Role of primary tumor volume and metastatic lymph node volume in response to curative effect of definitive radiotherapy for locally advanced head and neck cancer. Eur J Med Res 2024; 29:98. [PMID: 38311769 PMCID: PMC10840279 DOI: 10.1186/s40001-024-01691-0] [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: 09/02/2023] [Accepted: 01/20/2024] [Indexed: 02/06/2024] Open
Abstract
BACKGROUND Studies have shown mixed results concerning the role of primary tumor volume (TV) and metastatic lymph node (NV) volume in response to the curative effect of definitive radiotherapy for locally advanced head and neck squamous cell carcinoma (LAHNSCC). OBJECTIVE We aimed to evaluate the impact of TV and NV on the efficacy of radical radiotherapy in LAHNSCC patients, with the goal of guiding individualized therapy. PATIENTS AND METHODS Patients with LAHNSCC who received radical radiation therapy and were reexamined within 6 months post-therapy from January 2012 to December 2021 were selected. The volumes of the primary tumors and metastatic lymph nodes were calculated by software and then were divided into a large TV group vs small TV group and a large NV group vs small NV group according to the relationship with the median. Additionally, patients who received concurrent chemoradiotherapy (CCRT) or not were divided into the CCRT group and the radiotherapy (RT) group. Patients with lymph node metastasis were divided into node concurrent chemotherapy (N-CCRT) group and a node metastatic chemotherapy (N-RT) group according to whether they received concurrent chemotherapy or not. The volume shrinkage rate (VSR), objective response rate (ORR), local control rate (LCR) and overall survival (OS) were recorded and analyzed. RESULTS 96 patients were included in the primary tumor volume group, and 73 patients were included in the metastatic lymph node group. Receiver operating characteristic (ROC) curves were constructed for objective remission (OR) endpoints, and a volume threshold was defined for TV and NV patients. The threshold primary tumor volume was 32.45 cm3, and the threshold metastatic lymph node volume was 6.05 cm3.The primary TV shrinkage rates of the small TV and the large TV groups were basically the same, P = 0.801. Similarly, the ORR and LCR were not significantly different between the small TV group and the large TV group (PORR = 0.118, PLCR = 0.315). Additionally, the TV shrinkage rate did not significantly differ between the CCRT group and the RT group, P = 0.133. Additionally, there was no significant difference in ORR or LCR in CCRT group (PORR = 0.057, PLCR = 0.088). However, the metastatic lymph node volume shrinkage rate in the small NV group was significantly greater than that in the large NV group (P = 0.001). The ORR and LCR of the small NV subgroup were significantly greater than those of the large NV subgroup (PORR = 0.002, PLCR = 0.037). Moreover, compared with that of the N-RT group, the NV shrinkage rate of the N-CCRT group was 84.10 ± s3.11%, and the shrinkage rate was 70.76 ± s5.77% (P = 0.047). For the ORR and LCR, the N-CCRT group and N-RT group were significantly different (PORR = 0.030, PLCR = 0.037). The median OS of the whole group was 26 months. However, neither TV/NV nor concurrent chemotherapy seemed to influence OS. CONCLUSION Primary tumor volume is not a prognostic factor for the response to curative effect radiotherapy in LAHNSCC patients. Nevertheless, metastatic lymph nodes are a prognostic factor for the response to curative effect radiotherapy in LAHNSCC patients. Patients with smaller lymph nodes have better local control.

J Cancer Res Ther 2024; 20:375-382. [PMID: 38554349 DOI: 10.4103/jcrt.jcrt_2178_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Accepted: 11/24/2022] [Indexed: 04/01/2024]
Abstract
BACKGROUND To retrospectively access outcome, adverse events and prognostic factors in oropharyngeal carcinoma (OPC) patients treated with intensity-modulated radiotherapy (IMRT). METHODS Ninety-eight OPC patients were treated between 2000 and 2015. Thirty-three patients received definitive and 65 adjuvant radiotherapy. Seventy-one percent had simultaneous chemotherapy. Patients were systematically followed up (mean 114 months, range 19-197 months). Statistical analysis used Kaplan-Meier method, Cox regression analysis, and log-rank test. Adverse events were classified according to common toxicity criteria version (CTCAE) 4.03. RESULTS The 1-, 5-, and 10-year overall survival rates in the adjuvant vs. definitive cohort were 90.8% vs. 66.7%, 67.4% vs. 33.1%, and 57.7% vs. 16.5%. Survival in the adjuvant cohort was significantly longer than in the definitive cohort (P < 0.00005). Patients <65 years had a significantly longer survival than older patients. Locoregional tumor control rates after 1-, 5-, and 10 years in the adjuvant vs. definitive cohort were 90.2% vs. 66.7%, 82.2% vs 45.4%, and 72.1% vs. 30.3%. Locoregional tumor control in the adjuvant cohort was significantly longer than in the definite cohort (P < 0.005). Distant metastases were diagnosed in 20.4% of all patients. Most patients had mild CTCAE grade 1 and 2 adverse events and mild late adverse events including xerostomia, dysphagia, and lymphedema. CONCLUSION Intensity-modulated radiotherapy for OPC is an important part of the treatment algorithm alone and in particular after surgery while the additional benefits of chemotherapy might be age dependent. Despite advanced tumor stages, nearly half of our patients were alive in the long term. The majority of patients had relatively mild chronic adverse events.

Stroke death in patients receiving radiation for head and neck cancer in the modern era. Front Oncol 2023; 13:1111764. [PMID: 37397363 PMCID: PMC10313411 DOI: 10.3389/fonc.2023.1111764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 05/30/2023] [Indexed: 07/04/2023] Open
Abstract
Objectives Head and neck cancer is a common malignancy frequently treated with chemotherapy and radiotherapy. Studies have shown an increased risk of stroke with the receipt of radiotherapy, but data on stroke-related mortality are limited, particularly in the modern era. Evaluating stroke mortality related to radiotherapy is vital given the curative nature of head and neck cancer treatment and the need to understand the risk of severe stroke in this population. Methods We analyzed the risk of stroke death among 122,362 patients (83,651 patients who received radiation and 38,711 patients who did not) with squamous cell carcinoma of the head and neck (HNSCC) diagnosed between 1973 and 2015 in the SEER database. Patients in radiation vs. no radiation groups were matched using propensity scores. Our primary hypothesis was that radiotherapy would increase the hazard of death from stroke. We also examined other factors impacting the hazard of stroke death, including whether radiotherapy was performed during the modern era when IMRT and modern stroke care were available as well as increased HPV-mediated cancers of the head and neck. We hypothesized that the hazard of stroke death would be less in the modern era. Results There was an increased hazard of stroke-related death in the group receiving radiation therapy (HR 1.203, p = 0.006); however, this was a very small absolute increase, and the cumulative incidence function of stroke death was significantly reduced in the modern era (p < 0.001), cohorts with chemotherapy (p=0.003), males (p=0.002), younger cohorts (p<0.001) and subsites other than nasopharynx (p=0.025). Conclusions While radiotherapy for head and neck cancer increases the hazard of stroke death, this is reduced in the modern era and remains a very small absolute risk.

Weekly versus 3-weekly cisplatin along with radiotherapy for locoregionally advanced non-nasopharyngeal head and neck cancers: Is the equipoise in literature addressed yet? Head Neck 2023; 45:1594-1603.

Abstract
Concurrent chemoradiotherapy with 3-weekly cisplatin 100 mg/m2 has been the standard of care for locoregionally advanced head and neck cancer (LA-HNC) with level I evidence. While the outcomes in terms of efficacy have been well established, the toxicity profile, compliance, and real-world applicability has been an area of ongoing concern for this regimen, leading the oncologists to explore weekly cisplatin chemoradiotherapy regimen to potentially address the issue. A review of literature was conducted in Pubmed, Scopus, and Medline to compare and evaluate the present role of weekly cisplatin chemotherapy along with radiotherapy versus 3-weekly cisplatin chemotherapy along with radiotherapy in both adjuvant and definitive settings for locoregionally advanced head and neck cancers. Nasopharyngeal subsites were excluded from the literature review and 50 relevant articles were included in the analysis. Recently published evidences of noninferiority of weekly over 3-weekly cisplatin chemoradiotherapy regimen in definitive as well as adjuvant settings in locoregionally advanced head and neck cancers is highlighted and interpreted. Results supporting and against the above in different publications is elaborated in this article. Trials designed to demonstrate noninferiority of the weekly cisplatin chemoradiotherapy regimen over 3-weekly regimen, especially in definitive setting may conclude the debate in future. A lacunae in the existing literature is noted in the form of lack of superiority trials on the above topic, which may impact future conclusions.

Abstract
Radiotherapy and chemotherapy are integral parts of definitive and adjuvant therapy in the treatment of head and neck squamous cell carcinoma (HNSCC). The outcome of therapy is essentially dependent on selection and dosage of chemotherapeutical substances and on the other hand on the radiotherapeutical setting concerning fractionation, time of therapy and technical aspects. Immunotherapeutical substances have an increasing role in the therapy of HNSCC as well as particle therapy is investigated as part of radiotherapy in actual studies. Further challenges relate to treatment of HPV-induced tumors with regard to their differences in tumor biology and consecutively better prognosis.

Abstract
BACKGROUND/AIM Some patients with unresectable or incompletely resected head-and-neck cancer (SCCHN) cannot tolerate radiochemotherapy. Alternatives are needed that are more effective than conventional radiotherapy alone. PATIENTS AND METHODS This retrospective study investigated patients irradiated for non-metastatic stage IV SCCHN who could not receive concurrent chemotherapy. Eight patients received accelerated radiotherapy with concomitant boost (group A) and 31 patients conventionally fractionated radiotherapy (group B). Groups were matched for tumor site, gender, age, performance score and histologic grade. RESULTS Two-year PFS-rates were 63% in group A vs. 41% in group B, and median PFS-times were 36 vs. 10 months (p=0.48). Two-year OS-rates were 88% vs. 37%, and median OS-times were 44 vs. 14 months (p=0.19). Grade ≥2 radiation dermatitis was significantly (p=0.040) more common in group B; other toxicities were similar. CONCLUSION Accelerated fractionation with concomitant boost appeared superior to conventional fractionation and can be considered for patients with stage IV SCCHN not suitable for radiochemotherapy. Larger studies are needed to confirm these findings.

Ultrasound-mediated cavitation enhances the delivery of an EGFR-targeting liposomal formulation designed for chemo-radionuclide therapy. Theranostics 2019; 9:5595-5609.

Abstract
Nanomedicines allow active targeting of cancer for diagnostic and therapeutic applications through incorporation of multiple functional components. Frequently, however, clinical translation is hindered by poor intratumoural delivery and distribution. The application of physical stimuli to promote tumour uptake is a viable route to overcome this limitation. In this study, ultrasound-mediated cavitation of microbubbles was investigated as a mean of enhancing the delivery of a liposome designed for chemo-radionuclide therapy targeted to EGFR overexpressing cancer. Method: Liposomes (111In-EGF-LP-Dox) were prepared by encapsulation of doxorubicin (Dox) and surface functionalisation with Indium-111 tagged epidermal growth factor. Human breast cancer cell lines with high and low EGFR expression (MDA-MB-468 and MCF7 respectively) were used to study selectivity of liposomal uptake, subcellular localisation of drug payload, cytotoxicity and DNA damage. Liposome extravasation following ultrasound-induced cavitation of microbubbles (SonoVue®) was studied using a tissue-mimicking phantom. In vivo stability, pharmacokinetic profile and biodistribution were evaluated following intravenous administration of 111In-labelled, EGF-functionalised liposomes to mice bearing subcutaneous MDA-MB-468 xenografts. Finally, the influence of ultrasound-mediated cavitation on the delivery of liposomes into tumours was studied. Results: Liposomes were loaded efficiently with Dox, surface decorated with 111In-EGF and showed selective uptake in MDA-MB-468 cells compared to MCF7. Following binding to EGFR, Dox was released into the intracellular space and 111In-EGF shuttled to the cell nucleus. DNA damage and cell kill were higher in MDA-MB-468 than MCF7 cells. Moreover, Dox and 111In were shown to have an additive cytotoxic effect in MDA-MB-468 cells. US-mediated cavitation increased the extravasation of liposomes in an in vitro gel phantom model. In vivo, the application of ultrasound with microbubbles increased tumour uptake by 66% (p<0.05) despite poor vascularisation of MDA-MB-468 xenografts (as shown by DCE-MRI). Conclusion:111In-EGF-LP-Dox designed for concurrent chemo-radionuclide therapy showed specificity for and cytotoxicity towards EGFR-overexpressing cancer cells. Delivery to tumours was enhanced by the use of ultrasound-mediated cavitation indicating that this approach has the potential to deliver cytotoxic levels of therapeutic radionuclide to solid tumours.

Abstract
AbstractAimWeekly low-dose cisplatin is routinely used in concurrent chemoradiation (CCRT) in locally advanced head and neck cancer (LAHNC), despite 3-weekly cisplatin being the standard of care. We compared compliance, toxicity and efficacy in weekly versus 3-weekly cisplatin CCRT in LAHNC.Materials and methodsIn this retrospective study, weekly cisplatin 50 mg flat dose was compared with 3-weekly cisplatin 100 mg/m2, when given in CCRT in LAHNC with curative intent. The study outcome was compliance, toxicity, loco-regional control (LRC), disease-free survival (DFS) and overall survival (OS).ResultsEighty-four patients received CCRT from January 2013 to June 2017, 40 in weekly and 44 in 3-weekly arm. There was no difference between the arms not completing scheduled radiation therapy or chemotherapy. Patient receiving 200 mg/m2 cisplatin is higher in 3-weekly arm compared with weekly arm (75 versus 40·9%; p<0·0015). Compared with 3-weekly arm, more patient in weekly arm developed grade ≥3 mucositis (52·5 versus 15·9%, p=0·0004), day care intravenous hydration (82·5 versus 38·6% <0·0001) and in-patient admission (55·0 versus 18·2%; p=0·0004). The 2-year LRC, DFS and OS in weekly versus 3-weekly arm were: 70 versus 61·4% (p=0·406); 67·5 versus 56·8% (p=0·314); 67·5 versus 61·4% (p=0·558), respectively. The median time to LRR, DFs and OS was not reached.ConclusionsWeekly cisplatin is comparable with 3-weekly cisplatin in terms of compliance, disease control and survival, but with increased grade 3 mucositis and higher admissions for supportive care.

Abstract
RNA interference (RNAi) therapy is an emerging class of biopharmaceutical that has immense potential in cancer medicine. RNAi medicines are based on synthetic oligonucleotides that can suppress a target protein in tumour cells with high specificity. This review explores the attractive prospect of using RNAi as a radiosensitiser by targeting the DNA damage response. There are a multitude of molecular targets involved in the detection and repair of DNA damage that are suitable for this purpose. Recent developments in delivery technologies such nanoparticle carriers and conjugation strategies have allowed RNAi therapeutics to enter clinical trials in the treatment of cancer. With further progress, RNAi targeting of the DNA damage response may hold great promise in guiding radiation oncology into the era of precision medicine.

Abstract
Introduction: The competing (noncancer) deaths have increased with aggressive treatment approach and better disease control in locally advanced head-and-neck cancer. Aim: The aim of this study is to find incidence, cause and predictors of early competing mortality in locally advanced head-and-neck cancer patients undergoing combined modality therapy. Subjects and Methods: In this retrospective study, a total of 125 locally advanced head-and-neck patients treated from January 2013 to June 2017 were analyzed. The total number of deaths, cause, and the time of death from the start of therapy was recorded. To study the risk factors of competing deaths, univariate and multivariate logistic regression was applied. Data were analyzed using SPSS v. 24 software. Results: A total of 51 deaths (31 cancer deaths and 20 competing deaths) recorded at a median follow-up of 16 months (1–62 months). The incidence of early competing mortality was 12% (n = 15) with a median time of 2.7 months from treatment initiation. Sepsis was major cause of early competing death (n = 13). On univariate and multivariate logistic regression analysis, competing death was significantly associated with pharyngeal (oropharynx, hypopharynx, and larynx) site primary (odds ratio [OR] = 3.562; 95% confidential interval [CI] = 1.207–10.517; P = 0.016), and Stage IVA/IVB disease (OR = 5.104; 95% CI = 1.123–23.202; P = 0.021). Conclusion: Competing deaths is one of the multifaceted problems in locally advanced head-and-neck cancer patients. Sepsis being single most cause of early competing deaths in Stage IVA/IVB pharyngeal and laryngeal cancer.

Abstract
Objectives A Bayesian network meta-analysis (NMA) was conducted in patients with head and neck cancers (HNCs) to estimate the efficacy and safety of treatment with conventional fractionation radiotherapy (CF), conventional fractionation chemoradiotherapy (CF_CRT), hyperfractionated radiotherapy (HF), hyperfractionated chemoradiotherapy (HF_CRT), accelerated fractionation radiotherapy, accelerated fractionation chemoradiotherapy, accelerated hyperfractionated radiotherapy (HART) or accelerated hyperfractionated chemoradiotherapy (HACRT) to identify superior treatments to aid in clinical decisions. Methods PubMed, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for potentially eligible randomized controlled trials up to December 2016. Overall survival (OS), disease-free survival (DFS) and locoregional control (LRC) were considered efficacy outcomes, whereas acute toxicity and late toxicity on skin and mucosa were considered safety outcomes. The surface under the cumulative ranking curve (SUCRA) was calculated to rank each treatment in each index. Results Data from 72 trials with 21,868 participants were included in the analysis. Concerning OS, all treatments were associated with a significant advantage compared to CF alone, with HR effect sizes ranging from 0.64 to 0.83, and HACRT was significantly more effective than all the other treatments. The network comparisons of both HACRT vs HART and HF_CRT vs HF demonstrated a higher OS benefit, with an HR of 0.78 (95% credible interval [CrI]: 0.64–0.95) and 0.78 (95% CrI: 0.61–0.99), respectively. The results of SUCRA indicated that HACRT had the best ranking for OS and LRC, HF_CRT for DFS, HART for acute and late skin toxicity, CF_CRT for acute mucosal toxicity and HF_CRT for late mucosal toxicity. Conclusion The NMA results support the notion that HACRT is the preferable treatment modality for HNCs because it has better rankings in all three efficacy indexes, although it does present a high risk of acute mucosal toxicity.

Abstract
BACKGROUND Surprisingly little is known about the burden of oral mucositis (OM). We provide a systematic review of studies on the burden of OM (incidence, economic impact, health-related quality of life (HRQoL)). METHODS Systematic literature searches were made in BIOSIS, EMBASE, and MEDLINE. Inclusion criteria were studies on OM in hematology/oncology patients of ≥ 18 years, journal articles, English language, and published between 2000 and 2016; OM treatment studies were excluded. Quality assessment was performed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS We screened 4,996 hits, and identified 68 studies of which 13 were without transparency on OM grading. The evidence level of 65 studies was rated 'low' or 'very low' in 58.5%, 'moderate' in 20% and 'high' in 21.5%. Mean value of incidence (7 studies) was 83.5% for all grades of OM with hematopoietic stem cell transplantation. OM incidence for all grades in head and neck cancer patients was 59.4-100%. Considering the economic impact, 16 studies showed highly variable numbers. HRQoL was measured in 16 studies using 13 different instruments. Statistically significant changes in HRQoL scores were demonstrated. CONCLUSION OM is common, burdensome, costly and imposes major reductions in HRQoL. However, from a quality standpoint, the level of current evidence in OM is disappointing. The field needs continued attention to address methodological challenges.

Radiotherapy for locally advanced resectable T3-T4 laryngeal cancer-does laryngeal preservation strategy compromise survival? JOURNAL OF RADIATION RESEARCH 2018; 59:77-90.

Abstract
With the advancement of chemotherapy, a laryngeal preservation (LP) strategy was explored with the aim of improving maintenance of quality of life. Induction chemotherapy (ICT) following radiotherapy (RT) was considered a viable option because of its high initial response rate without hampering of overall survival (OS). Subsequently, concurrent chemoradiotherapy (CCRT) using CDDP became the standard of care for LP, showing the best LP ratio. For enhancing treatment intensity, ICT with taxan + CDDP + 5-FU (TPF-ICT) followed by RT showed superiority over ICT with CDDP + 5-FU (PF-ICT) followed by RT. Given that almost all randomized controlled trials investigating ICT include not only operable (endpoint, LP) but also inoperable (endpoint, OS) cases, physicians are faced with a dilemma regarding application in daily practice. In addition, increased treatment intensity causes augmentation of adverse events, which might reduce compliance. Thereafter, cetuximab, an effective drug with fewer adverse effects [bioradiotherapy (BRT)], emerged as another option. However, little evidence has confirmed its superiority over RT (or CCRT) in laryngeal cancer subpopulations. In spite of these developments, the OS of patients with laryngeal cancer has not improved for several decades. In fact, several studies indicated a decrease in OS during the 1990s, probably due to overuse of CCRT. Fortunately, the latter was not the case in most institutions. Currently, no other treatment has better OS than surgery. The eligibility criteria for LP and/or surgery largely depend upon the available expertise and experience, which differ from one institution to another. Therefore, a multidisciplinary team is required for the treatment of LP.

Abstract
OBJECTIVES Altered fractionation radiotherapy and concomitant chemoradiotherapy represent commonly used intensification strategies in the management of locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). This meta-analysis compares compliance, safety, and efficacy between two single-agent cisplatin schedules given concurrently with altered fractionation radiotherapy. METHODS We systematically searched for prospective trials of patients with LA-SCCHN who received post-operative or definitive altered fractionation concurrent chemoradiotherapy. High-dose cisplatin once every three to four weeks (100 mg/m2, 2 doses) was compared with a weekly low-dose protocol (≤50 mg/m2, ≥4 doses). The primary outcome was overall survival. The secondary endpoints comprised treatment adherence, acute and late toxicities, and objective response rate. RESULTS Twelve studies with 1373 patients treated with definitive chemoradiotherapy were included. Compared to the weekly low-dose cisplatin regimen, the three- to four-weekly high-dose cisplatin regimen improved overall survival (p=.0185), was more compliant with respect to receiving all planned cycles of cisplatin (71% versus 95%, p=.0353), and demonstrated less complications in terms of severe (grade 3-4) acute mucositis and/or stomatitis (75% versus 40%, p=.0202) and constipation (8% versus 1%, p=.0066), toxic deaths (4%, versus 1%, p=.0168), 30-day mortality (8% versus 3%, p=.0154), and severe late subcutaneous fibrosis (21% versus 2%, p<.0001). Overall and complete response rates were similar between both chemotherapy schedules. CONCLUSION In chemoradiotherapy incorporating altered fractionation, two cycles of high-dose cisplatin with a three to four week interval are superior to weekly low-dose schedules. Further studies should identify those who might derive the greatest benefit from this intensified approach.

JOURNAL OF RADIATION RESEARCH 2017; 58:495-508.

Abstract
Early laryngeal, especially glottic, cancer is a good candidate for radiotherapy because obvious early symptoms (e.g. hoarseness) make earlier treatment possible and with highly successful localized control. This type of cancer is also a good model for exploring the basic principles of radiation oncology and several key findings (e.g. dose, fractionation, field size, patient fixation, and overall treatment time) have been noted. For example, unintended poor outcomes have been reported during transition from 60Cobalt to linear accelerator installation in the 1960s, with usage of higher energy photons causing poor dose distribution. In addition, shell fixation made precise dose delivery possible, but simultaneously elevated toxicity if a larger treatment field was necessary. Of particular interest to the radiation therapy community was altered fractionation gain as a way to improve local tumor control and survival rate. Unfortunately, this interest ceased with advancements in chemotherapeutic agents because alternate fractionation could not improve outcomes in chemoradiotherapy settings. At present, no form of acceleration can potentially compensate fully for the lack of concurrent chemotherapy. In addition, the substantial workload associated with this technique made it difficult to add extra fractionation routinely in busy clinical hospitals. Hypofractionation, on the other hand, uses a larger single fractionation dose (2-3 Gy), making it a reasonable and attractive option for T1-T2 early glottic cancer because it can improve local control without the additional workload. Recently, Japan Clinical Oncology Group study 0701 reprised its role in early T1-T2 glottic cancer research, demonstrating that this strategy could be an optional standard therapy. Herein, we review radiotherapy history from 60Cobalt to modern linear accelerator, with special focus on the role of alternate fractionation.

Abstract
PURPOSE OF REVIEW Management of advanced head and neck cancer (HNC) is characterized by high mortality. Furthermore, the treatment involves significant burden to patients and high costs to healthcare systems. Recognizing the risks of early death in patients with a high probability of noncurable disease is important for each individual treatment decision-making. It is thus critical to consider the benefits and side-effects of the planned treatment in relation to the expected survival and to discuss these factors with the patient. However, only few studies have documented early death in HNC patients, that is, during the first posttreatment 6 months. We performed a systematic literature review to find the incidence of this phenomenon and to outline the probable cause. RECENT FINDINGS Early mortality in patients with HNC can be explained either by direct effect of malignant disease, may be related to comorbidities, or secondary to the treatment. These factors act together resulting in expected or unexpected early death. SUMMARY The present review provides information on the mechanisms leading to early phase mortality (<6 months) after management of HNC. It also reports the incidence of this phenomenon among Finnish and Swedish patient populations.
