Introduction: Plasmablastic lymphoma (PBL) is a rare and aggressive type of mature B-cell lymphoma, which is usually associated with HIV infection. The most common site of PBL is the oral cavity. Involvement of the gastrointestinal (GI) tract is rare, and literature is limited to few case reports and case series.Aims: To retrospectively analyze the presentation, clinical findings, and outcome of patients presenting to our institute with a diagnosis of PBL involving the GI tract.Materials and Methods: A retrospective observational study was conducted at our institute from February 2008 to January 2015 on consecutive patients presenting with PBL involving the GI tract. The data were compared to various case reports and series published in peer-reviewed journals.Results: There were four patients diagnosed with PBL of the GI tract; three male and one female. The location of involvement was in the stomach, ileocecal junction, ascending colon, and rectum. Only one patient was HIV-positive and was on combination antiretroviral therapy since 2 years. Among the three immunocompetent patients, only one survived with therapy; however, the patient relapsed within 6 months of completion of treatment.Conclusion: PBL was seen to have a uniformly aggressive clinical course with poor outcomes even with optimal treatment. The prognosis of immunocompetent patients appears to be worse than that of HIV-AIDS patients. Although the most common histologies seen with GI lymphomas are mucosa-associated lymphoid tissue type lymphomas or diffuse large B-cell lymphoma, rarer and more aggressive histologies like PBL need to be kept in mind.

Head and neck squamous cell carcinoma (HNSCC) is now the seventh most common cancer worldwide. The median overall survival for patients with recurrent and/or metastatic (R/M) HNSCC remains <1 year despite modern systemic chemotherapy and targeted agents. Palliative systemic therapy for patients with R/M HNSCC typically includes a platinum-based doublet, with an understanding that the increase in efficacy compared with single agents is primarily related to improved response rate, and not survival. Till date, the only systemic therapy regimen to demonstrate survival superiority over platinum-5-fluorouracil (5-FU) doublet is platinum, FU, and cetuximab. Epidermal growth factor receptor inhibitors, including monoclonal antibodies and tyrosine kinase inhibitors, have achieved only a modest success in R/M HNSCC. Immunotherapy represents an attractive treatment option for R/M HNSCC, with encouraging preliminary data from studies involving immune checkpoint inhibitors (e.g., pembrolizumab, nivolumab) and toll-like receptor agonists (e.g., motolimod). Given the poor prognosis of R/M HNSCC, enrollment of patients into clinical trials to investigate novel systemic agents, is necessary for further improvement of oncologic outcomes in this patient population.

- Abstract
Radioactive iodine (RAI) therapy plays an important role in the management of thyroid malignancies. Leukemia is a very rare complication of radioactive therapy. There are very few case reports with doses below 100 mCi causing leukemia. We report a case of papillary carcinoma of the thyroid treated with 80 mCi RAI who later developed acute myeloid leukemia. Thus, all patients with thyroid carcinoma treated with RAI should undergo periodic hematological examinations irrespective of RAI dose. [ABSTRACT FROM AUTHOR]

- Abstract
L. K. Rajeev Background 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., Competing Interests: Conflict of Interest None declared., (MedIntel Services Pvt Ltd.

- Abstract
Presence of additional copies of Philadelphia chromosome (Ph) is characteristic of chronic myeloid leukemia in blast crisis, very rarely observed in de novo acute lymphoblastic leukemia (ALL). Ph positive (Ph+ve) ALL and CML in lymphoid blast crisis (CML-LBC) are biologically different with divergent clinical course. Double Ph+ve ALL has little data available as to its incidence and prognostic significance. We studied five cases of Ph+ve precursor B-cell ALL having an extra copy of Ph chromosome with regard to their clinical and laboratory features. An extensive review of literature was done on prognostic significance and molecular aspects of double Ph in ALL. The study confirms that double Ph was a rare phenomenon in precursor B-cell ALL. It is observed that molecular basis of double Ph positive ALL is less understood compared to CML in blast crisis. The study highlights fundamental role of cytogenetic and molecular studies in diagnosis and management of these patients. Long-term follow-up studies on a larger group of patients are required to understand the prognostic impact of extra Ph in Ph+ve ALL, which is usually resistant to standard chemotherapeutic regimen and often requiring bone marrow transplantation., Supplementary Information: The online version contains supplementary material available at 10.1007/s12288-022-01525-1., Competing Interests: Conflict of interestThe authors have no conflicts of interest to declare that are relevant to the content of this article., (© Indian Society of Hematology and Blood Transfusion 2022.)

- Abstract
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., (Copyright © 2022 Tehran University of Medical Sciences.)

- Abstract
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., Competing Interests: Conflict of interestThe authors declare that there are no conflicts of interest., (© Indian Society of Hematology and Blood Transfusion 2021.)

- Abstract
This multicenter, double-blind, randomized study compared the efficacy, pharmacokinetics (PKs)/pharmacodynamics (PDs), safety and immunogenicity profile of RTXM83 vs. reference rituximab (R-rituximab), both with CHOP, as first-line treatment of diffuse large B-cell lymphoma (DLBCL). A total of 272 patients <65 years of age, with good prognosis (136 per arm) were randomized (1:1) to receive six cycles of either RTXM83 or R-rituximab. The primary efficacy endpoint was achieved (overall response rate of 83.6% for RTXM83 and 82.9% for R-rituximab) with a difference 0.7% between arms (95%CI: [-8.77% to 10.17%]) fulfilling the predefined non-inferiority margin (-13%). Similar number of patients reported at least one adverse event (AE) (131 per arm) or one serious AE (47 with RTXM83 and 45 with R-rituximab). Anti-drug antibody development was comparable between the arms. PK/PD secondary endpoint results support similarity between the compounds. RTXM83 exhibits non-inferior efficacy and similar safety/immunogenicity to R-rituximab, being an accessible alternative for the treatment of patients with previously untreated DLBCL.

- Abstract
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., Competing Interests: There are no conflicts of interest., (Copyright: © 2019 The South Asian Journal of Cancer.)

- Abstract
Background: Lapatinib (L) plus trastuzumab (T) with weekly paclitaxel significantly increased the pathologic complete response (pCR) rate compared with the anti-human epidermal growth factor receptor 2 (HER2) agent alone plus paclitaxel. The event-free survival (EFS) and overall survival (OS) by the treatment arms L + T vs. T and L vs. T and the relationship between pCR and EFS/OS both in the whole study population and according to hormone receptor-negative and hormone receptor-positive cohorts after a median follow-up of 6.7 years were assessed., Patients and Methods: Four hundred fifty-five patients with HER2-positive early breast cancer randomly received L 1500 mg/day (n = 154), T (common dose, n = 149) or L 1000 mg/day plus T (n = 152) for 6 weeks, followed by the assigned anti-HER2 treatment combined with paclitaxel weekly × 12. After surgery, patients received 3 cycles of fluorouracil, epirubicin and cyclophosphamide. The primary end-point was pCR (ypT0/is; for current analysis, it is ypT0/is ypN0), and the secondary end-points were EFS and OS., Results: Six-year EFS rates were 67%, 67% and 74% with L, T and L + T, respectively (L vs T: hazard ratio [HR], 0.98 [95% confidence interval {CI}, 0.64-1.51; P = .93]; L + T vs T: HR, 0.81 [95% CI, 0.52-1.26; P = .35]). Six-Year OS rates were 82%, 79% and 85% for L, T and L + T, respectively (L vs T: HR, 0.85 [95% CI, 0.49-1.46; P = .56]; L + T vs T: HR, 0.72 [95% CI, 0.41-1.27; P = .26]). In landmark analyses, patients with a pCR had a significantly higher 6-year EFS (77% and 65%) and OS (89% and 77%) compared with those without a pCR for both overall and the hormone receptor-negative cohort., Conclusion: Achieving a pCR is important in HER2-positive disease and translates into better long-term outcome with regard to EFS and OS., (Copyright © 2019 Elsevier Ltd.

- Abstract
Elderly patients with acute myeloid leukemia have a poor prognosis. Data from developing countries is sparse in the literature. In this retrospective study, 402 patients aged ≥ 60 years, diagnosed between Jan 2013 and Dec 2017, were analyzed for treatment patterns and survival. Median age of the whole cohort was 68 years (range 61-84). A total of 213 patients (53.3%) refused care; 188 patients (46.7%) received either BSC, LDAC, or HMA. Survival (in months) was 3.9, 6.4, and 1.2 with LDAC, HMA, and BSC, respectively. One-year survival was 17.2% and 6% with HMA and LDAC, respectively (P = 0.02). Overall response rate (ORR) did not differ between HMA and LDAC group (p = 0.12). HMA cohort had higher complete responses (20.6% vs 7.4%, p = 0.02), stable disease (32.7% vs 13.5%, p = 0.02), and transfusion independence (TI) (46.5% vs 22.2%, p = 0.01). Survival did not differ between the groups if the patients achieved ORR (12.3 vs 9.8 p = 0.2) or TI (11.6 vs 6.4 p = 0.2). Stable disease with HMA led to longer survival (8.1 vs 5.3 p = 0.01). HMAs were more effective than LDAC irrespective of cytogenetic risk category and blasts, of note HMAs improved survival of poor risk patients (5.6 vs 2.9 p = 0.004). HMA treatment (HR = 0.48; 95% 0.29-0.79, p = 0.004) and transfusion independence (HR = 0.2; 95% 0.1-0.3, p = 0.0001) predicted survival in multivariate analysis. Neutropenia and febrile neutropenia were frequent in HMA. Thrombocytopenia was the common adverse event with LDAC. Novel and cost-effective drugs are essential to improve the prognosis of these patients.

- Abstract
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/m
2 /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., Competing Interests: There are no conflicts of interest.- Published

- Abstract
Background: Thymic epithelial tumors (TET) are the most common tumors of the anterior mediastinum. Patients with advanced/metastatic disease are usually treated with palliative chemotherapy (CT). Unfortunately, even though various palliative CT regimens have been used for long time, there is a real scarcity of published Indian data regarding the experience of palliative CT in metastatic TET (mTET)., Materials and Methods: This is a retrospective analysis of mTET patients treated between January 2010 and September 2017. Patients who received at least three cycles of first-line palliative CT were included for analysis of response rates, toxicity, and survival and prognostic factors., Results: Of the 49 mTET patients, 27 (55.1%) were males. The median age at diagnosis was 52 years (range: 25-65). Eighteen patients (36.7%) had Masaoka Stage IVa disease, and the rest of the patients had IVb disease. The most common site of metastasis was pleuropericardium (n = 18), followed by lungs (n = 16) and lymph nodes (n = 9). The median progression-free survival and overall survival (OS) were 11.2 months (95% confidence interval [CI], 8.7-13.6) and 20.2 months (95% CI, 17.1-22.8), respectively, for the whole cohort (n = 49). The median OS of patients with Stage IVa disease was significantly better than that of the patients with Stage IVb disease (log-rank P = 0.000). Moreover, the "responders" to first-line CT had a significantly better median OS than the "nonresponders" (log-rank P = 0.000). Various first-line palliative CT regimens were well tolerated in our patients., Conclusion: Adriamycin Cisplatin Vincristine Cyclophosphamide (ADOC), Cyclophosphamide Adriamycin Cisplatin, and paclitaxel + carboplatin all are viable first-line palliative CT options for mTET and showed a comparable survival in Indian patients. The present study suggested that "responders" to first-line CT and those with Stage IVa disease might have a better survival than "nonresponders" and those with Stage IVb disease, respectively., Competing Interests: None

- Abstract
Background: Health-related quality of life (HRQOL) is an important oncologic end point for upper gastrointestinal malignancies. Unfortunately, till date, there is no published prospective data from India, comparing the HRQOL parameters between first-line chemotherapy regimens in advanced/metastatic gastric cancer., Materials and Methods: The present study aimed to compare the HRQOL of first-line systemic chemotherapy with epirubicin, cisplatin plus 5-FU (ECF) and docetaxel, cisplatin plus 5-FU (DCF) regimens in patients with locally advanced inoperable or metastatic gastric or gastro-esophageal junction adenocarcinoma. The secondary end points were overall response rate, progression-free survival (PFS), overall survival (OS), and toxicity profile., Results: Between December 2014 and December 2016, 65 patients were treated with ECF ( n = 34) or DCF ( n = 31) regimen. The baseline HRQOL scores were comparable between the two study groups, with the exception of significantly poor pain and sleep difficulties symptom score in the DCF group. After three cycles of treatment, both the groups showed improvements in most of the quality of life (QOL) parameters including global QOL score, compared with their baseline status. After six cycles of chemotherapy, the ECF group showed nonsignificant deterioration for most of the QOL parameters; but on the contrary, the DCF group maintained improved scores for most of the QOL parameters. The median survival until a definitive deterioration of global QOL score was significantly better in the DCF arm in comparison to the ECF arm (7.1 vs. 5.6 months, respectively, P = 0.000). The median OS was 9.2 months with ECF and 12.5 months with DCF regimen ( P = 0.000), while median PFS was 5.7 and 7.4 months with ECF and DCF regimens, respectively ( P = 0.002)., Conclusions: This prospective study highlighted a better impact of DCF chemotherapy on the HRQOL of patients with advanced/metastatic gastric cancer and showed the importance of QOL assessments in clinical trials to complement the risk-benefit judgment., Competing Interests: There are no conflicts of interest.

- Abstract
Introduction: Diffuse large B-cell lymphoma (DLBCL) is an aggressive lymphoma whose outcomes have significantly improved with rituximab in addition to anthracycline-based chemotherapy., Objective: This study aimed to study the epidemiology, treatment, and outcomes of patients with DLBCL., Materials and Methods: A total of 526 patients diagnosed with DLBCL between 2006 and 2015 were retrospectively analyzed., Results: The median age was 50 years with a male preponderance. Two hundred and twenty-three (42.39%) patients presented with B symptoms. A total of 53 (10.07%) patients presented with bulky disease and 202 (31.40%) with extranodal disease. The most common extranodal sites involved were the stomach (20.79%) and the bone marrow (10.89%). Bone marrow involvement was seen in only 22 (4.18%) cases. The distribution of patients presenting in low, low-intermediate, high-intermediate, and high-risk International Prognostic Index (IPI) were 148 (28.13%), 191 (36.31%), 124 (23.57%), and 63 (11.97%), respectively. The median survival of the entire cohort was 22 months. Survival of patients that compared the two groups with respect to the IPI - one having clubbed patients in low and low/intermediate risk and the other clubbing high/intermediate and high risk showed significantly improved survival in the lower risk groups - 24 versus 18 months (P = 0). The survival of those who received chemoimmunotherapy i.e R - CHOP was significantly better than those who received chemotherapy (CHOP) alone - 33 versus 21 months (P = 2.22e-16)., Conclusions: DLBCL is one of the most common lymphomas seen in our daily practice. Outcomes are significantly inferior compared to western countries. Biological and patient-related factors such as nongerminal center B subtype, higher extranodal involvement, and poor tolerability to treatment could contribute to inferior outcomes., Competing Interests: There are no conflicts of interest

- Abstract
Background: Colorectal cancer (CRC) is considered a disease of elderly. There has been a steady decrease in the incidence in those aged >50 years, with an alarming increase noted in adults aged <50 years., Subjects and Methods: We retrospectively analyzed 89 patients diagnosed with CRC aged <40 years between the years 2010 and 2014. Their clinical profile, treatment, and outcomes were studied., Results: The median age was 33 years with a male preponderance (56.2%). Most common symptoms were lower gastrointestinal bleed (48.3%) followed by abdominal pain (46.1%). Most common sites were rectum (50.6%) followed by colon. Histology in all was adenocarcinoma. Most tumors were moderately differentiated (54%) and were stage 4 (36%). Most common sites of metastases were liver (46.9%) followed by peritoneum and ovaries. Majority underwent surgery with adjuvant chemotherapy, with/without radiotherapy. Chemotherapy was administered in 70 patients, majority receiving FOLFOX-4 regimen (88.6%). Median survival was 23 months. Survival in early stage[1],[2] was significantly higher than in advanced stages (3 and above), 34 and 19 months ( P = 0.0287), in those aged >40 years compared to <40-35 versus 23 months ( P = 0.0029), nonmetastatic compared to metastatic disease - 26 versus 14 months ( P = 0.00196), and females compared to males - 26 and 18 months ( P = 0.0242). There was no significant difference in survival with respect to tumor grade or site of metastases (hepatic versus extrahepatic)., Conclusions: Colorectal carcinoma in young seems to be an emerging problem in India. Any young patient presenting with symptoms suggestive of a colonic malignancy should be evaluated promptly and treated aggressively., Competing Interests: There are no conflicts of interest.

- Abstract
Objectives: The present study aimed to investigate the efficacy, toxicity, and impact of induction chemotherapy (IC) in technically unresectable T4a oral cavity squamous cell cancers (OSCCs)., Materials and Methods: Patients diagnosed with technically unresectable locally advanced T4a OSCC from January 2013 and November 2016 at our center, who received 2-3 cycles of IC and then assessed for resectability, were reviewed retrospectively. Patients' profile, response rates and toxicity of IC, resectability status, and overall survival (OS) were evaluated. Statistical analyses were performed using SPSS version 17.0 for Windows (SPSS Inc., Chicago, IL, USA)., Results: Totally 80 patients received IC, and of them 58 (72.5%) were males. Median age at diagnosis was 44 years (range, 34-62 years). All our patients received IC with doublet regimen. Majority of the patients had buccal mucosa cancers (73.8%), followed by gingivobuccal complex (21.2%) and oral tongue (5%) primaries. After IC, partial response was achieved in 17 (21.3%) patients, stable disease in 49 (61.3%) patients and disease progression was noted in 14 (17.4%) patients. Post-IC, resectability was achieved in 19 (23.8%) of 80 patients, but 4 of them did not undergo surgery due to logistic and personal reasons. The median OS of patients who underwent surgery followed by adjuvant local therapy ( n = 15) was 16.9 months (95% CI: 15.2-19.8 months) and for those treated with nonsurgical local therapy ( n = 65) was 8.8 months (95% CI: 6.8-10.6 months) (log-rank P = 0.000)., Conclusions: IC had a manageable toxicity profile and achieved resectability in 23.8% of our patients with technically unresectable T4a OSCC. Patients underwent resection had a significantly better median OS than those who received nonsurgical local treatment., Competing Interests: There are no conflicts of interest.

- Abstract
Context: Carcinoma cervix is a leading cause of cancer in Indian females where 15%-60% of the cases eventually metastasize. Bone only metastasis is rare, and data on its response and survival with systemic therapy as compared to other visceral metastasis are limited., Settings and Design: The study design was a retrospective analysis., Materials and Methods: We retrospectively analyzed our data between May 2013 and April 2015 to identify the cases of bone only metastasis and visceral metastasis and tried to analyze their outcomes with paclitaxel- and carboplatin-based chemotherapy and bisphosphonates (for bone metastasis only)., Results: Totally, 12 cases with bone only metastasis (Group 1) and 43 cases with visceral metastasis (Group 2) were identified. Most common sites of bone metastasis were vertebrae (66.67%) and pelvis (25%) while that of visceral metastasis was liver (44.18%) and lung (34.88%). Only 33.33% and 34.88% of cases in Group 1 and Group 2, respectively, could complete all six cycles of chemotherapy. Overall, response rates were 41.67% and 30.32% in Group 1 and Group 2, respectively. Median progression-free survival and overall survival (OS) were 10 months and 14 months, respectively, in Group 1 as compared to 4 months and 9 months, respectively, in Group 2. The difference in survival was statistically significant., Statistical Analysis Used: It was carried out by SPSS software version 20., Conclusion: Bone only metastasis is a rare and distinct entity with favorable outcomes as compared to visceral metastasis. However, disease remains aggressive and poor OS emphasizing the need of further research., Competing Interests: There are no conflicts of interest.

- Abstract
Background: Breast cancer is the most common female cancer seen globally. Triple-negative breast cancer (TNBC) is a special subtype without any obvious target and optimum treatment remains challenging. The aim was to study the clinical, pathological profile and treatment outcome of TNBC patients., Methods: This was a retrospective observational study of TNBC patients diagnosed from January 2010 to June 2012 at a tertiary cancer center in South India. Patient's clinical and pathological characteristics were studied. The 5-year estimate of survival for non-metastatic TNBC was done using the Kaplan-Meier method., Results: Out of 804 patients of breast cancer, 237 were diagnosed as TNBC. The median age was 45 years and 58% were premenopausal. The 5-year disease-free survival (DFS) and overall survival (OS) for non-metastatic TNBC patients were 59% and 74%, respectively. The addition of a taxane to anthracycline-based regimen did not show a significant difference in DFS (P = 0.885) as well as OS (P = 0.856)., Conclusion: The role of adding taxanes to anthracycline-based chemotherapy in adjuvant setting for TNBC remains controversial and larger prospective studies are warranted., Competing Interests: The authors declare that there are no actual or potential conflicts of interest in relation to this article.

- Abstract
Context: Nasopharyngeal carcinoma (NPC) is a rare head and neck cancer with significant geographical variation. There are limited data on epidemiology and outcomes of NPC reported from Southern India., Settings and Design: Retrospective analysis., Materials and Methods: We analyzed our hospital data between January 2005 and December 2011 with NPC and analyzed their demographic parameters and outcomes with therapy., Results: A total 143 cases of NPC were identified. Median age at presentation was 35 years with male predominance. Majority (84%) of the cases had the WHO Type 3 histology. Nodal metastasis at presentation was seen in 90% of the cases, majority being bilateral. Distant metastasis was seen in 16% of the cases, most commonly at bone, lung, and liver. Concurrent chemoradiation with weekly cisplatin was offered to 84.7% of localized disease while 80% of these also received adjuvant chemotherapy. Complete remission and partial remission were achieved in 66.1% and 15.2% of the cases, respectively. Weekly cisplatin was well tolerated with Grade 3-4 toxicity seen in 22% of cases. At a median follow-up of 20 months, 2-year progression-free survival and overall survival were 67.2% and 79.5%, respectively., Statistical Analysis Used: SPSS software version 20., Conclusion: NPC is a rare head and neck malignancy in Southern India, presenting with advanced stage and more propensity to distant metastasis. It has good outcomes to concurrent chemoradiation with weekly schedule of cisplatin being well-tolerated regime. Further prospective studies to test this schedule and other novel agents in this potentially curable malignancy are warranted., Competing Interests: There are no conflicts of interest.

- Abstract
Background: Hepatocellular carcinoma (HCC) is a major health burden and the seventh most common cause of cancer-related death in India. Patients with advanced unresectable HCC have a poor prognosis with a reported median survival of only 2-3 months with the best supportive care (BSC). Sorafenib is the only drug that has demonstrated a survival benefit over BSC in advanced HCC. Unfortunately, even though it has been used for a long time, there are very few published data regarding the experience of sorafenib therapy in advanced HCC from India., Materials and Methods: Patients diagnosed with advanced HCC from January 2012 to July 2017 at our center were reviewed retrospectively. Patients' profile, time to progression, survival, and toxicity of sorafenib therapy were evaluated., Results: Of the 48 advanced patients with HCC, 35 (72.9%) were male. The median age at diagnosis was 52 years. The most common presenting symptom was abdominal pain (77%, n = 37), followed by abdominal distension (37.5%, n = 18), loss of appetite and/or weight (33.3%, n = 16), and jaundice (16.7%, n = 8). Hepatitis B virus infection was documented in 37 patients (77%), whereas 4 patients had hepatitis C virus infection. Patients were treated with standard dose sorafenib (n = 30), BSC alone (n = 14), or transarterial chemoembolization followed by sorafenib (n = 4). Sorafenib therapy was well-tolerated in most cases. The median progression-free survival with upfront sorafenib was 4.3 months. The median overall survival (OS) of the patients who received upfront sorafenib was significantly better than those treated with BSC alone (5.9 vs 3.0 months; log-rank P= 0.00)., Conclusion: Sorafenib therapy was well-tolerated and provided about 3 months longer median OS in our patients with advanced HCC than those treated with BSC alone., Competing Interests: There are no conflicts of interest

- Abstract
Introduction: Many attempts have been made to develop risk prediction scores for chronic myeloid leukemia in chronic phase (CML-CP) to identify the subgroup with a poorer response to therapy to enable early intensification of treatment. Because the bone marrow (BM) provides a more sensitive reflection of the disease process, we hypothesized that using BM parameters in the Sokal and European Treatment and Outcome Study (EUTOS) risk scores could improve their efficacy in an imatinib-treated population., Materials and Methods: We analyzed cases of CML-CP for their response and survival outcomes with imatinib using risk groupings determined by the Sokal and EUTOS scores using peripheral blood (PB) or BM parameters (Sokal-PB, Sokal-BM, EUTOS-PB, and EUTOS-BM)., Results: A total of 371 cases were analyzed. The concordance for risk groups was greater for the EUTOS scores (81.9%) than for the Sokal scores (68.1%) using PB versus BM parameters. For all 4 risk scores, the predictive efficacy was statistically significant. EUTOS-PB and EUTOS-BM could better prognosticate for progression-free survival (PFS) and overall survival (OS) between the low- and high-risk groups (P < .0001). However, with the Sokal risk score, the use of BM parameters improved the prognostic capacity for PFS between the low- and intermediate-risk groups, with a statistically significant difference (P = .025), but not for OS (P = .88)., Conclusion: The use of BM parameters, a simple method that is feasible in routine clinical practice could improve the prognostic efficacy of the Sokal score for PFS but not for OS in low- and intermediate-risk groups. Further research to improve the sensitivity of risk scores for CML-CP prognosis and attempts at risk-directed therapy is warranted., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Ganguly S, Lakshmaiah KC, Jacob LA, Babu S, Dasappa L, and Govind Babu KS
- Abstract
Sokal index was developed in the pre-imatinib era to predict and prognosticate the outcome of Chronic myeloid leukemia (CML) patients. In the Imatinib era, a new scoring system called EUTOS scoring system has been validated as a predictive marker in CML. The scores have shown variable correlation with complete cytogenetic response (CCyR) and major molecular response (MMR). To assess the performance of Sokal score and EUTOS score as a predictive marker for CCyR and MMR for newly diagnosed CML-CP patients treated with TKIs. 273 patients with newly diagnosed CML were included in the study. They were treated with upfront imatinib. They were followed up for a median period of 3 years. Cytogenetic and Molecular response to the treatment were monitored regularly. Out of 273 patients, 174 patients (63 %) were having low EUTOS score and 99 (37 %) were having high EUTOS score. Patients with low, intermediate and high sokal scores were 237 (86.8 %), 28 (10.3 %) and 8 (2.9 %) respectively. 122 patients with low EUTOS score achieved CCyR within 18 months compared to 42 patients with high EUTOS score ( p = 0.000).113 patients with low EUTOS score achieved MMR in 18 months compared to 33 patients with high EUTOS score ( p = 0.000). 148, 14, 2 patients with low, intermediate and high Sokal score respectively have achieved CCyR in 18 months ( p = 0.054). 133, 11, 2 patients with low intermediate and high sokal score respectively have achieved MMR in 18 months.( p = 0.06). EUTOS is better than Sokal score in predicting the outcome of patients of CML treated with imatinib., Competing Interests: All the authors declare that they have no conflict of interest Informed Consent Informed consent was obtained from all the individual participants Ethical Approval For this type of study formal consent is not required.

- Abstract
Introduction: Chronic myeloid leukemia (CML) is a myeloproliferative disorder characterized by Philadelphia (Ph) chromosome with classical t(9;22)(q34;q11) seen in up to 90% of cases. However 5% to 10% of patients who present with variant Ph translocations (vPh) have been an area of research for their significance in predicting response to various therapies including tyrosine kinase inhibitors as well as prognosticating survival outcomes for many years involving varied patient populations, with conflicting results., Materials and Methods: We retrospectively analyzed our data from January 2002 to December 2014. Patients with vPh in chronic phase of CML (CML-CP) were analyzed with respect to their demographic parameters, response to imatinib therapy, and survival and their data were compared with data of patients with classical Ph translocation (cPh)., Results: Of 615 patients diagnosed with CML-CP, 72 patients (11.7%) showed vPh. Most common chromosomes involved in these translocations were 14 (13.9%), 11 (12.5%), 19 (9.7%), and 7 (8.3%). Rates of complete hematological response, complete cytogenetic response, and major molecular response were not statistically different between the groups. At 5 years, event-free survival, failure-free survival, progression-free survival, and overall survival were 60% versus 67.9%, 62.7% versus 69.7%, 84.7% versus 92.1%, and 87.5% versus 92.4%, respectively, in vPh and cPh. The differences in survival were statistically not significant., Conclusion: To our knowledge, this is the largest series of variant translocations in CML-CP, pertaining to the Indian population. Our data suggest that the presence of vPh in CML has no significant effect in predicting response to imatinib as well as in prognosticating survival., (Copyright © 2016 Elsevier Inc.

- Abstract
Chronic myeloid leukaemia (CML) is a myeloproliferative disorder. Over the years many prognostic models have been developed to better risk stratify this disease at baseline. Sokal, Euro, and EUTOS scores were developed in varied populations initially receiving various therapies. Here we try to identify their predictive and prognostic implication in a larger population of Indian patients with CML-CP (chronic phase) in the imatinib era.

- Abstract
Purpose. Neuroendocrine neoplasms (NENs) of the esophagus are very uncommon with only a few studies published worldwide. Studies on clinical profile, management, and outcomes are very uncommon. Methods. We report the largest single institution retrospective review of 43 patients of pure esophageal NENs out of our registry of gastrointestinal neuroendocrine tumors treated between 2005 and 2014. Data on the incidence, tumor location, clinical symptoms, stage at presentation, grading, treatment protocol, and treatment outcomes was collected and analyzed. Results. Among 1293 cases of esophageal cancers, pure esophageal NENs were diagnosed in 43 cases. The mean patient age was 55.8 years. The male : female ratio was 1.5 : 1. 81.4% of the tumors were located in the lower third of the esophagus and gastroesophageal junction. Neuroendocrine carcinomas (NEC; G3) accounted for the vast majority of NENs (83.7%). 53.5% patients were Stage IV and 32.5% were Stage III at presentation. The combined median survival of stages II and III patients was 18.25 months, with treatment. The median survival of treated patients with metastatic disease was 6.5 months. Conclusion. Esophageal NENs most commonly were neuroendocrine carcinomas, presented in metastatic stage and were associated with poor prognosis. Grade 2 (G2) tumors had better outcomes than NEC (G3). In nonmetastatic disease, presence of lymph node metastasis and unresectable disease had poorer outcomes.

- Abstract
Background. The efficacy, safety, and cost benefit of olanzapine (OLN) when compared to aprepitant (APR) in the prevention of chemotherapy induced nausea and vomiting (CINV) in patients receiving highly emetogenic chemotherapy (HEC) were evaluated. Methods. A prospective pilot study was done in chemotherapy-naive patients receiving HEC to compare OLN versus APR along with palonosetron and dexamethasone. 100 patients consented to the protocol and were randomized and evaluated for Complete Response (CR) (no emesis, no rescue). Results. CR was 86% for the acute period, 86% for the delayed period, and 80% for the overall period in 50 patients receiving the APD regimen. CR was 84% for the acute period, 88% for the delayed period, and 78% for the overall period for 50 patients receiving the OPD regimen. Patients without nausea were APD: 88% acute, 84% delayed, and 84% overall, and OPD: 84% acute, 88% delayed, and 84% overall. There were no significant grade 3 or 4 toxicities. OPD was comparable to APD in the control of CINV. Conclusion. In this study, there was no significant difference between olanzapine and aprepitant in preventing CINV with highly emetogenic chemotherapy. Olanzapine may thus be used as a potential, safe, and cost beneficial alternative to prevent nausea and vomiting in HEC.

- Abstract
Background: Oral cavity cancer is a significant health problem in India. Majority of patients present with locally advanced disease requiring multimodality treatment. Compliance to recommended treatment is an important factor affecting outcome., Aims: The aim was to evaluate the outcome of locally advanced oral cavity cancer patients with regards to treatment adherence and to assess reasons of noncompliance., Materials and Methods: This was a prospective observational study. We included patients referred to Department of Medical Oncology for induction chemotherapy in view of locally advanced oral cavity cancer., Results: Only 15 (26%) patients completed planned treatment schedule. Their 1 year overall survival was 93%. The remaining 43 patients who received inadequate treatment had a dismal 21% 1 year overall survival. Illiteracy, poverty, long waiting list for surgery, prolonged delay for health scheme treatment plan approval and dissatisfaction with attitude of hospital staffs are major barriers related to effective treatment of these patients., Conclusions: A detailed discussion with patient and their relatives regarding recommended treatment, proper implementation of health schemes, increasing trained manpower to avoid long waiting list for surgery, provision of additional financial support for family member accompanying the patient and a sympathetic approach toward patients are needed to help these patients overcome the battle.

- Abstract
Background: Intrathecal methotrexate (ITMTX) is an important component in the treatment as well as prophylaxis of leukemia/lymphoma. ITMTX can cause chemical meningitis characterized by vomiting, headache, and fever lasting 2-5 days with spontaneous resolution of symptoms which differentiates this syndrome from bacterial meningitis., Objective: This prospective observational study was carried out to determine incidence of post-ITMTX syndrome in patients receiving prophylactic ITMTX as part of Berlin-Frankfurt-Munster (BFM) protocol., Materials and Methods: Patients aged 15-50 years receiving BFM 90 or BFM 95 protocol for acute lymphoblastic leukemia or lymphoblastic lymphoma were followed up for post-ITMTX syndrome, defined as vomiting, headache and fever between 38° and 39°C following ITMTX., Results: Thirty-three patients received a total of 297 courses of ITMTX. Of the 297 doses of ITMTX, 20 episodes (6.7%) of post-ITMTX syndrome were observed. The incidence of post-ITMTX syndrome was highest after the second dose of ITMTX (24%). The most common symptom of post-ITMTX syndrome was headache which was seen in 17 (85%) patients. Seventeen (85%) patients had vomiting, 10 (50%) patients had fever, and 4 (20%) patients had backache. Meningeal signs were present in 2 (10%) patients., Conclusions: Post-ITMTX syndrome is not uncommon in adult patients receiving prophylactic ITMTX for treatment of acute lymphoblastic leukemia and lymphoblastic lymphoma. Patients develop a toxic syndrome closely mimicking acute bacterial meningitis but spontaneous recovery is seen without any neurological sequelae.

- Abstract
Introduction: Primary gastrointestinal tract mantle cell lymphoma is very rare. There is paucity of literature regarding natural history and outcome of this unusual entity., Aims and Objectives: The aim of the present study was to analyze clinical profile, epidemiological parameters, and outcome of primary gastrointestinal mantle cell lymphoma patients treated at our institute., Materials and Methods: This was a retrospective observational study of consecutive patients diagnosed with primary gastrointestinal mantle cell lymphoma at our institute between 2001 and 2012., Results: A total of seven patients, all males with a median age of 67.7 years, were diagnosed with primary gastrointestinal mantle cell lymphoma. Sites involved were the stomach, colon, and rectum. Blastoid and diffuse variants were observed in three patients each, and one patient had nodular pattern. Five patients received cyclophosphamide, adriamycin, vincristine, and prednisolone (CHOP) chemotherapy. Only one patient achieved complete remission and remained disease free for 21 months before being lost to follow up. The remaining four patients had inadequate response to CHOP chemotherapy with a median survival of 6 months. Cyclophosphamide, vincristine, prednisolone (CVP) was given to one patient in view of poor performance status. He had progressive disease and died after first cycle of chemotherapy. One patient is currently undergoing treatment and receiving rituximab with chemotherapy., Conclusions: Primary gastrointestinal mantle cell lymphoma is highly aggressive with the Mantle Cell Lymphoma International Prognostic Index (MIPI) scores in high-risk group; survival is poor compared to nodal mantle cell lymphoma involving the gastrointestinal tract; patients respond poorly to CHOP chemotherapy. As majority of patients are elderly and not eligible for transplant, the use of rituximab in remission induction and maintenance should be considered to improve outcome of these patients.

- Abstract
Objective: Bavituximab is a phosphatidylserine (PS)-targeting monoclonal antibody with immune-modulating and tumor-specific vascular targeting properties. Preclinical studies have shown activity against numerous solid tumors and at least an additive effect in combination with chemotherapy. This study evaluated bavituximab in combination with paclitaxel and carboplatin in patients with previously untreated, locally advanced or metastatic non-small-cell lung cancer (NSCLC)., Patients and Methods: This phase II, open-label study (NCT00687817) was conducted in 49 patients with stage IIIB/IV NSCLC utilizing a Simon two-stage design. Patients were treated with up to six cycles of carboplatin area under the concentration-time curve (AUC) 5 plus paclitaxel 175 mg/m2 every 21 days with weekly bavituximab 3 mg/kg followed by bavituximab monotherapy until progression or unacceptable toxicity., Results: The primary efficacy endpoint of overall response rate (ORR) was 40.8% (complete response [CR] 2.0%, partial response [PR] was 38.8%). Median progression-free survival (PFS) and overall survival (OS) were 6.0 and 12.4 months, respectively. Treatment-related adverse events (AEs) occurred in 40.8% of patients. The most common treatment-related AEs were anemia (10.2%), asthenia, vomiting, paresthesia, anorexia, and fatigue (6.1% each). One patient with a central, cavitating squamous tumor developed fatal hemoptysis and aspiration., Conclusion: Bavituximab in combination with paclitaxel-carboplatin as first-line therapy demonstrated a tolerable safety profile and potential efficacy in this single-arm phase II trial in patients with advanced local or metastatic NSCLC. Randomized trials with this regimen are in progress., Clinicaltrialsgov Identifier: NCT00687817., (Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
Background: Primary testicular lymphoma constitutes 1-2% of Non-Hodgkin's lymphomas affecting elderly men >60 years of age. Most often it is a Diffuse large B cell lymphoma (DLBCL) and treatment involves multimodality approach involving surgery, chemotherapy and radiotherapy. Outcome remains poor in spite of aggressive therapy., Materials and Methods: We retrospectively reviewed 286 registered cases of DLBCL (aged >14 years) from 2007 to 2011 and found nine primary testicular involvement patients. These cases were analyzed for baseline clinical features, investigations, staging, treatment and outcome., Results: Median age was 58 (46-76) years. All patients presented with testicular swelling, two had the presence of B symptoms, and three with abdominal lymphadenopathy. Six had stage IE disease and three patients had stage IIE. All patients underwent orchiectomy. Eight patients received combination chemotherapy and six completed three or more cycles. Four achieved complete response, among these three relapsed after 32, 42, 70 months and one was lost to follow up. Two had a progressive disease, among these one died of disease and one alive with disease. Complete follow up was available from five patients and median survival was 36 months (11-78 months)., Conclusion: Primary testicular DLBCL is uncommon, needs multimodality treatment and central nervous system prophylaxis to improve the survival. The outcome needs to be further investigated using biological approaches (Rituximab based) and/or more aggressive management.

- Abstract
Background: Human immunodeficiency virus (HIV) associated lymphoma is an important public health concern; however, the epidemiological data available from India is sparse., Aims: The present study was carried out at a tertiary cancer care center in South India to analyze the scenario of HIV-associated lymphoma., Materials and Methods: This was a retrospective observational study conducted at our center, on consecutive patients diagnosed with HIV-associated lymphoma, from January 2008 to December 2012., Results: A total of 44 patients were diagnosed with HIV-associated lymphoma, of which 18 opted for treatment. There were 11 males and 7 females in the study population. Median interval from the diagnosis of HIV infection to diagnosis of lymphoma was 18 months. Median CD4 count at the time of lymphoma diagnosis was 218/mm(3). Five patients had Hodgkin's lymphoma, and the rest had non-Hodgkin's lymphoma. Five out of 18 (28%) patients in the present study expired during treatment. Ten (55.5%) patients are alive and lymphoma free, with a median follow up of 18 months., Conclusions: More than half of our treated patients are lymphoma free with a median follow up of 18 months; hence treatment of patients with HIV-associated lymphoma should be encouraged.

- Abstract
Background: This randomized phase II trial was designed to compare the rate of pathologic complete response (pCR) induced by neoadjuvant cyclophosphamide plus doxorubicin (AC) followed by ixabepilone or paclitaxel in women with early stage breast cancer (BC). Expression of βIII-tubulin as a predictive marker was also evaluated., Patients and Methods: Women with untreated, histologically confirmed primary invasive breast adenocarcinoma received four cycles of AC followed by 1:1 randomization to either ixabepilone 40 mg/m2 (3-hour infusion) every 3 weeks for four cycles (n = 148) or weekly paclitaxel 80 mg/m2 (1-hour infusion) for 12 weeks (n = 147). All patients underwent a core needle biopsy of the primary cancer for molecular marker analysis prior to chemotherapy. βIII-Tubulin expression was assessed using immunohistochemistry., Results: There was no significant difference in the rate of pCR in the ixabepilone treatment arm (24.3%; 90% confidence interval [CI], 18.6-30.8) and the paclitaxel treatment arm (25.2%; 90% CI, 19.4-31.7). βIII-Tubulin-positive patients obtained higher pCR rates compared with βIII-tubulin-negative patients in both treatment arms; however, βIII-tubulin expression was not significantly associated with a differential response to ixabepilone or paclitaxel. The safety profiles of both regimens were generally similar, although neutropenia occurred more frequently in the ixabepilone arm (grade 3/4: 41.3% vs. 8.4%). The most common nonhematologic toxicity was peripheral neuropathy., Conclusions: Neoadjuvant treatment of early stage BC with AC followed by ixabepilone every 3 weeks or weekly paclitaxel was well tolerated with no significant difference in efficacy. Higher response rates were observed among βIII-tubulin-positive patients.

- Abstract
Radiotherapy has a significant impact on the local tumor environment and its distant component. Abscopal effect is the bystander effect of radiotherapy observed at a site distant to that irradiated within the same subject. Abscopal effect even though described, is not a common clinical event. We report a documented observation of abscopal effect in a patient of Chronic Lymphocytic Leukemia during radiation therapy.
