Pancreatic acinar cell carcinoma: A comprehensive review

Acinar cell carcinoma (ACC) is a rare pancreatic malignancy with distinctive clinical, molecular, and morphological features. The long-term survival of ACC patients is substantially superior to that of pancreatic adenocarcinoma patients. As there are no significant patient series about ACCs, our understanding of this illness is mainly based on case reports and limited patient series. Surgical resection is the treatment of choice for patients with the disease restricted to one organ; however, with recent breakthroughs in precision medicine, medicines targeting the one-of-a-kind molecular profile of ACC are on the horizon. There are no standard treatment protocols available for people in which a total surgical resection to cure the condition is not possible. As a result of shared genetic alterations, ACCs are chemosensitive to agents with activity against pancreatic adenocarcinomas and colorectal carcinomas. The role of neoadjuvant or adjuvant chemoradiotherapy has not been established. This article aims to do a comprehensive literature study and present the most recent information on acinar cell cancer.     

Prevalence of abnormal upper limb arterial anatomy and its correlation with access failure during transradial coronary angiography

ObjectiveThe study aimed at to find out prevalence of abnormal upper limb arterial anatomy and its correlation with access failure during transradial coronary angiography.MethodThis was a prospective observational study of 1512 patients who had undergone transradial coronary angiography (CAG). Angiographic assessment of upper limb arterial tree was performed when the angiographic guidewire or the diagnostic catheter followed an abnormal path or got stuck in its course.ResultsAbout 5.29% patients (80/1512) were noted to have abnormal upper limb arterial anatomy. The most common abnormality detected were radio-ulnar loop in 22 (1.46%) patients, tortuous upper limb arteries 19 (1.25%) and abnormal high origin of radial artery 10 (0.66%) patients. Access failure was encountered in 4.4% (67/1512) of total patients and 64.17% (43/67) access failure was due to abnormal upper limb arterial anatomy.ConclusionAbnormal upper limb arterial anatomy was the most common cause of access failure in transradial coronary angiography in this study.     

Adenoid cystic carcinoma of female breast: A case report

INTRODUCTIONAdenoid cystic carcinoma (ACC) of the breast is a rare neoplasm accounting for 0.1% of breast carcinomas.PRESENTATION OF CASEA 30 year old female patient presented with multiple lumps in the right breast. Excision biopsy of a lump in the lower outer quadrant revealed adenoid cystic carcinoma. A right sided modified radical mastectomy (MRM) was performed, with axillary clearance. Histopathology revealed a fibroadenoma accounting for one mass and adenoid cystic carcinoma in another, confirmed on Periodic acid Schiff (PAS) staining. Three out of the eight excised axillary lymph nodes contained malignancy. There was no evidence of recurrence or distant spread at follow-up 6 months postoperatively.DISCUSSIONACC of the breast is a rare neoplasm accounting for 0.1% of breast carcinomas and is of special interest because of its favourable prognosis and distinctive histological appearance. This tumor occurs predominantly in women in their sixth decade and usually presents as a tender breast mass, often in the subareolar area though in our case it was not tender and presented as multiple lumps in the right breast. The diagnosis can be made on fine needle aspiration cytology (FNAC), but in our case FNAC was inconclusive. We performed MRM with axillary clearance, and three out eight lymph nodes proved positive for malignancy.CONCLUSIONACC is a rare malignant neoplasm. Surgical treatment is the mainstay with little role for radiotherapy and chemotherapy according to the published literature.     

Primary angiosarcoma of breast: A case report

INTRODUCTIONPrimary breast angiosarcoma is a rare form of breast cancer, accounting for only 0.04% of all malignant breast tumours.PRESENTATION OF CASEA 28-year-old woman presented with a progressive lump in the right breast for one month. Fine needle aspiration cytology (FNAC) was highly suspicious of angiosarcoma, and this diagnosis was confirmed on core needle biopsy. Modified radical mastectomy was performed as sole treatment.DISCUSSIONPrimary breast angiosarcoma is a rare type of breast malignancy, usually occurring in the third to fourth decade and only reported in women. The histological features of angiosarcoma of the breast are conventionally graded I, II or III. Total mastectomy appears to be the only treatment conferring benefit, chemotherapy and radiation therapy being of little proven value to date. The 5-year disease-free survival for grade I tumours can be as high as 76%, and up to 70% for grade II tumours whereas for grade III tumours it is reportedly about 15%.CONCLUSIONPrimary angiosarcoma of the breast is a rare malignancy with a poor prognosis, even after complete resection. Surgery is the mainstay of treatment with a limited role for chemotherapy and radiotherapy.

(E)-2-(2-Allylidenehydrazinyl)thiazole derivatives: Design,green synthesis,in silico and in vitro antimycobacterial and radical scavenging studies

By understanding the rampant infections of Mycobacterium tuberculosis (Mtb) and inflammations caused due to the generation of radical species during the Mtb infection, a series of (E)-2-(2-allylidenehydrazinyl)thiazole derivatives, with dual-action properties, was designed. The molecules were designed with a considerable variation in LogP, one of the critical parameters in physicochemical properties, and analyzed for their drug-likeness. For the synthesis, a simple, green, and multicomponent one-pot synthesis method was developed. The in vitro inhibition potentials were evaluated against Mtb H₃₇Rv by the microplate Alamar Blue assay. The results reveal that compound 6 was potent, with a MIC value of 6.5 µg/ml, and showed better interactions with the KasA protein with binding free energy (ΔG) of −9.4 kcal/mol. Also, the radical scavenging properties were studied to establish the dual-action properties of the molecules. Compound 9 exhibited promising antioxidant and nitric oxide radical scavenging activities, with 81.7% and 81.0%, respectively, at 1,000-μg/ml concentration.     

Clinicopathological correlation of radiologic measurement of post-therapy tumor size and tumor volume for pancreatic ductal adenocarcinoma

ObjectivesTumor size measurement is critical for accurate tumor staging in patients with pancreatic ductal adenocarcinoma (PDAC). However, accurate tumor size measurement is challenging in patients who received neoadjuvant therapy before resection, due to treatment-induced fibrosis and tumor invasion beyond the grossly identified tumor area. In this study, we evaluated the correlation between the tumor size and tumor volume measured on post-therapy computed tomography (CT) scans and the pathological measurement. Also, we investigated the correlation between these measurements and clinicopathological parameters and survival.Materials and methodsRetrospectively, we evaluated 343 patients with PDAC who received neoadjuvant therapy, followed by pancreaticoduodenectomy and had pre-operative pancreatic protocol CT imaging. We measured the longest tumor diameter (RadL) and the radiological tumor volume (RadV) on the post-therapy CT scan, then we categorized RadL into four radiologic tumor stages (RTS) based on the current AJCC staging (8th edition) protocol and RadV based on the median. Pearson correlation or Spearman’s coefficient (δ), T-test and ANOVA was used to test the correlation between the radiological and pathological measurement. Chi-square analysis was used to test the correlation with the tumor pathological response, lymph-node metastasis and margin status and Kaplan-Meier and Cox-proportional hazard for survival analysis. P-value < 0.05 was considered significant.ResultsAs a continuous variable, RadL showed a positive linear correlation with the post-therapy pathologic tumor size in the overall patient population (Pearson correlation coefficient: 0.72, P < 0.001) and RadV (δ: 0.63, p < 0.0001). However, there was no correlation between RadL and pathologic tumor size in patients with ypT0 and those with pathologic tumor size of ≤1.0 cm. Post-therapy RTS and RadV group correlated with ypT stage, tumor response grades using either CAP or MDA grading system, distance of superior mesenteric artery margin and tumor recurrence/metastasis.ConclusionAlthough RadL tends to understage ypT in PDAC patients who had no radiologically detectable tumor or small tumors (RTS0 or RTS1), radiologic measurement of post-therapy tumor size may be used as a marker for the pathologic tumor staging and tumor response to neoadjuvant therapy.     

High sensitive C-reactive protein-Effective tool in determining postoperative recovery in lumbar disc disease

Background:

It is common in medical practice to see patients having persistent pain and radiculopathy even after undergoing discectomy surgery. Inflammatory cytokines, such as interleukins are produced at the site of disc herniation and are now considered responsible for the pain perceived by the patient. This study has used high sensitive C-reactive protein (HSCRP) assay for predicting inflammation around the nerve roots on very same principle, which has used HSCRP for predicting coronary artery diseases in current clinical practice. Thus, purpose of this study is to test whether HSCRP can stand as an objective tool to predict postoperative recovery in patients undergoing lumbar discectomy. That is, to study association between preoperative HSCRP blood level and postoperative recovery with the help of modified Oswestry Back Disability Score.

Materials and Methods:

A study group consisting of 50 cases of established lumbar disc disease and control group of 50 normal subjects, matched with the study group. Both the study and control groups were subjected to detailed evaluation with the help of modified Oswestry Low Back Pain Scale both pre and postoperatively at 3 months, 6 months and 1-year. The preoperative blood samples were analyzed to assess the HSCRP concentration. All the cases underwent surgery over a period of 1-year by the same surgeon.

Results:

The level of HSCRP in the study group was between 0.050– and 0.710 mg/dL and in the control group, 0.005-0.020 mg/dL. There was highly significant positive correlation between preoperative HSCRP level and postoperative score at P < 0.005. Cases with HSCRP level in the range of 0.1820 ± 0.079 mg/dL, showed better recovery (score improved > 10 points), while those with HSCRP level in the range of 0.470 ± 0.163 mg/dL, showed poor recovery (score improved < 10 points).

Conclusion:

HSCRP will serve as a good supplementary prognostic marker for operative decision making in borderline and troublesome cases of lumbar disc disease.
