Conjugated fatty acids (CFAs) have been known for their anti-tumor activity. However, the mechanism of action remains unclear. Here, we identify CFAs as inducers of glutathione peroxidase 4 (GPX4) degradation through chaperone-mediated autophagy (CMA).

As prostate cancer (PCa) is particularly reliant on fatty acid metabolism, we explored the contribution of peroxisomal β-oxidation (perFAO) to PCa viability and therapy response.
Methods: Bioinformatic analysis was performed on clinical transcriptomic datasets to identify the perFAO enzyme, 2,4-dienoyl CoA reductase 2 (DECR2) as a target gene of interest.

The method of image processing has increased along with the workstation in recent years and developments in the software of each modality. Maximum intensity projection (MIP) and volume rendering (VR) are among the general processing methods used. However, MIP and VR have their respective limitations.

Methods: The major inclusion criteria were primary superficial bladder tumour (Ta, T1, G1, G2) and new cases of primary multiple tumours, or recurrent cases. The major exclusion criteria were Tis or G3 tumours.
A total of 465 patients with primary and multiple or recurrent, stages Ta and T1 superficial bladder cancer were included in this randomized multicenter trial to compare the prophylactic effect by 17 times instillation of 40 mg doxorubicin or 40 mg epirubicin with no instillation after transurethral resection of tumor(s). The primary endpoint was first recurrence after transurethral resection. Endoscopic examination as well as urinary cytology was performed in each case every three months.

In the third trial, reported herein, patients with recurrent bladder cancer or multiple primary cancer were selected and randomized to one of four groups using the envelope method after complete resection of the original tumors. Group A was given Adriamycin alone, group B received oral 5-fluorouracil (5-FU), group C was given Adriamycin and oral 5-FU, and group D served as the control group.

The "Response criteria of Japan Society for Cancer Therapy" were followed for the handling of subjects and the evaluation of antitumor effect. MHR-24 was administered at a daily dosage of 5,000-10,000 JRU by intravenous drip and MOR-22 at a dosage of 5,000,000 IU daily was administered intramuscularly at the same time.

This is the first controlled multicenter study for governmental approval of BCG Tokyo 172 strain for the treatment of superficial bladder cancer and CIS of the bladder. One hundred-fifty-seven patients (125 with Ta or T1, and 32 with CIS) were treated by 80 mg of BCG diluted in 40 ml of saline, once a week for 8 weeks.

Evaluation of the clinical responses obtained in 86 evaluable patients revealed 13 complete responses, 29 partial responses, 4 minor responses, 19 cases of no change, and 21 cases of progressive disease. The overall response rate was 48.

A total of 443 patients (number of evaluable patients, 284) were registered from July 1987 to December 1989 and randomised into 3 groups. Group A received 21 intravesical instillations of Adriamycin (ADM) at 20 mg/40 ml physiological saline for 2 years after undergoing transurethral resection (TUR); group B was given the same dose as group A but received 6 intravesical instillations for 2 weeks before undergoing TUR; and group C served as a control and underwent TUR only.

In order to examine its clinical efficacy, recombinant human interferon-beta (rIFN-beta) was instilled intravesically into 51 patients with superficial bladder cancer. Ten patients, who received intermittent intravesical instillation at a dose of (3-36) x 10(6) U rIFN-beta on days 1-3 every week, showed no response. Thirty-two patients received intravesical instillation at a dose of (3-36) x 10(6) U every day for 10-20 days.

A comparative investigation was conducted on (2''R)-4'-O-tetrahydropyranyl-doxorubicin (Adriamycin) (THP) and Adriamycin (ADM) from the above viewpoint using cultured MBT-2 and T-24 cell lines. From in vitro experimental systems, it is surmized that THP is taken up by bladder tumor cells more rapidly than ADM is, and that THP is thus able to exert its effect on the bladder tumor within a shorter time than that required by ADM.
