elderly. It is postulated that younger patients have distinct tumor biology and treatment outcomes. Various lymphoma groups across the world have studied this to understand if young adults (YAs) need a different treatment approach. Our study fills the void in data from an Asian country on YA population with FL. Patients and Methods We retrospectively analyzed young patients (age ≤40 years) diagnosed with FL at our center from 2012 to 2018. Their disease characteristics, treatment details, and outcomes were studied to examine any association between various parameters and survival. Results There were 28 young FL patients included in our study that constituted 14.6% of FL cases (males: 53.5% and females: 46.5%). The median age at diagnosis was 36.5 years. Most of the patients presented in an advanced stage, 57% had extranodal involvement, and 39.3% had bone marrow involvement at the time of presentation. The most common chemotherapy regimen used was cyclophosphamide, vincristine, and prednisone. Half of them received chemoimmunotherapy and only 18% continued rituximab as maintenance therapy. The overall response rate was 92.9% ( n = 26), and the remaining two patients had progressive disease while on treatment. The median progression free survival (PFS) was 6.1 years and median overall survival (OS) was not reached. On univariate analysis, extranodal disease was associated with a lower PFS ( p = 0.06) and low hemoglobin showed a significant association with OS ( p = 0.005). On multivariate analysis, none of the factors showed a significant association with survival. Conclusion Most YAs present with advanced disease with a good response to treatment and favorable outcomes.

Metastatic hormone receptor-positive breast cancer in CDK 4/6 era: An outcome audit.

BACKGROUND: The treatment landscape of metastatic hormone receptor (HR) positive breast cancer has been changed in recent years. Availability of CDK 4/6 inhibitor and other hormone therapy has changed the treatment algorithm for these patient, we retrospectively analyzed our metastatic HR positive breast cancer patients. MATERIALS AND METHODS: In this study, we retrospectively analyzed the case records of hr positive metastatic breast cancer patient treated at department of medical oncology from October 2016 to September 2018. Demographical characteristics, site of metastasis, objective response and clinical benefit response and toxicity profile were analyzed. RESULTS: We treated a total of 178 patients of MBC with HT at our center during the study period. One hundred fifty-two patients received HT alone (control group) and 26 patients received HT and CDK 4/6 inhibitor (study group). The median age of patients was 56 and 58 years in the control group and study group. The ORR was 41.7 versus 57.9 (95% CI [1.01-2.56]), and the CBR was 66.1% versus 78.9%; (CI [1.18-3.56]) (P < 0.05) of the patients in control and study groups, respectively. CONCLUSIONS: Among patients with HR-positive, advanced breast cancer, hormone therapy is efficacious addition of CDK 4/6 inhibitor improve the efficacy with tolerable side effects.

Primary mucinous carcinomas of the lung: Clinical characteristics and treatment outcomes.

INTRODUCTION: Invasive mucinous adenocarcinoma (IMA) of the lung is a distinct histologic variant of adenocarcinomas comprising about 2%-10% of lung adenocarcinomas. A large proportion of IMAs carry KRAS mutations and only rarely epidermal growth factor receptor (EGFR) mutations or ALK/ROS translocations; thus, most cases are not amenable for targeted therapy at present. This study was conducted to elicit the unique clinicopathological characteristics of IMA. MATERIALS AND METHODS: Medical records of patients diagnosed with IMA by needle biopsy at Kidwai Cancer Institute, Bangalore, from 2013 to 2018, were retrieved and reviewed. Statistical analysis was performed using SPSS version 23.0 (IBM Corp., Armonk, NY, USA). RESULTS: Four hundred and ninety cases of needle biopsy of the lung were diagonosed at our institute between January 2013 and December 2018. Nine cases (1.8%) were diagnosed as IMA. The median age of presentation was 59 years. Six (66.7%) were current smokers with pack-year > 20. Three (33.3%) of the cases were initially misdiagnosed as pneumonia in view of computed tomography findings. The lung was the most common site of metastasis (77.8%). Serum Carcinoembryonic Antigen (CEA) was elevated in six cases (66.7%). None of the cases had any driver mutations in EGFR gene or ALK and ROS1 translocations. All cases were treated with pemetrexed-carboplatin doublet followed by pemetrexed maintenance till progression. The median progression-free survival (PFS) was 15 months (range: 5-18 months). Docetaxel was given as the second-line chemotherapy in all progressed patients. Best response noted was stable disease, seen in 4 (57.1%) cases. The median PFS for docetaxel was 6 months (range: 3-8 months). The median overall survival was 22 months (range: 9-27 months). Patients with initially raised CEA at progression had a serial rise in serum CEA. CONCLUSIONS: IMA is rarely diagnosed on needle biopsies due to insufficient tissue. They mimic pneumonia on imaging, thus delaying diagnosis. EGFR mutations, ALK, and ROS1 translocations are usually negative making them ineligible for tyrosine kinase inhibitors. Response to chemotherapy is modest.

Socioeconomic and administrative factors associated with treatment delay of esophageal and gastric carcinoma: Prospective study from a tertiary care centre in a developing country.

This study was aimed to analyze the spectrum of time intervals, from the onset of symptoms to the commencement of treatment in esophagogastric cancers. Factors influencing these time delays and correlation between these time points with variables including socioeconomic strata, educational level, histopathology, location of tumor and the initial modality of treatment were assessed. STUDY SETTING AND METHODS: A prospective analysis of patients with esophagogastric cancer presenting to a single tertiary care unit over a period of 12 months was performed. Histopathology other than adenocarcinoma and squamous cell were excluded. RESULTS: 202 patients were enrolled in the study. Most patients presented with advanced disease, i.e. 91.5 % of esophageal and 90 % of gastric malignancies belonged to either stage 3 or stage 4 as per American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) staging system. The median delay from the appearance of the first symptoms to initiation of treatment was 15 weeks (range 4-64). Patient related factors contributed to a significant delay [median of 5 weeks (range 1-24)]. Administrative factors were responsible for median delay of 3 weeks (range 0.5-20). Curative multimodality treatment was administered in 62.5 % of patients. Significant longer delay was influenced by socioeconomic strata, educational level, evaluation by non-specialist (p < 0.05). No relationship was noted between histopathology, location of tumor or initial modality of treatment. CONCLUSIONS: Delays in our setting is much more than that is seen in Western and even some Asian countries. An important component of delay is administrative related factors. These may be intervened at the hospital level compared to other factors which may need long term community oriented approaches.

Follicular lymphoma transforming to DLBCL and reverting back to follicular lymphoma at relapse-a case report.

BACKGROUND: Transformation of low-grade follicular lymphoma to high-grade diffuse large B cell lymphoma (DLBCL) is known. However, the opposite is not commonly reported. In this report, we present a case of follicular lymphoma that underwent transformation to DLBCL. Three years after treatment for histologic transformation, the patient presented again with low-grade follicular lymphoma at the same site which is unusual in the natural history of follicular lymphoma. CASE PRESENTATION: A 50-year-old female patient presented to us with complaints of slowly progressing swelling in the neck on the left side for a duration of 1 year. Past history of the patient revealed a diagnosis of follicular lymphoma in 2004 for which the patient had taken prednisolone and chlorambucil. Details of staging were not available with the patient. After a complete work-up, she was diagnosed as DLBCL, stage IIIE. She was treated with 6 cycles of CHOP regimen. She had very good response to chemotherapy. However, she defaulted and was lost to follow-up. She presented again after 3 years with history of painless progressive swelling in the right side of the neck for the last 1 year. Examination revealed cervical lymph nodes and ascites. This time, a repeat biopsy and immunohistochemistry was suggestive of follicular lymphoma. In view of significant ascites, she was started on chemotherapy with CVP regimen. After 6 cycles, she has good partial response and resolution of ascites. She is currently on follow-up. CONCLUSIONS: We have presented a case of FL that has transformed to DLBCL after 10 years of diagnosis. After HT, she was treated with CHOP chemotherapy and the patient relapsed again after 3 years with follicular lymphoma histology. This case highlights the unique and varied natural history of follicular lymphoma that may be attributed to different subclones of malignant cells that may have arisen from a common progenitor FL cell and differential effect of chemotherapy on these subclones.

CML in Elderly: Does Age Matter?

The median age of diagnosis for chronic myeloid leukemia (CML) in India is 35 years on the contrary to western literature which is 47 years. The outcome of the elderly patient in CML TKI era is not reported from the Indian population. However, Western literature suggests that use of TKI alleviate the adverse impact of age in outcomes of CML. This study was carried out to analyze the clinical profile and outcome of elderly, in comparison with younger patients with CML. We retrospectively analyzed CML patients treated at our department from January 2008 to December 2017. The data cutoff date was December 2018. The cohorts of 712 patients were divided into two groups. Patients belonging to the age group of ≥ 60 years were classified as the study group and those who were 18-60 years were used as controls. Patient's clinical history, examination and milestones in terms of achieving hematological, molecular responses and toxicity profile were also recorded. The total of 712 patients, 52 patients in the study group and 660 patients in the control group were treated during the study period. The study group was having more co-morbidities than the control group (15.3% vs. 4.5%). Patients having high-risk EUTOS score were similar in both groups (38.4% vs. 37.6%). The patients presented in blast phase were higher in the study group as compared to control group (9.6% vs. 6.36%) but the differences were not statistically significant. Rates of achieving a hematological response at 3 months (85.1% vs. 86.89%) and the major molecular response at 18 months (54.3% vs. 60.16%) were almost similar in both groups. However, hematological toxicity, muscle cramps and gastritis were reported more in elderly patients. The outcome of CML patients in TKI era do not differ in elderly patients. However, toxicity profile was not significantly inferior in elderly patients.

Detection of clinically relevant epidermal growth factor receptor pathway mutations in circulating cell-free tumor DNA using next generation sequencing in squamous cell carcinoma lung.

BACKGROUND: Limited repertoires of targets are available in the management of squamous cell carcinoma lung. In this study, we analyzed epidermal growth factor receptor (EGFR), RAS, BRAF mutations in lung cancer patients of squamous cell histology using next-generation sequencing (NGS) on the circulating cell-free DNA (cf-DNA). MATERIALS AND METHODS: In this prospective observational study, patients with squamous cell carcinoma lung, either newly diagnosed or having a progressive disease on prior therapy were eligible. Cf-DNA was extracted from peripheral blood and analyzed for EGFR, KRAS, NRAS, and BRAF mutations using NGS. RESULTS: Sixteen patients were enrolled over a period of 1 month. The mean cf-DNA quantity extracted from the plasma was 96.5 ng (range, 15-200 ng). Eight clinically relevant mutations in the EGFR pathway were identified. These include Exon 21 mutations in 4 patients, Exon 20 mutation in onepatient, complex mutations with coexisting Exon 21 and Exon18 in one patient and KRAS Exon 2 mutations in two patients. CONCLUSION: cf-DNA is a minimally invasive technique for detection of clinically relevant mutations in lung cancer patients. The use of novel advanced techniques such as NGS may help in detecting EGFR pathway mutations in patients with squamous cell carcinoma lung.

Modified Epirubicin, cisplatin, and 5-FU regimen as first-line chemotherapy in metastatic gastric or gastroesophageal junction adenocarcinoma: A Phase II study.

BACKGROUND: Epirubicin, cisplatin, and 5-FU (ECF) is one of the most commonly used first-line chemotherapy regimens in metastatic gastric cancer. However, due to protracted infusion schedule, need for special infusion pumps, and catheter-related complications, the practical utility and acceptability of standard ECF regimen are limited, particularly in resource-constrained settings including India. MATERIALS AND METHODS: In the present study, we have used a more convenient modification of the standard ECF protocol (using 5 days intravenous infusion of 5-FU at a dose of 750 mg/m2/day, given over 6 h through a peripheral venous line), in Indian patients with metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma. The primary endpoint was overall survival (OS). The secondary endpoints were overall response rate (ORR), progression-free survival (PFS), and toxicity profile. RESULTS: Between January 2014 and December 2017, 107 patients were assigned and treated with this modified ECF regimen. The median age was 52 years (range, 34-62); 66.3% were males and 36.5% of the patients had ≥ 3 metastatic disease site involvement at baseline. Dose reductions due to toxicity were required in 14.9% of the patients. The ORR was 32.7%; median PFS and OS were 5.9 months (95% confidence interval [CI]: 4.7-6.9) and 10.4 months (95% CI: 8.4-11.8), respectively. Both the hematological and nonhematological toxicities were manageable, and there was no toxicity-related death. The most frequent Grade 3-4 adverse events were neutropenia (18.7%), febrile neutropenia (13.1%), mucositis (5.6%), and diarrhea (5.6%). CONCLUSIONS: In the present study, the modified ECF regimen demonstrated significant efficacy with an acceptable toxicity profile in Indian patients with metastatic gastric and GEJ adenocarcinoma. The survival outcomes of this modified schedule were comparable with those of the standard ECF regimen, as reported earlier. Clearly, this modified and more convenient ECF protocol should be explored and validated through large prospective randomized trials.

Every distant deposit is not a metastasis: Synchronous primaries do exist.

BACKGROUND: Synchronous occurrence of two malignant tumors is a rare event. With increasing use of sophisticated imaging modalities for staging, synchronous multiple tumors are more commonly detected now. Assuming the second primary malignancy as metastasis will change the intent of treatment from curative to palliative, greater awareness among oncologists is of paramount importance. This study is an example where thorough clinical examination and proper judgment resulted in correct diagnosis and appropriate treatment. MATERIALS AND METHODS: This is a prospective descriptive study. Patients diagnosed with synchronous primary tumors from January 2016 to November 2017 at our center were reviewed. RESULTS: Ten cases of synchronous primary malignancies were detected during this period. A total of 20 primary tumors were diagnosed. Lung carcinoma and gastrointestinal malignancies were the most common (five patients each). The median age was 59.5 years. Seven patients were male. Second primary tumor was suspected in four patients during clinical examination, while in six patients it was suspected on imaging. Even in the presence of two primary tumors, three patients were treated with curative intent. CONCLUSION: Possibility of synchronous second primary malignancy should always be kept whenever a distant deposit is detected at an unusual site. Histopathological evaluation of the lesion before assuming a metastasis will lead to accurate diagnosis, staging, and appropriate treatment.

Primary gastrointestinal diffuse large B-cell lymphoma: A prospective study from South India.

BACKGROUND: Gastrointestinal tract (GIT) is the most common extranodal site for non-Hodgkin's lymphoma (NHL) and constitutes about 10%-15% of all NHL. This was a prospective study to evaluate the epidemiological, clinicopathological characteristics, and treatment outcome of primary GIT diffuse large B-cell lymphoma (PGIL). MATERIALS AND METHODS: Newly diagnosed patients of PGIL with DLBCL histology were eligible. Lugano staging system was used. All patients were treated with prephase treatment (1 mg vincristine and 100 mg prednisolone) followed by CHOP-based chemotherapy (with or without rituximab) as definitive treatment. RESULTS: A total of 21 patients of PGIL were diagnosed. The median age was 46 years (range: 27-69 years) with male:female ratio of 2:1. Dull aching abdominal pain was the most common presenting complaint. Stomach was the most common site involved (52.4%, n = 11) followed by the colon (23.8%, n = 5). The estimated median survival in patients with Stage IV disease was significantly lower as compared to patients with localized disease (Stage I and II) (6.23 months vs. 23.4 months; P = 0.04). Patients, who did not achieve complete response (CR), had 15.5 times higher risk of death, as compared to those who achieved CR (P = 0.01). CONCLUSIONS: Stomach was the most common site for PGIL. Localized disease and CR after first-line chemotherapy were associated with better survival. A higher cost of rituximab was the prohibitive factor for cure in these patients.
