Relationship between age and the histopathological features to chemotherapy response in colorectal cancer patients: a prospective observational study

Introduction: Chemotherapy response in early age-onset colorectal cancer patients is still controversial, and the results of chemotherapy response are unknown. Therefore, the purpose of this study is to determine the relationship between the age of colorectal cancer patients and histopathological features and chemotherapy response. Methods: This is a prospective observational study. The subjects in this study were colorectal cancer patients in the Digestive Surgery division at Tertiary Hospital in West Java from September 2021 to September 2022. Results: There were 86 subjects who underwent chemotherapy in accordance with the inclusion and exclusion criteria. Consisting of 39 patients of early age onset and 44 female patients. The most common histopathological feature in early age onset (EAO) and late age onset (LAO) was adenocarcinoma (25% and 46%, respectively). Stage III colorectal cancer affected 38 patients, while stage IV affected 48 patients. There was a significant relationship between early age onset and late age onset with histological features (p < 0.001). The patients with the highest chemotherapy response had stable diseases in EAO (17 patients) and LAO (20 patients). There was no statistically significant relationship between age, histological features, and stage of colorectal cancer and chemotherapy response (p > 0.05). The results of the ordinal logistic regression test showed no systematic relationship between chemotherapy response and age, histopathological features, gender, or cancer stage (p > 0.05). Conclusion: There was no association between age and histopathologic features with chemotherapy response and there is no difference in chemotherapy response between early and late age onset. (AU)

A clinicopathological study of granulosa cell tumors of the ovary: Can morphology predict prognosis?

Objective: Granulosa cell tumors (GCT) are low-grade malignant sex cord-stromal tumors (SCST) with late metastasis/recurrences and long disease-free periods. We performed a clinicopathological evaluation of GCT to ascertain features having prognostic impact. Materials and Methods: All cases of GCT of ovary from January 2006 to December 2018 were assessed for architectural patterns, nuclear grooves, and Call-Exner bodies. Each feature was graded on frequency of occurrence: not present (0)–very frequent (3). Anisonucleosis, necrosis, and inflammation were noted. Cases were grouped on mitotic count; <10 mitosis/10 High power field (HPF) or >=11 mitoses/10 HPF and Ki-67 index; <10% Ki-67 and >=11% Ki-67. Results: GCT formed 60.1% of SCST. Sixty cases' ages were in the range of 15–78 years (median 45). Clinical details were available in 37. Commonest presentation was abnormal uterine bleeding. Serum CA125 was raised in 16.1% and Inhibin in 58.8%. Seventy percent were in stage I. Disease recurrence was associated with higher stage (P = 0.007). The most frequent pattern was diffuse sheets (47%). Call-Exner bodies were absent in 22.2%. Grooves with score 1, 2, and 3 were seen in 35.8%, 23.5%, and 13.6%, respectively. Anisonucleosis was present in 26.7%, necrosis in 11.1%, and lympho-plasmacytic infiltrate in 43%. Out of total, 93.3% had <10 mitosis/10 HPF and 43.2% had recurrence, most with high Ki-67 (P = 0.064). Conclusion: Our study outlines histomorphological spectrum of GCT and emphasizes its frequent occurrence in lower stages with late recurrences. The presence of grooves may indicate granulosa-cell origin. Call-Exner bodies are not a necessity. Histomorphological features are not prognostically important. However, prognostic value of Ki-67 cannot be excluded. Limitation of the study was a small number of cases with follow-up.

Breast cancer is a heterogeneous disease with high incidence among women, being the leadingcause of cancer death. Among the host microenvironment processes that contribute tocarcinogenesis, angiogenesis plays a central role, and the Vascular Endothelial Growth FactorA (VEGFA) is the main pro-angiogenic factor, with impact in the development of breastcancer. The gene encoding VEGFA is highly polymorphic, and their polymorphisms have beenassociated with different patterns of gene expression, affecting VEGFA levels in different cellmodels, including breast cancer. The present study aimed to investigate the associationbetween single nucleotide polymorphism (SNP) of VEGFA (rs699947, rs833061, rs1570360,rs2010963 and rs3025039) and histopathological features with prognostic value in breastcancer, and to evaluate the potential of VEGFA genotypes and haplotypes as risk predictors ofdisease progression. The study population consisted of a cohort of Brazilian women withunilateral and non-metastatic breast cancer, who underwent tumor resection or neoadjuvantchemotherapy as their first therapeutic approach (N=1043). Genomic DNA was extracted fromperipheral blood samples, and used for VEGFA genotyping (N=895). The results were dividedinto two manuscripts...

Objective To explore the histopathological features of 850 patients with esophageal malignant tumor in 10 years.Methods From January 2002 to January 2012, 850 patients diagnosed with esophageal malignant tumor were enrolled.Tumor location, general type, pathological type and TNM stage were retrospectively analyzed.All the data were described as case number and percentage.Results Among the 850 cases of esophageal malignant tumor, 33 lesions (3.9％) located in the neck segment of esophagus, 119 lesions (14.0％) located in the upper segment, 44 lesions (5.2 ％) located in the upper-middle segment, 409 lesions (48.1％) located in the middle segment, 123 lesions (14.5 ％) located in the middle-lower segment, 122 lesions (14.4％) located in the lower segment.Among the 724 eases clearly diagnosed as esophageal malignant tumor by general type, the most cases were ulcer type (305 cases, 42.1％), followed by medulla type (260 cases, 35.9％), fungating type (80 cases, 11.0％) and constrictive type (70 cases, 9.7％), and the least cases were intraluminal type (nine cases, 1.2％).Among the 850 cases of esophageal malignant tumor, squamous cell carcinoma (794 cases, 93.4 ％) was the most common cytological type, followed by small cell carcinoma (19 eases, 2.2％), and the least common cytological type was adenocarcinoma (seven cases, 0.8 ％).Among the 724 cases with clear TNM staging, case number of Tis, T1, T2, T3 and T4 stage was eight (1.1％), six (0.8％), 271 (37.4％), 278 (38.4％) and 161 (22.2％), respectively.Among the 122 cases of distal esophageal carcinomas (104 cases with clear TNM staging), most cases were squamous cell carcinoma (112 cases, 91.8 ％), the others cases were adenocarcinoma (three cases, 2.5 ％), small cell carcinoma (three cases, 2.5 ％), basaloid squamous cell, adenosquamous, neuroendocrine carcinomas and carcinosarcoma (one case in each type, 0.8％).Conclusions Esophageal carcinoma was mostly located in the middle segment of in which squamous cell carcinoma was predominant while adenocarcinoma was less common.Esophageal cancer located at lower segment of esophagus is with a wide range of pathological spectrum, squamous cell carcinoma was still dominant, however, esophageal adenocarcinoma is rare.

A study of the clinico-histopathological features of erythematous tender nodules predominantly involving the extremities.

Background: Erythematous tender nodules predominantly involving extremities are frequently encountered in dermatology and rheumatology practice. They are diagnosed based on distinct clinical and histopathological features. However, in clinical situations, considerable overlap is observed that poses a diagnostic challenge. We undertook a study on clinico-histological patterns of inflammatory nodules over extremities. Methods: After detailed history and examination, a preliminary clinical diagnosis was made in 43 cases, followed by skin biopsy from representative nodules. Histological diagnosis made was correlated with clinical features. Results: Of 43 cases, a single clinical diagnosis was made in 25 (58.5%) cases while in the remaining cases more than one diagnosis was considered. On correlating with the histopathological diagnosis, concordance was observed in 51% cases while the remaining showed either histological discordance with clinical diagnosis (14% cases) or were kept in the undecided category (35% cases). Conclusion: Considerable clinico-histological overlap was observed in inflammatory nodules over extremities. Histopathology alone was not helpful in differentiating one entity from another at all times since variable histo-pathological patterns were seen.

Prueba del aliento y hallazgos histopatológicos asociados a la infección por Helicobacter pylori / Urea breath test and histopathological features related to helicobacter pylori infection

Existen múltiples métodos para diagnosticar la infección por H. pylori. Se plantea correlacionar la prueba del aliento con los hallazgos histopatológicos en el antro asociados a la infección por H. pylori en la población de Mucuchíes. Se incluyeron 108 pacientes entre 18 y 75 años. Se realizó prueba del aliento con 14C y endoscopia digestiva superior con obtención de cuatro muestras de mucosa antral. Se determinaron la sensibilidad, especificidad, valor predictivo positivo (VPP) y negativo (VPN), y la concordancia con la biopsia, además de correlaciones entre los valores de la prueba con la histopatología. Se obtuvieron 74 pacientes copositivos, con una sensibilidad del 87,05%, y una especificidad del 73,91% para la prueba del aliento. El VPP fue del 92,5%, y el VPN fue de 60,71%. El Kappa fue de 0,56. Se encontró correlación lineal entre la prueba del aliento, la densidad y la histología. La prueba del aliento constituye una herramienta útil en el diagnóstico de la infección por H. pylori y sus manifestaciones histopatológicas asociadas

There are many methods to diagnose H. pylori infection. It is proposed to compare the cuantitative14C Urea Breath Test with the histopathological features in the antrum related to H. pylori in the population of Mucuchíes. 108 patients between 18 and 75 years were included to perform the 14C Urea Breath Test, and the upper digestive endoscopy with four biopsy samples obtained from the gastric antrum. The sensitivity, specificity, PPV, NPV and Kappa index were determined for the 14C Urea Breath Test, and correlations between the 14C Urea Breath Test and histological features were determined too. We obtained 74 copositive patients, with a sensitivity of 87,05% and specificity of 73,91% for the 14C UBT. The PPV was of 92,5% and the NPV was of 60,71%. The Kappa index was of 0,56. A linear correlation between the test and the histological features was found. The 14C UBT is a very useful tool in the diagnosis of H. pylori infection and its related histopathological features

Fulminant hepatic failure in an infant with severe dengue infection.

Fulminant hepatic failure due to dengue infection is rare, although mild liver dysfunction is common. Here we report a fatal case of fulminant hepatitis in an infant infected with dengue 3 serotype. Attention must be given to the use of hepatotoxic drugs in some cases of dengue especially in infants.

Histopathologic Features of Papillary Cancer in the Breast

BACKGROUND: A papillary carcinoma in the breast is a rare carninoma with a predominantly papillary growth patttern. Its incidence is said to be 1% to 2% of all breast carcinomas in women. Because of its rarity, little is known about its histopathological features. This study was undertake to analyze the histopathological characteristics of papillary breast cancer. METHODS: During the 17 years from January 1980 through December 1996, among 2166 primary breast cancer patients, 26 patients, who had been diagnosed with papillary breast cancer pathologically at the Department of Surgery, Seoul National University Hospital, were elegible for this study. The histopathological characteristics of the tumors in these patients, including immunohistochemically stained tumor marker-e.g., bcl2, c-erbB2, cathepsin D, and p53-were compared to those of patients with an invasive ductal carcinoma, NOS (IDC). RESULTS: The mean age of the patients was 47 years old, ranging from 28 to 74 years. There was no statistically significant difference in the primary tumor size between the papillary cancer and the IDC (2.62 cm vs 3.33 cm, p=0.127). Twenty-four of the papillary cancer patients had no metastatic axillary node, and metastatic nodes were present in the papillary cancer than in the IDC, with statistical significance (0.27+/-0.19 vs 3.43+/-0.08, p=0.023). Papillary cancer seemed to have more frequent ER and PgR (60%, 77.8%) than IDC (44.1%, 56.1%), but there was no significance to these results (p=0.351, 0.309). In terms of tumor markers, the positivity of bcl2, c-erbB2, cathepsin D, and p53 in papillary cancer were 42.9%, 100%, 85.5%, and 66.7%, respectively. Of all significance, immunohistochemically determined tumor markers, c-erbB2 expression was observed with statistical significance, more frequently in papillary cancer (100% vs 68.5%, p=0.044). Patients with papillary cancer had an overall 10-year survival rate of 83.3%. CONCLUSION:Papillary breast cancer had fewer metastatic axillary node, but with little statistical significance for a more favorable outcome. The relation between c-erbB2 expression and papillary cancer seems to be interesting and needs to be further elucidated.
