RESUMO
PURPOSE: To compare the safety and efficacy of CPG in the rectus abdominis and intercostal regions. MATERIALS AND METHODS: This retrospective study included 226 patients who underwent CPG at a single center, with the stoma placed in the rectus abdominis or intercostal region. Surgical outcomes and complications, such as pain and infection within 6 months postoperatively, were recorded. RESULTS: The surgical success rate was 100%, and the all-cause mortality rate within 1 month was 0%. An intercostal stoma was placed in 56 patients; a rectus abdominis stoma was placed in 170 patients. The duration of surgery was longer for intercostal stoma placement (37.66 ± 14.63 min) than for rectus abdominis stoma placement (30.26 ± 12.40 min) (P = 0.000). At 1 month postsurgery, the rate of stoma infection was greater in the intercostal group (32.1%) than in the rectus abdominis group (20.6%), but the difference was not significant (P = 0.077). No significant difference was observed in the infection rate between the two groups at 3 or 6 months postsurgery (P > 0.05). Intercostal stoma patients reported higher pain scores during the perioperative period and at 1 month postsurgery (P = 0.000), but pain scores were similar between the two groups at 3 and 6 months postsurgery. The perioperative complication rates for intercostal and rectus abdominis surgery were 1.8% and 5.3%, respectively (P = 0.464), with no significant difference in the incidence of tube dislodgement (P = 0.514). Patient weight improved significantly at 3 and 6 months postoperatively compared to preoperatively (P < 0.05). CONCLUSION: Rectus abdominis and intercostal stomas have similar safety and efficacy. However, intercostal stomas may result in greater short-term patient discomfort.

PURPOSE: To investigate the safety and efficacy of iodine-125 seed implantation in the treatment of abdomen-thorax desmoid tumors (DTs). METHODS AND MATERIALS: Data from 14 DT patients who received brachytherapy with iodine-125 seeds were retrospectively collected from 2014 to 2020. The operation was completed using CT guidance and the treatment plan system (TPS). The number of lesions and the target dosimetry parameters were recorded. After brachytherapy, the lesions were evaluated using response evaluation criteria in solid tumors (RECIST). RESULTS: Fourteen patients with 18 lesions were enrolled in this study; eleven lesions were in the thorax, seven were in the abdomen, and the lesion gross tumor volume (GTV) was 82.10 cc (interquartile range [IQR]: 40.37, 203.42 cc). The median number of seeds was 88 (IQR: 35, 158), and the median prescription dose was 120 Gy (IQR: 115, 120 Gy). The D90 was 123 ± 16.7 Gy, the V90 was 97% (IQR: 95.00, 97.25%), and the V200 was 27% (IQR: 14.50, 33.00%). The median follow-up time for each lesion was 34 (IQR: 23, 67) months, and the local response rate was 100%. Following brachytherapy, the overall survival was 52.3 ± 30.72 months. One year after brachytherapy, one patient experienced persistent worsening of a brachial plexus injury; another received a ureteral stent. No brachytherapy-related complications were observed in the remaining patients. CONCLUSIONS: Iodine-125 brachytherapy is a novel treatment option for DT of the abdomen and thorax. Although it is a safe and effective treatment, the radiation dose of iodine-125 brachytherapy for DT-embedded organs at risk must be investigated further.

Objective: Aggressive angiomyxoma (AAM) is a rare, locally aggressive soft tissue neoplasm with a marked tendency for local recurrence after surgery. Although hormone therapy, radiation therapy, and vascular embolization can be performed, we investigated the safety and efficacy of a new chemical ablation protocol for AAM. Methods: This study included two female AAM patients from 2012 to 2016. The patients' clinical and imaging data were collected. The amount of anhydrous ethanol and glacial acetic acid used for chemical ablation was documented, and the management of any complications was detailed. Results: The maximum dimensions of the residual tumor were 12.6 cm and 14.0 cm. In one case, the lesion was in the pelvis and protruded into the vulva. Eighty milliliters of liquid with a mixture of glacial acetic acid, anhydrous ethanol, and iohexol (10:9:1) was used for chemical ablation therapy via multipoint injections with a single needle. However, a pelvic fistula developed 1 month later. In another case, the lesion was located in the abdominal wall. The ablation procedure was improved by performing chemical ablation therapy with multiple needles for multi-point injections of smaller than 30 ml injections for each procedure. To date, no recurrence or metastasis has been observed in the two cases. Conclusion: The preferred treatment for AAM is complete resection. Chemical ablation therapy is a novel adjuvant therapy for AMM. Nonetheless, more research is needed to confirm these findings.
