Chemoradiotherapy Combined with Brachytherapy for the Definitive Treatment of Esophageal Carcinoma. Cancers (Basel) 2023; 15:3594. [PMID: 37509257 PMCID: PMC10377190 DOI: 10.3390/cancers15143594] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 06/22/2023] [Accepted: 07/10/2023] [Indexed: 07/30/2023] Open
Abstract
This study aims to investigate the effect of dose escalation with brachytherapy (BT) as an addition to definitive chemoradiotherapy (CRT) on local control and survival in esophageal cancer. From 2001 to 2020, 183 patients with locally limited or locally advanced esophageal cancer received definitive CRT with or without brachytherapy in a two-center study. External-beam radiotherapy was delivered at 50.4 Gy in 1.8 Gy daily fractions, followed by a sequential boost to the primary tumor of 9 Gy in 1.8 Gy daily fractions if indicated. Intraluminal high dose rate (HDR) Ir-192 brachytherapy was performed on 71 patients at 10 Gy in two fractions, with one fraction per week. The combined systemic therapy schedules used included 5-fluorouracil/cisplatin or 5-fluorouracil alone. Cisplatin was not administered in patients receiving brachytherapy. The median local progression-free survival was significantly extended in the BT group (18.7 vs. 6.0 months; p < 0.0001), and the median local control was also significantly prolonged (30.5 vs. 11.3 months, p = 0.008). Overall survival (OS) significantly increased in the BT group (median OS 22.7 vs. 9.1 months, p < 0.0001). No significant difference in the overall rate of acute toxicities was observed; however, the rate of acute esophagitis was significantly higher in the BT group (94.4% vs. 81.2%). Likewise, the overall rate of late toxicities (43.7% vs. 18.8%) was significantly higher in the BT group, including the rate of esophageal stenosis (22.5% vs. 9.8%). There was no difference in the occurrence of life-threatening or lethal late toxicities (grades 4 and 5). Brachytherapy, after chemoradiation with single-agent 5-FU, represents a safe and effective alternative for dose escalation in the definitive treatment of esophageal cancer.

Comparative study of concomitant chemoradiation versus concomitant chemoradiation followed by high-dose-rate intraluminal brachytherapy in locally advanced esophageal carcinoma: a single institutional study. J Contemp Brachytherapy 2018; 10:225-231.

Abstract
Purpose The aim of this study is to compare efficacy and toxicity between concurrent chemoradiotherapy (CCRT) followed by high-dose-rate intraluminal brachytherapy (ILBT) and CCRT in inoperable, locally advanced esophageal carcinoma. Material and methods Thirty-four patients with inoperable, locally advanced esophageal carcinoma were randomized into two arms. In the CCRT + ILBT arm (arm A), eighteen patients received 50.4 Gy at 1.8 Gy per fraction over 5.6 weeks, along with concurrent cisplatin (75 mg/m2) intravenously on day 1, and 5-fluorouracil (1000 mg/m2) continuous intravenous infusion on days 1-5, starting on the first day of irradiation and repeated after 28 days. This was followed by ILBT boost with a dose of 10 Gy in 2 fractions, one week apart. In the CCRT arm (arm B), sixteen patients received two cycles of chemotherapy, using the same schedule, along with external beam radiotherapy fractionated in a similar manner without brachytherapy boost. The endpoints were tumor response, acute and late toxicities, disease and progression-free survival. Results With a median follow-up of 13 months, the complete response rate was 88.89% in arm A and 87.50% in arm B (p = 0.71). Acute esophageal toxicity was higher in CCRT followed by ILBT arm (p = 0.60). There was no significant difference between the Kaplan Meier survival plots of disease-free survival (p = 0.68) and progression-free survival (p = 0.55). Conclusions In our study, addition of brachytherapy as a boost following concurrent chemoradiation failed to improve treatment outcomes without additional toxicity in locally advanced esophageal cancer.

Abstract
The treatment of locally advanced esophageal cancer is controversial. For patients who are candidates for surgical resection, multiple prospective clinical trials have demonstrated the advantages of neoadjuvant chemoradiation. For patients who are medically inoperable, definitive chemoradiation is an alternative approach with survival rates comparable to trimodality therapy. Although trials of dose escalation are ongoing, the standard radiation dose remains 50.4 Gy. Modern radiotherapy techniques such as image-guided radiation therapy with motion management and intensity-modulated radiation therapy are strongly encouraged with a planning objective to maximize conformity to the intended target volume while reducing dose delivered to uninvolved normal tissues.

[PMID: 26413250 PMCID: PMC4581367 DOI: 10.17795/ijcp2330] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/24/2014] [Revised: 11/16/2014] [Accepted: 12/14/2014] [Indexed: 11/25/2022]
Abstract
Background: The high-dose-rate (HDR) brachytherapy might be an effective tool for palliation of dysphagia. Because of some concerns about adverse effects due to absorbed radiation dose, it is important to estimate absorbed dose in risky organs during this treatment. Objectives: This study aimed to measure the absorbed dose in the parotid, thyroid, and submandibular gland, eye, trachea, spinal cord, and manubrium of sternum in brachytherapy in an anthropomorphic phantom. Materials and Methods: To measure radiation dose, eye, parotid, thyroid, and submandibular gland, spine, and sternum, an anthropomorphic phantom was considered with applicators to set thermoluminescence dosimeters (TLDs). A specific target volume of about 23 cm3 in the upper thoracic esophagus was considered as target, and phantom planned computed tomography (CT) for HDR brachytherapy, then with a micro-Selectron HDR (192Ir) remote after-loading unit. Results: Absorbed doses were measured with calibrated TLDs and were expressed in centi-Gray (cGy). In regions far from target (≥ 16 cm) such as submandibular, parotid and thyroid glands, mean measured dose ranged from 1.65 to 5.5 cGy. In closer regions (≤ 16 cm), the absorbed dose might be as high as 113 cGy. Conclusions: Our study showed similar depth and surface doses; in closer regions, the surface and depth doses differed significantly due to the role of primary radiation that had imposed a high-dose gradient and difference between the plan and measurement, which was more severe because of simplifications in tissue inhomogeneity, considered in TPS relative to phantom.

Abstract
PURPOSE To compare the efficacy and the incidence of complications of high-dose-rate (HDR) and low-dose-rate (LDR) intraluminal brachytherapy (IBT) boost after external beam radiation therapy in patients with superficial esophageal cancer. METHODS AND MATERIALS Fifty-four consecutive patients with Stage I thoracic esophageal squamous cell carcinoma who were treated with definitive radiotherapy using IBT between 1991 and 2007 were studied retrospectively. LDR-IBT and HDR-IBT were performed for 19 and 35 patients, respectively. After external beam radiation therapy of 56-60 Gy with a conventional fractionation, LDR-IBT (5 Gy × 2) or HDR-IBT (3 Gy × 3) was given within 2 weeks. The median follow-up was 47 months (7-151 months). RESULTS Overall, the 5-year overall survival, cause-specific survival (CSS), and locoregional control (LRC) rates were 61%, 86%, and 79%, respectively. The 5-year overall survival, CCS, and LRC rates did not differ significantly between the LDR-IBT and HDR-IBT groups (68% vs. 58% (p=0.50), 83% vs. 85% (p=0.63), and 84% vs. 75% (p=0.42), respectively). Salvage treatment was given in 8 locally recurrent patients, and 6 patients were rescued. The Grade ≥2 late morbidities of esophagus and heart/lung were observed in 5 patients (4 in the LDR-IBT group and 1 in the HDR-IBT group) and 2 patients (one from each group), respectively. CONCLUSIONS In view of the safety profile and effectiveness, our results encourage the continued adoption of HDR-IBT as radiation boost in medically inoperable or elderly superficial esophageal cancer patients undergoing definitive radiotherapy.

Abstract
BACKGROUND The number of elderly patients with oesophageal cancer is expected to increase with the aging of the population and the rapidly increasing incidence of adenocarcinoma. Surgical resection is standard treatment for patients with localized disease considered fit for operation. However, elderly patients with oesophageal cancer are rarely referred for surgery. The aim of this prospective, single-arm, phase II study was to evaluate the feasibility and efficacy (tumour response) of chemoradiotherapy in the treatment of elderly patients with localized oesophageal cancer. Secondary endpoints were progression-free survival (PFS) and quality of life (QOL). METHODS The main study inclusion criteria were: patients aged >or=75 years; oesophageal cancer disease stage II-III; Charlson co-morbidity index score <or=4; Eastern Cooperative Oncology Group (ECOG) performance status 0-2; and weight loss <15%. The radiotherapy regimen consisted of 50 Gy over 5 weeks. Cisplatin 75 mg/m2 was given on days 1 and 21 of radiotherapy. Complete response was defined as disappearance of the tumour at endoscopy and/or at oesophagography and CT scan. Written informed consent was obtained from all patients. A three-step Fleming design was used to calculate the sample size. RESULTS Twenty-two patients were included in the study between March 2000 and June 2004; this sample size was sufficient to allow conclusions to be drawn from the study. The mean age of the patients was 79.4 years (range 75-89 years), 18 were male (81.8%), 15 had squamous cell carcinoma (68%) and 11 had stage IIA disease (50%). The mean Charlson co-morbidity index score was 1. All patients were compliant with the planned treatment, including doses and timing. During treatment, ECOG performance status remained stable during the first 3 weeks and worsened slightly over the last 2 weeks. Dysphagia remained stable. Five patients (22%) had transient grade 2 vomiting after the second cisplatin injection. No patient experienced nephrotoxic adverse effects and there were no toxicity-related deaths. Six weeks after treatment, 14 patients were in complete response (63.6%) and 8 patients (36.4%) had no treatment effect. The overall survival was 81.6% at 6 months and 62.4% at 1 year. The PFS at 1 year was 50%. Four patients (18.2%) were alive without disease from 2.6 to 5.5 years after treatment. In 14 evaluable patients, QOL 6 weeks after treatment was slightly altered by treatment. CONCLUSIONS The results of this prospective phase II study support the feasibility of chemoradiotherapy for oesophageal cancer in carefully selected elderly patients, with the potential for a curative effect.

Abstract
OBJECTIVE To evaluate technical feasibility and acute and subacute radiotolerance of a self-expandable stent loaded with (125)I seeds in the rabbit esophagus. METHODS A self-expandable stent designed for esophageal application was made of 0.16mm nitinol wire and loaded with (125)I seeds (CIAE-6711). Twenty-seven stents with three different radioactive dosages (n=9 in each dosage group) were implanted in the esophagus of healthy rabbits, while nine stents alone were used as controls. The stents were perorally deployed into the esophagus under fluoroscopic guidance. Radiological follow-up included plain chest film, CT scan, and barium esophagography which were undertaken in all rabbits of each group at 2, 4, and 8 weeks, respectively, which were correlated to histopathological findings. The stented esophageal segments along with their adjacent tissues were harvested for histopathological examinations. RESULTS The stent was successfully deployed into the targeted esophageal segment in all rabbits. Neither (125)I seeds dislodged from the stent during the deployment, nor they did during the follow-up period. The greatest (16.2Gy) absorbed dose was found in the tissue 10mm from (125)I seeds at 8 weeks. Slight epithelial hyperplasia on the stent surface and submucosal inflammatory process developed at 2 weeks, which reached the peak at 8 weeks after the procedure. Significant thickness of the esophageal muscular layer was found at 8 weeks only in the groups with (125)I seeds. On radiologic follow-up, moderate strictures on both ends of the stents developed at 4 weeks and became severe at 8 weeks after the procedure in all groups. CONCLUSION Deployment of a self-expandable stent loaded with (125)I seeds is technically feasible and safe within the first 8 weeks. Acute and subacute radiotolerance of the treated esophagus and its adjacent tissues by (125)I seeds is well preserved in a healthy rabbit model.

Abstract
PURPOSE The aim of this study was to retrospectively evaluate the feasibility, efficacy, and tolerance of external beam radiotherapy followed by high-dose-rate brachytherapy in inoperable patients with superficial esophageal cancer. PATIENTS AND METHODS From November 1992 to May 1999, 66 patients with superficial esophageal cancer were treated with exclusive radiotherapy. The median age was 60 years (range, 41-85). Fifty-three percent of them were ineligible for surgery owing to synchronous or previously treated head-and-neck cancer. Most of the patients (n = 49) were evaluated with endoscopic ultrasonography (EUS) or computed tomography (CT). The mean doses of external beam radiotherapy and high-dose rate brachytherapy were 57.1 Gy (+/-4.83) and 8.82 Gy (+/-3.98), respectively. The most frequently used regimen was 60 Gy followed by 7 Gy at 5 mm depth in two applications. RESULTS Among patients evaluated with EUS or CT, the complete response rate was 98%. The 3-, 5-, and 7-year survival rates were 57.9%, 35.6%, and 26.6%, respectively. Median overall survival was 3.8 years. The 5-year relapse-free survival and cause-specific survival were 54.6% and 76.9%. The 5-year overall, relapse-free, and cause-specific survival of the whole population of 66 patients was 33%, 53%, and 77%, respectively. Local failure occurred in 15 of 66 patients; 6 were treated with brachytherapy. Severe late toxicity (mostly esophageal stenosis) rated according to the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer scale occurred in 6 of 66 patients (9%). CONCLUSION This well tolerated regimen may be a therapeutic alternative for inoperable patients with superficial esophageal cancer. Only a randomized study could be able to check the potential benefit of brachytherapy after external beam radiation in superficial esophageal cancer.

Abstract
PURPOSE In 1991, we started a clinical prospective trial for operable esophageal carcinoma, foreseeing organ preservation, to assess the treatment results after definitive chemoradiotherapy (CRT) for clinical Stage I (T1N0M0) esophageal cancer. PATIENTS AND METHODS Between 1992 and 2003, 63 patients were enrolled in this study. Tumor depth was mucosal cancer (T1a) in 23 and submucosal cancer (T1b) in 40. CRT consisted of 55-66 Gy/50-60 fractions (median, 59.4 Gy); from 1 to 3 cycles (median, 2) of concurrent chemotherapy (Cisplatin and 5-fluorouracil), followed by high-dose-rate intraluminal brachytherapy 10-12 Gy/2-3 fractions. RESULTS The 5-year overall and cause-specific and disease-free survival rates were 66.4%, 76.3%, and 63.7%, respectively. The 5-year cause-specific survival rates for T1a and T1b cancer patients were 85.2% and 70.0%, respectively (p = 0.06). The 5-year disease-free survival rates for T1a and T1b were 84.4% and 50.5%, respectively (p < 0.01). Esophageal fistula as a late toxicity occurred in 2 patients (G4: 1; G5: 1), and esophageal stricture requiring a liquid diet occurred in 2 patients. Pericardial effusion was observed in 3 patients. CONCLUSION We confirmed that patients with T1N0M0 esophageal carcinoma had their esophagus preserved in 89.2% of cases after definitive CRT, and the survival rates were equivalent to those of previous reports of surgery.

Abstract
PURPOSE To assess the safety and efficacy of external beam radiotherapy for elderly patients with esophageal cancer. METHODS AND MATERIALS A trial testing external beam radiotherapy (66 Gy within 6.5 weeks) as a single-modality treatment was performed for biopsy-proven squamous cell carcinoma of the thoracic esophagus clinically staged as Stage I and IIA (T1-T3N0M0, International Union Against Cancer, 1987) in patients aged > or =80 years. RESULTS From January 1999 through December 2002, 51 evaluable patients (35 men and 16 women) with a median age of 83 years (range, 80-91 years) were enrolled from 22 institutions. Of the 51 patients, 18 (35%) had Stage T1 and 33 (65%) had Stage T2-T3 disease. Radiotherapy could be completed in 47 patients (92%) within 43-58 days (median, 49). The actuarial incidence of Grade 3 or worse cardiopulmonary complications at 3 years was 26%, with 3 early deaths, and correlated significantly with the size of the anteroposterior radiotherapy portals. The median survival time and overall survival rate at 3 years was 30 months and 39% (95% confidence interval, 25-52%), respectively. CONCLUSION The results of high-dose radiotherapy in octogenarians are comparable to those in younger patients, but meticulous treatment planning and quality control is required.

METHODS AND MATERIALS Patients without evidence of metastatic disease were identified. HDRBT was given before ERT with a dose of 20 Gy in 5 fractions. Patients with a Karnofsky performance of more than 70 received treatment with 50 Gy in 25 fractions and concurrent 5-fluorouracil and cis-platinum during Weeks 1 and 5, whereas patients with a Karnofsky performance of less than 70 were treated with radiation therapy alone with 35 Gy in 14 fractions. RESULTS Fifty-three patients received HDRBT treatment with combined ERT and chemotherapy and 17 patients with ERT alone. The incidence of acute bone marrow toxicity was 55% Grade 2 and 15% Grade 3, and 85% of patients had Grade 2 esophagitis. With a median follow-up time of 26 months, the median survival was 21 months; the 2-year local recurrence was 25%, and the 5-year survival rate was 28%. CONCLUSION HDRBT is safe and beneficial for local control in the radical treatment of patients with esophageal cancer.

Abstract
PURPOSE To analyze retrospectively the long-term results of external beam radiotherapy (RT) with or without intraluminal brachytherapy (ILBT) for patients with Stage I esophageal cancer. METHODS AND MATERIALS A total of 34 patients with esophageal squamous cell carcinoma, clinically diagnosed as having Stage I disease, were treated with definitive RT, with or without ILBT. The median age was 69 years. Seven patients were treated with external beam RT alone (median, 64 Gy), and 27 were treated with external beam RT (median, 52 Gy) plus ILBT (8-12 Gy in two to three fractions). RESULTS The 5-year overall survival, local relapse-free survival, and cause-specific survival rate was 58.9%, 68.4%, and 80.0%, respectively, with a median follow-up of 61 months. Of 9 patients with local recurrence after initial therapy, 7 were successfully treated, and the 5-year cumulative rate of esophagectomy was 19.6%. The 2-year local relapse-free rate for patients with and without ILBT was 79.1% and 53.6%, respectively. CONCLUSION Although local recurrence was frequent within 2 years, the disease-specific survival rate was high owing to effective salvage therapy. Definitive RT is a reasonable treatment option for highly comorbid and elderly patients with Stage I esophageal cancer. The role of ILBT needs to be clarified.

Abstract
PURPOSE To assess the clinical effectiveness of temporary metallic stent placement with concurrent radiation therapy in patients with esophageal carcinoma by comparing it with permanent stent placement with concurrent radiation therapy. MATERIALS AND METHODS Covered retrievable expandable nitinol stents were placed in 47 patients with esophageal carcinoma 1 week before starting radiation therapy; the stents were electively removed 4 weeks after placement in 24 patients (group A), while not electively removed in the other 23 patients (group B). In cases of complications, the stents were also removed from patients in groups A and B. The dysphagia score, complications (severe pain, granulation tissue formation, stent migration, esophagorespiratory fistula, and hematemesis), tumor overgrowth/regrowth, reintervention rates, and dysphagia-progression-free and overall survival rates were compared in the two groups. RESULTS Stent placement or removal was technically successful and well tolerated in all patients. The dysphagia score was significantly improved in both groups after stent placement (P < .01). Each of the stent-related complications was less in group A than in group B but there was no significant difference. However, the total number of patients with one or more than one complications and who needed related reinterventions was significantly less in group A than in group B (P = .042 and .030, respectively). Tumor overgrowth/regrowth and the total number of patients who required related reinterventions was not significantly different (P = 1.00 and .517, respectively). Dysphagia-progression-free and overall survival rates were significantly longer in group A than in group B (P = .005 and .001, respectively). CONCLUSION Temporary placement of a covered retrievable expandable metallic stent with concurrent radiation therapy for patients with esophageal carcinoma is beneficial for reducing complications and related reinterventions and for increasing resultant survival rates compared with permanent esophageal stent placement.

Abstract
To evaluate patient characteristics and treatment factors influencing outcome of patients treated with definitive radiotherapy, we performed retrospective analysis. From 1983 to 2000, 154 patients who were diagnosed as esophageal carcinoma without distant metastasis received definitive radiotherapy with (N = 90) or without (N = 64) systemic chemotherapy. One hundred forty-two males and 12 females were entered in the analysis. Thirty-four patients received an additional boost of intracavitary brachytherapy (ICBT). The median patient age was 68 years (range: 46-86). Disease stage was distributed as stage I, II, III, and IV for 33, 42, 33, and 45 patients, respectively. External beam radiotherapy was prescribed with a median 63 Gy (range: 38-77.8 Gy). The 2- and 5-year overall survival (OAS) and local control (LC) rates were 40.8/18.4% and 48.6/28.9%, respectively. In uni-/multivariate analyses, significant prognostic factors of OAS proved to be advanced T stage, absence of ICBT, and age less than 65 years. As for LC, adverse prognostic factors of uni/multivariate analysis were advanced T stage and poor performance status. The pretreatment T stage showed the most powerful influence on both survival and LC. Combination use of ICBT is proven to refine treatment outcome, although eligible criteria should be decided by a prospective study.

Abstract
PURPOSE To assess the efficacy, toxicity, and the optimum dose of high-dose-rate brachytherapy following chemoradiotherapy (CRT) compared with a historical group of patients treated with a combination of external beam and brachytherapy (RT alone). METHODS AND MATERIALS Fifty-three patients with localized esophageal cancer received concurrent chemoradiotherapy followed by brachytherapy. The chemotherapy regimen was a combination of cisplatin 60 mg/m2 on day 1 and fluorouracil 600 mg/m2 continuous infusion from days 1-4 during the first and last week of external irradiation. Radiotherapy consisted of external irradiation to a total dose of 40-61 Gy (median 50 Gy) and brachytherapy to 8-24 Gy (median 16 Gy) in 2-4 fractions. RESULTS Acute toxicity was well tolerated. A fistula occurred in one patient 1 week after completion of external irradiation. Local control was achieved in 32/53 (60%) compared with 42% of the RT group (p = 0.029). Local control rates of the CRT group were significantly better than those of the RT group in Stages II and III. Late toxicity (esophageal ulceration and strictures) occurred in 18 (34%) of the CRT group compared with 12% in the RT group (p = 0.013). Severe late toxicity (RTOG/EORTC criteria Grade 3-4) occurred in six patients (15%) whose chemotherapy was followed by 16-24 Gy via brachytherapy compared with 2.5% in the RT group (p = 0.010). CONCLUSION Combined chemoradiotherapy and brachytherapy boost achieved better local control than radiotherapy alone. However, a high level of severe late toxicity was observed especially with 16-24 Gy via brachytherapy.
