Acute myocardial infarction--an unusual presentation of non-specific aortoarteritis.

A 42 year old man presented with classical presentation of Acute ST elevation MI of 2 hours duration. His CAG revealed a spared LMCA with a totally occluded LAD in proximal segment, for which he underwent a successful PAMI with DES to LAD. 2 days later he developed high grade fever, elevated inflammatory markers (ESR/CRP) with a dull aching pain in root of neck. On evaluation of brachiocephalic vessels, CT Aortogram suggested a diagnosis of acute onset Non-Specific Aortoarteritis. Nonspecific Aortoarteritis in young males is an uncommon presentation, though associated coronary artery involvement is known, but its presentation as an Acute MI is a rare phenomenon.

Rotastenting in an anomalously arising right coronary artery after an ugly dissection.

Rotational atherectomy is contraindicated in dissected coronary arteries since it can lead to progression of the dissection or perforation. In our case, the right coronary artery (RCA) arose anomalously from the left coronary sinus. The lesion in the RCA was an undilatable calcified one. There was a dissection in the RCA due to high pressure balloon dilatation. Since the patient was hemodynamically unstable and there were no options besides rotablation, we proceeded with caution. Rotablation and stenting were successfully done. Our case report highlights the importance of the need for good guide catheter support even in the presence of anomalously arising arteries and the rotablation option for unyielding calcified coronary lesions, even in the setting of a dissection.

Left atrial spindle cell sarcoma - case report.

Primary spindle cell sarcoma of the left atrium is an extremely rare tumour. Surgical excision is the mainstay of treatment since it responds poorly to chemotherapy or radiotherapy. In spite of all the treatment, the prognosis remains poor due to inadvertent delay in diagnosis, few therapeutic options and propensity to metastasize. We present a 47-year-old male who underwent a surgical excision of a left atrial mass in February 2010. It was proved to be a high-grade spindle cell sarcoma on histopathology. He presented again in October 2010 with recurrence of the tumour for which he was re-operated. However, the tumour recurred again within one month, to which the patient succumbed.

Reduced risk of breast cancer recurrence in patients using ACE inhibitors, ARBs, and/or statins.

BACKGROUND: Epidemiologic and biochemical evidence suggest a role of statins and angiotensin-converting enzyme (ACE) inhibitors or angiotensin-receptor blockers (ARBs) as anti-neoplastic agents. This study was designed to evaluate the association between the use of these agents and the risk of breast cancer recurrence. METHODS: We reviewed the medical records of patients treated for stage II/III breast cancer between 1999 and 2005. Statin and ACE-inhibitors/ARB users were defined as patients who took these medications for at least 6 months in no evidence of disease (NED) stage after the initial diagnosis. The primary outcome was disease-free survival and the secondary was overall survival. The Kaplan-Meier and Cox proportional hazard models were used. RESULTS: A total of 703 patients were included. The median and maximal of follow up was 55 and 118 months, respectively. A total of 168 patients used ACE-inhibitors/ARBs, 156 patients used statins, and 81 used both. Univariate analysis showed significant reduction in breast cancer recurrence among patients who used ACE-inhibitors/ARBs (hazard ratio (HR) = 0.57; 95% CI: 0.37-0.89; p = .013) or statins (HR = 0.43; 95% CI: 0.26-0.70; p < .001). After adjusting for multiple variables, the use of ACE-inhibitors/ARBs (HR = 0.49; 95% CI: 0.31-0.76; p = .002) and statins (HR = 0.40; 95% CI: 0.24-0.67; p < .001) remained significant and an additive effect was found on those who used both drugs (HR = 0.30 95% CI: 0.15-0.61; p = .001). No association was found regarding overall survival. CONCLUSIONS: The use of ACE-inhibitors/ARBs, statins, and the combination of both were all associated with a reduced risk of breast cancer recurrence. This observation should prompt further exploration.

Predictors of success in percutaneous Coronary intervention for chronic total occlusion.

We performed a retrospective analysis of 146 chronic total occlusion CTO patients to evaluate the antecedents of success and failure in CTO - Percutaneous Coronary Intervention (PCI) in Indian patients. The study aimed to identify the technical success rate, analyse immediate patient outcomes, and understand the factors impacting the successful outcomes. Our results showed that J-CTO (Multicenter CTO Registry of Japan) scores correlate well with the success rates of CTO-PCI and two most important factors deciding failure are lesion length more than 20 mm and lesions with calcification. Most important step to success of CTO is wiring, once wire crosses the segment, success rates of the procedure is around 97%. The wire escalation strategy has to be modified once the initial soft (polymer) wire fails, it's reasonable to use high tip load wire like conquest pro without the use of intermediate wires (except in presence of tortuosity). At 1 year follow up of these patients, there was a statistically significant drop in angina class and major adverse cardiac event rates in the successful CTO group.

Phase II trial of doxorubicin/docetaxel/cyclophosphamide for locally advanced and metastatic breast cancer: results from NSABP trial BP-58.

Based on the recommended phase II doses for doxorubicin (60 mg/m2) and docetaxel (60 mg/m2) and the National Surgical Adjuvant Breast and Bowel Project's (NSABP) experience with doxorubicin and cyclophosphamide (cyclophosphamide 600 mg/m2), we conducted a phase II trial at 18 institutions using doxorubicin/docetaxel/cyclophosphamide (ATC) given every 21 days, in preparation for a major adjuvant breast cancer study (NSABP B-30), in which ATC would be used. Eligibility requirements included measurable stage IIIB/IV breast cancer, performance status 0-2, normal left ventricular ejection fraction, and no prior chemotherapy for metastatic disease (nontaxane adjuvant chemotherapy was allowed if completed > 12 months before entry and if the cumulative dose of doxorubicin was =240 mg/m2). Eighty-nine patients were entered who ranged in age from 30-78 years (38.2% < 50 years; 61.8% =50 years). A total of 33.7% of patients had stage IIIB disease, and 66.3% had stage IV disease. Among the stage IV patients, 20.3% had received prior adjuvant chemotherapy. Dexamethasone premedication (8 mg p.o. b.i.d. for 3 days) and prophylactic ciprofloxacin (500 mg p.o. b.i.d. days 5-15) were used. Colony-stimulating growth factors were reserved for secondary prophylaxis after prolonged or febrile neutropenia (FN) or documented severe infection in a prior cycle. After a cumulative dose of doxorubicin 480 mg/m2, patients could continue with docetaxel/cyclophosphamide alone. Eighty-nine patients and 577 courses were evaluable for toxicity. Median time on study as of May 2002 was 36.5 months (range, 28-47 months). Febrile neutropenia occurred in 34 patients (38%); 8 developed FN in the absence of prior prophylactic growth factor support; 26 developed FN despite prior growth factor support (for one patient this information was unavailable). There were no septic deaths. One patient died from pulmonary embolism. Other grade 3/4 adverse events included: nausea (9%), vomiting (7%), stomatitis (6%), diarrhea (4%), arthralgia/myalgia (3%), and neurotoxicity (1%). Clinical congestive heart failure was seen in 3 patients (3.4%). Seventy-seven patients were evaluable for best response within 6 cycles of therapy. Thirteen patients (16.9%) had a complete response, 43 (55.8%) had a partial response, for an overall response rate of 72.7%. The median response duration was 23.8 months (95% CI, 16.2-37.8 months), and the median time to progression or death was 23.5 months (95% CI, 16.3-38.7 months). The median survival time was 35.6 months (95% CI, 26.6-39.4 months). The administration of ATC with primary ciprofloxacin and secondary colony-stimulating factor prophylaxis is feasible and active. Its value in the adjuvant setting is currently under investigation.

A phase II neoadjuvant trial of sequential nanoparticle albumin-bound paclitaxel followed by 5-fluorouracil/epirubicin/cyclophosphamide in locally advanced breast cancer.

BACKGROUND: Neoadjuvant chemotherapy has become standard treatment for women with locally advanced breast cancer (LABC). Various regimens have explored the addition of newer agents to determine safety and efficacy. The aim of this phase II study was to incorporate albumin-bound paclitaxel with sequential anthracycline-based therapy. PATIENTS AND METHODS: Sixty-six women with LABC but without prior treatment and regardless of hormone receptor or HER2 status were enrolled. All patients were to receive albumin-bound paclitaxel weekly for 12 weeks followed by 5-fluorouracil/ epirubicin/cyclophosphamide (FEC) every 3 weeks for 4 cycles. Trastuzumab was allowed in HER2-positive (HER2+) patients. Primary endpoint was pathologic complete response (pCR; CR) in breast. Secondary endpoints included pCR in breast and nodes, clinical CR, 2-year progression-free survival, and overall survival. RESULTS: Sixty-five patients received at least 1 dose of chemotherapy and were included in this analysis. Sixty-three patients completed 4 cycles of albumin-bound paclitaxel. Sixty-two patients received at least 1 dose of FEC, and 58 completed 4 cycles. Seventeen of 19 HER2+ women received trastuzumab. The pCR in breast was 29% (19 of 65). For the HER2+ subset, the pCR was 58% (11 of 19). Both albumin-bound paclitaxel and FEC were well tolerated. The most significant toxicities were grade 2/3 neuropathy (16%) with albumin-bound paclitaxel and grade 3/4 febrile neutropenia (7%) with FEC. CONCLUSION: Albumin-bound paclitaxel given over 12 weeks is well tolerated. Albumin-bound paclitaxel should be further evaluated in a randomized setting in both adjuvant and neoadjuvant trials.
