RESUMEN
BACKGROUND: In esophageal cancer (EC) patients who are not eligible for surgery, definitive chemoradiation (dCRT) with curative intent using cisplatinum with 5-fluorouracil (5-FU) is the standard chemotherapy regimen. Nowadays carboplatin/paclitaxel is also often used. In this study, we compared survival and toxicity rates between both regimens. PATIENTS AND METHODS: This multicenter study included 102 patients treated in five centers in the Northeast Netherlands from 1996 till 2008. Forty-seven patients received cisplatinum/5-FU (75 mg/m(2) and 1 g/m(2)) and 55 patients carboplatin/paclitaxel (AUC2 and 50 mg/m(2)). RESULTS: Overall survival (OS) was not different between the cisplatinum/5-FU and carboplatin/paclitaxel group {[P = 0.879, hazard ratio (HR) 0.97 [confidence interval (CI) 0.62-1.51]}, with a median survival of 16.1 (CI 11.8-20.5) and 13.8 months (CI 10.8-16.9). Median disease-free survival (DFS) was comparable [P = 0.760, HR 0.93 (CI 0.60-1.45)] between the cisplatinum/5-FU group [11.1 months (CI 6.9-15.3)] and the carboplatin/paclitaxel group [9.7 months (CI 5.1-14.4)]. Groups were comparable except clinical T stage was higher in the carboplatin/paclitaxel group (P = 0.008). High clinical T stage (cT4) was not related to OS and DFS in a univariate analysis (P = 0.250 and P = 0.201). A higher percentage of patients completed the carboplatin/paclitaxel regimen (82% versus 57%, P = 0.010). Hematological and nonhematological toxicity (≥grade 3) in the carboplatin/paclitaxel group (4% and 18%) was significantly lower than in the cisplatinum/5-FU (19% and 38%, P = 0.001). CONCLUSIONS: In this study, we showed comparable outcome, in terms of DFS and OS for carboplatin/paclitaxel compared with cisplatinum/5-FU as dCRT treatment in EC patients. Toxicity rates were lower in the carboplatin/paclitaxel group together with higher treatment compliance. Carboplatin/paclitaxel as an alternative treatment of cisplatinum/5-FU is a good candidate regimen for further evaluation.

OBJECTIVES: To evaluate the outcomes of patients with early stage glottic cancer (GC) treated with radiotherapy (RT). DESIGN, SETTING AND PARTICIPANTS: The current study report on a retrospective analysis of oncologic outcome of 1050 patients with T1-2N0 glottic cancer treated with radiotherapy. Prospective assessment of quality of life (QoL) and voice handicap index (VHI) was performed in all patients treated from 2006 onwards (n = 233). MAIN OUTCOME MEASURES: Local control (LC), regional control (RC), disease-free survival (DFS), overall survival (OS), quality of life and voice handicap index. RESULTS: After a median follow-up of 90 months (range 3-309), the actuarial rates of local control, regional control, disease-free survival and overall survival were 85%, 99%, 84% and 81% at 5 years and 82%, 98%, 80% and 61% at 10 years, respectively. On multivariate analysis, T2 tumours, smoking after radiotherapy and conventional radiation scheme correlated significantly with poor local control. Patients who continued smoking after radiotherapy had also significantly lower overall survival rates (OR 4.3, P < 0.001). Hypothyroidism was reported in 18% of patients. Slight and temporary deterioration of quality of life scores was reported. Patient-reported xerostomia and dysphagia at 48 months were -7.1 and -6.5, compared with baseline, respectively. Voice handicap index improved significantly from 37 at baseline to 18 at 48 months. Patients with T2b and those who continued smoking had significantly worse voice handicap index. CONCLUSIONS: In the current study, excellent outcome with good quality of life and voice handicap index scores were reported. T2 tumours, in particular T2b, and continuing smoking after radiotherapy correlated significantly with poor local control and worse voice handicap index.

Malignant cells in serosal effusions provide essential information about the extent of malignant disease. The main aim of this study was to examine the additional diagnostic value of DNA image cytometry for cases with uncertainty in the cytological diagnosis. In addition, the feasibility of automated nuclei detection was investigated. Out of 457 cases, 33 samples in 32 patients were diagnosed with "atypia" (probably benign) and 21 as "suspicious for malignancy." DNA image cytometry was performed on these 54 cases and on an additional group of 14 cytologically malignant cases. The results show that automatic classification is useful for separation of control cells, i.e., lymphocytes and neutrophilic granulocytes from other mononuclear cells. In 21 cases an insufficient number of control cells were measured. Seventy-two percent of the cytologic malignant cases were aneuploid. In contrast, in none of the cases with "atypia" and in only 2 of the cases "suspicious for malignancy" was aneuploidy present (2 of the remaining 32, 6%). From the cases with follow-up, a malignancy in the pleural fluid was present in 2 out of 17 cases with "atypia" and in 5 out of 10 with a "suspicious for malignancy" cytologic diagnosis, respectively. In conclusion, the additional diagnostic value of DNA image cytometry in cases with a cytological diagnosis of "atypia" or "suspicious for malignancy" is limited. Diagn. Cytopathol. 1999;21:112-116.

STUDY OBJECTIVE: To determine whether allergic sensitisation occurs more frequently in young children with an acquired cholesteatoma in comparison with young children without ear diseases. DESIGN: In this retrospective case-control study the allergic sensitisation of 43 children (age 0-10 years) who were operated for an acquired cholesteatoma was compared with the allergic sensitisation of children without ear pathology. SETTING: Otology department of the ORL clinic of the Academic Medical Centre of University of Amsterdam in the Netherlands. MEASUREMENTS: From all subjects a complete history examination was performed and stored in a database. To assess for the presence of allergic sensitisation in patients who underwent radical ear surgery because of an acquired cholesteatoma, and the control group a multiantgen radioallergosorbent test (RAST) was performed. The GraphPad Prism v 2.0. statistical software was used to perform the analyses. RESULTS: Eighteen subjects (41.8%) demonstrated sensitivity to allergens and this is statistically significant (P < 0.0047) higher than the control group and expected for the general paediatric population. 80% of the patients with a positive multiantgen radioallergosorbent test were boys. In all positive cases an allergy for the house dust mite was determined. CONCLUSION: Allergy is statistically frequently present in paediatric patients with an acquired cholesteatoma. The house dust mite seems to be the most important allergen when allergy is involved with an acquired cholesteatoma. Cholesteatoma with an positive allergy test occurs much more often in boys than girls. This could mean that young boys with a series of inflammatory middle ear diseases and allergic sensitisation are probably more at risk to develop an acquired cholesteatoma in childhood.
