February 2025

Division of Psycho-Oncology (A.O.), Exploratory Oncology Research and Clinical Trial Center, National Cancer Center, Kashiwa, Japan.

Article Synopsis
  • Patients in Japan often aren't informed about their cancer diagnoses due to cultural norms prioritizing family-oriented autonomy, which may negatively impact their quality of death (QOD) and quality of care (QOC).
  • This study analyzed responses from bereaved family members to compare QOC and QOD between cancer patients who were informed of their diagnosis versus those who were not.
  • Results showed that those who received a cancer diagnosis had significantly better QOC and QOD, and their families reported higher satisfaction with overall care.

Occipital lobectomy is a widely accepted procedure for treatment of occipital gliomas and occipital lobe epilepsy, but its technical nuances are not well discussed. Anatomically, the occipital lobe, also known as the cuneus or visual area, is an isolated region in terms of vascular supply. The terminal branches of posterior cerebral arteries, including parieto-occipital and calcarine arteries, are the major vessels supplying this region.

Chemotherapy has been developed for many years for malignancies, including advanced pancreatic cancer, downsizing the primary site, thereby enabling complete cure with the combination of conversion surgery. Pathological complete remission from operation samples was usually identified as a promising indication for a good prognosis for many carcinomas. Several case reports consisting of pathological complete remission after chemotherapy application have been reported but no case of pathological complete remission that resulted from successful extensive resection by surgery after S-1, irinotecan, and oxaliplatin (SIROX) chemotherapy.
