Clinicopathological Profile of Pure Neuroendocrine Neoplasms of the Esophagus: A South Indian Center Experience

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

Phytochemicals, Antioxidant Profile and GC-MS Analysis of Ethanol Extract of Simarouba Glauca Seeds

Medicinal plants acted as traditional medicine from the ancient time and recognized as scientific medicine in modern days. Simarouba glauca is an Indian traditional medicinal plant commonly called as “Paradise Tree or Lakshmi Taru” used for its various medicinal properties. The current study was carried out to know the phytochemicals, antioxidant profile and Gas Chromatography- Mass Spectroscopy (GC-MS) of ethanol extract of the seed S. glauca. Qualitative analysis showed the presence of flavonoids and carbohydrates, lacked alkaloids, glycosides, steroids, triterpenoids and tannins. The total flavonoid, proanthocyanidin and phenol content were 25.20 ± 0.15mg quercetin equivalent/g extract, 57.08±1.51mg catechin equivalent/g extract and 41.75 ± 2.31mg gallic acid equivalent/g extract respectively. Antioxidants exhibited maximum 2, 2-Diphenyl- 1-picrylhydrazyl (DPPH) scavenging of 70% at 100 ?g/mL concentrations with an IC50 value 50.93?g/mL, decolourization potential of 2,2’-azino-bis - (3-ethyl benzthiazoline-6-sulfonic acid (ABTS) was 65% at 203.87?g/mL concentration and ferric reducing antioxidant potential (FRAP) assay exhibited Ascorbic Acid Equivalents (AAE/ml).The relative contents of the fatty acids were calculated with area normalization by GC-MS. Out of the ten fatty acids, four of them were Ethyl oleate (24.20%), Oleic acid (16.13%), 5-Hydroxymethylfurfural (12.69%) and Hexadecanoic acid ethyl ester (12.22%) and other six fatty acids were present less than 11

Epidemiology and outcomes of nasopharyngeal carcinoma: Experience from a regional cancer center in Southern India

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

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

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
