Abstract: Introduction: The role of elective nodal irradiation of non-small-cell lung cancer (NSCLC) patients treated with radiotherapy remains unclear. We investigated the significance of treating clinically uninvolved lymph nodes by retrospectively analyzing the relationship between loco-regional failure and the irradiated volume. Methods: Between 1998 and 2003, patients with IA–IIIB NSCLC were treated with radiotherapy. The eligibility criteria for this study were an irradiation dose of 60Gy or more and a clinical response better than stable disease. Typical radiotherapy consisted of 40Gy/20fr to the tumor volumes (clinical target volume of the primary tumor [CTVp], of the metastatic lymph nodes [CTVn], and of the subclinical nodal region [CTVs]), followed by off-cord boost to CTVp+n to a total dose 60–68Gy/30–34fr. The relationship between the sites of recurrence and irradiated volumes was analyzed. Results: A total of 127 patients fulfilled the eligibility criteria. Their median overall and progression-free survival times were 23.5 (range, 4.2–109.7) and 9.0 months (2.2–109.7), respectively. At a median follow-up time of 50.5 months (range, 14.2–83.0) for the surviving patients, the first treatment failure was observed in 95 patients (loco-regional; 41, distant; 42, both; 12). Among the patients with loco-regional failure, in-field recurrence occurred in 38 patients, and four CTVs recurrences associated with CTVp+n failure were observed. No isolated recurrence in CTVs was observed. Conclusions: In-field loco-regional failure, as well as distant metastasis, was a major type of failure, and there was no isolated elective nodal failure. Radiation volume adequacy did not seem to affect elective nodal failure. [Copyright &y& Elsevier]

Objectives: Chemoradiotherapy, which is one of the standard treatments for locally advanced pancreatic carcinoma, is considered a high-risk procedure in elderly patients. This study investigated the outcome and tolerability of this treatment in elderly patients. Methods: We reviewed our database from November 1993 to March 2003 and retrospectively examined the clinical data of patients with histologically confirmed exocrine pancreatic carcinomas that were nonresectable but confined to the pancreatic region, who were treated with protracted 5-fluorouracil infusion (200 mg/m2/day) and concurrent radiotherapy (50.4 Gy in 28 fractions over 5.5 weeks). We evaluated the outcome of patients ≥70 years and those <70 years. Results: There were 19 patients ≥70 and 39 patients <70. On pretreatment evaluation, the elderly patients showed lower serum albumin levels, lower transaminase levels, better ECOG performance status, more frequent body weight loss and less frequent abdominal and/or back pain with the administration of morphine than the younger patients. There were no significant differences in the frequency of severe toxicity. Neither the response rate nor the incidence of treatment discontinuation differed significantly between the two groups. The median survival time was longer in the elderly patients than in the younger patients (11.3 vs. 9.5 months, p = 0.04). Conclusions: With careful patient selection, chemoradiotherapy can be one of the treatment options for locally advanced pancreatic carcinoma in elderly patients. Copyright © 2005 S.

Purpose: To evaluate the effectiveness of small-field radiotherapy in combination with concomitant 5-fluorouracil (5FU) or cisplatin for locally advanced pancreatic carcinoma.Materials and methods: From November 1993 to January 1999, 53 patients underwent continuous 5FU infusion at 200 mg/m2 (27 patients) or a 30-min cisplatin infusion at 5 mg/m2/day (26 patients) just prior to each irradiation. The radiation field was limited to cover the primary and the paraaortic regions at celiac and supramesenteric axis levels. A total dose of 50.4 Gy in 28 sessions was given in 5.6 weeks.Results: Median and 1-year survival rates were 10.2 months and 35.2%, respectively. Local failure occurred in 19 patients (36%) and liver metastases in 16 patients (30%). All local recurrences occurred only within the radiation field.Conclusions: Median survival rates were comparable to other studies. Because local failure occurred only within the radiation field, the use of relatively small-field radiotherapy may be justified in the treatment of locally advanced pancreatic carcinoma in addition to concurrent administration of either 5FU or cisplatin.
