Epidemiological and Histopathological Profile of Gastric Adenocarcinoma at Brazzaville University Hospital

Introduction: Gastric adenocarcinoma is the most common gastric malignancy (over 90% of gastric cancers) and remains a global public health problem. The aim of the study was to determine the epidemiological and histopathological aspects of gastric adenocarcinoma in Brazzaville. Material and Methods: The epidemiological and histopathological profile is determined through a descriptive study, collecting retrospective data spread over a period of 11 years (January 2008- December 2018), based on consultation of the departmental histology registers. pathological anatomy and cytology. For each case, age, sex, location, pTNM stage, location and histological type were collected. Results: 93 histologically confirmed gastric adenocarcinomas were collected during the 11-year period. The mean age of the patients was 54.5 years. The sex ratio was 2 in favor of men. The antral and fundal localization were more frequent (74.2% and 20.4% respectively). Of the 2 operative parts collected, one was T2N1 and the other T1N0. Tubular adenocarcinoma was the most common histologic type (51.6%), followed by independent cell adenocarcinoma (34.4%), papillary adenocarcinoma (11.8%), and mucinous adenocarcinoma (2, 2%). Conclusion: gastric tubular adenocarcinoma was the most common histological type in Brazzaville. Key words: epidemiology, gastric adenocarcinoma, histological type.

A systematic review of post-transplant lymphoproliferative disorder after renal transplantation.

e19577 Background: Post Transplant Lymphoproliferative Disorder (PTLD) is a rare but severe complication following renal transplant. This study aims to explore the treatment modalities, histological types, and risk factors related to PTLD. Methods: Following the PRISMA guideline, we searched the literature on PubMed, Cochrane, Embase & clinicaltrials.gov. A total of 1741 articles were screened and 16 studies were included. Results: We reviewed 275915 adult patients who underwent renal transplantation out of which 2484 (0.9%) patients developed PTLD. Data for gender shows that 61.1% were males and 38.9% females. 576/2484 (23%) cases were EBV positive post-transplant. Seven studies showed the median duration from transplant to the development of PTLD was 80 months (5m-22yrs). Monomorphic PTLD was reported in 585 cases as the most common histological type. 5 studies suggested mortality due to PTLD was 41.38%. OS at 5 and 10 years was 55% and 41% respectively. Conclusions: Our study shows that PTLD is a rare complication after renal transplant which was more common in males. EBV did not show association with PTLD. Monomorphic is the most common histological type of PTLD after renal transplant. Our results show that it is associated with significantly high mortality. [Table: see text]

Recurrent Struma Ovarii Presented with High Levels of Thyroglobulin

Struma ovarii are rare ovarian tumors, of monodermal germ cell origin, containing predominantly thyroid tissue. They are typically benign unilateral pelvic masses. Among the rare cases of malignancy, the most common histological type is that of the papillary carcinoma. A definite preoperative diagnosis of these tumors is difficult to achieve since most imaging findings are generally nonspecific. A rare exception is the case of synchronous abnormal thyroid blood tests where an ovarian teratoma should be highly suspected, especially when no pathology of the thyroid gland coexists. Surgical excision is the mainstay of treatment. Taking into account that struma ovarii are mainly encountered in patients of a childbearing age, a conservative surgical approach is a reasonable option. We present the case of a 56-year-old woman who was diagnosed with both a primary and recurrent struma ovarii while investigating the incidental finding of elevated blood laboratory levels of the thyroglobulin (Tg).

Invasive Squamous Cell Carcinoma of the Cervix in Pregnancy: A Case Report

Cervical squamous cell carcinoma is the most common histological type of carcinoma in the uterine cervix, but during pregnancy is relativity uncommon, with an incidence of 0.8 to 1.5 cases per 10,000 births. Cervical squamous cell carcinoma is the leading cause of death among women aged 35 to 54 years and the second most common cause among women aged 15 to 34 years after breast carcinoma. Most patients are diagnosed at an early stage of the disease, probably due to routine prenatal screening. The occurrence of invasive cervical carcinoma is relatively uncommon in pregnant women. However, cancer treatment during pregnancy currently remains one of the main and biggest therapeutic challenges in cervical cancer. The therapeutic approach should be customized and depends mainly on histology, disease stage, and gestational age. We present a case concerning a 26-year-old woman with invasive moderately differentiated keratinizing squamous cell cervical carcinoma, stage pT2b, N1, M0/ FIGOIIB, during pregnancy (4th lunar month).

A Retrospective Analysis of Breast Cancer at BPKMCH, Nepal

Introduction: Breast cancer is the most common cancer and also the leading cause of cancer related mortality in women worldwide which impact 2.1 million women each year. Breast cancer rates are increasing in nearly every region globally. Methods: This was retrospective study at Department of Pathology in B P Koirala Memorial Cancer Hospital effective from 15 April 2018 to 14 April 2019. All the data were retrieved and analyzed. Results: Total 205 breast cancer cases were analyzed, among them 198 cases were females accounting 96.5 %and 7 cases were males accounting 3.5 %.Among 205 cases, 181 (88.6%) cases were invasive ductal Carcinoma No Special Type. Majority of cases 111(54%) were diagnosed with Nottingham grading system grade II of breast cancer. According to our study breast cancer was most common in the age group 41-50 years (32.2%). Conclusion: Breast cancer is more common in females than in males. Most common affected age group was 41-50 years. Most common histological type was invasive ductal carcinoma NST. Similarly, left sided breast cancer was more common than right.

Modern treatment of vulvar cancer

BackgroundVulvar cancer accounts for 3–5% of malignant diseases of the female genital tract. The Slovenian incidence rate is 5.5/100,000, which means 57 new cases per year. The most common histological type (90%) is squamous cell carcinoma. Based on etiology, it can be classified into the first type which correlates with human papillomavirus (HPV) infection and the second type which is not associated with HPV. The most common and long-lasting symptom of vulvar cancer is pruritus. The preferred diagnostic procedure to confirm the diagnosis is a punch or incision biopsy. Surgery in combination with radiotherapy is the standard treatment for vulvar cancer. Sentinel lymph node biopsy with lymphoscintigraphy is now a standard part of surgical treatment. Chemotherapy is a palliative treatment option.ConclusionsVulvar cancer is a rare disease. Because of the pathogenesis, surgery and radiotherapy are the main treatment modalities. The sentinel node biopsy (SNB) represents a contemporary approach to the vulvar cancer treatment and significantly reduces morbidity. Improvements in treatment of vulvar cancer contributed to the decrease of mortality among Slovenian women.

Experiencia Quirúrgica en el Manejo del Cáncer de Recto. Hospital de SOLCA, Guayaquil – Ecuador

BACKGROUND: Colorectal cancer is the third most common among malignant neoplasms worldwide. Treatment choice depends on the location of the tumor, among other factors, and varies from local excision to abdominoperineal resection, adjuvant or neoadjuvant therapy can be needed, depending on clinical stage. The purpose of this study was to determine the most common histological type of rectal cancer, establish the most frequent clinical stage at diagnosis, the most common surgical technique and complications. METHODOLOGY: A cross-sectional study was carried out, with 160 patients treated in the digestive surgery service of Hospital SOLCA, Guayaquil – Ecuador, between January 2011 and December 2016, with colorectal cancer histologically diagnosed and treated surgically. RESULTS: Female sex was the most affected, with 65.7%, 63.1% of the patients were diagnosed at stage III, adenocarcinoma was the most common histological type (73.7%), the tumor was more frequently located at a low level, in 67.5% of the patients. Surgery was scheduled for 83.7% of the patients, derivative colostomy was the most common surgical procedure for treatment (48.8%), and the most common complications were those related to the ostomy, in 9.4% of the patients. Immediate mortality was 1.2% and late mortality was 8.1%. CONCLUSION: This study evidenced that colorectal cancer affected with more frequency to women, mainly to people over 60 years old. Most of the patients were diagnosed with advanced clinical stage (III) carcinoma, most frequently adenocarcinoma. Derivative colostomy was the procedure of choice for most of the patients, most of them needed neoadjuvant therapy too. The most common postsurgical complications were those related to ostomies.

Analysis of Let-7 Family miRNA in Plasma as Potential Predictive Biomarkers of Diagnosis for Papillary Thyroid Cancer

The most common histological type of thyroid cancer is papillary thyroid carcinoma (PTC). Radical resection of the thyroid gland is currently the recommended method of treatment. Almost 75% of thyroidectomies performed just for diagnostic purposes are benign. Thus, the confirmation of innovative and more precise noninvasive biomarkers holds promise for the detection of PTC, which may decrease the number of unnecessary thyroid lobectomies. In this work, using the droplet digital PCR (ddPCR) method, we have analyzed the level of five miRNAs (let-7a, let-7c, let-7d, let-7f, and let-7i) in the plasma of patients with PTC and compared them with those of a healthy control group to investigate whether miRNAs also have value in the management of PTC. Levels of four miRNAs, namely let-7a, let-7c, let-7d, and let-7f, were significantly higher in PTC patients than healthy controls. Thus, the analysis of circulating let-7 can be a useful tool and support the currently used methods for PTC diagnosis. However, our observation requires further research on a larger patient group.
