ABSTRACT

Primary prostatic lymphoma is an exceedingly rare entity comprising less than 0.09% of all prostatic cancers with follicular lymphoma making up only 12% as a subset. To our knowledge, primary follicular lymphoma co-existing with high grade prostatic adenocarcinoma presenting as a PI-RADS lesion 4 on mpMRI has not been previously described. We report the case of a 73-year-old male who presented with mildly elevated PSA and lower urinary tract symptoms. Prostate needle biopsy revealed low grade follicular lymphoma juxtaposed with high grade prostatic adenocarcinoma. The patient has been treated with radiation therapy for adenocarcinoma and is under observation for lymphoma progression.

ABSTRACT

OBJECTIVE: Endometrial cancer (EndoCA) is the most common gynecologic cancer and incidence and mortality rate continue to increase. Despite well-characterized knowledge of EndoCA-defining mutations, no effective diagnostic or screening tests exist. To lay the foundation for testing development, our study focused on defining the prevalence of somatic mutations present in non-cancerous uterine tissue. METHODS: We obtained ≥8 uterine samplings, including separate endometrial and myometrial layers, from each of 22 women undergoing hysterectomy for non-cancer conditions. We ultra-deep sequenced (>2000× coverage) samples using a 125 cancer-relevant gene panel. RESULTS: All women harbored complex mutation patterns. In total, 308 somatic mutations were identified with mutant allele frequencies ranging up to 96.0%. These encompassed 56 unique mutations from 24 genes. The majority of samples possessed predicted functional cancer mutations but curiously no growth advantage over non-functional mutations was detected. Functional mutations were enriched with increasing patient age (p = 0.045) and BMI (p = 0.0007) and in endometrial versus myometrial layers (68% vs 39%, p = 0.0002). Finally, while the somatic mutation landscape shared similar mutation prevalence in key TCGA-defined EndoCA genes, notably PIK3CA, significant differences were identified, including NOTCH1 (77% vs 10%), PTEN (9% vs 61%), TP53 (0% vs 37%) and CTNNB1 (0% vs 26%). CONCLUSIONS: An important caveat for future liquid biopsy/DNA-based cancer diagnostics is the repertoire of shared and distinct mutation profiles between histologically unremarkable and EndoCA tissues. The lack of selection pressure between functional and non-functional mutations in histologically unremarkable uterine tissue may offer a glimpse into an unrecognized EndoCA protective mechanism.

ABSTRACT

Cystic neutrophilic granulomatous mastitis (CNGM) is a distinct histopathologic entity characterized by neutrophilic and granulomatous inflammation surrounding clear cystic spaces. Rare gram-positive bacilli are sometimes identified within these cystic spaces. Studies in the literature have identified these gram-positive bacilli to be Corynebacterium species. We describe the clinicopathologic features of 7 cases of CNGM, including a case with evidence of Corynebacterium amycolatum. Patients were young to middle aged parous women ranging in age from 28 to 53 years (median age: 41 years). Gram-positive bacilli were identified in 4 cases, all within cystic spaces. Microbial culture from a 41-year old Hispanic woman grew Corynebacterium species on multiple occasions and Corynebacterium amycolatum was identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) on two separate occasions. Antibiotic susceptibility testing performed both times showed resistance to multiple antibiotics and susceptibility to vancomycin. Follow-up of all patients (range 3-12 months, median 6 months) showed a widely variable clinical course and varying response to a variety of treatment modalities. Five of the seven CNGM patients were parous, reproductive-aged Hispanic women who were born outside of the United States. Our findings further support the association of CNGM with corynebacteria and gram-positive bacilli. Furthermore, this study shows that Corynebacterium amycolatum, a nonlipophilic and multidrug-resistant corynebacterium can be associated with CNGM, hence the need for targeted antibiotic therapy. We propose identifying corynebacteria to the species level and performing antibiotic susceptibility testing in patients with CNGM because of the varied susceptibility testing profile that has been reported among different species of corynebacteria.

ABSTRACT

Paracoccidioides infection is a rare entity in the USA. This dimorphic fungus is found in Central and South America and is thought to be acquired by inhalation through the soil. We report a case of Paracoccidioides brasiliensis infection presenting as a clavicular bone lesion, peripancreatic mass, and various skin lesions. A 35-year-old man with a history significant for Hodgkin lymphoma presented with a left clavicular mass that was suspected clinically and radiologically as recurrent Hodgkin lymphoma. He was not experiencing any associated symptoms and was undergoing chemotherapy treatment for his known Hodgkin disease. On CT imaging, the mass was seen as a lytic bone lesion with an overlying soft tissue mass. This was biopsied and histologically diagnosed as a Paracoccidioides brasiliensis infection with associated necrotizing granulomatous inflammation. Also found on the CT scan was an enlarging peripancreatic mass which on endoscopic biopsy had similar histologic findings. In conclusion, this report presents a rare case of Paracoccidioides brasiliensis infection mimicking recurrent Hodgkin lymphoma.

ABSTRACT

We report an extremely rare case of primary glomus tumor of the esophagus, and review the corresponding literature. A 66-year-old female underwent a follow-up upper-gastrointestinal endoscopy due to dysphagia and previous history of esophageal lump. Endoscopic ultrasonography revealed a mass involving the deep mucosa and submucosa (Layers 2 and 3). Endoscopic biopsy revealed a mesenchymal tumor composed of nest of epithelioid cells with associated small blood vessels proliferation. Immunohistochemically, the tumor cells were positive for alpha smooth muscle actin and vimentin, but negative for c-kit and the vascular stroma was highlighted by positivity with CD34. Pathological examination confirmed that the tumor was a glomus tumor of the esophagus. The patient remains healthy without any recurrence to date.

ABSTRACT

Pleural involvement in lymphoma is rare as the initial presentation of disease in the immunocompetent patient. We describe a rare case of primary, isolated pleural B-cell lymphoma in a 75-year-old female, previously treated for adenocarcinoma of the left lung with lobectomy and chemotherapy, who presented with shortness of breath. A CT scan of the chest revealed a right-sided pleural effusion and pleural thickening. She underwent multiple nondiagnostic thoracenteses. A subsequent surgical biopsy was diagnostic of large B-cell lymphoma.

ABSTRACT

Serous ovarian cancer (SEOC) is the deadliest gynecologic malignancy. MicroRNAs (miRNAs) are a class of small noncoding RNAs which regulate gene expression and protein translation. MiRNAs are also encoded by viruses with the intent of regulating their own genes and those of the infected cells. This is the first study assessing viral miRNAs in SEOC. MiRNAs sequencing data from 487 SEOC patients were downloaded from the TCGA website and analyzed through in-house sequencing pipeline. To cross-validate TCGA analysis, we measured the expression of miR-H25 by quantitative immunofluorescence in an additional cohort of 161 SEOC patients. Gene, miRNA expression, and cytotoxicity assay were performed on multiple ovarian cancer cell lines transfected with miR-H25 and miR-BART7. Outcome analysis was performed using multivariate Cox and Kaplan-Meier method. Viral miRNAs are more expressed in SEOC than in normal tissues. Moreover, Herpetic viral miRNAs (miR-BART7 from EBV and miR-H25 from HSV-2) are significant and predictive biomarkers of outcome in multivariate Cox analysis. MiR-BART7 correlates with resistance to first line chemotherapy and early death, whereas miR-H25 appears to impart a protective effect and long term survival. Integrated analysis of gene and viral miRNAs expression suggests that miR-BART7 induces directly cisplatin-resistance, while miR-H25 alters RNA processing and affects the expression of noxious human miRNAs such as miR-143. This is the first investigation linking viral miRNA expression to ovarian cancer outcome. Viral miRNAs can be useful to develop biomarkers for early diagnosis and as a potential therapeutic tool to reduce SEOC lethality.

ABSTRACT

Primary adrenal leiomyosarcoma has been reported previously in 25 patients. The patient presented herein is the only case where the definitive diagnosis was made with core needle biopsy evaluation. A 45-year-old male presented with pain in the back and right groin. Radiological evaluation demonstrated a heterogeneous 11 cm right adrenal mass, multiple liver masses, and an enlarged aortocaval lymph node. No retroperitoneal mass was identified. Core needle biopsies revealed a malignant mesenchymal neoplasm composed of atypical spindle shaped cells arranged in intersecting fascicles, with high mitotic activity and focal tumor necrosis. Immunohistochemical stains revealed immunoreactivity for smooth muscle actin and desmin. S-100 and c-kit stains were negative. The diagnosis of adrenal leiomyosarcoma with liver metastasis was rendered. It was an aggressive tumor with clinical presentation at Figure 1. Core needle biopsy, a an advanced stage. Definitive diagnosis of this tumor by core needle biopsy can obviate the need for surgical biopsy in patients with advanced disease.

ABSTRACT

CRC cancer is one of the deadliest diseases in Western countries. In order to develop prognostic biomarkers for CRC (colorectal cancer) aggressiveness, we analyzed retrospectively 267 CRC patients via a novel, multidimensional biomarker platform. Using nanofluidic technology for qPCR analysis and quantitative fluorescent immunohistochemistry for protein analysis, we assessed 33 microRNAs, 124 mRNAs and 9 protein antigens. Analysis was conducted in each single dimension (microRNA, gene or protein) using both the multivariate Cox model and Kaplan-Meier method. Thereafter, we simplified the censored survival data into binary response data (aggressive vs. non aggressive cancer). Subsequently, we integrated the data into a diagnostic score using sliced inverse regression for sufficient dimension reduction. Accuracy was assessed using area under the receiver operating characteristic curve (AUC). Single dimension analysis led to the discovery of individual factors that were significant predictors of outcome. These included seven specific microRNAs, four genes, and one protein. When these factors were quantified individually as predictors of aggressive disease, the highest demonstrable area under the curve (AUC) was 0.68. By contrast, when all results from single dimensions were combined into integrated biomarkers, AUCs were dramatically increased with values approaching and even exceeding 0.9. Single dimension analysis generates statistically significant predictors, but their predictive strengths are suboptimal for clinical utility. A novel, multidimensional integrated approach overcomes these deficiencies. Newly derived integrated biomarkers have the potential to meaningfully guide the selection of therapeutic strategies for individual patients while elucidating molecular mechanisms driving disease progression.

ABSTRACT

Ovarian cancer is the most lethal gynecologic malignancy. Recently, NACT (Neo Adjuvant Chemotherapy) has been tested as alternative approach for the management of ovarian cancer patients. A biological predictor helpful in selecting patients for NACT would be desirable. This study was aimed at identifying actionable mechanisms of resistance to NACT. Expression of a panel of microRNAs was screened in a discovery set of 85 patients. Analysis of the potential targets was conducted in the same RNAs by calculating significant correlations between microRNAs and genes. Quantitative fluorescent immunohistochemistry was employed in a validation set of 109 patients. MiR-193a-5p was significantly overexpressed in the NACT setting. Analysis of its potential targets demonstrated that this microRNA is also significantly correlated with HGF and MET genes. Analysis of protein expression in samples taken before and after NACT demonstrated that both HGF and c-Met are increased after NACT. Patients who relapse shortly after NACT exhibited the highest relative basal expression of both HGF and c-Met, while the opposite phenomenon was observed in the best responders. Mir-193a-5p, HGF and c-Met expression may help select eligible patients for this modality of treatment. Moreover, inhibitors of this pathway may improve the efficacy of NACT.

ABSTRACT

BACKGROUND: MicroRNAs in solid malignancies can behave as predictors of either good or poor outcome. This is the case with members of the miR-200 family, which are the primary regulators of the epithelial to mesenchymal transition and have been reported to act as both oncogenes and tumor suppressors. This study assessed the role of miR-200c as regulator of class III ß-tubulin (TUBB3), a factor associated with drug-resistance and poor prognosis in ovarian cancer. METHODS: Expression of miR-200c was assessed in a panel of ovarian cancer cell lines with inherent or acquired drug-resistance. Stable overexpression of miR-200c was obtained in A2780 and Hey cell lines. Crosslinking-coupled affinity purification method and ribonucleic-immunoprecipitation assay were used to characterise the complexes between miR-200c, HuR and 3'UTR region of TUBB3 mRNA. Nanofluidic technology and immunohistochemistry were used to analyze the expression of HuR, TUBB3 and miR-200c in 220 ovarian cancer patients. RESULTS: In a panel of ovarian adenocarcinoma cell lines, we observed a direct correlation between miR-200c expression and chemoresistance. In A2780 cells miR-200c targeted TUBB3 3'UTR, while a positive correlation was observed between miR-200c and TUBB3 expression in most of the other cell lines. Through the analysis of 3'UTR-associated complexes, we found that the miR-200c can increase the association of the RNA binding protein HuR with TUBB3 mRNA, whereas HuR binding enhanced TUBB3 mRNA translation. Most importantly, in our analysis on 220 ovarian cancer patients we observed that overexpression of miR-200c correlated with poor or good outcome depending on the cellular localization of HuR. CONCLUSION: This study suggests a model for the combined regulatory activity of miR-200c and HuR on TUBB3 expression in ovarian cancer. When HuR is nuclear, high expression of miR-200c inhibits TUBB3 expression and results in a good prognosis, whereas when HuR occurs in cytoplasm, the same miRNA enhances TUBB3 expression and produces a poor outcome. These findings reveal the usefulness of multidimensional analysis in the investigation of the prognostic role of miRNA expression.

ABSTRACT

PURPOSE: Colorectal cancer is one of the deadliest diseases in Western countries. To predict the outcome of therapy, we assessed the role of class III (TUBB3) and class V ß-tubulin (TUBB6) as predictive biomarkers. EXPERIMENTAL DESIGN: Using immunohistochemistry and nanofluidics, the expression of TUBB3 and TUBB6 was assessed in two cohorts of 180 and 134 patients, respectively. The CYP17A1 RS743572 was genotyped to identify GG carriers with enhanced androgen levels. TUBB3 and TUBB6 were investigated in 22 colorectal cancer cell lines in basal conditions and after serum starvation, the latter serving as activator of this prosurvival pathway. To ascertain the role of androgen receptor (AR) in such regulation, we silenced AR and checked TUBB3 and TUBB6 expression and sensitivity to chemotherapy. RESULTS: There was a link between poor survival, the expression of TUBB3/TUBB6, and AR only in females. Conversely, only in males carriers of the GG phenotype exhibited the worst outcome. Importantly, male cell lines were resistant to serum starvation and exhibited higher levels of TUBB6, thereby suggesting that the pathway is activated by androgens. In female cells this phenomenon was absent. In both genders, AR was the main driver of TUBB3/TUBB6 expression, as constitutive silencing of AR was associated with downregulation of TUBB3/TUBB6 expression and increased sensitivity to oxaliplatin and SN-38. CONCLUSIONS: The involvement of androgens in the TUBB3 pathway opens the way for clinical trials to assess the efficacy of antiandrogens for increasing the efficacy of chemotherapy in male colorectal cancer patients.

ABSTRACT

Malignant transformation of eccrine spiradenoma is extremely rare. We describe the case of a 70-year-old man with malignant eccrine spiradenoma of the forearm and metastases to the axillary lymph nodes. Surgical excision with adequate margins and lymph node dissection was performed. Tamoxifen therapy was instituted after obtaining positive immunostaining results for estrogen receptor. After 41 months of follow-up, there has been no recurrence or distant metastases. Wide local excision and close follow-up are crucial in the management of malignant eccrine spiradenoma. The role of other therapeutic modalities, including hormonal therapy, remains to be determined.
