BACKGROUND & OBJECTIVE Peripheral tumor growth pattern plays an important role in the local recurrence and metastases of soft tissue sarcoma. This study was to determine the peripheral growth pattern of soft tissue sarcoma by magnetic resonance imaging (MRI), explore its correlation to histological grade, and assess biological features of soft tissue sarcoma before operation. METHODS MRI was ...

Defining distinctive histologic characteristics of ROS1-rearranged non-small-cell lung carcinomas (NSCLCs) may help identify cases that merit molecular testing. However, the majority of previous reports have focused on surgical specimens but only limited studies assessed histomorphology of advanced NSCLCs. In order to identify the clinical and histological characteristics of ROS1-rearranged adv...

Background & objective: Regarding the importance of histologic examination of testicular biopsy for clinical planning of infertility, the current study was conducted to compare 2 separate histologic examination of testicular biopsy. Also, some cases with known fertility outcome were followed and their histological patterns were also compared with those of the outcome. ...

AIMS Papillary thyroid carcinoma (PTC) is classified into two subgroups-common type and other histological variants. Correlations between further subgrouping of the common type and patient prognosis are not well documented. AIMS To introduce two novel histological parameters to characterise PTC-loss of cellular polarity and loss of cellular cohesiveness. To investigate a new subgroup of commo...

This paper deals with the refractoriness of PET \ mouse integument to the subcutaneous administration of nerve growth factor. Newborn mice were injected once daily with NGF through ten injections. Gross and histological examination showed that the skin of the experimental animals was completely unresponsive to this agent. No alterations in the hair growth cycle or pattern were ·observed.

were the clinical variables affecting survival. The histological variables related to survival were; mitotic count, necrosis, nuclear pleomorphism, vascular and lymphatic permeation and an undifferentiated growth pattern. All these features could be detected with routine histological stains, whereas immunocytochemical methods for demonstrating neuron specific enolase were of no help in assessin...

Soft tissue sarcoma (STS) with an infiltrative histologic growth pattern, when compared to STS with an expansile pattern, may pose difficulties in local control. Preoperative assessment of the presence of infiltrative histologic growth pattern would be helpful in deciding treatment strategies. A review of 144 patients who underwent surgery for extremity STS was performed. Microscopically, the h...

BACKGROUND Patients with resectable colorectal lung oligometastasis (CLOM) demonstrate a heterogeneous oncological outcome. However, the parameters for predicting tumor aggressiveness have not yet been fully investigated in CLOM. This study was performed to determine the prognostic value of histological growth patterns in patients who underwent surgery for CLOM. METHODS The study included 92 ...
