In robot-assisted surgery, in which haptics should be absent, surgeons experience haptics-like sensations as "pseudo-haptic feedback". As surgeons who routinely perform robot-assisted laparoscopic surgery, we wondered if we could make these "pseudo-haptics" explicit to surgeons. Therefore, we created a simulation model that estimates manipulation forces using only visual images in surgery.

Article Synopsis
  • Bone metastatic renal cell carcinoma (RCC) cells alter bone marrow vasculature by releasing extracellular vesicles (EVs), which play a significant role in intercellular communication affecting angiogenesis.
  • The study established a bone metastatic RCC cell line and injected their EVs into immunodeficient mice, observing changes that indicated increased angiogenesis and enhanced capillary function.
  • Proteomic analysis revealed that the protein aminopeptidase N (APN) found in the EVs promotes angiogenesis; the depletion of APN reduced this effect, suggesting its potential role in bone metastasis development.

Objective: This study investigated the efficacy of docetaxel (DOC) and cabazitaxel (CBZ) and examined the factors associated with the prognosis of patients with castration-resistant prostate cancer (CRPC) receiving DOC-CBZ sequential treatment in Japanese real-world data.

Methods: We retrospectively evaluated data for 146 patients who received DOC followed by CBZ. The correlations of prostate specific antigen (PSA) decrease rate and time to progression between DOC and CBZ treatment were examined.

Testicular epidermoid cysts are relatively rare, accounting for about 1% of all testicular tumors, and are often treated by high orchiectomy. We describe here the case of a testicular epidermoid cyst treated by testicle-sparing surgery due to a preoperative diagnosis. A 23-year-old man complained of a painless mass in the right scrotum.

A 47-year-old man was referred to our hospital for epigastric pain and cough, and was given a diagnosis of left clear cell renal carcnoma with multiple pulmonary metastases based on the results of renal tumor biopsy (cT3aN0M1). He received nivolumab/ipilimumab combination therapy, but developed diarrhea (grade 3) on day71, and treatment was discontinued. However, a deep and durable response after discontinuation of treatment was shown, and we were able to perform nephrectomy on day336.
