PURPOSEWe aimed to explore the feasibility and clinical effectiveness of percutaneous CT-guided iodine-125 (125I) brachytherapy combined with chemotherapy for the treatment of patients with unresectable or locally advanced pancreatic carcinoma (PC).METHODSWe retrospectively reviewed 66 patients with Stage III and IV PC who had received chemotherapy. A total of 35 (53%) patients receiving 125I brachytherapy and chemotherapy (gemcitabine + cisplatin, GP) were classified as Group A, and 31 (47%) patients who received GP chemotherapy alone were categorized as Group B. The evaluated indications were local control rate (LCR), local progression-free survival (LPFS), overall survival (OS), treatment-related complications, and the degree of symptom relief. Kaplan-Meier curves, log-rank test and Cox regression models were generated and used for further analysis to identify predictors of outcomes.RESULTSThe median follow-up time was 6.00±0.84 months. The 1-, 3-, 6-, 12- and 18-month LCRs for Group A were 100% (35/35), 89.3% (25/28), 71.4% (15/21), 37.5% (3/8) and 33.3% (1/3), respectively; and those for Group B were 87.1% (27/31), 69.6% (16/23), 41.2% (7/17), 14.3% (1/7) and 0% (0/3), respectively. The LCR differed at 1-, 3- and 6-months (p = 0.032; p = 0.009; p = 0.030; respectively). The median LPFS was 7.00±0.30 months and 5.00±0.75 months for Groups A and B (p = 0.023), respectively; however, the median OS of the groups were not significantly different (8.00±0.77 months vs. 6.00±1.04 months. p = 0.917). No life-threatening complications occurred during or after the procedures. Patients in Group A experienced better pain control and relief of abdominal distension than those in Group B.CONCLUSIONCT-guided 125I brachytherapy is a feasible, safe, and valuable treatment for patients with unresectable PC.Pancreatic carcinoma (PC) is the fourth most common cause of cancer-related death in both males and females (1). Abdominal pain, distension and fatigue are relevant symptoms. However, these symptoms usually occur with advanced disease due to the deep located anatomy of the pancreas, making tumors difficult to detect (2). Tumors are inclined to invade vessels, nerves and lymphatic system, explaining its characteristics of being peripancreatic and extrapancreatic. Once these situation occur, unresectable disease is diagnosed based on certain criteria (3).For unresectable PC (UPC), some patients may refuse or give up their treatments because of its late stage when diagnosed, and poor general condition. An improvement of local control is an important part of disease management. The current treatment is multimodality therapy, including chemotherapy, irreversible electroporation, radiotherapy, and supportive care. However, the prognosis is poor, with a 1-year survival rate of 20% and a 5-year survival rate of less than 5% (4, 5). The first-line therapy for UPC with or without metastasis is chemotherapy, including gemcitabine with cisplatin or paclitaxel, FOLFIRINOX or FOLFOX. Despite advancements in chemotherapy, many patients are not able to tolerate treatment, mainly due to their poor mental and physical health at the time of diagnosis and the severe toxicities, including myelosuppression and vomiting. Irreversible electroporation, a local destructive therapy, is based on the transmission of high-voltage current pulses direct through the tumor tissue, leading to alteration of irreversible permeation in the integrity of cell membrane and cell death (6). Nevertheless, this procedure is often implemented under laparotomy and the expense is high. New technologies in external beam radiotherapy have also been developed, such as stereotactic body radiotherapy and cyberknife. However, PC is relatively insensitive to external radiation. Also, the higher the dose received, the higher the risk of severe adverse effects, especially to cardinal organs such as the intestine and liver. Thus, the dose has to be controlled and rapidly reduced, ultimately increasing the risk of residual tumor and treatment failure.Iodine-125 (125I) brachytherapy, a treatment as internal radiotherapy, has been considered a useful and minimally invasive modality. It has been shown to be a safe and effective option for many types of tumors such as those on brain, thoracic, prostate and soft tissue (7–10), and remarkable advantage of few complications and side effects (11, 12). Under the real-time imaging guidance (CT or ultrasound), the 125I seed-specific needle is used to insert the seed into the tumor tissue. When the needle reaches the target area according to the preoperative plan, the 125I seed is released by a single use of implantation gun after pulling out the needle core. Each seed is implanted one by one within the tumor by drawing back the needle along the needle track. The 125I seed continuously emits X-rays and γ-rays within the target area, with a half-life of 59.6 days and a radiation diameter of 1.7 cm. The miniature seed has higher local radiation energy than conventional radiotherapy, while decreasing rapidly with increasing distance from the target area. CT is characterized by clear images, real-time observations, thin slices, and good tissue contrast on enhancement scanning. These characteristics make it possible for CT-guided 125I brachytherapy to safely and visibly cover the target lesion completely, avoiding injury to the adjacent tissues. However, there have been few reports about CT-guided 125I brachytherapy combined with chemotherapy for this disease. The aim of our study was to evaluate and determine the effectiveness and feasibility of this combination treatment for UPC. 相似文献
