Clinical Case

êsRm multiparametric prostate in an apparatus 1.5 screen with XL coil 16-channel torso without the use of rectal coil for evaluation and investigation of prostate lesions in high resolution.

A 70-year-old patient presented changes in the PSA rate arriving at our service with indication of a multiparametric study of the prostate without previous biopsy, for anatomical and functional evaluation of the prostate and screening for possible lesions.

High resolution T1 and T2 images were performed on the 3 planes and heavy functional images in diffusion and study of prostate perfusion.

Results: prostate measuring 4.2 × 3.7 × 4.3 cm, with an estimated volume of 43 cm cubic, with internal gland heterogeneity without nodule configuration, nodule with low T2 sign, showing diffusion restriction And low signal on the ADC map, in addition to the increase in T1-weighted perfusion, measuring 1.5 × 1.1 cm, located in the lateral portion of the peripheral zone of the right third of the right third.

Diagnostic impression: High suspicion test for clinically significant malignant neoplasm classified as (PIRADS IV).

We conclude that 1.5 T MRI without the use of a rectal coil can evaluate prostate lesions with the protocol and appropriate high resolution techniques without causing patient discomfort and with a highly accurate diagnostic pattern.

Does anyone disagree with the images and the result?

Additional Cases

Is local or major surgery better for treating early rectal cancer with or without additional treatments before or after surgery?
Key messages
We are uncertain if local excision (LE) (removal through the anus of an early rectal cancer that has not grown beyond the muscle layer of the rectum, or stage I) may shorten the period of being cancer‐free after surgery compared to radical resection (RR) (removing the entire rectum and its surrounding tissues through a major surgery). It is also unclear if LE affects cancer‐related survival related compared with RR.

There is probably a large reduction in minor complications after surgery (only necessitating medications or supportive measures) with LE compared with RR for the treatment of early rectal cancer. It is unclear if LE lowers the rate of major complications.

Based on only one study, LE results in better quality of life and anal sphincter function.

How is early rectal cancer treated?
The currently recommended treatment for stage I rectal cancer is a major surgery for removal of the rectum with all its surrounding supporting tissues, known as radical resection (RR). This extensive surgery carries significant risks of surgical and functional complications. Recently, an alternative treatment using advanced instruments through the anus has been popularized. This has enabled precise removal, or local excision (LE), of only the tumor safely through the anus with fewer complications and faster recovery. Sometimes additional therapies such as chemotherapy or radiotherapy may be used in conjunction before or after the surgery.

What did we find?
We found four studies that involved 266 participants with early rectal cancer with a median age of 60 years undergoing RR or LE. Participants were studied from 17.5 months in the shortest study to up to 9.6 years in the longest study.

What are the limitations of the evidence?
We have low confidence in the evidence mainly because it was based only on a few studies, and due to the way the studies were conducted. In addition, it is possible that the results of the studies could have been affected by the fact that participants and investigators were aware of which treatment participants had received.
