Postoperative adjuvant chemotherapy in patients with gastric cancer based on the Nationwide Gastric Cancer Registry in Japan.

The nationwide registry of the Japanese Gastric Cancer Association contains data related to the efficacy of adjuvant chemotherapy and prognostic factors across this patient population; elderly patients with advanced resectable gastric cancer are especially prevalent. Here, we analyzed data from 34,931 patients, who were treated between 2011 and 2013 at 421 hospitals in Japan. Although adjuvant chemotherapy was effective overall, 75 years or older elderly patients had a worse prognosis compared to younger patients.

Development of an AI-based support system for controlled ovarian stimulation.

Purpose: Controlled ovarian stimulation (COS) is vital for IVF. We have developed an AI system to support the implementation of COS protocols in our clinical group.

Methods: We developed two models as AI algorithms of the AI system.

[Development of Deep Convolutional Neural Network-Based Algorithm for Muscle Biopsy Diagnosis].

To diagnose muscle disease, histopathologic evaluation of muscle biopsy is essential. In addition, since myositis has a well-established treatment, an accurate diagnosis is required. However, distinguishing myositis from other muscle diseases is challenging for pathologists.

Deep convolutional neural network-based algorithm for muscle biopsy diagnosis.

Histopathologic evaluation of muscle biopsy samples is essential for classifying and diagnosing muscle diseases. However, the numbers of experienced specialists and pathologists are limited. Although new technologies such as artificial intelligence are expected to improve medical reach, their use with rare diseases, such as muscle diseases, is challenging because of the limited availability of training datasets.

Deep learning shows the capability of high-level computer-aided diagnosis in malignant lymphoma.

A pathological evaluation is one of the most important methods for the diagnosis of malignant lymphoma. A standardized diagnosis is occasionally difficult to achieve even by experienced hematopathologists. Therefore, established procedures including a computer-aided diagnosis are desired.
