Moderately Hypofractionated Intensity-modulated Radiotherapy With a Simultaneous Integrated Boost for Locally Advanced Head and Neck Cancer - Do Modern Techniques Fulfil Their Promise? In Vivo 2021; 35:2801-2808. [PMID: 34410971 PMCID: PMC8408698 DOI: 10.21873/invivo.12566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 05/30/2021] [Accepted: 05/31/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND Intensity-modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB) and moderate hypofractionation offers an opportunity for defining individual doses and a reduction in overall treatment time in locally advanced head and neck cancer (HNSCC). We present retrospective data on toxicity and locoregional control of a patient cohort treated with an IMRT-SIB concept in comparison to normo-fractionated 3D-conformal radiotherapy (3D-RT). PATIENTS AND METHODS Between 2012 and 2014, 67 patients with HNSCC (stages III-IVB) were treated with IMRT-SIB either definitively or in the postoperative setting. These patients were matched with those of patients treated with normo-fractionated 3D-RT before mid-2012 and their clinical courses were compared. Chemotherapy or cetuximab was given concomitantly in both groups in the definitive situation (postoperatively, dependent on risk factors). RESULTS Significantly less toxicity was found in favor of IMRT-SIB concerning dysphagia, dermatitis, xerostomia, fibrosis, and lymphedema. After a median follow-up of 31 months (range=2-104 months), 3-year locoregional control was 73% for those treated with IMRT-SIB versus 78% for those treated with 3D-RT. CONCLUSION This moderately hypofractionated IMRT-SIB concept was shown to be feasible, incurring less toxicity than conventional 3D-RT.

Role of nano-sensitizers in radiation therapy of metastatic tumors. Cancer Treat Res Commun 2021; 26:100303. [PMID: 33454575 DOI: 10.1016/j.ctarc.2021.100303] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 12/30/2020] [Accepted: 01/04/2021] [Indexed: 12/13/2022]
Abstract
Cancer metastasis remains the major cause of global cancer deaths. Radiation therapy remains one of the golden standards for cancer treatment. Nanomedicine based strategies have been designed and developed in order to improve the clinical outcomes of cancer therapy and diagnosis at molecular levels. Over the years, several researchers have shown their interest in using radiosensitizers made of high Z elements. Metal-based nanosystems also play a dual role by enhancing the synergistic effect of cell killing via various biological immune responses. This review summarizes the role of Nano-sensitizers in boosting radiation (ionizing/non-ionizing radiations) induced biological responses in treatment of metastatic cancer models.

[PMID: 32156457 DOI: 10.1016/j.canrad.2020.01.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 01/06/2020] [Accepted: 01/28/2020] [Indexed: 12/21/2022]
Abstract
PURPOSE The optimal dose in esophageal cancer patients treated with definitive chemoradiation (CRT) remains debated. We herein report on the dosimetric results, treatment-related toxicities and long-term outcomes of escalated dose up to 60Gy delivered with intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS All consecutive patients that received a definitive CRT>50Gy for an unresectable esophageal carcinoma between 2010 and 2015 were retrospectively evaluated for this study. Methodology included data base search, delayed toxicity grading, statistical testing including frequency analysis and survival analysis. RESULTS A total of 51 patients were irradiated for a squamous cell carcinoma (86.3%) or an adenocarcinoma (13.7%). The median age at diagnosis was 62 years. Seven patients were simultaneously irradiated for another synchronous primary tumor. Forty-six patients (90.2%) received concurrent platin-based chemotherapy. The median prescribed doses were 60Gy (54-66) and 48Gy (44.8-56) delivered in 30 (27-35) fractions to the high and the low risks PTV respectively. The mean dose delivered to the lungs was 11.4Gy (IC 95%: 4.8-19.8), the median volumes receiving up to 20Gy (V20) and 30Gy (V30) were 13.5% (3.0-46.0) and 4.6% (0.7-19.8) respectively. The mean dose delivered to the heart was 13.9Gy (IC 95%:0.3-31.3) with a median V40 of 3.3% (0.0-25.0). One treatment-related death occurred within days after RT completion (neutropenic aplasia). After a median follow-up of 2.7 years (95% CI: 1.9-4.3), the 2-year overall survival, disease free survival and loco-regional control rates were 53.6%, 42.0% and 72.8% respectively. Delayed treatment related-toxicities ≤grade 3 occurred among 25 patients (62.5%) mostly esophageal stricture (79.2%). CONCLUSION We demonstrated in this study that dose escalation using IMRT in combination with platin-based chemotherapy as a definitive treatment for esophageal carcinoma is safe and results in higher loco-regional and control survival when compared to previously reported data.

Influencing Factors on Radiotherapy Outcome in Stage I-II Glottic Larynx Cancer-A Multicenter Study. Front Oncol 2019; 9:932. [PMID: 31616637 PMCID: PMC6763757 DOI: 10.3389/fonc.2019.00932] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Accepted: 09/05/2019] [Indexed: 11/13/2022] Open
Abstract
Background and Purpose: Larynx cancer represents one of the most frequently diagnosed head and neck malignancies, which is most often confined to the glottic area. The aim of this study was to report the oncological outcome and identify prognostic factors in early-stage glottic squamous cell carcinoma treated with radiotherapy. Material and Methods: Patients (n = 761) diagnosed and treated in 10 centers between 1990 and 2015 were retrospectively analyzed. Probabilities of loco-regional control (LRC) and overall survival (OS) were calculated and possible prognostic factors were analyzed using Cox proportional hazards models. Results: The median follow-up was 63 months (range: 2-243). Three hundred and sixty-four, 148 and 249 patients had cT1a, cT1b, and cT2 stage I-II disease, respectively. Five and 10-years LRC/OS rates in the whole cohort were 83/82% and 80/68%, respectively. Three patients developed distant recurrences. In univariate analysis, male sex (HR: 3.49; 95% CI: 1.47-11.37; p < 0.01), T2 vs. T1a (HR: 1.62; 95% CI: 1.08-2.43; p = 0.02) and anterior commissure involvement (ACI) (HR: 1.66; 95% CI: 1.38-2.45; p < 0.01) were associated with impaired LRC. In multivariate analysis, male sex (HR: 3.42; 95% CI: 1.44-11.17; p < 0.01) and ACI (HR: 1.51; 95% CI: 1.01-2.28; p = 0.047) remained poor prognostic factors. No relation of treatment technique and biologically equivalent dose (BED) to oncological outcome was identified except for higher BED10(L = 25; T = 1) yielding better LRC in T1a tumors (p = 0.04) in univariate analyses. Conclusion: Our results highlight the negative impact of ACI on tumor control. A less-expected finding was the impact of sex on tumor control. Further research is needed to validate its prognostic value and investigate any related biologic or behavioral factors, which may be modified to improve oncologic outcome.

Abstract
BACKGROUND The decision between definitive radio(chemo)therapy (RCT) or a surgical strategy, i. e. surgery ± adjuvant radio(chemo)therapy for optimal treatment of oropharyngeal cancer is highly debated. Human papillomavirus(HPV)-related tumours are a distinct entity associated with p16 overexpression. While this represents a major prognostic factor, its predictive significance remains unknown. RESULTS Among 183 consecutive unselected patients treated between 2009 and 2013 with a state-of-the-art surgical procedure ± adjuvant radio(chemo)therapy or definitive RCT including intensity-modulated radiotherapy, 3‑year disease-free survival (DFS) was 74 vs. 57%, respectively (p = 0.007). When focusing on p16+ patients (49%), there was no significant difference in tumour control rate between surgery ± radio(chemo)therapy and the definitive RCT group (3-year DFS 83 vs. 82%, respectively; p = 0.48). However, delayed severe dysphagia was significantly lower in favour of definitive RCT: 35 vs. 4%, respectively; p = 0.0002. CONCLUSION Our results highlight distinct outcomes after definitive RCT or initial surgical treatment according to p16 status, which should thus be considered during the decision process.

Abstract
BACKGROUND Technological advances in radiotherapy have allowed investigations into new methods to spare healthy tissue in those treated for head and neck cancer. This systematic review with meta-analysis demonstrates the effect that radiation has on swallowing. METHODS Selection and analysis of studies examining the effect of radiation to swallowing structures. A fixed effects meta-analysis calculated the pooled proportions for select outcomes of dysphagia, common across many studies. RESULTS The majority of the papers found a correlation between radiation dose to the swallowing structures and dysphagia, however a meta-analysis found the studies carried a significant degree of heterogeneity. The appraisal demonstrates the need for large-scale studies using a randomized design and instrumental dysphagia assessments. CONCLUSIONS Radiation dose to dysphagia and aspiration structures is correlated with incidence of dysphagia and aspiration. The variables in this population contribute to the heterogeneity within and cross studies and future studies should consider controlling for this.

Abstract
To study the survival in patients affected with hypopharyngeal cancer among treatment groups and different stages. Data of hypopharyngeal cancer patients diagnosed from 1st January 2010 to 31st December 2010 was used in the present study. The cases were analyzed for gender, age group distribution, sub-sites at presentation, stage at diagnosis and the type of treatments. Survival from the date of first diagnosis was estimated and hazard ratios were calculated. Survival probability and hazards ratios (HR) were calculated by Kaplan-Meier method and Cox-proportional regression analysis respectively. Censoring of patient who survived longer than 5 years was done. Active follow-up was done for the survival analysis. The study cohort included 217 patients and treatment compliance was observed in 46.9% of cases. The median age at diagnosis was 57 years (range 24-90), 86.2% of cases were locally advanced cases (stage III and IV), pyriform sinus was major sub-site (96%), radiotherapy was main treatment modality alone in 84.8% of cases, median survival was 31 months and 5-year overall survival was 36.9%, and HR for stage IV was 1.9 (P = 0.03, 95% CI - 1.04 to 3.7). In developing setting of North East India, radiotherapy was the main modality of treatment for hypopharyngeal cancer patients, and understanding the clinical parameters and survival of this group of cancers is crucial for its control.

Abstract
Objectives To compare overall survival (OS) in locally advanced hypopharyngeal cancer treated with surgery or definitive chemoradiotherapy in the contemporary era. Methods From 2010 to 2015, data for patients diagnosed with hypopharyngeal cancer (T2‐T4aM0) and treated with total pharyngectomy with lymph node dissection (surgery group) or definitive radiotherapy and chemotherapy (chemoradiotherapy group) was retrieved from the SEER database. Multivariate analyses were performed in each subgroup divided according to T category (T2‐3 or T4a). Results The number of patients in the surgery and chemoradiotherapy groups was 209 and 648, respectively. Among them, the number of T4a patients was 111 and 126 in each group. Three‐year OS rate in the surgery and chemoradiotherapy groups was 37.9% and 44.1%, respectively (P = 0.178). The 3‐year OS rate for the T2‐3 patients was 46.5% and 48.7% (P = 0.598), and the 3‐year OS rate for the T4a patients was 29.9% and 26.1% in the surgery and chemoradiotherapy groups, respectively (P = 0.439). On multivariate analysis, the chemoradiotherapy group was not inferior to the surgery group in T2‐T4a patients (Hazard ratio [HR] for the chemoradiotherapy group 0.889, 95% confidence interval [CI] 0.699‐1.129, P = 0.334), in T2‐3 patients (HR 0.932, 95% CI 0.699‐1.297, P = 0.675), and in T4a patients (HR 0.880, 95% CI 0.617‐1.256, P = 0.481). Conclusions Chemoradiotherapy for locally advanced hypophagyngeal cancer showed a comparable OS rate to surgery. For patients with T4a category cancer with high possibility of preserving the laryngopharyngeal function, chemoradiotherapy may be a promising alternative treatment.

Abstract
BACKGROUND The optimal treatment strategy for stage I-II glottic squamous cell carcinoma (SCC) is not well-defined. This study analyzed treatment results and prognostic factors. PATIENTS AND METHODS This is a single-institution retrospective analysis of 244 patients with T1-2 glottic SCC who underwent normofractionated radiotherapy (RT) and/or surgery between 1990 and 2013. The primary endpoint was relapse-free survival (RFS). RESULTS Median age was 65 years (range: 36-92 years), the majority (82%) having stage I disease. Definitive RT was used in 82% (median dose: 68 Gy, 2 Gy per fraction). Median follow-up was 59 months. The 5‑year RFS rates were 83 and 75% (p = 0.05) for stage I and 62 and 50% (p = 0.47) for stage II in the RT and surgery groups, respectively. Multivariate analyses indicate T1 vs. T2 and RT vs. surgery as independent prognostic factors for RFS, with hazard ratios of 0.38 (95% confidence interval, CI: 0.21-0.72) and 0.53 (95% CI: 0.30-0.99), respectively (p < 0.05). The 5‑year overall and cause-specific survival rates in the whole cohort were 92 and 96%, respectively, with no significant differences between treatment groups. Anterior commissure involvement was neither a prognostic nor a predictive factor. The incidence of secondary malignancies was not significantly different between patients treated with and without RT (22 vs. 9% at 10 years, respectively, p = 0.18). CONCLUSION Despite a possible selection bias, our series demonstrates improved RFS with RT over surgery in stage I glottic SCC.

Abstract
PURPOSE To assess the outcome of locally advanced medullary thyroid carcinoma treated with surgery and adjuvant external beam radiotherapy. PATIENTS AND METHODS Twenty-nine consecutive patients with non-metastatic medullary thyroid carcinoma treated in our institution between January 1995 and December 2012 were retrospectively evaluated. All underwent curative-intended optimal surgery, followed by external beam radiotherapy because of high risk of locoregional relapse. Twelve patients were stage III, 16 IVa and 1 IVb. Positive surgical margins were present in 11 cases (10 R1 and 1 R2). Median and average preradiotherapy serum calcitonin were 141pg/mL and 699pg/mL, respectively. Fourteen patients received 3D-conformal radiotherapy and 15 received intensity-modulated radiotherapy. Median prescribed dose was 63Gy to the high-risk volumes and 54Gy to the low-risk volumes. Treatment was delivered in 30 fractions. The median gap between surgery and radiotherapy was 1.9months. Median follow-up was 76.4months. RESULTS Kaplan-Meier estimates of 5-year locoregional relapse-free survival and overall survival were 79 and 96 %, respectively. Among the five locoregional relapses, two were related to a macroscopic metastatic cervical lymph node that was unfortunately not removed during the lymphadenectomy. Eight of ten patients with microscopic positive margins (R1) were controlled regarding the thyroidectomy bed. Eight patients had normal serum calcitonin after external beam radiotherapy, of whom only one developed a locoregional relapse during follow-up. Regarding the 21 patients with persistent positive serum calcitonin after treatment, only ten developed a macroscopic locoregional or distant relapse. One grade III and no grade IV acute morbidity were reported. Fifteen patients reported grade II chronic morbidity and no grade III/IV. CONCLUSION Maximal surgery followed by adjuvant external beam radiotherapy as a treatment for locally advanced medullary thyroid carcinoma provides a high rate of long-term locoregional control and overall survival with limited toxicity. Postoperative external beam radiotherapy should be considered when patients present features indicating a high risk of locoregional relapse.

Abstract
AIM The purpose of this work was to compare sequential (SeqB) versus simultaneous integrated boost (SIB) radiotherapy plans delivered with volumetric modulated arc therapy (VMAT) for patients with locally advanced squamous cell cancer of the head and neck (HNSCC). PATIENTS AND METHODS SeqB and SIB plans using VMAT for 10 HNSCC patients given definitive chemoradiation were generated and analysed for differences in dose distribution, coverage, conformity and homogeneity to the planning target volumes (PTV) 1-3 and sparing of organs at risk (OAR). RESULTS The mean delineated volumes ± standard deviations were 137.7 ± 44.8, 351.3 ± 83.9 and 895.6 ± 120.5 cm3 for PTV1-3. The mean volumes encompassed by the corresponding 95 % isodoses were 281 (+ 110 %) ± 73.4, 712.2 (+ 115 %) ± 146.4 and 1381.1 (+ 54 %) ± 217.3 cm3 with SeqB and 138.2 (+ 7 %) ± 40.1, 380.4 (+ 11 %) ± 91.9 and 1057.3 (+ 21 %) ± 161.4 cm3 with SIB for PTV1-3, respectively. Both strategies achieved excellent PTV coverage. SeqB provided significantly better coverage of PTV1 and 3, worse conformity for PTV1-3 and a higher mean dose than prescribed (111-115 %) to PTV2 and 3 (p ≤ 0.007). Both strategies provided satisfactory OAR sparing. CONCLUSION This study showed significant dosimetric differences with potential clinical relevance between two VMAT boost strategies regarding coverage, conformity and dose to the PTVs. SIB might cause less toxicity. A clinical phase III/IV trial endorsed by the German Head and Neck Clinical Trials Group (IAG-KHT) will evaluate differences in acute/late toxicity as well as in locoregional recurrences between the two boost techniques.

Lipiodol injections for optimization of target volume delineation in a patient with a second tumor of the oropharynx: A case report. Strahlenther Onkol 2015; 191:681-6. [PMID: 26040498 DOI: 10.1007/s00066-015-0856-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2015] [Accepted: 05/13/2015] [Indexed: 02/08/2023]
Abstract
BACKGROUND Lipiodol injections were administered in the head and neck area to improve gross tumor volume (GTV) definition for small-volume re-irradiation of a 63-year-old previously irradiated patient with a second tumor of the oropharynx in the posterior wall with longitudinal ligament infiltration (cT4cN0cM0). METHODS The patient had dialysis-depending renal failure. On diagnostic computed tomography (CT), which was performed with intravenous contrast agent, the tumor in the oropharynx was not detectable. Because of dialysis-depending renal failure comorbidity, no contrast agent was applied in the planning CT and in the diagnostic magnetic resonance imaging (MRI) study. In each cross-sectional imaging study performed, the GTV, especially in craniocaudal extensions, was not safely delineable. Therefore, craniocaudal tumor margins were pharyngoscopically marked with Lipiodol injections, an iodine-containing contrast agent. RESULTS In a second planning CT, the GTV could be defined with the help of the Lipiodol marks and small-volume re-irradiation was performed. No Lipiodol-associated side effects occurred in the patient. CONCLUSION In the present case, the use of Lipiodol injections at the tumor margins facilitated the definition of the GTV.
