For the regeneration of injured peripheral nerves, we have devised a PGA-tube that is composed of a tube of polyglycolic acid containing collagen sponge. This PGA-tube was applied clinically to reconstruct a peripheral nerve that had been resected during extended surgical resection of for intrapelvic recurrent rectal cancer. Four months after the surgical resection, the function of the left hip joint has improved remarkably, whereas the function had been lost just after the operation. It is suggested that the PGA-tube will be useful for regeneration of peripheral nerves that are resected during operation for intrapelvic malignancy.

Background: We evaluated the prognostic effect of lymphocytopenia caused by preoperative radiation therapy and chemotherapy in patients with rectal cancer.
Methods: A total of 147 patients with rectal cancer who underwent preoperative chemoradiotherapy and surgical resection between 2008 to 2021 participated. Lymphocyte nadir less than 500/μl were defined as lymphocytopenia in this study.

Article Synopsis
- Primary synovial sarcoma in the pelvis is a very rare and aggressive cancer, often diagnosed at an advanced stage, hindering effective treatment options due to a lack of established guidelines.
- A case study of a 32-year-old male revealed a large pelvic mass leading to surgery, where he was diagnosed with biphasic synovial sarcoma; despite receiving various therapies, the cancer returned and led to his death after 28 months.
- Early detection using imaging techniques like MRI and CT scans is crucial for improving treatment outcomes, emphasizing the need for increased awareness and better management strategies for this uncommon malignancy.

Calyceal rupture, defined as the extravasation of urine from the renal calyces into the perinephric or paranephric spaces, typically results from increased intrapelvic pressure due to urinary tract obstruction. This condition can lead to the formation of a perinephric urinoma and severe complications, such as infection, abscess formation, and impaired renal function. Timely diagnosis and management are crucial to prevent these adverse outcomes.

Purpose: For the treatment of locally advanced rectal cancer (LARC), research on primary lesions with mesorectal fascia (MRF) involvement is lacking. This study analyzed the clinical outcomes and efficacy of dose-escalated neoadjuvant concurrent chemoradiotherapy (NCRT) to patients with LARC involving MRF.
Materials And Methods: We retrospectively reviewed 301 patients who were diagnosed with LARC involving MRF and underwent NCRT followed by total mesorectal excision (TME).
