A 53-year-old woman was diagnosed with gastrointestinal stromal tumor (GIST) of the stomach. Computed tomography (CT) revealed a huge mass (12 cm in diameter), likely to invade pancreas and spleen. In the operation field, the tumor was in an unresectable state. The patient was then started on imatinib therapy for 4 months. On follow-up imaging studies, the tumor almost disappeared. We performed total gastrectomy and splenectomy upon which two small-sized residual tumors were found on microscopy. In this paper, we describe a case of clinicopathologic change in unresectable GIST after neoadjuvant imatinib mesylate.

Association Between Baseline and Changes in Early Neutrophil-to-Lymphocyte Ratio on Survival in Patients with Metastatic Bladder Carcinoma Treated with Immunotherapy.

: A high baseline neutrophil-to-lymphocyte ratio (NLR) is a poor prognostic factor in various cancers. However, its predictive role in metastatic bladder cancer (mBC) treated with immunotherapy is unclear. In this study, we aimed to investigate the relationship between the baseline and change in NLR and overall survival in mBC patients treated with immunotherapy, with the potential to significantly impact patient care.

Background: Breast cancer (BC) has exhibited varied epidemiological trends based on distinct age categories. This research aimed to explore the incidence and mortality rates of BC within pre-defined age groups in the Brazilian population.
Methods: BC incidence trends were assessed from 2010 to 2015 using Brazilian Population-Based Cancer Registries, employing age-standardized ratios and annual average percentage change (AAPC).

Background: Pancreatic adenocarcinoma (PAAD) is a common malignancy with a very low survival rate. More and more studies have shown that SPTAN1 may be involved in the development and progression of a variety of tumors, including rectal cancer, Pancreatic adenocarcinoma, etc., and may affect their prognosis.

To analyze the morphologic changes and the extent of severity in end-stage heart disease; and to explore the correlation with their clinical features. Twelve cases of recipients who underwent pediatric cardiac allograft transplantation were collected from May 2022 to November 2023 at the Seventh Medical Center of People's Liberation Army of China General Hospital. Gross pathologic examinations were performed and morphological changes were observed under a light microscope after HE, Masson's trichrome, and reticulin staining.

Article Synopsis
- National guidelines recommend segmental colectomy for appendiceal neuroendocrine neoplasms larger than 2.0 cm due to risks of lymph node involvement, with conditional overall survival becoming an important prognostic tool.
- A study of 3,541 patients revealed that 16% had positive lymph nodes, and factors like size, depth of invasion, and lymphovascular involvement were correlated with metastasis.
- The findings suggest that more clinicopathologic factors should influence decisions on surgical treatment and surveillance for better survival rates, especially for patients with more aggressive histologies.
