Evidence based whole breast hypo-fractionated radiation therapy in patients with early breast cancer.

PURPOSE: The aim of the current study was to evaluate the efficacy and tolerability of hypo-fractionated whole breast radiation therapy in patients with early breast cancer. METHODS: Searching electronically PubMed and the Cochrane Central Register we made a comprehensive literature review regarding the randomized controlled phase III trials for hypo-fractionated radiation therapy in early breast cancer. RESULTS: The collected and analyzed data showed that a short course of hypo-fractionated radiation therapy in early breast cancer patients is as effective as the conventional long course regarding tumor response as well as long term side effects. CONCLUSION: More data are needed about the usage and integration of a boost treatment for higher-risk women receiving neo-adjuvant or adjuvant chemotherapy, or the results in special subgroups such as women with large breast size.

Effectiveness and Tolerability of Natural Herbal Formulations in the Prevention of Radiation-Induced Skin Toxicity in Patients Undergoing Radiotherapy.

The aim of this study is to investigate the preventive role of 3 herbal formulation products on reducing the incidence of radiation-induced dermatitis in patients undergoing radiotherapy for either breast or head and neck cancer. A total of 59 patients participated in the study. The novel herbal products, a combination of beeswax, olive oil, Calendula and Hypericum oils and Aloe gel, were daily and regularly being used by the patients during radiotherapy and 2 weeks after treatment end. Acute skin toxicity was scored weekly during radiotherapy and after treatment for a further 4-week follow-up period. Demographic data were analyzed by descriptive statistics. Statistical analyses of the study objectives were based on an intent-to-treat principle. Most of the patients presented with grade I (RTOG/EORTC) toxicity in the first weeks of radiotherapy, progressed to grade II but reverted to grade I toxicity up until the study end. A total of 94.9% of the patients had Dermatology Life Quality Index up to 1, and 66.1% remained in this scale. The application of the novel natural product combinations proved to be statistically significantly effective in reducing the intensity of radiation dermatitis, positively affecting the quality of life of the patients.

Which is the best neoadjuvant (pre-surgery) chemoradiation regimen for locally advanced rectal carcinoma? Short or long course of radiation therapy? Do we have new data?

PURPOSE: Surgical resection is the cornerstone of curative treatment for rectal adenocarcinomas. For extensive invasive tumors, preoperative radiotherapy and chemoradiotherapy have been utilized to promote tumor regression in an attempt to convert a planned abdominoperineal resection to a sphincter-sparing surgical procedure. In order to find out which of the currently radiation therapy treatment regimen used preoperatively for rectal cancer is the best we conducted a comprehensive literature search. METHODS: We searched the Cochrane Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE database up to December 2018 for trials comparing the short and long term radiation therapy regimens for rectal carcinoma associated or not with chemotherapy. RESULTS: The search of the literature identified 38 papers related to the subject. After analysis and evaluation, 11 eligible trials were included for review. The optimal fractionation and timing of surgery in relation to radiotherapy was still controversial. Randomized trials showed that if surgery is delayed after 5×5 Gy and consolidation chemotherapy is added between 5×5 Gy and surgery, such a combination results in better short term overall survival and lower acute toxicity. CONCLUSION: Long-course radiotherapy with delay seems not to be different than short-course radiotherapy with delay, but prolongs substantially the treatment time.

Temozolomide with radiation therapy in high grade brain gliomas: pharmaceuticals considerations and efficacy; a review article.

Malignant gliomas (glioblastoma multiforme and anaplastic astrocytoma) which have a combined incidence of 5-8/100,000 population, represent the most common primary central nervous system tumors. The treatment outcomes even with aggressive approach including surgery, radiation therapy and chemotherapy are dismal with median reported survival is less than 1 year. Temozolomide is a new drug which has shown promise in treating malignant gliomas and other difficult-to-treat tumors. This drug is a per os (p.o) imidazotetrazine second-generation alkylating agent which represents the leading compound in a new class of chemotherapeutic agents that enter the cerebrospinal fluid and do not require hepatic metabolism for activation. The efficacy of temozolomide was tested in vitro studies and has demonstrated schedule-dependent antitumor activity against highly resistant malignancies, including high-grade glioma (HGG). In addition, in clinical studies, temozolomide consistently demonstrates reproducible linear pharmacokinetics with approximately 100% p.o. bioavailability, noncumulative minimal myelosuppression that is rapidly reversible, and activity against a variety of solid tumors in both children and adults. Moreover, preclinical studies have evaluated the combination of temozolomide with other alkylating agents and inhibitors of the DNA repair protein O(6)-alkylguanine alkyltransferase to overcome resistance to chemotherapy in malignant glioma and malignant metastatic melanoma. At the present time temozolomide is approved in the United States for the treatment of adult patients with refractory anaplastic astrocytoma and, in the European Union, for treatment of glioblastoma multiforme showing progression or recurrence after standard therapy. Temozolomide's characteristics which make it a candidate for a wide range of clinical testing to evaluate the potential of combination treatments in different tumor types are its predictable bioavailability and minimal toxicity. An overview of the mechanism of action of temozolomide and a summary of results from more important randomized controlled clinical trials in high grade gliomas are presented here.

Granulosa cell tumor of the ovary: tumor review.

Granulosa cell tumors of the ovary are rare neoplasms that originate from sex-cord stromal cells. The long natural history of granulosa cell tumors and their tendency to recur years after the initial diagnosis are the most prominent of their characteristics. The secretion of estradiol is the reason for signs at presentation such as vaginal bleeding and precocious puberty. Abdominal pain and hemoperitoneum, which occasionally can occur, are attributable to tumor rupture. The most common finding in pelvic examination is a tumor mass, which is subsequently confirmed with imaging techniques. Surgery is the mainstay of initial management for histological diagnosis, appropriate staging, and debulking. A more conservative unilateral salpingo-oophorectomy is indicated in patients with stage I disease and patients of reproductive age. Total abdominal hysterectomy with bilateral salpingo-oophorectomy is the appropriate surgical treatment for postmenopausal women and those with more advanced disease. The stage of disease is the most important prognostic factor associated with the risk of relapse. There are no clear conclusions regarding the role of postoperative chemotherapy or radiotherapy in stage I disease and in those with completely resected tumor. The use of adjuvant chemotherapy or radiotherapy has sometimes been associated with prolonged disease-free survival and possibly overall survival. Chemotherapy is the treatment of choice for patients with advanced, recurrent, or metastatic disease, and BEP (bleomycin, etoposide, and cisplatin) is the preferred regimen. Although the overall rate of response to treatment is high, the impact of treatment on disease-free or overall survival is unknown. Prolonged surveillance is mandatory because tumors tend to recur years after the initial diagnosis.

Efficacy of the oral fluorouracil pro-drug capecitabine in cancer treatment: a review.

Capecitabine (Xeloda) was developed as a pro-drug of fluorouracil (FU), with the aim of improving tolerability and intratumor drug concentrations through its tumorspecific conversion to the active drug. The purpose of this paper is to review the available information on capecitabine, focusing on its clinical effectiveness against various carcinomas. Identification of all eligible English trails was made by searching the PubMed and Cochrane databases from 1980 to 2007. Search terms included capecitabine, Xeloda and cancer treatment. Nowadays, FDA has approved the use of capecitabine as a first line therapy in patients with metastatic colorectal cancer when single-agent fluoropyrimidine is preferred. The drug is also approved for use as a single agent in metastatic breast cancer patients who are resistant to both anthracycline and paclitaxel-based regimens or when further anthracycline treatment is contraindicated. It is also approved in combination with docetaxel after failure of prior anthracycline-based chemotherapy. In patients with prostate, pancreatic, renal cell and ovarian carcinomas, capecitabine as a single-agent or in combination with other drugs has also shown benefits. Improved tolerability and comparable efficacy, compared with the intravenous FU/LV combination, in addition to its oral administration, make capecitabine an attractive option for the treatment of several types of carcinomas.

Responsibilities in cancer preventive care in Greece. A physicians' survey.

BACKGROUND: Colorectal cancer is the second leading cause of cancer death in European countries. Differences in screening implementation may explain USA vs. European survival differences. The proportion of European primary care physicians advising colorectal screening has been reported to be inconsistent. We therefore hypothesised the presence of a belief-related bias among European physicians regarding who is responsible for cancer screening delivery. OBJECTIVES: To index beliefs in cancer screening implementation among a wide sample of Greek physicians. Study design Cross-sectional survey. METHODS: Three hundred and sixty-six physicians involved in primary care activities in 15 provinces answered a questionnaire about responsibility in cancer screening delivery. Results 22.4% and 7.6% of physicians declared that the health system and the patients, respectively, have the main responsibility for cancer screening implementation, while 70 % advocated patient-health system co-responsibility. Beliefs were statistically correlated to age (p=0.039) and specialisation category (p=0.002). Patients' will was mainly indicated by internists, trainee internists and physicians older than 30, while GPs, trainee GPs and house officers were mainly health system-oriented. Worryingly, when physicians were asked about which specialty should inform the population, 81% indicated family doctor (for-fee-service) while the involvement of free-from-fee specialities was inconsistent. CONCLUSION: A considerable disorientation about responsibilities in cancer screening delivery was observed in our study sample. Continual medical education and clear redefinition of primary care physicians' activities are required.

Old habits die hard: chest radiography for screening purposes in primary care.

OBJECTIVE: To assess whether the use of chest radiography for screening changes over time. DESIGN: Systematic review. DATA SOURCES: MEDLINE, ISI, Cochrane Central Register of Controlled Trials, and handsearching of selected journals. REVIEW METHODS: We evaluated whether the proportion of primary care physicians using chest radiography to screen for (1) malignancy in the general asymptomatic population, (2) malignancy in a high-risk subgroup, (3) any disease in the general population, and (4) any disease in a high-risk subgroup changed over time, using random-effects meta-regression analysis. Adjustments for the availability of national guidelines were also performed. RESULTS: Overall, 10% to 90% of primary care physicians reported using chest x-ray for screening. In unadjusted analyses, the proportion of physicians using chest radiography for cancer screening in the general population tended to increase by 0.9% per year (8 studies, n = 4313). The corresponding annual changes were -2.9% for cancer screening in high-risk subgroups (8 studies, n = 2784) and -0.4% regarding screening for any disease in the population (7 studies, n = 2627). No meta-regressions were run for outcome (4) (only 1 study). In the adjusted analyses, there was a decreasing nonsignificant trend for all outcomes. CONCLUSIONS: Despite formal recommendations, many physicians still use chest x-ray for screening, with their number decreasing slowly over time. This practice may be harmful because the positive predictive value of chest radiography is low, and further evaluation of false-positive findings might be associated with increased cost and risk from additional diagnostic or therapeutic interventions.

Socio-demographic status and alcohol drinking patterns among Greek healthy adults.

AIM: To analyze socio-demographic correlates of alcohol drinking among Greek healthy adults. METHODS: Data related to alcohol consumption patterns of 5500 adult individuals, coming from 26 Hellenic provinces were abstracted from SESy-Europe database within a framework of the nationwide Hellenic anticancer-trial PACMeR 02 study. Statistic: chi2 test and logistic regression analyses were used. RESULTS: 42.5% of males and 82.5% of females did not consume alcoholic drinks. Among users, daily alcohol assumption was 28.50 g/day for men and 9.85 g/day for women. The mainland population presented higher proportions for both abstainers and moderate-heavy drinkers. Consumption rate was higher for sub-populations living in islands, but they were mostly light drinkers rather than heavy consumers. Among males, younger subjects, farmers and craftsmen had a higher tendency for alcohol abuse. Among females, the proportion of consumers and abusers was notably more elevated among younger individuals, especially among those living in urban areas of mainland, with higher educational level, employees and freelance professionals. A particular attention to the newly and rapidly growing patterns of alcoholism among young females should be given and prevention programs should be promptly developed.

Bevacizumab for Malignant Brain Gliomas. Which is the Current Evidence?

Recently, the improvement of innovative medications named focused treatments represents the consequence of a superior knowledge of the procedures implicated in the modification of physiological tissues in tumor. Focused treatment is known as the therapy which uses specific substances that affect selective mechanisms implicated in tumorigenesis and tumor development. Angiogenesis is important for tumor development and distant metastatic disease and represents a significant aim for modern biological substances. Bevacizumab belongs to humanized recombinant antibody family which obviates vascular endothelial growth factor (VEGF) receptor fastening, and suspending genesis of new vessels and tumor development. Bevacizumab represents the primary antiangiogenic treatment authorized for usage in tumor and has FDA authorization to treat the recurrent glioblastoma multiform since 2009. Bevacizumab's efficiency for treating malignant brain gliomas along with correlated patent appliances related to this agent is discussed below.

Hemangiopericytoma of the breast: a case report and a review of the literature.

Introduction. Sarcomas of the breast are rare and hemangiopericytoma (HPC) of the breast is even rarer. Case Report. We report a case of a 43-year-old woman who presented with a 4 cm mass in her right breast. Her family history was positive for breast cancer. A fine needle aspiration indicated a malignant vascular tumor. An excision biopsy and frozen section analysis confirmed the presence of an encapsulated mesenchymal tumor. Its morphology and immunohistochemical marker profile were characteristic for a malignant hemangiopericytoma. Thus, she underwent a tumor excision without an axilla sampling. Approximately one year after the surgery the patient is well without local recurrence or metastasis disease to be observed. We also reviewed the literature and discuss the treatment options, characteristics, and immunophenotype of HPC. Conclusions. The accurate diagnosis of HPC depends on the appropriate histological and immunohistochemical examination. Surgical resection is the treatment of choice and due to scarcity of cases and unpredictable biological behavior of these tumors long term follow-up may be warranted.

Head and neck squamous cell carcinoma of unknown primary: neck dissection and radiotherapy or definitive radiotherapy.

BACKGROUND: Management of head and neck carcinoma from unknown primary (HNCUP) remains controversial, with neck dissection and radiotherapy (RT) or definitive RT both commonly used. The purpose of this study was to characterize HNCUP and retrospectively compare outcomes for patients treated with neck dissection + RT versus definitive RT. METHODS: From 1994 to 2009, 41 patients with HNCUP underwent either neck dissection + RT (n = 22) or definitive RT ± concurrent chemotherapy (n = 19) at our institution. Treatment outcomes were compared using Kaplan-Meier methods and log-rank test. RESULTS: There were no differences between patients treated with neck dissection + RT and definitive RT in overall survival (OS), progression-free survival (PFS), locoregional relapse-free survival (LRFS), freedom from locoregional failure (FFLRG), or freedom from distant failure (FFDF). Among 17 patients who underwent neck dissection + RT for whom human papillomavirus (HPV) status could be determined, HPV(+) patients trended toward improved OS (p = .06) and PFS (p = .15). CONCLUSION: Neck dissection and postoperative RT resulted in similar outcomes as definitive RT. The prognostic implications of HPV(+) nodes in HNCUP are similar to those in oropharyngeal primary cancers.

Ultrasound-assisted endocavitary HDR-Ir(192) brachytherapy for unresectable locally advanced uterine cervix carcinoma: retrospective analysis focusing the efficacy and tolerability.

PURPOSE: To evaluate the impact of uterine cavity's ultrasound to final selected length of intracavitary tandem. The efficacy and tolerability of external beam radiation plus HDR-Ir(192) brachytherapy in our cohort of patients were also estimated. MATERIALS AND METHODS: 48 women with locally advanced unresectable uterine cervix carcinoma were treated by HDR-Ir(192) endocavitary brachytherapy between January 2007 and January 2009. The median age was 63 (range 38-74). The distribution according to Federation of Gynaecology and Obstetrics (FIGO) staging system was as follows: Stage IIB, 54.16 %; IIIA, 10.4 %; IIIB, 27.0 %; and IVA, 8.3 %. HDR intracavitary brachytherapy was given weekly, beginning at the last week of whole pelvis irradiation, with a dose of 7 Gy to point A for three to four fractions. The median overall treatment time was 50 days (range 42-73 days). The median follow-up time was 2.7 years (range 3 months to 4.9 years). Multivariate analysis was performed using the Cox regression proportional hazards model. RESULTS: The complete remission rate after radiotherapy was 93.75 % (45/48). The 5-year actuarial major complication rates (Grade 3 or above) were 6.3 % overall (2.1 % proctitis, 2.1 % cystitis and 2.1 % enteritis). Estimation of the length of uterine cavity by ultrasound helped decisively in the proper placement of the intrauterine tandem inserted. CONCLUSIONS: Prior knowledge of the length of uterine cavity can facilitate the decisions regarding the proper insertion length of the tandem. Results of cervical cancer treatment with external beam radiation and HDR intracavitary brachytherapy in our hospital are encouraging.

Role of radiation therapy in neoadjuvant era in patients with locally advanced rectal cancer.

Surgery remains the primary determinant of cure in patients with localized rectal cancer, and total mesorectal excision is now widely accepted as standard of care. The widespread implementation of neoadjuvant short-course radiotherapy (RT) or long-course chemoradiotherapy (CRT) has reduced local recurrence rates from 25% to 40% to less than 10%; Preoperative RT in resectable rectal cancer has a number of potential advantages, most importantly reducing local recurrence, and down-staging effect. In this article making a comprehensive literature review searching the reliable medical data bases of PubMed and Cochrane we present all available information on the role of radiation therapy alone or in combination with chemotherapy in preoperative setting of rectal cancer. Data reported show that in locally advanced rectal cancer the addition of radiation therapy or CRT pre surgically has significantly improved sphincter prevention surgery. Moreover, the addition of chemotherapy to radiation therapy in preoperative setting has significantly improved pathologic complete response rate and loco-regional control rate without improvement in sphincter preserving surgery. Finally, the results of recently published randomized trials have shown a significant improvement of pre- vs postoperative CRT on local control; however, there was no effect on overall survival.

Has bevacizumab (Avastin) given extra therapeutic gain in metastatic colorectal cancer and malignant brain gliomas? Systematic review answering this question.

During the last decade, the development of new drugs known as targeted therapies was the result of a better understanding of the processes involved in the transformation of normal cells into cancer. The term targeted therapy refers to drugs that selectively target specific molecular pathways involved in tumourigenesis or tumour progression. Angiogenesis is important for tumour growth and metastasis and is an important target for new biological agents. Bevacizumab is a humanised recombinant antibody that prevents vascular endothelial growth factor (VEGF) receptor binding, and inhibits angiogenesis and tumour growth. On February 26, 2004, the FDA (Food and Drug Administration) approved Bevacizumab as first-line treatment for patients with metastatic colorectal cancer. The integration of targeted therapies in the treatment of colon cancer has resulted in significant improvements in efficacy outcomes. Bevacizumab was the first antiangiogenic therapy approved for use in cancer and received accelerated FDA approval for the treatment of recurrent glioblastoma multiform in 2009. The efficacy of Bevacizumab in the treatment of metastatic colorectal cancer and recurrent glioblastoma multiform is presented in this review article. The structural characteristics and selectivity profiles of this antiangiogenic drug and those disclosed in related patent applications are also summarised in this article.

Evidence based radiation therapy for locally advanced resectable and unresectable gastric cancer.

Despite the fact that gastric cancer is decreasing in incidence in the United States, it remains one of the most commonly diagnosed and most fatal cancers worldwide. In localised disease, surgery remains the cornerstone of treatment. Nevertheless, the low overall survival rates at 5 years due to locoregional and distant recurrences has led to a large debate regarding the role of radiation therapy and chemotherapy in addition to curative resection. Recent data have shown that, even with improved surgical techniques, locoregional failure rates in these patients ranged between 57% and 88%. Failures were noted in the gastric bed, regional nodes, gastric remnant, anastomosis and duodenal stump, all of which can be encompassed in a regional radiation field, indicating the need of further locoregional treatment. In this article, a comprehensive literature review of the reliable medical databases of PubMed and Cochrane is made and we present all available information on the role of radiation therapy in the preoperative and postoperative setting of gastric cancer. Data reported show that in locally advanced gastric cancer the addition of radiation therapy post surgery has significantly improved disease-free survival as well as overall survival. Moreover, in unresectable gastric cancer, the combination of radiation therapy with chemotherapy has significantly improved mean and overall survival rates. The role of radiation therapy in patients with resectable gastric cancer is being further evaluated in ongoing phase III trials.

Therapeutic interventions targeting organ preservation in muscle-invasive bladder cancer: a review.

Nowadays in modern oncology there is a tendency towards therapies that target organ preservation. Organ preservation protocols have become standard in the treatment of laryngeal carcinoma, oesophageal cancer, breast carcinoma and soft tissue sarcomas. The three-combined therapy consisting of a transurethral resection of the bladder tumour followed by concomitant chemoradiotherapy has been shown to be an attractive alternative for bladder preservation in selected patients with muscle-invasive bladder cancer. In order to evaluate the organ preservation approaches in muscle-invasive bladder cancer we have conducted a comprehensive literature review. Data reported from the studies have shown that bladder preservation therapy with a trimodality approach is safe and effective. Moreover, such an approach provides patients with the opportunity to maintain an intact and functional bladder with a survival rate similar to that of radical cystectomy.

Lymphoma of the testis as primary location: tumour review.

Non-Hodgkin's lymphoma as a primary testicular neoplasm accounts approximately 9% of all testicular malignant tumours and about 1-2% of all non-Hodgkin's lymphoma. This neoplasm is the most common malignant tumour of the testis in the elderly. The most common histotype in primary forms is the diffuse large B-cell lymphoma, whereas more aggressive histologies such as Burkitt's lymphoma are principal founded in cases of secondary involvement of the testis. Regarding clinical presentation, the most common sign is a unilateral painless scrotal swelling, sometimes with sharp scrotal pain or hydrocele. In patients with advanced stage, the systematic B symptoms are present in 25-41% of all cases. In 35% of patients, bilateral testicular involvement is detected. In more advanced stages with para-aortic lymph-node involvement, ascites and abdominal pain is evident. Despite the fact that responses to doxorubicin- containing chemotherapy, especially in early stages, show good results, relapses are often seen, and the prognosis of this tumour is very poor. Testicular lymphoma often disseminates to other extranodal organs, such as contralateral testis, central nervous system (CNS), lung, pleura, Waldeyer's ring and soft tissue. For patients with limited disease, the recommended first-line treatment is orchiectomy followed by rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) combination chemotherapy, with central nervous system (CNS) prophylaxis and prophylactic irradiation of the contralateral testis. In more advanced or relapsed disease, management should follow the worldwide recommendations for nodal diffuse large B-cell lymphoma (DLBCL). Here we present a review of this tumour.

Patient dose considerations in computed tomography examinations.

Ionizing radiation is extensively used in medicine and its contribution to both diagnosis and therapy is undisputable. However, the use of ionizing radiation also involves a certain risk since it may cause damage to tissues and organs and trigger carcinogenesis. Computed tomography (CT) is currently one of the major contributors to the collective population radiation dose both because it is a relatively high dose examination and an increasing number of people are subjected to CT examinations many times during their lifetime. The evolution of CT scanner technology has greatly increased the clinical applications of CT and its availability throughout the world and made it a routine rather than a specialized examination. With the modern multislice CT scanners, fast volume scanning of the whole human body within less than 1 min is now feasible. Two dimensional images of superb quality can be reconstructed in every possible plane with respect to the patient axis (e.g. axial, sagital and coronal). Furthermore, three-dimensional images of all anatomic structures and organs can be produced with only minimal additional effort (e.g. skeleton, tracheobronchial tree, gastrointestinal system and cardiovascular system). All these applications, which are diagnostically valuable, also involve a significant radiation risk. Therefore, all medical professionals involved with CT, either as referring or examining medical doctors must be aware of the risks involved before they decide to prescribe or perform CT examinations. Ultimately, the final decision concerning justification for a prescribed CT examination lies upon the radiologist. In this paper, we summarize the basic information concerning the detrimental effects of ionizing radiation, as well as the CT dosimetry background. Furthermore, after a brief summary of the evolution of CT scanning, the current CT scanner technology and its special features with respect to patient doses are given in detail. Some numerical data is also given in order to comprehend the magnitude of the potential radiation risk involved in comparison with risk from exposure to natural background radiation levels.

Capecitabine for locally advanced and metastatic colorectal cancer: A review.

Capecitabine (Xeloda(®)) is an oral fluoropyrimidine which is produced as a pro-drug of fluorouracil, and shows improved tolerability and intratumor drug concentrations following its tumor-specific conversion to the active drug. We have searched the Pubmed and Cochrane databases from 1980 to 2009 with the purpose of reviewing all available information on Capecitabine, focusing on its clinical effectiveness against colorectal cancer. Special attention has been paid to trials that compared Capecitabine with standard folinic acid (leucovorin, LV)-modulated intravenous 5-fluorouracil (5-FU) bolus regimens in patients with metastatic colorectal cancer. Moreover the efficacy of Capecitabine on metastatic colorectal cancer, either alone or in various combinations with other active drugs such as Irinotecan and Oxaliplatin was also assessed. Finally, neoadjuvant therapy consisting of Capecitabine plus radiation therapy, for locally advanced rectal cancer was analysed. This combination of chemotherapy and radiotherapy has a special role in tumor down staging and in sphincter preservation for lower rectal tumors. Comparative trials have shown that Capecitabine is at least equivalent to the standard LV-5-FU combination in relation to progression-free and overall survival whilst showing a better tolerability profile with a much lower incidence of stomatitis. It is now known that Capecitabine can be combined with other active drugs such as Irinotecan and Oxaliplatin. The combination of Oxaliplatin with Capecitabine represents a new standard of care for metastatic colorectal cancer. Combinating the Capecitabine-Oxaliplatin regimen with promising new biological drugs such as Bevacizumab seems to give a realistic prospect of further improvement in time to progression of metastatic disease. Moreover, preoperative chemo-radiation using oral capecitabine is better tolerated than bolus 5-FU and is more effective in the promotion of both down-staging and sphincter preservation in patients with locally advanced rectal cancer. Finally, the outcomes of recently published trials suggest that capecitabine seems to be more cost effective than other standard treatments for the management of patients with colorectal cancer.
