Background/aim: The aim of this study was to evaluate hepatectomy cases that underwent preoperative chemotherapy to examine the relationship between the development of desmoplastic histopathological growth pattern (dHGP) and prognosis and recurrence and determine whether it is useful for evaluating preoperative chemotherapy.
Patients And Methods: A total of 133 cases with hepatic metastasis for colorectal cancer that underwent surgical resection.
Results: Of the 102 cases that underwent preoperative chemotherapy, 34 (33%) were determined to be dHGP positive, which was statistically significantly higher than the 2 of 31 cases (6.5%) that had not undergone preoperative chemotherapy. Regarding the 5-year recurrence-free survival, the dHGP group had a value of 50.3%, whereas the non-dHGP group had a value of 7.1%. For the 5-year overall survival, the dHGP group had a better prognosis than the non-dHGP group (57.6% vs. 37.1%, respectively), with a statistically significant difference. Univariate analysis of recurrence-free survival showed that the number of tumours, the Response Evaluation Criteria in Solid Tumors, and the presence or absence of dHGP were prognostic factors, whereas multivariate analysis showed that the presence or absence of dHGP was an independent prognostic factor. Univariate analysis of the overall survival showed that the number of tumours, the Response Evaluation Criteria in Solid Tumors, and presence or absence of dHGP were prognostic factors. Multivariate analysis showed that the presence or absence of dHGP was an independent prognostic factor.
Conclusion: dHGP is useful as a new evaluation method for evaluating the efficacy of preoperative chemotherapy.

Background: The FOxTROT trial has reported advantages of neoadjuvant chemotherapy (NAC) in locally advanced colon cancer (LACC). Here we present results of the embedded randomized phase II trial testing the addition of panitumumab to neoadjuvant FOLFOX compared with FOLFOX alone in RAS and BRAF-wild-type patients and with biomarker hyperselction.
Patients And Methods: Patients had operable, CT-predicted stage T3-4, N0-2, M0 colon adenocarcinoma.

Background: The purpose of the present study was to evaluate clinicopathological characteristics, patterns of recurrence, survival outcomes, and implications for the addition of chemoradiotherapy for patients with resected perihilar and intrahepatic cholangiocarcinoma (CCA).
Materials And Methods: For the present retrospective study, we identified 38 and 10 patients with resected perihilar and intrahepatic CCA. In perihilar CCA, adjuvant treatment was given as chemotherapy ( = 13) or chemoradiotherapy ( = 10).

Phaeohyphomycotic agents causing central nervous system (CNS) infection is rare and is known to affect immunocompetent individuals. We present a patient with a CNS phaeohyphomycotic abscess that had developed within a temporal lobe glioma. Magnetic resonance imaging (MRI) performed two months prior to the surgery showed only the presence of a neoplasm.

Karnofsky Performance Status (KPS) is a widely used scale to assess performance status. KPS ≥ 50% implies that patients can live at home. Therefore, maintaining KPS ≥ 50% is important to improve the quality of life of patients with glioblastoma, whose median survival is less than 2 years.
