Triple combination of palliative oral metronomic chemotherapy in recurrent and metastatic epithelial ovarian cancer: A retrospective study

Background: Ovarian cancer is a leading cause of death from gynecological cancer in the world and in India. This study aims to evaluate the efficacy and toxicity profile of oral metronomic chemotherapy (MCT) in the form of etoposide, cyclophosphamide, and tamoxifen in recurrent and metastatic ovarian cancer. Methods: This was a retrospective observational study that included those post?treatment patients who had the recurrent or metastatic disease after completion of treatment in 2018 at Regional Cancer Centre, Bikaner, Rajasthan. Forty patients who were unfit for further intensive intravenous chemotherapy were included. The oral MCT constituted etoposide, cyclophosphamide, and tamoxifen. Descriptive statistics and Kaplan?Meier analyses were performed. Progression?free survival (PFS) and overall survival (OS) were assessed. Results: Forty women with a median age of 62 (range: 35?80) years were enrolled in the study to receive oral MCT. The Eastern Cooperative Oncology Group?Performance Status (ECOG?PS) was 0�in 28 patients and 2�in 12 patients. The best clinical response rate post?oral MCT was seen in the first 4 months. Objective response was observed in 24 (60%) of patients in the form of stable disease (19, 47.5%) and partial response (5, 12.5%). Disease progression was observed in 10 (25%) of patients. The median follow?up was 6.4 months (4.5�2 months). The median estimated OS was 6.5 months. The median estimated PFS was 3.7 months. Nineteen (47.5%) patients had grade?I/II mucositis. Grade?III/IV mucositis were observed in 9 (22.5%) patients. Thirty?seven (92.5%) patients died at the end of the study at 1 year. Dose reduction was required in 15 (37.5%) patients. Conclusion: Oral MCT was found to be an effective and well?tolerated regime with good symptomatic control and low?moderate toxicity profile in patients with relapsed and metastatic ovarian cancer. However, 22% of patients showed grade?III/IV thrombocytopenia.

The mechanisms underlying metronomic chemotherapy and its application in advanced non-small cell lung cancer / 中华老年医学杂志

The morbidity and mortality of non-small cell lung cancer(NSCLC)are among the highest of all malignancies.The mechanisms concerning metronomic chemotherapy include anti-angiogenesis, immune microenvironment regulation, and cytotoxic effects, among others.As an alternative to traditional chemotherapy, metronomic chemotherapy has shown promising outcomes in the treatment of advanced NSCLC.Several clinical trials have explored the application of metronomic chemotherapy in the treatment of advanced NSCLC, either as a monotherapy or in combination with chemotherapy, anti-angiogenic therapy, targeted therapy or immunotherapy.This paper mainly reviews the mechanisms underlying metronomic chemotherapy and its clinical application in advanced NSCLC, in order to provide more evidence for the optimization of NSCLC treatment regimens.

Comparison between hematological and biochemical changes caused by conventional and metronomic chemotherapies in the treatment of canine transmissible venereal tumor / Comparação entre as alterações hematológicas e bioquímicas ocasionadas pela quimioterapia convencional e quimioterapia metronômica no tratamento do tumor venéreo transmissível canino

This study aimed to report the hematological and biochemical changes caused by conventional and metronomic chemotherapies, using vincristine sulfate to treat canine Transmissible Venereal Tumor (TVT). Twelve dogs were selected, six of them for the group receiving conventional chemotherapy (G1), and six dogs for the group receiving metronomic chemotherapy (G2). The G1 group received vincristine sulfate once a week at the dose of 0.75mg/m² until the tumor had disappeared with treatment, and the G2 group was treated with vincristine sulfate three times a week at the dose of 0.25mg/m2 until the tumor had disappeared. Before and after chemotherapy treatment, hematological and biochemical blood tests were performed to evaluate the main alterations caused by both chemotherapeutic models. Dogs undergoing conventional chemotherapy had significant leukocyte changes (p<0.05), causing neutropenia and leukopenia. In dogs undergoing metronomic chemotherapy, leukocytes remained within the reference range. Half of the dogs in group G1 had normochromic, normocytic anemia. The only biochemical alteration observed was the increase of urea in group G2. Thus, metronomic chemotherapy for the treatment of TVT with vincristine sulfate proved to be an excellent method for treatment, with fewer adverse effects, especially in maintaining the leukogram of dogs within normal range and reducing the number of anemia in animals during treatment.(AU)

Esta pesquisa teve como objetivo relatar as alterações hematológicas e bioquímicas causadas pelo tratamento quimioterápico convencional e pela quimioterapia metronômica, utilizando-se sulfato de vincristina para o tratamento do tumor venéreo transmissível canino(TVTC). Foram selecionados 12 cães, sendo seis para o grupo que recebeu quimioterapia convencional (G1) e seis cães para o grupo que recebeu quimioterapia metronômica (G2). O grupo G1 recebeu sulfato de vincristina, uma vez por semana, na dose de 0,75mg/m2, até o desaparecimento do tumor e o grupo G2 foi tratado com sulfato de vincristina, três vezes por semana, na dose de 0,25mg/m2, até o desaparecimento do tumor. Antes e após o tratamento quimioterápico foram realizados exames hematológicos e bioquímicos sanguíneos para avaliação das principais alterações causadas pelos dois modelos quimioterápicos. Os cães submetidos à quimioterapia convencional tiveram alterações leucocitárias significativas (p<0,05), causando uma leucopenia por neutropenia enquanto nos cães, submetidos à quimioterapia metronômica, os leucócitos mantiveram-se dentro do intervalo de referência. A metade dos cães do grupo G1 tiveram uma anemia do tipo normocítica normocrômica. A única alteração bioquímica observada foi o aumento da ureia no grupo G2. Desta forma, a quimioterapia metronômica para o tratamento do TVT com sulfato de vincristina, demonstrou ser um excelente método para a cura do animal, com menores reduções de efeitos adversos, sobretudo, na manutenção do leucograma dos cães e na redução de animais com anemia.(AU)

Metronomic palliative chemotherapy in locally advanced, recurrent and metastatic head-and-neck cancer: A single-arm, retrospective study of a regional cancer center of North India (Asia)

Background: Head-and-neck cancer is the most common cancer in developing countries of Southeast Asia. Most of the patients present to the hospital in advanced stage and have a poor prognosis. This study aims to evaluate the efficacy and toxicity profile of oral metronomic chemotherapy (MCT) in the form of methotrexate and celecoxib in locally advanced, recurrent and metastatic head-and-neck cancers. Materials and Methods: This was a single-arm retrospective observational study that included posttreatment patients with locally advanced, recurrent and metastatic disease in the year 2016 (January 1, to December 31, 2016). A total of 84 patients warranting palliative chemotherapy but not willing to take intravenous chemotherapy were included in the study. The oral MCT schedule consisted of oral celecoxib (200 mg twice daily) and oral methotrexate (15 mg/m2/week). Response evaluation was done using the Response Evaluation Criteria in Solid Tumors criteria version 1.1, and toxicity profile was assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03. Descriptive statistics and Kaplan–Meier analysis were performed. Results: Eighty-four patients, 68 males and 16 females, with a median age of 62 years (range: 35–80 years), were enrolled in the study to receive oral MCT. The Eastern Cooperative Oncology Group performance status was 0–1 in 62 patients and 2–3 in 22 patients. The primary sites of disease were buccal mucosa (18), tongue (22), tonsil (24), lower alveolus (7), hypopharynx (10), and soft palate (3). The best clinical response rate in post oral MCT was seen in the first 4 months (120 days). Objective response was observed in 67% of patients in the form of stable disease (56%) and partial response (11%). Disease progression was observed in 27% of patients. The median follow-up was 192 (6.4 months) days. The median estimated overall survival was 195 (6.5 months) days. The median estimated progression-free survival was 110 (3.6 months) days. Symptomatic relief with respect to pain was reported in about 75% of patients. Eighteen (21%) patients had Grade I–II mucosal reactions. Grade III–IV mucosal reactions were observed in five (6%) patients. Seventy-eight (93%) patients died at the end of the study at 1 year. Dose reduction was required in 15 (18%) patients. Conclusion: Oral MCT using celecoxib and methotrexate is an effective, economical, and well-tolerated regimen with good pain control and low toxicity profile in patients with locally advanced, recurrent and metastatic head-and-neck cancer.

Quimioterapia metronómica en pacientes con cáncer de mama metastásico / Metronomic chemotherapy in patients with metastatic breast cancer

RESUMEN La quimioterapia metronómica es un tipo de quimioterapia cuya toxicidad es mínima. Consiste en administrar agentes antineoplásicos habituales a intervalos muy próximos uno del otro y a dosis relativamente bajas durante un tiempo prolongado y sin periodos de descanso farmacológico. Esta terapia reduce la toxicidad y elimina la necesidad de tratamientos de soporte, por lo tanto, el empleo de esta modalidad de tratamiento en pacientes con enfermedad metastásica resulta de gran interés. Muchas investigaciones han evaluado la administración de medicamentos antineoplásicos en esquemas metronómicos, tanto en monoterapia como en combinación. Los fármacos mayormente estudiados son la ciclofosfamida, vinorelbina y capecitabina. Diversos estudios han mostrado la eficacia y tolerancia de esta terapia combinada con la hormonoterapia e inmunoterapia. Es necesaria mayor evidencia científica para definir cuestiones como: pacientes que más beneficio puedan obtener y las combinaciones terapéuticas a emplear de acuerdo al tipo de paciente.

ABSTRACT Metronomic chemotherapy is a type of chemotherapy whose toxicity is minimal. It consists of administering usual antineoplastic agents at intervals very close to each other and at relatively low doses for a prolonged time without periods of pharmacological rest. This therapy reduce toxicity and eliminates the need for supportive treatments, therefore, the use of this treatment modality in patients with metastatic disease is of great interest. Many investigations have evaluated the administration of antineoplastic drugs in metronomic schemes, both in monotherapy and in combination. The most studied drugs are cyclophosphamide, vinorelbine and capecitabine. Several studies have shown the efficacy and tolerance of this therapy combined with hormone therapy and immunotherapy. More scientific evidence is needed to define issues such as: patients who can obtain more benefit and the therapeutic combinations to be used according to the type of patients.

Impact of Oral Metronomic Therapy on Quality of Life in Advanced/Recurrent Head and Neck Squamous Cell Carcinoma Patients

Introduction: Metronomic chemotherapy (MC) is an emerging therapeutic option in clinical oncology and it may prove usefulat least in metastatic head and neck squamous cell carcinoma (HNSCC) patients. To develop rational therapeutic strategies,it is important to identify molecular targets that are linked to the pathogenesis of HNSCC.Aim: The aim of the study was to assess the effect of oral MC on changes in quality of life (QOL) in advanced/recurrent HNSCCpatients.Materials and Methods: Patients with advanced, metastatic, and recurrent HNSCC patients who are not amenable to localtreatment with surgery, radiotherapy, and chemotherapy were included in the study. QOL assessed with the European organizationfor research and treatment of cancer (EORTC) QLQ-C30 and QLQ-H&N 35 questionnaires.Results: In this study, 50 patients were included, 37 patients (74%) become pain-free at the end of 6 months. A decreasedpain grade was observed in another 13 patients (26%). Mean QLQ-C 30 score at the time of presentation was 68.67, 75.35at 2 months, 81.26 at 4 months, and 85.38 at the end of 6 months. Mean QLQ-H&N 35 score at the time of presentation was61.53, 72.16 at 2 months, 76.43 at 4 months, and 81.69 at the end of 6 months. In subgroup analysis, both QLQ-C30 andQLQ-H&N 35 significantly correlated with disease progression.Conclusion: The use of oral metronomic therapy with methotrexate and celecoxib significantly improves the QOL and improvespain control in patients with advanced/recurrent HNSCC

Oral metronomic chemotherapy for recurrent & refractory epithelial ovarian cancer: A retrospective analysis

Background & objectives: Advanced epithelial ovarian cancer (EOC) is associated with dismal outcome and progression-free survival (PFS) shortens with each subsequent relapse. For patients with recurrent and platinum refractory disease, therapeutic options are limited. Oral metronomic therapy (OMT) is associated with symptomatic relief and stable response in a significant proportion of patients. We retrospectively evaluated the outcome of patients with EOC treated with OMT at a tertiary care hospital in north India. Methods: Between January 2011 to December 2017, 36 EOC patients received OMT. Patients' median age was 50 yr (range, 38-81 yr) and they had received a median of two lines of prior chemotherapy. OMT regimen included a combination of cyclophosphamide, etoposide (VP-16) and celecoxib with or without pazopanib along with supportive care. Response rates and outcomes were ascertained using the Gynecological Cancer Intergroup Guidelines. The toxicity was graded according to the Common Terminology Criteria for Adverse Events v.4.03. Results: The median CA-125 before initiating OMT was 160 U/ml (range, 42.23-5330 U/ml). The median interval between last chemotherapy and starting OMT regimen was 159 days (range, 1-1211 days). The overall response rate was 50 per cent. The median progression-free survival (PFS) was 8.2 months [95% confidence interval (CI): 5.03-10.33], and the median overall survival was 38 months (95% CI: 25.6-NR). Patients who received two lines of chemotherapy before OMT (P=0.052) and those who received pazopanib-based OMT (P=0.0513) had better PFS. Interpretation & conclusions: For patients with relapse and refractory EOC, OMT could be a reasonable option. A combination of oral etoposide (VP-16) and pazopanib needs further evaluation in a large number of patients in a randomized trial.

​Outcome of Oral Metronomic Therapy with Methotrexate and Celecoxib in Advanced/ Recurrent Head and Neck Squamous Cell Carcinoma

Introduction: Metronomic chemotherapy (MC) is an emerging therapeutic option in clinical oncology and it may prove usefulat least in metastatic HNSCC patients. To develop rational therapeutic strategies, it is important to identify molecular targetsthat are linked to the pathogenesis of HNSCC.Aim: This study aims to assess the efficacy and toxicity of oral MC with methotrexate and celecoxib in the treatment of advanced/recurrent HNSCC.Methods: Patients who received MC for advanced/recurrent HNSCC were analyzed. The combination of weekly oral methotrexate5 mg twice daily for 2 days/week and oral celecoxib 200 mg twice daily was offered as MC. The efficacy was noted in terms ofclinical benefit rate (CBR), pain control, changes in quality of life (QOL), and median time to progression (TTP).Results: A total of 50 patients were included in this study. At the end of 6 months, 4 patients (8%) had partial response (PR), 28patients (56%) had stable disease (SD), and 18 patients (36%) had progressive disease. The CBR (complete response+PR+SD)was 64% at 6 months. The median TTP was 8 weeks. At the end of 6 months, 60% of patients were pain free. The most common(>20% of patients) treatment-related adverse events were nausea (22%), vomiting (22%), and mucositis (20%). 6 patients (12%)developed anorexia and 3 patients (6%) developed fatigue. Mean QOL scores were improved with this MC.Conclusion: Oral MC with methotrexate and celecoxib for patients with advanced/recurrent HNSCC was effective, well tolerated,provides good pain control, and improves QOL with least toxicity profile.

High-dose versus Low-dose 5-Fluorouracil and Cisplatin Based Hepatic Arterial Infusion Chemotherapy for Advanced Hepatocellular Carcinoma

BACKGROUND/AIMS: Hepatic arterial infusion chemotherapy (HAIC) has been reported as an effective treatment for advanced hepatocellular carcinoma. The aim of this study is to compare the effect and safety between a high-dose regimen (750 mg/m2 5-fluorouracil [FU] and 25 mg/m2 cisplatin on day 1–4) and a low-dose regimen (500 mg/m2 5-FU on day 1–3 with 60 mg/m2 cisplatin on day 2). METHODS: A total of 48 patients undergoing HAIC were retrospectively analyzed. Thirty-two patients were treated with the high-dose and 16 patients with the low-dose regimen. RESULTS: Complete response (CR), partial response (PR), stable disease (SD), and progressive disease were noted in one (3.1%), 15 (46.9%), three (9.4%), and 13 patients (40.6%) in the highdose group, and 0 (0%), one (6.3%), eight (50%), and seven patients (43.8%) in the low-dose group (P=0.002). The disease control rate (CR, PR, and SD) did not differ between groups (59.4% vs. 56.3%, P=1.000), but the objective response rate (CR and PR) was significantly higher in the high-dose group (50.0% vs. 6.3%, P=0.003). The median progression free survival did not differ between groups (4.0 vs. 6.0, P=0.734), but overall survival was significantly longer in the high-dose group (not reached vs. 16.0, P=0.028). Fourteen (43.8%) patients in the high-dose group and two patients (12.5%) in the low-dose group experienced grade 3–4 toxicities (P=0.050). CONCLUSIONS: High dose HAIC may achieve better tumor response and may improve overall survival compared to a low-dose regimen. However, the high-dose regimen should be administered cautiously because of the higher incidence of adverse events.

Research progress in metronomic photodynamic therapy / 国际生物医学工程杂志

Metronomic photodynamic therapy (mPDT) is a new type of photodynamic therapy (PDT) that has received much attention in recent years. It has a similar therapeutic mechanism to traditional PDT, i.e. the photosensitizer is irradiated by visible light irradiation with a specific wavelength, and tissue oxygen photochemical reactions produce cytotoxic reactive oxygen species (ROS) that selectively kill rapidly proliferating tumor cells. Unlike traditional PDT, the photosensitizer and light in mPDT are continuously transmitted at a low time and at a low rate, and the specificity of tumor treatment is enhanced by apoptosis. In this paper, the current researches on the in vitro and in vivo effects and mechanisms of mPDT, as well as the research status of photosensitizers and light sources for in vivo research, were reviewed, with a view to understanding the existing mPDT technology and providing reference for the further studies. This review paper can provide a basic for promoting the clinical research and application of mPDT.

An alternative approach with a low dose and prolonged chemotherapy for palliative treatment of locally advanced, metastatic or recurrent squamous cell head and neck cancer

Background: It is expected that about 65,000 new patients will be diagnosed with head and neck cancer in 2017 in the United States. Patients with recurrent or advanced or metastatic head and neck do not have good survival due to aggressive and recurrent nature of this cancer. Moreover, cumulative and residual toxicities from previous and ongoing treatments significantly impede quality of remaining part of their life. Currently available chemotherapeutic regimens for this group are derived from the treatments used for the potentially curable disease. These regimens and associated toxicity are obviously not the best matches for the treatment with palliative intent. We here present a retrospective study where we used dose-adjusted chemotherapy specifically for palliative treatment this sub-group of head and neck cancer patients. Methods: Study population was identified from the University of Florida, and IRB approval was obtained. We used currently available and approved chemotherapeutic agents (including Taxols, Platins, 5-Fluorouracil and Epidermal Growth Factor Receptor inhibitors) for treatment of head and neck cancer but dose-adjusted at approximate 50% dose of currently recommended doses. We then gave personalized doses for a prolonged period by titrating doses based on response and tolerability of each patient. Data was collected for treatment, response, side effects, and outcomes. KM analysis was performed for survival data. Results: Total of 32 patients were included in this study with a median age of 65.2 years and a median follow-up of 10.1 months. 62.5% (n = 20) had locally advanced disease and rest had metastatic disease. 37.5% (n = 12) had new disease while rest had recurrent cancer. Of 32 patients, 14 patients received TPF based while 18 patients received PFE based chemotherapy. Total of 270 chemotherapy cycles were delivered among these 32 patients. They received a median of 9 cycles (range 3­14) over a median of 6.2 months (range 1.8­21.1). With this treatment approach, we noted median progression-free survival of 14.0 months and median overall survival of 15.7 months. Notable grade 3 toxicities were generalized fatigue in 12.5% (n = 4), nausea/vomiting in 6.3% (n = 2), diarrhea in in 6.3% (n = 2), mouth soreness in 6.3% (n = 2), rash in 3.1% (n = 1), neutropenia in 18% (n = 6) and anemia in 15.6% (n = 5) while notable grade 4 toxicities were neutropenia and anaphylaxis in 3.1% (n = 1) patient each (AU)

Rhythmic chemotherapy affects the growth of tumor cells by influencing the formation of blood vessels and the immune system / 实用肿瘤学杂志

Objective The objective of this study was to determine the effect of curative chemotherapy regimen on breast cancer cells and its mechanism.Methods A tumor-bearing mouse model was established and routine dose of capecitabine was given as a conventional chemotherapy group.Continuous low-dose capecitabine chemotherapy was used as a radiotherapy group and no chemotherapy was used as a control group.The expression of microvessel density(MVD),vascular endothelial growth factor(VEGF)and thrombospondin 1(TSP-1)were measured by flow cytometry.The percentage of myeloid-derived suppressor cells(MDSCs),NK cells and macrophages in the program was observed.The tumor size and blood leukocyte count were measured after chemotherapy.Results MVD and VEGF in the radiotherapy group were significantly decreased and TSP-1 was significantly increased in comparison with the conventional chemotherapy group(P0.05).However,the white blood cell count in the radiotherapy group was significantly higher than that in the conventional chemotherapy group(P<0.05).Conclusion Capecitabine chemotherapy at continuous low-dose inhibits neovascularization and adjusts the proportion of immune cells to suppress tumor formation.Thus,this chemotherapy could reduce side effects caused by chemotherapy and improve the quality of life.

A comparative study of sorafenib and metronomic chemotherapy for Barcelona Clinic Liver Cancer-stage C hepatocellular carcinoma with poor liver function

BACKGROUND/AIMS: Metronomic chemotherapy (MET) is frequently administered in comparatively low doses as a continuous chemotherapeutic agent. The aim of this study was to evaluate the feasibility and overall survival (OS) of MET compared to sorafenib for advanced hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT). METHODS: A total of 54 patients with advanced HCC and PVTT who had undergone MET were analyzed between 2005 and 2013. A total of 53 patients who had undergone sorafenib therapy were analyzed as the control group. The primary endpoint of this study was OS. RESULTS: The median number of MET cycles was two (1-15). The OS values for the MET group and sorafenib group were 158 days (132-184) and 117 days (92-142), respectively (P=0.029). The Cox proportional-hazard model showed that a higher risk of death was correlated with higher serum alpha fetoprotein level (≥400 mg/dL, hazard ratio [HR]=1.680, P=0.014) and Child-Pugh class B (HR=1.856, P=0.008). CONCLUSIONS: MET was associated with more favorable outcomes in terms of overall survival than was sorafenib in patients with advanced HCC with PVTT, especially in patients with poor liver function. Therefore, MET can be considered as a treatment option in patients with advanced HCC with PVTT and poor liver function.

Efficacy comparison of capecitabine metronomic chemotherapy and conventional chemotherapy in the maintenance of elderly patients with metastatic breast cancer / 肿瘤研究与临床

Objective To investigate the clinical efficacy of capecitabine metronomic chemotherapy in the maintenance of elderly patients with metastatic breast cancer. Methods Fifty-six patients with metastatic breast cancer treated in Jiangsu Shengze Hospital from April 2014 to April 2017 were randomly divided into two groups according to random number table method: metronomic chemotherapy group (n = 28) and conventional chemotherapy group (n = 28). The patients in the metronomic chemotherapy group were treated with capecitabine 500 mg, 2 times/d and continuous oral administration. The conventional chemotherapy group received capecitabine 1 250 mg, 2 times/d for 14 days, rested for 7 days, 21 days was a course of treatment.After two courses,the clinical efficacy,toxicity and quality of life were evaluated. Results There were no significant differences in RR and DCR between the metronomic chemotherapy group and conventional chemotherapy group (RR: 39.3 % vs. 42.8 %, DCR: 89.3 % vs. 85.7 %, both P > 0.05). The median progression-free survival (PFS) time in the metronomic chemotherapy group was 5.8 months (95 % CI 3.23-7.44, P= 0.764) and median overall survival (OS) time was 7.9 months (95 % CI 4.15-7.95, P=0.519). The median PFS time in the conventional chemotherapy group was 7.2 months (95 % CI 3.32-6.33, P=0.835), median OS time was 10.3 months (95 % CI 4.08-7.37, P=0.463). There was no significant difference between the two groups (both P> 0.05). The incidences of hand-foot syndrome, myelosuppression and digestive tract reaction in conventional chemotherapy group were higher than those in metronomic chemotherapy group, there were significant differences between the two groups (all P < 0.05). No Ⅲ-Ⅳ level adverse reactions were found in the metronomic chemotherapy group. The overall rate of improvement of the quality of life in the metronomic chemotherapy group was significantly higher than that in the conventional chemotherapy group (92.9 % vs. 78.8 %, χ 2= 7.629, P < 0.05). Conclusion The clinical efficacy of capecitabine metronomic chemotherapy in the maintenance of elderly patients with metastatic breast cancer is similar to conventional dose maintenance therapy,but it can not only reduce the side effects, but also improve the quality of life of patients.

Progress on metronomic chemotherapy for advanced hepatocellular carcinoma / 中国肿瘤临床

Primary liver cancer,particularly hepatocellular carcinoma(HCC),is a common type of digestive tumor in China.The majority of HCC patients is diagnosed with advanced stage and thus cannot be treated with surgery and local treatment.Systemic therapy is considered to be the main treatment of advanced HCC.The effect of traditional cytotoxic drug chemotherapy on advanced HCC is not evident.Although sorafenib,a molecular-targeted drug,has survival benefits,this drug is expensive and has low objective effective rate of only 2%-3%. Metronomic chemotherapy has received increasing attention because it targets tumor angiogenesis for the treatment of advanced metastatic cancer.This article aimed to review the progress of metronomic chemotherapy in advanced HCC treatment.
