Abstract Objectives Prostate adenocarcinoma (PCa) accounts for considerable morbidity in aging men in Africa. With fewer studies reporting on PCa within the subregion, this study was set out to analyze various clinicopathological patterns in PCa lesions, providing additional data for comparison with reported PCa cases in other parts of the globe. Methods The study included prostatic adenocarcinoma tissues received in the Department of Pathology, Komfo Anokye Teaching Hospital, over a period of 6 years (from 2008 to 2013). Relevant clinical data including age, histopathological diagnosis, and Gleason’s microscopic grading were extracted from the surgical day book of the department. In a consecutive order, archived tissue blocks and slides of the selected cases were also retrieved for review and confirmation of diagnosis. Results Mean age at presentation was 71.7 ± 8.72 years (age ranged from 53 to 96 years) with a peak in the seventh decade of life (n = 41, 52.6%). Majority of the cases were poorly differentiated (n = 43, 55.1%), followed by moderately differentiated (n = 20, 25.6%) and well-differentiated samples (n = 15, 19.2%). Highest occurrence of prostate adenocarcinoma was recorded in the year 2009 (n = 46), followed by 2008 and 2009 (n = 16 and 13, respectively), together accounting for 96.2% of the cases reported. Conclusion Histopathological evaluation of prostatic biopsies remains the mainstay of diagnosing prostate adenocarcinoma in Ghana. The pattern of incidence in the population is in line with several reported studies, with majority of the cases diagnosed at the late stage of the disease and thus portending worse prognosis.

Histopathological Results

<b><i>Purpose:</i></b> To evaluate the histopathological characteristics of clinically advanced retinoblastoma (RB) and its relationship with tumor differentiation. <b><i>Methods:</i></b> This was a cross-sectional study of primary enucleated group D/E intraocular RB using medical records from 2017 to 2020 in a tertiary referral hospital. Cases with incomplete histopathological results were excluded. Tumors were classified into well, moderately, and poorly differentiated and undifferentiated. High-risk histopathological features were classified as per Thaung and Karaa [<i>Community Eye Health</i>. 2018;31(101):17–3]. <b><i>Results:</i></b> This study included 121 patients (129 eyes), of which 32.2% were diagnosed at 25–36 months. High-risk features (HRFs) were found in 100/129 eyes, and of 73 complete histopathological results, the 2 most common HRFs were postlaminar optic nerve invasion and massive choroidal invasion. RB was poorly differentiated in 69.9% and well differentiated in 12.3% of eyes. There was no statistically significant association between any HRFs and tumor differentiation, with age &#x3e;2 years associated with tumor differentiation (<i>p</i> &#x3c; 0.05). <b><i>Conclusion:</i></b> The frequency of HRFs is 77.5% of primary enucleated eyes, mainly poorly and undifferentiated cells, particularly in children aged &#x3e;2 years old.

AbstrakKanker prostat merupakan kanker kedua terbanyak pada pria di seluruh dunia. Tujuan penelitian ini adalah untuk mengetahui faktor prognostik adenokarsinoma prostat seperti derajat histopatologi berdasarkan the 2005 ISUP modified Gleason system, invasi perineural dan kadar PSA serum sebelum operasi. Ini adalah suatu penelitian deskriptif kasus adenokarsinoma prostat yang didiagnosis di laboratorium patologi anatomi periode 2010-2012. Data usia dan kadar PSA diperoleh dari rekam medik. Review sediaan histopatologi dilakukan untuk konfirmasi skor Gleason, lalu dikelompokan berdasarkan derajat histopatologi. Kasus adenokarsinoma prostat yang memenuhi kriteria inklusi adalah 163. Hasil penelitian menunjukkan kasus adenokarsinoma prostat terbanyak pada kelompok usia 61-70 tahun sebanyak 38,65%, derajat histopatologi poorly differentiated yaitu 46,63%, invasi perineural 22,7% dan 83,33% kadar PSA serum >20 ng/ml. Pada kelompok usia 51-60 tahun adenokarsinoma prostat terbanyak ditemukan dengan derajat histopatologi well differentiated; sedangkan kelompok usia 61-70 tahun, 71-80 tahun dan 81-90 tahun terbanyak poorly differentiated. Invasi perineural positif terbanyak pada derajat histopatologi poorly differentiated. Semua derajat histopatologi adenokarsinoma prostat menunjukkan kadar PSA serum terbanyak >20 ng/ml. Penelitian ini menunjukkan kecenderungan peningkatan usia, invasi perineural dan kasus dengan kadar PSA serum >20 ng/ml bersamaan dengan peningkatan derajat histopatologi adenokarsinoma prostat.AbstractProstate cancer is the second most common cancer in men around the world. The objective of this study was to determine prognostic factors of prostate adenocarcinoma such as histopathological grading based on the 2005 ISUP modified Gleason system, perineural invasion, and PSA serum. This was a descriptive study of prostate adenocarcinoma diagnosed in Pathology Department from 2010 to 2012. The age and PSA serum level were taken from the medical records. The histological slides were reviewed to confirm Gleason score, and then classified into the histopathological grading. The number of prostate adenocarcinoma cases included in this study was 163. The result shows that the majority of cases were found at 61–70 years old (38.65%), histopathological grading was mostly poorly differentiated (46.63%), positive perineural invasion 22.7% and 83.33% PSA serum above 20 ng/ml. Prostate adenocarcinomas found at age 51-60 years old were mostly well differentiated. On the other hand, cases found at age above 60 years old were mostly poorly differentiated. Perineural invasion was mostly found on poorly differentiated cases. All of histopathological grading showed PSA serum above 20 ng/ml. This study suggested that higher age, perineural invasion and PSA serum level above 20 ng/ml were congruent with the histopathological grading.

Reduced Mobility

In Acute Lymphocytic Leukemia motility of lymphocytes is associated with dissemination of malignancy and establishment of metastatic foci. Normal and leukemic lymphocytes in circulation reach solid tissues where due to in adequate perfusion some cells get trapped among tissue spaces. Although normal lymphocytes reenter into circulation leukemic lymphocytes are thought to remain entrapped owing to reduced mobility and form secondary metastasis. Cell surface, transmembrane interactions, cytoskeleton and level of cell differentiation are implicated in lymphocyte mobility. An attempt has been made to correlate ultrastructural information with quantitative data obtained by Laser Doppler Velocimetry (LDV). TEM of normal & leukemic lymphocytes revealed heterogeneity in cell populations ranging from well differentiated (Fig. 1) to poorly differentiated cells (Fig. 2). Unlike other cells, surface extensions in differentiated lymphocytes appear to originate by extrusion of large vesicles in to extra cellular space (Fig. 3). This results in persistent unevenness on lymphocyte surface which occurs due to a phenomenon different from that producing surface extensions in other cells.

Background and aim: HER2 overexpression by immunohistochemistry is a prognostic maker in gastric cancer and helps to select candidates benefitted from targeted therapy with trastuzumab. This study is aimed at the assessing HER2 overexpression and its relationship with endoscopic and histopathological findings of gastric adenocarcinoma. Objectives and methods: Biopsy samples from 92 gastric cancer patients were examined for HER2 status by immunohistochemical staining. Results: 6.5% of tumors were cardia tumors and 93.5% were non-cardia tumors. Using the Lauren classification, 51.1% were intestinal type and 48.9% were diffuse type. Using WHO classification, 54.3% were tubular adenocarcinoma, 7.6% were mucinous adenocarcinoma, 15.2% were signet-ring cell carcinoma, and 22.8% were undifferentiated carcinoma. 32.6% were well-differentiated, 15.2% were moderately-differentiated, and 52.2% were poorly-differentiated carcinoma. HER2 was positive in 20.7% of gastric carcinomas, 50% cardia tumors and 18.6% non-cardia tumors. HER2 positivity among polypoid, fungating, ulcerated, and infiltrative types were 38.5%, 29.7%, 9.1% and 0%, respectively. HER2 overexpression in intestinal type was higher than that in diffuse type (31.9% vs. 8.9%, p = 0.009). HER2 overexpression in tubular adenocarcinoma, mucinous adenocarcinoma, signet-ring cell carcinoma, and undifferentiated carcinoma was 28.0%, 14.3%, 7.1% and 14.3%, respectively. HER2 overexpressions were different between differentiation degrees: 30% of well-differentiated tumors, 35.7% moderately-differentiated tumors, and 10.4% of poorly-differentiated tumors (p = 0.037). Conclusions: HER2 overexpression was found in 20.7% of endoscopic biopsy sample of gastric adenocarcinoma and was associated with endoscopic gross characteristic, Lauren histologic type and differentiation degree.

We present a case of a 64-year-old man who presented with a rapidly growing tumor in the left buttock and intergluteal cleft area, which was affected by hidradenitis suppurativa. The patient was on tumor necrosis factor-alpha inhibitors for hidradenitis suppurativa for 2 years prior to the development of the mass. Initial biopsy of the mass showed a well-differentiated squamous cell carcinoma with spindle cells and positive epithelial immunomarkers. Subsequent excisional biopsy of the tumor showed an infiltrating poorly differentiated squamous cell carcinoma composed of islands of atypical sarcomatoid spindle cells. Squamous cell carcinoma arising in hidradenitis suppurativa is a rare complication which may occur secondary to chronic inflammation and epidermal hyperproliferation in hidradenitis suppurativa–affected areas.

BackgroundThe use of immune checkpoint inhibitors (ICIs) in cancer treatment has been approved by the FDA, but its application is experimental in the treatment of papillary thyroid cancer (PTC). Induction of immune response via recognition of neoantigens is considered to be the basis for the treatment mechanism of ICIs.1 However, the neoantigen landscape has not been explored in PTC. Our aim is to investigate the immune landscape of PTC in relation to neoantigens, taking into account the BRAF mutation status and grade of differentiation as contributing factors.MethodsBRAF V600E mutation status and thyroid differentiation scores (TDSs) were gathered from the PTC cohort of The Cancer Genome Atlas (TCGA). TDS was derived from the mRNA expression levels of 16 thyroid function genes to quantify the grade of differentiation. Tumors with TDSs in the 1st quartile and 4th quartile were defined as poorly differentiated and well differentiated, respectively. The neoantigen burden for each sample was predicted using CloudNeo pipeline. The infiltration of immune cells was calculated through CIBERSORT.ResultsAmong 400 patients with predicted neoantigen data, 187 (47%) had BRAF mutations. The BRAF mutated tumors showed increased cytolytic activity score (CYT, p=0.001), increased infiltration of regulatory T cells (Treg, p<0.001), and higher PD-L1 expression (p<0.001) compared to BRAF wild-type tumors (figure 1). In regard to grade of differentiation, poorly differentiated tumors showed increased CYT (p=0.002), increased infiltration of Treg (p<0.001), and higher PD-L1 expression (p<0.001) compared to well differentiated tumors (figure 2). However, BRAF mutation status or grade of differentiation did not correlate with the neoantigen burden. Also, the neoantigen burden did not show any correlations with immune landscape features such as infiltration of CD8+ T cells or Treg, CYT, and PD-L1 expression.Abstract 752 Figure 1Immune traits according to BRAF mutation status.

(a) Cytolytic activity score(CYT). (b) Infiltration of regulatory T cells(Tregs). (c) PD-L1 expression.ConclusionsIncreased CYT and higher expression of PD-L1 in the BRAF mutated or the poorly differentiated tumors imply the possible role of ICI use in these subgroups of patients. However, the immune response to these subgroups does not seem to be mediated through the increase in neoantigen formation. Further studies are warranted to explore markers for immunotherapy implication.ReferencesSchumacher TN, Schreiber RD, Neoantigens in cancer immunotherapy. Science 2015; 348:69–74.

Breast carcinoma is among the most common malignancy in women. Abstract:Original ArticleAim of the present study was to evaluate the prognostic signicance of iron expression in the biopsies of patients with breast cancer Objective:24 breast biopsies were studied. 19 cases were poorly differentiated, 5 cases were moderately differentiated and there was no well differentiated case. Iron, Estrogen receptor (ER), Progesterone receptor (PR), HER2 and Ki-67 immunohistochemical staining was performed for all these cases. Methods: Among the 5 moderately differentiated cases, 3 (60%) were positive for iron staining and among 19 poorly differentiated cases, 11 cases (57.89%) were positive. More iron positive cases (7 out of 14) were triple positive belonging to Luminal B class. Out of 14 iron positive cases, 11 were positive for HER2, 10 for ER, 9 for PR and all positive for Ki-67. Results: Iron deciency in premenopausal and overload in post-menopausal women can contribute to the development of breast carcinoma. So, iron can be considered as a cheap and effective marker for the prognosis of breast cancer. Association between a rise in iron levels and HER2 expression may provide new strategy for breast cancer treatment.
