Imaging resemblance but diagnostic disparity in cervix cancer: a rare case report

F-18 FDG PET-CT is an establish modality for staging of cervical cancer. The high uptake value in PET with no evidence of necrosis in CECT is generally understood malignant pathology in known cancer patients. A 47 year-old-female with cervix carcinoma underwent staging FDG PET-CT. It showed FDG avid primary lesion in cervix with FDG avid pelvic, retroperitoneal, mediastinal and supraclavicular lymph nodes. USG guided FNA from the supraclavicular lymph node revealed tuberculosis. Now patient scheduled for ATT and chemotherapy.

Unusual metastatic sex cord stromal tumor - staging and response assessment

Metastatic sex cord stromal tumor (SCST) is rare and contributing <1% of ovarian tumors. A 42-year-old female presented with lower abdominal pain for 2 months. Ultrasonography revealed masses in the abdominal and pelvic. USG guided biopsy from the pelvic mass revealed SCST. For staging, whole body F-18 fluorodeoxyglucose positron emission tomography-computed tomography was performed and revealed heterogenous mildly FDG avid retroperitoneal and bilateral pelvic masses with lung nodules. To confirm the nature of the lung nodule; PET-CT guided biopsy performed and revealed metastatic SCST. After three cycle of chemotherapy, clinical, biochemical and imaging show partial response to treatment.

Molecular response to imatinib & its correlation with mRNA expression levels of imatinib influx & efflux transporters in patients with chronic myeloid leukaemia in chronic phase.

Background & objectives: Imatinib is the standard first-line treatment for chronic myeloid leukaemia (CML) patients. About 20 to 30 per cent patients develop resistance to imatinib and fail imatinib treatment. One of the mechanisms proposed is varying expression levels of the drug transporters. This study was aimed to determine the expression levels of imatinib transporter genes (OCT1, ABCB1, ABCG2) in CML patients and to correlate these levels with molecular response. Methods: Sixty three CML chronic phase patients who were on 400 mg/day imatinib for more than two years were considered for gene expression analysis study for OCT1, ABCB1 and ABCG2 genes. These were divided into responders and non-responders. The relative transcript expression levels of the three genes were compared between these two categories. The association between the expression values of these three genes was also determined. Results: No significant difference in the expression levels of OCT1, ABCB1 and ABCG2 was found between the two categories. The median transcript expression levels of OCT1, ABCB1 and ABCG2 genes in responders were 26.54, 10.78 and 0.64 versus 33.48, 7.09 and 0.53 in non-responders, respectively. A positive association was observed between the expression of the ABCB1 and ABCG2 transporter genes (r=0.407, P<0.05) while no association was observed between the expression of either of the ABC transporter genes with the OCT1 gene. Interpretation & conclusions: Our findings demonstrated that the mRNA expression levels of imatinib transporter genes were not correlated with molecular response in CML patients. further studies need to be done on a large sample of CML patients to confirm these findings.

Transradial primary angioplasty and stenting in Indian patients with acute myocardial infarction: acute results and 6-month follow-up.

BACKGROUND: Coronary angioplasty and stent implantation is effective as primary intervention in acute myocardial infarction. Because of fewer puncture site complications and improved patient comfort, transradial access has been increasingly used as an alternative to transfemoral access for percutaneous coronary interventions. METHODS AND RESULTS: We studied 103 patients (94 men, 9 women: mean age 52.5 +/- 11.96 years) with a diagnosis of acute myocardial infarction (<12 hours after onset), who underwent primary percutaneous coronary intervention. Transradial access was used in all patients with a normal Allen's test and transfemoral access was used additionally only if intra-aortic balloon counterpulsation was required. Follow-up duration was 6 months. Transradial access was successfully achieved in all patients. Radial artery cannulation took <2 min in more than 85% patients. During percutaneous coronary intervention, cannulation to balloon inflation times and total procedure times were 11.3 +/- 5.2 min and 19.9 +/- 10.8 min, respectively. Stents were implanted in 99 (96.1%) patients andplain balloon angioplastywas performed in 3.9%. The primary success rate was 98.1%, with no major bleeding complications. Total length of hospitalization averaged 2.4 +/- 0.8 days. In-hospital major adverse clinical events rate was 5.9%. Six-month clinical follow-up was achieved for 84 (86.6%) patients. Six (7.1%) patients died during follow-up. Follow-up coronary angiography was performed in 22 (26.2%) patients. After 6 months, 7 patients required revascularizationof the target lesion. The rate of survival without myocardial infarction, bypass surgery or repeat coronary angioplasty was 88.5% at 6 months. CONCLUSIONS: Transradial access may represent a safe and feasible technique for performing primary percutaneous coronary intervention with good acute results and without major bleeding complications.

Safety and efficacy of an indigenous recombinant interferon-alpha-2b in patients with chronic myelogenous leukaemia: results of a multicentre trial from India.

BACKGROUND: Compared to hydroxyurea, treatment with interferon-alpha (IFN-alpha) is known to prolong survival in patients with chronic phase of chronic myelogenous leukaemia (CML) and was considered as first-line therapy till recently. We conducted a multicentre trial using an indigenous recombinant IFN-alpha-2b to evaluate its efficacy and toxicity in chronic phase CML. METHODS: Between September 2000 and August 2001, patients with chronic phase CML were recruited within 8 weeks of diagnosis at 7 centres in India. The study was approved by the Ethics Committee of each participating Institute and Informed, written consent was obtained from all patients. All patients were given the study drug in a dose of 5 million units daily subcutaneously. Response and survival analyses were done with intent-to-treat analysis. RESULTS: One hundred and fourteen patients (75 men and 39 women) were included in the study. Their ages ranged from 18 to 62 years (median 37 years). Fifty-seven per cent of patients had a haematological response; complete response in 31.6% and partial response in 25.4%. The median time to achieve complete haematological response was 6 months (range 3-12 months). Cytogenetic response was seen in 39.4% of patients; complete in 1.8%, partial in 28% and minimal in 9.6%. The median time to achieve partial and complete cytogenetic response was 6 and 12 months, respectively. Nineteen patients had progression (blast crisis n=15, accelerated phase n=4) while on treatment. Two patients refused further treatment after the initial 4 weeks due to IFN-a toxicity, mainly bone pains and fever. The major toxic effects of treatment were fever (78%), fatigue (25.4%) and myalgia (52%). No patient died of toxicity. Currently, 95 patients are alive, 91 in the chronic phase and 4 in the accelerated phase. Four patients were lost to follow up and all 15 patients with blast crisis died of progressive disease at a median Interval of 6.5 months (range 1-15 months). The Kaplan-Meier probability of survival at 36 months was 76%. CONCLUSION: This study confirms the efficacy of the indigenous recombinant IFN-alpha-2b in chronic phase CML. The drug has a toxicity profile similar to that of other preparations.
