Use of the epidermal growth factor receptor inhibitors gefitinib, erlotinib, afatinib, dacomitinib, and icotinib in the treatment of non-small-cell lung cancer: a systematic review.

INTRODUCTION: This systematic review addresses the use of epidermal growth factor receptor (egfr) inhibitors in three populations of advanced non-small-cell lung cancer (nsclc) patients-unselected, selected, and molecularly selected-in three treatment settings: first line, second line, and maintenance. METHODS: Ninety-six randomized controlled trials found using the medline and embase databases form the basis of this review. RESULTS: In the first-line setting, data about the efficacy of egfr tyrosine kinase inhibitors (tkis) compared with platinum-based chemotherapy are inconsistent. Results from studies that selected patients based on clinical characteristics are also mixed. There is high-quality evidence that an egfrtki is preferred over a platinum doublet as initial therapy for patients with an activating mutation of the EGFR gene. The egfrtkis are associated with a higher likelihood of response, longer progression-free survival, and improved quality of life. Multiple trials of second-line therapy have compared an egfrtki with chemotherapy. Meta-analysis of those data demonstrates similar progression-free and overall survival. There is consequently no preferred sequence for second-line egfrtki or second-line chemotherapy. The egfrtkis have also been evaluated as switch-maintenance therapy. No molecular marker could identify patients in whom a survival benefit was not observed; however, the magnitude of the benefit was modest. CONCLUSIONS: Determination of EGFR mutation status is essential to making appropriate treatment decisions in patients with nsclc. Patients who are EGFR mutation-positive should be treated with an egfrtki as first-line therapy. An egfrtki is still appropriate therapy in patients who are EGFR wild-type, but the selected agent should be administered as second- or third-line therapy.

Biomarker testing and time to treatment decision in patients with advanced nonsmall-cell lung cancer.

BACKGROUND: Testing for EGFR mutations and ALK rearrangement has become standard in managing advanced nonsmall-cell lung cancer (NSCLC). However, many institutions in Europe, North America and other world regions continue to face a common challenge of facilitating timely molecular testing with rapid result turnaround time. We assessed the prevalence of biomarker testing for advanced NSCLC patients and whether testing affected the timeliness of treatment decisions. METHODS: We conducted a retrospective chart review of a random sample of one-quarter of all patients with advanced NSCLC referred to the Princess Margaret Cancer Centre from 1 April 2010 to 31 March 2013. RESULTS: Of 300 patients reviewed, 175 seen by medical oncology had nonsquamous NSCLC, 72% of whom had biomarker testing carried out. Patients tested for biomarkers were more likely to be female (47% versus 21%, P = 0.002), Asian (27% versus 6%, P = 0.005) and never smokers (42% versus 8%, P < 0.0001). Only 21% of patients with biomarker testing had results available at their initial oncology consultation. This group had a shorter median time from consultation to treatment decision (0 versus 22 days, P = 0.0008) and time to treatment start (16 versus 29, P = 0.004). Thirteen percent underwent repeat biopsy for molecular testing after the initial consultation. Of those with positive EGFR or ALK results, 19% started chemotherapy before biomarker results became available. CONCLUSIONS: Awaiting biomarker testing results can delay treatment decisions and treatment initiation for patients with advanced NSCLC. This may be avoided by incorporating reflex biomarker testing into diagnostic algorithms for NSCLC at the level of the pathologist, and further education of specialists involved in obtaining diagnostic cancer specimens to ensure they are sufficient for molecular testing.

Randomized phase II trial of pemetrexed/cisplatin with or without CBP501 in patients with advanced malignant pleural mesothelioma.

BACKGROUND: CBP501, a synthetic duodecapeptide, increases cisplatin influx into tumor cells through an interaction with calmodulin enhancing cisplatin cytotoxicity, and effects cell cycle progression by abrogating DNA repair at the G2 checkpoint. In phase I clinical trials of CBP501 alone or in combination with cisplatin, the most common toxicity was infusion-related urticaria. Activity of CBP501 plus cisplatin was observed in patients with ovarian cancer and mesothelioma, including some patients previously treated with cisplatin. METHODS: Chemotherapy naïve patients with unresectable MPM were stratified by histology and performance status, and randomized 2:1 to pemetrexed/cisplatin plus CBP501 25mg/m(2) IV (Arm A) or pemetrexed/cisplatin alone (Arm B). The primary endpoint was progression free survival (PFS) at 4 months. RESULTS: 65 patients were randomized, and 63 were treated. Patient characteristics in the two arms were balanced. Based on independent radiology review of the treated population, 25/40 patients (63%) in Arm A and 9/23 (39%) in Arm B had PFS≥4mo; the median PFS was 5.1mo (95% CI, 3.9, 6.5) vs 3.4mo (2.5, 6.7). Median OS was 13.3mo (9.2, 16.3) in Arm A and 12.8 (6.5, 16.1) in Arm B. Adverse events were not different than expected from standard chemotherapy, and comparable in the two arms, aside from infusion reactions which occurred in 70% of patients treated with CBP501. CONCLUSIONS: While this randomized phase II trial met its primary endpoint of PFS at 4 months, other parameters such as response rate and overall survival suggest that the addition of CBP501 does not improve the efficacy of standard chemotherapy for MPM.

A case of recurrent metastatic ameloblastoma and hypercalcaemia successfully treated with carboplatin and paclitaxel: long survival and prolonged stable disease.

We describe a case of recurrent metastatic malignant ameloblastoma to the lungs with hypercalcaemia in a 47-year-old man. The first lung metastasis was resected nine years after the initial primary, and the tumour recurred with extensive pulmonary metastases 21 years after the primary tumour was resected. This case presented with malignancy-associated hypercalcaemia, likely due to paraneoplastic syndrome, which is exceedingly unusual in association with malignant ameloblastoma. He was successfully treated with carboplatin/paclitaxel and showed the longest survival and stable disease, from the diagnosis of recurrent metastasis, recorded as a case report. This regimen is reasonably well tolerated and can be repeated safely.

Adjuvant chemoradiation for gastric cancer with infusional 5-fluorouracil and cisplatin: a phase I study.

OBJECTIVE: This phase I study aimed to determine the maximal tolerated dose of cisplatin administered every 2 weeks with infusional 5-fluorouracil (5FU) and concurrent radiation therapy (RT) in patients after complete resection of gastric adenocarcinoma. METHODS: Patients with resected stage IB to IV (M0) gastric adenocarcinoma were treated with 12 weeks of infusional 5FU (200 mg/m(2) daily) and with RT (45 Gy in 25 fractions starting on day 16). Cisplatin was administered in escalating doses (0, 20, 30, and 40 mg/m(2)) in weeks 1, 3, 5, and 7. In the final cohort, patients received an additional dose of cisplatin (40 mg/m(2)) in week 9. RESULTS: Among the 34 patients [median age: 56 years (range: 31-77 years)] who were assessable for toxicity, 5 experienced dose-limiting toxicities: 1 sepsis (cohort 1), 1 fatigue (cohort 2), 3 upper gastrointestinal toxicity (1 in cohort 2, 2 in cohort 5). Cohort 5 exceeded the maximal tolerated dose. Median follow-up was 2.5 years (range: 0.3-5 years). The 3-year overall and relapse-free survival rates were 86% and 71% respectively; median survival was not reached. CONCLUSIONS: Cisplatin was well tolerated in combination with infusional 5FU and RT, showing promising activity in the adjuvant treatment of gastric cancer. Infusional 5FU 200 mg/m(2) daily for 12 weeks with cisplatin 40 mg/m(2) in weeks 1, 3, 5, and 7 and with concurrent RT 45 Gy in 25 fractions, starting at day 16, is being explored in a phase II study at our institution.

Enhancing treatment decision-making: pilot study of a treatment decision aid in stage IV non-small cell lung cancer.

We developed a decision aid (DA) for patients with metastatic non-small cell lung cancer (NSCLC), to better inform patients of their prognosis and treatment options, and facilitate involvement in decision-making. In a pilot study, 20 patients with metastatic NSCLC attending outpatient clinics at a major cancer centre, who had already made a treatment decision, reviewed acceptability of the DA. The median age of the patients was 61 years (range 37-77 years), 35% were male, 20% had a university education, and most (75%) had English as a first language. Most had received chemotherapy, with 65% currently on treatment. Patients were not anxious at baseline and had clear understanding of the goals and toxicity of chemotherapy in advanced NSCLC. After reviewing the DA, patients' anxiety decreased slightly (P=0.04) and knowledge scores improved by 25% (P<0.001). Most improvements in understanding were of prognosis with and without chemotherapy, although patients still believed advanced NSCLC to be curable. Patients rated the DA highly with respect to information clarity, usefulness and were positive about its use in practice, although 40% found the prognostic information slightly upsetting. The DA for advanced NSCLC is feasible, acceptable to patients and improves understanding of advanced NSCLC without increasing patient anxiety.

The impact of anemia on outcome of chemoradiation for limited small-cell lung cancer: a combined analysis of studies of the National Cancer Institute of Canada Clinical Trials Group.

BACKGROUND: Associations between anemia and outcomes of chemoradiation have been documented in several malignancies, but few data exist for limited small-cell lung cancer (LD-SCLC). This combined analysis of 652 patients in two randomized clinical trials in LD-SCLC carried out by the National Cancer Institute of Canada Clinical Trials Group was undertaken to explore the relationship between anemia at baseline and anemia arising during therapy, and outcomes of chemoradiation in this cancer. PATIENTS AND METHODS: The relationships between overall survival and local control with hemoglobin levels at baseline and those arising during therapy (nadir hemoglobin (Hb) and maximum percentage drop from baseline values) were explored. RESULTS: No Hb parameter was associated with either outcome. Baseline anemia was found in one-third of patients, was more common in males, in those with a poorer performance status and those with an elevated lactate dehydrogenase; all of these latter factors were associated with shorter survival. A trend towards improved local control in patients with the greatest drop in their Hb did not remain significant in a multivariate analysis. CONCLUSIONS: Anemia is common in patients with LD-SCLC. Anemia at diagnosis may have a different prognostic implication than that arising during therapy, and correction of anemia may have no impact on outcomes.

Transarterial chemoembolisation for advanced hepatocellular carcinoma: results from a North American cancer centre.

AIMS: In Asian countries, transarterial chemoembolisation (TACE) has long been used for palliation of unresectable hepatocellular carcinoma (HCC) without strong evidence of improved survival or quality of life. In 2002, a survival benefi of TACE was shown in two randomised controlled trials in Europe and Hong Kong. The effectiveness of interventions fo HCC is influenced by geographical factors related to diverse patient characteristics and protocols. Therefore, the validation of TACE as palliative modality for unresectable HCC requires confirmation in diverse patient populations. The aim of the present study was to assess the effectiveness of TACE for HCC in a North American population. MATERIALS AND METHODS: This was a single centre prospective cohort study. Child-Pugh A cirrhosis or better patients wit unresectable HCC and without radiological evidence of metastatic disease or segmental portal vein thrombosis wer assessed between November 2001 and May 2004. Of 54 patients who satisfied the inclusion criteria, 47 underwent 80 TACE sessions. Chemoembolisation was carried out using selective hepatic artery injection of 75 mg/m(2) doxorubicin and lipiodol followed by an injection of embolic particles when necessary. Repeat treatments were carried out at 2-3 month intervals for recurrent disease. The primary outcome was overall survival; secondary outcomes were morbidity and tumour response. RESULTS: The survival probabilities at 1, 2 and 3 years were 76.6, 55.5 and 50%, respectively. At 6 months after the first intervention, 31% of patients had a partial response and 60% had stable disease by RECIST criteria. Minor adverse events occurred after 39% of TACEs and major adverse events after 20% of sessions, including two treatment-related deaths (4% of patients). One patient had complete cancer remission after undergoing three TACE treatments. Further progression of tumour growth was prevented in 91% of tumours at the 6 month point after the first TACE. At 3 months, serum levels of the tumour marker alpha-feto protein were significantly reduced in patients with elevated levels before TACE. CONCLUSIONS: The survival probabilities at 1 and 2 years after TACE were comparable with results in randomised studies from Europe and Asia. Most patients tolerated TACE well, but clinicians need to be aware that moderately severe sideeffects require close monitoring and prompt intervention.

Mental health and vitality among Canadian women with physical disabilities.

This study investigated scores for mental health and vitality in a large community-based sample of women with physical disabilities. The scores from two subscales of the SF-36 were collected from 1,096 women with physical disabilities through a mailed survey regarding health and well-being. These scores were compared to normative data using t tests. The mean scores of the vitality subscale were significantly lower than that of the normed sample when analyzed by age groups. The mental health scores were significantly lower as well, except for one age group (65-74 yr.). These results suggest that health care workers should address aspects of mental health and energy when caring for women with physical disabilities, as these areas are often overlooked in this population. Health promotion programs aimed at these topics should be designed specifically for this population as well.

The palliative benefit of irinotecan in 5-fluorouracil-refractory colorectal cancer: its prospective evaluation by a Multicenter Canadian Trial.

Most patients with colorectal cancer (CRC) who have failed initial 5-fluorouracil (5-FU) chemotherapy have worsening of disease-related symptoms (DRS) and quality of life (QOL). Irinotecan has a reported response rate of 10%-20% in such patients. The aim of this phase II trial was to prospectively determine the palliative benefit of irinotecan utilizing DRS as primary endpoints of response. Patients had advanced CRC refractory to 5-FU with at least 1 DRS defined as (1) Karnofsky performance status (KPS) 60%-80%, (2) baseline analgesic use > or = 10 mg morphine/day (or equivalent), or (3) disease-related pain score > 1 cm on a 10-cm linear analogue self-assessment (LASA) scale. Patients received irinotecan 125 mg/m2 weekly for 4 weeks on an every-6-weeks schedule. The primary endpoint was palliative response defined as > or = 50% decrease in pain score or analgesic usage, or 10% increase in KPS, from baseline for 4 weeks. QOL was assessed by the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core 30 (EORTC QLQ-C30) version 2 instrument. A total of 65 patients were entered onto the study. Median baseline parameters were KPS 70%, analgesic score 11 mg/day, and pain score 2.4 cm. A palliative response was achieved in 27 patients (42%), improvement in pain score predominated. LASA and EORTC QLQ-C30 instruments showed parallel changes in DRS. The radiological response rate was 11% (complete responses and partial responses, n = 46); 23 patients achieved stable disease. Median overall survival was 7.2 months. Irinotecan provides a rate of palliative benefit higher than the radiological response rate. Patients-oriented palliative endpoints can be useful in assessing the benefit of agents in early-phase clinical trials.

Intraoperative sonographic localization of breast masses: success with specimen sonography and surgical bed sonography to confirm excision.

OBJECTIVE: To assess the use of intraoperative sonography for localization of breast masses at excisional biopsy, with specimen and surgical bed sonography to confirm excision. METHODS: A computer search of the 5-year period from January 1993 through January 1998 revealed 138 consecutive women referred for sonographically guided excisional biopsy of 148 masses; 35 masses were excluded because they had no postoperative mammograms. One hundred thirteen masses constituted the study group. Specimen sonography (n = 60) or surgical bed sonography (n = 53) was performed as the initial evaluation to confirm excision, but ultimately, surgical bed sonography may have been necessary after specimen sonography, and specimen sonography may have been necessary after surgical bed sonography. The miss rates determined by postoperative imaging were calculated for each group and compared with those of mammographically guided needle localization series from the literature. RESULTS: Follow-up physical examination and mammography showed no residual mass in the region of surgery in any patient. However, follow-up sonography had 1 miss in the initial specimen sonogram group (1 [1.7%] of 60) and 1 miss in the initial surgical bed group (1 [1.9%] of 53). As shown by the Fisher exact test, there was no significant difference between the miss rates of the 2 initial methods of confirming lesion excision or between the miss rates of these initial methods, both groups combined, and 6 mammographic localization series from the literature. CONCLUSION: Intraoperative breast sonography, using specimen sonography and scanning the surgical bed, has miss rates comparable with those of mammographic needle localization. Follow-up sonography must be performed if there is any doubt of complete excision.

Metallothionein expression in patients with small cell carcinoma of the lung: correlation with other molecular markers and clinical outcome.

BACKGROUND: Patients with small cell carcinoma of the lung (SCLC) are known to have an extremely poor prognosis, with a 5-year survivor rate of only 5%. Chemotherapeutic drug resistance is a major obstacle to curative therapy in patients with SCLC. METHODS: The authors evaluated retrospectively the expression of metallothionen (MT), proliferating cell nuclear antigen (PCNA), p53, and retinoblastoma gene product (RBGP) in biopsy samples from 58 patients with SCLC prior to standard chemotherapy. The objective was to study the correlation between MT and other molecular markers in SCLC and correlate these data with the clinical outcome of patients. The authors studied 28 short-term survivors (STS; survival < 24 months) and 30 long-term survivors (LTS; survival > 24 months). RESULTS: In line with expectations, the authors found a strong inverse association between stage and survival. Of 58 patients with SCLC, 26 patients (45%; 17 STS and 9 LTS) showed MT expression, 55 patients (94%; 28 STS and 27 LTS) were positive for PCNA, 28 patients (48%; 16 STS and 12 LTS) were positive for p53, and only 6 patients (10%; 1 STS and 5 LTS) showed positivity for RBGP. On comparing the percent positivity of various markers in the two survivor groups, there was greater frequency of expression of MT, PCNA, and p53 and lower RBGP expression in the STS group compared with the LTS group. However, only the difference in expression of MT between the two survivor groups was statistically significant (Fisher exact test; P = 0.034). Multivariable analysis using a logistic regression model showed a significant association between MT expression and patient survival after adjusting for disease stage (chi-square test; P = 0.022). There was also a statistically significant association between MT expression and p53 expression (chi-square test; P = 0.001). CONCLUSIONS: In this study, of the molecular markers studied, the authors demonstrated that only MT overexpression was independently predictive of short-term survival in patients with SCLC undergoing chemotherapy.

Comparison of unenhanced and contrast-enhanced spiral CT for assessing interval change in patients with colorectal liver metastases.

RATIONALE AND OBJECTIVES: The purpose of this study was to determine whether the interval change in hepatic colorectal metastases as assessed with serial computed tomographic (CT) scans without contrast material enhancement differs from that as assessed using serial, portal dominant phase, contrast-enhanced CT scans. MATERIALS AND METHODS: Unenhanced and contrast-enhanced abdominal CT scans were obtained in 28 patients. Three radiologists separately reviewed serial unenhanced and contrast-enhanced studies to assess the interval change in liver metastases. These radiologists recorded total number of lesions, bidimensional measurements of the largest lesions (as many as three), and overall impressions regarding the interval change (none, worse, or better). RESULTS: Among the 84 judgments (28 patients x 3 radiologists), comparisons of unenhanced and contrast-enhanced CT studies were concordant in 60 assessments (71%). Nineteen (23%) showed mild disagreement. Of these, contrast-enhanced CT studies demonstrated disease stability when unenhanced CT studies demonstrated otherwise in 11 judgments, whereas unenhanced CT studies demonstrated stability when contrast-enhanced CT studies demonstrated otherwise in eight assessments. Furthermore, of the five marked disagreements, two resulted from a conclusion of interval improvement on unenhanced CT studies and a conclusion of interval worsening on contrast-enhanced CT studies, whereas three demonstrated the opposite. Neither set of serial CT studies systematically resulted in under- or overestimation of disease progression (McNemar Q test, P < .25). CONCLUSION: The authors found no consistent pattern to demonstrate that serial unenhanced or contrast-enhanced CT studies resulted in over- or underestimation of disease progression.

Sonographically guided renal mass biopsy: indications and efficacy.

PURPOSE: To review the clinical indications, pathologic results, and success rate of all our sonographically guided solid renal mass biopsies over a 5-year period. METHODS: Between 1993 and 1998, 44 consecutive patients underwent sonographically guided percutaneous biopsy of a solid renal mass. Indications included prior history of nonrenal malignancy, metastatic disease of unknown primary origin, previous contralateral nephrectomy for a renal cell neoplasm, a renal transplant mass, suspected renal lymphoma, history of tuberous sclerosis, and poor surgical candidacy. Aspiration biopsies were initially performed with 22- to 18-gauge spinal needles. If the initial cytologic evaluation findings were nondiagnostic, core biopsies were then performed with 20- to 18-gauge core biopsy guns. Dictated sonographic reports of the biopsies were reviewed to determine the following: indication for biopsy, location and size of the renal mass, needle gauge and type, number of needle passes, and complications. Final cytologic and surgical pathologic records were reviewed. RESULTS: Thirty-six (82%) of the 44 biopsy specimens were diagnostic. Aspirated smears were diagnostic in 24 (67%) of these cases, with the diagnosis made on the basis of cell block alone in an additional 2 (6%). A definitive diagnosis came from core biopsy alone in 10 cases (28%). The 18-gauge core needle yielded diagnostic results more reliably than the 20-gauge core needle, and a significant correlation was seen between core biopsy needle size and the rate of diagnostic core samples (P = .017). Pathologic diagnoses included renal cell carcinoma (n = 18), lymphoma (n = 4), oncocytic neoplasm (n = 4), transitional cell carcinoma (n = 2), angiomyolipoma (n = 1), papillary cortical neoplasm (n = 1), and metastatic carcinoma (n = 6). Complications were seen in 4 (9%) of 44 cases; all were treated conservatively. CONCLUSIONS: For specific clinical indications, sonographically guided fine-needle aspiration and core biopsy of a solid renal mass can be performed safely. In many cases, a definitive diagnosis can be made on the basis of fine-needle aspiration alone. However, diagnosis may ultimately require core biopsy, for which 18-gauge core needles would be more reliably diagnostic than 20-gauge needles.

Pretreatment motivational enhancement therapy for eating disorders: a pilot study.

UNLABELLED: Eating disorder patients are notoriously ambivalent about treatment and often lack motivation to change. These characteristics may decrease the number of patients entering treatment and increase the number of patients dropping out of treatment prematurely. OBJECTIVE: The aim of this pilot study was to develop and evaluate a motivational enhancement therapy (MET) group program for eating disorder patients. The goal of the MET intervention was to increase participants' motivation to change, which might be expected to increase the success of future treatment of patients with eating disorders. METHOD: Nineteen individuals who were referred for specialized treatment took part in the study. The intervention was based on existing literature in the field of addictions and modified for eating disorders. RESULTS: The motivational measures suggested that the participants' motivation to change increased following the intervention. A decrease in depressive symptoms and an increase in self-esteem were also found. DISCUSSION: The results of this study suggest that MET could be valuable for the treatment of eating disorder patients and provide a rationale to conduct further research in this area.

Randomized, double-blind, multicenter trial comparing clinafloxacin with imipenem as empirical monotherapy for febrile granulocytopenic patients.

In a double-blind, multicenter trial, 541 febrile granulocytopenic patients were randomized to receive either intravenous (iv) clinafloxacin (200 mg every 12 h) or i.v. imipenem (500 mg every 6 h) as empirical monotherapy. More baseline pathogens were susceptible to clinafloxacin (259 [99%] of 262 organisms) than to imipenem (253 [95%] of 265; P=.03). Initial favorable clinical response rates for clinafloxacin (88 [32%] of 272 patients) and imipenem (89 [33%] of 269) were similar. After addition of other antimicrobial agents, overall response rates were 259 (95%) of 272 for clinafloxacin and 251 (93%) of 269 for imipenem. During the study, only 13 clinafloxacin (5%) and 18 imipenem (7%) recipients died. Both drugs were generally well tolerated. Drug-related skin rash occurred more often with clinafloxacin (11% vs. 6%; P=.07), whereas nausea (2% vs. 5%; P=.16), Clostridium-difficile-associated diarrhea (3% vs. 8%; P=.02), and seizures (0% vs. 2%; P=.06) occurred more often with imipenem. These results suggest that clinafloxacin and imipenem have similar efficacy as empirical monotherapy in febrile granulocytopenic patients.

Decompression of multiple pneumatoceles in a premature infant by percutaneous catheter placement.

Pneumatoceles due to acquired localized overinflation as a form of pulmonary interstitial emphysema are complications of advanced bronchopulmonary dysplasia. Different ventilation modes, selective bronchial intubation, balloon obstruction of the affected bronchus and steroids have been reported with success. Lobectomy has also been used. We present a premature infant with multiple large pneumatoceles causing respiratory compromise. In our case percutaneous decompression under fluoroscopy guidance resulted in a permanent cure.

Chemotherapy-induced oral mucositis. Prevention and management.

Oral mucositis is a frequent and potentially severe complication of chemotherapy which has a considerable impact on patient quality of life. While the management of other chemotherapy-related toxicities has improved, the incidence of mucositis is increasing. A critical review of the literature published between 1985 and 1999 reveals very few strategies or agents with proven efficacy, leaving few recommendations for the standard care in the prevention and treatment of mucositis at this time. Recommendations that can be made include: reducing patient risk factors, implementing proven preventative interventions such as utilising oral ice chips with fluorouracil chemotherapy, and optimising supportive care practices individualised to the patients' needs and symptoms. Progress in understanding the pathophysiology of mucositis at the molecular level has led to the evaluation of a number of new investigational agents, specifically those directed to the epithelial mucosa, such as mitogens and epithelial growth factors. These appear to be very promising in preclinical studies. Randomised clinical trials with these agents may finally demonstrate an impact on the clinical practice of mucositis management in the coming years.
