Abstract
BACKGROUND This review aims to assist cancer clinical researchers in choosing between the two most widely used measures of cancer-specific health-related quality of life: the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and Functional Assessment of Cancer Therapy-General (FACT-G). MATERIALS AND METHODS Information on QLQ-C30 and FACT-G content, scale structure, accessibility and availability was collated from websites and manuals. A systematic review was undertaken to identify all articles reporting on psychometric properties and information to assist interpretability. Evidence for reliability, validity and responsiveness was rated using a standardised checklist. Instrument properties were compared and contrasted to inform recommendations. RESULTS Psychometric evidence does not recommend one questionnaire over the other in general. However, there are important differences between the scale structure, social domains and tone that inform choice for any particular study. CONCLUSIONS Where research objectives are concerned with the impact of a specific tumour type, treatment or symptom, choice should be guided by the availability, content, scale structure and psychometric properties of relevant European Organisation for the Research and Treatment of Cancer versus Functional Assessment of Chronic Illness Therapy modules. Because the FACT-G combines symptoms and concerns within each scale, individual items should always be reviewed within the context of specific research objectives. Where these issues are indecisive, researchers are encouraged to use an algorithm at the end of the current article.

Abstract
8549 Background: Nasal NK/T-cell lymphoma is rare and its standard therapy has not been established. Tumor cells express P-glycoprotein concerning multi-drug resistance (MDR). Anthracycline-containing chemotherapy is not effective and %2-yr overall survival (OS) of radiotherapy (RT) alone is only 45%. Methods: To explore a more effective treatment for localized nasal NK/T-cell lymphoma, we conducted a phase I/II study of concurrent chemoradiotherapy consisted of 50 Gy of RT and 3 courses of DeVIC [carboplatin (CBDCA), etoposide (ETP), ifosfamide (IFM), dexamethasone (DMS)]. Patients (Pts) with newly-diagnosed, localized (IE & contiguous IIE with cervical node involvement) diseases, 20–69 years of age and PS 0–2 were eligible. The 3-D conformal RT planning was required to cover adequately target volumes (2 cm margin to gross tumor, entire nasal cavities and nasopharynx) and to minimize doses to organs at risk. Primary endpoint of the phase II portion was 2-yr OS and the enrollment of 24 pts to the phase II portion was planned. Based on the results of the phase I portion (ASH 2005, #2685), 2/3-dose of DeVIC (CBDCA 200mg/m2 d1 IV, ETP 67mg/m2 d1–3 IV, IFM 1.0g/m2 d1–3 IV, DMS 40mg/body d1–3 IV; every 3 wks) was applied for the phase II portion. RT quality assurance review confirmed no protocol violation (ASTRO 2008, #2682). Results: From Sep 2003 to Dec 2006, 33 pts were enrolled in the phase I/II study. 27 pts evaluated in the phase II portion showed the following features: age 21–68 yrs (median 56), M:F=17:10, stage IE 18, stage IIE 9, B symptom (+) 10, elevated serum LDH 5, PS2 2. With a median follow-up of 32 months (range, 24–62), %2-yr OS was 78% (95% CI, 57–89). Of 26 pts evaluable for response, 20 achieved CR, 1 PR, 2SD, and 3PD. %CR and %ORR were 77% (95% CI, 56–91) and 81%, respectively. The most common grade 3 non-hematologic toxicities were mucositis due to RT (30%) and infection (30%). Grade 4 hyponatremia and dermatitis due to RT were observed in each 1 pt. No treatment-related death was observed. Conclusions: Concurrent chemoradiotherapy using MDR-non-related agents and ETP is a safe and effective treatment for localized nasal NK/T-cell lymphoma, providing the basis for subsequent studies. No significant financial relationships to disclose.

Abstract
We present a case of advanced oesophageal cancer with cardiac invasion in an 84-year-old male presenting with dysphagia and general malaise. Histological analysis of an endoscopic biopsy specimen revealed a poorly differentiated squamous cell carcinoma. Computed tomography indicated a thickened oesophageal wall that was compressing the left atrium, suggesting invasion of the heart, and oesophagography revealed a polypoid lesion 9 cm in length. No distant metastases were seen on computed tomography. The patient was given chemotherapy with 10 mg/m2 cisplatin on days 1 and 4 every week for 5 weeks and concurrent radiotherapy at a dose of 2 Gy five times per week (total dose 52 Gy). After 4 weeks, the mass was no longer visible on oesophagography or endoscopic examination. The patient was free of recurrence and metastases for 4.5 years. In conclusion, chemoradiotherapy may be curative in elderly patients with unresectable oesophageal carcinoma.

Abstract
When breast-conserving therapy was introduced at the Cancer Institute Hospital (CIH) in Tokyo in 1986, we instituted our own strategy as follows: 1) every effort is to be made for complete tumor resection while avoiding deformity of the breast, and 2) radiotherapy (RT) is applied only to the patients with positive surgical margins. This is, in turn, to clarify the group of patients in whom postoperative RT can be safely spared. Among 9670 patients operated on for primary breast cancer during the 16.5 year period from 1986 to 2002 at CIH, there were 2449 patients who underwent breast-conserving surgery (BCS). During the 6.5 years mean follow-up period, ipsilateral intrabreast tumor recurrence (IBTR) developed in 99 of the 2449 patients, with an overall rate of 4.0% and an annual rate of 0.62%. These 2449 patients were categorized into four subgroups according to either negative or positive margins and with or without radiotherapy. The IBTR rates and the number of patients in each subgroup were 5.5% in 1351 margin(-)RT(-) patients, 1.0% in 307 margin(-)RT(+) patients, 2.4% in 680 margin(+)RT(+) patients, and 4.5% in 111 margin(+)RT(-) patients. These results either with or without RT seem to be quite comparable to or even better than the results of BCS with RT reported from Western countries, where less emphasis seems to be placed on completeness of the local tumor resection with BCS, while RT is administered to basically all patients following BCS. IBTR was categorized into true recurrence (TR) and second primary lesion (SP) according to the margin status at the time of BCS, the former being lesions developed in patients with positive margins and the latter being those in patients with negative margins. It was demonstrated that in patients with positive margins, TR was much more common than SP, whereas in patients with negative margins, these incidences were just the opposite (i.e., TR was 60% less common than SP) and postoperative RT was effective in preventing both TR and SP, the effect on the latter being much more striking. With RT, the incidence of developing TR in patients who had positive margins was reduced to almost equal to that in margin(-) patients treated with no RT. Our method of IBTR categorization is based on biological consideration and detailed histopathologic examination, and appears to be the only biologically reasonable means so far that has been proposed for distinction between these two biologically different entities. TR and SP can be further reduced to exceptionally low levels in patients who received RT despite negative margins, though it would not seem reasonable to administer RT to all of these patients because the actual number of patients who would benefit is comparatively small. From these observations, it seems that our imaging, pathologic examination, and surgical approaches for patients who are candidates for BCS have been highly valid, and our criteria for sparing postoperative RT as well as categorization of IBTR into TR and SP are quite appropriate. Although our results with BCS seem to deserve wide recognition, they are not from randomized clinical trials, so the findings must be confirmed by a study in order to investigate whether the results at CIH can be applied generally at other institutions.
