[PMID: 39118899 PMCID: PMC11303669 DOI: 10.1007/s12663-023-01963-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Accepted: 06/19/2023] [Indexed: 08/10/2024] Open
Abstract
Aim The present review article aims to compile the best available evidence-based data on oral metronomic chemotherapy (OMCT) including its mechanism of action, its utility, and future directions. Methods A systematic search was carried out in PubMed database for available English literature from last 10 years between 2011 and 2021. Keyword combinations used were 'Oral Metronomic chemotherapy for oral cancer, mechanism of action of OMCT, Oral metronomic chemotherapy in India, OMCT in recurrent and palliative treatment of oral cancers.' Results Multitudes of studies have been published recently stating the role of OMCT in head and neck squamous cell carcinoma (HNSCC), but the studies with the category of level of evidence required to advocate OMCT as a recognized therapy are still scarce. On careful stratification of these studies, we found that OMCT has a lot to offer in palliative settings, recurrent, and metastatic HNSCC. There is some limited evidence of its role in adjuvant therapy as maintenance and in neoadjuvant setting. Conclusion With current evidence, there is a definite role of OMCT in treatment of oral SCC. OMCT can be an alternative in patients who are not tolerable or affordable for standard palliative chemotherapy and also an option for patient who are waiting for surgery. However, results of ongoing and future studies on exact mechanism, indications, and implications of this drug regimen would help in integration OMCT in current standard of therapy. Graphical abstract

J Dent Sci 2024; 19:1486-1498. [PMID: 39035282 PMCID: PMC11259733 DOI: 10.1016/j.jds.2024.02.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 02/16/2024] [Indexed: 07/23/2024] Open
Abstract
Background/purpose Explorations of novel regimens enhancing efficacy and selectivity of chemotherapeutic agents are urgent to solve the problems of cancer therapy. This study aimed to explore synergistic anticancer effects of novel regimens of phytopolyphenols [curcumin (C), tea polyphenols (G) or GC] with celecoxib (Cl) and ZnSO4. Materials and methods Antiproliferative effects of drugs on cultured cancer cells and pathogenic biofilms were assayed by MTT and optical density (OD600) respectively; their inhibition on efflux pump (Na+-K+-ATPase) was measured by colorimetric methods. Synergistic (CI < 1) anticancer effects were evaluated by the equations of combination index (CI) and efficacy index (EI). Results Both Cl and methotrexate (MTX) alone exhibited inhibitory effects not only on proliferation and efflux pump of cultured cancer cells but also pathogenic biofilm formation. Phytopolyphenols (P) and MTX potentiated these inhibitory effects of Cl. In addition, novel regimens containing Cl, memantine (Mem) or thioridazine (TRZ) further enhanced not only efficacy and selectivity of anticancer effects but also inhibition on efflux pump and pathogenic biofilm formation of four chemotherapeutic agents (MTX, cisplatin, 5-fluorouracil and doxorubicin) respectively. Conclusion In this study, novel regimens of phytopolyphenols (P), targeting drugs (T; Cl, Mem or TRZ) and metal ions (M; ZnSO4) so called PTM regimens exerted not only by themselves but also markedly potentiated efficacy and selectivity of anticancer effects of four chemotherapeutic agents. Because of their potent inhibitions on efflux pump and pathogenic biofilm formation, these combinatorial novel regimens were expected to be able to overcome the problems of multidrug resistant cancers and merit for further clinical studies.

Abstract
Metronomic chemotherapy (mCHEMO), based on frequent, regular administration of low, but pharmacologically active drug doses, optimizes antitumor efficacy by targeting multiple targets and reducing toxicity of antineoplastic drugs. This minireview will summarize preclinical and clinical studies on cytotoxic drugs given at weekly, daily, or at continuous metronomic schedules alone or in combination with novel targeted agents for hematological malignancies, including lymphoma, multiple myeloma, and leukemia. Most of the preclinical in vitro and in vivo studies have reported a significant benefit of both mCHEMO monotherapy and combinatorial regimens compared with chemotherapy at the maximum tolerated dose. However, the combination of mCHEMO with targeted drugs is still little explored in the hematologic clinical setting. Data obtained from preclinical studies on low dose metronomic chemotherapy in hematological malignancies clearly suggested the possibility to clinically investigate more tolerable and effective strategies for the treatment of patients with advanced hematological malignancies, or at least for those frail and elderly patients, who are not eligible or resistant to standard treatments.

Abstract
Metronomic chemotherapy (MCT), characterized by the continuous administration of chemotherapeutics at a lower dose without prolonged drug-free periods, has garnered significant attention over the last 2 decades. Extensive evidence from both pre-clinical and clinical settings indicates that MCT induces distinct biological effects than the standard Maximum Tolerated Dose (MTD) chemotherapy. The low toxicity profile, reduced likelihood of inducing acquired therapeutic resistance, and low cost of MCT render it an attractive chemotherapeutic regimen option. One of the most prominent aspects of MCT is its anti-angiogenesis effects. It has been shown to stimulate the expression of anti-angiogenic molecules, thereby inhibiting angiogenesis. In addition, MCT has been shown to decrease the regulatory T-cell population and promote anti-tumor immune response through inducing dendritic cell maturation and increasing the number of cytotoxic T-cells. Combination therapies utilizing MCT along with oncolytic virotherapy, radiotherapy or other chemotherapeutic regimens have been studied extensively. This review provides an overview of the current status of MCT research and the established mechanisms of action of MCT treatment and also offers insights into potential avenues of development for MCT in the future.

Abstract
The use of conventional chemotherapy in conjunction with targeted and immunotherapy drugs has emerged as an option to limit the severity of side effects in patients diagnosed with head and neck cancer (HNC), particularly oropharyngeal cancer (OPC). OPC prevalence has increased exponentially in the past 30 years due to the prevalence of human papillomavirus (HPV) infection. This study reports a comprehensive review of clinical trials registered in public databases and reported in the literature (PubMed/Medline, Scopus, and ISI web of science databases). Of the 55 clinical trials identified, the majority (83.3%) were conducted after 2015, of which 77.7% were performed in the United States alone. Eight drugs have been approved by the FDA for HNC, including both generic and commercial forms: bleomycin sulfate, cetuximab (Erbitux), docetaxel (Taxotere), hydroxyurea (Hydrea), pembrolizumab (Keytruda), loqtorzi (Toripalimab-tpzi), methotrexate sodium (Trexall), and nivolumab (Opdivo). The most common drugs to treat HPV-associated OPC under these clinical trials and implemented as well for HPV-negative HNC include cisplatin, nivolumab, cetuximab, paclitaxel, pembrolizumab, 5-fluorouracil, and docetaxel. Few studies have highlighted the necessity for new drugs specifically tailored to patients with HPV-associated OPC, where molecular mechanisms and clinical prognosis are distinct from HPV-negative tumors. In this context, we identified most mutated genes found in HPV-associated OPC that can represent potential targets for drug development. These include TP53, PIK3CA, PTEN, NOTCH1, RB1, FAT1, FBXW7, HRAS, KRAS, and CDKN2A.

Abstract
BACKGROUND There is a concern that terminally ill cancer patients may be aggressively treated due to the rapidly growing possibilities of anticancer treatment. The aim of this study was to evaluate the use of anticancer treatment at the end of life (EoL). MATERIALS AND METHODS This retrospective study included adult patients with advanced solid cancers who were treated at the Institute of Oncology Ljubljana and died of cancer between January 2015 and December 2019. A multiple logistic regression model was used to assess an association between the aggressiveness of anticancer treatment (i.e. systemic therapy, radiotherapy and surgery) in the last 2 weeks of life and year of death, age at death, sex, prognosis of cancer and enrolment into the specialist palliative care (SPC). RESULTS We included 1736 patients in our analysis. Overall, 13.7% of patients were enrolled into the SPC and 14.4% received anticancer treatment in the last 2 weeks of life. The odds of receiving anticancer treatment significantly increased over time [odds ratio (OR) 1.15, 95% confidence interval (CI) 1.04-1.27]. There was an increased use of novel systemic therapy (e.g. small-molecule targeted therapy and immunotherapy) at the EoL. Older patients had significantly lower odds to receive anticancer treatment in the last 2 weeks of life as compared to younger patients (OR 0.96, 95% CI 0.95-0.98). As compared to patients receiving only a standard oncology care, those also enrolled into the SPC had significantly lower odds for anticancer treatment in the last 2 weeks of life (OR 0.22, 95% CI 0.12-0.43). CONCLUSIONS Terminally ill cancer patients have increased odds for receiving anticancer treatment, especially novel systemic therapies, in the last 2 weeks of life. Younger patients and those not enrolled into the SPC are at particular risk for anticancer treatment at the EoL.

Abstract
Cancer represents a significant global health and economic burden due to its high mortality rates. While effective in some instances, traditional chemotherapy often falls short of entirely eradicating various types of cancer. It can cause severe side effects due to harm to healthy cells. Two therapeutic approaches have risen to the forefront to address these limitations: metronomic chemotherapy (MCT) and drug repurposing. Metronomic chemotherapy is an innovative approach that breaks from traditional models. It involves the administration of chemotherapeutic regimens at lower doses, without long drug-free intervals that have previously been a hallmark of such treatments. This method offers a significant reduction in side effects and improved disease management. Simultaneously, drug repurposing has gained considerable attraction in cancer treatment. This approach involves utilizing existing drugs, initially developed for other therapeutic purposes, as potential cancer treatments. The application of known drugs in a new context accelerates the timeline from laboratory to patient due to pre-existing safety and dosage data. The intersection of these two strategies gives rise to a novel therapeutic approach named 'Metronomics.' This approach encapsulates the benefits of both MCT and drug repurposing, leading to reduced toxicity, potential for oral administration, improved patient quality of life, accelerated clinical implementation, and enhanced affordability. Numerous clinical studies have endorsed the efficacy of metronomic chemotherapy with tolerable side effects, underlining the potential of Metronomics in better cancer management, particularly in low- and middle-income countries. This review underscores the benefits and applications of metronomic chemotherapy and drug repurposing, specifically in the context of breast cancer, showcasing the promising results of pre-clinical and clinical studies. However, we acknowledge the necessity of additional clinical investigations to definitively establish the role of metronomic chemotherapy in conjunction with other treatments in comprehensive cancer management.

Abstract
OBJECTIVES The aim of this pilot study is to identify the genetic factors that contribute to the response of metronomic chemotherapy in head and neck squamous cell carcinoma (HNSCC) patients using whole-exome sequencing (WES). This study would facilitate the identification of predictive biomarkers, which would enable personalized treatment strategies and improve treatment outcomes for patients with HNSCC. MATERIALS AND METHODS We have selected patients with recurrent head and neck cancer who underwent metronomic chemotherapy. Sequential tumor biopsies were collected from the patients at different stages of treatment to capture the genomic alterations and tumor evolution during metronomic chemotherapy and sequenced using WES. RESULTS We identified several known HNSCC hallmark genes reported in COSMIC, including KMT2B, NOTCH1, FAT1, TP53, HRAS, CASP8, and CDKN2A. Copy number alteration analysis revealed amplifications and deletions in several oncogenic and tumor suppressor genes. COSMIC Mutational Signature 15 associated with defective DNA mismatch repair was enriched in 73% of HNSCC samples. Further, the comparison of genomic alterations between responders and non-responders identified HRAS gene uniquely mutated in non-responders that could potentially contribute to resistance against metronomic chemotherapy. DISCUSSION Our findings corroborate the molecular heterogeneity of recurrent HNSCC tumors and establish an association between HRAS mutations and resistance to metronomic chemotherapy, suggesting HRAS as a potential therapeutic target. Combining HRAS inhibitors with metronomic regimens could improve treatment sensitivity in HRAS-mutated HNSCC patients. Further studies are needed to fully elucidate the genomic mechanisms underlying the response to metronomic chemotherapy.

Abstract
INTRODUCTION The outcome of recurrent/metastatic gynaecological malignancy has drastically improved with the introduction of poly(ADP-ribose) polymerase inhibitors and immunotherapy, but the use of these drugs in routine practice is complicated due to access barriers and their high cost in developing countries. The purpose of this study is to present the clinical response, outcome and safety of oral metronomic chemotherapy (OMCT) in resource-limited, financially constrained populations. METHODS This is a retrospective study on patients with advanced gynaecological cancer treated at Chittaranjan National Cancer Institute, Kolkata, India, from 2021 to 2023. The patients were treated with one of these two regimens: a split-dose course of cyclophosphamide (50 mg orally once daily for 21 days) and capecitabine (500 mg twice daily continuous) or a fixed-dose combination (capecitabine 1800 mg and cyclophosphamide 80 mg orally for 14 days in every 21 days) until disease progression or unacceptable toxicities occurred. All data was captured from the hospital's medical records until June 2023. Toxicity data was reported per the Common Terminology Criteria for Adverse Events (CTCAE) v5.1, and progression-free survival (PFS) was estimated using Kaplan-Meier methods. RESULTS Among 34 screened patients, 10 were excluded due to noncompliance. This study analysed 24 patients with a median age at diagnosis of 56 years (IQ range 44-75). Sixteen (67%) patients were at stage IV disease with an Eastern Cooperative Oncology Group (ECOG) performance status of 3. Ovarian and cervical cancers were 80% and 20%, respectively; among them, 16 (67%) patients were platinum-refractory. Forty-two per cent of patients received three lines of chemotherapy before OMCT. A split course versus fixed dose was given to 67% versus 33% of the population; the best responses per the Response Evaluation Criteria in Solid Tumours v1.1 were complete response in 12%, partial response in 67% and stable disease in 21%. The most common toxicities were grade I anaemia (54%), grade I chemotherapy-induced nausea and vomiting (46%), grade I fatigue (42%) and grade I neutropenia (21%). Twenty-five per cent of patients were offered next-line systemic therapy after progression. The entire cohort had a median PFS of nine months (95%, CI: 5.2-12.7). Cox regression analysis identified a median PFS of 12 months (95%, CI: 6.2-17.7) among platinum-refractory groups. CONCLUSION OMCT was a well-tolerated, affordable regimen with durable clinical response and survival outcome (median PFS of nine months) in recurrent, refractory advanced gynaecological cancer and can be offered to patients at resource-limited centres.

Abstract
Pantoprazole decreases the acidity of the tumor microenvironment by inhibiting proton pumps on the cancer cell. This possibly leads to increased sensitivity to cytotoxic therapy. We conducted a phase I/II randomized controlled trial in adult patients with head and neck squamous cell carcinoma (HNSCC) planned for first-line palliative chemotherapy. Patients were randomized to chemotherapy + / - intravenous (IV) pantoprazole. The primary endpoint in phase I was to determine the maximum safe dose of intravenous pantoprazole, whereas it was progression-free survival (PFS) in phase II. The dose of IV pantoprazole established in phase I was 240 mg. Between Nov'18 and Oct'20, we recruited 120 patients in phase II, 59 on pantoprazole and 61 on the standard arm. Median age was 51 years (IQR 43-60), 80% were men. Systemic therapy was IV cisplatin in 22% and oral-metronomic-chemotherapy (OMC) in 78%. Addition of pantoprazole did not prolong PFS, which was 2.2 months (95% CI 2.07-3.19) in the pantoprazole arm and 2.5 months (95% CI 2.04-3.81, HR, 1.14; 95% CI 0.78-1.66; P = 0.48) in the standard arm. Response rates were similar; pantoprazole arm 8.5%, standard arm 6.6%; P = 0.175. Overall survival was also similar; 5.6 months (95% CI 4.47-8.51) in the pantoprazole arm and 5.4 months (95% CI 3.48-8.54, HR 1.06; 95% CI 0.72-1.57; P = 0.75) in the standard arm. Grade ≥ 3 toxicities were similar. Thus, pantoprazole 240 mg IV added to systemic therapy does not improve outcomes in patients with advanced HNSCC.

Abstract
Treatment of locally advanced oral cancer requires multidisciplinary care, including surgery, radiotherapy, and chemotherapy, which varies based on the stage of the disease, site of involvement, and surgical access. Oral cancer usually presents with an increased recurrence rate and potential for distant metastatic spread. It confers a poor prognosis with a 50% mortality rate after five years. Oral metronomic chemotherapy aims to achieve higher patient compliance due to its ease of administration, lower dosage, and lesser side effects than conventional IV regimens of platinum-based drugs. In this review, we have summarized the relevant literature to benefit the readers regarding the potential application of metronomic therapy in the management of oral cancer.

Abstract
CircRNAs are a class of endogenous long non-coding RNAs with a single-stranded circular structure. Most circRNAs are relatively stable, highly conserved, and specifically expressed in tissue during the cell and developmental stages. Many circRNAs have been discovered in OSCC. OSCC is one of the most severe and frequent forms of head and neck cancer today, with a poor prognosis and low overall survival rate. Due to its prevalence, OSCC is a global health concern, characterized by genetic and epigenomic changes. However, the mechanism remains vague. With the advancement of biotechnology, a large number of circRNAs have been discovered in mammalian cells. CircRNAs are dysregulated in OSCC tissues and thus associated with the clinicopathological characteristics and prognosis of OSCC patients. Research studies have demonstrated that circRNAs can serve as biomarkers for OSCC diagnosis and treatment. Here, we summarized the properties, functions, and biogenesis of circRNAs, focusing on the progress of current research on circRNAs in OSCC.

Abstract
Background Triple metronomic chemotherapy is one of the options of treatment in platinum-refractory/early failure oral cancer. However, long term outcomes with this regimen are unknown. Methods Adult patients with platinum-refractory/early-failure oral cancer were enrolled in the study. Patients were administered triple metronomic chemotherapy ie erlotinib 150 mg once daily celecoxib 200 mg twice daily and methotrexate weekly (phase 1 in variable dose 15-6 mg/m2 & 9 mg/m2 in phase 2), all taken orally till progression of disease or development of intolerable adverse events. The primary objective was to estimate the long-term overall survival and factors impacting it. The Kaplan Meier method was used for time-to-event analysis. Cox proportional hazard model was used to identify factors impacting overall survival (OS) and progression-free survival (PFS). The factors included in the model were age, sex, Eastern Cooperative Oncology Group - performance status (ECOG PS), tobacco exposure and a subsite of primary and circulating endothelial cell levels at baseline. A p-value of 0.05 was considered significant. Clinical trials information: CTRI/2016/04/006834. Results A total of 91 patients were recruited (15 in phase 1 & 76 in phase 2), the median follow-up was 41 months and 84 events of death had occurred. The median OS was 6.7 months (95% CI 5.4-7.4). The 1-year, 2-years and 3-year OS' were 14.1% (95% CI 7.8-22.2), 5.9% (95% CI 2.2-12.2) and 5.9% (95% CI 2.2-12.2) respectively. The only factor favorably impacting OS was the detection of circulating endothelial cells at baseline (HR = 0.46; 95% CI 0.28-0.75, P = 0.0020). The median PFS was 4.3 months (95% CI 4.1-5.1) and the 1-year PFS was 13.0% (95% CI 6.8-21.2). The factors with statistically significant impact on PFS were detection of circulating endothelial cells at baseline (HR = 0.48; 95% CI 0.30-0.78, P = 0.0020) and no tobacco exposure at baseline (HR = 0.51; 95% CI 0.27-0.94, P = 0.030). Interpretation The long-term outcomes with triple oral metronomic chemotherapy ie erlotinib, methotrexate and celecoxib are unsatisfactory. Detection of circulating endothelial cells at baseline is a biomarker predicting efficacy of this therapy. Funding The study was funded by an intramural grant from Tata Memorial Center Research Administration Council (TRAC) and Terry Fox foundation.

Abstract
Background Locally advanced head and neck cancers treated with radical chemoradiation have unsatisfactory outcomes. Oral metronomic chemotherapy improves outcomes in comparison to maximum tolerated dose chemotherapy in the palliative setting. Limited evidence suggests that it may do so in an adjuvant setting. Hence this randomized study was conducted. Methods Patients of head and neck (HN) cancer with primary in oropharynx, larynx or hypopharynx, with PS 0-2 post radical chemoradiation with documented complete response were randomized 1:1 to either observation or oral metronomic adjuvant chemotherapy (MAC) for 18 months. MAC consisted of weekly oral methotrexate (15 mg/m2) and celecoxib (200 mg PO BD). The primary endpoint was OS and the overall sample size was 1038. The study had 3 planned interim analyses for efficacy and futility. Trial registration- Clinical Trials Registry- India (CTRI): CTRI/2016/09/007315 [Registered on: 28/09/2016] Trial Registered Prospectively. Findings 137 patients were recruited and an interim analysis was done. The 3 year PFS was 68.7% (95% CI 55.1-79.0) versus 60.8% (95% CI 47.9-71.4) in the observation and metronomic arm respectively (P value = 0.230). The hazard ratio was 1.42 (95% CI 0.80-2.51; P value = 0.231). The 3 year OS was 79.4% (95% CI 66.3-87.9) versus 62.4% (95% CI 49.5-72.8) in the observation and metronomic arm respectively (P value = 0.047). The hazard ratio was 1.83 (95% CI 1.0-3.36; P value = 0.051). Interpretation In this phase 3 randomized study, oral metronomic combinations of weekly methotrexate and daily celecoxib failed to improve the PFS or OS. Hence observation post-complete response post radical chemoradiation remains the standard of care. Funding ICON funded this study.

Abstract
Head and neck squamous cell carcinoma (HNSCC) arises from the interplay of multiple factors, such as smoking, alcohol consumption, and viral infections. Cisplatin-based concurrent radiotherapy regimens represent the first-line treatment for advanced HNSCC cases. However, cisplatin resistance significantly contributes to poor prognoses in HNSCC patients, making it crucial to unravel the underlying mechanisms to overcome this resistance. The complexity of cisplatin resistance in HNSCC involves cancer stem cells, autophagy, epithelial-mesenchymal transition, drug efflux, and metabolic reprogramming. Recent advances in nanodrug delivery systems, combined with existing small-molecule inhibitors and innovative genetic technologies, have opened new therapeutic avenues for addressing cisplatin resistance in HNSCC. This review systematically summarizes research progress from the past five years on cisplatin resistance in HNSCC, with a particular focus on the roles of cancer stem cells and autophagy. Additionally, potential future treatment strategies to overcome cisplatin resistance are discussed, including the targeting of cancer stem cells or autophagy through nanoparticle-based drug delivery systems. Furthermore, the review highlights the prospects and challenges associated with nanodelivery platforms in addressing cisplatin resistance in HNSCC.

Abstract
Metronomic chemotherapy is defined as a high-frequency low-dose schedule of chemotherapy drug administration. Although metronomic chemotherapy is widely used, the mechanisms underlying resistance to metronomic chemotherapy remain unclear. Therefore, we herein conducted a single institutional phase I/II trial to assess the efficacy and safety of metronomic chemotherapy with bleomycin plus S-1, an oral 5-FU prodrug, in the neoadjuvant setting for patients with oral squamous cell carcinoma (OSCC). The response rate of well-differentiated OSCC to metronomic chemotherapy was significantly lower. We investigated differences in molecular profiles between poorly or moderately differentiated head and neck squamous cell carcinoma (HNSCC) and well-differentiated HNSCC from patients with HNSCC TCGA data. EphA4 expression positively correlated with histological differentiation. An upstream regulator analysis correlated with EphA4 expression identified pathways associated with decreased mTORC1 signaling and T cell activation, including TCR, CD3, CD28, and CD40LG. An EphA4 blocking peptide (KYL) induced mTOR activation in well-differentiated OSCC cell lines. Plasmacytoid dendritic cell and CD8+ T cell numbers were higher in the microenvironment of poorly or moderately differentiated HNSCC than in that of well-differentiated HNSCC. Well-differentiated HNSCC had the characteristics of "cold tumors" (immune-excluded tumors). Moreover, KYL used with chemotherapeutic drugs synergistically increased cancer cell death. Well-differentiated OSCC is depleted of immune cells, which may be partly explained by the receptor tyrosine kinase EphA4.

Surgical Treatment for Advanced Oropharyngeal Cancer: A Narrative Review. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020304. [PMID: 36837506 PMCID: PMC9961866 DOI: 10.3390/medicina59020304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 12/30/2022] [Accepted: 01/30/2023] [Indexed: 02/10/2023]
Abstract
Background and Objectives: to describe current scientific knowledge regarding the treatment options in advanced oropharyngeal cancer. The standard care for advanced oropharyngeal cancer (OPSCC) has been chemoradiotherapy, although surgical approaches followed by adjuvant treatment have been proposed. The best therapy for each patient should be decided by an interdisciplinary tumour-board. Different strategies should be considered for the specific patient's treatment: surgery, chemotherapy and radiation therapy or combinations of them. The treatment choice is influenced by tumour variability and prognostic factors, but it also depends on cancer extension, extranodal extension, nervous invasion, human papilloma virus (HPV) presence, making the decisional algorithm not always clear. HPV-related OPSCC is strongly associated with a favourable overall survival (OS) and disease-free survival rate (DSS); by contrast, HPV-negative OPSCC often flags a worse prognosis. Consequently, the American Joint Committee on Cancer (AJCC) differentiates OPSCC treatment and prognosis based on HPV status. Methods: we carried out a review of current scientific literature to analyze the different indications and limitations of surgical treatment options in OPSCC stage III and IV. Conclusion: robotic surgery or open approaches with reconstructive flaps can be considered in advanced stages, resulting in the de-intensification of subsequent systemic therapy and fewer related side effects. Furthermore, in the event of the primary failure of systemic therapy or disease recurrence, the surgical approach constitutes an additional therapeutic option which lengthens patient survival functions.

Abstract
PURPOSE The regimens approved for the treatment of advanced head and neck squamous cell carcinoma are accessible to only 1%-3% of patients in low- and middle-income countries because of their cost. In our previous study, metronomic chemotherapy improved survival in this setting. Retrospective data suggest that a low dose of nivolumab may be efficacious. Hence, we aimed to assess whether the addition of low-dose nivolumab to triple metronomic chemotherapy (TMC) improved overall survival (OS). METHODS This was a randomized phase III superiority study. Adult patients with recurrent or newly diagnosed advanced head and neck squamous cell carcinoma being treated with palliative intent with an Eastern Cooperative Oncology Group performance status of 0-1 were eligible. Patients were randomly assigned 1:1 to TMC consisting of oral methotrexate 9 mg/m2 once a week, celecoxib 200 mg twice daily, and erlotinib 150 mg once daily, or TMC with intravenous nivolumab (TMC-I) 20 mg flat dose once every 3 weeks. The primary end point was 1-year OS. RESULTS One hundred fifty-one patients were randomly assigned, 75 in TMC and 76 in the TMC-I arm. The addition of low-dose nivolumab led to an improvement in the 1-year OS from 16.3% (95% CI, 8.0 to 27.4) to 43.4% (95% CI, 30.8 to 55.3; hazard ratio, 0.545; 95% CI, 0.362 to 0.820; P = .0036). The median OS in TMC and TMC-I arms was 6.7 months (95% CI, 5.8 to 8.1) and 10.1 months (95% CI, 7.4 to 12.6), respectively (P = .0052). The rate of grade 3 and above adverse events was 50% and 46.1% in TMC and TMC-I arms, respectively (P = .744). CONCLUSION To our knowledge, this is the first-ever randomized study to demonstrate that the addition of low-dose nivolumab to metronomic chemotherapy improved OS and is an alternative standard of care for those who cannot access full-dose checkpoint inhibitors.

Abstract
Anaplastic thyroid carcinoma (ATC) is a rare thyroid malignancy with a dire prognosis, nearly 100% disease specific mortality and a median overall survival less than 6 months. In view of the limited data from India on anaplastic thyroid cancer, we conducted this audit to analyze the treatment pattern, outcomes and factors influencing it. This is a retrospective analysis of outcomes of patients treated in a single institution between January 2008 and December 2020. Baseline characteristics, treatment received, and outcomes among adult patients with ATC were collected. Progression free survival (PFS) and overall survival (OS) were analyzed. SPSS version 20 and RStudio version 3.1.1 were used for analysis. In this cohort of 134 patients, the median age at diagnosis was 59 years, with 63.4% of them being females. At presentation, 70.9% of them had good performance status (PS 0-1). Only 38.8% received treatment with curative intent (either surgery fb adjuvant or neoadjuvant chemotherapy fb surgery and adjuvant or definitive chemoradiotherapy) while 61.2% patients received palliative treatment (either palliation alone or palliative chemotherapy or palliative surgery or palliative RT). Predominant pattern of progression was local progression (79.8%). Median PFS and OS of the overall cohort were 58 days and 80 days respectively. PFS and OS were significantly better in patients treated with curative intent vs palliative intent (116 and 134 days vs 45 and 50 days; p = 0.00 and 0.00 respectively). Among patients treated with curative intent, OS was significantly better in patients undergoing surgery vs CTRT (155 vs 76 days; p = 0.03). Among patients treated with upfront surgery, both PFS and OS were better with the addition of adjuvant CTRT/RT vs no adjuvant (332 and 540 days vs 55 and 91 days; p = 0.00 and 0.003 respectively). ATC is a rare cancer with dismal prognosis. Local therapy with surgery followed adjuvant seems to be associated with the better outcomes. Systemic therapy seems to be a better option for palliation. Our data reflects the real world data of this rare cancer.

Abstract
OBJECTIVES The prognosis, choice of reconstruction and the quality of life (QOL) after salvage surgery (SS) for extensively locoregional recurrent/metastatic head and neck cancer (R/M HNC) is an important issue, but there are few reports at present. MATERIALS AND METHODS We analyzed extensively locoregional R/M HNC patients from March 1, 2015, to December 31, 2021 who underwent SS with latissimus dorsi or pectoralis major musculocutaneous flaps. QOL were accessed using QLQ-H&N35 and UW-QOL questionnaire. Wilcoxon signed-rank test was used to compare difference between pre- and post-QOL and Kaplan-Meier curves were used in estimate overall survival (OS) and disease-free survival (DFS). The literature review summarized recent 10 years clinical trials of nonoperative treatment in R/M head and neck cancer. RESULTS 1362 patients were identified and 25 patients were analyzed after screened. Median age at surgery was 59 years (range 43-77), 15/25(60%) were male and 22/25(88%) chose latissimus dorsi flap. Better mean pain score after applying massive soft tissue flaps revealed relief of severe pain(p<0.001) which strongly associated with improvement of QOL. The improved mean overall QOL score after surgery revealed a better QOL(p<0.001). As of June 1, 2022, 11/25 (44%) of the patients were alive. The 1-year, 2-year OS after SS was 58.4% and 37.2%, while the 1-year, 2-year DFS was 26.2% and 20.9%. The median OS of our study was better than nonoperative treatment of 11 included clinical trials. CONCLUSIONS R/M HNC patients underwent SS can obtain survival benefit. The application of massive soft tissue flap in SS could significantly enhance the QOL for patients with extensively locoregional R/M HNC, especially by relieving severe pain.

Abstract
BACKGROUND Improving outcomes in locally advanced esophageal/GEJ squamous cell cancer (SCC) is an unmet need. We investigated the addition of oral metronomic chemotherapy (OMC) following definitive chemoradiotherapy (CRT). MATERIALS AND METHODS This was a randomized open-label integrated phase II/III study in patients with SCC of esophagus/GEJ following definitive CRT who had no radiologic evidence of progression, and no endoscopically detected disease. Randomization was 1:1 to OMC (celecoxib 200 mg twice daily and methotrexate 15 mg/m2 weekly) for 12 months or observation. The primary endpoint for the phase II portion was progression-free survival (PFS); secondary endpoints were overall survival (OS) and toxicity. P ≤ 0.2 for PFS was required to proceed to phase III. RESULTS Between Jan 2016 and Dec 2019, we enrolled 151 patients for the phase II portion, 75 to OMC and 76 to observation. The tumor originated in the upper thoracic esophagus in 79% patients. Concurrent CRT consisted of median 63 Gy in a median of 35 fractions; concurrent chemotherapy was weekly paclitaxel + carboplatin in 91%. OMC was started at a median of 2.6 months (IQR 2.3-2.8) from CRT completion. Grade 3 or higher toxicities occurred in 18 patients (24%) in the OMC arm and 9 (12%) in the observation arm; P = 0.071. Median PFS was 25 months (95% CI, 17-58) in the OMC arm and was not attained [NA] (95% CI, 25-NA) in the observation arm; HR, 1.51, 95% CI, 1-2; P = 0.073. Median OS was 36 months (95% CI, 23-NA) in the OMC arm, and not attained (95% CI, NA-NA) in the observation arm; HR, 1.77; 95% CI, 1-2.9; P = 0.023. CONCLUSION Oral metronomic methotrexate and celecoxib in patients who have not progressed radiologically and have no endoscopic evidence of disease following radical CRT for locally advanced esophageal/GEJ SCC does not improve outcomes and may lower survival.

Abstract
Metastatic castration-resistant prostate cancer (mCRPC) is the ultimately lethal form of prostate cancer. Docetaxel chemotherapy was the first life-prolonging treatment for mCRPC; however, the standard maximally tolerated dose (MTD) docetaxel regimen is often not considered for patients with mCRPC who are older and/or frail due to its toxicity. Low-dose metronomic chemotherapy (LDMC) is the frequent administration of typically oral and off-patent chemotherapeutics at low doses, which is associated with a superior safety profile and higher tolerability than MTD chemotherapy. We conducted a systematic literature review using the PUBMED, EMBASE, and MEDLINE electronic databases to identify clinical studies that examined the impact of LDMC on patients with advanced prostate cancer. The search identified 30 reports that retrospectively or prospectively investigated LDMC, 29 of which focused on mCRPC. Cyclophosphamide was the most commonly used agent integrated into 27/30 (90%) of LDMC regimens. LDMC resulted in a clinical benefit rate of 56.8 ± 24.5% across all studies. Overall, there were only a few non-hematological grade 3 or 4 adverse events reported. As such, LDMC is a well-tolerated treatment option for patients with mCRPC, including those who are older and frail. Furthermore, LDMC is considered more affordable than conventional mCRPC therapies. However, prospective phase III trials are needed to further characterize the efficacy and safety of LDMC in mCRPC before its use in practice.

Abstract
The administration of approved systemic treatments for advanced hepatocellular carcinoma (HCC) is limited to patients with preserved liver function (Child-Pugh A/B7) and performance status. Conversely, metronomic chemotherapy can be safely administered to patients with poor clinical conditions and severe liver impairment. The metronomic schedule demonstrated to exert different anticancer mechanisms compared to that of the same agent administered at its standard schedule, including immune stimulation and the inhibition of angiogenesis and vasculogenesis. Nevertheless, metronomic chemotherapy is a nearly neglected option for the treatment of advanced HCC patients, even among those who cannot afford standard treatments. Herein, we report the case of a 40-year-old patient affected by HBV-HDV-related cirrhosis who was diagnosed with advanced HCC. The severe liver impairment (Child-Pugh B9) did not allow to administer first-line treatment with tyrosine kinase inhibitors so that the patient received metronomic capecitabine as upfront therapy. Due to the suspect of progressive disease at the first radiologic assessment, metronomic cyclophosphamide was added to capecitabine aiming to enhance its efficacy. After 4 months of treatment, complete tumor response, alpha-fetoprotein (AFP) normalization and the recovery of a Child-Pugh A were achieved. The patient was then able to undergo liver transplantation, and, after 18 months from the diagnosis, he is still free of disease recurrence. This experience emphasizes the reliability of metronomic capecitabine as a well-tolerated and effective treatment when patient's conditions prevent the administration of standard first-line treatments. In fact, metronomic capecitabine demonstrated its effectiveness in advanced HCC in retrospective and prospective analyses, leading to median progression-free survival and overall survival of, respectively, 6.03 and 14.47 months in phase II single-arm trial. Moreover, in consideration of the raising interest in immune-checkpoint inhibition in HCC, we believe that the immunomodulating effects of metronomic chemotherapy, either capecitabine or cyclophosphamide, warrant future trials exploring its combination with immunotherapy.

Metronomic chemotherapy regimens and targeted therapies in non-Hodgkin lymphoma: The best of two worlds. Cancer Lett 2022; 524:144-150. [PMID: 34673128 DOI: 10.1016/j.canlet.2021.10.018] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 10/11/2021] [Accepted: 10/13/2021] [Indexed: 12/31/2022]
Abstract
Novel drugs are rapidly moving forward the treatment-paradigm of non-Hodgkin-lymphomas (NHLs). Notwithstanding, especially in aggressive subtypes, chemotherapy remains the pillar of treatment. Indeed, the combination of highly effective Maximum-Tolerated-Dose Chemotherapy (MTD-CHEMO) + "novel drugs", has so far, fallen short from expectations, often because it caused excessive toxicity. Metronomic chemotherapy (mCHEMO), which is the frequent, long-term administration of low dose cytotoxic drugs, may allow more effective and tolerable combinations. mCHEMO pharmacodynamics, has been described as pleiotropic. In fact, it may have different cellular and molecular targets, when drugs or their schedules are modified. Although mCHEMO has been little explored in NHLs, pre-clinical studies - in lymphoma models - which addressed the activity of mCHEMO in combination with novel drugs, have shown very promising results. These included inhibitors of histone deacetylase, mTOR and PI3K/mTOR, as well as the immune checkpoint inhibitor anti-PD-L1. Moreover, a few impressive reports have recently shown all-oral mCHEMO schedules, with or without rituximab, can effectively shrink both B and T-cell aggressive NHLs. Indeed, these regimens allowed elderly-frail patients to achieve sustained remission, while toxicity proved manageable. In our opinion, all-oral mCHEMO, is an active, easy-to start, well-tolerated, and inexpensive therapeutic approach, which deserves further investigation. Most importantly, mCHEMO, holds promise to empower the activity of novel targeted therapies, without causing excessive toxicity.

Abstract
In the era of rapid development of new, expensive cancer therapies, value frameworks have been developed to quantify clinical benefit (CB). We assessed the evolution of CB since the 2015 introduction of The American Society of Clinical Oncology and The European Society of Medical Oncology value frameworks. Randomized clinical trials (RCTs) assessing systemic therapies for solid malignancies from 2010 to 2020 were evaluated and CB (Δ) in 2010–2014 (pre-value frameworks (PRE)) were compared to 2015–2020 (POST) for overall survival (OS), progression-free survival (PFS), response rate (RR), and quality of life (QoL). In the 485 studies analyzed (12% PRE and 88% POST), the most common primary endpoint was PFS (49%), followed by OS (20%), RR (12%), and QoL (6%), with a significant increase in OS and decrease in RR as primary endpoints in the POST era (p = 0.011). Multivariable analyses revealed significant improvement in ΔOS POST (OR 2.86, 95% CI 0.46 to 5.26, p = 0.02) while controlling for other variables. After the development of value frameworks, median ΔOS improved minimally. The impact of value frameworks has yet to be fully realized in RCTs. Efforts to include endpoints shown to impact value, such as QoL, into clinical trials are warranted.

Abstract
BACKGROUND In an era of targeted therapies, patients with cancer in resource-constraint countries continue to struggle to find affordable care. METHODS The present study is a multicenter prospective single-arm study. Patients with expected delay in surgery, unresectable or metastatic cancers, and patients not suitable for surgery or conventional chemotherapy were included. Oral methotrexate 15 mg/m2 once a week and oral celecoxib 200 mg twice daily was used for metronomic therapy. RESULTS At 8 weeks, a clinically complete response was seen in 2.5%, partial response in 46.6%, stable disease in 39.8%, and disease progression in 11%. Size less than 4 cm, alveolobuccal subsite, and well-differentiated histology were significantly associated with no disease progression. CONCLUSION Constraint-adapted approach of using methotrexate and celecoxib is economical with good compliance, minimal toxicity, and good efficacy. It is feasible for use in diverse settings. Individualized selection of patients based on response predictors may maximize metronomic therapy's benefit.

Abstract
Oral squamous cell carcinoma (OSCC), the eighth most prevalent cancer in the world, arises from the interaction of multiple factors including tobacco, alcohol consumption, and betel quid. Chemotherapeutic agents such as cisplatin, 5-fluorouracil, and paclitaxel have now become the first-line options for OSCC patients. Nevertheless, most OSCC patients eventually acquire drug resistance, leading to poor prognosis. With the discovery and identification of non-coding RNAs (ncRNAs), the functions of dysregulated ncRNAs in OSCC development and drug resistance are gradually being widely recognized. The mechanisms of drug resistance of OSCC are intricate and involve drug efflux, epithelial-mesenchymal transition, DNA damage repair, and autophagy. At present, strategies to explore the reversal of drug resistance of OSCC need to be urgently developed. Nano-delivery and self-cellular drug delivery platforms are considered as effective strategies to overcome drug resistance due to their tumor targeting, controlled release, and consistent pharmacokinetic profiles. In particular, the combined application of new technologies (including CRISPR systems) opened up new horizons for the treatment of drug resistance of OSCC. Hence, this review explored emerging regulatory functions of ncRNAs in drug resistance of OSCC, elucidated multiple ncRNA-meditated mechanisms of drug resistance of OSCC, and discussed the potential value of drug delivery platforms using nanoparticles and self-cells as carriers in drug resistance of OSCC.

Abstract
BACKGROUND Early palliative care (EPC) is an important aspect of cancer management but, to our knowledge, has never been evaluated in patients with head and neck cancer. Hence, we performed this study to determine whether the addition of EPC to standard therapy leads to an improvement in the quality of life (QOL), decrease in symptom burden, and improvement in overall survival. METHODS Adult patients with squamous cell carcinoma of the head and neck region planned for palliative systemic therapy were allocated 1:1 to either standard systemic therapy without or with comprehensive EPC service referral. Patients were administered the revised Edmonton Symptom Assessment Scale and the Functional Assessment of Cancer Therapy for head and neck cancer (FACT-H&N) questionnaire at baseline and every 1 month thereafter for 3 months. The primary endpoint was a change in the QOL measured at 3 months after random assignment. All statistical tests were 2-sided. RESULTS Ninety patients were randomly assigned to each arm. There was no statistical difference in the change in the FACT-H&N total score (P = .94), FACT-H&N Trial Outcome Index (P = .95), FACT-general total (P = .84), and Edmonton Symptom Assessment Scale scores at 3 months between the 2 arms. The median overall survival was similar between the 2 arms (hazard ratio for death = 1.01, 95% confidence interval = 0.74 to 1.35). There were 5 in-hospital deaths in both arms (5.6% for both, P = .99). CONCLUSIONS In this phase III study, the integration of EPC in head and neck cancer patients did not lead to an improvement in the QOL or survival.

Abstract
There are several controversies in the management of head and neck cancer (SCCHN). Although combined modality treatment is standard in locally advanced SCCHN (LA-SCCHN), the optimal timing of chemotherapy has been debated. Toxicity concerns with chemoradiation (CRT) using high dose cisplatin have prompted use of less intensive approaches. Weekly cisplatin and targeted therapies have been explored in randomized trials. Benefit of neoadjuvant chemotherapy in LA-SCCHN is debated due to lack of impact on overall survival, however, it remains a viable option in the Indian setting where many patients are not eligible for upfront surgery or definite CRT due to advanced stage and poor performance status (PS). The complexity of data of immune check point inhibitors (ICPi) in metastatic setting needs cautious interpretation till an ideal biomarker for their benefit is identified. Their significant cost and promising data of oral metronomic therapy has made the treatment landscape of metastatic SCCHN even more complex. To address these burning issues, we did a critical review of evidence of systemic therapy in SCCHN.

Abstract
Introduction: Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers worldwide and is a leading cause for cancer-related mortality. This review attempts to give a comprehensive summary of the recent developments in pharmacotherapeutic options for locally advanced/metastatic HNSCC.Areas covered: In this review, the authors conducted a systematic literature search for published articles on HNSCC in the PubMed database using the keywords 'head and neck squamous cell carcinoma or HNSCC,' 'targeted therapy,' 'immunotherapy.' The search was restricted to meta-analyses, clinical trials, practice guidelines, and abstract presentations at international meetings. The final search encompassed articles published from 2010 to 2021. Articles published in languages other than English were excluded.Expert opinion: Immune checkpoint inhibition has been the most significant advance in the treatment of R/M HNSCC. Oral metronomic therapy has emerged as an important therapeutic option for low to middle-income countries. H-RAS inhibition is one of the most promising areas of research.

Abstract
Metronomic therapy is characterized by drug administration in a low-dose, repeated, and regular manner without prolonged drug-free interval. The two main anticancer mechanisms of metronomic therapy are antiangiogenesis and immunomodulation, which have been demonstrated in several delicate in vitro and in vivo experiments. In contrast to the traditional maximum tolerated dose (MTD) dosing of chemotherapy, metronomic therapy possesses comparative efficacy but greatlydecreases the incidence and severity of treatment side-effects. Clinical trials of metronomic anticancer treatment have revealed promising results in a variety cancer types and specific patient populations such as the elderly and pediatric malignancies. Oral cavity squamous cell carcinoma (OCSCC) is an important health issue in many areas around the world. Long-term survival is about 50% in locally advanced disease despite having high-intensity treatment combined surgery, radiotherapy, and chemotherapy. In this article, we review and summarize the essence of metronomic therapy and focus on its applications in OCSCC treatment.

Abstract
Simple Summary The present article reviews the state of the art of metronomic chemotherapy use to treat the principal types of cancers, namely breast, non-small cell lung cancer and colorectal ones, and of the most recent progresses in understanding the underlying mechanisms of action. Areas of novelty, in terms of new regimens, new types of cancer suitable for Metronomic chemotherapy (mCHT) and the overview of current ongoing trials, along with a critical review of them, are also provided. Abstract Metronomic chemotherapy treatment (mCHT) refers to the chronic administration of low doses chemotherapy that can sustain prolonged, and active plasma levels of drugs, producing favorable tolerability and it is a new promising therapeutic approach in solid and in hematologic tumors. mCHT has not only a direct effect on tumor cells, but also an action on cell microenvironment, by inhibiting tumor angiogenesis, or promoting immune response and for these reasons can be considered a multi-target therapy itself. Here we review the state of the art of mCHT use in some classical tumour types, such as breast and no small cell lung cancer (NSCLC), see what is new regarding most recent data in different cancer types, such as glioblastoma (GBL) and acute myeloid leukemia (AML), and new drugs with potential metronomic administration. Finally, a look at the strategic use of mCHT in the context of health emergencies, or in low –and middle-income countries (LMICs), where access to adequate healthcare is often not easy, is mandatory, as we always need to bear in in mind that equity in care must be a compulsory part of our medical work and research.

Abstract
The overwhelming majority of head and neck cancers and related deaths occur in low- and middle-income countries, which have challenges related to burden of disease versus access to care. Yet the additional health care burden of the COVID-19 pandemic has also impacted access to care for patients with head and neck cancer in the United States. This article focuses on challenges and innovation in prioritizing head and neck cancer care in Sub-Saharan Africa, the Indian experience of value-added head and neck cancer care in busy and densely populated regions, and strategies to optimize the management of head and neck cancer in the United States during the COVID-19 pandemic.

The Overall Efficacy and Outcomes of Metronomic Tegafur-Uracil Chemotherapy on Locally Advanced Head and Neck Squamous Cell Carcinoma: A Real-World Cohort Experience. BIOLOGY 2021; 10:biology10020168. [PMID: 33672266 PMCID: PMC7926982 DOI: 10.3390/biology10020168] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 02/10/2021] [Accepted: 02/19/2021] [Indexed: 12/24/2022]
Abstract
Simple Summary In head and neck squamous cell carcinoma (HNSCC), more than 60% of patients presenting with locally advanced disease carries a high risk of recurrence and distant metastasis, with a poor prognosis (five-year overall survival (OS), <50%). Therefore, further prevention of recurrence and distant metastasis is crucial for survival improvement in advanced HNSCC patients. In this retrospective study, we investigated the outcomes of metronomic chemotherapy with tegafur–uracil in locally advanced HNSCC (LA HNSCC). Our data showed that adding tegafur–uracil after curative surgery with adjuvant chemoradiotherapy or definitive concurrent chemoradiotherapy significantly improved OS, DFS, and DMFS in patients with LA HNSCC. As a metronomic maintenance regimen, tegafur–uracil was well tolerated with minimal adverse effects. We suggested tegafur–uracil as a maintenance therapy of choice for patients with LA HNSCC. Abstract Metronomic chemotherapy inhibits tumor growth by continuous administration of lower-dose chemotherapy. Our study aimed to demonstrate the outcomes of metronomic chemotherapy with tegafur–uracil in locally advanced head and neck squamous cell carcinoma (LA HNSCC). This was a retrospective study including 240 patients with LA HNSCC. After standard treatment, 96 patients were further treated with metronomic tegafur-uracil, and 144 patients were not. No statistical differences were found between both groups with regard to sex, clinical stage, or primary treatment choice. There were more hypopharyngeal cancers and more patients with poor clinicopathological features, including lymphovascular invasion, extranodal extension, and positive margins in the tegafur–uracil group. The median follow-up duration was 31.16 months. Overall survival (OS) was not reached in the tegafur–uracil group and was 54.1 months in the control group (p = 0.008). The median disease-free survival (DFS) was 54.5 months in the tegafur–uracil group and 34.4 months in the control group (p = 0.03). Neither group reached distant metastasis-free survival (DMFS, p = 0.02). In patients with LA HNSCC, adding tegafur–uracil as metronomic chemotherapy after either curative surgery with adjuvant chemoradiotherapy or definitive concurrent chemoradiotherapy significantly improved the OS, DFS, and DMFS with tolerable adverse events.
