Purpose: This study aimed to evaluate the incidence and factors associated with long-term functional outcomes of sacrococcygeal teratoma (SCT) after resection in neonates and infants., Methods: Twenty-nine patients with a minimum of 3 years of follow-up who underwent resection and were histologically diagnosed with SCTs between 1982 and 2017 at our institution were included., Results: The median age at the time of the study was 10.0 years. Functional disorders occurred after surgery in 6 (20.7%) patients. Anorectal dysfunction, urologic dysfunction, and lower-extremity motor disorders occurred in 6 (20.7%), 4 (13.8%), and 3 (10.3%) patients, respectively. One patient with all three types of functional disorders developed intestinal perforation due to ileus and died of sepsis at 13 years of age. The overall mortality rate after tumor resection was 3.4%. The patients who developed functional disorders presented a low 1-min Apgar score, larger tumors requiring abdominosacral resection, surgical injury to the pelvic organs, and immature or malignant histological findings., Conclusion: Although the mortality rate was low, the long-term rate of functional disorders after SCT resection was approximately 20%. SCT patients with large tumors, surgical injury to the pelvic organs, and immature or malignant histological findings require thorough follow-up.

Background: Soft tissue sarcomas (STS) of pelvic origin in boys often involve the urogenital organs. The optimal extensiveness of radical surgery has long been an issue of discussion, since exenterative surgeries result in severe urogenital adverse effects. We conducted a retrospective review of patients with pelvic STS treated in two regional center hospitals and assessed the radicality of surgery and the functional outcome of the bladder., Patients: Medical records and surgical reports of nine cases (embryonal rhabdomyosarcoma 6, malignant triton tumor 2, suspected rhabdomyosarcoma 1) treated within 1997-2012 were reviewed. Site of origin was prostate in seven, retroperitoneal in two. Average follow-up period was 96 months., Treatment and Outcome: All cases were subjected to neoadjuvant chemotherapy. Response was PR in four, SD in two, and PD in two. Radical surgery resulted in gross total resection in eight, and partial resection in one. Three underwent cystoprostatectomy, two cases underwent prostatectomy, and bladder-preserving tumor resection was carried out in four cases. At the last follow-up, three retained a functional bladder. Two required augmentation cystoplasty with intestinal conduits., Conclusions: The majority of the on-going clinical trials recommend conservative surgery for bladder/prostate rhabdomyosarcoma, and to preserve the bladder function particularly in chemosensitive tumors. Some other groups, however, advocate the importance of radical surgery to prevent local relapse. These reports include heterogenous group of patients in the cohort, and therefore it is difficult to draw a conclusion of which approach truly contributes to the survival of the patients better. Future studies should evaluate bladder and sexual function objectively to establish reliable evidence regarding the benefit and adverse effects of different surgical approaches. These data would be informative to optimize the treatment balance for children with pelvic rhabdomyosarcomas.

Radiotherapy is a cornerstone in the treatment of malignancies in the pelvis. Consequently, there is usually exposure of the intestine and especially the lower colon and rectum, with ensuing disturbances in bowel habits at different times following radiotherapy. The main problem is diarrhoea associated with lactose intolerance, bile salt absorption and fat malabsorption. Bacterial contamination has also been described. In the present study we have evaluated the influence of the active administration of specific bacterial cultures in fermented milk, which inhibit the growth of potentially pathogenic micro-organisms, to 40 consecutive patients with chronic alteration in their bowel habits caused by previous radiotherapy of pelvic malignancies. The results suggest that intake of fermented milk products could be of value in decreasing chronic bowel discomfort following radiotherapy of pelvic malignancies. However, a more extensive study is warranted in order to very the significance of the results and to find the optimal product.
